521 * Added the killer's client ID to the KILLED notify and added
522 it to protocol specs and implemented it to client and server.
523 Protocol TODO #13. Affected files are silcd/command.c,
524 silcd/packet_receive.c, packet_send.[ch],
525 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
526 The killer's client entry is now returned to application in
527 the `notify' client operation.
529 * Fixed the Max Argument fields that had too large value set
530 in the protocol specs. Protocol TODO #14.
532 * Added the LEAVE command reply to return the ID of parted
533 channel. Updated protocol specs and implemented it to the
534 client and server. Protocol TODO #15. Affected files are
535 silcd/command.c, lib/silcclient/command_reply.c. The channel
536 entry is now returned to application in the `command_reply'
539 * Rewrote the version SKE version checking in client libary
540 and in server to use the silc_parse_version_string. Affected
541 files are lib/silcclient/protocol.c, silcd/protocol.c.
543 * Added SILC_STATUS_ERR_NO_CHANNEL_FOPRIV error status to few
544 commands that was missing it, and updated protocol specs and
545 the server implementation. Protocol TODO #10. The affected
546 file is silcd/command.c.
548 * Defined new message flags SILC_MESSAGE_FLAG_REPLY to be
549 generic reply to a generic request (REQUEST flag), and
550 SILC_MESSAGE_FLAG_DATA to send any kind of data in a generic
551 way. A draft-riikonen-silc-flags-payloads-00.txt is written
552 to define the payload for DATA flag. Added the flags to
553 the implementation. Protocol TODO #9. Affected file is
554 lib/silccore/silcchannel.h.
556 Changed the client library to return the message length
557 to application as well in the channel_message and private_message
558 client operations. Affected files are
559 lib/silcclient/client_prvmsg, lib/silcclient/client_channel.c,
560 lib/silcclient/silcclient.h, irssi/src/silc/core/client_ops.c,
561 and lib/silcclient/client_ops_example.c.
563 * Added two new channel modes: SILC_CMODE_SILENCE_USERS
564 and SILC_CMODE_SILENCE_OPERS which can be used to moderate
565 the channel. Updated protocol specs and impelemented this
566 to client and server. Protocol TODO #6. Affected files are
567 silcd/packet_receive.c, server_util.c, lib/silcclient/command.c,
568 lib/silcclient/client_channel.c, lib/silccore/silcmode.h.
570 Added new options m and M to CMODE command in Irssi SILC
571 client to set these modes.
573 * Deprecated all administrative commands from SILC protocol
574 since they are highly implementation specific commands.
575 Updated protocol specs. Moved the old commands in
576 implementations to private range of command types. Affected
577 files are silcd/command.c, lib/silcclient/command.c and
578 lib/silcclient/command_reply.c. Protocol TODO #8.
580 * Fixed a bug in server where sending unknown command crashes
581 the server. Affected file silcd/command.c.
583 Wed Apr 3 09:57:47 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
585 * Added SILC_PROTOCOLVERSION macro to check protocol version
586 of a socket connection. The affected file is
587 lib/silcutil/silcsockconn.h.
589 * Added better error logging in rekey protocol. Affected file
592 * Do not check public key types in SKE during rekey. Affected
593 file lib/silcske/payload.c.
595 * Fixed the rekey protocol with PFS, which was totally broken.
596 Affected file silcd/protocol.c.
598 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
600 * Some client implementations quit network by doing first LEAVE
601 and then immediately SIGNOFF (like Bombyx). We now do check
602 after a short time after LEAVE notify and check whether the
603 client is still valid after LEAVE, and if not we remove it from
604 cache. Affected file is lib/silcclient/client_notify.c.
606 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
608 * Merged version 1.1.4 of zlib. Even if it not currently in use,
609 it's good not to have security holes here.
611 * Fixed a negative refcount situtuation for the config context.
612 Affected file is silcd/serverconfig.c.
614 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
616 * ROBOdoc documented lib/silcutil/silcutil.h.
618 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
620 * Optimized even more the SilcPacketContext structure. Now
621 totally saved 16 bytes of memory per context after optimization.
622 Affected files are lib/silccore/silcpacket.[ch].
624 * Made strict checks for valid SILC IDs. Affected file is
625 lib/silccore/silcid.c.
627 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
629 * Changed the object argument for silc_cipher_register,
630 silc_hash_register, silc_hmac_register and silc_pkcs_register
631 to const. Affected files are lib/silccrypt/silccipher.[ch],
632 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
634 * Changed the silc_get_username and silc_get_real_name to
635 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
637 * Fixed the Irssi SILC Client to use the silc_get_username and
638 silc_get_real_name insted of glib routines since the glib
639 routines only corrupt stack. Fixes the Irssi SILC to work in
640 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
642 * Fixed the Irssi to not use g_get_home_dir since it crashes
643 or returns garbage on cygwin and corrupts stack. Added function
644 get_home_dir to Irssi routines. Affected files are
645 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
647 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
649 * Made some structure optimizations. SFTP memory FS MemFSEntry
650 entry structure. Optimized SilcTask structure. Optimized
651 SilcPacketContext structure.
653 Affected files lib/silcsftp/sftp_fs_memory.c,
654 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
656 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
658 * And yet again reverted back the config thing since Johnny
659 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
662 * Fixed memory leaks from config object. Affected files are
663 silcd/serverconfig.[ch].
665 * Added support for adding new connections to the server in rehash.
666 After rehash they take effect.
668 Added support for changing the maximum allowed connections in
669 rehash. The number can grow but going smaller is not supported.
671 Added function silc_server_num_sockets_by_remote to the
672 silcd/server_util.[ch].
674 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
676 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
678 * Added preliminary checking during config parsing for a valid
679 public/private key and removed further checks in the code.
680 Affected files are silcd/serverconfig.[ch], server.c.
682 * Moved functions silc_server_drop() and silc_server_daemonise()
683 from server.c to silcd.c since they are stricly related to
684 the application activity.
686 * Reverted a small part of the automatic ref/unref since
687 it caused a double unref in some situations. Affected
688 files are silcd/silcd.[ch], server.c, serverconfig.c.
690 * Added some .cvsignore files in the lib directory.
692 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
694 * Fixed silc_net_gethostbyaddr to correctly resolve by
695 address. Affected file lib/silcutil/silcnet.c.
697 * Fixed the notify relaying to client. The HMAC to be used
698 with relayed packets ws wrong and caused decryption failure
699 at the client end. Affected file is silcd/packet_receive.c.
701 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
703 * Created new branch silc_protocol_1_0_branch.
705 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
707 * Changed the silc_server_config_* routines to be SilcServer
708 independent. They are now officially application specific code
709 and not part of generic server implementation. Affected files
710 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
712 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
714 * Added automatic referencing of config context in the
715 silc_server_config_alloc, and automatic unreferencing in the
716 silc_server_config_destroy. Affected files are
717 silcd/serverconfig.[ch], silcd/silcd.c.
719 * Fixed the silc_log_quick handling in the logging routines.
720 It didn't log quickly when it was TRUE. Affected file is
721 lib/silcutil/silclog.c. Also the flush delay was set even
722 if it was 0 in config file. Affected file is
723 silcd/serverconfig.c.
725 * Added support for changing key pair of the server in rehash.
726 Affected file silcd/server.c.
728 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
730 * Fixed the TOPIC_SET notify to not cras. It changed the topic
731 too early, before getting the channel entry. Affected file
732 is silcd/packet_receive.c.
734 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
736 * Added functions silc_server_config_[ref/unref], these are used
737 to prevent that the config object is destroyed.
739 No longer directly affect global variables silc_log_quick and
740 silc_log_delay, they are first cached inside the config object
741 and then applied with silc_server_config_setlogfiles().
743 silc_server_config_set_defaults() is now internal to
744 serverconfig.c, there are no reasons to show this internal stuff
747 Affected files are silcd/serverconfig.[ch].
749 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
750 fprintf's to stderr, since some code may be executed again after
751 the server went into the background. Affected files are
754 * Added rehash support. Added function silc_server_rehash() that
755 will perform all the basic tasks of the rehashing procedure.
757 * Added command line option `-x, --hexdump'. This will enable the
758 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
759 The option `--hexdump' implies `--debug'.
761 * Fixed a bad bug in the logging APIs (silcutil library) where
762 the application would crash after calling silc_log_reset_all().
764 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
766 * Fixed the KICKED notify handling in client library to
767 correctly remove the channel and all entries from the
768 channel when I was kicked. This bug crashed the client.
770 Fixed yet another but in KICKED notify handling to remove
771 the kicked client correctly from the channel.
773 Affected file is lib/silcclient/client_notify.c.
775 * Fixed a minor bug in looking up correct client entry
776 in KICKED notify in server. Affected file is
777 silcd/packet_receive.c.
779 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
780 sources correctly to distribution. Fixes --with-gmp option.
782 * Removed the manual rehashing from ID Cache, and changed it
783 to use the SILC Hash Table's auto rehash feature. Affected
784 file is lib/silccore/silcidcache.c.
786 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
788 * Fixed a bug in the silc_client_nickname_format function that
789 handles the multiple same nickname formatting. Two clients
790 with same nickname caused problems after the first one left
791 and rejoined. It didn't format the nickname correctly.
792 Affected file is lib/silcclient/idlist.c.
794 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
796 * Don't change the topic if olod topic is same as new one.
797 Affected file is silcd/packet_receive.c.
799 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
801 * Added cross-reference support to the SILC Documentation
802 generator. All types across all HTML files are now cross-
803 referenced. Affected files util/robodoc/generator.c and
804 scripts/silcdoc/silcdoc.
806 * Added file lib/silcutil/silctypes.h to include all the
807 arithmetic type definitions and some macros. Removed
808 includes/bitmove.h and moved macros to silctypes.h.
810 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
812 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
814 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
816 * Added `type' argument to silc_id_payload_parse_id function which
817 now returns the type of the ID to the sent pointer. Affected
818 file is lib/silccore/silcid.[ch].
820 * Added check for CMODE_CHANGE notify type that mode change is
821 allowed by the sender. Affected file silcd/packet_receive.c.
823 * Added check for CUMODE_CHANGE notify type that mode change is
824 allowed by the sender. Affected file silcd/packet_receive.c.
825 Added the ID type as CUMODE_CHANGE notify type as argument
826 to the `notify' client operation. Affected files are
827 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
829 * Added function silc_client_add_server to the client library.
830 Added support for resolving also channel and server info when
831 received unknown entity in notify packet. Affected files are
832 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
834 * Added function silc_command_get_status to return the command
835 status from the command reply's argument payload. Affected files
836 are lib/silccore/silccommand.[ch].
838 * Added check for KICKED notify type that the kicking is
839 allowed by the client. Affected file silcd/packet_receive.c.
841 * Created function silc_get_input which can be used to get input
842 (echo on or off) from user on command line. Affected files are
843 lib/silcutil/silcutil.[ch].
845 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
847 * Optimized silc_server_packet_relay_to_channel function.
848 Added new function silc_channel_message_payload_encrypt which
849 can be called directly if channel message payload needs to
850 be encrypted and is already encoded (no need to call _encode
851 function). Packet relaying is now done by router without any
852 extra memory allocations. Affected files are
853 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
856 * Fixed the INVITE notify handling. It took wrong arguments
857 as invite list and invite delete. Affected file is
858 silcd/packet_receive.c.
860 * Added check for TOPIC_SET notify type that the topic change is
861 allowed by the client. Affected file silcd/packet_receive.c.
863 * Added check for INVITE notify type that inviting is allowed by
864 the client. Affected file silcd/packet_receive.c.
866 * Changed the silc_server_client_on_channel to return the
867 SilcChannelClientEntry as well. Moved the function
868 silc_server_check_cmode_rights to server_util.[ch].
869 Affected files are silcd/server_util.[ch], silcd/command.c.
871 * Added function silc_server_check_umode_rights to check whether
872 changing client's user mode is allowed. Added check for
873 UMODE_CHANGE notify type that the umode change is allowed
874 by the client. Affected files are silcd/server_util.[ch],
875 silcd/packet_receive.c and silcd/command.c.
877 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
879 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
880 ID length. It ignored that ID can be IPv6 based as well.
881 Affected file lib/silccore/silcpacket.h.
883 * Fixed the silc_id_id2str and silc_id_str2id to take the
884 IPv6 address offset's into consideration. Affecte file is
885 lib/silccore/silcid.c.
887 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
889 * Fixed the internal Unix scheduler functions to check for
890 NULL context they may receive. The affected file is
891 lib/silcutil/unix/silcunixschedule.c.
893 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
895 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
896 can specify different directory with --home command line
897 parameter. Affected files irssi/src/silc/core/client_ops.c,
900 * SILC-specific commands aren't now executed if the active server
901 isn't of SILC-type, so there won't be problems with having
902 IRC and SILC protocol support in same client. Affected files
903 irssi/src/silc/core/silc-channels.c, silc-servers.c,
906 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
908 * Improved the signal support in SILC Schedule. Added new
909 function silc_schedule_signal_call which is used by application
910 to mark a signal to be called. It is now safe to perform
911 any kind of tasks in signal callbacks since it is guaranteed
912 that the application specified signal callback is called
913 after the signal is over. Affected files are
914 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
916 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
918 * Added `name' field to SilcChannelPrivateKey to represent
919 application given name for the key. Moved also the context from
920 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
921 Added the `name' argument also to the function
922 silc_client_add_channel_private_key.
924 Added function silc_client_current_channel_private_key to set the
925 current channel private key in use.
927 Added "change" command to KEY command which can be used to change
928 the current channel private key. Bound the command also to
931 Also affected files lib/silcclient/client_channel.c,
932 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
934 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
936 * Added silc_rng_get_byte_fast function in to the
937 lib/silccrypt/silcrng.[ch].
939 * Changed the interface of silc_packet_assemble and the
940 silc_packet_send_prepare. If silc_packet_assmble is now
941 called the application does not call silc_packet_send_prepare
942 because the library will call it automatically. These
943 interfaces now also return a reference to the outgoing buffer
944 which includes the assembled packet, which the application can
945 use to encrypt the packet.
947 Affected files are lib/silccore/silcpacket.[ch],
948 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
949 silcd/packet_send.c, server_backup.c and packet_receive.c.
951 * Fixed a packet sending bug on very high load, where outgoing
952 packet queue wasn't handled correctly and packets got corrupted.
953 Affected files are lib/silcutil/*/silc*sockconn.c,
954 lib/silcclient/client.c and silcd/server.c.
956 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
958 * Added macro SILC_PACKET_DATALEN which can be used during
959 packet assembling to check whether the data to be added to
960 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
961 len is truncated until it fits it.
963 Added checks for maximum length of channel message payload and
964 private message payload also.
966 Added checks for maximum packet length in server and in
969 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
970 lib/silcclient/client.c, lib/silccore/silcchannel.c and
971 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
972 lib/silcclient/client_prvmsg.c.
974 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
976 * Added silc_server_packet_queue_purge call to the
977 silc_server_disconnect_remote to assure that all data in the
978 queue before disconnecting is sent to the network. Affected
981 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
983 * Added the deleting of server's own ID cache entry to the
984 silc_server_free function. Free also everything else that
985 has been allocated in silc_server_init. The affected file
988 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
990 * Added functions silc_parse_version_string, silc_version_to_num,
991 and silc_ske_parse_version to parse SILC protocol style version
992 strings. Affected files lib/silcutil/silcutil.[ch] and
993 lib/silcske/silcske.[ch].
995 * Added new configuration params: version_protocol, version_software
996 and version_software_vendor to specify what version the remote
997 host must at least be to be able to connect to server. The vendor
998 string can be regex matched too. Added new function
999 silc_server_connection_allowed to check maximum number of allowed
1000 connections, and allowed versions for incoming connections.
1001 Affected files are silcd/server.c, server_util.[ch] and
1004 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1006 * Added preliminary support for signals in scheduler. The
1007 signals we care about are now blocked always when the scheduler
1008 is locked. This way we can synchronise the use of signal with
1009 scheduler. It is guaranteed that when signal occurs the scheduler
1010 is not locked, and thus new tasks can be safely added to the
1013 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
1014 to silc_schedule_internal_init and silc_schedule_internal_uninit.
1015 Added new platform specific routines
1016 silc_schedule_internal_signals_[un]block and
1017 silc_schedule_internal_signal_[un]register.
1019 Added new functions to SILC Schedule API:
1020 silc_schedule_signal_[un]register. Each signal that application
1021 is going to use should be registered to the scheduler.
1023 Affected files are lib/silcutil/silcschedule.[ch],
1024 lib/silcutil/*/silc*schedule.c.
1026 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1028 * Check for unauthenticated client and server in the
1029 silc_server_new_client and silc_server_new_server functions.
1030 Affected file silcd/packet_receive.c.
1032 * Added function silc_string_is_ascii to check whether given
1033 string is 7-bit ASCII string. Affected files are
1034 lib/silcutil/silcutil.[ch].
1036 * Added function silc_id_is_valid_server_id into the
1037 silcd/serverid.c and added checking for valid Server ID's in
1038 silc_server_new_server. The Server ID must always be based
1039 on the server's public IP address.
1041 * Added logging of DISCONNECT packet message in the server.
1042 Affected file silcd/server.c.
1044 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1046 * Changed all library interfaces that use Global RNG to also
1047 accept SilcRng as argument. Affected files are
1048 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
1049 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
1050 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
1051 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
1052 lib/silccrypt/rsa.c.
1054 * Added function silc_pkcs_generate_key to the
1055 lib/silccrypt/silcpkcs.[ch] for applications so that they
1056 don't need to do pkcs->pkcs->init calls anymore.
1058 * Remove SilcSocketConnection from the SFTP API since it really
1059 wasn't needed there. The application has the information
1060 saved in its contexts anyway and the SFTP layer doesn't need
1061 know about it. Affected files lib/silcsft/silcsftp.h and
1062 lib/silcsftp/sftp_[server/client].c.
1064 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
1065 The SilcSimContext is not SilcSim.
1067 * Fixed possible buffer overflows in silc_id_render in the
1068 lib/silcutil/silcutil.c.
1070 * On EPOC the global crypto module lists are not used at all
1071 in the crypto library. Added support for using the constant
1072 algorithm list on EPOC. Affected files are
1073 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
1076 * Fixed the handling of third parameter of KICKED notify, since
1077 it was mistakenly updated to SILC Protocol 1.0 even though it
1078 is to be included in 1.1. Since it is not in 1.0 it is not
1079 mandatory, and this fix now handles it only if it is provided,
1080 and it is not error if it is not provided. Affected file
1081 lib/silcclient/client_notify.c.
1083 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1085 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
1086 client. Affected file irssi/src/silc/core/client_ops.c.
1088 * Merged with Irssi 0.8.4 from irssi.org CVS.
1090 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1092 * Check for valid socket connection in client entries before
1093 sending any messages. Fixes a crash, but doesn't fix some
1094 other underlaying bug that is lurking there. Affected
1095 file silcd/packet_send.c.
1097 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
1099 * $usermode, $cumode and $cumode_space expandos shouldn't do
1100 anything with non-SILC server records. Affected file
1101 irssi/src/silc/core/silc-expandos.c
1103 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1105 * Fixed the silc_net_check_[host/local]_by_sock to support
1106 IPv6 bound sockets as well. Now they can return IPv6 addresses
1107 as well. Affected file lib/silcutil/silcnet.c.
1109 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
1110 Affected lib/silcutil/unix/silcunixnet.c.
1112 * Fixed ID rendering (at least on some platforms, not NetBSD)
1113 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
1115 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1117 * Added silc_hash_public_key and silc_hash_public_key_compare
1118 functions to be used with SilcHashTable. They can be used to
1119 hash public keys and compare public keys in hash table. Affected
1120 file lib/silcutil/silcutil.[ch].
1122 * Added support for specifying multiple public keys for Client
1123 connection section in server configuration file. This makes it
1124 possible to accept multiple public keys from same host, or to
1125 make a section that accepts any incoming host, and have the
1126 accepted public keys listed in the section.
1128 Added functions silc_sever_[find/get]_public_key, added the
1129 support for this actually to all connection sections but only
1130 the Client section is currently allowed to specify multiple
1133 Affected files are silcd/server.c, server_internal.h,
1134 command.c, protocol.c, server_util.[ch], packet_receive.c.
1136 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1140 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1142 * If silc_debug is TRUE, also output standard logging messages
1143 to stderr with the debug output.
1145 Made silc_log_reset_all() flushing all channels before returning.
1146 Also fixed some documentation typos.
1148 Affected files are lib/silcutil/silclog.[ch].
1150 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1152 * Fixed the server to check correctly the amount of connections
1153 from single host, by checking also the type of the connection.
1154 Fixed also the comparison of number of connections and number
1155 of allowed connections. Affected files are silcd/server.c,
1158 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1160 * Fixed the USERS command reply to save the user's mode on the
1161 channel as well. Fixed JOIN command reply to check whether a
1162 client is on channel already and not join it twice. Affected
1163 file lib/silcclient/command_reply.c.
1165 * Added new file silc-expandos.c into irssi/silc/core/ to return
1166 various stuff for various signal for the statusbar etc. updating.
1167 Now Irssi SILC client prints channel user modes etc. on the
1170 * The user mode (like server/router operator changes) is now shown
1171 on the Irssi SILC client's statusbar. The affected files are
1172 irssi/src/silc/core/client_ops.c, silc-expandos.c.
1174 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1176 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
1177 to SILC_SCHEDULE_[UN]LOCK macros.
1179 * Added more error printing to logs in server code. Affected
1180 files silcd/server.c and silcd/protocol.c.
1182 * Fixed -S option parsing in Irssi SILC Client. Affected file
1183 irssi/src/silc/core/silc-core.c.
1185 * Added silc_buffer_alloc_size function. Affected file is

1210 * Changed all integer type names:
1211 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
1212 to avoid collisions with other libraries using same type names
1215 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1217 * Added `prefer_ipv6' argument to the functions
1218 silc_net_gethostbyname[_async]. If it is TRUE it will return
1219 IPv6 address over IPv4. If FALSE IPv4 address is returned
1220 even if IPv6 address was found. Affected files
1221 lib/silcutil/silcnet.[ch].
1223 * Added support silc_net_create_connection[_async] to fallback
1224 to IPv4 address if IPv6 address could not be used (like if
1225 it doesn't work on a specific system). Affected file in
1226 lib/silcutil/unix/silcunixnet.c.
1228 Sat Feb 23 15:20:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1234 Wed Feb 20 20:41:01 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1236 * Added automatic extern "C" { ... } for C++ compilers so the
1237 application does not need to define them. Affected file
1238 includes/silcincludes.h.
1240 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
1241 old name went against naming convention. Applications now
1242 include "silcclient.h" instead of "clientlibincludes.h".
1243 Removed includes/clientlibincludes.h, it is redundant now.
1245 * Renamed includes/version.h to silcversion.h.
1247 * Added really preliminary support for OS/2 into the util
1248 library. Only thread & mutex API is implemented, others
1249 are still to be implemented. Created the lib/silcutil/os2/
1250 directory. Created also file includes/silcos2.h.
1252 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1283 * Added `user_count' to the SilcChannelEntry which now tells the
1284 number of users on the channel. The user count is now saved
1285 in normal server of global channels as well. Affected files
1286 silcd/server.c, idlist.h, packet_receive.c and command.c.
1288 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
1289 include file utility functions.
1291 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
1292 instead of calling directly OS routines.
1294 * Fixed NICK change printing in Irssi SILC Client. Fixed
1295 KICKED notify printing in Irssi SILC Client. Affected file
1296 irssi/src/silc/core/client_ops.c.

1299 client_entry->channels hash table everytime nick is changed.
1300 Affected file lib/silcclient/client.c.
1302 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1304 * ROBOdoc documented the lib/silcske/silcske.h, and improved
1305 the SKE interface a bit.
1307 * Fixed padding problem in PKCS#1. The padding was not actually
1308 random since the random number generator was used incorrectly.
1309 This security bug affects only when encrypting with PKCS#1, and
1310 it is not currently used at all in SILC. SILC only use signing
1311 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
1313 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1371 is now done in silc_core_init() which also fixes autoconnecting
1374 Affected files irssi/src/silc/core/silc-core.c,
1375 irssi/src/fe-text/silc.c.
1377 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1379 * Added new configuration options and blocks:
1380 keepalive_secs, reconnect_count, reconnect_interval,
1381 reconnect_interval_max, reconnect_keep_trying and
1382 require_reverser_lookup. Added ConnectionParam block, and
1383 implemented the connection parameters when connecting as
1384 initiator and when accepting connections as responder.
1386 Added CONFIG_IS_DOUBLE macro in config file parsing, to check
1387 whether given configuration value has been given already.
1389 Affected files silcd/serverconfig.[c], server.[c].
1391 * Splitted the doc/example_silcd.conf.in. Separated the crypto
1392 algorithm parts and created new file silcalgs.conf, that
1393 is now included from the example_silcd.conf.in.
1395 * Optimized the silc_server_connect_to_router_second to take
1396 the connection configuration object from the SilcServerConnection
1397 object instead of finding it during the connecting phase.
1398 Added the configuration object to SilcServerConnection struct.
1399 Affected files silcd/server_internal.h, server.c.
1401 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1403 * Add the client on channel after it was resolved at the
1404 channel message receiving, and it was not already on the
1405 channel. Affected file lib/silcclient/client_channel.c.
1407 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1422 config file, allowing both public key and passphrase based
1423 authentication to be set at the same time.
1425 Added `prefer_passphrase_auth' setting in config file which
1426 can be used to set to prefer passwd auth if both passwd and
1427 public key is set. If not set, public key is preferred.
1428 This has effect only when being initiator (responder will try
1431 Added support for authentication with passphrase and public key
1432 at the same time. The passphrase is tried first always since
1433 it is faster to check.
1435 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
1437 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

1483 * Fixed the file transfer's key agreement payload to include
1484 zero port also if the hostname is NULL because it could not
1487 Call file transfer monitor callback now also if error occurs
1488 during key agreement protocol.
1490 Changed the silc_client_file_send interface to return the
1491 SilcClientFileError instead of session id. The session ID
1492 is returned into pointer provided as argument.

1509 file lib/silcutil/silclog.c.
1511 * Fixed the channel message payload decryption in the function
1512 silc_channel_message_payload_decrypt to not modify the original
1513 buffer before it is verified that the message decrypted
1514 correctly. Otherwise, next time it is called with correct
1515 channel key it won't encrypt since the payload is corrupted.
1516 Affected file lib/silccore/silcchannel.c.
1518 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1532 become invalid in the callback but it was referenced after
1533 the callback returned.
1535 Do not allow auto rehashing of hash table during the
1536 silc_hash_table_foreach operation, for same reasons as it is
1537 not allowed for SilcHashTableList. Affected files are
1538 lib/silcutil/silchashtable.[ch].

1554 * Added function silc_client_add_channel,
1555 silc_client_replace_channel_id, and removed functions
1556 silc_client_new_channel_id and silc_idlist_get_channel_by_id
1557 from client library.
1559 * Added cross reference of the joined channels to the
1560 SilcClientEntry, and changed the SilcChannelEntry's
1561 users list to SilcHashTable. The affected files are
1562 lib/silcclient/idlist.[ch].
1564 * Fixed a bug in hash table tarversing. While the hash table
1565 is traversed with SilcHashTableList the table must not be
1566 rehashed. It is now guaranteed that auto rehashable tables
1567 are not rehashed while tarversing the list. Also defined that
1568 silc_hash_table_rehash must not be called while tarversing
1569 the table. Added function silc_hash_table_list_reset that must
1570 be called after the tarversing is over. The affected files are
1571 lib/silcutil/silchashtable.[ch].
1573 * Changed all hash table traversing to call the new
1574 silc_hash_table_list_reset in server and in client library.
1576 * Added function silc_client_on_channel to return the
1577 SilcChannelUser entry if the specified client entry is joined
1578 on the specified channel. This is exported to application as
1579 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
1581 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1583 * Fixed founder regaining problem with JOIN command on normal
1584 server. The notify for mode change must be sent always and
1585 not only if !cmd->pending. Affected file silcd/command.c.
1587 * Fixed the WHOWAS command's reply sending to support the
1588 lists correctly. Affected file silcd/command.c.
1590 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1592 * When sending JOIN command to router for processing the
1593 sender's old command identifier was not saved back to the
1594 sender's command context, fixed now. The affected file is
1597 * Create the key in JOIN command of the router did not return
1598 the channel key, added check for this. Affected file is
1601 * Fixed a channel ID update bug in JOIN command reply. Do
1602 not directly upgrade the ID but call the function
1603 silc_idlist_replace_channel_id if the ID was changed.
1604 Affected file silcd/command_reply.c.
1606 * Fixed memory leaks from command calling if it would fail.
1607 Affected file silcd/command.c.
1609 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1611 * Applied patches from cras:
1613 Memory leak fixes around libaries, irssi window resize fix,
1614 new silclist.h and silcdlist.h, all extern inline changed to
1617 * Removed dotconf from lib/dotconf, not needed anymore.
1619 * Removed TRQ from lib/trq, not needed anymore.
1621 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
1622 with server connections. Later this will be configurable
1623 in config file after new config file is done. Affected file
1626 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1628 * Fixed a crash in server related to channel announcements.
1629 Affected file silcd/server.c.
1631 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1633 * Fixed memory leaks in silc_server_create_new_channel*
1634 functions. Affected file silcd/server.c.
1636 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
1637 which ID was changed. This way the router will send the
1638 user list for the channel again, and server won't be in
1639 desync in some rare circumstances. Affected file is
1640 silcd/packet_receive.c.
1642 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1644 * Check for NULL socket pointer in the function
1645 silc_server_packet_send_to_channel_real. Affected file
1646 silcd/packet_send.c.
1648 * Fixed the BAN notify handling to correctly remove ban
1649 list. Affected file silcd/packet_receive.c.
1651 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1653 * Fixed some header addition to Toolkit distribution in
1654 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
1656 * Added lib/silcclient/client_ops_example.h as an template
1657 file for application programmers to quickly start using
1658 the SilcClientOperation functions in their application.
1659 Updated the lib/silcclient/README as well to tell about this
1660 nice file made available.
1662 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1664 * Call silc_server_remove_from_channels when removing client
1665 entry when NO_SUCH_CLIENT_ID was received. Affected file
1666 is silcd/command_reply.c.
1668 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1670 * Added server & router operator statistics updating. Affected
1671 file silcd/packet_receive.c and silcd/command.c.
1673 * Fixed the SERVER_SIGNOFF notify handling on normal server
1674 not to save the history information for clients. Same was
1675 fixed earlier in remove_clients_by_server function, but not
1676 here. Affected file silcd/packet_receive.c.
