518 The killer's client entry is now returned to application in
519 the `notify' client operation.
521 * Fixed the Max Argument fields that had too large value set
522 in the protocol specs. Protocol TODO #14.
524 * Added the LEAVE command reply to return the ID of parted
525 channel. Updated protocol specs and implemented it to the
526 client and server. Protocol TODO #15. Affected files are
527 silcd/command.c, lib/silcclient/command_reply.c. The channel
528 entry is now returned to application in the `command_reply'
531 * Rewrote the version SKE version checking in client libary
532 and in server to use the silc_parse_version_string. Affected
533 files are lib/silcclient/protocol.c, silcd/protocol.c.
535 * Added SILC_STATUS_ERR_NO_CHANNEL_FOPRIV error status to few
536 commands that was missing it, and updated protocol specs and
537 the server implementation. Protocol TODO #10. The affected
538 file is silcd/command.c.
540 * Defined new message flags SILC_MESSAGE_FLAG_REPLY to be
541 generic reply to a generic request (REQUEST flag), and
542 SILC_MESSAGE_FLAG_DATA to send any kind of data in a generic
543 way. A draft-riikonen-silc-flags-payloads-00.txt is written
544 to define the payload for DATA flag. Added the flags to
545 the implementation. Protocol TODO #9. Affected file is
546 lib/silccore/silcchannel.h.
548 Changed the client library to return the message length
549 to application as well in the channel_message and private_message
550 client operations. Affected files are
551 lib/silcclient/client_prvmsg, lib/silcclient/client_channel.c,
552 lib/silcclient/silcclient.h, irssi/src/silc/core/client_ops.c,
553 and lib/silcclient/client_ops_example.c.
555 * Added two new channel modes: SILC_CMODE_SILENCE_USERS
556 and SILC_CMODE_SILENCE_OPERS which can be used to moderate
557 the channel. Updated protocol specs and impelemented this
558 to client and server. Protocol TODO #6. Affected files are
559 silcd/packet_receive.c, server_util.c, lib/silcclient/command.c,
560 lib/silcclient/client_channel.c, lib/silccore/silcmode.h.
562 Added new options m and M to CMODE command in Irssi SILC
563 client to set these modes.
565 * Deprecated all administrative commands from SILC protocol
566 since they are highly implementation specific commands.
567 Updated protocol specs. Moved the old commands in
568 implementations to private range of command types. Affected
569 files are silcd/command.c, lib/silcclient/command.c and
570 lib/silcclient/command_reply.c. Protocol TODO #8.
572 * Fixed a bug in server where sending unknown command crashes
573 the server. Affected file silcd/command.c.
575 Wed Apr 3 09:57:47 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
577 * Added SILC_PROTOCOLVERSION macro to check protocol version
578 of a socket connection. The affected file is
579 lib/silcutil/silcsockconn.h.
581 * Added better error logging in rekey protocol. Affected file
584 * Do not check public key types in SKE during rekey. Affected
585 file lib/silcske/payload.c.
587 * Fixed the rekey protocol with PFS, which was totally broken.
588 Affected file silcd/protocol.c.
590 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
592 * Some client implementations quit network by doing first LEAVE
593 and then immediately SIGNOFF (like Bombyx). We now do check
594 after a short time after LEAVE notify and check whether the
595 client is still valid after LEAVE, and if not we remove it from
596 cache. Affected file is lib/silcclient/client_notify.c.
598 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
600 * Merged version 1.1.4 of zlib. Even if it not currently in use,
601 it's good not to have security holes here.
603 * Fixed a negative refcount situtuation for the config context.
604 Affected file is silcd/serverconfig.c.
606 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
608 * ROBOdoc documented lib/silcutil/silcutil.h.
610 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
612 * Optimized even more the SilcPacketContext structure. Now
613 totally saved 16 bytes of memory per context after optimization.
614 Affected files are lib/silccore/silcpacket.[ch].
616 * Made strict checks for valid SILC IDs. Affected file is
617 lib/silccore/silcid.c.
619 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
621 * Changed the object argument for silc_cipher_register,
622 silc_hash_register, silc_hmac_register and silc_pkcs_register
623 to const. Affected files are lib/silccrypt/silccipher.[ch],
624 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
626 * Changed the silc_get_username and silc_get_real_name to
627 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
629 * Fixed the Irssi SILC Client to use the silc_get_username and
630 silc_get_real_name insted of glib routines since the glib
631 routines only corrupt stack. Fixes the Irssi SILC to work in
632 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
634 * Fixed the Irssi to not use g_get_home_dir since it crashes
635 or returns garbage on cygwin and corrupts stack. Added function
636 get_home_dir to Irssi routines. Affected files are
637 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
639 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
641 * Made some structure optimizations. SFTP memory FS MemFSEntry
642 entry structure. Optimized SilcTask structure. Optimized
643 SilcPacketContext structure.
645 Affected files lib/silcsftp/sftp_fs_memory.c,
646 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
648 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
650 * And yet again reverted back the config thing since Johnny
651 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
654 * Fixed memory leaks from config object. Affected files are
655 silcd/serverconfig.[ch].
657 * Added support for adding new connections to the server in rehash.
658 After rehash they take effect.
660 Added support for changing the maximum allowed connections in
661 rehash. The number can grow but going smaller is not supported.
663 Added function silc_server_num_sockets_by_remote to the
664 silcd/server_util.[ch].
666 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
668 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
670 * Added preliminary checking during config parsing for a valid
671 public/private key and removed further checks in the code.
672 Affected files are silcd/serverconfig.[ch], server.c.
674 * Moved functions silc_server_drop() and silc_server_daemonise()
675 from server.c to silcd.c since they are stricly related to
676 the application activity.
678 * Reverted a small part of the automatic ref/unref since
679 it caused a double unref in some situations. Affected
680 files are silcd/silcd.[ch], server.c, serverconfig.c.
682 * Added some .cvsignore files in the lib directory.
684 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
686 * Fixed silc_net_gethostbyaddr to correctly resolve by
687 address. Affected file lib/silcutil/silcnet.c.
689 * Fixed the notify relaying to client. The HMAC to be used
690 with relayed packets ws wrong and caused decryption failure
691 at the client end. Affected file is silcd/packet_receive.c.
693 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
695 * Created new branch silc_protocol_1_0_branch.
697 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
699 * Changed the silc_server_config_* routines to be SilcServer
700 independent. They are now officially application specific code
701 and not part of generic server implementation. Affected files
702 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
704 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
706 * Added automatic referencing of config context in the
707 silc_server_config_alloc, and automatic unreferencing in the
708 silc_server_config_destroy. Affected files are
709 silcd/serverconfig.[ch], silcd/silcd.c.
711 * Fixed the silc_log_quick handling in the logging routines.
712 It didn't log quickly when it was TRUE. Affected file is
713 lib/silcutil/silclog.c. Also the flush delay was set even
714 if it was 0 in config file. Affected file is
715 silcd/serverconfig.c.
717 * Added support for changing key pair of the server in rehash.
718 Affected file silcd/server.c.
720 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
722 * Fixed the TOPIC_SET notify to not cras. It changed the topic
723 too early, before getting the channel entry. Affected file
724 is silcd/packet_receive.c.
726 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
728 * Added functions silc_server_config_[ref/unref], these are used
729 to prevent that the config object is destroyed.
731 No longer directly affect global variables silc_log_quick and
732 silc_log_delay, they are first cached inside the config object
733 and then applied with silc_server_config_setlogfiles().
735 silc_server_config_set_defaults() is now internal to
736 serverconfig.c, there are no reasons to show this internal stuff
739 Affected files are silcd/serverconfig.[ch].
741 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
742 fprintf's to stderr, since some code may be executed again after
743 the server went into the background. Affected files are
746 * Added rehash support. Added function silc_server_rehash() that
747 will perform all the basic tasks of the rehashing procedure.
749 * Added command line option `-x, --hexdump'. This will enable the
750 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
751 The option `--hexdump' implies `--debug'.
753 * Fixed a bad bug in the logging APIs (silcutil library) where
754 the application would crash after calling silc_log_reset_all().
756 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
758 * Fixed the KICKED notify handling in client library to
759 correctly remove the channel and all entries from the
760 channel when I was kicked. This bug crashed the client.
762 Fixed yet another but in KICKED notify handling to remove
763 the kicked client correctly from the channel.
765 Affected file is lib/silcclient/client_notify.c.
767 * Fixed a minor bug in looking up correct client entry
768 in KICKED notify in server. Affected file is
769 silcd/packet_receive.c.
771 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
772 sources correctly to distribution. Fixes --with-gmp option.
774 * Removed the manual rehashing from ID Cache, and changed it
775 to use the SILC Hash Table's auto rehash feature. Affected
776 file is lib/silccore/silcidcache.c.
778 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
780 * Fixed a bug in the silc_client_nickname_format function that
781 handles the multiple same nickname formatting. Two clients
782 with same nickname caused problems after the first one left
783 and rejoined. It didn't format the nickname correctly.
784 Affected file is lib/silcclient/idlist.c.
786 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
788 * Don't change the topic if olod topic is same as new one.
789 Affected file is silcd/packet_receive.c.
791 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
793 * Added cross-reference support to the SILC Documentation
794 generator. All types across all HTML files are now cross-
795 referenced. Affected files util/robodoc/generator.c and
796 scripts/silcdoc/silcdoc.
798 * Added file lib/silcutil/silctypes.h to include all the
799 arithmetic type definitions and some macros. Removed
800 includes/bitmove.h and moved macros to silctypes.h.
802 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
804 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
806 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
808 * Added `type' argument to silc_id_payload_parse_id function which
809 now returns the type of the ID to the sent pointer. Affected
810 file is lib/silccore/silcid.[ch].
812 * Added check for CMODE_CHANGE notify type that mode change is
813 allowed by the sender. Affected file silcd/packet_receive.c.
815 * Added check for CUMODE_CHANGE notify type that mode change is
816 allowed by the sender. Affected file silcd/packet_receive.c.
817 Added the ID type as CUMODE_CHANGE notify type as argument
818 to the `notify' client operation. Affected files are
819 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
821 * Added function silc_client_add_server to the client library.
822 Added support for resolving also channel and server info when
823 received unknown entity in notify packet. Affected files are
824 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
826 * Added function silc_command_get_status to return the command
827 status from the command reply's argument payload. Affected files
828 are lib/silccore/silccommand.[ch].
830 * Added check for KICKED notify type that the kicking is
831 allowed by the client. Affected file silcd/packet_receive.c.
833 * Created function silc_get_input which can be used to get input
834 (echo on or off) from user on command line. Affected files are
835 lib/silcutil/silcutil.[ch].
837 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
839 * Optimized silc_server_packet_relay_to_channel function.
840 Added new function silc_channel_message_payload_encrypt which
841 can be called directly if channel message payload needs to
842 be encrypted and is already encoded (no need to call _encode
843 function). Packet relaying is now done by router without any
844 extra memory allocations. Affected files are
845 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
848 * Fixed the INVITE notify handling. It took wrong arguments
849 as invite list and invite delete. Affected file is
850 silcd/packet_receive.c.
852 * Added check for TOPIC_SET notify type that the topic change is
853 allowed by the client. Affected file silcd/packet_receive.c.
855 * Added check for INVITE notify type that inviting is allowed by
856 the client. Affected file silcd/packet_receive.c.
858 * Changed the silc_server_client_on_channel to return the
859 SilcChannelClientEntry as well. Moved the function
860 silc_server_check_cmode_rights to server_util.[ch].
861 Affected files are silcd/server_util.[ch], silcd/command.c.
863 * Added function silc_server_check_umode_rights to check whether
864 changing client's user mode is allowed. Added check for
865 UMODE_CHANGE notify type that the umode change is allowed
866 by the client. Affected files are silcd/server_util.[ch],
867 silcd/packet_receive.c and silcd/command.c.
869 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
871 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
872 ID length. It ignored that ID can be IPv6 based as well.
873 Affected file lib/silccore/silcpacket.h.
875 * Fixed the silc_id_id2str and silc_id_str2id to take the
876 IPv6 address offset's into consideration. Affecte file is
877 lib/silccore/silcid.c.
879 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
881 * Fixed the internal Unix scheduler functions to check for
882 NULL context they may receive. The affected file is
883 lib/silcutil/unix/silcunixschedule.c.
885 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
887 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
888 can specify different directory with --home command line
889 parameter. Affected files irssi/src/silc/core/client_ops.c,
892 * SILC-specific commands aren't now executed if the active server
893 isn't of SILC-type, so there won't be problems with having
894 IRC and SILC protocol support in same client. Affected files
895 irssi/src/silc/core/silc-channels.c, silc-servers.c,
898 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
900 * Improved the signal support in SILC Schedule. Added new
901 function silc_schedule_signal_call which is used by application
902 to mark a signal to be called. It is now safe to perform
903 any kind of tasks in signal callbacks since it is guaranteed
904 that the application specified signal callback is called
905 after the signal is over. Affected files are
906 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
908 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
910 * Added `name' field to SilcChannelPrivateKey to represent
911 application given name for the key. Moved also the context from
912 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
913 Added the `name' argument also to the function
914 silc_client_add_channel_private_key.
916 Added function silc_client_current_channel_private_key to set the
917 current channel private key in use.
919 Added "change" command to KEY command which can be used to change
920 the current channel private key. Bound the command also to
923 Also affected files lib/silcclient/client_channel.c,
924 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
926 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
928 * Added silc_rng_get_byte_fast function in to the
929 lib/silccrypt/silcrng.[ch].
931 * Changed the interface of silc_packet_assemble and the
932 silc_packet_send_prepare. If silc_packet_assmble is now
933 called the application does not call silc_packet_send_prepare
934 because the library will call it automatically. These
935 interfaces now also return a reference to the outgoing buffer
936 which includes the assembled packet, which the application can
937 use to encrypt the packet.
939 Affected files are lib/silccore/silcpacket.[ch],
940 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
941 silcd/packet_send.c, server_backup.c and packet_receive.c.
943 * Fixed a packet sending bug on very high load, where outgoing
944 packet queue wasn't handled correctly and packets got corrupted.
945 Affected files are lib/silcutil/*/silc*sockconn.c,
946 lib/silcclient/client.c and silcd/server.c.
948 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
950 * Added macro SILC_PACKET_DATALEN which can be used during
951 packet assembling to check whether the data to be added to
952 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
953 len is truncated until it fits it.
955 Added checks for maximum length of channel message payload and
956 private message payload also.
958 Added checks for maximum packet length in server and in
961 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
962 lib/silcclient/client.c, lib/silccore/silcchannel.c and
963 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
964 lib/silcclient/client_prvmsg.c.
966 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
968 * Added silc_server_packet_queue_purge call to the
969 silc_server_disconnect_remote to assure that all data in the
970 queue before disconnecting is sent to the network. Affected
973 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
975 * Added the deleting of server's own ID cache entry to the
976 silc_server_free function. Free also everything else that
977 has been allocated in silc_server_init. The affected file
980 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
982 * Added functions silc_parse_version_string, silc_version_to_num,
983 and silc_ske_parse_version to parse SILC protocol style version
984 strings. Affected files lib/silcutil/silcutil.[ch] and
985 lib/silcske/silcske.[ch].
987 * Added new configuration params: version_protocol, version_software
988 and version_software_vendor to specify what version the remote
989 host must at least be to be able to connect to server. The vendor
990 string can be regex matched too. Added new function
991 silc_server_connection_allowed to check maximum number of allowed
992 connections, and allowed versions for incoming connections.
993 Affected files are silcd/server.c, server_util.[ch] and
996 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
998 * Added preliminary support for signals in scheduler. The
999 signals we care about are now blocked always when the scheduler
1000 is locked. This way we can synchronise the use of signal with
1001 scheduler. It is guaranteed that when signal occurs the scheduler
1002 is not locked, and thus new tasks can be safely added to the
1005 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
1006 to silc_schedule_internal_init and silc_schedule_internal_uninit.
1007 Added new platform specific routines
1008 silc_schedule_internal_signals_[un]block and
1009 silc_schedule_internal_signal_[un]register.
1011 Added new functions to SILC Schedule API:
1012 silc_schedule_signal_[un]register. Each signal that application
1013 is going to use should be registered to the scheduler.
1015 Affected files are lib/silcutil/silcschedule.[ch],
1016 lib/silcutil/*/silc*schedule.c.
1018 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1020 * Check for unauthenticated client and server in the
1021 silc_server_new_client and silc_server_new_server functions.
1022 Affected file silcd/packet_receive.c.
1024 * Added function silc_string_is_ascii to check whether given
1025 string is 7-bit ASCII string. Affected files are
1026 lib/silcutil/silcutil.[ch].
1028 * Added function silc_id_is_valid_server_id into the
1029 silcd/serverid.c and added checking for valid Server ID's in
1030 silc_server_new_server. The Server ID must always be based
1031 on the server's public IP address.
1033 * Added logging of DISCONNECT packet message in the server.
1034 Affected file silcd/server.c.
1036 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1038 * Changed all library interfaces that use Global RNG to also
1039 accept SilcRng as argument. Affected files are
1040 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
1041 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,

1043 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
1044 lib/silccrypt/rsa.c.
1046 * Added function silc_pkcs_generate_key to the
1047 lib/silccrypt/silcpkcs.[ch] for applications so that they
1048 don't need to do pkcs->pkcs->init calls anymore.
1050 * Remove SilcSocketConnection from the SFTP API since it really
1051 wasn't needed there. The application has the information
1052 saved in its contexts anyway and the SFTP layer doesn't need
1053 know about it. Affected files lib/silcsft/silcsftp.h and
1054 lib/silcsftp/sftp_[server/client].c.
1056 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].

1064 algorithm list on EPOC. Affected files are
1065 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
1068 * Fixed the handling of third parameter of KICKED notify, since
1069 it was mistakenly updated to SILC Protocol 1.0 even though it
1070 is to be included in 1.1. Since it is not in 1.0 it is not
1071 mandatory, and this fix now handles it only if it is provided,
1072 and it is not error if it is not provided. Affected file
1073 lib/silcclient/client_notify.c.
1075 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1098 IPv6 bound sockets as well. Now they can return IPv6 addresses
1099 as well. Affected file lib/silcutil/silcnet.c.
1101 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
1102 Affected lib/silcutil/unix/silcunixnet.c.

1110 functions to be used with SilcHashTable. They can be used to
1111 hash public keys and compare public keys in hash table. Affected
1112 file lib/silcutil/silcutil.[ch].
1114 * Added support for specifying multiple public keys for Client
1115 connection section in server configuration file. This makes it
1116 possible to accept multiple public keys from same host, or to
1117 make a section that accepts any incoming host, and have the
1118 accepted public keys listed in the section.
1120 Added functions silc_sever_[find/get]_public_key, added the
1121 support for this actually to all connection sections but only
1122 the Client section is currently allowed to specify multiple
1125 Affected files are silcd/server.c, server_internal.h,
1126 command.c, protocol.c, server_util.[ch], packet_receive.c.

1138 Also fixed some documentation typos.
1140 Affected files are lib/silcutil/silclog.[ch].
1142 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1144 * Fixed the server to check correctly the amount of connections
1145 from single host, by checking also the type of the connection.
1146 Fixed also the comparison of number of connections and number
1147 of allowed connections. Affected files are silcd/server.c,
1150 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1152 * Fixed the USERS command reply to save the user's mode on the
1153 channel as well. Fixed JOIN command reply to check whether a
1154 client is on channel already and not join it twice. Affected
1155 file lib/silcclient/command_reply.c.
1157 * Added new file silc-expandos.c into irssi/silc/core/ to return
1158 various stuff for various signal for the statusbar etc. updating.
1159 Now Irssi SILC client prints channel user modes etc. on the

1202 * Changed all integer type names:
1203 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
1204 to avoid collisions with other libraries using same type names
1207 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1209 * Added `prefer_ipv6' argument to the functions
1210 silc_net_gethostbyname[_async]. If it is TRUE it will return

1226 Wed Feb 20 20:41:01 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1228 * Added automatic extern "C" { ... } for C++ compilers so the
1229 application does not need to define them. Affected file
1230 includes/silcincludes.h.
1232 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
1233 old name went against naming convention. Applications now
1234 include "silcclient.h" instead of "clientlibincludes.h".
1235 Removed includes/clientlibincludes.h, it is redundant now.
1237 * Renamed includes/version.h to silcversion.h.
1239 * Added really preliminary support for OS/2 into the util
1240 library. Only thread & mutex API is implemented, others
1241 are still to be implemented. Created the lib/silcutil/os2/
1242 directory. Created also file includes/silcos2.h.
1244 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1275 * Added `user_count' to the SilcChannelEntry which now tells the
1276 number of users on the channel. The user count is now saved
1277 in normal server of global channels as well. Affected files
1278 silcd/server.c, idlist.h, packet_receive.c and command.c.
1280 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
1281 include file utility functions.
1283 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
1284 instead of calling directly OS routines.
1286 * Fixed NICK change printing in Irssi SILC Client. Fixed
1287 KICKED notify printing in Irssi SILC Client. Affected file
1288 irssi/src/silc/core/client_ops.c.

1294 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1296 * ROBOdoc documented the lib/silcske/silcske.h, and improved
1297 the SKE interface a bit.
1299 * Fixed padding problem in PKCS#1. The padding was not actually
1300 random since the random number generator was used incorrectly.
1301 This security bug affects only when encrypting with PKCS#1, and
1302 it is not currently used at all in SILC. SILC only use signing
1303 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
1305 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1363 is now done in silc_core_init() which also fixes autoconnecting
1366 Affected files irssi/src/silc/core/silc-core.c,
1367 irssi/src/fe-text/silc.c.
1369 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1371 * Added new configuration options and blocks:
1372 keepalive_secs, reconnect_count, reconnect_interval,
1373 reconnect_interval_max, reconnect_keep_trying and
1374 require_reverser_lookup. Added ConnectionParam block, and
1375 implemented the connection parameters when connecting as
1376 initiator and when accepting connections as responder.
1378 Added CONFIG_IS_DOUBLE macro in config file parsing, to check
1379 whether given configuration value has been given already.
1381 Affected files silcd/serverconfig.[c], server.[c].
1383 * Splitted the doc/example_silcd.conf.in. Separated the crypto
1384 algorithm parts and created new file silcalgs.conf, that
1385 is now included from the example_silcd.conf.in.
1387 * Optimized the silc_server_connect_to_router_second to take
1388 the connection configuration object from the SilcServerConnection
1389 object instead of finding it during the connecting phase.
1390 Added the configuration object to SilcServerConnection struct.
1391 Affected files silcd/server_internal.h, server.c.
1393 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1395 * Add the client on channel after it was resolved at the
1396 channel message receiving, and it was not already on the
1397 channel. Affected file lib/silcclient/client_channel.c.
1399 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1415 authentication to be set at the same time.
1417 Added `prefer_passphrase_auth' setting in config file which
1418 can be used to set to prefer passwd auth if both passwd and
1419 public key is set. If not set, public key is preferred.
1420 This has effect only when being initiator (responder will try
1423 Added support for authentication with passphrase and public key
1424 at the same time. The passphrase is tried first always since
1425 it is faster to check.
1427 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
1429 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

1475 * Fixed the file transfer's key agreement payload to include
1476 zero port also if the hostname is NULL because it could not
1479 Call file transfer monitor callback now also if error occurs
1480 during key agreement protocol.
1482 Changed the silc_client_file_send interface to return the
1483 SilcClientFileError instead of session id. The session ID
1484 is returned into pointer provided as argument.

1501 file lib/silcutil/silclog.c.
1503 * Fixed the channel message payload decryption in the function
1504 silc_channel_message_payload_decrypt to not modify the original
1505 buffer before it is verified that the message decrypted

1525 the callback returned.
1527 Do not allow auto rehashing of hash table during the
1528 silc_hash_table_foreach operation, for same reasons as it is
1529 not allowed for SilcHashTableList. Affected files are

