519 to application. Affected files are lib/silcclient/client.c
520 and lib/silcclient/silcclient.h.
522 * Rewrote the text for Private Message Key Payload in the
523 protocol specification. Protocol TODO #11.
525 Wed Apr 3 16:24:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
527 * Upgraded the protocol version to 1.1, updated protocol specs
530 * Added the nickname as new argument to NICK_CHANGE notify and
531 added it to protocol specs and implemented it to client and
532 server. Protocol TODO #3. Affected files are silcd/idlist.[ch],
533 silcd/command.c, silcd/packet_receive.c, packet_send.[ch], and
534 lib/silcclient/client_notify.c.
536 * Added the killer's client ID to the KILLED notify and added
537 it to protocol specs and implemented it to client and server.
538 Protocol TODO #13. Affected files are silcd/command.c,
539 silcd/packet_receive.c, packet_send.[ch],
540 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
541 The killer's client entry is now returned to application in
542 the `notify' client operation.
544 * Fixed the Max Argument fields that had too large value set
545 in the protocol specs. Protocol TODO #14.
547 * Added the LEAVE command reply to return the ID of parted
548 channel. Updated protocol specs and implemented it to the
549 client and server. Protocol TODO #15. Affected files are
550 silcd/command.c, lib/silcclient/command_reply.c. The channel
551 entry is now returned to application in the `command_reply'
554 * Rewrote the version SKE version checking in client libary
555 and in server to use the silc_parse_version_string. Affected
556 files are lib/silcclient/protocol.c, silcd/protocol.c.
558 * Added SILC_STATUS_ERR_NO_CHANNEL_FOPRIV error status to few
559 commands that was missing it, and updated protocol specs and
560 the server implementation. Protocol TODO #10. The affected
561 file is silcd/command.c.
563 * Defined new message flags SILC_MESSAGE_FLAG_REPLY to be
564 generic reply to a generic request (REQUEST flag), and
565 SILC_MESSAGE_FLAG_DATA to send any kind of data in a generic
566 way. A draft-riikonen-silc-flags-payloads-00.txt is written
567 to define the payload for DATA flag. Added the flags to
568 the implementation. Protocol TODO #9. Affected file is
569 lib/silccore/silcchannel.h.
571 Changed the client library to return the message length
572 to application as well in the channel_message and private_message
573 client operations. Affected files are
574 lib/silcclient/client_prvmsg, lib/silcclient/client_channel.c,
575 lib/silcclient/silcclient.h, irssi/src/silc/core/client_ops.c,
576 and lib/silcclient/client_ops_example.c.
578 * Added two new channel modes: SILC_CMODE_SILENCE_USERS
579 and SILC_CMODE_SILENCE_OPERS which can be used to moderate
580 the channel. Updated protocol specs and impelemented this
581 to client and server. Protocol TODO #6. Affected files are
582 silcd/packet_receive.c, server_util.c, lib/silcclient/command.c,
583 lib/silcclient/client_channel.c, lib/silccore/silcmode.h.
585 Added new options m and M to CMODE command in Irssi SILC
586 client to set these modes.
588 * Deprecated all administrative commands from SILC protocol
589 since they are highly implementation specific commands.
590 Updated protocol specs. Moved the old commands in
591 implementations to private range of command types. Affected
592 files are silcd/command.c, lib/silcclient/command.c and
593 lib/silcclient/command_reply.c. Protocol TODO #8.
595 * Fixed a bug in server where sending unknown command crashes
596 the server. Affected file silcd/command.c.
598 Wed Apr 3 09:57:47 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
600 * Added SILC_PROTOCOLVERSION macro to check protocol version
601 of a socket connection. The affected file is
602 lib/silcutil/silcsockconn.h.
604 * Added better error logging in rekey protocol. Affected file
607 * Do not check public key types in SKE during rekey. Affected
608 file lib/silcske/payload.c.
610 * Fixed the rekey protocol with PFS, which was totally broken.
611 Affected file silcd/protocol.c.
613 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
615 * Some client implementations quit network by doing first LEAVE
616 and then immediately SIGNOFF (like Bombyx). We now do check
617 after a short time after LEAVE notify and check whether the
618 client is still valid after LEAVE, and if not we remove it from
619 cache. Affected file is lib/silcclient/client_notify.c.
621 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
623 * Merged version 1.1.4 of zlib. Even if it not currently in use,
624 it's good not to have security holes here.
626 * Fixed a negative refcount situtuation for the config context.
627 Affected file is silcd/serverconfig.c.
629 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
631 * ROBOdoc documented lib/silcutil/silcutil.h.
633 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
635 * Optimized even more the SilcPacketContext structure. Now
636 totally saved 16 bytes of memory per context after optimization.
637 Affected files are lib/silccore/silcpacket.[ch].
639 * Made strict checks for valid SILC IDs. Affected file is
640 lib/silccore/silcid.c.
642 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
644 * Changed the object argument for silc_cipher_register,
645 silc_hash_register, silc_hmac_register and silc_pkcs_register
646 to const. Affected files are lib/silccrypt/silccipher.[ch],
647 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
649 * Changed the silc_get_username and silc_get_real_name to
650 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
652 * Fixed the Irssi SILC Client to use the silc_get_username and
653 silc_get_real_name insted of glib routines since the glib
654 routines only corrupt stack. Fixes the Irssi SILC to work in
655 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
657 * Fixed the Irssi to not use g_get_home_dir since it crashes
658 or returns garbage on cygwin and corrupts stack. Added function
659 get_home_dir to Irssi routines. Affected files are
660 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
662 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
664 * Made some structure optimizations. SFTP memory FS MemFSEntry
665 entry structure. Optimized SilcTask structure. Optimized
666 SilcPacketContext structure.
668 Affected files lib/silcsftp/sftp_fs_memory.c,
669 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
671 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
673 * And yet again reverted back the config thing since Johnny
674 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
677 * Fixed memory leaks from config object. Affected files are
678 silcd/serverconfig.[ch].
680 * Added support for adding new connections to the server in rehash.
681 After rehash they take effect.
683 Added support for changing the maximum allowed connections in
684 rehash. The number can grow but going smaller is not supported.
686 Added function silc_server_num_sockets_by_remote to the
687 silcd/server_util.[ch].
689 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
691 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
693 * Added preliminary checking during config parsing for a valid
694 public/private key and removed further checks in the code.
695 Affected files are silcd/serverconfig.[ch], server.c.
697 * Moved functions silc_server_drop() and silc_server_daemonise()
698 from server.c to silcd.c since they are stricly related to
699 the application activity.
701 * Reverted a small part of the automatic ref/unref since
702 it caused a double unref in some situations. Affected
703 files are silcd/silcd.[ch], server.c, serverconfig.c.
705 * Added some .cvsignore files in the lib directory.
707 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
709 * Fixed silc_net_gethostbyaddr to correctly resolve by
710 address. Affected file lib/silcutil/silcnet.c.
712 * Fixed the notify relaying to client. The HMAC to be used
713 with relayed packets ws wrong and caused decryption failure
714 at the client end. Affected file is silcd/packet_receive.c.
716 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
718 * Created new branch silc_protocol_1_0_branch.
720 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
722 * Changed the silc_server_config_* routines to be SilcServer
723 independent. They are now officially application specific code
724 and not part of generic server implementation. Affected files
725 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
727 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
729 * Added automatic referencing of config context in the
730 silc_server_config_alloc, and automatic unreferencing in the
731 silc_server_config_destroy. Affected files are
732 silcd/serverconfig.[ch], silcd/silcd.c.
734 * Fixed the silc_log_quick handling in the logging routines.
735 It didn't log quickly when it was TRUE. Affected file is
736 lib/silcutil/silclog.c. Also the flush delay was set even
737 if it was 0 in config file. Affected file is
738 silcd/serverconfig.c.
740 * Added support for changing key pair of the server in rehash.
741 Affected file silcd/server.c.
743 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
745 * Fixed the TOPIC_SET notify to not cras. It changed the topic
746 too early, before getting the channel entry. Affected file
747 is silcd/packet_receive.c.
749 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
751 * Added functions silc_server_config_[ref/unref], these are used
752 to prevent that the config object is destroyed.
754 No longer directly affect global variables silc_log_quick and
755 silc_log_delay, they are first cached inside the config object
756 and then applied with silc_server_config_setlogfiles().
758 silc_server_config_set_defaults() is now internal to
759 serverconfig.c, there are no reasons to show this internal stuff
762 Affected files are silcd/serverconfig.[ch].
764 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
765 fprintf's to stderr, since some code may be executed again after
766 the server went into the background. Affected files are
769 * Added rehash support. Added function silc_server_rehash() that
770 will perform all the basic tasks of the rehashing procedure.
772 * Added command line option `-x, --hexdump'. This will enable the
773 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
774 The option `--hexdump' implies `--debug'.
776 * Fixed a bad bug in the logging APIs (silcutil library) where
777 the application would crash after calling silc_log_reset_all().
779 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
781 * Fixed the KICKED notify handling in client library to
782 correctly remove the channel and all entries from the
783 channel when I was kicked. This bug crashed the client.
785 Fixed yet another but in KICKED notify handling to remove
786 the kicked client correctly from the channel.
788 Affected file is lib/silcclient/client_notify.c.
790 * Fixed a minor bug in looking up correct client entry
791 in KICKED notify in server. Affected file is
792 silcd/packet_receive.c.
794 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
795 sources correctly to distribution. Fixes --with-gmp option.
797 * Removed the manual rehashing from ID Cache, and changed it
798 to use the SILC Hash Table's auto rehash feature. Affected
799 file is lib/silccore/silcidcache.c.
801 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
803 * Fixed a bug in the silc_client_nickname_format function that
804 handles the multiple same nickname formatting. Two clients
805 with same nickname caused problems after the first one left
806 and rejoined. It didn't format the nickname correctly.
807 Affected file is lib/silcclient/idlist.c.
809 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
811 * Don't change the topic if olod topic is same as new one.
812 Affected file is silcd/packet_receive.c.
814 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
816 * Added cross-reference support to the SILC Documentation
817 generator. All types across all HTML files are now cross-
818 referenced. Affected files util/robodoc/generator.c and
819 scripts/silcdoc/silcdoc.
821 * Added file lib/silcutil/silctypes.h to include all the
822 arithmetic type definitions and some macros. Removed
823 includes/bitmove.h and moved macros to silctypes.h.
825 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
827 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
829 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
831 * Added `type' argument to silc_id_payload_parse_id function which
832 now returns the type of the ID to the sent pointer. Affected
833 file is lib/silccore/silcid.[ch].
835 * Added check for CMODE_CHANGE notify type that mode change is
836 allowed by the sender. Affected file silcd/packet_receive.c.
838 * Added check for CUMODE_CHANGE notify type that mode change is
839 allowed by the sender. Affected file silcd/packet_receive.c.
840 Added the ID type as CUMODE_CHANGE notify type as argument
841 to the `notify' client operation. Affected files are
842 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
844 * Added function silc_client_add_server to the client library.
845 Added support for resolving also channel and server info when
846 received unknown entity in notify packet. Affected files are
847 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
849 * Added function silc_command_get_status to return the command
850 status from the command reply's argument payload. Affected files
851 are lib/silccore/silccommand.[ch].
853 * Added check for KICKED notify type that the kicking is
854 allowed by the client. Affected file silcd/packet_receive.c.
856 * Created function silc_get_input which can be used to get input
857 (echo on or off) from user on command line. Affected files are
858 lib/silcutil/silcutil.[ch].
860 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
862 * Optimized silc_server_packet_relay_to_channel function.
863 Added new function silc_channel_message_payload_encrypt which
864 can be called directly if channel message payload needs to
865 be encrypted and is already encoded (no need to call _encode
866 function). Packet relaying is now done by router without any
867 extra memory allocations. Affected files are
868 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
871 * Fixed the INVITE notify handling. It took wrong arguments
872 as invite list and invite delete. Affected file is
873 silcd/packet_receive.c.
875 * Added check for TOPIC_SET notify type that the topic change is
876 allowed by the client. Affected file silcd/packet_receive.c.
878 * Added check for INVITE notify type that inviting is allowed by
879 the client. Affected file silcd/packet_receive.c.
881 * Changed the silc_server_client_on_channel to return the
882 SilcChannelClientEntry as well. Moved the function
883 silc_server_check_cmode_rights to server_util.[ch].
884 Affected files are silcd/server_util.[ch], silcd/command.c.
886 * Added function silc_server_check_umode_rights to check whether
887 changing client's user mode is allowed. Added check for
888 UMODE_CHANGE notify type that the umode change is allowed
889 by the client. Affected files are silcd/server_util.[ch],
890 silcd/packet_receive.c and silcd/command.c.
892 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
894 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
895 ID length. It ignored that ID can be IPv6 based as well.
896 Affected file lib/silccore/silcpacket.h.
898 * Fixed the silc_id_id2str and silc_id_str2id to take the
899 IPv6 address offset's into consideration. Affecte file is
900 lib/silccore/silcid.c.
902 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
904 * Fixed the internal Unix scheduler functions to check for
905 NULL context they may receive. The affected file is
906 lib/silcutil/unix/silcunixschedule.c.
908 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
910 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
911 can specify different directory with --home command line
912 parameter. Affected files irssi/src/silc/core/client_ops.c,
915 * SILC-specific commands aren't now executed if the active server
916 isn't of SILC-type, so there won't be problems with having
917 IRC and SILC protocol support in same client. Affected files
918 irssi/src/silc/core/silc-channels.c, silc-servers.c,
921 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
923 * Improved the signal support in SILC Schedule. Added new
924 function silc_schedule_signal_call which is used by application
925 to mark a signal to be called. It is now safe to perform
926 any kind of tasks in signal callbacks since it is guaranteed
927 that the application specified signal callback is called
928 after the signal is over. Affected files are
929 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
931 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
933 * Added `name' field to SilcChannelPrivateKey to represent
934 application given name for the key. Moved also the context from
935 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
936 Added the `name' argument also to the function
937 silc_client_add_channel_private_key.
939 Added function silc_client_current_channel_private_key to set the
940 current channel private key in use.
942 Added "change" command to KEY command which can be used to change
943 the current channel private key. Bound the command also to
946 Also affected files lib/silcclient/client_channel.c,
947 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
949 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
951 * Added silc_rng_get_byte_fast function in to the
952 lib/silccrypt/silcrng.[ch].
954 * Changed the interface of silc_packet_assemble and the
955 silc_packet_send_prepare. If silc_packet_assmble is now
956 called the application does not call silc_packet_send_prepare
957 because the library will call it automatically. These
958 interfaces now also return a reference to the outgoing buffer
959 which includes the assembled packet, which the application can
960 use to encrypt the packet.
962 Affected files are lib/silccore/silcpacket.[ch],
963 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
964 silcd/packet_send.c, server_backup.c and packet_receive.c.
966 * Fixed a packet sending bug on very high load, where outgoing
967 packet queue wasn't handled correctly and packets got corrupted.
968 Affected files are lib/silcutil/*/silc*sockconn.c,
969 lib/silcclient/client.c and silcd/server.c.
971 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
973 * Added macro SILC_PACKET_DATALEN which can be used during
974 packet assembling to check whether the data to be added to
975 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
976 len is truncated until it fits it.
978 Added checks for maximum length of channel message payload and
979 private message payload also.
981 Added checks for maximum packet length in server and in
984 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
985 lib/silcclient/client.c, lib/silccore/silcchannel.c and
986 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
987 lib/silcclient/client_prvmsg.c.
989 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
991 * Added silc_server_packet_queue_purge call to the
992 silc_server_disconnect_remote to assure that all data in the
993 queue before disconnecting is sent to the network. Affected
996 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
998 * Added the deleting of server's own ID cache entry to the
999 silc_server_free function. Free also everything else that
1000 has been allocated in silc_server_init. The affected file
1003 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1005 * Added functions silc_parse_version_string, silc_version_to_num,
1006 and silc_ske_parse_version to parse SILC protocol style version
1007 strings. Affected files lib/silcutil/silcutil.[ch] and
1008 lib/silcske/silcske.[ch].
1010 * Added new configuration params: version_protocol, version_software
1011 and version_software_vendor to specify what version the remote
1012 host must at least be to be able to connect to server. The vendor
1013 string can be regex matched too. Added new function
1014 silc_server_connection_allowed to check maximum number of allowed
1015 connections, and allowed versions for incoming connections.
1016 Affected files are silcd/server.c, server_util.[ch] and
1019 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1021 * Added preliminary support for signals in scheduler. The
1022 signals we care about are now blocked always when the scheduler
1023 is locked. This way we can synchronise the use of signal with
1024 scheduler. It is guaranteed that when signal occurs the scheduler
1025 is not locked, and thus new tasks can be safely added to the
1028 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
1029 to silc_schedule_internal_init and silc_schedule_internal_uninit.
1030 Added new platform specific routines
1031 silc_schedule_internal_signals_[un]block and
1032 silc_schedule_internal_signal_[un]register.
1034 Added new functions to SILC Schedule API:
1035 silc_schedule_signal_[un]register. Each signal that application
1036 is going to use should be registered to the scheduler.
1038 Affected files are lib/silcutil/silcschedule.[ch],
1039 lib/silcutil/*/silc*schedule.c.
1041 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1043 * Check for unauthenticated client and server in the
1044 silc_server_new_client and silc_server_new_server functions.
1045 Affected file silcd/packet_receive.c.
1047 * Added function silc_string_is_ascii to check whether given
1048 string is 7-bit ASCII string. Affected files are
1049 lib/silcutil/silcutil.[ch].
1051 * Added function silc_id_is_valid_server_id into the
1052 silcd/serverid.c and added checking for valid Server ID's in
1053 silc_server_new_server. The Server ID must always be based
1054 on the server's public IP address.
1056 * Added logging of DISCONNECT packet message in the server.
1057 Affected file silcd/server.c.
1059 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1061 * Changed all library interfaces that use Global RNG to also
1062 accept SilcRng as argument. Affected files are
1063 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
1064 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,

1066 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
1067 lib/silccrypt/rsa.c.
1069 * Added function silc_pkcs_generate_key to the
1070 lib/silccrypt/silcpkcs.[ch] for applications so that they
1071 don't need to do pkcs->pkcs->init calls anymore.
1073 * Remove SilcSocketConnection from the SFTP API since it really
1074 wasn't needed there. The application has the information
1075 saved in its contexts anyway and the SFTP layer doesn't need
1076 know about it. Affected files lib/silcsft/silcsftp.h and
1077 lib/silcsftp/sftp_[server/client].c.
1079 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].

1083 lib/silcutil/silcutil.c.
1085 * On EPOC the global crypto module lists are not used at all
1086 in the crypto library. Added support for using the constant
1087 algorithm list on EPOC. Affected files are
1088 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
1091 * Fixed the handling of third parameter of KICKED notify, since
1092 it was mistakenly updated to SILC Protocol 1.0 even though it
1093 is to be included in 1.1. Since it is not in 1.0 it is not
1094 mandatory, and this fix now handles it only if it is provided,
1095 and it is not error if it is not provided. Affected file
1096 lib/silcclient/client_notify.c.
1098 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1100 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
1101 client. Affected file irssi/src/silc/core/client_ops.c.
1103 * Merged with Irssi 0.8.4 from irssi.org CVS.
1105 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1107 * Check for valid socket connection in client entries before
1108 sending any messages. Fixes a crash, but doesn't fix some
1109 other underlaying bug that is lurking there. Affected
1110 file silcd/packet_send.c.
1112 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
1114 * $usermode, $cumode and $cumode_space expandos shouldn't do
1115 anything with non-SILC server records. Affected file
1116 irssi/src/silc/core/silc-expandos.c
1118 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1120 * Fixed the silc_net_check_[host/local]_by_sock to support
1121 IPv6 bound sockets as well. Now they can return IPv6 addresses
1122 as well. Affected file lib/silcutil/silcnet.c.
1124 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
1125 Affected lib/silcutil/unix/silcunixnet.c.
1127 * Fixed ID rendering (at least on some platforms, not NetBSD)
1128 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
1130 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1132 * Added silc_hash_public_key and silc_hash_public_key_compare
1133 functions to be used with SilcHashTable. They can be used to
1134 hash public keys and compare public keys in hash table. Affected
1135 file lib/silcutil/silcutil.[ch].
1137 * Added support for specifying multiple public keys for Client
1138 connection section in server configuration file. This makes it
1139 possible to accept multiple public keys from same host, or to
1140 make a section that accepts any incoming host, and have the
1141 accepted public keys listed in the section.
1143 Added functions silc_sever_[find/get]_public_key, added the
1144 support for this actually to all connection sections but only
1145 the Client section is currently allowed to specify multiple
1148 Affected files are silcd/server.c, server_internal.h,
1149 command.c, protocol.c, server_util.[ch], packet_receive.c.
1151 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1155 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1157 * If silc_debug is TRUE, also output standard logging messages
1158 to stderr with the debug output.
1160 Made silc_log_reset_all() flushing all channels before returning.
1161 Also fixed some documentation typos.
1163 Affected files are lib/silcutil/silclog.[ch].
1165 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1167 * Fixed the server to check correctly the amount of connections
1168 from single host, by checking also the type of the connection.
1169 Fixed also the comparison of number of connections and number
1170 of allowed connections. Affected files are silcd/server.c,
1173 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1175 * Fixed the USERS command reply to save the user's mode on the
1176 channel as well. Fixed JOIN command reply to check whether a
1177 client is on channel already and not join it twice. Affected
1178 file lib/silcclient/command_reply.c.
1180 * Added new file silc-expandos.c into irssi/silc/core/ to return
1181 various stuff for various signal for the statusbar etc. updating.
1182 Now Irssi SILC client prints channel user modes etc. on the
1185 * The user mode (like server/router operator changes) is now shown
1186 on the Irssi SILC client's statusbar. The affected files are
1187 irssi/src/silc/core/client_ops.c, silc-expandos.c.
1189 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1191 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
1192 to SILC_SCHEDULE_[UN]LOCK macros.
1194 * Added more error printing to logs in server code. Affected
1195 files silcd/server.c and silcd/protocol.c.
1197 * Fixed -S option parsing in Irssi SILC Client. Affected file
1198 irssi/src/silc/core/silc-core.c.
1200 * Added silc_buffer_alloc_size function. Affected file is

1225 * Changed all integer type names:
1226 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
1227 to avoid collisions with other libraries using same type names
1230 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1232 * Added `prefer_ipv6' argument to the functions
1233 silc_net_gethostbyname[_async]. If it is TRUE it will return
1234 IPv6 address over IPv4. If FALSE IPv4 address is returned
1235 even if IPv6 address was found. Affected files
1236 lib/silcutil/silcnet.[ch].
1238 * Added support silc_net_create_connection[_async] to fallback
1239 to IPv4 address if IPv6 address could not be used (like if
1240 it doesn't work on a specific system). Affected file in
1241 lib/silcutil/unix/silcunixnet.c.
1243 Sat Feb 23 15:20:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1246 of the max tasks handling capabilities of the scheduler.
1247 Affected files lib/silcutil/silcschedule.[ch].
1249 Wed Feb 20 20:41:01 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1251 * Added automatic extern "C" { ... } for C++ compilers so the
1252 application does not need to define them. Affected file
1253 includes/silcincludes.h.
1255 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
1256 old name went against naming convention. Applications now
1257 include "silcclient.h" instead of "clientlibincludes.h".
1258 Removed includes/clientlibincludes.h, it is redundant now.
1260 * Renamed includes/version.h to silcversion.h.
1262 * Added really preliminary support for OS/2 into the util
1263 library. Only thread & mutex API is implemented, others
1264 are still to be implemented. Created the lib/silcutil/os2/
1265 directory. Created also file includes/silcos2.h.
1267 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1272 includes/silcbeos.h.
1274 Mon Feb 18 15:49:22 EET 2002 Timo Sirainen <tss@iki.fi>
1276 * Added proper initializations to silc's irssi code, so it's
1277 now possible to load it as module. Affected files
1278 irssi/src/silc/core/silc-core.c,
1279 fe-common/silc/fe-common-silc-core.[ch] and fe-text/silc.c

1298 * Added `user_count' to the SilcChannelEntry which now tells the
1299 number of users on the channel. The user count is now saved
1300 in normal server of global channels as well. Affected files
1301 silcd/server.c, idlist.h, packet_receive.c and command.c.
1303 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
1304 include file utility functions.
1306 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
1307 instead of calling directly OS routines.
1309 * Fixed NICK change printing in Irssi SILC Client. Fixed
1310 KICKED notify printing in Irssi SILC Client. Affected file
1311 irssi/src/silc/core/client_ops.c.
1313 * Fixed a NICK change bug in client library, to not recreate the
1314 client_entry->channels hash table everytime nick is changed.
1315 Affected file lib/silcclient/client.c.
1317 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1319 * ROBOdoc documented the lib/silcske/silcske.h, and improved
1320 the SKE interface a bit.
1322 * Fixed padding problem in PKCS#1. The padding was not actually
1323 random since the random number generator was used incorrectly.
1324 This security bug affects only when encrypting with PKCS#1, and
1325 it is not currently used at all in SILC. SILC only use signing
1326 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
1328 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1340 key_exchange_timeout, conn_auth_timeout, connections_max,
1343 Implemented all the new config settings handling in the server.
1345 Optimized the use of SKE Mutual flag usage. Use it only
1346 if connection authentication protocol is not based in public
1349 Renamed all SilcServerConfigSection* to SilcServerConfig*
1350 to have a bit shorter names.
1352 Affected files silcd/serverconfig.[ch], server.[ch], and

1377 section structs, now identifying the param directly.
1379 Added CONFIG_FREE_AUTH macro in config file parsing.
1381 Affected files are silcd/serverconfig.[ch].
1383 Fri Feb 15 12:24:08 EET 2002 Timo Sirainen <tss@iki.fi>
1385 * Fixed command line parameter handling. All SILC initialization
1386 is now done in silc_core_init() which also fixes autoconnecting
1389 Affected files irssi/src/silc/core/silc-core.c,
1390 irssi/src/fe-text/silc.c.
1392 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1394 * Added new configuration options and blocks:
1395 keepalive_secs, reconnect_count, reconnect_interval,
1396 reconnect_interval_max, reconnect_keep_trying and
1397 require_reverser_lookup. Added ConnectionParam block, and
1398 implemented the connection parameters when connecting as
1399 initiator and when accepting connections as responder.
1401 Added CONFIG_IS_DOUBLE macro in config file parsing, to check
1402 whether given configuration value has been given already.
1404 Affected files silcd/serverconfig.[c], server.[c].
1406 * Splitted the doc/example_silcd.conf.in. Separated the crypto
1407 algorithm parts and created new file silcalgs.conf, that
1408 is now included from the example_silcd.conf.in.
1410 * Optimized the silc_server_connect_to_router_second to take
1411 the connection configuration object from the SilcServerConnection
1412 object instead of finding it during the connecting phase.
1413 Added the configuration object to SilcServerConnection struct.
1414 Affected files silcd/server_internal.h, server.c.
1416 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1418 * Add the client on channel after it was resolved at the
1419 channel message receiving, and it was not already on the
1420 channel. Affected file lib/silcclient/client_channel.c.
1422 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1424 * Fixed the public key authentication to allocate always the
1425 destination signature buffer instead of using static buffer.
1426 Affected file silcd/protocol.c.
1428 Wed Feb 13 20:51:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1437 config file, allowing both public key and passphrase based
1438 authentication to be set at the same time.
1440 Added `prefer_passphrase_auth' setting in config file which
1441 can be used to set to prefer passwd auth if both passwd and
1442 public key is set. If not set, public key is preferred.
1443 This has effect only when being initiator (responder will try
1446 Added support for authentication with passphrase and public key
1447 at the same time. The passphrase is tried first always since
1448 it is faster to check.
1450 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
1452 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