1678 * Raised the default connection-retry count from 4 to 7 in
1679 server. Affected file silcd/server.h.
1681 * Cancel any possible reconnect timeouts when we start the
1682 key exchange. Affected file silcd/server.c.
1684 * Do not reconnect on connection failure when SCONNECT was
1685 given. Affected files silcd/server.[ch].
1687 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1689 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
1691 * Fixed the NICK command to always give the unformatted
1692 nickname to the one giving the NICK command. If unformatted
1693 nickname is cached already it will be formatted and the
1694 local entry will always get the unformatted nickname.
1695 Affected file lib/silcclient/idlist.c.
1697 * Fixed some double frees from client library commands.
1698 Affected file is lib/silcclient/command.c.
1700 * Fixed CUMODE command in server to assure that no one can
1701 change founder's mode than the founder itself, there was a
1702 little bug. Affected file silcd/command.c.
1704 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1706 * Removed the SilcClientCommandDestructor from the client
1707 libary, it is not needed anymore. Affected files are
1708 lib/silcclient/silcapi.h, command[_reply].[ch],
1709 client_notify, idlist.c.
1711 * Fixed GETKEY command to first resolve client, and then
1712 resolve the server only if the client was not found, instead
1713 of resolving both at the same time. Affected file is
1714 lib/silcclient/command.c.
1716 * Added silc_client_start_key_exchange_cb and lookup the
1717 remote hostname and IP address before starting the key
1718 exchange with server. The affected file is
1719 lib/silcclient/client.c.
1721 * The server's public key is now saved using the IP address
1722 of the server and not the servername for the filename.
1723 The hostname public key filename is checked as an fall back
1724 method if the IP address based filename is not found.
1726 Fixed the GETKEY command to save the fetched server key
1727 in correct filename.
1729 Print the remote server's hostname now when new key is
1730 received during connection process. Affected file is
1731 irssi/src/silc/core/client_ops.c.
1733 * Return always our own public key to the client if it asks
1734 for it with GETKEY command. Affected file silcd/command.c.
1736 * Removed the use_auto_addr variable from default config
1737 file since it was in wrong section. Affected file is
1740 * Fixed TOPIC_CHANGE notification to not route it when it
1741 was sent using silc_server_send_notify_to_channel function.
1742 Affected file silcd/command.c.
1744 * Fixed silc_server_send_notify_kicked to send the kicker's
1745 Client ID also, it was missing. Affected files are
1746 silcd/command.c, silcd/packet_send.[ch].
1748 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1750 * Do not save client history information in SERVER_SIGNOFF.
1751 Fixes the bug in normal server that it does not detect
1752 the client becoming valid after the server becomes back
1753 online. Affected file silcd/server_util.c.
1755 * Added `sock_error' field into the SilcSocketConnection
1756 context. When error occurs during socket operation (read
1757 or write) the error is saved. Added also new function
1758 silc_socket_get_error to return human readable socket error
1759 message. Affected files are lib/silcutil/silcsockconn.[ch],
1760 lib/silcutil/unix/silcunixsockconn.c, and
1761 lib/silcutil/win32/silcwin32sockconn.c.
1763 * The server now prints the socket error message in the
1764 signoff for client. Affected file silcd/server.c.
1766 * Fixed the `created' channel information sending from router
1767 to server in JOIN command. Checks now whether the channel
1768 really was created or not and set it according that.
1770 Fixed the JOIN command to use the client entry's current
1771 ID during the joining procedure instead of the one it sent
1772 in the command (it is checked though), since it can change
1773 between the packet processing and command processing, and
1774 would just case unnecessary pain in the client end. Affected
1775 file silcd/command.c.
1777 * Fixed a channel key payload sending to use correct channel
1778 ID when the server was forced to change the channel's ID by
1779 router. Router sent the key payload with the old Channel ID.
1780 Affected file silcd/packet_receive.c.
1782 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1784 * Call silc_server_save_channel_key only if the key payload
1785 was provided in the JOIN command's command reply. Affected
1786 file silcd/command_reply.c.
1788 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1790 * Fixed silc_mp_sizeinbase to return the value correctly with
1791 MPI. Affected file lib/silcmath/mp_mpi.c.
1793 * Fixed the stop_server signal to correctly stop the scheduler
1794 and gracefully stop the server when SIGTERM or SIGINT signals
1795 are received. Affected file silcd/silcd.c.
1797 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1799 * Simple handling of TERM and HUP signals. Also added some log
1800 flushing call around. Affected file is
1803 * Fixed small bugs in silclog.c. Now buffering output will take
1804 effect after 10 seconds since startup: This will ensure that
1805 no important startup messages are lost. Also output redirection
1806 will preserve original format ([Date] [Type] message).
1807 Affected file is lib/silcutil/silclog.c.
1809 * Added two options to the config file, in the logging section:
1810 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1811 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1813 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1815 * Do not print the warning about log files not being initialized
1816 more than once to avoid excess logging. Affected file is
1817 lib/silcutil/silclog.c.
1819 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1820 the SIM copying in make install in Makefile.am.pre.
1822 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1824 * Rewritten silclog APIs. Globally interesting changes follows:
1825 silc_log_set_files() changed to silc_log_set_file().
1826 silc_log_set_callbacks() changed to silc_log_set_callback().
1827 ROBOdoc documented silclog header file.
1828 SilcLogCb now returns bool to wether inihibit the default
1829 handler or not (to keep the old behaviour return always TRUE).
1830 The new APIs should also fix the problem of the
1831 silcd_error.log file that was written in the current directory.
1834 Log files streams will remain opened after silc_log_set_file()
1835 call, means less CPU usage notably on high traffic servers.
1836 File streams are now full buffered, and flushed to the disk
1837 every 5 minutes, lesses HD activity and CPU usage.
1838 Messages can be redirected, allowing admins to configure
1839 one single logfile for all server messages.
1840 the silc_log_quick global variable to activate fast-logging.
1841 Affected files lib/silcutil/silclog.[ch]
1843 * Changed some code to conform new silclog APIs. Affected
1844 files are doc/example_silcd.conf.in, silcd/server.c
1845 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1848 * Fixed a memory leak that could occur in some situations.
1849 Affected file silcd/serverconfig.c.
1851 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1853 * Added the silc_client_del_client to remove the client from
1854 all channels as well. Affected file lib/silcclient/idlist.c.
1856 * Fixed the client library to correctly remove the client
1857 from all channels when the client entry is being destroyed.
1858 Affected file lib/silcclient/client_notify.c, command.c.
1860 * Added auto-nicking support to the client library. If the
1861 applicatio now sets client->nickname it will be sent to the
1862 server after connecting by the library. This way for example
1863 SILCNICK (or IRCNICK) environment variables will have effect
1864 and always change the nickname automatically to whatever
1865 it is wanted. Affected file lib/silcclient/client.[ch].
1867 * Renamed silc_server_command_bad_chars to the
1868 silc_server_name_bad_chars and moved it to the
1869 silcd/server_util.[ch]. Added also new function
1870 silc_server_name_modify_bad to return nickname that
1871 includes bad characters as new nickname without those
1872 bad characters. This check and modify is now used in
1873 silc_server_new_client when the username is initially set
1874 as nickname, so it must be checked to be valid nickname.
1875 Affected file silcd/packet_receive.c.
1877 * The nickname length is now taken from the packet for real
1878 and not trusted to strlen() since it clearly can return
1879 wrong length for nickname including bad characters. This
1880 also applies to channel names. Affected file silcd/command.c.
1882 * Removed the lib/silcsilm/modules directory. Modules are now
1883 compiled into the lib/silcsim. Fixed the copying of the
1884 modules to follow symbolic links in Makefile.am.pre.
1886 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1888 * Fixed silc_string_regexify list creation. Fixes bugs with
1889 BAN and INVITE commands in server. The affected file is
1890 lib/silcutil/unix/silcunixutil.c.
1892 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1894 * Removed the command destructor entirely from the server's
1895 command and command reply routines. It is not needed, and
1896 its usage was buggy and caused crashes. Affected files are
1897 silcd/command[_reply].[ch].
1899 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1901 * Cancel protocol and NULL sock->protocol if timeout
1902 occurred during protocol. Affected file silcd/server.c.
1904 * Cancel protocol timeouts always before calling the final
1905 callback, to assure that after final callback is called
1906 no other state will be called for the protocol anymore.
1907 Affected file silcd/protocol.c.
1909 * Print error log if incoming connection configuration could
1910 not be found. Affected file silcd/server.c.
1912 * Fixed JOIN command to correctly save the founder mode
1913 to the client on normal SILC server, when the channel
1914 was created by the router. Affected file silcd/command.c.
1916 * Fixed LIST command (hopefully) to send correct reply
1917 packets. Affected file silcd/command.c.
1919 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1921 * The silc_packet_receive_process now returns FALSE if the
1922 read data was invalid packet, and TRUE if it was ok.
1924 The server now checks that if unauthenticated connection
1925 sends data and its processing fails the server will close
1926 the connection since it could be a malicious flooder.
1928 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1930 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1932 * Make sure the warning about error opening a log file is
1933 printed only once and not everytime it fails (produces
1934 too much useless log). Affected file lib/silcutil/silclog.c.
1936 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1938 * Made the silc_server_daemonise() function more readable.
1939 Affected file silcd/server.c.
1941 * Pid file is now optional, the user may comment it out from
1942 the config file. Removed define SILC_SERVER_PID_FILE, we
1943 don't need a default any longer. Affected file
1944 configure.in.pre, lib/Makefile.am.pre.
1946 * Make some use of the pid file. The server now dies at startup
1947 if it detects a valid pid file on his path. The server would
1948 die anyway in this circumstance, because of the bind() failure.
1949 Affected file silcd/silcd.c.
1951 * No longer compiling lib/dotconf.
1953 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1955 * Fixed JOIN command parsing not to crash. Affected file
1956 lib/silcclient/command.c.
1958 * Fied the NICK_CHANGE notify to add the new client entry
1959 even it is resolved. This removes an <[unknown]> nick
1960 thingy bug in the client. Affected file is
1961 lib/silcclient/client_notify.c.
1963 * Do not try to allocate 0 bytes (efence does not like it)
1964 in lib/silccore/silccomand.c when encoding payload.
1966 * Do not take IRCNICK as nickname in Irssi SILC client since
1967 it is not possible to set nickname before hand connecting
1968 the server (TODO has an entry about adding auto-nicking
1971 * Changed the silc_server_command_pending to check whether
1972 there already exists an pending entry with the specified
1973 command, command identifier and pending callback. This is
1974 to fix IDENTIFY and WHOIS related crashes that may register
1975 multiple pending commands with same identifier. Affected
1976 file silcd/command.c.
1978 * Fixed the server to reconnect to the router even if it
1979 was already reconnecting and EOF was received. This to
1980 fix a possibility that the server wouldn't ever try to
1981 auto-reconnect to the router. Affected file silcd/server.c.
1983 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1985 * Fixed the server's password authentication to use the
1986 length of the locally saved password, and not the one
1987 sent in the packet. Affected file silcd/protocol.c.
1989 * Fixed same password authentication problem in the
1990 Authentication Payload handling routines in
1991 lib/silccore/silcauth.c.
1993 * Yet another password authentication problem fixed with
1994 channel password handling in silcd/command.c.
1996 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1998 * If first character of string in silc_parse_userfqdn is '@'
1999 then do not parse it. Affected file is
2000 lib/silcutil/silcutil.c.
2002 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2004 * Fixed minor bug in IDENTIFY command reply sending, which
2005 caused various weird problems during JOIN when it was
2006 resolving names for users. Affected file silcd/command.c.
2008 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2010 * Fixed the IDENTIFY command reply sending to chech better valid
2011 clients. It was possible to send incomplete list of replies.
2012 Affected file silcd/command.c.
2014 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2016 * Added silc_client_command[s]_[un]register functions now to
2017 dynamically register the commands in client library. Removed
2018 the static table of commands. This allows the client library
2019 to call commands without causing the application to know about
2020 what commands library has called.
2022 Removed the INFO command reply kludge to detect when the command
2023 was called by library. Now library use its own command reply
2024 function for INFO command.
2026 Added function silc_client_command_call to call a command.
2027 Application can use it to call command, not access the structure
2030 Now all commands that are sent by the client library (not
2031 explicitly sent by application) use own command reply functions.
2033 Affected files around lib/silcclient/ and in
2034 irssi/src/silc/core/.
2036 * Fixed the WHOIS command reply sending to chech better valid
2037 clients. It was possible to send incomplete list of replies.
2039 Fixed the WHOIS and IDENTIFY to send the request to router
2040 if normal server did not do it and did not find any results.
2042 Affected file silcd/command.c.
2044 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2046 * Moved the internal data from SilcClient context into its
2047 own file, not accesible to application. Affected files
2048 lib/silcclient/client.h and lib/silcclient/client_internal.h,
2049 and other files in client library.
2051 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2053 * Added doc/examples installation target in Makefile.am.pre.
2056 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2058 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
2059 commands the found client entry will be removed from the
2060 cache, after notifying application about the error. Affected
2061 file lib/silcclient/command_reply.c.
2063 * Changed the /MSG to check for exact nickname user gave, and
2064 not let `nick' match `nick@host' if it is only one found. Now,
2065 user must type the exact nickname (like nick@host2) even if
2066 there are no more than one same nicks found. This is to avoid
2067 a possibility of sending nickname to wrong nickname since
2068 `nick' could match `nick@host'. Affected file is
2069 irssi/src/core/silc-servers.c.
2071 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2073 * Do not print "you are now server operator" or similar when
2074 giving /away command. Affected files are
2075 irssi/src/silc/core/client_ops.c, silc-servers.h.
2077 * Made the silc_server_command_pending_error_check to send
2078 the same command reply payload it received back to the
2079 original sender of the command. This way all arguments
2080 that was received by the server will be received by the
2081 client too. Affected file silcd/command.c.
2083 * Added the silc_idcache_add to return the created cache entry
2084 to a pointer. Affected file lib/silccore/silcidcache.[ch].
2086 * Add global clients to expire if they are not on any channel.
2087 This is because normal server will never know if they signoff
2088 if they are not on any channel. The cache expiry will take
2089 case of these entries. This is done by normal servers only.
2090 The affected files are silcd/command_reply.c,
2091 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
2093 * If server receives invalid ID notification for WHOIS or
2094 IDENTIFY and the ID exists in the lists, it is removed.
2095 Affected file silcd/command_reply.c.
2097 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
2098 in client then client entry that it matches is searched and
2099 the nickname is printed on the screen for user. Affected
2100 file irssi/src/silc/core/client_ops.c.
2102 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2104 * Use cache entry expire time in the LIST command reply to
2105 purge old entries from the cache after the LIST command
2106 reply has been received. This way we don't have non-existent
2107 entries in the cache for too long. Affected file is
2108 silcd/command_reply.c.
2110 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2112 * If we are normal server, and we've not resolved client info
2113 in WHOIS or IDENTIFY from router, and it is global client,
2114 we'll check whether it is on some channel. If it is not
2115 then we cannot be sure about its validity and will resolve it
2116 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
2117 file silcd/command.c.
2119 * Search channel by name (if possible) rather than by ID
2120 in IDENTIFY command's command reply. Affected file is
2121 silcd/command_reply.c.
2123 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2125 * Distribute to the channel passphrase in CMODE_CHANGE notify.
2126 Updated specs and implemented it. Affected file silcd/command.c,
2127 silcd/packet_send.c and silcd/packet_receive.c.
2129 * Implemented the <founder auth> payload handling in the JOIN
2130 command. If provided all conditions for channel joining
2131 except requirement to provide correct passphrase can be
2132 overrided by the channel founder. Updated the protocol specs.
2133 Affected file silcd/command.c.
2135 Added support for founder auth in JOIN command in client
2136 library. Fixed the parsing of the JOIN command now to support
2137 all options as they should be. The affected file is
2138 lib/silcclient/command.c.
2140 * Optimized the WHOIS and IDENTIFY commands to send the request
2141 to router only if it includes nicknames or other names. If
2142 they include only IDs then check the local cache first before
2143 routing. Affected file is silcd/command.c.
2145 * Added channels topic announcements. Affected file is
2146 silcd/packet_receive.c and silcd/server.c.
2148 * Fixed the silc_server_send_notify_topic_set to really destine
2149 the packet to channel. Affected file silcd/packet_send.c.
2151 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
2152 library. Affected file lib/silcclient/client_notify.c.
2154 * Added UMODE announcements. Affected file silcd/server.c.
2156 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2158 * Memory leak fixes in:
2160 lib/silcutil/silcsockconn.c
2161 lib/silcske/silcske.c
2162 lib/silcske/groups.c
2164 lib/silccrypt/silcpkcs.c
2165 lib/silccore/silccommand.c
2166 lib/silccore/silcidcache.c
2171 * ROBOdoc documented the lib/silcske/groups.h file and a
2172 bit changed the interface for better.
2174 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2176 * Update the client entry context in the ID cache after
2177 nick change. Affected file lib/silcclient/command.c.
2178 Fixes the CUMODE command when regaining founder privileges,
2179 and a little WHOIS problem.
2181 * Fixed silc_net_gethostbyname to correctly call the
2182 inet_ntop. Affected file lib/silcutil/silcnet.c.
2184 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2186 * Added IPv6 support checking to the configure.in.pre, added
2187 also --enable-ipv6 option to override the check. Affected
2188 file configure.in.pre.
2190 * The silc_thread_create now calls the start function
2191 directly if threads support is not compiled in. Removes
2192 ugly #ifdef's from generic code. Affected files are
2193 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
2195 * Added silc_net_gethostby[name/addr]_async to asynchronously
2196 resolve. Affected files are lib/silcutil/silcnet.[ch].
2198 * Added support for rendering IPv6 based server, client and
2199 channel IDs. Affected file lib/silcutil/silcutil.c.
2201 * Added support for creating IPv6 based server IDs. Affected
2202 file is silcd/serverid.c.
2204 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2206 * Added silc_net_gethostby[addr/name] into the
2207 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
2208 routines. Added silc_net_is_ip[4/6]. Affected file is
2209 lib/silcutil/unix/silcunixnet.c. All routines that take
2210 address as argument now supports both IPv4 and IPv6 addresses.
2212 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2214 * Fixed LIST command reply sending in server. Affected file
2217 * Server now sends the kicker's client ID in the KICK notify
2218 to the kicked client. Affected file silcd/command.c.
2220 * The client library now parses the kickers client ID and
2221 UI displays it. Affected files lib/silcclient/client_notify.c
2222 and irssi/src/silc/core/silc-channels.c, module-formats.c.
2224 * Made all payload parsing function prototypes consistent.
2225 They all take now const unsigned char * and uint32 pair as
2226 the payload data instead of SilcBuffer. Changes all around
2227 the source tree. Other unsigned char* -> const unsigned char*
2228 changes around the tree as well.
2230 * Optimized SFTP client and server packet sending not to
2231 allocate new buffer for each packet but to recycle the
2232 first allocated buffer. Affected files are
2233 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
2235 * Optimized the SFTP client to use SilcList instead of
2236 SilcDList for requests, because it is faster. Affected file
2237 is lib/silcsftp/sftp_client.c.
2239 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
2240 into lib/silccore/silcid.[ch].
2242 Renamed silcpayload.[ch] into silcargument.[ch].
2244 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2246 * If client entry is deleted with active key agreement
2247 session, abort the session.
2249 The silc_client_abort_key_agreement now calls the completion
2250 callback with new SILC_KEY_AGREEMENT_ABORTED status.
2252 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
2255 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2257 * Don't use __restrict in older GCC's. Affected file is
2258 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
2260 * silc_net_localhost now attempts to reverse lookup the
2261 IP/hostname. Affected file lib/silcutil/silcnet.c.
2263 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
2264 command. It can be used to gain founder privileges at
2265 the same time when joining the channel.
2267 Defined that the SILC_NOTIFY_TYPE_KICKED send the
2268 kicker's client ID as well. Updated protocol specs.
2270 Defined that the server must send SILC_COMMAND_IDENTIFY
2271 command reply with error status to client who sent
2272 private message with invalid client ID.
2274 Updated the protocol specification.
2276 * Added silc_server_send_command_reply to send any
2277 command reply. Affected file silcd/packet_send.[ch].
2279 * Added silc_id_payload_encode_data to encode ID payload
2280 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
2282 * The server now send IDENTIFY command reply with error
2283 status if client ID in private message is invalid. Affected
2284 file silcd/packet_receive.c.
2286 * Save the server key file with server's IP address in
2287 the filename instead of hostname. The affected file is
2288 irssi/src/silc/core/client_ops.c.
2290 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2292 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
2295 * Added libtool support for compiling shared objects in
2296 lib/silcsim. Affected file configure.in.pre and
2297 lib/silcsim/Makefile.am. Original patch by cras.
2299 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2301 * Pid file configuration, and server's config file fixes
2302 patch by toma. Updated CREDITS file.
2304 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2306 * Fixed silc_client_channel_message to not try to decrypt
2307 the message twice if it resolved the destination client
2308 information. This could cause of dropping one channel
2309 message. Affected file lib/silcclient/client_channel.c.
2311 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2313 * Added silc_client_run_one into lib/silcclient/silcapi.h and
2314 lib/silcclient/client.c. This function is used when the SILC
2315 Client is run under some other scheduler, or event loop or
2316 main loop. On GUI applications, for example this may be
2317 desired to used to run the client under the GUI application's
2318 main loop. Typically the GUI application would register an
2319 idle task that calls this function multiple times in a second
2320 to quickly process the SILC specific data.
2322 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2324 * Fixed silc_server_drop() for dropping the supplementary
2325 groups as well, this could cause a security hole on some
2328 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2330 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
2333 * Write PID file after dropping privileges. Added -F option
2334 to run server on foreground. A patch by debolaz.
2335 Affected files silcd/server.c, silcd/silcd.c.
2337 * Fixed MOTD to return the MOTD file server name. Affected
2338 file silcd/command.c.
2340 * Added INFO command reply handling to the Irssi SILC Client.
2341 Affected file irssi/src/silc/core/client_ops.c.
2343 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2345 * Fixed the silc_idcache_list_* routines to really support
2346 the dynamic list. Fixes a crash. Affected file is
2347 lib/silccore/silcidcache.c.
2349 * Fixed the LIST command reply to really call LIST command's
2350 pending callbacks. Affected file silcd/command_reply.c.
2352 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2354 * Update conn->local_entry->nickname after giving NICK
2355 command. Affected file lib/silcclient/command.c.
2357 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
2359 * Added the [pid] option to the silcd configuration file
2361 Affected files: serverconfig.[ch] and silcd.c
2363 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2365 * Save fingerprint in WHOIS command reply in server.
2366 Affected file silcd/command_reply.c.
2368 * Fixed NICK commands pending callback registration.
2369 Affected file lib/silcclient/command.c.
2371 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2373 * Use ++server->cmd_ident when sending commands in server,
2374 instead of random number. Affected file silcd/command.c.
2376 * Fixed GETKEY command reply to call actually GETKEY pending
2377 command callbacks. Affected file silcd/command_reply.c.
2379 * A bit stricter check for nicknames. Check for same nickname
2380 in NICK command also. Affected file silcd/command.c.
2382 * Do not call INFO command everytime client ID changes, only
2383 during first connecting. Affected file lib/silcclient/client.c.
2385 * Set the new nickname only after successful command reply for
2386 NICK command is returned by server. Affected file
2387 lib/silcclient/command.c.
2389 * Remove nicknames from nicklist during server_signoff notify.
2390 Should fix /NAMES bit more. The affected file is
2391 irssi/src/silc/core/silc-channels.c.
2393 * Added `fingerprint' field to the SilcIDListData in the
2394 silcd/idlist.h to hold the fingerprint of the client's
2397 Send the fingerprint of the client's public key in WHOIS
2400 Affected files silcd/command.c, and silcd/idlist.[ch].
2402 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
2403 create fingerprint from given data.
2405 * Show the fingerprint of the client's public key in WHOIS.
2406 Affected files irssi/src/module-formats.[ch] and
2407 irssi/src/silc/core/client_ops.c.
2409 * Format the multiple same nicknames also during JOIN and
2410 NICK_CHANGE notifys. Affected file is
2411 lib/silcclient/client_notify.c.
2413 * Do not print error on screen for invalid private message
2414 payload since it can come if someone is sending private
2415 messages with wrong key. Affected file
2416 lib/silccore/silcprivate.c.
2418 * Fixed multiple concurrent /PING crash. Affected file
2419 lib/silcclient/command.c.
2421 * Changed the wrong ID encoding. All IP addresses must be
2422 in MSB first order in encoded format. They were encoded
2423 wrong and was in LSB format. Affected files are
2424 silcd/serverid.c, lib/silcutil/silcutil.c.
2426 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
2428 * Call the `connect' client operation through the scheduler
2429 in case of error. Affected file lib/silcclient/client.c.
2431 * Call the `failure' client operation even if the error
2432 occurred locally during a protocol. Affected file is
2433 lib/silcclient/protocol.c.
2435 * Added support of sending LIST command to router from normal
2436 server. This way normal server can get list of all channels
2437 in the network too. Fixed the channel list sending in the
2438 server too. Affected files are silcd/command.c, and
2439 silcd/command_reply.[ch].
2441 * Added silc_server_update_channels_by_server and
2442 silc_server_remove_channels_by_server. They are used during
2443 disconnection of primary router and in backup router protocol.
2444 Affected file silcd/server_util.[ch], silcd/server.c and
2445 silcd/server_backup.c.
2447 * Fixed channel adding to global list in IDENTIFY command
2448 reply in server. Affected file silcd/command_reply.c.
2450 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2452 * If the incoming packet type is REKEY or REKEY_DONE process
2453 that packet always synchronously. Fixes yet another MAC
2454 failed error on slow (dialup) connections. Affected file
2455 lib/silcclient/client.c and silcd/server.c.
2457 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2459 * Call check_version SKE callback for initiator too. Affected
2460 file lib/silcske/silcske.c.
2462 * Implemented fix for security hole found in the SKE that was
2463 fixed in the specification few days back; the initiator's
2464 public key is now added to the HASH value computation.
2465 Added backwards support for the old way of doing it too, for
2466 old clients and old servers. Affected file is
2467 lib/silcske/silcske.c.
2469 * Enabled mutual authentication by default in SKE. If initiator
2470 is not providing mutual authentication the responder will
2471 force it. This will provide the proof of posession of the
2472 private key for responder. The affected files are
2473 lib/silcclient/protocol.c and silcd/protocol.c.
2475 * Do not cache anymore the server's public key during SKE.
2476 We do mutual authentication so the proof of posession of
2477 private key is done, and if the server is authenticated in
2478 conn auth protocol with public key we must have the public
2479 key already. Affected file silcd/protocol.c.
2481 * Added new global debug variable: silc_debug_hexdump. If
2482 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
2483 file lib/silcutil/silclog.[ch].
2485 * Fixed compilation warning due to char * -> const char *.
2486 Affected files lib/silcutil/silcnet.h, and
2487 lib/silccore/silcauth.[ch].
2489 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2491 * Fixed CMODE command when new channel key was created. If
2492 the creation failed the old key was removed. Next time giving
2493 same command would crash the server since the old key was
2494 freed already. Affected file silcd/command.c.
2496 * Fixed the silc_server_announce_get_channels to not crash
2497 on reconnect. Affected file silcd/server.c.
2499 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2501 * Added silc_log_set_debug_string function to set a regex
2502 string to match for debug output. Only the function names,
2503 or filenames matching the given debug string is actually
2504 printed. This way it is possible to filter out those debug
2505 strings that user is not interested in.
2507 Fixed a bug in silc_string_regexify.
2509 Affected files lib/silcutil/silclog.[ch], and
2510 lib/silcutil/unix/silcunixutil.c.
2512 * Changed the -d options in both server and Irssi SILC client
2513 to take the debug string as argument. Affected files
2514 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
2516 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2518 * Added silc_hash_babbleprint to create a Bubble Babble
2519 Encoded fingerprint. The encoding is developed by Antti
2520 Huima (draft-huima-babble-01.txt), and it creates human
2521 readable strings out of binary data. Affected file
2522 lib/silccrypt/silchash.[ch].
2524 * Print the babble print now in addition of fingerprint as well
2525 in Irssi SILC client. Affected files are
2526 irssi/src/fe-common/silc/module-formats.[ch],
2527 irssi/src/fe-common/silc/core/client_ops.c.
2529 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2531 * Fixed a security problem found in SKE. The initiator's
2532 public key too is now added to the HASH hash value creation
2533 which is signed by the responder to create the SIGN value.
2534 This will prevent anyone in the middle to lie to the responder
2535 about the initiator's public key. If this is done now, the
2536 man in the middle will get caught. Updated the protocol
2539 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2541 * Better installation directory handling. Configure module
2542 paths and other paths automatically to example_silc* files
2543 in doc/. A patch by toma.
2545 * Fixed compiler warning from MPI library, and from SILC RNG.
2548 * Added SILC_SERVER_PID_FILE to define the pid file for server.
2549 It can be configured with ./configure. A patch by toma.
2551 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2553 * Find correct make to use in prepare-clean. A patch by
2554 toma. Affected file prepare-clean.
2556 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
2558 * Added irssi variables use_auto_addr, auto_bind_ip,
2559 auto_bind_port and auto_public_ip.
2561 * Changed the interface for silc_client_send_key_agreement
2562 in lib/silcclient/silcapi.h
2566 irssi/src/silc/core/silc-core.c
2568 lib/silcclient/silcapi.h
2569 irssi/src/silc/core/silc-channels.c
2570 lib/silcclient/client_keyagr.c
2573 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2575 * Added silc_pkcs_public_key_compare to compare two
2576 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
2578 * Check that the client who set the founder mode on the
2579 channel is the same client that is giving the founder
2580 mode to itself. It is done by comparing the saved public
2581 key (it is saved even in the authentication is passphrase).
2582 Affected file silcd/command.c.
2584 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2586 * Do not process packet for disconnected socket connection.
2587 Affected file lib/silccore/silcpacket.c.
2589 * Process the DISCONNECT packet through scheduler in the
2590 client library. Affected file lib/silcclient/client.c.
2592 * Fixed the silc_client_packet_parse to not to increase
2593 the packet sequence number if the conn->sock and the
2594 current socket connection is not same. This can happen
2595 for example during key agreement when the conn includes
2596 multiple socket connections (listeners). Affected file
2597 lib/silcclient/client.c.
2599 * The sender of the file transfer request now provides also
2600 the pointer (listener) for the key exchange protocol. If
2601 the listener cannot be created then it sends empty key
2602 agreement and lets the receiver provide the listener.
