505 * Fixed a bug in server where sending unknown command crashes
506 the server. Affected file silcd/command.c.
508 Wed Apr 3 09:57:47 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
510 * Added SILC_PROTOCOLVERSION macro to check protocol version
511 of a socket connection. The affected file is
512 lib/silcutil/silcsockconn.h.
514 * Added better error logging in rekey protocol. Affected file
517 * Do not check public key types in SKE during rekey. Affected
518 file lib/silcske/payload.c.
520 * Fixed the rekey protocol with PFS, which was totally broken.
521 Affected file silcd/protocol.c.
523 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
525 * Some client implementations quit network by doing first LEAVE
526 and then immediately SIGNOFF (like Bombyx). We now do check
527 after a short time after LEAVE notify and check whether the
528 client is still valid after LEAVE, and if not we remove it from
529 cache. Affected file is lib/silcclient/client_notify.c.
531 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
533 * Merged version 1.1.4 of zlib. Even if it not currently in use,
534 it's good not to have security holes here.
536 * Fixed a negative refcount situtuation for the config context.
537 Affected file is silcd/serverconfig.c.
539 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
541 * ROBOdoc documented lib/silcutil/silcutil.h.
543 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
545 * Optimized even more the SilcPacketContext structure. Now
546 totally saved 16 bytes of memory per context after optimization.
547 Affected files are lib/silccore/silcpacket.[ch].
549 * Made strict checks for valid SILC IDs. Affected file is
550 lib/silccore/silcid.c.
552 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
554 * Changed the object argument for silc_cipher_register,
555 silc_hash_register, silc_hmac_register and silc_pkcs_register
556 to const. Affected files are lib/silccrypt/silccipher.[ch],
557 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
559 * Changed the silc_get_username and silc_get_real_name to
560 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
562 * Fixed the Irssi SILC Client to use the silc_get_username and
563 silc_get_real_name insted of glib routines since the glib
564 routines only corrupt stack. Fixes the Irssi SILC to work in
565 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
567 * Fixed the Irssi to not use g_get_home_dir since it crashes
568 or returns garbage on cygwin and corrupts stack. Added function
569 get_home_dir to Irssi routines. Affected files are
570 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
572 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
574 * Made some structure optimizations. SFTP memory FS MemFSEntry
575 entry structure. Optimized SilcTask structure. Optimized
576 SilcPacketContext structure.
578 Affected files lib/silcsftp/sftp_fs_memory.c,
579 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
581 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
583 * And yet again reverted back the config thing since Johnny
584 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
587 * Fixed memory leaks from config object. Affected files are
588 silcd/serverconfig.[ch].
590 * Added support for adding new connections to the server in rehash.
591 After rehash they take effect.
593 Added support for changing the maximum allowed connections in
594 rehash. The number can grow but going smaller is not supported.
596 Added function silc_server_num_sockets_by_remote to the
597 silcd/server_util.[ch].
599 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
601 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
603 * Added preliminary checking during config parsing for a valid
604 public/private key and removed further checks in the code.
605 Affected files are silcd/serverconfig.[ch], server.c.
607 * Moved functions silc_server_drop() and silc_server_daemonise()
608 from server.c to silcd.c since they are stricly related to
609 the application activity.
611 * Reverted a small part of the automatic ref/unref since
612 it caused a double unref in some situations. Affected
613 files are silcd/silcd.[ch], server.c, serverconfig.c.
615 * Added some .cvsignore files in the lib directory.
617 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
619 * Fixed silc_net_gethostbyaddr to correctly resolve by
620 address. Affected file lib/silcutil/silcnet.c.
622 * Fixed the notify relaying to client. The HMAC to be used
623 with relayed packets ws wrong and caused decryption failure
624 at the client end. Affected file is silcd/packet_receive.c.
626 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
628 * Created new branch silc_protocol_1_0_branch.
630 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
632 * Changed the silc_server_config_* routines to be SilcServer
633 independent. They are now officially application specific code
634 and not part of generic server implementation. Affected files
635 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
637 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
639 * Added automatic referencing of config context in the
640 silc_server_config_alloc, and automatic unreferencing in the
641 silc_server_config_destroy. Affected files are
642 silcd/serverconfig.[ch], silcd/silcd.c.
644 * Fixed the silc_log_quick handling in the logging routines.
645 It didn't log quickly when it was TRUE. Affected file is
646 lib/silcutil/silclog.c. Also the flush delay was set even
647 if it was 0 in config file. Affected file is
648 silcd/serverconfig.c.
650 * Added support for changing key pair of the server in rehash.
651 Affected file silcd/server.c.
653 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
655 * Fixed the TOPIC_SET notify to not cras. It changed the topic
656 too early, before getting the channel entry. Affected file
657 is silcd/packet_receive.c.
659 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
661 * Added functions silc_server_config_[ref/unref], these are used
662 to prevent that the config object is destroyed.
664 No longer directly affect global variables silc_log_quick and
665 silc_log_delay, they are first cached inside the config object
666 and then applied with silc_server_config_setlogfiles().
668 silc_server_config_set_defaults() is now internal to
669 serverconfig.c, there are no reasons to show this internal stuff
672 Affected files are silcd/serverconfig.[ch].
674 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
675 fprintf's to stderr, since some code may be executed again after
676 the server went into the background. Affected files are
679 * Added rehash support. Added function silc_server_rehash() that
680 will perform all the basic tasks of the rehashing procedure.
682 * Added command line option `-x, --hexdump'. This will enable the
683 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
684 The option `--hexdump' implies `--debug'.
686 * Fixed a bad bug in the logging APIs (silcutil library) where
687 the application would crash after calling silc_log_reset_all().
689 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
691 * Fixed the KICKED notify handling in client library to
692 correctly remove the channel and all entries from the
693 channel when I was kicked. This bug crashed the client.
695 Fixed yet another but in KICKED notify handling to remove
696 the kicked client correctly from the channel.
698 Affected file is lib/silcclient/client_notify.c.
700 * Fixed a minor bug in looking up correct client entry
701 in KICKED notify in server. Affected file is
702 silcd/packet_receive.c.
704 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
705 sources correctly to distribution. Fixes --with-gmp option.
707 * Removed the manual rehashing from ID Cache, and changed it
708 to use the SILC Hash Table's auto rehash feature. Affected
709 file is lib/silccore/silcidcache.c.
711 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
713 * Fixed a bug in the silc_client_nickname_format function that
714 handles the multiple same nickname formatting. Two clients
715 with same nickname caused problems after the first one left
716 and rejoined. It didn't format the nickname correctly.
717 Affected file is lib/silcclient/idlist.c.
719 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
721 * Don't change the topic if olod topic is same as new one.
722 Affected file is silcd/packet_receive.c.
724 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
726 * Added cross-reference support to the SILC Documentation
727 generator. All types across all HTML files are now cross-
728 referenced. Affected files util/robodoc/generator.c and
729 scripts/silcdoc/silcdoc.
731 * Added file lib/silcutil/silctypes.h to include all the
732 arithmetic type definitions and some macros. Removed
733 includes/bitmove.h and moved macros to silctypes.h.
735 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
737 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
739 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
741 * Added `type' argument to silc_id_payload_parse_id function which
742 now returns the type of the ID to the sent pointer. Affected
743 file is lib/silccore/silcid.[ch].
745 * Added check for CMODE_CHANGE notify type that mode change is
746 allowed by the sender. Affected file silcd/packet_receive.c.
748 * Added check for CUMODE_CHANGE notify type that mode change is
749 allowed by the sender. Affected file silcd/packet_receive.c.
750 Added the ID type as CUMODE_CHANGE notify type as argument
751 to the `notify' client operation. Affected files are
752 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
754 * Added function silc_client_add_server to the client library.
755 Added support for resolving also channel and server info when
756 received unknown entity in notify packet. Affected files are
757 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
759 * Added function silc_command_get_status to return the command
760 status from the command reply's argument payload. Affected files
761 are lib/silccore/silccommand.[ch].
763 * Added check for KICKED notify type that the kicking is
764 allowed by the client. Affected file silcd/packet_receive.c.
766 * Created function silc_get_input which can be used to get input
767 (echo on or off) from user on command line. Affected files are
768 lib/silcutil/silcutil.[ch].
770 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
772 * Optimized silc_server_packet_relay_to_channel function.
773 Added new function silc_channel_message_payload_encrypt which
774 can be called directly if channel message payload needs to
775 be encrypted and is already encoded (no need to call _encode
776 function). Packet relaying is now done by router without any
777 extra memory allocations. Affected files are
778 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
781 * Fixed the INVITE notify handling. It took wrong arguments
782 as invite list and invite delete. Affected file is
783 silcd/packet_receive.c.
785 * Added check for TOPIC_SET notify type that the topic change is
786 allowed by the client. Affected file silcd/packet_receive.c.
788 * Added check for INVITE notify type that inviting is allowed by
789 the client. Affected file silcd/packet_receive.c.
791 * Changed the silc_server_client_on_channel to return the
792 SilcChannelClientEntry as well. Moved the function
793 silc_server_check_cmode_rights to server_util.[ch].
794 Affected files are silcd/server_util.[ch], silcd/command.c.
796 * Added function silc_server_check_umode_rights to check whether
797 changing client's user mode is allowed. Added check for
798 UMODE_CHANGE notify type that the umode change is allowed
799 by the client. Affected files are silcd/server_util.[ch],
800 silcd/packet_receive.c and silcd/command.c.
802 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
804 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
805 ID length. It ignored that ID can be IPv6 based as well.
806 Affected file lib/silccore/silcpacket.h.
808 * Fixed the silc_id_id2str and silc_id_str2id to take the
809 IPv6 address offset's into consideration. Affecte file is
810 lib/silccore/silcid.c.
812 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
814 * Fixed the internal Unix scheduler functions to check for
815 NULL context they may receive. The affected file is
816 lib/silcutil/unix/silcunixschedule.c.
818 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
820 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
821 can specify different directory with --home command line
822 parameter. Affected files irssi/src/silc/core/client_ops.c,
825 * SILC-specific commands aren't now executed if the active server
826 isn't of SILC-type, so there won't be problems with having
827 IRC and SILC protocol support in same client. Affected files
828 irssi/src/silc/core/silc-channels.c, silc-servers.c,
831 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
833 * Improved the signal support in SILC Schedule. Added new
834 function silc_schedule_signal_call which is used by application
835 to mark a signal to be called. It is now safe to perform
836 any kind of tasks in signal callbacks since it is guaranteed
837 that the application specified signal callback is called
838 after the signal is over. Affected files are
839 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
841 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
843 * Added `name' field to SilcChannelPrivateKey to represent
844 application given name for the key. Moved also the context from
845 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
846 Added the `name' argument also to the function
847 silc_client_add_channel_private_key.
849 Added function silc_client_current_channel_private_key to set the
850 current channel private key in use.
852 Added "change" command to KEY command which can be used to change
853 the current channel private key. Bound the command also to
856 Also affected files lib/silcclient/client_channel.c,
857 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
859 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
861 * Added silc_rng_get_byte_fast function in to the
862 lib/silccrypt/silcrng.[ch].
864 * Changed the interface of silc_packet_assemble and the
865 silc_packet_send_prepare. If silc_packet_assmble is now
866 called the application does not call silc_packet_send_prepare
867 because the library will call it automatically. These
868 interfaces now also return a reference to the outgoing buffer
869 which includes the assembled packet, which the application can
870 use to encrypt the packet.
872 Affected files are lib/silccore/silcpacket.[ch],
873 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
874 silcd/packet_send.c, server_backup.c and packet_receive.c.
876 * Fixed a packet sending bug on very high load, where outgoing
877 packet queue wasn't handled correctly and packets got corrupted.
878 Affected files are lib/silcutil/*/silc*sockconn.c,
879 lib/silcclient/client.c and silcd/server.c.
881 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
883 * Added macro SILC_PACKET_DATALEN which can be used during
884 packet assembling to check whether the data to be added to
885 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
886 len is truncated until it fits it.
888 Added checks for maximum length of channel message payload and
889 private message payload also.
891 Added checks for maximum packet length in server and in
894 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
895 lib/silcclient/client.c, lib/silccore/silcchannel.c and
896 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
897 lib/silcclient/client_prvmsg.c.
899 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
901 * Added silc_server_packet_queue_purge call to the
902 silc_server_disconnect_remote to assure that all data in the
903 queue before disconnecting is sent to the network. Affected
906 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
908 * Added the deleting of server's own ID cache entry to the
909 silc_server_free function. Free also everything else that
910 has been allocated in silc_server_init. The affected file
913 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
915 * Added functions silc_parse_version_string, silc_version_to_num,
916 and silc_ske_parse_version to parse SILC protocol style version
917 strings. Affected files lib/silcutil/silcutil.[ch] and
918 lib/silcske/silcske.[ch].
920 * Added new configuration params: version_protocol, version_software
921 and version_software_vendor to specify what version the remote
922 host must at least be to be able to connect to server. The vendor
923 string can be regex matched too. Added new function
924 silc_server_connection_allowed to check maximum number of allowed
925 connections, and allowed versions for incoming connections.
926 Affected files are silcd/server.c, server_util.[ch] and
929 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
931 * Added preliminary support for signals in scheduler. The
932 signals we care about are now blocked always when the scheduler
933 is locked. This way we can synchronise the use of signal with
934 scheduler. It is guaranteed that when signal occurs the scheduler
935 is not locked, and thus new tasks can be safely added to the
938 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
939 to silc_schedule_internal_init and silc_schedule_internal_uninit.
940 Added new platform specific routines
941 silc_schedule_internal_signals_[un]block and
942 silc_schedule_internal_signal_[un]register.
944 Added new functions to SILC Schedule API:
945 silc_schedule_signal_[un]register. Each signal that application
946 is going to use should be registered to the scheduler.
948 Affected files are lib/silcutil/silcschedule.[ch],
949 lib/silcutil/*/silc*schedule.c.
951 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
953 * Check for unauthenticated client and server in the
954 silc_server_new_client and silc_server_new_server functions.
955 Affected file silcd/packet_receive.c.
957 * Added function silc_string_is_ascii to check whether given
958 string is 7-bit ASCII string. Affected files are
959 lib/silcutil/silcutil.[ch].
961 * Added function silc_id_is_valid_server_id into the
962 silcd/serverid.c and added checking for valid Server ID's in
963 silc_server_new_server. The Server ID must always be based
964 on the server's public IP address.
966 * Added logging of DISCONNECT packet message in the server.
967 Affected file silcd/server.c.
969 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
971 * Changed all library interfaces that use Global RNG to also
972 accept SilcRng as argument. Affected files are
973 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
974 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
975 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
976 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
979 * Added function silc_pkcs_generate_key to the
980 lib/silccrypt/silcpkcs.[ch] for applications so that they
981 don't need to do pkcs->pkcs->init calls anymore.
983 * Remove SilcSocketConnection from the SFTP API since it really
984 wasn't needed there. The application has the information
985 saved in its contexts anyway and the SFTP layer doesn't need
986 know about it. Affected files lib/silcsft/silcsftp.h and
987 lib/silcsftp/sftp_[server/client].c.
989 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
990 The SilcSimContext is not SilcSim.
992 * Fixed possible buffer overflows in silc_id_render in the
993 lib/silcutil/silcutil.c.
995 * On EPOC the global crypto module lists are not used at all
996 in the crypto library. Added support for using the constant
997 algorithm list on EPOC. Affected files are
998 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
1001 * Fixed the handling of third parameter of KICKED notify, since
1002 it was mistakenly updated to SILC Protocol 1.0 even though it
1003 is to be included in 1.1. Since it is not in 1.0 it is not
1004 mandatory, and this fix now handles it only if it is provided,
1005 and it is not error if it is not provided. Affected file
1006 lib/silcclient/client_notify.c.
1008 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1010 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
1011 client. Affected file irssi/src/silc/core/client_ops.c.
1013 * Merged with Irssi 0.8.4 from irssi.org CVS.
1015 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1017 * Check for valid socket connection in client entries before
1018 sending any messages. Fixes a crash, but doesn't fix some
1019 other underlaying bug that is lurking there. Affected
1020 file silcd/packet_send.c.
1022 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
1024 * $usermode, $cumode and $cumode_space expandos shouldn't do
1025 anything with non-SILC server records. Affected file

1045 file lib/silcutil/silcutil.[ch].
1047 * Added support for specifying multiple public keys for Client
1048 connection section in server configuration file. This makes it
1049 possible to accept multiple public keys from same host, or to
1050 make a section that accepts any incoming host, and have the
1051 accepted public keys listed in the section.
1053 Added functions silc_sever_[find/get]_public_key, added the
1054 support for this actually to all connection sections but only

1166 old name went against naming convention. Applications now
1167 include "silcclient.h" instead of "clientlibincludes.h".
1168 Removed includes/clientlibincludes.h, it is redundant now.
1170 * Renamed includes/version.h to silcversion.h.
1172 * Added really preliminary support for OS/2 into the util
1173 library. Only thread & mutex API is implemented, others

1230 the SKE interface a bit.
1232 * Fixed padding problem in PKCS#1. The padding was not actually
1233 random since the random number generator was used incorrectly.
1234 This security bug affects only when encrypting with PKCS#1, and
1235 it is not currently used at all in SILC. SILC only use signing
1236 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.

1321 the connection configuration object from the SilcServerConnection
1322 object instead of finding it during the connecting phase.
1323 Added the configuration object to SilcServerConnection struct.
1324 Affected files silcd/server_internal.h, server.c.
1326 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1328 * Add the client on channel after it was resolved at the
1329 channel message receiving, and it was not already on the
1330 channel. Affected file lib/silcclient/client_channel.c.
1332 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1352 public key is set. If not set, public key is preferred.
1353 This has effect only when being initiator (responder will try
1356 Added support for authentication with passphrase and public key
1357 at the same time. The passphrase is tried first always since
1358 it is faster to check.
1360 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
1362 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

1408 * Fixed the file transfer's key agreement payload to include
1409 zero port also if the hostname is NULL because it could not
1412 Call file transfer monitor callback now also if error occurs
1413 during key agreement protocol.
1415 Changed the silc_client_file_send interface to return the
1416 SilcClientFileError instead of session id. The session ID
1417 is returned into pointer provided as argument.

1436 * Fixed the channel message payload decryption in the function
1437 silc_channel_message_payload_decrypt to not modify the original
1438 buffer before it is verified that the message decrypted
1439 correctly. Otherwise, next time it is called with correct
1440 channel key it won't encrypt since the payload is corrupted.
1441 Affected file lib/silccore/silcchannel.c.
1443 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1456 the table with foreach callback. The current entry may
1457 become invalid in the callback but it was referenced after
1458 the callback returned.
1460 Do not allow auto rehashing of hash table during the
1461 silc_hash_table_foreach operation, for same reasons as it is
1462 not allowed for SilcHashTableList. Affected files are
1463 lib/silcutil/silchashtable.[ch].
1465 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>

1489 * Fixed a bug in hash table tarversing. While the hash table
1490 is traversed with SilcHashTableList the table must not be
1491 rehashed. It is now guaranteed that auto rehashable tables
1492 are not rehashed while tarversing the list. Also defined that
1493 silc_hash_table_rehash must not be called while tarversing
1494 the table. Added function silc_hash_table_list_reset that must
1495 be called after the tarversing is over. The affected files are
1496 lib/silcutil/silchashtable.[ch].
1498 * Changed all hash table traversing to call the new
1499 silc_hash_table_list_reset in server and in client library.
1501 * Added function silc_client_on_channel to return the
1502 SilcChannelUser entry if the specified client entry is joined
1503 on the specified channel. This is exported to application as
1504 well. Affected files lib/silcclient/client_channel.c, silcapi.h.

1512 * Fixed the WHOWAS command's reply sending to support the
1513 lists correctly. Affected file silcd/command.c.
1515 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1517 * When sending JOIN command to router for processing the
1518 sender's old command identifier was not saved back to the
1519 sender's command context, fixed now. The affected file is
1522 * Create the key in JOIN command of the router did not return
1523 the channel key, added check for this. Affected file is
1526 * Fixed a channel ID update bug in JOIN command reply. Do
1527 not directly upgrade the ID but call the function
1528 silc_idlist_replace_channel_id if the ID was changed.
1529 Affected file silcd/command_reply.c.
1531 * Fixed memory leaks from command calling if it would fail.
1532 Affected file silcd/command.c.

1547 with server connections. Later this will be configurable
1548 in config file after new config file is done. Affected file
1551 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1553 * Fixed a crash in server related to channel announcements.
1554 Affected file silcd/server.c.
1556 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1558 * Fixed memory leaks in silc_server_create_new_channel*
1559 functions. Affected file silcd/server.c.
1561 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
1562 which ID was changed. This way the router will send the
1563 user list for the channel again, and server won't be in
1564 desync in some rare circumstances. Affected file is
1565 silcd/packet_receive.c.
1567 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1569 * Check for NULL socket pointer in the function
1570 silc_server_packet_send_to_channel_real. Affected file
1571 silcd/packet_send.c.
1573 * Fixed the BAN notify handling to correctly remove ban
1574 list. Affected file silcd/packet_receive.c.
1576 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1578 * Fixed some header addition to Toolkit distribution in
1579 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
1581 * Added lib/silcclient/client_ops_example.h as an template
1582 file for application programmers to quickly start using
1583 the SilcClientOperation functions in their application.
1584 Updated the lib/silcclient/README as well to tell about this
1585 nice file made available.
1587 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1589 * Call silc_server_remove_from_channels when removing client
1590 entry when NO_SUCH_CLIENT_ID was received. Affected file
1591 is silcd/command_reply.c.
1593 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1595 * Added server & router operator statistics updating. Affected
1596 file silcd/packet_receive.c and silcd/command.c.
1598 * Fixed the SERVER_SIGNOFF notify handling on normal server
1599 not to save the history information for clients. Same was
1600 fixed earlier in remove_clients_by_server function, but not
1601 here. Affected file silcd/packet_receive.c.
1603 * Raised the default connection-retry count from 4 to 7 in
1604 server. Affected file silcd/server.h.
1606 * Cancel any possible reconnect timeouts when we start the
1607 key exchange. Affected file silcd/server.c.
1609 * Do not reconnect on connection failure when SCONNECT was
1610 given. Affected files silcd/server.[ch].
1612 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1614 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
1616 * Fixed the NICK command to always give the unformatted
1617 nickname to the one giving the NICK command. If unformatted
1618 nickname is cached already it will be formatted and the
1619 local entry will always get the unformatted nickname.
1620 Affected file lib/silcclient/idlist.c.
1622 * Fixed some double frees from client library commands.
1623 Affected file is lib/silcclient/command.c.
1625 * Fixed CUMODE command in server to assure that no one can
1626 change founder's mode than the founder itself, there was a
1627 little bug. Affected file silcd/command.c.
1629 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1631 * Removed the SilcClientCommandDestructor from the client
1632 libary, it is not needed anymore. Affected files are
1633 lib/silcclient/silcapi.h, command[_reply].[ch],
1634 client_notify, idlist.c.
1636 * Fixed GETKEY command to first resolve client, and then
1637 resolve the server only if the client was not found, instead
1638 of resolving both at the same time. Affected file is
1639 lib/silcclient/command.c.
1641 * Added silc_client_start_key_exchange_cb and lookup the
1642 remote hostname and IP address before starting the key
1643 exchange with server. The affected file is
1644 lib/silcclient/client.c.
1646 * The server's public key is now saved using the IP address
1647 of the server and not the servername for the filename.
1648 The hostname public key filename is checked as an fall back
1649 method if the IP address based filename is not found.
1651 Fixed the GETKEY command to save the fetched server key
1652 in correct filename.
1654 Print the remote server's hostname now when new key is
1655 received during connection process. Affected file is
1656 irssi/src/silc/core/client_ops.c.
1658 * Return always our own public key to the client if it asks
1659 for it with GETKEY command. Affected file silcd/command.c.
1661 * Removed the use_auto_addr variable from default config
1662 file since it was in wrong section. Affected file is
1665 * Fixed TOPIC_CHANGE notification to not route it when it
1666 was sent using silc_server_send_notify_to_channel function.
1667 Affected file silcd/command.c.
1669 * Fixed silc_server_send_notify_kicked to send the kicker's
1670 Client ID also, it was missing. Affected files are
1671 silcd/command.c, silcd/packet_send.[ch].
1673 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1675 * Do not save client history information in SERVER_SIGNOFF.
1676 Fixes the bug in normal server that it does not detect
1677 the client becoming valid after the server becomes back
1678 online. Affected file silcd/server_util.c.
1680 * Added `sock_error' field into the SilcSocketConnection
1681 context. When error occurs during socket operation (read
1682 or write) the error is saved. Added also new function
1683 silc_socket_get_error to return human readable socket error
1684 message. Affected files are lib/silcutil/silcsockconn.[ch],
1685 lib/silcutil/unix/silcunixsockconn.c, and
1686 lib/silcutil/win32/silcwin32sockconn.c.
1688 * The server now prints the socket error message in the
1689 signoff for client. Affected file silcd/server.c.
1691 * Fixed the `created' channel information sending from router
1692 to server in JOIN command. Checks now whether the channel
1693 really was created or not and set it according that.
1695 Fixed the JOIN command to use the client entry's current
1696 ID during the joining procedure instead of the one it sent
1697 in the command (it is checked though), since it can change
1698 between the packet processing and command processing, and
1699 would just case unnecessary pain in the client end. Affected
1700 file silcd/command.c.
1702 * Fixed a channel key payload sending to use correct channel
1703 ID when the server was forced to change the channel's ID by
1704 router. Router sent the key payload with the old Channel ID.
1705 Affected file silcd/packet_receive.c.
1707 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1709 * Call silc_server_save_channel_key only if the key payload
1710 was provided in the JOIN command's command reply. Affected
1711 file silcd/command_reply.c.
1713 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1715 * Fixed silc_mp_sizeinbase to return the value correctly with
1716 MPI. Affected file lib/silcmath/mp_mpi.c.
1718 * Fixed the stop_server signal to correctly stop the scheduler
1719 and gracefully stop the server when SIGTERM or SIGINT signals
1720 are received. Affected file silcd/silcd.c.
1722 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1724 * Simple handling of TERM and HUP signals. Also added some log
1725 flushing call around. Affected file is
1728 * Fixed small bugs in silclog.c. Now buffering output will take
1729 effect after 10 seconds since startup: This will ensure that
1730 no important startup messages are lost. Also output redirection
1731 will preserve original format ([Date] [Type] message).
1732 Affected file is lib/silcutil/silclog.c.
1734 * Added two options to the config file, in the logging section:
1735 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1736 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1738 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1740 * Do not print the warning about log files not being initialized
1741 more than once to avoid excess logging. Affected file is
1742 lib/silcutil/silclog.c.
1744 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1745 the SIM copying in make install in Makefile.am.pre.
1747 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1749 * Rewritten silclog APIs. Globally interesting changes follows:
1750 silc_log_set_files() changed to silc_log_set_file().
1751 silc_log_set_callbacks() changed to silc_log_set_callback().
1752 ROBOdoc documented silclog header file.
1753 SilcLogCb now returns bool to wether inihibit the default
1754 handler or not (to keep the old behaviour return always TRUE).
1755 The new APIs should also fix the problem of the
1756 silcd_error.log file that was written in the current directory.
1759 Log files streams will remain opened after silc_log_set_file()
1760 call, means less CPU usage notably on high traffic servers.
1761 File streams are now full buffered, and flushed to the disk
1762 every 5 minutes, lesses HD activity and CPU usage.
1763 Messages can be redirected, allowing admins to configure
1764 one single logfile for all server messages.
1765 the silc_log_quick global variable to activate fast-logging.
1766 Affected files lib/silcutil/silclog.[ch]
1768 * Changed some code to conform new silclog APIs. Affected
1769 files are doc/example_silcd.conf.in, silcd/server.c
1770 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1773 * Fixed a memory leak that could occur in some situations.
1774 Affected file silcd/serverconfig.c.
1776 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1778 * Added the silc_client_del_client to remove the client from
1779 all channels as well. Affected file lib/silcclient/idlist.c.
1781 * Fixed the client library to correctly remove the client
1782 from all channels when the client entry is being destroyed.
1783 Affected file lib/silcclient/client_notify.c, command.c.
1785 * Added auto-nicking support to the client library. If the
1786 applicatio now sets client->nickname it will be sent to the
1787 server after connecting by the library. This way for example
1788 SILCNICK (or IRCNICK) environment variables will have effect
1789 and always change the nickname automatically to whatever
1790 it is wanted. Affected file lib/silcclient/client.[ch].
1792 * Renamed silc_server_command_bad_chars to the
1793 silc_server_name_bad_chars and moved it to the
1794 silcd/server_util.[ch]. Added also new function
1795 silc_server_name_modify_bad to return nickname that
1796 includes bad characters as new nickname without those
1797 bad characters. This check and modify is now used in
1798 silc_server_new_client when the username is initially set
1799 as nickname, so it must be checked to be valid nickname.
1800 Affected file silcd/packet_receive.c.
1802 * The nickname length is now taken from the packet for real
1803 and not trusted to strlen() since it clearly can return
1804 wrong length for nickname including bad characters. This
1805 also applies to channel names. Affected file silcd/command.c.
1807 * Removed the lib/silcsilm/modules directory. Modules are now
1808 compiled into the lib/silcsim. Fixed the copying of the
1809 modules to follow symbolic links in Makefile.am.pre.
1811 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1813 * Fixed silc_string_regexify list creation. Fixes bugs with
1814 BAN and INVITE commands in server. The affected file is
1815 lib/silcutil/unix/silcunixutil.c.
1817 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1819 * Removed the command destructor entirely from the server's
1820 command and command reply routines. It is not needed, and
1821 its usage was buggy and caused crashes. Affected files are
1822 silcd/command[_reply].[ch].
1824 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1826 * Cancel protocol and NULL sock->protocol if timeout
1827 occurred during protocol. Affected file silcd/server.c.
1829 * Cancel protocol timeouts always before calling the final
1830 callback, to assure that after final callback is called
1831 no other state will be called for the protocol anymore.
1832 Affected file silcd/protocol.c.
1834 * Print error log if incoming connection configuration could
1835 not be found. Affected file silcd/server.c.
1837 * Fixed JOIN command to correctly save the founder mode
1838 to the client on normal SILC server, when the channel
1839 was created by the router. Affected file silcd/command.c.
1841 * Fixed LIST command (hopefully) to send correct reply
1842 packets. Affected file silcd/command.c.
1844 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1846 * The silc_packet_receive_process now returns FALSE if the
1847 read data was invalid packet, and TRUE if it was ok.
1849 The server now checks that if unauthenticated connection
1850 sends data and its processing fails the server will close
1851 the connection since it could be a malicious flooder.
1853 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1855 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1857 * Make sure the warning about error opening a log file is
1858 printed only once and not everytime it fails (produces
1859 too much useless log). Affected file lib/silcutil/silclog.c.
1861 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1863 * Made the silc_server_daemonise() function more readable.
1864 Affected file silcd/server.c.
1866 * Pid file is now optional, the user may comment it out from
1867 the config file. Removed define SILC_SERVER_PID_FILE, we
1868 don't need a default any longer. Affected file
1869 configure.in.pre, lib/Makefile.am.pre.
1871 * Make some use of the pid file. The server now dies at startup
1872 if it detects a valid pid file on his path. The server would
1873 die anyway in this circumstance, because of the bind() failure.
1874 Affected file silcd/silcd.c.
1876 * No longer compiling lib/dotconf.
1878 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1880 * Fixed JOIN command parsing not to crash. Affected file
1881 lib/silcclient/command.c.
1883 * Fied the NICK_CHANGE notify to add the new client entry
1884 even it is resolved. This removes an <[unknown]> nick
1885 thingy bug in the client. Affected file is
1886 lib/silcclient/client_notify.c.
1888 * Do not try to allocate 0 bytes (efence does not like it)
1889 in lib/silccore/silccomand.c when encoding payload.
1891 * Do not take IRCNICK as nickname in Irssi SILC client since
1892 it is not possible to set nickname before hand connecting
1893 the server (TODO has an entry about adding auto-nicking
1896 * Changed the silc_server_command_pending to check whether
1897 there already exists an pending entry with the specified
1898 command, command identifier and pending callback. This is
1899 to fix IDENTIFY and WHOIS related crashes that may register
1900 multiple pending commands with same identifier. Affected
1901 file silcd/command.c.
1903 * Fixed the server to reconnect to the router even if it
1904 was already reconnecting and EOF was received. This to
1905 fix a possibility that the server wouldn't ever try to
1906 auto-reconnect to the router. Affected file silcd/server.c.
1908 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1910 * Fixed the server's password authentication to use the
1911 length of the locally saved password, and not the one
1912 sent in the packet. Affected file silcd/protocol.c.
1914 * Fixed same password authentication problem in the
1915 Authentication Payload handling routines in
1916 lib/silccore/silcauth.c.
1918 * Yet another password authentication problem fixed with
1919 channel password handling in silcd/command.c.
1921 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1923 * If first character of string in silc_parse_userfqdn is '@'
1924 then do not parse it. Affected file is
1925 lib/silcutil/silcutil.c.
1927 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1929 * Fixed minor bug in IDENTIFY command reply sending, which
1930 caused various weird problems during JOIN when it was
1931 resolving names for users. Affected file silcd/command.c.
1933 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1935 * Fixed the IDENTIFY command reply sending to chech better valid
1936 clients. It was possible to send incomplete list of replies.
1937 Affected file silcd/command.c.
1939 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1941 * Added silc_client_command[s]_[un]register functions now to
1942 dynamically register the commands in client library. Removed
1943 the static table of commands. This allows the client library
1944 to call commands without causing the application to know about
1945 what commands library has called.
1947 Removed the INFO command reply kludge to detect when the command
1948 was called by library. Now library use its own command reply
1949 function for INFO command.
1951 Added function silc_client_command_call to call a command.
1952 Application can use it to call command, not access the structure
1955 Now all commands that are sent by the client library (not
1956 explicitly sent by application) use own command reply functions.
1958 Affected files around lib/silcclient/ and in
1959 irssi/src/silc/core/.
1961 * Fixed the WHOIS command reply sending to chech better valid
1962 clients. It was possible to send incomplete list of replies.
1964 Fixed the WHOIS and IDENTIFY to send the request to router
1965 if normal server did not do it and did not find any results.
1967 Affected file silcd/command.c.
1969 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1971 * Moved the internal data from SilcClient context into its
1972 own file, not accesible to application. Affected files
1973 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1974 and other files in client library.
1976 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1978 * Added doc/examples installation target in Makefile.am.pre.
1981 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1983 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1984 commands the found client entry will be removed from the
1985 cache, after notifying application about the error. Affected
1986 file lib/silcclient/command_reply.c.
1988 * Changed the /MSG to check for exact nickname user gave, and
1989 not let `nick' match `nick@host' if it is only one found. Now,
1990 user must type the exact nickname (like nick@host2) even if
1991 there are no more than one same nicks found. This is to avoid
1992 a possibility of sending nickname to wrong nickname since
1993 `nick' could match `nick@host'. Affected file is
1994 irssi/src/core/silc-servers.c.
1996 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1998 * Do not print "you are now server operator" or similar when
1999 giving /away command. Affected files are
2000 irssi/src/silc/core/client_ops.c, silc-servers.h.
2002 * Made the silc_server_command_pending_error_check to send
2003 the same command reply payload it received back to the
2004 original sender of the command. This way all arguments
2005 that was received by the server will be received by the
2006 client too. Affected file silcd/command.c.
2008 * Added the silc_idcache_add to return the created cache entry
2009 to a pointer. Affected file lib/silccore/silcidcache.[ch].
2011 * Add global clients to expire if they are not on any channel.
2012 This is because normal server will never know if they signoff
2013 if they are not on any channel. The cache expiry will take
2014 case of these entries. This is done by normal servers only.
2015 The affected files are silcd/command_reply.c,
2016 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
2018 * If server receives invalid ID notification for WHOIS or
2019 IDENTIFY and the ID exists in the lists, it is removed.
2020 Affected file silcd/command_reply.c.
2022 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
2023 in client then client entry that it matches is searched and
2024 the nickname is printed on the screen for user. Affected
2025 file irssi/src/silc/core/client_ops.c.
2027 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2029 * Use cache entry expire time in the LIST command reply to
2030 purge old entries from the cache after the LIST command
2031 reply has been received. This way we don't have non-existent
2032 entries in the cache for too long. Affected file is
2033 silcd/command_reply.c.
2035 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2037 * If we are normal server, and we've not resolved client info
2038 in WHOIS or IDENTIFY from router, and it is global client,
2039 we'll check whether it is on some channel. If it is not
2040 then we cannot be sure about its validity and will resolve it
2041 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
2042 file silcd/command.c.
2044 * Search channel by name (if possible) rather than by ID
2045 in IDENTIFY command's command reply. Affected file is
2046 silcd/command_reply.c.
2048 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2050 * Distribute to the channel passphrase in CMODE_CHANGE notify.
2051 Updated specs and implemented it. Affected file silcd/command.c,
2052 silcd/packet_send.c and silcd/packet_receive.c.
2054 * Implemented the <founder auth> payload handling in the JOIN
2055 command. If provided all conditions for channel joining
2056 except requirement to provide correct passphrase can be
2057 overrided by the channel founder. Updated the protocol specs.
2058 Affected file silcd/command.c.
2060 Added support for founder auth in JOIN command in client
2061 library. Fixed the parsing of the JOIN command now to support
2062 all options as they should be. The affected file is
2063 lib/silcclient/command.c.
2065 * Optimized the WHOIS and IDENTIFY commands to send the request
2066 to router only if it includes nicknames or other names. If
2067 they include only IDs then check the local cache first before
2068 routing. Affected file is silcd/command.c.
2070 * Added channels topic announcements. Affected file is
2071 silcd/packet_receive.c and silcd/server.c.
2073 * Fixed the silc_server_send_notify_topic_set to really destine
2074 the packet to channel. Affected file silcd/packet_send.c.
2076 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
2077 library. Affected file lib/silcclient/client_notify.c.

