521 these to the client and server. Defined also that other
522 passphrases sent in the protocol MUST be UTF-8 encoded.
523 Affected files are lib/silcske/silcske.c,
524 lib/silcclient/protocol.c, silcd/protocol.c,
525 silcd/serverconfig.c, and lib/silccore/silcauth.c.
527 * Changed the silc_client_close_connection interface to not
528 need the SilcSocketConnection which should not be visible
529 to application. Affected files are lib/silcclient/client.c
530 and lib/silcclient/silcclient.h.
532 * Rewrote the text for Private Message Key Payload in the
533 protocol specification. Protocol TODO #11.
535 Wed Apr 3 16:24:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
537 * Upgraded the protocol version to 1.1, updated protocol specs
540 * Added the nickname as new argument to NICK_CHANGE notify and
541 added it to protocol specs and implemented it to client and
542 server. Protocol TODO #3. Affected files are silcd/idlist.[ch],
543 silcd/command.c, silcd/packet_receive.c, packet_send.[ch], and
544 lib/silcclient/client_notify.c.
546 * Added the killer's client ID to the KILLED notify and added
547 it to protocol specs and implemented it to client and server.
548 Protocol TODO #13. Affected files are silcd/command.c,
549 silcd/packet_receive.c, packet_send.[ch],
550 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
551 The killer's client entry is now returned to application in
552 the `notify' client operation.
554 * Fixed the Max Argument fields that had too large value set
555 in the protocol specs. Protocol TODO #14.
557 * Added the LEAVE command reply to return the ID of parted
558 channel. Updated protocol specs and implemented it to the
559 client and server. Protocol TODO #15. Affected files are
560 silcd/command.c, lib/silcclient/command_reply.c. The channel
561 entry is now returned to application in the `command_reply'
564 * Rewrote the version SKE version checking in client libary
565 and in server to use the silc_parse_version_string. Affected
566 files are lib/silcclient/protocol.c, silcd/protocol.c.
568 * Added SILC_STATUS_ERR_NO_CHANNEL_FOPRIV error status to few
569 commands that was missing it, and updated protocol specs and
570 the server implementation. Protocol TODO #10. The affected
571 file is silcd/command.c.
573 * Defined new message flags SILC_MESSAGE_FLAG_REPLY to be
574 generic reply to a generic request (REQUEST flag), and
575 SILC_MESSAGE_FLAG_DATA to send any kind of data in a generic
576 way. A draft-riikonen-silc-flags-payloads-00.txt is written
577 to define the payload for DATA flag. Added the flags to
578 the implementation. Protocol TODO #9. Affected file is
579 lib/silccore/silcchannel.h.
581 Changed the client library to return the message length
582 to application as well in the channel_message and private_message
583 client operations. Affected files are
584 lib/silcclient/client_prvmsg, lib/silcclient/client_channel.c,
585 lib/silcclient/silcclient.h, irssi/src/silc/core/client_ops.c,
586 and lib/silcclient/client_ops_example.c.
588 * Added two new channel modes: SILC_CMODE_SILENCE_USERS
589 and SILC_CMODE_SILENCE_OPERS which can be used to moderate
590 the channel. Updated protocol specs and impelemented this
591 to client and server. Protocol TODO #6. Affected files are
592 silcd/packet_receive.c, server_util.c, lib/silcclient/command.c,
593 lib/silcclient/client_channel.c, lib/silccore/silcmode.h.
595 Added new options m and M to CMODE command in Irssi SILC
596 client to set these modes.
598 * Deprecated all administrative commands from SILC protocol
599 since they are highly implementation specific commands.
600 Updated protocol specs. Moved the old commands in
601 implementations to private range of command types. Affected
602 files are silcd/command.c, lib/silcclient/command.c and
603 lib/silcclient/command_reply.c. Protocol TODO #8.
605 * Fixed a bug in server where sending unknown command crashes
606 the server. Affected file silcd/command.c.
608 Wed Apr 3 09:57:47 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
610 * Added SILC_PROTOCOLVERSION macro to check protocol version
611 of a socket connection. The affected file is
612 lib/silcutil/silcsockconn.h.
614 * Added better error logging in rekey protocol. Affected file
617 * Do not check public key types in SKE during rekey. Affected
618 file lib/silcske/payload.c.
620 * Fixed the rekey protocol with PFS, which was totally broken.
621 Affected file silcd/protocol.c.
623 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
625 * Some client implementations quit network by doing first LEAVE
626 and then immediately SIGNOFF (like Bombyx). We now do check
627 after a short time after LEAVE notify and check whether the
628 client is still valid after LEAVE, and if not we remove it from
629 cache. Affected file is lib/silcclient/client_notify.c.
631 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
633 * Merged version 1.1.4 of zlib. Even if it not currently in use,
634 it's good not to have security holes here.
636 * Fixed a negative refcount situtuation for the config context.
637 Affected file is silcd/serverconfig.c.
639 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
641 * ROBOdoc documented lib/silcutil/silcutil.h.
643 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
645 * Optimized even more the SilcPacketContext structure. Now
646 totally saved 16 bytes of memory per context after optimization.
647 Affected files are lib/silccore/silcpacket.[ch].
649 * Made strict checks for valid SILC IDs. Affected file is
650 lib/silccore/silcid.c.
652 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
654 * Changed the object argument for silc_cipher_register,
655 silc_hash_register, silc_hmac_register and silc_pkcs_register
656 to const. Affected files are lib/silccrypt/silccipher.[ch],
657 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
659 * Changed the silc_get_username and silc_get_real_name to
660 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
662 * Fixed the Irssi SILC Client to use the silc_get_username and
663 silc_get_real_name insted of glib routines since the glib
664 routines only corrupt stack. Fixes the Irssi SILC to work in
665 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
667 * Fixed the Irssi to not use g_get_home_dir since it crashes
668 or returns garbage on cygwin and corrupts stack. Added function
669 get_home_dir to Irssi routines. Affected files are
670 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
672 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
674 * Made some structure optimizations. SFTP memory FS MemFSEntry
675 entry structure. Optimized SilcTask structure. Optimized
676 SilcPacketContext structure.
678 Affected files lib/silcsftp/sftp_fs_memory.c,
679 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
681 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
683 * And yet again reverted back the config thing since Johnny
684 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
687 * Fixed memory leaks from config object. Affected files are
688 silcd/serverconfig.[ch].
690 * Added support for adding new connections to the server in rehash.
691 After rehash they take effect.
693 Added support for changing the maximum allowed connections in
694 rehash. The number can grow but going smaller is not supported.
696 Added function silc_server_num_sockets_by_remote to the
697 silcd/server_util.[ch].
699 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
701 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
703 * Added preliminary checking during config parsing for a valid
704 public/private key and removed further checks in the code.
705 Affected files are silcd/serverconfig.[ch], server.c.
707 * Moved functions silc_server_drop() and silc_server_daemonise()
708 from server.c to silcd.c since they are stricly related to
709 the application activity.
711 * Reverted a small part of the automatic ref/unref since
712 it caused a double unref in some situations. Affected
713 files are silcd/silcd.[ch], server.c, serverconfig.c.
715 * Added some .cvsignore files in the lib directory.
717 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
719 * Fixed silc_net_gethostbyaddr to correctly resolve by
720 address. Affected file lib/silcutil/silcnet.c.
722 * Fixed the notify relaying to client. The HMAC to be used
723 with relayed packets ws wrong and caused decryption failure
724 at the client end. Affected file is silcd/packet_receive.c.
726 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
728 * Created new branch silc_protocol_1_0_branch.
730 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
732 * Changed the silc_server_config_* routines to be SilcServer
733 independent. They are now officially application specific code
734 and not part of generic server implementation. Affected files
735 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
737 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
739 * Added automatic referencing of config context in the
740 silc_server_config_alloc, and automatic unreferencing in the
741 silc_server_config_destroy. Affected files are
742 silcd/serverconfig.[ch], silcd/silcd.c.
744 * Fixed the silc_log_quick handling in the logging routines.
745 It didn't log quickly when it was TRUE. Affected file is
746 lib/silcutil/silclog.c. Also the flush delay was set even
747 if it was 0 in config file. Affected file is
748 silcd/serverconfig.c.
750 * Added support for changing key pair of the server in rehash.
751 Affected file silcd/server.c.
753 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
755 * Fixed the TOPIC_SET notify to not cras. It changed the topic
756 too early, before getting the channel entry. Affected file
757 is silcd/packet_receive.c.
759 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
761 * Added functions silc_server_config_[ref/unref], these are used
762 to prevent that the config object is destroyed.
764 No longer directly affect global variables silc_log_quick and
765 silc_log_delay, they are first cached inside the config object
766 and then applied with silc_server_config_setlogfiles().
768 silc_server_config_set_defaults() is now internal to
769 serverconfig.c, there are no reasons to show this internal stuff
772 Affected files are silcd/serverconfig.[ch].
774 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
775 fprintf's to stderr, since some code may be executed again after
776 the server went into the background. Affected files are
779 * Added rehash support. Added function silc_server_rehash() that
780 will perform all the basic tasks of the rehashing procedure.
782 * Added command line option `-x, --hexdump'. This will enable the
783 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
784 The option `--hexdump' implies `--debug'.
786 * Fixed a bad bug in the logging APIs (silcutil library) where
787 the application would crash after calling silc_log_reset_all().
789 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
791 * Fixed the KICKED notify handling in client library to
792 correctly remove the channel and all entries from the
793 channel when I was kicked. This bug crashed the client.
795 Fixed yet another but in KICKED notify handling to remove
796 the kicked client correctly from the channel.
798 Affected file is lib/silcclient/client_notify.c.
800 * Fixed a minor bug in looking up correct client entry
801 in KICKED notify in server. Affected file is
802 silcd/packet_receive.c.
804 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
805 sources correctly to distribution. Fixes --with-gmp option.
807 * Removed the manual rehashing from ID Cache, and changed it
808 to use the SILC Hash Table's auto rehash feature. Affected
809 file is lib/silccore/silcidcache.c.
811 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
813 * Fixed a bug in the silc_client_nickname_format function that
814 handles the multiple same nickname formatting. Two clients
815 with same nickname caused problems after the first one left
816 and rejoined. It didn't format the nickname correctly.
817 Affected file is lib/silcclient/idlist.c.
819 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
821 * Don't change the topic if olod topic is same as new one.
822 Affected file is silcd/packet_receive.c.
824 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
826 * Added cross-reference support to the SILC Documentation
827 generator. All types across all HTML files are now cross-
828 referenced. Affected files util/robodoc/generator.c and
829 scripts/silcdoc/silcdoc.
831 * Added file lib/silcutil/silctypes.h to include all the
832 arithmetic type definitions and some macros. Removed
833 includes/bitmove.h and moved macros to silctypes.h.
835 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
837 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
839 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
841 * Added `type' argument to silc_id_payload_parse_id function which
842 now returns the type of the ID to the sent pointer. Affected
843 file is lib/silccore/silcid.[ch].
845 * Added check for CMODE_CHANGE notify type that mode change is
846 allowed by the sender. Affected file silcd/packet_receive.c.
848 * Added check for CUMODE_CHANGE notify type that mode change is
849 allowed by the sender. Affected file silcd/packet_receive.c.
850 Added the ID type as CUMODE_CHANGE notify type as argument
851 to the `notify' client operation. Affected files are
852 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
854 * Added function silc_client_add_server to the client library.
855 Added support for resolving also channel and server info when
856 received unknown entity in notify packet. Affected files are
857 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
859 * Added function silc_command_get_status to return the command
860 status from the command reply's argument payload. Affected files
861 are lib/silccore/silccommand.[ch].
863 * Added check for KICKED notify type that the kicking is
864 allowed by the client. Affected file silcd/packet_receive.c.
866 * Created function silc_get_input which can be used to get input
867 (echo on or off) from user on command line. Affected files are
868 lib/silcutil/silcutil.[ch].
870 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
872 * Optimized silc_server_packet_relay_to_channel function.
873 Added new function silc_channel_message_payload_encrypt which
874 can be called directly if channel message payload needs to
875 be encrypted and is already encoded (no need to call _encode
876 function). Packet relaying is now done by router without any
877 extra memory allocations. Affected files are
878 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
881 * Fixed the INVITE notify handling. It took wrong arguments
882 as invite list and invite delete. Affected file is
883 silcd/packet_receive.c.
885 * Added check for TOPIC_SET notify type that the topic change is
886 allowed by the client. Affected file silcd/packet_receive.c.
888 * Added check for INVITE notify type that inviting is allowed by
889 the client. Affected file silcd/packet_receive.c.
891 * Changed the silc_server_client_on_channel to return the
892 SilcChannelClientEntry as well. Moved the function
893 silc_server_check_cmode_rights to server_util.[ch].
894 Affected files are silcd/server_util.[ch], silcd/command.c.
896 * Added function silc_server_check_umode_rights to check whether
897 changing client's user mode is allowed. Added check for
898 UMODE_CHANGE notify type that the umode change is allowed
899 by the client. Affected files are silcd/server_util.[ch],
900 silcd/packet_receive.c and silcd/command.c.
902 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
904 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
905 ID length. It ignored that ID can be IPv6 based as well.
906 Affected file lib/silccore/silcpacket.h.
908 * Fixed the silc_id_id2str and silc_id_str2id to take the
909 IPv6 address offset's into consideration. Affecte file is
910 lib/silccore/silcid.c.
912 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
914 * Fixed the internal Unix scheduler functions to check for
915 NULL context they may receive. The affected file is
916 lib/silcutil/unix/silcunixschedule.c.
918 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
920 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
921 can specify different directory with --home command line
922 parameter. Affected files irssi/src/silc/core/client_ops.c,
925 * SILC-specific commands aren't now executed if the active server
926 isn't of SILC-type, so there won't be problems with having
927 IRC and SILC protocol support in same client. Affected files
928 irssi/src/silc/core/silc-channels.c, silc-servers.c,
931 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
933 * Improved the signal support in SILC Schedule. Added new
934 function silc_schedule_signal_call which is used by application
935 to mark a signal to be called. It is now safe to perform
936 any kind of tasks in signal callbacks since it is guaranteed
937 that the application specified signal callback is called
938 after the signal is over. Affected files are
939 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
941 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
943 * Added `name' field to SilcChannelPrivateKey to represent
944 application given name for the key. Moved also the context from
945 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
946 Added the `name' argument also to the function
947 silc_client_add_channel_private_key.
949 Added function silc_client_current_channel_private_key to set the
950 current channel private key in use.
952 Added "change" command to KEY command which can be used to change
953 the current channel private key. Bound the command also to
956 Also affected files lib/silcclient/client_channel.c,
957 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
959 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
961 * Added silc_rng_get_byte_fast function in to the
962 lib/silccrypt/silcrng.[ch].
964 * Changed the interface of silc_packet_assemble and the
965 silc_packet_send_prepare. If silc_packet_assmble is now
966 called the application does not call silc_packet_send_prepare
967 because the library will call it automatically. These
968 interfaces now also return a reference to the outgoing buffer
969 which includes the assembled packet, which the application can
970 use to encrypt the packet.
972 Affected files are lib/silccore/silcpacket.[ch],
973 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
974 silcd/packet_send.c, server_backup.c and packet_receive.c.
976 * Fixed a packet sending bug on very high load, where outgoing
977 packet queue wasn't handled correctly and packets got corrupted.
978 Affected files are lib/silcutil/*/silc*sockconn.c,
979 lib/silcclient/client.c and silcd/server.c.
981 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
983 * Added macro SILC_PACKET_DATALEN which can be used during
984 packet assembling to check whether the data to be added to
985 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
986 len is truncated until it fits it.
988 Added checks for maximum length of channel message payload and
989 private message payload also.
991 Added checks for maximum packet length in server and in
994 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
995 lib/silcclient/client.c, lib/silccore/silcchannel.c and
996 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
997 lib/silcclient/client_prvmsg.c.
999 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1001 * Added silc_server_packet_queue_purge call to the
1002 silc_server_disconnect_remote to assure that all data in the
1003 queue before disconnecting is sent to the network. Affected
1004 file silcd/server.c.
1006 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1008 * Added the deleting of server's own ID cache entry to the
1009 silc_server_free function. Free also everything else that
1010 has been allocated in silc_server_init. The affected file
1013 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1015 * Added functions silc_parse_version_string, silc_version_to_num,
1016 and silc_ske_parse_version to parse SILC protocol style version
1017 strings. Affected files lib/silcutil/silcutil.[ch] and
1018 lib/silcske/silcske.[ch].
1020 * Added new configuration params: version_protocol, version_software
1021 and version_software_vendor to specify what version the remote
1022 host must at least be to be able to connect to server. The vendor
1023 string can be regex matched too. Added new function
1024 silc_server_connection_allowed to check maximum number of allowed
1025 connections, and allowed versions for incoming connections.
1026 Affected files are silcd/server.c, server_util.[ch] and
1029 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1031 * Added preliminary support for signals in scheduler. The
1032 signals we care about are now blocked always when the scheduler
1033 is locked. This way we can synchronise the use of signal with
1034 scheduler. It is guaranteed that when signal occurs the scheduler
1035 is not locked, and thus new tasks can be safely added to the
1038 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
1039 to silc_schedule_internal_init and silc_schedule_internal_uninit.
1040 Added new platform specific routines
1041 silc_schedule_internal_signals_[un]block and
1042 silc_schedule_internal_signal_[un]register.
1044 Added new functions to SILC Schedule API:
1045 silc_schedule_signal_[un]register. Each signal that application
1046 is going to use should be registered to the scheduler.
1048 Affected files are lib/silcutil/silcschedule.[ch],
1049 lib/silcutil/*/silc*schedule.c.
1051 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1058 string is 7-bit ASCII string. Affected files are
1059 lib/silcutil/silcutil.[ch].
1061 * Added function silc_id_is_valid_server_id into the
1062 silcd/serverid.c and added checking for valid Server ID's in
1063 silc_server_new_server. The Server ID must always be based
1064 on the server's public IP address.
1066 * Added logging of DISCONNECT packet message in the server.
1067 Affected file silcd/server.c.
1069 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1071 * Changed all library interfaces that use Global RNG to also
1072 accept SilcRng as argument. Affected files are
1073 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
1074 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,

1076 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
1077 lib/silccrypt/rsa.c.
1079 * Added function silc_pkcs_generate_key to the
1080 lib/silccrypt/silcpkcs.[ch] for applications so that they
1081 don't need to do pkcs->pkcs->init calls anymore.
1083 * Remove SilcSocketConnection from the SFTP API since it really
1084 wasn't needed there. The application has the information
1085 saved in its contexts anyway and the SFTP layer doesn't need
1086 know about it. Affected files lib/silcsft/silcsftp.h and
1087 lib/silcsftp/sftp_[server/client].c.
1089 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].

1093 lib/silcutil/silcutil.c.
1095 * On EPOC the global crypto module lists are not used at all
1096 in the crypto library. Added support for using the constant
1097 algorithm list on EPOC. Affected files are
1098 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
1101 * Fixed the handling of third parameter of KICKED notify, since
1102 it was mistakenly updated to SILC Protocol 1.0 even though it
1103 is to be included in 1.1. Since it is not in 1.0 it is not
1104 mandatory, and this fix now handles it only if it is provided,
1105 and it is not error if it is not provided. Affected file
1106 lib/silcclient/client_notify.c.
1108 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1120 file silcd/packet_send.c.
1122 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
1124 * $usermode, $cumode and $cumode_space expandos shouldn't do
1125 anything with non-SILC server records. Affected file
1126 irssi/src/silc/core/silc-expandos.c
1128 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1131 IPv6 bound sockets as well. Now they can return IPv6 addresses
1132 as well. Affected file lib/silcutil/silcnet.c.
1134 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
1135 Affected lib/silcutil/unix/silcunixnet.c.
1137 * Fixed ID rendering (at least on some platforms, not NetBSD)
1138 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
1140 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1142 * Added silc_hash_public_key and silc_hash_public_key_compare
1143 functions to be used with SilcHashTable. They can be used to
1144 hash public keys and compare public keys in hash table. Affected
1145 file lib/silcutil/silcutil.[ch].
1147 * Added support for specifying multiple public keys for Client
1148 connection section in server configuration file. This makes it
1149 possible to accept multiple public keys from same host, or to
1150 make a section that accepts any incoming host, and have the
1151 accepted public keys listed in the section.
1153 Added functions silc_sever_[find/get]_public_key, added the
1154 support for this actually to all connection sections but only
1155 the Client section is currently allowed to specify multiple
1158 Affected files are silcd/server.c, server_internal.h,
1159 command.c, protocol.c, server_util.[ch], packet_receive.c.

1171 Also fixed some documentation typos.
1173 Affected files are lib/silcutil/silclog.[ch].
1175 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1177 * Fixed the server to check correctly the amount of connections
1178 from single host, by checking also the type of the connection.
1179 Fixed also the comparison of number of connections and number
1180 of allowed connections. Affected files are silcd/server.c,
1183 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1185 * Fixed the USERS command reply to save the user's mode on the
1186 channel as well. Fixed JOIN command reply to check whether a
1187 client is on channel already and not join it twice. Affected
1188 file lib/silcclient/command_reply.c.
1190 * Added new file silc-expandos.c into irssi/silc/core/ to return
1191 various stuff for various signal for the statusbar etc. updating.
1192 Now Irssi SILC client prints channel user modes etc. on the
1195 * The user mode (like server/router operator changes) is now shown
1196 on the Irssi SILC client's statusbar. The affected files are
1197 irssi/src/silc/core/client_ops.c, silc-expandos.c.
1199 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1201 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c

1236 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
1237 to avoid collisions with other libraries using same type names
1240 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1242 * Added `prefer_ipv6' argument to the functions
1243 silc_net_gethostbyname[_async]. If it is TRUE it will return
1244 IPv6 address over IPv4. If FALSE IPv4 address is returned
1245 even if IPv6 address was found. Affected files
1246 lib/silcutil/silcnet.[ch].
1248 * Added support silc_net_create_connection[_async] to fallback
1249 to IPv4 address if IPv6 address could not be used (like if

1259 Wed Feb 20 20:41:01 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1261 * Added automatic extern "C" { ... } for C++ compilers so the
1262 application does not need to define them. Affected file
1263 includes/silcincludes.h.
1265 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
1266 old name went against naming convention. Applications now
1267 include "silcclient.h" instead of "clientlibincludes.h".
1268 Removed includes/clientlibincludes.h, it is redundant now.
1270 * Renamed includes/version.h to silcversion.h.
1272 * Added really preliminary support for OS/2 into the util
1273 library. Only thread & mutex API is implemented, others
1274 are still to be implemented. Created the lib/silcutil/os2/
1275 directory. Created also file includes/silcos2.h.
1277 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1308 * Added `user_count' to the SilcChannelEntry which now tells the
1309 number of users on the channel. The user count is now saved
1310 in normal server of global channels as well. Affected files
1311 silcd/server.c, idlist.h, packet_receive.c and command.c.
1313 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
1314 include file utility functions.
1316 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
1317 instead of calling directly OS routines.
1319 * Fixed NICK change printing in Irssi SILC Client. Fixed
1320 KICKED notify printing in Irssi SILC Client. Affected file
1321 irssi/src/silc/core/client_ops.c.

1329 * ROBOdoc documented the lib/silcske/silcske.h, and improved
1330 the SKE interface a bit.
1332 * Fixed padding problem in PKCS#1. The padding was not actually
1333 random since the random number generator was used incorrectly.
1334 This security bug affects only when encrypting with PKCS#1, and
1335 it is not currently used at all in SILC. SILC only use signing
1336 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
1338 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1350 key_exchange_timeout, conn_auth_timeout, connections_max,
1353 Implemented all the new config settings handling in the server.
1355 Optimized the use of SKE Mutual flag usage. Use it only
1356 if connection authentication protocol is not based in public
1359 Renamed all SilcServerConfigSection* to SilcServerConfig*
1360 to have a bit shorter names.
1362 Affected files silcd/serverconfig.[ch], server.[ch], and

1399 Affected files irssi/src/silc/core/silc-core.c,
1400 irssi/src/fe-text/silc.c.
1402 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1404 * Added new configuration options and blocks:
1405 keepalive_secs, reconnect_count, reconnect_interval,
1406 reconnect_interval_max, reconnect_keep_trying and
1407 require_reverser_lookup. Added ConnectionParam block, and
1408 implemented the connection parameters when connecting as
1409 initiator and when accepting connections as responder.
1411 Added CONFIG_IS_DOUBLE macro in config file parsing, to check
1412 whether given configuration value has been given already.
1414 Affected files silcd/serverconfig.[c], server.[c].

1417 algorithm parts and created new file silcalgs.conf, that
1418 is now included from the example_silcd.conf.in.
1420 * Optimized the silc_server_connect_to_router_second to take
1421 the connection configuration object from the SilcServerConnection
1422 object instead of finding it during the connecting phase.
1423 Added the configuration object to SilcServerConnection struct.
1424 Affected files silcd/server_internal.h, server.c.
1426 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1428 * Add the client on channel after it was resolved at the
1429 channel message receiving, and it was not already on the
1430 channel. Affected file lib/silcclient/client_channel.c.
1432 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1448 authentication to be set at the same time.
1450 Added `prefer_passphrase_auth' setting in config file which
1451 can be used to set to prefer passwd auth if both passwd and
1452 public key is set. If not set, public key is preferred.
1453 This has effect only when being initiator (responder will try
1456 Added support for authentication with passphrase and public key
1457 at the same time. The passphrase is tried first always since
1458 it is faster to check.
1460 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
1462 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

1508 * Fixed the file transfer's key agreement payload to include
1509 zero port also if the hostname is NULL because it could not
1512 Call file transfer monitor callback now also if error occurs
1513 during key agreement protocol.
1515 Changed the silc_client_file_send interface to return the
1516 SilcClientFileError instead of session id. The session ID
1517 is returned into pointer provided as argument.

