523 silcd/command_reply.[ch].
525 Sat Apr 6 17:08:58 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
527 * The LIST command reply in client libary now adds new channel
528 entry if the returned channel doesn't exist yet in cache,
529 and returns the channel entry to the application in the
530 command_reply client operation. Affected file is
531 lib/silcclient/command_reply.c.
533 * Changed the channel message payload's MAC generation to
534 include the IV in the MAC as well. This way all relevant
535 parts of the channel message payload are authenticated also
536 with the channel message MAC (and not only by packet MAC).
537 Causes incompatibility with 1.0 protocol. Protocol TODO #7.
538 Affected file is lib/silccore/silcchannel.c.
540 * Fixed the SKE to save the remote version, since the
541 silc_ske_parse_version mistakenly checked wrong version,
542 after it replaced the start payload. Affected files are
543 lib/silcske/silcske.[ch].
545 Fri Apr 5 16:03:03 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
547 * Splitted lib/silcutil/silcutil.h into silcstrutil.h for
548 string utility functions. Added there also new functions
549 silc_utf8_[encode/decode/valid] for UTF-8 string encoding.
550 Affected files lib/silcutil/silcstrutil.[ch].
552 * Renamed silc_*_pem functions to silc_pem_* functions. Affected
553 files are lib/silcutil/silcstrutil.[ch].
555 * Defined that the security property fields in SKE SHOULD be
556 UTF-8 encoded, defined that version string MUST be US-ASCII
557 encoded, defined that passphrases sent in connection
558 authentication protocol MUST be UTF-8 encoded. Implemented
559 these to the client and server. Defined also that other
560 passphrases sent in the protocol MUST be UTF-8 encoded.
561 Affected files are lib/silcske/silcske.c,
562 lib/silcclient/protocol.c, silcd/protocol.c,
563 silcd/serverconfig.c, and lib/silccore/silcauth.c.
565 * Changed the silc_client_close_connection interface to not
566 need the SilcSocketConnection which should not be visible
567 to application. Affected files are lib/silcclient/client.c
568 and lib/silcclient/silcclient.h.
570 * Rewrote the text for Private Message Key Payload in the
571 protocol specification. Protocol TODO #11.
573 Wed Apr 3 16:24:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
575 * Upgraded the protocol version to 1.1, updated protocol specs
578 * Added the nickname as new argument to NICK_CHANGE notify and
579 added it to protocol specs and implemented it to client and
580 server. Protocol TODO #3. Affected files are silcd/idlist.[ch],
581 silcd/command.c, silcd/packet_receive.c, packet_send.[ch], and
582 lib/silcclient/client_notify.c.
584 * Added the killer's client ID to the KILLED notify and added
585 it to protocol specs and implemented it to client and server.
586 Protocol TODO #13. Affected files are silcd/command.c,
587 silcd/packet_receive.c, packet_send.[ch],
588 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
589 The killer's client entry is now returned to application in
590 the `notify' client operation.
592 * Fixed the Max Argument fields that had too large value set
593 in the protocol specs. Protocol TODO #14.
595 * Added the LEAVE command reply to return the ID of parted
596 channel. Updated protocol specs and implemented it to the
597 client and server. Protocol TODO #15. Affected files are
598 silcd/command.c, lib/silcclient/command_reply.c. The channel
599 entry is now returned to application in the `command_reply'
602 * Rewrote the version SKE version checking in client libary
603 and in server to use the silc_parse_version_string. Affected
604 files are lib/silcclient/protocol.c, silcd/protocol.c.
606 * Added SILC_STATUS_ERR_NO_CHANNEL_FOPRIV error status to few
607 commands that was missing it, and updated protocol specs and
608 the server implementation. Protocol TODO #10. The affected
609 file is silcd/command.c.
611 * Defined new message flags SILC_MESSAGE_FLAG_REPLY to be
612 generic reply to a generic request (REQUEST flag), and
613 SILC_MESSAGE_FLAG_DATA to send any kind of data in a generic
614 way. A draft-riikonen-silc-flags-payloads-00.txt is written
615 to define the payload for DATA flag. Added the flags to
616 the implementation. Protocol TODO #9. Affected file is
617 lib/silccore/silcchannel.h.
619 Changed the client library to return the message length
620 to application as well in the channel_message and private_message
621 client operations. Affected files are
622 lib/silcclient/client_prvmsg, lib/silcclient/client_channel.c,
623 lib/silcclient/silcclient.h, irssi/src/silc/core/client_ops.c,
624 and lib/silcclient/client_ops_example.c.
626 * Added two new channel modes: SILC_CMODE_SILENCE_USERS
627 and SILC_CMODE_SILENCE_OPERS which can be used to moderate
628 the channel. Updated protocol specs and impelemented this
629 to client and server. Protocol TODO #6. Affected files are
630 silcd/packet_receive.c, server_util.c, lib/silcclient/command.c,
631 lib/silcclient/client_channel.c, lib/silccore/silcmode.h.
633 Added new options m and M to CMODE command in Irssi SILC
634 client to set these modes.
636 * Deprecated all administrative commands from SILC protocol
637 since they are highly implementation specific commands.
638 Updated protocol specs. Moved the old commands in
639 implementations to private range of command types. Affected
640 files are silcd/command.c, lib/silcclient/command.c and
641 lib/silcclient/command_reply.c. Protocol TODO #8.
643 * Fixed a bug in server where sending unknown command crashes
644 the server. Affected file silcd/command.c.
646 Wed Apr 3 09:57:47 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
648 * Added SILC_PROTOCOLVERSION macro to check protocol version
649 of a socket connection. The affected file is
650 lib/silcutil/silcsockconn.h.
652 * Added better error logging in rekey protocol. Affected file
655 * Do not check public key types in SKE during rekey. Affected
656 file lib/silcske/payload.c.
658 * Fixed the rekey protocol with PFS, which was totally broken.
659 Affected file silcd/protocol.c.
661 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
663 * Some client implementations quit network by doing first LEAVE
664 and then immediately SIGNOFF (like Bombyx). We now do check
665 after a short time after LEAVE notify and check whether the
666 client is still valid after LEAVE, and if not we remove it from
667 cache. Affected file is lib/silcclient/client_notify.c.
669 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
671 * Merged version 1.1.4 of zlib. Even if it not currently in use,
672 it's good not to have security holes here.
674 * Fixed a negative refcount situtuation for the config context.
675 Affected file is silcd/serverconfig.c.
677 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
679 * ROBOdoc documented lib/silcutil/silcutil.h.
681 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
683 * Optimized even more the SilcPacketContext structure. Now
684 totally saved 16 bytes of memory per context after optimization.
685 Affected files are lib/silccore/silcpacket.[ch].
687 * Made strict checks for valid SILC IDs. Affected file is
688 lib/silccore/silcid.c.
690 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
692 * Changed the object argument for silc_cipher_register,
693 silc_hash_register, silc_hmac_register and silc_pkcs_register
694 to const. Affected files are lib/silccrypt/silccipher.[ch],
695 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
697 * Changed the silc_get_username and silc_get_real_name to
698 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
700 * Fixed the Irssi SILC Client to use the silc_get_username and
701 silc_get_real_name insted of glib routines since the glib
702 routines only corrupt stack. Fixes the Irssi SILC to work in
703 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
705 * Fixed the Irssi to not use g_get_home_dir since it crashes
706 or returns garbage on cygwin and corrupts stack. Added function
707 get_home_dir to Irssi routines. Affected files are
708 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
710 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
712 * Made some structure optimizations. SFTP memory FS MemFSEntry
713 entry structure. Optimized SilcTask structure. Optimized
714 SilcPacketContext structure.
716 Affected files lib/silcsftp/sftp_fs_memory.c,
717 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
719 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
721 * And yet again reverted back the config thing since Johnny
722 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
725 * Fixed memory leaks from config object. Affected files are
726 silcd/serverconfig.[ch].
728 * Added support for adding new connections to the server in rehash.
729 After rehash they take effect.
731 Added support for changing the maximum allowed connections in
732 rehash. The number can grow but going smaller is not supported.
734 Added function silc_server_num_sockets_by_remote to the
735 silcd/server_util.[ch].
737 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
739 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
741 * Added preliminary checking during config parsing for a valid
742 public/private key and removed further checks in the code.
743 Affected files are silcd/serverconfig.[ch], server.c.
745 * Moved functions silc_server_drop() and silc_server_daemonise()
746 from server.c to silcd.c since they are stricly related to
747 the application activity.
749 * Reverted a small part of the automatic ref/unref since
750 it caused a double unref in some situations. Affected
751 files are silcd/silcd.[ch], server.c, serverconfig.c.
753 * Added some .cvsignore files in the lib directory.
755 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
757 * Fixed silc_net_gethostbyaddr to correctly resolve by
758 address. Affected file lib/silcutil/silcnet.c.
760 * Fixed the notify relaying to client. The HMAC to be used
761 with relayed packets ws wrong and caused decryption failure
762 at the client end. Affected file is silcd/packet_receive.c.
764 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
766 * Created new branch silc_protocol_1_0_branch.
768 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
770 * Changed the silc_server_config_* routines to be SilcServer
771 independent. They are now officially application specific code
772 and not part of generic server implementation. Affected files
773 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
775 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
777 * Added automatic referencing of config context in the
778 silc_server_config_alloc, and automatic unreferencing in the
779 silc_server_config_destroy. Affected files are
780 silcd/serverconfig.[ch], silcd/silcd.c.
782 * Fixed the silc_log_quick handling in the logging routines.
783 It didn't log quickly when it was TRUE. Affected file is
784 lib/silcutil/silclog.c. Also the flush delay was set even
785 if it was 0 in config file. Affected file is
786 silcd/serverconfig.c.
788 * Added support for changing key pair of the server in rehash.
789 Affected file silcd/server.c.
791 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
793 * Fixed the TOPIC_SET notify to not cras. It changed the topic
794 too early, before getting the channel entry. Affected file
795 is silcd/packet_receive.c.
797 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
799 * Added functions silc_server_config_[ref/unref], these are used
800 to prevent that the config object is destroyed.
802 No longer directly affect global variables silc_log_quick and
803 silc_log_delay, they are first cached inside the config object
804 and then applied with silc_server_config_setlogfiles().
806 silc_server_config_set_defaults() is now internal to
807 serverconfig.c, there are no reasons to show this internal stuff
810 Affected files are silcd/serverconfig.[ch].
812 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
813 fprintf's to stderr, since some code may be executed again after
814 the server went into the background. Affected files are
817 * Added rehash support. Added function silc_server_rehash() that
818 will perform all the basic tasks of the rehashing procedure.
820 * Added command line option `-x, --hexdump'. This will enable the
821 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
822 The option `--hexdump' implies `--debug'.
824 * Fixed a bad bug in the logging APIs (silcutil library) where
825 the application would crash after calling silc_log_reset_all().
827 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
829 * Fixed the KICKED notify handling in client library to
830 correctly remove the channel and all entries from the
831 channel when I was kicked. This bug crashed the client.
833 Fixed yet another but in KICKED notify handling to remove
834 the kicked client correctly from the channel.
836 Affected file is lib/silcclient/client_notify.c.
838 * Fixed a minor bug in looking up correct client entry
839 in KICKED notify in server. Affected file is
840 silcd/packet_receive.c.
842 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
843 sources correctly to distribution. Fixes --with-gmp option.
845 * Removed the manual rehashing from ID Cache, and changed it
846 to use the SILC Hash Table's auto rehash feature. Affected
847 file is lib/silccore/silcidcache.c.
849 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
851 * Fixed a bug in the silc_client_nickname_format function that
852 handles the multiple same nickname formatting. Two clients
853 with same nickname caused problems after the first one left
854 and rejoined. It didn't format the nickname correctly.
855 Affected file is lib/silcclient/idlist.c.
857 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
859 * Don't change the topic if olod topic is same as new one.
860 Affected file is silcd/packet_receive.c.
862 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
864 * Added cross-reference support to the SILC Documentation
865 generator. All types across all HTML files are now cross-
866 referenced. Affected files util/robodoc/generator.c and
867 scripts/silcdoc/silcdoc.
869 * Added file lib/silcutil/silctypes.h to include all the
870 arithmetic type definitions and some macros. Removed
871 includes/bitmove.h and moved macros to silctypes.h.
873 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
875 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
877 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
879 * Added `type' argument to silc_id_payload_parse_id function which
880 now returns the type of the ID to the sent pointer. Affected
881 file is lib/silccore/silcid.[ch].
883 * Added check for CMODE_CHANGE notify type that mode change is
884 allowed by the sender. Affected file silcd/packet_receive.c.
886 * Added check for CUMODE_CHANGE notify type that mode change is
887 allowed by the sender. Affected file silcd/packet_receive.c.
888 Added the ID type as CUMODE_CHANGE notify type as argument
889 to the `notify' client operation. Affected files are
890 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
892 * Added function silc_client_add_server to the client library.
893 Added support for resolving also channel and server info when
894 received unknown entity in notify packet. Affected files are
895 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
897 * Added function silc_command_get_status to return the command
898 status from the command reply's argument payload. Affected files
899 are lib/silccore/silccommand.[ch].
901 * Added check for KICKED notify type that the kicking is
902 allowed by the client. Affected file silcd/packet_receive.c.
904 * Created function silc_get_input which can be used to get input
905 (echo on or off) from user on command line. Affected files are
906 lib/silcutil/silcutil.[ch].
908 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
910 * Optimized silc_server_packet_relay_to_channel function.
911 Added new function silc_channel_message_payload_encrypt which
912 can be called directly if channel message payload needs to
913 be encrypted and is already encoded (no need to call _encode
914 function). Packet relaying is now done by router without any
915 extra memory allocations. Affected files are
916 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
919 * Fixed the INVITE notify handling. It took wrong arguments
920 as invite list and invite delete. Affected file is
921 silcd/packet_receive.c.
923 * Added check for TOPIC_SET notify type that the topic change is
924 allowed by the client. Affected file silcd/packet_receive.c.
926 * Added check for INVITE notify type that inviting is allowed by
927 the client. Affected file silcd/packet_receive.c.

931 silc_server_check_cmode_rights to server_util.[ch].
932 Affected files are silcd/server_util.[ch], silcd/command.c.
934 * Added function silc_server_check_umode_rights to check whether
935 changing client's user mode is allowed. Added check for
936 UMODE_CHANGE notify type that the umode change is allowed
937 by the client. Affected files are silcd/server_util.[ch],
938 silcd/packet_receive.c and silcd/command.c.
940 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
942 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
943 ID length. It ignored that ID can be IPv6 based as well.
944 Affected file lib/silccore/silcpacket.h.
946 * Fixed the silc_id_id2str and silc_id_str2id to take the
947 IPv6 address offset's into consideration. Affecte file is
948 lib/silccore/silcid.c.
950 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
952 * Fixed the internal Unix scheduler functions to check for
953 NULL context they may receive. The affected file is
954 lib/silcutil/unix/silcunixschedule.c.
956 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
958 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
959 can specify different directory with --home command line
960 parameter. Affected files irssi/src/silc/core/client_ops.c,
963 * SILC-specific commands aren't now executed if the active server
964 isn't of SILC-type, so there won't be problems with having
965 IRC and SILC protocol support in same client. Affected files
966 irssi/src/silc/core/silc-channels.c, silc-servers.c,
969 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
971 * Improved the signal support in SILC Schedule. Added new
972 function silc_schedule_signal_call which is used by application
973 to mark a signal to be called. It is now safe to perform
974 any kind of tasks in signal callbacks since it is guaranteed
975 that the application specified signal callback is called
976 after the signal is over. Affected files are
977 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
979 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
981 * Added `name' field to SilcChannelPrivateKey to represent
982 application given name for the key. Moved also the context from
983 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
984 Added the `name' argument also to the function
985 silc_client_add_channel_private_key.
987 Added function silc_client_current_channel_private_key to set the
988 current channel private key in use.
990 Added "change" command to KEY command which can be used to change
991 the current channel private key. Bound the command also to
994 Also affected files lib/silcclient/client_channel.c,
995 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
997 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
999 * Added silc_rng_get_byte_fast function in to the
1000 lib/silccrypt/silcrng.[ch].
1002 * Changed the interface of silc_packet_assemble and the
1003 silc_packet_send_prepare. If silc_packet_assmble is now
1004 called the application does not call silc_packet_send_prepare
1005 because the library will call it automatically. These
1006 interfaces now also return a reference to the outgoing buffer
1007 which includes the assembled packet, which the application can
1008 use to encrypt the packet.
1010 Affected files are lib/silccore/silcpacket.[ch],
1011 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
1012 silcd/packet_send.c, server_backup.c and packet_receive.c.
1014 * Fixed a packet sending bug on very high load, where outgoing
1015 packet queue wasn't handled correctly and packets got corrupted.
1016 Affected files are lib/silcutil/*/silc*sockconn.c,
1017 lib/silcclient/client.c and silcd/server.c.
1019 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1021 * Added macro SILC_PACKET_DATALEN which can be used during
1022 packet assembling to check whether the data to be added to
1023 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
1024 len is truncated until it fits it.
1026 Added checks for maximum length of channel message payload and
1027 private message payload also.
1029 Added checks for maximum packet length in server and in
1032 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
1033 lib/silcclient/client.c, lib/silccore/silcchannel.c and
1034 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
1035 lib/silcclient/client_prvmsg.c.
1037 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1039 * Added silc_server_packet_queue_purge call to the
1040 silc_server_disconnect_remote to assure that all data in the
1041 queue before disconnecting is sent to the network. Affected
1042 file silcd/server.c.
1044 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1046 * Added the deleting of server's own ID cache entry to the
1047 silc_server_free function. Free also everything else that
1048 has been allocated in silc_server_init. The affected file
1051 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1053 * Added functions silc_parse_version_string, silc_version_to_num,
1054 and silc_ske_parse_version to parse SILC protocol style version
1055 strings. Affected files lib/silcutil/silcutil.[ch] and
1056 lib/silcske/silcske.[ch].
1058 * Added new configuration params: version_protocol, version_software
1059 and version_software_vendor to specify what version the remote
1060 host must at least be to be able to connect to server. The vendor
1061 string can be regex matched too. Added new function
1062 silc_server_connection_allowed to check maximum number of allowed
1063 connections, and allowed versions for incoming connections.
1064 Affected files are silcd/server.c, server_util.[ch] and
1067 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1069 * Added preliminary support for signals in scheduler. The
1070 signals we care about are now blocked always when the scheduler
1071 is locked. This way we can synchronise the use of signal with
1072 scheduler. It is guaranteed that when signal occurs the scheduler
1073 is not locked, and thus new tasks can be safely added to the
1076 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
1077 to silc_schedule_internal_init and silc_schedule_internal_uninit.
1078 Added new platform specific routines
1079 silc_schedule_internal_signals_[un]block and
1080 silc_schedule_internal_signal_[un]register.
1082 Added new functions to SILC Schedule API:
1083 silc_schedule_signal_[un]register. Each signal that application
1084 is going to use should be registered to the scheduler.
1086 Affected files are lib/silcutil/silcschedule.[ch],
1087 lib/silcutil/*/silc*schedule.c.
1089 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1091 * Check for unauthenticated client and server in the
1092 silc_server_new_client and silc_server_new_server functions.
1093 Affected file silcd/packet_receive.c.
1095 * Added function silc_string_is_ascii to check whether given
1096 string is 7-bit ASCII string. Affected files are
1097 lib/silcutil/silcutil.[ch].
1099 * Added function silc_id_is_valid_server_id into the
1100 silcd/serverid.c and added checking for valid Server ID's in
1101 silc_server_new_server. The Server ID must always be based
1102 on the server's public IP address.
1104 * Added logging of DISCONNECT packet message in the server.
1105 Affected file silcd/server.c.
1107 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1109 * Changed all library interfaces that use Global RNG to also
1110 accept SilcRng as argument. Affected files are
1111 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
1112 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
1113 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
1114 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
1115 lib/silccrypt/rsa.c.
1117 * Added function silc_pkcs_generate_key to the
1118 lib/silccrypt/silcpkcs.[ch] for applications so that they
1119 don't need to do pkcs->pkcs->init calls anymore.
1121 * Remove SilcSocketConnection from the SFTP API since it really
1122 wasn't needed there. The application has the information
1123 saved in its contexts anyway and the SFTP layer doesn't need
1124 know about it. Affected files lib/silcsft/silcsftp.h and
1125 lib/silcsftp/sftp_[server/client].c.
1127 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
1128 The SilcSimContext is not SilcSim.
1130 * Fixed possible buffer overflows in silc_id_render in the
1131 lib/silcutil/silcutil.c.
1133 * On EPOC the global crypto module lists are not used at all
1134 in the crypto library. Added support for using the constant
1135 algorithm list on EPOC. Affected files are
1136 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
1139 * Fixed the handling of third parameter of KICKED notify, since
1140 it was mistakenly updated to SILC Protocol 1.0 even though it
1141 is to be included in 1.1. Since it is not in 1.0 it is not
1142 mandatory, and this fix now handles it only if it is provided,
1143 and it is not error if it is not provided. Affected file
1144 lib/silcclient/client_notify.c.
1146 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1148 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
1149 client. Affected file irssi/src/silc/core/client_ops.c.
1151 * Merged with Irssi 0.8.4 from irssi.org CVS.
1153 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1155 * Check for valid socket connection in client entries before
1156 sending any messages. Fixes a crash, but doesn't fix some
1157 other underlaying bug that is lurking there. Affected
1158 file silcd/packet_send.c.
1160 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
1162 * $usermode, $cumode and $cumode_space expandos shouldn't do
1163 anything with non-SILC server records. Affected file
1164 irssi/src/silc/core/silc-expandos.c
1166 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1168 * Fixed the silc_net_check_[host/local]_by_sock to support
1169 IPv6 bound sockets as well. Now they can return IPv6 addresses
1170 as well. Affected file lib/silcutil/silcnet.c.
1172 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
1173 Affected lib/silcutil/unix/silcunixnet.c.
1175 * Fixed ID rendering (at least on some platforms, not NetBSD)
1176 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
1178 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1180 * Added silc_hash_public_key and silc_hash_public_key_compare
1181 functions to be used with SilcHashTable. They can be used to
1182 hash public keys and compare public keys in hash table. Affected
1183 file lib/silcutil/silcutil.[ch].
1185 * Added support for specifying multiple public keys for Client
1186 connection section in server configuration file. This makes it
1187 possible to accept multiple public keys from same host, or to
1188 make a section that accepts any incoming host, and have the
1189 accepted public keys listed in the section.
1191 Added functions silc_sever_[find/get]_public_key, added the
1192 support for this actually to all connection sections but only
1193 the Client section is currently allowed to specify multiple
1196 Affected files are silcd/server.c, server_internal.h,
1197 command.c, protocol.c, server_util.[ch], packet_receive.c.
1199 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1201 * Merged Irssi 0.8.2 from irssi.org CVS.
1203 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1205 * If silc_debug is TRUE, also output standard logging messages
1206 to stderr with the debug output.
1208 Made silc_log_reset_all() flushing all channels before returning.
1209 Also fixed some documentation typos.
1211 Affected files are lib/silcutil/silclog.[ch].
1213 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1215 * Fixed the server to check correctly the amount of connections
1216 from single host, by checking also the type of the connection.
1217 Fixed also the comparison of number of connections and number
1218 of allowed connections. Affected files are silcd/server.c,
1221 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1223 * Fixed the USERS command reply to save the user's mode on the
1224 channel as well. Fixed JOIN command reply to check whether a
1225 client is on channel already and not join it twice. Affected
1226 file lib/silcclient/command_reply.c.
1228 * Added new file silc-expandos.c into irssi/silc/core/ to return
1229 various stuff for various signal for the statusbar etc. updating.
1230 Now Irssi SILC client prints channel user modes etc. on the
1233 * The user mode (like server/router operator changes) is now shown
1234 on the Irssi SILC client's statusbar. The affected files are
1235 irssi/src/silc/core/client_ops.c, silc-expandos.c.
1237 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1239 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
1240 to SILC_SCHEDULE_[UN]LOCK macros.
1242 * Added more error printing to logs in server code. Affected
1243 files silcd/server.c and silcd/protocol.c.
1245 * Fixed -S option parsing in Irssi SILC Client. Affected file
1246 irssi/src/silc/core/silc-core.c.
1248 * Added silc_buffer_alloc_size function. Affected file is
1249 lib/silcutil/silcbuffer.h.
1251 Tue Mar 5 14:37:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1253 * Changed all silc_[hash|hmac|cipher|pkcs]_default tables to
1254 constants. Affected files in
1255 lib/silccrypt/silcpkcs.[ch], silchash.[ch], silchmac.[ch] and
1258 * Changed the internal SFTP Memory FS table to const. Affected
1259 file lib/silcsftp/sftp_fs_memory.c.
1261 Sun Mar 3 18:37:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1263 * Fixed the buffer formatting and unformatting routines to
1264 check the size of 64 bits types with sizeof(). Affected
1265 file is lib/silcutil/silcbuffmt.c.
1267 Mon Feb 25 17:19:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1271 Sun Feb 24 12:53:25 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1273 * Changed all integer type names:
1274 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
1275 to avoid collisions with other libraries using same type names
1278 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1280 * Added `prefer_ipv6' argument to the functions
1281 silc_net_gethostbyname[_async]. If it is TRUE it will return
1282 IPv6 address over IPv4. If FALSE IPv4 address is returned
1283 even if IPv6 address was found. Affected files
1284 lib/silcutil/silcnet.[ch].
1286 * Added support silc_net_create_connection[_async] to fallback
1287 to IPv4 address if IPv6 address could not be used (like if
1288 it doesn't work on a specific system). Affected file in
1289 lib/silcutil/unix/silcunixnet.c.
1291 Sat Feb 23 15:20:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1293 * Added silc_schedule_reinit function to do the enlarging
1294 of the max tasks handling capabilities of the scheduler.
1295 Affected files lib/silcutil/silcschedule.[ch].
1297 Wed Feb 20 20:41:01 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1299 * Added automatic extern "C" { ... } for C++ compilers so the
1300 application does not need to define them. Affected file
1301 includes/silcincludes.h.
1303 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
1304 old name went against naming convention. Applications now
1305 include "silcclient.h" instead of "clientlibincludes.h".
1306 Removed includes/clientlibincludes.h, it is redundant now.
1308 * Renamed includes/version.h to silcversion.h.
1310 * Added really preliminary support for OS/2 into the util
1311 library. Only thread & mutex API is implemented, others
1312 are still to be implemented. Created the lib/silcutil/os2/
1313 directory. Created also file includes/silcos2.h.
1315 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1317 * Added preliminary BeOS support into the util library.
1318 Created lib/silcutil/beos/, and implemented all the needed
1319 functions to support SILC on BeOS. Created also file
1320 includes/silcbeos.h.
1322 Mon Feb 18 15:49:22 EET 2002 Timo Sirainen <tss@iki.fi>
1324 * Added proper initializations to silc's irssi code, so it's
1325 now possible to load it as module. Affected files
1326 irssi/src/silc/core/silc-core.c,
1327 fe-common/silc/fe-common-silc-core.[ch] and fe-text/silc.c
1329 Sun Feb 17 19:02:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1331 * Merged latest Irssi (0.8.1) from the irssi.org's CVS into
1334 * Fixed the silcdoc document generator to correct generate
1335 docs from all kinds of filenames. Affected files are

1346 * Added `user_count' to the SilcChannelEntry which now tells the
1347 number of users on the channel. The user count is now saved
1348 in normal server of global channels as well. Affected files
1349 silcd/server.c, idlist.h, packet_receive.c and command.c.
1351 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
1352 include file utility functions.
1354 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
1355 instead of calling directly OS routines.
1357 * Fixed NICK change printing in Irssi SILC Client. Fixed
1358 KICKED notify printing in Irssi SILC Client. Affected file
1359 irssi/src/silc/core/client_ops.c.
1361 * Fixed a NICK change bug in client library, to not recreate the
1362 client_entry->channels hash table everytime nick is changed.
1363 Affected file lib/silcclient/client.c.
1365 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1367 * ROBOdoc documented the lib/silcske/silcske.h, and improved
1368 the SKE interface a bit.
1370 * Fixed padding problem in PKCS#1. The padding was not actually
1371 random since the random number generator was used incorrectly.
1372 This security bug affects only when encrypting with PKCS#1, and
1373 it is not currently used at all in SILC. SILC only use signing
1374 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
1376 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1378 * Rewrote the notify handling in Irssi SILC client to not call
1379 the events as signals. Fixes problems with Perl support.
1380 Affected files irssi/src/silc/core/client_ops.c, silc-channels.c.
1382 * Send the auto-nicking NICK command in client library with
1383 little timeout after connecting. The affected file is
1384 lib/silcclient/client.c.
1386 * Added following new config file settings:
1387 channel_rekey_secs, key_exchange_rekey, key_exchange_pfs,
1388 key_exchange_timeout, conn_auth_timeout, connections_max,
1391 Implemented all the new config settings handling in the server.
1393 Optimized the use of SKE Mutual flag usage. Use it only
1394 if connection authentication protocol is not based in public
1397 Renamed all SilcServerConfigSection* to SilcServerConfig*
1398 to have a bit shorter names.
1400 Affected files silcd/serverconfig.[ch], server.[ch], and
1403 Sat Feb 16 02:46:43 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

1418 * Fixes to the silcd config template. Affected file is
1419 doc/example_silcd.conf.in.
1421 * Removed type casts from silc_calloc(), conforming to the
1422 CodingStyle. Affected file is lib/silcutil/silcconfig.c.
1424 * Removed param_name member from client, server, and router
1425 section structs, now identifying the param directly.