1490 * Fixed CUMODE_CHANGE notify handling to change the mode of
1491 correct client. Affected file lib/silcclient/client_notify.c.
1493 * Make silc_rng_alloc fail if it cannot allocate the sha1
1494 hash algorithm. Affected file lib/silccrypt/silcrng.c.
1496 Sun Feb 3 17:20:52 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1498 * Fixed the file transfer's key agreement payload to include
1499 zero port also if the hostname is NULL because it could not
1502 Call file transfer monitor callback now also if error occurs
1503 during key agreement protocol.
1505 Changed the silc_client_file_send interface to return the
1506 SilcClientFileError instead of session id. The session ID
1507 is returned into pointer provided as argument.
1509 Check that the file exists locally before sending the
1510 file transfer request at all.
1512 Affected file lib/silcclient/client_ftp.c, silcapi.h.
1514 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer
1515 error than can occur while key agreement protocol. Affected
1516 file lib/silcclient/silcapi.h.
1518 * Fixed the event_mode CMODE handler to not crash when mode
1519 is changed and +k mode is set in the channel. Affected file
1520 irssi/src/silc/core/silc-channels.c.
1522 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
1523 SILC_LOG_WARNING to give out Warning and not Error. Affected
1524 file lib/silcutil/silclog.c.
1526 * Fixed the channel message payload decryption in the function
1527 silc_channel_message_payload_decrypt to not modify the original
1528 buffer before it is verified that the message decrypted
1529 correctly. Otherwise, next time it is called with correct
1530 channel key it won't encrypt since the payload is corrupted.
1531 Affected file lib/silccore/silcchannel.c.
1533 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1546 the table with foreach callback. The current entry may
1547 become invalid in the callback but it was referenced after
1548 the callback returned.
1550 Do not allow auto rehashing of hash table during the
1551 silc_hash_table_foreach operation, for same reasons as it is
1552 not allowed for SilcHashTableList. Affected files are
1553 lib/silcutil/silchashtable.[ch].
1555 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1557 * Defined DLLAPI into silcincludes.h and silcwin32.h for
1558 Win32 DLL. extern's in header files are now declared with
1561 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1563 * Fixed private message handling. It used some old code that
1564 caused the client to crash. Affecte file is
1565 lib/silcclient/client_prvmsg.c.
1567 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1569 * Added function silc_client_add_channel,
1570 silc_client_replace_channel_id, and removed functions
1571 silc_client_new_channel_id and silc_idlist_get_channel_by_id
1572 from client library.
1574 * Added cross reference of the joined channels to the
1575 SilcClientEntry, and changed the SilcChannelEntry's
1576 users list to SilcHashTable. The affected files are
1577 lib/silcclient/idlist.[ch].
1579 * Fixed a bug in hash table tarversing. While the hash table
1580 is traversed with SilcHashTableList the table must not be
1581 rehashed. It is now guaranteed that auto rehashable tables
1582 are not rehashed while tarversing the list. Also defined that
1583 silc_hash_table_rehash must not be called while tarversing
1584 the table. Added function silc_hash_table_list_reset that must
1585 be called after the tarversing is over. The affected files are
1586 lib/silcutil/silchashtable.[ch].
1588 * Changed all hash table traversing to call the new
1589 silc_hash_table_list_reset in server and in client library.
1591 * Added function silc_client_on_channel to return the
1592 SilcChannelUser entry if the specified client entry is joined
1593 on the specified channel. This is exported to application as
1594 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
1596 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1598 * Fixed founder regaining problem with JOIN command on normal
1599 server. The notify for mode change must be sent always and
1600 not only if !cmd->pending. Affected file silcd/command.c.
1602 * Fixed the WHOWAS command's reply sending to support the
1603 lists correctly. Affected file silcd/command.c.
1605 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1607 * When sending JOIN command to router for processing the
1608 sender's old command identifier was not saved back to the
1609 sender's command context, fixed now. The affected file is
1612 * Create the key in JOIN command of the router did not return
1613 the channel key, added check for this. Affected file is
1616 * Fixed a channel ID update bug in JOIN command reply. Do
1617 not directly upgrade the ID but call the function
1618 silc_idlist_replace_channel_id if the ID was changed.
1619 Affected file silcd/command_reply.c.
1621 * Fixed memory leaks from command calling if it would fail.
1622 Affected file silcd/command.c.
1624 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1626 * Applied patches from cras:
1628 Memory leak fixes around libaries, irssi window resize fix,
1629 new silclist.h and silcdlist.h, all extern inline changed to
1632 * Removed dotconf from lib/dotconf, not needed anymore.
1634 * Removed TRQ from lib/trq, not needed anymore.
1636 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
1637 with server connections. Later this will be configurable
1638 in config file after new config file is done. Affected file
1641 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1643 * Fixed a crash in server related to channel announcements.
1644 Affected file silcd/server.c.
1646 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1648 * Fixed memory leaks in silc_server_create_new_channel*
1649 functions. Affected file silcd/server.c.
1651 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
1652 which ID was changed. This way the router will send the
1653 user list for the channel again, and server won't be in
1654 desync in some rare circumstances. Affected file is
1655 silcd/packet_receive.c.
1657 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1659 * Check for NULL socket pointer in the function
1660 silc_server_packet_send_to_channel_real. Affected file
1661 silcd/packet_send.c.
1663 * Fixed the BAN notify handling to correctly remove ban
1664 list. Affected file silcd/packet_receive.c.
1666 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1668 * Fixed some header addition to Toolkit distribution in
1669 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
1671 * Added lib/silcclient/client_ops_example.h as an template
1672 file for application programmers to quickly start using
1673 the SilcClientOperation functions in their application.
1674 Updated the lib/silcclient/README as well to tell about this
1675 nice file made available.
1677 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1679 * Call silc_server_remove_from_channels when removing client
1680 entry when NO_SUCH_CLIENT_ID was received. Affected file
1681 is silcd/command_reply.c.
1683 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1685 * Added server & router operator statistics updating. Affected
1686 file silcd/packet_receive.c and silcd/command.c.
1688 * Fixed the SERVER_SIGNOFF notify handling on normal server
1689 not to save the history information for clients. Same was
1690 fixed earlier in remove_clients_by_server function, but not
1691 here. Affected file silcd/packet_receive.c.
1693 * Raised the default connection-retry count from 4 to 7 in
1694 server. Affected file silcd/server.h.
1696 * Cancel any possible reconnect timeouts when we start the
1697 key exchange. Affected file silcd/server.c.
1699 * Do not reconnect on connection failure when SCONNECT was
1700 given. Affected files silcd/server.[ch].
1702 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1704 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
1706 * Fixed the NICK command to always give the unformatted
1707 nickname to the one giving the NICK command. If unformatted
1708 nickname is cached already it will be formatted and the
1709 local entry will always get the unformatted nickname.
1710 Affected file lib/silcclient/idlist.c.
1712 * Fixed some double frees from client library commands.
1713 Affected file is lib/silcclient/command.c.
1715 * Fixed CUMODE command in server to assure that no one can
1716 change founder's mode than the founder itself, there was a
1717 little bug. Affected file silcd/command.c.
1719 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1721 * Removed the SilcClientCommandDestructor from the client
1722 libary, it is not needed anymore. Affected files are
1723 lib/silcclient/silcapi.h, command[_reply].[ch],
1724 client_notify, idlist.c.
1726 * Fixed GETKEY command to first resolve client, and then
1727 resolve the server only if the client was not found, instead
1728 of resolving both at the same time. Affected file is
1729 lib/silcclient/command.c.
1731 * Added silc_client_start_key_exchange_cb and lookup the
1732 remote hostname and IP address before starting the key
1733 exchange with server. The affected file is
1734 lib/silcclient/client.c.
1736 * The server's public key is now saved using the IP address
1737 of the server and not the servername for the filename.
1738 The hostname public key filename is checked as an fall back
1739 method if the IP address based filename is not found.
1741 Fixed the GETKEY command to save the fetched server key
1742 in correct filename.
1744 Print the remote server's hostname now when new key is
1745 received during connection process. Affected file is
1746 irssi/src/silc/core/client_ops.c.
1748 * Return always our own public key to the client if it asks
1749 for it with GETKEY command. Affected file silcd/command.c.
1751 * Removed the use_auto_addr variable from default config
1752 file since it was in wrong section. Affected file is
1755 * Fixed TOPIC_CHANGE notification to not route it when it
1756 was sent using silc_server_send_notify_to_channel function.
1757 Affected file silcd/command.c.
1759 * Fixed silc_server_send_notify_kicked to send the kicker's
1760 Client ID also, it was missing. Affected files are
1761 silcd/command.c, silcd/packet_send.[ch].
1763 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1765 * Do not save client history information in SERVER_SIGNOFF.
1766 Fixes the bug in normal server that it does not detect
1767 the client becoming valid after the server becomes back
1768 online. Affected file silcd/server_util.c.
1770 * Added `sock_error' field into the SilcSocketConnection
1771 context. When error occurs during socket operation (read
1772 or write) the error is saved. Added also new function
1773 silc_socket_get_error to return human readable socket error
1774 message. Affected files are lib/silcutil/silcsockconn.[ch],
1775 lib/silcutil/unix/silcunixsockconn.c, and
1776 lib/silcutil/win32/silcwin32sockconn.c.
1778 * The server now prints the socket error message in the
1779 signoff for client. Affected file silcd/server.c.
1781 * Fixed the `created' channel information sending from router
1782 to server in JOIN command. Checks now whether the channel
1783 really was created or not and set it according that.
1785 Fixed the JOIN command to use the client entry's current
1786 ID during the joining procedure instead of the one it sent
1787 in the command (it is checked though), since it can change
1788 between the packet processing and command processing, and
1789 would just case unnecessary pain in the client end. Affected
1790 file silcd/command.c.
1792 * Fixed a channel key payload sending to use correct channel
1793 ID when the server was forced to change the channel's ID by
1794 router. Router sent the key payload with the old Channel ID.
1795 Affected file silcd/packet_receive.c.
1797 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1799 * Call silc_server_save_channel_key only if the key payload
1800 was provided in the JOIN command's command reply. Affected
1801 file silcd/command_reply.c.
1803 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1805 * Fixed silc_mp_sizeinbase to return the value correctly with
1806 MPI. Affected file lib/silcmath/mp_mpi.c.
1808 * Fixed the stop_server signal to correctly stop the scheduler
1809 and gracefully stop the server when SIGTERM or SIGINT signals
1810 are received. Affected file silcd/silcd.c.
1812 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1814 * Simple handling of TERM and HUP signals. Also added some log
1815 flushing call around. Affected file is
1818 * Fixed small bugs in silclog.c. Now buffering output will take
1819 effect after 10 seconds since startup: This will ensure that
1820 no important startup messages are lost. Also output redirection
1821 will preserve original format ([Date] [Type] message).
1822 Affected file is lib/silcutil/silclog.c.
1824 * Added two options to the config file, in the logging section:
1825 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1826 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1828 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1830 * Do not print the warning about log files not being initialized
1831 more than once to avoid excess logging. Affected file is
1832 lib/silcutil/silclog.c.
1834 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1835 the SIM copying in make install in Makefile.am.pre.
1837 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1839 * Rewritten silclog APIs. Globally interesting changes follows:
1840 silc_log_set_files() changed to silc_log_set_file().
1841 silc_log_set_callbacks() changed to silc_log_set_callback().
1842 ROBOdoc documented silclog header file.
1843 SilcLogCb now returns bool to wether inihibit the default
1844 handler or not (to keep the old behaviour return always TRUE).
1845 The new APIs should also fix the problem of the
1846 silcd_error.log file that was written in the current directory.
1849 Log files streams will remain opened after silc_log_set_file()
1850 call, means less CPU usage notably on high traffic servers.
1851 File streams are now full buffered, and flushed to the disk
1852 every 5 minutes, lesses HD activity and CPU usage.
1853 Messages can be redirected, allowing admins to configure
1854 one single logfile for all server messages.
1855 the silc_log_quick global variable to activate fast-logging.
1856 Affected files lib/silcutil/silclog.[ch]
1858 * Changed some code to conform new silclog APIs. Affected
1859 files are doc/example_silcd.conf.in, silcd/server.c
1860 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1863 * Fixed a memory leak that could occur in some situations.
1864 Affected file silcd/serverconfig.c.
1866 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1868 * Added the silc_client_del_client to remove the client from
1869 all channels as well. Affected file lib/silcclient/idlist.c.
1871 * Fixed the client library to correctly remove the client
1872 from all channels when the client entry is being destroyed.
1873 Affected file lib/silcclient/client_notify.c, command.c.
1875 * Added auto-nicking support to the client library. If the
1876 applicatio now sets client->nickname it will be sent to the
1877 server after connecting by the library. This way for example
1878 SILCNICK (or IRCNICK) environment variables will have effect
1879 and always change the nickname automatically to whatever
1880 it is wanted. Affected file lib/silcclient/client.[ch].
1882 * Renamed silc_server_command_bad_chars to the
1883 silc_server_name_bad_chars and moved it to the
1884 silcd/server_util.[ch]. Added also new function
1885 silc_server_name_modify_bad to return nickname that
1886 includes bad characters as new nickname without those
1887 bad characters. This check and modify is now used in
1888 silc_server_new_client when the username is initially set
1889 as nickname, so it must be checked to be valid nickname.
1890 Affected file silcd/packet_receive.c.
1892 * The nickname length is now taken from the packet for real
1893 and not trusted to strlen() since it clearly can return
1894 wrong length for nickname including bad characters. This
1895 also applies to channel names. Affected file silcd/command.c.
1897 * Removed the lib/silcsilm/modules directory. Modules are now
1898 compiled into the lib/silcsim. Fixed the copying of the
1899 modules to follow symbolic links in Makefile.am.pre.
1901 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1903 * Fixed silc_string_regexify list creation. Fixes bugs with
1904 BAN and INVITE commands in server. The affected file is
1905 lib/silcutil/unix/silcunixutil.c.
1907 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1909 * Removed the command destructor entirely from the server's
1910 command and command reply routines. It is not needed, and
1911 its usage was buggy and caused crashes. Affected files are
1912 silcd/command[_reply].[ch].
1914 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1916 * Cancel protocol and NULL sock->protocol if timeout
1917 occurred during protocol. Affected file silcd/server.c.
1919 * Cancel protocol timeouts always before calling the final
1920 callback, to assure that after final callback is called
1921 no other state will be called for the protocol anymore.
1922 Affected file silcd/protocol.c.
1924 * Print error log if incoming connection configuration could
1925 not be found. Affected file silcd/server.c.
1927 * Fixed JOIN command to correctly save the founder mode
1928 to the client on normal SILC server, when the channel
1929 was created by the router. Affected file silcd/command.c.
1931 * Fixed LIST command (hopefully) to send correct reply
1932 packets. Affected file silcd/command.c.
1934 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1936 * The silc_packet_receive_process now returns FALSE if the
1937 read data was invalid packet, and TRUE if it was ok.
1939 The server now checks that if unauthenticated connection
1940 sends data and its processing fails the server will close
1941 the connection since it could be a malicious flooder.
1943 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1945 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1947 * Make sure the warning about error opening a log file is
1948 printed only once and not everytime it fails (produces
1949 too much useless log). Affected file lib/silcutil/silclog.c.
1951 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1953 * Made the silc_server_daemonise() function more readable.
1954 Affected file silcd/server.c.
1956 * Pid file is now optional, the user may comment it out from
1957 the config file. Removed define SILC_SERVER_PID_FILE, we
1958 don't need a default any longer. Affected file
1959 configure.in.pre, lib/Makefile.am.pre.
1961 * Make some use of the pid file. The server now dies at startup
1962 if it detects a valid pid file on his path. The server would
1963 die anyway in this circumstance, because of the bind() failure.
1964 Affected file silcd/silcd.c.
1966 * No longer compiling lib/dotconf.
1968 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1970 * Fixed JOIN command parsing not to crash. Affected file
1971 lib/silcclient/command.c.
1973 * Fied the NICK_CHANGE notify to add the new client entry
1974 even it is resolved. This removes an <[unknown]> nick
1975 thingy bug in the client. Affected file is
1976 lib/silcclient/client_notify.c.
1978 * Do not try to allocate 0 bytes (efence does not like it)
1979 in lib/silccore/silccomand.c when encoding payload.
1981 * Do not take IRCNICK as nickname in Irssi SILC client since
1982 it is not possible to set nickname before hand connecting
1983 the server (TODO has an entry about adding auto-nicking
1986 * Changed the silc_server_command_pending to check whether
1987 there already exists an pending entry with the specified
1988 command, command identifier and pending callback. This is
1989 to fix IDENTIFY and WHOIS related crashes that may register
1990 multiple pending commands with same identifier. Affected
1991 file silcd/command.c.
1993 * Fixed the server to reconnect to the router even if it
1994 was already reconnecting and EOF was received. This to
1995 fix a possibility that the server wouldn't ever try to
1996 auto-reconnect to the router. Affected file silcd/server.c.
1998 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2000 * Fixed the server's password authentication to use the
2001 length of the locally saved password, and not the one
2002 sent in the packet. Affected file silcd/protocol.c.
2004 * Fixed same password authentication problem in the
2005 Authentication Payload handling routines in
2006 lib/silccore/silcauth.c.
2008 * Yet another password authentication problem fixed with
2009 channel password handling in silcd/command.c.
2011 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2013 * If first character of string in silc_parse_userfqdn is '@'
2014 then do not parse it. Affected file is
2015 lib/silcutil/silcutil.c.
2017 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2019 * Fixed minor bug in IDENTIFY command reply sending, which
2020 caused various weird problems during JOIN when it was
2021 resolving names for users. Affected file silcd/command.c.
2023 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2025 * Fixed the IDENTIFY command reply sending to chech better valid
2026 clients. It was possible to send incomplete list of replies.
2027 Affected file silcd/command.c.
2029 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2031 * Added silc_client_command[s]_[un]register functions now to
2032 dynamically register the commands in client library. Removed
2033 the static table of commands. This allows the client library
2034 to call commands without causing the application to know about
2035 what commands library has called.
2037 Removed the INFO command reply kludge to detect when the command
2038 was called by library. Now library use its own command reply
2039 function for INFO command.
2041 Added function silc_client_command_call to call a command.
2042 Application can use it to call command, not access the structure
2045 Now all commands that are sent by the client library (not
2046 explicitly sent by application) use own command reply functions.
2048 Affected files around lib/silcclient/ and in
2049 irssi/src/silc/core/.
2051 * Fixed the WHOIS command reply sending to chech better valid
2052 clients. It was possible to send incomplete list of replies.
2054 Fixed the WHOIS and IDENTIFY to send the request to router
2055 if normal server did not do it and did not find any results.
2057 Affected file silcd/command.c.
2059 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2061 * Moved the internal data from SilcClient context into its
2062 own file, not accesible to application. Affected files
2063 lib/silcclient/client.h and lib/silcclient/client_internal.h,
2064 and other files in client library.
2066 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2068 * Added doc/examples installation target in Makefile.am.pre.
2071 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2073 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
2074 commands the found client entry will be removed from the
2075 cache, after notifying application about the error. Affected
2076 file lib/silcclient/command_reply.c.
2078 * Changed the /MSG to check for exact nickname user gave, and
2079 not let `nick' match `nick@host' if it is only one found. Now,
2080 user must type the exact nickname (like nick@host2) even if
2081 there are no more than one same nicks found. This is to avoid
2082 a possibility of sending nickname to wrong nickname since
2083 `nick' could match `nick@host'. Affected file is
2084 irssi/src/core/silc-servers.c.
2086 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2088 * Do not print "you are now server operator" or similar when
2089 giving /away command. Affected files are
2090 irssi/src/silc/core/client_ops.c, silc-servers.h.
2092 * Made the silc_server_command_pending_error_check to send
2093 the same command reply payload it received back to the
2094 original sender of the command. This way all arguments
2095 that was received by the server will be received by the
2096 client too. Affected file silcd/command.c.
2098 * Added the silc_idcache_add to return the created cache entry
2099 to a pointer. Affected file lib/silccore/silcidcache.[ch].
2101 * Add global clients to expire if they are not on any channel.
2102 This is because normal server will never know if they signoff
2103 if they are not on any channel. The cache expiry will take
2104 case of these entries. This is done by normal servers only.
2105 The affected files are silcd/command_reply.c,
2106 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
2108 * If server receives invalid ID notification for WHOIS or
2109 IDENTIFY and the ID exists in the lists, it is removed.
2110 Affected file silcd/command_reply.c.
2112 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
2113 in client then client entry that it matches is searched and
2114 the nickname is printed on the screen for user. Affected
2115 file irssi/src/silc/core/client_ops.c.
2117 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2119 * Use cache entry expire time in the LIST command reply to
2120 purge old entries from the cache after the LIST command
2121 reply has been received. This way we don't have non-existent
2122 entries in the cache for too long. Affected file is
2123 silcd/command_reply.c.
2125 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2127 * If we are normal server, and we've not resolved client info
2128 in WHOIS or IDENTIFY from router, and it is global client,
2129 we'll check whether it is on some channel. If it is not
2130 then we cannot be sure about its validity and will resolve it
2131 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
2132 file silcd/command.c.
2134 * Search channel by name (if possible) rather than by ID
2135 in IDENTIFY command's command reply. Affected file is
2136 silcd/command_reply.c.
2138 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2140 * Distribute to the channel passphrase in CMODE_CHANGE notify.
2141 Updated specs and implemented it. Affected file silcd/command.c,
2142 silcd/packet_send.c and silcd/packet_receive.c.
2144 * Implemented the <founder auth> payload handling in the JOIN
2145 command. If provided all conditions for channel joining
2146 except requirement to provide correct passphrase can be
2147 overrided by the channel founder. Updated the protocol specs.
2148 Affected file silcd/command.c.
2150 Added support for founder auth in JOIN command in client
2151 library. Fixed the parsing of the JOIN command now to support
2152 all options as they should be. The affected file is
2153 lib/silcclient/command.c.
2155 * Optimized the WHOIS and IDENTIFY commands to send the request
2156 to router only if it includes nicknames or other names. If
2157 they include only IDs then check the local cache first before
2158 routing. Affected file is silcd/command.c.
2160 * Added channels topic announcements. Affected file is
2161 silcd/packet_receive.c and silcd/server.c.
2163 * Fixed the silc_server_send_notify_topic_set to really destine
2164 the packet to channel. Affected file silcd/packet_send.c.
2166 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
2167 library. Affected file lib/silcclient/client_notify.c.
2169 * Added UMODE announcements. Affected file silcd/server.c.
2171 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2173 * Memory leak fixes in:
2175 lib/silcutil/silcsockconn.c
2176 lib/silcske/silcske.c
2177 lib/silcske/groups.c
2179 lib/silccrypt/silcpkcs.c
2180 lib/silccore/silccommand.c
2181 lib/silccore/silcidcache.c
2186 * ROBOdoc documented the lib/silcske/groups.h file and a
2187 bit changed the interface for better.
2189 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2191 * Update the client entry context in the ID cache after
2192 nick change. Affected file lib/silcclient/command.c.
2193 Fixes the CUMODE command when regaining founder privileges,
2194 and a little WHOIS problem.
2196 * Fixed silc_net_gethostbyname to correctly call the
2197 inet_ntop. Affected file lib/silcutil/silcnet.c.
2199 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2201 * Added IPv6 support checking to the configure.in.pre, added
2202 also --enable-ipv6 option to override the check. Affected
2203 file configure.in.pre.
2205 * The silc_thread_create now calls the start function
2206 directly if threads support is not compiled in. Removes
2207 ugly #ifdef's from generic code. Affected files are
2208 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
2210 * Added silc_net_gethostby[name/addr]_async to asynchronously
2211 resolve. Affected files are lib/silcutil/silcnet.[ch].
2213 * Added support for rendering IPv6 based server, client and
2214 channel IDs. Affected file lib/silcutil/silcutil.c.
2216 * Added support for creating IPv6 based server IDs. Affected
2217 file is silcd/serverid.c.
2219 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2221 * Added silc_net_gethostby[addr/name] into the
2222 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
2223 routines. Added silc_net_is_ip[4/6]. Affected file is
2224 lib/silcutil/unix/silcunixnet.c. All routines that take
2225 address as argument now supports both IPv4 and IPv6 addresses.
2227 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2229 * Fixed LIST command reply sending in server. Affected file
2232 * Server now sends the kicker's client ID in the KICK notify
2233 to the kicked client. Affected file silcd/command.c.
2235 * The client library now parses the kickers client ID and
2236 UI displays it. Affected files lib/silcclient/client_notify.c
2237 and irssi/src/silc/core/silc-channels.c, module-formats.c.
2239 * Made all payload parsing function prototypes consistent.
2240 They all take now const unsigned char * and uint32 pair as
2241 the payload data instead of SilcBuffer. Changes all around
2242 the source tree. Other unsigned char* -> const unsigned char*
2243 changes around the tree as well.
2245 * Optimized SFTP client and server packet sending not to
2246 allocate new buffer for each packet but to recycle the
2247 first allocated buffer. Affected files are
2248 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
2250 * Optimized the SFTP client to use SilcList instead of
2251 SilcDList for requests, because it is faster. Affected file
2252 is lib/silcsftp/sftp_client.c.
2254 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
2255 into lib/silccore/silcid.[ch].
2257 Renamed silcpayload.[ch] into silcargument.[ch].
2259 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2261 * If client entry is deleted with active key agreement
2262 session, abort the session.
2264 The silc_client_abort_key_agreement now calls the completion
2265 callback with new SILC_KEY_AGREEMENT_ABORTED status.
2267 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
2270 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2272 * Don't use __restrict in older GCC's. Affected file is
2273 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
2275 * silc_net_localhost now attempts to reverse lookup the
2276 IP/hostname. Affected file lib/silcutil/silcnet.c.
2278 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
2279 command. It can be used to gain founder privileges at
2280 the same time when joining the channel.
2282 Defined that the SILC_NOTIFY_TYPE_KICKED send the
2283 kicker's client ID as well. Updated protocol specs.
2285 Defined that the server must send SILC_COMMAND_IDENTIFY
2286 command reply with error status to client who sent
2287 private message with invalid client ID.
2289 Updated the protocol specification.
2291 * Added silc_server_send_command_reply to send any
2292 command reply. Affected file silcd/packet_send.[ch].
2294 * Added silc_id_payload_encode_data to encode ID payload
2295 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
2297 * The server now send IDENTIFY command reply with error
2298 status if client ID in private message is invalid. Affected
2299 file silcd/packet_receive.c.
2301 * Save the server key file with server's IP address in
2302 the filename instead of hostname. The affected file is
2303 irssi/src/silc/core/client_ops.c.
2305 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2307 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
2310 * Added libtool support for compiling shared objects in
2311 lib/silcsim. Affected file configure.in.pre and
2312 lib/silcsim/Makefile.am. Original patch by cras.
2314 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2316 * Pid file configuration, and server's config file fixes
2317 patch by toma. Updated CREDITS file.
2319 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2321 * Fixed silc_client_channel_message to not try to decrypt
2322 the message twice if it resolved the destination client
2323 information. This could cause of dropping one channel
2324 message. Affected file lib/silcclient/client_channel.c.
2326 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2328 * Added silc_client_run_one into lib/silcclient/silcapi.h and
2329 lib/silcclient/client.c. This function is used when the SILC
2330 Client is run under some other scheduler, or event loop or
2331 main loop. On GUI applications, for example this may be
2332 desired to used to run the client under the GUI application's
2333 main loop. Typically the GUI application would register an
2334 idle task that calls this function multiple times in a second
2335 to quickly process the SILC specific data.
2337 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2339 * Fixed silc_server_drop() for dropping the supplementary
2340 groups as well, this could cause a security hole on some
2343 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2345 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
2348 * Write PID file after dropping privileges. Added -F option
2349 to run server on foreground. A patch by debolaz.
2350 Affected files silcd/server.c, silcd/silcd.c.
2352 * Fixed MOTD to return the MOTD file server name. Affected
2353 file silcd/command.c.
2355 * Added INFO command reply handling to the Irssi SILC Client.
2356 Affected file irssi/src/silc/core/client_ops.c.
2358 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2360 * Fixed the silc_idcache_list_* routines to really support
2361 the dynamic list. Fixes a crash. Affected file is
2362 lib/silccore/silcidcache.c.
2364 * Fixed the LIST command reply to really call LIST command's
2365 pending callbacks. Affected file silcd/command_reply.c.
2367 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2369 * Update conn->local_entry->nickname after giving NICK
2370 command. Affected file lib/silcclient/command.c.
2372 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
2374 * Added the [pid] option to the silcd configuration file
2376 Affected files: serverconfig.[ch] and silcd.c
2378 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2380 * Save fingerprint in WHOIS command reply in server.
2381 Affected file silcd/command_reply.c.
2383 * Fixed NICK commands pending callback registration.
2384 Affected file lib/silcclient/command.c.
2386 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2388 * Use ++server->cmd_ident when sending commands in server,
2389 instead of random number. Affected file silcd/command.c.
2391 * Fixed GETKEY command reply to call actually GETKEY pending
2392 command callbacks. Affected file silcd/command_reply.c.
2394 * A bit stricter check for nicknames. Check for same nickname
2395 in NICK command also. Affected file silcd/command.c.
2397 * Do not call INFO command everytime client ID changes, only
2398 during first connecting. Affected file lib/silcclient/client.c.
2400 * Set the new nickname only after successful command reply for
2401 NICK command is returned by server. Affected file
2402 lib/silcclient/command.c.
2404 * Remove nicknames from nicklist during server_signoff notify.
2405 Should fix /NAMES bit more. The affected file is
2406 irssi/src/silc/core/silc-channels.c.
2408 * Added `fingerprint' field to the SilcIDListData in the
2409 silcd/idlist.h to hold the fingerprint of the client's
2412 Send the fingerprint of the client's public key in WHOIS
2415 Affected files silcd/command.c, and silcd/idlist.[ch].
2417 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
2418 create fingerprint from given data.
2420 * Show the fingerprint of the client's public key in WHOIS.
2421 Affected files irssi/src/module-formats.[ch] and
2422 irssi/src/silc/core/client_ops.c.
2424 * Format the multiple same nicknames also during JOIN and
2425 NICK_CHANGE notifys. Affected file is
2426 lib/silcclient/client_notify.c.
2428 * Do not print error on screen for invalid private message
2429 payload since it can come if someone is sending private
2430 messages with wrong key. Affected file
2431 lib/silccore/silcprivate.c.
2433 * Fixed multiple concurrent /PING crash. Affected file
2434 lib/silcclient/command.c.
2436 * Changed the wrong ID encoding. All IP addresses must be
2437 in MSB first order in encoded format. They were encoded
2438 wrong and was in LSB format. Affected files are
2439 silcd/serverid.c, lib/silcutil/silcutil.c.
2441 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
2443 * Call the `connect' client operation through the scheduler
2444 in case of error. Affected file lib/silcclient/client.c.
2446 * Call the `failure' client operation even if the error
2447 occurred locally during a protocol. Affected file is
2448 lib/silcclient/protocol.c.
2450 * Added support of sending LIST command to router from normal
2451 server. This way normal server can get list of all channels
2452 in the network too. Fixed the channel list sending in the
2453 server too. Affected files are silcd/command.c, and
2454 silcd/command_reply.[ch].
2456 * Added silc_server_update_channels_by_server and
2457 silc_server_remove_channels_by_server. They are used during
2458 disconnection of primary router and in backup router protocol.
2459 Affected file silcd/server_util.[ch], silcd/server.c and
2460 silcd/server_backup.c.
2462 * Fixed channel adding to global list in IDENTIFY command
2463 reply in server. Affected file silcd/command_reply.c.
2465 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2467 * If the incoming packet type is REKEY or REKEY_DONE process
2468 that packet always synchronously. Fixes yet another MAC
2469 failed error on slow (dialup) connections. Affected file
2470 lib/silcclient/client.c and silcd/server.c.
2472 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2474 * Call check_version SKE callback for initiator too. Affected
2475 file lib/silcske/silcske.c.
2477 * Implemented fix for security hole found in the SKE that was
2478 fixed in the specification few days back; the initiator's
2479 public key is now added to the HASH value computation.
2480 Added backwards support for the old way of doing it too, for
2481 old clients and old servers. Affected file is
2482 lib/silcske/silcske.c.
2484 * Enabled mutual authentication by default in SKE. If initiator
2485 is not providing mutual authentication the responder will
2486 force it. This will provide the proof of posession of the
2487 private key for responder. The affected files are
2488 lib/silcclient/protocol.c and silcd/protocol.c.
2490 * Do not cache anymore the server's public key during SKE.
2491 We do mutual authentication so the proof of posession of
2492 private key is done, and if the server is authenticated in
2493 conn auth protocol with public key we must have the public
2494 key already. Affected file silcd/protocol.c.
2496 * Added new global debug variable: silc_debug_hexdump. If
2497 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
2498 file lib/silcutil/silclog.[ch].
2500 * Fixed compilation warning due to char * -> const char *.
2501 Affected files lib/silcutil/silcnet.h, and
2502 lib/silccore/silcauth.[ch].
2504 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2506 * Fixed CMODE command when new channel key was created. If
2507 the creation failed the old key was removed. Next time giving
2508 same command would crash the server since the old key was
2509 freed already. Affected file silcd/command.c.
2511 * Fixed the silc_server_announce_get_channels to not crash
2512 on reconnect. Affected file silcd/server.c.
2514 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2516 * Added silc_log_set_debug_string function to set a regex
2517 string to match for debug output. Only the function names,
2518 or filenames matching the given debug string is actually
2519 printed. This way it is possible to filter out those debug
2520 strings that user is not interested in.
2522 Fixed a bug in silc_string_regexify.
2524 Affected files lib/silcutil/silclog.[ch], and
2525 lib/silcutil/unix/silcunixutil.c.
2527 * Changed the -d options in both server and Irssi SILC client
2528 to take the debug string as argument. Affected files
2529 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
2531 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2533 * Added silc_hash_babbleprint to create a Bubble Babble
2534 Encoded fingerprint. The encoding is developed by Antti
2535 Huima (draft-huima-babble-01.txt), and it creates human
2536 readable strings out of binary data. Affected file
2537 lib/silccrypt/silchash.[ch].
2539 * Print the babble print now in addition of fingerprint as well
2540 in Irssi SILC client. Affected files are
2541 irssi/src/fe-common/silc/module-formats.[ch],
2542 irssi/src/fe-common/silc/core/client_ops.c.
2544 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2546 * Fixed a security problem found in SKE. The initiator's
2547 public key too is now added to the HASH hash value creation
2548 which is signed by the responder to create the SIGN value.
2549 This will prevent anyone in the middle to lie to the responder
2550 about the initiator's public key. If this is done now, the
2551 man in the middle will get caught. Updated the protocol
2554 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2556 * Better installation directory handling. Configure module
2557 paths and other paths automatically to example_silc* files
2558 in doc/. A patch by toma.
2560 * Fixed compiler warning from MPI library, and from SILC RNG.
2563 * Added SILC_SERVER_PID_FILE to define the pid file for server.
2564 It can be configured with ./configure. A patch by toma.
2566 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2568 * Find correct make to use in prepare-clean. A patch by
2569 toma. Affected file prepare-clean.
2571 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
2573 * Added irssi variables use_auto_addr, auto_bind_ip,
2574 auto_bind_port and auto_public_ip.
2576 * Changed the interface for silc_client_send_key_agreement
2577 in lib/silcclient/silcapi.h
2581 irssi/src/silc/core/silc-core.c
2583 lib/silcclient/silcapi.h
2584 irssi/src/silc/core/silc-channels.c
2585 lib/silcclient/client_keyagr.c
2588 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2590 * Added silc_pkcs_public_key_compare to compare two
2591 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
2593 * Check that the client who set the founder mode on the
2594 channel is the same client that is giving the founder
2595 mode to itself. It is done by comparing the saved public
2596 key (it is saved even in the authentication is passphrase).
2597 Affected file silcd/command.c.
2599 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2601 * Do not process packet for disconnected socket connection.
2602 Affected file lib/silccore/silcpacket.c.
2604 * Process the DISCONNECT packet through scheduler in the
2605 client library. Affected file lib/silcclient/client.c.
2607 * Fixed the silc_client_packet_parse to not to increase
2608 the packet sequence number if the conn->sock and the
2609 current socket connection is not same. This can happen
2610 for example during key agreement when the conn includes
2611 multiple socket connections (listeners). Affected file
2612 lib/silcclient/client.c.
2614 * The sender of the file transfer request now provides also
2615 the pointer (listener) for the key exchange protocol. If
2616 the listener cannot be created then it sends empty key
2617 agreement and lets the receiver provide the listener.
2619 Added `local_ip' and `local_port' arguments to the
2620 silc_client_file_send. If they are provided they are used,
2621 if not then it will attempt to find local IP address, if
2622 not found or bind fails then the remote client will provide
2625 Affected files are lib/silcclient/client_ftp.c and
2626 lib/silcclient/silcapi.h.
2628 * Extended the FILE SEND command to support defining the

2635 of the client's public key (if the proof of posession of the
2636 corresponding private key is verified by the server).
2637 Updated to the protocol specification.
2639 * Added support of receiving the client's public key's
2640 fingerprint in command reply in client library. Affected
2641 file is lib/silcclient/command_reply.c, and
2642 lib/silcclient/idlist.[ch].

