511 lib/silcclient/client_prvmsg, lib/silcclient/client_channel.c,
512 lib/silcclient/silcclient.h, irssi/src/silc/core/client_ops.c,
513 and lib/silcclient/client_ops_example.c.
515 * Added two new channel modes: SILC_CMODE_SILENCE_USERS
516 and SILC_CMODE_SILENCE_OPERS which can be used to moderate
517 the channel. Updated protocol specs and impelemented this
518 to client and server. Protocol TODO #6. Affected files are
519 silcd/packet_receive.c, server_util.c, lib/silcclient/command.c,
520 lib/silcclient/client_channel.c, lib/silccore/silcmode.h.
522 Added new options m and M to CMODE command in Irssi SILC
523 client to set these modes.
525 * Deprecated all administrative commands from SILC protocol
526 since they are highly implementation specific commands.
527 Updated protocol specs. Moved the old commands in
528 implementations to private range of command types. Affected
529 files are silcd/command.c, lib/silcclient/command.c and
530 lib/silcclient/command_reply.c. Protocol TODO #8.
532 * Fixed a bug in server where sending unknown command crashes
533 the server. Affected file silcd/command.c.
535 Wed Apr 3 09:57:47 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
537 * Added SILC_PROTOCOLVERSION macro to check protocol version
538 of a socket connection. The affected file is
539 lib/silcutil/silcsockconn.h.
541 * Added better error logging in rekey protocol. Affected file
544 * Do not check public key types in SKE during rekey. Affected
545 file lib/silcske/payload.c.
547 * Fixed the rekey protocol with PFS, which was totally broken.
548 Affected file silcd/protocol.c.
550 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
552 * Some client implementations quit network by doing first LEAVE
553 and then immediately SIGNOFF (like Bombyx). We now do check
554 after a short time after LEAVE notify and check whether the
555 client is still valid after LEAVE, and if not we remove it from
556 cache. Affected file is lib/silcclient/client_notify.c.
558 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
560 * Merged version 1.1.4 of zlib. Even if it not currently in use,
561 it's good not to have security holes here.
563 * Fixed a negative refcount situtuation for the config context.
564 Affected file is silcd/serverconfig.c.
566 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
568 * ROBOdoc documented lib/silcutil/silcutil.h.
570 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
572 * Optimized even more the SilcPacketContext structure. Now
573 totally saved 16 bytes of memory per context after optimization.
574 Affected files are lib/silccore/silcpacket.[ch].
576 * Made strict checks for valid SILC IDs. Affected file is
577 lib/silccore/silcid.c.
579 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
581 * Changed the object argument for silc_cipher_register,
582 silc_hash_register, silc_hmac_register and silc_pkcs_register
583 to const. Affected files are lib/silccrypt/silccipher.[ch],
584 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
586 * Changed the silc_get_username and silc_get_real_name to
587 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
589 * Fixed the Irssi SILC Client to use the silc_get_username and
590 silc_get_real_name insted of glib routines since the glib
591 routines only corrupt stack. Fixes the Irssi SILC to work in
592 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
594 * Fixed the Irssi to not use g_get_home_dir since it crashes
595 or returns garbage on cygwin and corrupts stack. Added function
596 get_home_dir to Irssi routines. Affected files are
597 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
599 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
601 * Made some structure optimizations. SFTP memory FS MemFSEntry
602 entry structure. Optimized SilcTask structure. Optimized
603 SilcPacketContext structure.
605 Affected files lib/silcsftp/sftp_fs_memory.c,
606 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
608 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
610 * And yet again reverted back the config thing since Johnny
611 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
614 * Fixed memory leaks from config object. Affected files are
615 silcd/serverconfig.[ch].
617 * Added support for adding new connections to the server in rehash.
618 After rehash they take effect.
620 Added support for changing the maximum allowed connections in
621 rehash. The number can grow but going smaller is not supported.
623 Added function silc_server_num_sockets_by_remote to the
624 silcd/server_util.[ch].
626 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
628 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
630 * Added preliminary checking during config parsing for a valid
631 public/private key and removed further checks in the code.
632 Affected files are silcd/serverconfig.[ch], server.c.
634 * Moved functions silc_server_drop() and silc_server_daemonise()
635 from server.c to silcd.c since they are stricly related to
636 the application activity.
638 * Reverted a small part of the automatic ref/unref since
639 it caused a double unref in some situations. Affected
640 files are silcd/silcd.[ch], server.c, serverconfig.c.
642 * Added some .cvsignore files in the lib directory.
644 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
646 * Fixed silc_net_gethostbyaddr to correctly resolve by
647 address. Affected file lib/silcutil/silcnet.c.
649 * Fixed the notify relaying to client. The HMAC to be used
650 with relayed packets ws wrong and caused decryption failure
651 at the client end. Affected file is silcd/packet_receive.c.
653 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
655 * Created new branch silc_protocol_1_0_branch.
657 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
659 * Changed the silc_server_config_* routines to be SilcServer
660 independent. They are now officially application specific code
661 and not part of generic server implementation. Affected files
662 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
664 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
666 * Added automatic referencing of config context in the
667 silc_server_config_alloc, and automatic unreferencing in the
668 silc_server_config_destroy. Affected files are
669 silcd/serverconfig.[ch], silcd/silcd.c.
671 * Fixed the silc_log_quick handling in the logging routines.
672 It didn't log quickly when it was TRUE. Affected file is
673 lib/silcutil/silclog.c. Also the flush delay was set even
674 if it was 0 in config file. Affected file is
675 silcd/serverconfig.c.
677 * Added support for changing key pair of the server in rehash.
678 Affected file silcd/server.c.
680 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
682 * Fixed the TOPIC_SET notify to not cras. It changed the topic
683 too early, before getting the channel entry. Affected file
684 is silcd/packet_receive.c.
686 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
688 * Added functions silc_server_config_[ref/unref], these are used
689 to prevent that the config object is destroyed.
691 No longer directly affect global variables silc_log_quick and
692 silc_log_delay, they are first cached inside the config object
693 and then applied with silc_server_config_setlogfiles().
695 silc_server_config_set_defaults() is now internal to
696 serverconfig.c, there are no reasons to show this internal stuff
699 Affected files are silcd/serverconfig.[ch].
701 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
702 fprintf's to stderr, since some code may be executed again after
703 the server went into the background. Affected files are
706 * Added rehash support. Added function silc_server_rehash() that
707 will perform all the basic tasks of the rehashing procedure.
709 * Added command line option `-x, --hexdump'. This will enable the
710 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
711 The option `--hexdump' implies `--debug'.
713 * Fixed a bad bug in the logging APIs (silcutil library) where
714 the application would crash after calling silc_log_reset_all().
716 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
718 * Fixed the KICKED notify handling in client library to
719 correctly remove the channel and all entries from the
720 channel when I was kicked. This bug crashed the client.
722 Fixed yet another but in KICKED notify handling to remove
723 the kicked client correctly from the channel.
725 Affected file is lib/silcclient/client_notify.c.
727 * Fixed a minor bug in looking up correct client entry
728 in KICKED notify in server. Affected file is
729 silcd/packet_receive.c.
731 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
732 sources correctly to distribution. Fixes --with-gmp option.
734 * Removed the manual rehashing from ID Cache, and changed it
735 to use the SILC Hash Table's auto rehash feature. Affected
736 file is lib/silccore/silcidcache.c.
738 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
740 * Fixed a bug in the silc_client_nickname_format function that
741 handles the multiple same nickname formatting. Two clients
742 with same nickname caused problems after the first one left
743 and rejoined. It didn't format the nickname correctly.
744 Affected file is lib/silcclient/idlist.c.
746 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
748 * Don't change the topic if olod topic is same as new one.
749 Affected file is silcd/packet_receive.c.
751 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
753 * Added cross-reference support to the SILC Documentation
754 generator. All types across all HTML files are now cross-
755 referenced. Affected files util/robodoc/generator.c and
756 scripts/silcdoc/silcdoc.
758 * Added file lib/silcutil/silctypes.h to include all the
759 arithmetic type definitions and some macros. Removed
760 includes/bitmove.h and moved macros to silctypes.h.
762 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
764 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
766 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
768 * Added `type' argument to silc_id_payload_parse_id function which
769 now returns the type of the ID to the sent pointer. Affected
770 file is lib/silccore/silcid.[ch].
772 * Added check for CMODE_CHANGE notify type that mode change is
773 allowed by the sender. Affected file silcd/packet_receive.c.
775 * Added check for CUMODE_CHANGE notify type that mode change is
776 allowed by the sender. Affected file silcd/packet_receive.c.
777 Added the ID type as CUMODE_CHANGE notify type as argument
778 to the `notify' client operation. Affected files are
779 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
781 * Added function silc_client_add_server to the client library.
782 Added support for resolving also channel and server info when
783 received unknown entity in notify packet. Affected files are
784 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
786 * Added function silc_command_get_status to return the command
787 status from the command reply's argument payload. Affected files
788 are lib/silccore/silccommand.[ch].
790 * Added check for KICKED notify type that the kicking is
791 allowed by the client. Affected file silcd/packet_receive.c.
793 * Created function silc_get_input which can be used to get input
794 (echo on or off) from user on command line. Affected files are
795 lib/silcutil/silcutil.[ch].
797 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
799 * Optimized silc_server_packet_relay_to_channel function.
800 Added new function silc_channel_message_payload_encrypt which
801 can be called directly if channel message payload needs to
802 be encrypted and is already encoded (no need to call _encode
803 function). Packet relaying is now done by router without any
804 extra memory allocations. Affected files are
805 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
808 * Fixed the INVITE notify handling. It took wrong arguments
809 as invite list and invite delete. Affected file is
810 silcd/packet_receive.c.
812 * Added check for TOPIC_SET notify type that the topic change is
813 allowed by the client. Affected file silcd/packet_receive.c.
815 * Added check for INVITE notify type that inviting is allowed by
816 the client. Affected file silcd/packet_receive.c.
818 * Changed the silc_server_client_on_channel to return the
819 SilcChannelClientEntry as well. Moved the function
820 silc_server_check_cmode_rights to server_util.[ch].
821 Affected files are silcd/server_util.[ch], silcd/command.c.
823 * Added function silc_server_check_umode_rights to check whether
824 changing client's user mode is allowed. Added check for
825 UMODE_CHANGE notify type that the umode change is allowed
826 by the client. Affected files are silcd/server_util.[ch],
827 silcd/packet_receive.c and silcd/command.c.
829 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
831 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
832 ID length. It ignored that ID can be IPv6 based as well.
833 Affected file lib/silccore/silcpacket.h.
835 * Fixed the silc_id_id2str and silc_id_str2id to take the
836 IPv6 address offset's into consideration. Affecte file is
837 lib/silccore/silcid.c.
839 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
841 * Fixed the internal Unix scheduler functions to check for
842 NULL context they may receive. The affected file is
843 lib/silcutil/unix/silcunixschedule.c.
845 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
847 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
848 can specify different directory with --home command line
849 parameter. Affected files irssi/src/silc/core/client_ops.c,
852 * SILC-specific commands aren't now executed if the active server
853 isn't of SILC-type, so there won't be problems with having
854 IRC and SILC protocol support in same client. Affected files
855 irssi/src/silc/core/silc-channels.c, silc-servers.c,
858 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
860 * Improved the signal support in SILC Schedule. Added new
861 function silc_schedule_signal_call which is used by application
862 to mark a signal to be called. It is now safe to perform
863 any kind of tasks in signal callbacks since it is guaranteed
864 that the application specified signal callback is called
865 after the signal is over. Affected files are
866 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
868 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
870 * Added `name' field to SilcChannelPrivateKey to represent
871 application given name for the key. Moved also the context from
872 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
873 Added the `name' argument also to the function
874 silc_client_add_channel_private_key.
876 Added function silc_client_current_channel_private_key to set the
877 current channel private key in use.
879 Added "change" command to KEY command which can be used to change
880 the current channel private key. Bound the command also to
883 Also affected files lib/silcclient/client_channel.c,
884 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
886 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
888 * Added silc_rng_get_byte_fast function in to the
889 lib/silccrypt/silcrng.[ch].
891 * Changed the interface of silc_packet_assemble and the
892 silc_packet_send_prepare. If silc_packet_assmble is now
893 called the application does not call silc_packet_send_prepare
894 because the library will call it automatically. These
895 interfaces now also return a reference to the outgoing buffer
896 which includes the assembled packet, which the application can
897 use to encrypt the packet.
899 Affected files are lib/silccore/silcpacket.[ch],
900 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
901 silcd/packet_send.c, server_backup.c and packet_receive.c.
903 * Fixed a packet sending bug on very high load, where outgoing
904 packet queue wasn't handled correctly and packets got corrupted.
905 Affected files are lib/silcutil/*/silc*sockconn.c,
906 lib/silcclient/client.c and silcd/server.c.
908 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
910 * Added macro SILC_PACKET_DATALEN which can be used during
911 packet assembling to check whether the data to be added to
912 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
913 len is truncated until it fits it.
915 Added checks for maximum length of channel message payload and
916 private message payload also.
918 Added checks for maximum packet length in server and in
921 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
922 lib/silcclient/client.c, lib/silccore/silcchannel.c and
923 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
924 lib/silcclient/client_prvmsg.c.
926 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
928 * Added silc_server_packet_queue_purge call to the
929 silc_server_disconnect_remote to assure that all data in the
930 queue before disconnecting is sent to the network. Affected
933 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
935 * Added the deleting of server's own ID cache entry to the
936 silc_server_free function. Free also everything else that
937 has been allocated in silc_server_init. The affected file
940 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
942 * Added functions silc_parse_version_string, silc_version_to_num,
943 and silc_ske_parse_version to parse SILC protocol style version
944 strings. Affected files lib/silcutil/silcutil.[ch] and
945 lib/silcske/silcske.[ch].
947 * Added new configuration params: version_protocol, version_software
948 and version_software_vendor to specify what version the remote
949 host must at least be to be able to connect to server. The vendor
950 string can be regex matched too. Added new function
951 silc_server_connection_allowed to check maximum number of allowed
952 connections, and allowed versions for incoming connections.
953 Affected files are silcd/server.c, server_util.[ch] and
956 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
958 * Added preliminary support for signals in scheduler. The
959 signals we care about are now blocked always when the scheduler
960 is locked. This way we can synchronise the use of signal with
961 scheduler. It is guaranteed that when signal occurs the scheduler
962 is not locked, and thus new tasks can be safely added to the
965 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
966 to silc_schedule_internal_init and silc_schedule_internal_uninit.
967 Added new platform specific routines
968 silc_schedule_internal_signals_[un]block and
969 silc_schedule_internal_signal_[un]register.
971 Added new functions to SILC Schedule API:
972 silc_schedule_signal_[un]register. Each signal that application
973 is going to use should be registered to the scheduler.
975 Affected files are lib/silcutil/silcschedule.[ch],
976 lib/silcutil/*/silc*schedule.c.
978 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
980 * Check for unauthenticated client and server in the
981 silc_server_new_client and silc_server_new_server functions.
982 Affected file silcd/packet_receive.c.
984 * Added function silc_string_is_ascii to check whether given
985 string is 7-bit ASCII string. Affected files are
986 lib/silcutil/silcutil.[ch].
988 * Added function silc_id_is_valid_server_id into the
989 silcd/serverid.c and added checking for valid Server ID's in
990 silc_server_new_server. The Server ID must always be based
991 on the server's public IP address.
993 * Added logging of DISCONNECT packet message in the server.
994 Affected file silcd/server.c.
996 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
998 * Changed all library interfaces that use Global RNG to also
999 accept SilcRng as argument. Affected files are
1000 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
1001 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
1002 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
1003 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
1004 lib/silccrypt/rsa.c.
1006 * Added function silc_pkcs_generate_key to the
1007 lib/silccrypt/silcpkcs.[ch] for applications so that they
1008 don't need to do pkcs->pkcs->init calls anymore.
1010 * Remove SilcSocketConnection from the SFTP API since it really
1011 wasn't needed there. The application has the information
1012 saved in its contexts anyway and the SFTP layer doesn't need
1013 know about it. Affected files lib/silcsft/silcsftp.h and
1014 lib/silcsftp/sftp_[server/client].c.
1016 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
1017 The SilcSimContext is not SilcSim.
1019 * Fixed possible buffer overflows in silc_id_render in the
1020 lib/silcutil/silcutil.c.
1022 * On EPOC the global crypto module lists are not used at all
1023 in the crypto library. Added support for using the constant
1024 algorithm list on EPOC. Affected files are
1025 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
1028 * Fixed the handling of third parameter of KICKED notify, since
1029 it was mistakenly updated to SILC Protocol 1.0 even though it
1030 is to be included in 1.1. Since it is not in 1.0 it is not
1031 mandatory, and this fix now handles it only if it is provided,
1032 and it is not error if it is not provided. Affected file

1072 file lib/silcutil/silcutil.[ch].
1074 * Added support for specifying multiple public keys for Client
1075 connection section in server configuration file. This makes it
1076 possible to accept multiple public keys from same host, or to
1077 make a section that accepts any incoming host, and have the
1078 accepted public keys listed in the section.
1080 Added functions silc_sever_[find/get]_public_key, added the
1081 support for this actually to all connection sections but only

1190 includes/silcincludes.h.
1192 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
1193 old name went against naming convention. Applications now
1194 include "silcclient.h" instead of "clientlibincludes.h".
1195 Removed includes/clientlibincludes.h, it is redundant now.
1197 * Renamed includes/version.h to silcversion.h.
1199 * Added really preliminary support for OS/2 into the util
1200 library. Only thread & mutex API is implemented, others
1201 are still to be implemented. Created the lib/silcutil/os2/

1235 * Added `user_count' to the SilcChannelEntry which now tells the
1236 number of users on the channel. The user count is now saved
1237 in normal server of global channels as well. Affected files
1238 silcd/server.c, idlist.h, packet_receive.c and command.c.
1240 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
1241 include file utility functions.

1256 * ROBOdoc documented the lib/silcske/silcske.h, and improved
1257 the SKE interface a bit.
1259 * Fixed padding problem in PKCS#1. The padding was not actually
1260 random since the random number generator was used incorrectly.
1261 This security bug affects only when encrypting with PKCS#1, and
1262 it is not currently used at all in SILC. SILC only use signing
1263 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
1265 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1323 is now done in silc_core_init() which also fixes autoconnecting
1326 Affected files irssi/src/silc/core/silc-core.c,
1327 irssi/src/fe-text/silc.c.
1329 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1331 * Added new configuration options and blocks:
1332 keepalive_secs, reconnect_count, reconnect_interval,
1333 reconnect_interval_max, reconnect_keep_trying and
1334 require_reverser_lookup. Added ConnectionParam block, and
1335 implemented the connection parameters when connecting as
1336 initiator and when accepting connections as responder.

1348 the connection configuration object from the SilcServerConnection
1349 object instead of finding it during the connecting phase.
1350 Added the configuration object to SilcServerConnection struct.
1351 Affected files silcd/server_internal.h, server.c.
1353 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1355 * Add the client on channel after it was resolved at the
1356 channel message receiving, and it was not already on the
1357 channel. Affected file lib/silcclient/client_channel.c.
1359 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1375 authentication to be set at the same time.
1377 Added `prefer_passphrase_auth' setting in config file which
1378 can be used to set to prefer passwd auth if both passwd and
1379 public key is set. If not set, public key is preferred.
1380 This has effect only when being initiator (responder will try
1383 Added support for authentication with passphrase and public key
1384 at the same time. The passphrase is tried first always since
1385 it is faster to check.
1387 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
1389 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

1435 * Fixed the file transfer's key agreement payload to include
1436 zero port also if the hostname is NULL because it could not
1439 Call file transfer monitor callback now also if error occurs
1440 during key agreement protocol.
1442 Changed the silc_client_file_send interface to return the
1443 SilcClientFileError instead of session id. The session ID
1444 is returned into pointer provided as argument.

1461 file lib/silcutil/silclog.c.
1463 * Fixed the channel message payload decryption in the function
1464 silc_channel_message_payload_decrypt to not modify the original
1465 buffer before it is verified that the message decrypted
1466 correctly. Otherwise, next time it is called with correct
1467 channel key it won't encrypt since the payload is corrupted.
1468 Affected file lib/silccore/silcchannel.c.
1470 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1482 * Fixed a bug in hash table internal routine for traversing
1483 the table with foreach callback. The current entry may
1484 become invalid in the callback but it was referenced after
1485 the callback returned.
1487 Do not allow auto rehashing of hash table during the
1488 silc_hash_table_foreach operation, for same reasons as it is
1489 not allowed for SilcHashTableList. Affected files are
1490 lib/silcutil/silchashtable.[ch].
1492 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>

1513 users list to SilcHashTable. The affected files are
1514 lib/silcclient/idlist.[ch].
1516 * Fixed a bug in hash table tarversing. While the hash table
1517 is traversed with SilcHashTableList the table must not be
1518 rehashed. It is now guaranteed that auto rehashable tables
1519 are not rehashed while tarversing the list. Also defined that
1520 silc_hash_table_rehash must not be called while tarversing
1521 the table. Added function silc_hash_table_list_reset that must
1522 be called after the tarversing is over. The affected files are
1523 lib/silcutil/silchashtable.[ch].
1525 * Changed all hash table traversing to call the new
1526 silc_hash_table_list_reset in server and in client library.
1528 * Added function silc_client_on_channel to return the
1529 SilcChannelUser entry if the specified client entry is joined
1530 on the specified channel. This is exported to application as
1531 well. Affected files lib/silcclient/client_channel.c, silcapi.h.