2099 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2101 * Update the client entry context in the ID cache after
2102 nick change. Affected file lib/silcclient/command.c.
2103 Fixes the CUMODE command when regaining founder privileges,
2104 and a little WHOIS problem.
2106 * Fixed silc_net_gethostbyname to correctly call the
2107 inet_ntop. Affected file lib/silcutil/silcnet.c.
2109 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2111 * Added IPv6 support checking to the configure.in.pre, added
2112 also --enable-ipv6 option to override the check. Affected
2113 file configure.in.pre.
2115 * The silc_thread_create now calls the start function
2116 directly if threads support is not compiled in. Removes
2117 ugly #ifdef's from generic code. Affected files are
2118 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
2120 * Added silc_net_gethostby[name/addr]_async to asynchronously

2139 * Fixed LIST command reply sending in server. Affected file
2142 * Server now sends the kicker's client ID in the KICK notify
2143 to the kicked client. Affected file silcd/command.c.
2145 * The client library now parses the kickers client ID and
2146 UI displays it. Affected files lib/silcclient/client_notify.c
2147 and irssi/src/silc/core/silc-channels.c, module-formats.c.
2149 * Made all payload parsing function prototypes consistent.
2150 They all take now const unsigned char * and uint32 pair as
2151 the payload data instead of SilcBuffer. Changes all around
2152 the source tree. Other unsigned char* -> const unsigned char*
2153 changes around the tree as well.
2155 * Optimized SFTP client and server packet sending not to
2156 allocate new buffer for each packet but to recycle the
2157 first allocated buffer. Affected files are
2158 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
2160 * Optimized the SFTP client to use SilcList instead of
2161 SilcDList for requests, because it is faster. Affected file
2162 is lib/silcsftp/sftp_client.c.
2164 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
2165 into lib/silccore/silcid.[ch].
2167 Renamed silcpayload.[ch] into silcargument.[ch].
2169 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2171 * If client entry is deleted with active key agreement
2172 session, abort the session.
2174 The silc_client_abort_key_agreement now calls the completion
2175 callback with new SILC_KEY_AGREEMENT_ABORTED status.
2177 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
2180 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2182 * Don't use __restrict in older GCC's. Affected file is
2183 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
2185 * silc_net_localhost now attempts to reverse lookup the
2186 IP/hostname. Affected file lib/silcutil/silcnet.c.
2188 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
2189 command. It can be used to gain founder privileges at
2190 the same time when joining the channel.
2192 Defined that the SILC_NOTIFY_TYPE_KICKED send the
2193 kicker's client ID as well. Updated protocol specs.
2195 Defined that the server must send SILC_COMMAND_IDENTIFY
2196 command reply with error status to client who sent
2197 private message with invalid client ID.
2199 Updated the protocol specification.
2201 * Added silc_server_send_command_reply to send any
2202 command reply. Affected file silcd/packet_send.[ch].
2204 * Added silc_id_payload_encode_data to encode ID payload
2205 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
2207 * The server now send IDENTIFY command reply with error
2208 status if client ID in private message is invalid. Affected
2209 file silcd/packet_receive.c.
2211 * Save the server key file with server's IP address in
2212 the filename instead of hostname. The affected file is
2213 irssi/src/silc/core/client_ops.c.
2215 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2217 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
2220 * Added libtool support for compiling shared objects in
2221 lib/silcsim. Affected file configure.in.pre and
2222 lib/silcsim/Makefile.am. Original patch by cras.
2224 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2226 * Pid file configuration, and server's config file fixes
2227 patch by toma. Updated CREDITS file.
2229 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2231 * Fixed silc_client_channel_message to not try to decrypt
2232 the message twice if it resolved the destination client
2233 information. This could cause of dropping one channel
2234 message. Affected file lib/silcclient/client_channel.c.
2236 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2238 * Added silc_client_run_one into lib/silcclient/silcapi.h and
2239 lib/silcclient/client.c. This function is used when the SILC
2240 Client is run under some other scheduler, or event loop or
2241 main loop. On GUI applications, for example this may be
2242 desired to used to run the client under the GUI application's
2243 main loop. Typically the GUI application would register an
2244 idle task that calls this function multiple times in a second
2245 to quickly process the SILC specific data.
2247 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2249 * Fixed silc_server_drop() for dropping the supplementary
2250 groups as well, this could cause a security hole on some
2253 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2255 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
2258 * Write PID file after dropping privileges. Added -F option
2259 to run server on foreground. A patch by debolaz.
2260 Affected files silcd/server.c, silcd/silcd.c.
2262 * Fixed MOTD to return the MOTD file server name. Affected
2263 file silcd/command.c.
2265 * Added INFO command reply handling to the Irssi SILC Client.
2266 Affected file irssi/src/silc/core/client_ops.c.
2268 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2270 * Fixed the silc_idcache_list_* routines to really support
2271 the dynamic list. Fixes a crash. Affected file is
2272 lib/silccore/silcidcache.c.
2274 * Fixed the LIST command reply to really call LIST command's
2275 pending callbacks. Affected file silcd/command_reply.c.
2277 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2279 * Update conn->local_entry->nickname after giving NICK
2280 command. Affected file lib/silcclient/command.c.
2282 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
2284 * Added the [pid] option to the silcd configuration file
2286 Affected files: serverconfig.[ch] and silcd.c
2288 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2290 * Save fingerprint in WHOIS command reply in server.
2291 Affected file silcd/command_reply.c.
2293 * Fixed NICK commands pending callback registration.
2294 Affected file lib/silcclient/command.c.
2296 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2298 * Use ++server->cmd_ident when sending commands in server,
2299 instead of random number. Affected file silcd/command.c.
2301 * Fixed GETKEY command reply to call actually GETKEY pending
2302 command callbacks. Affected file silcd/command_reply.c.
2304 * A bit stricter check for nicknames. Check for same nickname
2305 in NICK command also. Affected file silcd/command.c.
2307 * Do not call INFO command everytime client ID changes, only
2308 during first connecting. Affected file lib/silcclient/client.c.
2310 * Set the new nickname only after successful command reply for
2311 NICK command is returned by server. Affected file
2312 lib/silcclient/command.c.
2314 * Remove nicknames from nicklist during server_signoff notify.
2315 Should fix /NAMES bit more. The affected file is
2316 irssi/src/silc/core/silc-channels.c.
2318 * Added `fingerprint' field to the SilcIDListData in the
2319 silcd/idlist.h to hold the fingerprint of the client's
2322 Send the fingerprint of the client's public key in WHOIS
2325 Affected files silcd/command.c, and silcd/idlist.[ch].
2327 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
2328 create fingerprint from given data.
2330 * Show the fingerprint of the client's public key in WHOIS.
2331 Affected files irssi/src/module-formats.[ch] and
2332 irssi/src/silc/core/client_ops.c.
2334 * Format the multiple same nicknames also during JOIN and
2335 NICK_CHANGE notifys. Affected file is
2336 lib/silcclient/client_notify.c.
2338 * Do not print error on screen for invalid private message
2339 payload since it can come if someone is sending private
2340 messages with wrong key. Affected file
2341 lib/silccore/silcprivate.c.
2343 * Fixed multiple concurrent /PING crash. Affected file
2344 lib/silcclient/command.c.
2346 * Changed the wrong ID encoding. All IP addresses must be
2347 in MSB first order in encoded format. They were encoded
2348 wrong and was in LSB format. Affected files are
2349 silcd/serverid.c, lib/silcutil/silcutil.c.
2351 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
2353 * Call the `connect' client operation through the scheduler
2354 in case of error. Affected file lib/silcclient/client.c.
2356 * Call the `failure' client operation even if the error
2357 occurred locally during a protocol. Affected file is
2358 lib/silcclient/protocol.c.
2360 * Added support of sending LIST command to router from normal
2361 server. This way normal server can get list of all channels
2362 in the network too. Fixed the channel list sending in the
2363 server too. Affected files are silcd/command.c, and
2364 silcd/command_reply.[ch].
2366 * Added silc_server_update_channels_by_server and
2367 silc_server_remove_channels_by_server. They are used during
2368 disconnection of primary router and in backup router protocol.
2369 Affected file silcd/server_util.[ch], silcd/server.c and
2370 silcd/server_backup.c.
2372 * Fixed channel adding to global list in IDENTIFY command
2373 reply in server. Affected file silcd/command_reply.c.
2375 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2377 * If the incoming packet type is REKEY or REKEY_DONE process
2378 that packet always synchronously. Fixes yet another MAC
2379 failed error on slow (dialup) connections. Affected file
2380 lib/silcclient/client.c and silcd/server.c.
2382 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2384 * Call check_version SKE callback for initiator too. Affected
2385 file lib/silcske/silcske.c.
2387 * Implemented fix for security hole found in the SKE that was
2388 fixed in the specification few days back; the initiator's
2389 public key is now added to the HASH value computation.
2390 Added backwards support for the old way of doing it too, for
2391 old clients and old servers. Affected file is
2392 lib/silcske/silcske.c.
2394 * Enabled mutual authentication by default in SKE. If initiator
2395 is not providing mutual authentication the responder will
2396 force it. This will provide the proof of posession of the
2397 private key for responder. The affected files are
2398 lib/silcclient/protocol.c and silcd/protocol.c.
2400 * Do not cache anymore the server's public key during SKE.
2401 We do mutual authentication so the proof of posession of
2402 private key is done, and if the server is authenticated in
2403 conn auth protocol with public key we must have the public
2404 key already. Affected file silcd/protocol.c.
2406 * Added new global debug variable: silc_debug_hexdump. If
2407 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
2408 file lib/silcutil/silclog.[ch].
2410 * Fixed compilation warning due to char * -> const char *.
2411 Affected files lib/silcutil/silcnet.h, and
2412 lib/silccore/silcauth.[ch].
2414 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2416 * Fixed CMODE command when new channel key was created. If
2417 the creation failed the old key was removed. Next time giving
2418 same command would crash the server since the old key was
2419 freed already. Affected file silcd/command.c.
2421 * Fixed the silc_server_announce_get_channels to not crash
2422 on reconnect. Affected file silcd/server.c.
2424 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2426 * Added silc_log_set_debug_string function to set a regex
2427 string to match for debug output. Only the function names,
2428 or filenames matching the given debug string is actually
2429 printed. This way it is possible to filter out those debug
2430 strings that user is not interested in.
2432 Fixed a bug in silc_string_regexify.
2434 Affected files lib/silcutil/silclog.[ch], and
2435 lib/silcutil/unix/silcunixutil.c.
2437 * Changed the -d options in both server and Irssi SILC client
2438 to take the debug string as argument. Affected files
2439 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
2441 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2443 * Added silc_hash_babbleprint to create a Bubble Babble
2444 Encoded fingerprint. The encoding is developed by Antti
2445 Huima (draft-huima-babble-01.txt), and it creates human
2446 readable strings out of binary data. Affected file
2447 lib/silccrypt/silchash.[ch].
2449 * Print the babble print now in addition of fingerprint as well
2450 in Irssi SILC client. Affected files are
2451 irssi/src/fe-common/silc/module-formats.[ch],
2452 irssi/src/fe-common/silc/core/client_ops.c.
2454 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2456 * Fixed a security problem found in SKE. The initiator's
2457 public key too is now added to the HASH hash value creation
2458 which is signed by the responder to create the SIGN value.
2459 This will prevent anyone in the middle to lie to the responder
2460 about the initiator's public key. If this is done now, the
2461 man in the middle will get caught. Updated the protocol
2464 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2466 * Better installation directory handling. Configure module
2467 paths and other paths automatically to example_silc* files
2468 in doc/. A patch by toma.
2470 * Fixed compiler warning from MPI library, and from SILC RNG.
2473 * Added SILC_SERVER_PID_FILE to define the pid file for server.
2474 It can be configured with ./configure. A patch by toma.
2476 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2478 * Find correct make to use in prepare-clean. A patch by
2479 toma. Affected file prepare-clean.
2481 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
2483 * Added irssi variables use_auto_addr, auto_bind_ip,
2484 auto_bind_port and auto_public_ip.
2486 * Changed the interface for silc_client_send_key_agreement
2487 in lib/silcclient/silcapi.h
2491 irssi/src/silc/core/silc-core.c
2493 lib/silcclient/silcapi.h
2494 irssi/src/silc/core/silc-channels.c
2495 lib/silcclient/client_keyagr.c
2498 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2500 * Added silc_pkcs_public_key_compare to compare two
2501 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
2503 * Check that the client who set the founder mode on the
2504 channel is the same client that is giving the founder
2505 mode to itself. It is done by comparing the saved public
2506 key (it is saved even in the authentication is passphrase).
2507 Affected file silcd/command.c.
2509 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2511 * Do not process packet for disconnected socket connection.
2512 Affected file lib/silccore/silcpacket.c.
2514 * Process the DISCONNECT packet through scheduler in the
2515 client library. Affected file lib/silcclient/client.c.
2517 * Fixed the silc_client_packet_parse to not to increase
2518 the packet sequence number if the conn->sock and the
2519 current socket connection is not same. This can happen
2520 for example during key agreement when the conn includes
2521 multiple socket connections (listeners). Affected file
2522 lib/silcclient/client.c.
2524 * The sender of the file transfer request now provides also
2525 the pointer (listener) for the key exchange protocol. If
2526 the listener cannot be created then it sends empty key
2527 agreement and lets the receiver provide the listener.
2529 Added `local_ip' and `local_port' arguments to the
2530 silc_client_file_send. If they are provided they are used,
2531 if not then it will attempt to find local IP address, if
2532 not found or bind fails then the remote client will provide
2535 Affected files are lib/silcclient/client_ftp.c and
2536 lib/silcclient/silcapi.h.
2538 * Extended the FILE SEND command to support defining the
2539 local IP and port for key exchange listener. They are
2540 optional. Affected file irssi/src/silc/core/silc-servers.c.
2542 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2544 * Defined to WHOIS command reply the sending of fingerprint
2545 of the client's public key (if the proof of posession of the
2546 corresponding private key is verified by the server).
2547 Updated to the protocol specification.
2549 * Added support of receiving the client's public key's
2550 fingerprint in command reply in client library. Affected
2551 file is lib/silcclient/command_reply.c, and
2552 lib/silcclient/idlist.[ch].
2554 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2556 * Do not send over 128 chars long nickname to the server
2557 in NICK command. Affected file lib/silcclient/command.c.
2559 * Do not send over 256 chars long channel names to the server
2560 in JOIN command. Affected file lib/silcclient/command.c.
2562 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2564 * Assure that silc_server_close_connection cannot be called
2565 twice for same socket context. Affected file is
2568 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2570 * Send error message to application if opening file for
2571 writing during file transfer fails. Affected file is
2572 lib/silcclient/client_ftp.c.
2574 Remove all file transfer sessions for a client that we're
2575 removing from ID cache.
2577 Affected file is lib/silcclient/client_ftp.c.
2579 * Fixed silc_net_addr2bin to return correct address. Affected
2580 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2582 * Fixed file transfer session removing on signoff notify.
2583 Affected file irssi/src/silc/core/silc-servers.c.
2585 * Added the SilcClientFileError to be returned in the monitor
2586 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
2587 Affected file lib/silcclient/silcapi.h.
2589 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2591 * Fixed a crash in silc_client_ftp_free_sessions and
2592 silc_client_ftp_session_free_client. Affected file
2593 lib/silcclient/client_ftp.c.
2595 * Added `disabled' field in the SilcChannelEntry in the server
2596 to indicate if the server entry is disabled. Affected file
2597 silcd/idlist.h, silcd/command[_reply].c.
2599 * SILC server adds now /var/run/silcd.pid everytime it is
2600 started. Affected file silcd/silcd.c.
2602 * Added silc_server_packet_send_clients to send a packet to
2603 the provided table of client entries. Affected file
2604 silcd/packet_send.[ch].
2606 * Fixed a crash in client resolving in client_prvmsg.c in
2607 client library. Affected file lib/silcclient/client_prvmsg.c.
2609 * Do not actually remove the client directly from ID cache
2610 during SERVER_SIGNOFF, but invalidate it. This way we
2611 preserve the WHOWAS info for the client. Affected file
2612 silcd/server_util.c.
2614 * Fixed SERVER_SIGNOFF notify handling in the server. The
2615 server is now able to process incoming SERVER_SIGNOFF notify
2616 for a server that it doesn't even know about. It will remove
2617 the clients provided in the notify. Affected file
2618 silcd/packet_receive.c.
2620 * Check for partial packet in data queue after every packet that
2621 was found from the queue. Return and wait for more data if
2622 there is partial data in queue. Affected file is
2623 lib/silccore/silcpacket.c.
2625 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>

2634 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
2636 * Added better monitor of file transfers. It now monitors
2637 key agreement protocol during the file transfer too. Added
2638 error reporting too. Affected files
2639 irssi/src/silc/core/silc-servers.c,
2640 irssi/src/fe-common/silc/module-formats.[ch].
2642 * Wrote a help file for FILE command.
2644 * Added silc_rng_global_get_byte_fast to get not-so-secure
2645 random data as fast as possible. Random data is read from
2646 /dev/urandom if available and from the SILC RNG if not
2647 available. It is used in padding generation. Affected file
2648 lib/silccrypt/silcrng.[ch].
2650 * All packets in client library are now processed synchronously.
2651 Optimized packet processing a lot. Affected file
2652 lib/silcclient/client.c.

2655 now in server, to optimize packet processing. Affected file
2658 * Include files are installed now only in Toolkit distribution
2659 if make install is given. Affected files: all Makefile.am's.
2661 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2663 * Assure that silc_client_notify_by_server_resolve does not
2664 resolve the client information multiple times. If it cannot
2665 be found by the first it cannot be found at all. Affected
2666 file lib/silcclient/client_notify.c.
2668 * Fixed WHOWAS command reply calling. Affected file
2669 lib/silcclient/command_reply.c.
2671 * Removed all references to silc_idlist_get_client from the
2672 Irssi SILC client since that call is internal call used by
2673 the library. The Irssi SILC client will use now client
2674 retrieval functions found in silcapi.h.
2676 * Fixed a bug in resolving nickname info before sending
2677 private message. It used freed memory. Affected file
2678 irssi/src/silc/core/silc-servers.c.
2680 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2682 * Assure my_channels statistics cannot go negative in server.
2683 Affected files silcd/server.c, silcd/server_util.c.

2699 * Added silc_net_localip to return local host's IP address.
2700 Affected file lib/silcutil/silcnet.[ch].
2702 * If key exchange or rekey protocol is active for a connection
2703 parse all packets syncronously since there might be packets
2704 in packet queue that we are not able to process without first
2705 processing packets before them. Affected file silcd/server,
2706 lib/silcclient/client.c.
2708 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2709 whether library should continue processing the packet.
2710 Affected file lib/silccore/silcpacket.h.

2756 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
2757 is incomplete and is being resolved, it won't be resolved
2760 Make sure also that USERS command reply does not resolve
2761 twice information. Affected file is
2762 lib/silcclient/command_reply.c.
2764 Make sure that silc_client_get_clients_by_list does not
2765 resolve twice same information.
2767 * Check for valid client->id in the silc_server_free_client_data.
2768 Affected file silcd/server.c.
2770 * Fixed /GETKEY nick@server not to crash if the server entry
2771 is not found. Affected file lib/silcclient/command.c.
2773 * Fixed the silc_server_check_cmode_rights to check the
2774 requested modes correctly. Affected file silcd/command.c.