1540 channel key it won't encrypt since the payload is corrupted.
1541 Affected file lib/silccore/silcchannel.c.
1543 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1557 become invalid in the callback but it was referenced after
1558 the callback returned.
1560 Do not allow auto rehashing of hash table during the
1561 silc_hash_table_foreach operation, for same reasons as it is
1562 not allowed for SilcHashTableList. Affected files are
1563 lib/silcutil/silchashtable.[ch].
1565 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1567 * Defined DLLAPI into silcincludes.h and silcwin32.h for
1568 Win32 DLL. extern's in header files are now declared with
1571 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1573 * Fixed private message handling. It used some old code that
1574 caused the client to crash. Affecte file is
1575 lib/silcclient/client_prvmsg.c.
1577 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1579 * Added function silc_client_add_channel,
1580 silc_client_replace_channel_id, and removed functions
1581 silc_client_new_channel_id and silc_idlist_get_channel_by_id
1582 from client library.
1584 * Added cross reference of the joined channels to the
1585 SilcClientEntry, and changed the SilcChannelEntry's
1586 users list to SilcHashTable. The affected files are
1587 lib/silcclient/idlist.[ch].
1589 * Fixed a bug in hash table tarversing. While the hash table
1590 is traversed with SilcHashTableList the table must not be
1591 rehashed. It is now guaranteed that auto rehashable tables
1592 are not rehashed while tarversing the list. Also defined that
1593 silc_hash_table_rehash must not be called while tarversing
1594 the table. Added function silc_hash_table_list_reset that must
1595 be called after the tarversing is over. The affected files are
1596 lib/silcutil/silchashtable.[ch].
1598 * Changed all hash table traversing to call the new
1599 silc_hash_table_list_reset in server and in client library.
1601 * Added function silc_client_on_channel to return the
1602 SilcChannelUser entry if the specified client entry is joined
1603 on the specified channel. This is exported to application as
1604 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
1606 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1608 * Fixed founder regaining problem with JOIN command on normal
1609 server. The notify for mode change must be sent always and
1610 not only if !cmd->pending. Affected file silcd/command.c.
1612 * Fixed the WHOWAS command's reply sending to support the
1613 lists correctly. Affected file silcd/command.c.
1615 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1617 * When sending JOIN command to router for processing the
1618 sender's old command identifier was not saved back to the
1619 sender's command context, fixed now. The affected file is
1622 * Create the key in JOIN command of the router did not return
1623 the channel key, added check for this. Affected file is
1626 * Fixed a channel ID update bug in JOIN command reply. Do
1627 not directly upgrade the ID but call the function
1628 silc_idlist_replace_channel_id if the ID was changed.
1629 Affected file silcd/command_reply.c.
1631 * Fixed memory leaks from command calling if it would fail.
1632 Affected file silcd/command.c.
1634 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1636 * Applied patches from cras:
1638 Memory leak fixes around libaries, irssi window resize fix,
1639 new silclist.h and silcdlist.h, all extern inline changed to
1642 * Removed dotconf from lib/dotconf, not needed anymore.
1644 * Removed TRQ from lib/trq, not needed anymore.
1646 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
1647 with server connections. Later this will be configurable
1648 in config file after new config file is done. Affected file
1651 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1653 * Fixed a crash in server related to channel announcements.
1654 Affected file silcd/server.c.
1656 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1658 * Fixed memory leaks in silc_server_create_new_channel*
1659 functions. Affected file silcd/server.c.
1661 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
1662 which ID was changed. This way the router will send the
1663 user list for the channel again, and server won't be in
1664 desync in some rare circumstances. Affected file is
1665 silcd/packet_receive.c.
1667 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1669 * Check for NULL socket pointer in the function
1670 silc_server_packet_send_to_channel_real. Affected file
1671 silcd/packet_send.c.
1673 * Fixed the BAN notify handling to correctly remove ban
1674 list. Affected file silcd/packet_receive.c.
1676 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1678 * Fixed some header addition to Toolkit distribution in
1679 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
1681 * Added lib/silcclient/client_ops_example.h as an template
1682 file for application programmers to quickly start using
1683 the SilcClientOperation functions in their application.
1684 Updated the lib/silcclient/README as well to tell about this
1685 nice file made available.
1687 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1689 * Call silc_server_remove_from_channels when removing client
1690 entry when NO_SUCH_CLIENT_ID was received. Affected file
1691 is silcd/command_reply.c.
1693 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1695 * Added server & router operator statistics updating. Affected
1696 file silcd/packet_receive.c and silcd/command.c.
1698 * Fixed the SERVER_SIGNOFF notify handling on normal server
1699 not to save the history information for clients. Same was
1700 fixed earlier in remove_clients_by_server function, but not
1701 here. Affected file silcd/packet_receive.c.
1703 * Raised the default connection-retry count from 4 to 7 in
1704 server. Affected file silcd/server.h.
1706 * Cancel any possible reconnect timeouts when we start the
1707 key exchange. Affected file silcd/server.c.
1709 * Do not reconnect on connection failure when SCONNECT was
1710 given. Affected files silcd/server.[ch].
1712 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1714 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
1716 * Fixed the NICK command to always give the unformatted
1717 nickname to the one giving the NICK command. If unformatted
1718 nickname is cached already it will be formatted and the
1719 local entry will always get the unformatted nickname.
1720 Affected file lib/silcclient/idlist.c.
1722 * Fixed some double frees from client library commands.
1723 Affected file is lib/silcclient/command.c.
1725 * Fixed CUMODE command in server to assure that no one can
1726 change founder's mode than the founder itself, there was a
1727 little bug. Affected file silcd/command.c.
1729 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1731 * Removed the SilcClientCommandDestructor from the client
1732 libary, it is not needed anymore. Affected files are
1733 lib/silcclient/silcapi.h, command[_reply].[ch],
1734 client_notify, idlist.c.
1736 * Fixed GETKEY command to first resolve client, and then
1737 resolve the server only if the client was not found, instead
1738 of resolving both at the same time. Affected file is
1739 lib/silcclient/command.c.
1741 * Added silc_client_start_key_exchange_cb and lookup the
1742 remote hostname and IP address before starting the key
1743 exchange with server. The affected file is
1744 lib/silcclient/client.c.
1746 * The server's public key is now saved using the IP address
1747 of the server and not the servername for the filename.
1748 The hostname public key filename is checked as an fall back
1749 method if the IP address based filename is not found.
1751 Fixed the GETKEY command to save the fetched server key
1752 in correct filename.
1754 Print the remote server's hostname now when new key is
1755 received during connection process. Affected file is
1756 irssi/src/silc/core/client_ops.c.
1758 * Return always our own public key to the client if it asks
1759 for it with GETKEY command. Affected file silcd/command.c.
1761 * Removed the use_auto_addr variable from default config
1762 file since it was in wrong section. Affected file is
1765 * Fixed TOPIC_CHANGE notification to not route it when it
1766 was sent using silc_server_send_notify_to_channel function.
1767 Affected file silcd/command.c.
1769 * Fixed silc_server_send_notify_kicked to send the kicker's
1770 Client ID also, it was missing. Affected files are
1771 silcd/command.c, silcd/packet_send.[ch].
1773 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1775 * Do not save client history information in SERVER_SIGNOFF.
1776 Fixes the bug in normal server that it does not detect
1777 the client becoming valid after the server becomes back
1778 online. Affected file silcd/server_util.c.
1780 * Added `sock_error' field into the SilcSocketConnection
1781 context. When error occurs during socket operation (read
1782 or write) the error is saved. Added also new function
1783 silc_socket_get_error to return human readable socket error
1784 message. Affected files are lib/silcutil/silcsockconn.[ch],
1785 lib/silcutil/unix/silcunixsockconn.c, and
1786 lib/silcutil/win32/silcwin32sockconn.c.
1788 * The server now prints the socket error message in the
1789 signoff for client. Affected file silcd/server.c.
1791 * Fixed the `created' channel information sending from router
1792 to server in JOIN command. Checks now whether the channel
1793 really was created or not and set it according that.
1795 Fixed the JOIN command to use the client entry's current
1796 ID during the joining procedure instead of the one it sent
1797 in the command (it is checked though), since it can change
1798 between the packet processing and command processing, and
1799 would just case unnecessary pain in the client end. Affected
1800 file silcd/command.c.
1802 * Fixed a channel key payload sending to use correct channel
1803 ID when the server was forced to change the channel's ID by
1804 router. Router sent the key payload with the old Channel ID.
1805 Affected file silcd/packet_receive.c.
1807 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1809 * Call silc_server_save_channel_key only if the key payload
1810 was provided in the JOIN command's command reply. Affected
1811 file silcd/command_reply.c.
1813 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1815 * Fixed silc_mp_sizeinbase to return the value correctly with
1816 MPI. Affected file lib/silcmath/mp_mpi.c.
1818 * Fixed the stop_server signal to correctly stop the scheduler
1819 and gracefully stop the server when SIGTERM or SIGINT signals
1820 are received. Affected file silcd/silcd.c.
1822 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1824 * Simple handling of TERM and HUP signals. Also added some log
1825 flushing call around. Affected file is
1828 * Fixed small bugs in silclog.c. Now buffering output will take
1829 effect after 10 seconds since startup: This will ensure that
1830 no important startup messages are lost. Also output redirection
1831 will preserve original format ([Date] [Type] message).
1832 Affected file is lib/silcutil/silclog.c.
1834 * Added two options to the config file, in the logging section:
1835 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1836 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1838 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1840 * Do not print the warning about log files not being initialized
1841 more than once to avoid excess logging. Affected file is
1842 lib/silcutil/silclog.c.
1844 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1845 the SIM copying in make install in Makefile.am.pre.
1847 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1849 * Rewritten silclog APIs. Globally interesting changes follows:
1850 silc_log_set_files() changed to silc_log_set_file().
1851 silc_log_set_callbacks() changed to silc_log_set_callback().
1852 ROBOdoc documented silclog header file.
1853 SilcLogCb now returns bool to wether inihibit the default
1854 handler or not (to keep the old behaviour return always TRUE).
1855 The new APIs should also fix the problem of the
1856 silcd_error.log file that was written in the current directory.
1859 Log files streams will remain opened after silc_log_set_file()
1860 call, means less CPU usage notably on high traffic servers.
1861 File streams are now full buffered, and flushed to the disk
1862 every 5 minutes, lesses HD activity and CPU usage.
1863 Messages can be redirected, allowing admins to configure
1864 one single logfile for all server messages.
1865 the silc_log_quick global variable to activate fast-logging.
1866 Affected files lib/silcutil/silclog.[ch]
1868 * Changed some code to conform new silclog APIs. Affected
1869 files are doc/example_silcd.conf.in, silcd/server.c
1870 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1873 * Fixed a memory leak that could occur in some situations.
1874 Affected file silcd/serverconfig.c.
1876 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1878 * Added the silc_client_del_client to remove the client from
1879 all channels as well. Affected file lib/silcclient/idlist.c.
1881 * Fixed the client library to correctly remove the client
1882 from all channels when the client entry is being destroyed.
1883 Affected file lib/silcclient/client_notify.c, command.c.
1885 * Added auto-nicking support to the client library. If the
1886 applicatio now sets client->nickname it will be sent to the
1887 server after connecting by the library. This way for example
1888 SILCNICK (or IRCNICK) environment variables will have effect
1889 and always change the nickname automatically to whatever
1890 it is wanted. Affected file lib/silcclient/client.[ch].
1892 * Renamed silc_server_command_bad_chars to the
1893 silc_server_name_bad_chars and moved it to the
1894 silcd/server_util.[ch]. Added also new function
1895 silc_server_name_modify_bad to return nickname that
1896 includes bad characters as new nickname without those
1897 bad characters. This check and modify is now used in
1898 silc_server_new_client when the username is initially set
1899 as nickname, so it must be checked to be valid nickname.
1900 Affected file silcd/packet_receive.c.
1902 * The nickname length is now taken from the packet for real
1903 and not trusted to strlen() since it clearly can return
1904 wrong length for nickname including bad characters. This
1905 also applies to channel names. Affected file silcd/command.c.
1907 * Removed the lib/silcsilm/modules directory. Modules are now
1908 compiled into the lib/silcsim. Fixed the copying of the
1909 modules to follow symbolic links in Makefile.am.pre.
1911 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1913 * Fixed silc_string_regexify list creation. Fixes bugs with
1914 BAN and INVITE commands in server. The affected file is
1915 lib/silcutil/unix/silcunixutil.c.
1917 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1919 * Removed the command destructor entirely from the server's
1920 command and command reply routines. It is not needed, and
1921 its usage was buggy and caused crashes. Affected files are
1922 silcd/command[_reply].[ch].
1924 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1926 * Cancel protocol and NULL sock->protocol if timeout
1927 occurred during protocol. Affected file silcd/server.c.
1929 * Cancel protocol timeouts always before calling the final
1930 callback, to assure that after final callback is called
1931 no other state will be called for the protocol anymore.
1932 Affected file silcd/protocol.c.
1934 * Print error log if incoming connection configuration could
1935 not be found. Affected file silcd/server.c.
1937 * Fixed JOIN command to correctly save the founder mode
1938 to the client on normal SILC server, when the channel
1939 was created by the router. Affected file silcd/command.c.
1941 * Fixed LIST command (hopefully) to send correct reply
1942 packets. Affected file silcd/command.c.
1944 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1946 * The silc_packet_receive_process now returns FALSE if the
1947 read data was invalid packet, and TRUE if it was ok.
1949 The server now checks that if unauthenticated connection
1950 sends data and its processing fails the server will close
1951 the connection since it could be a malicious flooder.
1953 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1955 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1957 * Make sure the warning about error opening a log file is
1958 printed only once and not everytime it fails (produces
1959 too much useless log). Affected file lib/silcutil/silclog.c.
1961 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1963 * Made the silc_server_daemonise() function more readable.
1964 Affected file silcd/server.c.
1966 * Pid file is now optional, the user may comment it out from
1967 the config file. Removed define SILC_SERVER_PID_FILE, we
1968 don't need a default any longer. Affected file
1969 configure.in.pre, lib/Makefile.am.pre.
1971 * Make some use of the pid file. The server now dies at startup
1972 if it detects a valid pid file on his path. The server would
1973 die anyway in this circumstance, because of the bind() failure.
1974 Affected file silcd/silcd.c.
1976 * No longer compiling lib/dotconf.
1978 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1980 * Fixed JOIN command parsing not to crash. Affected file
1981 lib/silcclient/command.c.
1983 * Fied the NICK_CHANGE notify to add the new client entry
1984 even it is resolved. This removes an <[unknown]> nick
1985 thingy bug in the client. Affected file is
1986 lib/silcclient/client_notify.c.
1988 * Do not try to allocate 0 bytes (efence does not like it)
1989 in lib/silccore/silccomand.c when encoding payload.
1991 * Do not take IRCNICK as nickname in Irssi SILC client since
1992 it is not possible to set nickname before hand connecting
1993 the server (TODO has an entry about adding auto-nicking
1996 * Changed the silc_server_command_pending to check whether
1997 there already exists an pending entry with the specified
1998 command, command identifier and pending callback. This is
1999 to fix IDENTIFY and WHOIS related crashes that may register
2000 multiple pending commands with same identifier. Affected
2001 file silcd/command.c.
2003 * Fixed the server to reconnect to the router even if it
2004 was already reconnecting and EOF was received. This to
2005 fix a possibility that the server wouldn't ever try to
2006 auto-reconnect to the router. Affected file silcd/server.c.
2008 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2010 * Fixed the server's password authentication to use the
2011 length of the locally saved password, and not the one
2012 sent in the packet. Affected file silcd/protocol.c.
2014 * Fixed same password authentication problem in the
2015 Authentication Payload handling routines in
2016 lib/silccore/silcauth.c.
2018 * Yet another password authentication problem fixed with
2019 channel password handling in silcd/command.c.
2021 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2023 * If first character of string in silc_parse_userfqdn is '@'
2024 then do not parse it. Affected file is
2025 lib/silcutil/silcutil.c.
2027 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2029 * Fixed minor bug in IDENTIFY command reply sending, which
2030 caused various weird problems during JOIN when it was
2031 resolving names for users. Affected file silcd/command.c.
2033 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2035 * Fixed the IDENTIFY command reply sending to chech better valid
2036 clients. It was possible to send incomplete list of replies.
2037 Affected file silcd/command.c.
2039 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2041 * Added silc_client_command[s]_[un]register functions now to
2042 dynamically register the commands in client library. Removed
2043 the static table of commands. This allows the client library
2044 to call commands without causing the application to know about
2045 what commands library has called.
2047 Removed the INFO command reply kludge to detect when the command
2048 was called by library. Now library use its own command reply
2049 function for INFO command.
2051 Added function silc_client_command_call to call a command.
2052 Application can use it to call command, not access the structure
2055 Now all commands that are sent by the client library (not
2056 explicitly sent by application) use own command reply functions.
2058 Affected files around lib/silcclient/ and in
2059 irssi/src/silc/core/.
2061 * Fixed the WHOIS command reply sending to chech better valid
2062 clients. It was possible to send incomplete list of replies.
2064 Fixed the WHOIS and IDENTIFY to send the request to router
2065 if normal server did not do it and did not find any results.
2067 Affected file silcd/command.c.
2069 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2071 * Moved the internal data from SilcClient context into its
2072 own file, not accesible to application. Affected files
2073 lib/silcclient/client.h and lib/silcclient/client_internal.h,
2074 and other files in client library.
2076 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2078 * Added doc/examples installation target in Makefile.am.pre.
2081 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2083 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
2084 commands the found client entry will be removed from the
2085 cache, after notifying application about the error. Affected
2086 file lib/silcclient/command_reply.c.
2088 * Changed the /MSG to check for exact nickname user gave, and
2089 not let `nick' match `nick@host' if it is only one found. Now,
2090 user must type the exact nickname (like nick@host2) even if
2091 there are no more than one same nicks found. This is to avoid
2092 a possibility of sending nickname to wrong nickname since
2093 `nick' could match `nick@host'. Affected file is
2094 irssi/src/core/silc-servers.c.
2096 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2098 * Do not print "you are now server operator" or similar when
2099 giving /away command. Affected files are
2100 irssi/src/silc/core/client_ops.c, silc-servers.h.
2102 * Made the silc_server_command_pending_error_check to send
2103 the same command reply payload it received back to the
2104 original sender of the command. This way all arguments
2105 that was received by the server will be received by the
2106 client too. Affected file silcd/command.c.
2108 * Added the silc_idcache_add to return the created cache entry
2109 to a pointer. Affected file lib/silccore/silcidcache.[ch].
2111 * Add global clients to expire if they are not on any channel.
2112 This is because normal server will never know if they signoff
2113 if they are not on any channel. The cache expiry will take
2114 case of these entries. This is done by normal servers only.
2115 The affected files are silcd/command_reply.c,
2116 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
2118 * If server receives invalid ID notification for WHOIS or
2119 IDENTIFY and the ID exists in the lists, it is removed.
2120 Affected file silcd/command_reply.c.
2122 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
2123 in client then client entry that it matches is searched and
2124 the nickname is printed on the screen for user. Affected
2125 file irssi/src/silc/core/client_ops.c.
2127 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2129 * Use cache entry expire time in the LIST command reply to
2130 purge old entries from the cache after the LIST command
2131 reply has been received. This way we don't have non-existent
2132 entries in the cache for too long. Affected file is
2133 silcd/command_reply.c.
2135 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2137 * If we are normal server, and we've not resolved client info
2138 in WHOIS or IDENTIFY from router, and it is global client,
2139 we'll check whether it is on some channel. If it is not
2140 then we cannot be sure about its validity and will resolve it
2141 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
2142 file silcd/command.c.
2144 * Search channel by name (if possible) rather than by ID
2145 in IDENTIFY command's command reply. Affected file is
2146 silcd/command_reply.c.
2148 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2150 * Distribute to the channel passphrase in CMODE_CHANGE notify.
2151 Updated specs and implemented it. Affected file silcd/command.c,
2152 silcd/packet_send.c and silcd/packet_receive.c.
2154 * Implemented the <founder auth> payload handling in the JOIN
2155 command. If provided all conditions for channel joining
2156 except requirement to provide correct passphrase can be
2157 overrided by the channel founder. Updated the protocol specs.
2158 Affected file silcd/command.c.
2160 Added support for founder auth in JOIN command in client
2161 library. Fixed the parsing of the JOIN command now to support
2162 all options as they should be. The affected file is
2163 lib/silcclient/command.c.
2165 * Optimized the WHOIS and IDENTIFY commands to send the request
2166 to router only if it includes nicknames or other names. If
2167 they include only IDs then check the local cache first before
2168 routing. Affected file is silcd/command.c.
2170 * Added channels topic announcements. Affected file is
2171 silcd/packet_receive.c and silcd/server.c.
2173 * Fixed the silc_server_send_notify_topic_set to really destine
2174 the packet to channel. Affected file silcd/packet_send.c.
2176 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
2177 library. Affected file lib/silcclient/client_notify.c.
2179 * Added UMODE announcements. Affected file silcd/server.c.
2181 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2183 * Memory leak fixes in:
2185 lib/silcutil/silcsockconn.c
2186 lib/silcske/silcske.c
2187 lib/silcske/groups.c
2189 lib/silccrypt/silcpkcs.c
2190 lib/silccore/silccommand.c
2191 lib/silccore/silcidcache.c
2196 * ROBOdoc documented the lib/silcske/groups.h file and a
2197 bit changed the interface for better.
2199 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2201 * Update the client entry context in the ID cache after
2202 nick change. Affected file lib/silcclient/command.c.
2203 Fixes the CUMODE command when regaining founder privileges,
2204 and a little WHOIS problem.
2206 * Fixed silc_net_gethostbyname to correctly call the
2207 inet_ntop. Affected file lib/silcutil/silcnet.c.
2209 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2211 * Added IPv6 support checking to the configure.in.pre, added
2212 also --enable-ipv6 option to override the check. Affected
2213 file configure.in.pre.
2215 * The silc_thread_create now calls the start function
2216 directly if threads support is not compiled in. Removes
2217 ugly #ifdef's from generic code. Affected files are
2218 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
2220 * Added silc_net_gethostby[name/addr]_async to asynchronously
2221 resolve. Affected files are lib/silcutil/silcnet.[ch].
2223 * Added support for rendering IPv6 based server, client and
2224 channel IDs. Affected file lib/silcutil/silcutil.c.
2226 * Added support for creating IPv6 based server IDs. Affected
2227 file is silcd/serverid.c.
2229 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2231 * Added silc_net_gethostby[addr/name] into the
2232 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
2233 routines. Added silc_net_is_ip[4/6]. Affected file is
2234 lib/silcutil/unix/silcunixnet.c. All routines that take
2235 address as argument now supports both IPv4 and IPv6 addresses.
2237 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2239 * Fixed LIST command reply sending in server. Affected file
2242 * Server now sends the kicker's client ID in the KICK notify
2243 to the kicked client. Affected file silcd/command.c.
2245 * The client library now parses the kickers client ID and
2246 UI displays it. Affected files lib/silcclient/client_notify.c
2247 and irssi/src/silc/core/silc-channels.c, module-formats.c.
2249 * Made all payload parsing function prototypes consistent.
2250 They all take now const unsigned char * and uint32 pair as
2251 the payload data instead of SilcBuffer. Changes all around
2252 the source tree. Other unsigned char* -> const unsigned char*
2253 changes around the tree as well.
2255 * Optimized SFTP client and server packet sending not to
2256 allocate new buffer for each packet but to recycle the
2257 first allocated buffer. Affected files are
2258 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
2260 * Optimized the SFTP client to use SilcList instead of
2261 SilcDList for requests, because it is faster. Affected file
2262 is lib/silcsftp/sftp_client.c.
2264 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
2265 into lib/silccore/silcid.[ch].
2267 Renamed silcpayload.[ch] into silcargument.[ch].
2269 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2271 * If client entry is deleted with active key agreement
2272 session, abort the session.
2274 The silc_client_abort_key_agreement now calls the completion
2275 callback with new SILC_KEY_AGREEMENT_ABORTED status.
2277 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
2280 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2282 * Don't use __restrict in older GCC's. Affected file is
2283 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
2285 * silc_net_localhost now attempts to reverse lookup the
2286 IP/hostname. Affected file lib/silcutil/silcnet.c.
2288 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
2289 command. It can be used to gain founder privileges at
2290 the same time when joining the channel.
2292 Defined that the SILC_NOTIFY_TYPE_KICKED send the
2293 kicker's client ID as well. Updated protocol specs.
2295 Defined that the server must send SILC_COMMAND_IDENTIFY
2296 command reply with error status to client who sent
2297 private message with invalid client ID.
2299 Updated the protocol specification.
2301 * Added silc_server_send_command_reply to send any
2302 command reply. Affected file silcd/packet_send.[ch].
2304 * Added silc_id_payload_encode_data to encode ID payload
2305 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
2307 * The server now send IDENTIFY command reply with error
2308 status if client ID in private message is invalid. Affected
2309 file silcd/packet_receive.c.
2311 * Save the server key file with server's IP address in
2312 the filename instead of hostname. The affected file is
2313 irssi/src/silc/core/client_ops.c.
2315 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2317 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
2320 * Added libtool support for compiling shared objects in
2321 lib/silcsim. Affected file configure.in.pre and
2322 lib/silcsim/Makefile.am. Original patch by cras.
2324 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2326 * Pid file configuration, and server's config file fixes
2327 patch by toma. Updated CREDITS file.
2329 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2331 * Fixed silc_client_channel_message to not try to decrypt
2332 the message twice if it resolved the destination client
2333 information. This could cause of dropping one channel
2334 message. Affected file lib/silcclient/client_channel.c.
2336 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2338 * Added silc_client_run_one into lib/silcclient/silcapi.h and
2339 lib/silcclient/client.c. This function is used when the SILC
2340 Client is run under some other scheduler, or event loop or
2341 main loop. On GUI applications, for example this may be
2342 desired to used to run the client under the GUI application's
2343 main loop. Typically the GUI application would register an
2344 idle task that calls this function multiple times in a second
2345 to quickly process the SILC specific data.
2347 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2349 * Fixed silc_server_drop() for dropping the supplementary
2350 groups as well, this could cause a security hole on some
2353 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2355 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
2358 * Write PID file after dropping privileges. Added -F option
2359 to run server on foreground. A patch by debolaz.
2360 Affected files silcd/server.c, silcd/silcd.c.
2362 * Fixed MOTD to return the MOTD file server name. Affected
2363 file silcd/command.c.
2365 * Added INFO command reply handling to the Irssi SILC Client.
2366 Affected file irssi/src/silc/core/client_ops.c.
2368 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2370 * Fixed the silc_idcache_list_* routines to really support
2371 the dynamic list. Fixes a crash. Affected file is
2372 lib/silccore/silcidcache.c.
2374 * Fixed the LIST command reply to really call LIST command's
2375 pending callbacks. Affected file silcd/command_reply.c.
2377 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2379 * Update conn->local_entry->nickname after giving NICK
2380 command. Affected file lib/silcclient/command.c.
2382 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
2384 * Added the [pid] option to the silcd configuration file
2386 Affected files: serverconfig.[ch] and silcd.c
2388 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2390 * Save fingerprint in WHOIS command reply in server.
2391 Affected file silcd/command_reply.c.
2393 * Fixed NICK commands pending callback registration.
2394 Affected file lib/silcclient/command.c.
2396 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2398 * Use ++server->cmd_ident when sending commands in server,
2399 instead of random number. Affected file silcd/command.c.
2401 * Fixed GETKEY command reply to call actually GETKEY pending
2402 command callbacks. Affected file silcd/command_reply.c.
2404 * A bit stricter check for nicknames. Check for same nickname
2405 in NICK command also. Affected file silcd/command.c.
2407 * Do not call INFO command everytime client ID changes, only
2408 during first connecting. Affected file lib/silcclient/client.c.
2410 * Set the new nickname only after successful command reply for
2411 NICK command is returned by server. Affected file
2412 lib/silcclient/command.c.
2414 * Remove nicknames from nicklist during server_signoff notify.
2415 Should fix /NAMES bit more. The affected file is
2416 irssi/src/silc/core/silc-channels.c.
2418 * Added `fingerprint' field to the SilcIDListData in the
2419 silcd/idlist.h to hold the fingerprint of the client's
2422 Send the fingerprint of the client's public key in WHOIS
2425 Affected files silcd/command.c, and silcd/idlist.[ch].
2427 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
2428 create fingerprint from given data.
2430 * Show the fingerprint of the client's public key in WHOIS.
2431 Affected files irssi/src/module-formats.[ch] and
2432 irssi/src/silc/core/client_ops.c.
2434 * Format the multiple same nicknames also during JOIN and
2435 NICK_CHANGE notifys. Affected file is
2436 lib/silcclient/client_notify.c.
2438 * Do not print error on screen for invalid private message
2439 payload since it can come if someone is sending private
2440 messages with wrong key. Affected file
2441 lib/silccore/silcprivate.c.
2443 * Fixed multiple concurrent /PING crash. Affected file
2444 lib/silcclient/command.c.
2446 * Changed the wrong ID encoding. All IP addresses must be
2447 in MSB first order in encoded format. They were encoded
2448 wrong and was in LSB format. Affected files are
2449 silcd/serverid.c, lib/silcutil/silcutil.c.
2451 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
2453 * Call the `connect' client operation through the scheduler
2454 in case of error. Affected file lib/silcclient/client.c.
2456 * Call the `failure' client operation even if the error
2457 occurred locally during a protocol. Affected file is
2458 lib/silcclient/protocol.c.
2460 * Added support of sending LIST command to router from normal
2461 server. This way normal server can get list of all channels
2462 in the network too. Fixed the channel list sending in the
2463 server too. Affected files are silcd/command.c, and
2464 silcd/command_reply.[ch].
2466 * Added silc_server_update_channels_by_server and
2467 silc_server_remove_channels_by_server. They are used during
2468 disconnection of primary router and in backup router protocol.
2469 Affected file silcd/server_util.[ch], silcd/server.c and
2470 silcd/server_backup.c.
2472 * Fixed channel adding to global list in IDENTIFY command
2473 reply in server. Affected file silcd/command_reply.c.
2475 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2477 * If the incoming packet type is REKEY or REKEY_DONE process
2478 that packet always synchronously. Fixes yet another MAC
2479 failed error on slow (dialup) connections. Affected file
2480 lib/silcclient/client.c and silcd/server.c.
2482 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2484 * Call check_version SKE callback for initiator too. Affected
2485 file lib/silcske/silcske.c.
2487 * Implemented fix for security hole found in the SKE that was
2488 fixed in the specification few days back; the initiator's
2489 public key is now added to the HASH value computation.
2490 Added backwards support for the old way of doing it too, for
2491 old clients and old servers. Affected file is
2492 lib/silcske/silcske.c.
2494 * Enabled mutual authentication by default in SKE. If initiator
2495 is not providing mutual authentication the responder will
2496 force it. This will provide the proof of posession of the
2497 private key for responder. The affected files are
2498 lib/silcclient/protocol.c and silcd/protocol.c.
2500 * Do not cache anymore the server's public key during SKE.
2501 We do mutual authentication so the proof of posession of
2502 private key is done, and if the server is authenticated in
2503 conn auth protocol with public key we must have the public
2504 key already. Affected file silcd/protocol.c.
2506 * Added new global debug variable: silc_debug_hexdump. If
2507 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
2508 file lib/silcutil/silclog.[ch].
2510 * Fixed compilation warning due to char * -> const char *.
2511 Affected files lib/silcutil/silcnet.h, and
2512 lib/silccore/silcauth.[ch].
2514 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2516 * Fixed CMODE command when new channel key was created. If
2517 the creation failed the old key was removed. Next time giving
2518 same command would crash the server since the old key was
2519 freed already. Affected file silcd/command.c.
2521 * Fixed the silc_server_announce_get_channels to not crash
2522 on reconnect. Affected file silcd/server.c.
2524 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2526 * Added silc_log_set_debug_string function to set a regex
2527 string to match for debug output. Only the function names,
2528 or filenames matching the given debug string is actually
2529 printed. This way it is possible to filter out those debug
2530 strings that user is not interested in.
2532 Fixed a bug in silc_string_regexify.
2534 Affected files lib/silcutil/silclog.[ch], and
2535 lib/silcutil/unix/silcunixutil.c.
2537 * Changed the -d options in both server and Irssi SILC client
2538 to take the debug string as argument. Affected files
2539 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
2541 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2543 * Added silc_hash_babbleprint to create a Bubble Babble
2544 Encoded fingerprint. The encoding is developed by Antti
2545 Huima (draft-huima-babble-01.txt), and it creates human
2546 readable strings out of binary data. Affected file
2547 lib/silccrypt/silchash.[ch].
2549 * Print the babble print now in addition of fingerprint as well
2550 in Irssi SILC client. Affected files are
2551 irssi/src/fe-common/silc/module-formats.[ch],
2552 irssi/src/fe-common/silc/core/client_ops.c.
2554 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2556 * Fixed a security problem found in SKE. The initiator's
2557 public key too is now added to the HASH hash value creation
2558 which is signed by the responder to create the SIGN value.
2559 This will prevent anyone in the middle to lie to the responder
2560 about the initiator's public key. If this is done now, the
2561 man in the middle will get caught. Updated the protocol
2564 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2566 * Better installation directory handling. Configure module
2567 paths and other paths automatically to example_silc* files
2568 in doc/. A patch by toma.
2570 * Fixed compiler warning from MPI library, and from SILC RNG.
2573 * Added SILC_SERVER_PID_FILE to define the pid file for server.
2574 It can be configured with ./configure. A patch by toma.
2576 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2578 * Find correct make to use in prepare-clean. A patch by
2579 toma. Affected file prepare-clean.
2581 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
2583 * Added irssi variables use_auto_addr, auto_bind_ip,
2584 auto_bind_port and auto_public_ip.
2586 * Changed the interface for silc_client_send_key_agreement
2587 in lib/silcclient/silcapi.h
2591 irssi/src/silc/core/silc-core.c
2593 lib/silcclient/silcapi.h
2594 irssi/src/silc/core/silc-channels.c
2595 lib/silcclient/client_keyagr.c
2598 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2600 * Added silc_pkcs_public_key_compare to compare two
2601 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
2603 * Check that the client who set the founder mode on the
2604 channel is the same client that is giving the founder
2605 mode to itself. It is done by comparing the saved public
2606 key (it is saved even in the authentication is passphrase).
2607 Affected file silcd/command.c.
2609 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2611 * Do not process packet for disconnected socket connection.
2612 Affected file lib/silccore/silcpacket.c.
2614 * Process the DISCONNECT packet through scheduler in the
2615 client library. Affected file lib/silcclient/client.c.
2617 * Fixed the silc_client_packet_parse to not to increase
2618 the packet sequence number if the conn->sock and the
2619 current socket connection is not same. This can happen
2620 for example during key agreement when the conn includes
2621 multiple socket connections (listeners). Affected file
2622 lib/silcclient/client.c.
2624 * The sender of the file transfer request now provides also
2625 the pointer (listener) for the key exchange protocol. If
2626 the listener cannot be created then it sends empty key
2627 agreement and lets the receiver provide the listener.
2629 Added `local_ip' and `local_port' arguments to the
2630 silc_client_file_send. If they are provided they are used,
2631 if not then it will attempt to find local IP address, if
2632 not found or bind fails then the remote client will provide
2635 Affected files are lib/silcclient/client_ftp.c and
2636 lib/silcclient/silcapi.h.
2638 * Extended the FILE SEND command to support defining the
2639 local IP and port for key exchange listener. They are

2644 * Defined to WHOIS command reply the sending of fingerprint
2645 of the client's public key (if the proof of posession of the
2646 corresponding private key is verified by the server).
2647 Updated to the protocol specification.
2649 * Added support of receiving the client's public key's
2650 fingerprint in command reply in client library. Affected
2651 file is lib/silcclient/command_reply.c, and
2652 lib/silcclient/idlist.[ch].
2654 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>

2711 preserve the WHOWAS info for the client. Affected file
2712 silcd/server_util.c.
2714 * Fixed SERVER_SIGNOFF notify handling in the server. The
2715 server is now able to process incoming SERVER_SIGNOFF notify
2716 for a server that it doesn't even know about. It will remove
2717 the clients provided in the notify. Affected file
2718 silcd/packet_receive.c.
2720 * Check for partial packet in data queue after every packet that
2721 was found from the queue. Return and wait for more data if
2722 there is partial data in queue. Affected file is
2723 lib/silccore/silcpacket.c.
2725 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>

2740 irssi/src/fe-common/silc/module-formats.[ch].
2742 * Wrote a help file for FILE command.
2744 * Added silc_rng_global_get_byte_fast to get not-so-secure
2745 random data as fast as possible. Random data is read from
2746 /dev/urandom if available and from the SILC RNG if not
2747 available. It is used in padding generation. Affected file
2748 lib/silccrypt/silcrng.[ch].
2750 * All packets in client library are now processed synchronously.
2751 Optimized packet processing a lot. Affected file
2752 lib/silcclient/client.c.
2754 * All server connection packets are processing synchronously
2755 now in server, to optimize packet processing. Affected file
2758 * Include files are installed now only in Toolkit distribution
2759 if make install is given. Affected files: all Makefile.am's.
2761 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2763 * Assure that silc_client_notify_by_server_resolve does not
2764 resolve the client information multiple times. If it cannot
2765 be found by the first it cannot be found at all. Affected
2766 file lib/silcclient/client_notify.c.
2768 * Fixed WHOWAS command reply calling. Affected file
2769 lib/silcclient/command_reply.c.
2771 * Removed all references to silc_idlist_get_client from the
2772 Irssi SILC client since that call is internal call used by
2773 the library. The Irssi SILC client will use now client
2774 retrieval functions found in silcapi.h.
2776 * Fixed a bug in resolving nickname info before sending
2777 private message. It used freed memory. Affected file
2778 irssi/src/silc/core/silc-servers.c.
2780 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2782 * Assure my_channels statistics cannot go negative in server.
2783 Affected files silcd/server.c, silcd/server_util.c.

