511 command_reply client operation. Affected file is
512 lib/silcclient/command_reply.c.
514 * Changed the channel message payload's MAC generation to
515 include the IV in the MAC as well. This way all relevant
516 parts of the channel message payload are authenticated also
517 with the channel message MAC (and not only by packet MAC).
518 Causes incompatibility with 1.0 protocol. Protocol TODO #7.
519 Affected file is lib/silccore/silcchannel.c.
521 * Fixed the SKE to save the remote version, since the
522 silc_ske_parse_version mistakenly checked wrong version,
523 after it replaced the start payload. Affected files are
524 lib/silcske/silcske.[ch].
526 Fri Apr 5 16:03:03 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
528 * Splitted lib/silcutil/silcutil.h into silcstrutil.h for

530 silc_utf8_[encode/decode/valid] for UTF-8 string encoding.
531 Affected files lib/silcutil/silcstrutil.[ch].
533 * Renamed silc_*_pem functions to silc_pem_* functions. Affected
534 files are lib/silcutil/silcstrutil.[ch].
536 * Defined that the security property fields in SKE SHOULD be
537 UTF-8 encoded, defined that version string MUST be US-ASCII
538 encoded, defined that passphrases sent in connection
539 authentication protocol MUST be UTF-8 encoded. Implemented
540 these to the client and server. Defined also that other
541 passphrases sent in the protocol MUST be UTF-8 encoded.
542 Affected files are lib/silcske/silcske.c,
543 lib/silcclient/protocol.c, silcd/protocol.c,
544 silcd/serverconfig.c, and lib/silccore/silcauth.c.
546 * Changed the silc_client_close_connection interface to not
547 need the SilcSocketConnection which should not be visible
548 to application. Affected files are lib/silcclient/client.c
549 and lib/silcclient/silcclient.h.
551 * Rewrote the text for Private Message Key Payload in the
552 protocol specification. Protocol TODO #11.
554 Wed Apr 3 16:24:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
556 * Upgraded the protocol version to 1.1, updated protocol specs
559 * Added the nickname as new argument to NICK_CHANGE notify and
560 added it to protocol specs and implemented it to client and
561 server. Protocol TODO #3. Affected files are silcd/idlist.[ch],
562 silcd/command.c, silcd/packet_receive.c, packet_send.[ch], and
563 lib/silcclient/client_notify.c.

571 the `notify' client operation.
573 * Fixed the Max Argument fields that had too large value set
574 in the protocol specs. Protocol TODO #14.
576 * Added the LEAVE command reply to return the ID of parted
577 channel. Updated protocol specs and implemented it to the
578 client and server. Protocol TODO #15. Affected files are
579 silcd/command.c, lib/silcclient/command_reply.c. The channel
580 entry is now returned to application in the `command_reply'
583 * Rewrote the version SKE version checking in client libary
584 and in server to use the silc_parse_version_string. Affected
585 files are lib/silcclient/protocol.c, silcd/protocol.c.
587 * Added SILC_STATUS_ERR_NO_CHANNEL_FOPRIV error status to few
588 commands that was missing it, and updated protocol specs and
589 the server implementation. Protocol TODO #10. The affected
590 file is silcd/command.c.
592 * Defined new message flags SILC_MESSAGE_FLAG_REPLY to be
593 generic reply to a generic request (REQUEST flag), and
594 SILC_MESSAGE_FLAG_DATA to send any kind of data in a generic
595 way. A draft-riikonen-silc-flags-payloads-00.txt is written
596 to define the payload for DATA flag. Added the flags to
597 the implementation. Protocol TODO #9. Affected file is
598 lib/silccore/silcchannel.h.
600 Changed the client library to return the message length
601 to application as well in the channel_message and private_message
602 client operations. Affected files are
603 lib/silcclient/client_prvmsg, lib/silcclient/client_channel.c,
604 lib/silcclient/silcclient.h, irssi/src/silc/core/client_ops.c,
605 and lib/silcclient/client_ops_example.c.
607 * Added two new channel modes: SILC_CMODE_SILENCE_USERS
608 and SILC_CMODE_SILENCE_OPERS which can be used to moderate
609 the channel. Updated protocol specs and impelemented this
610 to client and server. Protocol TODO #6. Affected files are
611 silcd/packet_receive.c, server_util.c, lib/silcclient/command.c,
612 lib/silcclient/client_channel.c, lib/silccore/silcmode.h.
614 Added new options m and M to CMODE command in Irssi SILC
615 client to set these modes.
617 * Deprecated all administrative commands from SILC protocol
618 since they are highly implementation specific commands.
619 Updated protocol specs. Moved the old commands in
620 implementations to private range of command types. Affected
621 files are silcd/command.c, lib/silcclient/command.c and
622 lib/silcclient/command_reply.c. Protocol TODO #8.
624 * Fixed a bug in server where sending unknown command crashes
625 the server. Affected file silcd/command.c.
627 Wed Apr 3 09:57:47 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
629 * Added SILC_PROTOCOLVERSION macro to check protocol version
630 of a socket connection. The affected file is
631 lib/silcutil/silcsockconn.h.
633 * Added better error logging in rekey protocol. Affected file

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

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

912 silc_server_check_cmode_rights to server_util.[ch].
913 Affected files are silcd/server_util.[ch], silcd/command.c.
915 * Added function silc_server_check_umode_rights to check whether
916 changing client's user mode is allowed. Added check for
917 UMODE_CHANGE notify type that the umode change is allowed
918 by the client. Affected files are silcd/server_util.[ch],
919 silcd/packet_receive.c and silcd/command.c.
921 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
923 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
924 ID length. It ignored that ID can be IPv6 based as well.
925 Affected file lib/silccore/silcpacket.h.
927 * Fixed the silc_id_id2str and silc_id_str2id to take the
928 IPv6 address offset's into consideration. Affecte file is
929 lib/silccore/silcid.c.
931 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
933 * Fixed the internal Unix scheduler functions to check for
934 NULL context they may receive. The affected file is
935 lib/silcutil/unix/silcunixschedule.c.
937 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
939 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
940 can specify different directory with --home command line
941 parameter. Affected files irssi/src/silc/core/client_ops.c,
944 * SILC-specific commands aren't now executed if the active server
945 isn't of SILC-type, so there won't be problems with having
946 IRC and SILC protocol support in same client. Affected files
947 irssi/src/silc/core/silc-channels.c, silc-servers.c,
950 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
952 * Improved the signal support in SILC Schedule. Added new
953 function silc_schedule_signal_call which is used by application
954 to mark a signal to be called. It is now safe to perform
955 any kind of tasks in signal callbacks since it is guaranteed
956 that the application specified signal callback is called
957 after the signal is over. Affected files are
958 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
960 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
962 * Added `name' field to SilcChannelPrivateKey to represent
963 application given name for the key. Moved also the context from
964 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
965 Added the `name' argument also to the function
966 silc_client_add_channel_private_key.
968 Added function silc_client_current_channel_private_key to set the
969 current channel private key in use.
971 Added "change" command to KEY command which can be used to change
972 the current channel private key. Bound the command also to
975 Also affected files lib/silcclient/client_channel.c,
976 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
978 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
980 * Added silc_rng_get_byte_fast function in to the
981 lib/silccrypt/silcrng.[ch].
983 * Changed the interface of silc_packet_assemble and the
984 silc_packet_send_prepare. If silc_packet_assmble is now
985 called the application does not call silc_packet_send_prepare
986 because the library will call it automatically. These
987 interfaces now also return a reference to the outgoing buffer
988 which includes the assembled packet, which the application can
989 use to encrypt the packet.
991 Affected files are lib/silccore/silcpacket.[ch],
992 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
993 silcd/packet_send.c, server_backup.c and packet_receive.c.
995 * Fixed a packet sending bug on very high load, where outgoing
996 packet queue wasn't handled correctly and packets got corrupted.
997 Affected files are lib/silcutil/*/silc*sockconn.c,
998 lib/silcclient/client.c and silcd/server.c.
1000 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1002 * Added macro SILC_PACKET_DATALEN which can be used during
1003 packet assembling to check whether the data to be added to
1004 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
1005 len is truncated until it fits it.
1007 Added checks for maximum length of channel message payload and
1008 private message payload also.
1010 Added checks for maximum packet length in server and in
1013 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
1014 lib/silcclient/client.c, lib/silccore/silcchannel.c and
1015 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
1016 lib/silcclient/client_prvmsg.c.
1018 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1020 * Added silc_server_packet_queue_purge call to the
1021 silc_server_disconnect_remote to assure that all data in the
1022 queue before disconnecting is sent to the network. Affected
1023 file silcd/server.c.
1025 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1027 * Added the deleting of server's own ID cache entry to the
1028 silc_server_free function. Free also everything else that
1029 has been allocated in silc_server_init. The affected file
1032 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1034 * Added functions silc_parse_version_string, silc_version_to_num,
1035 and silc_ske_parse_version to parse SILC protocol style version
1036 strings. Affected files lib/silcutil/silcutil.[ch] and
1037 lib/silcske/silcske.[ch].
1039 * Added new configuration params: version_protocol, version_software
1040 and version_software_vendor to specify what version the remote
1041 host must at least be to be able to connect to server. The vendor
1042 string can be regex matched too. Added new function
1043 silc_server_connection_allowed to check maximum number of allowed
1044 connections, and allowed versions for incoming connections.
1045 Affected files are silcd/server.c, server_util.[ch] and
1048 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1050 * Added preliminary support for signals in scheduler. The
1051 signals we care about are now blocked always when the scheduler
1052 is locked. This way we can synchronise the use of signal with
1053 scheduler. It is guaranteed that when signal occurs the scheduler
1054 is not locked, and thus new tasks can be safely added to the
1057 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
1058 to silc_schedule_internal_init and silc_schedule_internal_uninit.
1059 Added new platform specific routines
1060 silc_schedule_internal_signals_[un]block and
1061 silc_schedule_internal_signal_[un]register.
1063 Added new functions to SILC Schedule API:
1064 silc_schedule_signal_[un]register. Each signal that application
1065 is going to use should be registered to the scheduler.
1067 Affected files are lib/silcutil/silcschedule.[ch],
1068 lib/silcutil/*/silc*schedule.c.
1070 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1072 * Check for unauthenticated client and server in the
1073 silc_server_new_client and silc_server_new_server functions.
1074 Affected file silcd/packet_receive.c.
1076 * Added function silc_string_is_ascii to check whether given
1077 string is 7-bit ASCII string. Affected files are
1078 lib/silcutil/silcutil.[ch].
1080 * Added function silc_id_is_valid_server_id into the
1081 silcd/serverid.c and added checking for valid Server ID's in
1082 silc_server_new_server. The Server ID must always be based
1083 on the server's public IP address.
1085 * Added logging of DISCONNECT packet message in the server.
1086 Affected file silcd/server.c.
1088 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1090 * Changed all library interfaces that use Global RNG to also
1091 accept SilcRng as argument. Affected files are
1092 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
1093 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
1094 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
1095 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
1096 lib/silccrypt/rsa.c.
1098 * Added function silc_pkcs_generate_key to the
1099 lib/silccrypt/silcpkcs.[ch] for applications so that they
1100 don't need to do pkcs->pkcs->init calls anymore.
1102 * Remove SilcSocketConnection from the SFTP API since it really
1103 wasn't needed there. The application has the information
1104 saved in its contexts anyway and the SFTP layer doesn't need
1105 know about it. Affected files lib/silcsft/silcsftp.h and
1106 lib/silcsftp/sftp_[server/client].c.
1108 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
1109 The SilcSimContext is not SilcSim.
1111 * Fixed possible buffer overflows in silc_id_render in the
1112 lib/silcutil/silcutil.c.
1114 * On EPOC the global crypto module lists are not used at all
1115 in the crypto library. Added support for using the constant
1116 algorithm list on EPOC. Affected files are
1117 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
1120 * Fixed the handling of third parameter of KICKED notify, since
1121 it was mistakenly updated to SILC Protocol 1.0 even though it
1122 is to be included in 1.1. Since it is not in 1.0 it is not
1123 mandatory, and this fix now handles it only if it is provided,
1124 and it is not error if it is not provided. Affected file
1125 lib/silcclient/client_notify.c.
1127 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1129 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
1130 client. Affected file irssi/src/silc/core/client_ops.c.
1132 * Merged with Irssi 0.8.4 from irssi.org CVS.
1134 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1136 * Check for valid socket connection in client entries before
1137 sending any messages. Fixes a crash, but doesn't fix some
1138 other underlaying bug that is lurking there. Affected
1139 file silcd/packet_send.c.
1141 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
1143 * $usermode, $cumode and $cumode_space expandos shouldn't do
1144 anything with non-SILC server records. Affected file
1145 irssi/src/silc/core/silc-expandos.c
1147 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1149 * Fixed the silc_net_check_[host/local]_by_sock to support
1150 IPv6 bound sockets as well. Now they can return IPv6 addresses
1151 as well. Affected file lib/silcutil/silcnet.c.
1153 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
1154 Affected lib/silcutil/unix/silcunixnet.c.
1156 * Fixed ID rendering (at least on some platforms, not NetBSD)
1157 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
1159 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1161 * Added silc_hash_public_key and silc_hash_public_key_compare
1162 functions to be used with SilcHashTable. They can be used to
1163 hash public keys and compare public keys in hash table. Affected
1164 file lib/silcutil/silcutil.[ch].
1166 * Added support for specifying multiple public keys for Client
1167 connection section in server configuration file. This makes it
1168 possible to accept multiple public keys from same host, or to
1169 make a section that accepts any incoming host, and have the
1170 accepted public keys listed in the section.
1172 Added functions silc_sever_[find/get]_public_key, added the
1173 support for this actually to all connection sections but only
1174 the Client section is currently allowed to specify multiple
1177 Affected files are silcd/server.c, server_internal.h,
1178 command.c, protocol.c, server_util.[ch], packet_receive.c.
1180 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1182 * Merged Irssi 0.8.2 from irssi.org CVS.
1184 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1186 * If silc_debug is TRUE, also output standard logging messages
1187 to stderr with the debug output.
1189 Made silc_log_reset_all() flushing all channels before returning.
1190 Also fixed some documentation typos.
1192 Affected files are lib/silcutil/silclog.[ch].
1194 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1196 * Fixed the server to check correctly the amount of connections
1197 from single host, by checking also the type of the connection.
1198 Fixed also the comparison of number of connections and number
1199 of allowed connections. Affected files are silcd/server.c,
1202 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1204 * Fixed the USERS command reply to save the user's mode on the
1205 channel as well. Fixed JOIN command reply to check whether a
1206 client is on channel already and not join it twice. Affected
1207 file lib/silcclient/command_reply.c.
1209 * Added new file silc-expandos.c into irssi/silc/core/ to return
1210 various stuff for various signal for the statusbar etc. updating.
1211 Now Irssi SILC client prints channel user modes etc. on the
1214 * The user mode (like server/router operator changes) is now shown
1215 on the Irssi SILC client's statusbar. The affected files are
1216 irssi/src/silc/core/client_ops.c, silc-expandos.c.
1218 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1220 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
1221 to SILC_SCHEDULE_[UN]LOCK macros.
1223 * Added more error printing to logs in server code. Affected
1224 files silcd/server.c and silcd/protocol.c.
1226 * Fixed -S option parsing in Irssi SILC Client. Affected file
1227 irssi/src/silc/core/silc-core.c.
1229 * Added silc_buffer_alloc_size function. Affected file is

1254 * Changed all integer type names:
1255 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
1256 to avoid collisions with other libraries using same type names
1259 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1261 * Added `prefer_ipv6' argument to the functions
1262 silc_net_gethostbyname[_async]. If it is TRUE it will return
1263 IPv6 address over IPv4. If FALSE IPv4 address is returned
1264 even if IPv6 address was found. Affected files
1265 lib/silcutil/silcnet.[ch].
1267 * Added support silc_net_create_connection[_async] to fallback
1268 to IPv4 address if IPv6 address could not be used (like if
1269 it doesn't work on a specific system). Affected file in
1270 lib/silcutil/unix/silcunixnet.c.
1272 Sat Feb 23 15:20:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1274 * Added silc_schedule_reinit function to do the enlarging
1275 of the max tasks handling capabilities of the scheduler.
1276 Affected files lib/silcutil/silcschedule.[ch].
1278 Wed Feb 20 20:41:01 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1280 * Added automatic extern "C" { ... } for C++ compilers so the
1281 application does not need to define them. Affected file
1282 includes/silcincludes.h.
1284 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
1285 old name went against naming convention. Applications now
1286 include "silcclient.h" instead of "clientlibincludes.h".
1287 Removed includes/clientlibincludes.h, it is redundant now.
1289 * Renamed includes/version.h to silcversion.h.
1291 * Added really preliminary support for OS/2 into the util
1292 library. Only thread & mutex API is implemented, others
1293 are still to be implemented. Created the lib/silcutil/os2/
1294 directory. Created also file includes/silcos2.h.
1296 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1299 Created lib/silcutil/beos/, and implemented all the needed
1300 functions to support SILC on BeOS. Created also file
1301 includes/silcbeos.h.
1303 Mon Feb 18 15:49:22 EET 2002 Timo Sirainen <tss@iki.fi>
1305 * Added proper initializations to silc's irssi code, so it's
1306 now possible to load it as module. Affected files
1307 irssi/src/silc/core/silc-core.c,
1308 fe-common/silc/fe-common-silc-core.[ch] and fe-text/silc.c

1327 * Added `user_count' to the SilcChannelEntry which now tells the
1328 number of users on the channel. The user count is now saved
1329 in normal server of global channels as well. Affected files
1330 silcd/server.c, idlist.h, packet_receive.c and command.c.
1332 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
1333 include file utility functions.
1335 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
1336 instead of calling directly OS routines.
1338 * Fixed NICK change printing in Irssi SILC Client. Fixed
1339 KICKED notify printing in Irssi SILC Client. Affected file
1340 irssi/src/silc/core/client_ops.c.
1342 * Fixed a NICK change bug in client library, to not recreate the
1343 client_entry->channels hash table everytime nick is changed.
1344 Affected file lib/silcclient/client.c.
1346 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1348 * ROBOdoc documented the lib/silcske/silcske.h, and improved
1349 the SKE interface a bit.
1351 * Fixed padding problem in PKCS#1. The padding was not actually
1352 random since the random number generator was used incorrectly.
1353 This security bug affects only when encrypting with PKCS#1, and
1354 it is not currently used at all in SILC. SILC only use signing
1355 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
1357 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1360 the events as signals. Fixes problems with Perl support.
1361 Affected files irssi/src/silc/core/client_ops.c, silc-channels.c.
1363 * Send the auto-nicking NICK command in client library with
1364 little timeout after connecting. The affected file is
1365 lib/silcclient/client.c.

1368 channel_rekey_secs, key_exchange_rekey, key_exchange_pfs,
1369 key_exchange_timeout, conn_auth_timeout, connections_max,
1372 Implemented all the new config settings handling in the server.
1374 Optimized the use of SKE Mutual flag usage. Use it only
1375 if connection authentication protocol is not based in public
1378 Renamed all SilcServerConfigSection* to SilcServerConfig*
1379 to have a bit shorter names.
1381 Affected files silcd/serverconfig.[ch], server.[ch], and

1415 is now done in silc_core_init() which also fixes autoconnecting
1418 Affected files irssi/src/silc/core/silc-core.c,
1419 irssi/src/fe-text/silc.c.
1421 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1423 * Added new configuration options and blocks:
1424 keepalive_secs, reconnect_count, reconnect_interval,
1425 reconnect_interval_max, reconnect_keep_trying and
1426 require_reverser_lookup. Added ConnectionParam block, and
1427 implemented the connection parameters when connecting as
1428 initiator and when accepting connections as responder.
1430 Added CONFIG_IS_DOUBLE macro in config file parsing, to check
1431 whether given configuration value has been given already.
1433 Affected files silcd/serverconfig.[c], server.[c].
1435 * Splitted the doc/example_silcd.conf.in. Separated the crypto
1436 algorithm parts and created new file silcalgs.conf, that
1437 is now included from the example_silcd.conf.in.
1439 * Optimized the silc_server_connect_to_router_second to take
1440 the connection configuration object from the SilcServerConnection
1441 object instead of finding it during the connecting phase.
1442 Added the configuration object to SilcServerConnection struct.
1443 Affected files silcd/server_internal.h, server.c.
1445 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1447 * Add the client on channel after it was resolved at the
1448 channel message receiving, and it was not already on the
1449 channel. Affected file lib/silcclient/client_channel.c.
1451 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1453 * Fixed the public key authentication to allocate always the
1454 destination signature buffer instead of using static buffer.
1455 Affected file silcd/protocol.c.
1457 Wed Feb 13 20:51:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1466 config file, allowing both public key and passphrase based
1467 authentication to be set at the same time.
1469 Added `prefer_passphrase_auth' setting in config file which
1470 can be used to set to prefer passwd auth if both passwd and
1471 public key is set. If not set, public key is preferred.
1472 This has effect only when being initiator (responder will try
1475 Added support for authentication with passphrase and public key
1476 at the same time. The passphrase is tried first always since
1477 it is faster to check.
1479 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
1481 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

1527 * Fixed the file transfer's key agreement payload to include
1528 zero port also if the hostname is NULL because it could not
1531 Call file transfer monitor callback now also if error occurs
1532 during key agreement protocol.
1534 Changed the silc_client_file_send interface to return the
1535 SilcClientFileError instead of session id. The session ID
1536 is returned into pointer provided as argument.
1538 Check that the file exists locally before sending the
1539 file transfer request at all.
1541 Affected file lib/silcclient/client_ftp.c, silcapi.h.
1543 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer
1544 error than can occur while key agreement protocol. Affected