1536 server. The notify for mode change must be sent always and
1537 not only if !cmd->pending. Affected file silcd/command.c.
1539 * Fixed the WHOWAS command's reply sending to support the
1540 lists correctly. Affected file silcd/command.c.
1542 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1544 * When sending JOIN command to router for processing the
1545 sender's old command identifier was not saved back to the
1546 sender's command context, fixed now. The affected file is
1549 * Create the key in JOIN command of the router did not return
1550 the channel key, added check for this. Affected file is
1553 * Fixed a channel ID update bug in JOIN command reply. Do
1554 not directly upgrade the ID but call the function
1555 silc_idlist_replace_channel_id if the ID was changed.
1556 Affected file silcd/command_reply.c.
1558 * Fixed memory leaks from command calling if it would fail.
1559 Affected file silcd/command.c.
1561 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1563 * Applied patches from cras:
1565 Memory leak fixes around libaries, irssi window resize fix,
1566 new silclist.h and silcdlist.h, all extern inline changed to
1569 * Removed dotconf from lib/dotconf, not needed anymore.
1571 * Removed TRQ from lib/trq, not needed anymore.
1573 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
1574 with server connections. Later this will be configurable
1575 in config file after new config file is done. Affected file
1578 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1580 * Fixed a crash in server related to channel announcements.
1581 Affected file silcd/server.c.
1583 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1585 * Fixed memory leaks in silc_server_create_new_channel*
1586 functions. Affected file silcd/server.c.
1588 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
1589 which ID was changed. This way the router will send the
1590 user list for the channel again, and server won't be in
1591 desync in some rare circumstances. Affected file is
1592 silcd/packet_receive.c.
1594 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1596 * Check for NULL socket pointer in the function
1597 silc_server_packet_send_to_channel_real. Affected file
1598 silcd/packet_send.c.
1600 * Fixed the BAN notify handling to correctly remove ban
1601 list. Affected file silcd/packet_receive.c.
1603 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1605 * Fixed some header addition to Toolkit distribution in
1606 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
1608 * Added lib/silcclient/client_ops_example.h as an template
1609 file for application programmers to quickly start using
1610 the SilcClientOperation functions in their application.
1611 Updated the lib/silcclient/README as well to tell about this
1612 nice file made available.
1614 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1616 * Call silc_server_remove_from_channels when removing client
1617 entry when NO_SUCH_CLIENT_ID was received. Affected file
1618 is silcd/command_reply.c.
1620 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1622 * Added server & router operator statistics updating. Affected
1623 file silcd/packet_receive.c and silcd/command.c.
1625 * Fixed the SERVER_SIGNOFF notify handling on normal server
1626 not to save the history information for clients. Same was
1627 fixed earlier in remove_clients_by_server function, but not
1628 here. Affected file silcd/packet_receive.c.
1630 * Raised the default connection-retry count from 4 to 7 in
1631 server. Affected file silcd/server.h.
1633 * Cancel any possible reconnect timeouts when we start the
1634 key exchange. Affected file silcd/server.c.
1636 * Do not reconnect on connection failure when SCONNECT was
1637 given. Affected files silcd/server.[ch].
1639 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1641 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
1643 * Fixed the NICK command to always give the unformatted
1644 nickname to the one giving the NICK command. If unformatted
1645 nickname is cached already it will be formatted and the
1646 local entry will always get the unformatted nickname.
1647 Affected file lib/silcclient/idlist.c.
1649 * Fixed some double frees from client library commands.
1650 Affected file is lib/silcclient/command.c.
1652 * Fixed CUMODE command in server to assure that no one can
1653 change founder's mode than the founder itself, there was a
1654 little bug. Affected file silcd/command.c.
1656 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1658 * Removed the SilcClientCommandDestructor from the client
1659 libary, it is not needed anymore. Affected files are
1660 lib/silcclient/silcapi.h, command[_reply].[ch],
1661 client_notify, idlist.c.
1663 * Fixed GETKEY command to first resolve client, and then
1664 resolve the server only if the client was not found, instead
1665 of resolving both at the same time. Affected file is
1666 lib/silcclient/command.c.
1668 * Added silc_client_start_key_exchange_cb and lookup the
1669 remote hostname and IP address before starting the key
1670 exchange with server. The affected file is
1671 lib/silcclient/client.c.
1673 * The server's public key is now saved using the IP address
1674 of the server and not the servername for the filename.
1675 The hostname public key filename is checked as an fall back
1676 method if the IP address based filename is not found.
1678 Fixed the GETKEY command to save the fetched server key
1679 in correct filename.
1681 Print the remote server's hostname now when new key is
1682 received during connection process. Affected file is
1683 irssi/src/silc/core/client_ops.c.
1685 * Return always our own public key to the client if it asks
1686 for it with GETKEY command. Affected file silcd/command.c.
1688 * Removed the use_auto_addr variable from default config
1689 file since it was in wrong section. Affected file is
1692 * Fixed TOPIC_CHANGE notification to not route it when it
1693 was sent using silc_server_send_notify_to_channel function.
1694 Affected file silcd/command.c.
1696 * Fixed silc_server_send_notify_kicked to send the kicker's
1697 Client ID also, it was missing. Affected files are
1698 silcd/command.c, silcd/packet_send.[ch].
1700 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1702 * Do not save client history information in SERVER_SIGNOFF.
1703 Fixes the bug in normal server that it does not detect
1704 the client becoming valid after the server becomes back
1705 online. Affected file silcd/server_util.c.
1707 * Added `sock_error' field into the SilcSocketConnection
1708 context. When error occurs during socket operation (read
1709 or write) the error is saved. Added also new function
1710 silc_socket_get_error to return human readable socket error
1711 message. Affected files are lib/silcutil/silcsockconn.[ch],
1712 lib/silcutil/unix/silcunixsockconn.c, and
1713 lib/silcutil/win32/silcwin32sockconn.c.
1715 * The server now prints the socket error message in the
1716 signoff for client. Affected file silcd/server.c.
1718 * Fixed the `created' channel information sending from router
1719 to server in JOIN command. Checks now whether the channel
1720 really was created or not and set it according that.
1722 Fixed the JOIN command to use the client entry's current
1723 ID during the joining procedure instead of the one it sent
1724 in the command (it is checked though), since it can change
1725 between the packet processing and command processing, and
1726 would just case unnecessary pain in the client end. Affected
1727 file silcd/command.c.
1729 * Fixed a channel key payload sending to use correct channel
1730 ID when the server was forced to change the channel's ID by
1731 router. Router sent the key payload with the old Channel ID.
1732 Affected file silcd/packet_receive.c.
1734 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1736 * Call silc_server_save_channel_key only if the key payload
1737 was provided in the JOIN command's command reply. Affected
1738 file silcd/command_reply.c.
1740 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1742 * Fixed silc_mp_sizeinbase to return the value correctly with
1743 MPI. Affected file lib/silcmath/mp_mpi.c.
1745 * Fixed the stop_server signal to correctly stop the scheduler
1746 and gracefully stop the server when SIGTERM or SIGINT signals
1747 are received. Affected file silcd/silcd.c.
1749 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1751 * Simple handling of TERM and HUP signals. Also added some log
1752 flushing call around. Affected file is
1755 * Fixed small bugs in silclog.c. Now buffering output will take
1756 effect after 10 seconds since startup: This will ensure that
1757 no important startup messages are lost. Also output redirection
1758 will preserve original format ([Date] [Type] message).
1759 Affected file is lib/silcutil/silclog.c.
1761 * Added two options to the config file, in the logging section:
1762 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1763 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1765 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1767 * Do not print the warning about log files not being initialized
1768 more than once to avoid excess logging. Affected file is
1769 lib/silcutil/silclog.c.
1771 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1772 the SIM copying in make install in Makefile.am.pre.
1774 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1776 * Rewritten silclog APIs. Globally interesting changes follows:
1777 silc_log_set_files() changed to silc_log_set_file().
1778 silc_log_set_callbacks() changed to silc_log_set_callback().
1779 ROBOdoc documented silclog header file.
1780 SilcLogCb now returns bool to wether inihibit the default
1781 handler or not (to keep the old behaviour return always TRUE).
1782 The new APIs should also fix the problem of the
1783 silcd_error.log file that was written in the current directory.
1786 Log files streams will remain opened after silc_log_set_file()
1787 call, means less CPU usage notably on high traffic servers.
1788 File streams are now full buffered, and flushed to the disk
1789 every 5 minutes, lesses HD activity and CPU usage.
1790 Messages can be redirected, allowing admins to configure
1791 one single logfile for all server messages.
1792 the silc_log_quick global variable to activate fast-logging.
1793 Affected files lib/silcutil/silclog.[ch]
1795 * Changed some code to conform new silclog APIs. Affected
1796 files are doc/example_silcd.conf.in, silcd/server.c
1797 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1800 * Fixed a memory leak that could occur in some situations.
1801 Affected file silcd/serverconfig.c.
1803 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1805 * Added the silc_client_del_client to remove the client from
1806 all channels as well. Affected file lib/silcclient/idlist.c.
1808 * Fixed the client library to correctly remove the client
1809 from all channels when the client entry is being destroyed.
1810 Affected file lib/silcclient/client_notify.c, command.c.
1812 * Added auto-nicking support to the client library. If the
1813 applicatio now sets client->nickname it will be sent to the
1814 server after connecting by the library. This way for example
1815 SILCNICK (or IRCNICK) environment variables will have effect
1816 and always change the nickname automatically to whatever
1817 it is wanted. Affected file lib/silcclient/client.[ch].
1819 * Renamed silc_server_command_bad_chars to the
1820 silc_server_name_bad_chars and moved it to the
1821 silcd/server_util.[ch]. Added also new function
1822 silc_server_name_modify_bad to return nickname that
1823 includes bad characters as new nickname without those
1824 bad characters. This check and modify is now used in
1825 silc_server_new_client when the username is initially set
1826 as nickname, so it must be checked to be valid nickname.
1827 Affected file silcd/packet_receive.c.
1829 * The nickname length is now taken from the packet for real
1830 and not trusted to strlen() since it clearly can return
1831 wrong length for nickname including bad characters. This
1832 also applies to channel names. Affected file silcd/command.c.
1834 * Removed the lib/silcsilm/modules directory. Modules are now
1835 compiled into the lib/silcsim. Fixed the copying of the
1836 modules to follow symbolic links in Makefile.am.pre.
1838 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1840 * Fixed silc_string_regexify list creation. Fixes bugs with
1841 BAN and INVITE commands in server. The affected file is
1842 lib/silcutil/unix/silcunixutil.c.
1844 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1846 * Removed the command destructor entirely from the server's
1847 command and command reply routines. It is not needed, and
1848 its usage was buggy and caused crashes. Affected files are
1849 silcd/command[_reply].[ch].
1851 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1853 * Cancel protocol and NULL sock->protocol if timeout
1854 occurred during protocol. Affected file silcd/server.c.
1856 * Cancel protocol timeouts always before calling the final
1857 callback, to assure that after final callback is called
1858 no other state will be called for the protocol anymore.
1859 Affected file silcd/protocol.c.
1861 * Print error log if incoming connection configuration could
1862 not be found. Affected file silcd/server.c.
1864 * Fixed JOIN command to correctly save the founder mode
1865 to the client on normal SILC server, when the channel
1866 was created by the router. Affected file silcd/command.c.
1868 * Fixed LIST command (hopefully) to send correct reply
1869 packets. Affected file silcd/command.c.
1871 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1873 * The silc_packet_receive_process now returns FALSE if the
1874 read data was invalid packet, and TRUE if it was ok.
1876 The server now checks that if unauthenticated connection
1877 sends data and its processing fails the server will close
1878 the connection since it could be a malicious flooder.
1880 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1882 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1884 * Make sure the warning about error opening a log file is
1885 printed only once and not everytime it fails (produces
1886 too much useless log). Affected file lib/silcutil/silclog.c.
1888 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1890 * Made the silc_server_daemonise() function more readable.
1891 Affected file silcd/server.c.
1893 * Pid file is now optional, the user may comment it out from
1894 the config file. Removed define SILC_SERVER_PID_FILE, we
1895 don't need a default any longer. Affected file
1896 configure.in.pre, lib/Makefile.am.pre.
1898 * Make some use of the pid file. The server now dies at startup
1899 if it detects a valid pid file on his path. The server would
1900 die anyway in this circumstance, because of the bind() failure.
1901 Affected file silcd/silcd.c.
1903 * No longer compiling lib/dotconf.
1905 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1907 * Fixed JOIN command parsing not to crash. Affected file
1908 lib/silcclient/command.c.
1910 * Fied the NICK_CHANGE notify to add the new client entry
1911 even it is resolved. This removes an <[unknown]> nick
1912 thingy bug in the client. Affected file is
1913 lib/silcclient/client_notify.c.
1915 * Do not try to allocate 0 bytes (efence does not like it)
1916 in lib/silccore/silccomand.c when encoding payload.
1918 * Do not take IRCNICK as nickname in Irssi SILC client since
1919 it is not possible to set nickname before hand connecting
1920 the server (TODO has an entry about adding auto-nicking
1923 * Changed the silc_server_command_pending to check whether
1924 there already exists an pending entry with the specified
1925 command, command identifier and pending callback. This is
1926 to fix IDENTIFY and WHOIS related crashes that may register
1927 multiple pending commands with same identifier. Affected
1928 file silcd/command.c.
1930 * Fixed the server to reconnect to the router even if it
1931 was already reconnecting and EOF was received. This to
1932 fix a possibility that the server wouldn't ever try to
1933 auto-reconnect to the router. Affected file silcd/server.c.
1935 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1937 * Fixed the server's password authentication to use the
1938 length of the locally saved password, and not the one
1939 sent in the packet. Affected file silcd/protocol.c.
1941 * Fixed same password authentication problem in the
1942 Authentication Payload handling routines in
1943 lib/silccore/silcauth.c.
1945 * Yet another password authentication problem fixed with
1946 channel password handling in silcd/command.c.
1948 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1950 * If first character of string in silc_parse_userfqdn is '@'
1951 then do not parse it. Affected file is
1952 lib/silcutil/silcutil.c.
1954 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1956 * Fixed minor bug in IDENTIFY command reply sending, which
1957 caused various weird problems during JOIN when it was
1958 resolving names for users. Affected file silcd/command.c.
1960 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1962 * Fixed the IDENTIFY command reply sending to chech better valid
1963 clients. It was possible to send incomplete list of replies.
1964 Affected file silcd/command.c.
1966 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1968 * Added silc_client_command[s]_[un]register functions now to
1969 dynamically register the commands in client library. Removed
1970 the static table of commands. This allows the client library
1971 to call commands without causing the application to know about
1972 what commands library has called.
1974 Removed the INFO command reply kludge to detect when the command
1975 was called by library. Now library use its own command reply
1976 function for INFO command.
1978 Added function silc_client_command_call to call a command.
1979 Application can use it to call command, not access the structure
1982 Now all commands that are sent by the client library (not
1983 explicitly sent by application) use own command reply functions.
1985 Affected files around lib/silcclient/ and in
1986 irssi/src/silc/core/.
1988 * Fixed the WHOIS command reply sending to chech better valid
1989 clients. It was possible to send incomplete list of replies.
1991 Fixed the WHOIS and IDENTIFY to send the request to router
1992 if normal server did not do it and did not find any results.
1994 Affected file silcd/command.c.
1996 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1998 * Moved the internal data from SilcClient context into its
1999 own file, not accesible to application. Affected files
2000 lib/silcclient/client.h and lib/silcclient/client_internal.h,
2001 and other files in client library.
2003 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2005 * Added doc/examples installation target in Makefile.am.pre.
2008 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2010 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
2011 commands the found client entry will be removed from the
2012 cache, after notifying application about the error. Affected
2013 file lib/silcclient/command_reply.c.
2015 * Changed the /MSG to check for exact nickname user gave, and
2016 not let `nick' match `nick@host' if it is only one found. Now,
2017 user must type the exact nickname (like nick@host2) even if
2018 there are no more than one same nicks found. This is to avoid
2019 a possibility of sending nickname to wrong nickname since
2020 `nick' could match `nick@host'. Affected file is
2021 irssi/src/core/silc-servers.c.
2023 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2025 * Do not print "you are now server operator" or similar when
2026 giving /away command. Affected files are
2027 irssi/src/silc/core/client_ops.c, silc-servers.h.
2029 * Made the silc_server_command_pending_error_check to send
2030 the same command reply payload it received back to the
2031 original sender of the command. This way all arguments
2032 that was received by the server will be received by the
2033 client too. Affected file silcd/command.c.
2035 * Added the silc_idcache_add to return the created cache entry
2036 to a pointer. Affected file lib/silccore/silcidcache.[ch].
2038 * Add global clients to expire if they are not on any channel.
2039 This is because normal server will never know if they signoff
2040 if they are not on any channel. The cache expiry will take
2041 case of these entries. This is done by normal servers only.
2042 The affected files are silcd/command_reply.c,
2043 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
2045 * If server receives invalid ID notification for WHOIS or
2046 IDENTIFY and the ID exists in the lists, it is removed.
2047 Affected file silcd/command_reply.c.
2049 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
2050 in client then client entry that it matches is searched and
2051 the nickname is printed on the screen for user. Affected
2052 file irssi/src/silc/core/client_ops.c.
2054 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2056 * Use cache entry expire time in the LIST command reply to
2057 purge old entries from the cache after the LIST command
2058 reply has been received. This way we don't have non-existent
2059 entries in the cache for too long. Affected file is
2060 silcd/command_reply.c.
2062 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2064 * If we are normal server, and we've not resolved client info
2065 in WHOIS or IDENTIFY from router, and it is global client,
2066 we'll check whether it is on some channel. If it is not
2067 then we cannot be sure about its validity and will resolve it
2068 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
2069 file silcd/command.c.
2071 * Search channel by name (if possible) rather than by ID
2072 in IDENTIFY command's command reply. Affected file is
2073 silcd/command_reply.c.
2075 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2077 * Distribute to the channel passphrase in CMODE_CHANGE notify.
2078 Updated specs and implemented it. Affected file silcd/command.c,
2079 silcd/packet_send.c and silcd/packet_receive.c.
2081 * Implemented the <founder auth> payload handling in the JOIN
2082 command. If provided all conditions for channel joining
2083 except requirement to provide correct passphrase can be
2084 overrided by the channel founder. Updated the protocol specs.
2085 Affected file silcd/command.c.
2087 Added support for founder auth in JOIN command in client
2088 library. Fixed the parsing of the JOIN command now to support
2089 all options as they should be. The affected file is
2090 lib/silcclient/command.c.
2092 * Optimized the WHOIS and IDENTIFY commands to send the request
2093 to router only if it includes nicknames or other names. If
2094 they include only IDs then check the local cache first before
2095 routing. Affected file is silcd/command.c.
2097 * Added channels topic announcements. Affected file is
2098 silcd/packet_receive.c and silcd/server.c.
2100 * Fixed the silc_server_send_notify_topic_set to really destine
2101 the packet to channel. Affected file silcd/packet_send.c.
2103 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
2104 library. Affected file lib/silcclient/client_notify.c.

2118 lib/silccore/silcidcache.c
2123 * ROBOdoc documented the lib/silcske/groups.h file and a
2124 bit changed the interface for better.
2126 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2128 * Update the client entry context in the ID cache after
2129 nick change. Affected file lib/silcclient/command.c.
2130 Fixes the CUMODE command when regaining founder privileges,
2131 and a little WHOIS problem.
2133 * Fixed silc_net_gethostbyname to correctly call the
2134 inet_ntop. Affected file lib/silcutil/silcnet.c.
2136 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2138 * Added IPv6 support checking to the configure.in.pre, added
2139 also --enable-ipv6 option to override the check. Affected
2140 file configure.in.pre.
2142 * The silc_thread_create now calls the start function
2143 directly if threads support is not compiled in. Removes
2144 ugly #ifdef's from generic code. Affected files are
2145 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
2147 * Added silc_net_gethostby[name/addr]_async to asynchronously
2148 resolve. Affected files are lib/silcutil/silcnet.[ch].

2153 * Added support for creating IPv6 based server IDs. Affected
2154 file is silcd/serverid.c.
2156 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2158 * Added silc_net_gethostby[addr/name] into the
2159 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
2160 routines. Added silc_net_is_ip[4/6]. Affected file is
2161 lib/silcutil/unix/silcunixnet.c. All routines that take
2162 address as argument now supports both IPv4 and IPv6 addresses.
2164 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2166 * Fixed LIST command reply sending in server. Affected file
2169 * Server now sends the kicker's client ID in the KICK notify
2170 to the kicked client. Affected file silcd/command.c.
2172 * The client library now parses the kickers client ID and
2173 UI displays it. Affected files lib/silcclient/client_notify.c
2174 and irssi/src/silc/core/silc-channels.c, module-formats.c.
2176 * Made all payload parsing function prototypes consistent.
2177 They all take now const unsigned char * and uint32 pair as
2178 the payload data instead of SilcBuffer. Changes all around
2179 the source tree. Other unsigned char* -> const unsigned char*
2180 changes around the tree as well.
2182 * Optimized SFTP client and server packet sending not to
2183 allocate new buffer for each packet but to recycle the
2184 first allocated buffer. Affected files are
2185 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
2187 * Optimized the SFTP client to use SilcList instead of
2188 SilcDList for requests, because it is faster. Affected file
2189 is lib/silcsftp/sftp_client.c.
2191 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
2192 into lib/silccore/silcid.[ch].
2194 Renamed silcpayload.[ch] into silcargument.[ch].
2196 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2198 * If client entry is deleted with active key agreement
2199 session, abort the session.
2201 The silc_client_abort_key_agreement now calls the completion
2202 callback with new SILC_KEY_AGREEMENT_ABORTED status.
2204 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
2207 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2209 * Don't use __restrict in older GCC's. Affected file is
2210 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
2212 * silc_net_localhost now attempts to reverse lookup the
2213 IP/hostname. Affected file lib/silcutil/silcnet.c.
2215 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
2216 command. It can be used to gain founder privileges at
2217 the same time when joining the channel.
2219 Defined that the SILC_NOTIFY_TYPE_KICKED send the
2220 kicker's client ID as well. Updated protocol specs.
2222 Defined that the server must send SILC_COMMAND_IDENTIFY
2223 command reply with error status to client who sent
2224 private message with invalid client ID.
2226 Updated the protocol specification.
2228 * Added silc_server_send_command_reply to send any
2229 command reply. Affected file silcd/packet_send.[ch].
2231 * Added silc_id_payload_encode_data to encode ID payload
2232 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
2234 * The server now send IDENTIFY command reply with error
2235 status if client ID in private message is invalid. Affected
2236 file silcd/packet_receive.c.
2238 * Save the server key file with server's IP address in
2239 the filename instead of hostname. The affected file is
2240 irssi/src/silc/core/client_ops.c.
2242 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2244 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
2247 * Added libtool support for compiling shared objects in
2248 lib/silcsim. Affected file configure.in.pre and
2249 lib/silcsim/Makefile.am. Original patch by cras.
2251 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2253 * Pid file configuration, and server's config file fixes
2254 patch by toma. Updated CREDITS file.
2256 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2258 * Fixed silc_client_channel_message to not try to decrypt
2259 the message twice if it resolved the destination client
2260 information. This could cause of dropping one channel
2261 message. Affected file lib/silcclient/client_channel.c.
2263 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2265 * Added silc_client_run_one into lib/silcclient/silcapi.h and
2266 lib/silcclient/client.c. This function is used when the SILC
2267 Client is run under some other scheduler, or event loop or
2268 main loop. On GUI applications, for example this may be
2269 desired to used to run the client under the GUI application's
2270 main loop. Typically the GUI application would register an
2271 idle task that calls this function multiple times in a second
2272 to quickly process the SILC specific data.
2274 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2276 * Fixed silc_server_drop() for dropping the supplementary
2277 groups as well, this could cause a security hole on some
2280 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2282 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
2285 * Write PID file after dropping privileges. Added -F option
2286 to run server on foreground. A patch by debolaz.
2287 Affected files silcd/server.c, silcd/silcd.c.
2289 * Fixed MOTD to return the MOTD file server name. Affected
2290 file silcd/command.c.
2292 * Added INFO command reply handling to the Irssi SILC Client.
2293 Affected file irssi/src/silc/core/client_ops.c.
2295 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2297 * Fixed the silc_idcache_list_* routines to really support
2298 the dynamic list. Fixes a crash. Affected file is
2299 lib/silccore/silcidcache.c.
2301 * Fixed the LIST command reply to really call LIST command's
2302 pending callbacks. Affected file silcd/command_reply.c.
2304 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2306 * Update conn->local_entry->nickname after giving NICK
2307 command. Affected file lib/silcclient/command.c.
2309 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
2311 * Added the [pid] option to the silcd configuration file
2313 Affected files: serverconfig.[ch] and silcd.c
2315 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2317 * Save fingerprint in WHOIS command reply in server.
2318 Affected file silcd/command_reply.c.
2320 * Fixed NICK commands pending callback registration.
2321 Affected file lib/silcclient/command.c.
2323 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2325 * Use ++server->cmd_ident when sending commands in server,
2326 instead of random number. Affected file silcd/command.c.
2328 * Fixed GETKEY command reply to call actually GETKEY pending
2329 command callbacks. Affected file silcd/command_reply.c.
2331 * A bit stricter check for nicknames. Check for same nickname
2332 in NICK command also. Affected file silcd/command.c.
2334 * Do not call INFO command everytime client ID changes, only
2335 during first connecting. Affected file lib/silcclient/client.c.
2337 * Set the new nickname only after successful command reply for
2338 NICK command is returned by server. Affected file
2339 lib/silcclient/command.c.
2341 * Remove nicknames from nicklist during server_signoff notify.
2342 Should fix /NAMES bit more. The affected file is
2343 irssi/src/silc/core/silc-channels.c.
2345 * Added `fingerprint' field to the SilcIDListData in the
2346 silcd/idlist.h to hold the fingerprint of the client's
2349 Send the fingerprint of the client's public key in WHOIS
2352 Affected files silcd/command.c, and silcd/idlist.[ch].
2354 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
2355 create fingerprint from given data.
2357 * Show the fingerprint of the client's public key in WHOIS.
2358 Affected files irssi/src/module-formats.[ch] and
2359 irssi/src/silc/core/client_ops.c.
2361 * Format the multiple same nicknames also during JOIN and
2362 NICK_CHANGE notifys. Affected file is
2363 lib/silcclient/client_notify.c.
2365 * Do not print error on screen for invalid private message
2366 payload since it can come if someone is sending private
2367 messages with wrong key. Affected file
2368 lib/silccore/silcprivate.c.
2370 * Fixed multiple concurrent /PING crash. Affected file
2371 lib/silcclient/command.c.
2373 * Changed the wrong ID encoding. All IP addresses must be
2374 in MSB first order in encoded format. They were encoded
2375 wrong and was in LSB format. Affected files are
2376 silcd/serverid.c, lib/silcutil/silcutil.c.
2378 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
2380 * Call the `connect' client operation through the scheduler
2381 in case of error. Affected file lib/silcclient/client.c.
2383 * Call the `failure' client operation even if the error
2384 occurred locally during a protocol. Affected file is
2385 lib/silcclient/protocol.c.
2387 * Added support of sending LIST command to router from normal
2388 server. This way normal server can get list of all channels
2389 in the network too. Fixed the channel list sending in the
2390 server too. Affected files are silcd/command.c, and
2391 silcd/command_reply.[ch].
2393 * Added silc_server_update_channels_by_server and
2394 silc_server_remove_channels_by_server. They are used during
2395 disconnection of primary router and in backup router protocol.
2396 Affected file silcd/server_util.[ch], silcd/server.c and
2397 silcd/server_backup.c.
2399 * Fixed channel adding to global list in IDENTIFY command
2400 reply in server. Affected file silcd/command_reply.c.
2402 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2404 * If the incoming packet type is REKEY or REKEY_DONE process
2405 that packet always synchronously. Fixes yet another MAC
2406 failed error on slow (dialup) connections. Affected file
2407 lib/silcclient/client.c and silcd/server.c.
2409 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2411 * Call check_version SKE callback for initiator too. Affected
2412 file lib/silcske/silcske.c.
2414 * Implemented fix for security hole found in the SKE that was
2415 fixed in the specification few days back; the initiator's
2416 public key is now added to the HASH value computation.
2417 Added backwards support for the old way of doing it too, for
2418 old clients and old servers. Affected file is
2419 lib/silcske/silcske.c.
2421 * Enabled mutual authentication by default in SKE. If initiator
2422 is not providing mutual authentication the responder will
2423 force it. This will provide the proof of posession of the
2424 private key for responder. The affected files are
2425 lib/silcclient/protocol.c and silcd/protocol.c.
2427 * Do not cache anymore the server's public key during SKE.
2428 We do mutual authentication so the proof of posession of
2429 private key is done, and if the server is authenticated in
2430 conn auth protocol with public key we must have the public
2431 key already. Affected file silcd/protocol.c.
2433 * Added new global debug variable: silc_debug_hexdump. If
2434 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
2435 file lib/silcutil/silclog.[ch].
2437 * Fixed compilation warning due to char * -> const char *.
2438 Affected files lib/silcutil/silcnet.h, and
2439 lib/silccore/silcauth.[ch].
2441 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2443 * Fixed CMODE command when new channel key was created. If
2444 the creation failed the old key was removed. Next time giving
2445 same command would crash the server since the old key was
2446 freed already. Affected file silcd/command.c.
2448 * Fixed the silc_server_announce_get_channels to not crash
2449 on reconnect. Affected file silcd/server.c.
2451 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2453 * Added silc_log_set_debug_string function to set a regex
2454 string to match for debug output. Only the function names,
2455 or filenames matching the given debug string is actually
2456 printed. This way it is possible to filter out those debug
2457 strings that user is not interested in.
2459 Fixed a bug in silc_string_regexify.
2461 Affected files lib/silcutil/silclog.[ch], and
2462 lib/silcutil/unix/silcunixutil.c.
2464 * Changed the -d options in both server and Irssi SILC client
2465 to take the debug string as argument. Affected files
2466 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
2468 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2470 * Added silc_hash_babbleprint to create a Bubble Babble
2471 Encoded fingerprint. The encoding is developed by Antti
2472 Huima (draft-huima-babble-01.txt), and it creates human
2473 readable strings out of binary data. Affected file
2474 lib/silccrypt/silchash.[ch].
2476 * Print the babble print now in addition of fingerprint as well
2477 in Irssi SILC client. Affected files are
2478 irssi/src/fe-common/silc/module-formats.[ch],
2479 irssi/src/fe-common/silc/core/client_ops.c.
2481 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2483 * Fixed a security problem found in SKE. The initiator's
2484 public key too is now added to the HASH hash value creation
2485 which is signed by the responder to create the SIGN value.
2486 This will prevent anyone in the middle to lie to the responder
2487 about the initiator's public key. If this is done now, the
2488 man in the middle will get caught. Updated the protocol
2491 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2493 * Better installation directory handling. Configure module
2494 paths and other paths automatically to example_silc* files
2495 in doc/. A patch by toma.
2497 * Fixed compiler warning from MPI library, and from SILC RNG.
2500 * Added SILC_SERVER_PID_FILE to define the pid file for server.
2501 It can be configured with ./configure. A patch by toma.
2503 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2505 * Find correct make to use in prepare-clean. A patch by
2506 toma. Affected file prepare-clean.
2508 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
2510 * Added irssi variables use_auto_addr, auto_bind_ip,
2511 auto_bind_port and auto_public_ip.
2513 * Changed the interface for silc_client_send_key_agreement
2514 in lib/silcclient/silcapi.h
2518 irssi/src/silc/core/silc-core.c
2520 lib/silcclient/silcapi.h
2521 irssi/src/silc/core/silc-channels.c
2522 lib/silcclient/client_keyagr.c
2525 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2527 * Added silc_pkcs_public_key_compare to compare two
2528 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
2530 * Check that the client who set the founder mode on the
2531 channel is the same client that is giving the founder
2532 mode to itself. It is done by comparing the saved public
2533 key (it is saved even in the authentication is passphrase).
2534 Affected file silcd/command.c.
2536 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2538 * Do not process packet for disconnected socket connection.
2539 Affected file lib/silccore/silcpacket.c.
2541 * Process the DISCONNECT packet through scheduler in the
2542 client library. Affected file lib/silcclient/client.c.
2544 * Fixed the silc_client_packet_parse to not to increase
2545 the packet sequence number if the conn->sock and the
2546 current socket connection is not same. This can happen
2547 for example during key agreement when the conn includes
2548 multiple socket connections (listeners). Affected file
2549 lib/silcclient/client.c.
2551 * The sender of the file transfer request now provides also
2552 the pointer (listener) for the key exchange protocol. If
2553 the listener cannot be created then it sends empty key
2554 agreement and lets the receiver provide the listener.
2556 Added `local_ip' and `local_port' arguments to the
2557 silc_client_file_send. If they are provided they are used,
2558 if not then it will attempt to find local IP address, if
2559 not found or bind fails then the remote client will provide
2562 Affected files are lib/silcclient/client_ftp.c and
2563 lib/silcclient/silcapi.h.
2565 * Extended the FILE SEND command to support defining the
2566 local IP and port for key exchange listener. They are
2567 optional. Affected file irssi/src/silc/core/silc-servers.c.
2569 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2571 * Defined to WHOIS command reply the sending of fingerprint
2572 of the client's public key (if the proof of posession of the
2573 corresponding private key is verified by the server).
2574 Updated to the protocol specification.
2576 * Added support of receiving the client's public key's
2577 fingerprint in command reply in client library. Affected
2578 file is lib/silcclient/command_reply.c, and
2579 lib/silcclient/idlist.[ch].
2581 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2583 * Do not send over 128 chars long nickname to the server
2584 in NICK command. Affected file lib/silcclient/command.c.
2586 * Do not send over 256 chars long channel names to the server
2587 in JOIN command. Affected file lib/silcclient/command.c.
2589 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2591 * Assure that silc_server_close_connection cannot be called
2592 twice for same socket context. Affected file is
2595 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2597 * Send error message to application if opening file for
2598 writing during file transfer fails. Affected file is
2599 lib/silcclient/client_ftp.c.
2601 Remove all file transfer sessions for a client that we're
2602 removing from ID cache.
2604 Affected file is lib/silcclient/client_ftp.c.
2606 * Fixed silc_net_addr2bin to return correct address. Affected
2607 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2609 * Fixed file transfer session removing on signoff notify.
2610 Affected file irssi/src/silc/core/silc-servers.c.
2612 * Added the SilcClientFileError to be returned in the monitor
2613 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.

2634 client library. Affected file lib/silcclient/client_prvmsg.c.
2636 * Do not actually remove the client directly from ID cache
2637 during SERVER_SIGNOFF, but invalidate it. This way we
2638 preserve the WHOWAS info for the client. Affected file
2639 silcd/server_util.c.
2641 * Fixed SERVER_SIGNOFF notify handling in the server. The
2642 server is now able to process incoming SERVER_SIGNOFF notify
2643 for a server that it doesn't even know about. It will remove
2644 the clients provided in the notify. Affected file
2645 silcd/packet_receive.c.
2647 * Check for partial packet in data queue after every packet that
2648 was found from the queue. Return and wait for more data if
2649 there is partial data in queue. Affected file is
2650 lib/silccore/silcpacket.c.
2652 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>

2663 * Added better monitor of file transfers. It now monitors
2664 key agreement protocol during the file transfer too. Added
2665 error reporting too. Affected files
2666 irssi/src/silc/core/silc-servers.c,
2667 irssi/src/fe-common/silc/module-formats.[ch].
2669 * Wrote a help file for FILE command.
2671 * Added silc_rng_global_get_byte_fast to get not-so-secure
2672 random data as fast as possible. Random data is read from
2673 /dev/urandom if available and from the SILC RNG if not
2674 available. It is used in padding generation. Affected file
2675 lib/silccrypt/silcrng.[ch].
2677 * All packets in client library are now processed synchronously.
2678 Optimized packet processing a lot. Affected file
2679 lib/silcclient/client.c.
2681 * All server connection packets are processing synchronously
2682 now in server, to optimize packet processing. Affected file
2685 * Include files are installed now only in Toolkit distribution
2686 if make install is given. Affected files: all Makefile.am's.
2688 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2690 * Assure that silc_client_notify_by_server_resolve does not
2691 resolve the client information multiple times. If it cannot
2692 be found by the first it cannot be found at all. Affected
2693 file lib/silcclient/client_notify.c.
2695 * Fixed WHOWAS command reply calling. Affected file
2696 lib/silcclient/command_reply.c.
2698 * Removed all references to silc_idlist_get_client from the
2699 Irssi SILC client since that call is internal call used by
2700 the library. The Irssi SILC client will use now client
2701 retrieval functions found in silcapi.h.
2703 * Fixed a bug in resolving nickname info before sending
2704 private message. It used freed memory. Affected file
2705 irssi/src/silc/core/silc-servers.c.
2707 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2709 * Assure my_channels statistics cannot go negative in server.
2710 Affected files silcd/server.c, silcd/server_util.c.
2712 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

2726 * Added silc_net_localip to return local host's IP address.
2727 Affected file lib/silcutil/silcnet.[ch].
2729 * If key exchange or rekey protocol is active for a connection
2730 parse all packets syncronously since there might be packets
2731 in packet queue that we are not able to process without first
2732 processing packets before them. Affected file silcd/server,
2733 lib/silcclient/client.c.
2735 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2736 whether library should continue processing the packet.
2737 Affected file lib/silccore/silcpacket.h.

2783 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
2784 is incomplete and is being resolved, it won't be resolved
2787 Make sure also that USERS command reply does not resolve
2788 twice information. Affected file is
2789 lib/silcclient/command_reply.c.
2791 Make sure that silc_client_get_clients_by_list does not
2792 resolve twice same information.
2794 * Check for valid client->id in the silc_server_free_client_data.
2795 Affected file silcd/server.c.
2797 * Fixed /GETKEY nick@server not to crash if the server entry
2798 is not found. Affected file lib/silcclient/command.c.
2800 * Fixed the silc_server_check_cmode_rights to check the
2801 requested modes correctly. Affected file silcd/command.c.