2799 * Added silc_net_localip to return local host's IP address.
2800 Affected file lib/silcutil/silcnet.[ch].
2802 * If key exchange or rekey protocol is active for a connection
2803 parse all packets syncronously since there might be packets
2804 in packet queue that we are not able to process without first
2805 processing packets before them. Affected file silcd/server,
2806 lib/silcclient/client.c.
2808 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2809 whether library should continue processing the packet.
2810 Affected file lib/silccore/silcpacket.h.
2812 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and

2856 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
2857 is incomplete and is being resolved, it won't be resolved
2860 Make sure also that USERS command reply does not resolve
2861 twice information. Affected file is
2862 lib/silcclient/command_reply.c.
2864 Make sure that silc_client_get_clients_by_list does not
2865 resolve twice same information.
2867 * Check for valid client->id in the silc_server_free_client_data.
2868 Affected file silcd/server.c.
2870 * Fixed /GETKEY nick@server not to crash if the server entry
2871 is not found. Affected file lib/silcclient/command.c.
2873 * Fixed the silc_server_check_cmode_rights to check the
2874 requested modes correctly. Affected file silcd/command.c.
2876 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2878 * Better checks for non-printable chars in nick added.
2879 Affected file silcd/command.c.
2881 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2883 * Call the silc_server_udpate_servers_by_server in the
2884 primary router that comes back online in the backup resuming
2885 protocol. Otherwise it routes packets wrong. Affected file
2886 silcd/server_util.[ch], silcd/server_backup.c.
2888 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2890 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2891 lib/silcutil/silcbuffmt.[ch].
2893 * Redefined the SILC packet header to include the padding
2894 length. Affected file lib/silccore/silcpacket.[ch].
2896 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2897 length for maximum padding up to 128 bytes). Affected
2898 file lib/silccore/silcpacket.h.
2900 * Removed all backwards support for old 0.5.x MAC thingies.
2901 The SILC packet header change makes it impossible to be
2902 backwards compatible.
2904 * Send the ENDING packet with timeout in the backup resuming
2905 protocol. This is to assure that all routers has connected
2906 to the primary router. Affected file silcd/server_backup.c.
2908 * Changed the RNG to take the first IV from random data. It
2909 used to take it from zero actually. Changed the RNG also
2910 to use /dev/urandom during session. /dev/random is used
2911 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2913 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2915 * Changed the SILC packet header to have the first two bytes
2916 (the packet length) encrypted. Affected files aroung the
2917 code tree, lib/silccore/silcpacket.[ch]. Removed the
2918 SilcPacketCheckDecrypt callback. It is not needed anymore
2919 since the silc_packet_receive_process will determine now
2920 whether the packet is normal or special.
2922 * Implemented the unidirectional MAC keys. Affected files
2923 lib/silcske/silcske.c, silcd/protocol.c and
2924 lib/silcclient/protocol.c.
2926 * Implemented the packet sequence number to the MAC computation.
2927 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
2928 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
2929 lib/silcclient/protocol.c.
2931 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2933 * Allow backup router to announce servers. All servers
2934 announced by backup router are added to the global list
2935 automatically. Update hte server's socket to our primary
2936 router also when backup router announces a server.
2937 Affected file silcd/packet_receive.c.
2939 * Do not update the client->router in the function
2940 silc_server_udpate_clients_by_server if the client is on
2941 global list. We might fail to find any specific server
2942 for locally connected clients and local cell clients. They
2943 should still use the `from' and not `to' as client->router.
2944 This fixes backup router resuming protocol. Affected file
2945 silcd/server_util.c.
2947 * Decrease channel statistics count only if the channel
2948 deletion worked. Affected files are silcd/server.c and
2949 silcd/server_util.c.
2951 * Added silc_server_update_servers_by_server to update origin
2952 of all server entries. Used during backup router protocol.
2953 Affected files silcd/server_util.[ch], silcd/server.c. and
2954 silcd/backup_router.c.
2956 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
2957 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
2958 silc_hmac_get_hash and silc_hmac_get_name. Affected file
2959 lib/silccrypt/silchmac.c.
2961 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2963 * Assure that router cannot reroute the same channel message
2964 to the sender. Affected file silcd/packet_receive.c.
2966 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2968 * Made better checks that the channel message is not sent
2969 to the router it came from. Affected file is
2970 silcd/packet_send.c. Fixed memory leak too.
2972 * Announce informations for incoming router connection, but
2973 only after checking if it is replaced by backup router.
2974 Affected file silcd/packet_receive.c.
2976 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2978 * Fixed the backup resuming protocol to work in multiple
2979 router environment. Affected file silcd/server_backup.c.
2981 * Route packet only to one router in the function
2982 silc_server_packet_send_to_channel. Affected file is
2983 silcd/packet_send.c.
2985 * Fixed silc_server_send_notify_dest to set the broadcast
2986 flag. Fixed the silc_server_send_notify_topic to actually
2987 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2988 Affected file silcd/packet_send.c.
2990 * Changed the SFTP Filesystem interface. Changed the
2991 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2992 the filesystem operation function. The SilcSFTPFilesystem
2993 is now a context that is allocated by all filesystem allocation
2994 functions and it already includes the operations structure
2995 and filesystem specific context. It is given as argument
2996 now to the silc_sftp_server_start. This made the interface
2997 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2998 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
3000 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3002 * Changed the backup router adding and getting interfaces
3003 in the server. The router that will be replaced by the
3004 specified backup router is now sent as argument. Affected
3005 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
3008 * Added silc_net_addr2bin_ne to return the binary form of
3009 the IP address in network byte order. Affected files
3010 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
3012 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3014 * Check for existing server ID in silc_server_new_server
3015 and in silc_server_connect_to_router_final and remove the
3016 old entry if it exists. Affected file silcd/packet_receive.c,
3019 * Send the channel message always to only one router, either
3020 in upstream or downstream. Affected file is
3021 silcd/packet_send.c.
3023 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3025 * Wrote the definition of the backup resuming protocol to the
3026 protocol specification.
3028 * Removed one redundant channel key generation from normal
3029 server during joining procedure. Removed one redundant
3030 channel key sending from server to router during joining
3031 procedure. Affected file silcd/command.c.
3033 * Made minor bugfixes to the backup router resuming protocol.
3034 Affected file silcd/server_backup.c, server.c.
3036 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3038 * Added --disable-asm configuration option. Affected files
3039 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
3042 * Implemented the backup resuming protocol that is used to
3043 resume the primary router position in the cell after the
3044 primary router comes back online. Affected files
3045 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
3046 and silcd/server_util.[ch].
3048 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3050 * Sleep two (2) seconds after sending QUIT command to server.
3051 Affected file lib/silcclient/command.c.
3053 * Assure that if outgoing data buffer is pending do not force
3054 send any data. Affected file silcd/packet_send.c.
3056 * Assure that if outgoing data buffer is pending do not force
3057 send any data. Affected file lib/silcclient/client.c.
3059 * Implemented the backup router support when the primary router
3060 goes down. The servers and routers can now use the backup
3061 router as new primary router without loosing connectivity.
3063 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3065 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
3066 in the server to indicate disabled entry. All data read
3067 from the connection will be ignored and no data is sent
3068 for entry that is disabled. Affected files are
3069 silcd/idlist.h, silcd/server.c.
3071 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3073 * Created SFTP client and server test programs in the
3074 lib/silcsftp/tests directory.
3076 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3078 * Implemented memory filesystem (virtual filesystem) for
3079 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
3082 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3084 * Implemented the SFTP (SSH File Transfer Protocol) to the
3085 lib/silcsftp. It includes SFTP client and SFTP server
3088 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3090 * Moved lib/silccore/silcprotocol.[ch] to the
3091 lib/silcutil library.
3093 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
3094 take variable argument list pointer as argument. Affected
3095 file lib/silcutil/silcbuffmt.[ch].
3097 * Added silc_buffer_set function that is used to set data
3098 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
3099 Affected file lib/silcutil/silcbuffer.h.
3101 * Changed various routines in the core library to use the new
3102 silc_buffer_set instead of allocating new buffer only for
3105 * Added 64-bit value formatting and unformatting support to the
3106 silc_buffer_[un]format routines. Affected file is
3107 lib/silcutil/silcbuffmt.[ch].
3109 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
3110 to includes/bitmove.h.
3112 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3114 * Fixed channel user mode saving in client library. Affected
3115 file lib/silcclient/command[_reply].c.
3117 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3119 * Defined the file transfer to the SILC Protocol. Added
3120 new packet type SILC_PACKET_FTP and defined File Transfer
3121 Payload. The mandatory file transfer protocol is SFTP
3122 (SSH File Transfer Protocol). Affected file in addition
3123 of the internet draft is lib/silccore/silcpacket.h.
3125 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
3126 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
3127 is used as part of backup router protocol when the primary
3128 router of the cell is back online and wishes to resume
3129 the position as primary router.
3131 * Redefined the MAC generation keys in the protocol. The
3132 same key is not used anymore in both direction. Both
3133 direction will now use different keys for sending and
3134 receiving. This fixes a potential security flaw. This
3135 change causes incompatibilities in the protocol.
3137 * Redefined also the MAC computation from the packet.
3138 An packet sequence number is now added to the MAC
3139 computation. This prevents possible replay attacks against
3140 the protocol. This change too causes incompatibilities
3143 Added `sequence' field to the SilcPacketContext to hold
3144 the current sequence number for the packet.
3146 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3148 * Added `created' field to the SilcIDListData in the file
3149 silcd/idlist.h to indicate the time when the entry was
3152 * Added `created' field to the SilcChannelEntry too. Affected
3153 file silcd/idlist.h.
3155 * Added `creation_time' aguments to all the announcement functions
3156 in the server. If it is provided then only the entries that
3157 was created after the provided time frame are actually
3158 announced. Affected file silcd/server.[ch].
3160 * The protocol says that the Channel ID's IP address must be
3161 based on the router's IP address. Added check for this in
3162 the silc_server_new_channel when processing incoming New Channel
3163 Payload. Affected file silcd/packet_receive.c.
3165 * Print out the correct version with --version in SILC client.
3166 Affected file irssi/src/silc/core/silc-core.c.
3168 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3170 * Fixed WHOWAS command to check for completnes of the client
3171 entry always, not just when the command is coming from client.
3172 Affected file silcd/command.c.
3174 * Added new function silc_server_packet_queue_purge to purge the
3175 outgoing data queue to the network. After the function returns
3176 it is guaranteed that the outgoing packet queue is empty.
3177 Affected file silcd/packet_send.[ch].
3179 * Purge the outgoing packet queue in the rekey protocol's final
3180 callback to assure that all rekey packets go to the network
3181 before quitting the protocol. Affected file silcd/server.c.
3183 * Added silc_client_packet_queue_parse as similar function as
3184 in server to the client library. The affected file is
3185 lib/silcclient/client.c.
3187 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3189 * Splitted silcd/server.c and created silcd/server_util.[ch]
3190 for utility functions.
3192 * Added new socket flag SILC_SF_DISABLED to indicate that the
3193 connection is open but nothing can be sent to or received from
3194 the connection. Affected file lib/silcutil/silsockconn.[ch].
3195 The checking for disabled socket is checked in the low level
3196 silc_socket_write and silc_socket_read functions.
3198 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3200 * Allow only nicknames and channel names that fits into the
3201 7-bit unsigned char ASCII set. Affected file silcd/command.c.
3203 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3205 * When processing JOIN command reply in server check that if
3206 the channel exists in our global list we'll move it the local
3207 list. Affected file silcd/command_reply.c.
3209 * Fixed the check whether client is joined on the channel already
3210 in JOIN command. Affected file lib/silcclient/command.c.
3212 * Fixed the JOIN command reply to check whether the channel
3213 already exists. Affected file lib/silcclient/command_reply.c.
3215 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3217 * Added silc_ske_status_string to map the SKE error numbers
3218 to readable strings. The affected files are
3219 lib/silcske/silcske[_status].[ch].
3221 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3223 * Do not show the private channels on the WHOIS channel list
3224 as it is not allowed by the protocol. The affected file is
3227 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3229 * Assure that the packet length digged from the actual packet
3230 is something sensible in the silc_packet_decrypt_rest_special
3231 in lib/silccrypt/silcpacket.c.
3233 * Free and NULL the allocated pointer in silc_hmac_alloc if
3234 the HMAC allocation fails. The affected file is
3235 lib/silccrypt/silchmac.c.
3237 * Print the selected security properties to the log files in
3238 the server. Affected file silcd/protocol.c.
3240 * Add SKE's reference counter even if calling the completion
3241 callback manually. Otherwise it goes negative, although it
3242 does not cause any problems. The affected file is
3243 lib/silcske/silcske.c.
3245 * Remove the client entry with short timeout after giving the
3246 KILL command. Affected file lib/silcclient/command.c.
3248 * Fixed to send error reply in WHOIS and IDENTIFY commands in
3249 case all found clients are already disconnected (WHOWAS would
3250 found them) in the server. Affected file silcd/command.c.
3252 * Update the last_receive (time of last data received) to be
3253 updated only when received private or channel message so that
3254 the idle time showed in WHOIS makes more sense.
3256 * Added boolean field `valid' in to the SilcClientEntry in the
3257 client library to indicate whether the entry is valid or not.
3258 This fixes the nickname change bug on channel when changing
3259 the nickname to be same than the old (like nick to Nick) the
3260 nickname formatter doesn't set the new nick anymore to Nick@host.
3261 Affected file lib/silcclient/idlist.[ch].
3263 * Now actually fixed the nickname changing on disconnection.
3264 Added new function silc_change_nick to the Irssi SILC Client.
3265 Affected file irssi/src/silc/core/client_ops.c,
3266 irssi/src/silc/core/silc-nicklist.[ch].
3268 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3270 * Check that the public key exists in the GETKEY command before
3271 trying to encode it. Affected file silcd/command.c.
3273 * Print some notifications on received public keys with GETKEY
3274 command in the Irssi SILC Client. Affected files are
3275 irssi/src/fe-common/silc/module-formats.[ch],
3276 irssi/src/silc/core/client_ops.c.
3278 * Use IDENTIFY command to resolve the server information in the
3279 GETKEY command instead of INFO command. Affected file
3280 lib/silcclient/command.c.
3282 * All command reply functions in the client library now calls
3283 the pending command reply callbacks even if an error has
3284 occurred. The server has done this a long time and now it was
3285 time to move the client library to this as well. Now all
3286 errors can be delivered back to the pending command reply
3287 callbacks if necessary. Affected files are
3288 lib/silcclient/command[_reply].[ch].
3290 * Change the nickname on disconnection back to the username
3291 because in reconnect the server will enforce it to it anyway.
3292 Affected file irssi/src/silc/core/silc-servers.c.
3294 * Fixed a config file parsing bug in the Irssi SILC client.
3295 Affected file irssi/src/silc/core/clientconfig.c.
3297 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3299 * When printing the channel mode on JOIN, verify that the
3300 channel key and channel's HMAC are valid. Affected file
3301 irssi/src/silc/core/client_ops.c.
3303 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3305 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
3306 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
3307 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
3309 * Removed channel key rekey task deleting from the function
3310 silc_server_save_channel_key. Affected file silcd/server.c.
3311 Added explicit timeout task context instead that is used to
3312 delete the task if we are registering a new task before the
3313 new task has elapsed.
3315 * When channel key rekey occurs the client library now saves
3316 the old channel key for a short period of time (10 seconds) and
3317 is able to use it in case some is still sending channel
3318 messages encrypted with the old key after the rekey. Affected
3319 file lib/silcclient/[idlist.h|client_channel.c].
3321 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3323 * Added check to the silc_server_new_id_real to not accept
3324 new ID if it is the sender's own ID. Affected file is
3325 silcd/packet_receive.c.
3327 * Assure that we do not announce ourself or the one we've
3328 sending our announcements when we're router and are announcing
3329 servers to our primary router. Affected file silcd/server.c.
3331 * Fixed silc_server_command_identify_check_client to assemble
3332 correct WHOIS packet. It send corrupted WHOIS packet and
3333 caused problem with router to router connections. Affected
3334 file silcd/command.c.
3336 Fixed also silc_server_command_whois_check the same way
3337 as for the IDENTIFY command.
3339 * Added new SilcIDListStatus to the server in the SilcIDListData
3340 structure. The status now includes the current status of
3341 the entry (like registered, resolved etc.). Affected file
3342 silcd/idlist.[ch]. Defined a bunch of different status types
3343 as well. This replaced the old boolean registered field as well.
3345 Added resolve_cmd_ident field to the SilcClientEntry structure
3346 too so that if the entry is for example being resolved so
3347 another command may attach to the same pending command reply
3348 without requiring to resolve the same entry again. This concept
3349 should optimize the WHOIS and the IDENTIFY resolving under
3350 heavy load by taking away unnecessary resolving for entries
3351 that are being resolved already.
3353 Added support for adding multiple pending commands for one
3354 command idenfier. Affected file silcd/command[_reply].[ch].
3356 * Fixed WHOIS and IDENTIFY save to remove the cache entry
3357 before deleting the data. Otherwise the hash table will have
3358 freed data in comparison functions. Affected file is
3359 silcd/command_reply.c.
3361 * Fixed silc_idlist_replace_client_id to add the new entry to
3362 the cache with NULL nickname. Otherwise there will be invalid
3363 memory as the nickname after the nickname is freed. Affected
3364 file silcd/packet_receive.c.
3366 * Fixed the silc_idlist_get_clients_by_hash. The entries was
3367 saved into wrong slots because the previous number of entries
3368 was not taken into account. Affected file silcd/idlist.c.
3369 Fixed same thing in silc_idlist_get_clients_by_nickname too.
3371 * If we are router and we receive JOIN notify to a channel that
3372 does not have any users then notified client is marked as the
3373 channel founder, as it is it. The affected file is
3374 silcd/packet_receive.c
3376 * Added to the extended hash table API's table_del_*ext functions
3377 the destructor as argument too, so that the caller can decide
3378 which destructor to use or whether to use destructor at all.
3379 Affected file lib/silcutil/silchashtable.[ch].
3381 * Fixed ID Cache purging. It actually deleted the entries from
3382 the hash table after the data was freed. The hash table ended
3383 up comparing freed memory. The affected file is
3384 lib/silccore/silcidcache.c.
3386 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3388 * Fixed Irssi SILC client's KILL command's HELP syntax.
3390 * The USERS command now resolves the detailed user information
3391 if the userinfo field is missing. Affected file is
3392 lib/silcclient/command_reply.c.
3394 * Do not print error in silc_file_read if the read file does
3395 not exist. Just silently return NULL. Affected file is
3396 lib/silcutil/silcutil.c.
3398 * Fixed the silc_log_output to not wine about NULL filename
3399 and to not create some bogus " " filename. Affected file is
3400 lib/silcutil/silclog.c.
3402 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3404 * Fixed various printing bugs on the user interface in the
3405 Irssi SILC Client. Minor changes that were forgotten from
3408 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3410 * Fixed the configure.in.pre and the compilation and distribution
3411 environment to support the new autoconf 2.52. That version is
3412 now required to compile the CVS trunk.
3414 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3416 * Renamed function silc_parse_nickname to silc_parse_userfqdn
3417 to generally parse user@fqdn format strings. Affected file
3418 lib/silcutil/silcutil.c.
3420 * Added nickname_format and nickname_force_format fields to the
3421 SilcClientParams structure. The first one defines the format
3422 for the nicknames that the library will enforce if the receives
3423 multiple same nicknames. The second one is boolean value and
3424 can be used to force the library to always enforce the format
3425 to the nicknames regardles whether there are multiple nicknames
3426 or not. This configurable formatting was employed to flexibly
3427 support accessing multiple nicknames from the user interface.
3428 The userinterface can now set the nicknames to what ever format
3429 they prefer. Affected file lib/silcclient/silcapi.h.
3431 Added function silc_client_nickname_format to the file
3432 lib/silcclient/idlist.c. It performs the nickname formatting.
3434 Added new field `hostname´ to the SilcClientEntry context.
3435 It holds the hostname of the client. Affected file is
3436 lib/silcclient/idlist.h.
3438 * Irssi SILC Client sets the nicknames in nick@hostn format.
3439 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
3440 irssi/src/silc/core/silc-core.c.
3442 The WHOIS printing now also shows both the real nickname and
3443 the formatted nickname so that user knows how to access the
3444 user if there are multiple same nicknames cached. Affected
3445 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
3446 printing formatting too to take the hostname now as a separate
3447 argument. The Affected file is
3448 irssi/src/fe-common/silc/modules-formats.[ch].
3450 * Changed the silc_client_get_clients_local to accept the formatted
3451 nickname as argument. It accepts the real nickname too but the
3452 formatted nickname can be used to find the true entry from
3453 multiple entries. Affected file lib/silcclient/silcapi.h and
3454 lib/silcclient/idlist.c.
3456 * Added nickname_format_parse field to the SilcClientParams.
3457 It is a callback function provided by the application to parse
3458 the nickname out of the formatted nickname string. The library
3459 calls it to get the nickname from the formatted string. Since
3460 the application generally knows better the format of the nickname
3461 string it parses it instead of the library, even though library
3462 encodes the formatted string. If the callback function is not
3463 provided then the library will use the string as is. The
3464 affected file is lib/silcclient/silcapi.h.
3466 * All the nickname strings passed to the client library in
3467 commands are now expected to be formatted nickname strings.
3468 If the command does not support the formatted nickname string
3469 it will assume that the sent string is the actual nickname.
3470 Affected file lib/silcclient/command.c.
3472 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3474 * Added public key authentication support to OPER and SILCOPER
3475 commands in the client library. Affected file is
3476 lib/silcclient/command.c.
3478 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3480 * Changed the get_auth_methdod client operation to be asynchronous.
3481 It can be async if the application resolves the authentication
3482 method from the server during the negotiation. Added new
3483 SilcGetAuthMeth completion callback that the application will
3484 call after resolving the authentication method.
3486 Added function silc_client_request_authentication_method that
3487 the application can use to resolve the authentication method
3488 from the server. Added also SilcConnectionAuthRequest callback
3489 that the library will call after the server has replied. The
3490 application can call this function if it does not know the
3491 current authentication method.
3493 Affected files are lib/silcclient/client.c and
3494 lib/silcclient/silcapi.h.
3496 * The Irssi SILC client now automatically resolves the authentication
3497 method incase any configuration information is not present (and
3498 currently there never is). The affected file is
3499 irssi/src/silc/core/client_ops.c.
3501 * Fixed public key authentication from the client library.
3502 Affected file lib/silcclient/protocol.c. Changed also the
3503 protocol specification about the public key authentication in
3504 the connection authentication protocol. The actual data to be
3505 signed is now computed with a hash function before signing.
3507 * Fixed the public key authentication from the server as well.
3508 Affected file silcd/protocol.c.
3510 * Removed the mlock()'s from the memory allocation routines.
3511 Affected file lib/silcutil/silcmemory.c. The ./configure does
3512 not check anymore for the mlock(). Affected file is
3515 * Fixed USERS command in server to allow the execution of the
3516 command for private and secret channels if the client sending
3517 the command is on the channel. Affected file silcd/command.c.
3519 * Fixed silc_client_get_clients_local to return the clients
3520 count correctly. It could return wrong value. Affected file
3521 lib/silcclient/idlist.c.
3523 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3525 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
3526 types. The assembler optimizations seemed not to like 64-bit
3527 data types. The assmebler optimizations thus are now enabled
3528 also for BSD systems as opposed to only enable them for Linux.
3530 * Do not check for threads at all on BSD systems. Affected
3531 file configure.in.pre.
3533 * Removed -n and -h options from the Irssi SILC Client since
3534 they are not used in silc.
3536 * Fixed the prime generation to assure that the first digit
3537 of the generated random number is not zero since our conversion
3538 routines does not like number strings that starts with zero
3539 digit. If zero digit is seen the random number is regenerated.
3540 This caused some corrupted RSA keys when the zero first digit
3541 was met. Affected file lib/silcmath/silcprimegen.c.
3543 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3545 * Fixed WIN32 configuration in the ./configure script.
3546 Fixed to include xti.h on environments that has it.
3547 Patches by Carsten Ilchmann and andrew.
3549 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3551 * Changed the silc_id_create_client_id to be collision
3552 resistant. It is now assured that there cannot be created
3553 two same client ID's. I suspect that some weird bugs in
3554 the server were actually caused by duplicate Client IDs.
3555 Affected file silcd/serverid.[ch]. A router receiving
3556 new ID now also assures and informs the sending server
3557 if the ID caused collision.
3559 * Changed the silc_id_create_channel_id to also assure that
3560 there are no collisions.
3562 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3564 * Statement about ignoring the Mutual Authentication flag when
3565 performing rekey with PFS was a bit misleading. It is ignored
3566 if it was set in the initial negotiation, it cannot be even
3567 set in the rekey. Fixed in the ke-auth draft. Started the
3568 new versions of the protocol drafts in the doc/.
3570 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3572 * Fixed a bug in silc_client_command_identify_save when saving
3573 new channel information. The channel name was no duplicated
3574 and caused crash on exit. Affected file is
3575 lib/silcclient/command_reply.c.
3577 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3579 * Fixed the getkey command handling in the server. Send just
3580 empty OK reply to the sender if the key could not be fetched
3581 (but everything else was ok, like the key just was not available).
3582 Changed the public key parameter to optional in the protocol
3583 specs so that empty OK reply can be sent. Affected file
3586 Added a message to Irssi SILC client to tell to user if the
3587 server did not return a public key.
3589 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3591 * Fixed a channel key regeneration bug. It registered new
3592 timeout tasks exponentially until all system resources were
3593 used. Affected file silcd/server.c.
3595 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3597 * Added the SILC Document generator to the scripts/silcdoc.
3598 It can be used to generate the Toolkit Reference Manual out
3599 of the source tree. Internally it will also use the RoboDoc
3600 generator now imported in util/robodoc.
3602 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3604 * Added couple of return's in rekey protocol if error orccurred
3605 during the protocol. The execution must be terminated.
3606 Affected file silcd/protocol.c. Also, terminate the protocol
3607 always with timeout.
3609 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3611 * The client's Client ID was created initally from the wrong
3612 nickname (it could have been in format nick@host) in the
3613 silc_server_new_client. Affected file silcd/packet_receive.c
3615 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3617 * Added some SILC_LOG_ERROR's to various error conditions
3618 if client could not be added to ID cache. Affected files
3619 silcd/packet_receive.c and silcd/server.c.
3621 * When client's sock->user_data is freed, NULL also the
3622 client->router and client->connection pointers. Added check
3623 for these pointers being NULL to various places around the
3624 code. Affected file silcd/server.c.
3626 * Added client->data.registered == TRUE checks to various
3627 places around the code to assure that unregistered client's
3628 are not handled when it is not allowed. Affected file
3631 * Added `bool registered' fields to all
3632 silc_idlist_[server|client]_get_* routines to indicate whether
3633 the fetched client needs to be registered or not. Affected
3634 file silcd/idlist.[ch].
3636 * Add your own entry as registered to the ID cache in the
3637 server. Affected file server.c.
3639 * Fixed a bug in silc_server_new_server. The SilcServer was
3640 set as the new server's context instead of SilcServerEntry.
3641 This naturally caused some weird bugs.
3643 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3645 * Do not delete the channel rekey task when adding it
3646 for in silc_server_create_channel_key.
3648 * Changed the silc_server_create_channel_key to return
3649 TRUE or FALSE to indicate the success of the channel key
3652 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3654 * Fixed MSVC++ project files and added missing files to
3655 Makefiles under win32/.
3657 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3659 * Do not add TCP_NODELAY flag if the operating system
3660 does not have it defined. Affected files are
3661 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3663 * Fixed buffer overflow from Irssi SILC Client. Affected
3664 file irssi/src/fe-common/core/themes.c.
3666 * Fixed double free in client library in the file
3667 lib/silcclient/client.c when disconnecting from server.
3669 * Applied double free patch from cras to Irssi SILC client.
3670 Affected files irssi/src/core/[modules/expandos].c
3672 * Fixed the disconnection handling to Irssi SILC Client.
3673 The application must call silc_client_close_connection
3674 in ops->connect client operation in case of failure of
3675 the connection. Affected file is
3676 irssi/src/silc/core/client_ops.c.
3678 * Do not set sock->protocol to NULL in the function
3679 silc_client_close_connection after executing the protocol's
3680 final callback since the sock might not be valid anymore.
3681 Affected file lib/silcclient/client.c.
3683 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3685 * Do not enable SILC_THREADS if the linking with libpthread
3686 did not happen. Affected file configure.in.pre.
3688 * Added notion to protocol specification that server must
3689 verify the sent authentication payload with CMODE when
3690 setting the channel founder key. Implemented it to the
3691 server. Affected file silcd/command.c.
3693 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3695 * Added _EXTRA_DIST SILC distribution variable to the
3696 distributions file. It is used to conditionally add extra
3697 files or directories to the specific distribution. Affected
3698 files ./prepare, Makefile.am.pre and distributions.