1429 Affected files are silcd/serverconfig.[ch].
1431 Fri Feb 15 12:24:08 EET 2002 Timo Sirainen <tss@iki.fi>
1433 * Fixed command line parameter handling. All SILC initialization
1434 is now done in silc_core_init() which also fixes autoconnecting
1437 Affected files irssi/src/silc/core/silc-core.c,
1438 irssi/src/fe-text/silc.c.
1440 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1442 * Added new configuration options and blocks:
1443 keepalive_secs, reconnect_count, reconnect_interval,
1444 reconnect_interval_max, reconnect_keep_trying and
1445 require_reverser_lookup. Added ConnectionParam block, and
1446 implemented the connection parameters when connecting as
1447 initiator and when accepting connections as responder.
1449 Added CONFIG_IS_DOUBLE macro in config file parsing, to check
1450 whether given configuration value has been given already.
1452 Affected files silcd/serverconfig.[c], server.[c].
1454 * Splitted the doc/example_silcd.conf.in. Separated the crypto
1455 algorithm parts and created new file silcalgs.conf, that
1456 is now included from the example_silcd.conf.in.
1458 * Optimized the silc_server_connect_to_router_second to take
1459 the connection configuration object from the SilcServerConnection
1460 object instead of finding it during the connecting phase.
1461 Added the configuration object to SilcServerConnection struct.
1462 Affected files silcd/server_internal.h, server.c.
1464 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1466 * Add the client on channel after it was resolved at the
1467 channel message receiving, and it was not already on the
1468 channel. Affected file lib/silcclient/client_channel.c.
1470 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1472 * Fixed the public key authentication to allocate always the
1473 destination signature buffer instead of using static buffer.
1474 Affected file silcd/protocol.c.
1476 Wed Feb 13 20:51:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1478 * Unified the serverconfig.[ch]'s helper function interface.
1479 Affected file silcd/serverconfig.[ch].
1481 * Removed doc/example_silc.conf.in since it is redundant.
1482 The make install will now install irssi/silc.conf file.
1484 * Added new Passphrase and Publickey authentication methods to
1485 config file, allowing both public key and passphrase based
1486 authentication to be set at the same time.
1488 Added `prefer_passphrase_auth' setting in config file which
1489 can be used to set to prefer passwd auth if both passwd and
1490 public key is set. If not set, public key is preferred.
1491 This has effect only when being initiator (responder will try
1494 Added support for authentication with passphrase and public key
1495 at the same time. The passphrase is tried first always since
1496 it is faster to check.
1498 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
1500 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1502 * Merged the new SILC Config library, with the server parsing
1503 support. Read the header file silcconfig.h or the toolkit
1504 documentation for the news. Affected files are

1511 lib/silcutil/silclog.h.
1513 Sun Feb 10 18:11:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1515 * The silc_cipher_register, silc_hash_register and
1516 silc_hmac_register now checks if the object to be registered
1517 is registered already. Affected files are
1518 lib/silccrypt/silccipher.c, silchash.c and silchmac.c.
1520 Sun Feb 10 15:48:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1526 * Allow zero length channel messages inside the Channel Message
1527 Payload. Affected file lib/silccore/silcchannel.c.
1529 * Fixed scripts/silcdoc/silcdoc to support all kinds of filenames
1530 as header filenames.
1532 * Removed lib/silcclient/README and created HTML file
1533 lib/silcclient/silcclient_using.html, which is now included
1534 as part of Toolkit documentation.
1536 Thu Feb 7 10:12:25 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1538 * Fixed CUMODE_CHANGE notify handling to change the mode of
1539 correct client. Affected file lib/silcclient/client_notify.c.
1541 * Make silc_rng_alloc fail if it cannot allocate the sha1
1542 hash algorithm. Affected file lib/silccrypt/silcrng.c.
1544 Sun Feb 3 17:20:52 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1546 * Fixed the file transfer's key agreement payload to include
1547 zero port also if the hostname is NULL because it could not
1550 Call file transfer monitor callback now also if error occurs
1551 during key agreement protocol.
1553 Changed the silc_client_file_send interface to return the
1554 SilcClientFileError instead of session id. The session ID
1555 is returned into pointer provided as argument.
1557 Check that the file exists locally before sending the
1558 file transfer request at all.
1560 Affected file lib/silcclient/client_ftp.c, silcapi.h.
1562 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer
1563 error than can occur while key agreement protocol. Affected
1564 file lib/silcclient/silcapi.h.
1566 * Fixed the event_mode CMODE handler to not crash when mode
1567 is changed and +k mode is set in the channel. Affected file
1568 irssi/src/silc/core/silc-channels.c.
1570 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
1571 SILC_LOG_WARNING to give out Warning and not Error. Affected
1572 file lib/silcutil/silclog.c.
1574 * Fixed the channel message payload decryption in the function
1575 silc_channel_message_payload_decrypt to not modify the original
1576 buffer before it is verified that the message decrypted
1577 correctly. Otherwise, next time it is called with correct
1578 channel key it won't encrypt since the payload is corrupted.
1579 Affected file lib/silccore/silcchannel.c.
1581 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1583 * Do not constantly resize the window. A fix patch by cras.
1584 Affected file irssi/src/fe-text/screen.c.
1586 Sat Feb 2 16:54:18 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1588 * Applied IPv6 fix patch from Jun-ichiro itojun Hagino.
1589 Affected file lib/silcutil/silcnet.c.
1591 Fri Feb 1 22:33:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1593 * Fixed a bug in hash table internal routine for traversing
1594 the table with foreach callback. The current entry may
1595 become invalid in the callback but it was referenced after
1596 the callback returned.
1598 Do not allow auto rehashing of hash table during the
1599 silc_hash_table_foreach operation, for same reasons as it is
1600 not allowed for SilcHashTableList. Affected files are
1601 lib/silcutil/silchashtable.[ch].
1603 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1605 * Defined DLLAPI into silcincludes.h and silcwin32.h for
1606 Win32 DLL. extern's in header files are now declared with
1609 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1611 * Fixed private message handling. It used some old code that
1612 caused the client to crash. Affecte file is
1613 lib/silcclient/client_prvmsg.c.
1615 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1617 * Added function silc_client_add_channel,
1618 silc_client_replace_channel_id, and removed functions
1619 silc_client_new_channel_id and silc_idlist_get_channel_by_id
1620 from client library.
1622 * Added cross reference of the joined channels to the
1623 SilcClientEntry, and changed the SilcChannelEntry's
1624 users list to SilcHashTable. The affected files are
1625 lib/silcclient/idlist.[ch].
1627 * Fixed a bug in hash table tarversing. While the hash table
1628 is traversed with SilcHashTableList the table must not be
1629 rehashed. It is now guaranteed that auto rehashable tables
1630 are not rehashed while tarversing the list. Also defined that
1631 silc_hash_table_rehash must not be called while tarversing
1632 the table. Added function silc_hash_table_list_reset that must
1633 be called after the tarversing is over. The affected files are
1634 lib/silcutil/silchashtable.[ch].
1636 * Changed all hash table traversing to call the new
1637 silc_hash_table_list_reset in server and in client library.
1639 * Added function silc_client_on_channel to return the
1640 SilcChannelUser entry if the specified client entry is joined
1641 on the specified channel. This is exported to application as
1642 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
1644 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1646 * Fixed founder regaining problem with JOIN command on normal
1647 server. The notify for mode change must be sent always and
1648 not only if !cmd->pending. Affected file silcd/command.c.
1650 * Fixed the WHOWAS command's reply sending to support the
1651 lists correctly. Affected file silcd/command.c.
1653 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1655 * When sending JOIN command to router for processing the
1656 sender's old command identifier was not saved back to the
1657 sender's command context, fixed now. The affected file is
1660 * Create the key in JOIN command of the router did not return
1661 the channel key, added check for this. Affected file is
1664 * Fixed a channel ID update bug in JOIN command reply. Do
1665 not directly upgrade the ID but call the function
1666 silc_idlist_replace_channel_id if the ID was changed.
1667 Affected file silcd/command_reply.c.
1669 * Fixed memory leaks from command calling if it would fail.
1670 Affected file silcd/command.c.
1672 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1674 * Applied patches from cras:
1676 Memory leak fixes around libaries, irssi window resize fix,
1677 new silclist.h and silcdlist.h, all extern inline changed to
1680 * Removed dotconf from lib/dotconf, not needed anymore.
1682 * Removed TRQ from lib/trq, not needed anymore.
1684 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
1685 with server connections. Later this will be configurable
1686 in config file after new config file is done. Affected file
1689 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1691 * Fixed a crash in server related to channel announcements.
1692 Affected file silcd/server.c.
1694 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1696 * Fixed memory leaks in silc_server_create_new_channel*
1697 functions. Affected file silcd/server.c.
1699 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
1700 which ID was changed. This way the router will send the
1701 user list for the channel again, and server won't be in
1702 desync in some rare circumstances. Affected file is
1703 silcd/packet_receive.c.
1705 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1707 * Check for NULL socket pointer in the function
1708 silc_server_packet_send_to_channel_real. Affected file
1709 silcd/packet_send.c.

1712 list. Affected file silcd/packet_receive.c.
1714 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1716 * Fixed some header addition to Toolkit distribution in
1717 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
1719 * Added lib/silcclient/client_ops_example.h as an template
1720 file for application programmers to quickly start using
1721 the SilcClientOperation functions in their application.
1722 Updated the lib/silcclient/README as well to tell about this
1723 nice file made available.
1725 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1727 * Call silc_server_remove_from_channels when removing client
1728 entry when NO_SUCH_CLIENT_ID was received. Affected file
1729 is silcd/command_reply.c.
1731 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1733 * Added server & router operator statistics updating. Affected
1734 file silcd/packet_receive.c and silcd/command.c.
1736 * Fixed the SERVER_SIGNOFF notify handling on normal server
1737 not to save the history information for clients. Same was
1738 fixed earlier in remove_clients_by_server function, but not
1739 here. Affected file silcd/packet_receive.c.
1741 * Raised the default connection-retry count from 4 to 7 in
1742 server. Affected file silcd/server.h.
1744 * Cancel any possible reconnect timeouts when we start the
1745 key exchange. Affected file silcd/server.c.
1747 * Do not reconnect on connection failure when SCONNECT was
1748 given. Affected files silcd/server.[ch].
1750 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1752 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
1754 * Fixed the NICK command to always give the unformatted
1755 nickname to the one giving the NICK command. If unformatted
1756 nickname is cached already it will be formatted and the
1757 local entry will always get the unformatted nickname.
1758 Affected file lib/silcclient/idlist.c.
1760 * Fixed some double frees from client library commands.
1761 Affected file is lib/silcclient/command.c.
1763 * Fixed CUMODE command in server to assure that no one can
1764 change founder's mode than the founder itself, there was a
1765 little bug. Affected file silcd/command.c.
1767 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1769 * Removed the SilcClientCommandDestructor from the client
1770 libary, it is not needed anymore. Affected files are
1771 lib/silcclient/silcapi.h, command[_reply].[ch],
1772 client_notify, idlist.c.
1774 * Fixed GETKEY command to first resolve client, and then
1775 resolve the server only if the client was not found, instead
1776 of resolving both at the same time. Affected file is
1777 lib/silcclient/command.c.
1779 * Added silc_client_start_key_exchange_cb and lookup the
1780 remote hostname and IP address before starting the key
1781 exchange with server. The affected file is
1782 lib/silcclient/client.c.
1784 * The server's public key is now saved using the IP address
1785 of the server and not the servername for the filename.
1786 The hostname public key filename is checked as an fall back
1787 method if the IP address based filename is not found.
1789 Fixed the GETKEY command to save the fetched server key
1790 in correct filename.
1792 Print the remote server's hostname now when new key is
1793 received during connection process. Affected file is
1794 irssi/src/silc/core/client_ops.c.
1796 * Return always our own public key to the client if it asks
1797 for it with GETKEY command. Affected file silcd/command.c.
1799 * Removed the use_auto_addr variable from default config
1800 file since it was in wrong section. Affected file is
1803 * Fixed TOPIC_CHANGE notification to not route it when it
1804 was sent using silc_server_send_notify_to_channel function.
1805 Affected file silcd/command.c.
1807 * Fixed silc_server_send_notify_kicked to send the kicker's
1808 Client ID also, it was missing. Affected files are
1809 silcd/command.c, silcd/packet_send.[ch].
1811 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1813 * Do not save client history information in SERVER_SIGNOFF.
1814 Fixes the bug in normal server that it does not detect
1815 the client becoming valid after the server becomes back
1816 online. Affected file silcd/server_util.c.
1818 * Added `sock_error' field into the SilcSocketConnection
1819 context. When error occurs during socket operation (read
1820 or write) the error is saved. Added also new function
1821 silc_socket_get_error to return human readable socket error
1822 message. Affected files are lib/silcutil/silcsockconn.[ch],
1823 lib/silcutil/unix/silcunixsockconn.c, and
1824 lib/silcutil/win32/silcwin32sockconn.c.
1826 * The server now prints the socket error message in the
1827 signoff for client. Affected file silcd/server.c.
1829 * Fixed the `created' channel information sending from router
1830 to server in JOIN command. Checks now whether the channel
1831 really was created or not and set it according that.
1833 Fixed the JOIN command to use the client entry's current
1834 ID during the joining procedure instead of the one it sent
1835 in the command (it is checked though), since it can change
1836 between the packet processing and command processing, and
1837 would just case unnecessary pain in the client end. Affected
1838 file silcd/command.c.
1840 * Fixed a channel key payload sending to use correct channel
1841 ID when the server was forced to change the channel's ID by
1842 router. Router sent the key payload with the old Channel ID.
1843 Affected file silcd/packet_receive.c.
1845 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1847 * Call silc_server_save_channel_key only if the key payload
1848 was provided in the JOIN command's command reply. Affected
1849 file silcd/command_reply.c.
1851 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1853 * Fixed silc_mp_sizeinbase to return the value correctly with
1854 MPI. Affected file lib/silcmath/mp_mpi.c.
1856 * Fixed the stop_server signal to correctly stop the scheduler
1857 and gracefully stop the server when SIGTERM or SIGINT signals
1858 are received. Affected file silcd/silcd.c.
1860 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1862 * Simple handling of TERM and HUP signals. Also added some log
1863 flushing call around. Affected file is
1866 * Fixed small bugs in silclog.c. Now buffering output will take
1867 effect after 10 seconds since startup: This will ensure that
1868 no important startup messages are lost. Also output redirection
1869 will preserve original format ([Date] [Type] message).
1870 Affected file is lib/silcutil/silclog.c.
1872 * Added two options to the config file, in the logging section:
1873 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1874 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1876 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1878 * Do not print the warning about log files not being initialized
1879 more than once to avoid excess logging. Affected file is
1880 lib/silcutil/silclog.c.
1882 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1883 the SIM copying in make install in Makefile.am.pre.
1885 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1887 * Rewritten silclog APIs. Globally interesting changes follows:
1888 silc_log_set_files() changed to silc_log_set_file().
1889 silc_log_set_callbacks() changed to silc_log_set_callback().
1890 ROBOdoc documented silclog header file.
1891 SilcLogCb now returns bool to wether inihibit the default
1892 handler or not (to keep the old behaviour return always TRUE).
1893 The new APIs should also fix the problem of the
1894 silcd_error.log file that was written in the current directory.
1897 Log files streams will remain opened after silc_log_set_file()
1898 call, means less CPU usage notably on high traffic servers.
1899 File streams are now full buffered, and flushed to the disk
1900 every 5 minutes, lesses HD activity and CPU usage.
1901 Messages can be redirected, allowing admins to configure
1902 one single logfile for all server messages.
1903 the silc_log_quick global variable to activate fast-logging.
1904 Affected files lib/silcutil/silclog.[ch]
1906 * Changed some code to conform new silclog APIs. Affected
1907 files are doc/example_silcd.conf.in, silcd/server.c
1908 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1911 * Fixed a memory leak that could occur in some situations.
1912 Affected file silcd/serverconfig.c.
1914 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1916 * Added the silc_client_del_client to remove the client from
1917 all channels as well. Affected file lib/silcclient/idlist.c.
1919 * Fixed the client library to correctly remove the client
1920 from all channels when the client entry is being destroyed.
1921 Affected file lib/silcclient/client_notify.c, command.c.
1923 * Added auto-nicking support to the client library. If the
1924 applicatio now sets client->nickname it will be sent to the
1925 server after connecting by the library. This way for example
1926 SILCNICK (or IRCNICK) environment variables will have effect
1927 and always change the nickname automatically to whatever
1928 it is wanted. Affected file lib/silcclient/client.[ch].
1930 * Renamed silc_server_command_bad_chars to the
1931 silc_server_name_bad_chars and moved it to the
1932 silcd/server_util.[ch]. Added also new function
1933 silc_server_name_modify_bad to return nickname that
1934 includes bad characters as new nickname without those
1935 bad characters. This check and modify is now used in
1936 silc_server_new_client when the username is initially set
1937 as nickname, so it must be checked to be valid nickname.
1938 Affected file silcd/packet_receive.c.
1940 * The nickname length is now taken from the packet for real
1941 and not trusted to strlen() since it clearly can return
1942 wrong length for nickname including bad characters. This
1943 also applies to channel names. Affected file silcd/command.c.
1945 * Removed the lib/silcsilm/modules directory. Modules are now
1946 compiled into the lib/silcsim. Fixed the copying of the
1947 modules to follow symbolic links in Makefile.am.pre.
1949 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1951 * Fixed silc_string_regexify list creation. Fixes bugs with
1952 BAN and INVITE commands in server. The affected file is
1953 lib/silcutil/unix/silcunixutil.c.
1955 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1957 * Removed the command destructor entirely from the server's
1958 command and command reply routines. It is not needed, and
1959 its usage was buggy and caused crashes. Affected files are
1960 silcd/command[_reply].[ch].
1962 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1964 * Cancel protocol and NULL sock->protocol if timeout
1965 occurred during protocol. Affected file silcd/server.c.
1967 * Cancel protocol timeouts always before calling the final
1968 callback, to assure that after final callback is called
1969 no other state will be called for the protocol anymore.
1970 Affected file silcd/protocol.c.
1972 * Print error log if incoming connection configuration could
1973 not be found. Affected file silcd/server.c.
1975 * Fixed JOIN command to correctly save the founder mode
1976 to the client on normal SILC server, when the channel
1977 was created by the router. Affected file silcd/command.c.
1979 * Fixed LIST command (hopefully) to send correct reply
1980 packets. Affected file silcd/command.c.
1982 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1984 * The silc_packet_receive_process now returns FALSE if the
1985 read data was invalid packet, and TRUE if it was ok.
1987 The server now checks that if unauthenticated connection
1988 sends data and its processing fails the server will close
1989 the connection since it could be a malicious flooder.
1991 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1993 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1995 * Make sure the warning about error opening a log file is
1996 printed only once and not everytime it fails (produces
1997 too much useless log). Affected file lib/silcutil/silclog.c.
1999 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2001 * Made the silc_server_daemonise() function more readable.
2002 Affected file silcd/server.c.
2004 * Pid file is now optional, the user may comment it out from
2005 the config file. Removed define SILC_SERVER_PID_FILE, we
2006 don't need a default any longer. Affected file
2007 configure.in.pre, lib/Makefile.am.pre.
2009 * Make some use of the pid file. The server now dies at startup
2010 if it detects a valid pid file on his path. The server would
2011 die anyway in this circumstance, because of the bind() failure.
2012 Affected file silcd/silcd.c.
2014 * No longer compiling lib/dotconf.
2016 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2018 * Fixed JOIN command parsing not to crash. Affected file
2019 lib/silcclient/command.c.
2021 * Fied the NICK_CHANGE notify to add the new client entry
2022 even it is resolved. This removes an <[unknown]> nick
2023 thingy bug in the client. Affected file is
2024 lib/silcclient/client_notify.c.
2026 * Do not try to allocate 0 bytes (efence does not like it)
2027 in lib/silccore/silccomand.c when encoding payload.
2029 * Do not take IRCNICK as nickname in Irssi SILC client since
2030 it is not possible to set nickname before hand connecting
2031 the server (TODO has an entry about adding auto-nicking
2034 * Changed the silc_server_command_pending to check whether
2035 there already exists an pending entry with the specified
2036 command, command identifier and pending callback. This is
2037 to fix IDENTIFY and WHOIS related crashes that may register
2038 multiple pending commands with same identifier. Affected
2039 file silcd/command.c.
2041 * Fixed the server to reconnect to the router even if it
2042 was already reconnecting and EOF was received. This to
2043 fix a possibility that the server wouldn't ever try to
2044 auto-reconnect to the router. Affected file silcd/server.c.
2046 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2048 * Fixed the server's password authentication to use the
2049 length of the locally saved password, and not the one
2050 sent in the packet. Affected file silcd/protocol.c.
2052 * Fixed same password authentication problem in the
2053 Authentication Payload handling routines in
2054 lib/silccore/silcauth.c.
2056 * Yet another password authentication problem fixed with
2057 channel password handling in silcd/command.c.
2059 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2061 * If first character of string in silc_parse_userfqdn is '@'
2062 then do not parse it. Affected file is
2063 lib/silcutil/silcutil.c.
2065 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2067 * Fixed minor bug in IDENTIFY command reply sending, which
2068 caused various weird problems during JOIN when it was
2069 resolving names for users. Affected file silcd/command.c.
2071 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2073 * Fixed the IDENTIFY command reply sending to chech better valid
2074 clients. It was possible to send incomplete list of replies.
2075 Affected file silcd/command.c.
2077 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2079 * Added silc_client_command[s]_[un]register functions now to
2080 dynamically register the commands in client library. Removed
2081 the static table of commands. This allows the client library
2082 to call commands without causing the application to know about
2083 what commands library has called.
2085 Removed the INFO command reply kludge to detect when the command
2086 was called by library. Now library use its own command reply
2087 function for INFO command.
2089 Added function silc_client_command_call to call a command.
2090 Application can use it to call command, not access the structure
2093 Now all commands that are sent by the client library (not
2094 explicitly sent by application) use own command reply functions.
2096 Affected files around lib/silcclient/ and in
2097 irssi/src/silc/core/.
2099 * Fixed the WHOIS command reply sending to chech better valid
2100 clients. It was possible to send incomplete list of replies.
2102 Fixed the WHOIS and IDENTIFY to send the request to router
2103 if normal server did not do it and did not find any results.
2105 Affected file silcd/command.c.
2107 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2109 * Moved the internal data from SilcClient context into its
2110 own file, not accesible to application. Affected files
2111 lib/silcclient/client.h and lib/silcclient/client_internal.h,
2112 and other files in client library.
2114 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2116 * Added doc/examples installation target in Makefile.am.pre.
2119 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2121 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
2122 commands the found client entry will be removed from the
2123 cache, after notifying application about the error. Affected
2124 file lib/silcclient/command_reply.c.
2126 * Changed the /MSG to check for exact nickname user gave, and
2127 not let `nick' match `nick@host' if it is only one found. Now,
2128 user must type the exact nickname (like nick@host2) even if
2129 there are no more than one same nicks found. This is to avoid
2130 a possibility of sending nickname to wrong nickname since
2131 `nick' could match `nick@host'. Affected file is
2132 irssi/src/core/silc-servers.c.
2134 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2136 * Do not print "you are now server operator" or similar when
2137 giving /away command. Affected files are
2138 irssi/src/silc/core/client_ops.c, silc-servers.h.
2140 * Made the silc_server_command_pending_error_check to send
2141 the same command reply payload it received back to the
2142 original sender of the command. This way all arguments
2143 that was received by the server will be received by the
2144 client too. Affected file silcd/command.c.
2146 * Added the silc_idcache_add to return the created cache entry
2147 to a pointer. Affected file lib/silccore/silcidcache.[ch].
2149 * Add global clients to expire if they are not on any channel.
2150 This is because normal server will never know if they signoff
2151 if they are not on any channel. The cache expiry will take
2152 case of these entries. This is done by normal servers only.
2153 The affected files are silcd/command_reply.c,
2154 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
2156 * If server receives invalid ID notification for WHOIS or
2157 IDENTIFY and the ID exists in the lists, it is removed.
2158 Affected file silcd/command_reply.c.
2160 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
2161 in client then client entry that it matches is searched and
2162 the nickname is printed on the screen for user. Affected
2163 file irssi/src/silc/core/client_ops.c.
2165 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2167 * Use cache entry expire time in the LIST command reply to
2168 purge old entries from the cache after the LIST command
2169 reply has been received. This way we don't have non-existent
2170 entries in the cache for too long. Affected file is
2171 silcd/command_reply.c.
2173 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2175 * If we are normal server, and we've not resolved client info
2176 in WHOIS or IDENTIFY from router, and it is global client,
2177 we'll check whether it is on some channel. If it is not
2178 then we cannot be sure about its validity and will resolve it
2179 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
2180 file silcd/command.c.
2182 * Search channel by name (if possible) rather than by ID
2183 in IDENTIFY command's command reply. Affected file is
2184 silcd/command_reply.c.
2186 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2188 * Distribute to the channel passphrase in CMODE_CHANGE notify.
2189 Updated specs and implemented it. Affected file silcd/command.c,
2190 silcd/packet_send.c and silcd/packet_receive.c.
2192 * Implemented the <founder auth> payload handling in the JOIN
2193 command. If provided all conditions for channel joining
2194 except requirement to provide correct passphrase can be
2195 overrided by the channel founder. Updated the protocol specs.
2196 Affected file silcd/command.c.
2198 Added support for founder auth in JOIN command in client
2199 library. Fixed the parsing of the JOIN command now to support
2200 all options as they should be. The affected file is
2201 lib/silcclient/command.c.
2203 * Optimized the WHOIS and IDENTIFY commands to send the request
2204 to router only if it includes nicknames or other names. If
2205 they include only IDs then check the local cache first before
2206 routing. Affected file is silcd/command.c.
2208 * Added channels topic announcements. Affected file is
2209 silcd/packet_receive.c and silcd/server.c.
2211 * Fixed the silc_server_send_notify_topic_set to really destine
2212 the packet to channel. Affected file silcd/packet_send.c.
2214 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
2215 library. Affected file lib/silcclient/client_notify.c.
2217 * Added UMODE announcements. Affected file silcd/server.c.
2219 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2221 * Memory leak fixes in:
2223 lib/silcutil/silcsockconn.c
2224 lib/silcske/silcske.c
2225 lib/silcske/groups.c
2227 lib/silccrypt/silcpkcs.c
2228 lib/silccore/silccommand.c
2229 lib/silccore/silcidcache.c
2234 * ROBOdoc documented the lib/silcske/groups.h file and a
2235 bit changed the interface for better.
2237 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2239 * Update the client entry context in the ID cache after
2240 nick change. Affected file lib/silcclient/command.c.
2241 Fixes the CUMODE command when regaining founder privileges,
2242 and a little WHOIS problem.
2244 * Fixed silc_net_gethostbyname to correctly call the
2245 inet_ntop. Affected file lib/silcutil/silcnet.c.
2247 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2249 * Added IPv6 support checking to the configure.in.pre, added
2250 also --enable-ipv6 option to override the check. Affected
2251 file configure.in.pre.
2253 * The silc_thread_create now calls the start function
2254 directly if threads support is not compiled in. Removes
2255 ugly #ifdef's from generic code. Affected files are
2256 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
2258 * Added silc_net_gethostby[name/addr]_async to asynchronously
2259 resolve. Affected files are lib/silcutil/silcnet.[ch].
2261 * Added support for rendering IPv6 based server, client and
2262 channel IDs. Affected file lib/silcutil/silcutil.c.
2264 * Added support for creating IPv6 based server IDs. Affected
2265 file is silcd/serverid.c.
2267 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2269 * Added silc_net_gethostby[addr/name] into the
2270 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
2271 routines. Added silc_net_is_ip[4/6]. Affected file is
2272 lib/silcutil/unix/silcunixnet.c. All routines that take
2273 address as argument now supports both IPv4 and IPv6 addresses.
2275 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2277 * Fixed LIST command reply sending in server. Affected file
2280 * Server now sends the kicker's client ID in the KICK notify
2281 to the kicked client. Affected file silcd/command.c.
2283 * The client library now parses the kickers client ID and
2284 UI displays it. Affected files lib/silcclient/client_notify.c
2285 and irssi/src/silc/core/silc-channels.c, module-formats.c.
2287 * Made all payload parsing function prototypes consistent.
2288 They all take now const unsigned char * and uint32 pair as
2289 the payload data instead of SilcBuffer. Changes all around
2290 the source tree. Other unsigned char* -> const unsigned char*
2291 changes around the tree as well.
2293 * Optimized SFTP client and server packet sending not to
2294 allocate new buffer for each packet but to recycle the
2295 first allocated buffer. Affected files are
2296 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
2298 * Optimized the SFTP client to use SilcList instead of
2299 SilcDList for requests, because it is faster. Affected file
2300 is lib/silcsftp/sftp_client.c.
2302 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
2303 into lib/silccore/silcid.[ch].
2305 Renamed silcpayload.[ch] into silcargument.[ch].
2307 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2309 * If client entry is deleted with active key agreement
2310 session, abort the session.
2312 The silc_client_abort_key_agreement now calls the completion
2313 callback with new SILC_KEY_AGREEMENT_ABORTED status.
2315 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
2318 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2320 * Don't use __restrict in older GCC's. Affected file is
2321 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
2323 * silc_net_localhost now attempts to reverse lookup the
2324 IP/hostname. Affected file lib/silcutil/silcnet.c.
2326 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
2327 command. It can be used to gain founder privileges at
2328 the same time when joining the channel.
2330 Defined that the SILC_NOTIFY_TYPE_KICKED send the
2331 kicker's client ID as well. Updated protocol specs.
2333 Defined that the server must send SILC_COMMAND_IDENTIFY
2334 command reply with error status to client who sent
2335 private message with invalid client ID.
2337 Updated the protocol specification.
2339 * Added silc_server_send_command_reply to send any
2340 command reply. Affected file silcd/packet_send.[ch].
2342 * Added silc_id_payload_encode_data to encode ID payload
2343 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
2345 * The server now send IDENTIFY command reply with error
2346 status if client ID in private message is invalid. Affected
2347 file silcd/packet_receive.c.
2349 * Save the server key file with server's IP address in
2350 the filename instead of hostname. The affected file is
2351 irssi/src/silc/core/client_ops.c.
2353 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2355 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
2358 * Added libtool support for compiling shared objects in
2359 lib/silcsim. Affected file configure.in.pre and
2360 lib/silcsim/Makefile.am. Original patch by cras.
2362 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2364 * Pid file configuration, and server's config file fixes
2365 patch by toma. Updated CREDITS file.
2367 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2369 * Fixed silc_client_channel_message to not try to decrypt
2370 the message twice if it resolved the destination client
2371 information. This could cause of dropping one channel
2372 message. Affected file lib/silcclient/client_channel.c.
2374 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2376 * Added silc_client_run_one into lib/silcclient/silcapi.h and
2377 lib/silcclient/client.c. This function is used when the SILC
2378 Client is run under some other scheduler, or event loop or
2379 main loop. On GUI applications, for example this may be
2380 desired to used to run the client under the GUI application's
2381 main loop. Typically the GUI application would register an
2382 idle task that calls this function multiple times in a second
2383 to quickly process the SILC specific data.
2385 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2387 * Fixed silc_server_drop() for dropping the supplementary
2388 groups as well, this could cause a security hole on some
2391 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2393 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
2396 * Write PID file after dropping privileges. Added -F option
2397 to run server on foreground. A patch by debolaz.
2398 Affected files silcd/server.c, silcd/silcd.c.
2400 * Fixed MOTD to return the MOTD file server name. Affected
2401 file silcd/command.c.
2403 * Added INFO command reply handling to the Irssi SILC Client.
2404 Affected file irssi/src/silc/core/client_ops.c.
2406 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2408 * Fixed the silc_idcache_list_* routines to really support
2409 the dynamic list. Fixes a crash. Affected file is
2410 lib/silccore/silcidcache.c.
2412 * Fixed the LIST command reply to really call LIST command's
2413 pending callbacks. Affected file silcd/command_reply.c.
2415 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2417 * Update conn->local_entry->nickname after giving NICK
2418 command. Affected file lib/silcclient/command.c.
2420 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
2422 * Added the [pid] option to the silcd configuration file
2424 Affected files: serverconfig.[ch] and silcd.c
2426 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2428 * Save fingerprint in WHOIS command reply in server.
2429 Affected file silcd/command_reply.c.
2431 * Fixed NICK commands pending callback registration.
2432 Affected file lib/silcclient/command.c.
2434 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2436 * Use ++server->cmd_ident when sending commands in server,
2437 instead of random number. Affected file silcd/command.c.
2439 * Fixed GETKEY command reply to call actually GETKEY pending
2440 command callbacks. Affected file silcd/command_reply.c.
2442 * A bit stricter check for nicknames. Check for same nickname
2443 in NICK command also. Affected file silcd/command.c.
2445 * Do not call INFO command everytime client ID changes, only
2446 during first connecting. Affected file lib/silcclient/client.c.
2448 * Set the new nickname only after successful command reply for
2449 NICK command is returned by server. Affected file
2450 lib/silcclient/command.c.
2452 * Remove nicknames from nicklist during server_signoff notify.
2453 Should fix /NAMES bit more. The affected file is
2454 irssi/src/silc/core/silc-channels.c.
2456 * Added `fingerprint' field to the SilcIDListData in the
2457 silcd/idlist.h to hold the fingerprint of the client's
2460 Send the fingerprint of the client's public key in WHOIS
2463 Affected files silcd/command.c, and silcd/idlist.[ch].
2465 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
2466 create fingerprint from given data.
2468 * Show the fingerprint of the client's public key in WHOIS.
2469 Affected files irssi/src/module-formats.[ch] and
2470 irssi/src/silc/core/client_ops.c.
2472 * Format the multiple same nicknames also during JOIN and
2473 NICK_CHANGE notifys. Affected file is
2474 lib/silcclient/client_notify.c.
2476 * Do not print error on screen for invalid private message
2477 payload since it can come if someone is sending private
2478 messages with wrong key. Affected file
2479 lib/silccore/silcprivate.c.
2481 * Fixed multiple concurrent /PING crash. Affected file
2482 lib/silcclient/command.c.
2484 * Changed the wrong ID encoding. All IP addresses must be
2485 in MSB first order in encoded format. They were encoded
2486 wrong and was in LSB format. Affected files are
2487 silcd/serverid.c, lib/silcutil/silcutil.c.
2489 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
2491 * Call the `connect' client operation through the scheduler
2492 in case of error. Affected file lib/silcclient/client.c.
2494 * Call the `failure' client operation even if the error
2495 occurred locally during a protocol. Affected file is
2496 lib/silcclient/protocol.c.
2498 * Added support of sending LIST command to router from normal
2499 server. This way normal server can get list of all channels
2500 in the network too. Fixed the channel list sending in the
2501 server too. Affected files are silcd/command.c, and
2502 silcd/command_reply.[ch].
2504 * Added silc_server_update_channels_by_server and
2505 silc_server_remove_channels_by_server. They are used during
2506 disconnection of primary router and in backup router protocol.
2507 Affected file silcd/server_util.[ch], silcd/server.c and
2508 silcd/server_backup.c.
2510 * Fixed channel adding to global list in IDENTIFY command
2511 reply in server. Affected file silcd/command_reply.c.
2513 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2515 * If the incoming packet type is REKEY or REKEY_DONE process
2516 that packet always synchronously. Fixes yet another MAC
2517 failed error on slow (dialup) connections. Affected file
2518 lib/silcclient/client.c and silcd/server.c.
2520 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2522 * Call check_version SKE callback for initiator too. Affected
2523 file lib/silcske/silcske.c.
2525 * Implemented fix for security hole found in the SKE that was
2526 fixed in the specification few days back; the initiator's
2527 public key is now added to the HASH value computation.
2528 Added backwards support for the old way of doing it too, for
2529 old clients and old servers. Affected file is
2530 lib/silcske/silcske.c.
2532 * Enabled mutual authentication by default in SKE. If initiator
2533 is not providing mutual authentication the responder will
2534 force it. This will provide the proof of posession of the
2535 private key for responder. The affected files are
2536 lib/silcclient/protocol.c and silcd/protocol.c.
2538 * Do not cache anymore the server's public key during SKE.
2539 We do mutual authentication so the proof of posession of
2540 private key is done, and if the server is authenticated in
2541 conn auth protocol with public key we must have the public
2542 key already. Affected file silcd/protocol.c.
2544 * Added new global debug variable: silc_debug_hexdump. If
2545 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
2546 file lib/silcutil/silclog.[ch].
2548 * Fixed compilation warning due to char * -> const char *.
2549 Affected files lib/silcutil/silcnet.h, and
2550 lib/silccore/silcauth.[ch].
2552 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2554 * Fixed CMODE command when new channel key was created. If
2555 the creation failed the old key was removed. Next time giving
2556 same command would crash the server since the old key was
2557 freed already. Affected file silcd/command.c.
2559 * Fixed the silc_server_announce_get_channels to not crash
2560 on reconnect. Affected file silcd/server.c.
2562 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2564 * Added silc_log_set_debug_string function to set a regex
2565 string to match for debug output. Only the function names,
2566 or filenames matching the given debug string is actually
2567 printed. This way it is possible to filter out those debug
2568 strings that user is not interested in.
2570 Fixed a bug in silc_string_regexify.
2572 Affected files lib/silcutil/silclog.[ch], and
2573 lib/silcutil/unix/silcunixutil.c.
2575 * Changed the -d options in both server and Irssi SILC client
2576 to take the debug string as argument. Affected files
2577 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
2579 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2581 * Added silc_hash_babbleprint to create a Bubble Babble
2582 Encoded fingerprint. The encoding is developed by Antti
2583 Huima (draft-huima-babble-01.txt), and it creates human
2584 readable strings out of binary data. Affected file
2585 lib/silccrypt/silchash.[ch].
2587 * Print the babble print now in addition of fingerprint as well
2588 in Irssi SILC client. Affected files are
2589 irssi/src/fe-common/silc/module-formats.[ch],
2590 irssi/src/fe-common/silc/core/client_ops.c.
2592 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2594 * Fixed a security problem found in SKE. The initiator's
2595 public key too is now added to the HASH hash value creation
2596 which is signed by the responder to create the SIGN value.
2597 This will prevent anyone in the middle to lie to the responder
2598 about the initiator's public key. If this is done now, the
2599 man in the middle will get caught. Updated the protocol
2602 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2604 * Better installation directory handling. Configure module
2605 paths and other paths automatically to example_silc* files
2606 in doc/. A patch by toma.
2608 * Fixed compiler warning from MPI library, and from SILC RNG.
2611 * Added SILC_SERVER_PID_FILE to define the pid file for server.
2612 It can be configured with ./configure. A patch by toma.
2614 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>