2779 Affected file silcd/command.c.
2781 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2783 * Call the silc_server_udpate_servers_by_server in the
2784 primary router that comes back online in the backup resuming
2785 protocol. Otherwise it routes packets wrong. Affected file
2786 silcd/server_util.[ch], silcd/server_backup.c.
2788 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2790 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2791 lib/silcutil/silcbuffmt.[ch].
2793 * Redefined the SILC packet header to include the padding
2794 length. Affected file lib/silccore/silcpacket.[ch].
2796 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2797 length for maximum padding up to 128 bytes). Affected
2798 file lib/silccore/silcpacket.h.
2800 * Removed all backwards support for old 0.5.x MAC thingies.
2801 The SILC packet header change makes it impossible to be
2802 backwards compatible.
2804 * Send the ENDING packet with timeout in the backup resuming
2805 protocol. This is to assure that all routers has connected
2806 to the primary router. Affected file silcd/server_backup.c.
2808 * Changed the RNG to take the first IV from random data. It
2809 used to take it from zero actually. Changed the RNG also
2810 to use /dev/urandom during session. /dev/random is used
2811 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2813 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2815 * Changed the SILC packet header to have the first two bytes
2816 (the packet length) encrypted. Affected files aroung the
2817 code tree, lib/silccore/silcpacket.[ch]. Removed the
2818 SilcPacketCheckDecrypt callback. It is not needed anymore
2819 since the silc_packet_receive_process will determine now
2820 whether the packet is normal or special.
2822 * Implemented the unidirectional MAC keys. Affected files
2823 lib/silcske/silcske.c, silcd/protocol.c and
2824 lib/silcclient/protocol.c.
2826 * Implemented the packet sequence number to the MAC computation.
2827 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
2828 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
2829 lib/silcclient/protocol.c.
2831 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2833 * Allow backup router to announce servers. All servers
2834 announced by backup router are added to the global list
2835 automatically. Update hte server's socket to our primary
2836 router also when backup router announces a server.
2837 Affected file silcd/packet_receive.c.
2839 * Do not update the client->router in the function
2840 silc_server_udpate_clients_by_server if the client is on
2841 global list. We might fail to find any specific server
2842 for locally connected clients and local cell clients. They
2843 should still use the `from' and not `to' as client->router.
2844 This fixes backup router resuming protocol. Affected file
2845 silcd/server_util.c.
2847 * Decrease channel statistics count only if the channel
2848 deletion worked. Affected files are silcd/server.c and
2849 silcd/server_util.c.
2851 * Added silc_server_update_servers_by_server to update origin
2852 of all server entries. Used during backup router protocol.
2853 Affected files silcd/server_util.[ch], silcd/server.c. and
2854 silcd/backup_router.c.
2856 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
2857 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
2858 silc_hmac_get_hash and silc_hmac_get_name. Affected file
2859 lib/silccrypt/silchmac.c.
2861 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2863 * Assure that router cannot reroute the same channel message
2864 to the sender. Affected file silcd/packet_receive.c.
2866 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2868 * Made better checks that the channel message is not sent
2869 to the router it came from. Affected file is
2870 silcd/packet_send.c. Fixed memory leak too.
2872 * Announce informations for incoming router connection, but
2873 only after checking if it is replaced by backup router.
2874 Affected file silcd/packet_receive.c.
2876 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2878 * Fixed the backup resuming protocol to work in multiple
2879 router environment. Affected file silcd/server_backup.c.
2881 * Route packet only to one router in the function
2882 silc_server_packet_send_to_channel. Affected file is
2883 silcd/packet_send.c.
2885 * Fixed silc_server_send_notify_dest to set the broadcast
2886 flag. Fixed the silc_server_send_notify_topic to actually
2887 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2888 Affected file silcd/packet_send.c.
2890 * Changed the SFTP Filesystem interface. Changed the
2891 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2892 the filesystem operation function. The SilcSFTPFilesystem
2893 is now a context that is allocated by all filesystem allocation
2894 functions and it already includes the operations structure
2895 and filesystem specific context. It is given as argument
2896 now to the silc_sftp_server_start. This made the interface
2897 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2898 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2900 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2902 * Changed the backup router adding and getting interfaces
2903 in the server. The router that will be replaced by the
2904 specified backup router is now sent as argument. Affected
2905 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2908 * Added silc_net_addr2bin_ne to return the binary form of
2909 the IP address in network byte order. Affected files
2910 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
2912 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2914 * Check for existing server ID in silc_server_new_server
2915 and in silc_server_connect_to_router_final and remove the
2916 old entry if it exists. Affected file silcd/packet_receive.c,
2919 * Send the channel message always to only one router, either
2920 in upstream or downstream. Affected file is
2921 silcd/packet_send.c.
2923 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2925 * Wrote the definition of the backup resuming protocol to the
2926 protocol specification.
2928 * Removed one redundant channel key generation from normal
2929 server during joining procedure. Removed one redundant
2930 channel key sending from server to router during joining
2931 procedure. Affected file silcd/command.c.
2933 * Made minor bugfixes to the backup router resuming protocol.
2934 Affected file silcd/server_backup.c, server.c.