2701 preserve the WHOWAS info for the client. Affected file
2702 silcd/server_util.c.
2704 * Fixed SERVER_SIGNOFF notify handling in the server. The
2705 server is now able to process incoming SERVER_SIGNOFF notify
2706 for a server that it doesn't even know about. It will remove
2707 the clients provided in the notify. Affected file
2708 silcd/packet_receive.c.
2710 * Check for partial packet in data queue after every packet that
2711 was found from the queue. Return and wait for more data if
2712 there is partial data in queue. Affected file is
2713 lib/silccore/silcpacket.c.
2715 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>

2730 irssi/src/fe-common/silc/module-formats.[ch].
2732 * Wrote a help file for FILE command.
2734 * Added silc_rng_global_get_byte_fast to get not-so-secure
2735 random data as fast as possible. Random data is read from
2736 /dev/urandom if available and from the SILC RNG if not
2737 available. It is used in padding generation. Affected file
2738 lib/silccrypt/silcrng.[ch].
2740 * All packets in client library are now processed synchronously.
2741 Optimized packet processing a lot. Affected file
2742 lib/silcclient/client.c.

2753 * Assure that silc_client_notify_by_server_resolve does not
2754 resolve the client information multiple times. If it cannot
2755 be found by the first it cannot be found at all. Affected
2756 file lib/silcclient/client_notify.c.
2758 * Fixed WHOWAS command reply calling. Affected file
2759 lib/silcclient/command_reply.c.
2761 * Removed all references to silc_idlist_get_client from the
2762 Irssi SILC client since that call is internal call used by
2763 the library. The Irssi SILC client will use now client
2764 retrieval functions found in silcapi.h.
2766 * Fixed a bug in resolving nickname info before sending
2767 private message. It used freed memory. Affected file
2768 irssi/src/silc/core/silc-servers.c.
2770 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2772 * Assure my_channels statistics cannot go negative in server.
2773 Affected files silcd/server.c, silcd/server_util.c.

2789 * Added silc_net_localip to return local host's IP address.
2790 Affected file lib/silcutil/silcnet.[ch].
2792 * If key exchange or rekey protocol is active for a connection
2793 parse all packets syncronously since there might be packets
2794 in packet queue that we are not able to process without first
2795 processing packets before them. Affected file silcd/server,
2796 lib/silcclient/client.c.
2798 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2799 whether library should continue processing the packet.
2800 Affected file lib/silccore/silcpacket.h.

2846 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
2847 is incomplete and is being resolved, it won't be resolved
2850 Make sure also that USERS command reply does not resolve
2851 twice information. Affected file is
2852 lib/silcclient/command_reply.c.
2854 Make sure that silc_client_get_clients_by_list does not
2855 resolve twice same information.
2857 * Check for valid client->id in the silc_server_free_client_data.
2858 Affected file silcd/server.c.
2860 * Fixed /GETKEY nick@server not to crash if the server entry
2861 is not found. Affected file lib/silcclient/command.c.
2863 * Fixed the silc_server_check_cmode_rights to check the
2864 requested modes correctly. Affected file silcd/command.c.

2868 * Better checks for non-printable chars in nick added.
2869 Affected file silcd/command.c.
2871 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2873 * Call the silc_server_udpate_servers_by_server in the
2874 primary router that comes back online in the backup resuming
2875 protocol. Otherwise it routes packets wrong. Affected file
2876 silcd/server_util.[ch], silcd/server_backup.c.
2878 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2880 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2881 lib/silcutil/silcbuffmt.[ch].
2883 * Redefined the SILC packet header to include the padding
2884 length. Affected file lib/silccore/silcpacket.[ch].
2886 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2887 length for maximum padding up to 128 bytes). Affected
2888 file lib/silccore/silcpacket.h.
2890 * Removed all backwards support for old 0.5.x MAC thingies.
2891 The SILC packet header change makes it impossible to be
2892 backwards compatible.
2894 * Send the ENDING packet with timeout in the backup resuming
2895 protocol. This is to assure that all routers has connected
2896 to the primary router. Affected file silcd/server_backup.c.
2898 * Changed the RNG to take the first IV from random data. It
2899 used to take it from zero actually. Changed the RNG also
2900 to use /dev/urandom during session. /dev/random is used
2901 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2903 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2905 * Changed the SILC packet header to have the first two bytes
2906 (the packet length) encrypted. Affected files aroung the
2907 code tree, lib/silccore/silcpacket.[ch]. Removed the
2908 SilcPacketCheckDecrypt callback. It is not needed anymore
2909 since the silc_packet_receive_process will determine now
2910 whether the packet is normal or special.
2912 * Implemented the unidirectional MAC keys. Affected files
2913 lib/silcske/silcske.c, silcd/protocol.c and
2914 lib/silcclient/protocol.c.
2916 * Implemented the packet sequence number to the MAC computation.
2917 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
2918 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
2919 lib/silcclient/protocol.c.
2921 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2923 * Allow backup router to announce servers. All servers
2924 announced by backup router are added to the global list
2925 automatically. Update hte server's socket to our primary
2926 router also when backup router announces a server.
2927 Affected file silcd/packet_receive.c.
2929 * Do not update the client->router in the function
2930 silc_server_udpate_clients_by_server if the client is on
2931 global list. We might fail to find any specific server
2932 for locally connected clients and local cell clients. They
2933 should still use the `from' and not `to' as client->router.
2934 This fixes backup router resuming protocol. Affected file
2935 silcd/server_util.c.
2937 * Decrease channel statistics count only if the channel
2938 deletion worked. Affected files are silcd/server.c and
2939 silcd/server_util.c.
2941 * Added silc_server_update_servers_by_server to update origin
2942 of all server entries. Used during backup router protocol.
2943 Affected files silcd/server_util.[ch], silcd/server.c. and
2944 silcd/backup_router.c.
2946 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
2947 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
2948 silc_hmac_get_hash and silc_hmac_get_name. Affected file
2949 lib/silccrypt/silchmac.c.
2951 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2953 * Assure that router cannot reroute the same channel message
2954 to the sender. Affected file silcd/packet_receive.c.
2956 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2958 * Made better checks that the channel message is not sent
2959 to the router it came from. Affected file is
2960 silcd/packet_send.c. Fixed memory leak too.
2962 * Announce informations for incoming router connection, but
2963 only after checking if it is replaced by backup router.
2964 Affected file silcd/packet_receive.c.
2966 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2968 * Fixed the backup resuming protocol to work in multiple
2969 router environment. Affected file silcd/server_backup.c.
2971 * Route packet only to one router in the function
2972 silc_server_packet_send_to_channel. Affected file is
2973 silcd/packet_send.c.
2975 * Fixed silc_server_send_notify_dest to set the broadcast
2976 flag. Fixed the silc_server_send_notify_topic to actually
2977 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2978 Affected file silcd/packet_send.c.
2980 * Changed the SFTP Filesystem interface. Changed the
2981 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2982 the filesystem operation function. The SilcSFTPFilesystem
2983 is now a context that is allocated by all filesystem allocation
2984 functions and it already includes the operations structure
2985 and filesystem specific context. It is given as argument
2986 now to the silc_sftp_server_start. This made the interface
2987 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2988 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2990 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2992 * Changed the backup router adding and getting interfaces
2993 in the server. The router that will be replaced by the
2994 specified backup router is now sent as argument. Affected
2995 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2998 * Added silc_net_addr2bin_ne to return the binary form of
2999 the IP address in network byte order. Affected files
3000 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
3002 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3004 * Check for existing server ID in silc_server_new_server
3005 and in silc_server_connect_to_router_final and remove the
3006 old entry if it exists. Affected file silcd/packet_receive.c,
3009 * Send the channel message always to only one router, either
3010 in upstream or downstream. Affected file is
3011 silcd/packet_send.c.
3013 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3015 * Wrote the definition of the backup resuming protocol to the
3016 protocol specification.
3018 * Removed one redundant channel key generation from normal
3019 server during joining procedure. Removed one redundant
3020 channel key sending from server to router during joining
3021 procedure. Affected file silcd/command.c.
3023 * Made minor bugfixes to the backup router resuming protocol.
3024 Affected file silcd/server_backup.c, server.c.
3026 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3028 * Added --disable-asm configuration option. Affected files
3029 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
3032 * Implemented the backup resuming protocol that is used to
3033 resume the primary router position in the cell after the
3034 primary router comes back online. Affected files
3035 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
3036 and silcd/server_util.[ch].
3038 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3040 * Sleep two (2) seconds after sending QUIT command to server.
3041 Affected file lib/silcclient/command.c.
3043 * Assure that if outgoing data buffer is pending do not force
3044 send any data. Affected file silcd/packet_send.c.
3046 * Assure that if outgoing data buffer is pending do not force
3047 send any data. Affected file lib/silcclient/client.c.
3049 * Implemented the backup router support when the primary router
3050 goes down. The servers and routers can now use the backup
3051 router as new primary router without loosing connectivity.
3053 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3055 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
3056 in the server to indicate disabled entry. All data read
3057 from the connection will be ignored and no data is sent
3058 for entry that is disabled. Affected files are
3059 silcd/idlist.h, silcd/server.c.
3061 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3063 * Created SFTP client and server test programs in the
3064 lib/silcsftp/tests directory.
3066 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3068 * Implemented memory filesystem (virtual filesystem) for
3069 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
3072 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3074 * Implemented the SFTP (SSH File Transfer Protocol) to the
3075 lib/silcsftp. It includes SFTP client and SFTP server
3078 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3080 * Moved lib/silccore/silcprotocol.[ch] to the
3081 lib/silcutil library.
3083 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
3084 take variable argument list pointer as argument. Affected
3085 file lib/silcutil/silcbuffmt.[ch].
3087 * Added silc_buffer_set function that is used to set data
3088 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
3089 Affected file lib/silcutil/silcbuffer.h.
3091 * Changed various routines in the core library to use the new
3092 silc_buffer_set instead of allocating new buffer only for
3095 * Added 64-bit value formatting and unformatting support to the
3096 silc_buffer_[un]format routines. Affected file is
3097 lib/silcutil/silcbuffmt.[ch].
3099 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
3100 to includes/bitmove.h.
3102 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3104 * Fixed channel user mode saving in client library. Affected
3105 file lib/silcclient/command[_reply].c.
3107 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3109 * Defined the file transfer to the SILC Protocol. Added
3110 new packet type SILC_PACKET_FTP and defined File Transfer
3111 Payload. The mandatory file transfer protocol is SFTP
3112 (SSH File Transfer Protocol). Affected file in addition
3113 of the internet draft is lib/silccore/silcpacket.h.
3115 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
3116 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
3117 is used as part of backup router protocol when the primary
3118 router of the cell is back online and wishes to resume
3119 the position as primary router.
3121 * Redefined the MAC generation keys in the protocol. The
3122 same key is not used anymore in both direction. Both
3123 direction will now use different keys for sending and
3124 receiving. This fixes a potential security flaw. This
3125 change causes incompatibilities in the protocol.
3127 * Redefined also the MAC computation from the packet.
3128 An packet sequence number is now added to the MAC
3129 computation. This prevents possible replay attacks against
3130 the protocol. This change too causes incompatibilities
3133 Added `sequence' field to the SilcPacketContext to hold
3134 the current sequence number for the packet.
3136 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3138 * Added `created' field to the SilcIDListData in the file
3139 silcd/idlist.h to indicate the time when the entry was
3142 * Added `created' field to the SilcChannelEntry too. Affected
3143 file silcd/idlist.h.
3145 * Added `creation_time' aguments to all the announcement functions
3146 in the server. If it is provided then only the entries that
3147 was created after the provided time frame are actually
3148 announced. Affected file silcd/server.[ch].
3150 * The protocol says that the Channel ID's IP address must be
3151 based on the router's IP address. Added check for this in
3152 the silc_server_new_channel when processing incoming New Channel
3153 Payload. Affected file silcd/packet_receive.c.
3155 * Print out the correct version with --version in SILC client.
3156 Affected file irssi/src/silc/core/silc-core.c.
3158 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3160 * Fixed WHOWAS command to check for completnes of the client
3161 entry always, not just when the command is coming from client.
3162 Affected file silcd/command.c.
3164 * Added new function silc_server_packet_queue_purge to purge the
3165 outgoing data queue to the network. After the function returns
3166 it is guaranteed that the outgoing packet queue is empty.
3167 Affected file silcd/packet_send.[ch].
3169 * Purge the outgoing packet queue in the rekey protocol's final
3170 callback to assure that all rekey packets go to the network
3171 before quitting the protocol. Affected file silcd/server.c.
3173 * Added silc_client_packet_queue_parse as similar function as
3174 in server to the client library. The affected file is
3175 lib/silcclient/client.c.
3177 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3179 * Splitted silcd/server.c and created silcd/server_util.[ch]
3180 for utility functions.
3182 * Added new socket flag SILC_SF_DISABLED to indicate that the
3183 connection is open but nothing can be sent to or received from
3184 the connection. Affected file lib/silcutil/silsockconn.[ch].
3185 The checking for disabled socket is checked in the low level
3186 silc_socket_write and silc_socket_read functions.
3188 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3190 * Allow only nicknames and channel names that fits into the
3191 7-bit unsigned char ASCII set. Affected file silcd/command.c.
3193 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3195 * When processing JOIN command reply in server check that if
3196 the channel exists in our global list we'll move it the local
3197 list. Affected file silcd/command_reply.c.
3199 * Fixed the check whether client is joined on the channel already
3200 in JOIN command. Affected file lib/silcclient/command.c.
3202 * Fixed the JOIN command reply to check whether the channel
3203 already exists. Affected file lib/silcclient/command_reply.c.
3205 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3207 * Added silc_ske_status_string to map the SKE error numbers
3208 to readable strings. The affected files are
3209 lib/silcske/silcske[_status].[ch].
3211 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3213 * Do not show the private channels on the WHOIS channel list
3214 as it is not allowed by the protocol. The affected file is
3217 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3219 * Assure that the packet length digged from the actual packet
3220 is something sensible in the silc_packet_decrypt_rest_special
3221 in lib/silccrypt/silcpacket.c.
3223 * Free and NULL the allocated pointer in silc_hmac_alloc if
3224 the HMAC allocation fails. The affected file is
3225 lib/silccrypt/silchmac.c.
3227 * Print the selected security properties to the log files in
3228 the server. Affected file silcd/protocol.c.
3230 * Add SKE's reference counter even if calling the completion
3231 callback manually. Otherwise it goes negative, although it
3232 does not cause any problems. The affected file is
3233 lib/silcske/silcske.c.
3235 * Remove the client entry with short timeout after giving the
3236 KILL command. Affected file lib/silcclient/command.c.
3238 * Fixed to send error reply in WHOIS and IDENTIFY commands in
3239 case all found clients are already disconnected (WHOWAS would
3240 found them) in the server. Affected file silcd/command.c.
3242 * Update the last_receive (time of last data received) to be
3243 updated only when received private or channel message so that
3244 the idle time showed in WHOIS makes more sense.
3246 * Added boolean field `valid' in to the SilcClientEntry in the
3247 client library to indicate whether the entry is valid or not.
3248 This fixes the nickname change bug on channel when changing
3249 the nickname to be same than the old (like nick to Nick) the
3250 nickname formatter doesn't set the new nick anymore to Nick@host.
3251 Affected file lib/silcclient/idlist.[ch].
3253 * Now actually fixed the nickname changing on disconnection.
3254 Added new function silc_change_nick to the Irssi SILC Client.
3255 Affected file irssi/src/silc/core/client_ops.c,
3256 irssi/src/silc/core/silc-nicklist.[ch].
3258 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3260 * Check that the public key exists in the GETKEY command before
3261 trying to encode it. Affected file silcd/command.c.
3263 * Print some notifications on received public keys with GETKEY
3264 command in the Irssi SILC Client. Affected files are
3265 irssi/src/fe-common/silc/module-formats.[ch],
3266 irssi/src/silc/core/client_ops.c.
3268 * Use IDENTIFY command to resolve the server information in the
3269 GETKEY command instead of INFO command. Affected file
3270 lib/silcclient/command.c.
3272 * All command reply functions in the client library now calls
3273 the pending command reply callbacks even if an error has
3274 occurred. The server has done this a long time and now it was
3275 time to move the client library to this as well. Now all
3276 errors can be delivered back to the pending command reply
3277 callbacks if necessary. Affected files are
3278 lib/silcclient/command[_reply].[ch].
3280 * Change the nickname on disconnection back to the username
3281 because in reconnect the server will enforce it to it anyway.
3282 Affected file irssi/src/silc/core/silc-servers.c.
3284 * Fixed a config file parsing bug in the Irssi SILC client.
3285 Affected file irssi/src/silc/core/clientconfig.c.
3287 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3289 * When printing the channel mode on JOIN, verify that the
3290 channel key and channel's HMAC are valid. Affected file
3291 irssi/src/silc/core/client_ops.c.
3293 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3295 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
3296 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
3297 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
3299 * Removed channel key rekey task deleting from the function
3300 silc_server_save_channel_key. Affected file silcd/server.c.
3301 Added explicit timeout task context instead that is used to
3302 delete the task if we are registering a new task before the
3303 new task has elapsed.
3305 * When channel key rekey occurs the client library now saves
3306 the old channel key for a short period of time (10 seconds) and
3307 is able to use it in case some is still sending channel
3308 messages encrypted with the old key after the rekey. Affected
3309 file lib/silcclient/[idlist.h|client_channel.c].
3311 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3313 * Added check to the silc_server_new_id_real to not accept
3314 new ID if it is the sender's own ID. Affected file is
3315 silcd/packet_receive.c.
3317 * Assure that we do not announce ourself or the one we've
3318 sending our announcements when we're router and are announcing
3319 servers to our primary router. Affected file silcd/server.c.
3321 * Fixed silc_server_command_identify_check_client to assemble
3322 correct WHOIS packet. It send corrupted WHOIS packet and
3323 caused problem with router to router connections. Affected
3324 file silcd/command.c.
3326 Fixed also silc_server_command_whois_check the same way
3327 as for the IDENTIFY command.
3329 * Added new SilcIDListStatus to the server in the SilcIDListData
3330 structure. The status now includes the current status of
3331 the entry (like registered, resolved etc.). Affected file
3332 silcd/idlist.[ch]. Defined a bunch of different status types
3333 as well. This replaced the old boolean registered field as well.
3335 Added resolve_cmd_ident field to the SilcClientEntry structure
3336 too so that if the entry is for example being resolved so
3337 another command may attach to the same pending command reply
3338 without requiring to resolve the same entry again. This concept
3339 should optimize the WHOIS and the IDENTIFY resolving under
3340 heavy load by taking away unnecessary resolving for entries
3341 that are being resolved already.
3343 Added support for adding multiple pending commands for one
3344 command idenfier. Affected file silcd/command[_reply].[ch].
3346 * Fixed WHOIS and IDENTIFY save to remove the cache entry
3347 before deleting the data. Otherwise the hash table will have
3348 freed data in comparison functions. Affected file is
3349 silcd/command_reply.c.
3351 * Fixed silc_idlist_replace_client_id to add the new entry to
3352 the cache with NULL nickname. Otherwise there will be invalid
3353 memory as the nickname after the nickname is freed. Affected
3354 file silcd/packet_receive.c.
3356 * Fixed the silc_idlist_get_clients_by_hash. The entries was
3357 saved into wrong slots because the previous number of entries
3358 was not taken into account. Affected file silcd/idlist.c.
3359 Fixed same thing in silc_idlist_get_clients_by_nickname too.
3361 * If we are router and we receive JOIN notify to a channel that
3362 does not have any users then notified client is marked as the
3363 channel founder, as it is it. The affected file is
3364 silcd/packet_receive.c
3366 * Added to the extended hash table API's table_del_*ext functions
3367 the destructor as argument too, so that the caller can decide
3368 which destructor to use or whether to use destructor at all.
3369 Affected file lib/silcutil/silchashtable.[ch].
3371 * Fixed ID Cache purging. It actually deleted the entries from
3372 the hash table after the data was freed. The hash table ended
3373 up comparing freed memory. The affected file is
3374 lib/silccore/silcidcache.c.
3376 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3378 * Fixed Irssi SILC client's KILL command's HELP syntax.
3380 * The USERS command now resolves the detailed user information
3381 if the userinfo field is missing. Affected file is
3382 lib/silcclient/command_reply.c.
3384 * Do not print error in silc_file_read if the read file does
3385 not exist. Just silently return NULL. Affected file is
3386 lib/silcutil/silcutil.c.
3388 * Fixed the silc_log_output to not wine about NULL filename
3389 and to not create some bogus " " filename. Affected file is
3390 lib/silcutil/silclog.c.
3392 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3394 * Fixed various printing bugs on the user interface in the
3395 Irssi SILC Client. Minor changes that were forgotten from
3398 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3400 * Fixed the configure.in.pre and the compilation and distribution
3401 environment to support the new autoconf 2.52. That version is
3402 now required to compile the CVS trunk.
3404 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3406 * Renamed function silc_parse_nickname to silc_parse_userfqdn
3407 to generally parse user@fqdn format strings. Affected file
3408 lib/silcutil/silcutil.c.
3410 * Added nickname_format and nickname_force_format fields to the
3411 SilcClientParams structure. The first one defines the format
3412 for the nicknames that the library will enforce if the receives
3413 multiple same nicknames. The second one is boolean value and
3414 can be used to force the library to always enforce the format
3415 to the nicknames regardles whether there are multiple nicknames
3416 or not. This configurable formatting was employed to flexibly
3417 support accessing multiple nicknames from the user interface.
3418 The userinterface can now set the nicknames to what ever format
3419 they prefer. Affected file lib/silcclient/silcapi.h.
3421 Added function silc_client_nickname_format to the file
3422 lib/silcclient/idlist.c. It performs the nickname formatting.
3424 Added new field `hostname´ to the SilcClientEntry context.
3425 It holds the hostname of the client. Affected file is
3426 lib/silcclient/idlist.h.
3428 * Irssi SILC Client sets the nicknames in nick@hostn format.
3429 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
3430 irssi/src/silc/core/silc-core.c.
3432 The WHOIS printing now also shows both the real nickname and
3433 the formatted nickname so that user knows how to access the
3434 user if there are multiple same nicknames cached. Affected
3435 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
3436 printing formatting too to take the hostname now as a separate
3437 argument. The Affected file is
3438 irssi/src/fe-common/silc/modules-formats.[ch].
3440 * Changed the silc_client_get_clients_local to accept the formatted
3441 nickname as argument. It accepts the real nickname too but the
3442 formatted nickname can be used to find the true entry from
3443 multiple entries. Affected file lib/silcclient/silcapi.h and
3444 lib/silcclient/idlist.c.
3446 * Added nickname_format_parse field to the SilcClientParams.
3447 It is a callback function provided by the application to parse
3448 the nickname out of the formatted nickname string. The library
3449 calls it to get the nickname from the formatted string. Since
3450 the application generally knows better the format of the nickname
3451 string it parses it instead of the library, even though library
3452 encodes the formatted string. If the callback function is not
3453 provided then the library will use the string as is. The
3454 affected file is lib/silcclient/silcapi.h.
3456 * All the nickname strings passed to the client library in
3457 commands are now expected to be formatted nickname strings.
3458 If the command does not support the formatted nickname string
3459 it will assume that the sent string is the actual nickname.
3460 Affected file lib/silcclient/command.c.
3462 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3464 * Added public key authentication support to OPER and SILCOPER
3465 commands in the client library. Affected file is
3466 lib/silcclient/command.c.
3468 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3470 * Changed the get_auth_methdod client operation to be asynchronous.
3471 It can be async if the application resolves the authentication
3472 method from the server during the negotiation. Added new
3473 SilcGetAuthMeth completion callback that the application will
3474 call after resolving the authentication method.
3476 Added function silc_client_request_authentication_method that
3477 the application can use to resolve the authentication method
3478 from the server. Added also SilcConnectionAuthRequest callback
3479 that the library will call after the server has replied. The
3480 application can call this function if it does not know the
3481 current authentication method.
3483 Affected files are lib/silcclient/client.c and
3484 lib/silcclient/silcapi.h.
3486 * The Irssi SILC client now automatically resolves the authentication
3487 method incase any configuration information is not present (and
3488 currently there never is). The affected file is
3489 irssi/src/silc/core/client_ops.c.
3491 * Fixed public key authentication from the client library.
3492 Affected file lib/silcclient/protocol.c. Changed also the
3493 protocol specification about the public key authentication in
3494 the connection authentication protocol. The actual data to be
3495 signed is now computed with a hash function before signing.
3497 * Fixed the public key authentication from the server as well.
3498 Affected file silcd/protocol.c.
3500 * Removed the mlock()'s from the memory allocation routines.
3501 Affected file lib/silcutil/silcmemory.c. The ./configure does
3502 not check anymore for the mlock(). Affected file is
3505 * Fixed USERS command in server to allow the execution of the
3506 command for private and secret channels if the client sending
3507 the command is on the channel. Affected file silcd/command.c.
3509 * Fixed silc_client_get_clients_local to return the clients
3510 count correctly. It could return wrong value. Affected file
3511 lib/silcclient/idlist.c.
3513 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3515 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
3516 types. The assembler optimizations seemed not to like 64-bit
3517 data types. The assmebler optimizations thus are now enabled
3518 also for BSD systems as opposed to only enable them for Linux.
3520 * Do not check for threads at all on BSD systems. Affected
3521 file configure.in.pre.
3523 * Removed -n and -h options from the Irssi SILC Client since
3524 they are not used in silc.
3526 * Fixed the prime generation to assure that the first digit
3527 of the generated random number is not zero since our conversion
3528 routines does not like number strings that starts with zero
3529 digit. If zero digit is seen the random number is regenerated.
3530 This caused some corrupted RSA keys when the zero first digit
3531 was met. Affected file lib/silcmath/silcprimegen.c.
3533 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3535 * Fixed WIN32 configuration in the ./configure script.
3536 Fixed to include xti.h on environments that has it.
3537 Patches by Carsten Ilchmann and andrew.
3539 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3541 * Changed the silc_id_create_client_id to be collision
3542 resistant. It is now assured that there cannot be created
3543 two same client ID's. I suspect that some weird bugs in
3544 the server were actually caused by duplicate Client IDs.
3545 Affected file silcd/serverid.[ch]. A router receiving
3546 new ID now also assures and informs the sending server
3547 if the ID caused collision.
3549 * Changed the silc_id_create_channel_id to also assure that
3550 there are no collisions.
3552 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3554 * Statement about ignoring the Mutual Authentication flag when
3555 performing rekey with PFS was a bit misleading. It is ignored
3556 if it was set in the initial negotiation, it cannot be even
3557 set in the rekey. Fixed in the ke-auth draft. Started the
3558 new versions of the protocol drafts in the doc/.
3560 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3562 * Fixed a bug in silc_client_command_identify_save when saving
3563 new channel information. The channel name was no duplicated
3564 and caused crash on exit. Affected file is
3565 lib/silcclient/command_reply.c.
3567 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3569 * Fixed the getkey command handling in the server. Send just
3570 empty OK reply to the sender if the key could not be fetched
3571 (but everything else was ok, like the key just was not available).
3572 Changed the public key parameter to optional in the protocol
3573 specs so that empty OK reply can be sent. Affected file
3576 Added a message to Irssi SILC client to tell to user if the
3577 server did not return a public key.
3579 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3581 * Fixed a channel key regeneration bug. It registered new
3582 timeout tasks exponentially until all system resources were
3583 used. Affected file silcd/server.c.
3585 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3587 * Added the SILC Document generator to the scripts/silcdoc.
3588 It can be used to generate the Toolkit Reference Manual out
3589 of the source tree. Internally it will also use the RoboDoc
3590 generator now imported in util/robodoc.
3592 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3594 * Added couple of return's in rekey protocol if error orccurred
3595 during the protocol. The execution must be terminated.
3596 Affected file silcd/protocol.c. Also, terminate the protocol
3597 always with timeout.
3599 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3601 * The client's Client ID was created initally from the wrong
3602 nickname (it could have been in format nick@host) in the
3603 silc_server_new_client. Affected file silcd/packet_receive.c
3605 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3607 * Added some SILC_LOG_ERROR's to various error conditions
3608 if client could not be added to ID cache. Affected files
3609 silcd/packet_receive.c and silcd/server.c.
3611 * When client's sock->user_data is freed, NULL also the
3612 client->router and client->connection pointers. Added check
3613 for these pointers being NULL to various places around the
3614 code. Affected file silcd/server.c.
3616 * Added client->data.registered == TRUE checks to various
3617 places around the code to assure that unregistered client's
3618 are not handled when it is not allowed. Affected file
3621 * Added `bool registered' fields to all
3622 silc_idlist_[server|client]_get_* routines to indicate whether
3623 the fetched client needs to be registered or not. Affected
3624 file silcd/idlist.[ch].
3626 * Add your own entry as registered to the ID cache in the
3627 server. Affected file server.c.
3629 * Fixed a bug in silc_server_new_server. The SilcServer was
3630 set as the new server's context instead of SilcServerEntry.
3631 This naturally caused some weird bugs.
3633 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3635 * Do not delete the channel rekey task when adding it
3636 for in silc_server_create_channel_key.
3638 * Changed the silc_server_create_channel_key to return
3639 TRUE or FALSE to indicate the success of the channel key
3642 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3644 * Fixed MSVC++ project files and added missing files to
3645 Makefiles under win32/.
3647 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3649 * Do not add TCP_NODELAY flag if the operating system
3650 does not have it defined. Affected files are
3651 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3653 * Fixed buffer overflow from Irssi SILC Client. Affected
3654 file irssi/src/fe-common/core/themes.c.
3656 * Fixed double free in client library in the file
3657 lib/silcclient/client.c when disconnecting from server.
3659 * Applied double free patch from cras to Irssi SILC client.
3660 Affected files irssi/src/core/[modules/expandos].c
3662 * Fixed the disconnection handling to Irssi SILC Client.
3663 The application must call silc_client_close_connection
3664 in ops->connect client operation in case of failure of
3665 the connection. Affected file is
3666 irssi/src/silc/core/client_ops.c.
3668 * Do not set sock->protocol to NULL in the function
3669 silc_client_close_connection after executing the protocol's
3670 final callback since the sock might not be valid anymore.
3671 Affected file lib/silcclient/client.c.
3673 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3675 * Do not enable SILC_THREADS if the linking with libpthread
3676 did not happen. Affected file configure.in.pre.
3678 * Added notion to protocol specification that server must
3679 verify the sent authentication payload with CMODE when
3680 setting the channel founder key. Implemented it to the
3681 server. Affected file silcd/command.c.
3683 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3685 * Added _EXTRA_DIST SILC distribution variable to the
3686 distributions file. It is used to conditionally add extra
3687 files or directories to the specific distribution. Affected
3688 files ./prepare, Makefile.am.pre and distributions.