2636 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2638 * Added silc_pkcs_public_key_compare to compare two
2639 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
2641 * Check that the client who set the founder mode on the
2642 channel is the same client that is giving the founder
2643 mode to itself. It is done by comparing the saved public
2644 key (it is saved even in the authentication is passphrase).

2652 * Process the DISCONNECT packet through scheduler in the
2653 client library. Affected file lib/silcclient/client.c.
2655 * Fixed the silc_client_packet_parse to not to increase
2656 the packet sequence number if the conn->sock and the
2657 current socket connection is not same. This can happen
2658 for example during key agreement when the conn includes
2659 multiple socket connections (listeners). Affected file
2660 lib/silcclient/client.c.
2662 * The sender of the file transfer request now provides also
2663 the pointer (listener) for the key exchange protocol. If
2664 the listener cannot be created then it sends empty key
2665 agreement and lets the receiver provide the listener.
2667 Added `local_ip' and `local_port' arguments to the
2668 silc_client_file_send. If they are provided they are used,
2669 if not then it will attempt to find local IP address, if
2670 not found or bind fails then the remote client will provide
2673 Affected files are lib/silcclient/client_ftp.c and
2674 lib/silcclient/silcapi.h.
2676 * Extended the FILE SEND command to support defining the
2677 local IP and port for key exchange listener. They are

2682 * Defined to WHOIS command reply the sending of fingerprint
2683 of the client's public key (if the proof of posession of the
2684 corresponding private key is verified by the server).
2685 Updated to the protocol specification.
2687 * Added support of receiving the client's public key's
2688 fingerprint in command reply in client library. Affected
2689 file is lib/silcclient/command_reply.c, and
2690 lib/silcclient/idlist.[ch].
2692 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>

2749 preserve the WHOWAS info for the client. Affected file
2750 silcd/server_util.c.
2752 * Fixed SERVER_SIGNOFF notify handling in the server. The
2753 server is now able to process incoming SERVER_SIGNOFF notify
2754 for a server that it doesn't even know about. It will remove
2755 the clients provided in the notify. Affected file
2756 silcd/packet_receive.c.
2758 * Check for partial packet in data queue after every packet that
2759 was found from the queue. Return and wait for more data if
2760 there is partial data in queue. Affected file is
2761 lib/silccore/silcpacket.c.
2763 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>

2778 irssi/src/fe-common/silc/module-formats.[ch].
2780 * Wrote a help file for FILE command.
2782 * Added silc_rng_global_get_byte_fast to get not-so-secure
2783 random data as fast as possible. Random data is read from
2784 /dev/urandom if available and from the SILC RNG if not
2785 available. It is used in padding generation. Affected file
2786 lib/silccrypt/silcrng.[ch].
2788 * All packets in client library are now processed synchronously.
2789 Optimized packet processing a lot. Affected file
2790 lib/silcclient/client.c.
2792 * All server connection packets are processing synchronously
2793 now in server, to optimize packet processing. Affected file
2796 * Include files are installed now only in Toolkit distribution
2797 if make install is given. Affected files: all Makefile.am's.

2801 * Assure that silc_client_notify_by_server_resolve does not
2802 resolve the client information multiple times. If it cannot
2803 be found by the first it cannot be found at all. Affected
2804 file lib/silcclient/client_notify.c.
2806 * Fixed WHOWAS command reply calling. Affected file
2807 lib/silcclient/command_reply.c.
2809 * Removed all references to silc_idlist_get_client from the
2810 Irssi SILC client since that call is internal call used by
2811 the library. The Irssi SILC client will use now client
2812 retrieval functions found in silcapi.h.
2814 * Fixed a bug in resolving nickname info before sending
2815 private message. It used freed memory. Affected file
2816 irssi/src/silc/core/silc-servers.c.

2837 * Added silc_net_localip to return local host's IP address.
2838 Affected file lib/silcutil/silcnet.[ch].
2840 * If key exchange or rekey protocol is active for a connection
2841 parse all packets syncronously since there might be packets
2842 in packet queue that we are not able to process without first
2843 processing packets before them. Affected file silcd/server,
2844 lib/silcclient/client.c.
2846 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2847 whether library should continue processing the packet.
2848 Affected file lib/silccore/silcpacket.h.

2898 Make sure also that USERS command reply does not resolve
2899 twice information. Affected file is
2900 lib/silcclient/command_reply.c.
2902 Make sure that silc_client_get_clients_by_list does not
2903 resolve twice same information.
2905 * Check for valid client->id in the silc_server_free_client_data.
2906 Affected file silcd/server.c.
2908 * Fixed /GETKEY nick@server not to crash if the server entry

2921 * Call the silc_server_udpate_servers_by_server in the
2922 primary router that comes back online in the backup resuming
2923 protocol. Otherwise it routes packets wrong. Affected file
2924 silcd/server_util.[ch], silcd/server_backup.c.
2926 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2928 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2929 lib/silcutil/silcbuffmt.[ch].
2931 * Redefined the SILC packet header to include the padding
2932 length. Affected file lib/silccore/silcpacket.[ch].
2934 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2935 length for maximum padding up to 128 bytes). Affected
2936 file lib/silccore/silcpacket.h.
2938 * Removed all backwards support for old 0.5.x MAC thingies.
2939 The SILC packet header change makes it impossible to be
2940 backwards compatible.
2942 * Send the ENDING packet with timeout in the backup resuming
2943 protocol. This is to assure that all routers has connected
2944 to the primary router. Affected file silcd/server_backup.c.
2946 * Changed the RNG to take the first IV from random data. It
2947 used to take it from zero actually. Changed the RNG also
2948 to use /dev/urandom during session. /dev/random is used
2949 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2951 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

2954 (the packet length) encrypted. Affected files aroung the
2955 code tree, lib/silccore/silcpacket.[ch]. Removed the
2956 SilcPacketCheckDecrypt callback. It is not needed anymore
2957 since the silc_packet_receive_process will determine now
2958 whether the packet is normal or special.
2960 * Implemented the unidirectional MAC keys. Affected files
2961 lib/silcske/silcske.c, silcd/protocol.c and

2969 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2971 * Allow backup router to announce servers. All servers
2972 announced by backup router are added to the global list
2973 automatically. Update hte server's socket to our primary
2974 router also when backup router announces a server.
2975 Affected file silcd/packet_receive.c.
2977 * Do not update the client->router in the function
2978 silc_server_udpate_clients_by_server if the client is on
2979 global list. We might fail to find any specific server
2980 for locally connected clients and local cell clients. They
2981 should still use the `from' and not `to' as client->router.
2982 This fixes backup router resuming protocol. Affected file
2983 silcd/server_util.c.
2985 * Decrease channel statistics count only if the channel
2986 deletion worked. Affected files are silcd/server.c and
2987 silcd/server_util.c.
2989 * Added silc_server_update_servers_by_server to update origin
2990 of all server entries. Used during backup router protocol.

3007 to the router it came from. Affected file is
3008 silcd/packet_send.c. Fixed memory leak too.
3010 * Announce informations for incoming router connection, but
3011 only after checking if it is replaced by backup router.
3012 Affected file silcd/packet_receive.c.

3021 silcd/packet_send.c.
3023 * Fixed silc_server_send_notify_dest to set the broadcast
3024 flag. Fixed the silc_server_send_notify_topic to actually
3025 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
3026 Affected file silcd/packet_send.c.
3028 * Changed the SFTP Filesystem interface. Changed the
3029 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
3030 the filesystem operation function. The SilcSFTPFilesystem
3031 is now a context that is allocated by all filesystem allocation
3032 functions and it already includes the operations structure
3033 and filesystem specific context. It is given as argument
3034 now to the silc_sftp_server_start. This made the interface
3035 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
3036 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
3038 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3040 * Changed the backup router adding and getting interfaces
3041 in the server. The router that will be replaced by the

3103 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
3104 in the server to indicate disabled entry. All data read
3105 from the connection will be ignored and no data is sent
3106 for entry that is disabled. Affected files are
3107 silcd/idlist.h, silcd/server.c.

3136 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
3137 Affected file lib/silcutil/silcbuffer.h.
3139 * Changed various routines in the core library to use the new
3140 silc_buffer_set instead of allocating new buffer only for
3143 * Added 64-bit value formatting and unformatting support to the
3144 silc_buffer_[un]format routines. Affected file is
3145 lib/silcutil/silcbuffmt.[ch].
3147 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
3148 to includes/bitmove.h.
3150 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3152 * Fixed channel user mode saving in client library. Affected
3153 file lib/silcclient/command[_reply].c.
3155 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3157 * Defined the file transfer to the SILC Protocol. Added
3158 new packet type SILC_PACKET_FTP and defined File Transfer
3159 Payload. The mandatory file transfer protocol is SFTP
3160 (SSH File Transfer Protocol). Affected file in addition
3161 of the internet draft is lib/silccore/silcpacket.h.
3163 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
3164 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
3165 is used as part of backup router protocol when the primary
3166 router of the cell is back online and wishes to resume
3167 the position as primary router.
3169 * Redefined the MAC generation keys in the protocol. The
3170 same key is not used anymore in both direction. Both
3171 direction will now use different keys for sending and
3172 receiving. This fixes a potential security flaw. This
3173 change causes incompatibilities in the protocol.
3175 * Redefined also the MAC computation from the packet.
3176 An packet sequence number is now added to the MAC
3177 computation. This prevents possible replay attacks against
3178 the protocol. This change too causes incompatibilities
3181 Added `sequence' field to the SilcPacketContext to hold
3182 the current sequence number for the packet.
3184 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3186 * Added `created' field to the SilcIDListData in the file
3187 silcd/idlist.h to indicate the time when the entry was
3190 * Added `created' field to the SilcChannelEntry too. Affected
3191 file silcd/idlist.h.
3193 * Added `creation_time' aguments to all the announcement functions
3194 in the server. If it is provided then only the entries that
3195 was created after the provided time frame are actually
3196 announced. Affected file silcd/server.[ch].
3198 * The protocol says that the Channel ID's IP address must be
3199 based on the router's IP address. Added check for this in
3200 the silc_server_new_channel when processing incoming New Channel
3201 Payload. Affected file silcd/packet_receive.c.
3203 * Print out the correct version with --version in SILC client.
3204 Affected file irssi/src/silc/core/silc-core.c.
3206 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3208 * Fixed WHOWAS command to check for completnes of the client
3209 entry always, not just when the command is coming from client.
3210 Affected file silcd/command.c.
3212 * Added new function silc_server_packet_queue_purge to purge the
3213 outgoing data queue to the network. After the function returns
3214 it is guaranteed that the outgoing packet queue is empty.
3215 Affected file silcd/packet_send.[ch].
3217 * Purge the outgoing packet queue in the rekey protocol's final
3218 callback to assure that all rekey packets go to the network
3219 before quitting the protocol. Affected file silcd/server.c.
3221 * Added silc_client_packet_queue_parse as similar function as
3222 in server to the client library. The affected file is
3223 lib/silcclient/client.c.
3225 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3227 * Splitted silcd/server.c and created silcd/server_util.[ch]
3228 for utility functions.
3230 * Added new socket flag SILC_SF_DISABLED to indicate that the
3231 connection is open but nothing can be sent to or received from
3232 the connection. Affected file lib/silcutil/silsockconn.[ch].
3233 The checking for disabled socket is checked in the low level
3234 silc_socket_write and silc_socket_read functions.
3236 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3238 * Allow only nicknames and channel names that fits into the
3239 7-bit unsigned char ASCII set. Affected file silcd/command.c.
3241 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3243 * When processing JOIN command reply in server check that if
3244 the channel exists in our global list we'll move it the local
3245 list. Affected file silcd/command_reply.c.
3247 * Fixed the check whether client is joined on the channel already
3248 in JOIN command. Affected file lib/silcclient/command.c.
3250 * Fixed the JOIN command reply to check whether the channel
3251 already exists. Affected file lib/silcclient/command_reply.c.
3253 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3255 * Added silc_ske_status_string to map the SKE error numbers
3256 to readable strings. The affected files are
3257 lib/silcske/silcske[_status].[ch].
3259 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3261 * Do not show the private channels on the WHOIS channel list
3262 as it is not allowed by the protocol. The affected file is
3265 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3267 * Assure that the packet length digged from the actual packet
3268 is something sensible in the silc_packet_decrypt_rest_special
3269 in lib/silccrypt/silcpacket.c.
3271 * Free and NULL the allocated pointer in silc_hmac_alloc if
3272 the HMAC allocation fails. The affected file is
3273 lib/silccrypt/silchmac.c.
3275 * Print the selected security properties to the log files in
3276 the server. Affected file silcd/protocol.c.
3278 * Add SKE's reference counter even if calling the completion
3279 callback manually. Otherwise it goes negative, although it
3280 does not cause any problems. The affected file is
3281 lib/silcske/silcske.c.
3283 * Remove the client entry with short timeout after giving the
3284 KILL command. Affected file lib/silcclient/command.c.
3286 * Fixed to send error reply in WHOIS and IDENTIFY commands in
3287 case all found clients are already disconnected (WHOWAS would
3288 found them) in the server. Affected file silcd/command.c.
3290 * Update the last_receive (time of last data received) to be
3291 updated only when received private or channel message so that
3292 the idle time showed in WHOIS makes more sense.
3294 * Added boolean field `valid' in to the SilcClientEntry in the
3295 client library to indicate whether the entry is valid or not.
3296 This fixes the nickname change bug on channel when changing
3297 the nickname to be same than the old (like nick to Nick) the
3298 nickname formatter doesn't set the new nick anymore to Nick@host.
3299 Affected file lib/silcclient/idlist.[ch].
3301 * Now actually fixed the nickname changing on disconnection.
3302 Added new function silc_change_nick to the Irssi SILC Client.
3303 Affected file irssi/src/silc/core/client_ops.c,
3304 irssi/src/silc/core/silc-nicklist.[ch].
3306 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3308 * Check that the public key exists in the GETKEY command before
3309 trying to encode it. Affected file silcd/command.c.
3311 * Print some notifications on received public keys with GETKEY
3312 command in the Irssi SILC Client. Affected files are
3313 irssi/src/fe-common/silc/module-formats.[ch],
3314 irssi/src/silc/core/client_ops.c.
3316 * Use IDENTIFY command to resolve the server information in the
3317 GETKEY command instead of INFO command. Affected file
3318 lib/silcclient/command.c.
3320 * All command reply functions in the client library now calls
3321 the pending command reply callbacks even if an error has
3322 occurred. The server has done this a long time and now it was
3323 time to move the client library to this as well. Now all
3324 errors can be delivered back to the pending command reply
3325 callbacks if necessary. Affected files are
3326 lib/silcclient/command[_reply].[ch].
3328 * Change the nickname on disconnection back to the username
3329 because in reconnect the server will enforce it to it anyway.
3330 Affected file irssi/src/silc/core/silc-servers.c.
3332 * Fixed a config file parsing bug in the Irssi SILC client.
3333 Affected file irssi/src/silc/core/clientconfig.c.
3335 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3337 * When printing the channel mode on JOIN, verify that the
3338 channel key and channel's HMAC are valid. Affected file
3339 irssi/src/silc/core/client_ops.c.
3341 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3343 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
3344 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
3345 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
3347 * Removed channel key rekey task deleting from the function
3348 silc_server_save_channel_key. Affected file silcd/server.c.
3349 Added explicit timeout task context instead that is used to
3350 delete the task if we are registering a new task before the
3351 new task has elapsed.
3353 * When channel key rekey occurs the client library now saves
3354 the old channel key for a short period of time (10 seconds) and
3355 is able to use it in case some is still sending channel
3356 messages encrypted with the old key after the rekey. Affected
3357 file lib/silcclient/[idlist.h|client_channel.c].
3359 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3361 * Added check to the silc_server_new_id_real to not accept
3362 new ID if it is the sender's own ID. Affected file is
3363 silcd/packet_receive.c.
3365 * Assure that we do not announce ourself or the one we've
3366 sending our announcements when we're router and are announcing
3367 servers to our primary router. Affected file silcd/server.c.
3369 * Fixed silc_server_command_identify_check_client to assemble
3370 correct WHOIS packet. It send corrupted WHOIS packet and
3371 caused problem with router to router connections. Affected
3372 file silcd/command.c.
3374 Fixed also silc_server_command_whois_check the same way
3375 as for the IDENTIFY command.
3377 * Added new SilcIDListStatus to the server in the SilcIDListData
3378 structure. The status now includes the current status of
3379 the entry (like registered, resolved etc.). Affected file
3380 silcd/idlist.[ch]. Defined a bunch of different status types
3381 as well. This replaced the old boolean registered field as well.
3383 Added resolve_cmd_ident field to the SilcClientEntry structure
3384 too so that if the entry is for example being resolved so
3385 another command may attach to the same pending command reply
3386 without requiring to resolve the same entry again. This concept
3387 should optimize the WHOIS and the IDENTIFY resolving under
3388 heavy load by taking away unnecessary resolving for entries
3389 that are being resolved already.
3391 Added support for adding multiple pending commands for one
3392 command idenfier. Affected file silcd/command[_reply].[ch].
3394 * Fixed WHOIS and IDENTIFY save to remove the cache entry
3395 before deleting the data. Otherwise the hash table will have
3396 freed data in comparison functions. Affected file is
3397 silcd/command_reply.c.
3399 * Fixed silc_idlist_replace_client_id to add the new entry to
3400 the cache with NULL nickname. Otherwise there will be invalid
3401 memory as the nickname after the nickname is freed. Affected
3402 file silcd/packet_receive.c.
3404 * Fixed the silc_idlist_get_clients_by_hash. The entries was
3405 saved into wrong slots because the previous number of entries
3406 was not taken into account. Affected file silcd/idlist.c.
3407 Fixed same thing in silc_idlist_get_clients_by_nickname too.
3409 * If we are router and we receive JOIN notify to a channel that
3410 does not have any users then notified client is marked as the
3411 channel founder, as it is it. The affected file is
3412 silcd/packet_receive.c
3414 * Added to the extended hash table API's table_del_*ext functions
3415 the destructor as argument too, so that the caller can decide
3416 which destructor to use or whether to use destructor at all.
3417 Affected file lib/silcutil/silchashtable.[ch].
3419 * Fixed ID Cache purging. It actually deleted the entries from
3420 the hash table after the data was freed. The hash table ended
3421 up comparing freed memory. The affected file is
3422 lib/silccore/silcidcache.c.
3424 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3426 * Fixed Irssi SILC client's KILL command's HELP syntax.
3428 * The USERS command now resolves the detailed user information
3429 if the userinfo field is missing. Affected file is
3430 lib/silcclient/command_reply.c.
3432 * Do not print error in silc_file_read if the read file does
3433 not exist. Just silently return NULL. Affected file is
3434 lib/silcutil/silcutil.c.
3436 * Fixed the silc_log_output to not wine about NULL filename
3437 and to not create some bogus " " filename. Affected file is
3438 lib/silcutil/silclog.c.
3440 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3442 * Fixed various printing bugs on the user interface in the
3443 Irssi SILC Client. Minor changes that were forgotten from
3446 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3448 * Fixed the configure.in.pre and the compilation and distribution
3449 environment to support the new autoconf 2.52. That version is
3450 now required to compile the CVS trunk.
3452 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3454 * Renamed function silc_parse_nickname to silc_parse_userfqdn
3455 to generally parse user@fqdn format strings. Affected file
3456 lib/silcutil/silcutil.c.
3458 * Added nickname_format and nickname_force_format fields to the
3459 SilcClientParams structure. The first one defines the format
3460 for the nicknames that the library will enforce if the receives
3461 multiple same nicknames. The second one is boolean value and
3462 can be used to force the library to always enforce the format
3463 to the nicknames regardles whether there are multiple nicknames
3464 or not. This configurable formatting was employed to flexibly
3465 support accessing multiple nicknames from the user interface.
3466 The userinterface can now set the nicknames to what ever format
3467 they prefer. Affected file lib/silcclient/silcapi.h.
3469 Added function silc_client_nickname_format to the file
3470 lib/silcclient/idlist.c. It performs the nickname formatting.
3472 Added new field `hostname´ to the SilcClientEntry context.
3473 It holds the hostname of the client. Affected file is
3474 lib/silcclient/idlist.h.
3476 * Irssi SILC Client sets the nicknames in nick@hostn format.
3477 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
3478 irssi/src/silc/core/silc-core.c.
3480 The WHOIS printing now also shows both the real nickname and
3481 the formatted nickname so that user knows how to access the
3482 user if there are multiple same nicknames cached. Affected
3483 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
3484 printing formatting too to take the hostname now as a separate
3485 argument. The Affected file is
3486 irssi/src/fe-common/silc/modules-formats.[ch].
3488 * Changed the silc_client_get_clients_local to accept the formatted
3489 nickname as argument. It accepts the real nickname too but the
3490 formatted nickname can be used to find the true entry from
3491 multiple entries. Affected file lib/silcclient/silcapi.h and
3492 lib/silcclient/idlist.c.
3494 * Added nickname_format_parse field to the SilcClientParams.
3495 It is a callback function provided by the application to parse
3496 the nickname out of the formatted nickname string. The library
3497 calls it to get the nickname from the formatted string. Since
3498 the application generally knows better the format of the nickname
3499 string it parses it instead of the library, even though library
3500 encodes the formatted string. If the callback function is not
3501 provided then the library will use the string as is. The
3502 affected file is lib/silcclient/silcapi.h.
3504 * All the nickname strings passed to the client library in
3505 commands are now expected to be formatted nickname strings.
3506 If the command does not support the formatted nickname string
3507 it will assume that the sent string is the actual nickname.
3508 Affected file lib/silcclient/command.c.
3510 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3512 * Added public key authentication support to OPER and SILCOPER
3513 commands in the client library. Affected file is
3514 lib/silcclient/command.c.
3516 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3518 * Changed the get_auth_methdod client operation to be asynchronous.
3519 It can be async if the application resolves the authentication
3520 method from the server during the negotiation. Added new
3521 SilcGetAuthMeth completion callback that the application will
3522 call after resolving the authentication method.
3524 Added function silc_client_request_authentication_method that
3525 the application can use to resolve the authentication method
3526 from the server. Added also SilcConnectionAuthRequest callback
3527 that the library will call after the server has replied. The
3528 application can call this function if it does not know the
3529 current authentication method.
3531 Affected files are lib/silcclient/client.c and
3532 lib/silcclient/silcapi.h.
3534 * The Irssi SILC client now automatically resolves the authentication
3535 method incase any configuration information is not present (and
3536 currently there never is). The affected file is
3537 irssi/src/silc/core/client_ops.c.
3539 * Fixed public key authentication from the client library.
3540 Affected file lib/silcclient/protocol.c. Changed also the
3541 protocol specification about the public key authentication in
3542 the connection authentication protocol. The actual data to be
3543 signed is now computed with a hash function before signing.
3545 * Fixed the public key authentication from the server as well.
3546 Affected file silcd/protocol.c.
3548 * Removed the mlock()'s from the memory allocation routines.
3549 Affected file lib/silcutil/silcmemory.c. The ./configure does
3550 not check anymore for the mlock(). Affected file is
3553 * Fixed USERS command in server to allow the execution of the
3554 command for private and secret channels if the client sending
3555 the command is on the channel. Affected file silcd/command.c.
3557 * Fixed silc_client_get_clients_local to return the clients
3558 count correctly. It could return wrong value. Affected file
3559 lib/silcclient/idlist.c.
3561 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3563 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
3564 types. The assembler optimizations seemed not to like 64-bit
3565 data types. The assmebler optimizations thus are now enabled
3566 also for BSD systems as opposed to only enable them for Linux.
3568 * Do not check for threads at all on BSD systems. Affected
3569 file configure.in.pre.
3571 * Removed -n and -h options from the Irssi SILC Client since
3572 they are not used in silc.
3574 * Fixed the prime generation to assure that the first digit
3575 of the generated random number is not zero since our conversion
3576 routines does not like number strings that starts with zero
3577 digit. If zero digit is seen the random number is regenerated.
3578 This caused some corrupted RSA keys when the zero first digit
3579 was met. Affected file lib/silcmath/silcprimegen.c.
3581 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3583 * Fixed WIN32 configuration in the ./configure script.
3584 Fixed to include xti.h on environments that has it.
3585 Patches by Carsten Ilchmann and andrew.
3587 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3589 * Changed the silc_id_create_client_id to be collision
3590 resistant. It is now assured that there cannot be created
3591 two same client ID's. I suspect that some weird bugs in
3592 the server were actually caused by duplicate Client IDs.
3593 Affected file silcd/serverid.[ch]. A router receiving
3594 new ID now also assures and informs the sending server
3595 if the ID caused collision.
3597 * Changed the silc_id_create_channel_id to also assure that
3598 there are no collisions.
3600 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3602 * Statement about ignoring the Mutual Authentication flag when
3603 performing rekey with PFS was a bit misleading. It is ignored
3604 if it was set in the initial negotiation, it cannot be even
3605 set in the rekey. Fixed in the ke-auth draft. Started the
3606 new versions of the protocol drafts in the doc/.
3608 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3610 * Fixed a bug in silc_client_command_identify_save when saving
3611 new channel information. The channel name was no duplicated
3612 and caused crash on exit. Affected file is
3613 lib/silcclient/command_reply.c.
3615 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3617 * Fixed the getkey command handling in the server. Send just
3618 empty OK reply to the sender if the key could not be fetched
3619 (but everything else was ok, like the key just was not available).
3620 Changed the public key parameter to optional in the protocol
3621 specs so that empty OK reply can be sent. Affected file
3624 Added a message to Irssi SILC client to tell to user if the
3625 server did not return a public key.
3627 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3629 * Fixed a channel key regeneration bug. It registered new
3630 timeout tasks exponentially until all system resources were
3631 used. Affected file silcd/server.c.
3633 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3635 * Added the SILC Document generator to the scripts/silcdoc.
3636 It can be used to generate the Toolkit Reference Manual out
3637 of the source tree. Internally it will also use the RoboDoc
3638 generator now imported in util/robodoc.
3640 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3642 * Added couple of return's in rekey protocol if error orccurred
3643 during the protocol. The execution must be terminated.
3644 Affected file silcd/protocol.c. Also, terminate the protocol
3645 always with timeout.
3647 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3649 * The client's Client ID was created initally from the wrong
3650 nickname (it could have been in format nick@host) in the
3651 silc_server_new_client. Affected file silcd/packet_receive.c
3653 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3655 * Added some SILC_LOG_ERROR's to various error conditions
3656 if client could not be added to ID cache. Affected files
3657 silcd/packet_receive.c and silcd/server.c.
3659 * When client's sock->user_data is freed, NULL also the
3660 client->router and client->connection pointers. Added check
3661 for these pointers being NULL to various places around the
3662 code. Affected file silcd/server.c.
3664 * Added client->data.registered == TRUE checks to various
3665 places around the code to assure that unregistered client's
3666 are not handled when it is not allowed. Affected file
3669 * Added `bool registered' fields to all
3670 silc_idlist_[server|client]_get_* routines to indicate whether
3671 the fetched client needs to be registered or not. Affected
3672 file silcd/idlist.[ch].
3674 * Add your own entry as registered to the ID cache in the
3675 server. Affected file server.c.
3677 * Fixed a bug in silc_server_new_server. The SilcServer was
3678 set as the new server's context instead of SilcServerEntry.
3679 This naturally caused some weird bugs.
3681 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3683 * Do not delete the channel rekey task when adding it
3684 for in silc_server_create_channel_key.
3686 * Changed the silc_server_create_channel_key to return
3687 TRUE or FALSE to indicate the success of the channel key
3690 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3692 * Fixed MSVC++ project files and added missing files to

