512 lib/silccore/silcchannel.h.
514 Changed the client library to return the message length
515 to application as well in the channel_message and private_message
516 client operations. Affected files are
517 lib/silcclient/client_prvmsg, lib/silcclient/client_channel.c,
518 lib/silcclient/silcclient.h, irssi/src/silc/core/client_ops.c,
519 and lib/silcclient/client_ops_example.c.
521 * Added two new channel modes: SILC_CMODE_SILENCE_USERS
522 and SILC_CMODE_SILENCE_OPERS which can be used to moderate
523 the channel. Updated protocol specs and impelemented this
524 to client and server. Protocol TODO #6. Affected files are
525 silcd/packet_receive.c, server_util.c, lib/silcclient/command.c,
526 lib/silcclient/client_channel.c, lib/silccore/silcmode.h.
528 Added new options m and M to CMODE command in Irssi SILC
529 client to set these modes.
531 * Deprecated all administrative commands from SILC protocol
532 since they are highly implementation specific commands.
533 Updated protocol specs. Moved the old commands in
534 implementations to private range of command types. Affected
535 files are silcd/command.c, lib/silcclient/command.c and
536 lib/silcclient/command_reply.c. Protocol TODO #8.
538 * Fixed a bug in server where sending unknown command crashes
539 the server. Affected file silcd/command.c.
541 Wed Apr 3 09:57:47 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
543 * Added SILC_PROTOCOLVERSION macro to check protocol version
544 of a socket connection. The affected file is
545 lib/silcutil/silcsockconn.h.
547 * Added better error logging in rekey protocol. Affected file
550 * Do not check public key types in SKE during rekey. Affected
551 file lib/silcske/payload.c.
553 * Fixed the rekey protocol with PFS, which was totally broken.
554 Affected file silcd/protocol.c.
556 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
558 * Some client implementations quit network by doing first LEAVE
559 and then immediately SIGNOFF (like Bombyx). We now do check
560 after a short time after LEAVE notify and check whether the
561 client is still valid after LEAVE, and if not we remove it from
562 cache. Affected file is lib/silcclient/client_notify.c.
564 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
566 * Merged version 1.1.4 of zlib. Even if it not currently in use,
567 it's good not to have security holes here.
569 * Fixed a negative refcount situtuation for the config context.
570 Affected file is silcd/serverconfig.c.
572 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
574 * ROBOdoc documented lib/silcutil/silcutil.h.
576 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
578 * Optimized even more the SilcPacketContext structure. Now
579 totally saved 16 bytes of memory per context after optimization.
580 Affected files are lib/silccore/silcpacket.[ch].
582 * Made strict checks for valid SILC IDs. Affected file is
583 lib/silccore/silcid.c.
585 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
587 * Changed the object argument for silc_cipher_register,
588 silc_hash_register, silc_hmac_register and silc_pkcs_register
589 to const. Affected files are lib/silccrypt/silccipher.[ch],
590 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
592 * Changed the silc_get_username and silc_get_real_name to
593 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
595 * Fixed the Irssi SILC Client to use the silc_get_username and
596 silc_get_real_name insted of glib routines since the glib
597 routines only corrupt stack. Fixes the Irssi SILC to work in
598 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
600 * Fixed the Irssi to not use g_get_home_dir since it crashes
601 or returns garbage on cygwin and corrupts stack. Added function
602 get_home_dir to Irssi routines. Affected files are
603 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
605 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
607 * Made some structure optimizations. SFTP memory FS MemFSEntry
608 entry structure. Optimized SilcTask structure. Optimized
609 SilcPacketContext structure.
611 Affected files lib/silcsftp/sftp_fs_memory.c,
612 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
614 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
616 * And yet again reverted back the config thing since Johnny
617 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
620 * Fixed memory leaks from config object. Affected files are
621 silcd/serverconfig.[ch].
623 * Added support for adding new connections to the server in rehash.
624 After rehash they take effect.
626 Added support for changing the maximum allowed connections in
627 rehash. The number can grow but going smaller is not supported.
629 Added function silc_server_num_sockets_by_remote to the
630 silcd/server_util.[ch].
632 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
634 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
636 * Added preliminary checking during config parsing for a valid
637 public/private key and removed further checks in the code.
638 Affected files are silcd/serverconfig.[ch], server.c.
640 * Moved functions silc_server_drop() and silc_server_daemonise()
641 from server.c to silcd.c since they are stricly related to
642 the application activity.
644 * Reverted a small part of the automatic ref/unref since
645 it caused a double unref in some situations. Affected
646 files are silcd/silcd.[ch], server.c, serverconfig.c.
648 * Added some .cvsignore files in the lib directory.
650 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
652 * Fixed silc_net_gethostbyaddr to correctly resolve by
653 address. Affected file lib/silcutil/silcnet.c.
655 * Fixed the notify relaying to client. The HMAC to be used
656 with relayed packets ws wrong and caused decryption failure
657 at the client end. Affected file is silcd/packet_receive.c.
659 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
661 * Created new branch silc_protocol_1_0_branch.
663 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
665 * Changed the silc_server_config_* routines to be SilcServer
666 independent. They are now officially application specific code
667 and not part of generic server implementation. Affected files
668 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
670 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
672 * Added automatic referencing of config context in the
673 silc_server_config_alloc, and automatic unreferencing in the
674 silc_server_config_destroy. Affected files are
675 silcd/serverconfig.[ch], silcd/silcd.c.
677 * Fixed the silc_log_quick handling in the logging routines.
678 It didn't log quickly when it was TRUE. Affected file is
679 lib/silcutil/silclog.c. Also the flush delay was set even
680 if it was 0 in config file. Affected file is
681 silcd/serverconfig.c.
683 * Added support for changing key pair of the server in rehash.
684 Affected file silcd/server.c.
686 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
688 * Fixed the TOPIC_SET notify to not cras. It changed the topic
689 too early, before getting the channel entry. Affected file
690 is silcd/packet_receive.c.
692 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
694 * Added functions silc_server_config_[ref/unref], these are used
695 to prevent that the config object is destroyed.
697 No longer directly affect global variables silc_log_quick and
698 silc_log_delay, they are first cached inside the config object
699 and then applied with silc_server_config_setlogfiles().
701 silc_server_config_set_defaults() is now internal to
702 serverconfig.c, there are no reasons to show this internal stuff
705 Affected files are silcd/serverconfig.[ch].
707 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
708 fprintf's to stderr, since some code may be executed again after
709 the server went into the background. Affected files are
712 * Added rehash support. Added function silc_server_rehash() that
713 will perform all the basic tasks of the rehashing procedure.
715 * Added command line option `-x, --hexdump'. This will enable the
716 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
717 The option `--hexdump' implies `--debug'.
719 * Fixed a bad bug in the logging APIs (silcutil library) where
720 the application would crash after calling silc_log_reset_all().
722 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
724 * Fixed the KICKED notify handling in client library to
725 correctly remove the channel and all entries from the
726 channel when I was kicked. This bug crashed the client.
728 Fixed yet another but in KICKED notify handling to remove
729 the kicked client correctly from the channel.
731 Affected file is lib/silcclient/client_notify.c.
733 * Fixed a minor bug in looking up correct client entry
734 in KICKED notify in server. Affected file is
735 silcd/packet_receive.c.
737 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
738 sources correctly to distribution. Fixes --with-gmp option.
740 * Removed the manual rehashing from ID Cache, and changed it
741 to use the SILC Hash Table's auto rehash feature. Affected
742 file is lib/silccore/silcidcache.c.
744 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
746 * Fixed a bug in the silc_client_nickname_format function that
747 handles the multiple same nickname formatting. Two clients
748 with same nickname caused problems after the first one left
749 and rejoined. It didn't format the nickname correctly.
750 Affected file is lib/silcclient/idlist.c.
752 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
754 * Don't change the topic if olod topic is same as new one.
755 Affected file is silcd/packet_receive.c.
757 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
759 * Added cross-reference support to the SILC Documentation
760 generator. All types across all HTML files are now cross-
761 referenced. Affected files util/robodoc/generator.c and
762 scripts/silcdoc/silcdoc.
764 * Added file lib/silcutil/silctypes.h to include all the
765 arithmetic type definitions and some macros. Removed
766 includes/bitmove.h and moved macros to silctypes.h.
768 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
770 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
772 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
774 * Added `type' argument to silc_id_payload_parse_id function which
775 now returns the type of the ID to the sent pointer. Affected
776 file is lib/silccore/silcid.[ch].
778 * Added check for CMODE_CHANGE notify type that mode change is
779 allowed by the sender. Affected file silcd/packet_receive.c.
781 * Added check for CUMODE_CHANGE notify type that mode change is
782 allowed by the sender. Affected file silcd/packet_receive.c.
783 Added the ID type as CUMODE_CHANGE notify type as argument
784 to the `notify' client operation. Affected files are
785 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
787 * Added function silc_client_add_server to the client library.
788 Added support for resolving also channel and server info when
789 received unknown entity in notify packet. Affected files are
790 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
792 * Added function silc_command_get_status to return the command
793 status from the command reply's argument payload. Affected files
794 are lib/silccore/silccommand.[ch].
796 * Added check for KICKED notify type that the kicking is
797 allowed by the client. Affected file silcd/packet_receive.c.
799 * Created function silc_get_input which can be used to get input
800 (echo on or off) from user on command line. Affected files are
801 lib/silcutil/silcutil.[ch].
803 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
805 * Optimized silc_server_packet_relay_to_channel function.
806 Added new function silc_channel_message_payload_encrypt which
807 can be called directly if channel message payload needs to
808 be encrypted and is already encoded (no need to call _encode
809 function). Packet relaying is now done by router without any
810 extra memory allocations. Affected files are
811 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
814 * Fixed the INVITE notify handling. It took wrong arguments
815 as invite list and invite delete. Affected file is
816 silcd/packet_receive.c.
818 * Added check for TOPIC_SET notify type that the topic change is
819 allowed by the client. Affected file silcd/packet_receive.c.
821 * Added check for INVITE notify type that inviting is allowed by
822 the client. Affected file silcd/packet_receive.c.
824 * Changed the silc_server_client_on_channel to return the
825 SilcChannelClientEntry as well. Moved the function
826 silc_server_check_cmode_rights to server_util.[ch].
827 Affected files are silcd/server_util.[ch], silcd/command.c.
829 * Added function silc_server_check_umode_rights to check whether
830 changing client's user mode is allowed. Added check for
831 UMODE_CHANGE notify type that the umode change is allowed
832 by the client. Affected files are silcd/server_util.[ch],
833 silcd/packet_receive.c and silcd/command.c.
835 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
837 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
838 ID length. It ignored that ID can be IPv6 based as well.
839 Affected file lib/silccore/silcpacket.h.
841 * Fixed the silc_id_id2str and silc_id_str2id to take the
842 IPv6 address offset's into consideration. Affecte file is
843 lib/silccore/silcid.c.
845 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
847 * Fixed the internal Unix scheduler functions to check for
848 NULL context they may receive. The affected file is
849 lib/silcutil/unix/silcunixschedule.c.
851 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
853 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
854 can specify different directory with --home command line
855 parameter. Affected files irssi/src/silc/core/client_ops.c,
858 * SILC-specific commands aren't now executed if the active server
859 isn't of SILC-type, so there won't be problems with having
860 IRC and SILC protocol support in same client. Affected files
861 irssi/src/silc/core/silc-channels.c, silc-servers.c,
864 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
866 * Improved the signal support in SILC Schedule. Added new
867 function silc_schedule_signal_call which is used by application
868 to mark a signal to be called. It is now safe to perform
869 any kind of tasks in signal callbacks since it is guaranteed
870 that the application specified signal callback is called
871 after the signal is over. Affected files are
872 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
874 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
876 * Added `name' field to SilcChannelPrivateKey to represent
877 application given name for the key. Moved also the context from
878 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
879 Added the `name' argument also to the function
880 silc_client_add_channel_private_key.
882 Added function silc_client_current_channel_private_key to set the
883 current channel private key in use.
885 Added "change" command to KEY command which can be used to change
886 the current channel private key. Bound the command also to
889 Also affected files lib/silcclient/client_channel.c,
890 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
892 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
894 * Added silc_rng_get_byte_fast function in to the
895 lib/silccrypt/silcrng.[ch].
897 * Changed the interface of silc_packet_assemble and the
898 silc_packet_send_prepare. If silc_packet_assmble is now
899 called the application does not call silc_packet_send_prepare
900 because the library will call it automatically. These
901 interfaces now also return a reference to the outgoing buffer
902 which includes the assembled packet, which the application can
903 use to encrypt the packet.
905 Affected files are lib/silccore/silcpacket.[ch],
906 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
907 silcd/packet_send.c, server_backup.c and packet_receive.c.
909 * Fixed a packet sending bug on very high load, where outgoing
910 packet queue wasn't handled correctly and packets got corrupted.
911 Affected files are lib/silcutil/*/silc*sockconn.c,
912 lib/silcclient/client.c and silcd/server.c.
914 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
916 * Added macro SILC_PACKET_DATALEN which can be used during
917 packet assembling to check whether the data to be added to
918 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
919 len is truncated until it fits it.
921 Added checks for maximum length of channel message payload and
922 private message payload also.
924 Added checks for maximum packet length in server and in
927 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
928 lib/silcclient/client.c, lib/silccore/silcchannel.c and
929 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
930 lib/silcclient/client_prvmsg.c.
932 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
934 * Added silc_server_packet_queue_purge call to the
935 silc_server_disconnect_remote to assure that all data in the
936 queue before disconnecting is sent to the network. Affected
939 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
941 * Added the deleting of server's own ID cache entry to the
942 silc_server_free function. Free also everything else that
943 has been allocated in silc_server_init. The affected file
946 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
948 * Added functions silc_parse_version_string, silc_version_to_num,
949 and silc_ske_parse_version to parse SILC protocol style version
950 strings. Affected files lib/silcutil/silcutil.[ch] and
951 lib/silcske/silcske.[ch].
953 * Added new configuration params: version_protocol, version_software
954 and version_software_vendor to specify what version the remote
955 host must at least be to be able to connect to server. The vendor
956 string can be regex matched too. Added new function
957 silc_server_connection_allowed to check maximum number of allowed
958 connections, and allowed versions for incoming connections.
959 Affected files are silcd/server.c, server_util.[ch] and
962 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
964 * Added preliminary support for signals in scheduler. The
965 signals we care about are now blocked always when the scheduler
966 is locked. This way we can synchronise the use of signal with
967 scheduler. It is guaranteed that when signal occurs the scheduler
968 is not locked, and thus new tasks can be safely added to the
971 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
972 to silc_schedule_internal_init and silc_schedule_internal_uninit.
973 Added new platform specific routines
974 silc_schedule_internal_signals_[un]block and
975 silc_schedule_internal_signal_[un]register.
977 Added new functions to SILC Schedule API:
978 silc_schedule_signal_[un]register. Each signal that application
979 is going to use should be registered to the scheduler.
981 Affected files are lib/silcutil/silcschedule.[ch],
982 lib/silcutil/*/silc*schedule.c.
984 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
986 * Check for unauthenticated client and server in the
987 silc_server_new_client and silc_server_new_server functions.
988 Affected file silcd/packet_receive.c.
990 * Added function silc_string_is_ascii to check whether given
991 string is 7-bit ASCII string. Affected files are
992 lib/silcutil/silcutil.[ch].
994 * Added function silc_id_is_valid_server_id into the
995 silcd/serverid.c and added checking for valid Server ID's in
996 silc_server_new_server. The Server ID must always be based
997 on the server's public IP address.
999 * Added logging of DISCONNECT packet message in the server.
1000 Affected file silcd/server.c.
1002 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1004 * Changed all library interfaces that use Global RNG to also
1005 accept SilcRng as argument. Affected files are
1006 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
1007 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
1008 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
1009 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
1010 lib/silccrypt/rsa.c.
1012 * Added function silc_pkcs_generate_key to the
1013 lib/silccrypt/silcpkcs.[ch] for applications so that they
1014 don't need to do pkcs->pkcs->init calls anymore.
1016 * Remove SilcSocketConnection from the SFTP API since it really
1017 wasn't needed there. The application has the information
1018 saved in its contexts anyway and the SFTP layer doesn't need
1019 know about it. Affected files lib/silcsft/silcsftp.h and
1020 lib/silcsftp/sftp_[server/client].c.
1022 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
1023 The SilcSimContext is not SilcSim.
1025 * Fixed possible buffer overflows in silc_id_render in the
1026 lib/silcutil/silcutil.c.
1028 * On EPOC the global crypto module lists are not used at all
1029 in the crypto library. Added support for using the constant
1030 algorithm list on EPOC. Affected files are
1031 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
1034 * Fixed the handling of third parameter of KICKED notify, since
1035 it was mistakenly updated to SILC Protocol 1.0 even though it
1036 is to be included in 1.1. Since it is not in 1.0 it is not
1037 mandatory, and this fix now handles it only if it is provided,
1038 and it is not error if it is not provided. Affected file
1039 lib/silcclient/client_notify.c.
1041 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1076 functions to be used with SilcHashTable. They can be used to
1077 hash public keys and compare public keys in hash table. Affected
1078 file lib/silcutil/silcutil.[ch].
1080 * Added support for specifying multiple public keys for Client
1081 connection section in server configuration file. This makes it
1082 possible to accept multiple public keys from same host, or to
1083 make a section that accepts any incoming host, and have the
1084 accepted public keys listed in the section.
1086 Added functions silc_sever_[find/get]_public_key, added the
1087 support for this actually to all connection sections but only
1088 the Client section is currently allowed to specify multiple
1091 Affected files are silcd/server.c, server_internal.h,
1092 command.c, protocol.c, server_util.[ch], packet_receive.c.

1106 Affected files are lib/silcutil/silclog.[ch].
1108 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1110 * Fixed the server to check correctly the amount of connections
1111 from single host, by checking also the type of the connection.
1112 Fixed also the comparison of number of connections and number
1113 of allowed connections. Affected files are silcd/server.c,
1116 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1195 application does not need to define them. Affected file
1196 includes/silcincludes.h.
1198 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
1199 old name went against naming convention. Applications now
1200 include "silcclient.h" instead of "clientlibincludes.h".
1201 Removed includes/clientlibincludes.h, it is redundant now.
1203 * Renamed includes/version.h to silcversion.h.
1205 * Added really preliminary support for OS/2 into the util
1206 library. Only thread & mutex API is implemented, others
1207 are still to be implemented. Created the lib/silcutil/os2/
1208 directory. Created also file includes/silcos2.h.
1210 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1241 * Added `user_count' to the SilcChannelEntry which now tells the
1242 number of users on the channel. The user count is now saved
1243 in normal server of global channels as well. Affected files
1244 silcd/server.c, idlist.h, packet_receive.c and command.c.
1246 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
1247 include file utility functions.
1249 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
1250 instead of calling directly OS routines.
1252 * Fixed NICK change printing in Irssi SILC Client. Fixed
1253 KICKED notify printing in Irssi SILC Client. Affected file
1254 irssi/src/silc/core/client_ops.c.

1260 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1262 * ROBOdoc documented the lib/silcske/silcske.h, and improved
1263 the SKE interface a bit.
1265 * Fixed padding problem in PKCS#1. The padding was not actually
1266 random since the random number generator was used incorrectly.
1267 This security bug affects only when encrypting with PKCS#1, and
1268 it is not currently used at all in SILC. SILC only use signing
1269 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
1271 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1329 is now done in silc_core_init() which also fixes autoconnecting
1332 Affected files irssi/src/silc/core/silc-core.c,
1333 irssi/src/fe-text/silc.c.
1335 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1337 * Added new configuration options and blocks:
1338 keepalive_secs, reconnect_count, reconnect_interval,
1339 reconnect_interval_max, reconnect_keep_trying and
1340 require_reverser_lookup. Added ConnectionParam block, and
1341 implemented the connection parameters when connecting as
1342 initiator and when accepting connections as responder.

1350 algorithm parts and created new file silcalgs.conf, that
1351 is now included from the example_silcd.conf.in.
1353 * Optimized the silc_server_connect_to_router_second to take
1354 the connection configuration object from the SilcServerConnection
1355 object instead of finding it during the connecting phase.
1356 Added the configuration object to SilcServerConnection struct.
1357 Affected files silcd/server_internal.h, server.c.
1359 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1361 * Add the client on channel after it was resolved at the
1362 channel message receiving, and it was not already on the
1363 channel. Affected file lib/silcclient/client_channel.c.
1365 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1381 authentication to be set at the same time.
1383 Added `prefer_passphrase_auth' setting in config file which
1384 can be used to set to prefer passwd auth if both passwd and
1385 public key is set. If not set, public key is preferred.
1386 This has effect only when being initiator (responder will try
1389 Added support for authentication with passphrase and public key
1390 at the same time. The passphrase is tried first always since
1391 it is faster to check.
1393 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
1395 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

1425 as header filenames.
1427 * Removed lib/silcclient/README and created HTML file
1428 lib/silcclient/silcclient_using.html, which is now included
1429 as part of Toolkit documentation.
1431 Thu Feb 7 10:12:25 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1433 * Fixed CUMODE_CHANGE notify handling to change the mode of
1434 correct client. Affected file lib/silcclient/client_notify.c.

1441 * Fixed the file transfer's key agreement payload to include
1442 zero port also if the hostname is NULL because it could not
1445 Call file transfer monitor callback now also if error occurs
1446 during key agreement protocol.
1448 Changed the silc_client_file_send interface to return the
1449 SilcClientFileError instead of session id. The session ID
1450 is returned into pointer provided as argument.

1467 file lib/silcutil/silclog.c.
1469 * Fixed the channel message payload decryption in the function
1470 silc_channel_message_payload_decrypt to not modify the original
1471 buffer before it is verified that the message decrypted
1472 correctly. Otherwise, next time it is called with correct
1473 channel key it won't encrypt since the payload is corrupted.
1474 Affected file lib/silccore/silcchannel.c.
1476 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1488 * Fixed a bug in hash table internal routine for traversing
1489 the table with foreach callback. The current entry may
1490 become invalid in the callback but it was referenced after
1491 the callback returned.
1493 Do not allow auto rehashing of hash table during the
1494 silc_hash_table_foreach operation, for same reasons as it is
1495 not allowed for SilcHashTableList. Affected files are
1496 lib/silcutil/silchashtable.[ch].
1498 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>

