524 * Drop root privileges when started in foreground. Don't drop them
525 if debugging also. Affected file is silcd/silcd.c.
527 Mon Apr 8 17:00:41 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
529 * Added more IM-like features by introducing new user modes
530 for setting various presence information. Added new modes:
531 INDISPOSED, BUSY, PAGE, HYPER and ROBOT. Updated protocol
532 specs and code. Protocol TODO #19. Affected files are
533 lib/silccore/silcmode.h, irssi/src/silc/core/client_ops.c,
534 irssi/docs/help/in/umode.in and lib/silcclient/command.c.
536 Sun Apr 7 17:07:59 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
538 * Added STATS command to the protocol after all, to return
539 various statistical information about the network. It can
540 be used by clients to retrieve statistical information, and
541 servers may use it to to fetch cell and network wide
542 statistics from router. Updated the protocol specs and
543 implemented it to the server. Protocol TODO #16.
544 Affected files are lib/silccore/silccommand, silcd/command.[ch],
545 silcd/command_reply.[ch].
547 Sat Apr 6 17:08:58 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
549 * The LIST command reply in client libary now adds new channel
550 entry if the returned channel doesn't exist yet in cache,
551 and returns the channel entry to the application in the
552 command_reply client operation. Affected file is
553 lib/silcclient/command_reply.c.
555 * Changed the channel message payload's MAC generation to
556 include the IV in the MAC as well. This way all relevant
557 parts of the channel message payload are authenticated also
558 with the channel message MAC (and not only by packet MAC).
559 Causes incompatibility with 1.0 protocol. Protocol TODO #7.
560 Affected file is lib/silccore/silcchannel.c.
562 * Fixed the SKE to save the remote version, since the
563 silc_ske_parse_version mistakenly checked wrong version,
564 after it replaced the start payload. Affected files are
565 lib/silcske/silcske.[ch].
567 Fri Apr 5 16:03:03 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
569 * Splitted lib/silcutil/silcutil.h into silcstrutil.h for
570 string utility functions. Added there also new functions
571 silc_utf8_[encode/decode/valid] for UTF-8 string encoding.
572 Affected files lib/silcutil/silcstrutil.[ch].
574 * Renamed silc_*_pem functions to silc_pem_* functions. Affected
575 files are lib/silcutil/silcstrutil.[ch].
577 * Defined that the security property fields in SKE SHOULD be
578 UTF-8 encoded, defined that version string MUST be US-ASCII
579 encoded, defined that passphrases sent in connection
580 authentication protocol MUST be UTF-8 encoded. Implemented
581 these to the client and server. Defined also that other
582 passphrases sent in the protocol MUST be UTF-8 encoded.
583 Affected files are lib/silcske/silcske.c,
584 lib/silcclient/protocol.c, silcd/protocol.c,
585 silcd/serverconfig.c, and lib/silccore/silcauth.c.
587 * Changed the silc_client_close_connection interface to not
588 need the SilcSocketConnection which should not be visible
589 to application. Affected files are lib/silcclient/client.c
590 and lib/silcclient/silcclient.h.
592 * Rewrote the text for Private Message Key Payload in the
593 protocol specification. Protocol TODO #11.
595 Wed Apr 3 16:24:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
597 * Upgraded the protocol version to 1.1, updated protocol specs
600 * Added the nickname as new argument to NICK_CHANGE notify and
601 added it to protocol specs and implemented it to client and
602 server. Protocol TODO #3. Affected files are silcd/idlist.[ch],
603 silcd/command.c, silcd/packet_receive.c, packet_send.[ch], and
604 lib/silcclient/client_notify.c.

607 it to protocol specs and implemented it to client and server.
608 Protocol TODO #13. Affected files are silcd/command.c,
609 silcd/packet_receive.c, packet_send.[ch],
610 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
611 The killer's client entry is now returned to application in
612 the `notify' client operation.
614 * Fixed the Max Argument fields that had too large value set
615 in the protocol specs. Protocol TODO #14.
617 * Added the LEAVE command reply to return the ID of parted
618 channel. Updated protocol specs and implemented it to the
619 client and server. Protocol TODO #15. Affected files are
620 silcd/command.c, lib/silcclient/command_reply.c. The channel
621 entry is now returned to application in the `command_reply'
624 * Rewrote the version SKE version checking in client libary
625 and in server to use the silc_parse_version_string. Affected
626 files are lib/silcclient/protocol.c, silcd/protocol.c.
628 * Added SILC_STATUS_ERR_NO_CHANNEL_FOPRIV error status to few
629 commands that was missing it, and updated protocol specs and
630 the server implementation. Protocol TODO #10. The affected
631 file is silcd/command.c.
633 * Defined new message flags SILC_MESSAGE_FLAG_REPLY to be
634 generic reply to a generic request (REQUEST flag), and
635 SILC_MESSAGE_FLAG_DATA to send any kind of data in a generic
636 way. A draft-riikonen-silc-flags-payloads-00.txt is written
637 to define the payload for DATA flag. Added the flags to
638 the implementation. Protocol TODO #9. Affected file is
639 lib/silccore/silcchannel.h.
641 Changed the client library to return the message length
642 to application as well in the channel_message and private_message
643 client operations. Affected files are
644 lib/silcclient/client_prvmsg, lib/silcclient/client_channel.c,
645 lib/silcclient/silcclient.h, irssi/src/silc/core/client_ops.c,
646 and lib/silcclient/client_ops_example.c.
648 * Added two new channel modes: SILC_CMODE_SILENCE_USERS
649 and SILC_CMODE_SILENCE_OPERS which can be used to moderate
650 the channel. Updated protocol specs and impelemented this
651 to client and server. Protocol TODO #6. Affected files are
652 silcd/packet_receive.c, server_util.c, lib/silcclient/command.c,
653 lib/silcclient/client_channel.c, lib/silccore/silcmode.h.
655 Added new options m and M to CMODE command in Irssi SILC
656 client to set these modes.
658 * Deprecated all administrative commands from SILC protocol
659 since they are highly implementation specific commands.
660 Updated protocol specs. Moved the old commands in
661 implementations to private range of command types. Affected
662 files are silcd/command.c, lib/silcclient/command.c and
663 lib/silcclient/command_reply.c. Protocol TODO #8.
665 * Fixed a bug in server where sending unknown command crashes
666 the server. Affected file silcd/command.c.
668 Wed Apr 3 09:57:47 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
670 * Added SILC_PROTOCOLVERSION macro to check protocol version
671 of a socket connection. The affected file is
672 lib/silcutil/silcsockconn.h.
674 * Added better error logging in rekey protocol. Affected file
677 * Do not check public key types in SKE during rekey. Affected
678 file lib/silcske/payload.c.
680 * Fixed the rekey protocol with PFS, which was totally broken.
681 Affected file silcd/protocol.c.
683 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
685 * Some client implementations quit network by doing first LEAVE
686 and then immediately SIGNOFF (like Bombyx). We now do check
687 after a short time after LEAVE notify and check whether the
688 client is still valid after LEAVE, and if not we remove it from
689 cache. Affected file is lib/silcclient/client_notify.c.
691 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
693 * Merged version 1.1.4 of zlib. Even if it not currently in use,
694 it's good not to have security holes here.
696 * Fixed a negative refcount situtuation for the config context.
697 Affected file is silcd/serverconfig.c.
699 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
701 * ROBOdoc documented lib/silcutil/silcutil.h.
703 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
705 * Optimized even more the SilcPacketContext structure. Now
706 totally saved 16 bytes of memory per context after optimization.
707 Affected files are lib/silccore/silcpacket.[ch].
709 * Made strict checks for valid SILC IDs. Affected file is
710 lib/silccore/silcid.c.
712 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
714 * Changed the object argument for silc_cipher_register,
715 silc_hash_register, silc_hmac_register and silc_pkcs_register
716 to const. Affected files are lib/silccrypt/silccipher.[ch],
717 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
719 * Changed the silc_get_username and silc_get_real_name to
720 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
722 * Fixed the Irssi SILC Client to use the silc_get_username and
723 silc_get_real_name insted of glib routines since the glib
724 routines only corrupt stack. Fixes the Irssi SILC to work in
725 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
727 * Fixed the Irssi to not use g_get_home_dir since it crashes
728 or returns garbage on cygwin and corrupts stack. Added function
729 get_home_dir to Irssi routines. Affected files are
730 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
732 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
734 * Made some structure optimizations. SFTP memory FS MemFSEntry
735 entry structure. Optimized SilcTask structure. Optimized
736 SilcPacketContext structure.
738 Affected files lib/silcsftp/sftp_fs_memory.c,
739 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
741 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
743 * And yet again reverted back the config thing since Johnny
744 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
747 * Fixed memory leaks from config object. Affected files are
748 silcd/serverconfig.[ch].
750 * Added support for adding new connections to the server in rehash.
751 After rehash they take effect.
753 Added support for changing the maximum allowed connections in
754 rehash. The number can grow but going smaller is not supported.
756 Added function silc_server_num_sockets_by_remote to the
757 silcd/server_util.[ch].
759 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
761 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
763 * Added preliminary checking during config parsing for a valid
764 public/private key and removed further checks in the code.
765 Affected files are silcd/serverconfig.[ch], server.c.
767 * Moved functions silc_server_drop() and silc_server_daemonise()
768 from server.c to silcd.c since they are stricly related to
769 the application activity.
771 * Reverted a small part of the automatic ref/unref since
772 it caused a double unref in some situations. Affected
773 files are silcd/silcd.[ch], server.c, serverconfig.c.
775 * Added some .cvsignore files in the lib directory.
777 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
779 * Fixed silc_net_gethostbyaddr to correctly resolve by
780 address. Affected file lib/silcutil/silcnet.c.
782 * Fixed the notify relaying to client. The HMAC to be used
783 with relayed packets ws wrong and caused decryption failure
784 at the client end. Affected file is silcd/packet_receive.c.
786 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
788 * Created new branch silc_protocol_1_0_branch.
790 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
792 * Changed the silc_server_config_* routines to be SilcServer
793 independent. They are now officially application specific code
794 and not part of generic server implementation. Affected files
795 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
797 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
799 * Added automatic referencing of config context in the
800 silc_server_config_alloc, and automatic unreferencing in the
801 silc_server_config_destroy. Affected files are
802 silcd/serverconfig.[ch], silcd/silcd.c.
804 * Fixed the silc_log_quick handling in the logging routines.
805 It didn't log quickly when it was TRUE. Affected file is
806 lib/silcutil/silclog.c. Also the flush delay was set even
807 if it was 0 in config file. Affected file is
808 silcd/serverconfig.c.
810 * Added support for changing key pair of the server in rehash.
811 Affected file silcd/server.c.
813 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
815 * Fixed the TOPIC_SET notify to not cras. It changed the topic
816 too early, before getting the channel entry. Affected file
817 is silcd/packet_receive.c.
819 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
821 * Added functions silc_server_config_[ref/unref], these are used
822 to prevent that the config object is destroyed.
824 No longer directly affect global variables silc_log_quick and
825 silc_log_delay, they are first cached inside the config object
826 and then applied with silc_server_config_setlogfiles().
828 silc_server_config_set_defaults() is now internal to
829 serverconfig.c, there are no reasons to show this internal stuff
832 Affected files are silcd/serverconfig.[ch].
834 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
835 fprintf's to stderr, since some code may be executed again after
836 the server went into the background. Affected files are
839 * Added rehash support. Added function silc_server_rehash() that
840 will perform all the basic tasks of the rehashing procedure.
842 * Added command line option `-x, --hexdump'. This will enable the
843 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
844 The option `--hexdump' implies `--debug'.
846 * Fixed a bad bug in the logging APIs (silcutil library) where
847 the application would crash after calling silc_log_reset_all().
849 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
851 * Fixed the KICKED notify handling in client library to
852 correctly remove the channel and all entries from the
853 channel when I was kicked. This bug crashed the client.
855 Fixed yet another but in KICKED notify handling to remove
856 the kicked client correctly from the channel.
858 Affected file is lib/silcclient/client_notify.c.
860 * Fixed a minor bug in looking up correct client entry
861 in KICKED notify in server. Affected file is
862 silcd/packet_receive.c.
864 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
865 sources correctly to distribution. Fixes --with-gmp option.
867 * Removed the manual rehashing from ID Cache, and changed it
868 to use the SILC Hash Table's auto rehash feature. Affected
869 file is lib/silccore/silcidcache.c.
871 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
873 * Fixed a bug in the silc_client_nickname_format function that
874 handles the multiple same nickname formatting. Two clients
875 with same nickname caused problems after the first one left
876 and rejoined. It didn't format the nickname correctly.
877 Affected file is lib/silcclient/idlist.c.
879 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
881 * Don't change the topic if olod topic is same as new one.
882 Affected file is silcd/packet_receive.c.
884 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
886 * Added cross-reference support to the SILC Documentation
887 generator. All types across all HTML files are now cross-
888 referenced. Affected files util/robodoc/generator.c and
889 scripts/silcdoc/silcdoc.
891 * Added file lib/silcutil/silctypes.h to include all the
892 arithmetic type definitions and some macros. Removed
893 includes/bitmove.h and moved macros to silctypes.h.
895 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
897 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
899 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
901 * Added `type' argument to silc_id_payload_parse_id function which
902 now returns the type of the ID to the sent pointer. Affected
903 file is lib/silccore/silcid.[ch].
905 * Added check for CMODE_CHANGE notify type that mode change is
906 allowed by the sender. Affected file silcd/packet_receive.c.
908 * Added check for CUMODE_CHANGE notify type that mode change is
909 allowed by the sender. Affected file silcd/packet_receive.c.
910 Added the ID type as CUMODE_CHANGE notify type as argument
911 to the `notify' client operation. Affected files are
912 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
914 * Added function silc_client_add_server to the client library.
915 Added support for resolving also channel and server info when
916 received unknown entity in notify packet. Affected files are
917 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
919 * Added function silc_command_get_status to return the command
920 status from the command reply's argument payload. Affected files
921 are lib/silccore/silccommand.[ch].
923 * Added check for KICKED notify type that the kicking is
924 allowed by the client. Affected file silcd/packet_receive.c.
926 * Created function silc_get_input which can be used to get input
927 (echo on or off) from user on command line. Affected files are
928 lib/silcutil/silcutil.[ch].
930 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
932 * Optimized silc_server_packet_relay_to_channel function.
933 Added new function silc_channel_message_payload_encrypt which
934 can be called directly if channel message payload needs to
935 be encrypted and is already encoded (no need to call _encode
936 function). Packet relaying is now done by router without any
937 extra memory allocations. Affected files are
938 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
941 * Fixed the INVITE notify handling. It took wrong arguments
942 as invite list and invite delete. Affected file is
943 silcd/packet_receive.c.
945 * Added check for TOPIC_SET notify type that the topic change is
946 allowed by the client. Affected file silcd/packet_receive.c.
948 * Added check for INVITE notify type that inviting is allowed by
949 the client. Affected file silcd/packet_receive.c.

952 SilcChannelClientEntry as well. Moved the function
953 silc_server_check_cmode_rights to server_util.[ch].
954 Affected files are silcd/server_util.[ch], silcd/command.c.
956 * Added function silc_server_check_umode_rights to check whether
957 changing client's user mode is allowed. Added check for
958 UMODE_CHANGE notify type that the umode change is allowed
959 by the client. Affected files are silcd/server_util.[ch],
960 silcd/packet_receive.c and silcd/command.c.
962 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
964 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
965 ID length. It ignored that ID can be IPv6 based as well.
966 Affected file lib/silccore/silcpacket.h.
968 * Fixed the silc_id_id2str and silc_id_str2id to take the
969 IPv6 address offset's into consideration. Affecte file is
970 lib/silccore/silcid.c.
972 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
974 * Fixed the internal Unix scheduler functions to check for
975 NULL context they may receive. The affected file is
976 lib/silcutil/unix/silcunixschedule.c.
978 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
980 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
981 can specify different directory with --home command line
982 parameter. Affected files irssi/src/silc/core/client_ops.c,
985 * SILC-specific commands aren't now executed if the active server
986 isn't of SILC-type, so there won't be problems with having
987 IRC and SILC protocol support in same client. Affected files
988 irssi/src/silc/core/silc-channels.c, silc-servers.c,
991 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
993 * Improved the signal support in SILC Schedule. Added new
994 function silc_schedule_signal_call which is used by application
995 to mark a signal to be called. It is now safe to perform
996 any kind of tasks in signal callbacks since it is guaranteed
997 that the application specified signal callback is called
998 after the signal is over. Affected files are
999 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
1001 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1003 * Added `name' field to SilcChannelPrivateKey to represent
1004 application given name for the key. Moved also the context from
1005 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
1006 Added the `name' argument also to the function
1007 silc_client_add_channel_private_key.
1009 Added function silc_client_current_channel_private_key to set the
1010 current channel private key in use.
1012 Added "change" command to KEY command which can be used to change
1013 the current channel private key. Bound the command also to
1014 alt+K (Alt+Shift+k).
1016 Also affected files lib/silcclient/client_channel.c,
1017 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
1019 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1021 * Added silc_rng_get_byte_fast function in to the
1022 lib/silccrypt/silcrng.[ch].
1024 * Changed the interface of silc_packet_assemble and the
1025 silc_packet_send_prepare. If silc_packet_assmble is now
1026 called the application does not call silc_packet_send_prepare
1027 because the library will call it automatically. These
1028 interfaces now also return a reference to the outgoing buffer
1029 which includes the assembled packet, which the application can
1030 use to encrypt the packet.
1032 Affected files are lib/silccore/silcpacket.[ch],
1033 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
1034 silcd/packet_send.c, server_backup.c and packet_receive.c.
1036 * Fixed a packet sending bug on very high load, where outgoing
1037 packet queue wasn't handled correctly and packets got corrupted.
1038 Affected files are lib/silcutil/*/silc*sockconn.c,
1039 lib/silcclient/client.c and silcd/server.c.
1041 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1043 * Added macro SILC_PACKET_DATALEN which can be used during
1044 packet assembling to check whether the data to be added to
1045 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
1046 len is truncated until it fits it.
1048 Added checks for maximum length of channel message payload and
1049 private message payload also.
1051 Added checks for maximum packet length in server and in
1054 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
1055 lib/silcclient/client.c, lib/silccore/silcchannel.c and
1056 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
1057 lib/silcclient/client_prvmsg.c.
1059 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1061 * Added silc_server_packet_queue_purge call to the
1062 silc_server_disconnect_remote to assure that all data in the
1063 queue before disconnecting is sent to the network. Affected
1064 file silcd/server.c.
1066 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1068 * Added the deleting of server's own ID cache entry to the
1069 silc_server_free function. Free also everything else that
1070 has been allocated in silc_server_init. The affected file
1073 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1075 * Added functions silc_parse_version_string, silc_version_to_num,
1076 and silc_ske_parse_version to parse SILC protocol style version
1077 strings. Affected files lib/silcutil/silcutil.[ch] and
1078 lib/silcske/silcske.[ch].
1080 * Added new configuration params: version_protocol, version_software
1081 and version_software_vendor to specify what version the remote
1082 host must at least be to be able to connect to server. The vendor
1083 string can be regex matched too. Added new function
1084 silc_server_connection_allowed to check maximum number of allowed
1085 connections, and allowed versions for incoming connections.
1086 Affected files are silcd/server.c, server_util.[ch] and
1089 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1091 * Added preliminary support for signals in scheduler. The
1092 signals we care about are now blocked always when the scheduler
1093 is locked. This way we can synchronise the use of signal with
1094 scheduler. It is guaranteed that when signal occurs the scheduler
1095 is not locked, and thus new tasks can be safely added to the
1098 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
1099 to silc_schedule_internal_init and silc_schedule_internal_uninit.
1100 Added new platform specific routines
1101 silc_schedule_internal_signals_[un]block and
1102 silc_schedule_internal_signal_[un]register.
1104 Added new functions to SILC Schedule API:
1105 silc_schedule_signal_[un]register. Each signal that application
1106 is going to use should be registered to the scheduler.
1108 Affected files are lib/silcutil/silcschedule.[ch],
1109 lib/silcutil/*/silc*schedule.c.
1111 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1113 * Check for unauthenticated client and server in the
1114 silc_server_new_client and silc_server_new_server functions.
1115 Affected file silcd/packet_receive.c.
1117 * Added function silc_string_is_ascii to check whether given
1118 string is 7-bit ASCII string. Affected files are
1119 lib/silcutil/silcutil.[ch].
1121 * Added function silc_id_is_valid_server_id into the
1122 silcd/serverid.c and added checking for valid Server ID's in
1123 silc_server_new_server. The Server ID must always be based
1124 on the server's public IP address.
1126 * Added logging of DISCONNECT packet message in the server.
1127 Affected file silcd/server.c.
1129 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1131 * Changed all library interfaces that use Global RNG to also
1132 accept SilcRng as argument. Affected files are
1133 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
1134 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
1135 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
1136 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
1137 lib/silccrypt/rsa.c.
1139 * Added function silc_pkcs_generate_key to the
1140 lib/silccrypt/silcpkcs.[ch] for applications so that they
1141 don't need to do pkcs->pkcs->init calls anymore.
1143 * Remove SilcSocketConnection from the SFTP API since it really
1144 wasn't needed there. The application has the information
1145 saved in its contexts anyway and the SFTP layer doesn't need
1146 know about it. Affected files lib/silcsft/silcsftp.h and
1147 lib/silcsftp/sftp_[server/client].c.
1149 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
1150 The SilcSimContext is not SilcSim.
1152 * Fixed possible buffer overflows in silc_id_render in the
1153 lib/silcutil/silcutil.c.
1155 * On EPOC the global crypto module lists are not used at all
1156 in the crypto library. Added support for using the constant
1157 algorithm list on EPOC. Affected files are
1158 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
1161 * Fixed the handling of third parameter of KICKED notify, since
1162 it was mistakenly updated to SILC Protocol 1.0 even though it
1163 is to be included in 1.1. Since it is not in 1.0 it is not
1164 mandatory, and this fix now handles it only if it is provided,
1165 and it is not error if it is not provided. Affected file
1166 lib/silcclient/client_notify.c.
1168 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1170 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
1171 client. Affected file irssi/src/silc/core/client_ops.c.
1173 * Merged with Irssi 0.8.4 from irssi.org CVS.
1175 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1177 * Check for valid socket connection in client entries before
1178 sending any messages. Fixes a crash, but doesn't fix some
1179 other underlaying bug that is lurking there. Affected
1180 file silcd/packet_send.c.
1182 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
1184 * $usermode, $cumode and $cumode_space expandos shouldn't do
1185 anything with non-SILC server records. Affected file
1186 irssi/src/silc/core/silc-expandos.c
1188 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1190 * Fixed the silc_net_check_[host/local]_by_sock to support
1191 IPv6 bound sockets as well. Now they can return IPv6 addresses
1192 as well. Affected file lib/silcutil/silcnet.c.
1194 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
1195 Affected lib/silcutil/unix/silcunixnet.c.
1197 * Fixed ID rendering (at least on some platforms, not NetBSD)
1198 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
1200 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1202 * Added silc_hash_public_key and silc_hash_public_key_compare
1203 functions to be used with SilcHashTable. They can be used to
1204 hash public keys and compare public keys in hash table. Affected
1205 file lib/silcutil/silcutil.[ch].
1207 * Added support for specifying multiple public keys for Client
1208 connection section in server configuration file. This makes it
1209 possible to accept multiple public keys from same host, or to
1210 make a section that accepts any incoming host, and have the
1211 accepted public keys listed in the section.
1213 Added functions silc_sever_[find/get]_public_key, added the
1214 support for this actually to all connection sections but only
1215 the Client section is currently allowed to specify multiple
1218 Affected files are silcd/server.c, server_internal.h,
1219 command.c, protocol.c, server_util.[ch], packet_receive.c.
1221 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1223 * Merged Irssi 0.8.2 from irssi.org CVS.
1225 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1227 * If silc_debug is TRUE, also output standard logging messages
1228 to stderr with the debug output.
1230 Made silc_log_reset_all() flushing all channels before returning.
1231 Also fixed some documentation typos.
1233 Affected files are lib/silcutil/silclog.[ch].
1235 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1237 * Fixed the server to check correctly the amount of connections
1238 from single host, by checking also the type of the connection.
1239 Fixed also the comparison of number of connections and number
1240 of allowed connections. Affected files are silcd/server.c,
1243 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1245 * Fixed the USERS command reply to save the user's mode on the
1246 channel as well. Fixed JOIN command reply to check whether a
1247 client is on channel already and not join it twice. Affected
1248 file lib/silcclient/command_reply.c.
1250 * Added new file silc-expandos.c into irssi/silc/core/ to return
1251 various stuff for various signal for the statusbar etc. updating.
1252 Now Irssi SILC client prints channel user modes etc. on the
1255 * The user mode (like server/router operator changes) is now shown
1256 on the Irssi SILC client's statusbar. The affected files are
1257 irssi/src/silc/core/client_ops.c, silc-expandos.c.
1259 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1261 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
1262 to SILC_SCHEDULE_[UN]LOCK macros.
1264 * Added more error printing to logs in server code. Affected
1265 files silcd/server.c and silcd/protocol.c.
1267 * Fixed -S option parsing in Irssi SILC Client. Affected file
1268 irssi/src/silc/core/silc-core.c.
1270 * Added silc_buffer_alloc_size function. Affected file is
1271 lib/silcutil/silcbuffer.h.
1273 Tue Mar 5 14:37:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1275 * Changed all silc_[hash|hmac|cipher|pkcs]_default tables to
1276 constants. Affected files in
1277 lib/silccrypt/silcpkcs.[ch], silchash.[ch], silchmac.[ch] and
1280 * Changed the internal SFTP Memory FS table to const. Affected
1281 file lib/silcsftp/sftp_fs_memory.c.

1293 Sun Feb 24 12:53:25 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1295 * Changed all integer type names:
1296 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
1297 to avoid collisions with other libraries using same type names
1300 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1302 * Added `prefer_ipv6' argument to the functions
1303 silc_net_gethostbyname[_async]. If it is TRUE it will return
1304 IPv6 address over IPv4. If FALSE IPv4 address is returned
1305 even if IPv6 address was found. Affected files
1306 lib/silcutil/silcnet.[ch].
1308 * Added support silc_net_create_connection[_async] to fallback
1309 to IPv4 address if IPv6 address could not be used (like if
1310 it doesn't work on a specific system). Affected file in
1311 lib/silcutil/unix/silcunixnet.c.
1313 Sat Feb 23 15:20:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1315 * Added silc_schedule_reinit function to do the enlarging
1316 of the max tasks handling capabilities of the scheduler.
1317 Affected files lib/silcutil/silcschedule.[ch].
1319 Wed Feb 20 20:41:01 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1321 * Added automatic extern "C" { ... } for C++ compilers so the
1322 application does not need to define them. Affected file
1323 includes/silcincludes.h.
1325 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
1326 old name went against naming convention. Applications now
1327 include "silcclient.h" instead of "clientlibincludes.h".
1328 Removed includes/clientlibincludes.h, it is redundant now.
1330 * Renamed includes/version.h to silcversion.h.
1332 * Added really preliminary support for OS/2 into the util
1333 library. Only thread & mutex API is implemented, others
1334 are still to be implemented. Created the lib/silcutil/os2/
1335 directory. Created also file includes/silcos2.h.
1337 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1340 Created lib/silcutil/beos/, and implemented all the needed
1341 functions to support SILC on BeOS. Created also file
1342 includes/silcbeos.h.
1344 Mon Feb 18 15:49:22 EET 2002 Timo Sirainen <tss@iki.fi>
1346 * Added proper initializations to silc's irssi code, so it's
1347 now possible to load it as module. Affected files
1348 irssi/src/silc/core/silc-core.c,
1349 fe-common/silc/fe-common-silc-core.[ch] and fe-text/silc.c
1351 Sun Feb 17 19:02:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1353 * Merged latest Irssi (0.8.1) from the irssi.org's CVS into
1356 * Fixed the silcdoc document generator to correct generate
1357 docs from all kinds of filenames. Affected files are

1368 * Added `user_count' to the SilcChannelEntry which now tells the
1369 number of users on the channel. The user count is now saved
1370 in normal server of global channels as well. Affected files
1371 silcd/server.c, idlist.h, packet_receive.c and command.c.
1373 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
1374 include file utility functions.
1376 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
1377 instead of calling directly OS routines.
1379 * Fixed NICK change printing in Irssi SILC Client. Fixed
1380 KICKED notify printing in Irssi SILC Client. Affected file
1381 irssi/src/silc/core/client_ops.c.
1383 * Fixed a NICK change bug in client library, to not recreate the
1384 client_entry->channels hash table everytime nick is changed.
1385 Affected file lib/silcclient/client.c.
1387 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1389 * ROBOdoc documented the lib/silcske/silcske.h, and improved
1390 the SKE interface a bit.
1392 * Fixed padding problem in PKCS#1. The padding was not actually
1393 random since the random number generator was used incorrectly.
1394 This security bug affects only when encrypting with PKCS#1, and
1395 it is not currently used at all in SILC. SILC only use signing
1396 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
1398 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1402 Affected files irssi/src/silc/core/client_ops.c, silc-channels.c.
1404 * Send the auto-nicking NICK command in client library with
1405 little timeout after connecting. The affected file is
1406 lib/silcclient/client.c.
1408 * Added following new config file settings:
1409 channel_rekey_secs, key_exchange_rekey, key_exchange_pfs,
1410 key_exchange_timeout, conn_auth_timeout, connections_max,
1413 Implemented all the new config settings handling in the server.
1415 Optimized the use of SKE Mutual flag usage. Use it only
1416 if connection authentication protocol is not based in public
1419 Renamed all SilcServerConfigSection* to SilcServerConfig*
1420 to have a bit shorter names.
1422 Affected files silcd/serverconfig.[ch], server.[ch], and
1425 Sat Feb 16 02:46:43 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

1451 Affected files are silcd/serverconfig.[ch].
1453 Fri Feb 15 12:24:08 EET 2002 Timo Sirainen <tss@iki.fi>
1455 * Fixed command line parameter handling. All SILC initialization
1456 is now done in silc_core_init() which also fixes autoconnecting
1459 Affected files irssi/src/silc/core/silc-core.c,
1460 irssi/src/fe-text/silc.c.
1462 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1464 * Added new configuration options and blocks:
1465 keepalive_secs, reconnect_count, reconnect_interval,
1466 reconnect_interval_max, reconnect_keep_trying and
1467 require_reverser_lookup. Added ConnectionParam block, and
1468 implemented the connection parameters when connecting as
1469 initiator and when accepting connections as responder.
1471 Added CONFIG_IS_DOUBLE macro in config file parsing, to check
1472 whether given configuration value has been given already.
1474 Affected files silcd/serverconfig.[c], server.[c].
1476 * Splitted the doc/example_silcd.conf.in. Separated the crypto
1477 algorithm parts and created new file silcalgs.conf, that
1478 is now included from the example_silcd.conf.in.
1480 * Optimized the silc_server_connect_to_router_second to take
1481 the connection configuration object from the SilcServerConnection
1482 object instead of finding it during the connecting phase.
1483 Added the configuration object to SilcServerConnection struct.
1484 Affected files silcd/server_internal.h, server.c.
1486 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1488 * Add the client on channel after it was resolved at the
1489 channel message receiving, and it was not already on the
1490 channel. Affected file lib/silcclient/client_channel.c.
1492 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1494 * Fixed the public key authentication to allocate always the
1495 destination signature buffer instead of using static buffer.
1496 Affected file silcd/protocol.c.
1498 Wed Feb 13 20:51:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1500 * Unified the serverconfig.[ch]'s helper function interface.
1501 Affected file silcd/serverconfig.[ch].
1503 * Removed doc/example_silc.conf.in since it is redundant.
1504 The make install will now install irssi/silc.conf file.
1506 * Added new Passphrase and Publickey authentication methods to
1507 config file, allowing both public key and passphrase based
1508 authentication to be set at the same time.
1510 Added `prefer_passphrase_auth' setting in config file which
1511 can be used to set to prefer passwd auth if both passwd and
1512 public key is set. If not set, public key is preferred.
1513 This has effect only when being initiator (responder will try
1516 Added support for authentication with passphrase and public key
1517 at the same time. The passphrase is tried first always since
1518 it is faster to check.
1520 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
1522 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1524 * Merged the new SILC Config library, with the server parsing
1525 support. Read the header file silcconfig.h or the toolkit
1526 documentation for the news. Affected files are