3703 * Added README.WIN32 for instructions to compile the Toolkit
3706 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3708 * Fixed a double free in disconnection in the server. Affected
3709 file is silcd/server.c.
3711 * Fixed the lib/silcske/groups.c to work now also with GMP
3712 MP library. The string conversion did not work when using
3713 specific base and the base is indicated in the string as well.
3715 * Created win32/ directory which now includes MSVC++ specific
3716 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3717 It will appear only in the toolkit distribution
3719 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3721 * Changed the key material distribution function in case when
3722 the hash output is too short. The data is now concatenated
3723 a bit differently than it used to. Made the change to the
3724 SKE protocol specification.
3726 * Added better GMP detection to configure.in.pre. A patch
3729 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3731 * Fixed a minor bug in SKE that might cause some problem on
3732 some platforms. Affected file lib/silcske/silcske.c.
3734 * Added the cookie checking for initiator in the SKE. It checks
3735 that the responder returns the sent cookie unmodified. The
3736 affected file is lib/silcske/silcske.c. Added new SKE
3737 error type INVALID_COOKIE that can be sent during the
3738 negotiation. Fixed some memory leaks as well.
3740 * Added the "invalid cookie" error message to Irssi SILC client's
3743 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3745 * Added `task_max' field to the SilcClientParams to indicate
3746 the maximum tasks the scheduler can handle. If set to zero,
3747 default values are used. Affected file lib/silcclient/silcapi.h.
3749 * Fixed memory leaks in silc_client_close_connection. Affected
3750 file lib/silcclient/client.c.
3752 * Added silc_client_del_client_entry to client library to free
3753 all memory of given client entry. Affected file is
3754 lib/silcclient/idlist.[ch].
3756 * Added new functions silc_client_del_channel and
3757 silc_client_del_server to delete channel and server entries.
3758 Affected file lib/silcclient/[silcapi.h/idlist.c].
3760 * Removed silc_client_del_client_by_id from silcapi.h.
3762 * Fixed the INFO command to return the server's own info
3763 correctly when querying by Server ID. Affected file is
3766 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3768 * Removed the non-blocking settings in WIN32 code in the
3769 silc_sock_[read/write] and added SleepEx instead. Affected
3770 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3771 of input data is now checked with FIONREAD and ioctlsocket.
3773 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3775 * Call silc_schedule_task_del_by_context in the
3776 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3777 Affected file lib/silccore/silcprotocol.c.
3779 * Call silc_protocol_cancel for active protocols in the
3780 silc_server_close_connection if the funtion
3781 silc_server_free_sock_user_data has not been called.
3782 Affected file silcd/server.c.
3784 * Generic tasks cannot be deleted using the del_by_fd
3785 task deleting function since generic tasks does not match
3786 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3788 * Added a notion to SILCOPER help file that the SILCOPER works
3789 only on router server, not on normal server.
3791 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3793 * Added for WIN32 support for the new scheduler as well.
3794 Affected file lib/silcutil/win32/silcwin32schedule.c.
3796 * Fixed the SHA1 implementation to work on various platforms.
3798 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3800 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3801 API. It is part of the scheduler now. Everything else is
3802 as previously but some functions has changed their names.
3803 Checkout the lib/silcutil/silcschedule.h for the interface.
3804 Updated all applications to use the new interface. Affected
3805 files are lib/silcutil/silcschedule.[ch].
3807 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3809 * Found a bug in the SKE implementation. The HASH value,
3810 specified by the protocol, was not computed correctly. The
3811 public key of the responder was not added to the computation
3812 even though it is mandatory. Affected file lib/silcske/silcske.c.
3813 This unfortunately causes incompatibilities with older
3814 clients and servers.
3816 * Added WIN32 specific network init and uninit functions:
3817 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3818 the Winsock2. Affected file lib/silcutil/silcnet.h and
3819 lib/silcutil/win32/silcwin32net.c.
3821 * Set the socket always to nonblocking mode on WIN32 after
3822 reading data or writing data. Affected file is
3823 lib/silcutil/win32/silcwin32sockconn.c.
3825 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3827 * Fixed various compilation problems under WIN32. Affected
3828 files lib/silcutil/win32/silcwin32thread.c and
3829 lib/silcutil/win32/silcwin32schedule.c.
3831 * Removed all _internal.h #includes from public header
3832 files. Internal headers must never be included from
3835 Removed also the lib/silcske/payload_internal.h file.
3837 * All include files that may be needed (public and some others
3838 included by the public headers) by application developers are
3839 now copied to the ./includes directory. It does not copy any
3840 internal headers. Affected file Makefile.defines.pre and all
3841 Makefile.am's under lib/ and subdirs.
3843 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3845 * Do not change the ~/.silc directory's permissions automatically.
3846 Affected file irssi/src/silc/core/clientutil.c.
3848 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3850 * Do not cancel the protocol in silc_server_close_connection
3851 it might cause recursion. Now cancelled in the function
3852 silc_server_free_sock_user_data. Affected file silcd/server.c.
3854 * Fixed the silc_server_remove_clients_by_server to regenerate
3855 the channel keys correctly finally. Added also new function
3856 silc_server_remove_clients_channels to actually do it.
3857 Affected file silcd/server.c.
3859 * Fixed the silc_server_new_channel to not crash by giving
3860 wrong router to the new channel. Affected file is
3861 silcd/packet_receive.c.
3863 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3865 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3866 which is given as argument to the silc_client_alloc now.
3867 It can be used to configure the client and set various parameters
3868 that affect the function of the client.
3870 * The USERS command in server did not check whether the channel
3871 is private or secret. Affected file silcd/command.c.
3873 * Added new argument to the USERS command in protocol specification.
3874 The USERS command now can take the channel name as argument
3875 as well. Added support for this in client and server and
3876 updated the protocol specs.
3878 * Completed the GETKEY command in client. It can be now used
3879 to fetch also servers public key not only some clients.
3880 Affected files lib/silcclient/command[_reply].c.
3882 * Added silc_client_get_server to return server entry by the
3883 server name. Affected files lib/silcclient/silcapi.h and
3886 * Redefined the IDENTIFY command in protocol specification to be
3887 more generic. It now can be used to query information about
3888 any entity in the SILC Network, including clients, servers and
3889 channels. The query may be based either the entity's name
3890 or the ID. Added support for this in both client and server.
3892 Affected files silcd/command.c and lib/silcclient/command.c
3893 and command_reply.c.
3895 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3896 the _from_client and _from_server functions. Affected file
3899 * Added silc_client_get_channel_by_id_resolve to the file
3900 lib/silcclient/silcapi.h to resolve channel information by
3901 its ID. Added also silc_client_get_channel_by_id that
3902 does not resolve it from the server.
3904 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3906 * Added SilcServerEntry context into the client library
3907 to represent one server. The INFO command now allocates
3908 these to save the resolved server info. For now on the
3909 client library will also keep information about servers,
3910 connected and resolved with INFO.
3912 The INFO command now allocates the SilcServerEntry context
3913 and saves the server info there. The COMMAND_REPLY in
3914 the INFO now returns the parameters to application in
3915 same order as defined in the protocol specification.
3917 The entries are cached in the client->server_cache.
3919 * The INFO command is now issued after received the Client ID
3920 from the server. Affected file lib/silcclient/client.c.
3922 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3923 to the application as the mode changer might be server.
3924 It is guaranteed that NULL is not returned anymore to the
3925 application. Affected file lib/silcclient/client_notify.c.
3927 The ID Type is now also passed to the application so that
3928 it can check whether the returned entry is SilcClientEntry
3931 Added new function silc_client_get_server_by_id to return
3932 the server entry by ID. Affected files are the
3933 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3935 * Do not create the channel in the Irssi SILC Client when issuing
3936 the JOIN command but when received the sucessful JOIN command
3937 reply. Otherwise the channel might get created even though we
3938 could not join it. The Affected file is
3939 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3941 * Fixed a channel joining bug in router. The router must also
3942 check the channel modes, invite and ban lists etc. when serving
3943 the JOIN command sent by normal server. Affected file is
3944 silcd/command.c. The router now resolves the client's
3945 information from the server who sent the JOIN command if it
3946 does not know it, and processes the JOIN command only after
3949 * Changed the SilcCommandCb to take new argument; void *context2.
3950 Affected file lib/silccore/silccommand.h
3952 The second argument in the command callbacks in the server now
3953 includes the SilcServerCommandReplyContext if the command was
3954 called as pending command callback from the command reply.
3955 Otherwise it is NULL. When called as pending the status of the
3956 command reply will be checked and if it was erronous the
3957 error will be sent to the original sender of the command.
3958 This way the client always receives the error messages even
3959 though the server was actually the one who received the error
3960 when it resent the command to router, for example. Affected
3961 files silcd/command[_reply].[ch].
3963 * Fixed sending WHOWAS command's error message to client if
3964 the requested client could not be found. It was missing.
3967 * Changed the CMODE and CUMODE commands reply arguments in the
3968 protocol specification. The Channel ID is now sent in both
3969 of the commands to identify the channel. Implemented this
3970 new feature to the client and server. Affected files
3971 lib/silcclient/command_reply.c and silcd/command.c.
3973 * Made better checks for invite and ban lists in the JOIN
3974 command in server. Affected file silcd/command.c.
3976 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3978 * The server now performs the incoming host IP/DNS lookup
3979 using the silc_socket_host_lookup and thus does not block
3980 the server anymore. Affected file silcd/server.c.
3982 * Completed the multi-thread support for SILC Scheduler in
3983 the lib/silcutil/silcschedule.c.
3985 * Fixed the configure.in.pre to detect the pthread correctly
3988 * Fixed a deadlock in silc_task_queue_wakeup in the file
3989 lib/silcutil/silctask.c.
3991 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3993 * Added new function silc_schedule_wakeup that is used in
3994 multi-threaded environment to wakeup the main thread's
3995 schduler. It needs to be used when a thread adds a new task
3996 or removes a task from task queues. After waking up, the
3997 scheduler will detect the task queue changes. If threads
3998 support is not compiled in this function has no effect.
3999 Implemented the wakeup mechanism to both Unix and WIN32
4000 systems. Affected files are lib/silcutil/silcschedule.[ch],
4001 lib/silcutil/unix/silcunixschedule.c and the
4002 lib/silcutil/win32/silcwin32schedule.c.
4004 * Added new function silc_task_queue_wakeup to wakeup the
4005 scheduler by the specified task queue. Affected file
4006 lib/silcutil/silctask.[ch].
4008 * The silc_socket_host_lookup_start now wakes up the scheduler
4009 after adding the timeout task. Affected file is
4010 lib/silcutil/silcsockconn.c.
4012 * The silc_socket_host_lookup is synchronous now if the threads
4013 support is not compiled in. However, the callback is still
4014 called asyncronously through the scheduler, anyway. Affected
4015 file lib/silcutil/silcsockconn.c.
4017 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4019 * Added new function silc_socket_host_lookup to perform
4020 asynchronous IP and FQDN lookups for the socket connection.
4021 Affected files lib/silcutil/silcsockconn.[ch].
4023 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4025 * Added SILC_MUTEX_DEFINE to define the mutex on environments
4026 that may or may not compile the mutex support in.
4028 Changed the silc_mutex_alloc interface. It allocates the
4029 mutex now to the sent pointer and returns TRUE or FALSE.
4031 Affected file lib/silcutil/silcmutex.h.
4033 * Wrote the SILC Task Queue interface to support multi-threads.
4034 Affected file lib/silcutil/silctask.[ch].
4036 * Wrote the SILC Scheduler to support multi-threads. Affected
4037 file lib/silcutil/silcschedule.c.
4039 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4041 * Implemented the SILC Mutex API and SILC Thread API for WIN32
4042 in lib/silcutil/win32/.
4044 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4046 * Defined SILC Mutex API and SILC Thread API and implemented
4047 them for Unix. Affected files are
4048 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
4049 lib/silcutil/unix/silcunixmutex.c and
4050 lib/silcutil/unix/silcunixthread.c.
4052 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4054 * Fixed the silc_server_remove_clients_by_server's channel
4055 key re-generation. The hash table handling was incorrect
4056 and would not work with many channels. Affected file is
4059 * Fixed some memory leaks around the server code.
4061 * Rewrote the silc_server_get_users_on_channel to support IPv6
4062 based Client ID's. Affected file silcd/server.c.
4064 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
4065 specification. However, a separate document must be written
4066 to define the detailed signing procedure and the payload
4067 associated with the flag. Defined the flag to the
4068 lib/silccore/silcchannel.h as well.
4070 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4072 * Changed the dynamic tables to static size tables in the
4073 lib/silccrypt/silchmac.c.
4075 * Removed GCC dependencies from the code. A patch by cras.
4077 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4079 * Do not show the error "Error receiving packet bla bla"
4080 in server if it really was not an error (-2 means that reading
4081 is pending). Affected file silcd/server.c.
4083 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4085 * Fixed a possible crash in silc_server_remove_clients_by_server
4086 in silcd/server.c. Fixed there also some memory leaks.
4088 * Fixed the silc_idlist_replace_client_id. It could replace
4089 wrong key in the hash table. Affected file silcd/idlist.c.
4091 * Do not check whether there are global users on the channel
4092 if the channel->global_users is FALSE. Affected functions
4093 silc_server_remove_from_one_channel and
4094 silc_server_remove_from_channels in silcd/server.c. Also,
4095 do not check if the removed client is local as we can be
4096 sure that global client was not removed from the channel
4097 and checking for global users is not needed.
4099 * The silc_server_remove_clients_by_server now re-generates
4100 the channel keys correctly for those channels that had
4101 clients removed from them. Affected file silcd/server.c.
4103 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4105 * Found the reason of random crashes in the server. We weren't
4106 ignoring the SIGPIPE signal (which can be sent in write())
4107 and it crashed the server. Affected file silcd/silcd.c.
4109 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4111 * Assure that sock->user_data is not NULL in the function
4112 silc_server_packet_send in silcd/packet_send.c.
4114 * Disconnect the remote connection if it could not be added
4115 to any ID lists in the server. The affected file is
4118 * Check in silc_server_packet_send[_real/dest] that the
4119 socket is not disconnecting and ignore the data if it is.
4120 Affected file silcd/packet_send.c.
4122 * Define inline to __inline on native WIN32 compilation.
4123 Affected file includes/silcwin32.h.
4125 * Added some explicit type casts for inline code since MSVC
4126 require them. Affected files lib/silcutil/silcbuffer.h,
4127 lib/trq/silcdlist.h and lib/trq/silclist.h.
4129 * Print warning in log files from now on if the packet
4130 decryption fails. Affected file silcd/server.c.
4132 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4134 * Changed the `say' client operation's interface to accept
4135 new `type' argument to indicate the type of the message sent
4136 by the library. The application may filter the library's
4137 messages according the type. The affected file is the
4138 lib/silcclient/silcapi.h.
4140 * Added two new functions to lib/silcclient/silcapi.h:
4141 silc_client_del_client and silc_client_del_client_by_id.
4142 Affected file lib/silcclient/idlist.c.
4144 * Moved the clientincludes.h from includes/ to silc/ and
4145 serverincludes.h from includes/ to silcd/.
4147 * The modes for the CMODE and CUMODE are now passed as
4148 uint32 for application with COMMAND_REPLY. The affected
4149 file is lib/silcclient/command_reply.c.
4151 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4153 * /WHOIS without arguments shows client's own information.
4154 Affected file lib/silcclient/command.c.
4156 * Changed PING to not accept any arguments. The specs
4157 says that client can ping only the connected server so
4158 requiring an argument is not needed. Affected file is
4159 lib/silcclient/command.c.
4161 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4163 * Fixed a fatal bug in private message sending and reception
4164 encryption and decryption when using private message keys.
4165 The implementation was incorrect and did not follow the
4166 specification. It causd that some of the message were
4167 lost since it did not use the sending and receiving keys
4168 as the protocol suggests. This has been fixed and will cause
4169 incompatibilities with older clients when sending private
4170 message encrypted with private message keys. Affected files
4171 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
4172 and various other in Irssi SILC Client.
4174 Added `responder' boolean argument to the functions
4175 silc_client_add_private_message_key[_ske] to indicate when
4176 the key is added as responder or initiator of the key
4179 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4181 * Removed the silc_ske_check_version function and created
4182 a SilcSKECheckVersion callback. Added also a function
4183 silc_ske_set_callbacks that is now used to set all SKE
4184 callbacks. The callback functions are not given to
4185 the SKE functions anymore, but this function is used to
4188 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
4190 * Added `silc_version' argument to the silc_client_alloc
4191 to define the version of the application for the library.
4192 The library will use the version string to compare it
4193 against the remote host's (usually a server) version
4194 string. Affected file lib/silcclient/silcapi.h
4196 * Added the KE protocol context to Key Agreement context
4197 in client library so that we can abort the SKE if it
4198 is in process when we get timeout. Affected file is
4199 lib/silcclient/client_keyagr.c.
4201 * Do not resolve the client ID forever if it returns in the
4202 first time that such client does not exist. This was done
4203 for example with private message. Affected file is
4204 lib/silcclient/client_prvmsg.c.
4206 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4208 * Do not add regex.h for WIN32. The affected file
4209 includes/silcincludes.h.
4211 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
4212 not work yet 100%. It generates the DLL's automatically
4213 when compiling with --with-win32 under cygwin.
4215 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4217 * lib/contrib/regex.c is not compiled on WIN32.
4219 * Added silc_net_get_socket_opt function to the
4220 lib/silcutil/silcnet.h.
4222 * Added includes/silcwin32.h for WIN32 specific includes
4225 * Do not use ptime structure or any of the posix process
4226 functions on WIN32 in lib/silccrypt/silrng.c.
4228 * Added silc_gettimeofday to provide generic function
4229 for struct timeval on all platforms. Added the function
4230 to lib/silcutil/silcutil.h.
4232 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4234 * Moved the lib/silccore/silcsockconn.[ch] to the utility
4235 library as they clearly belong there. As a plus side we
4236 can make the actual socket connection routines platform
4239 Added also new generic function silc_socket_read and
4240 silc_socket_write (that used to be silc_packet_[read/write].
4241 The implementation of these are platform specific.
4243 * Added WIN32 specific routines of silc_socket_[read/write]
4244 to lib/silcutil/win32/silcwin32sockconn.c.
4246 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4248 * Added preliminary support for native WIN32 compilation under
4249 cygwin (using the -mno-cygwin option for GCC) to the
4250 ./configure.in.pre. The --with-win32 now prepares the
4251 compilation for native WIN32.
4253 * Rewrote the SILC Scheduler interface in the file
4254 lib/silcutil/silcschedule.h. The scheduler is now context
4255 based and does not have anymore any global static scheduler.
4256 Moved the Unix scheduler to the lib/silcutil/unix/ directory
4257 and created lib/silcutil/win32 directory for WIN32 based
4260 * Added Unix specific network routines to the
4261 lib/silcutil/unix/silcunixnet.c and the old
4262 lib/silcutil/silcnet.c includes now only generic routines.
4264 Added WIN32 specific network routines to the
4265 lib/silcutil/win32/silcwin32net.c.
4267 * Added Unix specific utility functions from the
4268 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
4270 * Added WIN32 SILC Scheduler to the file
4271 lib/silcutil/win32/silcwin32schedule.c. The code is of course
4274 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4276 * Do not handle JOIN notify in the server if the target client
4277 is not registered (idata->registered == FALSE). The affected
4278 file is silcd/packet_receive.c.
4280 * Update the nickrec->founder in event_cumode in the Irssi SILC
4281 client. Affected file irssi/src/silc/core/silc-channels.c.
4283 * Fixed the CUMODE_CHANGE notify handling in the server when
4284 server and router are announcing their clients on channels.
4285 Now the mode changes are saved and notified correctly. The
4286 affected file is /silcd/packet_receive.c.
4288 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
4289 They really did not replace the cache entry in the ID Cache.
4290 Now they do that. Affected file silcd/idlist.c.
4292 * Fixed the KICK notify handling in the Irssi SILC client to
4293 update the channel records so that the kicked client does not
4294 appear to be on the channel. The affected file is
4295 irssi/src/silc/core/silc-channels.c.
4297 * Always update the conn->current_channel when executing command
4298 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
4300 * Fixed the KILL notify handling in Irssi SILC client to remove
4301 the killed client on all channels.
4303 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4305 * Fixed the silc_parse_command_line to remove extra spaces
4306 from the start and end of the arguments. Affected file is
4307 lib/silcutil/silcutil.c.
4309 * Cancel and free any active protocol in the function
4310 silc_server_close_connection. Affected file silcd/server.c.
4312 * Cancel and free any active protocol in the function
4313 silc_client_close_connction. Affected file is
4314 lib/silcclient/client.c.
4316 * Do not execute the KILL command for clients that are in
4317 history (ie. they are not in the network). Affected file is
4320 * Fixed KILL notify handling, client does not crash anymore.
4321 Affected file irssi/src/silc/core/silc-channels.c.
4323 * Reduced the default packet buffer size from 2048 to 1024 in
4324 lib/silccore/silcpacket.c.
4326 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
4327 counter to the SKE context that is incresed when the SKE library
4328 performs async operation outside the library. If the outside
4329 process frees the SKE context and FREED status will be set
4330 and the library will detect after the sync operation that the
4331 libary is freed. The affected files are
4332 lib/silcske/silcske[_status].[ch].
4334 * Resolve the client entry information in the function
4335 silc_client_channel_message to assure that NULL pointer is not
4336 passed as client entry to the application. */
4338 * Fixed the task timeout calculation to assure that there is
4339 never negative timeouts. The affected file is
4340 lib/silcutil/silcschedule.c.
4342 * Fixed the channel user mode notification sending in server.
4343 It was sent point-to-point to the router (or to server by router)
4344 but it needs to be destined to a channel. The routines now
4345 supports sending the channel user mode notifys to the channels
4346 when announcing clients and channels. Affected files are
4347 silcd/server.c and silcd/packet_receive.c.
4349 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
4350 It did not actually replace the old channel entry in the cache.
4351 Affected file lib/silcclient/client_notify.c.
4353 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4355 * Fixed a possible crash in silc_packet_send_prepare. It now
4356 assures always that there is enough space in the buffer and
4357 at the tail area of the buffer (for MAC).
4359 Fixed the inbound buffer reallocation in silc_packet_read.
4360 It was old code and did not handle the reallocation correctly.
4363 The affected file is lib/silccore/silcpacket.c.
4365 * Fixed buffer overflow in silc_parse_nickname in the file
4366 lib/silcutil/silcutil.c.
4368 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4370 * make install generates new server keys only if there is not
4373 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4375 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
4376 Added check that if the NOREPLY is set then we will not send
4377 the away message. This avoids infinite loop of away messages
4378 if both clients are away. The affected file is
4379 lib/silcclient/client_prvmsg.c.
4381 * Fixed client crash if /NICK was given without arguments.
4382 Affected file lib/silcclient/command.c.
4384 * Server does not send the invite list in INVITE command back
4385 to the client if the list was not altered. Added this notion
4386 to the protocol spec as well. Affected file silcd/command.c.
4388 Fixed possible crash in INVITE command by checking the
4389 value of silc_server_get_client_route command.
4391 * Fixed the INVITE notify type handling. The arguments are now
4392 taken in correct order and client does not crash. The affected
4393 file is irssi/src/silc/core/silc-channels.c.
4395 Removed the "Inviting xxx to channel" message from the
4396 client library away and let the application handle it.
4397 Affected file lib/silcclient/command.c. Added that message
4398 to Irssi SILC client's message formats.
4400 * Fixed CMODE command crash in client. It now checks the
4401 amount of arguments correctly and does not crash. The affected
4402 file is lib/silcclient/command.c.
4404 * Do not create new channel automatically in silc_channels_join
4405 but check whether the channel by that name already exists.
4406 Affected file irssi/silc/core/silc-channels.c.
4408 * Do not send the SERVER_SIGNOFF to router if the disconnected
4409 entity was the router. Affected file silcd/server.c.
4411 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
4412 SILC client as it was missing from there.
4414 Added the handling of the KICK notify to the Irssi SILC client
4415 as it was missing. Added "you have been kicked" message to
4416 Irssi SILC client's message modules formats.
4418 Added the handing of the KILL notify to the Irssi SILC client
4419 as it was missing. Added the kill message module formats
4422 The affected file is irssi/src/silc/core/silc-channels.c.
4424 * The router did not save the channel mode the server announced.
4425 Affected file silcd/packet_receive.c.
4427 * Fixed a possible crash in INFO command in server. If the
4428 server did not provide the server info it crashed. Affected
4429 file silcd/command.c.
4431 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4433 * Fixed the GETKEY command in the server to check also the
4434 global list. Otherwise the GETKEY would not work correctly
4435 in normal SILC server. Affected file silcd/command.c.
4437 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4439 * Fixed GETKEY crash, it crashed if the command did not succseed.
4441 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4443 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
4444 is now real and not just an macro interface to GMP.
4446 Removed the entire GMP from the source tree and imported new
4447 NSS MPI library instead. Reason for removing GMP is that it is
4448 extremely large and compiles extremely slow. The NSS MPI
4449 is only a few files and compiles in less than 10 seconds.
4450 The speed is also about the same as GMP. The MPI is imported
4451 to lib/silcmath/mpi.
4453 If the system has GMP installed we will still use the GMP.
4454 If it is not then the NSS MPI will be compiled.
4456 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4458 * Merged a long nickname (127 characters long) crash bugfix from
4459 Irssi CVS tree. Affected file irssi/src/core/misc.c.
4461 * Merged a freed memory reference bugfix from Irssi CVS tree.
4462 Affected file irssi/src/core/commands.c.
4464 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4466 * Added the server's public key sving and verification to the
4467 server when performing the SKE. This was missing and the
4468 remote server's (or router's) public key was accepted without
4469 checking whether we have it previously or trust it at all.
4470 Affected file silcd/protocol.c.
4472 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4474 * Check in the silc_server_timeout_remote if protocol is active
4475 and make sure that the protocol's final callback is called so
4476 that all memory if freed. Affected file silcd/server.c.
4478 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4480 * silc_server_whois_send_reply crashed the server if the nickname
4481 was 127 characters long. Affected file silcd/command.c.
4483 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4485 * Added sanity check to the silc_server_new_client. If the hostname
4486 is provided inside username then check that the provided hostname
4487 really is the same as the resolved one. If the hostname was not
4488 resolved then check it from the public key. Affected file is
4489 silcd/packet_receive.c.
4491 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
4492 if the server disconnected us and the connection is not valid
4493 anymore. Affected file irssi/src/silc/core/silc-channels.c.
4495 * Moved the silc_client_[chmode|chumode|chumode_char] away from
4496 the library to the lib/silcutil/silcutil.[ch].
4498 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4500 * Close log file after open. Affected file
4501 lib/silcutil/silclog.c.
4503 * Check whether sock == NULL in silc_client_send_packet and return
4504 if it is. Affected file lib/silcclient/silcclient.c.
4506 * Check rec->entry == NULL in the Irssi SILC Client before
4507 sending the channel message. Affecte file is
4508 irssi/src/silc/core/silc-servers.c.
4510 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4512 * Merged a splitted window bugfix from Irssi CVS tree. The
4513 affected file is irssi/src/fe-text/textbuffer-view.c.
4515 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
4516 It did not print nickname.
4518 * Improved the distributions system a bit.
4520 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4522 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
4523 irssi/src/fe-text/gui-window.c.
4525 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
4526 to in-active server. The affected file is
4527 irssi/src/silc/core/client_ops.c.
4529 * Resolve the client in USERS command reply if the entry does
4530 not have username resolved. The affected file is
4531 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
4532 command to WHOIS command to really resolve stuff. The USERS
4533 is not used any more in any critical section so WHOIS can
4534 be used even though it might be slower than IDENTIFY.
4536 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
4539 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4541 * Changed the protocol API a bit more consistent in the
4542 lib/silccore/silcprotocol.[ch].
4544 * Changed the following headers to ROBODoc format:
4546 lib/silccore/silcpayload.h
4547 lib/silccore/silcprotocol.h
4548 lib/silccore/silcsockconn.h
4550 All core library headers are now formatted.
4552 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4554 * Fixed a bug in Irssi SILC client; do not show that you are
4555 server/router operator if you really are not. Affected file is
4556 irssi/src/silc/core/client_ops.c.
4558 * Renamed silc_command_free_payload to silc_command_payload_free.
4559 Affected file lib/silccore/silccommand.h
4561 * Added silcmath.h to include the prototoypes of various routines
4562 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
4565 * Changed the following headers to ROBODoc format:
4567 lib/silccore/silcchannel.h
4568 lib/silccore/silccommand.h
4569 lib/silccore/silcid.h
4570 lib/silccore/silcidcache.h
4571 lib/silccore/silcmode.h
4572 lib/silccore/silcnotify.h
4573 lib/silccore/silcpacket.h
4574 lib/silcmath/silcmath.h
4576 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4578 * Added checking to the server code not to start the server if
4579 ciphers and stuff are not configured properly. Affected files
4580 silcd/serverconfig.[h] and silcd/server.c.
4582 * Changed the layout of the header files of the public interfaces
4583 in the SILC libraries. The new layout supports ROBODoc
4584 documentation tool (and some others) so that it is easy to create
4585 a library reference manual. All the other headers and source
4586 code must still follow the CodingStyle document. Also source
4587 code must not include these ROBODoc stuffs, only the headers.
4588 Furthermore, all public interface headers must now be named
4589 by using `silc' prefix, example: silcapi.h, silccipher.h.
4590 Some files were renamed due to this. All the other headers
4591 must not be used as public interfaces. I will update the
4592 CodingStyle document later. Changed following headers, so far:
4594 lib/silcclient/silcapi.h
4595 lib/silccore/silcauth.h
4596 lib/silccore/silcprivate.h
4597 lib/silccrypt/silcdh.h
4599 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4603 * Removed silc_client_packet_send_flush from the client library
4604 as it is not needed. Affected file lib/silcclient/client.[ch].
4606 * Added printing of message of unresolved authentication method
4607 to the Irssi SILC client. Added it to the module formats.
4608 Removed the same message from the client library.
4610 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4612 * Added new distribution feature, DISTLABEL. Every distribution
4613 can define own preprocessor label that can be used in the
4614 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
4615 file distributions, acconfig.h.pre and prepare.
4617 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4619 * Added Makefile.defines_int to include the actual definitions
4620 for Makefile.defines.in. Tested the new distribution system,
4621 created distributions and tested installation.
4623 * Added AWAY message printing to the Irssi SILC client. Added
4624 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
4626 * Added SCONNECT command to call the SILC's CONNECT command.
4627 Cannot use CONNECT directly since Irssi uses that internally.
4628 Affected file irssi/src/silc/core/silc-servers.c.
4630 Added ACTION local command. It is same as ME command but takes
4631 the channel as mandatory argument.
4633 Rewrote some of the Irssi's help files to suite for SILC
4636 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4638 * Added Makefile.defines[.in] that should for now on be included
4639 in all Makefile.am file in the source tree. That file includes
4640 all common compilation definitions for SILC source tree.
4642 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4644 * Minor changes to the ./prepare script to change the package
4645 name according the distribution name to the configure.in.
4647 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4649 * Created new distribution system. Added file `distributions'
4650 that defines all the distributions that can be created out of
4651 the SILC source tree. The ./prepare script now reads that
4652 file to determine how to prepare the distributions. The
4653 first argument to the ./prepare is the name of the distribution
4654 and second is the version of the distribution. If given
4655 without arguments it creates the default (toolkit) distribution
4656 with the default version (defined in ./prepare).
4658 All Makefile.am files that are subject to the distributions
4659 are now named as Makefile.am.pre. These are ./Makefile.am
4660 and lib/Makefile.am. Others may be changed later.
4662 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4664 * Added invite list, ban list, some key management and connection
4665 error message printing to module formats in the Irssi SILC client.
4667 * Added new silc_client_set_away_message to set the away message
4668 that is back to the person who sent private message. The
4669 affected file lib/silcclient/silcapi.h and the