2604 Added `local_ip' and `local_port' arguments to the
2605 silc_client_file_send. If they are provided they are used,
2606 if not then it will attempt to find local IP address, if
2607 not found or bind fails then the remote client will provide
2610 Affected files are lib/silcclient/client_ftp.c and
2611 lib/silcclient/silcapi.h.
2613 * Extended the FILE SEND command to support defining the
2614 local IP and port for key exchange listener. They are
2615 optional. Affected file irssi/src/silc/core/silc-servers.c.
2617 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2619 * Defined to WHOIS command reply the sending of fingerprint
2620 of the client's public key (if the proof of posession of the
2621 corresponding private key is verified by the server).
2622 Updated to the protocol specification.
2624 * Added support of receiving the client's public key's
2625 fingerprint in command reply in client library. Affected
2626 file is lib/silcclient/command_reply.c, and
2627 lib/silcclient/idlist.[ch].

2686 preserve the WHOWAS info for the client. Affected file
2687 silcd/server_util.c.
2689 * Fixed SERVER_SIGNOFF notify handling in the server. The
2690 server is now able to process incoming SERVER_SIGNOFF notify
2691 for a server that it doesn't even know about. It will remove
2692 the clients provided in the notify. Affected file
2693 silcd/packet_receive.c.
2695 * Check for partial packet in data queue after every packet that
2696 was found from the queue. Return and wait for more data if
2697 there is partial data in queue. Affected file is
2698 lib/silccore/silcpacket.c.
2700 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>

2715 irssi/src/fe-common/silc/module-formats.[ch].
2717 * Wrote a help file for FILE command.
2719 * Added silc_rng_global_get_byte_fast to get not-so-secure
2720 random data as fast as possible. Random data is read from
2721 /dev/urandom if available and from the SILC RNG if not
2722 available. It is used in padding generation. Affected file
2723 lib/silccrypt/silcrng.[ch].
2725 * All packets in client library are now processed synchronously.
2726 Optimized packet processing a lot. Affected file
2727 lib/silcclient/client.c.

2738 * Assure that silc_client_notify_by_server_resolve does not
2739 resolve the client information multiple times. If it cannot
2740 be found by the first it cannot be found at all. Affected
2741 file lib/silcclient/client_notify.c.
2743 * Fixed WHOWAS command reply calling. Affected file
2744 lib/silcclient/command_reply.c.
2746 * Removed all references to silc_idlist_get_client from the
2747 Irssi SILC client since that call is internal call used by
2748 the library. The Irssi SILC client will use now client
2749 retrieval functions found in silcapi.h.
2751 * Fixed a bug in resolving nickname info before sending
2752 private message. It used freed memory. Affected file
2753 irssi/src/silc/core/silc-servers.c.
2755 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2757 * Assure my_channels statistics cannot go negative in server.
2758 Affected files silcd/server.c, silcd/server_util.c.

2774 * Added silc_net_localip to return local host's IP address.
2775 Affected file lib/silcutil/silcnet.[ch].
2777 * If key exchange or rekey protocol is active for a connection
2778 parse all packets syncronously since there might be packets
2779 in packet queue that we are not able to process without first
2780 processing packets before them. Affected file silcd/server,
2781 lib/silcclient/client.c.
2783 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2784 whether library should continue processing the packet.
2785 Affected file lib/silccore/silcpacket.h.

2831 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
2832 is incomplete and is being resolved, it won't be resolved
2835 Make sure also that USERS command reply does not resolve
2836 twice information. Affected file is
2837 lib/silcclient/command_reply.c.
2839 Make sure that silc_client_get_clients_by_list does not
2840 resolve twice same information.
2842 * Check for valid client->id in the silc_server_free_client_data.
2843 Affected file silcd/server.c.
2845 * Fixed /GETKEY nick@server not to crash if the server entry
2846 is not found. Affected file lib/silcclient/command.c.
2848 * Fixed the silc_server_check_cmode_rights to check the
2849 requested modes correctly. Affected file silcd/command.c.

2854 Affected file silcd/command.c.
2856 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2858 * Call the silc_server_udpate_servers_by_server in the
2859 primary router that comes back online in the backup resuming
2860 protocol. Otherwise it routes packets wrong. Affected file
2861 silcd/server_util.[ch], silcd/server_backup.c.
2863 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2865 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2866 lib/silcutil/silcbuffmt.[ch].
2868 * Redefined the SILC packet header to include the padding
2869 length. Affected file lib/silccore/silcpacket.[ch].
2871 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2872 length for maximum padding up to 128 bytes). Affected
2873 file lib/silccore/silcpacket.h.
2875 * Removed all backwards support for old 0.5.x MAC thingies.
2876 The SILC packet header change makes it impossible to be
2877 backwards compatible.
2879 * Send the ENDING packet with timeout in the backup resuming
2880 protocol. This is to assure that all routers has connected
2881 to the primary router. Affected file silcd/server_backup.c.
2883 * Changed the RNG to take the first IV from random data. It
2884 used to take it from zero actually. Changed the RNG also
2885 to use /dev/urandom during session. /dev/random is used
2886 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2888 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2890 * Changed the SILC packet header to have the first two bytes
2891 (the packet length) encrypted. Affected files aroung the
2892 code tree, lib/silccore/silcpacket.[ch]. Removed the
2893 SilcPacketCheckDecrypt callback. It is not needed anymore
2894 since the silc_packet_receive_process will determine now
2895 whether the packet is normal or special.
2897 * Implemented the unidirectional MAC keys. Affected files
2898 lib/silcske/silcske.c, silcd/protocol.c and
2899 lib/silcclient/protocol.c.
2901 * Implemented the packet sequence number to the MAC computation.
2902 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
2903 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
2904 lib/silcclient/protocol.c.
2906 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2908 * Allow backup router to announce servers. All servers
2909 announced by backup router are added to the global list
2910 automatically. Update hte server's socket to our primary
2911 router also when backup router announces a server.
2912 Affected file silcd/packet_receive.c.
2914 * Do not update the client->router in the function
2915 silc_server_udpate_clients_by_server if the client is on
2916 global list. We might fail to find any specific server
2917 for locally connected clients and local cell clients. They
2918 should still use the `from' and not `to' as client->router.
2919 This fixes backup router resuming protocol. Affected file
2920 silcd/server_util.c.
2922 * Decrease channel statistics count only if the channel
2923 deletion worked. Affected files are silcd/server.c and
2924 silcd/server_util.c.
2926 * Added silc_server_update_servers_by_server to update origin
2927 of all server entries. Used during backup router protocol.
2928 Affected files silcd/server_util.[ch], silcd/server.c. and
2929 silcd/backup_router.c.
2931 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
2932 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
2933 silc_hmac_get_hash and silc_hmac_get_name. Affected file
2934 lib/silccrypt/silchmac.c.
2936 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2938 * Assure that router cannot reroute the same channel message
2939 to the sender. Affected file silcd/packet_receive.c.
2941 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2943 * Made better checks that the channel message is not sent
2944 to the router it came from. Affected file is
2945 silcd/packet_send.c. Fixed memory leak too.
2947 * Announce informations for incoming router connection, but
2948 only after checking if it is replaced by backup router.
2949 Affected file silcd/packet_receive.c.
2951 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2953 * Fixed the backup resuming protocol to work in multiple
2954 router environment. Affected file silcd/server_backup.c.
2956 * Route packet only to one router in the function
2957 silc_server_packet_send_to_channel. Affected file is
2958 silcd/packet_send.c.
2960 * Fixed silc_server_send_notify_dest to set the broadcast
2961 flag. Fixed the silc_server_send_notify_topic to actually
2962 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2963 Affected file silcd/packet_send.c.
2965 * Changed the SFTP Filesystem interface. Changed the
2966 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2967 the filesystem operation function. The SilcSFTPFilesystem
2968 is now a context that is allocated by all filesystem allocation
2969 functions and it already includes the operations structure
2970 and filesystem specific context. It is given as argument
2971 now to the silc_sftp_server_start. This made the interface
2972 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2973 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2975 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2977 * Changed the backup router adding and getting interfaces
2978 in the server. The router that will be replaced by the
2979 specified backup router is now sent as argument. Affected
2980 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2983 * Added silc_net_addr2bin_ne to return the binary form of
2984 the IP address in network byte order. Affected files
2985 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
2987 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2989 * Check for existing server ID in silc_server_new_server
2990 and in silc_server_connect_to_router_final and remove the
2991 old entry if it exists. Affected file silcd/packet_receive.c,
2994 * Send the channel message always to only one router, either
2995 in upstream or downstream. Affected file is
2996 silcd/packet_send.c.
2998 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3000 * Wrote the definition of the backup resuming protocol to the
3001 protocol specification.
3003 * Removed one redundant channel key generation from normal
3004 server during joining procedure. Removed one redundant
3005 channel key sending from server to router during joining
3006 procedure. Affected file silcd/command.c.
3008 * Made minor bugfixes to the backup router resuming protocol.
3009 Affected file silcd/server_backup.c, server.c.
3011 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3013 * Added --disable-asm configuration option. Affected files
3014 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
3017 * Implemented the backup resuming protocol that is used to
3018 resume the primary router position in the cell after the
3019 primary router comes back online. Affected files
3020 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
3021 and silcd/server_util.[ch].
3023 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3025 * Sleep two (2) seconds after sending QUIT command to server.
3026 Affected file lib/silcclient/command.c.
3028 * Assure that if outgoing data buffer is pending do not force
3029 send any data. Affected file silcd/packet_send.c.
3031 * Assure that if outgoing data buffer is pending do not force
3032 send any data. Affected file lib/silcclient/client.c.
3034 * Implemented the backup router support when the primary router
3035 goes down. The servers and routers can now use the backup
3036 router as new primary router without loosing connectivity.
3038 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3040 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
3041 in the server to indicate disabled entry. All data read
3042 from the connection will be ignored and no data is sent
3043 for entry that is disabled. Affected files are
3044 silcd/idlist.h, silcd/server.c.
3046 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3048 * Created SFTP client and server test programs in the
3049 lib/silcsftp/tests directory.
3051 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3053 * Implemented memory filesystem (virtual filesystem) for
3054 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
3057 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3059 * Implemented the SFTP (SSH File Transfer Protocol) to the
3060 lib/silcsftp. It includes SFTP client and SFTP server
3063 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3065 * Moved lib/silccore/silcprotocol.[ch] to the
3066 lib/silcutil library.
3068 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
3069 take variable argument list pointer as argument. Affected
3070 file lib/silcutil/silcbuffmt.[ch].
3072 * Added silc_buffer_set function that is used to set data
3073 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
3074 Affected file lib/silcutil/silcbuffer.h.
3076 * Changed various routines in the core library to use the new
3077 silc_buffer_set instead of allocating new buffer only for
3080 * Added 64-bit value formatting and unformatting support to the
3081 silc_buffer_[un]format routines. Affected file is
3082 lib/silcutil/silcbuffmt.[ch].
3084 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
3085 to includes/bitmove.h.
3087 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3089 * Fixed channel user mode saving in client library. Affected
3090 file lib/silcclient/command[_reply].c.
3092 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3094 * Defined the file transfer to the SILC Protocol. Added
3095 new packet type SILC_PACKET_FTP and defined File Transfer
3096 Payload. The mandatory file transfer protocol is SFTP
3097 (SSH File Transfer Protocol). Affected file in addition
3098 of the internet draft is lib/silccore/silcpacket.h.
3100 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
3101 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
3102 is used as part of backup router protocol when the primary
3103 router of the cell is back online and wishes to resume
3104 the position as primary router.
3106 * Redefined the MAC generation keys in the protocol. The
3107 same key is not used anymore in both direction. Both
3108 direction will now use different keys for sending and
3109 receiving. This fixes a potential security flaw. This
3110 change causes incompatibilities in the protocol.
3112 * Redefined also the MAC computation from the packet.
3113 An packet sequence number is now added to the MAC
3114 computation. This prevents possible replay attacks against
3115 the protocol. This change too causes incompatibilities
3118 Added `sequence' field to the SilcPacketContext to hold
3119 the current sequence number for the packet.
3121 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3123 * Added `created' field to the SilcIDListData in the file
3124 silcd/idlist.h to indicate the time when the entry was
3127 * Added `created' field to the SilcChannelEntry too. Affected
3128 file silcd/idlist.h.
3130 * Added `creation_time' aguments to all the announcement functions
3131 in the server. If it is provided then only the entries that
3132 was created after the provided time frame are actually
3133 announced. Affected file silcd/server.[ch].
3135 * The protocol says that the Channel ID's IP address must be
3136 based on the router's IP address. Added check for this in
3137 the silc_server_new_channel when processing incoming New Channel
3138 Payload. Affected file silcd/packet_receive.c.
3140 * Print out the correct version with --version in SILC client.
3141 Affected file irssi/src/silc/core/silc-core.c.
3143 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3145 * Fixed WHOWAS command to check for completnes of the client
3146 entry always, not just when the command is coming from client.
3147 Affected file silcd/command.c.
3149 * Added new function silc_server_packet_queue_purge to purge the
3150 outgoing data queue to the network. After the function returns
3151 it is guaranteed that the outgoing packet queue is empty.
3152 Affected file silcd/packet_send.[ch].
3154 * Purge the outgoing packet queue in the rekey protocol's final
3155 callback to assure that all rekey packets go to the network
3156 before quitting the protocol. Affected file silcd/server.c.
3158 * Added silc_client_packet_queue_parse as similar function as
3159 in server to the client library. The affected file is
3160 lib/silcclient/client.c.
3162 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3164 * Splitted silcd/server.c and created silcd/server_util.[ch]
3165 for utility functions.
3167 * Added new socket flag SILC_SF_DISABLED to indicate that the
3168 connection is open but nothing can be sent to or received from
3169 the connection. Affected file lib/silcutil/silsockconn.[ch].
3170 The checking for disabled socket is checked in the low level
3171 silc_socket_write and silc_socket_read functions.
3173 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3175 * Allow only nicknames and channel names that fits into the
3176 7-bit unsigned char ASCII set. Affected file silcd/command.c.
3178 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3180 * When processing JOIN command reply in server check that if
3181 the channel exists in our global list we'll move it the local
3182 list. Affected file silcd/command_reply.c.
3184 * Fixed the check whether client is joined on the channel already
3185 in JOIN command. Affected file lib/silcclient/command.c.
3187 * Fixed the JOIN command reply to check whether the channel
3188 already exists. Affected file lib/silcclient/command_reply.c.
3190 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3192 * Added silc_ske_status_string to map the SKE error numbers
3193 to readable strings. The affected files are
3194 lib/silcske/silcske[_status].[ch].
3196 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3198 * Do not show the private channels on the WHOIS channel list
3199 as it is not allowed by the protocol. The affected file is
3202 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3204 * Assure that the packet length digged from the actual packet
3205 is something sensible in the silc_packet_decrypt_rest_special
3206 in lib/silccrypt/silcpacket.c.
3208 * Free and NULL the allocated pointer in silc_hmac_alloc if
3209 the HMAC allocation fails. The affected file is
3210 lib/silccrypt/silchmac.c.
3212 * Print the selected security properties to the log files in
3213 the server. Affected file silcd/protocol.c.
3215 * Add SKE's reference counter even if calling the completion
3216 callback manually. Otherwise it goes negative, although it
3217 does not cause any problems. The affected file is
3218 lib/silcske/silcske.c.
3220 * Remove the client entry with short timeout after giving the
3221 KILL command. Affected file lib/silcclient/command.c.
3223 * Fixed to send error reply in WHOIS and IDENTIFY commands in
3224 case all found clients are already disconnected (WHOWAS would
3225 found them) in the server. Affected file silcd/command.c.
3227 * Update the last_receive (time of last data received) to be
3228 updated only when received private or channel message so that
3229 the idle time showed in WHOIS makes more sense.
3231 * Added boolean field `valid' in to the SilcClientEntry in the
3232 client library to indicate whether the entry is valid or not.
3233 This fixes the nickname change bug on channel when changing
3234 the nickname to be same than the old (like nick to Nick) the
3235 nickname formatter doesn't set the new nick anymore to Nick@host.
3236 Affected file lib/silcclient/idlist.[ch].
3238 * Now actually fixed the nickname changing on disconnection.
3239 Added new function silc_change_nick to the Irssi SILC Client.
3240 Affected file irssi/src/silc/core/client_ops.c,
3241 irssi/src/silc/core/silc-nicklist.[ch].
3243 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3245 * Check that the public key exists in the GETKEY command before
3246 trying to encode it. Affected file silcd/command.c.
3248 * Print some notifications on received public keys with GETKEY
3249 command in the Irssi SILC Client. Affected files are
3250 irssi/src/fe-common/silc/module-formats.[ch],
3251 irssi/src/silc/core/client_ops.c.
3253 * Use IDENTIFY command to resolve the server information in the
3254 GETKEY command instead of INFO command. Affected file
3255 lib/silcclient/command.c.
3257 * All command reply functions in the client library now calls
3258 the pending command reply callbacks even if an error has
3259 occurred. The server has done this a long time and now it was
3260 time to move the client library to this as well. Now all
3261 errors can be delivered back to the pending command reply
3262 callbacks if necessary. Affected files are
3263 lib/silcclient/command[_reply].[ch].
3265 * Change the nickname on disconnection back to the username
3266 because in reconnect the server will enforce it to it anyway.
3267 Affected file irssi/src/silc/core/silc-servers.c.
3269 * Fixed a config file parsing bug in the Irssi SILC client.
3270 Affected file irssi/src/silc/core/clientconfig.c.
3272 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3274 * When printing the channel mode on JOIN, verify that the
3275 channel key and channel's HMAC are valid. Affected file
3276 irssi/src/silc/core/client_ops.c.
3278 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3280 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
3281 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
3282 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
3284 * Removed channel key rekey task deleting from the function
3285 silc_server_save_channel_key. Affected file silcd/server.c.
3286 Added explicit timeout task context instead that is used to
3287 delete the task if we are registering a new task before the
3288 new task has elapsed.
3290 * When channel key rekey occurs the client library now saves
3291 the old channel key for a short period of time (10 seconds) and
3292 is able to use it in case some is still sending channel
3293 messages encrypted with the old key after the rekey. Affected
3294 file lib/silcclient/[idlist.h|client_channel.c].
3296 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3298 * Added check to the silc_server_new_id_real to not accept
3299 new ID if it is the sender's own ID. Affected file is
3300 silcd/packet_receive.c.
3302 * Assure that we do not announce ourself or the one we've
3303 sending our announcements when we're router and are announcing
3304 servers to our primary router. Affected file silcd/server.c.
3306 * Fixed silc_server_command_identify_check_client to assemble
3307 correct WHOIS packet. It send corrupted WHOIS packet and
3308 caused problem with router to router connections. Affected
3309 file silcd/command.c.
3311 Fixed also silc_server_command_whois_check the same way
3312 as for the IDENTIFY command.
3314 * Added new SilcIDListStatus to the server in the SilcIDListData
3315 structure. The status now includes the current status of
3316 the entry (like registered, resolved etc.). Affected file
3317 silcd/idlist.[ch]. Defined a bunch of different status types
3318 as well. This replaced the old boolean registered field as well.
3320 Added resolve_cmd_ident field to the SilcClientEntry structure
3321 too so that if the entry is for example being resolved so
3322 another command may attach to the same pending command reply
3323 without requiring to resolve the same entry again. This concept
3324 should optimize the WHOIS and the IDENTIFY resolving under
3325 heavy load by taking away unnecessary resolving for entries
3326 that are being resolved already.
3328 Added support for adding multiple pending commands for one
3329 command idenfier. Affected file silcd/command[_reply].[ch].
3331 * Fixed WHOIS and IDENTIFY save to remove the cache entry
3332 before deleting the data. Otherwise the hash table will have
3333 freed data in comparison functions. Affected file is
3334 silcd/command_reply.c.
3336 * Fixed silc_idlist_replace_client_id to add the new entry to
3337 the cache with NULL nickname. Otherwise there will be invalid
3338 memory as the nickname after the nickname is freed. Affected
3339 file silcd/packet_receive.c.
3341 * Fixed the silc_idlist_get_clients_by_hash. The entries was
3342 saved into wrong slots because the previous number of entries
3343 was not taken into account. Affected file silcd/idlist.c.
3344 Fixed same thing in silc_idlist_get_clients_by_nickname too.
3346 * If we are router and we receive JOIN notify to a channel that
3347 does not have any users then notified client is marked as the
3348 channel founder, as it is it. The affected file is
3349 silcd/packet_receive.c
3351 * Added to the extended hash table API's table_del_*ext functions
3352 the destructor as argument too, so that the caller can decide
3353 which destructor to use or whether to use destructor at all.
3354 Affected file lib/silcutil/silchashtable.[ch].
3356 * Fixed ID Cache purging. It actually deleted the entries from
3357 the hash table after the data was freed. The hash table ended
3358 up comparing freed memory. The affected file is
3359 lib/silccore/silcidcache.c.
3361 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3363 * Fixed Irssi SILC client's KILL command's HELP syntax.
3365 * The USERS command now resolves the detailed user information
3366 if the userinfo field is missing. Affected file is
3367 lib/silcclient/command_reply.c.
3369 * Do not print error in silc_file_read if the read file does
3370 not exist. Just silently return NULL. Affected file is
3371 lib/silcutil/silcutil.c.
3373 * Fixed the silc_log_output to not wine about NULL filename
3374 and to not create some bogus " " filename. Affected file is
3375 lib/silcutil/silclog.c.
3377 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3379 * Fixed various printing bugs on the user interface in the
3380 Irssi SILC Client. Minor changes that were forgotten from
3383 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3385 * Fixed the configure.in.pre and the compilation and distribution
3386 environment to support the new autoconf 2.52. That version is
3387 now required to compile the CVS trunk.
3389 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3391 * Renamed function silc_parse_nickname to silc_parse_userfqdn
3392 to generally parse user@fqdn format strings. Affected file
3393 lib/silcutil/silcutil.c.
3395 * Added nickname_format and nickname_force_format fields to the
3396 SilcClientParams structure. The first one defines the format
3397 for the nicknames that the library will enforce if the receives
3398 multiple same nicknames. The second one is boolean value and
3399 can be used to force the library to always enforce the format
3400 to the nicknames regardles whether there are multiple nicknames
3401 or not. This configurable formatting was employed to flexibly
3402 support accessing multiple nicknames from the user interface.
3403 The userinterface can now set the nicknames to what ever format
3404 they prefer. Affected file lib/silcclient/silcapi.h.
3406 Added function silc_client_nickname_format to the file
3407 lib/silcclient/idlist.c. It performs the nickname formatting.
3409 Added new field `hostname´ to the SilcClientEntry context.
3410 It holds the hostname of the client. Affected file is
3411 lib/silcclient/idlist.h.
3413 * Irssi SILC Client sets the nicknames in nick@hostn format.
3414 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
3415 irssi/src/silc/core/silc-core.c.
3417 The WHOIS printing now also shows both the real nickname and
3418 the formatted nickname so that user knows how to access the
3419 user if there are multiple same nicknames cached. Affected
3420 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
3421 printing formatting too to take the hostname now as a separate
3422 argument. The Affected file is
3423 irssi/src/fe-common/silc/modules-formats.[ch].
3425 * Changed the silc_client_get_clients_local to accept the formatted
3426 nickname as argument. It accepts the real nickname too but the
3427 formatted nickname can be used to find the true entry from
3428 multiple entries. Affected file lib/silcclient/silcapi.h and
3429 lib/silcclient/idlist.c.
3431 * Added nickname_format_parse field to the SilcClientParams.
3432 It is a callback function provided by the application to parse
3433 the nickname out of the formatted nickname string. The library
3434 calls it to get the nickname from the formatted string. Since
3435 the application generally knows better the format of the nickname
3436 string it parses it instead of the library, even though library
3437 encodes the formatted string. If the callback function is not
3438 provided then the library will use the string as is. The
3439 affected file is lib/silcclient/silcapi.h.
3441 * All the nickname strings passed to the client library in
3442 commands are now expected to be formatted nickname strings.
3443 If the command does not support the formatted nickname string
3444 it will assume that the sent string is the actual nickname.
3445 Affected file lib/silcclient/command.c.
3447 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3449 * Added public key authentication support to OPER and SILCOPER
3450 commands in the client library. Affected file is
3451 lib/silcclient/command.c.
3453 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3455 * Changed the get_auth_methdod client operation to be asynchronous.
3456 It can be async if the application resolves the authentication
3457 method from the server during the negotiation. Added new
3458 SilcGetAuthMeth completion callback that the application will
3459 call after resolving the authentication method.
3461 Added function silc_client_request_authentication_method that
3462 the application can use to resolve the authentication method
3463 from the server. Added also SilcConnectionAuthRequest callback
3464 that the library will call after the server has replied. The
3465 application can call this function if it does not know the
3466 current authentication method.
3468 Affected files are lib/silcclient/client.c and
3469 lib/silcclient/silcapi.h.
3471 * The Irssi SILC client now automatically resolves the authentication
3472 method incase any configuration information is not present (and
3473 currently there never is). The affected file is
3474 irssi/src/silc/core/client_ops.c.
3476 * Fixed public key authentication from the client library.
3477 Affected file lib/silcclient/protocol.c. Changed also the
3478 protocol specification about the public key authentication in
3479 the connection authentication protocol. The actual data to be
3480 signed is now computed with a hash function before signing.
3482 * Fixed the public key authentication from the server as well.
3483 Affected file silcd/protocol.c.
3485 * Removed the mlock()'s from the memory allocation routines.
3486 Affected file lib/silcutil/silcmemory.c. The ./configure does
3487 not check anymore for the mlock(). Affected file is
3490 * Fixed USERS command in server to allow the execution of the
3491 command for private and secret channels if the client sending
3492 the command is on the channel. Affected file silcd/command.c.
3494 * Fixed silc_client_get_clients_local to return the clients
3495 count correctly. It could return wrong value. Affected file
3496 lib/silcclient/idlist.c.
3498 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3500 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
3501 types. The assembler optimizations seemed not to like 64-bit
3502 data types. The assmebler optimizations thus are now enabled
3503 also for BSD systems as opposed to only enable them for Linux.
3505 * Do not check for threads at all on BSD systems. Affected
3506 file configure.in.pre.
3508 * Removed -n and -h options from the Irssi SILC Client since
3509 they are not used in silc.
3511 * Fixed the prime generation to assure that the first digit
3512 of the generated random number is not zero since our conversion
3513 routines does not like number strings that starts with zero
3514 digit. If zero digit is seen the random number is regenerated.
3515 This caused some corrupted RSA keys when the zero first digit
3516 was met. Affected file lib/silcmath/silcprimegen.c.
3518 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3520 * Fixed WIN32 configuration in the ./configure script.
3521 Fixed to include xti.h on environments that has it.
3522 Patches by Carsten Ilchmann and andrew.
3524 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3526 * Changed the silc_id_create_client_id to be collision
3527 resistant. It is now assured that there cannot be created
3528 two same client ID's. I suspect that some weird bugs in
3529 the server were actually caused by duplicate Client IDs.
3530 Affected file silcd/serverid.[ch]. A router receiving
3531 new ID now also assures and informs the sending server
3532 if the ID caused collision.
3534 * Changed the silc_id_create_channel_id to also assure that
3535 there are no collisions.
3537 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3539 * Statement about ignoring the Mutual Authentication flag when
3540 performing rekey with PFS was a bit misleading. It is ignored
3541 if it was set in the initial negotiation, it cannot be even
3542 set in the rekey. Fixed in the ke-auth draft. Started the
3543 new versions of the protocol drafts in the doc/.
3545 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3547 * Fixed a bug in silc_client_command_identify_save when saving
3548 new channel information. The channel name was no duplicated
3549 and caused crash on exit. Affected file is
3550 lib/silcclient/command_reply.c.
3552 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3554 * Fixed the getkey command handling in the server. Send just
3555 empty OK reply to the sender if the key could not be fetched
3556 (but everything else was ok, like the key just was not available).
3557 Changed the public key parameter to optional in the protocol
3558 specs so that empty OK reply can be sent. Affected file
3561 Added a message to Irssi SILC client to tell to user if the
3562 server did not return a public key.
3564 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3566 * Fixed a channel key regeneration bug. It registered new
3567 timeout tasks exponentially until all system resources were
3568 used. Affected file silcd/server.c.
3570 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3572 * Added the SILC Document generator to the scripts/silcdoc.
3573 It can be used to generate the Toolkit Reference Manual out
3574 of the source tree. Internally it will also use the RoboDoc
3575 generator now imported in util/robodoc.
3577 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3579 * Added couple of return's in rekey protocol if error orccurred
3580 during the protocol. The execution must be terminated.
3581 Affected file silcd/protocol.c. Also, terminate the protocol
3582 always with timeout.
3584 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3586 * The client's Client ID was created initally from the wrong
3587 nickname (it could have been in format nick@host) in the
3588 silc_server_new_client. Affected file silcd/packet_receive.c
3590 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3592 * Added some SILC_LOG_ERROR's to various error conditions
3593 if client could not be added to ID cache. Affected files
3594 silcd/packet_receive.c and silcd/server.c.
3596 * When client's sock->user_data is freed, NULL also the
3597 client->router and client->connection pointers. Added check
3598 for these pointers being NULL to various places around the
3599 code. Affected file silcd/server.c.
3601 * Added client->data.registered == TRUE checks to various
3602 places around the code to assure that unregistered client's
3603 are not handled when it is not allowed. Affected file
3606 * Added `bool registered' fields to all
3607 silc_idlist_[server|client]_get_* routines to indicate whether
3608 the fetched client needs to be registered or not. Affected
3609 file silcd/idlist.[ch].
3611 * Add your own entry as registered to the ID cache in the
3612 server. Affected file server.c.
3614 * Fixed a bug in silc_server_new_server. The SilcServer was
3615 set as the new server's context instead of SilcServerEntry.
3616 This naturally caused some weird bugs.
3618 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3620 * Do not delete the channel rekey task when adding it
3621 for in silc_server_create_channel_key.
3623 * Changed the silc_server_create_channel_key to return
3624 TRUE or FALSE to indicate the success of the channel key
3627 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3629 * Fixed MSVC++ project files and added missing files to
3630 Makefiles under win32/.
3632 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3634 * Do not add TCP_NODELAY flag if the operating system
3635 does not have it defined. Affected files are
3636 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3638 * Fixed buffer overflow from Irssi SILC Client. Affected
3639 file irssi/src/fe-common/core/themes.c.
3641 * Fixed double free in client library in the file
3642 lib/silcclient/client.c when disconnecting from server.
3644 * Applied double free patch from cras to Irssi SILC client.
3645 Affected files irssi/src/core/[modules/expandos].c
3647 * Fixed the disconnection handling to Irssi SILC Client.