1533 lib/silcutil/silclog.h.
1535 Sun Feb 10 18:11:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1537 * The silc_cipher_register, silc_hash_register and
1538 silc_hmac_register now checks if the object to be registered
1539 is registered already. Affected files are
1540 lib/silccrypt/silccipher.c, silchash.c and silchmac.c.
1542 Sun Feb 10 15:48:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1548 * Allow zero length channel messages inside the Channel Message
1549 Payload. Affected file lib/silccore/silcchannel.c.
1551 * Fixed scripts/silcdoc/silcdoc to support all kinds of filenames
1552 as header filenames.
1554 * Removed lib/silcclient/README and created HTML file
1555 lib/silcclient/silcclient_using.html, which is now included
1556 as part of Toolkit documentation.
1558 Thu Feb 7 10:12:25 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1560 * Fixed CUMODE_CHANGE notify handling to change the mode of
1561 correct client. Affected file lib/silcclient/client_notify.c.
1563 * Make silc_rng_alloc fail if it cannot allocate the sha1
1564 hash algorithm. Affected file lib/silccrypt/silcrng.c.
1566 Sun Feb 3 17:20:52 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1568 * Fixed the file transfer's key agreement payload to include
1569 zero port also if the hostname is NULL because it could not
1572 Call file transfer monitor callback now also if error occurs
1573 during key agreement protocol.
1575 Changed the silc_client_file_send interface to return the
1576 SilcClientFileError instead of session id. The session ID
1577 is returned into pointer provided as argument.
1579 Check that the file exists locally before sending the
1580 file transfer request at all.
1582 Affected file lib/silcclient/client_ftp.c, silcapi.h.
1584 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer
1585 error than can occur while key agreement protocol. Affected
1586 file lib/silcclient/silcapi.h.
1588 * Fixed the event_mode CMODE handler to not crash when mode
1589 is changed and +k mode is set in the channel. Affected file
1590 irssi/src/silc/core/silc-channels.c.
1592 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
1593 SILC_LOG_WARNING to give out Warning and not Error. Affected
1594 file lib/silcutil/silclog.c.
1596 * Fixed the channel message payload decryption in the function
1597 silc_channel_message_payload_decrypt to not modify the original
1598 buffer before it is verified that the message decrypted
1599 correctly. Otherwise, next time it is called with correct
1600 channel key it won't encrypt since the payload is corrupted.
1601 Affected file lib/silccore/silcchannel.c.
1603 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1605 * Do not constantly resize the window. A fix patch by cras.
1606 Affected file irssi/src/fe-text/screen.c.
1608 Sat Feb 2 16:54:18 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1610 * Applied IPv6 fix patch from Jun-ichiro itojun Hagino.
1611 Affected file lib/silcutil/silcnet.c.
1613 Fri Feb 1 22:33:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1615 * Fixed a bug in hash table internal routine for traversing
1616 the table with foreach callback. The current entry may
1617 become invalid in the callback but it was referenced after
1618 the callback returned.
1620 Do not allow auto rehashing of hash table during the
1621 silc_hash_table_foreach operation, for same reasons as it is
1622 not allowed for SilcHashTableList. Affected files are
1623 lib/silcutil/silchashtable.[ch].
1625 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1627 * Defined DLLAPI into silcincludes.h and silcwin32.h for
1628 Win32 DLL. extern's in header files are now declared with
1631 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1633 * Fixed private message handling. It used some old code that
1634 caused the client to crash. Affecte file is
1635 lib/silcclient/client_prvmsg.c.
1637 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1639 * Added function silc_client_add_channel,
1640 silc_client_replace_channel_id, and removed functions
1641 silc_client_new_channel_id and silc_idlist_get_channel_by_id
1642 from client library.
1644 * Added cross reference of the joined channels to the
1645 SilcClientEntry, and changed the SilcChannelEntry's
1646 users list to SilcHashTable. The affected files are
1647 lib/silcclient/idlist.[ch].
1649 * Fixed a bug in hash table tarversing. While the hash table
1650 is traversed with SilcHashTableList the table must not be
1651 rehashed. It is now guaranteed that auto rehashable tables
1652 are not rehashed while tarversing the list. Also defined that
1653 silc_hash_table_rehash must not be called while tarversing
1654 the table. Added function silc_hash_table_list_reset that must
1655 be called after the tarversing is over. The affected files are
1656 lib/silcutil/silchashtable.[ch].
1658 * Changed all hash table traversing to call the new
1659 silc_hash_table_list_reset in server and in client library.
1661 * Added function silc_client_on_channel to return the
1662 SilcChannelUser entry if the specified client entry is joined
1663 on the specified channel. This is exported to application as
1664 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
1666 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1668 * Fixed founder regaining problem with JOIN command on normal
1669 server. The notify for mode change must be sent always and
1670 not only if !cmd->pending. Affected file silcd/command.c.
1672 * Fixed the WHOWAS command's reply sending to support the
1673 lists correctly. Affected file silcd/command.c.
1675 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1677 * When sending JOIN command to router for processing the
1678 sender's old command identifier was not saved back to the
1679 sender's command context, fixed now. The affected file is
1682 * Create the key in JOIN command of the router did not return
1683 the channel key, added check for this. Affected file is
1686 * Fixed a channel ID update bug in JOIN command reply. Do
1687 not directly upgrade the ID but call the function
1688 silc_idlist_replace_channel_id if the ID was changed.
1689 Affected file silcd/command_reply.c.
1691 * Fixed memory leaks from command calling if it would fail.
1692 Affected file silcd/command.c.
1694 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1696 * Applied patches from cras:
1698 Memory leak fixes around libaries, irssi window resize fix,
1699 new silclist.h and silcdlist.h, all extern inline changed to
1702 * Removed dotconf from lib/dotconf, not needed anymore.
1704 * Removed TRQ from lib/trq, not needed anymore.
1706 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
1707 with server connections. Later this will be configurable
1708 in config file after new config file is done. Affected file
1711 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1713 * Fixed a crash in server related to channel announcements.
1714 Affected file silcd/server.c.
1716 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1718 * Fixed memory leaks in silc_server_create_new_channel*
1719 functions. Affected file silcd/server.c.
1721 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
1722 which ID was changed. This way the router will send the
1723 user list for the channel again, and server won't be in
1724 desync in some rare circumstances. Affected file is
1725 silcd/packet_receive.c.
1727 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1729 * Check for NULL socket pointer in the function
1730 silc_server_packet_send_to_channel_real. Affected file
1731 silcd/packet_send.c.
1733 * Fixed the BAN notify handling to correctly remove ban
1734 list. Affected file silcd/packet_receive.c.
1736 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1738 * Fixed some header addition to Toolkit distribution in
1739 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
1741 * Added lib/silcclient/client_ops_example.h as an template
1742 file for application programmers to quickly start using
1743 the SilcClientOperation functions in their application.
1744 Updated the lib/silcclient/README as well to tell about this
1745 nice file made available.
1747 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1749 * Call silc_server_remove_from_channels when removing client
1750 entry when NO_SUCH_CLIENT_ID was received. Affected file
1751 is silcd/command_reply.c.
1753 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1755 * Added server & router operator statistics updating. Affected
1756 file silcd/packet_receive.c and silcd/command.c.
1758 * Fixed the SERVER_SIGNOFF notify handling on normal server
1759 not to save the history information for clients. Same was
1760 fixed earlier in remove_clients_by_server function, but not
1761 here. Affected file silcd/packet_receive.c.
1763 * Raised the default connection-retry count from 4 to 7 in
1764 server. Affected file silcd/server.h.
1766 * Cancel any possible reconnect timeouts when we start the
1767 key exchange. Affected file silcd/server.c.
1769 * Do not reconnect on connection failure when SCONNECT was
1770 given. Affected files silcd/server.[ch].
1772 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1774 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
1776 * Fixed the NICK command to always give the unformatted
1777 nickname to the one giving the NICK command. If unformatted
1778 nickname is cached already it will be formatted and the
1779 local entry will always get the unformatted nickname.
1780 Affected file lib/silcclient/idlist.c.
1782 * Fixed some double frees from client library commands.
1783 Affected file is lib/silcclient/command.c.
1785 * Fixed CUMODE command in server to assure that no one can
1786 change founder's mode than the founder itself, there was a
1787 little bug. Affected file silcd/command.c.
1789 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1791 * Removed the SilcClientCommandDestructor from the client
1792 libary, it is not needed anymore. Affected files are
1793 lib/silcclient/silcapi.h, command[_reply].[ch],
1794 client_notify, idlist.c.
1796 * Fixed GETKEY command to first resolve client, and then
1797 resolve the server only if the client was not found, instead
1798 of resolving both at the same time. Affected file is
1799 lib/silcclient/command.c.
1801 * Added silc_client_start_key_exchange_cb and lookup the
1802 remote hostname and IP address before starting the key
1803 exchange with server. The affected file is
1804 lib/silcclient/client.c.
1806 * The server's public key is now saved using the IP address
1807 of the server and not the servername for the filename.
1808 The hostname public key filename is checked as an fall back
1809 method if the IP address based filename is not found.
1811 Fixed the GETKEY command to save the fetched server key
1812 in correct filename.
1814 Print the remote server's hostname now when new key is
1815 received during connection process. Affected file is
1816 irssi/src/silc/core/client_ops.c.
1818 * Return always our own public key to the client if it asks
1819 for it with GETKEY command. Affected file silcd/command.c.
1821 * Removed the use_auto_addr variable from default config
1822 file since it was in wrong section. Affected file is
1825 * Fixed TOPIC_CHANGE notification to not route it when it
1826 was sent using silc_server_send_notify_to_channel function.
1827 Affected file silcd/command.c.
1829 * Fixed silc_server_send_notify_kicked to send the kicker's
1830 Client ID also, it was missing. Affected files are
1831 silcd/command.c, silcd/packet_send.[ch].
1833 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1835 * Do not save client history information in SERVER_SIGNOFF.
1836 Fixes the bug in normal server that it does not detect
1837 the client becoming valid after the server becomes back
1838 online. Affected file silcd/server_util.c.
1840 * Added `sock_error' field into the SilcSocketConnection
1841 context. When error occurs during socket operation (read
1842 or write) the error is saved. Added also new function
1843 silc_socket_get_error to return human readable socket error
1844 message. Affected files are lib/silcutil/silcsockconn.[ch],
1845 lib/silcutil/unix/silcunixsockconn.c, and
1846 lib/silcutil/win32/silcwin32sockconn.c.
1848 * The server now prints the socket error message in the
1849 signoff for client. Affected file silcd/server.c.
1851 * Fixed the `created' channel information sending from router
1852 to server in JOIN command. Checks now whether the channel
1853 really was created or not and set it according that.
1855 Fixed the JOIN command to use the client entry's current
1856 ID during the joining procedure instead of the one it sent
1857 in the command (it is checked though), since it can change
1858 between the packet processing and command processing, and
1859 would just case unnecessary pain in the client end. Affected
1860 file silcd/command.c.
1862 * Fixed a channel key payload sending to use correct channel
1863 ID when the server was forced to change the channel's ID by
1864 router. Router sent the key payload with the old Channel ID.
1865 Affected file silcd/packet_receive.c.
1867 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1869 * Call silc_server_save_channel_key only if the key payload
1870 was provided in the JOIN command's command reply. Affected
1871 file silcd/command_reply.c.
1873 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1875 * Fixed silc_mp_sizeinbase to return the value correctly with
1876 MPI. Affected file lib/silcmath/mp_mpi.c.
1878 * Fixed the stop_server signal to correctly stop the scheduler
1879 and gracefully stop the server when SIGTERM or SIGINT signals
1880 are received. Affected file silcd/silcd.c.
1882 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1884 * Simple handling of TERM and HUP signals. Also added some log
1885 flushing call around. Affected file is
1888 * Fixed small bugs in silclog.c. Now buffering output will take
1889 effect after 10 seconds since startup: This will ensure that
1890 no important startup messages are lost. Also output redirection
1891 will preserve original format ([Date] [Type] message).
1892 Affected file is lib/silcutil/silclog.c.
1894 * Added two options to the config file, in the logging section:
1895 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1896 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1898 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1900 * Do not print the warning about log files not being initialized
1901 more than once to avoid excess logging. Affected file is
1902 lib/silcutil/silclog.c.
1904 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1905 the SIM copying in make install in Makefile.am.pre.
1907 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1909 * Rewritten silclog APIs. Globally interesting changes follows:
1910 silc_log_set_files() changed to silc_log_set_file().
1911 silc_log_set_callbacks() changed to silc_log_set_callback().
1912 ROBOdoc documented silclog header file.
1913 SilcLogCb now returns bool to wether inihibit the default
1914 handler or not (to keep the old behaviour return always TRUE).
1915 The new APIs should also fix the problem of the
1916 silcd_error.log file that was written in the current directory.
1919 Log files streams will remain opened after silc_log_set_file()
1920 call, means less CPU usage notably on high traffic servers.
1921 File streams are now full buffered, and flushed to the disk
1922 every 5 minutes, lesses HD activity and CPU usage.
1923 Messages can be redirected, allowing admins to configure
1924 one single logfile for all server messages.
1925 the silc_log_quick global variable to activate fast-logging.
1926 Affected files lib/silcutil/silclog.[ch]
1928 * Changed some code to conform new silclog APIs. Affected
1929 files are doc/example_silcd.conf.in, silcd/server.c
1930 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1933 * Fixed a memory leak that could occur in some situations.
1934 Affected file silcd/serverconfig.c.
1936 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1938 * Added the silc_client_del_client to remove the client from
1939 all channels as well. Affected file lib/silcclient/idlist.c.
1941 * Fixed the client library to correctly remove the client
1942 from all channels when the client entry is being destroyed.
1943 Affected file lib/silcclient/client_notify.c, command.c.
1945 * Added auto-nicking support to the client library. If the
1946 applicatio now sets client->nickname it will be sent to the
1947 server after connecting by the library. This way for example
1948 SILCNICK (or IRCNICK) environment variables will have effect
1949 and always change the nickname automatically to whatever
1950 it is wanted. Affected file lib/silcclient/client.[ch].
1952 * Renamed silc_server_command_bad_chars to the
1953 silc_server_name_bad_chars and moved it to the
1954 silcd/server_util.[ch]. Added also new function
1955 silc_server_name_modify_bad to return nickname that
1956 includes bad characters as new nickname without those
1957 bad characters. This check and modify is now used in
1958 silc_server_new_client when the username is initially set
1959 as nickname, so it must be checked to be valid nickname.
1960 Affected file silcd/packet_receive.c.
1962 * The nickname length is now taken from the packet for real
1963 and not trusted to strlen() since it clearly can return
1964 wrong length for nickname including bad characters. This
1965 also applies to channel names. Affected file silcd/command.c.
1967 * Removed the lib/silcsilm/modules directory. Modules are now
1968 compiled into the lib/silcsim. Fixed the copying of the
1969 modules to follow symbolic links in Makefile.am.pre.
1971 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1973 * Fixed silc_string_regexify list creation. Fixes bugs with
1974 BAN and INVITE commands in server. The affected file is
1975 lib/silcutil/unix/silcunixutil.c.
1977 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1979 * Removed the command destructor entirely from the server's
1980 command and command reply routines. It is not needed, and
1981 its usage was buggy and caused crashes. Affected files are
1982 silcd/command[_reply].[ch].
1984 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1986 * Cancel protocol and NULL sock->protocol if timeout
1987 occurred during protocol. Affected file silcd/server.c.
1989 * Cancel protocol timeouts always before calling the final
1990 callback, to assure that after final callback is called
1991 no other state will be called for the protocol anymore.
1992 Affected file silcd/protocol.c.
1994 * Print error log if incoming connection configuration could
1995 not be found. Affected file silcd/server.c.
1997 * Fixed JOIN command to correctly save the founder mode
1998 to the client on normal SILC server, when the channel
1999 was created by the router. Affected file silcd/command.c.
2001 * Fixed LIST command (hopefully) to send correct reply
2002 packets. Affected file silcd/command.c.
2004 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2006 * The silc_packet_receive_process now returns FALSE if the
2007 read data was invalid packet, and TRUE if it was ok.
2009 The server now checks that if unauthenticated connection
2010 sends data and its processing fails the server will close
2011 the connection since it could be a malicious flooder.
2013 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
2015 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2017 * Make sure the warning about error opening a log file is
2018 printed only once and not everytime it fails (produces
2019 too much useless log). Affected file lib/silcutil/silclog.c.
2021 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2023 * Made the silc_server_daemonise() function more readable.
2024 Affected file silcd/server.c.
2026 * Pid file is now optional, the user may comment it out from
2027 the config file. Removed define SILC_SERVER_PID_FILE, we
2028 don't need a default any longer. Affected file
2029 configure.in.pre, lib/Makefile.am.pre.
2031 * Make some use of the pid file. The server now dies at startup
2032 if it detects a valid pid file on his path. The server would
2033 die anyway in this circumstance, because of the bind() failure.
2034 Affected file silcd/silcd.c.
2036 * No longer compiling lib/dotconf.
2038 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2040 * Fixed JOIN command parsing not to crash. Affected file
2041 lib/silcclient/command.c.
2043 * Fied the NICK_CHANGE notify to add the new client entry
2044 even it is resolved. This removes an <[unknown]> nick
2045 thingy bug in the client. Affected file is
2046 lib/silcclient/client_notify.c.
2048 * Do not try to allocate 0 bytes (efence does not like it)
2049 in lib/silccore/silccomand.c when encoding payload.
2051 * Do not take IRCNICK as nickname in Irssi SILC client since
2052 it is not possible to set nickname before hand connecting
2053 the server (TODO has an entry about adding auto-nicking
2056 * Changed the silc_server_command_pending to check whether
2057 there already exists an pending entry with the specified
2058 command, command identifier and pending callback. This is
2059 to fix IDENTIFY and WHOIS related crashes that may register
2060 multiple pending commands with same identifier. Affected
2061 file silcd/command.c.
2063 * Fixed the server to reconnect to the router even if it
2064 was already reconnecting and EOF was received. This to
2065 fix a possibility that the server wouldn't ever try to
2066 auto-reconnect to the router. Affected file silcd/server.c.
2068 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2070 * Fixed the server's password authentication to use the
2071 length of the locally saved password, and not the one
2072 sent in the packet. Affected file silcd/protocol.c.
2074 * Fixed same password authentication problem in the
2075 Authentication Payload handling routines in
2076 lib/silccore/silcauth.c.
2078 * Yet another password authentication problem fixed with
2079 channel password handling in silcd/command.c.
2081 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2083 * If first character of string in silc_parse_userfqdn is '@'
2084 then do not parse it. Affected file is
2085 lib/silcutil/silcutil.c.
2087 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2089 * Fixed minor bug in IDENTIFY command reply sending, which
2090 caused various weird problems during JOIN when it was
2091 resolving names for users. Affected file silcd/command.c.
2093 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2095 * Fixed the IDENTIFY command reply sending to chech better valid
2096 clients. It was possible to send incomplete list of replies.
2097 Affected file silcd/command.c.
2099 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2101 * Added silc_client_command[s]_[un]register functions now to
2102 dynamically register the commands in client library. Removed
2103 the static table of commands. This allows the client library
2104 to call commands without causing the application to know about
2105 what commands library has called.
2107 Removed the INFO command reply kludge to detect when the command
2108 was called by library. Now library use its own command reply
2109 function for INFO command.
2111 Added function silc_client_command_call to call a command.
2112 Application can use it to call command, not access the structure
2115 Now all commands that are sent by the client library (not
2116 explicitly sent by application) use own command reply functions.
2118 Affected files around lib/silcclient/ and in
2119 irssi/src/silc/core/.
2121 * Fixed the WHOIS command reply sending to chech better valid
2122 clients. It was possible to send incomplete list of replies.
2124 Fixed the WHOIS and IDENTIFY to send the request to router
2125 if normal server did not do it and did not find any results.
2127 Affected file silcd/command.c.
2129 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2131 * Moved the internal data from SilcClient context into its
2132 own file, not accesible to application. Affected files
2133 lib/silcclient/client.h and lib/silcclient/client_internal.h,
2134 and other files in client library.
2136 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2138 * Added doc/examples installation target in Makefile.am.pre.
2141 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2143 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
2144 commands the found client entry will be removed from the
2145 cache, after notifying application about the error. Affected
2146 file lib/silcclient/command_reply.c.
2148 * Changed the /MSG to check for exact nickname user gave, and
2149 not let `nick' match `nick@host' if it is only one found. Now,
2150 user must type the exact nickname (like nick@host2) even if
2151 there are no more than one same nicks found. This is to avoid
2152 a possibility of sending nickname to wrong nickname since
2153 `nick' could match `nick@host'. Affected file is
2154 irssi/src/core/silc-servers.c.
2156 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2158 * Do not print "you are now server operator" or similar when
2159 giving /away command. Affected files are
2160 irssi/src/silc/core/client_ops.c, silc-servers.h.
2162 * Made the silc_server_command_pending_error_check to send
2163 the same command reply payload it received back to the
2164 original sender of the command. This way all arguments
2165 that was received by the server will be received by the
2166 client too. Affected file silcd/command.c.
2168 * Added the silc_idcache_add to return the created cache entry
2169 to a pointer. Affected file lib/silccore/silcidcache.[ch].
2171 * Add global clients to expire if they are not on any channel.
2172 This is because normal server will never know if they signoff
2173 if they are not on any channel. The cache expiry will take
2174 case of these entries. This is done by normal servers only.
2175 The affected files are silcd/command_reply.c,
2176 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
2178 * If server receives invalid ID notification for WHOIS or
2179 IDENTIFY and the ID exists in the lists, it is removed.
2180 Affected file silcd/command_reply.c.
2182 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
2183 in client then client entry that it matches is searched and
2184 the nickname is printed on the screen for user. Affected
2185 file irssi/src/silc/core/client_ops.c.
2187 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2189 * Use cache entry expire time in the LIST command reply to
2190 purge old entries from the cache after the LIST command
2191 reply has been received. This way we don't have non-existent
2192 entries in the cache for too long. Affected file is
2193 silcd/command_reply.c.
2195 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2197 * If we are normal server, and we've not resolved client info
2198 in WHOIS or IDENTIFY from router, and it is global client,
2199 we'll check whether it is on some channel. If it is not
2200 then we cannot be sure about its validity and will resolve it
2201 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
2202 file silcd/command.c.
2204 * Search channel by name (if possible) rather than by ID
2205 in IDENTIFY command's command reply. Affected file is
2206 silcd/command_reply.c.
2208 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2210 * Distribute to the channel passphrase in CMODE_CHANGE notify.
2211 Updated specs and implemented it. Affected file silcd/command.c,
2212 silcd/packet_send.c and silcd/packet_receive.c.
2214 * Implemented the <founder auth> payload handling in the JOIN
2215 command. If provided all conditions for channel joining
2216 except requirement to provide correct passphrase can be
2217 overrided by the channel founder. Updated the protocol specs.
2218 Affected file silcd/command.c.
2220 Added support for founder auth in JOIN command in client
2221 library. Fixed the parsing of the JOIN command now to support
2222 all options as they should be. The affected file is
2223 lib/silcclient/command.c.
2225 * Optimized the WHOIS and IDENTIFY commands to send the request
2226 to router only if it includes nicknames or other names. If
2227 they include only IDs then check the local cache first before
2228 routing. Affected file is silcd/command.c.
2230 * Added channels topic announcements. Affected file is
2231 silcd/packet_receive.c and silcd/server.c.
2233 * Fixed the silc_server_send_notify_topic_set to really destine
2234 the packet to channel. Affected file silcd/packet_send.c.
2236 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
2237 library. Affected file lib/silcclient/client_notify.c.
2239 * Added UMODE announcements. Affected file silcd/server.c.
2241 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2243 * Memory leak fixes in:
2245 lib/silcutil/silcsockconn.c
2246 lib/silcske/silcske.c
2247 lib/silcske/groups.c
2249 lib/silccrypt/silcpkcs.c
2250 lib/silccore/silccommand.c
2251 lib/silccore/silcidcache.c
2256 * ROBOdoc documented the lib/silcske/groups.h file and a
2257 bit changed the interface for better.
2259 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2261 * Update the client entry context in the ID cache after
2262 nick change. Affected file lib/silcclient/command.c.
2263 Fixes the CUMODE command when regaining founder privileges,
2264 and a little WHOIS problem.
2266 * Fixed silc_net_gethostbyname to correctly call the
2267 inet_ntop. Affected file lib/silcutil/silcnet.c.
2269 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2271 * Added IPv6 support checking to the configure.in.pre, added
2272 also --enable-ipv6 option to override the check. Affected
2273 file configure.in.pre.
2275 * The silc_thread_create now calls the start function
2276 directly if threads support is not compiled in. Removes
2277 ugly #ifdef's from generic code. Affected files are
2278 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
2280 * Added silc_net_gethostby[name/addr]_async to asynchronously
2281 resolve. Affected files are lib/silcutil/silcnet.[ch].
2283 * Added support for rendering IPv6 based server, client and
2284 channel IDs. Affected file lib/silcutil/silcutil.c.
2286 * Added support for creating IPv6 based server IDs. Affected
2287 file is silcd/serverid.c.
2289 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2291 * Added silc_net_gethostby[addr/name] into the
2292 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
2293 routines. Added silc_net_is_ip[4/6]. Affected file is
2294 lib/silcutil/unix/silcunixnet.c. All routines that take
2295 address as argument now supports both IPv4 and IPv6 addresses.
2297 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2299 * Fixed LIST command reply sending in server. Affected file
2302 * Server now sends the kicker's client ID in the KICK notify
2303 to the kicked client. Affected file silcd/command.c.
2305 * The client library now parses the kickers client ID and
2306 UI displays it. Affected files lib/silcclient/client_notify.c
2307 and irssi/src/silc/core/silc-channels.c, module-formats.c.
2309 * Made all payload parsing function prototypes consistent.
2310 They all take now const unsigned char * and uint32 pair as
2311 the payload data instead of SilcBuffer. Changes all around
2312 the source tree. Other unsigned char* -> const unsigned char*
2313 changes around the tree as well.
2315 * Optimized SFTP client and server packet sending not to
2316 allocate new buffer for each packet but to recycle the
2317 first allocated buffer. Affected files are
2318 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
2320 * Optimized the SFTP client to use SilcList instead of
2321 SilcDList for requests, because it is faster. Affected file
2322 is lib/silcsftp/sftp_client.c.
2324 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
2325 into lib/silccore/silcid.[ch].
2327 Renamed silcpayload.[ch] into silcargument.[ch].
2329 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2331 * If client entry is deleted with active key agreement
2332 session, abort the session.
2334 The silc_client_abort_key_agreement now calls the completion
2335 callback with new SILC_KEY_AGREEMENT_ABORTED status.
2337 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
2340 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2342 * Don't use __restrict in older GCC's. Affected file is
2343 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
2345 * silc_net_localhost now attempts to reverse lookup the
2346 IP/hostname. Affected file lib/silcutil/silcnet.c.
2348 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
2349 command. It can be used to gain founder privileges at
2350 the same time when joining the channel.
2352 Defined that the SILC_NOTIFY_TYPE_KICKED send the
2353 kicker's client ID as well. Updated protocol specs.
2355 Defined that the server must send SILC_COMMAND_IDENTIFY
2356 command reply with error status to client who sent
2357 private message with invalid client ID.
2359 Updated the protocol specification.
2361 * Added silc_server_send_command_reply to send any
2362 command reply. Affected file silcd/packet_send.[ch].
2364 * Added silc_id_payload_encode_data to encode ID payload
2365 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
2367 * The server now send IDENTIFY command reply with error
2368 status if client ID in private message is invalid. Affected
2369 file silcd/packet_receive.c.
2371 * Save the server key file with server's IP address in
2372 the filename instead of hostname. The affected file is
2373 irssi/src/silc/core/client_ops.c.
2375 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2377 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
2380 * Added libtool support for compiling shared objects in
2381 lib/silcsim. Affected file configure.in.pre and
2382 lib/silcsim/Makefile.am. Original patch by cras.
2384 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2386 * Pid file configuration, and server's config file fixes
2387 patch by toma. Updated CREDITS file.
2389 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2391 * Fixed silc_client_channel_message to not try to decrypt
2392 the message twice if it resolved the destination client
2393 information. This could cause of dropping one channel
2394 message. Affected file lib/silcclient/client_channel.c.
2396 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2398 * Added silc_client_run_one into lib/silcclient/silcapi.h and
2399 lib/silcclient/client.c. This function is used when the SILC
2400 Client is run under some other scheduler, or event loop or
2401 main loop. On GUI applications, for example this may be
2402 desired to used to run the client under the GUI application's
2403 main loop. Typically the GUI application would register an
2404 idle task that calls this function multiple times in a second
2405 to quickly process the SILC specific data.
2407 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2409 * Fixed silc_server_drop() for dropping the supplementary
2410 groups as well, this could cause a security hole on some
2413 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2415 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
2418 * Write PID file after dropping privileges. Added -F option
2419 to run server on foreground. A patch by debolaz.
2420 Affected files silcd/server.c, silcd/silcd.c.
2422 * Fixed MOTD to return the MOTD file server name. Affected
2423 file silcd/command.c.
2425 * Added INFO command reply handling to the Irssi SILC Client.
2426 Affected file irssi/src/silc/core/client_ops.c.
2428 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2430 * Fixed the silc_idcache_list_* routines to really support
2431 the dynamic list. Fixes a crash. Affected file is
2432 lib/silccore/silcidcache.c.
2434 * Fixed the LIST command reply to really call LIST command's
2435 pending callbacks. Affected file silcd/command_reply.c.
2437 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2439 * Update conn->local_entry->nickname after giving NICK
2440 command. Affected file lib/silcclient/command.c.
2442 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
2444 * Added the [pid] option to the silcd configuration file
2446 Affected files: serverconfig.[ch] and silcd.c
2448 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2450 * Save fingerprint in WHOIS command reply in server.
2451 Affected file silcd/command_reply.c.
2453 * Fixed NICK commands pending callback registration.
2454 Affected file lib/silcclient/command.c.
2456 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2458 * Use ++server->cmd_ident when sending commands in server,
2459 instead of random number. Affected file silcd/command.c.
2461 * Fixed GETKEY command reply to call actually GETKEY pending
2462 command callbacks. Affected file silcd/command_reply.c.
2464 * A bit stricter check for nicknames. Check for same nickname
2465 in NICK command also. Affected file silcd/command.c.
2467 * Do not call INFO command everytime client ID changes, only
2468 during first connecting. Affected file lib/silcclient/client.c.
2470 * Set the new nickname only after successful command reply for
2471 NICK command is returned by server. Affected file
2472 lib/silcclient/command.c.
2474 * Remove nicknames from nicklist during server_signoff notify.
2475 Should fix /NAMES bit more. The affected file is
2476 irssi/src/silc/core/silc-channels.c.
2478 * Added `fingerprint' field to the SilcIDListData in the
2479 silcd/idlist.h to hold the fingerprint of the client's
2482 Send the fingerprint of the client's public key in WHOIS
2485 Affected files silcd/command.c, and silcd/idlist.[ch].
2487 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
2488 create fingerprint from given data.
2490 * Show the fingerprint of the client's public key in WHOIS.
2491 Affected files irssi/src/module-formats.[ch] and
2492 irssi/src/silc/core/client_ops.c.
2494 * Format the multiple same nicknames also during JOIN and
2495 NICK_CHANGE notifys. Affected file is
2496 lib/silcclient/client_notify.c.
2498 * Do not print error on screen for invalid private message
2499 payload since it can come if someone is sending private
2500 messages with wrong key. Affected file
2501 lib/silccore/silcprivate.c.
2503 * Fixed multiple concurrent /PING crash. Affected file
2504 lib/silcclient/command.c.
2506 * Changed the wrong ID encoding. All IP addresses must be
2507 in MSB first order in encoded format. They were encoded
2508 wrong and was in LSB format. Affected files are
2509 silcd/serverid.c, lib/silcutil/silcutil.c.
2511 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
2513 * Call the `connect' client operation through the scheduler
2514 in case of error. Affected file lib/silcclient/client.c.
2516 * Call the `failure' client operation even if the error
2517 occurred locally during a protocol. Affected file is
2518 lib/silcclient/protocol.c.
2520 * Added support of sending LIST command to router from normal
2521 server. This way normal server can get list of all channels
2522 in the network too. Fixed the channel list sending in the
2523 server too. Affected files are silcd/command.c, and
2524 silcd/command_reply.[ch].
2526 * Added silc_server_update_channels_by_server and
2527 silc_server_remove_channels_by_server. They are used during
2528 disconnection of primary router and in backup router protocol.
2529 Affected file silcd/server_util.[ch], silcd/server.c and
2530 silcd/server_backup.c.
2532 * Fixed channel adding to global list in IDENTIFY command
2533 reply in server. Affected file silcd/command_reply.c.
2535 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2537 * If the incoming packet type is REKEY or REKEY_DONE process
2538 that packet always synchronously. Fixes yet another MAC
2539 failed error on slow (dialup) connections. Affected file
2540 lib/silcclient/client.c and silcd/server.c.
2542 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2544 * Call check_version SKE callback for initiator too. Affected
2545 file lib/silcske/silcske.c.
2547 * Implemented fix for security hole found in the SKE that was
2548 fixed in the specification few days back; the initiator's
2549 public key is now added to the HASH value computation.
2550 Added backwards support for the old way of doing it too, for
2551 old clients and old servers. Affected file is
2552 lib/silcske/silcske.c.
2554 * Enabled mutual authentication by default in SKE. If initiator
2555 is not providing mutual authentication the responder will
2556 force it. This will provide the proof of posession of the
2557 private key for responder. The affected files are
2558 lib/silcclient/protocol.c and silcd/protocol.c.
2560 * Do not cache anymore the server's public key during SKE.
2561 We do mutual authentication so the proof of posession of
2562 private key is done, and if the server is authenticated in
2563 conn auth protocol with public key we must have the public
2564 key already. Affected file silcd/protocol.c.
2566 * Added new global debug variable: silc_debug_hexdump. If
2567 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
2568 file lib/silcutil/silclog.[ch].
2570 * Fixed compilation warning due to char * -> const char *.
2571 Affected files lib/silcutil/silcnet.h, and
2572 lib/silccore/silcauth.[ch].
2574 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2576 * Fixed CMODE command when new channel key was created. If
2577 the creation failed the old key was removed. Next time giving
2578 same command would crash the server since the old key was
2579 freed already. Affected file silcd/command.c.
2581 * Fixed the silc_server_announce_get_channels to not crash
2582 on reconnect. Affected file silcd/server.c.
2584 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2586 * Added silc_log_set_debug_string function to set a regex
2587 string to match for debug output. Only the function names,
2588 or filenames matching the given debug string is actually
2589 printed. This way it is possible to filter out those debug
2590 strings that user is not interested in.
2592 Fixed a bug in silc_string_regexify.
2594 Affected files lib/silcutil/silclog.[ch], and
2595 lib/silcutil/unix/silcunixutil.c.
2597 * Changed the -d options in both server and Irssi SILC client
2598 to take the debug string as argument. Affected files
2599 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
2601 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2603 * Added silc_hash_babbleprint to create a Bubble Babble
2604 Encoded fingerprint. The encoding is developed by Antti
2605 Huima (draft-huima-babble-01.txt), and it creates human