2939 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
2942 * Implemented the backup resuming protocol that is used to
2943 resume the primary router position in the cell after the
2944 primary router comes back online. Affected files
2945 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
2946 and silcd/server_util.[ch].
2948 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2950 * Sleep two (2) seconds after sending QUIT command to server.
2951 Affected file lib/silcclient/command.c.
2953 * Assure that if outgoing data buffer is pending do not force
2954 send any data. Affected file silcd/packet_send.c.
2956 * Assure that if outgoing data buffer is pending do not force
2957 send any data. Affected file lib/silcclient/client.c.
2959 * Implemented the backup router support when the primary router
2960 goes down. The servers and routers can now use the backup
2961 router as new primary router without loosing connectivity.
2963 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2965 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
2966 in the server to indicate disabled entry. All data read
2967 from the connection will be ignored and no data is sent
2968 for entry that is disabled. Affected files are
2969 silcd/idlist.h, silcd/server.c.
2971 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2973 * Created SFTP client and server test programs in the
2974 lib/silcsftp/tests directory.
2976 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2978 * Implemented memory filesystem (virtual filesystem) for
2979 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
2982 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2984 * Implemented the SFTP (SSH File Transfer Protocol) to the
2985 lib/silcsftp. It includes SFTP client and SFTP server
2988 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2990 * Moved lib/silccore/silcprotocol.[ch] to the
2991 lib/silcutil library.
2993 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
2994 take variable argument list pointer as argument. Affected
2995 file lib/silcutil/silcbuffmt.[ch].
2997 * Added silc_buffer_set function that is used to set data
2998 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
2999 Affected file lib/silcutil/silcbuffer.h.
3001 * Changed various routines in the core library to use the new
3002 silc_buffer_set instead of allocating new buffer only for
3005 * Added 64-bit value formatting and unformatting support to the
3006 silc_buffer_[un]format routines. Affected file is
3007 lib/silcutil/silcbuffmt.[ch].
3009 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
3010 to includes/bitmove.h.
3012 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3014 * Fixed channel user mode saving in client library. Affected
3015 file lib/silcclient/command[_reply].c.
3017 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3019 * Defined the file transfer to the SILC Protocol. Added
3020 new packet type SILC_PACKET_FTP and defined File Transfer
3021 Payload. The mandatory file transfer protocol is SFTP
3022 (SSH File Transfer Protocol). Affected file in addition
3023 of the internet draft is lib/silccore/silcpacket.h.
3025 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
3026 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
3027 is used as part of backup router protocol when the primary
3028 router of the cell is back online and wishes to resume
3029 the position as primary router.
3031 * Redefined the MAC generation keys in the protocol. The
3032 same key is not used anymore in both direction. Both
3033 direction will now use different keys for sending and
3034 receiving. This fixes a potential security flaw. This
3035 change causes incompatibilities in the protocol.
3037 * Redefined also the MAC computation from the packet.
3038 An packet sequence number is now added to the MAC
3039 computation. This prevents possible replay attacks against
3040 the protocol. This change too causes incompatibilities
3043 Added `sequence' field to the SilcPacketContext to hold
3044 the current sequence number for the packet.
3046 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3048 * Added `created' field to the SilcIDListData in the file
3049 silcd/idlist.h to indicate the time when the entry was
3052 * Added `created' field to the SilcChannelEntry too. Affected
3053 file silcd/idlist.h.
3055 * Added `creation_time' aguments to all the announcement functions
3056 in the server. If it is provided then only the entries that
3057 was created after the provided time frame are actually
3058 announced. Affected file silcd/server.[ch].
3060 * The protocol says that the Channel ID's IP address must be
3061 based on the router's IP address. Added check for this in
3062 the silc_server_new_channel when processing incoming New Channel
3063 Payload. Affected file silcd/packet_receive.c.
3065 * Print out the correct version with --version in SILC client.
3066 Affected file irssi/src/silc/core/silc-core.c.
3068 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3070 * Fixed WHOWAS command to check for completnes of the client
3071 entry always, not just when the command is coming from client.
3072 Affected file silcd/command.c.
3074 * Added new function silc_server_packet_queue_purge to purge the
3075 outgoing data queue to the network. After the function returns
3076 it is guaranteed that the outgoing packet queue is empty.
3077 Affected file silcd/packet_send.[ch].
3079 * Purge the outgoing packet queue in the rekey protocol's final
3080 callback to assure that all rekey packets go to the network
3081 before quitting the protocol. Affected file silcd/server.c.
3083 * Added silc_client_packet_queue_parse as similar function as
3084 in server to the client library. The affected file is
3085 lib/silcclient/client.c.
3087 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3089 * Splitted silcd/server.c and created silcd/server_util.[ch]
3090 for utility functions.
3092 * Added new socket flag SILC_SF_DISABLED to indicate that the
3093 connection is open but nothing can be sent to or received from
3094 the connection. Affected file lib/silcutil/silsockconn.[ch].
3095 The checking for disabled socket is checked in the low level
3096 silc_socket_write and silc_socket_read functions.
3098 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3100 * Allow only nicknames and channel names that fits into the
3101 7-bit unsigned char ASCII set. Affected file silcd/command.c.
3103 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3105 * When processing JOIN command reply in server check that if
3106 the channel exists in our global list we'll move it the local
3107 list. Affected file silcd/command_reply.c.
3109 * Fixed the check whether client is joined on the channel already
3110 in JOIN command. Affected file lib/silcclient/command.c.
3112 * Fixed the JOIN command reply to check whether the channel
3113 already exists. Affected file lib/silcclient/command_reply.c.
3115 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3117 * Added silc_ske_status_string to map the SKE error numbers
3118 to readable strings. The affected files are
3119 lib/silcske/silcske[_status].[ch].
3121 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3123 * Do not show the private channels on the WHOIS channel list
3124 as it is not allowed by the protocol. The affected file is
3127 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3129 * Assure that the packet length digged from the actual packet
3130 is something sensible in the silc_packet_decrypt_rest_special
3131 in lib/silccrypt/silcpacket.c.
3133 * Free and NULL the allocated pointer in silc_hmac_alloc if
3134 the HMAC allocation fails. The affected file is
3135 lib/silccrypt/silchmac.c.
3137 * Print the selected security properties to the log files in
3138 the server. Affected file silcd/protocol.c.
3140 * Add SKE's reference counter even if calling the completion
3141 callback manually. Otherwise it goes negative, although it
3142 does not cause any problems. The affected file is
3143 lib/silcske/silcske.c.
3145 * Remove the client entry with short timeout after giving the
3146 KILL command. Affected file lib/silcclient/command.c.
3148 * Fixed to send error reply in WHOIS and IDENTIFY commands in
3149 case all found clients are already disconnected (WHOWAS would
3150 found them) in the server. Affected file silcd/command.c.
3152 * Update the last_receive (time of last data received) to be
3153 updated only when received private or channel message so that
3154 the idle time showed in WHOIS makes more sense.
3156 * Added boolean field `valid' in to the SilcClientEntry in the
3157 client library to indicate whether the entry is valid or not.
3158 This fixes the nickname change bug on channel when changing
3159 the nickname to be same than the old (like nick to Nick) the
3160 nickname formatter doesn't set the new nick anymore to Nick@host.
3161 Affected file lib/silcclient/idlist.[ch].
3163 * Now actually fixed the nickname changing on disconnection.
3164 Added new function silc_change_nick to the Irssi SILC Client.
3165 Affected file irssi/src/silc/core/client_ops.c,
3166 irssi/src/silc/core/silc-nicklist.[ch].
3168 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3170 * Check that the public key exists in the GETKEY command before
3171 trying to encode it. Affected file silcd/command.c.
3173 * Print some notifications on received public keys with GETKEY
3174 command in the Irssi SILC Client. Affected files are
3175 irssi/src/fe-common/silc/module-formats.[ch],
3176 irssi/src/silc/core/client_ops.c.
3178 * Use IDENTIFY command to resolve the server information in the
3179 GETKEY command instead of INFO command. Affected file
3180 lib/silcclient/command.c.
3182 * All command reply functions in the client library now calls
3183 the pending command reply callbacks even if an error has
3184 occurred. The server has done this a long time and now it was
3185 time to move the client library to this as well. Now all
3186 errors can be delivered back to the pending command reply
3187 callbacks if necessary. Affected files are
3188 lib/silcclient/command[_reply].[ch].
3190 * Change the nickname on disconnection back to the username
3191 because in reconnect the server will enforce it to it anyway.
3192 Affected file irssi/src/silc/core/silc-servers.c.
3194 * Fixed a config file parsing bug in the Irssi SILC client.
3195 Affected file irssi/src/silc/core/clientconfig.c.
3197 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3199 * When printing the channel mode on JOIN, verify that the
3200 channel key and channel's HMAC are valid. Affected file
3201 irssi/src/silc/core/client_ops.c.
3203 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3205 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
3206 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
3207 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
3209 * Removed channel key rekey task deleting from the function
3210 silc_server_save_channel_key. Affected file silcd/server.c.
3211 Added explicit timeout task context instead that is used to
3212 delete the task if we are registering a new task before the
3213 new task has elapsed.
3215 * When channel key rekey occurs the client library now saves
3216 the old channel key for a short period of time (10 seconds) and
3217 is able to use it in case some is still sending channel
3218 messages encrypted with the old key after the rekey. Affected
3219 file lib/silcclient/[idlist.h|client_channel.c].
3221 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3223 * Added check to the silc_server_new_id_real to not accept
3224 new ID if it is the sender's own ID. Affected file is
3225 silcd/packet_receive.c.
3227 * Assure that we do not announce ourself or the one we've
3228 sending our announcements when we're router and are announcing
3229 servers to our primary router. Affected file silcd/server.c.
3231 * Fixed silc_server_command_identify_check_client to assemble
3232 correct WHOIS packet. It send corrupted WHOIS packet and
3233 caused problem with router to router connections. Affected
3234 file silcd/command.c.
3236 Fixed also silc_server_command_whois_check the same way
3237 as for the IDENTIFY command.
3239 * Added new SilcIDListStatus to the server in the SilcIDListData
3240 structure. The status now includes the current status of
3241 the entry (like registered, resolved etc.). Affected file
3242 silcd/idlist.[ch]. Defined a bunch of different status types
3243 as well. This replaced the old boolean registered field as well.
3245 Added resolve_cmd_ident field to the SilcClientEntry structure
3246 too so that if the entry is for example being resolved so
3247 another command may attach to the same pending command reply
3248 without requiring to resolve the same entry again. This concept
3249 should optimize the WHOIS and the IDENTIFY resolving under
3250 heavy load by taking away unnecessary resolving for entries
3251 that are being resolved already.
3253 Added support for adding multiple pending commands for one
3254 command idenfier. Affected file silcd/command[_reply].[ch].
3256 * Fixed WHOIS and IDENTIFY save to remove the cache entry
3257 before deleting the data. Otherwise the hash table will have
3258 freed data in comparison functions. Affected file is
3259 silcd/command_reply.c.
3261 * Fixed silc_idlist_replace_client_id to add the new entry to
3262 the cache with NULL nickname. Otherwise there will be invalid
3263 memory as the nickname after the nickname is freed. Affected
3264 file silcd/packet_receive.c.
3266 * Fixed the silc_idlist_get_clients_by_hash. The entries was
3267 saved into wrong slots because the previous number of entries
3268 was not taken into account. Affected file silcd/idlist.c.
3269 Fixed same thing in silc_idlist_get_clients_by_nickname too.
3271 * If we are router and we receive JOIN notify to a channel that
3272 does not have any users then notified client is marked as the
3273 channel founder, as it is it. The affected file is
3274 silcd/packet_receive.c
3276 * Added to the extended hash table API's table_del_*ext functions
3277 the destructor as argument too, so that the caller can decide
3278 which destructor to use or whether to use destructor at all.
3279 Affected file lib/silcutil/silchashtable.[ch].
3281 * Fixed ID Cache purging. It actually deleted the entries from
3282 the hash table after the data was freed. The hash table ended
3283 up comparing freed memory. The affected file is
3284 lib/silccore/silcidcache.c.
3286 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3288 * Fixed Irssi SILC client's KILL command's HELP syntax.
3290 * The USERS command now resolves the detailed user information
3291 if the userinfo field is missing. Affected file is
3292 lib/silcclient/command_reply.c.
3294 * Do not print error in silc_file_read if the read file does
3295 not exist. Just silently return NULL. Affected file is
3296 lib/silcutil/silcutil.c.
3298 * Fixed the silc_log_output to not wine about NULL filename
3299 and to not create some bogus " " filename. Affected file is
3300 lib/silcutil/silclog.c.
3302 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3304 * Fixed various printing bugs on the user interface in the
3305 Irssi SILC Client. Minor changes that were forgotten from
3308 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3310 * Fixed the configure.in.pre and the compilation and distribution
3311 environment to support the new autoconf 2.52. That version is
3312 now required to compile the CVS trunk.
3314 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3316 * Renamed function silc_parse_nickname to silc_parse_userfqdn
3317 to generally parse user@fqdn format strings. Affected file
3318 lib/silcutil/silcutil.c.
3320 * Added nickname_format and nickname_force_format fields to the
3321 SilcClientParams structure. The first one defines the format
3322 for the nicknames that the library will enforce if the receives
3323 multiple same nicknames. The second one is boolean value and
3324 can be used to force the library to always enforce the format
3325 to the nicknames regardles whether there are multiple nicknames
3326 or not. This configurable formatting was employed to flexibly
3327 support accessing multiple nicknames from the user interface.
3328 The userinterface can now set the nicknames to what ever format
3329 they prefer. Affected file lib/silcclient/silcapi.h.
3331 Added function silc_client_nickname_format to the file
3332 lib/silcclient/idlist.c. It performs the nickname formatting.
3334 Added new field `hostname´ to the SilcClientEntry context.
3335 It holds the hostname of the client. Affected file is
3336 lib/silcclient/idlist.h.
3338 * Irssi SILC Client sets the nicknames in nick@hostn format.
3339 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
3340 irssi/src/silc/core/silc-core.c.
3342 The WHOIS printing now also shows both the real nickname and
3343 the formatted nickname so that user knows how to access the
3344 user if there are multiple same nicknames cached. Affected
3345 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
3346 printing formatting too to take the hostname now as a separate
3347 argument. The Affected file is
3348 irssi/src/fe-common/silc/modules-formats.[ch].
3350 * Changed the silc_client_get_clients_local to accept the formatted
3351 nickname as argument. It accepts the real nickname too but the
3352 formatted nickname can be used to find the true entry from
3353 multiple entries. Affected file lib/silcclient/silcapi.h and
3354 lib/silcclient/idlist.c.
3356 * Added nickname_format_parse field to the SilcClientParams.
3357 It is a callback function provided by the application to parse
3358 the nickname out of the formatted nickname string. The library
3359 calls it to get the nickname from the formatted string. Since
3360 the application generally knows better the format of the nickname
3361 string it parses it instead of the library, even though library
3362 encodes the formatted string. If the callback function is not
3363 provided then the library will use the string as is. The
3364 affected file is lib/silcclient/silcapi.h.
3366 * All the nickname strings passed to the client library in
3367 commands are now expected to be formatted nickname strings.
3368 If the command does not support the formatted nickname string
3369 it will assume that the sent string is the actual nickname.
3370 Affected file lib/silcclient/command.c.
3372 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3374 * Added public key authentication support to OPER and SILCOPER
3375 commands in the client library. Affected file is
3376 lib/silcclient/command.c.
3378 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3380 * Changed the get_auth_methdod client operation to be asynchronous.
3381 It can be async if the application resolves the authentication
3382 method from the server during the negotiation. Added new
3383 SilcGetAuthMeth completion callback that the application will
3384 call after resolving the authentication method.
3386 Added function silc_client_request_authentication_method that
3387 the application can use to resolve the authentication method
3388 from the server. Added also SilcConnectionAuthRequest callback
3389 that the library will call after the server has replied. The
3390 application can call this function if it does not know the
3391 current authentication method.
3393 Affected files are lib/silcclient/client.c and
3394 lib/silcclient/silcapi.h.
3396 * The Irssi SILC client now automatically resolves the authentication
3397 method incase any configuration information is not present (and
3398 currently there never is). The affected file is
3399 irssi/src/silc/core/client_ops.c.
3401 * Fixed public key authentication from the client library.
3402 Affected file lib/silcclient/protocol.c. Changed also the
3403 protocol specification about the public key authentication in
3404 the connection authentication protocol. The actual data to be
3405 signed is now computed with a hash function before signing.
3407 * Fixed the public key authentication from the server as well.
3408 Affected file silcd/protocol.c.
3410 * Removed the mlock()'s from the memory allocation routines.
3411 Affected file lib/silcutil/silcmemory.c. The ./configure does
3412 not check anymore for the mlock(). Affected file is
3415 * Fixed USERS command in server to allow the execution of the
3416 command for private and secret channels if the client sending
3417 the command is on the channel. Affected file silcd/command.c.
3419 * Fixed silc_client_get_clients_local to return the clients
3420 count correctly. It could return wrong value. Affected file
3421 lib/silcclient/idlist.c.
3423 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3425 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
3426 types. The assembler optimizations seemed not to like 64-bit
3427 data types. The assmebler optimizations thus are now enabled
3428 also for BSD systems as opposed to only enable them for Linux.
3430 * Do not check for threads at all on BSD systems. Affected
3431 file configure.in.pre.
3433 * Removed -n and -h options from the Irssi SILC Client since
3434 they are not used in silc.
3436 * Fixed the prime generation to assure that the first digit
3437 of the generated random number is not zero since our conversion
3438 routines does not like number strings that starts with zero
3439 digit. If zero digit is seen the random number is regenerated.
3440 This caused some corrupted RSA keys when the zero first digit
3441 was met. Affected file lib/silcmath/silcprimegen.c.
3443 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3445 * Fixed WIN32 configuration in the ./configure script.
3446 Fixed to include xti.h on environments that has it.
3447 Patches by Carsten Ilchmann and andrew.
3449 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3451 * Changed the silc_id_create_client_id to be collision
3452 resistant. It is now assured that there cannot be created
3453 two same client ID's. I suspect that some weird bugs in
3454 the server were actually caused by duplicate Client IDs.
3455 Affected file silcd/serverid.[ch]. A router receiving
3456 new ID now also assures and informs the sending server
3457 if the ID caused collision.
3459 * Changed the silc_id_create_channel_id to also assure that
3460 there are no collisions.
3462 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3464 * Statement about ignoring the Mutual Authentication flag when
3465 performing rekey with PFS was a bit misleading. It is ignored
3466 if it was set in the initial negotiation, it cannot be even
3467 set in the rekey. Fixed in the ke-auth draft. Started the
3468 new versions of the protocol drafts in the doc/.
3470 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3472 * Fixed a bug in silc_client_command_identify_save when saving
3473 new channel information. The channel name was no duplicated
3474 and caused crash on exit. Affected file is
3475 lib/silcclient/command_reply.c.
3477 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3479 * Fixed the getkey command handling in the server. Send just
3480 empty OK reply to the sender if the key could not be fetched
3481 (but everything else was ok, like the key just was not available).
3482 Changed the public key parameter to optional in the protocol
3483 specs so that empty OK reply can be sent. Affected file
3486 Added a message to Irssi SILC client to tell to user if the
3487 server did not return a public key.
3489 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3491 * Fixed a channel key regeneration bug. It registered new
3492 timeout tasks exponentially until all system resources were
3493 used. Affected file silcd/server.c.
3495 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3497 * Added the SILC Document generator to the scripts/silcdoc.
3498 It can be used to generate the Toolkit Reference Manual out
3499 of the source tree. Internally it will also use the RoboDoc
3500 generator now imported in util/robodoc.
3502 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3504 * Added couple of return's in rekey protocol if error orccurred
3505 during the protocol. The execution must be terminated.
3506 Affected file silcd/protocol.c. Also, terminate the protocol
3507 always with timeout.
3509 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3511 * The client's Client ID was created initally from the wrong
3512 nickname (it could have been in format nick@host) in the
3513 silc_server_new_client. Affected file silcd/packet_receive.c
3515 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3517 * Added some SILC_LOG_ERROR's to various error conditions
3518 if client could not be added to ID cache. Affected files
3519 silcd/packet_receive.c and silcd/server.c.
3521 * When client's sock->user_data is freed, NULL also the
3522 client->router and client->connection pointers. Added check
3523 for these pointers being NULL to various places around the
3524 code. Affected file silcd/server.c.
3526 * Added client->data.registered == TRUE checks to various
3527 places around the code to assure that unregistered client's
3528 are not handled when it is not allowed. Affected file
3531 * Added `bool registered' fields to all
3532 silc_idlist_[server|client]_get_* routines to indicate whether
3533 the fetched client needs to be registered or not. Affected
3534 file silcd/idlist.[ch].
3536 * Add your own entry as registered to the ID cache in the
3537 server. Affected file server.c.
3539 * Fixed a bug in silc_server_new_server. The SilcServer was
3540 set as the new server's context instead of SilcServerEntry.
3541 This naturally caused some weird bugs.
3543 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3545 * Do not delete the channel rekey task when adding it
3546 for in silc_server_create_channel_key.
3548 * Changed the silc_server_create_channel_key to return
3549 TRUE or FALSE to indicate the success of the channel key
3552 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3554 * Fixed MSVC++ project files and added missing files to
3555 Makefiles under win32/.
3557 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3559 * Do not add TCP_NODELAY flag if the operating system
3560 does not have it defined. Affected files are
3561 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3563 * Fixed buffer overflow from Irssi SILC Client. Affected
3564 file irssi/src/fe-common/core/themes.c.
3566 * Fixed double free in client library in the file
3567 lib/silcclient/client.c when disconnecting from server.
3569 * Applied double free patch from cras to Irssi SILC client.
3570 Affected files irssi/src/core/[modules/expandos].c
3572 * Fixed the disconnection handling to Irssi SILC Client.
3573 The application must call silc_client_close_connection
3574 in ops->connect client operation in case of failure of
3575 the connection. Affected file is
3576 irssi/src/silc/core/client_ops.c.
3578 * Do not set sock->protocol to NULL in the function
3579 silc_client_close_connection after executing the protocol's
3580 final callback since the sock might not be valid anymore.
3581 Affected file lib/silcclient/client.c.
3583 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3585 * Do not enable SILC_THREADS if the linking with libpthread
3586 did not happen. Affected file configure.in.pre.
3588 * Added notion to protocol specification that server must
3589 verify the sent authentication payload with CMODE when
3590 setting the channel founder key. Implemented it to the
3591 server. Affected file silcd/command.c.
3593 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3595 * Added _EXTRA_DIST SILC distribution variable to the
3596 distributions file. It is used to conditionally add extra
3597 files or directories to the specific distribution. Affected
3598 files ./prepare, Makefile.am.pre and distributions.
3600 Removed the `_' from the start of the distribution names.
3603 * Added README.WIN32 for instructions to compile the Toolkit
3606 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3608 * Fixed a double free in disconnection in the server. Affected
3609 file is silcd/server.c.
3611 * Fixed the lib/silcske/groups.c to work now also with GMP
3612 MP library. The string conversion did not work when using
3613 specific base and the base is indicated in the string as well.
3615 * Created win32/ directory which now includes MSVC++ specific
3616 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3617 It will appear only in the toolkit distribution
3619 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3621 * Changed the key material distribution function in case when
3622 the hash output is too short. The data is now concatenated
3623 a bit differently than it used to. Made the change to the
3624 SKE protocol specification.
3626 * Added better GMP detection to configure.in.pre. A patch
3629 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3631 * Fixed a minor bug in SKE that might cause some problem on
3632 some platforms. Affected file lib/silcske/silcske.c.
3634 * Added the cookie checking for initiator in the SKE. It checks
3635 that the responder returns the sent cookie unmodified. The
3636 affected file is lib/silcske/silcske.c. Added new SKE
3637 error type INVALID_COOKIE that can be sent during the
3638 negotiation. Fixed some memory leaks as well.
3640 * Added the "invalid cookie" error message to Irssi SILC client's
3643 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3645 * Added `task_max' field to the SilcClientParams to indicate
3646 the maximum tasks the scheduler can handle. If set to zero,
3647 default values are used. Affected file lib/silcclient/silcapi.h.
3649 * Fixed memory leaks in silc_client_close_connection. Affected
3650 file lib/silcclient/client.c.
3652 * Added silc_client_del_client_entry to client library to free
3653 all memory of given client entry. Affected file is
3654 lib/silcclient/idlist.[ch].
3656 * Added new functions silc_client_del_channel and
3657 silc_client_del_server to delete channel and server entries.
3658 Affected file lib/silcclient/[silcapi.h/idlist.c].
3660 * Removed silc_client_del_client_by_id from silcapi.h.
3662 * Fixed the INFO command to return the server's own info
3663 correctly when querying by Server ID. Affected file is
3666 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3668 * Removed the non-blocking settings in WIN32 code in the
3669 silc_sock_[read/write] and added SleepEx instead. Affected
3670 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3671 of input data is now checked with FIONREAD and ioctlsocket.
3673 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3675 * Call silc_schedule_task_del_by_context in the
3676 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3677 Affected file lib/silccore/silcprotocol.c.
3679 * Call silc_protocol_cancel for active protocols in the
3680 silc_server_close_connection if the funtion
3681 silc_server_free_sock_user_data has not been called.
3682 Affected file silcd/server.c.
3684 * Generic tasks cannot be deleted using the del_by_fd
3685 task deleting function since generic tasks does not match
3686 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3688 * Added a notion to SILCOPER help file that the SILCOPER works
3689 only on router server, not on normal server.
3691 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3693 * Added for WIN32 support for the new scheduler as well.
3694 Affected file lib/silcutil/win32/silcwin32schedule.c.
3696 * Fixed the SHA1 implementation to work on various platforms.
3698 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3700 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3701 API. It is part of the scheduler now. Everything else is
3702 as previously but some functions has changed their names.
3703 Checkout the lib/silcutil/silcschedule.h for the interface.
3704 Updated all applications to use the new interface. Affected
3705 files are lib/silcutil/silcschedule.[ch].
3707 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3709 * Found a bug in the SKE implementation. The HASH value,
3710 specified by the protocol, was not computed correctly. The
3711 public key of the responder was not added to the computation
3712 even though it is mandatory. Affected file lib/silcske/silcske.c.
3713 This unfortunately causes incompatibilities with older
3714 clients and servers.
3716 * Added WIN32 specific network init and uninit functions:
3717 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3718 the Winsock2. Affected file lib/silcutil/silcnet.h and
3719 lib/silcutil/win32/silcwin32net.c.
3721 * Set the socket always to nonblocking mode on WIN32 after
3722 reading data or writing data. Affected file is
3723 lib/silcutil/win32/silcwin32sockconn.c.
3725 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3727 * Fixed various compilation problems under WIN32. Affected
3728 files lib/silcutil/win32/silcwin32thread.c and
3729 lib/silcutil/win32/silcwin32schedule.c.
3731 * Removed all _internal.h #includes from public header
3732 files. Internal headers must never be included from
3735 Removed also the lib/silcske/payload_internal.h file.
3737 * All include files that may be needed (public and some others
3738 included by the public headers) by application developers are
3739 now copied to the ./includes directory. It does not copy any
3740 internal headers. Affected file Makefile.defines.pre and all
3741 Makefile.am's under lib/ and subdirs.
3743 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3745 * Do not change the ~/.silc directory's permissions automatically.
3746 Affected file irssi/src/silc/core/clientutil.c.
3748 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3750 * Do not cancel the protocol in silc_server_close_connection
3751 it might cause recursion. Now cancelled in the function
3752 silc_server_free_sock_user_data. Affected file silcd/server.c.
3754 * Fixed the silc_server_remove_clients_by_server to regenerate
3755 the channel keys correctly finally. Added also new function
3756 silc_server_remove_clients_channels to actually do it.
3757 Affected file silcd/server.c.
3759 * Fixed the silc_server_new_channel to not crash by giving
3760 wrong router to the new channel. Affected file is
3761 silcd/packet_receive.c.
3763 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3765 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3766 which is given as argument to the silc_client_alloc now.
3767 It can be used to configure the client and set various parameters
3768 that affect the function of the client.
3770 * The USERS command in server did not check whether the channel
3771 is private or secret. Affected file silcd/command.c.
3773 * Added new argument to the USERS command in protocol specification.
3774 The USERS command now can take the channel name as argument
3775 as well. Added support for this in client and server and
3776 updated the protocol specs.
3778 * Completed the GETKEY command in client. It can be now used
3779 to fetch also servers public key not only some clients.
3780 Affected files lib/silcclient/command[_reply].c.
3782 * Added silc_client_get_server to return server entry by the
3783 server name. Affected files lib/silcclient/silcapi.h and
3786 * Redefined the IDENTIFY command in protocol specification to be
3787 more generic. It now can be used to query information about
3788 any entity in the SILC Network, including clients, servers and
3789 channels. The query may be based either the entity's name
3790 or the ID. Added support for this in both client and server.
3792 Affected files silcd/command.c and lib/silcclient/command.c
3793 and command_reply.c.
3795 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3796 the _from_client and _from_server functions. Affected file
3799 * Added silc_client_get_channel_by_id_resolve to the file
3800 lib/silcclient/silcapi.h to resolve channel information by
3801 its ID. Added also silc_client_get_channel_by_id that
3802 does not resolve it from the server.
3804 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3806 * Added SilcServerEntry context into the client library
3807 to represent one server. The INFO command now allocates
3808 these to save the resolved server info. For now on the
3809 client library will also keep information about servers,
3810 connected and resolved with INFO.
3812 The INFO command now allocates the SilcServerEntry context
3813 and saves the server info there. The COMMAND_REPLY in
3814 the INFO now returns the parameters to application in
3815 same order as defined in the protocol specification.
3817 The entries are cached in the client->server_cache.
3819 * The INFO command is now issued after received the Client ID
3820 from the server. Affected file lib/silcclient/client.c.
3822 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3823 to the application as the mode changer might be server.
3824 It is guaranteed that NULL is not returned anymore to the
3825 application. Affected file lib/silcclient/client_notify.c.
3827 The ID Type is now also passed to the application so that
3828 it can check whether the returned entry is SilcClientEntry
3831 Added new function silc_client_get_server_by_id to return
3832 the server entry by ID. Affected files are the
3833 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3835 * Do not create the channel in the Irssi SILC Client when issuing
3836 the JOIN command but when received the sucessful JOIN command
3837 reply. Otherwise the channel might get created even though we
3838 could not join it. The Affected file is
3839 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3841 * Fixed a channel joining bug in router. The router must also
3842 check the channel modes, invite and ban lists etc. when serving
3843 the JOIN command sent by normal server. Affected file is
3844 silcd/command.c. The router now resolves the client's
3845 information from the server who sent the JOIN command if it
3846 does not know it, and processes the JOIN command only after
3849 * Changed the SilcCommandCb to take new argument; void *context2.
3850 Affected file lib/silccore/silccommand.h
3852 The second argument in the command callbacks in the server now
3853 includes the SilcServerCommandReplyContext if the command was
3854 called as pending command callback from the command reply.
3855 Otherwise it is NULL. When called as pending the status of the
3856 command reply will be checked and if it was erronous the
3857 error will be sent to the original sender of the command.
3858 This way the client always receives the error messages even
3859 though the server was actually the one who received the error
3860 when it resent the command to router, for example. Affected
3861 files silcd/command[_reply].[ch].
3863 * Fixed sending WHOWAS command's error message to client if
3864 the requested client could not be found. It was missing.
3867 * Changed the CMODE and CUMODE commands reply arguments in the
3868 protocol specification. The Channel ID is now sent in both
3869 of the commands to identify the channel. Implemented this
3870 new feature to the client and server. Affected files
3871 lib/silcclient/command_reply.c and silcd/command.c.
3873 * Made better checks for invite and ban lists in the JOIN
3874 command in server. Affected file silcd/command.c.
3876 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3878 * The server now performs the incoming host IP/DNS lookup
3879 using the silc_socket_host_lookup and thus does not block
3880 the server anymore. Affected file silcd/server.c.
3882 * Completed the multi-thread support for SILC Scheduler in
3883 the lib/silcutil/silcschedule.c.
3885 * Fixed the configure.in.pre to detect the pthread correctly
3888 * Fixed a deadlock in silc_task_queue_wakeup in the file
3889 lib/silcutil/silctask.c.
3891 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3893 * Added new function silc_schedule_wakeup that is used in
3894 multi-threaded environment to wakeup the main thread's
3895 schduler. It needs to be used when a thread adds a new task
3896 or removes a task from task queues. After waking up, the
3897 scheduler will detect the task queue changes. If threads
3898 support is not compiled in this function has no effect.
3899 Implemented the wakeup mechanism to both Unix and WIN32
3900 systems. Affected files are lib/silcutil/silcschedule.[ch],
3901 lib/silcutil/unix/silcunixschedule.c and the
3902 lib/silcutil/win32/silcwin32schedule.c.
3904 * Added new function silc_task_queue_wakeup to wakeup the
3905 scheduler by the specified task queue. Affected file
3906 lib/silcutil/silctask.[ch].
3908 * The silc_socket_host_lookup_start now wakes up the scheduler
3909 after adding the timeout task. Affected file is
3910 lib/silcutil/silcsockconn.c.
3912 * The silc_socket_host_lookup is synchronous now if the threads
3913 support is not compiled in. However, the callback is still
3914 called asyncronously through the scheduler, anyway. Affected
3915 file lib/silcutil/silcsockconn.c.
3917 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3919 * Added new function silc_socket_host_lookup to perform
3920 asynchronous IP and FQDN lookups for the socket connection.
3921 Affected files lib/silcutil/silcsockconn.[ch].
3923 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3925 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3926 that may or may not compile the mutex support in.
3928 Changed the silc_mutex_alloc interface. It allocates the
3929 mutex now to the sent pointer and returns TRUE or FALSE.
3931 Affected file lib/silcutil/silcmutex.h.
3933 * Wrote the SILC Task Queue interface to support multi-threads.
3934 Affected file lib/silcutil/silctask.[ch].
3936 * Wrote the SILC Scheduler to support multi-threads. Affected
3937 file lib/silcutil/silcschedule.c.
3939 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3941 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3942 in lib/silcutil/win32/.
3944 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3946 * Defined SILC Mutex API and SILC Thread API and implemented
3947 them for Unix. Affected files are
3948 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3949 lib/silcutil/unix/silcunixmutex.c and
3950 lib/silcutil/unix/silcunixthread.c.
3952 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3954 * Fixed the silc_server_remove_clients_by_server's channel
3955 key re-generation. The hash table handling was incorrect
3956 and would not work with many channels. Affected file is
3959 * Fixed some memory leaks around the server code.
3961 * Rewrote the silc_server_get_users_on_channel to support IPv6
3962 based Client ID's. Affected file silcd/server.c.
3964 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3965 specification. However, a separate document must be written
3966 to define the detailed signing procedure and the payload
3967 associated with the flag. Defined the flag to the
3968 lib/silccore/silcchannel.h as well.
3970 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3972 * Changed the dynamic tables to static size tables in the
3973 lib/silccrypt/silchmac.c.
3975 * Removed GCC dependencies from the code. A patch by cras.
3977 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3979 * Do not show the error "Error receiving packet bla bla"
3980 in server if it really was not an error (-2 means that reading
3981 is pending). Affected file silcd/server.c.
3983 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3985 * Fixed a possible crash in silc_server_remove_clients_by_server
3986 in silcd/server.c. Fixed there also some memory leaks.
3988 * Fixed the silc_idlist_replace_client_id. It could replace
3989 wrong key in the hash table. Affected file silcd/idlist.c.
3991 * Do not check whether there are global users on the channel
3992 if the channel->global_users is FALSE. Affected functions
3993 silc_server_remove_from_one_channel and
3994 silc_server_remove_from_channels in silcd/server.c. Also,
3995 do not check if the removed client is local as we can be
3996 sure that global client was not removed from the channel
3997 and checking for global users is not needed.
3999 * The silc_server_remove_clients_by_server now re-generates
4000 the channel keys correctly for those channels that had
4001 clients removed from them. Affected file silcd/server.c.
4003 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4005 * Found the reason of random crashes in the server. We weren't
4006 ignoring the SIGPIPE signal (which can be sent in write())