2806 Affected file silcd/command.c.
2808 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2810 * Call the silc_server_udpate_servers_by_server in the
2811 primary router that comes back online in the backup resuming
2812 protocol. Otherwise it routes packets wrong. Affected file
2813 silcd/server_util.[ch], silcd/server_backup.c.
2815 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2817 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2818 lib/silcutil/silcbuffmt.[ch].
2820 * Redefined the SILC packet header to include the padding
2821 length. Affected file lib/silccore/silcpacket.[ch].
2823 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2824 length for maximum padding up to 128 bytes). Affected
2825 file lib/silccore/silcpacket.h.
2827 * Removed all backwards support for old 0.5.x MAC thingies.
2828 The SILC packet header change makes it impossible to be
2829 backwards compatible.
2831 * Send the ENDING packet with timeout in the backup resuming
2832 protocol. This is to assure that all routers has connected
2833 to the primary router. Affected file silcd/server_backup.c.
2835 * Changed the RNG to take the first IV from random data. It
2836 used to take it from zero actually. Changed the RNG also
2837 to use /dev/urandom during session. /dev/random is used
2838 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2840 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2842 * Changed the SILC packet header to have the first two bytes
2843 (the packet length) encrypted. Affected files aroung the
2844 code tree, lib/silccore/silcpacket.[ch]. Removed the
2845 SilcPacketCheckDecrypt callback. It is not needed anymore
2846 since the silc_packet_receive_process will determine now
2847 whether the packet is normal or special.
2849 * Implemented the unidirectional MAC keys. Affected files
2850 lib/silcske/silcske.c, silcd/protocol.c and
2851 lib/silcclient/protocol.c.
2853 * Implemented the packet sequence number to the MAC computation.
2854 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
2855 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
2856 lib/silcclient/protocol.c.
2858 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2860 * Allow backup router to announce servers. All servers
2861 announced by backup router are added to the global list
2862 automatically. Update hte server's socket to our primary
2863 router also when backup router announces a server.
2864 Affected file silcd/packet_receive.c.
2866 * Do not update the client->router in the function
2867 silc_server_udpate_clients_by_server if the client is on
2868 global list. We might fail to find any specific server
2869 for locally connected clients and local cell clients. They
2870 should still use the `from' and not `to' as client->router.
2871 This fixes backup router resuming protocol. Affected file
2872 silcd/server_util.c.
2874 * Decrease channel statistics count only if the channel
2875 deletion worked. Affected files are silcd/server.c and
2876 silcd/server_util.c.
2878 * Added silc_server_update_servers_by_server to update origin
2879 of all server entries. Used during backup router protocol.
2880 Affected files silcd/server_util.[ch], silcd/server.c. and
2881 silcd/backup_router.c.
2883 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
2884 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
2885 silc_hmac_get_hash and silc_hmac_get_name. Affected file
2886 lib/silccrypt/silchmac.c.
2888 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2890 * Assure that router cannot reroute the same channel message
2891 to the sender. Affected file silcd/packet_receive.c.
2893 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2895 * Made better checks that the channel message is not sent
2896 to the router it came from. Affected file is
2897 silcd/packet_send.c. Fixed memory leak too.
2899 * Announce informations for incoming router connection, but
2900 only after checking if it is replaced by backup router.
2901 Affected file silcd/packet_receive.c.
2903 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2905 * Fixed the backup resuming protocol to work in multiple
2906 router environment. Affected file silcd/server_backup.c.
2908 * Route packet only to one router in the function
2909 silc_server_packet_send_to_channel. Affected file is
2910 silcd/packet_send.c.
2912 * Fixed silc_server_send_notify_dest to set the broadcast
2913 flag. Fixed the silc_server_send_notify_topic to actually
2914 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2915 Affected file silcd/packet_send.c.
2917 * Changed the SFTP Filesystem interface. Changed the
2918 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2919 the filesystem operation function. The SilcSFTPFilesystem
2920 is now a context that is allocated by all filesystem allocation
2921 functions and it already includes the operations structure
2922 and filesystem specific context. It is given as argument
2923 now to the silc_sftp_server_start. This made the interface
2924 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2925 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2927 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2929 * Changed the backup router adding and getting interfaces
2930 in the server. The router that will be replaced by the
2931 specified backup router is now sent as argument. Affected
2932 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2935 * Added silc_net_addr2bin_ne to return the binary form of
2936 the IP address in network byte order. Affected files
2937 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
2939 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2941 * Check for existing server ID in silc_server_new_server
2942 and in silc_server_connect_to_router_final and remove the
2943 old entry if it exists. Affected file silcd/packet_receive.c,
2946 * Send the channel message always to only one router, either
2947 in upstream or downstream. Affected file is
2948 silcd/packet_send.c.
2950 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2952 * Wrote the definition of the backup resuming protocol to the
2953 protocol specification.
2955 * Removed one redundant channel key generation from normal
2956 server during joining procedure. Removed one redundant
2957 channel key sending from server to router during joining
2958 procedure. Affected file silcd/command.c.
2960 * Made minor bugfixes to the backup router resuming protocol.
2961 Affected file silcd/server_backup.c, server.c.
2963 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2965 * Added --disable-asm configuration option. Affected files
2966 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
2969 * Implemented the backup resuming protocol that is used to
2970 resume the primary router position in the cell after the
2971 primary router comes back online. Affected files
2972 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
2973 and silcd/server_util.[ch].
2975 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2977 * Sleep two (2) seconds after sending QUIT command to server.
2978 Affected file lib/silcclient/command.c.
2980 * Assure that if outgoing data buffer is pending do not force
2981 send any data. Affected file silcd/packet_send.c.
2983 * Assure that if outgoing data buffer is pending do not force
2984 send any data. Affected file lib/silcclient/client.c.
2986 * Implemented the backup router support when the primary router
2987 goes down. The servers and routers can now use the backup
2988 router as new primary router without loosing connectivity.
2990 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2992 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
2993 in the server to indicate disabled entry. All data read
2994 from the connection will be ignored and no data is sent
2995 for entry that is disabled. Affected files are
2996 silcd/idlist.h, silcd/server.c.
2998 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3000 * Created SFTP client and server test programs in the
3001 lib/silcsftp/tests directory.
3003 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3005 * Implemented memory filesystem (virtual filesystem) for
3006 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
3009 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3011 * Implemented the SFTP (SSH File Transfer Protocol) to the
3012 lib/silcsftp. It includes SFTP client and SFTP server
3015 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3017 * Moved lib/silccore/silcprotocol.[ch] to the
3018 lib/silcutil library.
3020 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
3021 take variable argument list pointer as argument. Affected
3022 file lib/silcutil/silcbuffmt.[ch].
3024 * Added silc_buffer_set function that is used to set data
3025 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
3026 Affected file lib/silcutil/silcbuffer.h.
3028 * Changed various routines in the core library to use the new
3029 silc_buffer_set instead of allocating new buffer only for
3032 * Added 64-bit value formatting and unformatting support to the
3033 silc_buffer_[un]format routines. Affected file is
3034 lib/silcutil/silcbuffmt.[ch].
3036 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
3037 to includes/bitmove.h.
3039 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3041 * Fixed channel user mode saving in client library. Affected
3042 file lib/silcclient/command[_reply].c.
3044 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3046 * Defined the file transfer to the SILC Protocol. Added
3047 new packet type SILC_PACKET_FTP and defined File Transfer
3048 Payload. The mandatory file transfer protocol is SFTP
3049 (SSH File Transfer Protocol). Affected file in addition
3050 of the internet draft is lib/silccore/silcpacket.h.
3052 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
3053 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
3054 is used as part of backup router protocol when the primary
3055 router of the cell is back online and wishes to resume
3056 the position as primary router.
3058 * Redefined the MAC generation keys in the protocol. The
3059 same key is not used anymore in both direction. Both
3060 direction will now use different keys for sending and
3061 receiving. This fixes a potential security flaw. This
3062 change causes incompatibilities in the protocol.
3064 * Redefined also the MAC computation from the packet.
3065 An packet sequence number is now added to the MAC
3066 computation. This prevents possible replay attacks against
3067 the protocol. This change too causes incompatibilities
3070 Added `sequence' field to the SilcPacketContext to hold
3071 the current sequence number for the packet.
3073 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3075 * Added `created' field to the SilcIDListData in the file
3076 silcd/idlist.h to indicate the time when the entry was
3079 * Added `created' field to the SilcChannelEntry too. Affected
3080 file silcd/idlist.h.
3082 * Added `creation_time' aguments to all the announcement functions
3083 in the server. If it is provided then only the entries that
3084 was created after the provided time frame are actually
3085 announced. Affected file silcd/server.[ch].
3087 * The protocol says that the Channel ID's IP address must be
3088 based on the router's IP address. Added check for this in
3089 the silc_server_new_channel when processing incoming New Channel
3090 Payload. Affected file silcd/packet_receive.c.
3092 * Print out the correct version with --version in SILC client.
3093 Affected file irssi/src/silc/core/silc-core.c.
3095 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3097 * Fixed WHOWAS command to check for completnes of the client
3098 entry always, not just when the command is coming from client.
3099 Affected file silcd/command.c.
3101 * Added new function silc_server_packet_queue_purge to purge the
3102 outgoing data queue to the network. After the function returns
3103 it is guaranteed that the outgoing packet queue is empty.
3104 Affected file silcd/packet_send.[ch].
3106 * Purge the outgoing packet queue in the rekey protocol's final
3107 callback to assure that all rekey packets go to the network
3108 before quitting the protocol. Affected file silcd/server.c.
3110 * Added silc_client_packet_queue_parse as similar function as
3111 in server to the client library. The affected file is
3112 lib/silcclient/client.c.
3114 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3116 * Splitted silcd/server.c and created silcd/server_util.[ch]
3117 for utility functions.
3119 * Added new socket flag SILC_SF_DISABLED to indicate that the
3120 connection is open but nothing can be sent to or received from
3121 the connection. Affected file lib/silcutil/silsockconn.[ch].
3122 The checking for disabled socket is checked in the low level
3123 silc_socket_write and silc_socket_read functions.
3125 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3127 * Allow only nicknames and channel names that fits into the
3128 7-bit unsigned char ASCII set. Affected file silcd/command.c.
3130 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3132 * When processing JOIN command reply in server check that if
3133 the channel exists in our global list we'll move it the local
3134 list. Affected file silcd/command_reply.c.
3136 * Fixed the check whether client is joined on the channel already
3137 in JOIN command. Affected file lib/silcclient/command.c.
3139 * Fixed the JOIN command reply to check whether the channel
3140 already exists. Affected file lib/silcclient/command_reply.c.
3142 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3144 * Added silc_ske_status_string to map the SKE error numbers
3145 to readable strings. The affected files are
3146 lib/silcske/silcske[_status].[ch].
3148 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3150 * Do not show the private channels on the WHOIS channel list
3151 as it is not allowed by the protocol. The affected file is
3154 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3156 * Assure that the packet length digged from the actual packet
3157 is something sensible in the silc_packet_decrypt_rest_special
3158 in lib/silccrypt/silcpacket.c.
3160 * Free and NULL the allocated pointer in silc_hmac_alloc if
3161 the HMAC allocation fails. The affected file is
3162 lib/silccrypt/silchmac.c.
3164 * Print the selected security properties to the log files in
3165 the server. Affected file silcd/protocol.c.
3167 * Add SKE's reference counter even if calling the completion
3168 callback manually. Otherwise it goes negative, although it
3169 does not cause any problems. The affected file is
3170 lib/silcske/silcske.c.
3172 * Remove the client entry with short timeout after giving the
3173 KILL command. Affected file lib/silcclient/command.c.
3175 * Fixed to send error reply in WHOIS and IDENTIFY commands in
3176 case all found clients are already disconnected (WHOWAS would
3177 found them) in the server. Affected file silcd/command.c.
3179 * Update the last_receive (time of last data received) to be
3180 updated only when received private or channel message so that
3181 the idle time showed in WHOIS makes more sense.
3183 * Added boolean field `valid' in to the SilcClientEntry in the
3184 client library to indicate whether the entry is valid or not.
3185 This fixes the nickname change bug on channel when changing
3186 the nickname to be same than the old (like nick to Nick) the
3187 nickname formatter doesn't set the new nick anymore to Nick@host.
3188 Affected file lib/silcclient/idlist.[ch].
3190 * Now actually fixed the nickname changing on disconnection.
3191 Added new function silc_change_nick to the Irssi SILC Client.
3192 Affected file irssi/src/silc/core/client_ops.c,
3193 irssi/src/silc/core/silc-nicklist.[ch].
3195 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3197 * Check that the public key exists in the GETKEY command before
3198 trying to encode it. Affected file silcd/command.c.
3200 * Print some notifications on received public keys with GETKEY
3201 command in the Irssi SILC Client. Affected files are
3202 irssi/src/fe-common/silc/module-formats.[ch],
3203 irssi/src/silc/core/client_ops.c.
3205 * Use IDENTIFY command to resolve the server information in the
3206 GETKEY command instead of INFO command. Affected file
3207 lib/silcclient/command.c.
3209 * All command reply functions in the client library now calls
3210 the pending command reply callbacks even if an error has
3211 occurred. The server has done this a long time and now it was
3212 time to move the client library to this as well. Now all
3213 errors can be delivered back to the pending command reply
3214 callbacks if necessary. Affected files are
3215 lib/silcclient/command[_reply].[ch].
3217 * Change the nickname on disconnection back to the username
3218 because in reconnect the server will enforce it to it anyway.
3219 Affected file irssi/src/silc/core/silc-servers.c.
3221 * Fixed a config file parsing bug in the Irssi SILC client.
3222 Affected file irssi/src/silc/core/clientconfig.c.
3224 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3226 * When printing the channel mode on JOIN, verify that the
3227 channel key and channel's HMAC are valid. Affected file
3228 irssi/src/silc/core/client_ops.c.
3230 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3232 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
3233 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
3234 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
3236 * Removed channel key rekey task deleting from the function
3237 silc_server_save_channel_key. Affected file silcd/server.c.
3238 Added explicit timeout task context instead that is used to
3239 delete the task if we are registering a new task before the
3240 new task has elapsed.
3242 * When channel key rekey occurs the client library now saves
3243 the old channel key for a short period of time (10 seconds) and
3244 is able to use it in case some is still sending channel
3245 messages encrypted with the old key after the rekey. Affected
3246 file lib/silcclient/[idlist.h|client_channel.c].
3248 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3250 * Added check to the silc_server_new_id_real to not accept
3251 new ID if it is the sender's own ID. Affected file is
3252 silcd/packet_receive.c.
3254 * Assure that we do not announce ourself or the one we've
3255 sending our announcements when we're router and are announcing
3256 servers to our primary router. Affected file silcd/server.c.
3258 * Fixed silc_server_command_identify_check_client to assemble
3259 correct WHOIS packet. It send corrupted WHOIS packet and
3260 caused problem with router to router connections. Affected
3261 file silcd/command.c.
3263 Fixed also silc_server_command_whois_check the same way
3264 as for the IDENTIFY command.
3266 * Added new SilcIDListStatus to the server in the SilcIDListData
3267 structure. The status now includes the current status of
3268 the entry (like registered, resolved etc.). Affected file
3269 silcd/idlist.[ch]. Defined a bunch of different status types
3270 as well. This replaced the old boolean registered field as well.
3272 Added resolve_cmd_ident field to the SilcClientEntry structure
3273 too so that if the entry is for example being resolved so
3274 another command may attach to the same pending command reply
3275 without requiring to resolve the same entry again. This concept
3276 should optimize the WHOIS and the IDENTIFY resolving under
3277 heavy load by taking away unnecessary resolving for entries
3278 that are being resolved already.
3280 Added support for adding multiple pending commands for one
3281 command idenfier. Affected file silcd/command[_reply].[ch].
3283 * Fixed WHOIS and IDENTIFY save to remove the cache entry
3284 before deleting the data. Otherwise the hash table will have
3285 freed data in comparison functions. Affected file is
3286 silcd/command_reply.c.
3288 * Fixed silc_idlist_replace_client_id to add the new entry to
3289 the cache with NULL nickname. Otherwise there will be invalid
3290 memory as the nickname after the nickname is freed. Affected
3291 file silcd/packet_receive.c.
3293 * Fixed the silc_idlist_get_clients_by_hash. The entries was
3294 saved into wrong slots because the previous number of entries
3295 was not taken into account. Affected file silcd/idlist.c.
3296 Fixed same thing in silc_idlist_get_clients_by_nickname too.
3298 * If we are router and we receive JOIN notify to a channel that
3299 does not have any users then notified client is marked as the
3300 channel founder, as it is it. The affected file is
3301 silcd/packet_receive.c
3303 * Added to the extended hash table API's table_del_*ext functions
3304 the destructor as argument too, so that the caller can decide
3305 which destructor to use or whether to use destructor at all.
3306 Affected file lib/silcutil/silchashtable.[ch].
3308 * Fixed ID Cache purging. It actually deleted the entries from
3309 the hash table after the data was freed. The hash table ended
3310 up comparing freed memory. The affected file is
3311 lib/silccore/silcidcache.c.
3313 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3315 * Fixed Irssi SILC client's KILL command's HELP syntax.
3317 * The USERS command now resolves the detailed user information
3318 if the userinfo field is missing. Affected file is
3319 lib/silcclient/command_reply.c.
3321 * Do not print error in silc_file_read if the read file does
3322 not exist. Just silently return NULL. Affected file is
3323 lib/silcutil/silcutil.c.
3325 * Fixed the silc_log_output to not wine about NULL filename
3326 and to not create some bogus " " filename. Affected file is
3327 lib/silcutil/silclog.c.
3329 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3331 * Fixed various printing bugs on the user interface in the
3332 Irssi SILC Client. Minor changes that were forgotten from
3335 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3337 * Fixed the configure.in.pre and the compilation and distribution
3338 environment to support the new autoconf 2.52. That version is
3339 now required to compile the CVS trunk.
3341 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3343 * Renamed function silc_parse_nickname to silc_parse_userfqdn
3344 to generally parse user@fqdn format strings. Affected file
3345 lib/silcutil/silcutil.c.
3347 * Added nickname_format and nickname_force_format fields to the
3348 SilcClientParams structure. The first one defines the format
3349 for the nicknames that the library will enforce if the receives
3350 multiple same nicknames. The second one is boolean value and
3351 can be used to force the library to always enforce the format
3352 to the nicknames regardles whether there are multiple nicknames
3353 or not. This configurable formatting was employed to flexibly
3354 support accessing multiple nicknames from the user interface.
3355 The userinterface can now set the nicknames to what ever format
3356 they prefer. Affected file lib/silcclient/silcapi.h.
3358 Added function silc_client_nickname_format to the file
3359 lib/silcclient/idlist.c. It performs the nickname formatting.
3361 Added new field `hostname´ to the SilcClientEntry context.
3362 It holds the hostname of the client. Affected file is
3363 lib/silcclient/idlist.h.
3365 * Irssi SILC Client sets the nicknames in nick@hostn format.
3366 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
3367 irssi/src/silc/core/silc-core.c.
3369 The WHOIS printing now also shows both the real nickname and
3370 the formatted nickname so that user knows how to access the
3371 user if there are multiple same nicknames cached. Affected
3372 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
3373 printing formatting too to take the hostname now as a separate
3374 argument. The Affected file is
3375 irssi/src/fe-common/silc/modules-formats.[ch].
3377 * Changed the silc_client_get_clients_local to accept the formatted
3378 nickname as argument. It accepts the real nickname too but the
3379 formatted nickname can be used to find the true entry from
3380 multiple entries. Affected file lib/silcclient/silcapi.h and
3381 lib/silcclient/idlist.c.
3383 * Added nickname_format_parse field to the SilcClientParams.
3384 It is a callback function provided by the application to parse
3385 the nickname out of the formatted nickname string. The library
3386 calls it to get the nickname from the formatted string. Since
3387 the application generally knows better the format of the nickname
3388 string it parses it instead of the library, even though library
3389 encodes the formatted string. If the callback function is not
3390 provided then the library will use the string as is. The
3391 affected file is lib/silcclient/silcapi.h.
3393 * All the nickname strings passed to the client library in
3394 commands are now expected to be formatted nickname strings.
3395 If the command does not support the formatted nickname string
3396 it will assume that the sent string is the actual nickname.
3397 Affected file lib/silcclient/command.c.
3399 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3401 * Added public key authentication support to OPER and SILCOPER
3402 commands in the client library. Affected file is
3403 lib/silcclient/command.c.
3405 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3407 * Changed the get_auth_methdod client operation to be asynchronous.
3408 It can be async if the application resolves the authentication
3409 method from the server during the negotiation. Added new
3410 SilcGetAuthMeth completion callback that the application will
3411 call after resolving the authentication method.
3413 Added function silc_client_request_authentication_method that
3414 the application can use to resolve the authentication method
3415 from the server. Added also SilcConnectionAuthRequest callback
3416 that the library will call after the server has replied. The
3417 application can call this function if it does not know the
3418 current authentication method.
3420 Affected files are lib/silcclient/client.c and
3421 lib/silcclient/silcapi.h.
3423 * The Irssi SILC client now automatically resolves the authentication
3424 method incase any configuration information is not present (and
3425 currently there never is). The affected file is
3426 irssi/src/silc/core/client_ops.c.
3428 * Fixed public key authentication from the client library.
3429 Affected file lib/silcclient/protocol.c. Changed also the
3430 protocol specification about the public key authentication in
3431 the connection authentication protocol. The actual data to be
3432 signed is now computed with a hash function before signing.
3434 * Fixed the public key authentication from the server as well.
3435 Affected file silcd/protocol.c.
3437 * Removed the mlock()'s from the memory allocation routines.
3438 Affected file lib/silcutil/silcmemory.c. The ./configure does
3439 not check anymore for the mlock(). Affected file is
3442 * Fixed USERS command in server to allow the execution of the
3443 command for private and secret channels if the client sending
3444 the command is on the channel. Affected file silcd/command.c.
3446 * Fixed silc_client_get_clients_local to return the clients
3447 count correctly. It could return wrong value. Affected file
3448 lib/silcclient/idlist.c.
3450 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3452 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
3453 types. The assembler optimizations seemed not to like 64-bit
3454 data types. The assmebler optimizations thus are now enabled
3455 also for BSD systems as opposed to only enable them for Linux.
3457 * Do not check for threads at all on BSD systems. Affected
3458 file configure.in.pre.
3460 * Removed -n and -h options from the Irssi SILC Client since
3461 they are not used in silc.
3463 * Fixed the prime generation to assure that the first digit
3464 of the generated random number is not zero since our conversion
3465 routines does not like number strings that starts with zero
3466 digit. If zero digit is seen the random number is regenerated.
3467 This caused some corrupted RSA keys when the zero first digit
3468 was met. Affected file lib/silcmath/silcprimegen.c.
3470 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3472 * Fixed WIN32 configuration in the ./configure script.
3473 Fixed to include xti.h on environments that has it.
3474 Patches by Carsten Ilchmann and andrew.
3476 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3478 * Changed the silc_id_create_client_id to be collision
3479 resistant. It is now assured that there cannot be created
3480 two same client ID's. I suspect that some weird bugs in
3481 the server were actually caused by duplicate Client IDs.
3482 Affected file silcd/serverid.[ch]. A router receiving
3483 new ID now also assures and informs the sending server
3484 if the ID caused collision.
3486 * Changed the silc_id_create_channel_id to also assure that
3487 there are no collisions.
3489 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3491 * Statement about ignoring the Mutual Authentication flag when
3492 performing rekey with PFS was a bit misleading. It is ignored
3493 if it was set in the initial negotiation, it cannot be even
3494 set in the rekey. Fixed in the ke-auth draft. Started the
3495 new versions of the protocol drafts in the doc/.
3497 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3499 * Fixed a bug in silc_client_command_identify_save when saving
3500 new channel information. The channel name was no duplicated
3501 and caused crash on exit. Affected file is
3502 lib/silcclient/command_reply.c.
3504 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3506 * Fixed the getkey command handling in the server. Send just
3507 empty OK reply to the sender if the key could not be fetched
3508 (but everything else was ok, like the key just was not available).
3509 Changed the public key parameter to optional in the protocol
3510 specs so that empty OK reply can be sent. Affected file
3513 Added a message to Irssi SILC client to tell to user if the
3514 server did not return a public key.
3516 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3518 * Fixed a channel key regeneration bug. It registered new
3519 timeout tasks exponentially until all system resources were
3520 used. Affected file silcd/server.c.
3522 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3524 * Added the SILC Document generator to the scripts/silcdoc.
3525 It can be used to generate the Toolkit Reference Manual out
3526 of the source tree. Internally it will also use the RoboDoc
3527 generator now imported in util/robodoc.
3529 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3531 * Added couple of return's in rekey protocol if error orccurred
3532 during the protocol. The execution must be terminated.
3533 Affected file silcd/protocol.c. Also, terminate the protocol
3534 always with timeout.
3536 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3538 * The client's Client ID was created initally from the wrong
3539 nickname (it could have been in format nick@host) in the
3540 silc_server_new_client. Affected file silcd/packet_receive.c
3542 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3544 * Added some SILC_LOG_ERROR's to various error conditions
3545 if client could not be added to ID cache. Affected files
3546 silcd/packet_receive.c and silcd/server.c.
3548 * When client's sock->user_data is freed, NULL also the
3549 client->router and client->connection pointers. Added check
3550 for these pointers being NULL to various places around the
3551 code. Affected file silcd/server.c.
3553 * Added client->data.registered == TRUE checks to various
3554 places around the code to assure that unregistered client's
3555 are not handled when it is not allowed. Affected file
3558 * Added `bool registered' fields to all
3559 silc_idlist_[server|client]_get_* routines to indicate whether
3560 the fetched client needs to be registered or not. Affected
3561 file silcd/idlist.[ch].
3563 * Add your own entry as registered to the ID cache in the
3564 server. Affected file server.c.
3566 * Fixed a bug in silc_server_new_server. The SilcServer was
3567 set as the new server's context instead of SilcServerEntry.
3568 This naturally caused some weird bugs.
3570 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3572 * Do not delete the channel rekey task when adding it
3573 for in silc_server_create_channel_key.
3575 * Changed the silc_server_create_channel_key to return
3576 TRUE or FALSE to indicate the success of the channel key
3579 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3581 * Fixed MSVC++ project files and added missing files to
3582 Makefiles under win32/.
