507 Added new options m and M to CMODE command in Irssi SILC
508 client to set these modes.
510 * Deprecated all administrative commands from SILC protocol
511 since they are highly implementation specific commands.
512 Updated protocol specs. Moved the old commands in
513 implementations to private range of command types. Affected
514 files are silcd/command.c, lib/silcclient/command.c and
515 lib/silcclient/command_reply.c. Protocol TODO #8.
517 * Fixed a bug in server where sending unknown command crashes
518 the server. Affected file silcd/command.c.
520 Wed Apr 3 09:57:47 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
522 * Added SILC_PROTOCOLVERSION macro to check protocol version
523 of a socket connection. The affected file is
524 lib/silcutil/silcsockconn.h.
526 * Added better error logging in rekey protocol. Affected file
529 * Do not check public key types in SKE during rekey. Affected
530 file lib/silcske/payload.c.
532 * Fixed the rekey protocol with PFS, which was totally broken.
533 Affected file silcd/protocol.c.
535 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
537 * Some client implementations quit network by doing first LEAVE
538 and then immediately SIGNOFF (like Bombyx). We now do check
539 after a short time after LEAVE notify and check whether the
540 client is still valid after LEAVE, and if not we remove it from
541 cache. Affected file is lib/silcclient/client_notify.c.
543 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
545 * Merged version 1.1.4 of zlib. Even if it not currently in use,
546 it's good not to have security holes here.
548 * Fixed a negative refcount situtuation for the config context.
549 Affected file is silcd/serverconfig.c.
551 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
553 * ROBOdoc documented lib/silcutil/silcutil.h.
555 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
557 * Optimized even more the SilcPacketContext structure. Now
558 totally saved 16 bytes of memory per context after optimization.
559 Affected files are lib/silccore/silcpacket.[ch].
561 * Made strict checks for valid SILC IDs. Affected file is
562 lib/silccore/silcid.c.
564 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
566 * Changed the object argument for silc_cipher_register,
567 silc_hash_register, silc_hmac_register and silc_pkcs_register
568 to const. Affected files are lib/silccrypt/silccipher.[ch],
569 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
571 * Changed the silc_get_username and silc_get_real_name to
572 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
574 * Fixed the Irssi SILC Client to use the silc_get_username and
575 silc_get_real_name insted of glib routines since the glib
576 routines only corrupt stack. Fixes the Irssi SILC to work in
577 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
579 * Fixed the Irssi to not use g_get_home_dir since it crashes
580 or returns garbage on cygwin and corrupts stack. Added function
581 get_home_dir to Irssi routines. Affected files are
582 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
584 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
586 * Made some structure optimizations. SFTP memory FS MemFSEntry
587 entry structure. Optimized SilcTask structure. Optimized
588 SilcPacketContext structure.
590 Affected files lib/silcsftp/sftp_fs_memory.c,
591 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
593 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
595 * And yet again reverted back the config thing since Johnny
596 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
599 * Fixed memory leaks from config object. Affected files are
600 silcd/serverconfig.[ch].
602 * Added support for adding new connections to the server in rehash.
603 After rehash they take effect.
605 Added support for changing the maximum allowed connections in
606 rehash. The number can grow but going smaller is not supported.
608 Added function silc_server_num_sockets_by_remote to the
609 silcd/server_util.[ch].
611 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
613 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
615 * Added preliminary checking during config parsing for a valid
616 public/private key and removed further checks in the code.
617 Affected files are silcd/serverconfig.[ch], server.c.
619 * Moved functions silc_server_drop() and silc_server_daemonise()
620 from server.c to silcd.c since they are stricly related to
621 the application activity.
623 * Reverted a small part of the automatic ref/unref since
624 it caused a double unref in some situations. Affected
625 files are silcd/silcd.[ch], server.c, serverconfig.c.
627 * Added some .cvsignore files in the lib directory.
629 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
631 * Fixed silc_net_gethostbyaddr to correctly resolve by
632 address. Affected file lib/silcutil/silcnet.c.
634 * Fixed the notify relaying to client. The HMAC to be used
635 with relayed packets ws wrong and caused decryption failure
636 at the client end. Affected file is silcd/packet_receive.c.
638 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
640 * Created new branch silc_protocol_1_0_branch.
642 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
644 * Changed the silc_server_config_* routines to be SilcServer
645 independent. They are now officially application specific code
646 and not part of generic server implementation. Affected files
647 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
649 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
651 * Added automatic referencing of config context in the
652 silc_server_config_alloc, and automatic unreferencing in the
653 silc_server_config_destroy. Affected files are
654 silcd/serverconfig.[ch], silcd/silcd.c.
656 * Fixed the silc_log_quick handling in the logging routines.
657 It didn't log quickly when it was TRUE. Affected file is
658 lib/silcutil/silclog.c. Also the flush delay was set even
659 if it was 0 in config file. Affected file is
660 silcd/serverconfig.c.
662 * Added support for changing key pair of the server in rehash.
663 Affected file silcd/server.c.
665 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
667 * Fixed the TOPIC_SET notify to not cras. It changed the topic
668 too early, before getting the channel entry. Affected file
669 is silcd/packet_receive.c.
671 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
673 * Added functions silc_server_config_[ref/unref], these are used
674 to prevent that the config object is destroyed.
676 No longer directly affect global variables silc_log_quick and
677 silc_log_delay, they are first cached inside the config object
678 and then applied with silc_server_config_setlogfiles().
680 silc_server_config_set_defaults() is now internal to
681 serverconfig.c, there are no reasons to show this internal stuff
684 Affected files are silcd/serverconfig.[ch].
686 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
687 fprintf's to stderr, since some code may be executed again after
688 the server went into the background. Affected files are
691 * Added rehash support. Added function silc_server_rehash() that
692 will perform all the basic tasks of the rehashing procedure.
694 * Added command line option `-x, --hexdump'. This will enable the
695 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
696 The option `--hexdump' implies `--debug'.
698 * Fixed a bad bug in the logging APIs (silcutil library) where
699 the application would crash after calling silc_log_reset_all().
701 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
703 * Fixed the KICKED notify handling in client library to
704 correctly remove the channel and all entries from the
705 channel when I was kicked. This bug crashed the client.
707 Fixed yet another but in KICKED notify handling to remove
708 the kicked client correctly from the channel.
710 Affected file is lib/silcclient/client_notify.c.
712 * Fixed a minor bug in looking up correct client entry
713 in KICKED notify in server. Affected file is
714 silcd/packet_receive.c.
716 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
717 sources correctly to distribution. Fixes --with-gmp option.
719 * Removed the manual rehashing from ID Cache, and changed it
720 to use the SILC Hash Table's auto rehash feature. Affected
721 file is lib/silccore/silcidcache.c.
723 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
725 * Fixed a bug in the silc_client_nickname_format function that
726 handles the multiple same nickname formatting. Two clients
727 with same nickname caused problems after the first one left
728 and rejoined. It didn't format the nickname correctly.
729 Affected file is lib/silcclient/idlist.c.
731 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
733 * Don't change the topic if olod topic is same as new one.
734 Affected file is silcd/packet_receive.c.
736 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
738 * Added cross-reference support to the SILC Documentation
739 generator. All types across all HTML files are now cross-
740 referenced. Affected files util/robodoc/generator.c and
741 scripts/silcdoc/silcdoc.
743 * Added file lib/silcutil/silctypes.h to include all the
744 arithmetic type definitions and some macros. Removed
745 includes/bitmove.h and moved macros to silctypes.h.
747 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
749 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
751 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
753 * Added `type' argument to silc_id_payload_parse_id function which
754 now returns the type of the ID to the sent pointer. Affected
755 file is lib/silccore/silcid.[ch].
757 * Added check for CMODE_CHANGE notify type that mode change is
758 allowed by the sender. Affected file silcd/packet_receive.c.
760 * Added check for CUMODE_CHANGE notify type that mode change is
761 allowed by the sender. Affected file silcd/packet_receive.c.
762 Added the ID type as CUMODE_CHANGE notify type as argument
763 to the `notify' client operation. Affected files are
764 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
766 * Added function silc_client_add_server to the client library.
767 Added support for resolving also channel and server info when
768 received unknown entity in notify packet. Affected files are
769 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
771 * Added function silc_command_get_status to return the command
772 status from the command reply's argument payload. Affected files
773 are lib/silccore/silccommand.[ch].
775 * Added check for KICKED notify type that the kicking is
776 allowed by the client. Affected file silcd/packet_receive.c.
778 * Created function silc_get_input which can be used to get input
779 (echo on or off) from user on command line. Affected files are
780 lib/silcutil/silcutil.[ch].
782 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
784 * Optimized silc_server_packet_relay_to_channel function.
785 Added new function silc_channel_message_payload_encrypt which
786 can be called directly if channel message payload needs to
787 be encrypted and is already encoded (no need to call _encode
788 function). Packet relaying is now done by router without any
789 extra memory allocations. Affected files are
790 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
793 * Fixed the INVITE notify handling. It took wrong arguments
794 as invite list and invite delete. Affected file is
795 silcd/packet_receive.c.
797 * Added check for TOPIC_SET notify type that the topic change is
798 allowed by the client. Affected file silcd/packet_receive.c.
800 * Added check for INVITE notify type that inviting is allowed by
801 the client. Affected file silcd/packet_receive.c.
803 * Changed the silc_server_client_on_channel to return the
804 SilcChannelClientEntry as well. Moved the function
805 silc_server_check_cmode_rights to server_util.[ch].
806 Affected files are silcd/server_util.[ch], silcd/command.c.
808 * Added function silc_server_check_umode_rights to check whether
809 changing client's user mode is allowed. Added check for
810 UMODE_CHANGE notify type that the umode change is allowed
811 by the client. Affected files are silcd/server_util.[ch],
812 silcd/packet_receive.c and silcd/command.c.
814 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
816 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
817 ID length. It ignored that ID can be IPv6 based as well.
818 Affected file lib/silccore/silcpacket.h.
820 * Fixed the silc_id_id2str and silc_id_str2id to take the
821 IPv6 address offset's into consideration. Affecte file is
822 lib/silccore/silcid.c.
824 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
826 * Fixed the internal Unix scheduler functions to check for
827 NULL context they may receive. The affected file is
828 lib/silcutil/unix/silcunixschedule.c.
830 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
832 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
833 can specify different directory with --home command line
834 parameter. Affected files irssi/src/silc/core/client_ops.c,
837 * SILC-specific commands aren't now executed if the active server
838 isn't of SILC-type, so there won't be problems with having
839 IRC and SILC protocol support in same client. Affected files
840 irssi/src/silc/core/silc-channels.c, silc-servers.c,
843 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
845 * Improved the signal support in SILC Schedule. Added new
846 function silc_schedule_signal_call which is used by application
847 to mark a signal to be called. It is now safe to perform
848 any kind of tasks in signal callbacks since it is guaranteed
849 that the application specified signal callback is called
850 after the signal is over. Affected files are
851 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
853 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
855 * Added `name' field to SilcChannelPrivateKey to represent
856 application given name for the key. Moved also the context from
857 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
858 Added the `name' argument also to the function
859 silc_client_add_channel_private_key.
861 Added function silc_client_current_channel_private_key to set the
862 current channel private key in use.
864 Added "change" command to KEY command which can be used to change
865 the current channel private key. Bound the command also to
868 Also affected files lib/silcclient/client_channel.c,
869 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
871 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
873 * Added silc_rng_get_byte_fast function in to the
874 lib/silccrypt/silcrng.[ch].
876 * Changed the interface of silc_packet_assemble and the
877 silc_packet_send_prepare. If silc_packet_assmble is now
878 called the application does not call silc_packet_send_prepare
879 because the library will call it automatically. These
880 interfaces now also return a reference to the outgoing buffer
881 which includes the assembled packet, which the application can
882 use to encrypt the packet.
884 Affected files are lib/silccore/silcpacket.[ch],
885 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
886 silcd/packet_send.c, server_backup.c and packet_receive.c.
888 * Fixed a packet sending bug on very high load, where outgoing
889 packet queue wasn't handled correctly and packets got corrupted.
890 Affected files are lib/silcutil/*/silc*sockconn.c,
891 lib/silcclient/client.c and silcd/server.c.
893 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
895 * Added macro SILC_PACKET_DATALEN which can be used during
896 packet assembling to check whether the data to be added to
897 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
898 len is truncated until it fits it.
900 Added checks for maximum length of channel message payload and
901 private message payload also.
903 Added checks for maximum packet length in server and in
906 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
907 lib/silcclient/client.c, lib/silccore/silcchannel.c and
908 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
909 lib/silcclient/client_prvmsg.c.
911 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
913 * Added silc_server_packet_queue_purge call to the
914 silc_server_disconnect_remote to assure that all data in the
915 queue before disconnecting is sent to the network. Affected
918 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
920 * Added the deleting of server's own ID cache entry to the
921 silc_server_free function. Free also everything else that
922 has been allocated in silc_server_init. The affected file
925 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
927 * Added functions silc_parse_version_string, silc_version_to_num,
928 and silc_ske_parse_version to parse SILC protocol style version
929 strings. Affected files lib/silcutil/silcutil.[ch] and
930 lib/silcske/silcske.[ch].
932 * Added new configuration params: version_protocol, version_software
933 and version_software_vendor to specify what version the remote
934 host must at least be to be able to connect to server. The vendor
935 string can be regex matched too. Added new function
936 silc_server_connection_allowed to check maximum number of allowed
937 connections, and allowed versions for incoming connections.
938 Affected files are silcd/server.c, server_util.[ch] and
941 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
943 * Added preliminary support for signals in scheduler. The
944 signals we care about are now blocked always when the scheduler
945 is locked. This way we can synchronise the use of signal with
946 scheduler. It is guaranteed that when signal occurs the scheduler
947 is not locked, and thus new tasks can be safely added to the
950 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
951 to silc_schedule_internal_init and silc_schedule_internal_uninit.
952 Added new platform specific routines
953 silc_schedule_internal_signals_[un]block and
954 silc_schedule_internal_signal_[un]register.
956 Added new functions to SILC Schedule API:
957 silc_schedule_signal_[un]register. Each signal that application
958 is going to use should be registered to the scheduler.
960 Affected files are lib/silcutil/silcschedule.[ch],
961 lib/silcutil/*/silc*schedule.c.
963 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
965 * Check for unauthenticated client and server in the
966 silc_server_new_client and silc_server_new_server functions.
967 Affected file silcd/packet_receive.c.
969 * Added function silc_string_is_ascii to check whether given
970 string is 7-bit ASCII string. Affected files are
971 lib/silcutil/silcutil.[ch].
973 * Added function silc_id_is_valid_server_id into the
974 silcd/serverid.c and added checking for valid Server ID's in
975 silc_server_new_server. The Server ID must always be based
976 on the server's public IP address.
978 * Added logging of DISCONNECT packet message in the server.
979 Affected file silcd/server.c.
981 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
983 * Changed all library interfaces that use Global RNG to also
984 accept SilcRng as argument. Affected files are
985 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
986 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
987 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
988 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
991 * Added function silc_pkcs_generate_key to the
992 lib/silccrypt/silcpkcs.[ch] for applications so that they
993 don't need to do pkcs->pkcs->init calls anymore.
995 * Remove SilcSocketConnection from the SFTP API since it really
996 wasn't needed there. The application has the information
997 saved in its contexts anyway and the SFTP layer doesn't need
998 know about it. Affected files lib/silcsft/silcsftp.h and
999 lib/silcsftp/sftp_[server/client].c.
1001 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
1002 The SilcSimContext is not SilcSim.
1004 * Fixed possible buffer overflows in silc_id_render in the
1005 lib/silcutil/silcutil.c.
1007 * On EPOC the global crypto module lists are not used at all
1008 in the crypto library. Added support for using the constant
1009 algorithm list on EPOC. Affected files are
1010 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
1013 * Fixed the handling of third parameter of KICKED notify, since
1014 it was mistakenly updated to SILC Protocol 1.0 even though it
1015 is to be included in 1.1. Since it is not in 1.0 it is not
1016 mandatory, and this fix now handles it only if it is provided,
1017 and it is not error if it is not provided. Affected file
1018 lib/silcclient/client_notify.c.
1020 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1022 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
1023 client. Affected file irssi/src/silc/core/client_ops.c.
1025 * Merged with Irssi 0.8.4 from irssi.org CVS.
1027 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1029 * Check for valid socket connection in client entries before
1030 sending any messages. Fixes a crash, but doesn't fix some

1057 file lib/silcutil/silcutil.[ch].
1059 * Added support for specifying multiple public keys for Client
1060 connection section in server configuration file. This makes it
1061 possible to accept multiple public keys from same host, or to
1062 make a section that accepts any incoming host, and have the
1063 accepted public keys listed in the section.
1065 Added functions silc_sever_[find/get]_public_key, added the
1066 support for this actually to all connection sections but only

1178 old name went against naming convention. Applications now
1179 include "silcclient.h" instead of "clientlibincludes.h".
1180 Removed includes/clientlibincludes.h, it is redundant now.
1182 * Renamed includes/version.h to silcversion.h.
1184 * Added really preliminary support for OS/2 into the util
1185 library. Only thread & mutex API is implemented, others
1186 are still to be implemented. Created the lib/silcutil/os2/

1220 * Added `user_count' to the SilcChannelEntry which now tells the
1221 number of users on the channel. The user count is now saved
1222 in normal server of global channels as well. Affected files
1223 silcd/server.c, idlist.h, packet_receive.c and command.c.
1225 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
1226 include file utility functions.

1241 * ROBOdoc documented the lib/silcske/silcske.h, and improved
1242 the SKE interface a bit.
1244 * Fixed padding problem in PKCS#1. The padding was not actually
1245 random since the random number generator was used incorrectly.
1246 This security bug affects only when encrypting with PKCS#1, and
1247 it is not currently used at all in SILC. SILC only use signing
1248 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.

1311 Affected files irssi/src/silc/core/silc-core.c,
1312 irssi/src/fe-text/silc.c.
1314 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1316 * Added new configuration options and blocks:
1317 keepalive_secs, reconnect_count, reconnect_interval,
1318 reconnect_interval_max, reconnect_keep_trying and
1319 require_reverser_lookup. Added ConnectionParam block, and
1320 implemented the connection parameters when connecting as
1321 initiator and when accepting connections as responder.

1333 the connection configuration object from the SilcServerConnection
1334 object instead of finding it during the connecting phase.
1335 Added the configuration object to SilcServerConnection struct.
1336 Affected files silcd/server_internal.h, server.c.
1338 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1340 * Add the client on channel after it was resolved at the
1341 channel message receiving, and it was not already on the
1342 channel. Affected file lib/silcclient/client_channel.c.
1344 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1360 authentication to be set at the same time.
1362 Added `prefer_passphrase_auth' setting in config file which
1363 can be used to set to prefer passwd auth if both passwd and
1364 public key is set. If not set, public key is preferred.
1365 This has effect only when being initiator (responder will try
1368 Added support for authentication with passphrase and public key
1369 at the same time. The passphrase is tried first always since
1370 it is faster to check.
1372 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
1374 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

1420 * Fixed the file transfer's key agreement payload to include
1421 zero port also if the hostname is NULL because it could not
1424 Call file transfer monitor callback now also if error occurs
1425 during key agreement protocol.
1427 Changed the silc_client_file_send interface to return the
1428 SilcClientFileError instead of session id. The session ID
1429 is returned into pointer provided as argument.

1446 file lib/silcutil/silclog.c.
1448 * Fixed the channel message payload decryption in the function
1449 silc_channel_message_payload_decrypt to not modify the original
1450 buffer before it is verified that the message decrypted
1451 correctly. Otherwise, next time it is called with correct
1452 channel key it won't encrypt since the payload is corrupted.
1453 Affected file lib/silccore/silcchannel.c.
1455 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1468 the table with foreach callback. The current entry may
1469 become invalid in the callback but it was referenced after
1470 the callback returned.
1472 Do not allow auto rehashing of hash table during the
1473 silc_hash_table_foreach operation, for same reasons as it is
1474 not allowed for SilcHashTableList. Affected files are
1475 lib/silcutil/silchashtable.[ch].
1477 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>

1501 * Fixed a bug in hash table tarversing. While the hash table
1502 is traversed with SilcHashTableList the table must not be
1503 rehashed. It is now guaranteed that auto rehashable tables
1504 are not rehashed while tarversing the list. Also defined that
1505 silc_hash_table_rehash must not be called while tarversing
1506 the table. Added function silc_hash_table_list_reset that must
1507 be called after the tarversing is over. The affected files are
1508 lib/silcutil/silchashtable.[ch].
1510 * Changed all hash table traversing to call the new
1511 silc_hash_table_list_reset in server and in client library.
1513 * Added function silc_client_on_channel to return the
1514 SilcChannelUser entry if the specified client entry is joined
1515 on the specified channel. This is exported to application as
1516 well. Affected files lib/silcclient/client_channel.c, silcapi.h.

1524 * Fixed the WHOWAS command's reply sending to support the
1525 lists correctly. Affected file silcd/command.c.
1527 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1529 * When sending JOIN command to router for processing the
1530 sender's old command identifier was not saved back to the
1531 sender's command context, fixed now. The affected file is
1534 * Create the key in JOIN command of the router did not return
1535 the channel key, added check for this. Affected file is
1538 * Fixed a channel ID update bug in JOIN command reply. Do
1539 not directly upgrade the ID but call the function
1540 silc_idlist_replace_channel_id if the ID was changed.
1541 Affected file silcd/command_reply.c.
1543 * Fixed memory leaks from command calling if it would fail.
1544 Affected file silcd/command.c.