4670 lib/silcclient/client_prvmsg.c.
4672 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4674 * Fixed the private message sending in the Irssi SILC client,
4675 added local command KEY to the Irssi SILC client.
4677 Added key management and key agreement message formats to the
4678 irssi/src/fe-common/silc/module-formats.[ch].
4680 Added USERS (alias WHO) printing, server/router operator
4681 indication and LIST command printing to the module formats.
4683 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4685 * Fixed channel joining notify handling, cumode notify handling
4686 from Irssi SILC client.
4688 * Added SILC specific module-formats to the Irssi SILC client so
4689 that SILC specific message hilighting, colors etc is possible.
4690 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4692 Added channel mode, channel user mode, actions, notices,
4693 whois and whowas printing to the the module-formats.c.
4695 * Fixed a bug in channel deletion in the server. The channel
4696 is not left to the cache even if the channel founder auth mode
4697 is set when there are no users anymore on the channel. Affected
4698 file silcd/server.c.
4700 * The silc_net_localhost now resolves the entire hostname including
4701 the domain name. Affected file lib/silcutil/silcnet.c.
4703 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4705 * Changed the ask_passphrase client operation to be ascynchronous.
4706 It has now a completion callback and a context that the
4707 application must call after it has got the passphrase from
4708 the user. Affected files lib/silcclient/silcapi.h,
4709 lib/silcclient/protocol.c, lib/silcclient/command.c and
4712 Added SilcAskPassphrase callback that the application calls
4713 to deliver the passphrase to the library.
4715 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4716 The public key verification and especially a certificate
4717 verification is asynchronous procedure.
4719 Added new SILC_SKE_STATUS_PENDING status to indicate the
4720 request is pending and a callback will be called to finalize
4723 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4724 indicate that remote end did not send its public key (or
4725 certificate), even though we require it. Added check for this
4726 condition in the SKE. This was a security bug, now fixed.
4728 Defined new SilcSKEVerifyCbCompletion callback that is called
4729 when the verification process is completed.
4731 The affected files lib/silcske/silcske_status.h and
4732 lib/silcske/silcske.[ch].
4734 * Changed the verify_public_key client operation to be async
4735 as well. Defined SilcVerifyPublicKey callback that is used to
4736 indicate the success of the public key verification process.
4738 Changed the server and client to use the new async client
4741 * Changed the Irssi SILC client's internal scheduler to be called
4742 twice as many times as it used to be. As a result the client
4743 should be a bit faster now. Affected file is
4744 irssi/src/silc/core/silc-core.c.
4746 * Added support to Irssi SILC client of asynchronous public key
4747 verification and passphrase inquiry. Affected file is
4748 irssi/src/silc/core/silc-core.c.
4750 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4752 * Do not say "You have left channel %s" in client library.
4753 Moved it to the application. Affected files are
4754 lib/silcclient/command.c and silc/client_ops.c.
4756 * Fixed silc_client_get_clients. Command context was not
4757 duplicated and was freed memory in the callback. Affected
4758 file lib/silcclient/idlist.c.
4760 * Do not say "you are now talking..." on JOIN command in the
4761 client library. The appliation must handle it.
4763 * Do not say ".. changed topic to" in command reply in the
4764 client libary. The application must handle it.
4766 * Fixed TOPIC command sending in the client library.
4768 * Fixed a memory leak in silc_client_command_free in the file
4769 lib/silcclient/command.c.
4771 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4773 * Imported a modified version of Irssi client to the source tree.
4774 The Irssi will be used to create a new client called
4775 Irssi SILC. Imported to irssi/.
4777 Added silc_core_init_finish function to the Irssi. Affected
4778 file irssi/configure.in.
4780 A lot changes in the Makefile.ams around the irssi tree.
4782 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4784 * Do not rehash if the new size is same as the old size of the
4785 hash table, in the silc_hash_table_rehash*. The affected file
4786 lib/silcutil/silchashtable.c.
4788 * Replaced hash_table_del_by_context calls from the server
4789 (when channel->user_list and client->channels) to the
4790 hash_table_del as it is sufficient and faster.
4792 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4794 * Added silc_hash_table_list, silc_hash_table_get and the
4795 SilcHashTableList structure to provide an alternative way to
4796 traverse the hash table. The affected files are
4797 lib/silcutil/silchashtable.[ch].
4799 * Changed the server's idlist routines to use the hash table
4800 routines to optimize the code.
4802 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4804 * Replaced the client entry's `channel' list and channel entry's
4805 `user_list' list to hash tables for optimized lookup. Changed
4806 the code to use the hash table interface around the code.
4807 Affected file lib/silcd/idlist.[ch].
4809 * Added `auto_rehash' boolean argument to the function
4810 silc_hash_table_alloc to indicate whether the hash table should
4811 auto-rehash when it thinks is appropriate time. It will
4812 increase the hash table size if the there is twice as much
4813 entries in the table than the size of the table, and will
4814 decrease the size if there are twice as less entries than
4815 the size of the table.
4817 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4819 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4821 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4823 * silc_idcache_purge_by_context deletes the entry now by context
4824 as it is supposed to do. Affected file lib/silccore/idcache.c.
4826 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4827 client is not anymore valid (WHOWAS givens the info) and not
4828 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4830 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4832 * Removed the `data' and `data_len' arguments from the ID Cache
4833 interfaces and added `name' argument. ID Cache does not handle
4834 anymore the binary data only a names associated with given ID.
4836 * When hashing a Client ID with silc_hash_id the entire ID is
4837 not hashed anymore, instead only the hash of the Client ID is
4838 hashed. This way we can access the Client ID from the cache
4839 with Client ID but with the hash of the ID (which is a hash of
4840 the nickname) as well without any difference in performance.
4842 Added also silc_idcache_find_by_id_one_ext to do one on one
4843 searching when we have the actual ID. Added also function
4844 silc_hash_client_id_compare. The affected files are
4845 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4847 * When hashing the name associated with a ID it is always done
4848 in lowercase. This way we can access the cache without worrying
4849 about case-sensitivity, even though, for example nicknames are
4852 * Fixed a bug in server with channel message sending. It put
4853 wrong ID type as destination ID. The affected file
4854 silcd/packet_send.c.
4856 * silc_idcache_del_by_context now deletes from all hash tables
4857 by context. Affected file lib/silccore/idcache.c.
4859 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4861 * Changed the client library to use the new ID Cache interface.
4862 Changes around the source tree.
4864 * Added silc_hash_table_rehash_ext to rehash with specific
4865 hash function. Affected file lib/silcutil/silchashtable.[ch].
4867 * Added silc_hash_string_compare to compare two strings in the
4868 hash table. Affected file lib/silcutil/silcutil.[ch].
4870 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4872 * Added new function silc_idcache_del_by_context into the
4873 lib/silccore/idcache.[ch].
4875 * Changed the server's ID list routines to use the new ID Cache
4876 interface. Changes around the source tree.
4878 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4880 * Added silc_hash_table_del[_by_context]_ext functions in to the
4881 lib/silcutil/silchashtable.[ch].
4883 Removed silc_hash_table_find_all* routines and added new
4884 silc_hash_table_find_foreach to replace them.
4886 Added silc_hash_table_replace_ext function as extended
4887 replacing function. Separated the simple hash table interface
4888 from the extended hash table interface in the file
4889 lib/silcutil/silchashtable.h.
4891 * Fixed minor bugs and changed it to use some of the new
4892 hash table functions in lib/silccore/idcache.c
4894 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4896 * Added new function silc_hash_table_find_all to return all keys
4897 in the hash table by the specified key. As the hash table is
4898 collision resistant it also makes it possible to have several
4899 duplicate keys in the hash table. This function may be used to
4900 find all of the keys from the hash.
4902 Added user_context arguments to the SilcHashFunction,
4903 SilcHashCompare and SilcHashDestructor to deliver user specified
4906 Added new fuctions silc_hash_table_find[_all]_ext to do
4907 extended lookup with specified hash and compare functions and
4908 specified user contexts.
4910 Added new function silc_hash_table_add_ext to add the key
4911 with specified hash function and user context.
4913 Added new function silc_hash_table_foreach to traverse all
4914 entrys in the hash table. Added SilcHashForeach callback
4917 Added new function silc_hash_table_del_by_context to delete
4918 the entry only if the context associated with the key matches.
4920 Affected files are lib/silcutil/silchashtable.[ch].
4922 * Removed silc_hash_[server/client/channel]_id and added just
4923 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4924 silc_hash_id_compare to compare two ID's using as the hash table
4925 comparison function. Added also silc_hash_data to hash
4926 binary data and silc_hash_data_compare to compare it.
4928 * Removed silc_idlist_find_client_by_hash as it is not needed
4929 anymore. Affected file silcd/idlist.[ch].
4931 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4932 to use internally the SilcHashTable. The new ID Cache is a lot
4933 faster than the old one. Some of the ID Cache interface was also
4934 rewritten and obsolete and stupid functions were removed.
4936 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4938 * Added entry_count field to the SilcHashTable to keep the number
4939 of the entries in the table. Implemented the function
4940 silc_hash_table_rehash. Added new function
4941 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4943 Fixed a minor bug in silc_hash_table_free.
4945 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4946 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4947 into the lib/silcutil/silcutil.[ch].
4949 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4951 * Implemented a collision resistant hash table into the
4952 lib/silcutil/silchashtable[ch]. See the header and the source
4953 for the SilcHashTable API.
4955 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4957 * Merged dotconf version 1.0.2 into lib/dotconf.
4959 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4961 * Do not compile anything in lib/silcsim/* if the SIM support
4962 is not enabled. The tree should now compile without problems
4965 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4967 * Compiled the SILC under cygwin. Compiled and tested briefly
4968 without problems. More tests needed. The SIMs didn't compile
4971 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4973 * Fixed possible crash in silc_get_username in the
4974 lib/silcutil/silcutil.c.
4976 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4978 * Fixed a va_arg in silc/client_ops.c.
4980 * Oops, RC5 routines were named AES and caused some problems
4981 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4983 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4985 * Added new SilcIDIP structure into the lib/silccore/id.h and
4986 replaced the old `ip' fields from all SILC ID's to that type.
4987 This is a step towards IPv6 support.
4989 The silc_id_get_len takes now the ID as an extra argument.
4990 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4991 both IPv4 and IPv6 based ID's.
4993 The affected files are lib/silccore/id.[ch] and other files
4994 around the tree using these routines.
4996 * Removed the ID length arguments in server from various
4997 silc_server_send_notify_* routines -> they are not needed
5000 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5002 * Fixed memory leak in silc_encode_pem_file in the file
5003 lib/silcutil/silcutil.c.
5005 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5007 * Check minor version as well in the SKE. Affected files are
5008 silcd/protocol.c and lib/silcclient/protocol.c.
5010 * Added --identifier option to the server so that an identifier
5011 can be when creating the public key for the server. Affected
5012 file is silcd/silcd.c.
5014 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
5015 lib/silccrypt/silcpkcs.c.
5017 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5019 * Register default ciphers and stuff when using -C option with
5020 the server. Affected file sildc/silcd.c.
5022 * Put back the servers public key filename format, it is better
5023 than the new one. For now, the client keys are saved with the
5024 new filename format. The affected file silc/client_ops.c.
5026 * Implemented the Cipher API for the rest of the ciphers that
5027 did not implement it or implemented it the wrong way.
5029 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5031 * Register default ciphers and stuff when using the -S option
5032 in the client. Affected file silc/silc.c. Same also when
5033 creating new key pair with -C option.
5035 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5037 * Fixed the silc_verify_public_key client operation function to
5038 save the public keys differently. The fingerprint is now
5039 used as filename and not the hostname. This way also the
5040 client keys are saved uniquely and not with hostnames. The
5041 affected file is silc/client_ops.c.
5043 * Trimmed the silc_hash_fingerprint function to remove extra
5044 whitespaces from the end of the fingerprint. The affected
5045 file is lib/silccrypt/silchash.c.
5049 * Added silc_cipher_register_default function to register all
5050 default ciphers. It can be used when configuration files
5051 does not exist and the application does not want any specific
5052 ciphers in any specific order.
5054 The SilcDList is now used as silc_cipher_list dynamically
5055 allocated cipher list. Removed the static list all together
5056 and now all ciphers must be allocated to the dynamic list.
5057 The silc_cipher_alloc routine was changed to check only the
5060 All silc_cipher_* routines that used to return int returns
5063 The affected files lib/silccrypt/silccrypt.[ch].
5065 * The same thing was done to silc_hash_* as for silc_cipher_*
5066 routines. Affected files lib/silccrypt/silchash.[ch].
5068 * The same thing was done to silc_pkcs_* as for silc_cipher_*
5069 routines. Affected files lib/silccrypt/silcpkcs.[ch].
5070 Added also silc_pkcs_[un]register[_default] functions.
5071 Removed the data_context from the PKCS API.
5073 * Added silc_hmac_register_default function to register default
5074 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
5075 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
5076 to unregister all hmacs at once.
5078 * Register the default ciphers, hash functions, PKCSs and HMACs
5079 if client's configuration file does not exist. The affected
5082 * The client did not load the hash functions from the SIM
5083 modules at all. Added support for this. Affected file is
5084 silc/clientconfig.c.
5086 * When decoding public key with silc_pkcs_public_key_decode, check
5087 the supported algorithm only if PKCS are registered. Affected
5088 file lib/silccrypt/silcpkcs.c. The same was done with the
5089 silc_pkcs_private_key_decode.
5091 * Fixed the SILC List routines to keep the list always in order.
5092 It used to change the list's order when traversing the list but
5093 not it preserves the order. Affected file lib/trq/silclist.h.
5095 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5097 * Added the client library to use the SilcSocketConnection's
5098 reference counter (by silc_socket_dup) to prevent the bug that
5099 the socket object may be freed underneath async operation.
5101 * The name resolv library checking fixes in the configure.in.pre.
5104 * Created new version of the protocol drafts for future
5105 development. The -03 drafts are the ones that will be changed
5106 in the trunk now and the -02 will remain as they are.
5108 * Send list of CUMODE notifys to the router when announcing
5109 the channel users to the router. Affected file silcd/server.c.
5110 If the router receiving channel founder CUMODE for a channel
5111 that already has channel founder it will send CUMODE notify
5112 to the sender to remove the channel founder rights from the
5113 announced client. Affected file silcd/packet_receive.c.
5115 * The CUMODE notify may now use Server ID as well as the entity
5116 who changes the mode. Updated protocool specs.
5118 * Updated INSTALL and README files.
5120 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5122 * New web pages in the http://silc.pspt.fi. The pages was
5127 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5129 * Implemented the [DenyConnectin] config section in the server.
5130 Added silc_server_config_denied_conn to check whether incoming
5131 connection is denied. Affected file silcd/serverconfig.[ch].
5133 * Do not check the ports when checking the incoming configuration
5134 data if the port is 0, meaning any. Affected file is
5135 silcd/serverconfig.c.
5137 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5139 * Fixed buffer overflow in silc_string_compare in the file
5140 lib/silcutil/silcutil.c.
5142 * Fixed double free in silc_server_command_leave in the file
5145 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5147 * Fixed the version checking in the server. Affected file is
5150 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5152 * Fixed the configuration data fetching when accepting new
5153 connections in the server. Affected file silcd/server.c.
5155 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5157 * Added `sender_entry' argument to the function
5158 silc_server_packet_relay_to_channel so that we can check
5159 whether some destination actually belongs to the same route
5160 the sender belongs (ie, we must not resend the packet to the
5161 sender). Affected file silcd/packet_send.[ch].
5163 * Added `servername' field to the SilcClientEntry in the server
5164 to hold the name of the server where client is from. Affected
5165 file is silcd/idlist.h.
5167 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5169 * Moved the channel message encrypting in the router betwen
5170 router connections from silc_server_channel_message to the
5171 silc_server_packet_relay_to_channel since we want to check
5172 whether we have anybody channel before encrypting anything.
5173 Affected files silcd/packet_[receive/send].c.
5175 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5177 * Fixed the [AdminConnection] server config section to support
5178 multiple entries. Affected file silcd/serverconfig.c.
5180 * Added support into the server to check the validity of the
5181 incoming connection before executing any KE or authentication
5184 * The connection configuration is now saved to the KE and
5185 connection auth protocol contexts and not fetched anymore in
5186 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
5188 * The local hosts listenning address and port is also resolved
5189 now when starting the server. We want to have the socket object
5190 to include the real address and port for the listener. Added
5191 new function silc_net_check_local_by_sock into the files
5192 lib/silcutil/silcnet.[ch].
5194 * Fixed a broadcast bug in server -> do not broadcast if we
5197 * Fixed a routing bug. Do not route broadcast packets ever.
5198 Broadcast packets must be processed always and not routed since
5199 they may be destined to some other host than yourself and thus
5200 would get routed without no good reason. Affected file is
5203 * Added function silc_server_config_is_primary_route to check
5204 whether primary router connection has been configured (a router
5205 configuration that we are initiating). If there is not, we
5206 will assume that there is only two routers in the SILC network
5207 and we will use the incoming router connection as our primary
5208 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
5210 * Changed the order of the broadcasting. Broadcast _after_ the
5211 packet has been processed not before. Affected file is
5214 * Fixed a [ClientConnection] parsing bug. The port was never
5215 parsed correctly thus resulting to port 0. Affected file
5216 silcd/serverconfig.c.
5218 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
5219 argument and did not set the broadcast packet flag. Affected
5220 file silcd/packet_send.c. Fixed same bug in the function
5221 silc_server_send_notify as well.
5223 * If we receive NEW_ID packet for our own ID in the server, ignore
5226 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5230 * Removed the nickname from the Private Message Payload.
5231 Updated the code and the protocol specs.
5233 * Updated protocol specs for submitting to the IETF.
5235 * Tweaked the Random Number Generator a bit. Affected file
5236 lib/silccrypt/silcrng.c. Exported a new function
5237 silc_rng_[global]_add_noise which can be used to add more
5240 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5242 * Do not parse packets with different timeout when protocol
5243 is active -> may cause problem with rekey. Affected file
5246 * When server receives signoff notify it must not create
5247 new channel key if the client is on any channels since the
5248 sender of the signoff notify will create it.
5250 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5252 * Added printing of error messages during SKE protocol from the
5253 failure packet sent by server during SKE. Affected file
5256 * Removed the client's failure_callback handling with timeout
5257 and handle it immediately when received.
5259 * The SKE library returned wrong type in SUCCESS and FAILURE
5260 packets. They must be 32 bit MSB not 16 bit MSB.
5262 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5264 * Ok, rewrote the logic of the re-key and now it seems to work.
5265 I tested it on high traffic with frequent re-keys without
5266 problems. Added hmac_receive (and renamed hmac to hmac_send)
5267 in SilcClientConnection in lib/silcclient/client.h and
5268 in SilcIDListData in silcd/idlist.h. Also, removed the
5269 SilcPacketParserContext's cipher and hmac fields as they are
5270 not needed anymore and actually caused some problems when
5271 the ciphers and hmac's changed underneath the packet parser.
5273 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5275 * If re-key protocol is active then process the incoming packets
5276 synchronously since we must assure that icoming packets encrypted
5277 with the old key is processed before the new keys is set to
5278 use. This is true other packets than for REKEY packets.
5279 Affected file silcd/server.c. The same was done to client library
5280 as well, affected file lib/silcclient/client.c.
5282 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5284 * Fixed bug in client and server to accept the force send if
5285 the packet is send from silc_[server/client]_packet_process
5286 function. Otherwise the packets are never delivered, oops.
5288 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5290 * Disable force sending of packets when REKEY protocol is active.
5291 We must assure that no packet is sent directly when rekey is
5292 performed. All packets must be sent through packet queue.
5293 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
5294 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
5295 function is silc_[server/client]_packet_send_real to check
5298 * Replaced the SIM paths from example config files to
5299 /usr/local/modules. Also, make install creates now
5300 /usr/local/silc/logs directory to hold all the SILC server
5303 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5305 * Made the configure.in.pre work on Solaris. Patch by salo.
5307 * Made all ciphers compatible with non-x86 machines. Defined
5308 CBC mode macros into lib/silccrypt/ciphers_def.h.
5310 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5312 * Fixed the make install.
5314 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5316 * When MAC computation fails the silc_packet_decrypt returned 0
5317 even though it was supposed to return -1. Fixed this. The
5318 affected file is lib/silccore/silcpacket.c.
5320 * Do not replace the config files in /etc/silc (in make install)
5321 if they already exist. Affected file ./Makefile.am.
5323 * Do not send re-key packets immediately but through packet queue.
5324 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
5326 * Changed silc_net_check_host_by_sock to return FALSE if the
5327 IP/DNS could not be resolved. Though, it returns the IP address
5328 now even if it could not resolve it (but returns also FALSE).
5329 Affected file lib/silcutil/silcnet.[ch].
5331 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5333 * Added silc_pkcs_decode_identifier to decode the public key's
5334 identifier. Affected file lib/silccrypt/silpkcs.[ch].
5335 Added also silc_pkcs_free_identifier. Added also new context
5336 SilcPublicKeyIdentifier.
5338 * Added -S option to the silc client. It is used to dump the
5339 contents of the specified public key file.
5341 * Changed the PKCS api to return the public key length when
5342 setting the public key.
5344 * Fixed a fatal bug in the public and private key file loading.
5345 Affected file lib/silccrypt/silcpkcs.c.
5347 * Execute the packet parsing for client with zero (0) timeout
5348 if the protocol is active. Affected file silcd/server.c.
5350 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5352 * Made the key generation options to the silcd program. Added
5353 -C option, equivalent to client's option.
5355 * Added new [ServerKeys] config section to the server. It
5356 configures the server's public and private key.
5358 * Defined generic Public Key Payload into the protocol
5359 specification to send specific type of public keys and
5362 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
5363 public key or certificate.
5365 * Implemented the GETKEY command to the server and to the
5366 client library and on user interface.
5368 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5370 * Made preliminary `make install' work.
5372 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5374 * Added SilcServerRekey context into silcd/idlist.h.
5376 * Added the PFS support as defined in the specification to the
5377 SKE protocol. Affected files lib/silcske/*.c.
5379 * Added `ske_group' field to the SilcServerRekey context to hold
5380 the number of the SKE group that is used with PFS in re-key.
5381 Affected file silcd/idlist.h.
5383 * Added PFS re-key support to the server. Affected file is
5386 * Added silc_protocol_cancel to cancel execution of the next
5387 state of the protocol. Affected file is
5388 lib/silccore/silcprotocol.[ch].
5390 * Added the re-key support with and without PFS to the client
5391 library. Re-key is performed once in an hour, by default.
5393 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
5394 Added silc_client_rekey_callback and silc_client_rekey_final.
5395 Affected files are lib/silcclient/protocol.[ch] and
5396 lib/silcclient/client.[ch].
5398 * Removed the `hmac_key' and `hmac_key_len' fields from the
5399 SilcClientConnection structure; not needed. Affected file is
5400 lib/silcclient/client.h.
5404 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5406 * Do not ask whether user wants to use the negotiated private key
5407 for private messages, just use it. Affected file is
5408 silc/local_command.c.
5410 * Added `send_enc_key' and `enc_key_len' fields to the
5411 SilcIDListData structure since they are needed in the re-key
5412 phase. Affected file is silcd/idlist.[ch].
5414 * Implemented the simple re-key protocol into the server.
5415 Affected files silcd/server.c and silcd/protocol.[ch]. The
5416 re-key will be performed once in an hour, by default.
5418 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
5419 Added silc_server_rekey, silc_server_rekey_callback and
5420 silc_server_rekey_final.
5422 * Removed Tunneled flag from the protocol. Updated the code
5423 and the specifications.
5425 * Adde `pfs' field to the SilcIDListData to indicate whether
5426 the PFS is to be performed in the re-key. Affected file is
5429 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5431 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
5432 int64 of at least the xintXX size. If void * is less that 4
5433 bytes uint32 * will be used. Defined bool as boolean.
5435 * Changed _ALL_ unsigned long and unsigned int to uint32,
5436 unsgined short to uint16 in the source tree.
5438 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
5439 not handle clients that has entry->data.registered == FALSE.
5440 They are not in the network anymore. Affected file is
5443 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5445 * Implemented the sending of the SERVER_SIGNOFF notify in the
5446 server. Affected file is silcd/server.c.
5448 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
5449 Added also silc_notify_payload_encode_args into the
5450 lib/silccore/silcnotify.[ch].
5452 * Implemented ther SERVER_SIGNOFF notify handling in the server.
5453 Affected file silcd/packet_receive.c.
5455 * Implemented the SERVER_SIGNOFF notify handling in the client
5456 library. Affected file lib/silcclient/client_notify.c. Also,
5457 implemnted the printing of the SERVER_SIGNOFF info to the
5458 application. Affected file silc/client_ops.c.
5460 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
5461 if the deleting was successful. Affected file silcd/idlist.[ch].
5463 * Added support for public key authentication in the connection
5464 authentication protocol in the client library. Affected file
5465 lib/silcclient/protocol.c.
5467 * Changed the server's silc_idlist_get_clients_by_* interface
5468 to support already allocated array so that new entries may be
5469 added to pre-allocated array. Affected file silcd/idlist.[ch].
5470 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
5471 and command replies.
5473 * All command reply functions in the server now calls the
5474 pending command callback even if error occured. This way the
5475 error will be delivered to the client as well. Affected files
5476 silcd/command.c and silcd/command_reply.c.
5478 * Fixed INFO command to return local server's info if no server
5479 was provided. Affected file lib/silcclient/command.c.
5481 * Removed RESTART command for good. Updated the code and the
5484 * Rewrote parts of the task system. It is a bit simpler now.
5485 Removed unsued task priorities. The affected files are
5486 lib/silcutil/silctask.[ch].
5488 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5490 * Moved the USERS printing from the library to the application.
5491 Affected files lib/silcclient/command.c and silc/client_ops.c.
5493 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5497 * Added channel key re-key support. The re-key is perfomed
5498 only by the router and is done once in an hour. Added `rekey'
5499 field to the SilcChannelEntry in the server. Affected files
5500 silcd/server.c and silcd/idlist.h.
5502 * Added silc_task_unregister_by_context into the file
5503 lib/silcutil/silctask.[ch].
5505 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5507 * Added SILC_UMODE_GONE mode to indicate when the client is not
5508 present in the SILC network. Added also support to the local
5509 command AWAY that will set this mode. Added support of showing
5510 "xxx is gone" in WHOIS command. The USERS command shows the
5511 gone status as well.
5513 * Fixed setting server and router operator privileges in the
5514 server's UMODE command. Affected file silcd/command.c.
5516 * Merged the SKE KE1 and KE2 payloads into one payload. The
5517 new KE payload is equivalent to the old KE2 payload.
5519 Cleaned up the SKE Start Payload parsing. It now uses the
5520 simple buffer unformatting to do the parsing. A lot faster
5523 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
5524 to the SKE that is used to indicate whether both of the SKE
5525 parties should perform authentication. By default only the
5526 responder performs authentication. By setting this flag also
5527 the initiator must do authentication. By default it is unset
5528 since in normal SKE case, client to server connection, only
5529 the responder should do authentication. When doing SKE between
5530 two clients both should perform authentication. Updated the
5531 code and the protocol specs.
5533 * A little fix to IDENTIFY command in the server. Search the
5534 client first by hash not nickname. Affected file is
5537 * Fixed the silc_client_close_connection to support closing
5538 the client to client connections wihtout deleting too much
5539 data. Affected file lib/silcclient/client.c.
5541 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
5542 are received if protocol used to be active but is not anymore
5543 the application would crash due to NULL pointer dereference.
5544 Affected files silcd/server.c and lib/silcclient/client.c.
5546 * Added `hash' field to the SilcClientConnection to include
5547 the hash function negotiated in the SKE protocol.
5549 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
5550 to set the channel founder authentication data. A client can
5551 claim the founder rights later by providing the authentication
5552 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
5553 This way the channel founder can regain the channel founder
5554 privileges even it is left the channel. This works only on
5555 local server and the client must be connected to the same
5556 server to be able to regain the founder rights. Updated the
5557 protocol specs accordingly.
5559 Added support to the CMODE command in the client to set the
5560 founder auth data. Read the README to see how to set it.
5562 Added support to the CUMODE command to claim the founder
5563 rights. Read the README to see how to do it.
5565 Added support for the founder authentication to the Channel
5566 Entry in the server. Affected file silcd/idlist.h.
5568 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
5569 server's CMODE command. Affected file silcd/command.c.
5571 * Added the following new functions into lib/silccore/silcauth.[ch]:
5572 silc_auth_get_method and silc_auth_get_data.
5574 * The server now saves the remote hosts public key to the
5575 SilcIDListData pointer. Affected file silcd/protocol.c.
5577 * The normal server now does not remove the channel entry from
5578 the cache if the founder authentication data is set. It used
5579 to remove it if the founder was the last one on the channel on
5580 the server and left the channel. The auth data is saved and
5581 if the channel is re-joined later the old entry is used with
5582 the old auth data. Affected files silcd/command_reply.c and
5585 * Removed the `pkcs' field from the SilcIDListData structure
5586 in the server; it is not used. Affected file silcd/idlist.h.
5588 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5590 * Fixed packet processing on slow links. Partial packets were
5591 never re-processed because the incoming data buffer was cleared
5592 by the application. Application must not directly clear the
5593 sock->inbuf, the packet processing routines handle it. Fixed
5594 this in client library and in server.
5596 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5598 * Fixed the WHOIS and IDENTIFY send reply function to really
5599 check whether to send list or just one entry. Affected file
5602 * Cleaned up the LEAVE command's channel key distribution. The
5603 affected file silcd/command.c.
5605 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
5606 can enforce the channel mode as well. In that case the ID
5607 includes the ID of the server. The code now enforces the
5608 mode change if the router have different mode than the server.
5610 * The notify client operation with CMODE_CHANGE notify can now
5611 return NULL client_entry pointer if the CMODE was not changed
5612 by client. Application must check for this.
5614 * Added <Server ID> argument to INFO command to support server
5615 info fetching by Server ID.
5617 * Added silc_server_announce_get_channel_users to get assembled
5618 packets of channel users of the specified channel. Affected
5619 file silcd/server.[ch].
5621 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
5622 was freed underneath the ID Cache.
5624 * Re-announce clients when the server received CHANNEL_CHANGE
5625 notify from the router. Affected file silcd/packet_send.c.
5627 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5629 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
5630 crashed since it did not handle the fact that there is no cipher
5631 called "3" and didn't check the error condition. Now fixed.
5633 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
5634 flag. It can be used to send message requests.
5636 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5638 * Implemented the RESTART command in the client.
5640 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
5641 notice type messages. Added notice printing to the user
5644 * The channel keys are not re-generated if the channel's mode
5645 is PRIVKEY, ie private key on the channel exists. Affected
5646 files silcd/server.c and silcd/command.c.
5648 * Fixed a little bug in channel message delivery when channel
5649 private keys are set in the server. Affected file is
5650 silcd/packet_send.c.
5652 * Changed the setting on channel->on_channel = TRUE from the
5653 silc_client_save_channel_key to the JOIN command reply. The
5654 key payload is not received if the private channel key is set.
5655 Affected file lib/silcclient/command_reply.c and the
5656 lib/silcclient/client_channel.c.