3584 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3586 * Do not add TCP_NODELAY flag if the operating system
3587 does not have it defined. Affected files are
3588 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3590 * Fixed buffer overflow from Irssi SILC Client. Affected
3591 file irssi/src/fe-common/core/themes.c.
3593 * Fixed double free in client library in the file
3594 lib/silcclient/client.c when disconnecting from server.
3596 * Applied double free patch from cras to Irssi SILC client.
3597 Affected files irssi/src/core/[modules/expandos].c
3599 * Fixed the disconnection handling to Irssi SILC Client.
3600 The application must call silc_client_close_connection
3601 in ops->connect client operation in case of failure of
3602 the connection. Affected file is
3603 irssi/src/silc/core/client_ops.c.
3605 * Do not set sock->protocol to NULL in the function
3606 silc_client_close_connection after executing the protocol's
3607 final callback since the sock might not be valid anymore.
3608 Affected file lib/silcclient/client.c.
3610 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3612 * Do not enable SILC_THREADS if the linking with libpthread
3613 did not happen. Affected file configure.in.pre.
3615 * Added notion to protocol specification that server must
3616 verify the sent authentication payload with CMODE when
3617 setting the channel founder key. Implemented it to the
3618 server. Affected file silcd/command.c.
3620 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3622 * Added _EXTRA_DIST SILC distribution variable to the
3623 distributions file. It is used to conditionally add extra
3624 files or directories to the specific distribution. Affected
3625 files ./prepare, Makefile.am.pre and distributions.
3627 Removed the `_' from the start of the distribution names.
3630 * Added README.WIN32 for instructions to compile the Toolkit
3633 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3635 * Fixed a double free in disconnection in the server. Affected
3636 file is silcd/server.c.
3638 * Fixed the lib/silcske/groups.c to work now also with GMP
3639 MP library. The string conversion did not work when using
3640 specific base and the base is indicated in the string as well.
3642 * Created win32/ directory which now includes MSVC++ specific
3643 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3644 It will appear only in the toolkit distribution
3646 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3648 * Changed the key material distribution function in case when
3649 the hash output is too short. The data is now concatenated
3650 a bit differently than it used to. Made the change to the
3651 SKE protocol specification.
3653 * Added better GMP detection to configure.in.pre. A patch
3656 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3658 * Fixed a minor bug in SKE that might cause some problem on
3659 some platforms. Affected file lib/silcske/silcske.c.
3661 * Added the cookie checking for initiator in the SKE. It checks
3662 that the responder returns the sent cookie unmodified. The
3663 affected file is lib/silcske/silcske.c. Added new SKE
3664 error type INVALID_COOKIE that can be sent during the
3665 negotiation. Fixed some memory leaks as well.
3667 * Added the "invalid cookie" error message to Irssi SILC client's
3670 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3672 * Added `task_max' field to the SilcClientParams to indicate
3673 the maximum tasks the scheduler can handle. If set to zero,
3674 default values are used. Affected file lib/silcclient/silcapi.h.
3676 * Fixed memory leaks in silc_client_close_connection. Affected
3677 file lib/silcclient/client.c.
3679 * Added silc_client_del_client_entry to client library to free
3680 all memory of given client entry. Affected file is
3681 lib/silcclient/idlist.[ch].
3683 * Added new functions silc_client_del_channel and
3684 silc_client_del_server to delete channel and server entries.
3685 Affected file lib/silcclient/[silcapi.h/idlist.c].
3687 * Removed silc_client_del_client_by_id from silcapi.h.
3689 * Fixed the INFO command to return the server's own info
3690 correctly when querying by Server ID. Affected file is
3693 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3695 * Removed the non-blocking settings in WIN32 code in the
3696 silc_sock_[read/write] and added SleepEx instead. Affected
3697 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3698 of input data is now checked with FIONREAD and ioctlsocket.
3700 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3702 * Call silc_schedule_task_del_by_context in the
3703 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3704 Affected file lib/silccore/silcprotocol.c.
3706 * Call silc_protocol_cancel for active protocols in the
3707 silc_server_close_connection if the funtion
3708 silc_server_free_sock_user_data has not been called.
3709 Affected file silcd/server.c.
3711 * Generic tasks cannot be deleted using the del_by_fd
3712 task deleting function since generic tasks does not match
3713 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3715 * Added a notion to SILCOPER help file that the SILCOPER works
3716 only on router server, not on normal server.
3718 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3720 * Added for WIN32 support for the new scheduler as well.
3721 Affected file lib/silcutil/win32/silcwin32schedule.c.
3723 * Fixed the SHA1 implementation to work on various platforms.
3725 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3727 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3728 API. It is part of the scheduler now. Everything else is
3729 as previously but some functions has changed their names.
3730 Checkout the lib/silcutil/silcschedule.h for the interface.
3731 Updated all applications to use the new interface. Affected
3732 files are lib/silcutil/silcschedule.[ch].
3734 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3736 * Found a bug in the SKE implementation. The HASH value,
3737 specified by the protocol, was not computed correctly. The
3738 public key of the responder was not added to the computation
3739 even though it is mandatory. Affected file lib/silcske/silcske.c.
3740 This unfortunately causes incompatibilities with older
3741 clients and servers.
3743 * Added WIN32 specific network init and uninit functions:
3744 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3745 the Winsock2. Affected file lib/silcutil/silcnet.h and
3746 lib/silcutil/win32/silcwin32net.c.
3748 * Set the socket always to nonblocking mode on WIN32 after
3749 reading data or writing data. Affected file is
3750 lib/silcutil/win32/silcwin32sockconn.c.
3752 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3754 * Fixed various compilation problems under WIN32. Affected
3755 files lib/silcutil/win32/silcwin32thread.c and
3756 lib/silcutil/win32/silcwin32schedule.c.
3758 * Removed all _internal.h #includes from public header
3759 files. Internal headers must never be included from
3762 Removed also the lib/silcske/payload_internal.h file.
3764 * All include files that may be needed (public and some others
3765 included by the public headers) by application developers are
3766 now copied to the ./includes directory. It does not copy any
3767 internal headers. Affected file Makefile.defines.pre and all
3768 Makefile.am's under lib/ and subdirs.
3770 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3772 * Do not change the ~/.silc directory's permissions automatically.
3773 Affected file irssi/src/silc/core/clientutil.c.
3775 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3777 * Do not cancel the protocol in silc_server_close_connection
3778 it might cause recursion. Now cancelled in the function
3779 silc_server_free_sock_user_data. Affected file silcd/server.c.
3781 * Fixed the silc_server_remove_clients_by_server to regenerate
3782 the channel keys correctly finally. Added also new function
3783 silc_server_remove_clients_channels to actually do it.
3784 Affected file silcd/server.c.
3786 * Fixed the silc_server_new_channel to not crash by giving
3787 wrong router to the new channel. Affected file is
3788 silcd/packet_receive.c.
3790 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3792 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3793 which is given as argument to the silc_client_alloc now.
3794 It can be used to configure the client and set various parameters
3795 that affect the function of the client.
3797 * The USERS command in server did not check whether the channel
3798 is private or secret. Affected file silcd/command.c.
3800 * Added new argument to the USERS command in protocol specification.
3801 The USERS command now can take the channel name as argument
3802 as well. Added support for this in client and server and
3803 updated the protocol specs.
3805 * Completed the GETKEY command in client. It can be now used
3806 to fetch also servers public key not only some clients.
3807 Affected files lib/silcclient/command[_reply].c.
3809 * Added silc_client_get_server to return server entry by the
3810 server name. Affected files lib/silcclient/silcapi.h and
3813 * Redefined the IDENTIFY command in protocol specification to be
3814 more generic. It now can be used to query information about
3815 any entity in the SILC Network, including clients, servers and
3816 channels. The query may be based either the entity's name
3817 or the ID. Added support for this in both client and server.
3819 Affected files silcd/command.c and lib/silcclient/command.c
3820 and command_reply.c.
3822 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3823 the _from_client and _from_server functions. Affected file
3826 * Added silc_client_get_channel_by_id_resolve to the file
3827 lib/silcclient/silcapi.h to resolve channel information by
3828 its ID. Added also silc_client_get_channel_by_id that
3829 does not resolve it from the server.
3831 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3833 * Added SilcServerEntry context into the client library
3834 to represent one server. The INFO command now allocates
3835 these to save the resolved server info. For now on the
3836 client library will also keep information about servers,
3837 connected and resolved with INFO.
3839 The INFO command now allocates the SilcServerEntry context
3840 and saves the server info there. The COMMAND_REPLY in
3841 the INFO now returns the parameters to application in
3842 same order as defined in the protocol specification.
3844 The entries are cached in the client->server_cache.
3846 * The INFO command is now issued after received the Client ID
3847 from the server. Affected file lib/silcclient/client.c.
3849 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3850 to the application as the mode changer might be server.
3851 It is guaranteed that NULL is not returned anymore to the
3852 application. Affected file lib/silcclient/client_notify.c.
3854 The ID Type is now also passed to the application so that
3855 it can check whether the returned entry is SilcClientEntry
3858 Added new function silc_client_get_server_by_id to return
3859 the server entry by ID. Affected files are the
3860 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3862 * Do not create the channel in the Irssi SILC Client when issuing
3863 the JOIN command but when received the sucessful JOIN command
3864 reply. Otherwise the channel might get created even though we
3865 could not join it. The Affected file is
3866 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3868 * Fixed a channel joining bug in router. The router must also
3869 check the channel modes, invite and ban lists etc. when serving
3870 the JOIN command sent by normal server. Affected file is
3871 silcd/command.c. The router now resolves the client's
3872 information from the server who sent the JOIN command if it
3873 does not know it, and processes the JOIN command only after
3876 * Changed the SilcCommandCb to take new argument; void *context2.
3877 Affected file lib/silccore/silccommand.h
3879 The second argument in the command callbacks in the server now
3880 includes the SilcServerCommandReplyContext if the command was
3881 called as pending command callback from the command reply.
3882 Otherwise it is NULL. When called as pending the status of the
3883 command reply will be checked and if it was erronous the
3884 error will be sent to the original sender of the command.
3885 This way the client always receives the error messages even
3886 though the server was actually the one who received the error
3887 when it resent the command to router, for example. Affected
3888 files silcd/command[_reply].[ch].
3890 * Fixed sending WHOWAS command's error message to client if
3891 the requested client could not be found. It was missing.
3894 * Changed the CMODE and CUMODE commands reply arguments in the
3895 protocol specification. The Channel ID is now sent in both
3896 of the commands to identify the channel. Implemented this
3897 new feature to the client and server. Affected files
3898 lib/silcclient/command_reply.c and silcd/command.c.
3900 * Made better checks for invite and ban lists in the JOIN
3901 command in server. Affected file silcd/command.c.
3903 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3905 * The server now performs the incoming host IP/DNS lookup
3906 using the silc_socket_host_lookup and thus does not block
3907 the server anymore. Affected file silcd/server.c.
3909 * Completed the multi-thread support for SILC Scheduler in
3910 the lib/silcutil/silcschedule.c.
3912 * Fixed the configure.in.pre to detect the pthread correctly
3915 * Fixed a deadlock in silc_task_queue_wakeup in the file
3916 lib/silcutil/silctask.c.
3918 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3920 * Added new function silc_schedule_wakeup that is used in
3921 multi-threaded environment to wakeup the main thread's
3922 schduler. It needs to be used when a thread adds a new task
3923 or removes a task from task queues. After waking up, the
3924 scheduler will detect the task queue changes. If threads
3925 support is not compiled in this function has no effect.
3926 Implemented the wakeup mechanism to both Unix and WIN32
3927 systems. Affected files are lib/silcutil/silcschedule.[ch],
3928 lib/silcutil/unix/silcunixschedule.c and the
3929 lib/silcutil/win32/silcwin32schedule.c.
3931 * Added new function silc_task_queue_wakeup to wakeup the
3932 scheduler by the specified task queue. Affected file
3933 lib/silcutil/silctask.[ch].
3935 * The silc_socket_host_lookup_start now wakes up the scheduler
3936 after adding the timeout task. Affected file is
3937 lib/silcutil/silcsockconn.c.
3939 * The silc_socket_host_lookup is synchronous now if the threads
3940 support is not compiled in. However, the callback is still
3941 called asyncronously through the scheduler, anyway. Affected
3942 file lib/silcutil/silcsockconn.c.
3944 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3946 * Added new function silc_socket_host_lookup to perform
3947 asynchronous IP and FQDN lookups for the socket connection.
3948 Affected files lib/silcutil/silcsockconn.[ch].
3950 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3952 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3953 that may or may not compile the mutex support in.
3955 Changed the silc_mutex_alloc interface. It allocates the
3956 mutex now to the sent pointer and returns TRUE or FALSE.
3958 Affected file lib/silcutil/silcmutex.h.
3960 * Wrote the SILC Task Queue interface to support multi-threads.
3961 Affected file lib/silcutil/silctask.[ch].
3963 * Wrote the SILC Scheduler to support multi-threads. Affected
3964 file lib/silcutil/silcschedule.c.
3966 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3968 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3969 in lib/silcutil/win32/.
3971 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3973 * Defined SILC Mutex API and SILC Thread API and implemented
3974 them for Unix. Affected files are
3975 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3976 lib/silcutil/unix/silcunixmutex.c and
3977 lib/silcutil/unix/silcunixthread.c.
3979 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3981 * Fixed the silc_server_remove_clients_by_server's channel
3982 key re-generation. The hash table handling was incorrect
3983 and would not work with many channels. Affected file is
3986 * Fixed some memory leaks around the server code.
3988 * Rewrote the silc_server_get_users_on_channel to support IPv6
3989 based Client ID's. Affected file silcd/server.c.
3991 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3992 specification. However, a separate document must be written
3993 to define the detailed signing procedure and the payload
3994 associated with the flag. Defined the flag to the
3995 lib/silccore/silcchannel.h as well.
3997 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3999 * Changed the dynamic tables to static size tables in the
4000 lib/silccrypt/silchmac.c.
4002 * Removed GCC dependencies from the code. A patch by cras.
4004 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4006 * Do not show the error "Error receiving packet bla bla"
4007 in server if it really was not an error (-2 means that reading
4008 is pending). Affected file silcd/server.c.
4010 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4012 * Fixed a possible crash in silc_server_remove_clients_by_server
4013 in silcd/server.c. Fixed there also some memory leaks.
4015 * Fixed the silc_idlist_replace_client_id. It could replace
4016 wrong key in the hash table. Affected file silcd/idlist.c.
4018 * Do not check whether there are global users on the channel
4019 if the channel->global_users is FALSE. Affected functions
4020 silc_server_remove_from_one_channel and
4021 silc_server_remove_from_channels in silcd/server.c. Also,
4022 do not check if the removed client is local as we can be
4023 sure that global client was not removed from the channel
4024 and checking for global users is not needed.
4026 * The silc_server_remove_clients_by_server now re-generates
4027 the channel keys correctly for those channels that had
4028 clients removed from them. Affected file silcd/server.c.
4030 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4032 * Found the reason of random crashes in the server. We weren't
4033 ignoring the SIGPIPE signal (which can be sent in write())
4034 and it crashed the server. Affected file silcd/silcd.c.
4036 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4038 * Assure that sock->user_data is not NULL in the function
4039 silc_server_packet_send in silcd/packet_send.c.
4041 * Disconnect the remote connection if it could not be added
4042 to any ID lists in the server. The affected file is
4045 * Check in silc_server_packet_send[_real/dest] that the
4046 socket is not disconnecting and ignore the data if it is.
4047 Affected file silcd/packet_send.c.
4049 * Define inline to __inline on native WIN32 compilation.
4050 Affected file includes/silcwin32.h.
4052 * Added some explicit type casts for inline code since MSVC
4053 require them. Affected files lib/silcutil/silcbuffer.h,
4054 lib/trq/silcdlist.h and lib/trq/silclist.h.
4056 * Print warning in log files from now on if the packet
4057 decryption fails. Affected file silcd/server.c.
4059 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4061 * Changed the `say' client operation's interface to accept
4062 new `type' argument to indicate the type of the message sent
4063 by the library. The application may filter the library's
4064 messages according the type. The affected file is the
4065 lib/silcclient/silcapi.h.
4067 * Added two new functions to lib/silcclient/silcapi.h:
4068 silc_client_del_client and silc_client_del_client_by_id.
4069 Affected file lib/silcclient/idlist.c.
4071 * Moved the clientincludes.h from includes/ to silc/ and
4072 serverincludes.h from includes/ to silcd/.
4074 * The modes for the CMODE and CUMODE are now passed as
4075 uint32 for application with COMMAND_REPLY. The affected
4076 file is lib/silcclient/command_reply.c.
4078 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4080 * /WHOIS without arguments shows client's own information.
4081 Affected file lib/silcclient/command.c.
4083 * Changed PING to not accept any arguments. The specs
4084 says that client can ping only the connected server so
4085 requiring an argument is not needed. Affected file is
4086 lib/silcclient/command.c.
4088 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4090 * Fixed a fatal bug in private message sending and reception
4091 encryption and decryption when using private message keys.
4092 The implementation was incorrect and did not follow the
4093 specification. It causd that some of the message were
4094 lost since it did not use the sending and receiving keys
4095 as the protocol suggests. This has been fixed and will cause
4096 incompatibilities with older clients when sending private
4097 message encrypted with private message keys. Affected files
4098 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
4099 and various other in Irssi SILC Client.
4101 Added `responder' boolean argument to the functions
4102 silc_client_add_private_message_key[_ske] to indicate when
4103 the key is added as responder or initiator of the key
4106 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4108 * Removed the silc_ske_check_version function and created
4109 a SilcSKECheckVersion callback. Added also a function
4110 silc_ske_set_callbacks that is now used to set all SKE
4111 callbacks. The callback functions are not given to
4112 the SKE functions anymore, but this function is used to
4115 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
4117 * Added `silc_version' argument to the silc_client_alloc
4118 to define the version of the application for the library.
4119 The library will use the version string to compare it
4120 against the remote host's (usually a server) version
4121 string. Affected file lib/silcclient/silcapi.h
4123 * Added the KE protocol context to Key Agreement context
4124 in client library so that we can abort the SKE if it
4125 is in process when we get timeout. Affected file is
4126 lib/silcclient/client_keyagr.c.
4128 * Do not resolve the client ID forever if it returns in the
4129 first time that such client does not exist. This was done
4130 for example with private message. Affected file is
4131 lib/silcclient/client_prvmsg.c.
4133 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4135 * Do not add regex.h for WIN32. The affected file
4136 includes/silcincludes.h.
4138 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
4139 not work yet 100%. It generates the DLL's automatically
4140 when compiling with --with-win32 under cygwin.
4142 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4144 * lib/contrib/regex.c is not compiled on WIN32.
4146 * Added silc_net_get_socket_opt function to the
4147 lib/silcutil/silcnet.h.
4149 * Added includes/silcwin32.h for WIN32 specific includes
4152 * Do not use ptime structure or any of the posix process
4153 functions on WIN32 in lib/silccrypt/silrng.c.
4155 * Added silc_gettimeofday to provide generic function
4156 for struct timeval on all platforms. Added the function
4157 to lib/silcutil/silcutil.h.
4159 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4161 * Moved the lib/silccore/silcsockconn.[ch] to the utility
4162 library as they clearly belong there. As a plus side we
4163 can make the actual socket connection routines platform
4166 Added also new generic function silc_socket_read and
4167 silc_socket_write (that used to be silc_packet_[read/write].
4168 The implementation of these are platform specific.
4170 * Added WIN32 specific routines of silc_socket_[read/write]
4171 to lib/silcutil/win32/silcwin32sockconn.c.
4173 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4175 * Added preliminary support for native WIN32 compilation under
4176 cygwin (using the -mno-cygwin option for GCC) to the
4177 ./configure.in.pre. The --with-win32 now prepares the
4178 compilation for native WIN32.
4180 * Rewrote the SILC Scheduler interface in the file
4181 lib/silcutil/silcschedule.h. The scheduler is now context
4182 based and does not have anymore any global static scheduler.
4183 Moved the Unix scheduler to the lib/silcutil/unix/ directory
4184 and created lib/silcutil/win32 directory for WIN32 based
4187 * Added Unix specific network routines to the
4188 lib/silcutil/unix/silcunixnet.c and the old
4189 lib/silcutil/silcnet.c includes now only generic routines.
4191 Added WIN32 specific network routines to the
4192 lib/silcutil/win32/silcwin32net.c.
4194 * Added Unix specific utility functions from the
4195 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
4197 * Added WIN32 SILC Scheduler to the file
4198 lib/silcutil/win32/silcwin32schedule.c. The code is of course
4201 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4203 * Do not handle JOIN notify in the server if the target client
4204 is not registered (idata->registered == FALSE). The affected
4205 file is silcd/packet_receive.c.
4207 * Update the nickrec->founder in event_cumode in the Irssi SILC
4208 client. Affected file irssi/src/silc/core/silc-channels.c.
4210 * Fixed the CUMODE_CHANGE notify handling in the server when
4211 server and router are announcing their clients on channels.
4212 Now the mode changes are saved and notified correctly. The
4213 affected file is /silcd/packet_receive.c.
4215 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
4216 They really did not replace the cache entry in the ID Cache.
4217 Now they do that. Affected file silcd/idlist.c.
4219 * Fixed the KICK notify handling in the Irssi SILC client to
4220 update the channel records so that the kicked client does not
4221 appear to be on the channel. The affected file is
4222 irssi/src/silc/core/silc-channels.c.
4224 * Always update the conn->current_channel when executing command
4225 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
4227 * Fixed the KILL notify handling in Irssi SILC client to remove
4228 the killed client on all channels.
4230 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4232 * Fixed the silc_parse_command_line to remove extra spaces
4233 from the start and end of the arguments. Affected file is
4234 lib/silcutil/silcutil.c.
4236 * Cancel and free any active protocol in the function
4237 silc_server_close_connection. Affected file silcd/server.c.
4239 * Cancel and free any active protocol in the function
4240 silc_client_close_connction. Affected file is
4241 lib/silcclient/client.c.
4243 * Do not execute the KILL command for clients that are in
4244 history (ie. they are not in the network). Affected file is
4247 * Fixed KILL notify handling, client does not crash anymore.
4248 Affected file irssi/src/silc/core/silc-channels.c.
4250 * Reduced the default packet buffer size from 2048 to 1024 in
4251 lib/silccore/silcpacket.c.
4253 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
4254 counter to the SKE context that is incresed when the SKE library
4255 performs async operation outside the library. If the outside
4256 process frees the SKE context and FREED status will be set
4257 and the library will detect after the sync operation that the
4258 libary is freed. The affected files are
4259 lib/silcske/silcske[_status].[ch].
4261 * Resolve the client entry information in the function
4262 silc_client_channel_message to assure that NULL pointer is not
4263 passed as client entry to the application. */
4265 * Fixed the task timeout calculation to assure that there is
4266 never negative timeouts. The affected file is
4267 lib/silcutil/silcschedule.c.
4269 * Fixed the channel user mode notification sending in server.
4270 It was sent point-to-point to the router (or to server by router)
4271 but it needs to be destined to a channel. The routines now
4272 supports sending the channel user mode notifys to the channels
4273 when announcing clients and channels. Affected files are
4274 silcd/server.c and silcd/packet_receive.c.
4276 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
4277 It did not actually replace the old channel entry in the cache.
4278 Affected file lib/silcclient/client_notify.c.
4280 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4282 * Fixed a possible crash in silc_packet_send_prepare. It now
4283 assures always that there is enough space in the buffer and
4284 at the tail area of the buffer (for MAC).
4286 Fixed the inbound buffer reallocation in silc_packet_read.
4287 It was old code and did not handle the reallocation correctly.
4290 The affected file is lib/silccore/silcpacket.c.
4292 * Fixed buffer overflow in silc_parse_nickname in the file
4293 lib/silcutil/silcutil.c.
4295 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4297 * make install generates new server keys only if there is not
4300 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4302 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
4303 Added check that if the NOREPLY is set then we will not send
4304 the away message. This avoids infinite loop of away messages
4305 if both clients are away. The affected file is
4306 lib/silcclient/client_prvmsg.c.
4308 * Fixed client crash if /NICK was given without arguments.
4309 Affected file lib/silcclient/command.c.
4311 * Server does not send the invite list in INVITE command back
4312 to the client if the list was not altered. Added this notion
4313 to the protocol spec as well. Affected file silcd/command.c.
4315 Fixed possible crash in INVITE command by checking the
4316 value of silc_server_get_client_route command.
4318 * Fixed the INVITE notify type handling. The arguments are now
4319 taken in correct order and client does not crash. The affected
4320 file is irssi/src/silc/core/silc-channels.c.
4322 Removed the "Inviting xxx to channel" message from the
4323 client library away and let the application handle it.
4324 Affected file lib/silcclient/command.c. Added that message
4325 to Irssi SILC client's message formats.
4327 * Fixed CMODE command crash in client. It now checks the
4328 amount of arguments correctly and does not crash. The affected
4329 file is lib/silcclient/command.c.
4331 * Do not create new channel automatically in silc_channels_join
4332 but check whether the channel by that name already exists.
4333 Affected file irssi/silc/core/silc-channels.c.
4335 * Do not send the SERVER_SIGNOFF to router if the disconnected
4336 entity was the router. Affected file silcd/server.c.
4338 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
4339 SILC client as it was missing from there.
4341 Added the handling of the KICK notify to the Irssi SILC client
4342 as it was missing. Added "you have been kicked" message to
4343 Irssi SILC client's message modules formats.
4345 Added the handing of the KILL notify to the Irssi SILC client
4346 as it was missing. Added the kill message module formats
4349 The affected file is irssi/src/silc/core/silc-channels.c.
4351 * The router did not save the channel mode the server announced.
4352 Affected file silcd/packet_receive.c.
4354 * Fixed a possible crash in INFO command in server. If the
4355 server did not provide the server info it crashed. Affected
4356 file silcd/command.c.
4358 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4360 * Fixed the GETKEY command in the server to check also the
4361 global list. Otherwise the GETKEY would not work correctly
4362 in normal SILC server. Affected file silcd/command.c.
4364 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4366 * Fixed GETKEY crash, it crashed if the command did not succseed.
4368 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4370 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
4371 is now real and not just an macro interface to GMP.
4373 Removed the entire GMP from the source tree and imported new
4374 NSS MPI library instead. Reason for removing GMP is that it is
4375 extremely large and compiles extremely slow. The NSS MPI
4376 is only a few files and compiles in less than 10 seconds.
4377 The speed is also about the same as GMP. The MPI is imported
4378 to lib/silcmath/mpi.
4380 If the system has GMP installed we will still use the GMP.
4381 If it is not then the NSS MPI will be compiled.
4383 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4385 * Merged a long nickname (127 characters long) crash bugfix from
4386 Irssi CVS tree. Affected file irssi/src/core/misc.c.
4388 * Merged a freed memory reference bugfix from Irssi CVS tree.
4389 Affected file irssi/src/core/commands.c.
4391 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4393 * Added the server's public key sving and verification to the
4394 server when performing the SKE. This was missing and the
4395 remote server's (or router's) public key was accepted without