3693 * Added README.WIN32 for instructions to compile the Toolkit
3696 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3698 * Fixed a double free in disconnection in the server. Affected
3699 file is silcd/server.c.
3701 * Fixed the lib/silcske/groups.c to work now also with GMP
3702 MP library. The string conversion did not work when using
3703 specific base and the base is indicated in the string as well.
3705 * Created win32/ directory which now includes MSVC++ specific
3706 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3707 It will appear only in the toolkit distribution
3709 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3711 * Changed the key material distribution function in case when
3712 the hash output is too short. The data is now concatenated
3713 a bit differently than it used to. Made the change to the
3714 SKE protocol specification.
3716 * Added better GMP detection to configure.in.pre. A patch
3719 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3721 * Fixed a minor bug in SKE that might cause some problem on
3722 some platforms. Affected file lib/silcske/silcske.c.
3724 * Added the cookie checking for initiator in the SKE. It checks
3725 that the responder returns the sent cookie unmodified. The
3726 affected file is lib/silcske/silcske.c. Added new SKE
3727 error type INVALID_COOKIE that can be sent during the
3728 negotiation. Fixed some memory leaks as well.
3730 * Added the "invalid cookie" error message to Irssi SILC client's
3733 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3735 * Added `task_max' field to the SilcClientParams to indicate
3736 the maximum tasks the scheduler can handle. If set to zero,
3737 default values are used. Affected file lib/silcclient/silcapi.h.
3739 * Fixed memory leaks in silc_client_close_connection. Affected
3740 file lib/silcclient/client.c.
3742 * Added silc_client_del_client_entry to client library to free
3743 all memory of given client entry. Affected file is
3744 lib/silcclient/idlist.[ch].
3746 * Added new functions silc_client_del_channel and
3747 silc_client_del_server to delete channel and server entries.
3748 Affected file lib/silcclient/[silcapi.h/idlist.c].
3750 * Removed silc_client_del_client_by_id from silcapi.h.
3752 * Fixed the INFO command to return the server's own info
3753 correctly when querying by Server ID. Affected file is
3756 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3758 * Removed the non-blocking settings in WIN32 code in the
3759 silc_sock_[read/write] and added SleepEx instead. Affected
3760 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3761 of input data is now checked with FIONREAD and ioctlsocket.
3763 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3765 * Call silc_schedule_task_del_by_context in the
3766 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3767 Affected file lib/silccore/silcprotocol.c.
3769 * Call silc_protocol_cancel for active protocols in the
3770 silc_server_close_connection if the funtion
3771 silc_server_free_sock_user_data has not been called.
3772 Affected file silcd/server.c.
3774 * Generic tasks cannot be deleted using the del_by_fd
3775 task deleting function since generic tasks does not match
3776 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3778 * Added a notion to SILCOPER help file that the SILCOPER works
3779 only on router server, not on normal server.
3781 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3783 * Added for WIN32 support for the new scheduler as well.
3784 Affected file lib/silcutil/win32/silcwin32schedule.c.
3786 * Fixed the SHA1 implementation to work on various platforms.
3788 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3790 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3791 API. It is part of the scheduler now. Everything else is
3792 as previously but some functions has changed their names.
3793 Checkout the lib/silcutil/silcschedule.h for the interface.
3794 Updated all applications to use the new interface. Affected
3795 files are lib/silcutil/silcschedule.[ch].
3797 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3799 * Found a bug in the SKE implementation. The HASH value,
3800 specified by the protocol, was not computed correctly. The
3801 public key of the responder was not added to the computation
3802 even though it is mandatory. Affected file lib/silcske/silcske.c.
3803 This unfortunately causes incompatibilities with older
3804 clients and servers.
3806 * Added WIN32 specific network init and uninit functions:
3807 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3808 the Winsock2. Affected file lib/silcutil/silcnet.h and
3809 lib/silcutil/win32/silcwin32net.c.
3811 * Set the socket always to nonblocking mode on WIN32 after
3812 reading data or writing data. Affected file is
3813 lib/silcutil/win32/silcwin32sockconn.c.
3815 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3817 * Fixed various compilation problems under WIN32. Affected
3818 files lib/silcutil/win32/silcwin32thread.c and
3819 lib/silcutil/win32/silcwin32schedule.c.
3821 * Removed all _internal.h #includes from public header
3822 files. Internal headers must never be included from
3825 Removed also the lib/silcske/payload_internal.h file.
3827 * All include files that may be needed (public and some others
3828 included by the public headers) by application developers are
3829 now copied to the ./includes directory. It does not copy any
3830 internal headers. Affected file Makefile.defines.pre and all
3831 Makefile.am's under lib/ and subdirs.
3833 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3835 * Do not change the ~/.silc directory's permissions automatically.
3836 Affected file irssi/src/silc/core/clientutil.c.
3838 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3840 * Do not cancel the protocol in silc_server_close_connection
3841 it might cause recursion. Now cancelled in the function
3842 silc_server_free_sock_user_data. Affected file silcd/server.c.
3844 * Fixed the silc_server_remove_clients_by_server to regenerate
3845 the channel keys correctly finally. Added also new function
3846 silc_server_remove_clients_channels to actually do it.
3847 Affected file silcd/server.c.
3849 * Fixed the silc_server_new_channel to not crash by giving
3850 wrong router to the new channel. Affected file is
3851 silcd/packet_receive.c.
3853 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3855 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3856 which is given as argument to the silc_client_alloc now.
3857 It can be used to configure the client and set various parameters
3858 that affect the function of the client.
3860 * The USERS command in server did not check whether the channel
3861 is private or secret. Affected file silcd/command.c.
3863 * Added new argument to the USERS command in protocol specification.
3864 The USERS command now can take the channel name as argument
3865 as well. Added support for this in client and server and
3866 updated the protocol specs.
3868 * Completed the GETKEY command in client. It can be now used
3869 to fetch also servers public key not only some clients.
3870 Affected files lib/silcclient/command[_reply].c.
3872 * Added silc_client_get_server to return server entry by the
3873 server name. Affected files lib/silcclient/silcapi.h and
3876 * Redefined the IDENTIFY command in protocol specification to be
3877 more generic. It now can be used to query information about
3878 any entity in the SILC Network, including clients, servers and
3879 channels. The query may be based either the entity's name
3880 or the ID. Added support for this in both client and server.
3882 Affected files silcd/command.c and lib/silcclient/command.c
3883 and command_reply.c.
3885 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3886 the _from_client and _from_server functions. Affected file
3889 * Added silc_client_get_channel_by_id_resolve to the file
3890 lib/silcclient/silcapi.h to resolve channel information by
3891 its ID. Added also silc_client_get_channel_by_id that
3892 does not resolve it from the server.
3894 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3896 * Added SilcServerEntry context into the client library
3897 to represent one server. The INFO command now allocates
3898 these to save the resolved server info. For now on the
3899 client library will also keep information about servers,
3900 connected and resolved with INFO.
3902 The INFO command now allocates the SilcServerEntry context
3903 and saves the server info there. The COMMAND_REPLY in
3904 the INFO now returns the parameters to application in
3905 same order as defined in the protocol specification.
3907 The entries are cached in the client->server_cache.
3909 * The INFO command is now issued after received the Client ID
3910 from the server. Affected file lib/silcclient/client.c.
3912 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3913 to the application as the mode changer might be server.
3914 It is guaranteed that NULL is not returned anymore to the
3915 application. Affected file lib/silcclient/client_notify.c.
3917 The ID Type is now also passed to the application so that
3918 it can check whether the returned entry is SilcClientEntry
3921 Added new function silc_client_get_server_by_id to return
3922 the server entry by ID. Affected files are the
3923 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3925 * Do not create the channel in the Irssi SILC Client when issuing
3926 the JOIN command but when received the sucessful JOIN command
3927 reply. Otherwise the channel might get created even though we
3928 could not join it. The Affected file is
3929 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3931 * Fixed a channel joining bug in router. The router must also
3932 check the channel modes, invite and ban lists etc. when serving
3933 the JOIN command sent by normal server. Affected file is
3934 silcd/command.c. The router now resolves the client's
3935 information from the server who sent the JOIN command if it
3936 does not know it, and processes the JOIN command only after
3939 * Changed the SilcCommandCb to take new argument; void *context2.
3940 Affected file lib/silccore/silccommand.h
3942 The second argument in the command callbacks in the server now
3943 includes the SilcServerCommandReplyContext if the command was
3944 called as pending command callback from the command reply.
3945 Otherwise it is NULL. When called as pending the status of the
3946 command reply will be checked and if it was erronous the
3947 error will be sent to the original sender of the command.
3948 This way the client always receives the error messages even
3949 though the server was actually the one who received the error
3950 when it resent the command to router, for example. Affected
3951 files silcd/command[_reply].[ch].
3953 * Fixed sending WHOWAS command's error message to client if
3954 the requested client could not be found. It was missing.
3957 * Changed the CMODE and CUMODE commands reply arguments in the
3958 protocol specification. The Channel ID is now sent in both
3959 of the commands to identify the channel. Implemented this
3960 new feature to the client and server. Affected files
3961 lib/silcclient/command_reply.c and silcd/command.c.
3963 * Made better checks for invite and ban lists in the JOIN
3964 command in server. Affected file silcd/command.c.
3966 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3968 * The server now performs the incoming host IP/DNS lookup
3969 using the silc_socket_host_lookup and thus does not block
3970 the server anymore. Affected file silcd/server.c.
3972 * Completed the multi-thread support for SILC Scheduler in
3973 the lib/silcutil/silcschedule.c.
3975 * Fixed the configure.in.pre to detect the pthread correctly
3978 * Fixed a deadlock in silc_task_queue_wakeup in the file
3979 lib/silcutil/silctask.c.
3981 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3983 * Added new function silc_schedule_wakeup that is used in
3984 multi-threaded environment to wakeup the main thread's
3985 schduler. It needs to be used when a thread adds a new task
3986 or removes a task from task queues. After waking up, the
3987 scheduler will detect the task queue changes. If threads
3988 support is not compiled in this function has no effect.
3989 Implemented the wakeup mechanism to both Unix and WIN32
3990 systems. Affected files are lib/silcutil/silcschedule.[ch],
3991 lib/silcutil/unix/silcunixschedule.c and the
3992 lib/silcutil/win32/silcwin32schedule.c.
3994 * Added new function silc_task_queue_wakeup to wakeup the
3995 scheduler by the specified task queue. Affected file
3996 lib/silcutil/silctask.[ch].
3998 * The silc_socket_host_lookup_start now wakes up the scheduler
3999 after adding the timeout task. Affected file is
4000 lib/silcutil/silcsockconn.c.
4002 * The silc_socket_host_lookup is synchronous now if the threads
4003 support is not compiled in. However, the callback is still
4004 called asyncronously through the scheduler, anyway. Affected
4005 file lib/silcutil/silcsockconn.c.
4007 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4009 * Added new function silc_socket_host_lookup to perform
4010 asynchronous IP and FQDN lookups for the socket connection.
4011 Affected files lib/silcutil/silcsockconn.[ch].
4013 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4015 * Added SILC_MUTEX_DEFINE to define the mutex on environments
4016 that may or may not compile the mutex support in.
4018 Changed the silc_mutex_alloc interface. It allocates the
4019 mutex now to the sent pointer and returns TRUE or FALSE.
4021 Affected file lib/silcutil/silcmutex.h.
4023 * Wrote the SILC Task Queue interface to support multi-threads.
4024 Affected file lib/silcutil/silctask.[ch].
4026 * Wrote the SILC Scheduler to support multi-threads. Affected
4027 file lib/silcutil/silcschedule.c.
4029 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4031 * Implemented the SILC Mutex API and SILC Thread API for WIN32
4032 in lib/silcutil/win32/.
4034 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4036 * Defined SILC Mutex API and SILC Thread API and implemented
4037 them for Unix. Affected files are
4038 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
4039 lib/silcutil/unix/silcunixmutex.c and
4040 lib/silcutil/unix/silcunixthread.c.
4042 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4044 * Fixed the silc_server_remove_clients_by_server's channel
4045 key re-generation. The hash table handling was incorrect
4046 and would not work with many channels. Affected file is
4049 * Fixed some memory leaks around the server code.
4051 * Rewrote the silc_server_get_users_on_channel to support IPv6
4052 based Client ID's. Affected file silcd/server.c.
4054 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
4055 specification. However, a separate document must be written
4056 to define the detailed signing procedure and the payload
4057 associated with the flag. Defined the flag to the
4058 lib/silccore/silcchannel.h as well.
4060 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4062 * Changed the dynamic tables to static size tables in the
4063 lib/silccrypt/silchmac.c.
4065 * Removed GCC dependencies from the code. A patch by cras.
4067 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4069 * Do not show the error "Error receiving packet bla bla"
4070 in server if it really was not an error (-2 means that reading
4071 is pending). Affected file silcd/server.c.
4073 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4075 * Fixed a possible crash in silc_server_remove_clients_by_server
4076 in silcd/server.c. Fixed there also some memory leaks.
4078 * Fixed the silc_idlist_replace_client_id. It could replace
4079 wrong key in the hash table. Affected file silcd/idlist.c.
4081 * Do not check whether there are global users on the channel
4082 if the channel->global_users is FALSE. Affected functions
4083 silc_server_remove_from_one_channel and
4084 silc_server_remove_from_channels in silcd/server.c. Also,
4085 do not check if the removed client is local as we can be
4086 sure that global client was not removed from the channel
4087 and checking for global users is not needed.
4089 * The silc_server_remove_clients_by_server now re-generates
4090 the channel keys correctly for those channels that had
4091 clients removed from them. Affected file silcd/server.c.
4093 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4095 * Found the reason of random crashes in the server. We weren't
4096 ignoring the SIGPIPE signal (which can be sent in write())
4097 and it crashed the server. Affected file silcd/silcd.c.
4099 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4101 * Assure that sock->user_data is not NULL in the function
4102 silc_server_packet_send in silcd/packet_send.c.
4104 * Disconnect the remote connection if it could not be added
4105 to any ID lists in the server. The affected file is
4108 * Check in silc_server_packet_send[_real/dest] that the
4109 socket is not disconnecting and ignore the data if it is.
4110 Affected file silcd/packet_send.c.
4112 * Define inline to __inline on native WIN32 compilation.
4113 Affected file includes/silcwin32.h.
4115 * Added some explicit type casts for inline code since MSVC
4116 require them. Affected files lib/silcutil/silcbuffer.h,
4117 lib/trq/silcdlist.h and lib/trq/silclist.h.
4119 * Print warning in log files from now on if the packet
4120 decryption fails. Affected file silcd/server.c.
4122 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4124 * Changed the `say' client operation's interface to accept
4125 new `type' argument to indicate the type of the message sent
4126 by the library. The application may filter the library's
4127 messages according the type. The affected file is the
4128 lib/silcclient/silcapi.h.
4130 * Added two new functions to lib/silcclient/silcapi.h:
4131 silc_client_del_client and silc_client_del_client_by_id.
4132 Affected file lib/silcclient/idlist.c.
4134 * Moved the clientincludes.h from includes/ to silc/ and
4135 serverincludes.h from includes/ to silcd/.
4137 * The modes for the CMODE and CUMODE are now passed as
4138 uint32 for application with COMMAND_REPLY. The affected
4139 file is lib/silcclient/command_reply.c.
4141 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4143 * /WHOIS without arguments shows client's own information.
4144 Affected file lib/silcclient/command.c.
4146 * Changed PING to not accept any arguments. The specs
4147 says that client can ping only the connected server so
4148 requiring an argument is not needed. Affected file is
4149 lib/silcclient/command.c.
4151 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4153 * Fixed a fatal bug in private message sending and reception
4154 encryption and decryption when using private message keys.
4155 The implementation was incorrect and did not follow the
4156 specification. It causd that some of the message were
4157 lost since it did not use the sending and receiving keys
4158 as the protocol suggests. This has been fixed and will cause
4159 incompatibilities with older clients when sending private
4160 message encrypted with private message keys. Affected files
4161 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
4162 and various other in Irssi SILC Client.
4164 Added `responder' boolean argument to the functions
4165 silc_client_add_private_message_key[_ske] to indicate when
4166 the key is added as responder or initiator of the key
4169 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4171 * Removed the silc_ske_check_version function and created
4172 a SilcSKECheckVersion callback. Added also a function
4173 silc_ske_set_callbacks that is now used to set all SKE
4174 callbacks. The callback functions are not given to
4175 the SKE functions anymore, but this function is used to
4178 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
4180 * Added `silc_version' argument to the silc_client_alloc
4181 to define the version of the application for the library.
4182 The library will use the version string to compare it
4183 against the remote host's (usually a server) version
4184 string. Affected file lib/silcclient/silcapi.h
4186 * Added the KE protocol context to Key Agreement context
4187 in client library so that we can abort the SKE if it
4188 is in process when we get timeout. Affected file is
4189 lib/silcclient/client_keyagr.c.
4191 * Do not resolve the client ID forever if it returns in the
4192 first time that such client does not exist. This was done
4193 for example with private message. Affected file is
4194 lib/silcclient/client_prvmsg.c.
4196 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4198 * Do not add regex.h for WIN32. The affected file
4199 includes/silcincludes.h.
4201 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
4202 not work yet 100%. It generates the DLL's automatically
4203 when compiling with --with-win32 under cygwin.
4205 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4207 * lib/contrib/regex.c is not compiled on WIN32.
4209 * Added silc_net_get_socket_opt function to the
4210 lib/silcutil/silcnet.h.
4212 * Added includes/silcwin32.h for WIN32 specific includes
4215 * Do not use ptime structure or any of the posix process
4216 functions on WIN32 in lib/silccrypt/silrng.c.
4218 * Added silc_gettimeofday to provide generic function
4219 for struct timeval on all platforms. Added the function
4220 to lib/silcutil/silcutil.h.
4222 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4224 * Moved the lib/silccore/silcsockconn.[ch] to the utility
4225 library as they clearly belong there. As a plus side we
4226 can make the actual socket connection routines platform
4229 Added also new generic function silc_socket_read and
4230 silc_socket_write (that used to be silc_packet_[read/write].
4231 The implementation of these are platform specific.
4233 * Added WIN32 specific routines of silc_socket_[read/write]
4234 to lib/silcutil/win32/silcwin32sockconn.c.
4236 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4238 * Added preliminary support for native WIN32 compilation under
4239 cygwin (using the -mno-cygwin option for GCC) to the
4240 ./configure.in.pre. The --with-win32 now prepares the
4241 compilation for native WIN32.
4243 * Rewrote the SILC Scheduler interface in the file
4244 lib/silcutil/silcschedule.h. The scheduler is now context
4245 based and does not have anymore any global static scheduler.
4246 Moved the Unix scheduler to the lib/silcutil/unix/ directory
4247 and created lib/silcutil/win32 directory for WIN32 based
4250 * Added Unix specific network routines to the
4251 lib/silcutil/unix/silcunixnet.c and the old
4252 lib/silcutil/silcnet.c includes now only generic routines.
4254 Added WIN32 specific network routines to the
4255 lib/silcutil/win32/silcwin32net.c.
4257 * Added Unix specific utility functions from the
4258 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
4260 * Added WIN32 SILC Scheduler to the file
4261 lib/silcutil/win32/silcwin32schedule.c. The code is of course
4264 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4266 * Do not handle JOIN notify in the server if the target client
4267 is not registered (idata->registered == FALSE). The affected
4268 file is silcd/packet_receive.c.
4270 * Update the nickrec->founder in event_cumode in the Irssi SILC
4271 client. Affected file irssi/src/silc/core/silc-channels.c.
4273 * Fixed the CUMODE_CHANGE notify handling in the server when
4274 server and router are announcing their clients on channels.
4275 Now the mode changes are saved and notified correctly. The
4276 affected file is /silcd/packet_receive.c.
4278 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
4279 They really did not replace the cache entry in the ID Cache.
4280 Now they do that. Affected file silcd/idlist.c.
4282 * Fixed the KICK notify handling in the Irssi SILC client to
4283 update the channel records so that the kicked client does not
4284 appear to be on the channel. The affected file is
4285 irssi/src/silc/core/silc-channels.c.
4287 * Always update the conn->current_channel when executing command
4288 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
4290 * Fixed the KILL notify handling in Irssi SILC client to remove
4291 the killed client on all channels.
4293 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4295 * Fixed the silc_parse_command_line to remove extra spaces
4296 from the start and end of the arguments. Affected file is
4297 lib/silcutil/silcutil.c.
4299 * Cancel and free any active protocol in the function
4300 silc_server_close_connection. Affected file silcd/server.c.
4302 * Cancel and free any active protocol in the function
4303 silc_client_close_connction. Affected file is
4304 lib/silcclient/client.c.
4306 * Do not execute the KILL command for clients that are in
4307 history (ie. they are not in the network). Affected file is
4310 * Fixed KILL notify handling, client does not crash anymore.
4311 Affected file irssi/src/silc/core/silc-channels.c.
4313 * Reduced the default packet buffer size from 2048 to 1024 in
4314 lib/silccore/silcpacket.c.
4316 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
4317 counter to the SKE context that is incresed when the SKE library
4318 performs async operation outside the library. If the outside
4319 process frees the SKE context and FREED status will be set
4320 and the library will detect after the sync operation that the
4321 libary is freed. The affected files are
4322 lib/silcske/silcske[_status].[ch].
4324 * Resolve the client entry information in the function
4325 silc_client_channel_message to assure that NULL pointer is not
4326 passed as client entry to the application. */
4328 * Fixed the task timeout calculation to assure that there is
4329 never negative timeouts. The affected file is
4330 lib/silcutil/silcschedule.c.
4332 * Fixed the channel user mode notification sending in server.
4333 It was sent point-to-point to the router (or to server by router)
4334 but it needs to be destined to a channel. The routines now
4335 supports sending the channel user mode notifys to the channels
4336 when announcing clients and channels. Affected files are
4337 silcd/server.c and silcd/packet_receive.c.
4339 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
4340 It did not actually replace the old channel entry in the cache.
4341 Affected file lib/silcclient/client_notify.c.
4343 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4345 * Fixed a possible crash in silc_packet_send_prepare. It now
4346 assures always that there is enough space in the buffer and
4347 at the tail area of the buffer (for MAC).
4349 Fixed the inbound buffer reallocation in silc_packet_read.
4350 It was old code and did not handle the reallocation correctly.
4353 The affected file is lib/silccore/silcpacket.c.
4355 * Fixed buffer overflow in silc_parse_nickname in the file
4356 lib/silcutil/silcutil.c.
4358 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4360 * make install generates new server keys only if there is not
4363 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4365 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
4366 Added check that if the NOREPLY is set then we will not send
4367 the away message. This avoids infinite loop of away messages
4368 if both clients are away. The affected file is
4369 lib/silcclient/client_prvmsg.c.
4371 * Fixed client crash if /NICK was given without arguments.
4372 Affected file lib/silcclient/command.c.
4374 * Server does not send the invite list in INVITE command back
4375 to the client if the list was not altered. Added this notion
4376 to the protocol spec as well. Affected file silcd/command.c.
4378 Fixed possible crash in INVITE command by checking the
4379 value of silc_server_get_client_route command.
4381 * Fixed the INVITE notify type handling. The arguments are now
4382 taken in correct order and client does not crash. The affected
4383 file is irssi/src/silc/core/silc-channels.c.
4385 Removed the "Inviting xxx to channel" message from the
4386 client library away and let the application handle it.
4387 Affected file lib/silcclient/command.c. Added that message
4388 to Irssi SILC client's message formats.
4390 * Fixed CMODE command crash in client. It now checks the
4391 amount of arguments correctly and does not crash. The affected
4392 file is lib/silcclient/command.c.
4394 * Do not create new channel automatically in silc_channels_join
4395 but check whether the channel by that name already exists.
4396 Affected file irssi/silc/core/silc-channels.c.
4398 * Do not send the SERVER_SIGNOFF to router if the disconnected
4399 entity was the router. Affected file silcd/server.c.
4401 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
4402 SILC client as it was missing from there.
4404 Added the handling of the KICK notify to the Irssi SILC client
4405 as it was missing. Added "you have been kicked" message to
4406 Irssi SILC client's message modules formats.
4408 Added the handing of the KILL notify to the Irssi SILC client
4409 as it was missing. Added the kill message module formats
4412 The affected file is irssi/src/silc/core/silc-channels.c.
4414 * The router did not save the channel mode the server announced.
4415 Affected file silcd/packet_receive.c.
4417 * Fixed a possible crash in INFO command in server. If the
4418 server did not provide the server info it crashed. Affected
4419 file silcd/command.c.
4421 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4423 * Fixed the GETKEY command in the server to check also the
4424 global list. Otherwise the GETKEY would not work correctly
4425 in normal SILC server. Affected file silcd/command.c.
4427 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4429 * Fixed GETKEY crash, it crashed if the command did not succseed.
4431 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4433 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
4434 is now real and not just an macro interface to GMP.
4436 Removed the entire GMP from the source tree and imported new
4437 NSS MPI library instead. Reason for removing GMP is that it is
4438 extremely large and compiles extremely slow. The NSS MPI
4439 is only a few files and compiles in less than 10 seconds.
4440 The speed is also about the same as GMP. The MPI is imported
4441 to lib/silcmath/mpi.
4443 If the system has GMP installed we will still use the GMP.
4444 If it is not then the NSS MPI will be compiled.
4446 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4448 * Merged a long nickname (127 characters long) crash bugfix from
4449 Irssi CVS tree. Affected file irssi/src/core/misc.c.
4451 * Merged a freed memory reference bugfix from Irssi CVS tree.
4452 Affected file irssi/src/core/commands.c.
4454 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4456 * Added the server's public key sving and verification to the
4457 server when performing the SKE. This was missing and the
4458 remote server's (or router's) public key was accepted without
4459 checking whether we have it previously or trust it at all.
4460 Affected file silcd/protocol.c.
4462 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4464 * Check in the silc_server_timeout_remote if protocol is active
4465 and make sure that the protocol's final callback is called so
4466 that all memory if freed. Affected file silcd/server.c.
4468 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4470 * silc_server_whois_send_reply crashed the server if the nickname
4471 was 127 characters long. Affected file silcd/command.c.
4473 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4475 * Added sanity check to the silc_server_new_client. If the hostname
4476 is provided inside username then check that the provided hostname
4477 really is the same as the resolved one. If the hostname was not
4478 resolved then check it from the public key. Affected file is
4479 silcd/packet_receive.c.
4481 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
4482 if the server disconnected us and the connection is not valid
4483 anymore. Affected file irssi/src/silc/core/silc-channels.c.
4485 * Moved the silc_client_[chmode|chumode|chumode_char] away from
4486 the library to the lib/silcutil/silcutil.[ch].
4488 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4490 * Close log file after open. Affected file
4491 lib/silcutil/silclog.c.
4493 * Check whether sock == NULL in silc_client_send_packet and return
4494 if it is. Affected file lib/silcclient/silcclient.c.
4496 * Check rec->entry == NULL in the Irssi SILC Client before
4497 sending the channel message. Affecte file is
4498 irssi/src/silc/core/silc-servers.c.
4500 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4502 * Merged a splitted window bugfix from Irssi CVS tree. The
4503 affected file is irssi/src/fe-text/textbuffer-view.c.
4505 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
4506 It did not print nickname.
4508 * Improved the distributions system a bit.
4510 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4512 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
4513 irssi/src/fe-text/gui-window.c.
4515 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
4516 to in-active server. The affected file is
4517 irssi/src/silc/core/client_ops.c.
4519 * Resolve the client in USERS command reply if the entry does
4520 not have username resolved. The affected file is
4521 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
4522 command to WHOIS command to really resolve stuff. The USERS
4523 is not used any more in any critical section so WHOIS can
4524 be used even though it might be slower than IDENTIFY.
4526 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
4529 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4531 * Changed the protocol API a bit more consistent in the
4532 lib/silccore/silcprotocol.[ch].
4534 * Changed the following headers to ROBODoc format:
4536 lib/silccore/silcpayload.h
4537 lib/silccore/silcprotocol.h
4538 lib/silccore/silcsockconn.h
4540 All core library headers are now formatted.
4542 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4544 * Fixed a bug in Irssi SILC client; do not show that you are
4545 server/router operator if you really are not. Affected file is
4546 irssi/src/silc/core/client_ops.c.
4548 * Renamed silc_command_free_payload to silc_command_payload_free.
4549 Affected file lib/silccore/silccommand.h
4551 * Added silcmath.h to include the prototoypes of various routines
4552 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
4555 * Changed the following headers to ROBODoc format:
4557 lib/silccore/silcchannel.h
4558 lib/silccore/silccommand.h
4559 lib/silccore/silcid.h
4560 lib/silccore/silcidcache.h
4561 lib/silccore/silcmode.h
4562 lib/silccore/silcnotify.h
4563 lib/silccore/silcpacket.h
4564 lib/silcmath/silcmath.h
4566 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4568 * Added checking to the server code not to start the server if
4569 ciphers and stuff are not configured properly. Affected files
4570 silcd/serverconfig.[h] and silcd/server.c.
4572 * Changed the layout of the header files of the public interfaces
4573 in the SILC libraries. The new layout supports ROBODoc
4574 documentation tool (and some others) so that it is easy to create
4575 a library reference manual. All the other headers and source
4576 code must still follow the CodingStyle document. Also source
4577 code must not include these ROBODoc stuffs, only the headers.
4578 Furthermore, all public interface headers must now be named
4579 by using `silc' prefix, example: silcapi.h, silccipher.h.
4580 Some files were renamed due to this. All the other headers
4581 must not be used as public interfaces. I will update the
4582 CodingStyle document later. Changed following headers, so far:
4584 lib/silcclient/silcapi.h
4585 lib/silccore/silcauth.h
4586 lib/silccore/silcprivate.h
4587 lib/silccrypt/silcdh.h
4589 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4593 * Removed silc_client_packet_send_flush from the client library
4594 as it is not needed. Affected file lib/silcclient/client.[ch].
4596 * Added printing of message of unresolved authentication method
4597 to the Irssi SILC client. Added it to the module formats.
4598 Removed the same message from the client library.
4600 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4602 * Added new distribution feature, DISTLABEL. Every distribution
4603 can define own preprocessor label that can be used in the
4604 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
4605 file distributions, acconfig.h.pre and prepare.
4607 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4609 * Added Makefile.defines_int to include the actual definitions
4610 for Makefile.defines.in. Tested the new distribution system,
4611 created distributions and tested installation.
4613 * Added AWAY message printing to the Irssi SILC client. Added
4614 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
4616 * Added SCONNECT command to call the SILC's CONNECT command.
4617 Cannot use CONNECT directly since Irssi uses that internally.
4618 Affected file irssi/src/silc/core/silc-servers.c.
4620 Added ACTION local command. It is same as ME command but takes
4621 the channel as mandatory argument.
4623 Rewrote some of the Irssi's help files to suite for SILC
4626 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4628 * Added Makefile.defines[.in] that should for now on be included
4629 in all Makefile.am file in the source tree. That file includes
4630 all common compilation definitions for SILC source tree.
4632 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4634 * Minor changes to the ./prepare script to change the package
4635 name according the distribution name to the configure.in.
4637 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4639 * Created new distribution system. Added file `distributions'
4640 that defines all the distributions that can be created out of
4641 the SILC source tree. The ./prepare script now reads that
4642 file to determine how to prepare the distributions. The
4643 first argument to the ./prepare is the name of the distribution
4644 and second is the version of the distribution. If given
4645 without arguments it creates the default (toolkit) distribution
4646 with the default version (defined in ./prepare).
4648 All Makefile.am files that are subject to the distributions
4649 are now named as Makefile.am.pre. These are ./Makefile.am
4650 and lib/Makefile.am. Others may be changed later.
4652 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4654 * Added invite list, ban list, some key management and connection
4655 error message printing to module formats in the Irssi SILC client.
4657 * Added new silc_client_set_away_message to set the away message
4658 that is back to the person who sent private message. The
4659 affected file lib/silcclient/silcapi.h and the
4660 lib/silcclient/client_prvmsg.c.
4662 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4664 * Fixed the private message sending in the Irssi SILC client,
4665 added local command KEY to the Irssi SILC client.
4667 Added key management and key agreement message formats to the
4668 irssi/src/fe-common/silc/module-formats.[ch].
4670 Added USERS (alias WHO) printing, server/router operator
4671 indication and LIST command printing to the module formats.
4673 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4675 * Fixed channel joining notify handling, cumode notify handling
4676 from Irssi SILC client.
4678 * Added SILC specific module-formats to the Irssi SILC client so
4679 that SILC specific message hilighting, colors etc is possible.
4680 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4682 Added channel mode, channel user mode, actions, notices,
4683 whois and whowas printing to the the module-formats.c.
4685 * Fixed a bug in channel deletion in the server. The channel
4686 is not left to the cache even if the channel founder auth mode
4687 is set when there are no users anymore on the channel. Affected
4688 file silcd/server.c.
4690 * The silc_net_localhost now resolves the entire hostname including
4691 the domain name. Affected file lib/silcutil/silcnet.c.
4693 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4695 * Changed the ask_passphrase client operation to be ascynchronous.
4696 It has now a completion callback and a context that the
4697 application must call after it has got the passphrase from
4698 the user. Affected files lib/silcclient/silcapi.h,
4699 lib/silcclient/protocol.c, lib/silcclient/command.c and
4702 Added SilcAskPassphrase callback that the application calls
4703 to deliver the passphrase to the library.
4705 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4706 The public key verification and especially a certificate
4707 verification is asynchronous procedure.
4709 Added new SILC_SKE_STATUS_PENDING status to indicate the
4710 request is pending and a callback will be called to finalize
4713 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4714 indicate that remote end did not send its public key (or
4715 certificate), even though we require it. Added check for this
4716 condition in the SKE. This was a security bug, now fixed.
4718 Defined new SilcSKEVerifyCbCompletion callback that is called
4719 when the verification process is completed.
4721 The affected files lib/silcske/silcske_status.h and
4722 lib/silcske/silcske.[ch].
4724 * Changed the verify_public_key client operation to be async
4725 as well. Defined SilcVerifyPublicKey callback that is used to
4726 indicate the success of the public key verification process.
4728 Changed the server and client to use the new async client
4731 * Changed the Irssi SILC client's internal scheduler to be called
4732 twice as many times as it used to be. As a result the client
4733 should be a bit faster now. Affected file is