1508 lib/silcclient/client_prvmsg.c.
1510 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1512 * Added function silc_client_add_channel,
1513 silc_client_replace_channel_id, and removed functions
1514 silc_client_new_channel_id and silc_idlist_get_channel_by_id
1515 from client library.
1517 * Added cross reference of the joined channels to the
1518 SilcClientEntry, and changed the SilcChannelEntry's
1519 users list to SilcHashTable. The affected files are
1520 lib/silcclient/idlist.[ch].
1522 * Fixed a bug in hash table tarversing. While the hash table
1523 is traversed with SilcHashTableList the table must not be
1524 rehashed. It is now guaranteed that auto rehashable tables
1525 are not rehashed while tarversing the list. Also defined that
1526 silc_hash_table_rehash must not be called while tarversing
1527 the table. Added function silc_hash_table_list_reset that must
1528 be called after the tarversing is over. The affected files are
1529 lib/silcutil/silchashtable.[ch].
1531 * Changed all hash table traversing to call the new
1532 silc_hash_table_list_reset in server and in client library.
1534 * Added function silc_client_on_channel to return the
1535 SilcChannelUser entry if the specified client entry is joined
1536 on the specified channel. This is exported to application as
1537 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
1539 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1545 * Fixed the WHOWAS command's reply sending to support the
1546 lists correctly. Affected file silcd/command.c.
1548 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1550 * When sending JOIN command to router for processing the
1551 sender's old command identifier was not saved back to the
1552 sender's command context, fixed now. The affected file is
1555 * Create the key in JOIN command of the router did not return
1556 the channel key, added check for this. Affected file is
1559 * Fixed a channel ID update bug in JOIN command reply. Do
1560 not directly upgrade the ID but call the function
1561 silc_idlist_replace_channel_id if the ID was changed.
1562 Affected file silcd/command_reply.c.
1564 * Fixed memory leaks from command calling if it would fail.
1565 Affected file silcd/command.c.
1567 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1569 * Applied patches from cras:
1571 Memory leak fixes around libaries, irssi window resize fix,
1572 new silclist.h and silcdlist.h, all extern inline changed to
1575 * Removed dotconf from lib/dotconf, not needed anymore.
1577 * Removed TRQ from lib/trq, not needed anymore.
1579 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
1580 with server connections. Later this will be configurable
1581 in config file after new config file is done. Affected file
1584 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1586 * Fixed a crash in server related to channel announcements.
1587 Affected file silcd/server.c.
1589 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1591 * Fixed memory leaks in silc_server_create_new_channel*
1592 functions. Affected file silcd/server.c.
1594 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
1595 which ID was changed. This way the router will send the
1596 user list for the channel again, and server won't be in
1597 desync in some rare circumstances. Affected file is
1598 silcd/packet_receive.c.
1600 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1602 * Check for NULL socket pointer in the function
1603 silc_server_packet_send_to_channel_real. Affected file
1604 silcd/packet_send.c.
1606 * Fixed the BAN notify handling to correctly remove ban
1607 list. Affected file silcd/packet_receive.c.
1609 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1611 * Fixed some header addition to Toolkit distribution in
1612 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
1614 * Added lib/silcclient/client_ops_example.h as an template
1615 file for application programmers to quickly start using
1616 the SilcClientOperation functions in their application.
1617 Updated the lib/silcclient/README as well to tell about this
1618 nice file made available.
1620 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1622 * Call silc_server_remove_from_channels when removing client
1623 entry when NO_SUCH_CLIENT_ID was received. Affected file
1624 is silcd/command_reply.c.
1626 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1628 * Added server & router operator statistics updating. Affected
1629 file silcd/packet_receive.c and silcd/command.c.
1631 * Fixed the SERVER_SIGNOFF notify handling on normal server
1632 not to save the history information for clients. Same was
1633 fixed earlier in remove_clients_by_server function, but not
1634 here. Affected file silcd/packet_receive.c.
1636 * Raised the default connection-retry count from 4 to 7 in
1637 server. Affected file silcd/server.h.
1639 * Cancel any possible reconnect timeouts when we start the
1640 key exchange. Affected file silcd/server.c.
1642 * Do not reconnect on connection failure when SCONNECT was
1643 given. Affected files silcd/server.[ch].
1645 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1647 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
1649 * Fixed the NICK command to always give the unformatted
1650 nickname to the one giving the NICK command. If unformatted
1651 nickname is cached already it will be formatted and the
1652 local entry will always get the unformatted nickname.
1653 Affected file lib/silcclient/idlist.c.
1655 * Fixed some double frees from client library commands.
1656 Affected file is lib/silcclient/command.c.
1658 * Fixed CUMODE command in server to assure that no one can
1659 change founder's mode than the founder itself, there was a
1660 little bug. Affected file silcd/command.c.
1662 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1664 * Removed the SilcClientCommandDestructor from the client
1665 libary, it is not needed anymore. Affected files are
1666 lib/silcclient/silcapi.h, command[_reply].[ch],
1667 client_notify, idlist.c.
1669 * Fixed GETKEY command to first resolve client, and then
1670 resolve the server only if the client was not found, instead
1671 of resolving both at the same time. Affected file is
1672 lib/silcclient/command.c.
1674 * Added silc_client_start_key_exchange_cb and lookup the
1675 remote hostname and IP address before starting the key
1676 exchange with server. The affected file is
1677 lib/silcclient/client.c.
1679 * The server's public key is now saved using the IP address
1680 of the server and not the servername for the filename.
1681 The hostname public key filename is checked as an fall back
1682 method if the IP address based filename is not found.
1684 Fixed the GETKEY command to save the fetched server key
1685 in correct filename.
1687 Print the remote server's hostname now when new key is
1688 received during connection process. Affected file is
1689 irssi/src/silc/core/client_ops.c.
1691 * Return always our own public key to the client if it asks
1692 for it with GETKEY command. Affected file silcd/command.c.
1694 * Removed the use_auto_addr variable from default config
1695 file since it was in wrong section. Affected file is
1698 * Fixed TOPIC_CHANGE notification to not route it when it
1699 was sent using silc_server_send_notify_to_channel function.
1700 Affected file silcd/command.c.
1702 * Fixed silc_server_send_notify_kicked to send the kicker's
1703 Client ID also, it was missing. Affected files are
1704 silcd/command.c, silcd/packet_send.[ch].
1706 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1708 * Do not save client history information in SERVER_SIGNOFF.
1709 Fixes the bug in normal server that it does not detect
1710 the client becoming valid after the server becomes back
1711 online. Affected file silcd/server_util.c.
1713 * Added `sock_error' field into the SilcSocketConnection
1714 context. When error occurs during socket operation (read
1715 or write) the error is saved. Added also new function
1716 silc_socket_get_error to return human readable socket error
1717 message. Affected files are lib/silcutil/silcsockconn.[ch],
1718 lib/silcutil/unix/silcunixsockconn.c, and
1719 lib/silcutil/win32/silcwin32sockconn.c.
1721 * The server now prints the socket error message in the
1722 signoff for client. Affected file silcd/server.c.
1724 * Fixed the `created' channel information sending from router
1725 to server in JOIN command. Checks now whether the channel
1726 really was created or not and set it according that.
1728 Fixed the JOIN command to use the client entry's current
1729 ID during the joining procedure instead of the one it sent
1730 in the command (it is checked though), since it can change
1731 between the packet processing and command processing, and
1732 would just case unnecessary pain in the client end. Affected
1733 file silcd/command.c.
1735 * Fixed a channel key payload sending to use correct channel
1736 ID when the server was forced to change the channel's ID by
1737 router. Router sent the key payload with the old Channel ID.
1738 Affected file silcd/packet_receive.c.
1740 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1742 * Call silc_server_save_channel_key only if the key payload
1743 was provided in the JOIN command's command reply. Affected
1744 file silcd/command_reply.c.
1746 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1748 * Fixed silc_mp_sizeinbase to return the value correctly with
1749 MPI. Affected file lib/silcmath/mp_mpi.c.
1751 * Fixed the stop_server signal to correctly stop the scheduler
1752 and gracefully stop the server when SIGTERM or SIGINT signals
1753 are received. Affected file silcd/silcd.c.
1755 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1757 * Simple handling of TERM and HUP signals. Also added some log
1758 flushing call around. Affected file is
1761 * Fixed small bugs in silclog.c. Now buffering output will take
1762 effect after 10 seconds since startup: This will ensure that
1763 no important startup messages are lost. Also output redirection
1764 will preserve original format ([Date] [Type] message).
1765 Affected file is lib/silcutil/silclog.c.
1767 * Added two options to the config file, in the logging section:
1768 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1769 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1771 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1773 * Do not print the warning about log files not being initialized
1774 more than once to avoid excess logging. Affected file is
1775 lib/silcutil/silclog.c.
1777 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1778 the SIM copying in make install in Makefile.am.pre.
1780 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1782 * Rewritten silclog APIs. Globally interesting changes follows:
1783 silc_log_set_files() changed to silc_log_set_file().
1784 silc_log_set_callbacks() changed to silc_log_set_callback().
1785 ROBOdoc documented silclog header file.
1786 SilcLogCb now returns bool to wether inihibit the default
1787 handler or not (to keep the old behaviour return always TRUE).
1788 The new APIs should also fix the problem of the
1789 silcd_error.log file that was written in the current directory.
1792 Log files streams will remain opened after silc_log_set_file()
1793 call, means less CPU usage notably on high traffic servers.
1794 File streams are now full buffered, and flushed to the disk
1795 every 5 minutes, lesses HD activity and CPU usage.
1796 Messages can be redirected, allowing admins to configure
1797 one single logfile for all server messages.
1798 the silc_log_quick global variable to activate fast-logging.
1799 Affected files lib/silcutil/silclog.[ch]
1801 * Changed some code to conform new silclog APIs. Affected
1802 files are doc/example_silcd.conf.in, silcd/server.c
1803 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1806 * Fixed a memory leak that could occur in some situations.
1807 Affected file silcd/serverconfig.c.
1809 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1811 * Added the silc_client_del_client to remove the client from
1812 all channels as well. Affected file lib/silcclient/idlist.c.
1814 * Fixed the client library to correctly remove the client
1815 from all channels when the client entry is being destroyed.
1816 Affected file lib/silcclient/client_notify.c, command.c.
1818 * Added auto-nicking support to the client library. If the
1819 applicatio now sets client->nickname it will be sent to the
1820 server after connecting by the library. This way for example
1821 SILCNICK (or IRCNICK) environment variables will have effect
1822 and always change the nickname automatically to whatever
1823 it is wanted. Affected file lib/silcclient/client.[ch].
1825 * Renamed silc_server_command_bad_chars to the
1826 silc_server_name_bad_chars and moved it to the
1827 silcd/server_util.[ch]. Added also new function
1828 silc_server_name_modify_bad to return nickname that
1829 includes bad characters as new nickname without those
1830 bad characters. This check and modify is now used in
1831 silc_server_new_client when the username is initially set
1832 as nickname, so it must be checked to be valid nickname.
1833 Affected file silcd/packet_receive.c.
1835 * The nickname length is now taken from the packet for real
1836 and not trusted to strlen() since it clearly can return
1837 wrong length for nickname including bad characters. This
1838 also applies to channel names. Affected file silcd/command.c.
1840 * Removed the lib/silcsilm/modules directory. Modules are now
1841 compiled into the lib/silcsim. Fixed the copying of the
1842 modules to follow symbolic links in Makefile.am.pre.
1844 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1846 * Fixed silc_string_regexify list creation. Fixes bugs with
1847 BAN and INVITE commands in server. The affected file is
1848 lib/silcutil/unix/silcunixutil.c.
1850 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1852 * Removed the command destructor entirely from the server's
1853 command and command reply routines. It is not needed, and
1854 its usage was buggy and caused crashes. Affected files are
1855 silcd/command[_reply].[ch].
1857 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1859 * Cancel protocol and NULL sock->protocol if timeout
1860 occurred during protocol. Affected file silcd/server.c.
1862 * Cancel protocol timeouts always before calling the final
1863 callback, to assure that after final callback is called
1864 no other state will be called for the protocol anymore.
1865 Affected file silcd/protocol.c.
1867 * Print error log if incoming connection configuration could
1868 not be found. Affected file silcd/server.c.
1870 * Fixed JOIN command to correctly save the founder mode
1871 to the client on normal SILC server, when the channel
1872 was created by the router. Affected file silcd/command.c.
1874 * Fixed LIST command (hopefully) to send correct reply
1875 packets. Affected file silcd/command.c.
1877 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1879 * The silc_packet_receive_process now returns FALSE if the
1880 read data was invalid packet, and TRUE if it was ok.
1882 The server now checks that if unauthenticated connection
1883 sends data and its processing fails the server will close
1884 the connection since it could be a malicious flooder.
1886 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1888 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1890 * Make sure the warning about error opening a log file is
1891 printed only once and not everytime it fails (produces
1892 too much useless log). Affected file lib/silcutil/silclog.c.
1894 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1896 * Made the silc_server_daemonise() function more readable.
1897 Affected file silcd/server.c.
1899 * Pid file is now optional, the user may comment it out from
1900 the config file. Removed define SILC_SERVER_PID_FILE, we
1901 don't need a default any longer. Affected file
1902 configure.in.pre, lib/Makefile.am.pre.
1904 * Make some use of the pid file. The server now dies at startup
1905 if it detects a valid pid file on his path. The server would
1906 die anyway in this circumstance, because of the bind() failure.
1907 Affected file silcd/silcd.c.
1909 * No longer compiling lib/dotconf.
1911 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1913 * Fixed JOIN command parsing not to crash. Affected file
1914 lib/silcclient/command.c.
1916 * Fied the NICK_CHANGE notify to add the new client entry
1917 even it is resolved. This removes an <[unknown]> nick
1918 thingy bug in the client. Affected file is
1919 lib/silcclient/client_notify.c.
1921 * Do not try to allocate 0 bytes (efence does not like it)
1922 in lib/silccore/silccomand.c when encoding payload.
1924 * Do not take IRCNICK as nickname in Irssi SILC client since
1925 it is not possible to set nickname before hand connecting
1926 the server (TODO has an entry about adding auto-nicking
1929 * Changed the silc_server_command_pending to check whether
1930 there already exists an pending entry with the specified
1931 command, command identifier and pending callback. This is
1932 to fix IDENTIFY and WHOIS related crashes that may register
1933 multiple pending commands with same identifier. Affected
1934 file silcd/command.c.
1936 * Fixed the server to reconnect to the router even if it
1937 was already reconnecting and EOF was received. This to
1938 fix a possibility that the server wouldn't ever try to
1939 auto-reconnect to the router. Affected file silcd/server.c.
1941 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1943 * Fixed the server's password authentication to use the
1944 length of the locally saved password, and not the one
1945 sent in the packet. Affected file silcd/protocol.c.
1947 * Fixed same password authentication problem in the
1948 Authentication Payload handling routines in
1949 lib/silccore/silcauth.c.
1951 * Yet another password authentication problem fixed with
1952 channel password handling in silcd/command.c.
1954 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1956 * If first character of string in silc_parse_userfqdn is '@'
1957 then do not parse it. Affected file is
1958 lib/silcutil/silcutil.c.
1960 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1962 * Fixed minor bug in IDENTIFY command reply sending, which
1963 caused various weird problems during JOIN when it was
1964 resolving names for users. Affected file silcd/command.c.
1966 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1968 * Fixed the IDENTIFY command reply sending to chech better valid
1969 clients. It was possible to send incomplete list of replies.
1970 Affected file silcd/command.c.
1972 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1974 * Added silc_client_command[s]_[un]register functions now to
1975 dynamically register the commands in client library. Removed
1976 the static table of commands. This allows the client library
1977 to call commands without causing the application to know about
1978 what commands library has called.
1980 Removed the INFO command reply kludge to detect when the command
1981 was called by library. Now library use its own command reply
1982 function for INFO command.
1984 Added function silc_client_command_call to call a command.
1985 Application can use it to call command, not access the structure
1988 Now all commands that are sent by the client library (not
1989 explicitly sent by application) use own command reply functions.
1991 Affected files around lib/silcclient/ and in
1992 irssi/src/silc/core/.
1994 * Fixed the WHOIS command reply sending to chech better valid
1995 clients. It was possible to send incomplete list of replies.
1997 Fixed the WHOIS and IDENTIFY to send the request to router
1998 if normal server did not do it and did not find any results.
2000 Affected file silcd/command.c.
2002 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2004 * Moved the internal data from SilcClient context into its
2005 own file, not accesible to application. Affected files
2006 lib/silcclient/client.h and lib/silcclient/client_internal.h,
2007 and other files in client library.
2009 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2011 * Added doc/examples installation target in Makefile.am.pre.
2014 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2016 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
2017 commands the found client entry will be removed from the
2018 cache, after notifying application about the error. Affected
2019 file lib/silcclient/command_reply.c.
2021 * Changed the /MSG to check for exact nickname user gave, and
2022 not let `nick' match `nick@host' if it is only one found. Now,
2023 user must type the exact nickname (like nick@host2) even if
2024 there are no more than one same nicks found. This is to avoid
2025 a possibility of sending nickname to wrong nickname since
2026 `nick' could match `nick@host'. Affected file is
2027 irssi/src/core/silc-servers.c.
2029 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2031 * Do not print "you are now server operator" or similar when
2032 giving /away command. Affected files are
2033 irssi/src/silc/core/client_ops.c, silc-servers.h.
2035 * Made the silc_server_command_pending_error_check to send
2036 the same command reply payload it received back to the
2037 original sender of the command. This way all arguments
2038 that was received by the server will be received by the
2039 client too. Affected file silcd/command.c.
2041 * Added the silc_idcache_add to return the created cache entry
2042 to a pointer. Affected file lib/silccore/silcidcache.[ch].
2044 * Add global clients to expire if they are not on any channel.
2045 This is because normal server will never know if they signoff
2046 if they are not on any channel. The cache expiry will take
2047 case of these entries. This is done by normal servers only.
2048 The affected files are silcd/command_reply.c,
2049 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
2051 * If server receives invalid ID notification for WHOIS or
2052 IDENTIFY and the ID exists in the lists, it is removed.
2053 Affected file silcd/command_reply.c.
2055 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
2056 in client then client entry that it matches is searched and
2057 the nickname is printed on the screen for user. Affected
2058 file irssi/src/silc/core/client_ops.c.
2060 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2062 * Use cache entry expire time in the LIST command reply to
2063 purge old entries from the cache after the LIST command
2064 reply has been received. This way we don't have non-existent
2065 entries in the cache for too long. Affected file is
2066 silcd/command_reply.c.
2068 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2070 * If we are normal server, and we've not resolved client info
2071 in WHOIS or IDENTIFY from router, and it is global client,
2072 we'll check whether it is on some channel. If it is not
2073 then we cannot be sure about its validity and will resolve it
2074 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
2075 file silcd/command.c.
2077 * Search channel by name (if possible) rather than by ID
2078 in IDENTIFY command's command reply. Affected file is
2079 silcd/command_reply.c.
2081 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>

2084 Updated specs and implemented it. Affected file silcd/command.c,
2085 silcd/packet_send.c and silcd/packet_receive.c.
2087 * Implemented the <founder auth> payload handling in the JOIN
2088 command. If provided all conditions for channel joining
2089 except requirement to provide correct passphrase can be
2090 overrided by the channel founder. Updated the protocol specs.
2091 Affected file silcd/command.c.
2093 Added support for founder auth in JOIN command in client
2094 library. Fixed the parsing of the JOIN command now to support
2095 all options as they should be. The affected file is
2096 lib/silcclient/command.c.
2098 * Optimized the WHOIS and IDENTIFY commands to send the request
2099 to router only if it includes nicknames or other names. If
2100 they include only IDs then check the local cache first before
2101 routing. Affected file is silcd/command.c.
2103 * Added channels topic announcements. Affected file is
2104 silcd/packet_receive.c and silcd/server.c.
2106 * Fixed the silc_server_send_notify_topic_set to really destine
2107 the packet to channel. Affected file silcd/packet_send.c.
2109 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
2110 library. Affected file lib/silcclient/client_notify.c.

2123 lib/silccore/silccommand.c
2124 lib/silccore/silcidcache.c
2129 * ROBOdoc documented the lib/silcske/groups.h file and a
2130 bit changed the interface for better.
2132 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2134 * Update the client entry context in the ID cache after
2135 nick change. Affected file lib/silcclient/command.c.
2136 Fixes the CUMODE command when regaining founder privileges,
2137 and a little WHOIS problem.
2139 * Fixed silc_net_gethostbyname to correctly call the
2140 inet_ntop. Affected file lib/silcutil/silcnet.c.
2142 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2144 * Added IPv6 support checking to the configure.in.pre, added
2145 also --enable-ipv6 option to override the check. Affected
2146 file configure.in.pre.
2148 * The silc_thread_create now calls the start function
2149 directly if threads support is not compiled in. Removes
2150 ugly #ifdef's from generic code. Affected files are
2151 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
2153 * Added silc_net_gethostby[name/addr]_async to asynchronously
2154 resolve. Affected files are lib/silcutil/silcnet.[ch].

2157 channel IDs. Affected file lib/silcutil/silcutil.c.
2159 * Added support for creating IPv6 based server IDs. Affected
2160 file is silcd/serverid.c.
2162 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2164 * Added silc_net_gethostby[addr/name] into the
2165 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
2166 routines. Added silc_net_is_ip[4/6]. Affected file is
2167 lib/silcutil/unix/silcunixnet.c. All routines that take
2168 address as argument now supports both IPv4 and IPv6 addresses.
2170 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2172 * Fixed LIST command reply sending in server. Affected file
2175 * Server now sends the kicker's client ID in the KICK notify
2176 to the kicked client. Affected file silcd/command.c.
2178 * The client library now parses the kickers client ID and
2179 UI displays it. Affected files lib/silcclient/client_notify.c
2180 and irssi/src/silc/core/silc-channels.c, module-formats.c.
2182 * Made all payload parsing function prototypes consistent.
2183 They all take now const unsigned char * and uint32 pair as
2184 the payload data instead of SilcBuffer. Changes all around
2185 the source tree. Other unsigned char* -> const unsigned char*
2186 changes around the tree as well.
2188 * Optimized SFTP client and server packet sending not to
2189 allocate new buffer for each packet but to recycle the
2190 first allocated buffer. Affected files are
2191 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
2193 * Optimized the SFTP client to use SilcList instead of
2194 SilcDList for requests, because it is faster. Affected file
2195 is lib/silcsftp/sftp_client.c.
2197 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
2198 into lib/silccore/silcid.[ch].
2200 Renamed silcpayload.[ch] into silcargument.[ch].
2202 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2204 * If client entry is deleted with active key agreement
2205 session, abort the session.
2207 The silc_client_abort_key_agreement now calls the completion
2208 callback with new SILC_KEY_AGREEMENT_ABORTED status.
2210 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
2213 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2215 * Don't use __restrict in older GCC's. Affected file is
2216 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
2218 * silc_net_localhost now attempts to reverse lookup the
2219 IP/hostname. Affected file lib/silcutil/silcnet.c.
2221 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
2222 command. It can be used to gain founder privileges at
2223 the same time when joining the channel.
2225 Defined that the SILC_NOTIFY_TYPE_KICKED send the
2226 kicker's client ID as well. Updated protocol specs.
2228 Defined that the server must send SILC_COMMAND_IDENTIFY
2229 command reply with error status to client who sent
2230 private message with invalid client ID.
2232 Updated the protocol specification.
2234 * Added silc_server_send_command_reply to send any
2235 command reply. Affected file silcd/packet_send.[ch].
2237 * Added silc_id_payload_encode_data to encode ID payload
2238 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
2240 * The server now send IDENTIFY command reply with error
2241 status if client ID in private message is invalid. Affected
2242 file silcd/packet_receive.c.
2244 * Save the server key file with server's IP address in
2245 the filename instead of hostname. The affected file is
2246 irssi/src/silc/core/client_ops.c.
2248 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2250 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
2253 * Added libtool support for compiling shared objects in
2254 lib/silcsim. Affected file configure.in.pre and
2255 lib/silcsim/Makefile.am. Original patch by cras.
2257 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2259 * Pid file configuration, and server's config file fixes
2260 patch by toma. Updated CREDITS file.
2262 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2264 * Fixed silc_client_channel_message to not try to decrypt
2265 the message twice if it resolved the destination client
2266 information. This could cause of dropping one channel
2267 message. Affected file lib/silcclient/client_channel.c.
2269 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2271 * Added silc_client_run_one into lib/silcclient/silcapi.h and
2272 lib/silcclient/client.c. This function is used when the SILC
2273 Client is run under some other scheduler, or event loop or
2274 main loop. On GUI applications, for example this may be
2275 desired to used to run the client under the GUI application's
2276 main loop. Typically the GUI application would register an
2277 idle task that calls this function multiple times in a second
2278 to quickly process the SILC specific data.
2280 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2282 * Fixed silc_server_drop() for dropping the supplementary
2283 groups as well, this could cause a security hole on some
2286 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2288 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
2291 * Write PID file after dropping privileges. Added -F option
2292 to run server on foreground. A patch by debolaz.
2293 Affected files silcd/server.c, silcd/silcd.c.
2295 * Fixed MOTD to return the MOTD file server name. Affected
2296 file silcd/command.c.
2298 * Added INFO command reply handling to the Irssi SILC Client.
2299 Affected file irssi/src/silc/core/client_ops.c.
2301 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2303 * Fixed the silc_idcache_list_* routines to really support
2304 the dynamic list. Fixes a crash. Affected file is
2305 lib/silccore/silcidcache.c.
2307 * Fixed the LIST command reply to really call LIST command's
2308 pending callbacks. Affected file silcd/command_reply.c.
2310 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2312 * Update conn->local_entry->nickname after giving NICK
2313 command. Affected file lib/silcclient/command.c.
2315 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
2317 * Added the [pid] option to the silcd configuration file
2319 Affected files: serverconfig.[ch] and silcd.c
2321 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2323 * Save fingerprint in WHOIS command reply in server.
2324 Affected file silcd/command_reply.c.
2326 * Fixed NICK commands pending callback registration.
2327 Affected file lib/silcclient/command.c.
2329 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2331 * Use ++server->cmd_ident when sending commands in server,
2332 instead of random number. Affected file silcd/command.c.
2334 * Fixed GETKEY command reply to call actually GETKEY pending
2335 command callbacks. Affected file silcd/command_reply.c.
2337 * A bit stricter check for nicknames. Check for same nickname
2338 in NICK command also. Affected file silcd/command.c.
2340 * Do not call INFO command everytime client ID changes, only
2341 during first connecting. Affected file lib/silcclient/client.c.
2343 * Set the new nickname only after successful command reply for
2344 NICK command is returned by server. Affected file
2345 lib/silcclient/command.c.
2347 * Remove nicknames from nicklist during server_signoff notify.
2348 Should fix /NAMES bit more. The affected file is
2349 irssi/src/silc/core/silc-channels.c.
2351 * Added `fingerprint' field to the SilcIDListData in the
2352 silcd/idlist.h to hold the fingerprint of the client's
2355 Send the fingerprint of the client's public key in WHOIS
2358 Affected files silcd/command.c, and silcd/idlist.[ch].
2360 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
2361 create fingerprint from given data.
2363 * Show the fingerprint of the client's public key in WHOIS.
2364 Affected files irssi/src/module-formats.[ch] and
2365 irssi/src/silc/core/client_ops.c.
2367 * Format the multiple same nicknames also during JOIN and
2368 NICK_CHANGE notifys. Affected file is
2369 lib/silcclient/client_notify.c.
2371 * Do not print error on screen for invalid private message
2372 payload since it can come if someone is sending private
2373 messages with wrong key. Affected file
2374 lib/silccore/silcprivate.c.
2376 * Fixed multiple concurrent /PING crash. Affected file
2377 lib/silcclient/command.c.
2379 * Changed the wrong ID encoding. All IP addresses must be
2380 in MSB first order in encoded format. They were encoded
2381 wrong and was in LSB format. Affected files are
2382 silcd/serverid.c, lib/silcutil/silcutil.c.
2384 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
2386 * Call the `connect' client operation through the scheduler
2387 in case of error. Affected file lib/silcclient/client.c.
2389 * Call the `failure' client operation even if the error
2390 occurred locally during a protocol. Affected file is
2391 lib/silcclient/protocol.c.
2393 * Added support of sending LIST command to router from normal
2394 server. This way normal server can get list of all channels
2395 in the network too. Fixed the channel list sending in the
2396 server too. Affected files are silcd/command.c, and
2397 silcd/command_reply.[ch].
2399 * Added silc_server_update_channels_by_server and
2400 silc_server_remove_channels_by_server. They are used during
2401 disconnection of primary router and in backup router protocol.
2402 Affected file silcd/server_util.[ch], silcd/server.c and
2403 silcd/server_backup.c.
2405 * Fixed channel adding to global list in IDENTIFY command
2406 reply in server. Affected file silcd/command_reply.c.
2408 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2410 * If the incoming packet type is REKEY or REKEY_DONE process
2411 that packet always synchronously. Fixes yet another MAC
2412 failed error on slow (dialup) connections. Affected file
2413 lib/silcclient/client.c and silcd/server.c.
2415 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2417 * Call check_version SKE callback for initiator too. Affected
2418 file lib/silcske/silcske.c.
2420 * Implemented fix for security hole found in the SKE that was
2421 fixed in the specification few days back; the initiator's
2422 public key is now added to the HASH value computation.
2423 Added backwards support for the old way of doing it too, for
2424 old clients and old servers. Affected file is
2425 lib/silcske/silcske.c.
2427 * Enabled mutual authentication by default in SKE. If initiator
2428 is not providing mutual authentication the responder will
2429 force it. This will provide the proof of posession of the
2430 private key for responder. The affected files are
2431 lib/silcclient/protocol.c and silcd/protocol.c.
2433 * Do not cache anymore the server's public key during SKE.
2434 We do mutual authentication so the proof of posession of
2435 private key is done, and if the server is authenticated in
2436 conn auth protocol with public key we must have the public
2437 key already. Affected file silcd/protocol.c.
2439 * Added new global debug variable: silc_debug_hexdump. If
2440 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
2441 file lib/silcutil/silclog.[ch].
2443 * Fixed compilation warning due to char * -> const char *.
2444 Affected files lib/silcutil/silcnet.h, and
2445 lib/silccore/silcauth.[ch].
2447 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2449 * Fixed CMODE command when new channel key was created. If
2450 the creation failed the old key was removed. Next time giving
2451 same command would crash the server since the old key was
2452 freed already. Affected file silcd/command.c.
2454 * Fixed the silc_server_announce_get_channels to not crash
2455 on reconnect. Affected file silcd/server.c.
2457 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2459 * Added silc_log_set_debug_string function to set a regex
2460 string to match for debug output. Only the function names,
2461 or filenames matching the given debug string is actually
2462 printed. This way it is possible to filter out those debug
2463 strings that user is not interested in.
2465 Fixed a bug in silc_string_regexify.
2467 Affected files lib/silcutil/silclog.[ch], and
2468 lib/silcutil/unix/silcunixutil.c.
2470 * Changed the -d options in both server and Irssi SILC client
2471 to take the debug string as argument. Affected files
2472 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
2474 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2476 * Added silc_hash_babbleprint to create a Bubble Babble
2477 Encoded fingerprint. The encoding is developed by Antti
2478 Huima (draft-huima-babble-01.txt), and it creates human
2479 readable strings out of binary data. Affected file
2480 lib/silccrypt/silchash.[ch].
2482 * Print the babble print now in addition of fingerprint as well
2483 in Irssi SILC client. Affected files are
2484 irssi/src/fe-common/silc/module-formats.[ch],
2485 irssi/src/fe-common/silc/core/client_ops.c.
2487 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2489 * Fixed a security problem found in SKE. The initiator's
2490 public key too is now added to the HASH hash value creation
2491 which is signed by the responder to create the SIGN value.
2492 This will prevent anyone in the middle to lie to the responder
2493 about the initiator's public key. If this is done now, the
2494 man in the middle will get caught. Updated the protocol
2497 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2499 * Better installation directory handling. Configure module
2500 paths and other paths automatically to example_silc* files
2501 in doc/. A patch by toma.
2503 * Fixed compiler warning from MPI library, and from SILC RNG.
2506 * Added SILC_SERVER_PID_FILE to define the pid file for server.
2507 It can be configured with ./configure. A patch by toma.
2509 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2511 * Find correct make to use in prepare-clean. A patch by
2512 toma. Affected file prepare-clean.
2514 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
2516 * Added irssi variables use_auto_addr, auto_bind_ip,
2517 auto_bind_port and auto_public_ip.
2519 * Changed the interface for silc_client_send_key_agreement
2520 in lib/silcclient/silcapi.h
2524 irssi/src/silc/core/silc-core.c
2526 lib/silcclient/silcapi.h
2527 irssi/src/silc/core/silc-channels.c
2528 lib/silcclient/client_keyagr.c
2531 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2533 * Added silc_pkcs_public_key_compare to compare two
2534 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
2536 * Check that the client who set the founder mode on the
2537 channel is the same client that is giving the founder
2538 mode to itself. It is done by comparing the saved public
2539 key (it is saved even in the authentication is passphrase).
2540 Affected file silcd/command.c.
2542 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2544 * Do not process packet for disconnected socket connection.
2545 Affected file lib/silccore/silcpacket.c.
2547 * Process the DISCONNECT packet through scheduler in the
2548 client library. Affected file lib/silcclient/client.c.
2550 * Fixed the silc_client_packet_parse to not to increase
2551 the packet sequence number if the conn->sock and the
2552 current socket connection is not same. This can happen
2553 for example during key agreement when the conn includes
2554 multiple socket connections (listeners). Affected file
2555 lib/silcclient/client.c.
2557 * The sender of the file transfer request now provides also
2558 the pointer (listener) for the key exchange protocol. If
2559 the listener cannot be created then it sends empty key
2560 agreement and lets the receiver provide the listener.
2562 Added `local_ip' and `local_port' arguments to the
2563 silc_client_file_send. If they are provided they are used,
2564 if not then it will attempt to find local IP address, if
2565 not found or bind fails then the remote client will provide
2568 Affected files are lib/silcclient/client_ftp.c and
2569 lib/silcclient/silcapi.h.
2571 * Extended the FILE SEND command to support defining the
2572 local IP and port for key exchange listener. They are
2573 optional. Affected file irssi/src/silc/core/silc-servers.c.
2575 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2577 * Defined to WHOIS command reply the sending of fingerprint
2578 of the client's public key (if the proof of posession of the
2579 corresponding private key is verified by the server).
2580 Updated to the protocol specification.
2582 * Added support of receiving the client's public key's
2583 fingerprint in command reply in client library. Affected
2584 file is lib/silcclient/command_reply.c, and
2585 lib/silcclient/idlist.[ch].
2587 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2589 * Do not send over 128 chars long nickname to the server
2590 in NICK command. Affected file lib/silcclient/command.c.
2592 * Do not send over 256 chars long channel names to the server
2593 in JOIN command. Affected file lib/silcclient/command.c.
2595 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2597 * Assure that silc_server_close_connection cannot be called
2598 twice for same socket context. Affected file is
2601 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2603 * Send error message to application if opening file for
2604 writing during file transfer fails. Affected file is
2605 lib/silcclient/client_ftp.c.
2607 Remove all file transfer sessions for a client that we're
2608 removing from ID cache.
2610 Affected file is lib/silcclient/client_ftp.c.
2612 * Fixed silc_net_addr2bin to return correct address. Affected
2613 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2615 * Fixed file transfer session removing on signoff notify.
2616 Affected file irssi/src/silc/core/silc-servers.c.
2618 * Added the SilcClientFileError to be returned in the monitor
2619 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.

2640 client library. Affected file lib/silcclient/client_prvmsg.c.
2642 * Do not actually remove the client directly from ID cache
2643 during SERVER_SIGNOFF, but invalidate it. This way we
2644 preserve the WHOWAS info for the client. Affected file
2645 silcd/server_util.c.
2647 * Fixed SERVER_SIGNOFF notify handling in the server. The
2648 server is now able to process incoming SERVER_SIGNOFF notify
2649 for a server that it doesn't even know about. It will remove
2650 the clients provided in the notify. Affected file
2651 silcd/packet_receive.c.
2653 * Check for partial packet in data queue after every packet that
2654 was found from the queue. Return and wait for more data if
2655 there is partial data in queue. Affected file is
2656 lib/silccore/silcpacket.c.
2658 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>

2666 * Check that newsize in silc_buffer_realloc is larger than
2667 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
2669 * Added better monitor of file transfers. It now monitors
2670 key agreement protocol during the file transfer too. Added
2671 error reporting too. Affected files
2672 irssi/src/silc/core/silc-servers.c,
2673 irssi/src/fe-common/silc/module-formats.[ch].
2675 * Wrote a help file for FILE command.
2677 * Added silc_rng_global_get_byte_fast to get not-so-secure
2678 random data as fast as possible. Random data is read from
2679 /dev/urandom if available and from the SILC RNG if not
2680 available. It is used in padding generation. Affected file
2681 lib/silccrypt/silcrng.[ch].
2683 * All packets in client library are now processed synchronously.
2684 Optimized packet processing a lot. Affected file
2685 lib/silcclient/client.c.
2687 * All server connection packets are processing synchronously
2688 now in server, to optimize packet processing. Affected file
2691 * Include files are installed now only in Toolkit distribution
2692 if make install is given. Affected files: all Makefile.am's.
2694 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2696 * Assure that silc_client_notify_by_server_resolve does not
2697 resolve the client information multiple times. If it cannot
2698 be found by the first it cannot be found at all. Affected
2699 file lib/silcclient/client_notify.c.
2701 * Fixed WHOWAS command reply calling. Affected file
2702 lib/silcclient/command_reply.c.
2704 * Removed all references to silc_idlist_get_client from the
2705 Irssi SILC client since that call is internal call used by
2706 the library. The Irssi SILC client will use now client
2707 retrieval functions found in silcapi.h.
2709 * Fixed a bug in resolving nickname info before sending
2710 private message. It used freed memory. Affected file
2711 irssi/src/silc/core/silc-servers.c.
2713 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2715 * Assure my_channels statistics cannot go negative in server.
2716 Affected files silcd/server.c, silcd/server_util.c.
2718 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

2732 * Added silc_net_localip to return local host's IP address.
2733 Affected file lib/silcutil/silcnet.[ch].
2735 * If key exchange or rekey protocol is active for a connection
2736 parse all packets syncronously since there might be packets
2737 in packet queue that we are not able to process without first
2738 processing packets before them. Affected file silcd/server,
2739 lib/silcclient/client.c.
2741 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2742 whether library should continue processing the packet.
2743 Affected file lib/silccore/silcpacket.h.
2745 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and

2774 lib/silcutil/silcutil.[ch].
2776 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2778 * Resolve the client info when received private message or
2779 channel message for a client which nickname we don't know.
2780 Affected files lib/silcclient/client_prvmsg.c and
2781 lib/silcclient/client_channel.c.