3648 The application must call silc_client_close_connection
3649 in ops->connect client operation in case of failure of
3650 the connection. Affected file is
3651 irssi/src/silc/core/client_ops.c.
3653 * Do not set sock->protocol to NULL in the function
3654 silc_client_close_connection after executing the protocol's
3655 final callback since the sock might not be valid anymore.
3656 Affected file lib/silcclient/client.c.
3658 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3660 * Do not enable SILC_THREADS if the linking with libpthread
3661 did not happen. Affected file configure.in.pre.
3663 * Added notion to protocol specification that server must
3664 verify the sent authentication payload with CMODE when
3665 setting the channel founder key. Implemented it to the
3666 server. Affected file silcd/command.c.
3668 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3670 * Added _EXTRA_DIST SILC distribution variable to the
3671 distributions file. It is used to conditionally add extra
3672 files or directories to the specific distribution. Affected
3673 files ./prepare, Makefile.am.pre and distributions.
3675 Removed the `_' from the start of the distribution names.
3678 * Added README.WIN32 for instructions to compile the Toolkit
3681 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3683 * Fixed a double free in disconnection in the server. Affected
3684 file is silcd/server.c.
3686 * Fixed the lib/silcske/groups.c to work now also with GMP
3687 MP library. The string conversion did not work when using
3688 specific base and the base is indicated in the string as well.
3690 * Created win32/ directory which now includes MSVC++ specific
3691 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3692 It will appear only in the toolkit distribution
3694 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3696 * Changed the key material distribution function in case when
3697 the hash output is too short. The data is now concatenated
3698 a bit differently than it used to. Made the change to the
3699 SKE protocol specification.
3701 * Added better GMP detection to configure.in.pre. A patch
3704 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3706 * Fixed a minor bug in SKE that might cause some problem on
3707 some platforms. Affected file lib/silcske/silcske.c.
3709 * Added the cookie checking for initiator in the SKE. It checks
3710 that the responder returns the sent cookie unmodified. The
3711 affected file is lib/silcske/silcske.c. Added new SKE
3712 error type INVALID_COOKIE that can be sent during the
3713 negotiation. Fixed some memory leaks as well.
3715 * Added the "invalid cookie" error message to Irssi SILC client's
3718 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3720 * Added `task_max' field to the SilcClientParams to indicate
3721 the maximum tasks the scheduler can handle. If set to zero,
3722 default values are used. Affected file lib/silcclient/silcapi.h.
3724 * Fixed memory leaks in silc_client_close_connection. Affected
3725 file lib/silcclient/client.c.
3727 * Added silc_client_del_client_entry to client library to free
3728 all memory of given client entry. Affected file is
3729 lib/silcclient/idlist.[ch].
3731 * Added new functions silc_client_del_channel and
3732 silc_client_del_server to delete channel and server entries.
3733 Affected file lib/silcclient/[silcapi.h/idlist.c].
3735 * Removed silc_client_del_client_by_id from silcapi.h.
3737 * Fixed the INFO command to return the server's own info
3738 correctly when querying by Server ID. Affected file is
3741 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3743 * Removed the non-blocking settings in WIN32 code in the
3744 silc_sock_[read/write] and added SleepEx instead. Affected
3745 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3746 of input data is now checked with FIONREAD and ioctlsocket.
3748 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3750 * Call silc_schedule_task_del_by_context in the
3751 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3752 Affected file lib/silccore/silcprotocol.c.
3754 * Call silc_protocol_cancel for active protocols in the
3755 silc_server_close_connection if the funtion
3756 silc_server_free_sock_user_data has not been called.
3757 Affected file silcd/server.c.
3759 * Generic tasks cannot be deleted using the del_by_fd
3760 task deleting function since generic tasks does not match
3761 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3763 * Added a notion to SILCOPER help file that the SILCOPER works
3764 only on router server, not on normal server.
3766 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3768 * Added for WIN32 support for the new scheduler as well.
3769 Affected file lib/silcutil/win32/silcwin32schedule.c.
3771 * Fixed the SHA1 implementation to work on various platforms.
3773 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3775 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3776 API. It is part of the scheduler now. Everything else is
3777 as previously but some functions has changed their names.
3778 Checkout the lib/silcutil/silcschedule.h for the interface.
3779 Updated all applications to use the new interface. Affected
3780 files are lib/silcutil/silcschedule.[ch].
3782 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3784 * Found a bug in the SKE implementation. The HASH value,
3785 specified by the protocol, was not computed correctly. The
3786 public key of the responder was not added to the computation
3787 even though it is mandatory. Affected file lib/silcske/silcske.c.
3788 This unfortunately causes incompatibilities with older
3789 clients and servers.
3791 * Added WIN32 specific network init and uninit functions:
3792 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3793 the Winsock2. Affected file lib/silcutil/silcnet.h and
3794 lib/silcutil/win32/silcwin32net.c.
3796 * Set the socket always to nonblocking mode on WIN32 after
3797 reading data or writing data. Affected file is
3798 lib/silcutil/win32/silcwin32sockconn.c.
3800 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3802 * Fixed various compilation problems under WIN32. Affected
3803 files lib/silcutil/win32/silcwin32thread.c and
3804 lib/silcutil/win32/silcwin32schedule.c.
3806 * Removed all _internal.h #includes from public header
3807 files. Internal headers must never be included from
3810 Removed also the lib/silcske/payload_internal.h file.
3812 * All include files that may be needed (public and some others
3813 included by the public headers) by application developers are
3814 now copied to the ./includes directory. It does not copy any
3815 internal headers. Affected file Makefile.defines.pre and all
3816 Makefile.am's under lib/ and subdirs.
3818 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3820 * Do not change the ~/.silc directory's permissions automatically.
3821 Affected file irssi/src/silc/core/clientutil.c.
3823 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3825 * Do not cancel the protocol in silc_server_close_connection
3826 it might cause recursion. Now cancelled in the function
3827 silc_server_free_sock_user_data. Affected file silcd/server.c.
3829 * Fixed the silc_server_remove_clients_by_server to regenerate
3830 the channel keys correctly finally. Added also new function
3831 silc_server_remove_clients_channels to actually do it.
3832 Affected file silcd/server.c.
3834 * Fixed the silc_server_new_channel to not crash by giving
3835 wrong router to the new channel. Affected file is
3836 silcd/packet_receive.c.
3838 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3840 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3841 which is given as argument to the silc_client_alloc now.
3842 It can be used to configure the client and set various parameters
3843 that affect the function of the client.
3845 * The USERS command in server did not check whether the channel
3846 is private or secret. Affected file silcd/command.c.
3848 * Added new argument to the USERS command in protocol specification.
3849 The USERS command now can take the channel name as argument
3850 as well. Added support for this in client and server and
3851 updated the protocol specs.
3853 * Completed the GETKEY command in client. It can be now used
3854 to fetch also servers public key not only some clients.
3855 Affected files lib/silcclient/command[_reply].c.
3857 * Added silc_client_get_server to return server entry by the
3858 server name. Affected files lib/silcclient/silcapi.h and
3861 * Redefined the IDENTIFY command in protocol specification to be
3862 more generic. It now can be used to query information about
3863 any entity in the SILC Network, including clients, servers and
3864 channels. The query may be based either the entity's name
3865 or the ID. Added support for this in both client and server.
3867 Affected files silcd/command.c and lib/silcclient/command.c
3868 and command_reply.c.
3870 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3871 the _from_client and _from_server functions. Affected file
3874 * Added silc_client_get_channel_by_id_resolve to the file
3875 lib/silcclient/silcapi.h to resolve channel information by
3876 its ID. Added also silc_client_get_channel_by_id that
3877 does not resolve it from the server.
3879 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3881 * Added SilcServerEntry context into the client library
3882 to represent one server. The INFO command now allocates
3883 these to save the resolved server info. For now on the
3884 client library will also keep information about servers,
3885 connected and resolved with INFO.
3887 The INFO command now allocates the SilcServerEntry context
3888 and saves the server info there. The COMMAND_REPLY in
3889 the INFO now returns the parameters to application in
3890 same order as defined in the protocol specification.
3892 The entries are cached in the client->server_cache.
3894 * The INFO command is now issued after received the Client ID
3895 from the server. Affected file lib/silcclient/client.c.
3897 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3898 to the application as the mode changer might be server.
3899 It is guaranteed that NULL is not returned anymore to the
3900 application. Affected file lib/silcclient/client_notify.c.
3902 The ID Type is now also passed to the application so that
3903 it can check whether the returned entry is SilcClientEntry
3906 Added new function silc_client_get_server_by_id to return
3907 the server entry by ID. Affected files are the
3908 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3910 * Do not create the channel in the Irssi SILC Client when issuing
3911 the JOIN command but when received the sucessful JOIN command
3912 reply. Otherwise the channel might get created even though we
3913 could not join it. The Affected file is
3914 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3916 * Fixed a channel joining bug in router. The router must also
3917 check the channel modes, invite and ban lists etc. when serving
3918 the JOIN command sent by normal server. Affected file is
3919 silcd/command.c. The router now resolves the client's
3920 information from the server who sent the JOIN command if it
3921 does not know it, and processes the JOIN command only after
3924 * Changed the SilcCommandCb to take new argument; void *context2.
3925 Affected file lib/silccore/silccommand.h
3927 The second argument in the command callbacks in the server now
3928 includes the SilcServerCommandReplyContext if the command was
3929 called as pending command callback from the command reply.
3930 Otherwise it is NULL. When called as pending the status of the
3931 command reply will be checked and if it was erronous the
3932 error will be sent to the original sender of the command.
3933 This way the client always receives the error messages even
3934 though the server was actually the one who received the error
3935 when it resent the command to router, for example. Affected
3936 files silcd/command[_reply].[ch].
3938 * Fixed sending WHOWAS command's error message to client if
3939 the requested client could not be found. It was missing.
3942 * Changed the CMODE and CUMODE commands reply arguments in the
3943 protocol specification. The Channel ID is now sent in both
3944 of the commands to identify the channel. Implemented this
3945 new feature to the client and server. Affected files
3946 lib/silcclient/command_reply.c and silcd/command.c.
3948 * Made better checks for invite and ban lists in the JOIN
3949 command in server. Affected file silcd/command.c.
3951 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3953 * The server now performs the incoming host IP/DNS lookup
3954 using the silc_socket_host_lookup and thus does not block
3955 the server anymore. Affected file silcd/server.c.
3957 * Completed the multi-thread support for SILC Scheduler in
3958 the lib/silcutil/silcschedule.c.
3960 * Fixed the configure.in.pre to detect the pthread correctly
3963 * Fixed a deadlock in silc_task_queue_wakeup in the file
3964 lib/silcutil/silctask.c.
3966 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3968 * Added new function silc_schedule_wakeup that is used in
3969 multi-threaded environment to wakeup the main thread's
3970 schduler. It needs to be used when a thread adds a new task
3971 or removes a task from task queues. After waking up, the
3972 scheduler will detect the task queue changes. If threads
3973 support is not compiled in this function has no effect.
3974 Implemented the wakeup mechanism to both Unix and WIN32
3975 systems. Affected files are lib/silcutil/silcschedule.[ch],
3976 lib/silcutil/unix/silcunixschedule.c and the
3977 lib/silcutil/win32/silcwin32schedule.c.
3979 * Added new function silc_task_queue_wakeup to wakeup the
3980 scheduler by the specified task queue. Affected file
3981 lib/silcutil/silctask.[ch].
3983 * The silc_socket_host_lookup_start now wakes up the scheduler
3984 after adding the timeout task. Affected file is
3985 lib/silcutil/silcsockconn.c.
3987 * The silc_socket_host_lookup is synchronous now if the threads
3988 support is not compiled in. However, the callback is still
3989 called asyncronously through the scheduler, anyway. Affected
3990 file lib/silcutil/silcsockconn.c.
3992 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3994 * Added new function silc_socket_host_lookup to perform
3995 asynchronous IP and FQDN lookups for the socket connection.
3996 Affected files lib/silcutil/silcsockconn.[ch].
3998 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4000 * Added SILC_MUTEX_DEFINE to define the mutex on environments
4001 that may or may not compile the mutex support in.
4003 Changed the silc_mutex_alloc interface. It allocates the
4004 mutex now to the sent pointer and returns TRUE or FALSE.
4006 Affected file lib/silcutil/silcmutex.h.
4008 * Wrote the SILC Task Queue interface to support multi-threads.
4009 Affected file lib/silcutil/silctask.[ch].
4011 * Wrote the SILC Scheduler to support multi-threads. Affected
4012 file lib/silcutil/silcschedule.c.
4014 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4016 * Implemented the SILC Mutex API and SILC Thread API for WIN32
4017 in lib/silcutil/win32/.
4019 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4021 * Defined SILC Mutex API and SILC Thread API and implemented
4022 them for Unix. Affected files are
4023 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
4024 lib/silcutil/unix/silcunixmutex.c and
4025 lib/silcutil/unix/silcunixthread.c.
4027 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4029 * Fixed the silc_server_remove_clients_by_server's channel
4030 key re-generation. The hash table handling was incorrect
4031 and would not work with many channels. Affected file is
4034 * Fixed some memory leaks around the server code.
4036 * Rewrote the silc_server_get_users_on_channel to support IPv6
4037 based Client ID's. Affected file silcd/server.c.
4039 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
4040 specification. However, a separate document must be written
4041 to define the detailed signing procedure and the payload
4042 associated with the flag. Defined the flag to the
4043 lib/silccore/silcchannel.h as well.
4045 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4047 * Changed the dynamic tables to static size tables in the
4048 lib/silccrypt/silchmac.c.
4050 * Removed GCC dependencies from the code. A patch by cras.
4052 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4054 * Do not show the error "Error receiving packet bla bla"
4055 in server if it really was not an error (-2 means that reading
4056 is pending). Affected file silcd/server.c.
4058 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4060 * Fixed a possible crash in silc_server_remove_clients_by_server
4061 in silcd/server.c. Fixed there also some memory leaks.
4063 * Fixed the silc_idlist_replace_client_id. It could replace
4064 wrong key in the hash table. Affected file silcd/idlist.c.
4066 * Do not check whether there are global users on the channel
4067 if the channel->global_users is FALSE. Affected functions
4068 silc_server_remove_from_one_channel and
4069 silc_server_remove_from_channels in silcd/server.c. Also,
4070 do not check if the removed client is local as we can be
4071 sure that global client was not removed from the channel
4072 and checking for global users is not needed.
4074 * The silc_server_remove_clients_by_server now re-generates
4075 the channel keys correctly for those channels that had
4076 clients removed from them. Affected file silcd/server.c.
4078 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4080 * Found the reason of random crashes in the server. We weren't
4081 ignoring the SIGPIPE signal (which can be sent in write())
4082 and it crashed the server. Affected file silcd/silcd.c.
4084 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4086 * Assure that sock->user_data is not NULL in the function
4087 silc_server_packet_send in silcd/packet_send.c.
4089 * Disconnect the remote connection if it could not be added
4090 to any ID lists in the server. The affected file is
4093 * Check in silc_server_packet_send[_real/dest] that the
4094 socket is not disconnecting and ignore the data if it is.
4095 Affected file silcd/packet_send.c.
4097 * Define inline to __inline on native WIN32 compilation.
4098 Affected file includes/silcwin32.h.
4100 * Added some explicit type casts for inline code since MSVC
4101 require them. Affected files lib/silcutil/silcbuffer.h,
4102 lib/trq/silcdlist.h and lib/trq/silclist.h.
4104 * Print warning in log files from now on if the packet
4105 decryption fails. Affected file silcd/server.c.
4107 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4109 * Changed the `say' client operation's interface to accept
4110 new `type' argument to indicate the type of the message sent
4111 by the library. The application may filter the library's
4112 messages according the type. The affected file is the
4113 lib/silcclient/silcapi.h.
4115 * Added two new functions to lib/silcclient/silcapi.h:
4116 silc_client_del_client and silc_client_del_client_by_id.
4117 Affected file lib/silcclient/idlist.c.
4119 * Moved the clientincludes.h from includes/ to silc/ and
4120 serverincludes.h from includes/ to silcd/.
4122 * The modes for the CMODE and CUMODE are now passed as
4123 uint32 for application with COMMAND_REPLY. The affected
4124 file is lib/silcclient/command_reply.c.
4126 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4128 * /WHOIS without arguments shows client's own information.
4129 Affected file lib/silcclient/command.c.
4131 * Changed PING to not accept any arguments. The specs
4132 says that client can ping only the connected server so
4133 requiring an argument is not needed. Affected file is
4134 lib/silcclient/command.c.
4136 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4138 * Fixed a fatal bug in private message sending and reception
4139 encryption and decryption when using private message keys.
4140 The implementation was incorrect and did not follow the
4141 specification. It causd that some of the message were
4142 lost since it did not use the sending and receiving keys
4143 as the protocol suggests. This has been fixed and will cause
4144 incompatibilities with older clients when sending private
4145 message encrypted with private message keys. Affected files
4146 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
4147 and various other in Irssi SILC Client.
4149 Added `responder' boolean argument to the functions
4150 silc_client_add_private_message_key[_ske] to indicate when
4151 the key is added as responder or initiator of the key
4154 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4156 * Removed the silc_ske_check_version function and created
4157 a SilcSKECheckVersion callback. Added also a function
4158 silc_ske_set_callbacks that is now used to set all SKE
4159 callbacks. The callback functions are not given to
4160 the SKE functions anymore, but this function is used to
4163 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
4165 * Added `silc_version' argument to the silc_client_alloc
4166 to define the version of the application for the library.
4167 The library will use the version string to compare it
4168 against the remote host's (usually a server) version
4169 string. Affected file lib/silcclient/silcapi.h
4171 * Added the KE protocol context to Key Agreement context
4172 in client library so that we can abort the SKE if it
4173 is in process when we get timeout. Affected file is
4174 lib/silcclient/client_keyagr.c.
4176 * Do not resolve the client ID forever if it returns in the
4177 first time that such client does not exist. This was done
4178 for example with private message. Affected file is
4179 lib/silcclient/client_prvmsg.c.
4181 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4183 * Do not add regex.h for WIN32. The affected file
4184 includes/silcincludes.h.
4186 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
4187 not work yet 100%. It generates the DLL's automatically
4188 when compiling with --with-win32 under cygwin.
4190 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4192 * lib/contrib/regex.c is not compiled on WIN32.
4194 * Added silc_net_get_socket_opt function to the
4195 lib/silcutil/silcnet.h.
4197 * Added includes/silcwin32.h for WIN32 specific includes
4200 * Do not use ptime structure or any of the posix process
4201 functions on WIN32 in lib/silccrypt/silrng.c.
4203 * Added silc_gettimeofday to provide generic function
4204 for struct timeval on all platforms. Added the function
4205 to lib/silcutil/silcutil.h.
4207 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4209 * Moved the lib/silccore/silcsockconn.[ch] to the utility
4210 library as they clearly belong there. As a plus side we
4211 can make the actual socket connection routines platform
4214 Added also new generic function silc_socket_read and
4215 silc_socket_write (that used to be silc_packet_[read/write].
4216 The implementation of these are platform specific.
4218 * Added WIN32 specific routines of silc_socket_[read/write]
4219 to lib/silcutil/win32/silcwin32sockconn.c.
4221 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4223 * Added preliminary support for native WIN32 compilation under
4224 cygwin (using the -mno-cygwin option for GCC) to the
4225 ./configure.in.pre. The --with-win32 now prepares the
4226 compilation for native WIN32.
4228 * Rewrote the SILC Scheduler interface in the file
4229 lib/silcutil/silcschedule.h. The scheduler is now context
4230 based and does not have anymore any global static scheduler.
4231 Moved the Unix scheduler to the lib/silcutil/unix/ directory
4232 and created lib/silcutil/win32 directory for WIN32 based
4235 * Added Unix specific network routines to the
4236 lib/silcutil/unix/silcunixnet.c and the old
4237 lib/silcutil/silcnet.c includes now only generic routines.
4239 Added WIN32 specific network routines to the
4240 lib/silcutil/win32/silcwin32net.c.
4242 * Added Unix specific utility functions from the
4243 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
4245 * Added WIN32 SILC Scheduler to the file
4246 lib/silcutil/win32/silcwin32schedule.c. The code is of course
4249 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4251 * Do not handle JOIN notify in the server if the target client
4252 is not registered (idata->registered == FALSE). The affected
4253 file is silcd/packet_receive.c.
4255 * Update the nickrec->founder in event_cumode in the Irssi SILC
4256 client. Affected file irssi/src/silc/core/silc-channels.c.
4258 * Fixed the CUMODE_CHANGE notify handling in the server when
4259 server and router are announcing their clients on channels.
4260 Now the mode changes are saved and notified correctly. The
4261 affected file is /silcd/packet_receive.c.
4263 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
4264 They really did not replace the cache entry in the ID Cache.
4265 Now they do that. Affected file silcd/idlist.c.
4267 * Fixed the KICK notify handling in the Irssi SILC client to
4268 update the channel records so that the kicked client does not
4269 appear to be on the channel. The affected file is
4270 irssi/src/silc/core/silc-channels.c.
4272 * Always update the conn->current_channel when executing command
4273 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
4275 * Fixed the KILL notify handling in Irssi SILC client to remove
4276 the killed client on all channels.
4278 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4280 * Fixed the silc_parse_command_line to remove extra spaces
4281 from the start and end of the arguments. Affected file is
4282 lib/silcutil/silcutil.c.
4284 * Cancel and free any active protocol in the function
4285 silc_server_close_connection. Affected file silcd/server.c.
4287 * Cancel and free any active protocol in the function
4288 silc_client_close_connction. Affected file is
4289 lib/silcclient/client.c.
4291 * Do not execute the KILL command for clients that are in
4292 history (ie. they are not in the network). Affected file is
4295 * Fixed KILL notify handling, client does not crash anymore.
4296 Affected file irssi/src/silc/core/silc-channels.c.
4298 * Reduced the default packet buffer size from 2048 to 1024 in
4299 lib/silccore/silcpacket.c.
4301 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
4302 counter to the SKE context that is incresed when the SKE library
4303 performs async operation outside the library. If the outside
4304 process frees the SKE context and FREED status will be set
4305 and the library will detect after the sync operation that the
4306 libary is freed. The affected files are
4307 lib/silcske/silcske[_status].[ch].
4309 * Resolve the client entry information in the function
4310 silc_client_channel_message to assure that NULL pointer is not
4311 passed as client entry to the application. */
4313 * Fixed the task timeout calculation to assure that there is
4314 never negative timeouts. The affected file is
4315 lib/silcutil/silcschedule.c.
4317 * Fixed the channel user mode notification sending in server.
4318 It was sent point-to-point to the router (or to server by router)
4319 but it needs to be destined to a channel. The routines now
4320 supports sending the channel user mode notifys to the channels
4321 when announcing clients and channels. Affected files are
4322 silcd/server.c and silcd/packet_receive.c.
4324 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
4325 It did not actually replace the old channel entry in the cache.
4326 Affected file lib/silcclient/client_notify.c.
4328 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4330 * Fixed a possible crash in silc_packet_send_prepare. It now
4331 assures always that there is enough space in the buffer and
4332 at the tail area of the buffer (for MAC).
4334 Fixed the inbound buffer reallocation in silc_packet_read.
4335 It was old code and did not handle the reallocation correctly.
4338 The affected file is lib/silccore/silcpacket.c.
4340 * Fixed buffer overflow in silc_parse_nickname in the file
4341 lib/silcutil/silcutil.c.
4343 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4345 * make install generates new server keys only if there is not
4348 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4350 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
4351 Added check that if the NOREPLY is set then we will not send
4352 the away message. This avoids infinite loop of away messages
4353 if both clients are away. The affected file is
4354 lib/silcclient/client_prvmsg.c.
4356 * Fixed client crash if /NICK was given without arguments.
4357 Affected file lib/silcclient/command.c.
4359 * Server does not send the invite list in INVITE command back
4360 to the client if the list was not altered. Added this notion
4361 to the protocol spec as well. Affected file silcd/command.c.
4363 Fixed possible crash in INVITE command by checking the
4364 value of silc_server_get_client_route command.
4366 * Fixed the INVITE notify type handling. The arguments are now
4367 taken in correct order and client does not crash. The affected
4368 file is irssi/src/silc/core/silc-channels.c.
4370 Removed the "Inviting xxx to channel" message from the
4371 client library away and let the application handle it.
4372 Affected file lib/silcclient/command.c. Added that message
4373 to Irssi SILC client's message formats.
4375 * Fixed CMODE command crash in client. It now checks the
4376 amount of arguments correctly and does not crash. The affected
4377 file is lib/silcclient/command.c.
4379 * Do not create new channel automatically in silc_channels_join
4380 but check whether the channel by that name already exists.
4381 Affected file irssi/silc/core/silc-channels.c.
4383 * Do not send the SERVER_SIGNOFF to router if the disconnected
4384 entity was the router. Affected file silcd/server.c.
4386 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
4387 SILC client as it was missing from there.
4389 Added the handling of the KICK notify to the Irssi SILC client
4390 as it was missing. Added "you have been kicked" message to
4391 Irssi SILC client's message modules formats.
4393 Added the handing of the KILL notify to the Irssi SILC client
4394 as it was missing. Added the kill message module formats
4397 The affected file is irssi/src/silc/core/silc-channels.c.
4399 * The router did not save the channel mode the server announced.
4400 Affected file silcd/packet_receive.c.
4402 * Fixed a possible crash in INFO command in server. If the
4403 server did not provide the server info it crashed. Affected
4404 file silcd/command.c.
4406 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4408 * Fixed the GETKEY command in the server to check also the
4409 global list. Otherwise the GETKEY would not work correctly
4410 in normal SILC server. Affected file silcd/command.c.
4412 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4414 * Fixed GETKEY crash, it crashed if the command did not succseed.
4416 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4418 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
4419 is now real and not just an macro interface to GMP.
4421 Removed the entire GMP from the source tree and imported new
4422 NSS MPI library instead. Reason for removing GMP is that it is
4423 extremely large and compiles extremely slow. The NSS MPI
4424 is only a few files and compiles in less than 10 seconds.
4425 The speed is also about the same as GMP. The MPI is imported
4426 to lib/silcmath/mpi.
4428 If the system has GMP installed we will still use the GMP.
4429 If it is not then the NSS MPI will be compiled.
4431 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4433 * Merged a long nickname (127 characters long) crash bugfix from
4434 Irssi CVS tree. Affected file irssi/src/core/misc.c.
4436 * Merged a freed memory reference bugfix from Irssi CVS tree.
4437 Affected file irssi/src/core/commands.c.
4439 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4441 * Added the server's public key sving and verification to the
4442 server when performing the SKE. This was missing and the
4443 remote server's (or router's) public key was accepted without
4444 checking whether we have it previously or trust it at all.
4445 Affected file silcd/protocol.c.
4447 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4449 * Check in the silc_server_timeout_remote if protocol is active
4450 and make sure that the protocol's final callback is called so
4451 that all memory if freed. Affected file silcd/server.c.
4453 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4455 * silc_server_whois_send_reply crashed the server if the nickname
4456 was 127 characters long. Affected file silcd/command.c.
4458 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4460 * Added sanity check to the silc_server_new_client. If the hostname
4461 is provided inside username then check that the provided hostname
4462 really is the same as the resolved one. If the hostname was not
4463 resolved then check it from the public key. Affected file is
4464 silcd/packet_receive.c.
4466 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
4467 if the server disconnected us and the connection is not valid
4468 anymore. Affected file irssi/src/silc/core/silc-channels.c.
4470 * Moved the silc_client_[chmode|chumode|chumode_char] away from
4471 the library to the lib/silcutil/silcutil.[ch].
4473 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4475 * Close log file after open. Affected file
4476 lib/silcutil/silclog.c.
4478 * Check whether sock == NULL in silc_client_send_packet and return
4479 if it is. Affected file lib/silcclient/silcclient.c.
4481 * Check rec->entry == NULL in the Irssi SILC Client before
4482 sending the channel message. Affecte file is
4483 irssi/src/silc/core/silc-servers.c.
4485 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4487 * Merged a splitted window bugfix from Irssi CVS tree. The
4488 affected file is irssi/src/fe-text/textbuffer-view.c.
4490 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
4491 It did not print nickname.
4493 * Improved the distributions system a bit.
4495 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4497 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
4498 irssi/src/fe-text/gui-window.c.
4500 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
4501 to in-active server. The affected file is
4502 irssi/src/silc/core/client_ops.c.
4504 * Resolve the client in USERS command reply if the entry does
4505 not have username resolved. The affected file is
4506 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
4507 command to WHOIS command to really resolve stuff. The USERS
4508 is not used any more in any critical section so WHOIS can
4509 be used even though it might be slower than IDENTIFY.
4511 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
4514 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4516 * Changed the protocol API a bit more consistent in the
4517 lib/silccore/silcprotocol.[ch].
4519 * Changed the following headers to ROBODoc format:
4521 lib/silccore/silcpayload.h
4522 lib/silccore/silcprotocol.h
4523 lib/silccore/silcsockconn.h
4525 All core library headers are now formatted.
4527 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4529 * Fixed a bug in Irssi SILC client; do not show that you are
4530 server/router operator if you really are not. Affected file is
4531 irssi/src/silc/core/client_ops.c.
4533 * Renamed silc_command_free_payload to silc_command_payload_free.
4534 Affected file lib/silccore/silccommand.h
4536 * Added silcmath.h to include the prototoypes of various routines
4537 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
4540 * Changed the following headers to ROBODoc format:
4542 lib/silccore/silcchannel.h
4543 lib/silccore/silccommand.h
4544 lib/silccore/silcid.h
4545 lib/silccore/silcidcache.h
4546 lib/silccore/silcmode.h
4547 lib/silccore/silcnotify.h
4548 lib/silccore/silcpacket.h
4549 lib/silcmath/silcmath.h
4551 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4553 * Added checking to the server code not to start the server if
4554 ciphers and stuff are not configured properly. Affected files
4555 silcd/serverconfig.[h] and silcd/server.c.
4557 * Changed the layout of the header files of the public interfaces
4558 in the SILC libraries. The new layout supports ROBODoc
4559 documentation tool (and some others) so that it is easy to create
4560 a library reference manual. All the other headers and source
4561 code must still follow the CodingStyle document. Also source
4562 code must not include these ROBODoc stuffs, only the headers.
4563 Furthermore, all public interface headers must now be named
4564 by using `silc' prefix, example: silcapi.h, silccipher.h.
4565 Some files were renamed due to this. All the other headers
4566 must not be used as public interfaces. I will update the
4567 CodingStyle document later. Changed following headers, so far:
4569 lib/silcclient/silcapi.h
4570 lib/silccore/silcauth.h
4571 lib/silccore/silcprivate.h
4572 lib/silccrypt/silcdh.h
4574 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4578 * Removed silc_client_packet_send_flush from the client library
4579 as it is not needed. Affected file lib/silcclient/client.[ch].