3698 does not have it defined. Affected files are
3699 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3701 * Fixed buffer overflow from Irssi SILC Client. Affected
3702 file irssi/src/fe-common/core/themes.c.
3704 * Fixed double free in client library in the file
3705 lib/silcclient/client.c when disconnecting from server.
3707 * Applied double free patch from cras to Irssi SILC client.
3708 Affected files irssi/src/core/[modules/expandos].c
3710 * Fixed the disconnection handling to Irssi SILC Client.
3711 The application must call silc_client_close_connection
3712 in ops->connect client operation in case of failure of
3713 the connection. Affected file is
3714 irssi/src/silc/core/client_ops.c.
3716 * Do not set sock->protocol to NULL in the function
3717 silc_client_close_connection after executing the protocol's
3718 final callback since the sock might not be valid anymore.
3719 Affected file lib/silcclient/client.c.
3721 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3723 * Do not enable SILC_THREADS if the linking with libpthread
3724 did not happen. Affected file configure.in.pre.
3726 * Added notion to protocol specification that server must
3727 verify the sent authentication payload with CMODE when
3728 setting the channel founder key. Implemented it to the
3729 server. Affected file silcd/command.c.
3731 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3733 * Added _EXTRA_DIST SILC distribution variable to the
3734 distributions file. It is used to conditionally add extra
3735 files or directories to the specific distribution. Affected
3736 files ./prepare, Makefile.am.pre and distributions.
3738 Removed the `_' from the start of the distribution names.
3741 * Added README.WIN32 for instructions to compile the Toolkit
3744 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3746 * Fixed a double free in disconnection in the server. Affected
3747 file is silcd/server.c.
3749 * Fixed the lib/silcske/groups.c to work now also with GMP
3750 MP library. The string conversion did not work when using
3751 specific base and the base is indicated in the string as well.
3753 * Created win32/ directory which now includes MSVC++ specific
3754 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3755 It will appear only in the toolkit distribution
3757 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3759 * Changed the key material distribution function in case when
3760 the hash output is too short. The data is now concatenated
3761 a bit differently than it used to. Made the change to the
3762 SKE protocol specification.
3764 * Added better GMP detection to configure.in.pre. A patch
3767 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3769 * Fixed a minor bug in SKE that might cause some problem on
3770 some platforms. Affected file lib/silcske/silcske.c.
3772 * Added the cookie checking for initiator in the SKE. It checks
3773 that the responder returns the sent cookie unmodified. The
3774 affected file is lib/silcske/silcske.c. Added new SKE
3775 error type INVALID_COOKIE that can be sent during the
3776 negotiation. Fixed some memory leaks as well.
3778 * Added the "invalid cookie" error message to Irssi SILC client's
3781 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3783 * Added `task_max' field to the SilcClientParams to indicate
3784 the maximum tasks the scheduler can handle. If set to zero,
3785 default values are used. Affected file lib/silcclient/silcapi.h.
3787 * Fixed memory leaks in silc_client_close_connection. Affected
3788 file lib/silcclient/client.c.
3790 * Added silc_client_del_client_entry to client library to free
3791 all memory of given client entry. Affected file is
3792 lib/silcclient/idlist.[ch].
3794 * Added new functions silc_client_del_channel and
3795 silc_client_del_server to delete channel and server entries.
3796 Affected file lib/silcclient/[silcapi.h/idlist.c].
3798 * Removed silc_client_del_client_by_id from silcapi.h.
3800 * Fixed the INFO command to return the server's own info
3801 correctly when querying by Server ID. Affected file is
3804 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3806 * Removed the non-blocking settings in WIN32 code in the
3807 silc_sock_[read/write] and added SleepEx instead. Affected
3808 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3809 of input data is now checked with FIONREAD and ioctlsocket.
3811 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3813 * Call silc_schedule_task_del_by_context in the
3814 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3815 Affected file lib/silccore/silcprotocol.c.
3817 * Call silc_protocol_cancel for active protocols in the
3818 silc_server_close_connection if the funtion
3819 silc_server_free_sock_user_data has not been called.
3820 Affected file silcd/server.c.
3822 * Generic tasks cannot be deleted using the del_by_fd
3823 task deleting function since generic tasks does not match
3824 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3826 * Added a notion to SILCOPER help file that the SILCOPER works
3827 only on router server, not on normal server.
3829 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3831 * Added for WIN32 support for the new scheduler as well.
3832 Affected file lib/silcutil/win32/silcwin32schedule.c.
3834 * Fixed the SHA1 implementation to work on various platforms.
3836 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3838 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3839 API. It is part of the scheduler now. Everything else is
3840 as previously but some functions has changed their names.
3841 Checkout the lib/silcutil/silcschedule.h for the interface.
3842 Updated all applications to use the new interface. Affected
3843 files are lib/silcutil/silcschedule.[ch].
3845 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3847 * Found a bug in the SKE implementation. The HASH value,
3848 specified by the protocol, was not computed correctly. The
3849 public key of the responder was not added to the computation
3850 even though it is mandatory. Affected file lib/silcske/silcske.c.
3851 This unfortunately causes incompatibilities with older
3852 clients and servers.
3854 * Added WIN32 specific network init and uninit functions:
3855 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3856 the Winsock2. Affected file lib/silcutil/silcnet.h and
3857 lib/silcutil/win32/silcwin32net.c.
3859 * Set the socket always to nonblocking mode on WIN32 after
3860 reading data or writing data. Affected file is
3861 lib/silcutil/win32/silcwin32sockconn.c.
3863 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3865 * Fixed various compilation problems under WIN32. Affected
3866 files lib/silcutil/win32/silcwin32thread.c and
3867 lib/silcutil/win32/silcwin32schedule.c.
3869 * Removed all _internal.h #includes from public header
3870 files. Internal headers must never be included from
3873 Removed also the lib/silcske/payload_internal.h file.
3875 * All include files that may be needed (public and some others
3876 included by the public headers) by application developers are
3877 now copied to the ./includes directory. It does not copy any
3878 internal headers. Affected file Makefile.defines.pre and all
3879 Makefile.am's under lib/ and subdirs.
3881 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3883 * Do not change the ~/.silc directory's permissions automatically.
3884 Affected file irssi/src/silc/core/clientutil.c.
3886 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3888 * Do not cancel the protocol in silc_server_close_connection
3889 it might cause recursion. Now cancelled in the function
3890 silc_server_free_sock_user_data. Affected file silcd/server.c.
3892 * Fixed the silc_server_remove_clients_by_server to regenerate
3893 the channel keys correctly finally. Added also new function
3894 silc_server_remove_clients_channels to actually do it.
3895 Affected file silcd/server.c.
3897 * Fixed the silc_server_new_channel to not crash by giving
3898 wrong router to the new channel. Affected file is
3899 silcd/packet_receive.c.
3901 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3903 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3904 which is given as argument to the silc_client_alloc now.
3905 It can be used to configure the client and set various parameters
3906 that affect the function of the client.
3908 * The USERS command in server did not check whether the channel
3909 is private or secret. Affected file silcd/command.c.
3911 * Added new argument to the USERS command in protocol specification.
3912 The USERS command now can take the channel name as argument
3913 as well. Added support for this in client and server and
3914 updated the protocol specs.
3916 * Completed the GETKEY command in client. It can be now used
3917 to fetch also servers public key not only some clients.
3918 Affected files lib/silcclient/command[_reply].c.
3920 * Added silc_client_get_server to return server entry by the
3921 server name. Affected files lib/silcclient/silcapi.h and
3924 * Redefined the IDENTIFY command in protocol specification to be
3925 more generic. It now can be used to query information about
3926 any entity in the SILC Network, including clients, servers and
3927 channels. The query may be based either the entity's name
3928 or the ID. Added support for this in both client and server.
3930 Affected files silcd/command.c and lib/silcclient/command.c
3931 and command_reply.c.
3933 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3934 the _from_client and _from_server functions. Affected file
3937 * Added silc_client_get_channel_by_id_resolve to the file
3938 lib/silcclient/silcapi.h to resolve channel information by
3939 its ID. Added also silc_client_get_channel_by_id that
3940 does not resolve it from the server.
3942 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3944 * Added SilcServerEntry context into the client library
3945 to represent one server. The INFO command now allocates
3946 these to save the resolved server info. For now on the
3947 client library will also keep information about servers,
3948 connected and resolved with INFO.
3950 The INFO command now allocates the SilcServerEntry context
3951 and saves the server info there. The COMMAND_REPLY in
3952 the INFO now returns the parameters to application in
3953 same order as defined in the protocol specification.
3955 The entries are cached in the client->server_cache.
3957 * The INFO command is now issued after received the Client ID
3958 from the server. Affected file lib/silcclient/client.c.
3960 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3961 to the application as the mode changer might be server.
3962 It is guaranteed that NULL is not returned anymore to the
3963 application. Affected file lib/silcclient/client_notify.c.
3965 The ID Type is now also passed to the application so that
3966 it can check whether the returned entry is SilcClientEntry
3969 Added new function silc_client_get_server_by_id to return
3970 the server entry by ID. Affected files are the
3971 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3973 * Do not create the channel in the Irssi SILC Client when issuing
3974 the JOIN command but when received the sucessful JOIN command
3975 reply. Otherwise the channel might get created even though we
3976 could not join it. The Affected file is
3977 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3979 * Fixed a channel joining bug in router. The router must also
3980 check the channel modes, invite and ban lists etc. when serving
3981 the JOIN command sent by normal server. Affected file is
3982 silcd/command.c. The router now resolves the client's
3983 information from the server who sent the JOIN command if it
3984 does not know it, and processes the JOIN command only after
3987 * Changed the SilcCommandCb to take new argument; void *context2.
3988 Affected file lib/silccore/silccommand.h
3990 The second argument in the command callbacks in the server now
3991 includes the SilcServerCommandReplyContext if the command was
3992 called as pending command callback from the command reply.
3993 Otherwise it is NULL. When called as pending the status of the
3994 command reply will be checked and if it was erronous the
3995 error will be sent to the original sender of the command.
3996 This way the client always receives the error messages even
3997 though the server was actually the one who received the error
3998 when it resent the command to router, for example. Affected
3999 files silcd/command[_reply].[ch].
4001 * Fixed sending WHOWAS command's error message to client if
4002 the requested client could not be found. It was missing.
4005 * Changed the CMODE and CUMODE commands reply arguments in the
4006 protocol specification. The Channel ID is now sent in both
4007 of the commands to identify the channel. Implemented this
4008 new feature to the client and server. Affected files
4009 lib/silcclient/command_reply.c and silcd/command.c.
4011 * Made better checks for invite and ban lists in the JOIN
4012 command in server. Affected file silcd/command.c.
4014 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4016 * The server now performs the incoming host IP/DNS lookup
4017 using the silc_socket_host_lookup and thus does not block
4018 the server anymore. Affected file silcd/server.c.
4020 * Completed the multi-thread support for SILC Scheduler in
4021 the lib/silcutil/silcschedule.c.
4023 * Fixed the configure.in.pre to detect the pthread correctly
4026 * Fixed a deadlock in silc_task_queue_wakeup in the file
4027 lib/silcutil/silctask.c.
4029 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4031 * Added new function silc_schedule_wakeup that is used in
4032 multi-threaded environment to wakeup the main thread's
4033 schduler. It needs to be used when a thread adds a new task
4034 or removes a task from task queues. After waking up, the
4035 scheduler will detect the task queue changes. If threads
4036 support is not compiled in this function has no effect.
4037 Implemented the wakeup mechanism to both Unix and WIN32
4038 systems. Affected files are lib/silcutil/silcschedule.[ch],
4039 lib/silcutil/unix/silcunixschedule.c and the
4040 lib/silcutil/win32/silcwin32schedule.c.
4042 * Added new function silc_task_queue_wakeup to wakeup the
4043 scheduler by the specified task queue. Affected file
4044 lib/silcutil/silctask.[ch].
4046 * The silc_socket_host_lookup_start now wakes up the scheduler
4047 after adding the timeout task. Affected file is
4048 lib/silcutil/silcsockconn.c.
4050 * The silc_socket_host_lookup is synchronous now if the threads
4051 support is not compiled in. However, the callback is still
4052 called asyncronously through the scheduler, anyway. Affected
4053 file lib/silcutil/silcsockconn.c.
4055 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4057 * Added new function silc_socket_host_lookup to perform
4058 asynchronous IP and FQDN lookups for the socket connection.
4059 Affected files lib/silcutil/silcsockconn.[ch].
4061 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4063 * Added SILC_MUTEX_DEFINE to define the mutex on environments
4064 that may or may not compile the mutex support in.
4066 Changed the silc_mutex_alloc interface. It allocates the
4067 mutex now to the sent pointer and returns TRUE or FALSE.
4069 Affected file lib/silcutil/silcmutex.h.
4071 * Wrote the SILC Task Queue interface to support multi-threads.
4072 Affected file lib/silcutil/silctask.[ch].
4074 * Wrote the SILC Scheduler to support multi-threads. Affected
4075 file lib/silcutil/silcschedule.c.
4077 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4079 * Implemented the SILC Mutex API and SILC Thread API for WIN32
4080 in lib/silcutil/win32/.
4082 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4084 * Defined SILC Mutex API and SILC Thread API and implemented
4085 them for Unix. Affected files are
4086 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
4087 lib/silcutil/unix/silcunixmutex.c and
4088 lib/silcutil/unix/silcunixthread.c.
4090 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4092 * Fixed the silc_server_remove_clients_by_server's channel
4093 key re-generation. The hash table handling was incorrect
4094 and would not work with many channels. Affected file is
4097 * Fixed some memory leaks around the server code.
4099 * Rewrote the silc_server_get_users_on_channel to support IPv6
4100 based Client ID's. Affected file silcd/server.c.
4102 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
4103 specification. However, a separate document must be written
4104 to define the detailed signing procedure and the payload
4105 associated with the flag. Defined the flag to the
4106 lib/silccore/silcchannel.h as well.
4108 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4110 * Changed the dynamic tables to static size tables in the
4111 lib/silccrypt/silchmac.c.
4113 * Removed GCC dependencies from the code. A patch by cras.
4115 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4117 * Do not show the error "Error receiving packet bla bla"
4118 in server if it really was not an error (-2 means that reading
4119 is pending). Affected file silcd/server.c.
4121 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4123 * Fixed a possible crash in silc_server_remove_clients_by_server
4124 in silcd/server.c. Fixed there also some memory leaks.
4126 * Fixed the silc_idlist_replace_client_id. It could replace
4127 wrong key in the hash table. Affected file silcd/idlist.c.
4129 * Do not check whether there are global users on the channel
4130 if the channel->global_users is FALSE. Affected functions
4131 silc_server_remove_from_one_channel and
4132 silc_server_remove_from_channels in silcd/server.c. Also,
4133 do not check if the removed client is local as we can be
4134 sure that global client was not removed from the channel
4135 and checking for global users is not needed.
4137 * The silc_server_remove_clients_by_server now re-generates
4138 the channel keys correctly for those channels that had
4139 clients removed from them. Affected file silcd/server.c.
4141 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4143 * Found the reason of random crashes in the server. We weren't
4144 ignoring the SIGPIPE signal (which can be sent in write())
4145 and it crashed the server. Affected file silcd/silcd.c.
4147 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4149 * Assure that sock->user_data is not NULL in the function
4150 silc_server_packet_send in silcd/packet_send.c.
4152 * Disconnect the remote connection if it could not be added
4153 to any ID lists in the server. The affected file is
4156 * Check in silc_server_packet_send[_real/dest] that the
4157 socket is not disconnecting and ignore the data if it is.
4158 Affected file silcd/packet_send.c.
4160 * Define inline to __inline on native WIN32 compilation.
4161 Affected file includes/silcwin32.h.
4163 * Added some explicit type casts for inline code since MSVC
4164 require them. Affected files lib/silcutil/silcbuffer.h,
4165 lib/trq/silcdlist.h and lib/trq/silclist.h.
4167 * Print warning in log files from now on if the packet
4168 decryption fails. Affected file silcd/server.c.
4170 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4172 * Changed the `say' client operation's interface to accept
4173 new `type' argument to indicate the type of the message sent
4174 by the library. The application may filter the library's
4175 messages according the type. The affected file is the
4176 lib/silcclient/silcapi.h.
4178 * Added two new functions to lib/silcclient/silcapi.h:
4179 silc_client_del_client and silc_client_del_client_by_id.
4180 Affected file lib/silcclient/idlist.c.
4182 * Moved the clientincludes.h from includes/ to silc/ and
4183 serverincludes.h from includes/ to silcd/.
4185 * The modes for the CMODE and CUMODE are now passed as
4186 uint32 for application with COMMAND_REPLY. The affected
4187 file is lib/silcclient/command_reply.c.
4189 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4191 * /WHOIS without arguments shows client's own information.
4192 Affected file lib/silcclient/command.c.
4194 * Changed PING to not accept any arguments. The specs
4195 says that client can ping only the connected server so
4196 requiring an argument is not needed. Affected file is
4197 lib/silcclient/command.c.
4199 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4201 * Fixed a fatal bug in private message sending and reception
4202 encryption and decryption when using private message keys.
4203 The implementation was incorrect and did not follow the
4204 specification. It causd that some of the message were
4205 lost since it did not use the sending and receiving keys
4206 as the protocol suggests. This has been fixed and will cause
4207 incompatibilities with older clients when sending private
4208 message encrypted with private message keys. Affected files
4209 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
4210 and various other in Irssi SILC Client.
4212 Added `responder' boolean argument to the functions
4213 silc_client_add_private_message_key[_ske] to indicate when
4214 the key is added as responder or initiator of the key
4217 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4219 * Removed the silc_ske_check_version function and created
4220 a SilcSKECheckVersion callback. Added also a function
4221 silc_ske_set_callbacks that is now used to set all SKE
4222 callbacks. The callback functions are not given to
4223 the SKE functions anymore, but this function is used to
4226 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
4228 * Added `silc_version' argument to the silc_client_alloc
4229 to define the version of the application for the library.
4230 The library will use the version string to compare it
4231 against the remote host's (usually a server) version
4232 string. Affected file lib/silcclient/silcapi.h
4234 * Added the KE protocol context to Key Agreement context
4235 in client library so that we can abort the SKE if it
4236 is in process when we get timeout. Affected file is
4237 lib/silcclient/client_keyagr.c.
4239 * Do not resolve the client ID forever if it returns in the
4240 first time that such client does not exist. This was done
4241 for example with private message. Affected file is
4242 lib/silcclient/client_prvmsg.c.
4244 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4246 * Do not add regex.h for WIN32. The affected file
4247 includes/silcincludes.h.
4249 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
4250 not work yet 100%. It generates the DLL's automatically
4251 when compiling with --with-win32 under cygwin.
4253 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4255 * lib/contrib/regex.c is not compiled on WIN32.
4257 * Added silc_net_get_socket_opt function to the
4258 lib/silcutil/silcnet.h.
4260 * Added includes/silcwin32.h for WIN32 specific includes
4263 * Do not use ptime structure or any of the posix process
4264 functions on WIN32 in lib/silccrypt/silrng.c.
4266 * Added silc_gettimeofday to provide generic function
4267 for struct timeval on all platforms. Added the function
4268 to lib/silcutil/silcutil.h.
4270 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4272 * Moved the lib/silccore/silcsockconn.[ch] to the utility
4273 library as they clearly belong there. As a plus side we
4274 can make the actual socket connection routines platform
4277 Added also new generic function silc_socket_read and
4278 silc_socket_write (that used to be silc_packet_[read/write].
4279 The implementation of these are platform specific.
4281 * Added WIN32 specific routines of silc_socket_[read/write]
4282 to lib/silcutil/win32/silcwin32sockconn.c.
4284 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4286 * Added preliminary support for native WIN32 compilation under
4287 cygwin (using the -mno-cygwin option for GCC) to the
4288 ./configure.in.pre. The --with-win32 now prepares the
4289 compilation for native WIN32.
4291 * Rewrote the SILC Scheduler interface in the file
4292 lib/silcutil/silcschedule.h. The scheduler is now context
4293 based and does not have anymore any global static scheduler.
4294 Moved the Unix scheduler to the lib/silcutil/unix/ directory
4295 and created lib/silcutil/win32 directory for WIN32 based
4298 * Added Unix specific network routines to the
4299 lib/silcutil/unix/silcunixnet.c and the old
4300 lib/silcutil/silcnet.c includes now only generic routines.
4302 Added WIN32 specific network routines to the
4303 lib/silcutil/win32/silcwin32net.c.
4305 * Added Unix specific utility functions from the
4306 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
4308 * Added WIN32 SILC Scheduler to the file
4309 lib/silcutil/win32/silcwin32schedule.c. The code is of course
4312 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4314 * Do not handle JOIN notify in the server if the target client
4315 is not registered (idata->registered == FALSE). The affected
4316 file is silcd/packet_receive.c.
4318 * Update the nickrec->founder in event_cumode in the Irssi SILC
4319 client. Affected file irssi/src/silc/core/silc-channels.c.
4321 * Fixed the CUMODE_CHANGE notify handling in the server when
4322 server and router are announcing their clients on channels.
4323 Now the mode changes are saved and notified correctly. The
4324 affected file is /silcd/packet_receive.c.
4326 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
4327 They really did not replace the cache entry in the ID Cache.
4328 Now they do that. Affected file silcd/idlist.c.
4330 * Fixed the KICK notify handling in the Irssi SILC client to
4331 update the channel records so that the kicked client does not
4332 appear to be on the channel. The affected file is
4333 irssi/src/silc/core/silc-channels.c.
4335 * Always update the conn->current_channel when executing command
4336 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
4338 * Fixed the KILL notify handling in Irssi SILC client to remove
4339 the killed client on all channels.
4341 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4343 * Fixed the silc_parse_command_line to remove extra spaces
4344 from the start and end of the arguments. Affected file is
4345 lib/silcutil/silcutil.c.
4347 * Cancel and free any active protocol in the function
4348 silc_server_close_connection. Affected file silcd/server.c.
4350 * Cancel and free any active protocol in the function
4351 silc_client_close_connction. Affected file is
4352 lib/silcclient/client.c.
4354 * Do not execute the KILL command for clients that are in
4355 history (ie. they are not in the network). Affected file is
4358 * Fixed KILL notify handling, client does not crash anymore.
4359 Affected file irssi/src/silc/core/silc-channels.c.
4361 * Reduced the default packet buffer size from 2048 to 1024 in
4362 lib/silccore/silcpacket.c.
4364 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
4365 counter to the SKE context that is incresed when the SKE library
4366 performs async operation outside the library. If the outside
4367 process frees the SKE context and FREED status will be set
4368 and the library will detect after the sync operation that the
4369 libary is freed. The affected files are
4370 lib/silcske/silcske[_status].[ch].
4372 * Resolve the client entry information in the function
4373 silc_client_channel_message to assure that NULL pointer is not
4374 passed as client entry to the application. */
4376 * Fixed the task timeout calculation to assure that there is
4377 never negative timeouts. The affected file is
4378 lib/silcutil/silcschedule.c.
4380 * Fixed the channel user mode notification sending in server.
4381 It was sent point-to-point to the router (or to server by router)
4382 but it needs to be destined to a channel. The routines now
4383 supports sending the channel user mode notifys to the channels
4384 when announcing clients and channels. Affected files are
4385 silcd/server.c and silcd/packet_receive.c.
4387 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
4388 It did not actually replace the old channel entry in the cache.
4389 Affected file lib/silcclient/client_notify.c.
4391 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4393 * Fixed a possible crash in silc_packet_send_prepare. It now
4394 assures always that there is enough space in the buffer and
4395 at the tail area of the buffer (for MAC).
4397 Fixed the inbound buffer reallocation in silc_packet_read.
4398 It was old code and did not handle the reallocation correctly.
4401 The affected file is lib/silccore/silcpacket.c.
4403 * Fixed buffer overflow in silc_parse_nickname in the file
4404 lib/silcutil/silcutil.c.
4406 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4408 * make install generates new server keys only if there is not
4411 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4413 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
4414 Added check that if the NOREPLY is set then we will not send
4415 the away message. This avoids infinite loop of away messages
4416 if both clients are away. The affected file is
4417 lib/silcclient/client_prvmsg.c.
4419 * Fixed client crash if /NICK was given without arguments.
4420 Affected file lib/silcclient/command.c.
4422 * Server does not send the invite list in INVITE command back
4423 to the client if the list was not altered. Added this notion
4424 to the protocol spec as well. Affected file silcd/command.c.
4426 Fixed possible crash in INVITE command by checking the
4427 value of silc_server_get_client_route command.
4429 * Fixed the INVITE notify type handling. The arguments are now
4430 taken in correct order and client does not crash. The affected
4431 file is irssi/src/silc/core/silc-channels.c.
4433 Removed the "Inviting xxx to channel" message from the
4434 client library away and let the application handle it.
4435 Affected file lib/silcclient/command.c. Added that message
4436 to Irssi SILC client's message formats.
4438 * Fixed CMODE command crash in client. It now checks the
4439 amount of arguments correctly and does not crash. The affected
4440 file is lib/silcclient/command.c.
4442 * Do not create new channel automatically in silc_channels_join
4443 but check whether the channel by that name already exists.
4444 Affected file irssi/silc/core/silc-channels.c.
4446 * Do not send the SERVER_SIGNOFF to router if the disconnected
4447 entity was the router. Affected file silcd/server.c.
4449 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
4450 SILC client as it was missing from there.
4452 Added the handling of the KICK notify to the Irssi SILC client
4453 as it was missing. Added "you have been kicked" message to
4454 Irssi SILC client's message modules formats.
4456 Added the handing of the KILL notify to the Irssi SILC client
4457 as it was missing. Added the kill message module formats
4460 The affected file is irssi/src/silc/core/silc-channels.c.
4462 * The router did not save the channel mode the server announced.
4463 Affected file silcd/packet_receive.c.
4465 * Fixed a possible crash in INFO command in server. If the
4466 server did not provide the server info it crashed. Affected
4467 file silcd/command.c.
4469 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4471 * Fixed the GETKEY command in the server to check also the
4472 global list. Otherwise the GETKEY would not work correctly
4473 in normal SILC server. Affected file silcd/command.c.
4475 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4477 * Fixed GETKEY crash, it crashed if the command did not succseed.
4479 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4481 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
4482 is now real and not just an macro interface to GMP.
4484 Removed the entire GMP from the source tree and imported new
4485 NSS MPI library instead. Reason for removing GMP is that it is
4486 extremely large and compiles extremely slow. The NSS MPI
4487 is only a few files and compiles in less than 10 seconds.
4488 The speed is also about the same as GMP. The MPI is imported
4489 to lib/silcmath/mpi.
4491 If the system has GMP installed we will still use the GMP.
4492 If it is not then the NSS MPI will be compiled.
4494 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4496 * Merged a long nickname (127 characters long) crash bugfix from
4497 Irssi CVS tree. Affected file irssi/src/core/misc.c.
4499 * Merged a freed memory reference bugfix from Irssi CVS tree.
4500 Affected file irssi/src/core/commands.c.
4502 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4504 * Added the server's public key sving and verification to the
4505 server when performing the SKE. This was missing and the
4506 remote server's (or router's) public key was accepted without
4507 checking whether we have it previously or trust it at all.
4508 Affected file silcd/protocol.c.
4510 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4512 * Check in the silc_server_timeout_remote if protocol is active
4513 and make sure that the protocol's final callback is called so
4514 that all memory if freed. Affected file silcd/server.c.
4516 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4518 * silc_server_whois_send_reply crashed the server if the nickname
4519 was 127 characters long. Affected file silcd/command.c.
4521 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4523 * Added sanity check to the silc_server_new_client. If the hostname
4524 is provided inside username then check that the provided hostname
4525 really is the same as the resolved one. If the hostname was not
4526 resolved then check it from the public key. Affected file is
4527 silcd/packet_receive.c.
4529 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
4530 if the server disconnected us and the connection is not valid
4531 anymore. Affected file irssi/src/silc/core/silc-channels.c.
4533 * Moved the silc_client_[chmode|chumode|chumode_char] away from
4534 the library to the lib/silcutil/silcutil.[ch].
4536 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4538 * Close log file after open. Affected file
4539 lib/silcutil/silclog.c.
4541 * Check whether sock == NULL in silc_client_send_packet and return
4542 if it is. Affected file lib/silcclient/silcclient.c.
4544 * Check rec->entry == NULL in the Irssi SILC Client before
4545 sending the channel message. Affecte file is
4546 irssi/src/silc/core/silc-servers.c.
4548 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4550 * Merged a splitted window bugfix from Irssi CVS tree. The
4551 affected file is irssi/src/fe-text/textbuffer-view.c.
4553 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
4554 It did not print nickname.
4556 * Improved the distributions system a bit.
4558 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4560 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
4561 irssi/src/fe-text/gui-window.c.
4563 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
4564 to in-active server. The affected file is
4565 irssi/src/silc/core/client_ops.c.
4567 * Resolve the client in USERS command reply if the entry does
4568 not have username resolved. The affected file is
4569 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
4570 command to WHOIS command to really resolve stuff. The USERS
4571 is not used any more in any critical section so WHOIS can
4572 be used even though it might be slower than IDENTIFY.
4574 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
4577 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4579 * Changed the protocol API a bit more consistent in the
4580 lib/silccore/silcprotocol.[ch].
4582 * Changed the following headers to ROBODoc format:
4584 lib/silccore/silcpayload.h
4585 lib/silccore/silcprotocol.h
4586 lib/silccore/silcsockconn.h
4588 All core library headers are now formatted.
4590 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4592 * Fixed a bug in Irssi SILC client; do not show that you are
4593 server/router operator if you really are not. Affected file is
4594 irssi/src/silc/core/client_ops.c.
4596 * Renamed silc_command_free_payload to silc_command_payload_free.
4597 Affected file lib/silccore/silccommand.h
4599 * Added silcmath.h to include the prototoypes of various routines
4600 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
4603 * Changed the following headers to ROBODoc format:
4605 lib/silccore/silcchannel.h
4606 lib/silccore/silccommand.h
4607 lib/silccore/silcid.h
4608 lib/silccore/silcidcache.h
4609 lib/silccore/silcmode.h
4610 lib/silccore/silcnotify.h
4611 lib/silccore/silcpacket.h
4612 lib/silcmath/silcmath.h
4614 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4616 * Added checking to the server code not to start the server if
4617 ciphers and stuff are not configured properly. Affected files
4618 silcd/serverconfig.[h] and silcd/server.c.
4620 * Changed the layout of the header files of the public interfaces
4621 in the SILC libraries. The new layout supports ROBODoc
4622 documentation tool (and some others) so that it is easy to create
4623 a library reference manual. All the other headers and source
4624 code must still follow the CodingStyle document. Also source
4625 code must not include these ROBODoc stuffs, only the headers.
4626 Furthermore, all public interface headers must now be named
4627 by using `silc' prefix, example: silcapi.h, silccipher.h.
4628 Some files were renamed due to this. All the other headers
4629 must not be used as public interfaces. I will update the
4630 CodingStyle document later. Changed following headers, so far:
4632 lib/silcclient/silcapi.h
4633 lib/silccore/silcauth.h
4634 lib/silccore/silcprivate.h
4635 lib/silccrypt/silcdh.h
4637 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4641 * Removed silc_client_packet_send_flush from the client library
4642 as it is not needed. Affected file lib/silcclient/client.[ch].
4644 * Added printing of message of unresolved authentication method
4645 to the Irssi SILC client. Added it to the module formats.
4646 Removed the same message from the client library.
4648 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4650 * Added new distribution feature, DISTLABEL. Every distribution
4651 can define own preprocessor label that can be used in the
4652 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
4653 file distributions, acconfig.h.pre and prepare.
4655 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4657 * Added Makefile.defines_int to include the actual definitions
4658 for Makefile.defines.in. Tested the new distribution system,
4659 created distributions and tested installation.
4661 * Added AWAY message printing to the Irssi SILC client. Added
4662 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
4664 * Added SCONNECT command to call the SILC's CONNECT command.
4665 Cannot use CONNECT directly since Irssi uses that internally.
4666 Affected file irssi/src/silc/core/silc-servers.c.
4668 Added ACTION local command. It is same as ME command but takes
4669 the channel as mandatory argument.
4671 Rewrote some of the Irssi's help files to suite for SILC
4674 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4676 * Added Makefile.defines[.in] that should for now on be included
4677 in all Makefile.am file in the source tree. That file includes