1551 new silclist.h and silcdlist.h, all extern inline changed to
1554 * Removed dotconf from lib/dotconf, not needed anymore.
1556 * Removed TRQ from lib/trq, not needed anymore.
1558 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
1559 with server connections. Later this will be configurable
1560 in config file after new config file is done. Affected file
1563 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1565 * Fixed a crash in server related to channel announcements.
1566 Affected file silcd/server.c.
1568 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1570 * Fixed memory leaks in silc_server_create_new_channel*
1571 functions. Affected file silcd/server.c.
1573 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
1574 which ID was changed. This way the router will send the
1575 user list for the channel again, and server won't be in
1576 desync in some rare circumstances. Affected file is
1577 silcd/packet_receive.c.
1579 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1581 * Check for NULL socket pointer in the function
1582 silc_server_packet_send_to_channel_real. Affected file
1583 silcd/packet_send.c.
1585 * Fixed the BAN notify handling to correctly remove ban
1586 list. Affected file silcd/packet_receive.c.
1588 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1590 * Fixed some header addition to Toolkit distribution in
1591 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
1593 * Added lib/silcclient/client_ops_example.h as an template
1594 file for application programmers to quickly start using
1595 the SilcClientOperation functions in their application.
1596 Updated the lib/silcclient/README as well to tell about this
1597 nice file made available.
1599 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1601 * Call silc_server_remove_from_channels when removing client
1602 entry when NO_SUCH_CLIENT_ID was received. Affected file
1603 is silcd/command_reply.c.
1605 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1607 * Added server & router operator statistics updating. Affected
1608 file silcd/packet_receive.c and silcd/command.c.
1610 * Fixed the SERVER_SIGNOFF notify handling on normal server
1611 not to save the history information for clients. Same was
1612 fixed earlier in remove_clients_by_server function, but not
1613 here. Affected file silcd/packet_receive.c.
1615 * Raised the default connection-retry count from 4 to 7 in
1616 server. Affected file silcd/server.h.
1618 * Cancel any possible reconnect timeouts when we start the
1619 key exchange. Affected file silcd/server.c.
1621 * Do not reconnect on connection failure when SCONNECT was
1622 given. Affected files silcd/server.[ch].
1624 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1626 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
1628 * Fixed the NICK command to always give the unformatted
1629 nickname to the one giving the NICK command. If unformatted
1630 nickname is cached already it will be formatted and the
1631 local entry will always get the unformatted nickname.
1632 Affected file lib/silcclient/idlist.c.
1634 * Fixed some double frees from client library commands.
1635 Affected file is lib/silcclient/command.c.
1637 * Fixed CUMODE command in server to assure that no one can
1638 change founder's mode than the founder itself, there was a
1639 little bug. Affected file silcd/command.c.
1641 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1643 * Removed the SilcClientCommandDestructor from the client
1644 libary, it is not needed anymore. Affected files are
1645 lib/silcclient/silcapi.h, command[_reply].[ch],
1646 client_notify, idlist.c.
1648 * Fixed GETKEY command to first resolve client, and then
1649 resolve the server only if the client was not found, instead
1650 of resolving both at the same time. Affected file is
1651 lib/silcclient/command.c.
1653 * Added silc_client_start_key_exchange_cb and lookup the
1654 remote hostname and IP address before starting the key
1655 exchange with server. The affected file is
1656 lib/silcclient/client.c.
1658 * The server's public key is now saved using the IP address
1659 of the server and not the servername for the filename.
1660 The hostname public key filename is checked as an fall back
1661 method if the IP address based filename is not found.
1663 Fixed the GETKEY command to save the fetched server key
1664 in correct filename.
1666 Print the remote server's hostname now when new key is
1667 received during connection process. Affected file is
1668 irssi/src/silc/core/client_ops.c.
1670 * Return always our own public key to the client if it asks
1671 for it with GETKEY command. Affected file silcd/command.c.
1673 * Removed the use_auto_addr variable from default config
1674 file since it was in wrong section. Affected file is
1677 * Fixed TOPIC_CHANGE notification to not route it when it
1678 was sent using silc_server_send_notify_to_channel function.
1679 Affected file silcd/command.c.
1681 * Fixed silc_server_send_notify_kicked to send the kicker's
1682 Client ID also, it was missing. Affected files are
1683 silcd/command.c, silcd/packet_send.[ch].
1685 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1687 * Do not save client history information in SERVER_SIGNOFF.
1688 Fixes the bug in normal server that it does not detect
1689 the client becoming valid after the server becomes back
1690 online. Affected file silcd/server_util.c.
1692 * Added `sock_error' field into the SilcSocketConnection
1693 context. When error occurs during socket operation (read
1694 or write) the error is saved. Added also new function
1695 silc_socket_get_error to return human readable socket error
1696 message. Affected files are lib/silcutil/silcsockconn.[ch],
1697 lib/silcutil/unix/silcunixsockconn.c, and
1698 lib/silcutil/win32/silcwin32sockconn.c.
1700 * The server now prints the socket error message in the
1701 signoff for client. Affected file silcd/server.c.
1703 * Fixed the `created' channel information sending from router
1704 to server in JOIN command. Checks now whether the channel
1705 really was created or not and set it according that.
1707 Fixed the JOIN command to use the client entry's current
1708 ID during the joining procedure instead of the one it sent
1709 in the command (it is checked though), since it can change
1710 between the packet processing and command processing, and
1711 would just case unnecessary pain in the client end. Affected
1712 file silcd/command.c.
1714 * Fixed a channel key payload sending to use correct channel
1715 ID when the server was forced to change the channel's ID by
1716 router. Router sent the key payload with the old Channel ID.
1717 Affected file silcd/packet_receive.c.
1719 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1721 * Call silc_server_save_channel_key only if the key payload
1722 was provided in the JOIN command's command reply. Affected
1723 file silcd/command_reply.c.
1725 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1727 * Fixed silc_mp_sizeinbase to return the value correctly with
1728 MPI. Affected file lib/silcmath/mp_mpi.c.
1730 * Fixed the stop_server signal to correctly stop the scheduler
1731 and gracefully stop the server when SIGTERM or SIGINT signals
1732 are received. Affected file silcd/silcd.c.
1734 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1736 * Simple handling of TERM and HUP signals. Also added some log
1737 flushing call around. Affected file is
1740 * Fixed small bugs in silclog.c. Now buffering output will take
1741 effect after 10 seconds since startup: This will ensure that
1742 no important startup messages are lost. Also output redirection
1743 will preserve original format ([Date] [Type] message).
1744 Affected file is lib/silcutil/silclog.c.
1746 * Added two options to the config file, in the logging section:
1747 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1748 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1750 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1752 * Do not print the warning about log files not being initialized
1753 more than once to avoid excess logging. Affected file is
1754 lib/silcutil/silclog.c.
1756 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1757 the SIM copying in make install in Makefile.am.pre.
1759 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1761 * Rewritten silclog APIs. Globally interesting changes follows:
1762 silc_log_set_files() changed to silc_log_set_file().
1763 silc_log_set_callbacks() changed to silc_log_set_callback().
1764 ROBOdoc documented silclog header file.
1765 SilcLogCb now returns bool to wether inihibit the default
1766 handler or not (to keep the old behaviour return always TRUE).
1767 The new APIs should also fix the problem of the
1768 silcd_error.log file that was written in the current directory.
1771 Log files streams will remain opened after silc_log_set_file()
1772 call, means less CPU usage notably on high traffic servers.
1773 File streams are now full buffered, and flushed to the disk
1774 every 5 minutes, lesses HD activity and CPU usage.
1775 Messages can be redirected, allowing admins to configure
1776 one single logfile for all server messages.
1777 the silc_log_quick global variable to activate fast-logging.
1778 Affected files lib/silcutil/silclog.[ch]
1780 * Changed some code to conform new silclog APIs. Affected
1781 files are doc/example_silcd.conf.in, silcd/server.c
1782 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1785 * Fixed a memory leak that could occur in some situations.
1786 Affected file silcd/serverconfig.c.
1788 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1790 * Added the silc_client_del_client to remove the client from
1791 all channels as well. Affected file lib/silcclient/idlist.c.
1793 * Fixed the client library to correctly remove the client
1794 from all channels when the client entry is being destroyed.
1795 Affected file lib/silcclient/client_notify.c, command.c.
1797 * Added auto-nicking support to the client library. If the
1798 applicatio now sets client->nickname it will be sent to the
1799 server after connecting by the library. This way for example
1800 SILCNICK (or IRCNICK) environment variables will have effect
1801 and always change the nickname automatically to whatever
1802 it is wanted. Affected file lib/silcclient/client.[ch].
1804 * Renamed silc_server_command_bad_chars to the
1805 silc_server_name_bad_chars and moved it to the
1806 silcd/server_util.[ch]. Added also new function
1807 silc_server_name_modify_bad to return nickname that
1808 includes bad characters as new nickname without those
1809 bad characters. This check and modify is now used in
1810 silc_server_new_client when the username is initially set
1811 as nickname, so it must be checked to be valid nickname.
1812 Affected file silcd/packet_receive.c.
1814 * The nickname length is now taken from the packet for real
1815 and not trusted to strlen() since it clearly can return
1816 wrong length for nickname including bad characters. This
1817 also applies to channel names. Affected file silcd/command.c.
1819 * Removed the lib/silcsilm/modules directory. Modules are now
1820 compiled into the lib/silcsim. Fixed the copying of the
1821 modules to follow symbolic links in Makefile.am.pre.
1823 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1825 * Fixed silc_string_regexify list creation. Fixes bugs with
1826 BAN and INVITE commands in server. The affected file is
1827 lib/silcutil/unix/silcunixutil.c.
1829 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1831 * Removed the command destructor entirely from the server's
1832 command and command reply routines. It is not needed, and
1833 its usage was buggy and caused crashes. Affected files are
1834 silcd/command[_reply].[ch].
1836 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1838 * Cancel protocol and NULL sock->protocol if timeout
1839 occurred during protocol. Affected file silcd/server.c.
1841 * Cancel protocol timeouts always before calling the final
1842 callback, to assure that after final callback is called
1843 no other state will be called for the protocol anymore.
1844 Affected file silcd/protocol.c.
1846 * Print error log if incoming connection configuration could
1847 not be found. Affected file silcd/server.c.
1849 * Fixed JOIN command to correctly save the founder mode
1850 to the client on normal SILC server, when the channel
1851 was created by the router. Affected file silcd/command.c.
1853 * Fixed LIST command (hopefully) to send correct reply
1854 packets. Affected file silcd/command.c.
1856 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1858 * The silc_packet_receive_process now returns FALSE if the
1859 read data was invalid packet, and TRUE if it was ok.
1861 The server now checks that if unauthenticated connection
1862 sends data and its processing fails the server will close
1863 the connection since it could be a malicious flooder.
1865 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1867 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1869 * Make sure the warning about error opening a log file is
1870 printed only once and not everytime it fails (produces
1871 too much useless log). Affected file lib/silcutil/silclog.c.
1873 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1875 * Made the silc_server_daemonise() function more readable.
1876 Affected file silcd/server.c.
1878 * Pid file is now optional, the user may comment it out from
1879 the config file. Removed define SILC_SERVER_PID_FILE, we
1880 don't need a default any longer. Affected file
1881 configure.in.pre, lib/Makefile.am.pre.
1883 * Make some use of the pid file. The server now dies at startup
1884 if it detects a valid pid file on his path. The server would
1885 die anyway in this circumstance, because of the bind() failure.
1886 Affected file silcd/silcd.c.
1888 * No longer compiling lib/dotconf.
1890 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1892 * Fixed JOIN command parsing not to crash. Affected file
1893 lib/silcclient/command.c.
1895 * Fied the NICK_CHANGE notify to add the new client entry
1896 even it is resolved. This removes an <[unknown]> nick
1897 thingy bug in the client. Affected file is
1898 lib/silcclient/client_notify.c.
1900 * Do not try to allocate 0 bytes (efence does not like it)
1901 in lib/silccore/silccomand.c when encoding payload.
1903 * Do not take IRCNICK as nickname in Irssi SILC client since
1904 it is not possible to set nickname before hand connecting
1905 the server (TODO has an entry about adding auto-nicking
1908 * Changed the silc_server_command_pending to check whether
1909 there already exists an pending entry with the specified
1910 command, command identifier and pending callback. This is
1911 to fix IDENTIFY and WHOIS related crashes that may register
1912 multiple pending commands with same identifier. Affected
1913 file silcd/command.c.
1915 * Fixed the server to reconnect to the router even if it
1916 was already reconnecting and EOF was received. This to
1917 fix a possibility that the server wouldn't ever try to
1918 auto-reconnect to the router. Affected file silcd/server.c.
1920 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1922 * Fixed the server's password authentication to use the
1923 length of the locally saved password, and not the one
1924 sent in the packet. Affected file silcd/protocol.c.
1926 * Fixed same password authentication problem in the
1927 Authentication Payload handling routines in
1928 lib/silccore/silcauth.c.
1930 * Yet another password authentication problem fixed with
1931 channel password handling in silcd/command.c.
1933 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1935 * If first character of string in silc_parse_userfqdn is '@'
1936 then do not parse it. Affected file is
1937 lib/silcutil/silcutil.c.
1939 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1941 * Fixed minor bug in IDENTIFY command reply sending, which
1942 caused various weird problems during JOIN when it was
1943 resolving names for users. Affected file silcd/command.c.
1945 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1947 * Fixed the IDENTIFY command reply sending to chech better valid
1948 clients. It was possible to send incomplete list of replies.
1949 Affected file silcd/command.c.
1951 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1953 * Added silc_client_command[s]_[un]register functions now to
1954 dynamically register the commands in client library. Removed
1955 the static table of commands. This allows the client library
1956 to call commands without causing the application to know about
1957 what commands library has called.
1959 Removed the INFO command reply kludge to detect when the command
1960 was called by library. Now library use its own command reply
1961 function for INFO command.
1963 Added function silc_client_command_call to call a command.
1964 Application can use it to call command, not access the structure
1967 Now all commands that are sent by the client library (not
1968 explicitly sent by application) use own command reply functions.
1970 Affected files around lib/silcclient/ and in
1971 irssi/src/silc/core/.
1973 * Fixed the WHOIS command reply sending to chech better valid
1974 clients. It was possible to send incomplete list of replies.
1976 Fixed the WHOIS and IDENTIFY to send the request to router
1977 if normal server did not do it and did not find any results.
1979 Affected file silcd/command.c.
1981 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1983 * Moved the internal data from SilcClient context into its
1984 own file, not accesible to application. Affected files
1985 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1986 and other files in client library.
1988 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1990 * Added doc/examples installation target in Makefile.am.pre.
1993 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1995 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1996 commands the found client entry will be removed from the
1997 cache, after notifying application about the error. Affected
1998 file lib/silcclient/command_reply.c.
2000 * Changed the /MSG to check for exact nickname user gave, and
2001 not let `nick' match `nick@host' if it is only one found. Now,
2002 user must type the exact nickname (like nick@host2) even if
2003 there are no more than one same nicks found. This is to avoid
2004 a possibility of sending nickname to wrong nickname since
2005 `nick' could match `nick@host'. Affected file is
2006 irssi/src/core/silc-servers.c.
2008 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2010 * Do not print "you are now server operator" or similar when
2011 giving /away command. Affected files are
2012 irssi/src/silc/core/client_ops.c, silc-servers.h.
2014 * Made the silc_server_command_pending_error_check to send
2015 the same command reply payload it received back to the
2016 original sender of the command. This way all arguments
2017 that was received by the server will be received by the
2018 client too. Affected file silcd/command.c.
2020 * Added the silc_idcache_add to return the created cache entry
2021 to a pointer. Affected file lib/silccore/silcidcache.[ch].
2023 * Add global clients to expire if they are not on any channel.
2024 This is because normal server will never know if they signoff
2025 if they are not on any channel. The cache expiry will take
2026 case of these entries. This is done by normal servers only.
2027 The affected files are silcd/command_reply.c,
2028 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
2030 * If server receives invalid ID notification for WHOIS or
2031 IDENTIFY and the ID exists in the lists, it is removed.
2032 Affected file silcd/command_reply.c.
2034 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
2035 in client then client entry that it matches is searched and
2036 the nickname is printed on the screen for user. Affected
2037 file irssi/src/silc/core/client_ops.c.
2039 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2041 * Use cache entry expire time in the LIST command reply to
2042 purge old entries from the cache after the LIST command
2043 reply has been received. This way we don't have non-existent
2044 entries in the cache for too long. Affected file is
2045 silcd/command_reply.c.
2047 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2049 * If we are normal server, and we've not resolved client info
2050 in WHOIS or IDENTIFY from router, and it is global client,
2051 we'll check whether it is on some channel. If it is not
2052 then we cannot be sure about its validity and will resolve it
2053 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
2054 file silcd/command.c.
2056 * Search channel by name (if possible) rather than by ID
2057 in IDENTIFY command's command reply. Affected file is
2058 silcd/command_reply.c.
2060 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2062 * Distribute to the channel passphrase in CMODE_CHANGE notify.
2063 Updated specs and implemented it. Affected file silcd/command.c,
2064 silcd/packet_send.c and silcd/packet_receive.c.
2066 * Implemented the <founder auth> payload handling in the JOIN
2067 command. If provided all conditions for channel joining
2068 except requirement to provide correct passphrase can be
2069 overrided by the channel founder. Updated the protocol specs.
2070 Affected file silcd/command.c.
2072 Added support for founder auth in JOIN command in client
2073 library. Fixed the parsing of the JOIN command now to support
2074 all options as they should be. The affected file is
2075 lib/silcclient/command.c.
2077 * Optimized the WHOIS and IDENTIFY commands to send the request
2078 to router only if it includes nicknames or other names. If
2079 they include only IDs then check the local cache first before
2080 routing. Affected file is silcd/command.c.
2082 * Added channels topic announcements. Affected file is
2083 silcd/packet_receive.c and silcd/server.c.
2085 * Fixed the silc_server_send_notify_topic_set to really destine
2086 the packet to channel. Affected file silcd/packet_send.c.
2088 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
2089 library. Affected file lib/silcclient/client_notify.c.
2091 * Added UMODE announcements. Affected file silcd/server.c.

2108 * ROBOdoc documented the lib/silcske/groups.h file and a
2109 bit changed the interface for better.
2111 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2113 * Update the client entry context in the ID cache after
2114 nick change. Affected file lib/silcclient/command.c.
2115 Fixes the CUMODE command when regaining founder privileges,
2116 and a little WHOIS problem.
2118 * Fixed silc_net_gethostbyname to correctly call the
2119 inet_ntop. Affected file lib/silcutil/silcnet.c.
2121 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2123 * Added IPv6 support checking to the configure.in.pre, added
2124 also --enable-ipv6 option to override the check. Affected
2125 file configure.in.pre.
2127 * The silc_thread_create now calls the start function
2128 directly if threads support is not compiled in. Removes
2129 ugly #ifdef's from generic code. Affected files are
2130 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
2132 * Added silc_net_gethostby[name/addr]_async to asynchronously

2144 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
2145 routines. Added silc_net_is_ip[4/6]. Affected file is
2146 lib/silcutil/unix/silcunixnet.c. All routines that take
2147 address as argument now supports both IPv4 and IPv6 addresses.
2149 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2151 * Fixed LIST command reply sending in server. Affected file
2154 * Server now sends the kicker's client ID in the KICK notify
2155 to the kicked client. Affected file silcd/command.c.
2157 * The client library now parses the kickers client ID and
2158 UI displays it. Affected files lib/silcclient/client_notify.c
2159 and irssi/src/silc/core/silc-channels.c, module-formats.c.
2161 * Made all payload parsing function prototypes consistent.
2162 They all take now const unsigned char * and uint32 pair as
2163 the payload data instead of SilcBuffer. Changes all around
2164 the source tree. Other unsigned char* -> const unsigned char*
2165 changes around the tree as well.
2167 * Optimized SFTP client and server packet sending not to
2168 allocate new buffer for each packet but to recycle the
2169 first allocated buffer. Affected files are
2170 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
2172 * Optimized the SFTP client to use SilcList instead of
2173 SilcDList for requests, because it is faster. Affected file
2174 is lib/silcsftp/sftp_client.c.
2176 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
2177 into lib/silccore/silcid.[ch].
2179 Renamed silcpayload.[ch] into silcargument.[ch].
2181 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2183 * If client entry is deleted with active key agreement
2184 session, abort the session.
2186 The silc_client_abort_key_agreement now calls the completion
2187 callback with new SILC_KEY_AGREEMENT_ABORTED status.
2189 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
2192 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2194 * Don't use __restrict in older GCC's. Affected file is
2195 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
2197 * silc_net_localhost now attempts to reverse lookup the
2198 IP/hostname. Affected file lib/silcutil/silcnet.c.
2200 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
2201 command. It can be used to gain founder privileges at
2202 the same time when joining the channel.
2204 Defined that the SILC_NOTIFY_TYPE_KICKED send the
2205 kicker's client ID as well. Updated protocol specs.
2207 Defined that the server must send SILC_COMMAND_IDENTIFY
2208 command reply with error status to client who sent
2209 private message with invalid client ID.
2211 Updated the protocol specification.
2213 * Added silc_server_send_command_reply to send any
2214 command reply. Affected file silcd/packet_send.[ch].
2216 * Added silc_id_payload_encode_data to encode ID payload
2217 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
2219 * The server now send IDENTIFY command reply with error
2220 status if client ID in private message is invalid. Affected
2221 file silcd/packet_receive.c.
2223 * Save the server key file with server's IP address in
2224 the filename instead of hostname. The affected file is
2225 irssi/src/silc/core/client_ops.c.
2227 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2229 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
2232 * Added libtool support for compiling shared objects in
2233 lib/silcsim. Affected file configure.in.pre and
2234 lib/silcsim/Makefile.am. Original patch by cras.
2236 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2238 * Pid file configuration, and server's config file fixes
2239 patch by toma. Updated CREDITS file.
2241 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2243 * Fixed silc_client_channel_message to not try to decrypt
2244 the message twice if it resolved the destination client
2245 information. This could cause of dropping one channel
2246 message. Affected file lib/silcclient/client_channel.c.
2248 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2250 * Added silc_client_run_one into lib/silcclient/silcapi.h and
2251 lib/silcclient/client.c. This function is used when the SILC
2252 Client is run under some other scheduler, or event loop or
2253 main loop. On GUI applications, for example this may be
2254 desired to used to run the client under the GUI application's
2255 main loop. Typically the GUI application would register an
2256 idle task that calls this function multiple times in a second
2257 to quickly process the SILC specific data.
2259 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2261 * Fixed silc_server_drop() for dropping the supplementary
2262 groups as well, this could cause a security hole on some
2265 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2267 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
2270 * Write PID file after dropping privileges. Added -F option
2271 to run server on foreground. A patch by debolaz.
2272 Affected files silcd/server.c, silcd/silcd.c.
2274 * Fixed MOTD to return the MOTD file server name. Affected
2275 file silcd/command.c.
2277 * Added INFO command reply handling to the Irssi SILC Client.
2278 Affected file irssi/src/silc/core/client_ops.c.
2280 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2282 * Fixed the silc_idcache_list_* routines to really support
2283 the dynamic list. Fixes a crash. Affected file is
2284 lib/silccore/silcidcache.c.
2286 * Fixed the LIST command reply to really call LIST command's
2287 pending callbacks. Affected file silcd/command_reply.c.
2289 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2291 * Update conn->local_entry->nickname after giving NICK
2292 command. Affected file lib/silcclient/command.c.
2294 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
2296 * Added the [pid] option to the silcd configuration file
2298 Affected files: serverconfig.[ch] and silcd.c
2300 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2302 * Save fingerprint in WHOIS command reply in server.
2303 Affected file silcd/command_reply.c.
2305 * Fixed NICK commands pending callback registration.
2306 Affected file lib/silcclient/command.c.
2308 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2310 * Use ++server->cmd_ident when sending commands in server,
2311 instead of random number. Affected file silcd/command.c.
2313 * Fixed GETKEY command reply to call actually GETKEY pending
2314 command callbacks. Affected file silcd/command_reply.c.
2316 * A bit stricter check for nicknames. Check for same nickname
2317 in NICK command also. Affected file silcd/command.c.
2319 * Do not call INFO command everytime client ID changes, only
2320 during first connecting. Affected file lib/silcclient/client.c.
2322 * Set the new nickname only after successful command reply for
2323 NICK command is returned by server. Affected file
2324 lib/silcclient/command.c.
2326 * Remove nicknames from nicklist during server_signoff notify.
2327 Should fix /NAMES bit more. The affected file is
2328 irssi/src/silc/core/silc-channels.c.
2330 * Added `fingerprint' field to the SilcIDListData in the
2331 silcd/idlist.h to hold the fingerprint of the client's
2334 Send the fingerprint of the client's public key in WHOIS
2337 Affected files silcd/command.c, and silcd/idlist.[ch].
2339 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
2340 create fingerprint from given data.
2342 * Show the fingerprint of the client's public key in WHOIS.
2343 Affected files irssi/src/module-formats.[ch] and
2344 irssi/src/silc/core/client_ops.c.
2346 * Format the multiple same nicknames also during JOIN and
2347 NICK_CHANGE notifys. Affected file is
2348 lib/silcclient/client_notify.c.
2350 * Do not print error on screen for invalid private message
2351 payload since it can come if someone is sending private
2352 messages with wrong key. Affected file
2353 lib/silccore/silcprivate.c.
2355 * Fixed multiple concurrent /PING crash. Affected file
2356 lib/silcclient/command.c.
2358 * Changed the wrong ID encoding. All IP addresses must be
2359 in MSB first order in encoded format. They were encoded
2360 wrong and was in LSB format. Affected files are
2361 silcd/serverid.c, lib/silcutil/silcutil.c.
2363 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
2365 * Call the `connect' client operation through the scheduler
2366 in case of error. Affected file lib/silcclient/client.c.
2368 * Call the `failure' client operation even if the error
2369 occurred locally during a protocol. Affected file is
2370 lib/silcclient/protocol.c.
2372 * Added support of sending LIST command to router from normal
2373 server. This way normal server can get list of all channels
2374 in the network too. Fixed the channel list sending in the
2375 server too. Affected files are silcd/command.c, and
2376 silcd/command_reply.[ch].
2378 * Added silc_server_update_channels_by_server and
2379 silc_server_remove_channels_by_server. They are used during
2380 disconnection of primary router and in backup router protocol.
2381 Affected file silcd/server_util.[ch], silcd/server.c and
2382 silcd/server_backup.c.
2384 * Fixed channel adding to global list in IDENTIFY command
2385 reply in server. Affected file silcd/command_reply.c.
2387 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2389 * If the incoming packet type is REKEY or REKEY_DONE process
2390 that packet always synchronously. Fixes yet another MAC
2391 failed error on slow (dialup) connections. Affected file
2392 lib/silcclient/client.c and silcd/server.c.
2394 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2396 * Call check_version SKE callback for initiator too. Affected
2397 file lib/silcske/silcske.c.
2399 * Implemented fix for security hole found in the SKE that was
2400 fixed in the specification few days back; the initiator's
2401 public key is now added to the HASH value computation.
2402 Added backwards support for the old way of doing it too, for
2403 old clients and old servers. Affected file is
2404 lib/silcske/silcske.c.
2406 * Enabled mutual authentication by default in SKE. If initiator
2407 is not providing mutual authentication the responder will
2408 force it. This will provide the proof of posession of the
2409 private key for responder. The affected files are
2410 lib/silcclient/protocol.c and silcd/protocol.c.
2412 * Do not cache anymore the server's public key during SKE.
2413 We do mutual authentication so the proof of posession of
2414 private key is done, and if the server is authenticated in
2415 conn auth protocol with public key we must have the public
2416 key already. Affected file silcd/protocol.c.
2418 * Added new global debug variable: silc_debug_hexdump. If
2419 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
2420 file lib/silcutil/silclog.[ch].
2422 * Fixed compilation warning due to char * -> const char *.
2423 Affected files lib/silcutil/silcnet.h, and
2424 lib/silccore/silcauth.[ch].
2426 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2428 * Fixed CMODE command when new channel key was created. If
2429 the creation failed the old key was removed. Next time giving
2430 same command would crash the server since the old key was
2431 freed already. Affected file silcd/command.c.
2433 * Fixed the silc_server_announce_get_channels to not crash
2434 on reconnect. Affected file silcd/server.c.
2436 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2438 * Added silc_log_set_debug_string function to set a regex
2439 string to match for debug output. Only the function names,
2440 or filenames matching the given debug string is actually
2441 printed. This way it is possible to filter out those debug
2442 strings that user is not interested in.
2444 Fixed a bug in silc_string_regexify.
2446 Affected files lib/silcutil/silclog.[ch], and
2447 lib/silcutil/unix/silcunixutil.c.
2449 * Changed the -d options in both server and Irssi SILC client
2450 to take the debug string as argument. Affected files
2451 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
2453 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2455 * Added silc_hash_babbleprint to create a Bubble Babble
2456 Encoded fingerprint. The encoding is developed by Antti
2457 Huima (draft-huima-babble-01.txt), and it creates human
2458 readable strings out of binary data. Affected file
2459 lib/silccrypt/silchash.[ch].
2461 * Print the babble print now in addition of fingerprint as well
2462 in Irssi SILC client. Affected files are
2463 irssi/src/fe-common/silc/module-formats.[ch],
2464 irssi/src/fe-common/silc/core/client_ops.c.
2466 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2468 * Fixed a security problem found in SKE. The initiator's
2469 public key too is now added to the HASH hash value creation
2470 which is signed by the responder to create the SIGN value.
2471 This will prevent anyone in the middle to lie to the responder
2472 about the initiator's public key. If this is done now, the
2473 man in the middle will get caught. Updated the protocol
2476 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2478 * Better installation directory handling. Configure module
2479 paths and other paths automatically to example_silc* files
2480 in doc/. A patch by toma.
2482 * Fixed compiler warning from MPI library, and from SILC RNG.
2485 * Added SILC_SERVER_PID_FILE to define the pid file for server.
2486 It can be configured with ./configure. A patch by toma.
2488 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2490 * Find correct make to use in prepare-clean. A patch by
2491 toma. Affected file prepare-clean.
2493 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
2495 * Added irssi variables use_auto_addr, auto_bind_ip,
2496 auto_bind_port and auto_public_ip.
2498 * Changed the interface for silc_client_send_key_agreement
2499 in lib/silcclient/silcapi.h
2503 irssi/src/silc/core/silc-core.c
2505 lib/silcclient/silcapi.h
2506 irssi/src/silc/core/silc-channels.c
2507 lib/silcclient/client_keyagr.c
2510 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2512 * Added silc_pkcs_public_key_compare to compare two
2513 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
2515 * Check that the client who set the founder mode on the
2516 channel is the same client that is giving the founder
2517 mode to itself. It is done by comparing the saved public
2518 key (it is saved even in the authentication is passphrase).
2519 Affected file silcd/command.c.
2521 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2523 * Do not process packet for disconnected socket connection.
2524 Affected file lib/silccore/silcpacket.c.
2526 * Process the DISCONNECT packet through scheduler in the
2527 client library. Affected file lib/silcclient/client.c.
2529 * Fixed the silc_client_packet_parse to not to increase
2530 the packet sequence number if the conn->sock and the
2531 current socket connection is not same. This can happen
2532 for example during key agreement when the conn includes
2533 multiple socket connections (listeners). Affected file
2534 lib/silcclient/client.c.
2536 * The sender of the file transfer request now provides also
2537 the pointer (listener) for the key exchange protocol. If
2538 the listener cannot be created then it sends empty key
2539 agreement and lets the receiver provide the listener.
2541 Added `local_ip' and `local_port' arguments to the
2542 silc_client_file_send. If they are provided they are used,
2543 if not then it will attempt to find local IP address, if
2544 not found or bind fails then the remote client will provide
2547 Affected files are lib/silcclient/client_ftp.c and
2548 lib/silcclient/silcapi.h.
2550 * Extended the FILE SEND command to support defining the
2551 local IP and port for key exchange listener. They are
2552 optional. Affected file irssi/src/silc/core/silc-servers.c.
2554 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2556 * Defined to WHOIS command reply the sending of fingerprint
2557 of the client's public key (if the proof of posession of the
2558 corresponding private key is verified by the server).
2559 Updated to the protocol specification.
2561 * Added support of receiving the client's public key's
2562 fingerprint in command reply in client library. Affected
2563 file is lib/silcclient/command_reply.c, and
2564 lib/silcclient/idlist.[ch].
2566 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2568 * Do not send over 128 chars long nickname to the server
2569 in NICK command. Affected file lib/silcclient/command.c.
2571 * Do not send over 256 chars long channel names to the server
2572 in JOIN command. Affected file lib/silcclient/command.c.
2574 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2576 * Assure that silc_server_close_connection cannot be called
2577 twice for same socket context. Affected file is
2580 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2582 * Send error message to application if opening file for
2583 writing during file transfer fails. Affected file is
2584 lib/silcclient/client_ftp.c.
2586 Remove all file transfer sessions for a client that we're
2587 removing from ID cache.
2589 Affected file is lib/silcclient/client_ftp.c.
2591 * Fixed silc_net_addr2bin to return correct address. Affected
2592 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2594 * Fixed file transfer session removing on signoff notify.
2595 Affected file irssi/src/silc/core/silc-servers.c.
2597 * Added the SilcClientFileError to be returned in the monitor
2598 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
2599 Affected file lib/silcclient/silcapi.h.
2601 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2603 * Fixed a crash in silc_client_ftp_free_sessions and
2604 silc_client_ftp_session_free_client. Affected file
2605 lib/silcclient/client_ftp.c.
2607 * Added `disabled' field in the SilcChannelEntry in the server
2608 to indicate if the server entry is disabled. Affected file
2609 silcd/idlist.h, silcd/command[_reply].c.
2611 * SILC server adds now /var/run/silcd.pid everytime it is
2612 started. Affected file silcd/silcd.c.
2614 * Added silc_server_packet_send_clients to send a packet to
2615 the provided table of client entries. Affected file
2616 silcd/packet_send.[ch].
2618 * Fixed a crash in client resolving in client_prvmsg.c in
2619 client library. Affected file lib/silcclient/client_prvmsg.c.
2621 * Do not actually remove the client directly from ID cache
2622 during SERVER_SIGNOFF, but invalidate it. This way we
2623 preserve the WHOWAS info for the client. Affected file
2624 silcd/server_util.c.
2626 * Fixed SERVER_SIGNOFF notify handling in the server. The
2627 server is now able to process incoming SERVER_SIGNOFF notify
2628 for a server that it doesn't even know about. It will remove
2629 the clients provided in the notify. Affected file
2630 silcd/packet_receive.c.
2632 * Check for partial packet in data queue after every packet that
2633 was found from the queue. Return and wait for more data if
2634 there is partial data in queue. Affected file is
2635 lib/silccore/silcpacket.c.
2637 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2639 * Added SilcClietFileError enum to indicate error in
2640 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT

2642 Affected files lib/silcclient/silcapi.h and
2643 lib/silcclient/client_ftp.c.
2645 * Check that newsize in silc_buffer_realloc is larger than
2646 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
2648 * Added better monitor of file transfers. It now monitors
2649 key agreement protocol during the file transfer too. Added
2650 error reporting too. Affected files
2651 irssi/src/silc/core/silc-servers.c,
2652 irssi/src/fe-common/silc/module-formats.[ch].
2654 * Wrote a help file for FILE command.
2656 * Added silc_rng_global_get_byte_fast to get not-so-secure
2657 random data as fast as possible. Random data is read from
2658 /dev/urandom if available and from the SILC RNG if not
2659 available. It is used in padding generation. Affected file
2660 lib/silccrypt/silcrng.[ch].
2662 * All packets in client library are now processed synchronously.
2663 Optimized packet processing a lot. Affected file
2664 lib/silcclient/client.c.
2666 * All server connection packets are processing synchronously
2667 now in server, to optimize packet processing. Affected file
2670 * Include files are installed now only in Toolkit distribution
2671 if make install is given. Affected files: all Makefile.am's.
2673 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2675 * Assure that silc_client_notify_by_server_resolve does not
2676 resolve the client information multiple times. If it cannot
2677 be found by the first it cannot be found at all. Affected
2678 file lib/silcclient/client_notify.c.
2680 * Fixed WHOWAS command reply calling. Affected file
2681 lib/silcclient/command_reply.c.
2683 * Removed all references to silc_idlist_get_client from the
2684 Irssi SILC client since that call is internal call used by
2685 the library. The Irssi SILC client will use now client
2686 retrieval functions found in silcapi.h.
2688 * Fixed a bug in resolving nickname info before sending
2689 private message. It used freed memory. Affected file
2690 irssi/src/silc/core/silc-servers.c.
2692 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2694 * Assure my_channels statistics cannot go negative in server.
2695 Affected files silcd/server.c, silcd/server_util.c.
2697 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

2711 * Added silc_net_localip to return local host's IP address.
2712 Affected file lib/silcutil/silcnet.[ch].
2714 * If key exchange or rekey protocol is active for a connection
2715 parse all packets syncronously since there might be packets
2716 in packet queue that we are not able to process without first
2717 processing packets before them. Affected file silcd/server,
2718 lib/silcclient/client.c.
2720 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2721 whether library should continue processing the packet.
2722 Affected file lib/silccore/silcpacket.h.
2724 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and