5658 * When the CMODE_CHANGE notify is sent and the channel private
5659 key mode is removed the channel key must be re-generated in
5660 other cells as well. Added this support for the router in the
5661 silcd/packet_receive.c.
5663 * Added new local command NOTICE to send notice message on
5664 channel. Affected file silc/local_command.[ch].
5666 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5668 * Added new local command ME to the client. It is used to send
5669 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
5670 some action. Affected file silc/local_command.[ch].
5672 * Changed channel_message and private_message client operations
5673 to deliver the message flags to the application. Added also
5674 the `flags' arguments to the silc_client_send_channel_message
5675 and silc_client_send_private_message functions. Affected file
5678 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5680 * Redefined the Private Message Payload to support private message
5681 keys and to support the new private message flags. Updated
5682 the protocol specs. Flags makes it possible to have for example
5683 CTCP style messages.
5685 * Added new type SilcPrivateMessagePayload and defined an API
5686 for it in the lib/silcclient/silcprivate.[ch].
5688 * Tested private message private keys successfully. Tested the
5689 private message key set, unset and list commands with the new
5692 * Redefined the Channel Message Payload to include the channel
5693 message flags (equal with private message flags) to support
5694 for example CTCP style messages.
5696 * Defined some of the message (for channel and private message)
5697 flags. Updated the protocol specs and added the flags to the
5698 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5700 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5702 * Added SilcKeyAgreementStatus type to the key agreement routines
5703 to indicate the current status and error if one occured.
5704 The status types are defined in the lib/silcclient/silcapi.h.
5706 * Added new local command KEY that is used to set and unset private
5707 keys for channels, set and unset private keys for private messages
5708 with remote clients and to send key agreement requests and
5709 negotiate the key agreement protocol with remote client. The
5710 key agreement is supported only to negotiate private message keys,
5711 it currently cannot be used to negotiate private keys for channels,
5712 as it is not convenient for that purpose.
5714 * Fixed a minor pending callback setting bug in the function
5715 silc_client_get_client_by_id_resolve, now the function works.
5716 Affected file lib/silcclient/idlist.c.
5718 * Added function silc_net_get_local_port to get local bound
5719 port by socket. Added to lib/silcutil/silcnet.[ch].
5721 * Added `sockets' and `sockets_count' fields to the SilcClient
5722 object. They hold the sockets of the listenning sockets in
5723 the client. Listenning sockets may be for example the key
5724 agreement server. Affected file lib/silcclient/client.[ch].
5725 Added functions the silc_client_add_socket and the
5726 silc_client_del_socket. They are exported to the application
5729 * Added ~./silc/clientkeys to support other client's public keys.
5731 * Renamed verify_server_key client operation to verify_public_key
5732 and added one argument to indicate the type of the connection
5733 (server, client etc.).
5735 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5737 * Added silc_server_connection_auth_request to handle the
5738 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5739 silcd/packet_receive.[ch].
5741 * Added silc_server_send_connection_auth_request into the
5742 silcd/packet_send.c to send the connection auth request packet.
5744 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5747 * Fixed the public key authentication in responder side in the
5748 server. The `auth_data' pointer includes the SilcPublicKey
5749 not the path to the public key. Affected file silcd/protocol.c.
5751 * Implemented the public key authentication in the initiator side
5752 in the server. Affected file silcd/protocol.c.
5754 * Removed the [RedirectClient] config section from the server
5755 configuration. Is not needed and I don't want to implement it.
5757 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5759 * Cleaned up the CMODE command in the server. It now works
5760 correctly and supports all the modes defined in the protocol.
5761 Affected file is silcd/command.c.
5763 * Added `hmac_name' field to the SilcChannelEntry in the server
5764 to hold the default HMAC of the channel. It can be set when
5765 creating the channel (with JOIN command). Affected files
5768 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5769 type to indicate the change of the current cipher and hmac
5770 on the channel. Client can safely ignore the <cipher> argument
5771 (if it chooses to do so) since the CHANNEL_KEY packet will
5772 force the channel key change anyway. The <hmac> argument is
5773 important since the client is responsible of setting the new
5774 HMAC and the hmac key into use.
5776 * Fixed the CMODE command in the client library as well.
5778 * Tested CMODE command in router environment successfully.
5780 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5782 * Show the version of the remote client (or server) when connecting
5783 to the server. It is logged to the log file. Affected file
5784 is silcd/protocol.c.
5786 * Fixed the KILLED notify handling in the client library. The
5787 client must be removed from all channels when receiving the
5790 Also, do not remove the client entry when giving the KILL
5791 command but when the KILLED notify is received.
5793 * Removed silc_idlist_find_client_by_nickname from the server.
5794 Not needed anymore. Affected files silcd/idlist.[ch].
5796 * Implemented the CHANNEL_CHANGE notify type handling to the
5797 server. Affected file silcd/server.c.
5801 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5803 * Added silc_server_send_notify_invite to send the INVITE
5804 notify between routers.
5806 * Implemented the INVITE command correctly to the server.
5808 * Implemented the INVITE notify type handling in the server.
5810 * Implemented the INVITE command to the client library and on the
5813 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5815 * Added function silc_server_get_client_resolve to find the
5816 client entry by ID from all ID lists and then resolve it
5817 (using WHOIS) if it cannot be found. Affected file is
5820 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5822 * Implemented the BAN command to the client library.
5824 * The JOIN command in the server now checks the invite list
5827 * Changed the silc_command_reply_payload_encode_va and the
5828 silc_command_payload_encode_va to support that if argument is
5829 NULL it ignores and checks the next argument. Affected file
5830 lib/silccore/silccommand.c.
5832 * Added silc_server_send_notify_ban to send the BAN notify
5833 type between routers.
5835 * Chaned the silc_notify_payload_encode to support that if
5836 argument is NULL it ignores and checks the next argument.
5837 Affected file lib/silccore/silcnotify.c.
5839 * Tested ban lists in router environment successfully.
5841 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5843 * Implemented BAN command to the server, in silcd/command.[ch].
5845 * Removed the BAN and INVITE_LIST modes from the CMODE command
5848 * Added function silc_string_match to regex match two strings.
5849 Affected files lib/silcutil/silcutil.[ch].
5851 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5853 * Redefined parts of the SilcChannelEntry in the server to support
5854 the new ban and invite lists.
5856 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5858 * Redefined the INVITE command. The same command can be used to
5859 invite individuals to the channel but also to manage the invite
5860 list of the channel (to add to and remove from the invite list).
5861 Updated the protocol specs.
5863 * Added new command SILC_COMMAND_BAN that can be used to manage
5864 the ban list of the channel. Updated the protocol specs.
5866 * Removed the channel modes: the SILC_CMODE_BAN and the
5867 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5868 in the CMODE command. The equivalent features are now available
5869 using INVITE and BAN commands. Updated the protocol specs.
5871 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5872 in the network about change in the current ban list. The notify
5873 type is not used by the client.
5875 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5876 support the invite lists.
5878 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5880 * Added new function silc_string_regexify that converts string
5881 including wildcard characters into regex string that can
5882 be used by the GNU regex library. Added into the file
5883 lib/silcutil/silcutil.[ch].
5885 Added silc_string_regex_combine to combine to regex strings
5886 into one so that they can be used as one regex string by
5887 the GNU regex library. Added into the file
5888 lib/silcutil/silcutil.[ch].
5890 Added silc_string_regex_match to match two strings. It returns
5891 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5893 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5895 * Imported GNU regex to the soruce tree into lib/contrib.
5896 Fixed some compiler warning from the regex.c.
5898 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5900 * Fixed MOTD command in the server to work in router environment.
5902 * Fixed the MOTD command in the client library to support
5903 the server argument in the command.
5905 * Added `nickname_len' argument to the silc_idlist_add_client
5906 in the server, as the `nickname' argument may be binary data
5909 * Added silc_idlist_get_channels to return all channels from
5912 * Implemented LIST command to the server. Affected file is
5915 * Implemented the LIST command to the client library and on the
5918 * Added [<user count>] argument to the LIST command reply.
5919 With private channels the user count is not shown.
5921 * Updated TODO and README.
5923 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5925 * The client entry's data.registered must be TRUE even with
5926 global client entry on global client list. The data.registered
5927 is used to check whether the client is anymore in the network,
5928 for example with WHOWAS command so it must be valid.
5930 * Fixed the WHOWAS command in the server. It now actually works
5931 in router environment. Added function into silcd/command_reply.c
5932 silc_server_command_reply_whowas_save.
5934 * Added silc_idlist_purge function to the silcd/idlist.c
5935 to periodically purge the ID Cache.
5937 * Fixed INFO command in the server. It works now in router
5938 environment. Added <server name> argument to the INFO command
5939 reply. Updated the protocol specs.
5941 * Fixed minor bug in silc_idcache_purge to not purge if the
5942 expire value is zero.
5944 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5945 they were buggy because of the WHOWAS information.
5947 * Fixed local command MSG to handle the async resolving of
5948 the remote client properly. It used to fail the first MSG.
5949 Affected file silc/local_command.c.
5951 * Added `data_len' field to SilcIDCache context.
5953 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5955 * Update TODO. Todo in commands in the server.
5957 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5959 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5960 used by routers as broadcast packet to inform other routers
5961 about the changed user mode.
5963 Implemented the notify handling in the server. Affected file is
5964 silcd/packet_receive.c. Added the function
5965 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5967 * Added new generic Channel Payload and deprecated the New Channel
5968 Payload. The New Channel Payload is now the generic Channel
5971 * Added new argument `mode' to the silc_server_send_new_channel
5972 as it is required in the Channel Payload now.
5974 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5975 and created a new and real SilChannelPayload to represent the
5976 new generic Channel Payload. Implemented the encode/decode
5977 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5979 * Added silc_server_get_client_channel_list to return the list
5980 of channels the client has joined for WHOIS command reply.
5981 Affected file silcd/server.[ch].
5983 * Implemented the channel list sending in the WHOIS command reply
5984 in server and in the client.
5986 Implemented the channel list displaying on the user interface
5987 as well. Affected file silc/client_ops.c.
5989 * Added silc_channel_payload_parse_list to parse list of Channel
5990 Payloads. It returns SilcDList list of SilcChannelPayloads.
5991 Client for example can use this function to parse the list of
5992 channels it receives in the WHOIS command reply. The caller
5993 must free the list by calling silc_channel_payload_list_free.
5994 Affected files lib/silccore/silcchannel.[ch].
5996 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5998 * Added one new argument <user mode> to the WHOIS command reply
5999 to return the mode of the user in SILC. Updated the protocol
6002 Implemented it to the server and client.
6004 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6006 * Fixed the mode printing on the user interface on joining.
6007 Affected file silc/client_ops.c.
6009 * Implemented the UMODE command and user modes in general to the
6010 client library and to the user interface.
6012 * Implemented the UMODE command to the server.
6014 * The server now sends UNKNOWN_COMMAND error status if client sends
6015 unknown command. Affected file silcd/command.c.
6017 * All server commands now handle the command identifier the right
6018 way when sending the command reply to the client. The client can
6019 use to identify the command replies with the identifier.
6021 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6023 * Added silc_server_get_client_route to resolve the route to
6024 the client indicated by the client ID. Affected file is
6027 * Added silc_server_relay_packet as general function to relay
6028 packet to arbitrary destination. This deprecates functions
6029 like _send_private_message_key, _relay_notify etc. Affected
6030 file is silcd/packet_send.[ch].
6032 Removed silc_server_send_key_agreement,
6033 silc_server_send_private_message_key and
6034 silc_server_packet_relay_notify functions from the file
6035 silcd/packet_send.[ch].
6039 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
6040 server. Affected file silcd/packet_receive.[ch].
6042 * Implemented the KILL command to the client. Implemented the
6043 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
6044 Affected files lib/silcclient/command[_reply].c and
6045 lib/silcclient/client_notify.c. Implemented the KILL notify
6046 printing in the user inteface.
6048 * Fixed a lot silc_parse_nick memory leaks from the client
6049 library in the file lib/silcclient/command.c.
6051 * Changed the silc_server_send_notify_on_channels's `sender'
6052 argument from SilcSocketConnection to SilcClientEntry to
6053 check the sender as entry and not as connection object and not
6054 to send to the client provided as argument. The affected file
6055 is silcd/packet_send.[ch].
6057 * The notify packets that are destined directly to the client used
6058 to not to be processed by the server. Now changed that and the
6059 server processes all notify packets. After relaying the packet
6060 to the client the notify packet is processed in the server.
6062 * The silc_server_free_client_data now checks whether there is
6063 pending outgoing traffic for the client and purges the data to
6064 the network before removing the client entry.
6066 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6068 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
6069 an client is killed from the SILC Network. Updated the protocol
6072 Added new function silc_server_send_notify_killed to the
6073 silcd/packet_send.[ch].
6075 * Added function silc_server_packet_relay_notify to relay notify
6076 packets that are destined directly to a client. In this case
6077 the server does not process the notify packets but merely relays
6078 it to the client. Affected file silcd/packet_send.[ch].
6080 Added also silc_server_packet_process_relay_notify to check
6081 whereto relay the notify. Affected file is
6082 silcd/packet_receive.[ch].
6084 * Implemented the KILL command to the server.
6088 * Added the backup schema desgined last fall to the protocol
6089 specs for everyone to see. The specification is in the
6090 *-spec-xx.txt draft and the packet type definitions for the
6091 backup routers is in *-pp-xx.txt draft. Thusly, added also
6092 new packet type SILC_PACKET_CELL_ROUTERS.
6094 * A big security problem in the implementation discovered. The
6095 signoff of an client did not cause new channel key generation
6096 which it of course should've done. The channel keys must be
6097 always re-generated when client leaves (or signoffs) the channel.
6098 The silc_server_remove_from_channels funtion now handles
6099 the channel key re-generation.
6101 * Added `sender' argument to the silc_server_send_notify_on_channels
6102 to not to send the client provided as argument. Affected file
6103 silcd/packet_send.[ch].
6105 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6107 * Implemented OPER and SILCOPER commands into the server and
6110 * Added silc_auth_verify and silc_auth_verify_data to verify
6111 the authentication directly from the authentication payload.
6112 It supports verifying both passphrase and public key based
6113 authentication. Affected file lib/silccore/silcauth.[ch].
6115 * Added `hash' field to the SilcIDListData structure. It is the
6116 hash negotiated in the SKE protocol. Affected file is
6119 * Slight redesigning of the SilcAuthPayload handling routines.
6120 Do not send SilcPKCS but SilcPublicKey as argument.
6122 * Implemented the public key authentication support to the
6123 serverconfig. The public key is loaded from the provided path
6124 and saved as authentication data to void * pointer. Thus,
6125 changed the unsigned char *auth_data to void *auth_data;
6127 * Fixed SHUTDOWN command to send the reply before the server
6128 is shutdown. :) Affected file silcd/command.c.
6130 * Fixed fatal bug in CONNECT command. The hostname was invalid
6131 memory and server crashed. Affected file silcd/command.c.
6133 * Fixed fatal bug in CLOSE command. The server_entry became
6134 invalid but was referenced later in the command. Affected file
6137 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6139 * Fixed fatal bug in failure packet handling. Server ignored
6140 the failure and thus crashed when it came.
6144 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6146 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
6147 that the command may be executed only once in (about) 2 seconds.
6148 The old SILC_CF_LAG flag is same but allows command bursts up
6149 to five before limiting.
6151 Added the support for CF_LAG and CF_LAG_STRICT flags to the
6152 server code. Various commands now includes the CF_LAG_STRICT
6153 flag to disallow any kind of miss-use of the command.
6155 * Fixed the silc_buffer_unformat to not to allocate any data
6156 if the length of the data is zero. It used to allocate the
6157 length + 1. Affected file lib/silcutil/silcbuffmt.c.
6159 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6161 * Changed the format of AdminConnection configuration section
6162 in the server. Added username of the admin to the format.
6163 Affected files silcd/serverconfig.[ch].
6165 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
6166 to return admin configuration data by host, username and/or
6169 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6171 * Implemented WHOWAS command to the server. Added the functions:
6173 silc_server_command_whowas_parse,
6174 silc_server_command_whowas_send_reply,
6175 silc_server_command_whowas_from_client and
6176 silc_server_command_whowas_from_server
6178 * Added <Client ID> argument to the WHOWAS command reply. Updated
6179 the protocol specs accordingly.
6181 * Implemented WHOWAS command and command_reply to the client
6184 Implemented the WHOWAS printing on the user interface.
6186 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6188 * Added new argument to the WHOWAS command reply, the real name.
6189 It is an optional argument. Updated the protocol specs.
6191 * Added SilcIDCacheDestructor callback that is registered when
6192 the SilcIDCache is allocated. The callback is called when
6193 an cache entry in the ID Cache expires, or is purged from the
6194 cache. Added into lib/silccore/idcache.[ch].
6196 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
6197 to destruct the client entries when the cache entry expires.
6198 Other ID Cache's in server and in the client library ignores
6201 * If the ID Cache entry's `expire' field is zero then the entry
6202 never expires. Added boolean `expire' argument to the
6203 silc_idcache_add function in the lib/silccore/idcache.[ch].
6204 If it is TRUE the default expiry value is used.
6206 * Added silc_server_free_client_data_timeout that is registered
6207 when client disconnects. By default for 5 minutes we preserve
6208 the client entry for history - for WHOWAS command.
6210 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6212 * Added support to the server to enforce that commands are not
6213 executed more than once in 2 seconds. If server receives
6214 commands from client more frequently, timeout is registered
6215 to process the commands. Affected file silcd/command.c.
6216 Added new function silc_server_command_process_timeout.
6218 * Changed NICK_NOTIFY handling in client library to check that
6219 if the client's nickname was changed, so there is no need to
6220 resolve anything from the server.
6222 * Removed error printing from the WHOIS and IDENTIFY commands.
6223 If error occurs then it is ignored silently in the client library.
6224 The application, however, may map the received error to
6225 human readable error string. The application currently maps
6226 the NO_SUCH_NICKNAME error to string.
6228 * Made the command status message public to the application. Moved
6229 them from lib/silcclient/command_reply.c to
6230 lib/silcclient/command_reply.h. The application can map the
6231 received command status to the string with the
6232 silc_client_command_status_message function.
6234 * Added check to the server to check that client's ID is same
6235 as the Source ID in the packet the client sent. They must
6238 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6240 * Added dist-bzip hook to the Makefile.am to make bzip2
6241 compressed distributions.
6243 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6245 * Server now enforces the maximum length for the nickname and
6246 the channel as protocol specification dictates. 128 bytes for
6247 nickname and 256 bytes for channel name.
6249 * Moved the WHOIS printing to the application. The client libary
6250 does not print out the WHOIS information anymore, the application
6251 must do it. Renamed silc_client_command_reply_whois_print to
6252 the silc_client_command_reply_whois_save.
6254 The client's idle time is also sent to the application now, and
6255 the idle is shown on screen.
6257 * Added silc_client_command_reply_identify_save to save the
6258 received IDENTIFY entries.
6260 * Do not check for channel private keys in message sending and
6261 reception if the channel does not have the PRIVKEY mode set.
6262 Affected file lib/silclient/client_channel.c.
6264 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6266 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
6267 just surfaced after chaning the JOIN procedure.
6269 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6271 * Added silc_client_get_clients_by_list to get client entries
6272 from Client ID list, that is returned for example by JOIN
6273 and USERS command replies. The application should use this
6274 function for example when JOIN command reply is received to
6275 resolve the clients already on the channel (library does not
6276 do that anymore as USERS command reply is not used in the JOIN
6277 procedure anymore). Affected files lib/silcclient/silcapi.h and
6278 lib/silcclient/idlist.c.
6280 * JOIN command reply and USERS command reply returns now SilcBuffer
6281 pointers instead of unsigned char pointers when returning
6282 the client list and mode list.
6284 * Added <Client ID> argument to the JOIN command reply, mainly
6285 for the server to identify for which client the command was
6286 originally sent. Updated protocol specs accordingly.
6288 * Added SilcDlist private_key pointer to the SilcChannelEntry
6289 in the client to support the channel private keys. Affected
6290 file is lib/silcclient/idlist.h.
6292 * Added SilcChannelPrivateKey argument to the function
6293 silc_client_send_channel_message so that application can choose
6294 to use specific private ke if it wants to. If it is not provided,
6295 the normal channel key is used, unless private keys are set.
6296 In this case the first (key that was added first) is used
6297 as the encryption key.
6299 * Implemented the support for channel private key handling.
6300 Implemented the following functions:
6302 silc_client_add_channel_private_key,
6303 silc_client_del_channel_private_keys,
6304 silc_client_del_channel_private_key,
6305 silc_client_list_channel_private_keys and
6306 silc_client_free_channel_private_keys
6308 Affected file lib/silcclient/client_channel.c.
6310 * Added the support for the private keys in the channel message
6311 sending and encryption and in the message reception and
6312 decryption. Affected funtions are
6313 silc_client_send_channel_message and silc_client_channel_message.
6315 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6317 * Added SKE's key verify callback to the client library's
6318 KE protocol context. Affected files lib/silcclient/protocol.[ch].
6320 * Removed the statement that server (or router) must send USERS
6321 command reply when joining to the channel so that the client
6322 knows who are on the channel. Instead, the client list and
6323 client's mode list is now sent in the JOIN command reply to the
6324 client who joined channel. This is better solution.
6326 * Added function silc_server_get_users_on_channel and function
6327 silc_server_save_users_on_channel to the silcd/server.[ch].
6329 * Removed function silc_server_command_send_users from the
6332 * Do not show topic on the client library anymore. The topic is
6333 sent in the command reply notify to the application and the
6334 application must show the topic now.
6336 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6338 * Added client searching by nickname hash into the IDENTIFY and
6339 WHOIS commands in the server as they were clearly missing from
6340 them. Affected file is silcd/command.c.
6342 * Fixed a bug in private message receiving in the client library.
6343 The remote ID was freed and it wasn't supposed, now it is
6346 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6348 * Minor fix to the channel payload; allocate the data area, as it
6349 needs to be of specific length.
6351 * If the key agreement port is zero then the operating
6352 system will define the bound port. Affected files are
6353 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
6355 * Added new function silc_channel_payload_decrypt into the file
6356 lib/silccore/silcchannel.[ch].
6358 * Moved the channel message etc, check from silc_packet_decrypt
6359 to applications. The library calls now a generic
6360 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
6361 when the packet is either normal or special. This was done to
6362 allow more wide range of checking that was not allowed when
6363 the code was in library. Now applications can do virtually any
6364 checks to the packet and return to the library the decision how
6365 the packet should be processed. Affected files are
6366 lib/silccore/silcpacket.[ch].
6368 Added silc_server_packet_decrypt_check to the server and
6369 silc_client_packet_decrypt_check to the client library.
6371 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
6372 to send with specified source and destination information.
6374 * Channel message delivery between routers was broken after the
6375 channel key distribution was fixed earlier. The channel key
6376 was used be to distributed to other routers as well which is not
6377 allowed by the protocol. Now this is fixed and channel keys
6378 really are cell specific and the channel message delivery between
6379 routers comply with the protocol specification.
6381 * Fixed various commands in server to check also the global list
6382 for the channel entry and not just the local list. The affected
6383 file silcd/command.c.
6385 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6387 * Added assert()s to buffer formatting and unformatting routines
6388 to assert (if --enable-debug) when error occurs. Affected
6389 file: lib/silcutil/silcbuffmt.c.
6391 * Changed to auto-reconnect to check whether the remote host is
6392 router and register the re-connect timeout if it is. It used
6393 to check that whether we are normal server, but router must do
6394 auto-reconnect with another router as well. Affected file
6397 * Removed the [<key len>] option from CMODE command as the cipher
6398 name decides the key length, nowadays. See the defined ciphers
6399 from the protocol specification.
6401 * Added [<hmac>] option to the CMODE command to define the HMAC
6402 for the channel. Added SILC_CMODE_HMAC channel mode.
6404 * Added [<hmac>] option for the JOIN command so that user can
6405 select which HMAC is used to compute the MACs of the channel
6408 * Added Hmac field to the Channel Message Payload. The integrity
6409 of plaintext channel messages are now protected by computing
6410 MAC of the message and attaching the MAC to the payload. The
6411 MAC is encrypted. Now, it is clear that this causes some
6412 overhead to the size of the packet but rationale for this is that
6413 now the receiver can verify whether the channel message decrypted
6414 correctly and also when private keys are set for the channel the
6415 receiver can decrypt the packet with several keys and check from
6416 the MAC which key decrypted the message correctly.
6418 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
6419 lib/silccrypt/silccipher.[ch].
6421 * Added silc_hash_len to return the digest length into the
6422 lib/silcrypt/silchash.[ch].
6424 * Rewrote parts of Silc Channel Payload interface in the
6425 lib/silccore/silcchannel.[ch]. The encode function now also
6426 encrypts the packet and parse function decrypts it.
6428 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6430 * Fixed a minor formatting bug in the SKE's key material processing.
6431 It actually might have processed the keys wrong way resulting
6434 * Redefined the mandatory HMAC algorithms and added new algorithms.
6435 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
6436 and hmac-md5 truncated to 96 bits. The mandatory is now
6437 hmac-sha1-96. Rest are optional (including the one that used
6438 to be mandatory). Rationale for this is that the truncated HMAC
6439 length is sufficient from security point of view and can actually
6440 make the attack against the HMAC harder. Also, the truncated
6441 HMAC causes less overhead to the packets. See the RFC2104 for
6444 * Added new [hmac] configuration section. The SKE used to use
6445 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
6446 is of course wrong. The official names that must be proposed in
6447 the SKE are the ones defined in the protocol specification
6448 (hmac-sha1-96 for example). The user can configure any hmac
6449 using any hash function configured in the [hash] section. At
6450 least, the mandatory must be configured.
6452 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
6454 * Added HMAC list to the SKE proposal list. It has now both
6455 hash algorithm list and HMAC list. This makes the protocol
6456 incompatible with previous versions. The SKE now seems to work
6457 the way it is supposed to work, for the first time actually.
6459 * Defined plain Hash algorithms to the protocol specification.
6462 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6464 * Implemented support for key agreement packets into the server.
6465 Added functions silc_server_key_agreement and
6466 silc_server_send_key_agreement. Other than these functions,
6467 server has nothing to do with this packet.
6469 * Added support for private message key packets into the server.
6470 Added functions silc_server_private_message_key and
6471 silc_server_send_private_message_key.
6475 * Changed the silc_[client|server]_protocol_ke_set_keys to be
6476 called in the protocol's final callback instead in the END
6477 protocol state. This makes a little more sense and in the same
6478 time in client we can use the same protocol routines for normal
6479 key exchange and to key agreement packet handling as well.
6481 * Added to both client's and server's KE protocol context the
6482 SilcSKEKeyMaterial pointer to save the key material. We will
6483 bring the key material to the protocol's final callback by doing
6484 this. The final callback must free the key material.
6486 * Added SKE's packet_send callback into client's KE protocol
6487 context so that the caller can choose what packet sending function
6488 is used. This way we can use different packet sending when
6489 doing normal SKE when doing key agreement packet handling (in
6490 the key agreement packet handling we do not want to encrypt
6493 * Implemented the responder side of the key agreement routines
6494 in the client. The client can now bind to specified port and
6495 accept incoming key negotiation. The key material is passed
6496 to the application after the protocol is over.
6498 * Implemented the processing of incoming Key Agreement packet
6499 in the client. Added function silc_client_key_agreement to
6502 * Implemented the intiator side of the key agreement routines
6503 in the client. The client can now initiate key agreement with
6504 another remote client. The key material is passed to the
6505 application after the protocol is over.
6507 * Created client_keyagr.c to include all the key agreement
6510 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
6511 SILC_TASK_CALLBACK except that it is not static.
6513 * Created client_notify.c and moved the Notify packet handling
6514 from the client.[ch] into that file.
6516 * Created client_prvmsg.c and moved all private message and
6517 private message key routines from the client.[ch] into that file.
6519 * Create client_channel.c and moved all channel message and
6520 channel private key routines from the client.[ch] into that file.
6522 * Changed silc_client_get_client_by_id_resolve to resolve with
6523 WHOIS command instead of IDENTIFY command, in the file
6524 lib/silclient/idlist.c.
6526 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6528 * Implemented the SKE's responder side to the Client library.
6530 * When FAILURE is received to the protocol do not trust it
6531 blindly. Register a timeout to wait whether the remote closes
6532 the connection as it should do it, only after that process the
6533 actual failure. This was changed to both client and server.
6535 * Added client_internal.h to include some of the structures
6536 there instead of client.h in lib/silcclient/.
6538 * Added function silc_task_unregister_by_callback to unregister
6539 timeouts by the callback function.
6541 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6543 * Some "Incomplete WHOIS info" errors has been appearing on the
6544 log files. Took away the entry->userinfo check from WHOIS
6545 reply sending. The entry->userinfo is now " " if client did not
6546 provide one. I thought this was fixed earlier but something
6547 is wrong still. Let's see if the error still appears.
6549 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6551 * Fixed a minor bug in the login when the channel key is
6552 re-generated in the server. It used to generate the key in
6553 wrong order and thus caused problems in the channel traffic.
6555 * Fixed a minor bug in channel key distsribution after
6556 KICK command. The key was not sent to the router even though
6559 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6561 * Added silc_ske_process_key_material_data as generic routine
6562 to process any key material as the SILC protocol dictates. The
6563 function is used by the actual SKE library but can be used by
6564 applications as well. This relates to the private message keys
6565 and the channel private keys since they must be processed the
6566 same way the normal SILC session keys. The protocol dictates
6567 this. Affected files: lib/silcske/silcske.[ch].
6569 Added also silc_ske_free_key_material to free the
6570 SilcSKEKeyMaterial structure.
6572 * Defined silc_cipher_set_key function to set the key for
6573 cipher without using the object's method function. The affected
6574 files: lib/silccrypt/silccipher.[ch].
6576 * Implemented silc silc_client_add_private_message_key,
6577 silc_client_add_private_message_key_ske,
6578 silc_client_del_private_message_key,
6579 silc_client_list_private_message_keys and
6580 silc_client_free_private_message_keys functions in the
6583 Added functions silc_client_send_private_message_key to send
6584 the Private Message Key payload and silc_client_private_message_key
6585 to handle incoming Private Message Key payload.
6587 * Added Cipher field to the Private Message Key payload to set
6588 the cipher to be used. If ignored, the default cipher defined
6589 in the SILC protocol (aes-256-cbc) is used.
6591 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6593 * Removed lib/silcclient/ops.h file.
6595 Redefined parts of the SILC Client Library API. Created new
6596 file silcapi.h that deprecates the ops.h file and defines the
6597 published Client Library API. Defined also private message key
6598 API and channel private key API into the file.
6600 This is the file that the application must include from the
6601 SILC Client Library. Other files need not be included by
6602 the application anymore.
6604 * Added new key_agreement client operation callback and also
6605 defined the Key Agreement library API for the application.
6607 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6609 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
6610 is used by clients to request key negotiation between another
6611 client in the SILC network. If the negotiation is started it