4678 all common compilation definitions for SILC source tree.
4680 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4682 * Minor changes to the ./prepare script to change the package
4683 name according the distribution name to the configure.in.
4685 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4687 * Created new distribution system. Added file `distributions'
4688 that defines all the distributions that can be created out of
4689 the SILC source tree. The ./prepare script now reads that
4690 file to determine how to prepare the distributions. The
4691 first argument to the ./prepare is the name of the distribution
4692 and second is the version of the distribution. If given
4693 without arguments it creates the default (toolkit) distribution
4694 with the default version (defined in ./prepare).
4696 All Makefile.am files that are subject to the distributions
4697 are now named as Makefile.am.pre. These are ./Makefile.am
4698 and lib/Makefile.am. Others may be changed later.
4700 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4702 * Added invite list, ban list, some key management and connection
4703 error message printing to module formats in the Irssi SILC client.
4705 * Added new silc_client_set_away_message to set the away message
4706 that is back to the person who sent private message. The
4707 affected file lib/silcclient/silcapi.h and the
4708 lib/silcclient/client_prvmsg.c.
4710 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4712 * Fixed the private message sending in the Irssi SILC client,
4713 added local command KEY to the Irssi SILC client.
4715 Added key management and key agreement message formats to the
4716 irssi/src/fe-common/silc/module-formats.[ch].
4718 Added USERS (alias WHO) printing, server/router operator
4719 indication and LIST command printing to the module formats.
4721 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4723 * Fixed channel joining notify handling, cumode notify handling
4724 from Irssi SILC client.
4726 * Added SILC specific module-formats to the Irssi SILC client so
4727 that SILC specific message hilighting, colors etc is possible.
4728 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4730 Added channel mode, channel user mode, actions, notices,
4731 whois and whowas printing to the the module-formats.c.
4733 * Fixed a bug in channel deletion in the server. The channel
4734 is not left to the cache even if the channel founder auth mode
4735 is set when there are no users anymore on the channel. Affected
4736 file silcd/server.c.
4738 * The silc_net_localhost now resolves the entire hostname including
4739 the domain name. Affected file lib/silcutil/silcnet.c.
4741 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4743 * Changed the ask_passphrase client operation to be ascynchronous.
4744 It has now a completion callback and a context that the
4745 application must call after it has got the passphrase from
4746 the user. Affected files lib/silcclient/silcapi.h,
4747 lib/silcclient/protocol.c, lib/silcclient/command.c and
4750 Added SilcAskPassphrase callback that the application calls
4751 to deliver the passphrase to the library.
4753 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4754 The public key verification and especially a certificate
4755 verification is asynchronous procedure.
4757 Added new SILC_SKE_STATUS_PENDING status to indicate the
4758 request is pending and a callback will be called to finalize
4761 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4762 indicate that remote end did not send its public key (or
4763 certificate), even though we require it. Added check for this
4764 condition in the SKE. This was a security bug, now fixed.
4766 Defined new SilcSKEVerifyCbCompletion callback that is called
4767 when the verification process is completed.
4769 The affected files lib/silcske/silcske_status.h and
4770 lib/silcske/silcske.[ch].
4772 * Changed the verify_public_key client operation to be async
4773 as well. Defined SilcVerifyPublicKey callback that is used to
4774 indicate the success of the public key verification process.
4776 Changed the server and client to use the new async client
4779 * Changed the Irssi SILC client's internal scheduler to be called
4780 twice as many times as it used to be. As a result the client
4781 should be a bit faster now. Affected file is
4782 irssi/src/silc/core/silc-core.c.
4784 * Added support to Irssi SILC client of asynchronous public key
4785 verification and passphrase inquiry. Affected file is
4786 irssi/src/silc/core/silc-core.c.
4788 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4790 * Do not say "You have left channel %s" in client library.
4791 Moved it to the application. Affected files are
4792 lib/silcclient/command.c and silc/client_ops.c.
4794 * Fixed silc_client_get_clients. Command context was not
4795 duplicated and was freed memory in the callback. Affected
4796 file lib/silcclient/idlist.c.
4798 * Do not say "you are now talking..." on JOIN command in the
4799 client library. The appliation must handle it.
4801 * Do not say ".. changed topic to" in command reply in the
4802 client libary. The application must handle it.
4804 * Fixed TOPIC command sending in the client library.
4806 * Fixed a memory leak in silc_client_command_free in the file
4807 lib/silcclient/command.c.
4809 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4811 * Imported a modified version of Irssi client to the source tree.
4812 The Irssi will be used to create a new client called
4813 Irssi SILC. Imported to irssi/.
4815 Added silc_core_init_finish function to the Irssi. Affected
4816 file irssi/configure.in.
4818 A lot changes in the Makefile.ams around the irssi tree.
4820 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4822 * Do not rehash if the new size is same as the old size of the
4823 hash table, in the silc_hash_table_rehash*. The affected file
4824 lib/silcutil/silchashtable.c.
4826 * Replaced hash_table_del_by_context calls from the server
4827 (when channel->user_list and client->channels) to the
4828 hash_table_del as it is sufficient and faster.
4830 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4832 * Added silc_hash_table_list, silc_hash_table_get and the
4833 SilcHashTableList structure to provide an alternative way to
4834 traverse the hash table. The affected files are
4835 lib/silcutil/silchashtable.[ch].
4837 * Changed the server's idlist routines to use the hash table
4838 routines to optimize the code.
4840 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4842 * Replaced the client entry's `channel' list and channel entry's
4843 `user_list' list to hash tables for optimized lookup. Changed
4844 the code to use the hash table interface around the code.
4845 Affected file lib/silcd/idlist.[ch].
4847 * Added `auto_rehash' boolean argument to the function
4848 silc_hash_table_alloc to indicate whether the hash table should
4849 auto-rehash when it thinks is appropriate time. It will
4850 increase the hash table size if the there is twice as much
4851 entries in the table than the size of the table, and will
4852 decrease the size if there are twice as less entries than
4853 the size of the table.
4855 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4857 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4859 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4861 * silc_idcache_purge_by_context deletes the entry now by context
4862 as it is supposed to do. Affected file lib/silccore/idcache.c.
4864 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4865 client is not anymore valid (WHOWAS givens the info) and not
4866 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4868 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4870 * Removed the `data' and `data_len' arguments from the ID Cache
4871 interfaces and added `name' argument. ID Cache does not handle
4872 anymore the binary data only a names associated with given ID.
4874 * When hashing a Client ID with silc_hash_id the entire ID is
4875 not hashed anymore, instead only the hash of the Client ID is
4876 hashed. This way we can access the Client ID from the cache
4877 with Client ID but with the hash of the ID (which is a hash of
4878 the nickname) as well without any difference in performance.
4880 Added also silc_idcache_find_by_id_one_ext to do one on one
4881 searching when we have the actual ID. Added also function
4882 silc_hash_client_id_compare. The affected files are
4883 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4885 * When hashing the name associated with a ID it is always done
4886 in lowercase. This way we can access the cache without worrying
4887 about case-sensitivity, even though, for example nicknames are
4890 * Fixed a bug in server with channel message sending. It put
4891 wrong ID type as destination ID. The affected file
4892 silcd/packet_send.c.
4894 * silc_idcache_del_by_context now deletes from all hash tables
4895 by context. Affected file lib/silccore/idcache.c.
4897 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4899 * Changed the client library to use the new ID Cache interface.
4900 Changes around the source tree.
4902 * Added silc_hash_table_rehash_ext to rehash with specific
4903 hash function. Affected file lib/silcutil/silchashtable.[ch].
4905 * Added silc_hash_string_compare to compare two strings in the
4906 hash table. Affected file lib/silcutil/silcutil.[ch].
4908 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4910 * Added new function silc_idcache_del_by_context into the
4911 lib/silccore/idcache.[ch].
4913 * Changed the server's ID list routines to use the new ID Cache
4914 interface. Changes around the source tree.
4916 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4918 * Added silc_hash_table_del[_by_context]_ext functions in to the
4919 lib/silcutil/silchashtable.[ch].
4921 Removed silc_hash_table_find_all* routines and added new
4922 silc_hash_table_find_foreach to replace them.
4924 Added silc_hash_table_replace_ext function as extended
4925 replacing function. Separated the simple hash table interface
4926 from the extended hash table interface in the file
4927 lib/silcutil/silchashtable.h.
4929 * Fixed minor bugs and changed it to use some of the new
4930 hash table functions in lib/silccore/idcache.c
4932 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4934 * Added new function silc_hash_table_find_all to return all keys
4935 in the hash table by the specified key. As the hash table is
4936 collision resistant it also makes it possible to have several
4937 duplicate keys in the hash table. This function may be used to
4938 find all of the keys from the hash.
4940 Added user_context arguments to the SilcHashFunction,
4941 SilcHashCompare and SilcHashDestructor to deliver user specified
4944 Added new fuctions silc_hash_table_find[_all]_ext to do
4945 extended lookup with specified hash and compare functions and
4946 specified user contexts.
4948 Added new function silc_hash_table_add_ext to add the key
4949 with specified hash function and user context.
4951 Added new function silc_hash_table_foreach to traverse all
4952 entrys in the hash table. Added SilcHashForeach callback
4955 Added new function silc_hash_table_del_by_context to delete
4956 the entry only if the context associated with the key matches.
4958 Affected files are lib/silcutil/silchashtable.[ch].
4960 * Removed silc_hash_[server/client/channel]_id and added just
4961 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4962 silc_hash_id_compare to compare two ID's using as the hash table
4963 comparison function. Added also silc_hash_data to hash
4964 binary data and silc_hash_data_compare to compare it.
4966 * Removed silc_idlist_find_client_by_hash as it is not needed
4967 anymore. Affected file silcd/idlist.[ch].
4969 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4970 to use internally the SilcHashTable. The new ID Cache is a lot
4971 faster than the old one. Some of the ID Cache interface was also
4972 rewritten and obsolete and stupid functions were removed.
4974 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4976 * Added entry_count field to the SilcHashTable to keep the number
4977 of the entries in the table. Implemented the function
4978 silc_hash_table_rehash. Added new function
4979 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4981 Fixed a minor bug in silc_hash_table_free.
4983 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4984 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4985 into the lib/silcutil/silcutil.[ch].
4987 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4989 * Implemented a collision resistant hash table into the
4990 lib/silcutil/silchashtable[ch]. See the header and the source
4991 for the SilcHashTable API.
4993 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4995 * Merged dotconf version 1.0.2 into lib/dotconf.
4997 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4999 * Do not compile anything in lib/silcsim/* if the SIM support
5000 is not enabled. The tree should now compile without problems
5003 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5005 * Compiled the SILC under cygwin. Compiled and tested briefly
5006 without problems. More tests needed. The SIMs didn't compile
5009 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
5011 * Fixed possible crash in silc_get_username in the
5012 lib/silcutil/silcutil.c.
5014 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5016 * Fixed a va_arg in silc/client_ops.c.
5018 * Oops, RC5 routines were named AES and caused some problems
5019 when not using SIM's. Affected file lib/silccrypt/rc5.c.
5021 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5023 * Added new SilcIDIP structure into the lib/silccore/id.h and
5024 replaced the old `ip' fields from all SILC ID's to that type.
5025 This is a step towards IPv6 support.
5027 The silc_id_get_len takes now the ID as an extra argument.
5028 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
5029 both IPv4 and IPv6 based ID's.
5031 The affected files are lib/silccore/id.[ch] and other files
5032 around the tree using these routines.
5034 * Removed the ID length arguments in server from various
5035 silc_server_send_notify_* routines -> they are not needed
5038 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5040 * Fixed memory leak in silc_encode_pem_file in the file
5041 lib/silcutil/silcutil.c.
5043 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5045 * Check minor version as well in the SKE. Affected files are
5046 silcd/protocol.c and lib/silcclient/protocol.c.
5048 * Added --identifier option to the server so that an identifier
5049 can be when creating the public key for the server. Affected
5050 file is silcd/silcd.c.
5052 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
5053 lib/silccrypt/silcpkcs.c.
5055 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5057 * Register default ciphers and stuff when using -C option with
5058 the server. Affected file sildc/silcd.c.
5060 * Put back the servers public key filename format, it is better
5061 than the new one. For now, the client keys are saved with the
5062 new filename format. The affected file silc/client_ops.c.
5064 * Implemented the Cipher API for the rest of the ciphers that
5065 did not implement it or implemented it the wrong way.
5067 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5069 * Register default ciphers and stuff when using the -S option
5070 in the client. Affected file silc/silc.c. Same also when
5071 creating new key pair with -C option.
5073 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5075 * Fixed the silc_verify_public_key client operation function to
5076 save the public keys differently. The fingerprint is now
5077 used as filename and not the hostname. This way also the
5078 client keys are saved uniquely and not with hostnames. The
5079 affected file is silc/client_ops.c.
5081 * Trimmed the silc_hash_fingerprint function to remove extra
5082 whitespaces from the end of the fingerprint. The affected
5083 file is lib/silccrypt/silchash.c.
5087 * Added silc_cipher_register_default function to register all
5088 default ciphers. It can be used when configuration files
5089 does not exist and the application does not want any specific
5090 ciphers in any specific order.
5092 The SilcDList is now used as silc_cipher_list dynamically
5093 allocated cipher list. Removed the static list all together
5094 and now all ciphers must be allocated to the dynamic list.
5095 The silc_cipher_alloc routine was changed to check only the
5098 All silc_cipher_* routines that used to return int returns
5101 The affected files lib/silccrypt/silccrypt.[ch].
5103 * The same thing was done to silc_hash_* as for silc_cipher_*
5104 routines. Affected files lib/silccrypt/silchash.[ch].
5106 * The same thing was done to silc_pkcs_* as for silc_cipher_*
5107 routines. Affected files lib/silccrypt/silcpkcs.[ch].
5108 Added also silc_pkcs_[un]register[_default] functions.
5109 Removed the data_context from the PKCS API.
5111 * Added silc_hmac_register_default function to register default
5112 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
5113 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
5114 to unregister all hmacs at once.
5116 * Register the default ciphers, hash functions, PKCSs and HMACs
5117 if client's configuration file does not exist. The affected
5120 * The client did not load the hash functions from the SIM
5121 modules at all. Added support for this. Affected file is
5122 silc/clientconfig.c.
5124 * When decoding public key with silc_pkcs_public_key_decode, check
5125 the supported algorithm only if PKCS are registered. Affected
5126 file lib/silccrypt/silcpkcs.c. The same was done with the
5127 silc_pkcs_private_key_decode.
5129 * Fixed the SILC List routines to keep the list always in order.
5130 It used to change the list's order when traversing the list but
5131 not it preserves the order. Affected file lib/trq/silclist.h.
5133 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5135 * Added the client library to use the SilcSocketConnection's
5136 reference counter (by silc_socket_dup) to prevent the bug that
5137 the socket object may be freed underneath async operation.
5139 * The name resolv library checking fixes in the configure.in.pre.
5142 * Created new version of the protocol drafts for future
5143 development. The -03 drafts are the ones that will be changed
5144 in the trunk now and the -02 will remain as they are.
5146 * Send list of CUMODE notifys to the router when announcing
5147 the channel users to the router. Affected file silcd/server.c.
5148 If the router receiving channel founder CUMODE for a channel
5149 that already has channel founder it will send CUMODE notify
5150 to the sender to remove the channel founder rights from the
5151 announced client. Affected file silcd/packet_receive.c.
5153 * The CUMODE notify may now use Server ID as well as the entity
5154 who changes the mode. Updated protocool specs.
5156 * Updated INSTALL and README files.
5158 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5160 * New web pages in the http://silc.pspt.fi. The pages was
5165 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5167 * Implemented the [DenyConnectin] config section in the server.
5168 Added silc_server_config_denied_conn to check whether incoming
5169 connection is denied. Affected file silcd/serverconfig.[ch].
5171 * Do not check the ports when checking the incoming configuration
5172 data if the port is 0, meaning any. Affected file is
5173 silcd/serverconfig.c.
5175 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5177 * Fixed buffer overflow in silc_string_compare in the file
5178 lib/silcutil/silcutil.c.
5180 * Fixed double free in silc_server_command_leave in the file
5183 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5185 * Fixed the version checking in the server. Affected file is
5188 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5190 * Fixed the configuration data fetching when accepting new
5191 connections in the server. Affected file silcd/server.c.
5193 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5195 * Added `sender_entry' argument to the function
5196 silc_server_packet_relay_to_channel so that we can check
5197 whether some destination actually belongs to the same route
5198 the sender belongs (ie, we must not resend the packet to the
5199 sender). Affected file silcd/packet_send.[ch].
5201 * Added `servername' field to the SilcClientEntry in the server
5202 to hold the name of the server where client is from. Affected
5203 file is silcd/idlist.h.
5205 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5207 * Moved the channel message encrypting in the router betwen
5208 router connections from silc_server_channel_message to the
5209 silc_server_packet_relay_to_channel since we want to check
5210 whether we have anybody channel before encrypting anything.
5211 Affected files silcd/packet_[receive/send].c.
5213 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5215 * Fixed the [AdminConnection] server config section to support
5216 multiple entries. Affected file silcd/serverconfig.c.
5218 * Added support into the server to check the validity of the
5219 incoming connection before executing any KE or authentication
5222 * The connection configuration is now saved to the KE and
5223 connection auth protocol contexts and not fetched anymore in
5224 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
5226 * The local hosts listenning address and port is also resolved
5227 now when starting the server. We want to have the socket object
5228 to include the real address and port for the listener. Added
5229 new function silc_net_check_local_by_sock into the files
5230 lib/silcutil/silcnet.[ch].
5232 * Fixed a broadcast bug in server -> do not broadcast if we
5235 * Fixed a routing bug. Do not route broadcast packets ever.
5236 Broadcast packets must be processed always and not routed since
5237 they may be destined to some other host than yourself and thus
5238 would get routed without no good reason. Affected file is
5241 * Added function silc_server_config_is_primary_route to check
5242 whether primary router connection has been configured (a router
5243 configuration that we are initiating). If there is not, we
5244 will assume that there is only two routers in the SILC network
5245 and we will use the incoming router connection as our primary
5246 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
5248 * Changed the order of the broadcasting. Broadcast _after_ the
5249 packet has been processed not before. Affected file is
5252 * Fixed a [ClientConnection] parsing bug. The port was never
5253 parsed correctly thus resulting to port 0. Affected file
5254 silcd/serverconfig.c.
5256 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
5257 argument and did not set the broadcast packet flag. Affected
5258 file silcd/packet_send.c. Fixed same bug in the function
5259 silc_server_send_notify as well.
5261 * If we receive NEW_ID packet for our own ID in the server, ignore
5264 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5268 * Removed the nickname from the Private Message Payload.
5269 Updated the code and the protocol specs.
5271 * Updated protocol specs for submitting to the IETF.
5273 * Tweaked the Random Number Generator a bit. Affected file
5274 lib/silccrypt/silcrng.c. Exported a new function
5275 silc_rng_[global]_add_noise which can be used to add more
5278 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5280 * Do not parse packets with different timeout when protocol
5281 is active -> may cause problem with rekey. Affected file
5284 * When server receives signoff notify it must not create
5285 new channel key if the client is on any channels since the
5286 sender of the signoff notify will create it.
5288 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5290 * Added printing of error messages during SKE protocol from the
5291 failure packet sent by server during SKE. Affected file
5294 * Removed the client's failure_callback handling with timeout
5295 and handle it immediately when received.
5297 * The SKE library returned wrong type in SUCCESS and FAILURE
5298 packets. They must be 32 bit MSB not 16 bit MSB.
5300 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5302 * Ok, rewrote the logic of the re-key and now it seems to work.
5303 I tested it on high traffic with frequent re-keys without
5304 problems. Added hmac_receive (and renamed hmac to hmac_send)
5305 in SilcClientConnection in lib/silcclient/client.h and
5306 in SilcIDListData in silcd/idlist.h. Also, removed the
5307 SilcPacketParserContext's cipher and hmac fields as they are
5308 not needed anymore and actually caused some problems when
5309 the ciphers and hmac's changed underneath the packet parser.
5311 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5313 * If re-key protocol is active then process the incoming packets
5314 synchronously since we must assure that icoming packets encrypted
5315 with the old key is processed before the new keys is set to
5316 use. This is true other packets than for REKEY packets.
5317 Affected file silcd/server.c. The same was done to client library
5318 as well, affected file lib/silcclient/client.c.
5320 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5322 * Fixed bug in client and server to accept the force send if
5323 the packet is send from silc_[server/client]_packet_process
5324 function. Otherwise the packets are never delivered, oops.
5326 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5328 * Disable force sending of packets when REKEY protocol is active.
5329 We must assure that no packet is sent directly when rekey is
5330 performed. All packets must be sent through packet queue.
5331 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
5332 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
5333 function is silc_[server/client]_packet_send_real to check
5336 * Replaced the SIM paths from example config files to
5337 /usr/local/modules. Also, make install creates now
5338 /usr/local/silc/logs directory to hold all the SILC server
5341 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5343 * Made the configure.in.pre work on Solaris. Patch by salo.
5345 * Made all ciphers compatible with non-x86 machines. Defined
5346 CBC mode macros into lib/silccrypt/ciphers_def.h.
5348 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5350 * Fixed the make install.
5352 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5354 * When MAC computation fails the silc_packet_decrypt returned 0
5355 even though it was supposed to return -1. Fixed this. The
5356 affected file is lib/silccore/silcpacket.c.
5358 * Do not replace the config files in /etc/silc (in make install)
5359 if they already exist. Affected file ./Makefile.am.
5361 * Do not send re-key packets immediately but through packet queue.
5362 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
5364 * Changed silc_net_check_host_by_sock to return FALSE if the
5365 IP/DNS could not be resolved. Though, it returns the IP address
5366 now even if it could not resolve it (but returns also FALSE).
5367 Affected file lib/silcutil/silcnet.[ch].
5369 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5371 * Added silc_pkcs_decode_identifier to decode the public key's
5372 identifier. Affected file lib/silccrypt/silpkcs.[ch].
5373 Added also silc_pkcs_free_identifier. Added also new context
5374 SilcPublicKeyIdentifier.
5376 * Added -S option to the silc client. It is used to dump the
5377 contents of the specified public key file.
5379 * Changed the PKCS api to return the public key length when
5380 setting the public key.
5382 * Fixed a fatal bug in the public and private key file loading.
5383 Affected file lib/silccrypt/silcpkcs.c.
5385 * Execute the packet parsing for client with zero (0) timeout
5386 if the protocol is active. Affected file silcd/server.c.
5388 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5390 * Made the key generation options to the silcd program. Added
5391 -C option, equivalent to client's option.
5393 * Added new [ServerKeys] config section to the server. It
5394 configures the server's public and private key.
5396 * Defined generic Public Key Payload into the protocol
5397 specification to send specific type of public keys and
5400 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
5401 public key or certificate.
5403 * Implemented the GETKEY command to the server and to the
5404 client library and on user interface.
5406 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5408 * Made preliminary `make install' work.
5410 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5412 * Added SilcServerRekey context into silcd/idlist.h.
5414 * Added the PFS support as defined in the specification to the
5415 SKE protocol. Affected files lib/silcske/*.c.
5417 * Added `ske_group' field to the SilcServerRekey context to hold
5418 the number of the SKE group that is used with PFS in re-key.
5419 Affected file silcd/idlist.h.
5421 * Added PFS re-key support to the server. Affected file is
5424 * Added silc_protocol_cancel to cancel execution of the next
5425 state of the protocol. Affected file is
5426 lib/silccore/silcprotocol.[ch].
5428 * Added the re-key support with and without PFS to the client
5429 library. Re-key is performed once in an hour, by default.
5431 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
5432 Added silc_client_rekey_callback and silc_client_rekey_final.
5433 Affected files are lib/silcclient/protocol.[ch] and
5434 lib/silcclient/client.[ch].
5436 * Removed the `hmac_key' and `hmac_key_len' fields from the
5437 SilcClientConnection structure; not needed. Affected file is
5438 lib/silcclient/client.h.
5442 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5444 * Do not ask whether user wants to use the negotiated private key
5445 for private messages, just use it. Affected file is
5446 silc/local_command.c.
5448 * Added `send_enc_key' and `enc_key_len' fields to the
5449 SilcIDListData structure since they are needed in the re-key
5450 phase. Affected file is silcd/idlist.[ch].
5452 * Implemented the simple re-key protocol into the server.
5453 Affected files silcd/server.c and silcd/protocol.[ch]. The
5454 re-key will be performed once in an hour, by default.
5456 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
5457 Added silc_server_rekey, silc_server_rekey_callback and
5458 silc_server_rekey_final.
5460 * Removed Tunneled flag from the protocol. Updated the code
5461 and the specifications.
5463 * Adde `pfs' field to the SilcIDListData to indicate whether
5464 the PFS is to be performed in the re-key. Affected file is
5467 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5469 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
5470 int64 of at least the xintXX size. If void * is less that 4
5471 bytes uint32 * will be used. Defined bool as boolean.
5473 * Changed _ALL_ unsigned long and unsigned int to uint32,
5474 unsgined short to uint16 in the source tree.
5476 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
5477 not handle clients that has entry->data.registered == FALSE.
5478 They are not in the network anymore. Affected file is
5481 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5483 * Implemented the sending of the SERVER_SIGNOFF notify in the
5484 server. Affected file is silcd/server.c.
5486 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
5487 Added also silc_notify_payload_encode_args into the
5488 lib/silccore/silcnotify.[ch].
5490 * Implemented ther SERVER_SIGNOFF notify handling in the server.
5491 Affected file silcd/packet_receive.c.
5493 * Implemented the SERVER_SIGNOFF notify handling in the client
5494 library. Affected file lib/silcclient/client_notify.c. Also,
5495 implemnted the printing of the SERVER_SIGNOFF info to the
5496 application. Affected file silc/client_ops.c.
5498 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
5499 if the deleting was successful. Affected file silcd/idlist.[ch].
5501 * Added support for public key authentication in the connection
5502 authentication protocol in the client library. Affected file
5503 lib/silcclient/protocol.c.
5505 * Changed the server's silc_idlist_get_clients_by_* interface
5506 to support already allocated array so that new entries may be
5507 added to pre-allocated array. Affected file silcd/idlist.[ch].
5508 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
5509 and command replies.
5511 * All command reply functions in the server now calls the
5512 pending command callback even if error occured. This way the
5513 error will be delivered to the client as well. Affected files
5514 silcd/command.c and silcd/command_reply.c.
5516 * Fixed INFO command to return local server's info if no server
5517 was provided. Affected file lib/silcclient/command.c.
5519 * Removed RESTART command for good. Updated the code and the
5522 * Rewrote parts of the task system. It is a bit simpler now.
5523 Removed unsued task priorities. The affected files are
5524 lib/silcutil/silctask.[ch].
5526 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5528 * Moved the USERS printing from the library to the application.
5529 Affected files lib/silcclient/command.c and silc/client_ops.c.
5531 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5535 * Added channel key re-key support. The re-key is perfomed
5536 only by the router and is done once in an hour. Added `rekey'
5537 field to the SilcChannelEntry in the server. Affected files
5538 silcd/server.c and silcd/idlist.h.
5540 * Added silc_task_unregister_by_context into the file
5541 lib/silcutil/silctask.[ch].
5543 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5545 * Added SILC_UMODE_GONE mode to indicate when the client is not
5546 present in the SILC network. Added also support to the local
5547 command AWAY that will set this mode. Added support of showing
5548 "xxx is gone" in WHOIS command. The USERS command shows the
5549 gone status as well.
5551 * Fixed setting server and router operator privileges in the
5552 server's UMODE command. Affected file silcd/command.c.
5554 * Merged the SKE KE1 and KE2 payloads into one payload. The
5555 new KE payload is equivalent to the old KE2 payload.
5557 Cleaned up the SKE Start Payload parsing. It now uses the
5558 simple buffer unformatting to do the parsing. A lot faster
5561 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
5562 to the SKE that is used to indicate whether both of the SKE
5563 parties should perform authentication. By default only the
5564 responder performs authentication. By setting this flag also
5565 the initiator must do authentication. By default it is unset
5566 since in normal SKE case, client to server connection, only
5567 the responder should do authentication. When doing SKE between
5568 two clients both should perform authentication. Updated the
5569 code and the protocol specs.
5571 * A little fix to IDENTIFY command in the server. Search the
5572 client first by hash not nickname. Affected file is
5575 * Fixed the silc_client_close_connection to support closing
5576 the client to client connections wihtout deleting too much
5577 data. Affected file lib/silcclient/client.c.
5579 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
5580 are received if protocol used to be active but is not anymore
5581 the application would crash due to NULL pointer dereference.
5582 Affected files silcd/server.c and lib/silcclient/client.c.
5584 * Added `hash' field to the SilcClientConnection to include
5585 the hash function negotiated in the SKE protocol.
5587 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
5588 to set the channel founder authentication data. A client can
5589 claim the founder rights later by providing the authentication
5590 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
5591 This way the channel founder can regain the channel founder
5592 privileges even it is left the channel. This works only on
5593 local server and the client must be connected to the same
5594 server to be able to regain the founder rights. Updated the
5595 protocol specs accordingly.
5597 Added support to the CMODE command in the client to set the
5598 founder auth data. Read the README to see how to set it.
5600 Added support to the CUMODE command to claim the founder
5601 rights. Read the README to see how to do it.
5603 Added support for the founder authentication to the Channel
5604 Entry in the server. Affected file silcd/idlist.h.
5606 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
5607 server's CMODE command. Affected file silcd/command.c.
5609 * Added the following new functions into lib/silccore/silcauth.[ch]:
5610 silc_auth_get_method and silc_auth_get_data.
5612 * The server now saves the remote hosts public key to the
5613 SilcIDListData pointer. Affected file silcd/protocol.c.
5615 * The normal server now does not remove the channel entry from
5616 the cache if the founder authentication data is set. It used
5617 to remove it if the founder was the last one on the channel on
5618 the server and left the channel. The auth data is saved and
5619 if the channel is re-joined later the old entry is used with
5620 the old auth data. Affected files silcd/command_reply.c and
5623 * Removed the `pkcs' field from the SilcIDListData structure
5624 in the server; it is not used. Affected file silcd/idlist.h.
5626 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5628 * Fixed packet processing on slow links. Partial packets were
5629 never re-processed because the incoming data buffer was cleared
5630 by the application. Application must not directly clear the
5631 sock->inbuf, the packet processing routines handle it. Fixed
5632 this in client library and in server.
5634 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5636 * Fixed the WHOIS and IDENTIFY send reply function to really
5637 check whether to send list or just one entry. Affected file
5640 * Cleaned up the LEAVE command's channel key distribution. The
5641 affected file silcd/command.c.
5643 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
5644 can enforce the channel mode as well. In that case the ID
5645 includes the ID of the server. The code now enforces the
5646 mode change if the router have different mode than the server.
5648 * The notify client operation with CMODE_CHANGE notify can now
5649 return NULL client_entry pointer if the CMODE was not changed
5650 by client. Application must check for this.
5652 * Added <Server ID> argument to INFO command to support server
5653 info fetching by Server ID.
5655 * Added silc_server_announce_get_channel_users to get assembled
5656 packets of channel users of the specified channel. Affected
5657 file silcd/server.[ch].
5659 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
5660 was freed underneath the ID Cache.
5662 * Re-announce clients when the server received CHANNEL_CHANGE
5663 notify from the router. Affected file silcd/packet_send.c.
5665 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5667 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