4734 irssi/src/silc/core/silc-core.c.
4736 * Added support to Irssi SILC client of asynchronous public key
4737 verification and passphrase inquiry. Affected file is
4738 irssi/src/silc/core/silc-core.c.
4740 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4742 * Do not say "You have left channel %s" in client library.
4743 Moved it to the application. Affected files are
4744 lib/silcclient/command.c and silc/client_ops.c.
4746 * Fixed silc_client_get_clients. Command context was not
4747 duplicated and was freed memory in the callback. Affected
4748 file lib/silcclient/idlist.c.
4750 * Do not say "you are now talking..." on JOIN command in the
4751 client library. The appliation must handle it.
4753 * Do not say ".. changed topic to" in command reply in the
4754 client libary. The application must handle it.
4756 * Fixed TOPIC command sending in the client library.
4758 * Fixed a memory leak in silc_client_command_free in the file
4759 lib/silcclient/command.c.
4761 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4763 * Imported a modified version of Irssi client to the source tree.
4764 The Irssi will be used to create a new client called
4765 Irssi SILC. Imported to irssi/.
4767 Added silc_core_init_finish function to the Irssi. Affected
4768 file irssi/configure.in.
4770 A lot changes in the Makefile.ams around the irssi tree.
4772 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4774 * Do not rehash if the new size is same as the old size of the
4775 hash table, in the silc_hash_table_rehash*. The affected file
4776 lib/silcutil/silchashtable.c.
4778 * Replaced hash_table_del_by_context calls from the server
4779 (when channel->user_list and client->channels) to the
4780 hash_table_del as it is sufficient and faster.
4782 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4784 * Added silc_hash_table_list, silc_hash_table_get and the
4785 SilcHashTableList structure to provide an alternative way to
4786 traverse the hash table. The affected files are
4787 lib/silcutil/silchashtable.[ch].
4789 * Changed the server's idlist routines to use the hash table
4790 routines to optimize the code.
4792 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4794 * Replaced the client entry's `channel' list and channel entry's
4795 `user_list' list to hash tables for optimized lookup. Changed
4796 the code to use the hash table interface around the code.
4797 Affected file lib/silcd/idlist.[ch].
4799 * Added `auto_rehash' boolean argument to the function
4800 silc_hash_table_alloc to indicate whether the hash table should
4801 auto-rehash when it thinks is appropriate time. It will
4802 increase the hash table size if the there is twice as much
4803 entries in the table than the size of the table, and will
4804 decrease the size if there are twice as less entries than
4805 the size of the table.
4807 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4809 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4811 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4813 * silc_idcache_purge_by_context deletes the entry now by context
4814 as it is supposed to do. Affected file lib/silccore/idcache.c.
4816 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4817 client is not anymore valid (WHOWAS givens the info) and not
4818 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4820 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4822 * Removed the `data' and `data_len' arguments from the ID Cache
4823 interfaces and added `name' argument. ID Cache does not handle
4824 anymore the binary data only a names associated with given ID.
4826 * When hashing a Client ID with silc_hash_id the entire ID is
4827 not hashed anymore, instead only the hash of the Client ID is
4828 hashed. This way we can access the Client ID from the cache
4829 with Client ID but with the hash of the ID (which is a hash of
4830 the nickname) as well without any difference in performance.
4832 Added also silc_idcache_find_by_id_one_ext to do one on one
4833 searching when we have the actual ID. Added also function
4834 silc_hash_client_id_compare. The affected files are
4835 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4837 * When hashing the name associated with a ID it is always done
4838 in lowercase. This way we can access the cache without worrying
4839 about case-sensitivity, even though, for example nicknames are
4842 * Fixed a bug in server with channel message sending. It put
4843 wrong ID type as destination ID. The affected file
4844 silcd/packet_send.c.
4846 * silc_idcache_del_by_context now deletes from all hash tables
4847 by context. Affected file lib/silccore/idcache.c.
4849 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4851 * Changed the client library to use the new ID Cache interface.
4852 Changes around the source tree.
4854 * Added silc_hash_table_rehash_ext to rehash with specific
4855 hash function. Affected file lib/silcutil/silchashtable.[ch].
4857 * Added silc_hash_string_compare to compare two strings in the
4858 hash table. Affected file lib/silcutil/silcutil.[ch].
4860 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4862 * Added new function silc_idcache_del_by_context into the
4863 lib/silccore/idcache.[ch].
4865 * Changed the server's ID list routines to use the new ID Cache
4866 interface. Changes around the source tree.
4868 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4870 * Added silc_hash_table_del[_by_context]_ext functions in to the
4871 lib/silcutil/silchashtable.[ch].
4873 Removed silc_hash_table_find_all* routines and added new
4874 silc_hash_table_find_foreach to replace them.
4876 Added silc_hash_table_replace_ext function as extended
4877 replacing function. Separated the simple hash table interface
4878 from the extended hash table interface in the file
4879 lib/silcutil/silchashtable.h.
4881 * Fixed minor bugs and changed it to use some of the new
4882 hash table functions in lib/silccore/idcache.c
4884 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4886 * Added new function silc_hash_table_find_all to return all keys
4887 in the hash table by the specified key. As the hash table is
4888 collision resistant it also makes it possible to have several
4889 duplicate keys in the hash table. This function may be used to
4890 find all of the keys from the hash.
4892 Added user_context arguments to the SilcHashFunction,
4893 SilcHashCompare and SilcHashDestructor to deliver user specified
4896 Added new fuctions silc_hash_table_find[_all]_ext to do
4897 extended lookup with specified hash and compare functions and
4898 specified user contexts.
4900 Added new function silc_hash_table_add_ext to add the key
4901 with specified hash function and user context.
4903 Added new function silc_hash_table_foreach to traverse all
4904 entrys in the hash table. Added SilcHashForeach callback
4907 Added new function silc_hash_table_del_by_context to delete
4908 the entry only if the context associated with the key matches.
4910 Affected files are lib/silcutil/silchashtable.[ch].
4912 * Removed silc_hash_[server/client/channel]_id and added just
4913 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4914 silc_hash_id_compare to compare two ID's using as the hash table
4915 comparison function. Added also silc_hash_data to hash
4916 binary data and silc_hash_data_compare to compare it.
4918 * Removed silc_idlist_find_client_by_hash as it is not needed
4919 anymore. Affected file silcd/idlist.[ch].
4921 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4922 to use internally the SilcHashTable. The new ID Cache is a lot
4923 faster than the old one. Some of the ID Cache interface was also
4924 rewritten and obsolete and stupid functions were removed.
4926 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4928 * Added entry_count field to the SilcHashTable to keep the number
4929 of the entries in the table. Implemented the function
4930 silc_hash_table_rehash. Added new function
4931 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4933 Fixed a minor bug in silc_hash_table_free.
4935 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4936 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4937 into the lib/silcutil/silcutil.[ch].
4939 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4941 * Implemented a collision resistant hash table into the
4942 lib/silcutil/silchashtable[ch]. See the header and the source
4943 for the SilcHashTable API.
4945 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4947 * Merged dotconf version 1.0.2 into lib/dotconf.
4949 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4951 * Do not compile anything in lib/silcsim/* if the SIM support
4952 is not enabled. The tree should now compile without problems
4955 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4957 * Compiled the SILC under cygwin. Compiled and tested briefly
4958 without problems. More tests needed. The SIMs didn't compile
4961 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4963 * Fixed possible crash in silc_get_username in the
4964 lib/silcutil/silcutil.c.
4966 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4968 * Fixed a va_arg in silc/client_ops.c.
4970 * Oops, RC5 routines were named AES and caused some problems
4971 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4973 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4975 * Added new SilcIDIP structure into the lib/silccore/id.h and
4976 replaced the old `ip' fields from all SILC ID's to that type.
4977 This is a step towards IPv6 support.
4979 The silc_id_get_len takes now the ID as an extra argument.
4980 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4981 both IPv4 and IPv6 based ID's.
4983 The affected files are lib/silccore/id.[ch] and other files
4984 around the tree using these routines.
4986 * Removed the ID length arguments in server from various
4987 silc_server_send_notify_* routines -> they are not needed
4990 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4992 * Fixed memory leak in silc_encode_pem_file in the file
4993 lib/silcutil/silcutil.c.
4995 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4997 * Check minor version as well in the SKE. Affected files are
4998 silcd/protocol.c and lib/silcclient/protocol.c.
5000 * Added --identifier option to the server so that an identifier
5001 can be when creating the public key for the server. Affected
5002 file is silcd/silcd.c.
5004 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
5005 lib/silccrypt/silcpkcs.c.
5007 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5009 * Register default ciphers and stuff when using -C option with
5010 the server. Affected file sildc/silcd.c.
5012 * Put back the servers public key filename format, it is better
5013 than the new one. For now, the client keys are saved with the
5014 new filename format. The affected file silc/client_ops.c.
5016 * Implemented the Cipher API for the rest of the ciphers that
5017 did not implement it or implemented it the wrong way.
5019 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5021 * Register default ciphers and stuff when using the -S option
5022 in the client. Affected file silc/silc.c. Same also when
5023 creating new key pair with -C option.
5025 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5027 * Fixed the silc_verify_public_key client operation function to
5028 save the public keys differently. The fingerprint is now
5029 used as filename and not the hostname. This way also the
5030 client keys are saved uniquely and not with hostnames. The
5031 affected file is silc/client_ops.c.
5033 * Trimmed the silc_hash_fingerprint function to remove extra
5034 whitespaces from the end of the fingerprint. The affected
5035 file is lib/silccrypt/silchash.c.
5039 * Added silc_cipher_register_default function to register all
5040 default ciphers. It can be used when configuration files
5041 does not exist and the application does not want any specific
5042 ciphers in any specific order.
5044 The SilcDList is now used as silc_cipher_list dynamically
5045 allocated cipher list. Removed the static list all together
5046 and now all ciphers must be allocated to the dynamic list.
5047 The silc_cipher_alloc routine was changed to check only the
5050 All silc_cipher_* routines that used to return int returns
5053 The affected files lib/silccrypt/silccrypt.[ch].
5055 * The same thing was done to silc_hash_* as for silc_cipher_*
5056 routines. Affected files lib/silccrypt/silchash.[ch].
5058 * The same thing was done to silc_pkcs_* as for silc_cipher_*
5059 routines. Affected files lib/silccrypt/silcpkcs.[ch].
5060 Added also silc_pkcs_[un]register[_default] functions.
5061 Removed the data_context from the PKCS API.
5063 * Added silc_hmac_register_default function to register default
5064 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
5065 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
5066 to unregister all hmacs at once.
5068 * Register the default ciphers, hash functions, PKCSs and HMACs
5069 if client's configuration file does not exist. The affected
5072 * The client did not load the hash functions from the SIM
5073 modules at all. Added support for this. Affected file is
5074 silc/clientconfig.c.
5076 * When decoding public key with silc_pkcs_public_key_decode, check
5077 the supported algorithm only if PKCS are registered. Affected
5078 file lib/silccrypt/silcpkcs.c. The same was done with the
5079 silc_pkcs_private_key_decode.
5081 * Fixed the SILC List routines to keep the list always in order.
5082 It used to change the list's order when traversing the list but
5083 not it preserves the order. Affected file lib/trq/silclist.h.
5085 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5087 * Added the client library to use the SilcSocketConnection's
5088 reference counter (by silc_socket_dup) to prevent the bug that
5089 the socket object may be freed underneath async operation.
5091 * The name resolv library checking fixes in the configure.in.pre.
5094 * Created new version of the protocol drafts for future
5095 development. The -03 drafts are the ones that will be changed
5096 in the trunk now and the -02 will remain as they are.
5098 * Send list of CUMODE notifys to the router when announcing
5099 the channel users to the router. Affected file silcd/server.c.
5100 If the router receiving channel founder CUMODE for a channel
5101 that already has channel founder it will send CUMODE notify
5102 to the sender to remove the channel founder rights from the
5103 announced client. Affected file silcd/packet_receive.c.
5105 * The CUMODE notify may now use Server ID as well as the entity
5106 who changes the mode. Updated protocool specs.
5108 * Updated INSTALL and README files.
5110 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5112 * New web pages in the http://silc.pspt.fi. The pages was
5117 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5119 * Implemented the [DenyConnectin] config section in the server.
5120 Added silc_server_config_denied_conn to check whether incoming
5121 connection is denied. Affected file silcd/serverconfig.[ch].
5123 * Do not check the ports when checking the incoming configuration
5124 data if the port is 0, meaning any. Affected file is
5125 silcd/serverconfig.c.
5127 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5129 * Fixed buffer overflow in silc_string_compare in the file
5130 lib/silcutil/silcutil.c.
5132 * Fixed double free in silc_server_command_leave in the file
5135 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5137 * Fixed the version checking in the server. Affected file is
5140 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5142 * Fixed the configuration data fetching when accepting new
5143 connections in the server. Affected file silcd/server.c.
5145 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5147 * Added `sender_entry' argument to the function
5148 silc_server_packet_relay_to_channel so that we can check
5149 whether some destination actually belongs to the same route
5150 the sender belongs (ie, we must not resend the packet to the
5151 sender). Affected file silcd/packet_send.[ch].
5153 * Added `servername' field to the SilcClientEntry in the server
5154 to hold the name of the server where client is from. Affected
5155 file is silcd/idlist.h.
5157 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5159 * Moved the channel message encrypting in the router betwen
5160 router connections from silc_server_channel_message to the
5161 silc_server_packet_relay_to_channel since we want to check
5162 whether we have anybody channel before encrypting anything.
5163 Affected files silcd/packet_[receive/send].c.
5165 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5167 * Fixed the [AdminConnection] server config section to support
5168 multiple entries. Affected file silcd/serverconfig.c.
5170 * Added support into the server to check the validity of the
5171 incoming connection before executing any KE or authentication
5174 * The connection configuration is now saved to the KE and
5175 connection auth protocol contexts and not fetched anymore in
5176 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
5178 * The local hosts listenning address and port is also resolved
5179 now when starting the server. We want to have the socket object
5180 to include the real address and port for the listener. Added
5181 new function silc_net_check_local_by_sock into the files
5182 lib/silcutil/silcnet.[ch].
5184 * Fixed a broadcast bug in server -> do not broadcast if we
5187 * Fixed a routing bug. Do not route broadcast packets ever.
5188 Broadcast packets must be processed always and not routed since
5189 they may be destined to some other host than yourself and thus
5190 would get routed without no good reason. Affected file is
5193 * Added function silc_server_config_is_primary_route to check
5194 whether primary router connection has been configured (a router
5195 configuration that we are initiating). If there is not, we
5196 will assume that there is only two routers in the SILC network
5197 and we will use the incoming router connection as our primary
5198 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
5200 * Changed the order of the broadcasting. Broadcast _after_ the
5201 packet has been processed not before. Affected file is
5204 * Fixed a [ClientConnection] parsing bug. The port was never
5205 parsed correctly thus resulting to port 0. Affected file
5206 silcd/serverconfig.c.
5208 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
5209 argument and did not set the broadcast packet flag. Affected
5210 file silcd/packet_send.c. Fixed same bug in the function
5211 silc_server_send_notify as well.
5213 * If we receive NEW_ID packet for our own ID in the server, ignore
5216 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5220 * Removed the nickname from the Private Message Payload.
5221 Updated the code and the protocol specs.
5223 * Updated protocol specs for submitting to the IETF.
5225 * Tweaked the Random Number Generator a bit. Affected file
5226 lib/silccrypt/silcrng.c. Exported a new function
5227 silc_rng_[global]_add_noise which can be used to add more
5230 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5232 * Do not parse packets with different timeout when protocol
5233 is active -> may cause problem with rekey. Affected file
5236 * When server receives signoff notify it must not create
5237 new channel key if the client is on any channels since the
5238 sender of the signoff notify will create it.
5240 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5242 * Added printing of error messages during SKE protocol from the
5243 failure packet sent by server during SKE. Affected file
5246 * Removed the client's failure_callback handling with timeout
5247 and handle it immediately when received.
5249 * The SKE library returned wrong type in SUCCESS and FAILURE
5250 packets. They must be 32 bit MSB not 16 bit MSB.
5252 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5254 * Ok, rewrote the logic of the re-key and now it seems to work.
5255 I tested it on high traffic with frequent re-keys without
5256 problems. Added hmac_receive (and renamed hmac to hmac_send)
5257 in SilcClientConnection in lib/silcclient/client.h and
5258 in SilcIDListData in silcd/idlist.h. Also, removed the
5259 SilcPacketParserContext's cipher and hmac fields as they are
5260 not needed anymore and actually caused some problems when
5261 the ciphers and hmac's changed underneath the packet parser.
5263 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5265 * If re-key protocol is active then process the incoming packets
5266 synchronously since we must assure that icoming packets encrypted
5267 with the old key is processed before the new keys is set to
5268 use. This is true other packets than for REKEY packets.
5269 Affected file silcd/server.c. The same was done to client library
5270 as well, affected file lib/silcclient/client.c.
5272 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5274 * Fixed bug in client and server to accept the force send if
5275 the packet is send from silc_[server/client]_packet_process
5276 function. Otherwise the packets are never delivered, oops.
5278 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5280 * Disable force sending of packets when REKEY protocol is active.
5281 We must assure that no packet is sent directly when rekey is
5282 performed. All packets must be sent through packet queue.
5283 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
5284 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
5285 function is silc_[server/client]_packet_send_real to check
5288 * Replaced the SIM paths from example config files to
5289 /usr/local/modules. Also, make install creates now
5290 /usr/local/silc/logs directory to hold all the SILC server
5293 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5295 * Made the configure.in.pre work on Solaris. Patch by salo.
5297 * Made all ciphers compatible with non-x86 machines. Defined
5298 CBC mode macros into lib/silccrypt/ciphers_def.h.
5300 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5302 * Fixed the make install.
5304 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5306 * When MAC computation fails the silc_packet_decrypt returned 0
5307 even though it was supposed to return -1. Fixed this. The
5308 affected file is lib/silccore/silcpacket.c.
5310 * Do not replace the config files in /etc/silc (in make install)
5311 if they already exist. Affected file ./Makefile.am.
5313 * Do not send re-key packets immediately but through packet queue.
5314 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
5316 * Changed silc_net_check_host_by_sock to return FALSE if the
5317 IP/DNS could not be resolved. Though, it returns the IP address
5318 now even if it could not resolve it (but returns also FALSE).
5319 Affected file lib/silcutil/silcnet.[ch].
5321 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5323 * Added silc_pkcs_decode_identifier to decode the public key's
5324 identifier. Affected file lib/silccrypt/silpkcs.[ch].
5325 Added also silc_pkcs_free_identifier. Added also new context
5326 SilcPublicKeyIdentifier.
5328 * Added -S option to the silc client. It is used to dump the
5329 contents of the specified public key file.
5331 * Changed the PKCS api to return the public key length when
5332 setting the public key.
5334 * Fixed a fatal bug in the public and private key file loading.
5335 Affected file lib/silccrypt/silcpkcs.c.
5337 * Execute the packet parsing for client with zero (0) timeout
5338 if the protocol is active. Affected file silcd/server.c.
5340 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5342 * Made the key generation options to the silcd program. Added
5343 -C option, equivalent to client's option.
5345 * Added new [ServerKeys] config section to the server. It
5346 configures the server's public and private key.
5348 * Defined generic Public Key Payload into the protocol
5349 specification to send specific type of public keys and
5352 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
5353 public key or certificate.
5355 * Implemented the GETKEY command to the server and to the
5356 client library and on user interface.
5358 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5360 * Made preliminary `make install' work.
5362 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5364 * Added SilcServerRekey context into silcd/idlist.h.
5366 * Added the PFS support as defined in the specification to the
5367 SKE protocol. Affected files lib/silcske/*.c.
5369 * Added `ske_group' field to the SilcServerRekey context to hold
5370 the number of the SKE group that is used with PFS in re-key.
5371 Affected file silcd/idlist.h.
5373 * Added PFS re-key support to the server. Affected file is
5376 * Added silc_protocol_cancel to cancel execution of the next
5377 state of the protocol. Affected file is
5378 lib/silccore/silcprotocol.[ch].
5380 * Added the re-key support with and without PFS to the client
5381 library. Re-key is performed once in an hour, by default.
5383 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
5384 Added silc_client_rekey_callback and silc_client_rekey_final.
5385 Affected files are lib/silcclient/protocol.[ch] and
5386 lib/silcclient/client.[ch].
5388 * Removed the `hmac_key' and `hmac_key_len' fields from the
5389 SilcClientConnection structure; not needed. Affected file is
5390 lib/silcclient/client.h.
5394 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5396 * Do not ask whether user wants to use the negotiated private key
5397 for private messages, just use it. Affected file is
5398 silc/local_command.c.
5400 * Added `send_enc_key' and `enc_key_len' fields to the
5401 SilcIDListData structure since they are needed in the re-key
5402 phase. Affected file is silcd/idlist.[ch].
5404 * Implemented the simple re-key protocol into the server.
5405 Affected files silcd/server.c and silcd/protocol.[ch]. The
5406 re-key will be performed once in an hour, by default.
5408 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
5409 Added silc_server_rekey, silc_server_rekey_callback and
5410 silc_server_rekey_final.
5412 * Removed Tunneled flag from the protocol. Updated the code
5413 and the specifications.
5415 * Adde `pfs' field to the SilcIDListData to indicate whether
5416 the PFS is to be performed in the re-key. Affected file is
5419 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5421 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
5422 int64 of at least the xintXX size. If void * is less that 4
5423 bytes uint32 * will be used. Defined bool as boolean.
5425 * Changed _ALL_ unsigned long and unsigned int to uint32,
5426 unsgined short to uint16 in the source tree.
5428 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
5429 not handle clients that has entry->data.registered == FALSE.
5430 They are not in the network anymore. Affected file is
5433 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5435 * Implemented the sending of the SERVER_SIGNOFF notify in the
5436 server. Affected file is silcd/server.c.
5438 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
5439 Added also silc_notify_payload_encode_args into the
5440 lib/silccore/silcnotify.[ch].
5442 * Implemented ther SERVER_SIGNOFF notify handling in the server.
5443 Affected file silcd/packet_receive.c.
5445 * Implemented the SERVER_SIGNOFF notify handling in the client
5446 library. Affected file lib/silcclient/client_notify.c. Also,
5447 implemnted the printing of the SERVER_SIGNOFF info to the
5448 application. Affected file silc/client_ops.c.
5450 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
5451 if the deleting was successful. Affected file silcd/idlist.[ch].
5453 * Added support for public key authentication in the connection
5454 authentication protocol in the client library. Affected file
5455 lib/silcclient/protocol.c.
5457 * Changed the server's silc_idlist_get_clients_by_* interface
5458 to support already allocated array so that new entries may be
5459 added to pre-allocated array. Affected file silcd/idlist.[ch].
5460 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
5461 and command replies.
5463 * All command reply functions in the server now calls the
5464 pending command callback even if error occured. This way the
5465 error will be delivered to the client as well. Affected files
5466 silcd/command.c and silcd/command_reply.c.
5468 * Fixed INFO command to return local server's info if no server
5469 was provided. Affected file lib/silcclient/command.c.
5471 * Removed RESTART command for good. Updated the code and the
5474 * Rewrote parts of the task system. It is a bit simpler now.
5475 Removed unsued task priorities. The affected files are
5476 lib/silcutil/silctask.[ch].
5478 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5480 * Moved the USERS printing from the library to the application.
5481 Affected files lib/silcclient/command.c and silc/client_ops.c.
5483 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5487 * Added channel key re-key support. The re-key is perfomed
5488 only by the router and is done once in an hour. Added `rekey'
5489 field to the SilcChannelEntry in the server. Affected files
5490 silcd/server.c and silcd/idlist.h.
5492 * Added silc_task_unregister_by_context into the file
5493 lib/silcutil/silctask.[ch].
5495 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5497 * Added SILC_UMODE_GONE mode to indicate when the client is not
5498 present in the SILC network. Added also support to the local
5499 command AWAY that will set this mode. Added support of showing
5500 "xxx is gone" in WHOIS command. The USERS command shows the
5501 gone status as well.
5503 * Fixed setting server and router operator privileges in the
5504 server's UMODE command. Affected file silcd/command.c.
5506 * Merged the SKE KE1 and KE2 payloads into one payload. The
5507 new KE payload is equivalent to the old KE2 payload.
5509 Cleaned up the SKE Start Payload parsing. It now uses the
5510 simple buffer unformatting to do the parsing. A lot faster
5513 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
5514 to the SKE that is used to indicate whether both of the SKE
5515 parties should perform authentication. By default only the
5516 responder performs authentication. By setting this flag also
5517 the initiator must do authentication. By default it is unset
5518 since in normal SKE case, client to server connection, only
5519 the responder should do authentication. When doing SKE between
5520 two clients both should perform authentication. Updated the
5521 code and the protocol specs.
5523 * A little fix to IDENTIFY command in the server. Search the
5524 client first by hash not nickname. Affected file is
5527 * Fixed the silc_client_close_connection to support closing
5528 the client to client connections wihtout deleting too much
5529 data. Affected file lib/silcclient/client.c.
5531 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
5532 are received if protocol used to be active but is not anymore
5533 the application would crash due to NULL pointer dereference.
5534 Affected files silcd/server.c and lib/silcclient/client.c.
5536 * Added `hash' field to the SilcClientConnection to include
5537 the hash function negotiated in the SKE protocol.
5539 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
5540 to set the channel founder authentication data. A client can
5541 claim the founder rights later by providing the authentication
5542 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
5543 This way the channel founder can regain the channel founder
5544 privileges even it is left the channel. This works only on
5545 local server and the client must be connected to the same
5546 server to be able to regain the founder rights. Updated the
5547 protocol specs accordingly.
5549 Added support to the CMODE command in the client to set the
5550 founder auth data. Read the README to see how to set it.
5552 Added support to the CUMODE command to claim the founder
5553 rights. Read the README to see how to do it.
5555 Added support for the founder authentication to the Channel
5556 Entry in the server. Affected file silcd/idlist.h.
5558 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
5559 server's CMODE command. Affected file silcd/command.c.
5561 * Added the following new functions into lib/silccore/silcauth.[ch]:
5562 silc_auth_get_method and silc_auth_get_data.
5564 * The server now saves the remote hosts public key to the
5565 SilcIDListData pointer. Affected file silcd/protocol.c.
5567 * The normal server now does not remove the channel entry from
5568 the cache if the founder authentication data is set. It used
5569 to remove it if the founder was the last one on the channel on
5570 the server and left the channel. The auth data is saved and
5571 if the channel is re-joined later the old entry is used with
5572 the old auth data. Affected files silcd/command_reply.c and
5575 * Removed the `pkcs' field from the SilcIDListData structure
5576 in the server; it is not used. Affected file silcd/idlist.h.
5578 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5580 * Fixed packet processing on slow links. Partial packets were
5581 never re-processed because the incoming data buffer was cleared
5582 by the application. Application must not directly clear the
5583 sock->inbuf, the packet processing routines handle it. Fixed
5584 this in client library and in server.
5586 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5588 * Fixed the WHOIS and IDENTIFY send reply function to really
5589 check whether to send list or just one entry. Affected file
5592 * Cleaned up the LEAVE command's channel key distribution. The
5593 affected file silcd/command.c.
5595 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
5596 can enforce the channel mode as well. In that case the ID
5597 includes the ID of the server. The code now enforces the
5598 mode change if the router have different mode than the server.
5600 * The notify client operation with CMODE_CHANGE notify can now
5601 return NULL client_entry pointer if the CMODE was not changed
5602 by client. Application must check for this.
5604 * Added <Server ID> argument to INFO command to support server
5605 info fetching by Server ID.
5607 * Added silc_server_announce_get_channel_users to get assembled
5608 packets of channel users of the specified channel. Affected
5609 file silcd/server.[ch].
5611 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
5612 was freed underneath the ID Cache.
5614 * Re-announce clients when the server received CHANNEL_CHANGE
5615 notify from the router. Affected file silcd/packet_send.c.
5617 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5619 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
5620 crashed since it did not handle the fact that there is no cipher
5621 called "3" and didn't check the error condition. Now fixed.
5623 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
5624 flag. It can be used to send message requests.
5626 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5628 * Implemented the RESTART command in the client.
5630 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
5631 notice type messages. Added notice printing to the user
5634 * The channel keys are not re-generated if the channel's mode
5635 is PRIVKEY, ie private key on the channel exists. Affected
5636 files silcd/server.c and silcd/command.c.
5638 * Fixed a little bug in channel message delivery when channel
5639 private keys are set in the server. Affected file is
5640 silcd/packet_send.c.
5642 * Changed the setting on channel->on_channel = TRUE from the
5643 silc_client_save_channel_key to the JOIN command reply. The
5644 key payload is not received if the private channel key is set.
5645 Affected file lib/silcclient/command_reply.c and the
5646 lib/silcclient/client_channel.c.
5648 * When the CMODE_CHANGE notify is sent and the channel private
5649 key mode is removed the channel key must be re-generated in
5650 other cells as well. Added this support for the router in the
5651 silcd/packet_receive.c.
5653 * Added new local command NOTICE to send notice message on
5654 channel. Affected file silc/local_command.[ch].
5656 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5658 * Added new local command ME to the client. It is used to send
5659 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
5660 some action. Affected file silc/local_command.[ch].
5662 * Changed channel_message and private_message client operations
5663 to deliver the message flags to the application. Added also
5664 the `flags' arguments to the silc_client_send_channel_message
5665 and silc_client_send_private_message functions. Affected file
5668 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5670 * Redefined the Private Message Payload to support private message
5671 keys and to support the new private message flags. Updated
5672 the protocol specs. Flags makes it possible to have for example
5673 CTCP style messages.
5675 * Added new type SilcPrivateMessagePayload and defined an API
5676 for it in the lib/silcclient/silcprivate.[ch].
5678 * Tested private message private keys successfully. Tested the
5679 private message key set, unset and list commands with the new
5682 * Redefined the Channel Message Payload to include the channel
5683 message flags (equal with private message flags) to support
5684 for example CTCP style messages.
5686 * Defined some of the message (for channel and private message)
5687 flags. Updated the protocol specs and added the flags to the
5688 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5690 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5692 * Added SilcKeyAgreementStatus type to the key agreement routines
5693 to indicate the current status and error if one occured.
5694 The status types are defined in the lib/silcclient/silcapi.h.
5696 * Added new local command KEY that is used to set and unset private
5697 keys for channels, set and unset private keys for private messages
5698 with remote clients and to send key agreement requests and
5699 negotiate the key agreement protocol with remote client. The
5700 key agreement is supported only to negotiate private message keys,
5701 it currently cannot be used to negotiate private keys for channels,
5702 as it is not convenient for that purpose.
5704 * Fixed a minor pending callback setting bug in the function
5705 silc_client_get_client_by_id_resolve, now the function works.
5706 Affected file lib/silcclient/idlist.c.
5708 * Added function silc_net_get_local_port to get local bound
5709 port by socket. Added to lib/silcutil/silcnet.[ch].
5711 * Added `sockets' and `sockets_count' fields to the SilcClient
5712 object. They hold the sockets of the listenning sockets in
5713 the client. Listenning sockets may be for example the key
5714 agreement server. Affected file lib/silcclient/client.[ch].
5715 Added functions the silc_client_add_socket and the
5716 silc_client_del_socket. They are exported to the application
5719 * Added ~./silc/clientkeys to support other client's public keys.
5721 * Renamed verify_server_key client operation to verify_public_key
5722 and added one argument to indicate the type of the connection
5723 (server, client etc.).
5725 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5727 * Added silc_server_connection_auth_request to handle the
5728 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5729 silcd/packet_receive.[ch].
5731 * Added silc_server_send_connection_auth_request into the
5732 silcd/packet_send.c to send the connection auth request packet.
5734 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5737 * Fixed the public key authentication in responder side in the
5738 server. The `auth_data' pointer includes the SilcPublicKey
5739 not the path to the public key. Affected file silcd/protocol.c.
5741 * Implemented the public key authentication in the initiator side
5742 in the server. Affected file silcd/protocol.c.
5744 * Removed the [RedirectClient] config section from the server
5745 configuration. Is not needed and I don't want to implement it.
5747 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5749 * Cleaned up the CMODE command in the server. It now works
5750 correctly and supports all the modes defined in the protocol.
5751 Affected file is silcd/command.c.
5753 * Added `hmac_name' field to the SilcChannelEntry in the server
5754 to hold the default HMAC of the channel. It can be set when
5755 creating the channel (with JOIN command). Affected files
5758 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5759 type to indicate the change of the current cipher and hmac
5760 on the channel. Client can safely ignore the <cipher> argument
5761 (if it chooses to do so) since the CHANNEL_KEY packet will
5762 force the channel key change anyway. The <hmac> argument is
5763 important since the client is responsible of setting the new
5764 HMAC and the hmac key into use.
5766 * Fixed the CMODE command in the client library as well.
5768 * Tested CMODE command in router environment successfully.
5770 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5772 * Show the version of the remote client (or server) when connecting
5773 to the server. It is logged to the log file. Affected file
5774 is silcd/protocol.c.
5776 * Fixed the KILLED notify handling in the client library. The
5777 client must be removed from all channels when receiving the
5780 Also, do not remove the client entry when giving the KILL
5781 command but when the KILLED notify is received.
5783 * Removed silc_idlist_find_client_by_nickname from the server.
5784 Not needed anymore. Affected files silcd/idlist.[ch].
5786 * Implemented the CHANNEL_CHANGE notify type handling to the
5787 server. Affected file silcd/server.c.
5791 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