4007 and it crashed the server. Affected file silcd/silcd.c.
4009 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4011 * Assure that sock->user_data is not NULL in the function
4012 silc_server_packet_send in silcd/packet_send.c.
4014 * Disconnect the remote connection if it could not be added
4015 to any ID lists in the server. The affected file is
4018 * Check in silc_server_packet_send[_real/dest] that the
4019 socket is not disconnecting and ignore the data if it is.
4020 Affected file silcd/packet_send.c.
4022 * Define inline to __inline on native WIN32 compilation.
4023 Affected file includes/silcwin32.h.
4025 * Added some explicit type casts for inline code since MSVC
4026 require them. Affected files lib/silcutil/silcbuffer.h,
4027 lib/trq/silcdlist.h and lib/trq/silclist.h.
4029 * Print warning in log files from now on if the packet
4030 decryption fails. Affected file silcd/server.c.
4032 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4034 * Changed the `say' client operation's interface to accept
4035 new `type' argument to indicate the type of the message sent
4036 by the library. The application may filter the library's
4037 messages according the type. The affected file is the
4038 lib/silcclient/silcapi.h.
4040 * Added two new functions to lib/silcclient/silcapi.h:
4041 silc_client_del_client and silc_client_del_client_by_id.
4042 Affected file lib/silcclient/idlist.c.
4044 * Moved the clientincludes.h from includes/ to silc/ and
4045 serverincludes.h from includes/ to silcd/.
4047 * The modes for the CMODE and CUMODE are now passed as
4048 uint32 for application with COMMAND_REPLY. The affected
4049 file is lib/silcclient/command_reply.c.
4051 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4053 * /WHOIS without arguments shows client's own information.
4054 Affected file lib/silcclient/command.c.
4056 * Changed PING to not accept any arguments. The specs
4057 says that client can ping only the connected server so
4058 requiring an argument is not needed. Affected file is
4059 lib/silcclient/command.c.
4061 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4063 * Fixed a fatal bug in private message sending and reception
4064 encryption and decryption when using private message keys.
4065 The implementation was incorrect and did not follow the
4066 specification. It causd that some of the message were
4067 lost since it did not use the sending and receiving keys
4068 as the protocol suggests. This has been fixed and will cause
4069 incompatibilities with older clients when sending private
4070 message encrypted with private message keys. Affected files
4071 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
4072 and various other in Irssi SILC Client.
4074 Added `responder' boolean argument to the functions
4075 silc_client_add_private_message_key[_ske] to indicate when
4076 the key is added as responder or initiator of the key
4079 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4081 * Removed the silc_ske_check_version function and created
4082 a SilcSKECheckVersion callback. Added also a function
4083 silc_ske_set_callbacks that is now used to set all SKE
4084 callbacks. The callback functions are not given to
4085 the SKE functions anymore, but this function is used to
4088 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
4090 * Added `silc_version' argument to the silc_client_alloc
4091 to define the version of the application for the library.
4092 The library will use the version string to compare it
4093 against the remote host's (usually a server) version
4094 string. Affected file lib/silcclient/silcapi.h
4096 * Added the KE protocol context to Key Agreement context
4097 in client library so that we can abort the SKE if it
4098 is in process when we get timeout. Affected file is
4099 lib/silcclient/client_keyagr.c.
4101 * Do not resolve the client ID forever if it returns in the
4102 first time that such client does not exist. This was done
4103 for example with private message. Affected file is
4104 lib/silcclient/client_prvmsg.c.
4106 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4108 * Do not add regex.h for WIN32. The affected file
4109 includes/silcincludes.h.
4111 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
4112 not work yet 100%. It generates the DLL's automatically
4113 when compiling with --with-win32 under cygwin.
4115 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4117 * lib/contrib/regex.c is not compiled on WIN32.
4119 * Added silc_net_get_socket_opt function to the
4120 lib/silcutil/silcnet.h.
4122 * Added includes/silcwin32.h for WIN32 specific includes
4125 * Do not use ptime structure or any of the posix process
4126 functions on WIN32 in lib/silccrypt/silrng.c.
4128 * Added silc_gettimeofday to provide generic function
4129 for struct timeval on all platforms. Added the function
4130 to lib/silcutil/silcutil.h.
4132 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4134 * Moved the lib/silccore/silcsockconn.[ch] to the utility
4135 library as they clearly belong there. As a plus side we
4136 can make the actual socket connection routines platform
4139 Added also new generic function silc_socket_read and
4140 silc_socket_write (that used to be silc_packet_[read/write].
4141 The implementation of these are platform specific.
4143 * Added WIN32 specific routines of silc_socket_[read/write]
4144 to lib/silcutil/win32/silcwin32sockconn.c.
4146 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4148 * Added preliminary support for native WIN32 compilation under
4149 cygwin (using the -mno-cygwin option for GCC) to the
4150 ./configure.in.pre. The --with-win32 now prepares the
4151 compilation for native WIN32.
4153 * Rewrote the SILC Scheduler interface in the file
4154 lib/silcutil/silcschedule.h. The scheduler is now context
4155 based and does not have anymore any global static scheduler.
4156 Moved the Unix scheduler to the lib/silcutil/unix/ directory
4157 and created lib/silcutil/win32 directory for WIN32 based
4160 * Added Unix specific network routines to the
4161 lib/silcutil/unix/silcunixnet.c and the old
4162 lib/silcutil/silcnet.c includes now only generic routines.
4164 Added WIN32 specific network routines to the
4165 lib/silcutil/win32/silcwin32net.c.
4167 * Added Unix specific utility functions from the
4168 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
4170 * Added WIN32 SILC Scheduler to the file
4171 lib/silcutil/win32/silcwin32schedule.c. The code is of course
4174 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4176 * Do not handle JOIN notify in the server if the target client
4177 is not registered (idata->registered == FALSE). The affected
4178 file is silcd/packet_receive.c.
4180 * Update the nickrec->founder in event_cumode in the Irssi SILC
4181 client. Affected file irssi/src/silc/core/silc-channels.c.
4183 * Fixed the CUMODE_CHANGE notify handling in the server when
4184 server and router are announcing their clients on channels.
4185 Now the mode changes are saved and notified correctly. The
4186 affected file is /silcd/packet_receive.c.
4188 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
4189 They really did not replace the cache entry in the ID Cache.
4190 Now they do that. Affected file silcd/idlist.c.
4192 * Fixed the KICK notify handling in the Irssi SILC client to
4193 update the channel records so that the kicked client does not
4194 appear to be on the channel. The affected file is
4195 irssi/src/silc/core/silc-channels.c.
4197 * Always update the conn->current_channel when executing command
4198 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
4200 * Fixed the KILL notify handling in Irssi SILC client to remove
4201 the killed client on all channels.
4203 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4205 * Fixed the silc_parse_command_line to remove extra spaces
4206 from the start and end of the arguments. Affected file is
4207 lib/silcutil/silcutil.c.
4209 * Cancel and free any active protocol in the function
4210 silc_server_close_connection. Affected file silcd/server.c.
4212 * Cancel and free any active protocol in the function
4213 silc_client_close_connction. Affected file is
4214 lib/silcclient/client.c.
4216 * Do not execute the KILL command for clients that are in
4217 history (ie. they are not in the network). Affected file is
4220 * Fixed KILL notify handling, client does not crash anymore.
4221 Affected file irssi/src/silc/core/silc-channels.c.
4223 * Reduced the default packet buffer size from 2048 to 1024 in
4224 lib/silccore/silcpacket.c.
4226 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
4227 counter to the SKE context that is incresed when the SKE library
4228 performs async operation outside the library. If the outside
4229 process frees the SKE context and FREED status will be set
4230 and the library will detect after the sync operation that the
4231 libary is freed. The affected files are
4232 lib/silcske/silcske[_status].[ch].
4234 * Resolve the client entry information in the function
4235 silc_client_channel_message to assure that NULL pointer is not
4236 passed as client entry to the application. */
4238 * Fixed the task timeout calculation to assure that there is
4239 never negative timeouts. The affected file is
4240 lib/silcutil/silcschedule.c.
4242 * Fixed the channel user mode notification sending in server.
4243 It was sent point-to-point to the router (or to server by router)
4244 but it needs to be destined to a channel. The routines now
4245 supports sending the channel user mode notifys to the channels
4246 when announcing clients and channels. Affected files are
4247 silcd/server.c and silcd/packet_receive.c.
4249 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
4250 It did not actually replace the old channel entry in the cache.
4251 Affected file lib/silcclient/client_notify.c.
4253 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4255 * Fixed a possible crash in silc_packet_send_prepare. It now
4256 assures always that there is enough space in the buffer and
4257 at the tail area of the buffer (for MAC).
4259 Fixed the inbound buffer reallocation in silc_packet_read.
4260 It was old code and did not handle the reallocation correctly.
4263 The affected file is lib/silccore/silcpacket.c.
4265 * Fixed buffer overflow in silc_parse_nickname in the file
4266 lib/silcutil/silcutil.c.
4268 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4270 * make install generates new server keys only if there is not
4273 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4275 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
4276 Added check that if the NOREPLY is set then we will not send
4277 the away message. This avoids infinite loop of away messages
4278 if both clients are away. The affected file is
4279 lib/silcclient/client_prvmsg.c.
4281 * Fixed client crash if /NICK was given without arguments.
4282 Affected file lib/silcclient/command.c.
4284 * Server does not send the invite list in INVITE command back
4285 to the client if the list was not altered. Added this notion
4286 to the protocol spec as well. Affected file silcd/command.c.
4288 Fixed possible crash in INVITE command by checking the
4289 value of silc_server_get_client_route command.
4291 * Fixed the INVITE notify type handling. The arguments are now
4292 taken in correct order and client does not crash. The affected
4293 file is irssi/src/silc/core/silc-channels.c.
4295 Removed the "Inviting xxx to channel" message from the
4296 client library away and let the application handle it.
4297 Affected file lib/silcclient/command.c. Added that message
4298 to Irssi SILC client's message formats.
4300 * Fixed CMODE command crash in client. It now checks the
4301 amount of arguments correctly and does not crash. The affected
4302 file is lib/silcclient/command.c.
4304 * Do not create new channel automatically in silc_channels_join
4305 but check whether the channel by that name already exists.
4306 Affected file irssi/silc/core/silc-channels.c.
4308 * Do not send the SERVER_SIGNOFF to router if the disconnected
4309 entity was the router. Affected file silcd/server.c.
4311 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
4312 SILC client as it was missing from there.
4314 Added the handling of the KICK notify to the Irssi SILC client
4315 as it was missing. Added "you have been kicked" message to
4316 Irssi SILC client's message modules formats.
4318 Added the handing of the KILL notify to the Irssi SILC client
4319 as it was missing. Added the kill message module formats
4322 The affected file is irssi/src/silc/core/silc-channels.c.
4324 * The router did not save the channel mode the server announced.
4325 Affected file silcd/packet_receive.c.
4327 * Fixed a possible crash in INFO command in server. If the
4328 server did not provide the server info it crashed. Affected
4329 file silcd/command.c.
4331 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4333 * Fixed the GETKEY command in the server to check also the
4334 global list. Otherwise the GETKEY would not work correctly
4335 in normal SILC server. Affected file silcd/command.c.
4337 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4339 * Fixed GETKEY crash, it crashed if the command did not succseed.
4341 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4343 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
4344 is now real and not just an macro interface to GMP.
4346 Removed the entire GMP from the source tree and imported new
4347 NSS MPI library instead. Reason for removing GMP is that it is
4348 extremely large and compiles extremely slow. The NSS MPI
4349 is only a few files and compiles in less than 10 seconds.
4350 The speed is also about the same as GMP. The MPI is imported
4351 to lib/silcmath/mpi.
4353 If the system has GMP installed we will still use the GMP.
4354 If it is not then the NSS MPI will be compiled.
4356 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4358 * Merged a long nickname (127 characters long) crash bugfix from
4359 Irssi CVS tree. Affected file irssi/src/core/misc.c.
4361 * Merged a freed memory reference bugfix from Irssi CVS tree.
4362 Affected file irssi/src/core/commands.c.
4364 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4366 * Added the server's public key sving and verification to the
4367 server when performing the SKE. This was missing and the
4368 remote server's (or router's) public key was accepted without
4369 checking whether we have it previously or trust it at all.
4370 Affected file silcd/protocol.c.
4372 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4374 * Check in the silc_server_timeout_remote if protocol is active
4375 and make sure that the protocol's final callback is called so
4376 that all memory if freed. Affected file silcd/server.c.
4378 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4380 * silc_server_whois_send_reply crashed the server if the nickname
4381 was 127 characters long. Affected file silcd/command.c.
4383 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4385 * Added sanity check to the silc_server_new_client. If the hostname
4386 is provided inside username then check that the provided hostname
4387 really is the same as the resolved one. If the hostname was not
4388 resolved then check it from the public key. Affected file is
4389 silcd/packet_receive.c.
4391 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
4392 if the server disconnected us and the connection is not valid
4393 anymore. Affected file irssi/src/silc/core/silc-channels.c.
4395 * Moved the silc_client_[chmode|chumode|chumode_char] away from
4396 the library to the lib/silcutil/silcutil.[ch].
4398 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4400 * Close log file after open. Affected file
4401 lib/silcutil/silclog.c.
4403 * Check whether sock == NULL in silc_client_send_packet and return
4404 if it is. Affected file lib/silcclient/silcclient.c.
4406 * Check rec->entry == NULL in the Irssi SILC Client before
4407 sending the channel message. Affecte file is
4408 irssi/src/silc/core/silc-servers.c.
4410 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4412 * Merged a splitted window bugfix from Irssi CVS tree. The
4413 affected file is irssi/src/fe-text/textbuffer-view.c.
4415 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
4416 It did not print nickname.
4418 * Improved the distributions system a bit.
4420 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4422 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
4423 irssi/src/fe-text/gui-window.c.
4425 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
4426 to in-active server. The affected file is
4427 irssi/src/silc/core/client_ops.c.
4429 * Resolve the client in USERS command reply if the entry does
4430 not have username resolved. The affected file is
4431 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
4432 command to WHOIS command to really resolve stuff. The USERS
4433 is not used any more in any critical section so WHOIS can
4434 be used even though it might be slower than IDENTIFY.
4436 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
4439 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4441 * Changed the protocol API a bit more consistent in the
4442 lib/silccore/silcprotocol.[ch].
4444 * Changed the following headers to ROBODoc format:
4446 lib/silccore/silcpayload.h
4447 lib/silccore/silcprotocol.h
4448 lib/silccore/silcsockconn.h
4450 All core library headers are now formatted.
4452 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4454 * Fixed a bug in Irssi SILC client; do not show that you are
4455 server/router operator if you really are not. Affected file is
4456 irssi/src/silc/core/client_ops.c.
4458 * Renamed silc_command_free_payload to silc_command_payload_free.
4459 Affected file lib/silccore/silccommand.h
4461 * Added silcmath.h to include the prototoypes of various routines
4462 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
4465 * Changed the following headers to ROBODoc format:
4467 lib/silccore/silcchannel.h
4468 lib/silccore/silccommand.h
4469 lib/silccore/silcid.h
4470 lib/silccore/silcidcache.h
4471 lib/silccore/silcmode.h
4472 lib/silccore/silcnotify.h
4473 lib/silccore/silcpacket.h
4474 lib/silcmath/silcmath.h
4476 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4478 * Added checking to the server code not to start the server if
4479 ciphers and stuff are not configured properly. Affected files
4480 silcd/serverconfig.[h] and silcd/server.c.
4482 * Changed the layout of the header files of the public interfaces
4483 in the SILC libraries. The new layout supports ROBODoc
4484 documentation tool (and some others) so that it is easy to create
4485 a library reference manual. All the other headers and source
4486 code must still follow the CodingStyle document. Also source
4487 code must not include these ROBODoc stuffs, only the headers.
4488 Furthermore, all public interface headers must now be named
4489 by using `silc' prefix, example: silcapi.h, silccipher.h.
4490 Some files were renamed due to this. All the other headers
4491 must not be used as public interfaces. I will update the
4492 CodingStyle document later. Changed following headers, so far:
4494 lib/silcclient/silcapi.h
4495 lib/silccore/silcauth.h
4496 lib/silccore/silcprivate.h
4497 lib/silccrypt/silcdh.h
4499 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4503 * Removed silc_client_packet_send_flush from the client library
4504 as it is not needed. Affected file lib/silcclient/client.[ch].
4506 * Added printing of message of unresolved authentication method
4507 to the Irssi SILC client. Added it to the module formats.
4508 Removed the same message from the client library.
4510 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4512 * Added new distribution feature, DISTLABEL. Every distribution
4513 can define own preprocessor label that can be used in the
4514 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
4515 file distributions, acconfig.h.pre and prepare.
4517 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4519 * Added Makefile.defines_int to include the actual definitions
4520 for Makefile.defines.in. Tested the new distribution system,
4521 created distributions and tested installation.
4523 * Added AWAY message printing to the Irssi SILC client. Added
4524 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
4526 * Added SCONNECT command to call the SILC's CONNECT command.
4527 Cannot use CONNECT directly since Irssi uses that internally.
4528 Affected file irssi/src/silc/core/silc-servers.c.
4530 Added ACTION local command. It is same as ME command but takes
4531 the channel as mandatory argument.
4533 Rewrote some of the Irssi's help files to suite for SILC
4536 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4538 * Added Makefile.defines[.in] that should for now on be included
4539 in all Makefile.am file in the source tree. That file includes
4540 all common compilation definitions for SILC source tree.
4542 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4544 * Minor changes to the ./prepare script to change the package
4545 name according the distribution name to the configure.in.
4547 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4549 * Created new distribution system. Added file `distributions'
4550 that defines all the distributions that can be created out of
4551 the SILC source tree. The ./prepare script now reads that
4552 file to determine how to prepare the distributions. The
4553 first argument to the ./prepare is the name of the distribution
4554 and second is the version of the distribution. If given
4555 without arguments it creates the default (toolkit) distribution
4556 with the default version (defined in ./prepare).
4558 All Makefile.am files that are subject to the distributions
4559 are now named as Makefile.am.pre. These are ./Makefile.am
4560 and lib/Makefile.am. Others may be changed later.
4562 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4564 * Added invite list, ban list, some key management and connection
4565 error message printing to module formats in the Irssi SILC client.
4567 * Added new silc_client_set_away_message to set the away message
4568 that is back to the person who sent private message. The
4569 affected file lib/silcclient/silcapi.h and the
4570 lib/silcclient/client_prvmsg.c.
4572 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4574 * Fixed the private message sending in the Irssi SILC client,
4575 added local command KEY to the Irssi SILC client.
4577 Added key management and key agreement message formats to the
4578 irssi/src/fe-common/silc/module-formats.[ch].
4580 Added USERS (alias WHO) printing, server/router operator
4581 indication and LIST command printing to the module formats.
4583 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4585 * Fixed channel joining notify handling, cumode notify handling
4586 from Irssi SILC client.
4588 * Added SILC specific module-formats to the Irssi SILC client so
4589 that SILC specific message hilighting, colors etc is possible.
4590 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4592 Added channel mode, channel user mode, actions, notices,
4593 whois and whowas printing to the the module-formats.c.
4595 * Fixed a bug in channel deletion in the server. The channel
4596 is not left to the cache even if the channel founder auth mode
4597 is set when there are no users anymore on the channel. Affected
4598 file silcd/server.c.
4600 * The silc_net_localhost now resolves the entire hostname including
4601 the domain name. Affected file lib/silcutil/silcnet.c.
4603 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4605 * Changed the ask_passphrase client operation to be ascynchronous.
4606 It has now a completion callback and a context that the
4607 application must call after it has got the passphrase from
4608 the user. Affected files lib/silcclient/silcapi.h,
4609 lib/silcclient/protocol.c, lib/silcclient/command.c and
4612 Added SilcAskPassphrase callback that the application calls
4613 to deliver the passphrase to the library.
4615 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4616 The public key verification and especially a certificate
4617 verification is asynchronous procedure.
4619 Added new SILC_SKE_STATUS_PENDING status to indicate the
4620 request is pending and a callback will be called to finalize
4623 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4624 indicate that remote end did not send its public key (or
4625 certificate), even though we require it. Added check for this
4626 condition in the SKE. This was a security bug, now fixed.
4628 Defined new SilcSKEVerifyCbCompletion callback that is called
4629 when the verification process is completed.
4631 The affected files lib/silcske/silcske_status.h and
4632 lib/silcske/silcske.[ch].
4634 * Changed the verify_public_key client operation to be async
4635 as well. Defined SilcVerifyPublicKey callback that is used to
4636 indicate the success of the public key verification process.
4638 Changed the server and client to use the new async client
4641 * Changed the Irssi SILC client's internal scheduler to be called
4642 twice as many times as it used to be. As a result the client
4643 should be a bit faster now. Affected file is
4644 irssi/src/silc/core/silc-core.c.
4646 * Added support to Irssi SILC client of asynchronous public key
4647 verification and passphrase inquiry. Affected file is
4648 irssi/src/silc/core/silc-core.c.
4650 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4652 * Do not say "You have left channel %s" in client library.
4653 Moved it to the application. Affected files are
4654 lib/silcclient/command.c and silc/client_ops.c.
4656 * Fixed silc_client_get_clients. Command context was not
4657 duplicated and was freed memory in the callback. Affected
4658 file lib/silcclient/idlist.c.
4660 * Do not say "you are now talking..." on JOIN command in the
4661 client library. The appliation must handle it.
4663 * Do not say ".. changed topic to" in command reply in the
4664 client libary. The application must handle it.
4666 * Fixed TOPIC command sending in the client library.
4668 * Fixed a memory leak in silc_client_command_free in the file
4669 lib/silcclient/command.c.
4671 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4673 * Imported a modified version of Irssi client to the source tree.
4674 The Irssi will be used to create a new client called
4675 Irssi SILC. Imported to irssi/.
4677 Added silc_core_init_finish function to the Irssi. Affected
4678 file irssi/configure.in.
4680 A lot changes in the Makefile.ams around the irssi tree.
4682 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4684 * Do not rehash if the new size is same as the old size of the
4685 hash table, in the silc_hash_table_rehash*. The affected file
4686 lib/silcutil/silchashtable.c.
4688 * Replaced hash_table_del_by_context calls from the server
4689 (when channel->user_list and client->channels) to the
4690 hash_table_del as it is sufficient and faster.
4692 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4694 * Added silc_hash_table_list, silc_hash_table_get and the
4695 SilcHashTableList structure to provide an alternative way to
4696 traverse the hash table. The affected files are
4697 lib/silcutil/silchashtable.[ch].
4699 * Changed the server's idlist routines to use the hash table
4700 routines to optimize the code.
4702 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4704 * Replaced the client entry's `channel' list and channel entry's
4705 `user_list' list to hash tables for optimized lookup. Changed
4706 the code to use the hash table interface around the code.
4707 Affected file lib/silcd/idlist.[ch].
4709 * Added `auto_rehash' boolean argument to the function
4710 silc_hash_table_alloc to indicate whether the hash table should
4711 auto-rehash when it thinks is appropriate time. It will
4712 increase the hash table size if the there is twice as much
4713 entries in the table than the size of the table, and will
4714 decrease the size if there are twice as less entries than
4715 the size of the table.
4717 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4719 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4721 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4723 * silc_idcache_purge_by_context deletes the entry now by context
4724 as it is supposed to do. Affected file lib/silccore/idcache.c.
4726 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4727 client is not anymore valid (WHOWAS givens the info) and not
4728 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4730 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4732 * Removed the `data' and `data_len' arguments from the ID Cache
4733 interfaces and added `name' argument. ID Cache does not handle
4734 anymore the binary data only a names associated with given ID.
4736 * When hashing a Client ID with silc_hash_id the entire ID is
4737 not hashed anymore, instead only the hash of the Client ID is
4738 hashed. This way we can access the Client ID from the cache
4739 with Client ID but with the hash of the ID (which is a hash of
4740 the nickname) as well without any difference in performance.
4742 Added also silc_idcache_find_by_id_one_ext to do one on one
4743 searching when we have the actual ID. Added also function
4744 silc_hash_client_id_compare. The affected files are
4745 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4747 * When hashing the name associated with a ID it is always done
4748 in lowercase. This way we can access the cache without worrying
4749 about case-sensitivity, even though, for example nicknames are
4752 * Fixed a bug in server with channel message sending. It put
4753 wrong ID type as destination ID. The affected file
4754 silcd/packet_send.c.
4756 * silc_idcache_del_by_context now deletes from all hash tables
4757 by context. Affected file lib/silccore/idcache.c.
4759 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4761 * Changed the client library to use the new ID Cache interface.
4762 Changes around the source tree.
4764 * Added silc_hash_table_rehash_ext to rehash with specific
4765 hash function. Affected file lib/silcutil/silchashtable.[ch].
4767 * Added silc_hash_string_compare to compare two strings in the
4768 hash table. Affected file lib/silcutil/silcutil.[ch].
4770 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4772 * Added new function silc_idcache_del_by_context into the
4773 lib/silccore/idcache.[ch].
4775 * Changed the server's ID list routines to use the new ID Cache
4776 interface. Changes around the source tree.
4778 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4780 * Added silc_hash_table_del[_by_context]_ext functions in to the
4781 lib/silcutil/silchashtable.[ch].
4783 Removed silc_hash_table_find_all* routines and added new
4784 silc_hash_table_find_foreach to replace them.
4786 Added silc_hash_table_replace_ext function as extended
4787 replacing function. Separated the simple hash table interface
4788 from the extended hash table interface in the file
4789 lib/silcutil/silchashtable.h.
4791 * Fixed minor bugs and changed it to use some of the new
4792 hash table functions in lib/silccore/idcache.c
4794 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4796 * Added new function silc_hash_table_find_all to return all keys
4797 in the hash table by the specified key. As the hash table is
4798 collision resistant it also makes it possible to have several
4799 duplicate keys in the hash table. This function may be used to
4800 find all of the keys from the hash.
4802 Added user_context arguments to the SilcHashFunction,
4803 SilcHashCompare and SilcHashDestructor to deliver user specified
4806 Added new fuctions silc_hash_table_find[_all]_ext to do
4807 extended lookup with specified hash and compare functions and
4808 specified user contexts.
4810 Added new function silc_hash_table_add_ext to add the key
4811 with specified hash function and user context.
4813 Added new function silc_hash_table_foreach to traverse all
4814 entrys in the hash table. Added SilcHashForeach callback
4817 Added new function silc_hash_table_del_by_context to delete
4818 the entry only if the context associated with the key matches.
4820 Affected files are lib/silcutil/silchashtable.[ch].
4822 * Removed silc_hash_[server/client/channel]_id and added just
4823 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4824 silc_hash_id_compare to compare two ID's using as the hash table
4825 comparison function. Added also silc_hash_data to hash
4826 binary data and silc_hash_data_compare to compare it.
4828 * Removed silc_idlist_find_client_by_hash as it is not needed
4829 anymore. Affected file silcd/idlist.[ch].
4831 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4832 to use internally the SilcHashTable. The new ID Cache is a lot
4833 faster than the old one. Some of the ID Cache interface was also
4834 rewritten and obsolete and stupid functions were removed.
4836 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4838 * Added entry_count field to the SilcHashTable to keep the number
4839 of the entries in the table. Implemented the function
4840 silc_hash_table_rehash. Added new function
4841 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4843 Fixed a minor bug in silc_hash_table_free.
4845 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4846 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4847 into the lib/silcutil/silcutil.[ch].
4849 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4851 * Implemented a collision resistant hash table into the
4852 lib/silcutil/silchashtable[ch]. See the header and the source
4853 for the SilcHashTable API.
4855 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4857 * Merged dotconf version 1.0.2 into lib/dotconf.
4859 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4861 * Do not compile anything in lib/silcsim/* if the SIM support
4862 is not enabled. The tree should now compile without problems
4865 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4867 * Compiled the SILC under cygwin. Compiled and tested briefly
4868 without problems. More tests needed. The SIMs didn't compile
4871 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4873 * Fixed possible crash in silc_get_username in the
4874 lib/silcutil/silcutil.c.
4876 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4878 * Fixed a va_arg in silc/client_ops.c.
4880 * Oops, RC5 routines were named AES and caused some problems
4881 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4883 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4885 * Added new SilcIDIP structure into the lib/silccore/id.h and
4886 replaced the old `ip' fields from all SILC ID's to that type.
4887 This is a step towards IPv6 support.
4889 The silc_id_get_len takes now the ID as an extra argument.
4890 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4891 both IPv4 and IPv6 based ID's.
4893 The affected files are lib/silccore/id.[ch] and other files
4894 around the tree using these routines.
4896 * Removed the ID length arguments in server from various
4897 silc_server_send_notify_* routines -> they are not needed
4900 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4902 * Fixed memory leak in silc_encode_pem_file in the file
4903 lib/silcutil/silcutil.c.
4905 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4907 * Check minor version as well in the SKE. Affected files are
4908 silcd/protocol.c and lib/silcclient/protocol.c.
4910 * Added --identifier option to the server so that an identifier
4911 can be when creating the public key for the server. Affected
4912 file is silcd/silcd.c.
4914 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4915 lib/silccrypt/silcpkcs.c.
4917 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4919 * Register default ciphers and stuff when using -C option with
4920 the server. Affected file sildc/silcd.c.
4922 * Put back the servers public key filename format, it is better
4923 than the new one. For now, the client keys are saved with the
4924 new filename format. The affected file silc/client_ops.c.
4926 * Implemented the Cipher API for the rest of the ciphers that
4927 did not implement it or implemented it the wrong way.
4929 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4931 * Register default ciphers and stuff when using the -S option
4932 in the client. Affected file silc/silc.c. Same also when
4933 creating new key pair with -C option.
4935 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4937 * Fixed the silc_verify_public_key client operation function to
4938 save the public keys differently. The fingerprint is now
4939 used as filename and not the hostname. This way also the
4940 client keys are saved uniquely and not with hostnames. The
4941 affected file is silc/client_ops.c.
4943 * Trimmed the silc_hash_fingerprint function to remove extra
4944 whitespaces from the end of the fingerprint. The affected
4945 file is lib/silccrypt/silchash.c.
4949 * Added silc_cipher_register_default function to register all
4950 default ciphers. It can be used when configuration files
4951 does not exist and the application does not want any specific
4952 ciphers in any specific order.
4954 The SilcDList is now used as silc_cipher_list dynamically
4955 allocated cipher list. Removed the static list all together
4956 and now all ciphers must be allocated to the dynamic list.
4957 The silc_cipher_alloc routine was changed to check only the
4960 All silc_cipher_* routines that used to return int returns
4963 The affected files lib/silccrypt/silccrypt.[ch].
4965 * The same thing was done to silc_hash_* as for silc_cipher_*
4966 routines. Affected files lib/silccrypt/silchash.[ch].
4968 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4969 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4970 Added also silc_pkcs_[un]register[_default] functions.
4971 Removed the data_context from the PKCS API.
4973 * Added silc_hmac_register_default function to register default
4974 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4975 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4976 to unregister all hmacs at once.
4978 * Register the default ciphers, hash functions, PKCSs and HMACs
4979 if client's configuration file does not exist. The affected
4982 * The client did not load the hash functions from the SIM
4983 modules at all. Added support for this. Affected file is
4984 silc/clientconfig.c.
4986 * When decoding public key with silc_pkcs_public_key_decode, check
4987 the supported algorithm only if PKCS are registered. Affected
4988 file lib/silccrypt/silcpkcs.c. The same was done with the
4989 silc_pkcs_private_key_decode.
4991 * Fixed the SILC List routines to keep the list always in order.
4992 It used to change the list's order when traversing the list but
4993 not it preserves the order. Affected file lib/trq/silclist.h.
4995 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4997 * Added the client library to use the SilcSocketConnection's
4998 reference counter (by silc_socket_dup) to prevent the bug that
4999 the socket object may be freed underneath async operation.
5001 * The name resolv library checking fixes in the configure.in.pre.
5004 * Created new version of the protocol drafts for future
5005 development. The -03 drafts are the ones that will be changed
5006 in the trunk now and the -02 will remain as they are.
5008 * Send list of CUMODE notifys to the router when announcing
5009 the channel users to the router. Affected file silcd/server.c.
5010 If the router receiving channel founder CUMODE for a channel
5011 that already has channel founder it will send CUMODE notify
5012 to the sender to remove the channel founder rights from the
5013 announced client. Affected file silcd/packet_receive.c.
5015 * The CUMODE notify may now use Server ID as well as the entity
5016 who changes the mode. Updated protocool specs.
5018 * Updated INSTALL and README files.
5020 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5022 * New web pages in the http://silc.pspt.fi. The pages was
5027 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5029 * Implemented the [DenyConnectin] config section in the server.
5030 Added silc_server_config_denied_conn to check whether incoming
5031 connection is denied. Affected file silcd/serverconfig.[ch].
5033 * Do not check the ports when checking the incoming configuration
5034 data if the port is 0, meaning any. Affected file is
5035 silcd/serverconfig.c.
5037 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5039 * Fixed buffer overflow in silc_string_compare in the file
5040 lib/silcutil/silcutil.c.
5042 * Fixed double free in silc_server_command_leave in the file
5045 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5047 * Fixed the version checking in the server. Affected file is
5050 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5052 * Fixed the configuration data fetching when accepting new
5053 connections in the server. Affected file silcd/server.c.
5055 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5057 * Added `sender_entry' argument to the function
5058 silc_server_packet_relay_to_channel so that we can check
5059 whether some destination actually belongs to the same route
5060 the sender belongs (ie, we must not resend the packet to the
5061 sender). Affected file silcd/packet_send.[ch].
5063 * Added `servername' field to the SilcClientEntry in the server
5064 to hold the name of the server where client is from. Affected
5065 file is silcd/idlist.h.
5067 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5069 * Moved the channel message encrypting in the router betwen
5070 router connections from silc_server_channel_message to the
5071 silc_server_packet_relay_to_channel since we want to check
5072 whether we have anybody channel before encrypting anything.
5073 Affected files silcd/packet_[receive/send].c.
5075 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5077 * Fixed the [AdminConnection] server config section to support
5078 multiple entries. Affected file silcd/serverconfig.c.
5080 * Added support into the server to check the validity of the
5081 incoming connection before executing any KE or authentication
5084 * The connection configuration is now saved to the KE and
5085 connection auth protocol contexts and not fetched anymore in
5086 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
5088 * The local hosts listenning address and port is also resolved
5089 now when starting the server. We want to have the socket object
5090 to include the real address and port for the listener. Added
5091 new function silc_net_check_local_by_sock into the files
5092 lib/silcutil/silcnet.[ch].
5094 * Fixed a broadcast bug in server -> do not broadcast if we
5097 * Fixed a routing bug. Do not route broadcast packets ever.
5098 Broadcast packets must be processed always and not routed since
5099 they may be destined to some other host than yourself and thus
5100 would get routed without no good reason. Affected file is
5103 * Added function silc_server_config_is_primary_route to check
5104 whether primary router connection has been configured (a router
5105 configuration that we are initiating). If there is not, we
5106 will assume that there is only two routers in the SILC network
5107 and we will use the incoming router connection as our primary
5108 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
5110 * Changed the order of the broadcasting. Broadcast _after_ the
5111 packet has been processed not before. Affected file is
5114 * Fixed a [ClientConnection] parsing bug. The port was never
5115 parsed correctly thus resulting to port 0. Affected file
5116 silcd/serverconfig.c.
5118 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
5119 argument and did not set the broadcast packet flag. Affected
5120 file silcd/packet_send.c. Fixed same bug in the function
5121 silc_server_send_notify as well.
5123 * If we receive NEW_ID packet for our own ID in the server, ignore
5126 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5130 * Removed the nickname from the Private Message Payload.
5131 Updated the code and the protocol specs.
5133 * Updated protocol specs for submitting to the IETF.
5135 * Tweaked the Random Number Generator a bit. Affected file
5136 lib/silccrypt/silcrng.c. Exported a new function
5137 silc_rng_[global]_add_noise which can be used to add more