5668 crashed since it did not handle the fact that there is no cipher
5669 called "3" and didn't check the error condition. Now fixed.
5671 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
5672 flag. It can be used to send message requests.
5674 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5676 * Implemented the RESTART command in the client.
5678 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
5679 notice type messages. Added notice printing to the user
5682 * The channel keys are not re-generated if the channel's mode
5683 is PRIVKEY, ie private key on the channel exists. Affected
5684 files silcd/server.c and silcd/command.c.
5686 * Fixed a little bug in channel message delivery when channel
5687 private keys are set in the server. Affected file is
5688 silcd/packet_send.c.
5690 * Changed the setting on channel->on_channel = TRUE from the
5691 silc_client_save_channel_key to the JOIN command reply. The
5692 key payload is not received if the private channel key is set.
5693 Affected file lib/silcclient/command_reply.c and the
5694 lib/silcclient/client_channel.c.
5696 * When the CMODE_CHANGE notify is sent and the channel private
5697 key mode is removed the channel key must be re-generated in
5698 other cells as well. Added this support for the router in the
5699 silcd/packet_receive.c.
5701 * Added new local command NOTICE to send notice message on
5702 channel. Affected file silc/local_command.[ch].
5704 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5706 * Added new local command ME to the client. It is used to send
5707 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
5708 some action. Affected file silc/local_command.[ch].
5710 * Changed channel_message and private_message client operations
5711 to deliver the message flags to the application. Added also
5712 the `flags' arguments to the silc_client_send_channel_message
5713 and silc_client_send_private_message functions. Affected file
5716 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5718 * Redefined the Private Message Payload to support private message
5719 keys and to support the new private message flags. Updated
5720 the protocol specs. Flags makes it possible to have for example
5721 CTCP style messages.
5723 * Added new type SilcPrivateMessagePayload and defined an API
5724 for it in the lib/silcclient/silcprivate.[ch].
5726 * Tested private message private keys successfully. Tested the
5727 private message key set, unset and list commands with the new
5730 * Redefined the Channel Message Payload to include the channel
5731 message flags (equal with private message flags) to support
5732 for example CTCP style messages.
5734 * Defined some of the message (for channel and private message)
5735 flags. Updated the protocol specs and added the flags to the
5736 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5738 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5740 * Added SilcKeyAgreementStatus type to the key agreement routines
5741 to indicate the current status and error if one occured.
5742 The status types are defined in the lib/silcclient/silcapi.h.
5744 * Added new local command KEY that is used to set and unset private
5745 keys for channels, set and unset private keys for private messages
5746 with remote clients and to send key agreement requests and
5747 negotiate the key agreement protocol with remote client. The
5748 key agreement is supported only to negotiate private message keys,
5749 it currently cannot be used to negotiate private keys for channels,
5750 as it is not convenient for that purpose.
5752 * Fixed a minor pending callback setting bug in the function
5753 silc_client_get_client_by_id_resolve, now the function works.
5754 Affected file lib/silcclient/idlist.c.
5756 * Added function silc_net_get_local_port to get local bound
5757 port by socket. Added to lib/silcutil/silcnet.[ch].
5759 * Added `sockets' and `sockets_count' fields to the SilcClient
5760 object. They hold the sockets of the listenning sockets in
5761 the client. Listenning sockets may be for example the key
5762 agreement server. Affected file lib/silcclient/client.[ch].
5763 Added functions the silc_client_add_socket and the
5764 silc_client_del_socket. They are exported to the application
5767 * Added ~./silc/clientkeys to support other client's public keys.
5769 * Renamed verify_server_key client operation to verify_public_key
5770 and added one argument to indicate the type of the connection
5771 (server, client etc.).
5773 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5775 * Added silc_server_connection_auth_request to handle the
5776 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5777 silcd/packet_receive.[ch].
5779 * Added silc_server_send_connection_auth_request into the
5780 silcd/packet_send.c to send the connection auth request packet.
5782 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5785 * Fixed the public key authentication in responder side in the
5786 server. The `auth_data' pointer includes the SilcPublicKey
5787 not the path to the public key. Affected file silcd/protocol.c.
5789 * Implemented the public key authentication in the initiator side
5790 in the server. Affected file silcd/protocol.c.
5792 * Removed the [RedirectClient] config section from the server
5793 configuration. Is not needed and I don't want to implement it.
5795 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5797 * Cleaned up the CMODE command in the server. It now works
5798 correctly and supports all the modes defined in the protocol.
5799 Affected file is silcd/command.c.
5801 * Added `hmac_name' field to the SilcChannelEntry in the server
5802 to hold the default HMAC of the channel. It can be set when
5803 creating the channel (with JOIN command). Affected files
5806 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5807 type to indicate the change of the current cipher and hmac
5808 on the channel. Client can safely ignore the <cipher> argument
5809 (if it chooses to do so) since the CHANNEL_KEY packet will
5810 force the channel key change anyway. The <hmac> argument is
5811 important since the client is responsible of setting the new
5812 HMAC and the hmac key into use.
5814 * Fixed the CMODE command in the client library as well.
5816 * Tested CMODE command in router environment successfully.
5818 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5820 * Show the version of the remote client (or server) when connecting
5821 to the server. It is logged to the log file. Affected file
5822 is silcd/protocol.c.
5824 * Fixed the KILLED notify handling in the client library. The
5825 client must be removed from all channels when receiving the
5828 Also, do not remove the client entry when giving the KILL
5829 command but when the KILLED notify is received.
5831 * Removed silc_idlist_find_client_by_nickname from the server.
5832 Not needed anymore. Affected files silcd/idlist.[ch].
5834 * Implemented the CHANNEL_CHANGE notify type handling to the
5835 server. Affected file silcd/server.c.
5839 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5841 * Added silc_server_send_notify_invite to send the INVITE
5842 notify between routers.
5844 * Implemented the INVITE command correctly to the server.
5846 * Implemented the INVITE notify type handling in the server.
5848 * Implemented the INVITE command to the client library and on the
5851 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5853 * Added function silc_server_get_client_resolve to find the
5854 client entry by ID from all ID lists and then resolve it
5855 (using WHOIS) if it cannot be found. Affected file is
5858 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5860 * Implemented the BAN command to the client library.
5862 * The JOIN command in the server now checks the invite list
5865 * Changed the silc_command_reply_payload_encode_va and the
5866 silc_command_payload_encode_va to support that if argument is
5867 NULL it ignores and checks the next argument. Affected file
5868 lib/silccore/silccommand.c.
5870 * Added silc_server_send_notify_ban to send the BAN notify
5871 type between routers.
5873 * Chaned the silc_notify_payload_encode to support that if
5874 argument is NULL it ignores and checks the next argument.
5875 Affected file lib/silccore/silcnotify.c.
5877 * Tested ban lists in router environment successfully.
5879 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5881 * Implemented BAN command to the server, in silcd/command.[ch].
5883 * Removed the BAN and INVITE_LIST modes from the CMODE command
5886 * Added function silc_string_match to regex match two strings.
5887 Affected files lib/silcutil/silcutil.[ch].
5889 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5891 * Redefined parts of the SilcChannelEntry in the server to support
5892 the new ban and invite lists.
5894 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5896 * Redefined the INVITE command. The same command can be used to
5897 invite individuals to the channel but also to manage the invite
5898 list of the channel (to add to and remove from the invite list).
5899 Updated the protocol specs.
5901 * Added new command SILC_COMMAND_BAN that can be used to manage
5902 the ban list of the channel. Updated the protocol specs.
5904 * Removed the channel modes: the SILC_CMODE_BAN and the
5905 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5906 in the CMODE command. The equivalent features are now available
5907 using INVITE and BAN commands. Updated the protocol specs.
5909 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5910 in the network about change in the current ban list. The notify
5911 type is not used by the client.
5913 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5914 support the invite lists.
5916 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5918 * Added new function silc_string_regexify that converts string
5919 including wildcard characters into regex string that can
5920 be used by the GNU regex library. Added into the file
5921 lib/silcutil/silcutil.[ch].
5923 Added silc_string_regex_combine to combine to regex strings
5924 into one so that they can be used as one regex string by
5925 the GNU regex library. Added into the file
5926 lib/silcutil/silcutil.[ch].
5928 Added silc_string_regex_match to match two strings. It returns
5929 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5931 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5933 * Imported GNU regex to the soruce tree into lib/contrib.
5934 Fixed some compiler warning from the regex.c.
5936 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5938 * Fixed MOTD command in the server to work in router environment.
5940 * Fixed the MOTD command in the client library to support
5941 the server argument in the command.
5943 * Added `nickname_len' argument to the silc_idlist_add_client
5944 in the server, as the `nickname' argument may be binary data
5947 * Added silc_idlist_get_channels to return all channels from
5950 * Implemented LIST command to the server. Affected file is
5953 * Implemented the LIST command to the client library and on the
5956 * Added [<user count>] argument to the LIST command reply.
5957 With private channels the user count is not shown.
5959 * Updated TODO and README.
5961 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5963 * The client entry's data.registered must be TRUE even with
5964 global client entry on global client list. The data.registered
5965 is used to check whether the client is anymore in the network,
5966 for example with WHOWAS command so it must be valid.
5968 * Fixed the WHOWAS command in the server. It now actually works
5969 in router environment. Added function into silcd/command_reply.c
5970 silc_server_command_reply_whowas_save.
5972 * Added silc_idlist_purge function to the silcd/idlist.c
5973 to periodically purge the ID Cache.
5975 * Fixed INFO command in the server. It works now in router
5976 environment. Added <server name> argument to the INFO command
5977 reply. Updated the protocol specs.
5979 * Fixed minor bug in silc_idcache_purge to not purge if the
5980 expire value is zero.
5982 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5983 they were buggy because of the WHOWAS information.
5985 * Fixed local command MSG to handle the async resolving of
5986 the remote client properly. It used to fail the first MSG.
5987 Affected file silc/local_command.c.
5989 * Added `data_len' field to SilcIDCache context.
5991 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5993 * Update TODO. Todo in commands in the server.
5995 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5997 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5998 used by routers as broadcast packet to inform other routers
5999 about the changed user mode.
6001 Implemented the notify handling in the server. Affected file is
6002 silcd/packet_receive.c. Added the function
6003 silc_server_send_notify_umode to the silcd/packet_send.[ch].
6005 * Added new generic Channel Payload and deprecated the New Channel
6006 Payload. The New Channel Payload is now the generic Channel
6009 * Added new argument `mode' to the silc_server_send_new_channel
6010 as it is required in the Channel Payload now.
6012 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
6013 and created a new and real SilChannelPayload to represent the
6014 new generic Channel Payload. Implemented the encode/decode
6015 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
6017 * Added silc_server_get_client_channel_list to return the list
6018 of channels the client has joined for WHOIS command reply.
6019 Affected file silcd/server.[ch].
6021 * Implemented the channel list sending in the WHOIS command reply
6022 in server and in the client.
6024 Implemented the channel list displaying on the user interface
6025 as well. Affected file silc/client_ops.c.
6027 * Added silc_channel_payload_parse_list to parse list of Channel
6028 Payloads. It returns SilcDList list of SilcChannelPayloads.
6029 Client for example can use this function to parse the list of
6030 channels it receives in the WHOIS command reply. The caller
6031 must free the list by calling silc_channel_payload_list_free.
6032 Affected files lib/silccore/silcchannel.[ch].
6034 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6036 * Added one new argument <user mode> to the WHOIS command reply
6037 to return the mode of the user in SILC. Updated the protocol
6040 Implemented it to the server and client.
6042 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6044 * Fixed the mode printing on the user interface on joining.
6045 Affected file silc/client_ops.c.
6047 * Implemented the UMODE command and user modes in general to the
6048 client library and to the user interface.
6050 * Implemented the UMODE command to the server.
6052 * The server now sends UNKNOWN_COMMAND error status if client sends
6053 unknown command. Affected file silcd/command.c.
6055 * All server commands now handle the command identifier the right
6056 way when sending the command reply to the client. The client can
6057 use to identify the command replies with the identifier.
6059 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6061 * Added silc_server_get_client_route to resolve the route to
6062 the client indicated by the client ID. Affected file is
6065 * Added silc_server_relay_packet as general function to relay
6066 packet to arbitrary destination. This deprecates functions
6067 like _send_private_message_key, _relay_notify etc. Affected
6068 file is silcd/packet_send.[ch].
6070 Removed silc_server_send_key_agreement,
6071 silc_server_send_private_message_key and
6072 silc_server_packet_relay_notify functions from the file
6073 silcd/packet_send.[ch].
6077 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
6078 server. Affected file silcd/packet_receive.[ch].
6080 * Implemented the KILL command to the client. Implemented the
6081 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
6082 Affected files lib/silcclient/command[_reply].c and
6083 lib/silcclient/client_notify.c. Implemented the KILL notify
6084 printing in the user inteface.
6086 * Fixed a lot silc_parse_nick memory leaks from the client
6087 library in the file lib/silcclient/command.c.
6089 * Changed the silc_server_send_notify_on_channels's `sender'
6090 argument from SilcSocketConnection to SilcClientEntry to
6091 check the sender as entry and not as connection object and not
6092 to send to the client provided as argument. The affected file
6093 is silcd/packet_send.[ch].
6095 * The notify packets that are destined directly to the client used
6096 to not to be processed by the server. Now changed that and the
6097 server processes all notify packets. After relaying the packet
6098 to the client the notify packet is processed in the server.
6100 * The silc_server_free_client_data now checks whether there is
6101 pending outgoing traffic for the client and purges the data to
6102 the network before removing the client entry.
6104 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6106 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
6107 an client is killed from the SILC Network. Updated the protocol
6110 Added new function silc_server_send_notify_killed to the
6111 silcd/packet_send.[ch].
6113 * Added function silc_server_packet_relay_notify to relay notify
6114 packets that are destined directly to a client. In this case
6115 the server does not process the notify packets but merely relays
6116 it to the client. Affected file silcd/packet_send.[ch].
6118 Added also silc_server_packet_process_relay_notify to check
6119 whereto relay the notify. Affected file is
6120 silcd/packet_receive.[ch].
6122 * Implemented the KILL command to the server.
6126 * Added the backup schema desgined last fall to the protocol
6127 specs for everyone to see. The specification is in the
6128 *-spec-xx.txt draft and the packet type definitions for the
6129 backup routers is in *-pp-xx.txt draft. Thusly, added also
6130 new packet type SILC_PACKET_CELL_ROUTERS.
6132 * A big security problem in the implementation discovered. The
6133 signoff of an client did not cause new channel key generation
6134 which it of course should've done. The channel keys must be
6135 always re-generated when client leaves (or signoffs) the channel.
6136 The silc_server_remove_from_channels funtion now handles
6137 the channel key re-generation.
6139 * Added `sender' argument to the silc_server_send_notify_on_channels
6140 to not to send the client provided as argument. Affected file
6141 silcd/packet_send.[ch].
6143 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6145 * Implemented OPER and SILCOPER commands into the server and
6148 * Added silc_auth_verify and silc_auth_verify_data to verify
6149 the authentication directly from the authentication payload.
6150 It supports verifying both passphrase and public key based
6151 authentication. Affected file lib/silccore/silcauth.[ch].
6153 * Added `hash' field to the SilcIDListData structure. It is the
6154 hash negotiated in the SKE protocol. Affected file is
6157 * Slight redesigning of the SilcAuthPayload handling routines.
6158 Do not send SilcPKCS but SilcPublicKey as argument.
6160 * Implemented the public key authentication support to the
6161 serverconfig. The public key is loaded from the provided path
6162 and saved as authentication data to void * pointer. Thus,
6163 changed the unsigned char *auth_data to void *auth_data;
6165 * Fixed SHUTDOWN command to send the reply before the server
6166 is shutdown. :) Affected file silcd/command.c.
6168 * Fixed fatal bug in CONNECT command. The hostname was invalid
6169 memory and server crashed. Affected file silcd/command.c.
6171 * Fixed fatal bug in CLOSE command. The server_entry became
6172 invalid but was referenced later in the command. Affected file
6175 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6177 * Fixed fatal bug in failure packet handling. Server ignored
6178 the failure and thus crashed when it came.
6182 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6184 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
6185 that the command may be executed only once in (about) 2 seconds.
6186 The old SILC_CF_LAG flag is same but allows command bursts up
6187 to five before limiting.
6189 Added the support for CF_LAG and CF_LAG_STRICT flags to the
6190 server code. Various commands now includes the CF_LAG_STRICT
6191 flag to disallow any kind of miss-use of the command.
6193 * Fixed the silc_buffer_unformat to not to allocate any data
6194 if the length of the data is zero. It used to allocate the
6195 length + 1. Affected file lib/silcutil/silcbuffmt.c.
6197 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6199 * Changed the format of AdminConnection configuration section
6200 in the server. Added username of the admin to the format.
6201 Affected files silcd/serverconfig.[ch].
6203 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
6204 to return admin configuration data by host, username and/or
6207 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6209 * Implemented WHOWAS command to the server. Added the functions:
6211 silc_server_command_whowas_parse,
6212 silc_server_command_whowas_send_reply,
6213 silc_server_command_whowas_from_client and
6214 silc_server_command_whowas_from_server
6216 * Added <Client ID> argument to the WHOWAS command reply. Updated
6217 the protocol specs accordingly.
6219 * Implemented WHOWAS command and command_reply to the client
6222 Implemented the WHOWAS printing on the user interface.
6224 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6226 * Added new argument to the WHOWAS command reply, the real name.
6227 It is an optional argument. Updated the protocol specs.
6229 * Added SilcIDCacheDestructor callback that is registered when
6230 the SilcIDCache is allocated. The callback is called when
6231 an cache entry in the ID Cache expires, or is purged from the
6232 cache. Added into lib/silccore/idcache.[ch].
6234 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
6235 to destruct the client entries when the cache entry expires.
6236 Other ID Cache's in server and in the client library ignores
6239 * If the ID Cache entry's `expire' field is zero then the entry
6240 never expires. Added boolean `expire' argument to the
6241 silc_idcache_add function in the lib/silccore/idcache.[ch].
6242 If it is TRUE the default expiry value is used.
6244 * Added silc_server_free_client_data_timeout that is registered
6245 when client disconnects. By default for 5 minutes we preserve
6246 the client entry for history - for WHOWAS command.
6248 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6250 * Added support to the server to enforce that commands are not
6251 executed more than once in 2 seconds. If server receives
6252 commands from client more frequently, timeout is registered
6253 to process the commands. Affected file silcd/command.c.
6254 Added new function silc_server_command_process_timeout.
6256 * Changed NICK_NOTIFY handling in client library to check that
6257 if the client's nickname was changed, so there is no need to
6258 resolve anything from the server.
6260 * Removed error printing from the WHOIS and IDENTIFY commands.
6261 If error occurs then it is ignored silently in the client library.
6262 The application, however, may map the received error to
6263 human readable error string. The application currently maps
6264 the NO_SUCH_NICKNAME error to string.
6266 * Made the command status message public to the application. Moved
6267 them from lib/silcclient/command_reply.c to
6268 lib/silcclient/command_reply.h. The application can map the
6269 received command status to the string with the
6270 silc_client_command_status_message function.
6272 * Added check to the server to check that client's ID is same
6273 as the Source ID in the packet the client sent. They must
6276 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6278 * Added dist-bzip hook to the Makefile.am to make bzip2
6279 compressed distributions.
6281 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6283 * Server now enforces the maximum length for the nickname and
6284 the channel as protocol specification dictates. 128 bytes for
6285 nickname and 256 bytes for channel name.
6287 * Moved the WHOIS printing to the application. The client libary
6288 does not print out the WHOIS information anymore, the application
6289 must do it. Renamed silc_client_command_reply_whois_print to
6290 the silc_client_command_reply_whois_save.
6292 The client's idle time is also sent to the application now, and
6293 the idle is shown on screen.
6295 * Added silc_client_command_reply_identify_save to save the
6296 received IDENTIFY entries.
6298 * Do not check for channel private keys in message sending and
6299 reception if the channel does not have the PRIVKEY mode set.
6300 Affected file lib/silclient/client_channel.c.
6302 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6304 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
6305 just surfaced after chaning the JOIN procedure.
6307 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6309 * Added silc_client_get_clients_by_list to get client entries
6310 from Client ID list, that is returned for example by JOIN
6311 and USERS command replies. The application should use this
6312 function for example when JOIN command reply is received to
6313 resolve the clients already on the channel (library does not
6314 do that anymore as USERS command reply is not used in the JOIN
6315 procedure anymore). Affected files lib/silcclient/silcapi.h and
6316 lib/silcclient/idlist.c.
6318 * JOIN command reply and USERS command reply returns now SilcBuffer
6319 pointers instead of unsigned char pointers when returning
6320 the client list and mode list.
6322 * Added <Client ID> argument to the JOIN command reply, mainly
6323 for the server to identify for which client the command was
6324 originally sent. Updated protocol specs accordingly.
6326 * Added SilcDlist private_key pointer to the SilcChannelEntry
6327 in the client to support the channel private keys. Affected
6328 file is lib/silcclient/idlist.h.
6330 * Added SilcChannelPrivateKey argument to the function
6331 silc_client_send_channel_message so that application can choose
6332 to use specific private ke if it wants to. If it is not provided,
6333 the normal channel key is used, unless private keys are set.
6334 In this case the first (key that was added first) is used
6335 as the encryption key.
6337 * Implemented the support for channel private key handling.
6338 Implemented the following functions:
6340 silc_client_add_channel_private_key,
6341 silc_client_del_channel_private_keys,
6342 silc_client_del_channel_private_key,
6343 silc_client_list_channel_private_keys and
6344 silc_client_free_channel_private_keys
6346 Affected file lib/silcclient/client_channel.c.
6348 * Added the support for the private keys in the channel message
6349 sending and encryption and in the message reception and
6350 decryption. Affected funtions are
6351 silc_client_send_channel_message and silc_client_channel_message.
6353 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6355 * Added SKE's key verify callback to the client library's
6356 KE protocol context. Affected files lib/silcclient/protocol.[ch].
6358 * Removed the statement that server (or router) must send USERS
6359 command reply when joining to the channel so that the client
6360 knows who are on the channel. Instead, the client list and
6361 client's mode list is now sent in the JOIN command reply to the
6362 client who joined channel. This is better solution.
6364 * Added function silc_server_get_users_on_channel and function
6365 silc_server_save_users_on_channel to the silcd/server.[ch].
6367 * Removed function silc_server_command_send_users from the
6370 * Do not show topic on the client library anymore. The topic is
6371 sent in the command reply notify to the application and the
6372 application must show the topic now.
6374 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6376 * Added client searching by nickname hash into the IDENTIFY and
6377 WHOIS commands in the server as they were clearly missing from
6378 them. Affected file is silcd/command.c.
6380 * Fixed a bug in private message receiving in the client library.
6381 The remote ID was freed and it wasn't supposed, now it is
6384 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6386 * Minor fix to the channel payload; allocate the data area, as it
6387 needs to be of specific length.
6389 * If the key agreement port is zero then the operating
6390 system will define the bound port. Affected files are
6391 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
6393 * Added new function silc_channel_payload_decrypt into the file
6394 lib/silccore/silcchannel.[ch].
6396 * Moved the channel message etc, check from silc_packet_decrypt
6397 to applications. The library calls now a generic
6398 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
6399 when the packet is either normal or special. This was done to
6400 allow more wide range of checking that was not allowed when
6401 the code was in library. Now applications can do virtually any
6402 checks to the packet and return to the library the decision how
6403 the packet should be processed. Affected files are
6404 lib/silccore/silcpacket.[ch].
6406 Added silc_server_packet_decrypt_check to the server and
6407 silc_client_packet_decrypt_check to the client library.
6409 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
6410 to send with specified source and destination information.
6412 * Channel message delivery between routers was broken after the
6413 channel key distribution was fixed earlier. The channel key
6414 was used be to distributed to other routers as well which is not
6415 allowed by the protocol. Now this is fixed and channel keys
6416 really are cell specific and the channel message delivery between
6417 routers comply with the protocol specification.
6419 * Fixed various commands in server to check also the global list
6420 for the channel entry and not just the local list. The affected
6421 file silcd/command.c.
6423 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6425 * Added assert()s to buffer formatting and unformatting routines
6426 to assert (if --enable-debug) when error occurs. Affected
6427 file: lib/silcutil/silcbuffmt.c.
6429 * Changed to auto-reconnect to check whether the remote host is
6430 router and register the re-connect timeout if it is. It used
6431 to check that whether we are normal server, but router must do
6432 auto-reconnect with another router as well. Affected file
6435 * Removed the [<key len>] option from CMODE command as the cipher
6436 name decides the key length, nowadays. See the defined ciphers
6437 from the protocol specification.
6439 * Added [<hmac>] option to the CMODE command to define the HMAC
6440 for the channel. Added SILC_CMODE_HMAC channel mode.
6442 * Added [<hmac>] option for the JOIN command so that user can
6443 select which HMAC is used to compute the MACs of the channel
6446 * Added Hmac field to the Channel Message Payload. The integrity
6447 of plaintext channel messages are now protected by computing
6448 MAC of the message and attaching the MAC to the payload. The
6449 MAC is encrypted. Now, it is clear that this causes some
6450 overhead to the size of the packet but rationale for this is that
6451 now the receiver can verify whether the channel message decrypted
6452 correctly and also when private keys are set for the channel the
6453 receiver can decrypt the packet with several keys and check from
6454 the MAC which key decrypted the message correctly.
6456 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
6457 lib/silccrypt/silccipher.[ch].
6459 * Added silc_hash_len to return the digest length into the
6460 lib/silcrypt/silchash.[ch].
6462 * Rewrote parts of Silc Channel Payload interface in the
6463 lib/silccore/silcchannel.[ch]. The encode function now also
6464 encrypts the packet and parse function decrypts it.
6466 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6468 * Fixed a minor formatting bug in the SKE's key material processing.
6469 It actually might have processed the keys wrong way resulting
6472 * Redefined the mandatory HMAC algorithms and added new algorithms.
6473 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
6474 and hmac-md5 truncated to 96 bits. The mandatory is now
6475 hmac-sha1-96. Rest are optional (including the one that used
6476 to be mandatory). Rationale for this is that the truncated HMAC
6477 length is sufficient from security point of view and can actually
6478 make the attack against the HMAC harder. Also, the truncated
6479 HMAC causes less overhead to the packets. See the RFC2104 for
6482 * Added new [hmac] configuration section. The SKE used to use
6483 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
6484 is of course wrong. The official names that must be proposed in
6485 the SKE are the ones defined in the protocol specification
6486 (hmac-sha1-96 for example). The user can configure any hmac
6487 using any hash function configured in the [hash] section. At
6488 least, the mandatory must be configured.
6490 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
6492 * Added HMAC list to the SKE proposal list. It has now both
6493 hash algorithm list and HMAC list. This makes the protocol
6494 incompatible with previous versions. The SKE now seems to work
6495 the way it is supposed to work, for the first time actually.
6497 * Defined plain Hash algorithms to the protocol specification.
6500 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6502 * Implemented support for key agreement packets into the server.
6503 Added functions silc_server_key_agreement and
6504 silc_server_send_key_agreement. Other than these functions,
6505 server has nothing to do with this packet.
6507 * Added support for private message key packets into the server.
6508 Added functions silc_server_private_message_key and
6509 silc_server_send_private_message_key.
6513 * Changed the silc_[client|server]_protocol_ke_set_keys to be
6514 called in the protocol's final callback instead in the END
6515 protocol state. This makes a little more sense and in the same
6516 time in client we can use the same protocol routines for normal
6517 key exchange and to key agreement packet handling as well.
6519 * Added to both client's and server's KE protocol context the
6520 SilcSKEKeyMaterial pointer to save the key material. We will
6521 bring the key material to the protocol's final callback by doing
6522 this. The final callback must free the key material.
6524 * Added SKE's packet_send callback into client's KE protocol
6525 context so that the caller can choose what packet sending function
6526 is used. This way we can use different packet sending when
6527 doing normal SKE when doing key agreement packet handling (in
6528 the key agreement packet handling we do not want to encrypt
6531 * Implemented the responder side of the key agreement routines
6532 in the client. The client can now bind to specified port and
6533 accept incoming key negotiation. The key material is passed
6534 to the application after the protocol is over.
6536 * Implemented the processing of incoming Key Agreement packet
6537 in the client. Added function silc_client_key_agreement to
6540 * Implemented the intiator side of the key agreement routines
6541 in the client. The client can now initiate key agreement with
6542 another remote client. The key material is passed to the
6543 application after the protocol is over.
6545 * Created client_keyagr.c to include all the key agreement
6548 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
6549 SILC_TASK_CALLBACK except that it is not static.
6551 * Created client_notify.c and moved the Notify packet handling
6552 from the client.[ch] into that file.
6554 * Created client_prvmsg.c and moved all private message and
6555 private message key routines from the client.[ch] into that file.
6557 * Create client_channel.c and moved all channel message and
6558 channel private key routines from the client.[ch] into that file.
6560 * Changed silc_client_get_client_by_id_resolve to resolve with
6561 WHOIS command instead of IDENTIFY command, in the file
6562 lib/silclient/idlist.c.
6564 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6566 * Implemented the SKE's responder side to the Client library.
6568 * When FAILURE is received to the protocol do not trust it
6569 blindly. Register a timeout to wait whether the remote closes
6570 the connection as it should do it, only after that process the
6571 actual failure. This was changed to both client and server.
6573 * Added client_internal.h to include some of the structures
6574 there instead of client.h in lib/silcclient/.
6576 * Added function silc_task_unregister_by_callback to unregister
6577 timeouts by the callback function.
6579 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6581 * Some "Incomplete WHOIS info" errors has been appearing on the
6582 log files. Took away the entry->userinfo check from WHOIS
6583 reply sending. The entry->userinfo is now " " if client did not
6584 provide one. I thought this was fixed earlier but something
6585 is wrong still. Let's see if the error still appears.
6587 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6589 * Fixed a minor bug in the login when the channel key is
6590 re-generated in the server. It used to generate the key in
6591 wrong order and thus caused problems in the channel traffic.
6593 * Fixed a minor bug in channel key distsribution after
6594 KICK command. The key was not sent to the router even though
6597 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6599 * Added silc_ske_process_key_material_data as generic routine
6600 to process any key material as the SILC protocol dictates. The
6601 function is used by the actual SKE library but can be used by
6602 applications as well. This relates to the private message keys
6603 and the channel private keys since they must be processed the
6604 same way the normal SILC session keys. The protocol dictates
6605 this. Affected files: lib/silcske/silcske.[ch].
6607 Added also silc_ske_free_key_material to free the
6608 SilcSKEKeyMaterial structure.
6610 * Defined silc_cipher_set_key function to set the key for
6611 cipher without using the object's method function. The affected
6612 files: lib/silccrypt/silccipher.[ch].
6614 * Implemented silc silc_client_add_private_message_key,
6615 silc_client_add_private_message_key_ske,
6616 silc_client_del_private_message_key,
6617 silc_client_list_private_message_keys and
6618 silc_client_free_private_message_keys functions in the
6621 Added functions silc_client_send_private_message_key to send
6622 the Private Message Key payload and silc_client_private_message_key
6623 to handle incoming Private Message Key payload.
6625 * Added Cipher field to the Private Message Key payload to set
6626 the cipher to be used. If ignored, the default cipher defined
6627 in the SILC protocol (aes-256-cbc) is used.
6629 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6631 * Removed lib/silcclient/ops.h file.