1549 from client library.
1551 * Added cross reference of the joined channels to the
1552 SilcClientEntry, and changed the SilcChannelEntry's
1553 users list to SilcHashTable. The affected files are
1554 lib/silcclient/idlist.[ch].
1556 * Fixed a bug in hash table tarversing. While the hash table
1557 is traversed with SilcHashTableList the table must not be
1558 rehashed. It is now guaranteed that auto rehashable tables
1559 are not rehashed while tarversing the list. Also defined that
1560 silc_hash_table_rehash must not be called while tarversing
1561 the table. Added function silc_hash_table_list_reset that must
1562 be called after the tarversing is over. The affected files are
1563 lib/silcutil/silchashtable.[ch].
1565 * Changed all hash table traversing to call the new
1566 silc_hash_table_list_reset in server and in client library.
1568 * Added function silc_client_on_channel to return the
1569 SilcChannelUser entry if the specified client entry is joined
1570 on the specified channel. This is exported to application as
1571 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
1573 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1575 * Fixed founder regaining problem with JOIN command on normal
1576 server. The notify for mode change must be sent always and
1577 not only if !cmd->pending. Affected file silcd/command.c.
1579 * Fixed the WHOWAS command's reply sending to support the
1580 lists correctly. Affected file silcd/command.c.
1582 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1584 * When sending JOIN command to router for processing the
1585 sender's old command identifier was not saved back to the
1586 sender's command context, fixed now. The affected file is
1589 * Create the key in JOIN command of the router did not return
1590 the channel key, added check for this. Affected file is
1593 * Fixed a channel ID update bug in JOIN command reply. Do
1594 not directly upgrade the ID but call the function
1595 silc_idlist_replace_channel_id if the ID was changed.
1596 Affected file silcd/command_reply.c.
1598 * Fixed memory leaks from command calling if it would fail.
1599 Affected file silcd/command.c.
1601 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1603 * Applied patches from cras:
1605 Memory leak fixes around libaries, irssi window resize fix,
1606 new silclist.h and silcdlist.h, all extern inline changed to
1609 * Removed dotconf from lib/dotconf, not needed anymore.
1611 * Removed TRQ from lib/trq, not needed anymore.
1613 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
1614 with server connections. Later this will be configurable
1615 in config file after new config file is done. Affected file
1618 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1620 * Fixed a crash in server related to channel announcements.
1621 Affected file silcd/server.c.
1623 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1625 * Fixed memory leaks in silc_server_create_new_channel*
1626 functions. Affected file silcd/server.c.
1628 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
1629 which ID was changed. This way the router will send the
1630 user list for the channel again, and server won't be in
1631 desync in some rare circumstances. Affected file is
1632 silcd/packet_receive.c.
1634 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1636 * Check for NULL socket pointer in the function
1637 silc_server_packet_send_to_channel_real. Affected file
1638 silcd/packet_send.c.
1640 * Fixed the BAN notify handling to correctly remove ban
1641 list. Affected file silcd/packet_receive.c.
1643 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1645 * Fixed some header addition to Toolkit distribution in
1646 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
1648 * Added lib/silcclient/client_ops_example.h as an template
1649 file for application programmers to quickly start using
1650 the SilcClientOperation functions in their application.
1651 Updated the lib/silcclient/README as well to tell about this
1652 nice file made available.
1654 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1656 * Call silc_server_remove_from_channels when removing client
1657 entry when NO_SUCH_CLIENT_ID was received. Affected file
1658 is silcd/command_reply.c.
1660 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1662 * Added server & router operator statistics updating. Affected
1663 file silcd/packet_receive.c and silcd/command.c.
1665 * Fixed the SERVER_SIGNOFF notify handling on normal server
1666 not to save the history information for clients. Same was
1667 fixed earlier in remove_clients_by_server function, but not
1668 here. Affected file silcd/packet_receive.c.
1670 * Raised the default connection-retry count from 4 to 7 in
1671 server. Affected file silcd/server.h.
1673 * Cancel any possible reconnect timeouts when we start the
1674 key exchange. Affected file silcd/server.c.
1676 * Do not reconnect on connection failure when SCONNECT was
1677 given. Affected files silcd/server.[ch].
1679 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1681 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
1683 * Fixed the NICK command to always give the unformatted
1684 nickname to the one giving the NICK command. If unformatted
1685 nickname is cached already it will be formatted and the
1686 local entry will always get the unformatted nickname.
1687 Affected file lib/silcclient/idlist.c.
1689 * Fixed some double frees from client library commands.
1690 Affected file is lib/silcclient/command.c.
1692 * Fixed CUMODE command in server to assure that no one can
1693 change founder's mode than the founder itself, there was a
1694 little bug. Affected file silcd/command.c.
1696 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1698 * Removed the SilcClientCommandDestructor from the client
1699 libary, it is not needed anymore. Affected files are
1700 lib/silcclient/silcapi.h, command[_reply].[ch],
1701 client_notify, idlist.c.
1703 * Fixed GETKEY command to first resolve client, and then
1704 resolve the server only if the client was not found, instead
1705 of resolving both at the same time. Affected file is
1706 lib/silcclient/command.c.
1708 * Added silc_client_start_key_exchange_cb and lookup the
1709 remote hostname and IP address before starting the key
1710 exchange with server. The affected file is
1711 lib/silcclient/client.c.
1713 * The server's public key is now saved using the IP address
1714 of the server and not the servername for the filename.
1715 The hostname public key filename is checked as an fall back
1716 method if the IP address based filename is not found.
1718 Fixed the GETKEY command to save the fetched server key
1719 in correct filename.
1721 Print the remote server's hostname now when new key is
1722 received during connection process. Affected file is
1723 irssi/src/silc/core/client_ops.c.
1725 * Return always our own public key to the client if it asks
1726 for it with GETKEY command. Affected file silcd/command.c.
1728 * Removed the use_auto_addr variable from default config
1729 file since it was in wrong section. Affected file is
1732 * Fixed TOPIC_CHANGE notification to not route it when it
1733 was sent using silc_server_send_notify_to_channel function.
1734 Affected file silcd/command.c.
1736 * Fixed silc_server_send_notify_kicked to send the kicker's
1737 Client ID also, it was missing. Affected files are
1738 silcd/command.c, silcd/packet_send.[ch].
1740 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1742 * Do not save client history information in SERVER_SIGNOFF.
1743 Fixes the bug in normal server that it does not detect
1744 the client becoming valid after the server becomes back
1745 online. Affected file silcd/server_util.c.
1747 * Added `sock_error' field into the SilcSocketConnection
1748 context. When error occurs during socket operation (read
1749 or write) the error is saved. Added also new function
1750 silc_socket_get_error to return human readable socket error
1751 message. Affected files are lib/silcutil/silcsockconn.[ch],
1752 lib/silcutil/unix/silcunixsockconn.c, and
1753 lib/silcutil/win32/silcwin32sockconn.c.
1755 * The server now prints the socket error message in the
1756 signoff for client. Affected file silcd/server.c.
1758 * Fixed the `created' channel information sending from router
1759 to server in JOIN command. Checks now whether the channel
1760 really was created or not and set it according that.
1762 Fixed the JOIN command to use the client entry's current
1763 ID during the joining procedure instead of the one it sent
1764 in the command (it is checked though), since it can change
1765 between the packet processing and command processing, and
1766 would just case unnecessary pain in the client end. Affected
1767 file silcd/command.c.
1769 * Fixed a channel key payload sending to use correct channel
1770 ID when the server was forced to change the channel's ID by
1771 router. Router sent the key payload with the old Channel ID.
1772 Affected file silcd/packet_receive.c.
1774 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1776 * Call silc_server_save_channel_key only if the key payload
1777 was provided in the JOIN command's command reply. Affected
1778 file silcd/command_reply.c.
1780 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1782 * Fixed silc_mp_sizeinbase to return the value correctly with
1783 MPI. Affected file lib/silcmath/mp_mpi.c.
1785 * Fixed the stop_server signal to correctly stop the scheduler
1786 and gracefully stop the server when SIGTERM or SIGINT signals
1787 are received. Affected file silcd/silcd.c.
1789 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1791 * Simple handling of TERM and HUP signals. Also added some log
1792 flushing call around. Affected file is
1795 * Fixed small bugs in silclog.c. Now buffering output will take
1796 effect after 10 seconds since startup: This will ensure that
1797 no important startup messages are lost. Also output redirection
1798 will preserve original format ([Date] [Type] message).
1799 Affected file is lib/silcutil/silclog.c.
1801 * Added two options to the config file, in the logging section:
1802 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1803 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1805 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1807 * Do not print the warning about log files not being initialized
1808 more than once to avoid excess logging. Affected file is
1809 lib/silcutil/silclog.c.
1811 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1812 the SIM copying in make install in Makefile.am.pre.
1814 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1816 * Rewritten silclog APIs. Globally interesting changes follows:
1817 silc_log_set_files() changed to silc_log_set_file().
1818 silc_log_set_callbacks() changed to silc_log_set_callback().
1819 ROBOdoc documented silclog header file.
1820 SilcLogCb now returns bool to wether inihibit the default
1821 handler or not (to keep the old behaviour return always TRUE).
1822 The new APIs should also fix the problem of the
1823 silcd_error.log file that was written in the current directory.
1826 Log files streams will remain opened after silc_log_set_file()
1827 call, means less CPU usage notably on high traffic servers.
1828 File streams are now full buffered, and flushed to the disk
1829 every 5 minutes, lesses HD activity and CPU usage.
1830 Messages can be redirected, allowing admins to configure
1831 one single logfile for all server messages.
1832 the silc_log_quick global variable to activate fast-logging.
1833 Affected files lib/silcutil/silclog.[ch]
1835 * Changed some code to conform new silclog APIs. Affected
1836 files are doc/example_silcd.conf.in, silcd/server.c
1837 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1840 * Fixed a memory leak that could occur in some situations.
1841 Affected file silcd/serverconfig.c.
1843 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1845 * Added the silc_client_del_client to remove the client from
1846 all channels as well. Affected file lib/silcclient/idlist.c.
1848 * Fixed the client library to correctly remove the client
1849 from all channels when the client entry is being destroyed.
1850 Affected file lib/silcclient/client_notify.c, command.c.
1852 * Added auto-nicking support to the client library. If the
1853 applicatio now sets client->nickname it will be sent to the
1854 server after connecting by the library. This way for example
1855 SILCNICK (or IRCNICK) environment variables will have effect
1856 and always change the nickname automatically to whatever
1857 it is wanted. Affected file lib/silcclient/client.[ch].
1859 * Renamed silc_server_command_bad_chars to the
1860 silc_server_name_bad_chars and moved it to the
1861 silcd/server_util.[ch]. Added also new function
1862 silc_server_name_modify_bad to return nickname that
1863 includes bad characters as new nickname without those
1864 bad characters. This check and modify is now used in
1865 silc_server_new_client when the username is initially set
1866 as nickname, so it must be checked to be valid nickname.
1867 Affected file silcd/packet_receive.c.
1869 * The nickname length is now taken from the packet for real
1870 and not trusted to strlen() since it clearly can return
1871 wrong length for nickname including bad characters. This
1872 also applies to channel names. Affected file silcd/command.c.
1874 * Removed the lib/silcsilm/modules directory. Modules are now
1875 compiled into the lib/silcsim. Fixed the copying of the
1876 modules to follow symbolic links in Makefile.am.pre.
1878 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1880 * Fixed silc_string_regexify list creation. Fixes bugs with
1881 BAN and INVITE commands in server. The affected file is
1882 lib/silcutil/unix/silcunixutil.c.
1884 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1886 * Removed the command destructor entirely from the server's
1887 command and command reply routines. It is not needed, and
1888 its usage was buggy and caused crashes. Affected files are
1889 silcd/command[_reply].[ch].
1891 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1893 * Cancel protocol and NULL sock->protocol if timeout
1894 occurred during protocol. Affected file silcd/server.c.
1896 * Cancel protocol timeouts always before calling the final
1897 callback, to assure that after final callback is called
1898 no other state will be called for the protocol anymore.
1899 Affected file silcd/protocol.c.
1901 * Print error log if incoming connection configuration could
1902 not be found. Affected file silcd/server.c.
1904 * Fixed JOIN command to correctly save the founder mode
1905 to the client on normal SILC server, when the channel
1906 was created by the router. Affected file silcd/command.c.
1908 * Fixed LIST command (hopefully) to send correct reply
1909 packets. Affected file silcd/command.c.
1911 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1913 * The silc_packet_receive_process now returns FALSE if the
1914 read data was invalid packet, and TRUE if it was ok.
1916 The server now checks that if unauthenticated connection
1917 sends data and its processing fails the server will close
1918 the connection since it could be a malicious flooder.
1920 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1922 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1924 * Make sure the warning about error opening a log file is
1925 printed only once and not everytime it fails (produces
1926 too much useless log). Affected file lib/silcutil/silclog.c.
1928 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1930 * Made the silc_server_daemonise() function more readable.
1931 Affected file silcd/server.c.
1933 * Pid file is now optional, the user may comment it out from
1934 the config file. Removed define SILC_SERVER_PID_FILE, we
1935 don't need a default any longer. Affected file
1936 configure.in.pre, lib/Makefile.am.pre.
1938 * Make some use of the pid file. The server now dies at startup
1939 if it detects a valid pid file on his path. The server would
1940 die anyway in this circumstance, because of the bind() failure.
1941 Affected file silcd/silcd.c.
1943 * No longer compiling lib/dotconf.
1945 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1947 * Fixed JOIN command parsing not to crash. Affected file
1948 lib/silcclient/command.c.
1950 * Fied the NICK_CHANGE notify to add the new client entry
1951 even it is resolved. This removes an <[unknown]> nick
1952 thingy bug in the client. Affected file is
1953 lib/silcclient/client_notify.c.
1955 * Do not try to allocate 0 bytes (efence does not like it)
1956 in lib/silccore/silccomand.c when encoding payload.
1958 * Do not take IRCNICK as nickname in Irssi SILC client since
1959 it is not possible to set nickname before hand connecting
1960 the server (TODO has an entry about adding auto-nicking
1963 * Changed the silc_server_command_pending to check whether
1964 there already exists an pending entry with the specified
1965 command, command identifier and pending callback. This is
1966 to fix IDENTIFY and WHOIS related crashes that may register
1967 multiple pending commands with same identifier. Affected
1968 file silcd/command.c.
1970 * Fixed the server to reconnect to the router even if it
1971 was already reconnecting and EOF was received. This to
1972 fix a possibility that the server wouldn't ever try to
1973 auto-reconnect to the router. Affected file silcd/server.c.
1975 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1977 * Fixed the server's password authentication to use the
1978 length of the locally saved password, and not the one
1979 sent in the packet. Affected file silcd/protocol.c.
1981 * Fixed same password authentication problem in the
1982 Authentication Payload handling routines in
1983 lib/silccore/silcauth.c.
1985 * Yet another password authentication problem fixed with
1986 channel password handling in silcd/command.c.
1988 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1990 * If first character of string in silc_parse_userfqdn is '@'
1991 then do not parse it. Affected file is
1992 lib/silcutil/silcutil.c.
1994 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1996 * Fixed minor bug in IDENTIFY command reply sending, which
1997 caused various weird problems during JOIN when it was
1998 resolving names for users. Affected file silcd/command.c.
2000 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2002 * Fixed the IDENTIFY command reply sending to chech better valid
2003 clients. It was possible to send incomplete list of replies.
2004 Affected file silcd/command.c.
2006 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2008 * Added silc_client_command[s]_[un]register functions now to
2009 dynamically register the commands in client library. Removed
2010 the static table of commands. This allows the client library
2011 to call commands without causing the application to know about
2012 what commands library has called.
2014 Removed the INFO command reply kludge to detect when the command
2015 was called by library. Now library use its own command reply
2016 function for INFO command.
2018 Added function silc_client_command_call to call a command.
2019 Application can use it to call command, not access the structure
2022 Now all commands that are sent by the client library (not
2023 explicitly sent by application) use own command reply functions.
2025 Affected files around lib/silcclient/ and in
2026 irssi/src/silc/core/.
2028 * Fixed the WHOIS command reply sending to chech better valid
2029 clients. It was possible to send incomplete list of replies.
2031 Fixed the WHOIS and IDENTIFY to send the request to router
2032 if normal server did not do it and did not find any results.
2034 Affected file silcd/command.c.
2036 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2038 * Moved the internal data from SilcClient context into its
2039 own file, not accesible to application. Affected files
2040 lib/silcclient/client.h and lib/silcclient/client_internal.h,
2041 and other files in client library.
2043 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2045 * Added doc/examples installation target in Makefile.am.pre.
2048 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2050 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
2051 commands the found client entry will be removed from the
2052 cache, after notifying application about the error. Affected
2053 file lib/silcclient/command_reply.c.
2055 * Changed the /MSG to check for exact nickname user gave, and
2056 not let `nick' match `nick@host' if it is only one found. Now,
2057 user must type the exact nickname (like nick@host2) even if
2058 there are no more than one same nicks found. This is to avoid
2059 a possibility of sending nickname to wrong nickname since
2060 `nick' could match `nick@host'. Affected file is
2061 irssi/src/core/silc-servers.c.
2063 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2065 * Do not print "you are now server operator" or similar when
2066 giving /away command. Affected files are
2067 irssi/src/silc/core/client_ops.c, silc-servers.h.
2069 * Made the silc_server_command_pending_error_check to send
2070 the same command reply payload it received back to the
2071 original sender of the command. This way all arguments
2072 that was received by the server will be received by the
2073 client too. Affected file silcd/command.c.
2075 * Added the silc_idcache_add to return the created cache entry
2076 to a pointer. Affected file lib/silccore/silcidcache.[ch].
2078 * Add global clients to expire if they are not on any channel.
2079 This is because normal server will never know if they signoff
2080 if they are not on any channel. The cache expiry will take
2081 case of these entries. This is done by normal servers only.
2082 The affected files are silcd/command_reply.c,
2083 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
2085 * If server receives invalid ID notification for WHOIS or
2086 IDENTIFY and the ID exists in the lists, it is removed.
2087 Affected file silcd/command_reply.c.
2089 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
2090 in client then client entry that it matches is searched and
2091 the nickname is printed on the screen for user. Affected
2092 file irssi/src/silc/core/client_ops.c.
2094 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2096 * Use cache entry expire time in the LIST command reply to
2097 purge old entries from the cache after the LIST command
2098 reply has been received. This way we don't have non-existent
2099 entries in the cache for too long. Affected file is
2100 silcd/command_reply.c.
2102 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2104 * If we are normal server, and we've not resolved client info
2105 in WHOIS or IDENTIFY from router, and it is global client,
2106 we'll check whether it is on some channel. If it is not
2107 then we cannot be sure about its validity and will resolve it
2108 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
2109 file silcd/command.c.
2111 * Search channel by name (if possible) rather than by ID
2112 in IDENTIFY command's command reply. Affected file is
2113 silcd/command_reply.c.
2115 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2117 * Distribute to the channel passphrase in CMODE_CHANGE notify.
2118 Updated specs and implemented it. Affected file silcd/command.c,
2119 silcd/packet_send.c and silcd/packet_receive.c.
2121 * Implemented the <founder auth> payload handling in the JOIN
2122 command. If provided all conditions for channel joining
2123 except requirement to provide correct passphrase can be
2124 overrided by the channel founder. Updated the protocol specs.
2125 Affected file silcd/command.c.
2127 Added support for founder auth in JOIN command in client
2128 library. Fixed the parsing of the JOIN command now to support
2129 all options as they should be. The affected file is
2130 lib/silcclient/command.c.
2132 * Optimized the WHOIS and IDENTIFY commands to send the request
2133 to router only if it includes nicknames or other names. If
2134 they include only IDs then check the local cache first before
2135 routing. Affected file is silcd/command.c.
2137 * Added channels topic announcements. Affected file is
2138 silcd/packet_receive.c and silcd/server.c.
2140 * Fixed the silc_server_send_notify_topic_set to really destine
2141 the packet to channel. Affected file silcd/packet_send.c.
2143 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
2144 library. Affected file lib/silcclient/client_notify.c.
2146 * Added UMODE announcements. Affected file silcd/server.c.
2148 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2150 * Memory leak fixes in:

2157 lib/silccore/silccommand.c
2158 lib/silccore/silcidcache.c
2163 * ROBOdoc documented the lib/silcske/groups.h file and a
2164 bit changed the interface for better.
2166 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2168 * Update the client entry context in the ID cache after
2169 nick change. Affected file lib/silcclient/command.c.
2170 Fixes the CUMODE command when regaining founder privileges,
2171 and a little WHOIS problem.
2173 * Fixed silc_net_gethostbyname to correctly call the
2174 inet_ntop. Affected file lib/silcutil/silcnet.c.
2176 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2178 * Added IPv6 support checking to the configure.in.pre, added
2179 also --enable-ipv6 option to override the check. Affected
2180 file configure.in.pre.
2182 * The silc_thread_create now calls the start function
2183 directly if threads support is not compiled in. Removes
2184 ugly #ifdef's from generic code. Affected files are
2185 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
2187 * Added silc_net_gethostby[name/addr]_async to asynchronously
2188 resolve. Affected files are lib/silcutil/silcnet.[ch].
2190 * Added support for rendering IPv6 based server, client and
2191 channel IDs. Affected file lib/silcutil/silcutil.c.
2193 * Added support for creating IPv6 based server IDs. Affected
2194 file is silcd/serverid.c.
2196 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2198 * Added silc_net_gethostby[addr/name] into the
2199 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
2200 routines. Added silc_net_is_ip[4/6]. Affected file is
2201 lib/silcutil/unix/silcunixnet.c. All routines that take
2202 address as argument now supports both IPv4 and IPv6 addresses.
2204 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2206 * Fixed LIST command reply sending in server. Affected file
2209 * Server now sends the kicker's client ID in the KICK notify
2210 to the kicked client. Affected file silcd/command.c.
2212 * The client library now parses the kickers client ID and
2213 UI displays it. Affected files lib/silcclient/client_notify.c
2214 and irssi/src/silc/core/silc-channels.c, module-formats.c.
2216 * Made all payload parsing function prototypes consistent.
2217 They all take now const unsigned char * and uint32 pair as
2218 the payload data instead of SilcBuffer. Changes all around
2219 the source tree. Other unsigned char* -> const unsigned char*
2220 changes around the tree as well.
2222 * Optimized SFTP client and server packet sending not to
2223 allocate new buffer for each packet but to recycle the
2224 first allocated buffer. Affected files are
2225 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
2227 * Optimized the SFTP client to use SilcList instead of
2228 SilcDList for requests, because it is faster. Affected file
2229 is lib/silcsftp/sftp_client.c.
2231 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
2232 into lib/silccore/silcid.[ch].
2234 Renamed silcpayload.[ch] into silcargument.[ch].
2236 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2238 * If client entry is deleted with active key agreement
2239 session, abort the session.
2241 The silc_client_abort_key_agreement now calls the completion
2242 callback with new SILC_KEY_AGREEMENT_ABORTED status.
2244 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
2247 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2249 * Don't use __restrict in older GCC's. Affected file is
2250 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
2252 * silc_net_localhost now attempts to reverse lookup the
2253 IP/hostname. Affected file lib/silcutil/silcnet.c.
2255 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
2256 command. It can be used to gain founder privileges at
2257 the same time when joining the channel.
2259 Defined that the SILC_NOTIFY_TYPE_KICKED send the
2260 kicker's client ID as well. Updated protocol specs.
2262 Defined that the server must send SILC_COMMAND_IDENTIFY
2263 command reply with error status to client who sent
2264 private message with invalid client ID.
2266 Updated the protocol specification.
2268 * Added silc_server_send_command_reply to send any
2269 command reply. Affected file silcd/packet_send.[ch].
2271 * Added silc_id_payload_encode_data to encode ID payload
2272 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
2274 * The server now send IDENTIFY command reply with error
2275 status if client ID in private message is invalid. Affected
2276 file silcd/packet_receive.c.
2278 * Save the server key file with server's IP address in
2279 the filename instead of hostname. The affected file is
2280 irssi/src/silc/core/client_ops.c.
2282 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2284 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
2287 * Added libtool support for compiling shared objects in
2288 lib/silcsim. Affected file configure.in.pre and
2289 lib/silcsim/Makefile.am. Original patch by cras.
2291 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2293 * Pid file configuration, and server's config file fixes
2294 patch by toma. Updated CREDITS file.
2296 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2298 * Fixed silc_client_channel_message to not try to decrypt
2299 the message twice if it resolved the destination client
2300 information. This could cause of dropping one channel
2301 message. Affected file lib/silcclient/client_channel.c.
2303 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2305 * Added silc_client_run_one into lib/silcclient/silcapi.h and
2306 lib/silcclient/client.c. This function is used when the SILC
2307 Client is run under some other scheduler, or event loop or
2308 main loop. On GUI applications, for example this may be
2309 desired to used to run the client under the GUI application's
2310 main loop. Typically the GUI application would register an
2311 idle task that calls this function multiple times in a second
2312 to quickly process the SILC specific data.
2314 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2316 * Fixed silc_server_drop() for dropping the supplementary
2317 groups as well, this could cause a security hole on some
2320 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2322 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
2325 * Write PID file after dropping privileges. Added -F option
2326 to run server on foreground. A patch by debolaz.
2327 Affected files silcd/server.c, silcd/silcd.c.
2329 * Fixed MOTD to return the MOTD file server name. Affected
2330 file silcd/command.c.
2332 * Added INFO command reply handling to the Irssi SILC Client.
2333 Affected file irssi/src/silc/core/client_ops.c.
2335 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2337 * Fixed the silc_idcache_list_* routines to really support
2338 the dynamic list. Fixes a crash. Affected file is
2339 lib/silccore/silcidcache.c.
2341 * Fixed the LIST command reply to really call LIST command's
2342 pending callbacks. Affected file silcd/command_reply.c.
2344 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2346 * Update conn->local_entry->nickname after giving NICK
2347 command. Affected file lib/silcclient/command.c.
2349 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
2351 * Added the [pid] option to the silcd configuration file
2353 Affected files: serverconfig.[ch] and silcd.c
2355 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2357 * Save fingerprint in WHOIS command reply in server.
2358 Affected file silcd/command_reply.c.
2360 * Fixed NICK commands pending callback registration.
2361 Affected file lib/silcclient/command.c.
2363 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2365 * Use ++server->cmd_ident when sending commands in server,
2366 instead of random number. Affected file silcd/command.c.
2368 * Fixed GETKEY command reply to call actually GETKEY pending
2369 command callbacks. Affected file silcd/command_reply.c.
2371 * A bit stricter check for nicknames. Check for same nickname
2372 in NICK command also. Affected file silcd/command.c.
2374 * Do not call INFO command everytime client ID changes, only
2375 during first connecting. Affected file lib/silcclient/client.c.
2377 * Set the new nickname only after successful command reply for
2378 NICK command is returned by server. Affected file
2379 lib/silcclient/command.c.
2381 * Remove nicknames from nicklist during server_signoff notify.
2382 Should fix /NAMES bit more. The affected file is
2383 irssi/src/silc/core/silc-channels.c.
2385 * Added `fingerprint' field to the SilcIDListData in the
2386 silcd/idlist.h to hold the fingerprint of the client's
2389 Send the fingerprint of the client's public key in WHOIS
2392 Affected files silcd/command.c, and silcd/idlist.[ch].
2394 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
2395 create fingerprint from given data.
2397 * Show the fingerprint of the client's public key in WHOIS.
2398 Affected files irssi/src/module-formats.[ch] and
2399 irssi/src/silc/core/client_ops.c.
2401 * Format the multiple same nicknames also during JOIN and
2402 NICK_CHANGE notifys. Affected file is
2403 lib/silcclient/client_notify.c.
2405 * Do not print error on screen for invalid private message
2406 payload since it can come if someone is sending private
2407 messages with wrong key. Affected file
2408 lib/silccore/silcprivate.c.
2410 * Fixed multiple concurrent /PING crash. Affected file
2411 lib/silcclient/command.c.
2413 * Changed the wrong ID encoding. All IP addresses must be
2414 in MSB first order in encoded format. They were encoded
2415 wrong and was in LSB format. Affected files are
2416 silcd/serverid.c, lib/silcutil/silcutil.c.
2418 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
2420 * Call the `connect' client operation through the scheduler
2421 in case of error. Affected file lib/silcclient/client.c.
2423 * Call the `failure' client operation even if the error
2424 occurred locally during a protocol. Affected file is
2425 lib/silcclient/protocol.c.
2427 * Added support of sending LIST command to router from normal
2428 server. This way normal server can get list of all channels
2429 in the network too. Fixed the channel list sending in the
2430 server too. Affected files are silcd/command.c, and
2431 silcd/command_reply.[ch].
2433 * Added silc_server_update_channels_by_server and
2434 silc_server_remove_channels_by_server. They are used during
2435 disconnection of primary router and in backup router protocol.
2436 Affected file silcd/server_util.[ch], silcd/server.c and
2437 silcd/server_backup.c.
2439 * Fixed channel adding to global list in IDENTIFY command
2440 reply in server. Affected file silcd/command_reply.c.
2442 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2444 * If the incoming packet type is REKEY or REKEY_DONE process
2445 that packet always synchronously. Fixes yet another MAC
2446 failed error on slow (dialup) connections. Affected file
2447 lib/silcclient/client.c and silcd/server.c.
2449 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2451 * Call check_version SKE callback for initiator too. Affected
2452 file lib/silcske/silcske.c.
2454 * Implemented fix for security hole found in the SKE that was
2455 fixed in the specification few days back; the initiator's
2456 public key is now added to the HASH value computation.
2457 Added backwards support for the old way of doing it too, for
2458 old clients and old servers. Affected file is
2459 lib/silcske/silcske.c.
2461 * Enabled mutual authentication by default in SKE. If initiator
2462 is not providing mutual authentication the responder will
2463 force it. This will provide the proof of posession of the
2464 private key for responder. The affected files are
2465 lib/silcclient/protocol.c and silcd/protocol.c.
2467 * Do not cache anymore the server's public key during SKE.
2468 We do mutual authentication so the proof of posession of
2469 private key is done, and if the server is authenticated in
2470 conn auth protocol with public key we must have the public
2471 key already. Affected file silcd/protocol.c.
2473 * Added new global debug variable: silc_debug_hexdump. If
2474 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
2475 file lib/silcutil/silclog.[ch].
2477 * Fixed compilation warning due to char * -> const char *.
2478 Affected files lib/silcutil/silcnet.h, and
2479 lib/silccore/silcauth.[ch].
2481 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2483 * Fixed CMODE command when new channel key was created. If
2484 the creation failed the old key was removed. Next time giving
2485 same command would crash the server since the old key was
2486 freed already. Affected file silcd/command.c.
2488 * Fixed the silc_server_announce_get_channels to not crash
2489 on reconnect. Affected file silcd/server.c.
2491 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2493 * Added silc_log_set_debug_string function to set a regex
2494 string to match for debug output. Only the function names,
2495 or filenames matching the given debug string is actually
2496 printed. This way it is possible to filter out those debug
2497 strings that user is not interested in.
2499 Fixed a bug in silc_string_regexify.
2501 Affected files lib/silcutil/silclog.[ch], and
2502 lib/silcutil/unix/silcunixutil.c.
2504 * Changed the -d options in both server and Irssi SILC client
2505 to take the debug string as argument. Affected files
2506 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
2508 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2510 * Added silc_hash_babbleprint to create a Bubble Babble
2511 Encoded fingerprint. The encoding is developed by Antti
2512 Huima (draft-huima-babble-01.txt), and it creates human
2513 readable strings out of binary data. Affected file
2514 lib/silccrypt/silchash.[ch].
2516 * Print the babble print now in addition of fingerprint as well
2517 in Irssi SILC client. Affected files are
2518 irssi/src/fe-common/silc/module-formats.[ch],
2519 irssi/src/fe-common/silc/core/client_ops.c.
2521 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2523 * Fixed a security problem found in SKE. The initiator's
2524 public key too is now added to the HASH hash value creation
2525 which is signed by the responder to create the SIGN value.
2526 This will prevent anyone in the middle to lie to the responder
2527 about the initiator's public key. If this is done now, the
2528 man in the middle will get caught. Updated the protocol
2531 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2533 * Better installation directory handling. Configure module
2534 paths and other paths automatically to example_silc* files
2535 in doc/. A patch by toma.
2537 * Fixed compiler warning from MPI library, and from SILC RNG.
2540 * Added SILC_SERVER_PID_FILE to define the pid file for server.
2541 It can be configured with ./configure. A patch by toma.
2543 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2545 * Find correct make to use in prepare-clean. A patch by
2546 toma. Affected file prepare-clean.
2548 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
2550 * Added irssi variables use_auto_addr, auto_bind_ip,
2551 auto_bind_port and auto_public_ip.
2553 * Changed the interface for silc_client_send_key_agreement
2554 in lib/silcclient/silcapi.h
2558 irssi/src/silc/core/silc-core.c
2560 lib/silcclient/silcapi.h
2561 irssi/src/silc/core/silc-channels.c
2562 lib/silcclient/client_keyagr.c
2565 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2567 * Added silc_pkcs_public_key_compare to compare two
2568 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
2570 * Check that the client who set the founder mode on the
2571 channel is the same client that is giving the founder
2572 mode to itself. It is done by comparing the saved public
2573 key (it is saved even in the authentication is passphrase).
2574 Affected file silcd/command.c.
2576 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2578 * Do not process packet for disconnected socket connection.
2579 Affected file lib/silccore/silcpacket.c.
2581 * Process the DISCONNECT packet through scheduler in the
2582 client library. Affected file lib/silcclient/client.c.
2584 * Fixed the silc_client_packet_parse to not to increase
2585 the packet sequence number if the conn->sock and the
2586 current socket connection is not same. This can happen
2587 for example during key agreement when the conn includes
2588 multiple socket connections (listeners). Affected file
2589 lib/silcclient/client.c.
2591 * The sender of the file transfer request now provides also
2592 the pointer (listener) for the key exchange protocol. If
2593 the listener cannot be created then it sends empty key
2594 agreement and lets the receiver provide the listener.
2596 Added `local_ip' and `local_port' arguments to the
2597 silc_client_file_send. If they are provided they are used,
2598 if not then it will attempt to find local IP address, if
2599 not found or bind fails then the remote client will provide
2602 Affected files are lib/silcclient/client_ftp.c and
2603 lib/silcclient/silcapi.h.
2605 * Extended the FILE SEND command to support defining the
2606 local IP and port for key exchange listener. They are
2607 optional. Affected file irssi/src/silc/core/silc-servers.c.
2609 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2611 * Defined to WHOIS command reply the sending of fingerprint
2612 of the client's public key (if the proof of posession of the
2613 corresponding private key is verified by the server).
2614 Updated to the protocol specification.
2616 * Added support of receiving the client's public key's
2617 fingerprint in command reply in client library. Affected

2679 silcd/server_util.c.
2681 * Fixed SERVER_SIGNOFF notify handling in the server. The
2682 server is now able to process incoming SERVER_SIGNOFF notify
2683 for a server that it doesn't even know about. It will remove
2684 the clients provided in the notify. Affected file
2685 silcd/packet_receive.c.
2687 * Check for partial packet in data queue after every packet that
2688 was found from the queue. Return and wait for more data if
2689 there is partial data in queue. Affected file is

2730 * Assure that silc_client_notify_by_server_resolve does not
2731 resolve the client information multiple times. If it cannot
2732 be found by the first it cannot be found at all. Affected
2733 file lib/silcclient/client_notify.c.
2735 * Fixed WHOWAS command reply calling. Affected file
2736 lib/silcclient/command_reply.c.
2738 * Removed all references to silc_idlist_get_client from the
2739 Irssi SILC client since that call is internal call used by
2740 the library. The Irssi SILC client will use now client
2741 retrieval functions found in silcapi.h.
2743 * Fixed a bug in resolving nickname info before sending
2744 private message. It used freed memory. Affected file
2745 irssi/src/silc/core/silc-servers.c.