5140 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5142 * Do not parse packets with different timeout when protocol
5143 is active -> may cause problem with rekey. Affected file
5146 * When server receives signoff notify it must not create
5147 new channel key if the client is on any channels since the
5148 sender of the signoff notify will create it.
5150 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5152 * Added printing of error messages during SKE protocol from the
5153 failure packet sent by server during SKE. Affected file
5156 * Removed the client's failure_callback handling with timeout
5157 and handle it immediately when received.
5159 * The SKE library returned wrong type in SUCCESS and FAILURE
5160 packets. They must be 32 bit MSB not 16 bit MSB.
5162 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5164 * Ok, rewrote the logic of the re-key and now it seems to work.
5165 I tested it on high traffic with frequent re-keys without
5166 problems. Added hmac_receive (and renamed hmac to hmac_send)
5167 in SilcClientConnection in lib/silcclient/client.h and
5168 in SilcIDListData in silcd/idlist.h. Also, removed the
5169 SilcPacketParserContext's cipher and hmac fields as they are
5170 not needed anymore and actually caused some problems when
5171 the ciphers and hmac's changed underneath the packet parser.
5173 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5175 * If re-key protocol is active then process the incoming packets
5176 synchronously since we must assure that icoming packets encrypted
5177 with the old key is processed before the new keys is set to
5178 use. This is true other packets than for REKEY packets.
5179 Affected file silcd/server.c. The same was done to client library
5180 as well, affected file lib/silcclient/client.c.
5182 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5184 * Fixed bug in client and server to accept the force send if
5185 the packet is send from silc_[server/client]_packet_process
5186 function. Otherwise the packets are never delivered, oops.
5188 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5190 * Disable force sending of packets when REKEY protocol is active.
5191 We must assure that no packet is sent directly when rekey is
5192 performed. All packets must be sent through packet queue.
5193 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
5194 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
5195 function is silc_[server/client]_packet_send_real to check
5198 * Replaced the SIM paths from example config files to
5199 /usr/local/modules. Also, make install creates now
5200 /usr/local/silc/logs directory to hold all the SILC server
5203 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5205 * Made the configure.in.pre work on Solaris. Patch by salo.
5207 * Made all ciphers compatible with non-x86 machines. Defined
5208 CBC mode macros into lib/silccrypt/ciphers_def.h.
5210 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5212 * Fixed the make install.
5214 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5216 * When MAC computation fails the silc_packet_decrypt returned 0
5217 even though it was supposed to return -1. Fixed this. The
5218 affected file is lib/silccore/silcpacket.c.
5220 * Do not replace the config files in /etc/silc (in make install)
5221 if they already exist. Affected file ./Makefile.am.
5223 * Do not send re-key packets immediately but through packet queue.
5224 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
5226 * Changed silc_net_check_host_by_sock to return FALSE if the
5227 IP/DNS could not be resolved. Though, it returns the IP address
5228 now even if it could not resolve it (but returns also FALSE).
5229 Affected file lib/silcutil/silcnet.[ch].
5231 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5233 * Added silc_pkcs_decode_identifier to decode the public key's
5234 identifier. Affected file lib/silccrypt/silpkcs.[ch].
5235 Added also silc_pkcs_free_identifier. Added also new context
5236 SilcPublicKeyIdentifier.
5238 * Added -S option to the silc client. It is used to dump the
5239 contents of the specified public key file.
5241 * Changed the PKCS api to return the public key length when
5242 setting the public key.
5244 * Fixed a fatal bug in the public and private key file loading.
5245 Affected file lib/silccrypt/silcpkcs.c.
5247 * Execute the packet parsing for client with zero (0) timeout
5248 if the protocol is active. Affected file silcd/server.c.
5250 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5252 * Made the key generation options to the silcd program. Added
5253 -C option, equivalent to client's option.
5255 * Added new [ServerKeys] config section to the server. It
5256 configures the server's public and private key.
5258 * Defined generic Public Key Payload into the protocol
5259 specification to send specific type of public keys and
5262 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
5263 public key or certificate.
5265 * Implemented the GETKEY command to the server and to the
5266 client library and on user interface.
5268 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5270 * Made preliminary `make install' work.
5272 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5274 * Added SilcServerRekey context into silcd/idlist.h.
5276 * Added the PFS support as defined in the specification to the
5277 SKE protocol. Affected files lib/silcske/*.c.
5279 * Added `ske_group' field to the SilcServerRekey context to hold
5280 the number of the SKE group that is used with PFS in re-key.
5281 Affected file silcd/idlist.h.
5283 * Added PFS re-key support to the server. Affected file is
5286 * Added silc_protocol_cancel to cancel execution of the next
5287 state of the protocol. Affected file is
5288 lib/silccore/silcprotocol.[ch].
5290 * Added the re-key support with and without PFS to the client
5291 library. Re-key is performed once in an hour, by default.
5293 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
5294 Added silc_client_rekey_callback and silc_client_rekey_final.
5295 Affected files are lib/silcclient/protocol.[ch] and
5296 lib/silcclient/client.[ch].
5298 * Removed the `hmac_key' and `hmac_key_len' fields from the
5299 SilcClientConnection structure; not needed. Affected file is
5300 lib/silcclient/client.h.
5304 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5306 * Do not ask whether user wants to use the negotiated private key
5307 for private messages, just use it. Affected file is
5308 silc/local_command.c.
5310 * Added `send_enc_key' and `enc_key_len' fields to the
5311 SilcIDListData structure since they are needed in the re-key
5312 phase. Affected file is silcd/idlist.[ch].
5314 * Implemented the simple re-key protocol into the server.
5315 Affected files silcd/server.c and silcd/protocol.[ch]. The
5316 re-key will be performed once in an hour, by default.
5318 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
5319 Added silc_server_rekey, silc_server_rekey_callback and
5320 silc_server_rekey_final.
5322 * Removed Tunneled flag from the protocol. Updated the code
5323 and the specifications.
5325 * Adde `pfs' field to the SilcIDListData to indicate whether
5326 the PFS is to be performed in the re-key. Affected file is
5329 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5331 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
5332 int64 of at least the xintXX size. If void * is less that 4
5333 bytes uint32 * will be used. Defined bool as boolean.
5335 * Changed _ALL_ unsigned long and unsigned int to uint32,
5336 unsgined short to uint16 in the source tree.
5338 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
5339 not handle clients that has entry->data.registered == FALSE.
5340 They are not in the network anymore. Affected file is
5343 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5345 * Implemented the sending of the SERVER_SIGNOFF notify in the
5346 server. Affected file is silcd/server.c.
5348 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
5349 Added also silc_notify_payload_encode_args into the
5350 lib/silccore/silcnotify.[ch].
5352 * Implemented ther SERVER_SIGNOFF notify handling in the server.
5353 Affected file silcd/packet_receive.c.
5355 * Implemented the SERVER_SIGNOFF notify handling in the client
5356 library. Affected file lib/silcclient/client_notify.c. Also,
5357 implemnted the printing of the SERVER_SIGNOFF info to the
5358 application. Affected file silc/client_ops.c.
5360 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
5361 if the deleting was successful. Affected file silcd/idlist.[ch].
5363 * Added support for public key authentication in the connection
5364 authentication protocol in the client library. Affected file
5365 lib/silcclient/protocol.c.
5367 * Changed the server's silc_idlist_get_clients_by_* interface
5368 to support already allocated array so that new entries may be
5369 added to pre-allocated array. Affected file silcd/idlist.[ch].
5370 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
5371 and command replies.
5373 * All command reply functions in the server now calls the
5374 pending command callback even if error occured. This way the
5375 error will be delivered to the client as well. Affected files
5376 silcd/command.c and silcd/command_reply.c.
5378 * Fixed INFO command to return local server's info if no server
5379 was provided. Affected file lib/silcclient/command.c.
5381 * Removed RESTART command for good. Updated the code and the
5384 * Rewrote parts of the task system. It is a bit simpler now.
5385 Removed unsued task priorities. The affected files are
5386 lib/silcutil/silctask.[ch].
5388 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5390 * Moved the USERS printing from the library to the application.
5391 Affected files lib/silcclient/command.c and silc/client_ops.c.
5393 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5397 * Added channel key re-key support. The re-key is perfomed
5398 only by the router and is done once in an hour. Added `rekey'
5399 field to the SilcChannelEntry in the server. Affected files
5400 silcd/server.c and silcd/idlist.h.
5402 * Added silc_task_unregister_by_context into the file
5403 lib/silcutil/silctask.[ch].
5405 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5407 * Added SILC_UMODE_GONE mode to indicate when the client is not
5408 present in the SILC network. Added also support to the local
5409 command AWAY that will set this mode. Added support of showing
5410 "xxx is gone" in WHOIS command. The USERS command shows the
5411 gone status as well.
5413 * Fixed setting server and router operator privileges in the
5414 server's UMODE command. Affected file silcd/command.c.
5416 * Merged the SKE KE1 and KE2 payloads into one payload. The
5417 new KE payload is equivalent to the old KE2 payload.
5419 Cleaned up the SKE Start Payload parsing. It now uses the
5420 simple buffer unformatting to do the parsing. A lot faster
5423 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
5424 to the SKE that is used to indicate whether both of the SKE
5425 parties should perform authentication. By default only the
5426 responder performs authentication. By setting this flag also
5427 the initiator must do authentication. By default it is unset
5428 since in normal SKE case, client to server connection, only
5429 the responder should do authentication. When doing SKE between
5430 two clients both should perform authentication. Updated the
5431 code and the protocol specs.
5433 * A little fix to IDENTIFY command in the server. Search the
5434 client first by hash not nickname. Affected file is
5437 * Fixed the silc_client_close_connection to support closing
5438 the client to client connections wihtout deleting too much
5439 data. Affected file lib/silcclient/client.c.
5441 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
5442 are received if protocol used to be active but is not anymore
5443 the application would crash due to NULL pointer dereference.
5444 Affected files silcd/server.c and lib/silcclient/client.c.
5446 * Added `hash' field to the SilcClientConnection to include
5447 the hash function negotiated in the SKE protocol.
5449 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
5450 to set the channel founder authentication data. A client can
5451 claim the founder rights later by providing the authentication
5452 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
5453 This way the channel founder can regain the channel founder
5454 privileges even it is left the channel. This works only on
5455 local server and the client must be connected to the same
5456 server to be able to regain the founder rights. Updated the
5457 protocol specs accordingly.
5459 Added support to the CMODE command in the client to set the
5460 founder auth data. Read the README to see how to set it.
5462 Added support to the CUMODE command to claim the founder
5463 rights. Read the README to see how to do it.
5465 Added support for the founder authentication to the Channel
5466 Entry in the server. Affected file silcd/idlist.h.
5468 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
5469 server's CMODE command. Affected file silcd/command.c.
5471 * Added the following new functions into lib/silccore/silcauth.[ch]:
5472 silc_auth_get_method and silc_auth_get_data.
5474 * The server now saves the remote hosts public key to the
5475 SilcIDListData pointer. Affected file silcd/protocol.c.
5477 * The normal server now does not remove the channel entry from
5478 the cache if the founder authentication data is set. It used
5479 to remove it if the founder was the last one on the channel on
5480 the server and left the channel. The auth data is saved and
5481 if the channel is re-joined later the old entry is used with
5482 the old auth data. Affected files silcd/command_reply.c and
5485 * Removed the `pkcs' field from the SilcIDListData structure
5486 in the server; it is not used. Affected file silcd/idlist.h.
5488 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5490 * Fixed packet processing on slow links. Partial packets were
5491 never re-processed because the incoming data buffer was cleared
5492 by the application. Application must not directly clear the
5493 sock->inbuf, the packet processing routines handle it. Fixed
5494 this in client library and in server.
5496 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5498 * Fixed the WHOIS and IDENTIFY send reply function to really
5499 check whether to send list or just one entry. Affected file
5502 * Cleaned up the LEAVE command's channel key distribution. The
5503 affected file silcd/command.c.
5505 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
5506 can enforce the channel mode as well. In that case the ID
5507 includes the ID of the server. The code now enforces the
5508 mode change if the router have different mode than the server.
5510 * The notify client operation with CMODE_CHANGE notify can now
5511 return NULL client_entry pointer if the CMODE was not changed
5512 by client. Application must check for this.
5514 * Added <Server ID> argument to INFO command to support server
5515 info fetching by Server ID.
5517 * Added silc_server_announce_get_channel_users to get assembled
5518 packets of channel users of the specified channel. Affected
5519 file silcd/server.[ch].
5521 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
5522 was freed underneath the ID Cache.
5524 * Re-announce clients when the server received CHANNEL_CHANGE
5525 notify from the router. Affected file silcd/packet_send.c.
5527 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5529 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
5530 crashed since it did not handle the fact that there is no cipher
5531 called "3" and didn't check the error condition. Now fixed.
5533 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
5534 flag. It can be used to send message requests.
5536 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5538 * Implemented the RESTART command in the client.
5540 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
5541 notice type messages. Added notice printing to the user
5544 * The channel keys are not re-generated if the channel's mode
5545 is PRIVKEY, ie private key on the channel exists. Affected
5546 files silcd/server.c and silcd/command.c.
5548 * Fixed a little bug in channel message delivery when channel
5549 private keys are set in the server. Affected file is
5550 silcd/packet_send.c.
5552 * Changed the setting on channel->on_channel = TRUE from the
5553 silc_client_save_channel_key to the JOIN command reply. The
5554 key payload is not received if the private channel key is set.
5555 Affected file lib/silcclient/command_reply.c and the
5556 lib/silcclient/client_channel.c.
5558 * When the CMODE_CHANGE notify is sent and the channel private
5559 key mode is removed the channel key must be re-generated in
5560 other cells as well. Added this support for the router in the
5561 silcd/packet_receive.c.
5563 * Added new local command NOTICE to send notice message on
5564 channel. Affected file silc/local_command.[ch].
5566 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5568 * Added new local command ME to the client. It is used to send
5569 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
5570 some action. Affected file silc/local_command.[ch].
5572 * Changed channel_message and private_message client operations
5573 to deliver the message flags to the application. Added also
5574 the `flags' arguments to the silc_client_send_channel_message
5575 and silc_client_send_private_message functions. Affected file
5578 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5580 * Redefined the Private Message Payload to support private message
5581 keys and to support the new private message flags. Updated
5582 the protocol specs. Flags makes it possible to have for example
5583 CTCP style messages.
5585 * Added new type SilcPrivateMessagePayload and defined an API
5586 for it in the lib/silcclient/silcprivate.[ch].
5588 * Tested private message private keys successfully. Tested the
5589 private message key set, unset and list commands with the new
5592 * Redefined the Channel Message Payload to include the channel
5593 message flags (equal with private message flags) to support
5594 for example CTCP style messages.
5596 * Defined some of the message (for channel and private message)
5597 flags. Updated the protocol specs and added the flags to the
5598 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5600 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5602 * Added SilcKeyAgreementStatus type to the key agreement routines
5603 to indicate the current status and error if one occured.
5604 The status types are defined in the lib/silcclient/silcapi.h.
5606 * Added new local command KEY that is used to set and unset private
5607 keys for channels, set and unset private keys for private messages
5608 with remote clients and to send key agreement requests and
5609 negotiate the key agreement protocol with remote client. The
5610 key agreement is supported only to negotiate private message keys,
5611 it currently cannot be used to negotiate private keys for channels,
5612 as it is not convenient for that purpose.
5614 * Fixed a minor pending callback setting bug in the function
5615 silc_client_get_client_by_id_resolve, now the function works.
5616 Affected file lib/silcclient/idlist.c.
5618 * Added function silc_net_get_local_port to get local bound
5619 port by socket. Added to lib/silcutil/silcnet.[ch].
5621 * Added `sockets' and `sockets_count' fields to the SilcClient
5622 object. They hold the sockets of the listenning sockets in
5623 the client. Listenning sockets may be for example the key
5624 agreement server. Affected file lib/silcclient/client.[ch].
5625 Added functions the silc_client_add_socket and the
5626 silc_client_del_socket. They are exported to the application
5629 * Added ~./silc/clientkeys to support other client's public keys.
5631 * Renamed verify_server_key client operation to verify_public_key
5632 and added one argument to indicate the type of the connection
5633 (server, client etc.).
5635 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5637 * Added silc_server_connection_auth_request to handle the
5638 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5639 silcd/packet_receive.[ch].
5641 * Added silc_server_send_connection_auth_request into the
5642 silcd/packet_send.c to send the connection auth request packet.
5644 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5647 * Fixed the public key authentication in responder side in the
5648 server. The `auth_data' pointer includes the SilcPublicKey
5649 not the path to the public key. Affected file silcd/protocol.c.
5651 * Implemented the public key authentication in the initiator side
5652 in the server. Affected file silcd/protocol.c.
5654 * Removed the [RedirectClient] config section from the server
5655 configuration. Is not needed and I don't want to implement it.
5657 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5659 * Cleaned up the CMODE command in the server. It now works
5660 correctly and supports all the modes defined in the protocol.
5661 Affected file is silcd/command.c.
5663 * Added `hmac_name' field to the SilcChannelEntry in the server
5664 to hold the default HMAC of the channel. It can be set when
5665 creating the channel (with JOIN command). Affected files
5668 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5669 type to indicate the change of the current cipher and hmac
5670 on the channel. Client can safely ignore the <cipher> argument
5671 (if it chooses to do so) since the CHANNEL_KEY packet will
5672 force the channel key change anyway. The <hmac> argument is
5673 important since the client is responsible of setting the new
5674 HMAC and the hmac key into use.
5676 * Fixed the CMODE command in the client library as well.
5678 * Tested CMODE command in router environment successfully.
5680 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5682 * Show the version of the remote client (or server) when connecting
5683 to the server. It is logged to the log file. Affected file
5684 is silcd/protocol.c.
5686 * Fixed the KILLED notify handling in the client library. The
5687 client must be removed from all channels when receiving the
5690 Also, do not remove the client entry when giving the KILL
5691 command but when the KILLED notify is received.
5693 * Removed silc_idlist_find_client_by_nickname from the server.
5694 Not needed anymore. Affected files silcd/idlist.[ch].
5696 * Implemented the CHANNEL_CHANGE notify type handling to the
5697 server. Affected file silcd/server.c.
5701 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5703 * Added silc_server_send_notify_invite to send the INVITE
5704 notify between routers.
5706 * Implemented the INVITE command correctly to the server.
5708 * Implemented the INVITE notify type handling in the server.
5710 * Implemented the INVITE command to the client library and on the
5713 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5715 * Added function silc_server_get_client_resolve to find the
5716 client entry by ID from all ID lists and then resolve it
5717 (using WHOIS) if it cannot be found. Affected file is
5720 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5722 * Implemented the BAN command to the client library.
5724 * The JOIN command in the server now checks the invite list
5727 * Changed the silc_command_reply_payload_encode_va and the
5728 silc_command_payload_encode_va to support that if argument is
5729 NULL it ignores and checks the next argument. Affected file
5730 lib/silccore/silccommand.c.
5732 * Added silc_server_send_notify_ban to send the BAN notify
5733 type between routers.
5735 * Chaned the silc_notify_payload_encode to support that if
5736 argument is NULL it ignores and checks the next argument.
5737 Affected file lib/silccore/silcnotify.c.
5739 * Tested ban lists in router environment successfully.
5741 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5743 * Implemented BAN command to the server, in silcd/command.[ch].
5745 * Removed the BAN and INVITE_LIST modes from the CMODE command
5748 * Added function silc_string_match to regex match two strings.
5749 Affected files lib/silcutil/silcutil.[ch].
5751 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5753 * Redefined parts of the SilcChannelEntry in the server to support
5754 the new ban and invite lists.
5756 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5758 * Redefined the INVITE command. The same command can be used to
5759 invite individuals to the channel but also to manage the invite
5760 list of the channel (to add to and remove from the invite list).
5761 Updated the protocol specs.
5763 * Added new command SILC_COMMAND_BAN that can be used to manage
5764 the ban list of the channel. Updated the protocol specs.
5766 * Removed the channel modes: the SILC_CMODE_BAN and the
5767 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5768 in the CMODE command. The equivalent features are now available
5769 using INVITE and BAN commands. Updated the protocol specs.
5771 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5772 in the network about change in the current ban list. The notify
5773 type is not used by the client.
5775 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5776 support the invite lists.
5778 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5780 * Added new function silc_string_regexify that converts string
5781 including wildcard characters into regex string that can
5782 be used by the GNU regex library. Added into the file
5783 lib/silcutil/silcutil.[ch].
5785 Added silc_string_regex_combine to combine to regex strings
5786 into one so that they can be used as one regex string by
5787 the GNU regex library. Added into the file
5788 lib/silcutil/silcutil.[ch].
5790 Added silc_string_regex_match to match two strings. It returns
5791 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5793 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5795 * Imported GNU regex to the soruce tree into lib/contrib.
5796 Fixed some compiler warning from the regex.c.
5798 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5800 * Fixed MOTD command in the server to work in router environment.
5802 * Fixed the MOTD command in the client library to support
5803 the server argument in the command.
5805 * Added `nickname_len' argument to the silc_idlist_add_client
5806 in the server, as the `nickname' argument may be binary data
5809 * Added silc_idlist_get_channels to return all channels from
5812 * Implemented LIST command to the server. Affected file is
5815 * Implemented the LIST command to the client library and on the
5818 * Added [<user count>] argument to the LIST command reply.
5819 With private channels the user count is not shown.
5821 * Updated TODO and README.
5823 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5825 * The client entry's data.registered must be TRUE even with
5826 global client entry on global client list. The data.registered
5827 is used to check whether the client is anymore in the network,
5828 for example with WHOWAS command so it must be valid.
5830 * Fixed the WHOWAS command in the server. It now actually works
5831 in router environment. Added function into silcd/command_reply.c
5832 silc_server_command_reply_whowas_save.
5834 * Added silc_idlist_purge function to the silcd/idlist.c
5835 to periodically purge the ID Cache.
5837 * Fixed INFO command in the server. It works now in router
5838 environment. Added <server name> argument to the INFO command
5839 reply. Updated the protocol specs.
5841 * Fixed minor bug in silc_idcache_purge to not purge if the
5842 expire value is zero.
5844 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5845 they were buggy because of the WHOWAS information.
5847 * Fixed local command MSG to handle the async resolving of
5848 the remote client properly. It used to fail the first MSG.
5849 Affected file silc/local_command.c.
5851 * Added `data_len' field to SilcIDCache context.
5853 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5855 * Update TODO. Todo in commands in the server.
5857 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5859 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5860 used by routers as broadcast packet to inform other routers
5861 about the changed user mode.
5863 Implemented the notify handling in the server. Affected file is
5864 silcd/packet_receive.c. Added the function
5865 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5867 * Added new generic Channel Payload and deprecated the New Channel
5868 Payload. The New Channel Payload is now the generic Channel
5871 * Added new argument `mode' to the silc_server_send_new_channel
5872 as it is required in the Channel Payload now.
5874 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5875 and created a new and real SilChannelPayload to represent the
5876 new generic Channel Payload. Implemented the encode/decode
5877 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5879 * Added silc_server_get_client_channel_list to return the list
5880 of channels the client has joined for WHOIS command reply.
5881 Affected file silcd/server.[ch].
5883 * Implemented the channel list sending in the WHOIS command reply
5884 in server and in the client.
5886 Implemented the channel list displaying on the user interface
5887 as well. Affected file silc/client_ops.c.
5889 * Added silc_channel_payload_parse_list to parse list of Channel
5890 Payloads. It returns SilcDList list of SilcChannelPayloads.
5891 Client for example can use this function to parse the list of
5892 channels it receives in the WHOIS command reply. The caller
5893 must free the list by calling silc_channel_payload_list_free.
5894 Affected files lib/silccore/silcchannel.[ch].
5896 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5898 * Added one new argument <user mode> to the WHOIS command reply
5899 to return the mode of the user in SILC. Updated the protocol
5902 Implemented it to the server and client.
5904 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5906 * Fixed the mode printing on the user interface on joining.
5907 Affected file silc/client_ops.c.
5909 * Implemented the UMODE command and user modes in general to the
5910 client library and to the user interface.
5912 * Implemented the UMODE command to the server.
5914 * The server now sends UNKNOWN_COMMAND error status if client sends
5915 unknown command. Affected file silcd/command.c.
5917 * All server commands now handle the command identifier the right
5918 way when sending the command reply to the client. The client can
5919 use to identify the command replies with the identifier.
5921 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5923 * Added silc_server_get_client_route to resolve the route to
5924 the client indicated by the client ID. Affected file is
5927 * Added silc_server_relay_packet as general function to relay
5928 packet to arbitrary destination. This deprecates functions
5929 like _send_private_message_key, _relay_notify etc. Affected
5930 file is silcd/packet_send.[ch].
5932 Removed silc_server_send_key_agreement,
5933 silc_server_send_private_message_key and
5934 silc_server_packet_relay_notify functions from the file
5935 silcd/packet_send.[ch].
5939 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5940 server. Affected file silcd/packet_receive.[ch].
5942 * Implemented the KILL command to the client. Implemented the
5943 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5944 Affected files lib/silcclient/command[_reply].c and
5945 lib/silcclient/client_notify.c. Implemented the KILL notify
5946 printing in the user inteface.
5948 * Fixed a lot silc_parse_nick memory leaks from the client
5949 library in the file lib/silcclient/command.c.
5951 * Changed the silc_server_send_notify_on_channels's `sender'
5952 argument from SilcSocketConnection to SilcClientEntry to
5953 check the sender as entry and not as connection object and not
5954 to send to the client provided as argument. The affected file
5955 is silcd/packet_send.[ch].
5957 * The notify packets that are destined directly to the client used
5958 to not to be processed by the server. Now changed that and the
5959 server processes all notify packets. After relaying the packet
5960 to the client the notify packet is processed in the server.
5962 * The silc_server_free_client_data now checks whether there is
5963 pending outgoing traffic for the client and purges the data to
5964 the network before removing the client entry.
5966 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5968 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5969 an client is killed from the SILC Network. Updated the protocol
5972 Added new function silc_server_send_notify_killed to the
5973 silcd/packet_send.[ch].
5975 * Added function silc_server_packet_relay_notify to relay notify
5976 packets that are destined directly to a client. In this case
5977 the server does not process the notify packets but merely relays
5978 it to the client. Affected file silcd/packet_send.[ch].
5980 Added also silc_server_packet_process_relay_notify to check
5981 whereto relay the notify. Affected file is
5982 silcd/packet_receive.[ch].
5984 * Implemented the KILL command to the server.
5988 * Added the backup schema desgined last fall to the protocol
5989 specs for everyone to see. The specification is in the
5990 *-spec-xx.txt draft and the packet type definitions for the
5991 backup routers is in *-pp-xx.txt draft. Thusly, added also
5992 new packet type SILC_PACKET_CELL_ROUTERS.
5994 * A big security problem in the implementation discovered. The
5995 signoff of an client did not cause new channel key generation
5996 which it of course should've done. The channel keys must be
5997 always re-generated when client leaves (or signoffs) the channel.
5998 The silc_server_remove_from_channels funtion now handles
5999 the channel key re-generation.
6001 * Added `sender' argument to the silc_server_send_notify_on_channels
6002 to not to send the client provided as argument. Affected file
6003 silcd/packet_send.[ch].
6005 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6007 * Implemented OPER and SILCOPER commands into the server and
6010 * Added silc_auth_verify and silc_auth_verify_data to verify
6011 the authentication directly from the authentication payload.
6012 It supports verifying both passphrase and public key based
6013 authentication. Affected file lib/silccore/silcauth.[ch].
6015 * Added `hash' field to the SilcIDListData structure. It is the
6016 hash negotiated in the SKE protocol. Affected file is
6019 * Slight redesigning of the SilcAuthPayload handling routines.
6020 Do not send SilcPKCS but SilcPublicKey as argument.
6022 * Implemented the public key authentication support to the
6023 serverconfig. The public key is loaded from the provided path
6024 and saved as authentication data to void * pointer. Thus,
6025 changed the unsigned char *auth_data to void *auth_data;
6027 * Fixed SHUTDOWN command to send the reply before the server
6028 is shutdown. :) Affected file silcd/command.c.
6030 * Fixed fatal bug in CONNECT command. The hostname was invalid
6031 memory and server crashed. Affected file silcd/command.c.
6033 * Fixed fatal bug in CLOSE command. The server_entry became
6034 invalid but was referenced later in the command. Affected file
6037 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6039 * Fixed fatal bug in failure packet handling. Server ignored
6040 the failure and thus crashed when it came.
6044 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6046 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
6047 that the command may be executed only once in (about) 2 seconds.
6048 The old SILC_CF_LAG flag is same but allows command bursts up
6049 to five before limiting.
6051 Added the support for CF_LAG and CF_LAG_STRICT flags to the
6052 server code. Various commands now includes the CF_LAG_STRICT
6053 flag to disallow any kind of miss-use of the command.
6055 * Fixed the silc_buffer_unformat to not to allocate any data
6056 if the length of the data is zero. It used to allocate the
6057 length + 1. Affected file lib/silcutil/silcbuffmt.c.
6059 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6061 * Changed the format of AdminConnection configuration section
6062 in the server. Added username of the admin to the format.
6063 Affected files silcd/serverconfig.[ch].
6065 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
6066 to return admin configuration data by host, username and/or
6069 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6071 * Implemented WHOWAS command to the server. Added the functions:
6073 silc_server_command_whowas_parse,
6074 silc_server_command_whowas_send_reply,
6075 silc_server_command_whowas_from_client and
6076 silc_server_command_whowas_from_server
6078 * Added <Client ID> argument to the WHOWAS command reply. Updated
6079 the protocol specs accordingly.
6081 * Implemented WHOWAS command and command_reply to the client
6084 Implemented the WHOWAS printing on the user interface.
6086 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6088 * Added new argument to the WHOWAS command reply, the real name.
6089 It is an optional argument. Updated the protocol specs.
6091 * Added SilcIDCacheDestructor callback that is registered when
6092 the SilcIDCache is allocated. The callback is called when
6093 an cache entry in the ID Cache expires, or is purged from the
6094 cache. Added into lib/silccore/idcache.[ch].
6096 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
6097 to destruct the client entries when the cache entry expires.
6098 Other ID Cache's in server and in the client library ignores
6101 * If the ID Cache entry's `expire' field is zero then the entry
6102 never expires. Added boolean `expire' argument to the
6103 silc_idcache_add function in the lib/silccore/idcache.[ch].
6104 If it is TRUE the default expiry value is used.
6106 * Added silc_server_free_client_data_timeout that is registered
6107 when client disconnects. By default for 5 minutes we preserve
6108 the client entry for history - for WHOWAS command.
6110 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6112 * Added support to the server to enforce that commands are not
6113 executed more than once in 2 seconds. If server receives
6114 commands from client more frequently, timeout is registered
6115 to process the commands. Affected file silcd/command.c.
6116 Added new function silc_server_command_process_timeout.
6118 * Changed NICK_NOTIFY handling in client library to check that
6119 if the client's nickname was changed, so there is no need to
6120 resolve anything from the server.
6122 * Removed error printing from the WHOIS and IDENTIFY commands.
6123 If error occurs then it is ignored silently in the client library.
6124 The application, however, may map the received error to
6125 human readable error string. The application currently maps
6126 the NO_SUCH_NICKNAME error to string.
6128 * Made the command status message public to the application. Moved
6129 them from lib/silcclient/command_reply.c to
6130 lib/silcclient/command_reply.h. The application can map the
6131 received command status to the string with the
6132 silc_client_command_status_message function.
6134 * Added check to the server to check that client's ID is same
6135 as the Source ID in the packet the client sent. They must
6138 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6140 * Added dist-bzip hook to the Makefile.am to make bzip2
6141 compressed distributions.
6143 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6145 * Server now enforces the maximum length for the nickname and
6146 the channel as protocol specification dictates. 128 bytes for
6147 nickname and 256 bytes for channel name.
6149 * Moved the WHOIS printing to the application. The client libary
6150 does not print out the WHOIS information anymore, the application
6151 must do it. Renamed silc_client_command_reply_whois_print to
6152 the silc_client_command_reply_whois_save.
6154 The client's idle time is also sent to the application now, and
6155 the idle is shown on screen.
6157 * Added silc_client_command_reply_identify_save to save the
6158 received IDENTIFY entries.
6160 * Do not check for channel private keys in message sending and
6161 reception if the channel does not have the PRIVKEY mode set.
6162 Affected file lib/silclient/client_channel.c.
6164 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6166 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
6167 just surfaced after chaning the JOIN procedure.
6169 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6171 * Added silc_client_get_clients_by_list to get client entries
6172 from Client ID list, that is returned for example by JOIN
6173 and USERS command replies. The application should use this
6174 function for example when JOIN command reply is received to
6175 resolve the clients already on the channel (library does not
6176 do that anymore as USERS command reply is not used in the JOIN
6177 procedure anymore). Affected files lib/silcclient/silcapi.h and
6178 lib/silcclient/idlist.c.
6180 * JOIN command reply and USERS command reply returns now SilcBuffer
6181 pointers instead of unsigned char pointers when returning
6182 the client list and mode list.
6184 * Added <Client ID> argument to the JOIN command reply, mainly
6185 for the server to identify for which client the command was
6186 originally sent. Updated protocol specs accordingly.
6188 * Added SilcDlist private_key pointer to the SilcChannelEntry
6189 in the client to support the channel private keys. Affected
6190 file is lib/silcclient/idlist.h.
6192 * Added SilcChannelPrivateKey argument to the function
6193 silc_client_send_channel_message so that application can choose
6194 to use specific private ke if it wants to. If it is not provided,
6195 the normal channel key is used, unless private keys are set.
6196 In this case the first (key that was added first) is used
6197 as the encryption key.
6199 * Implemented the support for channel private key handling.
6200 Implemented the following functions:
6202 silc_client_add_channel_private_key,
6203 silc_client_del_channel_private_keys,
6204 silc_client_del_channel_private_key,
6205 silc_client_list_channel_private_keys and
6206 silc_client_free_channel_private_keys
6208 Affected file lib/silcclient/client_channel.c.
6210 * Added the support for the private keys in the channel message
6211 sending and encryption and in the message reception and
6212 decryption. Affected funtions are
6213 silc_client_send_channel_message and silc_client_channel_message.
6215 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6217 * Added SKE's key verify callback to the client library's
6218 KE protocol context. Affected files lib/silcclient/protocol.[ch].
6220 * Removed the statement that server (or router) must send USERS
6221 command reply when joining to the channel so that the client
6222 knows who are on the channel. Instead, the client list and
6223 client's mode list is now sent in the JOIN command reply to the
6224 client who joined channel. This is better solution.
6226 * Added function silc_server_get_users_on_channel and function
6227 silc_server_save_users_on_channel to the silcd/server.[ch].
6229 * Removed function silc_server_command_send_users from the
6232 * Do not show topic on the client library anymore. The topic is
6233 sent in the command reply notify to the application and the
6234 application must show the topic now.
6236 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6238 * Added client searching by nickname hash into the IDENTIFY and
6239 WHOIS commands in the server as they were clearly missing from
6240 them. Affected file is silcd/command.c.
6242 * Fixed a bug in private message receiving in the client library.
6243 The remote ID was freed and it wasn't supposed, now it is
6246 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6248 * Minor fix to the channel payload; allocate the data area, as it
6249 needs to be of specific length.
6251 * If the key agreement port is zero then the operating
6252 system will define the bound port. Affected files are
6253 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
6255 * Added new function silc_channel_payload_decrypt into the file
6256 lib/silccore/silcchannel.[ch].
6258 * Moved the channel message etc, check from silc_packet_decrypt