2753 lib/silcutil/silcutil.[ch].
2755 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2757 * Resolve the client info when received private message or
2758 channel message for a client which nickname we don't know.
2759 Affected files lib/silcclient/client_prvmsg.c and
2760 lib/silcclient/client_channel.c.
2762 * Do not crash in /KEY if client is not connected. Affected
2763 file irssi/src/silc/core/silc-channels.c.
2765 * Added SilcClientStatus field to the SilcClientEntry in the
2766 lib/silcclient/idlist.h.
2768 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
2769 is incomplete and is being resolved, it won't be resolved
2772 Make sure also that USERS command reply does not resolve
2773 twice information. Affected file is
2774 lib/silcclient/command_reply.c.
2776 Make sure that silc_client_get_clients_by_list does not
2777 resolve twice same information.
2779 * Check for valid client->id in the silc_server_free_client_data.
2780 Affected file silcd/server.c.
2782 * Fixed /GETKEY nick@server not to crash if the server entry
2783 is not found. Affected file lib/silcclient/command.c.
2785 * Fixed the silc_server_check_cmode_rights to check the
2786 requested modes correctly. Affected file silcd/command.c.
2788 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2790 * Better checks for non-printable chars in nick added.
2791 Affected file silcd/command.c.
2793 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2795 * Call the silc_server_udpate_servers_by_server in the
2796 primary router that comes back online in the backup resuming
2797 protocol. Otherwise it routes packets wrong. Affected file
2798 silcd/server_util.[ch], silcd/server_backup.c.
2800 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2802 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2803 lib/silcutil/silcbuffmt.[ch].
2805 * Redefined the SILC packet header to include the padding
2806 length. Affected file lib/silccore/silcpacket.[ch].
2808 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2809 length for maximum padding up to 128 bytes). Affected
2810 file lib/silccore/silcpacket.h.
2812 * Removed all backwards support for old 0.5.x MAC thingies.
2813 The SILC packet header change makes it impossible to be
2814 backwards compatible.
2816 * Send the ENDING packet with timeout in the backup resuming
2817 protocol. This is to assure that all routers has connected
2818 to the primary router. Affected file silcd/server_backup.c.
2820 * Changed the RNG to take the first IV from random data. It
2821 used to take it from zero actually. Changed the RNG also
2822 to use /dev/urandom during session. /dev/random is used
2823 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2825 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2827 * Changed the SILC packet header to have the first two bytes
2828 (the packet length) encrypted. Affected files aroung the
2829 code tree, lib/silccore/silcpacket.[ch]. Removed the
2830 SilcPacketCheckDecrypt callback. It is not needed anymore
2831 since the silc_packet_receive_process will determine now
2832 whether the packet is normal or special.
2834 * Implemented the unidirectional MAC keys. Affected files
2835 lib/silcske/silcske.c, silcd/protocol.c and
2836 lib/silcclient/protocol.c.
2838 * Implemented the packet sequence number to the MAC computation.
2839 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
2840 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
2841 lib/silcclient/protocol.c.
2843 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2845 * Allow backup router to announce servers. All servers
2846 announced by backup router are added to the global list
2847 automatically. Update hte server's socket to our primary
2848 router also when backup router announces a server.
2849 Affected file silcd/packet_receive.c.
2851 * Do not update the client->router in the function
2852 silc_server_udpate_clients_by_server if the client is on
2853 global list. We might fail to find any specific server
2854 for locally connected clients and local cell clients. They
2855 should still use the `from' and not `to' as client->router.
2856 This fixes backup router resuming protocol. Affected file
2857 silcd/server_util.c.
2859 * Decrease channel statistics count only if the channel
2860 deletion worked. Affected files are silcd/server.c and
2861 silcd/server_util.c.
2863 * Added silc_server_update_servers_by_server to update origin
2864 of all server entries. Used during backup router protocol.
2865 Affected files silcd/server_util.[ch], silcd/server.c. and
2866 silcd/backup_router.c.
2868 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
2869 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
2870 silc_hmac_get_hash and silc_hmac_get_name. Affected file
2871 lib/silccrypt/silchmac.c.
2873 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2875 * Assure that router cannot reroute the same channel message
2876 to the sender. Affected file silcd/packet_receive.c.
2878 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2880 * Made better checks that the channel message is not sent
2881 to the router it came from. Affected file is
2882 silcd/packet_send.c. Fixed memory leak too.
2884 * Announce informations for incoming router connection, but
2885 only after checking if it is replaced by backup router.
2886 Affected file silcd/packet_receive.c.
2888 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2890 * Fixed the backup resuming protocol to work in multiple
2891 router environment. Affected file silcd/server_backup.c.
2893 * Route packet only to one router in the function
2894 silc_server_packet_send_to_channel. Affected file is
2895 silcd/packet_send.c.
2897 * Fixed silc_server_send_notify_dest to set the broadcast
2898 flag. Fixed the silc_server_send_notify_topic to actually
2899 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2900 Affected file silcd/packet_send.c.
2902 * Changed the SFTP Filesystem interface. Changed the
2903 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2904 the filesystem operation function. The SilcSFTPFilesystem
2905 is now a context that is allocated by all filesystem allocation
2906 functions and it already includes the operations structure
2907 and filesystem specific context. It is given as argument
2908 now to the silc_sftp_server_start. This made the interface
2909 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2910 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2912 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2914 * Changed the backup router adding and getting interfaces
2915 in the server. The router that will be replaced by the
2916 specified backup router is now sent as argument. Affected
2917 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2920 * Added silc_net_addr2bin_ne to return the binary form of
2921 the IP address in network byte order. Affected files
2922 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
2924 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2926 * Check for existing server ID in silc_server_new_server
2927 and in silc_server_connect_to_router_final and remove the
2928 old entry if it exists. Affected file silcd/packet_receive.c,
2931 * Send the channel message always to only one router, either
2932 in upstream or downstream. Affected file is
2933 silcd/packet_send.c.
2935 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2937 * Wrote the definition of the backup resuming protocol to the
2938 protocol specification.
2940 * Removed one redundant channel key generation from normal
2941 server during joining procedure. Removed one redundant
2942 channel key sending from server to router during joining
2943 procedure. Affected file silcd/command.c.
2945 * Made minor bugfixes to the backup router resuming protocol.
2946 Affected file silcd/server_backup.c, server.c.
2948 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2950 * Added --disable-asm configuration option. Affected files
2951 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
2954 * Implemented the backup resuming protocol that is used to
2955 resume the primary router position in the cell after the
2956 primary router comes back online. Affected files
2957 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
2958 and silcd/server_util.[ch].
2960 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2962 * Sleep two (2) seconds after sending QUIT command to server.
2963 Affected file lib/silcclient/command.c.
2965 * Assure that if outgoing data buffer is pending do not force
2966 send any data. Affected file silcd/packet_send.c.
2968 * Assure that if outgoing data buffer is pending do not force
2969 send any data. Affected file lib/silcclient/client.c.
2971 * Implemented the backup router support when the primary router
2972 goes down. The servers and routers can now use the backup
2973 router as new primary router without loosing connectivity.
2975 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2977 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
2978 in the server to indicate disabled entry. All data read
2979 from the connection will be ignored and no data is sent
2980 for entry that is disabled. Affected files are
2981 silcd/idlist.h, silcd/server.c.
2983 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2985 * Created SFTP client and server test programs in the
2986 lib/silcsftp/tests directory.
2988 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2990 * Implemented memory filesystem (virtual filesystem) for
2991 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
2994 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2996 * Implemented the SFTP (SSH File Transfer Protocol) to the
2997 lib/silcsftp. It includes SFTP client and SFTP server
3000 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3002 * Moved lib/silccore/silcprotocol.[ch] to the
3003 lib/silcutil library.
3005 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
3006 take variable argument list pointer as argument. Affected
3007 file lib/silcutil/silcbuffmt.[ch].
3009 * Added silc_buffer_set function that is used to set data
3010 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
3011 Affected file lib/silcutil/silcbuffer.h.
3013 * Changed various routines in the core library to use the new
3014 silc_buffer_set instead of allocating new buffer only for
3017 * Added 64-bit value formatting and unformatting support to the
3018 silc_buffer_[un]format routines. Affected file is
3019 lib/silcutil/silcbuffmt.[ch].
3021 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
3022 to includes/bitmove.h.
3024 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3026 * Fixed channel user mode saving in client library. Affected
3027 file lib/silcclient/command[_reply].c.
3029 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3031 * Defined the file transfer to the SILC Protocol. Added
3032 new packet type SILC_PACKET_FTP and defined File Transfer
3033 Payload. The mandatory file transfer protocol is SFTP
3034 (SSH File Transfer Protocol). Affected file in addition
3035 of the internet draft is lib/silccore/silcpacket.h.
3037 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
3038 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
3039 is used as part of backup router protocol when the primary
3040 router of the cell is back online and wishes to resume
3041 the position as primary router.
3043 * Redefined the MAC generation keys in the protocol. The
3044 same key is not used anymore in both direction. Both
3045 direction will now use different keys for sending and
3046 receiving. This fixes a potential security flaw. This
3047 change causes incompatibilities in the protocol.
3049 * Redefined also the MAC computation from the packet.
3050 An packet sequence number is now added to the MAC
3051 computation. This prevents possible replay attacks against
3052 the protocol. This change too causes incompatibilities
3055 Added `sequence' field to the SilcPacketContext to hold
3056 the current sequence number for the packet.
3058 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3060 * Added `created' field to the SilcIDListData in the file
3061 silcd/idlist.h to indicate the time when the entry was
3064 * Added `created' field to the SilcChannelEntry too. Affected
3065 file silcd/idlist.h.
3067 * Added `creation_time' aguments to all the announcement functions
3068 in the server. If it is provided then only the entries that
3069 was created after the provided time frame are actually
3070 announced. Affected file silcd/server.[ch].
3072 * The protocol says that the Channel ID's IP address must be
3073 based on the router's IP address. Added check for this in
3074 the silc_server_new_channel when processing incoming New Channel
3075 Payload. Affected file silcd/packet_receive.c.
3077 * Print out the correct version with --version in SILC client.
3078 Affected file irssi/src/silc/core/silc-core.c.
3080 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3082 * Fixed WHOWAS command to check for completnes of the client
3083 entry always, not just when the command is coming from client.
3084 Affected file silcd/command.c.
3086 * Added new function silc_server_packet_queue_purge to purge the
3087 outgoing data queue to the network. After the function returns
3088 it is guaranteed that the outgoing packet queue is empty.
3089 Affected file silcd/packet_send.[ch].
3091 * Purge the outgoing packet queue in the rekey protocol's final
3092 callback to assure that all rekey packets go to the network
3093 before quitting the protocol. Affected file silcd/server.c.
3095 * Added silc_client_packet_queue_parse as similar function as
3096 in server to the client library. The affected file is
3097 lib/silcclient/client.c.
3099 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3101 * Splitted silcd/server.c and created silcd/server_util.[ch]
3102 for utility functions.
3104 * Added new socket flag SILC_SF_DISABLED to indicate that the
3105 connection is open but nothing can be sent to or received from
3106 the connection. Affected file lib/silcutil/silsockconn.[ch].
3107 The checking for disabled socket is checked in the low level
3108 silc_socket_write and silc_socket_read functions.
3110 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3112 * Allow only nicknames and channel names that fits into the
3113 7-bit unsigned char ASCII set. Affected file silcd/command.c.
3115 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3117 * When processing JOIN command reply in server check that if
3118 the channel exists in our global list we'll move it the local
3119 list. Affected file silcd/command_reply.c.
3121 * Fixed the check whether client is joined on the channel already
3122 in JOIN command. Affected file lib/silcclient/command.c.
3124 * Fixed the JOIN command reply to check whether the channel
3125 already exists. Affected file lib/silcclient/command_reply.c.
3127 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3129 * Added silc_ske_status_string to map the SKE error numbers
3130 to readable strings. The affected files are
3131 lib/silcske/silcske[_status].[ch].
3133 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3135 * Do not show the private channels on the WHOIS channel list
3136 as it is not allowed by the protocol. The affected file is
3139 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3141 * Assure that the packet length digged from the actual packet
3142 is something sensible in the silc_packet_decrypt_rest_special
3143 in lib/silccrypt/silcpacket.c.
3145 * Free and NULL the allocated pointer in silc_hmac_alloc if
3146 the HMAC allocation fails. The affected file is
3147 lib/silccrypt/silchmac.c.
3149 * Print the selected security properties to the log files in
3150 the server. Affected file silcd/protocol.c.
3152 * Add SKE's reference counter even if calling the completion
3153 callback manually. Otherwise it goes negative, although it
3154 does not cause any problems. The affected file is
3155 lib/silcske/silcske.c.
3157 * Remove the client entry with short timeout after giving the
3158 KILL command. Affected file lib/silcclient/command.c.
3160 * Fixed to send error reply in WHOIS and IDENTIFY commands in
3161 case all found clients are already disconnected (WHOWAS would
3162 found them) in the server. Affected file silcd/command.c.
3164 * Update the last_receive (time of last data received) to be
3165 updated only when received private or channel message so that
3166 the idle time showed in WHOIS makes more sense.
3168 * Added boolean field `valid' in to the SilcClientEntry in the
3169 client library to indicate whether the entry is valid or not.
3170 This fixes the nickname change bug on channel when changing
3171 the nickname to be same than the old (like nick to Nick) the
3172 nickname formatter doesn't set the new nick anymore to Nick@host.
3173 Affected file lib/silcclient/idlist.[ch].
3175 * Now actually fixed the nickname changing on disconnection.
3176 Added new function silc_change_nick to the Irssi SILC Client.
3177 Affected file irssi/src/silc/core/client_ops.c,
3178 irssi/src/silc/core/silc-nicklist.[ch].
3180 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3182 * Check that the public key exists in the GETKEY command before
3183 trying to encode it. Affected file silcd/command.c.
3185 * Print some notifications on received public keys with GETKEY
3186 command in the Irssi SILC Client. Affected files are
3187 irssi/src/fe-common/silc/module-formats.[ch],
3188 irssi/src/silc/core/client_ops.c.
3190 * Use IDENTIFY command to resolve the server information in the
3191 GETKEY command instead of INFO command. Affected file
3192 lib/silcclient/command.c.
3194 * All command reply functions in the client library now calls
3195 the pending command reply callbacks even if an error has
3196 occurred. The server has done this a long time and now it was
3197 time to move the client library to this as well. Now all
3198 errors can be delivered back to the pending command reply
3199 callbacks if necessary. Affected files are
3200 lib/silcclient/command[_reply].[ch].
3202 * Change the nickname on disconnection back to the username
3203 because in reconnect the server will enforce it to it anyway.
3204 Affected file irssi/src/silc/core/silc-servers.c.
3206 * Fixed a config file parsing bug in the Irssi SILC client.
3207 Affected file irssi/src/silc/core/clientconfig.c.
3209 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3211 * When printing the channel mode on JOIN, verify that the
3212 channel key and channel's HMAC are valid. Affected file
3213 irssi/src/silc/core/client_ops.c.
3215 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3217 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
3218 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
3219 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
3221 * Removed channel key rekey task deleting from the function
3222 silc_server_save_channel_key. Affected file silcd/server.c.
3223 Added explicit timeout task context instead that is used to
3224 delete the task if we are registering a new task before the
3225 new task has elapsed.
3227 * When channel key rekey occurs the client library now saves
3228 the old channel key for a short period of time (10 seconds) and
3229 is able to use it in case some is still sending channel
3230 messages encrypted with the old key after the rekey. Affected
3231 file lib/silcclient/[idlist.h|client_channel.c].
3233 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3235 * Added check to the silc_server_new_id_real to not accept
3236 new ID if it is the sender's own ID. Affected file is
3237 silcd/packet_receive.c.
3239 * Assure that we do not announce ourself or the one we've
3240 sending our announcements when we're router and are announcing
3241 servers to our primary router. Affected file silcd/server.c.
3243 * Fixed silc_server_command_identify_check_client to assemble
3244 correct WHOIS packet. It send corrupted WHOIS packet and
3245 caused problem with router to router connections. Affected
3246 file silcd/command.c.
3248 Fixed also silc_server_command_whois_check the same way
3249 as for the IDENTIFY command.
3251 * Added new SilcIDListStatus to the server in the SilcIDListData
3252 structure. The status now includes the current status of
3253 the entry (like registered, resolved etc.). Affected file
3254 silcd/idlist.[ch]. Defined a bunch of different status types
3255 as well. This replaced the old boolean registered field as well.
3257 Added resolve_cmd_ident field to the SilcClientEntry structure
3258 too so that if the entry is for example being resolved so
3259 another command may attach to the same pending command reply
3260 without requiring to resolve the same entry again. This concept
3261 should optimize the WHOIS and the IDENTIFY resolving under
3262 heavy load by taking away unnecessary resolving for entries
3263 that are being resolved already.
3265 Added support for adding multiple pending commands for one
3266 command idenfier. Affected file silcd/command[_reply].[ch].
3268 * Fixed WHOIS and IDENTIFY save to remove the cache entry
3269 before deleting the data. Otherwise the hash table will have
3270 freed data in comparison functions. Affected file is
3271 silcd/command_reply.c.
3273 * Fixed silc_idlist_replace_client_id to add the new entry to
3274 the cache with NULL nickname. Otherwise there will be invalid
3275 memory as the nickname after the nickname is freed. Affected
3276 file silcd/packet_receive.c.
3278 * Fixed the silc_idlist_get_clients_by_hash. The entries was
3279 saved into wrong slots because the previous number of entries
3280 was not taken into account. Affected file silcd/idlist.c.
3281 Fixed same thing in silc_idlist_get_clients_by_nickname too.
3283 * If we are router and we receive JOIN notify to a channel that
3284 does not have any users then notified client is marked as the
3285 channel founder, as it is it. The affected file is
3286 silcd/packet_receive.c
3288 * Added to the extended hash table API's table_del_*ext functions
3289 the destructor as argument too, so that the caller can decide
3290 which destructor to use or whether to use destructor at all.
3291 Affected file lib/silcutil/silchashtable.[ch].
3293 * Fixed ID Cache purging. It actually deleted the entries from
3294 the hash table after the data was freed. The hash table ended
3295 up comparing freed memory. The affected file is
3296 lib/silccore/silcidcache.c.
3298 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3300 * Fixed Irssi SILC client's KILL command's HELP syntax.
3302 * The USERS command now resolves the detailed user information
3303 if the userinfo field is missing. Affected file is
3304 lib/silcclient/command_reply.c.
3306 * Do not print error in silc_file_read if the read file does
3307 not exist. Just silently return NULL. Affected file is
3308 lib/silcutil/silcutil.c.
3310 * Fixed the silc_log_output to not wine about NULL filename
3311 and to not create some bogus " " filename. Affected file is
3312 lib/silcutil/silclog.c.
3314 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3316 * Fixed various printing bugs on the user interface in the
3317 Irssi SILC Client. Minor changes that were forgotten from
3320 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3322 * Fixed the configure.in.pre and the compilation and distribution
3323 environment to support the new autoconf 2.52. That version is
3324 now required to compile the CVS trunk.
3326 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3328 * Renamed function silc_parse_nickname to silc_parse_userfqdn
3329 to generally parse user@fqdn format strings. Affected file
3330 lib/silcutil/silcutil.c.
3332 * Added nickname_format and nickname_force_format fields to the
3333 SilcClientParams structure. The first one defines the format
3334 for the nicknames that the library will enforce if the receives
3335 multiple same nicknames. The second one is boolean value and
3336 can be used to force the library to always enforce the format
3337 to the nicknames regardles whether there are multiple nicknames
3338 or not. This configurable formatting was employed to flexibly
3339 support accessing multiple nicknames from the user interface.
3340 The userinterface can now set the nicknames to what ever format
3341 they prefer. Affected file lib/silcclient/silcapi.h.
3343 Added function silc_client_nickname_format to the file
3344 lib/silcclient/idlist.c. It performs the nickname formatting.
3346 Added new field `hostname´ to the SilcClientEntry context.
3347 It holds the hostname of the client. Affected file is
3348 lib/silcclient/idlist.h.
3350 * Irssi SILC Client sets the nicknames in nick@hostn format.
3351 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
3352 irssi/src/silc/core/silc-core.c.
3354 The WHOIS printing now also shows both the real nickname and
3355 the formatted nickname so that user knows how to access the
3356 user if there are multiple same nicknames cached. Affected
3357 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
3358 printing formatting too to take the hostname now as a separate
3359 argument. The Affected file is
3360 irssi/src/fe-common/silc/modules-formats.[ch].
3362 * Changed the silc_client_get_clients_local to accept the formatted
3363 nickname as argument. It accepts the real nickname too but the
3364 formatted nickname can be used to find the true entry from
3365 multiple entries. Affected file lib/silcclient/silcapi.h and
3366 lib/silcclient/idlist.c.
3368 * Added nickname_format_parse field to the SilcClientParams.
3369 It is a callback function provided by the application to parse
3370 the nickname out of the formatted nickname string. The library
3371 calls it to get the nickname from the formatted string. Since
3372 the application generally knows better the format of the nickname
3373 string it parses it instead of the library, even though library
3374 encodes the formatted string. If the callback function is not
3375 provided then the library will use the string as is. The
3376 affected file is lib/silcclient/silcapi.h.
3378 * All the nickname strings passed to the client library in
3379 commands are now expected to be formatted nickname strings.
3380 If the command does not support the formatted nickname string
3381 it will assume that the sent string is the actual nickname.
3382 Affected file lib/silcclient/command.c.
3384 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3386 * Added public key authentication support to OPER and SILCOPER
3387 commands in the client library. Affected file is
3388 lib/silcclient/command.c.
3390 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3392 * Changed the get_auth_methdod client operation to be asynchronous.
3393 It can be async if the application resolves the authentication
3394 method from the server during the negotiation. Added new
3395 SilcGetAuthMeth completion callback that the application will
3396 call after resolving the authentication method.
3398 Added function silc_client_request_authentication_method that
3399 the application can use to resolve the authentication method
3400 from the server. Added also SilcConnectionAuthRequest callback
3401 that the library will call after the server has replied. The
3402 application can call this function if it does not know the
3403 current authentication method.
3405 Affected files are lib/silcclient/client.c and
3406 lib/silcclient/silcapi.h.
3408 * The Irssi SILC client now automatically resolves the authentication
3409 method incase any configuration information is not present (and
3410 currently there never is). The affected file is
3411 irssi/src/silc/core/client_ops.c.
3413 * Fixed public key authentication from the client library.
3414 Affected file lib/silcclient/protocol.c. Changed also the
3415 protocol specification about the public key authentication in
3416 the connection authentication protocol. The actual data to be
3417 signed is now computed with a hash function before signing.
3419 * Fixed the public key authentication from the server as well.
3420 Affected file silcd/protocol.c.
3422 * Removed the mlock()'s from the memory allocation routines.
3423 Affected file lib/silcutil/silcmemory.c. The ./configure does
3424 not check anymore for the mlock(). Affected file is
3427 * Fixed USERS command in server to allow the execution of the
3428 command for private and secret channels if the client sending
3429 the command is on the channel. Affected file silcd/command.c.
3431 * Fixed silc_client_get_clients_local to return the clients
3432 count correctly. It could return wrong value. Affected file
3433 lib/silcclient/idlist.c.
3435 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3437 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
3438 types. The assembler optimizations seemed not to like 64-bit
3439 data types. The assmebler optimizations thus are now enabled
3440 also for BSD systems as opposed to only enable them for Linux.
3442 * Do not check for threads at all on BSD systems. Affected
3443 file configure.in.pre.
3445 * Removed -n and -h options from the Irssi SILC Client since
3446 they are not used in silc.
3448 * Fixed the prime generation to assure that the first digit
3449 of the generated random number is not zero since our conversion
3450 routines does not like number strings that starts with zero
3451 digit. If zero digit is seen the random number is regenerated.
3452 This caused some corrupted RSA keys when the zero first digit
3453 was met. Affected file lib/silcmath/silcprimegen.c.
3455 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3457 * Fixed WIN32 configuration in the ./configure script.
3458 Fixed to include xti.h on environments that has it.
3459 Patches by Carsten Ilchmann and andrew.
3461 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3463 * Changed the silc_id_create_client_id to be collision
3464 resistant. It is now assured that there cannot be created
3465 two same client ID's. I suspect that some weird bugs in
3466 the server were actually caused by duplicate Client IDs.
3467 Affected file silcd/serverid.[ch]. A router receiving
3468 new ID now also assures and informs the sending server
3469 if the ID caused collision.
3471 * Changed the silc_id_create_channel_id to also assure that
3472 there are no collisions.
3474 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3476 * Statement about ignoring the Mutual Authentication flag when
3477 performing rekey with PFS was a bit misleading. It is ignored
3478 if it was set in the initial negotiation, it cannot be even
3479 set in the rekey. Fixed in the ke-auth draft. Started the
3480 new versions of the protocol drafts in the doc/.
3482 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3484 * Fixed a bug in silc_client_command_identify_save when saving
3485 new channel information. The channel name was no duplicated
3486 and caused crash on exit. Affected file is
3487 lib/silcclient/command_reply.c.
3489 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3491 * Fixed the getkey command handling in the server. Send just
3492 empty OK reply to the sender if the key could not be fetched
3493 (but everything else was ok, like the key just was not available).
3494 Changed the public key parameter to optional in the protocol
3495 specs so that empty OK reply can be sent. Affected file
3498 Added a message to Irssi SILC client to tell to user if the
3499 server did not return a public key.
3501 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3503 * Fixed a channel key regeneration bug. It registered new
3504 timeout tasks exponentially until all system resources were
3505 used. Affected file silcd/server.c.
3507 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3509 * Added the SILC Document generator to the scripts/silcdoc.
3510 It can be used to generate the Toolkit Reference Manual out
3511 of the source tree. Internally it will also use the RoboDoc
3512 generator now imported in util/robodoc.
3514 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3516 * Added couple of return's in rekey protocol if error orccurred
3517 during the protocol. The execution must be terminated.
3518 Affected file silcd/protocol.c. Also, terminate the protocol
3519 always with timeout.
3521 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3523 * The client's Client ID was created initally from the wrong
3524 nickname (it could have been in format nick@host) in the
3525 silc_server_new_client. Affected file silcd/packet_receive.c
3527 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3529 * Added some SILC_LOG_ERROR's to various error conditions
3530 if client could not be added to ID cache. Affected files
3531 silcd/packet_receive.c and silcd/server.c.
3533 * When client's sock->user_data is freed, NULL also the
3534 client->router and client->connection pointers. Added check
3535 for these pointers being NULL to various places around the
3536 code. Affected file silcd/server.c.
3538 * Added client->data.registered == TRUE checks to various
3539 places around the code to assure that unregistered client's
3540 are not handled when it is not allowed. Affected file
3543 * Added `bool registered' fields to all
3544 silc_idlist_[server|client]_get_* routines to indicate whether
