508 to client and server. Protocol TODO #6. Affected files are
509 silcd/packet_receive.c, server_util.c, lib/silcclient/command.c,
510 lib/silcclient/client_channel.c, lib/silccore/silcmode.h.
512 Added new options m and M to CMODE command in Irssi SILC
513 client to set these modes.
515 * Deprecated all administrative commands from SILC protocol
516 since they are highly implementation specific commands.
517 Updated protocol specs. Moved the old commands in
518 implementations to private range of command types. Affected
519 files are silcd/command.c, lib/silcclient/command.c and
520 lib/silcclient/command_reply.c. Protocol TODO #8.
522 * Fixed a bug in server where sending unknown command crashes
523 the server. Affected file silcd/command.c.
525 Wed Apr 3 09:57:47 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
527 * Added SILC_PROTOCOLVERSION macro to check protocol version
528 of a socket connection. The affected file is
529 lib/silcutil/silcsockconn.h.
531 * Added better error logging in rekey protocol. Affected file
534 * Do not check public key types in SKE during rekey. Affected
535 file lib/silcske/payload.c.
537 * Fixed the rekey protocol with PFS, which was totally broken.
538 Affected file silcd/protocol.c.
540 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
542 * Some client implementations quit network by doing first LEAVE
543 and then immediately SIGNOFF (like Bombyx). We now do check
544 after a short time after LEAVE notify and check whether the
545 client is still valid after LEAVE, and if not we remove it from
546 cache. Affected file is lib/silcclient/client_notify.c.
548 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
550 * Merged version 1.1.4 of zlib. Even if it not currently in use,
551 it's good not to have security holes here.
553 * Fixed a negative refcount situtuation for the config context.
554 Affected file is silcd/serverconfig.c.
556 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
558 * ROBOdoc documented lib/silcutil/silcutil.h.
560 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
562 * Optimized even more the SilcPacketContext structure. Now
563 totally saved 16 bytes of memory per context after optimization.
564 Affected files are lib/silccore/silcpacket.[ch].
566 * Made strict checks for valid SILC IDs. Affected file is
567 lib/silccore/silcid.c.
569 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
571 * Changed the object argument for silc_cipher_register,
572 silc_hash_register, silc_hmac_register and silc_pkcs_register
573 to const. Affected files are lib/silccrypt/silccipher.[ch],
574 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
576 * Changed the silc_get_username and silc_get_real_name to
577 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
579 * Fixed the Irssi SILC Client to use the silc_get_username and
580 silc_get_real_name insted of glib routines since the glib
581 routines only corrupt stack. Fixes the Irssi SILC to work in
582 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
584 * Fixed the Irssi to not use g_get_home_dir since it crashes
585 or returns garbage on cygwin and corrupts stack. Added function
586 get_home_dir to Irssi routines. Affected files are
587 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
589 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
591 * Made some structure optimizations. SFTP memory FS MemFSEntry
592 entry structure. Optimized SilcTask structure. Optimized
593 SilcPacketContext structure.
595 Affected files lib/silcsftp/sftp_fs_memory.c,
596 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
598 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
600 * And yet again reverted back the config thing since Johnny
601 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
604 * Fixed memory leaks from config object. Affected files are
605 silcd/serverconfig.[ch].
607 * Added support for adding new connections to the server in rehash.
608 After rehash they take effect.
610 Added support for changing the maximum allowed connections in
611 rehash. The number can grow but going smaller is not supported.
613 Added function silc_server_num_sockets_by_remote to the
614 silcd/server_util.[ch].
616 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
618 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
620 * Added preliminary checking during config parsing for a valid
621 public/private key and removed further checks in the code.
622 Affected files are silcd/serverconfig.[ch], server.c.
624 * Moved functions silc_server_drop() and silc_server_daemonise()
625 from server.c to silcd.c since they are stricly related to
626 the application activity.
628 * Reverted a small part of the automatic ref/unref since
629 it caused a double unref in some situations. Affected
630 files are silcd/silcd.[ch], server.c, serverconfig.c.
632 * Added some .cvsignore files in the lib directory.
634 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
636 * Fixed silc_net_gethostbyaddr to correctly resolve by
637 address. Affected file lib/silcutil/silcnet.c.
639 * Fixed the notify relaying to client. The HMAC to be used
640 with relayed packets ws wrong and caused decryption failure
641 at the client end. Affected file is silcd/packet_receive.c.
643 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
645 * Created new branch silc_protocol_1_0_branch.
647 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
649 * Changed the silc_server_config_* routines to be SilcServer
650 independent. They are now officially application specific code
651 and not part of generic server implementation. Affected files
652 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
654 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
656 * Added automatic referencing of config context in the
657 silc_server_config_alloc, and automatic unreferencing in the
658 silc_server_config_destroy. Affected files are
659 silcd/serverconfig.[ch], silcd/silcd.c.
661 * Fixed the silc_log_quick handling in the logging routines.
662 It didn't log quickly when it was TRUE. Affected file is
663 lib/silcutil/silclog.c. Also the flush delay was set even
664 if it was 0 in config file. Affected file is
665 silcd/serverconfig.c.
667 * Added support for changing key pair of the server in rehash.
668 Affected file silcd/server.c.
670 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
672 * Fixed the TOPIC_SET notify to not cras. It changed the topic
673 too early, before getting the channel entry. Affected file
674 is silcd/packet_receive.c.
676 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
678 * Added functions silc_server_config_[ref/unref], these are used
679 to prevent that the config object is destroyed.
681 No longer directly affect global variables silc_log_quick and
682 silc_log_delay, they are first cached inside the config object
683 and then applied with silc_server_config_setlogfiles().
685 silc_server_config_set_defaults() is now internal to
686 serverconfig.c, there are no reasons to show this internal stuff
689 Affected files are silcd/serverconfig.[ch].
691 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
692 fprintf's to stderr, since some code may be executed again after
693 the server went into the background. Affected files are
696 * Added rehash support. Added function silc_server_rehash() that
697 will perform all the basic tasks of the rehashing procedure.
699 * Added command line option `-x, --hexdump'. This will enable the
700 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
701 The option `--hexdump' implies `--debug'.
703 * Fixed a bad bug in the logging APIs (silcutil library) where
704 the application would crash after calling silc_log_reset_all().
706 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
708 * Fixed the KICKED notify handling in client library to
709 correctly remove the channel and all entries from the
710 channel when I was kicked. This bug crashed the client.
712 Fixed yet another but in KICKED notify handling to remove
713 the kicked client correctly from the channel.
715 Affected file is lib/silcclient/client_notify.c.
717 * Fixed a minor bug in looking up correct client entry
718 in KICKED notify in server. Affected file is
719 silcd/packet_receive.c.
721 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
722 sources correctly to distribution. Fixes --with-gmp option.
724 * Removed the manual rehashing from ID Cache, and changed it
725 to use the SILC Hash Table's auto rehash feature. Affected
726 file is lib/silccore/silcidcache.c.
728 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
730 * Fixed a bug in the silc_client_nickname_format function that
731 handles the multiple same nickname formatting. Two clients
732 with same nickname caused problems after the first one left
733 and rejoined. It didn't format the nickname correctly.
734 Affected file is lib/silcclient/idlist.c.
736 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
738 * Don't change the topic if olod topic is same as new one.
739 Affected file is silcd/packet_receive.c.
741 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
743 * Added cross-reference support to the SILC Documentation
744 generator. All types across all HTML files are now cross-
745 referenced. Affected files util/robodoc/generator.c and
746 scripts/silcdoc/silcdoc.
748 * Added file lib/silcutil/silctypes.h to include all the
749 arithmetic type definitions and some macros. Removed
750 includes/bitmove.h and moved macros to silctypes.h.
752 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
754 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
756 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
758 * Added `type' argument to silc_id_payload_parse_id function which
759 now returns the type of the ID to the sent pointer. Affected
760 file is lib/silccore/silcid.[ch].
762 * Added check for CMODE_CHANGE notify type that mode change is
763 allowed by the sender. Affected file silcd/packet_receive.c.
765 * Added check for CUMODE_CHANGE notify type that mode change is
766 allowed by the sender. Affected file silcd/packet_receive.c.
767 Added the ID type as CUMODE_CHANGE notify type as argument
768 to the `notify' client operation. Affected files are
769 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
771 * Added function silc_client_add_server to the client library.
772 Added support for resolving also channel and server info when
773 received unknown entity in notify packet. Affected files are