4396 checking whether we have it previously or trust it at all.
4397 Affected file silcd/protocol.c.
4399 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4401 * Check in the silc_server_timeout_remote if protocol is active
4402 and make sure that the protocol's final callback is called so
4403 that all memory if freed. Affected file silcd/server.c.
4405 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4407 * silc_server_whois_send_reply crashed the server if the nickname
4408 was 127 characters long. Affected file silcd/command.c.
4410 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4412 * Added sanity check to the silc_server_new_client. If the hostname
4413 is provided inside username then check that the provided hostname
4414 really is the same as the resolved one. If the hostname was not
4415 resolved then check it from the public key. Affected file is
4416 silcd/packet_receive.c.
4418 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
4419 if the server disconnected us and the connection is not valid
4420 anymore. Affected file irssi/src/silc/core/silc-channels.c.
4422 * Moved the silc_client_[chmode|chumode|chumode_char] away from
4423 the library to the lib/silcutil/silcutil.[ch].
4425 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4427 * Close log file after open. Affected file
4428 lib/silcutil/silclog.c.
4430 * Check whether sock == NULL in silc_client_send_packet and return
4431 if it is. Affected file lib/silcclient/silcclient.c.
4433 * Check rec->entry == NULL in the Irssi SILC Client before
4434 sending the channel message. Affecte file is
4435 irssi/src/silc/core/silc-servers.c.
4437 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4439 * Merged a splitted window bugfix from Irssi CVS tree. The
4440 affected file is irssi/src/fe-text/textbuffer-view.c.
4442 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
4443 It did not print nickname.
4445 * Improved the distributions system a bit.
4447 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4449 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
4450 irssi/src/fe-text/gui-window.c.
4452 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
4453 to in-active server. The affected file is
4454 irssi/src/silc/core/client_ops.c.
4456 * Resolve the client in USERS command reply if the entry does
4457 not have username resolved. The affected file is
4458 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
4459 command to WHOIS command to really resolve stuff. The USERS
4460 is not used any more in any critical section so WHOIS can
4461 be used even though it might be slower than IDENTIFY.
4463 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
4466 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4468 * Changed the protocol API a bit more consistent in the
4469 lib/silccore/silcprotocol.[ch].
4471 * Changed the following headers to ROBODoc format:
4473 lib/silccore/silcpayload.h
4474 lib/silccore/silcprotocol.h
4475 lib/silccore/silcsockconn.h
4477 All core library headers are now formatted.
4479 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4481 * Fixed a bug in Irssi SILC client; do not show that you are
4482 server/router operator if you really are not. Affected file is
4483 irssi/src/silc/core/client_ops.c.
4485 * Renamed silc_command_free_payload to silc_command_payload_free.
4486 Affected file lib/silccore/silccommand.h
4488 * Added silcmath.h to include the prototoypes of various routines
4489 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
4492 * Changed the following headers to ROBODoc format:
4494 lib/silccore/silcchannel.h
4495 lib/silccore/silccommand.h
4496 lib/silccore/silcid.h
4497 lib/silccore/silcidcache.h
4498 lib/silccore/silcmode.h
4499 lib/silccore/silcnotify.h
4500 lib/silccore/silcpacket.h
4501 lib/silcmath/silcmath.h
4503 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4505 * Added checking to the server code not to start the server if
4506 ciphers and stuff are not configured properly. Affected files
4507 silcd/serverconfig.[h] and silcd/server.c.
4509 * Changed the layout of the header files of the public interfaces
4510 in the SILC libraries. The new layout supports ROBODoc
4511 documentation tool (and some others) so that it is easy to create
4512 a library reference manual. All the other headers and source
4513 code must still follow the CodingStyle document. Also source
4514 code must not include these ROBODoc stuffs, only the headers.
4515 Furthermore, all public interface headers must now be named
4516 by using `silc' prefix, example: silcapi.h, silccipher.h.
4517 Some files were renamed due to this. All the other headers
4518 must not be used as public interfaces. I will update the
4519 CodingStyle document later. Changed following headers, so far:
4521 lib/silcclient/silcapi.h
4522 lib/silccore/silcauth.h
4523 lib/silccore/silcprivate.h
4524 lib/silccrypt/silcdh.h
4526 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4530 * Removed silc_client_packet_send_flush from the client library
4531 as it is not needed. Affected file lib/silcclient/client.[ch].
4533 * Added printing of message of unresolved authentication method
4534 to the Irssi SILC client. Added it to the module formats.
4535 Removed the same message from the client library.
4537 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4539 * Added new distribution feature, DISTLABEL. Every distribution
4540 can define own preprocessor label that can be used in the
4541 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
4542 file distributions, acconfig.h.pre and prepare.
4544 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4546 * Added Makefile.defines_int to include the actual definitions
4547 for Makefile.defines.in. Tested the new distribution system,
4548 created distributions and tested installation.
4550 * Added AWAY message printing to the Irssi SILC client. Added
4551 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
4553 * Added SCONNECT command to call the SILC's CONNECT command.
4554 Cannot use CONNECT directly since Irssi uses that internally.
4555 Affected file irssi/src/silc/core/silc-servers.c.
4557 Added ACTION local command. It is same as ME command but takes
4558 the channel as mandatory argument.
4560 Rewrote some of the Irssi's help files to suite for SILC
4563 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4565 * Added Makefile.defines[.in] that should for now on be included
4566 in all Makefile.am file in the source tree. That file includes
4567 all common compilation definitions for SILC source tree.
4569 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4571 * Minor changes to the ./prepare script to change the package
4572 name according the distribution name to the configure.in.
4574 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4576 * Created new distribution system. Added file `distributions'
4577 that defines all the distributions that can be created out of
4578 the SILC source tree. The ./prepare script now reads that
4579 file to determine how to prepare the distributions. The
4580 first argument to the ./prepare is the name of the distribution
4581 and second is the version of the distribution. If given
4582 without arguments it creates the default (toolkit) distribution
4583 with the default version (defined in ./prepare).
4585 All Makefile.am files that are subject to the distributions
4586 are now named as Makefile.am.pre. These are ./Makefile.am
4587 and lib/Makefile.am. Others may be changed later.
4589 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4591 * Added invite list, ban list, some key management and connection
4592 error message printing to module formats in the Irssi SILC client.
4594 * Added new silc_client_set_away_message to set the away message
4595 that is back to the person who sent private message. The
4596 affected file lib/silcclient/silcapi.h and the
4597 lib/silcclient/client_prvmsg.c.
4599 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4601 * Fixed the private message sending in the Irssi SILC client,
4602 added local command KEY to the Irssi SILC client.
4604 Added key management and key agreement message formats to the
4605 irssi/src/fe-common/silc/module-formats.[ch].
4607 Added USERS (alias WHO) printing, server/router operator
4608 indication and LIST command printing to the module formats.
4610 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4612 * Fixed channel joining notify handling, cumode notify handling
4613 from Irssi SILC client.
4615 * Added SILC specific module-formats to the Irssi SILC client so
4616 that SILC specific message hilighting, colors etc is possible.
4617 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4619 Added channel mode, channel user mode, actions, notices,
4620 whois and whowas printing to the the module-formats.c.
4622 * Fixed a bug in channel deletion in the server. The channel
4623 is not left to the cache even if the channel founder auth mode
4624 is set when there are no users anymore on the channel. Affected
4625 file silcd/server.c.
4627 * The silc_net_localhost now resolves the entire hostname including
4628 the domain name. Affected file lib/silcutil/silcnet.c.
4630 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4632 * Changed the ask_passphrase client operation to be ascynchronous.
4633 It has now a completion callback and a context that the
4634 application must call after it has got the passphrase from
4635 the user. Affected files lib/silcclient/silcapi.h,
4636 lib/silcclient/protocol.c, lib/silcclient/command.c and
4639 Added SilcAskPassphrase callback that the application calls
4640 to deliver the passphrase to the library.
4642 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4643 The public key verification and especially a certificate
4644 verification is asynchronous procedure.
4646 Added new SILC_SKE_STATUS_PENDING status to indicate the
4647 request is pending and a callback will be called to finalize
4650 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4651 indicate that remote end did not send its public key (or
4652 certificate), even though we require it. Added check for this
4653 condition in the SKE. This was a security bug, now fixed.
4655 Defined new SilcSKEVerifyCbCompletion callback that is called
4656 when the verification process is completed.
4658 The affected files lib/silcske/silcske_status.h and
4659 lib/silcske/silcske.[ch].
4661 * Changed the verify_public_key client operation to be async
4662 as well. Defined SilcVerifyPublicKey callback that is used to
4663 indicate the success of the public key verification process.
4665 Changed the server and client to use the new async client
4668 * Changed the Irssi SILC client's internal scheduler to be called
4669 twice as many times as it used to be. As a result the client
4670 should be a bit faster now. Affected file is
4671 irssi/src/silc/core/silc-core.c.
4673 * Added support to Irssi SILC client of asynchronous public key
4674 verification and passphrase inquiry. Affected file is
4675 irssi/src/silc/core/silc-core.c.
4677 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4679 * Do not say "You have left channel %s" in client library.
4680 Moved it to the application. Affected files are
4681 lib/silcclient/command.c and silc/client_ops.c.
4683 * Fixed silc_client_get_clients. Command context was not
4684 duplicated and was freed memory in the callback. Affected
4685 file lib/silcclient/idlist.c.
4687 * Do not say "you are now talking..." on JOIN command in the
4688 client library. The appliation must handle it.
4690 * Do not say ".. changed topic to" in command reply in the
4691 client libary. The application must handle it.
4693 * Fixed TOPIC command sending in the client library.
4695 * Fixed a memory leak in silc_client_command_free in the file
4696 lib/silcclient/command.c.
4698 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4700 * Imported a modified version of Irssi client to the source tree.
4701 The Irssi will be used to create a new client called
4702 Irssi SILC. Imported to irssi/.
4704 Added silc_core_init_finish function to the Irssi. Affected
4705 file irssi/configure.in.
4707 A lot changes in the Makefile.ams around the irssi tree.
4709 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4711 * Do not rehash if the new size is same as the old size of the
4712 hash table, in the silc_hash_table_rehash*. The affected file
4713 lib/silcutil/silchashtable.c.
4715 * Replaced hash_table_del_by_context calls from the server
4716 (when channel->user_list and client->channels) to the
4717 hash_table_del as it is sufficient and faster.
4719 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4721 * Added silc_hash_table_list, silc_hash_table_get and the
4722 SilcHashTableList structure to provide an alternative way to
4723 traverse the hash table. The affected files are
4724 lib/silcutil/silchashtable.[ch].
4726 * Changed the server's idlist routines to use the hash table
4727 routines to optimize the code.
4729 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4731 * Replaced the client entry's `channel' list and channel entry's
4732 `user_list' list to hash tables for optimized lookup. Changed
4733 the code to use the hash table interface around the code.
4734 Affected file lib/silcd/idlist.[ch].
4736 * Added `auto_rehash' boolean argument to the function
4737 silc_hash_table_alloc to indicate whether the hash table should
4738 auto-rehash when it thinks is appropriate time. It will
4739 increase the hash table size if the there is twice as much
4740 entries in the table than the size of the table, and will
4741 decrease the size if there are twice as less entries than
4742 the size of the table.
4744 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4746 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4748 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4750 * silc_idcache_purge_by_context deletes the entry now by context
4751 as it is supposed to do. Affected file lib/silccore/idcache.c.
4753 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4754 client is not anymore valid (WHOWAS givens the info) and not
4755 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4757 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4759 * Removed the `data' and `data_len' arguments from the ID Cache
4760 interfaces and added `name' argument. ID Cache does not handle
4761 anymore the binary data only a names associated with given ID.
4763 * When hashing a Client ID with silc_hash_id the entire ID is
4764 not hashed anymore, instead only the hash of the Client ID is
4765 hashed. This way we can access the Client ID from the cache
4766 with Client ID but with the hash of the ID (which is a hash of
4767 the nickname) as well without any difference in performance.
4769 Added also silc_idcache_find_by_id_one_ext to do one on one
4770 searching when we have the actual ID. Added also function
4771 silc_hash_client_id_compare. The affected files are
4772 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4774 * When hashing the name associated with a ID it is always done
4775 in lowercase. This way we can access the cache without worrying
4776 about case-sensitivity, even though, for example nicknames are
4779 * Fixed a bug in server with channel message sending. It put
4780 wrong ID type as destination ID. The affected file
4781 silcd/packet_send.c.
4783 * silc_idcache_del_by_context now deletes from all hash tables
4784 by context. Affected file lib/silccore/idcache.c.
4786 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4788 * Changed the client library to use the new ID Cache interface.
4789 Changes around the source tree.
4791 * Added silc_hash_table_rehash_ext to rehash with specific
4792 hash function. Affected file lib/silcutil/silchashtable.[ch].
4794 * Added silc_hash_string_compare to compare two strings in the
4795 hash table. Affected file lib/silcutil/silcutil.[ch].
4797 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4799 * Added new function silc_idcache_del_by_context into the
4800 lib/silccore/idcache.[ch].
4802 * Changed the server's ID list routines to use the new ID Cache
4803 interface. Changes around the source tree.
4805 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4807 * Added silc_hash_table_del[_by_context]_ext functions in to the
4808 lib/silcutil/silchashtable.[ch].
4810 Removed silc_hash_table_find_all* routines and added new
4811 silc_hash_table_find_foreach to replace them.
4813 Added silc_hash_table_replace_ext function as extended
4814 replacing function. Separated the simple hash table interface
4815 from the extended hash table interface in the file
4816 lib/silcutil/silchashtable.h.
4818 * Fixed minor bugs and changed it to use some of the new
4819 hash table functions in lib/silccore/idcache.c
4821 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4823 * Added new function silc_hash_table_find_all to return all keys
4824 in the hash table by the specified key. As the hash table is
4825 collision resistant it also makes it possible to have several
4826 duplicate keys in the hash table. This function may be used to
4827 find all of the keys from the hash.
4829 Added user_context arguments to the SilcHashFunction,
4830 SilcHashCompare and SilcHashDestructor to deliver user specified
4833 Added new fuctions silc_hash_table_find[_all]_ext to do
4834 extended lookup with specified hash and compare functions and
4835 specified user contexts.
4837 Added new function silc_hash_table_add_ext to add the key
4838 with specified hash function and user context.
4840 Added new function silc_hash_table_foreach to traverse all
4841 entrys in the hash table. Added SilcHashForeach callback
4844 Added new function silc_hash_table_del_by_context to delete
4845 the entry only if the context associated with the key matches.
4847 Affected files are lib/silcutil/silchashtable.[ch].
4849 * Removed silc_hash_[server/client/channel]_id and added just
4850 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4851 silc_hash_id_compare to compare two ID's using as the hash table
4852 comparison function. Added also silc_hash_data to hash
4853 binary data and silc_hash_data_compare to compare it.
4855 * Removed silc_idlist_find_client_by_hash as it is not needed
4856 anymore. Affected file silcd/idlist.[ch].
4858 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4859 to use internally the SilcHashTable. The new ID Cache is a lot
4860 faster than the old one. Some of the ID Cache interface was also
4861 rewritten and obsolete and stupid functions were removed.
4863 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4865 * Added entry_count field to the SilcHashTable to keep the number
4866 of the entries in the table. Implemented the function
4867 silc_hash_table_rehash. Added new function
4868 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4870 Fixed a minor bug in silc_hash_table_free.
4872 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4873 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4874 into the lib/silcutil/silcutil.[ch].
4876 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4878 * Implemented a collision resistant hash table into the
4879 lib/silcutil/silchashtable[ch]. See the header and the source
4880 for the SilcHashTable API.
4882 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4884 * Merged dotconf version 1.0.2 into lib/dotconf.
4886 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4888 * Do not compile anything in lib/silcsim/* if the SIM support
4889 is not enabled. The tree should now compile without problems
4892 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4894 * Compiled the SILC under cygwin. Compiled and tested briefly
4895 without problems. More tests needed. The SIMs didn't compile
4898 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4900 * Fixed possible crash in silc_get_username in the
4901 lib/silcutil/silcutil.c.
4903 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4905 * Fixed a va_arg in silc/client_ops.c.
4907 * Oops, RC5 routines were named AES and caused some problems
4908 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4910 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4912 * Added new SilcIDIP structure into the lib/silccore/id.h and
4913 replaced the old `ip' fields from all SILC ID's to that type.
4914 This is a step towards IPv6 support.
4916 The silc_id_get_len takes now the ID as an extra argument.
4917 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4918 both IPv4 and IPv6 based ID's.
4920 The affected files are lib/silccore/id.[ch] and other files
4921 around the tree using these routines.
4923 * Removed the ID length arguments in server from various
4924 silc_server_send_notify_* routines -> they are not needed
4927 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4929 * Fixed memory leak in silc_encode_pem_file in the file
4930 lib/silcutil/silcutil.c.
4932 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4934 * Check minor version as well in the SKE. Affected files are
4935 silcd/protocol.c and lib/silcclient/protocol.c.
4937 * Added --identifier option to the server so that an identifier
4938 can be when creating the public key for the server. Affected
4939 file is silcd/silcd.c.
4941 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4942 lib/silccrypt/silcpkcs.c.
4944 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4946 * Register default ciphers and stuff when using -C option with
4947 the server. Affected file sildc/silcd.c.
4949 * Put back the servers public key filename format, it is better
4950 than the new one. For now, the client keys are saved with the
4951 new filename format. The affected file silc/client_ops.c.
4953 * Implemented the Cipher API for the rest of the ciphers that
4954 did not implement it or implemented it the wrong way.
4956 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4958 * Register default ciphers and stuff when using the -S option
4959 in the client. Affected file silc/silc.c. Same also when
4960 creating new key pair with -C option.
4962 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4964 * Fixed the silc_verify_public_key client operation function to
4965 save the public keys differently. The fingerprint is now
4966 used as filename and not the hostname. This way also the
4967 client keys are saved uniquely and not with hostnames. The
4968 affected file is silc/client_ops.c.
4970 * Trimmed the silc_hash_fingerprint function to remove extra
4971 whitespaces from the end of the fingerprint. The affected
4972 file is lib/silccrypt/silchash.c.
4976 * Added silc_cipher_register_default function to register all
4977 default ciphers. It can be used when configuration files
4978 does not exist and the application does not want any specific
4979 ciphers in any specific order.
4981 The SilcDList is now used as silc_cipher_list dynamically
4982 allocated cipher list. Removed the static list all together
4983 and now all ciphers must be allocated to the dynamic list.
4984 The silc_cipher_alloc routine was changed to check only the
4987 All silc_cipher_* routines that used to return int returns
4990 The affected files lib/silccrypt/silccrypt.[ch].
4992 * The same thing was done to silc_hash_* as for silc_cipher_*
4993 routines. Affected files lib/silccrypt/silchash.[ch].
4995 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4996 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4997 Added also silc_pkcs_[un]register[_default] functions.
4998 Removed the data_context from the PKCS API.
5000 * Added silc_hmac_register_default function to register default
5001 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
5002 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
5003 to unregister all hmacs at once.
5005 * Register the default ciphers, hash functions, PKCSs and HMACs
5006 if client's configuration file does not exist. The affected
5009 * The client did not load the hash functions from the SIM
5010 modules at all. Added support for this. Affected file is
5011 silc/clientconfig.c.
5013 * When decoding public key with silc_pkcs_public_key_decode, check
5014 the supported algorithm only if PKCS are registered. Affected
5015 file lib/silccrypt/silcpkcs.c. The same was done with the
5016 silc_pkcs_private_key_decode.
5018 * Fixed the SILC List routines to keep the list always in order.
5019 It used to change the list's order when traversing the list but
5020 not it preserves the order. Affected file lib/trq/silclist.h.
5022 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5024 * Added the client library to use the SilcSocketConnection's
5025 reference counter (by silc_socket_dup) to prevent the bug that
5026 the socket object may be freed underneath async operation.
5028 * The name resolv library checking fixes in the configure.in.pre.
5031 * Created new version of the protocol drafts for future
5032 development. The -03 drafts are the ones that will be changed
5033 in the trunk now and the -02 will remain as they are.
5035 * Send list of CUMODE notifys to the router when announcing
5036 the channel users to the router. Affected file silcd/server.c.
5037 If the router receiving channel founder CUMODE for a channel
5038 that already has channel founder it will send CUMODE notify
5039 to the sender to remove the channel founder rights from the
5040 announced client. Affected file silcd/packet_receive.c.
5042 * The CUMODE notify may now use Server ID as well as the entity
5043 who changes the mode. Updated protocool specs.
5045 * Updated INSTALL and README files.
5047 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5049 * New web pages in the http://silc.pspt.fi. The pages was
5054 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5056 * Implemented the [DenyConnectin] config section in the server.
5057 Added silc_server_config_denied_conn to check whether incoming
5058 connection is denied. Affected file silcd/serverconfig.[ch].
5060 * Do not check the ports when checking the incoming configuration
5061 data if the port is 0, meaning any. Affected file is
5062 silcd/serverconfig.c.
5064 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5066 * Fixed buffer overflow in silc_string_compare in the file
5067 lib/silcutil/silcutil.c.
5069 * Fixed double free in silc_server_command_leave in the file
5072 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5074 * Fixed the version checking in the server. Affected file is
5077 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5079 * Fixed the configuration data fetching when accepting new
5080 connections in the server. Affected file silcd/server.c.
5082 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5084 * Added `sender_entry' argument to the function
5085 silc_server_packet_relay_to_channel so that we can check
5086 whether some destination actually belongs to the same route
5087 the sender belongs (ie, we must not resend the packet to the
5088 sender). Affected file silcd/packet_send.[ch].
5090 * Added `servername' field to the SilcClientEntry in the server
5091 to hold the name of the server where client is from. Affected
5092 file is silcd/idlist.h.
5094 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5096 * Moved the channel message encrypting in the router betwen
5097 router connections from silc_server_channel_message to the
5098 silc_server_packet_relay_to_channel since we want to check
5099 whether we have anybody channel before encrypting anything.
5100 Affected files silcd/packet_[receive/send].c.
5102 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5104 * Fixed the [AdminConnection] server config section to support
5105 multiple entries. Affected file silcd/serverconfig.c.
5107 * Added support into the server to check the validity of the
5108 incoming connection before executing any KE or authentication
5111 * The connection configuration is now saved to the KE and
5112 connection auth protocol contexts and not fetched anymore in
5113 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
5115 * The local hosts listenning address and port is also resolved
5116 now when starting the server. We want to have the socket object
5117 to include the real address and port for the listener. Added
5118 new function silc_net_check_local_by_sock into the files
5119 lib/silcutil/silcnet.[ch].
5121 * Fixed a broadcast bug in server -> do not broadcast if we
5124 * Fixed a routing bug. Do not route broadcast packets ever.
5125 Broadcast packets must be processed always and not routed since
5126 they may be destined to some other host than yourself and thus
5127 would get routed without no good reason. Affected file is
5130 * Added function silc_server_config_is_primary_route to check
5131 whether primary router connection has been configured (a router
5132 configuration that we are initiating). If there is not, we
5133 will assume that there is only two routers in the SILC network
5134 and we will use the incoming router connection as our primary
5135 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
5137 * Changed the order of the broadcasting. Broadcast _after_ the
5138 packet has been processed not before. Affected file is
5141 * Fixed a [ClientConnection] parsing bug. The port was never
5142 parsed correctly thus resulting to port 0. Affected file
5143 silcd/serverconfig.c.
5145 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
5146 argument and did not set the broadcast packet flag. Affected
5147 file silcd/packet_send.c. Fixed same bug in the function
5148 silc_server_send_notify as well.
5150 * If we receive NEW_ID packet for our own ID in the server, ignore
5153 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5157 * Removed the nickname from the Private Message Payload.
5158 Updated the code and the protocol specs.
5160 * Updated protocol specs for submitting to the IETF.
5162 * Tweaked the Random Number Generator a bit. Affected file
5163 lib/silccrypt/silcrng.c. Exported a new function
5164 silc_rng_[global]_add_noise which can be used to add more
5167 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5169 * Do not parse packets with different timeout when protocol
5170 is active -> may cause problem with rekey. Affected file
5173 * When server receives signoff notify it must not create
5174 new channel key if the client is on any channels since the
5175 sender of the signoff notify will create it.
5177 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5179 * Added printing of error messages during SKE protocol from the
5180 failure packet sent by server during SKE. Affected file
5183 * Removed the client's failure_callback handling with timeout
5184 and handle it immediately when received.
5186 * The SKE library returned wrong type in SUCCESS and FAILURE
5187 packets. They must be 32 bit MSB not 16 bit MSB.
5189 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5191 * Ok, rewrote the logic of the re-key and now it seems to work.
5192 I tested it on high traffic with frequent re-keys without
5193 problems. Added hmac_receive (and renamed hmac to hmac_send)
5194 in SilcClientConnection in lib/silcclient/client.h and
5195 in SilcIDListData in silcd/idlist.h. Also, removed the
5196 SilcPacketParserContext's cipher and hmac fields as they are
5197 not needed anymore and actually caused some problems when
5198 the ciphers and hmac's changed underneath the packet parser.
5200 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5202 * If re-key protocol is active then process the incoming packets
5203 synchronously since we must assure that icoming packets encrypted
5204 with the old key is processed before the new keys is set to
5205 use. This is true other packets than for REKEY packets.
5206 Affected file silcd/server.c. The same was done to client library
5207 as well, affected file lib/silcclient/client.c.
5209 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5211 * Fixed bug in client and server to accept the force send if
5212 the packet is send from silc_[server/client]_packet_process
5213 function. Otherwise the packets are never delivered, oops.
5215 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5217 * Disable force sending of packets when REKEY protocol is active.
5218 We must assure that no packet is sent directly when rekey is
5219 performed. All packets must be sent through packet queue.
5220 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
5221 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
5222 function is silc_[server/client]_packet_send_real to check
5225 * Replaced the SIM paths from example config files to
5226 /usr/local/modules. Also, make install creates now
5227 /usr/local/silc/logs directory to hold all the SILC server
5230 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