1553 file lib/silcutil/silclog.c.
1555 * Fixed the channel message payload decryption in the function
1556 silc_channel_message_payload_decrypt to not modify the original
1557 buffer before it is verified that the message decrypted
1558 correctly. Otherwise, next time it is called with correct
1559 channel key it won't encrypt since the payload is corrupted.
1560 Affected file lib/silccore/silcchannel.c.
1562 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1564 * Do not constantly resize the window. A fix patch by cras.
1565 Affected file irssi/src/fe-text/screen.c.
1567 Sat Feb 2 16:54:18 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1569 * Applied IPv6 fix patch from Jun-ichiro itojun Hagino.
1570 Affected file lib/silcutil/silcnet.c.
1572 Fri Feb 1 22:33:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1574 * Fixed a bug in hash table internal routine for traversing
1575 the table with foreach callback. The current entry may
1576 become invalid in the callback but it was referenced after
1577 the callback returned.
1579 Do not allow auto rehashing of hash table during the
1580 silc_hash_table_foreach operation, for same reasons as it is
1581 not allowed for SilcHashTableList. Affected files are
1582 lib/silcutil/silchashtable.[ch].
1584 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1586 * Defined DLLAPI into silcincludes.h and silcwin32.h for
1587 Win32 DLL. extern's in header files are now declared with
1590 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1592 * Fixed private message handling. It used some old code that
1593 caused the client to crash. Affecte file is
1594 lib/silcclient/client_prvmsg.c.
1596 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1598 * Added function silc_client_add_channel,
1599 silc_client_replace_channel_id, and removed functions
1600 silc_client_new_channel_id and silc_idlist_get_channel_by_id
1601 from client library.
1603 * Added cross reference of the joined channels to the
1604 SilcClientEntry, and changed the SilcChannelEntry's
1605 users list to SilcHashTable. The affected files are
1606 lib/silcclient/idlist.[ch].
1608 * Fixed a bug in hash table tarversing. While the hash table
1609 is traversed with SilcHashTableList the table must not be
1610 rehashed. It is now guaranteed that auto rehashable tables
1611 are not rehashed while tarversing the list. Also defined that
1612 silc_hash_table_rehash must not be called while tarversing
1613 the table. Added function silc_hash_table_list_reset that must
1614 be called after the tarversing is over. The affected files are
1615 lib/silcutil/silchashtable.[ch].
1617 * Changed all hash table traversing to call the new
1618 silc_hash_table_list_reset in server and in client library.
1620 * Added function silc_client_on_channel to return the
1621 SilcChannelUser entry if the specified client entry is joined
1622 on the specified channel. This is exported to application as
1623 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
1625 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1627 * Fixed founder regaining problem with JOIN command on normal
1628 server. The notify for mode change must be sent always and
1629 not only if !cmd->pending. Affected file silcd/command.c.
1631 * Fixed the WHOWAS command's reply sending to support the
1632 lists correctly. Affected file silcd/command.c.
1634 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1636 * When sending JOIN command to router for processing the
1637 sender's old command identifier was not saved back to the
1638 sender's command context, fixed now. The affected file is
1641 * Create the key in JOIN command of the router did not return
1642 the channel key, added check for this. Affected file is
1645 * Fixed a channel ID update bug in JOIN command reply. Do
1646 not directly upgrade the ID but call the function
1647 silc_idlist_replace_channel_id if the ID was changed.
1648 Affected file silcd/command_reply.c.
1650 * Fixed memory leaks from command calling if it would fail.
1651 Affected file silcd/command.c.
1653 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1655 * Applied patches from cras:
1657 Memory leak fixes around libaries, irssi window resize fix,
1658 new silclist.h and silcdlist.h, all extern inline changed to
1661 * Removed dotconf from lib/dotconf, not needed anymore.
1663 * Removed TRQ from lib/trq, not needed anymore.
1665 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
1666 with server connections. Later this will be configurable
1667 in config file after new config file is done. Affected file
1670 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1672 * Fixed a crash in server related to channel announcements.
1673 Affected file silcd/server.c.
1675 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1677 * Fixed memory leaks in silc_server_create_new_channel*
1678 functions. Affected file silcd/server.c.
1680 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
1681 which ID was changed. This way the router will send the
1682 user list for the channel again, and server won't be in
1683 desync in some rare circumstances. Affected file is
1684 silcd/packet_receive.c.
1686 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1688 * Check for NULL socket pointer in the function
1689 silc_server_packet_send_to_channel_real. Affected file
1690 silcd/packet_send.c.
1692 * Fixed the BAN notify handling to correctly remove ban
1693 list. Affected file silcd/packet_receive.c.
1695 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1697 * Fixed some header addition to Toolkit distribution in
1698 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
1700 * Added lib/silcclient/client_ops_example.h as an template
1701 file for application programmers to quickly start using
1702 the SilcClientOperation functions in their application.
1703 Updated the lib/silcclient/README as well to tell about this
1704 nice file made available.
1706 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1708 * Call silc_server_remove_from_channels when removing client
1709 entry when NO_SUCH_CLIENT_ID was received. Affected file
1710 is silcd/command_reply.c.
1712 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1714 * Added server & router operator statistics updating. Affected
1715 file silcd/packet_receive.c and silcd/command.c.
1717 * Fixed the SERVER_SIGNOFF notify handling on normal server
1718 not to save the history information for clients. Same was
1719 fixed earlier in remove_clients_by_server function, but not
1720 here. Affected file silcd/packet_receive.c.
1722 * Raised the default connection-retry count from 4 to 7 in
1723 server. Affected file silcd/server.h.
1725 * Cancel any possible reconnect timeouts when we start the
1726 key exchange. Affected file silcd/server.c.
1728 * Do not reconnect on connection failure when SCONNECT was
1729 given. Affected files silcd/server.[ch].
1731 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1733 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
1735 * Fixed the NICK command to always give the unformatted
1736 nickname to the one giving the NICK command. If unformatted
1737 nickname is cached already it will be formatted and the
1738 local entry will always get the unformatted nickname.
1739 Affected file lib/silcclient/idlist.c.
1741 * Fixed some double frees from client library commands.
1742 Affected file is lib/silcclient/command.c.
1744 * Fixed CUMODE command in server to assure that no one can
1745 change founder's mode than the founder itself, there was a
1746 little bug. Affected file silcd/command.c.
1748 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1750 * Removed the SilcClientCommandDestructor from the client
1751 libary, it is not needed anymore. Affected files are
1752 lib/silcclient/silcapi.h, command[_reply].[ch],
1753 client_notify, idlist.c.
1755 * Fixed GETKEY command to first resolve client, and then
1756 resolve the server only if the client was not found, instead
1757 of resolving both at the same time. Affected file is
1758 lib/silcclient/command.c.
1760 * Added silc_client_start_key_exchange_cb and lookup the
1761 remote hostname and IP address before starting the key
1762 exchange with server. The affected file is
1763 lib/silcclient/client.c.
1765 * The server's public key is now saved using the IP address
1766 of the server and not the servername for the filename.
1767 The hostname public key filename is checked as an fall back
1768 method if the IP address based filename is not found.
1770 Fixed the GETKEY command to save the fetched server key
1771 in correct filename.
1773 Print the remote server's hostname now when new key is
1774 received during connection process. Affected file is
1775 irssi/src/silc/core/client_ops.c.
1777 * Return always our own public key to the client if it asks
1778 for it with GETKEY command. Affected file silcd/command.c.
1780 * Removed the use_auto_addr variable from default config
1781 file since it was in wrong section. Affected file is
1784 * Fixed TOPIC_CHANGE notification to not route it when it
1785 was sent using silc_server_send_notify_to_channel function.
1786 Affected file silcd/command.c.
1788 * Fixed silc_server_send_notify_kicked to send the kicker's
1789 Client ID also, it was missing. Affected files are
1790 silcd/command.c, silcd/packet_send.[ch].
1792 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1794 * Do not save client history information in SERVER_SIGNOFF.
1795 Fixes the bug in normal server that it does not detect
1796 the client becoming valid after the server becomes back
1797 online. Affected file silcd/server_util.c.
1799 * Added `sock_error' field into the SilcSocketConnection
1800 context. When error occurs during socket operation (read
1801 or write) the error is saved. Added also new function
1802 silc_socket_get_error to return human readable socket error
1803 message. Affected files are lib/silcutil/silcsockconn.[ch],
1804 lib/silcutil/unix/silcunixsockconn.c, and
1805 lib/silcutil/win32/silcwin32sockconn.c.
1807 * The server now prints the socket error message in the
1808 signoff for client. Affected file silcd/server.c.
1810 * Fixed the `created' channel information sending from router
1811 to server in JOIN command. Checks now whether the channel
1812 really was created or not and set it according that.
1814 Fixed the JOIN command to use the client entry's current
1815 ID during the joining procedure instead of the one it sent
1816 in the command (it is checked though), since it can change
1817 between the packet processing and command processing, and
1818 would just case unnecessary pain in the client end. Affected
1819 file silcd/command.c.
1821 * Fixed a channel key payload sending to use correct channel
1822 ID when the server was forced to change the channel's ID by
1823 router. Router sent the key payload with the old Channel ID.
1824 Affected file silcd/packet_receive.c.
1826 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1828 * Call silc_server_save_channel_key only if the key payload
1829 was provided in the JOIN command's command reply. Affected
1830 file silcd/command_reply.c.
1832 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1834 * Fixed silc_mp_sizeinbase to return the value correctly with
1835 MPI. Affected file lib/silcmath/mp_mpi.c.
1837 * Fixed the stop_server signal to correctly stop the scheduler
1838 and gracefully stop the server when SIGTERM or SIGINT signals
1839 are received. Affected file silcd/silcd.c.
1841 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1843 * Simple handling of TERM and HUP signals. Also added some log
1844 flushing call around. Affected file is
1847 * Fixed small bugs in silclog.c. Now buffering output will take
1848 effect after 10 seconds since startup: This will ensure that
1849 no important startup messages are lost. Also output redirection
1850 will preserve original format ([Date] [Type] message).
1851 Affected file is lib/silcutil/silclog.c.
1853 * Added two options to the config file, in the logging section:
1854 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1855 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1857 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1859 * Do not print the warning about log files not being initialized
1860 more than once to avoid excess logging. Affected file is
1861 lib/silcutil/silclog.c.
1863 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1864 the SIM copying in make install in Makefile.am.pre.
1866 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1868 * Rewritten silclog APIs. Globally interesting changes follows:
1869 silc_log_set_files() changed to silc_log_set_file().
1870 silc_log_set_callbacks() changed to silc_log_set_callback().
1871 ROBOdoc documented silclog header file.
1872 SilcLogCb now returns bool to wether inihibit the default
1873 handler or not (to keep the old behaviour return always TRUE).
1874 The new APIs should also fix the problem of the
1875 silcd_error.log file that was written in the current directory.
1878 Log files streams will remain opened after silc_log_set_file()
1879 call, means less CPU usage notably on high traffic servers.
1880 File streams are now full buffered, and flushed to the disk
1881 every 5 minutes, lesses HD activity and CPU usage.
1882 Messages can be redirected, allowing admins to configure
1883 one single logfile for all server messages.
1884 the silc_log_quick global variable to activate fast-logging.
1885 Affected files lib/silcutil/silclog.[ch]
1887 * Changed some code to conform new silclog APIs. Affected
1888 files are doc/example_silcd.conf.in, silcd/server.c
1889 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1892 * Fixed a memory leak that could occur in some situations.
1893 Affected file silcd/serverconfig.c.
1895 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1897 * Added the silc_client_del_client to remove the client from
1898 all channels as well. Affected file lib/silcclient/idlist.c.
1900 * Fixed the client library to correctly remove the client
1901 from all channels when the client entry is being destroyed.
1902 Affected file lib/silcclient/client_notify.c, command.c.
1904 * Added auto-nicking support to the client library. If the
1905 applicatio now sets client->nickname it will be sent to the
1906 server after connecting by the library. This way for example
1907 SILCNICK (or IRCNICK) environment variables will have effect
1908 and always change the nickname automatically to whatever
1909 it is wanted. Affected file lib/silcclient/client.[ch].
1911 * Renamed silc_server_command_bad_chars to the
1912 silc_server_name_bad_chars and moved it to the
1913 silcd/server_util.[ch]. Added also new function
1914 silc_server_name_modify_bad to return nickname that
1915 includes bad characters as new nickname without those
1916 bad characters. This check and modify is now used in
1917 silc_server_new_client when the username is initially set
1918 as nickname, so it must be checked to be valid nickname.
1919 Affected file silcd/packet_receive.c.
1921 * The nickname length is now taken from the packet for real
1922 and not trusted to strlen() since it clearly can return
1923 wrong length for nickname including bad characters. This
1924 also applies to channel names. Affected file silcd/command.c.
1926 * Removed the lib/silcsilm/modules directory. Modules are now
1927 compiled into the lib/silcsim. Fixed the copying of the
1928 modules to follow symbolic links in Makefile.am.pre.
1930 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1932 * Fixed silc_string_regexify list creation. Fixes bugs with
1933 BAN and INVITE commands in server. The affected file is
1934 lib/silcutil/unix/silcunixutil.c.
1936 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1938 * Removed the command destructor entirely from the server's
1939 command and command reply routines. It is not needed, and
1940 its usage was buggy and caused crashes. Affected files are
1941 silcd/command[_reply].[ch].
1943 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1945 * Cancel protocol and NULL sock->protocol if timeout
1946 occurred during protocol. Affected file silcd/server.c.
1948 * Cancel protocol timeouts always before calling the final
1949 callback, to assure that after final callback is called
1950 no other state will be called for the protocol anymore.
1951 Affected file silcd/protocol.c.
1953 * Print error log if incoming connection configuration could
1954 not be found. Affected file silcd/server.c.
1956 * Fixed JOIN command to correctly save the founder mode
1957 to the client on normal SILC server, when the channel
1958 was created by the router. Affected file silcd/command.c.
1960 * Fixed LIST command (hopefully) to send correct reply
1961 packets. Affected file silcd/command.c.
1963 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1965 * The silc_packet_receive_process now returns FALSE if the
1966 read data was invalid packet, and TRUE if it was ok.
1968 The server now checks that if unauthenticated connection
1969 sends data and its processing fails the server will close
1970 the connection since it could be a malicious flooder.
1972 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1974 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1976 * Make sure the warning about error opening a log file is
1977 printed only once and not everytime it fails (produces
1978 too much useless log). Affected file lib/silcutil/silclog.c.
1980 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1982 * Made the silc_server_daemonise() function more readable.
1983 Affected file silcd/server.c.
1985 * Pid file is now optional, the user may comment it out from
1986 the config file. Removed define SILC_SERVER_PID_FILE, we
1987 don't need a default any longer. Affected file
1988 configure.in.pre, lib/Makefile.am.pre.
1990 * Make some use of the pid file. The server now dies at startup
1991 if it detects a valid pid file on his path. The server would
1992 die anyway in this circumstance, because of the bind() failure.
1993 Affected file silcd/silcd.c.
1995 * No longer compiling lib/dotconf.
1997 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1999 * Fixed JOIN command parsing not to crash. Affected file
2000 lib/silcclient/command.c.
2002 * Fied the NICK_CHANGE notify to add the new client entry
2003 even it is resolved. This removes an <[unknown]> nick
2004 thingy bug in the client. Affected file is
2005 lib/silcclient/client_notify.c.
2007 * Do not try to allocate 0 bytes (efence does not like it)
2008 in lib/silccore/silccomand.c when encoding payload.
2010 * Do not take IRCNICK as nickname in Irssi SILC client since
2011 it is not possible to set nickname before hand connecting
2012 the server (TODO has an entry about adding auto-nicking
2015 * Changed the silc_server_command_pending to check whether
2016 there already exists an pending entry with the specified
2017 command, command identifier and pending callback. This is
2018 to fix IDENTIFY and WHOIS related crashes that may register
2019 multiple pending commands with same identifier. Affected
2020 file silcd/command.c.
2022 * Fixed the server to reconnect to the router even if it
2023 was already reconnecting and EOF was received. This to
2024 fix a possibility that the server wouldn't ever try to
2025 auto-reconnect to the router. Affected file silcd/server.c.
2027 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2029 * Fixed the server's password authentication to use the
2030 length of the locally saved password, and not the one
2031 sent in the packet. Affected file silcd/protocol.c.
2033 * Fixed same password authentication problem in the
2034 Authentication Payload handling routines in
2035 lib/silccore/silcauth.c.
2037 * Yet another password authentication problem fixed with
2038 channel password handling in silcd/command.c.
2040 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2042 * If first character of string in silc_parse_userfqdn is '@'
2043 then do not parse it. Affected file is
2044 lib/silcutil/silcutil.c.
2046 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2048 * Fixed minor bug in IDENTIFY command reply sending, which
2049 caused various weird problems during JOIN when it was
2050 resolving names for users. Affected file silcd/command.c.
2052 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2054 * Fixed the IDENTIFY command reply sending to chech better valid
2055 clients. It was possible to send incomplete list of replies.
2056 Affected file silcd/command.c.
2058 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2060 * Added silc_client_command[s]_[un]register functions now to
2061 dynamically register the commands in client library. Removed
2062 the static table of commands. This allows the client library
2063 to call commands without causing the application to know about
2064 what commands library has called.
2066 Removed the INFO command reply kludge to detect when the command
2067 was called by library. Now library use its own command reply
2068 function for INFO command.
2070 Added function silc_client_command_call to call a command.
2071 Application can use it to call command, not access the structure
2074 Now all commands that are sent by the client library (not
2075 explicitly sent by application) use own command reply functions.
2077 Affected files around lib/silcclient/ and in
2078 irssi/src/silc/core/.
2080 * Fixed the WHOIS command reply sending to chech better valid
2081 clients. It was possible to send incomplete list of replies.
2083 Fixed the WHOIS and IDENTIFY to send the request to router
2084 if normal server did not do it and did not find any results.
2086 Affected file silcd/command.c.
2088 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2090 * Moved the internal data from SilcClient context into its
2091 own file, not accesible to application. Affected files
2092 lib/silcclient/client.h and lib/silcclient/client_internal.h,
2093 and other files in client library.
2095 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2097 * Added doc/examples installation target in Makefile.am.pre.
2100 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2102 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
2103 commands the found client entry will be removed from the
2104 cache, after notifying application about the error. Affected
2105 file lib/silcclient/command_reply.c.
2107 * Changed the /MSG to check for exact nickname user gave, and
2108 not let `nick' match `nick@host' if it is only one found. Now,
2109 user must type the exact nickname (like nick@host2) even if
2110 there are no more than one same nicks found. This is to avoid
2111 a possibility of sending nickname to wrong nickname since
2112 `nick' could match `nick@host'. Affected file is
2113 irssi/src/core/silc-servers.c.
2115 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2117 * Do not print "you are now server operator" or similar when
2118 giving /away command. Affected files are
2119 irssi/src/silc/core/client_ops.c, silc-servers.h.
2121 * Made the silc_server_command_pending_error_check to send
2122 the same command reply payload it received back to the
2123 original sender of the command. This way all arguments
2124 that was received by the server will be received by the
2125 client too. Affected file silcd/command.c.
2127 * Added the silc_idcache_add to return the created cache entry
2128 to a pointer. Affected file lib/silccore/silcidcache.[ch].
2130 * Add global clients to expire if they are not on any channel.
2131 This is because normal server will never know if they signoff
2132 if they are not on any channel. The cache expiry will take
2133 case of these entries. This is done by normal servers only.
2134 The affected files are silcd/command_reply.c,
2135 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
2137 * If server receives invalid ID notification for WHOIS or
2138 IDENTIFY and the ID exists in the lists, it is removed.
2139 Affected file silcd/command_reply.c.
2141 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
2142 in client then client entry that it matches is searched and
2143 the nickname is printed on the screen for user. Affected
2144 file irssi/src/silc/core/client_ops.c.
2146 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2148 * Use cache entry expire time in the LIST command reply to
2149 purge old entries from the cache after the LIST command
2150 reply has been received. This way we don't have non-existent
2151 entries in the cache for too long. Affected file is
2152 silcd/command_reply.c.
2154 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2156 * If we are normal server, and we've not resolved client info
2157 in WHOIS or IDENTIFY from router, and it is global client,
2158 we'll check whether it is on some channel. If it is not
2159 then we cannot be sure about its validity and will resolve it
2160 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
2161 file silcd/command.c.
2163 * Search channel by name (if possible) rather than by ID
2164 in IDENTIFY command's command reply. Affected file is
2165 silcd/command_reply.c.
2167 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2169 * Distribute to the channel passphrase in CMODE_CHANGE notify.
2170 Updated specs and implemented it. Affected file silcd/command.c,
2171 silcd/packet_send.c and silcd/packet_receive.c.
2173 * Implemented the <founder auth> payload handling in the JOIN
2174 command. If provided all conditions for channel joining
2175 except requirement to provide correct passphrase can be
2176 overrided by the channel founder. Updated the protocol specs.
2177 Affected file silcd/command.c.
2179 Added support for founder auth in JOIN command in client
2180 library. Fixed the parsing of the JOIN command now to support
2181 all options as they should be. The affected file is
2182 lib/silcclient/command.c.
2184 * Optimized the WHOIS and IDENTIFY commands to send the request
2185 to router only if it includes nicknames or other names. If
2186 they include only IDs then check the local cache first before
2187 routing. Affected file is silcd/command.c.
2189 * Added channels topic announcements. Affected file is
2190 silcd/packet_receive.c and silcd/server.c.
2192 * Fixed the silc_server_send_notify_topic_set to really destine
2193 the packet to channel. Affected file silcd/packet_send.c.
2195 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
2196 library. Affected file lib/silcclient/client_notify.c.
2198 * Added UMODE announcements. Affected file silcd/server.c.
2200 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2202 * Memory leak fixes in:
2204 lib/silcutil/silcsockconn.c
2205 lib/silcske/silcske.c
2206 lib/silcske/groups.c
2208 lib/silccrypt/silcpkcs.c
2209 lib/silccore/silccommand.c
2210 lib/silccore/silcidcache.c
2215 * ROBOdoc documented the lib/silcske/groups.h file and a
2216 bit changed the interface for better.
2218 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2220 * Update the client entry context in the ID cache after
2221 nick change. Affected file lib/silcclient/command.c.
2222 Fixes the CUMODE command when regaining founder privileges,
2223 and a little WHOIS problem.
2225 * Fixed silc_net_gethostbyname to correctly call the
2226 inet_ntop. Affected file lib/silcutil/silcnet.c.
2228 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2230 * Added IPv6 support checking to the configure.in.pre, added
2231 also --enable-ipv6 option to override the check. Affected
2232 file configure.in.pre.
2234 * The silc_thread_create now calls the start function
2235 directly if threads support is not compiled in. Removes
2236 ugly #ifdef's from generic code. Affected files are
2237 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
2239 * Added silc_net_gethostby[name/addr]_async to asynchronously
2240 resolve. Affected files are lib/silcutil/silcnet.[ch].
2242 * Added support for rendering IPv6 based server, client and
2243 channel IDs. Affected file lib/silcutil/silcutil.c.
2245 * Added support for creating IPv6 based server IDs. Affected
2246 file is silcd/serverid.c.
2248 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2250 * Added silc_net_gethostby[addr/name] into the
2251 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
2252 routines. Added silc_net_is_ip[4/6]. Affected file is
2253 lib/silcutil/unix/silcunixnet.c. All routines that take
2254 address as argument now supports both IPv4 and IPv6 addresses.
2256 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2258 * Fixed LIST command reply sending in server. Affected file
2261 * Server now sends the kicker's client ID in the KICK notify
2262 to the kicked client. Affected file silcd/command.c.
2264 * The client library now parses the kickers client ID and
2265 UI displays it. Affected files lib/silcclient/client_notify.c
2266 and irssi/src/silc/core/silc-channels.c, module-formats.c.
2268 * Made all payload parsing function prototypes consistent.
2269 They all take now const unsigned char * and uint32 pair as
2270 the payload data instead of SilcBuffer. Changes all around
2271 the source tree. Other unsigned char* -> const unsigned char*
2272 changes around the tree as well.
2274 * Optimized SFTP client and server packet sending not to
2275 allocate new buffer for each packet but to recycle the
2276 first allocated buffer. Affected files are
2277 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
2279 * Optimized the SFTP client to use SilcList instead of
2280 SilcDList for requests, because it is faster. Affected file
2281 is lib/silcsftp/sftp_client.c.
2283 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
2284 into lib/silccore/silcid.[ch].
2286 Renamed silcpayload.[ch] into silcargument.[ch].
2288 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2290 * If client entry is deleted with active key agreement
2291 session, abort the session.
2293 The silc_client_abort_key_agreement now calls the completion
2294 callback with new SILC_KEY_AGREEMENT_ABORTED status.
2296 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
2299 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2301 * Don't use __restrict in older GCC's. Affected file is
2302 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
2304 * silc_net_localhost now attempts to reverse lookup the
2305 IP/hostname. Affected file lib/silcutil/silcnet.c.
2307 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
2308 command. It can be used to gain founder privileges at
2309 the same time when joining the channel.
2311 Defined that the SILC_NOTIFY_TYPE_KICKED send the
2312 kicker's client ID as well. Updated protocol specs.
2314 Defined that the server must send SILC_COMMAND_IDENTIFY
2315 command reply with error status to client who sent
2316 private message with invalid client ID.
2318 Updated the protocol specification.
2320 * Added silc_server_send_command_reply to send any
2321 command reply. Affected file silcd/packet_send.[ch].
2323 * Added silc_id_payload_encode_data to encode ID payload
2324 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
2326 * The server now send IDENTIFY command reply with error
2327 status if client ID in private message is invalid. Affected
2328 file silcd/packet_receive.c.
2330 * Save the server key file with server's IP address in
2331 the filename instead of hostname. The affected file is
2332 irssi/src/silc/core/client_ops.c.
2334 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2336 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
2339 * Added libtool support for compiling shared objects in
2340 lib/silcsim. Affected file configure.in.pre and
2341 lib/silcsim/Makefile.am. Original patch by cras.
2343 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2345 * Pid file configuration, and server's config file fixes
2346 patch by toma. Updated CREDITS file.
2348 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2350 * Fixed silc_client_channel_message to not try to decrypt
2351 the message twice if it resolved the destination client
2352 information. This could cause of dropping one channel
2353 message. Affected file lib/silcclient/client_channel.c.
2355 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2357 * Added silc_client_run_one into lib/silcclient/silcapi.h and
2358 lib/silcclient/client.c. This function is used when the SILC
2359 Client is run under some other scheduler, or event loop or
2360 main loop. On GUI applications, for example this may be
2361 desired to used to run the client under the GUI application's
2362 main loop. Typically the GUI application would register an
2363 idle task that calls this function multiple times in a second
2364 to quickly process the SILC specific data.
2366 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2368 * Fixed silc_server_drop() for dropping the supplementary
2369 groups as well, this could cause a security hole on some
2372 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2374 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
2377 * Write PID file after dropping privileges. Added -F option
2378 to run server on foreground. A patch by debolaz.
2379 Affected files silcd/server.c, silcd/silcd.c.
2381 * Fixed MOTD to return the MOTD file server name. Affected
2382 file silcd/command.c.
2384 * Added INFO command reply handling to the Irssi SILC Client.
2385 Affected file irssi/src/silc/core/client_ops.c.
2387 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2389 * Fixed the silc_idcache_list_* routines to really support
2390 the dynamic list. Fixes a crash. Affected file is
2391 lib/silccore/silcidcache.c.
2393 * Fixed the LIST command reply to really call LIST command's
2394 pending callbacks. Affected file silcd/command_reply.c.
2396 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2398 * Update conn->local_entry->nickname after giving NICK
2399 command. Affected file lib/silcclient/command.c.
2401 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
2403 * Added the [pid] option to the silcd configuration file
2405 Affected files: serverconfig.[ch] and silcd.c
2407 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2409 * Save fingerprint in WHOIS command reply in server.
2410 Affected file silcd/command_reply.c.
2412 * Fixed NICK commands pending callback registration.
2413 Affected file lib/silcclient/command.c.
2415 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2417 * Use ++server->cmd_ident when sending commands in server,
2418 instead of random number. Affected file silcd/command.c.
2420 * Fixed GETKEY command reply to call actually GETKEY pending
2421 command callbacks. Affected file silcd/command_reply.c.
2423 * A bit stricter check for nicknames. Check for same nickname
2424 in NICK command also. Affected file silcd/command.c.
2426 * Do not call INFO command everytime client ID changes, only
2427 during first connecting. Affected file lib/silcclient/client.c.
2429 * Set the new nickname only after successful command reply for
2430 NICK command is returned by server. Affected file
2431 lib/silcclient/command.c.
2433 * Remove nicknames from nicklist during server_signoff notify.
2434 Should fix /NAMES bit more. The affected file is
2435 irssi/src/silc/core/silc-channels.c.
2437 * Added `fingerprint' field to the SilcIDListData in the
2438 silcd/idlist.h to hold the fingerprint of the client's
2441 Send the fingerprint of the client's public key in WHOIS
2444 Affected files silcd/command.c, and silcd/idlist.[ch].
2446 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
2447 create fingerprint from given data.
2449 * Show the fingerprint of the client's public key in WHOIS.
2450 Affected files irssi/src/module-formats.[ch] and
2451 irssi/src/silc/core/client_ops.c.
2453 * Format the multiple same nicknames also during JOIN and
2454 NICK_CHANGE notifys. Affected file is
2455 lib/silcclient/client_notify.c.
2457 * Do not print error on screen for invalid private message
2458 payload since it can come if someone is sending private
2459 messages with wrong key. Affected file
2460 lib/silccore/silcprivate.c.
2462 * Fixed multiple concurrent /PING crash. Affected file
2463 lib/silcclient/command.c.
2465 * Changed the wrong ID encoding. All IP addresses must be
2466 in MSB first order in encoded format. They were encoded
2467 wrong and was in LSB format. Affected files are
2468 silcd/serverid.c, lib/silcutil/silcutil.c.
2470 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
2472 * Call the `connect' client operation through the scheduler
2473 in case of error. Affected file lib/silcclient/client.c.
2475 * Call the `failure' client operation even if the error
2476 occurred locally during a protocol. Affected file is
2477 lib/silcclient/protocol.c.
2479 * Added support of sending LIST command to router from normal
2480 server. This way normal server can get list of all channels
2481 in the network too. Fixed the channel list sending in the
2482 server too. Affected files are silcd/command.c, and
2483 silcd/command_reply.[ch].
2485 * Added silc_server_update_channels_by_server and
2486 silc_server_remove_channels_by_server. They are used during
2487 disconnection of primary router and in backup router protocol.
2488 Affected file silcd/server_util.[ch], silcd/server.c and
2489 silcd/server_backup.c.
2491 * Fixed channel adding to global list in IDENTIFY command
2492 reply in server. Affected file silcd/command_reply.c.
2494 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2496 * If the incoming packet type is REKEY or REKEY_DONE process
2497 that packet always synchronously. Fixes yet another MAC
2498 failed error on slow (dialup) connections. Affected file
2499 lib/silcclient/client.c and silcd/server.c.
2501 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2503 * Call check_version SKE callback for initiator too. Affected
2504 file lib/silcske/silcske.c.
2506 * Implemented fix for security hole found in the SKE that was
2507 fixed in the specification few days back; the initiator's
2508 public key is now added to the HASH value computation.
2509 Added backwards support for the old way of doing it too, for
2510 old clients and old servers. Affected file is
2511 lib/silcske/silcske.c.
2513 * Enabled mutual authentication by default in SKE. If initiator
2514 is not providing mutual authentication the responder will
2515 force it. This will provide the proof of posession of the
2516 private key for responder. The affected files are
2517 lib/silcclient/protocol.c and silcd/protocol.c.
2519 * Do not cache anymore the server's public key during SKE.
2520 We do mutual authentication so the proof of posession of
2521 private key is done, and if the server is authenticated in
2522 conn auth protocol with public key we must have the public
2523 key already. Affected file silcd/protocol.c.
2525 * Added new global debug variable: silc_debug_hexdump. If
2526 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
2527 file lib/silcutil/silclog.[ch].
2529 * Fixed compilation warning due to char * -> const char *.
2530 Affected files lib/silcutil/silcnet.h, and
2531 lib/silccore/silcauth.[ch].
2533 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2535 * Fixed CMODE command when new channel key was created. If
2536 the creation failed the old key was removed. Next time giving
2537 same command would crash the server since the old key was
2538 freed already. Affected file silcd/command.c.
2540 * Fixed the silc_server_announce_get_channels to not crash
2541 on reconnect. Affected file silcd/server.c.
2543 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2545 * Added silc_log_set_debug_string function to set a regex
2546 string to match for debug output. Only the function names,
2547 or filenames matching the given debug string is actually
2548 printed. This way it is possible to filter out those debug
2549 strings that user is not interested in.
2551 Fixed a bug in silc_string_regexify.
2553 Affected files lib/silcutil/silclog.[ch], and
2554 lib/silcutil/unix/silcunixutil.c.
2556 * Changed the -d options in both server and Irssi SILC client
2557 to take the debug string as argument. Affected files
2558 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
2560 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2562 * Added silc_hash_babbleprint to create a Bubble Babble
2563 Encoded fingerprint. The encoding is developed by Antti
2564 Huima (draft-huima-babble-01.txt), and it creates human
2565 readable strings out of binary data. Affected file
2566 lib/silccrypt/silchash.[ch].
2568 * Print the babble print now in addition of fingerprint as well
2569 in Irssi SILC client. Affected files are
2570 irssi/src/fe-common/silc/module-formats.[ch],
2571 irssi/src/fe-common/silc/core/client_ops.c.
2573 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2575 * Fixed a security problem found in SKE. The initiator's
2576 public key too is now added to the HASH hash value creation
2577 which is signed by the responder to create the SIGN value.
2578 This will prevent anyone in the middle to lie to the responder
2579 about the initiator's public key. If this is done now, the
2580 man in the middle will get caught. Updated the protocol
2583 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2585 * Better installation directory handling. Configure module
2586 paths and other paths automatically to example_silc* files
2587 in doc/. A patch by toma.
2589 * Fixed compiler warning from MPI library, and from SILC RNG.
2592 * Added SILC_SERVER_PID_FILE to define the pid file for server.
2593 It can be configured with ./configure. A patch by toma.
2595 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2597 * Find correct make to use in prepare-clean. A patch by
2598 toma. Affected file prepare-clean.
2600 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
2602 * Added irssi variables use_auto_addr, auto_bind_ip,
2603 auto_bind_port and auto_public_ip.
2605 * Changed the interface for silc_client_send_key_agreement
2606 in lib/silcclient/silcapi.h
2610 irssi/src/silc/core/silc-core.c
2612 lib/silcclient/silcapi.h
2613 irssi/src/silc/core/silc-channels.c

2619 * Added silc_pkcs_public_key_compare to compare two
2620 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
2622 * Check that the client who set the founder mode on the
2623 channel is the same client that is giving the founder
2624 mode to itself. It is done by comparing the saved public
2625 key (it is saved even in the authentication is passphrase).

2633 * Process the DISCONNECT packet through scheduler in the
2634 client library. Affected file lib/silcclient/client.c.
2636 * Fixed the silc_client_packet_parse to not to increase
2637 the packet sequence number if the conn->sock and the
2638 current socket connection is not same. This can happen
2639 for example during key agreement when the conn includes
2640 multiple socket connections (listeners). Affected file
2641 lib/silcclient/client.c.
2643 * The sender of the file transfer request now provides also
2644 the pointer (listener) for the key exchange protocol. If
2645 the listener cannot be created then it sends empty key
2646 agreement and lets the receiver provide the listener.
2648 Added `local_ip' and `local_port' arguments to the
2649 silc_client_file_send. If they are provided they are used,
2650 if not then it will attempt to find local IP address, if
2651 not found or bind fails then the remote client will provide
2654 Affected files are lib/silcclient/client_ftp.c and
2655 lib/silcclient/silcapi.h.
2657 * Extended the FILE SEND command to support defining the
2658 local IP and port for key exchange listener. They are

2663 * Defined to WHOIS command reply the sending of fingerprint
2664 of the client's public key (if the proof of posession of the
2665 corresponding private key is verified by the server).
2666 Updated to the protocol specification.
2668 * Added support of receiving the client's public key's
2669 fingerprint in command reply in client library. Affected
2670 file is lib/silcclient/command_reply.c, and
2671 lib/silcclient/idlist.[ch].

2730 preserve the WHOWAS info for the client. Affected file
2731 silcd/server_util.c.
2733 * Fixed SERVER_SIGNOFF notify handling in the server. The
2734 server is now able to process incoming SERVER_SIGNOFF notify
2735 for a server that it doesn't even know about. It will remove
2736 the clients provided in the notify. Affected file
2737 silcd/packet_receive.c.
2739 * Check for partial packet in data queue after every packet that
2740 was found from the queue. Return and wait for more data if
2741 there is partial data in queue. Affected file is

2759 irssi/src/fe-common/silc/module-formats.[ch].
2761 * Wrote a help file for FILE command.
2763 * Added silc_rng_global_get_byte_fast to get not-so-secure
2764 random data as fast as possible. Random data is read from
2765 /dev/urandom if available and from the SILC RNG if not
2766 available. It is used in padding generation. Affected file
2767 lib/silccrypt/silcrng.[ch].
2769 * All packets in client library are now processed synchronously.
2770 Optimized packet processing a lot. Affected file
2771 lib/silcclient/client.c.