2766 * Added silc_net_localip to return local host's IP address.
2767 Affected file lib/silcutil/silcnet.[ch].
2769 * If key exchange or rekey protocol is active for a connection
2770 parse all packets syncronously since there might be packets
2771 in packet queue that we are not able to process without first
2772 processing packets before them. Affected file silcd/server,

2824 is incomplete and is being resolved, it won't be resolved
2827 Make sure also that USERS command reply does not resolve
2828 twice information. Affected file is
2829 lib/silcclient/command_reply.c.
2831 Make sure that silc_client_get_clients_by_list does not
2832 resolve twice same information.
2834 * Check for valid client->id in the silc_server_free_client_data.
2835 Affected file silcd/server.c.
2837 * Fixed /GETKEY nick@server not to crash if the server entry
2838 is not found. Affected file lib/silcclient/command.c.

2848 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2850 * Call the silc_server_udpate_servers_by_server in the
2851 primary router that comes back online in the backup resuming
2852 protocol. Otherwise it routes packets wrong. Affected file
2853 silcd/server_util.[ch], silcd/server_backup.c.
2855 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2857 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2858 lib/silcutil/silcbuffmt.[ch].
2860 * Redefined the SILC packet header to include the padding
2861 length. Affected file lib/silccore/silcpacket.[ch].
2863 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2864 length for maximum padding up to 128 bytes). Affected
2865 file lib/silccore/silcpacket.h.
2867 * Removed all backwards support for old 0.5.x MAC thingies.
2868 The SILC packet header change makes it impossible to be
2869 backwards compatible.
2871 * Send the ENDING packet with timeout in the backup resuming
2872 protocol. This is to assure that all routers has connected
2873 to the primary router. Affected file silcd/server_backup.c.
2875 * Changed the RNG to take the first IV from random data. It
2876 used to take it from zero actually. Changed the RNG also
2877 to use /dev/urandom during session. /dev/random is used
2878 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2880 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2882 * Changed the SILC packet header to have the first two bytes
2883 (the packet length) encrypted. Affected files aroung the
2884 code tree, lib/silccore/silcpacket.[ch]. Removed the
2885 SilcPacketCheckDecrypt callback. It is not needed anymore
2886 since the silc_packet_receive_process will determine now
2887 whether the packet is normal or special.
2889 * Implemented the unidirectional MAC keys. Affected files
2890 lib/silcske/silcske.c, silcd/protocol.c and
2891 lib/silcclient/protocol.c.
2893 * Implemented the packet sequence number to the MAC computation.
2894 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
2895 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
2896 lib/silcclient/protocol.c.
2898 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2900 * Allow backup router to announce servers. All servers
2901 announced by backup router are added to the global list
2902 automatically. Update hte server's socket to our primary
2903 router also when backup router announces a server.
2904 Affected file silcd/packet_receive.c.
2906 * Do not update the client->router in the function
2907 silc_server_udpate_clients_by_server if the client is on
2908 global list. We might fail to find any specific server
2909 for locally connected clients and local cell clients. They
2910 should still use the `from' and not `to' as client->router.
2911 This fixes backup router resuming protocol. Affected file
2912 silcd/server_util.c.
2914 * Decrease channel statistics count only if the channel
2915 deletion worked. Affected files are silcd/server.c and
2916 silcd/server_util.c.
2918 * Added silc_server_update_servers_by_server to update origin
2919 of all server entries. Used during backup router protocol.
2920 Affected files silcd/server_util.[ch], silcd/server.c. and
2921 silcd/backup_router.c.
2923 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
2924 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
2925 silc_hmac_get_hash and silc_hmac_get_name. Affected file
2926 lib/silccrypt/silchmac.c.
2928 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2930 * Assure that router cannot reroute the same channel message
2931 to the sender. Affected file silcd/packet_receive.c.
2933 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2935 * Made better checks that the channel message is not sent
2936 to the router it came from. Affected file is
2937 silcd/packet_send.c. Fixed memory leak too.
2939 * Announce informations for incoming router connection, but
2940 only after checking if it is replaced by backup router.
2941 Affected file silcd/packet_receive.c.
2943 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2945 * Fixed the backup resuming protocol to work in multiple
2946 router environment. Affected file silcd/server_backup.c.
2948 * Route packet only to one router in the function
2949 silc_server_packet_send_to_channel. Affected file is
2950 silcd/packet_send.c.
2952 * Fixed silc_server_send_notify_dest to set the broadcast
2953 flag. Fixed the silc_server_send_notify_topic to actually
2954 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2955 Affected file silcd/packet_send.c.
2957 * Changed the SFTP Filesystem interface. Changed the
2958 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2959 the filesystem operation function. The SilcSFTPFilesystem
2960 is now a context that is allocated by all filesystem allocation
2961 functions and it already includes the operations structure
2962 and filesystem specific context. It is given as argument
2963 now to the silc_sftp_server_start. This made the interface
2964 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2965 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2967 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2969 * Changed the backup router adding and getting interfaces
2970 in the server. The router that will be replaced by the
2971 specified backup router is now sent as argument. Affected
2972 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2975 * Added silc_net_addr2bin_ne to return the binary form of
2976 the IP address in network byte order. Affected files
2977 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
2979 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2981 * Check for existing server ID in silc_server_new_server
2982 and in silc_server_connect_to_router_final and remove the
2983 old entry if it exists. Affected file silcd/packet_receive.c,
2986 * Send the channel message always to only one router, either
2987 in upstream or downstream. Affected file is
2988 silcd/packet_send.c.
2990 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2992 * Wrote the definition of the backup resuming protocol to the
2993 protocol specification.
2995 * Removed one redundant channel key generation from normal
2996 server during joining procedure. Removed one redundant
2997 channel key sending from server to router during joining
2998 procedure. Affected file silcd/command.c.
3000 * Made minor bugfixes to the backup router resuming protocol.
3001 Affected file silcd/server_backup.c, server.c.
3003 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3005 * Added --disable-asm configuration option. Affected files
3006 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
3009 * Implemented the backup resuming protocol that is used to
3010 resume the primary router position in the cell after the
3011 primary router comes back online. Affected files
3012 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
3013 and silcd/server_util.[ch].
3015 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3017 * Sleep two (2) seconds after sending QUIT command to server.
3018 Affected file lib/silcclient/command.c.
3020 * Assure that if outgoing data buffer is pending do not force
3021 send any data. Affected file silcd/packet_send.c.
3023 * Assure that if outgoing data buffer is pending do not force
3024 send any data. Affected file lib/silcclient/client.c.
3026 * Implemented the backup router support when the primary router
3027 goes down. The servers and routers can now use the backup
3028 router as new primary router without loosing connectivity.
3030 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3032 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
3033 in the server to indicate disabled entry. All data read
3034 from the connection will be ignored and no data is sent
3035 for entry that is disabled. Affected files are
3036 silcd/idlist.h, silcd/server.c.
3038 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3040 * Created SFTP client and server test programs in the
3041 lib/silcsftp/tests directory.
3043 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3045 * Implemented memory filesystem (virtual filesystem) for
3046 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
3049 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3051 * Implemented the SFTP (SSH File Transfer Protocol) to the
3052 lib/silcsftp. It includes SFTP client and SFTP server
3055 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3057 * Moved lib/silccore/silcprotocol.[ch] to the
3058 lib/silcutil library.
3060 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
3061 take variable argument list pointer as argument. Affected
3062 file lib/silcutil/silcbuffmt.[ch].
3064 * Added silc_buffer_set function that is used to set data
3065 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
3066 Affected file lib/silcutil/silcbuffer.h.
3068 * Changed various routines in the core library to use the new
3069 silc_buffer_set instead of allocating new buffer only for
3072 * Added 64-bit value formatting and unformatting support to the
3073 silc_buffer_[un]format routines. Affected file is
3074 lib/silcutil/silcbuffmt.[ch].
3076 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
3077 to includes/bitmove.h.
3079 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3081 * Fixed channel user mode saving in client library. Affected
3082 file lib/silcclient/command[_reply].c.
3084 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3086 * Defined the file transfer to the SILC Protocol. Added
3087 new packet type SILC_PACKET_FTP and defined File Transfer
3088 Payload. The mandatory file transfer protocol is SFTP
3089 (SSH File Transfer Protocol). Affected file in addition
3090 of the internet draft is lib/silccore/silcpacket.h.
3092 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
3093 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
3094 is used as part of backup router protocol when the primary
3095 router of the cell is back online and wishes to resume
3096 the position as primary router.
3098 * Redefined the MAC generation keys in the protocol. The
3099 same key is not used anymore in both direction. Both
3100 direction will now use different keys for sending and
3101 receiving. This fixes a potential security flaw. This
3102 change causes incompatibilities in the protocol.
3104 * Redefined also the MAC computation from the packet.
3105 An packet sequence number is now added to the MAC
3106 computation. This prevents possible replay attacks against
3107 the protocol. This change too causes incompatibilities
3110 Added `sequence' field to the SilcPacketContext to hold
3111 the current sequence number for the packet.
3113 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3115 * Added `created' field to the SilcIDListData in the file
3116 silcd/idlist.h to indicate the time when the entry was
3119 * Added `created' field to the SilcChannelEntry too. Affected
3120 file silcd/idlist.h.
3122 * Added `creation_time' aguments to all the announcement functions
3123 in the server. If it is provided then only the entries that
3124 was created after the provided time frame are actually
3125 announced. Affected file silcd/server.[ch].
3127 * The protocol says that the Channel ID's IP address must be
3128 based on the router's IP address. Added check for this in
3129 the silc_server_new_channel when processing incoming New Channel
3130 Payload. Affected file silcd/packet_receive.c.
3132 * Print out the correct version with --version in SILC client.
3133 Affected file irssi/src/silc/core/silc-core.c.
3135 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3137 * Fixed WHOWAS command to check for completnes of the client
3138 entry always, not just when the command is coming from client.
3139 Affected file silcd/command.c.
3141 * Added new function silc_server_packet_queue_purge to purge the
3142 outgoing data queue to the network. After the function returns
3143 it is guaranteed that the outgoing packet queue is empty.
3144 Affected file silcd/packet_send.[ch].
3146 * Purge the outgoing packet queue in the rekey protocol's final
3147 callback to assure that all rekey packets go to the network
3148 before quitting the protocol. Affected file silcd/server.c.
3150 * Added silc_client_packet_queue_parse as similar function as
3151 in server to the client library. The affected file is
3152 lib/silcclient/client.c.
3154 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3156 * Splitted silcd/server.c and created silcd/server_util.[ch]
3157 for utility functions.
3159 * Added new socket flag SILC_SF_DISABLED to indicate that the
3160 connection is open but nothing can be sent to or received from
3161 the connection. Affected file lib/silcutil/silsockconn.[ch].
3162 The checking for disabled socket is checked in the low level
3163 silc_socket_write and silc_socket_read functions.
3165 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3167 * Allow only nicknames and channel names that fits into the
3168 7-bit unsigned char ASCII set. Affected file silcd/command.c.
3170 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3172 * When processing JOIN command reply in server check that if
3173 the channel exists in our global list we'll move it the local
3174 list. Affected file silcd/command_reply.c.
3176 * Fixed the check whether client is joined on the channel already
3177 in JOIN command. Affected file lib/silcclient/command.c.
3179 * Fixed the JOIN command reply to check whether the channel
3180 already exists. Affected file lib/silcclient/command_reply.c.
3182 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3184 * Added silc_ske_status_string to map the SKE error numbers
3185 to readable strings. The affected files are
3186 lib/silcske/silcske[_status].[ch].
3188 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3190 * Do not show the private channels on the WHOIS channel list
3191 as it is not allowed by the protocol. The affected file is
3194 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3196 * Assure that the packet length digged from the actual packet
3197 is something sensible in the silc_packet_decrypt_rest_special
3198 in lib/silccrypt/silcpacket.c.
3200 * Free and NULL the allocated pointer in silc_hmac_alloc if
3201 the HMAC allocation fails. The affected file is
3202 lib/silccrypt/silchmac.c.
3204 * Print the selected security properties to the log files in
3205 the server. Affected file silcd/protocol.c.
3207 * Add SKE's reference counter even if calling the completion
3208 callback manually. Otherwise it goes negative, although it
3209 does not cause any problems. The affected file is
3210 lib/silcske/silcske.c.
3212 * Remove the client entry with short timeout after giving the
3213 KILL command. Affected file lib/silcclient/command.c.
3215 * Fixed to send error reply in WHOIS and IDENTIFY commands in
3216 case all found clients are already disconnected (WHOWAS would
3217 found them) in the server. Affected file silcd/command.c.
3219 * Update the last_receive (time of last data received) to be
3220 updated only when received private or channel message so that
3221 the idle time showed in WHOIS makes more sense.
3223 * Added boolean field `valid' in to the SilcClientEntry in the
3224 client library to indicate whether the entry is valid or not.
3225 This fixes the nickname change bug on channel when changing
3226 the nickname to be same than the old (like nick to Nick) the
3227 nickname formatter doesn't set the new nick anymore to Nick@host.
3228 Affected file lib/silcclient/idlist.[ch].
3230 * Now actually fixed the nickname changing on disconnection.
3231 Added new function silc_change_nick to the Irssi SILC Client.
3232 Affected file irssi/src/silc/core/client_ops.c,
3233 irssi/src/silc/core/silc-nicklist.[ch].
3235 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3237 * Check that the public key exists in the GETKEY command before
3238 trying to encode it. Affected file silcd/command.c.
3240 * Print some notifications on received public keys with GETKEY
3241 command in the Irssi SILC Client. Affected files are
3242 irssi/src/fe-common/silc/module-formats.[ch],
3243 irssi/src/silc/core/client_ops.c.
3245 * Use IDENTIFY command to resolve the server information in the
3246 GETKEY command instead of INFO command. Affected file
3247 lib/silcclient/command.c.
3249 * All command reply functions in the client library now calls
3250 the pending command reply callbacks even if an error has
3251 occurred. The server has done this a long time and now it was
3252 time to move the client library to this as well. Now all
3253 errors can be delivered back to the pending command reply
3254 callbacks if necessary. Affected files are
3255 lib/silcclient/command[_reply].[ch].
3257 * Change the nickname on disconnection back to the username
3258 because in reconnect the server will enforce it to it anyway.
3259 Affected file irssi/src/silc/core/silc-servers.c.
3261 * Fixed a config file parsing bug in the Irssi SILC client.
3262 Affected file irssi/src/silc/core/clientconfig.c.
3264 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3266 * When printing the channel mode on JOIN, verify that the
3267 channel key and channel's HMAC are valid. Affected file
3268 irssi/src/silc/core/client_ops.c.
3270 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3272 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
3273 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
3274 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
3276 * Removed channel key rekey task deleting from the function
3277 silc_server_save_channel_key. Affected file silcd/server.c.
3278 Added explicit timeout task context instead that is used to
3279 delete the task if we are registering a new task before the
3280 new task has elapsed.
3282 * When channel key rekey occurs the client library now saves
3283 the old channel key for a short period of time (10 seconds) and
3284 is able to use it in case some is still sending channel
3285 messages encrypted with the old key after the rekey. Affected
3286 file lib/silcclient/[idlist.h|client_channel.c].
3288 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3290 * Added check to the silc_server_new_id_real to not accept
3291 new ID if it is the sender's own ID. Affected file is
3292 silcd/packet_receive.c.
3294 * Assure that we do not announce ourself or the one we've
3295 sending our announcements when we're router and are announcing
3296 servers to our primary router. Affected file silcd/server.c.
3298 * Fixed silc_server_command_identify_check_client to assemble
3299 correct WHOIS packet. It send corrupted WHOIS packet and
3300 caused problem with router to router connections. Affected
3301 file silcd/command.c.
3303 Fixed also silc_server_command_whois_check the same way
3304 as for the IDENTIFY command.
3306 * Added new SilcIDListStatus to the server in the SilcIDListData
3307 structure. The status now includes the current status of
3308 the entry (like registered, resolved etc.). Affected file
3309 silcd/idlist.[ch]. Defined a bunch of different status types
3310 as well. This replaced the old boolean registered field as well.
3312 Added resolve_cmd_ident field to the SilcClientEntry structure
3313 too so that if the entry is for example being resolved so
3314 another command may attach to the same pending command reply
3315 without requiring to resolve the same entry again. This concept
3316 should optimize the WHOIS and the IDENTIFY resolving under
3317 heavy load by taking away unnecessary resolving for entries
3318 that are being resolved already.
3320 Added support for adding multiple pending commands for one
3321 command idenfier. Affected file silcd/command[_reply].[ch].
3323 * Fixed WHOIS and IDENTIFY save to remove the cache entry
3324 before deleting the data. Otherwise the hash table will have
3325 freed data in comparison functions. Affected file is
3326 silcd/command_reply.c.
3328 * Fixed silc_idlist_replace_client_id to add the new entry to
3329 the cache with NULL nickname. Otherwise there will be invalid
3330 memory as the nickname after the nickname is freed. Affected
3331 file silcd/packet_receive.c.
3333 * Fixed the silc_idlist_get_clients_by_hash. The entries was
3334 saved into wrong slots because the previous number of entries
3335 was not taken into account. Affected file silcd/idlist.c.
3336 Fixed same thing in silc_idlist_get_clients_by_nickname too.
3338 * If we are router and we receive JOIN notify to a channel that
3339 does not have any users then notified client is marked as the
3340 channel founder, as it is it. The affected file is
3341 silcd/packet_receive.c
3343 * Added to the extended hash table API's table_del_*ext functions
3344 the destructor as argument too, so that the caller can decide
3345 which destructor to use or whether to use destructor at all.
3346 Affected file lib/silcutil/silchashtable.[ch].
3348 * Fixed ID Cache purging. It actually deleted the entries from
3349 the hash table after the data was freed. The hash table ended
3350 up comparing freed memory. The affected file is
3351 lib/silccore/silcidcache.c.
3353 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3355 * Fixed Irssi SILC client's KILL command's HELP syntax.
3357 * The USERS command now resolves the detailed user information
3358 if the userinfo field is missing. Affected file is
3359 lib/silcclient/command_reply.c.
3361 * Do not print error in silc_file_read if the read file does
3362 not exist. Just silently return NULL. Affected file is
3363 lib/silcutil/silcutil.c.
3365 * Fixed the silc_log_output to not wine about NULL filename
3366 and to not create some bogus " " filename. Affected file is
3367 lib/silcutil/silclog.c.
3369 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3371 * Fixed various printing bugs on the user interface in the
3372 Irssi SILC Client. Minor changes that were forgotten from
3375 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3377 * Fixed the configure.in.pre and the compilation and distribution
3378 environment to support the new autoconf 2.52. That version is
3379 now required to compile the CVS trunk.
3381 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3383 * Renamed function silc_parse_nickname to silc_parse_userfqdn
3384 to generally parse user@fqdn format strings. Affected file
3385 lib/silcutil/silcutil.c.
3387 * Added nickname_format and nickname_force_format fields to the
3388 SilcClientParams structure. The first one defines the format
3389 for the nicknames that the library will enforce if the receives
3390 multiple same nicknames. The second one is boolean value and
3391 can be used to force the library to always enforce the format
3392 to the nicknames regardles whether there are multiple nicknames
3393 or not. This configurable formatting was employed to flexibly
3394 support accessing multiple nicknames from the user interface.
3395 The userinterface can now set the nicknames to what ever format
3396 they prefer. Affected file lib/silcclient/silcapi.h.
3398 Added function silc_client_nickname_format to the file
3399 lib/silcclient/idlist.c. It performs the nickname formatting.
3401 Added new field `hostname´ to the SilcClientEntry context.
3402 It holds the hostname of the client. Affected file is
3403 lib/silcclient/idlist.h.
3405 * Irssi SILC Client sets the nicknames in nick@hostn format.
3406 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
3407 irssi/src/silc/core/silc-core.c.
3409 The WHOIS printing now also shows both the real nickname and
3410 the formatted nickname so that user knows how to access the
3411 user if there are multiple same nicknames cached. Affected
3412 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
3413 printing formatting too to take the hostname now as a separate
3414 argument. The Affected file is
3415 irssi/src/fe-common/silc/modules-formats.[ch].
3417 * Changed the silc_client_get_clients_local to accept the formatted
3418 nickname as argument. It accepts the real nickname too but the
3419 formatted nickname can be used to find the true entry from
3420 multiple entries. Affected file lib/silcclient/silcapi.h and
3421 lib/silcclient/idlist.c.
3423 * Added nickname_format_parse field to the SilcClientParams.
3424 It is a callback function provided by the application to parse
3425 the nickname out of the formatted nickname string. The library
3426 calls it to get the nickname from the formatted string. Since
3427 the application generally knows better the format of the nickname
3428 string it parses it instead of the library, even though library
3429 encodes the formatted string. If the callback function is not
3430 provided then the library will use the string as is. The
3431 affected file is lib/silcclient/silcapi.h.
3433 * All the nickname strings passed to the client library in
3434 commands are now expected to be formatted nickname strings.
3435 If the command does not support the formatted nickname string
3436 it will assume that the sent string is the actual nickname.
3437 Affected file lib/silcclient/command.c.
3439 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3441 * Added public key authentication support to OPER and SILCOPER
3442 commands in the client library. Affected file is
3443 lib/silcclient/command.c.
3445 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3447 * Changed the get_auth_methdod client operation to be asynchronous.
3448 It can be async if the application resolves the authentication
3449 method from the server during the negotiation. Added new
3450 SilcGetAuthMeth completion callback that the application will
3451 call after resolving the authentication method.
3453 Added function silc_client_request_authentication_method that
3454 the application can use to resolve the authentication method
3455 from the server. Added also SilcConnectionAuthRequest callback
3456 that the library will call after the server has replied. The
3457 application can call this function if it does not know the
3458 current authentication method.
3460 Affected files are lib/silcclient/client.c and
3461 lib/silcclient/silcapi.h.
3463 * The Irssi SILC client now automatically resolves the authentication
3464 method incase any configuration information is not present (and
3465 currently there never is). The affected file is
3466 irssi/src/silc/core/client_ops.c.
3468 * Fixed public key authentication from the client library.
3469 Affected file lib/silcclient/protocol.c. Changed also the
3470 protocol specification about the public key authentication in
3471 the connection authentication protocol. The actual data to be
3472 signed is now computed with a hash function before signing.
3474 * Fixed the public key authentication from the server as well.
3475 Affected file silcd/protocol.c.
3477 * Removed the mlock()'s from the memory allocation routines.
3478 Affected file lib/silcutil/silcmemory.c. The ./configure does
3479 not check anymore for the mlock(). Affected file is
3482 * Fixed USERS command in server to allow the execution of the
3483 command for private and secret channels if the client sending
3484 the command is on the channel. Affected file silcd/command.c.
3486 * Fixed silc_client_get_clients_local to return the clients
3487 count correctly. It could return wrong value. Affected file
3488 lib/silcclient/idlist.c.
3490 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3492 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
3493 types. The assembler optimizations seemed not to like 64-bit
3494 data types. The assmebler optimizations thus are now enabled
3495 also for BSD systems as opposed to only enable them for Linux.
3497 * Do not check for threads at all on BSD systems. Affected
3498 file configure.in.pre.
3500 * Removed -n and -h options from the Irssi SILC Client since
3501 they are not used in silc.
3503 * Fixed the prime generation to assure that the first digit
3504 of the generated random number is not zero since our conversion
3505 routines does not like number strings that starts with zero
3506 digit. If zero digit is seen the random number is regenerated.
3507 This caused some corrupted RSA keys when the zero first digit
3508 was met. Affected file lib/silcmath/silcprimegen.c.
3510 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3512 * Fixed WIN32 configuration in the ./configure script.
3513 Fixed to include xti.h on environments that has it.
3514 Patches by Carsten Ilchmann and andrew.
3516 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3518 * Changed the silc_id_create_client_id to be collision
3519 resistant. It is now assured that there cannot be created
3520 two same client ID's. I suspect that some weird bugs in
3521 the server were actually caused by duplicate Client IDs.
3522 Affected file silcd/serverid.[ch]. A router receiving
3523 new ID now also assures and informs the sending server
3524 if the ID caused collision.
3526 * Changed the silc_id_create_channel_id to also assure that
3527 there are no collisions.
3529 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3531 * Statement about ignoring the Mutual Authentication flag when
3532 performing rekey with PFS was a bit misleading. It is ignored
3533 if it was set in the initial negotiation, it cannot be even
3534 set in the rekey. Fixed in the ke-auth draft. Started the
3535 new versions of the protocol drafts in the doc/.
3537 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3539 * Fixed a bug in silc_client_command_identify_save when saving
3540 new channel information. The channel name was no duplicated
3541 and caused crash on exit. Affected file is
3542 lib/silcclient/command_reply.c.
3544 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3546 * Fixed the getkey command handling in the server. Send just
3547 empty OK reply to the sender if the key could not be fetched
3548 (but everything else was ok, like the key just was not available).
3549 Changed the public key parameter to optional in the protocol
3550 specs so that empty OK reply can be sent. Affected file
3553 Added a message to Irssi SILC client to tell to user if the
3554 server did not return a public key.
3556 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3558 * Fixed a channel key regeneration bug. It registered new
3559 timeout tasks exponentially until all system resources were
3560 used. Affected file silcd/server.c.
3562 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3564 * Added the SILC Document generator to the scripts/silcdoc.
3565 It can be used to generate the Toolkit Reference Manual out
3566 of the source tree. Internally it will also use the RoboDoc
3567 generator now imported in util/robodoc.
3569 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3571 * Added couple of return's in rekey protocol if error orccurred
3572 during the protocol. The execution must be terminated.
3573 Affected file silcd/protocol.c. Also, terminate the protocol
3574 always with timeout.
3576 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3578 * The client's Client ID was created initally from the wrong
3579 nickname (it could have been in format nick@host) in the
3580 silc_server_new_client. Affected file silcd/packet_receive.c
3582 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3584 * Added some SILC_LOG_ERROR's to various error conditions
3585 if client could not be added to ID cache. Affected files
3586 silcd/packet_receive.c and silcd/server.c.
3588 * When client's sock->user_data is freed, NULL also the
3589 client->router and client->connection pointers. Added check
3590 for these pointers being NULL to various places around the
3591 code. Affected file silcd/server.c.
3593 * Added client->data.registered == TRUE checks to various
3594 places around the code to assure that unregistered client's
3595 are not handled when it is not allowed. Affected file
3598 * Added `bool registered' fields to all
3599 silc_idlist_[server|client]_get_* routines to indicate whether
3600 the fetched client needs to be registered or not. Affected
3601 file silcd/idlist.[ch].
3603 * Add your own entry as registered to the ID cache in the
3604 server. Affected file server.c.
3606 * Fixed a bug in silc_server_new_server. The SilcServer was
3607 set as the new server's context instead of SilcServerEntry.
3608 This naturally caused some weird bugs.
3610 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3612 * Do not delete the channel rekey task when adding it
3613 for in silc_server_create_channel_key.
3615 * Changed the silc_server_create_channel_key to return
3616 TRUE or FALSE to indicate the success of the channel key
3619 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3621 * Fixed MSVC++ project files and added missing files to
3622 Makefiles under win32/.
3624 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3626 * Do not add TCP_NODELAY flag if the operating system
3627 does not have it defined. Affected files are
3628 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3630 * Fixed buffer overflow from Irssi SILC Client. Affected
3631 file irssi/src/fe-common/core/themes.c.
3633 * Fixed double free in client library in the file
3634 lib/silcclient/client.c when disconnecting from server.
3636 * Applied double free patch from cras to Irssi SILC client.
3637 Affected files irssi/src/core/[modules/expandos].c
3639 * Fixed the disconnection handling to Irssi SILC Client.
3640 The application must call silc_client_close_connection
3641 in ops->connect client operation in case of failure of
3642 the connection. Affected file is
3643 irssi/src/silc/core/client_ops.c.
3645 * Do not set sock->protocol to NULL in the function
3646 silc_client_close_connection after executing the protocol's
3647 final callback since the sock might not be valid anymore.
3648 Affected file lib/silcclient/client.c.
3650 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3652 * Do not enable SILC_THREADS if the linking with libpthread
3653 did not happen. Affected file configure.in.pre.
3655 * Added notion to protocol specification that server must
3656 verify the sent authentication payload with CMODE when
3657 setting the channel founder key. Implemented it to the
3658 server. Affected file silcd/command.c.
3660 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3662 * Added _EXTRA_DIST SILC distribution variable to the
3663 distributions file. It is used to conditionally add extra
3664 files or directories to the specific distribution. Affected
3665 files ./prepare, Makefile.am.pre and distributions.
3667 Removed the `_' from the start of the distribution names.
3670 * Added README.WIN32 for instructions to compile the Toolkit
3673 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3675 * Fixed a double free in disconnection in the server. Affected
3676 file is silcd/server.c.
3678 * Fixed the lib/silcske/groups.c to work now also with GMP
3679 MP library. The string conversion did not work when using
3680 specific base and the base is indicated in the string as well.
3682 * Created win32/ directory which now includes MSVC++ specific
3683 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3684 It will appear only in the toolkit distribution
3686 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3688 * Changed the key material distribution function in case when
3689 the hash output is too short. The data is now concatenated
3690 a bit differently than it used to. Made the change to the
3691 SKE protocol specification.
3693 * Added better GMP detection to configure.in.pre. A patch
3696 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3698 * Fixed a minor bug in SKE that might cause some problem on
3699 some platforms. Affected file lib/silcske/silcske.c.
3701 * Added the cookie checking for initiator in the SKE. It checks
3702 that the responder returns the sent cookie unmodified. The
3703 affected file is lib/silcske/silcske.c. Added new SKE
3704 error type INVALID_COOKIE that can be sent during the
3705 negotiation. Fixed some memory leaks as well.
3707 * Added the "invalid cookie" error message to Irssi SILC client's
3710 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3712 * Added `task_max' field to the SilcClientParams to indicate
3713 the maximum tasks the scheduler can handle. If set to zero,
3714 default values are used. Affected file lib/silcclient/silcapi.h.
3716 * Fixed memory leaks in silc_client_close_connection. Affected
3717 file lib/silcclient/client.c.
3719 * Added silc_client_del_client_entry to client library to free
3720 all memory of given client entry. Affected file is
3721 lib/silcclient/idlist.[ch].
3723 * Added new functions silc_client_del_channel and
3724 silc_client_del_server to delete channel and server entries.
3725 Affected file lib/silcclient/[silcapi.h/idlist.c].
3727 * Removed silc_client_del_client_by_id from silcapi.h.
3729 * Fixed the INFO command to return the server's own info
3730 correctly when querying by Server ID. Affected file is
3733 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3735 * Removed the non-blocking settings in WIN32 code in the
3736 silc_sock_[read/write] and added SleepEx instead. Affected
3737 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3738 of input data is now checked with FIONREAD and ioctlsocket.
3740 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3742 * Call silc_schedule_task_del_by_context in the
3743 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3744 Affected file lib/silccore/silcprotocol.c.
3746 * Call silc_protocol_cancel for active protocols in the