4581 * Added printing of message of unresolved authentication method
4582 to the Irssi SILC client. Added it to the module formats.
4583 Removed the same message from the client library.
4585 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4587 * Added new distribution feature, DISTLABEL. Every distribution
4588 can define own preprocessor label that can be used in the
4589 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
4590 file distributions, acconfig.h.pre and prepare.
4592 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4594 * Added Makefile.defines_int to include the actual definitions
4595 for Makefile.defines.in. Tested the new distribution system,
4596 created distributions and tested installation.
4598 * Added AWAY message printing to the Irssi SILC client. Added
4599 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
4601 * Added SCONNECT command to call the SILC's CONNECT command.
4602 Cannot use CONNECT directly since Irssi uses that internally.
4603 Affected file irssi/src/silc/core/silc-servers.c.
4605 Added ACTION local command. It is same as ME command but takes
4606 the channel as mandatory argument.
4608 Rewrote some of the Irssi's help files to suite for SILC
4611 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4613 * Added Makefile.defines[.in] that should for now on be included
4614 in all Makefile.am file in the source tree. That file includes
4615 all common compilation definitions for SILC source tree.
4617 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4619 * Minor changes to the ./prepare script to change the package
4620 name according the distribution name to the configure.in.
4622 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4624 * Created new distribution system. Added file `distributions'
4625 that defines all the distributions that can be created out of
4626 the SILC source tree. The ./prepare script now reads that
4627 file to determine how to prepare the distributions. The
4628 first argument to the ./prepare is the name of the distribution
4629 and second is the version of the distribution. If given
4630 without arguments it creates the default (toolkit) distribution
4631 with the default version (defined in ./prepare).
4633 All Makefile.am files that are subject to the distributions
4634 are now named as Makefile.am.pre. These are ./Makefile.am
4635 and lib/Makefile.am. Others may be changed later.
4637 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4639 * Added invite list, ban list, some key management and connection
4640 error message printing to module formats in the Irssi SILC client.
4642 * Added new silc_client_set_away_message to set the away message
4643 that is back to the person who sent private message. The
4644 affected file lib/silcclient/silcapi.h and the
4645 lib/silcclient/client_prvmsg.c.
4647 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4649 * Fixed the private message sending in the Irssi SILC client,
4650 added local command KEY to the Irssi SILC client.
4652 Added key management and key agreement message formats to the
4653 irssi/src/fe-common/silc/module-formats.[ch].
4655 Added USERS (alias WHO) printing, server/router operator
4656 indication and LIST command printing to the module formats.
4658 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4660 * Fixed channel joining notify handling, cumode notify handling
4661 from Irssi SILC client.
4663 * Added SILC specific module-formats to the Irssi SILC client so
4664 that SILC specific message hilighting, colors etc is possible.
4665 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4667 Added channel mode, channel user mode, actions, notices,
4668 whois and whowas printing to the the module-formats.c.
4670 * Fixed a bug in channel deletion in the server. The channel
4671 is not left to the cache even if the channel founder auth mode
4672 is set when there are no users anymore on the channel. Affected
4673 file silcd/server.c.
4675 * The silc_net_localhost now resolves the entire hostname including
4676 the domain name. Affected file lib/silcutil/silcnet.c.
4678 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4680 * Changed the ask_passphrase client operation to be ascynchronous.
4681 It has now a completion callback and a context that the
4682 application must call after it has got the passphrase from
4683 the user. Affected files lib/silcclient/silcapi.h,
4684 lib/silcclient/protocol.c, lib/silcclient/command.c and
4687 Added SilcAskPassphrase callback that the application calls
4688 to deliver the passphrase to the library.
4690 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4691 The public key verification and especially a certificate
4692 verification is asynchronous procedure.
4694 Added new SILC_SKE_STATUS_PENDING status to indicate the
4695 request is pending and a callback will be called to finalize
4698 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4699 indicate that remote end did not send its public key (or
4700 certificate), even though we require it. Added check for this
4701 condition in the SKE. This was a security bug, now fixed.
4703 Defined new SilcSKEVerifyCbCompletion callback that is called
4704 when the verification process is completed.
4706 The affected files lib/silcske/silcske_status.h and
4707 lib/silcske/silcske.[ch].
4709 * Changed the verify_public_key client operation to be async
4710 as well. Defined SilcVerifyPublicKey callback that is used to
4711 indicate the success of the public key verification process.
4713 Changed the server and client to use the new async client
4716 * Changed the Irssi SILC client's internal scheduler to be called
4717 twice as many times as it used to be. As a result the client
4718 should be a bit faster now. Affected file is
4719 irssi/src/silc/core/silc-core.c.
4721 * Added support to Irssi SILC client of asynchronous public key
4722 verification and passphrase inquiry. Affected file is
4723 irssi/src/silc/core/silc-core.c.
4725 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4727 * Do not say "You have left channel %s" in client library.
4728 Moved it to the application. Affected files are
4729 lib/silcclient/command.c and silc/client_ops.c.
4731 * Fixed silc_client_get_clients. Command context was not
4732 duplicated and was freed memory in the callback. Affected
4733 file lib/silcclient/idlist.c.
4735 * Do not say "you are now talking..." on JOIN command in the
4736 client library. The appliation must handle it.
4738 * Do not say ".. changed topic to" in command reply in the
4739 client libary. The application must handle it.
4741 * Fixed TOPIC command sending in the client library.
4743 * Fixed a memory leak in silc_client_command_free in the file
4744 lib/silcclient/command.c.
4746 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4748 * Imported a modified version of Irssi client to the source tree.
4749 The Irssi will be used to create a new client called
4750 Irssi SILC. Imported to irssi/.
4752 Added silc_core_init_finish function to the Irssi. Affected
4753 file irssi/configure.in.
4755 A lot changes in the Makefile.ams around the irssi tree.
4757 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4759 * Do not rehash if the new size is same as the old size of the
4760 hash table, in the silc_hash_table_rehash*. The affected file
4761 lib/silcutil/silchashtable.c.
4763 * Replaced hash_table_del_by_context calls from the server
4764 (when channel->user_list and client->channels) to the
4765 hash_table_del as it is sufficient and faster.
4767 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4769 * Added silc_hash_table_list, silc_hash_table_get and the
4770 SilcHashTableList structure to provide an alternative way to
4771 traverse the hash table. The affected files are
4772 lib/silcutil/silchashtable.[ch].
4774 * Changed the server's idlist routines to use the hash table
4775 routines to optimize the code.
4777 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4779 * Replaced the client entry's `channel' list and channel entry's
4780 `user_list' list to hash tables for optimized lookup. Changed
4781 the code to use the hash table interface around the code.
4782 Affected file lib/silcd/idlist.[ch].
4784 * Added `auto_rehash' boolean argument to the function
4785 silc_hash_table_alloc to indicate whether the hash table should
4786 auto-rehash when it thinks is appropriate time. It will
4787 increase the hash table size if the there is twice as much
4788 entries in the table than the size of the table, and will
4789 decrease the size if there are twice as less entries than
4790 the size of the table.
4792 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4794 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4796 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4798 * silc_idcache_purge_by_context deletes the entry now by context
4799 as it is supposed to do. Affected file lib/silccore/idcache.c.
4801 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4802 client is not anymore valid (WHOWAS givens the info) and not
4803 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4805 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4807 * Removed the `data' and `data_len' arguments from the ID Cache
4808 interfaces and added `name' argument. ID Cache does not handle
4809 anymore the binary data only a names associated with given ID.
4811 * When hashing a Client ID with silc_hash_id the entire ID is
4812 not hashed anymore, instead only the hash of the Client ID is
4813 hashed. This way we can access the Client ID from the cache
4814 with Client ID but with the hash of the ID (which is a hash of
4815 the nickname) as well without any difference in performance.
4817 Added also silc_idcache_find_by_id_one_ext to do one on one
4818 searching when we have the actual ID. Added also function
4819 silc_hash_client_id_compare. The affected files are
4820 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4822 * When hashing the name associated with a ID it is always done
4823 in lowercase. This way we can access the cache without worrying
4824 about case-sensitivity, even though, for example nicknames are
4827 * Fixed a bug in server with channel message sending. It put
4828 wrong ID type as destination ID. The affected file
4829 silcd/packet_send.c.
4831 * silc_idcache_del_by_context now deletes from all hash tables
4832 by context. Affected file lib/silccore/idcache.c.
4834 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4836 * Changed the client library to use the new ID Cache interface.
4837 Changes around the source tree.
4839 * Added silc_hash_table_rehash_ext to rehash with specific
4840 hash function. Affected file lib/silcutil/silchashtable.[ch].
4842 * Added silc_hash_string_compare to compare two strings in the
4843 hash table. Affected file lib/silcutil/silcutil.[ch].
4845 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4847 * Added new function silc_idcache_del_by_context into the
4848 lib/silccore/idcache.[ch].
4850 * Changed the server's ID list routines to use the new ID Cache
4851 interface. Changes around the source tree.
4853 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4855 * Added silc_hash_table_del[_by_context]_ext functions in to the
4856 lib/silcutil/silchashtable.[ch].
4858 Removed silc_hash_table_find_all* routines and added new
4859 silc_hash_table_find_foreach to replace them.
4861 Added silc_hash_table_replace_ext function as extended
4862 replacing function. Separated the simple hash table interface
4863 from the extended hash table interface in the file
4864 lib/silcutil/silchashtable.h.
4866 * Fixed minor bugs and changed it to use some of the new
4867 hash table functions in lib/silccore/idcache.c
4869 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4871 * Added new function silc_hash_table_find_all to return all keys
4872 in the hash table by the specified key. As the hash table is
4873 collision resistant it also makes it possible to have several
4874 duplicate keys in the hash table. This function may be used to
4875 find all of the keys from the hash.
4877 Added user_context arguments to the SilcHashFunction,
4878 SilcHashCompare and SilcHashDestructor to deliver user specified
4881 Added new fuctions silc_hash_table_find[_all]_ext to do
4882 extended lookup with specified hash and compare functions and
4883 specified user contexts.
4885 Added new function silc_hash_table_add_ext to add the key
4886 with specified hash function and user context.
4888 Added new function silc_hash_table_foreach to traverse all
4889 entrys in the hash table. Added SilcHashForeach callback
4892 Added new function silc_hash_table_del_by_context to delete
4893 the entry only if the context associated with the key matches.
4895 Affected files are lib/silcutil/silchashtable.[ch].
4897 * Removed silc_hash_[server/client/channel]_id and added just
4898 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4899 silc_hash_id_compare to compare two ID's using as the hash table
4900 comparison function. Added also silc_hash_data to hash
4901 binary data and silc_hash_data_compare to compare it.
4903 * Removed silc_idlist_find_client_by_hash as it is not needed
4904 anymore. Affected file silcd/idlist.[ch].
4906 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4907 to use internally the SilcHashTable. The new ID Cache is a lot
4908 faster than the old one. Some of the ID Cache interface was also
4909 rewritten and obsolete and stupid functions were removed.
4911 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4913 * Added entry_count field to the SilcHashTable to keep the number
4914 of the entries in the table. Implemented the function
4915 silc_hash_table_rehash. Added new function
4916 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4918 Fixed a minor bug in silc_hash_table_free.
4920 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4921 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4922 into the lib/silcutil/silcutil.[ch].
4924 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4926 * Implemented a collision resistant hash table into the
4927 lib/silcutil/silchashtable[ch]. See the header and the source
4928 for the SilcHashTable API.
4930 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4932 * Merged dotconf version 1.0.2 into lib/dotconf.
4934 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4936 * Do not compile anything in lib/silcsim/* if the SIM support
4937 is not enabled. The tree should now compile without problems
4940 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4942 * Compiled the SILC under cygwin. Compiled and tested briefly
4943 without problems. More tests needed. The SIMs didn't compile
4946 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4948 * Fixed possible crash in silc_get_username in the
4949 lib/silcutil/silcutil.c.
4951 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4953 * Fixed a va_arg in silc/client_ops.c.
4955 * Oops, RC5 routines were named AES and caused some problems
4956 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4958 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4960 * Added new SilcIDIP structure into the lib/silccore/id.h and
4961 replaced the old `ip' fields from all SILC ID's to that type.
4962 This is a step towards IPv6 support.
4964 The silc_id_get_len takes now the ID as an extra argument.
4965 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4966 both IPv4 and IPv6 based ID's.
4968 The affected files are lib/silccore/id.[ch] and other files
4969 around the tree using these routines.
4971 * Removed the ID length arguments in server from various
4972 silc_server_send_notify_* routines -> they are not needed
4975 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4977 * Fixed memory leak in silc_encode_pem_file in the file
4978 lib/silcutil/silcutil.c.
4980 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4982 * Check minor version as well in the SKE. Affected files are
4983 silcd/protocol.c and lib/silcclient/protocol.c.
4985 * Added --identifier option to the server so that an identifier
4986 can be when creating the public key for the server. Affected
4987 file is silcd/silcd.c.
4989 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4990 lib/silccrypt/silcpkcs.c.
4992 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4994 * Register default ciphers and stuff when using -C option with
4995 the server. Affected file sildc/silcd.c.
4997 * Put back the servers public key filename format, it is better
4998 than the new one. For now, the client keys are saved with the
4999 new filename format. The affected file silc/client_ops.c.
5001 * Implemented the Cipher API for the rest of the ciphers that
5002 did not implement it or implemented it the wrong way.
5004 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5006 * Register default ciphers and stuff when using the -S option
5007 in the client. Affected file silc/silc.c. Same also when
5008 creating new key pair with -C option.
5010 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5012 * Fixed the silc_verify_public_key client operation function to
5013 save the public keys differently. The fingerprint is now
5014 used as filename and not the hostname. This way also the
5015 client keys are saved uniquely and not with hostnames. The
5016 affected file is silc/client_ops.c.
5018 * Trimmed the silc_hash_fingerprint function to remove extra
5019 whitespaces from the end of the fingerprint. The affected
5020 file is lib/silccrypt/silchash.c.
5024 * Added silc_cipher_register_default function to register all
5025 default ciphers. It can be used when configuration files
5026 does not exist and the application does not want any specific
5027 ciphers in any specific order.
5029 The SilcDList is now used as silc_cipher_list dynamically
5030 allocated cipher list. Removed the static list all together
5031 and now all ciphers must be allocated to the dynamic list.
5032 The silc_cipher_alloc routine was changed to check only the
5035 All silc_cipher_* routines that used to return int returns
5038 The affected files lib/silccrypt/silccrypt.[ch].
5040 * The same thing was done to silc_hash_* as for silc_cipher_*
5041 routines. Affected files lib/silccrypt/silchash.[ch].
5043 * The same thing was done to silc_pkcs_* as for silc_cipher_*
5044 routines. Affected files lib/silccrypt/silcpkcs.[ch].
5045 Added also silc_pkcs_[un]register[_default] functions.
5046 Removed the data_context from the PKCS API.
5048 * Added silc_hmac_register_default function to register default
5049 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
5050 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
5051 to unregister all hmacs at once.
5053 * Register the default ciphers, hash functions, PKCSs and HMACs
5054 if client's configuration file does not exist. The affected
5057 * The client did not load the hash functions from the SIM
5058 modules at all. Added support for this. Affected file is
5059 silc/clientconfig.c.
5061 * When decoding public key with silc_pkcs_public_key_decode, check
5062 the supported algorithm only if PKCS are registered. Affected
5063 file lib/silccrypt/silcpkcs.c. The same was done with the
5064 silc_pkcs_private_key_decode.
5066 * Fixed the SILC List routines to keep the list always in order.
5067 It used to change the list's order when traversing the list but
5068 not it preserves the order. Affected file lib/trq/silclist.h.
5070 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5072 * Added the client library to use the SilcSocketConnection's
5073 reference counter (by silc_socket_dup) to prevent the bug that
5074 the socket object may be freed underneath async operation.
5076 * The name resolv library checking fixes in the configure.in.pre.
5079 * Created new version of the protocol drafts for future
5080 development. The -03 drafts are the ones that will be changed
5081 in the trunk now and the -02 will remain as they are.
5083 * Send list of CUMODE notifys to the router when announcing
5084 the channel users to the router. Affected file silcd/server.c.
5085 If the router receiving channel founder CUMODE for a channel
5086 that already has channel founder it will send CUMODE notify
5087 to the sender to remove the channel founder rights from the
5088 announced client. Affected file silcd/packet_receive.c.
5090 * The CUMODE notify may now use Server ID as well as the entity
5091 who changes the mode. Updated protocool specs.
5093 * Updated INSTALL and README files.
5095 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5097 * New web pages in the http://silc.pspt.fi. The pages was
5102 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5104 * Implemented the [DenyConnectin] config section in the server.
5105 Added silc_server_config_denied_conn to check whether incoming
5106 connection is denied. Affected file silcd/serverconfig.[ch].
5108 * Do not check the ports when checking the incoming configuration
5109 data if the port is 0, meaning any. Affected file is
5110 silcd/serverconfig.c.
5112 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5114 * Fixed buffer overflow in silc_string_compare in the file
5115 lib/silcutil/silcutil.c.
5117 * Fixed double free in silc_server_command_leave in the file
5120 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5122 * Fixed the version checking in the server. Affected file is
5125 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5127 * Fixed the configuration data fetching when accepting new
5128 connections in the server. Affected file silcd/server.c.
5130 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5132 * Added `sender_entry' argument to the function
5133 silc_server_packet_relay_to_channel so that we can check
5134 whether some destination actually belongs to the same route
5135 the sender belongs (ie, we must not resend the packet to the
5136 sender). Affected file silcd/packet_send.[ch].
5138 * Added `servername' field to the SilcClientEntry in the server
5139 to hold the name of the server where client is from. Affected
5140 file is silcd/idlist.h.
5142 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5144 * Moved the channel message encrypting in the router betwen
5145 router connections from silc_server_channel_message to the
5146 silc_server_packet_relay_to_channel since we want to check
5147 whether we have anybody channel before encrypting anything.
5148 Affected files silcd/packet_[receive/send].c.
5150 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5152 * Fixed the [AdminConnection] server config section to support
5153 multiple entries. Affected file silcd/serverconfig.c.
5155 * Added support into the server to check the validity of the
5156 incoming connection before executing any KE or authentication
5159 * The connection configuration is now saved to the KE and
5160 connection auth protocol contexts and not fetched anymore in
5161 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
5163 * The local hosts listenning address and port is also resolved
5164 now when starting the server. We want to have the socket object
5165 to include the real address and port for the listener. Added
5166 new function silc_net_check_local_by_sock into the files
5167 lib/silcutil/silcnet.[ch].
5169 * Fixed a broadcast bug in server -> do not broadcast if we
5172 * Fixed a routing bug. Do not route broadcast packets ever.
5173 Broadcast packets must be processed always and not routed since
5174 they may be destined to some other host than yourself and thus
5175 would get routed without no good reason. Affected file is
5178 * Added function silc_server_config_is_primary_route to check
5179 whether primary router connection has been configured (a router
5180 configuration that we are initiating). If there is not, we
5181 will assume that there is only two routers in the SILC network
5182 and we will use the incoming router connection as our primary
5183 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
5185 * Changed the order of the broadcasting. Broadcast _after_ the
5186 packet has been processed not before. Affected file is
5189 * Fixed a [ClientConnection] parsing bug. The port was never
5190 parsed correctly thus resulting to port 0. Affected file
5191 silcd/serverconfig.c.
5193 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
5194 argument and did not set the broadcast packet flag. Affected
5195 file silcd/packet_send.c. Fixed same bug in the function
5196 silc_server_send_notify as well.
5198 * If we receive NEW_ID packet for our own ID in the server, ignore
5201 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5205 * Removed the nickname from the Private Message Payload.
5206 Updated the code and the protocol specs.
5208 * Updated protocol specs for submitting to the IETF.
5210 * Tweaked the Random Number Generator a bit. Affected file
5211 lib/silccrypt/silcrng.c. Exported a new function
5212 silc_rng_[global]_add_noise which can be used to add more
5215 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5217 * Do not parse packets with different timeout when protocol
5218 is active -> may cause problem with rekey. Affected file
5221 * When server receives signoff notify it must not create
5222 new channel key if the client is on any channels since the
5223 sender of the signoff notify will create it.
5225 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5227 * Added printing of error messages during SKE protocol from the
5228 failure packet sent by server during SKE. Affected file
5231 * Removed the client's failure_callback handling with timeout
5232 and handle it immediately when received.
5234 * The SKE library returned wrong type in SUCCESS and FAILURE
5235 packets. They must be 32 bit MSB not 16 bit MSB.
5237 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5239 * Ok, rewrote the logic of the re-key and now it seems to work.
5240 I tested it on high traffic with frequent re-keys without
5241 problems. Added hmac_receive (and renamed hmac to hmac_send)
5242 in SilcClientConnection in lib/silcclient/client.h and
5243 in SilcIDListData in silcd/idlist.h. Also, removed the
5244 SilcPacketParserContext's cipher and hmac fields as they are
5245 not needed anymore and actually caused some problems when
5246 the ciphers and hmac's changed underneath the packet parser.
5248 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5250 * If re-key protocol is active then process the incoming packets
5251 synchronously since we must assure that icoming packets encrypted
5252 with the old key is processed before the new keys is set to
5253 use. This is true other packets than for REKEY packets.
5254 Affected file silcd/server.c. The same was done to client library
5255 as well, affected file lib/silcclient/client.c.
5257 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5259 * Fixed bug in client and server to accept the force send if
5260 the packet is send from silc_[server/client]_packet_process
5261 function. Otherwise the packets are never delivered, oops.
5263 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5265 * Disable force sending of packets when REKEY protocol is active.
5266 We must assure that no packet is sent directly when rekey is
5267 performed. All packets must be sent through packet queue.
5268 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
5269 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
5270 function is silc_[server/client]_packet_send_real to check
5273 * Replaced the SIM paths from example config files to
5274 /usr/local/modules. Also, make install creates now
5275 /usr/local/silc/logs directory to hold all the SILC server
5278 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5280 * Made the configure.in.pre work on Solaris. Patch by salo.
5282 * Made all ciphers compatible with non-x86 machines. Defined
5283 CBC mode macros into lib/silccrypt/ciphers_def.h.
5285 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5287 * Fixed the make install.
5289 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5291 * When MAC computation fails the silc_packet_decrypt returned 0
5292 even though it was supposed to return -1. Fixed this. The
5293 affected file is lib/silccore/silcpacket.c.
5295 * Do not replace the config files in /etc/silc (in make install)
5296 if they already exist. Affected file ./Makefile.am.
5298 * Do not send re-key packets immediately but through packet queue.
5299 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
5301 * Changed silc_net_check_host_by_sock to return FALSE if the
5302 IP/DNS could not be resolved. Though, it returns the IP address
5303 now even if it could not resolve it (but returns also FALSE).
5304 Affected file lib/silcutil/silcnet.[ch].
5306 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5308 * Added silc_pkcs_decode_identifier to decode the public key's
5309 identifier. Affected file lib/silccrypt/silpkcs.[ch].
5310 Added also silc_pkcs_free_identifier. Added also new context
5311 SilcPublicKeyIdentifier.
5313 * Added -S option to the silc client. It is used to dump the
5314 contents of the specified public key file.
5316 * Changed the PKCS api to return the public key length when
5317 setting the public key.
5319 * Fixed a fatal bug in the public and private key file loading.
5320 Affected file lib/silccrypt/silcpkcs.c.
5322 * Execute the packet parsing for client with zero (0) timeout
5323 if the protocol is active. Affected file silcd/server.c.
5325 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5327 * Made the key generation options to the silcd program. Added
5328 -C option, equivalent to client's option.
5330 * Added new [ServerKeys] config section to the server. It
5331 configures the server's public and private key.
5333 * Defined generic Public Key Payload into the protocol
5334 specification to send specific type of public keys and
5337 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
5338 public key or certificate.
5340 * Implemented the GETKEY command to the server and to the
5341 client library and on user interface.
5343 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5345 * Made preliminary `make install' work.
5347 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5349 * Added SilcServerRekey context into silcd/idlist.h.
5351 * Added the PFS support as defined in the specification to the
5352 SKE protocol. Affected files lib/silcske/*.c.
5354 * Added `ske_group' field to the SilcServerRekey context to hold
5355 the number of the SKE group that is used with PFS in re-key.
5356 Affected file silcd/idlist.h.
5358 * Added PFS re-key support to the server. Affected file is
5361 * Added silc_protocol_cancel to cancel execution of the next
5362 state of the protocol. Affected file is
5363 lib/silccore/silcprotocol.[ch].
5365 * Added the re-key support with and without PFS to the client
5366 library. Re-key is performed once in an hour, by default.
5368 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
5369 Added silc_client_rekey_callback and silc_client_rekey_final.
5370 Affected files are lib/silcclient/protocol.[ch] and
5371 lib/silcclient/client.[ch].
5373 * Removed the `hmac_key' and `hmac_key_len' fields from the
5374 SilcClientConnection structure; not needed. Affected file is
5375 lib/silcclient/client.h.
5379 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5381 * Do not ask whether user wants to use the negotiated private key
5382 for private messages, just use it. Affected file is
5383 silc/local_command.c.
5385 * Added `send_enc_key' and `enc_key_len' fields to the
5386 SilcIDListData structure since they are needed in the re-key
5387 phase. Affected file is silcd/idlist.[ch].
5389 * Implemented the simple re-key protocol into the server.
5390 Affected files silcd/server.c and silcd/protocol.[ch]. The
5391 re-key will be performed once in an hour, by default.
5393 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
5394 Added silc_server_rekey, silc_server_rekey_callback and
5395 silc_server_rekey_final.
5397 * Removed Tunneled flag from the protocol. Updated the code
5398 and the specifications.
5400 * Adde `pfs' field to the SilcIDListData to indicate whether
5401 the PFS is to be performed in the re-key. Affected file is
5404 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5406 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
5407 int64 of at least the xintXX size. If void * is less that 4
5408 bytes uint32 * will be used. Defined bool as boolean.
5410 * Changed _ALL_ unsigned long and unsigned int to uint32,
5411 unsgined short to uint16 in the source tree.
5413 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
5414 not handle clients that has entry->data.registered == FALSE.
5415 They are not in the network anymore. Affected file is
5418 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5420 * Implemented the sending of the SERVER_SIGNOFF notify in the
5421 server. Affected file is silcd/server.c.
5423 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
5424 Added also silc_notify_payload_encode_args into the
5425 lib/silccore/silcnotify.[ch].
5427 * Implemented ther SERVER_SIGNOFF notify handling in the server.
5428 Affected file silcd/packet_receive.c.
5430 * Implemented the SERVER_SIGNOFF notify handling in the client
5431 library. Affected file lib/silcclient/client_notify.c. Also,
5432 implemnted the printing of the SERVER_SIGNOFF info to the
5433 application. Affected file silc/client_ops.c.
5435 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
5436 if the deleting was successful. Affected file silcd/idlist.[ch].
5438 * Added support for public key authentication in the connection
5439 authentication protocol in the client library. Affected file
5440 lib/silcclient/protocol.c.
5442 * Changed the server's silc_idlist_get_clients_by_* interface
5443 to support already allocated array so that new entries may be
5444 added to pre-allocated array. Affected file silcd/idlist.[ch].
5445 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
5446 and command replies.
5448 * All command reply functions in the server now calls the
5449 pending command callback even if error occured. This way the
5450 error will be delivered to the client as well. Affected files
5451 silcd/command.c and silcd/command_reply.c.
5453 * Fixed INFO command to return local server's info if no server
5454 was provided. Affected file lib/silcclient/command.c.
5456 * Removed RESTART command for good. Updated the code and the
5459 * Rewrote parts of the task system. It is a bit simpler now.
5460 Removed unsued task priorities. The affected files are
5461 lib/silcutil/silctask.[ch].
5463 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5465 * Moved the USERS printing from the library to the application.
5466 Affected files lib/silcclient/command.c and silc/client_ops.c.
5468 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5472 * Added channel key re-key support. The re-key is perfomed
5473 only by the router and is done once in an hour. Added `rekey'
5474 field to the SilcChannelEntry in the server. Affected files
5475 silcd/server.c and silcd/idlist.h.
5477 * Added silc_task_unregister_by_context into the file
5478 lib/silcutil/silctask.[ch].
5480 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5482 * Added SILC_UMODE_GONE mode to indicate when the client is not
5483 present in the SILC network. Added also support to the local
5484 command AWAY that will set this mode. Added support of showing
5485 "xxx is gone" in WHOIS command. The USERS command shows the
5486 gone status as well.
5488 * Fixed setting server and router operator privileges in the
5489 server's UMODE command. Affected file silcd/command.c.
5491 * Merged the SKE KE1 and KE2 payloads into one payload. The
5492 new KE payload is equivalent to the old KE2 payload.
5494 Cleaned up the SKE Start Payload parsing. It now uses the
5495 simple buffer unformatting to do the parsing. A lot faster
5498 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
5499 to the SKE that is used to indicate whether both of the SKE
5500 parties should perform authentication. By default only the
5501 responder performs authentication. By setting this flag also
5502 the initiator must do authentication. By default it is unset
5503 since in normal SKE case, client to server connection, only
5504 the responder should do authentication. When doing SKE between
5505 two clients both should perform authentication. Updated the
5506 code and the protocol specs.
5508 * A little fix to IDENTIFY command in the server. Search the
5509 client first by hash not nickname. Affected file is
5512 * Fixed the silc_client_close_connection to support closing
5513 the client to client connections wihtout deleting too much
5514 data. Affected file lib/silcclient/client.c.
5516 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
5517 are received if protocol used to be active but is not anymore
5518 the application would crash due to NULL pointer dereference.
5519 Affected files silcd/server.c and lib/silcclient/client.c.
5521 * Added `hash' field to the SilcClientConnection to include
5522 the hash function negotiated in the SKE protocol.
5524 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
5525 to set the channel founder authentication data. A client can
5526 claim the founder rights later by providing the authentication
5527 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
5528 This way the channel founder can regain the channel founder
5529 privileges even it is left the channel. This works only on
5530 local server and the client must be connected to the same
5531 server to be able to regain the founder rights. Updated the
5532 protocol specs accordingly.
5534 Added support to the CMODE command in the client to set the
5535 founder auth data. Read the README to see how to set it.
5537 Added support to the CUMODE command to claim the founder
5538 rights. Read the README to see how to do it.
5540 Added support for the founder authentication to the Channel
5541 Entry in the server. Affected file silcd/idlist.h.
5543 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
5544 server's CMODE command. Affected file silcd/command.c.