2782 * Assure that silc_client_notify_by_server_resolve does not
2783 resolve the client information multiple times. If it cannot
2784 be found by the first it cannot be found at all. Affected
2785 file lib/silcclient/client_notify.c.
2787 * Fixed WHOWAS command reply calling. Affected file
2788 lib/silcclient/command_reply.c.
2790 * Removed all references to silc_idlist_get_client from the
2791 Irssi SILC client since that call is internal call used by
2792 the library. The Irssi SILC client will use now client
2793 retrieval functions found in silcapi.h.
2795 * Fixed a bug in resolving nickname info before sending
2796 private message. It used freed memory. Affected file
2797 irssi/src/silc/core/silc-servers.c.

2819 Affected file lib/silcutil/silcnet.[ch].
2821 * If key exchange or rekey protocol is active for a connection
2822 parse all packets syncronously since there might be packets
2823 in packet queue that we are not able to process without first
2824 processing packets before them. Affected file silcd/server,
2825 lib/silcclient/client.c.
2827 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2828 whether library should continue processing the packet.
2829 Affected file lib/silccore/silcpacket.h.

2902 * Call the silc_server_udpate_servers_by_server in the
2903 primary router that comes back online in the backup resuming
2904 protocol. Otherwise it routes packets wrong. Affected file
2905 silcd/server_util.[ch], silcd/server_backup.c.
2907 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2909 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2910 lib/silcutil/silcbuffmt.[ch].

2913 length. Affected file lib/silccore/silcpacket.[ch].
2915 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2916 length for maximum padding up to 128 bytes). Affected
2917 file lib/silccore/silcpacket.h.
2919 * Removed all backwards support for old 0.5.x MAC thingies.
2920 The SILC packet header change makes it impossible to be
2921 backwards compatible.
2923 * Send the ENDING packet with timeout in the backup resuming
2924 protocol. This is to assure that all routers has connected
2925 to the primary router. Affected file silcd/server_backup.c.
2927 * Changed the RNG to take the first IV from random data. It
2928 used to take it from zero actually. Changed the RNG also
2929 to use /dev/urandom during session. /dev/random is used
2930 in initialization. Affected file lib/silccrypt/silcrng.[ch].

2935 (the packet length) encrypted. Affected files aroung the
2936 code tree, lib/silccore/silcpacket.[ch]. Removed the
2937 SilcPacketCheckDecrypt callback. It is not needed anymore
2938 since the silc_packet_receive_process will determine now
2939 whether the packet is normal or special.

2952 * Allow backup router to announce servers. All servers
2953 announced by backup router are added to the global list
2954 automatically. Update hte server's socket to our primary
2955 router also when backup router announces a server.
2956 Affected file silcd/packet_receive.c.
2958 * Do not update the client->router in the function
2959 silc_server_udpate_clients_by_server if the client is on
2960 global list. We might fail to find any specific server
2961 for locally connected clients and local cell clients. They
2962 should still use the `from' and not `to' as client->router.
2963 This fixes backup router resuming protocol. Affected file
2964 silcd/server_util.c.
2966 * Decrease channel statistics count only if the channel
2967 deletion worked. Affected files are silcd/server.c and
2968 silcd/server_util.c.

2988 to the router it came from. Affected file is
2989 silcd/packet_send.c. Fixed memory leak too.
2991 * Announce informations for incoming router connection, but
2992 only after checking if it is replaced by backup router.
2993 Affected file silcd/packet_receive.c.
2995 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

2998 router environment. Affected file silcd/server_backup.c.
3000 * Route packet only to one router in the function
3001 silc_server_packet_send_to_channel. Affected file is
3002 silcd/packet_send.c.
3004 * Fixed silc_server_send_notify_dest to set the broadcast
3005 flag. Fixed the silc_server_send_notify_topic to actually
3006 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
3007 Affected file silcd/packet_send.c.
3009 * Changed the SFTP Filesystem interface. Changed the
3010 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
3011 the filesystem operation function. The SilcSFTPFilesystem
3012 is now a context that is allocated by all filesystem allocation
3013 functions and it already includes the operations structure
3014 and filesystem specific context. It is given as argument
3015 now to the silc_sftp_server_start. This made the interface
3016 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
3017 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
3019 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3021 * Changed the backup router adding and getting interfaces
3022 in the server. The router that will be replaced by the
3023 specified backup router is now sent as argument. Affected

3084 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
3085 in the server to indicate disabled entry. All data read
3086 from the connection will be ignored and no data is sent
3087 for entry that is disabled. Affected files are
3088 silcd/idlist.h, silcd/server.c.

3136 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3138 * Defined the file transfer to the SILC Protocol. Added
3139 new packet type SILC_PACKET_FTP and defined File Transfer
3140 Payload. The mandatory file transfer protocol is SFTP
3141 (SSH File Transfer Protocol). Affected file in addition
3142 of the internet draft is lib/silccore/silcpacket.h.
3144 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
3145 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
3146 is used as part of backup router protocol when the primary
3147 router of the cell is back online and wishes to resume
3148 the position as primary router.
3150 * Redefined the MAC generation keys in the protocol. The
3151 same key is not used anymore in both direction. Both
3152 direction will now use different keys for sending and
3153 receiving. This fixes a potential security flaw. This
3154 change causes incompatibilities in the protocol.
3156 * Redefined also the MAC computation from the packet.
3157 An packet sequence number is now added to the MAC
3158 computation. This prevents possible replay attacks against
3159 the protocol. This change too causes incompatibilities
3162 Added `sequence' field to the SilcPacketContext to hold
3163 the current sequence number for the packet.
3165 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3167 * Added `created' field to the SilcIDListData in the file
3168 silcd/idlist.h to indicate the time when the entry was
3171 * Added `created' field to the SilcChannelEntry too. Affected
3172 file silcd/idlist.h.
3174 * Added `creation_time' aguments to all the announcement functions
3175 in the server. If it is provided then only the entries that
3176 was created after the provided time frame are actually
3177 announced. Affected file silcd/server.[ch].
3179 * The protocol says that the Channel ID's IP address must be
3180 based on the router's IP address. Added check for this in
3181 the silc_server_new_channel when processing incoming New Channel
3182 Payload. Affected file silcd/packet_receive.c.
3184 * Print out the correct version with --version in SILC client.
3185 Affected file irssi/src/silc/core/silc-core.c.
3187 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3189 * Fixed WHOWAS command to check for completnes of the client
3190 entry always, not just when the command is coming from client.
3191 Affected file silcd/command.c.
3193 * Added new function silc_server_packet_queue_purge to purge the
3194 outgoing data queue to the network. After the function returns
3195 it is guaranteed that the outgoing packet queue is empty.
3196 Affected file silcd/packet_send.[ch].
3198 * Purge the outgoing packet queue in the rekey protocol's final
3199 callback to assure that all rekey packets go to the network
3200 before quitting the protocol. Affected file silcd/server.c.
3202 * Added silc_client_packet_queue_parse as similar function as
3203 in server to the client library. The affected file is
3204 lib/silcclient/client.c.
3206 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3208 * Splitted silcd/server.c and created silcd/server_util.[ch]
3209 for utility functions.
3211 * Added new socket flag SILC_SF_DISABLED to indicate that the
3212 connection is open but nothing can be sent to or received from
3213 the connection. Affected file lib/silcutil/silsockconn.[ch].
3214 The checking for disabled socket is checked in the low level
3215 silc_socket_write and silc_socket_read functions.
3217 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3219 * Allow only nicknames and channel names that fits into the
3220 7-bit unsigned char ASCII set. Affected file silcd/command.c.
3222 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3224 * When processing JOIN command reply in server check that if
3225 the channel exists in our global list we'll move it the local
3226 list. Affected file silcd/command_reply.c.
3228 * Fixed the check whether client is joined on the channel already
3229 in JOIN command. Affected file lib/silcclient/command.c.
3231 * Fixed the JOIN command reply to check whether the channel
3232 already exists. Affected file lib/silcclient/command_reply.c.
3234 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3236 * Added silc_ske_status_string to map the SKE error numbers
3237 to readable strings. The affected files are
3238 lib/silcske/silcske[_status].[ch].
3240 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3242 * Do not show the private channels on the WHOIS channel list
3243 as it is not allowed by the protocol. The affected file is
3246 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3248 * Assure that the packet length digged from the actual packet
3249 is something sensible in the silc_packet_decrypt_rest_special
3250 in lib/silccrypt/silcpacket.c.
3252 * Free and NULL the allocated pointer in silc_hmac_alloc if
3253 the HMAC allocation fails. The affected file is
3254 lib/silccrypt/silchmac.c.
3256 * Print the selected security properties to the log files in
3257 the server. Affected file silcd/protocol.c.
3259 * Add SKE's reference counter even if calling the completion
3260 callback manually. Otherwise it goes negative, although it
3261 does not cause any problems. The affected file is
3262 lib/silcske/silcske.c.
3264 * Remove the client entry with short timeout after giving the
3265 KILL command. Affected file lib/silcclient/command.c.
3267 * Fixed to send error reply in WHOIS and IDENTIFY commands in
3268 case all found clients are already disconnected (WHOWAS would
3269 found them) in the server. Affected file silcd/command.c.
3271 * Update the last_receive (time of last data received) to be
3272 updated only when received private or channel message so that
3273 the idle time showed in WHOIS makes more sense.
3275 * Added boolean field `valid' in to the SilcClientEntry in the
3276 client library to indicate whether the entry is valid or not.
3277 This fixes the nickname change bug on channel when changing
3278 the nickname to be same than the old (like nick to Nick) the
3279 nickname formatter doesn't set the new nick anymore to Nick@host.
3280 Affected file lib/silcclient/idlist.[ch].
3282 * Now actually fixed the nickname changing on disconnection.
3283 Added new function silc_change_nick to the Irssi SILC Client.
3284 Affected file irssi/src/silc/core/client_ops.c,
3285 irssi/src/silc/core/silc-nicklist.[ch].
3287 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3289 * Check that the public key exists in the GETKEY command before
3290 trying to encode it. Affected file silcd/command.c.
3292 * Print some notifications on received public keys with GETKEY
3293 command in the Irssi SILC Client. Affected files are
3294 irssi/src/fe-common/silc/module-formats.[ch],
3295 irssi/src/silc/core/client_ops.c.
3297 * Use IDENTIFY command to resolve the server information in the
3298 GETKEY command instead of INFO command. Affected file
3299 lib/silcclient/command.c.
3301 * All command reply functions in the client library now calls
3302 the pending command reply callbacks even if an error has
3303 occurred. The server has done this a long time and now it was
3304 time to move the client library to this as well. Now all
3305 errors can be delivered back to the pending command reply
3306 callbacks if necessary. Affected files are
3307 lib/silcclient/command[_reply].[ch].
3309 * Change the nickname on disconnection back to the username
3310 because in reconnect the server will enforce it to it anyway.
3311 Affected file irssi/src/silc/core/silc-servers.c.
3313 * Fixed a config file parsing bug in the Irssi SILC client.
3314 Affected file irssi/src/silc/core/clientconfig.c.
3316 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3318 * When printing the channel mode on JOIN, verify that the
3319 channel key and channel's HMAC are valid. Affected file
3320 irssi/src/silc/core/client_ops.c.
3322 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3324 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
3325 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
3326 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
3328 * Removed channel key rekey task deleting from the function
3329 silc_server_save_channel_key. Affected file silcd/server.c.
3330 Added explicit timeout task context instead that is used to
3331 delete the task if we are registering a new task before the
3332 new task has elapsed.
3334 * When channel key rekey occurs the client library now saves
3335 the old channel key for a short period of time (10 seconds) and
3336 is able to use it in case some is still sending channel
3337 messages encrypted with the old key after the rekey. Affected
3338 file lib/silcclient/[idlist.h|client_channel.c].
3340 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3342 * Added check to the silc_server_new_id_real to not accept
3343 new ID if it is the sender's own ID. Affected file is
3344 silcd/packet_receive.c.
3346 * Assure that we do not announce ourself or the one we've
3347 sending our announcements when we're router and are announcing
3348 servers to our primary router. Affected file silcd/server.c.
3350 * Fixed silc_server_command_identify_check_client to assemble
3351 correct WHOIS packet. It send corrupted WHOIS packet and
3352 caused problem with router to router connections. Affected
3353 file silcd/command.c.
3355 Fixed also silc_server_command_whois_check the same way
3356 as for the IDENTIFY command.
3358 * Added new SilcIDListStatus to the server in the SilcIDListData
3359 structure. The status now includes the current status of
3360 the entry (like registered, resolved etc.). Affected file
3361 silcd/idlist.[ch]. Defined a bunch of different status types
3362 as well. This replaced the old boolean registered field as well.
3364 Added resolve_cmd_ident field to the SilcClientEntry structure
3365 too so that if the entry is for example being resolved so
3366 another command may attach to the same pending command reply
3367 without requiring to resolve the same entry again. This concept
3368 should optimize the WHOIS and the IDENTIFY resolving under
3369 heavy load by taking away unnecessary resolving for entries
3370 that are being resolved already.
3372 Added support for adding multiple pending commands for one
3373 command idenfier. Affected file silcd/command[_reply].[ch].
3375 * Fixed WHOIS and IDENTIFY save to remove the cache entry
3376 before deleting the data. Otherwise the hash table will have
3377 freed data in comparison functions. Affected file is
3378 silcd/command_reply.c.
3380 * Fixed silc_idlist_replace_client_id to add the new entry to
3381 the cache with NULL nickname. Otherwise there will be invalid
3382 memory as the nickname after the nickname is freed. Affected
3383 file silcd/packet_receive.c.
3385 * Fixed the silc_idlist_get_clients_by_hash. The entries was
3386 saved into wrong slots because the previous number of entries
3387 was not taken into account. Affected file silcd/idlist.c.
3388 Fixed same thing in silc_idlist_get_clients_by_nickname too.
3390 * If we are router and we receive JOIN notify to a channel that
3391 does not have any users then notified client is marked as the
3392 channel founder, as it is it. The affected file is
3393 silcd/packet_receive.c
3395 * Added to the extended hash table API's table_del_*ext functions
3396 the destructor as argument too, so that the caller can decide
3397 which destructor to use or whether to use destructor at all.
3398 Affected file lib/silcutil/silchashtable.[ch].
3400 * Fixed ID Cache purging. It actually deleted the entries from
3401 the hash table after the data was freed. The hash table ended
3402 up comparing freed memory. The affected file is
3403 lib/silccore/silcidcache.c.
3405 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3407 * Fixed Irssi SILC client's KILL command's HELP syntax.
3409 * The USERS command now resolves the detailed user information
3410 if the userinfo field is missing. Affected file is
3411 lib/silcclient/command_reply.c.
3413 * Do not print error in silc_file_read if the read file does
3414 not exist. Just silently return NULL. Affected file is
3415 lib/silcutil/silcutil.c.
3417 * Fixed the silc_log_output to not wine about NULL filename
3418 and to not create some bogus " " filename. Affected file is
3419 lib/silcutil/silclog.c.
3421 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3423 * Fixed various printing bugs on the user interface in the
3424 Irssi SILC Client. Minor changes that were forgotten from
3427 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3429 * Fixed the configure.in.pre and the compilation and distribution
3430 environment to support the new autoconf 2.52. That version is
3431 now required to compile the CVS trunk.
3433 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3435 * Renamed function silc_parse_nickname to silc_parse_userfqdn
3436 to generally parse user@fqdn format strings. Affected file
3437 lib/silcutil/silcutil.c.
3439 * Added nickname_format and nickname_force_format fields to the
3440 SilcClientParams structure. The first one defines the format
3441 for the nicknames that the library will enforce if the receives
3442 multiple same nicknames. The second one is boolean value and
3443 can be used to force the library to always enforce the format
3444 to the nicknames regardles whether there are multiple nicknames
3445 or not. This configurable formatting was employed to flexibly
3446 support accessing multiple nicknames from the user interface.
3447 The userinterface can now set the nicknames to what ever format
3448 they prefer. Affected file lib/silcclient/silcapi.h.
3450 Added function silc_client_nickname_format to the file
3451 lib/silcclient/idlist.c. It performs the nickname formatting.
3453 Added new field `hostname´ to the SilcClientEntry context.
3454 It holds the hostname of the client. Affected file is
3455 lib/silcclient/idlist.h.
3457 * Irssi SILC Client sets the nicknames in nick@hostn format.
3458 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
3459 irssi/src/silc/core/silc-core.c.
3461 The WHOIS printing now also shows both the real nickname and
3462 the formatted nickname so that user knows how to access the
3463 user if there are multiple same nicknames cached. Affected
3464 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
3465 printing formatting too to take the hostname now as a separate
3466 argument. The Affected file is
3467 irssi/src/fe-common/silc/modules-formats.[ch].
3469 * Changed the silc_client_get_clients_local to accept the formatted
3470 nickname as argument. It accepts the real nickname too but the
3471 formatted nickname can be used to find the true entry from
3472 multiple entries. Affected file lib/silcclient/silcapi.h and
3473 lib/silcclient/idlist.c.
3475 * Added nickname_format_parse field to the SilcClientParams.
3476 It is a callback function provided by the application to parse
3477 the nickname out of the formatted nickname string. The library
3478 calls it to get the nickname from the formatted string. Since
3479 the application generally knows better the format of the nickname
3480 string it parses it instead of the library, even though library
3481 encodes the formatted string. If the callback function is not
3482 provided then the library will use the string as is. The
3483 affected file is lib/silcclient/silcapi.h.
3485 * All the nickname strings passed to the client library in
3486 commands are now expected to be formatted nickname strings.
3487 If the command does not support the formatted nickname string
3488 it will assume that the sent string is the actual nickname.
3489 Affected file lib/silcclient/command.c.
3491 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3493 * Added public key authentication support to OPER and SILCOPER
3494 commands in the client library. Affected file is
3495 lib/silcclient/command.c.
3497 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3499 * Changed the get_auth_methdod client operation to be asynchronous.
3500 It can be async if the application resolves the authentication
3501 method from the server during the negotiation. Added new
3502 SilcGetAuthMeth completion callback that the application will
3503 call after resolving the authentication method.
3505 Added function silc_client_request_authentication_method that
3506 the application can use to resolve the authentication method
3507 from the server. Added also SilcConnectionAuthRequest callback
3508 that the library will call after the server has replied. The
3509 application can call this function if it does not know the
3510 current authentication method.
3512 Affected files are lib/silcclient/client.c and
3513 lib/silcclient/silcapi.h.
3515 * The Irssi SILC client now automatically resolves the authentication
3516 method incase any configuration information is not present (and
3517 currently there never is). The affected file is
3518 irssi/src/silc/core/client_ops.c.
3520 * Fixed public key authentication from the client library.
3521 Affected file lib/silcclient/protocol.c. Changed also the
3522 protocol specification about the public key authentication in
3523 the connection authentication protocol. The actual data to be
3524 signed is now computed with a hash function before signing.
3526 * Fixed the public key authentication from the server as well.
3527 Affected file silcd/protocol.c.
3529 * Removed the mlock()'s from the memory allocation routines.
3530 Affected file lib/silcutil/silcmemory.c. The ./configure does
3531 not check anymore for the mlock(). Affected file is
3534 * Fixed USERS command in server to allow the execution of the
3535 command for private and secret channels if the client sending
3536 the command is on the channel. Affected file silcd/command.c.
3538 * Fixed silc_client_get_clients_local to return the clients
3539 count correctly. It could return wrong value. Affected file
3540 lib/silcclient/idlist.c.
3542 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3544 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
3545 types. The assembler optimizations seemed not to like 64-bit
3546 data types. The assmebler optimizations thus are now enabled
3547 also for BSD systems as opposed to only enable them for Linux.
3549 * Do not check for threads at all on BSD systems. Affected
3550 file configure.in.pre.
3552 * Removed -n and -h options from the Irssi SILC Client since
3553 they are not used in silc.
3555 * Fixed the prime generation to assure that the first digit
3556 of the generated random number is not zero since our conversion
3557 routines does not like number strings that starts with zero
3558 digit. If zero digit is seen the random number is regenerated.
3559 This caused some corrupted RSA keys when the zero first digit
3560 was met. Affected file lib/silcmath/silcprimegen.c.
3562 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3564 * Fixed WIN32 configuration in the ./configure script.
3565 Fixed to include xti.h on environments that has it.
3566 Patches by Carsten Ilchmann and andrew.
3568 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3570 * Changed the silc_id_create_client_id to be collision
3571 resistant. It is now assured that there cannot be created
3572 two same client ID's. I suspect that some weird bugs in
3573 the server were actually caused by duplicate Client IDs.
3574 Affected file silcd/serverid.[ch]. A router receiving
3575 new ID now also assures and informs the sending server
3576 if the ID caused collision.
3578 * Changed the silc_id_create_channel_id to also assure that
3579 there are no collisions.
3581 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3583 * Statement about ignoring the Mutual Authentication flag when
3584 performing rekey with PFS was a bit misleading. It is ignored
3585 if it was set in the initial negotiation, it cannot be even
3586 set in the rekey. Fixed in the ke-auth draft. Started the
3587 new versions of the protocol drafts in the doc/.
3589 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3591 * Fixed a bug in silc_client_command_identify_save when saving
3592 new channel information. The channel name was no duplicated
3593 and caused crash on exit. Affected file is
3594 lib/silcclient/command_reply.c.
3596 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3598 * Fixed the getkey command handling in the server. Send just
3599 empty OK reply to the sender if the key could not be fetched
3600 (but everything else was ok, like the key just was not available).
3601 Changed the public key parameter to optional in the protocol
3602 specs so that empty OK reply can be sent. Affected file
3605 Added a message to Irssi SILC client to tell to user if the
3606 server did not return a public key.
3608 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3610 * Fixed a channel key regeneration bug. It registered new
3611 timeout tasks exponentially until all system resources were
3612 used. Affected file silcd/server.c.
3614 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3616 * Added the SILC Document generator to the scripts/silcdoc.
3617 It can be used to generate the Toolkit Reference Manual out
3618 of the source tree. Internally it will also use the RoboDoc
3619 generator now imported in util/robodoc.
3621 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3623 * Added couple of return's in rekey protocol if error orccurred
3624 during the protocol. The execution must be terminated.
3625 Affected file silcd/protocol.c. Also, terminate the protocol
3626 always with timeout.
3628 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3630 * The client's Client ID was created initally from the wrong
3631 nickname (it could have been in format nick@host) in the
3632 silc_server_new_client. Affected file silcd/packet_receive.c
3634 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3636 * Added some SILC_LOG_ERROR's to various error conditions
3637 if client could not be added to ID cache. Affected files
3638 silcd/packet_receive.c and silcd/server.c.
3640 * When client's sock->user_data is freed, NULL also the
3641 client->router and client->connection pointers. Added check
3642 for these pointers being NULL to various places around the
3643 code. Affected file silcd/server.c.
3645 * Added client->data.registered == TRUE checks to various
3646 places around the code to assure that unregistered client's
3647 are not handled when it is not allowed. Affected file
3650 * Added `bool registered' fields to all
3651 silc_idlist_[server|client]_get_* routines to indicate whether
3652 the fetched client needs to be registered or not. Affected
3653 file silcd/idlist.[ch].
3655 * Add your own entry as registered to the ID cache in the
3656 server. Affected file server.c.
3658 * Fixed a bug in silc_server_new_server. The SilcServer was
3659 set as the new server's context instead of SilcServerEntry.
3660 This naturally caused some weird bugs.
3662 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3664 * Do not delete the channel rekey task when adding it
3665 for in silc_server_create_channel_key.
3667 * Changed the silc_server_create_channel_key to return
3668 TRUE or FALSE to indicate the success of the channel key
3671 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3673 * Fixed MSVC++ project files and added missing files to