6259 to applications. The library calls now a generic
6260 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
6261 when the packet is either normal or special. This was done to
6262 allow more wide range of checking that was not allowed when
6263 the code was in library. Now applications can do virtually any
6264 checks to the packet and return to the library the decision how
6265 the packet should be processed. Affected files are
6266 lib/silccore/silcpacket.[ch].
6268 Added silc_server_packet_decrypt_check to the server and
6269 silc_client_packet_decrypt_check to the client library.
6271 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
6272 to send with specified source and destination information.
6274 * Channel message delivery between routers was broken after the
6275 channel key distribution was fixed earlier. The channel key
6276 was used be to distributed to other routers as well which is not
6277 allowed by the protocol. Now this is fixed and channel keys
6278 really are cell specific and the channel message delivery between
6279 routers comply with the protocol specification.
6281 * Fixed various commands in server to check also the global list
6282 for the channel entry and not just the local list. The affected
6283 file silcd/command.c.
6285 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6287 * Added assert()s to buffer formatting and unformatting routines
6288 to assert (if --enable-debug) when error occurs. Affected
6289 file: lib/silcutil/silcbuffmt.c.
6291 * Changed to auto-reconnect to check whether the remote host is
6292 router and register the re-connect timeout if it is. It used
6293 to check that whether we are normal server, but router must do
6294 auto-reconnect with another router as well. Affected file
6297 * Removed the [<key len>] option from CMODE command as the cipher
6298 name decides the key length, nowadays. See the defined ciphers
6299 from the protocol specification.
6301 * Added [<hmac>] option to the CMODE command to define the HMAC
6302 for the channel. Added SILC_CMODE_HMAC channel mode.
6304 * Added [<hmac>] option for the JOIN command so that user can
6305 select which HMAC is used to compute the MACs of the channel
6308 * Added Hmac field to the Channel Message Payload. The integrity
6309 of plaintext channel messages are now protected by computing
6310 MAC of the message and attaching the MAC to the payload. The
6311 MAC is encrypted. Now, it is clear that this causes some
6312 overhead to the size of the packet but rationale for this is that
6313 now the receiver can verify whether the channel message decrypted
6314 correctly and also when private keys are set for the channel the
6315 receiver can decrypt the packet with several keys and check from
6316 the MAC which key decrypted the message correctly.
6318 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
6319 lib/silccrypt/silccipher.[ch].
6321 * Added silc_hash_len to return the digest length into the
6322 lib/silcrypt/silchash.[ch].
6324 * Rewrote parts of Silc Channel Payload interface in the
6325 lib/silccore/silcchannel.[ch]. The encode function now also
6326 encrypts the packet and parse function decrypts it.
6328 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6330 * Fixed a minor formatting bug in the SKE's key material processing.
6331 It actually might have processed the keys wrong way resulting
6334 * Redefined the mandatory HMAC algorithms and added new algorithms.
6335 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
6336 and hmac-md5 truncated to 96 bits. The mandatory is now
6337 hmac-sha1-96. Rest are optional (including the one that used
6338 to be mandatory). Rationale for this is that the truncated HMAC
6339 length is sufficient from security point of view and can actually
6340 make the attack against the HMAC harder. Also, the truncated
6341 HMAC causes less overhead to the packets. See the RFC2104 for
6344 * Added new [hmac] configuration section. The SKE used to use
6345 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
6346 is of course wrong. The official names that must be proposed in
6347 the SKE are the ones defined in the protocol specification
6348 (hmac-sha1-96 for example). The user can configure any hmac
6349 using any hash function configured in the [hash] section. At
6350 least, the mandatory must be configured.
6352 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
6354 * Added HMAC list to the SKE proposal list. It has now both
6355 hash algorithm list and HMAC list. This makes the protocol
6356 incompatible with previous versions. The SKE now seems to work
6357 the way it is supposed to work, for the first time actually.
6359 * Defined plain Hash algorithms to the protocol specification.
6362 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6364 * Implemented support for key agreement packets into the server.
6365 Added functions silc_server_key_agreement and
6366 silc_server_send_key_agreement. Other than these functions,
6367 server has nothing to do with this packet.
6369 * Added support for private message key packets into the server.
6370 Added functions silc_server_private_message_key and
6371 silc_server_send_private_message_key.
6375 * Changed the silc_[client|server]_protocol_ke_set_keys to be
6376 called in the protocol's final callback instead in the END
6377 protocol state. This makes a little more sense and in the same
6378 time in client we can use the same protocol routines for normal
6379 key exchange and to key agreement packet handling as well.
6381 * Added to both client's and server's KE protocol context the
6382 SilcSKEKeyMaterial pointer to save the key material. We will
6383 bring the key material to the protocol's final callback by doing
6384 this. The final callback must free the key material.
6386 * Added SKE's packet_send callback into client's KE protocol
6387 context so that the caller can choose what packet sending function
6388 is used. This way we can use different packet sending when
6389 doing normal SKE when doing key agreement packet handling (in
6390 the key agreement packet handling we do not want to encrypt
6393 * Implemented the responder side of the key agreement routines
6394 in the client. The client can now bind to specified port and
6395 accept incoming key negotiation. The key material is passed
6396 to the application after the protocol is over.
6398 * Implemented the processing of incoming Key Agreement packet
6399 in the client. Added function silc_client_key_agreement to
6402 * Implemented the intiator side of the key agreement routines
6403 in the client. The client can now initiate key agreement with
6404 another remote client. The key material is passed to the
6405 application after the protocol is over.
6407 * Created client_keyagr.c to include all the key agreement
6410 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
6411 SILC_TASK_CALLBACK except that it is not static.
6413 * Created client_notify.c and moved the Notify packet handling
6414 from the client.[ch] into that file.
6416 * Created client_prvmsg.c and moved all private message and
6417 private message key routines from the client.[ch] into that file.
6419 * Create client_channel.c and moved all channel message and
6420 channel private key routines from the client.[ch] into that file.
6422 * Changed silc_client_get_client_by_id_resolve to resolve with
6423 WHOIS command instead of IDENTIFY command, in the file
6424 lib/silclient/idlist.c.
6426 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6428 * Implemented the SKE's responder side to the Client library.
6430 * When FAILURE is received to the protocol do not trust it
6431 blindly. Register a timeout to wait whether the remote closes
6432 the connection as it should do it, only after that process the
6433 actual failure. This was changed to both client and server.
6435 * Added client_internal.h to include some of the structures
6436 there instead of client.h in lib/silcclient/.
6438 * Added function silc_task_unregister_by_callback to unregister
6439 timeouts by the callback function.
6441 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6443 * Some "Incomplete WHOIS info" errors has been appearing on the
6444 log files. Took away the entry->userinfo check from WHOIS
6445 reply sending. The entry->userinfo is now " " if client did not
6446 provide one. I thought this was fixed earlier but something
6447 is wrong still. Let's see if the error still appears.
6449 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6451 * Fixed a minor bug in the login when the channel key is
6452 re-generated in the server. It used to generate the key in
6453 wrong order and thus caused problems in the channel traffic.
6455 * Fixed a minor bug in channel key distsribution after
6456 KICK command. The key was not sent to the router even though
6459 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6461 * Added silc_ske_process_key_material_data as generic routine
6462 to process any key material as the SILC protocol dictates. The
6463 function is used by the actual SKE library but can be used by
6464 applications as well. This relates to the private message keys
6465 and the channel private keys since they must be processed the
6466 same way the normal SILC session keys. The protocol dictates
6467 this. Affected files: lib/silcske/silcske.[ch].
6469 Added also silc_ske_free_key_material to free the
6470 SilcSKEKeyMaterial structure.
6472 * Defined silc_cipher_set_key function to set the key for
6473 cipher without using the object's method function. The affected
6474 files: lib/silccrypt/silccipher.[ch].
6476 * Implemented silc silc_client_add_private_message_key,
6477 silc_client_add_private_message_key_ske,
6478 silc_client_del_private_message_key,
6479 silc_client_list_private_message_keys and
6480 silc_client_free_private_message_keys functions in the
6483 Added functions silc_client_send_private_message_key to send
6484 the Private Message Key payload and silc_client_private_message_key
6485 to handle incoming Private Message Key payload.
6487 * Added Cipher field to the Private Message Key payload to set
6488 the cipher to be used. If ignored, the default cipher defined
6489 in the SILC protocol (aes-256-cbc) is used.
6491 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6493 * Removed lib/silcclient/ops.h file.
6495 Redefined parts of the SILC Client Library API. Created new
6496 file silcapi.h that deprecates the ops.h file and defines the
6497 published Client Library API. Defined also private message key
6498 API and channel private key API into the file.
6500 This is the file that the application must include from the
6501 SILC Client Library. Other files need not be included by
6502 the application anymore.
6504 * Added new key_agreement client operation callback and also
6505 defined the Key Agreement library API for the application.
6507 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6509 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
6510 is used by clients to request key negotiation between another
6511 client in the SILC network. If the negotiation is started it
6512 is performed using the SKE protocol. The result of the
6513 negotiation, the secret key material, can be used for example
6514 as private message key.
6516 Implemented the Key Agreement payload into the files
6517 lib/silccore/silauth.[ch].
6519 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6521 * Redefined ciphers for the SILC protocol. Added some new ciphers
6522 and defined the key lengths for the algorithms. Changed the
6523 code accordingly. The default key length is now 256 bits.
6525 * Fixed SKE key distribution function silc_ske_process_key_material
6526 when the key length is more than 128 bits. The default key
6527 length in SILC is now 256 bits.
6529 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
6530 to indicate unsupported algorithm.
6532 * Renamed rijndael.c to aes.c and all functions as well.
6534 * Fixed a long standing channel key setting bug in client library.
6535 Weird that it has never surfaced before.
6537 * Fixed bug in channel deletion. If the entire channel is removed
6538 then it must also delete the references of the channel entry
6539 from the client's channel list as the client's channel entry and
6540 the channel's client entry share same memory.
6542 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6544 * Implemented CONNECT and SHUTDOWN commands in the client.
6546 * Implemented CLOSE command to the client.
6548 * Added the function silc_idlist_find_server_by_name into the
6549 files silcd/idlist.[ch].
6551 Added the function silc_idlist_find_server_by_conn into the
6552 files silcd/idlist.[ch].
6554 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6556 * DIE command was renamed to SHUTDOWN. Updated the both code
6559 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
6560 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
6562 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
6565 * Added function silc_server_create_connection function to create
6566 connection to remote router. My server implementation actually
6567 does not allow router to connect to normal server (it expects
6568 that normal server always initiates the connection to the router)
6569 so the CONNECT command is only good for connecting to another
6572 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6574 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
6575 or some other client was kicked from the channel.
6577 Implemented the handling of the notify type to both client
6580 Implemented silc_server_send_notify_kicked to send the KICKED
6581 notify. It is used to send it to the server's primary router.
6583 * Implemented the KICK command into server and client.
6585 * Added `query' argument to the silc_idlist_get_client function
6586 to indicate whether to query the client from server or not if
6589 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
6590 to indicate that the client is not channel founder.
6594 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6596 * Removed the rng context from SilcPacketContext structure and
6597 changed that the packet routine uses the Global RNG API.
6599 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6601 * Added support for quit message that client can "leave" on the
6602 channel when it quits the SILC. It is ditributed inside the
6603 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6605 Added silc_server_free_client_data that will take the
6606 signoff message as argument.
6608 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6610 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6612 * Updated parts of the protocol specification to keep it up
6615 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6617 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6618 payloads in one packet.
6620 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6621 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6622 use now the new List flag.
6624 * Also deprecated the following packet types: REPLACE_ID,
6625 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6627 * Added list support for Notify packet in server.
6629 * Added silc_server_send_notify_channel_change to send the
6630 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6631 the silc_server_send_replace_id.
6633 * Added silc_server_send_notify_nick_change to send the
6634 NICK_CHANGE notify type. Deprecates the function
6635 silc_server_send_replace_id.
6637 * Added silc_server_send_notify_join to send the JOIN notify type.
6638 Deprecates the function silc_server_send_new_channel_user.
6640 * Added silc_server_send_notify_leave to send LEAVE notify type.
6641 Deprecates the function silc_server_send_remove_channel_user.
6643 * Added silc_server_send_notify_cmode and
6644 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6645 types. Deprecates the silc_server_send_set_mode function.
6647 * Added SERVER_SIGNOFF notify type to indicate that server has
6648 quit. This means that all clients on the channel from that
6649 server will drop. This can be also used when netsplit happens.
6651 Deprecated REMOVE_ID packet type since it is not needed anymore
6654 Added silc_server_send_notify_server_signoff to send the
6655 SERVER_SIGNOFF notify type. Deprecates the function
6656 silc_server_send_remove_id.
6658 Added also silc_server_send_notify_signoff to send the
6659 SIGNOFF notify type.
6661 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6662 SILC protocol from this day on. Changed the protocol
6663 specification as well.
6665 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6666 notify type. It is used between routers to notify about
6667 topic changes on a channel.
6669 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6672 * Partly updated the protocol specification to comply with the
6673 changes now made. It is still though a bit outdated.
6675 * The JOIN notify type now takes one extra argument <Channel ID>.
6676 The packet used to be destined to the channel but now the
6677 JOIN type may be sent as list thus it is impossible to
6678 destine it to any specific channel. By adding this argument
6679 it is again possible.
6681 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6683 * Added CREDITS file. The CHANGES and CREDITS file will appear
6684 in the distribution as well.
6686 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6688 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6689 types in the server's silcd/packet_receive.c.
6691 * Implemented CMODE and CUMODE to work in router environment.
6693 * Fixed minor encoding and decoding buglet from the
6694 lib/silccore/silcmode.c.
6696 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6699 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6701 * Changed all SilcConfigServer* and silc_config_server* to
6702 SilcServerConfig* and silc_server_config*, respectively.
6705 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6707 * Associated the ID (client or server ID) to the Authentication
6708 Payload to avoid any possibility of forging. Updated the
6709 protocol specification and the code accordingly.
6711 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6713 * The RSA key length is now save to the RsaKey context in the
6714 key generation process in lib/silccrypt/rsa.c. The key length
6715 is now used to figure out the maximum size of the block allowed
6716 to be encrypted/signed.
6718 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6719 is equivalent to the silc_mp_mp2bin but does not allocate any
6722 * Changed silc_mp_mp2bin API to take length argument. If it is
6723 non-zero then the buffer is allocated that large. If zero, then
6724 the size is approximated using silc_mp_sizeinbase, which however
6727 * Created Global RNG API which is global RNG that application can
6728 initialize. After initializing, any routine anywhere in the
6729 code (including library) can use RNG without allocating a new
6730 RNG object. This was done to allow this sort of use of the
6731 RNG in code that has no chance to allocate RNG object. All
6732 applications currently allocate this and many routines in the
6733 library use this. Affected file lib/silccrypt/silcrng.[ch].
6735 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6736 it to use the Global RNG API.
6738 * Defined Authentication Payload into protocol specification that
6739 is used during SILC session to authenticate entities. It is
6740 used for example by client to authenticate itself to the server
6741 to obtain server operator privileges.
6743 Implemented this payload into the lib/silccore/silcauth.[ch].
6744 Implemented also routines for public key based authentication
6745 as the new protocol specification dictates.
6747 Moved definitions of different authentication methods from
6748 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6750 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6751 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6752 silc_pkcs_verify_with_hash functions into the file
6753 lib/silccrypt/silcpkcs.[ch].
6755 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6757 * The client entry's userinfo pointer must be always valid.
6758 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6759 will fail since it requires the userinfo. Now, the userinfo
6760 is allocated as "" if actual userinfo does not exist. Actually,
6761 it must exist and it is totally Ok to drop client connections
6762 that does not announce the userinfo. However, we will make
6763 this workaround for now.
6765 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6766 to return the remote port by socket.
6768 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6770 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6771 SILC_SERVER_PENDING_EXEC and added an new macro
6772 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6773 data or when error occurs while processing the pending command.
6775 Added new argument `destructor' into silc_server_command_pending
6776 and to the SilcServerCommandPending object. This destructor is
6777 now called after calling the pending callback or if error occurs
6778 immediately. If error occurs the actual pending callback won't
6779 be called at all - only the destructor. The destructor may be
6780 NULL if destructor is not needed.
6782 All this applies for client library code as well. Similar
6783 changes were made there as well for the pending commands.
6785 In the client, the application must now allocate the
6786 SilcClientCommandContext with the silc_client_command_alloc
6789 * Added reference counter to the SilcServerCommandContext. Added
6790 function silc_server_command_alloc and silc_server_command_dup
6793 Same type of functions added to the client library for the same
6796 * Removed the cmd_ident from IDListData away since it is now
6797 global for all connections. It is the command identifier used
6798 in command sending and with pending commands. The affected file
6801 * Added reference counter to the SilcSocketConnection objecet to
6802 indicate the usage count of the object. The object won't be
6803 freed untill the reference counter hits zero. Currently only
6804 server uses this, and client ignores it. The client must be
6805 set to use this too later. The affected files are
6806 lib/silccore/silcsockconn.[ch]. Added also the function
6807 silc_socket_dup to increase the reference counter.
6809 This was mainly added because it is possible that the socket
6810 is removed underneath of pending command or other async
6811 operation. Now it won't be free'd and proper DISCONNECTING
6812 flags, etc. can be set to avoid sending data to connection that
6813 is not valid anymore.
6815 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6816 the connection. After that it sets SILC_SET_DISCONNECTED.
6817 It is, however, possible that the socket data is not still freed.
6818 The silc_server_packet_process now checks that data is not
6819 read or written to connection that is DISCONNECTED. The socket
6820 get's freed when the reference counter hits zero.
6822 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6824 * Changed the client operation API: channel_message operation's
6825 `sender' is now the client entry of the sender, not the nickname
6826 and the `channel' is the channel entry, not the channel name.
6828 In the private_message operation the `sender' is now also the
6829 client entry of the sender not the nickname.
6831 Affected file is lib/silcclient/ops.h and all applications
6832 using the client operations.
6834 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6836 * Moved the calling of ops->connect() from connect_to_server_final
6837 into receive_new_id functin since that is the point when the
6838 client is actually allowed to send traffic to network. The
6839 affected file is lib/silcclient/client.c.
6841 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6843 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6844 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6845 (if needs broadcasting) instead of broadcasting the packets one
6846 by one which would make a burst in the network traffic.
6848 * Added `broadcast' argument to the functions in silcd/server.[ch]
6849 silc_server_create_new_channel[_with_id] to indicate whether
6850 to send New Channel packet to primary router.
6852 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6854 * Added new function into the silcd/server.[ch] files:
6855 silc_server_create_new_channel_with_id to create new channel with
6856 already existing Channel ID.
6858 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6859 lib/silccore/silcpacket.h. This packet is used t send list of
6860 Set Mode payloads inside one packet. Server uses this to set
6861 the modes for the channels and clients on those channels, that it
6862 announced to the router when it connected to it. The protocol
6863 specification has been updated accordingly.
6865 * The silc_server_new_channel did not handle the packet coming
6866 from normal server as it normally does not send that. However,
6867 when it announces its channels it does send it. Implemented
6868 the support for that.
6870 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6871 into the file lib/silccore/id.h.
6873 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6875 * Fixed memory leaks in the functions silc_idlist_del_client,
6876 silc_idlist_del_channel and silc_idlist_del_server in the file
6877 silcd/idlist.c. All of those leaked like a sieve.
6879 * Fixed some small memory leaks in the client's function
6880 silc_client_notify_by_server.
6882 * Added functions into silcd/server.c: silc_server_announce_clients,
6883 silc_server_announce_channels and silc_server_announce_server.
6884 These functions are used by normal and router server to announce
6885 to its primary router about clients, channels and servers (when
6886 router) that we own. This is done after we've connected to the
6889 These functions effectively implements the following packet types:
6890 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6891 and SILC_PACKET_NEW_ID_LIST.
6893 * Added new functions into the silcd/packet_receive.[ch]:
6894 silc_server_new_id_list, silc_server_new_channel_list and
6895 silc_server_new_channel_user_list to handle the incoming
6896 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6898 * Added support of changing Channel ID in the function
6899 silc_server_replace_id. If the server that announces a channel
6900 to the router already exists in the router (with same name but
6901 with different Channel ID), router is responsible to send
6902 Replace ID packet to the server and force the server to change
6903 the Channel ID to the one router has.
6905 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6906 client that the Channel ID has been changed by the router. The
6907 normal server sends this to the client. Client must start using
6908 the new Channel ID as the channel's ID.
6910 Implemented handling of this new type into lib/silcclient/client.c
6911 into the function silc_client_notify_by_server.
6913 * Added new function silc_idlist_replace_channel_id into the files
6914 silcd/idlist.[ch] to replace the Channel ID.
6916 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6918 * Call silc_server_command_identify_check always when processing
6919 the IDENTIFY command in silcd/command.c
6921 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6923 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6924 send keepalive packets. The packet can be sent by clients,
6925 servers and routers.
6927 Added function silc_socket_set_heartbeat into the file
6928 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6929 If not set, the heartbeat is not performed. The actual
6930 heartbeat is implemented in the low level socket connection
6931 library. However, application is responsible of actually
6934 Added silc_server_send_heartbeat to send the actual heartbeat
6935 packet into silcd/packet_send.[ch]. Server now performs
6936 keepalive with all connections.
6938 * Added silc_task_get_first function into lib/silcutil/silctask.c
6939 to return the timeout task with shortest timeout. There was a bug
6940 in task unregistration that caused problems. TODO has been
6941 updated to include that task system must be rewritten.
6943 * The client library will now resolve the client information when
6944 receiving JOIN notify from server for client that we know but
6945 have incomplete information.
6947 * Rewrote parts of silc_server_remove_from_channels and
6948 silc_server_remove_from_one_channel as they did not remove the
6949 channel in some circumstances even though they should've.
6951 * Encryption problem encountered in server:
6953 The LEAVE command used to send the Channel Key packet to the
6954 router immediately after generating it. However, the code
6955 had earlier sent Remove Channel user packet but not immediately,
6956 ie. it was put to queue. The order of packets in the router
6957 was that Channel Key packet was first and Remove Channel User
6958 packet was second, even though they were encrypted in the
6959 reverse order. For this reason, MAC check failed. Now, this
6960 is fixed by not sending the Channel Key packet immediately but
6961 putting it to queue. However, this is more fundamental problem:
6962 packets that are in queue should actually not be encrypted
6963 because packets that are sent immediately gets encrypted
6964 actually with wrong IV (and thus MAC check fails). So, packets
6965 that are in queue should be encrypted when they are sent to
6966 the wire and not when they put to the queue.
6968 However, the problem is that the current system has not been
6969 designed to work that way. Instead, the packet is encrypted
6970 as soon as possible and left to the queue. The queue is then
6971 just purged into wire. There won't be any fixes for this
6972 any time soon. So, the current semantic for packet sending
6975 o If you send packet to remote host and do not force the send
6976 (the packet will be in queue) then all subsequent packets to the
6977 same remote host must also be put to the queue. Only after the
6978 queue has been purged is it safe again to force the packet
6981 o If you send all packets immediately then it safe to send
6982 any of subsequent packets through the queue, however, after
6983 the first packet is put to queue then any subsequent packets
6984 must also be put to the queue.
6986 Follow these rules and everything works fine.
6988 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6990 * Added new function silc_server_remove_clients_by_server to
6991 remove all client entries from ID list when the server connection
6992 is lost. In this case it is also important to invalidate all
6993 client entires as they hold the invalid server entry. This
6994 fixes fatal bug when server has lost connection and will reconnect
6997 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6999 * Made some sanity checks to silc_server_daemonise like to check
7000 whether the requested user and group actually exists.
7002 * Added sanity check to SKE's silc_ske_responder_finish to check
7003 that the public and private key actually is valid.
7005 * Invalidate the client's nickname when receiving Replace ID
7006 packet and the Client ID is being replaced. This means that the
7007 server will query the nickname if someone needs it (client)
7010 * Sort the ID Cache in client library when the ID Cache data
7011 has changed (needs sorting).
7013 * Do not allow for SILC client to create several connections to
7014 several servers. The client does not support windows right now
7015 and generating multiple connections causes weird behaviour.
7017 Irssi-silc client does support windows and can handle several
7018 connections without problems, see: www.irssi.org and SILC plugin.
7020 * Fixed some places where client was added to the IDList. The
7021 rule of thumb is following (in order to get everything right):
7022 If the client is directly connected local client then the
7023 `connection' argument must be set and `router' argument must be
7024 NULL to silc_idlist_add_client function. If the client is not
7025 directly connected client then the `router' argument must
7026 bet set and the `connection' argument must be NULL to the
7027 silc_idlist_add_client function.
7029 * The funtion silc_server_packet_send_local_channel actually did
7030 not check whether the client was locally connected or not. It
7031 does that now. Fixed a bug related to LEAVE command.
7033 * Fixed Remove Channel User payload parsing bug in server's
7034 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
7036 * The server's silc_server_save_channel_key now checks also the
7037 global ID list for the channel as it might not be in the local
7038 list. Fixed a bug related to LEAVE command.
7040 * Is this the end of the [<unknown>] buglet that has been lurking
7041 around for a long time? A little for loop fix in server's
7042 silc_server_command_whois_parse that is used by both IDENTIFY
7043 and WHOIS command. At least, this was a clear bug and a cause
7044 of one type of [<unknown>] buglet.
7046 * WHOIS and IDENTIFY commands call the function
7047 silc_server_command_[whois/identify]_check function even if
7048 we are not router server.
7050 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7052 * Added --with-gmp configuration option. If set the GMP
7053 is always compiled in the SILC source tree. If not set then
7054 it is checked whether the system has the GMP3 installed. If
7055 it has then the GMP won't be compiled (the system's headers
7056 and library is used), if it doesn't have it then the GMP is
7057 compiled in the SILC source tree.
7059 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7061 * Changed RSA private exponent generation to what PKCS #1
7062 suggests. We try to find the smallest possible d by doing
7063 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
7064 not security fix but optimization.
7066 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7068 * Added new config entry [Identity] to fork the server and run
7069 it as specific user and group. A patch from Bostik.
7071 * Imported Dotconf configuration library into lib/dotconf.
7072 This will be used to create the SILC configuration files later.
7073 It will appear in the distsribution after this commit.
7075 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7077 * A big code auditing weekend happening. Auditing code for
7078 obvious mistakes, bugs and errors. Also, removing any code
7081 Removed files for being obsolete:
7083 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
7084 inline in the file lib/silcutil/silcbuffer.h)
7086 o lib/silcutil/silcbufutil.c (the header has inline versions)
7088 Changed code to fix possible error conditions:
7090 o The buffer formatting routines now check that the destination
7091 buffer really has enough space to add the data. This applies for
7092 both buffer formatting and unformatting
7093 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
7094 unformatting was changed to accomodate following rules:
7095 XXX_*STRING_ALLOC will allocate space for the data into the pointer
7096 sent to the function while XXX_*STRING will not allocate or copy
7097 the data into the buffer. Instead it sets the pointer from the
7098 buffer into the pointer sent as argument (XXX_*STRING used to
7099 require that the pointer must be allocated already). This change
7100 makes this whole thing a bit more consistent and more optimized
7101 (note that the data returned in the unformatting with XXX_*STRING
7102 must not be freed now). The routines return now -1 on error.
7104 o Tried to find all code that use buffer_format and buffer_unformat
7105 and added return value checking to prevent formatting and
7106 especially unformatting errors and possible subsequent fatal
7109 o Changed ske->x and ske->KEY to mallocated pointers in
7110 lib/silcske/silcske.h. Fixed possible data and memory leak.
7112 o Added return value checking to all *_parse* functions. Fixed
7113 many memory leaks as well.
7115 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
7116 so that buffer overflows would not happen. All code now also
7117 checks the return value as it can fail.
7119 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7121 * Added reconnection support to server if the normal server looses
7122 its connection to the router (for example if router is rebooted).
7123 The server performs normal reconnection strategy implemented
7124 to the server. Affected file silcd/server.c.
7126 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7128 * Added new packet type SILC_PACKET_SET_MODE that is used to
7129 distribute the information about changed modes (for clients,
7130 channels and clients channel modes) to all routers in the
7131 network. Updated the protocol specification accordingly.
7133 Added functions into silcd/packet_send.c and
7134 silcd/packet_receive.c: silc_server_send_set_mode,
7135 silc_server_set_mode.
7137 Added new files silcmode.[ch] into lib/silccore that implements
7138 the encoding and decoding of Set Mode Payload. Added new type
7139 SilcSetModePayload. Moved the definitions of different modes
7140 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
7142 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7144 * Oops, a little mistake in server's connection authentication
7145 protocol. The protocol is not ended with FAILURE but with
7146 SUCCESS if the authentication is Ok. :) Affected file is
7149 * Implemented NICK_CHANGE notify handling in server in the file
7150 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
7151 the local clients on the channel. After the changing nickname
7152 in router environment snhould work and the [<unknown>] nickname
7153 should appear no more.
7155 The silc_server_replace_id function that receives the Replace ID
7156 payload now sends the NICK_CHANGE notify type also in the file
7157 silcd/packet_receive.c
7159 * Changed WHOIS and IDENTIFY command to support the maximum amount
7160 of arguments defined in protocol specs (3328 arguments). This
7161 fixed a bug that caused problems when there were more than three
7164 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7166 * Added extra parameter, command identifier, to the
7167 silc_client_send_command so that explicit command identifier
7170 Changed that ID list routines uses specific command identifier
7171 when sending WHOIS/IDENTIFY requests to the server so that they
7172 can be identified when the reply comes back.
7174 Affected files lib/silcclient/command.[ch],
7175 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
7177 * Added `sender' argument to silc_server_packet_send_to_channel
7178 to indicaet the sender who originally sent the packet to us
7179 that we are now re-sending. Ignored if NULL. Affected file
7180 silcd/packet_send.[ch].
7182 * Added some server statistics support in silcd/server_internal.h
7183 SilcServerStatistics structure and around the server code. Also
7184 send some nice statistics information when client is connecting
7187 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7189 * Fixed channel ID decoding in server's JOIN command reply in
7190 silcd/command_reply.c
7192 * Fixed braodcasting of replace ID payload to not to send it if
7193 we are standalone server in silcd/packet_receive.c.
7195 * Fixed all channel message sending routines to not to send
7196 packets to clients that has router set, since they are routed
7197 separately in the same function earlier. Affects file
7198 silcd/packet_send.c and all channel packet sending functions.
7200 * In USERS reply, res_argv[i] are not allocated, the table
7201 is allocated. Thus changed that free the table, not its
7204 * In server's whois_check and identify_check if the client is
7205 locally connected do not send any WHOIS commands - they are not
7208 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7210 * Fixed some minor bugs in client when sending WHOIS command. The
7211 arguments was in wrong order.
7213 * Removed statis function add_to_channel from server in
7214 silcd/command.c that was previously used with the joining but
7217 * Tested USERS command in router environment successfully with two
7218 routers, two servers and two clients.
7220 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7222 * Reorganized the USERS command and command reply in client library
7223 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
7224 When the command is given by user we register a pending command
7225 callback that will reprocess the command after the reply has been
7226 received from the server. When reprocessing the packet we then
7227 display the information. Thus, the USERS information is displayed
7228 now in the command callback instead of in the command reply
7229 callback. The processing of the command is same as previously
7230 when server has sent the command reply in the JOINing process.
7232 * Added to USERS command in silcd/command_reply.c to join the client,
7233 we didn't use to know about, to the channel after we've created
7234 a client entry for it. Also, for clienet we did know already still
7235 check whether it is on the channel or not and add it if not.
7237 * Removed silc_server_command_join_notify as the function and its
7240 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7242 * Changed the client's pending command handling to the same as the
7243 server's pending command handling. It is also now possible to
7244 execute command reply functions from other command reply
7245 function as the function callbacks for commands and command
7246 replies are one and same. The pending commands are not static
7247 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
7248 in client connection context. Thus, pending commands are server
7249 connection specific as it is convenient.
7251 Changed the function silc_client_command_pending and
7252 silc_client_command_pending_del and added new function
7253 silc_client_command_pending_check. Removed the
7254 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
7257 * Added cmd_ident, current command identifier, to the client
7258 connection context in lib/silcclient/client.h to keep track on
7259 command identifiers used in command sending. Client's command reply
7260 function handling now supports the mandatory command identifiers.
7262 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
7263 funtions in client to fully support pending command callbacks.
7265 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
7266 as one of the arguments to the application in the command reply
7269 * NOTE: The FORWARDED flag is depracated. It used to be depracated
7270 before first releasing SILC but came back. Now it is removed again
7271 and should come back nomore. The FORWARDED flag was used only
7272 by the JOINing procedure by forwarding the command packet to router.
7273 Now, the JOINing procedure has been changed to more generic (due
7274 to various router environment issues) and FORWARDED is not needed
7275 anymore for anything. The protocol specification is yet to be
7278 Now, removed silc_server_packet_forward from server and the flag
7279 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
7281 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7283 * Renamed NAMES command to USERS command. The NAMES was named that
7284 due to historical reasons. Now it is renamed. Also, rewrote
7285 parts of the USERS command. The nickname list is not sent anymore
7286 by the server. Only Client ID and mode lists are sent in the USERS
7287 command. Changed this also to the protocol specification.
7289 The client now resolves the names and stuff after it receives
7290 the USERS list from the server when joining to the channel.
7292 * WHOIS and IDENTIFY commands has been changed to support multiple
7293 Client ID's per command. One can now search for multiple users
7294 in the network by sending only one WHOIS or IDENTIFY command.
7295 Changed the code and the protocol specifications.
7297 * Removed silc_server_command_identify_parse and changed that IDENTIFY
7298 uses silc_server_command_whois_parse to parse the request. */
7300 * If normal server, do not parse the WHOIS and IDENTIFY requests
7301 before sending it to the router. Saves some time.