2784 file irssi/src/silc/core/silc-channels.c.
2786 * Added SilcClientStatus field to the SilcClientEntry in the
2787 lib/silcclient/idlist.h.
2789 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
2790 is incomplete and is being resolved, it won't be resolved
2793 Make sure also that USERS command reply does not resolve
2794 twice information. Affected file is
2795 lib/silcclient/command_reply.c.
2797 Make sure that silc_client_get_clients_by_list does not
2798 resolve twice same information.
2800 * Check for valid client->id in the silc_server_free_client_data.
2801 Affected file silcd/server.c.
2803 * Fixed /GETKEY nick@server not to crash if the server entry
2804 is not found. Affected file lib/silcclient/command.c.
2806 * Fixed the silc_server_check_cmode_rights to check the
2807 requested modes correctly. Affected file silcd/command.c.

2811 * Better checks for non-printable chars in nick added.
2812 Affected file silcd/command.c.
2814 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2816 * Call the silc_server_udpate_servers_by_server in the
2817 primary router that comes back online in the backup resuming
2818 protocol. Otherwise it routes packets wrong. Affected file
2819 silcd/server_util.[ch], silcd/server_backup.c.
2821 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2823 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2824 lib/silcutil/silcbuffmt.[ch].
2826 * Redefined the SILC packet header to include the padding
2827 length. Affected file lib/silccore/silcpacket.[ch].
2829 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2830 length for maximum padding up to 128 bytes). Affected
2831 file lib/silccore/silcpacket.h.
2833 * Removed all backwards support for old 0.5.x MAC thingies.
2834 The SILC packet header change makes it impossible to be
2835 backwards compatible.
2837 * Send the ENDING packet with timeout in the backup resuming
2838 protocol. This is to assure that all routers has connected
2839 to the primary router. Affected file silcd/server_backup.c.
2841 * Changed the RNG to take the first IV from random data. It
2842 used to take it from zero actually. Changed the RNG also
2843 to use /dev/urandom during session. /dev/random is used
2844 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2846 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2848 * Changed the SILC packet header to have the first two bytes
2849 (the packet length) encrypted. Affected files aroung the
2850 code tree, lib/silccore/silcpacket.[ch]. Removed the
2851 SilcPacketCheckDecrypt callback. It is not needed anymore
2852 since the silc_packet_receive_process will determine now
2853 whether the packet is normal or special.
2855 * Implemented the unidirectional MAC keys. Affected files
2856 lib/silcske/silcske.c, silcd/protocol.c and
2857 lib/silcclient/protocol.c.
2859 * Implemented the packet sequence number to the MAC computation.
2860 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
2861 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
2862 lib/silcclient/protocol.c.
2864 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2866 * Allow backup router to announce servers. All servers
2867 announced by backup router are added to the global list
2868 automatically. Update hte server's socket to our primary
2869 router also when backup router announces a server.
2870 Affected file silcd/packet_receive.c.
2872 * Do not update the client->router in the function
2873 silc_server_udpate_clients_by_server if the client is on
2874 global list. We might fail to find any specific server
2875 for locally connected clients and local cell clients. They
2876 should still use the `from' and not `to' as client->router.
2877 This fixes backup router resuming protocol. Affected file
2878 silcd/server_util.c.
2880 * Decrease channel statistics count only if the channel
2881 deletion worked. Affected files are silcd/server.c and
2882 silcd/server_util.c.
2884 * Added silc_server_update_servers_by_server to update origin
2885 of all server entries. Used during backup router protocol.
2886 Affected files silcd/server_util.[ch], silcd/server.c. and
2887 silcd/backup_router.c.
2889 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
2890 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
2891 silc_hmac_get_hash and silc_hmac_get_name. Affected file
2892 lib/silccrypt/silchmac.c.
2894 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2896 * Assure that router cannot reroute the same channel message
2897 to the sender. Affected file silcd/packet_receive.c.
2899 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2901 * Made better checks that the channel message is not sent
2902 to the router it came from. Affected file is
2903 silcd/packet_send.c. Fixed memory leak too.
2905 * Announce informations for incoming router connection, but
2906 only after checking if it is replaced by backup router.
2907 Affected file silcd/packet_receive.c.
2909 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2911 * Fixed the backup resuming protocol to work in multiple
2912 router environment. Affected file silcd/server_backup.c.
2914 * Route packet only to one router in the function
2915 silc_server_packet_send_to_channel. Affected file is
2916 silcd/packet_send.c.
2918 * Fixed silc_server_send_notify_dest to set the broadcast
2919 flag. Fixed the silc_server_send_notify_topic to actually
2920 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2921 Affected file silcd/packet_send.c.
2923 * Changed the SFTP Filesystem interface. Changed the
2924 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2925 the filesystem operation function. The SilcSFTPFilesystem
2926 is now a context that is allocated by all filesystem allocation
2927 functions and it already includes the operations structure
2928 and filesystem specific context. It is given as argument
2929 now to the silc_sftp_server_start. This made the interface
2930 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2931 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2933 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2935 * Changed the backup router adding and getting interfaces
2936 in the server. The router that will be replaced by the
2937 specified backup router is now sent as argument. Affected
2938 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2941 * Added silc_net_addr2bin_ne to return the binary form of
2942 the IP address in network byte order. Affected files
2943 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
2945 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2947 * Check for existing server ID in silc_server_new_server
2948 and in silc_server_connect_to_router_final and remove the
2949 old entry if it exists. Affected file silcd/packet_receive.c,
2952 * Send the channel message always to only one router, either
2953 in upstream or downstream. Affected file is
2954 silcd/packet_send.c.
2956 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2958 * Wrote the definition of the backup resuming protocol to the
2959 protocol specification.
2961 * Removed one redundant channel key generation from normal
2962 server during joining procedure. Removed one redundant
2963 channel key sending from server to router during joining
2964 procedure. Affected file silcd/command.c.
2966 * Made minor bugfixes to the backup router resuming protocol.
2967 Affected file silcd/server_backup.c, server.c.
2969 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2971 * Added --disable-asm configuration option. Affected files
2972 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
2975 * Implemented the backup resuming protocol that is used to
2976 resume the primary router position in the cell after the
2977 primary router comes back online. Affected files
2978 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
2979 and silcd/server_util.[ch].
2981 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2983 * Sleep two (2) seconds after sending QUIT command to server.
2984 Affected file lib/silcclient/command.c.
2986 * Assure that if outgoing data buffer is pending do not force
2987 send any data. Affected file silcd/packet_send.c.
2989 * Assure that if outgoing data buffer is pending do not force
2990 send any data. Affected file lib/silcclient/client.c.
2992 * Implemented the backup router support when the primary router
2993 goes down. The servers and routers can now use the backup
2994 router as new primary router without loosing connectivity.
2996 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2998 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
2999 in the server to indicate disabled entry. All data read
3000 from the connection will be ignored and no data is sent
3001 for entry that is disabled. Affected files are
3002 silcd/idlist.h, silcd/server.c.
3004 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3006 * Created SFTP client and server test programs in the
3007 lib/silcsftp/tests directory.
3009 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3011 * Implemented memory filesystem (virtual filesystem) for
3012 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
3015 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3017 * Implemented the SFTP (SSH File Transfer Protocol) to the
3018 lib/silcsftp. It includes SFTP client and SFTP server
3021 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3023 * Moved lib/silccore/silcprotocol.[ch] to the
3024 lib/silcutil library.
3026 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
3027 take variable argument list pointer as argument. Affected
3028 file lib/silcutil/silcbuffmt.[ch].
3030 * Added silc_buffer_set function that is used to set data
3031 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
3032 Affected file lib/silcutil/silcbuffer.h.
3034 * Changed various routines in the core library to use the new
3035 silc_buffer_set instead of allocating new buffer only for
3038 * Added 64-bit value formatting and unformatting support to the
3039 silc_buffer_[un]format routines. Affected file is
3040 lib/silcutil/silcbuffmt.[ch].
3042 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
3043 to includes/bitmove.h.
3045 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3047 * Fixed channel user mode saving in client library. Affected
3048 file lib/silcclient/command[_reply].c.
3050 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3052 * Defined the file transfer to the SILC Protocol. Added
3053 new packet type SILC_PACKET_FTP and defined File Transfer
3054 Payload. The mandatory file transfer protocol is SFTP
3055 (SSH File Transfer Protocol). Affected file in addition
3056 of the internet draft is lib/silccore/silcpacket.h.
3058 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
3059 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
3060 is used as part of backup router protocol when the primary
3061 router of the cell is back online and wishes to resume
3062 the position as primary router.
3064 * Redefined the MAC generation keys in the protocol. The
3065 same key is not used anymore in both direction. Both
3066 direction will now use different keys for sending and
3067 receiving. This fixes a potential security flaw. This
3068 change causes incompatibilities in the protocol.
3070 * Redefined also the MAC computation from the packet.
3071 An packet sequence number is now added to the MAC
3072 computation. This prevents possible replay attacks against
3073 the protocol. This change too causes incompatibilities
3076 Added `sequence' field to the SilcPacketContext to hold
3077 the current sequence number for the packet.
3079 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3081 * Added `created' field to the SilcIDListData in the file
3082 silcd/idlist.h to indicate the time when the entry was
3085 * Added `created' field to the SilcChannelEntry too. Affected
3086 file silcd/idlist.h.
3088 * Added `creation_time' aguments to all the announcement functions
3089 in the server. If it is provided then only the entries that
3090 was created after the provided time frame are actually
3091 announced. Affected file silcd/server.[ch].
3093 * The protocol says that the Channel ID's IP address must be
3094 based on the router's IP address. Added check for this in
3095 the silc_server_new_channel when processing incoming New Channel
3096 Payload. Affected file silcd/packet_receive.c.
3098 * Print out the correct version with --version in SILC client.
3099 Affected file irssi/src/silc/core/silc-core.c.
3101 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3103 * Fixed WHOWAS command to check for completnes of the client
3104 entry always, not just when the command is coming from client.
3105 Affected file silcd/command.c.
3107 * Added new function silc_server_packet_queue_purge to purge the
3108 outgoing data queue to the network. After the function returns
3109 it is guaranteed that the outgoing packet queue is empty.
3110 Affected file silcd/packet_send.[ch].
3112 * Purge the outgoing packet queue in the rekey protocol's final
3113 callback to assure that all rekey packets go to the network
3114 before quitting the protocol. Affected file silcd/server.c.
3116 * Added silc_client_packet_queue_parse as similar function as
3117 in server to the client library. The affected file is
3118 lib/silcclient/client.c.
3120 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3122 * Splitted silcd/server.c and created silcd/server_util.[ch]
3123 for utility functions.
3125 * Added new socket flag SILC_SF_DISABLED to indicate that the
3126 connection is open but nothing can be sent to or received from
3127 the connection. Affected file lib/silcutil/silsockconn.[ch].
3128 The checking for disabled socket is checked in the low level
3129 silc_socket_write and silc_socket_read functions.
3131 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3133 * Allow only nicknames and channel names that fits into the
3134 7-bit unsigned char ASCII set. Affected file silcd/command.c.
3136 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3138 * When processing JOIN command reply in server check that if
3139 the channel exists in our global list we'll move it the local
3140 list. Affected file silcd/command_reply.c.
3142 * Fixed the check whether client is joined on the channel already
3143 in JOIN command. Affected file lib/silcclient/command.c.
3145 * Fixed the JOIN command reply to check whether the channel
3146 already exists. Affected file lib/silcclient/command_reply.c.
3148 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3150 * Added silc_ske_status_string to map the SKE error numbers
3151 to readable strings. The affected files are
3152 lib/silcske/silcske[_status].[ch].
3154 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3156 * Do not show the private channels on the WHOIS channel list
3157 as it is not allowed by the protocol. The affected file is
3160 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3162 * Assure that the packet length digged from the actual packet
3163 is something sensible in the silc_packet_decrypt_rest_special
3164 in lib/silccrypt/silcpacket.c.
3166 * Free and NULL the allocated pointer in silc_hmac_alloc if
3167 the HMAC allocation fails. The affected file is
3168 lib/silccrypt/silchmac.c.
3170 * Print the selected security properties to the log files in
3171 the server. Affected file silcd/protocol.c.
3173 * Add SKE's reference counter even if calling the completion
3174 callback manually. Otherwise it goes negative, although it
3175 does not cause any problems. The affected file is
3176 lib/silcske/silcske.c.
3178 * Remove the client entry with short timeout after giving the
3179 KILL command. Affected file lib/silcclient/command.c.
3181 * Fixed to send error reply in WHOIS and IDENTIFY commands in
3182 case all found clients are already disconnected (WHOWAS would
3183 found them) in the server. Affected file silcd/command.c.
3185 * Update the last_receive (time of last data received) to be
3186 updated only when received private or channel message so that
3187 the idle time showed in WHOIS makes more sense.
3189 * Added boolean field `valid' in to the SilcClientEntry in the
3190 client library to indicate whether the entry is valid or not.
3191 This fixes the nickname change bug on channel when changing
3192 the nickname to be same than the old (like nick to Nick) the
3193 nickname formatter doesn't set the new nick anymore to Nick@host.
3194 Affected file lib/silcclient/idlist.[ch].
3196 * Now actually fixed the nickname changing on disconnection.
3197 Added new function silc_change_nick to the Irssi SILC Client.
3198 Affected file irssi/src/silc/core/client_ops.c,
3199 irssi/src/silc/core/silc-nicklist.[ch].
3201 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3203 * Check that the public key exists in the GETKEY command before
3204 trying to encode it. Affected file silcd/command.c.
3206 * Print some notifications on received public keys with GETKEY
3207 command in the Irssi SILC Client. Affected files are
3208 irssi/src/fe-common/silc/module-formats.[ch],
3209 irssi/src/silc/core/client_ops.c.
3211 * Use IDENTIFY command to resolve the server information in the
3212 GETKEY command instead of INFO command. Affected file
3213 lib/silcclient/command.c.
3215 * All command reply functions in the client library now calls
3216 the pending command reply callbacks even if an error has
3217 occurred. The server has done this a long time and now it was
3218 time to move the client library to this as well. Now all
3219 errors can be delivered back to the pending command reply
3220 callbacks if necessary. Affected files are
3221 lib/silcclient/command[_reply].[ch].
3223 * Change the nickname on disconnection back to the username
3224 because in reconnect the server will enforce it to it anyway.
3225 Affected file irssi/src/silc/core/silc-servers.c.
3227 * Fixed a config file parsing bug in the Irssi SILC client.
3228 Affected file irssi/src/silc/core/clientconfig.c.
3230 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3232 * When printing the channel mode on JOIN, verify that the
3233 channel key and channel's HMAC are valid. Affected file
3234 irssi/src/silc/core/client_ops.c.
3236 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3238 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
3239 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
3240 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
3242 * Removed channel key rekey task deleting from the function
3243 silc_server_save_channel_key. Affected file silcd/server.c.
3244 Added explicit timeout task context instead that is used to
3245 delete the task if we are registering a new task before the
3246 new task has elapsed.
3248 * When channel key rekey occurs the client library now saves
3249 the old channel key for a short period of time (10 seconds) and
3250 is able to use it in case some is still sending channel
3251 messages encrypted with the old key after the rekey. Affected
3252 file lib/silcclient/[idlist.h|client_channel.c].
3254 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3256 * Added check to the silc_server_new_id_real to not accept
3257 new ID if it is the sender's own ID. Affected file is
3258 silcd/packet_receive.c.
3260 * Assure that we do not announce ourself or the one we've
3261 sending our announcements when we're router and are announcing
3262 servers to our primary router. Affected file silcd/server.c.
3264 * Fixed silc_server_command_identify_check_client to assemble
3265 correct WHOIS packet. It send corrupted WHOIS packet and
3266 caused problem with router to router connections. Affected
3267 file silcd/command.c.
3269 Fixed also silc_server_command_whois_check the same way
3270 as for the IDENTIFY command.
3272 * Added new SilcIDListStatus to the server in the SilcIDListData
3273 structure. The status now includes the current status of
3274 the entry (like registered, resolved etc.). Affected file
3275 silcd/idlist.[ch]. Defined a bunch of different status types
3276 as well. This replaced the old boolean registered field as well.
3278 Added resolve_cmd_ident field to the SilcClientEntry structure
3279 too so that if the entry is for example being resolved so
3280 another command may attach to the same pending command reply
3281 without requiring to resolve the same entry again. This concept
3282 should optimize the WHOIS and the IDENTIFY resolving under
3283 heavy load by taking away unnecessary resolving for entries
3284 that are being resolved already.
3286 Added support for adding multiple pending commands for one
3287 command idenfier. Affected file silcd/command[_reply].[ch].
3289 * Fixed WHOIS and IDENTIFY save to remove the cache entry
3290 before deleting the data. Otherwise the hash table will have
3291 freed data in comparison functions. Affected file is
3292 silcd/command_reply.c.
3294 * Fixed silc_idlist_replace_client_id to add the new entry to
3295 the cache with NULL nickname. Otherwise there will be invalid
3296 memory as the nickname after the nickname is freed. Affected
3297 file silcd/packet_receive.c.
3299 * Fixed the silc_idlist_get_clients_by_hash. The entries was
3300 saved into wrong slots because the previous number of entries
3301 was not taken into account. Affected file silcd/idlist.c.
3302 Fixed same thing in silc_idlist_get_clients_by_nickname too.
3304 * If we are router and we receive JOIN notify to a channel that
3305 does not have any users then notified client is marked as the
3306 channel founder, as it is it. The affected file is
3307 silcd/packet_receive.c
3309 * Added to the extended hash table API's table_del_*ext functions
3310 the destructor as argument too, so that the caller can decide
3311 which destructor to use or whether to use destructor at all.
3312 Affected file lib/silcutil/silchashtable.[ch].
3314 * Fixed ID Cache purging. It actually deleted the entries from
3315 the hash table after the data was freed. The hash table ended
3316 up comparing freed memory. The affected file is
3317 lib/silccore/silcidcache.c.
3319 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3321 * Fixed Irssi SILC client's KILL command's HELP syntax.
3323 * The USERS command now resolves the detailed user information
3324 if the userinfo field is missing. Affected file is
3325 lib/silcclient/command_reply.c.
3327 * Do not print error in silc_file_read if the read file does
3328 not exist. Just silently return NULL. Affected file is
3329 lib/silcutil/silcutil.c.
3331 * Fixed the silc_log_output to not wine about NULL filename
3332 and to not create some bogus " " filename. Affected file is
3333 lib/silcutil/silclog.c.
3335 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3337 * Fixed various printing bugs on the user interface in the
3338 Irssi SILC Client. Minor changes that were forgotten from
3341 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3343 * Fixed the configure.in.pre and the compilation and distribution
3344 environment to support the new autoconf 2.52. That version is
3345 now required to compile the CVS trunk.
3347 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3349 * Renamed function silc_parse_nickname to silc_parse_userfqdn
3350 to generally parse user@fqdn format strings. Affected file
3351 lib/silcutil/silcutil.c.
3353 * Added nickname_format and nickname_force_format fields to the
3354 SilcClientParams structure. The first one defines the format
3355 for the nicknames that the library will enforce if the receives
3356 multiple same nicknames. The second one is boolean value and
3357 can be used to force the library to always enforce the format
3358 to the nicknames regardles whether there are multiple nicknames
3359 or not. This configurable formatting was employed to flexibly
3360 support accessing multiple nicknames from the user interface.
3361 The userinterface can now set the nicknames to what ever format
3362 they prefer. Affected file lib/silcclient/silcapi.h.
3364 Added function silc_client_nickname_format to the file
3365 lib/silcclient/idlist.c. It performs the nickname formatting.
3367 Added new field `hostname´ to the SilcClientEntry context.
3368 It holds the hostname of the client. Affected file is
3369 lib/silcclient/idlist.h.
3371 * Irssi SILC Client sets the nicknames in nick@hostn format.
3372 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
3373 irssi/src/silc/core/silc-core.c.
3375 The WHOIS printing now also shows both the real nickname and
3376 the formatted nickname so that user knows how to access the
3377 user if there are multiple same nicknames cached. Affected
3378 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
3379 printing formatting too to take the hostname now as a separate
3380 argument. The Affected file is
3381 irssi/src/fe-common/silc/modules-formats.[ch].
3383 * Changed the silc_client_get_clients_local to accept the formatted
3384 nickname as argument. It accepts the real nickname too but the
3385 formatted nickname can be used to find the true entry from
3386 multiple entries. Affected file lib/silcclient/silcapi.h and
3387 lib/silcclient/idlist.c.
3389 * Added nickname_format_parse field to the SilcClientParams.
3390 It is a callback function provided by the application to parse
3391 the nickname out of the formatted nickname string. The library
3392 calls it to get the nickname from the formatted string. Since
3393 the application generally knows better the format of the nickname
3394 string it parses it instead of the library, even though library
3395 encodes the formatted string. If the callback function is not
3396 provided then the library will use the string as is. The
3397 affected file is lib/silcclient/silcapi.h.
3399 * All the nickname strings passed to the client library in
3400 commands are now expected to be formatted nickname strings.
3401 If the command does not support the formatted nickname string
3402 it will assume that the sent string is the actual nickname.
3403 Affected file lib/silcclient/command.c.
3405 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3407 * Added public key authentication support to OPER and SILCOPER
3408 commands in the client library. Affected file is
3409 lib/silcclient/command.c.
3411 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3413 * Changed the get_auth_methdod client operation to be asynchronous.
3414 It can be async if the application resolves the authentication
3415 method from the server during the negotiation. Added new
3416 SilcGetAuthMeth completion callback that the application will
3417 call after resolving the authentication method.
3419 Added function silc_client_request_authentication_method that
3420 the application can use to resolve the authentication method
3421 from the server. Added also SilcConnectionAuthRequest callback
3422 that the library will call after the server has replied. The
3423 application can call this function if it does not know the
3424 current authentication method.
3426 Affected files are lib/silcclient/client.c and
3427 lib/silcclient/silcapi.h.
3429 * The Irssi SILC client now automatically resolves the authentication
3430 method incase any configuration information is not present (and
3431 currently there never is). The affected file is
3432 irssi/src/silc/core/client_ops.c.
3434 * Fixed public key authentication from the client library.
3435 Affected file lib/silcclient/protocol.c. Changed also the
3436 protocol specification about the public key authentication in
3437 the connection authentication protocol. The actual data to be
3438 signed is now computed with a hash function before signing.
3440 * Fixed the public key authentication from the server as well.
3441 Affected file silcd/protocol.c.
3443 * Removed the mlock()'s from the memory allocation routines.
3444 Affected file lib/silcutil/silcmemory.c. The ./configure does
3445 not check anymore for the mlock(). Affected file is
3448 * Fixed USERS command in server to allow the execution of the
3449 command for private and secret channels if the client sending
3450 the command is on the channel. Affected file silcd/command.c.
3452 * Fixed silc_client_get_clients_local to return the clients
3453 count correctly. It could return wrong value. Affected file
3454 lib/silcclient/idlist.c.
3456 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3458 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
3459 types. The assembler optimizations seemed not to like 64-bit
3460 data types. The assmebler optimizations thus are now enabled
3461 also for BSD systems as opposed to only enable them for Linux.
3463 * Do not check for threads at all on BSD systems. Affected
3464 file configure.in.pre.
3466 * Removed -n and -h options from the Irssi SILC Client since
3467 they are not used in silc.
3469 * Fixed the prime generation to assure that the first digit
3470 of the generated random number is not zero since our conversion
3471 routines does not like number strings that starts with zero
3472 digit. If zero digit is seen the random number is regenerated.
3473 This caused some corrupted RSA keys when the zero first digit
3474 was met. Affected file lib/silcmath/silcprimegen.c.
3476 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3478 * Fixed WIN32 configuration in the ./configure script.
3479 Fixed to include xti.h on environments that has it.
3480 Patches by Carsten Ilchmann and andrew.
3482 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3484 * Changed the silc_id_create_client_id to be collision
3485 resistant. It is now assured that there cannot be created
3486 two same client ID's. I suspect that some weird bugs in
3487 the server were actually caused by duplicate Client IDs.
3488 Affected file silcd/serverid.[ch]. A router receiving
3489 new ID now also assures and informs the sending server
3490 if the ID caused collision.
3492 * Changed the silc_id_create_channel_id to also assure that
3493 there are no collisions.
3495 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3497 * Statement about ignoring the Mutual Authentication flag when
3498 performing rekey with PFS was a bit misleading. It is ignored
3499 if it was set in the initial negotiation, it cannot be even
3500 set in the rekey. Fixed in the ke-auth draft. Started the
3501 new versions of the protocol drafts in the doc/.
3503 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3505 * Fixed a bug in silc_client_command_identify_save when saving
3506 new channel information. The channel name was no duplicated
3507 and caused crash on exit. Affected file is
3508 lib/silcclient/command_reply.c.
3510 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3512 * Fixed the getkey command handling in the server. Send just
3513 empty OK reply to the sender if the key could not be fetched
3514 (but everything else was ok, like the key just was not available).
3515 Changed the public key parameter to optional in the protocol
3516 specs so that empty OK reply can be sent. Affected file
3519 Added a message to Irssi SILC client to tell to user if the
3520 server did not return a public key.
3522 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3524 * Fixed a channel key regeneration bug. It registered new
3525 timeout tasks exponentially until all system resources were
3526 used. Affected file silcd/server.c.
3528 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3530 * Added the SILC Document generator to the scripts/silcdoc.
3531 It can be used to generate the Toolkit Reference Manual out
3532 of the source tree. Internally it will also use the RoboDoc
3533 generator now imported in util/robodoc.
3535 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3537 * Added couple of return's in rekey protocol if error orccurred
3538 during the protocol. The execution must be terminated.
3539 Affected file silcd/protocol.c. Also, terminate the protocol
3540 always with timeout.
3542 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3544 * The client's Client ID was created initally from the wrong
3545 nickname (it could have been in format nick@host) in the
3546 silc_server_new_client. Affected file silcd/packet_receive.c
3548 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3550 * Added some SILC_LOG_ERROR's to various error conditions
3551 if client could not be added to ID cache. Affected files
3552 silcd/packet_receive.c and silcd/server.c.
3554 * When client's sock->user_data is freed, NULL also the
3555 client->router and client->connection pointers. Added check
3556 for these pointers being NULL to various places around the
3557 code. Affected file silcd/server.c.
3559 * Added client->data.registered == TRUE checks to various
3560 places around the code to assure that unregistered client's
3561 are not handled when it is not allowed. Affected file
3564 * Added `bool registered' fields to all
3565 silc_idlist_[server|client]_get_* routines to indicate whether
3566 the fetched client needs to be registered or not. Affected
3567 file silcd/idlist.[ch].
3569 * Add your own entry as registered to the ID cache in the
3570 server. Affected file server.c.
3572 * Fixed a bug in silc_server_new_server. The SilcServer was