5546 * Added the following new functions into lib/silccore/silcauth.[ch]:
5547 silc_auth_get_method and silc_auth_get_data.
5549 * The server now saves the remote hosts public key to the
5550 SilcIDListData pointer. Affected file silcd/protocol.c.
5552 * The normal server now does not remove the channel entry from
5553 the cache if the founder authentication data is set. It used
5554 to remove it if the founder was the last one on the channel on
5555 the server and left the channel. The auth data is saved and
5556 if the channel is re-joined later the old entry is used with
5557 the old auth data. Affected files silcd/command_reply.c and
5560 * Removed the `pkcs' field from the SilcIDListData structure
5561 in the server; it is not used. Affected file silcd/idlist.h.
5563 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5565 * Fixed packet processing on slow links. Partial packets were
5566 never re-processed because the incoming data buffer was cleared
5567 by the application. Application must not directly clear the
5568 sock->inbuf, the packet processing routines handle it. Fixed
5569 this in client library and in server.
5571 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5573 * Fixed the WHOIS and IDENTIFY send reply function to really
5574 check whether to send list or just one entry. Affected file
5577 * Cleaned up the LEAVE command's channel key distribution. The
5578 affected file silcd/command.c.
5580 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
5581 can enforce the channel mode as well. In that case the ID
5582 includes the ID of the server. The code now enforces the
5583 mode change if the router have different mode than the server.
5585 * The notify client operation with CMODE_CHANGE notify can now
5586 return NULL client_entry pointer if the CMODE was not changed
5587 by client. Application must check for this.
5589 * Added <Server ID> argument to INFO command to support server
5590 info fetching by Server ID.
5592 * Added silc_server_announce_get_channel_users to get assembled
5593 packets of channel users of the specified channel. Affected
5594 file silcd/server.[ch].
5596 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
5597 was freed underneath the ID Cache.
5599 * Re-announce clients when the server received CHANNEL_CHANGE
5600 notify from the router. Affected file silcd/packet_send.c.
5602 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5604 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
5605 crashed since it did not handle the fact that there is no cipher
5606 called "3" and didn't check the error condition. Now fixed.
5608 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
5609 flag. It can be used to send message requests.
5611 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5613 * Implemented the RESTART command in the client.
5615 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
5616 notice type messages. Added notice printing to the user
5619 * The channel keys are not re-generated if the channel's mode
5620 is PRIVKEY, ie private key on the channel exists. Affected
5621 files silcd/server.c and silcd/command.c.
5623 * Fixed a little bug in channel message delivery when channel
5624 private keys are set in the server. Affected file is
5625 silcd/packet_send.c.
5627 * Changed the setting on channel->on_channel = TRUE from the
5628 silc_client_save_channel_key to the JOIN command reply. The
5629 key payload is not received if the private channel key is set.
5630 Affected file lib/silcclient/command_reply.c and the
5631 lib/silcclient/client_channel.c.
5633 * When the CMODE_CHANGE notify is sent and the channel private
5634 key mode is removed the channel key must be re-generated in
5635 other cells as well. Added this support for the router in the
5636 silcd/packet_receive.c.
5638 * Added new local command NOTICE to send notice message on
5639 channel. Affected file silc/local_command.[ch].
5641 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5643 * Added new local command ME to the client. It is used to send
5644 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
5645 some action. Affected file silc/local_command.[ch].
5647 * Changed channel_message and private_message client operations
5648 to deliver the message flags to the application. Added also
5649 the `flags' arguments to the silc_client_send_channel_message
5650 and silc_client_send_private_message functions. Affected file
5653 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5655 * Redefined the Private Message Payload to support private message
5656 keys and to support the new private message flags. Updated
5657 the protocol specs. Flags makes it possible to have for example
5658 CTCP style messages.
5660 * Added new type SilcPrivateMessagePayload and defined an API
5661 for it in the lib/silcclient/silcprivate.[ch].
5663 * Tested private message private keys successfully. Tested the
5664 private message key set, unset and list commands with the new
5667 * Redefined the Channel Message Payload to include the channel
5668 message flags (equal with private message flags) to support
5669 for example CTCP style messages.
5671 * Defined some of the message (for channel and private message)
5672 flags. Updated the protocol specs and added the flags to the
5673 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5675 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5677 * Added SilcKeyAgreementStatus type to the key agreement routines
5678 to indicate the current status and error if one occured.
5679 The status types are defined in the lib/silcclient/silcapi.h.
5681 * Added new local command KEY that is used to set and unset private
5682 keys for channels, set and unset private keys for private messages
5683 with remote clients and to send key agreement requests and
5684 negotiate the key agreement protocol with remote client. The
5685 key agreement is supported only to negotiate private message keys,
5686 it currently cannot be used to negotiate private keys for channels,
5687 as it is not convenient for that purpose.
5689 * Fixed a minor pending callback setting bug in the function
5690 silc_client_get_client_by_id_resolve, now the function works.
5691 Affected file lib/silcclient/idlist.c.
5693 * Added function silc_net_get_local_port to get local bound
5694 port by socket. Added to lib/silcutil/silcnet.[ch].
5696 * Added `sockets' and `sockets_count' fields to the SilcClient
5697 object. They hold the sockets of the listenning sockets in
5698 the client. Listenning sockets may be for example the key
5699 agreement server. Affected file lib/silcclient/client.[ch].
5700 Added functions the silc_client_add_socket and the
5701 silc_client_del_socket. They are exported to the application
5704 * Added ~./silc/clientkeys to support other client's public keys.
5706 * Renamed verify_server_key client operation to verify_public_key
5707 and added one argument to indicate the type of the connection
5708 (server, client etc.).
5710 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5712 * Added silc_server_connection_auth_request to handle the
5713 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5714 silcd/packet_receive.[ch].
5716 * Added silc_server_send_connection_auth_request into the
5717 silcd/packet_send.c to send the connection auth request packet.
5719 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5722 * Fixed the public key authentication in responder side in the
5723 server. The `auth_data' pointer includes the SilcPublicKey
5724 not the path to the public key. Affected file silcd/protocol.c.
5726 * Implemented the public key authentication in the initiator side
5727 in the server. Affected file silcd/protocol.c.
5729 * Removed the [RedirectClient] config section from the server
5730 configuration. Is not needed and I don't want to implement it.
5732 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5734 * Cleaned up the CMODE command in the server. It now works
5735 correctly and supports all the modes defined in the protocol.
5736 Affected file is silcd/command.c.
5738 * Added `hmac_name' field to the SilcChannelEntry in the server
5739 to hold the default HMAC of the channel. It can be set when
5740 creating the channel (with JOIN command). Affected files
5743 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5744 type to indicate the change of the current cipher and hmac
5745 on the channel. Client can safely ignore the <cipher> argument
5746 (if it chooses to do so) since the CHANNEL_KEY packet will
5747 force the channel key change anyway. The <hmac> argument is
5748 important since the client is responsible of setting the new
5749 HMAC and the hmac key into use.
5751 * Fixed the CMODE command in the client library as well.
5753 * Tested CMODE command in router environment successfully.
5755 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5757 * Show the version of the remote client (or server) when connecting
5758 to the server. It is logged to the log file. Affected file
5759 is silcd/protocol.c.
5761 * Fixed the KILLED notify handling in the client library. The
5762 client must be removed from all channels when receiving the
5765 Also, do not remove the client entry when giving the KILL
5766 command but when the KILLED notify is received.
5768 * Removed silc_idlist_find_client_by_nickname from the server.
5769 Not needed anymore. Affected files silcd/idlist.[ch].
5771 * Implemented the CHANNEL_CHANGE notify type handling to the
5772 server. Affected file silcd/server.c.
5776 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

5779 notify between routers.
5781 * Implemented the INVITE command correctly to the server.
5783 * Implemented the INVITE notify type handling in the server.
5785 * Implemented the INVITE command to the client library and on the
5788 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5790 * Added function silc_server_get_client_resolve to find the
5791 client entry by ID from all ID lists and then resolve it
5792 (using WHOIS) if it cannot be found. Affected file is
5795 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5797 * Implemented the BAN command to the client library.
5799 * The JOIN command in the server now checks the invite list
5802 * Changed the silc_command_reply_payload_encode_va and the
5803 silc_command_payload_encode_va to support that if argument is
5804 NULL it ignores and checks the next argument. Affected file
5805 lib/silccore/silccommand.c.
5807 * Added silc_server_send_notify_ban to send the BAN notify
5808 type between routers.
5810 * Chaned the silc_notify_payload_encode to support that if
5811 argument is NULL it ignores and checks the next argument.
5812 Affected file lib/silccore/silcnotify.c.
5814 * Tested ban lists in router environment successfully.
5816 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5818 * Implemented BAN command to the server, in silcd/command.[ch].
5820 * Removed the BAN and INVITE_LIST modes from the CMODE command
5823 * Added function silc_string_match to regex match two strings.
5824 Affected files lib/silcutil/silcutil.[ch].
5826 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5828 * Redefined parts of the SilcChannelEntry in the server to support
5829 the new ban and invite lists.
5831 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5833 * Redefined the INVITE command. The same command can be used to
5834 invite individuals to the channel but also to manage the invite
5835 list of the channel (to add to and remove from the invite list).
5836 Updated the protocol specs.
5838 * Added new command SILC_COMMAND_BAN that can be used to manage
5839 the ban list of the channel. Updated the protocol specs.
5841 * Removed the channel modes: the SILC_CMODE_BAN and the
5842 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5843 in the CMODE command. The equivalent features are now available
5844 using INVITE and BAN commands. Updated the protocol specs.
5846 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5847 in the network about change in the current ban list. The notify
5848 type is not used by the client.
5850 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5851 support the invite lists.
5853 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5855 * Added new function silc_string_regexify that converts string
5856 including wildcard characters into regex string that can
5857 be used by the GNU regex library. Added into the file
5858 lib/silcutil/silcutil.[ch].
5860 Added silc_string_regex_combine to combine to regex strings
5861 into one so that they can be used as one regex string by
5862 the GNU regex library. Added into the file
5863 lib/silcutil/silcutil.[ch].
5865 Added silc_string_regex_match to match two strings. It returns
5866 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5868 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5870 * Imported GNU regex to the soruce tree into lib/contrib.
5871 Fixed some compiler warning from the regex.c.
5873 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5875 * Fixed MOTD command in the server to work in router environment.
5877 * Fixed the MOTD command in the client library to support
5878 the server argument in the command.
5880 * Added `nickname_len' argument to the silc_idlist_add_client
5881 in the server, as the `nickname' argument may be binary data
5884 * Added silc_idlist_get_channels to return all channels from
5887 * Implemented LIST command to the server. Affected file is
5890 * Implemented the LIST command to the client library and on the
5893 * Added [<user count>] argument to the LIST command reply.
5894 With private channels the user count is not shown.
5896 * Updated TODO and README.
5898 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5900 * The client entry's data.registered must be TRUE even with
5901 global client entry on global client list. The data.registered
5902 is used to check whether the client is anymore in the network,
5903 for example with WHOWAS command so it must be valid.
5905 * Fixed the WHOWAS command in the server. It now actually works
5906 in router environment. Added function into silcd/command_reply.c
5907 silc_server_command_reply_whowas_save.
5909 * Added silc_idlist_purge function to the silcd/idlist.c
5910 to periodically purge the ID Cache.
5912 * Fixed INFO command in the server. It works now in router
5913 environment. Added <server name> argument to the INFO command
5914 reply. Updated the protocol specs.
5916 * Fixed minor bug in silc_idcache_purge to not purge if the
5917 expire value is zero.
5919 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5920 they were buggy because of the WHOWAS information.
5922 * Fixed local command MSG to handle the async resolving of
5923 the remote client properly. It used to fail the first MSG.
5924 Affected file silc/local_command.c.
5926 * Added `data_len' field to SilcIDCache context.
5928 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5930 * Update TODO. Todo in commands in the server.
5932 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5934 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5935 used by routers as broadcast packet to inform other routers
5936 about the changed user mode.
5938 Implemented the notify handling in the server. Affected file is
5939 silcd/packet_receive.c. Added the function
5940 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5942 * Added new generic Channel Payload and deprecated the New Channel
5943 Payload. The New Channel Payload is now the generic Channel
5946 * Added new argument `mode' to the silc_server_send_new_channel
5947 as it is required in the Channel Payload now.
5949 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5950 and created a new and real SilChannelPayload to represent the
5951 new generic Channel Payload. Implemented the encode/decode
5952 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5954 * Added silc_server_get_client_channel_list to return the list
5955 of channels the client has joined for WHOIS command reply.
5956 Affected file silcd/server.[ch].
5958 * Implemented the channel list sending in the WHOIS command reply
5959 in server and in the client.
5961 Implemented the channel list displaying on the user interface
5962 as well. Affected file silc/client_ops.c.
5964 * Added silc_channel_payload_parse_list to parse list of Channel
5965 Payloads. It returns SilcDList list of SilcChannelPayloads.
5966 Client for example can use this function to parse the list of
5967 channels it receives in the WHOIS command reply. The caller
5968 must free the list by calling silc_channel_payload_list_free.
5969 Affected files lib/silccore/silcchannel.[ch].
5971 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5973 * Added one new argument <user mode> to the WHOIS command reply
5974 to return the mode of the user in SILC. Updated the protocol
5977 Implemented it to the server and client.
5979 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5981 * Fixed the mode printing on the user interface on joining.
5982 Affected file silc/client_ops.c.
5984 * Implemented the UMODE command and user modes in general to the
5985 client library and to the user interface.
5987 * Implemented the UMODE command to the server.
5989 * The server now sends UNKNOWN_COMMAND error status if client sends
5990 unknown command. Affected file silcd/command.c.
5992 * All server commands now handle the command identifier the right
5993 way when sending the command reply to the client. The client can
5994 use to identify the command replies with the identifier.
5996 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5998 * Added silc_server_get_client_route to resolve the route to
5999 the client indicated by the client ID. Affected file is
6002 * Added silc_server_relay_packet as general function to relay
6003 packet to arbitrary destination. This deprecates functions
6004 like _send_private_message_key, _relay_notify etc. Affected
6005 file is silcd/packet_send.[ch].
6007 Removed silc_server_send_key_agreement,
6008 silc_server_send_private_message_key and
6009 silc_server_packet_relay_notify functions from the file
6010 silcd/packet_send.[ch].
6014 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
6015 server. Affected file silcd/packet_receive.[ch].
6017 * Implemented the KILL command to the client. Implemented the
6018 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
6019 Affected files lib/silcclient/command[_reply].c and
6020 lib/silcclient/client_notify.c. Implemented the KILL notify
6021 printing in the user inteface.
6023 * Fixed a lot silc_parse_nick memory leaks from the client
6024 library in the file lib/silcclient/command.c.
6026 * Changed the silc_server_send_notify_on_channels's `sender'
6027 argument from SilcSocketConnection to SilcClientEntry to
6028 check the sender as entry and not as connection object and not
6029 to send to the client provided as argument. The affected file
6030 is silcd/packet_send.[ch].
6032 * The notify packets that are destined directly to the client used
6033 to not to be processed by the server. Now changed that and the
6034 server processes all notify packets. After relaying the packet
6035 to the client the notify packet is processed in the server.
6037 * The silc_server_free_client_data now checks whether there is
6038 pending outgoing traffic for the client and purges the data to
6039 the network before removing the client entry.
6041 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6043 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
6044 an client is killed from the SILC Network. Updated the protocol
6047 Added new function silc_server_send_notify_killed to the
6048 silcd/packet_send.[ch].
6050 * Added function silc_server_packet_relay_notify to relay notify
6051 packets that are destined directly to a client. In this case
6052 the server does not process the notify packets but merely relays
6053 it to the client. Affected file silcd/packet_send.[ch].
6055 Added also silc_server_packet_process_relay_notify to check
6056 whereto relay the notify. Affected file is
6057 silcd/packet_receive.[ch].
6059 * Implemented the KILL command to the server.
6063 * Added the backup schema desgined last fall to the protocol
6064 specs for everyone to see. The specification is in the
6065 *-spec-xx.txt draft and the packet type definitions for the
6066 backup routers is in *-pp-xx.txt draft. Thusly, added also
6067 new packet type SILC_PACKET_CELL_ROUTERS.
6069 * A big security problem in the implementation discovered. The
6070 signoff of an client did not cause new channel key generation
6071 which it of course should've done. The channel keys must be
6072 always re-generated when client leaves (or signoffs) the channel.
6073 The silc_server_remove_from_channels funtion now handles
6074 the channel key re-generation.
6076 * Added `sender' argument to the silc_server_send_notify_on_channels
6077 to not to send the client provided as argument. Affected file
6078 silcd/packet_send.[ch].
6080 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6082 * Implemented OPER and SILCOPER commands into the server and
6085 * Added silc_auth_verify and silc_auth_verify_data to verify
6086 the authentication directly from the authentication payload.
6087 It supports verifying both passphrase and public key based
6088 authentication. Affected file lib/silccore/silcauth.[ch].
6090 * Added `hash' field to the SilcIDListData structure. It is the
6091 hash negotiated in the SKE protocol. Affected file is
6094 * Slight redesigning of the SilcAuthPayload handling routines.
6095 Do not send SilcPKCS but SilcPublicKey as argument.
6097 * Implemented the public key authentication support to the
6098 serverconfig. The public key is loaded from the provided path
6099 and saved as authentication data to void * pointer. Thus,
6100 changed the unsigned char *auth_data to void *auth_data;
6102 * Fixed SHUTDOWN command to send the reply before the server
6103 is shutdown. :) Affected file silcd/command.c.
6105 * Fixed fatal bug in CONNECT command. The hostname was invalid
6106 memory and server crashed. Affected file silcd/command.c.
6108 * Fixed fatal bug in CLOSE command. The server_entry became
6109 invalid but was referenced later in the command. Affected file
6112 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6114 * Fixed fatal bug in failure packet handling. Server ignored
6115 the failure and thus crashed when it came.
6119 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6121 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
6122 that the command may be executed only once in (about) 2 seconds.
6123 The old SILC_CF_LAG flag is same but allows command bursts up
6124 to five before limiting.
6126 Added the support for CF_LAG and CF_LAG_STRICT flags to the
6127 server code. Various commands now includes the CF_LAG_STRICT
6128 flag to disallow any kind of miss-use of the command.
6130 * Fixed the silc_buffer_unformat to not to allocate any data
6131 if the length of the data is zero. It used to allocate the
6132 length + 1. Affected file lib/silcutil/silcbuffmt.c.
6134 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6136 * Changed the format of AdminConnection configuration section
6137 in the server. Added username of the admin to the format.
6138 Affected files silcd/serverconfig.[ch].
6140 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
6141 to return admin configuration data by host, username and/or
6144 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6146 * Implemented WHOWAS command to the server. Added the functions:
6148 silc_server_command_whowas_parse,
6149 silc_server_command_whowas_send_reply,
6150 silc_server_command_whowas_from_client and
6151 silc_server_command_whowas_from_server
6153 * Added <Client ID> argument to the WHOWAS command reply. Updated
6154 the protocol specs accordingly.
6156 * Implemented WHOWAS command and command_reply to the client
6159 Implemented the WHOWAS printing on the user interface.
6161 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6163 * Added new argument to the WHOWAS command reply, the real name.
6164 It is an optional argument. Updated the protocol specs.
6166 * Added SilcIDCacheDestructor callback that is registered when
6167 the SilcIDCache is allocated. The callback is called when
6168 an cache entry in the ID Cache expires, or is purged from the
6169 cache. Added into lib/silccore/idcache.[ch].
6171 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
6172 to destruct the client entries when the cache entry expires.
6173 Other ID Cache's in server and in the client library ignores
6176 * If the ID Cache entry's `expire' field is zero then the entry
6177 never expires. Added boolean `expire' argument to the
6178 silc_idcache_add function in the lib/silccore/idcache.[ch].
6179 If it is TRUE the default expiry value is used.
6181 * Added silc_server_free_client_data_timeout that is registered
6182 when client disconnects. By default for 5 minutes we preserve
6183 the client entry for history - for WHOWAS command.
6185 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6187 * Added support to the server to enforce that commands are not
6188 executed more than once in 2 seconds. If server receives
6189 commands from client more frequently, timeout is registered
6190 to process the commands. Affected file silcd/command.c.
6191 Added new function silc_server_command_process_timeout.
6193 * Changed NICK_NOTIFY handling in client library to check that
6194 if the client's nickname was changed, so there is no need to
6195 resolve anything from the server.
6197 * Removed error printing from the WHOIS and IDENTIFY commands.
6198 If error occurs then it is ignored silently in the client library.
6199 The application, however, may map the received error to
6200 human readable error string. The application currently maps
6201 the NO_SUCH_NICKNAME error to string.
6203 * Made the command status message public to the application. Moved
6204 them from lib/silcclient/command_reply.c to
6205 lib/silcclient/command_reply.h. The application can map the
6206 received command status to the string with the
6207 silc_client_command_status_message function.
6209 * Added check to the server to check that client's ID is same
6210 as the Source ID in the packet the client sent. They must
6213 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6215 * Added dist-bzip hook to the Makefile.am to make bzip2
6216 compressed distributions.
6218 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6220 * Server now enforces the maximum length for the nickname and
6221 the channel as protocol specification dictates. 128 bytes for
6222 nickname and 256 bytes for channel name.
6224 * Moved the WHOIS printing to the application. The client libary
6225 does not print out the WHOIS information anymore, the application
6226 must do it. Renamed silc_client_command_reply_whois_print to
6227 the silc_client_command_reply_whois_save.
6229 The client's idle time is also sent to the application now, and
6230 the idle is shown on screen.
6232 * Added silc_client_command_reply_identify_save to save the
6233 received IDENTIFY entries.
6235 * Do not check for channel private keys in message sending and
6236 reception if the channel does not have the PRIVKEY mode set.
6237 Affected file lib/silclient/client_channel.c.
6239 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6241 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
6242 just surfaced after chaning the JOIN procedure.
6244 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6246 * Added silc_client_get_clients_by_list to get client entries
6247 from Client ID list, that is returned for example by JOIN
6248 and USERS command replies. The application should use this
6249 function for example when JOIN command reply is received to
6250 resolve the clients already on the channel (library does not
6251 do that anymore as USERS command reply is not used in the JOIN
6252 procedure anymore). Affected files lib/silcclient/silcapi.h and
6253 lib/silcclient/idlist.c.
6255 * JOIN command reply and USERS command reply returns now SilcBuffer
6256 pointers instead of unsigned char pointers when returning
6257 the client list and mode list.
6259 * Added <Client ID> argument to the JOIN command reply, mainly
6260 for the server to identify for which client the command was
6261 originally sent. Updated protocol specs accordingly.
6263 * Added SilcDlist private_key pointer to the SilcChannelEntry
6264 in the client to support the channel private keys. Affected
6265 file is lib/silcclient/idlist.h.
6267 * Added SilcChannelPrivateKey argument to the function
6268 silc_client_send_channel_message so that application can choose
6269 to use specific private ke if it wants to. If it is not provided,
6270 the normal channel key is used, unless private keys are set.
6271 In this case the first (key that was added first) is used
6272 as the encryption key.
6274 * Implemented the support for channel private key handling.
6275 Implemented the following functions:
6277 silc_client_add_channel_private_key,
6278 silc_client_del_channel_private_keys,
6279 silc_client_del_channel_private_key,
6280 silc_client_list_channel_private_keys and
6281 silc_client_free_channel_private_keys
6283 Affected file lib/silcclient/client_channel.c.
6285 * Added the support for the private keys in the channel message
6286 sending and encryption and in the message reception and
6287 decryption. Affected funtions are
6288 silc_client_send_channel_message and silc_client_channel_message.
6290 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6292 * Added SKE's key verify callback to the client library's
6293 KE protocol context. Affected files lib/silcclient/protocol.[ch].
6295 * Removed the statement that server (or router) must send USERS
6296 command reply when joining to the channel so that the client
6297 knows who are on the channel. Instead, the client list and
6298 client's mode list is now sent in the JOIN command reply to the
6299 client who joined channel. This is better solution.
6301 * Added function silc_server_get_users_on_channel and function
6302 silc_server_save_users_on_channel to the silcd/server.[ch].
6304 * Removed function silc_server_command_send_users from the
6307 * Do not show topic on the client library anymore. The topic is
6308 sent in the command reply notify to the application and the
6309 application must show the topic now.
6311 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6313 * Added client searching by nickname hash into the IDENTIFY and
6314 WHOIS commands in the server as they were clearly missing from
6315 them. Affected file is silcd/command.c.
6317 * Fixed a bug in private message receiving in the client library.
6318 The remote ID was freed and it wasn't supposed, now it is
6321 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6323 * Minor fix to the channel payload; allocate the data area, as it
6324 needs to be of specific length.
6326 * If the key agreement port is zero then the operating
6327 system will define the bound port. Affected files are
6328 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
6330 * Added new function silc_channel_payload_decrypt into the file
6331 lib/silccore/silcchannel.[ch].
6333 * Moved the channel message etc, check from silc_packet_decrypt
6334 to applications. The library calls now a generic
6335 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
6336 when the packet is either normal or special. This was done to
6337 allow more wide range of checking that was not allowed when
6338 the code was in library. Now applications can do virtually any
6339 checks to the packet and return to the library the decision how
6340 the packet should be processed. Affected files are
6341 lib/silccore/silcpacket.[ch].
6343 Added silc_server_packet_decrypt_check to the server and
6344 silc_client_packet_decrypt_check to the client library.
6346 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
6347 to send with specified source and destination information.
6349 * Channel message delivery between routers was broken after the
6350 channel key distribution was fixed earlier. The channel key
6351 was used be to distributed to other routers as well which is not
6352 allowed by the protocol. Now this is fixed and channel keys
6353 really are cell specific and the channel message delivery between
6354 routers comply with the protocol specification.
6356 * Fixed various commands in server to check also the global list
6357 for the channel entry and not just the local list. The affected
6358 file silcd/command.c.
6360 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6362 * Added assert()s to buffer formatting and unformatting routines
6363 to assert (if --enable-debug) when error occurs. Affected
6364 file: lib/silcutil/silcbuffmt.c.
6366 * Changed to auto-reconnect to check whether the remote host is
6367 router and register the re-connect timeout if it is. It used
6368 to check that whether we are normal server, but router must do
6369 auto-reconnect with another router as well. Affected file
6372 * Removed the [<key len>] option from CMODE command as the cipher
6373 name decides the key length, nowadays. See the defined ciphers
6374 from the protocol specification.
6376 * Added [<hmac>] option to the CMODE command to define the HMAC
6377 for the channel. Added SILC_CMODE_HMAC channel mode.
6379 * Added [<hmac>] option for the JOIN command so that user can
6380 select which HMAC is used to compute the MACs of the channel
6383 * Added Hmac field to the Channel Message Payload. The integrity
6384 of plaintext channel messages are now protected by computing
6385 MAC of the message and attaching the MAC to the payload. The
6386 MAC is encrypted. Now, it is clear that this causes some
6387 overhead to the size of the packet but rationale for this is that
6388 now the receiver can verify whether the channel message decrypted
6389 correctly and also when private keys are set for the channel the
6390 receiver can decrypt the packet with several keys and check from
6391 the MAC which key decrypted the message correctly.
6393 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
6394 lib/silccrypt/silccipher.[ch].
6396 * Added silc_hash_len to return the digest length into the
6397 lib/silcrypt/silchash.[ch].
6399 * Rewrote parts of Silc Channel Payload interface in the
6400 lib/silccore/silcchannel.[ch]. The encode function now also
6401 encrypts the packet and parse function decrypts it.
6403 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6405 * Fixed a minor formatting bug in the SKE's key material processing.
6406 It actually might have processed the keys wrong way resulting
6409 * Redefined the mandatory HMAC algorithms and added new algorithms.
6410 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
6411 and hmac-md5 truncated to 96 bits. The mandatory is now
6412 hmac-sha1-96. Rest are optional (including the one that used
6413 to be mandatory). Rationale for this is that the truncated HMAC
6414 length is sufficient from security point of view and can actually
6415 make the attack against the HMAC harder. Also, the truncated
6416 HMAC causes less overhead to the packets. See the RFC2104 for
6419 * Added new [hmac] configuration section. The SKE used to use
6420 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
6421 is of course wrong. The official names that must be proposed in
6422 the SKE are the ones defined in the protocol specification
6423 (hmac-sha1-96 for example). The user can configure any hmac
6424 using any hash function configured in the [hash] section. At
6425 least, the mandatory must be configured.
6427 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
6429 * Added HMAC list to the SKE proposal list. It has now both
6430 hash algorithm list and HMAC list. This makes the protocol
6431 incompatible with previous versions. The SKE now seems to work
6432 the way it is supposed to work, for the first time actually.
6434 * Defined plain Hash algorithms to the protocol specification.
6437 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6439 * Implemented support for key agreement packets into the server.
6440 Added functions silc_server_key_agreement and
6441 silc_server_send_key_agreement. Other than these functions,
6442 server has nothing to do with this packet.
6444 * Added support for private message key packets into the server.
6445 Added functions silc_server_private_message_key and
6446 silc_server_send_private_message_key.
6450 * Changed the silc_[client|server]_protocol_ke_set_keys to be
6451 called in the protocol's final callback instead in the END
6452 protocol state. This makes a little more sense and in the same
6453 time in client we can use the same protocol routines for normal
6454 key exchange and to key agreement packet handling as well.
6456 * Added to both client's and server's KE protocol context the
6457 SilcSKEKeyMaterial pointer to save the key material. We will
6458 bring the key material to the protocol's final callback by doing
6459 this. The final callback must free the key material.
6461 * Added SKE's packet_send callback into client's KE protocol
6462 context so that the caller can choose what packet sending function
6463 is used. This way we can use different packet sending when
6464 doing normal SKE when doing key agreement packet handling (in
6465 the key agreement packet handling we do not want to encrypt
6468 * Implemented the responder side of the key agreement routines
6469 in the client. The client can now bind to specified port and
6470 accept incoming key negotiation. The key material is passed
6471 to the application after the protocol is over.
6473 * Implemented the processing of incoming Key Agreement packet
6474 in the client. Added function silc_client_key_agreement to
6477 * Implemented the intiator side of the key agreement routines
6478 in the client. The client can now initiate key agreement with
6479 another remote client. The key material is passed to the
6480 application after the protocol is over.
6482 * Created client_keyagr.c to include all the key agreement
6485 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
6486 SILC_TASK_CALLBACK except that it is not static.
6488 * Created client_notify.c and moved the Notify packet handling
6489 from the client.[ch] into that file.
6491 * Created client_prvmsg.c and moved all private message and
6492 private message key routines from the client.[ch] into that file.