2614 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2616 * Fixed a security problem found in SKE. The initiator's
2617 public key too is now added to the HASH hash value creation
2618 which is signed by the responder to create the SIGN value.
2619 This will prevent anyone in the middle to lie to the responder
2620 about the initiator's public key. If this is done now, the
2621 man in the middle will get caught. Updated the protocol
2624 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2626 * Better installation directory handling. Configure module
2627 paths and other paths automatically to example_silc* files
2628 in doc/. A patch by toma.
2630 * Fixed compiler warning from MPI library, and from SILC RNG.
2633 * Added SILC_SERVER_PID_FILE to define the pid file for server.

2660 * Added silc_pkcs_public_key_compare to compare two
2661 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
2663 * Check that the client who set the founder mode on the
2664 channel is the same client that is giving the founder
2665 mode to itself. It is done by comparing the saved public
2666 key (it is saved even in the authentication is passphrase).

2674 * Process the DISCONNECT packet through scheduler in the
2675 client library. Affected file lib/silcclient/client.c.
2677 * Fixed the silc_client_packet_parse to not to increase
2678 the packet sequence number if the conn->sock and the
2679 current socket connection is not same. This can happen
2680 for example during key agreement when the conn includes
2681 multiple socket connections (listeners). Affected file
2682 lib/silcclient/client.c.
2684 * The sender of the file transfer request now provides also
2685 the pointer (listener) for the key exchange protocol. If
2686 the listener cannot be created then it sends empty key
2687 agreement and lets the receiver provide the listener.
2689 Added `local_ip' and `local_port' arguments to the
2690 silc_client_file_send. If they are provided they are used,
2691 if not then it will attempt to find local IP address, if
2692 not found or bind fails then the remote client will provide
2695 Affected files are lib/silcclient/client_ftp.c and
2696 lib/silcclient/silcapi.h.
2698 * Extended the FILE SEND command to support defining the
2699 local IP and port for key exchange listener. They are

2704 * Defined to WHOIS command reply the sending of fingerprint
2705 of the client's public key (if the proof of posession of the
2706 corresponding private key is verified by the server).
2707 Updated to the protocol specification.
2709 * Added support of receiving the client's public key's
2710 fingerprint in command reply in client library. Affected
2711 file is lib/silcclient/command_reply.c, and
2712 lib/silcclient/idlist.[ch].
2714 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>

2767 client library. Affected file lib/silcclient/client_prvmsg.c.
2769 * Do not actually remove the client directly from ID cache
2770 during SERVER_SIGNOFF, but invalidate it. This way we
2771 preserve the WHOWAS info for the client. Affected file
2772 silcd/server_util.c.
2774 * Fixed SERVER_SIGNOFF notify handling in the server. The
2775 server is now able to process incoming SERVER_SIGNOFF notify
2776 for a server that it doesn't even know about. It will remove
2777 the clients provided in the notify. Affected file
2778 silcd/packet_receive.c.
2780 * Check for partial packet in data queue after every packet that
2781 was found from the queue. Return and wait for more data if
2782 there is partial data in queue. Affected file is
2783 lib/silccore/silcpacket.c.
2785 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2787 * Added SilcClietFileError enum to indicate error in
2788 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT

2800 irssi/src/fe-common/silc/module-formats.[ch].
2802 * Wrote a help file for FILE command.
2804 * Added silc_rng_global_get_byte_fast to get not-so-secure
2805 random data as fast as possible. Random data is read from
2806 /dev/urandom if available and from the SILC RNG if not
2807 available. It is used in padding generation. Affected file
2808 lib/silccrypt/silcrng.[ch].
2810 * All packets in client library are now processed synchronously.
2811 Optimized packet processing a lot. Affected file
2812 lib/silcclient/client.c.
2814 * All server connection packets are processing synchronously
2815 now in server, to optimize packet processing. Affected file
2818 * Include files are installed now only in Toolkit distribution
2819 if make install is given. Affected files: all Makefile.am's.
2821 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2823 * Assure that silc_client_notify_by_server_resolve does not
2824 resolve the client information multiple times. If it cannot
2825 be found by the first it cannot be found at all. Affected
2826 file lib/silcclient/client_notify.c.
2828 * Fixed WHOWAS command reply calling. Affected file
2829 lib/silcclient/command_reply.c.
2831 * Removed all references to silc_idlist_get_client from the
2832 Irssi SILC client since that call is internal call used by
2833 the library. The Irssi SILC client will use now client
2834 retrieval functions found in silcapi.h.
2836 * Fixed a bug in resolving nickname info before sending
2837 private message. It used freed memory. Affected file
2838 irssi/src/silc/core/silc-servers.c.

2859 * Added silc_net_localip to return local host's IP address.
2860 Affected file lib/silcutil/silcnet.[ch].
2862 * If key exchange or rekey protocol is active for a connection
2863 parse all packets syncronously since there might be packets
2864 in packet queue that we are not able to process without first
2865 processing packets before them. Affected file silcd/server,
2866 lib/silcclient/client.c.
2868 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2869 whether library should continue processing the packet.
2870 Affected file lib/silccore/silcpacket.h.
2872 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and

2916 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
2917 is incomplete and is being resolved, it won't be resolved
2920 Make sure also that USERS command reply does not resolve
2921 twice information. Affected file is
2922 lib/silcclient/command_reply.c.
2924 Make sure that silc_client_get_clients_by_list does not
2925 resolve twice same information.
2927 * Check for valid client->id in the silc_server_free_client_data.
2928 Affected file silcd/server.c.
2930 * Fixed /GETKEY nick@server not to crash if the server entry
2931 is not found. Affected file lib/silcclient/command.c.
2933 * Fixed the silc_server_check_cmode_rights to check the

2941 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2943 * Call the silc_server_udpate_servers_by_server in the
2944 primary router that comes back online in the backup resuming
2945 protocol. Otherwise it routes packets wrong. Affected file
2946 silcd/server_util.[ch], silcd/server_backup.c.
2948 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2950 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2951 lib/silcutil/silcbuffmt.[ch].
2953 * Redefined the SILC packet header to include the padding
2954 length. Affected file lib/silccore/silcpacket.[ch].
2956 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2957 length for maximum padding up to 128 bytes). Affected
2958 file lib/silccore/silcpacket.h.
2960 * Removed all backwards support for old 0.5.x MAC thingies.
2961 The SILC packet header change makes it impossible to be
2962 backwards compatible.
2964 * Send the ENDING packet with timeout in the backup resuming
2965 protocol. This is to assure that all routers has connected
2966 to the primary router. Affected file silcd/server_backup.c.
2968 * Changed the RNG to take the first IV from random data. It
2969 used to take it from zero actually. Changed the RNG also
2970 to use /dev/urandom during session. /dev/random is used
2971 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2973 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2975 * Changed the SILC packet header to have the first two bytes
2976 (the packet length) encrypted. Affected files aroung the
2977 code tree, lib/silccore/silcpacket.[ch]. Removed the
2978 SilcPacketCheckDecrypt callback. It is not needed anymore
2979 since the silc_packet_receive_process will determine now
2980 whether the packet is normal or special.
2982 * Implemented the unidirectional MAC keys. Affected files
2983 lib/silcske/silcske.c, silcd/protocol.c and
2984 lib/silcclient/protocol.c.

2991 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2993 * Allow backup router to announce servers. All servers
2994 announced by backup router are added to the global list
2995 automatically. Update hte server's socket to our primary
2996 router also when backup router announces a server.
2997 Affected file silcd/packet_receive.c.
2999 * Do not update the client->router in the function
3000 silc_server_udpate_clients_by_server if the client is on
3001 global list. We might fail to find any specific server
3002 for locally connected clients and local cell clients. They
3003 should still use the `from' and not `to' as client->router.
3004 This fixes backup router resuming protocol. Affected file
3005 silcd/server_util.c.
3007 * Decrease channel statistics count only if the channel
3008 deletion worked. Affected files are silcd/server.c and
3009 silcd/server_util.c.
3011 * Added silc_server_update_servers_by_server to update origin
3012 of all server entries. Used during backup router protocol.

3021 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3023 * Assure that router cannot reroute the same channel message
3024 to the sender. Affected file silcd/packet_receive.c.
3026 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3028 * Made better checks that the channel message is not sent
3029 to the router it came from. Affected file is
3030 silcd/packet_send.c. Fixed memory leak too.
3032 * Announce informations for incoming router connection, but
3033 only after checking if it is replaced by backup router.
3034 Affected file silcd/packet_receive.c.
3036 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3038 * Fixed the backup resuming protocol to work in multiple
3039 router environment. Affected file silcd/server_backup.c.
3041 * Route packet only to one router in the function
3042 silc_server_packet_send_to_channel. Affected file is
3043 silcd/packet_send.c.
3045 * Fixed silc_server_send_notify_dest to set the broadcast
3046 flag. Fixed the silc_server_send_notify_topic to actually
3047 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
3048 Affected file silcd/packet_send.c.
3050 * Changed the SFTP Filesystem interface. Changed the
3051 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
3052 the filesystem operation function. The SilcSFTPFilesystem
3053 is now a context that is allocated by all filesystem allocation
3054 functions and it already includes the operations structure
3055 and filesystem specific context. It is given as argument
3056 now to the silc_sftp_server_start. This made the interface
3057 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
3058 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
3060 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3062 * Changed the backup router adding and getting interfaces
3063 in the server. The router that will be replaced by the
3064 specified backup router is now sent as argument. Affected
3065 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
3068 * Added silc_net_addr2bin_ne to return the binary form of
3069 the IP address in network byte order. Affected files
3070 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
3072 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3074 * Check for existing server ID in silc_server_new_server
3075 and in silc_server_connect_to_router_final and remove the
3076 old entry if it exists. Affected file silcd/packet_receive.c,
3079 * Send the channel message always to only one router, either
3080 in upstream or downstream. Affected file is
3081 silcd/packet_send.c.
3083 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3085 * Wrote the definition of the backup resuming protocol to the
3086 protocol specification.
3088 * Removed one redundant channel key generation from normal
3089 server during joining procedure. Removed one redundant
3090 channel key sending from server to router during joining
3091 procedure. Affected file silcd/command.c.
3093 * Made minor bugfixes to the backup router resuming protocol.
3094 Affected file silcd/server_backup.c, server.c.

3103 resume the primary router position in the cell after the
3104 primary router comes back online. Affected files
3105 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
3106 and silcd/server_util.[ch].
3108 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3110 * Sleep two (2) seconds after sending QUIT command to server.
3111 Affected file lib/silcclient/command.c.
3113 * Assure that if outgoing data buffer is pending do not force
3114 send any data. Affected file silcd/packet_send.c.
3116 * Assure that if outgoing data buffer is pending do not force
3117 send any data. Affected file lib/silcclient/client.c.
3119 * Implemented the backup router support when the primary router
3120 goes down. The servers and routers can now use the backup
3121 router as new primary router without loosing connectivity.
3123 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3125 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
3126 in the server to indicate disabled entry. All data read
3127 from the connection will be ignored and no data is sent
3128 for entry that is disabled. Affected files are
3129 silcd/idlist.h, silcd/server.c.
3131 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3133 * Created SFTP client and server test programs in the
3134 lib/silcsftp/tests directory.
3136 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3138 * Implemented memory filesystem (virtual filesystem) for
3139 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
3142 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3144 * Implemented the SFTP (SSH File Transfer Protocol) to the
3145 lib/silcsftp. It includes SFTP client and SFTP server
3148 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3150 * Moved lib/silccore/silcprotocol.[ch] to the
3151 lib/silcutil library.
3153 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
3154 take variable argument list pointer as argument. Affected
3155 file lib/silcutil/silcbuffmt.[ch].
3157 * Added silc_buffer_set function that is used to set data
3158 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
3159 Affected file lib/silcutil/silcbuffer.h.
3161 * Changed various routines in the core library to use the new
3162 silc_buffer_set instead of allocating new buffer only for
3165 * Added 64-bit value formatting and unformatting support to the
3166 silc_buffer_[un]format routines. Affected file is
3167 lib/silcutil/silcbuffmt.[ch].
3169 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
3170 to includes/bitmove.h.
3172 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3174 * Fixed channel user mode saving in client library. Affected
3175 file lib/silcclient/command[_reply].c.
3177 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3179 * Defined the file transfer to the SILC Protocol. Added
3180 new packet type SILC_PACKET_FTP and defined File Transfer
3181 Payload. The mandatory file transfer protocol is SFTP
3182 (SSH File Transfer Protocol). Affected file in addition
3183 of the internet draft is lib/silccore/silcpacket.h.
3185 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
3186 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
3187 is used as part of backup router protocol when the primary
3188 router of the cell is back online and wishes to resume
3189 the position as primary router.
3191 * Redefined the MAC generation keys in the protocol. The
3192 same key is not used anymore in both direction. Both
3193 direction will now use different keys for sending and
3194 receiving. This fixes a potential security flaw. This
3195 change causes incompatibilities in the protocol.
3197 * Redefined also the MAC computation from the packet.
3198 An packet sequence number is now added to the MAC
3199 computation. This prevents possible replay attacks against
3200 the protocol. This change too causes incompatibilities
3203 Added `sequence' field to the SilcPacketContext to hold
3204 the current sequence number for the packet.
3206 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3208 * Added `created' field to the SilcIDListData in the file
3209 silcd/idlist.h to indicate the time when the entry was
3212 * Added `created' field to the SilcChannelEntry too. Affected
3213 file silcd/idlist.h.
3215 * Added `creation_time' aguments to all the announcement functions
3216 in the server. If it is provided then only the entries that
3217 was created after the provided time frame are actually
3218 announced. Affected file silcd/server.[ch].
3220 * The protocol says that the Channel ID's IP address must be
3221 based on the router's IP address. Added check for this in
3222 the silc_server_new_channel when processing incoming New Channel
3223 Payload. Affected file silcd/packet_receive.c.
3225 * Print out the correct version with --version in SILC client.
3226 Affected file irssi/src/silc/core/silc-core.c.
3228 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3230 * Fixed WHOWAS command to check for completnes of the client
3231 entry always, not just when the command is coming from client.
3232 Affected file silcd/command.c.
3234 * Added new function silc_server_packet_queue_purge to purge the
3235 outgoing data queue to the network. After the function returns
3236 it is guaranteed that the outgoing packet queue is empty.
3237 Affected file silcd/packet_send.[ch].
3239 * Purge the outgoing packet queue in the rekey protocol's final
3240 callback to assure that all rekey packets go to the network
3241 before quitting the protocol. Affected file silcd/server.c.
3243 * Added silc_client_packet_queue_parse as similar function as
3244 in server to the client library. The affected file is
3245 lib/silcclient/client.c.
3247 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3249 * Splitted silcd/server.c and created silcd/server_util.[ch]
3250 for utility functions.
3252 * Added new socket flag SILC_SF_DISABLED to indicate that the
3253 connection is open but nothing can be sent to or received from
3254 the connection. Affected file lib/silcutil/silsockconn.[ch].
3255 The checking for disabled socket is checked in the low level
3256 silc_socket_write and silc_socket_read functions.
3258 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3260 * Allow only nicknames and channel names that fits into the
3261 7-bit unsigned char ASCII set. Affected file silcd/command.c.
3263 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3265 * When processing JOIN command reply in server check that if
3266 the channel exists in our global list we'll move it the local
3267 list. Affected file silcd/command_reply.c.
3269 * Fixed the check whether client is joined on the channel already
3270 in JOIN command. Affected file lib/silcclient/command.c.
3272 * Fixed the JOIN command reply to check whether the channel
3273 already exists. Affected file lib/silcclient/command_reply.c.
3275 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3277 * Added silc_ske_status_string to map the SKE error numbers
3278 to readable strings. The affected files are
3279 lib/silcske/silcske[_status].[ch].
3281 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3283 * Do not show the private channels on the WHOIS channel list
3284 as it is not allowed by the protocol. The affected file is
3287 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3289 * Assure that the packet length digged from the actual packet
3290 is something sensible in the silc_packet_decrypt_rest_special
3291 in lib/silccrypt/silcpacket.c.
3293 * Free and NULL the allocated pointer in silc_hmac_alloc if
3294 the HMAC allocation fails. The affected file is
3295 lib/silccrypt/silchmac.c.
3297 * Print the selected security properties to the log files in
3298 the server. Affected file silcd/protocol.c.
3300 * Add SKE's reference counter even if calling the completion
3301 callback manually. Otherwise it goes negative, although it
3302 does not cause any problems. The affected file is
3303 lib/silcske/silcske.c.
3305 * Remove the client entry with short timeout after giving the
3306 KILL command. Affected file lib/silcclient/command.c.
3308 * Fixed to send error reply in WHOIS and IDENTIFY commands in
3309 case all found clients are already disconnected (WHOWAS would
3310 found them) in the server. Affected file silcd/command.c.
3312 * Update the last_receive (time of last data received) to be
3313 updated only when received private or channel message so that
3314 the idle time showed in WHOIS makes more sense.
3316 * Added boolean field `valid' in to the SilcClientEntry in the
3317 client library to indicate whether the entry is valid or not.
3318 This fixes the nickname change bug on channel when changing
3319 the nickname to be same than the old (like nick to Nick) the
3320 nickname formatter doesn't set the new nick anymore to Nick@host.
3321 Affected file lib/silcclient/idlist.[ch].
3323 * Now actually fixed the nickname changing on disconnection.
3324 Added new function silc_change_nick to the Irssi SILC Client.
3325 Affected file irssi/src/silc/core/client_ops.c,
3326 irssi/src/silc/core/silc-nicklist.[ch].
3328 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3330 * Check that the public key exists in the GETKEY command before
3331 trying to encode it. Affected file silcd/command.c.
3333 * Print some notifications on received public keys with GETKEY
3334 command in the Irssi SILC Client. Affected files are
3335 irssi/src/fe-common/silc/module-formats.[ch],
3336 irssi/src/silc/core/client_ops.c.
3338 * Use IDENTIFY command to resolve the server information in the
3339 GETKEY command instead of INFO command. Affected file
3340 lib/silcclient/command.c.
3342 * All command reply functions in the client library now calls
3343 the pending command reply callbacks even if an error has
3344 occurred. The server has done this a long time and now it was
3345 time to move the client library to this as well. Now all
3346 errors can be delivered back to the pending command reply
3347 callbacks if necessary. Affected files are
3348 lib/silcclient/command[_reply].[ch].
3350 * Change the nickname on disconnection back to the username
3351 because in reconnect the server will enforce it to it anyway.
3352 Affected file irssi/src/silc/core/silc-servers.c.
3354 * Fixed a config file parsing bug in the Irssi SILC client.
3355 Affected file irssi/src/silc/core/clientconfig.c.
3357 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3359 * When printing the channel mode on JOIN, verify that the
3360 channel key and channel's HMAC are valid. Affected file
3361 irssi/src/silc/core/client_ops.c.
3363 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3365 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
3366 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
3367 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
3369 * Removed channel key rekey task deleting from the function
3370 silc_server_save_channel_key. Affected file silcd/server.c.
3371 Added explicit timeout task context instead that is used to
3372 delete the task if we are registering a new task before the
3373 new task has elapsed.
3375 * When channel key rekey occurs the client library now saves
3376 the old channel key for a short period of time (10 seconds) and
3377 is able to use it in case some is still sending channel
3378 messages encrypted with the old key after the rekey. Affected
3379 file lib/silcclient/[idlist.h|client_channel.c].
3381 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3383 * Added check to the silc_server_new_id_real to not accept
3384 new ID if it is the sender's own ID. Affected file is
3385 silcd/packet_receive.c.
3387 * Assure that we do not announce ourself or the one we've
3388 sending our announcements when we're router and are announcing
3389 servers to our primary router. Affected file silcd/server.c.
3391 * Fixed silc_server_command_identify_check_client to assemble
3392 correct WHOIS packet. It send corrupted WHOIS packet and
3393 caused problem with router to router connections. Affected
3394 file silcd/command.c.
3396 Fixed also silc_server_command_whois_check the same way
3397 as for the IDENTIFY command.
3399 * Added new SilcIDListStatus to the server in the SilcIDListData
3400 structure. The status now includes the current status of
3401 the entry (like registered, resolved etc.). Affected file
3402 silcd/idlist.[ch]. Defined a bunch of different status types
3403 as well. This replaced the old boolean registered field as well.
3405 Added resolve_cmd_ident field to the SilcClientEntry structure
3406 too so that if the entry is for example being resolved so
3407 another command may attach to the same pending command reply
3408 without requiring to resolve the same entry again. This concept
3409 should optimize the WHOIS and the IDENTIFY resolving under
3410 heavy load by taking away unnecessary resolving for entries
3411 that are being resolved already.
3413 Added support for adding multiple pending commands for one
3414 command idenfier. Affected file silcd/command[_reply].[ch].
3416 * Fixed WHOIS and IDENTIFY save to remove the cache entry
3417 before deleting the data. Otherwise the hash table will have
3418 freed data in comparison functions. Affected file is
3419 silcd/command_reply.c.
3421 * Fixed silc_idlist_replace_client_id to add the new entry to
3422 the cache with NULL nickname. Otherwise there will be invalid
3423 memory as the nickname after the nickname is freed. Affected
3424 file silcd/packet_receive.c.
3426 * Fixed the silc_idlist_get_clients_by_hash. The entries was
3427 saved into wrong slots because the previous number of entries
3428 was not taken into account. Affected file silcd/idlist.c.
3429 Fixed same thing in silc_idlist_get_clients_by_nickname too.
3431 * If we are router and we receive JOIN notify to a channel that
3432 does not have any users then notified client is marked as the
3433 channel founder, as it is it. The affected file is
3434 silcd/packet_receive.c
3436 * Added to the extended hash table API's table_del_*ext functions
3437 the destructor as argument too, so that the caller can decide
3438 which destructor to use or whether to use destructor at all.
3439 Affected file lib/silcutil/silchashtable.[ch].
3441 * Fixed ID Cache purging. It actually deleted the entries from
3442 the hash table after the data was freed. The hash table ended
3443 up comparing freed memory. The affected file is
3444 lib/silccore/silcidcache.c.
3446 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3448 * Fixed Irssi SILC client's KILL command's HELP syntax.
3450 * The USERS command now resolves the detailed user information
3451 if the userinfo field is missing. Affected file is
3452 lib/silcclient/command_reply.c.
3454 * Do not print error in silc_file_read if the read file does
3455 not exist. Just silently return NULL. Affected file is
3456 lib/silcutil/silcutil.c.
3458 * Fixed the silc_log_output to not wine about NULL filename
3459 and to not create some bogus " " filename. Affected file is
3460 lib/silcutil/silclog.c.
3462 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3464 * Fixed various printing bugs on the user interface in the
3465 Irssi SILC Client. Minor changes that were forgotten from
3468 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3470 * Fixed the configure.in.pre and the compilation and distribution
3471 environment to support the new autoconf 2.52. That version is
3472 now required to compile the CVS trunk.
3474 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3476 * Renamed function silc_parse_nickname to silc_parse_userfqdn
3477 to generally parse user@fqdn format strings. Affected file
3478 lib/silcutil/silcutil.c.
3480 * Added nickname_format and nickname_force_format fields to the
3481 SilcClientParams structure. The first one defines the format
3482 for the nicknames that the library will enforce if the receives
3483 multiple same nicknames. The second one is boolean value and
3484 can be used to force the library to always enforce the format
3485 to the nicknames regardles whether there are multiple nicknames
3486 or not. This configurable formatting was employed to flexibly
3487 support accessing multiple nicknames from the user interface.
3488 The userinterface can now set the nicknames to what ever format
3489 they prefer. Affected file lib/silcclient/silcapi.h.
3491 Added function silc_client_nickname_format to the file
3492 lib/silcclient/idlist.c. It performs the nickname formatting.
3494 Added new field `hostname´ to the SilcClientEntry context.
3495 It holds the hostname of the client. Affected file is
3496 lib/silcclient/idlist.h.
3498 * Irssi SILC Client sets the nicknames in nick@hostn format.
3499 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
3500 irssi/src/silc/core/silc-core.c.
3502 The WHOIS printing now also shows both the real nickname and
3503 the formatted nickname so that user knows how to access the
3504 user if there are multiple same nicknames cached. Affected
3505 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
3506 printing formatting too to take the hostname now as a separate
3507 argument. The Affected file is
3508 irssi/src/fe-common/silc/modules-formats.[ch].
3510 * Changed the silc_client_get_clients_local to accept the formatted
3511 nickname as argument. It accepts the real nickname too but the
3512 formatted nickname can be used to find the true entry from
3513 multiple entries. Affected file lib/silcclient/silcapi.h and
3514 lib/silcclient/idlist.c.
3516 * Added nickname_format_parse field to the SilcClientParams.
3517 It is a callback function provided by the application to parse
3518 the nickname out of the formatted nickname string. The library
3519 calls it to get the nickname from the formatted string. Since
3520 the application generally knows better the format of the nickname
3521 string it parses it instead of the library, even though library
3522 encodes the formatted string. If the callback function is not
3523 provided then the library will use the string as is. The
3524 affected file is lib/silcclient/silcapi.h.
3526 * All the nickname strings passed to the client library in
3527 commands are now expected to be formatted nickname strings.
3528 If the command does not support the formatted nickname string
3529 it will assume that the sent string is the actual nickname.
3530 Affected file lib/silcclient/command.c.
3532 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3534 * Added public key authentication support to OPER and SILCOPER
3535 commands in the client library. Affected file is
3536 lib/silcclient/command.c.
3538 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3540 * Changed the get_auth_methdod client operation to be asynchronous.
3541 It can be async if the application resolves the authentication
3542 method from the server during the negotiation. Added new
3543 SilcGetAuthMeth completion callback that the application will
3544 call after resolving the authentication method.
3546 Added function silc_client_request_authentication_method that
3547 the application can use to resolve the authentication method
3548 from the server. Added also SilcConnectionAuthRequest callback
3549 that the library will call after the server has replied. The
3550 application can call this function if it does not know the
3551 current authentication method.
3553 Affected files are lib/silcclient/client.c and
3554 lib/silcclient/silcapi.h.
3556 * The Irssi SILC client now automatically resolves the authentication
3557 method incase any configuration information is not present (and
3558 currently there never is). The affected file is
3559 irssi/src/silc/core/client_ops.c.
3561 * Fixed public key authentication from the client library.
3562 Affected file lib/silcclient/protocol.c. Changed also the
3563 protocol specification about the public key authentication in
3564 the connection authentication protocol. The actual data to be
3565 signed is now computed with a hash function before signing.
3567 * Fixed the public key authentication from the server as well.
3568 Affected file silcd/protocol.c.
3570 * Removed the mlock()'s from the memory allocation routines.
3571 Affected file lib/silcutil/silcmemory.c. The ./configure does
3572 not check anymore for the mlock(). Affected file is
3575 * Fixed USERS command in server to allow the execution of the
3576 command for private and secret channels if the client sending
3577 the command is on the channel. Affected file silcd/command.c.
3579 * Fixed silc_client_get_clients_local to return the clients
3580 count correctly. It could return wrong value. Affected file
3581 lib/silcclient/idlist.c.
3583 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3585 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
3586 types. The assembler optimizations seemed not to like 64-bit
3587 data types. The assmebler optimizations thus are now enabled
3588 also for BSD systems as opposed to only enable them for Linux.
3590 * Do not check for threads at all on BSD systems. Affected
3591 file configure.in.pre.
3593 * Removed -n and -h options from the Irssi SILC Client since
3594 they are not used in silc.
3596 * Fixed the prime generation to assure that the first digit
3597 of the generated random number is not zero since our conversion
3598 routines does not like number strings that starts with zero
3599 digit. If zero digit is seen the random number is regenerated.
3600 This caused some corrupted RSA keys when the zero first digit
3601 was met. Affected file lib/silcmath/silcprimegen.c.
3603 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3605 * Fixed WIN32 configuration in the ./configure script.
3606 Fixed to include xti.h on environments that has it.
3607 Patches by Carsten Ilchmann and andrew.
3609 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3611 * Changed the silc_id_create_client_id to be collision
3612 resistant. It is now assured that there cannot be created
3613 two same client ID's. I suspect that some weird bugs in
3614 the server were actually caused by duplicate Client IDs.
3615 Affected file silcd/serverid.[ch]. A router receiving
3616 new ID now also assures and informs the sending server
3617 if the ID caused collision.
3619 * Changed the silc_id_create_channel_id to also assure that
3620 there are no collisions.
3622 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3624 * Statement about ignoring the Mutual Authentication flag when
3625 performing rekey with PFS was a bit misleading. It is ignored
3626 if it was set in the initial negotiation, it cannot be even
3627 set in the rekey. Fixed in the ke-auth draft. Started the
3628 new versions of the protocol drafts in the doc/.
3630 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3632 * Fixed a bug in silc_client_command_identify_save when saving
3633 new channel information. The channel name was no duplicated
3634 and caused crash on exit. Affected file is
3635 lib/silcclient/command_reply.c.
3637 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3639 * Fixed the getkey command handling in the server. Send just
3640 empty OK reply to the sender if the key could not be fetched
3641 (but everything else was ok, like the key just was not available).
3642 Changed the public key parameter to optional in the protocol
3643 specs so that empty OK reply can be sent. Affected file
3646 Added a message to Irssi SILC client to tell to user if the
3647 server did not return a public key.
3649 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3651 * Fixed a channel key regeneration bug. It registered new
3652 timeout tasks exponentially until all system resources were
3653 used. Affected file silcd/server.c.
3655 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3657 * Added the SILC Document generator to the scripts/silcdoc.
3658 It can be used to generate the Toolkit Reference Manual out
3659 of the source tree. Internally it will also use the RoboDoc
3660 generator now imported in util/robodoc.
3662 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3664 * Added couple of return's in rekey protocol if error orccurred
3665 during the protocol. The execution must be terminated.
3666 Affected file silcd/protocol.c. Also, terminate the protocol
3667 always with timeout.
3669 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3671 * The client's Client ID was created initally from the wrong
3672 nickname (it could have been in format nick@host) in the
3673 silc_server_new_client. Affected file silcd/packet_receive.c
3675 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3677 * Added some SILC_LOG_ERROR's to various error conditions
3678 if client could not be added to ID cache. Affected files
3679 silcd/packet_receive.c and silcd/server.c.
3681 * When client's sock->user_data is freed, NULL also the
3682 client->router and client->connection pointers. Added check
3683 for these pointers being NULL to various places around the
3684 code. Affected file silcd/server.c.
3686 * Added client->data.registered == TRUE checks to various
3687 places around the code to assure that unregistered client's
3688 are not handled when it is not allowed. Affected file
3691 * Added `bool registered' fields to all
3692 silc_idlist_[server|client]_get_* routines to indicate whether
3693 the fetched client needs to be registered or not. Affected
3694 file silcd/idlist.[ch].
3696 * Add your own entry as registered to the ID cache in the
3697 server. Affected file server.c.
3699 * Fixed a bug in silc_server_new_server. The SilcServer was
3700 set as the new server's context instead of SilcServerEntry.
3701 This naturally caused some weird bugs.
3703 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3705 * Do not delete the channel rekey task when adding it
3706 for in silc_server_create_channel_key.
3708 * Changed the silc_server_create_channel_key to return
3709 TRUE or FALSE to indicate the success of the channel key
3712 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3714 * Fixed MSVC++ project files and added missing files to