5805 * Added function silc_server_get_client_resolve to find the
5806 client entry by ID from all ID lists and then resolve it
5807 (using WHOIS) if it cannot be found. Affected file is
5810 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5812 * Implemented the BAN command to the client library.
5814 * The JOIN command in the server now checks the invite list
5817 * Changed the silc_command_reply_payload_encode_va and the
5818 silc_command_payload_encode_va to support that if argument is
5819 NULL it ignores and checks the next argument. Affected file
5820 lib/silccore/silccommand.c.
5822 * Added silc_server_send_notify_ban to send the BAN notify
5823 type between routers.
5825 * Chaned the silc_notify_payload_encode to support that if
5826 argument is NULL it ignores and checks the next argument.
5827 Affected file lib/silccore/silcnotify.c.
5829 * Tested ban lists in router environment successfully.
5831 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5833 * Implemented BAN command to the server, in silcd/command.[ch].
5835 * Removed the BAN and INVITE_LIST modes from the CMODE command
5838 * Added function silc_string_match to regex match two strings.
5839 Affected files lib/silcutil/silcutil.[ch].
5841 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5843 * Redefined parts of the SilcChannelEntry in the server to support
5844 the new ban and invite lists.
5846 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5848 * Redefined the INVITE command. The same command can be used to
5849 invite individuals to the channel but also to manage the invite
5850 list of the channel (to add to and remove from the invite list).
5851 Updated the protocol specs.
5853 * Added new command SILC_COMMAND_BAN that can be used to manage
5854 the ban list of the channel. Updated the protocol specs.
5856 * Removed the channel modes: the SILC_CMODE_BAN and the
5857 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5858 in the CMODE command. The equivalent features are now available
5859 using INVITE and BAN commands. Updated the protocol specs.
5861 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5862 in the network about change in the current ban list. The notify
5863 type is not used by the client.
5865 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5866 support the invite lists.
5868 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5870 * Added new function silc_string_regexify that converts string
5871 including wildcard characters into regex string that can
5872 be used by the GNU regex library. Added into the file
5873 lib/silcutil/silcutil.[ch].
5875 Added silc_string_regex_combine to combine to regex strings
5876 into one so that they can be used as one regex string by
5877 the GNU regex library. Added into the file
5878 lib/silcutil/silcutil.[ch].
5880 Added silc_string_regex_match to match two strings. It returns
5881 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5883 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5885 * Imported GNU regex to the soruce tree into lib/contrib.
5886 Fixed some compiler warning from the regex.c.
5888 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5890 * Fixed MOTD command in the server to work in router environment.
5892 * Fixed the MOTD command in the client library to support
5893 the server argument in the command.
5895 * Added `nickname_len' argument to the silc_idlist_add_client
5896 in the server, as the `nickname' argument may be binary data
5899 * Added silc_idlist_get_channels to return all channels from
5902 * Implemented LIST command to the server. Affected file is
5905 * Implemented the LIST command to the client library and on the
5908 * Added [<user count>] argument to the LIST command reply.
5909 With private channels the user count is not shown.
5911 * Updated TODO and README.
5913 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5915 * The client entry's data.registered must be TRUE even with
5916 global client entry on global client list. The data.registered
5917 is used to check whether the client is anymore in the network,
5918 for example with WHOWAS command so it must be valid.
5920 * Fixed the WHOWAS command in the server. It now actually works
5921 in router environment. Added function into silcd/command_reply.c
5922 silc_server_command_reply_whowas_save.
5924 * Added silc_idlist_purge function to the silcd/idlist.c
5925 to periodically purge the ID Cache.
5927 * Fixed INFO command in the server. It works now in router
5928 environment. Added <server name> argument to the INFO command
5929 reply. Updated the protocol specs.
5931 * Fixed minor bug in silc_idcache_purge to not purge if the
5932 expire value is zero.
5934 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5935 they were buggy because of the WHOWAS information.
5937 * Fixed local command MSG to handle the async resolving of
5938 the remote client properly. It used to fail the first MSG.
5939 Affected file silc/local_command.c.
5941 * Added `data_len' field to SilcIDCache context.
5943 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5945 * Update TODO. Todo in commands in the server.
5947 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5949 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5950 used by routers as broadcast packet to inform other routers
5951 about the changed user mode.
5953 Implemented the notify handling in the server. Affected file is
5954 silcd/packet_receive.c. Added the function
5955 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5957 * Added new generic Channel Payload and deprecated the New Channel
5958 Payload. The New Channel Payload is now the generic Channel
5961 * Added new argument `mode' to the silc_server_send_new_channel
5962 as it is required in the Channel Payload now.
5964 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5965 and created a new and real SilChannelPayload to represent the
5966 new generic Channel Payload. Implemented the encode/decode
5967 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5969 * Added silc_server_get_client_channel_list to return the list
5970 of channels the client has joined for WHOIS command reply.
5971 Affected file silcd/server.[ch].
5973 * Implemented the channel list sending in the WHOIS command reply
5974 in server and in the client.
5976 Implemented the channel list displaying on the user interface
5977 as well. Affected file silc/client_ops.c.
5979 * Added silc_channel_payload_parse_list to parse list of Channel
5980 Payloads. It returns SilcDList list of SilcChannelPayloads.
5981 Client for example can use this function to parse the list of
5982 channels it receives in the WHOIS command reply. The caller
5983 must free the list by calling silc_channel_payload_list_free.
5984 Affected files lib/silccore/silcchannel.[ch].
5986 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5988 * Added one new argument <user mode> to the WHOIS command reply
5989 to return the mode of the user in SILC. Updated the protocol
5992 Implemented it to the server and client.
5994 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5996 * Fixed the mode printing on the user interface on joining.
5997 Affected file silc/client_ops.c.
5999 * Implemented the UMODE command and user modes in general to the
6000 client library and to the user interface.
6002 * Implemented the UMODE command to the server.
6004 * The server now sends UNKNOWN_COMMAND error status if client sends
6005 unknown command. Affected file silcd/command.c.
6007 * All server commands now handle the command identifier the right
6008 way when sending the command reply to the client. The client can
6009 use to identify the command replies with the identifier.
6011 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6013 * Added silc_server_get_client_route to resolve the route to
6014 the client indicated by the client ID. Affected file is
6017 * Added silc_server_relay_packet as general function to relay
6018 packet to arbitrary destination. This deprecates functions
6019 like _send_private_message_key, _relay_notify etc. Affected
6020 file is silcd/packet_send.[ch].
6022 Removed silc_server_send_key_agreement,
6023 silc_server_send_private_message_key and
6024 silc_server_packet_relay_notify functions from the file
6025 silcd/packet_send.[ch].
6029 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
6030 server. Affected file silcd/packet_receive.[ch].
6032 * Implemented the KILL command to the client. Implemented the
6033 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
6034 Affected files lib/silcclient/command[_reply].c and
6035 lib/silcclient/client_notify.c. Implemented the KILL notify
6036 printing in the user inteface.
6038 * Fixed a lot silc_parse_nick memory leaks from the client
6039 library in the file lib/silcclient/command.c.
6041 * Changed the silc_server_send_notify_on_channels's `sender'
6042 argument from SilcSocketConnection to SilcClientEntry to
6043 check the sender as entry and not as connection object and not
6044 to send to the client provided as argument. The affected file
6045 is silcd/packet_send.[ch].
6047 * The notify packets that are destined directly to the client used
6048 to not to be processed by the server. Now changed that and the
6049 server processes all notify packets. After relaying the packet
6050 to the client the notify packet is processed in the server.
6052 * The silc_server_free_client_data now checks whether there is
6053 pending outgoing traffic for the client and purges the data to
6054 the network before removing the client entry.
6056 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6058 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
6059 an client is killed from the SILC Network. Updated the protocol
6062 Added new function silc_server_send_notify_killed to the
6063 silcd/packet_send.[ch].
6065 * Added function silc_server_packet_relay_notify to relay notify
6066 packets that are destined directly to a client. In this case
6067 the server does not process the notify packets but merely relays
6068 it to the client. Affected file silcd/packet_send.[ch].
6070 Added also silc_server_packet_process_relay_notify to check
6071 whereto relay the notify. Affected file is
6072 silcd/packet_receive.[ch].
6074 * Implemented the KILL command to the server.
6078 * Added the backup schema desgined last fall to the protocol
6079 specs for everyone to see. The specification is in the
6080 *-spec-xx.txt draft and the packet type definitions for the
6081 backup routers is in *-pp-xx.txt draft. Thusly, added also
6082 new packet type SILC_PACKET_CELL_ROUTERS.
6084 * A big security problem in the implementation discovered. The
6085 signoff of an client did not cause new channel key generation
6086 which it of course should've done. The channel keys must be
6087 always re-generated when client leaves (or signoffs) the channel.
6088 The silc_server_remove_from_channels funtion now handles
6089 the channel key re-generation.
6091 * Added `sender' argument to the silc_server_send_notify_on_channels
6092 to not to send the client provided as argument. Affected file
6093 silcd/packet_send.[ch].
6095 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6097 * Implemented OPER and SILCOPER commands into the server and
6100 * Added silc_auth_verify and silc_auth_verify_data to verify
6101 the authentication directly from the authentication payload.
6102 It supports verifying both passphrase and public key based
6103 authentication. Affected file lib/silccore/silcauth.[ch].
6105 * Added `hash' field to the SilcIDListData structure. It is the
6106 hash negotiated in the SKE protocol. Affected file is
6109 * Slight redesigning of the SilcAuthPayload handling routines.
6110 Do not send SilcPKCS but SilcPublicKey as argument.
6112 * Implemented the public key authentication support to the
6113 serverconfig. The public key is loaded from the provided path
6114 and saved as authentication data to void * pointer. Thus,
6115 changed the unsigned char *auth_data to void *auth_data;
6117 * Fixed SHUTDOWN command to send the reply before the server
6118 is shutdown. :) Affected file silcd/command.c.
6120 * Fixed fatal bug in CONNECT command. The hostname was invalid
6121 memory and server crashed. Affected file silcd/command.c.
6123 * Fixed fatal bug in CLOSE command. The server_entry became
6124 invalid but was referenced later in the command. Affected file
6127 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6129 * Fixed fatal bug in failure packet handling. Server ignored
6130 the failure and thus crashed when it came.
6134 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6136 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
6137 that the command may be executed only once in (about) 2 seconds.
6138 The old SILC_CF_LAG flag is same but allows command bursts up
6139 to five before limiting.
6141 Added the support for CF_LAG and CF_LAG_STRICT flags to the
6142 server code. Various commands now includes the CF_LAG_STRICT
6143 flag to disallow any kind of miss-use of the command.
6145 * Fixed the silc_buffer_unformat to not to allocate any data
6146 if the length of the data is zero. It used to allocate the
6147 length + 1. Affected file lib/silcutil/silcbuffmt.c.
6149 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6151 * Changed the format of AdminConnection configuration section
6152 in the server. Added username of the admin to the format.
6153 Affected files silcd/serverconfig.[ch].
6155 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
6156 to return admin configuration data by host, username and/or
6159 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6161 * Implemented WHOWAS command to the server. Added the functions:
6163 silc_server_command_whowas_parse,
6164 silc_server_command_whowas_send_reply,
6165 silc_server_command_whowas_from_client and
6166 silc_server_command_whowas_from_server
6168 * Added <Client ID> argument to the WHOWAS command reply. Updated
6169 the protocol specs accordingly.
6171 * Implemented WHOWAS command and command_reply to the client
6174 Implemented the WHOWAS printing on the user interface.
6176 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6178 * Added new argument to the WHOWAS command reply, the real name.
6179 It is an optional argument. Updated the protocol specs.
6181 * Added SilcIDCacheDestructor callback that is registered when
6182 the SilcIDCache is allocated. The callback is called when
6183 an cache entry in the ID Cache expires, or is purged from the
6184 cache. Added into lib/silccore/idcache.[ch].
6186 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
6187 to destruct the client entries when the cache entry expires.
6188 Other ID Cache's in server and in the client library ignores
6191 * If the ID Cache entry's `expire' field is zero then the entry
6192 never expires. Added boolean `expire' argument to the
6193 silc_idcache_add function in the lib/silccore/idcache.[ch].
6194 If it is TRUE the default expiry value is used.
6196 * Added silc_server_free_client_data_timeout that is registered
6197 when client disconnects. By default for 5 minutes we preserve
6198 the client entry for history - for WHOWAS command.
6200 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6202 * Added support to the server to enforce that commands are not
6203 executed more than once in 2 seconds. If server receives
6204 commands from client more frequently, timeout is registered
6205 to process the commands. Affected file silcd/command.c.
6206 Added new function silc_server_command_process_timeout.
6208 * Changed NICK_NOTIFY handling in client library to check that
6209 if the client's nickname was changed, so there is no need to
6210 resolve anything from the server.
6212 * Removed error printing from the WHOIS and IDENTIFY commands.
6213 If error occurs then it is ignored silently in the client library.
6214 The application, however, may map the received error to
6215 human readable error string. The application currently maps
6216 the NO_SUCH_NICKNAME error to string.
6218 * Made the command status message public to the application. Moved
6219 them from lib/silcclient/command_reply.c to
6220 lib/silcclient/command_reply.h. The application can map the
6221 received command status to the string with the
6222 silc_client_command_status_message function.
6224 * Added check to the server to check that client's ID is same
6225 as the Source ID in the packet the client sent. They must
6228 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6230 * Added dist-bzip hook to the Makefile.am to make bzip2
6231 compressed distributions.
6233 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6235 * Server now enforces the maximum length for the nickname and
6236 the channel as protocol specification dictates. 128 bytes for
6237 nickname and 256 bytes for channel name.
6239 * Moved the WHOIS printing to the application. The client libary
6240 does not print out the WHOIS information anymore, the application
6241 must do it. Renamed silc_client_command_reply_whois_print to
6242 the silc_client_command_reply_whois_save.
6244 The client's idle time is also sent to the application now, and
6245 the idle is shown on screen.
6247 * Added silc_client_command_reply_identify_save to save the
6248 received IDENTIFY entries.
6250 * Do not check for channel private keys in message sending and
6251 reception if the channel does not have the PRIVKEY mode set.
6252 Affected file lib/silclient/client_channel.c.
6254 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6256 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
6257 just surfaced after chaning the JOIN procedure.
6259 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6261 * Added silc_client_get_clients_by_list to get client entries
6262 from Client ID list, that is returned for example by JOIN
6263 and USERS command replies. The application should use this
6264 function for example when JOIN command reply is received to
6265 resolve the clients already on the channel (library does not
6266 do that anymore as USERS command reply is not used in the JOIN
6267 procedure anymore). Affected files lib/silcclient/silcapi.h and
6268 lib/silcclient/idlist.c.
6270 * JOIN command reply and USERS command reply returns now SilcBuffer
6271 pointers instead of unsigned char pointers when returning
6272 the client list and mode list.
6274 * Added <Client ID> argument to the JOIN command reply, mainly
6275 for the server to identify for which client the command was
6276 originally sent. Updated protocol specs accordingly.
6278 * Added SilcDlist private_key pointer to the SilcChannelEntry
6279 in the client to support the channel private keys. Affected
6280 file is lib/silcclient/idlist.h.
6282 * Added SilcChannelPrivateKey argument to the function
6283 silc_client_send_channel_message so that application can choose
6284 to use specific private ke if it wants to. If it is not provided,
6285 the normal channel key is used, unless private keys are set.
6286 In this case the first (key that was added first) is used
6287 as the encryption key.
6289 * Implemented the support for channel private key handling.
6290 Implemented the following functions:
6292 silc_client_add_channel_private_key,
6293 silc_client_del_channel_private_keys,
6294 silc_client_del_channel_private_key,
6295 silc_client_list_channel_private_keys and
6296 silc_client_free_channel_private_keys
6298 Affected file lib/silcclient/client_channel.c.
6300 * Added the support for the private keys in the channel message
6301 sending and encryption and in the message reception and
6302 decryption. Affected funtions are
6303 silc_client_send_channel_message and silc_client_channel_message.
6305 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6307 * Added SKE's key verify callback to the client library's
6308 KE protocol context. Affected files lib/silcclient/protocol.[ch].
6310 * Removed the statement that server (or router) must send USERS
6311 command reply when joining to the channel so that the client
6312 knows who are on the channel. Instead, the client list and
6313 client's mode list is now sent in the JOIN command reply to the
6314 client who joined channel. This is better solution.
6316 * Added function silc_server_get_users_on_channel and function
6317 silc_server_save_users_on_channel to the silcd/server.[ch].
6319 * Removed function silc_server_command_send_users from the
6322 * Do not show topic on the client library anymore. The topic is
6323 sent in the command reply notify to the application and the
6324 application must show the topic now.
6326 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6328 * Added client searching by nickname hash into the IDENTIFY and
6329 WHOIS commands in the server as they were clearly missing from
6330 them. Affected file is silcd/command.c.
6332 * Fixed a bug in private message receiving in the client library.
6333 The remote ID was freed and it wasn't supposed, now it is
6336 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6338 * Minor fix to the channel payload; allocate the data area, as it
6339 needs to be of specific length.
6341 * If the key agreement port is zero then the operating
6342 system will define the bound port. Affected files are
6343 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
6345 * Added new function silc_channel_payload_decrypt into the file
6346 lib/silccore/silcchannel.[ch].
6348 * Moved the channel message etc, check from silc_packet_decrypt
6349 to applications. The library calls now a generic
6350 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
6351 when the packet is either normal or special. This was done to
6352 allow more wide range of checking that was not allowed when
6353 the code was in library. Now applications can do virtually any
6354 checks to the packet and return to the library the decision how
6355 the packet should be processed. Affected files are
6356 lib/silccore/silcpacket.[ch].
6358 Added silc_server_packet_decrypt_check to the server and
6359 silc_client_packet_decrypt_check to the client library.
6361 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
6362 to send with specified source and destination information.
6364 * Channel message delivery between routers was broken after the
6365 channel key distribution was fixed earlier. The channel key
6366 was used be to distributed to other routers as well which is not
6367 allowed by the protocol. Now this is fixed and channel keys
6368 really are cell specific and the channel message delivery between
6369 routers comply with the protocol specification.
6371 * Fixed various commands in server to check also the global list
6372 for the channel entry and not just the local list. The affected
6373 file silcd/command.c.
6375 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6377 * Added assert()s to buffer formatting and unformatting routines
6378 to assert (if --enable-debug) when error occurs. Affected
6379 file: lib/silcutil/silcbuffmt.c.
6381 * Changed to auto-reconnect to check whether the remote host is
6382 router and register the re-connect timeout if it is. It used
6383 to check that whether we are normal server, but router must do
6384 auto-reconnect with another router as well. Affected file
6387 * Removed the [<key len>] option from CMODE command as the cipher
6388 name decides the key length, nowadays. See the defined ciphers
6389 from the protocol specification.
6391 * Added [<hmac>] option to the CMODE command to define the HMAC
6392 for the channel. Added SILC_CMODE_HMAC channel mode.
6394 * Added [<hmac>] option for the JOIN command so that user can
6395 select which HMAC is used to compute the MACs of the channel
6398 * Added Hmac field to the Channel Message Payload. The integrity
6399 of plaintext channel messages are now protected by computing
6400 MAC of the message and attaching the MAC to the payload. The
6401 MAC is encrypted. Now, it is clear that this causes some
6402 overhead to the size of the packet but rationale for this is that
6403 now the receiver can verify whether the channel message decrypted
6404 correctly and also when private keys are set for the channel the
6405 receiver can decrypt the packet with several keys and check from
6406 the MAC which key decrypted the message correctly.
6408 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
6409 lib/silccrypt/silccipher.[ch].
6411 * Added silc_hash_len to return the digest length into the
6412 lib/silcrypt/silchash.[ch].
6414 * Rewrote parts of Silc Channel Payload interface in the
6415 lib/silccore/silcchannel.[ch]. The encode function now also
6416 encrypts the packet and parse function decrypts it.
6418 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6420 * Fixed a minor formatting bug in the SKE's key material processing.
6421 It actually might have processed the keys wrong way resulting
6424 * Redefined the mandatory HMAC algorithms and added new algorithms.
6425 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
6426 and hmac-md5 truncated to 96 bits. The mandatory is now
6427 hmac-sha1-96. Rest are optional (including the one that used
6428 to be mandatory). Rationale for this is that the truncated HMAC
6429 length is sufficient from security point of view and can actually
6430 make the attack against the HMAC harder. Also, the truncated
6431 HMAC causes less overhead to the packets. See the RFC2104 for
6434 * Added new [hmac] configuration section. The SKE used to use
6435 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
6436 is of course wrong. The official names that must be proposed in
6437 the SKE are the ones defined in the protocol specification
6438 (hmac-sha1-96 for example). The user can configure any hmac
6439 using any hash function configured in the [hash] section. At
6440 least, the mandatory must be configured.
6442 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
6444 * Added HMAC list to the SKE proposal list. It has now both
6445 hash algorithm list and HMAC list. This makes the protocol
6446 incompatible with previous versions. The SKE now seems to work
6447 the way it is supposed to work, for the first time actually.
6449 * Defined plain Hash algorithms to the protocol specification.
6452 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6454 * Implemented support for key agreement packets into the server.
6455 Added functions silc_server_key_agreement and
6456 silc_server_send_key_agreement. Other than these functions,
6457 server has nothing to do with this packet.
6459 * Added support for private message key packets into the server.
6460 Added functions silc_server_private_message_key and
6461 silc_server_send_private_message_key.
6465 * Changed the silc_[client|server]_protocol_ke_set_keys to be
6466 called in the protocol's final callback instead in the END
6467 protocol state. This makes a little more sense and in the same
6468 time in client we can use the same protocol routines for normal
6469 key exchange and to key agreement packet handling as well.
6471 * Added to both client's and server's KE protocol context the
6472 SilcSKEKeyMaterial pointer to save the key material. We will
6473 bring the key material to the protocol's final callback by doing
6474 this. The final callback must free the key material.
6476 * Added SKE's packet_send callback into client's KE protocol
6477 context so that the caller can choose what packet sending function
6478 is used. This way we can use different packet sending when
6479 doing normal SKE when doing key agreement packet handling (in
6480 the key agreement packet handling we do not want to encrypt
6483 * Implemented the responder side of the key agreement routines
6484 in the client. The client can now bind to specified port and
6485 accept incoming key negotiation. The key material is passed
6486 to the application after the protocol is over.
6488 * Implemented the processing of incoming Key Agreement packet
6489 in the client. Added function silc_client_key_agreement to
6492 * Implemented the intiator side of the key agreement routines
6493 in the client. The client can now initiate key agreement with
6494 another remote client. The key material is passed to the
6495 application after the protocol is over.
6497 * Created client_keyagr.c to include all the key agreement
6500 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
6501 SILC_TASK_CALLBACK except that it is not static.
6503 * Created client_notify.c and moved the Notify packet handling
6504 from the client.[ch] into that file.
6506 * Created client_prvmsg.c and moved all private message and
6507 private message key routines from the client.[ch] into that file.
6509 * Create client_channel.c and moved all channel message and
6510 channel private key routines from the client.[ch] into that file.
6512 * Changed silc_client_get_client_by_id_resolve to resolve with
6513 WHOIS command instead of IDENTIFY command, in the file
6514 lib/silclient/idlist.c.
6516 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6518 * Implemented the SKE's responder side to the Client library.
6520 * When FAILURE is received to the protocol do not trust it
6521 blindly. Register a timeout to wait whether the remote closes
6522 the connection as it should do it, only after that process the
6523 actual failure. This was changed to both client and server.
6525 * Added client_internal.h to include some of the structures
6526 there instead of client.h in lib/silcclient/.
6528 * Added function silc_task_unregister_by_callback to unregister
6529 timeouts by the callback function.
6531 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6533 * Some "Incomplete WHOIS info" errors has been appearing on the
6534 log files. Took away the entry->userinfo check from WHOIS
6535 reply sending. The entry->userinfo is now " " if client did not
6536 provide one. I thought this was fixed earlier but something
6537 is wrong still. Let's see if the error still appears.
6539 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6541 * Fixed a minor bug in the login when the channel key is
6542 re-generated in the server. It used to generate the key in
6543 wrong order and thus caused problems in the channel traffic.
6545 * Fixed a minor bug in channel key distsribution after
6546 KICK command. The key was not sent to the router even though
6549 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6551 * Added silc_ske_process_key_material_data as generic routine
6552 to process any key material as the SILC protocol dictates. The
6553 function is used by the actual SKE library but can be used by
6554 applications as well. This relates to the private message keys
6555 and the channel private keys since they must be processed the
6556 same way the normal SILC session keys. The protocol dictates
6557 this. Affected files: lib/silcske/silcske.[ch].
6559 Added also silc_ske_free_key_material to free the
6560 SilcSKEKeyMaterial structure.
6562 * Defined silc_cipher_set_key function to set the key for
6563 cipher without using the object's method function. The affected
6564 files: lib/silccrypt/silccipher.[ch].
6566 * Implemented silc silc_client_add_private_message_key,
6567 silc_client_add_private_message_key_ske,
6568 silc_client_del_private_message_key,
6569 silc_client_list_private_message_keys and
6570 silc_client_free_private_message_keys functions in the
6573 Added functions silc_client_send_private_message_key to send
6574 the Private Message Key payload and silc_client_private_message_key
6575 to handle incoming Private Message Key payload.
6577 * Added Cipher field to the Private Message Key payload to set
6578 the cipher to be used. If ignored, the default cipher defined
6579 in the SILC protocol (aes-256-cbc) is used.
6581 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6583 * Removed lib/silcclient/ops.h file.
6585 Redefined parts of the SILC Client Library API. Created new
6586 file silcapi.h that deprecates the ops.h file and defines the
6587 published Client Library API. Defined also private message key
6588 API and channel private key API into the file.
6590 This is the file that the application must include from the
6591 SILC Client Library. Other files need not be included by
6592 the application anymore.
6594 * Added new key_agreement client operation callback and also
6595 defined the Key Agreement library API for the application.
6597 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6599 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
6600 is used by clients to request key negotiation between another
6601 client in the SILC network. If the negotiation is started it
6602 is performed using the SKE protocol. The result of the
6603 negotiation, the secret key material, can be used for example
6604 as private message key.
6606 Implemented the Key Agreement payload into the files
6607 lib/silccore/silauth.[ch].
6609 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6611 * Redefined ciphers for the SILC protocol. Added some new ciphers
6612 and defined the key lengths for the algorithms. Changed the
6613 code accordingly. The default key length is now 256 bits.
6615 * Fixed SKE key distribution function silc_ske_process_key_material
6616 when the key length is more than 128 bits. The default key
6617 length in SILC is now 256 bits.
6619 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
6620 to indicate unsupported algorithm.
6622 * Renamed rijndael.c to aes.c and all functions as well.
6624 * Fixed a long standing channel key setting bug in client library.
6625 Weird that it has never surfaced before.
6627 * Fixed bug in channel deletion. If the entire channel is removed
6628 then it must also delete the references of the channel entry
6629 from the client's channel list as the client's channel entry and
6630 the channel's client entry share same memory.
6632 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6634 * Implemented CONNECT and SHUTDOWN commands in the client.
6636 * Implemented CLOSE command to the client.
6638 * Added the function silc_idlist_find_server_by_name into the
6639 files silcd/idlist.[ch].
6641 Added the function silc_idlist_find_server_by_conn into the
6642 files silcd/idlist.[ch].
6644 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6646 * DIE command was renamed to SHUTDOWN. Updated the both code
6649 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
6650 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
6652 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
6655 * Added function silc_server_create_connection function to create
6656 connection to remote router. My server implementation actually
6657 does not allow router to connect to normal server (it expects
6658 that normal server always initiates the connection to the router)
6659 so the CONNECT command is only good for connecting to another
6662 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6664 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
6665 or some other client was kicked from the channel.
6667 Implemented the handling of the notify type to both client
6670 Implemented silc_server_send_notify_kicked to send the KICKED
6671 notify. It is used to send it to the server's primary router.
6673 * Implemented the KICK command into server and client.
6675 * Added `query' argument to the silc_idlist_get_client function
6676 to indicate whether to query the client from server or not if
6679 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
6680 to indicate that the client is not channel founder.
6684 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6686 * Removed the rng context from SilcPacketContext structure and
6687 changed that the packet routine uses the Global RNG API.
6689 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6691 * Added support for quit message that client can "leave" on the
6692 channel when it quits the SILC. It is ditributed inside the
6693 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6695 Added silc_server_free_client_data that will take the
6696 signoff message as argument.
6698 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6700 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6702 * Updated parts of the protocol specification to keep it up
6705 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6707 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6708 payloads in one packet.
6710 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6711 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6712 use now the new List flag.
6714 * Also deprecated the following packet types: REPLACE_ID,
6715 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6717 * Added list support for Notify packet in server.
6719 * Added silc_server_send_notify_channel_change to send the
6720 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6721 the silc_server_send_replace_id.