774 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
776 * Added function silc_command_get_status to return the command
777 status from the command reply's argument payload. Affected files
778 are lib/silccore/silccommand.[ch].
780 * Added check for KICKED notify type that the kicking is
781 allowed by the client. Affected file silcd/packet_receive.c.
783 * Created function silc_get_input which can be used to get input
784 (echo on or off) from user on command line. Affected files are
785 lib/silcutil/silcutil.[ch].
787 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
789 * Optimized silc_server_packet_relay_to_channel function.
790 Added new function silc_channel_message_payload_encrypt which
791 can be called directly if channel message payload needs to
792 be encrypted and is already encoded (no need to call _encode
793 function). Packet relaying is now done by router without any
794 extra memory allocations. Affected files are
795 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
798 * Fixed the INVITE notify handling. It took wrong arguments
799 as invite list and invite delete. Affected file is
800 silcd/packet_receive.c.
802 * Added check for TOPIC_SET notify type that the topic change is
803 allowed by the client. Affected file silcd/packet_receive.c.
805 * Added check for INVITE notify type that inviting is allowed by
806 the client. Affected file silcd/packet_receive.c.
808 * Changed the silc_server_client_on_channel to return the
809 SilcChannelClientEntry as well. Moved the function
810 silc_server_check_cmode_rights to server_util.[ch].
811 Affected files are silcd/server_util.[ch], silcd/command.c.
813 * Added function silc_server_check_umode_rights to check whether
814 changing client's user mode is allowed. Added check for
815 UMODE_CHANGE notify type that the umode change is allowed
816 by the client. Affected files are silcd/server_util.[ch],
817 silcd/packet_receive.c and silcd/command.c.
819 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
821 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
822 ID length. It ignored that ID can be IPv6 based as well.
823 Affected file lib/silccore/silcpacket.h.
825 * Fixed the silc_id_id2str and silc_id_str2id to take the
826 IPv6 address offset's into consideration. Affecte file is
827 lib/silccore/silcid.c.
829 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
831 * Fixed the internal Unix scheduler functions to check for
832 NULL context they may receive. The affected file is
833 lib/silcutil/unix/silcunixschedule.c.
835 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
837 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
838 can specify different directory with --home command line
839 parameter. Affected files irssi/src/silc/core/client_ops.c,
842 * SILC-specific commands aren't now executed if the active server
843 isn't of SILC-type, so there won't be problems with having
844 IRC and SILC protocol support in same client. Affected files
845 irssi/src/silc/core/silc-channels.c, silc-servers.c,
848 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
850 * Improved the signal support in SILC Schedule. Added new
851 function silc_schedule_signal_call which is used by application
852 to mark a signal to be called. It is now safe to perform
853 any kind of tasks in signal callbacks since it is guaranteed
854 that the application specified signal callback is called
855 after the signal is over. Affected files are
856 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
858 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
860 * Added `name' field to SilcChannelPrivateKey to represent
861 application given name for the key. Moved also the context from
862 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
863 Added the `name' argument also to the function
864 silc_client_add_channel_private_key.
866 Added function silc_client_current_channel_private_key to set the
867 current channel private key in use.
869 Added "change" command to KEY command which can be used to change
870 the current channel private key. Bound the command also to
873 Also affected files lib/silcclient/client_channel.c,
874 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
876 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
878 * Added silc_rng_get_byte_fast function in to the
879 lib/silccrypt/silcrng.[ch].
881 * Changed the interface of silc_packet_assemble and the
882 silc_packet_send_prepare. If silc_packet_assmble is now
883 called the application does not call silc_packet_send_prepare
884 because the library will call it automatically. These
885 interfaces now also return a reference to the outgoing buffer
886 which includes the assembled packet, which the application can
887 use to encrypt the packet.
889 Affected files are lib/silccore/silcpacket.[ch],
890 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
891 silcd/packet_send.c, server_backup.c and packet_receive.c.
893 * Fixed a packet sending bug on very high load, where outgoing
894 packet queue wasn't handled correctly and packets got corrupted.
895 Affected files are lib/silcutil/*/silc*sockconn.c,
896 lib/silcclient/client.c and silcd/server.c.
898 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
900 * Added macro SILC_PACKET_DATALEN which can be used during
901 packet assembling to check whether the data to be added to
902 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
903 len is truncated until it fits it.
905 Added checks for maximum length of channel message payload and
906 private message payload also.
908 Added checks for maximum packet length in server and in
911 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
912 lib/silcclient/client.c, lib/silccore/silcchannel.c and
913 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
914 lib/silcclient/client_prvmsg.c.
916 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
918 * Added silc_server_packet_queue_purge call to the
919 silc_server_disconnect_remote to assure that all data in the
920 queue before disconnecting is sent to the network. Affected
923 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
925 * Added the deleting of server's own ID cache entry to the
926 silc_server_free function. Free also everything else that
927 has been allocated in silc_server_init. The affected file
930 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
932 * Added functions silc_parse_version_string, silc_version_to_num,
933 and silc_ske_parse_version to parse SILC protocol style version
934 strings. Affected files lib/silcutil/silcutil.[ch] and
935 lib/silcske/silcske.[ch].
937 * Added new configuration params: version_protocol, version_software
938 and version_software_vendor to specify what version the remote
939 host must at least be to be able to connect to server. The vendor
940 string can be regex matched too. Added new function
941 silc_server_connection_allowed to check maximum number of allowed
942 connections, and allowed versions for incoming connections.
943 Affected files are silcd/server.c, server_util.[ch] and
946 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
948 * Added preliminary support for signals in scheduler. The
949 signals we care about are now blocked always when the scheduler
950 is locked. This way we can synchronise the use of signal with
951 scheduler. It is guaranteed that when signal occurs the scheduler
952 is not locked, and thus new tasks can be safely added to the
955 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
956 to silc_schedule_internal_init and silc_schedule_internal_uninit.
957 Added new platform specific routines
958 silc_schedule_internal_signals_[un]block and
959 silc_schedule_internal_signal_[un]register.
961 Added new functions to SILC Schedule API:
962 silc_schedule_signal_[un]register. Each signal that application
963 is going to use should be registered to the scheduler.
965 Affected files are lib/silcutil/silcschedule.[ch],
966 lib/silcutil/*/silc*schedule.c.
968 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
970 * Check for unauthenticated client and server in the
971 silc_server_new_client and silc_server_new_server functions.
972 Affected file silcd/packet_receive.c.
974 * Added function silc_string_is_ascii to check whether given
975 string is 7-bit ASCII string. Affected files are
976 lib/silcutil/silcutil.[ch].
978 * Added function silc_id_is_valid_server_id into the
979 silcd/serverid.c and added checking for valid Server ID's in
980 silc_server_new_server. The Server ID must always be based
981 on the server's public IP address.
983 * Added logging of DISCONNECT packet message in the server.
984 Affected file silcd/server.c.
986 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
988 * Changed all library interfaces that use Global RNG to also
989 accept SilcRng as argument. Affected files are
990 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
991 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
992 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
993 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
996 * Added function silc_pkcs_generate_key to the
997 lib/silccrypt/silcpkcs.[ch] for applications so that they
998 don't need to do pkcs->pkcs->init calls anymore.
1000 * Remove SilcSocketConnection from the SFTP API since it really
1001 wasn't needed there. The application has the information
1002 saved in its contexts anyway and the SFTP layer doesn't need
1003 know about it. Affected files lib/silcsft/silcsftp.h and
1004 lib/silcsftp/sftp_[server/client].c.
1006 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
1007 The SilcSimContext is not SilcSim.
1009 * Fixed possible buffer overflows in silc_id_render in the
1010 lib/silcutil/silcutil.c.
1012 * On EPOC the global crypto module lists are not used at all
1013 in the crypto library. Added support for using the constant
1014 algorithm list on EPOC. Affected files are
1015 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
1018 * Fixed the handling of third parameter of KICKED notify, since
1019 it was mistakenly updated to SILC Protocol 1.0 even though it
1020 is to be included in 1.1. Since it is not in 1.0 it is not
1021 mandatory, and this fix now handles it only if it is provided,
1022 and it is not error if it is not provided. Affected file
1023 lib/silcclient/client_notify.c.
1025 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1027 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC

1062 file lib/silcutil/silcutil.[ch].
1064 * Added support for specifying multiple public keys for Client
1065 connection section in server configuration file. This makes it
1066 possible to accept multiple public keys from same host, or to
1067 make a section that accepts any incoming host, and have the
1068 accepted public keys listed in the section.
1070 Added functions silc_sever_[find/get]_public_key, added the

1183 old name went against naming convention. Applications now
1184 include "silcclient.h" instead of "clientlibincludes.h".
1185 Removed includes/clientlibincludes.h, it is redundant now.
1187 * Renamed includes/version.h to silcversion.h.
1189 * Added really preliminary support for OS/2 into the util
1190 library. Only thread & mutex API is implemented, others
1191 are still to be implemented. Created the lib/silcutil/os2/

1225 * Added `user_count' to the SilcChannelEntry which now tells the
1226 number of users on the channel. The user count is now saved
1227 in normal server of global channels as well. Affected files
1228 silcd/server.c, idlist.h, packet_receive.c and command.c.
1230 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
1231 include file utility functions.

1247 the SKE interface a bit.
1249 * Fixed padding problem in PKCS#1. The padding was not actually
1250 random since the random number generator was used incorrectly.
1251 This security bug affects only when encrypting with PKCS#1, and
1252 it is not currently used at all in SILC. SILC only use signing
1253 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.

1316 Affected files irssi/src/silc/core/silc-core.c,
1317 irssi/src/fe-text/silc.c.
1319 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1321 * Added new configuration options and blocks:
1322 keepalive_secs, reconnect_count, reconnect_interval,
1323 reconnect_interval_max, reconnect_keep_trying and
1324 require_reverser_lookup. Added ConnectionParam block, and
1325 implemented the connection parameters when connecting as
1326 initiator and when accepting connections as responder.

1338 the connection configuration object from the SilcServerConnection
1339 object instead of finding it during the connecting phase.
1340 Added the configuration object to SilcServerConnection struct.
1341 Affected files silcd/server_internal.h, server.c.
1343 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1345 * Add the client on channel after it was resolved at the
1346 channel message receiving, and it was not already on the
1347 channel. Affected file lib/silcclient/client_channel.c.
1349 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1365 authentication to be set at the same time.
1367 Added `prefer_passphrase_auth' setting in config file which
1368 can be used to set to prefer passwd auth if both passwd and
1369 public key is set. If not set, public key is preferred.
1370 This has effect only when being initiator (responder will try
1373 Added support for authentication with passphrase and public key
1374 at the same time. The passphrase is tried first always since
1375 it is faster to check.
1377 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
1379 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

1425 * Fixed the file transfer's key agreement payload to include
1426 zero port also if the hostname is NULL because it could not
1429 Call file transfer monitor callback now also if error occurs
1430 during key agreement protocol.
1432 Changed the silc_client_file_send interface to return the
1433 SilcClientFileError instead of session id. The session ID
1434 is returned into pointer provided as argument.

1451 file lib/silcutil/silclog.c.
1453 * Fixed the channel message payload decryption in the function
1454 silc_channel_message_payload_decrypt to not modify the original
1455 buffer before it is verified that the message decrypted
1456 correctly. Otherwise, next time it is called with correct
1457 channel key it won't encrypt since the payload is corrupted.
1458 Affected file lib/silccore/silcchannel.c.
1460 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1472 * Fixed a bug in hash table internal routine for traversing
1473 the table with foreach callback. The current entry may
1474 become invalid in the callback but it was referenced after
1475 the callback returned.
1477 Do not allow auto rehashing of hash table during the
1478 silc_hash_table_foreach operation, for same reasons as it is
1479 not allowed for SilcHashTableList. Affected files are
1480 lib/silcutil/silchashtable.[ch].
1482 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>

1503 users list to SilcHashTable. The affected files are
1504 lib/silcclient/idlist.[ch].
1506 * Fixed a bug in hash table tarversing. While the hash table
1507 is traversed with SilcHashTableList the table must not be
1508 rehashed. It is now guaranteed that auto rehashable tables
1509 are not rehashed while tarversing the list. Also defined that
1510 silc_hash_table_rehash must not be called while tarversing
1511 the table. Added function silc_hash_table_list_reset that must
1512 be called after the tarversing is over. The affected files are
1513 lib/silcutil/silchashtable.[ch].
1515 * Changed all hash table traversing to call the new
1516 silc_hash_table_list_reset in server and in client library.
1518 * Added function silc_client_on_channel to return the
1519 SilcChannelUser entry if the specified client entry is joined
1520 on the specified channel. This is exported to application as
1521 well. Affected files lib/silcclient/client_channel.c, silcapi.h.