3747 silc_server_close_connection if the funtion
3748 silc_server_free_sock_user_data has not been called.
3749 Affected file silcd/server.c.
3751 * Generic tasks cannot be deleted using the del_by_fd
3752 task deleting function since generic tasks does not match
3753 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3755 * Added a notion to SILCOPER help file that the SILCOPER works
3756 only on router server, not on normal server.
3758 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3760 * Added for WIN32 support for the new scheduler as well.
3761 Affected file lib/silcutil/win32/silcwin32schedule.c.
3763 * Fixed the SHA1 implementation to work on various platforms.
3765 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3767 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3768 API. It is part of the scheduler now. Everything else is
3769 as previously but some functions has changed their names.
3770 Checkout the lib/silcutil/silcschedule.h for the interface.
3771 Updated all applications to use the new interface. Affected
3772 files are lib/silcutil/silcschedule.[ch].
3774 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3776 * Found a bug in the SKE implementation. The HASH value,
3777 specified by the protocol, was not computed correctly. The
3778 public key of the responder was not added to the computation
3779 even though it is mandatory. Affected file lib/silcske/silcske.c.
3780 This unfortunately causes incompatibilities with older
3781 clients and servers.
3783 * Added WIN32 specific network init and uninit functions:
3784 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3785 the Winsock2. Affected file lib/silcutil/silcnet.h and
3786 lib/silcutil/win32/silcwin32net.c.
3788 * Set the socket always to nonblocking mode on WIN32 after
3789 reading data or writing data. Affected file is
3790 lib/silcutil/win32/silcwin32sockconn.c.
3792 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3794 * Fixed various compilation problems under WIN32. Affected
3795 files lib/silcutil/win32/silcwin32thread.c and
3796 lib/silcutil/win32/silcwin32schedule.c.
3798 * Removed all _internal.h #includes from public header
3799 files. Internal headers must never be included from
3802 Removed also the lib/silcske/payload_internal.h file.
3804 * All include files that may be needed (public and some others
3805 included by the public headers) by application developers are
3806 now copied to the ./includes directory. It does not copy any
3807 internal headers. Affected file Makefile.defines.pre and all
3808 Makefile.am's under lib/ and subdirs.
3810 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3812 * Do not change the ~/.silc directory's permissions automatically.
3813 Affected file irssi/src/silc/core/clientutil.c.
3815 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3817 * Do not cancel the protocol in silc_server_close_connection
3818 it might cause recursion. Now cancelled in the function
3819 silc_server_free_sock_user_data. Affected file silcd/server.c.
3821 * Fixed the silc_server_remove_clients_by_server to regenerate
3822 the channel keys correctly finally. Added also new function
3823 silc_server_remove_clients_channels to actually do it.
3824 Affected file silcd/server.c.
3826 * Fixed the silc_server_new_channel to not crash by giving
3827 wrong router to the new channel. Affected file is
3828 silcd/packet_receive.c.
3830 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3832 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3833 which is given as argument to the silc_client_alloc now.
3834 It can be used to configure the client and set various parameters
3835 that affect the function of the client.
3837 * The USERS command in server did not check whether the channel
3838 is private or secret. Affected file silcd/command.c.
3840 * Added new argument to the USERS command in protocol specification.
3841 The USERS command now can take the channel name as argument
3842 as well. Added support for this in client and server and
3843 updated the protocol specs.
3845 * Completed the GETKEY command in client. It can be now used
3846 to fetch also servers public key not only some clients.
3847 Affected files lib/silcclient/command[_reply].c.
3849 * Added silc_client_get_server to return server entry by the
3850 server name. Affected files lib/silcclient/silcapi.h and
3853 * Redefined the IDENTIFY command in protocol specification to be
3854 more generic. It now can be used to query information about
3855 any entity in the SILC Network, including clients, servers and
3856 channels. The query may be based either the entity's name
3857 or the ID. Added support for this in both client and server.
3859 Affected files silcd/command.c and lib/silcclient/command.c
3860 and command_reply.c.
3862 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3863 the _from_client and _from_server functions. Affected file
3866 * Added silc_client_get_channel_by_id_resolve to the file
3867 lib/silcclient/silcapi.h to resolve channel information by
3868 its ID. Added also silc_client_get_channel_by_id that
3869 does not resolve it from the server.
3871 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3873 * Added SilcServerEntry context into the client library
3874 to represent one server. The INFO command now allocates
3875 these to save the resolved server info. For now on the
3876 client library will also keep information about servers,
3877 connected and resolved with INFO.
3879 The INFO command now allocates the SilcServerEntry context
3880 and saves the server info there. The COMMAND_REPLY in
3881 the INFO now returns the parameters to application in
3882 same order as defined in the protocol specification.
3884 The entries are cached in the client->server_cache.
3886 * The INFO command is now issued after received the Client ID
3887 from the server. Affected file lib/silcclient/client.c.
3889 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3890 to the application as the mode changer might be server.
3891 It is guaranteed that NULL is not returned anymore to the
3892 application. Affected file lib/silcclient/client_notify.c.
3894 The ID Type is now also passed to the application so that
3895 it can check whether the returned entry is SilcClientEntry
3898 Added new function silc_client_get_server_by_id to return
3899 the server entry by ID. Affected files are the
3900 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3902 * Do not create the channel in the Irssi SILC Client when issuing
3903 the JOIN command but when received the sucessful JOIN command
3904 reply. Otherwise the channel might get created even though we
3905 could not join it. The Affected file is
3906 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3908 * Fixed a channel joining bug in router. The router must also
3909 check the channel modes, invite and ban lists etc. when serving
3910 the JOIN command sent by normal server. Affected file is
3911 silcd/command.c. The router now resolves the client's
3912 information from the server who sent the JOIN command if it
3913 does not know it, and processes the JOIN command only after
3916 * Changed the SilcCommandCb to take new argument; void *context2.
3917 Affected file lib/silccore/silccommand.h
3919 The second argument in the command callbacks in the server now
3920 includes the SilcServerCommandReplyContext if the command was
3921 called as pending command callback from the command reply.
3922 Otherwise it is NULL. When called as pending the status of the
3923 command reply will be checked and if it was erronous the
3924 error will be sent to the original sender of the command.
3925 This way the client always receives the error messages even
3926 though the server was actually the one who received the error
3927 when it resent the command to router, for example. Affected
3928 files silcd/command[_reply].[ch].
3930 * Fixed sending WHOWAS command's error message to client if
3931 the requested client could not be found. It was missing.
3934 * Changed the CMODE and CUMODE commands reply arguments in the
3935 protocol specification. The Channel ID is now sent in both
3936 of the commands to identify the channel. Implemented this
3937 new feature to the client and server. Affected files
3938 lib/silcclient/command_reply.c and silcd/command.c.
3940 * Made better checks for invite and ban lists in the JOIN
3941 command in server. Affected file silcd/command.c.
3943 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3945 * The server now performs the incoming host IP/DNS lookup
3946 using the silc_socket_host_lookup and thus does not block
3947 the server anymore. Affected file silcd/server.c.
3949 * Completed the multi-thread support for SILC Scheduler in
3950 the lib/silcutil/silcschedule.c.
3952 * Fixed the configure.in.pre to detect the pthread correctly
3955 * Fixed a deadlock in silc_task_queue_wakeup in the file
3956 lib/silcutil/silctask.c.
3958 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3960 * Added new function silc_schedule_wakeup that is used in
3961 multi-threaded environment to wakeup the main thread's
3962 schduler. It needs to be used when a thread adds a new task
3963 or removes a task from task queues. After waking up, the
3964 scheduler will detect the task queue changes. If threads
3965 support is not compiled in this function has no effect.
3966 Implemented the wakeup mechanism to both Unix and WIN32
3967 systems. Affected files are lib/silcutil/silcschedule.[ch],
3968 lib/silcutil/unix/silcunixschedule.c and the
3969 lib/silcutil/win32/silcwin32schedule.c.
3971 * Added new function silc_task_queue_wakeup to wakeup the
3972 scheduler by the specified task queue. Affected file
3973 lib/silcutil/silctask.[ch].
3975 * The silc_socket_host_lookup_start now wakes up the scheduler
3976 after adding the timeout task. Affected file is
3977 lib/silcutil/silcsockconn.c.
3979 * The silc_socket_host_lookup is synchronous now if the threads
3980 support is not compiled in. However, the callback is still
3981 called asyncronously through the scheduler, anyway. Affected
3982 file lib/silcutil/silcsockconn.c.
3984 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3986 * Added new function silc_socket_host_lookup to perform
3987 asynchronous IP and FQDN lookups for the socket connection.
3988 Affected files lib/silcutil/silcsockconn.[ch].
3990 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3992 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3993 that may or may not compile the mutex support in.
3995 Changed the silc_mutex_alloc interface. It allocates the
3996 mutex now to the sent pointer and returns TRUE or FALSE.
3998 Affected file lib/silcutil/silcmutex.h.
4000 * Wrote the SILC Task Queue interface to support multi-threads.
4001 Affected file lib/silcutil/silctask.[ch].
4003 * Wrote the SILC Scheduler to support multi-threads. Affected
4004 file lib/silcutil/silcschedule.c.
4006 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4008 * Implemented the SILC Mutex API and SILC Thread API for WIN32
4009 in lib/silcutil/win32/.
4011 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4013 * Defined SILC Mutex API and SILC Thread API and implemented
4014 them for Unix. Affected files are
4015 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
4016 lib/silcutil/unix/silcunixmutex.c and
4017 lib/silcutil/unix/silcunixthread.c.
4019 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4021 * Fixed the silc_server_remove_clients_by_server's channel
4022 key re-generation. The hash table handling was incorrect
4023 and would not work with many channels. Affected file is
4026 * Fixed some memory leaks around the server code.
4028 * Rewrote the silc_server_get_users_on_channel to support IPv6
4029 based Client ID's. Affected file silcd/server.c.
4031 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
4032 specification. However, a separate document must be written
4033 to define the detailed signing procedure and the payload
4034 associated with the flag. Defined the flag to the
4035 lib/silccore/silcchannel.h as well.
4037 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4039 * Changed the dynamic tables to static size tables in the
4040 lib/silccrypt/silchmac.c.
4042 * Removed GCC dependencies from the code. A patch by cras.
4044 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4046 * Do not show the error "Error receiving packet bla bla"
4047 in server if it really was not an error (-2 means that reading
4048 is pending). Affected file silcd/server.c.
4050 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4052 * Fixed a possible crash in silc_server_remove_clients_by_server
4053 in silcd/server.c. Fixed there also some memory leaks.
4055 * Fixed the silc_idlist_replace_client_id. It could replace
4056 wrong key in the hash table. Affected file silcd/idlist.c.
4058 * Do not check whether there are global users on the channel
4059 if the channel->global_users is FALSE. Affected functions
4060 silc_server_remove_from_one_channel and
4061 silc_server_remove_from_channels in silcd/server.c. Also,
4062 do not check if the removed client is local as we can be
4063 sure that global client was not removed from the channel
4064 and checking for global users is not needed.
4066 * The silc_server_remove_clients_by_server now re-generates
4067 the channel keys correctly for those channels that had
4068 clients removed from them. Affected file silcd/server.c.
4070 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4072 * Found the reason of random crashes in the server. We weren't
4073 ignoring the SIGPIPE signal (which can be sent in write())
4074 and it crashed the server. Affected file silcd/silcd.c.
4076 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4078 * Assure that sock->user_data is not NULL in the function
4079 silc_server_packet_send in silcd/packet_send.c.
4081 * Disconnect the remote connection if it could not be added
4082 to any ID lists in the server. The affected file is
4085 * Check in silc_server_packet_send[_real/dest] that the
4086 socket is not disconnecting and ignore the data if it is.
4087 Affected file silcd/packet_send.c.
4089 * Define inline to __inline on native WIN32 compilation.
4090 Affected file includes/silcwin32.h.
4092 * Added some explicit type casts for inline code since MSVC
4093 require them. Affected files lib/silcutil/silcbuffer.h,
4094 lib/trq/silcdlist.h and lib/trq/silclist.h.
4096 * Print warning in log files from now on if the packet
4097 decryption fails. Affected file silcd/server.c.
4099 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4101 * Changed the `say' client operation's interface to accept
4102 new `type' argument to indicate the type of the message sent
4103 by the library. The application may filter the library's
4104 messages according the type. The affected file is the
4105 lib/silcclient/silcapi.h.
4107 * Added two new functions to lib/silcclient/silcapi.h:
4108 silc_client_del_client and silc_client_del_client_by_id.
4109 Affected file lib/silcclient/idlist.c.
4111 * Moved the clientincludes.h from includes/ to silc/ and
4112 serverincludes.h from includes/ to silcd/.
4114 * The modes for the CMODE and CUMODE are now passed as
4115 uint32 for application with COMMAND_REPLY. The affected
4116 file is lib/silcclient/command_reply.c.
4118 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4120 * /WHOIS without arguments shows client's own information.
4121 Affected file lib/silcclient/command.c.
4123 * Changed PING to not accept any arguments. The specs
4124 says that client can ping only the connected server so
4125 requiring an argument is not needed. Affected file is
4126 lib/silcclient/command.c.
4128 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4130 * Fixed a fatal bug in private message sending and reception
4131 encryption and decryption when using private message keys.
4132 The implementation was incorrect and did not follow the
4133 specification. It causd that some of the message were
4134 lost since it did not use the sending and receiving keys
4135 as the protocol suggests. This has been fixed and will cause
4136 incompatibilities with older clients when sending private
4137 message encrypted with private message keys. Affected files
4138 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
4139 and various other in Irssi SILC Client.
4141 Added `responder' boolean argument to the functions
4142 silc_client_add_private_message_key[_ske] to indicate when
4143 the key is added as responder or initiator of the key
4146 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4148 * Removed the silc_ske_check_version function and created
4149 a SilcSKECheckVersion callback. Added also a function
4150 silc_ske_set_callbacks that is now used to set all SKE
4151 callbacks. The callback functions are not given to
4152 the SKE functions anymore, but this function is used to
4155 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
4157 * Added `silc_version' argument to the silc_client_alloc
4158 to define the version of the application for the library.
4159 The library will use the version string to compare it
4160 against the remote host's (usually a server) version
4161 string. Affected file lib/silcclient/silcapi.h
4163 * Added the KE protocol context to Key Agreement context
4164 in client library so that we can abort the SKE if it
4165 is in process when we get timeout. Affected file is
4166 lib/silcclient/client_keyagr.c.
4168 * Do not resolve the client ID forever if it returns in the
4169 first time that such client does not exist. This was done
4170 for example with private message. Affected file is
4171 lib/silcclient/client_prvmsg.c.
4173 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4175 * Do not add regex.h for WIN32. The affected file
4176 includes/silcincludes.h.
4178 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
4179 not work yet 100%. It generates the DLL's automatically
4180 when compiling with --with-win32 under cygwin.
4182 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4184 * lib/contrib/regex.c is not compiled on WIN32.
4186 * Added silc_net_get_socket_opt function to the
4187 lib/silcutil/silcnet.h.
4189 * Added includes/silcwin32.h for WIN32 specific includes
4192 * Do not use ptime structure or any of the posix process
4193 functions on WIN32 in lib/silccrypt/silrng.c.
4195 * Added silc_gettimeofday to provide generic function
4196 for struct timeval on all platforms. Added the function
4197 to lib/silcutil/silcutil.h.
4199 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4201 * Moved the lib/silccore/silcsockconn.[ch] to the utility
4202 library as they clearly belong there. As a plus side we
4203 can make the actual socket connection routines platform
4206 Added also new generic function silc_socket_read and
4207 silc_socket_write (that used to be silc_packet_[read/write].
4208 The implementation of these are platform specific.
4210 * Added WIN32 specific routines of silc_socket_[read/write]
4211 to lib/silcutil/win32/silcwin32sockconn.c.
4213 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4215 * Added preliminary support for native WIN32 compilation under
4216 cygwin (using the -mno-cygwin option for GCC) to the
4217 ./configure.in.pre. The --with-win32 now prepares the
4218 compilation for native WIN32.
4220 * Rewrote the SILC Scheduler interface in the file
4221 lib/silcutil/silcschedule.h. The scheduler is now context
4222 based and does not have anymore any global static scheduler.
4223 Moved the Unix scheduler to the lib/silcutil/unix/ directory
4224 and created lib/silcutil/win32 directory for WIN32 based
4227 * Added Unix specific network routines to the
4228 lib/silcutil/unix/silcunixnet.c and the old
4229 lib/silcutil/silcnet.c includes now only generic routines.
4231 Added WIN32 specific network routines to the
4232 lib/silcutil/win32/silcwin32net.c.
4234 * Added Unix specific utility functions from the
4235 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
4237 * Added WIN32 SILC Scheduler to the file
4238 lib/silcutil/win32/silcwin32schedule.c. The code is of course
4241 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4243 * Do not handle JOIN notify in the server if the target client
4244 is not registered (idata->registered == FALSE). The affected
4245 file is silcd/packet_receive.c.
4247 * Update the nickrec->founder in event_cumode in the Irssi SILC
4248 client. Affected file irssi/src/silc/core/silc-channels.c.
4250 * Fixed the CUMODE_CHANGE notify handling in the server when
4251 server and router are announcing their clients on channels.
4252 Now the mode changes are saved and notified correctly. The
4253 affected file is /silcd/packet_receive.c.
4255 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
4256 They really did not replace the cache entry in the ID Cache.
4257 Now they do that. Affected file silcd/idlist.c.
4259 * Fixed the KICK notify handling in the Irssi SILC client to
4260 update the channel records so that the kicked client does not
4261 appear to be on the channel. The affected file is
4262 irssi/src/silc/core/silc-channels.c.
4264 * Always update the conn->current_channel when executing command
4265 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
4267 * Fixed the KILL notify handling in Irssi SILC client to remove
4268 the killed client on all channels.
4270 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4272 * Fixed the silc_parse_command_line to remove extra spaces
4273 from the start and end of the arguments. Affected file is
4274 lib/silcutil/silcutil.c.
4276 * Cancel and free any active protocol in the function
4277 silc_server_close_connection. Affected file silcd/server.c.
4279 * Cancel and free any active protocol in the function
4280 silc_client_close_connction. Affected file is
4281 lib/silcclient/client.c.
4283 * Do not execute the KILL command for clients that are in
4284 history (ie. they are not in the network). Affected file is
4287 * Fixed KILL notify handling, client does not crash anymore.
4288 Affected file irssi/src/silc/core/silc-channels.c.
4290 * Reduced the default packet buffer size from 2048 to 1024 in
4291 lib/silccore/silcpacket.c.
4293 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
4294 counter to the SKE context that is incresed when the SKE library
4295 performs async operation outside the library. If the outside
4296 process frees the SKE context and FREED status will be set
4297 and the library will detect after the sync operation that the
4298 libary is freed. The affected files are
4299 lib/silcske/silcske[_status].[ch].
4301 * Resolve the client entry information in the function
4302 silc_client_channel_message to assure that NULL pointer is not
4303 passed as client entry to the application. */
4305 * Fixed the task timeout calculation to assure that there is
4306 never negative timeouts. The affected file is
4307 lib/silcutil/silcschedule.c.
4309 * Fixed the channel user mode notification sending in server.
4310 It was sent point-to-point to the router (or to server by router)
4311 but it needs to be destined to a channel. The routines now
4312 supports sending the channel user mode notifys to the channels
4313 when announcing clients and channels. Affected files are
4314 silcd/server.c and silcd/packet_receive.c.
4316 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
4317 It did not actually replace the old channel entry in the cache.
4318 Affected file lib/silcclient/client_notify.c.
4320 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4322 * Fixed a possible crash in silc_packet_send_prepare. It now
4323 assures always that there is enough space in the buffer and
4324 at the tail area of the buffer (for MAC).
4326 Fixed the inbound buffer reallocation in silc_packet_read.
4327 It was old code and did not handle the reallocation correctly.
4330 The affected file is lib/silccore/silcpacket.c.
4332 * Fixed buffer overflow in silc_parse_nickname in the file
4333 lib/silcutil/silcutil.c.
4335 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4337 * make install generates new server keys only if there is not
4340 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4342 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
4343 Added check that if the NOREPLY is set then we will not send
4344 the away message. This avoids infinite loop of away messages
4345 if both clients are away. The affected file is
4346 lib/silcclient/client_prvmsg.c.
4348 * Fixed client crash if /NICK was given without arguments.
4349 Affected file lib/silcclient/command.c.
4351 * Server does not send the invite list in INVITE command back
4352 to the client if the list was not altered. Added this notion
4353 to the protocol spec as well. Affected file silcd/command.c.
4355 Fixed possible crash in INVITE command by checking the
4356 value of silc_server_get_client_route command.
4358 * Fixed the INVITE notify type handling. The arguments are now
4359 taken in correct order and client does not crash. The affected
4360 file is irssi/src/silc/core/silc-channels.c.
4362 Removed the "Inviting xxx to channel" message from the
4363 client library away and let the application handle it.
4364 Affected file lib/silcclient/command.c. Added that message
4365 to Irssi SILC client's message formats.
4367 * Fixed CMODE command crash in client. It now checks the
4368 amount of arguments correctly and does not crash. The affected
4369 file is lib/silcclient/command.c.
4371 * Do not create new channel automatically in silc_channels_join
4372 but check whether the channel by that name already exists.
4373 Affected file irssi/silc/core/silc-channels.c.
4375 * Do not send the SERVER_SIGNOFF to router if the disconnected
4376 entity was the router. Affected file silcd/server.c.
4378 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
4379 SILC client as it was missing from there.
4381 Added the handling of the KICK notify to the Irssi SILC client
4382 as it was missing. Added "you have been kicked" message to
4383 Irssi SILC client's message modules formats.
4385 Added the handing of the KILL notify to the Irssi SILC client
4386 as it was missing. Added the kill message module formats
4389 The affected file is irssi/src/silc/core/silc-channels.c.
4391 * The router did not save the channel mode the server announced.
4392 Affected file silcd/packet_receive.c.
4394 * Fixed a possible crash in INFO command in server. If the
4395 server did not provide the server info it crashed. Affected
4396 file silcd/command.c.
4398 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4400 * Fixed the GETKEY command in the server to check also the
4401 global list. Otherwise the GETKEY would not work correctly
4402 in normal SILC server. Affected file silcd/command.c.
4404 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4406 * Fixed GETKEY crash, it crashed if the command did not succseed.
4408 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4410 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
4411 is now real and not just an macro interface to GMP.
4413 Removed the entire GMP from the source tree and imported new
4414 NSS MPI library instead. Reason for removing GMP is that it is
4415 extremely large and compiles extremely slow. The NSS MPI
4416 is only a few files and compiles in less than 10 seconds.
4417 The speed is also about the same as GMP. The MPI is imported
4418 to lib/silcmath/mpi.
4420 If the system has GMP installed we will still use the GMP.
4421 If it is not then the NSS MPI will be compiled.
4423 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4425 * Merged a long nickname (127 characters long) crash bugfix from
4426 Irssi CVS tree. Affected file irssi/src/core/misc.c.
4428 * Merged a freed memory reference bugfix from Irssi CVS tree.
4429 Affected file irssi/src/core/commands.c.
4431 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4433 * Added the server's public key sving and verification to the
4434 server when performing the SKE. This was missing and the
4435 remote server's (or router's) public key was accepted without
4436 checking whether we have it previously or trust it at all.
4437 Affected file silcd/protocol.c.
4439 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4441 * Check in the silc_server_timeout_remote if protocol is active
4442 and make sure that the protocol's final callback is called so
4443 that all memory if freed. Affected file silcd/server.c.
4445 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4447 * silc_server_whois_send_reply crashed the server if the nickname
4448 was 127 characters long. Affected file silcd/command.c.
4450 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4452 * Added sanity check to the silc_server_new_client. If the hostname
4453 is provided inside username then check that the provided hostname
4454 really is the same as the resolved one. If the hostname was not
4455 resolved then check it from the public key. Affected file is
4456 silcd/packet_receive.c.
4458 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
4459 if the server disconnected us and the connection is not valid
4460 anymore. Affected file irssi/src/silc/core/silc-channels.c.
4462 * Moved the silc_client_[chmode|chumode|chumode_char] away from
4463 the library to the lib/silcutil/silcutil.[ch].
4465 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4467 * Close log file after open. Affected file
4468 lib/silcutil/silclog.c.
4470 * Check whether sock == NULL in silc_client_send_packet and return
4471 if it is. Affected file lib/silcclient/silcclient.c.
4473 * Check rec->entry == NULL in the Irssi SILC Client before
4474 sending the channel message. Affecte file is
4475 irssi/src/silc/core/silc-servers.c.
4477 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4479 * Merged a splitted window bugfix from Irssi CVS tree. The
4480 affected file is irssi/src/fe-text/textbuffer-view.c.
4482 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
4483 It did not print nickname.
4485 * Improved the distributions system a bit.
4487 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4489 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
4490 irssi/src/fe-text/gui-window.c.
4492 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
4493 to in-active server. The affected file is
4494 irssi/src/silc/core/client_ops.c.
4496 * Resolve the client in USERS command reply if the entry does
4497 not have username resolved. The affected file is
4498 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
4499 command to WHOIS command to really resolve stuff. The USERS
4500 is not used any more in any critical section so WHOIS can
4501 be used even though it might be slower than IDENTIFY.
4503 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
4506 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4508 * Changed the protocol API a bit more consistent in the
4509 lib/silccore/silcprotocol.[ch].
4511 * Changed the following headers to ROBODoc format:
4513 lib/silccore/silcpayload.h
4514 lib/silccore/silcprotocol.h
4515 lib/silccore/silcsockconn.h
4517 All core library headers are now formatted.
4519 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4521 * Fixed a bug in Irssi SILC client; do not show that you are
4522 server/router operator if you really are not. Affected file is
4523 irssi/src/silc/core/client_ops.c.
4525 * Renamed silc_command_free_payload to silc_command_payload_free.
4526 Affected file lib/silccore/silccommand.h
4528 * Added silcmath.h to include the prototoypes of various routines
4529 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
4532 * Changed the following headers to ROBODoc format:
4534 lib/silccore/silcchannel.h
4535 lib/silccore/silccommand.h
4536 lib/silccore/silcid.h
4537 lib/silccore/silcidcache.h
4538 lib/silccore/silcmode.h
4539 lib/silccore/silcnotify.h
4540 lib/silccore/silcpacket.h
4541 lib/silcmath/silcmath.h
4543 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4545 * Added checking to the server code not to start the server if
4546 ciphers and stuff are not configured properly. Affected files
4547 silcd/serverconfig.[h] and silcd/server.c.
4549 * Changed the layout of the header files of the public interfaces
4550 in the SILC libraries. The new layout supports ROBODoc
4551 documentation tool (and some others) so that it is easy to create
4552 a library reference manual. All the other headers and source
4553 code must still follow the CodingStyle document. Also source
4554 code must not include these ROBODoc stuffs, only the headers.
4555 Furthermore, all public interface headers must now be named
4556 by using `silc' prefix, example: silcapi.h, silccipher.h.
4557 Some files were renamed due to this. All the other headers
4558 must not be used as public interfaces. I will update the
4559 CodingStyle document later. Changed following headers, so far:
4561 lib/silcclient/silcapi.h
4562 lib/silccore/silcauth.h
4563 lib/silccore/silcprivate.h
4564 lib/silccrypt/silcdh.h
4566 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4570 * Removed silc_client_packet_send_flush from the client library
4571 as it is not needed. Affected file lib/silcclient/client.[ch].
4573 * Added printing of message of unresolved authentication method
4574 to the Irssi SILC client. Added it to the module formats.
4575 Removed the same message from the client library.
4577 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4579 * Added new distribution feature, DISTLABEL. Every distribution
4580 can define own preprocessor label that can be used in the
4581 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
4582 file distributions, acconfig.h.pre and prepare.
4584 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4586 * Added Makefile.defines_int to include the actual definitions
4587 for Makefile.defines.in. Tested the new distribution system,
4588 created distributions and tested installation.
4590 * Added AWAY message printing to the Irssi SILC client. Added
4591 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
4593 * Added SCONNECT command to call the SILC's CONNECT command.
4594 Cannot use CONNECT directly since Irssi uses that internally.
4595 Affected file irssi/src/silc/core/silc-servers.c.
4597 Added ACTION local command. It is same as ME command but takes
4598 the channel as mandatory argument.
4600 Rewrote some of the Irssi's help files to suite for SILC
4603 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4605 * Added Makefile.defines[.in] that should for now on be included
4606 in all Makefile.am file in the source tree. That file includes
4607 all common compilation definitions for SILC source tree.
4609 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4611 * Minor changes to the ./prepare script to change the package
4612 name according the distribution name to the configure.in.
4614 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4616 * Created new distribution system. Added file `distributions'
4617 that defines all the distributions that can be created out of
4618 the SILC source tree. The ./prepare script now reads that
4619 file to determine how to prepare the distributions. The
4620 first argument to the ./prepare is the name of the distribution
4621 and second is the version of the distribution. If given
4622 without arguments it creates the default (toolkit) distribution
4623 with the default version (defined in ./prepare).
4625 All Makefile.am files that are subject to the distributions
4626 are now named as Makefile.am.pre. These are ./Makefile.am
4627 and lib/Makefile.am. Others may be changed later.
4629 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4631 * Added invite list, ban list, some key management and connection
4632 error message printing to module formats in the Irssi SILC client.
4634 * Added new silc_client_set_away_message to set the away message
4635 that is back to the person who sent private message. The
4636 affected file lib/silcclient/silcapi.h and the
4637 lib/silcclient/client_prvmsg.c.
4639 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4641 * Fixed the private message sending in the Irssi SILC client,
4642 added local command KEY to the Irssi SILC client.
4644 Added key management and key agreement message formats to the
4645 irssi/src/fe-common/silc/module-formats.[ch].
4647 Added USERS (alias WHO) printing, server/router operator
4648 indication and LIST command printing to the module formats.
4650 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4652 * Fixed channel joining notify handling, cumode notify handling
4653 from Irssi SILC client.
4655 * Added SILC specific module-formats to the Irssi SILC client so
4656 that SILC specific message hilighting, colors etc is possible.
4657 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4659 Added channel mode, channel user mode, actions, notices,
4660 whois and whowas printing to the the module-formats.c.
4662 * Fixed a bug in channel deletion in the server. The channel
4663 is not left to the cache even if the channel founder auth mode
4664 is set when there are no users anymore on the channel. Affected
4665 file silcd/server.c.
4667 * The silc_net_localhost now resolves the entire hostname including
4668 the domain name. Affected file lib/silcutil/silcnet.c.
4670 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4672 * Changed the ask_passphrase client operation to be ascynchronous.
4673 It has now a completion callback and a context that the
4674 application must call after it has got the passphrase from
4675 the user. Affected files lib/silcclient/silcapi.h,
4676 lib/silcclient/protocol.c, lib/silcclient/command.c and
4679 Added SilcAskPassphrase callback that the application calls
4680 to deliver the passphrase to the library.
4682 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4683 The public key verification and especially a certificate
4684 verification is asynchronous procedure.
4686 Added new SILC_SKE_STATUS_PENDING status to indicate the
4687 request is pending and a callback will be called to finalize
4690 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4691 indicate that remote end did not send its public key (or
4692 certificate), even though we require it. Added check for this
4693 condition in the SKE. This was a security bug, now fixed.