3679 does not have it defined. Affected files are
3680 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3682 * Fixed buffer overflow from Irssi SILC Client. Affected
3683 file irssi/src/fe-common/core/themes.c.
3685 * Fixed double free in client library in the file
3686 lib/silcclient/client.c when disconnecting from server.
3688 * Applied double free patch from cras to Irssi SILC client.
3689 Affected files irssi/src/core/[modules/expandos].c
3691 * Fixed the disconnection handling to Irssi SILC Client.
3692 The application must call silc_client_close_connection
3693 in ops->connect client operation in case of failure of
3694 the connection. Affected file is
3695 irssi/src/silc/core/client_ops.c.
3697 * Do not set sock->protocol to NULL in the function
3698 silc_client_close_connection after executing the protocol's
3699 final callback since the sock might not be valid anymore.
3700 Affected file lib/silcclient/client.c.
3702 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3704 * Do not enable SILC_THREADS if the linking with libpthread
3705 did not happen. Affected file configure.in.pre.
3707 * Added notion to protocol specification that server must
3708 verify the sent authentication payload with CMODE when
3709 setting the channel founder key. Implemented it to the
3710 server. Affected file silcd/command.c.
3712 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3714 * Added _EXTRA_DIST SILC distribution variable to the
3715 distributions file. It is used to conditionally add extra
3716 files or directories to the specific distribution. Affected
3717 files ./prepare, Makefile.am.pre and distributions.
3719 Removed the `_' from the start of the distribution names.
3722 * Added README.WIN32 for instructions to compile the Toolkit
3725 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3727 * Fixed a double free in disconnection in the server. Affected
3728 file is silcd/server.c.
3730 * Fixed the lib/silcske/groups.c to work now also with GMP
3731 MP library. The string conversion did not work when using
3732 specific base and the base is indicated in the string as well.
3734 * Created win32/ directory which now includes MSVC++ specific
3735 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3736 It will appear only in the toolkit distribution
3738 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3740 * Changed the key material distribution function in case when
3741 the hash output is too short. The data is now concatenated
3742 a bit differently than it used to. Made the change to the
3743 SKE protocol specification.
3745 * Added better GMP detection to configure.in.pre. A patch
3748 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3750 * Fixed a minor bug in SKE that might cause some problem on
3751 some platforms. Affected file lib/silcske/silcske.c.
3753 * Added the cookie checking for initiator in the SKE. It checks
3754 that the responder returns the sent cookie unmodified. The
3755 affected file is lib/silcske/silcske.c. Added new SKE
3756 error type INVALID_COOKIE that can be sent during the
3757 negotiation. Fixed some memory leaks as well.
3759 * Added the "invalid cookie" error message to Irssi SILC client's
3762 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3764 * Added `task_max' field to the SilcClientParams to indicate
3765 the maximum tasks the scheduler can handle. If set to zero,
3766 default values are used. Affected file lib/silcclient/silcapi.h.
3768 * Fixed memory leaks in silc_client_close_connection. Affected
3769 file lib/silcclient/client.c.
3771 * Added silc_client_del_client_entry to client library to free
3772 all memory of given client entry. Affected file is
3773 lib/silcclient/idlist.[ch].
3775 * Added new functions silc_client_del_channel and
3776 silc_client_del_server to delete channel and server entries.
3777 Affected file lib/silcclient/[silcapi.h/idlist.c].
3779 * Removed silc_client_del_client_by_id from silcapi.h.
3781 * Fixed the INFO command to return the server's own info
3782 correctly when querying by Server ID. Affected file is
3785 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3787 * Removed the non-blocking settings in WIN32 code in the
3788 silc_sock_[read/write] and added SleepEx instead. Affected
3789 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3790 of input data is now checked with FIONREAD and ioctlsocket.
3792 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3794 * Call silc_schedule_task_del_by_context in the
3795 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3796 Affected file lib/silccore/silcprotocol.c.
3798 * Call silc_protocol_cancel for active protocols in the
3799 silc_server_close_connection if the funtion
3800 silc_server_free_sock_user_data has not been called.
3801 Affected file silcd/server.c.
3803 * Generic tasks cannot be deleted using the del_by_fd
3804 task deleting function since generic tasks does not match
3805 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3807 * Added a notion to SILCOPER help file that the SILCOPER works
3808 only on router server, not on normal server.
3810 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3812 * Added for WIN32 support for the new scheduler as well.
3813 Affected file lib/silcutil/win32/silcwin32schedule.c.
3815 * Fixed the SHA1 implementation to work on various platforms.
3817 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3819 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3820 API. It is part of the scheduler now. Everything else is
3821 as previously but some functions has changed their names.
3822 Checkout the lib/silcutil/silcschedule.h for the interface.
3823 Updated all applications to use the new interface. Affected
3824 files are lib/silcutil/silcschedule.[ch].
3826 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3828 * Found a bug in the SKE implementation. The HASH value,
3829 specified by the protocol, was not computed correctly. The
3830 public key of the responder was not added to the computation
3831 even though it is mandatory. Affected file lib/silcske/silcske.c.
3832 This unfortunately causes incompatibilities with older
3833 clients and servers.
3835 * Added WIN32 specific network init and uninit functions:
3836 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3837 the Winsock2. Affected file lib/silcutil/silcnet.h and
3838 lib/silcutil/win32/silcwin32net.c.
3840 * Set the socket always to nonblocking mode on WIN32 after
3841 reading data or writing data. Affected file is
3842 lib/silcutil/win32/silcwin32sockconn.c.
3844 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3846 * Fixed various compilation problems under WIN32. Affected
3847 files lib/silcutil/win32/silcwin32thread.c and
3848 lib/silcutil/win32/silcwin32schedule.c.
3850 * Removed all _internal.h #includes from public header
3851 files. Internal headers must never be included from
3854 Removed also the lib/silcske/payload_internal.h file.
3856 * All include files that may be needed (public and some others
3857 included by the public headers) by application developers are
3858 now copied to the ./includes directory. It does not copy any
3859 internal headers. Affected file Makefile.defines.pre and all
3860 Makefile.am's under lib/ and subdirs.
3862 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3864 * Do not change the ~/.silc directory's permissions automatically.
3865 Affected file irssi/src/silc/core/clientutil.c.
3867 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3869 * Do not cancel the protocol in silc_server_close_connection
3870 it might cause recursion. Now cancelled in the function
3871 silc_server_free_sock_user_data. Affected file silcd/server.c.
3873 * Fixed the silc_server_remove_clients_by_server to regenerate
3874 the channel keys correctly finally. Added also new function
3875 silc_server_remove_clients_channels to actually do it.
3876 Affected file silcd/server.c.
3878 * Fixed the silc_server_new_channel to not crash by giving
3879 wrong router to the new channel. Affected file is
3880 silcd/packet_receive.c.
3882 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3884 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3885 which is given as argument to the silc_client_alloc now.
3886 It can be used to configure the client and set various parameters
3887 that affect the function of the client.
3889 * The USERS command in server did not check whether the channel
3890 is private or secret. Affected file silcd/command.c.
3892 * Added new argument to the USERS command in protocol specification.
3893 The USERS command now can take the channel name as argument
3894 as well. Added support for this in client and server and
3895 updated the protocol specs.
3897 * Completed the GETKEY command in client. It can be now used
3898 to fetch also servers public key not only some clients.
3899 Affected files lib/silcclient/command[_reply].c.
3901 * Added silc_client_get_server to return server entry by the
3902 server name. Affected files lib/silcclient/silcapi.h and
3905 * Redefined the IDENTIFY command in protocol specification to be
3906 more generic. It now can be used to query information about
3907 any entity in the SILC Network, including clients, servers and
3908 channels. The query may be based either the entity's name
3909 or the ID. Added support for this in both client and server.
3911 Affected files silcd/command.c and lib/silcclient/command.c
3912 and command_reply.c.
3914 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3915 the _from_client and _from_server functions. Affected file
3918 * Added silc_client_get_channel_by_id_resolve to the file
3919 lib/silcclient/silcapi.h to resolve channel information by
3920 its ID. Added also silc_client_get_channel_by_id that
3921 does not resolve it from the server.
3923 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3925 * Added SilcServerEntry context into the client library
3926 to represent one server. The INFO command now allocates
3927 these to save the resolved server info. For now on the
3928 client library will also keep information about servers,
3929 connected and resolved with INFO.
3931 The INFO command now allocates the SilcServerEntry context
3932 and saves the server info there. The COMMAND_REPLY in
3933 the INFO now returns the parameters to application in
3934 same order as defined in the protocol specification.
3936 The entries are cached in the client->server_cache.
3938 * The INFO command is now issued after received the Client ID
3939 from the server. Affected file lib/silcclient/client.c.
3941 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3942 to the application as the mode changer might be server.
3943 It is guaranteed that NULL is not returned anymore to the
3944 application. Affected file lib/silcclient/client_notify.c.
3946 The ID Type is now also passed to the application so that
3947 it can check whether the returned entry is SilcClientEntry
3950 Added new function silc_client_get_server_by_id to return
3951 the server entry by ID. Affected files are the
3952 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3954 * Do not create the channel in the Irssi SILC Client when issuing
3955 the JOIN command but when received the sucessful JOIN command
3956 reply. Otherwise the channel might get created even though we
3957 could not join it. The Affected file is
3958 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3960 * Fixed a channel joining bug in router. The router must also
3961 check the channel modes, invite and ban lists etc. when serving
3962 the JOIN command sent by normal server. Affected file is
3963 silcd/command.c. The router now resolves the client's
3964 information from the server who sent the JOIN command if it
3965 does not know it, and processes the JOIN command only after
3968 * Changed the SilcCommandCb to take new argument; void *context2.
3969 Affected file lib/silccore/silccommand.h
3971 The second argument in the command callbacks in the server now
3972 includes the SilcServerCommandReplyContext if the command was
3973 called as pending command callback from the command reply.
3974 Otherwise it is NULL. When called as pending the status of the
3975 command reply will be checked and if it was erronous the
3976 error will be sent to the original sender of the command.
3977 This way the client always receives the error messages even
3978 though the server was actually the one who received the error
3979 when it resent the command to router, for example. Affected
3980 files silcd/command[_reply].[ch].
3982 * Fixed sending WHOWAS command's error message to client if
3983 the requested client could not be found. It was missing.
3986 * Changed the CMODE and CUMODE commands reply arguments in the
3987 protocol specification. The Channel ID is now sent in both
3988 of the commands to identify the channel. Implemented this
3989 new feature to the client and server. Affected files
3990 lib/silcclient/command_reply.c and silcd/command.c.
3992 * Made better checks for invite and ban lists in the JOIN
3993 command in server. Affected file silcd/command.c.
3995 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3997 * The server now performs the incoming host IP/DNS lookup
3998 using the silc_socket_host_lookup and thus does not block
3999 the server anymore. Affected file silcd/server.c.
4001 * Completed the multi-thread support for SILC Scheduler in
4002 the lib/silcutil/silcschedule.c.
4004 * Fixed the configure.in.pre to detect the pthread correctly
4007 * Fixed a deadlock in silc_task_queue_wakeup in the file
4008 lib/silcutil/silctask.c.
4010 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4012 * Added new function silc_schedule_wakeup that is used in
4013 multi-threaded environment to wakeup the main thread's
4014 schduler. It needs to be used when a thread adds a new task
4015 or removes a task from task queues. After waking up, the
4016 scheduler will detect the task queue changes. If threads
4017 support is not compiled in this function has no effect.
4018 Implemented the wakeup mechanism to both Unix and WIN32
4019 systems. Affected files are lib/silcutil/silcschedule.[ch],
4020 lib/silcutil/unix/silcunixschedule.c and the
4021 lib/silcutil/win32/silcwin32schedule.c.
4023 * Added new function silc_task_queue_wakeup to wakeup the
4024 scheduler by the specified task queue. Affected file
4025 lib/silcutil/silctask.[ch].
4027 * The silc_socket_host_lookup_start now wakes up the scheduler
4028 after adding the timeout task. Affected file is
4029 lib/silcutil/silcsockconn.c.
4031 * The silc_socket_host_lookup is synchronous now if the threads
4032 support is not compiled in. However, the callback is still
4033 called asyncronously through the scheduler, anyway. Affected
4034 file lib/silcutil/silcsockconn.c.
4036 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4038 * Added new function silc_socket_host_lookup to perform
4039 asynchronous IP and FQDN lookups for the socket connection.
4040 Affected files lib/silcutil/silcsockconn.[ch].
4042 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4044 * Added SILC_MUTEX_DEFINE to define the mutex on environments
4045 that may or may not compile the mutex support in.
4047 Changed the silc_mutex_alloc interface. It allocates the
4048 mutex now to the sent pointer and returns TRUE or FALSE.
4050 Affected file lib/silcutil/silcmutex.h.
4052 * Wrote the SILC Task Queue interface to support multi-threads.
4053 Affected file lib/silcutil/silctask.[ch].
4055 * Wrote the SILC Scheduler to support multi-threads. Affected
4056 file lib/silcutil/silcschedule.c.
4058 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4060 * Implemented the SILC Mutex API and SILC Thread API for WIN32
4061 in lib/silcutil/win32/.
4063 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4065 * Defined SILC Mutex API and SILC Thread API and implemented
4066 them for Unix. Affected files are
4067 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
4068 lib/silcutil/unix/silcunixmutex.c and
4069 lib/silcutil/unix/silcunixthread.c.
4071 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4073 * Fixed the silc_server_remove_clients_by_server's channel
4074 key re-generation. The hash table handling was incorrect
4075 and would not work with many channels. Affected file is
4078 * Fixed some memory leaks around the server code.
4080 * Rewrote the silc_server_get_users_on_channel to support IPv6
4081 based Client ID's. Affected file silcd/server.c.
4083 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
4084 specification. However, a separate document must be written
4085 to define the detailed signing procedure and the payload
4086 associated with the flag. Defined the flag to the
4087 lib/silccore/silcchannel.h as well.
4089 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4091 * Changed the dynamic tables to static size tables in the
4092 lib/silccrypt/silchmac.c.
4094 * Removed GCC dependencies from the code. A patch by cras.
4096 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4098 * Do not show the error "Error receiving packet bla bla"
4099 in server if it really was not an error (-2 means that reading
4100 is pending). Affected file silcd/server.c.
4102 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4104 * Fixed a possible crash in silc_server_remove_clients_by_server
4105 in silcd/server.c. Fixed there also some memory leaks.
4107 * Fixed the silc_idlist_replace_client_id. It could replace
4108 wrong key in the hash table. Affected file silcd/idlist.c.
4110 * Do not check whether there are global users on the channel
4111 if the channel->global_users is FALSE. Affected functions
4112 silc_server_remove_from_one_channel and
4113 silc_server_remove_from_channels in silcd/server.c. Also,
4114 do not check if the removed client is local as we can be
4115 sure that global client was not removed from the channel
4116 and checking for global users is not needed.
4118 * The silc_server_remove_clients_by_server now re-generates
4119 the channel keys correctly for those channels that had
4120 clients removed from them. Affected file silcd/server.c.
4122 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4124 * Found the reason of random crashes in the server. We weren't
4125 ignoring the SIGPIPE signal (which can be sent in write())
4126 and it crashed the server. Affected file silcd/silcd.c.
4128 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4130 * Assure that sock->user_data is not NULL in the function
4131 silc_server_packet_send in silcd/packet_send.c.
4133 * Disconnect the remote connection if it could not be added
4134 to any ID lists in the server. The affected file is
4137 * Check in silc_server_packet_send[_real/dest] that the
4138 socket is not disconnecting and ignore the data if it is.
4139 Affected file silcd/packet_send.c.
4141 * Define inline to __inline on native WIN32 compilation.
4142 Affected file includes/silcwin32.h.
4144 * Added some explicit type casts for inline code since MSVC
4145 require them. Affected files lib/silcutil/silcbuffer.h,
4146 lib/trq/silcdlist.h and lib/trq/silclist.h.
4148 * Print warning in log files from now on if the packet
4149 decryption fails. Affected file silcd/server.c.
4151 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4153 * Changed the `say' client operation's interface to accept
4154 new `type' argument to indicate the type of the message sent
4155 by the library. The application may filter the library's
4156 messages according the type. The affected file is the
4157 lib/silcclient/silcapi.h.
4159 * Added two new functions to lib/silcclient/silcapi.h:
4160 silc_client_del_client and silc_client_del_client_by_id.
4161 Affected file lib/silcclient/idlist.c.
4163 * Moved the clientincludes.h from includes/ to silc/ and
4164 serverincludes.h from includes/ to silcd/.
4166 * The modes for the CMODE and CUMODE are now passed as
4167 uint32 for application with COMMAND_REPLY. The affected
4168 file is lib/silcclient/command_reply.c.
4170 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4172 * /WHOIS without arguments shows client's own information.
4173 Affected file lib/silcclient/command.c.
4175 * Changed PING to not accept any arguments. The specs
4176 says that client can ping only the connected server so
4177 requiring an argument is not needed. Affected file is
4178 lib/silcclient/command.c.
4180 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4182 * Fixed a fatal bug in private message sending and reception
4183 encryption and decryption when using private message keys.
4184 The implementation was incorrect and did not follow the
4185 specification. It causd that some of the message were
4186 lost since it did not use the sending and receiving keys
4187 as the protocol suggests. This has been fixed and will cause
4188 incompatibilities with older clients when sending private
4189 message encrypted with private message keys. Affected files
4190 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
4191 and various other in Irssi SILC Client.
4193 Added `responder' boolean argument to the functions
4194 silc_client_add_private_message_key[_ske] to indicate when
4195 the key is added as responder or initiator of the key
4198 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4200 * Removed the silc_ske_check_version function and created
4201 a SilcSKECheckVersion callback. Added also a function
4202 silc_ske_set_callbacks that is now used to set all SKE
4203 callbacks. The callback functions are not given to
4204 the SKE functions anymore, but this function is used to
4207 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
4209 * Added `silc_version' argument to the silc_client_alloc
4210 to define the version of the application for the library.
4211 The library will use the version string to compare it
4212 against the remote host's (usually a server) version
4213 string. Affected file lib/silcclient/silcapi.h
4215 * Added the KE protocol context to Key Agreement context
4216 in client library so that we can abort the SKE if it
4217 is in process when we get timeout. Affected file is
4218 lib/silcclient/client_keyagr.c.
4220 * Do not resolve the client ID forever if it returns in the
4221 first time that such client does not exist. This was done
4222 for example with private message. Affected file is
4223 lib/silcclient/client_prvmsg.c.
4225 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4227 * Do not add regex.h for WIN32. The affected file
4228 includes/silcincludes.h.
4230 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
4231 not work yet 100%. It generates the DLL's automatically
4232 when compiling with --with-win32 under cygwin.
4234 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4236 * lib/contrib/regex.c is not compiled on WIN32.
4238 * Added silc_net_get_socket_opt function to the
4239 lib/silcutil/silcnet.h.
4241 * Added includes/silcwin32.h for WIN32 specific includes
4244 * Do not use ptime structure or any of the posix process
4245 functions on WIN32 in lib/silccrypt/silrng.c.
4247 * Added silc_gettimeofday to provide generic function
4248 for struct timeval on all platforms. Added the function
4249 to lib/silcutil/silcutil.h.
4251 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4253 * Moved the lib/silccore/silcsockconn.[ch] to the utility
4254 library as they clearly belong there. As a plus side we
4255 can make the actual socket connection routines platform
4258 Added also new generic function silc_socket_read and
4259 silc_socket_write (that used to be silc_packet_[read/write].
4260 The implementation of these are platform specific.
4262 * Added WIN32 specific routines of silc_socket_[read/write]
4263 to lib/silcutil/win32/silcwin32sockconn.c.
4265 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4267 * Added preliminary support for native WIN32 compilation under
4268 cygwin (using the -mno-cygwin option for GCC) to the
4269 ./configure.in.pre. The --with-win32 now prepares the
4270 compilation for native WIN32.
4272 * Rewrote the SILC Scheduler interface in the file
4273 lib/silcutil/silcschedule.h. The scheduler is now context
4274 based and does not have anymore any global static scheduler.
4275 Moved the Unix scheduler to the lib/silcutil/unix/ directory
4276 and created lib/silcutil/win32 directory for WIN32 based
4279 * Added Unix specific network routines to the
4280 lib/silcutil/unix/silcunixnet.c and the old
4281 lib/silcutil/silcnet.c includes now only generic routines.
4283 Added WIN32 specific network routines to the
4284 lib/silcutil/win32/silcwin32net.c.
4286 * Added Unix specific utility functions from the
4287 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
4289 * Added WIN32 SILC Scheduler to the file
4290 lib/silcutil/win32/silcwin32schedule.c. The code is of course
4293 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4295 * Do not handle JOIN notify in the server if the target client
4296 is not registered (idata->registered == FALSE). The affected
4297 file is silcd/packet_receive.c.
4299 * Update the nickrec->founder in event_cumode in the Irssi SILC
4300 client. Affected file irssi/src/silc/core/silc-channels.c.
4302 * Fixed the CUMODE_CHANGE notify handling in the server when
4303 server and router are announcing their clients on channels.
4304 Now the mode changes are saved and notified correctly. The
4305 affected file is /silcd/packet_receive.c.
4307 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
4308 They really did not replace the cache entry in the ID Cache.
4309 Now they do that. Affected file silcd/idlist.c.
4311 * Fixed the KICK notify handling in the Irssi SILC client to
4312 update the channel records so that the kicked client does not
4313 appear to be on the channel. The affected file is
4314 irssi/src/silc/core/silc-channels.c.
4316 * Always update the conn->current_channel when executing command
4317 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
4319 * Fixed the KILL notify handling in Irssi SILC client to remove
4320 the killed client on all channels.
4322 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4324 * Fixed the silc_parse_command_line to remove extra spaces
4325 from the start and end of the arguments. Affected file is
4326 lib/silcutil/silcutil.c.
4328 * Cancel and free any active protocol in the function
4329 silc_server_close_connection. Affected file silcd/server.c.
4331 * Cancel and free any active protocol in the function
4332 silc_client_close_connction. Affected file is
4333 lib/silcclient/client.c.
4335 * Do not execute the KILL command for clients that are in
4336 history (ie. they are not in the network). Affected file is
4339 * Fixed KILL notify handling, client does not crash anymore.
4340 Affected file irssi/src/silc/core/silc-channels.c.
4342 * Reduced the default packet buffer size from 2048 to 1024 in
4343 lib/silccore/silcpacket.c.
4345 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
4346 counter to the SKE context that is incresed when the SKE library
4347 performs async operation outside the library. If the outside
4348 process frees the SKE context and FREED status will be set
4349 and the library will detect after the sync operation that the
4350 libary is freed. The affected files are
4351 lib/silcske/silcske[_status].[ch].
4353 * Resolve the client entry information in the function
4354 silc_client_channel_message to assure that NULL pointer is not
4355 passed as client entry to the application. */
4357 * Fixed the task timeout calculation to assure that there is
4358 never negative timeouts. The affected file is
4359 lib/silcutil/silcschedule.c.
4361 * Fixed the channel user mode notification sending in server.
4362 It was sent point-to-point to the router (or to server by router)
4363 but it needs to be destined to a channel. The routines now
4364 supports sending the channel user mode notifys to the channels
4365 when announcing clients and channels. Affected files are
4366 silcd/server.c and silcd/packet_receive.c.
4368 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
4369 It did not actually replace the old channel entry in the cache.
4370 Affected file lib/silcclient/client_notify.c.
4372 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4374 * Fixed a possible crash in silc_packet_send_prepare. It now
4375 assures always that there is enough space in the buffer and
4376 at the tail area of the buffer (for MAC).
4378 Fixed the inbound buffer reallocation in silc_packet_read.
4379 It was old code and did not handle the reallocation correctly.
4382 The affected file is lib/silccore/silcpacket.c.
4384 * Fixed buffer overflow in silc_parse_nickname in the file
4385 lib/silcutil/silcutil.c.
4387 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4389 * make install generates new server keys only if there is not
4392 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4394 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
4395 Added check that if the NOREPLY is set then we will not send
4396 the away message. This avoids infinite loop of away messages
4397 if both clients are away. The affected file is
4398 lib/silcclient/client_prvmsg.c.
4400 * Fixed client crash if /NICK was given without arguments.
4401 Affected file lib/silcclient/command.c.
4403 * Server does not send the invite list in INVITE command back
4404 to the client if the list was not altered. Added this notion
4405 to the protocol spec as well. Affected file silcd/command.c.
4407 Fixed possible crash in INVITE command by checking the
4408 value of silc_server_get_client_route command.
4410 * Fixed the INVITE notify type handling. The arguments are now
4411 taken in correct order and client does not crash. The affected
4412 file is irssi/src/silc/core/silc-channels.c.
4414 Removed the "Inviting xxx to channel" message from the
4415 client library away and let the application handle it.
4416 Affected file lib/silcclient/command.c. Added that message
4417 to Irssi SILC client's message formats.
4419 * Fixed CMODE command crash in client. It now checks the
4420 amount of arguments correctly and does not crash. The affected
4421 file is lib/silcclient/command.c.
4423 * Do not create new channel automatically in silc_channels_join
4424 but check whether the channel by that name already exists.
4425 Affected file irssi/silc/core/silc-channels.c.
4427 * Do not send the SERVER_SIGNOFF to router if the disconnected
4428 entity was the router. Affected file silcd/server.c.
4430 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
4431 SILC client as it was missing from there.
4433 Added the handling of the KICK notify to the Irssi SILC client
4434 as it was missing. Added "you have been kicked" message to
4435 Irssi SILC client's message modules formats.
4437 Added the handing of the KILL notify to the Irssi SILC client
4438 as it was missing. Added the kill message module formats
4441 The affected file is irssi/src/silc/core/silc-channels.c.
4443 * The router did not save the channel mode the server announced.
4444 Affected file silcd/packet_receive.c.
4446 * Fixed a possible crash in INFO command in server. If the
4447 server did not provide the server info it crashed. Affected
4448 file silcd/command.c.
4450 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4452 * Fixed the GETKEY command in the server to check also the
4453 global list. Otherwise the GETKEY would not work correctly
4454 in normal SILC server. Affected file silcd/command.c.
4456 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4458 * Fixed GETKEY crash, it crashed if the command did not succseed.
4460 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4462 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
4463 is now real and not just an macro interface to GMP.
4465 Removed the entire GMP from the source tree and imported new
4466 NSS MPI library instead. Reason for removing GMP is that it is
4467 extremely large and compiles extremely slow. The NSS MPI
4468 is only a few files and compiles in less than 10 seconds.
4469 The speed is also about the same as GMP. The MPI is imported
4470 to lib/silcmath/mpi.
4472 If the system has GMP installed we will still use the GMP.
4473 If it is not then the NSS MPI will be compiled.
4475 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4477 * Merged a long nickname (127 characters long) crash bugfix from
4478 Irssi CVS tree. Affected file irssi/src/core/misc.c.
4480 * Merged a freed memory reference bugfix from Irssi CVS tree.
4481 Affected file irssi/src/core/commands.c.
4483 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4485 * Added the server's public key sving and verification to the
4486 server when performing the SKE. This was missing and the
4487 remote server's (or router's) public key was accepted without
4488 checking whether we have it previously or trust it at all.
4489 Affected file silcd/protocol.c.
4491 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4493 * Check in the silc_server_timeout_remote if protocol is active
4494 and make sure that the protocol's final callback is called so
4495 that all memory if freed. Affected file silcd/server.c.
4497 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4499 * silc_server_whois_send_reply crashed the server if the nickname
4500 was 127 characters long. Affected file silcd/command.c.
4502 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4504 * Added sanity check to the silc_server_new_client. If the hostname
4505 is provided inside username then check that the provided hostname
4506 really is the same as the resolved one. If the hostname was not
4507 resolved then check it from the public key. Affected file is
4508 silcd/packet_receive.c.
4510 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
4511 if the server disconnected us and the connection is not valid
4512 anymore. Affected file irssi/src/silc/core/silc-channels.c.
4514 * Moved the silc_client_[chmode|chumode|chumode_char] away from
4515 the library to the lib/silcutil/silcutil.[ch].
4517 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4519 * Close log file after open. Affected file
4520 lib/silcutil/silclog.c.
4522 * Check whether sock == NULL in silc_client_send_packet and return
4523 if it is. Affected file lib/silcclient/silcclient.c.
4525 * Check rec->entry == NULL in the Irssi SILC Client before
4526 sending the channel message. Affecte file is
4527 irssi/src/silc/core/silc-servers.c.
4529 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4531 * Merged a splitted window bugfix from Irssi CVS tree. The
4532 affected file is irssi/src/fe-text/textbuffer-view.c.
4534 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
4535 It did not print nickname.
4537 * Improved the distributions system a bit.
4539 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4541 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
4542 irssi/src/fe-text/gui-window.c.
4544 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
4545 to in-active server. The affected file is
4546 irssi/src/silc/core/client_ops.c.
4548 * Resolve the client in USERS command reply if the entry does
4549 not have username resolved. The affected file is
4550 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
4551 command to WHOIS command to really resolve stuff. The USERS
4552 is not used any more in any critical section so WHOIS can
4553 be used even though it might be slower than IDENTIFY.
4555 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
4558 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4560 * Changed the protocol API a bit more consistent in the
4561 lib/silccore/silcprotocol.[ch].
4563 * Changed the following headers to ROBODoc format:
4565 lib/silccore/silcpayload.h
4566 lib/silccore/silcprotocol.h
4567 lib/silccore/silcsockconn.h
4569 All core library headers are now formatted.
4571 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4573 * Fixed a bug in Irssi SILC client; do not show that you are
4574 server/router operator if you really are not. Affected file is
4575 irssi/src/silc/core/client_ops.c.
4577 * Renamed silc_command_free_payload to silc_command_payload_free.
4578 Affected file lib/silccore/silccommand.h
4580 * Added silcmath.h to include the prototoypes of various routines
4581 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
4584 * Changed the following headers to ROBODoc format:
4586 lib/silccore/silcchannel.h
4587 lib/silccore/silccommand.h
4588 lib/silccore/silcid.h
4589 lib/silccore/silcidcache.h
4590 lib/silccore/silcmode.h
4591 lib/silccore/silcnotify.h
4592 lib/silccore/silcpacket.h
4593 lib/silcmath/silcmath.h
4595 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4597 * Added checking to the server code not to start the server if
4598 ciphers and stuff are not configured properly. Affected files
4599 silcd/serverconfig.[h] and silcd/server.c.
4601 * Changed the layout of the header files of the public interfaces
4602 in the SILC libraries. The new layout supports ROBODoc
4603 documentation tool (and some others) so that it is easy to create
4604 a library reference manual. All the other headers and source
4605 code must still follow the CodingStyle document. Also source
4606 code must not include these ROBODoc stuffs, only the headers.
4607 Furthermore, all public interface headers must now be named
4608 by using `silc' prefix, example: silcapi.h, silccipher.h.
4609 Some files were renamed due to this. All the other headers
4610 must not be used as public interfaces. I will update the
4611 CodingStyle document later. Changed following headers, so far:
4613 lib/silcclient/silcapi.h
4614 lib/silccore/silcauth.h
4615 lib/silccore/silcprivate.h
4616 lib/silccrypt/silcdh.h
4618 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4622 * Removed silc_client_packet_send_flush from the client library
4623 as it is not needed. Affected file lib/silcclient/client.[ch].
4625 * Added printing of message of unresolved authentication method
4626 to the Irssi SILC client. Added it to the module formats.
4627 Removed the same message from the client library.
4629 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4631 * Added new distribution feature, DISTLABEL. Every distribution
4632 can define own preprocessor label that can be used in the
4633 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
4634 file distributions, acconfig.h.pre and prepare.
4636 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4638 * Added Makefile.defines_int to include the actual definitions
4639 for Makefile.defines.in. Tested the new distribution system,
4640 created distributions and tested installation.
4642 * Added AWAY message printing to the Irssi SILC client. Added
4643 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
4645 * Added SCONNECT command to call the SILC's CONNECT command.
4646 Cannot use CONNECT directly since Irssi uses that internally.
4647 Affected file irssi/src/silc/core/silc-servers.c.
4649 Added ACTION local command. It is same as ME command but takes
4650 the channel as mandatory argument.
4652 Rewrote some of the Irssi's help files to suite for SILC
4655 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4657 * Added Makefile.defines[.in] that should for now on be included
4658 in all Makefile.am file in the source tree. That file includes