7303 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7305 * Fixed JOIN command on client library. Wrong number of arguments
7306 used to crash the client.
7308 * Added silc_server_channel_has_global function to check whether
7309 channel has global users or not.
7311 * Added silc_server_channel_has_local function to check whether channel
7312 has locally connected clients on the channel.
7314 * The silc_server_remove_from_one_channel now checks whether the
7315 channel has global users or not after given client was removed from
7316 the channel. It also checks whether the channel has local clients
7317 on the channel anymore. If it does not have then the channel entry
7318 is removed as it is not needed anymore.
7320 * The silc_server_notify now checks on JOIN notify whether the joining
7321 client is one of locally connected or global. If it is global then
7322 the channel has now global users on the channel and that is marked
7323 to the channel entry. Also, it now saves the global client to
7324 global list who is joining and JOINs it to the channel. This is
7325 for normal server, that is.
7327 Changed silc_server_send_notify_on_channel,
7328 silc_server_packet_relay_to_channel and
7329 silc_server_packet_send_to_channel check if we are normal server
7330 and client has router set (ie. global client) do not send the
7331 message to that client, as it is already routed to our router.
7333 * Implemented LEAVE notify type handling in silc_server_notify
7336 * Tested LEAVE command in router environment successfully. Tested
7337 with two routers, two servers and two clients.
7341 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
7343 * Implemented SIGNOFF notify type handling in silc_server_notify
7346 * silc_server_remove_id now removes the client entry from all channels
7347 it has joined and thusly sends SIGNOFF notify type.
7349 * Rewrote the NAMES list generation in server by removing two excess
7350 loops. The lists are created now inside one loop.
7352 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7354 * silc_server_remove_channel_user checks now also global list
7355 for channel and client.
7357 * silc_server_new_channel_user checks now both local and global
7358 list for channel and client. Fixed a bug in client id decoding.
7359 Used to decode wrong buffer.
7361 * silc_server_channel_message checks now both local and global
7362 list for channel entry.
7364 * Tested channel joining (hence JOIN) in router environment
7365 successfully. Tested with two routers, two servers and two
7368 * Tested channel message sending in router environment successfully.
7370 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7372 * Added silc_server_save_channel_key into server.[ch] to save the
7373 received channel key in Channel Key payload processing. It is
7374 also used in JOIN command reply handling.
7376 Equivalent function silc_client_save_channel_key added into
7377 client.[ch] into client library.
7379 * Changed JOIN command reply to send information whether the channel
7380 was created or not (is existing already) and the channel key
7381 payload. Changed protocol specs accordingly.
7383 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
7384 the request was sent by ID and not by nickname. Crashed on
7387 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7389 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
7390 now correctly save the received data.
7392 * silc_server_free_sock_user_data now notifies routers in the
7393 network about entities leaving the network.
7395 At the same time implemented functions silc_server_remove_id
7396 and silc_server_send_remove_id to receive and send REMOVE_ID
7397 packets. The packet is used to notify routers in the network
7398 about leaving entities. The ID removed will become invalid in
7401 * Added function silc_idlist_del_server into server. Removes and
7402 free's server entry from ID list.
7404 * silc_server_private_message function now checks, if we are router,
7405 that the destination ID really is valid ID, naturally.
7407 * In router when NEW_ID packet is received (for new client) the
7408 hash of the Client ID is saved in the ID Cache but the
7409 client->nickname is set to NULL, instead of putting the hash
7412 IDENTIFY command now also checks that client->nickname must be
7413 valid. If it is not if will request the data from the server who
7414 owns the client. Added new function
7415 silc_server_command_identify_check.
7417 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
7418 to set the command to already allocated Command Payload.
7420 * Tested private message sending in router environment with two
7421 routers, two servers and two clients. Fixed minor bugs and now
7424 * Fixed segfault from client's NAMES command. Used to crash if
7427 * Forwarded packets must not be routed even if it is not destined
7428 to the receiver. Changed server code comply with this.
7430 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7432 * Added `require_reverse_mapping' boolean value to ServerParams
7433 structure. If TRUE (not default) the server will require that
7434 the connecting host has fully qualified domain name.
7436 If the reverse mapping is not required and hostname could not be
7437 found the IP address is used as hostname.
7439 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7441 * Implemented version string checking to both client and server.
7442 The check is incomplete currently due to the abnormal version
7443 strings used in development version of SILC.
7445 * Changed all command functions in server to use the new
7448 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7450 * Changed char *data to unsigned char *data in ID Cache system to
7451 support binary data as ID Cache data. Changed code to support
7452 binary data in lib/silccore/idcache.c.
7454 * Renamed silc_server_packet_relay_command_reply to
7455 silc_server_command_reply as it is normal packet receiving
7456 function. Rewrote the function to accept command replys for
7457 servers and not only for clients.
7459 * Mark remote router always as registered server if we are connecting
7460 to it. Otherwise, commands sent by the router to us are ignored.
7462 * All ID List find routines now returns the ID Cache Entry pointer
7463 as well if requested.
7465 * WHOIS command works now in router environment, tested with two
7466 routers, two servers and two clients.
7468 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
7469 in router environment (as it is almost equivalent to WHOIS) but
7470 hasn't been tested thoroughly. Added new functions:
7472 silc_server_command_identify_parse
7473 silc_server_command_identify_send_reply
7474 silc_server_command_identify_from_client
7475 silc_server_command_identify_from_server
7477 * Disabled route cache adding because adding two different ID's with
7478 same IP replaces the old cache entry thus giving wrong route.
7479 The entry->router->connection is always the fastest route anyway
7480 so route cache may not be needed. Of course, new routes maybe
7481 established after receiving the ID when the entry->router->connection
7482 might not be anymore the most optimal.
7484 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7486 * Add route cache for received ID for fast routing.
7488 * Added silc_server_packet_route to route received packet on router
7489 that is not destined to us.
7491 * Renamed silc_server_get_route to silc_server_route_get.
7493 * Added id_string and id_string_len fields into SilcServer to
7494 include encoded ServerID for fast comparing without excess
7495 encoding of the ID's.
7497 * Cleaned up WHOIS command on server side. Added following static
7500 silc_server_command_whois_parse
7501 silc_server_command_whois_check
7502 silc_server_command_whois_send_reply
7503 silc_server_command_whois_from_client
7504 silc_server_command_whois_from_server
7506 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
7507 arguments in command replies. All command functions should be
7508 updated to use this macro.
7510 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7512 * Minor typo fixes on command reply handling on server.
7514 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7516 * Added silc_server_command_add_to_channel internal routine to add
7517 the client to the channel after router has created the channel and
7518 sent command reply to the server.
7520 * Added generic silc_server_send_command to send any command from
7523 * Use static buffer with ID rendering instead of duplicating data.
7525 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7527 * Fixed a channel user mode bug when joining to a channel server gave
7528 everybody channel founder rights, oops.
7530 * We mark ourselves as the router of the incoming server connection
7531 if we are router ourselves. This way we can check in some packet
7532 sending functions whether it is locally connected server. For
7533 incoming router connections we put NULL.
7535 * For router sending packets locally means now always sending the
7536 packet cell wide; to local clients and local servers. For normal
7537 server sending packet locally means sending it to only local
7540 * Fixed the JOIN command to really work in router environment. If the
7541 channel is created it is always created by the router. Router is
7542 also responsible of making the initial joining to the channel,
7543 sending JOIN notify to the sending server and distributing
7544 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
7545 does not exist server doesn't do anything else but forward the
7546 command to the router which performs everything.
7548 * Added silc_server_send_channel_key function to send the Channel Key
7551 * Added silc_server_create_channel_key to create new channel key. The
7552 channel key is now re-generated everytime someone joins or leaves
7553 a channel, as protocol dictates. Note: channel->key_len is the
7556 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7558 * Splitted server.[ch] finally. Created now packet_send.[ch] and
7559 packet_receive.[ch] to separate packet sending and receiving
7560 routines. The server.[ch] now includes everything else including
7561 actual packet processing (writing and reading data) and other
7564 Renamed silc_server_private_message_send_internal to
7565 silc_server_send_private_message. The routine is still though
7566 used only to relay private messages as server does not send
7567 private messages itself.
7569 Renamed silc_server_new_channel to silc_server_create_new_channel
7570 and added new function sicl_server_new_channel that handles the
7571 incoming New Channel packet. Added also new sending function
7572 silc_server_send_new_channel to send New Channel Payload.
7574 * Added new function silc_server_notify to process incoming notify
7575 packet to the server/router. Server may then relay the notify
7576 to clients if needed.
7578 * Added new function silc_server_new_channel_user to process incoming
7579 New Channel User packet. Router will redistribute the packet and
7580 send JOIN notify to its local clients and locally connected servers
7581 if needed. Normal server will send JOIN notify to its local client
7582 on same channel when received this packet. Added also corresponding
7583 sending function silc_server_send_new_channel_user to sent the
7586 * Added boolean route argument to send_notif_to_channel and
7587 packet_send_to_channel functions to attempt to route the packet
7588 if it is TRUE and send only locally if it is FALSE.
7590 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7592 * silc_server_replace_id now broadcasts the received replace ID
7593 packet if it is not broadcast packet already. The router must
7594 broadcast to inform other routers about changed ID.
7596 * Added backpointer to server's router into SilcServer context in
7597 silcd/server_internal.h.
7599 * Fixed silc_server_packet_broadcast to send correct broadcast
7602 * The channel key is now distributed to the local client as soon
7603 as it is received from the router (in router environment) so that
7604 no other packet may be sent for the channel until client has
7607 * silc_server_remove_channel_user now broadcasts the received
7608 Remove Channel User packet if it is not broadcast packet already.
7609 The router must broadcast to inform other routers about removed
7612 * Added users field into SilcPacketContext that is a reference count
7613 of the context. One can increase the reference count by calling
7614 silc_packet_context_dup which is now changed to just increase the
7615 reference count instead of duplicating the data. The reference
7616 count is decresed by calling silc_packet_context_free that will
7617 free the data after the reference count hits zero.
7619 For now on the packet context and everything allocated into it
7620 (including the raw packet from network) must be freed by calling
7621 the new silc_packet_context_free function. Added also new function
7622 silc_packet_context_alloc that must be used now to allocate the
7623 context. This also means that if a routine is asynchronous from
7624 silc_[client/server]_packet_parse_type the packet context must
7625 be duplicated by calling silc_packet_context_dup. Otherwise it
7626 gets free'd after silc_[client/server]_packet_parse_type returns.
7627 Also, one must remember that if packet is duplicated then its
7628 reference count must be decresed by calling the free function as
7629 many times as it was duplicated.
7631 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7632 from both client and server.
7634 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7636 * Made joining to a channel working in router environment.
7638 * Cleaned up JOIN command on server side and create function
7639 silc_server_command_join_channel internal routine to make the
7642 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7644 * Changed silc_command_pending list to SilcDList. Also, added
7645 `ident' field to SilcServerCommandPending structure to identify
7646 the reply and to call correct callback.
7648 Added silc_server_command_pending_check function to replace the
7649 corresnponding macro. The silc_command_pending list is not
7652 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7653 to set identifier to previously allocated Command Payload. It
7654 is used to set identifier for command when resending Command
7657 * Added silc_command_payload_encode_payload to encode Command
7658 Payload buffer from SilcCommandPayload structure.
7660 * Added silc_argument_payload_encode_payload to encode Argument
7661 payload buffer from SilcArgumentPayload structure.
7663 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7665 * Changed WHOIS command to support router connection on server side.
7666 The whois request is always sent to router unless the server is
7667 standalone server. After server has received the reply from the
7668 router will it send the reply to the client.
7670 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7671 broadcast received broadcast packet. The function is used only
7672 by router. The broadcast packet is always sent to the router's
7675 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7676 render given ID to printable string, for log files for example.
7678 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7680 * Made basic router to router connections working. At least they
7681 can now connect to each other but nothing really works the way
7682 they are supposed - yet.
7684 * Added new initiator token to RouterConnection configuration
7685 file in silcd/serverconfig.[ch]. It is used to tell whether we
7686 are the initiator to the remote router or whether we'll expect
7687 the other end to connect.
7689 * Moved registering of listener task to silc_server_init, hence
7690 the server starts listenning as soon as it is run, even if it
7691 does not have connections to other routers. Let's see how well
7694 * Changed default connection retry timeouts for more suitable in
7697 * Removed cipher and such arguments from silc_idlist_add_client
7698 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7699 Added new function silc_idlist_add_data to add the keys and stuff
7702 * Added SilcIDListData structure and added it to SilcClientEntry
7703 and SilcServerEntry as their first field in the structure. This
7704 way we can explicitly cast the ID entries to the SilcIDListData
7705 structure and get common data for the entries. In past, we had
7706 to first check what type of connection it is and then cast it to
7707 correct ID entry type. Now, we can directly cast the opaque
7708 pointer to the SilcIDListData (no matter what ID entry it actually
7709 is) and get the data needed.
7711 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7713 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7714 in some circumstances even if threre were timeout tasks, though not
7715 IO tasks, but tasks anyway. Now fixed.
7717 * Defined SilcServerConnection structure to hold connection specific
7718 stuff about directly connected servers and routers. The definition
7719 is currently in silcd/server_internal.h. I thought about having
7720 a bit more important role fro this struct but for now it is used
7721 only when connecting to other server (or router actually).
7723 * Added connecting retry support in server when connecting to
7724 router(s). The retry feature implement exponential backoff
7725 algorithm. Also, added SilcServerParams structure to hold default
7726 parameters for server. For now, it include these retry settings
7727 and are hard coded. After server is moded to be as Silc Server
7728 Library this structure will be more important.
7730 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7732 * Changed client librarys channel->clients table to SilcList and
7733 changed code accordingly.
7735 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7737 * Changed client's channel table to SilcList and changed code
7738 accordingly. Also changed SilcChannelClientEntry to include back-
7739 pointer to the channel so that client entry can use that structure
7740 as list as well and we have fast cross-reference to the channel.
7741 This change dramatically decreased the complexity of channel
7742 handling with client entry and vice versa (removed one extra
7743 loop when searching for channel entry from many functions).
7745 * Changed server->sim from table to SilcDList and changed code
7748 * NAMES command can now be used from user interface. It will show
7749 the user list on the channel, neatly.
7751 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7752 Code now saves realname of the user if it becomes available.
7754 * Renamed configure.in to configure.in.pre and made ./prepare
7755 script to automatically add correct version string to
7756 configure.in which it creates from configure.in.pre.
7758 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7760 * NAMES command reply now shows users mode with the nickname when
7763 * Moved silc_client_ch[u]mode[_char] functions from
7764 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7765 place sucks, they are utility functions and should be in some
7768 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7770 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7773 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7777 * Added TRQ (efficient deque and list library) into lib/trq. This is
7778 a very good list library that is currently used in the SILC. Defined
7779 SilcList API over the library because I didn't like the API very
7780 much. See lib/trq/silclist.h for the API and examples of how to
7781 use the API. Fixed various places in the code to use the new
7782 SilcList API. The SilcList is meant for lists that has a structure
7783 already defined as a list. It is not suitable to add just some
7784 context to the list (in TRQ, the context is the list actually).
7786 So, I defined SilcDList that can be used for the purpose where
7787 predefined list structure does not exit. This can be used as
7788 such list. Now some context just can be added to the SilcDList.
7789 Currently this list is not used in the SILC just yet, though there
7790 are a lot places where this can replace dynamically allocated
7791 tables and I will fix these places, later, to use SilcDList.
7792 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7793 and use TRQ internally).
7795 Also fixed some annoying warning messages that the original TRQ
7796 code generated. Also minor changes to TRQ's Makefile.in.
7798 * Added support for querying by Client ID to both WHOIS and
7799 IDENTIFY commands into server, as required by the protocol.
7801 * Removed method function pointers from SilcBuffer structure. They
7802 weren't used to anything and just increased the context size for
7803 no good reason. This change also made silc_buffer_alloc and
7804 silc_buffer_free functions inline functions.
7806 * Disabled command flooding detection support until it's fixed so
7807 that it accepts commands in but does not execute them more than once
7810 * Added silc_net_localhost(), to return local hostname, into
7811 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7812 that must be initialized before calling silc_client_init.
7814 * Added new function: silc_server_send_notify_on_channels to send
7815 notify messages to all channels client has joined. It is assured
7816 that the message is sent only once per client.
7818 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7819 lib/silcutil/silcutil.[ch] as silc_format function. The new
7820 function is generic and is used by server as well, not only by
7821 the logging routines.
7823 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7824 the provided version string was not acceptable. Added new function:
7825 silc_ske_check_version into lib/silcske/silcske.h. The function
7826 must be implemented by the application (client or server) and it
7827 does not reside in the SKE library. The function checks the version
7828 string remote end sent.
7830 * Added back pointers (to opaque context and to SilcSocketConnection)
7831 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7833 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7834 duplicate packet context structure.
7836 * Changed `notify' client operation to send same arguments as client
7837 receives from server except for ID's. ID's are mapped to correct
7838 ID entry and that is returned. Also, if channel entry is not sent
7839 by server but the notify is for channel the channel entry is sent
7840 to application (otherwise application doesn't know that it is for
7841 channel (library gets it from packet's Destination ID)).
7843 * Added silc_client_remove_from_channels into client library to
7844 remove a client from all channels it has joined to. Used when
7845 received SIGNOFF notify from server. Added also new function
7846 silc_client_replace_from_channels to replace old ID entry with
7847 new ID entry on all channels. Used when received NICK_CHANGE
7850 * Fixed ID Cache list handling in silc_idlist_get_client in
7851 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7852 to get (or query) client by ID.
7854 * Updated TODO list.
7856 * Added connection authentication status message defined by the
7857 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7858 support for these into the code in client and server side.
7860 * Added generic function silc_client_send_command to send any command
7861 with variable argument list. Application should use this function
7862 to send commands if the command functions provided by the library
7863 does not suite for the application's user interface needs.
7865 * Added new `failure' client operation. Application is notified about
7866 received failure packet if client is executing a protocol. In this
7867 case the protocol's execution has failed.
7869 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7870 is required by the protocol.
7872 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7873 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7876 * Added status flag to SilcSKE object to indicate realtime status
7877 of the SKE protocol.
7879 * Application receives now exactly same command reply arguments as
7880 the library receives from server. However, if ID is received the
7881 corresponding ID entry is returned to the application (eg. Client
7882 ID is mapped to correct SilcClientEntry entry and that is returned).
7883 Changed command_reply client operation due to this change.
7885 * Changed all ID's in commands and in command replys as ID Payloads.
7886 Change affected both client and server side codes.
7888 All ID's sent in SILC network (with execption of ID's in SILC
7889 Packet header) are sent in ID Payload to support variable length
7892 * Server now notifies nick changes and notifies all clients on
7893 the channels about the new nickname (about the new Client ID,
7896 * Implemented CMODE command to change channel modes. Supports all
7897 channel modes defined by the protocol specs except ban and invite
7898 lists. (Also, private channel key mode is supported but support for
7899 setting private channel key in client is missing, thus, this mode
7900 has no effect on client side (except that server requires that the
7901 client uses private channel key and normal channel traffic does not
7904 Also, invite mode works per se, but INVITE command does not work
7905 yet correctly, so you can set channel as invite only channel but
7906 inviting clients to the channel does not work (it is yet to be
7907 thought what's the best way to do it).
7909 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7910 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7911 Implemented CUMODE command to change user's mode on the channel.
7912 Supports all modes defined by the protocol specs.
7914 * Added NAMES command reply to return users modes on the channel.
7916 * Removed unnecessary and slow ciphers from lib/silccrypt.
7918 * Set SO_KEEPALIVE option to connection sockets by default.
7920 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7922 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7923 redefined the Notify Payload into protocol specs.
7925 * Added silc_id_payload_parse_id to get ID directly from raw
7928 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7930 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7931 accept searching by Client ID as well.
7933 * Added support for LEAVE and SIGNOFF notify types in client library.
7935 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7936 to parse ID Payload from raw data.
7938 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7940 * Added flags parameter into silc_ske_assemble_security_properties
7941 function in lib/silcske/silcske.[ch].
7943 * Changed notify client operation to fit better for notify messages
7944 sent by server. The notify payload received from server is now
7945 passed to the application (after parsing it to SilcNotifyPayload).
7946 It is application's responsibility to retrieve the arguments
7947 from the payload and show the message the way it wants. The message
7948 sent by server is implementation specific.
7950 * Changed public keys to comply with the protocol specification.
7951 Old public keys are not supported anymore and are not compatible.
7953 * Removed nickname from Channel Payload as the latest draft removed
7954 it. The client must resolve the nickname from the NAMES command
7955 reply received when it joined the channel.
7957 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7959 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7961 * Fixed some errors in protocol specification drafts.
7963 * Created lib/silccore/silcnotify.c to implement Notify Payload
7964 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7965 generic payloads described by protocol specifications. The file
7966 includes implementations for ID Payload and Argument Payload.
7968 * Changed Command Payload implementation to use the new Argument
7969 Payload. Changed command_xxxx_payload to command_payload_xxxx
7970 to comply with SILC coding conventions.
7972 * Added suppport for Argument Payload handling in Notify Payload
7973 implementation as protocol requires it. Added the new support
7974 into server and client lib as well.
7976 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7978 * Added support for multiple nicknames on same channel. [n] is
7979 added locally to the nickname if there are more than one same
7980 nicknames on the channel.
7982 * Server now sends all nicknames that matched WHOIS request.
7983 Client also shows the list received from server.
7985 * Added TOPIC command to client side. User can now set and show
7986 current topic on channel.
7988 * Added MOTD command to client and server. Also, server sends the
7989 motd when client connects to the server.
7991 * Changed version strings to comply ISO 8601.
7993 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7995 * Fixed protocol error handling in client library. It should now
7996 cope even if the SKE fails for some reason.
7998 * Made new protocol specification drafts for submitting to IETF.
8000 * Implemented TOPIC command to server in silcd/command.c.
8002 * Added two new notify types into lib/silccore/silcnotify.h:
8003 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
8004 notify nickname change and topic setting/change on a channel.
8006 * API change of command_reply operation in client library. The
8007 application gets now the status type received from server as well.
8009 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8011 * Removed the function just added to lib/silcutil/silcschedule.[ch].
8013 * Cras fixed and optimized the packet handling even further and
8014 it should work now. Minor change to the prototype of function
8015 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
8017 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8019 * Added new function into lib/silcutil/silcschedule.[ch]:
8020 silc_schedule_with_fd to select() a specified fd. The function
8021 returns after timeout expires or data arrives or goes. The
8022 function is used by packet routines to wait that all data is
8023 received from network.
8025 * Fixed data reading from network in lib/silccore/silcpacket.c.
8026 The code now assures that all data is read from the fd and then
8027 continues packet processing. This was a bug fix since the code
8028 used to drop some data in some circumstances.
8030 * Added new function into lib/silcclient/client.[ch]:
8031 silc_client_start_key_exchange to start key exchange after
8032 connection has been established to server. The code internally
8033 now uses this funtion but its main purpose was to provide it
8034 for applications that perform their own connecting. After
8035 application has created a connection it merely calls this
8036 function to start the key exchange between client and server.
8037 The library takes care of everything else after that.
8039 Updated also lib/silcclient/README to explain the usage of
8042 * Do not send to application information that connection has
8043 been established. Application gets notified it by connect
8046 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8048 * Applied cras's patch to add silc_schedule_one function. The
8049 function runs scheduler once and returns.
8051 * Fixed the scheduler after cras messed it up. The timeout
8052 handling works now as it's supposed to work.
8054 * Added into lib/silccore/ silcnotify.h to include notify
8055 message types support. Changed silc_server_send_notify*
8056 functions, in server.[ch], to support those new notify types.
8057 Added the support for the notify types into client library,
8058 as well. Added new notify client operation into ops.h in
8061 * Changed silc_server_packet_send_to_channel to send normal
8062 packets instead of just channel message packets. The function
8063 is now used to send the notify packets to channels. It is not
8064 used to send channel message packets anymore, as server never
8067 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
8068 va_arg()s as it seems to require it nowadays. I guess, if SILC
8069 is compiled with older va_arg() the new code should work anyway.
8071 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8073 * Splitted core library. Core library (lib/silccore) includes
8074 now only SILC protocol specific core (and common) components.
8075 Created new utility library (lib/silcutil) that includes more
8076 generic purpose stuff. The stuff for util library was taken
8077 from the old core library. This was minor and easy split.
8079 * Created SILC Client Library (lib/silcclient) that includes
8080 implementation of the SILC client without user interface. This
8081 was major move from silc/ directory. The code has been changed
8082 so that it is transparent towards the user interface. The
8083 silc/ directory includes now the same user interface as before
8084 and it uses the new client library. Read lib/silcclient/README.
8085 Basicly, the client library performs everything else related
8086 to SILC except user interface handling. Also, configuration
8087 files are considered to be part of user interface and library
8088 does not handle them.
8090 This change also changed a lot of structures, function naming etc.
8091 Most important change was that SilcClientWindow object was
8092 renamed to SilcClientConnection in the client library. Created
8093 also new file lib/silcclient/ops.h. Also added new files
8094 silc/local_command.[ch] and silc/client_ops.[ch].
8096 All these changes were made to make it easier for user interface
8097 designers to create what ever user interface for the SILC client
8100 It is also expected that the server will be moved to lib
8101 directory as well and SILC Server Library will be created;
8102 sometimes in the future.
8104 * Removed Local commands from lib/silccore/silccommand.h as
8105 they are application specific and new client library does not
8106 handle any of those anymore.
8108 * Several functions moved to lib/silcutil/silcutilc.[ch] from
8109 old client implementation in silc/.
8111 * Added support for callback functions in SILC_LOG_* macros.
8112 Application can now set its own callbacks that will be called
8113 instead of using the default functions that will always print
8114 the debug messages to stderr (or stdout). Also, debugging can
8115 now be disabled by setting silc_debug to FALSE and re-enabled by
8116 setting it to TRUE. Note, that logging will still work even
8117 if debugging is disabled.
8119 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
8120 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
8121 silc_log_reset_debug_callbacks.
8123 * To enable debugging in silc client one must give now -d
8124 option on command line.
8126 * Changed silc_schedule_init to automatically allocate task queues
8127 if they are not allocated before calling it.
8129 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8131 * Added GMP 3.1 into math library.
8133 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8135 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
8136 a channel in SILC network. The packet is used by servers and
8137 routers to notify other routers that user has left a channel.
8138 This little feature was missing until now. Added the feature
8139 to protocol specification as well.
8141 Added functions: silc_server_send_remove_channel_user and
8142 silc_server_remove_channel_user into server.[ch].
8144 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
8145 lib/silccore/silcpacket.h. However, they are not implemented
8148 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8150 * Fixed joining to a channel and sending channel messages
8151 between server and router. The channel message sending should
8152 now work inside a cell.
8154 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8156 * Fixed the private message sending between server and router.
8157 The private message sending should now work inside a cell.
8159 * Added silc_server_replace_id into server.[ch] to replace
8160 existing ID in the SILC network.
8162 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
8163 and silc_idlist_replace_server_id into idlist.[ch] in server.
8165 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8167 * Fixed the server to server connections. Server can again now
8168 connect to router. Router to router connections probably does
8171 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8173 * Added dynamic protocol registering support. Now protocols can
8174 registered and unregistered on the fly. Patch by cras.
8176 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8178 * Added lib/contrib directory to hold routines that some platforms
8179 don't have but are needed by SILC.
8181 * Added getopt.c, getopt1.c and getopt.h from GNU C library
8182 into lin/contrib to provide getopt() and getopt_long() for
8183 those who don't have it.
8185 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8187 * Added AWAY command to client. When away message is set and
8188 client receives a private message packet the client automatically
8189 replies to the sender with the away message.
8191 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
8192 bug seemed to be the cause of recent problems when compiling
8195 * Added version detection support to SKE protocol specification
8196 and added the new changes to the SKE implementation as well.
8197 There were other minor changes in the SKE protocol as well.
8199 Many changes in lib/silcske/silcske.[ch] and in
8200 lib/silcske/payload.[ch].
8202 * Added ^U functionality, clear input line. Patch from cras.
8204 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8206 * Mainly small bugfixes on core library. Fixed some debugging
8207 logging and buffer overflow in silclog.c.
8209 * Updated config.sub and config.guess on the distribution tree.
8211 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8213 * Added command lagging support in server. Client may execute
8214 commands now only once in two seconds.
8216 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8218 * Optimized packet reception. MAC computation and checking is now
8219 also more optimized. A lot previously duplicated code is now
8220 used as generic by both client and server.
8222 * Fixed key pair generation in clientutil.c
8224 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8226 * Added into lib/silccore/silcbufutil.[ch] new function;
8227 silc_buffer_realloc.
8229 * Moved generic packet sending/encryption functions to
8230 lib/silccore/silcpacket.[ch] from client and server. Some
8231 rewriting of the functions.
8233 * Moved all generic packet reception/decryption functions to
8234 lib/silccore/silcpacket.[ch] from client and server. The
8235 packet processing is now much cleaner in both client and server.
8236 These were major changes in both client and server.
8238 * Created many common functions in server to do packet sending.
8239 Previously code were duplicated a lot, this has been removed
8242 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8244 * Rewrote major parts of the ID cache system. Don't know
8245 whether it is better now or not but at least the API is more
8248 * Major rewrite on ID cache stuff on client because of the ID
8249 cache API changes. Added idlist.c to client.
8251 * Also major rewrite on ID cache stuff on server as well.
8252 Major rewrite of idlist.[ch]. SilcXXXList's are now named
8253 SilcXXXEntry's. We won't keep anymore idlist specific pointers
8254 in hand, instead they are all put into the ID cache system now.
8255 All server_idlist_* routines uses ID cache now instead of
8256 traversing its own lists (those lists does not exist anymore).
8257 SilcIDList though still exists. Also, SilcXXXEntry's are
8260 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8262 * Finally made the SKE implementation compliant to the protocol
8263 specification. All mp integers are now binary encoded as
8264 opposed being HEX encoded.
8266 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
8269 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
8270 functions: silc_[encode/decode]_pem. Also added function
8271 silc_encode_pem_file to PEM encode with newlines ('\n') for
8274 * SILC public keys are now encoded either PEM or binary. Same
8275 option is for private keys as well. By default private keys
8276 are binary encoded and public keys PEM encoded. Silly HEX
8277 encoding were removed.
8279 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
8280 function to create fingerprints.
8282 * Fixed a bug in SHA1; does not change the original data anymore.
8284 * Partly implemented INFO command on client and server side.
8285 Fixed CLEAR command. Changes to SERVER command; show current
8286 server(s) when giving command without arguments. Added
8287 VERSION command to client.
8289 * Added check to server that unregistered connections cannot
8290 execute commands (unless it is specificly allowed).
8292 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8294 * Fixed screen refresh.
8296 * Fixed channel joining bug from client. On some circumstances
8297 client tried to join to a channel it had already joined.
8299 * Added public key verification process into client's protocol.c.
8300 The client now verifies the public key from user and saves
8301 it into ~./silc/serverkeys/ directory.
8303 Added into: clientutil.[ch]: silc_client_verify_server_key.
8305 * Changed SKE protocol's silc_ske_initiator_finish function
8306 to accept callback function that verifies the received public
8307 key. Removed old silc_ske_verify_public_key function.
8309 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8311 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
8312 silc_pkcs_private_key[_data]_set.
8314 * Made the password and public authentication more cleaner in
8315 server's protocol.c.
8317 * Removed historic and obsolete protocol `channel_auth' from
8318 both client and server.
8320 * Removed wrong way of sending command status messages from
8321 server to client in server's command.c. The old way violated
8322 protocol specification.
8324 Changes to silccore/silccommand.[ch]: removed
8325 silc_command_encode_status_payload -> not needed anymore,
8326 changed silc_command_encode_payload_va to accept extra
8327 argument on variable argument list. The argument type must
8328 now be provided to the function. Also, added new function:
8329 silc_command_encode_reply_payload_va which is same as
8330 normal command_encode_payload_va except command status type
8331 is provided as extra argument.
8333 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8335 * Added ~./silc directory handling. The directory includes the
8336 public and private keys for the client.
8338 Added silc_client_check_silc_dir, silc_client_create_identifier
8339 and silc_client_load_keys.
8341 * Implemented SILC protocol compliant public key. Added public
8342 and private key saving to and loading from files.
8344 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
8345 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
8346 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
8347 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
8348 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
8350 Implemented: silc_pkcs_save_[public/private]_key[_data] and
8351 silc_pkcs_load_[public/private]_key.
8353 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8355 * Added silc_server_get_route (route.[ch]) to get connection
8356 data for the fastest route for given ID.
8358 * Implemented INVITE command on client and server. The command
8359 were re-defined in the SILC Protocol Specification and the
8360 implementation now complies with the specification.
8362 * Implemented PING command on client and server.
8364 * Implemented NAMES command on client and server. The server side
8365 supports currently only normal server not router server yet.
8366 Some changes to NAMES definition in SILC protocol specification.
8368 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8370 * Implemented LEAVE command on client and server.
8372 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
8373 again. This change was made to the protocol as well. Server
8374 should not violate the protocol specification anymore.
8376 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8378 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
8379 was tested. SOCKS4 was not but should work anyway.