1526 server. The notify for mode change must be sent always and
1527 not only if !cmd->pending. Affected file silcd/command.c.
1529 * Fixed the WHOWAS command's reply sending to support the
1530 lists correctly. Affected file silcd/command.c.
1532 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1534 * When sending JOIN command to router for processing the
1535 sender's old command identifier was not saved back to the
1536 sender's command context, fixed now. The affected file is
1539 * Create the key in JOIN command of the router did not return
1540 the channel key, added check for this. Affected file is
1543 * Fixed a channel ID update bug in JOIN command reply. Do
1544 not directly upgrade the ID but call the function
1545 silc_idlist_replace_channel_id if the ID was changed.
1546 Affected file silcd/command_reply.c.
1548 * Fixed memory leaks from command calling if it would fail.
1549 Affected file silcd/command.c.
1551 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1553 * Applied patches from cras:
1555 Memory leak fixes around libaries, irssi window resize fix,
1556 new silclist.h and silcdlist.h, all extern inline changed to
1559 * Removed dotconf from lib/dotconf, not needed anymore.
1561 * Removed TRQ from lib/trq, not needed anymore.
1563 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
1564 with server connections. Later this will be configurable
1565 in config file after new config file is done. Affected file
1568 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1570 * Fixed a crash in server related to channel announcements.
1571 Affected file silcd/server.c.
1573 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1575 * Fixed memory leaks in silc_server_create_new_channel*
1576 functions. Affected file silcd/server.c.
1578 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
1579 which ID was changed. This way the router will send the
1580 user list for the channel again, and server won't be in
1581 desync in some rare circumstances. Affected file is
1582 silcd/packet_receive.c.
1584 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1586 * Check for NULL socket pointer in the function
1587 silc_server_packet_send_to_channel_real. Affected file
1588 silcd/packet_send.c.
1590 * Fixed the BAN notify handling to correctly remove ban
1591 list. Affected file silcd/packet_receive.c.
1593 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1595 * Fixed some header addition to Toolkit distribution in
1596 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
1598 * Added lib/silcclient/client_ops_example.h as an template
1599 file for application programmers to quickly start using
1600 the SilcClientOperation functions in their application.
1601 Updated the lib/silcclient/README as well to tell about this
1602 nice file made available.
1604 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1606 * Call silc_server_remove_from_channels when removing client
1607 entry when NO_SUCH_CLIENT_ID was received. Affected file
1608 is silcd/command_reply.c.
1610 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1612 * Added server & router operator statistics updating. Affected
1613 file silcd/packet_receive.c and silcd/command.c.
1615 * Fixed the SERVER_SIGNOFF notify handling on normal server
1616 not to save the history information for clients. Same was
1617 fixed earlier in remove_clients_by_server function, but not
1618 here. Affected file silcd/packet_receive.c.
1620 * Raised the default connection-retry count from 4 to 7 in
1621 server. Affected file silcd/server.h.
1623 * Cancel any possible reconnect timeouts when we start the
1624 key exchange. Affected file silcd/server.c.
1626 * Do not reconnect on connection failure when SCONNECT was
1627 given. Affected files silcd/server.[ch].
1629 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1631 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
1633 * Fixed the NICK command to always give the unformatted
1634 nickname to the one giving the NICK command. If unformatted
1635 nickname is cached already it will be formatted and the
1636 local entry will always get the unformatted nickname.
1637 Affected file lib/silcclient/idlist.c.
1639 * Fixed some double frees from client library commands.
1640 Affected file is lib/silcclient/command.c.
1642 * Fixed CUMODE command in server to assure that no one can
1643 change founder's mode than the founder itself, there was a
1644 little bug. Affected file silcd/command.c.
1646 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1648 * Removed the SilcClientCommandDestructor from the client
1649 libary, it is not needed anymore. Affected files are
1650 lib/silcclient/silcapi.h, command[_reply].[ch],
1651 client_notify, idlist.c.
1653 * Fixed GETKEY command to first resolve client, and then
1654 resolve the server only if the client was not found, instead
1655 of resolving both at the same time. Affected file is
1656 lib/silcclient/command.c.
1658 * Added silc_client_start_key_exchange_cb and lookup the
1659 remote hostname and IP address before starting the key
1660 exchange with server. The affected file is
1661 lib/silcclient/client.c.
1663 * The server's public key is now saved using the IP address
1664 of the server and not the servername for the filename.
1665 The hostname public key filename is checked as an fall back
1666 method if the IP address based filename is not found.
1668 Fixed the GETKEY command to save the fetched server key
1669 in correct filename.
1671 Print the remote server's hostname now when new key is
1672 received during connection process. Affected file is
1673 irssi/src/silc/core/client_ops.c.
1675 * Return always our own public key to the client if it asks
1676 for it with GETKEY command. Affected file silcd/command.c.
1678 * Removed the use_auto_addr variable from default config
1679 file since it was in wrong section. Affected file is
1682 * Fixed TOPIC_CHANGE notification to not route it when it
1683 was sent using silc_server_send_notify_to_channel function.
1684 Affected file silcd/command.c.
1686 * Fixed silc_server_send_notify_kicked to send the kicker's
1687 Client ID also, it was missing. Affected files are
1688 silcd/command.c, silcd/packet_send.[ch].
1690 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1692 * Do not save client history information in SERVER_SIGNOFF.
1693 Fixes the bug in normal server that it does not detect
1694 the client becoming valid after the server becomes back
1695 online. Affected file silcd/server_util.c.
1697 * Added `sock_error' field into the SilcSocketConnection
1698 context. When error occurs during socket operation (read
1699 or write) the error is saved. Added also new function
1700 silc_socket_get_error to return human readable socket error
1701 message. Affected files are lib/silcutil/silcsockconn.[ch],
1702 lib/silcutil/unix/silcunixsockconn.c, and
1703 lib/silcutil/win32/silcwin32sockconn.c.
1705 * The server now prints the socket error message in the
1706 signoff for client. Affected file silcd/server.c.
1708 * Fixed the `created' channel information sending from router
1709 to server in JOIN command. Checks now whether the channel
1710 really was created or not and set it according that.
1712 Fixed the JOIN command to use the client entry's current
1713 ID during the joining procedure instead of the one it sent
1714 in the command (it is checked though), since it can change
1715 between the packet processing and command processing, and
1716 would just case unnecessary pain in the client end. Affected
1717 file silcd/command.c.
1719 * Fixed a channel key payload sending to use correct channel
1720 ID when the server was forced to change the channel's ID by
1721 router. Router sent the key payload with the old Channel ID.
1722 Affected file silcd/packet_receive.c.
1724 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1726 * Call silc_server_save_channel_key only if the key payload
1727 was provided in the JOIN command's command reply. Affected
1728 file silcd/command_reply.c.
1730 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1732 * Fixed silc_mp_sizeinbase to return the value correctly with
1733 MPI. Affected file lib/silcmath/mp_mpi.c.
1735 * Fixed the stop_server signal to correctly stop the scheduler
1736 and gracefully stop the server when SIGTERM or SIGINT signals
1737 are received. Affected file silcd/silcd.c.
1739 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1741 * Simple handling of TERM and HUP signals. Also added some log
1742 flushing call around. Affected file is
1745 * Fixed small bugs in silclog.c. Now buffering output will take
1746 effect after 10 seconds since startup: This will ensure that
1747 no important startup messages are lost. Also output redirection
1748 will preserve original format ([Date] [Type] message).
1749 Affected file is lib/silcutil/silclog.c.
1751 * Added two options to the config file, in the logging section:
1752 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1753 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1755 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1757 * Do not print the warning about log files not being initialized
1758 more than once to avoid excess logging. Affected file is
1759 lib/silcutil/silclog.c.
1761 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1762 the SIM copying in make install in Makefile.am.pre.
1764 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1766 * Rewritten silclog APIs. Globally interesting changes follows:
1767 silc_log_set_files() changed to silc_log_set_file().
1768 silc_log_set_callbacks() changed to silc_log_set_callback().
1769 ROBOdoc documented silclog header file.
1770 SilcLogCb now returns bool to wether inihibit the default
1771 handler or not (to keep the old behaviour return always TRUE).
1772 The new APIs should also fix the problem of the
1773 silcd_error.log file that was written in the current directory.
1776 Log files streams will remain opened after silc_log_set_file()
1777 call, means less CPU usage notably on high traffic servers.
1778 File streams are now full buffered, and flushed to the disk
1779 every 5 minutes, lesses HD activity and CPU usage.
1780 Messages can be redirected, allowing admins to configure
1781 one single logfile for all server messages.
1782 the silc_log_quick global variable to activate fast-logging.
1783 Affected files lib/silcutil/silclog.[ch]
1785 * Changed some code to conform new silclog APIs. Affected
1786 files are doc/example_silcd.conf.in, silcd/server.c
1787 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1790 * Fixed a memory leak that could occur in some situations.
1791 Affected file silcd/serverconfig.c.
1793 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1795 * Added the silc_client_del_client to remove the client from
1796 all channels as well. Affected file lib/silcclient/idlist.c.
1798 * Fixed the client library to correctly remove the client
1799 from all channels when the client entry is being destroyed.
1800 Affected file lib/silcclient/client_notify.c, command.c.
1802 * Added auto-nicking support to the client library. If the
1803 applicatio now sets client->nickname it will be sent to the
1804 server after connecting by the library. This way for example
1805 SILCNICK (or IRCNICK) environment variables will have effect
1806 and always change the nickname automatically to whatever
1807 it is wanted. Affected file lib/silcclient/client.[ch].
1809 * Renamed silc_server_command_bad_chars to the
1810 silc_server_name_bad_chars and moved it to the
1811 silcd/server_util.[ch]. Added also new function
1812 silc_server_name_modify_bad to return nickname that