4659 all common compilation definitions for SILC source tree.
4661 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4663 * Minor changes to the ./prepare script to change the package
4664 name according the distribution name to the configure.in.
4666 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4668 * Created new distribution system. Added file `distributions'
4669 that defines all the distributions that can be created out of
4670 the SILC source tree. The ./prepare script now reads that
4671 file to determine how to prepare the distributions. The
4672 first argument to the ./prepare is the name of the distribution
4673 and second is the version of the distribution. If given
4674 without arguments it creates the default (toolkit) distribution
4675 with the default version (defined in ./prepare).
4677 All Makefile.am files that are subject to the distributions
4678 are now named as Makefile.am.pre. These are ./Makefile.am
4679 and lib/Makefile.am. Others may be changed later.
4681 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4683 * Added invite list, ban list, some key management and connection
4684 error message printing to module formats in the Irssi SILC client.
4686 * Added new silc_client_set_away_message to set the away message
4687 that is back to the person who sent private message. The
4688 affected file lib/silcclient/silcapi.h and the
4689 lib/silcclient/client_prvmsg.c.
4691 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4693 * Fixed the private message sending in the Irssi SILC client,
4694 added local command KEY to the Irssi SILC client.
4696 Added key management and key agreement message formats to the
4697 irssi/src/fe-common/silc/module-formats.[ch].
4699 Added USERS (alias WHO) printing, server/router operator
4700 indication and LIST command printing to the module formats.
4702 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4704 * Fixed channel joining notify handling, cumode notify handling
4705 from Irssi SILC client.
4707 * Added SILC specific module-formats to the Irssi SILC client so
4708 that SILC specific message hilighting, colors etc is possible.
4709 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4711 Added channel mode, channel user mode, actions, notices,
4712 whois and whowas printing to the the module-formats.c.
4714 * Fixed a bug in channel deletion in the server. The channel
4715 is not left to the cache even if the channel founder auth mode
4716 is set when there are no users anymore on the channel. Affected
4717 file silcd/server.c.
4719 * The silc_net_localhost now resolves the entire hostname including
4720 the domain name. Affected file lib/silcutil/silcnet.c.
4722 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4724 * Changed the ask_passphrase client operation to be ascynchronous.
4725 It has now a completion callback and a context that the
4726 application must call after it has got the passphrase from
4727 the user. Affected files lib/silcclient/silcapi.h,
4728 lib/silcclient/protocol.c, lib/silcclient/command.c and
4731 Added SilcAskPassphrase callback that the application calls
4732 to deliver the passphrase to the library.
4734 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4735 The public key verification and especially a certificate
4736 verification is asynchronous procedure.
4738 Added new SILC_SKE_STATUS_PENDING status to indicate the
4739 request is pending and a callback will be called to finalize
4742 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4743 indicate that remote end did not send its public key (or
4744 certificate), even though we require it. Added check for this
4745 condition in the SKE. This was a security bug, now fixed.
4747 Defined new SilcSKEVerifyCbCompletion callback that is called
4748 when the verification process is completed.
4750 The affected files lib/silcske/silcske_status.h and
4751 lib/silcske/silcske.[ch].
4753 * Changed the verify_public_key client operation to be async
4754 as well. Defined SilcVerifyPublicKey callback that is used to
4755 indicate the success of the public key verification process.
4757 Changed the server and client to use the new async client
4760 * Changed the Irssi SILC client's internal scheduler to be called
4761 twice as many times as it used to be. As a result the client
4762 should be a bit faster now. Affected file is
4763 irssi/src/silc/core/silc-core.c.
4765 * Added support to Irssi SILC client of asynchronous public key
4766 verification and passphrase inquiry. Affected file is
4767 irssi/src/silc/core/silc-core.c.
4769 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4771 * Do not say "You have left channel %s" in client library.
4772 Moved it to the application. Affected files are
4773 lib/silcclient/command.c and silc/client_ops.c.
4775 * Fixed silc_client_get_clients. Command context was not
4776 duplicated and was freed memory in the callback. Affected
4777 file lib/silcclient/idlist.c.
4779 * Do not say "you are now talking..." on JOIN command in the
4780 client library. The appliation must handle it.
4782 * Do not say ".. changed topic to" in command reply in the
4783 client libary. The application must handle it.
4785 * Fixed TOPIC command sending in the client library.
4787 * Fixed a memory leak in silc_client_command_free in the file
4788 lib/silcclient/command.c.
4790 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4792 * Imported a modified version of Irssi client to the source tree.
4793 The Irssi will be used to create a new client called
4794 Irssi SILC. Imported to irssi/.
4796 Added silc_core_init_finish function to the Irssi. Affected
4797 file irssi/configure.in.
4799 A lot changes in the Makefile.ams around the irssi tree.
4801 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4803 * Do not rehash if the new size is same as the old size of the
4804 hash table, in the silc_hash_table_rehash*. The affected file
4805 lib/silcutil/silchashtable.c.
4807 * Replaced hash_table_del_by_context calls from the server
4808 (when channel->user_list and client->channels) to the
4809 hash_table_del as it is sufficient and faster.
4811 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4813 * Added silc_hash_table_list, silc_hash_table_get and the
4814 SilcHashTableList structure to provide an alternative way to
4815 traverse the hash table. The affected files are
4816 lib/silcutil/silchashtable.[ch].
4818 * Changed the server's idlist routines to use the hash table
4819 routines to optimize the code.
4821 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4823 * Replaced the client entry's `channel' list and channel entry's
4824 `user_list' list to hash tables for optimized lookup. Changed
4825 the code to use the hash table interface around the code.
4826 Affected file lib/silcd/idlist.[ch].
4828 * Added `auto_rehash' boolean argument to the function
4829 silc_hash_table_alloc to indicate whether the hash table should
4830 auto-rehash when it thinks is appropriate time. It will
4831 increase the hash table size if the there is twice as much
4832 entries in the table than the size of the table, and will
4833 decrease the size if there are twice as less entries than
4834 the size of the table.
4836 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4838 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4840 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4842 * silc_idcache_purge_by_context deletes the entry now by context
4843 as it is supposed to do. Affected file lib/silccore/idcache.c.
4845 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4846 client is not anymore valid (WHOWAS givens the info) and not
4847 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4849 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4851 * Removed the `data' and `data_len' arguments from the ID Cache
4852 interfaces and added `name' argument. ID Cache does not handle
4853 anymore the binary data only a names associated with given ID.
4855 * When hashing a Client ID with silc_hash_id the entire ID is
4856 not hashed anymore, instead only the hash of the Client ID is
4857 hashed. This way we can access the Client ID from the cache
4858 with Client ID but with the hash of the ID (which is a hash of
4859 the nickname) as well without any difference in performance.
4861 Added also silc_idcache_find_by_id_one_ext to do one on one
4862 searching when we have the actual ID. Added also function
4863 silc_hash_client_id_compare. The affected files are
4864 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4866 * When hashing the name associated with a ID it is always done
4867 in lowercase. This way we can access the cache without worrying
4868 about case-sensitivity, even though, for example nicknames are
4871 * Fixed a bug in server with channel message sending. It put
4872 wrong ID type as destination ID. The affected file
4873 silcd/packet_send.c.
4875 * silc_idcache_del_by_context now deletes from all hash tables
4876 by context. Affected file lib/silccore/idcache.c.
4878 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4880 * Changed the client library to use the new ID Cache interface.
4881 Changes around the source tree.
4883 * Added silc_hash_table_rehash_ext to rehash with specific
4884 hash function. Affected file lib/silcutil/silchashtable.[ch].
4886 * Added silc_hash_string_compare to compare two strings in the
4887 hash table. Affected file lib/silcutil/silcutil.[ch].
4889 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4891 * Added new function silc_idcache_del_by_context into the
4892 lib/silccore/idcache.[ch].
4894 * Changed the server's ID list routines to use the new ID Cache
4895 interface. Changes around the source tree.
4897 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4899 * Added silc_hash_table_del[_by_context]_ext functions in to the
4900 lib/silcutil/silchashtable.[ch].
4902 Removed silc_hash_table_find_all* routines and added new
4903 silc_hash_table_find_foreach to replace them.
4905 Added silc_hash_table_replace_ext function as extended
4906 replacing function. Separated the simple hash table interface
4907 from the extended hash table interface in the file
4908 lib/silcutil/silchashtable.h.
4910 * Fixed minor bugs and changed it to use some of the new
4911 hash table functions in lib/silccore/idcache.c
4913 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4915 * Added new function silc_hash_table_find_all to return all keys
4916 in the hash table by the specified key. As the hash table is
4917 collision resistant it also makes it possible to have several
4918 duplicate keys in the hash table. This function may be used to
4919 find all of the keys from the hash.
4921 Added user_context arguments to the SilcHashFunction,
4922 SilcHashCompare and SilcHashDestructor to deliver user specified
4925 Added new fuctions silc_hash_table_find[_all]_ext to do
4926 extended lookup with specified hash and compare functions and
4927 specified user contexts.
4929 Added new function silc_hash_table_add_ext to add the key
4930 with specified hash function and user context.
4932 Added new function silc_hash_table_foreach to traverse all
4933 entrys in the hash table. Added SilcHashForeach callback
4936 Added new function silc_hash_table_del_by_context to delete
4937 the entry only if the context associated with the key matches.
4939 Affected files are lib/silcutil/silchashtable.[ch].
4941 * Removed silc_hash_[server/client/channel]_id and added just
4942 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4943 silc_hash_id_compare to compare two ID's using as the hash table
4944 comparison function. Added also silc_hash_data to hash
4945 binary data and silc_hash_data_compare to compare it.
4947 * Removed silc_idlist_find_client_by_hash as it is not needed
4948 anymore. Affected file silcd/idlist.[ch].
4950 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4951 to use internally the SilcHashTable. The new ID Cache is a lot
4952 faster than the old one. Some of the ID Cache interface was also
4953 rewritten and obsolete and stupid functions were removed.
4955 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4957 * Added entry_count field to the SilcHashTable to keep the number
4958 of the entries in the table. Implemented the function
4959 silc_hash_table_rehash. Added new function
4960 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4962 Fixed a minor bug in silc_hash_table_free.
4964 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4965 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4966 into the lib/silcutil/silcutil.[ch].
4968 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4970 * Implemented a collision resistant hash table into the
4971 lib/silcutil/silchashtable[ch]. See the header and the source
4972 for the SilcHashTable API.
4974 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4976 * Merged dotconf version 1.0.2 into lib/dotconf.
4978 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4980 * Do not compile anything in lib/silcsim/* if the SIM support
4981 is not enabled. The tree should now compile without problems
4984 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4986 * Compiled the SILC under cygwin. Compiled and tested briefly
4987 without problems. More tests needed. The SIMs didn't compile
4990 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4992 * Fixed possible crash in silc_get_username in the
4993 lib/silcutil/silcutil.c.
4995 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4997 * Fixed a va_arg in silc/client_ops.c.
4999 * Oops, RC5 routines were named AES and caused some problems
5000 when not using SIM's. Affected file lib/silccrypt/rc5.c.
5002 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5004 * Added new SilcIDIP structure into the lib/silccore/id.h and
5005 replaced the old `ip' fields from all SILC ID's to that type.
5006 This is a step towards IPv6 support.
5008 The silc_id_get_len takes now the ID as an extra argument.
5009 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
5010 both IPv4 and IPv6 based ID's.
5012 The affected files are lib/silccore/id.[ch] and other files
5013 around the tree using these routines.
5015 * Removed the ID length arguments in server from various
5016 silc_server_send_notify_* routines -> they are not needed
5019 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5021 * Fixed memory leak in silc_encode_pem_file in the file
5022 lib/silcutil/silcutil.c.
5024 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5026 * Check minor version as well in the SKE. Affected files are
5027 silcd/protocol.c and lib/silcclient/protocol.c.
5029 * Added --identifier option to the server so that an identifier
5030 can be when creating the public key for the server. Affected
5031 file is silcd/silcd.c.
5033 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
5034 lib/silccrypt/silcpkcs.c.
5036 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5038 * Register default ciphers and stuff when using -C option with
5039 the server. Affected file sildc/silcd.c.
5041 * Put back the servers public key filename format, it is better
5042 than the new one. For now, the client keys are saved with the
5043 new filename format. The affected file silc/client_ops.c.
5045 * Implemented the Cipher API for the rest of the ciphers that
5046 did not implement it or implemented it the wrong way.
5048 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5050 * Register default ciphers and stuff when using the -S option
5051 in the client. Affected file silc/silc.c. Same also when
5052 creating new key pair with -C option.
5054 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5056 * Fixed the silc_verify_public_key client operation function to
5057 save the public keys differently. The fingerprint is now
5058 used as filename and not the hostname. This way also the
5059 client keys are saved uniquely and not with hostnames. The
5060 affected file is silc/client_ops.c.
5062 * Trimmed the silc_hash_fingerprint function to remove extra
5063 whitespaces from the end of the fingerprint. The affected
5064 file is lib/silccrypt/silchash.c.
5068 * Added silc_cipher_register_default function to register all
5069 default ciphers. It can be used when configuration files
5070 does not exist and the application does not want any specific
5071 ciphers in any specific order.
5073 The SilcDList is now used as silc_cipher_list dynamically
5074 allocated cipher list. Removed the static list all together
5075 and now all ciphers must be allocated to the dynamic list.
5076 The silc_cipher_alloc routine was changed to check only the
5079 All silc_cipher_* routines that used to return int returns
5082 The affected files lib/silccrypt/silccrypt.[ch].
5084 * The same thing was done to silc_hash_* as for silc_cipher_*
5085 routines. Affected files lib/silccrypt/silchash.[ch].
5087 * The same thing was done to silc_pkcs_* as for silc_cipher_*
5088 routines. Affected files lib/silccrypt/silcpkcs.[ch].
5089 Added also silc_pkcs_[un]register[_default] functions.
5090 Removed the data_context from the PKCS API.
5092 * Added silc_hmac_register_default function to register default
5093 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
5094 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
5095 to unregister all hmacs at once.
5097 * Register the default ciphers, hash functions, PKCSs and HMACs
5098 if client's configuration file does not exist. The affected
5101 * The client did not load the hash functions from the SIM
5102 modules at all. Added support for this. Affected file is
5103 silc/clientconfig.c.
5105 * When decoding public key with silc_pkcs_public_key_decode, check
5106 the supported algorithm only if PKCS are registered. Affected
5107 file lib/silccrypt/silcpkcs.c. The same was done with the
5108 silc_pkcs_private_key_decode.
5110 * Fixed the SILC List routines to keep the list always in order.
5111 It used to change the list's order when traversing the list but
5112 not it preserves the order. Affected file lib/trq/silclist.h.
5114 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5116 * Added the client library to use the SilcSocketConnection's
5117 reference counter (by silc_socket_dup) to prevent the bug that
5118 the socket object may be freed underneath async operation.
5120 * The name resolv library checking fixes in the configure.in.pre.
5123 * Created new version of the protocol drafts for future
5124 development. The -03 drafts are the ones that will be changed
5125 in the trunk now and the -02 will remain as they are.
5127 * Send list of CUMODE notifys to the router when announcing
5128 the channel users to the router. Affected file silcd/server.c.
5129 If the router receiving channel founder CUMODE for a channel
5130 that already has channel founder it will send CUMODE notify
5131 to the sender to remove the channel founder rights from the
5132 announced client. Affected file silcd/packet_receive.c.
5134 * The CUMODE notify may now use Server ID as well as the entity
5135 who changes the mode. Updated protocool specs.
5137 * Updated INSTALL and README files.
5139 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5141 * New web pages in the http://silc.pspt.fi. The pages was
5146 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5148 * Implemented the [DenyConnectin] config section in the server.
5149 Added silc_server_config_denied_conn to check whether incoming
5150 connection is denied. Affected file silcd/serverconfig.[ch].
5152 * Do not check the ports when checking the incoming configuration
5153 data if the port is 0, meaning any. Affected file is
5154 silcd/serverconfig.c.
5156 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5158 * Fixed buffer overflow in silc_string_compare in the file
5159 lib/silcutil/silcutil.c.
5161 * Fixed double free in silc_server_command_leave in the file
5164 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5166 * Fixed the version checking in the server. Affected file is
5169 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5171 * Fixed the configuration data fetching when accepting new
5172 connections in the server. Affected file silcd/server.c.
5174 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5176 * Added `sender_entry' argument to the function
5177 silc_server_packet_relay_to_channel so that we can check
5178 whether some destination actually belongs to the same route
5179 the sender belongs (ie, we must not resend the packet to the
5180 sender). Affected file silcd/packet_send.[ch].
5182 * Added `servername' field to the SilcClientEntry in the server
5183 to hold the name of the server where client is from. Affected
5184 file is silcd/idlist.h.
5186 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5188 * Moved the channel message encrypting in the router betwen
5189 router connections from silc_server_channel_message to the
5190 silc_server_packet_relay_to_channel since we want to check
5191 whether we have anybody channel before encrypting anything.
5192 Affected files silcd/packet_[receive/send].c.
5194 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5196 * Fixed the [AdminConnection] server config section to support
5197 multiple entries. Affected file silcd/serverconfig.c.
5199 * Added support into the server to check the validity of the
5200 incoming connection before executing any KE or authentication
5203 * The connection configuration is now saved to the KE and
5204 connection auth protocol contexts and not fetched anymore in
5205 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
5207 * The local hosts listenning address and port is also resolved
5208 now when starting the server. We want to have the socket object
5209 to include the real address and port for the listener. Added
5210 new function silc_net_check_local_by_sock into the files
5211 lib/silcutil/silcnet.[ch].
5213 * Fixed a broadcast bug in server -> do not broadcast if we
5216 * Fixed a routing bug. Do not route broadcast packets ever.
5217 Broadcast packets must be processed always and not routed since
5218 they may be destined to some other host than yourself and thus
5219 would get routed without no good reason. Affected file is
5222 * Added function silc_server_config_is_primary_route to check
5223 whether primary router connection has been configured (a router
5224 configuration that we are initiating). If there is not, we
5225 will assume that there is only two routers in the SILC network
5226 and we will use the incoming router connection as our primary
5227 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
5229 * Changed the order of the broadcasting. Broadcast _after_ the
5230 packet has been processed not before. Affected file is
5233 * Fixed a [ClientConnection] parsing bug. The port was never
5234 parsed correctly thus resulting to port 0. Affected file
5235 silcd/serverconfig.c.
5237 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
5238 argument and did not set the broadcast packet flag. Affected
5239 file silcd/packet_send.c. Fixed same bug in the function
5240 silc_server_send_notify as well.
5242 * If we receive NEW_ID packet for our own ID in the server, ignore
5245 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5249 * Removed the nickname from the Private Message Payload.
5250 Updated the code and the protocol specs.
5252 * Updated protocol specs for submitting to the IETF.
5254 * Tweaked the Random Number Generator a bit. Affected file
5255 lib/silccrypt/silcrng.c. Exported a new function
5256 silc_rng_[global]_add_noise which can be used to add more
5259 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5261 * Do not parse packets with different timeout when protocol
5262 is active -> may cause problem with rekey. Affected file
5265 * When server receives signoff notify it must not create
5266 new channel key if the client is on any channels since the
5267 sender of the signoff notify will create it.
5269 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5271 * Added printing of error messages during SKE protocol from the
5272 failure packet sent by server during SKE. Affected file
5275 * Removed the client's failure_callback handling with timeout
5276 and handle it immediately when received.
5278 * The SKE library returned wrong type in SUCCESS and FAILURE
5279 packets. They must be 32 bit MSB not 16 bit MSB.
5281 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5283 * Ok, rewrote the logic of the re-key and now it seems to work.
5284 I tested it on high traffic with frequent re-keys without
5285 problems. Added hmac_receive (and renamed hmac to hmac_send)
5286 in SilcClientConnection in lib/silcclient/client.h and
5287 in SilcIDListData in silcd/idlist.h. Also, removed the
5288 SilcPacketParserContext's cipher and hmac fields as they are
5289 not needed anymore and actually caused some problems when
5290 the ciphers and hmac's changed underneath the packet parser.
5292 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5294 * If re-key protocol is active then process the incoming packets
5295 synchronously since we must assure that icoming packets encrypted
5296 with the old key is processed before the new keys is set to
5297 use. This is true other packets than for REKEY packets.
5298 Affected file silcd/server.c. The same was done to client library
5299 as well, affected file lib/silcclient/client.c.
5301 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5303 * Fixed bug in client and server to accept the force send if
5304 the packet is send from silc_[server/client]_packet_process
5305 function. Otherwise the packets are never delivered, oops.
5307 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5309 * Disable force sending of packets when REKEY protocol is active.
5310 We must assure that no packet is sent directly when rekey is
5311 performed. All packets must be sent through packet queue.
5312 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
5313 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
5314 function is silc_[server/client]_packet_send_real to check
5317 * Replaced the SIM paths from example config files to
5318 /usr/local/modules. Also, make install creates now
5319 /usr/local/silc/logs directory to hold all the SILC server
5322 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5324 * Made the configure.in.pre work on Solaris. Patch by salo.
5326 * Made all ciphers compatible with non-x86 machines. Defined
5327 CBC mode macros into lib/silccrypt/ciphers_def.h.
5329 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5331 * Fixed the make install.
5333 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5335 * When MAC computation fails the silc_packet_decrypt returned 0
5336 even though it was supposed to return -1. Fixed this. The
5337 affected file is lib/silccore/silcpacket.c.
5339 * Do not replace the config files in /etc/silc (in make install)
5340 if they already exist. Affected file ./Makefile.am.
5342 * Do not send re-key packets immediately but through packet queue.
5343 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
5345 * Changed silc_net_check_host_by_sock to return FALSE if the
5346 IP/DNS could not be resolved. Though, it returns the IP address
5347 now even if it could not resolve it (but returns also FALSE).
5348 Affected file lib/silcutil/silcnet.[ch].
5350 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5352 * Added silc_pkcs_decode_identifier to decode the public key's
5353 identifier. Affected file lib/silccrypt/silpkcs.[ch].
5354 Added also silc_pkcs_free_identifier. Added also new context
5355 SilcPublicKeyIdentifier.
5357 * Added -S option to the silc client. It is used to dump the
5358 contents of the specified public key file.
5360 * Changed the PKCS api to return the public key length when
5361 setting the public key.
5363 * Fixed a fatal bug in the public and private key file loading.
5364 Affected file lib/silccrypt/silcpkcs.c.
5366 * Execute the packet parsing for client with zero (0) timeout
5367 if the protocol is active. Affected file silcd/server.c.
5369 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5371 * Made the key generation options to the silcd program. Added
5372 -C option, equivalent to client's option.
5374 * Added new [ServerKeys] config section to the server. It
5375 configures the server's public and private key.
5377 * Defined generic Public Key Payload into the protocol
5378 specification to send specific type of public keys and
5381 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
5382 public key or certificate.
5384 * Implemented the GETKEY command to the server and to the
5385 client library and on user interface.
5387 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5389 * Made preliminary `make install' work.
5391 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5393 * Added SilcServerRekey context into silcd/idlist.h.
5395 * Added the PFS support as defined in the specification to the
5396 SKE protocol. Affected files lib/silcske/*.c.
5398 * Added `ske_group' field to the SilcServerRekey context to hold
5399 the number of the SKE group that is used with PFS in re-key.
5400 Affected file silcd/idlist.h.
5402 * Added PFS re-key support to the server. Affected file is
5405 * Added silc_protocol_cancel to cancel execution of the next
5406 state of the protocol. Affected file is
5407 lib/silccore/silcprotocol.[ch].
5409 * Added the re-key support with and without PFS to the client
5410 library. Re-key is performed once in an hour, by default.
5412 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
5413 Added silc_client_rekey_callback and silc_client_rekey_final.
5414 Affected files are lib/silcclient/protocol.[ch] and
5415 lib/silcclient/client.[ch].
5417 * Removed the `hmac_key' and `hmac_key_len' fields from the
5418 SilcClientConnection structure; not needed. Affected file is
5419 lib/silcclient/client.h.
5423 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5425 * Do not ask whether user wants to use the negotiated private key
5426 for private messages, just use it. Affected file is
5427 silc/local_command.c.
5429 * Added `send_enc_key' and `enc_key_len' fields to the
5430 SilcIDListData structure since they are needed in the re-key
5431 phase. Affected file is silcd/idlist.[ch].
5433 * Implemented the simple re-key protocol into the server.
5434 Affected files silcd/server.c and silcd/protocol.[ch]. The
5435 re-key will be performed once in an hour, by default.
5437 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
5438 Added silc_server_rekey, silc_server_rekey_callback and
5439 silc_server_rekey_final.
5441 * Removed Tunneled flag from the protocol. Updated the code
5442 and the specifications.
5444 * Adde `pfs' field to the SilcIDListData to indicate whether
5445 the PFS is to be performed in the re-key. Affected file is
5448 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5450 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
5451 int64 of at least the xintXX size. If void * is less that 4
5452 bytes uint32 * will be used. Defined bool as boolean.
5454 * Changed _ALL_ unsigned long and unsigned int to uint32,
5455 unsgined short to uint16 in the source tree.
5457 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
5458 not handle clients that has entry->data.registered == FALSE.
5459 They are not in the network anymore. Affected file is
5462 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5464 * Implemented the sending of the SERVER_SIGNOFF notify in the
5465 server. Affected file is silcd/server.c.
5467 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
5468 Added also silc_notify_payload_encode_args into the
5469 lib/silccore/silcnotify.[ch].
5471 * Implemented ther SERVER_SIGNOFF notify handling in the server.
5472 Affected file silcd/packet_receive.c.
5474 * Implemented the SERVER_SIGNOFF notify handling in the client
5475 library. Affected file lib/silcclient/client_notify.c. Also,
5476 implemnted the printing of the SERVER_SIGNOFF info to the
5477 application. Affected file silc/client_ops.c.
5479 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
5480 if the deleting was successful. Affected file silcd/idlist.[ch].
5482 * Added support for public key authentication in the connection
5483 authentication protocol in the client library. Affected file
5484 lib/silcclient/protocol.c.
5486 * Changed the server's silc_idlist_get_clients_by_* interface
5487 to support already allocated array so that new entries may be
5488 added to pre-allocated array. Affected file silcd/idlist.[ch].
5489 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
5490 and command replies.
5492 * All command reply functions in the server now calls the
5493 pending command callback even if error occured. This way the
5494 error will be delivered to the client as well. Affected files
5495 silcd/command.c and silcd/command_reply.c.
5497 * Fixed INFO command to return local server's info if no server
5498 was provided. Affected file lib/silcclient/command.c.
5500 * Removed RESTART command for good. Updated the code and the
5503 * Rewrote parts of the task system. It is a bit simpler now.
5504 Removed unsued task priorities. The affected files are
5505 lib/silcutil/silctask.[ch].
5507 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5509 * Moved the USERS printing from the library to the application.
5510 Affected files lib/silcclient/command.c and silc/client_ops.c.
5512 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5516 * Added channel key re-key support. The re-key is perfomed
5517 only by the router and is done once in an hour. Added `rekey'
5518 field to the SilcChannelEntry in the server. Affected files
5519 silcd/server.c and silcd/idlist.h.
5521 * Added silc_task_unregister_by_context into the file
5522 lib/silcutil/silctask.[ch].
5524 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5526 * Added SILC_UMODE_GONE mode to indicate when the client is not
5527 present in the SILC network. Added also support to the local
5528 command AWAY that will set this mode. Added support of showing
5529 "xxx is gone" in WHOIS command. The USERS command shows the
5530 gone status as well.
5532 * Fixed setting server and router operator privileges in the
5533 server's UMODE command. Affected file silcd/command.c.
5535 * Merged the SKE KE1 and KE2 payloads into one payload. The
5536 new KE payload is equivalent to the old KE2 payload.
5538 Cleaned up the SKE Start Payload parsing. It now uses the
5539 simple buffer unformatting to do the parsing. A lot faster
5542 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
5543 to the SKE that is used to indicate whether both of the SKE
5544 parties should perform authentication. By default only the
5545 responder performs authentication. By setting this flag also
5546 the initiator must do authentication. By default it is unset
5547 since in normal SKE case, client to server connection, only
5548 the responder should do authentication. When doing SKE between
5549 two clients both should perform authentication. Updated the
5550 code and the protocol specs.
5552 * A little fix to IDENTIFY command in the server. Search the
5553 client first by hash not nickname. Affected file is
5556 * Fixed the silc_client_close_connection to support closing
5557 the client to client connections wihtout deleting too much
5558 data. Affected file lib/silcclient/client.c.
5560 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
5561 are received if protocol used to be active but is not anymore
5562 the application would crash due to NULL pointer dereference.
5563 Affected files silcd/server.c and lib/silcclient/client.c.
5565 * Added `hash' field to the SilcClientConnection to include
5566 the hash function negotiated in the SKE protocol.
5568 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
5569 to set the channel founder authentication data. A client can
5570 claim the founder rights later by providing the authentication
5571 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
5572 This way the channel founder can regain the channel founder
5573 privileges even it is left the channel. This works only on
5574 local server and the client must be connected to the same
5575 server to be able to regain the founder rights. Updated the
5576 protocol specs accordingly.
5578 Added support to the CMODE command in the client to set the
5579 founder auth data. Read the README to see how to set it.
5581 Added support to the CUMODE command to claim the founder
5582 rights. Read the README to see how to do it.
5584 Added support for the founder authentication to the Channel
5585 Entry in the server. Affected file silcd/idlist.h.
5587 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
5588 server's CMODE command. Affected file silcd/command.c.
5590 * Added the following new functions into lib/silccore/silcauth.[ch]:
5591 silc_auth_get_method and silc_auth_get_data.
5593 * The server now saves the remote hosts public key to the
5594 SilcIDListData pointer. Affected file silcd/protocol.c.
5596 * The normal server now does not remove the channel entry from
5597 the cache if the founder authentication data is set. It used
5598 to remove it if the founder was the last one on the channel on
5599 the server and left the channel. The auth data is saved and
5600 if the channel is re-joined later the old entry is used with
5601 the old auth data. Affected files silcd/command_reply.c and
5604 * Removed the `pkcs' field from the SilcIDListData structure
5605 in the server; it is not used. Affected file silcd/idlist.h.
5607 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5609 * Fixed packet processing on slow links. Partial packets were
5610 never re-processed because the incoming data buffer was cleared
5611 by the application. Application must not directly clear the
5612 sock->inbuf, the packet processing routines handle it. Fixed
5613 this in client library and in server.
5615 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5617 * Fixed the WHOIS and IDENTIFY send reply function to really
5618 check whether to send list or just one entry. Affected file
5621 * Cleaned up the LEAVE command's channel key distribution. The
5622 affected file silcd/command.c.
5624 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
5625 can enforce the channel mode as well. In that case the ID
5626 includes the ID of the server. The code now enforces the
5627 mode change if the router have different mode than the server.
5629 * The notify client operation with CMODE_CHANGE notify can now
5630 return NULL client_entry pointer if the CMODE was not changed
5631 by client. Application must check for this.
5633 * Added <Server ID> argument to INFO command to support server
5634 info fetching by Server ID.
5636 * Added silc_server_announce_get_channel_users to get assembled
5637 packets of channel users of the specified channel. Affected
5638 file silcd/server.[ch].
5640 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
5641 was freed underneath the ID Cache.
5643 * Re-announce clients when the server received CHANNEL_CHANGE
5644 notify from the router. Affected file silcd/packet_send.c.
5646 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5648 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
5649 crashed since it did not handle the fact that there is no cipher