6723 * Added silc_server_send_notify_nick_change to send the
6724 NICK_CHANGE notify type. Deprecates the function
6725 silc_server_send_replace_id.
6727 * Added silc_server_send_notify_join to send the JOIN notify type.
6728 Deprecates the function silc_server_send_new_channel_user.
6730 * Added silc_server_send_notify_leave to send LEAVE notify type.
6731 Deprecates the function silc_server_send_remove_channel_user.
6733 * Added silc_server_send_notify_cmode and
6734 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6735 types. Deprecates the silc_server_send_set_mode function.
6737 * Added SERVER_SIGNOFF notify type to indicate that server has
6738 quit. This means that all clients on the channel from that
6739 server will drop. This can be also used when netsplit happens.
6741 Deprecated REMOVE_ID packet type since it is not needed anymore
6744 Added silc_server_send_notify_server_signoff to send the
6745 SERVER_SIGNOFF notify type. Deprecates the function
6746 silc_server_send_remove_id.
6748 Added also silc_server_send_notify_signoff to send the
6749 SIGNOFF notify type.
6751 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6752 SILC protocol from this day on. Changed the protocol
6753 specification as well.
6755 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6756 notify type. It is used between routers to notify about
6757 topic changes on a channel.
6759 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6762 * Partly updated the protocol specification to comply with the
6763 changes now made. It is still though a bit outdated.
6765 * The JOIN notify type now takes one extra argument <Channel ID>.
6766 The packet used to be destined to the channel but now the
6767 JOIN type may be sent as list thus it is impossible to
6768 destine it to any specific channel. By adding this argument
6769 it is again possible.
6771 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6773 * Added CREDITS file. The CHANGES and CREDITS file will appear
6774 in the distribution as well.
6776 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6778 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6779 types in the server's silcd/packet_receive.c.
6781 * Implemented CMODE and CUMODE to work in router environment.
6783 * Fixed minor encoding and decoding buglet from the
6784 lib/silccore/silcmode.c.
6786 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6789 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6791 * Changed all SilcConfigServer* and silc_config_server* to
6792 SilcServerConfig* and silc_server_config*, respectively.
6795 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6797 * Associated the ID (client or server ID) to the Authentication
6798 Payload to avoid any possibility of forging. Updated the
6799 protocol specification and the code accordingly.
6801 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6803 * The RSA key length is now save to the RsaKey context in the
6804 key generation process in lib/silccrypt/rsa.c. The key length
6805 is now used to figure out the maximum size of the block allowed
6806 to be encrypted/signed.
6808 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6809 is equivalent to the silc_mp_mp2bin but does not allocate any
6812 * Changed silc_mp_mp2bin API to take length argument. If it is
6813 non-zero then the buffer is allocated that large. If zero, then
6814 the size is approximated using silc_mp_sizeinbase, which however
6817 * Created Global RNG API which is global RNG that application can
6818 initialize. After initializing, any routine anywhere in the
6819 code (including library) can use RNG without allocating a new
6820 RNG object. This was done to allow this sort of use of the
6821 RNG in code that has no chance to allocate RNG object. All
6822 applications currently allocate this and many routines in the
6823 library use this. Affected file lib/silccrypt/silcrng.[ch].
6825 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6826 it to use the Global RNG API.
6828 * Defined Authentication Payload into protocol specification that
6829 is used during SILC session to authenticate entities. It is
6830 used for example by client to authenticate itself to the server
6831 to obtain server operator privileges.
6833 Implemented this payload into the lib/silccore/silcauth.[ch].
6834 Implemented also routines for public key based authentication
6835 as the new protocol specification dictates.
6837 Moved definitions of different authentication methods from
6838 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6840 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6841 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6842 silc_pkcs_verify_with_hash functions into the file
6843 lib/silccrypt/silcpkcs.[ch].
6845 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6847 * The client entry's userinfo pointer must be always valid.
6848 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6849 will fail since it requires the userinfo. Now, the userinfo
6850 is allocated as "" if actual userinfo does not exist. Actually,
6851 it must exist and it is totally Ok to drop client connections
6852 that does not announce the userinfo. However, we will make
6853 this workaround for now.
6855 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6856 to return the remote port by socket.
6858 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6860 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6861 SILC_SERVER_PENDING_EXEC and added an new macro
6862 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6863 data or when error occurs while processing the pending command.
6865 Added new argument `destructor' into silc_server_command_pending
6866 and to the SilcServerCommandPending object. This destructor is
6867 now called after calling the pending callback or if error occurs
6868 immediately. If error occurs the actual pending callback won't
6869 be called at all - only the destructor. The destructor may be
6870 NULL if destructor is not needed.
6872 All this applies for client library code as well. Similar
6873 changes were made there as well for the pending commands.
6875 In the client, the application must now allocate the
6876 SilcClientCommandContext with the silc_client_command_alloc
6879 * Added reference counter to the SilcServerCommandContext. Added
6880 function silc_server_command_alloc and silc_server_command_dup
6883 Same type of functions added to the client library for the same
6886 * Removed the cmd_ident from IDListData away since it is now
6887 global for all connections. It is the command identifier used
6888 in command sending and with pending commands. The affected file
6891 * Added reference counter to the SilcSocketConnection objecet to
6892 indicate the usage count of the object. The object won't be
6893 freed untill the reference counter hits zero. Currently only
6894 server uses this, and client ignores it. The client must be
6895 set to use this too later. The affected files are
6896 lib/silccore/silcsockconn.[ch]. Added also the function
6897 silc_socket_dup to increase the reference counter.
6899 This was mainly added because it is possible that the socket
6900 is removed underneath of pending command or other async
6901 operation. Now it won't be free'd and proper DISCONNECTING
6902 flags, etc. can be set to avoid sending data to connection that
6903 is not valid anymore.
6905 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6906 the connection. After that it sets SILC_SET_DISCONNECTED.
6907 It is, however, possible that the socket data is not still freed.
6908 The silc_server_packet_process now checks that data is not
6909 read or written to connection that is DISCONNECTED. The socket
6910 get's freed when the reference counter hits zero.
6912 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6914 * Changed the client operation API: channel_message operation's
6915 `sender' is now the client entry of the sender, not the nickname
6916 and the `channel' is the channel entry, not the channel name.
6918 In the private_message operation the `sender' is now also the
6919 client entry of the sender not the nickname.
6921 Affected file is lib/silcclient/ops.h and all applications
6922 using the client operations.
6924 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6926 * Moved the calling of ops->connect() from connect_to_server_final
6927 into receive_new_id functin since that is the point when the
6928 client is actually allowed to send traffic to network. The
6929 affected file is lib/silcclient/client.c.
6931 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6933 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6934 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6935 (if needs broadcasting) instead of broadcasting the packets one
6936 by one which would make a burst in the network traffic.
6938 * Added `broadcast' argument to the functions in silcd/server.[ch]
6939 silc_server_create_new_channel[_with_id] to indicate whether
6940 to send New Channel packet to primary router.
6942 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6944 * Added new function into the silcd/server.[ch] files:
6945 silc_server_create_new_channel_with_id to create new channel with
6946 already existing Channel ID.
6948 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6949 lib/silccore/silcpacket.h. This packet is used t send list of
6950 Set Mode payloads inside one packet. Server uses this to set
6951 the modes for the channels and clients on those channels, that it
6952 announced to the router when it connected to it. The protocol
6953 specification has been updated accordingly.
6955 * The silc_server_new_channel did not handle the packet coming
6956 from normal server as it normally does not send that. However,
6957 when it announces its channels it does send it. Implemented
6958 the support for that.
6960 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6961 into the file lib/silccore/id.h.
6963 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6965 * Fixed memory leaks in the functions silc_idlist_del_client,
6966 silc_idlist_del_channel and silc_idlist_del_server in the file
6967 silcd/idlist.c. All of those leaked like a sieve.
6969 * Fixed some small memory leaks in the client's function
6970 silc_client_notify_by_server.
6972 * Added functions into silcd/server.c: silc_server_announce_clients,
6973 silc_server_announce_channels and silc_server_announce_server.
6974 These functions are used by normal and router server to announce
6975 to its primary router about clients, channels and servers (when
6976 router) that we own. This is done after we've connected to the
6979 These functions effectively implements the following packet types:
6980 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6981 and SILC_PACKET_NEW_ID_LIST.
6983 * Added new functions into the silcd/packet_receive.[ch]:
6984 silc_server_new_id_list, silc_server_new_channel_list and
6985 silc_server_new_channel_user_list to handle the incoming
6986 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6988 * Added support of changing Channel ID in the function
6989 silc_server_replace_id. If the server that announces a channel
6990 to the router already exists in the router (with same name but
6991 with different Channel ID), router is responsible to send
6992 Replace ID packet to the server and force the server to change
6993 the Channel ID to the one router has.
6995 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6996 client that the Channel ID has been changed by the router. The
6997 normal server sends this to the client. Client must start using
6998 the new Channel ID as the channel's ID.
7000 Implemented handling of this new type into lib/silcclient/client.c
7001 into the function silc_client_notify_by_server.
7003 * Added new function silc_idlist_replace_channel_id into the files
7004 silcd/idlist.[ch] to replace the Channel ID.
7006 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7008 * Call silc_server_command_identify_check always when processing
7009 the IDENTIFY command in silcd/command.c
7011 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7013 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
7014 send keepalive packets. The packet can be sent by clients,
7015 servers and routers.
7017 Added function silc_socket_set_heartbeat into the file
7018 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
7019 If not set, the heartbeat is not performed. The actual
7020 heartbeat is implemented in the low level socket connection
7021 library. However, application is responsible of actually
7024 Added silc_server_send_heartbeat to send the actual heartbeat
7025 packet into silcd/packet_send.[ch]. Server now performs
7026 keepalive with all connections.
7028 * Added silc_task_get_first function into lib/silcutil/silctask.c
7029 to return the timeout task with shortest timeout. There was a bug
7030 in task unregistration that caused problems. TODO has been
7031 updated to include that task system must be rewritten.
7033 * The client library will now resolve the client information when
7034 receiving JOIN notify from server for client that we know but
7035 have incomplete information.
7037 * Rewrote parts of silc_server_remove_from_channels and
7038 silc_server_remove_from_one_channel as they did not remove the
7039 channel in some circumstances even though they should've.
7041 * Encryption problem encountered in server:
7043 The LEAVE command used to send the Channel Key packet to the
7044 router immediately after generating it. However, the code
7045 had earlier sent Remove Channel user packet but not immediately,
7046 ie. it was put to queue. The order of packets in the router
7047 was that Channel Key packet was first and Remove Channel User
7048 packet was second, even though they were encrypted in the
7049 reverse order. For this reason, MAC check failed. Now, this
7050 is fixed by not sending the Channel Key packet immediately but
7051 putting it to queue. However, this is more fundamental problem:
7052 packets that are in queue should actually not be encrypted
7053 because packets that are sent immediately gets encrypted
7054 actually with wrong IV (and thus MAC check fails). So, packets
7055 that are in queue should be encrypted when they are sent to
7056 the wire and not when they put to the queue.
7058 However, the problem is that the current system has not been
7059 designed to work that way. Instead, the packet is encrypted
7060 as soon as possible and left to the queue. The queue is then
7061 just purged into wire. There won't be any fixes for this
7062 any time soon. So, the current semantic for packet sending
7065 o If you send packet to remote host and do not force the send
7066 (the packet will be in queue) then all subsequent packets to the
7067 same remote host must also be put to the queue. Only after the
7068 queue has been purged is it safe again to force the packet
7071 o If you send all packets immediately then it safe to send
7072 any of subsequent packets through the queue, however, after
7073 the first packet is put to queue then any subsequent packets
7074 must also be put to the queue.
7076 Follow these rules and everything works fine.
7078 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7080 * Added new function silc_server_remove_clients_by_server to
7081 remove all client entries from ID list when the server connection
7082 is lost. In this case it is also important to invalidate all
7083 client entires as they hold the invalid server entry. This
7084 fixes fatal bug when server has lost connection and will reconnect
7087 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7089 * Made some sanity checks to silc_server_daemonise like to check
7090 whether the requested user and group actually exists.
7092 * Added sanity check to SKE's silc_ske_responder_finish to check
7093 that the public and private key actually is valid.
7095 * Invalidate the client's nickname when receiving Replace ID
7096 packet and the Client ID is being replaced. This means that the
7097 server will query the nickname if someone needs it (client)
7100 * Sort the ID Cache in client library when the ID Cache data
7101 has changed (needs sorting).
7103 * Do not allow for SILC client to create several connections to
7104 several servers. The client does not support windows right now
7105 and generating multiple connections causes weird behaviour.
7107 Irssi-silc client does support windows and can handle several
7108 connections without problems, see: www.irssi.org and SILC plugin.
7110 * Fixed some places where client was added to the IDList. The
7111 rule of thumb is following (in order to get everything right):
7112 If the client is directly connected local client then the
7113 `connection' argument must be set and `router' argument must be
7114 NULL to silc_idlist_add_client function. If the client is not
7115 directly connected client then the `router' argument must
7116 bet set and the `connection' argument must be NULL to the
7117 silc_idlist_add_client function.
7119 * The funtion silc_server_packet_send_local_channel actually did
7120 not check whether the client was locally connected or not. It
7121 does that now. Fixed a bug related to LEAVE command.
7123 * Fixed Remove Channel User payload parsing bug in server's
7124 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
7126 * The server's silc_server_save_channel_key now checks also the
7127 global ID list for the channel as it might not be in the local
7128 list. Fixed a bug related to LEAVE command.
7130 * Is this the end of the [<unknown>] buglet that has been lurking
7131 around for a long time? A little for loop fix in server's
7132 silc_server_command_whois_parse that is used by both IDENTIFY
7133 and WHOIS command. At least, this was a clear bug and a cause
7134 of one type of [<unknown>] buglet.
7136 * WHOIS and IDENTIFY commands call the function
7137 silc_server_command_[whois/identify]_check function even if
7138 we are not router server.
7140 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7142 * Added --with-gmp configuration option. If set the GMP
7143 is always compiled in the SILC source tree. If not set then
7144 it is checked whether the system has the GMP3 installed. If
7145 it has then the GMP won't be compiled (the system's headers
7146 and library is used), if it doesn't have it then the GMP is
7147 compiled in the SILC source tree.
7149 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7151 * Changed RSA private exponent generation to what PKCS #1
7152 suggests. We try to find the smallest possible d by doing
7153 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
7154 not security fix but optimization.
7156 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7158 * Added new config entry [Identity] to fork the server and run
7159 it as specific user and group. A patch from Bostik.
7161 * Imported Dotconf configuration library into lib/dotconf.
7162 This will be used to create the SILC configuration files later.
7163 It will appear in the distsribution after this commit.
7165 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7167 * A big code auditing weekend happening. Auditing code for
7168 obvious mistakes, bugs and errors. Also, removing any code
7171 Removed files for being obsolete:
7173 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
7174 inline in the file lib/silcutil/silcbuffer.h)
7176 o lib/silcutil/silcbufutil.c (the header has inline versions)
7178 Changed code to fix possible error conditions:
7180 o The buffer formatting routines now check that the destination
7181 buffer really has enough space to add the data. This applies for
7182 both buffer formatting and unformatting
7183 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
7184 unformatting was changed to accomodate following rules:
7185 XXX_*STRING_ALLOC will allocate space for the data into the pointer
7186 sent to the function while XXX_*STRING will not allocate or copy
7187 the data into the buffer. Instead it sets the pointer from the
7188 buffer into the pointer sent as argument (XXX_*STRING used to
7189 require that the pointer must be allocated already). This change
7190 makes this whole thing a bit more consistent and more optimized
7191 (note that the data returned in the unformatting with XXX_*STRING
7192 must not be freed now). The routines return now -1 on error.
7194 o Tried to find all code that use buffer_format and buffer_unformat
7195 and added return value checking to prevent formatting and
7196 especially unformatting errors and possible subsequent fatal
7199 o Changed ske->x and ske->KEY to mallocated pointers in
7200 lib/silcske/silcske.h. Fixed possible data and memory leak.
7202 o Added return value checking to all *_parse* functions. Fixed
7203 many memory leaks as well.
7205 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
7206 so that buffer overflows would not happen. All code now also
7207 checks the return value as it can fail.
7209 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7211 * Added reconnection support to server if the normal server looses
7212 its connection to the router (for example if router is rebooted).
7213 The server performs normal reconnection strategy implemented
7214 to the server. Affected file silcd/server.c.
7216 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7218 * Added new packet type SILC_PACKET_SET_MODE that is used to
7219 distribute the information about changed modes (for clients,
7220 channels and clients channel modes) to all routers in the
7221 network. Updated the protocol specification accordingly.
7223 Added functions into silcd/packet_send.c and
7224 silcd/packet_receive.c: silc_server_send_set_mode,
7225 silc_server_set_mode.
7227 Added new files silcmode.[ch] into lib/silccore that implements
7228 the encoding and decoding of Set Mode Payload. Added new type
7229 SilcSetModePayload. Moved the definitions of different modes
7230 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
7232 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7234 * Oops, a little mistake in server's connection authentication
7235 protocol. The protocol is not ended with FAILURE but with
7236 SUCCESS if the authentication is Ok. :) Affected file is
7239 * Implemented NICK_CHANGE notify handling in server in the file
7240 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
7241 the local clients on the channel. After the changing nickname
7242 in router environment snhould work and the [<unknown>] nickname
7243 should appear no more.
7245 The silc_server_replace_id function that receives the Replace ID
7246 payload now sends the NICK_CHANGE notify type also in the file
7247 silcd/packet_receive.c
7249 * Changed WHOIS and IDENTIFY command to support the maximum amount
7250 of arguments defined in protocol specs (3328 arguments). This
7251 fixed a bug that caused problems when there were more than three
7254 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7256 * Added extra parameter, command identifier, to the
7257 silc_client_send_command so that explicit command identifier
7260 Changed that ID list routines uses specific command identifier
7261 when sending WHOIS/IDENTIFY requests to the server so that they
7262 can be identified when the reply comes back.
7264 Affected files lib/silcclient/command.[ch],
7265 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
7267 * Added `sender' argument to silc_server_packet_send_to_channel
7268 to indicaet the sender who originally sent the packet to us
7269 that we are now re-sending. Ignored if NULL. Affected file
7270 silcd/packet_send.[ch].
7272 * Added some server statistics support in silcd/server_internal.h
7273 SilcServerStatistics structure and around the server code. Also
7274 send some nice statistics information when client is connecting
7277 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7279 * Fixed channel ID decoding in server's JOIN command reply in
7280 silcd/command_reply.c
7282 * Fixed braodcasting of replace ID payload to not to send it if
7283 we are standalone server in silcd/packet_receive.c.
7285 * Fixed all channel message sending routines to not to send
7286 packets to clients that has router set, since they are routed
7287 separately in the same function earlier. Affects file
7288 silcd/packet_send.c and all channel packet sending functions.
7290 * In USERS reply, res_argv[i] are not allocated, the table
7291 is allocated. Thus changed that free the table, not its
7294 * In server's whois_check and identify_check if the client is
7295 locally connected do not send any WHOIS commands - they are not
7298 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7300 * Fixed some minor bugs in client when sending WHOIS command. The
7301 arguments was in wrong order.
7303 * Removed statis function add_to_channel from server in
7304 silcd/command.c that was previously used with the joining but
7307 * Tested USERS command in router environment successfully with two
7308 routers, two servers and two clients.
7310 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7312 * Reorganized the USERS command and command reply in client library
7313 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
7314 When the command is given by user we register a pending command
7315 callback that will reprocess the command after the reply has been
7316 received from the server. When reprocessing the packet we then
7317 display the information. Thus, the USERS information is displayed
7318 now in the command callback instead of in the command reply
7319 callback. The processing of the command is same as previously
7320 when server has sent the command reply in the JOINing process.
7322 * Added to USERS command in silcd/command_reply.c to join the client,
7323 we didn't use to know about, to the channel after we've created
7324 a client entry for it. Also, for clienet we did know already still
7325 check whether it is on the channel or not and add it if not.
7327 * Removed silc_server_command_join_notify as the function and its
7330 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7332 * Changed the client's pending command handling to the same as the
7333 server's pending command handling. It is also now possible to
7334 execute command reply functions from other command reply
7335 function as the function callbacks for commands and command
7336 replies are one and same. The pending commands are not static
7337 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
7338 in client connection context. Thus, pending commands are server
7339 connection specific as it is convenient.
7341 Changed the function silc_client_command_pending and
7342 silc_client_command_pending_del and added new function
7343 silc_client_command_pending_check. Removed the
7344 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
7347 * Added cmd_ident, current command identifier, to the client
7348 connection context in lib/silcclient/client.h to keep track on
7349 command identifiers used in command sending. Client's command reply
7350 function handling now supports the mandatory command identifiers.
7352 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
7353 funtions in client to fully support pending command callbacks.
7355 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
7356 as one of the arguments to the application in the command reply
7359 * NOTE: The FORWARDED flag is depracated. It used to be depracated
7360 before first releasing SILC but came back. Now it is removed again
7361 and should come back nomore. The FORWARDED flag was used only
7362 by the JOINing procedure by forwarding the command packet to router.
7363 Now, the JOINing procedure has been changed to more generic (due
7364 to various router environment issues) and FORWARDED is not needed
7365 anymore for anything. The protocol specification is yet to be
7368 Now, removed silc_server_packet_forward from server and the flag
7369 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
7371 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7373 * Renamed NAMES command to USERS command. The NAMES was named that
7374 due to historical reasons. Now it is renamed. Also, rewrote
7375 parts of the USERS command. The nickname list is not sent anymore
7376 by the server. Only Client ID and mode lists are sent in the USERS
7377 command. Changed this also to the protocol specification.
7379 The client now resolves the names and stuff after it receives
7380 the USERS list from the server when joining to the channel.
7382 * WHOIS and IDENTIFY commands has been changed to support multiple
7383 Client ID's per command. One can now search for multiple users
7384 in the network by sending only one WHOIS or IDENTIFY command.
7385 Changed the code and the protocol specifications.
7387 * Removed silc_server_command_identify_parse and changed that IDENTIFY
7388 uses silc_server_command_whois_parse to parse the request. */
7390 * If normal server, do not parse the WHOIS and IDENTIFY requests
7391 before sending it to the router. Saves some time.
7393 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7395 * Fixed JOIN command on client library. Wrong number of arguments
7396 used to crash the client.
7398 * Added silc_server_channel_has_global function to check whether
7399 channel has global users or not.
7401 * Added silc_server_channel_has_local function to check whether channel
7402 has locally connected clients on the channel.
7404 * The silc_server_remove_from_one_channel now checks whether the
7405 channel has global users or not after given client was removed from
7406 the channel. It also checks whether the channel has local clients
7407 on the channel anymore. If it does not have then the channel entry
7408 is removed as it is not needed anymore.
7410 * The silc_server_notify now checks on JOIN notify whether the joining
7411 client is one of locally connected or global. If it is global then
7412 the channel has now global users on the channel and that is marked
7413 to the channel entry. Also, it now saves the global client to
7414 global list who is joining and JOINs it to the channel. This is
7415 for normal server, that is.
7417 Changed silc_server_send_notify_on_channel,
7418 silc_server_packet_relay_to_channel and
7419 silc_server_packet_send_to_channel check if we are normal server
7420 and client has router set (ie. global client) do not send the
7421 message to that client, as it is already routed to our router.
7423 * Implemented LEAVE notify type handling in silc_server_notify
7426 * Tested LEAVE command in router environment successfully. Tested
7427 with two routers, two servers and two clients.
7431 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
7433 * Implemented SIGNOFF notify type handling in silc_server_notify
7436 * silc_server_remove_id now removes the client entry from all channels
7437 it has joined and thusly sends SIGNOFF notify type.
7439 * Rewrote the NAMES list generation in server by removing two excess
7440 loops. The lists are created now inside one loop.
7442 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7444 * silc_server_remove_channel_user checks now also global list
7445 for channel and client.
7447 * silc_server_new_channel_user checks now both local and global
7448 list for channel and client. Fixed a bug in client id decoding.
7449 Used to decode wrong buffer.
7451 * silc_server_channel_message checks now both local and global
7452 list for channel entry.
7454 * Tested channel joining (hence JOIN) in router environment
7455 successfully. Tested with two routers, two servers and two
7458 * Tested channel message sending in router environment successfully.
7460 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7462 * Added silc_server_save_channel_key into server.[ch] to save the
7463 received channel key in Channel Key payload processing. It is
7464 also used in JOIN command reply handling.
7466 Equivalent function silc_client_save_channel_key added into
7467 client.[ch] into client library.
7469 * Changed JOIN command reply to send information whether the channel
7470 was created or not (is existing already) and the channel key
7471 payload. Changed protocol specs accordingly.
7473 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
7474 the request was sent by ID and not by nickname. Crashed on
7477 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7479 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
7480 now correctly save the received data.
7482 * silc_server_free_sock_user_data now notifies routers in the
7483 network about entities leaving the network.
7485 At the same time implemented functions silc_server_remove_id
7486 and silc_server_send_remove_id to receive and send REMOVE_ID
7487 packets. The packet is used to notify routers in the network
7488 about leaving entities. The ID removed will become invalid in
7491 * Added function silc_idlist_del_server into server. Removes and
7492 free's server entry from ID list.
7494 * silc_server_private_message function now checks, if we are router,
7495 that the destination ID really is valid ID, naturally.
7497 * In router when NEW_ID packet is received (for new client) the
7498 hash of the Client ID is saved in the ID Cache but the
7499 client->nickname is set to NULL, instead of putting the hash
7502 IDENTIFY command now also checks that client->nickname must be
7503 valid. If it is not if will request the data from the server who
7504 owns the client. Added new function
7505 silc_server_command_identify_check.
7507 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
7508 to set the command to already allocated Command Payload.
7510 * Tested private message sending in router environment with two
7511 routers, two servers and two clients. Fixed minor bugs and now
7514 * Fixed segfault from client's NAMES command. Used to crash if
7517 * Forwarded packets must not be routed even if it is not destined
7518 to the receiver. Changed server code comply with this.
7520 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7522 * Added `require_reverse_mapping' boolean value to ServerParams
7523 structure. If TRUE (not default) the server will require that
7524 the connecting host has fully qualified domain name.
7526 If the reverse mapping is not required and hostname could not be
7527 found the IP address is used as hostname.
7529 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7531 * Implemented version string checking to both client and server.
7532 The check is incomplete currently due to the abnormal version
7533 strings used in development version of SILC.
7535 * Changed all command functions in server to use the new
7538 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7540 * Changed char *data to unsigned char *data in ID Cache system to
7541 support binary data as ID Cache data. Changed code to support
7542 binary data in lib/silccore/idcache.c.
7544 * Renamed silc_server_packet_relay_command_reply to
7545 silc_server_command_reply as it is normal packet receiving
7546 function. Rewrote the function to accept command replys for
7547 servers and not only for clients.
7549 * Mark remote router always as registered server if we are connecting
7550 to it. Otherwise, commands sent by the router to us are ignored.
7552 * All ID List find routines now returns the ID Cache Entry pointer
7553 as well if requested.
7555 * WHOIS command works now in router environment, tested with two
7556 routers, two servers and two clients.
7558 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
7559 in router environment (as it is almost equivalent to WHOIS) but
7560 hasn't been tested thoroughly. Added new functions:
7562 silc_server_command_identify_parse
7563 silc_server_command_identify_send_reply
7564 silc_server_command_identify_from_client
7565 silc_server_command_identify_from_server
7567 * Disabled route cache adding because adding two different ID's with
7568 same IP replaces the old cache entry thus giving wrong route.
7569 The entry->router->connection is always the fastest route anyway
7570 so route cache may not be needed. Of course, new routes maybe
7571 established after receiving the ID when the entry->router->connection
7572 might not be anymore the most optimal.
7574 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7576 * Add route cache for received ID for fast routing.
7578 * Added silc_server_packet_route to route received packet on router
7579 that is not destined to us.
7581 * Renamed silc_server_get_route to silc_server_route_get.
7583 * Added id_string and id_string_len fields into SilcServer to
7584 include encoded ServerID for fast comparing without excess
7585 encoding of the ID's.
7587 * Cleaned up WHOIS command on server side. Added following static
7590 silc_server_command_whois_parse
7591 silc_server_command_whois_check