3717 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3719 * Do not add TCP_NODELAY flag if the operating system
3720 does not have it defined. Affected files are
3721 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3723 * Fixed buffer overflow from Irssi SILC Client. Affected
3724 file irssi/src/fe-common/core/themes.c.
3726 * Fixed double free in client library in the file
3727 lib/silcclient/client.c when disconnecting from server.
3729 * Applied double free patch from cras to Irssi SILC client.
3730 Affected files irssi/src/core/[modules/expandos].c
3732 * Fixed the disconnection handling to Irssi SILC Client.
3733 The application must call silc_client_close_connection
3734 in ops->connect client operation in case of failure of
3735 the connection. Affected file is
3736 irssi/src/silc/core/client_ops.c.
3738 * Do not set sock->protocol to NULL in the function
3739 silc_client_close_connection after executing the protocol's
3740 final callback since the sock might not be valid anymore.
3741 Affected file lib/silcclient/client.c.
3743 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3745 * Do not enable SILC_THREADS if the linking with libpthread
3746 did not happen. Affected file configure.in.pre.
3748 * Added notion to protocol specification that server must
3749 verify the sent authentication payload with CMODE when
3750 setting the channel founder key. Implemented it to the
3751 server. Affected file silcd/command.c.
3753 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3755 * Added _EXTRA_DIST SILC distribution variable to the
3756 distributions file. It is used to conditionally add extra
3757 files or directories to the specific distribution. Affected
3758 files ./prepare, Makefile.am.pre and distributions.
3760 Removed the `_' from the start of the distribution names.
3763 * Added README.WIN32 for instructions to compile the Toolkit
3766 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3768 * Fixed a double free in disconnection in the server. Affected
3769 file is silcd/server.c.
3771 * Fixed the lib/silcske/groups.c to work now also with GMP
3772 MP library. The string conversion did not work when using
3773 specific base and the base is indicated in the string as well.
3775 * Created win32/ directory which now includes MSVC++ specific
3776 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3777 It will appear only in the toolkit distribution
3779 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3781 * Changed the key material distribution function in case when
3782 the hash output is too short. The data is now concatenated
3783 a bit differently than it used to. Made the change to the
3784 SKE protocol specification.
3786 * Added better GMP detection to configure.in.pre. A patch
3789 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3791 * Fixed a minor bug in SKE that might cause some problem on
3792 some platforms. Affected file lib/silcske/silcske.c.
3794 * Added the cookie checking for initiator in the SKE. It checks
3795 that the responder returns the sent cookie unmodified. The
3796 affected file is lib/silcske/silcske.c. Added new SKE
3797 error type INVALID_COOKIE that can be sent during the
3798 negotiation. Fixed some memory leaks as well.
3800 * Added the "invalid cookie" error message to Irssi SILC client's
3803 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3805 * Added `task_max' field to the SilcClientParams to indicate
3806 the maximum tasks the scheduler can handle. If set to zero,
3807 default values are used. Affected file lib/silcclient/silcapi.h.
3809 * Fixed memory leaks in silc_client_close_connection. Affected
3810 file lib/silcclient/client.c.
3812 * Added silc_client_del_client_entry to client library to free
3813 all memory of given client entry. Affected file is
3814 lib/silcclient/idlist.[ch].
3816 * Added new functions silc_client_del_channel and
3817 silc_client_del_server to delete channel and server entries.
3818 Affected file lib/silcclient/[silcapi.h/idlist.c].
3820 * Removed silc_client_del_client_by_id from silcapi.h.
3822 * Fixed the INFO command to return the server's own info
3823 correctly when querying by Server ID. Affected file is
3826 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3828 * Removed the non-blocking settings in WIN32 code in the
3829 silc_sock_[read/write] and added SleepEx instead. Affected
3830 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3831 of input data is now checked with FIONREAD and ioctlsocket.
3833 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3835 * Call silc_schedule_task_del_by_context in the
3836 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3837 Affected file lib/silccore/silcprotocol.c.
3839 * Call silc_protocol_cancel for active protocols in the
3840 silc_server_close_connection if the funtion
3841 silc_server_free_sock_user_data has not been called.
3842 Affected file silcd/server.c.
3844 * Generic tasks cannot be deleted using the del_by_fd
3845 task deleting function since generic tasks does not match
3846 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3848 * Added a notion to SILCOPER help file that the SILCOPER works
3849 only on router server, not on normal server.
3851 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3853 * Added for WIN32 support for the new scheduler as well.
3854 Affected file lib/silcutil/win32/silcwin32schedule.c.
3856 * Fixed the SHA1 implementation to work on various platforms.
3858 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3860 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3861 API. It is part of the scheduler now. Everything else is
3862 as previously but some functions has changed their names.
3863 Checkout the lib/silcutil/silcschedule.h for the interface.
3864 Updated all applications to use the new interface. Affected
3865 files are lib/silcutil/silcschedule.[ch].
3867 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3869 * Found a bug in the SKE implementation. The HASH value,
3870 specified by the protocol, was not computed correctly. The
3871 public key of the responder was not added to the computation
3872 even though it is mandatory. Affected file lib/silcske/silcske.c.
3873 This unfortunately causes incompatibilities with older
3874 clients and servers.
3876 * Added WIN32 specific network init and uninit functions:
3877 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3878 the Winsock2. Affected file lib/silcutil/silcnet.h and
3879 lib/silcutil/win32/silcwin32net.c.
3881 * Set the socket always to nonblocking mode on WIN32 after
3882 reading data or writing data. Affected file is
3883 lib/silcutil/win32/silcwin32sockconn.c.
3885 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3887 * Fixed various compilation problems under WIN32. Affected
3888 files lib/silcutil/win32/silcwin32thread.c and
3889 lib/silcutil/win32/silcwin32schedule.c.
3891 * Removed all _internal.h #includes from public header
3892 files. Internal headers must never be included from
3895 Removed also the lib/silcske/payload_internal.h file.
3897 * All include files that may be needed (public and some others
3898 included by the public headers) by application developers are
3899 now copied to the ./includes directory. It does not copy any
3900 internal headers. Affected file Makefile.defines.pre and all
3901 Makefile.am's under lib/ and subdirs.
3903 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3905 * Do not change the ~/.silc directory's permissions automatically.
3906 Affected file irssi/src/silc/core/clientutil.c.
3908 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3910 * Do not cancel the protocol in silc_server_close_connection
3911 it might cause recursion. Now cancelled in the function
3912 silc_server_free_sock_user_data. Affected file silcd/server.c.
3914 * Fixed the silc_server_remove_clients_by_server to regenerate
3915 the channel keys correctly finally. Added also new function
3916 silc_server_remove_clients_channels to actually do it.
3917 Affected file silcd/server.c.
3919 * Fixed the silc_server_new_channel to not crash by giving
3920 wrong router to the new channel. Affected file is
3921 silcd/packet_receive.c.
3923 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3925 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3926 which is given as argument to the silc_client_alloc now.
3927 It can be used to configure the client and set various parameters
3928 that affect the function of the client.
3930 * The USERS command in server did not check whether the channel
3931 is private or secret. Affected file silcd/command.c.
3933 * Added new argument to the USERS command in protocol specification.
3934 The USERS command now can take the channel name as argument
3935 as well. Added support for this in client and server and
3936 updated the protocol specs.
3938 * Completed the GETKEY command in client. It can be now used
3939 to fetch also servers public key not only some clients.
3940 Affected files lib/silcclient/command[_reply].c.
3942 * Added silc_client_get_server to return server entry by the
3943 server name. Affected files lib/silcclient/silcapi.h and
3946 * Redefined the IDENTIFY command in protocol specification to be
3947 more generic. It now can be used to query information about
3948 any entity in the SILC Network, including clients, servers and
3949 channels. The query may be based either the entity's name
3950 or the ID. Added support for this in both client and server.
3952 Affected files silcd/command.c and lib/silcclient/command.c
3953 and command_reply.c.
3955 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3956 the _from_client and _from_server functions. Affected file
3959 * Added silc_client_get_channel_by_id_resolve to the file
3960 lib/silcclient/silcapi.h to resolve channel information by
3961 its ID. Added also silc_client_get_channel_by_id that
3962 does not resolve it from the server.
3964 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3966 * Added SilcServerEntry context into the client library
3967 to represent one server. The INFO command now allocates
3968 these to save the resolved server info. For now on the
3969 client library will also keep information about servers,
3970 connected and resolved with INFO.
3972 The INFO command now allocates the SilcServerEntry context
3973 and saves the server info there. The COMMAND_REPLY in
3974 the INFO now returns the parameters to application in
3975 same order as defined in the protocol specification.
3977 The entries are cached in the client->server_cache.
3979 * The INFO command is now issued after received the Client ID
3980 from the server. Affected file lib/silcclient/client.c.
3982 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3983 to the application as the mode changer might be server.
3984 It is guaranteed that NULL is not returned anymore to the
3985 application. Affected file lib/silcclient/client_notify.c.
3987 The ID Type is now also passed to the application so that
3988 it can check whether the returned entry is SilcClientEntry
3991 Added new function silc_client_get_server_by_id to return
3992 the server entry by ID. Affected files are the
3993 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3995 * Do not create the channel in the Irssi SILC Client when issuing
3996 the JOIN command but when received the sucessful JOIN command
3997 reply. Otherwise the channel might get created even though we
3998 could not join it. The Affected file is
3999 irssi/src/silc/core/[silc-channels.c/client_ops.c].
4001 * Fixed a channel joining bug in router. The router must also
4002 check the channel modes, invite and ban lists etc. when serving
4003 the JOIN command sent by normal server. Affected file is
4004 silcd/command.c. The router now resolves the client's
4005 information from the server who sent the JOIN command if it
4006 does not know it, and processes the JOIN command only after
4009 * Changed the SilcCommandCb to take new argument; void *context2.
4010 Affected file lib/silccore/silccommand.h
4012 The second argument in the command callbacks in the server now
4013 includes the SilcServerCommandReplyContext if the command was
4014 called as pending command callback from the command reply.
4015 Otherwise it is NULL. When called as pending the status of the
4016 command reply will be checked and if it was erronous the
4017 error will be sent to the original sender of the command.
4018 This way the client always receives the error messages even
4019 though the server was actually the one who received the error
4020 when it resent the command to router, for example. Affected
4021 files silcd/command[_reply].[ch].
4023 * Fixed sending WHOWAS command's error message to client if
4024 the requested client could not be found. It was missing.
4027 * Changed the CMODE and CUMODE commands reply arguments in the
4028 protocol specification. The Channel ID is now sent in both
4029 of the commands to identify the channel. Implemented this
4030 new feature to the client and server. Affected files
4031 lib/silcclient/command_reply.c and silcd/command.c.
4033 * Made better checks for invite and ban lists in the JOIN
4034 command in server. Affected file silcd/command.c.
4036 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4038 * The server now performs the incoming host IP/DNS lookup
4039 using the silc_socket_host_lookup and thus does not block
4040 the server anymore. Affected file silcd/server.c.
4042 * Completed the multi-thread support for SILC Scheduler in
4043 the lib/silcutil/silcschedule.c.
4045 * Fixed the configure.in.pre to detect the pthread correctly
4048 * Fixed a deadlock in silc_task_queue_wakeup in the file
4049 lib/silcutil/silctask.c.
4051 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4053 * Added new function silc_schedule_wakeup that is used in
4054 multi-threaded environment to wakeup the main thread's
4055 schduler. It needs to be used when a thread adds a new task
4056 or removes a task from task queues. After waking up, the
4057 scheduler will detect the task queue changes. If threads
4058 support is not compiled in this function has no effect.
4059 Implemented the wakeup mechanism to both Unix and WIN32
4060 systems. Affected files are lib/silcutil/silcschedule.[ch],
4061 lib/silcutil/unix/silcunixschedule.c and the
4062 lib/silcutil/win32/silcwin32schedule.c.
4064 * Added new function silc_task_queue_wakeup to wakeup the
4065 scheduler by the specified task queue. Affected file
4066 lib/silcutil/silctask.[ch].
4068 * The silc_socket_host_lookup_start now wakes up the scheduler
4069 after adding the timeout task. Affected file is
4070 lib/silcutil/silcsockconn.c.
4072 * The silc_socket_host_lookup is synchronous now if the threads
4073 support is not compiled in. However, the callback is still
4074 called asyncronously through the scheduler, anyway. Affected
4075 file lib/silcutil/silcsockconn.c.
4077 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4079 * Added new function silc_socket_host_lookup to perform
4080 asynchronous IP and FQDN lookups for the socket connection.
4081 Affected files lib/silcutil/silcsockconn.[ch].
4083 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4085 * Added SILC_MUTEX_DEFINE to define the mutex on environments
4086 that may or may not compile the mutex support in.
4088 Changed the silc_mutex_alloc interface. It allocates the
4089 mutex now to the sent pointer and returns TRUE or FALSE.
4091 Affected file lib/silcutil/silcmutex.h.
4093 * Wrote the SILC Task Queue interface to support multi-threads.
4094 Affected file lib/silcutil/silctask.[ch].
4096 * Wrote the SILC Scheduler to support multi-threads. Affected
4097 file lib/silcutil/silcschedule.c.
4099 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4101 * Implemented the SILC Mutex API and SILC Thread API for WIN32
4102 in lib/silcutil/win32/.
4104 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4106 * Defined SILC Mutex API and SILC Thread API and implemented
4107 them for Unix. Affected files are
4108 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
4109 lib/silcutil/unix/silcunixmutex.c and
4110 lib/silcutil/unix/silcunixthread.c.
4112 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4114 * Fixed the silc_server_remove_clients_by_server's channel
4115 key re-generation. The hash table handling was incorrect
4116 and would not work with many channels. Affected file is
4119 * Fixed some memory leaks around the server code.
4121 * Rewrote the silc_server_get_users_on_channel to support IPv6
4122 based Client ID's. Affected file silcd/server.c.
4124 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
4125 specification. However, a separate document must be written
4126 to define the detailed signing procedure and the payload
4127 associated with the flag. Defined the flag to the
4128 lib/silccore/silcchannel.h as well.
4130 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4132 * Changed the dynamic tables to static size tables in the
4133 lib/silccrypt/silchmac.c.
4135 * Removed GCC dependencies from the code. A patch by cras.
4137 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4139 * Do not show the error "Error receiving packet bla bla"
4140 in server if it really was not an error (-2 means that reading
4141 is pending). Affected file silcd/server.c.
4143 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4145 * Fixed a possible crash in silc_server_remove_clients_by_server
4146 in silcd/server.c. Fixed there also some memory leaks.
4148 * Fixed the silc_idlist_replace_client_id. It could replace
4149 wrong key in the hash table. Affected file silcd/idlist.c.
4151 * Do not check whether there are global users on the channel
4152 if the channel->global_users is FALSE. Affected functions
4153 silc_server_remove_from_one_channel and
4154 silc_server_remove_from_channels in silcd/server.c. Also,
4155 do not check if the removed client is local as we can be
4156 sure that global client was not removed from the channel
4157 and checking for global users is not needed.
4159 * The silc_server_remove_clients_by_server now re-generates
4160 the channel keys correctly for those channels that had
4161 clients removed from them. Affected file silcd/server.c.
4163 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4165 * Found the reason of random crashes in the server. We weren't
4166 ignoring the SIGPIPE signal (which can be sent in write())
4167 and it crashed the server. Affected file silcd/silcd.c.
4169 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4171 * Assure that sock->user_data is not NULL in the function
4172 silc_server_packet_send in silcd/packet_send.c.
4174 * Disconnect the remote connection if it could not be added
4175 to any ID lists in the server. The affected file is
4178 * Check in silc_server_packet_send[_real/dest] that the
4179 socket is not disconnecting and ignore the data if it is.
4180 Affected file silcd/packet_send.c.
4182 * Define inline to __inline on native WIN32 compilation.
4183 Affected file includes/silcwin32.h.
4185 * Added some explicit type casts for inline code since MSVC
4186 require them. Affected files lib/silcutil/silcbuffer.h,
4187 lib/trq/silcdlist.h and lib/trq/silclist.h.
4189 * Print warning in log files from now on if the packet
4190 decryption fails. Affected file silcd/server.c.
4192 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4194 * Changed the `say' client operation's interface to accept
4195 new `type' argument to indicate the type of the message sent
4196 by the library. The application may filter the library's
4197 messages according the type. The affected file is the
4198 lib/silcclient/silcapi.h.
4200 * Added two new functions to lib/silcclient/silcapi.h:
4201 silc_client_del_client and silc_client_del_client_by_id.
4202 Affected file lib/silcclient/idlist.c.
4204 * Moved the clientincludes.h from includes/ to silc/ and
4205 serverincludes.h from includes/ to silcd/.
4207 * The modes for the CMODE and CUMODE are now passed as
4208 uint32 for application with COMMAND_REPLY. The affected
4209 file is lib/silcclient/command_reply.c.
4211 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4213 * /WHOIS without arguments shows client's own information.
4214 Affected file lib/silcclient/command.c.
4216 * Changed PING to not accept any arguments. The specs
4217 says that client can ping only the connected server so
4218 requiring an argument is not needed. Affected file is
4219 lib/silcclient/command.c.
4221 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4223 * Fixed a fatal bug in private message sending and reception
4224 encryption and decryption when using private message keys.
4225 The implementation was incorrect and did not follow the
4226 specification. It causd that some of the message were
4227 lost since it did not use the sending and receiving keys
4228 as the protocol suggests. This has been fixed and will cause
4229 incompatibilities with older clients when sending private
4230 message encrypted with private message keys. Affected files
4231 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
4232 and various other in Irssi SILC Client.
4234 Added `responder' boolean argument to the functions
4235 silc_client_add_private_message_key[_ske] to indicate when
4236 the key is added as responder or initiator of the key
4239 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4241 * Removed the silc_ske_check_version function and created
4242 a SilcSKECheckVersion callback. Added also a function
4243 silc_ske_set_callbacks that is now used to set all SKE
4244 callbacks. The callback functions are not given to
4245 the SKE functions anymore, but this function is used to
4248 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
4250 * Added `silc_version' argument to the silc_client_alloc
4251 to define the version of the application for the library.
4252 The library will use the version string to compare it
4253 against the remote host's (usually a server) version
4254 string. Affected file lib/silcclient/silcapi.h
4256 * Added the KE protocol context to Key Agreement context
4257 in client library so that we can abort the SKE if it
4258 is in process when we get timeout. Affected file is
4259 lib/silcclient/client_keyagr.c.
4261 * Do not resolve the client ID forever if it returns in the
4262 first time that such client does not exist. This was done
4263 for example with private message. Affected file is
4264 lib/silcclient/client_prvmsg.c.
4266 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4268 * Do not add regex.h for WIN32. The affected file
4269 includes/silcincludes.h.
4271 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
4272 not work yet 100%. It generates the DLL's automatically
4273 when compiling with --with-win32 under cygwin.
4275 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4277 * lib/contrib/regex.c is not compiled on WIN32.
4279 * Added silc_net_get_socket_opt function to the
4280 lib/silcutil/silcnet.h.
4282 * Added includes/silcwin32.h for WIN32 specific includes
4285 * Do not use ptime structure or any of the posix process
4286 functions on WIN32 in lib/silccrypt/silrng.c.
4288 * Added silc_gettimeofday to provide generic function
4289 for struct timeval on all platforms. Added the function
4290 to lib/silcutil/silcutil.h.
4292 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4294 * Moved the lib/silccore/silcsockconn.[ch] to the utility
4295 library as they clearly belong there. As a plus side we
4296 can make the actual socket connection routines platform
4299 Added also new generic function silc_socket_read and
4300 silc_socket_write (that used to be silc_packet_[read/write].
4301 The implementation of these are platform specific.
4303 * Added WIN32 specific routines of silc_socket_[read/write]
4304 to lib/silcutil/win32/silcwin32sockconn.c.
4306 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4308 * Added preliminary support for native WIN32 compilation under
4309 cygwin (using the -mno-cygwin option for GCC) to the
4310 ./configure.in.pre. The --with-win32 now prepares the
4311 compilation for native WIN32.
4313 * Rewrote the SILC Scheduler interface in the file
4314 lib/silcutil/silcschedule.h. The scheduler is now context
4315 based and does not have anymore any global static scheduler.
4316 Moved the Unix scheduler to the lib/silcutil/unix/ directory
4317 and created lib/silcutil/win32 directory for WIN32 based
4320 * Added Unix specific network routines to the
4321 lib/silcutil/unix/silcunixnet.c and the old
4322 lib/silcutil/silcnet.c includes now only generic routines.
4324 Added WIN32 specific network routines to the
4325 lib/silcutil/win32/silcwin32net.c.
4327 * Added Unix specific utility functions from the
4328 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
4330 * Added WIN32 SILC Scheduler to the file
4331 lib/silcutil/win32/silcwin32schedule.c. The code is of course
4334 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4336 * Do not handle JOIN notify in the server if the target client
4337 is not registered (idata->registered == FALSE). The affected
4338 file is silcd/packet_receive.c.
4340 * Update the nickrec->founder in event_cumode in the Irssi SILC
4341 client. Affected file irssi/src/silc/core/silc-channels.c.
4343 * Fixed the CUMODE_CHANGE notify handling in the server when
4344 server and router are announcing their clients on channels.
4345 Now the mode changes are saved and notified correctly. The
4346 affected file is /silcd/packet_receive.c.
4348 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
4349 They really did not replace the cache entry in the ID Cache.
4350 Now they do that. Affected file silcd/idlist.c.
4352 * Fixed the KICK notify handling in the Irssi SILC client to
4353 update the channel records so that the kicked client does not
4354 appear to be on the channel. The affected file is
4355 irssi/src/silc/core/silc-channels.c.
4357 * Always update the conn->current_channel when executing command
4358 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
4360 * Fixed the KILL notify handling in Irssi SILC client to remove
4361 the killed client on all channels.
4363 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4365 * Fixed the silc_parse_command_line to remove extra spaces
4366 from the start and end of the arguments. Affected file is
4367 lib/silcutil/silcutil.c.
4369 * Cancel and free any active protocol in the function
4370 silc_server_close_connection. Affected file silcd/server.c.
4372 * Cancel and free any active protocol in the function
4373 silc_client_close_connction. Affected file is
4374 lib/silcclient/client.c.
4376 * Do not execute the KILL command for clients that are in
4377 history (ie. they are not in the network). Affected file is
4380 * Fixed KILL notify handling, client does not crash anymore.
4381 Affected file irssi/src/silc/core/silc-channels.c.
4383 * Reduced the default packet buffer size from 2048 to 1024 in
4384 lib/silccore/silcpacket.c.
4386 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
4387 counter to the SKE context that is incresed when the SKE library
4388 performs async operation outside the library. If the outside
4389 process frees the SKE context and FREED status will be set
4390 and the library will detect after the sync operation that the
4391 libary is freed. The affected files are
4392 lib/silcske/silcske[_status].[ch].
4394 * Resolve the client entry information in the function
4395 silc_client_channel_message to assure that NULL pointer is not
4396 passed as client entry to the application. */
4398 * Fixed the task timeout calculation to assure that there is
4399 never negative timeouts. The affected file is
4400 lib/silcutil/silcschedule.c.
4402 * Fixed the channel user mode notification sending in server.
4403 It was sent point-to-point to the router (or to server by router)
4404 but it needs to be destined to a channel. The routines now
4405 supports sending the channel user mode notifys to the channels
4406 when announcing clients and channels. Affected files are
4407 silcd/server.c and silcd/packet_receive.c.
4409 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
4410 It did not actually replace the old channel entry in the cache.
4411 Affected file lib/silcclient/client_notify.c.
4413 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4415 * Fixed a possible crash in silc_packet_send_prepare. It now
4416 assures always that there is enough space in the buffer and
4417 at the tail area of the buffer (for MAC).
4419 Fixed the inbound buffer reallocation in silc_packet_read.
4420 It was old code and did not handle the reallocation correctly.
4423 The affected file is lib/silccore/silcpacket.c.
4425 * Fixed buffer overflow in silc_parse_nickname in the file
4426 lib/silcutil/silcutil.c.
4428 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4430 * make install generates new server keys only if there is not
4433 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4435 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
4436 Added check that if the NOREPLY is set then we will not send
4437 the away message. This avoids infinite loop of away messages
4438 if both clients are away. The affected file is
4439 lib/silcclient/client_prvmsg.c.
4441 * Fixed client crash if /NICK was given without arguments.
4442 Affected file lib/silcclient/command.c.
4444 * Server does not send the invite list in INVITE command back
4445 to the client if the list was not altered. Added this notion
4446 to the protocol spec as well. Affected file silcd/command.c.
4448 Fixed possible crash in INVITE command by checking the
4449 value of silc_server_get_client_route command.
4451 * Fixed the INVITE notify type handling. The arguments are now
4452 taken in correct order and client does not crash. The affected
4453 file is irssi/src/silc/core/silc-channels.c.
4455 Removed the "Inviting xxx to channel" message from the
4456 client library away and let the application handle it.
4457 Affected file lib/silcclient/command.c. Added that message
4458 to Irssi SILC client's message formats.
4460 * Fixed CMODE command crash in client. It now checks the
4461 amount of arguments correctly and does not crash. The affected
4462 file is lib/silcclient/command.c.
4464 * Do not create new channel automatically in silc_channels_join
4465 but check whether the channel by that name already exists.
4466 Affected file irssi/silc/core/silc-channels.c.
4468 * Do not send the SERVER_SIGNOFF to router if the disconnected
4469 entity was the router. Affected file silcd/server.c.
4471 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
4472 SILC client as it was missing from there.
4474 Added the handling of the KICK notify to the Irssi SILC client
4475 as it was missing. Added "you have been kicked" message to
4476 Irssi SILC client's message modules formats.
4478 Added the handing of the KILL notify to the Irssi SILC client
4479 as it was missing. Added the kill message module formats
4482 The affected file is irssi/src/silc/core/silc-channels.c.
4484 * The router did not save the channel mode the server announced.
4485 Affected file silcd/packet_receive.c.
4487 * Fixed a possible crash in INFO command in server. If the
4488 server did not provide the server info it crashed. Affected
4489 file silcd/command.c.
4491 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4493 * Fixed the GETKEY command in the server to check also the
4494 global list. Otherwise the GETKEY would not work correctly
4495 in normal SILC server. Affected file silcd/command.c.
4497 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4499 * Fixed GETKEY crash, it crashed if the command did not succseed.
4501 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4503 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
4504 is now real and not just an macro interface to GMP.
4506 Removed the entire GMP from the source tree and imported new
4507 NSS MPI library instead. Reason for removing GMP is that it is
4508 extremely large and compiles extremely slow. The NSS MPI
4509 is only a few files and compiles in less than 10 seconds.
4510 The speed is also about the same as GMP. The MPI is imported
4511 to lib/silcmath/mpi.
4513 If the system has GMP installed we will still use the GMP.
4514 If it is not then the NSS MPI will be compiled.
4516 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4518 * Merged a long nickname (127 characters long) crash bugfix from
4519 Irssi CVS tree. Affected file irssi/src/core/misc.c.
4521 * Merged a freed memory reference bugfix from Irssi CVS tree.
4522 Affected file irssi/src/core/commands.c.
4524 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4526 * Added the server's public key sving and verification to the
4527 server when performing the SKE. This was missing and the
4528 remote server's (or router's) public key was accepted without
4529 checking whether we have it previously or trust it at all.
4530 Affected file silcd/protocol.c.
4532 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4534 * Check in the silc_server_timeout_remote if protocol is active
4535 and make sure that the protocol's final callback is called so
4536 that all memory if freed. Affected file silcd/server.c.
4538 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4540 * silc_server_whois_send_reply crashed the server if the nickname
4541 was 127 characters long. Affected file silcd/command.c.
4543 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4545 * Added sanity check to the silc_server_new_client. If the hostname
4546 is provided inside username then check that the provided hostname
4547 really is the same as the resolved one. If the hostname was not
4548 resolved then check it from the public key. Affected file is
4549 silcd/packet_receive.c.
4551 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
4552 if the server disconnected us and the connection is not valid
4553 anymore. Affected file irssi/src/silc/core/silc-channels.c.
4555 * Moved the silc_client_[chmode|chumode|chumode_char] away from
4556 the library to the lib/silcutil/silcutil.[ch].
4558 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4560 * Close log file after open. Affected file
4561 lib/silcutil/silclog.c.
4563 * Check whether sock == NULL in silc_client_send_packet and return
4564 if it is. Affected file lib/silcclient/silcclient.c.
4566 * Check rec->entry == NULL in the Irssi SILC Client before
4567 sending the channel message. Affecte file is
4568 irssi/src/silc/core/silc-servers.c.
4570 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4572 * Merged a splitted window bugfix from Irssi CVS tree. The
4573 affected file is irssi/src/fe-text/textbuffer-view.c.
4575 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
4576 It did not print nickname.
4578 * Improved the distributions system a bit.
4580 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4582 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
4583 irssi/src/fe-text/gui-window.c.
4585 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
4586 to in-active server. The affected file is
4587 irssi/src/silc/core/client_ops.c.
4589 * Resolve the client in USERS command reply if the entry does
4590 not have username resolved. The affected file is
4591 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
4592 command to WHOIS command to really resolve stuff. The USERS
4593 is not used any more in any critical section so WHOIS can
4594 be used even though it might be slower than IDENTIFY.
4596 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
4599 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4601 * Changed the protocol API a bit more consistent in the
4602 lib/silccore/silcprotocol.[ch].
4604 * Changed the following headers to ROBODoc format:
4606 lib/silccore/silcpayload.h
4607 lib/silccore/silcprotocol.h
4608 lib/silccore/silcsockconn.h
4610 All core library headers are now formatted.
4612 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4614 * Fixed a bug in Irssi SILC client; do not show that you are
4615 server/router operator if you really are not. Affected file is
4616 irssi/src/silc/core/client_ops.c.
4618 * Renamed silc_command_free_payload to silc_command_payload_free.
4619 Affected file lib/silccore/silccommand.h
4621 * Added silcmath.h to include the prototoypes of various routines
4622 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
4625 * Changed the following headers to ROBODoc format:
4627 lib/silccore/silcchannel.h
4628 lib/silccore/silccommand.h
4629 lib/silccore/silcid.h
4630 lib/silccore/silcidcache.h
4631 lib/silccore/silcmode.h
4632 lib/silccore/silcnotify.h
4633 lib/silccore/silcpacket.h
4634 lib/silcmath/silcmath.h
4636 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4638 * Added checking to the server code not to start the server if
4639 ciphers and stuff are not configured properly. Affected files
4640 silcd/serverconfig.[h] and silcd/server.c.
4642 * Changed the layout of the header files of the public interfaces
4643 in the SILC libraries. The new layout supports ROBODoc
4644 documentation tool (and some others) so that it is easy to create
4645 a library reference manual. All the other headers and source
4646 code must still follow the CodingStyle document. Also source
4647 code must not include these ROBODoc stuffs, only the headers.
4648 Furthermore, all public interface headers must now be named
4649 by using `silc' prefix, example: silcapi.h, silccipher.h.
4650 Some files were renamed due to this. All the other headers
4651 must not be used as public interfaces. I will update the
4652 CodingStyle document later. Changed following headers, so far:
4654 lib/silcclient/silcapi.h
4655 lib/silccore/silcauth.h
4656 lib/silccore/silcprivate.h
4657 lib/silccrypt/silcdh.h
4659 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4663 * Removed silc_client_packet_send_flush from the client library
4664 as it is not needed. Affected file lib/silcclient/client.[ch].
4666 * Added printing of message of unresolved authentication method
4667 to the Irssi SILC client. Added it to the module formats.
4668 Removed the same message from the client library.
4670 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4672 * Added new distribution feature, DISTLABEL. Every distribution
4673 can define own preprocessor label that can be used in the
4674 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
4675 file distributions, acconfig.h.pre and prepare.
4677 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4679 * Added Makefile.defines_int to include the actual definitions
4680 for Makefile.defines.in. Tested the new distribution system,
4681 created distributions and tested installation.
4683 * Added AWAY message printing to the Irssi SILC client. Added
4684 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
4686 * Added SCONNECT command to call the SILC's CONNECT command.
4687 Cannot use CONNECT directly since Irssi uses that internally.
4688 Affected file irssi/src/silc/core/silc-servers.c.