4695 Defined new SilcSKEVerifyCbCompletion callback that is called
4696 when the verification process is completed.
4698 The affected files lib/silcske/silcske_status.h and
4699 lib/silcske/silcske.[ch].
4701 * Changed the verify_public_key client operation to be async
4702 as well. Defined SilcVerifyPublicKey callback that is used to
4703 indicate the success of the public key verification process.
4705 Changed the server and client to use the new async client
4708 * Changed the Irssi SILC client's internal scheduler to be called
4709 twice as many times as it used to be. As a result the client
4710 should be a bit faster now. Affected file is
4711 irssi/src/silc/core/silc-core.c.
4713 * Added support to Irssi SILC client of asynchronous public key
4714 verification and passphrase inquiry. Affected file is
4715 irssi/src/silc/core/silc-core.c.
4717 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4719 * Do not say "You have left channel %s" in client library.
4720 Moved it to the application. Affected files are
4721 lib/silcclient/command.c and silc/client_ops.c.
4723 * Fixed silc_client_get_clients. Command context was not
4724 duplicated and was freed memory in the callback. Affected
4725 file lib/silcclient/idlist.c.
4727 * Do not say "you are now talking..." on JOIN command in the
4728 client library. The appliation must handle it.
4730 * Do not say ".. changed topic to" in command reply in the
4731 client libary. The application must handle it.
4733 * Fixed TOPIC command sending in the client library.
4735 * Fixed a memory leak in silc_client_command_free in the file
4736 lib/silcclient/command.c.
4738 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4740 * Imported a modified version of Irssi client to the source tree.
4741 The Irssi will be used to create a new client called
4742 Irssi SILC. Imported to irssi/.
4744 Added silc_core_init_finish function to the Irssi. Affected
4745 file irssi/configure.in.
4747 A lot changes in the Makefile.ams around the irssi tree.
4749 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4751 * Do not rehash if the new size is same as the old size of the
4752 hash table, in the silc_hash_table_rehash*. The affected file
4753 lib/silcutil/silchashtable.c.
4755 * Replaced hash_table_del_by_context calls from the server
4756 (when channel->user_list and client->channels) to the
4757 hash_table_del as it is sufficient and faster.
4759 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4761 * Added silc_hash_table_list, silc_hash_table_get and the
4762 SilcHashTableList structure to provide an alternative way to
4763 traverse the hash table. The affected files are
4764 lib/silcutil/silchashtable.[ch].
4766 * Changed the server's idlist routines to use the hash table
4767 routines to optimize the code.
4769 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4771 * Replaced the client entry's `channel' list and channel entry's
4772 `user_list' list to hash tables for optimized lookup. Changed
4773 the code to use the hash table interface around the code.
4774 Affected file lib/silcd/idlist.[ch].
4776 * Added `auto_rehash' boolean argument to the function
4777 silc_hash_table_alloc to indicate whether the hash table should
4778 auto-rehash when it thinks is appropriate time. It will
4779 increase the hash table size if the there is twice as much
4780 entries in the table than the size of the table, and will
4781 decrease the size if there are twice as less entries than
4782 the size of the table.
4784 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4786 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4788 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4790 * silc_idcache_purge_by_context deletes the entry now by context
4791 as it is supposed to do. Affected file lib/silccore/idcache.c.
4793 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4794 client is not anymore valid (WHOWAS givens the info) and not
4795 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4797 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4799 * Removed the `data' and `data_len' arguments from the ID Cache
4800 interfaces and added `name' argument. ID Cache does not handle
4801 anymore the binary data only a names associated with given ID.
4803 * When hashing a Client ID with silc_hash_id the entire ID is
4804 not hashed anymore, instead only the hash of the Client ID is
4805 hashed. This way we can access the Client ID from the cache
4806 with Client ID but with the hash of the ID (which is a hash of
4807 the nickname) as well without any difference in performance.
4809 Added also silc_idcache_find_by_id_one_ext to do one on one
4810 searching when we have the actual ID. Added also function
4811 silc_hash_client_id_compare. The affected files are
4812 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4814 * When hashing the name associated with a ID it is always done
4815 in lowercase. This way we can access the cache without worrying
4816 about case-sensitivity, even though, for example nicknames are
4819 * Fixed a bug in server with channel message sending. It put
4820 wrong ID type as destination ID. The affected file
4821 silcd/packet_send.c.
4823 * silc_idcache_del_by_context now deletes from all hash tables
4824 by context. Affected file lib/silccore/idcache.c.
4826 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4828 * Changed the client library to use the new ID Cache interface.
4829 Changes around the source tree.
4831 * Added silc_hash_table_rehash_ext to rehash with specific
4832 hash function. Affected file lib/silcutil/silchashtable.[ch].
4834 * Added silc_hash_string_compare to compare two strings in the
4835 hash table. Affected file lib/silcutil/silcutil.[ch].
4837 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4839 * Added new function silc_idcache_del_by_context into the
4840 lib/silccore/idcache.[ch].
4842 * Changed the server's ID list routines to use the new ID Cache
4843 interface. Changes around the source tree.
4845 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4847 * Added silc_hash_table_del[_by_context]_ext functions in to the
4848 lib/silcutil/silchashtable.[ch].
4850 Removed silc_hash_table_find_all* routines and added new
4851 silc_hash_table_find_foreach to replace them.
4853 Added silc_hash_table_replace_ext function as extended
4854 replacing function. Separated the simple hash table interface
4855 from the extended hash table interface in the file
4856 lib/silcutil/silchashtable.h.
4858 * Fixed minor bugs and changed it to use some of the new
4859 hash table functions in lib/silccore/idcache.c
4861 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4863 * Added new function silc_hash_table_find_all to return all keys
4864 in the hash table by the specified key. As the hash table is
4865 collision resistant it also makes it possible to have several
4866 duplicate keys in the hash table. This function may be used to
4867 find all of the keys from the hash.
4869 Added user_context arguments to the SilcHashFunction,
4870 SilcHashCompare and SilcHashDestructor to deliver user specified
4873 Added new fuctions silc_hash_table_find[_all]_ext to do
4874 extended lookup with specified hash and compare functions and
4875 specified user contexts.
4877 Added new function silc_hash_table_add_ext to add the key
4878 with specified hash function and user context.
4880 Added new function silc_hash_table_foreach to traverse all
4881 entrys in the hash table. Added SilcHashForeach callback
4884 Added new function silc_hash_table_del_by_context to delete
4885 the entry only if the context associated with the key matches.
4887 Affected files are lib/silcutil/silchashtable.[ch].
4889 * Removed silc_hash_[server/client/channel]_id and added just
4890 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4891 silc_hash_id_compare to compare two ID's using as the hash table
4892 comparison function. Added also silc_hash_data to hash
4893 binary data and silc_hash_data_compare to compare it.
4895 * Removed silc_idlist_find_client_by_hash as it is not needed
4896 anymore. Affected file silcd/idlist.[ch].
4898 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4899 to use internally the SilcHashTable. The new ID Cache is a lot
4900 faster than the old one. Some of the ID Cache interface was also
4901 rewritten and obsolete and stupid functions were removed.
4903 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4905 * Added entry_count field to the SilcHashTable to keep the number
4906 of the entries in the table. Implemented the function
4907 silc_hash_table_rehash. Added new function
4908 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4910 Fixed a minor bug in silc_hash_table_free.
4912 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4913 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4914 into the lib/silcutil/silcutil.[ch].
4916 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4918 * Implemented a collision resistant hash table into the
4919 lib/silcutil/silchashtable[ch]. See the header and the source
4920 for the SilcHashTable API.
4922 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4924 * Merged dotconf version 1.0.2 into lib/dotconf.
4926 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4928 * Do not compile anything in lib/silcsim/* if the SIM support
4929 is not enabled. The tree should now compile without problems
4932 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4934 * Compiled the SILC under cygwin. Compiled and tested briefly
4935 without problems. More tests needed. The SIMs didn't compile
4938 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4940 * Fixed possible crash in silc_get_username in the
4941 lib/silcutil/silcutil.c.
4943 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4945 * Fixed a va_arg in silc/client_ops.c.
4947 * Oops, RC5 routines were named AES and caused some problems
4948 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4950 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4952 * Added new SilcIDIP structure into the lib/silccore/id.h and
4953 replaced the old `ip' fields from all SILC ID's to that type.
4954 This is a step towards IPv6 support.
4956 The silc_id_get_len takes now the ID as an extra argument.
4957 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4958 both IPv4 and IPv6 based ID's.
4960 The affected files are lib/silccore/id.[ch] and other files
4961 around the tree using these routines.
4963 * Removed the ID length arguments in server from various
4964 silc_server_send_notify_* routines -> they are not needed
4967 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4969 * Fixed memory leak in silc_encode_pem_file in the file
4970 lib/silcutil/silcutil.c.
4972 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4974 * Check minor version as well in the SKE. Affected files are
4975 silcd/protocol.c and lib/silcclient/protocol.c.
4977 * Added --identifier option to the server so that an identifier
4978 can be when creating the public key for the server. Affected
4979 file is silcd/silcd.c.
4981 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4982 lib/silccrypt/silcpkcs.c.
4984 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4986 * Register default ciphers and stuff when using -C option with
4987 the server. Affected file sildc/silcd.c.
4989 * Put back the servers public key filename format, it is better
4990 than the new one. For now, the client keys are saved with the
4991 new filename format. The affected file silc/client_ops.c.
4993 * Implemented the Cipher API for the rest of the ciphers that
4994 did not implement it or implemented it the wrong way.
4996 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4998 * Register default ciphers and stuff when using the -S option
4999 in the client. Affected file silc/silc.c. Same also when
5000 creating new key pair with -C option.
5002 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5004 * Fixed the silc_verify_public_key client operation function to
5005 save the public keys differently. The fingerprint is now
5006 used as filename and not the hostname. This way also the
5007 client keys are saved uniquely and not with hostnames. The
5008 affected file is silc/client_ops.c.
5010 * Trimmed the silc_hash_fingerprint function to remove extra
5011 whitespaces from the end of the fingerprint. The affected
5012 file is lib/silccrypt/silchash.c.
5016 * Added silc_cipher_register_default function to register all
5017 default ciphers. It can be used when configuration files
5018 does not exist and the application does not want any specific
5019 ciphers in any specific order.
5021 The SilcDList is now used as silc_cipher_list dynamically
5022 allocated cipher list. Removed the static list all together
5023 and now all ciphers must be allocated to the dynamic list.
5024 The silc_cipher_alloc routine was changed to check only the
5027 All silc_cipher_* routines that used to return int returns
5030 The affected files lib/silccrypt/silccrypt.[ch].
5032 * The same thing was done to silc_hash_* as for silc_cipher_*
5033 routines. Affected files lib/silccrypt/silchash.[ch].
5035 * The same thing was done to silc_pkcs_* as for silc_cipher_*
5036 routines. Affected files lib/silccrypt/silcpkcs.[ch].
5037 Added also silc_pkcs_[un]register[_default] functions.
5038 Removed the data_context from the PKCS API.
5040 * Added silc_hmac_register_default function to register default
5041 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
5042 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
5043 to unregister all hmacs at once.
5045 * Register the default ciphers, hash functions, PKCSs and HMACs
5046 if client's configuration file does not exist. The affected
5049 * The client did not load the hash functions from the SIM
5050 modules at all. Added support for this. Affected file is
5051 silc/clientconfig.c.
5053 * When decoding public key with silc_pkcs_public_key_decode, check
5054 the supported algorithm only if PKCS are registered. Affected
5055 file lib/silccrypt/silcpkcs.c. The same was done with the
5056 silc_pkcs_private_key_decode.
5058 * Fixed the SILC List routines to keep the list always in order.
5059 It used to change the list's order when traversing the list but
5060 not it preserves the order. Affected file lib/trq/silclist.h.
5062 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5064 * Added the client library to use the SilcSocketConnection's
5065 reference counter (by silc_socket_dup) to prevent the bug that
5066 the socket object may be freed underneath async operation.
5068 * The name resolv library checking fixes in the configure.in.pre.
5071 * Created new version of the protocol drafts for future
5072 development. The -03 drafts are the ones that will be changed
5073 in the trunk now and the -02 will remain as they are.
5075 * Send list of CUMODE notifys to the router when announcing
5076 the channel users to the router. Affected file silcd/server.c.
5077 If the router receiving channel founder CUMODE for a channel
5078 that already has channel founder it will send CUMODE notify
5079 to the sender to remove the channel founder rights from the
5080 announced client. Affected file silcd/packet_receive.c.
5082 * The CUMODE notify may now use Server ID as well as the entity
5083 who changes the mode. Updated protocool specs.
5085 * Updated INSTALL and README files.
5087 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5089 * New web pages in the http://silc.pspt.fi. The pages was
5094 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5096 * Implemented the [DenyConnectin] config section in the server.
5097 Added silc_server_config_denied_conn to check whether incoming
5098 connection is denied. Affected file silcd/serverconfig.[ch].
5100 * Do not check the ports when checking the incoming configuration
5101 data if the port is 0, meaning any. Affected file is
5102 silcd/serverconfig.c.
5104 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5106 * Fixed buffer overflow in silc_string_compare in the file
5107 lib/silcutil/silcutil.c.
5109 * Fixed double free in silc_server_command_leave in the file
5112 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5114 * Fixed the version checking in the server. Affected file is
5117 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5119 * Fixed the configuration data fetching when accepting new
5120 connections in the server. Affected file silcd/server.c.
5122 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5124 * Added `sender_entry' argument to the function
5125 silc_server_packet_relay_to_channel so that we can check
5126 whether some destination actually belongs to the same route
5127 the sender belongs (ie, we must not resend the packet to the
5128 sender). Affected file silcd/packet_send.[ch].
5130 * Added `servername' field to the SilcClientEntry in the server
5131 to hold the name of the server where client is from. Affected
5132 file is silcd/idlist.h.
5134 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5136 * Moved the channel message encrypting in the router betwen
5137 router connections from silc_server_channel_message to the
5138 silc_server_packet_relay_to_channel since we want to check
5139 whether we have anybody channel before encrypting anything.
5140 Affected files silcd/packet_[receive/send].c.
5142 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5144 * Fixed the [AdminConnection] server config section to support
5145 multiple entries. Affected file silcd/serverconfig.c.
5147 * Added support into the server to check the validity of the
5148 incoming connection before executing any KE or authentication
5151 * The connection configuration is now saved to the KE and
5152 connection auth protocol contexts and not fetched anymore in
5153 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
5155 * The local hosts listenning address and port is also resolved
5156 now when starting the server. We want to have the socket object
5157 to include the real address and port for the listener. Added
5158 new function silc_net_check_local_by_sock into the files
5159 lib/silcutil/silcnet.[ch].
5161 * Fixed a broadcast bug in server -> do not broadcast if we
5164 * Fixed a routing bug. Do not route broadcast packets ever.
5165 Broadcast packets must be processed always and not routed since
5166 they may be destined to some other host than yourself and thus
5167 would get routed without no good reason. Affected file is
5170 * Added function silc_server_config_is_primary_route to check
5171 whether primary router connection has been configured (a router
5172 configuration that we are initiating). If there is not, we
5173 will assume that there is only two routers in the SILC network
5174 and we will use the incoming router connection as our primary
5175 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
5177 * Changed the order of the broadcasting. Broadcast _after_ the
5178 packet has been processed not before. Affected file is
5181 * Fixed a [ClientConnection] parsing bug. The port was never
5182 parsed correctly thus resulting to port 0. Affected file
5183 silcd/serverconfig.c.
5185 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
5186 argument and did not set the broadcast packet flag. Affected
5187 file silcd/packet_send.c. Fixed same bug in the function
5188 silc_server_send_notify as well.
5190 * If we receive NEW_ID packet for our own ID in the server, ignore
5193 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5197 * Removed the nickname from the Private Message Payload.
5198 Updated the code and the protocol specs.
5200 * Updated protocol specs for submitting to the IETF.
5202 * Tweaked the Random Number Generator a bit. Affected file
5203 lib/silccrypt/silcrng.c. Exported a new function
5204 silc_rng_[global]_add_noise which can be used to add more
5207 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5209 * Do not parse packets with different timeout when protocol
5210 is active -> may cause problem with rekey. Affected file
5213 * When server receives signoff notify it must not create
5214 new channel key if the client is on any channels since the
5215 sender of the signoff notify will create it.
5217 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5219 * Added printing of error messages during SKE protocol from the
5220 failure packet sent by server during SKE. Affected file
5223 * Removed the client's failure_callback handling with timeout
5224 and handle it immediately when received.
5226 * The SKE library returned wrong type in SUCCESS and FAILURE
5227 packets. They must be 32 bit MSB not 16 bit MSB.
5229 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5231 * Ok, rewrote the logic of the re-key and now it seems to work.
5232 I tested it on high traffic with frequent re-keys without
5233 problems. Added hmac_receive (and renamed hmac to hmac_send)
5234 in SilcClientConnection in lib/silcclient/client.h and
5235 in SilcIDListData in silcd/idlist.h. Also, removed the
5236 SilcPacketParserContext's cipher and hmac fields as they are
5237 not needed anymore and actually caused some problems when
5238 the ciphers and hmac's changed underneath the packet parser.
5240 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5242 * If re-key protocol is active then process the incoming packets
5243 synchronously since we must assure that icoming packets encrypted
5244 with the old key is processed before the new keys is set to
5245 use. This is true other packets than for REKEY packets.
5246 Affected file silcd/server.c. The same was done to client library
5247 as well, affected file lib/silcclient/client.c.
5249 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5251 * Fixed bug in client and server to accept the force send if
5252 the packet is send from silc_[server/client]_packet_process
5253 function. Otherwise the packets are never delivered, oops.
5255 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5257 * Disable force sending of packets when REKEY protocol is active.
5258 We must assure that no packet is sent directly when rekey is
5259 performed. All packets must be sent through packet queue.
5260 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
5261 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
5262 function is silc_[server/client]_packet_send_real to check
5265 * Replaced the SIM paths from example config files to
5266 /usr/local/modules. Also, make install creates now
5267 /usr/local/silc/logs directory to hold all the SILC server
5270 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5272 * Made the configure.in.pre work on Solaris. Patch by salo.
5274 * Made all ciphers compatible with non-x86 machines. Defined
5275 CBC mode macros into lib/silccrypt/ciphers_def.h.
5277 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5279 * Fixed the make install.
5281 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5283 * When MAC computation fails the silc_packet_decrypt returned 0
5284 even though it was supposed to return -1. Fixed this. The
5285 affected file is lib/silccore/silcpacket.c.
5287 * Do not replace the config files in /etc/silc (in make install)
5288 if they already exist. Affected file ./Makefile.am.
5290 * Do not send re-key packets immediately but through packet queue.
5291 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
5293 * Changed silc_net_check_host_by_sock to return FALSE if the
5294 IP/DNS could not be resolved. Though, it returns the IP address
5295 now even if it could not resolve it (but returns also FALSE).
5296 Affected file lib/silcutil/silcnet.[ch].
5298 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5300 * Added silc_pkcs_decode_identifier to decode the public key's
5301 identifier. Affected file lib/silccrypt/silpkcs.[ch].
5302 Added also silc_pkcs_free_identifier. Added also new context
5303 SilcPublicKeyIdentifier.
5305 * Added -S option to the silc client. It is used to dump the
5306 contents of the specified public key file.
5308 * Changed the PKCS api to return the public key length when
5309 setting the public key.
5311 * Fixed a fatal bug in the public and private key file loading.
5312 Affected file lib/silccrypt/silcpkcs.c.
5314 * Execute the packet parsing for client with zero (0) timeout
5315 if the protocol is active. Affected file silcd/server.c.
5317 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5319 * Made the key generation options to the silcd program. Added
5320 -C option, equivalent to client's option.
5322 * Added new [ServerKeys] config section to the server. It
5323 configures the server's public and private key.
5325 * Defined generic Public Key Payload into the protocol
5326 specification to send specific type of public keys and
5329 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
5330 public key or certificate.
5332 * Implemented the GETKEY command to the server and to the
5333 client library and on user interface.
5335 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5337 * Made preliminary `make install' work.
5339 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5341 * Added SilcServerRekey context into silcd/idlist.h.
5343 * Added the PFS support as defined in the specification to the
5344 SKE protocol. Affected files lib/silcske/*.c.
5346 * Added `ske_group' field to the SilcServerRekey context to hold
5347 the number of the SKE group that is used with PFS in re-key.
5348 Affected file silcd/idlist.h.
5350 * Added PFS re-key support to the server. Affected file is
5353 * Added silc_protocol_cancel to cancel execution of the next
5354 state of the protocol. Affected file is
5355 lib/silccore/silcprotocol.[ch].
5357 * Added the re-key support with and without PFS to the client
5358 library. Re-key is performed once in an hour, by default.
5360 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
5361 Added silc_client_rekey_callback and silc_client_rekey_final.
5362 Affected files are lib/silcclient/protocol.[ch] and
5363 lib/silcclient/client.[ch].
5365 * Removed the `hmac_key' and `hmac_key_len' fields from the
5366 SilcClientConnection structure; not needed. Affected file is
5367 lib/silcclient/client.h.
5371 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5373 * Do not ask whether user wants to use the negotiated private key
5374 for private messages, just use it. Affected file is
5375 silc/local_command.c.
5377 * Added `send_enc_key' and `enc_key_len' fields to the
5378 SilcIDListData structure since they are needed in the re-key
5379 phase. Affected file is silcd/idlist.[ch].
5381 * Implemented the simple re-key protocol into the server.
5382 Affected files silcd/server.c and silcd/protocol.[ch]. The
5383 re-key will be performed once in an hour, by default.
5385 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
5386 Added silc_server_rekey, silc_server_rekey_callback and
5387 silc_server_rekey_final.
5389 * Removed Tunneled flag from the protocol. Updated the code
5390 and the specifications.
5392 * Adde `pfs' field to the SilcIDListData to indicate whether
5393 the PFS is to be performed in the re-key. Affected file is
5396 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5398 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
5399 int64 of at least the xintXX size. If void * is less that 4
5400 bytes uint32 * will be used. Defined bool as boolean.
5402 * Changed _ALL_ unsigned long and unsigned int to uint32,
5403 unsgined short to uint16 in the source tree.
5405 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
5406 not handle clients that has entry->data.registered == FALSE.
5407 They are not in the network anymore. Affected file is
5410 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5412 * Implemented the sending of the SERVER_SIGNOFF notify in the
5413 server. Affected file is silcd/server.c.
5415 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
5416 Added also silc_notify_payload_encode_args into the
5417 lib/silccore/silcnotify.[ch].
5419 * Implemented ther SERVER_SIGNOFF notify handling in the server.
5420 Affected file silcd/packet_receive.c.
5422 * Implemented the SERVER_SIGNOFF notify handling in the client
5423 library. Affected file lib/silcclient/client_notify.c. Also,
5424 implemnted the printing of the SERVER_SIGNOFF info to the
5425 application. Affected file silc/client_ops.c.
5427 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
5428 if the deleting was successful. Affected file silcd/idlist.[ch].
5430 * Added support for public key authentication in the connection
5431 authentication protocol in the client library. Affected file
5432 lib/silcclient/protocol.c.
5434 * Changed the server's silc_idlist_get_clients_by_* interface
5435 to support already allocated array so that new entries may be
5436 added to pre-allocated array. Affected file silcd/idlist.[ch].
5437 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
5438 and command replies.
5440 * All command reply functions in the server now calls the
5441 pending command callback even if error occured. This way the
5442 error will be delivered to the client as well. Affected files
5443 silcd/command.c and silcd/command_reply.c.
5445 * Fixed INFO command to return local server's info if no server
5446 was provided. Affected file lib/silcclient/command.c.
5448 * Removed RESTART command for good. Updated the code and the
5451 * Rewrote parts of the task system. It is a bit simpler now.
5452 Removed unsued task priorities. The affected files are
5453 lib/silcutil/silctask.[ch].
5455 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5457 * Moved the USERS printing from the library to the application.
5458 Affected files lib/silcclient/command.c and silc/client_ops.c.
5460 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5464 * Added channel key re-key support. The re-key is perfomed
5465 only by the router and is done once in an hour. Added `rekey'
5466 field to the SilcChannelEntry in the server. Affected files
5467 silcd/server.c and silcd/idlist.h.
5469 * Added silc_task_unregister_by_context into the file
5470 lib/silcutil/silctask.[ch].
5472 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5474 * Added SILC_UMODE_GONE mode to indicate when the client is not
5475 present in the SILC network. Added also support to the local
5476 command AWAY that will set this mode. Added support of showing
5477 "xxx is gone" in WHOIS command. The USERS command shows the
5478 gone status as well.
5480 * Fixed setting server and router operator privileges in the
5481 server's UMODE command. Affected file silcd/command.c.
5483 * Merged the SKE KE1 and KE2 payloads into one payload. The
5484 new KE payload is equivalent to the old KE2 payload.
5486 Cleaned up the SKE Start Payload parsing. It now uses the
5487 simple buffer unformatting to do the parsing. A lot faster
5490 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
5491 to the SKE that is used to indicate whether both of the SKE
5492 parties should perform authentication. By default only the
5493 responder performs authentication. By setting this flag also
5494 the initiator must do authentication. By default it is unset
5495 since in normal SKE case, client to server connection, only
5496 the responder should do authentication. When doing SKE between
5497 two clients both should perform authentication. Updated the
5498 code and the protocol specs.
5500 * A little fix to IDENTIFY command in the server. Search the
5501 client first by hash not nickname. Affected file is
5504 * Fixed the silc_client_close_connection to support closing
5505 the client to client connections wihtout deleting too much
5506 data. Affected file lib/silcclient/client.c.
5508 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
5509 are received if protocol used to be active but is not anymore
5510 the application would crash due to NULL pointer dereference.
5511 Affected files silcd/server.c and lib/silcclient/client.c.
5513 * Added `hash' field to the SilcClientConnection to include
5514 the hash function negotiated in the SKE protocol.
5516 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
5517 to set the channel founder authentication data. A client can
5518 claim the founder rights later by providing the authentication
5519 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
5520 This way the channel founder can regain the channel founder
5521 privileges even it is left the channel. This works only on
5522 local server and the client must be connected to the same
5523 server to be able to regain the founder rights. Updated the
5524 protocol specs accordingly.
5526 Added support to the CMODE command in the client to set the
5527 founder auth data. Read the README to see how to set it.
5529 Added support to the CUMODE command to claim the founder
5530 rights. Read the README to see how to do it.
5532 Added support for the founder authentication to the Channel
5533 Entry in the server. Affected file silcd/idlist.h.
5535 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
5536 server's CMODE command. Affected file silcd/command.c.
5538 * Added the following new functions into lib/silccore/silcauth.[ch]:
5539 silc_auth_get_method and silc_auth_get_data.
5541 * The server now saves the remote hosts public key to the
5542 SilcIDListData pointer. Affected file silcd/protocol.c.
5544 * The normal server now does not remove the channel entry from
5545 the cache if the founder authentication data is set. It used
5546 to remove it if the founder was the last one on the channel on
5547 the server and left the channel. The auth data is saved and
5548 if the channel is re-joined later the old entry is used with
5549 the old auth data. Affected files silcd/command_reply.c and
5552 * Removed the `pkcs' field from the SilcIDListData structure
5553 in the server; it is not used. Affected file silcd/idlist.h.
5555 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5557 * Fixed packet processing on slow links. Partial packets were
5558 never re-processed because the incoming data buffer was cleared
5559 by the application. Application must not directly clear the
5560 sock->inbuf, the packet processing routines handle it. Fixed
5561 this in client library and in server.
5563 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5565 * Fixed the WHOIS and IDENTIFY send reply function to really
5566 check whether to send list or just one entry. Affected file
5569 * Cleaned up the LEAVE command's channel key distribution. The
5570 affected file silcd/command.c.
5572 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
5573 can enforce the channel mode as well. In that case the ID
5574 includes the ID of the server. The code now enforces the
5575 mode change if the router have different mode than the server.
5577 * The notify client operation with CMODE_CHANGE notify can now
5578 return NULL client_entry pointer if the CMODE was not changed
5579 by client. Application must check for this.
5581 * Added <Server ID> argument to INFO command to support server
5582 info fetching by Server ID.
5584 * Added silc_server_announce_get_channel_users to get assembled
5585 packets of channel users of the specified channel. Affected
5586 file silcd/server.[ch].
5588 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
5589 was freed underneath the ID Cache.
5591 * Re-announce clients when the server received CHANNEL_CHANGE
5592 notify from the router. Affected file silcd/packet_send.c.
5594 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5596 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
5597 crashed since it did not handle the fact that there is no cipher
5598 called "3" and didn't check the error condition. Now fixed.
5600 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
5601 flag. It can be used to send message requests.
5603 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5605 * Implemented the RESTART command in the client.
5607 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
5608 notice type messages. Added notice printing to the user
5611 * The channel keys are not re-generated if the channel's mode
5612 is PRIVKEY, ie private key on the channel exists. Affected
5613 files silcd/server.c and silcd/command.c.
5615 * Fixed a little bug in channel message delivery when channel
5616 private keys are set in the server. Affected file is
5617 silcd/packet_send.c.
5619 * Changed the setting on channel->on_channel = TRUE from the
5620 silc_client_save_channel_key to the JOIN command reply. The
5621 key payload is not received if the private channel key is set.
5622 Affected file lib/silcclient/command_reply.c and the
5623 lib/silcclient/client_channel.c.
5625 * When the CMODE_CHANGE notify is sent and the channel private
5626 key mode is removed the channel key must be re-generated in
5627 other cells as well. Added this support for the router in the
5628 silcd/packet_receive.c.
5630 * Added new local command NOTICE to send notice message on
5631 channel. Affected file silc/local_command.[ch].
5633 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5635 * Added new local command ME to the client. It is used to send
5636 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
5637 some action. Affected file silc/local_command.[ch].
5639 * Changed channel_message and private_message client operations
5640 to deliver the message flags to the application. Added also
5641 the `flags' arguments to the silc_client_send_channel_message
5642 and silc_client_send_private_message functions. Affected file
5645 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5647 * Redefined the Private Message Payload to support private message
5648 keys and to support the new private message flags. Updated
5649 the protocol specs. Flags makes it possible to have for example
5650 CTCP style messages.
5652 * Added new type SilcPrivateMessagePayload and defined an API
5653 for it in the lib/silcclient/silcprivate.[ch].
5655 * Tested private message private keys successfully. Tested the
5656 private message key set, unset and list commands with the new
5659 * Redefined the Channel Message Payload to include the channel
5660 message flags (equal with private message flags) to support
5661 for example CTCP style messages.
5663 * Defined some of the message (for channel and private message)
5664 flags. Updated the protocol specs and added the flags to the