1813 includes bad characters as new nickname without those
1814 bad characters. This check and modify is now used in
1815 silc_server_new_client when the username is initially set
1816 as nickname, so it must be checked to be valid nickname.
1817 Affected file silcd/packet_receive.c.
1819 * The nickname length is now taken from the packet for real
1820 and not trusted to strlen() since it clearly can return
1821 wrong length for nickname including bad characters. This
1822 also applies to channel names. Affected file silcd/command.c.
1824 * Removed the lib/silcsilm/modules directory. Modules are now
1825 compiled into the lib/silcsim. Fixed the copying of the
1826 modules to follow symbolic links in Makefile.am.pre.
1828 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1830 * Fixed silc_string_regexify list creation. Fixes bugs with
1831 BAN and INVITE commands in server. The affected file is
1832 lib/silcutil/unix/silcunixutil.c.
1834 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1836 * Removed the command destructor entirely from the server's
1837 command and command reply routines. It is not needed, and
1838 its usage was buggy and caused crashes. Affected files are
1839 silcd/command[_reply].[ch].
1841 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1843 * Cancel protocol and NULL sock->protocol if timeout
1844 occurred during protocol. Affected file silcd/server.c.
1846 * Cancel protocol timeouts always before calling the final
1847 callback, to assure that after final callback is called
1848 no other state will be called for the protocol anymore.
1849 Affected file silcd/protocol.c.
1851 * Print error log if incoming connection configuration could
1852 not be found. Affected file silcd/server.c.
1854 * Fixed JOIN command to correctly save the founder mode
1855 to the client on normal SILC server, when the channel
1856 was created by the router. Affected file silcd/command.c.
1858 * Fixed LIST command (hopefully) to send correct reply
1859 packets. Affected file silcd/command.c.
1861 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1863 * The silc_packet_receive_process now returns FALSE if the
1864 read data was invalid packet, and TRUE if it was ok.
1866 The server now checks that if unauthenticated connection
1867 sends data and its processing fails the server will close
1868 the connection since it could be a malicious flooder.
1870 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1872 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1874 * Make sure the warning about error opening a log file is
1875 printed only once and not everytime it fails (produces
1876 too much useless log). Affected file lib/silcutil/silclog.c.
1878 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1880 * Made the silc_server_daemonise() function more readable.
1881 Affected file silcd/server.c.
1883 * Pid file is now optional, the user may comment it out from
1884 the config file. Removed define SILC_SERVER_PID_FILE, we
1885 don't need a default any longer. Affected file
1886 configure.in.pre, lib/Makefile.am.pre.
1888 * Make some use of the pid file. The server now dies at startup
1889 if it detects a valid pid file on his path. The server would
1890 die anyway in this circumstance, because of the bind() failure.
1891 Affected file silcd/silcd.c.
1893 * No longer compiling lib/dotconf.
1895 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1897 * Fixed JOIN command parsing not to crash. Affected file
1898 lib/silcclient/command.c.
1900 * Fied the NICK_CHANGE notify to add the new client entry
1901 even it is resolved. This removes an <[unknown]> nick
1902 thingy bug in the client. Affected file is
1903 lib/silcclient/client_notify.c.
1905 * Do not try to allocate 0 bytes (efence does not like it)
1906 in lib/silccore/silccomand.c when encoding payload.
1908 * Do not take IRCNICK as nickname in Irssi SILC client since
1909 it is not possible to set nickname before hand connecting
1910 the server (TODO has an entry about adding auto-nicking
1913 * Changed the silc_server_command_pending to check whether
1914 there already exists an pending entry with the specified
1915 command, command identifier and pending callback. This is
1916 to fix IDENTIFY and WHOIS related crashes that may register
1917 multiple pending commands with same identifier. Affected
1918 file silcd/command.c.
1920 * Fixed the server to reconnect to the router even if it
1921 was already reconnecting and EOF was received. This to
1922 fix a possibility that the server wouldn't ever try to
1923 auto-reconnect to the router. Affected file silcd/server.c.
1925 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1927 * Fixed the server's password authentication to use the
1928 length of the locally saved password, and not the one
1929 sent in the packet. Affected file silcd/protocol.c.
1931 * Fixed same password authentication problem in the
1932 Authentication Payload handling routines in
1933 lib/silccore/silcauth.c.
1935 * Yet another password authentication problem fixed with
1936 channel password handling in silcd/command.c.
1938 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1940 * If first character of string in silc_parse_userfqdn is '@'
1941 then do not parse it. Affected file is
1942 lib/silcutil/silcutil.c.
1944 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1946 * Fixed minor bug in IDENTIFY command reply sending, which
1947 caused various weird problems during JOIN when it was
1948 resolving names for users. Affected file silcd/command.c.
1950 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1952 * Fixed the IDENTIFY command reply sending to chech better valid
1953 clients. It was possible to send incomplete list of replies.
1954 Affected file silcd/command.c.
1956 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1958 * Added silc_client_command[s]_[un]register functions now to
1959 dynamically register the commands in client library. Removed
1960 the static table of commands. This allows the client library
1961 to call commands without causing the application to know about
1962 what commands library has called.
1964 Removed the INFO command reply kludge to detect when the command
1965 was called by library. Now library use its own command reply
1966 function for INFO command.
1968 Added function silc_client_command_call to call a command.
1969 Application can use it to call command, not access the structure
1972 Now all commands that are sent by the client library (not
1973 explicitly sent by application) use own command reply functions.
1975 Affected files around lib/silcclient/ and in
1976 irssi/src/silc/core/.
1978 * Fixed the WHOIS command reply sending to chech better valid
1979 clients. It was possible to send incomplete list of replies.
1981 Fixed the WHOIS and IDENTIFY to send the request to router
1982 if normal server did not do it and did not find any results.
1984 Affected file silcd/command.c.
1986 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1988 * Moved the internal data from SilcClient context into its
1989 own file, not accesible to application. Affected files
1990 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1991 and other files in client library.
1993 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1995 * Added doc/examples installation target in Makefile.am.pre.
1998 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2000 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
2001 commands the found client entry will be removed from the
2002 cache, after notifying application about the error. Affected
2003 file lib/silcclient/command_reply.c.
2005 * Changed the /MSG to check for exact nickname user gave, and
2006 not let `nick' match `nick@host' if it is only one found. Now,
2007 user must type the exact nickname (like nick@host2) even if
2008 there are no more than one same nicks found. This is to avoid
2009 a possibility of sending nickname to wrong nickname since
2010 `nick' could match `nick@host'. Affected file is
2011 irssi/src/core/silc-servers.c.
2013 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2015 * Do not print "you are now server operator" or similar when
2016 giving /away command. Affected files are
2017 irssi/src/silc/core/client_ops.c, silc-servers.h.
2019 * Made the silc_server_command_pending_error_check to send
2020 the same command reply payload it received back to the
2021 original sender of the command. This way all arguments
2022 that was received by the server will be received by the
2023 client too. Affected file silcd/command.c.
2025 * Added the silc_idcache_add to return the created cache entry
2026 to a pointer. Affected file lib/silccore/silcidcache.[ch].
2028 * Add global clients to expire if they are not on any channel.
2029 This is because normal server will never know if they signoff
2030 if they are not on any channel. The cache expiry will take
2031 case of these entries. This is done by normal servers only.
2032 The affected files are silcd/command_reply.c,
2033 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
2035 * If server receives invalid ID notification for WHOIS or
2036 IDENTIFY and the ID exists in the lists, it is removed.
2037 Affected file silcd/command_reply.c.
2039 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
2040 in client then client entry that it matches is searched and
2041 the nickname is printed on the screen for user. Affected
2042 file irssi/src/silc/core/client_ops.c.
2044 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2046 * Use cache entry expire time in the LIST command reply to
2047 purge old entries from the cache after the LIST command
2048 reply has been received. This way we don't have non-existent
2049 entries in the cache for too long. Affected file is
2050 silcd/command_reply.c.
2052 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2054 * If we are normal server, and we've not resolved client info
2055 in WHOIS or IDENTIFY from router, and it is global client,
2056 we'll check whether it is on some channel. If it is not
2057 then we cannot be sure about its validity and will resolve it
2058 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
2059 file silcd/command.c.
2061 * Search channel by name (if possible) rather than by ID
2062 in IDENTIFY command's command reply. Affected file is
2063 silcd/command_reply.c.
2065 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2067 * Distribute to the channel passphrase in CMODE_CHANGE notify.
2068 Updated specs and implemented it. Affected file silcd/command.c,
2069 silcd/packet_send.c and silcd/packet_receive.c.
2071 * Implemented the <founder auth> payload handling in the JOIN
2072 command. If provided all conditions for channel joining
2073 except requirement to provide correct passphrase can be
2074 overrided by the channel founder. Updated the protocol specs.
2075 Affected file silcd/command.c.
2077 Added support for founder auth in JOIN command in client
2078 library. Fixed the parsing of the JOIN command now to support
2079 all options as they should be. The affected file is
2080 lib/silcclient/command.c.
2082 * Optimized the WHOIS and IDENTIFY commands to send the request
2083 to router only if it includes nicknames or other names. If
2084 they include only IDs then check the local cache first before
2085 routing. Affected file is silcd/command.c.
2087 * Added channels topic announcements. Affected file is
2088 silcd/packet_receive.c and silcd/server.c.
2090 * Fixed the silc_server_send_notify_topic_set to really destine
2091 the packet to channel. Affected file silcd/packet_send.c.
2093 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
2094 library. Affected file lib/silcclient/client_notify.c.