6633 Redefined parts of the SILC Client Library API. Created new
6634 file silcapi.h that deprecates the ops.h file and defines the
6635 published Client Library API. Defined also private message key
6636 API and channel private key API into the file.
6638 This is the file that the application must include from the
6639 SILC Client Library. Other files need not be included by
6640 the application anymore.
6642 * Added new key_agreement client operation callback and also
6643 defined the Key Agreement library API for the application.
6645 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6647 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
6648 is used by clients to request key negotiation between another
6649 client in the SILC network. If the negotiation is started it
6650 is performed using the SKE protocol. The result of the
6651 negotiation, the secret key material, can be used for example
6652 as private message key.
6654 Implemented the Key Agreement payload into the files
6655 lib/silccore/silauth.[ch].
6657 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6659 * Redefined ciphers for the SILC protocol. Added some new ciphers
6660 and defined the key lengths for the algorithms. Changed the
6661 code accordingly. The default key length is now 256 bits.
6663 * Fixed SKE key distribution function silc_ske_process_key_material
6664 when the key length is more than 128 bits. The default key
6665 length in SILC is now 256 bits.
6667 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
6668 to indicate unsupported algorithm.
6670 * Renamed rijndael.c to aes.c and all functions as well.
6672 * Fixed a long standing channel key setting bug in client library.
6673 Weird that it has never surfaced before.
6675 * Fixed bug in channel deletion. If the entire channel is removed
6676 then it must also delete the references of the channel entry
6677 from the client's channel list as the client's channel entry and
6678 the channel's client entry share same memory.
6680 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6682 * Implemented CONNECT and SHUTDOWN commands in the client.
6684 * Implemented CLOSE command to the client.
6686 * Added the function silc_idlist_find_server_by_name into the
6687 files silcd/idlist.[ch].
6689 Added the function silc_idlist_find_server_by_conn into the
6690 files silcd/idlist.[ch].
6692 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6694 * DIE command was renamed to SHUTDOWN. Updated the both code
6697 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
6698 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
6700 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
6703 * Added function silc_server_create_connection function to create
6704 connection to remote router. My server implementation actually
6705 does not allow router to connect to normal server (it expects
6706 that normal server always initiates the connection to the router)
6707 so the CONNECT command is only good for connecting to another
6710 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6712 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
6713 or some other client was kicked from the channel.
6715 Implemented the handling of the notify type to both client
6718 Implemented silc_server_send_notify_kicked to send the KICKED
6719 notify. It is used to send it to the server's primary router.
6721 * Implemented the KICK command into server and client.
6723 * Added `query' argument to the silc_idlist_get_client function
6724 to indicate whether to query the client from server or not if
6727 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
6728 to indicate that the client is not channel founder.
6732 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6734 * Removed the rng context from SilcPacketContext structure and
6735 changed that the packet routine uses the Global RNG API.
6737 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6739 * Added support for quit message that client can "leave" on the
6740 channel when it quits the SILC. It is ditributed inside the
6741 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6743 Added silc_server_free_client_data that will take the
6744 signoff message as argument.
6746 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6748 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6750 * Updated parts of the protocol specification to keep it up
6753 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6755 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6756 payloads in one packet.
6758 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6759 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6760 use now the new List flag.
6762 * Also deprecated the following packet types: REPLACE_ID,
6763 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6765 * Added list support for Notify packet in server.
6767 * Added silc_server_send_notify_channel_change to send the
6768 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6769 the silc_server_send_replace_id.
6771 * Added silc_server_send_notify_nick_change to send the
6772 NICK_CHANGE notify type. Deprecates the function
6773 silc_server_send_replace_id.
6775 * Added silc_server_send_notify_join to send the JOIN notify type.
6776 Deprecates the function silc_server_send_new_channel_user.
6778 * Added silc_server_send_notify_leave to send LEAVE notify type.
6779 Deprecates the function silc_server_send_remove_channel_user.
6781 * Added silc_server_send_notify_cmode and
6782 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6783 types. Deprecates the silc_server_send_set_mode function.
6785 * Added SERVER_SIGNOFF notify type to indicate that server has
6786 quit. This means that all clients on the channel from that
6787 server will drop. This can be also used when netsplit happens.
6789 Deprecated REMOVE_ID packet type since it is not needed anymore
6792 Added silc_server_send_notify_server_signoff to send the
6793 SERVER_SIGNOFF notify type. Deprecates the function
6794 silc_server_send_remove_id.
6796 Added also silc_server_send_notify_signoff to send the
6797 SIGNOFF notify type.
6799 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6800 SILC protocol from this day on. Changed the protocol
6801 specification as well.
6803 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6804 notify type. It is used between routers to notify about
6805 topic changes on a channel.
6807 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6810 * Partly updated the protocol specification to comply with the
6811 changes now made. It is still though a bit outdated.
6813 * The JOIN notify type now takes one extra argument <Channel ID>.
6814 The packet used to be destined to the channel but now the
6815 JOIN type may be sent as list thus it is impossible to
6816 destine it to any specific channel. By adding this argument
6817 it is again possible.
6819 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6821 * Added CREDITS file. The CHANGES and CREDITS file will appear
6822 in the distribution as well.
6824 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6826 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6827 types in the server's silcd/packet_receive.c.
6829 * Implemented CMODE and CUMODE to work in router environment.
6831 * Fixed minor encoding and decoding buglet from the
6832 lib/silccore/silcmode.c.
6834 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6837 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6839 * Changed all SilcConfigServer* and silc_config_server* to
6840 SilcServerConfig* and silc_server_config*, respectively.
6843 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6845 * Associated the ID (client or server ID) to the Authentication
6846 Payload to avoid any possibility of forging. Updated the
6847 protocol specification and the code accordingly.
6849 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6851 * The RSA key length is now save to the RsaKey context in the
6852 key generation process in lib/silccrypt/rsa.c. The key length
6853 is now used to figure out the maximum size of the block allowed
6854 to be encrypted/signed.
6856 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6857 is equivalent to the silc_mp_mp2bin but does not allocate any
6860 * Changed silc_mp_mp2bin API to take length argument. If it is
6861 non-zero then the buffer is allocated that large. If zero, then
6862 the size is approximated using silc_mp_sizeinbase, which however
6865 * Created Global RNG API which is global RNG that application can
6866 initialize. After initializing, any routine anywhere in the
6867 code (including library) can use RNG without allocating a new
6868 RNG object. This was done to allow this sort of use of the
6869 RNG in code that has no chance to allocate RNG object. All
6870 applications currently allocate this and many routines in the
6871 library use this. Affected file lib/silccrypt/silcrng.[ch].
6873 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6874 it to use the Global RNG API.
6876 * Defined Authentication Payload into protocol specification that
6877 is used during SILC session to authenticate entities. It is
6878 used for example by client to authenticate itself to the server
6879 to obtain server operator privileges.
6881 Implemented this payload into the lib/silccore/silcauth.[ch].
6882 Implemented also routines for public key based authentication
6883 as the new protocol specification dictates.
6885 Moved definitions of different authentication methods from
6886 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6888 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6889 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6890 silc_pkcs_verify_with_hash functions into the file
6891 lib/silccrypt/silcpkcs.[ch].
6893 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6895 * The client entry's userinfo pointer must be always valid.
6896 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6897 will fail since it requires the userinfo. Now, the userinfo
6898 is allocated as "" if actual userinfo does not exist. Actually,
6899 it must exist and it is totally Ok to drop client connections
6900 that does not announce the userinfo. However, we will make
6901 this workaround for now.
6903 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6904 to return the remote port by socket.
6906 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6908 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6909 SILC_SERVER_PENDING_EXEC and added an new macro
6910 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6911 data or when error occurs while processing the pending command.
6913 Added new argument `destructor' into silc_server_command_pending
6914 and to the SilcServerCommandPending object. This destructor is
6915 now called after calling the pending callback or if error occurs
6916 immediately. If error occurs the actual pending callback won't
6917 be called at all - only the destructor. The destructor may be
6918 NULL if destructor is not needed.
6920 All this applies for client library code as well. Similar
6921 changes were made there as well for the pending commands.
6923 In the client, the application must now allocate the
6924 SilcClientCommandContext with the silc_client_command_alloc
6927 * Added reference counter to the SilcServerCommandContext. Added
6928 function silc_server_command_alloc and silc_server_command_dup
6931 Same type of functions added to the client library for the same
6934 * Removed the cmd_ident from IDListData away since it is now
6935 global for all connections. It is the command identifier used
6936 in command sending and with pending commands. The affected file
6939 * Added reference counter to the SilcSocketConnection objecet to
6940 indicate the usage count of the object. The object won't be
6941 freed untill the reference counter hits zero. Currently only
6942 server uses this, and client ignores it. The client must be
6943 set to use this too later. The affected files are
6944 lib/silccore/silcsockconn.[ch]. Added also the function
6945 silc_socket_dup to increase the reference counter.
6947 This was mainly added because it is possible that the socket
6948 is removed underneath of pending command or other async
6949 operation. Now it won't be free'd and proper DISCONNECTING
6950 flags, etc. can be set to avoid sending data to connection that
6951 is not valid anymore.
6953 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6954 the connection. After that it sets SILC_SET_DISCONNECTED.
6955 It is, however, possible that the socket data is not still freed.
6956 The silc_server_packet_process now checks that data is not
6957 read or written to connection that is DISCONNECTED. The socket
6958 get's freed when the reference counter hits zero.
6960 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6962 * Changed the client operation API: channel_message operation's
6963 `sender' is now the client entry of the sender, not the nickname
6964 and the `channel' is the channel entry, not the channel name.
6966 In the private_message operation the `sender' is now also the
6967 client entry of the sender not the nickname.
6969 Affected file is lib/silcclient/ops.h and all applications
6970 using the client operations.
6972 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6974 * Moved the calling of ops->connect() from connect_to_server_final
6975 into receive_new_id functin since that is the point when the
6976 client is actually allowed to send traffic to network. The
6977 affected file is lib/silcclient/client.c.
6979 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6981 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6982 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6983 (if needs broadcasting) instead of broadcasting the packets one
6984 by one which would make a burst in the network traffic.
6986 * Added `broadcast' argument to the functions in silcd/server.[ch]
6987 silc_server_create_new_channel[_with_id] to indicate whether
6988 to send New Channel packet to primary router.
6990 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6992 * Added new function into the silcd/server.[ch] files:
6993 silc_server_create_new_channel_with_id to create new channel with
6994 already existing Channel ID.
6996 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6997 lib/silccore/silcpacket.h. This packet is used t send list of
6998 Set Mode payloads inside one packet. Server uses this to set
6999 the modes for the channels and clients on those channels, that it
7000 announced to the router when it connected to it. The protocol
7001 specification has been updated accordingly.
7003 * The silc_server_new_channel did not handle the packet coming
7004 from normal server as it normally does not send that. However,
7005 when it announces its channels it does send it. Implemented
7006 the support for that.
7008 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
7009 into the file lib/silccore/id.h.
7011 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7013 * Fixed memory leaks in the functions silc_idlist_del_client,
7014 silc_idlist_del_channel and silc_idlist_del_server in the file
7015 silcd/idlist.c. All of those leaked like a sieve.
7017 * Fixed some small memory leaks in the client's function
7018 silc_client_notify_by_server.
7020 * Added functions into silcd/server.c: silc_server_announce_clients,
7021 silc_server_announce_channels and silc_server_announce_server.
7022 These functions are used by normal and router server to announce
7023 to its primary router about clients, channels and servers (when
7024 router) that we own. This is done after we've connected to the
7027 These functions effectively implements the following packet types:
7028 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
7029 and SILC_PACKET_NEW_ID_LIST.
7031 * Added new functions into the silcd/packet_receive.[ch]:
7032 silc_server_new_id_list, silc_server_new_channel_list and
7033 silc_server_new_channel_user_list to handle the incoming
7034 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
7036 * Added support of changing Channel ID in the function
7037 silc_server_replace_id. If the server that announces a channel
7038 to the router already exists in the router (with same name but
7039 with different Channel ID), router is responsible to send
7040 Replace ID packet to the server and force the server to change
7041 the Channel ID to the one router has.
7043 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
7044 client that the Channel ID has been changed by the router. The
7045 normal server sends this to the client. Client must start using
7046 the new Channel ID as the channel's ID.
7048 Implemented handling of this new type into lib/silcclient/client.c
7049 into the function silc_client_notify_by_server.
7051 * Added new function silc_idlist_replace_channel_id into the files
7052 silcd/idlist.[ch] to replace the Channel ID.
7054 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7056 * Call silc_server_command_identify_check always when processing
7057 the IDENTIFY command in silcd/command.c
7059 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7061 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
7062 send keepalive packets. The packet can be sent by clients,
7063 servers and routers.
7065 Added function silc_socket_set_heartbeat into the file
7066 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
7067 If not set, the heartbeat is not performed. The actual
7068 heartbeat is implemented in the low level socket connection
7069 library. However, application is responsible of actually
7072 Added silc_server_send_heartbeat to send the actual heartbeat
7073 packet into silcd/packet_send.[ch]. Server now performs
7074 keepalive with all connections.
7076 * Added silc_task_get_first function into lib/silcutil/silctask.c
7077 to return the timeout task with shortest timeout. There was a bug
7078 in task unregistration that caused problems. TODO has been
7079 updated to include that task system must be rewritten.
7081 * The client library will now resolve the client information when
7082 receiving JOIN notify from server for client that we know but
7083 have incomplete information.
7085 * Rewrote parts of silc_server_remove_from_channels and
7086 silc_server_remove_from_one_channel as they did not remove the
7087 channel in some circumstances even though they should've.
7089 * Encryption problem encountered in server:
7091 The LEAVE command used to send the Channel Key packet to the
7092 router immediately after generating it. However, the code
7093 had earlier sent Remove Channel user packet but not immediately,
7094 ie. it was put to queue. The order of packets in the router
7095 was that Channel Key packet was first and Remove Channel User
7096 packet was second, even though they were encrypted in the
7097 reverse order. For this reason, MAC check failed. Now, this
7098 is fixed by not sending the Channel Key packet immediately but
7099 putting it to queue. However, this is more fundamental problem:
7100 packets that are in queue should actually not be encrypted
7101 because packets that are sent immediately gets encrypted
7102 actually with wrong IV (and thus MAC check fails). So, packets
7103 that are in queue should be encrypted when they are sent to
7104 the wire and not when they put to the queue.
7106 However, the problem is that the current system has not been
7107 designed to work that way. Instead, the packet is encrypted
7108 as soon as possible and left to the queue. The queue is then
7109 just purged into wire. There won't be any fixes for this
7110 any time soon. So, the current semantic for packet sending
7113 o If you send packet to remote host and do not force the send
7114 (the packet will be in queue) then all subsequent packets to the
7115 same remote host must also be put to the queue. Only after the
7116 queue has been purged is it safe again to force the packet
7119 o If you send all packets immediately then it safe to send
7120 any of subsequent packets through the queue, however, after
7121 the first packet is put to queue then any subsequent packets
7122 must also be put to the queue.
7124 Follow these rules and everything works fine.
7126 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7128 * Added new function silc_server_remove_clients_by_server to
7129 remove all client entries from ID list when the server connection
7130 is lost. In this case it is also important to invalidate all
7131 client entires as they hold the invalid server entry. This
7132 fixes fatal bug when server has lost connection and will reconnect
7135 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7137 * Made some sanity checks to silc_server_daemonise like to check
7138 whether the requested user and group actually exists.
7140 * Added sanity check to SKE's silc_ske_responder_finish to check
7141 that the public and private key actually is valid.
7143 * Invalidate the client's nickname when receiving Replace ID
7144 packet and the Client ID is being replaced. This means that the
7145 server will query the nickname if someone needs it (client)
7148 * Sort the ID Cache in client library when the ID Cache data
7149 has changed (needs sorting).
7151 * Do not allow for SILC client to create several connections to
7152 several servers. The client does not support windows right now
7153 and generating multiple connections causes weird behaviour.
7155 Irssi-silc client does support windows and can handle several
7156 connections without problems, see: www.irssi.org and SILC plugin.
7158 * Fixed some places where client was added to the IDList. The
7159 rule of thumb is following (in order to get everything right):
7160 If the client is directly connected local client then the
7161 `connection' argument must be set and `router' argument must be
7162 NULL to silc_idlist_add_client function. If the client is not
7163 directly connected client then the `router' argument must
7164 bet set and the `connection' argument must be NULL to the
7165 silc_idlist_add_client function.
7167 * The funtion silc_server_packet_send_local_channel actually did
7168 not check whether the client was locally connected or not. It
7169 does that now. Fixed a bug related to LEAVE command.
7171 * Fixed Remove Channel User payload parsing bug in server's
7172 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
7174 * The server's silc_server_save_channel_key now checks also the
7175 global ID list for the channel as it might not be in the local
7176 list. Fixed a bug related to LEAVE command.
7178 * Is this the end of the [<unknown>] buglet that has been lurking
7179 around for a long time? A little for loop fix in server's
7180 silc_server_command_whois_parse that is used by both IDENTIFY
7181 and WHOIS command. At least, this was a clear bug and a cause
7182 of one type of [<unknown>] buglet.
7184 * WHOIS and IDENTIFY commands call the function
7185 silc_server_command_[whois/identify]_check function even if
7186 we are not router server.
7188 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7190 * Added --with-gmp configuration option. If set the GMP
7191 is always compiled in the SILC source tree. If not set then
7192 it is checked whether the system has the GMP3 installed. If
7193 it has then the GMP won't be compiled (the system's headers
7194 and library is used), if it doesn't have it then the GMP is
7195 compiled in the SILC source tree.
7197 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7199 * Changed RSA private exponent generation to what PKCS #1
7200 suggests. We try to find the smallest possible d by doing
7201 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
7202 not security fix but optimization.
7204 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7206 * Added new config entry [Identity] to fork the server and run
7207 it as specific user and group. A patch from Bostik.
7209 * Imported Dotconf configuration library into lib/dotconf.
7210 This will be used to create the SILC configuration files later.
7211 It will appear in the distsribution after this commit.
7213 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7215 * A big code auditing weekend happening. Auditing code for
7216 obvious mistakes, bugs and errors. Also, removing any code
7219 Removed files for being obsolete:
7221 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
7222 inline in the file lib/silcutil/silcbuffer.h)
7224 o lib/silcutil/silcbufutil.c (the header has inline versions)
7226 Changed code to fix possible error conditions:
7228 o The buffer formatting routines now check that the destination
7229 buffer really has enough space to add the data. This applies for
7230 both buffer formatting and unformatting
7231 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
7232 unformatting was changed to accomodate following rules:
7233 XXX_*STRING_ALLOC will allocate space for the data into the pointer
7234 sent to the function while XXX_*STRING will not allocate or copy
7235 the data into the buffer. Instead it sets the pointer from the
7236 buffer into the pointer sent as argument (XXX_*STRING used to
7237 require that the pointer must be allocated already). This change
7238 makes this whole thing a bit more consistent and more optimized
7239 (note that the data returned in the unformatting with XXX_*STRING
7240 must not be freed now). The routines return now -1 on error.
7242 o Tried to find all code that use buffer_format and buffer_unformat
7243 and added return value checking to prevent formatting and
7244 especially unformatting errors and possible subsequent fatal
7247 o Changed ske->x and ske->KEY to mallocated pointers in
7248 lib/silcske/silcske.h. Fixed possible data and memory leak.
7250 o Added return value checking to all *_parse* functions. Fixed
7251 many memory leaks as well.
7253 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
7254 so that buffer overflows would not happen. All code now also
7255 checks the return value as it can fail.
7257 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7259 * Added reconnection support to server if the normal server looses
7260 its connection to the router (for example if router is rebooted).
7261 The server performs normal reconnection strategy implemented
7262 to the server. Affected file silcd/server.c.
7264 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7266 * Added new packet type SILC_PACKET_SET_MODE that is used to
7267 distribute the information about changed modes (for clients,
7268 channels and clients channel modes) to all routers in the
7269 network. Updated the protocol specification accordingly.
7271 Added functions into silcd/packet_send.c and
7272 silcd/packet_receive.c: silc_server_send_set_mode,
7273 silc_server_set_mode.
7275 Added new files silcmode.[ch] into lib/silccore that implements
7276 the encoding and decoding of Set Mode Payload. Added new type
7277 SilcSetModePayload. Moved the definitions of different modes
7278 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
7280 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7282 * Oops, a little mistake in server's connection authentication
7283 protocol. The protocol is not ended with FAILURE but with
7284 SUCCESS if the authentication is Ok. :) Affected file is
7287 * Implemented NICK_CHANGE notify handling in server in the file
7288 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
7289 the local clients on the channel. After the changing nickname
7290 in router environment snhould work and the [<unknown>] nickname
7291 should appear no more.
7293 The silc_server_replace_id function that receives the Replace ID
7294 payload now sends the NICK_CHANGE notify type also in the file
7295 silcd/packet_receive.c
7297 * Changed WHOIS and IDENTIFY command to support the maximum amount
7298 of arguments defined in protocol specs (3328 arguments). This
7299 fixed a bug that caused problems when there were more than three
7302 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7304 * Added extra parameter, command identifier, to the
7305 silc_client_send_command so that explicit command identifier
7308 Changed that ID list routines uses specific command identifier
7309 when sending WHOIS/IDENTIFY requests to the server so that they
7310 can be identified when the reply comes back.
7312 Affected files lib/silcclient/command.[ch],
7313 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
7315 * Added `sender' argument to silc_server_packet_send_to_channel
7316 to indicaet the sender who originally sent the packet to us
7317 that we are now re-sending. Ignored if NULL. Affected file
7318 silcd/packet_send.[ch].
7320 * Added some server statistics support in silcd/server_internal.h
7321 SilcServerStatistics structure and around the server code. Also
7322 send some nice statistics information when client is connecting
7325 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7327 * Fixed channel ID decoding in server's JOIN command reply in
7328 silcd/command_reply.c
7330 * Fixed braodcasting of replace ID payload to not to send it if
7331 we are standalone server in silcd/packet_receive.c.
7333 * Fixed all channel message sending routines to not to send
7334 packets to clients that has router set, since they are routed
7335 separately in the same function earlier. Affects file
7336 silcd/packet_send.c and all channel packet sending functions.
7338 * In USERS reply, res_argv[i] are not allocated, the table
7339 is allocated. Thus changed that free the table, not its
7342 * In server's whois_check and identify_check if the client is
7343 locally connected do not send any WHOIS commands - they are not
7346 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7348 * Fixed some minor bugs in client when sending WHOIS command. The
7349 arguments was in wrong order.
7351 * Removed statis function add_to_channel from server in
7352 silcd/command.c that was previously used with the joining but
7355 * Tested USERS command in router environment successfully with two
7356 routers, two servers and two clients.
7358 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7360 * Reorganized the USERS command and command reply in client library
7361 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
7362 When the command is given by user we register a pending command
7363 callback that will reprocess the command after the reply has been
7364 received from the server. When reprocessing the packet we then
7365 display the information. Thus, the USERS information is displayed
7366 now in the command callback instead of in the command reply
7367 callback. The processing of the command is same as previously
7368 when server has sent the command reply in the JOINing process.
7370 * Added to USERS command in silcd/command_reply.c to join the client,
7371 we didn't use to know about, to the channel after we've created
7372 a client entry for it. Also, for clienet we did know already still
7373 check whether it is on the channel or not and add it if not.
7375 * Removed silc_server_command_join_notify as the function and its
7378 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7380 * Changed the client's pending command handling to the same as the
7381 server's pending command handling. It is also now possible to
7382 execute command reply functions from other command reply
7383 function as the function callbacks for commands and command
7384 replies are one and same. The pending commands are not static
7385 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
7386 in client connection context. Thus, pending commands are server
7387 connection specific as it is convenient.
7389 Changed the function silc_client_command_pending and
7390 silc_client_command_pending_del and added new function
7391 silc_client_command_pending_check. Removed the
7392 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
7395 * Added cmd_ident, current command identifier, to the client
7396 connection context in lib/silcclient/client.h to keep track on
7397 command identifiers used in command sending. Client's command reply
7398 function handling now supports the mandatory command identifiers.
7400 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
7401 funtions in client to fully support pending command callbacks.
7403 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
7404 as one of the arguments to the application in the command reply
7407 * NOTE: The FORWARDED flag is depracated. It used to be depracated
7408 before first releasing SILC but came back. Now it is removed again
7409 and should come back nomore. The FORWARDED flag was used only
7410 by the JOINing procedure by forwarding the command packet to router.
7411 Now, the JOINing procedure has been changed to more generic (due
7412 to various router environment issues) and FORWARDED is not needed
7413 anymore for anything. The protocol specification is yet to be
7416 Now, removed silc_server_packet_forward from server and the flag
7417 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
7419 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7421 * Renamed NAMES command to USERS command. The NAMES was named that
7422 due to historical reasons. Now it is renamed. Also, rewrote
7423 parts of the USERS command. The nickname list is not sent anymore
7424 by the server. Only Client ID and mode lists are sent in the USERS
7425 command. Changed this also to the protocol specification.
7427 The client now resolves the names and stuff after it receives
7428 the USERS list from the server when joining to the channel.
7430 * WHOIS and IDENTIFY commands has been changed to support multiple
7431 Client ID's per command. One can now search for multiple users
7432 in the network by sending only one WHOIS or IDENTIFY command.
7433 Changed the code and the protocol specifications.
7435 * Removed silc_server_command_identify_parse and changed that IDENTIFY
7436 uses silc_server_command_whois_parse to parse the request. */
7438 * If normal server, do not parse the WHOIS and IDENTIFY requests
7439 before sending it to the router. Saves some time.
7441 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7443 * Fixed JOIN command on client library. Wrong number of arguments
7444 used to crash the client.
7446 * Added silc_server_channel_has_global function to check whether
7447 channel has global users or not.
7449 * Added silc_server_channel_has_local function to check whether channel
7450 has locally connected clients on the channel.
7452 * The silc_server_remove_from_one_channel now checks whether the
7453 channel has global users or not after given client was removed from
7454 the channel. It also checks whether the channel has local clients
7455 on the channel anymore. If it does not have then the channel entry
7456 is removed as it is not needed anymore.
7458 * The silc_server_notify now checks on JOIN notify whether the joining
7459 client is one of locally connected or global. If it is global then
7460 the channel has now global users on the channel and that is marked
7461 to the channel entry. Also, it now saves the global client to
7462 global list who is joining and JOINs it to the channel. This is
7463 for normal server, that is.
7465 Changed silc_server_send_notify_on_channel,
7466 silc_server_packet_relay_to_channel and
7467 silc_server_packet_send_to_channel check if we are normal server
7468 and client has router set (ie. global client) do not send the
7469 message to that client, as it is already routed to our router.
7471 * Implemented LEAVE notify type handling in silc_server_notify
7474 * Tested LEAVE command in router environment successfully. Tested
7475 with two routers, two servers and two clients.
7479 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
7481 * Implemented SIGNOFF notify type handling in silc_server_notify
7484 * silc_server_remove_id now removes the client entry from all channels
7485 it has joined and thusly sends SIGNOFF notify type.
7487 * Rewrote the NAMES list generation in server by removing two excess
7488 loops. The lists are created now inside one loop.
7490 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7492 * silc_server_remove_channel_user checks now also global list
7493 for channel and client.
7495 * silc_server_new_channel_user checks now both local and global
7496 list for channel and client. Fixed a bug in client id decoding.
7497 Used to decode wrong buffer.
7499 * silc_server_channel_message checks now both local and global
7500 list for channel entry.
7502 * Tested channel joining (hence JOIN) in router environment
7503 successfully. Tested with two routers, two servers and two
7506 * Tested channel message sending in router environment successfully.
7508 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7510 * Added silc_server_save_channel_key into server.[ch] to save the
7511 received channel key in Channel Key payload processing. It is
7512 also used in JOIN command reply handling.
7514 Equivalent function silc_client_save_channel_key added into
7515 client.[ch] into client library.
7517 * Changed JOIN command reply to send information whether the channel
7518 was created or not (is existing already) and the channel key
7519 payload. Changed protocol specs accordingly.
7521 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
7522 the request was sent by ID and not by nickname. Crashed on
7525 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7527 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
7528 now correctly save the received data.
7530 * silc_server_free_sock_user_data now notifies routers in the
7531 network about entities leaving the network.
7533 At the same time implemented functions silc_server_remove_id
7534 and silc_server_send_remove_id to receive and send REMOVE_ID
7535 packets. The packet is used to notify routers in the network
7536 about leaving entities. The ID removed will become invalid in
7539 * Added function silc_idlist_del_server into server. Removes and
7540 free's server entry from ID list.
7542 * silc_server_private_message function now checks, if we are router,
7543 that the destination ID really is valid ID, naturally.
7545 * In router when NEW_ID packet is received (for new client) the
7546 hash of the Client ID is saved in the ID Cache but the
7547 client->nickname is set to NULL, instead of putting the hash
7550 IDENTIFY command now also checks that client->nickname must be
7551 valid. If it is not if will request the data from the server who
7552 owns the client. Added new function
7553 silc_server_command_identify_check.
7555 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
7556 to set the command to already allocated Command Payload.
7558 * Tested private message sending in router environment with two
7559 routers, two servers and two clients. Fixed minor bugs and now
7562 * Fixed segfault from client's NAMES command. Used to crash if
7565 * Forwarded packets must not be routed even if it is not destined
7566 to the receiver. Changed server code comply with this.
7568 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7570 * Added `require_reverse_mapping' boolean value to ServerParams
7571 structure. If TRUE (not default) the server will require that