6612 is performed using the SKE protocol. The result of the
6613 negotiation, the secret key material, can be used for example
6614 as private message key.
6616 Implemented the Key Agreement payload into the files
6617 lib/silccore/silauth.[ch].
6619 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6621 * Redefined ciphers for the SILC protocol. Added some new ciphers
6622 and defined the key lengths for the algorithms. Changed the
6623 code accordingly. The default key length is now 256 bits.
6625 * Fixed SKE key distribution function silc_ske_process_key_material
6626 when the key length is more than 128 bits. The default key
6627 length in SILC is now 256 bits.
6629 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
6630 to indicate unsupported algorithm.
6632 * Renamed rijndael.c to aes.c and all functions as well.
6634 * Fixed a long standing channel key setting bug in client library.
6635 Weird that it has never surfaced before.
6637 * Fixed bug in channel deletion. If the entire channel is removed
6638 then it must also delete the references of the channel entry
6639 from the client's channel list as the client's channel entry and
6640 the channel's client entry share same memory.
6642 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6644 * Implemented CONNECT and SHUTDOWN commands in the client.
6646 * Implemented CLOSE command to the client.
6648 * Added the function silc_idlist_find_server_by_name into the
6649 files silcd/idlist.[ch].
6651 Added the function silc_idlist_find_server_by_conn into the
6652 files silcd/idlist.[ch].
6654 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6656 * DIE command was renamed to SHUTDOWN. Updated the both code
6659 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
6660 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
6662 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
6665 * Added function silc_server_create_connection function to create
6666 connection to remote router. My server implementation actually
6667 does not allow router to connect to normal server (it expects
6668 that normal server always initiates the connection to the router)
6669 so the CONNECT command is only good for connecting to another
6672 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6674 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
6675 or some other client was kicked from the channel.
6677 Implemented the handling of the notify type to both client
6680 Implemented silc_server_send_notify_kicked to send the KICKED
6681 notify. It is used to send it to the server's primary router.
6683 * Implemented the KICK command into server and client.
6685 * Added `query' argument to the silc_idlist_get_client function
6686 to indicate whether to query the client from server or not if
6689 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
6690 to indicate that the client is not channel founder.
6694 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6696 * Removed the rng context from SilcPacketContext structure and
6697 changed that the packet routine uses the Global RNG API.
6699 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6701 * Added support for quit message that client can "leave" on the
6702 channel when it quits the SILC. It is ditributed inside the
6703 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6705 Added silc_server_free_client_data that will take the
6706 signoff message as argument.
6708 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6710 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6712 * Updated parts of the protocol specification to keep it up
6715 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6717 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6718 payloads in one packet.
6720 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6721 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6722 use now the new List flag.
6724 * Also deprecated the following packet types: REPLACE_ID,
6725 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6727 * Added list support for Notify packet in server.
6729 * Added silc_server_send_notify_channel_change to send the
6730 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6731 the silc_server_send_replace_id.
6733 * Added silc_server_send_notify_nick_change to send the
6734 NICK_CHANGE notify type. Deprecates the function
6735 silc_server_send_replace_id.
6737 * Added silc_server_send_notify_join to send the JOIN notify type.
6738 Deprecates the function silc_server_send_new_channel_user.
6740 * Added silc_server_send_notify_leave to send LEAVE notify type.
6741 Deprecates the function silc_server_send_remove_channel_user.
6743 * Added silc_server_send_notify_cmode and
6744 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6745 types. Deprecates the silc_server_send_set_mode function.
6747 * Added SERVER_SIGNOFF notify type to indicate that server has
6748 quit. This means that all clients on the channel from that
6749 server will drop. This can be also used when netsplit happens.
6751 Deprecated REMOVE_ID packet type since it is not needed anymore
6754 Added silc_server_send_notify_server_signoff to send the
6755 SERVER_SIGNOFF notify type. Deprecates the function
6756 silc_server_send_remove_id.
6758 Added also silc_server_send_notify_signoff to send the
6759 SIGNOFF notify type.
6761 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6762 SILC protocol from this day on. Changed the protocol
6763 specification as well.
6765 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6766 notify type. It is used between routers to notify about
6767 topic changes on a channel.
6769 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6772 * Partly updated the protocol specification to comply with the
6773 changes now made. It is still though a bit outdated.
6775 * The JOIN notify type now takes one extra argument <Channel ID>.
6776 The packet used to be destined to the channel but now the
6777 JOIN type may be sent as list thus it is impossible to
6778 destine it to any specific channel. By adding this argument
6779 it is again possible.
6781 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6783 * Added CREDITS file. The CHANGES and CREDITS file will appear
6784 in the distribution as well.
6786 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6788 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6789 types in the server's silcd/packet_receive.c.
6791 * Implemented CMODE and CUMODE to work in router environment.
6793 * Fixed minor encoding and decoding buglet from the
6794 lib/silccore/silcmode.c.
6796 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6799 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6801 * Changed all SilcConfigServer* and silc_config_server* to
6802 SilcServerConfig* and silc_server_config*, respectively.
6805 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6807 * Associated the ID (client or server ID) to the Authentication
6808 Payload to avoid any possibility of forging. Updated the
6809 protocol specification and the code accordingly.
6811 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6813 * The RSA key length is now save to the RsaKey context in the
6814 key generation process in lib/silccrypt/rsa.c. The key length
6815 is now used to figure out the maximum size of the block allowed
6816 to be encrypted/signed.
6818 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6819 is equivalent to the silc_mp_mp2bin but does not allocate any
6822 * Changed silc_mp_mp2bin API to take length argument. If it is
6823 non-zero then the buffer is allocated that large. If zero, then
6824 the size is approximated using silc_mp_sizeinbase, which however
6827 * Created Global RNG API which is global RNG that application can
6828 initialize. After initializing, any routine anywhere in the
6829 code (including library) can use RNG without allocating a new
6830 RNG object. This was done to allow this sort of use of the
6831 RNG in code that has no chance to allocate RNG object. All
6832 applications currently allocate this and many routines in the
6833 library use this. Affected file lib/silccrypt/silcrng.[ch].
6835 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6836 it to use the Global RNG API.
6838 * Defined Authentication Payload into protocol specification that
6839 is used during SILC session to authenticate entities. It is
6840 used for example by client to authenticate itself to the server
6841 to obtain server operator privileges.
6843 Implemented this payload into the lib/silccore/silcauth.[ch].
6844 Implemented also routines for public key based authentication
6845 as the new protocol specification dictates.
6847 Moved definitions of different authentication methods from
6848 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6850 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6851 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6852 silc_pkcs_verify_with_hash functions into the file
6853 lib/silccrypt/silcpkcs.[ch].
6855 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6857 * The client entry's userinfo pointer must be always valid.
6858 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6859 will fail since it requires the userinfo. Now, the userinfo
6860 is allocated as "" if actual userinfo does not exist. Actually,
6861 it must exist and it is totally Ok to drop client connections
6862 that does not announce the userinfo. However, we will make
6863 this workaround for now.
6865 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6866 to return the remote port by socket.
6868 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6870 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6871 SILC_SERVER_PENDING_EXEC and added an new macro
6872 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6873 data or when error occurs while processing the pending command.
6875 Added new argument `destructor' into silc_server_command_pending
6876 and to the SilcServerCommandPending object. This destructor is
6877 now called after calling the pending callback or if error occurs
6878 immediately. If error occurs the actual pending callback won't
6879 be called at all - only the destructor. The destructor may be
6880 NULL if destructor is not needed.
6882 All this applies for client library code as well. Similar
6883 changes were made there as well for the pending commands.
6885 In the client, the application must now allocate the
6886 SilcClientCommandContext with the silc_client_command_alloc
6889 * Added reference counter to the SilcServerCommandContext. Added
6890 function silc_server_command_alloc and silc_server_command_dup
6893 Same type of functions added to the client library for the same
6896 * Removed the cmd_ident from IDListData away since it is now
6897 global for all connections. It is the command identifier used
6898 in command sending and with pending commands. The affected file
6901 * Added reference counter to the SilcSocketConnection objecet to
6902 indicate the usage count of the object. The object won't be
6903 freed untill the reference counter hits zero. Currently only
6904 server uses this, and client ignores it. The client must be
6905 set to use this too later. The affected files are
6906 lib/silccore/silcsockconn.[ch]. Added also the function
6907 silc_socket_dup to increase the reference counter.
6909 This was mainly added because it is possible that the socket
6910 is removed underneath of pending command or other async
6911 operation. Now it won't be free'd and proper DISCONNECTING
6912 flags, etc. can be set to avoid sending data to connection that
6913 is not valid anymore.
6915 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6916 the connection. After that it sets SILC_SET_DISCONNECTED.
6917 It is, however, possible that the socket data is not still freed.
6918 The silc_server_packet_process now checks that data is not
6919 read or written to connection that is DISCONNECTED. The socket
6920 get's freed when the reference counter hits zero.
6922 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6924 * Changed the client operation API: channel_message operation's
6925 `sender' is now the client entry of the sender, not the nickname
6926 and the `channel' is the channel entry, not the channel name.
6928 In the private_message operation the `sender' is now also the
6929 client entry of the sender not the nickname.
6931 Affected file is lib/silcclient/ops.h and all applications
6932 using the client operations.
6934 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6936 * Moved the calling of ops->connect() from connect_to_server_final
6937 into receive_new_id functin since that is the point when the
6938 client is actually allowed to send traffic to network. The
6939 affected file is lib/silcclient/client.c.
6941 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6943 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6944 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6945 (if needs broadcasting) instead of broadcasting the packets one
6946 by one which would make a burst in the network traffic.
6948 * Added `broadcast' argument to the functions in silcd/server.[ch]
6949 silc_server_create_new_channel[_with_id] to indicate whether
6950 to send New Channel packet to primary router.
6952 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6954 * Added new function into the silcd/server.[ch] files:
6955 silc_server_create_new_channel_with_id to create new channel with
6956 already existing Channel ID.
6958 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6959 lib/silccore/silcpacket.h. This packet is used t send list of
6960 Set Mode payloads inside one packet. Server uses this to set
6961 the modes for the channels and clients on those channels, that it
6962 announced to the router when it connected to it. The protocol
6963 specification has been updated accordingly.
6965 * The silc_server_new_channel did not handle the packet coming
6966 from normal server as it normally does not send that. However,
6967 when it announces its channels it does send it. Implemented
6968 the support for that.
6970 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6971 into the file lib/silccore/id.h.
6973 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6975 * Fixed memory leaks in the functions silc_idlist_del_client,
6976 silc_idlist_del_channel and silc_idlist_del_server in the file
6977 silcd/idlist.c. All of those leaked like a sieve.
6979 * Fixed some small memory leaks in the client's function
6980 silc_client_notify_by_server.
6982 * Added functions into silcd/server.c: silc_server_announce_clients,
6983 silc_server_announce_channels and silc_server_announce_server.
6984 These functions are used by normal and router server to announce
6985 to its primary router about clients, channels and servers (when
6986 router) that we own. This is done after we've connected to the
6989 These functions effectively implements the following packet types:
6990 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6991 and SILC_PACKET_NEW_ID_LIST.
6993 * Added new functions into the silcd/packet_receive.[ch]:
6994 silc_server_new_id_list, silc_server_new_channel_list and
6995 silc_server_new_channel_user_list to handle the incoming
6996 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6998 * Added support of changing Channel ID in the function
6999 silc_server_replace_id. If the server that announces a channel
7000 to the router already exists in the router (with same name but
7001 with different Channel ID), router is responsible to send
7002 Replace ID packet to the server and force the server to change
7003 the Channel ID to the one router has.
7005 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
7006 client that the Channel ID has been changed by the router. The
7007 normal server sends this to the client. Client must start using
7008 the new Channel ID as the channel's ID.
7010 Implemented handling of this new type into lib/silcclient/client.c
7011 into the function silc_client_notify_by_server.
7013 * Added new function silc_idlist_replace_channel_id into the files
7014 silcd/idlist.[ch] to replace the Channel ID.
7016 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7018 * Call silc_server_command_identify_check always when processing
7019 the IDENTIFY command in silcd/command.c
7021 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7023 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
7024 send keepalive packets. The packet can be sent by clients,
7025 servers and routers.
7027 Added function silc_socket_set_heartbeat into the file
7028 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
7029 If not set, the heartbeat is not performed. The actual
7030 heartbeat is implemented in the low level socket connection
7031 library. However, application is responsible of actually
7034 Added silc_server_send_heartbeat to send the actual heartbeat
7035 packet into silcd/packet_send.[ch]. Server now performs
7036 keepalive with all connections.
7038 * Added silc_task_get_first function into lib/silcutil/silctask.c
7039 to return the timeout task with shortest timeout. There was a bug
7040 in task unregistration that caused problems. TODO has been
7041 updated to include that task system must be rewritten.
7043 * The client library will now resolve the client information when
7044 receiving JOIN notify from server for client that we know but
7045 have incomplete information.
7047 * Rewrote parts of silc_server_remove_from_channels and
7048 silc_server_remove_from_one_channel as they did not remove the
7049 channel in some circumstances even though they should've.
7051 * Encryption problem encountered in server:
7053 The LEAVE command used to send the Channel Key packet to the
7054 router immediately after generating it. However, the code
7055 had earlier sent Remove Channel user packet but not immediately,
7056 ie. it was put to queue. The order of packets in the router
7057 was that Channel Key packet was first and Remove Channel User
7058 packet was second, even though they were encrypted in the
7059 reverse order. For this reason, MAC check failed. Now, this
7060 is fixed by not sending the Channel Key packet immediately but
7061 putting it to queue. However, this is more fundamental problem:
7062 packets that are in queue should actually not be encrypted
7063 because packets that are sent immediately gets encrypted
7064 actually with wrong IV (and thus MAC check fails). So, packets
7065 that are in queue should be encrypted when they are sent to
7066 the wire and not when they put to the queue.
7068 However, the problem is that the current system has not been
7069 designed to work that way. Instead, the packet is encrypted
7070 as soon as possible and left to the queue. The queue is then
7071 just purged into wire. There won't be any fixes for this
7072 any time soon. So, the current semantic for packet sending
7075 o If you send packet to remote host and do not force the send
7076 (the packet will be in queue) then all subsequent packets to the
7077 same remote host must also be put to the queue. Only after the
7078 queue has been purged is it safe again to force the packet
7081 o If you send all packets immediately then it safe to send
7082 any of subsequent packets through the queue, however, after
7083 the first packet is put to queue then any subsequent packets
7084 must also be put to the queue.
7086 Follow these rules and everything works fine.
7088 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7090 * Added new function silc_server_remove_clients_by_server to
7091 remove all client entries from ID list when the server connection
7092 is lost. In this case it is also important to invalidate all
7093 client entires as they hold the invalid server entry. This
7094 fixes fatal bug when server has lost connection and will reconnect
7097 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7099 * Made some sanity checks to silc_server_daemonise like to check
7100 whether the requested user and group actually exists.
7102 * Added sanity check to SKE's silc_ske_responder_finish to check
7103 that the public and private key actually is valid.
7105 * Invalidate the client's nickname when receiving Replace ID
7106 packet and the Client ID is being replaced. This means that the
7107 server will query the nickname if someone needs it (client)
7110 * Sort the ID Cache in client library when the ID Cache data
7111 has changed (needs sorting).
7113 * Do not allow for SILC client to create several connections to
7114 several servers. The client does not support windows right now
7115 and generating multiple connections causes weird behaviour.
7117 Irssi-silc client does support windows and can handle several
7118 connections without problems, see: www.irssi.org and SILC plugin.
7120 * Fixed some places where client was added to the IDList. The
7121 rule of thumb is following (in order to get everything right):
7122 If the client is directly connected local client then the
7123 `connection' argument must be set and `router' argument must be
7124 NULL to silc_idlist_add_client function. If the client is not
7125 directly connected client then the `router' argument must
7126 bet set and the `connection' argument must be NULL to the
7127 silc_idlist_add_client function.
7129 * The funtion silc_server_packet_send_local_channel actually did
7130 not check whether the client was locally connected or not. It
7131 does that now. Fixed a bug related to LEAVE command.
7133 * Fixed Remove Channel User payload parsing bug in server's
7134 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
7136 * The server's silc_server_save_channel_key now checks also the
7137 global ID list for the channel as it might not be in the local
7138 list. Fixed a bug related to LEAVE command.
7140 * Is this the end of the [<unknown>] buglet that has been lurking
7141 around for a long time? A little for loop fix in server's
7142 silc_server_command_whois_parse that is used by both IDENTIFY
7143 and WHOIS command. At least, this was a clear bug and a cause
7144 of one type of [<unknown>] buglet.
7146 * WHOIS and IDENTIFY commands call the function
7147 silc_server_command_[whois/identify]_check function even if
7148 we are not router server.
7150 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7152 * Added --with-gmp configuration option. If set the GMP
7153 is always compiled in the SILC source tree. If not set then
7154 it is checked whether the system has the GMP3 installed. If
7155 it has then the GMP won't be compiled (the system's headers
7156 and library is used), if it doesn't have it then the GMP is
7157 compiled in the SILC source tree.
7159 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7161 * Changed RSA private exponent generation to what PKCS #1
7162 suggests. We try to find the smallest possible d by doing
7163 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
7164 not security fix but optimization.
7166 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7168 * Added new config entry [Identity] to fork the server and run
7169 it as specific user and group. A patch from Bostik.
7171 * Imported Dotconf configuration library into lib/dotconf.
7172 This will be used to create the SILC configuration files later.
7173 It will appear in the distsribution after this commit.
7175 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7177 * A big code auditing weekend happening. Auditing code for
7178 obvious mistakes, bugs and errors. Also, removing any code
7181 Removed files for being obsolete:
7183 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
7184 inline in the file lib/silcutil/silcbuffer.h)
7186 o lib/silcutil/silcbufutil.c (the header has inline versions)
7188 Changed code to fix possible error conditions:
7190 o The buffer formatting routines now check that the destination
7191 buffer really has enough space to add the data. This applies for
7192 both buffer formatting and unformatting
7193 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
7194 unformatting was changed to accomodate following rules:
7195 XXX_*STRING_ALLOC will allocate space for the data into the pointer
7196 sent to the function while XXX_*STRING will not allocate or copy
7197 the data into the buffer. Instead it sets the pointer from the
7198 buffer into the pointer sent as argument (XXX_*STRING used to
7199 require that the pointer must be allocated already). This change
7200 makes this whole thing a bit more consistent and more optimized
7201 (note that the data returned in the unformatting with XXX_*STRING
7202 must not be freed now). The routines return now -1 on error.
7204 o Tried to find all code that use buffer_format and buffer_unformat
7205 and added return value checking to prevent formatting and
7206 especially unformatting errors and possible subsequent fatal
7209 o Changed ske->x and ske->KEY to mallocated pointers in
7210 lib/silcske/silcske.h. Fixed possible data and memory leak.
7212 o Added return value checking to all *_parse* functions. Fixed
7213 many memory leaks as well.
7215 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
7216 so that buffer overflows would not happen. All code now also
7217 checks the return value as it can fail.
7219 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7221 * Added reconnection support to server if the normal server looses
7222 its connection to the router (for example if router is rebooted).
7223 The server performs normal reconnection strategy implemented
7224 to the server. Affected file silcd/server.c.
7226 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7228 * Added new packet type SILC_PACKET_SET_MODE that is used to
7229 distribute the information about changed modes (for clients,
7230 channels and clients channel modes) to all routers in the
7231 network. Updated the protocol specification accordingly.
7233 Added functions into silcd/packet_send.c and
7234 silcd/packet_receive.c: silc_server_send_set_mode,
7235 silc_server_set_mode.
7237 Added new files silcmode.[ch] into lib/silccore that implements
7238 the encoding and decoding of Set Mode Payload. Added new type
7239 SilcSetModePayload. Moved the definitions of different modes
7240 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
7242 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7244 * Oops, a little mistake in server's connection authentication
7245 protocol. The protocol is not ended with FAILURE but with
7246 SUCCESS if the authentication is Ok. :) Affected file is
7249 * Implemented NICK_CHANGE notify handling in server in the file
7250 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
7251 the local clients on the channel. After the changing nickname
7252 in router environment snhould work and the [<unknown>] nickname
7253 should appear no more.
7255 The silc_server_replace_id function that receives the Replace ID
7256 payload now sends the NICK_CHANGE notify type also in the file
7257 silcd/packet_receive.c
7259 * Changed WHOIS and IDENTIFY command to support the maximum amount
7260 of arguments defined in protocol specs (3328 arguments). This
7261 fixed a bug that caused problems when there were more than three
7264 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7266 * Added extra parameter, command identifier, to the
7267 silc_client_send_command so that explicit command identifier
7270 Changed that ID list routines uses specific command identifier
7271 when sending WHOIS/IDENTIFY requests to the server so that they
7272 can be identified when the reply comes back.
7274 Affected files lib/silcclient/command.[ch],
7275 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
7277 * Added `sender' argument to silc_server_packet_send_to_channel
7278 to indicaet the sender who originally sent the packet to us
7279 that we are now re-sending. Ignored if NULL. Affected file
7280 silcd/packet_send.[ch].
7282 * Added some server statistics support in silcd/server_internal.h
7283 SilcServerStatistics structure and around the server code. Also
7284 send some nice statistics information when client is connecting
7287 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7289 * Fixed channel ID decoding in server's JOIN command reply in
7290 silcd/command_reply.c
7292 * Fixed braodcasting of replace ID payload to not to send it if
7293 we are standalone server in silcd/packet_receive.c.
7295 * Fixed all channel message sending routines to not to send
7296 packets to clients that has router set, since they are routed
7297 separately in the same function earlier. Affects file
7298 silcd/packet_send.c and all channel packet sending functions.
7300 * In USERS reply, res_argv[i] are not allocated, the table
7301 is allocated. Thus changed that free the table, not its
7304 * In server's whois_check and identify_check if the client is
7305 locally connected do not send any WHOIS commands - they are not
7308 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7310 * Fixed some minor bugs in client when sending WHOIS command. The
7311 arguments was in wrong order.
7313 * Removed statis function add_to_channel from server in
7314 silcd/command.c that was previously used with the joining but
7317 * Tested USERS command in router environment successfully with two
7318 routers, two servers and two clients.
7320 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7322 * Reorganized the USERS command and command reply in client library
7323 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
7324 When the command is given by user we register a pending command
7325 callback that will reprocess the command after the reply has been
7326 received from the server. When reprocessing the packet we then
7327 display the information. Thus, the USERS information is displayed
7328 now in the command callback instead of in the command reply
7329 callback. The processing of the command is same as previously
7330 when server has sent the command reply in the JOINing process.
7332 * Added to USERS command in silcd/command_reply.c to join the client,
7333 we didn't use to know about, to the channel after we've created
7334 a client entry for it. Also, for clienet we did know already still
7335 check whether it is on the channel or not and add it if not.
7337 * Removed silc_server_command_join_notify as the function and its
7340 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7342 * Changed the client's pending command handling to the same as the
7343 server's pending command handling. It is also now possible to
7344 execute command reply functions from other command reply
7345 function as the function callbacks for commands and command
7346 replies are one and same. The pending commands are not static
7347 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
7348 in client connection context. Thus, pending commands are server
7349 connection specific as it is convenient.
7351 Changed the function silc_client_command_pending and
7352 silc_client_command_pending_del and added new function
7353 silc_client_command_pending_check. Removed the
7354 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
7357 * Added cmd_ident, current command identifier, to the client
7358 connection context in lib/silcclient/client.h to keep track on
7359 command identifiers used in command sending. Client's command reply
7360 function handling now supports the mandatory command identifiers.
7362 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
7363 funtions in client to fully support pending command callbacks.
7365 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
7366 as one of the arguments to the application in the command reply
7369 * NOTE: The FORWARDED flag is depracated. It used to be depracated
7370 before first releasing SILC but came back. Now it is removed again
7371 and should come back nomore. The FORWARDED flag was used only
7372 by the JOINing procedure by forwarding the command packet to router.
7373 Now, the JOINing procedure has been changed to more generic (due
7374 to various router environment issues) and FORWARDED is not needed
7375 anymore for anything. The protocol specification is yet to be
7378 Now, removed silc_server_packet_forward from server and the flag
7379 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
7381 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7383 * Renamed NAMES command to USERS command. The NAMES was named that
7384 due to historical reasons. Now it is renamed. Also, rewrote
7385 parts of the USERS command. The nickname list is not sent anymore
7386 by the server. Only Client ID and mode lists are sent in the USERS
7387 command. Changed this also to the protocol specification.
7389 The client now resolves the names and stuff after it receives
7390 the USERS list from the server when joining to the channel.
7392 * WHOIS and IDENTIFY commands has been changed to support multiple
7393 Client ID's per command. One can now search for multiple users
7394 in the network by sending only one WHOIS or IDENTIFY command.
7395 Changed the code and the protocol specifications.
7397 * Removed silc_server_command_identify_parse and changed that IDENTIFY
7398 uses silc_server_command_whois_parse to parse the request. */
7400 * If normal server, do not parse the WHOIS and IDENTIFY requests
7401 before sending it to the router. Saves some time.
7403 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7405 * Fixed JOIN command on client library. Wrong number of arguments
7406 used to crash the client.
7408 * Added silc_server_channel_has_global function to check whether
7409 channel has global users or not.
7411 * Added silc_server_channel_has_local function to check whether channel
7412 has locally connected clients on the channel.
7414 * The silc_server_remove_from_one_channel now checks whether the
7415 channel has global users or not after given client was removed from
7416 the channel. It also checks whether the channel has local clients
7417 on the channel anymore. If it does not have then the channel entry
7418 is removed as it is not needed anymore.
7420 * The silc_server_notify now checks on JOIN notify whether the joining
7421 client is one of locally connected or global. If it is global then
7422 the channel has now global users on the channel and that is marked
7423 to the channel entry. Also, it now saves the global client to
7424 global list who is joining and JOINs it to the channel. This is
7425 for normal server, that is.
7427 Changed silc_server_send_notify_on_channel,
7428 silc_server_packet_relay_to_channel and
7429 silc_server_packet_send_to_channel check if we are normal server
7430 and client has router set (ie. global client) do not send the
7431 message to that client, as it is already routed to our router.
7433 * Implemented LEAVE notify type handling in silc_server_notify
7436 * Tested LEAVE command in router environment successfully. Tested
7437 with two routers, two servers and two clients.
7441 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
7443 * Implemented SIGNOFF notify type handling in silc_server_notify
7446 * silc_server_remove_id now removes the client entry from all channels
7447 it has joined and thusly sends SIGNOFF notify type.
7449 * Rewrote the NAMES list generation in server by removing two excess
7450 loops. The lists are created now inside one loop.
7452 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7454 * silc_server_remove_channel_user checks now also global list
7455 for channel and client.
7457 * silc_server_new_channel_user checks now both local and global
7458 list for channel and client. Fixed a bug in client id decoding.
7459 Used to decode wrong buffer.
7461 * silc_server_channel_message checks now both local and global
7462 list for channel entry.
7464 * Tested channel joining (hence JOIN) in router environment
7465 successfully. Tested with two routers, two servers and two
7468 * Tested channel message sending in router environment successfully.
7470 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7472 * Added silc_server_save_channel_key into server.[ch] to save the
7473 received channel key in Channel Key payload processing. It is
7474 also used in JOIN command reply handling.
7476 Equivalent function silc_client_save_channel_key added into
7477 client.[ch] into client library.
7479 * Changed JOIN command reply to send information whether the channel
7480 was created or not (is existing already) and the channel key
7481 payload. Changed protocol specs accordingly.
7483 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
7484 the request was sent by ID and not by nickname. Crashed on
7487 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7489 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
7490 now correctly save the received data.
7492 * silc_server_free_sock_user_data now notifies routers in the
7493 network about entities leaving the network.
7495 At the same time implemented functions silc_server_remove_id
7496 and silc_server_send_remove_id to receive and send REMOVE_ID
7497 packets. The packet is used to notify routers in the network
7498 about leaving entities. The ID removed will become invalid in
7501 * Added function silc_idlist_del_server into server. Removes and
7502 free's server entry from ID list.
7504 * silc_server_private_message function now checks, if we are router,
7505 that the destination ID really is valid ID, naturally.
7507 * In router when NEW_ID packet is received (for new client) the
7508 hash of the Client ID is saved in the ID Cache but the
7509 client->nickname is set to NULL, instead of putting the hash
7512 IDENTIFY command now also checks that client->nickname must be
7513 valid. If it is not if will request the data from the server who
7514 owns the client. Added new function
7515 silc_server_command_identify_check.
7517 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
7518 to set the command to already allocated Command Payload.
7520 * Tested private message sending in router environment with two
7521 routers, two servers and two clients. Fixed minor bugs and now
7524 * Fixed segfault from client's NAMES command. Used to crash if
7527 * Forwarded packets must not be routed even if it is not destined
7528 to the receiver. Changed server code comply with this.
7530 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7532 * Added `require_reverse_mapping' boolean value to ServerParams
7533 structure. If TRUE (not default) the server will require that
7534 the connecting host has fully qualified domain name.
7536 If the reverse mapping is not required and hostname could not be
7537 found the IP address is used as hostname.
7539 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7541 * Implemented version string checking to both client and server.
7542 The check is incomplete currently due to the abnormal version
7543 strings used in development version of SILC.
7545 * Changed all command functions in server to use the new