5665 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5667 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5669 * Added SilcKeyAgreementStatus type to the key agreement routines
5670 to indicate the current status and error if one occured.
5671 The status types are defined in the lib/silcclient/silcapi.h.
5673 * Added new local command KEY that is used to set and unset private
5674 keys for channels, set and unset private keys for private messages
5675 with remote clients and to send key agreement requests and
5676 negotiate the key agreement protocol with remote client. The
5677 key agreement is supported only to negotiate private message keys,
5678 it currently cannot be used to negotiate private keys for channels,
5679 as it is not convenient for that purpose.
5681 * Fixed a minor pending callback setting bug in the function
5682 silc_client_get_client_by_id_resolve, now the function works.
5683 Affected file lib/silcclient/idlist.c.
5685 * Added function silc_net_get_local_port to get local bound
5686 port by socket. Added to lib/silcutil/silcnet.[ch].
5688 * Added `sockets' and `sockets_count' fields to the SilcClient
5689 object. They hold the sockets of the listenning sockets in
5690 the client. Listenning sockets may be for example the key
5691 agreement server. Affected file lib/silcclient/client.[ch].
5692 Added functions the silc_client_add_socket and the
5693 silc_client_del_socket. They are exported to the application
5696 * Added ~./silc/clientkeys to support other client's public keys.
5698 * Renamed verify_server_key client operation to verify_public_key
5699 and added one argument to indicate the type of the connection
5700 (server, client etc.).
5702 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5704 * Added silc_server_connection_auth_request to handle the
5705 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5706 silcd/packet_receive.[ch].
5708 * Added silc_server_send_connection_auth_request into the
5709 silcd/packet_send.c to send the connection auth request packet.
5711 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5714 * Fixed the public key authentication in responder side in the
5715 server. The `auth_data' pointer includes the SilcPublicKey
5716 not the path to the public key. Affected file silcd/protocol.c.
5718 * Implemented the public key authentication in the initiator side
5719 in the server. Affected file silcd/protocol.c.
5721 * Removed the [RedirectClient] config section from the server
5722 configuration. Is not needed and I don't want to implement it.
5724 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5726 * Cleaned up the CMODE command in the server. It now works
5727 correctly and supports all the modes defined in the protocol.
5728 Affected file is silcd/command.c.
5730 * Added `hmac_name' field to the SilcChannelEntry in the server
5731 to hold the default HMAC of the channel. It can be set when
5732 creating the channel (with JOIN command). Affected files
5735 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5736 type to indicate the change of the current cipher and hmac
5737 on the channel. Client can safely ignore the <cipher> argument
5738 (if it chooses to do so) since the CHANNEL_KEY packet will
5739 force the channel key change anyway. The <hmac> argument is
5740 important since the client is responsible of setting the new
5741 HMAC and the hmac key into use.
5743 * Fixed the CMODE command in the client library as well.
5745 * Tested CMODE command in router environment successfully.
5747 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5749 * Show the version of the remote client (or server) when connecting
5750 to the server. It is logged to the log file. Affected file
5751 is silcd/protocol.c.
5753 * Fixed the KILLED notify handling in the client library. The
5754 client must be removed from all channels when receiving the
5757 Also, do not remove the client entry when giving the KILL
5758 command but when the KILLED notify is received.
5760 * Removed silc_idlist_find_client_by_nickname from the server.
5761 Not needed anymore. Affected files silcd/idlist.[ch].
5763 * Implemented the CHANNEL_CHANGE notify type handling to the
5764 server. Affected file silcd/server.c.
5768 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5770 * Added silc_server_send_notify_invite to send the INVITE
5771 notify between routers.
5773 * Implemented the INVITE command correctly to the server.
5775 * Implemented the INVITE notify type handling in the server.
5777 * Implemented the INVITE command to the client library and on the
5780 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5782 * Added function silc_server_get_client_resolve to find the
5783 client entry by ID from all ID lists and then resolve it
5784 (using WHOIS) if it cannot be found. Affected file is
5787 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5789 * Implemented the BAN command to the client library.
5791 * The JOIN command in the server now checks the invite list
5794 * Changed the silc_command_reply_payload_encode_va and the
5795 silc_command_payload_encode_va to support that if argument is
5796 NULL it ignores and checks the next argument. Affected file
5797 lib/silccore/silccommand.c.
5799 * Added silc_server_send_notify_ban to send the BAN notify
5800 type between routers.
5802 * Chaned the silc_notify_payload_encode to support that if
5803 argument is NULL it ignores and checks the next argument.
5804 Affected file lib/silccore/silcnotify.c.
5806 * Tested ban lists in router environment successfully.
5808 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5810 * Implemented BAN command to the server, in silcd/command.[ch].
5812 * Removed the BAN and INVITE_LIST modes from the CMODE command
5815 * Added function silc_string_match to regex match two strings.
5816 Affected files lib/silcutil/silcutil.[ch].
5818 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5820 * Redefined parts of the SilcChannelEntry in the server to support
5821 the new ban and invite lists.
5823 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5825 * Redefined the INVITE command. The same command can be used to
5826 invite individuals to the channel but also to manage the invite
5827 list of the channel (to add to and remove from the invite list).
5828 Updated the protocol specs.
5830 * Added new command SILC_COMMAND_BAN that can be used to manage
5831 the ban list of the channel. Updated the protocol specs.
5833 * Removed the channel modes: the SILC_CMODE_BAN and the
5834 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5835 in the CMODE command. The equivalent features are now available
5836 using INVITE and BAN commands. Updated the protocol specs.
5838 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5839 in the network about change in the current ban list. The notify
5840 type is not used by the client.
5842 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5843 support the invite lists.
5845 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5847 * Added new function silc_string_regexify that converts string
5848 including wildcard characters into regex string that can
5849 be used by the GNU regex library. Added into the file
5850 lib/silcutil/silcutil.[ch].
5852 Added silc_string_regex_combine to combine to regex strings
5853 into one so that they can be used as one regex string by
5854 the GNU regex library. Added into the file
5855 lib/silcutil/silcutil.[ch].
5857 Added silc_string_regex_match to match two strings. It returns
5858 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5860 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5862 * Imported GNU regex to the soruce tree into lib/contrib.
5863 Fixed some compiler warning from the regex.c.
5865 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5867 * Fixed MOTD command in the server to work in router environment.
5869 * Fixed the MOTD command in the client library to support
5870 the server argument in the command.
5872 * Added `nickname_len' argument to the silc_idlist_add_client
5873 in the server, as the `nickname' argument may be binary data
5876 * Added silc_idlist_get_channels to return all channels from
5879 * Implemented LIST command to the server. Affected file is
5882 * Implemented the LIST command to the client library and on the
5885 * Added [<user count>] argument to the LIST command reply.
5886 With private channels the user count is not shown.
5888 * Updated TODO and README.
5890 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5892 * The client entry's data.registered must be TRUE even with
5893 global client entry on global client list. The data.registered
5894 is used to check whether the client is anymore in the network,
5895 for example with WHOWAS command so it must be valid.
5897 * Fixed the WHOWAS command in the server. It now actually works
5898 in router environment. Added function into silcd/command_reply.c
5899 silc_server_command_reply_whowas_save.
5901 * Added silc_idlist_purge function to the silcd/idlist.c
5902 to periodically purge the ID Cache.
5904 * Fixed INFO command in the server. It works now in router
5905 environment. Added <server name> argument to the INFO command
5906 reply. Updated the protocol specs.
5908 * Fixed minor bug in silc_idcache_purge to not purge if the
5909 expire value is zero.
5911 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5912 they were buggy because of the WHOWAS information.
5914 * Fixed local command MSG to handle the async resolving of
5915 the remote client properly. It used to fail the first MSG.
5916 Affected file silc/local_command.c.
5918 * Added `data_len' field to SilcIDCache context.
5920 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5922 * Update TODO. Todo in commands in the server.
5924 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5926 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5927 used by routers as broadcast packet to inform other routers
5928 about the changed user mode.
5930 Implemented the notify handling in the server. Affected file is
5931 silcd/packet_receive.c. Added the function
5932 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5934 * Added new generic Channel Payload and deprecated the New Channel
5935 Payload. The New Channel Payload is now the generic Channel
5938 * Added new argument `mode' to the silc_server_send_new_channel
5939 as it is required in the Channel Payload now.
5941 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5942 and created a new and real SilChannelPayload to represent the
5943 new generic Channel Payload. Implemented the encode/decode
5944 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5946 * Added silc_server_get_client_channel_list to return the list
5947 of channels the client has joined for WHOIS command reply.
5948 Affected file silcd/server.[ch].
5950 * Implemented the channel list sending in the WHOIS command reply
5951 in server and in the client.
5953 Implemented the channel list displaying on the user interface
5954 as well. Affected file silc/client_ops.c.
5956 * Added silc_channel_payload_parse_list to parse list of Channel
5957 Payloads. It returns SilcDList list of SilcChannelPayloads.
5958 Client for example can use this function to parse the list of
5959 channels it receives in the WHOIS command reply. The caller
5960 must free the list by calling silc_channel_payload_list_free.
5961 Affected files lib/silccore/silcchannel.[ch].
5963 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5965 * Added one new argument <user mode> to the WHOIS command reply
5966 to return the mode of the user in SILC. Updated the protocol
5969 Implemented it to the server and client.
5971 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5973 * Fixed the mode printing on the user interface on joining.
5974 Affected file silc/client_ops.c.
5976 * Implemented the UMODE command and user modes in general to the
5977 client library and to the user interface.
5979 * Implemented the UMODE command to the server.
5981 * The server now sends UNKNOWN_COMMAND error status if client sends
5982 unknown command. Affected file silcd/command.c.
5984 * All server commands now handle the command identifier the right
5985 way when sending the command reply to the client. The client can
5986 use to identify the command replies with the identifier.
5988 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5990 * Added silc_server_get_client_route to resolve the route to
5991 the client indicated by the client ID. Affected file is
5994 * Added silc_server_relay_packet as general function to relay
5995 packet to arbitrary destination. This deprecates functions
5996 like _send_private_message_key, _relay_notify etc. Affected
5997 file is silcd/packet_send.[ch].
5999 Removed silc_server_send_key_agreement,
6000 silc_server_send_private_message_key and
6001 silc_server_packet_relay_notify functions from the file
6002 silcd/packet_send.[ch].
6006 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
6007 server. Affected file silcd/packet_receive.[ch].
6009 * Implemented the KILL command to the client. Implemented the
6010 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
6011 Affected files lib/silcclient/command[_reply].c and
6012 lib/silcclient/client_notify.c. Implemented the KILL notify
6013 printing in the user inteface.
6015 * Fixed a lot silc_parse_nick memory leaks from the client
6016 library in the file lib/silcclient/command.c.
6018 * Changed the silc_server_send_notify_on_channels's `sender'
6019 argument from SilcSocketConnection to SilcClientEntry to
6020 check the sender as entry and not as connection object and not
6021 to send to the client provided as argument. The affected file
6022 is silcd/packet_send.[ch].
6024 * The notify packets that are destined directly to the client used
6025 to not to be processed by the server. Now changed that and the
6026 server processes all notify packets. After relaying the packet
6027 to the client the notify packet is processed in the server.
6029 * The silc_server_free_client_data now checks whether there is
6030 pending outgoing traffic for the client and purges the data to
6031 the network before removing the client entry.
6033 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6035 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
6036 an client is killed from the SILC Network. Updated the protocol
6039 Added new function silc_server_send_notify_killed to the
6040 silcd/packet_send.[ch].
6042 * Added function silc_server_packet_relay_notify to relay notify
6043 packets that are destined directly to a client. In this case
6044 the server does not process the notify packets but merely relays
6045 it to the client. Affected file silcd/packet_send.[ch].
6047 Added also silc_server_packet_process_relay_notify to check
6048 whereto relay the notify. Affected file is
6049 silcd/packet_receive.[ch].
6051 * Implemented the KILL command to the server.
6055 * Added the backup schema desgined last fall to the protocol
6056 specs for everyone to see. The specification is in the
6057 *-spec-xx.txt draft and the packet type definitions for the
6058 backup routers is in *-pp-xx.txt draft. Thusly, added also
6059 new packet type SILC_PACKET_CELL_ROUTERS.
6061 * A big security problem in the implementation discovered. The
6062 signoff of an client did not cause new channel key generation
6063 which it of course should've done. The channel keys must be
6064 always re-generated when client leaves (or signoffs) the channel.
6065 The silc_server_remove_from_channels funtion now handles
6066 the channel key re-generation.
6068 * Added `sender' argument to the silc_server_send_notify_on_channels
6069 to not to send the client provided as argument. Affected file
6070 silcd/packet_send.[ch].
6072 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6074 * Implemented OPER and SILCOPER commands into the server and
6077 * Added silc_auth_verify and silc_auth_verify_data to verify
6078 the authentication directly from the authentication payload.
6079 It supports verifying both passphrase and public key based
6080 authentication. Affected file lib/silccore/silcauth.[ch].
6082 * Added `hash' field to the SilcIDListData structure. It is the
6083 hash negotiated in the SKE protocol. Affected file is
6086 * Slight redesigning of the SilcAuthPayload handling routines.
6087 Do not send SilcPKCS but SilcPublicKey as argument.
6089 * Implemented the public key authentication support to the
6090 serverconfig. The public key is loaded from the provided path
6091 and saved as authentication data to void * pointer. Thus,
6092 changed the unsigned char *auth_data to void *auth_data;
6094 * Fixed SHUTDOWN command to send the reply before the server
6095 is shutdown. :) Affected file silcd/command.c.
6097 * Fixed fatal bug in CONNECT command. The hostname was invalid
6098 memory and server crashed. Affected file silcd/command.c.
6100 * Fixed fatal bug in CLOSE command. The server_entry became
6101 invalid but was referenced later in the command. Affected file
6104 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6106 * Fixed fatal bug in failure packet handling. Server ignored
6107 the failure and thus crashed when it came.
6111 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6113 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
6114 that the command may be executed only once in (about) 2 seconds.
6115 The old SILC_CF_LAG flag is same but allows command bursts up
6116 to five before limiting.
6118 Added the support for CF_LAG and CF_LAG_STRICT flags to the
6119 server code. Various commands now includes the CF_LAG_STRICT
6120 flag to disallow any kind of miss-use of the command.
6122 * Fixed the silc_buffer_unformat to not to allocate any data
6123 if the length of the data is zero. It used to allocate the
6124 length + 1. Affected file lib/silcutil/silcbuffmt.c.
6126 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6128 * Changed the format of AdminConnection configuration section
6129 in the server. Added username of the admin to the format.
6130 Affected files silcd/serverconfig.[ch].
6132 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
6133 to return admin configuration data by host, username and/or
6136 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6138 * Implemented WHOWAS command to the server. Added the functions:
6140 silc_server_command_whowas_parse,
6141 silc_server_command_whowas_send_reply,
6142 silc_server_command_whowas_from_client and
6143 silc_server_command_whowas_from_server
6145 * Added <Client ID> argument to the WHOWAS command reply. Updated
6146 the protocol specs accordingly.
6148 * Implemented WHOWAS command and command_reply to the client
6151 Implemented the WHOWAS printing on the user interface.
6153 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6155 * Added new argument to the WHOWAS command reply, the real name.
6156 It is an optional argument. Updated the protocol specs.
6158 * Added SilcIDCacheDestructor callback that is registered when
6159 the SilcIDCache is allocated. The callback is called when
6160 an cache entry in the ID Cache expires, or is purged from the
6161 cache. Added into lib/silccore/idcache.[ch].
6163 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
6164 to destruct the client entries when the cache entry expires.
6165 Other ID Cache's in server and in the client library ignores
6168 * If the ID Cache entry's `expire' field is zero then the entry
6169 never expires. Added boolean `expire' argument to the
6170 silc_idcache_add function in the lib/silccore/idcache.[ch].
6171 If it is TRUE the default expiry value is used.
6173 * Added silc_server_free_client_data_timeout that is registered
6174 when client disconnects. By default for 5 minutes we preserve
6175 the client entry for history - for WHOWAS command.
6177 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6179 * Added support to the server to enforce that commands are not
6180 executed more than once in 2 seconds. If server receives
6181 commands from client more frequently, timeout is registered
6182 to process the commands. Affected file silcd/command.c.
6183 Added new function silc_server_command_process_timeout.
6185 * Changed NICK_NOTIFY handling in client library to check that
6186 if the client's nickname was changed, so there is no need to
6187 resolve anything from the server.
6189 * Removed error printing from the WHOIS and IDENTIFY commands.
6190 If error occurs then it is ignored silently in the client library.
6191 The application, however, may map the received error to
6192 human readable error string. The application currently maps
6193 the NO_SUCH_NICKNAME error to string.
6195 * Made the command status message public to the application. Moved
6196 them from lib/silcclient/command_reply.c to
6197 lib/silcclient/command_reply.h. The application can map the
6198 received command status to the string with the
6199 silc_client_command_status_message function.
6201 * Added check to the server to check that client's ID is same
6202 as the Source ID in the packet the client sent. They must
6205 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6207 * Added dist-bzip hook to the Makefile.am to make bzip2
6208 compressed distributions.
6210 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6212 * Server now enforces the maximum length for the nickname and
6213 the channel as protocol specification dictates. 128 bytes for
6214 nickname and 256 bytes for channel name.
6216 * Moved the WHOIS printing to the application. The client libary
6217 does not print out the WHOIS information anymore, the application
6218 must do it. Renamed silc_client_command_reply_whois_print to
6219 the silc_client_command_reply_whois_save.
6221 The client's idle time is also sent to the application now, and
6222 the idle is shown on screen.
6224 * Added silc_client_command_reply_identify_save to save the
6225 received IDENTIFY entries.
6227 * Do not check for channel private keys in message sending and
6228 reception if the channel does not have the PRIVKEY mode set.
6229 Affected file lib/silclient/client_channel.c.
6231 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6233 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
6234 just surfaced after chaning the JOIN procedure.
6236 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6238 * Added silc_client_get_clients_by_list to get client entries
6239 from Client ID list, that is returned for example by JOIN
6240 and USERS command replies. The application should use this
6241 function for example when JOIN command reply is received to
6242 resolve the clients already on the channel (library does not
6243 do that anymore as USERS command reply is not used in the JOIN
6244 procedure anymore). Affected files lib/silcclient/silcapi.h and
6245 lib/silcclient/idlist.c.
6247 * JOIN command reply and USERS command reply returns now SilcBuffer
6248 pointers instead of unsigned char pointers when returning
6249 the client list and mode list.
6251 * Added <Client ID> argument to the JOIN command reply, mainly
6252 for the server to identify for which client the command was
6253 originally sent. Updated protocol specs accordingly.
6255 * Added SilcDlist private_key pointer to the SilcChannelEntry
6256 in the client to support the channel private keys. Affected
6257 file is lib/silcclient/idlist.h.
6259 * Added SilcChannelPrivateKey argument to the function
6260 silc_client_send_channel_message so that application can choose
6261 to use specific private ke if it wants to. If it is not provided,
6262 the normal channel key is used, unless private keys are set.
6263 In this case the first (key that was added first) is used
6264 as the encryption key.
6266 * Implemented the support for channel private key handling.
6267 Implemented the following functions:
6269 silc_client_add_channel_private_key,
6270 silc_client_del_channel_private_keys,
6271 silc_client_del_channel_private_key,
6272 silc_client_list_channel_private_keys and
6273 silc_client_free_channel_private_keys
6275 Affected file lib/silcclient/client_channel.c.
6277 * Added the support for the private keys in the channel message
6278 sending and encryption and in the message reception and
6279 decryption. Affected funtions are
6280 silc_client_send_channel_message and silc_client_channel_message.
6282 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6284 * Added SKE's key verify callback to the client library's
6285 KE protocol context. Affected files lib/silcclient/protocol.[ch].
6287 * Removed the statement that server (or router) must send USERS
6288 command reply when joining to the channel so that the client
6289 knows who are on the channel. Instead, the client list and
6290 client's mode list is now sent in the JOIN command reply to the
6291 client who joined channel. This is better solution.
6293 * Added function silc_server_get_users_on_channel and function
6294 silc_server_save_users_on_channel to the silcd/server.[ch].
6296 * Removed function silc_server_command_send_users from the
6299 * Do not show topic on the client library anymore. The topic is
6300 sent in the command reply notify to the application and the
6301 application must show the topic now.
6303 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6305 * Added client searching by nickname hash into the IDENTIFY and
6306 WHOIS commands in the server as they were clearly missing from
6307 them. Affected file is silcd/command.c.
6309 * Fixed a bug in private message receiving in the client library.
6310 The remote ID was freed and it wasn't supposed, now it is
6313 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6315 * Minor fix to the channel payload; allocate the data area, as it
6316 needs to be of specific length.
6318 * If the key agreement port is zero then the operating
6319 system will define the bound port. Affected files are
6320 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
6322 * Added new function silc_channel_payload_decrypt into the file
6323 lib/silccore/silcchannel.[ch].
6325 * Moved the channel message etc, check from silc_packet_decrypt
6326 to applications. The library calls now a generic
6327 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
6328 when the packet is either normal or special. This was done to
6329 allow more wide range of checking that was not allowed when
6330 the code was in library. Now applications can do virtually any
6331 checks to the packet and return to the library the decision how
6332 the packet should be processed. Affected files are
6333 lib/silccore/silcpacket.[ch].
6335 Added silc_server_packet_decrypt_check to the server and
6336 silc_client_packet_decrypt_check to the client library.
6338 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
6339 to send with specified source and destination information.
6341 * Channel message delivery between routers was broken after the
6342 channel key distribution was fixed earlier. The channel key
6343 was used be to distributed to other routers as well which is not
6344 allowed by the protocol. Now this is fixed and channel keys
6345 really are cell specific and the channel message delivery between
6346 routers comply with the protocol specification.
6348 * Fixed various commands in server to check also the global list
6349 for the channel entry and not just the local list. The affected
6350 file silcd/command.c.
6352 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6354 * Added assert()s to buffer formatting and unformatting routines
6355 to assert (if --enable-debug) when error occurs. Affected
6356 file: lib/silcutil/silcbuffmt.c.
6358 * Changed to auto-reconnect to check whether the remote host is
6359 router and register the re-connect timeout if it is. It used
6360 to check that whether we are normal server, but router must do
6361 auto-reconnect with another router as well. Affected file
6364 * Removed the [<key len>] option from CMODE command as the cipher
6365 name decides the key length, nowadays. See the defined ciphers
6366 from the protocol specification.
6368 * Added [<hmac>] option to the CMODE command to define the HMAC
6369 for the channel. Added SILC_CMODE_HMAC channel mode.
6371 * Added [<hmac>] option for the JOIN command so that user can
6372 select which HMAC is used to compute the MACs of the channel
6375 * Added Hmac field to the Channel Message Payload. The integrity
6376 of plaintext channel messages are now protected by computing
6377 MAC of the message and attaching the MAC to the payload. The
6378 MAC is encrypted. Now, it is clear that this causes some
6379 overhead to the size of the packet but rationale for this is that
6380 now the receiver can verify whether the channel message decrypted
6381 correctly and also when private keys are set for the channel the
6382 receiver can decrypt the packet with several keys and check from
6383 the MAC which key decrypted the message correctly.
6385 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
6386 lib/silccrypt/silccipher.[ch].
6388 * Added silc_hash_len to return the digest length into the
6389 lib/silcrypt/silchash.[ch].
6391 * Rewrote parts of Silc Channel Payload interface in the
6392 lib/silccore/silcchannel.[ch]. The encode function now also
6393 encrypts the packet and parse function decrypts it.
6395 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6397 * Fixed a minor formatting bug in the SKE's key material processing.
6398 It actually might have processed the keys wrong way resulting
6401 * Redefined the mandatory HMAC algorithms and added new algorithms.
6402 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
6403 and hmac-md5 truncated to 96 bits. The mandatory is now
6404 hmac-sha1-96. Rest are optional (including the one that used
6405 to be mandatory). Rationale for this is that the truncated HMAC
6406 length is sufficient from security point of view and can actually
6407 make the attack against the HMAC harder. Also, the truncated
6408 HMAC causes less overhead to the packets. See the RFC2104 for
6411 * Added new [hmac] configuration section. The SKE used to use
6412 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
6413 is of course wrong. The official names that must be proposed in
6414 the SKE are the ones defined in the protocol specification
6415 (hmac-sha1-96 for example). The user can configure any hmac
6416 using any hash function configured in the [hash] section. At
6417 least, the mandatory must be configured.
6419 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
6421 * Added HMAC list to the SKE proposal list. It has now both
6422 hash algorithm list and HMAC list. This makes the protocol
6423 incompatible with previous versions. The SKE now seems to work
6424 the way it is supposed to work, for the first time actually.
6426 * Defined plain Hash algorithms to the protocol specification.
6429 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6431 * Implemented support for key agreement packets into the server.
6432 Added functions silc_server_key_agreement and
6433 silc_server_send_key_agreement. Other than these functions,
6434 server has nothing to do with this packet.
6436 * Added support for private message key packets into the server.
6437 Added functions silc_server_private_message_key and
6438 silc_server_send_private_message_key.
6442 * Changed the silc_[client|server]_protocol_ke_set_keys to be
6443 called in the protocol's final callback instead in the END
6444 protocol state. This makes a little more sense and in the same
6445 time in client we can use the same protocol routines for normal
6446 key exchange and to key agreement packet handling as well.
6448 * Added to both client's and server's KE protocol context the
6449 SilcSKEKeyMaterial pointer to save the key material. We will
6450 bring the key material to the protocol's final callback by doing
6451 this. The final callback must free the key material.
6453 * Added SKE's packet_send callback into client's KE protocol
6454 context so that the caller can choose what packet sending function
6455 is used. This way we can use different packet sending when
6456 doing normal SKE when doing key agreement packet handling (in
6457 the key agreement packet handling we do not want to encrypt
6460 * Implemented the responder side of the key agreement routines
6461 in the client. The client can now bind to specified port and
6462 accept incoming key negotiation. The key material is passed
6463 to the application after the protocol is over.
6465 * Implemented the processing of incoming Key Agreement packet
6466 in the client. Added function silc_client_key_agreement to
6469 * Implemented the intiator side of the key agreement routines
6470 in the client. The client can now initiate key agreement with
6471 another remote client. The key material is passed to the
6472 application after the protocol is over.
6474 * Created client_keyagr.c to include all the key agreement
6477 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
6478 SILC_TASK_CALLBACK except that it is not static.
6480 * Created client_notify.c and moved the Notify packet handling
6481 from the client.[ch] into that file.
6483 * Created client_prvmsg.c and moved all private message and
6484 private message key routines from the client.[ch] into that file.
6486 * Create client_channel.c and moved all channel message and
6487 channel private key routines from the client.[ch] into that file.
6489 * Changed silc_client_get_client_by_id_resolve to resolve with
6490 WHOIS command instead of IDENTIFY command, in the file
6491 lib/silclient/idlist.c.
6493 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6495 * Implemented the SKE's responder side to the Client library.
6497 * When FAILURE is received to the protocol do not trust it
6498 blindly. Register a timeout to wait whether the remote closes
6499 the connection as it should do it, only after that process the
6500 actual failure. This was changed to both client and server.
6502 * Added client_internal.h to include some of the structures
6503 there instead of client.h in lib/silcclient/.
6505 * Added function silc_task_unregister_by_callback to unregister
6506 timeouts by the callback function.
6508 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6510 * Some "Incomplete WHOIS info" errors has been appearing on the
6511 log files. Took away the entry->userinfo check from WHOIS
6512 reply sending. The entry->userinfo is now " " if client did not
6513 provide one. I thought this was fixed earlier but something
6514 is wrong still. Let's see if the error still appears.
6516 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6518 * Fixed a minor bug in the login when the channel key is
6519 re-generated in the server. It used to generate the key in
6520 wrong order and thus caused problems in the channel traffic.
6522 * Fixed a minor bug in channel key distsribution after
6523 KICK command. The key was not sent to the router even though
6526 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6528 * Added silc_ske_process_key_material_data as generic routine
6529 to process any key material as the SILC protocol dictates. The
6530 function is used by the actual SKE library but can be used by
6531 applications as well. This relates to the private message keys
6532 and the channel private keys since they must be processed the
6533 same way the normal SILC session keys. The protocol dictates
6534 this. Affected files: lib/silcske/silcske.[ch].
6536 Added also silc_ske_free_key_material to free the
6537 SilcSKEKeyMaterial structure.
6539 * Defined silc_cipher_set_key function to set the key for
6540 cipher without using the object's method function. The affected
6541 files: lib/silccrypt/silccipher.[ch].
6543 * Implemented silc silc_client_add_private_message_key,
6544 silc_client_add_private_message_key_ske,
6545 silc_client_del_private_message_key,
6546 silc_client_list_private_message_keys and
6547 silc_client_free_private_message_keys functions in the
6550 Added functions silc_client_send_private_message_key to send
6551 the Private Message Key payload and silc_client_private_message_key
6552 to handle incoming Private Message Key payload.
6554 * Added Cipher field to the Private Message Key payload to set
6555 the cipher to be used. If ignored, the default cipher defined
6556 in the SILC protocol (aes-256-cbc) is used.
6558 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6560 * Removed lib/silcclient/ops.h file.
6562 Redefined parts of the SILC Client Library API. Created new
6563 file silcapi.h that deprecates the ops.h file and defines the
6564 published Client Library API. Defined also private message key
6565 API and channel private key API into the file.
6567 This is the file that the application must include from the
6568 SILC Client Library. Other files need not be included by
6569 the application anymore.
6571 * Added new key_agreement client operation callback and also
6572 defined the Key Agreement library API for the application.
6574 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6576 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
6577 is used by clients to request key negotiation between another
6578 client in the SILC network. If the negotiation is started it
6579 is performed using the SKE protocol. The result of the
6580 negotiation, the secret key material, can be used for example
6581 as private message key.
6583 Implemented the Key Agreement payload into the files
6584 lib/silccore/silauth.[ch].
6586 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6588 * Redefined ciphers for the SILC protocol. Added some new ciphers
6589 and defined the key lengths for the algorithms. Changed the
6590 code accordingly. The default key length is now 256 bits.
6592 * Fixed SKE key distribution function silc_ske_process_key_material
6593 when the key length is more than 128 bits. The default key
6594 length in SILC is now 256 bits.
6596 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
6597 to indicate unsupported algorithm.
6599 * Renamed rijndael.c to aes.c and all functions as well.
6601 * Fixed a long standing channel key setting bug in client library.
6602 Weird that it has never surfaced before.
6604 * Fixed bug in channel deletion. If the entire channel is removed
6605 then it must also delete the references of the channel entry
6606 from the client's channel list as the client's channel entry and
6607 the channel's client entry share same memory.