3545 the fetched client needs to be registered or not. Affected
3546 file silcd/idlist.[ch].
3548 * Add your own entry as registered to the ID cache in the
3549 server. Affected file server.c.
3551 * Fixed a bug in silc_server_new_server. The SilcServer was
3552 set as the new server's context instead of SilcServerEntry.
3553 This naturally caused some weird bugs.
3555 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3557 * Do not delete the channel rekey task when adding it
3558 for in silc_server_create_channel_key.
3560 * Changed the silc_server_create_channel_key to return
3561 TRUE or FALSE to indicate the success of the channel key
3564 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3566 * Fixed MSVC++ project files and added missing files to
3567 Makefiles under win32/.
3569 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3571 * Do not add TCP_NODELAY flag if the operating system
3572 does not have it defined. Affected files are
3573 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3575 * Fixed buffer overflow from Irssi SILC Client. Affected
3576 file irssi/src/fe-common/core/themes.c.
3578 * Fixed double free in client library in the file
3579 lib/silcclient/client.c when disconnecting from server.
3581 * Applied double free patch from cras to Irssi SILC client.
3582 Affected files irssi/src/core/[modules/expandos].c
3584 * Fixed the disconnection handling to Irssi SILC Client.
3585 The application must call silc_client_close_connection
3586 in ops->connect client operation in case of failure of
3587 the connection. Affected file is
3588 irssi/src/silc/core/client_ops.c.
3590 * Do not set sock->protocol to NULL in the function
3591 silc_client_close_connection after executing the protocol's
3592 final callback since the sock might not be valid anymore.
3593 Affected file lib/silcclient/client.c.
3595 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3597 * Do not enable SILC_THREADS if the linking with libpthread
3598 did not happen. Affected file configure.in.pre.
3600 * Added notion to protocol specification that server must
3601 verify the sent authentication payload with CMODE when
3602 setting the channel founder key. Implemented it to the
3603 server. Affected file silcd/command.c.
3605 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3607 * Added _EXTRA_DIST SILC distribution variable to the
3608 distributions file. It is used to conditionally add extra
3609 files or directories to the specific distribution. Affected
3610 files ./prepare, Makefile.am.pre and distributions.
3612 Removed the `_' from the start of the distribution names.
3615 * Added README.WIN32 for instructions to compile the Toolkit
3618 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3620 * Fixed a double free in disconnection in the server. Affected
3621 file is silcd/server.c.
3623 * Fixed the lib/silcske/groups.c to work now also with GMP
3624 MP library. The string conversion did not work when using
3625 specific base and the base is indicated in the string as well.
3627 * Created win32/ directory which now includes MSVC++ specific
3628 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3629 It will appear only in the toolkit distribution
3631 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3633 * Changed the key material distribution function in case when
3634 the hash output is too short. The data is now concatenated
3635 a bit differently than it used to. Made the change to the
3636 SKE protocol specification.
3638 * Added better GMP detection to configure.in.pre. A patch
3641 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3643 * Fixed a minor bug in SKE that might cause some problem on
3644 some platforms. Affected file lib/silcske/silcske.c.
3646 * Added the cookie checking for initiator in the SKE. It checks
3647 that the responder returns the sent cookie unmodified. The
3648 affected file is lib/silcske/silcske.c. Added new SKE
3649 error type INVALID_COOKIE that can be sent during the
3650 negotiation. Fixed some memory leaks as well.
3652 * Added the "invalid cookie" error message to Irssi SILC client's
3655 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3657 * Added `task_max' field to the SilcClientParams to indicate
3658 the maximum tasks the scheduler can handle. If set to zero,
3659 default values are used. Affected file lib/silcclient/silcapi.h.
3661 * Fixed memory leaks in silc_client_close_connection. Affected
3662 file lib/silcclient/client.c.
3664 * Added silc_client_del_client_entry to client library to free
3665 all memory of given client entry. Affected file is
3666 lib/silcclient/idlist.[ch].
3668 * Added new functions silc_client_del_channel and
3669 silc_client_del_server to delete channel and server entries.
3670 Affected file lib/silcclient/[silcapi.h/idlist.c].
3672 * Removed silc_client_del_client_by_id from silcapi.h.
3674 * Fixed the INFO command to return the server's own info
3675 correctly when querying by Server ID. Affected file is
3678 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3680 * Removed the non-blocking settings in WIN32 code in the
3681 silc_sock_[read/write] and added SleepEx instead. Affected
3682 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3683 of input data is now checked with FIONREAD and ioctlsocket.
3685 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3687 * Call silc_schedule_task_del_by_context in the
3688 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3689 Affected file lib/silccore/silcprotocol.c.
3691 * Call silc_protocol_cancel for active protocols in the
3692 silc_server_close_connection if the funtion
3693 silc_server_free_sock_user_data has not been called.
3694 Affected file silcd/server.c.
3696 * Generic tasks cannot be deleted using the del_by_fd
3697 task deleting function since generic tasks does not match
3698 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3700 * Added a notion to SILCOPER help file that the SILCOPER works
3701 only on router server, not on normal server.
3703 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3705 * Added for WIN32 support for the new scheduler as well.
3706 Affected file lib/silcutil/win32/silcwin32schedule.c.
3708 * Fixed the SHA1 implementation to work on various platforms.
3710 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3712 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3713 API. It is part of the scheduler now. Everything else is
3714 as previously but some functions has changed their names.
3715 Checkout the lib/silcutil/silcschedule.h for the interface.
3716 Updated all applications to use the new interface. Affected
3717 files are lib/silcutil/silcschedule.[ch].
3719 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3721 * Found a bug in the SKE implementation. The HASH value,
3722 specified by the protocol, was not computed correctly. The
3723 public key of the responder was not added to the computation
3724 even though it is mandatory. Affected file lib/silcske/silcske.c.
3725 This unfortunately causes incompatibilities with older
3726 clients and servers.
3728 * Added WIN32 specific network init and uninit functions:
3729 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3730 the Winsock2. Affected file lib/silcutil/silcnet.h and
3731 lib/silcutil/win32/silcwin32net.c.
3733 * Set the socket always to nonblocking mode on WIN32 after
3734 reading data or writing data. Affected file is
3735 lib/silcutil/win32/silcwin32sockconn.c.
3737 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3739 * Fixed various compilation problems under WIN32. Affected
3740 files lib/silcutil/win32/silcwin32thread.c and
3741 lib/silcutil/win32/silcwin32schedule.c.
3743 * Removed all _internal.h #includes from public header
3744 files. Internal headers must never be included from
3747 Removed also the lib/silcske/payload_internal.h file.
3749 * All include files that may be needed (public and some others
3750 included by the public headers) by application developers are
3751 now copied to the ./includes directory. It does not copy any
3752 internal headers. Affected file Makefile.defines.pre and all
3753 Makefile.am's under lib/ and subdirs.
3755 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3757 * Do not change the ~/.silc directory's permissions automatically.
3758 Affected file irssi/src/silc/core/clientutil.c.
3760 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3762 * Do not cancel the protocol in silc_server_close_connection
3763 it might cause recursion. Now cancelled in the function
3764 silc_server_free_sock_user_data. Affected file silcd/server.c.
3766 * Fixed the silc_server_remove_clients_by_server to regenerate
3767 the channel keys correctly finally. Added also new function
3768 silc_server_remove_clients_channels to actually do it.
3769 Affected file silcd/server.c.
3771 * Fixed the silc_server_new_channel to not crash by giving
3772 wrong router to the new channel. Affected file is
3773 silcd/packet_receive.c.
3775 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3777 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3778 which is given as argument to the silc_client_alloc now.
3779 It can be used to configure the client and set various parameters
3780 that affect the function of the client.
3782 * The USERS command in server did not check whether the channel
3783 is private or secret. Affected file silcd/command.c.
3785 * Added new argument to the USERS command in protocol specification.
3786 The USERS command now can take the channel name as argument
3787 as well. Added support for this in client and server and
3788 updated the protocol specs.
3790 * Completed the GETKEY command in client. It can be now used
3791 to fetch also servers public key not only some clients.
3792 Affected files lib/silcclient/command[_reply].c.
3794 * Added silc_client_get_server to return server entry by the
3795 server name. Affected files lib/silcclient/silcapi.h and
3798 * Redefined the IDENTIFY command in protocol specification to be
3799 more generic. It now can be used to query information about
3800 any entity in the SILC Network, including clients, servers and
3801 channels. The query may be based either the entity's name
3802 or the ID. Added support for this in both client and server.
3804 Affected files silcd/command.c and lib/silcclient/command.c
3805 and command_reply.c.
3807 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3808 the _from_client and _from_server functions. Affected file
3811 * Added silc_client_get_channel_by_id_resolve to the file
3812 lib/silcclient/silcapi.h to resolve channel information by
3813 its ID. Added also silc_client_get_channel_by_id that
3814 does not resolve it from the server.
3816 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3818 * Added SilcServerEntry context into the client library
3819 to represent one server. The INFO command now allocates
3820 these to save the resolved server info. For now on the
3821 client library will also keep information about servers,
3822 connected and resolved with INFO.
3824 The INFO command now allocates the SilcServerEntry context
3825 and saves the server info there. The COMMAND_REPLY in
3826 the INFO now returns the parameters to application in
3827 same order as defined in the protocol specification.
3829 The entries are cached in the client->server_cache.
3831 * The INFO command is now issued after received the Client ID
3832 from the server. Affected file lib/silcclient/client.c.
3834 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3835 to the application as the mode changer might be server.
3836 It is guaranteed that NULL is not returned anymore to the
3837 application. Affected file lib/silcclient/client_notify.c.
3839 The ID Type is now also passed to the application so that
3840 it can check whether the returned entry is SilcClientEntry
3843 Added new function silc_client_get_server_by_id to return
3844 the server entry by ID. Affected files are the
3845 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3847 * Do not create the channel in the Irssi SILC Client when issuing
3848 the JOIN command but when received the sucessful JOIN command
3849 reply. Otherwise the channel might get created even though we
3850 could not join it. The Affected file is
3851 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3853 * Fixed a channel joining bug in router. The router must also
3854 check the channel modes, invite and ban lists etc. when serving
3855 the JOIN command sent by normal server. Affected file is
3856 silcd/command.c. The router now resolves the client's
3857 information from the server who sent the JOIN command if it
3858 does not know it, and processes the JOIN command only after
3861 * Changed the SilcCommandCb to take new argument; void *context2.
3862 Affected file lib/silccore/silccommand.h
3864 The second argument in the command callbacks in the server now
3865 includes the SilcServerCommandReplyContext if the command was
3866 called as pending command callback from the command reply.
3867 Otherwise it is NULL. When called as pending the status of the
3868 command reply will be checked and if it was erronous the
3869 error will be sent to the original sender of the command.
3870 This way the client always receives the error messages even
3871 though the server was actually the one who received the error
3872 when it resent the command to router, for example. Affected
3873 files silcd/command[_reply].[ch].
3875 * Fixed sending WHOWAS command's error message to client if
3876 the requested client could not be found. It was missing.
3879 * Changed the CMODE and CUMODE commands reply arguments in the
3880 protocol specification. The Channel ID is now sent in both
3881 of the commands to identify the channel. Implemented this
3882 new feature to the client and server. Affected files
3883 lib/silcclient/command_reply.c and silcd/command.c.
3885 * Made better checks for invite and ban lists in the JOIN
3886 command in server. Affected file silcd/command.c.
3888 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3890 * The server now performs the incoming host IP/DNS lookup
3891 using the silc_socket_host_lookup and thus does not block
3892 the server anymore. Affected file silcd/server.c.
3894 * Completed the multi-thread support for SILC Scheduler in
3895 the lib/silcutil/silcschedule.c.
3897 * Fixed the configure.in.pre to detect the pthread correctly
3900 * Fixed a deadlock in silc_task_queue_wakeup in the file
3901 lib/silcutil/silctask.c.
3903 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3905 * Added new function silc_schedule_wakeup that is used in
3906 multi-threaded environment to wakeup the main thread's
3907 schduler. It needs to be used when a thread adds a new task
3908 or removes a task from task queues. After waking up, the
3909 scheduler will detect the task queue changes. If threads
3910 support is not compiled in this function has no effect.
3911 Implemented the wakeup mechanism to both Unix and WIN32
3912 systems. Affected files are lib/silcutil/silcschedule.[ch],
3913 lib/silcutil/unix/silcunixschedule.c and the
3914 lib/silcutil/win32/silcwin32schedule.c.
3916 * Added new function silc_task_queue_wakeup to wakeup the
3917 scheduler by the specified task queue. Affected file
3918 lib/silcutil/silctask.[ch].
3920 * The silc_socket_host_lookup_start now wakes up the scheduler
3921 after adding the timeout task. Affected file is
3922 lib/silcutil/silcsockconn.c.
3924 * The silc_socket_host_lookup is synchronous now if the threads
3925 support is not compiled in. However, the callback is still
3926 called asyncronously through the scheduler, anyway. Affected
3927 file lib/silcutil/silcsockconn.c.
3929 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3931 * Added new function silc_socket_host_lookup to perform
3932 asynchronous IP and FQDN lookups for the socket connection.
3933 Affected files lib/silcutil/silcsockconn.[ch].
3935 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3937 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3938 that may or may not compile the mutex support in.
3940 Changed the silc_mutex_alloc interface. It allocates the
3941 mutex now to the sent pointer and returns TRUE or FALSE.
3943 Affected file lib/silcutil/silcmutex.h.
3945 * Wrote the SILC Task Queue interface to support multi-threads.
3946 Affected file lib/silcutil/silctask.[ch].
3948 * Wrote the SILC Scheduler to support multi-threads. Affected
3949 file lib/silcutil/silcschedule.c.
3951 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3953 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3954 in lib/silcutil/win32/.
3956 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3958 * Defined SILC Mutex API and SILC Thread API and implemented
3959 them for Unix. Affected files are
3960 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3961 lib/silcutil/unix/silcunixmutex.c and
3962 lib/silcutil/unix/silcunixthread.c.
3964 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3966 * Fixed the silc_server_remove_clients_by_server's channel
3967 key re-generation. The hash table handling was incorrect
3968 and would not work with many channels. Affected file is
3971 * Fixed some memory leaks around the server code.
3973 * Rewrote the silc_server_get_users_on_channel to support IPv6
3974 based Client ID's. Affected file silcd/server.c.
3976 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3977 specification. However, a separate document must be written
3978 to define the detailed signing procedure and the payload
3979 associated with the flag. Defined the flag to the
3980 lib/silccore/silcchannel.h as well.
3982 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3984 * Changed the dynamic tables to static size tables in the
3985 lib/silccrypt/silchmac.c.
3987 * Removed GCC dependencies from the code. A patch by cras.
3989 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3991 * Do not show the error "Error receiving packet bla bla"
3992 in server if it really was not an error (-2 means that reading
3993 is pending). Affected file silcd/server.c.
3995 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3997 * Fixed a possible crash in silc_server_remove_clients_by_server
3998 in silcd/server.c. Fixed there also some memory leaks.
4000 * Fixed the silc_idlist_replace_client_id. It could replace
4001 wrong key in the hash table. Affected file silcd/idlist.c.
4003 * Do not check whether there are global users on the channel
4004 if the channel->global_users is FALSE. Affected functions
4005 silc_server_remove_from_one_channel and
4006 silc_server_remove_from_channels in silcd/server.c. Also,
4007 do not check if the removed client is local as we can be
4008 sure that global client was not removed from the channel
4009 and checking for global users is not needed.
4011 * The silc_server_remove_clients_by_server now re-generates
4012 the channel keys correctly for those channels that had
4013 clients removed from them. Affected file silcd/server.c.
4015 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4017 * Found the reason of random crashes in the server. We weren't
4018 ignoring the SIGPIPE signal (which can be sent in write())
4019 and it crashed the server. Affected file silcd/silcd.c.
4021 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4023 * Assure that sock->user_data is not NULL in the function
4024 silc_server_packet_send in silcd/packet_send.c.
4026 * Disconnect the remote connection if it could not be added
4027 to any ID lists in the server. The affected file is
4030 * Check in silc_server_packet_send[_real/dest] that the
4031 socket is not disconnecting and ignore the data if it is.
4032 Affected file silcd/packet_send.c.
4034 * Define inline to __inline on native WIN32 compilation.
4035 Affected file includes/silcwin32.h.
4037 * Added some explicit type casts for inline code since MSVC
4038 require them. Affected files lib/silcutil/silcbuffer.h,
4039 lib/trq/silcdlist.h and lib/trq/silclist.h.
4041 * Print warning in log files from now on if the packet
4042 decryption fails. Affected file silcd/server.c.
4044 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4046 * Changed the `say' client operation's interface to accept
4047 new `type' argument to indicate the type of the message sent
4048 by the library. The application may filter the library's
4049 messages according the type. The affected file is the
4050 lib/silcclient/silcapi.h.
4052 * Added two new functions to lib/silcclient/silcapi.h:
4053 silc_client_del_client and silc_client_del_client_by_id.
4054 Affected file lib/silcclient/idlist.c.
4056 * Moved the clientincludes.h from includes/ to silc/ and
4057 serverincludes.h from includes/ to silcd/.
4059 * The modes for the CMODE and CUMODE are now passed as
4060 uint32 for application with COMMAND_REPLY. The affected
4061 file is lib/silcclient/command_reply.c.
4063 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4065 * /WHOIS without arguments shows client's own information.
4066 Affected file lib/silcclient/command.c.
4068 * Changed PING to not accept any arguments. The specs
4069 says that client can ping only the connected server so
4070 requiring an argument is not needed. Affected file is
4071 lib/silcclient/command.c.
4073 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4075 * Fixed a fatal bug in private message sending and reception
4076 encryption and decryption when using private message keys.
4077 The implementation was incorrect and did not follow the
4078 specification. It causd that some of the message were
4079 lost since it did not use the sending and receiving keys
4080 as the protocol suggests. This has been fixed and will cause
4081 incompatibilities with older clients when sending private
4082 message encrypted with private message keys. Affected files
4083 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
4084 and various other in Irssi SILC Client.
4086 Added `responder' boolean argument to the functions
4087 silc_client_add_private_message_key[_ske] to indicate when
4088 the key is added as responder or initiator of the key
4091 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4093 * Removed the silc_ske_check_version function and created
4094 a SilcSKECheckVersion callback. Added also a function
4095 silc_ske_set_callbacks that is now used to set all SKE
4096 callbacks. The callback functions are not given to
4097 the SKE functions anymore, but this function is used to
4100 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
4102 * Added `silc_version' argument to the silc_client_alloc
4103 to define the version of the application for the library.
4104 The library will use the version string to compare it
4105 against the remote host's (usually a server) version
4106 string. Affected file lib/silcclient/silcapi.h
4108 * Added the KE protocol context to Key Agreement context
4109 in client library so that we can abort the SKE if it
4110 is in process when we get timeout. Affected file is
4111 lib/silcclient/client_keyagr.c.
4113 * Do not resolve the client ID forever if it returns in the
4114 first time that such client does not exist. This was done
4115 for example with private message. Affected file is
4116 lib/silcclient/client_prvmsg.c.
4118 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4120 * Do not add regex.h for WIN32. The affected file
4121 includes/silcincludes.h.
4123 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
4124 not work yet 100%. It generates the DLL's automatically
4125 when compiling with --with-win32 under cygwin.
4127 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4129 * lib/contrib/regex.c is not compiled on WIN32.
4131 * Added silc_net_get_socket_opt function to the
4132 lib/silcutil/silcnet.h.
4134 * Added includes/silcwin32.h for WIN32 specific includes
4137 * Do not use ptime structure or any of the posix process
4138 functions on WIN32 in lib/silccrypt/silrng.c.
4140 * Added silc_gettimeofday to provide generic function
4141 for struct timeval on all platforms. Added the function
4142 to lib/silcutil/silcutil.h.
4144 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4146 * Moved the lib/silccore/silcsockconn.[ch] to the utility
4147 library as they clearly belong there. As a plus side we
4148 can make the actual socket connection routines platform
4151 Added also new generic function silc_socket_read and
4152 silc_socket_write (that used to be silc_packet_[read/write].
4153 The implementation of these are platform specific.
4155 * Added WIN32 specific routines of silc_socket_[read/write]
4156 to lib/silcutil/win32/silcwin32sockconn.c.
4158 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4160 * Added preliminary support for native WIN32 compilation under
4161 cygwin (using the -mno-cygwin option for GCC) to the
4162 ./configure.in.pre. The --with-win32 now prepares the
4163 compilation for native WIN32.
4165 * Rewrote the SILC Scheduler interface in the file
4166 lib/silcutil/silcschedule.h. The scheduler is now context
4167 based and does not have anymore any global static scheduler.
4168 Moved the Unix scheduler to the lib/silcutil/unix/ directory
4169 and created lib/silcutil/win32 directory for WIN32 based
4172 * Added Unix specific network routines to the
4173 lib/silcutil/unix/silcunixnet.c and the old
4174 lib/silcutil/silcnet.c includes now only generic routines.
4176 Added WIN32 specific network routines to the
4177 lib/silcutil/win32/silcwin32net.c.
4179 * Added Unix specific utility functions from the
4180 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
4182 * Added WIN32 SILC Scheduler to the file
4183 lib/silcutil/win32/silcwin32schedule.c. The code is of course
4186 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4188 * Do not handle JOIN notify in the server if the target client
4189 is not registered (idata->registered == FALSE). The affected
4190 file is silcd/packet_receive.c.
4192 * Update the nickrec->founder in event_cumode in the Irssi SILC
4193 client. Affected file irssi/src/silc/core/silc-channels.c.
4195 * Fixed the CUMODE_CHANGE notify handling in the server when
4196 server and router are announcing their clients on channels.
4197 Now the mode changes are saved and notified correctly. The
4198 affected file is /silcd/packet_receive.c.
4200 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
4201 They really did not replace the cache entry in the ID Cache.
4202 Now they do that. Affected file silcd/idlist.c.
4204 * Fixed the KICK notify handling in the Irssi SILC client to
4205 update the channel records so that the kicked client does not
4206 appear to be on the channel. The affected file is
4207 irssi/src/silc/core/silc-channels.c.
4209 * Always update the conn->current_channel when executing command
4210 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
4212 * Fixed the KILL notify handling in Irssi SILC client to remove
4213 the killed client on all channels.
4215 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4217 * Fixed the silc_parse_command_line to remove extra spaces
4218 from the start and end of the arguments. Affected file is
4219 lib/silcutil/silcutil.c.
4221 * Cancel and free any active protocol in the function
4222 silc_server_close_connection. Affected file silcd/server.c.
4224 * Cancel and free any active protocol in the function
4225 silc_client_close_connction. Affected file is
4226 lib/silcclient/client.c.
4228 * Do not execute the KILL command for clients that are in
4229 history (ie. they are not in the network). Affected file is
4232 * Fixed KILL notify handling, client does not crash anymore.
4233 Affected file irssi/src/silc/core/silc-channels.c.
4235 * Reduced the default packet buffer size from 2048 to 1024 in
4236 lib/silccore/silcpacket.c.
4238 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
4239 counter to the SKE context that is incresed when the SKE library
4240 performs async operation outside the library. If the outside
4241 process frees the SKE context and FREED status will be set
4242 and the library will detect after the sync operation that the
4243 libary is freed. The affected files are
4244 lib/silcske/silcske[_status].[ch].
4246 * Resolve the client entry information in the function
4247 silc_client_channel_message to assure that NULL pointer is not
4248 passed as client entry to the application. */
4250 * Fixed the task timeout calculation to assure that there is
4251 never negative timeouts. The affected file is
4252 lib/silcutil/silcschedule.c.
4254 * Fixed the channel user mode notification sending in server.
4255 It was sent point-to-point to the router (or to server by router)
4256 but it needs to be destined to a channel. The routines now
4257 supports sending the channel user mode notifys to the channels
4258 when announcing clients and channels. Affected files are
4259 silcd/server.c and silcd/packet_receive.c.
4261 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
4262 It did not actually replace the old channel entry in the cache.
4263 Affected file lib/silcclient/client_notify.c.
4265 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4267 * Fixed a possible crash in silc_packet_send_prepare. It now
4268 assures always that there is enough space in the buffer and
4269 at the tail area of the buffer (for MAC).
4271 Fixed the inbound buffer reallocation in silc_packet_read.
4272 It was old code and did not handle the reallocation correctly.
4275 The affected file is lib/silccore/silcpacket.c.
4277 * Fixed buffer overflow in silc_parse_nickname in the file
4278 lib/silcutil/silcutil.c.
4280 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4282 * make install generates new server keys only if there is not
4285 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4287 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
4288 Added check that if the NOREPLY is set then we will not send
4289 the away message. This avoids infinite loop of away messages
4290 if both clients are away. The affected file is
4291 lib/silcclient/client_prvmsg.c.
4293 * Fixed client crash if /NICK was given without arguments.
4294 Affected file lib/silcclient/command.c.
4296 * Server does not send the invite list in INVITE command back
4297 to the client if the list was not altered. Added this notion
4298 to the protocol spec as well. Affected file silcd/command.c.
4300 Fixed possible crash in INVITE command by checking the
4301 value of silc_server_get_client_route command.
4303 * Fixed the INVITE notify type handling. The arguments are now
4304 taken in correct order and client does not crash. The affected
4305 file is irssi/src/silc/core/silc-channels.c.
4307 Removed the "Inviting xxx to channel" message from the
4308 client library away and let the application handle it.
4309 Affected file lib/silcclient/command.c. Added that message
4310 to Irssi SILC client's message formats.
4312 * Fixed CMODE command crash in client. It now checks the
4313 amount of arguments correctly and does not crash. The affected
4314 file is lib/silcclient/command.c.
4316 * Do not create new channel automatically in silc_channels_join
4317 but check whether the channel by that name already exists.
4318 Affected file irssi/silc/core/silc-channels.c.
4320 * Do not send the SERVER_SIGNOFF to router if the disconnected
4321 entity was the router. Affected file silcd/server.c.
4323 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
4324 SILC client as it was missing from there.
4326 Added the handling of the KICK notify to the Irssi SILC client
4327 as it was missing. Added "you have been kicked" message to
4328 Irssi SILC client's message modules formats.
4330 Added the handing of the KILL notify to the Irssi SILC client
4331 as it was missing. Added the kill message module formats
4334 The affected file is irssi/src/silc/core/silc-channels.c.
4336 * The router did not save the channel mode the server announced.
4337 Affected file silcd/packet_receive.c.
4339 * Fixed a possible crash in INFO command in server. If the
4340 server did not provide the server info it crashed. Affected
4341 file silcd/command.c.
4343 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4345 * Fixed the GETKEY command in the server to check also the
4346 global list. Otherwise the GETKEY would not work correctly
4347 in normal SILC server. Affected file silcd/command.c.
4349 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4351 * Fixed GETKEY crash, it crashed if the command did not succseed.
4353 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4355 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
4356 is now real and not just an macro interface to GMP.
4358 Removed the entire GMP from the source tree and imported new
4359 NSS MPI library instead. Reason for removing GMP is that it is
4360 extremely large and compiles extremely slow. The NSS MPI
4361 is only a few files and compiles in less than 10 seconds.
4362 The speed is also about the same as GMP. The MPI is imported
4363 to lib/silcmath/mpi.
4365 If the system has GMP installed we will still use the GMP.
4366 If it is not then the NSS MPI will be compiled.
4368 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4370 * Merged a long nickname (127 characters long) crash bugfix from
4371 Irssi CVS tree. Affected file irssi/src/core/misc.c.