7548 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7550 * Changed char *data to unsigned char *data in ID Cache system to
7551 support binary data as ID Cache data. Changed code to support
7552 binary data in lib/silccore/idcache.c.
7554 * Renamed silc_server_packet_relay_command_reply to
7555 silc_server_command_reply as it is normal packet receiving
7556 function. Rewrote the function to accept command replys for
7557 servers and not only for clients.
7559 * Mark remote router always as registered server if we are connecting
7560 to it. Otherwise, commands sent by the router to us are ignored.
7562 * All ID List find routines now returns the ID Cache Entry pointer
7563 as well if requested.
7565 * WHOIS command works now in router environment, tested with two
7566 routers, two servers and two clients.
7568 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
7569 in router environment (as it is almost equivalent to WHOIS) but
7570 hasn't been tested thoroughly. Added new functions:
7572 silc_server_command_identify_parse
7573 silc_server_command_identify_send_reply
7574 silc_server_command_identify_from_client
7575 silc_server_command_identify_from_server
7577 * Disabled route cache adding because adding two different ID's with
7578 same IP replaces the old cache entry thus giving wrong route.
7579 The entry->router->connection is always the fastest route anyway
7580 so route cache may not be needed. Of course, new routes maybe
7581 established after receiving the ID when the entry->router->connection
7582 might not be anymore the most optimal.
7584 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7586 * Add route cache for received ID for fast routing.
7588 * Added silc_server_packet_route to route received packet on router
7589 that is not destined to us.
7591 * Renamed silc_server_get_route to silc_server_route_get.
7593 * Added id_string and id_string_len fields into SilcServer to
7594 include encoded ServerID for fast comparing without excess
7595 encoding of the ID's.
7597 * Cleaned up WHOIS command on server side. Added following static
7600 silc_server_command_whois_parse
7601 silc_server_command_whois_check
7602 silc_server_command_whois_send_reply
7603 silc_server_command_whois_from_client
7604 silc_server_command_whois_from_server
7606 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
7607 arguments in command replies. All command functions should be
7608 updated to use this macro.
7610 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7612 * Minor typo fixes on command reply handling on server.
7614 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7616 * Added silc_server_command_add_to_channel internal routine to add
7617 the client to the channel after router has created the channel and
7618 sent command reply to the server.
7620 * Added generic silc_server_send_command to send any command from
7623 * Use static buffer with ID rendering instead of duplicating data.
7625 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7627 * Fixed a channel user mode bug when joining to a channel server gave
7628 everybody channel founder rights, oops.
7630 * We mark ourselves as the router of the incoming server connection
7631 if we are router ourselves. This way we can check in some packet
7632 sending functions whether it is locally connected server. For
7633 incoming router connections we put NULL.
7635 * For router sending packets locally means now always sending the
7636 packet cell wide; to local clients and local servers. For normal
7637 server sending packet locally means sending it to only local
7640 * Fixed the JOIN command to really work in router environment. If the
7641 channel is created it is always created by the router. Router is
7642 also responsible of making the initial joining to the channel,
7643 sending JOIN notify to the sending server and distributing
7644 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
7645 does not exist server doesn't do anything else but forward the
7646 command to the router which performs everything.
7648 * Added silc_server_send_channel_key function to send the Channel Key
7651 * Added silc_server_create_channel_key to create new channel key. The
7652 channel key is now re-generated everytime someone joins or leaves
7653 a channel, as protocol dictates. Note: channel->key_len is the
7656 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7658 * Splitted server.[ch] finally. Created now packet_send.[ch] and
7659 packet_receive.[ch] to separate packet sending and receiving
7660 routines. The server.[ch] now includes everything else including
7661 actual packet processing (writing and reading data) and other
7664 Renamed silc_server_private_message_send_internal to
7665 silc_server_send_private_message. The routine is still though
7666 used only to relay private messages as server does not send
7667 private messages itself.
7669 Renamed silc_server_new_channel to silc_server_create_new_channel
7670 and added new function sicl_server_new_channel that handles the
7671 incoming New Channel packet. Added also new sending function
7672 silc_server_send_new_channel to send New Channel Payload.
7674 * Added new function silc_server_notify to process incoming notify
7675 packet to the server/router. Server may then relay the notify
7676 to clients if needed.
7678 * Added new function silc_server_new_channel_user to process incoming
7679 New Channel User packet. Router will redistribute the packet and
7680 send JOIN notify to its local clients and locally connected servers
7681 if needed. Normal server will send JOIN notify to its local client
7682 on same channel when received this packet. Added also corresponding
7683 sending function silc_server_send_new_channel_user to sent the
7686 * Added boolean route argument to send_notif_to_channel and
7687 packet_send_to_channel functions to attempt to route the packet
7688 if it is TRUE and send only locally if it is FALSE.
7690 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7692 * silc_server_replace_id now broadcasts the received replace ID
7693 packet if it is not broadcast packet already. The router must
7694 broadcast to inform other routers about changed ID.
7696 * Added backpointer to server's router into SilcServer context in
7697 silcd/server_internal.h.
7699 * Fixed silc_server_packet_broadcast to send correct broadcast
7702 * The channel key is now distributed to the local client as soon
7703 as it is received from the router (in router environment) so that
7704 no other packet may be sent for the channel until client has
7707 * silc_server_remove_channel_user now broadcasts the received
7708 Remove Channel User packet if it is not broadcast packet already.
7709 The router must broadcast to inform other routers about removed
7712 * Added users field into SilcPacketContext that is a reference count
7713 of the context. One can increase the reference count by calling
7714 silc_packet_context_dup which is now changed to just increase the
7715 reference count instead of duplicating the data. The reference
7716 count is decresed by calling silc_packet_context_free that will
7717 free the data after the reference count hits zero.
7719 For now on the packet context and everything allocated into it
7720 (including the raw packet from network) must be freed by calling
7721 the new silc_packet_context_free function. Added also new function
7722 silc_packet_context_alloc that must be used now to allocate the
7723 context. This also means that if a routine is asynchronous from
7724 silc_[client/server]_packet_parse_type the packet context must
7725 be duplicated by calling silc_packet_context_dup. Otherwise it
7726 gets free'd after silc_[client/server]_packet_parse_type returns.
7727 Also, one must remember that if packet is duplicated then its
7728 reference count must be decresed by calling the free function as
7729 many times as it was duplicated.
7731 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7732 from both client and server.
7734 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7736 * Made joining to a channel working in router environment.
7738 * Cleaned up JOIN command on server side and create function
7739 silc_server_command_join_channel internal routine to make the
7742 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7744 * Changed silc_command_pending list to SilcDList. Also, added
7745 `ident' field to SilcServerCommandPending structure to identify
7746 the reply and to call correct callback.
7748 Added silc_server_command_pending_check function to replace the
7749 corresnponding macro. The silc_command_pending list is not
7752 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7753 to set identifier to previously allocated Command Payload. It
7754 is used to set identifier for command when resending Command
7757 * Added silc_command_payload_encode_payload to encode Command
7758 Payload buffer from SilcCommandPayload structure.
7760 * Added silc_argument_payload_encode_payload to encode Argument
7761 payload buffer from SilcArgumentPayload structure.
7763 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7765 * Changed WHOIS command to support router connection on server side.
7766 The whois request is always sent to router unless the server is
7767 standalone server. After server has received the reply from the
7768 router will it send the reply to the client.
7770 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7771 broadcast received broadcast packet. The function is used only
7772 by router. The broadcast packet is always sent to the router's
7775 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7776 render given ID to printable string, for log files for example.
7778 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7780 * Made basic router to router connections working. At least they
7781 can now connect to each other but nothing really works the way
7782 they are supposed - yet.
7784 * Added new initiator token to RouterConnection configuration
7785 file in silcd/serverconfig.[ch]. It is used to tell whether we
7786 are the initiator to the remote router or whether we'll expect
7787 the other end to connect.
7789 * Moved registering of listener task to silc_server_init, hence
7790 the server starts listenning as soon as it is run, even if it
7791 does not have connections to other routers. Let's see how well
7794 * Changed default connection retry timeouts for more suitable in
7797 * Removed cipher and such arguments from silc_idlist_add_client
7798 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7799 Added new function silc_idlist_add_data to add the keys and stuff
7802 * Added SilcIDListData structure and added it to SilcClientEntry
7803 and SilcServerEntry as their first field in the structure. This
7804 way we can explicitly cast the ID entries to the SilcIDListData
7805 structure and get common data for the entries. In past, we had
7806 to first check what type of connection it is and then cast it to
7807 correct ID entry type. Now, we can directly cast the opaque
7808 pointer to the SilcIDListData (no matter what ID entry it actually
7809 is) and get the data needed.
7811 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7813 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7814 in some circumstances even if threre were timeout tasks, though not
7815 IO tasks, but tasks anyway. Now fixed.
7817 * Defined SilcServerConnection structure to hold connection specific
7818 stuff about directly connected servers and routers. The definition
7819 is currently in silcd/server_internal.h. I thought about having
7820 a bit more important role fro this struct but for now it is used
7821 only when connecting to other server (or router actually).
7823 * Added connecting retry support in server when connecting to
7824 router(s). The retry feature implement exponential backoff
7825 algorithm. Also, added SilcServerParams structure to hold default
7826 parameters for server. For now, it include these retry settings
7827 and are hard coded. After server is moded to be as Silc Server
7828 Library this structure will be more important.
7830 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7832 * Changed client librarys channel->clients table to SilcList and
7833 changed code accordingly.
7835 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7837 * Changed client's channel table to SilcList and changed code
7838 accordingly. Also changed SilcChannelClientEntry to include back-
7839 pointer to the channel so that client entry can use that structure
7840 as list as well and we have fast cross-reference to the channel.
7841 This change dramatically decreased the complexity of channel
7842 handling with client entry and vice versa (removed one extra
7843 loop when searching for channel entry from many functions).
7845 * Changed server->sim from table to SilcDList and changed code
7848 * NAMES command can now be used from user interface. It will show
7849 the user list on the channel, neatly.
7851 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7852 Code now saves realname of the user if it becomes available.
7854 * Renamed configure.in to configure.in.pre and made ./prepare
7855 script to automatically add correct version string to
7856 configure.in which it creates from configure.in.pre.
7858 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7860 * NAMES command reply now shows users mode with the nickname when
7863 * Moved silc_client_ch[u]mode[_char] functions from
7864 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7865 place sucks, they are utility functions and should be in some
7868 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7870 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7873 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7877 * Added TRQ (efficient deque and list library) into lib/trq. This is
7878 a very good list library that is currently used in the SILC. Defined
7879 SilcList API over the library because I didn't like the API very
7880 much. See lib/trq/silclist.h for the API and examples of how to
7881 use the API. Fixed various places in the code to use the new
7882 SilcList API. The SilcList is meant for lists that has a structure
7883 already defined as a list. It is not suitable to add just some
7884 context to the list (in TRQ, the context is the list actually).
7886 So, I defined SilcDList that can be used for the purpose where
7887 predefined list structure does not exit. This can be used as
7888 such list. Now some context just can be added to the SilcDList.
7889 Currently this list is not used in the SILC just yet, though there
7890 are a lot places where this can replace dynamically allocated
7891 tables and I will fix these places, later, to use SilcDList.
7892 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7893 and use TRQ internally).
7895 Also fixed some annoying warning messages that the original TRQ
7896 code generated. Also minor changes to TRQ's Makefile.in.
7898 * Added support for querying by Client ID to both WHOIS and
7899 IDENTIFY commands into server, as required by the protocol.
7901 * Removed method function pointers from SilcBuffer structure. They
7902 weren't used to anything and just increased the context size for
7903 no good reason. This change also made silc_buffer_alloc and
7904 silc_buffer_free functions inline functions.
7906 * Disabled command flooding detection support until it's fixed so
7907 that it accepts commands in but does not execute them more than once
7910 * Added silc_net_localhost(), to return local hostname, into
7911 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7912 that must be initialized before calling silc_client_init.
7914 * Added new function: silc_server_send_notify_on_channels to send
7915 notify messages to all channels client has joined. It is assured
7916 that the message is sent only once per client.
7918 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7919 lib/silcutil/silcutil.[ch] as silc_format function. The new
7920 function is generic and is used by server as well, not only by
7921 the logging routines.
7923 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7924 the provided version string was not acceptable. Added new function:
7925 silc_ske_check_version into lib/silcske/silcske.h. The function
7926 must be implemented by the application (client or server) and it
7927 does not reside in the SKE library. The function checks the version
7928 string remote end sent.
7930 * Added back pointers (to opaque context and to SilcSocketConnection)
7931 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7933 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7934 duplicate packet context structure.
7936 * Changed `notify' client operation to send same arguments as client
7937 receives from server except for ID's. ID's are mapped to correct
7938 ID entry and that is returned. Also, if channel entry is not sent
7939 by server but the notify is for channel the channel entry is sent
7940 to application (otherwise application doesn't know that it is for
7941 channel (library gets it from packet's Destination ID)).
7943 * Added silc_client_remove_from_channels into client library to
7944 remove a client from all channels it has joined to. Used when
7945 received SIGNOFF notify from server. Added also new function
7946 silc_client_replace_from_channels to replace old ID entry with
7947 new ID entry on all channels. Used when received NICK_CHANGE
7950 * Fixed ID Cache list handling in silc_idlist_get_client in
7951 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7952 to get (or query) client by ID.
7954 * Updated TODO list.
7956 * Added connection authentication status message defined by the
7957 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7958 support for these into the code in client and server side.
7960 * Added generic function silc_client_send_command to send any command
7961 with variable argument list. Application should use this function
7962 to send commands if the command functions provided by the library
7963 does not suite for the application's user interface needs.
7965 * Added new `failure' client operation. Application is notified about
7966 received failure packet if client is executing a protocol. In this
7967 case the protocol's execution has failed.
7969 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7970 is required by the protocol.
7972 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7973 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7976 * Added status flag to SilcSKE object to indicate realtime status
7977 of the SKE protocol.
7979 * Application receives now exactly same command reply arguments as
7980 the library receives from server. However, if ID is received the
7981 corresponding ID entry is returned to the application (eg. Client
7982 ID is mapped to correct SilcClientEntry entry and that is returned).
7983 Changed command_reply client operation due to this change.
7985 * Changed all ID's in commands and in command replys as ID Payloads.
7986 Change affected both client and server side codes.
7988 All ID's sent in SILC network (with execption of ID's in SILC
7989 Packet header) are sent in ID Payload to support variable length
7992 * Server now notifies nick changes and notifies all clients on
7993 the channels about the new nickname (about the new Client ID,
7996 * Implemented CMODE command to change channel modes. Supports all
7997 channel modes defined by the protocol specs except ban and invite
7998 lists. (Also, private channel key mode is supported but support for
7999 setting private channel key in client is missing, thus, this mode
8000 has no effect on client side (except that server requires that the
8001 client uses private channel key and normal channel traffic does not
8004 Also, invite mode works per se, but INVITE command does not work
8005 yet correctly, so you can set channel as invite only channel but
8006 inviting clients to the channel does not work (it is yet to be
8007 thought what's the best way to do it).
8009 * Added new command SILC_COMMAND_CUMODE to change user mode on the
8010 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
8011 Implemented CUMODE command to change user's mode on the channel.
8012 Supports all modes defined by the protocol specs.
8014 * Added NAMES command reply to return users modes on the channel.
8016 * Removed unnecessary and slow ciphers from lib/silccrypt.
8018 * Set SO_KEEPALIVE option to connection sockets by default.
8020 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
8022 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
8023 redefined the Notify Payload into protocol specs.
8025 * Added silc_id_payload_parse_id to get ID directly from raw
8028 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8030 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
8031 accept searching by Client ID as well.
8033 * Added support for LEAVE and SIGNOFF notify types in client library.
8035 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
8036 to parse ID Payload from raw data.
8038 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8040 * Added flags parameter into silc_ske_assemble_security_properties
8041 function in lib/silcske/silcske.[ch].
8043 * Changed notify client operation to fit better for notify messages
8044 sent by server. The notify payload received from server is now
8045 passed to the application (after parsing it to SilcNotifyPayload).
8046 It is application's responsibility to retrieve the arguments
8047 from the payload and show the message the way it wants. The message
8048 sent by server is implementation specific.
8050 * Changed public keys to comply with the protocol specification.
8051 Old public keys are not supported anymore and are not compatible.
8053 * Removed nickname from Channel Payload as the latest draft removed
8054 it. The client must resolve the nickname from the NAMES command
8055 reply received when it joined the channel.
8057 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
8059 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8061 * Fixed some errors in protocol specification drafts.
8063 * Created lib/silccore/silcnotify.c to implement Notify Payload
8064 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
8065 generic payloads described by protocol specifications. The file
8066 includes implementations for ID Payload and Argument Payload.
8068 * Changed Command Payload implementation to use the new Argument
8069 Payload. Changed command_xxxx_payload to command_payload_xxxx
8070 to comply with SILC coding conventions.
8072 * Added suppport for Argument Payload handling in Notify Payload
8073 implementation as protocol requires it. Added the new support
8074 into server and client lib as well.
8076 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8078 * Added support for multiple nicknames on same channel. [n] is
8079 added locally to the nickname if there are more than one same
8080 nicknames on the channel.
8082 * Server now sends all nicknames that matched WHOIS request.
8083 Client also shows the list received from server.
8085 * Added TOPIC command to client side. User can now set and show
8086 current topic on channel.
8088 * Added MOTD command to client and server. Also, server sends the
8089 motd when client connects to the server.
8091 * Changed version strings to comply ISO 8601.
8093 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8095 * Fixed protocol error handling in client library. It should now
8096 cope even if the SKE fails for some reason.
8098 * Made new protocol specification drafts for submitting to IETF.
8100 * Implemented TOPIC command to server in silcd/command.c.
8102 * Added two new notify types into lib/silccore/silcnotify.h:
8103 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
8104 notify nickname change and topic setting/change on a channel.
8106 * API change of command_reply operation in client library. The
8107 application gets now the status type received from server as well.
8109 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8111 * Removed the function just added to lib/silcutil/silcschedule.[ch].
8113 * Cras fixed and optimized the packet handling even further and
8114 it should work now. Minor change to the prototype of function
8115 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
8117 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8119 * Added new function into lib/silcutil/silcschedule.[ch]:
8120 silc_schedule_with_fd to select() a specified fd. The function
8121 returns after timeout expires or data arrives or goes. The
8122 function is used by packet routines to wait that all data is
8123 received from network.
8125 * Fixed data reading from network in lib/silccore/silcpacket.c.
8126 The code now assures that all data is read from the fd and then
8127 continues packet processing. This was a bug fix since the code
8128 used to drop some data in some circumstances.
8130 * Added new function into lib/silcclient/client.[ch]:
8131 silc_client_start_key_exchange to start key exchange after
8132 connection has been established to server. The code internally
8133 now uses this funtion but its main purpose was to provide it
8134 for applications that perform their own connecting. After
8135 application has created a connection it merely calls this
8136 function to start the key exchange between client and server.
8137 The library takes care of everything else after that.
8139 Updated also lib/silcclient/README to explain the usage of
8142 * Do not send to application information that connection has
8143 been established. Application gets notified it by connect
8146 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8148 * Applied cras's patch to add silc_schedule_one function. The
8149 function runs scheduler once and returns.
8151 * Fixed the scheduler after cras messed it up. The timeout
8152 handling works now as it's supposed to work.
8154 * Added into lib/silccore/ silcnotify.h to include notify
8155 message types support. Changed silc_server_send_notify*
8156 functions, in server.[ch], to support those new notify types.
8157 Added the support for the notify types into client library,
8158 as well. Added new notify client operation into ops.h in
8161 * Changed silc_server_packet_send_to_channel to send normal
8162 packets instead of just channel message packets. The function
8163 is now used to send the notify packets to channels. It is not
8164 used to send channel message packets anymore, as server never
8167 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
8168 va_arg()s as it seems to require it nowadays. I guess, if SILC
8169 is compiled with older va_arg() the new code should work anyway.
8171 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8173 * Splitted core library. Core library (lib/silccore) includes
8174 now only SILC protocol specific core (and common) components.
8175 Created new utility library (lib/silcutil) that includes more
8176 generic purpose stuff. The stuff for util library was taken
8177 from the old core library. This was minor and easy split.
8179 * Created SILC Client Library (lib/silcclient) that includes
8180 implementation of the SILC client without user interface. This
8181 was major move from silc/ directory. The code has been changed
8182 so that it is transparent towards the user interface. The
8183 silc/ directory includes now the same user interface as before
8184 and it uses the new client library. Read lib/silcclient/README.
8185 Basicly, the client library performs everything else related
8186 to SILC except user interface handling. Also, configuration
8187 files are considered to be part of user interface and library
8188 does not handle them.
8190 This change also changed a lot of structures, function naming etc.
8191 Most important change was that SilcClientWindow object was
8192 renamed to SilcClientConnection in the client library. Created
8193 also new file lib/silcclient/ops.h. Also added new files
8194 silc/local_command.[ch] and silc/client_ops.[ch].
8196 All these changes were made to make it easier for user interface
8197 designers to create what ever user interface for the SILC client
8200 It is also expected that the server will be moved to lib
8201 directory as well and SILC Server Library will be created;
8202 sometimes in the future.
8204 * Removed Local commands from lib/silccore/silccommand.h as
8205 they are application specific and new client library does not
8206 handle any of those anymore.
8208 * Several functions moved to lib/silcutil/silcutilc.[ch] from
8209 old client implementation in silc/.
8211 * Added support for callback functions in SILC_LOG_* macros.
8212 Application can now set its own callbacks that will be called
8213 instead of using the default functions that will always print
8214 the debug messages to stderr (or stdout). Also, debugging can
8215 now be disabled by setting silc_debug to FALSE and re-enabled by
8216 setting it to TRUE. Note, that logging will still work even
8217 if debugging is disabled.
8219 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
8220 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
8221 silc_log_reset_debug_callbacks.
8223 * To enable debugging in silc client one must give now -d
8224 option on command line.
8226 * Changed silc_schedule_init to automatically allocate task queues
8227 if they are not allocated before calling it.
8229 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8231 * Added GMP 3.1 into math library.
8233 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8235 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
8236 a channel in SILC network. The packet is used by servers and
8237 routers to notify other routers that user has left a channel.
8238 This little feature was missing until now. Added the feature
8239 to protocol specification as well.
8241 Added functions: silc_server_send_remove_channel_user and
8242 silc_server_remove_channel_user into server.[ch].
8244 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
8245 lib/silccore/silcpacket.h. However, they are not implemented
8248 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8250 * Fixed joining to a channel and sending channel messages
8251 between server and router. The channel message sending should
8252 now work inside a cell.
8254 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8256 * Fixed the private message sending between server and router.
8257 The private message sending should now work inside a cell.
8259 * Added silc_server_replace_id into server.[ch] to replace
8260 existing ID in the SILC network.
8262 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
8263 and silc_idlist_replace_server_id into idlist.[ch] in server.
8265 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8267 * Fixed the server to server connections. Server can again now
8268 connect to router. Router to router connections probably does
8271 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8273 * Added dynamic protocol registering support. Now protocols can
8274 registered and unregistered on the fly. Patch by cras.
8276 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8278 * Added lib/contrib directory to hold routines that some platforms
8279 don't have but are needed by SILC.
8281 * Added getopt.c, getopt1.c and getopt.h from GNU C library
8282 into lin/contrib to provide getopt() and getopt_long() for
8283 those who don't have it.
8285 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8287 * Added AWAY command to client. When away message is set and
8288 client receives a private message packet the client automatically
8289 replies to the sender with the away message.
8291 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
8292 bug seemed to be the cause of recent problems when compiling
8295 * Added version detection support to SKE protocol specification
8296 and added the new changes to the SKE implementation as well.
8297 There were other minor changes in the SKE protocol as well.
8299 Many changes in lib/silcske/silcske.[ch] and in
8300 lib/silcske/payload.[ch].
8302 * Added ^U functionality, clear input line. Patch from cras.
8304 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8306 * Mainly small bugfixes on core library. Fixed some debugging
8307 logging and buffer overflow in silclog.c.
8309 * Updated config.sub and config.guess on the distribution tree.
8311 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8313 * Added command lagging support in server. Client may execute
8314 commands now only once in two seconds.
8316 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8318 * Optimized packet reception. MAC computation and checking is now
8319 also more optimized. A lot previously duplicated code is now
8320 used as generic by both client and server.
8322 * Fixed key pair generation in clientutil.c
8324 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8326 * Added into lib/silccore/silcbufutil.[ch] new function;
8327 silc_buffer_realloc.
8329 * Moved generic packet sending/encryption functions to
8330 lib/silccore/silcpacket.[ch] from client and server. Some
8331 rewriting of the functions.
8333 * Moved all generic packet reception/decryption functions to
8334 lib/silccore/silcpacket.[ch] from client and server. The
8335 packet processing is now much cleaner in both client and server.
8336 These were major changes in both client and server.
8338 * Created many common functions in server to do packet sending.
8339 Previously code were duplicated a lot, this has been removed
8342 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8344 * Rewrote major parts of the ID cache system. Don't know
8345 whether it is better now or not but at least the API is more
8348 * Major rewrite on ID cache stuff on client because of the ID
8349 cache API changes. Added idlist.c to client.
8351 * Also major rewrite on ID cache stuff on server as well.
8352 Major rewrite of idlist.[ch]. SilcXXXList's are now named
8353 SilcXXXEntry's. We won't keep anymore idlist specific pointers
8354 in hand, instead they are all put into the ID cache system now.
8355 All server_idlist_* routines uses ID cache now instead of
8356 traversing its own lists (those lists does not exist anymore).
8357 SilcIDList though still exists. Also, SilcXXXEntry's are
8360 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8362 * Finally made the SKE implementation compliant to the protocol
8363 specification. All mp integers are now binary encoded as
8364 opposed being HEX encoded.
8366 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
8369 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
8370 functions: silc_[encode/decode]_pem. Also added function
8371 silc_encode_pem_file to PEM encode with newlines ('\n') for
8374 * SILC public keys are now encoded either PEM or binary. Same
8375 option is for private keys as well. By default private keys
8376 are binary encoded and public keys PEM encoded. Silly HEX
8377 encoding were removed.
8379 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
8380 function to create fingerprints.
8382 * Fixed a bug in SHA1; does not change the original data anymore.
8384 * Partly implemented INFO command on client and server side.
8385 Fixed CLEAR command. Changes to SERVER command; show current
8386 server(s) when giving command without arguments. Added
8387 VERSION command to client.
8389 * Added check to server that unregistered connections cannot
8390 execute commands (unless it is specificly allowed).
8392 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8394 * Fixed screen refresh.
8396 * Fixed channel joining bug from client. On some circumstances
8397 client tried to join to a channel it had already joined.
8399 * Added public key verification process into client's protocol.c.
8400 The client now verifies the public key from user and saves
8401 it into ~./silc/serverkeys/ directory.
8403 Added into: clientutil.[ch]: silc_client_verify_server_key.
8405 * Changed SKE protocol's silc_ske_initiator_finish function
8406 to accept callback function that verifies the received public
8407 key. Removed old silc_ske_verify_public_key function.
8409 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8411 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
8412 silc_pkcs_private_key[_data]_set.
8414 * Made the password and public authentication more cleaner in
8415 server's protocol.c.
8417 * Removed historic and obsolete protocol `channel_auth' from
8418 both client and server.
8420 * Removed wrong way of sending command status messages from
8421 server to client in server's command.c. The old way violated
8422 protocol specification.
8424 Changes to silccore/silccommand.[ch]: removed
8425 silc_command_encode_status_payload -> not needed anymore,
8426 changed silc_command_encode_payload_va to accept extra
8427 argument on variable argument list. The argument type must
8428 now be provided to the function. Also, added new function:
8429 silc_command_encode_reply_payload_va which is same as
8430 normal command_encode_payload_va except command status type
8431 is provided as extra argument.
8433 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8435 * Added ~./silc directory handling. The directory includes the
8436 public and private keys for the client.
8438 Added silc_client_check_silc_dir, silc_client_create_identifier
8439 and silc_client_load_keys.
8441 * Implemented SILC protocol compliant public key. Added public
8442 and private key saving to and loading from files.
8444 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
8445 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
8446 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
8447 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
8448 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
8450 Implemented: silc_pkcs_save_[public/private]_key[_data] and
8451 silc_pkcs_load_[public/private]_key.
8453 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8455 * Added silc_server_get_route (route.[ch]) to get connection
8456 data for the fastest route for given ID.
8458 * Implemented INVITE command on client and server. The command
8459 were re-defined in the SILC Protocol Specification and the
8460 implementation now complies with the specification.
8462 * Implemented PING command on client and server.
8464 * Implemented NAMES command on client and server. The server side
8465 supports currently only normal server not router server yet.
8466 Some changes to NAMES definition in SILC protocol specification.
8468 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8470 * Implemented LEAVE command on client and server.
8472 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
8473 again. This change was made to the protocol as well. Server
8474 should not violate the protocol specification anymore.
8476 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8478 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
8479 was tested. SOCKS4 was not but should work anyway.