4690 Added ACTION local command. It is same as ME command but takes
4691 the channel as mandatory argument.
4693 Rewrote some of the Irssi's help files to suite for SILC
4696 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4698 * Added Makefile.defines[.in] that should for now on be included
4699 in all Makefile.am file in the source tree. That file includes
4700 all common compilation definitions for SILC source tree.
4702 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4704 * Minor changes to the ./prepare script to change the package
4705 name according the distribution name to the configure.in.
4707 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4709 * Created new distribution system. Added file `distributions'
4710 that defines all the distributions that can be created out of
4711 the SILC source tree. The ./prepare script now reads that
4712 file to determine how to prepare the distributions. The
4713 first argument to the ./prepare is the name of the distribution
4714 and second is the version of the distribution. If given
4715 without arguments it creates the default (toolkit) distribution
4716 with the default version (defined in ./prepare).
4718 All Makefile.am files that are subject to the distributions
4719 are now named as Makefile.am.pre. These are ./Makefile.am
4720 and lib/Makefile.am. Others may be changed later.
4722 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4724 * Added invite list, ban list, some key management and connection
4725 error message printing to module formats in the Irssi SILC client.
4727 * Added new silc_client_set_away_message to set the away message
4728 that is back to the person who sent private message. The
4729 affected file lib/silcclient/silcapi.h and the
4730 lib/silcclient/client_prvmsg.c.
4732 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4734 * Fixed the private message sending in the Irssi SILC client,
4735 added local command KEY to the Irssi SILC client.
4737 Added key management and key agreement message formats to the
4738 irssi/src/fe-common/silc/module-formats.[ch].
4740 Added USERS (alias WHO) printing, server/router operator
4741 indication and LIST command printing to the module formats.
4743 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4745 * Fixed channel joining notify handling, cumode notify handling
4746 from Irssi SILC client.
4748 * Added SILC specific module-formats to the Irssi SILC client so
4749 that SILC specific message hilighting, colors etc is possible.
4750 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4752 Added channel mode, channel user mode, actions, notices,
4753 whois and whowas printing to the the module-formats.c.
4755 * Fixed a bug in channel deletion in the server. The channel
4756 is not left to the cache even if the channel founder auth mode
4757 is set when there are no users anymore on the channel. Affected
4758 file silcd/server.c.
4760 * The silc_net_localhost now resolves the entire hostname including
4761 the domain name. Affected file lib/silcutil/silcnet.c.
4763 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4765 * Changed the ask_passphrase client operation to be ascynchronous.
4766 It has now a completion callback and a context that the
4767 application must call after it has got the passphrase from
4768 the user. Affected files lib/silcclient/silcapi.h,
4769 lib/silcclient/protocol.c, lib/silcclient/command.c and
4772 Added SilcAskPassphrase callback that the application calls
4773 to deliver the passphrase to the library.
4775 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4776 The public key verification and especially a certificate
4777 verification is asynchronous procedure.
4779 Added new SILC_SKE_STATUS_PENDING status to indicate the
4780 request is pending and a callback will be called to finalize
4783 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4784 indicate that remote end did not send its public key (or
4785 certificate), even though we require it. Added check for this
4786 condition in the SKE. This was a security bug, now fixed.
4788 Defined new SilcSKEVerifyCbCompletion callback that is called
4789 when the verification process is completed.
4791 The affected files lib/silcske/silcske_status.h and
4792 lib/silcske/silcske.[ch].
4794 * Changed the verify_public_key client operation to be async
4795 as well. Defined SilcVerifyPublicKey callback that is used to
4796 indicate the success of the public key verification process.
4798 Changed the server and client to use the new async client
4801 * Changed the Irssi SILC client's internal scheduler to be called
4802 twice as many times as it used to be. As a result the client
4803 should be a bit faster now. Affected file is
4804 irssi/src/silc/core/silc-core.c.
4806 * Added support to Irssi SILC client of asynchronous public key
4807 verification and passphrase inquiry. Affected file is
4808 irssi/src/silc/core/silc-core.c.
4810 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4812 * Do not say "You have left channel %s" in client library.
4813 Moved it to the application. Affected files are
4814 lib/silcclient/command.c and silc/client_ops.c.
4816 * Fixed silc_client_get_clients. Command context was not
4817 duplicated and was freed memory in the callback. Affected
4818 file lib/silcclient/idlist.c.
4820 * Do not say "you are now talking..." on JOIN command in the
4821 client library. The appliation must handle it.
4823 * Do not say ".. changed topic to" in command reply in the
4824 client libary. The application must handle it.
4826 * Fixed TOPIC command sending in the client library.
4828 * Fixed a memory leak in silc_client_command_free in the file
4829 lib/silcclient/command.c.
4831 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4833 * Imported a modified version of Irssi client to the source tree.
4834 The Irssi will be used to create a new client called
4835 Irssi SILC. Imported to irssi/.
4837 Added silc_core_init_finish function to the Irssi. Affected
4838 file irssi/configure.in.
4840 A lot changes in the Makefile.ams around the irssi tree.
4842 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4844 * Do not rehash if the new size is same as the old size of the
4845 hash table, in the silc_hash_table_rehash*. The affected file
4846 lib/silcutil/silchashtable.c.
4848 * Replaced hash_table_del_by_context calls from the server
4849 (when channel->user_list and client->channels) to the
4850 hash_table_del as it is sufficient and faster.
4852 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4854 * Added silc_hash_table_list, silc_hash_table_get and the
4855 SilcHashTableList structure to provide an alternative way to
4856 traverse the hash table. The affected files are
4857 lib/silcutil/silchashtable.[ch].
4859 * Changed the server's idlist routines to use the hash table
4860 routines to optimize the code.
4862 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4864 * Replaced the client entry's `channel' list and channel entry's
4865 `user_list' list to hash tables for optimized lookup. Changed
4866 the code to use the hash table interface around the code.
4867 Affected file lib/silcd/idlist.[ch].
4869 * Added `auto_rehash' boolean argument to the function
4870 silc_hash_table_alloc to indicate whether the hash table should
4871 auto-rehash when it thinks is appropriate time. It will
4872 increase the hash table size if the there is twice as much
4873 entries in the table than the size of the table, and will
4874 decrease the size if there are twice as less entries than
4875 the size of the table.
4877 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4879 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4881 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4883 * silc_idcache_purge_by_context deletes the entry now by context
4884 as it is supposed to do. Affected file lib/silccore/idcache.c.
4886 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4887 client is not anymore valid (WHOWAS givens the info) and not
4888 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4890 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4892 * Removed the `data' and `data_len' arguments from the ID Cache
4893 interfaces and added `name' argument. ID Cache does not handle
4894 anymore the binary data only a names associated with given ID.
4896 * When hashing a Client ID with silc_hash_id the entire ID is
4897 not hashed anymore, instead only the hash of the Client ID is
4898 hashed. This way we can access the Client ID from the cache
4899 with Client ID but with the hash of the ID (which is a hash of
4900 the nickname) as well without any difference in performance.
4902 Added also silc_idcache_find_by_id_one_ext to do one on one
4903 searching when we have the actual ID. Added also function
4904 silc_hash_client_id_compare. The affected files are
4905 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4907 * When hashing the name associated with a ID it is always done
4908 in lowercase. This way we can access the cache without worrying
4909 about case-sensitivity, even though, for example nicknames are
4912 * Fixed a bug in server with channel message sending. It put
4913 wrong ID type as destination ID. The affected file
4914 silcd/packet_send.c.
4916 * silc_idcache_del_by_context now deletes from all hash tables
4917 by context. Affected file lib/silccore/idcache.c.
4919 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4921 * Changed the client library to use the new ID Cache interface.
4922 Changes around the source tree.
4924 * Added silc_hash_table_rehash_ext to rehash with specific
4925 hash function. Affected file lib/silcutil/silchashtable.[ch].
4927 * Added silc_hash_string_compare to compare two strings in the
4928 hash table. Affected file lib/silcutil/silcutil.[ch].
4930 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4932 * Added new function silc_idcache_del_by_context into the
4933 lib/silccore/idcache.[ch].
4935 * Changed the server's ID list routines to use the new ID Cache
4936 interface. Changes around the source tree.
4938 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4940 * Added silc_hash_table_del[_by_context]_ext functions in to the
4941 lib/silcutil/silchashtable.[ch].
4943 Removed silc_hash_table_find_all* routines and added new
4944 silc_hash_table_find_foreach to replace them.
4946 Added silc_hash_table_replace_ext function as extended
4947 replacing function. Separated the simple hash table interface
4948 from the extended hash table interface in the file
4949 lib/silcutil/silchashtable.h.
4951 * Fixed minor bugs and changed it to use some of the new
4952 hash table functions in lib/silccore/idcache.c
4954 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4956 * Added new function silc_hash_table_find_all to return all keys
4957 in the hash table by the specified key. As the hash table is
4958 collision resistant it also makes it possible to have several
4959 duplicate keys in the hash table. This function may be used to
4960 find all of the keys from the hash.
4962 Added user_context arguments to the SilcHashFunction,
4963 SilcHashCompare and SilcHashDestructor to deliver user specified
4966 Added new fuctions silc_hash_table_find[_all]_ext to do
4967 extended lookup with specified hash and compare functions and
4968 specified user contexts.
4970 Added new function silc_hash_table_add_ext to add the key
4971 with specified hash function and user context.
4973 Added new function silc_hash_table_foreach to traverse all
4974 entrys in the hash table. Added SilcHashForeach callback
4977 Added new function silc_hash_table_del_by_context to delete
4978 the entry only if the context associated with the key matches.
4980 Affected files are lib/silcutil/silchashtable.[ch].
4982 * Removed silc_hash_[server/client/channel]_id and added just
4983 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4984 silc_hash_id_compare to compare two ID's using as the hash table
4985 comparison function. Added also silc_hash_data to hash
4986 binary data and silc_hash_data_compare to compare it.
4988 * Removed silc_idlist_find_client_by_hash as it is not needed
4989 anymore. Affected file silcd/idlist.[ch].
4991 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4992 to use internally the SilcHashTable. The new ID Cache is a lot
4993 faster than the old one. Some of the ID Cache interface was also
4994 rewritten and obsolete and stupid functions were removed.
4996 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4998 * Added entry_count field to the SilcHashTable to keep the number
4999 of the entries in the table. Implemented the function
5000 silc_hash_table_rehash. Added new function
5001 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
5003 Fixed a minor bug in silc_hash_table_free.
5005 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
5006 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
5007 into the lib/silcutil/silcutil.[ch].
5009 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5011 * Implemented a collision resistant hash table into the
5012 lib/silcutil/silchashtable[ch]. See the header and the source
5013 for the SilcHashTable API.
5015 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5017 * Merged dotconf version 1.0.2 into lib/dotconf.
5019 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5021 * Do not compile anything in lib/silcsim/* if the SIM support
5022 is not enabled. The tree should now compile without problems
5025 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5027 * Compiled the SILC under cygwin. Compiled and tested briefly
5028 without problems. More tests needed. The SIMs didn't compile
5031 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
5033 * Fixed possible crash in silc_get_username in the
5034 lib/silcutil/silcutil.c.
5036 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5038 * Fixed a va_arg in silc/client_ops.c.
5040 * Oops, RC5 routines were named AES and caused some problems
5041 when not using SIM's. Affected file lib/silccrypt/rc5.c.
5043 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5045 * Added new SilcIDIP structure into the lib/silccore/id.h and
5046 replaced the old `ip' fields from all SILC ID's to that type.
5047 This is a step towards IPv6 support.
5049 The silc_id_get_len takes now the ID as an extra argument.
5050 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
5051 both IPv4 and IPv6 based ID's.
5053 The affected files are lib/silccore/id.[ch] and other files
5054 around the tree using these routines.
5056 * Removed the ID length arguments in server from various
5057 silc_server_send_notify_* routines -> they are not needed
5060 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5062 * Fixed memory leak in silc_encode_pem_file in the file
5063 lib/silcutil/silcutil.c.
5065 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5067 * Check minor version as well in the SKE. Affected files are
5068 silcd/protocol.c and lib/silcclient/protocol.c.
5070 * Added --identifier option to the server so that an identifier
5071 can be when creating the public key for the server. Affected
5072 file is silcd/silcd.c.
5074 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
5075 lib/silccrypt/silcpkcs.c.
5077 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5079 * Register default ciphers and stuff when using -C option with
5080 the server. Affected file sildc/silcd.c.
5082 * Put back the servers public key filename format, it is better
5083 than the new one. For now, the client keys are saved with the
5084 new filename format. The affected file silc/client_ops.c.
5086 * Implemented the Cipher API for the rest of the ciphers that
5087 did not implement it or implemented it the wrong way.
5089 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5091 * Register default ciphers and stuff when using the -S option
5092 in the client. Affected file silc/silc.c. Same also when
5093 creating new key pair with -C option.
5095 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5097 * Fixed the silc_verify_public_key client operation function to
5098 save the public keys differently. The fingerprint is now
5099 used as filename and not the hostname. This way also the
5100 client keys are saved uniquely and not with hostnames. The
5101 affected file is silc/client_ops.c.
5103 * Trimmed the silc_hash_fingerprint function to remove extra
5104 whitespaces from the end of the fingerprint. The affected
5105 file is lib/silccrypt/silchash.c.
5109 * Added silc_cipher_register_default function to register all
5110 default ciphers. It can be used when configuration files
5111 does not exist and the application does not want any specific
5112 ciphers in any specific order.
5114 The SilcDList is now used as silc_cipher_list dynamically
5115 allocated cipher list. Removed the static list all together
5116 and now all ciphers must be allocated to the dynamic list.
5117 The silc_cipher_alloc routine was changed to check only the
5120 All silc_cipher_* routines that used to return int returns
5123 The affected files lib/silccrypt/silccrypt.[ch].
5125 * The same thing was done to silc_hash_* as for silc_cipher_*
5126 routines. Affected files lib/silccrypt/silchash.[ch].
5128 * The same thing was done to silc_pkcs_* as for silc_cipher_*
5129 routines. Affected files lib/silccrypt/silcpkcs.[ch].
5130 Added also silc_pkcs_[un]register[_default] functions.
5131 Removed the data_context from the PKCS API.
5133 * Added silc_hmac_register_default function to register default
5134 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
5135 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
5136 to unregister all hmacs at once.
5138 * Register the default ciphers, hash functions, PKCSs and HMACs
5139 if client's configuration file does not exist. The affected
5142 * The client did not load the hash functions from the SIM
5143 modules at all. Added support for this. Affected file is
5144 silc/clientconfig.c.
5146 * When decoding public key with silc_pkcs_public_key_decode, check
5147 the supported algorithm only if PKCS are registered. Affected
5148 file lib/silccrypt/silcpkcs.c. The same was done with the
5149 silc_pkcs_private_key_decode.
5151 * Fixed the SILC List routines to keep the list always in order.
5152 It used to change the list's order when traversing the list but
5153 not it preserves the order. Affected file lib/trq/silclist.h.
5155 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5157 * Added the client library to use the SilcSocketConnection's
5158 reference counter (by silc_socket_dup) to prevent the bug that
5159 the socket object may be freed underneath async operation.
5161 * The name resolv library checking fixes in the configure.in.pre.
5164 * Created new version of the protocol drafts for future
5165 development. The -03 drafts are the ones that will be changed
5166 in the trunk now and the -02 will remain as they are.
5168 * Send list of CUMODE notifys to the router when announcing
5169 the channel users to the router. Affected file silcd/server.c.
5170 If the router receiving channel founder CUMODE for a channel
5171 that already has channel founder it will send CUMODE notify
5172 to the sender to remove the channel founder rights from the
5173 announced client. Affected file silcd/packet_receive.c.
5175 * The CUMODE notify may now use Server ID as well as the entity
5176 who changes the mode. Updated protocool specs.
5178 * Updated INSTALL and README files.
5180 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5182 * New web pages in the http://silc.pspt.fi. The pages was
5187 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5189 * Implemented the [DenyConnectin] config section in the server.
5190 Added silc_server_config_denied_conn to check whether incoming
5191 connection is denied. Affected file silcd/serverconfig.[ch].
5193 * Do not check the ports when checking the incoming configuration
5194 data if the port is 0, meaning any. Affected file is
5195 silcd/serverconfig.c.
5197 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5199 * Fixed buffer overflow in silc_string_compare in the file
5200 lib/silcutil/silcutil.c.
5202 * Fixed double free in silc_server_command_leave in the file
5205 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5207 * Fixed the version checking in the server. Affected file is
5210 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5212 * Fixed the configuration data fetching when accepting new
5213 connections in the server. Affected file silcd/server.c.
5215 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5217 * Added `sender_entry' argument to the function
5218 silc_server_packet_relay_to_channel so that we can check
5219 whether some destination actually belongs to the same route
5220 the sender belongs (ie, we must not resend the packet to the
5221 sender). Affected file silcd/packet_send.[ch].
5223 * Added `servername' field to the SilcClientEntry in the server
5224 to hold the name of the server where client is from. Affected
5225 file is silcd/idlist.h.
5227 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5229 * Moved the channel message encrypting in the router betwen
5230 router connections from silc_server_channel_message to the
5231 silc_server_packet_relay_to_channel since we want to check
5232 whether we have anybody channel before encrypting anything.
5233 Affected files silcd/packet_[receive/send].c.
5235 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5237 * Fixed the [AdminConnection] server config section to support
5238 multiple entries. Affected file silcd/serverconfig.c.
5240 * Added support into the server to check the validity of the
5241 incoming connection before executing any KE or authentication
5244 * The connection configuration is now saved to the KE and
5245 connection auth protocol contexts and not fetched anymore in
5246 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
5248 * The local hosts listenning address and port is also resolved
5249 now when starting the server. We want to have the socket object
5250 to include the real address and port for the listener. Added
5251 new function silc_net_check_local_by_sock into the files
5252 lib/silcutil/silcnet.[ch].
5254 * Fixed a broadcast bug in server -> do not broadcast if we
5257 * Fixed a routing bug. Do not route broadcast packets ever.
5258 Broadcast packets must be processed always and not routed since
5259 they may be destined to some other host than yourself and thus
5260 would get routed without no good reason. Affected file is
5263 * Added function silc_server_config_is_primary_route to check
5264 whether primary router connection has been configured (a router
5265 configuration that we are initiating). If there is not, we
5266 will assume that there is only two routers in the SILC network
5267 and we will use the incoming router connection as our primary
5268 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
5270 * Changed the order of the broadcasting. Broadcast _after_ the
5271 packet has been processed not before. Affected file is
5274 * Fixed a [ClientConnection] parsing bug. The port was never
5275 parsed correctly thus resulting to port 0. Affected file
5276 silcd/serverconfig.c.
5278 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
5279 argument and did not set the broadcast packet flag. Affected
5280 file silcd/packet_send.c. Fixed same bug in the function
5281 silc_server_send_notify as well.
5283 * If we receive NEW_ID packet for our own ID in the server, ignore
5286 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5290 * Removed the nickname from the Private Message Payload.
5291 Updated the code and the protocol specs.
5293 * Updated protocol specs for submitting to the IETF.
5295 * Tweaked the Random Number Generator a bit. Affected file
5296 lib/silccrypt/silcrng.c. Exported a new function
5297 silc_rng_[global]_add_noise which can be used to add more
5300 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5302 * Do not parse packets with different timeout when protocol
5303 is active -> may cause problem with rekey. Affected file
5306 * When server receives signoff notify it must not create
5307 new channel key if the client is on any channels since the
5308 sender of the signoff notify will create it.
5310 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5312 * Added printing of error messages during SKE protocol from the
5313 failure packet sent by server during SKE. Affected file
5316 * Removed the client's failure_callback handling with timeout
5317 and handle it immediately when received.
5319 * The SKE library returned wrong type in SUCCESS and FAILURE
5320 packets. They must be 32 bit MSB not 16 bit MSB.
5322 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5324 * Ok, rewrote the logic of the re-key and now it seems to work.
5325 I tested it on high traffic with frequent re-keys without
5326 problems. Added hmac_receive (and renamed hmac to hmac_send)
5327 in SilcClientConnection in lib/silcclient/client.h and
5328 in SilcIDListData in silcd/idlist.h. Also, removed the
5329 SilcPacketParserContext's cipher and hmac fields as they are
5330 not needed anymore and actually caused some problems when
5331 the ciphers and hmac's changed underneath the packet parser.
5333 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5335 * If re-key protocol is active then process the incoming packets
5336 synchronously since we must assure that icoming packets encrypted
5337 with the old key is processed before the new keys is set to
5338 use. This is true other packets than for REKEY packets.
5339 Affected file silcd/server.c. The same was done to client library
5340 as well, affected file lib/silcclient/client.c.
5342 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5344 * Fixed bug in client and server to accept the force send if
5345 the packet is send from silc_[server/client]_packet_process
5346 function. Otherwise the packets are never delivered, oops.
5348 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5350 * Disable force sending of packets when REKEY protocol is active.
5351 We must assure that no packet is sent directly when rekey is
5352 performed. All packets must be sent through packet queue.
5353 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
5354 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
5355 function is silc_[server/client]_packet_send_real to check
5358 * Replaced the SIM paths from example config files to
5359 /usr/local/modules. Also, make install creates now
5360 /usr/local/silc/logs directory to hold all the SILC server
5363 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5365 * Made the configure.in.pre work on Solaris. Patch by salo.
5367 * Made all ciphers compatible with non-x86 machines. Defined
5368 CBC mode macros into lib/silccrypt/ciphers_def.h.
5370 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5372 * Fixed the make install.
5374 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5376 * When MAC computation fails the silc_packet_decrypt returned 0
5377 even though it was supposed to return -1. Fixed this. The
5378 affected file is lib/silccore/silcpacket.c.
5380 * Do not replace the config files in /etc/silc (in make install)
5381 if they already exist. Affected file ./Makefile.am.
5383 * Do not send re-key packets immediately but through packet queue.
5384 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
5386 * Changed silc_net_check_host_by_sock to return FALSE if the
5387 IP/DNS could not be resolved. Though, it returns the IP address
5388 now even if it could not resolve it (but returns also FALSE).
5389 Affected file lib/silcutil/silcnet.[ch].
5391 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5393 * Added silc_pkcs_decode_identifier to decode the public key's
5394 identifier. Affected file lib/silccrypt/silpkcs.[ch].
5395 Added also silc_pkcs_free_identifier. Added also new context
5396 SilcPublicKeyIdentifier.
5398 * Added -S option to the silc client. It is used to dump the
5399 contents of the specified public key file.
5401 * Changed the PKCS api to return the public key length when
5402 setting the public key.
5404 * Fixed a fatal bug in the public and private key file loading.
5405 Affected file lib/silccrypt/silcpkcs.c.
5407 * Execute the packet parsing for client with zero (0) timeout
5408 if the protocol is active. Affected file silcd/server.c.
5410 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5412 * Made the key generation options to the silcd program. Added
5413 -C option, equivalent to client's option.
5415 * Added new [ServerKeys] config section to the server. It
5416 configures the server's public and private key.
5418 * Defined generic Public Key Payload into the protocol
5419 specification to send specific type of public keys and
5422 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
5423 public key or certificate.
5425 * Implemented the GETKEY command to the server and to the
5426 client library and on user interface.
5428 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5430 * Made preliminary `make install' work.
5432 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5434 * Added SilcServerRekey context into silcd/idlist.h.
5436 * Added the PFS support as defined in the specification to the
5437 SKE protocol. Affected files lib/silcske/*.c.
5439 * Added `ske_group' field to the SilcServerRekey context to hold
5440 the number of the SKE group that is used with PFS in re-key.
5441 Affected file silcd/idlist.h.
5443 * Added PFS re-key support to the server. Affected file is
5446 * Added silc_protocol_cancel to cancel execution of the next
5447 state of the protocol. Affected file is
5448 lib/silccore/silcprotocol.[ch].
5450 * Added the re-key support with and without PFS to the client
5451 library. Re-key is performed once in an hour, by default.
5453 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
5454 Added silc_client_rekey_callback and silc_client_rekey_final.
5455 Affected files are lib/silcclient/protocol.[ch] and
5456 lib/silcclient/client.[ch].
5458 * Removed the `hmac_key' and `hmac_key_len' fields from the
5459 SilcClientConnection structure; not needed. Affected file is
5460 lib/silcclient/client.h.
5464 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5466 * Do not ask whether user wants to use the negotiated private key
5467 for private messages, just use it. Affected file is
5468 silc/local_command.c.
5470 * Added `send_enc_key' and `enc_key_len' fields to the
5471 SilcIDListData structure since they are needed in the re-key
5472 phase. Affected file is silcd/idlist.[ch].
5474 * Implemented the simple re-key protocol into the server.
5475 Affected files silcd/server.c and silcd/protocol.[ch]. The
5476 re-key will be performed once in an hour, by default.
5478 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
5479 Added silc_server_rekey, silc_server_rekey_callback and
5480 silc_server_rekey_final.
5482 * Removed Tunneled flag from the protocol. Updated the code
5483 and the specifications.
5485 * Adde `pfs' field to the SilcIDListData to indicate whether
5486 the PFS is to be performed in the re-key. Affected file is
5489 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5491 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
5492 int64 of at least the xintXX size. If void * is less that 4
5493 bytes uint32 * will be used. Defined bool as boolean.
5495 * Changed _ALL_ unsigned long and unsigned int to uint32,
5496 unsgined short to uint16 in the source tree.
5498 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
5499 not handle clients that has entry->data.registered == FALSE.
5500 They are not in the network anymore. Affected file is
5503 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5505 * Implemented the sending of the SERVER_SIGNOFF notify in the
5506 server. Affected file is silcd/server.c.
5508 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
5509 Added also silc_notify_payload_encode_args into the
5510 lib/silccore/silcnotify.[ch].
5512 * Implemented ther SERVER_SIGNOFF notify handling in the server.
5513 Affected file silcd/packet_receive.c.
5515 * Implemented the SERVER_SIGNOFF notify handling in the client
5516 library. Affected file lib/silcclient/client_notify.c. Also,
5517 implemnted the printing of the SERVER_SIGNOFF info to the
5518 application. Affected file silc/client_ops.c.
5520 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
5521 if the deleting was successful. Affected file silcd/idlist.[ch].
5523 * Added support for public key authentication in the connection
5524 authentication protocol in the client library. Affected file
5525 lib/silcclient/protocol.c.
5527 * Changed the server's silc_idlist_get_clients_by_* interface
5528 to support already allocated array so that new entries may be
5529 added to pre-allocated array. Affected file silcd/idlist.[ch].
5530 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
5531 and command replies.
5533 * All command reply functions in the server now calls the
5534 pending command callback even if error occured. This way the
5535 error will be delivered to the client as well. Affected files
5536 silcd/command.c and silcd/command_reply.c.
5538 * Fixed INFO command to return local server's info if no server
5539 was provided. Affected file lib/silcclient/command.c.
5541 * Removed RESTART command for good. Updated the code and the
5544 * Rewrote parts of the task system. It is a bit simpler now.
5545 Removed unsued task priorities. The affected files are
5546 lib/silcutil/silctask.[ch].
5548 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5550 * Moved the USERS printing from the library to the application.
5551 Affected files lib/silcclient/command.c and silc/client_ops.c.
5553 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5557 * Added channel key re-key support. The re-key is perfomed
5558 only by the router and is done once in an hour. Added `rekey'
5559 field to the SilcChannelEntry in the server. Affected files
5560 silcd/server.c and silcd/idlist.h.
5562 * Added silc_task_unregister_by_context into the file
5563 lib/silcutil/silctask.[ch].
5565 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5567 * Added SILC_UMODE_GONE mode to indicate when the client is not
5568 present in the SILC network. Added also support to the local
5569 command AWAY that will set this mode. Added support of showing
5570 "xxx is gone" in WHOIS command. The USERS command shows the
5571 gone status as well.
5573 * Fixed setting server and router operator privileges in the
5574 server's UMODE command. Affected file silcd/command.c.
5576 * Merged the SKE KE1 and KE2 payloads into one payload. The
5577 new KE payload is equivalent to the old KE2 payload.
5579 Cleaned up the SKE Start Payload parsing. It now uses the
5580 simple buffer unformatting to do the parsing. A lot faster
5583 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
5584 to the SKE that is used to indicate whether both of the SKE
5585 parties should perform authentication. By default only the
5586 responder performs authentication. By setting this flag also
5587 the initiator must do authentication. By default it is unset
5588 since in normal SKE case, client to server connection, only
5589 the responder should do authentication. When doing SKE between
5590 two clients both should perform authentication. Updated the
5591 code and the protocol specs.
5593 * A little fix to IDENTIFY command in the server. Search the
5594 client first by hash not nickname. Affected file is
5597 * Fixed the silc_client_close_connection to support closing
5598 the client to client connections wihtout deleting too much
5599 data. Affected file lib/silcclient/client.c.
5601 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
5602 are received if protocol used to be active but is not anymore
5603 the application would crash due to NULL pointer dereference.
5604 Affected files silcd/server.c and lib/silcclient/client.c.
5606 * Added `hash' field to the SilcClientConnection to include
5607 the hash function negotiated in the SKE protocol.
5609 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
5610 to set the channel founder authentication data. A client can
5611 claim the founder rights later by providing the authentication
5612 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
5613 This way the channel founder can regain the channel founder
5614 privileges even it is left the channel. This works only on
5615 local server and the client must be connected to the same
5616 server to be able to regain the founder rights. Updated the
5617 protocol specs accordingly.
5619 Added support to the CMODE command in the client to set the
5620 founder auth data. Read the README to see how to set it.
5622 Added support to the CUMODE command to claim the founder
5623 rights. Read the README to see how to do it.
5625 Added support for the founder authentication to the Channel
5626 Entry in the server. Affected file silcd/idlist.h.
5628 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
5629 server's CMODE command. Affected file silcd/command.c.
5631 * Added the following new functions into lib/silccore/silcauth.[ch]:
5632 silc_auth_get_method and silc_auth_get_data.
5634 * The server now saves the remote hosts public key to the
5635 SilcIDListData pointer. Affected file silcd/protocol.c.
5637 * The normal server now does not remove the channel entry from
5638 the cache if the founder authentication data is set. It used
5639 to remove it if the founder was the last one on the channel on
5640 the server and left the channel. The auth data is saved and
5641 if the channel is re-joined later the old entry is used with
5642 the old auth data. Affected files silcd/command_reply.c and
5645 * Removed the `pkcs' field from the SilcIDListData structure
5646 in the server; it is not used. Affected file silcd/idlist.h.
5648 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5650 * Fixed packet processing on slow links. Partial packets were
5651 never re-processed because the incoming data buffer was cleared
5652 by the application. Application must not directly clear the
5653 sock->inbuf, the packet processing routines handle it. Fixed
5654 this in client library and in server.
5656 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5658 * Fixed the WHOIS and IDENTIFY send reply function to really
5659 check whether to send list or just one entry. Affected file
5662 * Cleaned up the LEAVE command's channel key distribution. The
5663 affected file silcd/command.c.
5665 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
5666 can enforce the channel mode as well. In that case the ID
5667 includes the ID of the server. The code now enforces the
5668 mode change if the router have different mode than the server.
5670 * The notify client operation with CMODE_CHANGE notify can now
5671 return NULL client_entry pointer if the CMODE was not changed
5672 by client. Application must check for this.
5674 * Added <Server ID> argument to INFO command to support server