5241 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5243 * When MAC computation fails the silc_packet_decrypt returned 0
5244 even though it was supposed to return -1. Fixed this. The
5245 affected file is lib/silccore/silcpacket.c.
5247 * Do not replace the config files in /etc/silc (in make install)
5248 if they already exist. Affected file ./Makefile.am.
5250 * Do not send re-key packets immediately but through packet queue.
5251 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
5253 * Changed silc_net_check_host_by_sock to return FALSE if the
5254 IP/DNS could not be resolved. Though, it returns the IP address
5255 now even if it could not resolve it (but returns also FALSE).
5256 Affected file lib/silcutil/silcnet.[ch].
5258 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5260 * Added silc_pkcs_decode_identifier to decode the public key's
5261 identifier. Affected file lib/silccrypt/silpkcs.[ch].
5262 Added also silc_pkcs_free_identifier. Added also new context
5263 SilcPublicKeyIdentifier.
5265 * Added -S option to the silc client. It is used to dump the
5266 contents of the specified public key file.
5268 * Changed the PKCS api to return the public key length when
5269 setting the public key.
5271 * Fixed a fatal bug in the public and private key file loading.
5272 Affected file lib/silccrypt/silcpkcs.c.
5274 * Execute the packet parsing for client with zero (0) timeout
5275 if the protocol is active. Affected file silcd/server.c.
5277 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5279 * Made the key generation options to the silcd program. Added
5280 -C option, equivalent to client's option.
5282 * Added new [ServerKeys] config section to the server. It
5283 configures the server's public and private key.
5285 * Defined generic Public Key Payload into the protocol
5286 specification to send specific type of public keys and
5289 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
5290 public key or certificate.
5292 * Implemented the GETKEY command to the server and to the
5293 client library and on user interface.
5295 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5297 * Made preliminary `make install' work.
5299 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5301 * Added SilcServerRekey context into silcd/idlist.h.
5303 * Added the PFS support as defined in the specification to the
5304 SKE protocol. Affected files lib/silcske/*.c.
5306 * Added `ske_group' field to the SilcServerRekey context to hold
5307 the number of the SKE group that is used with PFS in re-key.
5308 Affected file silcd/idlist.h.
5310 * Added PFS re-key support to the server. Affected file is
5313 * Added silc_protocol_cancel to cancel execution of the next
5314 state of the protocol. Affected file is
5315 lib/silccore/silcprotocol.[ch].
5317 * Added the re-key support with and without PFS to the client
5318 library. Re-key is performed once in an hour, by default.
5320 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
5321 Added silc_client_rekey_callback and silc_client_rekey_final.
5322 Affected files are lib/silcclient/protocol.[ch] and
5323 lib/silcclient/client.[ch].
5325 * Removed the `hmac_key' and `hmac_key_len' fields from the
5326 SilcClientConnection structure; not needed. Affected file is
5327 lib/silcclient/client.h.
5331 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5333 * Do not ask whether user wants to use the negotiated private key
5334 for private messages, just use it. Affected file is
5335 silc/local_command.c.
5337 * Added `send_enc_key' and `enc_key_len' fields to the
5338 SilcIDListData structure since they are needed in the re-key
5339 phase. Affected file is silcd/idlist.[ch].
5341 * Implemented the simple re-key protocol into the server.
5342 Affected files silcd/server.c and silcd/protocol.[ch]. The
5343 re-key will be performed once in an hour, by default.
5345 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
5346 Added silc_server_rekey, silc_server_rekey_callback and
5347 silc_server_rekey_final.
5349 * Removed Tunneled flag from the protocol. Updated the code
5350 and the specifications.
5352 * Adde `pfs' field to the SilcIDListData to indicate whether
5353 the PFS is to be performed in the re-key. Affected file is
5356 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5358 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
5359 int64 of at least the xintXX size. If void * is less that 4
5360 bytes uint32 * will be used. Defined bool as boolean.
5362 * Changed _ALL_ unsigned long and unsigned int to uint32,
5363 unsgined short to uint16 in the source tree.
5365 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
5366 not handle clients that has entry->data.registered == FALSE.
5367 They are not in the network anymore. Affected file is
5370 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5372 * Implemented the sending of the SERVER_SIGNOFF notify in the
5373 server. Affected file is silcd/server.c.
5375 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
5376 Added also silc_notify_payload_encode_args into the
5377 lib/silccore/silcnotify.[ch].
5379 * Implemented ther SERVER_SIGNOFF notify handling in the server.
5380 Affected file silcd/packet_receive.c.
5382 * Implemented the SERVER_SIGNOFF notify handling in the client
5383 library. Affected file lib/silcclient/client_notify.c. Also,
5384 implemnted the printing of the SERVER_SIGNOFF info to the
5385 application. Affected file silc/client_ops.c.
5387 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
5388 if the deleting was successful. Affected file silcd/idlist.[ch].
5390 * Added support for public key authentication in the connection
5391 authentication protocol in the client library. Affected file
5392 lib/silcclient/protocol.c.
5394 * Changed the server's silc_idlist_get_clients_by_* interface
5395 to support already allocated array so that new entries may be
5396 added to pre-allocated array. Affected file silcd/idlist.[ch].
5397 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
5398 and command replies.
5400 * All command reply functions in the server now calls the
5401 pending command callback even if error occured. This way the
5402 error will be delivered to the client as well. Affected files
5403 silcd/command.c and silcd/command_reply.c.
5405 * Fixed INFO command to return local server's info if no server
5406 was provided. Affected file lib/silcclient/command.c.
5408 * Removed RESTART command for good. Updated the code and the
5411 * Rewrote parts of the task system. It is a bit simpler now.
5412 Removed unsued task priorities. The affected files are
5413 lib/silcutil/silctask.[ch].
5415 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5417 * Moved the USERS printing from the library to the application.
5418 Affected files lib/silcclient/command.c and silc/client_ops.c.
5420 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5424 * Added channel key re-key support. The re-key is perfomed
5425 only by the router and is done once in an hour. Added `rekey'
5426 field to the SilcChannelEntry in the server. Affected files
5427 silcd/server.c and silcd/idlist.h.
5429 * Added silc_task_unregister_by_context into the file
5430 lib/silcutil/silctask.[ch].
5432 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5434 * Added SILC_UMODE_GONE mode to indicate when the client is not
5435 present in the SILC network. Added also support to the local
5436 command AWAY that will set this mode. Added support of showing
5437 "xxx is gone" in WHOIS command. The USERS command shows the
5438 gone status as well.
5440 * Fixed setting server and router operator privileges in the
5441 server's UMODE command. Affected file silcd/command.c.
5443 * Merged the SKE KE1 and KE2 payloads into one payload. The
5444 new KE payload is equivalent to the old KE2 payload.
5446 Cleaned up the SKE Start Payload parsing. It now uses the
5447 simple buffer unformatting to do the parsing. A lot faster
5450 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
5451 to the SKE that is used to indicate whether both of the SKE
5452 parties should perform authentication. By default only the
5453 responder performs authentication. By setting this flag also
5454 the initiator must do authentication. By default it is unset
5455 since in normal SKE case, client to server connection, only
5456 the responder should do authentication. When doing SKE between
5457 two clients both should perform authentication. Updated the
5458 code and the protocol specs.
5460 * A little fix to IDENTIFY command in the server. Search the
5461 client first by hash not nickname. Affected file is
5464 * Fixed the silc_client_close_connection to support closing
5465 the client to client connections wihtout deleting too much
5466 data. Affected file lib/silcclient/client.c.
5468 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
5469 are received if protocol used to be active but is not anymore
5470 the application would crash due to NULL pointer dereference.
5471 Affected files silcd/server.c and lib/silcclient/client.c.
5473 * Added `hash' field to the SilcClientConnection to include
5474 the hash function negotiated in the SKE protocol.
5476 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
5477 to set the channel founder authentication data. A client can
5478 claim the founder rights later by providing the authentication
5479 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
5480 This way the channel founder can regain the channel founder
5481 privileges even it is left the channel. This works only on
5482 local server and the client must be connected to the same
5483 server to be able to regain the founder rights. Updated the
5484 protocol specs accordingly.
5486 Added support to the CMODE command in the client to set the
5487 founder auth data. Read the README to see how to set it.
5489 Added support to the CUMODE command to claim the founder
5490 rights. Read the README to see how to do it.
5492 Added support for the founder authentication to the Channel
5493 Entry in the server. Affected file silcd/idlist.h.
5495 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
5496 server's CMODE command. Affected file silcd/command.c.
5498 * Added the following new functions into lib/silccore/silcauth.[ch]:
5499 silc_auth_get_method and silc_auth_get_data.
5501 * The server now saves the remote hosts public key to the
5502 SilcIDListData pointer. Affected file silcd/protocol.c.
5504 * The normal server now does not remove the channel entry from
5505 the cache if the founder authentication data is set. It used
5506 to remove it if the founder was the last one on the channel on
5507 the server and left the channel. The auth data is saved and
5508 if the channel is re-joined later the old entry is used with
5509 the old auth data. Affected files silcd/command_reply.c and
5512 * Removed the `pkcs' field from the SilcIDListData structure
5513 in the server; it is not used. Affected file silcd/idlist.h.
5515 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5517 * Fixed packet processing on slow links. Partial packets were
5518 never re-processed because the incoming data buffer was cleared
5519 by the application. Application must not directly clear the
5520 sock->inbuf, the packet processing routines handle it. Fixed
5521 this in client library and in server.
5523 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5525 * Fixed the WHOIS and IDENTIFY send reply function to really
5526 check whether to send list or just one entry. Affected file
5529 * Cleaned up the LEAVE command's channel key distribution. The
5530 affected file silcd/command.c.
5532 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
5533 can enforce the channel mode as well. In that case the ID
5534 includes the ID of the server. The code now enforces the
5535 mode change if the router have different mode than the server.
5537 * The notify client operation with CMODE_CHANGE notify can now
5538 return NULL client_entry pointer if the CMODE was not changed
5539 by client. Application must check for this.
5541 * Added <Server ID> argument to INFO command to support server
5542 info fetching by Server ID.
5544 * Added silc_server_announce_get_channel_users to get assembled
5545 packets of channel users of the specified channel. Affected
5546 file silcd/server.[ch].
5548 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
5549 was freed underneath the ID Cache.
5551 * Re-announce clients when the server received CHANNEL_CHANGE
5552 notify from the router. Affected file silcd/packet_send.c.
5554 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5556 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
5557 crashed since it did not handle the fact that there is no cipher
5558 called "3" and didn't check the error condition. Now fixed.
5560 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
5561 flag. It can be used to send message requests.
5563 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5565 * Implemented the RESTART command in the client.
5567 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
5568 notice type messages. Added notice printing to the user
5571 * The channel keys are not re-generated if the channel's mode
5572 is PRIVKEY, ie private key on the channel exists. Affected
5573 files silcd/server.c and silcd/command.c.
5575 * Fixed a little bug in channel message delivery when channel
5576 private keys are set in the server. Affected file is
5577 silcd/packet_send.c.
5579 * Changed the setting on channel->on_channel = TRUE from the
5580 silc_client_save_channel_key to the JOIN command reply. The
5581 key payload is not received if the private channel key is set.
5582 Affected file lib/silcclient/command_reply.c and the
5583 lib/silcclient/client_channel.c.
5585 * When the CMODE_CHANGE notify is sent and the channel private
5586 key mode is removed the channel key must be re-generated in
5587 other cells as well. Added this support for the router in the
5588 silcd/packet_receive.c.
5590 * Added new local command NOTICE to send notice message on
5591 channel. Affected file silc/local_command.[ch].
5593 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5595 * Added new local command ME to the client. It is used to send
5596 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
5597 some action. Affected file silc/local_command.[ch].
5599 * Changed channel_message and private_message client operations
5600 to deliver the message flags to the application. Added also
5601 the `flags' arguments to the silc_client_send_channel_message
5602 and silc_client_send_private_message functions. Affected file
5605 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5607 * Redefined the Private Message Payload to support private message
5608 keys and to support the new private message flags. Updated
5609 the protocol specs. Flags makes it possible to have for example
5610 CTCP style messages.
5612 * Added new type SilcPrivateMessagePayload and defined an API
5613 for it in the lib/silcclient/silcprivate.[ch].
5615 * Tested private message private keys successfully. Tested the
5616 private message key set, unset and list commands with the new
5619 * Redefined the Channel Message Payload to include the channel
5620 message flags (equal with private message flags) to support
5621 for example CTCP style messages.
5623 * Defined some of the message (for channel and private message)
5624 flags. Updated the protocol specs and added the flags to the
5625 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5627 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5629 * Added SilcKeyAgreementStatus type to the key agreement routines
5630 to indicate the current status and error if one occured.
5631 The status types are defined in the lib/silcclient/silcapi.h.
5633 * Added new local command KEY that is used to set and unset private
5634 keys for channels, set and unset private keys for private messages
5635 with remote clients and to send key agreement requests and
5636 negotiate the key agreement protocol with remote client. The
5637 key agreement is supported only to negotiate private message keys,
5638 it currently cannot be used to negotiate private keys for channels,
5639 as it is not convenient for that purpose.
5641 * Fixed a minor pending callback setting bug in the function
5642 silc_client_get_client_by_id_resolve, now the function works.
5643 Affected file lib/silcclient/idlist.c.
5645 * Added function silc_net_get_local_port to get local bound
5646 port by socket. Added to lib/silcutil/silcnet.[ch].
5648 * Added `sockets' and `sockets_count' fields to the SilcClient
5649 object. They hold the sockets of the listenning sockets in
5650 the client. Listenning sockets may be for example the key
5651 agreement server. Affected file lib/silcclient/client.[ch].
5652 Added functions the silc_client_add_socket and the
5653 silc_client_del_socket. They are exported to the application
5656 * Added ~./silc/clientkeys to support other client's public keys.
5658 * Renamed verify_server_key client operation to verify_public_key
5659 and added one argument to indicate the type of the connection
5660 (server, client etc.).
5662 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5664 * Added silc_server_connection_auth_request to handle the
5665 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5666 silcd/packet_receive.[ch].
5668 * Added silc_server_send_connection_auth_request into the
5669 silcd/packet_send.c to send the connection auth request packet.
5671 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5674 * Fixed the public key authentication in responder side in the
5675 server. The `auth_data' pointer includes the SilcPublicKey
5676 not the path to the public key. Affected file silcd/protocol.c.
5678 * Implemented the public key authentication in the initiator side
5679 in the server. Affected file silcd/protocol.c.
5681 * Removed the [RedirectClient] config section from the server
5682 configuration. Is not needed and I don't want to implement it.
5684 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5686 * Cleaned up the CMODE command in the server. It now works
5687 correctly and supports all the modes defined in the protocol.
5688 Affected file is silcd/command.c.
5690 * Added `hmac_name' field to the SilcChannelEntry in the server
5691 to hold the default HMAC of the channel. It can be set when
5692 creating the channel (with JOIN command). Affected files
5695 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5696 type to indicate the change of the current cipher and hmac
5697 on the channel. Client can safely ignore the <cipher> argument
5698 (if it chooses to do so) since the CHANNEL_KEY packet will
5699 force the channel key change anyway. The <hmac> argument is
5700 important since the client is responsible of setting the new
5701 HMAC and the hmac key into use.
5703 * Fixed the CMODE command in the client library as well.
5705 * Tested CMODE command in router environment successfully.
5707 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5709 * Show the version of the remote client (or server) when connecting
5710 to the server. It is logged to the log file. Affected file
5711 is silcd/protocol.c.
5713 * Fixed the KILLED notify handling in the client library. The
5714 client must be removed from all channels when receiving the
5717 Also, do not remove the client entry when giving the KILL
5718 command but when the KILLED notify is received.
5720 * Removed silc_idlist_find_client_by_nickname from the server.
5721 Not needed anymore. Affected files silcd/idlist.[ch].
5723 * Implemented the CHANNEL_CHANGE notify type handling to the
5724 server. Affected file silcd/server.c.
5728 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5730 * Added silc_server_send_notify_invite to send the INVITE
5731 notify between routers.
5733 * Implemented the INVITE command correctly to the server.
5735 * Implemented the INVITE notify type handling in the server.
5737 * Implemented the INVITE command to the client library and on the
5740 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5742 * Added function silc_server_get_client_resolve to find the
5743 client entry by ID from all ID lists and then resolve it
5744 (using WHOIS) if it cannot be found. Affected file is
5747 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5749 * Implemented the BAN command to the client library.
5751 * The JOIN command in the server now checks the invite list
5754 * Changed the silc_command_reply_payload_encode_va and the
5755 silc_command_payload_encode_va to support that if argument is
5756 NULL it ignores and checks the next argument. Affected file
5757 lib/silccore/silccommand.c.
5759 * Added silc_server_send_notify_ban to send the BAN notify
5760 type between routers.
5762 * Chaned the silc_notify_payload_encode to support that if
5763 argument is NULL it ignores and checks the next argument.
5764 Affected file lib/silccore/silcnotify.c.
5766 * Tested ban lists in router environment successfully.
5768 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5770 * Implemented BAN command to the server, in silcd/command.[ch].
5772 * Removed the BAN and INVITE_LIST modes from the CMODE command
5775 * Added function silc_string_match to regex match two strings.
5776 Affected files lib/silcutil/silcutil.[ch].
5778 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5780 * Redefined parts of the SilcChannelEntry in the server to support
5781 the new ban and invite lists.
5783 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5785 * Redefined the INVITE command. The same command can be used to
5786 invite individuals to the channel but also to manage the invite
5787 list of the channel (to add to and remove from the invite list).
5788 Updated the protocol specs.
5790 * Added new command SILC_COMMAND_BAN that can be used to manage
5791 the ban list of the channel. Updated the protocol specs.
5793 * Removed the channel modes: the SILC_CMODE_BAN and the
5794 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5795 in the CMODE command. The equivalent features are now available
5796 using INVITE and BAN commands. Updated the protocol specs.
5798 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5799 in the network about change in the current ban list. The notify
5800 type is not used by the client.
5802 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5803 support the invite lists.
5805 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5807 * Added new function silc_string_regexify that converts string
5808 including wildcard characters into regex string that can
5809 be used by the GNU regex library. Added into the file
5810 lib/silcutil/silcutil.[ch].
5812 Added silc_string_regex_combine to combine to regex strings
5813 into one so that they can be used as one regex string by
5814 the GNU regex library. Added into the file
5815 lib/silcutil/silcutil.[ch].
5817 Added silc_string_regex_match to match two strings. It returns
5818 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5820 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5822 * Imported GNU regex to the soruce tree into lib/contrib.
5823 Fixed some compiler warning from the regex.c.
5825 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5827 * Fixed MOTD command in the server to work in router environment.
5829 * Fixed the MOTD command in the client library to support
5830 the server argument in the command.
5832 * Added `nickname_len' argument to the silc_idlist_add_client
5833 in the server, as the `nickname' argument may be binary data
5836 * Added silc_idlist_get_channels to return all channels from
5839 * Implemented LIST command to the server. Affected file is
5842 * Implemented the LIST command to the client library and on the
5845 * Added [<user count>] argument to the LIST command reply.
5846 With private channels the user count is not shown.
5848 * Updated TODO and README.
5850 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5852 * The client entry's data.registered must be TRUE even with
5853 global client entry on global client list. The data.registered
5854 is used to check whether the client is anymore in the network,
5855 for example with WHOWAS command so it must be valid.
5857 * Fixed the WHOWAS command in the server. It now actually works
5858 in router environment. Added function into silcd/command_reply.c
5859 silc_server_command_reply_whowas_save.
5861 * Added silc_idlist_purge function to the silcd/idlist.c
5862 to periodically purge the ID Cache.
5864 * Fixed INFO command in the server. It works now in router
5865 environment. Added <server name> argument to the INFO command
5866 reply. Updated the protocol specs.
5868 * Fixed minor bug in silc_idcache_purge to not purge if the
5869 expire value is zero.
5871 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5872 they were buggy because of the WHOWAS information.
5874 * Fixed local command MSG to handle the async resolving of
5875 the remote client properly. It used to fail the first MSG.
5876 Affected file silc/local_command.c.
5878 * Added `data_len' field to SilcIDCache context.
5880 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5882 * Update TODO. Todo in commands in the server.
5884 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5886 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5887 used by routers as broadcast packet to inform other routers
5888 about the changed user mode.
5890 Implemented the notify handling in the server. Affected file is
5891 silcd/packet_receive.c. Added the function
5892 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5894 * Added new generic Channel Payload and deprecated the New Channel
5895 Payload. The New Channel Payload is now the generic Channel
5898 * Added new argument `mode' to the silc_server_send_new_channel
5899 as it is required in the Channel Payload now.
5901 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5902 and created a new and real SilChannelPayload to represent the
5903 new generic Channel Payload. Implemented the encode/decode
5904 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5906 * Added silc_server_get_client_channel_list to return the list
5907 of channels the client has joined for WHOIS command reply.
5908 Affected file silcd/server.[ch].
5910 * Implemented the channel list sending in the WHOIS command reply
5911 in server and in the client.
5913 Implemented the channel list displaying on the user interface
5914 as well. Affected file silc/client_ops.c.
5916 * Added silc_channel_payload_parse_list to parse list of Channel
5917 Payloads. It returns SilcDList list of SilcChannelPayloads.
5918 Client for example can use this function to parse the list of
5919 channels it receives in the WHOIS command reply. The caller
5920 must free the list by calling silc_channel_payload_list_free.
5921 Affected files lib/silccore/silcchannel.[ch].
5923 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5925 * Added one new argument <user mode> to the WHOIS command reply
5926 to return the mode of the user in SILC. Updated the protocol
5929 Implemented it to the server and client.
5931 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5933 * Fixed the mode printing on the user interface on joining.
5934 Affected file silc/client_ops.c.
5936 * Implemented the UMODE command and user modes in general to the
5937 client library and to the user interface.
5939 * Implemented the UMODE command to the server.
5941 * The server now sends UNKNOWN_COMMAND error status if client sends
5942 unknown command. Affected file silcd/command.c.
5944 * All server commands now handle the command identifier the right
5945 way when sending the command reply to the client. The client can
5946 use to identify the command replies with the identifier.
5948 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5950 * Added silc_server_get_client_route to resolve the route to
5951 the client indicated by the client ID. Affected file is
5954 * Added silc_server_relay_packet as general function to relay
5955 packet to arbitrary destination. This deprecates functions
5956 like _send_private_message_key, _relay_notify etc. Affected
5957 file is silcd/packet_send.[ch].
5959 Removed silc_server_send_key_agreement,
5960 silc_server_send_private_message_key and
5961 silc_server_packet_relay_notify functions from the file
5962 silcd/packet_send.[ch].
5966 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5967 server. Affected file silcd/packet_receive.[ch].
5969 * Implemented the KILL command to the client. Implemented the
5970 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5971 Affected files lib/silcclient/command[_reply].c and
5972 lib/silcclient/client_notify.c. Implemented the KILL notify
5973 printing in the user inteface.
5975 * Fixed a lot silc_parse_nick memory leaks from the client
5976 library in the file lib/silcclient/command.c.
5978 * Changed the silc_server_send_notify_on_channels's `sender'
5979 argument from SilcSocketConnection to SilcClientEntry to
5980 check the sender as entry and not as connection object and not
5981 to send to the client provided as argument. The affected file
5982 is silcd/packet_send.[ch].
5984 * The notify packets that are destined directly to the client used
5985 to not to be processed by the server. Now changed that and the
5986 server processes all notify packets. After relaying the packet
5987 to the client the notify packet is processed in the server.
5989 * The silc_server_free_client_data now checks whether there is
5990 pending outgoing traffic for the client and purges the data to
5991 the network before removing the client entry.
5993 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5995 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5996 an client is killed from the SILC Network. Updated the protocol
5999 Added new function silc_server_send_notify_killed to the
6000 silcd/packet_send.[ch].
6002 * Added function silc_server_packet_relay_notify to relay notify
6003 packets that are destined directly to a client. In this case
6004 the server does not process the notify packets but merely relays
6005 it to the client. Affected file silcd/packet_send.[ch].
6007 Added also silc_server_packet_process_relay_notify to check
6008 whereto relay the notify. Affected file is
6009 silcd/packet_receive.[ch].
6011 * Implemented the KILL command to the server.
6015 * Added the backup schema desgined last fall to the protocol
6016 specs for everyone to see. The specification is in the
6017 *-spec-xx.txt draft and the packet type definitions for the
6018 backup routers is in *-pp-xx.txt draft. Thusly, added also
6019 new packet type SILC_PACKET_CELL_ROUTERS.
6021 * A big security problem in the implementation discovered. The
6022 signoff of an client did not cause new channel key generation
6023 which it of course should've done. The channel keys must be
6024 always re-generated when client leaves (or signoffs) the channel.
6025 The silc_server_remove_from_channels funtion now handles
6026 the channel key re-generation.
6028 * Added `sender' argument to the silc_server_send_notify_on_channels
6029 to not to send the client provided as argument. Affected file
6030 silcd/packet_send.[ch].
6032 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6034 * Implemented OPER and SILCOPER commands into the server and
6037 * Added silc_auth_verify and silc_auth_verify_data to verify
6038 the authentication directly from the authentication payload.
6039 It supports verifying both passphrase and public key based
6040 authentication. Affected file lib/silccore/silcauth.[ch].
6042 * Added `hash' field to the SilcIDListData structure. It is the
6043 hash negotiated in the SKE protocol. Affected file is
6046 * Slight redesigning of the SilcAuthPayload handling routines.
6047 Do not send SilcPKCS but SilcPublicKey as argument.
6049 * Implemented the public key authentication support to the
6050 serverconfig. The public key is loaded from the provided path
6051 and saved as authentication data to void * pointer. Thus,
6052 changed the unsigned char *auth_data to void *auth_data;
6054 * Fixed SHUTDOWN command to send the reply before the server
6055 is shutdown. :) Affected file silcd/command.c.
6057 * Fixed fatal bug in CONNECT command. The hostname was invalid
6058 memory and server crashed. Affected file silcd/command.c.
6060 * Fixed fatal bug in CLOSE command. The server_entry became
6061 invalid but was referenced later in the command. Affected file
6064 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6066 * Fixed fatal bug in failure packet handling. Server ignored
6067 the failure and thus crashed when it came.
6071 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6073 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
6074 that the command may be executed only once in (about) 2 seconds.
6075 The old SILC_CF_LAG flag is same but allows command bursts up
6076 to five before limiting.
6078 Added the support for CF_LAG and CF_LAG_STRICT flags to the
6079 server code. Various commands now includes the CF_LAG_STRICT
6080 flag to disallow any kind of miss-use of the command.
6082 * Fixed the silc_buffer_unformat to not to allocate any data
6083 if the length of the data is zero. It used to allocate the
6084 length + 1. Affected file lib/silcutil/silcbuffmt.c.
6086 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6088 * Changed the format of AdminConnection configuration section
6089 in the server. Added username of the admin to the format.
6090 Affected files silcd/serverconfig.[ch].
6092 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
6093 to return admin configuration data by host, username and/or
6096 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6098 * Implemented WHOWAS command to the server. Added the functions:
6100 silc_server_command_whowas_parse,
6101 silc_server_command_whowas_send_reply,
6102 silc_server_command_whowas_from_client and
6103 silc_server_command_whowas_from_server
6105 * Added <Client ID> argument to the WHOWAS command reply. Updated
6106 the protocol specs accordingly.
6108 * Implemented WHOWAS command and command_reply to the client
6111 Implemented the WHOWAS printing on the user interface.
6113 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6115 * Added new argument to the WHOWAS command reply, the real name.
6116 It is an optional argument. Updated the protocol specs.
6118 * Added SilcIDCacheDestructor callback that is registered when
6119 the SilcIDCache is allocated. The callback is called when
6120 an cache entry in the ID Cache expires, or is purged from the
6121 cache. Added into lib/silccore/idcache.[ch].
6123 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
6124 to destruct the client entries when the cache entry expires.
6125 Other ID Cache's in server and in the client library ignores
6128 * If the ID Cache entry's `expire' field is zero then the entry
6129 never expires. Added boolean `expire' argument to the
6130 silc_idcache_add function in the lib/silccore/idcache.[ch].
6131 If it is TRUE the default expiry value is used.
6133 * Added silc_server_free_client_data_timeout that is registered
6134 when client disconnects. By default for 5 minutes we preserve
6135 the client entry for history - for WHOWAS command.
6137 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6139 * Added support to the server to enforce that commands are not
6140 executed more than once in 2 seconds. If server receives
6141 commands from client more frequently, timeout is registered
6142 to process the commands. Affected file silcd/command.c.
6143 Added new function silc_server_command_process_timeout.
6145 * Changed NICK_NOTIFY handling in client library to check that
6146 if the client's nickname was changed, so there is no need to
6147 resolve anything from the server.
6149 * Removed error printing from the WHOIS and IDENTIFY commands.
6150 If error occurs then it is ignored silently in the client library.
6151 The application, however, may map the received error to
6152 human readable error string. The application currently maps
6153 the NO_SUCH_NICKNAME error to string.
6155 * Made the command status message public to the application. Moved
6156 them from lib/silcclient/command_reply.c to
6157 lib/silcclient/command_reply.h. The application can map the
6158 received command status to the string with the
6159 silc_client_command_status_message function.
6161 * Added check to the server to check that client's ID is same
6162 as the Source ID in the packet the client sent. They must
6165 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6167 * Added dist-bzip hook to the Makefile.am to make bzip2
6168 compressed distributions.
6170 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6172 * Server now enforces the maximum length for the nickname and
6173 the channel as protocol specification dictates. 128 bytes for
6174 nickname and 256 bytes for channel name.
6176 * Moved the WHOIS printing to the application. The client libary
6177 does not print out the WHOIS information anymore, the application
6178 must do it. Renamed silc_client_command_reply_whois_print to
6179 the silc_client_command_reply_whois_save.
6181 The client's idle time is also sent to the application now, and
6182 the idle is shown on screen.
6184 * Added silc_client_command_reply_identify_save to save the
6185 received IDENTIFY entries.
6187 * Do not check for channel private keys in message sending and
6188 reception if the channel does not have the PRIVKEY mode set.
6189 Affected file lib/silclient/client_channel.c.
6191 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6193 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
6194 just surfaced after chaning the JOIN procedure.
6196 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6198 * Added silc_client_get_clients_by_list to get client entries
6199 from Client ID list, that is returned for example by JOIN
6200 and USERS command replies. The application should use this
6201 function for example when JOIN command reply is received to
6202 resolve the clients already on the channel (library does not
6203 do that anymore as USERS command reply is not used in the JOIN
6204 procedure anymore). Affected files lib/silcclient/silcapi.h and
6205 lib/silcclient/idlist.c.
6207 * JOIN command reply and USERS command reply returns now SilcBuffer
6208 pointers instead of unsigned char pointers when returning
6209 the client list and mode list.
6211 * Added <Client ID> argument to the JOIN command reply, mainly
6212 for the server to identify for which client the command was
6213 originally sent. Updated protocol specs accordingly.
6215 * Added SilcDlist private_key pointer to the SilcChannelEntry
6216 in the client to support the channel private keys. Affected
6217 file is lib/silcclient/idlist.h.
6219 * Added SilcChannelPrivateKey argument to the function
6220 silc_client_send_channel_message so that application can choose
6221 to use specific private ke if it wants to. If it is not provided,
6222 the normal channel key is used, unless private keys are set.
6223 In this case the first (key that was added first) is used
6224 as the encryption key.
6226 * Implemented the support for channel private key handling.
6227 Implemented the following functions:
6229 silc_client_add_channel_private_key,
6230 silc_client_del_channel_private_keys,
6231 silc_client_del_channel_private_key,
6232 silc_client_list_channel_private_keys and
6233 silc_client_free_channel_private_keys
6235 Affected file lib/silcclient/client_channel.c.
6237 * Added the support for the private keys in the channel message
6238 sending and encryption and in the message reception and
6239 decryption. Affected funtions are
6240 silc_client_send_channel_message and silc_client_channel_message.
6242 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6244 * Added SKE's key verify callback to the client library's
6245 KE protocol context. Affected files lib/silcclient/protocol.[ch].
6247 * Removed the statement that server (or router) must send USERS
6248 command reply when joining to the channel so that the client
6249 knows who are on the channel. Instead, the client list and
6250 client's mode list is now sent in the JOIN command reply to the
6251 client who joined channel. This is better solution.
6253 * Added function silc_server_get_users_on_channel and function
6254 silc_server_save_users_on_channel to the silcd/server.[ch].
6256 * Removed function silc_server_command_send_users from the
6259 * Do not show topic on the client library anymore. The topic is
6260 sent in the command reply notify to the application and the
6261 application must show the topic now.
6263 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6265 * Added client searching by nickname hash into the IDENTIFY and
6266 WHOIS commands in the server as they were clearly missing from
6267 them. Affected file is silcd/command.c.
6269 * Fixed a bug in private message receiving in the client library.
6270 The remote ID was freed and it wasn't supposed, now it is
6273 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6275 * Minor fix to the channel payload; allocate the data area, as it
6276 needs to be of specific length.
6278 * If the key agreement port is zero then the operating
6279 system will define the bound port. Affected files are
6280 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
6282 * Added new function silc_channel_payload_decrypt into the file
6283 lib/silccore/silcchannel.[ch].
6285 * Moved the channel message etc, check from silc_packet_decrypt
6286 to applications. The library calls now a generic
6287 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
6288 when the packet is either normal or special. This was done to
6289 allow more wide range of checking that was not allowed when
6290 the code was in library. Now applications can do virtually any
6291 checks to the packet and return to the library the decision how
6292 the packet should be processed. Affected files are
6293 lib/silccore/silcpacket.[ch].
6295 Added silc_server_packet_decrypt_check to the server and
6296 silc_client_packet_decrypt_check to the client library.
6298 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
6299 to send with specified source and destination information.
6301 * Channel message delivery between routers was broken after the
6302 channel key distribution was fixed earlier. The channel key
6303 was used be to distributed to other routers as well which is not
6304 allowed by the protocol. Now this is fixed and channel keys
6305 really are cell specific and the channel message delivery between
6306 routers comply with the protocol specification.
6308 * Fixed various commands in server to check also the global list
6309 for the channel entry and not just the local list. The affected
6310 file silcd/command.c.
6312 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6314 * Added assert()s to buffer formatting and unformatting routines
6315 to assert (if --enable-debug) when error occurs. Affected
6316 file: lib/silcutil/silcbuffmt.c.
6318 * Changed to auto-reconnect to check whether the remote host is
6319 router and register the re-connect timeout if it is. It used
6320 to check that whether we are normal server, but router must do
6321 auto-reconnect with another router as well. Affected file
6324 * Removed the [<key len>] option from CMODE command as the cipher
6325 name decides the key length, nowadays. See the defined ciphers
6326 from the protocol specification.