4373 * Merged a freed memory reference bugfix from Irssi CVS tree.
4374 Affected file irssi/src/core/commands.c.
4376 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4378 * Added the server's public key sving and verification to the
4379 server when performing the SKE. This was missing and the
4380 remote server's (or router's) public key was accepted without
4381 checking whether we have it previously or trust it at all.
4382 Affected file silcd/protocol.c.
4384 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4386 * Check in the silc_server_timeout_remote if protocol is active
4387 and make sure that the protocol's final callback is called so
4388 that all memory if freed. Affected file silcd/server.c.
4390 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4392 * silc_server_whois_send_reply crashed the server if the nickname
4393 was 127 characters long. Affected file silcd/command.c.
4395 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4397 * Added sanity check to the silc_server_new_client. If the hostname
4398 is provided inside username then check that the provided hostname
4399 really is the same as the resolved one. If the hostname was not
4400 resolved then check it from the public key. Affected file is
4401 silcd/packet_receive.c.
4403 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
4404 if the server disconnected us and the connection is not valid
4405 anymore. Affected file irssi/src/silc/core/silc-channels.c.
4407 * Moved the silc_client_[chmode|chumode|chumode_char] away from
4408 the library to the lib/silcutil/silcutil.[ch].
4410 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4412 * Close log file after open. Affected file
4413 lib/silcutil/silclog.c.
4415 * Check whether sock == NULL in silc_client_send_packet and return
4416 if it is. Affected file lib/silcclient/silcclient.c.
4418 * Check rec->entry == NULL in the Irssi SILC Client before
4419 sending the channel message. Affecte file is
4420 irssi/src/silc/core/silc-servers.c.
4422 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4424 * Merged a splitted window bugfix from Irssi CVS tree. The
4425 affected file is irssi/src/fe-text/textbuffer-view.c.
4427 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
4428 It did not print nickname.
4430 * Improved the distributions system a bit.
4432 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4434 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
4435 irssi/src/fe-text/gui-window.c.
4437 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
4438 to in-active server. The affected file is
4439 irssi/src/silc/core/client_ops.c.
4441 * Resolve the client in USERS command reply if the entry does
4442 not have username resolved. The affected file is
4443 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
4444 command to WHOIS command to really resolve stuff. The USERS
4445 is not used any more in any critical section so WHOIS can
4446 be used even though it might be slower than IDENTIFY.
4448 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
4451 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4453 * Changed the protocol API a bit more consistent in the
4454 lib/silccore/silcprotocol.[ch].
4456 * Changed the following headers to ROBODoc format:
4458 lib/silccore/silcpayload.h
4459 lib/silccore/silcprotocol.h
4460 lib/silccore/silcsockconn.h
4462 All core library headers are now formatted.
4464 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4466 * Fixed a bug in Irssi SILC client; do not show that you are
4467 server/router operator if you really are not. Affected file is
4468 irssi/src/silc/core/client_ops.c.
4470 * Renamed silc_command_free_payload to silc_command_payload_free.
4471 Affected file lib/silccore/silccommand.h
4473 * Added silcmath.h to include the prototoypes of various routines
4474 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
4477 * Changed the following headers to ROBODoc format:
4479 lib/silccore/silcchannel.h
4480 lib/silccore/silccommand.h
4481 lib/silccore/silcid.h
4482 lib/silccore/silcidcache.h
4483 lib/silccore/silcmode.h
4484 lib/silccore/silcnotify.h
4485 lib/silccore/silcpacket.h
4486 lib/silcmath/silcmath.h
4488 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4490 * Added checking to the server code not to start the server if
4491 ciphers and stuff are not configured properly. Affected files
4492 silcd/serverconfig.[h] and silcd/server.c.
4494 * Changed the layout of the header files of the public interfaces
4495 in the SILC libraries. The new layout supports ROBODoc
4496 documentation tool (and some others) so that it is easy to create
4497 a library reference manual. All the other headers and source
4498 code must still follow the CodingStyle document. Also source
4499 code must not include these ROBODoc stuffs, only the headers.
4500 Furthermore, all public interface headers must now be named
4501 by using `silc' prefix, example: silcapi.h, silccipher.h.
4502 Some files were renamed due to this. All the other headers
4503 must not be used as public interfaces. I will update the
4504 CodingStyle document later. Changed following headers, so far:
4506 lib/silcclient/silcapi.h
4507 lib/silccore/silcauth.h
4508 lib/silccore/silcprivate.h
4509 lib/silccrypt/silcdh.h
4511 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4515 * Removed silc_client_packet_send_flush from the client library
4516 as it is not needed. Affected file lib/silcclient/client.[ch].
4518 * Added printing of message of unresolved authentication method
4519 to the Irssi SILC client. Added it to the module formats.
4520 Removed the same message from the client library.
4522 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4524 * Added new distribution feature, DISTLABEL. Every distribution
4525 can define own preprocessor label that can be used in the
4526 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
4527 file distributions, acconfig.h.pre and prepare.
4529 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4531 * Added Makefile.defines_int to include the actual definitions
4532 for Makefile.defines.in. Tested the new distribution system,
4533 created distributions and tested installation.
4535 * Added AWAY message printing to the Irssi SILC client. Added
4536 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
4538 * Added SCONNECT command to call the SILC's CONNECT command.
4539 Cannot use CONNECT directly since Irssi uses that internally.
4540 Affected file irssi/src/silc/core/silc-servers.c.
4542 Added ACTION local command. It is same as ME command but takes
4543 the channel as mandatory argument.
4545 Rewrote some of the Irssi's help files to suite for SILC
4548 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4550 * Added Makefile.defines[.in] that should for now on be included
4551 in all Makefile.am file in the source tree. That file includes
4552 all common compilation definitions for SILC source tree.
4554 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4556 * Minor changes to the ./prepare script to change the package
4557 name according the distribution name to the configure.in.
4559 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4561 * Created new distribution system. Added file `distributions'
4562 that defines all the distributions that can be created out of
4563 the SILC source tree. The ./prepare script now reads that
4564 file to determine how to prepare the distributions. The
4565 first argument to the ./prepare is the name of the distribution
4566 and second is the version of the distribution. If given
4567 without arguments it creates the default (toolkit) distribution
4568 with the default version (defined in ./prepare).
4570 All Makefile.am files that are subject to the distributions
4571 are now named as Makefile.am.pre. These are ./Makefile.am
4572 and lib/Makefile.am. Others may be changed later.
4574 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4576 * Added invite list, ban list, some key management and connection
4577 error message printing to module formats in the Irssi SILC client.
4579 * Added new silc_client_set_away_message to set the away message
4580 that is back to the person who sent private message. The
4581 affected file lib/silcclient/silcapi.h and the
4582 lib/silcclient/client_prvmsg.c.
4584 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4586 * Fixed the private message sending in the Irssi SILC client,
4587 added local command KEY to the Irssi SILC client.
4589 Added key management and key agreement message formats to the
4590 irssi/src/fe-common/silc/module-formats.[ch].
4592 Added USERS (alias WHO) printing, server/router operator
4593 indication and LIST command printing to the module formats.
4595 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4597 * Fixed channel joining notify handling, cumode notify handling
4598 from Irssi SILC client.
4600 * Added SILC specific module-formats to the Irssi SILC client so
4601 that SILC specific message hilighting, colors etc is possible.
4602 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4604 Added channel mode, channel user mode, actions, notices,
4605 whois and whowas printing to the the module-formats.c.
4607 * Fixed a bug in channel deletion in the server. The channel
4608 is not left to the cache even if the channel founder auth mode
4609 is set when there are no users anymore on the channel. Affected
4610 file silcd/server.c.
4612 * The silc_net_localhost now resolves the entire hostname including
4613 the domain name. Affected file lib/silcutil/silcnet.c.
4615 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4617 * Changed the ask_passphrase client operation to be ascynchronous.
4618 It has now a completion callback and a context that the
4619 application must call after it has got the passphrase from
4620 the user. Affected files lib/silcclient/silcapi.h,
4621 lib/silcclient/protocol.c, lib/silcclient/command.c and
4624 Added SilcAskPassphrase callback that the application calls
4625 to deliver the passphrase to the library.
4627 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4628 The public key verification and especially a certificate
4629 verification is asynchronous procedure.
4631 Added new SILC_SKE_STATUS_PENDING status to indicate the
4632 request is pending and a callback will be called to finalize
4635 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4636 indicate that remote end did not send its public key (or
4637 certificate), even though we require it. Added check for this
4638 condition in the SKE. This was a security bug, now fixed.
4640 Defined new SilcSKEVerifyCbCompletion callback that is called
4641 when the verification process is completed.
4643 The affected files lib/silcske/silcske_status.h and
4644 lib/silcske/silcske.[ch].
4646 * Changed the verify_public_key client operation to be async
4647 as well. Defined SilcVerifyPublicKey callback that is used to
4648 indicate the success of the public key verification process.
4650 Changed the server and client to use the new async client
4653 * Changed the Irssi SILC client's internal scheduler to be called
4654 twice as many times as it used to be. As a result the client
4655 should be a bit faster now. Affected file is
4656 irssi/src/silc/core/silc-core.c.
4658 * Added support to Irssi SILC client of asynchronous public key
4659 verification and passphrase inquiry. Affected file is
4660 irssi/src/silc/core/silc-core.c.
4662 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4664 * Do not say "You have left channel %s" in client library.
4665 Moved it to the application. Affected files are
4666 lib/silcclient/command.c and silc/client_ops.c.
4668 * Fixed silc_client_get_clients. Command context was not
4669 duplicated and was freed memory in the callback. Affected
4670 file lib/silcclient/idlist.c.
4672 * Do not say "you are now talking..." on JOIN command in the
4673 client library. The appliation must handle it.
4675 * Do not say ".. changed topic to" in command reply in the
4676 client libary. The application must handle it.
4678 * Fixed TOPIC command sending in the client library.
4680 * Fixed a memory leak in silc_client_command_free in the file
4681 lib/silcclient/command.c.
4683 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4685 * Imported a modified version of Irssi client to the source tree.
4686 The Irssi will be used to create a new client called
4687 Irssi SILC. Imported to irssi/.
4689 Added silc_core_init_finish function to the Irssi. Affected
4690 file irssi/configure.in.
4692 A lot changes in the Makefile.ams around the irssi tree.
4694 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4696 * Do not rehash if the new size is same as the old size of the
4697 hash table, in the silc_hash_table_rehash*. The affected file
4698 lib/silcutil/silchashtable.c.
4700 * Replaced hash_table_del_by_context calls from the server
4701 (when channel->user_list and client->channels) to the
4702 hash_table_del as it is sufficient and faster.
4704 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4706 * Added silc_hash_table_list, silc_hash_table_get and the
4707 SilcHashTableList structure to provide an alternative way to
4708 traverse the hash table. The affected files are
4709 lib/silcutil/silchashtable.[ch].
4711 * Changed the server's idlist routines to use the hash table
4712 routines to optimize the code.
4714 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4716 * Replaced the client entry's `channel' list and channel entry's
4717 `user_list' list to hash tables for optimized lookup. Changed
4718 the code to use the hash table interface around the code.
4719 Affected file lib/silcd/idlist.[ch].
4721 * Added `auto_rehash' boolean argument to the function
4722 silc_hash_table_alloc to indicate whether the hash table should
4723 auto-rehash when it thinks is appropriate time. It will
4724 increase the hash table size if the there is twice as much
4725 entries in the table than the size of the table, and will
4726 decrease the size if there are twice as less entries than
4727 the size of the table.
4729 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4731 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4733 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4735 * silc_idcache_purge_by_context deletes the entry now by context
4736 as it is supposed to do. Affected file lib/silccore/idcache.c.
4738 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4739 client is not anymore valid (WHOWAS givens the info) and not
4740 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4742 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4744 * Removed the `data' and `data_len' arguments from the ID Cache
4745 interfaces and added `name' argument. ID Cache does not handle
4746 anymore the binary data only a names associated with given ID.
4748 * When hashing a Client ID with silc_hash_id the entire ID is
4749 not hashed anymore, instead only the hash of the Client ID is
4750 hashed. This way we can access the Client ID from the cache
4751 with Client ID but with the hash of the ID (which is a hash of
4752 the nickname) as well without any difference in performance.
4754 Added also silc_idcache_find_by_id_one_ext to do one on one
4755 searching when we have the actual ID. Added also function
4756 silc_hash_client_id_compare. The affected files are
4757 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4759 * When hashing the name associated with a ID it is always done
4760 in lowercase. This way we can access the cache without worrying
4761 about case-sensitivity, even though, for example nicknames are
4764 * Fixed a bug in server with channel message sending. It put
4765 wrong ID type as destination ID. The affected file
4766 silcd/packet_send.c.
4768 * silc_idcache_del_by_context now deletes from all hash tables
4769 by context. Affected file lib/silccore/idcache.c.
4771 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4773 * Changed the client library to use the new ID Cache interface.
4774 Changes around the source tree.
4776 * Added silc_hash_table_rehash_ext to rehash with specific
4777 hash function. Affected file lib/silcutil/silchashtable.[ch].
4779 * Added silc_hash_string_compare to compare two strings in the
4780 hash table. Affected file lib/silcutil/silcutil.[ch].
4782 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4784 * Added new function silc_idcache_del_by_context into the
4785 lib/silccore/idcache.[ch].
4787 * Changed the server's ID list routines to use the new ID Cache
4788 interface. Changes around the source tree.
4790 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4792 * Added silc_hash_table_del[_by_context]_ext functions in to the
4793 lib/silcutil/silchashtable.[ch].
4795 Removed silc_hash_table_find_all* routines and added new
4796 silc_hash_table_find_foreach to replace them.
4798 Added silc_hash_table_replace_ext function as extended
4799 replacing function. Separated the simple hash table interface
4800 from the extended hash table interface in the file
4801 lib/silcutil/silchashtable.h.
4803 * Fixed minor bugs and changed it to use some of the new
4804 hash table functions in lib/silccore/idcache.c
4806 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4808 * Added new function silc_hash_table_find_all to return all keys
4809 in the hash table by the specified key. As the hash table is
4810 collision resistant it also makes it possible to have several
4811 duplicate keys in the hash table. This function may be used to
4812 find all of the keys from the hash.
4814 Added user_context arguments to the SilcHashFunction,
4815 SilcHashCompare and SilcHashDestructor to deliver user specified
4818 Added new fuctions silc_hash_table_find[_all]_ext to do
4819 extended lookup with specified hash and compare functions and
4820 specified user contexts.
4822 Added new function silc_hash_table_add_ext to add the key
4823 with specified hash function and user context.
4825 Added new function silc_hash_table_foreach to traverse all
4826 entrys in the hash table. Added SilcHashForeach callback
4829 Added new function silc_hash_table_del_by_context to delete
4830 the entry only if the context associated with the key matches.
4832 Affected files are lib/silcutil/silchashtable.[ch].
4834 * Removed silc_hash_[server/client/channel]_id and added just
4835 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4836 silc_hash_id_compare to compare two ID's using as the hash table
4837 comparison function. Added also silc_hash_data to hash
4838 binary data and silc_hash_data_compare to compare it.
4840 * Removed silc_idlist_find_client_by_hash as it is not needed
4841 anymore. Affected file silcd/idlist.[ch].
4843 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4844 to use internally the SilcHashTable. The new ID Cache is a lot
4845 faster than the old one. Some of the ID Cache interface was also
4846 rewritten and obsolete and stupid functions were removed.
4848 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4850 * Added entry_count field to the SilcHashTable to keep the number
4851 of the entries in the table. Implemented the function
4852 silc_hash_table_rehash. Added new function
4853 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4855 Fixed a minor bug in silc_hash_table_free.
4857 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4858 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4859 into the lib/silcutil/silcutil.[ch].
4861 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4863 * Implemented a collision resistant hash table into the
4864 lib/silcutil/silchashtable[ch]. See the header and the source
4865 for the SilcHashTable API.
4867 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4869 * Merged dotconf version 1.0.2 into lib/dotconf.
4871 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4873 * Do not compile anything in lib/silcsim/* if the SIM support
4874 is not enabled. The tree should now compile without problems
4877 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4879 * Compiled the SILC under cygwin. Compiled and tested briefly
4880 without problems. More tests needed. The SIMs didn't compile
4883 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4885 * Fixed possible crash in silc_get_username in the
4886 lib/silcutil/silcutil.c.
4888 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4890 * Fixed a va_arg in silc/client_ops.c.
4892 * Oops, RC5 routines were named AES and caused some problems
4893 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4895 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4897 * Added new SilcIDIP structure into the lib/silccore/id.h and
4898 replaced the old `ip' fields from all SILC ID's to that type.
4899 This is a step towards IPv6 support.
4901 The silc_id_get_len takes now the ID as an extra argument.
4902 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4903 both IPv4 and IPv6 based ID's.
4905 The affected files are lib/silccore/id.[ch] and other files
4906 around the tree using these routines.
4908 * Removed the ID length arguments in server from various
4909 silc_server_send_notify_* routines -> they are not needed
4912 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4914 * Fixed memory leak in silc_encode_pem_file in the file
4915 lib/silcutil/silcutil.c.
4917 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4919 * Check minor version as well in the SKE. Affected files are
4920 silcd/protocol.c and lib/silcclient/protocol.c.
4922 * Added --identifier option to the server so that an identifier
4923 can be when creating the public key for the server. Affected
4924 file is silcd/silcd.c.
4926 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4927 lib/silccrypt/silcpkcs.c.
4929 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4931 * Register default ciphers and stuff when using -C option with
4932 the server. Affected file sildc/silcd.c.
4934 * Put back the servers public key filename format, it is better
4935 than the new one. For now, the client keys are saved with the
4936 new filename format. The affected file silc/client_ops.c.
4938 * Implemented the Cipher API for the rest of the ciphers that
4939 did not implement it or implemented it the wrong way.
4941 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4943 * Register default ciphers and stuff when using the -S option
4944 in the client. Affected file silc/silc.c. Same also when
4945 creating new key pair with -C option.
4947 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4949 * Fixed the silc_verify_public_key client operation function to
4950 save the public keys differently. The fingerprint is now
4951 used as filename and not the hostname. This way also the
4952 client keys are saved uniquely and not with hostnames. The
4953 affected file is silc/client_ops.c.
4955 * Trimmed the silc_hash_fingerprint function to remove extra
4956 whitespaces from the end of the fingerprint. The affected
4957 file is lib/silccrypt/silchash.c.
4961 * Added silc_cipher_register_default function to register all
4962 default ciphers. It can be used when configuration files
4963 does not exist and the application does not want any specific
4964 ciphers in any specific order.
4966 The SilcDList is now used as silc_cipher_list dynamically
4967 allocated cipher list. Removed the static list all together
4968 and now all ciphers must be allocated to the dynamic list.
4969 The silc_cipher_alloc routine was changed to check only the
4972 All silc_cipher_* routines that used to return int returns
4975 The affected files lib/silccrypt/silccrypt.[ch].
4977 * The same thing was done to silc_hash_* as for silc_cipher_*
4978 routines. Affected files lib/silccrypt/silchash.[ch].
4980 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4981 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4982 Added also silc_pkcs_[un]register[_default] functions.
4983 Removed the data_context from the PKCS API.
4985 * Added silc_hmac_register_default function to register default
4986 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4987 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4988 to unregister all hmacs at once.
4990 * Register the default ciphers, hash functions, PKCSs and HMACs
4991 if client's configuration file does not exist. The affected
4994 * The client did not load the hash functions from the SIM
4995 modules at all. Added support for this. Affected file is
4996 silc/clientconfig.c.
4998 * When decoding public key with silc_pkcs_public_key_decode, check
4999 the supported algorithm only if PKCS are registered. Affected
5000 file lib/silccrypt/silcpkcs.c. The same was done with the
5001 silc_pkcs_private_key_decode.
5003 * Fixed the SILC List routines to keep the list always in order.
5004 It used to change the list's order when traversing the list but
5005 not it preserves the order. Affected file lib/trq/silclist.h.
5007 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5009 * Added the client library to use the SilcSocketConnection's
5010 reference counter (by silc_socket_dup) to prevent the bug that
5011 the socket object may be freed underneath async operation.
5013 * The name resolv library checking fixes in the configure.in.pre.
5016 * Created new version of the protocol drafts for future
5017 development. The -03 drafts are the ones that will be changed
5018 in the trunk now and the -02 will remain as they are.
5020 * Send list of CUMODE notifys to the router when announcing
5021 the channel users to the router. Affected file silcd/server.c.
5022 If the router receiving channel founder CUMODE for a channel
5023 that already has channel founder it will send CUMODE notify
5024 to the sender to remove the channel founder rights from the
5025 announced client. Affected file silcd/packet_receive.c.
5027 * The CUMODE notify may now use Server ID as well as the entity
5028 who changes the mode. Updated protocool specs.
5030 * Updated INSTALL and README files.
5032 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5034 * New web pages in the http://silc.pspt.fi. The pages was
5039 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5041 * Implemented the [DenyConnectin] config section in the server.
5042 Added silc_server_config_denied_conn to check whether incoming
5043 connection is denied. Affected file silcd/serverconfig.[ch].
5045 * Do not check the ports when checking the incoming configuration
5046 data if the port is 0, meaning any. Affected file is
5047 silcd/serverconfig.c.
5049 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5051 * Fixed buffer overflow in silc_string_compare in the file
5052 lib/silcutil/silcutil.c.
5054 * Fixed double free in silc_server_command_leave in the file
5057 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5059 * Fixed the version checking in the server. Affected file is
5062 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5064 * Fixed the configuration data fetching when accepting new
5065 connections in the server. Affected file silcd/server.c.
5067 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5069 * Added `sender_entry' argument to the function
5070 silc_server_packet_relay_to_channel so that we can check
5071 whether some destination actually belongs to the same route
5072 the sender belongs (ie, we must not resend the packet to the
5073 sender). Affected file silcd/packet_send.[ch].
5075 * Added `servername' field to the SilcClientEntry in the server
5076 to hold the name of the server where client is from. Affected
5077 file is silcd/idlist.h.
5079 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5081 * Moved the channel message encrypting in the router betwen
5082 router connections from silc_server_channel_message to the
5083 silc_server_packet_relay_to_channel since we want to check
5084 whether we have anybody channel before encrypting anything.
5085 Affected files silcd/packet_[receive/send].c.
5087 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5089 * Fixed the [AdminConnection] server config section to support
5090 multiple entries. Affected file silcd/serverconfig.c.
5092 * Added support into the server to check the validity of the
5093 incoming connection before executing any KE or authentication
5096 * The connection configuration is now saved to the KE and
5097 connection auth protocol contexts and not fetched anymore in
5098 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
5100 * The local hosts listenning address and port is also resolved
5101 now when starting the server. We want to have the socket object
5102 to include the real address and port for the listener. Added
5103 new function silc_net_check_local_by_sock into the files
5104 lib/silcutil/silcnet.[ch].
5106 * Fixed a broadcast bug in server -> do not broadcast if we
5109 * Fixed a routing bug. Do not route broadcast packets ever.
5110 Broadcast packets must be processed always and not routed since
5111 they may be destined to some other host than yourself and thus
5112 would get routed without no good reason. Affected file is
5115 * Added function silc_server_config_is_primary_route to check
5116 whether primary router connection has been configured (a router
5117 configuration that we are initiating). If there is not, we
5118 will assume that there is only two routers in the SILC network
5119 and we will use the incoming router connection as our primary
5120 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
5122 * Changed the order of the broadcasting. Broadcast _after_ the
5123 packet has been processed not before. Affected file is
5126 * Fixed a [ClientConnection] parsing bug. The port was never
5127 parsed correctly thus resulting to port 0. Affected file
5128 silcd/serverconfig.c.
5130 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
5131 argument and did not set the broadcast packet flag. Affected
5132 file silcd/packet_send.c. Fixed same bug in the function
5133 silc_server_send_notify as well.
5135 * If we receive NEW_ID packet for our own ID in the server, ignore
5138 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5142 * Removed the nickname from the Private Message Payload.
5143 Updated the code and the protocol specs.
5145 * Updated protocol specs for submitting to the IETF.
5147 * Tweaked the Random Number Generator a bit. Affected file
5148 lib/silccrypt/silcrng.c. Exported a new function
5149 silc_rng_[global]_add_noise which can be used to add more
5152 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5154 * Do not parse packets with different timeout when protocol
5155 is active -> may cause problem with rekey. Affected file
5158 * When server receives signoff notify it must not create
5159 new channel key if the client is on any channels since the
5160 sender of the signoff notify will create it.
5162 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5164 * Added printing of error messages during SKE protocol from the
5165 failure packet sent by server during SKE. Affected file
5168 * Removed the client's failure_callback handling with timeout
5169 and handle it immediately when received.
5171 * The SKE library returned wrong type in SUCCESS and FAILURE
5172 packets. They must be 32 bit MSB not 16 bit MSB.
5174 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5176 * Ok, rewrote the logic of the re-key and now it seems to work.
5177 I tested it on high traffic with frequent re-keys without
5178 problems. Added hmac_receive (and renamed hmac to hmac_send)
5179 in SilcClientConnection in lib/silcclient/client.h and
5180 in SilcIDListData in silcd/idlist.h. Also, removed the
5181 SilcPacketParserContext's cipher and hmac fields as they are
5182 not needed anymore and actually caused some problems when
5183 the ciphers and hmac's changed underneath the packet parser.
5185 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5187 * If re-key protocol is active then process the incoming packets
5188 synchronously since we must assure that icoming packets encrypted
5189 with the old key is processed before the new keys is set to
5190 use. This is true other packets than for REKEY packets.
5191 Affected file silcd/server.c. The same was done to client library
5192 as well, affected file lib/silcclient/client.c.
5194 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5196 * Fixed bug in client and server to accept the force send if
5197 the packet is send from silc_[server/client]_packet_process
5198 function. Otherwise the packets are never delivered, oops.
5200 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5202 * Disable force sending of packets when REKEY protocol is active.
5203 We must assure that no packet is sent directly when rekey is
5204 performed. All packets must be sent through packet queue.
5205 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
5206 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
5207 function is silc_[server/client]_packet_send_real to check
5210 * Replaced the SIM paths from example config files to
5211 /usr/local/modules. Also, make install creates now
5212 /usr/local/silc/logs directory to hold all the SILC server
5215 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5217 * Made the configure.in.pre work on Solaris. Patch by salo.
5219 * Made all ciphers compatible with non-x86 machines. Defined
5220 CBC mode macros into lib/silccrypt/ciphers_def.h.