5650 called "3" and didn't check the error condition. Now fixed.
5652 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
5653 flag. It can be used to send message requests.
5655 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5657 * Implemented the RESTART command in the client.
5659 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
5660 notice type messages. Added notice printing to the user
5663 * The channel keys are not re-generated if the channel's mode
5664 is PRIVKEY, ie private key on the channel exists. Affected
5665 files silcd/server.c and silcd/command.c.
5667 * Fixed a little bug in channel message delivery when channel
5668 private keys are set in the server. Affected file is
5669 silcd/packet_send.c.
5671 * Changed the setting on channel->on_channel = TRUE from the
5672 silc_client_save_channel_key to the JOIN command reply. The
5673 key payload is not received if the private channel key is set.
5674 Affected file lib/silcclient/command_reply.c and the
5675 lib/silcclient/client_channel.c.
5677 * When the CMODE_CHANGE notify is sent and the channel private
5678 key mode is removed the channel key must be re-generated in
5679 other cells as well. Added this support for the router in the
5680 silcd/packet_receive.c.
5682 * Added new local command NOTICE to send notice message on
5683 channel. Affected file silc/local_command.[ch].
5685 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5687 * Added new local command ME to the client. It is used to send
5688 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
5689 some action. Affected file silc/local_command.[ch].
5691 * Changed channel_message and private_message client operations
5692 to deliver the message flags to the application. Added also
5693 the `flags' arguments to the silc_client_send_channel_message
5694 and silc_client_send_private_message functions. Affected file
5697 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5699 * Redefined the Private Message Payload to support private message
5700 keys and to support the new private message flags. Updated
5701 the protocol specs. Flags makes it possible to have for example
5702 CTCP style messages.
5704 * Added new type SilcPrivateMessagePayload and defined an API
5705 for it in the lib/silcclient/silcprivate.[ch].
5707 * Tested private message private keys successfully. Tested the
5708 private message key set, unset and list commands with the new
5711 * Redefined the Channel Message Payload to include the channel
5712 message flags (equal with private message flags) to support
5713 for example CTCP style messages.
5715 * Defined some of the message (for channel and private message)
5716 flags. Updated the protocol specs and added the flags to the
5717 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5719 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5721 * Added SilcKeyAgreementStatus type to the key agreement routines
5722 to indicate the current status and error if one occured.
5723 The status types are defined in the lib/silcclient/silcapi.h.
5725 * Added new local command KEY that is used to set and unset private
5726 keys for channels, set and unset private keys for private messages
5727 with remote clients and to send key agreement requests and
5728 negotiate the key agreement protocol with remote client. The
5729 key agreement is supported only to negotiate private message keys,
5730 it currently cannot be used to negotiate private keys for channels,
5731 as it is not convenient for that purpose.
5733 * Fixed a minor pending callback setting bug in the function
5734 silc_client_get_client_by_id_resolve, now the function works.
5735 Affected file lib/silcclient/idlist.c.
5737 * Added function silc_net_get_local_port to get local bound
5738 port by socket. Added to lib/silcutil/silcnet.[ch].
5740 * Added `sockets' and `sockets_count' fields to the SilcClient
5741 object. They hold the sockets of the listenning sockets in
5742 the client. Listenning sockets may be for example the key
5743 agreement server. Affected file lib/silcclient/client.[ch].
5744 Added functions the silc_client_add_socket and the
5745 silc_client_del_socket. They are exported to the application
5748 * Added ~./silc/clientkeys to support other client's public keys.
5750 * Renamed verify_server_key client operation to verify_public_key
5751 and added one argument to indicate the type of the connection
5752 (server, client etc.).
5754 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5756 * Added silc_server_connection_auth_request to handle the
5757 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5758 silcd/packet_receive.[ch].
5760 * Added silc_server_send_connection_auth_request into the
5761 silcd/packet_send.c to send the connection auth request packet.
5763 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5766 * Fixed the public key authentication in responder side in the
5767 server. The `auth_data' pointer includes the SilcPublicKey
5768 not the path to the public key. Affected file silcd/protocol.c.
5770 * Implemented the public key authentication in the initiator side
5771 in the server. Affected file silcd/protocol.c.
5773 * Removed the [RedirectClient] config section from the server
5774 configuration. Is not needed and I don't want to implement it.
5776 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5778 * Cleaned up the CMODE command in the server. It now works
5779 correctly and supports all the modes defined in the protocol.
5780 Affected file is silcd/command.c.
5782 * Added `hmac_name' field to the SilcChannelEntry in the server
5783 to hold the default HMAC of the channel. It can be set when
5784 creating the channel (with JOIN command). Affected files
5787 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5788 type to indicate the change of the current cipher and hmac
5789 on the channel. Client can safely ignore the <cipher> argument
5790 (if it chooses to do so) since the CHANNEL_KEY packet will
5791 force the channel key change anyway. The <hmac> argument is
5792 important since the client is responsible of setting the new
5793 HMAC and the hmac key into use.
5795 * Fixed the CMODE command in the client library as well.
5797 * Tested CMODE command in router environment successfully.
5799 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5801 * Show the version of the remote client (or server) when connecting
5802 to the server. It is logged to the log file. Affected file
5803 is silcd/protocol.c.
5805 * Fixed the KILLED notify handling in the client library. The
5806 client must be removed from all channels when receiving the
5809 Also, do not remove the client entry when giving the KILL
5810 command but when the KILLED notify is received.
5812 * Removed silc_idlist_find_client_by_nickname from the server.
5813 Not needed anymore. Affected files silcd/idlist.[ch].
5815 * Implemented the CHANNEL_CHANGE notify type handling to the
5816 server. Affected file silcd/server.c.
5820 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5822 * Added silc_server_send_notify_invite to send the INVITE
5823 notify between routers.
5825 * Implemented the INVITE command correctly to the server.
5827 * Implemented the INVITE notify type handling in the server.
5829 * Implemented the INVITE command to the client library and on the
5832 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5834 * Added function silc_server_get_client_resolve to find the
5835 client entry by ID from all ID lists and then resolve it
5836 (using WHOIS) if it cannot be found. Affected file is
5839 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5841 * Implemented the BAN command to the client library.
5843 * The JOIN command in the server now checks the invite list
5846 * Changed the silc_command_reply_payload_encode_va and the
5847 silc_command_payload_encode_va to support that if argument is
5848 NULL it ignores and checks the next argument. Affected file
5849 lib/silccore/silccommand.c.
5851 * Added silc_server_send_notify_ban to send the BAN notify
5852 type between routers.
5854 * Chaned the silc_notify_payload_encode to support that if
5855 argument is NULL it ignores and checks the next argument.
5856 Affected file lib/silccore/silcnotify.c.
5858 * Tested ban lists in router environment successfully.
5860 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5862 * Implemented BAN command to the server, in silcd/command.[ch].
5864 * Removed the BAN and INVITE_LIST modes from the CMODE command
5867 * Added function silc_string_match to regex match two strings.
5868 Affected files lib/silcutil/silcutil.[ch].
5870 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5872 * Redefined parts of the SilcChannelEntry in the server to support
5873 the new ban and invite lists.
5875 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5877 * Redefined the INVITE command. The same command can be used to
5878 invite individuals to the channel but also to manage the invite
5879 list of the channel (to add to and remove from the invite list).
5880 Updated the protocol specs.
5882 * Added new command SILC_COMMAND_BAN that can be used to manage
5883 the ban list of the channel. Updated the protocol specs.
5885 * Removed the channel modes: the SILC_CMODE_BAN and the
5886 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5887 in the CMODE command. The equivalent features are now available
5888 using INVITE and BAN commands. Updated the protocol specs.
5890 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5891 in the network about change in the current ban list. The notify
5892 type is not used by the client.
5894 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5895 support the invite lists.
5897 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5899 * Added new function silc_string_regexify that converts string
5900 including wildcard characters into regex string that can
5901 be used by the GNU regex library. Added into the file
5902 lib/silcutil/silcutil.[ch].
5904 Added silc_string_regex_combine to combine to regex strings
5905 into one so that they can be used as one regex string by
5906 the GNU regex library. Added into the file
5907 lib/silcutil/silcutil.[ch].
5909 Added silc_string_regex_match to match two strings. It returns
5910 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5912 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5914 * Imported GNU regex to the soruce tree into lib/contrib.
5915 Fixed some compiler warning from the regex.c.
5917 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5919 * Fixed MOTD command in the server to work in router environment.
5921 * Fixed the MOTD command in the client library to support
5922 the server argument in the command.
5924 * Added `nickname_len' argument to the silc_idlist_add_client
5925 in the server, as the `nickname' argument may be binary data
5928 * Added silc_idlist_get_channels to return all channels from
5931 * Implemented LIST command to the server. Affected file is
5934 * Implemented the LIST command to the client library and on the
5937 * Added [<user count>] argument to the LIST command reply.
5938 With private channels the user count is not shown.
5940 * Updated TODO and README.
5942 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5944 * The client entry's data.registered must be TRUE even with
5945 global client entry on global client list. The data.registered
5946 is used to check whether the client is anymore in the network,
5947 for example with WHOWAS command so it must be valid.
5949 * Fixed the WHOWAS command in the server. It now actually works
5950 in router environment. Added function into silcd/command_reply.c
5951 silc_server_command_reply_whowas_save.
5953 * Added silc_idlist_purge function to the silcd/idlist.c
5954 to periodically purge the ID Cache.
5956 * Fixed INFO command in the server. It works now in router
5957 environment. Added <server name> argument to the INFO command
5958 reply. Updated the protocol specs.
5960 * Fixed minor bug in silc_idcache_purge to not purge if the
5961 expire value is zero.
5963 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5964 they were buggy because of the WHOWAS information.
5966 * Fixed local command MSG to handle the async resolving of
5967 the remote client properly. It used to fail the first MSG.
5968 Affected file silc/local_command.c.
5970 * Added `data_len' field to SilcIDCache context.
5972 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5974 * Update TODO. Todo in commands in the server.
5976 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5978 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5979 used by routers as broadcast packet to inform other routers
5980 about the changed user mode.
5982 Implemented the notify handling in the server. Affected file is
5983 silcd/packet_receive.c. Added the function
5984 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5986 * Added new generic Channel Payload and deprecated the New Channel
5987 Payload. The New Channel Payload is now the generic Channel
5990 * Added new argument `mode' to the silc_server_send_new_channel
5991 as it is required in the Channel Payload now.
5993 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5994 and created a new and real SilChannelPayload to represent the
5995 new generic Channel Payload. Implemented the encode/decode
5996 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5998 * Added silc_server_get_client_channel_list to return the list
5999 of channels the client has joined for WHOIS command reply.
6000 Affected file silcd/server.[ch].
6002 * Implemented the channel list sending in the WHOIS command reply
6003 in server and in the client.
6005 Implemented the channel list displaying on the user interface
6006 as well. Affected file silc/client_ops.c.
6008 * Added silc_channel_payload_parse_list to parse list of Channel
6009 Payloads. It returns SilcDList list of SilcChannelPayloads.
6010 Client for example can use this function to parse the list of
6011 channels it receives in the WHOIS command reply. The caller
6012 must free the list by calling silc_channel_payload_list_free.
6013 Affected files lib/silccore/silcchannel.[ch].
6015 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6017 * Added one new argument <user mode> to the WHOIS command reply
6018 to return the mode of the user in SILC. Updated the protocol
6021 Implemented it to the server and client.
6023 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6025 * Fixed the mode printing on the user interface on joining.
6026 Affected file silc/client_ops.c.
6028 * Implemented the UMODE command and user modes in general to the
6029 client library and to the user interface.
6031 * Implemented the UMODE command to the server.
6033 * The server now sends UNKNOWN_COMMAND error status if client sends
6034 unknown command. Affected file silcd/command.c.
6036 * All server commands now handle the command identifier the right
6037 way when sending the command reply to the client. The client can
6038 use to identify the command replies with the identifier.
6040 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6042 * Added silc_server_get_client_route to resolve the route to
6043 the client indicated by the client ID. Affected file is
6046 * Added silc_server_relay_packet as general function to relay
6047 packet to arbitrary destination. This deprecates functions
6048 like _send_private_message_key, _relay_notify etc. Affected
6049 file is silcd/packet_send.[ch].
6051 Removed silc_server_send_key_agreement,
6052 silc_server_send_private_message_key and
6053 silc_server_packet_relay_notify functions from the file
6054 silcd/packet_send.[ch].
6058 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
6059 server. Affected file silcd/packet_receive.[ch].
6061 * Implemented the KILL command to the client. Implemented the
6062 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
6063 Affected files lib/silcclient/command[_reply].c and
6064 lib/silcclient/client_notify.c. Implemented the KILL notify
6065 printing in the user inteface.
6067 * Fixed a lot silc_parse_nick memory leaks from the client
6068 library in the file lib/silcclient/command.c.
6070 * Changed the silc_server_send_notify_on_channels's `sender'
6071 argument from SilcSocketConnection to SilcClientEntry to
6072 check the sender as entry and not as connection object and not
6073 to send to the client provided as argument. The affected file
6074 is silcd/packet_send.[ch].
6076 * The notify packets that are destined directly to the client used
6077 to not to be processed by the server. Now changed that and the
6078 server processes all notify packets. After relaying the packet
6079 to the client the notify packet is processed in the server.
6081 * The silc_server_free_client_data now checks whether there is
6082 pending outgoing traffic for the client and purges the data to
6083 the network before removing the client entry.
6085 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6087 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
6088 an client is killed from the SILC Network. Updated the protocol
6091 Added new function silc_server_send_notify_killed to the
6092 silcd/packet_send.[ch].
6094 * Added function silc_server_packet_relay_notify to relay notify
6095 packets that are destined directly to a client. In this case
6096 the server does not process the notify packets but merely relays
6097 it to the client. Affected file silcd/packet_send.[ch].
6099 Added also silc_server_packet_process_relay_notify to check
6100 whereto relay the notify. Affected file is
6101 silcd/packet_receive.[ch].
6103 * Implemented the KILL command to the server.
6107 * Added the backup schema desgined last fall to the protocol
6108 specs for everyone to see. The specification is in the
6109 *-spec-xx.txt draft and the packet type definitions for the
6110 backup routers is in *-pp-xx.txt draft. Thusly, added also
6111 new packet type SILC_PACKET_CELL_ROUTERS.
6113 * A big security problem in the implementation discovered. The
6114 signoff of an client did not cause new channel key generation
6115 which it of course should've done. The channel keys must be
6116 always re-generated when client leaves (or signoffs) the channel.
6117 The silc_server_remove_from_channels funtion now handles
6118 the channel key re-generation.
6120 * Added `sender' argument to the silc_server_send_notify_on_channels
6121 to not to send the client provided as argument. Affected file
6122 silcd/packet_send.[ch].
6124 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6126 * Implemented OPER and SILCOPER commands into the server and
6129 * Added silc_auth_verify and silc_auth_verify_data to verify
6130 the authentication directly from the authentication payload.
6131 It supports verifying both passphrase and public key based
6132 authentication. Affected file lib/silccore/silcauth.[ch].
6134 * Added `hash' field to the SilcIDListData structure. It is the
6135 hash negotiated in the SKE protocol. Affected file is
6138 * Slight redesigning of the SilcAuthPayload handling routines.
6139 Do not send SilcPKCS but SilcPublicKey as argument.
6141 * Implemented the public key authentication support to the
6142 serverconfig. The public key is loaded from the provided path
6143 and saved as authentication data to void * pointer. Thus,
6144 changed the unsigned char *auth_data to void *auth_data;
6146 * Fixed SHUTDOWN command to send the reply before the server
6147 is shutdown. :) Affected file silcd/command.c.
6149 * Fixed fatal bug in CONNECT command. The hostname was invalid
6150 memory and server crashed. Affected file silcd/command.c.
6152 * Fixed fatal bug in CLOSE command. The server_entry became
6153 invalid but was referenced later in the command. Affected file
6156 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6158 * Fixed fatal bug in failure packet handling. Server ignored
6159 the failure and thus crashed when it came.
6163 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6165 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
6166 that the command may be executed only once in (about) 2 seconds.
6167 The old SILC_CF_LAG flag is same but allows command bursts up
6168 to five before limiting.
6170 Added the support for CF_LAG and CF_LAG_STRICT flags to the
6171 server code. Various commands now includes the CF_LAG_STRICT
6172 flag to disallow any kind of miss-use of the command.
6174 * Fixed the silc_buffer_unformat to not to allocate any data
6175 if the length of the data is zero. It used to allocate the
6176 length + 1. Affected file lib/silcutil/silcbuffmt.c.
6178 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6180 * Changed the format of AdminConnection configuration section
6181 in the server. Added username of the admin to the format.
6182 Affected files silcd/serverconfig.[ch].
6184 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
6185 to return admin configuration data by host, username and/or
6188 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6190 * Implemented WHOWAS command to the server. Added the functions:
6192 silc_server_command_whowas_parse,
6193 silc_server_command_whowas_send_reply,
6194 silc_server_command_whowas_from_client and
6195 silc_server_command_whowas_from_server
6197 * Added <Client ID> argument to the WHOWAS command reply. Updated
6198 the protocol specs accordingly.
6200 * Implemented WHOWAS command and command_reply to the client
6203 Implemented the WHOWAS printing on the user interface.
6205 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6207 * Added new argument to the WHOWAS command reply, the real name.
6208 It is an optional argument. Updated the protocol specs.
6210 * Added SilcIDCacheDestructor callback that is registered when
6211 the SilcIDCache is allocated. The callback is called when
6212 an cache entry in the ID Cache expires, or is purged from the
6213 cache. Added into lib/silccore/idcache.[ch].
6215 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
6216 to destruct the client entries when the cache entry expires.
6217 Other ID Cache's in server and in the client library ignores
6220 * If the ID Cache entry's `expire' field is zero then the entry
6221 never expires. Added boolean `expire' argument to the
6222 silc_idcache_add function in the lib/silccore/idcache.[ch].
6223 If it is TRUE the default expiry value is used.
6225 * Added silc_server_free_client_data_timeout that is registered
6226 when client disconnects. By default for 5 minutes we preserve
6227 the client entry for history - for WHOWAS command.
6229 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6231 * Added support to the server to enforce that commands are not
6232 executed more than once in 2 seconds. If server receives
6233 commands from client more frequently, timeout is registered
6234 to process the commands. Affected file silcd/command.c.
6235 Added new function silc_server_command_process_timeout.
6237 * Changed NICK_NOTIFY handling in client library to check that
6238 if the client's nickname was changed, so there is no need to
6239 resolve anything from the server.
6241 * Removed error printing from the WHOIS and IDENTIFY commands.
6242 If error occurs then it is ignored silently in the client library.
6243 The application, however, may map the received error to
6244 human readable error string. The application currently maps
6245 the NO_SUCH_NICKNAME error to string.
6247 * Made the command status message public to the application. Moved
6248 them from lib/silcclient/command_reply.c to
6249 lib/silcclient/command_reply.h. The application can map the
6250 received command status to the string with the
6251 silc_client_command_status_message function.
6253 * Added check to the server to check that client's ID is same
6254 as the Source ID in the packet the client sent. They must
6257 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6259 * Added dist-bzip hook to the Makefile.am to make bzip2
6260 compressed distributions.
6262 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6264 * Server now enforces the maximum length for the nickname and
6265 the channel as protocol specification dictates. 128 bytes for
6266 nickname and 256 bytes for channel name.
6268 * Moved the WHOIS printing to the application. The client libary
6269 does not print out the WHOIS information anymore, the application
6270 must do it. Renamed silc_client_command_reply_whois_print to
6271 the silc_client_command_reply_whois_save.
6273 The client's idle time is also sent to the application now, and
6274 the idle is shown on screen.
6276 * Added silc_client_command_reply_identify_save to save the
6277 received IDENTIFY entries.
6279 * Do not check for channel private keys in message sending and
6280 reception if the channel does not have the PRIVKEY mode set.
6281 Affected file lib/silclient/client_channel.c.
6283 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6285 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
6286 just surfaced after chaning the JOIN procedure.
6288 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6290 * Added silc_client_get_clients_by_list to get client entries
6291 from Client ID list, that is returned for example by JOIN
6292 and USERS command replies. The application should use this
6293 function for example when JOIN command reply is received to
6294 resolve the clients already on the channel (library does not
6295 do that anymore as USERS command reply is not used in the JOIN
6296 procedure anymore). Affected files lib/silcclient/silcapi.h and
6297 lib/silcclient/idlist.c.
6299 * JOIN command reply and USERS command reply returns now SilcBuffer
6300 pointers instead of unsigned char pointers when returning
6301 the client list and mode list.
6303 * Added <Client ID> argument to the JOIN command reply, mainly
6304 for the server to identify for which client the command was
6305 originally sent. Updated protocol specs accordingly.
6307 * Added SilcDlist private_key pointer to the SilcChannelEntry
6308 in the client to support the channel private keys. Affected
6309 file is lib/silcclient/idlist.h.
6311 * Added SilcChannelPrivateKey argument to the function
6312 silc_client_send_channel_message so that application can choose
6313 to use specific private ke if it wants to. If it is not provided,
6314 the normal channel key is used, unless private keys are set.
6315 In this case the first (key that was added first) is used
6316 as the encryption key.
6318 * Implemented the support for channel private key handling.
6319 Implemented the following functions:
6321 silc_client_add_channel_private_key,
6322 silc_client_del_channel_private_keys,
6323 silc_client_del_channel_private_key,
6324 silc_client_list_channel_private_keys and
6325 silc_client_free_channel_private_keys
6327 Affected file lib/silcclient/client_channel.c.
6329 * Added the support for the private keys in the channel message
6330 sending and encryption and in the message reception and
6331 decryption. Affected funtions are
6332 silc_client_send_channel_message and silc_client_channel_message.
6334 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6336 * Added SKE's key verify callback to the client library's
6337 KE protocol context. Affected files lib/silcclient/protocol.[ch].
6339 * Removed the statement that server (or router) must send USERS
6340 command reply when joining to the channel so that the client
6341 knows who are on the channel. Instead, the client list and
6342 client's mode list is now sent in the JOIN command reply to the
6343 client who joined channel. This is better solution.
6345 * Added function silc_server_get_users_on_channel and function
6346 silc_server_save_users_on_channel to the silcd/server.[ch].
6348 * Removed function silc_server_command_send_users from the
6351 * Do not show topic on the client library anymore. The topic is
6352 sent in the command reply notify to the application and the
6353 application must show the topic now.
6355 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6357 * Added client searching by nickname hash into the IDENTIFY and
6358 WHOIS commands in the server as they were clearly missing from
6359 them. Affected file is silcd/command.c.
6361 * Fixed a bug in private message receiving in the client library.
6362 The remote ID was freed and it wasn't supposed, now it is
6365 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6367 * Minor fix to the channel payload; allocate the data area, as it
6368 needs to be of specific length.
6370 * If the key agreement port is zero then the operating
6371 system will define the bound port. Affected files are
6372 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
6374 * Added new function silc_channel_payload_decrypt into the file
6375 lib/silccore/silcchannel.[ch].
6377 * Moved the channel message etc, check from silc_packet_decrypt
6378 to applications. The library calls now a generic
6379 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
6380 when the packet is either normal or special. This was done to
6381 allow more wide range of checking that was not allowed when
6382 the code was in library. Now applications can do virtually any
6383 checks to the packet and return to the library the decision how
6384 the packet should be processed. Affected files are
6385 lib/silccore/silcpacket.[ch].
6387 Added silc_server_packet_decrypt_check to the server and
6388 silc_client_packet_decrypt_check to the client library.
6390 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
6391 to send with specified source and destination information.
6393 * Channel message delivery between routers was broken after the
6394 channel key distribution was fixed earlier. The channel key
6395 was used be to distributed to other routers as well which is not
6396 allowed by the protocol. Now this is fixed and channel keys
6397 really are cell specific and the channel message delivery between
6398 routers comply with the protocol specification.
6400 * Fixed various commands in server to check also the global list
6401 for the channel entry and not just the local list. The affected
6402 file silcd/command.c.
6404 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6406 * Added assert()s to buffer formatting and unformatting routines
6407 to assert (if --enable-debug) when error occurs. Affected
6408 file: lib/silcutil/silcbuffmt.c.
6410 * Changed to auto-reconnect to check whether the remote host is
6411 router and register the re-connect timeout if it is. It used
6412 to check that whether we are normal server, but router must do
6413 auto-reconnect with another router as well. Affected file
6416 * Removed the [<key len>] option from CMODE command as the cipher
6417 name decides the key length, nowadays. See the defined ciphers
6418 from the protocol specification.
6420 * Added [<hmac>] option to the CMODE command to define the HMAC
6421 for the channel. Added SILC_CMODE_HMAC channel mode.
6423 * Added [<hmac>] option for the JOIN command so that user can
6424 select which HMAC is used to compute the MACs of the channel
6427 * Added Hmac field to the Channel Message Payload. The integrity
6428 of plaintext channel messages are now protected by computing
6429 MAC of the message and attaching the MAC to the payload. The
6430 MAC is encrypted. Now, it is clear that this causes some
6431 overhead to the size of the packet but rationale for this is that
6432 now the receiver can verify whether the channel message decrypted
6433 correctly and also when private keys are set for the channel the
6434 receiver can decrypt the packet with several keys and check from
6435 the MAC which key decrypted the message correctly.
6437 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
6438 lib/silccrypt/silccipher.[ch].
6440 * Added silc_hash_len to return the digest length into the
6441 lib/silcrypt/silchash.[ch].
6443 * Rewrote parts of Silc Channel Payload interface in the
6444 lib/silccore/silcchannel.[ch]. The encode function now also
6445 encrypts the packet and parse function decrypts it.
6447 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6449 * Fixed a minor formatting bug in the SKE's key material processing.
6450 It actually might have processed the keys wrong way resulting
6453 * Redefined the mandatory HMAC algorithms and added new algorithms.
6454 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
6455 and hmac-md5 truncated to 96 bits. The mandatory is now
6456 hmac-sha1-96. Rest are optional (including the one that used
6457 to be mandatory). Rationale for this is that the truncated HMAC
6458 length is sufficient from security point of view and can actually
6459 make the attack against the HMAC harder. Also, the truncated
6460 HMAC causes less overhead to the packets. See the RFC2104 for
6463 * Added new [hmac] configuration section. The SKE used to use
6464 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
6465 is of course wrong. The official names that must be proposed in
6466 the SKE are the ones defined in the protocol specification
6467 (hmac-sha1-96 for example). The user can configure any hmac
6468 using any hash function configured in the [hash] section. At
6469 least, the mandatory must be configured.
6471 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
6473 * Added HMAC list to the SKE proposal list. It has now both
6474 hash algorithm list and HMAC list. This makes the protocol
6475 incompatible with previous versions. The SKE now seems to work
6476 the way it is supposed to work, for the first time actually.
6478 * Defined plain Hash algorithms to the protocol specification.
6481 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6483 * Implemented support for key agreement packets into the server.
6484 Added functions silc_server_key_agreement and
6485 silc_server_send_key_agreement. Other than these functions,
6486 server has nothing to do with this packet.
6488 * Added support for private message key packets into the server.
6489 Added functions silc_server_private_message_key and
6490 silc_server_send_private_message_key.
6494 * Changed the silc_[client|server]_protocol_ke_set_keys to be
6495 called in the protocol's final callback instead in the END
6496 protocol state. This makes a little more sense and in the same
6497 time in client we can use the same protocol routines for normal
6498 key exchange and to key agreement packet handling as well.
6500 * Added to both client's and server's KE protocol context the
6501 SilcSKEKeyMaterial pointer to save the key material. We will
6502 bring the key material to the protocol's final callback by doing
6503 this. The final callback must free the key material.
6505 * Added SKE's packet_send callback into client's KE protocol
6506 context so that the caller can choose what packet sending function
6507 is used. This way we can use different packet sending when
6508 doing normal SKE when doing key agreement packet handling (in
6509 the key agreement packet handling we do not want to encrypt
6512 * Implemented the responder side of the key agreement routines
6513 in the client. The client can now bind to specified port and
6514 accept incoming key negotiation. The key material is passed
6515 to the application after the protocol is over.
6517 * Implemented the processing of incoming Key Agreement packet
6518 in the client. Added function silc_client_key_agreement to
6521 * Implemented the intiator side of the key agreement routines
6522 in the client. The client can now initiate key agreement with
6523 another remote client. The key material is passed to the
6524 application after the protocol is over.
6526 * Created client_keyagr.c to include all the key agreement
6529 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
6530 SILC_TASK_CALLBACK except that it is not static.
6532 * Created client_notify.c and moved the Notify packet handling
6533 from the client.[ch] into that file.
6535 * Created client_prvmsg.c and moved all private message and
6536 private message key routines from the client.[ch] into that file.
6538 * Create client_channel.c and moved all channel message and
6539 channel private key routines from the client.[ch] into that file.
6541 * Changed silc_client_get_client_by_id_resolve to resolve with
6542 WHOIS command instead of IDENTIFY command, in the file
6543 lib/silclient/idlist.c.
6545 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6547 * Implemented the SKE's responder side to the Client library.
6549 * When FAILURE is received to the protocol do not trust it
6550 blindly. Register a timeout to wait whether the remote closes
6551 the connection as it should do it, only after that process the
6552 actual failure. This was changed to both client and server.
6554 * Added client_internal.h to include some of the structures
6555 there instead of client.h in lib/silcclient/.
6557 * Added function silc_task_unregister_by_callback to unregister
6558 timeouts by the callback function.
6560 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6562 * Some "Incomplete WHOIS info" errors has been appearing on the
6563 log files. Took away the entry->userinfo check from WHOIS
6564 reply sending. The entry->userinfo is now " " if client did not
6565 provide one. I thought this was fixed earlier but something
6566 is wrong still. Let's see if the error still appears.
6568 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6570 * Fixed a minor bug in the login when the channel key is
6571 re-generated in the server. It used to generate the key in
6572 wrong order and thus caused problems in the channel traffic.
6574 * Fixed a minor bug in channel key distsribution after
6575 KICK command. The key was not sent to the router even though
6578 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6580 * Added silc_ske_process_key_material_data as generic routine
6581 to process any key material as the SILC protocol dictates. The
6582 function is used by the actual SKE library but can be used by
6583 applications as well. This relates to the private message keys
6584 and the channel private keys since they must be processed the
6585 same way the normal SILC session keys. The protocol dictates
6586 this. Affected files: lib/silcske/silcske.[ch].
6588 Added also silc_ske_free_key_material to free the
6589 SilcSKEKeyMaterial structure.
6591 * Defined silc_cipher_set_key function to set the key for
6592 cipher without using the object's method function. The affected
6593 files: lib/silccrypt/silccipher.[ch].
6595 * Implemented silc silc_client_add_private_message_key,
6596 silc_client_add_private_message_key_ske,
6597 silc_client_del_private_message_key,
6598 silc_client_list_private_message_keys and
6599 silc_client_free_private_message_keys functions in the
6602 Added functions silc_client_send_private_message_key to send
6603 the Private Message Key payload and silc_client_private_message_key
6604 to handle incoming Private Message Key payload.
6606 * Added Cipher field to the Private Message Key payload to set
6607 the cipher to be used. If ignored, the default cipher defined
6608 in the SILC protocol (aes-256-cbc) is used.
6610 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6612 * Removed lib/silcclient/ops.h file.
6614 Redefined parts of the SILC Client Library API. Created new
6615 file silcapi.h that deprecates the ops.h file and defines the