3573 set as the new server's context instead of SilcServerEntry.
3574 This naturally caused some weird bugs.
3576 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3578 * Do not delete the channel rekey task when adding it
3579 for in silc_server_create_channel_key.
3581 * Changed the silc_server_create_channel_key to return
3582 TRUE or FALSE to indicate the success of the channel key
3585 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3587 * Fixed MSVC++ project files and added missing files to
3588 Makefiles under win32/.
3590 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3592 * Do not add TCP_NODELAY flag if the operating system
3593 does not have it defined. Affected files are
3594 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3596 * Fixed buffer overflow from Irssi SILC Client. Affected
3597 file irssi/src/fe-common/core/themes.c.
3599 * Fixed double free in client library in the file
3600 lib/silcclient/client.c when disconnecting from server.
3602 * Applied double free patch from cras to Irssi SILC client.
3603 Affected files irssi/src/core/[modules/expandos].c
3605 * Fixed the disconnection handling to Irssi SILC Client.
3606 The application must call silc_client_close_connection
3607 in ops->connect client operation in case of failure of
3608 the connection. Affected file is
3609 irssi/src/silc/core/client_ops.c.
3611 * Do not set sock->protocol to NULL in the function
3612 silc_client_close_connection after executing the protocol's
3613 final callback since the sock might not be valid anymore.
3614 Affected file lib/silcclient/client.c.
3616 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3618 * Do not enable SILC_THREADS if the linking with libpthread
3619 did not happen. Affected file configure.in.pre.
3621 * Added notion to protocol specification that server must
3622 verify the sent authentication payload with CMODE when
3623 setting the channel founder key. Implemented it to the
3624 server. Affected file silcd/command.c.
3626 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3628 * Added _EXTRA_DIST SILC distribution variable to the
3629 distributions file. It is used to conditionally add extra
3630 files or directories to the specific distribution. Affected
3631 files ./prepare, Makefile.am.pre and distributions.
3633 Removed the `_' from the start of the distribution names.
3636 * Added README.WIN32 for instructions to compile the Toolkit
3639 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3641 * Fixed a double free in disconnection in the server. Affected
3642 file is silcd/server.c.
3644 * Fixed the lib/silcske/groups.c to work now also with GMP
3645 MP library. The string conversion did not work when using
3646 specific base and the base is indicated in the string as well.
3648 * Created win32/ directory which now includes MSVC++ specific
3649 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3650 It will appear only in the toolkit distribution
3652 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3654 * Changed the key material distribution function in case when
3655 the hash output is too short. The data is now concatenated
3656 a bit differently than it used to. Made the change to the
3657 SKE protocol specification.
3659 * Added better GMP detection to configure.in.pre. A patch
3662 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3664 * Fixed a minor bug in SKE that might cause some problem on
3665 some platforms. Affected file lib/silcske/silcske.c.
3667 * Added the cookie checking for initiator in the SKE. It checks
3668 that the responder returns the sent cookie unmodified. The
3669 affected file is lib/silcske/silcske.c. Added new SKE
3670 error type INVALID_COOKIE that can be sent during the
3671 negotiation. Fixed some memory leaks as well.
3673 * Added the "invalid cookie" error message to Irssi SILC client's
3676 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3678 * Added `task_max' field to the SilcClientParams to indicate
3679 the maximum tasks the scheduler can handle. If set to zero,
3680 default values are used. Affected file lib/silcclient/silcapi.h.
3682 * Fixed memory leaks in silc_client_close_connection. Affected
3683 file lib/silcclient/client.c.
3685 * Added silc_client_del_client_entry to client library to free
3686 all memory of given client entry. Affected file is
3687 lib/silcclient/idlist.[ch].
3689 * Added new functions silc_client_del_channel and
3690 silc_client_del_server to delete channel and server entries.
3691 Affected file lib/silcclient/[silcapi.h/idlist.c].
3693 * Removed silc_client_del_client_by_id from silcapi.h.
3695 * Fixed the INFO command to return the server's own info
3696 correctly when querying by Server ID. Affected file is
3699 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3701 * Removed the non-blocking settings in WIN32 code in the
3702 silc_sock_[read/write] and added SleepEx instead. Affected
3703 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3704 of input data is now checked with FIONREAD and ioctlsocket.
3706 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3708 * Call silc_schedule_task_del_by_context in the
3709 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3710 Affected file lib/silccore/silcprotocol.c.
3712 * Call silc_protocol_cancel for active protocols in the
3713 silc_server_close_connection if the funtion
3714 silc_server_free_sock_user_data has not been called.
3715 Affected file silcd/server.c.
3717 * Generic tasks cannot be deleted using the del_by_fd
3718 task deleting function since generic tasks does not match
3719 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3721 * Added a notion to SILCOPER help file that the SILCOPER works
3722 only on router server, not on normal server.
3724 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3726 * Added for WIN32 support for the new scheduler as well.
3727 Affected file lib/silcutil/win32/silcwin32schedule.c.
3729 * Fixed the SHA1 implementation to work on various platforms.
3731 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3733 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3734 API. It is part of the scheduler now. Everything else is
3735 as previously but some functions has changed their names.
3736 Checkout the lib/silcutil/silcschedule.h for the interface.
3737 Updated all applications to use the new interface. Affected
3738 files are lib/silcutil/silcschedule.[ch].
3740 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3742 * Found a bug in the SKE implementation. The HASH value,
3743 specified by the protocol, was not computed correctly. The
3744 public key of the responder was not added to the computation
3745 even though it is mandatory. Affected file lib/silcske/silcske.c.
3746 This unfortunately causes incompatibilities with older
3747 clients and servers.
3749 * Added WIN32 specific network init and uninit functions:
3750 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3751 the Winsock2. Affected file lib/silcutil/silcnet.h and
3752 lib/silcutil/win32/silcwin32net.c.
3754 * Set the socket always to nonblocking mode on WIN32 after
3755 reading data or writing data. Affected file is
3756 lib/silcutil/win32/silcwin32sockconn.c.
3758 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3760 * Fixed various compilation problems under WIN32. Affected
3761 files lib/silcutil/win32/silcwin32thread.c and
3762 lib/silcutil/win32/silcwin32schedule.c.
3764 * Removed all _internal.h #includes from public header
3765 files. Internal headers must never be included from
3768 Removed also the lib/silcske/payload_internal.h file.
3770 * All include files that may be needed (public and some others
3771 included by the public headers) by application developers are
3772 now copied to the ./includes directory. It does not copy any
3773 internal headers. Affected file Makefile.defines.pre and all
3774 Makefile.am's under lib/ and subdirs.
3776 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3778 * Do not change the ~/.silc directory's permissions automatically.
3779 Affected file irssi/src/silc/core/clientutil.c.
3781 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3783 * Do not cancel the protocol in silc_server_close_connection
3784 it might cause recursion. Now cancelled in the function
3785 silc_server_free_sock_user_data. Affected file silcd/server.c.
3787 * Fixed the silc_server_remove_clients_by_server to regenerate
3788 the channel keys correctly finally. Added also new function
3789 silc_server_remove_clients_channels to actually do it.
3790 Affected file silcd/server.c.
3792 * Fixed the silc_server_new_channel to not crash by giving
3793 wrong router to the new channel. Affected file is
3794 silcd/packet_receive.c.
3796 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3798 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3799 which is given as argument to the silc_client_alloc now.
3800 It can be used to configure the client and set various parameters
3801 that affect the function of the client.
3803 * The USERS command in server did not check whether the channel
3804 is private or secret. Affected file silcd/command.c.
3806 * Added new argument to the USERS command in protocol specification.
3807 The USERS command now can take the channel name as argument
3808 as well. Added support for this in client and server and
3809 updated the protocol specs.
3811 * Completed the GETKEY command in client. It can be now used
3812 to fetch also servers public key not only some clients.
3813 Affected files lib/silcclient/command[_reply].c.
3815 * Added silc_client_get_server to return server entry by the
3816 server name. Affected files lib/silcclient/silcapi.h and
3819 * Redefined the IDENTIFY command in protocol specification to be
3820 more generic. It now can be used to query information about
3821 any entity in the SILC Network, including clients, servers and
3822 channels. The query may be based either the entity's name
3823 or the ID. Added support for this in both client and server.
3825 Affected files silcd/command.c and lib/silcclient/command.c
3826 and command_reply.c.
3828 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3829 the _from_client and _from_server functions. Affected file
3832 * Added silc_client_get_channel_by_id_resolve to the file
3833 lib/silcclient/silcapi.h to resolve channel information by
3834 its ID. Added also silc_client_get_channel_by_id that
3835 does not resolve it from the server.
3837 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3839 * Added SilcServerEntry context into the client library
3840 to represent one server. The INFO command now allocates
3841 these to save the resolved server info. For now on the
3842 client library will also keep information about servers,
3843 connected and resolved with INFO.
3845 The INFO command now allocates the SilcServerEntry context
3846 and saves the server info there. The COMMAND_REPLY in
3847 the INFO now returns the parameters to application in
3848 same order as defined in the protocol specification.
3850 The entries are cached in the client->server_cache.
3852 * The INFO command is now issued after received the Client ID
3853 from the server. Affected file lib/silcclient/client.c.
3855 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3856 to the application as the mode changer might be server.
3857 It is guaranteed that NULL is not returned anymore to the
3858 application. Affected file lib/silcclient/client_notify.c.
3860 The ID Type is now also passed to the application so that
3861 it can check whether the returned entry is SilcClientEntry
3864 Added new function silc_client_get_server_by_id to return
3865 the server entry by ID. Affected files are the
3866 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3868 * Do not create the channel in the Irssi SILC Client when issuing
3869 the JOIN command but when received the sucessful JOIN command
3870 reply. Otherwise the channel might get created even though we
3871 could not join it. The Affected file is
3872 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3874 * Fixed a channel joining bug in router. The router must also
3875 check the channel modes, invite and ban lists etc. when serving
3876 the JOIN command sent by normal server. Affected file is
3877 silcd/command.c. The router now resolves the client's
3878 information from the server who sent the JOIN command if it
3879 does not know it, and processes the JOIN command only after
3882 * Changed the SilcCommandCb to take new argument; void *context2.
3883 Affected file lib/silccore/silccommand.h
3885 The second argument in the command callbacks in the server now
3886 includes the SilcServerCommandReplyContext if the command was
3887 called as pending command callback from the command reply.
3888 Otherwise it is NULL. When called as pending the status of the
3889 command reply will be checked and if it was erronous the
3890 error will be sent to the original sender of the command.
3891 This way the client always receives the error messages even
3892 though the server was actually the one who received the error
3893 when it resent the command to router, for example. Affected
3894 files silcd/command[_reply].[ch].
3896 * Fixed sending WHOWAS command's error message to client if
3897 the requested client could not be found. It was missing.
3900 * Changed the CMODE and CUMODE commands reply arguments in the
3901 protocol specification. The Channel ID is now sent in both
3902 of the commands to identify the channel. Implemented this
3903 new feature to the client and server. Affected files
3904 lib/silcclient/command_reply.c and silcd/command.c.
3906 * Made better checks for invite and ban lists in the JOIN
3907 command in server. Affected file silcd/command.c.
3909 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3911 * The server now performs the incoming host IP/DNS lookup
3912 using the silc_socket_host_lookup and thus does not block
3913 the server anymore. Affected file silcd/server.c.
3915 * Completed the multi-thread support for SILC Scheduler in
3916 the lib/silcutil/silcschedule.c.
3918 * Fixed the configure.in.pre to detect the pthread correctly
3921 * Fixed a deadlock in silc_task_queue_wakeup in the file
3922 lib/silcutil/silctask.c.
3924 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3926 * Added new function silc_schedule_wakeup that is used in
3927 multi-threaded environment to wakeup the main thread's
3928 schduler. It needs to be used when a thread adds a new task
3929 or removes a task from task queues. After waking up, the
3930 scheduler will detect the task queue changes. If threads
3931 support is not compiled in this function has no effect.
3932 Implemented the wakeup mechanism to both Unix and WIN32
3933 systems. Affected files are lib/silcutil/silcschedule.[ch],
3934 lib/silcutil/unix/silcunixschedule.c and the
3935 lib/silcutil/win32/silcwin32schedule.c.
3937 * Added new function silc_task_queue_wakeup to wakeup the
3938 scheduler by the specified task queue. Affected file
3939 lib/silcutil/silctask.[ch].
3941 * The silc_socket_host_lookup_start now wakes up the scheduler
3942 after adding the timeout task. Affected file is
3943 lib/silcutil/silcsockconn.c.
3945 * The silc_socket_host_lookup is synchronous now if the threads
3946 support is not compiled in. However, the callback is still
3947 called asyncronously through the scheduler, anyway. Affected
3948 file lib/silcutil/silcsockconn.c.
3950 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3952 * Added new function silc_socket_host_lookup to perform
3953 asynchronous IP and FQDN lookups for the socket connection.
3954 Affected files lib/silcutil/silcsockconn.[ch].
3956 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3958 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3959 that may or may not compile the mutex support in.
3961 Changed the silc_mutex_alloc interface. It allocates the
3962 mutex now to the sent pointer and returns TRUE or FALSE.
3964 Affected file lib/silcutil/silcmutex.h.
3966 * Wrote the SILC Task Queue interface to support multi-threads.
3967 Affected file lib/silcutil/silctask.[ch].
3969 * Wrote the SILC Scheduler to support multi-threads. Affected
3970 file lib/silcutil/silcschedule.c.
3972 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3974 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3975 in lib/silcutil/win32/.
3977 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3979 * Defined SILC Mutex API and SILC Thread API and implemented
3980 them for Unix. Affected files are
3981 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3982 lib/silcutil/unix/silcunixmutex.c and
3983 lib/silcutil/unix/silcunixthread.c.
3985 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3987 * Fixed the silc_server_remove_clients_by_server's channel
3988 key re-generation. The hash table handling was incorrect
3989 and would not work with many channels. Affected file is
3992 * Fixed some memory leaks around the server code.
3994 * Rewrote the silc_server_get_users_on_channel to support IPv6
3995 based Client ID's. Affected file silcd/server.c.
3997 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3998 specification. However, a separate document must be written
3999 to define the detailed signing procedure and the payload
4000 associated with the flag. Defined the flag to the
4001 lib/silccore/silcchannel.h as well.
4003 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4005 * Changed the dynamic tables to static size tables in the
4006 lib/silccrypt/silchmac.c.
4008 * Removed GCC dependencies from the code. A patch by cras.
4010 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4012 * Do not show the error "Error receiving packet bla bla"
4013 in server if it really was not an error (-2 means that reading
4014 is pending). Affected file silcd/server.c.
4016 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4018 * Fixed a possible crash in silc_server_remove_clients_by_server
4019 in silcd/server.c. Fixed there also some memory leaks.
4021 * Fixed the silc_idlist_replace_client_id. It could replace
4022 wrong key in the hash table. Affected file silcd/idlist.c.
4024 * Do not check whether there are global users on the channel
4025 if the channel->global_users is FALSE. Affected functions
4026 silc_server_remove_from_one_channel and
4027 silc_server_remove_from_channels in silcd/server.c. Also,
4028 do not check if the removed client is local as we can be
4029 sure that global client was not removed from the channel
4030 and checking for global users is not needed.
4032 * The silc_server_remove_clients_by_server now re-generates
4033 the channel keys correctly for those channels that had
4034 clients removed from them. Affected file silcd/server.c.
4036 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4038 * Found the reason of random crashes in the server. We weren't
4039 ignoring the SIGPIPE signal (which can be sent in write())
4040 and it crashed the server. Affected file silcd/silcd.c.
4042 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4044 * Assure that sock->user_data is not NULL in the function
4045 silc_server_packet_send in silcd/packet_send.c.
4047 * Disconnect the remote connection if it could not be added
4048 to any ID lists in the server. The affected file is
4051 * Check in silc_server_packet_send[_real/dest] that the
4052 socket is not disconnecting and ignore the data if it is.
4053 Affected file silcd/packet_send.c.
4055 * Define inline to __inline on native WIN32 compilation.
4056 Affected file includes/silcwin32.h.
4058 * Added some explicit type casts for inline code since MSVC
4059 require them. Affected files lib/silcutil/silcbuffer.h,
4060 lib/trq/silcdlist.h and lib/trq/silclist.h.
4062 * Print warning in log files from now on if the packet
4063 decryption fails. Affected file silcd/server.c.
4065 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4067 * Changed the `say' client operation's interface to accept
4068 new `type' argument to indicate the type of the message sent
4069 by the library. The application may filter the library's
4070 messages according the type. The affected file is the
4071 lib/silcclient/silcapi.h.
4073 * Added two new functions to lib/silcclient/silcapi.h:
4074 silc_client_del_client and silc_client_del_client_by_id.
4075 Affected file lib/silcclient/idlist.c.
4077 * Moved the clientincludes.h from includes/ to silc/ and
4078 serverincludes.h from includes/ to silcd/.
4080 * The modes for the CMODE and CUMODE are now passed as
4081 uint32 for application with COMMAND_REPLY. The affected
4082 file is lib/silcclient/command_reply.c.
4084 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4086 * /WHOIS without arguments shows client's own information.
4087 Affected file lib/silcclient/command.c.
4089 * Changed PING to not accept any arguments. The specs
4090 says that client can ping only the connected server so
4091 requiring an argument is not needed. Affected file is
4092 lib/silcclient/command.c.
4094 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4096 * Fixed a fatal bug in private message sending and reception
4097 encryption and decryption when using private message keys.
4098 The implementation was incorrect and did not follow the
4099 specification. It causd that some of the message were
4100 lost since it did not use the sending and receiving keys
4101 as the protocol suggests. This has been fixed and will cause
4102 incompatibilities with older clients when sending private
4103 message encrypted with private message keys. Affected files
4104 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
4105 and various other in Irssi SILC Client.
4107 Added `responder' boolean argument to the functions
4108 silc_client_add_private_message_key[_ske] to indicate when
4109 the key is added as responder or initiator of the key
4112 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4114 * Removed the silc_ske_check_version function and created
4115 a SilcSKECheckVersion callback. Added also a function
4116 silc_ske_set_callbacks that is now used to set all SKE
4117 callbacks. The callback functions are not given to
4118 the SKE functions anymore, but this function is used to
4121 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
4123 * Added `silc_version' argument to the silc_client_alloc
4124 to define the version of the application for the library.
4125 The library will use the version string to compare it
4126 against the remote host's (usually a server) version
4127 string. Affected file lib/silcclient/silcapi.h
4129 * Added the KE protocol context to Key Agreement context
4130 in client library so that we can abort the SKE if it
4131 is in process when we get timeout. Affected file is
4132 lib/silcclient/client_keyagr.c.
4134 * Do not resolve the client ID forever if it returns in the
4135 first time that such client does not exist. This was done
4136 for example with private message. Affected file is
4137 lib/silcclient/client_prvmsg.c.
4139 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4141 * Do not add regex.h for WIN32. The affected file
4142 includes/silcincludes.h.
4144 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
4145 not work yet 100%. It generates the DLL's automatically
4146 when compiling with --with-win32 under cygwin.
4148 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4150 * lib/contrib/regex.c is not compiled on WIN32.
4152 * Added silc_net_get_socket_opt function to the
4153 lib/silcutil/silcnet.h.
4155 * Added includes/silcwin32.h for WIN32 specific includes
4158 * Do not use ptime structure or any of the posix process
4159 functions on WIN32 in lib/silccrypt/silrng.c.
4161 * Added silc_gettimeofday to provide generic function
4162 for struct timeval on all platforms. Added the function
4163 to lib/silcutil/silcutil.h.
4165 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4167 * Moved the lib/silccore/silcsockconn.[ch] to the utility
4168 library as they clearly belong there. As a plus side we
4169 can make the actual socket connection routines platform
4172 Added also new generic function silc_socket_read and
4173 silc_socket_write (that used to be silc_packet_[read/write].
4174 The implementation of these are platform specific.
4176 * Added WIN32 specific routines of silc_socket_[read/write]
4177 to lib/silcutil/win32/silcwin32sockconn.c.
4179 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4181 * Added preliminary support for native WIN32 compilation under
4182 cygwin (using the -mno-cygwin option for GCC) to the
4183 ./configure.in.pre. The --with-win32 now prepares the
4184 compilation for native WIN32.
4186 * Rewrote the SILC Scheduler interface in the file
4187 lib/silcutil/silcschedule.h. The scheduler is now context
4188 based and does not have anymore any global static scheduler.
4189 Moved the Unix scheduler to the lib/silcutil/unix/ directory
4190 and created lib/silcutil/win32 directory for WIN32 based
4193 * Added Unix specific network routines to the
4194 lib/silcutil/unix/silcunixnet.c and the old
4195 lib/silcutil/silcnet.c includes now only generic routines.
4197 Added WIN32 specific network routines to the
4198 lib/silcutil/win32/silcwin32net.c.
4200 * Added Unix specific utility functions from the
4201 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
4203 * Added WIN32 SILC Scheduler to the file
4204 lib/silcutil/win32/silcwin32schedule.c. The code is of course
4207 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4209 * Do not handle JOIN notify in the server if the target client
4210 is not registered (idata->registered == FALSE). The affected
4211 file is silcd/packet_receive.c.
4213 * Update the nickrec->founder in event_cumode in the Irssi SILC
4214 client. Affected file irssi/src/silc/core/silc-channels.c.
4216 * Fixed the CUMODE_CHANGE notify handling in the server when
4217 server and router are announcing their clients on channels.
4218 Now the mode changes are saved and notified correctly. The
4219 affected file is /silcd/packet_receive.c.
4221 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
4222 They really did not replace the cache entry in the ID Cache.
4223 Now they do that. Affected file silcd/idlist.c.
4225 * Fixed the KICK notify handling in the Irssi SILC client to
4226 update the channel records so that the kicked client does not
4227 appear to be on the channel. The affected file is
4228 irssi/src/silc/core/silc-channels.c.
4230 * Always update the conn->current_channel when executing command
4231 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
4233 * Fixed the KILL notify handling in Irssi SILC client to remove
4234 the killed client on all channels.
4236 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4238 * Fixed the silc_parse_command_line to remove extra spaces
4239 from the start and end of the arguments. Affected file is
4240 lib/silcutil/silcutil.c.
4242 * Cancel and free any active protocol in the function
4243 silc_server_close_connection. Affected file silcd/server.c.
4245 * Cancel and free any active protocol in the function
4246 silc_client_close_connction. Affected file is
4247 lib/silcclient/client.c.
4249 * Do not execute the KILL command for clients that are in
4250 history (ie. they are not in the network). Affected file is
4253 * Fixed KILL notify handling, client does not crash anymore.
4254 Affected file irssi/src/silc/core/silc-channels.c.
4256 * Reduced the default packet buffer size from 2048 to 1024 in
4257 lib/silccore/silcpacket.c.
4259 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
4260 counter to the SKE context that is incresed when the SKE library
4261 performs async operation outside the library. If the outside
4262 process frees the SKE context and FREED status will be set
4263 and the library will detect after the sync operation that the
4264 libary is freed. The affected files are
4265 lib/silcske/silcske[_status].[ch].
4267 * Resolve the client entry information in the function
4268 silc_client_channel_message to assure that NULL pointer is not
4269 passed as client entry to the application. */
4271 * Fixed the task timeout calculation to assure that there is
4272 never negative timeouts. The affected file is
4273 lib/silcutil/silcschedule.c.
4275 * Fixed the channel user mode notification sending in server.
4276 It was sent point-to-point to the router (or to server by router)
4277 but it needs to be destined to a channel. The routines now
4278 supports sending the channel user mode notifys to the channels
4279 when announcing clients and channels. Affected files are
4280 silcd/server.c and silcd/packet_receive.c.
4282 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
4283 It did not actually replace the old channel entry in the cache.
4284 Affected file lib/silcclient/client_notify.c.
4286 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4288 * Fixed a possible crash in silc_packet_send_prepare. It now
4289 assures always that there is enough space in the buffer and
4290 at the tail area of the buffer (for MAC).
4292 Fixed the inbound buffer reallocation in silc_packet_read.
4293 It was old code and did not handle the reallocation correctly.
4296 The affected file is lib/silccore/silcpacket.c.
4298 * Fixed buffer overflow in silc_parse_nickname in the file
4299 lib/silcutil/silcutil.c.
4301 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4303 * make install generates new server keys only if there is not
4306 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4308 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
4309 Added check that if the NOREPLY is set then we will not send
4310 the away message. This avoids infinite loop of away messages
4311 if both clients are away. The affected file is
4312 lib/silcclient/client_prvmsg.c.
4314 * Fixed client crash if /NICK was given without arguments.
4315 Affected file lib/silcclient/command.c.
4317 * Server does not send the invite list in INVITE command back
4318 to the client if the list was not altered. Added this notion
4319 to the protocol spec as well. Affected file silcd/command.c.
4321 Fixed possible crash in INVITE command by checking the
4322 value of silc_server_get_client_route command.
4324 * Fixed the INVITE notify type handling. The arguments are now
4325 taken in correct order and client does not crash. The affected
4326 file is irssi/src/silc/core/silc-channels.c.
4328 Removed the "Inviting xxx to channel" message from the
4329 client library away and let the application handle it.
4330 Affected file lib/silcclient/command.c. Added that message
4331 to Irssi SILC client's message formats.
4333 * Fixed CMODE command crash in client. It now checks the
4334 amount of arguments correctly and does not crash. The affected
4335 file is lib/silcclient/command.c.
4337 * Do not create new channel automatically in silc_channels_join
4338 but check whether the channel by that name already exists.
4339 Affected file irssi/silc/core/silc-channels.c.
4341 * Do not send the SERVER_SIGNOFF to router if the disconnected
4342 entity was the router. Affected file silcd/server.c.
4344 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
4345 SILC client as it was missing from there.
4347 Added the handling of the KICK notify to the Irssi SILC client
4348 as it was missing. Added "you have been kicked" message to
4349 Irssi SILC client's message modules formats.
4351 Added the handing of the KILL notify to the Irssi SILC client
4352 as it was missing. Added the kill message module formats
4355 The affected file is irssi/src/silc/core/silc-channels.c.
4357 * The router did not save the channel mode the server announced.
4358 Affected file silcd/packet_receive.c.
4360 * Fixed a possible crash in INFO command in server. If the
4361 server did not provide the server info it crashed. Affected
4362 file silcd/command.c.
4364 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4366 * Fixed the GETKEY command in the server to check also the
4367 global list. Otherwise the GETKEY would not work correctly
4368 in normal SILC server. Affected file silcd/command.c.
4370 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4372 * Fixed GETKEY crash, it crashed if the command did not succseed.
4374 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4376 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
4377 is now real and not just an macro interface to GMP.
4379 Removed the entire GMP from the source tree and imported new
4380 NSS MPI library instead. Reason for removing GMP is that it is
4381 extremely large and compiles extremely slow. The NSS MPI
4382 is only a few files and compiles in less than 10 seconds.
4383 The speed is also about the same as GMP. The MPI is imported
4384 to lib/silcmath/mpi.
4386 If the system has GMP installed we will still use the GMP.
4387 If it is not then the NSS MPI will be compiled.
4389 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4391 * Merged a long nickname (127 characters long) crash bugfix from
4392 Irssi CVS tree. Affected file irssi/src/core/misc.c.
4394 * Merged a freed memory reference bugfix from Irssi CVS tree.