6609 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6611 * Implemented CONNECT and SHUTDOWN commands in the client.
6613 * Implemented CLOSE command to the client.
6615 * Added the function silc_idlist_find_server_by_name into the
6616 files silcd/idlist.[ch].
6618 Added the function silc_idlist_find_server_by_conn into the
6619 files silcd/idlist.[ch].
6621 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6623 * DIE command was renamed to SHUTDOWN. Updated the both code
6626 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
6627 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
6629 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
6632 * Added function silc_server_create_connection function to create
6633 connection to remote router. My server implementation actually
6634 does not allow router to connect to normal server (it expects
6635 that normal server always initiates the connection to the router)
6636 so the CONNECT command is only good for connecting to another
6639 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6641 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
6642 or some other client was kicked from the channel.
6644 Implemented the handling of the notify type to both client
6647 Implemented silc_server_send_notify_kicked to send the KICKED
6648 notify. It is used to send it to the server's primary router.
6650 * Implemented the KICK command into server and client.
6652 * Added `query' argument to the silc_idlist_get_client function
6653 to indicate whether to query the client from server or not if
6656 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
6657 to indicate that the client is not channel founder.
6661 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6663 * Removed the rng context from SilcPacketContext structure and
6664 changed that the packet routine uses the Global RNG API.
6666 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6668 * Added support for quit message that client can "leave" on the
6669 channel when it quits the SILC. It is ditributed inside the
6670 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6672 Added silc_server_free_client_data that will take the
6673 signoff message as argument.
6675 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6677 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6679 * Updated parts of the protocol specification to keep it up
6682 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6684 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6685 payloads in one packet.
6687 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6688 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6689 use now the new List flag.
6691 * Also deprecated the following packet types: REPLACE_ID,
6692 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6694 * Added list support for Notify packet in server.
6696 * Added silc_server_send_notify_channel_change to send the
6697 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6698 the silc_server_send_replace_id.
6700 * Added silc_server_send_notify_nick_change to send the
6701 NICK_CHANGE notify type. Deprecates the function
6702 silc_server_send_replace_id.
6704 * Added silc_server_send_notify_join to send the JOIN notify type.
6705 Deprecates the function silc_server_send_new_channel_user.
6707 * Added silc_server_send_notify_leave to send LEAVE notify type.
6708 Deprecates the function silc_server_send_remove_channel_user.
6710 * Added silc_server_send_notify_cmode and
6711 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6712 types. Deprecates the silc_server_send_set_mode function.
6714 * Added SERVER_SIGNOFF notify type to indicate that server has
6715 quit. This means that all clients on the channel from that
6716 server will drop. This can be also used when netsplit happens.
6718 Deprecated REMOVE_ID packet type since it is not needed anymore
6721 Added silc_server_send_notify_server_signoff to send the
6722 SERVER_SIGNOFF notify type. Deprecates the function
6723 silc_server_send_remove_id.
6725 Added also silc_server_send_notify_signoff to send the
6726 SIGNOFF notify type.
6728 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6729 SILC protocol from this day on. Changed the protocol
6730 specification as well.
6732 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6733 notify type. It is used between routers to notify about
6734 topic changes on a channel.
6736 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6739 * Partly updated the protocol specification to comply with the
6740 changes now made. It is still though a bit outdated.
6742 * The JOIN notify type now takes one extra argument <Channel ID>.
6743 The packet used to be destined to the channel but now the
6744 JOIN type may be sent as list thus it is impossible to
6745 destine it to any specific channel. By adding this argument
6746 it is again possible.
6748 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6750 * Added CREDITS file. The CHANGES and CREDITS file will appear
6751 in the distribution as well.
6753 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6755 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6756 types in the server's silcd/packet_receive.c.
6758 * Implemented CMODE and CUMODE to work in router environment.
6760 * Fixed minor encoding and decoding buglet from the
6761 lib/silccore/silcmode.c.
6763 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6766 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6768 * Changed all SilcConfigServer* and silc_config_server* to
6769 SilcServerConfig* and silc_server_config*, respectively.
6772 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6774 * Associated the ID (client or server ID) to the Authentication
6775 Payload to avoid any possibility of forging. Updated the
6776 protocol specification and the code accordingly.
6778 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6780 * The RSA key length is now save to the RsaKey context in the
6781 key generation process in lib/silccrypt/rsa.c. The key length
6782 is now used to figure out the maximum size of the block allowed
6783 to be encrypted/signed.
6785 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6786 is equivalent to the silc_mp_mp2bin but does not allocate any
6789 * Changed silc_mp_mp2bin API to take length argument. If it is
6790 non-zero then the buffer is allocated that large. If zero, then
6791 the size is approximated using silc_mp_sizeinbase, which however
6794 * Created Global RNG API which is global RNG that application can
6795 initialize. After initializing, any routine anywhere in the
6796 code (including library) can use RNG without allocating a new
6797 RNG object. This was done to allow this sort of use of the
6798 RNG in code that has no chance to allocate RNG object. All
6799 applications currently allocate this and many routines in the
6800 library use this. Affected file lib/silccrypt/silcrng.[ch].
6802 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6803 it to use the Global RNG API.
6805 * Defined Authentication Payload into protocol specification that
6806 is used during SILC session to authenticate entities. It is
6807 used for example by client to authenticate itself to the server
6808 to obtain server operator privileges.
6810 Implemented this payload into the lib/silccore/silcauth.[ch].
6811 Implemented also routines for public key based authentication
6812 as the new protocol specification dictates.
6814 Moved definitions of different authentication methods from
6815 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6817 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6818 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6819 silc_pkcs_verify_with_hash functions into the file
6820 lib/silccrypt/silcpkcs.[ch].
6822 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6824 * The client entry's userinfo pointer must be always valid.
6825 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6826 will fail since it requires the userinfo. Now, the userinfo
6827 is allocated as "" if actual userinfo does not exist. Actually,
6828 it must exist and it is totally Ok to drop client connections
6829 that does not announce the userinfo. However, we will make
6830 this workaround for now.
6832 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6833 to return the remote port by socket.
6835 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6837 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6838 SILC_SERVER_PENDING_EXEC and added an new macro
6839 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6840 data or when error occurs while processing the pending command.
6842 Added new argument `destructor' into silc_server_command_pending
6843 and to the SilcServerCommandPending object. This destructor is
6844 now called after calling the pending callback or if error occurs
6845 immediately. If error occurs the actual pending callback won't
6846 be called at all - only the destructor. The destructor may be
6847 NULL if destructor is not needed.
6849 All this applies for client library code as well. Similar
6850 changes were made there as well for the pending commands.
6852 In the client, the application must now allocate the
6853 SilcClientCommandContext with the silc_client_command_alloc
6856 * Added reference counter to the SilcServerCommandContext. Added
6857 function silc_server_command_alloc and silc_server_command_dup
6860 Same type of functions added to the client library for the same
6863 * Removed the cmd_ident from IDListData away since it is now
6864 global for all connections. It is the command identifier used
6865 in command sending and with pending commands. The affected file
6868 * Added reference counter to the SilcSocketConnection objecet to
6869 indicate the usage count of the object. The object won't be
6870 freed untill the reference counter hits zero. Currently only
6871 server uses this, and client ignores it. The client must be
6872 set to use this too later. The affected files are
6873 lib/silccore/silcsockconn.[ch]. Added also the function
6874 silc_socket_dup to increase the reference counter.
6876 This was mainly added because it is possible that the socket
6877 is removed underneath of pending command or other async
6878 operation. Now it won't be free'd and proper DISCONNECTING
6879 flags, etc. can be set to avoid sending data to connection that
6880 is not valid anymore.
6882 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6883 the connection. After that it sets SILC_SET_DISCONNECTED.
6884 It is, however, possible that the socket data is not still freed.
6885 The silc_server_packet_process now checks that data is not
6886 read or written to connection that is DISCONNECTED. The socket
6887 get's freed when the reference counter hits zero.
6889 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6891 * Changed the client operation API: channel_message operation's
6892 `sender' is now the client entry of the sender, not the nickname
6893 and the `channel' is the channel entry, not the channel name.
6895 In the private_message operation the `sender' is now also the
6896 client entry of the sender not the nickname.
6898 Affected file is lib/silcclient/ops.h and all applications
6899 using the client operations.
6901 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6903 * Moved the calling of ops->connect() from connect_to_server_final
6904 into receive_new_id functin since that is the point when the
6905 client is actually allowed to send traffic to network. The
6906 affected file is lib/silcclient/client.c.
6908 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6910 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6911 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6912 (if needs broadcasting) instead of broadcasting the packets one
6913 by one which would make a burst in the network traffic.
6915 * Added `broadcast' argument to the functions in silcd/server.[ch]
6916 silc_server_create_new_channel[_with_id] to indicate whether
6917 to send New Channel packet to primary router.
6919 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6921 * Added new function into the silcd/server.[ch] files:
6922 silc_server_create_new_channel_with_id to create new channel with
6923 already existing Channel ID.
6925 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6926 lib/silccore/silcpacket.h. This packet is used t send list of
6927 Set Mode payloads inside one packet. Server uses this to set
6928 the modes for the channels and clients on those channels, that it
6929 announced to the router when it connected to it. The protocol
6930 specification has been updated accordingly.
6932 * The silc_server_new_channel did not handle the packet coming
6933 from normal server as it normally does not send that. However,
6934 when it announces its channels it does send it. Implemented
6935 the support for that.
6937 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6938 into the file lib/silccore/id.h.
6940 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6942 * Fixed memory leaks in the functions silc_idlist_del_client,
6943 silc_idlist_del_channel and silc_idlist_del_server in the file
6944 silcd/idlist.c. All of those leaked like a sieve.
6946 * Fixed some small memory leaks in the client's function
6947 silc_client_notify_by_server.
6949 * Added functions into silcd/server.c: silc_server_announce_clients,
6950 silc_server_announce_channels and silc_server_announce_server.
6951 These functions are used by normal and router server to announce
6952 to its primary router about clients, channels and servers (when
6953 router) that we own. This is done after we've connected to the
6956 These functions effectively implements the following packet types:
6957 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6958 and SILC_PACKET_NEW_ID_LIST.
6960 * Added new functions into the silcd/packet_receive.[ch]:
6961 silc_server_new_id_list, silc_server_new_channel_list and
6962 silc_server_new_channel_user_list to handle the incoming
6963 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6965 * Added support of changing Channel ID in the function
6966 silc_server_replace_id. If the server that announces a channel
6967 to the router already exists in the router (with same name but
6968 with different Channel ID), router is responsible to send
6969 Replace ID packet to the server and force the server to change
6970 the Channel ID to the one router has.
6972 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6973 client that the Channel ID has been changed by the router. The
6974 normal server sends this to the client. Client must start using
6975 the new Channel ID as the channel's ID.
6977 Implemented handling of this new type into lib/silcclient/client.c
6978 into the function silc_client_notify_by_server.
6980 * Added new function silc_idlist_replace_channel_id into the files
6981 silcd/idlist.[ch] to replace the Channel ID.
6983 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6985 * Call silc_server_command_identify_check always when processing
6986 the IDENTIFY command in silcd/command.c
6988 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6990 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6991 send keepalive packets. The packet can be sent by clients,
6992 servers and routers.
6994 Added function silc_socket_set_heartbeat into the file
6995 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6996 If not set, the heartbeat is not performed. The actual
6997 heartbeat is implemented in the low level socket connection
6998 library. However, application is responsible of actually
7001 Added silc_server_send_heartbeat to send the actual heartbeat
7002 packet into silcd/packet_send.[ch]. Server now performs
7003 keepalive with all connections.
7005 * Added silc_task_get_first function into lib/silcutil/silctask.c
7006 to return the timeout task with shortest timeout. There was a bug
7007 in task unregistration that caused problems. TODO has been
7008 updated to include that task system must be rewritten.
7010 * The client library will now resolve the client information when
7011 receiving JOIN notify from server for client that we know but
7012 have incomplete information.
7014 * Rewrote parts of silc_server_remove_from_channels and
7015 silc_server_remove_from_one_channel as they did not remove the
7016 channel in some circumstances even though they should've.
7018 * Encryption problem encountered in server:
7020 The LEAVE command used to send the Channel Key packet to the
7021 router immediately after generating it. However, the code
7022 had earlier sent Remove Channel user packet but not immediately,
7023 ie. it was put to queue. The order of packets in the router
7024 was that Channel Key packet was first and Remove Channel User
7025 packet was second, even though they were encrypted in the
7026 reverse order. For this reason, MAC check failed. Now, this
7027 is fixed by not sending the Channel Key packet immediately but
7028 putting it to queue. However, this is more fundamental problem:
7029 packets that are in queue should actually not be encrypted
7030 because packets that are sent immediately gets encrypted
7031 actually with wrong IV (and thus MAC check fails). So, packets
7032 that are in queue should be encrypted when they are sent to
7033 the wire and not when they put to the queue.
7035 However, the problem is that the current system has not been
7036 designed to work that way. Instead, the packet is encrypted
7037 as soon as possible and left to the queue. The queue is then
7038 just purged into wire. There won't be any fixes for this
7039 any time soon. So, the current semantic for packet sending
7042 o If you send packet to remote host and do not force the send
7043 (the packet will be in queue) then all subsequent packets to the
7044 same remote host must also be put to the queue. Only after the
7045 queue has been purged is it safe again to force the packet
7048 o If you send all packets immediately then it safe to send
7049 any of subsequent packets through the queue, however, after
7050 the first packet is put to queue then any subsequent packets
7051 must also be put to the queue.
7053 Follow these rules and everything works fine.
7055 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7057 * Added new function silc_server_remove_clients_by_server to
7058 remove all client entries from ID list when the server connection
7059 is lost. In this case it is also important to invalidate all
7060 client entires as they hold the invalid server entry. This
7061 fixes fatal bug when server has lost connection and will reconnect
7064 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7066 * Made some sanity checks to silc_server_daemonise like to check
7067 whether the requested user and group actually exists.
7069 * Added sanity check to SKE's silc_ske_responder_finish to check
7070 that the public and private key actually is valid.
7072 * Invalidate the client's nickname when receiving Replace ID
7073 packet and the Client ID is being replaced. This means that the
7074 server will query the nickname if someone needs it (client)
7077 * Sort the ID Cache in client library when the ID Cache data
7078 has changed (needs sorting).
7080 * Do not allow for SILC client to create several connections to
7081 several servers. The client does not support windows right now
7082 and generating multiple connections causes weird behaviour.
7084 Irssi-silc client does support windows and can handle several
7085 connections without problems, see: www.irssi.org and SILC plugin.
7087 * Fixed some places where client was added to the IDList. The
7088 rule of thumb is following (in order to get everything right):
7089 If the client is directly connected local client then the
7090 `connection' argument must be set and `router' argument must be
7091 NULL to silc_idlist_add_client function. If the client is not
7092 directly connected client then the `router' argument must
7093 bet set and the `connection' argument must be NULL to the
7094 silc_idlist_add_client function.
7096 * The funtion silc_server_packet_send_local_channel actually did
7097 not check whether the client was locally connected or not. It
7098 does that now. Fixed a bug related to LEAVE command.
7100 * Fixed Remove Channel User payload parsing bug in server's
7101 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
7103 * The server's silc_server_save_channel_key now checks also the
7104 global ID list for the channel as it might not be in the local
7105 list. Fixed a bug related to LEAVE command.
7107 * Is this the end of the [<unknown>] buglet that has been lurking
7108 around for a long time? A little for loop fix in server's
7109 silc_server_command_whois_parse that is used by both IDENTIFY
7110 and WHOIS command. At least, this was a clear bug and a cause
7111 of one type of [<unknown>] buglet.
7113 * WHOIS and IDENTIFY commands call the function
7114 silc_server_command_[whois/identify]_check function even if
7115 we are not router server.
7117 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7119 * Added --with-gmp configuration option. If set the GMP
7120 is always compiled in the SILC source tree. If not set then
7121 it is checked whether the system has the GMP3 installed. If
7122 it has then the GMP won't be compiled (the system's headers
7123 and library is used), if it doesn't have it then the GMP is
7124 compiled in the SILC source tree.
7126 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7128 * Changed RSA private exponent generation to what PKCS #1
7129 suggests. We try to find the smallest possible d by doing
7130 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
7131 not security fix but optimization.
7133 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7135 * Added new config entry [Identity] to fork the server and run
7136 it as specific user and group. A patch from Bostik.
7138 * Imported Dotconf configuration library into lib/dotconf.
7139 This will be used to create the SILC configuration files later.
7140 It will appear in the distsribution after this commit.
7142 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7144 * A big code auditing weekend happening. Auditing code for
7145 obvious mistakes, bugs and errors. Also, removing any code
7148 Removed files for being obsolete:
7150 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
7151 inline in the file lib/silcutil/silcbuffer.h)
7153 o lib/silcutil/silcbufutil.c (the header has inline versions)
7155 Changed code to fix possible error conditions:
7157 o The buffer formatting routines now check that the destination
7158 buffer really has enough space to add the data. This applies for
7159 both buffer formatting and unformatting
7160 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
7161 unformatting was changed to accomodate following rules:
7162 XXX_*STRING_ALLOC will allocate space for the data into the pointer
7163 sent to the function while XXX_*STRING will not allocate or copy
7164 the data into the buffer. Instead it sets the pointer from the
7165 buffer into the pointer sent as argument (XXX_*STRING used to
7166 require that the pointer must be allocated already). This change
7167 makes this whole thing a bit more consistent and more optimized
7168 (note that the data returned in the unformatting with XXX_*STRING
7169 must not be freed now). The routines return now -1 on error.
7171 o Tried to find all code that use buffer_format and buffer_unformat
7172 and added return value checking to prevent formatting and
7173 especially unformatting errors and possible subsequent fatal
7176 o Changed ske->x and ske->KEY to mallocated pointers in
7177 lib/silcske/silcske.h. Fixed possible data and memory leak.
7179 o Added return value checking to all *_parse* functions. Fixed
7180 many memory leaks as well.
7182 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
7183 so that buffer overflows would not happen. All code now also
7184 checks the return value as it can fail.
7186 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7188 * Added reconnection support to server if the normal server looses
7189 its connection to the router (for example if router is rebooted).
7190 The server performs normal reconnection strategy implemented
7191 to the server. Affected file silcd/server.c.
7193 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7195 * Added new packet type SILC_PACKET_SET_MODE that is used to
7196 distribute the information about changed modes (for clients,
7197 channels and clients channel modes) to all routers in the
7198 network. Updated the protocol specification accordingly.
7200 Added functions into silcd/packet_send.c and
7201 silcd/packet_receive.c: silc_server_send_set_mode,
7202 silc_server_set_mode.
7204 Added new files silcmode.[ch] into lib/silccore that implements
7205 the encoding and decoding of Set Mode Payload. Added new type
7206 SilcSetModePayload. Moved the definitions of different modes
7207 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
7209 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7211 * Oops, a little mistake in server's connection authentication
7212 protocol. The protocol is not ended with FAILURE but with
7213 SUCCESS if the authentication is Ok. :) Affected file is
7216 * Implemented NICK_CHANGE notify handling in server in the file
7217 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
7218 the local clients on the channel. After the changing nickname
7219 in router environment snhould work and the [<unknown>] nickname
7220 should appear no more.
7222 The silc_server_replace_id function that receives the Replace ID
7223 payload now sends the NICK_CHANGE notify type also in the file
7224 silcd/packet_receive.c
7226 * Changed WHOIS and IDENTIFY command to support the maximum amount
7227 of arguments defined in protocol specs (3328 arguments). This
7228 fixed a bug that caused problems when there were more than three
7231 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7233 * Added extra parameter, command identifier, to the
7234 silc_client_send_command so that explicit command identifier
7237 Changed that ID list routines uses specific command identifier
7238 when sending WHOIS/IDENTIFY requests to the server so that they
7239 can be identified when the reply comes back.
7241 Affected files lib/silcclient/command.[ch],
7242 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
7244 * Added `sender' argument to silc_server_packet_send_to_channel
7245 to indicaet the sender who originally sent the packet to us
7246 that we are now re-sending. Ignored if NULL. Affected file
7247 silcd/packet_send.[ch].
7249 * Added some server statistics support in silcd/server_internal.h
7250 SilcServerStatistics structure and around the server code. Also
7251 send some nice statistics information when client is connecting
7254 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7256 * Fixed channel ID decoding in server's JOIN command reply in
7257 silcd/command_reply.c
7259 * Fixed braodcasting of replace ID payload to not to send it if
7260 we are standalone server in silcd/packet_receive.c.
7262 * Fixed all channel message sending routines to not to send
7263 packets to clients that has router set, since they are routed
7264 separately in the same function earlier. Affects file
7265 silcd/packet_send.c and all channel packet sending functions.
7267 * In USERS reply, res_argv[i] are not allocated, the table
7268 is allocated. Thus changed that free the table, not its
7271 * In server's whois_check and identify_check if the client is
7272 locally connected do not send any WHOIS commands - they are not
7275 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7277 * Fixed some minor bugs in client when sending WHOIS command. The
7278 arguments was in wrong order.
7280 * Removed statis function add_to_channel from server in
7281 silcd/command.c that was previously used with the joining but
7284 * Tested USERS command in router environment successfully with two
7285 routers, two servers and two clients.
7287 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7289 * Reorganized the USERS command and command reply in client library
7290 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
7291 When the command is given by user we register a pending command
7292 callback that will reprocess the command after the reply has been
7293 received from the server. When reprocessing the packet we then
7294 display the information. Thus, the USERS information is displayed
7295 now in the command callback instead of in the command reply
7296 callback. The processing of the command is same as previously
7297 when server has sent the command reply in the JOINing process.
7299 * Added to USERS command in silcd/command_reply.c to join the client,
7300 we didn't use to know about, to the channel after we've created
7301 a client entry for it. Also, for clienet we did know already still
7302 check whether it is on the channel or not and add it if not.
7304 * Removed silc_server_command_join_notify as the function and its
7307 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7309 * Changed the client's pending command handling to the same as the
7310 server's pending command handling. It is also now possible to
7311 execute command reply functions from other command reply
7312 function as the function callbacks for commands and command
7313 replies are one and same. The pending commands are not static
7314 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
7315 in client connection context. Thus, pending commands are server
7316 connection specific as it is convenient.
7318 Changed the function silc_client_command_pending and
7319 silc_client_command_pending_del and added new function
7320 silc_client_command_pending_check. Removed the
7321 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
7324 * Added cmd_ident, current command identifier, to the client
7325 connection context in lib/silcclient/client.h to keep track on
7326 command identifiers used in command sending. Client's command reply
7327 function handling now supports the mandatory command identifiers.
7329 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
7330 funtions in client to fully support pending command callbacks.
7332 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
7333 as one of the arguments to the application in the command reply
7336 * NOTE: The FORWARDED flag is depracated. It used to be depracated
7337 before first releasing SILC but came back. Now it is removed again
7338 and should come back nomore. The FORWARDED flag was used only
7339 by the JOINing procedure by forwarding the command packet to router.
7340 Now, the JOINing procedure has been changed to more generic (due
7341 to various router environment issues) and FORWARDED is not needed
7342 anymore for anything. The protocol specification is yet to be
7345 Now, removed silc_server_packet_forward from server and the flag
7346 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
7348 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7350 * Renamed NAMES command to USERS command. The NAMES was named that
7351 due to historical reasons. Now it is renamed. Also, rewrote
7352 parts of the USERS command. The nickname list is not sent anymore
7353 by the server. Only Client ID and mode lists are sent in the USERS
7354 command. Changed this also to the protocol specification.
7356 The client now resolves the names and stuff after it receives
7357 the USERS list from the server when joining to the channel.
7359 * WHOIS and IDENTIFY commands has been changed to support multiple
7360 Client ID's per command. One can now search for multiple users
7361 in the network by sending only one WHOIS or IDENTIFY command.
7362 Changed the code and the protocol specifications.
7364 * Removed silc_server_command_identify_parse and changed that IDENTIFY
7365 uses silc_server_command_whois_parse to parse the request. */
7367 * If normal server, do not parse the WHOIS and IDENTIFY requests
7368 before sending it to the router. Saves some time.
7370 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7372 * Fixed JOIN command on client library. Wrong number of arguments
7373 used to crash the client.
7375 * Added silc_server_channel_has_global function to check whether
7376 channel has global users or not.
7378 * Added silc_server_channel_has_local function to check whether channel
7379 has locally connected clients on the channel.
7381 * The silc_server_remove_from_one_channel now checks whether the
7382 channel has global users or not after given client was removed from
7383 the channel. It also checks whether the channel has local clients
7384 on the channel anymore. If it does not have then the channel entry
7385 is removed as it is not needed anymore.
7387 * The silc_server_notify now checks on JOIN notify whether the joining
7388 client is one of locally connected or global. If it is global then
7389 the channel has now global users on the channel and that is marked
7390 to the channel entry. Also, it now saves the global client to
7391 global list who is joining and JOINs it to the channel. This is
7392 for normal server, that is.
7394 Changed silc_server_send_notify_on_channel,
7395 silc_server_packet_relay_to_channel and
7396 silc_server_packet_send_to_channel check if we are normal server
7397 and client has router set (ie. global client) do not send the
7398 message to that client, as it is already routed to our router.
7400 * Implemented LEAVE notify type handling in silc_server_notify
7403 * Tested LEAVE command in router environment successfully. Tested
7404 with two routers, two servers and two clients.
7408 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
7410 * Implemented SIGNOFF notify type handling in silc_server_notify
7413 * silc_server_remove_id now removes the client entry from all channels
7414 it has joined and thusly sends SIGNOFF notify type.
7416 * Rewrote the NAMES list generation in server by removing two excess
7417 loops. The lists are created now inside one loop.
7419 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7421 * silc_server_remove_channel_user checks now also global list
7422 for channel and client.
7424 * silc_server_new_channel_user checks now both local and global
7425 list for channel and client. Fixed a bug in client id decoding.
7426 Used to decode wrong buffer.
7428 * silc_server_channel_message checks now both local and global
7429 list for channel entry.
7431 * Tested channel joining (hence JOIN) in router environment
7432 successfully. Tested with two routers, two servers and two
7435 * Tested channel message sending in router environment successfully.
7437 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7439 * Added silc_server_save_channel_key into server.[ch] to save the
7440 received channel key in Channel Key payload processing. It is
7441 also used in JOIN command reply handling.
7443 Equivalent function silc_client_save_channel_key added into
7444 client.[ch] into client library.
7446 * Changed JOIN command reply to send information whether the channel
7447 was created or not (is existing already) and the channel key
7448 payload. Changed protocol specs accordingly.
7450 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
7451 the request was sent by ID and not by nickname. Crashed on
7454 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7456 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
7457 now correctly save the received data.
7459 * silc_server_free_sock_user_data now notifies routers in the
7460 network about entities leaving the network.
7462 At the same time implemented functions silc_server_remove_id
7463 and silc_server_send_remove_id to receive and send REMOVE_ID
7464 packets. The packet is used to notify routers in the network
7465 about leaving entities. The ID removed will become invalid in
7468 * Added function silc_idlist_del_server into server. Removes and
7469 free's server entry from ID list.
7471 * silc_server_private_message function now checks, if we are router,
7472 that the destination ID really is valid ID, naturally.
7474 * In router when NEW_ID packet is received (for new client) the
7475 hash of the Client ID is saved in the ID Cache but the
7476 client->nickname is set to NULL, instead of putting the hash
7479 IDENTIFY command now also checks that client->nickname must be
7480 valid. If it is not if will request the data from the server who
7481 owns the client. Added new function
7482 silc_server_command_identify_check.
7484 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
7485 to set the command to already allocated Command Payload.
7487 * Tested private message sending in router environment with two
7488 routers, two servers and two clients. Fixed minor bugs and now
7491 * Fixed segfault from client's NAMES command. Used to crash if
7494 * Forwarded packets must not be routed even if it is not destined
7495 to the receiver. Changed server code comply with this.
7497 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7499 * Added `require_reverse_mapping' boolean value to ServerParams
7500 structure. If TRUE (not default) the server will require that
7501 the connecting host has fully qualified domain name.
7503 If the reverse mapping is not required and hostname could not be
7504 found the IP address is used as hostname.
7506 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7508 * Implemented version string checking to both client and server.
7509 The check is incomplete currently due to the abnormal version
7510 strings used in development version of SILC.
7512 * Changed all command functions in server to use the new
7515 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7517 * Changed char *data to unsigned char *data in ID Cache system to
7518 support binary data as ID Cache data. Changed code to support
7519 binary data in lib/silccore/idcache.c.
7521 * Renamed silc_server_packet_relay_command_reply to
7522 silc_server_command_reply as it is normal packet receiving
7523 function. Rewrote the function to accept command replys for
7524 servers and not only for clients.
7526 * Mark remote router always as registered server if we are connecting
7527 to it. Otherwise, commands sent by the router to us are ignored.