2113 * ROBOdoc documented the lib/silcske/groups.h file and a
2114 bit changed the interface for better.
2116 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2118 * Update the client entry context in the ID cache after
2119 nick change. Affected file lib/silcclient/command.c.
2120 Fixes the CUMODE command when regaining founder privileges,
2121 and a little WHOIS problem.
2123 * Fixed silc_net_gethostbyname to correctly call the
2124 inet_ntop. Affected file lib/silcutil/silcnet.c.
2126 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2128 * Added IPv6 support checking to the configure.in.pre, added
2129 also --enable-ipv6 option to override the check. Affected
2130 file configure.in.pre.
2132 * The silc_thread_create now calls the start function
2133 directly if threads support is not compiled in. Removes
2134 ugly #ifdef's from generic code. Affected files are
2135 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
2137 * Added silc_net_gethostby[name/addr]_async to asynchronously

2149 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
2150 routines. Added silc_net_is_ip[4/6]. Affected file is
2151 lib/silcutil/unix/silcunixnet.c. All routines that take
2152 address as argument now supports both IPv4 and IPv6 addresses.
2154 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2156 * Fixed LIST command reply sending in server. Affected file
2159 * Server now sends the kicker's client ID in the KICK notify
2160 to the kicked client. Affected file silcd/command.c.
2162 * The client library now parses the kickers client ID and
2163 UI displays it. Affected files lib/silcclient/client_notify.c
2164 and irssi/src/silc/core/silc-channels.c, module-formats.c.
2166 * Made all payload parsing function prototypes consistent.
2167 They all take now const unsigned char * and uint32 pair as
2168 the payload data instead of SilcBuffer. Changes all around
2169 the source tree. Other unsigned char* -> const unsigned char*
2170 changes around the tree as well.
2172 * Optimized SFTP client and server packet sending not to
2173 allocate new buffer for each packet but to recycle the
2174 first allocated buffer. Affected files are
2175 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
2177 * Optimized the SFTP client to use SilcList instead of
2178 SilcDList for requests, because it is faster. Affected file
2179 is lib/silcsftp/sftp_client.c.
2181 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
2182 into lib/silccore/silcid.[ch].
2184 Renamed silcpayload.[ch] into silcargument.[ch].
2186 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2188 * If client entry is deleted with active key agreement
2189 session, abort the session.
2191 The silc_client_abort_key_agreement now calls the completion
2192 callback with new SILC_KEY_AGREEMENT_ABORTED status.
2194 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
2197 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2199 * Don't use __restrict in older GCC's. Affected file is
2200 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
2202 * silc_net_localhost now attempts to reverse lookup the
2203 IP/hostname. Affected file lib/silcutil/silcnet.c.
2205 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
2206 command. It can be used to gain founder privileges at
2207 the same time when joining the channel.
2209 Defined that the SILC_NOTIFY_TYPE_KICKED send the
2210 kicker's client ID as well. Updated protocol specs.
2212 Defined that the server must send SILC_COMMAND_IDENTIFY
2213 command reply with error status to client who sent
2214 private message with invalid client ID.
2216 Updated the protocol specification.
2218 * Added silc_server_send_command_reply to send any
2219 command reply. Affected file silcd/packet_send.[ch].
2221 * Added silc_id_payload_encode_data to encode ID payload
2222 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
2224 * The server now send IDENTIFY command reply with error
2225 status if client ID in private message is invalid. Affected
2226 file silcd/packet_receive.c.
2228 * Save the server key file with server's IP address in
2229 the filename instead of hostname. The affected file is
2230 irssi/src/silc/core/client_ops.c.
2232 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2234 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
2237 * Added libtool support for compiling shared objects in
2238 lib/silcsim. Affected file configure.in.pre and
2239 lib/silcsim/Makefile.am. Original patch by cras.
2241 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2243 * Pid file configuration, and server's config file fixes
2244 patch by toma. Updated CREDITS file.
2246 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2248 * Fixed silc_client_channel_message to not try to decrypt
2249 the message twice if it resolved the destination client
2250 information. This could cause of dropping one channel
2251 message. Affected file lib/silcclient/client_channel.c.
2253 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2255 * Added silc_client_run_one into lib/silcclient/silcapi.h and
2256 lib/silcclient/client.c. This function is used when the SILC
2257 Client is run under some other scheduler, or event loop or
2258 main loop. On GUI applications, for example this may be
2259 desired to used to run the client under the GUI application's
2260 main loop. Typically the GUI application would register an
2261 idle task that calls this function multiple times in a second
2262 to quickly process the SILC specific data.
2264 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2266 * Fixed silc_server_drop() for dropping the supplementary
2267 groups as well, this could cause a security hole on some
2270 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2272 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
2275 * Write PID file after dropping privileges. Added -F option
2276 to run server on foreground. A patch by debolaz.
2277 Affected files silcd/server.c, silcd/silcd.c.
2279 * Fixed MOTD to return the MOTD file server name. Affected
2280 file silcd/command.c.
2282 * Added INFO command reply handling to the Irssi SILC Client.
2283 Affected file irssi/src/silc/core/client_ops.c.
2285 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2287 * Fixed the silc_idcache_list_* routines to really support
2288 the dynamic list. Fixes a crash. Affected file is
2289 lib/silccore/silcidcache.c.
2291 * Fixed the LIST command reply to really call LIST command's
2292 pending callbacks. Affected file silcd/command_reply.c.
2294 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2296 * Update conn->local_entry->nickname after giving NICK
2297 command. Affected file lib/silcclient/command.c.
2299 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
2301 * Added the [pid] option to the silcd configuration file
2303 Affected files: serverconfig.[ch] and silcd.c
2305 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2307 * Save fingerprint in WHOIS command reply in server.
2308 Affected file silcd/command_reply.c.
2310 * Fixed NICK commands pending callback registration.
2311 Affected file lib/silcclient/command.c.
2313 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2315 * Use ++server->cmd_ident when sending commands in server,
2316 instead of random number. Affected file silcd/command.c.
2318 * Fixed GETKEY command reply to call actually GETKEY pending
2319 command callbacks. Affected file silcd/command_reply.c.
2321 * A bit stricter check for nicknames. Check for same nickname
2322 in NICK command also. Affected file silcd/command.c.
2324 * Do not call INFO command everytime client ID changes, only
2325 during first connecting. Affected file lib/silcclient/client.c.
2327 * Set the new nickname only after successful command reply for
2328 NICK command is returned by server. Affected file
2329 lib/silcclient/command.c.
2331 * Remove nicknames from nicklist during server_signoff notify.
2332 Should fix /NAMES bit more. The affected file is
2333 irssi/src/silc/core/silc-channels.c.
2335 * Added `fingerprint' field to the SilcIDListData in the
2336 silcd/idlist.h to hold the fingerprint of the client's
2339 Send the fingerprint of the client's public key in WHOIS
2342 Affected files silcd/command.c, and silcd/idlist.[ch].
2344 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
2345 create fingerprint from given data.
2347 * Show the fingerprint of the client's public key in WHOIS.
2348 Affected files irssi/src/module-formats.[ch] and
2349 irssi/src/silc/core/client_ops.c.
2351 * Format the multiple same nicknames also during JOIN and
2352 NICK_CHANGE notifys. Affected file is
2353 lib/silcclient/client_notify.c.
2355 * Do not print error on screen for invalid private message
2356 payload since it can come if someone is sending private
2357 messages with wrong key. Affected file
2358 lib/silccore/silcprivate.c.
2360 * Fixed multiple concurrent /PING crash. Affected file
2361 lib/silcclient/command.c.
2363 * Changed the wrong ID encoding. All IP addresses must be
2364 in MSB first order in encoded format. They were encoded
2365 wrong and was in LSB format. Affected files are
2366 silcd/serverid.c, lib/silcutil/silcutil.c.
2368 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
2370 * Call the `connect' client operation through the scheduler
2371 in case of error. Affected file lib/silcclient/client.c.
2373 * Call the `failure' client operation even if the error
2374 occurred locally during a protocol. Affected file is
2375 lib/silcclient/protocol.c.
2377 * Added support of sending LIST command to router from normal
2378 server. This way normal server can get list of all channels
2379 in the network too. Fixed the channel list sending in the
2380 server too. Affected files are silcd/command.c, and
2381 silcd/command_reply.[ch].
2383 * Added silc_server_update_channels_by_server and
2384 silc_server_remove_channels_by_server. They are used during
2385 disconnection of primary router and in backup router protocol.
2386 Affected file silcd/server_util.[ch], silcd/server.c and
2387 silcd/server_backup.c.
2389 * Fixed channel adding to global list in IDENTIFY command
2390 reply in server. Affected file silcd/command_reply.c.
2392 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2394 * If the incoming packet type is REKEY or REKEY_DONE process
2395 that packet always synchronously. Fixes yet another MAC
2396 failed error on slow (dialup) connections. Affected file
2397 lib/silcclient/client.c and silcd/server.c.
2399 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2401 * Call check_version SKE callback for initiator too. Affected
2402 file lib/silcske/silcske.c.
2404 * Implemented fix for security hole found in the SKE that was
2405 fixed in the specification few days back; the initiator's
2406 public key is now added to the HASH value computation.
2407 Added backwards support for the old way of doing it too, for
2408 old clients and old servers. Affected file is
2409 lib/silcske/silcske.c.
2411 * Enabled mutual authentication by default in SKE. If initiator
2412 is not providing mutual authentication the responder will
2413 force it. This will provide the proof of posession of the
2414 private key for responder. The affected files are
2415 lib/silcclient/protocol.c and silcd/protocol.c.
2417 * Do not cache anymore the server's public key during SKE.
2418 We do mutual authentication so the proof of posession of
2419 private key is done, and if the server is authenticated in
2420 conn auth protocol with public key we must have the public
2421 key already. Affected file silcd/protocol.c.
2423 * Added new global debug variable: silc_debug_hexdump. If
2424 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
2425 file lib/silcutil/silclog.[ch].
2427 * Fixed compilation warning due to char * -> const char *.
2428 Affected files lib/silcutil/silcnet.h, and
2429 lib/silccore/silcauth.[ch].
2431 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2433 * Fixed CMODE command when new channel key was created. If
2434 the creation failed the old key was removed. Next time giving
2435 same command would crash the server since the old key was
2436 freed already. Affected file silcd/command.c.
2438 * Fixed the silc_server_announce_get_channels to not crash
2439 on reconnect. Affected file silcd/server.c.
2441 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2443 * Added silc_log_set_debug_string function to set a regex
2444 string to match for debug output. Only the function names,
2445 or filenames matching the given debug string is actually
2446 printed. This way it is possible to filter out those debug
2447 strings that user is not interested in.
2449 Fixed a bug in silc_string_regexify.
2451 Affected files lib/silcutil/silclog.[ch], and
2452 lib/silcutil/unix/silcunixutil.c.
2454 * Changed the -d options in both server and Irssi SILC client
2455 to take the debug string as argument. Affected files
2456 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
2458 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2460 * Added silc_hash_babbleprint to create a Bubble Babble
2461 Encoded fingerprint. The encoding is developed by Antti
2462 Huima (draft-huima-babble-01.txt), and it creates human
2463 readable strings out of binary data. Affected file
2464 lib/silccrypt/silchash.[ch].
2466 * Print the babble print now in addition of fingerprint as well
2467 in Irssi SILC client. Affected files are
2468 irssi/src/fe-common/silc/module-formats.[ch],
2469 irssi/src/fe-common/silc/core/client_ops.c.
2471 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2473 * Fixed a security problem found in SKE. The initiator's
2474 public key too is now added to the HASH hash value creation
2475 which is signed by the responder to create the SIGN value.
2476 This will prevent anyone in the middle to lie to the responder
2477 about the initiator's public key. If this is done now, the
2478 man in the middle will get caught. Updated the protocol
2481 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2483 * Better installation directory handling. Configure module
2484 paths and other paths automatically to example_silc* files
2485 in doc/. A patch by toma.
2487 * Fixed compiler warning from MPI library, and from SILC RNG.
2490 * Added SILC_SERVER_PID_FILE to define the pid file for server.
2491 It can be configured with ./configure. A patch by toma.
2493 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2495 * Find correct make to use in prepare-clean. A patch by
2496 toma. Affected file prepare-clean.
2498 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
2500 * Added irssi variables use_auto_addr, auto_bind_ip,
2501 auto_bind_port and auto_public_ip.
2503 * Changed the interface for silc_client_send_key_agreement
2504 in lib/silcclient/silcapi.h
2508 irssi/src/silc/core/silc-core.c
2510 lib/silcclient/silcapi.h
2511 irssi/src/silc/core/silc-channels.c
2512 lib/silcclient/client_keyagr.c
2515 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2517 * Added silc_pkcs_public_key_compare to compare two
2518 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
2520 * Check that the client who set the founder mode on the
2521 channel is the same client that is giving the founder
2522 mode to itself. It is done by comparing the saved public
2523 key (it is saved even in the authentication is passphrase).
2524 Affected file silcd/command.c.
2526 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2528 * Do not process packet for disconnected socket connection.
2529 Affected file lib/silccore/silcpacket.c.
2531 * Process the DISCONNECT packet through scheduler in the
2532 client library. Affected file lib/silcclient/client.c.
2534 * Fixed the silc_client_packet_parse to not to increase
2535 the packet sequence number if the conn->sock and the
2536 current socket connection is not same. This can happen
2537 for example during key agreement when the conn includes
2538 multiple socket connections (listeners). Affected file
2539 lib/silcclient/client.c.
2541 * The sender of the file transfer request now provides also
2542 the pointer (listener) for the key exchange protocol. If
2543 the listener cannot be created then it sends empty key
2544 agreement and lets the receiver provide the listener.
2546 Added `local_ip' and `local_port' arguments to the
2547 silc_client_file_send. If they are provided they are used,
2548 if not then it will attempt to find local IP address, if
2549 not found or bind fails then the remote client will provide
2552 Affected files are lib/silcclient/client_ftp.c and
2553 lib/silcclient/silcapi.h.
2555 * Extended the FILE SEND command to support defining the
2556 local IP and port for key exchange listener. They are
2557 optional. Affected file irssi/src/silc/core/silc-servers.c.
2559 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2561 * Defined to WHOIS command reply the sending of fingerprint
2562 of the client's public key (if the proof of posession of the
2563 corresponding private key is verified by the server).
2564 Updated to the protocol specification.
2566 * Added support of receiving the client's public key's
2567 fingerprint in command reply in client library. Affected
2568 file is lib/silcclient/command_reply.c, and
2569 lib/silcclient/idlist.[ch].
2571 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2573 * Do not send over 128 chars long nickname to the server
2574 in NICK command. Affected file lib/silcclient/command.c.
2576 * Do not send over 256 chars long channel names to the server
2577 in JOIN command. Affected file lib/silcclient/command.c.
2579 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2581 * Assure that silc_server_close_connection cannot be called
2582 twice for same socket context. Affected file is
2585 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2587 * Send error message to application if opening file for
2588 writing during file transfer fails. Affected file is
2589 lib/silcclient/client_ftp.c.
2591 Remove all file transfer sessions for a client that we're
2592 removing from ID cache.
2594 Affected file is lib/silcclient/client_ftp.c.
2596 * Fixed silc_net_addr2bin to return correct address. Affected
2597 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2599 * Fixed file transfer session removing on signoff notify.
2600 Affected file irssi/src/silc/core/silc-servers.c.
2602 * Added the SilcClientFileError to be returned in the monitor
2603 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
2604 Affected file lib/silcclient/silcapi.h.
2606 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2608 * Fixed a crash in silc_client_ftp_free_sessions and
2609 silc_client_ftp_session_free_client. Affected file
2610 lib/silcclient/client_ftp.c.
2612 * Added `disabled' field in the SilcChannelEntry in the server
2613 to indicate if the server entry is disabled. Affected file
2614 silcd/idlist.h, silcd/command[_reply].c.