4395 Affected file irssi/src/core/commands.c.
4397 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4399 * Added the server's public key sving and verification to the
4400 server when performing the SKE. This was missing and the
4401 remote server's (or router's) public key was accepted without
4402 checking whether we have it previously or trust it at all.
4403 Affected file silcd/protocol.c.
4405 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4407 * Check in the silc_server_timeout_remote if protocol is active
4408 and make sure that the protocol's final callback is called so
4409 that all memory if freed. Affected file silcd/server.c.
4411 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4413 * silc_server_whois_send_reply crashed the server if the nickname
4414 was 127 characters long. Affected file silcd/command.c.
4416 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4418 * Added sanity check to the silc_server_new_client. If the hostname
4419 is provided inside username then check that the provided hostname
4420 really is the same as the resolved one. If the hostname was not
4421 resolved then check it from the public key. Affected file is
4422 silcd/packet_receive.c.
4424 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
4425 if the server disconnected us and the connection is not valid
4426 anymore. Affected file irssi/src/silc/core/silc-channels.c.
4428 * Moved the silc_client_[chmode|chumode|chumode_char] away from
4429 the library to the lib/silcutil/silcutil.[ch].
4431 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4433 * Close log file after open. Affected file
4434 lib/silcutil/silclog.c.
4436 * Check whether sock == NULL in silc_client_send_packet and return
4437 if it is. Affected file lib/silcclient/silcclient.c.
4439 * Check rec->entry == NULL in the Irssi SILC Client before
4440 sending the channel message. Affecte file is
4441 irssi/src/silc/core/silc-servers.c.
4443 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4445 * Merged a splitted window bugfix from Irssi CVS tree. The
4446 affected file is irssi/src/fe-text/textbuffer-view.c.
4448 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
4449 It did not print nickname.
4451 * Improved the distributions system a bit.
4453 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4455 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
4456 irssi/src/fe-text/gui-window.c.
4458 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
4459 to in-active server. The affected file is
4460 irssi/src/silc/core/client_ops.c.
4462 * Resolve the client in USERS command reply if the entry does
4463 not have username resolved. The affected file is
4464 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
4465 command to WHOIS command to really resolve stuff. The USERS
4466 is not used any more in any critical section so WHOIS can
4467 be used even though it might be slower than IDENTIFY.
4469 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
4472 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4474 * Changed the protocol API a bit more consistent in the
4475 lib/silccore/silcprotocol.[ch].
4477 * Changed the following headers to ROBODoc format:
4479 lib/silccore/silcpayload.h
4480 lib/silccore/silcprotocol.h
4481 lib/silccore/silcsockconn.h
4483 All core library headers are now formatted.
4485 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4487 * Fixed a bug in Irssi SILC client; do not show that you are
4488 server/router operator if you really are not. Affected file is
4489 irssi/src/silc/core/client_ops.c.
4491 * Renamed silc_command_free_payload to silc_command_payload_free.
4492 Affected file lib/silccore/silccommand.h
4494 * Added silcmath.h to include the prototoypes of various routines
4495 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
4498 * Changed the following headers to ROBODoc format:
4500 lib/silccore/silcchannel.h
4501 lib/silccore/silccommand.h
4502 lib/silccore/silcid.h
4503 lib/silccore/silcidcache.h
4504 lib/silccore/silcmode.h
4505 lib/silccore/silcnotify.h
4506 lib/silccore/silcpacket.h
4507 lib/silcmath/silcmath.h
4509 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4511 * Added checking to the server code not to start the server if
4512 ciphers and stuff are not configured properly. Affected files
4513 silcd/serverconfig.[h] and silcd/server.c.
4515 * Changed the layout of the header files of the public interfaces
4516 in the SILC libraries. The new layout supports ROBODoc
4517 documentation tool (and some others) so that it is easy to create
4518 a library reference manual. All the other headers and source
4519 code must still follow the CodingStyle document. Also source
4520 code must not include these ROBODoc stuffs, only the headers.
4521 Furthermore, all public interface headers must now be named
4522 by using `silc' prefix, example: silcapi.h, silccipher.h.
4523 Some files were renamed due to this. All the other headers
4524 must not be used as public interfaces. I will update the
4525 CodingStyle document later. Changed following headers, so far:
4527 lib/silcclient/silcapi.h
4528 lib/silccore/silcauth.h
4529 lib/silccore/silcprivate.h
4530 lib/silccrypt/silcdh.h
4532 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4536 * Removed silc_client_packet_send_flush from the client library
4537 as it is not needed. Affected file lib/silcclient/client.[ch].
4539 * Added printing of message of unresolved authentication method
4540 to the Irssi SILC client. Added it to the module formats.
4541 Removed the same message from the client library.
4543 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4545 * Added new distribution feature, DISTLABEL. Every distribution
4546 can define own preprocessor label that can be used in the
4547 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
4548 file distributions, acconfig.h.pre and prepare.
4550 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4552 * Added Makefile.defines_int to include the actual definitions
4553 for Makefile.defines.in. Tested the new distribution system,
4554 created distributions and tested installation.
4556 * Added AWAY message printing to the Irssi SILC client. Added
4557 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
4559 * Added SCONNECT command to call the SILC's CONNECT command.
4560 Cannot use CONNECT directly since Irssi uses that internally.
4561 Affected file irssi/src/silc/core/silc-servers.c.
4563 Added ACTION local command. It is same as ME command but takes
4564 the channel as mandatory argument.
4566 Rewrote some of the Irssi's help files to suite for SILC
4569 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4571 * Added Makefile.defines[.in] that should for now on be included
4572 in all Makefile.am file in the source tree. That file includes
4573 all common compilation definitions for SILC source tree.
4575 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4577 * Minor changes to the ./prepare script to change the package
4578 name according the distribution name to the configure.in.
4580 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4582 * Created new distribution system. Added file `distributions'
4583 that defines all the distributions that can be created out of
4584 the SILC source tree. The ./prepare script now reads that
4585 file to determine how to prepare the distributions. The
4586 first argument to the ./prepare is the name of the distribution
4587 and second is the version of the distribution. If given
4588 without arguments it creates the default (toolkit) distribution
4589 with the default version (defined in ./prepare).
4591 All Makefile.am files that are subject to the distributions
4592 are now named as Makefile.am.pre. These are ./Makefile.am
4593 and lib/Makefile.am. Others may be changed later.
4595 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4597 * Added invite list, ban list, some key management and connection
4598 error message printing to module formats in the Irssi SILC client.
4600 * Added new silc_client_set_away_message to set the away message
4601 that is back to the person who sent private message. The
4602 affected file lib/silcclient/silcapi.h and the
4603 lib/silcclient/client_prvmsg.c.
4605 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4607 * Fixed the private message sending in the Irssi SILC client,
4608 added local command KEY to the Irssi SILC client.
4610 Added key management and key agreement message formats to the
4611 irssi/src/fe-common/silc/module-formats.[ch].
4613 Added USERS (alias WHO) printing, server/router operator
4614 indication and LIST command printing to the module formats.
4616 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4618 * Fixed channel joining notify handling, cumode notify handling
4619 from Irssi SILC client.
4621 * Added SILC specific module-formats to the Irssi SILC client so
4622 that SILC specific message hilighting, colors etc is possible.
4623 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4625 Added channel mode, channel user mode, actions, notices,
4626 whois and whowas printing to the the module-formats.c.
4628 * Fixed a bug in channel deletion in the server. The channel
4629 is not left to the cache even if the channel founder auth mode
4630 is set when there are no users anymore on the channel. Affected
4631 file silcd/server.c.
4633 * The silc_net_localhost now resolves the entire hostname including
4634 the domain name. Affected file lib/silcutil/silcnet.c.
4636 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4638 * Changed the ask_passphrase client operation to be ascynchronous.
4639 It has now a completion callback and a context that the
4640 application must call after it has got the passphrase from
4641 the user. Affected files lib/silcclient/silcapi.h,
4642 lib/silcclient/protocol.c, lib/silcclient/command.c and
4645 Added SilcAskPassphrase callback that the application calls
4646 to deliver the passphrase to the library.
4648 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4649 The public key verification and especially a certificate
4650 verification is asynchronous procedure.
4652 Added new SILC_SKE_STATUS_PENDING status to indicate the
4653 request is pending and a callback will be called to finalize
4656 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4657 indicate that remote end did not send its public key (or
4658 certificate), even though we require it. Added check for this
4659 condition in the SKE. This was a security bug, now fixed.
4661 Defined new SilcSKEVerifyCbCompletion callback that is called
4662 when the verification process is completed.
4664 The affected files lib/silcske/silcske_status.h and
4665 lib/silcske/silcske.[ch].
4667 * Changed the verify_public_key client operation to be async
4668 as well. Defined SilcVerifyPublicKey callback that is used to
4669 indicate the success of the public key verification process.
4671 Changed the server and client to use the new async client
4674 * Changed the Irssi SILC client's internal scheduler to be called
4675 twice as many times as it used to be. As a result the client
4676 should be a bit faster now. Affected file is
4677 irssi/src/silc/core/silc-core.c.
4679 * Added support to Irssi SILC client of asynchronous public key
4680 verification and passphrase inquiry. Affected file is
4681 irssi/src/silc/core/silc-core.c.
4683 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4685 * Do not say "You have left channel %s" in client library.
4686 Moved it to the application. Affected files are
4687 lib/silcclient/command.c and silc/client_ops.c.
4689 * Fixed silc_client_get_clients. Command context was not
4690 duplicated and was freed memory in the callback. Affected
4691 file lib/silcclient/idlist.c.
4693 * Do not say "you are now talking..." on JOIN command in the
4694 client library. The appliation must handle it.
4696 * Do not say ".. changed topic to" in command reply in the
4697 client libary. The application must handle it.
4699 * Fixed TOPIC command sending in the client library.
4701 * Fixed a memory leak in silc_client_command_free in the file
4702 lib/silcclient/command.c.
4704 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4706 * Imported a modified version of Irssi client to the source tree.
4707 The Irssi will be used to create a new client called
4708 Irssi SILC. Imported to irssi/.
4710 Added silc_core_init_finish function to the Irssi. Affected
4711 file irssi/configure.in.
4713 A lot changes in the Makefile.ams around the irssi tree.
4715 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4717 * Do not rehash if the new size is same as the old size of the
4718 hash table, in the silc_hash_table_rehash*. The affected file
4719 lib/silcutil/silchashtable.c.
4721 * Replaced hash_table_del_by_context calls from the server
4722 (when channel->user_list and client->channels) to the
4723 hash_table_del as it is sufficient and faster.
4725 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4727 * Added silc_hash_table_list, silc_hash_table_get and the
4728 SilcHashTableList structure to provide an alternative way to
4729 traverse the hash table. The affected files are
4730 lib/silcutil/silchashtable.[ch].
4732 * Changed the server's idlist routines to use the hash table
4733 routines to optimize the code.
4735 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4737 * Replaced the client entry's `channel' list and channel entry's
4738 `user_list' list to hash tables for optimized lookup. Changed
4739 the code to use the hash table interface around the code.
4740 Affected file lib/silcd/idlist.[ch].
4742 * Added `auto_rehash' boolean argument to the function
4743 silc_hash_table_alloc to indicate whether the hash table should
4744 auto-rehash when it thinks is appropriate time. It will
4745 increase the hash table size if the there is twice as much
4746 entries in the table than the size of the table, and will
4747 decrease the size if there are twice as less entries than
4748 the size of the table.
4750 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4752 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4754 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4756 * silc_idcache_purge_by_context deletes the entry now by context
4757 as it is supposed to do. Affected file lib/silccore/idcache.c.
4759 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4760 client is not anymore valid (WHOWAS givens the info) and not
4761 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4763 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4765 * Removed the `data' and `data_len' arguments from the ID Cache
4766 interfaces and added `name' argument. ID Cache does not handle
4767 anymore the binary data only a names associated with given ID.
4769 * When hashing a Client ID with silc_hash_id the entire ID is
4770 not hashed anymore, instead only the hash of the Client ID is
4771 hashed. This way we can access the Client ID from the cache
4772 with Client ID but with the hash of the ID (which is a hash of
4773 the nickname) as well without any difference in performance.
4775 Added also silc_idcache_find_by_id_one_ext to do one on one
4776 searching when we have the actual ID. Added also function
4777 silc_hash_client_id_compare. The affected files are
4778 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4780 * When hashing the name associated with a ID it is always done
4781 in lowercase. This way we can access the cache without worrying
4782 about case-sensitivity, even though, for example nicknames are
4785 * Fixed a bug in server with channel message sending. It put
4786 wrong ID type as destination ID. The affected file
4787 silcd/packet_send.c.
4789 * silc_idcache_del_by_context now deletes from all hash tables
4790 by context. Affected file lib/silccore/idcache.c.
4792 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4794 * Changed the client library to use the new ID Cache interface.
4795 Changes around the source tree.
4797 * Added silc_hash_table_rehash_ext to rehash with specific
4798 hash function. Affected file lib/silcutil/silchashtable.[ch].
4800 * Added silc_hash_string_compare to compare two strings in the
4801 hash table. Affected file lib/silcutil/silcutil.[ch].
4803 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4805 * Added new function silc_idcache_del_by_context into the
4806 lib/silccore/idcache.[ch].
4808 * Changed the server's ID list routines to use the new ID Cache
4809 interface. Changes around the source tree.
4811 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4813 * Added silc_hash_table_del[_by_context]_ext functions in to the
4814 lib/silcutil/silchashtable.[ch].
4816 Removed silc_hash_table_find_all* routines and added new
4817 silc_hash_table_find_foreach to replace them.
4819 Added silc_hash_table_replace_ext function as extended
4820 replacing function. Separated the simple hash table interface
4821 from the extended hash table interface in the file
4822 lib/silcutil/silchashtable.h.
4824 * Fixed minor bugs and changed it to use some of the new
4825 hash table functions in lib/silccore/idcache.c
4827 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4829 * Added new function silc_hash_table_find_all to return all keys
4830 in the hash table by the specified key. As the hash table is
4831 collision resistant it also makes it possible to have several
4832 duplicate keys in the hash table. This function may be used to
4833 find all of the keys from the hash.
4835 Added user_context arguments to the SilcHashFunction,
4836 SilcHashCompare and SilcHashDestructor to deliver user specified
4839 Added new fuctions silc_hash_table_find[_all]_ext to do
4840 extended lookup with specified hash and compare functions and
4841 specified user contexts.
4843 Added new function silc_hash_table_add_ext to add the key
4844 with specified hash function and user context.
4846 Added new function silc_hash_table_foreach to traverse all
4847 entrys in the hash table. Added SilcHashForeach callback
4850 Added new function silc_hash_table_del_by_context to delete
4851 the entry only if the context associated with the key matches.
4853 Affected files are lib/silcutil/silchashtable.[ch].
4855 * Removed silc_hash_[server/client/channel]_id and added just
4856 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4857 silc_hash_id_compare to compare two ID's using as the hash table
4858 comparison function. Added also silc_hash_data to hash
4859 binary data and silc_hash_data_compare to compare it.
4861 * Removed silc_idlist_find_client_by_hash as it is not needed
4862 anymore. Affected file silcd/idlist.[ch].
4864 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4865 to use internally the SilcHashTable. The new ID Cache is a lot
4866 faster than the old one. Some of the ID Cache interface was also
4867 rewritten and obsolete and stupid functions were removed.
4869 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4871 * Added entry_count field to the SilcHashTable to keep the number
4872 of the entries in the table. Implemented the function
4873 silc_hash_table_rehash. Added new function
4874 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4876 Fixed a minor bug in silc_hash_table_free.
4878 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4879 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4880 into the lib/silcutil/silcutil.[ch].
4882 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4884 * Implemented a collision resistant hash table into the
4885 lib/silcutil/silchashtable[ch]. See the header and the source
4886 for the SilcHashTable API.
4888 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4890 * Merged dotconf version 1.0.2 into lib/dotconf.
4892 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4894 * Do not compile anything in lib/silcsim/* if the SIM support
4895 is not enabled. The tree should now compile without problems
4898 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4900 * Compiled the SILC under cygwin. Compiled and tested briefly
4901 without problems. More tests needed. The SIMs didn't compile
4904 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4906 * Fixed possible crash in silc_get_username in the
4907 lib/silcutil/silcutil.c.
4909 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4911 * Fixed a va_arg in silc/client_ops.c.
4913 * Oops, RC5 routines were named AES and caused some problems
4914 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4916 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4918 * Added new SilcIDIP structure into the lib/silccore/id.h and
4919 replaced the old `ip' fields from all SILC ID's to that type.
4920 This is a step towards IPv6 support.
4922 The silc_id_get_len takes now the ID as an extra argument.
4923 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4924 both IPv4 and IPv6 based ID's.
4926 The affected files are lib/silccore/id.[ch] and other files
4927 around the tree using these routines.
4929 * Removed the ID length arguments in server from various
4930 silc_server_send_notify_* routines -> they are not needed
4933 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4935 * Fixed memory leak in silc_encode_pem_file in the file
4936 lib/silcutil/silcutil.c.
4938 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4940 * Check minor version as well in the SKE. Affected files are
4941 silcd/protocol.c and lib/silcclient/protocol.c.
4943 * Added --identifier option to the server so that an identifier
4944 can be when creating the public key for the server. Affected
4945 file is silcd/silcd.c.
4947 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4948 lib/silccrypt/silcpkcs.c.
4950 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4952 * Register default ciphers and stuff when using -C option with
4953 the server. Affected file sildc/silcd.c.
4955 * Put back the servers public key filename format, it is better
4956 than the new one. For now, the client keys are saved with the
4957 new filename format. The affected file silc/client_ops.c.
4959 * Implemented the Cipher API for the rest of the ciphers that
4960 did not implement it or implemented it the wrong way.
4962 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4964 * Register default ciphers and stuff when using the -S option
4965 in the client. Affected file silc/silc.c. Same also when
4966 creating new key pair with -C option.
4968 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4970 * Fixed the silc_verify_public_key client operation function to
4971 save the public keys differently. The fingerprint is now
4972 used as filename and not the hostname. This way also the
4973 client keys are saved uniquely and not with hostnames. The
4974 affected file is silc/client_ops.c.
4976 * Trimmed the silc_hash_fingerprint function to remove extra
4977 whitespaces from the end of the fingerprint. The affected
4978 file is lib/silccrypt/silchash.c.
4982 * Added silc_cipher_register_default function to register all
4983 default ciphers. It can be used when configuration files
4984 does not exist and the application does not want any specific
4985 ciphers in any specific order.
4987 The SilcDList is now used as silc_cipher_list dynamically
4988 allocated cipher list. Removed the static list all together
4989 and now all ciphers must be allocated to the dynamic list.
4990 The silc_cipher_alloc routine was changed to check only the
4993 All silc_cipher_* routines that used to return int returns
4996 The affected files lib/silccrypt/silccrypt.[ch].
4998 * The same thing was done to silc_hash_* as for silc_cipher_*
4999 routines. Affected files lib/silccrypt/silchash.[ch].
5001 * The same thing was done to silc_pkcs_* as for silc_cipher_*
5002 routines. Affected files lib/silccrypt/silcpkcs.[ch].
5003 Added also silc_pkcs_[un]register[_default] functions.
5004 Removed the data_context from the PKCS API.
5006 * Added silc_hmac_register_default function to register default
5007 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
5008 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
5009 to unregister all hmacs at once.
5011 * Register the default ciphers, hash functions, PKCSs and HMACs
5012 if client's configuration file does not exist. The affected
5015 * The client did not load the hash functions from the SIM
5016 modules at all. Added support for this. Affected file is
5017 silc/clientconfig.c.
5019 * When decoding public key with silc_pkcs_public_key_decode, check
5020 the supported algorithm only if PKCS are registered. Affected
5021 file lib/silccrypt/silcpkcs.c. The same was done with the
5022 silc_pkcs_private_key_decode.
5024 * Fixed the SILC List routines to keep the list always in order.
5025 It used to change the list's order when traversing the list but
5026 not it preserves the order. Affected file lib/trq/silclist.h.
5028 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5030 * Added the client library to use the SilcSocketConnection's
5031 reference counter (by silc_socket_dup) to prevent the bug that
5032 the socket object may be freed underneath async operation.
5034 * The name resolv library checking fixes in the configure.in.pre.
5037 * Created new version of the protocol drafts for future
5038 development. The -03 drafts are the ones that will be changed
5039 in the trunk now and the -02 will remain as they are.
5041 * Send list of CUMODE notifys to the router when announcing
5042 the channel users to the router. Affected file silcd/server.c.
5043 If the router receiving channel founder CUMODE for a channel
5044 that already has channel founder it will send CUMODE notify
5045 to the sender to remove the channel founder rights from the
5046 announced client. Affected file silcd/packet_receive.c.
5048 * The CUMODE notify may now use Server ID as well as the entity
5049 who changes the mode. Updated protocool specs.
5051 * Updated INSTALL and README files.
5053 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5055 * New web pages in the http://silc.pspt.fi. The pages was
5060 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5062 * Implemented the [DenyConnectin] config section in the server.
5063 Added silc_server_config_denied_conn to check whether incoming
5064 connection is denied. Affected file silcd/serverconfig.[ch].
5066 * Do not check the ports when checking the incoming configuration
5067 data if the port is 0, meaning any. Affected file is
5068 silcd/serverconfig.c.
5070 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5072 * Fixed buffer overflow in silc_string_compare in the file
5073 lib/silcutil/silcutil.c.
5075 * Fixed double free in silc_server_command_leave in the file
5078 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5080 * Fixed the version checking in the server. Affected file is
5083 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5085 * Fixed the configuration data fetching when accepting new
5086 connections in the server. Affected file silcd/server.c.
5088 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5090 * Added `sender_entry' argument to the function
5091 silc_server_packet_relay_to_channel so that we can check
5092 whether some destination actually belongs to the same route
5093 the sender belongs (ie, we must not resend the packet to the
5094 sender). Affected file silcd/packet_send.[ch].
5096 * Added `servername' field to the SilcClientEntry in the server
5097 to hold the name of the server where client is from. Affected
5098 file is silcd/idlist.h.
5100 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5102 * Moved the channel message encrypting in the router betwen
5103 router connections from silc_server_channel_message to the
5104 silc_server_packet_relay_to_channel since we want to check
5105 whether we have anybody channel before encrypting anything.
5106 Affected files silcd/packet_[receive/send].c.
5108 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5110 * Fixed the [AdminConnection] server config section to support
5111 multiple entries. Affected file silcd/serverconfig.c.
5113 * Added support into the server to check the validity of the
5114 incoming connection before executing any KE or authentication
5117 * The connection configuration is now saved to the KE and
5118 connection auth protocol contexts and not fetched anymore in
5119 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
5121 * The local hosts listenning address and port is also resolved
5122 now when starting the server. We want to have the socket object
5123 to include the real address and port for the listener. Added
5124 new function silc_net_check_local_by_sock into the files
5125 lib/silcutil/silcnet.[ch].
5127 * Fixed a broadcast bug in server -> do not broadcast if we
5130 * Fixed a routing bug. Do not route broadcast packets ever.
5131 Broadcast packets must be processed always and not routed since
5132 they may be destined to some other host than yourself and thus
5133 would get routed without no good reason. Affected file is
5136 * Added function silc_server_config_is_primary_route to check
5137 whether primary router connection has been configured (a router
5138 configuration that we are initiating). If there is not, we
5139 will assume that there is only two routers in the SILC network
5140 and we will use the incoming router connection as our primary
5141 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
5143 * Changed the order of the broadcasting. Broadcast _after_ the
5144 packet has been processed not before. Affected file is
5147 * Fixed a [ClientConnection] parsing bug. The port was never
5148 parsed correctly thus resulting to port 0. Affected file
5149 silcd/serverconfig.c.
5151 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
5152 argument and did not set the broadcast packet flag. Affected
5153 file silcd/packet_send.c. Fixed same bug in the function
5154 silc_server_send_notify as well.
5156 * If we receive NEW_ID packet for our own ID in the server, ignore
5159 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5163 * Removed the nickname from the Private Message Payload.
5164 Updated the code and the protocol specs.
5166 * Updated protocol specs for submitting to the IETF.
5168 * Tweaked the Random Number Generator a bit. Affected file
5169 lib/silccrypt/silcrng.c. Exported a new function
5170 silc_rng_[global]_add_noise which can be used to add more
5173 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5175 * Do not parse packets with different timeout when protocol
5176 is active -> may cause problem with rekey. Affected file
5179 * When server receives signoff notify it must not create
5180 new channel key if the client is on any channels since the
5181 sender of the signoff notify will create it.
5183 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5185 * Added printing of error messages during SKE protocol from the
5186 failure packet sent by server during SKE. Affected file
5189 * Removed the client's failure_callback handling with timeout
5190 and handle it immediately when received.
5192 * The SKE library returned wrong type in SUCCESS and FAILURE
5193 packets. They must be 32 bit MSB not 16 bit MSB.
5195 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5197 * Ok, rewrote the logic of the re-key and now it seems to work.
5198 I tested it on high traffic with frequent re-keys without
5199 problems. Added hmac_receive (and renamed hmac to hmac_send)
5200 in SilcClientConnection in lib/silcclient/client.h and
5201 in SilcIDListData in silcd/idlist.h. Also, removed the
5202 SilcPacketParserContext's cipher and hmac fields as they are
5203 not needed anymore and actually caused some problems when
5204 the ciphers and hmac's changed underneath the packet parser.
5206 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5208 * If re-key protocol is active then process the incoming packets
5209 synchronously since we must assure that icoming packets encrypted
5210 with the old key is processed before the new keys is set to
5211 use. This is true other packets than for REKEY packets.
5212 Affected file silcd/server.c. The same was done to client library
5213 as well, affected file lib/silcclient/client.c.
5215 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5217 * Fixed bug in client and server to accept the force send if
5218 the packet is send from silc_[server/client]_packet_process
5219 function. Otherwise the packets are never delivered, oops.
5221 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5223 * Disable force sending of packets when REKEY protocol is active.
5224 We must assure that no packet is sent directly when rekey is
5225 performed. All packets must be sent through packet queue.
5226 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
5227 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
5228 function is silc_[server/client]_packet_send_real to check
5231 * Replaced the SIM paths from example config files to
5232 /usr/local/modules. Also, make install creates now
5233 /usr/local/silc/logs directory to hold all the SILC server
5236 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5238 * Made the configure.in.pre work on Solaris. Patch by salo.