5675 info fetching by Server ID.
5677 * Added silc_server_announce_get_channel_users to get assembled
5678 packets of channel users of the specified channel. Affected
5679 file silcd/server.[ch].
5681 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
5682 was freed underneath the ID Cache.
5684 * Re-announce clients when the server received CHANNEL_CHANGE
5685 notify from the router. Affected file silcd/packet_send.c.
5687 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5689 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
5690 crashed since it did not handle the fact that there is no cipher
5691 called "3" and didn't check the error condition. Now fixed.
5693 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
5694 flag. It can be used to send message requests.
5696 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5698 * Implemented the RESTART command in the client.
5700 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
5701 notice type messages. Added notice printing to the user
5704 * The channel keys are not re-generated if the channel's mode
5705 is PRIVKEY, ie private key on the channel exists. Affected
5706 files silcd/server.c and silcd/command.c.
5708 * Fixed a little bug in channel message delivery when channel
5709 private keys are set in the server. Affected file is
5710 silcd/packet_send.c.
5712 * Changed the setting on channel->on_channel = TRUE from the
5713 silc_client_save_channel_key to the JOIN command reply. The
5714 key payload is not received if the private channel key is set.
5715 Affected file lib/silcclient/command_reply.c and the
5716 lib/silcclient/client_channel.c.
5718 * When the CMODE_CHANGE notify is sent and the channel private
5719 key mode is removed the channel key must be re-generated in
5720 other cells as well. Added this support for the router in the
5721 silcd/packet_receive.c.
5723 * Added new local command NOTICE to send notice message on
5724 channel. Affected file silc/local_command.[ch].
5726 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5728 * Added new local command ME to the client. It is used to send
5729 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
5730 some action. Affected file silc/local_command.[ch].
5732 * Changed channel_message and private_message client operations
5733 to deliver the message flags to the application. Added also
5734 the `flags' arguments to the silc_client_send_channel_message
5735 and silc_client_send_private_message functions. Affected file
5738 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5740 * Redefined the Private Message Payload to support private message
5741 keys and to support the new private message flags. Updated
5742 the protocol specs. Flags makes it possible to have for example
5743 CTCP style messages.
5745 * Added new type SilcPrivateMessagePayload and defined an API
5746 for it in the lib/silcclient/silcprivate.[ch].
5748 * Tested private message private keys successfully. Tested the
5749 private message key set, unset and list commands with the new
5752 * Redefined the Channel Message Payload to include the channel
5753 message flags (equal with private message flags) to support
5754 for example CTCP style messages.
5756 * Defined some of the message (for channel and private message)
5757 flags. Updated the protocol specs and added the flags to the
5758 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5760 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5762 * Added SilcKeyAgreementStatus type to the key agreement routines
5763 to indicate the current status and error if one occured.
5764 The status types are defined in the lib/silcclient/silcapi.h.
5766 * Added new local command KEY that is used to set and unset private
5767 keys for channels, set and unset private keys for private messages
5768 with remote clients and to send key agreement requests and
5769 negotiate the key agreement protocol with remote client. The
5770 key agreement is supported only to negotiate private message keys,
5771 it currently cannot be used to negotiate private keys for channels,
5772 as it is not convenient for that purpose.
5774 * Fixed a minor pending callback setting bug in the function
5775 silc_client_get_client_by_id_resolve, now the function works.
5776 Affected file lib/silcclient/idlist.c.
5778 * Added function silc_net_get_local_port to get local bound
5779 port by socket. Added to lib/silcutil/silcnet.[ch].
5781 * Added `sockets' and `sockets_count' fields to the SilcClient
5782 object. They hold the sockets of the listenning sockets in
5783 the client. Listenning sockets may be for example the key
5784 agreement server. Affected file lib/silcclient/client.[ch].
5785 Added functions the silc_client_add_socket and the
5786 silc_client_del_socket. They are exported to the application
5789 * Added ~./silc/clientkeys to support other client's public keys.
5791 * Renamed verify_server_key client operation to verify_public_key
5792 and added one argument to indicate the type of the connection
5793 (server, client etc.).
5795 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5797 * Added silc_server_connection_auth_request to handle the
5798 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5799 silcd/packet_receive.[ch].
5801 * Added silc_server_send_connection_auth_request into the
5802 silcd/packet_send.c to send the connection auth request packet.
5804 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5807 * Fixed the public key authentication in responder side in the
5808 server. The `auth_data' pointer includes the SilcPublicKey
5809 not the path to the public key. Affected file silcd/protocol.c.
5811 * Implemented the public key authentication in the initiator side
5812 in the server. Affected file silcd/protocol.c.
5814 * Removed the [RedirectClient] config section from the server
5815 configuration. Is not needed and I don't want to implement it.
5817 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5819 * Cleaned up the CMODE command in the server. It now works
5820 correctly and supports all the modes defined in the protocol.
5821 Affected file is silcd/command.c.
5823 * Added `hmac_name' field to the SilcChannelEntry in the server
5824 to hold the default HMAC of the channel. It can be set when
5825 creating the channel (with JOIN command). Affected files
5828 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5829 type to indicate the change of the current cipher and hmac
5830 on the channel. Client can safely ignore the <cipher> argument
5831 (if it chooses to do so) since the CHANNEL_KEY packet will
5832 force the channel key change anyway. The <hmac> argument is
5833 important since the client is responsible of setting the new
5834 HMAC and the hmac key into use.
5836 * Fixed the CMODE command in the client library as well.
5838 * Tested CMODE command in router environment successfully.
5840 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5842 * Show the version of the remote client (or server) when connecting
5843 to the server. It is logged to the log file. Affected file
5844 is silcd/protocol.c.
5846 * Fixed the KILLED notify handling in the client library. The
5847 client must be removed from all channels when receiving the
5850 Also, do not remove the client entry when giving the KILL
5851 command but when the KILLED notify is received.
5853 * Removed silc_idlist_find_client_by_nickname from the server.
5854 Not needed anymore. Affected files silcd/idlist.[ch].
5856 * Implemented the CHANNEL_CHANGE notify type handling to the
5857 server. Affected file silcd/server.c.
5861 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5863 * Added silc_server_send_notify_invite to send the INVITE
5864 notify between routers.
5866 * Implemented the INVITE command correctly to the server.
5868 * Implemented the INVITE notify type handling in the server.
5870 * Implemented the INVITE command to the client library and on the
5873 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5875 * Added function silc_server_get_client_resolve to find the
5876 client entry by ID from all ID lists and then resolve it
5877 (using WHOIS) if it cannot be found. Affected file is
5880 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5882 * Implemented the BAN command to the client library.
5884 * The JOIN command in the server now checks the invite list
5887 * Changed the silc_command_reply_payload_encode_va and the
5888 silc_command_payload_encode_va to support that if argument is
5889 NULL it ignores and checks the next argument. Affected file
5890 lib/silccore/silccommand.c.
5892 * Added silc_server_send_notify_ban to send the BAN notify
5893 type between routers.
5895 * Chaned the silc_notify_payload_encode to support that if
5896 argument is NULL it ignores and checks the next argument.
5897 Affected file lib/silccore/silcnotify.c.
5899 * Tested ban lists in router environment successfully.
5901 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5903 * Implemented BAN command to the server, in silcd/command.[ch].
5905 * Removed the BAN and INVITE_LIST modes from the CMODE command
5908 * Added function silc_string_match to regex match two strings.
5909 Affected files lib/silcutil/silcutil.[ch].
5911 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5913 * Redefined parts of the SilcChannelEntry in the server to support
5914 the new ban and invite lists.
5916 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5918 * Redefined the INVITE command. The same command can be used to
5919 invite individuals to the channel but also to manage the invite
5920 list of the channel (to add to and remove from the invite list).
5921 Updated the protocol specs.
5923 * Added new command SILC_COMMAND_BAN that can be used to manage
5924 the ban list of the channel. Updated the protocol specs.
5926 * Removed the channel modes: the SILC_CMODE_BAN and the
5927 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5928 in the CMODE command. The equivalent features are now available
5929 using INVITE and BAN commands. Updated the protocol specs.
5931 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5932 in the network about change in the current ban list. The notify
5933 type is not used by the client.
5935 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5936 support the invite lists.
5938 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5940 * Added new function silc_string_regexify that converts string
5941 including wildcard characters into regex string that can
5942 be used by the GNU regex library. Added into the file
5943 lib/silcutil/silcutil.[ch].
5945 Added silc_string_regex_combine to combine to regex strings
5946 into one so that they can be used as one regex string by
5947 the GNU regex library. Added into the file
5948 lib/silcutil/silcutil.[ch].
5950 Added silc_string_regex_match to match two strings. It returns
5951 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5953 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5955 * Imported GNU regex to the soruce tree into lib/contrib.
5956 Fixed some compiler warning from the regex.c.
5958 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5960 * Fixed MOTD command in the server to work in router environment.
5962 * Fixed the MOTD command in the client library to support
5963 the server argument in the command.
5965 * Added `nickname_len' argument to the silc_idlist_add_client
5966 in the server, as the `nickname' argument may be binary data
5969 * Added silc_idlist_get_channels to return all channels from
5972 * Implemented LIST command to the server. Affected file is
5975 * Implemented the LIST command to the client library and on the
5978 * Added [<user count>] argument to the LIST command reply.
5979 With private channels the user count is not shown.
5981 * Updated TODO and README.
5983 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5985 * The client entry's data.registered must be TRUE even with
5986 global client entry on global client list. The data.registered
5987 is used to check whether the client is anymore in the network,
5988 for example with WHOWAS command so it must be valid.
5990 * Fixed the WHOWAS command in the server. It now actually works
5991 in router environment. Added function into silcd/command_reply.c
5992 silc_server_command_reply_whowas_save.
5994 * Added silc_idlist_purge function to the silcd/idlist.c
5995 to periodically purge the ID Cache.
5997 * Fixed INFO command in the server. It works now in router
5998 environment. Added <server name> argument to the INFO command
5999 reply. Updated the protocol specs.
6001 * Fixed minor bug in silc_idcache_purge to not purge if the
6002 expire value is zero.
6004 * Fixed various bugs in WHOIS and IDENTIFY command handling as
6005 they were buggy because of the WHOWAS information.
6007 * Fixed local command MSG to handle the async resolving of
6008 the remote client properly. It used to fail the first MSG.
6009 Affected file silc/local_command.c.
6011 * Added `data_len' field to SilcIDCache context.
6013 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6015 * Update TODO. Todo in commands in the server.
6017 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6019 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
6020 used by routers as broadcast packet to inform other routers
6021 about the changed user mode.
6023 Implemented the notify handling in the server. Affected file is
6024 silcd/packet_receive.c. Added the function
6025 silc_server_send_notify_umode to the silcd/packet_send.[ch].
6027 * Added new generic Channel Payload and deprecated the New Channel
6028 Payload. The New Channel Payload is now the generic Channel
6031 * Added new argument `mode' to the silc_server_send_new_channel
6032 as it is required in the Channel Payload now.
6034 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
6035 and created a new and real SilChannelPayload to represent the
6036 new generic Channel Payload. Implemented the encode/decode
6037 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
6039 * Added silc_server_get_client_channel_list to return the list
6040 of channels the client has joined for WHOIS command reply.
6041 Affected file silcd/server.[ch].
6043 * Implemented the channel list sending in the WHOIS command reply
6044 in server and in the client.
6046 Implemented the channel list displaying on the user interface
6047 as well. Affected file silc/client_ops.c.
6049 * Added silc_channel_payload_parse_list to parse list of Channel
6050 Payloads. It returns SilcDList list of SilcChannelPayloads.
6051 Client for example can use this function to parse the list of
6052 channels it receives in the WHOIS command reply. The caller
6053 must free the list by calling silc_channel_payload_list_free.
6054 Affected files lib/silccore/silcchannel.[ch].
6056 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6058 * Added one new argument <user mode> to the WHOIS command reply
6059 to return the mode of the user in SILC. Updated the protocol
6062 Implemented it to the server and client.
6064 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6066 * Fixed the mode printing on the user interface on joining.
6067 Affected file silc/client_ops.c.
6069 * Implemented the UMODE command and user modes in general to the
6070 client library and to the user interface.
6072 * Implemented the UMODE command to the server.
6074 * The server now sends UNKNOWN_COMMAND error status if client sends
6075 unknown command. Affected file silcd/command.c.
6077 * All server commands now handle the command identifier the right
6078 way when sending the command reply to the client. The client can
6079 use to identify the command replies with the identifier.
6081 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6083 * Added silc_server_get_client_route to resolve the route to
6084 the client indicated by the client ID. Affected file is
6087 * Added silc_server_relay_packet as general function to relay
6088 packet to arbitrary destination. This deprecates functions
6089 like _send_private_message_key, _relay_notify etc. Affected
6090 file is silcd/packet_send.[ch].
6092 Removed silc_server_send_key_agreement,
6093 silc_server_send_private_message_key and
6094 silc_server_packet_relay_notify functions from the file
6095 silcd/packet_send.[ch].
6099 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
6100 server. Affected file silcd/packet_receive.[ch].
6102 * Implemented the KILL command to the client. Implemented the
6103 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
6104 Affected files lib/silcclient/command[_reply].c and
6105 lib/silcclient/client_notify.c. Implemented the KILL notify
6106 printing in the user inteface.
6108 * Fixed a lot silc_parse_nick memory leaks from the client
6109 library in the file lib/silcclient/command.c.
6111 * Changed the silc_server_send_notify_on_channels's `sender'
6112 argument from SilcSocketConnection to SilcClientEntry to
6113 check the sender as entry and not as connection object and not
6114 to send to the client provided as argument. The affected file
6115 is silcd/packet_send.[ch].
6117 * The notify packets that are destined directly to the client used
6118 to not to be processed by the server. Now changed that and the
6119 server processes all notify packets. After relaying the packet
6120 to the client the notify packet is processed in the server.
6122 * The silc_server_free_client_data now checks whether there is
6123 pending outgoing traffic for the client and purges the data to
6124 the network before removing the client entry.
6126 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6128 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
6129 an client is killed from the SILC Network. Updated the protocol
6132 Added new function silc_server_send_notify_killed to the
6133 silcd/packet_send.[ch].
6135 * Added function silc_server_packet_relay_notify to relay notify
6136 packets that are destined directly to a client. In this case
6137 the server does not process the notify packets but merely relays
6138 it to the client. Affected file silcd/packet_send.[ch].
6140 Added also silc_server_packet_process_relay_notify to check
6141 whereto relay the notify. Affected file is
6142 silcd/packet_receive.[ch].
6144 * Implemented the KILL command to the server.
6148 * Added the backup schema desgined last fall to the protocol
6149 specs for everyone to see. The specification is in the
6150 *-spec-xx.txt draft and the packet type definitions for the
6151 backup routers is in *-pp-xx.txt draft. Thusly, added also
6152 new packet type SILC_PACKET_CELL_ROUTERS.
6154 * A big security problem in the implementation discovered. The
6155 signoff of an client did not cause new channel key generation
6156 which it of course should've done. The channel keys must be
6157 always re-generated when client leaves (or signoffs) the channel.
6158 The silc_server_remove_from_channels funtion now handles
6159 the channel key re-generation.
6161 * Added `sender' argument to the silc_server_send_notify_on_channels
6162 to not to send the client provided as argument. Affected file
6163 silcd/packet_send.[ch].
6165 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6167 * Implemented OPER and SILCOPER commands into the server and
6170 * Added silc_auth_verify and silc_auth_verify_data to verify
6171 the authentication directly from the authentication payload.
6172 It supports verifying both passphrase and public key based
6173 authentication. Affected file lib/silccore/silcauth.[ch].
6175 * Added `hash' field to the SilcIDListData structure. It is the
6176 hash negotiated in the SKE protocol. Affected file is
6179 * Slight redesigning of the SilcAuthPayload handling routines.
6180 Do not send SilcPKCS but SilcPublicKey as argument.
6182 * Implemented the public key authentication support to the
6183 serverconfig. The public key is loaded from the provided path
6184 and saved as authentication data to void * pointer. Thus,
6185 changed the unsigned char *auth_data to void *auth_data;
6187 * Fixed SHUTDOWN command to send the reply before the server
6188 is shutdown. :) Affected file silcd/command.c.
6190 * Fixed fatal bug in CONNECT command. The hostname was invalid
6191 memory and server crashed. Affected file silcd/command.c.
6193 * Fixed fatal bug in CLOSE command. The server_entry became
6194 invalid but was referenced later in the command. Affected file
6197 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6199 * Fixed fatal bug in failure packet handling. Server ignored
6200 the failure and thus crashed when it came.
6204 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6206 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
6207 that the command may be executed only once in (about) 2 seconds.
6208 The old SILC_CF_LAG flag is same but allows command bursts up
6209 to five before limiting.
6211 Added the support for CF_LAG and CF_LAG_STRICT flags to the
6212 server code. Various commands now includes the CF_LAG_STRICT
6213 flag to disallow any kind of miss-use of the command.
6215 * Fixed the silc_buffer_unformat to not to allocate any data
6216 if the length of the data is zero. It used to allocate the
6217 length + 1. Affected file lib/silcutil/silcbuffmt.c.
6219 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6221 * Changed the format of AdminConnection configuration section
6222 in the server. Added username of the admin to the format.
6223 Affected files silcd/serverconfig.[ch].
6225 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
6226 to return admin configuration data by host, username and/or
6229 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6231 * Implemented WHOWAS command to the server. Added the functions:
6233 silc_server_command_whowas_parse,
6234 silc_server_command_whowas_send_reply,
6235 silc_server_command_whowas_from_client and
6236 silc_server_command_whowas_from_server
6238 * Added <Client ID> argument to the WHOWAS command reply. Updated
6239 the protocol specs accordingly.
6241 * Implemented WHOWAS command and command_reply to the client
6244 Implemented the WHOWAS printing on the user interface.
6246 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6248 * Added new argument to the WHOWAS command reply, the real name.
6249 It is an optional argument. Updated the protocol specs.
6251 * Added SilcIDCacheDestructor callback that is registered when
6252 the SilcIDCache is allocated. The callback is called when
6253 an cache entry in the ID Cache expires, or is purged from the
6254 cache. Added into lib/silccore/idcache.[ch].
6256 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
6257 to destruct the client entries when the cache entry expires.
6258 Other ID Cache's in server and in the client library ignores
6261 * If the ID Cache entry's `expire' field is zero then the entry
6262 never expires. Added boolean `expire' argument to the
6263 silc_idcache_add function in the lib/silccore/idcache.[ch].
6264 If it is TRUE the default expiry value is used.
6266 * Added silc_server_free_client_data_timeout that is registered
6267 when client disconnects. By default for 5 minutes we preserve
6268 the client entry for history - for WHOWAS command.
6270 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6272 * Added support to the server to enforce that commands are not
6273 executed more than once in 2 seconds. If server receives
6274 commands from client more frequently, timeout is registered
6275 to process the commands. Affected file silcd/command.c.
6276 Added new function silc_server_command_process_timeout.
6278 * Changed NICK_NOTIFY handling in client library to check that
6279 if the client's nickname was changed, so there is no need to
6280 resolve anything from the server.
6282 * Removed error printing from the WHOIS and IDENTIFY commands.
6283 If error occurs then it is ignored silently in the client library.
6284 The application, however, may map the received error to
6285 human readable error string. The application currently maps
6286 the NO_SUCH_NICKNAME error to string.
6288 * Made the command status message public to the application. Moved
6289 them from lib/silcclient/command_reply.c to
6290 lib/silcclient/command_reply.h. The application can map the
6291 received command status to the string with the
6292 silc_client_command_status_message function.
6294 * Added check to the server to check that client's ID is same
6295 as the Source ID in the packet the client sent. They must
6298 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6300 * Added dist-bzip hook to the Makefile.am to make bzip2
6301 compressed distributions.
6303 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6305 * Server now enforces the maximum length for the nickname and
6306 the channel as protocol specification dictates. 128 bytes for
6307 nickname and 256 bytes for channel name.
6309 * Moved the WHOIS printing to the application. The client libary
6310 does not print out the WHOIS information anymore, the application
6311 must do it. Renamed silc_client_command_reply_whois_print to
6312 the silc_client_command_reply_whois_save.
6314 The client's idle time is also sent to the application now, and
6315 the idle is shown on screen.
6317 * Added silc_client_command_reply_identify_save to save the
6318 received IDENTIFY entries.
6320 * Do not check for channel private keys in message sending and
6321 reception if the channel does not have the PRIVKEY mode set.
6322 Affected file lib/silclient/client_channel.c.
6324 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6326 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
6327 just surfaced after chaning the JOIN procedure.
6329 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6331 * Added silc_client_get_clients_by_list to get client entries
6332 from Client ID list, that is returned for example by JOIN
6333 and USERS command replies. The application should use this
6334 function for example when JOIN command reply is received to
6335 resolve the clients already on the channel (library does not
6336 do that anymore as USERS command reply is not used in the JOIN
6337 procedure anymore). Affected files lib/silcclient/silcapi.h and
6338 lib/silcclient/idlist.c.
6340 * JOIN command reply and USERS command reply returns now SilcBuffer
6341 pointers instead of unsigned char pointers when returning
6342 the client list and mode list.
6344 * Added <Client ID> argument to the JOIN command reply, mainly
6345 for the server to identify for which client the command was
6346 originally sent. Updated protocol specs accordingly.
6348 * Added SilcDlist private_key pointer to the SilcChannelEntry
6349 in the client to support the channel private keys. Affected
6350 file is lib/silcclient/idlist.h.
6352 * Added SilcChannelPrivateKey argument to the function
6353 silc_client_send_channel_message so that application can choose
6354 to use specific private ke if it wants to. If it is not provided,
6355 the normal channel key is used, unless private keys are set.
6356 In this case the first (key that was added first) is used
6357 as the encryption key.
6359 * Implemented the support for channel private key handling.
6360 Implemented the following functions:
6362 silc_client_add_channel_private_key,
6363 silc_client_del_channel_private_keys,
6364 silc_client_del_channel_private_key,
6365 silc_client_list_channel_private_keys and
6366 silc_client_free_channel_private_keys
6368 Affected file lib/silcclient/client_channel.c.
6370 * Added the support for the private keys in the channel message
6371 sending and encryption and in the message reception and
6372 decryption. Affected funtions are
6373 silc_client_send_channel_message and silc_client_channel_message.
6375 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6377 * Added SKE's key verify callback to the client library's
6378 KE protocol context. Affected files lib/silcclient/protocol.[ch].
6380 * Removed the statement that server (or router) must send USERS
6381 command reply when joining to the channel so that the client
6382 knows who are on the channel. Instead, the client list and
6383 client's mode list is now sent in the JOIN command reply to the
6384 client who joined channel. This is better solution.
6386 * Added function silc_server_get_users_on_channel and function
6387 silc_server_save_users_on_channel to the silcd/server.[ch].
6389 * Removed function silc_server_command_send_users from the
6392 * Do not show topic on the client library anymore. The topic is
6393 sent in the command reply notify to the application and the
6394 application must show the topic now.
6396 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6398 * Added client searching by nickname hash into the IDENTIFY and
6399 WHOIS commands in the server as they were clearly missing from
6400 them. Affected file is silcd/command.c.
6402 * Fixed a bug in private message receiving in the client library.
6403 The remote ID was freed and it wasn't supposed, now it is
6406 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6408 * Minor fix to the channel payload; allocate the data area, as it
6409 needs to be of specific length.
6411 * If the key agreement port is zero then the operating
6412 system will define the bound port. Affected files are
6413 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
6415 * Added new function silc_channel_payload_decrypt into the file
6416 lib/silccore/silcchannel.[ch].
6418 * Moved the channel message etc, check from silc_packet_decrypt
6419 to applications. The library calls now a generic
6420 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
6421 when the packet is either normal or special. This was done to
6422 allow more wide range of checking that was not allowed when
6423 the code was in library. Now applications can do virtually any
6424 checks to the packet and return to the library the decision how
6425 the packet should be processed. Affected files are
6426 lib/silccore/silcpacket.[ch].
6428 Added silc_server_packet_decrypt_check to the server and
6429 silc_client_packet_decrypt_check to the client library.
6431 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
6432 to send with specified source and destination information.
6434 * Channel message delivery between routers was broken after the
6435 channel key distribution was fixed earlier. The channel key
6436 was used be to distributed to other routers as well which is not
6437 allowed by the protocol. Now this is fixed and channel keys
6438 really are cell specific and the channel message delivery between
6439 routers comply with the protocol specification.
6441 * Fixed various commands in server to check also the global list
6442 for the channel entry and not just the local list. The affected
6443 file silcd/command.c.
6445 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6447 * Added assert()s to buffer formatting and unformatting routines
6448 to assert (if --enable-debug) when error occurs. Affected
6449 file: lib/silcutil/silcbuffmt.c.
6451 * Changed to auto-reconnect to check whether the remote host is
6452 router and register the re-connect timeout if it is. It used
6453 to check that whether we are normal server, but router must do
6454 auto-reconnect with another router as well. Affected file
6457 * Removed the [<key len>] option from CMODE command as the cipher
6458 name decides the key length, nowadays. See the defined ciphers
6459 from the protocol specification.
6461 * Added [<hmac>] option to the CMODE command to define the HMAC
6462 for the channel. Added SILC_CMODE_HMAC channel mode.
6464 * Added [<hmac>] option for the JOIN command so that user can
6465 select which HMAC is used to compute the MACs of the channel
6468 * Added Hmac field to the Channel Message Payload. The integrity
6469 of plaintext channel messages are now protected by computing
6470 MAC of the message and attaching the MAC to the payload. The
6471 MAC is encrypted. Now, it is clear that this causes some
6472 overhead to the size of the packet but rationale for this is that
6473 now the receiver can verify whether the channel message decrypted
6474 correctly and also when private keys are set for the channel the
6475 receiver can decrypt the packet with several keys and check from
6476 the MAC which key decrypted the message correctly.
6478 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
6479 lib/silccrypt/silccipher.[ch].
6481 * Added silc_hash_len to return the digest length into the
6482 lib/silcrypt/silchash.[ch].
6484 * Rewrote parts of Silc Channel Payload interface in the
6485 lib/silccore/silcchannel.[ch]. The encode function now also
6486 encrypts the packet and parse function decrypts it.
6488 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6490 * Fixed a minor formatting bug in the SKE's key material processing.
6491 It actually might have processed the keys wrong way resulting
6494 * Redefined the mandatory HMAC algorithms and added new algorithms.
6495 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
6496 and hmac-md5 truncated to 96 bits. The mandatory is now
6497 hmac-sha1-96. Rest are optional (including the one that used
6498 to be mandatory). Rationale for this is that the truncated HMAC
6499 length is sufficient from security point of view and can actually
6500 make the attack against the HMAC harder. Also, the truncated
6501 HMAC causes less overhead to the packets. See the RFC2104 for
6504 * Added new [hmac] configuration section. The SKE used to use
6505 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
6506 is of course wrong. The official names that must be proposed in
6507 the SKE are the ones defined in the protocol specification
6508 (hmac-sha1-96 for example). The user can configure any hmac
6509 using any hash function configured in the [hash] section. At
6510 least, the mandatory must be configured.
6512 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
6514 * Added HMAC list to the SKE proposal list. It has now both
6515 hash algorithm list and HMAC list. This makes the protocol
6516 incompatible with previous versions. The SKE now seems to work
6517 the way it is supposed to work, for the first time actually.
6519 * Defined plain Hash algorithms to the protocol specification.
6522 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6524 * Implemented support for key agreement packets into the server.
6525 Added functions silc_server_key_agreement and
6526 silc_server_send_key_agreement. Other than these functions,
6527 server has nothing to do with this packet.
6529 * Added support for private message key packets into the server.
6530 Added functions silc_server_private_message_key and
6531 silc_server_send_private_message_key.
6535 * Changed the silc_[client|server]_protocol_ke_set_keys to be
6536 called in the protocol's final callback instead in the END
6537 protocol state. This makes a little more sense and in the same
6538 time in client we can use the same protocol routines for normal
6539 key exchange and to key agreement packet handling as well.
6541 * Added to both client's and server's KE protocol context the
6542 SilcSKEKeyMaterial pointer to save the key material. We will
6543 bring the key material to the protocol's final callback by doing
6544 this. The final callback must free the key material.
6546 * Added SKE's packet_send callback into client's KE protocol
6547 context so that the caller can choose what packet sending function
6548 is used. This way we can use different packet sending when
6549 doing normal SKE when doing key agreement packet handling (in
6550 the key agreement packet handling we do not want to encrypt
6553 * Implemented the responder side of the key agreement routines
6554 in the client. The client can now bind to specified port and
6555 accept incoming key negotiation. The key material is passed
6556 to the application after the protocol is over.
6558 * Implemented the processing of incoming Key Agreement packet
6559 in the client. Added function silc_client_key_agreement to
6562 * Implemented the intiator side of the key agreement routines
6563 in the client. The client can now initiate key agreement with
6564 another remote client. The key material is passed to the
6565 application after the protocol is over.
6567 * Created client_keyagr.c to include all the key agreement
6570 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
6571 SILC_TASK_CALLBACK except that it is not static.
6573 * Created client_notify.c and moved the Notify packet handling
6574 from the client.[ch] into that file.
6576 * Created client_prvmsg.c and moved all private message and
6577 private message key routines from the client.[ch] into that file.
6579 * Create client_channel.c and moved all channel message and
6580 channel private key routines from the client.[ch] into that file.
6582 * Changed silc_client_get_client_by_id_resolve to resolve with
6583 WHOIS command instead of IDENTIFY command, in the file
6584 lib/silclient/idlist.c.
6586 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6588 * Implemented the SKE's responder side to the Client library.
6590 * When FAILURE is received to the protocol do not trust it
6591 blindly. Register a timeout to wait whether the remote closes
6592 the connection as it should do it, only after that process the
6593 actual failure. This was changed to both client and server.
6595 * Added client_internal.h to include some of the structures
6596 there instead of client.h in lib/silcclient/.
6598 * Added function silc_task_unregister_by_callback to unregister
6599 timeouts by the callback function.
6601 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6603 * Some "Incomplete WHOIS info" errors has been appearing on the
6604 log files. Took away the entry->userinfo check from WHOIS
6605 reply sending. The entry->userinfo is now " " if client did not
6606 provide one. I thought this was fixed earlier but something
6607 is wrong still. Let's see if the error still appears.
6609 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6611 * Fixed a minor bug in the login when the channel key is
6612 re-generated in the server. It used to generate the key in
6613 wrong order and thus caused problems in the channel traffic.
6615 * Fixed a minor bug in channel key distsribution after
6616 KICK command. The key was not sent to the router even though
6619 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6621 * Added silc_ske_process_key_material_data as generic routine
6622 to process any key material as the SILC protocol dictates. The
6623 function is used by the actual SKE library but can be used by
6624 applications as well. This relates to the private message keys
6625 and the channel private keys since they must be processed the
6626 same way the normal SILC session keys. The protocol dictates
6627 this. Affected files: lib/silcske/silcske.[ch].
6629 Added also silc_ske_free_key_material to free the
6630 SilcSKEKeyMaterial structure.
6632 * Defined silc_cipher_set_key function to set the key for
6633 cipher without using the object's method function. The affected