5226 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5228 * When MAC computation fails the silc_packet_decrypt returned 0
5229 even though it was supposed to return -1. Fixed this. The
5230 affected file is lib/silccore/silcpacket.c.
5232 * Do not replace the config files in /etc/silc (in make install)
5233 if they already exist. Affected file ./Makefile.am.
5235 * Do not send re-key packets immediately but through packet queue.
5236 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
5238 * Changed silc_net_check_host_by_sock to return FALSE if the
5239 IP/DNS could not be resolved. Though, it returns the IP address
5240 now even if it could not resolve it (but returns also FALSE).
5241 Affected file lib/silcutil/silcnet.[ch].
5243 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5245 * Added silc_pkcs_decode_identifier to decode the public key's
5246 identifier. Affected file lib/silccrypt/silpkcs.[ch].
5247 Added also silc_pkcs_free_identifier. Added also new context
5248 SilcPublicKeyIdentifier.
5250 * Added -S option to the silc client. It is used to dump the
5251 contents of the specified public key file.
5253 * Changed the PKCS api to return the public key length when
5254 setting the public key.
5256 * Fixed a fatal bug in the public and private key file loading.
5257 Affected file lib/silccrypt/silcpkcs.c.
5259 * Execute the packet parsing for client with zero (0) timeout
5260 if the protocol is active. Affected file silcd/server.c.
5262 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5264 * Made the key generation options to the silcd program. Added
5265 -C option, equivalent to client's option.
5267 * Added new [ServerKeys] config section to the server. It
5268 configures the server's public and private key.
5270 * Defined generic Public Key Payload into the protocol
5271 specification to send specific type of public keys and
5274 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
5275 public key or certificate.
5277 * Implemented the GETKEY command to the server and to the
5278 client library and on user interface.
5280 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5282 * Made preliminary `make install' work.
5284 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5286 * Added SilcServerRekey context into silcd/idlist.h.
5288 * Added the PFS support as defined in the specification to the
5289 SKE protocol. Affected files lib/silcske/*.c.
5291 * Added `ske_group' field to the SilcServerRekey context to hold
5292 the number of the SKE group that is used with PFS in re-key.
5293 Affected file silcd/idlist.h.
5295 * Added PFS re-key support to the server. Affected file is
5298 * Added silc_protocol_cancel to cancel execution of the next
5299 state of the protocol. Affected file is
5300 lib/silccore/silcprotocol.[ch].
5302 * Added the re-key support with and without PFS to the client
5303 library. Re-key is performed once in an hour, by default.
5305 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
5306 Added silc_client_rekey_callback and silc_client_rekey_final.
5307 Affected files are lib/silcclient/protocol.[ch] and
5308 lib/silcclient/client.[ch].
5310 * Removed the `hmac_key' and `hmac_key_len' fields from the
5311 SilcClientConnection structure; not needed. Affected file is
5312 lib/silcclient/client.h.
5316 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5318 * Do not ask whether user wants to use the negotiated private key
5319 for private messages, just use it. Affected file is
5320 silc/local_command.c.
5322 * Added `send_enc_key' and `enc_key_len' fields to the
5323 SilcIDListData structure since they are needed in the re-key
5324 phase. Affected file is silcd/idlist.[ch].
5326 * Implemented the simple re-key protocol into the server.
5327 Affected files silcd/server.c and silcd/protocol.[ch]. The
5328 re-key will be performed once in an hour, by default.
5330 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
5331 Added silc_server_rekey, silc_server_rekey_callback and
5332 silc_server_rekey_final.
5334 * Removed Tunneled flag from the protocol. Updated the code
5335 and the specifications.
5337 * Adde `pfs' field to the SilcIDListData to indicate whether
5338 the PFS is to be performed in the re-key. Affected file is
5341 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5343 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
5344 int64 of at least the xintXX size. If void * is less that 4
5345 bytes uint32 * will be used. Defined bool as boolean.
5347 * Changed _ALL_ unsigned long and unsigned int to uint32,
5348 unsgined short to uint16 in the source tree.
5350 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
5351 not handle clients that has entry->data.registered == FALSE.
5352 They are not in the network anymore. Affected file is
5355 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5357 * Implemented the sending of the SERVER_SIGNOFF notify in the
5358 server. Affected file is silcd/server.c.
5360 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
5361 Added also silc_notify_payload_encode_args into the
5362 lib/silccore/silcnotify.[ch].
5364 * Implemented ther SERVER_SIGNOFF notify handling in the server.
5365 Affected file silcd/packet_receive.c.
5367 * Implemented the SERVER_SIGNOFF notify handling in the client
5368 library. Affected file lib/silcclient/client_notify.c. Also,
5369 implemnted the printing of the SERVER_SIGNOFF info to the
5370 application. Affected file silc/client_ops.c.
5372 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
5373 if the deleting was successful. Affected file silcd/idlist.[ch].
5375 * Added support for public key authentication in the connection
5376 authentication protocol in the client library. Affected file
5377 lib/silcclient/protocol.c.
5379 * Changed the server's silc_idlist_get_clients_by_* interface
5380 to support already allocated array so that new entries may be
5381 added to pre-allocated array. Affected file silcd/idlist.[ch].
5382 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
5383 and command replies.
5385 * All command reply functions in the server now calls the
5386 pending command callback even if error occured. This way the
5387 error will be delivered to the client as well. Affected files
5388 silcd/command.c and silcd/command_reply.c.
5390 * Fixed INFO command to return local server's info if no server
5391 was provided. Affected file lib/silcclient/command.c.
5393 * Removed RESTART command for good. Updated the code and the
5396 * Rewrote parts of the task system. It is a bit simpler now.
5397 Removed unsued task priorities. The affected files are
5398 lib/silcutil/silctask.[ch].
5400 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5402 * Moved the USERS printing from the library to the application.
5403 Affected files lib/silcclient/command.c and silc/client_ops.c.
5405 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5409 * Added channel key re-key support. The re-key is perfomed
5410 only by the router and is done once in an hour. Added `rekey'
5411 field to the SilcChannelEntry in the server. Affected files
5412 silcd/server.c and silcd/idlist.h.
5414 * Added silc_task_unregister_by_context into the file
5415 lib/silcutil/silctask.[ch].
5417 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5419 * Added SILC_UMODE_GONE mode to indicate when the client is not
5420 present in the SILC network. Added also support to the local
5421 command AWAY that will set this mode. Added support of showing
5422 "xxx is gone" in WHOIS command. The USERS command shows the
5423 gone status as well.
5425 * Fixed setting server and router operator privileges in the
5426 server's UMODE command. Affected file silcd/command.c.
5428 * Merged the SKE KE1 and KE2 payloads into one payload. The
5429 new KE payload is equivalent to the old KE2 payload.
5431 Cleaned up the SKE Start Payload parsing. It now uses the
5432 simple buffer unformatting to do the parsing. A lot faster
5435 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
5436 to the SKE that is used to indicate whether both of the SKE
5437 parties should perform authentication. By default only the
5438 responder performs authentication. By setting this flag also
5439 the initiator must do authentication. By default it is unset
5440 since in normal SKE case, client to server connection, only
5441 the responder should do authentication. When doing SKE between
5442 two clients both should perform authentication. Updated the
5443 code and the protocol specs.
5445 * A little fix to IDENTIFY command in the server. Search the
5446 client first by hash not nickname. Affected file is
5449 * Fixed the silc_client_close_connection to support closing
5450 the client to client connections wihtout deleting too much
5451 data. Affected file lib/silcclient/client.c.
5453 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
5454 are received if protocol used to be active but is not anymore
5455 the application would crash due to NULL pointer dereference.
5456 Affected files silcd/server.c and lib/silcclient/client.c.
5458 * Added `hash' field to the SilcClientConnection to include
5459 the hash function negotiated in the SKE protocol.
5461 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
5462 to set the channel founder authentication data. A client can
5463 claim the founder rights later by providing the authentication
5464 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
5465 This way the channel founder can regain the channel founder
5466 privileges even it is left the channel. This works only on
5467 local server and the client must be connected to the same
5468 server to be able to regain the founder rights. Updated the
5469 protocol specs accordingly.
5471 Added support to the CMODE command in the client to set the
5472 founder auth data. Read the README to see how to set it.
5474 Added support to the CUMODE command to claim the founder
5475 rights. Read the README to see how to do it.
5477 Added support for the founder authentication to the Channel
5478 Entry in the server. Affected file silcd/idlist.h.
5480 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
5481 server's CMODE command. Affected file silcd/command.c.
5483 * Added the following new functions into lib/silccore/silcauth.[ch]:
5484 silc_auth_get_method and silc_auth_get_data.
5486 * The server now saves the remote hosts public key to the
5487 SilcIDListData pointer. Affected file silcd/protocol.c.
5489 * The normal server now does not remove the channel entry from
5490 the cache if the founder authentication data is set. It used
5491 to remove it if the founder was the last one on the channel on
5492 the server and left the channel. The auth data is saved and
5493 if the channel is re-joined later the old entry is used with
5494 the old auth data. Affected files silcd/command_reply.c and
5497 * Removed the `pkcs' field from the SilcIDListData structure
5498 in the server; it is not used. Affected file silcd/idlist.h.
5500 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5502 * Fixed packet processing on slow links. Partial packets were
5503 never re-processed because the incoming data buffer was cleared
5504 by the application. Application must not directly clear the
5505 sock->inbuf, the packet processing routines handle it. Fixed
5506 this in client library and in server.
5508 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5510 * Fixed the WHOIS and IDENTIFY send reply function to really
5511 check whether to send list or just one entry. Affected file
5514 * Cleaned up the LEAVE command's channel key distribution. The
5515 affected file silcd/command.c.
5517 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
5518 can enforce the channel mode as well. In that case the ID
5519 includes the ID of the server. The code now enforces the
5520 mode change if the router have different mode than the server.
5522 * The notify client operation with CMODE_CHANGE notify can now
5523 return NULL client_entry pointer if the CMODE was not changed
5524 by client. Application must check for this.
5526 * Added <Server ID> argument to INFO command to support server
5527 info fetching by Server ID.
5529 * Added silc_server_announce_get_channel_users to get assembled
5530 packets of channel users of the specified channel. Affected
5531 file silcd/server.[ch].
5533 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
5534 was freed underneath the ID Cache.
5536 * Re-announce clients when the server received CHANNEL_CHANGE
5537 notify from the router. Affected file silcd/packet_send.c.
5539 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5541 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
5542 crashed since it did not handle the fact that there is no cipher
5543 called "3" and didn't check the error condition. Now fixed.
5545 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
5546 flag. It can be used to send message requests.
5548 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5550 * Implemented the RESTART command in the client.
5552 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
5553 notice type messages. Added notice printing to the user
5556 * The channel keys are not re-generated if the channel's mode
5557 is PRIVKEY, ie private key on the channel exists. Affected
5558 files silcd/server.c and silcd/command.c.
5560 * Fixed a little bug in channel message delivery when channel
5561 private keys are set in the server. Affected file is
5562 silcd/packet_send.c.
5564 * Changed the setting on channel->on_channel = TRUE from the
5565 silc_client_save_channel_key to the JOIN command reply. The
5566 key payload is not received if the private channel key is set.
5567 Affected file lib/silcclient/command_reply.c and the
5568 lib/silcclient/client_channel.c.
5570 * When the CMODE_CHANGE notify is sent and the channel private
5571 key mode is removed the channel key must be re-generated in
5572 other cells as well. Added this support for the router in the
5573 silcd/packet_receive.c.
5575 * Added new local command NOTICE to send notice message on
5576 channel. Affected file silc/local_command.[ch].
5578 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5580 * Added new local command ME to the client. It is used to send
5581 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
5582 some action. Affected file silc/local_command.[ch].
5584 * Changed channel_message and private_message client operations
5585 to deliver the message flags to the application. Added also
5586 the `flags' arguments to the silc_client_send_channel_message
5587 and silc_client_send_private_message functions. Affected file
5590 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5592 * Redefined the Private Message Payload to support private message
5593 keys and to support the new private message flags. Updated
5594 the protocol specs. Flags makes it possible to have for example
5595 CTCP style messages.
5597 * Added new type SilcPrivateMessagePayload and defined an API
5598 for it in the lib/silcclient/silcprivate.[ch].
5600 * Tested private message private keys successfully. Tested the
5601 private message key set, unset and list commands with the new
5604 * Redefined the Channel Message Payload to include the channel
5605 message flags (equal with private message flags) to support
5606 for example CTCP style messages.
5608 * Defined some of the message (for channel and private message)
5609 flags. Updated the protocol specs and added the flags to the
5610 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5612 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5614 * Added SilcKeyAgreementStatus type to the key agreement routines
5615 to indicate the current status and error if one occured.
5616 The status types are defined in the lib/silcclient/silcapi.h.
5618 * Added new local command KEY that is used to set and unset private
5619 keys for channels, set and unset private keys for private messages
5620 with remote clients and to send key agreement requests and
5621 negotiate the key agreement protocol with remote client. The
5622 key agreement is supported only to negotiate private message keys,
5623 it currently cannot be used to negotiate private keys for channels,
5624 as it is not convenient for that purpose.
5626 * Fixed a minor pending callback setting bug in the function
5627 silc_client_get_client_by_id_resolve, now the function works.
5628 Affected file lib/silcclient/idlist.c.
5630 * Added function silc_net_get_local_port to get local bound
5631 port by socket. Added to lib/silcutil/silcnet.[ch].
5633 * Added `sockets' and `sockets_count' fields to the SilcClient
5634 object. They hold the sockets of the listenning sockets in
5635 the client. Listenning sockets may be for example the key
5636 agreement server. Affected file lib/silcclient/client.[ch].
5637 Added functions the silc_client_add_socket and the
5638 silc_client_del_socket. They are exported to the application
5641 * Added ~./silc/clientkeys to support other client's public keys.
5643 * Renamed verify_server_key client operation to verify_public_key
5644 and added one argument to indicate the type of the connection
5645 (server, client etc.).
5647 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5649 * Added silc_server_connection_auth_request to handle the
5650 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5651 silcd/packet_receive.[ch].
5653 * Added silc_server_send_connection_auth_request into the
5654 silcd/packet_send.c to send the connection auth request packet.
5656 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5659 * Fixed the public key authentication in responder side in the
5660 server. The `auth_data' pointer includes the SilcPublicKey
5661 not the path to the public key. Affected file silcd/protocol.c.
5663 * Implemented the public key authentication in the initiator side
5664 in the server. Affected file silcd/protocol.c.
5666 * Removed the [RedirectClient] config section from the server
5667 configuration. Is not needed and I don't want to implement it.
5669 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5671 * Cleaned up the CMODE command in the server. It now works
5672 correctly and supports all the modes defined in the protocol.
5673 Affected file is silcd/command.c.
5675 * Added `hmac_name' field to the SilcChannelEntry in the server
5676 to hold the default HMAC of the channel. It can be set when
5677 creating the channel (with JOIN command). Affected files
5680 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5681 type to indicate the change of the current cipher and hmac
5682 on the channel. Client can safely ignore the <cipher> argument
5683 (if it chooses to do so) since the CHANNEL_KEY packet will
5684 force the channel key change anyway. The <hmac> argument is
5685 important since the client is responsible of setting the new
5686 HMAC and the hmac key into use.
5688 * Fixed the CMODE command in the client library as well.
5690 * Tested CMODE command in router environment successfully.
5692 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5694 * Show the version of the remote client (or server) when connecting
5695 to the server. It is logged to the log file. Affected file
5696 is silcd/protocol.c.
5698 * Fixed the KILLED notify handling in the client library. The
5699 client must be removed from all channels when receiving the
5702 Also, do not remove the client entry when giving the KILL
5703 command but when the KILLED notify is received.
5705 * Removed silc_idlist_find_client_by_nickname from the server.
5706 Not needed anymore. Affected files silcd/idlist.[ch].
5708 * Implemented the CHANNEL_CHANGE notify type handling to the
5709 server. Affected file silcd/server.c.
5713 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5715 * Added silc_server_send_notify_invite to send the INVITE
5716 notify between routers.
5718 * Implemented the INVITE command correctly to the server.
5720 * Implemented the INVITE notify type handling in the server.
5722 * Implemented the INVITE command to the client library and on the
5725 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5727 * Added function silc_server_get_client_resolve to find the
5728 client entry by ID from all ID lists and then resolve it
5729 (using WHOIS) if it cannot be found. Affected file is
5732 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5734 * Implemented the BAN command to the client library.
5736 * The JOIN command in the server now checks the invite list
5739 * Changed the silc_command_reply_payload_encode_va and the
5740 silc_command_payload_encode_va to support that if argument is
5741 NULL it ignores and checks the next argument. Affected file
5742 lib/silccore/silccommand.c.
5744 * Added silc_server_send_notify_ban to send the BAN notify
5745 type between routers.
5747 * Chaned the silc_notify_payload_encode to support that if
5748 argument is NULL it ignores and checks the next argument.
5749 Affected file lib/silccore/silcnotify.c.
5751 * Tested ban lists in router environment successfully.
5753 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5755 * Implemented BAN command to the server, in silcd/command.[ch].
5757 * Removed the BAN and INVITE_LIST modes from the CMODE command
5760 * Added function silc_string_match to regex match two strings.
5761 Affected files lib/silcutil/silcutil.[ch].
5763 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5765 * Redefined parts of the SilcChannelEntry in the server to support
5766 the new ban and invite lists.
5768 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5770 * Redefined the INVITE command. The same command can be used to
5771 invite individuals to the channel but also to manage the invite
5772 list of the channel (to add to and remove from the invite list).
5773 Updated the protocol specs.
5775 * Added new command SILC_COMMAND_BAN that can be used to manage
5776 the ban list of the channel. Updated the protocol specs.
5778 * Removed the channel modes: the SILC_CMODE_BAN and the
5779 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5780 in the CMODE command. The equivalent features are now available
5781 using INVITE and BAN commands. Updated the protocol specs.
5783 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5784 in the network about change in the current ban list. The notify
5785 type is not used by the client.
5787 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5788 support the invite lists.
5790 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5792 * Added new function silc_string_regexify that converts string
5793 including wildcard characters into regex string that can
5794 be used by the GNU regex library. Added into the file
5795 lib/silcutil/silcutil.[ch].
5797 Added silc_string_regex_combine to combine to regex strings
5798 into one so that they can be used as one regex string by
5799 the GNU regex library. Added into the file
5800 lib/silcutil/silcutil.[ch].
5802 Added silc_string_regex_match to match two strings. It returns
5803 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5805 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5807 * Imported GNU regex to the soruce tree into lib/contrib.
5808 Fixed some compiler warning from the regex.c.
5810 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5812 * Fixed MOTD command in the server to work in router environment.
5814 * Fixed the MOTD command in the client library to support
5815 the server argument in the command.
5817 * Added `nickname_len' argument to the silc_idlist_add_client
5818 in the server, as the `nickname' argument may be binary data
5821 * Added silc_idlist_get_channels to return all channels from
5824 * Implemented LIST command to the server. Affected file is
5827 * Implemented the LIST command to the client library and on the
5830 * Added [<user count>] argument to the LIST command reply.
5831 With private channels the user count is not shown.
5833 * Updated TODO and README.
5835 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5837 * The client entry's data.registered must be TRUE even with
5838 global client entry on global client list. The data.registered
5839 is used to check whether the client is anymore in the network,
5840 for example with WHOWAS command so it must be valid.
5842 * Fixed the WHOWAS command in the server. It now actually works
5843 in router environment. Added function into silcd/command_reply.c
5844 silc_server_command_reply_whowas_save.
5846 * Added silc_idlist_purge function to the silcd/idlist.c
5847 to periodically purge the ID Cache.
5849 * Fixed INFO command in the server. It works now in router
5850 environment. Added <server name> argument to the INFO command
5851 reply. Updated the protocol specs.
5853 * Fixed minor bug in silc_idcache_purge to not purge if the
5854 expire value is zero.
5856 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5857 they were buggy because of the WHOWAS information.
5859 * Fixed local command MSG to handle the async resolving of
5860 the remote client properly. It used to fail the first MSG.
5861 Affected file silc/local_command.c.
5863 * Added `data_len' field to SilcIDCache context.
5865 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5867 * Update TODO. Todo in commands in the server.
5869 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5871 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5872 used by routers as broadcast packet to inform other routers
5873 about the changed user mode.
5875 Implemented the notify handling in the server. Affected file is
5876 silcd/packet_receive.c. Added the function
5877 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5879 * Added new generic Channel Payload and deprecated the New Channel
5880 Payload. The New Channel Payload is now the generic Channel
5883 * Added new argument `mode' to the silc_server_send_new_channel
5884 as it is required in the Channel Payload now.
5886 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5887 and created a new and real SilChannelPayload to represent the
5888 new generic Channel Payload. Implemented the encode/decode
5889 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5891 * Added silc_server_get_client_channel_list to return the list
5892 of channels the client has joined for WHOIS command reply.
5893 Affected file silcd/server.[ch].
5895 * Implemented the channel list sending in the WHOIS command reply
5896 in server and in the client.
5898 Implemented the channel list displaying on the user interface
5899 as well. Affected file silc/client_ops.c.
5901 * Added silc_channel_payload_parse_list to parse list of Channel
5902 Payloads. It returns SilcDList list of SilcChannelPayloads.
5903 Client for example can use this function to parse the list of
5904 channels it receives in the WHOIS command reply. The caller
5905 must free the list by calling silc_channel_payload_list_free.
5906 Affected files lib/silccore/silcchannel.[ch].
5908 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5910 * Added one new argument <user mode> to the WHOIS command reply
5911 to return the mode of the user in SILC. Updated the protocol
5914 Implemented it to the server and client.
5916 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5918 * Fixed the mode printing on the user interface on joining.
5919 Affected file silc/client_ops.c.
5921 * Implemented the UMODE command and user modes in general to the
5922 client library and to the user interface.
5924 * Implemented the UMODE command to the server.
5926 * The server now sends UNKNOWN_COMMAND error status if client sends
5927 unknown command. Affected file silcd/command.c.
5929 * All server commands now handle the command identifier the right
5930 way when sending the command reply to the client. The client can
5931 use to identify the command replies with the identifier.
5933 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5935 * Added silc_server_get_client_route to resolve the route to
5936 the client indicated by the client ID. Affected file is
5939 * Added silc_server_relay_packet as general function to relay
5940 packet to arbitrary destination. This deprecates functions
5941 like _send_private_message_key, _relay_notify etc. Affected
5942 file is silcd/packet_send.[ch].
5944 Removed silc_server_send_key_agreement,
5945 silc_server_send_private_message_key and
5946 silc_server_packet_relay_notify functions from the file
5947 silcd/packet_send.[ch].
5951 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5952 server. Affected file silcd/packet_receive.[ch].
5954 * Implemented the KILL command to the client. Implemented the
5955 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5956 Affected files lib/silcclient/command[_reply].c and
5957 lib/silcclient/client_notify.c. Implemented the KILL notify
5958 printing in the user inteface.
5960 * Fixed a lot silc_parse_nick memory leaks from the client
5961 library in the file lib/silcclient/command.c.
5963 * Changed the silc_server_send_notify_on_channels's `sender'
5964 argument from SilcSocketConnection to SilcClientEntry to
5965 check the sender as entry and not as connection object and not
5966 to send to the client provided as argument. The affected file
5967 is silcd/packet_send.[ch].
5969 * The notify packets that are destined directly to the client used
5970 to not to be processed by the server. Now changed that and the
5971 server processes all notify packets. After relaying the packet
5972 to the client the notify packet is processed in the server.
5974 * The silc_server_free_client_data now checks whether there is
5975 pending outgoing traffic for the client and purges the data to
5976 the network before removing the client entry.
5978 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5980 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5981 an client is killed from the SILC Network. Updated the protocol
5984 Added new function silc_server_send_notify_killed to the
5985 silcd/packet_send.[ch].
5987 * Added function silc_server_packet_relay_notify to relay notify
5988 packets that are destined directly to a client. In this case
5989 the server does not process the notify packets but merely relays
5990 it to the client. Affected file silcd/packet_send.[ch].
5992 Added also silc_server_packet_process_relay_notify to check
5993 whereto relay the notify. Affected file is
5994 silcd/packet_receive.[ch].
5996 * Implemented the KILL command to the server.
6000 * Added the backup schema desgined last fall to the protocol
6001 specs for everyone to see. The specification is in the
6002 *-spec-xx.txt draft and the packet type definitions for the
6003 backup routers is in *-pp-xx.txt draft. Thusly, added also
6004 new packet type SILC_PACKET_CELL_ROUTERS.
6006 * A big security problem in the implementation discovered. The
6007 signoff of an client did not cause new channel key generation
6008 which it of course should've done. The channel keys must be
6009 always re-generated when client leaves (or signoffs) the channel.
6010 The silc_server_remove_from_channels funtion now handles
6011 the channel key re-generation.
6013 * Added `sender' argument to the silc_server_send_notify_on_channels
6014 to not to send the client provided as argument. Affected file
6015 silcd/packet_send.[ch].
6017 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6019 * Implemented OPER and SILCOPER commands into the server and
6022 * Added silc_auth_verify and silc_auth_verify_data to verify
6023 the authentication directly from the authentication payload.
6024 It supports verifying both passphrase and public key based
6025 authentication. Affected file lib/silccore/silcauth.[ch].
6027 * Added `hash' field to the SilcIDListData structure. It is the
6028 hash negotiated in the SKE protocol. Affected file is
6031 * Slight redesigning of the SilcAuthPayload handling routines.
6032 Do not send SilcPKCS but SilcPublicKey as argument.
6034 * Implemented the public key authentication support to the
6035 serverconfig. The public key is loaded from the provided path
6036 and saved as authentication data to void * pointer. Thus,
6037 changed the unsigned char *auth_data to void *auth_data;
6039 * Fixed SHUTDOWN command to send the reply before the server
6040 is shutdown. :) Affected file silcd/command.c.
6042 * Fixed fatal bug in CONNECT command. The hostname was invalid
6043 memory and server crashed. Affected file silcd/command.c.
6045 * Fixed fatal bug in CLOSE command. The server_entry became
6046 invalid but was referenced later in the command. Affected file
6049 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6051 * Fixed fatal bug in failure packet handling. Server ignored
6052 the failure and thus crashed when it came.
6056 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6058 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
6059 that the command may be executed only once in (about) 2 seconds.
6060 The old SILC_CF_LAG flag is same but allows command bursts up
6061 to five before limiting.
6063 Added the support for CF_LAG and CF_LAG_STRICT flags to the
6064 server code. Various commands now includes the CF_LAG_STRICT
6065 flag to disallow any kind of miss-use of the command.
6067 * Fixed the silc_buffer_unformat to not to allocate any data
6068 if the length of the data is zero. It used to allocate the
6069 length + 1. Affected file lib/silcutil/silcbuffmt.c.
6071 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6073 * Changed the format of AdminConnection configuration section
6074 in the server. Added username of the admin to the format.
6075 Affected files silcd/serverconfig.[ch].
6077 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
6078 to return admin configuration data by host, username and/or
6081 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6083 * Implemented WHOWAS command to the server. Added the functions:
6085 silc_server_command_whowas_parse,
6086 silc_server_command_whowas_send_reply,
6087 silc_server_command_whowas_from_client and
6088 silc_server_command_whowas_from_server
6090 * Added <Client ID> argument to the WHOWAS command reply. Updated
6091 the protocol specs accordingly.
6093 * Implemented WHOWAS command and command_reply to the client
6096 Implemented the WHOWAS printing on the user interface.
6098 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6100 * Added new argument to the WHOWAS command reply, the real name.
6101 It is an optional argument. Updated the protocol specs.
6103 * Added SilcIDCacheDestructor callback that is registered when
6104 the SilcIDCache is allocated. The callback is called when
6105 an cache entry in the ID Cache expires, or is purged from the
6106 cache. Added into lib/silccore/idcache.[ch].
6108 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
6109 to destruct the client entries when the cache entry expires.
6110 Other ID Cache's in server and in the client library ignores
6113 * If the ID Cache entry's `expire' field is zero then the entry
6114 never expires. Added boolean `expire' argument to the
6115 silc_idcache_add function in the lib/silccore/idcache.[ch].
6116 If it is TRUE the default expiry value is used.
6118 * Added silc_server_free_client_data_timeout that is registered
6119 when client disconnects. By default for 5 minutes we preserve
6120 the client entry for history - for WHOWAS command.
6122 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6124 * Added support to the server to enforce that commands are not
6125 executed more than once in 2 seconds. If server receives
6126 commands from client more frequently, timeout is registered
6127 to process the commands. Affected file silcd/command.c.
6128 Added new function silc_server_command_process_timeout.
6130 * Changed NICK_NOTIFY handling in client library to check that
6131 if the client's nickname was changed, so there is no need to
6132 resolve anything from the server.
6134 * Removed error printing from the WHOIS and IDENTIFY commands.
6135 If error occurs then it is ignored silently in the client library.
6136 The application, however, may map the received error to
6137 human readable error string. The application currently maps
6138 the NO_SUCH_NICKNAME error to string.
6140 * Made the command status message public to the application. Moved
6141 them from lib/silcclient/command_reply.c to
6142 lib/silcclient/command_reply.h. The application can map the
6143 received command status to the string with the
6144 silc_client_command_status_message function.
6146 * Added check to the server to check that client's ID is same
6147 as the Source ID in the packet the client sent. They must
6150 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6152 * Added dist-bzip hook to the Makefile.am to make bzip2
6153 compressed distributions.
6155 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6157 * Server now enforces the maximum length for the nickname and
6158 the channel as protocol specification dictates. 128 bytes for
6159 nickname and 256 bytes for channel name.
6161 * Moved the WHOIS printing to the application. The client libary
6162 does not print out the WHOIS information anymore, the application
6163 must do it. Renamed silc_client_command_reply_whois_print to
6164 the silc_client_command_reply_whois_save.
6166 The client's idle time is also sent to the application now, and
6167 the idle is shown on screen.
6169 * Added silc_client_command_reply_identify_save to save the
6170 received IDENTIFY entries.
6172 * Do not check for channel private keys in message sending and
6173 reception if the channel does not have the PRIVKEY mode set.
6174 Affected file lib/silclient/client_channel.c.
6176 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6178 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
6179 just surfaced after chaning the JOIN procedure.
6181 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6183 * Added silc_client_get_clients_by_list to get client entries
6184 from Client ID list, that is returned for example by JOIN
6185 and USERS command replies. The application should use this
6186 function for example when JOIN command reply is received to
6187 resolve the clients already on the channel (library does not
6188 do that anymore as USERS command reply is not used in the JOIN
6189 procedure anymore). Affected files lib/silcclient/silcapi.h and
6190 lib/silcclient/idlist.c.
6192 * JOIN command reply and USERS command reply returns now SilcBuffer
6193 pointers instead of unsigned char pointers when returning
6194 the client list and mode list.
6196 * Added <Client ID> argument to the JOIN command reply, mainly
6197 for the server to identify for which client the command was
6198 originally sent. Updated protocol specs accordingly.
6200 * Added SilcDlist private_key pointer to the SilcChannelEntry
6201 in the client to support the channel private keys. Affected
6202 file is lib/silcclient/idlist.h.
6204 * Added SilcChannelPrivateKey argument to the function
6205 silc_client_send_channel_message so that application can choose
6206 to use specific private ke if it wants to. If it is not provided,
6207 the normal channel key is used, unless private keys are set.
6208 In this case the first (key that was added first) is used
6209 as the encryption key.
6211 * Implemented the support for channel private key handling.
6212 Implemented the following functions:
6214 silc_client_add_channel_private_key,
6215 silc_client_del_channel_private_keys,
6216 silc_client_del_channel_private_key,
6217 silc_client_list_channel_private_keys and
6218 silc_client_free_channel_private_keys
6220 Affected file lib/silcclient/client_channel.c.
6222 * Added the support for the private keys in the channel message
6223 sending and encryption and in the message reception and
6224 decryption. Affected funtions are
6225 silc_client_send_channel_message and silc_client_channel_message.
6227 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6229 * Added SKE's key verify callback to the client library's
6230 KE protocol context. Affected files lib/silcclient/protocol.[ch].
6232 * Removed the statement that server (or router) must send USERS
6233 command reply when joining to the channel so that the client
6234 knows who are on the channel. Instead, the client list and
6235 client's mode list is now sent in the JOIN command reply to the
6236 client who joined channel. This is better solution.
6238 * Added function silc_server_get_users_on_channel and function
6239 silc_server_save_users_on_channel to the silcd/server.[ch].
6241 * Removed function silc_server_command_send_users from the
6244 * Do not show topic on the client library anymore. The topic is
6245 sent in the command reply notify to the application and the
6246 application must show the topic now.
6248 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6250 * Added client searching by nickname hash into the IDENTIFY and
6251 WHOIS commands in the server as they were clearly missing from
6252 them. Affected file is silcd/command.c.
6254 * Fixed a bug in private message receiving in the client library.
6255 The remote ID was freed and it wasn't supposed, now it is
6258 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6260 * Minor fix to the channel payload; allocate the data area, as it
6261 needs to be of specific length.
6263 * If the key agreement port is zero then the operating
6264 system will define the bound port. Affected files are
6265 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
6267 * Added new function silc_channel_payload_decrypt into the file
6268 lib/silccore/silcchannel.[ch].
6270 * Moved the channel message etc, check from silc_packet_decrypt
6271 to applications. The library calls now a generic
6272 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
6273 when the packet is either normal or special. This was done to
6274 allow more wide range of checking that was not allowed when
6275 the code was in library. Now applications can do virtually any
6276 checks to the packet and return to the library the decision how
6277 the packet should be processed. Affected files are
6278 lib/silccore/silcpacket.[ch].
6280 Added silc_server_packet_decrypt_check to the server and
6281 silc_client_packet_decrypt_check to the client library.
6283 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
6284 to send with specified source and destination information.
6286 * Channel message delivery between routers was broken after the
6287 channel key distribution was fixed earlier. The channel key
6288 was used be to distributed to other routers as well which is not
6289 allowed by the protocol. Now this is fixed and channel keys
6290 really are cell specific and the channel message delivery between
6291 routers comply with the protocol specification.
6293 * Fixed various commands in server to check also the global list
6294 for the channel entry and not just the local list. The affected
6295 file silcd/command.c.
6297 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6299 * Added assert()s to buffer formatting and unformatting routines
6300 to assert (if --enable-debug) when error occurs. Affected
6301 file: lib/silcutil/silcbuffmt.c.
6303 * Changed to auto-reconnect to check whether the remote host is
6304 router and register the re-connect timeout if it is. It used
6305 to check that whether we are normal server, but router must do
6306 auto-reconnect with another router as well. Affected file
6309 * Removed the [<key len>] option from CMODE command as the cipher
6310 name decides the key length, nowadays. See the defined ciphers
6311 from the protocol specification.