5247 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5249 * When MAC computation fails the silc_packet_decrypt returned 0
5250 even though it was supposed to return -1. Fixed this. The
5251 affected file is lib/silccore/silcpacket.c.
5253 * Do not replace the config files in /etc/silc (in make install)
5254 if they already exist. Affected file ./Makefile.am.
5256 * Do not send re-key packets immediately but through packet queue.
5257 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
5259 * Changed silc_net_check_host_by_sock to return FALSE if the
5260 IP/DNS could not be resolved. Though, it returns the IP address
5261 now even if it could not resolve it (but returns also FALSE).
5262 Affected file lib/silcutil/silcnet.[ch].
5264 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5266 * Added silc_pkcs_decode_identifier to decode the public key's
5267 identifier. Affected file lib/silccrypt/silpkcs.[ch].
5268 Added also silc_pkcs_free_identifier. Added also new context
5269 SilcPublicKeyIdentifier.
5271 * Added -S option to the silc client. It is used to dump the
5272 contents of the specified public key file.
5274 * Changed the PKCS api to return the public key length when
5275 setting the public key.
5277 * Fixed a fatal bug in the public and private key file loading.
5278 Affected file lib/silccrypt/silcpkcs.c.
5280 * Execute the packet parsing for client with zero (0) timeout
5281 if the protocol is active. Affected file silcd/server.c.
5283 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5285 * Made the key generation options to the silcd program. Added
5286 -C option, equivalent to client's option.
5288 * Added new [ServerKeys] config section to the server. It
5289 configures the server's public and private key.
5291 * Defined generic Public Key Payload into the protocol
5292 specification to send specific type of public keys and
5295 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
5296 public key or certificate.
5298 * Implemented the GETKEY command to the server and to the
5299 client library and on user interface.
5301 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5303 * Made preliminary `make install' work.
5305 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5307 * Added SilcServerRekey context into silcd/idlist.h.
5309 * Added the PFS support as defined in the specification to the
5310 SKE protocol. Affected files lib/silcske/*.c.
5312 * Added `ske_group' field to the SilcServerRekey context to hold
5313 the number of the SKE group that is used with PFS in re-key.
5314 Affected file silcd/idlist.h.
5316 * Added PFS re-key support to the server. Affected file is
5319 * Added silc_protocol_cancel to cancel execution of the next
5320 state of the protocol. Affected file is
5321 lib/silccore/silcprotocol.[ch].
5323 * Added the re-key support with and without PFS to the client
5324 library. Re-key is performed once in an hour, by default.
5326 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
5327 Added silc_client_rekey_callback and silc_client_rekey_final.
5328 Affected files are lib/silcclient/protocol.[ch] and
5329 lib/silcclient/client.[ch].
5331 * Removed the `hmac_key' and `hmac_key_len' fields from the
5332 SilcClientConnection structure; not needed. Affected file is
5333 lib/silcclient/client.h.
5337 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5339 * Do not ask whether user wants to use the negotiated private key
5340 for private messages, just use it. Affected file is
5341 silc/local_command.c.
5343 * Added `send_enc_key' and `enc_key_len' fields to the
5344 SilcIDListData structure since they are needed in the re-key
5345 phase. Affected file is silcd/idlist.[ch].
5347 * Implemented the simple re-key protocol into the server.
5348 Affected files silcd/server.c and silcd/protocol.[ch]. The
5349 re-key will be performed once in an hour, by default.
5351 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
5352 Added silc_server_rekey, silc_server_rekey_callback and
5353 silc_server_rekey_final.
5355 * Removed Tunneled flag from the protocol. Updated the code
5356 and the specifications.
5358 * Adde `pfs' field to the SilcIDListData to indicate whether
5359 the PFS is to be performed in the re-key. Affected file is
5362 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5364 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
5365 int64 of at least the xintXX size. If void * is less that 4
5366 bytes uint32 * will be used. Defined bool as boolean.
5368 * Changed _ALL_ unsigned long and unsigned int to uint32,
5369 unsgined short to uint16 in the source tree.
5371 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
5372 not handle clients that has entry->data.registered == FALSE.
5373 They are not in the network anymore. Affected file is
5376 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5378 * Implemented the sending of the SERVER_SIGNOFF notify in the
5379 server. Affected file is silcd/server.c.
5381 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
5382 Added also silc_notify_payload_encode_args into the
5383 lib/silccore/silcnotify.[ch].
5385 * Implemented ther SERVER_SIGNOFF notify handling in the server.
5386 Affected file silcd/packet_receive.c.
5388 * Implemented the SERVER_SIGNOFF notify handling in the client
5389 library. Affected file lib/silcclient/client_notify.c. Also,
5390 implemnted the printing of the SERVER_SIGNOFF info to the
5391 application. Affected file silc/client_ops.c.
5393 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
5394 if the deleting was successful. Affected file silcd/idlist.[ch].
5396 * Added support for public key authentication in the connection
5397 authentication protocol in the client library. Affected file
5398 lib/silcclient/protocol.c.
5400 * Changed the server's silc_idlist_get_clients_by_* interface
5401 to support already allocated array so that new entries may be
5402 added to pre-allocated array. Affected file silcd/idlist.[ch].
5403 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
5404 and command replies.
5406 * All command reply functions in the server now calls the
5407 pending command callback even if error occured. This way the
5408 error will be delivered to the client as well. Affected files
5409 silcd/command.c and silcd/command_reply.c.
5411 * Fixed INFO command to return local server's info if no server
5412 was provided. Affected file lib/silcclient/command.c.
5414 * Removed RESTART command for good. Updated the code and the
5417 * Rewrote parts of the task system. It is a bit simpler now.
5418 Removed unsued task priorities. The affected files are
5419 lib/silcutil/silctask.[ch].
5421 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5423 * Moved the USERS printing from the library to the application.
5424 Affected files lib/silcclient/command.c and silc/client_ops.c.
5426 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5430 * Added channel key re-key support. The re-key is perfomed
5431 only by the router and is done once in an hour. Added `rekey'
5432 field to the SilcChannelEntry in the server. Affected files
5433 silcd/server.c and silcd/idlist.h.
5435 * Added silc_task_unregister_by_context into the file
5436 lib/silcutil/silctask.[ch].
5438 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5440 * Added SILC_UMODE_GONE mode to indicate when the client is not
5441 present in the SILC network. Added also support to the local
5442 command AWAY that will set this mode. Added support of showing
5443 "xxx is gone" in WHOIS command. The USERS command shows the
5444 gone status as well.
5446 * Fixed setting server and router operator privileges in the
5447 server's UMODE command. Affected file silcd/command.c.
5449 * Merged the SKE KE1 and KE2 payloads into one payload. The
5450 new KE payload is equivalent to the old KE2 payload.
5452 Cleaned up the SKE Start Payload parsing. It now uses the
5453 simple buffer unformatting to do the parsing. A lot faster
5456 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
5457 to the SKE that is used to indicate whether both of the SKE
5458 parties should perform authentication. By default only the
5459 responder performs authentication. By setting this flag also
5460 the initiator must do authentication. By default it is unset
5461 since in normal SKE case, client to server connection, only
5462 the responder should do authentication. When doing SKE between
5463 two clients both should perform authentication. Updated the
5464 code and the protocol specs.
5466 * A little fix to IDENTIFY command in the server. Search the
5467 client first by hash not nickname. Affected file is
5470 * Fixed the silc_client_close_connection to support closing
5471 the client to client connections wihtout deleting too much
5472 data. Affected file lib/silcclient/client.c.
5474 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
5475 are received if protocol used to be active but is not anymore
5476 the application would crash due to NULL pointer dereference.
5477 Affected files silcd/server.c and lib/silcclient/client.c.
5479 * Added `hash' field to the SilcClientConnection to include
5480 the hash function negotiated in the SKE protocol.
5482 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
5483 to set the channel founder authentication data. A client can
5484 claim the founder rights later by providing the authentication
5485 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
5486 This way the channel founder can regain the channel founder
5487 privileges even it is left the channel. This works only on
5488 local server and the client must be connected to the same
5489 server to be able to regain the founder rights. Updated the
5490 protocol specs accordingly.
5492 Added support to the CMODE command in the client to set the
5493 founder auth data. Read the README to see how to set it.
5495 Added support to the CUMODE command to claim the founder
5496 rights. Read the README to see how to do it.
5498 Added support for the founder authentication to the Channel
5499 Entry in the server. Affected file silcd/idlist.h.
5501 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
5502 server's CMODE command. Affected file silcd/command.c.
5504 * Added the following new functions into lib/silccore/silcauth.[ch]:
5505 silc_auth_get_method and silc_auth_get_data.
5507 * The server now saves the remote hosts public key to the
5508 SilcIDListData pointer. Affected file silcd/protocol.c.
5510 * The normal server now does not remove the channel entry from
5511 the cache if the founder authentication data is set. It used
5512 to remove it if the founder was the last one on the channel on
5513 the server and left the channel. The auth data is saved and
5514 if the channel is re-joined later the old entry is used with
5515 the old auth data. Affected files silcd/command_reply.c and
5518 * Removed the `pkcs' field from the SilcIDListData structure
5519 in the server; it is not used. Affected file silcd/idlist.h.
5521 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5523 * Fixed packet processing on slow links. Partial packets were
5524 never re-processed because the incoming data buffer was cleared
5525 by the application. Application must not directly clear the
5526 sock->inbuf, the packet processing routines handle it. Fixed
5527 this in client library and in server.
5529 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5531 * Fixed the WHOIS and IDENTIFY send reply function to really
5532 check whether to send list or just one entry. Affected file
5535 * Cleaned up the LEAVE command's channel key distribution. The
5536 affected file silcd/command.c.
5538 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
5539 can enforce the channel mode as well. In that case the ID
5540 includes the ID of the server. The code now enforces the
5541 mode change if the router have different mode than the server.
5543 * The notify client operation with CMODE_CHANGE notify can now
5544 return NULL client_entry pointer if the CMODE was not changed
5545 by client. Application must check for this.
5547 * Added <Server ID> argument to INFO command to support server
5548 info fetching by Server ID.
5550 * Added silc_server_announce_get_channel_users to get assembled
5551 packets of channel users of the specified channel. Affected
5552 file silcd/server.[ch].
5554 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
5555 was freed underneath the ID Cache.
5557 * Re-announce clients when the server received CHANNEL_CHANGE
5558 notify from the router. Affected file silcd/packet_send.c.
5560 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5562 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
5563 crashed since it did not handle the fact that there is no cipher
5564 called "3" and didn't check the error condition. Now fixed.
5566 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
5567 flag. It can be used to send message requests.
5569 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5571 * Implemented the RESTART command in the client.
5573 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
5574 notice type messages. Added notice printing to the user
5577 * The channel keys are not re-generated if the channel's mode
5578 is PRIVKEY, ie private key on the channel exists. Affected
5579 files silcd/server.c and silcd/command.c.
5581 * Fixed a little bug in channel message delivery when channel
5582 private keys are set in the server. Affected file is
5583 silcd/packet_send.c.
5585 * Changed the setting on channel->on_channel = TRUE from the
5586 silc_client_save_channel_key to the JOIN command reply. The
5587 key payload is not received if the private channel key is set.
5588 Affected file lib/silcclient/command_reply.c and the
5589 lib/silcclient/client_channel.c.
5591 * When the CMODE_CHANGE notify is sent and the channel private
5592 key mode is removed the channel key must be re-generated in
5593 other cells as well. Added this support for the router in the
5594 silcd/packet_receive.c.
5596 * Added new local command NOTICE to send notice message on
5597 channel. Affected file silc/local_command.[ch].
5599 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5601 * Added new local command ME to the client. It is used to send
5602 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
5603 some action. Affected file silc/local_command.[ch].
5605 * Changed channel_message and private_message client operations
5606 to deliver the message flags to the application. Added also
5607 the `flags' arguments to the silc_client_send_channel_message
5608 and silc_client_send_private_message functions. Affected file
5611 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5613 * Redefined the Private Message Payload to support private message
5614 keys and to support the new private message flags. Updated
5615 the protocol specs. Flags makes it possible to have for example
5616 CTCP style messages.
5618 * Added new type SilcPrivateMessagePayload and defined an API
5619 for it in the lib/silcclient/silcprivate.[ch].
5621 * Tested private message private keys successfully. Tested the
5622 private message key set, unset and list commands with the new
5625 * Redefined the Channel Message Payload to include the channel
5626 message flags (equal with private message flags) to support
5627 for example CTCP style messages.
5629 * Defined some of the message (for channel and private message)
5630 flags. Updated the protocol specs and added the flags to the
5631 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5633 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5635 * Added SilcKeyAgreementStatus type to the key agreement routines
5636 to indicate the current status and error if one occured.
5637 The status types are defined in the lib/silcclient/silcapi.h.
5639 * Added new local command KEY that is used to set and unset private
5640 keys for channels, set and unset private keys for private messages
5641 with remote clients and to send key agreement requests and
5642 negotiate the key agreement protocol with remote client. The
5643 key agreement is supported only to negotiate private message keys,
5644 it currently cannot be used to negotiate private keys for channels,
5645 as it is not convenient for that purpose.
5647 * Fixed a minor pending callback setting bug in the function
5648 silc_client_get_client_by_id_resolve, now the function works.
5649 Affected file lib/silcclient/idlist.c.
5651 * Added function silc_net_get_local_port to get local bound
5652 port by socket. Added to lib/silcutil/silcnet.[ch].
5654 * Added `sockets' and `sockets_count' fields to the SilcClient
5655 object. They hold the sockets of the listenning sockets in
5656 the client. Listenning sockets may be for example the key
5657 agreement server. Affected file lib/silcclient/client.[ch].
5658 Added functions the silc_client_add_socket and the
5659 silc_client_del_socket. They are exported to the application
5662 * Added ~./silc/clientkeys to support other client's public keys.
5664 * Renamed verify_server_key client operation to verify_public_key
5665 and added one argument to indicate the type of the connection
5666 (server, client etc.).
5668 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5670 * Added silc_server_connection_auth_request to handle the
5671 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5672 silcd/packet_receive.[ch].
5674 * Added silc_server_send_connection_auth_request into the
5675 silcd/packet_send.c to send the connection auth request packet.
5677 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5680 * Fixed the public key authentication in responder side in the
5681 server. The `auth_data' pointer includes the SilcPublicKey
5682 not the path to the public key. Affected file silcd/protocol.c.
5684 * Implemented the public key authentication in the initiator side
5685 in the server. Affected file silcd/protocol.c.
5687 * Removed the [RedirectClient] config section from the server
5688 configuration. Is not needed and I don't want to implement it.
5690 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5692 * Cleaned up the CMODE command in the server. It now works
5693 correctly and supports all the modes defined in the protocol.
5694 Affected file is silcd/command.c.
5696 * Added `hmac_name' field to the SilcChannelEntry in the server
5697 to hold the default HMAC of the channel. It can be set when
5698 creating the channel (with JOIN command). Affected files
5701 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5702 type to indicate the change of the current cipher and hmac
5703 on the channel. Client can safely ignore the <cipher> argument
5704 (if it chooses to do so) since the CHANNEL_KEY packet will
5705 force the channel key change anyway. The <hmac> argument is
5706 important since the client is responsible of setting the new
5707 HMAC and the hmac key into use.
5709 * Fixed the CMODE command in the client library as well.
5711 * Tested CMODE command in router environment successfully.
5713 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5715 * Show the version of the remote client (or server) when connecting
5716 to the server. It is logged to the log file. Affected file
5717 is silcd/protocol.c.
5719 * Fixed the KILLED notify handling in the client library. The
5720 client must be removed from all channels when receiving the
5723 Also, do not remove the client entry when giving the KILL
5724 command but when the KILLED notify is received.
5726 * Removed silc_idlist_find_client_by_nickname from the server.
5727 Not needed anymore. Affected files silcd/idlist.[ch].
5729 * Implemented the CHANNEL_CHANGE notify type handling to the
5730 server. Affected file silcd/server.c.
5734 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5736 * Added silc_server_send_notify_invite to send the INVITE
5737 notify between routers.
5739 * Implemented the INVITE command correctly to the server.
5741 * Implemented the INVITE notify type handling in the server.
5743 * Implemented the INVITE command to the client library and on the
5746 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5748 * Added function silc_server_get_client_resolve to find the
5749 client entry by ID from all ID lists and then resolve it
5750 (using WHOIS) if it cannot be found. Affected file is
5753 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5755 * Implemented the BAN command to the client library.
5757 * The JOIN command in the server now checks the invite list
5760 * Changed the silc_command_reply_payload_encode_va and the
5761 silc_command_payload_encode_va to support that if argument is
5762 NULL it ignores and checks the next argument. Affected file
5763 lib/silccore/silccommand.c.
5765 * Added silc_server_send_notify_ban to send the BAN notify
5766 type between routers.
5768 * Chaned the silc_notify_payload_encode to support that if
5769 argument is NULL it ignores and checks the next argument.
5770 Affected file lib/silccore/silcnotify.c.
5772 * Tested ban lists in router environment successfully.
5774 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5776 * Implemented BAN command to the server, in silcd/command.[ch].
5778 * Removed the BAN and INVITE_LIST modes from the CMODE command
5781 * Added function silc_string_match to regex match two strings.
5782 Affected files lib/silcutil/silcutil.[ch].
5784 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5786 * Redefined parts of the SilcChannelEntry in the server to support
5787 the new ban and invite lists.
5789 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5791 * Redefined the INVITE command. The same command can be used to
5792 invite individuals to the channel but also to manage the invite
5793 list of the channel (to add to and remove from the invite list).
5794 Updated the protocol specs.
5796 * Added new command SILC_COMMAND_BAN that can be used to manage
5797 the ban list of the channel. Updated the protocol specs.
5799 * Removed the channel modes: the SILC_CMODE_BAN and the
5800 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5801 in the CMODE command. The equivalent features are now available
5802 using INVITE and BAN commands. Updated the protocol specs.
5804 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5805 in the network about change in the current ban list. The notify
5806 type is not used by the client.
5808 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5809 support the invite lists.
5811 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5813 * Added new function silc_string_regexify that converts string
5814 including wildcard characters into regex string that can
5815 be used by the GNU regex library. Added into the file
5816 lib/silcutil/silcutil.[ch].
5818 Added silc_string_regex_combine to combine to regex strings
5819 into one so that they can be used as one regex string by
5820 the GNU regex library. Added into the file
5821 lib/silcutil/silcutil.[ch].
5823 Added silc_string_regex_match to match two strings. It returns
5824 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5826 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5828 * Imported GNU regex to the soruce tree into lib/contrib.
5829 Fixed some compiler warning from the regex.c.
5831 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5833 * Fixed MOTD command in the server to work in router environment.
5835 * Fixed the MOTD command in the client library to support
5836 the server argument in the command.
5838 * Added `nickname_len' argument to the silc_idlist_add_client
5839 in the server, as the `nickname' argument may be binary data
5842 * Added silc_idlist_get_channels to return all channels from
5845 * Implemented LIST command to the server. Affected file is
5848 * Implemented the LIST command to the client library and on the
5851 * Added [<user count>] argument to the LIST command reply.
5852 With private channels the user count is not shown.
5854 * Updated TODO and README.
5856 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5858 * The client entry's data.registered must be TRUE even with
5859 global client entry on global client list. The data.registered
5860 is used to check whether the client is anymore in the network,
5861 for example with WHOWAS command so it must be valid.
5863 * Fixed the WHOWAS command in the server. It now actually works
5864 in router environment. Added function into silcd/command_reply.c
5865 silc_server_command_reply_whowas_save.
5867 * Added silc_idlist_purge function to the silcd/idlist.c
5868 to periodically purge the ID Cache.
5870 * Fixed INFO command in the server. It works now in router
5871 environment. Added <server name> argument to the INFO command
5872 reply. Updated the protocol specs.
5874 * Fixed minor bug in silc_idcache_purge to not purge if the
5875 expire value is zero.
5877 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5878 they were buggy because of the WHOWAS information.
5880 * Fixed local command MSG to handle the async resolving of
5881 the remote client properly. It used to fail the first MSG.
5882 Affected file silc/local_command.c.
5884 * Added `data_len' field to SilcIDCache context.
5886 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5888 * Update TODO. Todo in commands in the server.
5890 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5892 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5893 used by routers as broadcast packet to inform other routers
5894 about the changed user mode.
5896 Implemented the notify handling in the server. Affected file is
5897 silcd/packet_receive.c. Added the function
5898 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5900 * Added new generic Channel Payload and deprecated the New Channel
5901 Payload. The New Channel Payload is now the generic Channel
5904 * Added new argument `mode' to the silc_server_send_new_channel
5905 as it is required in the Channel Payload now.
5907 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5908 and created a new and real SilChannelPayload to represent the
5909 new generic Channel Payload. Implemented the encode/decode
5910 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5912 * Added silc_server_get_client_channel_list to return the list
5913 of channels the client has joined for WHOIS command reply.
5914 Affected file silcd/server.[ch].
5916 * Implemented the channel list sending in the WHOIS command reply
5917 in server and in the client.
5919 Implemented the channel list displaying on the user interface
5920 as well. Affected file silc/client_ops.c.
5922 * Added silc_channel_payload_parse_list to parse list of Channel
5923 Payloads. It returns SilcDList list of SilcChannelPayloads.
5924 Client for example can use this function to parse the list of
5925 channels it receives in the WHOIS command reply. The caller
5926 must free the list by calling silc_channel_payload_list_free.
5927 Affected files lib/silccore/silcchannel.[ch].
5929 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5931 * Added one new argument <user mode> to the WHOIS command reply
5932 to return the mode of the user in SILC. Updated the protocol
5935 Implemented it to the server and client.
5937 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5939 * Fixed the mode printing on the user interface on joining.
5940 Affected file silc/client_ops.c.
5942 * Implemented the UMODE command and user modes in general to the
5943 client library and to the user interface.
5945 * Implemented the UMODE command to the server.
5947 * The server now sends UNKNOWN_COMMAND error status if client sends
5948 unknown command. Affected file silcd/command.c.
5950 * All server commands now handle the command identifier the right
5951 way when sending the command reply to the client. The client can
5952 use to identify the command replies with the identifier.
5954 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5956 * Added silc_server_get_client_route to resolve the route to
5957 the client indicated by the client ID. Affected file is
5960 * Added silc_server_relay_packet as general function to relay
5961 packet to arbitrary destination. This deprecates functions
5962 like _send_private_message_key, _relay_notify etc. Affected
5963 file is silcd/packet_send.[ch].
5965 Removed silc_server_send_key_agreement,
5966 silc_server_send_private_message_key and
5967 silc_server_packet_relay_notify functions from the file
5968 silcd/packet_send.[ch].
5972 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5973 server. Affected file silcd/packet_receive.[ch].
5975 * Implemented the KILL command to the client. Implemented the
5976 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5977 Affected files lib/silcclient/command[_reply].c and
5978 lib/silcclient/client_notify.c. Implemented the KILL notify
5979 printing in the user inteface.
5981 * Fixed a lot silc_parse_nick memory leaks from the client
5982 library in the file lib/silcclient/command.c.
5984 * Changed the silc_server_send_notify_on_channels's `sender'
5985 argument from SilcSocketConnection to SilcClientEntry to
5986 check the sender as entry and not as connection object and not
5987 to send to the client provided as argument. The affected file
5988 is silcd/packet_send.[ch].
5990 * The notify packets that are destined directly to the client used
5991 to not to be processed by the server. Now changed that and the
5992 server processes all notify packets. After relaying the packet
5993 to the client the notify packet is processed in the server.
5995 * The silc_server_free_client_data now checks whether there is
5996 pending outgoing traffic for the client and purges the data to
5997 the network before removing the client entry.
5999 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6001 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
6002 an client is killed from the SILC Network. Updated the protocol
6005 Added new function silc_server_send_notify_killed to the
6006 silcd/packet_send.[ch].
6008 * Added function silc_server_packet_relay_notify to relay notify
6009 packets that are destined directly to a client. In this case
6010 the server does not process the notify packets but merely relays
6011 it to the client. Affected file silcd/packet_send.[ch].
6013 Added also silc_server_packet_process_relay_notify to check
6014 whereto relay the notify. Affected file is
6015 silcd/packet_receive.[ch].
6017 * Implemented the KILL command to the server.
6021 * Added the backup schema desgined last fall to the protocol
6022 specs for everyone to see. The specification is in the
6023 *-spec-xx.txt draft and the packet type definitions for the
6024 backup routers is in *-pp-xx.txt draft. Thusly, added also
6025 new packet type SILC_PACKET_CELL_ROUTERS.
6027 * A big security problem in the implementation discovered. The
6028 signoff of an client did not cause new channel key generation
6029 which it of course should've done. The channel keys must be
6030 always re-generated when client leaves (or signoffs) the channel.
6031 The silc_server_remove_from_channels funtion now handles
6032 the channel key re-generation.
6034 * Added `sender' argument to the silc_server_send_notify_on_channels
6035 to not to send the client provided as argument. Affected file
6036 silcd/packet_send.[ch].
6038 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6040 * Implemented OPER and SILCOPER commands into the server and
6043 * Added silc_auth_verify and silc_auth_verify_data to verify
6044 the authentication directly from the authentication payload.
6045 It supports verifying both passphrase and public key based
6046 authentication. Affected file lib/silccore/silcauth.[ch].
6048 * Added `hash' field to the SilcIDListData structure. It is the
6049 hash negotiated in the SKE protocol. Affected file is
6052 * Slight redesigning of the SilcAuthPayload handling routines.
6053 Do not send SilcPKCS but SilcPublicKey as argument.
6055 * Implemented the public key authentication support to the
6056 serverconfig. The public key is loaded from the provided path
6057 and saved as authentication data to void * pointer. Thus,
6058 changed the unsigned char *auth_data to void *auth_data;
6060 * Fixed SHUTDOWN command to send the reply before the server
6061 is shutdown. :) Affected file silcd/command.c.
6063 * Fixed fatal bug in CONNECT command. The hostname was invalid
6064 memory and server crashed. Affected file silcd/command.c.
6066 * Fixed fatal bug in CLOSE command. The server_entry became
6067 invalid but was referenced later in the command. Affected file
6070 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6072 * Fixed fatal bug in failure packet handling. Server ignored
6073 the failure and thus crashed when it came.
6077 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6079 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
6080 that the command may be executed only once in (about) 2 seconds.
6081 The old SILC_CF_LAG flag is same but allows command bursts up
6082 to five before limiting.
6084 Added the support for CF_LAG and CF_LAG_STRICT flags to the
6085 server code. Various commands now includes the CF_LAG_STRICT
6086 flag to disallow any kind of miss-use of the command.
6088 * Fixed the silc_buffer_unformat to not to allocate any data
6089 if the length of the data is zero. It used to allocate the
6090 length + 1. Affected file lib/silcutil/silcbuffmt.c.
6092 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6094 * Changed the format of AdminConnection configuration section
6095 in the server. Added username of the admin to the format.
6096 Affected files silcd/serverconfig.[ch].
6098 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
6099 to return admin configuration data by host, username and/or
6102 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6104 * Implemented WHOWAS command to the server. Added the functions:
6106 silc_server_command_whowas_parse,
6107 silc_server_command_whowas_send_reply,
6108 silc_server_command_whowas_from_client and
6109 silc_server_command_whowas_from_server
6111 * Added <Client ID> argument to the WHOWAS command reply. Updated
6112 the protocol specs accordingly.
6114 * Implemented WHOWAS command and command_reply to the client
6117 Implemented the WHOWAS printing on the user interface.
6119 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6121 * Added new argument to the WHOWAS command reply, the real name.
6122 It is an optional argument. Updated the protocol specs.
6124 * Added SilcIDCacheDestructor callback that is registered when
6125 the SilcIDCache is allocated. The callback is called when
6126 an cache entry in the ID Cache expires, or is purged from the
6127 cache. Added into lib/silccore/idcache.[ch].
6129 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
6130 to destruct the client entries when the cache entry expires.
6131 Other ID Cache's in server and in the client library ignores
6134 * If the ID Cache entry's `expire' field is zero then the entry
6135 never expires. Added boolean `expire' argument to the
6136 silc_idcache_add function in the lib/silccore/idcache.[ch].
6137 If it is TRUE the default expiry value is used.
6139 * Added silc_server_free_client_data_timeout that is registered
6140 when client disconnects. By default for 5 minutes we preserve
6141 the client entry for history - for WHOWAS command.
6143 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6145 * Added support to the server to enforce that commands are not
6146 executed more than once in 2 seconds. If server receives
6147 commands from client more frequently, timeout is registered
6148 to process the commands. Affected file silcd/command.c.
6149 Added new function silc_server_command_process_timeout.
6151 * Changed NICK_NOTIFY handling in client library to check that
6152 if the client's nickname was changed, so there is no need to
6153 resolve anything from the server.
6155 * Removed error printing from the WHOIS and IDENTIFY commands.
6156 If error occurs then it is ignored silently in the client library.
6157 The application, however, may map the received error to
6158 human readable error string. The application currently maps
6159 the NO_SUCH_NICKNAME error to string.
6161 * Made the command status message public to the application. Moved
6162 them from lib/silcclient/command_reply.c to
6163 lib/silcclient/command_reply.h. The application can map the
6164 received command status to the string with the
6165 silc_client_command_status_message function.
6167 * Added check to the server to check that client's ID is same
6168 as the Source ID in the packet the client sent. They must
6171 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6173 * Added dist-bzip hook to the Makefile.am to make bzip2
6174 compressed distributions.
6176 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6178 * Server now enforces the maximum length for the nickname and
6179 the channel as protocol specification dictates. 128 bytes for
6180 nickname and 256 bytes for channel name.
6182 * Moved the WHOIS printing to the application. The client libary
6183 does not print out the WHOIS information anymore, the application
6184 must do it. Renamed silc_client_command_reply_whois_print to
6185 the silc_client_command_reply_whois_save.
6187 The client's idle time is also sent to the application now, and
6188 the idle is shown on screen.
6190 * Added silc_client_command_reply_identify_save to save the
6191 received IDENTIFY entries.
6193 * Do not check for channel private keys in message sending and
6194 reception if the channel does not have the PRIVKEY mode set.
6195 Affected file lib/silclient/client_channel.c.
6197 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6199 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
6200 just surfaced after chaning the JOIN procedure.
6202 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6204 * Added silc_client_get_clients_by_list to get client entries
6205 from Client ID list, that is returned for example by JOIN
6206 and USERS command replies. The application should use this
6207 function for example when JOIN command reply is received to
6208 resolve the clients already on the channel (library does not
6209 do that anymore as USERS command reply is not used in the JOIN
6210 procedure anymore). Affected files lib/silcclient/silcapi.h and
6211 lib/silcclient/idlist.c.
6213 * JOIN command reply and USERS command reply returns now SilcBuffer
6214 pointers instead of unsigned char pointers when returning
6215 the client list and mode list.
6217 * Added <Client ID> argument to the JOIN command reply, mainly
6218 for the server to identify for which client the command was
6219 originally sent. Updated protocol specs accordingly.
6221 * Added SilcDlist private_key pointer to the SilcChannelEntry
6222 in the client to support the channel private keys. Affected
6223 file is lib/silcclient/idlist.h.
6225 * Added SilcChannelPrivateKey argument to the function
6226 silc_client_send_channel_message so that application can choose
6227 to use specific private ke if it wants to. If it is not provided,
6228 the normal channel key is used, unless private keys are set.
6229 In this case the first (key that was added first) is used
6230 as the encryption key.
6232 * Implemented the support for channel private key handling.
6233 Implemented the following functions:
6235 silc_client_add_channel_private_key,
6236 silc_client_del_channel_private_keys,
6237 silc_client_del_channel_private_key,
6238 silc_client_list_channel_private_keys and
6239 silc_client_free_channel_private_keys
6241 Affected file lib/silcclient/client_channel.c.
6243 * Added the support for the private keys in the channel message
6244 sending and encryption and in the message reception and
6245 decryption. Affected funtions are
6246 silc_client_send_channel_message and silc_client_channel_message.
6248 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6250 * Added SKE's key verify callback to the client library's
6251 KE protocol context. Affected files lib/silcclient/protocol.[ch].
6253 * Removed the statement that server (or router) must send USERS
6254 command reply when joining to the channel so that the client
6255 knows who are on the channel. Instead, the client list and
6256 client's mode list is now sent in the JOIN command reply to the
6257 client who joined channel. This is better solution.
6259 * Added function silc_server_get_users_on_channel and function
6260 silc_server_save_users_on_channel to the silcd/server.[ch].
6262 * Removed function silc_server_command_send_users from the
6265 * Do not show topic on the client library anymore. The topic is
6266 sent in the command reply notify to the application and the
6267 application must show the topic now.
6269 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6271 * Added client searching by nickname hash into the IDENTIFY and
6272 WHOIS commands in the server as they were clearly missing from
6273 them. Affected file is silcd/command.c.
6275 * Fixed a bug in private message receiving in the client library.
6276 The remote ID was freed and it wasn't supposed, now it is
6279 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6281 * Minor fix to the channel payload; allocate the data area, as it
6282 needs to be of specific length.
6284 * If the key agreement port is zero then the operating
6285 system will define the bound port. Affected files are
6286 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
6288 * Added new function silc_channel_payload_decrypt into the file
6289 lib/silccore/silcchannel.[ch].
6291 * Moved the channel message etc, check from silc_packet_decrypt
6292 to applications. The library calls now a generic
6293 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
6294 when the packet is either normal or special. This was done to
6295 allow more wide range of checking that was not allowed when
6296 the code was in library. Now applications can do virtually any
6297 checks to the packet and return to the library the decision how
6298 the packet should be processed. Affected files are
6299 lib/silccore/silcpacket.[ch].
6301 Added silc_server_packet_decrypt_check to the server and
6302 silc_client_packet_decrypt_check to the client library.
6304 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
6305 to send with specified source and destination information.
6307 * Channel message delivery between routers was broken after the
6308 channel key distribution was fixed earlier. The channel key
6309 was used be to distributed to other routers as well which is not
6310 allowed by the protocol. Now this is fixed and channel keys
6311 really are cell specific and the channel message delivery between
6312 routers comply with the protocol specification.
6314 * Fixed various commands in server to check also the global list
6315 for the channel entry and not just the local list. The affected
6316 file silcd/command.c.
6318 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6320 * Added assert()s to buffer formatting and unformatting routines
6321 to assert (if --enable-debug) when error occurs. Affected
6322 file: lib/silcutil/silcbuffmt.c.
6324 * Changed to auto-reconnect to check whether the remote host is
6325 router and register the re-connect timeout if it is. It used
6326 to check that whether we are normal server, but router must do
6327 auto-reconnect with another router as well. Affected file
6330 * Removed the [<key len>] option from CMODE command as the cipher
6331 name decides the key length, nowadays. See the defined ciphers
6332 from the protocol specification.