6634 files: lib/silccrypt/silccipher.[ch].
6636 * Implemented silc silc_client_add_private_message_key,
6637 silc_client_add_private_message_key_ske,
6638 silc_client_del_private_message_key,
6639 silc_client_list_private_message_keys and
6640 silc_client_free_private_message_keys functions in the
6643 Added functions silc_client_send_private_message_key to send
6644 the Private Message Key payload and silc_client_private_message_key
6645 to handle incoming Private Message Key payload.
6647 * Added Cipher field to the Private Message Key payload to set
6648 the cipher to be used. If ignored, the default cipher defined
6649 in the SILC protocol (aes-256-cbc) is used.
6651 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6653 * Removed lib/silcclient/ops.h file.
6655 Redefined parts of the SILC Client Library API. Created new
6656 file silcapi.h that deprecates the ops.h file and defines the
6657 published Client Library API. Defined also private message key
6658 API and channel private key API into the file.
6660 This is the file that the application must include from the
6661 SILC Client Library. Other files need not be included by
6662 the application anymore.
6664 * Added new key_agreement client operation callback and also
6665 defined the Key Agreement library API for the application.
6667 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6669 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
6670 is used by clients to request key negotiation between another
6671 client in the SILC network. If the negotiation is started it
6672 is performed using the SKE protocol. The result of the
6673 negotiation, the secret key material, can be used for example
6674 as private message key.
6676 Implemented the Key Agreement payload into the files
6677 lib/silccore/silauth.[ch].
6679 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6681 * Redefined ciphers for the SILC protocol. Added some new ciphers
6682 and defined the key lengths for the algorithms. Changed the
6683 code accordingly. The default key length is now 256 bits.
6685 * Fixed SKE key distribution function silc_ske_process_key_material
6686 when the key length is more than 128 bits. The default key
6687 length in SILC is now 256 bits.
6689 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
6690 to indicate unsupported algorithm.
6692 * Renamed rijndael.c to aes.c and all functions as well.
6694 * Fixed a long standing channel key setting bug in client library.
6695 Weird that it has never surfaced before.
6697 * Fixed bug in channel deletion. If the entire channel is removed
6698 then it must also delete the references of the channel entry
6699 from the client's channel list as the client's channel entry and
6700 the channel's client entry share same memory.
6702 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6704 * Implemented CONNECT and SHUTDOWN commands in the client.
6706 * Implemented CLOSE command to the client.
6708 * Added the function silc_idlist_find_server_by_name into the
6709 files silcd/idlist.[ch].
6711 Added the function silc_idlist_find_server_by_conn into the
6712 files silcd/idlist.[ch].
6714 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6716 * DIE command was renamed to SHUTDOWN. Updated the both code
6719 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
6720 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
6722 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
6725 * Added function silc_server_create_connection function to create
6726 connection to remote router. My server implementation actually
6727 does not allow router to connect to normal server (it expects
6728 that normal server always initiates the connection to the router)
6729 so the CONNECT command is only good for connecting to another
6732 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6734 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
6735 or some other client was kicked from the channel.
6737 Implemented the handling of the notify type to both client
6740 Implemented silc_server_send_notify_kicked to send the KICKED
6741 notify. It is used to send it to the server's primary router.
6743 * Implemented the KICK command into server and client.
6745 * Added `query' argument to the silc_idlist_get_client function
6746 to indicate whether to query the client from server or not if
6749 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
6750 to indicate that the client is not channel founder.
6754 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6756 * Removed the rng context from SilcPacketContext structure and
6757 changed that the packet routine uses the Global RNG API.
6759 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6761 * Added support for quit message that client can "leave" on the
6762 channel when it quits the SILC. It is ditributed inside the
6763 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6765 Added silc_server_free_client_data that will take the
6766 signoff message as argument.
6768 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6770 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6772 * Updated parts of the protocol specification to keep it up
6775 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6777 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6778 payloads in one packet.
6780 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6781 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6782 use now the new List flag.
6784 * Also deprecated the following packet types: REPLACE_ID,
6785 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6787 * Added list support for Notify packet in server.
6789 * Added silc_server_send_notify_channel_change to send the
6790 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6791 the silc_server_send_replace_id.
6793 * Added silc_server_send_notify_nick_change to send the
6794 NICK_CHANGE notify type. Deprecates the function
6795 silc_server_send_replace_id.
6797 * Added silc_server_send_notify_join to send the JOIN notify type.
6798 Deprecates the function silc_server_send_new_channel_user.
6800 * Added silc_server_send_notify_leave to send LEAVE notify type.
6801 Deprecates the function silc_server_send_remove_channel_user.
6803 * Added silc_server_send_notify_cmode and
6804 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6805 types. Deprecates the silc_server_send_set_mode function.
6807 * Added SERVER_SIGNOFF notify type to indicate that server has
6808 quit. This means that all clients on the channel from that
6809 server will drop. This can be also used when netsplit happens.
6811 Deprecated REMOVE_ID packet type since it is not needed anymore
6814 Added silc_server_send_notify_server_signoff to send the
6815 SERVER_SIGNOFF notify type. Deprecates the function
6816 silc_server_send_remove_id.
6818 Added also silc_server_send_notify_signoff to send the
6819 SIGNOFF notify type.
6821 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6822 SILC protocol from this day on. Changed the protocol
6823 specification as well.
6825 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6826 notify type. It is used between routers to notify about
6827 topic changes on a channel.
6829 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6832 * Partly updated the protocol specification to comply with the
6833 changes now made. It is still though a bit outdated.
6835 * The JOIN notify type now takes one extra argument <Channel ID>.
6836 The packet used to be destined to the channel but now the
6837 JOIN type may be sent as list thus it is impossible to
6838 destine it to any specific channel. By adding this argument
6839 it is again possible.
6841 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6843 * Added CREDITS file. The CHANGES and CREDITS file will appear
6844 in the distribution as well.
6846 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6848 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6849 types in the server's silcd/packet_receive.c.
6851 * Implemented CMODE and CUMODE to work in router environment.
6853 * Fixed minor encoding and decoding buglet from the
6854 lib/silccore/silcmode.c.
6856 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6859 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6861 * Changed all SilcConfigServer* and silc_config_server* to
6862 SilcServerConfig* and silc_server_config*, respectively.
6865 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6867 * Associated the ID (client or server ID) to the Authentication
6868 Payload to avoid any possibility of forging. Updated the
6869 protocol specification and the code accordingly.
6871 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6873 * The RSA key length is now save to the RsaKey context in the
6874 key generation process in lib/silccrypt/rsa.c. The key length
6875 is now used to figure out the maximum size of the block allowed
6876 to be encrypted/signed.
6878 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6879 is equivalent to the silc_mp_mp2bin but does not allocate any
6882 * Changed silc_mp_mp2bin API to take length argument. If it is
6883 non-zero then the buffer is allocated that large. If zero, then
6884 the size is approximated using silc_mp_sizeinbase, which however
6887 * Created Global RNG API which is global RNG that application can
6888 initialize. After initializing, any routine anywhere in the
6889 code (including library) can use RNG without allocating a new
6890 RNG object. This was done to allow this sort of use of the
6891 RNG in code that has no chance to allocate RNG object. All
6892 applications currently allocate this and many routines in the
6893 library use this. Affected file lib/silccrypt/silcrng.[ch].
6895 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6896 it to use the Global RNG API.
6898 * Defined Authentication Payload into protocol specification that
6899 is used during SILC session to authenticate entities. It is
6900 used for example by client to authenticate itself to the server
6901 to obtain server operator privileges.
6903 Implemented this payload into the lib/silccore/silcauth.[ch].
6904 Implemented also routines for public key based authentication
6905 as the new protocol specification dictates.
6907 Moved definitions of different authentication methods from
6908 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6910 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6911 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6912 silc_pkcs_verify_with_hash functions into the file
6913 lib/silccrypt/silcpkcs.[ch].
6915 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6917 * The client entry's userinfo pointer must be always valid.
6918 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6919 will fail since it requires the userinfo. Now, the userinfo
6920 is allocated as "" if actual userinfo does not exist. Actually,
6921 it must exist and it is totally Ok to drop client connections
6922 that does not announce the userinfo. However, we will make
6923 this workaround for now.
6925 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6926 to return the remote port by socket.
6928 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6930 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6931 SILC_SERVER_PENDING_EXEC and added an new macro
6932 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6933 data or when error occurs while processing the pending command.
6935 Added new argument `destructor' into silc_server_command_pending
6936 and to the SilcServerCommandPending object. This destructor is
6937 now called after calling the pending callback or if error occurs
6938 immediately. If error occurs the actual pending callback won't
6939 be called at all - only the destructor. The destructor may be
6940 NULL if destructor is not needed.
6942 All this applies for client library code as well. Similar
6943 changes were made there as well for the pending commands.
6945 In the client, the application must now allocate the
6946 SilcClientCommandContext with the silc_client_command_alloc
6949 * Added reference counter to the SilcServerCommandContext. Added
6950 function silc_server_command_alloc and silc_server_command_dup
6953 Same type of functions added to the client library for the same
6956 * Removed the cmd_ident from IDListData away since it is now
6957 global for all connections. It is the command identifier used
6958 in command sending and with pending commands. The affected file
6961 * Added reference counter to the SilcSocketConnection objecet to
6962 indicate the usage count of the object. The object won't be
6963 freed untill the reference counter hits zero. Currently only
6964 server uses this, and client ignores it. The client must be
6965 set to use this too later. The affected files are
6966 lib/silccore/silcsockconn.[ch]. Added also the function
6967 silc_socket_dup to increase the reference counter.
6969 This was mainly added because it is possible that the socket
6970 is removed underneath of pending command or other async
6971 operation. Now it won't be free'd and proper DISCONNECTING
6972 flags, etc. can be set to avoid sending data to connection that
6973 is not valid anymore.
6975 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6976 the connection. After that it sets SILC_SET_DISCONNECTED.
6977 It is, however, possible that the socket data is not still freed.
6978 The silc_server_packet_process now checks that data is not
6979 read or written to connection that is DISCONNECTED. The socket
6980 get's freed when the reference counter hits zero.
6982 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6984 * Changed the client operation API: channel_message operation's
6985 `sender' is now the client entry of the sender, not the nickname
6986 and the `channel' is the channel entry, not the channel name.
6988 In the private_message operation the `sender' is now also the
6989 client entry of the sender not the nickname.
6991 Affected file is lib/silcclient/ops.h and all applications
6992 using the client operations.
6994 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6996 * Moved the calling of ops->connect() from connect_to_server_final
6997 into receive_new_id functin since that is the point when the
6998 client is actually allowed to send traffic to network. The
6999 affected file is lib/silcclient/client.c.
7001 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7003 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
7004 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
7005 (if needs broadcasting) instead of broadcasting the packets one
7006 by one which would make a burst in the network traffic.
7008 * Added `broadcast' argument to the functions in silcd/server.[ch]
7009 silc_server_create_new_channel[_with_id] to indicate whether
7010 to send New Channel packet to primary router.
7012 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7014 * Added new function into the silcd/server.[ch] files:
7015 silc_server_create_new_channel_with_id to create new channel with
7016 already existing Channel ID.
7018 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
7019 lib/silccore/silcpacket.h. This packet is used t send list of
7020 Set Mode payloads inside one packet. Server uses this to set
7021 the modes for the channels and clients on those channels, that it
7022 announced to the router when it connected to it. The protocol
7023 specification has been updated accordingly.
7025 * The silc_server_new_channel did not handle the packet coming
7026 from normal server as it normally does not send that. However,
7027 when it announces its channels it does send it. Implemented
7028 the support for that.
7030 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
7031 into the file lib/silccore/id.h.
7033 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7035 * Fixed memory leaks in the functions silc_idlist_del_client,
7036 silc_idlist_del_channel and silc_idlist_del_server in the file
7037 silcd/idlist.c. All of those leaked like a sieve.
7039 * Fixed some small memory leaks in the client's function
7040 silc_client_notify_by_server.
7042 * Added functions into silcd/server.c: silc_server_announce_clients,
7043 silc_server_announce_channels and silc_server_announce_server.
7044 These functions are used by normal and router server to announce
7045 to its primary router about clients, channels and servers (when
7046 router) that we own. This is done after we've connected to the
7049 These functions effectively implements the following packet types:
7050 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
7051 and SILC_PACKET_NEW_ID_LIST.
7053 * Added new functions into the silcd/packet_receive.[ch]:
7054 silc_server_new_id_list, silc_server_new_channel_list and
7055 silc_server_new_channel_user_list to handle the incoming
7056 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
7058 * Added support of changing Channel ID in the function
7059 silc_server_replace_id. If the server that announces a channel
7060 to the router already exists in the router (with same name but
7061 with different Channel ID), router is responsible to send
7062 Replace ID packet to the server and force the server to change
7063 the Channel ID to the one router has.
7065 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
7066 client that the Channel ID has been changed by the router. The
7067 normal server sends this to the client. Client must start using
7068 the new Channel ID as the channel's ID.
7070 Implemented handling of this new type into lib/silcclient/client.c
7071 into the function silc_client_notify_by_server.
7073 * Added new function silc_idlist_replace_channel_id into the files
7074 silcd/idlist.[ch] to replace the Channel ID.
7076 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7078 * Call silc_server_command_identify_check always when processing
7079 the IDENTIFY command in silcd/command.c
7081 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7083 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
7084 send keepalive packets. The packet can be sent by clients,
7085 servers and routers.
7087 Added function silc_socket_set_heartbeat into the file
7088 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
7089 If not set, the heartbeat is not performed. The actual
7090 heartbeat is implemented in the low level socket connection
7091 library. However, application is responsible of actually
7094 Added silc_server_send_heartbeat to send the actual heartbeat
7095 packet into silcd/packet_send.[ch]. Server now performs
7096 keepalive with all connections.
7098 * Added silc_task_get_first function into lib/silcutil/silctask.c
7099 to return the timeout task with shortest timeout. There was a bug
7100 in task unregistration that caused problems. TODO has been
7101 updated to include that task system must be rewritten.
7103 * The client library will now resolve the client information when
7104 receiving JOIN notify from server for client that we know but
7105 have incomplete information.
7107 * Rewrote parts of silc_server_remove_from_channels and
7108 silc_server_remove_from_one_channel as they did not remove the
7109 channel in some circumstances even though they should've.
7111 * Encryption problem encountered in server:
7113 The LEAVE command used to send the Channel Key packet to the
7114 router immediately after generating it. However, the code
7115 had earlier sent Remove Channel user packet but not immediately,
7116 ie. it was put to queue. The order of packets in the router
7117 was that Channel Key packet was first and Remove Channel User
7118 packet was second, even though they were encrypted in the
7119 reverse order. For this reason, MAC check failed. Now, this
7120 is fixed by not sending the Channel Key packet immediately but
7121 putting it to queue. However, this is more fundamental problem:
7122 packets that are in queue should actually not be encrypted
7123 because packets that are sent immediately gets encrypted
7124 actually with wrong IV (and thus MAC check fails). So, packets
7125 that are in queue should be encrypted when they are sent to
7126 the wire and not when they put to the queue.
7128 However, the problem is that the current system has not been
7129 designed to work that way. Instead, the packet is encrypted
7130 as soon as possible and left to the queue. The queue is then
7131 just purged into wire. There won't be any fixes for this
7132 any time soon. So, the current semantic for packet sending
7135 o If you send packet to remote host and do not force the send
7136 (the packet will be in queue) then all subsequent packets to the
7137 same remote host must also be put to the queue. Only after the
7138 queue has been purged is it safe again to force the packet
7141 o If you send all packets immediately then it safe to send
7142 any of subsequent packets through the queue, however, after
7143 the first packet is put to queue then any subsequent packets
7144 must also be put to the queue.
7146 Follow these rules and everything works fine.
7148 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7150 * Added new function silc_server_remove_clients_by_server to
7151 remove all client entries from ID list when the server connection
7152 is lost. In this case it is also important to invalidate all
7153 client entires as they hold the invalid server entry. This
7154 fixes fatal bug when server has lost connection and will reconnect
7157 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7159 * Made some sanity checks to silc_server_daemonise like to check
7160 whether the requested user and group actually exists.
7162 * Added sanity check to SKE's silc_ske_responder_finish to check
7163 that the public and private key actually is valid.
7165 * Invalidate the client's nickname when receiving Replace ID
7166 packet and the Client ID is being replaced. This means that the
7167 server will query the nickname if someone needs it (client)
7170 * Sort the ID Cache in client library when the ID Cache data
7171 has changed (needs sorting).
7173 * Do not allow for SILC client to create several connections to
7174 several servers. The client does not support windows right now
7175 and generating multiple connections causes weird behaviour.
7177 Irssi-silc client does support windows and can handle several
7178 connections without problems, see: www.irssi.org and SILC plugin.
7180 * Fixed some places where client was added to the IDList. The
7181 rule of thumb is following (in order to get everything right):
7182 If the client is directly connected local client then the
7183 `connection' argument must be set and `router' argument must be
7184 NULL to silc_idlist_add_client function. If the client is not
7185 directly connected client then the `router' argument must
7186 bet set and the `connection' argument must be NULL to the
7187 silc_idlist_add_client function.
7189 * The funtion silc_server_packet_send_local_channel actually did
7190 not check whether the client was locally connected or not. It
7191 does that now. Fixed a bug related to LEAVE command.
7193 * Fixed Remove Channel User payload parsing bug in server's
7194 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
7196 * The server's silc_server_save_channel_key now checks also the
7197 global ID list for the channel as it might not be in the local
7198 list. Fixed a bug related to LEAVE command.
7200 * Is this the end of the [<unknown>] buglet that has been lurking
7201 around for a long time? A little for loop fix in server's
7202 silc_server_command_whois_parse that is used by both IDENTIFY
7203 and WHOIS command. At least, this was a clear bug and a cause
7204 of one type of [<unknown>] buglet.
7206 * WHOIS and IDENTIFY commands call the function
7207 silc_server_command_[whois/identify]_check function even if
7208 we are not router server.
7210 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7212 * Added --with-gmp configuration option. If set the GMP
7213 is always compiled in the SILC source tree. If not set then
7214 it is checked whether the system has the GMP3 installed. If
7215 it has then the GMP won't be compiled (the system's headers
7216 and library is used), if it doesn't have it then the GMP is
7217 compiled in the SILC source tree.
7219 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7221 * Changed RSA private exponent generation to what PKCS #1
7222 suggests. We try to find the smallest possible d by doing
7223 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
7224 not security fix but optimization.
7226 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7228 * Added new config entry [Identity] to fork the server and run
7229 it as specific user and group. A patch from Bostik.
7231 * Imported Dotconf configuration library into lib/dotconf.
7232 This will be used to create the SILC configuration files later.
7233 It will appear in the distsribution after this commit.
7235 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7237 * A big code auditing weekend happening. Auditing code for
7238 obvious mistakes, bugs and errors. Also, removing any code
7241 Removed files for being obsolete:
7243 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
7244 inline in the file lib/silcutil/silcbuffer.h)
7246 o lib/silcutil/silcbufutil.c (the header has inline versions)
7248 Changed code to fix possible error conditions:
7250 o The buffer formatting routines now check that the destination
7251 buffer really has enough space to add the data. This applies for
7252 both buffer formatting and unformatting
7253 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
7254 unformatting was changed to accomodate following rules:
7255 XXX_*STRING_ALLOC will allocate space for the data into the pointer
7256 sent to the function while XXX_*STRING will not allocate or copy
7257 the data into the buffer. Instead it sets the pointer from the
7258 buffer into the pointer sent as argument (XXX_*STRING used to
7259 require that the pointer must be allocated already). This change
7260 makes this whole thing a bit more consistent and more optimized
7261 (note that the data returned in the unformatting with XXX_*STRING
7262 must not be freed now). The routines return now -1 on error.
7264 o Tried to find all code that use buffer_format and buffer_unformat
7265 and added return value checking to prevent formatting and
7266 especially unformatting errors and possible subsequent fatal
7269 o Changed ske->x and ske->KEY to mallocated pointers in
7270 lib/silcske/silcske.h. Fixed possible data and memory leak.
7272 o Added return value checking to all *_parse* functions. Fixed
7273 many memory leaks as well.
7275 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
7276 so that buffer overflows would not happen. All code now also
7277 checks the return value as it can fail.
7279 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7281 * Added reconnection support to server if the normal server looses
7282 its connection to the router (for example if router is rebooted).
7283 The server performs normal reconnection strategy implemented
7284 to the server. Affected file silcd/server.c.
7286 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7288 * Added new packet type SILC_PACKET_SET_MODE that is used to
7289 distribute the information about changed modes (for clients,
7290 channels and clients channel modes) to all routers in the
7291 network. Updated the protocol specification accordingly.
7293 Added functions into silcd/packet_send.c and
7294 silcd/packet_receive.c: silc_server_send_set_mode,
7295 silc_server_set_mode.
7297 Added new files silcmode.[ch] into lib/silccore that implements
7298 the encoding and decoding of Set Mode Payload. Added new type
7299 SilcSetModePayload. Moved the definitions of different modes
7300 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
7302 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7304 * Oops, a little mistake in server's connection authentication
7305 protocol. The protocol is not ended with FAILURE but with
7306 SUCCESS if the authentication is Ok. :) Affected file is
7309 * Implemented NICK_CHANGE notify handling in server in the file
7310 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
7311 the local clients on the channel. After the changing nickname
7312 in router environment snhould work and the [<unknown>] nickname
7313 should appear no more.
7315 The silc_server_replace_id function that receives the Replace ID
7316 payload now sends the NICK_CHANGE notify type also in the file
7317 silcd/packet_receive.c
7319 * Changed WHOIS and IDENTIFY command to support the maximum amount
7320 of arguments defined in protocol specs (3328 arguments). This
7321 fixed a bug that caused problems when there were more than three
7324 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7326 * Added extra parameter, command identifier, to the
7327 silc_client_send_command so that explicit command identifier
7330 Changed that ID list routines uses specific command identifier
7331 when sending WHOIS/IDENTIFY requests to the server so that they
7332 can be identified when the reply comes back.
7334 Affected files lib/silcclient/command.[ch],
7335 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
7337 * Added `sender' argument to silc_server_packet_send_to_channel
7338 to indicaet the sender who originally sent the packet to us
7339 that we are now re-sending. Ignored if NULL. Affected file
7340 silcd/packet_send.[ch].
7342 * Added some server statistics support in silcd/server_internal.h
7343 SilcServerStatistics structure and around the server code. Also
7344 send some nice statistics information when client is connecting
7347 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7349 * Fixed channel ID decoding in server's JOIN command reply in
7350 silcd/command_reply.c
7352 * Fixed braodcasting of replace ID payload to not to send it if
7353 we are standalone server in silcd/packet_receive.c.
7355 * Fixed all channel message sending routines to not to send
7356 packets to clients that has router set, since they are routed
7357 separately in the same function earlier. Affects file
7358 silcd/packet_send.c and all channel packet sending functions.
7360 * In USERS reply, res_argv[i] are not allocated, the table
7361 is allocated. Thus changed that free the table, not its
7364 * In server's whois_check and identify_check if the client is
7365 locally connected do not send any WHOIS commands - they are not
7368 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7370 * Fixed some minor bugs in client when sending WHOIS command. The
7371 arguments was in wrong order.
7373 * Removed statis function add_to_channel from server in
7374 silcd/command.c that was previously used with the joining but
7377 * Tested USERS command in router environment successfully with two
7378 routers, two servers and two clients.
7380 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7382 * Reorganized the USERS command and command reply in client library
7383 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
7384 When the command is given by user we register a pending command
7385 callback that will reprocess the command after the reply has been
7386 received from the server. When reprocessing the packet we then
7387 display the information. Thus, the USERS information is displayed
7388 now in the command callback instead of in the command reply
7389 callback. The processing of the command is same as previously
7390 when server has sent the command reply in the JOINing process.
7392 * Added to USERS command in silcd/command_reply.c to join the client,
7393 we didn't use to know about, to the channel after we've created
7394 a client entry for it. Also, for clienet we did know already still
7395 check whether it is on the channel or not and add it if not.
7397 * Removed silc_server_command_join_notify as the function and its
7400 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7402 * Changed the client's pending command handling to the same as the
7403 server's pending command handling. It is also now possible to
7404 execute command reply functions from other command reply
7405 function as the function callbacks for commands and command
7406 replies are one and same. The pending commands are not static
7407 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
7408 in client connection context. Thus, pending commands are server
7409 connection specific as it is convenient.
7411 Changed the function silc_client_command_pending and
7412 silc_client_command_pending_del and added new function
7413 silc_client_command_pending_check. Removed the
7414 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
7417 * Added cmd_ident, current command identifier, to the client
7418 connection context in lib/silcclient/client.h to keep track on
7419 command identifiers used in command sending. Client's command reply
7420 function handling now supports the mandatory command identifiers.
7422 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
7423 funtions in client to fully support pending command callbacks.
7425 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
7426 as one of the arguments to the application in the command reply
7429 * NOTE: The FORWARDED flag is depracated. It used to be depracated
7430 before first releasing SILC but came back. Now it is removed again
7431 and should come back nomore. The FORWARDED flag was used only
7432 by the JOINing procedure by forwarding the command packet to router.
7433 Now, the JOINing procedure has been changed to more generic (due
7434 to various router environment issues) and FORWARDED is not needed
7435 anymore for anything. The protocol specification is yet to be
7438 Now, removed silc_server_packet_forward from server and the flag
7439 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
7441 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7443 * Renamed NAMES command to USERS command. The NAMES was named that
7444 due to historical reasons. Now it is renamed. Also, rewrote
7445 parts of the USERS command. The nickname list is not sent anymore
7446 by the server. Only Client ID and mode lists are sent in the USERS
7447 command. Changed this also to the protocol specification.
7449 The client now resolves the names and stuff after it receives
7450 the USERS list from the server when joining to the channel.
7452 * WHOIS and IDENTIFY commands has been changed to support multiple
7453 Client ID's per command. One can now search for multiple users
7454 in the network by sending only one WHOIS or IDENTIFY command.
7455 Changed the code and the protocol specifications.
7457 * Removed silc_server_command_identify_parse and changed that IDENTIFY
7458 uses silc_server_command_whois_parse to parse the request. */
7460 * If normal server, do not parse the WHOIS and IDENTIFY requests
7461 before sending it to the router. Saves some time.
7463 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7465 * Fixed JOIN command on client library. Wrong number of arguments
7466 used to crash the client.
7468 * Added silc_server_channel_has_global function to check whether
7469 channel has global users or not.
7471 * Added silc_server_channel_has_local function to check whether channel
7472 has locally connected clients on the channel.
7474 * The silc_server_remove_from_one_channel now checks whether the
7475 channel has global users or not after given client was removed from
7476 the channel. It also checks whether the channel has local clients
7477 on the channel anymore. If it does not have then the channel entry
7478 is removed as it is not needed anymore.
7480 * The silc_server_notify now checks on JOIN notify whether the joining
7481 client is one of locally connected or global. If it is global then
7482 the channel has now global users on the channel and that is marked
7483 to the channel entry. Also, it now saves the global client to
7484 global list who is joining and JOINs it to the channel. This is
7485 for normal server, that is.
7487 Changed silc_server_send_notify_on_channel,
7488 silc_server_packet_relay_to_channel and
7489 silc_server_packet_send_to_channel check if we are normal server
7490 and client has router set (ie. global client) do not send the
7491 message to that client, as it is already routed to our router.
7493 * Implemented LEAVE notify type handling in silc_server_notify
7496 * Tested LEAVE command in router environment successfully. Tested
7497 with two routers, two servers and two clients.
7501 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
7503 * Implemented SIGNOFF notify type handling in silc_server_notify
7506 * silc_server_remove_id now removes the client entry from all channels
7507 it has joined and thusly sends SIGNOFF notify type.
7509 * Rewrote the NAMES list generation in server by removing two excess
7510 loops. The lists are created now inside one loop.
7512 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7514 * silc_server_remove_channel_user checks now also global list
7515 for channel and client.
7517 * silc_server_new_channel_user checks now both local and global
7518 list for channel and client. Fixed a bug in client id decoding.
7519 Used to decode wrong buffer.
7521 * silc_server_channel_message checks now both local and global
7522 list for channel entry.
7524 * Tested channel joining (hence JOIN) in router environment
7525 successfully. Tested with two routers, two servers and two
7528 * Tested channel message sending in router environment successfully.
7530 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7532 * Added silc_server_save_channel_key into server.[ch] to save the
7533 received channel key in Channel Key payload processing. It is
7534 also used in JOIN command reply handling.
7536 Equivalent function silc_client_save_channel_key added into
7537 client.[ch] into client library.
7539 * Changed JOIN command reply to send information whether the channel
7540 was created or not (is existing already) and the channel key
7541 payload. Changed protocol specs accordingly.
7543 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
7544 the request was sent by ID and not by nickname. Crashed on
7547 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7549 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
7550 now correctly save the received data.
7552 * silc_server_free_sock_user_data now notifies routers in the
7553 network about entities leaving the network.
7555 At the same time implemented functions silc_server_remove_id
7556 and silc_server_send_remove_id to receive and send REMOVE_ID
7557 packets. The packet is used to notify routers in the network
7558 about leaving entities. The ID removed will become invalid in
7561 * Added function silc_idlist_del_server into server. Removes and
7562 free's server entry from ID list.
7564 * silc_server_private_message function now checks, if we are router,
7565 that the destination ID really is valid ID, naturally.
7567 * In router when NEW_ID packet is received (for new client) the
7568 hash of the Client ID is saved in the ID Cache but the