6313 * Added [<hmac>] option to the CMODE command to define the HMAC
6314 for the channel. Added SILC_CMODE_HMAC channel mode.
6316 * Added [<hmac>] option for the JOIN command so that user can
6317 select which HMAC is used to compute the MACs of the channel
6320 * Added Hmac field to the Channel Message Payload. The integrity
6321 of plaintext channel messages are now protected by computing
6322 MAC of the message and attaching the MAC to the payload. The
6323 MAC is encrypted. Now, it is clear that this causes some
6324 overhead to the size of the packet but rationale for this is that
6325 now the receiver can verify whether the channel message decrypted
6326 correctly and also when private keys are set for the channel the
6327 receiver can decrypt the packet with several keys and check from
6328 the MAC which key decrypted the message correctly.
6330 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
6331 lib/silccrypt/silccipher.[ch].
6333 * Added silc_hash_len to return the digest length into the
6334 lib/silcrypt/silchash.[ch].
6336 * Rewrote parts of Silc Channel Payload interface in the
6337 lib/silccore/silcchannel.[ch]. The encode function now also
6338 encrypts the packet and parse function decrypts it.
6340 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6342 * Fixed a minor formatting bug in the SKE's key material processing.
6343 It actually might have processed the keys wrong way resulting
6346 * Redefined the mandatory HMAC algorithms and added new algorithms.
6347 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
6348 and hmac-md5 truncated to 96 bits. The mandatory is now
6349 hmac-sha1-96. Rest are optional (including the one that used
6350 to be mandatory). Rationale for this is that the truncated HMAC
6351 length is sufficient from security point of view and can actually
6352 make the attack against the HMAC harder. Also, the truncated
6353 HMAC causes less overhead to the packets. See the RFC2104 for
6356 * Added new [hmac] configuration section. The SKE used to use
6357 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
6358 is of course wrong. The official names that must be proposed in
6359 the SKE are the ones defined in the protocol specification
6360 (hmac-sha1-96 for example). The user can configure any hmac
6361 using any hash function configured in the [hash] section. At
6362 least, the mandatory must be configured.
6364 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
6366 * Added HMAC list to the SKE proposal list. It has now both
6367 hash algorithm list and HMAC list. This makes the protocol
6368 incompatible with previous versions. The SKE now seems to work
6369 the way it is supposed to work, for the first time actually.
6371 * Defined plain Hash algorithms to the protocol specification.
6374 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6376 * Implemented support for key agreement packets into the server.
6377 Added functions silc_server_key_agreement and
6378 silc_server_send_key_agreement. Other than these functions,
6379 server has nothing to do with this packet.
6381 * Added support for private message key packets into the server.
6382 Added functions silc_server_private_message_key and
6383 silc_server_send_private_message_key.
6387 * Changed the silc_[client|server]_protocol_ke_set_keys to be
6388 called in the protocol's final callback instead in the END
6389 protocol state. This makes a little more sense and in the same
6390 time in client we can use the same protocol routines for normal
6391 key exchange and to key agreement packet handling as well.
6393 * Added to both client's and server's KE protocol context the
6394 SilcSKEKeyMaterial pointer to save the key material. We will
6395 bring the key material to the protocol's final callback by doing
6396 this. The final callback must free the key material.
6398 * Added SKE's packet_send callback into client's KE protocol
6399 context so that the caller can choose what packet sending function
6400 is used. This way we can use different packet sending when
6401 doing normal SKE when doing key agreement packet handling (in
6402 the key agreement packet handling we do not want to encrypt
6405 * Implemented the responder side of the key agreement routines
6406 in the client. The client can now bind to specified port and
6407 accept incoming key negotiation. The key material is passed
6408 to the application after the protocol is over.
6410 * Implemented the processing of incoming Key Agreement packet
6411 in the client. Added function silc_client_key_agreement to
6414 * Implemented the intiator side of the key agreement routines
6415 in the client. The client can now initiate key agreement with
6416 another remote client. The key material is passed to the
6417 application after the protocol is over.
6419 * Created client_keyagr.c to include all the key agreement
6422 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
6423 SILC_TASK_CALLBACK except that it is not static.
6425 * Created client_notify.c and moved the Notify packet handling
6426 from the client.[ch] into that file.
6428 * Created client_prvmsg.c and moved all private message and
6429 private message key routines from the client.[ch] into that file.
6431 * Create client_channel.c and moved all channel message and
6432 channel private key routines from the client.[ch] into that file.
6434 * Changed silc_client_get_client_by_id_resolve to resolve with
6435 WHOIS command instead of IDENTIFY command, in the file
6436 lib/silclient/idlist.c.
6438 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6440 * Implemented the SKE's responder side to the Client library.
6442 * When FAILURE is received to the protocol do not trust it
6443 blindly. Register a timeout to wait whether the remote closes
6444 the connection as it should do it, only after that process the
6445 actual failure. This was changed to both client and server.
6447 * Added client_internal.h to include some of the structures
6448 there instead of client.h in lib/silcclient/.
6450 * Added function silc_task_unregister_by_callback to unregister
6451 timeouts by the callback function.
6453 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6455 * Some "Incomplete WHOIS info" errors has been appearing on the
6456 log files. Took away the entry->userinfo check from WHOIS
6457 reply sending. The entry->userinfo is now " " if client did not
6458 provide one. I thought this was fixed earlier but something
6459 is wrong still. Let's see if the error still appears.
6461 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6463 * Fixed a minor bug in the login when the channel key is
6464 re-generated in the server. It used to generate the key in
6465 wrong order and thus caused problems in the channel traffic.
6467 * Fixed a minor bug in channel key distsribution after
6468 KICK command. The key was not sent to the router even though
6471 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6473 * Added silc_ske_process_key_material_data as generic routine
6474 to process any key material as the SILC protocol dictates. The
6475 function is used by the actual SKE library but can be used by
6476 applications as well. This relates to the private message keys
6477 and the channel private keys since they must be processed the
6478 same way the normal SILC session keys. The protocol dictates
6479 this. Affected files: lib/silcske/silcske.[ch].
6481 Added also silc_ske_free_key_material to free the
6482 SilcSKEKeyMaterial structure.
6484 * Defined silc_cipher_set_key function to set the key for
6485 cipher without using the object's method function. The affected
6486 files: lib/silccrypt/silccipher.[ch].
6488 * Implemented silc silc_client_add_private_message_key,
6489 silc_client_add_private_message_key_ske,
6490 silc_client_del_private_message_key,
6491 silc_client_list_private_message_keys and
6492 silc_client_free_private_message_keys functions in the
6495 Added functions silc_client_send_private_message_key to send
6496 the Private Message Key payload and silc_client_private_message_key
6497 to handle incoming Private Message Key payload.
6499 * Added Cipher field to the Private Message Key payload to set
6500 the cipher to be used. If ignored, the default cipher defined
6501 in the SILC protocol (aes-256-cbc) is used.
6503 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6505 * Removed lib/silcclient/ops.h file.
6507 Redefined parts of the SILC Client Library API. Created new
6508 file silcapi.h that deprecates the ops.h file and defines the
6509 published Client Library API. Defined also private message key
6510 API and channel private key API into the file.
6512 This is the file that the application must include from the
6513 SILC Client Library. Other files need not be included by
6514 the application anymore.
6516 * Added new key_agreement client operation callback and also
6517 defined the Key Agreement library API for the application.
6519 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6521 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
6522 is used by clients to request key negotiation between another
6523 client in the SILC network. If the negotiation is started it
6524 is performed using the SKE protocol. The result of the
6525 negotiation, the secret key material, can be used for example
6526 as private message key.
6528 Implemented the Key Agreement payload into the files
6529 lib/silccore/silauth.[ch].
6531 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6533 * Redefined ciphers for the SILC protocol. Added some new ciphers
6534 and defined the key lengths for the algorithms. Changed the
6535 code accordingly. The default key length is now 256 bits.
6537 * Fixed SKE key distribution function silc_ske_process_key_material
6538 when the key length is more than 128 bits. The default key
6539 length in SILC is now 256 bits.
6541 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
6542 to indicate unsupported algorithm.
6544 * Renamed rijndael.c to aes.c and all functions as well.
6546 * Fixed a long standing channel key setting bug in client library.
6547 Weird that it has never surfaced before.
6549 * Fixed bug in channel deletion. If the entire channel is removed
6550 then it must also delete the references of the channel entry
6551 from the client's channel list as the client's channel entry and
6552 the channel's client entry share same memory.
6554 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6556 * Implemented CONNECT and SHUTDOWN commands in the client.
6558 * Implemented CLOSE command to the client.
6560 * Added the function silc_idlist_find_server_by_name into the
6561 files silcd/idlist.[ch].
6563 Added the function silc_idlist_find_server_by_conn into the
6564 files silcd/idlist.[ch].
6566 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6568 * DIE command was renamed to SHUTDOWN. Updated the both code
6571 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
6572 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
6574 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
6577 * Added function silc_server_create_connection function to create
6578 connection to remote router. My server implementation actually
6579 does not allow router to connect to normal server (it expects
6580 that normal server always initiates the connection to the router)
6581 so the CONNECT command is only good for connecting to another
6584 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6586 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
6587 or some other client was kicked from the channel.
6589 Implemented the handling of the notify type to both client
6592 Implemented silc_server_send_notify_kicked to send the KICKED
6593 notify. It is used to send it to the server's primary router.
6595 * Implemented the KICK command into server and client.
6597 * Added `query' argument to the silc_idlist_get_client function
6598 to indicate whether to query the client from server or not if
6601 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
6602 to indicate that the client is not channel founder.
6606 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6608 * Removed the rng context from SilcPacketContext structure and
6609 changed that the packet routine uses the Global RNG API.
6611 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6613 * Added support for quit message that client can "leave" on the
6614 channel when it quits the SILC. It is ditributed inside the
6615 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6617 Added silc_server_free_client_data that will take the
6618 signoff message as argument.
6620 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6622 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6624 * Updated parts of the protocol specification to keep it up
6627 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6629 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6630 payloads in one packet.
6632 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6633 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6634 use now the new List flag.
6636 * Also deprecated the following packet types: REPLACE_ID,
6637 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6639 * Added list support for Notify packet in server.
6641 * Added silc_server_send_notify_channel_change to send the
6642 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6643 the silc_server_send_replace_id.
6645 * Added silc_server_send_notify_nick_change to send the
6646 NICK_CHANGE notify type. Deprecates the function
6647 silc_server_send_replace_id.
6649 * Added silc_server_send_notify_join to send the JOIN notify type.
6650 Deprecates the function silc_server_send_new_channel_user.
6652 * Added silc_server_send_notify_leave to send LEAVE notify type.
6653 Deprecates the function silc_server_send_remove_channel_user.
6655 * Added silc_server_send_notify_cmode and
6656 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6657 types. Deprecates the silc_server_send_set_mode function.
6659 * Added SERVER_SIGNOFF notify type to indicate that server has
6660 quit. This means that all clients on the channel from that
6661 server will drop. This can be also used when netsplit happens.
6663 Deprecated REMOVE_ID packet type since it is not needed anymore
6666 Added silc_server_send_notify_server_signoff to send the
6667 SERVER_SIGNOFF notify type. Deprecates the function
6668 silc_server_send_remove_id.
6670 Added also silc_server_send_notify_signoff to send the
6671 SIGNOFF notify type.
6673 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6674 SILC protocol from this day on. Changed the protocol
6675 specification as well.
6677 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6678 notify type. It is used between routers to notify about
6679 topic changes on a channel.
6681 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6684 * Partly updated the protocol specification to comply with the
6685 changes now made. It is still though a bit outdated.
6687 * The JOIN notify type now takes one extra argument <Channel ID>.
6688 The packet used to be destined to the channel but now the
6689 JOIN type may be sent as list thus it is impossible to
6690 destine it to any specific channel. By adding this argument
6691 it is again possible.
6693 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6695 * Added CREDITS file. The CHANGES and CREDITS file will appear
6696 in the distribution as well.
6698 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6700 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6701 types in the server's silcd/packet_receive.c.
6703 * Implemented CMODE and CUMODE to work in router environment.
6705 * Fixed minor encoding and decoding buglet from the
6706 lib/silccore/silcmode.c.
6708 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6711 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6713 * Changed all SilcConfigServer* and silc_config_server* to
6714 SilcServerConfig* and silc_server_config*, respectively.
6717 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6719 * Associated the ID (client or server ID) to the Authentication
6720 Payload to avoid any possibility of forging. Updated the
6721 protocol specification and the code accordingly.
6723 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6725 * The RSA key length is now save to the RsaKey context in the
6726 key generation process in lib/silccrypt/rsa.c. The key length
6727 is now used to figure out the maximum size of the block allowed
6728 to be encrypted/signed.
6730 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6731 is equivalent to the silc_mp_mp2bin but does not allocate any
6734 * Changed silc_mp_mp2bin API to take length argument. If it is
6735 non-zero then the buffer is allocated that large. If zero, then
6736 the size is approximated using silc_mp_sizeinbase, which however
6739 * Created Global RNG API which is global RNG that application can
6740 initialize. After initializing, any routine anywhere in the
6741 code (including library) can use RNG without allocating a new
6742 RNG object. This was done to allow this sort of use of the
6743 RNG in code that has no chance to allocate RNG object. All
6744 applications currently allocate this and many routines in the
6745 library use this. Affected file lib/silccrypt/silcrng.[ch].
6747 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6748 it to use the Global RNG API.
6750 * Defined Authentication Payload into protocol specification that
6751 is used during SILC session to authenticate entities. It is
6752 used for example by client to authenticate itself to the server
6753 to obtain server operator privileges.
6755 Implemented this payload into the lib/silccore/silcauth.[ch].
6756 Implemented also routines for public key based authentication
6757 as the new protocol specification dictates.
6759 Moved definitions of different authentication methods from
6760 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6762 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6763 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6764 silc_pkcs_verify_with_hash functions into the file
6765 lib/silccrypt/silcpkcs.[ch].
6767 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6769 * The client entry's userinfo pointer must be always valid.
6770 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6771 will fail since it requires the userinfo. Now, the userinfo
6772 is allocated as "" if actual userinfo does not exist. Actually,
6773 it must exist and it is totally Ok to drop client connections
6774 that does not announce the userinfo. However, we will make
6775 this workaround for now.
6777 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6778 to return the remote port by socket.
6780 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6782 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6783 SILC_SERVER_PENDING_EXEC and added an new macro
6784 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6785 data or when error occurs while processing the pending command.
6787 Added new argument `destructor' into silc_server_command_pending
6788 and to the SilcServerCommandPending object. This destructor is
6789 now called after calling the pending callback or if error occurs
6790 immediately. If error occurs the actual pending callback won't
6791 be called at all - only the destructor. The destructor may be
6792 NULL if destructor is not needed.
6794 All this applies for client library code as well. Similar
6795 changes were made there as well for the pending commands.
6797 In the client, the application must now allocate the
6798 SilcClientCommandContext with the silc_client_command_alloc
6801 * Added reference counter to the SilcServerCommandContext. Added
6802 function silc_server_command_alloc and silc_server_command_dup
6805 Same type of functions added to the client library for the same
6808 * Removed the cmd_ident from IDListData away since it is now
6809 global for all connections. It is the command identifier used
6810 in command sending and with pending commands. The affected file
6813 * Added reference counter to the SilcSocketConnection objecet to
6814 indicate the usage count of the object. The object won't be
6815 freed untill the reference counter hits zero. Currently only
6816 server uses this, and client ignores it. The client must be
6817 set to use this too later. The affected files are
6818 lib/silccore/silcsockconn.[ch]. Added also the function
6819 silc_socket_dup to increase the reference counter.
6821 This was mainly added because it is possible that the socket
6822 is removed underneath of pending command or other async
6823 operation. Now it won't be free'd and proper DISCONNECTING
6824 flags, etc. can be set to avoid sending data to connection that
6825 is not valid anymore.
6827 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6828 the connection. After that it sets SILC_SET_DISCONNECTED.
6829 It is, however, possible that the socket data is not still freed.
6830 The silc_server_packet_process now checks that data is not
6831 read or written to connection that is DISCONNECTED. The socket
6832 get's freed when the reference counter hits zero.
6834 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6836 * Changed the client operation API: channel_message operation's
6837 `sender' is now the client entry of the sender, not the nickname
6838 and the `channel' is the channel entry, not the channel name.
6840 In the private_message operation the `sender' is now also the
6841 client entry of the sender not the nickname.
6843 Affected file is lib/silcclient/ops.h and all applications
6844 using the client operations.
6846 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6848 * Moved the calling of ops->connect() from connect_to_server_final
6849 into receive_new_id functin since that is the point when the
6850 client is actually allowed to send traffic to network. The
6851 affected file is lib/silcclient/client.c.
6853 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6855 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6856 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6857 (if needs broadcasting) instead of broadcasting the packets one
6858 by one which would make a burst in the network traffic.
6860 * Added `broadcast' argument to the functions in silcd/server.[ch]
6861 silc_server_create_new_channel[_with_id] to indicate whether
6862 to send New Channel packet to primary router.
6864 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6866 * Added new function into the silcd/server.[ch] files:
6867 silc_server_create_new_channel_with_id to create new channel with
6868 already existing Channel ID.
6870 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6871 lib/silccore/silcpacket.h. This packet is used t send list of
6872 Set Mode payloads inside one packet. Server uses this to set
6873 the modes for the channels and clients on those channels, that it
6874 announced to the router when it connected to it. The protocol
6875 specification has been updated accordingly.
6877 * The silc_server_new_channel did not handle the packet coming
6878 from normal server as it normally does not send that. However,
6879 when it announces its channels it does send it. Implemented
6880 the support for that.
6882 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6883 into the file lib/silccore/id.h.
6885 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6887 * Fixed memory leaks in the functions silc_idlist_del_client,
6888 silc_idlist_del_channel and silc_idlist_del_server in the file
6889 silcd/idlist.c. All of those leaked like a sieve.
6891 * Fixed some small memory leaks in the client's function
6892 silc_client_notify_by_server.
6894 * Added functions into silcd/server.c: silc_server_announce_clients,
6895 silc_server_announce_channels and silc_server_announce_server.
6896 These functions are used by normal and router server to announce
6897 to its primary router about clients, channels and servers (when
6898 router) that we own. This is done after we've connected to the
6901 These functions effectively implements the following packet types:
6902 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6903 and SILC_PACKET_NEW_ID_LIST.
6905 * Added new functions into the silcd/packet_receive.[ch]:
6906 silc_server_new_id_list, silc_server_new_channel_list and
6907 silc_server_new_channel_user_list to handle the incoming
6908 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6910 * Added support of changing Channel ID in the function
6911 silc_server_replace_id. If the server that announces a channel
6912 to the router already exists in the router (with same name but
6913 with different Channel ID), router is responsible to send
6914 Replace ID packet to the server and force the server to change
6915 the Channel ID to the one router has.
6917 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6918 client that the Channel ID has been changed by the router. The
6919 normal server sends this to the client. Client must start using
6920 the new Channel ID as the channel's ID.
6922 Implemented handling of this new type into lib/silcclient/client.c
6923 into the function silc_client_notify_by_server.
6925 * Added new function silc_idlist_replace_channel_id into the files
6926 silcd/idlist.[ch] to replace the Channel ID.
6928 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6930 * Call silc_server_command_identify_check always when processing
6931 the IDENTIFY command in silcd/command.c
6933 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6935 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6936 send keepalive packets. The packet can be sent by clients,
6937 servers and routers.
6939 Added function silc_socket_set_heartbeat into the file
6940 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6941 If not set, the heartbeat is not performed. The actual
6942 heartbeat is implemented in the low level socket connection
6943 library. However, application is responsible of actually
6946 Added silc_server_send_heartbeat to send the actual heartbeat
6947 packet into silcd/packet_send.[ch]. Server now performs
6948 keepalive with all connections.
6950 * Added silc_task_get_first function into lib/silcutil/silctask.c
6951 to return the timeout task with shortest timeout. There was a bug
6952 in task unregistration that caused problems. TODO has been
6953 updated to include that task system must be rewritten.
6955 * The client library will now resolve the client information when
6956 receiving JOIN notify from server for client that we know but
6957 have incomplete information.
6959 * Rewrote parts of silc_server_remove_from_channels and
6960 silc_server_remove_from_one_channel as they did not remove the
6961 channel in some circumstances even though they should've.
6963 * Encryption problem encountered in server:
6965 The LEAVE command used to send the Channel Key packet to the
6966 router immediately after generating it. However, the code
6967 had earlier sent Remove Channel user packet but not immediately,
6968 ie. it was put to queue. The order of packets in the router
6969 was that Channel Key packet was first and Remove Channel User
6970 packet was second, even though they were encrypted in the
6971 reverse order. For this reason, MAC check failed. Now, this
6972 is fixed by not sending the Channel Key packet immediately but
6973 putting it to queue. However, this is more fundamental problem:
6974 packets that are in queue should actually not be encrypted
6975 because packets that are sent immediately gets encrypted
6976 actually with wrong IV (and thus MAC check fails). So, packets
6977 that are in queue should be encrypted when they are sent to
6978 the wire and not when they put to the queue.
6980 However, the problem is that the current system has not been
6981 designed to work that way. Instead, the packet is encrypted
6982 as soon as possible and left to the queue. The queue is then
6983 just purged into wire. There won't be any fixes for this
6984 any time soon. So, the current semantic for packet sending
6987 o If you send packet to remote host and do not force the send
6988 (the packet will be in queue) then all subsequent packets to the
6989 same remote host must also be put to the queue. Only after the
6990 queue has been purged is it safe again to force the packet
6993 o If you send all packets immediately then it safe to send
6994 any of subsequent packets through the queue, however, after
6995 the first packet is put to queue then any subsequent packets
6996 must also be put to the queue.
6998 Follow these rules and everything works fine.
7000 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7002 * Added new function silc_server_remove_clients_by_server to
7003 remove all client entries from ID list when the server connection
7004 is lost. In this case it is also important to invalidate all
7005 client entires as they hold the invalid server entry. This
7006 fixes fatal bug when server has lost connection and will reconnect
7009 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7011 * Made some sanity checks to silc_server_daemonise like to check
7012 whether the requested user and group actually exists.
7014 * Added sanity check to SKE's silc_ske_responder_finish to check
7015 that the public and private key actually is valid.
7017 * Invalidate the client's nickname when receiving Replace ID
7018 packet and the Client ID is being replaced. This means that the
7019 server will query the nickname if someone needs it (client)
7022 * Sort the ID Cache in client library when the ID Cache data
7023 has changed (needs sorting).
7025 * Do not allow for SILC client to create several connections to
7026 several servers. The client does not support windows right now
7027 and generating multiple connections causes weird behaviour.
7029 Irssi-silc client does support windows and can handle several
7030 connections without problems, see: www.irssi.org and SILC plugin.
7032 * Fixed some places where client was added to the IDList. The
7033 rule of thumb is following (in order to get everything right):
7034 If the client is directly connected local client then the
7035 `connection' argument must be set and `router' argument must be
7036 NULL to silc_idlist_add_client function. If the client is not
7037 directly connected client then the `router' argument must
7038 bet set and the `connection' argument must be NULL to the
7039 silc_idlist_add_client function.
7041 * The funtion silc_server_packet_send_local_channel actually did
7042 not check whether the client was locally connected or not. It
7043 does that now. Fixed a bug related to LEAVE command.
7045 * Fixed Remove Channel User payload parsing bug in server's
7046 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
7048 * The server's silc_server_save_channel_key now checks also the
7049 global ID list for the channel as it might not be in the local
7050 list. Fixed a bug related to LEAVE command.
7052 * Is this the end of the [<unknown>] buglet that has been lurking
7053 around for a long time? A little for loop fix in server's
7054 silc_server_command_whois_parse that is used by both IDENTIFY
7055 and WHOIS command. At least, this was a clear bug and a cause
7056 of one type of [<unknown>] buglet.
7058 * WHOIS and IDENTIFY commands call the function
7059 silc_server_command_[whois/identify]_check function even if
7060 we are not router server.
7062 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7064 * Added --with-gmp configuration option. If set the GMP
7065 is always compiled in the SILC source tree. If not set then
7066 it is checked whether the system has the GMP3 installed. If
7067 it has then the GMP won't be compiled (the system's headers
7068 and library is used), if it doesn't have it then the GMP is
7069 compiled in the SILC source tree.
7071 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7073 * Changed RSA private exponent generation to what PKCS #1
7074 suggests. We try to find the smallest possible d by doing
7075 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
7076 not security fix but optimization.
7078 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7080 * Added new config entry [Identity] to fork the server and run
7081 it as specific user and group. A patch from Bostik.
7083 * Imported Dotconf configuration library into lib/dotconf.
7084 This will be used to create the SILC configuration files later.
7085 It will appear in the distsribution after this commit.
7087 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7089 * A big code auditing weekend happening. Auditing code for
7090 obvious mistakes, bugs and errors. Also, removing any code
7093 Removed files for being obsolete:
7095 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
7096 inline in the file lib/silcutil/silcbuffer.h)
7098 o lib/silcutil/silcbufutil.c (the header has inline versions)
7100 Changed code to fix possible error conditions:
7102 o The buffer formatting routines now check that the destination
7103 buffer really has enough space to add the data. This applies for
7104 both buffer formatting and unformatting
7105 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
7106 unformatting was changed to accomodate following rules:
7107 XXX_*STRING_ALLOC will allocate space for the data into the pointer
7108 sent to the function while XXX_*STRING will not allocate or copy
7109 the data into the buffer. Instead it sets the pointer from the
7110 buffer into the pointer sent as argument (XXX_*STRING used to
7111 require that the pointer must be allocated already). This change
7112 makes this whole thing a bit more consistent and more optimized
7113 (note that the data returned in the unformatting with XXX_*STRING
7114 must not be freed now). The routines return now -1 on error.
7116 o Tried to find all code that use buffer_format and buffer_unformat
7117 and added return value checking to prevent formatting and
7118 especially unformatting errors and possible subsequent fatal
7121 o Changed ske->x and ske->KEY to mallocated pointers in
7122 lib/silcske/silcske.h. Fixed possible data and memory leak.
7124 o Added return value checking to all *_parse* functions. Fixed
7125 many memory leaks as well.
7127 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
7128 so that buffer overflows would not happen. All code now also
7129 checks the return value as it can fail.
7131 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7133 * Added reconnection support to server if the normal server looses
7134 its connection to the router (for example if router is rebooted).
7135 The server performs normal reconnection strategy implemented
7136 to the server. Affected file silcd/server.c.
7138 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7140 * Added new packet type SILC_PACKET_SET_MODE that is used to
7141 distribute the information about changed modes (for clients,
7142 channels and clients channel modes) to all routers in the
7143 network. Updated the protocol specification accordingly.
7145 Added functions into silcd/packet_send.c and
7146 silcd/packet_receive.c: silc_server_send_set_mode,
7147 silc_server_set_mode.
7149 Added new files silcmode.[ch] into lib/silccore that implements
7150 the encoding and decoding of Set Mode Payload. Added new type
7151 SilcSetModePayload. Moved the definitions of different modes
7152 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
7154 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7156 * Oops, a little mistake in server's connection authentication
7157 protocol. The protocol is not ended with FAILURE but with
7158 SUCCESS if the authentication is Ok. :) Affected file is
7161 * Implemented NICK_CHANGE notify handling in server in the file
7162 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
7163 the local clients on the channel. After the changing nickname
7164 in router environment snhould work and the [<unknown>] nickname
7165 should appear no more.
7167 The silc_server_replace_id function that receives the Replace ID
7168 payload now sends the NICK_CHANGE notify type also in the file
7169 silcd/packet_receive.c
7171 * Changed WHOIS and IDENTIFY command to support the maximum amount
7172 of arguments defined in protocol specs (3328 arguments). This
7173 fixed a bug that caused problems when there were more than three
7176 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7178 * Added extra parameter, command identifier, to the
7179 silc_client_send_command so that explicit command identifier
7182 Changed that ID list routines uses specific command identifier
7183 when sending WHOIS/IDENTIFY requests to the server so that they
7184 can be identified when the reply comes back.
7186 Affected files lib/silcclient/command.[ch],
7187 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
7189 * Added `sender' argument to silc_server_packet_send_to_channel
7190 to indicaet the sender who originally sent the packet to us
7191 that we are now re-sending. Ignored if NULL. Affected file
7192 silcd/packet_send.[ch].
7194 * Added some server statistics support in silcd/server_internal.h
7195 SilcServerStatistics structure and around the server code. Also
7196 send some nice statistics information when client is connecting
7199 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7201 * Fixed channel ID decoding in server's JOIN command reply in
7202 silcd/command_reply.c
7204 * Fixed braodcasting of replace ID payload to not to send it if
7205 we are standalone server in silcd/packet_receive.c.
7207 * Fixed all channel message sending routines to not to send
7208 packets to clients that has router set, since they are routed
7209 separately in the same function earlier. Affects file
7210 silcd/packet_send.c and all channel packet sending functions.
7212 * In USERS reply, res_argv[i] are not allocated, the table
7213 is allocated. Thus changed that free the table, not its
7216 * In server's whois_check and identify_check if the client is
7217 locally connected do not send any WHOIS commands - they are not
7220 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7222 * Fixed some minor bugs in client when sending WHOIS command. The
7223 arguments was in wrong order.
7225 * Removed statis function add_to_channel from server in
7226 silcd/command.c that was previously used with the joining but
7229 * Tested USERS command in router environment successfully with two
7230 routers, two servers and two clients.
7232 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7234 * Reorganized the USERS command and command reply in client library
7235 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
7236 When the command is given by user we register a pending command
7237 callback that will reprocess the command after the reply has been
7238 received from the server. When reprocessing the packet we then
7239 display the information. Thus, the USERS information is displayed
7240 now in the command callback instead of in the command reply
7241 callback. The processing of the command is same as previously
7242 when server has sent the command reply in the JOINing process.
7244 * Added to USERS command in silcd/command_reply.c to join the client,
7245 we didn't use to know about, to the channel after we've created
7246 a client entry for it. Also, for clienet we did know already still
7247 check whether it is on the channel or not and add it if not.
7249 * Removed silc_server_command_join_notify as the function and its
7252 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7254 * Changed the client's pending command handling to the same as the
7255 server's pending command handling. It is also now possible to
7256 execute command reply functions from other command reply
7257 function as the function callbacks for commands and command
7258 replies are one and same. The pending commands are not static
7259 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
7260 in client connection context. Thus, pending commands are server
7261 connection specific as it is convenient.
7263 Changed the function silc_client_command_pending and
7264 silc_client_command_pending_del and added new function
7265 silc_client_command_pending_check. Removed the
7266 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
7269 * Added cmd_ident, current command identifier, to the client
7270 connection context in lib/silcclient/client.h to keep track on
7271 command identifiers used in command sending. Client's command reply
7272 function handling now supports the mandatory command identifiers.
7274 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
7275 funtions in client to fully support pending command callbacks.
7277 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
7278 as one of the arguments to the application in the command reply
7281 * NOTE: The FORWARDED flag is depracated. It used to be depracated
7282 before first releasing SILC but came back. Now it is removed again
7283 and should come back nomore. The FORWARDED flag was used only
7284 by the JOINing procedure by forwarding the command packet to router.
7285 Now, the JOINing procedure has been changed to more generic (due
7286 to various router environment issues) and FORWARDED is not needed
7287 anymore for anything. The protocol specification is yet to be
7290 Now, removed silc_server_packet_forward from server and the flag
7291 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
7293 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7295 * Renamed NAMES command to USERS command. The NAMES was named that
7296 due to historical reasons. Now it is renamed. Also, rewrote
7297 parts of the USERS command. The nickname list is not sent anymore
7298 by the server. Only Client ID and mode lists are sent in the USERS
7299 command. Changed this also to the protocol specification.
7301 The client now resolves the names and stuff after it receives
7302 the USERS list from the server when joining to the channel.
7304 * WHOIS and IDENTIFY commands has been changed to support multiple
7305 Client ID's per command. One can now search for multiple users
7306 in the network by sending only one WHOIS or IDENTIFY command.
7307 Changed the code and the protocol specifications.
7309 * Removed silc_server_command_identify_parse and changed that IDENTIFY
7310 uses silc_server_command_whois_parse to parse the request. */
7312 * If normal server, do not parse the WHOIS and IDENTIFY requests
7313 before sending it to the router. Saves some time.
7315 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7317 * Fixed JOIN command on client library. Wrong number of arguments
7318 used to crash the client.
7320 * Added silc_server_channel_has_global function to check whether
7321 channel has global users or not.
7323 * Added silc_server_channel_has_local function to check whether channel
7324 has locally connected clients on the channel.
7326 * The silc_server_remove_from_one_channel now checks whether the
7327 channel has global users or not after given client was removed from
7328 the channel. It also checks whether the channel has local clients
7329 on the channel anymore. If it does not have then the channel entry
7330 is removed as it is not needed anymore.
7332 * The silc_server_notify now checks on JOIN notify whether the joining
7333 client is one of locally connected or global. If it is global then
7334 the channel has now global users on the channel and that is marked
7335 to the channel entry. Also, it now saves the global client to
7336 global list who is joining and JOINs it to the channel. This is