7592 silc_server_command_whois_send_reply
7593 silc_server_command_whois_from_client
7594 silc_server_command_whois_from_server
7596 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
7597 arguments in command replies. All command functions should be
7598 updated to use this macro.
7600 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7602 * Minor typo fixes on command reply handling on server.
7604 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7606 * Added silc_server_command_add_to_channel internal routine to add
7607 the client to the channel after router has created the channel and
7608 sent command reply to the server.
7610 * Added generic silc_server_send_command to send any command from
7613 * Use static buffer with ID rendering instead of duplicating data.
7615 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7617 * Fixed a channel user mode bug when joining to a channel server gave
7618 everybody channel founder rights, oops.
7620 * We mark ourselves as the router of the incoming server connection
7621 if we are router ourselves. This way we can check in some packet
7622 sending functions whether it is locally connected server. For
7623 incoming router connections we put NULL.
7625 * For router sending packets locally means now always sending the
7626 packet cell wide; to local clients and local servers. For normal
7627 server sending packet locally means sending it to only local
7630 * Fixed the JOIN command to really work in router environment. If the
7631 channel is created it is always created by the router. Router is
7632 also responsible of making the initial joining to the channel,
7633 sending JOIN notify to the sending server and distributing
7634 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
7635 does not exist server doesn't do anything else but forward the
7636 command to the router which performs everything.
7638 * Added silc_server_send_channel_key function to send the Channel Key
7641 * Added silc_server_create_channel_key to create new channel key. The
7642 channel key is now re-generated everytime someone joins or leaves
7643 a channel, as protocol dictates. Note: channel->key_len is the
7646 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7648 * Splitted server.[ch] finally. Created now packet_send.[ch] and
7649 packet_receive.[ch] to separate packet sending and receiving
7650 routines. The server.[ch] now includes everything else including
7651 actual packet processing (writing and reading data) and other
7654 Renamed silc_server_private_message_send_internal to
7655 silc_server_send_private_message. The routine is still though
7656 used only to relay private messages as server does not send
7657 private messages itself.
7659 Renamed silc_server_new_channel to silc_server_create_new_channel
7660 and added new function sicl_server_new_channel that handles the
7661 incoming New Channel packet. Added also new sending function
7662 silc_server_send_new_channel to send New Channel Payload.
7664 * Added new function silc_server_notify to process incoming notify
7665 packet to the server/router. Server may then relay the notify
7666 to clients if needed.
7668 * Added new function silc_server_new_channel_user to process incoming
7669 New Channel User packet. Router will redistribute the packet and
7670 send JOIN notify to its local clients and locally connected servers
7671 if needed. Normal server will send JOIN notify to its local client
7672 on same channel when received this packet. Added also corresponding
7673 sending function silc_server_send_new_channel_user to sent the
7676 * Added boolean route argument to send_notif_to_channel and
7677 packet_send_to_channel functions to attempt to route the packet
7678 if it is TRUE and send only locally if it is FALSE.
7680 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7682 * silc_server_replace_id now broadcasts the received replace ID
7683 packet if it is not broadcast packet already. The router must
7684 broadcast to inform other routers about changed ID.
7686 * Added backpointer to server's router into SilcServer context in
7687 silcd/server_internal.h.
7689 * Fixed silc_server_packet_broadcast to send correct broadcast
7692 * The channel key is now distributed to the local client as soon
7693 as it is received from the router (in router environment) so that
7694 no other packet may be sent for the channel until client has
7697 * silc_server_remove_channel_user now broadcasts the received
7698 Remove Channel User packet if it is not broadcast packet already.
7699 The router must broadcast to inform other routers about removed
7702 * Added users field into SilcPacketContext that is a reference count
7703 of the context. One can increase the reference count by calling
7704 silc_packet_context_dup which is now changed to just increase the
7705 reference count instead of duplicating the data. The reference
7706 count is decresed by calling silc_packet_context_free that will
7707 free the data after the reference count hits zero.
7709 For now on the packet context and everything allocated into it
7710 (including the raw packet from network) must be freed by calling
7711 the new silc_packet_context_free function. Added also new function
7712 silc_packet_context_alloc that must be used now to allocate the
7713 context. This also means that if a routine is asynchronous from
7714 silc_[client/server]_packet_parse_type the packet context must
7715 be duplicated by calling silc_packet_context_dup. Otherwise it
7716 gets free'd after silc_[client/server]_packet_parse_type returns.
7717 Also, one must remember that if packet is duplicated then its
7718 reference count must be decresed by calling the free function as
7719 many times as it was duplicated.
7721 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7722 from both client and server.
7724 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7726 * Made joining to a channel working in router environment.
7728 * Cleaned up JOIN command on server side and create function
7729 silc_server_command_join_channel internal routine to make the
7732 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7734 * Changed silc_command_pending list to SilcDList. Also, added
7735 `ident' field to SilcServerCommandPending structure to identify
7736 the reply and to call correct callback.
7738 Added silc_server_command_pending_check function to replace the
7739 corresnponding macro. The silc_command_pending list is not
7742 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7743 to set identifier to previously allocated Command Payload. It
7744 is used to set identifier for command when resending Command
7747 * Added silc_command_payload_encode_payload to encode Command
7748 Payload buffer from SilcCommandPayload structure.
7750 * Added silc_argument_payload_encode_payload to encode Argument
7751 payload buffer from SilcArgumentPayload structure.
7753 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7755 * Changed WHOIS command to support router connection on server side.
7756 The whois request is always sent to router unless the server is
7757 standalone server. After server has received the reply from the
7758 router will it send the reply to the client.
7760 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7761 broadcast received broadcast packet. The function is used only
7762 by router. The broadcast packet is always sent to the router's
7765 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7766 render given ID to printable string, for log files for example.
7768 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7770 * Made basic router to router connections working. At least they
7771 can now connect to each other but nothing really works the way
7772 they are supposed - yet.
7774 * Added new initiator token to RouterConnection configuration
7775 file in silcd/serverconfig.[ch]. It is used to tell whether we
7776 are the initiator to the remote router or whether we'll expect
7777 the other end to connect.
7779 * Moved registering of listener task to silc_server_init, hence
7780 the server starts listenning as soon as it is run, even if it
7781 does not have connections to other routers. Let's see how well
7784 * Changed default connection retry timeouts for more suitable in
7787 * Removed cipher and such arguments from silc_idlist_add_client
7788 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7789 Added new function silc_idlist_add_data to add the keys and stuff
7792 * Added SilcIDListData structure and added it to SilcClientEntry
7793 and SilcServerEntry as their first field in the structure. This
7794 way we can explicitly cast the ID entries to the SilcIDListData
7795 structure and get common data for the entries. In past, we had
7796 to first check what type of connection it is and then cast it to
7797 correct ID entry type. Now, we can directly cast the opaque
7798 pointer to the SilcIDListData (no matter what ID entry it actually
7799 is) and get the data needed.
7801 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7803 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7804 in some circumstances even if threre were timeout tasks, though not
7805 IO tasks, but tasks anyway. Now fixed.
7807 * Defined SilcServerConnection structure to hold connection specific
7808 stuff about directly connected servers and routers. The definition
7809 is currently in silcd/server_internal.h. I thought about having
7810 a bit more important role fro this struct but for now it is used
7811 only when connecting to other server (or router actually).
7813 * Added connecting retry support in server when connecting to
7814 router(s). The retry feature implement exponential backoff
7815 algorithm. Also, added SilcServerParams structure to hold default
7816 parameters for server. For now, it include these retry settings
7817 and are hard coded. After server is moded to be as Silc Server
7818 Library this structure will be more important.
7820 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7822 * Changed client librarys channel->clients table to SilcList and
7823 changed code accordingly.
7825 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7827 * Changed client's channel table to SilcList and changed code
7828 accordingly. Also changed SilcChannelClientEntry to include back-
7829 pointer to the channel so that client entry can use that structure
7830 as list as well and we have fast cross-reference to the channel.
7831 This change dramatically decreased the complexity of channel
7832 handling with client entry and vice versa (removed one extra
7833 loop when searching for channel entry from many functions).
7835 * Changed server->sim from table to SilcDList and changed code
7838 * NAMES command can now be used from user interface. It will show
7839 the user list on the channel, neatly.
7841 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7842 Code now saves realname of the user if it becomes available.
7844 * Renamed configure.in to configure.in.pre and made ./prepare
7845 script to automatically add correct version string to
7846 configure.in which it creates from configure.in.pre.
7848 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7850 * NAMES command reply now shows users mode with the nickname when
7853 * Moved silc_client_ch[u]mode[_char] functions from
7854 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7855 place sucks, they are utility functions and should be in some
7858 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7860 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7863 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7867 * Added TRQ (efficient deque and list library) into lib/trq. This is
7868 a very good list library that is currently used in the SILC. Defined
7869 SilcList API over the library because I didn't like the API very
7870 much. See lib/trq/silclist.h for the API and examples of how to
7871 use the API. Fixed various places in the code to use the new
7872 SilcList API. The SilcList is meant for lists that has a structure
7873 already defined as a list. It is not suitable to add just some
7874 context to the list (in TRQ, the context is the list actually).
7876 So, I defined SilcDList that can be used for the purpose where
7877 predefined list structure does not exit. This can be used as
7878 such list. Now some context just can be added to the SilcDList.
7879 Currently this list is not used in the SILC just yet, though there
7880 are a lot places where this can replace dynamically allocated
7881 tables and I will fix these places, later, to use SilcDList.
7882 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7883 and use TRQ internally).
7885 Also fixed some annoying warning messages that the original TRQ
7886 code generated. Also minor changes to TRQ's Makefile.in.
7888 * Added support for querying by Client ID to both WHOIS and
7889 IDENTIFY commands into server, as required by the protocol.
7891 * Removed method function pointers from SilcBuffer structure. They
7892 weren't used to anything and just increased the context size for
7893 no good reason. This change also made silc_buffer_alloc and
7894 silc_buffer_free functions inline functions.
7896 * Disabled command flooding detection support until it's fixed so
7897 that it accepts commands in but does not execute them more than once
7900 * Added silc_net_localhost(), to return local hostname, into
7901 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7902 that must be initialized before calling silc_client_init.
7904 * Added new function: silc_server_send_notify_on_channels to send
7905 notify messages to all channels client has joined. It is assured
7906 that the message is sent only once per client.
7908 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7909 lib/silcutil/silcutil.[ch] as silc_format function. The new
7910 function is generic and is used by server as well, not only by
7911 the logging routines.
7913 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7914 the provided version string was not acceptable. Added new function:
7915 silc_ske_check_version into lib/silcske/silcske.h. The function
7916 must be implemented by the application (client or server) and it
7917 does not reside in the SKE library. The function checks the version
7918 string remote end sent.
7920 * Added back pointers (to opaque context and to SilcSocketConnection)
7921 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7923 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7924 duplicate packet context structure.
7926 * Changed `notify' client operation to send same arguments as client
7927 receives from server except for ID's. ID's are mapped to correct
7928 ID entry and that is returned. Also, if channel entry is not sent
7929 by server but the notify is for channel the channel entry is sent
7930 to application (otherwise application doesn't know that it is for
7931 channel (library gets it from packet's Destination ID)).
7933 * Added silc_client_remove_from_channels into client library to
7934 remove a client from all channels it has joined to. Used when
7935 received SIGNOFF notify from server. Added also new function
7936 silc_client_replace_from_channels to replace old ID entry with
7937 new ID entry on all channels. Used when received NICK_CHANGE
7940 * Fixed ID Cache list handling in silc_idlist_get_client in
7941 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7942 to get (or query) client by ID.
7944 * Updated TODO list.
7946 * Added connection authentication status message defined by the
7947 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7948 support for these into the code in client and server side.
7950 * Added generic function silc_client_send_command to send any command
7951 with variable argument list. Application should use this function
7952 to send commands if the command functions provided by the library
7953 does not suite for the application's user interface needs.
7955 * Added new `failure' client operation. Application is notified about
7956 received failure packet if client is executing a protocol. In this
7957 case the protocol's execution has failed.
7959 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7960 is required by the protocol.
7962 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7963 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7966 * Added status flag to SilcSKE object to indicate realtime status
7967 of the SKE protocol.
7969 * Application receives now exactly same command reply arguments as
7970 the library receives from server. However, if ID is received the
7971 corresponding ID entry is returned to the application (eg. Client
7972 ID is mapped to correct SilcClientEntry entry and that is returned).
7973 Changed command_reply client operation due to this change.
7975 * Changed all ID's in commands and in command replys as ID Payloads.
7976 Change affected both client and server side codes.
7978 All ID's sent in SILC network (with execption of ID's in SILC
7979 Packet header) are sent in ID Payload to support variable length
7982 * Server now notifies nick changes and notifies all clients on
7983 the channels about the new nickname (about the new Client ID,
7986 * Implemented CMODE command to change channel modes. Supports all
7987 channel modes defined by the protocol specs except ban and invite
7988 lists. (Also, private channel key mode is supported but support for
7989 setting private channel key in client is missing, thus, this mode
7990 has no effect on client side (except that server requires that the
7991 client uses private channel key and normal channel traffic does not
7994 Also, invite mode works per se, but INVITE command does not work
7995 yet correctly, so you can set channel as invite only channel but
7996 inviting clients to the channel does not work (it is yet to be
7997 thought what's the best way to do it).
7999 * Added new command SILC_COMMAND_CUMODE to change user mode on the
8000 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
8001 Implemented CUMODE command to change user's mode on the channel.
8002 Supports all modes defined by the protocol specs.
8004 * Added NAMES command reply to return users modes on the channel.
8006 * Removed unnecessary and slow ciphers from lib/silccrypt.
8008 * Set SO_KEEPALIVE option to connection sockets by default.
8010 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
8012 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
8013 redefined the Notify Payload into protocol specs.
8015 * Added silc_id_payload_parse_id to get ID directly from raw
8018 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8020 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
8021 accept searching by Client ID as well.
8023 * Added support for LEAVE and SIGNOFF notify types in client library.
8025 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
8026 to parse ID Payload from raw data.
8028 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8030 * Added flags parameter into silc_ske_assemble_security_properties
8031 function in lib/silcske/silcske.[ch].
8033 * Changed notify client operation to fit better for notify messages
8034 sent by server. The notify payload received from server is now
8035 passed to the application (after parsing it to SilcNotifyPayload).
8036 It is application's responsibility to retrieve the arguments
8037 from the payload and show the message the way it wants. The message
8038 sent by server is implementation specific.
8040 * Changed public keys to comply with the protocol specification.
8041 Old public keys are not supported anymore and are not compatible.
8043 * Removed nickname from Channel Payload as the latest draft removed
8044 it. The client must resolve the nickname from the NAMES command
8045 reply received when it joined the channel.
8047 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
8049 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8051 * Fixed some errors in protocol specification drafts.
8053 * Created lib/silccore/silcnotify.c to implement Notify Payload
8054 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
8055 generic payloads described by protocol specifications. The file
8056 includes implementations for ID Payload and Argument Payload.
8058 * Changed Command Payload implementation to use the new Argument
8059 Payload. Changed command_xxxx_payload to command_payload_xxxx
8060 to comply with SILC coding conventions.
8062 * Added suppport for Argument Payload handling in Notify Payload
8063 implementation as protocol requires it. Added the new support
8064 into server and client lib as well.
8066 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8068 * Added support for multiple nicknames on same channel. [n] is
8069 added locally to the nickname if there are more than one same
8070 nicknames on the channel.
8072 * Server now sends all nicknames that matched WHOIS request.
8073 Client also shows the list received from server.
8075 * Added TOPIC command to client side. User can now set and show
8076 current topic on channel.
8078 * Added MOTD command to client and server. Also, server sends the
8079 motd when client connects to the server.
8081 * Changed version strings to comply ISO 8601.
8083 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8085 * Fixed protocol error handling in client library. It should now
8086 cope even if the SKE fails for some reason.
8088 * Made new protocol specification drafts for submitting to IETF.
8090 * Implemented TOPIC command to server in silcd/command.c.
8092 * Added two new notify types into lib/silccore/silcnotify.h:
8093 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
8094 notify nickname change and topic setting/change on a channel.
8096 * API change of command_reply operation in client library. The
8097 application gets now the status type received from server as well.
8099 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8101 * Removed the function just added to lib/silcutil/silcschedule.[ch].
8103 * Cras fixed and optimized the packet handling even further and
8104 it should work now. Minor change to the prototype of function
8105 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
8107 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8109 * Added new function into lib/silcutil/silcschedule.[ch]:
8110 silc_schedule_with_fd to select() a specified fd. The function
8111 returns after timeout expires or data arrives or goes. The
8112 function is used by packet routines to wait that all data is
8113 received from network.
8115 * Fixed data reading from network in lib/silccore/silcpacket.c.
8116 The code now assures that all data is read from the fd and then
8117 continues packet processing. This was a bug fix since the code
8118 used to drop some data in some circumstances.
8120 * Added new function into lib/silcclient/client.[ch]:
8121 silc_client_start_key_exchange to start key exchange after
8122 connection has been established to server. The code internally
8123 now uses this funtion but its main purpose was to provide it
8124 for applications that perform their own connecting. After
8125 application has created a connection it merely calls this
8126 function to start the key exchange between client and server.
8127 The library takes care of everything else after that.
8129 Updated also lib/silcclient/README to explain the usage of
8132 * Do not send to application information that connection has
8133 been established. Application gets notified it by connect
8136 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8138 * Applied cras's patch to add silc_schedule_one function. The
8139 function runs scheduler once and returns.
8141 * Fixed the scheduler after cras messed it up. The timeout
8142 handling works now as it's supposed to work.
8144 * Added into lib/silccore/ silcnotify.h to include notify
8145 message types support. Changed silc_server_send_notify*
8146 functions, in server.[ch], to support those new notify types.
8147 Added the support for the notify types into client library,
8148 as well. Added new notify client operation into ops.h in
8151 * Changed silc_server_packet_send_to_channel to send normal
8152 packets instead of just channel message packets. The function
8153 is now used to send the notify packets to channels. It is not
8154 used to send channel message packets anymore, as server never
8157 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
8158 va_arg()s as it seems to require it nowadays. I guess, if SILC
8159 is compiled with older va_arg() the new code should work anyway.
8161 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8163 * Splitted core library. Core library (lib/silccore) includes
8164 now only SILC protocol specific core (and common) components.
8165 Created new utility library (lib/silcutil) that includes more
8166 generic purpose stuff. The stuff for util library was taken
8167 from the old core library. This was minor and easy split.
8169 * Created SILC Client Library (lib/silcclient) that includes
8170 implementation of the SILC client without user interface. This
8171 was major move from silc/ directory. The code has been changed
8172 so that it is transparent towards the user interface. The
8173 silc/ directory includes now the same user interface as before
8174 and it uses the new client library. Read lib/silcclient/README.
8175 Basicly, the client library performs everything else related
8176 to SILC except user interface handling. Also, configuration
8177 files are considered to be part of user interface and library
8178 does not handle them.
8180 This change also changed a lot of structures, function naming etc.
8181 Most important change was that SilcClientWindow object was
8182 renamed to SilcClientConnection in the client library. Created
8183 also new file lib/silcclient/ops.h. Also added new files
8184 silc/local_command.[ch] and silc/client_ops.[ch].
8186 All these changes were made to make it easier for user interface
8187 designers to create what ever user interface for the SILC client
8190 It is also expected that the server will be moved to lib
8191 directory as well and SILC Server Library will be created;
8192 sometimes in the future.
8194 * Removed Local commands from lib/silccore/silccommand.h as
8195 they are application specific and new client library does not
8196 handle any of those anymore.
8198 * Several functions moved to lib/silcutil/silcutilc.[ch] from
8199 old client implementation in silc/.
8201 * Added support for callback functions in SILC_LOG_* macros.
8202 Application can now set its own callbacks that will be called
8203 instead of using the default functions that will always print
8204 the debug messages to stderr (or stdout). Also, debugging can
8205 now be disabled by setting silc_debug to FALSE and re-enabled by
8206 setting it to TRUE. Note, that logging will still work even
8207 if debugging is disabled.
8209 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
8210 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
8211 silc_log_reset_debug_callbacks.
8213 * To enable debugging in silc client one must give now -d
8214 option on command line.
8216 * Changed silc_schedule_init to automatically allocate task queues
8217 if they are not allocated before calling it.
8219 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8221 * Added GMP 3.1 into math library.
8223 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8225 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
8226 a channel in SILC network. The packet is used by servers and
8227 routers to notify other routers that user has left a channel.
8228 This little feature was missing until now. Added the feature
8229 to protocol specification as well.
8231 Added functions: silc_server_send_remove_channel_user and
8232 silc_server_remove_channel_user into server.[ch].
8234 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
8235 lib/silccore/silcpacket.h. However, they are not implemented
8238 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8240 * Fixed joining to a channel and sending channel messages
8241 between server and router. The channel message sending should
8242 now work inside a cell.
8244 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8246 * Fixed the private message sending between server and router.
8247 The private message sending should now work inside a cell.
8249 * Added silc_server_replace_id into server.[ch] to replace
8250 existing ID in the SILC network.
8252 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
8253 and silc_idlist_replace_server_id into idlist.[ch] in server.
8255 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8257 * Fixed the server to server connections. Server can again now
8258 connect to router. Router to router connections probably does
8261 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8263 * Added dynamic protocol registering support. Now protocols can
8264 registered and unregistered on the fly. Patch by cras.
8266 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8268 * Added lib/contrib directory to hold routines that some platforms
8269 don't have but are needed by SILC.
8271 * Added getopt.c, getopt1.c and getopt.h from GNU C library
8272 into lin/contrib to provide getopt() and getopt_long() for
8273 those who don't have it.
8275 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8277 * Added AWAY command to client. When away message is set and
8278 client receives a private message packet the client automatically
8279 replies to the sender with the away message.
8281 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
8282 bug seemed to be the cause of recent problems when compiling
8285 * Added version detection support to SKE protocol specification
8286 and added the new changes to the SKE implementation as well.
8287 There were other minor changes in the SKE protocol as well.
8289 Many changes in lib/silcske/silcske.[ch] and in
8290 lib/silcske/payload.[ch].
8292 * Added ^U functionality, clear input line. Patch from cras.
8294 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8296 * Mainly small bugfixes on core library. Fixed some debugging
8297 logging and buffer overflow in silclog.c.
8299 * Updated config.sub and config.guess on the distribution tree.
8301 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8303 * Added command lagging support in server. Client may execute
8304 commands now only once in two seconds.
8306 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8308 * Optimized packet reception. MAC computation and checking is now
8309 also more optimized. A lot previously duplicated code is now
8310 used as generic by both client and server.
8312 * Fixed key pair generation in clientutil.c
8314 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8316 * Added into lib/silccore/silcbufutil.[ch] new function;
8317 silc_buffer_realloc.
8319 * Moved generic packet sending/encryption functions to
8320 lib/silccore/silcpacket.[ch] from client and server. Some
8321 rewriting of the functions.
8323 * Moved all generic packet reception/decryption functions to
8324 lib/silccore/silcpacket.[ch] from client and server. The
8325 packet processing is now much cleaner in both client and server.
8326 These were major changes in both client and server.
8328 * Created many common functions in server to do packet sending.
8329 Previously code were duplicated a lot, this has been removed
8332 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8334 * Rewrote major parts of the ID cache system. Don't know
8335 whether it is better now or not but at least the API is more
8338 * Major rewrite on ID cache stuff on client because of the ID
8339 cache API changes. Added idlist.c to client.
8341 * Also major rewrite on ID cache stuff on server as well.
8342 Major rewrite of idlist.[ch]. SilcXXXList's are now named
8343 SilcXXXEntry's. We won't keep anymore idlist specific pointers
8344 in hand, instead they are all put into the ID cache system now.
8345 All server_idlist_* routines uses ID cache now instead of
8346 traversing its own lists (those lists does not exist anymore).
8347 SilcIDList though still exists. Also, SilcXXXEntry's are
8350 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8352 * Finally made the SKE implementation compliant to the protocol
8353 specification. All mp integers are now binary encoded as
8354 opposed being HEX encoded.
8356 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
8359 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
8360 functions: silc_[encode/decode]_pem. Also added function
8361 silc_encode_pem_file to PEM encode with newlines ('\n') for
8364 * SILC public keys are now encoded either PEM or binary. Same
8365 option is for private keys as well. By default private keys
8366 are binary encoded and public keys PEM encoded. Silly HEX
8367 encoding were removed.
8369 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
8370 function to create fingerprints.
8372 * Fixed a bug in SHA1; does not change the original data anymore.
8374 * Partly implemented INFO command on client and server side.
8375 Fixed CLEAR command. Changes to SERVER command; show current
8376 server(s) when giving command without arguments. Added
8377 VERSION command to client.
8379 * Added check to server that unregistered connections cannot
8380 execute commands (unless it is specificly allowed).
8382 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8384 * Fixed screen refresh.
8386 * Fixed channel joining bug from client. On some circumstances
8387 client tried to join to a channel it had already joined.
8389 * Added public key verification process into client's protocol.c.
8390 The client now verifies the public key from user and saves
8391 it into ~./silc/serverkeys/ directory.
8393 Added into: clientutil.[ch]: silc_client_verify_server_key.
8395 * Changed SKE protocol's silc_ske_initiator_finish function
8396 to accept callback function that verifies the received public
8397 key. Removed old silc_ske_verify_public_key function.
8399 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8401 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
8402 silc_pkcs_private_key[_data]_set.
8404 * Made the password and public authentication more cleaner in
8405 server's protocol.c.
8407 * Removed historic and obsolete protocol `channel_auth' from
8408 both client and server.
8410 * Removed wrong way of sending command status messages from
8411 server to client in server's command.c. The old way violated
8412 protocol specification.
8414 Changes to silccore/silccommand.[ch]: removed
8415 silc_command_encode_status_payload -> not needed anymore,
8416 changed silc_command_encode_payload_va to accept extra
8417 argument on variable argument list. The argument type must
8418 now be provided to the function. Also, added new function:
8419 silc_command_encode_reply_payload_va which is same as
8420 normal command_encode_payload_va except command status type
8421 is provided as extra argument.
8423 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8425 * Added ~./silc directory handling. The directory includes the
8426 public and private keys for the client.
8428 Added silc_client_check_silc_dir, silc_client_create_identifier
8429 and silc_client_load_keys.
8431 * Implemented SILC protocol compliant public key. Added public
8432 and private key saving to and loading from files.
8434 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
8435 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
8436 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
8437 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
8438 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
8440 Implemented: silc_pkcs_save_[public/private]_key[_data] and
8441 silc_pkcs_load_[public/private]_key.
8443 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8445 * Added silc_server_get_route (route.[ch]) to get connection
8446 data for the fastest route for given ID.
8448 * Implemented INVITE command on client and server. The command
8449 were re-defined in the SILC Protocol Specification and the
8450 implementation now complies with the specification.
8452 * Implemented PING command on client and server.
8454 * Implemented NAMES command on client and server. The server side
8455 supports currently only normal server not router server yet.
8456 Some changes to NAMES definition in SILC protocol specification.
8458 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8460 * Implemented LEAVE command on client and server.
8462 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
8463 again. This change was made to the protocol as well. Server
8464 should not violate the protocol specification anymore.
8466 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8468 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
8469 was tested. SOCKS4 was not but should work anyway.