6328 * Added [<hmac>] option to the CMODE command to define the HMAC
6329 for the channel. Added SILC_CMODE_HMAC channel mode.
6331 * Added [<hmac>] option for the JOIN command so that user can
6332 select which HMAC is used to compute the MACs of the channel
6335 * Added Hmac field to the Channel Message Payload. The integrity
6336 of plaintext channel messages are now protected by computing
6337 MAC of the message and attaching the MAC to the payload. The
6338 MAC is encrypted. Now, it is clear that this causes some
6339 overhead to the size of the packet but rationale for this is that
6340 now the receiver can verify whether the channel message decrypted
6341 correctly and also when private keys are set for the channel the
6342 receiver can decrypt the packet with several keys and check from
6343 the MAC which key decrypted the message correctly.
6345 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
6346 lib/silccrypt/silccipher.[ch].
6348 * Added silc_hash_len to return the digest length into the
6349 lib/silcrypt/silchash.[ch].
6351 * Rewrote parts of Silc Channel Payload interface in the
6352 lib/silccore/silcchannel.[ch]. The encode function now also
6353 encrypts the packet and parse function decrypts it.
6355 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6357 * Fixed a minor formatting bug in the SKE's key material processing.
6358 It actually might have processed the keys wrong way resulting
6361 * Redefined the mandatory HMAC algorithms and added new algorithms.
6362 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
6363 and hmac-md5 truncated to 96 bits. The mandatory is now
6364 hmac-sha1-96. Rest are optional (including the one that used
6365 to be mandatory). Rationale for this is that the truncated HMAC
6366 length is sufficient from security point of view and can actually
6367 make the attack against the HMAC harder. Also, the truncated
6368 HMAC causes less overhead to the packets. See the RFC2104 for
6371 * Added new [hmac] configuration section. The SKE used to use
6372 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
6373 is of course wrong. The official names that must be proposed in
6374 the SKE are the ones defined in the protocol specification
6375 (hmac-sha1-96 for example). The user can configure any hmac
6376 using any hash function configured in the [hash] section. At
6377 least, the mandatory must be configured.
6379 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
6381 * Added HMAC list to the SKE proposal list. It has now both
6382 hash algorithm list and HMAC list. This makes the protocol
6383 incompatible with previous versions. The SKE now seems to work
6384 the way it is supposed to work, for the first time actually.
6386 * Defined plain Hash algorithms to the protocol specification.
6389 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6391 * Implemented support for key agreement packets into the server.
6392 Added functions silc_server_key_agreement and
6393 silc_server_send_key_agreement. Other than these functions,
6394 server has nothing to do with this packet.
6396 * Added support for private message key packets into the server.
6397 Added functions silc_server_private_message_key and
6398 silc_server_send_private_message_key.
6402 * Changed the silc_[client|server]_protocol_ke_set_keys to be
6403 called in the protocol's final callback instead in the END
6404 protocol state. This makes a little more sense and in the same
6405 time in client we can use the same protocol routines for normal
6406 key exchange and to key agreement packet handling as well.
6408 * Added to both client's and server's KE protocol context the
6409 SilcSKEKeyMaterial pointer to save the key material. We will
6410 bring the key material to the protocol's final callback by doing
6411 this. The final callback must free the key material.
6413 * Added SKE's packet_send callback into client's KE protocol
6414 context so that the caller can choose what packet sending function
6415 is used. This way we can use different packet sending when
6416 doing normal SKE when doing key agreement packet handling (in
6417 the key agreement packet handling we do not want to encrypt
6420 * Implemented the responder side of the key agreement routines
6421 in the client. The client can now bind to specified port and
6422 accept incoming key negotiation. The key material is passed
6423 to the application after the protocol is over.
6425 * Implemented the processing of incoming Key Agreement packet
6426 in the client. Added function silc_client_key_agreement to
6429 * Implemented the intiator side of the key agreement routines
6430 in the client. The client can now initiate key agreement with
6431 another remote client. The key material is passed to the
6432 application after the protocol is over.
6434 * Created client_keyagr.c to include all the key agreement
6437 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
6438 SILC_TASK_CALLBACK except that it is not static.
6440 * Created client_notify.c and moved the Notify packet handling
6441 from the client.[ch] into that file.
6443 * Created client_prvmsg.c and moved all private message and
6444 private message key routines from the client.[ch] into that file.
6446 * Create client_channel.c and moved all channel message and
6447 channel private key routines from the client.[ch] into that file.
6449 * Changed silc_client_get_client_by_id_resolve to resolve with
6450 WHOIS command instead of IDENTIFY command, in the file
6451 lib/silclient/idlist.c.
6453 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6455 * Implemented the SKE's responder side to the Client library.
6457 * When FAILURE is received to the protocol do not trust it
6458 blindly. Register a timeout to wait whether the remote closes
6459 the connection as it should do it, only after that process the
6460 actual failure. This was changed to both client and server.
6462 * Added client_internal.h to include some of the structures
6463 there instead of client.h in lib/silcclient/.
6465 * Added function silc_task_unregister_by_callback to unregister
6466 timeouts by the callback function.
6468 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6470 * Some "Incomplete WHOIS info" errors has been appearing on the
6471 log files. Took away the entry->userinfo check from WHOIS
6472 reply sending. The entry->userinfo is now " " if client did not
6473 provide one. I thought this was fixed earlier but something
6474 is wrong still. Let's see if the error still appears.
6476 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6478 * Fixed a minor bug in the login when the channel key is
6479 re-generated in the server. It used to generate the key in
6480 wrong order and thus caused problems in the channel traffic.
6482 * Fixed a minor bug in channel key distsribution after
6483 KICK command. The key was not sent to the router even though
6486 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6488 * Added silc_ske_process_key_material_data as generic routine
6489 to process any key material as the SILC protocol dictates. The
6490 function is used by the actual SKE library but can be used by
6491 applications as well. This relates to the private message keys
6492 and the channel private keys since they must be processed the
6493 same way the normal SILC session keys. The protocol dictates
6494 this. Affected files: lib/silcske/silcske.[ch].
6496 Added also silc_ske_free_key_material to free the
6497 SilcSKEKeyMaterial structure.
6499 * Defined silc_cipher_set_key function to set the key for
6500 cipher without using the object's method function. The affected
6501 files: lib/silccrypt/silccipher.[ch].
6503 * Implemented silc silc_client_add_private_message_key,
6504 silc_client_add_private_message_key_ske,
6505 silc_client_del_private_message_key,
6506 silc_client_list_private_message_keys and
6507 silc_client_free_private_message_keys functions in the
6510 Added functions silc_client_send_private_message_key to send
6511 the Private Message Key payload and silc_client_private_message_key
6512 to handle incoming Private Message Key payload.
6514 * Added Cipher field to the Private Message Key payload to set
6515 the cipher to be used. If ignored, the default cipher defined
6516 in the SILC protocol (aes-256-cbc) is used.
6518 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6520 * Removed lib/silcclient/ops.h file.
6522 Redefined parts of the SILC Client Library API. Created new
6523 file silcapi.h that deprecates the ops.h file and defines the
6524 published Client Library API. Defined also private message key
6525 API and channel private key API into the file.
6527 This is the file that the application must include from the
6528 SILC Client Library. Other files need not be included by
6529 the application anymore.
6531 * Added new key_agreement client operation callback and also
6532 defined the Key Agreement library API for the application.
6534 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6536 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
6537 is used by clients to request key negotiation between another
6538 client in the SILC network. If the negotiation is started it
6539 is performed using the SKE protocol. The result of the
6540 negotiation, the secret key material, can be used for example
6541 as private message key.
6543 Implemented the Key Agreement payload into the files
6544 lib/silccore/silauth.[ch].
6546 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6548 * Redefined ciphers for the SILC protocol. Added some new ciphers
6549 and defined the key lengths for the algorithms. Changed the
6550 code accordingly. The default key length is now 256 bits.
6552 * Fixed SKE key distribution function silc_ske_process_key_material
6553 when the key length is more than 128 bits. The default key
6554 length in SILC is now 256 bits.
6556 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
6557 to indicate unsupported algorithm.
6559 * Renamed rijndael.c to aes.c and all functions as well.
6561 * Fixed a long standing channel key setting bug in client library.
6562 Weird that it has never surfaced before.
6564 * Fixed bug in channel deletion. If the entire channel is removed
6565 then it must also delete the references of the channel entry
6566 from the client's channel list as the client's channel entry and
6567 the channel's client entry share same memory.
6569 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6571 * Implemented CONNECT and SHUTDOWN commands in the client.
6573 * Implemented CLOSE command to the client.
6575 * Added the function silc_idlist_find_server_by_name into the
6576 files silcd/idlist.[ch].
6578 Added the function silc_idlist_find_server_by_conn into the
6579 files silcd/idlist.[ch].
6581 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6583 * DIE command was renamed to SHUTDOWN. Updated the both code
6586 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
6587 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
6589 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
6592 * Added function silc_server_create_connection function to create
6593 connection to remote router. My server implementation actually
6594 does not allow router to connect to normal server (it expects
6595 that normal server always initiates the connection to the router)
6596 so the CONNECT command is only good for connecting to another
6599 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6601 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
6602 or some other client was kicked from the channel.
6604 Implemented the handling of the notify type to both client
6607 Implemented silc_server_send_notify_kicked to send the KICKED
6608 notify. It is used to send it to the server's primary router.
6610 * Implemented the KICK command into server and client.
6612 * Added `query' argument to the silc_idlist_get_client function
6613 to indicate whether to query the client from server or not if
6616 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
6617 to indicate that the client is not channel founder.
6621 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6623 * Removed the rng context from SilcPacketContext structure and
6624 changed that the packet routine uses the Global RNG API.
6626 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6628 * Added support for quit message that client can "leave" on the
6629 channel when it quits the SILC. It is ditributed inside the
6630 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6632 Added silc_server_free_client_data that will take the
6633 signoff message as argument.
6635 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6637 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6639 * Updated parts of the protocol specification to keep it up
6642 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6644 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6645 payloads in one packet.
6647 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6648 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6649 use now the new List flag.
6651 * Also deprecated the following packet types: REPLACE_ID,
6652 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6654 * Added list support for Notify packet in server.
6656 * Added silc_server_send_notify_channel_change to send the
6657 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6658 the silc_server_send_replace_id.
6660 * Added silc_server_send_notify_nick_change to send the
6661 NICK_CHANGE notify type. Deprecates the function
6662 silc_server_send_replace_id.
6664 * Added silc_server_send_notify_join to send the JOIN notify type.
6665 Deprecates the function silc_server_send_new_channel_user.
6667 * Added silc_server_send_notify_leave to send LEAVE notify type.
6668 Deprecates the function silc_server_send_remove_channel_user.
6670 * Added silc_server_send_notify_cmode and
6671 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6672 types. Deprecates the silc_server_send_set_mode function.
6674 * Added SERVER_SIGNOFF notify type to indicate that server has
6675 quit. This means that all clients on the channel from that
6676 server will drop. This can be also used when netsplit happens.
6678 Deprecated REMOVE_ID packet type since it is not needed anymore
6681 Added silc_server_send_notify_server_signoff to send the
6682 SERVER_SIGNOFF notify type. Deprecates the function
6683 silc_server_send_remove_id.
6685 Added also silc_server_send_notify_signoff to send the
6686 SIGNOFF notify type.
6688 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6689 SILC protocol from this day on. Changed the protocol
6690 specification as well.
6692 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6693 notify type. It is used between routers to notify about
6694 topic changes on a channel.
6696 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6699 * Partly updated the protocol specification to comply with the
6700 changes now made. It is still though a bit outdated.
6702 * The JOIN notify type now takes one extra argument <Channel ID>.
6703 The packet used to be destined to the channel but now the
6704 JOIN type may be sent as list thus it is impossible to
6705 destine it to any specific channel. By adding this argument
6706 it is again possible.
6708 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6710 * Added CREDITS file. The CHANGES and CREDITS file will appear
6711 in the distribution as well.
6713 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6715 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6716 types in the server's silcd/packet_receive.c.
6718 * Implemented CMODE and CUMODE to work in router environment.
6720 * Fixed minor encoding and decoding buglet from the
6721 lib/silccore/silcmode.c.
6723 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6726 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6728 * Changed all SilcConfigServer* and silc_config_server* to
6729 SilcServerConfig* and silc_server_config*, respectively.
6732 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6734 * Associated the ID (client or server ID) to the Authentication
6735 Payload to avoid any possibility of forging. Updated the
6736 protocol specification and the code accordingly.
6738 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6740 * The RSA key length is now save to the RsaKey context in the
6741 key generation process in lib/silccrypt/rsa.c. The key length
6742 is now used to figure out the maximum size of the block allowed
6743 to be encrypted/signed.
6745 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6746 is equivalent to the silc_mp_mp2bin but does not allocate any
6749 * Changed silc_mp_mp2bin API to take length argument. If it is
6750 non-zero then the buffer is allocated that large. If zero, then
6751 the size is approximated using silc_mp_sizeinbase, which however
6754 * Created Global RNG API which is global RNG that application can
6755 initialize. After initializing, any routine anywhere in the
6756 code (including library) can use RNG without allocating a new
6757 RNG object. This was done to allow this sort of use of the
6758 RNG in code that has no chance to allocate RNG object. All
6759 applications currently allocate this and many routines in the
6760 library use this. Affected file lib/silccrypt/silcrng.[ch].
6762 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6763 it to use the Global RNG API.
6765 * Defined Authentication Payload into protocol specification that
6766 is used during SILC session to authenticate entities. It is
6767 used for example by client to authenticate itself to the server
6768 to obtain server operator privileges.
6770 Implemented this payload into the lib/silccore/silcauth.[ch].
6771 Implemented also routines for public key based authentication
6772 as the new protocol specification dictates.
6774 Moved definitions of different authentication methods from
6775 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6777 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6778 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6779 silc_pkcs_verify_with_hash functions into the file
6780 lib/silccrypt/silcpkcs.[ch].
6782 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6784 * The client entry's userinfo pointer must be always valid.
6785 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6786 will fail since it requires the userinfo. Now, the userinfo
6787 is allocated as "" if actual userinfo does not exist. Actually,
6788 it must exist and it is totally Ok to drop client connections
6789 that does not announce the userinfo. However, we will make
6790 this workaround for now.
6792 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6793 to return the remote port by socket.
6795 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6797 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6798 SILC_SERVER_PENDING_EXEC and added an new macro
6799 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6800 data or when error occurs while processing the pending command.
6802 Added new argument `destructor' into silc_server_command_pending
6803 and to the SilcServerCommandPending object. This destructor is
6804 now called after calling the pending callback or if error occurs
6805 immediately. If error occurs the actual pending callback won't
6806 be called at all - only the destructor. The destructor may be
6807 NULL if destructor is not needed.
6809 All this applies for client library code as well. Similar
6810 changes were made there as well for the pending commands.
6812 In the client, the application must now allocate the
6813 SilcClientCommandContext with the silc_client_command_alloc
6816 * Added reference counter to the SilcServerCommandContext. Added
6817 function silc_server_command_alloc and silc_server_command_dup
6820 Same type of functions added to the client library for the same
6823 * Removed the cmd_ident from IDListData away since it is now
6824 global for all connections. It is the command identifier used
6825 in command sending and with pending commands. The affected file
6828 * Added reference counter to the SilcSocketConnection objecet to
6829 indicate the usage count of the object. The object won't be
6830 freed untill the reference counter hits zero. Currently only
6831 server uses this, and client ignores it. The client must be
6832 set to use this too later. The affected files are
6833 lib/silccore/silcsockconn.[ch]. Added also the function
6834 silc_socket_dup to increase the reference counter.
6836 This was mainly added because it is possible that the socket
6837 is removed underneath of pending command or other async
6838 operation. Now it won't be free'd and proper DISCONNECTING
6839 flags, etc. can be set to avoid sending data to connection that
6840 is not valid anymore.
6842 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6843 the connection. After that it sets SILC_SET_DISCONNECTED.
6844 It is, however, possible that the socket data is not still freed.
6845 The silc_server_packet_process now checks that data is not
6846 read or written to connection that is DISCONNECTED. The socket
6847 get's freed when the reference counter hits zero.
6849 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6851 * Changed the client operation API: channel_message operation's
6852 `sender' is now the client entry of the sender, not the nickname
6853 and the `channel' is the channel entry, not the channel name.
6855 In the private_message operation the `sender' is now also the
6856 client entry of the sender not the nickname.
6858 Affected file is lib/silcclient/ops.h and all applications
6859 using the client operations.
6861 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6863 * Moved the calling of ops->connect() from connect_to_server_final
6864 into receive_new_id functin since that is the point when the
6865 client is actually allowed to send traffic to network. The
6866 affected file is lib/silcclient/client.c.
6868 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6870 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6871 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6872 (if needs broadcasting) instead of broadcasting the packets one
6873 by one which would make a burst in the network traffic.
6875 * Added `broadcast' argument to the functions in silcd/server.[ch]
6876 silc_server_create_new_channel[_with_id] to indicate whether
6877 to send New Channel packet to primary router.
6879 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6881 * Added new function into the silcd/server.[ch] files:
6882 silc_server_create_new_channel_with_id to create new channel with
6883 already existing Channel ID.
6885 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6886 lib/silccore/silcpacket.h. This packet is used t send list of
6887 Set Mode payloads inside one packet. Server uses this to set
6888 the modes for the channels and clients on those channels, that it
6889 announced to the router when it connected to it. The protocol
6890 specification has been updated accordingly.
6892 * The silc_server_new_channel did not handle the packet coming
6893 from normal server as it normally does not send that. However,
6894 when it announces its channels it does send it. Implemented
6895 the support for that.
6897 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6898 into the file lib/silccore/id.h.
6900 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6902 * Fixed memory leaks in the functions silc_idlist_del_client,
6903 silc_idlist_del_channel and silc_idlist_del_server in the file
6904 silcd/idlist.c. All of those leaked like a sieve.
6906 * Fixed some small memory leaks in the client's function
6907 silc_client_notify_by_server.
6909 * Added functions into silcd/server.c: silc_server_announce_clients,
6910 silc_server_announce_channels and silc_server_announce_server.
6911 These functions are used by normal and router server to announce
6912 to its primary router about clients, channels and servers (when
6913 router) that we own. This is done after we've connected to the
6916 These functions effectively implements the following packet types:
6917 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6918 and SILC_PACKET_NEW_ID_LIST.
6920 * Added new functions into the silcd/packet_receive.[ch]:
6921 silc_server_new_id_list, silc_server_new_channel_list and
6922 silc_server_new_channel_user_list to handle the incoming
6923 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6925 * Added support of changing Channel ID in the function
6926 silc_server_replace_id. If the server that announces a channel
6927 to the router already exists in the router (with same name but
6928 with different Channel ID), router is responsible to send
6929 Replace ID packet to the server and force the server to change
6930 the Channel ID to the one router has.
6932 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6933 client that the Channel ID has been changed by the router. The
6934 normal server sends this to the client. Client must start using
6935 the new Channel ID as the channel's ID.
6937 Implemented handling of this new type into lib/silcclient/client.c
6938 into the function silc_client_notify_by_server.
6940 * Added new function silc_idlist_replace_channel_id into the files
6941 silcd/idlist.[ch] to replace the Channel ID.
6943 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6945 * Call silc_server_command_identify_check always when processing
6946 the IDENTIFY command in silcd/command.c
6948 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6950 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6951 send keepalive packets. The packet can be sent by clients,
6952 servers and routers.
6954 Added function silc_socket_set_heartbeat into the file
6955 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6956 If not set, the heartbeat is not performed. The actual
6957 heartbeat is implemented in the low level socket connection
6958 library. However, application is responsible of actually
6961 Added silc_server_send_heartbeat to send the actual heartbeat
6962 packet into silcd/packet_send.[ch]. Server now performs
6963 keepalive with all connections.
6965 * Added silc_task_get_first function into lib/silcutil/silctask.c
6966 to return the timeout task with shortest timeout. There was a bug
6967 in task unregistration that caused problems. TODO has been
6968 updated to include that task system must be rewritten.
6970 * The client library will now resolve the client information when
6971 receiving JOIN notify from server for client that we know but
6972 have incomplete information.
6974 * Rewrote parts of silc_server_remove_from_channels and
6975 silc_server_remove_from_one_channel as they did not remove the
6976 channel in some circumstances even though they should've.
6978 * Encryption problem encountered in server:
6980 The LEAVE command used to send the Channel Key packet to the
6981 router immediately after generating it. However, the code
6982 had earlier sent Remove Channel user packet but not immediately,
6983 ie. it was put to queue. The order of packets in the router
6984 was that Channel Key packet was first and Remove Channel User
6985 packet was second, even though they were encrypted in the
6986 reverse order. For this reason, MAC check failed. Now, this
6987 is fixed by not sending the Channel Key packet immediately but
6988 putting it to queue. However, this is more fundamental problem:
6989 packets that are in queue should actually not be encrypted
6990 because packets that are sent immediately gets encrypted
6991 actually with wrong IV (and thus MAC check fails). So, packets
6992 that are in queue should be encrypted when they are sent to
6993 the wire and not when they put to the queue.
6995 However, the problem is that the current system has not been
6996 designed to work that way. Instead, the packet is encrypted
6997 as soon as possible and left to the queue. The queue is then
6998 just purged into wire. There won't be any fixes for this
6999 any time soon. So, the current semantic for packet sending
7002 o If you send packet to remote host and do not force the send
7003 (the packet will be in queue) then all subsequent packets to the
7004 same remote host must also be put to the queue. Only after the
7005 queue has been purged is it safe again to force the packet
7008 o If you send all packets immediately then it safe to send
7009 any of subsequent packets through the queue, however, after
7010 the first packet is put to queue then any subsequent packets
7011 must also be put to the queue.
7013 Follow these rules and everything works fine.
7015 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7017 * Added new function silc_server_remove_clients_by_server to
7018 remove all client entries from ID list when the server connection
7019 is lost. In this case it is also important to invalidate all
7020 client entires as they hold the invalid server entry. This
7021 fixes fatal bug when server has lost connection and will reconnect
7024 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7026 * Made some sanity checks to silc_server_daemonise like to check
7027 whether the requested user and group actually exists.
7029 * Added sanity check to SKE's silc_ske_responder_finish to check
7030 that the public and private key actually is valid.
7032 * Invalidate the client's nickname when receiving Replace ID
7033 packet and the Client ID is being replaced. This means that the
7034 server will query the nickname if someone needs it (client)
7037 * Sort the ID Cache in client library when the ID Cache data
7038 has changed (needs sorting).
7040 * Do not allow for SILC client to create several connections to
7041 several servers. The client does not support windows right now
7042 and generating multiple connections causes weird behaviour.
7044 Irssi-silc client does support windows and can handle several
7045 connections without problems, see: www.irssi.org and SILC plugin.
7047 * Fixed some places where client was added to the IDList. The
7048 rule of thumb is following (in order to get everything right):
7049 If the client is directly connected local client then the
7050 `connection' argument must be set and `router' argument must be
7051 NULL to silc_idlist_add_client function. If the client is not
7052 directly connected client then the `router' argument must
7053 bet set and the `connection' argument must be NULL to the
7054 silc_idlist_add_client function.
7056 * The funtion silc_server_packet_send_local_channel actually did
7057 not check whether the client was locally connected or not. It
7058 does that now. Fixed a bug related to LEAVE command.
7060 * Fixed Remove Channel User payload parsing bug in server's
7061 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
7063 * The server's silc_server_save_channel_key now checks also the
7064 global ID list for the channel as it might not be in the local
7065 list. Fixed a bug related to LEAVE command.
7067 * Is this the end of the [<unknown>] buglet that has been lurking
7068 around for a long time? A little for loop fix in server's
7069 silc_server_command_whois_parse that is used by both IDENTIFY
7070 and WHOIS command. At least, this was a clear bug and a cause
7071 of one type of [<unknown>] buglet.
7073 * WHOIS and IDENTIFY commands call the function
7074 silc_server_command_[whois/identify]_check function even if
7075 we are not router server.
7077 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7079 * Added --with-gmp configuration option. If set the GMP
7080 is always compiled in the SILC source tree. If not set then
7081 it is checked whether the system has the GMP3 installed. If
7082 it has then the GMP won't be compiled (the system's headers
7083 and library is used), if it doesn't have it then the GMP is
7084 compiled in the SILC source tree.
7086 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7088 * Changed RSA private exponent generation to what PKCS #1
7089 suggests. We try to find the smallest possible d by doing
7090 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
7091 not security fix but optimization.
7093 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7095 * Added new config entry [Identity] to fork the server and run
7096 it as specific user and group. A patch from Bostik.
7098 * Imported Dotconf configuration library into lib/dotconf.
7099 This will be used to create the SILC configuration files later.
7100 It will appear in the distsribution after this commit.
7102 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7104 * A big code auditing weekend happening. Auditing code for
7105 obvious mistakes, bugs and errors. Also, removing any code
7108 Removed files for being obsolete:
7110 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
7111 inline in the file lib/silcutil/silcbuffer.h)
7113 o lib/silcutil/silcbufutil.c (the header has inline versions)
7115 Changed code to fix possible error conditions:
7117 o The buffer formatting routines now check that the destination
7118 buffer really has enough space to add the data. This applies for
7119 both buffer formatting and unformatting
7120 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
7121 unformatting was changed to accomodate following rules:
7122 XXX_*STRING_ALLOC will allocate space for the data into the pointer
7123 sent to the function while XXX_*STRING will not allocate or copy
7124 the data into the buffer. Instead it sets the pointer from the
7125 buffer into the pointer sent as argument (XXX_*STRING used to
7126 require that the pointer must be allocated already). This change
7127 makes this whole thing a bit more consistent and more optimized
7128 (note that the data returned in the unformatting with XXX_*STRING
7129 must not be freed now). The routines return now -1 on error.
7131 o Tried to find all code that use buffer_format and buffer_unformat
7132 and added return value checking to prevent formatting and
7133 especially unformatting errors and possible subsequent fatal
7136 o Changed ske->x and ske->KEY to mallocated pointers in
7137 lib/silcske/silcske.h. Fixed possible data and memory leak.
7139 o Added return value checking to all *_parse* functions. Fixed
7140 many memory leaks as well.
7142 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
7143 so that buffer overflows would not happen. All code now also
7144 checks the return value as it can fail.
7146 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7148 * Added reconnection support to server if the normal server looses
7149 its connection to the router (for example if router is rebooted).
7150 The server performs normal reconnection strategy implemented
7151 to the server. Affected file silcd/server.c.
7153 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7155 * Added new packet type SILC_PACKET_SET_MODE that is used to
7156 distribute the information about changed modes (for clients,
7157 channels and clients channel modes) to all routers in the
7158 network. Updated the protocol specification accordingly.
7160 Added functions into silcd/packet_send.c and
7161 silcd/packet_receive.c: silc_server_send_set_mode,
7162 silc_server_set_mode.
7164 Added new files silcmode.[ch] into lib/silccore that implements
7165 the encoding and decoding of Set Mode Payload. Added new type
7166 SilcSetModePayload. Moved the definitions of different modes
7167 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
7169 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7171 * Oops, a little mistake in server's connection authentication
7172 protocol. The protocol is not ended with FAILURE but with
7173 SUCCESS if the authentication is Ok. :) Affected file is
7176 * Implemented NICK_CHANGE notify handling in server in the file
7177 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
7178 the local clients on the channel. After the changing nickname
7179 in router environment snhould work and the [<unknown>] nickname
7180 should appear no more.
7182 The silc_server_replace_id function that receives the Replace ID
7183 payload now sends the NICK_CHANGE notify type also in the file
7184 silcd/packet_receive.c
7186 * Changed WHOIS and IDENTIFY command to support the maximum amount
7187 of arguments defined in protocol specs (3328 arguments). This
7188 fixed a bug that caused problems when there were more than three
7191 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7193 * Added extra parameter, command identifier, to the
7194 silc_client_send_command so that explicit command identifier
7197 Changed that ID list routines uses specific command identifier
7198 when sending WHOIS/IDENTIFY requests to the server so that they
7199 can be identified when the reply comes back.
7201 Affected files lib/silcclient/command.[ch],
7202 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
7204 * Added `sender' argument to silc_server_packet_send_to_channel
7205 to indicaet the sender who originally sent the packet to us
7206 that we are now re-sending. Ignored if NULL. Affected file
7207 silcd/packet_send.[ch].
7209 * Added some server statistics support in silcd/server_internal.h
7210 SilcServerStatistics structure and around the server code. Also
7211 send some nice statistics information when client is connecting
7214 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7216 * Fixed channel ID decoding in server's JOIN command reply in
7217 silcd/command_reply.c
7219 * Fixed braodcasting of replace ID payload to not to send it if
7220 we are standalone server in silcd/packet_receive.c.
7222 * Fixed all channel message sending routines to not to send
7223 packets to clients that has router set, since they are routed
7224 separately in the same function earlier. Affects file
7225 silcd/packet_send.c and all channel packet sending functions.
7227 * In USERS reply, res_argv[i] are not allocated, the table
7228 is allocated. Thus changed that free the table, not its
7231 * In server's whois_check and identify_check if the client is
7232 locally connected do not send any WHOIS commands - they are not
7235 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7237 * Fixed some minor bugs in client when sending WHOIS command. The
7238 arguments was in wrong order.
7240 * Removed statis function add_to_channel from server in
7241 silcd/command.c that was previously used with the joining but
7244 * Tested USERS command in router environment successfully with two
7245 routers, two servers and two clients.
7247 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7249 * Reorganized the USERS command and command reply in client library
7250 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
7251 When the command is given by user we register a pending command
7252 callback that will reprocess the command after the reply has been
7253 received from the server. When reprocessing the packet we then
7254 display the information. Thus, the USERS information is displayed
7255 now in the command callback instead of in the command reply
7256 callback. The processing of the command is same as previously
7257 when server has sent the command reply in the JOINing process.
7259 * Added to USERS command in silcd/command_reply.c to join the client,
7260 we didn't use to know about, to the channel after we've created
7261 a client entry for it. Also, for clienet we did know already still
7262 check whether it is on the channel or not and add it if not.
7264 * Removed silc_server_command_join_notify as the function and its
7267 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7269 * Changed the client's pending command handling to the same as the
7270 server's pending command handling. It is also now possible to
7271 execute command reply functions from other command reply
7272 function as the function callbacks for commands and command
7273 replies are one and same. The pending commands are not static
7274 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
7275 in client connection context. Thus, pending commands are server
7276 connection specific as it is convenient.
7278 Changed the function silc_client_command_pending and
7279 silc_client_command_pending_del and added new function
7280 silc_client_command_pending_check. Removed the
7281 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
7284 * Added cmd_ident, current command identifier, to the client
7285 connection context in lib/silcclient/client.h to keep track on
7286 command identifiers used in command sending. Client's command reply
7287 function handling now supports the mandatory command identifiers.
7289 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
7290 funtions in client to fully support pending command callbacks.
7292 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
7293 as one of the arguments to the application in the command reply
7296 * NOTE: The FORWARDED flag is depracated. It used to be depracated
7297 before first releasing SILC but came back. Now it is removed again
7298 and should come back nomore. The FORWARDED flag was used only
7299 by the JOINing procedure by forwarding the command packet to router.
7300 Now, the JOINing procedure has been changed to more generic (due
7301 to various router environment issues) and FORWARDED is not needed
7302 anymore for anything. The protocol specification is yet to be
7305 Now, removed silc_server_packet_forward from server and the flag
7306 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
7308 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7310 * Renamed NAMES command to USERS command. The NAMES was named that
7311 due to historical reasons. Now it is renamed. Also, rewrote
7312 parts of the USERS command. The nickname list is not sent anymore
7313 by the server. Only Client ID and mode lists are sent in the USERS
7314 command. Changed this also to the protocol specification.
7316 The client now resolves the names and stuff after it receives
7317 the USERS list from the server when joining to the channel.
7319 * WHOIS and IDENTIFY commands has been changed to support multiple
7320 Client ID's per command. One can now search for multiple users
7321 in the network by sending only one WHOIS or IDENTIFY command.
7322 Changed the code and the protocol specifications.
7324 * Removed silc_server_command_identify_parse and changed that IDENTIFY
7325 uses silc_server_command_whois_parse to parse the request. */
7327 * If normal server, do not parse the WHOIS and IDENTIFY requests
7328 before sending it to the router. Saves some time.
7330 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7332 * Fixed JOIN command on client library. Wrong number of arguments
7333 used to crash the client.
7335 * Added silc_server_channel_has_global function to check whether
7336 channel has global users or not.
7338 * Added silc_server_channel_has_local function to check whether channel
7339 has locally connected clients on the channel.
7341 * The silc_server_remove_from_one_channel now checks whether the
7342 channel has global users or not after given client was removed from
7343 the channel. It also checks whether the channel has local clients
7344 on the channel anymore. If it does not have then the channel entry
7345 is removed as it is not needed anymore.
7347 * The silc_server_notify now checks on JOIN notify whether the joining
7348 client is one of locally connected or global. If it is global then
7349 the channel has now global users on the channel and that is marked
7350 to the channel entry. Also, it now saves the global client to
7351 global list who is joining and JOINs it to the channel. This is