7529 * All ID List find routines now returns the ID Cache Entry pointer
7530 as well if requested.
7532 * WHOIS command works now in router environment, tested with two
7533 routers, two servers and two clients.
7535 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
7536 in router environment (as it is almost equivalent to WHOIS) but
7537 hasn't been tested thoroughly. Added new functions:
7539 silc_server_command_identify_parse
7540 silc_server_command_identify_send_reply
7541 silc_server_command_identify_from_client
7542 silc_server_command_identify_from_server
7544 * Disabled route cache adding because adding two different ID's with
7545 same IP replaces the old cache entry thus giving wrong route.
7546 The entry->router->connection is always the fastest route anyway
7547 so route cache may not be needed. Of course, new routes maybe
7548 established after receiving the ID when the entry->router->connection
7549 might not be anymore the most optimal.
7551 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7553 * Add route cache for received ID for fast routing.
7555 * Added silc_server_packet_route to route received packet on router
7556 that is not destined to us.
7558 * Renamed silc_server_get_route to silc_server_route_get.
7560 * Added id_string and id_string_len fields into SilcServer to
7561 include encoded ServerID for fast comparing without excess
7562 encoding of the ID's.
7564 * Cleaned up WHOIS command on server side. Added following static
7567 silc_server_command_whois_parse
7568 silc_server_command_whois_check
7569 silc_server_command_whois_send_reply
7570 silc_server_command_whois_from_client
7571 silc_server_command_whois_from_server
7573 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
7574 arguments in command replies. All command functions should be
7575 updated to use this macro.
7577 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7579 * Minor typo fixes on command reply handling on server.
7581 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7583 * Added silc_server_command_add_to_channel internal routine to add
7584 the client to the channel after router has created the channel and
7585 sent command reply to the server.
7587 * Added generic silc_server_send_command to send any command from
7590 * Use static buffer with ID rendering instead of duplicating data.
7592 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7594 * Fixed a channel user mode bug when joining to a channel server gave
7595 everybody channel founder rights, oops.
7597 * We mark ourselves as the router of the incoming server connection
7598 if we are router ourselves. This way we can check in some packet
7599 sending functions whether it is locally connected server. For
7600 incoming router connections we put NULL.
7602 * For router sending packets locally means now always sending the
7603 packet cell wide; to local clients and local servers. For normal
7604 server sending packet locally means sending it to only local
7607 * Fixed the JOIN command to really work in router environment. If the
7608 channel is created it is always created by the router. Router is
7609 also responsible of making the initial joining to the channel,
7610 sending JOIN notify to the sending server and distributing
7611 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
7612 does not exist server doesn't do anything else but forward the
7613 command to the router which performs everything.
7615 * Added silc_server_send_channel_key function to send the Channel Key
7618 * Added silc_server_create_channel_key to create new channel key. The
7619 channel key is now re-generated everytime someone joins or leaves
7620 a channel, as protocol dictates. Note: channel->key_len is the
7623 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7625 * Splitted server.[ch] finally. Created now packet_send.[ch] and
7626 packet_receive.[ch] to separate packet sending and receiving
7627 routines. The server.[ch] now includes everything else including
7628 actual packet processing (writing and reading data) and other
7631 Renamed silc_server_private_message_send_internal to
7632 silc_server_send_private_message. The routine is still though
7633 used only to relay private messages as server does not send
7634 private messages itself.
7636 Renamed silc_server_new_channel to silc_server_create_new_channel
7637 and added new function sicl_server_new_channel that handles the
7638 incoming New Channel packet. Added also new sending function
7639 silc_server_send_new_channel to send New Channel Payload.
7641 * Added new function silc_server_notify to process incoming notify
7642 packet to the server/router. Server may then relay the notify
7643 to clients if needed.
7645 * Added new function silc_server_new_channel_user to process incoming
7646 New Channel User packet. Router will redistribute the packet and
7647 send JOIN notify to its local clients and locally connected servers
7648 if needed. Normal server will send JOIN notify to its local client
7649 on same channel when received this packet. Added also corresponding
7650 sending function silc_server_send_new_channel_user to sent the
7653 * Added boolean route argument to send_notif_to_channel and
7654 packet_send_to_channel functions to attempt to route the packet
7655 if it is TRUE and send only locally if it is FALSE.
7657 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7659 * silc_server_replace_id now broadcasts the received replace ID
7660 packet if it is not broadcast packet already. The router must
7661 broadcast to inform other routers about changed ID.
7663 * Added backpointer to server's router into SilcServer context in
7664 silcd/server_internal.h.
7666 * Fixed silc_server_packet_broadcast to send correct broadcast
7669 * The channel key is now distributed to the local client as soon
7670 as it is received from the router (in router environment) so that
7671 no other packet may be sent for the channel until client has
7674 * silc_server_remove_channel_user now broadcasts the received
7675 Remove Channel User packet if it is not broadcast packet already.
7676 The router must broadcast to inform other routers about removed
7679 * Added users field into SilcPacketContext that is a reference count
7680 of the context. One can increase the reference count by calling
7681 silc_packet_context_dup which is now changed to just increase the
7682 reference count instead of duplicating the data. The reference
7683 count is decresed by calling silc_packet_context_free that will
7684 free the data after the reference count hits zero.
7686 For now on the packet context and everything allocated into it
7687 (including the raw packet from network) must be freed by calling
7688 the new silc_packet_context_free function. Added also new function
7689 silc_packet_context_alloc that must be used now to allocate the
7690 context. This also means that if a routine is asynchronous from
7691 silc_[client/server]_packet_parse_type the packet context must
7692 be duplicated by calling silc_packet_context_dup. Otherwise it
7693 gets free'd after silc_[client/server]_packet_parse_type returns.
7694 Also, one must remember that if packet is duplicated then its
7695 reference count must be decresed by calling the free function as
7696 many times as it was duplicated.
7698 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7699 from both client and server.
7701 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7703 * Made joining to a channel working in router environment.
7705 * Cleaned up JOIN command on server side and create function
7706 silc_server_command_join_channel internal routine to make the
7709 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7711 * Changed silc_command_pending list to SilcDList. Also, added
7712 `ident' field to SilcServerCommandPending structure to identify
7713 the reply and to call correct callback.
7715 Added silc_server_command_pending_check function to replace the
7716 corresnponding macro. The silc_command_pending list is not
7719 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7720 to set identifier to previously allocated Command Payload. It
7721 is used to set identifier for command when resending Command
7724 * Added silc_command_payload_encode_payload to encode Command
7725 Payload buffer from SilcCommandPayload structure.
7727 * Added silc_argument_payload_encode_payload to encode Argument
7728 payload buffer from SilcArgumentPayload structure.
7730 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7732 * Changed WHOIS command to support router connection on server side.
7733 The whois request is always sent to router unless the server is
7734 standalone server. After server has received the reply from the
7735 router will it send the reply to the client.
7737 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7738 broadcast received broadcast packet. The function is used only
7739 by router. The broadcast packet is always sent to the router's
7742 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7743 render given ID to printable string, for log files for example.
7745 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7747 * Made basic router to router connections working. At least they
7748 can now connect to each other but nothing really works the way
7749 they are supposed - yet.
7751 * Added new initiator token to RouterConnection configuration
7752 file in silcd/serverconfig.[ch]. It is used to tell whether we
7753 are the initiator to the remote router or whether we'll expect
7754 the other end to connect.
7756 * Moved registering of listener task to silc_server_init, hence
7757 the server starts listenning as soon as it is run, even if it
7758 does not have connections to other routers. Let's see how well
7761 * Changed default connection retry timeouts for more suitable in
7764 * Removed cipher and such arguments from silc_idlist_add_client
7765 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7766 Added new function silc_idlist_add_data to add the keys and stuff
7769 * Added SilcIDListData structure and added it to SilcClientEntry
7770 and SilcServerEntry as their first field in the structure. This
7771 way we can explicitly cast the ID entries to the SilcIDListData
7772 structure and get common data for the entries. In past, we had
7773 to first check what type of connection it is and then cast it to
7774 correct ID entry type. Now, we can directly cast the opaque
7775 pointer to the SilcIDListData (no matter what ID entry it actually
7776 is) and get the data needed.
7778 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7780 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7781 in some circumstances even if threre were timeout tasks, though not
7782 IO tasks, but tasks anyway. Now fixed.
7784 * Defined SilcServerConnection structure to hold connection specific
7785 stuff about directly connected servers and routers. The definition
7786 is currently in silcd/server_internal.h. I thought about having
7787 a bit more important role fro this struct but for now it is used
7788 only when connecting to other server (or router actually).
7790 * Added connecting retry support in server when connecting to
7791 router(s). The retry feature implement exponential backoff
7792 algorithm. Also, added SilcServerParams structure to hold default
7793 parameters for server. For now, it include these retry settings
7794 and are hard coded. After server is moded to be as Silc Server
7795 Library this structure will be more important.
7797 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7799 * Changed client librarys channel->clients table to SilcList and
7800 changed code accordingly.
7802 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7804 * Changed client's channel table to SilcList and changed code
7805 accordingly. Also changed SilcChannelClientEntry to include back-
7806 pointer to the channel so that client entry can use that structure
7807 as list as well and we have fast cross-reference to the channel.
7808 This change dramatically decreased the complexity of channel
7809 handling with client entry and vice versa (removed one extra
7810 loop when searching for channel entry from many functions).
7812 * Changed server->sim from table to SilcDList and changed code
7815 * NAMES command can now be used from user interface. It will show
7816 the user list on the channel, neatly.
7818 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7819 Code now saves realname of the user if it becomes available.
7821 * Renamed configure.in to configure.in.pre and made ./prepare
7822 script to automatically add correct version string to
7823 configure.in which it creates from configure.in.pre.
7825 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7827 * NAMES command reply now shows users mode with the nickname when
7830 * Moved silc_client_ch[u]mode[_char] functions from
7831 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7832 place sucks, they are utility functions and should be in some
7835 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7837 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7840 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7844 * Added TRQ (efficient deque and list library) into lib/trq. This is
7845 a very good list library that is currently used in the SILC. Defined
7846 SilcList API over the library because I didn't like the API very
7847 much. See lib/trq/silclist.h for the API and examples of how to
7848 use the API. Fixed various places in the code to use the new
7849 SilcList API. The SilcList is meant for lists that has a structure
7850 already defined as a list. It is not suitable to add just some
7851 context to the list (in TRQ, the context is the list actually).
7853 So, I defined SilcDList that can be used for the purpose where
7854 predefined list structure does not exit. This can be used as
7855 such list. Now some context just can be added to the SilcDList.
7856 Currently this list is not used in the SILC just yet, though there
7857 are a lot places where this can replace dynamically allocated
7858 tables and I will fix these places, later, to use SilcDList.
7859 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7860 and use TRQ internally).
7862 Also fixed some annoying warning messages that the original TRQ
7863 code generated. Also minor changes to TRQ's Makefile.in.
7865 * Added support for querying by Client ID to both WHOIS and
7866 IDENTIFY commands into server, as required by the protocol.
7868 * Removed method function pointers from SilcBuffer structure. They
7869 weren't used to anything and just increased the context size for
7870 no good reason. This change also made silc_buffer_alloc and
7871 silc_buffer_free functions inline functions.
7873 * Disabled command flooding detection support until it's fixed so
7874 that it accepts commands in but does not execute them more than once
7877 * Added silc_net_localhost(), to return local hostname, into
7878 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7879 that must be initialized before calling silc_client_init.
7881 * Added new function: silc_server_send_notify_on_channels to send
7882 notify messages to all channels client has joined. It is assured
7883 that the message is sent only once per client.
7885 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7886 lib/silcutil/silcutil.[ch] as silc_format function. The new
7887 function is generic and is used by server as well, not only by
7888 the logging routines.
7890 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7891 the provided version string was not acceptable. Added new function:
7892 silc_ske_check_version into lib/silcske/silcske.h. The function
7893 must be implemented by the application (client or server) and it
7894 does not reside in the SKE library. The function checks the version
7895 string remote end sent.
7897 * Added back pointers (to opaque context and to SilcSocketConnection)
7898 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7900 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7901 duplicate packet context structure.
7903 * Changed `notify' client operation to send same arguments as client
7904 receives from server except for ID's. ID's are mapped to correct
7905 ID entry and that is returned. Also, if channel entry is not sent
7906 by server but the notify is for channel the channel entry is sent
7907 to application (otherwise application doesn't know that it is for
7908 channel (library gets it from packet's Destination ID)).
7910 * Added silc_client_remove_from_channels into client library to
7911 remove a client from all channels it has joined to. Used when
7912 received SIGNOFF notify from server. Added also new function
7913 silc_client_replace_from_channels to replace old ID entry with
7914 new ID entry on all channels. Used when received NICK_CHANGE
7917 * Fixed ID Cache list handling in silc_idlist_get_client in
7918 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7919 to get (or query) client by ID.
7921 * Updated TODO list.
7923 * Added connection authentication status message defined by the
7924 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7925 support for these into the code in client and server side.
7927 * Added generic function silc_client_send_command to send any command
7928 with variable argument list. Application should use this function
7929 to send commands if the command functions provided by the library
7930 does not suite for the application's user interface needs.
7932 * Added new `failure' client operation. Application is notified about
7933 received failure packet if client is executing a protocol. In this
7934 case the protocol's execution has failed.
7936 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7937 is required by the protocol.
7939 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7940 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7943 * Added status flag to SilcSKE object to indicate realtime status
7944 of the SKE protocol.
7946 * Application receives now exactly same command reply arguments as
7947 the library receives from server. However, if ID is received the
7948 corresponding ID entry is returned to the application (eg. Client
7949 ID is mapped to correct SilcClientEntry entry and that is returned).
7950 Changed command_reply client operation due to this change.
7952 * Changed all ID's in commands and in command replys as ID Payloads.
7953 Change affected both client and server side codes.
7955 All ID's sent in SILC network (with execption of ID's in SILC
7956 Packet header) are sent in ID Payload to support variable length
7959 * Server now notifies nick changes and notifies all clients on
7960 the channels about the new nickname (about the new Client ID,
7963 * Implemented CMODE command to change channel modes. Supports all
7964 channel modes defined by the protocol specs except ban and invite
7965 lists. (Also, private channel key mode is supported but support for
7966 setting private channel key in client is missing, thus, this mode
7967 has no effect on client side (except that server requires that the
7968 client uses private channel key and normal channel traffic does not
7971 Also, invite mode works per se, but INVITE command does not work
7972 yet correctly, so you can set channel as invite only channel but
7973 inviting clients to the channel does not work (it is yet to be
7974 thought what's the best way to do it).
7976 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7977 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7978 Implemented CUMODE command to change user's mode on the channel.
7979 Supports all modes defined by the protocol specs.
7981 * Added NAMES command reply to return users modes on the channel.
7983 * Removed unnecessary and slow ciphers from lib/silccrypt.
7985 * Set SO_KEEPALIVE option to connection sockets by default.
7987 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7989 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7990 redefined the Notify Payload into protocol specs.
7992 * Added silc_id_payload_parse_id to get ID directly from raw
7995 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7997 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7998 accept searching by Client ID as well.
8000 * Added support for LEAVE and SIGNOFF notify types in client library.
8002 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
8003 to parse ID Payload from raw data.
8005 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8007 * Added flags parameter into silc_ske_assemble_security_properties
8008 function in lib/silcske/silcske.[ch].
8010 * Changed notify client operation to fit better for notify messages
8011 sent by server. The notify payload received from server is now
8012 passed to the application (after parsing it to SilcNotifyPayload).
8013 It is application's responsibility to retrieve the arguments
8014 from the payload and show the message the way it wants. The message
8015 sent by server is implementation specific.
8017 * Changed public keys to comply with the protocol specification.
8018 Old public keys are not supported anymore and are not compatible.
8020 * Removed nickname from Channel Payload as the latest draft removed
8021 it. The client must resolve the nickname from the NAMES command
8022 reply received when it joined the channel.
8024 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
8026 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8028 * Fixed some errors in protocol specification drafts.
8030 * Created lib/silccore/silcnotify.c to implement Notify Payload
8031 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
8032 generic payloads described by protocol specifications. The file
8033 includes implementations for ID Payload and Argument Payload.
8035 * Changed Command Payload implementation to use the new Argument
8036 Payload. Changed command_xxxx_payload to command_payload_xxxx
8037 to comply with SILC coding conventions.
8039 * Added suppport for Argument Payload handling in Notify Payload
8040 implementation as protocol requires it. Added the new support
8041 into server and client lib as well.
8043 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8045 * Added support for multiple nicknames on same channel. [n] is
8046 added locally to the nickname if there are more than one same
8047 nicknames on the channel.
8049 * Server now sends all nicknames that matched WHOIS request.
8050 Client also shows the list received from server.
8052 * Added TOPIC command to client side. User can now set and show
8053 current topic on channel.
8055 * Added MOTD command to client and server. Also, server sends the
8056 motd when client connects to the server.
8058 * Changed version strings to comply ISO 8601.
8060 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8062 * Fixed protocol error handling in client library. It should now
8063 cope even if the SKE fails for some reason.
8065 * Made new protocol specification drafts for submitting to IETF.
8067 * Implemented TOPIC command to server in silcd/command.c.
8069 * Added two new notify types into lib/silccore/silcnotify.h:
8070 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
8071 notify nickname change and topic setting/change on a channel.
8073 * API change of command_reply operation in client library. The
8074 application gets now the status type received from server as well.
8076 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8078 * Removed the function just added to lib/silcutil/silcschedule.[ch].
8080 * Cras fixed and optimized the packet handling even further and
8081 it should work now. Minor change to the prototype of function
8082 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
8084 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8086 * Added new function into lib/silcutil/silcschedule.[ch]:
8087 silc_schedule_with_fd to select() a specified fd. The function
8088 returns after timeout expires or data arrives or goes. The
8089 function is used by packet routines to wait that all data is
8090 received from network.
8092 * Fixed data reading from network in lib/silccore/silcpacket.c.
8093 The code now assures that all data is read from the fd and then
8094 continues packet processing. This was a bug fix since the code
8095 used to drop some data in some circumstances.
8097 * Added new function into lib/silcclient/client.[ch]:
8098 silc_client_start_key_exchange to start key exchange after
8099 connection has been established to server. The code internally
8100 now uses this funtion but its main purpose was to provide it
8101 for applications that perform their own connecting. After
8102 application has created a connection it merely calls this
8103 function to start the key exchange between client and server.
8104 The library takes care of everything else after that.
8106 Updated also lib/silcclient/README to explain the usage of
8109 * Do not send to application information that connection has
8110 been established. Application gets notified it by connect
8113 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8115 * Applied cras's patch to add silc_schedule_one function. The
8116 function runs scheduler once and returns.
8118 * Fixed the scheduler after cras messed it up. The timeout
8119 handling works now as it's supposed to work.
8121 * Added into lib/silccore/ silcnotify.h to include notify
8122 message types support. Changed silc_server_send_notify*
8123 functions, in server.[ch], to support those new notify types.
8124 Added the support for the notify types into client library,
8125 as well. Added new notify client operation into ops.h in
8128 * Changed silc_server_packet_send_to_channel to send normal
8129 packets instead of just channel message packets. The function
8130 is now used to send the notify packets to channels. It is not
8131 used to send channel message packets anymore, as server never
8134 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
8135 va_arg()s as it seems to require it nowadays. I guess, if SILC
8136 is compiled with older va_arg() the new code should work anyway.
8138 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8140 * Splitted core library. Core library (lib/silccore) includes
8141 now only SILC protocol specific core (and common) components.
8142 Created new utility library (lib/silcutil) that includes more
8143 generic purpose stuff. The stuff for util library was taken
8144 from the old core library. This was minor and easy split.
8146 * Created SILC Client Library (lib/silcclient) that includes
8147 implementation of the SILC client without user interface. This
8148 was major move from silc/ directory. The code has been changed
8149 so that it is transparent towards the user interface. The
8150 silc/ directory includes now the same user interface as before
8151 and it uses the new client library. Read lib/silcclient/README.
8152 Basicly, the client library performs everything else related
8153 to SILC except user interface handling. Also, configuration
8154 files are considered to be part of user interface and library
8155 does not handle them.
8157 This change also changed a lot of structures, function naming etc.
8158 Most important change was that SilcClientWindow object was
8159 renamed to SilcClientConnection in the client library. Created
8160 also new file lib/silcclient/ops.h. Also added new files
8161 silc/local_command.[ch] and silc/client_ops.[ch].
8163 All these changes were made to make it easier for user interface
8164 designers to create what ever user interface for the SILC client
8167 It is also expected that the server will be moved to lib
8168 directory as well and SILC Server Library will be created;
8169 sometimes in the future.
8171 * Removed Local commands from lib/silccore/silccommand.h as
8172 they are application specific and new client library does not
8173 handle any of those anymore.
8175 * Several functions moved to lib/silcutil/silcutilc.[ch] from
8176 old client implementation in silc/.
8178 * Added support for callback functions in SILC_LOG_* macros.
8179 Application can now set its own callbacks that will be called
8180 instead of using the default functions that will always print
8181 the debug messages to stderr (or stdout). Also, debugging can
8182 now be disabled by setting silc_debug to FALSE and re-enabled by
8183 setting it to TRUE. Note, that logging will still work even
8184 if debugging is disabled.
8186 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
8187 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
8188 silc_log_reset_debug_callbacks.
8190 * To enable debugging in silc client one must give now -d
8191 option on command line.
8193 * Changed silc_schedule_init to automatically allocate task queues
8194 if they are not allocated before calling it.
8196 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8198 * Added GMP 3.1 into math library.
8200 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8202 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
8203 a channel in SILC network. The packet is used by servers and
8204 routers to notify other routers that user has left a channel.
8205 This little feature was missing until now. Added the feature
8206 to protocol specification as well.
8208 Added functions: silc_server_send_remove_channel_user and
8209 silc_server_remove_channel_user into server.[ch].
8211 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
8212 lib/silccore/silcpacket.h. However, they are not implemented
8215 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8217 * Fixed joining to a channel and sending channel messages
8218 between server and router. The channel message sending should
8219 now work inside a cell.
8221 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8223 * Fixed the private message sending between server and router.
8224 The private message sending should now work inside a cell.
8226 * Added silc_server_replace_id into server.[ch] to replace
8227 existing ID in the SILC network.
8229 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
8230 and silc_idlist_replace_server_id into idlist.[ch] in server.
8232 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8234 * Fixed the server to server connections. Server can again now
8235 connect to router. Router to router connections probably does
8238 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8240 * Added dynamic protocol registering support. Now protocols can
8241 registered and unregistered on the fly. Patch by cras.
8243 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8245 * Added lib/contrib directory to hold routines that some platforms
8246 don't have but are needed by SILC.
8248 * Added getopt.c, getopt1.c and getopt.h from GNU C library
8249 into lin/contrib to provide getopt() and getopt_long() for
8250 those who don't have it.
8252 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8254 * Added AWAY command to client. When away message is set and
8255 client receives a private message packet the client automatically
8256 replies to the sender with the away message.
8258 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
8259 bug seemed to be the cause of recent problems when compiling
8262 * Added version detection support to SKE protocol specification
8263 and added the new changes to the SKE implementation as well.
8264 There were other minor changes in the SKE protocol as well.
8266 Many changes in lib/silcske/silcske.[ch] and in
8267 lib/silcske/payload.[ch].
8269 * Added ^U functionality, clear input line. Patch from cras.
8271 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8273 * Mainly small bugfixes on core library. Fixed some debugging
8274 logging and buffer overflow in silclog.c.
8276 * Updated config.sub and config.guess on the distribution tree.
8278 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8280 * Added command lagging support in server. Client may execute
8281 commands now only once in two seconds.
8283 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8285 * Optimized packet reception. MAC computation and checking is now
8286 also more optimized. A lot previously duplicated code is now
8287 used as generic by both client and server.
8289 * Fixed key pair generation in clientutil.c
8291 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8293 * Added into lib/silccore/silcbufutil.[ch] new function;
8294 silc_buffer_realloc.
8296 * Moved generic packet sending/encryption functions to
8297 lib/silccore/silcpacket.[ch] from client and server. Some
8298 rewriting of the functions.
8300 * Moved all generic packet reception/decryption functions to
8301 lib/silccore/silcpacket.[ch] from client and server. The
8302 packet processing is now much cleaner in both client and server.
8303 These were major changes in both client and server.
8305 * Created many common functions in server to do packet sending.
8306 Previously code were duplicated a lot, this has been removed
8309 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8311 * Rewrote major parts of the ID cache system. Don't know
8312 whether it is better now or not but at least the API is more
8315 * Major rewrite on ID cache stuff on client because of the ID
8316 cache API changes. Added idlist.c to client.
8318 * Also major rewrite on ID cache stuff on server as well.
8319 Major rewrite of idlist.[ch]. SilcXXXList's are now named
8320 SilcXXXEntry's. We won't keep anymore idlist specific pointers
8321 in hand, instead they are all put into the ID cache system now.
8322 All server_idlist_* routines uses ID cache now instead of
8323 traversing its own lists (those lists does not exist anymore).
8324 SilcIDList though still exists. Also, SilcXXXEntry's are
8327 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8329 * Finally made the SKE implementation compliant to the protocol
8330 specification. All mp integers are now binary encoded as
8331 opposed being HEX encoded.
8333 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
8336 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
8337 functions: silc_[encode/decode]_pem. Also added function
8338 silc_encode_pem_file to PEM encode with newlines ('\n') for
8341 * SILC public keys are now encoded either PEM or binary. Same
8342 option is for private keys as well. By default private keys
8343 are binary encoded and public keys PEM encoded. Silly HEX
8344 encoding were removed.
8346 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
8347 function to create fingerprints.
8349 * Fixed a bug in SHA1; does not change the original data anymore.
8351 * Partly implemented INFO command on client and server side.
8352 Fixed CLEAR command. Changes to SERVER command; show current
8353 server(s) when giving command without arguments. Added
8354 VERSION command to client.
8356 * Added check to server that unregistered connections cannot
8357 execute commands (unless it is specificly allowed).
8359 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8361 * Fixed screen refresh.
8363 * Fixed channel joining bug from client. On some circumstances
8364 client tried to join to a channel it had already joined.
8366 * Added public key verification process into client's protocol.c.
8367 The client now verifies the public key from user and saves
8368 it into ~./silc/serverkeys/ directory.
8370 Added into: clientutil.[ch]: silc_client_verify_server_key.
8372 * Changed SKE protocol's silc_ske_initiator_finish function
8373 to accept callback function that verifies the received public
8374 key. Removed old silc_ske_verify_public_key function.
8376 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8378 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
8379 silc_pkcs_private_key[_data]_set.
8381 * Made the password and public authentication more cleaner in
8382 server's protocol.c.
8384 * Removed historic and obsolete protocol `channel_auth' from
8385 both client and server.
8387 * Removed wrong way of sending command status messages from
8388 server to client in server's command.c. The old way violated
8389 protocol specification.
8391 Changes to silccore/silccommand.[ch]: removed
8392 silc_command_encode_status_payload -> not needed anymore,
8393 changed silc_command_encode_payload_va to accept extra
8394 argument on variable argument list. The argument type must
8395 now be provided to the function. Also, added new function:
8396 silc_command_encode_reply_payload_va which is same as
8397 normal command_encode_payload_va except command status type
8398 is provided as extra argument.
8400 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8402 * Added ~./silc directory handling. The directory includes the
8403 public and private keys for the client.
8405 Added silc_client_check_silc_dir, silc_client_create_identifier
8406 and silc_client_load_keys.
8408 * Implemented SILC protocol compliant public key. Added public
8409 and private key saving to and loading from files.
8411 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
8412 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
8413 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
8414 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
8415 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
8417 Implemented: silc_pkcs_save_[public/private]_key[_data] and
8418 silc_pkcs_load_[public/private]_key.
8420 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8422 * Added silc_server_get_route (route.[ch]) to get connection
8423 data for the fastest route for given ID.
8425 * Implemented INVITE command on client and server. The command
8426 were re-defined in the SILC Protocol Specification and the
8427 implementation now complies with the specification.
8429 * Implemented PING command on client and server.
8431 * Implemented NAMES command on client and server. The server side
8432 supports currently only normal server not router server yet.
8433 Some changes to NAMES definition in SILC protocol specification.
8435 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8437 * Implemented LEAVE command on client and server.
8439 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
8440 again. This change was made to the protocol as well. Server
8441 should not violate the protocol specification anymore.
8443 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8445 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
8446 was tested. SOCKS4 was not but should work anyway.