2624 client library. Affected file lib/silcclient/client_prvmsg.c.
2626 * Do not actually remove the client directly from ID cache
2627 during SERVER_SIGNOFF, but invalidate it. This way we
2628 preserve the WHOWAS info for the client. Affected file
2629 silcd/server_util.c.
2631 * Fixed SERVER_SIGNOFF notify handling in the server. The
2632 server is now able to process incoming SERVER_SIGNOFF notify
2633 for a server that it doesn't even know about. It will remove
2634 the clients provided in the notify. Affected file
2635 silcd/packet_receive.c.
2637 * Check for partial packet in data queue after every packet that
2638 was found from the queue. Return and wait for more data if
2639 there is partial data in queue. Affected file is
2640 lib/silccore/silcpacket.c.
2642 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>

2650 * Check that newsize in silc_buffer_realloc is larger than
2651 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
2653 * Added better monitor of file transfers. It now monitors
2654 key agreement protocol during the file transfer too. Added
2655 error reporting too. Affected files
2656 irssi/src/silc/core/silc-servers.c,
2657 irssi/src/fe-common/silc/module-formats.[ch].
2659 * Wrote a help file for FILE command.
2661 * Added silc_rng_global_get_byte_fast to get not-so-secure
2662 random data as fast as possible. Random data is read from
2663 /dev/urandom if available and from the SILC RNG if not
2664 available. It is used in padding generation. Affected file
2665 lib/silccrypt/silcrng.[ch].
2667 * All packets in client library are now processed synchronously.
2668 Optimized packet processing a lot. Affected file
2669 lib/silcclient/client.c.
2671 * All server connection packets are processing synchronously
2672 now in server, to optimize packet processing. Affected file
2675 * Include files are installed now only in Toolkit distribution
2676 if make install is given. Affected files: all Makefile.am's.
2678 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2680 * Assure that silc_client_notify_by_server_resolve does not
2681 resolve the client information multiple times. If it cannot
2682 be found by the first it cannot be found at all. Affected
2683 file lib/silcclient/client_notify.c.
2685 * Fixed WHOWAS command reply calling. Affected file
2686 lib/silcclient/command_reply.c.
2688 * Removed all references to silc_idlist_get_client from the
2689 Irssi SILC client since that call is internal call used by
2690 the library. The Irssi SILC client will use now client
2691 retrieval functions found in silcapi.h.
2693 * Fixed a bug in resolving nickname info before sending
2694 private message. It used freed memory. Affected file
2695 irssi/src/silc/core/silc-servers.c.
2697 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2699 * Assure my_channels statistics cannot go negative in server.
2700 Affected files silcd/server.c, silcd/server_util.c.

2716 * Added silc_net_localip to return local host's IP address.
2717 Affected file lib/silcutil/silcnet.[ch].
2719 * If key exchange or rekey protocol is active for a connection
2720 parse all packets syncronously since there might be packets
2721 in packet queue that we are not able to process without first
2722 processing packets before them. Affected file silcd/server,
2723 lib/silcclient/client.c.
2725 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2726 whether library should continue processing the packet.
2727 Affected file lib/silccore/silcpacket.h.

2773 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
2774 is incomplete and is being resolved, it won't be resolved
2777 Make sure also that USERS command reply does not resolve
2778 twice information. Affected file is
2779 lib/silcclient/command_reply.c.
2781 Make sure that silc_client_get_clients_by_list does not
2782 resolve twice same information.
2784 * Check for valid client->id in the silc_server_free_client_data.
2785 Affected file silcd/server.c.
2787 * Fixed /GETKEY nick@server not to crash if the server entry
2788 is not found. Affected file lib/silcclient/command.c.
2790 * Fixed the silc_server_check_cmode_rights to check the
2791 requested modes correctly. Affected file silcd/command.c.