6334 * Added [<hmac>] option to the CMODE command to define the HMAC
6335 for the channel. Added SILC_CMODE_HMAC channel mode.
6337 * Added [<hmac>] option for the JOIN command so that user can
6338 select which HMAC is used to compute the MACs of the channel
6341 * Added Hmac field to the Channel Message Payload. The integrity
6342 of plaintext channel messages are now protected by computing
6343 MAC of the message and attaching the MAC to the payload. The
6344 MAC is encrypted. Now, it is clear that this causes some
6345 overhead to the size of the packet but rationale for this is that
6346 now the receiver can verify whether the channel message decrypted
6347 correctly and also when private keys are set for the channel the
6348 receiver can decrypt the packet with several keys and check from
6349 the MAC which key decrypted the message correctly.
6351 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
6352 lib/silccrypt/silccipher.[ch].
6354 * Added silc_hash_len to return the digest length into the
6355 lib/silcrypt/silchash.[ch].
6357 * Rewrote parts of Silc Channel Payload interface in the
6358 lib/silccore/silcchannel.[ch]. The encode function now also
6359 encrypts the packet and parse function decrypts it.
6361 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6363 * Fixed a minor formatting bug in the SKE's key material processing.
6364 It actually might have processed the keys wrong way resulting
6367 * Redefined the mandatory HMAC algorithms and added new algorithms.
6368 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
6369 and hmac-md5 truncated to 96 bits. The mandatory is now
6370 hmac-sha1-96. Rest are optional (including the one that used
6371 to be mandatory). Rationale for this is that the truncated HMAC
6372 length is sufficient from security point of view and can actually
6373 make the attack against the HMAC harder. Also, the truncated
6374 HMAC causes less overhead to the packets. See the RFC2104 for
6377 * Added new [hmac] configuration section. The SKE used to use
6378 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
6379 is of course wrong. The official names that must be proposed in
6380 the SKE are the ones defined in the protocol specification
6381 (hmac-sha1-96 for example). The user can configure any hmac
6382 using any hash function configured in the [hash] section. At
6383 least, the mandatory must be configured.
6385 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
6387 * Added HMAC list to the SKE proposal list. It has now both
6388 hash algorithm list and HMAC list. This makes the protocol
6389 incompatible with previous versions. The SKE now seems to work
6390 the way it is supposed to work, for the first time actually.
6392 * Defined plain Hash algorithms to the protocol specification.
6395 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6397 * Implemented support for key agreement packets into the server.
6398 Added functions silc_server_key_agreement and
6399 silc_server_send_key_agreement. Other than these functions,
6400 server has nothing to do with this packet.
6402 * Added support for private message key packets into the server.
6403 Added functions silc_server_private_message_key and
6404 silc_server_send_private_message_key.
6408 * Changed the silc_[client|server]_protocol_ke_set_keys to be
6409 called in the protocol's final callback instead in the END
6410 protocol state. This makes a little more sense and in the same
6411 time in client we can use the same protocol routines for normal
6412 key exchange and to key agreement packet handling as well.
6414 * Added to both client's and server's KE protocol context the
6415 SilcSKEKeyMaterial pointer to save the key material. We will
6416 bring the key material to the protocol's final callback by doing
6417 this. The final callback must free the key material.
6419 * Added SKE's packet_send callback into client's KE protocol
6420 context so that the caller can choose what packet sending function
6421 is used. This way we can use different packet sending when
6422 doing normal SKE when doing key agreement packet handling (in
6423 the key agreement packet handling we do not want to encrypt
6426 * Implemented the responder side of the key agreement routines
6427 in the client. The client can now bind to specified port and
6428 accept incoming key negotiation. The key material is passed
6429 to the application after the protocol is over.
6431 * Implemented the processing of incoming Key Agreement packet
6432 in the client. Added function silc_client_key_agreement to
6435 * Implemented the intiator side of the key agreement routines
6436 in the client. The client can now initiate key agreement with
6437 another remote client. The key material is passed to the
6438 application after the protocol is over.
6440 * Created client_keyagr.c to include all the key agreement
6443 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
6444 SILC_TASK_CALLBACK except that it is not static.
6446 * Created client_notify.c and moved the Notify packet handling
6447 from the client.[ch] into that file.
6449 * Created client_prvmsg.c and moved all private message and
6450 private message key routines from the client.[ch] into that file.
6452 * Create client_channel.c and moved all channel message and
6453 channel private key routines from the client.[ch] into that file.
6455 * Changed silc_client_get_client_by_id_resolve to resolve with
6456 WHOIS command instead of IDENTIFY command, in the file
6457 lib/silclient/idlist.c.
6459 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6461 * Implemented the SKE's responder side to the Client library.
6463 * When FAILURE is received to the protocol do not trust it
6464 blindly. Register a timeout to wait whether the remote closes
6465 the connection as it should do it, only after that process the
6466 actual failure. This was changed to both client and server.
6468 * Added client_internal.h to include some of the structures
6469 there instead of client.h in lib/silcclient/.
6471 * Added function silc_task_unregister_by_callback to unregister
6472 timeouts by the callback function.
6474 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6476 * Some "Incomplete WHOIS info" errors has been appearing on the
6477 log files. Took away the entry->userinfo check from WHOIS
6478 reply sending. The entry->userinfo is now " " if client did not
6479 provide one. I thought this was fixed earlier but something
6480 is wrong still. Let's see if the error still appears.
6482 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6484 * Fixed a minor bug in the login when the channel key is
6485 re-generated in the server. It used to generate the key in
6486 wrong order and thus caused problems in the channel traffic.
6488 * Fixed a minor bug in channel key distsribution after
6489 KICK command. The key was not sent to the router even though
6492 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6494 * Added silc_ske_process_key_material_data as generic routine
6495 to process any key material as the SILC protocol dictates. The
6496 function is used by the actual SKE library but can be used by
6497 applications as well. This relates to the private message keys
6498 and the channel private keys since they must be processed the
6499 same way the normal SILC session keys. The protocol dictates
6500 this. Affected files: lib/silcske/silcske.[ch].
6502 Added also silc_ske_free_key_material to free the
6503 SilcSKEKeyMaterial structure.
6505 * Defined silc_cipher_set_key function to set the key for
6506 cipher without using the object's method function. The affected
6507 files: lib/silccrypt/silccipher.[ch].
6509 * Implemented silc silc_client_add_private_message_key,
6510 silc_client_add_private_message_key_ske,
6511 silc_client_del_private_message_key,
6512 silc_client_list_private_message_keys and
6513 silc_client_free_private_message_keys functions in the
6516 Added functions silc_client_send_private_message_key to send
6517 the Private Message Key payload and silc_client_private_message_key
6518 to handle incoming Private Message Key payload.
6520 * Added Cipher field to the Private Message Key payload to set
6521 the cipher to be used. If ignored, the default cipher defined
6522 in the SILC protocol (aes-256-cbc) is used.
6524 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6526 * Removed lib/silcclient/ops.h file.
6528 Redefined parts of the SILC Client Library API. Created new
6529 file silcapi.h that deprecates the ops.h file and defines the
6530 published Client Library API. Defined also private message key
6531 API and channel private key API into the file.
6533 This is the file that the application must include from the
6534 SILC Client Library. Other files need not be included by
6535 the application anymore.
6537 * Added new key_agreement client operation callback and also
6538 defined the Key Agreement library API for the application.
6540 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6542 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
6543 is used by clients to request key negotiation between another
6544 client in the SILC network. If the negotiation is started it
6545 is performed using the SKE protocol. The result of the
6546 negotiation, the secret key material, can be used for example
6547 as private message key.
6549 Implemented the Key Agreement payload into the files
6550 lib/silccore/silauth.[ch].
6552 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6554 * Redefined ciphers for the SILC protocol. Added some new ciphers
6555 and defined the key lengths for the algorithms. Changed the
6556 code accordingly. The default key length is now 256 bits.
6558 * Fixed SKE key distribution function silc_ske_process_key_material
6559 when the key length is more than 128 bits. The default key
6560 length in SILC is now 256 bits.
6562 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
6563 to indicate unsupported algorithm.
6565 * Renamed rijndael.c to aes.c and all functions as well.
6567 * Fixed a long standing channel key setting bug in client library.
6568 Weird that it has never surfaced before.
6570 * Fixed bug in channel deletion. If the entire channel is removed
6571 then it must also delete the references of the channel entry
6572 from the client's channel list as the client's channel entry and
6573 the channel's client entry share same memory.
6575 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6577 * Implemented CONNECT and SHUTDOWN commands in the client.
6579 * Implemented CLOSE command to the client.
6581 * Added the function silc_idlist_find_server_by_name into the
6582 files silcd/idlist.[ch].
6584 Added the function silc_idlist_find_server_by_conn into the
6585 files silcd/idlist.[ch].
6587 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6589 * DIE command was renamed to SHUTDOWN. Updated the both code
6592 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
6593 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
6595 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
6598 * Added function silc_server_create_connection function to create
6599 connection to remote router. My server implementation actually
6600 does not allow router to connect to normal server (it expects
6601 that normal server always initiates the connection to the router)
6602 so the CONNECT command is only good for connecting to another
6605 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6607 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
6608 or some other client was kicked from the channel.
6610 Implemented the handling of the notify type to both client
6613 Implemented silc_server_send_notify_kicked to send the KICKED
6614 notify. It is used to send it to the server's primary router.
6616 * Implemented the KICK command into server and client.
6618 * Added `query' argument to the silc_idlist_get_client function
6619 to indicate whether to query the client from server or not if
6622 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
6623 to indicate that the client is not channel founder.
6627 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6629 * Removed the rng context from SilcPacketContext structure and
6630 changed that the packet routine uses the Global RNG API.
6632 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6634 * Added support for quit message that client can "leave" on the
6635 channel when it quits the SILC. It is ditributed inside the
6636 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6638 Added silc_server_free_client_data that will take the
6639 signoff message as argument.
6641 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6643 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6645 * Updated parts of the protocol specification to keep it up
6648 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6650 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6651 payloads in one packet.
6653 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6654 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6655 use now the new List flag.
6657 * Also deprecated the following packet types: REPLACE_ID,
6658 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6660 * Added list support for Notify packet in server.
6662 * Added silc_server_send_notify_channel_change to send the
6663 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6664 the silc_server_send_replace_id.
6666 * Added silc_server_send_notify_nick_change to send the
6667 NICK_CHANGE notify type. Deprecates the function
6668 silc_server_send_replace_id.
6670 * Added silc_server_send_notify_join to send the JOIN notify type.
6671 Deprecates the function silc_server_send_new_channel_user.
6673 * Added silc_server_send_notify_leave to send LEAVE notify type.
6674 Deprecates the function silc_server_send_remove_channel_user.
6676 * Added silc_server_send_notify_cmode and
6677 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6678 types. Deprecates the silc_server_send_set_mode function.
6680 * Added SERVER_SIGNOFF notify type to indicate that server has
6681 quit. This means that all clients on the channel from that
6682 server will drop. This can be also used when netsplit happens.
6684 Deprecated REMOVE_ID packet type since it is not needed anymore
6687 Added silc_server_send_notify_server_signoff to send the
6688 SERVER_SIGNOFF notify type. Deprecates the function
6689 silc_server_send_remove_id.
6691 Added also silc_server_send_notify_signoff to send the
6692 SIGNOFF notify type.
6694 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6695 SILC protocol from this day on. Changed the protocol
6696 specification as well.
6698 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6699 notify type. It is used between routers to notify about
6700 topic changes on a channel.
6702 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6705 * Partly updated the protocol specification to comply with the
6706 changes now made. It is still though a bit outdated.
6708 * The JOIN notify type now takes one extra argument <Channel ID>.
6709 The packet used to be destined to the channel but now the
6710 JOIN type may be sent as list thus it is impossible to
6711 destine it to any specific channel. By adding this argument
6712 it is again possible.
6714 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6716 * Added CREDITS file. The CHANGES and CREDITS file will appear
6717 in the distribution as well.
6719 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6721 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6722 types in the server's silcd/packet_receive.c.
6724 * Implemented CMODE and CUMODE to work in router environment.
6726 * Fixed minor encoding and decoding buglet from the
6727 lib/silccore/silcmode.c.
6729 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6732 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6734 * Changed all SilcConfigServer* and silc_config_server* to
6735 SilcServerConfig* and silc_server_config*, respectively.
6738 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6740 * Associated the ID (client or server ID) to the Authentication
6741 Payload to avoid any possibility of forging. Updated the
6742 protocol specification and the code accordingly.
6744 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6746 * The RSA key length is now save to the RsaKey context in the
6747 key generation process in lib/silccrypt/rsa.c. The key length
6748 is now used to figure out the maximum size of the block allowed
6749 to be encrypted/signed.
6751 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6752 is equivalent to the silc_mp_mp2bin but does not allocate any
6755 * Changed silc_mp_mp2bin API to take length argument. If it is
6756 non-zero then the buffer is allocated that large. If zero, then
6757 the size is approximated using silc_mp_sizeinbase, which however
6760 * Created Global RNG API which is global RNG that application can
6761 initialize. After initializing, any routine anywhere in the
6762 code (including library) can use RNG without allocating a new
6763 RNG object. This was done to allow this sort of use of the
6764 RNG in code that has no chance to allocate RNG object. All
6765 applications currently allocate this and many routines in the
6766 library use this. Affected file lib/silccrypt/silcrng.[ch].
6768 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6769 it to use the Global RNG API.
6771 * Defined Authentication Payload into protocol specification that
6772 is used during SILC session to authenticate entities. It is
6773 used for example by client to authenticate itself to the server
6774 to obtain server operator privileges.
6776 Implemented this payload into the lib/silccore/silcauth.[ch].
6777 Implemented also routines for public key based authentication
6778 as the new protocol specification dictates.
6780 Moved definitions of different authentication methods from
6781 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6783 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6784 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6785 silc_pkcs_verify_with_hash functions into the file
6786 lib/silccrypt/silcpkcs.[ch].
6788 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6790 * The client entry's userinfo pointer must be always valid.
6791 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6792 will fail since it requires the userinfo. Now, the userinfo
6793 is allocated as "" if actual userinfo does not exist. Actually,
6794 it must exist and it is totally Ok to drop client connections
6795 that does not announce the userinfo. However, we will make
6796 this workaround for now.
6798 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6799 to return the remote port by socket.
6801 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6803 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6804 SILC_SERVER_PENDING_EXEC and added an new macro
6805 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6806 data or when error occurs while processing the pending command.
6808 Added new argument `destructor' into silc_server_command_pending
6809 and to the SilcServerCommandPending object. This destructor is
6810 now called after calling the pending callback or if error occurs
6811 immediately. If error occurs the actual pending callback won't
6812 be called at all - only the destructor. The destructor may be
6813 NULL if destructor is not needed.
6815 All this applies for client library code as well. Similar
6816 changes were made there as well for the pending commands.
6818 In the client, the application must now allocate the
6819 SilcClientCommandContext with the silc_client_command_alloc
6822 * Added reference counter to the SilcServerCommandContext. Added
6823 function silc_server_command_alloc and silc_server_command_dup
6826 Same type of functions added to the client library for the same
6829 * Removed the cmd_ident from IDListData away since it is now
6830 global for all connections. It is the command identifier used
6831 in command sending and with pending commands. The affected file
6834 * Added reference counter to the SilcSocketConnection objecet to
6835 indicate the usage count of the object. The object won't be
6836 freed untill the reference counter hits zero. Currently only
6837 server uses this, and client ignores it. The client must be
6838 set to use this too later. The affected files are
6839 lib/silccore/silcsockconn.[ch]. Added also the function
6840 silc_socket_dup to increase the reference counter.
6842 This was mainly added because it is possible that the socket
6843 is removed underneath of pending command or other async
6844 operation. Now it won't be free'd and proper DISCONNECTING
6845 flags, etc. can be set to avoid sending data to connection that
6846 is not valid anymore.
6848 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6849 the connection. After that it sets SILC_SET_DISCONNECTED.
6850 It is, however, possible that the socket data is not still freed.
6851 The silc_server_packet_process now checks that data is not
6852 read or written to connection that is DISCONNECTED. The socket
6853 get's freed when the reference counter hits zero.
6855 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6857 * Changed the client operation API: channel_message operation's
6858 `sender' is now the client entry of the sender, not the nickname
6859 and the `channel' is the channel entry, not the channel name.
6861 In the private_message operation the `sender' is now also the
6862 client entry of the sender not the nickname.
6864 Affected file is lib/silcclient/ops.h and all applications
6865 using the client operations.
6867 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6869 * Moved the calling of ops->connect() from connect_to_server_final
6870 into receive_new_id functin since that is the point when the
6871 client is actually allowed to send traffic to network. The
6872 affected file is lib/silcclient/client.c.
6874 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6876 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6877 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6878 (if needs broadcasting) instead of broadcasting the packets one
6879 by one which would make a burst in the network traffic.
6881 * Added `broadcast' argument to the functions in silcd/server.[ch]
6882 silc_server_create_new_channel[_with_id] to indicate whether
6883 to send New Channel packet to primary router.
6885 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6887 * Added new function into the silcd/server.[ch] files:
6888 silc_server_create_new_channel_with_id to create new channel with
6889 already existing Channel ID.
6891 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6892 lib/silccore/silcpacket.h. This packet is used t send list of
6893 Set Mode payloads inside one packet. Server uses this to set
6894 the modes for the channels and clients on those channels, that it
6895 announced to the router when it connected to it. The protocol
6896 specification has been updated accordingly.
6898 * The silc_server_new_channel did not handle the packet coming
6899 from normal server as it normally does not send that. However,
6900 when it announces its channels it does send it. Implemented
6901 the support for that.
6903 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6904 into the file lib/silccore/id.h.
6906 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6908 * Fixed memory leaks in the functions silc_idlist_del_client,
6909 silc_idlist_del_channel and silc_idlist_del_server in the file
6910 silcd/idlist.c. All of those leaked like a sieve.
6912 * Fixed some small memory leaks in the client's function
6913 silc_client_notify_by_server.
6915 * Added functions into silcd/server.c: silc_server_announce_clients,
6916 silc_server_announce_channels and silc_server_announce_server.
6917 These functions are used by normal and router server to announce
6918 to its primary router about clients, channels and servers (when
6919 router) that we own. This is done after we've connected to the
6922 These functions effectively implements the following packet types:
6923 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6924 and SILC_PACKET_NEW_ID_LIST.
6926 * Added new functions into the silcd/packet_receive.[ch]:
6927 silc_server_new_id_list, silc_server_new_channel_list and
6928 silc_server_new_channel_user_list to handle the incoming
6929 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6931 * Added support of changing Channel ID in the function
6932 silc_server_replace_id. If the server that announces a channel
6933 to the router already exists in the router (with same name but
6934 with different Channel ID), router is responsible to send
6935 Replace ID packet to the server and force the server to change
6936 the Channel ID to the one router has.
6938 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6939 client that the Channel ID has been changed by the router. The
6940 normal server sends this to the client. Client must start using
6941 the new Channel ID as the channel's ID.
6943 Implemented handling of this new type into lib/silcclient/client.c
6944 into the function silc_client_notify_by_server.
6946 * Added new function silc_idlist_replace_channel_id into the files
6947 silcd/idlist.[ch] to replace the Channel ID.
6949 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6951 * Call silc_server_command_identify_check always when processing
6952 the IDENTIFY command in silcd/command.c
6954 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6956 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6957 send keepalive packets. The packet can be sent by clients,
6958 servers and routers.
6960 Added function silc_socket_set_heartbeat into the file
6961 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6962 If not set, the heartbeat is not performed. The actual
6963 heartbeat is implemented in the low level socket connection
6964 library. However, application is responsible of actually
6967 Added silc_server_send_heartbeat to send the actual heartbeat
6968 packet into silcd/packet_send.[ch]. Server now performs
6969 keepalive with all connections.
6971 * Added silc_task_get_first function into lib/silcutil/silctask.c
6972 to return the timeout task with shortest timeout. There was a bug
6973 in task unregistration that caused problems. TODO has been
6974 updated to include that task system must be rewritten.
6976 * The client library will now resolve the client information when
6977 receiving JOIN notify from server for client that we know but
6978 have incomplete information.
6980 * Rewrote parts of silc_server_remove_from_channels and
6981 silc_server_remove_from_one_channel as they did not remove the
6982 channel in some circumstances even though they should've.
6984 * Encryption problem encountered in server:
6986 The LEAVE command used to send the Channel Key packet to the
6987 router immediately after generating it. However, the code
6988 had earlier sent Remove Channel user packet but not immediately,
6989 ie. it was put to queue. The order of packets in the router
6990 was that Channel Key packet was first and Remove Channel User
6991 packet was second, even though they were encrypted in the
6992 reverse order. For this reason, MAC check failed. Now, this
6993 is fixed by not sending the Channel Key packet immediately but
6994 putting it to queue. However, this is more fundamental problem:
6995 packets that are in queue should actually not be encrypted
6996 because packets that are sent immediately gets encrypted
6997 actually with wrong IV (and thus MAC check fails). So, packets
6998 that are in queue should be encrypted when they are sent to
6999 the wire and not when they put to the queue.
7001 However, the problem is that the current system has not been
7002 designed to work that way. Instead, the packet is encrypted
7003 as soon as possible and left to the queue. The queue is then
7004 just purged into wire. There won't be any fixes for this
7005 any time soon. So, the current semantic for packet sending
7008 o If you send packet to remote host and do not force the send
7009 (the packet will be in queue) then all subsequent packets to the
7010 same remote host must also be put to the queue. Only after the
7011 queue has been purged is it safe again to force the packet
7014 o If you send all packets immediately then it safe to send
7015 any of subsequent packets through the queue, however, after
7016 the first packet is put to queue then any subsequent packets
7017 must also be put to the queue.
7019 Follow these rules and everything works fine.
7021 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7023 * Added new function silc_server_remove_clients_by_server to
7024 remove all client entries from ID list when the server connection
7025 is lost. In this case it is also important to invalidate all
7026 client entires as they hold the invalid server entry. This
7027 fixes fatal bug when server has lost connection and will reconnect
7030 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7032 * Made some sanity checks to silc_server_daemonise like to check
7033 whether the requested user and group actually exists.
7035 * Added sanity check to SKE's silc_ske_responder_finish to check
7036 that the public and private key actually is valid.
7038 * Invalidate the client's nickname when receiving Replace ID
7039 packet and the Client ID is being replaced. This means that the
7040 server will query the nickname if someone needs it (client)
7043 * Sort the ID Cache in client library when the ID Cache data
7044 has changed (needs sorting).
7046 * Do not allow for SILC client to create several connections to
7047 several servers. The client does not support windows right now
7048 and generating multiple connections causes weird behaviour.
7050 Irssi-silc client does support windows and can handle several
7051 connections without problems, see: www.irssi.org and SILC plugin.
7053 * Fixed some places where client was added to the IDList. The
7054 rule of thumb is following (in order to get everything right):
7055 If the client is directly connected local client then the
7056 `connection' argument must be set and `router' argument must be
7057 NULL to silc_idlist_add_client function. If the client is not
7058 directly connected client then the `router' argument must
7059 bet set and the `connection' argument must be NULL to the
7060 silc_idlist_add_client function.
7062 * The funtion silc_server_packet_send_local_channel actually did
7063 not check whether the client was locally connected or not. It
7064 does that now. Fixed a bug related to LEAVE command.
7066 * Fixed Remove Channel User payload parsing bug in server's
7067 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
7069 * The server's silc_server_save_channel_key now checks also the
7070 global ID list for the channel as it might not be in the local
7071 list. Fixed a bug related to LEAVE command.
7073 * Is this the end of the [<unknown>] buglet that has been lurking
7074 around for a long time? A little for loop fix in server's
7075 silc_server_command_whois_parse that is used by both IDENTIFY
7076 and WHOIS command. At least, this was a clear bug and a cause
7077 of one type of [<unknown>] buglet.
7079 * WHOIS and IDENTIFY commands call the function
7080 silc_server_command_[whois/identify]_check function even if
7081 we are not router server.
7083 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7085 * Added --with-gmp configuration option. If set the GMP
7086 is always compiled in the SILC source tree. If not set then
7087 it is checked whether the system has the GMP3 installed. If
7088 it has then the GMP won't be compiled (the system's headers
7089 and library is used), if it doesn't have it then the GMP is
7090 compiled in the SILC source tree.
7092 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7094 * Changed RSA private exponent generation to what PKCS #1
7095 suggests. We try to find the smallest possible d by doing
7096 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
7097 not security fix but optimization.
7099 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7101 * Added new config entry [Identity] to fork the server and run
7102 it as specific user and group. A patch from Bostik.
7104 * Imported Dotconf configuration library into lib/dotconf.
7105 This will be used to create the SILC configuration files later.
7106 It will appear in the distsribution after this commit.
7108 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7110 * A big code auditing weekend happening. Auditing code for
7111 obvious mistakes, bugs and errors. Also, removing any code
7114 Removed files for being obsolete:
7116 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
7117 inline in the file lib/silcutil/silcbuffer.h)
7119 o lib/silcutil/silcbufutil.c (the header has inline versions)
7121 Changed code to fix possible error conditions:
7123 o The buffer formatting routines now check that the destination
7124 buffer really has enough space to add the data. This applies for
7125 both buffer formatting and unformatting
7126 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
7127 unformatting was changed to accomodate following rules:
7128 XXX_*STRING_ALLOC will allocate space for the data into the pointer
7129 sent to the function while XXX_*STRING will not allocate or copy
7130 the data into the buffer. Instead it sets the pointer from the
7131 buffer into the pointer sent as argument (XXX_*STRING used to
7132 require that the pointer must be allocated already). This change
7133 makes this whole thing a bit more consistent and more optimized
7134 (note that the data returned in the unformatting with XXX_*STRING
7135 must not be freed now). The routines return now -1 on error.
7137 o Tried to find all code that use buffer_format and buffer_unformat
7138 and added return value checking to prevent formatting and
7139 especially unformatting errors and possible subsequent fatal
7142 o Changed ske->x and ske->KEY to mallocated pointers in
7143 lib/silcske/silcske.h. Fixed possible data and memory leak.
7145 o Added return value checking to all *_parse* functions. Fixed
7146 many memory leaks as well.
7148 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
7149 so that buffer overflows would not happen. All code now also
7150 checks the return value as it can fail.
7152 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7154 * Added reconnection support to server if the normal server looses
7155 its connection to the router (for example if router is rebooted).
7156 The server performs normal reconnection strategy implemented
7157 to the server. Affected file silcd/server.c.
7159 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7161 * Added new packet type SILC_PACKET_SET_MODE that is used to
7162 distribute the information about changed modes (for clients,
7163 channels and clients channel modes) to all routers in the
7164 network. Updated the protocol specification accordingly.
7166 Added functions into silcd/packet_send.c and
7167 silcd/packet_receive.c: silc_server_send_set_mode,
7168 silc_server_set_mode.
7170 Added new files silcmode.[ch] into lib/silccore that implements
7171 the encoding and decoding of Set Mode Payload. Added new type
7172 SilcSetModePayload. Moved the definitions of different modes
7173 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
7175 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7177 * Oops, a little mistake in server's connection authentication
7178 protocol. The protocol is not ended with FAILURE but with
7179 SUCCESS if the authentication is Ok. :) Affected file is
7182 * Implemented NICK_CHANGE notify handling in server in the file
7183 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
7184 the local clients on the channel. After the changing nickname
7185 in router environment snhould work and the [<unknown>] nickname
7186 should appear no more.
7188 The silc_server_replace_id function that receives the Replace ID
7189 payload now sends the NICK_CHANGE notify type also in the file
7190 silcd/packet_receive.c
7192 * Changed WHOIS and IDENTIFY command to support the maximum amount
7193 of arguments defined in protocol specs (3328 arguments). This
7194 fixed a bug that caused problems when there were more than three
7197 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7199 * Added extra parameter, command identifier, to the
7200 silc_client_send_command so that explicit command identifier
7203 Changed that ID list routines uses specific command identifier
7204 when sending WHOIS/IDENTIFY requests to the server so that they
7205 can be identified when the reply comes back.
7207 Affected files lib/silcclient/command.[ch],
7208 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
7210 * Added `sender' argument to silc_server_packet_send_to_channel
7211 to indicaet the sender who originally sent the packet to us
7212 that we are now re-sending. Ignored if NULL. Affected file
7213 silcd/packet_send.[ch].
7215 * Added some server statistics support in silcd/server_internal.h
7216 SilcServerStatistics structure and around the server code. Also
7217 send some nice statistics information when client is connecting
7220 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7222 * Fixed channel ID decoding in server's JOIN command reply in
7223 silcd/command_reply.c
7225 * Fixed braodcasting of replace ID payload to not to send it if
7226 we are standalone server in silcd/packet_receive.c.
7228 * Fixed all channel message sending routines to not to send
7229 packets to clients that has router set, since they are routed
7230 separately in the same function earlier. Affects file
7231 silcd/packet_send.c and all channel packet sending functions.
7233 * In USERS reply, res_argv[i] are not allocated, the table
7234 is allocated. Thus changed that free the table, not its
7237 * In server's whois_check and identify_check if the client is
7238 locally connected do not send any WHOIS commands - they are not
7241 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7243 * Fixed some minor bugs in client when sending WHOIS command. The
7244 arguments was in wrong order.
7246 * Removed statis function add_to_channel from server in
7247 silcd/command.c that was previously used with the joining but
7250 * Tested USERS command in router environment successfully with two
7251 routers, two servers and two clients.
7253 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7255 * Reorganized the USERS command and command reply in client library
7256 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
7257 When the command is given by user we register a pending command
7258 callback that will reprocess the command after the reply has been
7259 received from the server. When reprocessing the packet we then
7260 display the information. Thus, the USERS information is displayed
7261 now in the command callback instead of in the command reply
7262 callback. The processing of the command is same as previously
7263 when server has sent the command reply in the JOINing process.
7265 * Added to USERS command in silcd/command_reply.c to join the client,
7266 we didn't use to know about, to the channel after we've created
7267 a client entry for it. Also, for clienet we did know already still
7268 check whether it is on the channel or not and add it if not.
7270 * Removed silc_server_command_join_notify as the function and its
7273 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7275 * Changed the client's pending command handling to the same as the
7276 server's pending command handling. It is also now possible to
7277 execute command reply functions from other command reply
7278 function as the function callbacks for commands and command
7279 replies are one and same. The pending commands are not static
7280 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
7281 in client connection context. Thus, pending commands are server
7282 connection specific as it is convenient.
7284 Changed the function silc_client_command_pending and
7285 silc_client_command_pending_del and added new function
7286 silc_client_command_pending_check. Removed the
7287 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
7290 * Added cmd_ident, current command identifier, to the client
7291 connection context in lib/silcclient/client.h to keep track on
7292 command identifiers used in command sending. Client's command reply
7293 function handling now supports the mandatory command identifiers.
7295 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
7296 funtions in client to fully support pending command callbacks.
7298 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
7299 as one of the arguments to the application in the command reply
7302 * NOTE: The FORWARDED flag is depracated. It used to be depracated
7303 before first releasing SILC but came back. Now it is removed again
7304 and should come back nomore. The FORWARDED flag was used only
7305 by the JOINing procedure by forwarding the command packet to router.
7306 Now, the JOINing procedure has been changed to more generic (due
7307 to various router environment issues) and FORWARDED is not needed
7308 anymore for anything. The protocol specification is yet to be
7311 Now, removed silc_server_packet_forward from server and the flag
7312 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
7314 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7316 * Renamed NAMES command to USERS command. The NAMES was named that
7317 due to historical reasons. Now it is renamed. Also, rewrote
7318 parts of the USERS command. The nickname list is not sent anymore
7319 by the server. Only Client ID and mode lists are sent in the USERS
7320 command. Changed this also to the protocol specification.
7322 The client now resolves the names and stuff after it receives
7323 the USERS list from the server when joining to the channel.
7325 * WHOIS and IDENTIFY commands has been changed to support multiple
7326 Client ID's per command. One can now search for multiple users
7327 in the network by sending only one WHOIS or IDENTIFY command.
7328 Changed the code and the protocol specifications.
7330 * Removed silc_server_command_identify_parse and changed that IDENTIFY
7331 uses silc_server_command_whois_parse to parse the request. */
7333 * If normal server, do not parse the WHOIS and IDENTIFY requests
7334 before sending it to the router. Saves some time.
7336 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7338 * Fixed JOIN command on client library. Wrong number of arguments
7339 used to crash the client.
7341 * Added silc_server_channel_has_global function to check whether
7342 channel has global users or not.
7344 * Added silc_server_channel_has_local function to check whether channel
7345 has locally connected clients on the channel.
7347 * The silc_server_remove_from_one_channel now checks whether the
7348 channel has global users or not after given client was removed from
7349 the channel. It also checks whether the channel has local clients
7350 on the channel anymore. If it does not have then the channel entry
7351 is removed as it is not needed anymore.
7353 * The silc_server_notify now checks on JOIN notify whether the joining
7354 client is one of locally connected or global. If it is global then
7355 the channel has now global users on the channel and that is marked
7356 to the channel entry. Also, it now saves the global client to
7357 global list who is joining and JOINs it to the channel. This is