6494 * Create client_channel.c and moved all channel message and
6495 channel private key routines from the client.[ch] into that file.
6497 * Changed silc_client_get_client_by_id_resolve to resolve with
6498 WHOIS command instead of IDENTIFY command, in the file
6499 lib/silclient/idlist.c.
6501 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6503 * Implemented the SKE's responder side to the Client library.
6505 * When FAILURE is received to the protocol do not trust it
6506 blindly. Register a timeout to wait whether the remote closes
6507 the connection as it should do it, only after that process the
6508 actual failure. This was changed to both client and server.
6510 * Added client_internal.h to include some of the structures
6511 there instead of client.h in lib/silcclient/.
6513 * Added function silc_task_unregister_by_callback to unregister
6514 timeouts by the callback function.
6516 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6518 * Some "Incomplete WHOIS info" errors has been appearing on the
6519 log files. Took away the entry->userinfo check from WHOIS
6520 reply sending. The entry->userinfo is now " " if client did not
6521 provide one. I thought this was fixed earlier but something
6522 is wrong still. Let's see if the error still appears.
6524 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6526 * Fixed a minor bug in the login when the channel key is
6527 re-generated in the server. It used to generate the key in
6528 wrong order and thus caused problems in the channel traffic.
6530 * Fixed a minor bug in channel key distsribution after
6531 KICK command. The key was not sent to the router even though
6534 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6536 * Added silc_ske_process_key_material_data as generic routine
6537 to process any key material as the SILC protocol dictates. The
6538 function is used by the actual SKE library but can be used by
6539 applications as well. This relates to the private message keys
6540 and the channel private keys since they must be processed the
6541 same way the normal SILC session keys. The protocol dictates
6542 this. Affected files: lib/silcske/silcske.[ch].
6544 Added also silc_ske_free_key_material to free the
6545 SilcSKEKeyMaterial structure.
6547 * Defined silc_cipher_set_key function to set the key for
6548 cipher without using the object's method function. The affected
6549 files: lib/silccrypt/silccipher.[ch].
6551 * Implemented silc silc_client_add_private_message_key,
6552 silc_client_add_private_message_key_ske,
6553 silc_client_del_private_message_key,
6554 silc_client_list_private_message_keys and
6555 silc_client_free_private_message_keys functions in the
6558 Added functions silc_client_send_private_message_key to send
6559 the Private Message Key payload and silc_client_private_message_key
6560 to handle incoming Private Message Key payload.
6562 * Added Cipher field to the Private Message Key payload to set
6563 the cipher to be used. If ignored, the default cipher defined
6564 in the SILC protocol (aes-256-cbc) is used.
6566 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6568 * Removed lib/silcclient/ops.h file.
6570 Redefined parts of the SILC Client Library API. Created new
6571 file silcapi.h that deprecates the ops.h file and defines the
6572 published Client Library API. Defined also private message key
6573 API and channel private key API into the file.
6575 This is the file that the application must include from the
6576 SILC Client Library. Other files need not be included by
6577 the application anymore.
6579 * Added new key_agreement client operation callback and also
6580 defined the Key Agreement library API for the application.
6582 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6584 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
6585 is used by clients to request key negotiation between another
6586 client in the SILC network. If the negotiation is started it
6587 is performed using the SKE protocol. The result of the
6588 negotiation, the secret key material, can be used for example
6589 as private message key.
6591 Implemented the Key Agreement payload into the files
6592 lib/silccore/silauth.[ch].
6594 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6596 * Redefined ciphers for the SILC protocol. Added some new ciphers
6597 and defined the key lengths for the algorithms. Changed the
6598 code accordingly. The default key length is now 256 bits.
6600 * Fixed SKE key distribution function silc_ske_process_key_material
6601 when the key length is more than 128 bits. The default key
6602 length in SILC is now 256 bits.
6604 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
6605 to indicate unsupported algorithm.
6607 * Renamed rijndael.c to aes.c and all functions as well.
6609 * Fixed a long standing channel key setting bug in client library.
6610 Weird that it has never surfaced before.
6612 * Fixed bug in channel deletion. If the entire channel is removed
6613 then it must also delete the references of the channel entry
6614 from the client's channel list as the client's channel entry and
6615 the channel's client entry share same memory.
6617 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6619 * Implemented CONNECT and SHUTDOWN commands in the client.
6621 * Implemented CLOSE command to the client.
6623 * Added the function silc_idlist_find_server_by_name into the
6624 files silcd/idlist.[ch].
6626 Added the function silc_idlist_find_server_by_conn into the
6627 files silcd/idlist.[ch].
6629 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6631 * DIE command was renamed to SHUTDOWN. Updated the both code
6634 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
6635 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
6637 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
6640 * Added function silc_server_create_connection function to create
6641 connection to remote router. My server implementation actually
6642 does not allow router to connect to normal server (it expects
6643 that normal server always initiates the connection to the router)
6644 so the CONNECT command is only good for connecting to another
6647 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6649 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
6650 or some other client was kicked from the channel.
6652 Implemented the handling of the notify type to both client
6655 Implemented silc_server_send_notify_kicked to send the KICKED
6656 notify. It is used to send it to the server's primary router.
6658 * Implemented the KICK command into server and client.
6660 * Added `query' argument to the silc_idlist_get_client function
6661 to indicate whether to query the client from server or not if
6664 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
6665 to indicate that the client is not channel founder.
6669 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6671 * Removed the rng context from SilcPacketContext structure and
6672 changed that the packet routine uses the Global RNG API.
6674 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6676 * Added support for quit message that client can "leave" on the
6677 channel when it quits the SILC. It is ditributed inside the
6678 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6680 Added silc_server_free_client_data that will take the
6681 signoff message as argument.
6683 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6685 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6687 * Updated parts of the protocol specification to keep it up
6690 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6692 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6693 payloads in one packet.
6695 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6696 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6697 use now the new List flag.
6699 * Also deprecated the following packet types: REPLACE_ID,
6700 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6702 * Added list support for Notify packet in server.
6704 * Added silc_server_send_notify_channel_change to send the
6705 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6706 the silc_server_send_replace_id.
6708 * Added silc_server_send_notify_nick_change to send the
6709 NICK_CHANGE notify type. Deprecates the function
6710 silc_server_send_replace_id.
6712 * Added silc_server_send_notify_join to send the JOIN notify type.
6713 Deprecates the function silc_server_send_new_channel_user.
6715 * Added silc_server_send_notify_leave to send LEAVE notify type.
6716 Deprecates the function silc_server_send_remove_channel_user.
6718 * Added silc_server_send_notify_cmode and
6719 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6720 types. Deprecates the silc_server_send_set_mode function.
6722 * Added SERVER_SIGNOFF notify type to indicate that server has
6723 quit. This means that all clients on the channel from that
6724 server will drop. This can be also used when netsplit happens.
6726 Deprecated REMOVE_ID packet type since it is not needed anymore
6729 Added silc_server_send_notify_server_signoff to send the
6730 SERVER_SIGNOFF notify type. Deprecates the function
6731 silc_server_send_remove_id.
6733 Added also silc_server_send_notify_signoff to send the
6734 SIGNOFF notify type.
6736 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6737 SILC protocol from this day on. Changed the protocol
6738 specification as well.
6740 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6741 notify type. It is used between routers to notify about
6742 topic changes on a channel.
6744 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6747 * Partly updated the protocol specification to comply with the
6748 changes now made. It is still though a bit outdated.
6750 * The JOIN notify type now takes one extra argument <Channel ID>.
6751 The packet used to be destined to the channel but now the
6752 JOIN type may be sent as list thus it is impossible to
6753 destine it to any specific channel. By adding this argument
6754 it is again possible.
6756 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6758 * Added CREDITS file. The CHANGES and CREDITS file will appear
6759 in the distribution as well.
6761 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6763 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6764 types in the server's silcd/packet_receive.c.
6766 * Implemented CMODE and CUMODE to work in router environment.
6768 * Fixed minor encoding and decoding buglet from the
6769 lib/silccore/silcmode.c.
6771 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6774 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6776 * Changed all SilcConfigServer* and silc_config_server* to
6777 SilcServerConfig* and silc_server_config*, respectively.
6780 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6782 * Associated the ID (client or server ID) to the Authentication
6783 Payload to avoid any possibility of forging. Updated the
6784 protocol specification and the code accordingly.
6786 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6788 * The RSA key length is now save to the RsaKey context in the
6789 key generation process in lib/silccrypt/rsa.c. The key length
6790 is now used to figure out the maximum size of the block allowed
6791 to be encrypted/signed.
6793 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6794 is equivalent to the silc_mp_mp2bin but does not allocate any
6797 * Changed silc_mp_mp2bin API to take length argument. If it is
6798 non-zero then the buffer is allocated that large. If zero, then
6799 the size is approximated using silc_mp_sizeinbase, which however
6802 * Created Global RNG API which is global RNG that application can
6803 initialize. After initializing, any routine anywhere in the
6804 code (including library) can use RNG without allocating a new
6805 RNG object. This was done to allow this sort of use of the
6806 RNG in code that has no chance to allocate RNG object. All
6807 applications currently allocate this and many routines in the
6808 library use this. Affected file lib/silccrypt/silcrng.[ch].
6810 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6811 it to use the Global RNG API.
6813 * Defined Authentication Payload into protocol specification that
6814 is used during SILC session to authenticate entities. It is
6815 used for example by client to authenticate itself to the server
6816 to obtain server operator privileges.
6818 Implemented this payload into the lib/silccore/silcauth.[ch].
6819 Implemented also routines for public key based authentication
6820 as the new protocol specification dictates.
6822 Moved definitions of different authentication methods from
6823 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6825 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6826 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6827 silc_pkcs_verify_with_hash functions into the file
6828 lib/silccrypt/silcpkcs.[ch].
6830 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6832 * The client entry's userinfo pointer must be always valid.
6833 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6834 will fail since it requires the userinfo. Now, the userinfo
6835 is allocated as "" if actual userinfo does not exist. Actually,
6836 it must exist and it is totally Ok to drop client connections
6837 that does not announce the userinfo. However, we will make
6838 this workaround for now.
6840 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6841 to return the remote port by socket.
6843 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6845 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6846 SILC_SERVER_PENDING_EXEC and added an new macro
6847 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6848 data or when error occurs while processing the pending command.
6850 Added new argument `destructor' into silc_server_command_pending
6851 and to the SilcServerCommandPending object. This destructor is
6852 now called after calling the pending callback or if error occurs
6853 immediately. If error occurs the actual pending callback won't
6854 be called at all - only the destructor. The destructor may be
6855 NULL if destructor is not needed.
6857 All this applies for client library code as well. Similar
6858 changes were made there as well for the pending commands.
6860 In the client, the application must now allocate the
6861 SilcClientCommandContext with the silc_client_command_alloc
6864 * Added reference counter to the SilcServerCommandContext. Added
6865 function silc_server_command_alloc and silc_server_command_dup
6868 Same type of functions added to the client library for the same
6871 * Removed the cmd_ident from IDListData away since it is now
6872 global for all connections. It is the command identifier used
6873 in command sending and with pending commands. The affected file
6876 * Added reference counter to the SilcSocketConnection objecet to
6877 indicate the usage count of the object. The object won't be
6878 freed untill the reference counter hits zero. Currently only
6879 server uses this, and client ignores it. The client must be
6880 set to use this too later. The affected files are
6881 lib/silccore/silcsockconn.[ch]. Added also the function
6882 silc_socket_dup to increase the reference counter.
6884 This was mainly added because it is possible that the socket
6885 is removed underneath of pending command or other async
6886 operation. Now it won't be free'd and proper DISCONNECTING
6887 flags, etc. can be set to avoid sending data to connection that
6888 is not valid anymore.
6890 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6891 the connection. After that it sets SILC_SET_DISCONNECTED.
6892 It is, however, possible that the socket data is not still freed.
6893 The silc_server_packet_process now checks that data is not
6894 read or written to connection that is DISCONNECTED. The socket
6895 get's freed when the reference counter hits zero.
6897 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6899 * Changed the client operation API: channel_message operation's
6900 `sender' is now the client entry of the sender, not the nickname
6901 and the `channel' is the channel entry, not the channel name.
6903 In the private_message operation the `sender' is now also the
6904 client entry of the sender not the nickname.
6906 Affected file is lib/silcclient/ops.h and all applications
6907 using the client operations.
6909 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6911 * Moved the calling of ops->connect() from connect_to_server_final
6912 into receive_new_id functin since that is the point when the
6913 client is actually allowed to send traffic to network. The
6914 affected file is lib/silcclient/client.c.
6916 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6918 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6919 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6920 (if needs broadcasting) instead of broadcasting the packets one
6921 by one which would make a burst in the network traffic.
6923 * Added `broadcast' argument to the functions in silcd/server.[ch]
6924 silc_server_create_new_channel[_with_id] to indicate whether
6925 to send New Channel packet to primary router.
6927 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6929 * Added new function into the silcd/server.[ch] files:
6930 silc_server_create_new_channel_with_id to create new channel with
6931 already existing Channel ID.
6933 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6934 lib/silccore/silcpacket.h. This packet is used t send list of
6935 Set Mode payloads inside one packet. Server uses this to set
6936 the modes for the channels and clients on those channels, that it
6937 announced to the router when it connected to it. The protocol
6938 specification has been updated accordingly.
6940 * The silc_server_new_channel did not handle the packet coming
6941 from normal server as it normally does not send that. However,
6942 when it announces its channels it does send it. Implemented
6943 the support for that.
6945 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6946 into the file lib/silccore/id.h.
6948 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6950 * Fixed memory leaks in the functions silc_idlist_del_client,
6951 silc_idlist_del_channel and silc_idlist_del_server in the file
6952 silcd/idlist.c. All of those leaked like a sieve.
6954 * Fixed some small memory leaks in the client's function
6955 silc_client_notify_by_server.
6957 * Added functions into silcd/server.c: silc_server_announce_clients,
6958 silc_server_announce_channels and silc_server_announce_server.
6959 These functions are used by normal and router server to announce
6960 to its primary router about clients, channels and servers (when
6961 router) that we own. This is done after we've connected to the
6964 These functions effectively implements the following packet types:
6965 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6966 and SILC_PACKET_NEW_ID_LIST.
6968 * Added new functions into the silcd/packet_receive.[ch]:
6969 silc_server_new_id_list, silc_server_new_channel_list and
6970 silc_server_new_channel_user_list to handle the incoming
6971 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6973 * Added support of changing Channel ID in the function
6974 silc_server_replace_id. If the server that announces a channel
6975 to the router already exists in the router (with same name but
6976 with different Channel ID), router is responsible to send
6977 Replace ID packet to the server and force the server to change
6978 the Channel ID to the one router has.
6980 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6981 client that the Channel ID has been changed by the router. The
6982 normal server sends this to the client. Client must start using
6983 the new Channel ID as the channel's ID.
6985 Implemented handling of this new type into lib/silcclient/client.c
6986 into the function silc_client_notify_by_server.
6988 * Added new function silc_idlist_replace_channel_id into the files
6989 silcd/idlist.[ch] to replace the Channel ID.
6991 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6993 * Call silc_server_command_identify_check always when processing
6994 the IDENTIFY command in silcd/command.c
6996 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6998 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6999 send keepalive packets. The packet can be sent by clients,
7000 servers and routers.
7002 Added function silc_socket_set_heartbeat into the file
7003 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
7004 If not set, the heartbeat is not performed. The actual
7005 heartbeat is implemented in the low level socket connection
7006 library. However, application is responsible of actually
7009 Added silc_server_send_heartbeat to send the actual heartbeat
7010 packet into silcd/packet_send.[ch]. Server now performs
7011 keepalive with all connections.
7013 * Added silc_task_get_first function into lib/silcutil/silctask.c
7014 to return the timeout task with shortest timeout. There was a bug
7015 in task unregistration that caused problems. TODO has been
7016 updated to include that task system must be rewritten.
7018 * The client library will now resolve the client information when
7019 receiving JOIN notify from server for client that we know but
7020 have incomplete information.
7022 * Rewrote parts of silc_server_remove_from_channels and
7023 silc_server_remove_from_one_channel as they did not remove the
7024 channel in some circumstances even though they should've.
7026 * Encryption problem encountered in server:
7028 The LEAVE command used to send the Channel Key packet to the
7029 router immediately after generating it. However, the code
7030 had earlier sent Remove Channel user packet but not immediately,
7031 ie. it was put to queue. The order of packets in the router
7032 was that Channel Key packet was first and Remove Channel User
7033 packet was second, even though they were encrypted in the
7034 reverse order. For this reason, MAC check failed. Now, this
7035 is fixed by not sending the Channel Key packet immediately but
7036 putting it to queue. However, this is more fundamental problem:
7037 packets that are in queue should actually not be encrypted
7038 because packets that are sent immediately gets encrypted
7039 actually with wrong IV (and thus MAC check fails). So, packets
7040 that are in queue should be encrypted when they are sent to
7041 the wire and not when they put to the queue.
7043 However, the problem is that the current system has not been
7044 designed to work that way. Instead, the packet is encrypted
7045 as soon as possible and left to the queue. The queue is then
7046 just purged into wire. There won't be any fixes for this
7047 any time soon. So, the current semantic for packet sending
7050 o If you send packet to remote host and do not force the send
7051 (the packet will be in queue) then all subsequent packets to the
7052 same remote host must also be put to the queue. Only after the
7053 queue has been purged is it safe again to force the packet
7056 o If you send all packets immediately then it safe to send
7057 any of subsequent packets through the queue, however, after
7058 the first packet is put to queue then any subsequent packets
7059 must also be put to the queue.
7061 Follow these rules and everything works fine.
7063 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7065 * Added new function silc_server_remove_clients_by_server to
7066 remove all client entries from ID list when the server connection
7067 is lost. In this case it is also important to invalidate all
7068 client entires as they hold the invalid server entry. This
7069 fixes fatal bug when server has lost connection and will reconnect
7072 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7074 * Made some sanity checks to silc_server_daemonise like to check
7075 whether the requested user and group actually exists.
7077 * Added sanity check to SKE's silc_ske_responder_finish to check
7078 that the public and private key actually is valid.
7080 * Invalidate the client's nickname when receiving Replace ID
7081 packet and the Client ID is being replaced. This means that the
7082 server will query the nickname if someone needs it (client)
7085 * Sort the ID Cache in client library when the ID Cache data
7086 has changed (needs sorting).
7088 * Do not allow for SILC client to create several connections to
7089 several servers. The client does not support windows right now
7090 and generating multiple connections causes weird behaviour.
7092 Irssi-silc client does support windows and can handle several
7093 connections without problems, see: www.irssi.org and SILC plugin.
7095 * Fixed some places where client was added to the IDList. The
7096 rule of thumb is following (in order to get everything right):
7097 If the client is directly connected local client then the
7098 `connection' argument must be set and `router' argument must be
7099 NULL to silc_idlist_add_client function. If the client is not
7100 directly connected client then the `router' argument must
7101 bet set and the `connection' argument must be NULL to the
7102 silc_idlist_add_client function.
7104 * The funtion silc_server_packet_send_local_channel actually did
7105 not check whether the client was locally connected or not. It
7106 does that now. Fixed a bug related to LEAVE command.
7108 * Fixed Remove Channel User payload parsing bug in server's
7109 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
7111 * The server's silc_server_save_channel_key now checks also the
7112 global ID list for the channel as it might not be in the local
7113 list. Fixed a bug related to LEAVE command.
7115 * Is this the end of the [<unknown>] buglet that has been lurking
7116 around for a long time? A little for loop fix in server's
7117 silc_server_command_whois_parse that is used by both IDENTIFY
7118 and WHOIS command. At least, this was a clear bug and a cause
7119 of one type of [<unknown>] buglet.
7121 * WHOIS and IDENTIFY commands call the function
7122 silc_server_command_[whois/identify]_check function even if
7123 we are not router server.
7125 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7127 * Added --with-gmp configuration option. If set the GMP
7128 is always compiled in the SILC source tree. If not set then
7129 it is checked whether the system has the GMP3 installed. If
7130 it has then the GMP won't be compiled (the system's headers
7131 and library is used), if it doesn't have it then the GMP is
7132 compiled in the SILC source tree.
7134 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7136 * Changed RSA private exponent generation to what PKCS #1
7137 suggests. We try to find the smallest possible d by doing
7138 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
7139 not security fix but optimization.
7141 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7143 * Added new config entry [Identity] to fork the server and run
7144 it as specific user and group. A patch from Bostik.
7146 * Imported Dotconf configuration library into lib/dotconf.
7147 This will be used to create the SILC configuration files later.
7148 It will appear in the distsribution after this commit.
7150 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7152 * A big code auditing weekend happening. Auditing code for
7153 obvious mistakes, bugs and errors. Also, removing any code
7156 Removed files for being obsolete:
7158 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
7159 inline in the file lib/silcutil/silcbuffer.h)
7161 o lib/silcutil/silcbufutil.c (the header has inline versions)
7163 Changed code to fix possible error conditions:
7165 o The buffer formatting routines now check that the destination
7166 buffer really has enough space to add the data. This applies for
7167 both buffer formatting and unformatting
7168 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
7169 unformatting was changed to accomodate following rules:
7170 XXX_*STRING_ALLOC will allocate space for the data into the pointer
7171 sent to the function while XXX_*STRING will not allocate or copy
7172 the data into the buffer. Instead it sets the pointer from the
7173 buffer into the pointer sent as argument (XXX_*STRING used to
7174 require that the pointer must be allocated already). This change
7175 makes this whole thing a bit more consistent and more optimized
7176 (note that the data returned in the unformatting with XXX_*STRING
7177 must not be freed now). The routines return now -1 on error.
7179 o Tried to find all code that use buffer_format and buffer_unformat
7180 and added return value checking to prevent formatting and
7181 especially unformatting errors and possible subsequent fatal
7184 o Changed ske->x and ske->KEY to mallocated pointers in
7185 lib/silcske/silcske.h. Fixed possible data and memory leak.
7187 o Added return value checking to all *_parse* functions. Fixed
7188 many memory leaks as well.
7190 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
7191 so that buffer overflows would not happen. All code now also
7192 checks the return value as it can fail.
7194 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7196 * Added reconnection support to server if the normal server looses
7197 its connection to the router (for example if router is rebooted).
7198 The server performs normal reconnection strategy implemented
7199 to the server. Affected file silcd/server.c.
7201 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7203 * Added new packet type SILC_PACKET_SET_MODE that is used to
7204 distribute the information about changed modes (for clients,
7205 channels and clients channel modes) to all routers in the
7206 network. Updated the protocol specification accordingly.
7208 Added functions into silcd/packet_send.c and
7209 silcd/packet_receive.c: silc_server_send_set_mode,
7210 silc_server_set_mode.
7212 Added new files silcmode.[ch] into lib/silccore that implements
7213 the encoding and decoding of Set Mode Payload. Added new type
7214 SilcSetModePayload. Moved the definitions of different modes
7215 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
7217 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7219 * Oops, a little mistake in server's connection authentication
7220 protocol. The protocol is not ended with FAILURE but with
7221 SUCCESS if the authentication is Ok. :) Affected file is
7224 * Implemented NICK_CHANGE notify handling in server in the file
7225 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
7226 the local clients on the channel. After the changing nickname
7227 in router environment snhould work and the [<unknown>] nickname
7228 should appear no more.
7230 The silc_server_replace_id function that receives the Replace ID
7231 payload now sends the NICK_CHANGE notify type also in the file
7232 silcd/packet_receive.c
7234 * Changed WHOIS and IDENTIFY command to support the maximum amount
7235 of arguments defined in protocol specs (3328 arguments). This
7236 fixed a bug that caused problems when there were more than three
7239 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7241 * Added extra parameter, command identifier, to the
7242 silc_client_send_command so that explicit command identifier
7245 Changed that ID list routines uses specific command identifier
7246 when sending WHOIS/IDENTIFY requests to the server so that they
7247 can be identified when the reply comes back.
7249 Affected files lib/silcclient/command.[ch],
7250 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
7252 * Added `sender' argument to silc_server_packet_send_to_channel
7253 to indicaet the sender who originally sent the packet to us
7254 that we are now re-sending. Ignored if NULL. Affected file
7255 silcd/packet_send.[ch].
7257 * Added some server statistics support in silcd/server_internal.h
7258 SilcServerStatistics structure and around the server code. Also
7259 send some nice statistics information when client is connecting
7262 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7264 * Fixed channel ID decoding in server's JOIN command reply in
7265 silcd/command_reply.c
7267 * Fixed braodcasting of replace ID payload to not to send it if
7268 we are standalone server in silcd/packet_receive.c.
7270 * Fixed all channel message sending routines to not to send
7271 packets to clients that has router set, since they are routed
7272 separately in the same function earlier. Affects file
7273 silcd/packet_send.c and all channel packet sending functions.
7275 * In USERS reply, res_argv[i] are not allocated, the table
7276 is allocated. Thus changed that free the table, not its
7279 * In server's whois_check and identify_check if the client is
7280 locally connected do not send any WHOIS commands - they are not
7283 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7285 * Fixed some minor bugs in client when sending WHOIS command. The
7286 arguments was in wrong order.
7288 * Removed statis function add_to_channel from server in
7289 silcd/command.c that was previously used with the joining but
7292 * Tested USERS command in router environment successfully with two
7293 routers, two servers and two clients.
7295 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7297 * Reorganized the USERS command and command reply in client library
7298 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
7299 When the command is given by user we register a pending command
7300 callback that will reprocess the command after the reply has been
7301 received from the server. When reprocessing the packet we then
7302 display the information. Thus, the USERS information is displayed
7303 now in the command callback instead of in the command reply
7304 callback. The processing of the command is same as previously
7305 when server has sent the command reply in the JOINing process.
7307 * Added to USERS command in silcd/command_reply.c to join the client,
7308 we didn't use to know about, to the channel after we've created
7309 a client entry for it. Also, for clienet we did know already still
7310 check whether it is on the channel or not and add it if not.
7312 * Removed silc_server_command_join_notify as the function and its
7315 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7317 * Changed the client's pending command handling to the same as the
7318 server's pending command handling. It is also now possible to
7319 execute command reply functions from other command reply
7320 function as the function callbacks for commands and command
7321 replies are one and same. The pending commands are not static
7322 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
7323 in client connection context. Thus, pending commands are server
7324 connection specific as it is convenient.
7326 Changed the function silc_client_command_pending and
7327 silc_client_command_pending_del and added new function
7328 silc_client_command_pending_check. Removed the
7329 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
7332 * Added cmd_ident, current command identifier, to the client
7333 connection context in lib/silcclient/client.h to keep track on
7334 command identifiers used in command sending. Client's command reply
7335 function handling now supports the mandatory command identifiers.
7337 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
7338 funtions in client to fully support pending command callbacks.
7340 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
7341 as one of the arguments to the application in the command reply
7344 * NOTE: The FORWARDED flag is depracated. It used to be depracated
7345 before first releasing SILC but came back. Now it is removed again
7346 and should come back nomore. The FORWARDED flag was used only
7347 by the JOINing procedure by forwarding the command packet to router.
7348 Now, the JOINing procedure has been changed to more generic (due
7349 to various router environment issues) and FORWARDED is not needed
7350 anymore for anything. The protocol specification is yet to be
7353 Now, removed silc_server_packet_forward from server and the flag
7354 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
7356 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7358 * Renamed NAMES command to USERS command. The NAMES was named that
7359 due to historical reasons. Now it is renamed. Also, rewrote
7360 parts of the USERS command. The nickname list is not sent anymore
7361 by the server. Only Client ID and mode lists are sent in the USERS
7362 command. Changed this also to the protocol specification.
7364 The client now resolves the names and stuff after it receives
7365 the USERS list from the server when joining to the channel.
7367 * WHOIS and IDENTIFY commands has been changed to support multiple
7368 Client ID's per command. One can now search for multiple users
7369 in the network by sending only one WHOIS or IDENTIFY command.
7370 Changed the code and the protocol specifications.
7372 * Removed silc_server_command_identify_parse and changed that IDENTIFY
7373 uses silc_server_command_whois_parse to parse the request. */
7375 * If normal server, do not parse the WHOIS and IDENTIFY requests
7376 before sending it to the router. Saves some time.
7378 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7380 * Fixed JOIN command on client library. Wrong number of arguments
7381 used to crash the client.
7383 * Added silc_server_channel_has_global function to check whether
7384 channel has global users or not.
7386 * Added silc_server_channel_has_local function to check whether channel
7387 has locally connected clients on the channel.
7389 * The silc_server_remove_from_one_channel now checks whether the
7390 channel has global users or not after given client was removed from
7391 the channel. It also checks whether the channel has local clients
7392 on the channel anymore. If it does not have then the channel entry
7393 is removed as it is not needed anymore.
7395 * The silc_server_notify now checks on JOIN notify whether the joining
7396 client is one of locally connected or global. If it is global then
7397 the channel has now global users on the channel and that is marked
7398 to the channel entry. Also, it now saves the global client to
7399 global list who is joining and JOINs it to the channel. This is
7400 for normal server, that is.
7402 Changed silc_server_send_notify_on_channel,
7403 silc_server_packet_relay_to_channel and
7404 silc_server_packet_send_to_channel check if we are normal server
7405 and client has router set (ie. global client) do not send the
7406 message to that client, as it is already routed to our router.
7408 * Implemented LEAVE notify type handling in silc_server_notify
7411 * Tested LEAVE command in router environment successfully. Tested
7412 with two routers, two servers and two clients.
7416 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
7418 * Implemented SIGNOFF notify type handling in silc_server_notify
7421 * silc_server_remove_id now removes the client entry from all channels
7422 it has joined and thusly sends SIGNOFF notify type.
7424 * Rewrote the NAMES list generation in server by removing two excess
7425 loops. The lists are created now inside one loop.
7427 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7429 * silc_server_remove_channel_user checks now also global list
7430 for channel and client.
7432 * silc_server_new_channel_user checks now both local and global
7433 list for channel and client. Fixed a bug in client id decoding.
7434 Used to decode wrong buffer.
7436 * silc_server_channel_message checks now both local and global
7437 list for channel entry.
7439 * Tested channel joining (hence JOIN) in router environment
7440 successfully. Tested with two routers, two servers and two
7443 * Tested channel message sending in router environment successfully.
7445 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7447 * Added silc_server_save_channel_key into server.[ch] to save the
7448 received channel key in Channel Key payload processing. It is
7449 also used in JOIN command reply handling.
7451 Equivalent function silc_client_save_channel_key added into
7452 client.[ch] into client library.
7454 * Changed JOIN command reply to send information whether the channel
7455 was created or not (is existing already) and the channel key
7456 payload. Changed protocol specs accordingly.
7458 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
7459 the request was sent by ID and not by nickname. Crashed on
7462 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7464 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
7465 now correctly save the received data.