6616 published Client Library API. Defined also private message key
6617 API and channel private key API into the file.
6619 This is the file that the application must include from the
6620 SILC Client Library. Other files need not be included by
6621 the application anymore.
6623 * Added new key_agreement client operation callback and also
6624 defined the Key Agreement library API for the application.
6626 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6628 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
6629 is used by clients to request key negotiation between another
6630 client in the SILC network. If the negotiation is started it
6631 is performed using the SKE protocol. The result of the
6632 negotiation, the secret key material, can be used for example
6633 as private message key.
6635 Implemented the Key Agreement payload into the files
6636 lib/silccore/silauth.[ch].
6638 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6640 * Redefined ciphers for the SILC protocol. Added some new ciphers
6641 and defined the key lengths for the algorithms. Changed the
6642 code accordingly. The default key length is now 256 bits.
6644 * Fixed SKE key distribution function silc_ske_process_key_material
6645 when the key length is more than 128 bits. The default key
6646 length in SILC is now 256 bits.
6648 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
6649 to indicate unsupported algorithm.
6651 * Renamed rijndael.c to aes.c and all functions as well.
6653 * Fixed a long standing channel key setting bug in client library.
6654 Weird that it has never surfaced before.
6656 * Fixed bug in channel deletion. If the entire channel is removed
6657 then it must also delete the references of the channel entry
6658 from the client's channel list as the client's channel entry and
6659 the channel's client entry share same memory.
6661 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6663 * Implemented CONNECT and SHUTDOWN commands in the client.
6665 * Implemented CLOSE command to the client.
6667 * Added the function silc_idlist_find_server_by_name into the
6668 files silcd/idlist.[ch].
6670 Added the function silc_idlist_find_server_by_conn into the
6671 files silcd/idlist.[ch].
6673 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6675 * DIE command was renamed to SHUTDOWN. Updated the both code
6678 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
6679 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
6681 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
6684 * Added function silc_server_create_connection function to create
6685 connection to remote router. My server implementation actually
6686 does not allow router to connect to normal server (it expects
6687 that normal server always initiates the connection to the router)
6688 so the CONNECT command is only good for connecting to another
6691 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6693 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
6694 or some other client was kicked from the channel.
6696 Implemented the handling of the notify type to both client
6699 Implemented silc_server_send_notify_kicked to send the KICKED
6700 notify. It is used to send it to the server's primary router.
6702 * Implemented the KICK command into server and client.
6704 * Added `query' argument to the silc_idlist_get_client function
6705 to indicate whether to query the client from server or not if
6708 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
6709 to indicate that the client is not channel founder.
6713 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6715 * Removed the rng context from SilcPacketContext structure and
6716 changed that the packet routine uses the Global RNG API.
6718 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6720 * Added support for quit message that client can "leave" on the
6721 channel when it quits the SILC. It is ditributed inside the
6722 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6724 Added silc_server_free_client_data that will take the
6725 signoff message as argument.
6727 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6729 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6731 * Updated parts of the protocol specification to keep it up
6734 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6736 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6737 payloads in one packet.
6739 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6740 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6741 use now the new List flag.
6743 * Also deprecated the following packet types: REPLACE_ID,
6744 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6746 * Added list support for Notify packet in server.
6748 * Added silc_server_send_notify_channel_change to send the
6749 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6750 the silc_server_send_replace_id.
6752 * Added silc_server_send_notify_nick_change to send the
6753 NICK_CHANGE notify type. Deprecates the function
6754 silc_server_send_replace_id.
6756 * Added silc_server_send_notify_join to send the JOIN notify type.
6757 Deprecates the function silc_server_send_new_channel_user.
6759 * Added silc_server_send_notify_leave to send LEAVE notify type.
6760 Deprecates the function silc_server_send_remove_channel_user.
6762 * Added silc_server_send_notify_cmode and
6763 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6764 types. Deprecates the silc_server_send_set_mode function.
6766 * Added SERVER_SIGNOFF notify type to indicate that server has
6767 quit. This means that all clients on the channel from that
6768 server will drop. This can be also used when netsplit happens.
6770 Deprecated REMOVE_ID packet type since it is not needed anymore
6773 Added silc_server_send_notify_server_signoff to send the
6774 SERVER_SIGNOFF notify type. Deprecates the function
6775 silc_server_send_remove_id.
6777 Added also silc_server_send_notify_signoff to send the
6778 SIGNOFF notify type.
6780 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6781 SILC protocol from this day on. Changed the protocol
6782 specification as well.
6784 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6785 notify type. It is used between routers to notify about
6786 topic changes on a channel.
6788 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6791 * Partly updated the protocol specification to comply with the
6792 changes now made. It is still though a bit outdated.
6794 * The JOIN notify type now takes one extra argument <Channel ID>.
6795 The packet used to be destined to the channel but now the
6796 JOIN type may be sent as list thus it is impossible to
6797 destine it to any specific channel. By adding this argument
6798 it is again possible.
6800 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6802 * Added CREDITS file. The CHANGES and CREDITS file will appear
6803 in the distribution as well.
6805 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6807 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6808 types in the server's silcd/packet_receive.c.
6810 * Implemented CMODE and CUMODE to work in router environment.
6812 * Fixed minor encoding and decoding buglet from the
6813 lib/silccore/silcmode.c.
6815 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6818 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6820 * Changed all SilcConfigServer* and silc_config_server* to
6821 SilcServerConfig* and silc_server_config*, respectively.
6824 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6826 * Associated the ID (client or server ID) to the Authentication
6827 Payload to avoid any possibility of forging. Updated the
6828 protocol specification and the code accordingly.
6830 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6832 * The RSA key length is now save to the RsaKey context in the
6833 key generation process in lib/silccrypt/rsa.c. The key length
6834 is now used to figure out the maximum size of the block allowed
6835 to be encrypted/signed.
6837 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6838 is equivalent to the silc_mp_mp2bin but does not allocate any
6841 * Changed silc_mp_mp2bin API to take length argument. If it is
6842 non-zero then the buffer is allocated that large. If zero, then
6843 the size is approximated using silc_mp_sizeinbase, which however
6846 * Created Global RNG API which is global RNG that application can
6847 initialize. After initializing, any routine anywhere in the
6848 code (including library) can use RNG without allocating a new
6849 RNG object. This was done to allow this sort of use of the
6850 RNG in code that has no chance to allocate RNG object. All
6851 applications currently allocate this and many routines in the
6852 library use this. Affected file lib/silccrypt/silcrng.[ch].
6854 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6855 it to use the Global RNG API.
6857 * Defined Authentication Payload into protocol specification that
6858 is used during SILC session to authenticate entities. It is
6859 used for example by client to authenticate itself to the server
6860 to obtain server operator privileges.
6862 Implemented this payload into the lib/silccore/silcauth.[ch].
6863 Implemented also routines for public key based authentication
6864 as the new protocol specification dictates.
6866 Moved definitions of different authentication methods from
6867 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6869 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6870 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6871 silc_pkcs_verify_with_hash functions into the file
6872 lib/silccrypt/silcpkcs.[ch].
6874 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6876 * The client entry's userinfo pointer must be always valid.
6877 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6878 will fail since it requires the userinfo. Now, the userinfo
6879 is allocated as "" if actual userinfo does not exist. Actually,
6880 it must exist and it is totally Ok to drop client connections
6881 that does not announce the userinfo. However, we will make
6882 this workaround for now.
6884 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6885 to return the remote port by socket.
6887 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6889 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6890 SILC_SERVER_PENDING_EXEC and added an new macro
6891 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6892 data or when error occurs while processing the pending command.
6894 Added new argument `destructor' into silc_server_command_pending
6895 and to the SilcServerCommandPending object. This destructor is
6896 now called after calling the pending callback or if error occurs
6897 immediately. If error occurs the actual pending callback won't
6898 be called at all - only the destructor. The destructor may be
6899 NULL if destructor is not needed.
6901 All this applies for client library code as well. Similar
6902 changes were made there as well for the pending commands.
6904 In the client, the application must now allocate the
6905 SilcClientCommandContext with the silc_client_command_alloc
6908 * Added reference counter to the SilcServerCommandContext. Added
6909 function silc_server_command_alloc and silc_server_command_dup
6912 Same type of functions added to the client library for the same
6915 * Removed the cmd_ident from IDListData away since it is now
6916 global for all connections. It is the command identifier used
6917 in command sending and with pending commands. The affected file
6920 * Added reference counter to the SilcSocketConnection objecet to
6921 indicate the usage count of the object. The object won't be
6922 freed untill the reference counter hits zero. Currently only
6923 server uses this, and client ignores it. The client must be
6924 set to use this too later. The affected files are
6925 lib/silccore/silcsockconn.[ch]. Added also the function
6926 silc_socket_dup to increase the reference counter.
6928 This was mainly added because it is possible that the socket
6929 is removed underneath of pending command or other async
6930 operation. Now it won't be free'd and proper DISCONNECTING
6931 flags, etc. can be set to avoid sending data to connection that
6932 is not valid anymore.
6934 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6935 the connection. After that it sets SILC_SET_DISCONNECTED.
6936 It is, however, possible that the socket data is not still freed.
6937 The silc_server_packet_process now checks that data is not
6938 read or written to connection that is DISCONNECTED. The socket
6939 get's freed when the reference counter hits zero.
6941 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6943 * Changed the client operation API: channel_message operation's
6944 `sender' is now the client entry of the sender, not the nickname
6945 and the `channel' is the channel entry, not the channel name.
6947 In the private_message operation the `sender' is now also the
6948 client entry of the sender not the nickname.
6950 Affected file is lib/silcclient/ops.h and all applications
6951 using the client operations.
6953 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6955 * Moved the calling of ops->connect() from connect_to_server_final
6956 into receive_new_id functin since that is the point when the
6957 client is actually allowed to send traffic to network. The
6958 affected file is lib/silcclient/client.c.
6960 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6962 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6963 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6964 (if needs broadcasting) instead of broadcasting the packets one
6965 by one which would make a burst in the network traffic.
6967 * Added `broadcast' argument to the functions in silcd/server.[ch]
6968 silc_server_create_new_channel[_with_id] to indicate whether
6969 to send New Channel packet to primary router.
6971 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6973 * Added new function into the silcd/server.[ch] files:
6974 silc_server_create_new_channel_with_id to create new channel with
6975 already existing Channel ID.
6977 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6978 lib/silccore/silcpacket.h. This packet is used t send list of
6979 Set Mode payloads inside one packet. Server uses this to set
6980 the modes for the channels and clients on those channels, that it
6981 announced to the router when it connected to it. The protocol
6982 specification has been updated accordingly.
6984 * The silc_server_new_channel did not handle the packet coming
6985 from normal server as it normally does not send that. However,
6986 when it announces its channels it does send it. Implemented
6987 the support for that.
6989 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6990 into the file lib/silccore/id.h.
6992 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6994 * Fixed memory leaks in the functions silc_idlist_del_client,
6995 silc_idlist_del_channel and silc_idlist_del_server in the file
6996 silcd/idlist.c. All of those leaked like a sieve.
6998 * Fixed some small memory leaks in the client's function
6999 silc_client_notify_by_server.
7001 * Added functions into silcd/server.c: silc_server_announce_clients,
7002 silc_server_announce_channels and silc_server_announce_server.
7003 These functions are used by normal and router server to announce
7004 to its primary router about clients, channels and servers (when
7005 router) that we own. This is done after we've connected to the
7008 These functions effectively implements the following packet types:
7009 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
7010 and SILC_PACKET_NEW_ID_LIST.
7012 * Added new functions into the silcd/packet_receive.[ch]:
7013 silc_server_new_id_list, silc_server_new_channel_list and
7014 silc_server_new_channel_user_list to handle the incoming
7015 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
7017 * Added support of changing Channel ID in the function
7018 silc_server_replace_id. If the server that announces a channel
7019 to the router already exists in the router (with same name but
7020 with different Channel ID), router is responsible to send
7021 Replace ID packet to the server and force the server to change
7022 the Channel ID to the one router has.
7024 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
7025 client that the Channel ID has been changed by the router. The
7026 normal server sends this to the client. Client must start using
7027 the new Channel ID as the channel's ID.
7029 Implemented handling of this new type into lib/silcclient/client.c
7030 into the function silc_client_notify_by_server.
7032 * Added new function silc_idlist_replace_channel_id into the files
7033 silcd/idlist.[ch] to replace the Channel ID.
7035 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7037 * Call silc_server_command_identify_check always when processing
7038 the IDENTIFY command in silcd/command.c
7040 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7042 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
7043 send keepalive packets. The packet can be sent by clients,
7044 servers and routers.
7046 Added function silc_socket_set_heartbeat into the file
7047 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
7048 If not set, the heartbeat is not performed. The actual
7049 heartbeat is implemented in the low level socket connection
7050 library. However, application is responsible of actually
7053 Added silc_server_send_heartbeat to send the actual heartbeat
7054 packet into silcd/packet_send.[ch]. Server now performs
7055 keepalive with all connections.
7057 * Added silc_task_get_first function into lib/silcutil/silctask.c
7058 to return the timeout task with shortest timeout. There was a bug
7059 in task unregistration that caused problems. TODO has been
7060 updated to include that task system must be rewritten.
7062 * The client library will now resolve the client information when
7063 receiving JOIN notify from server for client that we know but
7064 have incomplete information.
7066 * Rewrote parts of silc_server_remove_from_channels and
7067 silc_server_remove_from_one_channel as they did not remove the
7068 channel in some circumstances even though they should've.
7070 * Encryption problem encountered in server:
7072 The LEAVE command used to send the Channel Key packet to the
7073 router immediately after generating it. However, the code
7074 had earlier sent Remove Channel user packet but not immediately,
7075 ie. it was put to queue. The order of packets in the router
7076 was that Channel Key packet was first and Remove Channel User
7077 packet was second, even though they were encrypted in the
7078 reverse order. For this reason, MAC check failed. Now, this
7079 is fixed by not sending the Channel Key packet immediately but
7080 putting it to queue. However, this is more fundamental problem:
7081 packets that are in queue should actually not be encrypted
7082 because packets that are sent immediately gets encrypted
7083 actually with wrong IV (and thus MAC check fails). So, packets
7084 that are in queue should be encrypted when they are sent to
7085 the wire and not when they put to the queue.
7087 However, the problem is that the current system has not been
7088 designed to work that way. Instead, the packet is encrypted
7089 as soon as possible and left to the queue. The queue is then
7090 just purged into wire. There won't be any fixes for this
7091 any time soon. So, the current semantic for packet sending
7094 o If you send packet to remote host and do not force the send
7095 (the packet will be in queue) then all subsequent packets to the
7096 same remote host must also be put to the queue. Only after the
7097 queue has been purged is it safe again to force the packet
7100 o If you send all packets immediately then it safe to send
7101 any of subsequent packets through the queue, however, after
7102 the first packet is put to queue then any subsequent packets
7103 must also be put to the queue.
7105 Follow these rules and everything works fine.
7107 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7109 * Added new function silc_server_remove_clients_by_server to
7110 remove all client entries from ID list when the server connection
7111 is lost. In this case it is also important to invalidate all
7112 client entires as they hold the invalid server entry. This
7113 fixes fatal bug when server has lost connection and will reconnect
7116 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7118 * Made some sanity checks to silc_server_daemonise like to check
7119 whether the requested user and group actually exists.
7121 * Added sanity check to SKE's silc_ske_responder_finish to check
7122 that the public and private key actually is valid.
7124 * Invalidate the client's nickname when receiving Replace ID
7125 packet and the Client ID is being replaced. This means that the
7126 server will query the nickname if someone needs it (client)
7129 * Sort the ID Cache in client library when the ID Cache data
7130 has changed (needs sorting).
7132 * Do not allow for SILC client to create several connections to
7133 several servers. The client does not support windows right now
7134 and generating multiple connections causes weird behaviour.
7136 Irssi-silc client does support windows and can handle several
7137 connections without problems, see: www.irssi.org and SILC plugin.
7139 * Fixed some places where client was added to the IDList. The
7140 rule of thumb is following (in order to get everything right):
7141 If the client is directly connected local client then the
7142 `connection' argument must be set and `router' argument must be
7143 NULL to silc_idlist_add_client function. If the client is not
7144 directly connected client then the `router' argument must
7145 bet set and the `connection' argument must be NULL to the
7146 silc_idlist_add_client function.
7148 * The funtion silc_server_packet_send_local_channel actually did
7149 not check whether the client was locally connected or not. It
7150 does that now. Fixed a bug related to LEAVE command.
7152 * Fixed Remove Channel User payload parsing bug in server's
7153 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
7155 * The server's silc_server_save_channel_key now checks also the
7156 global ID list for the channel as it might not be in the local
7157 list. Fixed a bug related to LEAVE command.
7159 * Is this the end of the [<unknown>] buglet that has been lurking
7160 around for a long time? A little for loop fix in server's
7161 silc_server_command_whois_parse that is used by both IDENTIFY
7162 and WHOIS command. At least, this was a clear bug and a cause
7163 of one type of [<unknown>] buglet.
7165 * WHOIS and IDENTIFY commands call the function
7166 silc_server_command_[whois/identify]_check function even if
7167 we are not router server.
7169 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7171 * Added --with-gmp configuration option. If set the GMP
7172 is always compiled in the SILC source tree. If not set then
7173 it is checked whether the system has the GMP3 installed. If
7174 it has then the GMP won't be compiled (the system's headers
7175 and library is used), if it doesn't have it then the GMP is
7176 compiled in the SILC source tree.
7178 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7180 * Changed RSA private exponent generation to what PKCS #1
7181 suggests. We try to find the smallest possible d by doing
7182 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
7183 not security fix but optimization.
7185 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7187 * Added new config entry [Identity] to fork the server and run
7188 it as specific user and group. A patch from Bostik.
7190 * Imported Dotconf configuration library into lib/dotconf.
7191 This will be used to create the SILC configuration files later.
7192 It will appear in the distsribution after this commit.
7194 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7196 * A big code auditing weekend happening. Auditing code for
7197 obvious mistakes, bugs and errors. Also, removing any code
7200 Removed files for being obsolete:
7202 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
7203 inline in the file lib/silcutil/silcbuffer.h)
7205 o lib/silcutil/silcbufutil.c (the header has inline versions)
7207 Changed code to fix possible error conditions:
7209 o The buffer formatting routines now check that the destination
7210 buffer really has enough space to add the data. This applies for
7211 both buffer formatting and unformatting
7212 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
7213 unformatting was changed to accomodate following rules:
7214 XXX_*STRING_ALLOC will allocate space for the data into the pointer
7215 sent to the function while XXX_*STRING will not allocate or copy
7216 the data into the buffer. Instead it sets the pointer from the
7217 buffer into the pointer sent as argument (XXX_*STRING used to
7218 require that the pointer must be allocated already). This change
7219 makes this whole thing a bit more consistent and more optimized
7220 (note that the data returned in the unformatting with XXX_*STRING
7221 must not be freed now). The routines return now -1 on error.
7223 o Tried to find all code that use buffer_format and buffer_unformat
7224 and added return value checking to prevent formatting and
7225 especially unformatting errors and possible subsequent fatal
7228 o Changed ske->x and ske->KEY to mallocated pointers in
7229 lib/silcske/silcske.h. Fixed possible data and memory leak.
7231 o Added return value checking to all *_parse* functions. Fixed
7232 many memory leaks as well.
7234 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
7235 so that buffer overflows would not happen. All code now also
7236 checks the return value as it can fail.
7238 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7240 * Added reconnection support to server if the normal server looses
7241 its connection to the router (for example if router is rebooted).
7242 The server performs normal reconnection strategy implemented
7243 to the server. Affected file silcd/server.c.
7245 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7247 * Added new packet type SILC_PACKET_SET_MODE that is used to
7248 distribute the information about changed modes (for clients,
7249 channels and clients channel modes) to all routers in the
7250 network. Updated the protocol specification accordingly.
7252 Added functions into silcd/packet_send.c and
7253 silcd/packet_receive.c: silc_server_send_set_mode,
7254 silc_server_set_mode.
7256 Added new files silcmode.[ch] into lib/silccore that implements
7257 the encoding and decoding of Set Mode Payload. Added new type
7258 SilcSetModePayload. Moved the definitions of different modes
7259 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
7261 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7263 * Oops, a little mistake in server's connection authentication
7264 protocol. The protocol is not ended with FAILURE but with
7265 SUCCESS if the authentication is Ok. :) Affected file is
7268 * Implemented NICK_CHANGE notify handling in server in the file
7269 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
7270 the local clients on the channel. After the changing nickname
7271 in router environment snhould work and the [<unknown>] nickname
7272 should appear no more.
7274 The silc_server_replace_id function that receives the Replace ID
7275 payload now sends the NICK_CHANGE notify type also in the file
7276 silcd/packet_receive.c
7278 * Changed WHOIS and IDENTIFY command to support the maximum amount
7279 of arguments defined in protocol specs (3328 arguments). This
7280 fixed a bug that caused problems when there were more than three
7283 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7285 * Added extra parameter, command identifier, to the
7286 silc_client_send_command so that explicit command identifier
7289 Changed that ID list routines uses specific command identifier
7290 when sending WHOIS/IDENTIFY requests to the server so that they
7291 can be identified when the reply comes back.
7293 Affected files lib/silcclient/command.[ch],
7294 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
7296 * Added `sender' argument to silc_server_packet_send_to_channel
7297 to indicaet the sender who originally sent the packet to us
7298 that we are now re-sending. Ignored if NULL. Affected file
7299 silcd/packet_send.[ch].
7301 * Added some server statistics support in silcd/server_internal.h
7302 SilcServerStatistics structure and around the server code. Also
7303 send some nice statistics information when client is connecting
7306 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7308 * Fixed channel ID decoding in server's JOIN command reply in
7309 silcd/command_reply.c
7311 * Fixed braodcasting of replace ID payload to not to send it if
7312 we are standalone server in silcd/packet_receive.c.
7314 * Fixed all channel message sending routines to not to send
7315 packets to clients that has router set, since they are routed
7316 separately in the same function earlier. Affects file
7317 silcd/packet_send.c and all channel packet sending functions.
7319 * In USERS reply, res_argv[i] are not allocated, the table
7320 is allocated. Thus changed that free the table, not its
7323 * In server's whois_check and identify_check if the client is
7324 locally connected do not send any WHOIS commands - they are not
7327 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7329 * Fixed some minor bugs in client when sending WHOIS command. The
7330 arguments was in wrong order.
7332 * Removed statis function add_to_channel from server in
7333 silcd/command.c that was previously used with the joining but
7336 * Tested USERS command in router environment successfully with two
7337 routers, two servers and two clients.
7339 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7341 * Reorganized the USERS command and command reply in client library
7342 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
7343 When the command is given by user we register a pending command
7344 callback that will reprocess the command after the reply has been
7345 received from the server. When reprocessing the packet we then
7346 display the information. Thus, the USERS information is displayed
7347 now in the command callback instead of in the command reply
7348 callback. The processing of the command is same as previously
7349 when server has sent the command reply in the JOINing process.
7351 * Added to USERS command in silcd/command_reply.c to join the client,
7352 we didn't use to know about, to the channel after we've created
7353 a client entry for it. Also, for clienet we did know already still
7354 check whether it is on the channel or not and add it if not.
7356 * Removed silc_server_command_join_notify as the function and its
7359 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7361 * Changed the client's pending command handling to the same as the
7362 server's pending command handling. It is also now possible to
7363 execute command reply functions from other command reply
7364 function as the function callbacks for commands and command
7365 replies are one and same. The pending commands are not static
7366 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
7367 in client connection context. Thus, pending commands are server
7368 connection specific as it is convenient.
7370 Changed the function silc_client_command_pending and
7371 silc_client_command_pending_del and added new function
7372 silc_client_command_pending_check. Removed the
7373 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
7376 * Added cmd_ident, current command identifier, to the client
7377 connection context in lib/silcclient/client.h to keep track on
7378 command identifiers used in command sending. Client's command reply
7379 function handling now supports the mandatory command identifiers.
7381 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
7382 funtions in client to fully support pending command callbacks.
7384 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
7385 as one of the arguments to the application in the command reply
7388 * NOTE: The FORWARDED flag is depracated. It used to be depracated
7389 before first releasing SILC but came back. Now it is removed again
7390 and should come back nomore. The FORWARDED flag was used only
7391 by the JOINing procedure by forwarding the command packet to router.
7392 Now, the JOINing procedure has been changed to more generic (due
7393 to various router environment issues) and FORWARDED is not needed
7394 anymore for anything. The protocol specification is yet to be
7397 Now, removed silc_server_packet_forward from server and the flag
7398 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
7400 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7402 * Renamed NAMES command to USERS command. The NAMES was named that
7403 due to historical reasons. Now it is renamed. Also, rewrote
7404 parts of the USERS command. The nickname list is not sent anymore
7405 by the server. Only Client ID and mode lists are sent in the USERS
7406 command. Changed this also to the protocol specification.
7408 The client now resolves the names and stuff after it receives
7409 the USERS list from the server when joining to the channel.
7411 * WHOIS and IDENTIFY commands has been changed to support multiple
7412 Client ID's per command. One can now search for multiple users
7413 in the network by sending only one WHOIS or IDENTIFY command.
7414 Changed the code and the protocol specifications.
7416 * Removed silc_server_command_identify_parse and changed that IDENTIFY
7417 uses silc_server_command_whois_parse to parse the request. */
7419 * If normal server, do not parse the WHOIS and IDENTIFY requests
7420 before sending it to the router. Saves some time.
7422 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7424 * Fixed JOIN command on client library. Wrong number of arguments
7425 used to crash the client.
7427 * Added silc_server_channel_has_global function to check whether
7428 channel has global users or not.
7430 * Added silc_server_channel_has_local function to check whether channel
7431 has locally connected clients on the channel.
7433 * The silc_server_remove_from_one_channel now checks whether the
7434 channel has global users or not after given client was removed from
7435 the channel. It also checks whether the channel has local clients
7436 on the channel anymore. If it does not have then the channel entry
7437 is removed as it is not needed anymore.
7439 * The silc_server_notify now checks on JOIN notify whether the joining
7440 client is one of locally connected or global. If it is global then
7441 the channel has now global users on the channel and that is marked
7442 to the channel entry. Also, it now saves the global client to
7443 global list who is joining and JOINs it to the channel. This is
7444 for normal server, that is.
7446 Changed silc_server_send_notify_on_channel,
7447 silc_server_packet_relay_to_channel and
7448 silc_server_packet_send_to_channel check if we are normal server
7449 and client has router set (ie. global client) do not send the
7450 message to that client, as it is already routed to our router.
7452 * Implemented LEAVE notify type handling in silc_server_notify
7455 * Tested LEAVE command in router environment successfully. Tested
7456 with two routers, two servers and two clients.
7460 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
7462 * Implemented SIGNOFF notify type handling in silc_server_notify
7465 * silc_server_remove_id now removes the client entry from all channels
7466 it has joined and thusly sends SIGNOFF notify type.
7468 * Rewrote the NAMES list generation in server by removing two excess
7469 loops. The lists are created now inside one loop.
7471 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7473 * silc_server_remove_channel_user checks now also global list
7474 for channel and client.
7476 * silc_server_new_channel_user checks now both local and global
7477 list for channel and client. Fixed a bug in client id decoding.
7478 Used to decode wrong buffer.
7480 * silc_server_channel_message checks now both local and global
7481 list for channel entry.
7483 * Tested channel joining (hence JOIN) in router environment
7484 successfully. Tested with two routers, two servers and two
7487 * Tested channel message sending in router environment successfully.
7489 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7491 * Added silc_server_save_channel_key into server.[ch] to save the
7492 received channel key in Channel Key payload processing. It is
7493 also used in JOIN command reply handling.
7495 Equivalent function silc_client_save_channel_key added into
7496 client.[ch] into client library.
7498 * Changed JOIN command reply to send information whether the channel
7499 was created or not (is existing already) and the channel key
7500 payload. Changed protocol specs accordingly.
7502 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
7503 the request was sent by ID and not by nickname. Crashed on
7506 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7508 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
7509 now correctly save the received data.
7511 * silc_server_free_sock_user_data now notifies routers in the
7512 network about entities leaving the network.
7514 At the same time implemented functions silc_server_remove_id
7515 and silc_server_send_remove_id to receive and send REMOVE_ID
7516 packets. The packet is used to notify routers in the network
7517 about leaving entities. The ID removed will become invalid in
7520 * Added function silc_idlist_del_server into server. Removes and
7521 free's server entry from ID list.
7523 * silc_server_private_message function now checks, if we are router,
7524 that the destination ID really is valid ID, naturally.
7526 * In router when NEW_ID packet is received (for new client) the
7527 hash of the Client ID is saved in the ID Cache but the
7528 client->nickname is set to NULL, instead of putting the hash
7531 IDENTIFY command now also checks that client->nickname must be
7532 valid. If it is not if will request the data from the server who
7533 owns the client. Added new function
7534 silc_server_command_identify_check.
7536 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
7537 to set the command to already allocated Command Payload.
7539 * Tested private message sending in router environment with two
7540 routers, two servers and two clients. Fixed minor bugs and now
7543 * Fixed segfault from client's NAMES command. Used to crash if
7546 * Forwarded packets must not be routed even if it is not destined
7547 to the receiver. Changed server code comply with this.
7549 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7551 * Added `require_reverse_mapping' boolean value to ServerParams
7552 structure. If TRUE (not default) the server will require that
7553 the connecting host has fully qualified domain name.
7555 If the reverse mapping is not required and hostname could not be
7556 found the IP address is used as hostname.