7337 for normal server, that is.
7339 Changed silc_server_send_notify_on_channel,
7340 silc_server_packet_relay_to_channel and
7341 silc_server_packet_send_to_channel check if we are normal server
7342 and client has router set (ie. global client) do not send the
7343 message to that client, as it is already routed to our router.
7345 * Implemented LEAVE notify type handling in silc_server_notify
7348 * Tested LEAVE command in router environment successfully. Tested
7349 with two routers, two servers and two clients.
7353 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
7355 * Implemented SIGNOFF notify type handling in silc_server_notify
7358 * silc_server_remove_id now removes the client entry from all channels
7359 it has joined and thusly sends SIGNOFF notify type.
7361 * Rewrote the NAMES list generation in server by removing two excess
7362 loops. The lists are created now inside one loop.
7364 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7366 * silc_server_remove_channel_user checks now also global list
7367 for channel and client.
7369 * silc_server_new_channel_user checks now both local and global
7370 list for channel and client. Fixed a bug in client id decoding.
7371 Used to decode wrong buffer.
7373 * silc_server_channel_message checks now both local and global
7374 list for channel entry.
7376 * Tested channel joining (hence JOIN) in router environment
7377 successfully. Tested with two routers, two servers and two
7380 * Tested channel message sending in router environment successfully.
7382 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7384 * Added silc_server_save_channel_key into server.[ch] to save the
7385 received channel key in Channel Key payload processing. It is
7386 also used in JOIN command reply handling.
7388 Equivalent function silc_client_save_channel_key added into
7389 client.[ch] into client library.
7391 * Changed JOIN command reply to send information whether the channel
7392 was created or not (is existing already) and the channel key
7393 payload. Changed protocol specs accordingly.
7395 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
7396 the request was sent by ID and not by nickname. Crashed on
7399 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7401 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
7402 now correctly save the received data.
7404 * silc_server_free_sock_user_data now notifies routers in the
7405 network about entities leaving the network.
7407 At the same time implemented functions silc_server_remove_id
7408 and silc_server_send_remove_id to receive and send REMOVE_ID
7409 packets. The packet is used to notify routers in the network
7410 about leaving entities. The ID removed will become invalid in
7413 * Added function silc_idlist_del_server into server. Removes and
7414 free's server entry from ID list.
7416 * silc_server_private_message function now checks, if we are router,
7417 that the destination ID really is valid ID, naturally.
7419 * In router when NEW_ID packet is received (for new client) the
7420 hash of the Client ID is saved in the ID Cache but the
7421 client->nickname is set to NULL, instead of putting the hash
7424 IDENTIFY command now also checks that client->nickname must be
7425 valid. If it is not if will request the data from the server who
7426 owns the client. Added new function
7427 silc_server_command_identify_check.
7429 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
7430 to set the command to already allocated Command Payload.
7432 * Tested private message sending in router environment with two
7433 routers, two servers and two clients. Fixed minor bugs and now
7436 * Fixed segfault from client's NAMES command. Used to crash if
7439 * Forwarded packets must not be routed even if it is not destined
7440 to the receiver. Changed server code comply with this.
7442 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7444 * Added `require_reverse_mapping' boolean value to ServerParams
7445 structure. If TRUE (not default) the server will require that
7446 the connecting host has fully qualified domain name.
7448 If the reverse mapping is not required and hostname could not be
7449 found the IP address is used as hostname.
7451 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7453 * Implemented version string checking to both client and server.
7454 The check is incomplete currently due to the abnormal version
7455 strings used in development version of SILC.
7457 * Changed all command functions in server to use the new
7460 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7462 * Changed char *data to unsigned char *data in ID Cache system to
7463 support binary data as ID Cache data. Changed code to support
7464 binary data in lib/silccore/idcache.c.
7466 * Renamed silc_server_packet_relay_command_reply to
7467 silc_server_command_reply as it is normal packet receiving
7468 function. Rewrote the function to accept command replys for
7469 servers and not only for clients.
7471 * Mark remote router always as registered server if we are connecting
7472 to it. Otherwise, commands sent by the router to us are ignored.
7474 * All ID List find routines now returns the ID Cache Entry pointer
7475 as well if requested.
7477 * WHOIS command works now in router environment, tested with two
7478 routers, two servers and two clients.
7480 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
7481 in router environment (as it is almost equivalent to WHOIS) but
7482 hasn't been tested thoroughly. Added new functions:
7484 silc_server_command_identify_parse
7485 silc_server_command_identify_send_reply
7486 silc_server_command_identify_from_client
7487 silc_server_command_identify_from_server
7489 * Disabled route cache adding because adding two different ID's with
7490 same IP replaces the old cache entry thus giving wrong route.
7491 The entry->router->connection is always the fastest route anyway
7492 so route cache may not be needed. Of course, new routes maybe
7493 established after receiving the ID when the entry->router->connection
7494 might not be anymore the most optimal.
7496 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7498 * Add route cache for received ID for fast routing.
7500 * Added silc_server_packet_route to route received packet on router
7501 that is not destined to us.
7503 * Renamed silc_server_get_route to silc_server_route_get.
7505 * Added id_string and id_string_len fields into SilcServer to
7506 include encoded ServerID for fast comparing without excess
7507 encoding of the ID's.
7509 * Cleaned up WHOIS command on server side. Added following static
7512 silc_server_command_whois_parse
7513 silc_server_command_whois_check
7514 silc_server_command_whois_send_reply
7515 silc_server_command_whois_from_client
7516 silc_server_command_whois_from_server
7518 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
7519 arguments in command replies. All command functions should be
7520 updated to use this macro.
7522 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7524 * Minor typo fixes on command reply handling on server.
7526 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7528 * Added silc_server_command_add_to_channel internal routine to add
7529 the client to the channel after router has created the channel and
7530 sent command reply to the server.
7532 * Added generic silc_server_send_command to send any command from
7535 * Use static buffer with ID rendering instead of duplicating data.
7537 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7539 * Fixed a channel user mode bug when joining to a channel server gave
7540 everybody channel founder rights, oops.
7542 * We mark ourselves as the router of the incoming server connection
7543 if we are router ourselves. This way we can check in some packet
7544 sending functions whether it is locally connected server. For
7545 incoming router connections we put NULL.
7547 * For router sending packets locally means now always sending the
7548 packet cell wide; to local clients and local servers. For normal
7549 server sending packet locally means sending it to only local
7552 * Fixed the JOIN command to really work in router environment. If the
7553 channel is created it is always created by the router. Router is
7554 also responsible of making the initial joining to the channel,
7555 sending JOIN notify to the sending server and distributing
7556 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
7557 does not exist server doesn't do anything else but forward the
7558 command to the router which performs everything.
7560 * Added silc_server_send_channel_key function to send the Channel Key
7563 * Added silc_server_create_channel_key to create new channel key. The
7564 channel key is now re-generated everytime someone joins or leaves
7565 a channel, as protocol dictates. Note: channel->key_len is the
7568 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7570 * Splitted server.[ch] finally. Created now packet_send.[ch] and
7571 packet_receive.[ch] to separate packet sending and receiving
7572 routines. The server.[ch] now includes everything else including
7573 actual packet processing (writing and reading data) and other
7576 Renamed silc_server_private_message_send_internal to
7577 silc_server_send_private_message. The routine is still though
7578 used only to relay private messages as server does not send
7579 private messages itself.
7581 Renamed silc_server_new_channel to silc_server_create_new_channel
7582 and added new function sicl_server_new_channel that handles the
7583 incoming New Channel packet. Added also new sending function
7584 silc_server_send_new_channel to send New Channel Payload.
7586 * Added new function silc_server_notify to process incoming notify
7587 packet to the server/router. Server may then relay the notify
7588 to clients if needed.
7590 * Added new function silc_server_new_channel_user to process incoming
7591 New Channel User packet. Router will redistribute the packet and
7592 send JOIN notify to its local clients and locally connected servers
7593 if needed. Normal server will send JOIN notify to its local client
7594 on same channel when received this packet. Added also corresponding
7595 sending function silc_server_send_new_channel_user to sent the
7598 * Added boolean route argument to send_notif_to_channel and
7599 packet_send_to_channel functions to attempt to route the packet
7600 if it is TRUE and send only locally if it is FALSE.
7602 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7604 * silc_server_replace_id now broadcasts the received replace ID
7605 packet if it is not broadcast packet already. The router must
7606 broadcast to inform other routers about changed ID.
7608 * Added backpointer to server's router into SilcServer context in
7609 silcd/server_internal.h.
7611 * Fixed silc_server_packet_broadcast to send correct broadcast
7614 * The channel key is now distributed to the local client as soon
7615 as it is received from the router (in router environment) so that
7616 no other packet may be sent for the channel until client has
7619 * silc_server_remove_channel_user now broadcasts the received
7620 Remove Channel User packet if it is not broadcast packet already.
7621 The router must broadcast to inform other routers about removed
7624 * Added users field into SilcPacketContext that is a reference count
7625 of the context. One can increase the reference count by calling
7626 silc_packet_context_dup which is now changed to just increase the
7627 reference count instead of duplicating the data. The reference
7628 count is decresed by calling silc_packet_context_free that will
7629 free the data after the reference count hits zero.
7631 For now on the packet context and everything allocated into it
7632 (including the raw packet from network) must be freed by calling
7633 the new silc_packet_context_free function. Added also new function
7634 silc_packet_context_alloc that must be used now to allocate the
7635 context. This also means that if a routine is asynchronous from
7636 silc_[client/server]_packet_parse_type the packet context must
7637 be duplicated by calling silc_packet_context_dup. Otherwise it
7638 gets free'd after silc_[client/server]_packet_parse_type returns.
7639 Also, one must remember that if packet is duplicated then its
7640 reference count must be decresed by calling the free function as
7641 many times as it was duplicated.
7643 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7644 from both client and server.
7646 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7648 * Made joining to a channel working in router environment.
7650 * Cleaned up JOIN command on server side and create function
7651 silc_server_command_join_channel internal routine to make the
7654 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7656 * Changed silc_command_pending list to SilcDList. Also, added
7657 `ident' field to SilcServerCommandPending structure to identify
7658 the reply and to call correct callback.
7660 Added silc_server_command_pending_check function to replace the
7661 corresnponding macro. The silc_command_pending list is not
7664 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7665 to set identifier to previously allocated Command Payload. It
7666 is used to set identifier for command when resending Command
7669 * Added silc_command_payload_encode_payload to encode Command
7670 Payload buffer from SilcCommandPayload structure.
7672 * Added silc_argument_payload_encode_payload to encode Argument
7673 payload buffer from SilcArgumentPayload structure.
7675 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7677 * Changed WHOIS command to support router connection on server side.
7678 The whois request is always sent to router unless the server is
7679 standalone server. After server has received the reply from the
7680 router will it send the reply to the client.
7682 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7683 broadcast received broadcast packet. The function is used only
7684 by router. The broadcast packet is always sent to the router's
7687 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7688 render given ID to printable string, for log files for example.
7690 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7692 * Made basic router to router connections working. At least they
7693 can now connect to each other but nothing really works the way
7694 they are supposed - yet.
7696 * Added new initiator token to RouterConnection configuration
7697 file in silcd/serverconfig.[ch]. It is used to tell whether we
7698 are the initiator to the remote router or whether we'll expect
7699 the other end to connect.
7701 * Moved registering of listener task to silc_server_init, hence
7702 the server starts listenning as soon as it is run, even if it
7703 does not have connections to other routers. Let's see how well
7706 * Changed default connection retry timeouts for more suitable in
7709 * Removed cipher and such arguments from silc_idlist_add_client
7710 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7711 Added new function silc_idlist_add_data to add the keys and stuff
7714 * Added SilcIDListData structure and added it to SilcClientEntry
7715 and SilcServerEntry as their first field in the structure. This
7716 way we can explicitly cast the ID entries to the SilcIDListData
7717 structure and get common data for the entries. In past, we had
7718 to first check what type of connection it is and then cast it to
7719 correct ID entry type. Now, we can directly cast the opaque
7720 pointer to the SilcIDListData (no matter what ID entry it actually
7721 is) and get the data needed.
7723 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7725 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7726 in some circumstances even if threre were timeout tasks, though not
7727 IO tasks, but tasks anyway. Now fixed.
7729 * Defined SilcServerConnection structure to hold connection specific
7730 stuff about directly connected servers and routers. The definition
7731 is currently in silcd/server_internal.h. I thought about having
7732 a bit more important role fro this struct but for now it is used
7733 only when connecting to other server (or router actually).
7735 * Added connecting retry support in server when connecting to
7736 router(s). The retry feature implement exponential backoff
7737 algorithm. Also, added SilcServerParams structure to hold default
7738 parameters for server. For now, it include these retry settings
7739 and are hard coded. After server is moded to be as Silc Server
7740 Library this structure will be more important.
7742 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7744 * Changed client librarys channel->clients table to SilcList and
7745 changed code accordingly.
7747 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7749 * Changed client's channel table to SilcList and changed code
7750 accordingly. Also changed SilcChannelClientEntry to include back-
7751 pointer to the channel so that client entry can use that structure
7752 as list as well and we have fast cross-reference to the channel.
7753 This change dramatically decreased the complexity of channel
7754 handling with client entry and vice versa (removed one extra
7755 loop when searching for channel entry from many functions).
7757 * Changed server->sim from table to SilcDList and changed code
7760 * NAMES command can now be used from user interface. It will show
7761 the user list on the channel, neatly.
7763 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7764 Code now saves realname of the user if it becomes available.
7766 * Renamed configure.in to configure.in.pre and made ./prepare
7767 script to automatically add correct version string to
7768 configure.in which it creates from configure.in.pre.
7770 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7772 * NAMES command reply now shows users mode with the nickname when
7775 * Moved silc_client_ch[u]mode[_char] functions from
7776 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7777 place sucks, they are utility functions and should be in some
7780 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7782 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7785 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7789 * Added TRQ (efficient deque and list library) into lib/trq. This is
7790 a very good list library that is currently used in the SILC. Defined
7791 SilcList API over the library because I didn't like the API very
7792 much. See lib/trq/silclist.h for the API and examples of how to
7793 use the API. Fixed various places in the code to use the new
7794 SilcList API. The SilcList is meant for lists that has a structure
7795 already defined as a list. It is not suitable to add just some
7796 context to the list (in TRQ, the context is the list actually).
7798 So, I defined SilcDList that can be used for the purpose where
7799 predefined list structure does not exit. This can be used as
7800 such list. Now some context just can be added to the SilcDList.
7801 Currently this list is not used in the SILC just yet, though there
7802 are a lot places where this can replace dynamically allocated
7803 tables and I will fix these places, later, to use SilcDList.
7804 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7805 and use TRQ internally).
7807 Also fixed some annoying warning messages that the original TRQ
7808 code generated. Also minor changes to TRQ's Makefile.in.
7810 * Added support for querying by Client ID to both WHOIS and
7811 IDENTIFY commands into server, as required by the protocol.
7813 * Removed method function pointers from SilcBuffer structure. They
7814 weren't used to anything and just increased the context size for
7815 no good reason. This change also made silc_buffer_alloc and
7816 silc_buffer_free functions inline functions.
7818 * Disabled command flooding detection support until it's fixed so
7819 that it accepts commands in but does not execute them more than once
7822 * Added silc_net_localhost(), to return local hostname, into
7823 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7824 that must be initialized before calling silc_client_init.
7826 * Added new function: silc_server_send_notify_on_channels to send
7827 notify messages to all channels client has joined. It is assured
7828 that the message is sent only once per client.
7830 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7831 lib/silcutil/silcutil.[ch] as silc_format function. The new
7832 function is generic and is used by server as well, not only by
7833 the logging routines.
7835 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7836 the provided version string was not acceptable. Added new function:
7837 silc_ske_check_version into lib/silcske/silcske.h. The function
7838 must be implemented by the application (client or server) and it
7839 does not reside in the SKE library. The function checks the version
7840 string remote end sent.
7842 * Added back pointers (to opaque context and to SilcSocketConnection)
7843 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7845 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7846 duplicate packet context structure.
7848 * Changed `notify' client operation to send same arguments as client
7849 receives from server except for ID's. ID's are mapped to correct
7850 ID entry and that is returned. Also, if channel entry is not sent
7851 by server but the notify is for channel the channel entry is sent
7852 to application (otherwise application doesn't know that it is for
7853 channel (library gets it from packet's Destination ID)).
7855 * Added silc_client_remove_from_channels into client library to
7856 remove a client from all channels it has joined to. Used when
7857 received SIGNOFF notify from server. Added also new function
7858 silc_client_replace_from_channels to replace old ID entry with
7859 new ID entry on all channels. Used when received NICK_CHANGE
7862 * Fixed ID Cache list handling in silc_idlist_get_client in
7863 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7864 to get (or query) client by ID.
7866 * Updated TODO list.
7868 * Added connection authentication status message defined by the
7869 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7870 support for these into the code in client and server side.
7872 * Added generic function silc_client_send_command to send any command
7873 with variable argument list. Application should use this function
7874 to send commands if the command functions provided by the library
7875 does not suite for the application's user interface needs.
7877 * Added new `failure' client operation. Application is notified about
7878 received failure packet if client is executing a protocol. In this
7879 case the protocol's execution has failed.
7881 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7882 is required by the protocol.
7884 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7885 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7888 * Added status flag to SilcSKE object to indicate realtime status
7889 of the SKE protocol.
7891 * Application receives now exactly same command reply arguments as
7892 the library receives from server. However, if ID is received the
7893 corresponding ID entry is returned to the application (eg. Client
7894 ID is mapped to correct SilcClientEntry entry and that is returned).
7895 Changed command_reply client operation due to this change.
7897 * Changed all ID's in commands and in command replys as ID Payloads.
7898 Change affected both client and server side codes.
7900 All ID's sent in SILC network (with execption of ID's in SILC
7901 Packet header) are sent in ID Payload to support variable length
7904 * Server now notifies nick changes and notifies all clients on
7905 the channels about the new nickname (about the new Client ID,
7908 * Implemented CMODE command to change channel modes. Supports all
7909 channel modes defined by the protocol specs except ban and invite
7910 lists. (Also, private channel key mode is supported but support for
7911 setting private channel key in client is missing, thus, this mode
7912 has no effect on client side (except that server requires that the
7913 client uses private channel key and normal channel traffic does not
7916 Also, invite mode works per se, but INVITE command does not work
7917 yet correctly, so you can set channel as invite only channel but
7918 inviting clients to the channel does not work (it is yet to be
7919 thought what's the best way to do it).
7921 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7922 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7923 Implemented CUMODE command to change user's mode on the channel.
7924 Supports all modes defined by the protocol specs.
7926 * Added NAMES command reply to return users modes on the channel.
7928 * Removed unnecessary and slow ciphers from lib/silccrypt.
7930 * Set SO_KEEPALIVE option to connection sockets by default.
7932 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7934 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7935 redefined the Notify Payload into protocol specs.
7937 * Added silc_id_payload_parse_id to get ID directly from raw
7940 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7942 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7943 accept searching by Client ID as well.
7945 * Added support for LEAVE and SIGNOFF notify types in client library.
7947 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7948 to parse ID Payload from raw data.
7950 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7952 * Added flags parameter into silc_ske_assemble_security_properties
7953 function in lib/silcske/silcske.[ch].
7955 * Changed notify client operation to fit better for notify messages
7956 sent by server. The notify payload received from server is now
7957 passed to the application (after parsing it to SilcNotifyPayload).
7958 It is application's responsibility to retrieve the arguments
7959 from the payload and show the message the way it wants. The message
7960 sent by server is implementation specific.
7962 * Changed public keys to comply with the protocol specification.
7963 Old public keys are not supported anymore and are not compatible.
7965 * Removed nickname from Channel Payload as the latest draft removed
7966 it. The client must resolve the nickname from the NAMES command
7967 reply received when it joined the channel.
7969 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7971 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7973 * Fixed some errors in protocol specification drafts.
7975 * Created lib/silccore/silcnotify.c to implement Notify Payload
7976 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7977 generic payloads described by protocol specifications. The file
7978 includes implementations for ID Payload and Argument Payload.
7980 * Changed Command Payload implementation to use the new Argument
7981 Payload. Changed command_xxxx_payload to command_payload_xxxx
7982 to comply with SILC coding conventions.
7984 * Added suppport for Argument Payload handling in Notify Payload
7985 implementation as protocol requires it. Added the new support
7986 into server and client lib as well.
7988 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7990 * Added support for multiple nicknames on same channel. [n] is
7991 added locally to the nickname if there are more than one same
7992 nicknames on the channel.
7994 * Server now sends all nicknames that matched WHOIS request.
7995 Client also shows the list received from server.
7997 * Added TOPIC command to client side. User can now set and show
7998 current topic on channel.
8000 * Added MOTD command to client and server. Also, server sends the
8001 motd when client connects to the server.
8003 * Changed version strings to comply ISO 8601.
8005 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8007 * Fixed protocol error handling in client library. It should now
8008 cope even if the SKE fails for some reason.
8010 * Made new protocol specification drafts for submitting to IETF.
8012 * Implemented TOPIC command to server in silcd/command.c.
8014 * Added two new notify types into lib/silccore/silcnotify.h:
8015 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
8016 notify nickname change and topic setting/change on a channel.
8018 * API change of command_reply operation in client library. The
8019 application gets now the status type received from server as well.
8021 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8023 * Removed the function just added to lib/silcutil/silcschedule.[ch].
8025 * Cras fixed and optimized the packet handling even further and
8026 it should work now. Minor change to the prototype of function
8027 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
8029 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8031 * Added new function into lib/silcutil/silcschedule.[ch]:
8032 silc_schedule_with_fd to select() a specified fd. The function
8033 returns after timeout expires or data arrives or goes. The
8034 function is used by packet routines to wait that all data is
8035 received from network.
8037 * Fixed data reading from network in lib/silccore/silcpacket.c.
8038 The code now assures that all data is read from the fd and then
8039 continues packet processing. This was a bug fix since the code
8040 used to drop some data in some circumstances.
8042 * Added new function into lib/silcclient/client.[ch]:
8043 silc_client_start_key_exchange to start key exchange after
8044 connection has been established to server. The code internally
8045 now uses this funtion but its main purpose was to provide it
8046 for applications that perform their own connecting. After
8047 application has created a connection it merely calls this
8048 function to start the key exchange between client and server.
8049 The library takes care of everything else after that.
8051 Updated also lib/silcclient/README to explain the usage of
8054 * Do not send to application information that connection has
8055 been established. Application gets notified it by connect
8058 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8060 * Applied cras's patch to add silc_schedule_one function. The
8061 function runs scheduler once and returns.
8063 * Fixed the scheduler after cras messed it up. The timeout
8064 handling works now as it's supposed to work.
8066 * Added into lib/silccore/ silcnotify.h to include notify
8067 message types support. Changed silc_server_send_notify*
8068 functions, in server.[ch], to support those new notify types.
8069 Added the support for the notify types into client library,
8070 as well. Added new notify client operation into ops.h in
8073 * Changed silc_server_packet_send_to_channel to send normal
8074 packets instead of just channel message packets. The function
8075 is now used to send the notify packets to channels. It is not
8076 used to send channel message packets anymore, as server never
8079 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
8080 va_arg()s as it seems to require it nowadays. I guess, if SILC
8081 is compiled with older va_arg() the new code should work anyway.
8083 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8085 * Splitted core library. Core library (lib/silccore) includes
8086 now only SILC protocol specific core (and common) components.
8087 Created new utility library (lib/silcutil) that includes more
8088 generic purpose stuff. The stuff for util library was taken
8089 from the old core library. This was minor and easy split.
8091 * Created SILC Client Library (lib/silcclient) that includes
8092 implementation of the SILC client without user interface. This
8093 was major move from silc/ directory. The code has been changed
8094 so that it is transparent towards the user interface. The
8095 silc/ directory includes now the same user interface as before
8096 and it uses the new client library. Read lib/silcclient/README.
8097 Basicly, the client library performs everything else related
8098 to SILC except user interface handling. Also, configuration
8099 files are considered to be part of user interface and library
8100 does not handle them.
8102 This change also changed a lot of structures, function naming etc.
8103 Most important change was that SilcClientWindow object was
8104 renamed to SilcClientConnection in the client library. Created
8105 also new file lib/silcclient/ops.h. Also added new files
8106 silc/local_command.[ch] and silc/client_ops.[ch].
8108 All these changes were made to make it easier for user interface
8109 designers to create what ever user interface for the SILC client
8112 It is also expected that the server will be moved to lib
8113 directory as well and SILC Server Library will be created;
8114 sometimes in the future.
8116 * Removed Local commands from lib/silccore/silccommand.h as
8117 they are application specific and new client library does not
8118 handle any of those anymore.
8120 * Several functions moved to lib/silcutil/silcutilc.[ch] from
8121 old client implementation in silc/.
8123 * Added support for callback functions in SILC_LOG_* macros.
8124 Application can now set its own callbacks that will be called
8125 instead of using the default functions that will always print
8126 the debug messages to stderr (or stdout). Also, debugging can
8127 now be disabled by setting silc_debug to FALSE and re-enabled by
8128 setting it to TRUE. Note, that logging will still work even
8129 if debugging is disabled.
8131 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
8132 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
8133 silc_log_reset_debug_callbacks.
8135 * To enable debugging in silc client one must give now -d
8136 option on command line.
8138 * Changed silc_schedule_init to automatically allocate task queues
8139 if they are not allocated before calling it.
8141 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8143 * Added GMP 3.1 into math library.
8145 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8147 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
8148 a channel in SILC network. The packet is used by servers and
8149 routers to notify other routers that user has left a channel.
8150 This little feature was missing until now. Added the feature
8151 to protocol specification as well.
8153 Added functions: silc_server_send_remove_channel_user and
8154 silc_server_remove_channel_user into server.[ch].
8156 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
8157 lib/silccore/silcpacket.h. However, they are not implemented
8160 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8162 * Fixed joining to a channel and sending channel messages
8163 between server and router. The channel message sending should
8164 now work inside a cell.
8166 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8168 * Fixed the private message sending between server and router.
8169 The private message sending should now work inside a cell.
8171 * Added silc_server_replace_id into server.[ch] to replace
8172 existing ID in the SILC network.
8174 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
8175 and silc_idlist_replace_server_id into idlist.[ch] in server.
8177 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8179 * Fixed the server to server connections. Server can again now
8180 connect to router. Router to router connections probably does
8183 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8185 * Added dynamic protocol registering support. Now protocols can
8186 registered and unregistered on the fly. Patch by cras.
8188 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8190 * Added lib/contrib directory to hold routines that some platforms
8191 don't have but are needed by SILC.
8193 * Added getopt.c, getopt1.c and getopt.h from GNU C library
8194 into lin/contrib to provide getopt() and getopt_long() for
8195 those who don't have it.
8197 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8199 * Added AWAY command to client. When away message is set and
8200 client receives a private message packet the client automatically
8201 replies to the sender with the away message.
8203 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
8204 bug seemed to be the cause of recent problems when compiling
8207 * Added version detection support to SKE protocol specification
8208 and added the new changes to the SKE implementation as well.
8209 There were other minor changes in the SKE protocol as well.
8211 Many changes in lib/silcske/silcske.[ch] and in
8212 lib/silcske/payload.[ch].
8214 * Added ^U functionality, clear input line. Patch from cras.
8216 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8218 * Mainly small bugfixes on core library. Fixed some debugging
8219 logging and buffer overflow in silclog.c.
8221 * Updated config.sub and config.guess on the distribution tree.
8223 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8225 * Added command lagging support in server. Client may execute
8226 commands now only once in two seconds.
8228 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8230 * Optimized packet reception. MAC computation and checking is now
8231 also more optimized. A lot previously duplicated code is now
8232 used as generic by both client and server.
8234 * Fixed key pair generation in clientutil.c
8236 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8238 * Added into lib/silccore/silcbufutil.[ch] new function;
8239 silc_buffer_realloc.
8241 * Moved generic packet sending/encryption functions to
8242 lib/silccore/silcpacket.[ch] from client and server. Some
8243 rewriting of the functions.
8245 * Moved all generic packet reception/decryption functions to
8246 lib/silccore/silcpacket.[ch] from client and server. The
8247 packet processing is now much cleaner in both client and server.
8248 These were major changes in both client and server.
8250 * Created many common functions in server to do packet sending.
8251 Previously code were duplicated a lot, this has been removed
8254 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8256 * Rewrote major parts of the ID cache system. Don't know
8257 whether it is better now or not but at least the API is more
8260 * Major rewrite on ID cache stuff on client because of the ID
8261 cache API changes. Added idlist.c to client.
8263 * Also major rewrite on ID cache stuff on server as well.
8264 Major rewrite of idlist.[ch]. SilcXXXList's are now named
8265 SilcXXXEntry's. We won't keep anymore idlist specific pointers
8266 in hand, instead they are all put into the ID cache system now.
8267 All server_idlist_* routines uses ID cache now instead of
8268 traversing its own lists (those lists does not exist anymore).
8269 SilcIDList though still exists. Also, SilcXXXEntry's are
8272 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8274 * Finally made the SKE implementation compliant to the protocol
8275 specification. All mp integers are now binary encoded as
8276 opposed being HEX encoded.
8278 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
8281 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
8282 functions: silc_[encode/decode]_pem. Also added function
8283 silc_encode_pem_file to PEM encode with newlines ('\n') for
8286 * SILC public keys are now encoded either PEM or binary. Same
8287 option is for private keys as well. By default private keys
8288 are binary encoded and public keys PEM encoded. Silly HEX
8289 encoding were removed.
8291 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
8292 function to create fingerprints.
8294 * Fixed a bug in SHA1; does not change the original data anymore.
8296 * Partly implemented INFO command on client and server side.
8297 Fixed CLEAR command. Changes to SERVER command; show current
8298 server(s) when giving command without arguments. Added
8299 VERSION command to client.
8301 * Added check to server that unregistered connections cannot
8302 execute commands (unless it is specificly allowed).
8304 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8306 * Fixed screen refresh.
8308 * Fixed channel joining bug from client. On some circumstances
8309 client tried to join to a channel it had already joined.
8311 * Added public key verification process into client's protocol.c.
8312 The client now verifies the public key from user and saves
8313 it into ~./silc/serverkeys/ directory.
8315 Added into: clientutil.[ch]: silc_client_verify_server_key.
8317 * Changed SKE protocol's silc_ske_initiator_finish function
8318 to accept callback function that verifies the received public
8319 key. Removed old silc_ske_verify_public_key function.
8321 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8323 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
8324 silc_pkcs_private_key[_data]_set.
8326 * Made the password and public authentication more cleaner in
8327 server's protocol.c.
8329 * Removed historic and obsolete protocol `channel_auth' from
8330 both client and server.
8332 * Removed wrong way of sending command status messages from
8333 server to client in server's command.c. The old way violated
8334 protocol specification.
8336 Changes to silccore/silccommand.[ch]: removed
8337 silc_command_encode_status_payload -> not needed anymore,
8338 changed silc_command_encode_payload_va to accept extra
8339 argument on variable argument list. The argument type must
8340 now be provided to the function. Also, added new function:
8341 silc_command_encode_reply_payload_va which is same as
8342 normal command_encode_payload_va except command status type
8343 is provided as extra argument.
8345 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8347 * Added ~./silc directory handling. The directory includes the
8348 public and private keys for the client.
8350 Added silc_client_check_silc_dir, silc_client_create_identifier
8351 and silc_client_load_keys.
8353 * Implemented SILC protocol compliant public key. Added public
8354 and private key saving to and loading from files.
8356 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
8357 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
8358 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
8359 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
8360 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
8362 Implemented: silc_pkcs_save_[public/private]_key[_data] and
8363 silc_pkcs_load_[public/private]_key.
8365 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8367 * Added silc_server_get_route (route.[ch]) to get connection
8368 data for the fastest route for given ID.
8370 * Implemented INVITE command on client and server. The command
8371 were re-defined in the SILC Protocol Specification and the
8372 implementation now complies with the specification.
8374 * Implemented PING command on client and server.
8376 * Implemented NAMES command on client and server. The server side
8377 supports currently only normal server not router server yet.
8378 Some changes to NAMES definition in SILC protocol specification.
8380 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8382 * Implemented LEAVE command on client and server.
8384 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
8385 again. This change was made to the protocol as well. Server
8386 should not violate the protocol specification anymore.
8388 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8390 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
8391 was tested. SOCKS4 was not but should work anyway.