7352 for normal server, that is.
7354 Changed silc_server_send_notify_on_channel,
7355 silc_server_packet_relay_to_channel and
7356 silc_server_packet_send_to_channel check if we are normal server
7357 and client has router set (ie. global client) do not send the
7358 message to that client, as it is already routed to our router.
7360 * Implemented LEAVE notify type handling in silc_server_notify
7363 * Tested LEAVE command in router environment successfully. Tested
7364 with two routers, two servers and two clients.
7368 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
7370 * Implemented SIGNOFF notify type handling in silc_server_notify
7373 * silc_server_remove_id now removes the client entry from all channels
7374 it has joined and thusly sends SIGNOFF notify type.
7376 * Rewrote the NAMES list generation in server by removing two excess
7377 loops. The lists are created now inside one loop.
7379 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7381 * silc_server_remove_channel_user checks now also global list
7382 for channel and client.
7384 * silc_server_new_channel_user checks now both local and global
7385 list for channel and client. Fixed a bug in client id decoding.
7386 Used to decode wrong buffer.
7388 * silc_server_channel_message checks now both local and global
7389 list for channel entry.
7391 * Tested channel joining (hence JOIN) in router environment
7392 successfully. Tested with two routers, two servers and two
7395 * Tested channel message sending in router environment successfully.
7397 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7399 * Added silc_server_save_channel_key into server.[ch] to save the
7400 received channel key in Channel Key payload processing. It is
7401 also used in JOIN command reply handling.
7403 Equivalent function silc_client_save_channel_key added into
7404 client.[ch] into client library.
7406 * Changed JOIN command reply to send information whether the channel
7407 was created or not (is existing already) and the channel key
7408 payload. Changed protocol specs accordingly.
7410 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
7411 the request was sent by ID and not by nickname. Crashed on
7414 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7416 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
7417 now correctly save the received data.
7419 * silc_server_free_sock_user_data now notifies routers in the
7420 network about entities leaving the network.
7422 At the same time implemented functions silc_server_remove_id
7423 and silc_server_send_remove_id to receive and send REMOVE_ID
7424 packets. The packet is used to notify routers in the network
7425 about leaving entities. The ID removed will become invalid in
7428 * Added function silc_idlist_del_server into server. Removes and
7429 free's server entry from ID list.
7431 * silc_server_private_message function now checks, if we are router,
7432 that the destination ID really is valid ID, naturally.
7434 * In router when NEW_ID packet is received (for new client) the
7435 hash of the Client ID is saved in the ID Cache but the
7436 client->nickname is set to NULL, instead of putting the hash
7439 IDENTIFY command now also checks that client->nickname must be
7440 valid. If it is not if will request the data from the server who
7441 owns the client. Added new function
7442 silc_server_command_identify_check.
7444 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
7445 to set the command to already allocated Command Payload.
7447 * Tested private message sending in router environment with two
7448 routers, two servers and two clients. Fixed minor bugs and now
7451 * Fixed segfault from client's NAMES command. Used to crash if
7454 * Forwarded packets must not be routed even if it is not destined
7455 to the receiver. Changed server code comply with this.
7457 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7459 * Added `require_reverse_mapping' boolean value to ServerParams
7460 structure. If TRUE (not default) the server will require that
7461 the connecting host has fully qualified domain name.
7463 If the reverse mapping is not required and hostname could not be
7464 found the IP address is used as hostname.
7466 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7468 * Implemented version string checking to both client and server.
7469 The check is incomplete currently due to the abnormal version
7470 strings used in development version of SILC.
7472 * Changed all command functions in server to use the new
7475 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7477 * Changed char *data to unsigned char *data in ID Cache system to
7478 support binary data as ID Cache data. Changed code to support
7479 binary data in lib/silccore/idcache.c.
7481 * Renamed silc_server_packet_relay_command_reply to
7482 silc_server_command_reply as it is normal packet receiving
7483 function. Rewrote the function to accept command replys for
7484 servers and not only for clients.
7486 * Mark remote router always as registered server if we are connecting
7487 to it. Otherwise, commands sent by the router to us are ignored.
7489 * All ID List find routines now returns the ID Cache Entry pointer
7490 as well if requested.
7492 * WHOIS command works now in router environment, tested with two
7493 routers, two servers and two clients.
7495 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
7496 in router environment (as it is almost equivalent to WHOIS) but
7497 hasn't been tested thoroughly. Added new functions:
7499 silc_server_command_identify_parse
7500 silc_server_command_identify_send_reply
7501 silc_server_command_identify_from_client
7502 silc_server_command_identify_from_server
7504 * Disabled route cache adding because adding two different ID's with
7505 same IP replaces the old cache entry thus giving wrong route.
7506 The entry->router->connection is always the fastest route anyway
7507 so route cache may not be needed. Of course, new routes maybe
7508 established after receiving the ID when the entry->router->connection
7509 might not be anymore the most optimal.
7511 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7513 * Add route cache for received ID for fast routing.
7515 * Added silc_server_packet_route to route received packet on router
7516 that is not destined to us.
7518 * Renamed silc_server_get_route to silc_server_route_get.
7520 * Added id_string and id_string_len fields into SilcServer to
7521 include encoded ServerID for fast comparing without excess
7522 encoding of the ID's.
7524 * Cleaned up WHOIS command on server side. Added following static
7527 silc_server_command_whois_parse
7528 silc_server_command_whois_check
7529 silc_server_command_whois_send_reply
7530 silc_server_command_whois_from_client
7531 silc_server_command_whois_from_server
7533 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
7534 arguments in command replies. All command functions should be
7535 updated to use this macro.
7537 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7539 * Minor typo fixes on command reply handling on server.
7541 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7543 * Added silc_server_command_add_to_channel internal routine to add
7544 the client to the channel after router has created the channel and
7545 sent command reply to the server.
7547 * Added generic silc_server_send_command to send any command from
7550 * Use static buffer with ID rendering instead of duplicating data.
7552 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7554 * Fixed a channel user mode bug when joining to a channel server gave
7555 everybody channel founder rights, oops.
7557 * We mark ourselves as the router of the incoming server connection
7558 if we are router ourselves. This way we can check in some packet
7559 sending functions whether it is locally connected server. For
7560 incoming router connections we put NULL.
7562 * For router sending packets locally means now always sending the
7563 packet cell wide; to local clients and local servers. For normal
7564 server sending packet locally means sending it to only local
7567 * Fixed the JOIN command to really work in router environment. If the
7568 channel is created it is always created by the router. Router is
7569 also responsible of making the initial joining to the channel,
7570 sending JOIN notify to the sending server and distributing
7571 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
7572 does not exist server doesn't do anything else but forward the
7573 command to the router which performs everything.
7575 * Added silc_server_send_channel_key function to send the Channel Key
7578 * Added silc_server_create_channel_key to create new channel key. The
7579 channel key is now re-generated everytime someone joins or leaves
7580 a channel, as protocol dictates. Note: channel->key_len is the
7583 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7585 * Splitted server.[ch] finally. Created now packet_send.[ch] and
7586 packet_receive.[ch] to separate packet sending and receiving
7587 routines. The server.[ch] now includes everything else including
7588 actual packet processing (writing and reading data) and other
7591 Renamed silc_server_private_message_send_internal to
7592 silc_server_send_private_message. The routine is still though
7593 used only to relay private messages as server does not send
7594 private messages itself.
7596 Renamed silc_server_new_channel to silc_server_create_new_channel
7597 and added new function sicl_server_new_channel that handles the
7598 incoming New Channel packet. Added also new sending function
7599 silc_server_send_new_channel to send New Channel Payload.
7601 * Added new function silc_server_notify to process incoming notify
7602 packet to the server/router. Server may then relay the notify
7603 to clients if needed.
7605 * Added new function silc_server_new_channel_user to process incoming
7606 New Channel User packet. Router will redistribute the packet and
7607 send JOIN notify to its local clients and locally connected servers
7608 if needed. Normal server will send JOIN notify to its local client
7609 on same channel when received this packet. Added also corresponding
7610 sending function silc_server_send_new_channel_user to sent the
7613 * Added boolean route argument to send_notif_to_channel and
7614 packet_send_to_channel functions to attempt to route the packet
7615 if it is TRUE and send only locally if it is FALSE.
7617 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7619 * silc_server_replace_id now broadcasts the received replace ID
7620 packet if it is not broadcast packet already. The router must
7621 broadcast to inform other routers about changed ID.
7623 * Added backpointer to server's router into SilcServer context in
7624 silcd/server_internal.h.
7626 * Fixed silc_server_packet_broadcast to send correct broadcast
7629 * The channel key is now distributed to the local client as soon
7630 as it is received from the router (in router environment) so that
7631 no other packet may be sent for the channel until client has
7634 * silc_server_remove_channel_user now broadcasts the received
7635 Remove Channel User packet if it is not broadcast packet already.
7636 The router must broadcast to inform other routers about removed
7639 * Added users field into SilcPacketContext that is a reference count
7640 of the context. One can increase the reference count by calling
7641 silc_packet_context_dup which is now changed to just increase the
7642 reference count instead of duplicating the data. The reference
7643 count is decresed by calling silc_packet_context_free that will
7644 free the data after the reference count hits zero.
7646 For now on the packet context and everything allocated into it
7647 (including the raw packet from network) must be freed by calling
7648 the new silc_packet_context_free function. Added also new function
7649 silc_packet_context_alloc that must be used now to allocate the
7650 context. This also means that if a routine is asynchronous from
7651 silc_[client/server]_packet_parse_type the packet context must
7652 be duplicated by calling silc_packet_context_dup. Otherwise it
7653 gets free'd after silc_[client/server]_packet_parse_type returns.
7654 Also, one must remember that if packet is duplicated then its
7655 reference count must be decresed by calling the free function as
7656 many times as it was duplicated.
7658 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7659 from both client and server.
7661 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7663 * Made joining to a channel working in router environment.
7665 * Cleaned up JOIN command on server side and create function
7666 silc_server_command_join_channel internal routine to make the
7669 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7671 * Changed silc_command_pending list to SilcDList. Also, added
7672 `ident' field to SilcServerCommandPending structure to identify
7673 the reply and to call correct callback.
7675 Added silc_server_command_pending_check function to replace the
7676 corresnponding macro. The silc_command_pending list is not
7679 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7680 to set identifier to previously allocated Command Payload. It
7681 is used to set identifier for command when resending Command
7684 * Added silc_command_payload_encode_payload to encode Command
7685 Payload buffer from SilcCommandPayload structure.
7687 * Added silc_argument_payload_encode_payload to encode Argument
7688 payload buffer from SilcArgumentPayload structure.
7690 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7692 * Changed WHOIS command to support router connection on server side.
7693 The whois request is always sent to router unless the server is
7694 standalone server. After server has received the reply from the
7695 router will it send the reply to the client.
7697 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7698 broadcast received broadcast packet. The function is used only
7699 by router. The broadcast packet is always sent to the router's
7702 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7703 render given ID to printable string, for log files for example.
7705 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7707 * Made basic router to router connections working. At least they
7708 can now connect to each other but nothing really works the way
7709 they are supposed - yet.
7711 * Added new initiator token to RouterConnection configuration
7712 file in silcd/serverconfig.[ch]. It is used to tell whether we
7713 are the initiator to the remote router or whether we'll expect
7714 the other end to connect.
7716 * Moved registering of listener task to silc_server_init, hence
7717 the server starts listenning as soon as it is run, even if it
7718 does not have connections to other routers. Let's see how well
7721 * Changed default connection retry timeouts for more suitable in
7724 * Removed cipher and such arguments from silc_idlist_add_client
7725 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7726 Added new function silc_idlist_add_data to add the keys and stuff
7729 * Added SilcIDListData structure and added it to SilcClientEntry
7730 and SilcServerEntry as their first field in the structure. This
7731 way we can explicitly cast the ID entries to the SilcIDListData
7732 structure and get common data for the entries. In past, we had
7733 to first check what type of connection it is and then cast it to
7734 correct ID entry type. Now, we can directly cast the opaque
7735 pointer to the SilcIDListData (no matter what ID entry it actually
7736 is) and get the data needed.
7738 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7740 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7741 in some circumstances even if threre were timeout tasks, though not
7742 IO tasks, but tasks anyway. Now fixed.
7744 * Defined SilcServerConnection structure to hold connection specific
7745 stuff about directly connected servers and routers. The definition
7746 is currently in silcd/server_internal.h. I thought about having
7747 a bit more important role fro this struct but for now it is used
7748 only when connecting to other server (or router actually).
7750 * Added connecting retry support in server when connecting to
7751 router(s). The retry feature implement exponential backoff
7752 algorithm. Also, added SilcServerParams structure to hold default
7753 parameters for server. For now, it include these retry settings
7754 and are hard coded. After server is moded to be as Silc Server
7755 Library this structure will be more important.
7757 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7759 * Changed client librarys channel->clients table to SilcList and
7760 changed code accordingly.
7762 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7764 * Changed client's channel table to SilcList and changed code
7765 accordingly. Also changed SilcChannelClientEntry to include back-
7766 pointer to the channel so that client entry can use that structure
7767 as list as well and we have fast cross-reference to the channel.
7768 This change dramatically decreased the complexity of channel
7769 handling with client entry and vice versa (removed one extra
7770 loop when searching for channel entry from many functions).
7772 * Changed server->sim from table to SilcDList and changed code
7775 * NAMES command can now be used from user interface. It will show
7776 the user list on the channel, neatly.
7778 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7779 Code now saves realname of the user if it becomes available.
7781 * Renamed configure.in to configure.in.pre and made ./prepare
7782 script to automatically add correct version string to
7783 configure.in which it creates from configure.in.pre.
7785 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7787 * NAMES command reply now shows users mode with the nickname when
7790 * Moved silc_client_ch[u]mode[_char] functions from
7791 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7792 place sucks, they are utility functions and should be in some
7795 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7797 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7800 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7804 * Added TRQ (efficient deque and list library) into lib/trq. This is
7805 a very good list library that is currently used in the SILC. Defined
7806 SilcList API over the library because I didn't like the API very
7807 much. See lib/trq/silclist.h for the API and examples of how to
7808 use the API. Fixed various places in the code to use the new
7809 SilcList API. The SilcList is meant for lists that has a structure
7810 already defined as a list. It is not suitable to add just some
7811 context to the list (in TRQ, the context is the list actually).
7813 So, I defined SilcDList that can be used for the purpose where
7814 predefined list structure does not exit. This can be used as
7815 such list. Now some context just can be added to the SilcDList.
7816 Currently this list is not used in the SILC just yet, though there
7817 are a lot places where this can replace dynamically allocated
7818 tables and I will fix these places, later, to use SilcDList.
7819 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7820 and use TRQ internally).
7822 Also fixed some annoying warning messages that the original TRQ
7823 code generated. Also minor changes to TRQ's Makefile.in.
7825 * Added support for querying by Client ID to both WHOIS and
7826 IDENTIFY commands into server, as required by the protocol.
7828 * Removed method function pointers from SilcBuffer structure. They
7829 weren't used to anything and just increased the context size for
7830 no good reason. This change also made silc_buffer_alloc and
7831 silc_buffer_free functions inline functions.
7833 * Disabled command flooding detection support until it's fixed so
7834 that it accepts commands in but does not execute them more than once
7837 * Added silc_net_localhost(), to return local hostname, into
7838 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7839 that must be initialized before calling silc_client_init.
7841 * Added new function: silc_server_send_notify_on_channels to send
7842 notify messages to all channels client has joined. It is assured
7843 that the message is sent only once per client.
7845 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7846 lib/silcutil/silcutil.[ch] as silc_format function. The new
7847 function is generic and is used by server as well, not only by
7848 the logging routines.
7850 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7851 the provided version string was not acceptable. Added new function:
7852 silc_ske_check_version into lib/silcske/silcske.h. The function
7853 must be implemented by the application (client or server) and it
7854 does not reside in the SKE library. The function checks the version
7855 string remote end sent.
7857 * Added back pointers (to opaque context and to SilcSocketConnection)
7858 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7860 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7861 duplicate packet context structure.
7863 * Changed `notify' client operation to send same arguments as client
7864 receives from server except for ID's. ID's are mapped to correct
7865 ID entry and that is returned. Also, if channel entry is not sent
7866 by server but the notify is for channel the channel entry is sent
7867 to application (otherwise application doesn't know that it is for
7868 channel (library gets it from packet's Destination ID)).
7870 * Added silc_client_remove_from_channels into client library to
7871 remove a client from all channels it has joined to. Used when
7872 received SIGNOFF notify from server. Added also new function
7873 silc_client_replace_from_channels to replace old ID entry with
7874 new ID entry on all channels. Used when received NICK_CHANGE
7877 * Fixed ID Cache list handling in silc_idlist_get_client in
7878 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7879 to get (or query) client by ID.
7881 * Updated TODO list.
7883 * Added connection authentication status message defined by the
7884 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7885 support for these into the code in client and server side.
7887 * Added generic function silc_client_send_command to send any command
7888 with variable argument list. Application should use this function
7889 to send commands if the command functions provided by the library
7890 does not suite for the application's user interface needs.
7892 * Added new `failure' client operation. Application is notified about
7893 received failure packet if client is executing a protocol. In this
7894 case the protocol's execution has failed.
7896 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7897 is required by the protocol.
7899 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7900 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7903 * Added status flag to SilcSKE object to indicate realtime status
7904 of the SKE protocol.
7906 * Application receives now exactly same command reply arguments as
7907 the library receives from server. However, if ID is received the
7908 corresponding ID entry is returned to the application (eg. Client
7909 ID is mapped to correct SilcClientEntry entry and that is returned).
7910 Changed command_reply client operation due to this change.
7912 * Changed all ID's in commands and in command replys as ID Payloads.
7913 Change affected both client and server side codes.
7915 All ID's sent in SILC network (with execption of ID's in SILC
7916 Packet header) are sent in ID Payload to support variable length
7919 * Server now notifies nick changes and notifies all clients on
7920 the channels about the new nickname (about the new Client ID,
7923 * Implemented CMODE command to change channel modes. Supports all
7924 channel modes defined by the protocol specs except ban and invite
7925 lists. (Also, private channel key mode is supported but support for
7926 setting private channel key in client is missing, thus, this mode
7927 has no effect on client side (except that server requires that the
7928 client uses private channel key and normal channel traffic does not
7931 Also, invite mode works per se, but INVITE command does not work
7932 yet correctly, so you can set channel as invite only channel but
7933 inviting clients to the channel does not work (it is yet to be
7934 thought what's the best way to do it).
7936 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7937 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7938 Implemented CUMODE command to change user's mode on the channel.
7939 Supports all modes defined by the protocol specs.
7941 * Added NAMES command reply to return users modes on the channel.
7943 * Removed unnecessary and slow ciphers from lib/silccrypt.
7945 * Set SO_KEEPALIVE option to connection sockets by default.
7947 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7949 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7950 redefined the Notify Payload into protocol specs.
7952 * Added silc_id_payload_parse_id to get ID directly from raw
7955 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7957 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7958 accept searching by Client ID as well.
7960 * Added support for LEAVE and SIGNOFF notify types in client library.
7962 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7963 to parse ID Payload from raw data.
7965 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7967 * Added flags parameter into silc_ske_assemble_security_properties
7968 function in lib/silcske/silcske.[ch].
7970 * Changed notify client operation to fit better for notify messages
7971 sent by server. The notify payload received from server is now
7972 passed to the application (after parsing it to SilcNotifyPayload).
7973 It is application's responsibility to retrieve the arguments
7974 from the payload and show the message the way it wants. The message
7975 sent by server is implementation specific.
7977 * Changed public keys to comply with the protocol specification.
7978 Old public keys are not supported anymore and are not compatible.
7980 * Removed nickname from Channel Payload as the latest draft removed
7981 it. The client must resolve the nickname from the NAMES command
7982 reply received when it joined the channel.
7984 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7986 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7988 * Fixed some errors in protocol specification drafts.
7990 * Created lib/silccore/silcnotify.c to implement Notify Payload
7991 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7992 generic payloads described by protocol specifications. The file
7993 includes implementations for ID Payload and Argument Payload.
7995 * Changed Command Payload implementation to use the new Argument
7996 Payload. Changed command_xxxx_payload to command_payload_xxxx
7997 to comply with SILC coding conventions.
7999 * Added suppport for Argument Payload handling in Notify Payload
8000 implementation as protocol requires it. Added the new support
8001 into server and client lib as well.
8003 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8005 * Added support for multiple nicknames on same channel. [n] is
8006 added locally to the nickname if there are more than one same
8007 nicknames on the channel.
8009 * Server now sends all nicknames that matched WHOIS request.
8010 Client also shows the list received from server.
8012 * Added TOPIC command to client side. User can now set and show
8013 current topic on channel.
8015 * Added MOTD command to client and server. Also, server sends the
8016 motd when client connects to the server.
8018 * Changed version strings to comply ISO 8601.
8020 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8022 * Fixed protocol error handling in client library. It should now
8023 cope even if the SKE fails for some reason.
8025 * Made new protocol specification drafts for submitting to IETF.
8027 * Implemented TOPIC command to server in silcd/command.c.
8029 * Added two new notify types into lib/silccore/silcnotify.h:
8030 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
8031 notify nickname change and topic setting/change on a channel.
8033 * API change of command_reply operation in client library. The
8034 application gets now the status type received from server as well.
8036 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8038 * Removed the function just added to lib/silcutil/silcschedule.[ch].
8040 * Cras fixed and optimized the packet handling even further and
8041 it should work now. Minor change to the prototype of function
8042 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
8044 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8046 * Added new function into lib/silcutil/silcschedule.[ch]:
8047 silc_schedule_with_fd to select() a specified fd. The function
8048 returns after timeout expires or data arrives or goes. The
8049 function is used by packet routines to wait that all data is
8050 received from network.
8052 * Fixed data reading from network in lib/silccore/silcpacket.c.
8053 The code now assures that all data is read from the fd and then
8054 continues packet processing. This was a bug fix since the code
8055 used to drop some data in some circumstances.
8057 * Added new function into lib/silcclient/client.[ch]:
8058 silc_client_start_key_exchange to start key exchange after
8059 connection has been established to server. The code internally
8060 now uses this funtion but its main purpose was to provide it
8061 for applications that perform their own connecting. After
8062 application has created a connection it merely calls this
8063 function to start the key exchange between client and server.
8064 The library takes care of everything else after that.
8066 Updated also lib/silcclient/README to explain the usage of
8069 * Do not send to application information that connection has
8070 been established. Application gets notified it by connect
8073 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8075 * Applied cras's patch to add silc_schedule_one function. The
8076 function runs scheduler once and returns.
8078 * Fixed the scheduler after cras messed it up. The timeout
8079 handling works now as it's supposed to work.
8081 * Added into lib/silccore/ silcnotify.h to include notify
8082 message types support. Changed silc_server_send_notify*
8083 functions, in server.[ch], to support those new notify types.
8084 Added the support for the notify types into client library,
8085 as well. Added new notify client operation into ops.h in
8088 * Changed silc_server_packet_send_to_channel to send normal
8089 packets instead of just channel message packets. The function
8090 is now used to send the notify packets to channels. It is not
8091 used to send channel message packets anymore, as server never
8094 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
8095 va_arg()s as it seems to require it nowadays. I guess, if SILC
8096 is compiled with older va_arg() the new code should work anyway.
8098 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8100 * Splitted core library. Core library (lib/silccore) includes
8101 now only SILC protocol specific core (and common) components.
8102 Created new utility library (lib/silcutil) that includes more
8103 generic purpose stuff. The stuff for util library was taken
8104 from the old core library. This was minor and easy split.
8106 * Created SILC Client Library (lib/silcclient) that includes
8107 implementation of the SILC client without user interface. This
8108 was major move from silc/ directory. The code has been changed
8109 so that it is transparent towards the user interface. The
8110 silc/ directory includes now the same user interface as before
8111 and it uses the new client library. Read lib/silcclient/README.
8112 Basicly, the client library performs everything else related
8113 to SILC except user interface handling. Also, configuration
8114 files are considered to be part of user interface and library
8115 does not handle them.
8117 This change also changed a lot of structures, function naming etc.
8118 Most important change was that SilcClientWindow object was
8119 renamed to SilcClientConnection in the client library. Created
8120 also new file lib/silcclient/ops.h. Also added new files
8121 silc/local_command.[ch] and silc/client_ops.[ch].
8123 All these changes were made to make it easier for user interface
8124 designers to create what ever user interface for the SILC client
8127 It is also expected that the server will be moved to lib
8128 directory as well and SILC Server Library will be created;
8129 sometimes in the future.
8131 * Removed Local commands from lib/silccore/silccommand.h as
8132 they are application specific and new client library does not
8133 handle any of those anymore.
8135 * Several functions moved to lib/silcutil/silcutilc.[ch] from
8136 old client implementation in silc/.
8138 * Added support for callback functions in SILC_LOG_* macros.
8139 Application can now set its own callbacks that will be called
8140 instead of using the default functions that will always print
8141 the debug messages to stderr (or stdout). Also, debugging can
8142 now be disabled by setting silc_debug to FALSE and re-enabled by
8143 setting it to TRUE. Note, that logging will still work even
8144 if debugging is disabled.
8146 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
8147 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
8148 silc_log_reset_debug_callbacks.
8150 * To enable debugging in silc client one must give now -d
8151 option on command line.
8153 * Changed silc_schedule_init to automatically allocate task queues
8154 if they are not allocated before calling it.
8156 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8158 * Added GMP 3.1 into math library.
8160 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8162 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
8163 a channel in SILC network. The packet is used by servers and
8164 routers to notify other routers that user has left a channel.
8165 This little feature was missing until now. Added the feature
8166 to protocol specification as well.
8168 Added functions: silc_server_send_remove_channel_user and
8169 silc_server_remove_channel_user into server.[ch].
8171 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
8172 lib/silccore/silcpacket.h. However, they are not implemented
8175 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8177 * Fixed joining to a channel and sending channel messages
8178 between server and router. The channel message sending should
8179 now work inside a cell.
8181 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8183 * Fixed the private message sending between server and router.
8184 The private message sending should now work inside a cell.
8186 * Added silc_server_replace_id into server.[ch] to replace
8187 existing ID in the SILC network.
8189 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
8190 and silc_idlist_replace_server_id into idlist.[ch] in server.
8192 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8194 * Fixed the server to server connections. Server can again now
8195 connect to router. Router to router connections probably does
8198 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8200 * Added dynamic protocol registering support. Now protocols can
8201 registered and unregistered on the fly. Patch by cras.
8203 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8205 * Added lib/contrib directory to hold routines that some platforms
8206 don't have but are needed by SILC.
8208 * Added getopt.c, getopt1.c and getopt.h from GNU C library
8209 into lin/contrib to provide getopt() and getopt_long() for
8210 those who don't have it.
8212 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8214 * Added AWAY command to client. When away message is set and
8215 client receives a private message packet the client automatically
8216 replies to the sender with the away message.
8218 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
8219 bug seemed to be the cause of recent problems when compiling
8222 * Added version detection support to SKE protocol specification
8223 and added the new changes to the SKE implementation as well.
8224 There were other minor changes in the SKE protocol as well.
8226 Many changes in lib/silcske/silcske.[ch] and in
8227 lib/silcske/payload.[ch].
8229 * Added ^U functionality, clear input line. Patch from cras.
8231 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8233 * Mainly small bugfixes on core library. Fixed some debugging
8234 logging and buffer overflow in silclog.c.
8236 * Updated config.sub and config.guess on the distribution tree.
8238 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8240 * Added command lagging support in server. Client may execute
8241 commands now only once in two seconds.
8243 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8245 * Optimized packet reception. MAC computation and checking is now
8246 also more optimized. A lot previously duplicated code is now
8247 used as generic by both client and server.
8249 * Fixed key pair generation in clientutil.c
8251 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8253 * Added into lib/silccore/silcbufutil.[ch] new function;
8254 silc_buffer_realloc.
8256 * Moved generic packet sending/encryption functions to
8257 lib/silccore/silcpacket.[ch] from client and server. Some
8258 rewriting of the functions.
8260 * Moved all generic packet reception/decryption functions to
8261 lib/silccore/silcpacket.[ch] from client and server. The
8262 packet processing is now much cleaner in both client and server.
8263 These were major changes in both client and server.
8265 * Created many common functions in server to do packet sending.
8266 Previously code were duplicated a lot, this has been removed
8269 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8271 * Rewrote major parts of the ID cache system. Don't know
8272 whether it is better now or not but at least the API is more
8275 * Major rewrite on ID cache stuff on client because of the ID
8276 cache API changes. Added idlist.c to client.
8278 * Also major rewrite on ID cache stuff on server as well.
8279 Major rewrite of idlist.[ch]. SilcXXXList's are now named
8280 SilcXXXEntry's. We won't keep anymore idlist specific pointers
8281 in hand, instead they are all put into the ID cache system now.
8282 All server_idlist_* routines uses ID cache now instead of
8283 traversing its own lists (those lists does not exist anymore).
8284 SilcIDList though still exists. Also, SilcXXXEntry's are
8287 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8289 * Finally made the SKE implementation compliant to the protocol
8290 specification. All mp integers are now binary encoded as
8291 opposed being HEX encoded.
8293 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
8296 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
8297 functions: silc_[encode/decode]_pem. Also added function
8298 silc_encode_pem_file to PEM encode with newlines ('\n') for
8301 * SILC public keys are now encoded either PEM or binary. Same
8302 option is for private keys as well. By default private keys
8303 are binary encoded and public keys PEM encoded. Silly HEX
8304 encoding were removed.
8306 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
8307 function to create fingerprints.
8309 * Fixed a bug in SHA1; does not change the original data anymore.
8311 * Partly implemented INFO command on client and server side.
8312 Fixed CLEAR command. Changes to SERVER command; show current
8313 server(s) when giving command without arguments. Added
8314 VERSION command to client.
8316 * Added check to server that unregistered connections cannot
8317 execute commands (unless it is specificly allowed).
8319 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8321 * Fixed screen refresh.
8323 * Fixed channel joining bug from client. On some circumstances
8324 client tried to join to a channel it had already joined.
8326 * Added public key verification process into client's protocol.c.
8327 The client now verifies the public key from user and saves
8328 it into ~./silc/serverkeys/ directory.
8330 Added into: clientutil.[ch]: silc_client_verify_server_key.
8332 * Changed SKE protocol's silc_ske_initiator_finish function
8333 to accept callback function that verifies the received public
8334 key. Removed old silc_ske_verify_public_key function.
8336 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8338 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
8339 silc_pkcs_private_key[_data]_set.
8341 * Made the password and public authentication more cleaner in
8342 server's protocol.c.
8344 * Removed historic and obsolete protocol `channel_auth' from
8345 both client and server.
8347 * Removed wrong way of sending command status messages from
8348 server to client in server's command.c. The old way violated
8349 protocol specification.
8351 Changes to silccore/silccommand.[ch]: removed
8352 silc_command_encode_status_payload -> not needed anymore,
8353 changed silc_command_encode_payload_va to accept extra
8354 argument on variable argument list. The argument type must
8355 now be provided to the function. Also, added new function:
8356 silc_command_encode_reply_payload_va which is same as
8357 normal command_encode_payload_va except command status type
8358 is provided as extra argument.
8360 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8362 * Added ~./silc directory handling. The directory includes the
8363 public and private keys for the client.
8365 Added silc_client_check_silc_dir, silc_client_create_identifier
8366 and silc_client_load_keys.
8368 * Implemented SILC protocol compliant public key. Added public
8369 and private key saving to and loading from files.
8371 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
8372 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
8373 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
8374 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
8375 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
8377 Implemented: silc_pkcs_save_[public/private]_key[_data] and
8378 silc_pkcs_load_[public/private]_key.
8380 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8382 * Added silc_server_get_route (route.[ch]) to get connection
8383 data for the fastest route for given ID.
8385 * Implemented INVITE command on client and server. The command
8386 were re-defined in the SILC Protocol Specification and the
8387 implementation now complies with the specification.
8389 * Implemented PING command on client and server.
8391 * Implemented NAMES command on client and server. The server side
8392 supports currently only normal server not router server yet.
8393 Some changes to NAMES definition in SILC protocol specification.
8395 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8397 * Implemented LEAVE command on client and server.
8399 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
8400 again. This change was made to the protocol as well. Server
8401 should not violate the protocol specification anymore.
8403 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8405 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
8406 was tested. SOCKS4 was not but should work anyway.