7558 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7560 * Implemented version string checking to both client and server.
7561 The check is incomplete currently due to the abnormal version
7562 strings used in development version of SILC.
7564 * Changed all command functions in server to use the new
7567 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7569 * Changed char *data to unsigned char *data in ID Cache system to
7570 support binary data as ID Cache data. Changed code to support
7571 binary data in lib/silccore/idcache.c.
7573 * Renamed silc_server_packet_relay_command_reply to
7574 silc_server_command_reply as it is normal packet receiving
7575 function. Rewrote the function to accept command replys for
7576 servers and not only for clients.
7578 * Mark remote router always as registered server if we are connecting
7579 to it. Otherwise, commands sent by the router to us are ignored.
7581 * All ID List find routines now returns the ID Cache Entry pointer
7582 as well if requested.
7584 * WHOIS command works now in router environment, tested with two
7585 routers, two servers and two clients.
7587 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
7588 in router environment (as it is almost equivalent to WHOIS) but
7589 hasn't been tested thoroughly. Added new functions:
7591 silc_server_command_identify_parse
7592 silc_server_command_identify_send_reply
7593 silc_server_command_identify_from_client
7594 silc_server_command_identify_from_server
7596 * Disabled route cache adding because adding two different ID's with
7597 same IP replaces the old cache entry thus giving wrong route.
7598 The entry->router->connection is always the fastest route anyway
7599 so route cache may not be needed. Of course, new routes maybe
7600 established after receiving the ID when the entry->router->connection
7601 might not be anymore the most optimal.
7603 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7605 * Add route cache for received ID for fast routing.
7607 * Added silc_server_packet_route to route received packet on router
7608 that is not destined to us.
7610 * Renamed silc_server_get_route to silc_server_route_get.
7612 * Added id_string and id_string_len fields into SilcServer to
7613 include encoded ServerID for fast comparing without excess
7614 encoding of the ID's.
7616 * Cleaned up WHOIS command on server side. Added following static
7619 silc_server_command_whois_parse
7620 silc_server_command_whois_check
7621 silc_server_command_whois_send_reply
7622 silc_server_command_whois_from_client
7623 silc_server_command_whois_from_server
7625 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
7626 arguments in command replies. All command functions should be
7627 updated to use this macro.
7629 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7631 * Minor typo fixes on command reply handling on server.
7633 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7635 * Added silc_server_command_add_to_channel internal routine to add
7636 the client to the channel after router has created the channel and
7637 sent command reply to the server.
7639 * Added generic silc_server_send_command to send any command from
7642 * Use static buffer with ID rendering instead of duplicating data.
7644 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7646 * Fixed a channel user mode bug when joining to a channel server gave
7647 everybody channel founder rights, oops.
7649 * We mark ourselves as the router of the incoming server connection
7650 if we are router ourselves. This way we can check in some packet
7651 sending functions whether it is locally connected server. For
7652 incoming router connections we put NULL.
7654 * For router sending packets locally means now always sending the
7655 packet cell wide; to local clients and local servers. For normal
7656 server sending packet locally means sending it to only local
7659 * Fixed the JOIN command to really work in router environment. If the
7660 channel is created it is always created by the router. Router is
7661 also responsible of making the initial joining to the channel,
7662 sending JOIN notify to the sending server and distributing
7663 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
7664 does not exist server doesn't do anything else but forward the
7665 command to the router which performs everything.
7667 * Added silc_server_send_channel_key function to send the Channel Key
7670 * Added silc_server_create_channel_key to create new channel key. The
7671 channel key is now re-generated everytime someone joins or leaves
7672 a channel, as protocol dictates. Note: channel->key_len is the
7675 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7677 * Splitted server.[ch] finally. Created now packet_send.[ch] and
7678 packet_receive.[ch] to separate packet sending and receiving
7679 routines. The server.[ch] now includes everything else including
7680 actual packet processing (writing and reading data) and other
7683 Renamed silc_server_private_message_send_internal to
7684 silc_server_send_private_message. The routine is still though
7685 used only to relay private messages as server does not send
7686 private messages itself.
7688 Renamed silc_server_new_channel to silc_server_create_new_channel
7689 and added new function sicl_server_new_channel that handles the
7690 incoming New Channel packet. Added also new sending function
7691 silc_server_send_new_channel to send New Channel Payload.
7693 * Added new function silc_server_notify to process incoming notify
7694 packet to the server/router. Server may then relay the notify
7695 to clients if needed.
7697 * Added new function silc_server_new_channel_user to process incoming
7698 New Channel User packet. Router will redistribute the packet and
7699 send JOIN notify to its local clients and locally connected servers
7700 if needed. Normal server will send JOIN notify to its local client
7701 on same channel when received this packet. Added also corresponding
7702 sending function silc_server_send_new_channel_user to sent the
7705 * Added boolean route argument to send_notif_to_channel and
7706 packet_send_to_channel functions to attempt to route the packet
7707 if it is TRUE and send only locally if it is FALSE.
7709 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7711 * silc_server_replace_id now broadcasts the received replace ID
7712 packet if it is not broadcast packet already. The router must
7713 broadcast to inform other routers about changed ID.
7715 * Added backpointer to server's router into SilcServer context in
7716 silcd/server_internal.h.
7718 * Fixed silc_server_packet_broadcast to send correct broadcast
7721 * The channel key is now distributed to the local client as soon
7722 as it is received from the router (in router environment) so that
7723 no other packet may be sent for the channel until client has
7726 * silc_server_remove_channel_user now broadcasts the received
7727 Remove Channel User packet if it is not broadcast packet already.
7728 The router must broadcast to inform other routers about removed
7731 * Added users field into SilcPacketContext that is a reference count
7732 of the context. One can increase the reference count by calling
7733 silc_packet_context_dup which is now changed to just increase the
7734 reference count instead of duplicating the data. The reference
7735 count is decresed by calling silc_packet_context_free that will
7736 free the data after the reference count hits zero.
7738 For now on the packet context and everything allocated into it
7739 (including the raw packet from network) must be freed by calling
7740 the new silc_packet_context_free function. Added also new function
7741 silc_packet_context_alloc that must be used now to allocate the
7742 context. This also means that if a routine is asynchronous from
7743 silc_[client/server]_packet_parse_type the packet context must
7744 be duplicated by calling silc_packet_context_dup. Otherwise it
7745 gets free'd after silc_[client/server]_packet_parse_type returns.
7746 Also, one must remember that if packet is duplicated then its
7747 reference count must be decresed by calling the free function as
7748 many times as it was duplicated.
7750 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7751 from both client and server.
7753 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7755 * Made joining to a channel working in router environment.
7757 * Cleaned up JOIN command on server side and create function
7758 silc_server_command_join_channel internal routine to make the
7761 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7763 * Changed silc_command_pending list to SilcDList. Also, added
7764 `ident' field to SilcServerCommandPending structure to identify
7765 the reply and to call correct callback.
7767 Added silc_server_command_pending_check function to replace the
7768 corresnponding macro. The silc_command_pending list is not
7771 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7772 to set identifier to previously allocated Command Payload. It
7773 is used to set identifier for command when resending Command
7776 * Added silc_command_payload_encode_payload to encode Command
7777 Payload buffer from SilcCommandPayload structure.
7779 * Added silc_argument_payload_encode_payload to encode Argument
7780 payload buffer from SilcArgumentPayload structure.
7782 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7784 * Changed WHOIS command to support router connection on server side.
7785 The whois request is always sent to router unless the server is
7786 standalone server. After server has received the reply from the
7787 router will it send the reply to the client.
7789 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7790 broadcast received broadcast packet. The function is used only
7791 by router. The broadcast packet is always sent to the router's
7794 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7795 render given ID to printable string, for log files for example.
7797 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7799 * Made basic router to router connections working. At least they
7800 can now connect to each other but nothing really works the way
7801 they are supposed - yet.
7803 * Added new initiator token to RouterConnection configuration
7804 file in silcd/serverconfig.[ch]. It is used to tell whether we
7805 are the initiator to the remote router or whether we'll expect
7806 the other end to connect.
7808 * Moved registering of listener task to silc_server_init, hence
7809 the server starts listenning as soon as it is run, even if it
7810 does not have connections to other routers. Let's see how well
7813 * Changed default connection retry timeouts for more suitable in
7816 * Removed cipher and such arguments from silc_idlist_add_client
7817 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7818 Added new function silc_idlist_add_data to add the keys and stuff
7821 * Added SilcIDListData structure and added it to SilcClientEntry
7822 and SilcServerEntry as their first field in the structure. This
7823 way we can explicitly cast the ID entries to the SilcIDListData
7824 structure and get common data for the entries. In past, we had
7825 to first check what type of connection it is and then cast it to
7826 correct ID entry type. Now, we can directly cast the opaque
7827 pointer to the SilcIDListData (no matter what ID entry it actually
7828 is) and get the data needed.
7830 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7832 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7833 in some circumstances even if threre were timeout tasks, though not
7834 IO tasks, but tasks anyway. Now fixed.
7836 * Defined SilcServerConnection structure to hold connection specific
7837 stuff about directly connected servers and routers. The definition
7838 is currently in silcd/server_internal.h. I thought about having
7839 a bit more important role fro this struct but for now it is used
7840 only when connecting to other server (or router actually).
7842 * Added connecting retry support in server when connecting to
7843 router(s). The retry feature implement exponential backoff
7844 algorithm. Also, added SilcServerParams structure to hold default
7845 parameters for server. For now, it include these retry settings
7846 and are hard coded. After server is moded to be as Silc Server
7847 Library this structure will be more important.
7849 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7851 * Changed client librarys channel->clients table to SilcList and
7852 changed code accordingly.
7854 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7856 * Changed client's channel table to SilcList and changed code
7857 accordingly. Also changed SilcChannelClientEntry to include back-
7858 pointer to the channel so that client entry can use that structure
7859 as list as well and we have fast cross-reference to the channel.
7860 This change dramatically decreased the complexity of channel
7861 handling with client entry and vice versa (removed one extra
7862 loop when searching for channel entry from many functions).
7864 * Changed server->sim from table to SilcDList and changed code
7867 * NAMES command can now be used from user interface. It will show
7868 the user list on the channel, neatly.
7870 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7871 Code now saves realname of the user if it becomes available.
7873 * Renamed configure.in to configure.in.pre and made ./prepare
7874 script to automatically add correct version string to
7875 configure.in which it creates from configure.in.pre.
7877 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7879 * NAMES command reply now shows users mode with the nickname when
7882 * Moved silc_client_ch[u]mode[_char] functions from
7883 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7884 place sucks, they are utility functions and should be in some
7887 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7889 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7892 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7896 * Added TRQ (efficient deque and list library) into lib/trq. This is
7897 a very good list library that is currently used in the SILC. Defined
7898 SilcList API over the library because I didn't like the API very
7899 much. See lib/trq/silclist.h for the API and examples of how to
7900 use the API. Fixed various places in the code to use the new
7901 SilcList API. The SilcList is meant for lists that has a structure
7902 already defined as a list. It is not suitable to add just some
7903 context to the list (in TRQ, the context is the list actually).
7905 So, I defined SilcDList that can be used for the purpose where
7906 predefined list structure does not exit. This can be used as
7907 such list. Now some context just can be added to the SilcDList.
7908 Currently this list is not used in the SILC just yet, though there
7909 are a lot places where this can replace dynamically allocated
7910 tables and I will fix these places, later, to use SilcDList.
7911 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7912 and use TRQ internally).
7914 Also fixed some annoying warning messages that the original TRQ
7915 code generated. Also minor changes to TRQ's Makefile.in.
7917 * Added support for querying by Client ID to both WHOIS and
7918 IDENTIFY commands into server, as required by the protocol.
7920 * Removed method function pointers from SilcBuffer structure. They
7921 weren't used to anything and just increased the context size for
7922 no good reason. This change also made silc_buffer_alloc and
7923 silc_buffer_free functions inline functions.
7925 * Disabled command flooding detection support until it's fixed so
7926 that it accepts commands in but does not execute them more than once
7929 * Added silc_net_localhost(), to return local hostname, into
7930 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7931 that must be initialized before calling silc_client_init.
7933 * Added new function: silc_server_send_notify_on_channels to send
7934 notify messages to all channels client has joined. It is assured
7935 that the message is sent only once per client.
7937 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7938 lib/silcutil/silcutil.[ch] as silc_format function. The new
7939 function is generic and is used by server as well, not only by
7940 the logging routines.
7942 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7943 the provided version string was not acceptable. Added new function:
7944 silc_ske_check_version into lib/silcske/silcske.h. The function
7945 must be implemented by the application (client or server) and it
7946 does not reside in the SKE library. The function checks the version
7947 string remote end sent.
7949 * Added back pointers (to opaque context and to SilcSocketConnection)
7950 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7952 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7953 duplicate packet context structure.
7955 * Changed `notify' client operation to send same arguments as client
7956 receives from server except for ID's. ID's are mapped to correct
7957 ID entry and that is returned. Also, if channel entry is not sent
7958 by server but the notify is for channel the channel entry is sent
7959 to application (otherwise application doesn't know that it is for
7960 channel (library gets it from packet's Destination ID)).
7962 * Added silc_client_remove_from_channels into client library to
7963 remove a client from all channels it has joined to. Used when
7964 received SIGNOFF notify from server. Added also new function
7965 silc_client_replace_from_channels to replace old ID entry with
7966 new ID entry on all channels. Used when received NICK_CHANGE
7969 * Fixed ID Cache list handling in silc_idlist_get_client in
7970 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7971 to get (or query) client by ID.
7973 * Updated TODO list.
7975 * Added connection authentication status message defined by the
7976 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7977 support for these into the code in client and server side.
7979 * Added generic function silc_client_send_command to send any command
7980 with variable argument list. Application should use this function
7981 to send commands if the command functions provided by the library
7982 does not suite for the application's user interface needs.
7984 * Added new `failure' client operation. Application is notified about
7985 received failure packet if client is executing a protocol. In this
7986 case the protocol's execution has failed.
7988 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7989 is required by the protocol.
7991 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7992 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7995 * Added status flag to SilcSKE object to indicate realtime status
7996 of the SKE protocol.
7998 * Application receives now exactly same command reply arguments as
7999 the library receives from server. However, if ID is received the
8000 corresponding ID entry is returned to the application (eg. Client
8001 ID is mapped to correct SilcClientEntry entry and that is returned).
8002 Changed command_reply client operation due to this change.
8004 * Changed all ID's in commands and in command replys as ID Payloads.
8005 Change affected both client and server side codes.
8007 All ID's sent in SILC network (with execption of ID's in SILC
8008 Packet header) are sent in ID Payload to support variable length
8011 * Server now notifies nick changes and notifies all clients on
8012 the channels about the new nickname (about the new Client ID,
8015 * Implemented CMODE command to change channel modes. Supports all
8016 channel modes defined by the protocol specs except ban and invite
8017 lists. (Also, private channel key mode is supported but support for
8018 setting private channel key in client is missing, thus, this mode
8019 has no effect on client side (except that server requires that the
8020 client uses private channel key and normal channel traffic does not
8023 Also, invite mode works per se, but INVITE command does not work
8024 yet correctly, so you can set channel as invite only channel but
8025 inviting clients to the channel does not work (it is yet to be
8026 thought what's the best way to do it).
8028 * Added new command SILC_COMMAND_CUMODE to change user mode on the
8029 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
8030 Implemented CUMODE command to change user's mode on the channel.
8031 Supports all modes defined by the protocol specs.
8033 * Added NAMES command reply to return users modes on the channel.
8035 * Removed unnecessary and slow ciphers from lib/silccrypt.
8037 * Set SO_KEEPALIVE option to connection sockets by default.
8039 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
8041 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
8042 redefined the Notify Payload into protocol specs.
8044 * Added silc_id_payload_parse_id to get ID directly from raw
8047 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8049 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
8050 accept searching by Client ID as well.
8052 * Added support for LEAVE and SIGNOFF notify types in client library.
8054 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
8055 to parse ID Payload from raw data.
8057 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8059 * Added flags parameter into silc_ske_assemble_security_properties
8060 function in lib/silcske/silcske.[ch].
8062 * Changed notify client operation to fit better for notify messages
8063 sent by server. The notify payload received from server is now
8064 passed to the application (after parsing it to SilcNotifyPayload).
8065 It is application's responsibility to retrieve the arguments
8066 from the payload and show the message the way it wants. The message
8067 sent by server is implementation specific.
8069 * Changed public keys to comply with the protocol specification.
8070 Old public keys are not supported anymore and are not compatible.
8072 * Removed nickname from Channel Payload as the latest draft removed
8073 it. The client must resolve the nickname from the NAMES command
8074 reply received when it joined the channel.
8076 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
8078 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8080 * Fixed some errors in protocol specification drafts.
8082 * Created lib/silccore/silcnotify.c to implement Notify Payload
8083 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
8084 generic payloads described by protocol specifications. The file
8085 includes implementations for ID Payload and Argument Payload.
8087 * Changed Command Payload implementation to use the new Argument
8088 Payload. Changed command_xxxx_payload to command_payload_xxxx
8089 to comply with SILC coding conventions.
8091 * Added suppport for Argument Payload handling in Notify Payload
8092 implementation as protocol requires it. Added the new support
8093 into server and client lib as well.
8095 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8097 * Added support for multiple nicknames on same channel. [n] is
8098 added locally to the nickname if there are more than one same
8099 nicknames on the channel.
8101 * Server now sends all nicknames that matched WHOIS request.
8102 Client also shows the list received from server.
8104 * Added TOPIC command to client side. User can now set and show
8105 current topic on channel.
8107 * Added MOTD command to client and server. Also, server sends the
8108 motd when client connects to the server.
8110 * Changed version strings to comply ISO 8601.
8112 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8114 * Fixed protocol error handling in client library. It should now
8115 cope even if the SKE fails for some reason.
8117 * Made new protocol specification drafts for submitting to IETF.
8119 * Implemented TOPIC command to server in silcd/command.c.
8121 * Added two new notify types into lib/silccore/silcnotify.h:
8122 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
8123 notify nickname change and topic setting/change on a channel.
8125 * API change of command_reply operation in client library. The
8126 application gets now the status type received from server as well.
8128 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8130 * Removed the function just added to lib/silcutil/silcschedule.[ch].
8132 * Cras fixed and optimized the packet handling even further and
8133 it should work now. Minor change to the prototype of function
8134 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
8136 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8138 * Added new function into lib/silcutil/silcschedule.[ch]:
8139 silc_schedule_with_fd to select() a specified fd. The function
8140 returns after timeout expires or data arrives or goes. The
8141 function is used by packet routines to wait that all data is
8142 received from network.
8144 * Fixed data reading from network in lib/silccore/silcpacket.c.
8145 The code now assures that all data is read from the fd and then
8146 continues packet processing. This was a bug fix since the code
8147 used to drop some data in some circumstances.
8149 * Added new function into lib/silcclient/client.[ch]:
8150 silc_client_start_key_exchange to start key exchange after
8151 connection has been established to server. The code internally
8152 now uses this funtion but its main purpose was to provide it
8153 for applications that perform their own connecting. After
8154 application has created a connection it merely calls this
8155 function to start the key exchange between client and server.
8156 The library takes care of everything else after that.
8158 Updated also lib/silcclient/README to explain the usage of
8161 * Do not send to application information that connection has
8162 been established. Application gets notified it by connect
8165 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8167 * Applied cras's patch to add silc_schedule_one function. The
8168 function runs scheduler once and returns.
8170 * Fixed the scheduler after cras messed it up. The timeout
8171 handling works now as it's supposed to work.
8173 * Added into lib/silccore/ silcnotify.h to include notify
8174 message types support. Changed silc_server_send_notify*
8175 functions, in server.[ch], to support those new notify types.
8176 Added the support for the notify types into client library,
8177 as well. Added new notify client operation into ops.h in
8180 * Changed silc_server_packet_send_to_channel to send normal
8181 packets instead of just channel message packets. The function
8182 is now used to send the notify packets to channels. It is not
8183 used to send channel message packets anymore, as server never
8186 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
8187 va_arg()s as it seems to require it nowadays. I guess, if SILC
8188 is compiled with older va_arg() the new code should work anyway.
8190 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8192 * Splitted core library. Core library (lib/silccore) includes
8193 now only SILC protocol specific core (and common) components.
8194 Created new utility library (lib/silcutil) that includes more
8195 generic purpose stuff. The stuff for util library was taken
8196 from the old core library. This was minor and easy split.
8198 * Created SILC Client Library (lib/silcclient) that includes
8199 implementation of the SILC client without user interface. This
8200 was major move from silc/ directory. The code has been changed
8201 so that it is transparent towards the user interface. The
8202 silc/ directory includes now the same user interface as before
8203 and it uses the new client library. Read lib/silcclient/README.
8204 Basicly, the client library performs everything else related
8205 to SILC except user interface handling. Also, configuration
8206 files are considered to be part of user interface and library
8207 does not handle them.
8209 This change also changed a lot of structures, function naming etc.
8210 Most important change was that SilcClientWindow object was
8211 renamed to SilcClientConnection in the client library. Created
8212 also new file lib/silcclient/ops.h. Also added new files
8213 silc/local_command.[ch] and silc/client_ops.[ch].
8215 All these changes were made to make it easier for user interface
8216 designers to create what ever user interface for the SILC client
8219 It is also expected that the server will be moved to lib
8220 directory as well and SILC Server Library will be created;
8221 sometimes in the future.
8223 * Removed Local commands from lib/silccore/silccommand.h as
8224 they are application specific and new client library does not
8225 handle any of those anymore.
8227 * Several functions moved to lib/silcutil/silcutilc.[ch] from
8228 old client implementation in silc/.
8230 * Added support for callback functions in SILC_LOG_* macros.
8231 Application can now set its own callbacks that will be called
8232 instead of using the default functions that will always print
8233 the debug messages to stderr (or stdout). Also, debugging can
8234 now be disabled by setting silc_debug to FALSE and re-enabled by
8235 setting it to TRUE. Note, that logging will still work even
8236 if debugging is disabled.
8238 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
8239 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
8240 silc_log_reset_debug_callbacks.
8242 * To enable debugging in silc client one must give now -d
8243 option on command line.
8245 * Changed silc_schedule_init to automatically allocate task queues
8246 if they are not allocated before calling it.
8248 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8250 * Added GMP 3.1 into math library.
8252 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8254 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
8255 a channel in SILC network. The packet is used by servers and
8256 routers to notify other routers that user has left a channel.
8257 This little feature was missing until now. Added the feature
8258 to protocol specification as well.
8260 Added functions: silc_server_send_remove_channel_user and
8261 silc_server_remove_channel_user into server.[ch].
8263 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
8264 lib/silccore/silcpacket.h. However, they are not implemented
8267 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8269 * Fixed joining to a channel and sending channel messages
8270 between server and router. The channel message sending should
8271 now work inside a cell.
8273 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8275 * Fixed the private message sending between server and router.
8276 The private message sending should now work inside a cell.
8278 * Added silc_server_replace_id into server.[ch] to replace
8279 existing ID in the SILC network.
8281 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
8282 and silc_idlist_replace_server_id into idlist.[ch] in server.
8284 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8286 * Fixed the server to server connections. Server can again now
8287 connect to router. Router to router connections probably does
8290 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8292 * Added dynamic protocol registering support. Now protocols can
8293 registered and unregistered on the fly. Patch by cras.
8295 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8297 * Added lib/contrib directory to hold routines that some platforms
8298 don't have but are needed by SILC.
8300 * Added getopt.c, getopt1.c and getopt.h from GNU C library
8301 into lin/contrib to provide getopt() and getopt_long() for
8302 those who don't have it.
8304 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8306 * Added AWAY command to client. When away message is set and
8307 client receives a private message packet the client automatically
8308 replies to the sender with the away message.
8310 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
8311 bug seemed to be the cause of recent problems when compiling
8314 * Added version detection support to SKE protocol specification
8315 and added the new changes to the SKE implementation as well.
8316 There were other minor changes in the SKE protocol as well.
8318 Many changes in lib/silcske/silcske.[ch] and in
8319 lib/silcske/payload.[ch].
8321 * Added ^U functionality, clear input line. Patch from cras.
8323 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8325 * Mainly small bugfixes on core library. Fixed some debugging
8326 logging and buffer overflow in silclog.c.
8328 * Updated config.sub and config.guess on the distribution tree.
8330 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8332 * Added command lagging support in server. Client may execute
8333 commands now only once in two seconds.
8335 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8337 * Optimized packet reception. MAC computation and checking is now
8338 also more optimized. A lot previously duplicated code is now
8339 used as generic by both client and server.
8341 * Fixed key pair generation in clientutil.c
8343 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8345 * Added into lib/silccore/silcbufutil.[ch] new function;
8346 silc_buffer_realloc.
8348 * Moved generic packet sending/encryption functions to
8349 lib/silccore/silcpacket.[ch] from client and server. Some
8350 rewriting of the functions.
8352 * Moved all generic packet reception/decryption functions to
8353 lib/silccore/silcpacket.[ch] from client and server. The
8354 packet processing is now much cleaner in both client and server.
8355 These were major changes in both client and server.
8357 * Created many common functions in server to do packet sending.
8358 Previously code were duplicated a lot, this has been removed
8361 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8363 * Rewrote major parts of the ID cache system. Don't know
8364 whether it is better now or not but at least the API is more
8367 * Major rewrite on ID cache stuff on client because of the ID
8368 cache API changes. Added idlist.c to client.
8370 * Also major rewrite on ID cache stuff on server as well.
8371 Major rewrite of idlist.[ch]. SilcXXXList's are now named
8372 SilcXXXEntry's. We won't keep anymore idlist specific pointers
8373 in hand, instead they are all put into the ID cache system now.
8374 All server_idlist_* routines uses ID cache now instead of
8375 traversing its own lists (those lists does not exist anymore).
8376 SilcIDList though still exists. Also, SilcXXXEntry's are
8379 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8381 * Finally made the SKE implementation compliant to the protocol
8382 specification. All mp integers are now binary encoded as
8383 opposed being HEX encoded.
8385 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
8388 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
8389 functions: silc_[encode/decode]_pem. Also added function
8390 silc_encode_pem_file to PEM encode with newlines ('\n') for
8393 * SILC public keys are now encoded either PEM or binary. Same
8394 option is for private keys as well. By default private keys
8395 are binary encoded and public keys PEM encoded. Silly HEX
8396 encoding were removed.
8398 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
8399 function to create fingerprints.
8401 * Fixed a bug in SHA1; does not change the original data anymore.
8403 * Partly implemented INFO command on client and server side.
8404 Fixed CLEAR command. Changes to SERVER command; show current
8405 server(s) when giving command without arguments. Added
8406 VERSION command to client.
8408 * Added check to server that unregistered connections cannot
8409 execute commands (unless it is specificly allowed).
8411 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8413 * Fixed screen refresh.
8415 * Fixed channel joining bug from client. On some circumstances
8416 client tried to join to a channel it had already joined.
8418 * Added public key verification process into client's protocol.c.
8419 The client now verifies the public key from user and saves
8420 it into ~./silc/serverkeys/ directory.
8422 Added into: clientutil.[ch]: silc_client_verify_server_key.
8424 * Changed SKE protocol's silc_ske_initiator_finish function
8425 to accept callback function that verifies the received public
8426 key. Removed old silc_ske_verify_public_key function.
8428 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8430 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
8431 silc_pkcs_private_key[_data]_set.
8433 * Made the password and public authentication more cleaner in
8434 server's protocol.c.
8436 * Removed historic and obsolete protocol `channel_auth' from
8437 both client and server.
8439 * Removed wrong way of sending command status messages from
8440 server to client in server's command.c. The old way violated
8441 protocol specification.
8443 Changes to silccore/silccommand.[ch]: removed
8444 silc_command_encode_status_payload -> not needed anymore,
8445 changed silc_command_encode_payload_va to accept extra
8446 argument on variable argument list. The argument type must
8447 now be provided to the function. Also, added new function:
8448 silc_command_encode_reply_payload_va which is same as
8449 normal command_encode_payload_va except command status type
8450 is provided as extra argument.
8452 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8454 * Added ~./silc directory handling. The directory includes the
8455 public and private keys for the client.
8457 Added silc_client_check_silc_dir, silc_client_create_identifier
8458 and silc_client_load_keys.
8460 * Implemented SILC protocol compliant public key. Added public
8461 and private key saving to and loading from files.
8463 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
8464 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
8465 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
8466 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
8467 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
8469 Implemented: silc_pkcs_save_[public/private]_key[_data] and
8470 silc_pkcs_load_[public/private]_key.
8472 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8474 * Added silc_server_get_route (route.[ch]) to get connection
8475 data for the fastest route for given ID.
8477 * Implemented INVITE command on client and server. The command
8478 were re-defined in the SILC Protocol Specification and the
8479 implementation now complies with the specification.
8481 * Implemented PING command on client and server.
8483 * Implemented NAMES command on client and server. The server side
8484 supports currently only normal server not router server yet.
8485 Some changes to NAMES definition in SILC protocol specification.
8487 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8489 * Implemented LEAVE command on client and server.
8491 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
8492 again. This change was made to the protocol as well. Server
8493 should not violate the protocol specification anymore.
8495 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8497 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
8498 was tested. SOCKS4 was not but should work anyway.