7467 * silc_server_free_sock_user_data now notifies routers in the
7468 network about entities leaving the network.
7470 At the same time implemented functions silc_server_remove_id
7471 and silc_server_send_remove_id to receive and send REMOVE_ID
7472 packets. The packet is used to notify routers in the network
7473 about leaving entities. The ID removed will become invalid in
7476 * Added function silc_idlist_del_server into server. Removes and
7477 free's server entry from ID list.
7479 * silc_server_private_message function now checks, if we are router,
7480 that the destination ID really is valid ID, naturally.
7482 * In router when NEW_ID packet is received (for new client) the
7483 hash of the Client ID is saved in the ID Cache but the
7484 client->nickname is set to NULL, instead of putting the hash
7487 IDENTIFY command now also checks that client->nickname must be
7488 valid. If it is not if will request the data from the server who
7489 owns the client. Added new function
7490 silc_server_command_identify_check.
7492 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
7493 to set the command to already allocated Command Payload.
7495 * Tested private message sending in router environment with two
7496 routers, two servers and two clients. Fixed minor bugs and now
7499 * Fixed segfault from client's NAMES command. Used to crash if
7502 * Forwarded packets must not be routed even if it is not destined
7503 to the receiver. Changed server code comply with this.
7505 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7507 * Added `require_reverse_mapping' boolean value to ServerParams
7508 structure. If TRUE (not default) the server will require that
7509 the connecting host has fully qualified domain name.
7511 If the reverse mapping is not required and hostname could not be
7512 found the IP address is used as hostname.
7514 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7516 * Implemented version string checking to both client and server.
7517 The check is incomplete currently due to the abnormal version
7518 strings used in development version of SILC.
7520 * Changed all command functions in server to use the new
7523 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7525 * Changed char *data to unsigned char *data in ID Cache system to
7526 support binary data as ID Cache data. Changed code to support
7527 binary data in lib/silccore/idcache.c.
7529 * Renamed silc_server_packet_relay_command_reply to
7530 silc_server_command_reply as it is normal packet receiving
7531 function. Rewrote the function to accept command replys for
7532 servers and not only for clients.
7534 * Mark remote router always as registered server if we are connecting
7535 to it. Otherwise, commands sent by the router to us are ignored.
7537 * All ID List find routines now returns the ID Cache Entry pointer
7538 as well if requested.
7540 * WHOIS command works now in router environment, tested with two
7541 routers, two servers and two clients.
7543 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
7544 in router environment (as it is almost equivalent to WHOIS) but
7545 hasn't been tested thoroughly. Added new functions:
7547 silc_server_command_identify_parse
7548 silc_server_command_identify_send_reply
7549 silc_server_command_identify_from_client
7550 silc_server_command_identify_from_server
7552 * Disabled route cache adding because adding two different ID's with
7553 same IP replaces the old cache entry thus giving wrong route.
7554 The entry->router->connection is always the fastest route anyway
7555 so route cache may not be needed. Of course, new routes maybe
7556 established after receiving the ID when the entry->router->connection
7557 might not be anymore the most optimal.
7559 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7561 * Add route cache for received ID for fast routing.
7563 * Added silc_server_packet_route to route received packet on router
7564 that is not destined to us.
7566 * Renamed silc_server_get_route to silc_server_route_get.
7568 * Added id_string and id_string_len fields into SilcServer to
7569 include encoded ServerID for fast comparing without excess
7570 encoding of the ID's.
7572 * Cleaned up WHOIS command on server side. Added following static
7575 silc_server_command_whois_parse
7576 silc_server_command_whois_check
7577 silc_server_command_whois_send_reply
7578 silc_server_command_whois_from_client
7579 silc_server_command_whois_from_server
7581 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
7582 arguments in command replies. All command functions should be
7583 updated to use this macro.
7585 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7587 * Minor typo fixes on command reply handling on server.
7589 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7591 * Added silc_server_command_add_to_channel internal routine to add
7592 the client to the channel after router has created the channel and
7593 sent command reply to the server.
7595 * Added generic silc_server_send_command to send any command from
7598 * Use static buffer with ID rendering instead of duplicating data.
7600 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7602 * Fixed a channel user mode bug when joining to a channel server gave
7603 everybody channel founder rights, oops.
7605 * We mark ourselves as the router of the incoming server connection
7606 if we are router ourselves. This way we can check in some packet
7607 sending functions whether it is locally connected server. For
7608 incoming router connections we put NULL.
7610 * For router sending packets locally means now always sending the
7611 packet cell wide; to local clients and local servers. For normal
7612 server sending packet locally means sending it to only local
7615 * Fixed the JOIN command to really work in router environment. If the
7616 channel is created it is always created by the router. Router is
7617 also responsible of making the initial joining to the channel,
7618 sending JOIN notify to the sending server and distributing
7619 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
7620 does not exist server doesn't do anything else but forward the
7621 command to the router which performs everything.
7623 * Added silc_server_send_channel_key function to send the Channel Key
7626 * Added silc_server_create_channel_key to create new channel key. The
7627 channel key is now re-generated everytime someone joins or leaves
7628 a channel, as protocol dictates. Note: channel->key_len is the
7631 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7633 * Splitted server.[ch] finally. Created now packet_send.[ch] and
7634 packet_receive.[ch] to separate packet sending and receiving
7635 routines. The server.[ch] now includes everything else including
7636 actual packet processing (writing and reading data) and other
7639 Renamed silc_server_private_message_send_internal to
7640 silc_server_send_private_message. The routine is still though
7641 used only to relay private messages as server does not send
7642 private messages itself.
7644 Renamed silc_server_new_channel to silc_server_create_new_channel
7645 and added new function sicl_server_new_channel that handles the
7646 incoming New Channel packet. Added also new sending function
7647 silc_server_send_new_channel to send New Channel Payload.
7649 * Added new function silc_server_notify to process incoming notify
7650 packet to the server/router. Server may then relay the notify
7651 to clients if needed.
7653 * Added new function silc_server_new_channel_user to process incoming
7654 New Channel User packet. Router will redistribute the packet and
7655 send JOIN notify to its local clients and locally connected servers
7656 if needed. Normal server will send JOIN notify to its local client
7657 on same channel when received this packet. Added also corresponding
7658 sending function silc_server_send_new_channel_user to sent the
7661 * Added boolean route argument to send_notif_to_channel and
7662 packet_send_to_channel functions to attempt to route the packet
7663 if it is TRUE and send only locally if it is FALSE.
7665 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7667 * silc_server_replace_id now broadcasts the received replace ID
7668 packet if it is not broadcast packet already. The router must
7669 broadcast to inform other routers about changed ID.
7671 * Added backpointer to server's router into SilcServer context in
7672 silcd/server_internal.h.
7674 * Fixed silc_server_packet_broadcast to send correct broadcast
7677 * The channel key is now distributed to the local client as soon
7678 as it is received from the router (in router environment) so that
7679 no other packet may be sent for the channel until client has
7682 * silc_server_remove_channel_user now broadcasts the received
7683 Remove Channel User packet if it is not broadcast packet already.
7684 The router must broadcast to inform other routers about removed
7687 * Added users field into SilcPacketContext that is a reference count
7688 of the context. One can increase the reference count by calling
7689 silc_packet_context_dup which is now changed to just increase the
7690 reference count instead of duplicating the data. The reference
7691 count is decresed by calling silc_packet_context_free that will
7692 free the data after the reference count hits zero.
7694 For now on the packet context and everything allocated into it
7695 (including the raw packet from network) must be freed by calling
7696 the new silc_packet_context_free function. Added also new function
7697 silc_packet_context_alloc that must be used now to allocate the
7698 context. This also means that if a routine is asynchronous from
7699 silc_[client/server]_packet_parse_type the packet context must
7700 be duplicated by calling silc_packet_context_dup. Otherwise it
7701 gets free'd after silc_[client/server]_packet_parse_type returns.
7702 Also, one must remember that if packet is duplicated then its
7703 reference count must be decresed by calling the free function as
7704 many times as it was duplicated.
7706 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7707 from both client and server.
7709 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7711 * Made joining to a channel working in router environment.
7713 * Cleaned up JOIN command on server side and create function
7714 silc_server_command_join_channel internal routine to make the
7717 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7719 * Changed silc_command_pending list to SilcDList. Also, added
7720 `ident' field to SilcServerCommandPending structure to identify
7721 the reply and to call correct callback.
7723 Added silc_server_command_pending_check function to replace the
7724 corresnponding macro. The silc_command_pending list is not
7727 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7728 to set identifier to previously allocated Command Payload. It
7729 is used to set identifier for command when resending Command
7732 * Added silc_command_payload_encode_payload to encode Command
7733 Payload buffer from SilcCommandPayload structure.
7735 * Added silc_argument_payload_encode_payload to encode Argument
7736 payload buffer from SilcArgumentPayload structure.
7738 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7740 * Changed WHOIS command to support router connection on server side.
7741 The whois request is always sent to router unless the server is
7742 standalone server. After server has received the reply from the
7743 router will it send the reply to the client.
7745 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7746 broadcast received broadcast packet. The function is used only
7747 by router. The broadcast packet is always sent to the router's
7750 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7751 render given ID to printable string, for log files for example.
7753 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7755 * Made basic router to router connections working. At least they
7756 can now connect to each other but nothing really works the way
7757 they are supposed - yet.
7759 * Added new initiator token to RouterConnection configuration
7760 file in silcd/serverconfig.[ch]. It is used to tell whether we
7761 are the initiator to the remote router or whether we'll expect
7762 the other end to connect.
7764 * Moved registering of listener task to silc_server_init, hence
7765 the server starts listenning as soon as it is run, even if it
7766 does not have connections to other routers. Let's see how well
7769 * Changed default connection retry timeouts for more suitable in
7772 * Removed cipher and such arguments from silc_idlist_add_client
7773 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7774 Added new function silc_idlist_add_data to add the keys and stuff
7777 * Added SilcIDListData structure and added it to SilcClientEntry
7778 and SilcServerEntry as their first field in the structure. This
7779 way we can explicitly cast the ID entries to the SilcIDListData
7780 structure and get common data for the entries. In past, we had
7781 to first check what type of connection it is and then cast it to
7782 correct ID entry type. Now, we can directly cast the opaque
7783 pointer to the SilcIDListData (no matter what ID entry it actually
7784 is) and get the data needed.
7786 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7788 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7789 in some circumstances even if threre were timeout tasks, though not
7790 IO tasks, but tasks anyway. Now fixed.
7792 * Defined SilcServerConnection structure to hold connection specific
7793 stuff about directly connected servers and routers. The definition
7794 is currently in silcd/server_internal.h. I thought about having
7795 a bit more important role fro this struct but for now it is used
7796 only when connecting to other server (or router actually).
7798 * Added connecting retry support in server when connecting to
7799 router(s). The retry feature implement exponential backoff
7800 algorithm. Also, added SilcServerParams structure to hold default
7801 parameters for server. For now, it include these retry settings
7802 and are hard coded. After server is moded to be as Silc Server
7803 Library this structure will be more important.
7805 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7807 * Changed client librarys channel->clients table to SilcList and
7808 changed code accordingly.
7810 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7812 * Changed client's channel table to SilcList and changed code
7813 accordingly. Also changed SilcChannelClientEntry to include back-
7814 pointer to the channel so that client entry can use that structure
7815 as list as well and we have fast cross-reference to the channel.
7816 This change dramatically decreased the complexity of channel
7817 handling with client entry and vice versa (removed one extra
7818 loop when searching for channel entry from many functions).
7820 * Changed server->sim from table to SilcDList and changed code
7823 * NAMES command can now be used from user interface. It will show
7824 the user list on the channel, neatly.
7826 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7827 Code now saves realname of the user if it becomes available.
7829 * Renamed configure.in to configure.in.pre and made ./prepare
7830 script to automatically add correct version string to
7831 configure.in which it creates from configure.in.pre.
7833 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7835 * NAMES command reply now shows users mode with the nickname when
7838 * Moved silc_client_ch[u]mode[_char] functions from
7839 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7840 place sucks, they are utility functions and should be in some
7843 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7845 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7848 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7852 * Added TRQ (efficient deque and list library) into lib/trq. This is
7853 a very good list library that is currently used in the SILC. Defined
7854 SilcList API over the library because I didn't like the API very
7855 much. See lib/trq/silclist.h for the API and examples of how to
7856 use the API. Fixed various places in the code to use the new
7857 SilcList API. The SilcList is meant for lists that has a structure
7858 already defined as a list. It is not suitable to add just some
7859 context to the list (in TRQ, the context is the list actually).
7861 So, I defined SilcDList that can be used for the purpose where
7862 predefined list structure does not exit. This can be used as
7863 such list. Now some context just can be added to the SilcDList.
7864 Currently this list is not used in the SILC just yet, though there
7865 are a lot places where this can replace dynamically allocated
7866 tables and I will fix these places, later, to use SilcDList.
7867 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7868 and use TRQ internally).
7870 Also fixed some annoying warning messages that the original TRQ
7871 code generated. Also minor changes to TRQ's Makefile.in.
7873 * Added support for querying by Client ID to both WHOIS and
7874 IDENTIFY commands into server, as required by the protocol.
7876 * Removed method function pointers from SilcBuffer structure. They
7877 weren't used to anything and just increased the context size for
7878 no good reason. This change also made silc_buffer_alloc and
7879 silc_buffer_free functions inline functions.
7881 * Disabled command flooding detection support until it's fixed so
7882 that it accepts commands in but does not execute them more than once
7885 * Added silc_net_localhost(), to return local hostname, into
7886 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7887 that must be initialized before calling silc_client_init.
7889 * Added new function: silc_server_send_notify_on_channels to send
7890 notify messages to all channels client has joined. It is assured
7891 that the message is sent only once per client.
7893 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7894 lib/silcutil/silcutil.[ch] as silc_format function. The new
7895 function is generic and is used by server as well, not only by
7896 the logging routines.
7898 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7899 the provided version string was not acceptable. Added new function:
7900 silc_ske_check_version into lib/silcske/silcske.h. The function
7901 must be implemented by the application (client or server) and it
7902 does not reside in the SKE library. The function checks the version
7903 string remote end sent.
7905 * Added back pointers (to opaque context and to SilcSocketConnection)
7906 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7908 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7909 duplicate packet context structure.
7911 * Changed `notify' client operation to send same arguments as client
7912 receives from server except for ID's. ID's are mapped to correct
7913 ID entry and that is returned. Also, if channel entry is not sent
7914 by server but the notify is for channel the channel entry is sent
7915 to application (otherwise application doesn't know that it is for
7916 channel (library gets it from packet's Destination ID)).
7918 * Added silc_client_remove_from_channels into client library to
7919 remove a client from all channels it has joined to. Used when
7920 received SIGNOFF notify from server. Added also new function
7921 silc_client_replace_from_channels to replace old ID entry with
7922 new ID entry on all channels. Used when received NICK_CHANGE
7925 * Fixed ID Cache list handling in silc_idlist_get_client in
7926 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7927 to get (or query) client by ID.
7929 * Updated TODO list.
7931 * Added connection authentication status message defined by the
7932 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7933 support for these into the code in client and server side.
7935 * Added generic function silc_client_send_command to send any command
7936 with variable argument list. Application should use this function
7937 to send commands if the command functions provided by the library
7938 does not suite for the application's user interface needs.
7940 * Added new `failure' client operation. Application is notified about
7941 received failure packet if client is executing a protocol. In this
7942 case the protocol's execution has failed.
7944 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7945 is required by the protocol.
7947 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7948 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7951 * Added status flag to SilcSKE object to indicate realtime status
7952 of the SKE protocol.
7954 * Application receives now exactly same command reply arguments as
7955 the library receives from server. However, if ID is received the
7956 corresponding ID entry is returned to the application (eg. Client
7957 ID is mapped to correct SilcClientEntry entry and that is returned).
7958 Changed command_reply client operation due to this change.
7960 * Changed all ID's in commands and in command replys as ID Payloads.
7961 Change affected both client and server side codes.
7963 All ID's sent in SILC network (with execption of ID's in SILC
7964 Packet header) are sent in ID Payload to support variable length
7967 * Server now notifies nick changes and notifies all clients on
7968 the channels about the new nickname (about the new Client ID,
7971 * Implemented CMODE command to change channel modes. Supports all
7972 channel modes defined by the protocol specs except ban and invite
7973 lists. (Also, private channel key mode is supported but support for
7974 setting private channel key in client is missing, thus, this mode
7975 has no effect on client side (except that server requires that the
7976 client uses private channel key and normal channel traffic does not
7979 Also, invite mode works per se, but INVITE command does not work
7980 yet correctly, so you can set channel as invite only channel but
7981 inviting clients to the channel does not work (it is yet to be
7982 thought what's the best way to do it).
7984 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7985 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7986 Implemented CUMODE command to change user's mode on the channel.
7987 Supports all modes defined by the protocol specs.
7989 * Added NAMES command reply to return users modes on the channel.
7991 * Removed unnecessary and slow ciphers from lib/silccrypt.
7993 * Set SO_KEEPALIVE option to connection sockets by default.
7995 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7997 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7998 redefined the Notify Payload into protocol specs.
8000 * Added silc_id_payload_parse_id to get ID directly from raw
8003 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8005 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
8006 accept searching by Client ID as well.
8008 * Added support for LEAVE and SIGNOFF notify types in client library.
8010 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
8011 to parse ID Payload from raw data.
8013 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8015 * Added flags parameter into silc_ske_assemble_security_properties
8016 function in lib/silcske/silcske.[ch].
8018 * Changed notify client operation to fit better for notify messages
8019 sent by server. The notify payload received from server is now
8020 passed to the application (after parsing it to SilcNotifyPayload).
8021 It is application's responsibility to retrieve the arguments
8022 from the payload and show the message the way it wants. The message
8023 sent by server is implementation specific.
8025 * Changed public keys to comply with the protocol specification.
8026 Old public keys are not supported anymore and are not compatible.
8028 * Removed nickname from Channel Payload as the latest draft removed
8029 it. The client must resolve the nickname from the NAMES command
8030 reply received when it joined the channel.
8032 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
8034 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8036 * Fixed some errors in protocol specification drafts.
8038 * Created lib/silccore/silcnotify.c to implement Notify Payload
8039 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
8040 generic payloads described by protocol specifications. The file
8041 includes implementations for ID Payload and Argument Payload.
8043 * Changed Command Payload implementation to use the new Argument
8044 Payload. Changed command_xxxx_payload to command_payload_xxxx
8045 to comply with SILC coding conventions.
8047 * Added suppport for Argument Payload handling in Notify Payload
8048 implementation as protocol requires it. Added the new support
8049 into server and client lib as well.
8051 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8053 * Added support for multiple nicknames on same channel. [n] is
8054 added locally to the nickname if there are more than one same
8055 nicknames on the channel.
8057 * Server now sends all nicknames that matched WHOIS request.
8058 Client also shows the list received from server.
8060 * Added TOPIC command to client side. User can now set and show
8061 current topic on channel.
8063 * Added MOTD command to client and server. Also, server sends the
8064 motd when client connects to the server.
8066 * Changed version strings to comply ISO 8601.
8068 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8070 * Fixed protocol error handling in client library. It should now
8071 cope even if the SKE fails for some reason.
8073 * Made new protocol specification drafts for submitting to IETF.
8075 * Implemented TOPIC command to server in silcd/command.c.
8077 * Added two new notify types into lib/silccore/silcnotify.h:
8078 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
8079 notify nickname change and topic setting/change on a channel.
8081 * API change of command_reply operation in client library. The
8082 application gets now the status type received from server as well.
8084 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8086 * Removed the function just added to lib/silcutil/silcschedule.[ch].
8088 * Cras fixed and optimized the packet handling even further and
8089 it should work now. Minor change to the prototype of function
8090 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
8092 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8094 * Added new function into lib/silcutil/silcschedule.[ch]:
8095 silc_schedule_with_fd to select() a specified fd. The function
8096 returns after timeout expires or data arrives or goes. The
8097 function is used by packet routines to wait that all data is
8098 received from network.
8100 * Fixed data reading from network in lib/silccore/silcpacket.c.
8101 The code now assures that all data is read from the fd and then
8102 continues packet processing. This was a bug fix since the code
8103 used to drop some data in some circumstances.
8105 * Added new function into lib/silcclient/client.[ch]:
8106 silc_client_start_key_exchange to start key exchange after
8107 connection has been established to server. The code internally
8108 now uses this funtion but its main purpose was to provide it
8109 for applications that perform their own connecting. After
8110 application has created a connection it merely calls this
8111 function to start the key exchange between client and server.
8112 The library takes care of everything else after that.
8114 Updated also lib/silcclient/README to explain the usage of
8117 * Do not send to application information that connection has
8118 been established. Application gets notified it by connect
8121 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8123 * Applied cras's patch to add silc_schedule_one function. The
8124 function runs scheduler once and returns.
8126 * Fixed the scheduler after cras messed it up. The timeout
8127 handling works now as it's supposed to work.
8129 * Added into lib/silccore/ silcnotify.h to include notify
8130 message types support. Changed silc_server_send_notify*
8131 functions, in server.[ch], to support those new notify types.
8132 Added the support for the notify types into client library,
8133 as well. Added new notify client operation into ops.h in
8136 * Changed silc_server_packet_send_to_channel to send normal
8137 packets instead of just channel message packets. The function
8138 is now used to send the notify packets to channels. It is not
8139 used to send channel message packets anymore, as server never
8142 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
8143 va_arg()s as it seems to require it nowadays. I guess, if SILC
8144 is compiled with older va_arg() the new code should work anyway.
8146 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8148 * Splitted core library. Core library (lib/silccore) includes
8149 now only SILC protocol specific core (and common) components.
8150 Created new utility library (lib/silcutil) that includes more
8151 generic purpose stuff. The stuff for util library was taken
8152 from the old core library. This was minor and easy split.
8154 * Created SILC Client Library (lib/silcclient) that includes
8155 implementation of the SILC client without user interface. This
8156 was major move from silc/ directory. The code has been changed
8157 so that it is transparent towards the user interface. The
8158 silc/ directory includes now the same user interface as before
8159 and it uses the new client library. Read lib/silcclient/README.
8160 Basicly, the client library performs everything else related
8161 to SILC except user interface handling. Also, configuration
8162 files are considered to be part of user interface and library
8163 does not handle them.
8165 This change also changed a lot of structures, function naming etc.
8166 Most important change was that SilcClientWindow object was
8167 renamed to SilcClientConnection in the client library. Created
8168 also new file lib/silcclient/ops.h. Also added new files
8169 silc/local_command.[ch] and silc/client_ops.[ch].
8171 All these changes were made to make it easier for user interface
8172 designers to create what ever user interface for the SILC client
8175 It is also expected that the server will be moved to lib
8176 directory as well and SILC Server Library will be created;
8177 sometimes in the future.
8179 * Removed Local commands from lib/silccore/silccommand.h as
8180 they are application specific and new client library does not
8181 handle any of those anymore.
8183 * Several functions moved to lib/silcutil/silcutilc.[ch] from
8184 old client implementation in silc/.
8186 * Added support for callback functions in SILC_LOG_* macros.
8187 Application can now set its own callbacks that will be called
8188 instead of using the default functions that will always print
8189 the debug messages to stderr (or stdout). Also, debugging can
8190 now be disabled by setting silc_debug to FALSE and re-enabled by
8191 setting it to TRUE. Note, that logging will still work even
8192 if debugging is disabled.
8194 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
8195 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
8196 silc_log_reset_debug_callbacks.
8198 * To enable debugging in silc client one must give now -d
8199 option on command line.
8201 * Changed silc_schedule_init to automatically allocate task queues
8202 if they are not allocated before calling it.
8204 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8206 * Added GMP 3.1 into math library.
8208 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8210 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
8211 a channel in SILC network. The packet is used by servers and
8212 routers to notify other routers that user has left a channel.
8213 This little feature was missing until now. Added the feature
8214 to protocol specification as well.
8216 Added functions: silc_server_send_remove_channel_user and
8217 silc_server_remove_channel_user into server.[ch].
8219 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
8220 lib/silccore/silcpacket.h. However, they are not implemented
8223 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8225 * Fixed joining to a channel and sending channel messages
8226 between server and router. The channel message sending should
8227 now work inside a cell.
8229 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8231 * Fixed the private message sending between server and router.
8232 The private message sending should now work inside a cell.
8234 * Added silc_server_replace_id into server.[ch] to replace
8235 existing ID in the SILC network.
8237 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
8238 and silc_idlist_replace_server_id into idlist.[ch] in server.
8240 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8242 * Fixed the server to server connections. Server can again now
8243 connect to router. Router to router connections probably does
8246 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8248 * Added dynamic protocol registering support. Now protocols can
8249 registered and unregistered on the fly. Patch by cras.
8251 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8253 * Added lib/contrib directory to hold routines that some platforms
8254 don't have but are needed by SILC.
8256 * Added getopt.c, getopt1.c and getopt.h from GNU C library
8257 into lin/contrib to provide getopt() and getopt_long() for
8258 those who don't have it.
8260 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8262 * Added AWAY command to client. When away message is set and
8263 client receives a private message packet the client automatically
8264 replies to the sender with the away message.
8266 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
8267 bug seemed to be the cause of recent problems when compiling
8270 * Added version detection support to SKE protocol specification
8271 and added the new changes to the SKE implementation as well.
8272 There were other minor changes in the SKE protocol as well.
8274 Many changes in lib/silcske/silcske.[ch] and in
8275 lib/silcske/payload.[ch].
8277 * Added ^U functionality, clear input line. Patch from cras.
8279 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8281 * Mainly small bugfixes on core library. Fixed some debugging
8282 logging and buffer overflow in silclog.c.
8284 * Updated config.sub and config.guess on the distribution tree.
8286 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8288 * Added command lagging support in server. Client may execute
8289 commands now only once in two seconds.
8291 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8293 * Optimized packet reception. MAC computation and checking is now
8294 also more optimized. A lot previously duplicated code is now
8295 used as generic by both client and server.
8297 * Fixed key pair generation in clientutil.c
8299 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8301 * Added into lib/silccore/silcbufutil.[ch] new function;
8302 silc_buffer_realloc.
8304 * Moved generic packet sending/encryption functions to
8305 lib/silccore/silcpacket.[ch] from client and server. Some
8306 rewriting of the functions.
8308 * Moved all generic packet reception/decryption functions to
8309 lib/silccore/silcpacket.[ch] from client and server. The
8310 packet processing is now much cleaner in both client and server.
8311 These were major changes in both client and server.
8313 * Created many common functions in server to do packet sending.
8314 Previously code were duplicated a lot, this has been removed
8317 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8319 * Rewrote major parts of the ID cache system. Don't know
8320 whether it is better now or not but at least the API is more
8323 * Major rewrite on ID cache stuff on client because of the ID
8324 cache API changes. Added idlist.c to client.
8326 * Also major rewrite on ID cache stuff on server as well.
8327 Major rewrite of idlist.[ch]. SilcXXXList's are now named
8328 SilcXXXEntry's. We won't keep anymore idlist specific pointers
8329 in hand, instead they are all put into the ID cache system now.
8330 All server_idlist_* routines uses ID cache now instead of
8331 traversing its own lists (those lists does not exist anymore).
8332 SilcIDList though still exists. Also, SilcXXXEntry's are
8335 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8337 * Finally made the SKE implementation compliant to the protocol
8338 specification. All mp integers are now binary encoded as
8339 opposed being HEX encoded.
8341 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
8344 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
8345 functions: silc_[encode/decode]_pem. Also added function
8346 silc_encode_pem_file to PEM encode with newlines ('\n') for
8349 * SILC public keys are now encoded either PEM or binary. Same
8350 option is for private keys as well. By default private keys
8351 are binary encoded and public keys PEM encoded. Silly HEX
8352 encoding were removed.
8354 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
8355 function to create fingerprints.
8357 * Fixed a bug in SHA1; does not change the original data anymore.
8359 * Partly implemented INFO command on client and server side.
8360 Fixed CLEAR command. Changes to SERVER command; show current
8361 server(s) when giving command without arguments. Added
8362 VERSION command to client.
8364 * Added check to server that unregistered connections cannot
8365 execute commands (unless it is specificly allowed).
8367 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8369 * Fixed screen refresh.
8371 * Fixed channel joining bug from client. On some circumstances
8372 client tried to join to a channel it had already joined.
8374 * Added public key verification process into client's protocol.c.
8375 The client now verifies the public key from user and saves
8376 it into ~./silc/serverkeys/ directory.
8378 Added into: clientutil.[ch]: silc_client_verify_server_key.
8380 * Changed SKE protocol's silc_ske_initiator_finish function
8381 to accept callback function that verifies the received public
8382 key. Removed old silc_ske_verify_public_key function.
8384 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8386 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
8387 silc_pkcs_private_key[_data]_set.
8389 * Made the password and public authentication more cleaner in
8390 server's protocol.c.
8392 * Removed historic and obsolete protocol `channel_auth' from
8393 both client and server.
8395 * Removed wrong way of sending command status messages from
8396 server to client in server's command.c. The old way violated
8397 protocol specification.
8399 Changes to silccore/silccommand.[ch]: removed
8400 silc_command_encode_status_payload -> not needed anymore,
8401 changed silc_command_encode_payload_va to accept extra
8402 argument on variable argument list. The argument type must
8403 now be provided to the function. Also, added new function:
8404 silc_command_encode_reply_payload_va which is same as
8405 normal command_encode_payload_va except command status type
8406 is provided as extra argument.
8408 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8410 * Added ~./silc directory handling. The directory includes the
8411 public and private keys for the client.
8413 Added silc_client_check_silc_dir, silc_client_create_identifier
8414 and silc_client_load_keys.
8416 * Implemented SILC protocol compliant public key. Added public
8417 and private key saving to and loading from files.
8419 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
8420 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
8421 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
8422 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
8423 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
8425 Implemented: silc_pkcs_save_[public/private]_key[_data] and
8426 silc_pkcs_load_[public/private]_key.
8428 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8430 * Added silc_server_get_route (route.[ch]) to get connection
8431 data for the fastest route for given ID.
8433 * Implemented INVITE command on client and server. The command
8434 were re-defined in the SILC Protocol Specification and the
8435 implementation now complies with the specification.
8437 * Implemented PING command on client and server.
8439 * Implemented NAMES command on client and server. The server side
8440 supports currently only normal server not router server yet.
8441 Some changes to NAMES definition in SILC protocol specification.
8443 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8445 * Implemented LEAVE command on client and server.
8447 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
8448 again. This change was made to the protocol as well. Server
8449 should not violate the protocol specification anymore.
8451 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8453 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
8454 was tested. SOCKS4 was not but should work anyway.