7569 client->nickname is set to NULL, instead of putting the hash
7572 IDENTIFY command now also checks that client->nickname must be
7573 valid. If it is not if will request the data from the server who
7574 owns the client. Added new function
7575 silc_server_command_identify_check.
7577 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
7578 to set the command to already allocated Command Payload.
7580 * Tested private message sending in router environment with two
7581 routers, two servers and two clients. Fixed minor bugs and now
7584 * Fixed segfault from client's NAMES command. Used to crash if
7587 * Forwarded packets must not be routed even if it is not destined
7588 to the receiver. Changed server code comply with this.
7590 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7592 * Added `require_reverse_mapping' boolean value to ServerParams
7593 structure. If TRUE (not default) the server will require that
7594 the connecting host has fully qualified domain name.
7596 If the reverse mapping is not required and hostname could not be
7597 found the IP address is used as hostname.
7599 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7601 * Implemented version string checking to both client and server.
7602 The check is incomplete currently due to the abnormal version
7603 strings used in development version of SILC.
7605 * Changed all command functions in server to use the new
7608 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7610 * Changed char *data to unsigned char *data in ID Cache system to
7611 support binary data as ID Cache data. Changed code to support
7612 binary data in lib/silccore/idcache.c.
7614 * Renamed silc_server_packet_relay_command_reply to
7615 silc_server_command_reply as it is normal packet receiving
7616 function. Rewrote the function to accept command replys for
7617 servers and not only for clients.
7619 * Mark remote router always as registered server if we are connecting
7620 to it. Otherwise, commands sent by the router to us are ignored.
7622 * All ID List find routines now returns the ID Cache Entry pointer
7623 as well if requested.
7625 * WHOIS command works now in router environment, tested with two
7626 routers, two servers and two clients.
7628 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
7629 in router environment (as it is almost equivalent to WHOIS) but
7630 hasn't been tested thoroughly. Added new functions:
7632 silc_server_command_identify_parse
7633 silc_server_command_identify_send_reply
7634 silc_server_command_identify_from_client
7635 silc_server_command_identify_from_server
7637 * Disabled route cache adding because adding two different ID's with
7638 same IP replaces the old cache entry thus giving wrong route.
7639 The entry->router->connection is always the fastest route anyway
7640 so route cache may not be needed. Of course, new routes maybe
7641 established after receiving the ID when the entry->router->connection
7642 might not be anymore the most optimal.
7644 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7646 * Add route cache for received ID for fast routing.
7648 * Added silc_server_packet_route to route received packet on router
7649 that is not destined to us.
7651 * Renamed silc_server_get_route to silc_server_route_get.
7653 * Added id_string and id_string_len fields into SilcServer to
7654 include encoded ServerID for fast comparing without excess
7655 encoding of the ID's.
7657 * Cleaned up WHOIS command on server side. Added following static
7660 silc_server_command_whois_parse
7661 silc_server_command_whois_check
7662 silc_server_command_whois_send_reply
7663 silc_server_command_whois_from_client
7664 silc_server_command_whois_from_server
7666 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
7667 arguments in command replies. All command functions should be
7668 updated to use this macro.
7670 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7672 * Minor typo fixes on command reply handling on server.
7674 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7676 * Added silc_server_command_add_to_channel internal routine to add
7677 the client to the channel after router has created the channel and
7678 sent command reply to the server.
7680 * Added generic silc_server_send_command to send any command from
7683 * Use static buffer with ID rendering instead of duplicating data.
7685 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7687 * Fixed a channel user mode bug when joining to a channel server gave
7688 everybody channel founder rights, oops.
7690 * We mark ourselves as the router of the incoming server connection
7691 if we are router ourselves. This way we can check in some packet
7692 sending functions whether it is locally connected server. For
7693 incoming router connections we put NULL.
7695 * For router sending packets locally means now always sending the
7696 packet cell wide; to local clients and local servers. For normal
7697 server sending packet locally means sending it to only local
7700 * Fixed the JOIN command to really work in router environment. If the
7701 channel is created it is always created by the router. Router is
7702 also responsible of making the initial joining to the channel,
7703 sending JOIN notify to the sending server and distributing
7704 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
7705 does not exist server doesn't do anything else but forward the
7706 command to the router which performs everything.
7708 * Added silc_server_send_channel_key function to send the Channel Key
7711 * Added silc_server_create_channel_key to create new channel key. The
7712 channel key is now re-generated everytime someone joins or leaves
7713 a channel, as protocol dictates. Note: channel->key_len is the
7716 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7718 * Splitted server.[ch] finally. Created now packet_send.[ch] and
7719 packet_receive.[ch] to separate packet sending and receiving
7720 routines. The server.[ch] now includes everything else including
7721 actual packet processing (writing and reading data) and other
7724 Renamed silc_server_private_message_send_internal to
7725 silc_server_send_private_message. The routine is still though
7726 used only to relay private messages as server does not send
7727 private messages itself.
7729 Renamed silc_server_new_channel to silc_server_create_new_channel
7730 and added new function sicl_server_new_channel that handles the
7731 incoming New Channel packet. Added also new sending function
7732 silc_server_send_new_channel to send New Channel Payload.
7734 * Added new function silc_server_notify to process incoming notify
7735 packet to the server/router. Server may then relay the notify
7736 to clients if needed.
7738 * Added new function silc_server_new_channel_user to process incoming
7739 New Channel User packet. Router will redistribute the packet and
7740 send JOIN notify to its local clients and locally connected servers
7741 if needed. Normal server will send JOIN notify to its local client
7742 on same channel when received this packet. Added also corresponding
7743 sending function silc_server_send_new_channel_user to sent the
7746 * Added boolean route argument to send_notif_to_channel and
7747 packet_send_to_channel functions to attempt to route the packet
7748 if it is TRUE and send only locally if it is FALSE.
7750 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7752 * silc_server_replace_id now broadcasts the received replace ID
7753 packet if it is not broadcast packet already. The router must
7754 broadcast to inform other routers about changed ID.
7756 * Added backpointer to server's router into SilcServer context in
7757 silcd/server_internal.h.
7759 * Fixed silc_server_packet_broadcast to send correct broadcast
7762 * The channel key is now distributed to the local client as soon
7763 as it is received from the router (in router environment) so that
7764 no other packet may be sent for the channel until client has
7767 * silc_server_remove_channel_user now broadcasts the received
7768 Remove Channel User packet if it is not broadcast packet already.
7769 The router must broadcast to inform other routers about removed
7772 * Added users field into SilcPacketContext that is a reference count
7773 of the context. One can increase the reference count by calling
7774 silc_packet_context_dup which is now changed to just increase the
7775 reference count instead of duplicating the data. The reference
7776 count is decresed by calling silc_packet_context_free that will
7777 free the data after the reference count hits zero.
7779 For now on the packet context and everything allocated into it
7780 (including the raw packet from network) must be freed by calling
7781 the new silc_packet_context_free function. Added also new function
7782 silc_packet_context_alloc that must be used now to allocate the
7783 context. This also means that if a routine is asynchronous from
7784 silc_[client/server]_packet_parse_type the packet context must
7785 be duplicated by calling silc_packet_context_dup. Otherwise it
7786 gets free'd after silc_[client/server]_packet_parse_type returns.
7787 Also, one must remember that if packet is duplicated then its
7788 reference count must be decresed by calling the free function as
7789 many times as it was duplicated.
7791 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7792 from both client and server.
7794 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7796 * Made joining to a channel working in router environment.
7798 * Cleaned up JOIN command on server side and create function
7799 silc_server_command_join_channel internal routine to make the
7802 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7804 * Changed silc_command_pending list to SilcDList. Also, added
7805 `ident' field to SilcServerCommandPending structure to identify
7806 the reply and to call correct callback.
7808 Added silc_server_command_pending_check function to replace the
7809 corresnponding macro. The silc_command_pending list is not
7812 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7813 to set identifier to previously allocated Command Payload. It
7814 is used to set identifier for command when resending Command
7817 * Added silc_command_payload_encode_payload to encode Command
7818 Payload buffer from SilcCommandPayload structure.
7820 * Added silc_argument_payload_encode_payload to encode Argument
7821 payload buffer from SilcArgumentPayload structure.
7823 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7825 * Changed WHOIS command to support router connection on server side.
7826 The whois request is always sent to router unless the server is
7827 standalone server. After server has received the reply from the
7828 router will it send the reply to the client.
7830 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7831 broadcast received broadcast packet. The function is used only
7832 by router. The broadcast packet is always sent to the router's
7835 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7836 render given ID to printable string, for log files for example.
7838 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7840 * Made basic router to router connections working. At least they
7841 can now connect to each other but nothing really works the way
7842 they are supposed - yet.
7844 * Added new initiator token to RouterConnection configuration
7845 file in silcd/serverconfig.[ch]. It is used to tell whether we
7846 are the initiator to the remote router or whether we'll expect
7847 the other end to connect.
7849 * Moved registering of listener task to silc_server_init, hence
7850 the server starts listenning as soon as it is run, even if it
7851 does not have connections to other routers. Let's see how well
7854 * Changed default connection retry timeouts for more suitable in
7857 * Removed cipher and such arguments from silc_idlist_add_client
7858 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7859 Added new function silc_idlist_add_data to add the keys and stuff
7862 * Added SilcIDListData structure and added it to SilcClientEntry
7863 and SilcServerEntry as their first field in the structure. This
7864 way we can explicitly cast the ID entries to the SilcIDListData
7865 structure and get common data for the entries. In past, we had
7866 to first check what type of connection it is and then cast it to
7867 correct ID entry type. Now, we can directly cast the opaque
7868 pointer to the SilcIDListData (no matter what ID entry it actually
7869 is) and get the data needed.
7871 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7873 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7874 in some circumstances even if threre were timeout tasks, though not
7875 IO tasks, but tasks anyway. Now fixed.
7877 * Defined SilcServerConnection structure to hold connection specific
7878 stuff about directly connected servers and routers. The definition
7879 is currently in silcd/server_internal.h. I thought about having
7880 a bit more important role fro this struct but for now it is used
7881 only when connecting to other server (or router actually).
7883 * Added connecting retry support in server when connecting to
7884 router(s). The retry feature implement exponential backoff
7885 algorithm. Also, added SilcServerParams structure to hold default
7886 parameters for server. For now, it include these retry settings
7887 and are hard coded. After server is moded to be as Silc Server
7888 Library this structure will be more important.
7890 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7892 * Changed client librarys channel->clients table to SilcList and
7893 changed code accordingly.
7895 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7897 * Changed client's channel table to SilcList and changed code
7898 accordingly. Also changed SilcChannelClientEntry to include back-
7899 pointer to the channel so that client entry can use that structure
7900 as list as well and we have fast cross-reference to the channel.
7901 This change dramatically decreased the complexity of channel
7902 handling with client entry and vice versa (removed one extra
7903 loop when searching for channel entry from many functions).
7905 * Changed server->sim from table to SilcDList and changed code
7908 * NAMES command can now be used from user interface. It will show
7909 the user list on the channel, neatly.
7911 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7912 Code now saves realname of the user if it becomes available.
7914 * Renamed configure.in to configure.in.pre and made ./prepare
7915 script to automatically add correct version string to
7916 configure.in which it creates from configure.in.pre.
7918 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7920 * NAMES command reply now shows users mode with the nickname when
7923 * Moved silc_client_ch[u]mode[_char] functions from
7924 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7925 place sucks, they are utility functions and should be in some
7928 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7930 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7933 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7937 * Added TRQ (efficient deque and list library) into lib/trq. This is
7938 a very good list library that is currently used in the SILC. Defined
7939 SilcList API over the library because I didn't like the API very
7940 much. See lib/trq/silclist.h for the API and examples of how to
7941 use the API. Fixed various places in the code to use the new
7942 SilcList API. The SilcList is meant for lists that has a structure
7943 already defined as a list. It is not suitable to add just some
7944 context to the list (in TRQ, the context is the list actually).
7946 So, I defined SilcDList that can be used for the purpose where
7947 predefined list structure does not exit. This can be used as
7948 such list. Now some context just can be added to the SilcDList.
7949 Currently this list is not used in the SILC just yet, though there
7950 are a lot places where this can replace dynamically allocated
7951 tables and I will fix these places, later, to use SilcDList.
7952 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7953 and use TRQ internally).
7955 Also fixed some annoying warning messages that the original TRQ
7956 code generated. Also minor changes to TRQ's Makefile.in.
7958 * Added support for querying by Client ID to both WHOIS and
7959 IDENTIFY commands into server, as required by the protocol.
7961 * Removed method function pointers from SilcBuffer structure. They
7962 weren't used to anything and just increased the context size for
7963 no good reason. This change also made silc_buffer_alloc and
7964 silc_buffer_free functions inline functions.
7966 * Disabled command flooding detection support until it's fixed so
7967 that it accepts commands in but does not execute them more than once
7970 * Added silc_net_localhost(), to return local hostname, into
7971 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7972 that must be initialized before calling silc_client_init.
7974 * Added new function: silc_server_send_notify_on_channels to send
7975 notify messages to all channels client has joined. It is assured
7976 that the message is sent only once per client.
7978 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7979 lib/silcutil/silcutil.[ch] as silc_format function. The new
7980 function is generic and is used by server as well, not only by
7981 the logging routines.
7983 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7984 the provided version string was not acceptable. Added new function:
7985 silc_ske_check_version into lib/silcske/silcske.h. The function
7986 must be implemented by the application (client or server) and it
7987 does not reside in the SKE library. The function checks the version
7988 string remote end sent.
7990 * Added back pointers (to opaque context and to SilcSocketConnection)
7991 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7993 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7994 duplicate packet context structure.
7996 * Changed `notify' client operation to send same arguments as client
7997 receives from server except for ID's. ID's are mapped to correct
7998 ID entry and that is returned. Also, if channel entry is not sent
7999 by server but the notify is for channel the channel entry is sent
8000 to application (otherwise application doesn't know that it is for
8001 channel (library gets it from packet's Destination ID)).
8003 * Added silc_client_remove_from_channels into client library to
8004 remove a client from all channels it has joined to. Used when
8005 received SIGNOFF notify from server. Added also new function
8006 silc_client_replace_from_channels to replace old ID entry with
8007 new ID entry on all channels. Used when received NICK_CHANGE
8010 * Fixed ID Cache list handling in silc_idlist_get_client in
8011 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
8012 to get (or query) client by ID.
8014 * Updated TODO list.
8016 * Added connection authentication status message defined by the
8017 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
8018 support for these into the code in client and server side.
8020 * Added generic function silc_client_send_command to send any command
8021 with variable argument list. Application should use this function
8022 to send commands if the command functions provided by the library
8023 does not suite for the application's user interface needs.
8025 * Added new `failure' client operation. Application is notified about
8026 received failure packet if client is executing a protocol. In this
8027 case the protocol's execution has failed.
8029 * Added SKE's end notify to send the SKE_SUCCESS notify message that
8030 is required by the protocol.
8032 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
8033 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
8036 * Added status flag to SilcSKE object to indicate realtime status
8037 of the SKE protocol.
8039 * Application receives now exactly same command reply arguments as
8040 the library receives from server. However, if ID is received the
8041 corresponding ID entry is returned to the application (eg. Client
8042 ID is mapped to correct SilcClientEntry entry and that is returned).
8043 Changed command_reply client operation due to this change.
8045 * Changed all ID's in commands and in command replys as ID Payloads.
8046 Change affected both client and server side codes.
8048 All ID's sent in SILC network (with execption of ID's in SILC
8049 Packet header) are sent in ID Payload to support variable length
8052 * Server now notifies nick changes and notifies all clients on
8053 the channels about the new nickname (about the new Client ID,
8056 * Implemented CMODE command to change channel modes. Supports all
8057 channel modes defined by the protocol specs except ban and invite
8058 lists. (Also, private channel key mode is supported but support for
8059 setting private channel key in client is missing, thus, this mode
8060 has no effect on client side (except that server requires that the
8061 client uses private channel key and normal channel traffic does not
8064 Also, invite mode works per se, but INVITE command does not work
8065 yet correctly, so you can set channel as invite only channel but
8066 inviting clients to the channel does not work (it is yet to be
8067 thought what's the best way to do it).
8069 * Added new command SILC_COMMAND_CUMODE to change user mode on the
8070 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
8071 Implemented CUMODE command to change user's mode on the channel.
8072 Supports all modes defined by the protocol specs.
8074 * Added NAMES command reply to return users modes on the channel.
8076 * Removed unnecessary and slow ciphers from lib/silccrypt.
8078 * Set SO_KEEPALIVE option to connection sockets by default.
8080 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
8082 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
8083 redefined the Notify Payload into protocol specs.
8085 * Added silc_id_payload_parse_id to get ID directly from raw
8088 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8090 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
8091 accept searching by Client ID as well.
8093 * Added support for LEAVE and SIGNOFF notify types in client library.
8095 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
8096 to parse ID Payload from raw data.
8098 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8100 * Added flags parameter into silc_ske_assemble_security_properties
8101 function in lib/silcske/silcske.[ch].
8103 * Changed notify client operation to fit better for notify messages
8104 sent by server. The notify payload received from server is now
8105 passed to the application (after parsing it to SilcNotifyPayload).
8106 It is application's responsibility to retrieve the arguments
8107 from the payload and show the message the way it wants. The message
8108 sent by server is implementation specific.
8110 * Changed public keys to comply with the protocol specification.
8111 Old public keys are not supported anymore and are not compatible.
8113 * Removed nickname from Channel Payload as the latest draft removed
8114 it. The client must resolve the nickname from the NAMES command
8115 reply received when it joined the channel.
8117 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
8119 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8121 * Fixed some errors in protocol specification drafts.
8123 * Created lib/silccore/silcnotify.c to implement Notify Payload
8124 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
8125 generic payloads described by protocol specifications. The file
8126 includes implementations for ID Payload and Argument Payload.
8128 * Changed Command Payload implementation to use the new Argument
8129 Payload. Changed command_xxxx_payload to command_payload_xxxx
8130 to comply with SILC coding conventions.
8132 * Added suppport for Argument Payload handling in Notify Payload
8133 implementation as protocol requires it. Added the new support
8134 into server and client lib as well.
8136 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8138 * Added support for multiple nicknames on same channel. [n] is
8139 added locally to the nickname if there are more than one same
8140 nicknames on the channel.
8142 * Server now sends all nicknames that matched WHOIS request.
8143 Client also shows the list received from server.
8145 * Added TOPIC command to client side. User can now set and show
8146 current topic on channel.
8148 * Added MOTD command to client and server. Also, server sends the
8149 motd when client connects to the server.
8151 * Changed version strings to comply ISO 8601.
8153 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8155 * Fixed protocol error handling in client library. It should now
8156 cope even if the SKE fails for some reason.
8158 * Made new protocol specification drafts for submitting to IETF.
8160 * Implemented TOPIC command to server in silcd/command.c.
8162 * Added two new notify types into lib/silccore/silcnotify.h:
8163 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
8164 notify nickname change and topic setting/change on a channel.
8166 * API change of command_reply operation in client library. The
8167 application gets now the status type received from server as well.
8169 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8171 * Removed the function just added to lib/silcutil/silcschedule.[ch].
8173 * Cras fixed and optimized the packet handling even further and
8174 it should work now. Minor change to the prototype of function
8175 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
8177 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8179 * Added new function into lib/silcutil/silcschedule.[ch]:
8180 silc_schedule_with_fd to select() a specified fd. The function
8181 returns after timeout expires or data arrives or goes. The
8182 function is used by packet routines to wait that all data is
8183 received from network.
8185 * Fixed data reading from network in lib/silccore/silcpacket.c.
8186 The code now assures that all data is read from the fd and then
8187 continues packet processing. This was a bug fix since the code
8188 used to drop some data in some circumstances.
8190 * Added new function into lib/silcclient/client.[ch]:
8191 silc_client_start_key_exchange to start key exchange after
8192 connection has been established to server. The code internally
8193 now uses this funtion but its main purpose was to provide it
8194 for applications that perform their own connecting. After
8195 application has created a connection it merely calls this
8196 function to start the key exchange between client and server.
8197 The library takes care of everything else after that.
8199 Updated also lib/silcclient/README to explain the usage of
8202 * Do not send to application information that connection has
8203 been established. Application gets notified it by connect
8206 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8208 * Applied cras's patch to add silc_schedule_one function. The
8209 function runs scheduler once and returns.
8211 * Fixed the scheduler after cras messed it up. The timeout
8212 handling works now as it's supposed to work.
8214 * Added into lib/silccore/ silcnotify.h to include notify
8215 message types support. Changed silc_server_send_notify*
8216 functions, in server.[ch], to support those new notify types.
8217 Added the support for the notify types into client library,
8218 as well. Added new notify client operation into ops.h in
8221 * Changed silc_server_packet_send_to_channel to send normal
8222 packets instead of just channel message packets. The function
8223 is now used to send the notify packets to channels. It is not
8224 used to send channel message packets anymore, as server never
8227 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
8228 va_arg()s as it seems to require it nowadays. I guess, if SILC
8229 is compiled with older va_arg() the new code should work anyway.
8231 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8233 * Splitted core library. Core library (lib/silccore) includes
8234 now only SILC protocol specific core (and common) components.
8235 Created new utility library (lib/silcutil) that includes more
8236 generic purpose stuff. The stuff for util library was taken
8237 from the old core library. This was minor and easy split.
8239 * Created SILC Client Library (lib/silcclient) that includes
8240 implementation of the SILC client without user interface. This
8241 was major move from silc/ directory. The code has been changed
8242 so that it is transparent towards the user interface. The
8243 silc/ directory includes now the same user interface as before
8244 and it uses the new client library. Read lib/silcclient/README.
8245 Basicly, the client library performs everything else related
8246 to SILC except user interface handling. Also, configuration
8247 files are considered to be part of user interface and library
8248 does not handle them.
8250 This change also changed a lot of structures, function naming etc.
8251 Most important change was that SilcClientWindow object was
8252 renamed to SilcClientConnection in the client library. Created
8253 also new file lib/silcclient/ops.h. Also added new files
8254 silc/local_command.[ch] and silc/client_ops.[ch].
8256 All these changes were made to make it easier for user interface
8257 designers to create what ever user interface for the SILC client
8260 It is also expected that the server will be moved to lib
8261 directory as well and SILC Server Library will be created;
8262 sometimes in the future.
8264 * Removed Local commands from lib/silccore/silccommand.h as
8265 they are application specific and new client library does not
8266 handle any of those anymore.
8268 * Several functions moved to lib/silcutil/silcutilc.[ch] from
8269 old client implementation in silc/.
8271 * Added support for callback functions in SILC_LOG_* macros.
8272 Application can now set its own callbacks that will be called
8273 instead of using the default functions that will always print
8274 the debug messages to stderr (or stdout). Also, debugging can
8275 now be disabled by setting silc_debug to FALSE and re-enabled by
8276 setting it to TRUE. Note, that logging will still work even
8277 if debugging is disabled.
8279 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
8280 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
8281 silc_log_reset_debug_callbacks.
8283 * To enable debugging in silc client one must give now -d
8284 option on command line.
8286 * Changed silc_schedule_init to automatically allocate task queues
8287 if they are not allocated before calling it.
8289 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8291 * Added GMP 3.1 into math library.
8293 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8295 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
8296 a channel in SILC network. The packet is used by servers and
8297 routers to notify other routers that user has left a channel.
8298 This little feature was missing until now. Added the feature
8299 to protocol specification as well.
8301 Added functions: silc_server_send_remove_channel_user and
8302 silc_server_remove_channel_user into server.[ch].
8304 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
8305 lib/silccore/silcpacket.h. However, they are not implemented
8308 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8310 * Fixed joining to a channel and sending channel messages
8311 between server and router. The channel message sending should
8312 now work inside a cell.
8314 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8316 * Fixed the private message sending between server and router.
8317 The private message sending should now work inside a cell.
8319 * Added silc_server_replace_id into server.[ch] to replace
8320 existing ID in the SILC network.
8322 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
8323 and silc_idlist_replace_server_id into idlist.[ch] in server.
8325 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8327 * Fixed the server to server connections. Server can again now
8328 connect to router. Router to router connections probably does
8331 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8333 * Added dynamic protocol registering support. Now protocols can
8334 registered and unregistered on the fly. Patch by cras.
8336 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8338 * Added lib/contrib directory to hold routines that some platforms
8339 don't have but are needed by SILC.
8341 * Added getopt.c, getopt1.c and getopt.h from GNU C library
8342 into lin/contrib to provide getopt() and getopt_long() for
8343 those who don't have it.
8345 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8347 * Added AWAY command to client. When away message is set and
8348 client receives a private message packet the client automatically
8349 replies to the sender with the away message.
8351 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
8352 bug seemed to be the cause of recent problems when compiling
8355 * Added version detection support to SKE protocol specification
8356 and added the new changes to the SKE implementation as well.
8357 There were other minor changes in the SKE protocol as well.
8359 Many changes in lib/silcske/silcske.[ch] and in
8360 lib/silcske/payload.[ch].
8362 * Added ^U functionality, clear input line. Patch from cras.
8364 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8366 * Mainly small bugfixes on core library. Fixed some debugging
8367 logging and buffer overflow in silclog.c.
8369 * Updated config.sub and config.guess on the distribution tree.
8371 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8373 * Added command lagging support in server. Client may execute
8374 commands now only once in two seconds.
8376 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8378 * Optimized packet reception. MAC computation and checking is now
8379 also more optimized. A lot previously duplicated code is now
8380 used as generic by both client and server.
8382 * Fixed key pair generation in clientutil.c
8384 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8386 * Added into lib/silccore/silcbufutil.[ch] new function;
8387 silc_buffer_realloc.
8389 * Moved generic packet sending/encryption functions to
8390 lib/silccore/silcpacket.[ch] from client and server. Some
8391 rewriting of the functions.
8393 * Moved all generic packet reception/decryption functions to
8394 lib/silccore/silcpacket.[ch] from client and server. The
8395 packet processing is now much cleaner in both client and server.
8396 These were major changes in both client and server.
8398 * Created many common functions in server to do packet sending.
8399 Previously code were duplicated a lot, this has been removed
8402 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8404 * Rewrote major parts of the ID cache system. Don't know
8405 whether it is better now or not but at least the API is more
8408 * Major rewrite on ID cache stuff on client because of the ID
8409 cache API changes. Added idlist.c to client.
8411 * Also major rewrite on ID cache stuff on server as well.
8412 Major rewrite of idlist.[ch]. SilcXXXList's are now named
8413 SilcXXXEntry's. We won't keep anymore idlist specific pointers
8414 in hand, instead they are all put into the ID cache system now.
8415 All server_idlist_* routines uses ID cache now instead of
8416 traversing its own lists (those lists does not exist anymore).
8417 SilcIDList though still exists. Also, SilcXXXEntry's are
8420 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8422 * Finally made the SKE implementation compliant to the protocol
8423 specification. All mp integers are now binary encoded as
8424 opposed being HEX encoded.
8426 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
8429 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
8430 functions: silc_[encode/decode]_pem. Also added function
8431 silc_encode_pem_file to PEM encode with newlines ('\n') for
8434 * SILC public keys are now encoded either PEM or binary. Same
8435 option is for private keys as well. By default private keys
8436 are binary encoded and public keys PEM encoded. Silly HEX
8437 encoding were removed.
8439 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
8440 function to create fingerprints.
8442 * Fixed a bug in SHA1; does not change the original data anymore.
8444 * Partly implemented INFO command on client and server side.
8445 Fixed CLEAR command. Changes to SERVER command; show current
8446 server(s) when giving command without arguments. Added
8447 VERSION command to client.
8449 * Added check to server that unregistered connections cannot
8450 execute commands (unless it is specificly allowed).
8452 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8454 * Fixed screen refresh.
8456 * Fixed channel joining bug from client. On some circumstances
8457 client tried to join to a channel it had already joined.
8459 * Added public key verification process into client's protocol.c.
8460 The client now verifies the public key from user and saves
8461 it into ~./silc/serverkeys/ directory.
8463 Added into: clientutil.[ch]: silc_client_verify_server_key.
8465 * Changed SKE protocol's silc_ske_initiator_finish function
8466 to accept callback function that verifies the received public
8467 key. Removed old silc_ske_verify_public_key function.
8469 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8471 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
8472 silc_pkcs_private_key[_data]_set.
8474 * Made the password and public authentication more cleaner in
8475 server's protocol.c.
8477 * Removed historic and obsolete protocol `channel_auth' from
8478 both client and server.
8480 * Removed wrong way of sending command status messages from
8481 server to client in server's command.c. The old way violated
8482 protocol specification.
8484 Changes to silccore/silccommand.[ch]: removed
8485 silc_command_encode_status_payload -> not needed anymore,
8486 changed silc_command_encode_payload_va to accept extra
8487 argument on variable argument list. The argument type must
8488 now be provided to the function. Also, added new function:
8489 silc_command_encode_reply_payload_va which is same as
8490 normal command_encode_payload_va except command status type
8491 is provided as extra argument.
8493 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8495 * Added ~./silc directory handling. The directory includes the
8496 public and private keys for the client.
8498 Added silc_client_check_silc_dir, silc_client_create_identifier
8499 and silc_client_load_keys.
8501 * Implemented SILC protocol compliant public key. Added public
8502 and private key saving to and loading from files.
8504 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