7358 for normal server, that is.
7360 Changed silc_server_send_notify_on_channel,
7361 silc_server_packet_relay_to_channel and
7362 silc_server_packet_send_to_channel check if we are normal server
7363 and client has router set (ie. global client) do not send the
7364 message to that client, as it is already routed to our router.
7366 * Implemented LEAVE notify type handling in silc_server_notify
7369 * Tested LEAVE command in router environment successfully. Tested
7370 with two routers, two servers and two clients.
7374 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
7376 * Implemented SIGNOFF notify type handling in silc_server_notify
7379 * silc_server_remove_id now removes the client entry from all channels
7380 it has joined and thusly sends SIGNOFF notify type.
7382 * Rewrote the NAMES list generation in server by removing two excess
7383 loops. The lists are created now inside one loop.
7385 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7387 * silc_server_remove_channel_user checks now also global list
7388 for channel and client.
7390 * silc_server_new_channel_user checks now both local and global
7391 list for channel and client. Fixed a bug in client id decoding.
7392 Used to decode wrong buffer.
7394 * silc_server_channel_message checks now both local and global
7395 list for channel entry.
7397 * Tested channel joining (hence JOIN) in router environment
7398 successfully. Tested with two routers, two servers and two
7401 * Tested channel message sending in router environment successfully.
7403 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7405 * Added silc_server_save_channel_key into server.[ch] to save the
7406 received channel key in Channel Key payload processing. It is
7407 also used in JOIN command reply handling.
7409 Equivalent function silc_client_save_channel_key added into
7410 client.[ch] into client library.
7412 * Changed JOIN command reply to send information whether the channel
7413 was created or not (is existing already) and the channel key
7414 payload. Changed protocol specs accordingly.
7416 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
7417 the request was sent by ID and not by nickname. Crashed on
7420 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7422 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
7423 now correctly save the received data.
7425 * silc_server_free_sock_user_data now notifies routers in the
7426 network about entities leaving the network.
7428 At the same time implemented functions silc_server_remove_id
7429 and silc_server_send_remove_id to receive and send REMOVE_ID
7430 packets. The packet is used to notify routers in the network
7431 about leaving entities. The ID removed will become invalid in
7434 * Added function silc_idlist_del_server into server. Removes and
7435 free's server entry from ID list.
7437 * silc_server_private_message function now checks, if we are router,
7438 that the destination ID really is valid ID, naturally.
7440 * In router when NEW_ID packet is received (for new client) the
7441 hash of the Client ID is saved in the ID Cache but the
7442 client->nickname is set to NULL, instead of putting the hash
7445 IDENTIFY command now also checks that client->nickname must be
7446 valid. If it is not if will request the data from the server who
7447 owns the client. Added new function
7448 silc_server_command_identify_check.
7450 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
7451 to set the command to already allocated Command Payload.
7453 * Tested private message sending in router environment with two
7454 routers, two servers and two clients. Fixed minor bugs and now
7457 * Fixed segfault from client's NAMES command. Used to crash if
7460 * Forwarded packets must not be routed even if it is not destined
7461 to the receiver. Changed server code comply with this.
7463 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7465 * Added `require_reverse_mapping' boolean value to ServerParams
7466 structure. If TRUE (not default) the server will require that
7467 the connecting host has fully qualified domain name.
7469 If the reverse mapping is not required and hostname could not be
7470 found the IP address is used as hostname.
7472 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7474 * Implemented version string checking to both client and server.
7475 The check is incomplete currently due to the abnormal version
7476 strings used in development version of SILC.
7478 * Changed all command functions in server to use the new
7481 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7483 * Changed char *data to unsigned char *data in ID Cache system to
7484 support binary data as ID Cache data. Changed code to support
7485 binary data in lib/silccore/idcache.c.
7487 * Renamed silc_server_packet_relay_command_reply to
7488 silc_server_command_reply as it is normal packet receiving
7489 function. Rewrote the function to accept command replys for
7490 servers and not only for clients.
7492 * Mark remote router always as registered server if we are connecting
7493 to it. Otherwise, commands sent by the router to us are ignored.
7495 * All ID List find routines now returns the ID Cache Entry pointer
7496 as well if requested.
7498 * WHOIS command works now in router environment, tested with two
7499 routers, two servers and two clients.
7501 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
7502 in router environment (as it is almost equivalent to WHOIS) but
7503 hasn't been tested thoroughly. Added new functions:
7505 silc_server_command_identify_parse
7506 silc_server_command_identify_send_reply
7507 silc_server_command_identify_from_client
7508 silc_server_command_identify_from_server
7510 * Disabled route cache adding because adding two different ID's with
7511 same IP replaces the old cache entry thus giving wrong route.
7512 The entry->router->connection is always the fastest route anyway
7513 so route cache may not be needed. Of course, new routes maybe
7514 established after receiving the ID when the entry->router->connection
7515 might not be anymore the most optimal.
7517 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7519 * Add route cache for received ID for fast routing.
7521 * Added silc_server_packet_route to route received packet on router
7522 that is not destined to us.
7524 * Renamed silc_server_get_route to silc_server_route_get.
7526 * Added id_string and id_string_len fields into SilcServer to
7527 include encoded ServerID for fast comparing without excess
7528 encoding of the ID's.
7530 * Cleaned up WHOIS command on server side. Added following static
7533 silc_server_command_whois_parse
7534 silc_server_command_whois_check
7535 silc_server_command_whois_send_reply
7536 silc_server_command_whois_from_client
7537 silc_server_command_whois_from_server
7539 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
7540 arguments in command replies. All command functions should be
7541 updated to use this macro.
7543 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7545 * Minor typo fixes on command reply handling on server.
7547 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7549 * Added silc_server_command_add_to_channel internal routine to add
7550 the client to the channel after router has created the channel and
7551 sent command reply to the server.
7553 * Added generic silc_server_send_command to send any command from
7556 * Use static buffer with ID rendering instead of duplicating data.
7558 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7560 * Fixed a channel user mode bug when joining to a channel server gave
7561 everybody channel founder rights, oops.
7563 * We mark ourselves as the router of the incoming server connection
7564 if we are router ourselves. This way we can check in some packet
7565 sending functions whether it is locally connected server. For
7566 incoming router connections we put NULL.
7568 * For router sending packets locally means now always sending the
7569 packet cell wide; to local clients and local servers. For normal
7570 server sending packet locally means sending it to only local
7573 * Fixed the JOIN command to really work in router environment. If the
7574 channel is created it is always created by the router. Router is
7575 also responsible of making the initial joining to the channel,
7576 sending JOIN notify to the sending server and distributing
7577 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
7578 does not exist server doesn't do anything else but forward the
7579 command to the router which performs everything.
7581 * Added silc_server_send_channel_key function to send the Channel Key
7584 * Added silc_server_create_channel_key to create new channel key. The
7585 channel key is now re-generated everytime someone joins or leaves
7586 a channel, as protocol dictates. Note: channel->key_len is the
7589 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7591 * Splitted server.[ch] finally. Created now packet_send.[ch] and
7592 packet_receive.[ch] to separate packet sending and receiving
7593 routines. The server.[ch] now includes everything else including
7594 actual packet processing (writing and reading data) and other
7597 Renamed silc_server_private_message_send_internal to
7598 silc_server_send_private_message. The routine is still though
7599 used only to relay private messages as server does not send
7600 private messages itself.
7602 Renamed silc_server_new_channel to silc_server_create_new_channel
7603 and added new function sicl_server_new_channel that handles the
7604 incoming New Channel packet. Added also new sending function
7605 silc_server_send_new_channel to send New Channel Payload.
7607 * Added new function silc_server_notify to process incoming notify
7608 packet to the server/router. Server may then relay the notify
7609 to clients if needed.
7611 * Added new function silc_server_new_channel_user to process incoming
7612 New Channel User packet. Router will redistribute the packet and
7613 send JOIN notify to its local clients and locally connected servers
7614 if needed. Normal server will send JOIN notify to its local client
7615 on same channel when received this packet. Added also corresponding
7616 sending function silc_server_send_new_channel_user to sent the
7619 * Added boolean route argument to send_notif_to_channel and
7620 packet_send_to_channel functions to attempt to route the packet
7621 if it is TRUE and send only locally if it is FALSE.
7623 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7625 * silc_server_replace_id now broadcasts the received replace ID
7626 packet if it is not broadcast packet already. The router must
7627 broadcast to inform other routers about changed ID.
7629 * Added backpointer to server's router into SilcServer context in
7630 silcd/server_internal.h.
7632 * Fixed silc_server_packet_broadcast to send correct broadcast
7635 * The channel key is now distributed to the local client as soon
7636 as it is received from the router (in router environment) so that
7637 no other packet may be sent for the channel until client has
7640 * silc_server_remove_channel_user now broadcasts the received
7641 Remove Channel User packet if it is not broadcast packet already.
7642 The router must broadcast to inform other routers about removed
7645 * Added users field into SilcPacketContext that is a reference count
7646 of the context. One can increase the reference count by calling
7647 silc_packet_context_dup which is now changed to just increase the
7648 reference count instead of duplicating the data. The reference
7649 count is decresed by calling silc_packet_context_free that will
7650 free the data after the reference count hits zero.
7652 For now on the packet context and everything allocated into it
7653 (including the raw packet from network) must be freed by calling
7654 the new silc_packet_context_free function. Added also new function
7655 silc_packet_context_alloc that must be used now to allocate the
7656 context. This also means that if a routine is asynchronous from
7657 silc_[client/server]_packet_parse_type the packet context must
7658 be duplicated by calling silc_packet_context_dup. Otherwise it
7659 gets free'd after silc_[client/server]_packet_parse_type returns.
7660 Also, one must remember that if packet is duplicated then its
7661 reference count must be decresed by calling the free function as
7662 many times as it was duplicated.
7664 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7665 from both client and server.
7667 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7669 * Made joining to a channel working in router environment.
7671 * Cleaned up JOIN command on server side and create function
7672 silc_server_command_join_channel internal routine to make the
7675 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7677 * Changed silc_command_pending list to SilcDList. Also, added
7678 `ident' field to SilcServerCommandPending structure to identify
7679 the reply and to call correct callback.
7681 Added silc_server_command_pending_check function to replace the
7682 corresnponding macro. The silc_command_pending list is not
7685 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7686 to set identifier to previously allocated Command Payload. It
7687 is used to set identifier for command when resending Command
7690 * Added silc_command_payload_encode_payload to encode Command
7691 Payload buffer from SilcCommandPayload structure.
7693 * Added silc_argument_payload_encode_payload to encode Argument
7694 payload buffer from SilcArgumentPayload structure.
7696 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7698 * Changed WHOIS command to support router connection on server side.
7699 The whois request is always sent to router unless the server is
7700 standalone server. After server has received the reply from the
7701 router will it send the reply to the client.
7703 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7704 broadcast received broadcast packet. The function is used only
7705 by router. The broadcast packet is always sent to the router's
7708 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7709 render given ID to printable string, for log files for example.
7711 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7713 * Made basic router to router connections working. At least they
7714 can now connect to each other but nothing really works the way
7715 they are supposed - yet.
7717 * Added new initiator token to RouterConnection configuration
7718 file in silcd/serverconfig.[ch]. It is used to tell whether we
7719 are the initiator to the remote router or whether we'll expect
7720 the other end to connect.
7722 * Moved registering of listener task to silc_server_init, hence
7723 the server starts listenning as soon as it is run, even if it
7724 does not have connections to other routers. Let's see how well
7727 * Changed default connection retry timeouts for more suitable in
7730 * Removed cipher and such arguments from silc_idlist_add_client
7731 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7732 Added new function silc_idlist_add_data to add the keys and stuff
7735 * Added SilcIDListData structure and added it to SilcClientEntry
7736 and SilcServerEntry as their first field in the structure. This
7737 way we can explicitly cast the ID entries to the SilcIDListData
7738 structure and get common data for the entries. In past, we had
7739 to first check what type of connection it is and then cast it to
7740 correct ID entry type. Now, we can directly cast the opaque
7741 pointer to the SilcIDListData (no matter what ID entry it actually
7742 is) and get the data needed.
7744 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7746 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7747 in some circumstances even if threre were timeout tasks, though not
7748 IO tasks, but tasks anyway. Now fixed.
7750 * Defined SilcServerConnection structure to hold connection specific
7751 stuff about directly connected servers and routers. The definition
7752 is currently in silcd/server_internal.h. I thought about having
7753 a bit more important role fro this struct but for now it is used
7754 only when connecting to other server (or router actually).
7756 * Added connecting retry support in server when connecting to
7757 router(s). The retry feature implement exponential backoff
7758 algorithm. Also, added SilcServerParams structure to hold default
7759 parameters for server. For now, it include these retry settings
7760 and are hard coded. After server is moded to be as Silc Server
7761 Library this structure will be more important.
7763 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7765 * Changed client librarys channel->clients table to SilcList and
7766 changed code accordingly.
7768 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7770 * Changed client's channel table to SilcList and changed code
7771 accordingly. Also changed SilcChannelClientEntry to include back-
7772 pointer to the channel so that client entry can use that structure
7773 as list as well and we have fast cross-reference to the channel.
7774 This change dramatically decreased the complexity of channel
7775 handling with client entry and vice versa (removed one extra
7776 loop when searching for channel entry from many functions).
7778 * Changed server->sim from table to SilcDList and changed code
7781 * NAMES command can now be used from user interface. It will show
7782 the user list on the channel, neatly.
7784 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7785 Code now saves realname of the user if it becomes available.
7787 * Renamed configure.in to configure.in.pre and made ./prepare
7788 script to automatically add correct version string to
7789 configure.in which it creates from configure.in.pre.
7791 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7793 * NAMES command reply now shows users mode with the nickname when
7796 * Moved silc_client_ch[u]mode[_char] functions from
7797 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7798 place sucks, they are utility functions and should be in some
7801 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7803 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7806 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7810 * Added TRQ (efficient deque and list library) into lib/trq. This is
7811 a very good list library that is currently used in the SILC. Defined
7812 SilcList API over the library because I didn't like the API very
7813 much. See lib/trq/silclist.h for the API and examples of how to
7814 use the API. Fixed various places in the code to use the new
7815 SilcList API. The SilcList is meant for lists that has a structure
7816 already defined as a list. It is not suitable to add just some
7817 context to the list (in TRQ, the context is the list actually).
7819 So, I defined SilcDList that can be used for the purpose where
7820 predefined list structure does not exit. This can be used as
7821 such list. Now some context just can be added to the SilcDList.
7822 Currently this list is not used in the SILC just yet, though there
7823 are a lot places where this can replace dynamically allocated
7824 tables and I will fix these places, later, to use SilcDList.
7825 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7826 and use TRQ internally).
7828 Also fixed some annoying warning messages that the original TRQ
7829 code generated. Also minor changes to TRQ's Makefile.in.
7831 * Added support for querying by Client ID to both WHOIS and
7832 IDENTIFY commands into server, as required by the protocol.
7834 * Removed method function pointers from SilcBuffer structure. They
7835 weren't used to anything and just increased the context size for
7836 no good reason. This change also made silc_buffer_alloc and
7837 silc_buffer_free functions inline functions.
7839 * Disabled command flooding detection support until it's fixed so
7840 that it accepts commands in but does not execute them more than once
7843 * Added silc_net_localhost(), to return local hostname, into
7844 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7845 that must be initialized before calling silc_client_init.
7847 * Added new function: silc_server_send_notify_on_channels to send
7848 notify messages to all channels client has joined. It is assured
7849 that the message is sent only once per client.
7851 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7852 lib/silcutil/silcutil.[ch] as silc_format function. The new
7853 function is generic and is used by server as well, not only by
7854 the logging routines.
7856 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7857 the provided version string was not acceptable. Added new function:
7858 silc_ske_check_version into lib/silcske/silcske.h. The function
7859 must be implemented by the application (client or server) and it
7860 does not reside in the SKE library. The function checks the version
7861 string remote end sent.
7863 * Added back pointers (to opaque context and to SilcSocketConnection)
7864 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7866 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7867 duplicate packet context structure.
7869 * Changed `notify' client operation to send same arguments as client
7870 receives from server except for ID's. ID's are mapped to correct
7871 ID entry and that is returned. Also, if channel entry is not sent
7872 by server but the notify is for channel the channel entry is sent
7873 to application (otherwise application doesn't know that it is for
7874 channel (library gets it from packet's Destination ID)).
7876 * Added silc_client_remove_from_channels into client library to
7877 remove a client from all channels it has joined to. Used when
7878 received SIGNOFF notify from server. Added also new function
7879 silc_client_replace_from_channels to replace old ID entry with
7880 new ID entry on all channels. Used when received NICK_CHANGE
7883 * Fixed ID Cache list handling in silc_idlist_get_client in
7884 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7885 to get (or query) client by ID.
7887 * Updated TODO list.
7889 * Added connection authentication status message defined by the
7890 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7891 support for these into the code in client and server side.
7893 * Added generic function silc_client_send_command to send any command
7894 with variable argument list. Application should use this function
7895 to send commands if the command functions provided by the library
7896 does not suite for the application's user interface needs.
7898 * Added new `failure' client operation. Application is notified about
7899 received failure packet if client is executing a protocol. In this
7900 case the protocol's execution has failed.
7902 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7903 is required by the protocol.
7905 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7906 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7909 * Added status flag to SilcSKE object to indicate realtime status
7910 of the SKE protocol.
7912 * Application receives now exactly same command reply arguments as
7913 the library receives from server. However, if ID is received the
7914 corresponding ID entry is returned to the application (eg. Client
7915 ID is mapped to correct SilcClientEntry entry and that is returned).
7916 Changed command_reply client operation due to this change.
7918 * Changed all ID's in commands and in command replys as ID Payloads.
7919 Change affected both client and server side codes.
7921 All ID's sent in SILC network (with execption of ID's in SILC
7922 Packet header) are sent in ID Payload to support variable length
7925 * Server now notifies nick changes and notifies all clients on
7926 the channels about the new nickname (about the new Client ID,
7929 * Implemented CMODE command to change channel modes. Supports all
7930 channel modes defined by the protocol specs except ban and invite
7931 lists. (Also, private channel key mode is supported but support for
7932 setting private channel key in client is missing, thus, this mode
7933 has no effect on client side (except that server requires that the
7934 client uses private channel key and normal channel traffic does not
7937 Also, invite mode works per se, but INVITE command does not work
7938 yet correctly, so you can set channel as invite only channel but
7939 inviting clients to the channel does not work (it is yet to be
7940 thought what's the best way to do it).
7942 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7943 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7944 Implemented CUMODE command to change user's mode on the channel.
7945 Supports all modes defined by the protocol specs.
7947 * Added NAMES command reply to return users modes on the channel.
7949 * Removed unnecessary and slow ciphers from lib/silccrypt.
7951 * Set SO_KEEPALIVE option to connection sockets by default.
7953 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7955 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7956 redefined the Notify Payload into protocol specs.
7958 * Added silc_id_payload_parse_id to get ID directly from raw
7961 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7963 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7964 accept searching by Client ID as well.
7966 * Added support for LEAVE and SIGNOFF notify types in client library.
7968 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7969 to parse ID Payload from raw data.
7971 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7973 * Added flags parameter into silc_ske_assemble_security_properties
7974 function in lib/silcske/silcske.[ch].
7976 * Changed notify client operation to fit better for notify messages
7977 sent by server. The notify payload received from server is now
7978 passed to the application (after parsing it to SilcNotifyPayload).
7979 It is application's responsibility to retrieve the arguments
7980 from the payload and show the message the way it wants. The message
7981 sent by server is implementation specific.
7983 * Changed public keys to comply with the protocol specification.
7984 Old public keys are not supported anymore and are not compatible.
7986 * Removed nickname from Channel Payload as the latest draft removed
7987 it. The client must resolve the nickname from the NAMES command
7988 reply received when it joined the channel.
7990 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7992 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7994 * Fixed some errors in protocol specification drafts.
7996 * Created lib/silccore/silcnotify.c to implement Notify Payload
7997 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7998 generic payloads described by protocol specifications. The file
7999 includes implementations for ID Payload and Argument Payload.
8001 * Changed Command Payload implementation to use the new Argument
8002 Payload. Changed command_xxxx_payload to command_payload_xxxx
8003 to comply with SILC coding conventions.
8005 * Added suppport for Argument Payload handling in Notify Payload
8006 implementation as protocol requires it. Added the new support
8007 into server and client lib as well.
8009 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8011 * Added support for multiple nicknames on same channel. [n] is
8012 added locally to the nickname if there are more than one same
8013 nicknames on the channel.
8015 * Server now sends all nicknames that matched WHOIS request.
8016 Client also shows the list received from server.
8018 * Added TOPIC command to client side. User can now set and show
8019 current topic on channel.
8021 * Added MOTD command to client and server. Also, server sends the
8022 motd when client connects to the server.
8024 * Changed version strings to comply ISO 8601.
8026 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8028 * Fixed protocol error handling in client library. It should now
8029 cope even if the SKE fails for some reason.
8031 * Made new protocol specification drafts for submitting to IETF.
8033 * Implemented TOPIC command to server in silcd/command.c.
8035 * Added two new notify types into lib/silccore/silcnotify.h:
8036 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
8037 notify nickname change and topic setting/change on a channel.
8039 * API change of command_reply operation in client library. The
8040 application gets now the status type received from server as well.
8042 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8044 * Removed the function just added to lib/silcutil/silcschedule.[ch].
8046 * Cras fixed and optimized the packet handling even further and
8047 it should work now. Minor change to the prototype of function
8048 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
8050 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8052 * Added new function into lib/silcutil/silcschedule.[ch]:
8053 silc_schedule_with_fd to select() a specified fd. The function
8054 returns after timeout expires or data arrives or goes. The
8055 function is used by packet routines to wait that all data is
8056 received from network.
8058 * Fixed data reading from network in lib/silccore/silcpacket.c.
8059 The code now assures that all data is read from the fd and then
8060 continues packet processing. This was a bug fix since the code
8061 used to drop some data in some circumstances.
8063 * Added new function into lib/silcclient/client.[ch]:
8064 silc_client_start_key_exchange to start key exchange after
8065 connection has been established to server. The code internally
8066 now uses this funtion but its main purpose was to provide it
8067 for applications that perform their own connecting. After
8068 application has created a connection it merely calls this
8069 function to start the key exchange between client and server.
8070 The library takes care of everything else after that.
8072 Updated also lib/silcclient/README to explain the usage of
8075 * Do not send to application information that connection has
8076 been established. Application gets notified it by connect
8079 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8081 * Applied cras's patch to add silc_schedule_one function. The
8082 function runs scheduler once and returns.
8084 * Fixed the scheduler after cras messed it up. The timeout
8085 handling works now as it's supposed to work.
8087 * Added into lib/silccore/ silcnotify.h to include notify
8088 message types support. Changed silc_server_send_notify*
8089 functions, in server.[ch], to support those new notify types.
8090 Added the support for the notify types into client library,
8091 as well. Added new notify client operation into ops.h in
8094 * Changed silc_server_packet_send_to_channel to send normal
8095 packets instead of just channel message packets. The function
8096 is now used to send the notify packets to channels. It is not
8097 used to send channel message packets anymore, as server never
8100 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
8101 va_arg()s as it seems to require it nowadays. I guess, if SILC
8102 is compiled with older va_arg() the new code should work anyway.
8104 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8106 * Splitted core library. Core library (lib/silccore) includes
8107 now only SILC protocol specific core (and common) components.
8108 Created new utility library (lib/silcutil) that includes more
8109 generic purpose stuff. The stuff for util library was taken
8110 from the old core library. This was minor and easy split.
8112 * Created SILC Client Library (lib/silcclient) that includes
8113 implementation of the SILC client without user interface. This
8114 was major move from silc/ directory. The code has been changed
8115 so that it is transparent towards the user interface. The
8116 silc/ directory includes now the same user interface as before
8117 and it uses the new client library. Read lib/silcclient/README.
8118 Basicly, the client library performs everything else related
8119 to SILC except user interface handling. Also, configuration
8120 files are considered to be part of user interface and library
8121 does not handle them.
8123 This change also changed a lot of structures, function naming etc.
8124 Most important change was that SilcClientWindow object was
8125 renamed to SilcClientConnection in the client library. Created
8126 also new file lib/silcclient/ops.h. Also added new files
8127 silc/local_command.[ch] and silc/client_ops.[ch].
8129 All these changes were made to make it easier for user interface
8130 designers to create what ever user interface for the SILC client
8133 It is also expected that the server will be moved to lib
8134 directory as well and SILC Server Library will be created;
8135 sometimes in the future.
8137 * Removed Local commands from lib/silccore/silccommand.h as
8138 they are application specific and new client library does not
8139 handle any of those anymore.
8141 * Several functions moved to lib/silcutil/silcutilc.[ch] from
8142 old client implementation in silc/.
8144 * Added support for callback functions in SILC_LOG_* macros.
8145 Application can now set its own callbacks that will be called
8146 instead of using the default functions that will always print
8147 the debug messages to stderr (or stdout). Also, debugging can
8148 now be disabled by setting silc_debug to FALSE and re-enabled by
8149 setting it to TRUE. Note, that logging will still work even
8150 if debugging is disabled.
8152 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
8153 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
8154 silc_log_reset_debug_callbacks.
8156 * To enable debugging in silc client one must give now -d
8157 option on command line.
8159 * Changed silc_schedule_init to automatically allocate task queues
8160 if they are not allocated before calling it.
8162 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8164 * Added GMP 3.1 into math library.
8166 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8168 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
8169 a channel in SILC network. The packet is used by servers and
8170 routers to notify other routers that user has left a channel.
8171 This little feature was missing until now. Added the feature
8172 to protocol specification as well.
8174 Added functions: silc_server_send_remove_channel_user and
8175 silc_server_remove_channel_user into server.[ch].
8177 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
8178 lib/silccore/silcpacket.h. However, they are not implemented
8181 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8183 * Fixed joining to a channel and sending channel messages
8184 between server and router. The channel message sending should
8185 now work inside a cell.
8187 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8189 * Fixed the private message sending between server and router.
8190 The private message sending should now work inside a cell.
8192 * Added silc_server_replace_id into server.[ch] to replace
8193 existing ID in the SILC network.
8195 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
8196 and silc_idlist_replace_server_id into idlist.[ch] in server.
8198 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8200 * Fixed the server to server connections. Server can again now
8201 connect to router. Router to router connections probably does
8204 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8206 * Added dynamic protocol registering support. Now protocols can
8207 registered and unregistered on the fly. Patch by cras.
8209 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8211 * Added lib/contrib directory to hold routines that some platforms
8212 don't have but are needed by SILC.
8214 * Added getopt.c, getopt1.c and getopt.h from GNU C library
8215 into lin/contrib to provide getopt() and getopt_long() for
8216 those who don't have it.
8218 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8220 * Added AWAY command to client. When away message is set and
8221 client receives a private message packet the client automatically
8222 replies to the sender with the away message.
8224 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
8225 bug seemed to be the cause of recent problems when compiling
8228 * Added version detection support to SKE protocol specification
8229 and added the new changes to the SKE implementation as well.
8230 There were other minor changes in the SKE protocol as well.
8232 Many changes in lib/silcske/silcske.[ch] and in
8233 lib/silcske/payload.[ch].
8235 * Added ^U functionality, clear input line. Patch from cras.
8237 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8239 * Mainly small bugfixes on core library. Fixed some debugging
8240 logging and buffer overflow in silclog.c.
8242 * Updated config.sub and config.guess on the distribution tree.
8244 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8246 * Added command lagging support in server. Client may execute
8247 commands now only once in two seconds.
8249 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8251 * Optimized packet reception. MAC computation and checking is now
8252 also more optimized. A lot previously duplicated code is now
8253 used as generic by both client and server.
8255 * Fixed key pair generation in clientutil.c
8257 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8259 * Added into lib/silccore/silcbufutil.[ch] new function;
8260 silc_buffer_realloc.
8262 * Moved generic packet sending/encryption functions to
8263 lib/silccore/silcpacket.[ch] from client and server. Some
8264 rewriting of the functions.
8266 * Moved all generic packet reception/decryption functions to
8267 lib/silccore/silcpacket.[ch] from client and server. The
8268 packet processing is now much cleaner in both client and server.
8269 These were major changes in both client and server.
8271 * Created many common functions in server to do packet sending.
8272 Previously code were duplicated a lot, this has been removed
8275 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8277 * Rewrote major parts of the ID cache system. Don't know
8278 whether it is better now or not but at least the API is more
8281 * Major rewrite on ID cache stuff on client because of the ID
8282 cache API changes. Added idlist.c to client.
8284 * Also major rewrite on ID cache stuff on server as well.
8285 Major rewrite of idlist.[ch]. SilcXXXList's are now named
8286 SilcXXXEntry's. We won't keep anymore idlist specific pointers
8287 in hand, instead they are all put into the ID cache system now.
8288 All server_idlist_* routines uses ID cache now instead of
8289 traversing its own lists (those lists does not exist anymore).
8290 SilcIDList though still exists. Also, SilcXXXEntry's are
8293 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8295 * Finally made the SKE implementation compliant to the protocol
8296 specification. All mp integers are now binary encoded as
8297 opposed being HEX encoded.
8299 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
8302 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
8303 functions: silc_[encode/decode]_pem. Also added function
8304 silc_encode_pem_file to PEM encode with newlines ('\n') for
8307 * SILC public keys are now encoded either PEM or binary. Same
8308 option is for private keys as well. By default private keys
8309 are binary encoded and public keys PEM encoded. Silly HEX
8310 encoding were removed.
8312 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
8313 function to create fingerprints.
8315 * Fixed a bug in SHA1; does not change the original data anymore.
8317 * Partly implemented INFO command on client and server side.
8318 Fixed CLEAR command. Changes to SERVER command; show current
8319 server(s) when giving command without arguments. Added
8320 VERSION command to client.
8322 * Added check to server that unregistered connections cannot
8323 execute commands (unless it is specificly allowed).
8325 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8327 * Fixed screen refresh.
8329 * Fixed channel joining bug from client. On some circumstances
8330 client tried to join to a channel it had already joined.
8332 * Added public key verification process into client's protocol.c.
8333 The client now verifies the public key from user and saves
8334 it into ~./silc/serverkeys/ directory.
8336 Added into: clientutil.[ch]: silc_client_verify_server_key.
8338 * Changed SKE protocol's silc_ske_initiator_finish function
8339 to accept callback function that verifies the received public
8340 key. Removed old silc_ske_verify_public_key function.
8342 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8344 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
8345 silc_pkcs_private_key[_data]_set.
8347 * Made the password and public authentication more cleaner in
8348 server's protocol.c.
8350 * Removed historic and obsolete protocol `channel_auth' from
8351 both client and server.
8353 * Removed wrong way of sending command status messages from
8354 server to client in server's command.c. The old way violated
8355 protocol specification.
8357 Changes to silccore/silccommand.[ch]: removed
8358 silc_command_encode_status_payload -> not needed anymore,
8359 changed silc_command_encode_payload_va to accept extra
8360 argument on variable argument list. The argument type must
8361 now be provided to the function. Also, added new function:
8362 silc_command_encode_reply_payload_va which is same as
8363 normal command_encode_payload_va except command status type
8364 is provided as extra argument.
8366 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8368 * Added ~./silc directory handling. The directory includes the
8369 public and private keys for the client.
8371 Added silc_client_check_silc_dir, silc_client_create_identifier
8372 and silc_client_load_keys.
8374 * Implemented SILC protocol compliant public key. Added public
8375 and private key saving to and loading from files.
8377 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
8378 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
8379 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
8380 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
8381 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
8383 Implemented: silc_pkcs_save_[public/private]_key[_data] and
8384 silc_pkcs_load_[public/private]_key.
8386 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8388 * Added silc_server_get_route (route.[ch]) to get connection
8389 data for the fastest route for given ID.
8391 * Implemented INVITE command on client and server. The command
8392 were re-defined in the SILC Protocol Specification and the
8393 implementation now complies with the specification.
8395 * Implemented PING command on client and server.
8397 * Implemented NAMES command on client and server. The server side
8398 supports currently only normal server not router server yet.
8399 Some changes to NAMES definition in SILC protocol specification.
8401 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8403 * Implemented LEAVE command on client and server.
8405 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
8406 again. This change was made to the protocol as well. Server
8407 should not violate the protocol specification anymore.
8409 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8411 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
8412 was tested. SOCKS4 was not but should work anyway.