7572 the connecting host has fully qualified domain name.
7574 If the reverse mapping is not required and hostname could not be
7575 found the IP address is used as hostname.
7577 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7579 * Implemented version string checking to both client and server.
7580 The check is incomplete currently due to the abnormal version
7581 strings used in development version of SILC.
7583 * Changed all command functions in server to use the new
7586 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7588 * Changed char *data to unsigned char *data in ID Cache system to
7589 support binary data as ID Cache data. Changed code to support
7590 binary data in lib/silccore/idcache.c.
7592 * Renamed silc_server_packet_relay_command_reply to
7593 silc_server_command_reply as it is normal packet receiving
7594 function. Rewrote the function to accept command replys for
7595 servers and not only for clients.
7597 * Mark remote router always as registered server if we are connecting
7598 to it. Otherwise, commands sent by the router to us are ignored.
7600 * All ID List find routines now returns the ID Cache Entry pointer
7601 as well if requested.
7603 * WHOIS command works now in router environment, tested with two
7604 routers, two servers and two clients.
7606 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
7607 in router environment (as it is almost equivalent to WHOIS) but
7608 hasn't been tested thoroughly. Added new functions:
7610 silc_server_command_identify_parse
7611 silc_server_command_identify_send_reply
7612 silc_server_command_identify_from_client
7613 silc_server_command_identify_from_server
7615 * Disabled route cache adding because adding two different ID's with
7616 same IP replaces the old cache entry thus giving wrong route.
7617 The entry->router->connection is always the fastest route anyway
7618 so route cache may not be needed. Of course, new routes maybe
7619 established after receiving the ID when the entry->router->connection
7620 might not be anymore the most optimal.
7622 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7624 * Add route cache for received ID for fast routing.
7626 * Added silc_server_packet_route to route received packet on router
7627 that is not destined to us.
7629 * Renamed silc_server_get_route to silc_server_route_get.
7631 * Added id_string and id_string_len fields into SilcServer to
7632 include encoded ServerID for fast comparing without excess
7633 encoding of the ID's.
7635 * Cleaned up WHOIS command on server side. Added following static
7638 silc_server_command_whois_parse
7639 silc_server_command_whois_check
7640 silc_server_command_whois_send_reply
7641 silc_server_command_whois_from_client
7642 silc_server_command_whois_from_server
7644 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
7645 arguments in command replies. All command functions should be
7646 updated to use this macro.
7648 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7650 * Minor typo fixes on command reply handling on server.
7652 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7654 * Added silc_server_command_add_to_channel internal routine to add
7655 the client to the channel after router has created the channel and
7656 sent command reply to the server.
7658 * Added generic silc_server_send_command to send any command from
7661 * Use static buffer with ID rendering instead of duplicating data.
7663 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7665 * Fixed a channel user mode bug when joining to a channel server gave
7666 everybody channel founder rights, oops.
7668 * We mark ourselves as the router of the incoming server connection
7669 if we are router ourselves. This way we can check in some packet
7670 sending functions whether it is locally connected server. For
7671 incoming router connections we put NULL.
7673 * For router sending packets locally means now always sending the
7674 packet cell wide; to local clients and local servers. For normal
7675 server sending packet locally means sending it to only local
7678 * Fixed the JOIN command to really work in router environment. If the
7679 channel is created it is always created by the router. Router is
7680 also responsible of making the initial joining to the channel,
7681 sending JOIN notify to the sending server and distributing
7682 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
7683 does not exist server doesn't do anything else but forward the
7684 command to the router which performs everything.
7686 * Added silc_server_send_channel_key function to send the Channel Key
7689 * Added silc_server_create_channel_key to create new channel key. The
7690 channel key is now re-generated everytime someone joins or leaves
7691 a channel, as protocol dictates. Note: channel->key_len is the
7694 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7696 * Splitted server.[ch] finally. Created now packet_send.[ch] and
7697 packet_receive.[ch] to separate packet sending and receiving
7698 routines. The server.[ch] now includes everything else including
7699 actual packet processing (writing and reading data) and other
7702 Renamed silc_server_private_message_send_internal to
7703 silc_server_send_private_message. The routine is still though
7704 used only to relay private messages as server does not send
7705 private messages itself.
7707 Renamed silc_server_new_channel to silc_server_create_new_channel
7708 and added new function sicl_server_new_channel that handles the
7709 incoming New Channel packet. Added also new sending function
7710 silc_server_send_new_channel to send New Channel Payload.
7712 * Added new function silc_server_notify to process incoming notify
7713 packet to the server/router. Server may then relay the notify
7714 to clients if needed.
7716 * Added new function silc_server_new_channel_user to process incoming
7717 New Channel User packet. Router will redistribute the packet and
7718 send JOIN notify to its local clients and locally connected servers
7719 if needed. Normal server will send JOIN notify to its local client
7720 on same channel when received this packet. Added also corresponding
7721 sending function silc_server_send_new_channel_user to sent the
7724 * Added boolean route argument to send_notif_to_channel and
7725 packet_send_to_channel functions to attempt to route the packet
7726 if it is TRUE and send only locally if it is FALSE.
7728 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7730 * silc_server_replace_id now broadcasts the received replace ID
7731 packet if it is not broadcast packet already. The router must
7732 broadcast to inform other routers about changed ID.
7734 * Added backpointer to server's router into SilcServer context in
7735 silcd/server_internal.h.
7737 * Fixed silc_server_packet_broadcast to send correct broadcast
7740 * The channel key is now distributed to the local client as soon
7741 as it is received from the router (in router environment) so that
7742 no other packet may be sent for the channel until client has
7745 * silc_server_remove_channel_user now broadcasts the received
7746 Remove Channel User packet if it is not broadcast packet already.
7747 The router must broadcast to inform other routers about removed
7750 * Added users field into SilcPacketContext that is a reference count
7751 of the context. One can increase the reference count by calling
7752 silc_packet_context_dup which is now changed to just increase the
7753 reference count instead of duplicating the data. The reference
7754 count is decresed by calling silc_packet_context_free that will
7755 free the data after the reference count hits zero.
7757 For now on the packet context and everything allocated into it
7758 (including the raw packet from network) must be freed by calling
7759 the new silc_packet_context_free function. Added also new function
7760 silc_packet_context_alloc that must be used now to allocate the
7761 context. This also means that if a routine is asynchronous from
7762 silc_[client/server]_packet_parse_type the packet context must
7763 be duplicated by calling silc_packet_context_dup. Otherwise it
7764 gets free'd after silc_[client/server]_packet_parse_type returns.
7765 Also, one must remember that if packet is duplicated then its
7766 reference count must be decresed by calling the free function as
7767 many times as it was duplicated.
7769 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7770 from both client and server.
7772 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7774 * Made joining to a channel working in router environment.
7776 * Cleaned up JOIN command on server side and create function
7777 silc_server_command_join_channel internal routine to make the
7780 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7782 * Changed silc_command_pending list to SilcDList. Also, added
7783 `ident' field to SilcServerCommandPending structure to identify
7784 the reply and to call correct callback.
7786 Added silc_server_command_pending_check function to replace the
7787 corresnponding macro. The silc_command_pending list is not
7790 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7791 to set identifier to previously allocated Command Payload. It
7792 is used to set identifier for command when resending Command
7795 * Added silc_command_payload_encode_payload to encode Command
7796 Payload buffer from SilcCommandPayload structure.
7798 * Added silc_argument_payload_encode_payload to encode Argument
7799 payload buffer from SilcArgumentPayload structure.
7801 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7803 * Changed WHOIS command to support router connection on server side.
7804 The whois request is always sent to router unless the server is
7805 standalone server. After server has received the reply from the
7806 router will it send the reply to the client.
7808 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7809 broadcast received broadcast packet. The function is used only
7810 by router. The broadcast packet is always sent to the router's
7813 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7814 render given ID to printable string, for log files for example.
7816 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7818 * Made basic router to router connections working. At least they
7819 can now connect to each other but nothing really works the way
7820 they are supposed - yet.
7822 * Added new initiator token to RouterConnection configuration
7823 file in silcd/serverconfig.[ch]. It is used to tell whether we
7824 are the initiator to the remote router or whether we'll expect
7825 the other end to connect.
7827 * Moved registering of listener task to silc_server_init, hence
7828 the server starts listenning as soon as it is run, even if it
7829 does not have connections to other routers. Let's see how well
7832 * Changed default connection retry timeouts for more suitable in
7835 * Removed cipher and such arguments from silc_idlist_add_client
7836 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7837 Added new function silc_idlist_add_data to add the keys and stuff
7840 * Added SilcIDListData structure and added it to SilcClientEntry
7841 and SilcServerEntry as their first field in the structure. This
7842 way we can explicitly cast the ID entries to the SilcIDListData
7843 structure and get common data for the entries. In past, we had
7844 to first check what type of connection it is and then cast it to
7845 correct ID entry type. Now, we can directly cast the opaque
7846 pointer to the SilcIDListData (no matter what ID entry it actually
7847 is) and get the data needed.
7849 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7851 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7852 in some circumstances even if threre were timeout tasks, though not
7853 IO tasks, but tasks anyway. Now fixed.
7855 * Defined SilcServerConnection structure to hold connection specific
7856 stuff about directly connected servers and routers. The definition
7857 is currently in silcd/server_internal.h. I thought about having
7858 a bit more important role fro this struct but for now it is used
7859 only when connecting to other server (or router actually).
7861 * Added connecting retry support in server when connecting to
7862 router(s). The retry feature implement exponential backoff
7863 algorithm. Also, added SilcServerParams structure to hold default
7864 parameters for server. For now, it include these retry settings
7865 and are hard coded. After server is moded to be as Silc Server
7866 Library this structure will be more important.
7868 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7870 * Changed client librarys channel->clients table to SilcList and
7871 changed code accordingly.
7873 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7875 * Changed client's channel table to SilcList and changed code
7876 accordingly. Also changed SilcChannelClientEntry to include back-
7877 pointer to the channel so that client entry can use that structure
7878 as list as well and we have fast cross-reference to the channel.
7879 This change dramatically decreased the complexity of channel
7880 handling with client entry and vice versa (removed one extra
7881 loop when searching for channel entry from many functions).
7883 * Changed server->sim from table to SilcDList and changed code
7886 * NAMES command can now be used from user interface. It will show
7887 the user list on the channel, neatly.
7889 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7890 Code now saves realname of the user if it becomes available.
7892 * Renamed configure.in to configure.in.pre and made ./prepare
7893 script to automatically add correct version string to
7894 configure.in which it creates from configure.in.pre.
7896 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7898 * NAMES command reply now shows users mode with the nickname when
7901 * Moved silc_client_ch[u]mode[_char] functions from
7902 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7903 place sucks, they are utility functions and should be in some
7906 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7908 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7911 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7915 * Added TRQ (efficient deque and list library) into lib/trq. This is
7916 a very good list library that is currently used in the SILC. Defined
7917 SilcList API over the library because I didn't like the API very
7918 much. See lib/trq/silclist.h for the API and examples of how to
7919 use the API. Fixed various places in the code to use the new
7920 SilcList API. The SilcList is meant for lists that has a structure
7921 already defined as a list. It is not suitable to add just some
7922 context to the list (in TRQ, the context is the list actually).
7924 So, I defined SilcDList that can be used for the purpose where
7925 predefined list structure does not exit. This can be used as
7926 such list. Now some context just can be added to the SilcDList.
7927 Currently this list is not used in the SILC just yet, though there
7928 are a lot places where this can replace dynamically allocated
7929 tables and I will fix these places, later, to use SilcDList.
7930 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7931 and use TRQ internally).
7933 Also fixed some annoying warning messages that the original TRQ
7934 code generated. Also minor changes to TRQ's Makefile.in.
7936 * Added support for querying by Client ID to both WHOIS and
7937 IDENTIFY commands into server, as required by the protocol.
7939 * Removed method function pointers from SilcBuffer structure. They
7940 weren't used to anything and just increased the context size for
7941 no good reason. This change also made silc_buffer_alloc and
7942 silc_buffer_free functions inline functions.
7944 * Disabled command flooding detection support until it's fixed so
7945 that it accepts commands in but does not execute them more than once
7948 * Added silc_net_localhost(), to return local hostname, into
7949 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7950 that must be initialized before calling silc_client_init.
7952 * Added new function: silc_server_send_notify_on_channels to send
7953 notify messages to all channels client has joined. It is assured
7954 that the message is sent only once per client.
7956 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7957 lib/silcutil/silcutil.[ch] as silc_format function. The new
7958 function is generic and is used by server as well, not only by
7959 the logging routines.
7961 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7962 the provided version string was not acceptable. Added new function:
7963 silc_ske_check_version into lib/silcske/silcske.h. The function
7964 must be implemented by the application (client or server) and it
7965 does not reside in the SKE library. The function checks the version
7966 string remote end sent.
7968 * Added back pointers (to opaque context and to SilcSocketConnection)
7969 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7971 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7972 duplicate packet context structure.
7974 * Changed `notify' client operation to send same arguments as client
7975 receives from server except for ID's. ID's are mapped to correct
7976 ID entry and that is returned. Also, if channel entry is not sent
7977 by server but the notify is for channel the channel entry is sent
7978 to application (otherwise application doesn't know that it is for
7979 channel (library gets it from packet's Destination ID)).
7981 * Added silc_client_remove_from_channels into client library to
7982 remove a client from all channels it has joined to. Used when
7983 received SIGNOFF notify from server. Added also new function
7984 silc_client_replace_from_channels to replace old ID entry with
7985 new ID entry on all channels. Used when received NICK_CHANGE
7988 * Fixed ID Cache list handling in silc_idlist_get_client in
7989 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7990 to get (or query) client by ID.
7992 * Updated TODO list.
7994 * Added connection authentication status message defined by the
7995 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7996 support for these into the code in client and server side.
7998 * Added generic function silc_client_send_command to send any command
7999 with variable argument list. Application should use this function
8000 to send commands if the command functions provided by the library
8001 does not suite for the application's user interface needs.
8003 * Added new `failure' client operation. Application is notified about
8004 received failure packet if client is executing a protocol. In this
8005 case the protocol's execution has failed.
8007 * Added SKE's end notify to send the SKE_SUCCESS notify message that
8008 is required by the protocol.
8010 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
8011 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
8014 * Added status flag to SilcSKE object to indicate realtime status
8015 of the SKE protocol.
8017 * Application receives now exactly same command reply arguments as
8018 the library receives from server. However, if ID is received the
8019 corresponding ID entry is returned to the application (eg. Client
8020 ID is mapped to correct SilcClientEntry entry and that is returned).
8021 Changed command_reply client operation due to this change.
8023 * Changed all ID's in commands and in command replys as ID Payloads.
8024 Change affected both client and server side codes.
8026 All ID's sent in SILC network (with execption of ID's in SILC
8027 Packet header) are sent in ID Payload to support variable length
8030 * Server now notifies nick changes and notifies all clients on
8031 the channels about the new nickname (about the new Client ID,
8034 * Implemented CMODE command to change channel modes. Supports all
8035 channel modes defined by the protocol specs except ban and invite
8036 lists. (Also, private channel key mode is supported but support for
8037 setting private channel key in client is missing, thus, this mode
8038 has no effect on client side (except that server requires that the
8039 client uses private channel key and normal channel traffic does not
8042 Also, invite mode works per se, but INVITE command does not work
8043 yet correctly, so you can set channel as invite only channel but
8044 inviting clients to the channel does not work (it is yet to be
8045 thought what's the best way to do it).
8047 * Added new command SILC_COMMAND_CUMODE to change user mode on the
8048 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
8049 Implemented CUMODE command to change user's mode on the channel.
8050 Supports all modes defined by the protocol specs.
8052 * Added NAMES command reply to return users modes on the channel.
8054 * Removed unnecessary and slow ciphers from lib/silccrypt.
8056 * Set SO_KEEPALIVE option to connection sockets by default.
8058 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
8060 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
8061 redefined the Notify Payload into protocol specs.
8063 * Added silc_id_payload_parse_id to get ID directly from raw
8066 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8068 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
8069 accept searching by Client ID as well.
8071 * Added support for LEAVE and SIGNOFF notify types in client library.
8073 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
8074 to parse ID Payload from raw data.
8076 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8078 * Added flags parameter into silc_ske_assemble_security_properties
8079 function in lib/silcske/silcske.[ch].
8081 * Changed notify client operation to fit better for notify messages
8082 sent by server. The notify payload received from server is now
8083 passed to the application (after parsing it to SilcNotifyPayload).
8084 It is application's responsibility to retrieve the arguments
8085 from the payload and show the message the way it wants. The message
8086 sent by server is implementation specific.
8088 * Changed public keys to comply with the protocol specification.
8089 Old public keys are not supported anymore and are not compatible.
8091 * Removed nickname from Channel Payload as the latest draft removed
8092 it. The client must resolve the nickname from the NAMES command
8093 reply received when it joined the channel.
8095 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
8097 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8099 * Fixed some errors in protocol specification drafts.
8101 * Created lib/silccore/silcnotify.c to implement Notify Payload
8102 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
8103 generic payloads described by protocol specifications. The file
8104 includes implementations for ID Payload and Argument Payload.
8106 * Changed Command Payload implementation to use the new Argument
8107 Payload. Changed command_xxxx_payload to command_payload_xxxx
8108 to comply with SILC coding conventions.
8110 * Added suppport for Argument Payload handling in Notify Payload
8111 implementation as protocol requires it. Added the new support
8112 into server and client lib as well.
8114 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8116 * Added support for multiple nicknames on same channel. [n] is
8117 added locally to the nickname if there are more than one same
8118 nicknames on the channel.
8120 * Server now sends all nicknames that matched WHOIS request.
8121 Client also shows the list received from server.
8123 * Added TOPIC command to client side. User can now set and show
8124 current topic on channel.
8126 * Added MOTD command to client and server. Also, server sends the
8127 motd when client connects to the server.
8129 * Changed version strings to comply ISO 8601.
8131 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8133 * Fixed protocol error handling in client library. It should now
8134 cope even if the SKE fails for some reason.
8136 * Made new protocol specification drafts for submitting to IETF.
8138 * Implemented TOPIC command to server in silcd/command.c.
8140 * Added two new notify types into lib/silccore/silcnotify.h:
8141 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
8142 notify nickname change and topic setting/change on a channel.
8144 * API change of command_reply operation in client library. The
8145 application gets now the status type received from server as well.
8147 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8149 * Removed the function just added to lib/silcutil/silcschedule.[ch].
8151 * Cras fixed and optimized the packet handling even further and
8152 it should work now. Minor change to the prototype of function
8153 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
8155 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8157 * Added new function into lib/silcutil/silcschedule.[ch]:
8158 silc_schedule_with_fd to select() a specified fd. The function
8159 returns after timeout expires or data arrives or goes. The
8160 function is used by packet routines to wait that all data is
8161 received from network.
8163 * Fixed data reading from network in lib/silccore/silcpacket.c.
8164 The code now assures that all data is read from the fd and then
8165 continues packet processing. This was a bug fix since the code
8166 used to drop some data in some circumstances.
8168 * Added new function into lib/silcclient/client.[ch]:
8169 silc_client_start_key_exchange to start key exchange after
8170 connection has been established to server. The code internally
8171 now uses this funtion but its main purpose was to provide it
8172 for applications that perform their own connecting. After
8173 application has created a connection it merely calls this
8174 function to start the key exchange between client and server.
8175 The library takes care of everything else after that.
8177 Updated also lib/silcclient/README to explain the usage of
8180 * Do not send to application information that connection has
8181 been established. Application gets notified it by connect
8184 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8186 * Applied cras's patch to add silc_schedule_one function. The
8187 function runs scheduler once and returns.
8189 * Fixed the scheduler after cras messed it up. The timeout
8190 handling works now as it's supposed to work.
8192 * Added into lib/silccore/ silcnotify.h to include notify
8193 message types support. Changed silc_server_send_notify*
8194 functions, in server.[ch], to support those new notify types.
8195 Added the support for the notify types into client library,
8196 as well. Added new notify client operation into ops.h in
8199 * Changed silc_server_packet_send_to_channel to send normal
8200 packets instead of just channel message packets. The function
8201 is now used to send the notify packets to channels. It is not
8202 used to send channel message packets anymore, as server never
8205 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
8206 va_arg()s as it seems to require it nowadays. I guess, if SILC
8207 is compiled with older va_arg() the new code should work anyway.
8209 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8211 * Splitted core library. Core library (lib/silccore) includes
8212 now only SILC protocol specific core (and common) components.
8213 Created new utility library (lib/silcutil) that includes more
8214 generic purpose stuff. The stuff for util library was taken
8215 from the old core library. This was minor and easy split.
8217 * Created SILC Client Library (lib/silcclient) that includes
8218 implementation of the SILC client without user interface. This
8219 was major move from silc/ directory. The code has been changed
8220 so that it is transparent towards the user interface. The
8221 silc/ directory includes now the same user interface as before
8222 and it uses the new client library. Read lib/silcclient/README.
8223 Basicly, the client library performs everything else related
8224 to SILC except user interface handling. Also, configuration
8225 files are considered to be part of user interface and library
8226 does not handle them.
8228 This change also changed a lot of structures, function naming etc.
8229 Most important change was that SilcClientWindow object was
8230 renamed to SilcClientConnection in the client library. Created
8231 also new file lib/silcclient/ops.h. Also added new files
8232 silc/local_command.[ch] and silc/client_ops.[ch].
8234 All these changes were made to make it easier for user interface
8235 designers to create what ever user interface for the SILC client
8238 It is also expected that the server will be moved to lib
8239 directory as well and SILC Server Library will be created;
8240 sometimes in the future.
8242 * Removed Local commands from lib/silccore/silccommand.h as
8243 they are application specific and new client library does not
8244 handle any of those anymore.
8246 * Several functions moved to lib/silcutil/silcutilc.[ch] from
8247 old client implementation in silc/.
8249 * Added support for callback functions in SILC_LOG_* macros.
8250 Application can now set its own callbacks that will be called
8251 instead of using the default functions that will always print
8252 the debug messages to stderr (or stdout). Also, debugging can
8253 now be disabled by setting silc_debug to FALSE and re-enabled by
8254 setting it to TRUE. Note, that logging will still work even
8255 if debugging is disabled.
8257 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
8258 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
8259 silc_log_reset_debug_callbacks.
8261 * To enable debugging in silc client one must give now -d
8262 option on command line.
8264 * Changed silc_schedule_init to automatically allocate task queues
8265 if they are not allocated before calling it.
8267 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8269 * Added GMP 3.1 into math library.
8271 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8273 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
8274 a channel in SILC network. The packet is used by servers and
8275 routers to notify other routers that user has left a channel.
8276 This little feature was missing until now. Added the feature
8277 to protocol specification as well.
8279 Added functions: silc_server_send_remove_channel_user and
8280 silc_server_remove_channel_user into server.[ch].
8282 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
8283 lib/silccore/silcpacket.h. However, they are not implemented
8286 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8288 * Fixed joining to a channel and sending channel messages
8289 between server and router. The channel message sending should
8290 now work inside a cell.
8292 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8294 * Fixed the private message sending between server and router.
8295 The private message sending should now work inside a cell.
8297 * Added silc_server_replace_id into server.[ch] to replace
8298 existing ID in the SILC network.
8300 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
8301 and silc_idlist_replace_server_id into idlist.[ch] in server.
8303 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8305 * Fixed the server to server connections. Server can again now
8306 connect to router. Router to router connections probably does
8309 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8311 * Added dynamic protocol registering support. Now protocols can
8312 registered and unregistered on the fly. Patch by cras.
8314 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8316 * Added lib/contrib directory to hold routines that some platforms
8317 don't have but are needed by SILC.
8319 * Added getopt.c, getopt1.c and getopt.h from GNU C library
8320 into lin/contrib to provide getopt() and getopt_long() for
8321 those who don't have it.
8323 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8325 * Added AWAY command to client. When away message is set and
8326 client receives a private message packet the client automatically
8327 replies to the sender with the away message.
8329 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
8330 bug seemed to be the cause of recent problems when compiling
8333 * Added version detection support to SKE protocol specification
8334 and added the new changes to the SKE implementation as well.
8335 There were other minor changes in the SKE protocol as well.
8337 Many changes in lib/silcske/silcske.[ch] and in
8338 lib/silcske/payload.[ch].
8340 * Added ^U functionality, clear input line. Patch from cras.
8342 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8344 * Mainly small bugfixes on core library. Fixed some debugging
8345 logging and buffer overflow in silclog.c.
8347 * Updated config.sub and config.guess on the distribution tree.
8349 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8351 * Added command lagging support in server. Client may execute
8352 commands now only once in two seconds.
8354 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8356 * Optimized packet reception. MAC computation and checking is now
8357 also more optimized. A lot previously duplicated code is now
8358 used as generic by both client and server.
8360 * Fixed key pair generation in clientutil.c
8362 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8364 * Added into lib/silccore/silcbufutil.[ch] new function;
8365 silc_buffer_realloc.
8367 * Moved generic packet sending/encryption functions to
8368 lib/silccore/silcpacket.[ch] from client and server. Some
8369 rewriting of the functions.
8371 * Moved all generic packet reception/decryption functions to
8372 lib/silccore/silcpacket.[ch] from client and server. The
8373 packet processing is now much cleaner in both client and server.
8374 These were major changes in both client and server.
8376 * Created many common functions in server to do packet sending.
8377 Previously code were duplicated a lot, this has been removed
8380 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8382 * Rewrote major parts of the ID cache system. Don't know
8383 whether it is better now or not but at least the API is more
8386 * Major rewrite on ID cache stuff on client because of the ID
8387 cache API changes. Added idlist.c to client.
8389 * Also major rewrite on ID cache stuff on server as well.
8390 Major rewrite of idlist.[ch]. SilcXXXList's are now named
8391 SilcXXXEntry's. We won't keep anymore idlist specific pointers
8392 in hand, instead they are all put into the ID cache system now.
8393 All server_idlist_* routines uses ID cache now instead of
8394 traversing its own lists (those lists does not exist anymore).
8395 SilcIDList though still exists. Also, SilcXXXEntry's are
8398 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8400 * Finally made the SKE implementation compliant to the protocol
8401 specification. All mp integers are now binary encoded as
8402 opposed being HEX encoded.
8404 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
8407 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
8408 functions: silc_[encode/decode]_pem. Also added function
8409 silc_encode_pem_file to PEM encode with newlines ('\n') for
8412 * SILC public keys are now encoded either PEM or binary. Same
8413 option is for private keys as well. By default private keys
8414 are binary encoded and public keys PEM encoded. Silly HEX
8415 encoding were removed.
8417 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
8418 function to create fingerprints.
8420 * Fixed a bug in SHA1; does not change the original data anymore.
8422 * Partly implemented INFO command on client and server side.
8423 Fixed CLEAR command. Changes to SERVER command; show current
8424 server(s) when giving command without arguments. Added
8425 VERSION command to client.
8427 * Added check to server that unregistered connections cannot
8428 execute commands (unless it is specificly allowed).
8430 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8432 * Fixed screen refresh.
8434 * Fixed channel joining bug from client. On some circumstances
8435 client tried to join to a channel it had already joined.
8437 * Added public key verification process into client's protocol.c.
8438 The client now verifies the public key from user and saves
8439 it into ~./silc/serverkeys/ directory.
8441 Added into: clientutil.[ch]: silc_client_verify_server_key.
8443 * Changed SKE protocol's silc_ske_initiator_finish function
8444 to accept callback function that verifies the received public
8445 key. Removed old silc_ske_verify_public_key function.
8447 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8449 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
8450 silc_pkcs_private_key[_data]_set.
8452 * Made the password and public authentication more cleaner in
8453 server's protocol.c.
8455 * Removed historic and obsolete protocol `channel_auth' from
8456 both client and server.
8458 * Removed wrong way of sending command status messages from
8459 server to client in server's command.c. The old way violated
8460 protocol specification.
8462 Changes to silccore/silccommand.[ch]: removed
8463 silc_command_encode_status_payload -> not needed anymore,
8464 changed silc_command_encode_payload_va to accept extra
8465 argument on variable argument list. The argument type must
8466 now be provided to the function. Also, added new function:
8467 silc_command_encode_reply_payload_va which is same as
8468 normal command_encode_payload_va except command status type
8469 is provided as extra argument.
8471 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8473 * Added ~./silc directory handling. The directory includes the
8474 public and private keys for the client.
8476 Added silc_client_check_silc_dir, silc_client_create_identifier
8477 and silc_client_load_keys.
8479 * Implemented SILC protocol compliant public key. Added public
8480 and private key saving to and loading from files.
8482 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
8483 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
8484 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
8485 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
8486 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
8488 Implemented: silc_pkcs_save_[public/private]_key[_data] and
8489 silc_pkcs_load_[public/private]_key.
8491 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8493 * Added silc_server_get_route (route.[ch]) to get connection
8494 data for the fastest route for given ID.
8496 * Implemented INVITE command on client and server. The command
8497 were re-defined in the SILC Protocol Specification and the
8498 implementation now complies with the specification.
8500 * Implemented PING command on client and server.
8502 * Implemented NAMES command on client and server. The server side
8503 supports currently only normal server not router server yet.
8504 Some changes to NAMES definition in SILC protocol specification.
8506 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8508 * Implemented LEAVE command on client and server.
8510 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