2796 Affected file silcd/command.c.
2798 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2800 * Call the silc_server_udpate_servers_by_server in the
2801 primary router that comes back online in the backup resuming
2802 protocol. Otherwise it routes packets wrong. Affected file
2803 silcd/server_util.[ch], silcd/server_backup.c.
2805 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2807 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2808 lib/silcutil/silcbuffmt.[ch].
2810 * Redefined the SILC packet header to include the padding
2811 length. Affected file lib/silccore/silcpacket.[ch].
2813 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2814 length for maximum padding up to 128 bytes). Affected
2815 file lib/silccore/silcpacket.h.
2817 * Removed all backwards support for old 0.5.x MAC thingies.
2818 The SILC packet header change makes it impossible to be
2819 backwards compatible.
2821 * Send the ENDING packet with timeout in the backup resuming
2822 protocol. This is to assure that all routers has connected
2823 to the primary router. Affected file silcd/server_backup.c.
2825 * Changed the RNG to take the first IV from random data. It
2826 used to take it from zero actually. Changed the RNG also
2827 to use /dev/urandom during session. /dev/random is used
2828 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2830 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2832 * Changed the SILC packet header to have the first two bytes
2833 (the packet length) encrypted. Affected files aroung the
2834 code tree, lib/silccore/silcpacket.[ch]. Removed the
2835 SilcPacketCheckDecrypt callback. It is not needed anymore
2836 since the silc_packet_receive_process will determine now
2837 whether the packet is normal or special.
2839 * Implemented the unidirectional MAC keys. Affected files
2840 lib/silcske/silcske.c, silcd/protocol.c and
2841 lib/silcclient/protocol.c.
2843 * Implemented the packet sequence number to the MAC computation.
2844 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
2845 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
2846 lib/silcclient/protocol.c.
2848 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2850 * Allow backup router to announce servers. All servers
2851 announced by backup router are added to the global list
2852 automatically. Update hte server's socket to our primary
2853 router also when backup router announces a server.
2854 Affected file silcd/packet_receive.c.
2856 * Do not update the client->router in the function
2857 silc_server_udpate_clients_by_server if the client is on
2858 global list. We might fail to find any specific server
2859 for locally connected clients and local cell clients. They
2860 should still use the `from' and not `to' as client->router.
2861 This fixes backup router resuming protocol. Affected file
2862 silcd/server_util.c.
2864 * Decrease channel statistics count only if the channel
2865 deletion worked. Affected files are silcd/server.c and
2866 silcd/server_util.c.
2868 * Added silc_server_update_servers_by_server to update origin
2869 of all server entries. Used during backup router protocol.
2870 Affected files silcd/server_util.[ch], silcd/server.c. and
2871 silcd/backup_router.c.
2873 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
2874 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
2875 silc_hmac_get_hash and silc_hmac_get_name. Affected file
2876 lib/silccrypt/silchmac.c.
2878 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2880 * Assure that router cannot reroute the same channel message
2881 to the sender. Affected file silcd/packet_receive.c.
2883 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2885 * Made better checks that the channel message is not sent
2886 to the router it came from. Affected file is
2887 silcd/packet_send.c. Fixed memory leak too.
2889 * Announce informations for incoming router connection, but
2890 only after checking if it is replaced by backup router.
2891 Affected file silcd/packet_receive.c.
2893 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2895 * Fixed the backup resuming protocol to work in multiple
2896 router environment. Affected file silcd/server_backup.c.
2898 * Route packet only to one router in the function
2899 silc_server_packet_send_to_channel. Affected file is
2900 silcd/packet_send.c.
2902 * Fixed silc_server_send_notify_dest to set the broadcast
2903 flag. Fixed the silc_server_send_notify_topic to actually
2904 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2905 Affected file silcd/packet_send.c.
2907 * Changed the SFTP Filesystem interface. Changed the
2908 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2909 the filesystem operation function. The SilcSFTPFilesystem
2910 is now a context that is allocated by all filesystem allocation
2911 functions and it already includes the operations structure
2912 and filesystem specific context. It is given as argument
2913 now to the silc_sftp_server_start. This made the interface
2914 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2915 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2917 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2919 * Changed the backup router adding and getting interfaces
2920 in the server. The router that will be replaced by the
2921 specified backup router is now sent as argument. Affected
2922 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2925 * Added silc_net_addr2bin_ne to return the binary form of
2926 the IP address in network byte order. Affected files
2927 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
2929 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2931 * Check for existing server ID in silc_server_new_server
2932 and in silc_server_connect_to_router_final and remove the
2933 old entry if it exists. Affected file silcd/packet_receive.c,
2936 * Send the channel message always to only one router, either
2937 in upstream or downstream. Affected file is
2938 silcd/packet_send.c.
2940 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2942 * Wrote the definition of the backup resuming protocol to the
2943 protocol specification.
2945 * Removed one redundant channel key generation from normal
2946 server during joining procedure. Removed one redundant
2947 channel key sending from server to router during joining
2948 procedure. Affected file silcd/command.c.
2950 * Made minor bugfixes to the backup router resuming protocol.
2951 Affected file silcd/server_backup.c, server.c.
2953 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2955 * Added --disable-asm configuration option. Affected files
2956 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
2959 * Implemented the backup resuming protocol that is used to
2960 resume the primary router position in the cell after the
2961 primary router comes back online. Affected files
2962 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
2963 and silcd/server_util.[ch].
2965 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2967 * Sleep two (2) seconds after sending QUIT command to server.
2968 Affected file lib/silcclient/command.c.
2970 * Assure that if outgoing data buffer is pending do not force
2971 send any data. Affected file silcd/packet_send.c.
2973 * Assure that if outgoing data buffer is pending do not force
2974 send any data. Affected file lib/silcclient/client.c.
2976 * Implemented the backup router support when the primary router
2977 goes down. The servers and routers can now use the backup
2978 router as new primary router without loosing connectivity.
2980 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2982 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
2983 in the server to indicate disabled entry. All data read
2984 from the connection will be ignored and no data is sent
2985 for entry that is disabled. Affected files are
2986 silcd/idlist.h, silcd/server.c.
2988 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2990 * Created SFTP client and server test programs in the
2991 lib/silcsftp/tests directory.
2993 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2995 * Implemented memory filesystem (virtual filesystem) for
2996 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
2999 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3001 * Implemented the SFTP (SSH File Transfer Protocol) to the
3002 lib/silcsftp. It includes SFTP client and SFTP server
3005 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3007 * Moved lib/silccore/silcprotocol.[ch] to the
3008 lib/silcutil library.
3010 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
3011 take variable argument list pointer as argument. Affected
3012 file lib/silcutil/silcbuffmt.[ch].
3014 * Added silc_buffer_set function that is used to set data
3015 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
3016 Affected file lib/silcutil/silcbuffer.h.
3018 * Changed various routines in the core library to use the new
3019 silc_buffer_set instead of allocating new buffer only for
3022 * Added 64-bit value formatting and unformatting support to the
3023 silc_buffer_[un]format routines. Affected file is
3024 lib/silcutil/silcbuffmt.[ch].
3026 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
3027 to includes/bitmove.h.
3029 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3031 * Fixed channel user mode saving in client library. Affected
3032 file lib/silcclient/command[_reply].c.
3034 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3036 * Defined the file transfer to the SILC Protocol. Added
3037 new packet type SILC_PACKET_FTP and defined File Transfer
3038 Payload. The mandatory file transfer protocol is SFTP
3039 (SSH File Transfer Protocol). Affected file in addition
3040 of the internet draft is lib/silccore/silcpacket.h.
3042 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
3043 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
3044 is used as part of backup router protocol when the primary
3045 router of the cell is back online and wishes to resume
3046 the position as primary router.
3048 * Redefined the MAC generation keys in the protocol. The
3049 same key is not used anymore in both direction. Both
3050 direction will now use different keys for sending and
3051 receiving. This fixes a potential security flaw. This
3052 change causes incompatibilities in the protocol.
3054 * Redefined also the MAC computation from the packet.
3055 An packet sequence number is now added to the MAC
3056 computation. This prevents possible replay attacks against
3057 the protocol. This change too causes incompatibilities
3060 Added `sequence' field to the SilcPacketContext to hold
3061 the current sequence number for the packet.
3063 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3065 * Added `created' field to the SilcIDListData in the file
3066 silcd/idlist.h to indicate the time when the entry was
3069 * Added `created' field to the SilcChannelEntry too. Affected
3070 file silcd/idlist.h.
3072 * Added `creation_time' aguments to all the announcement functions
3073 in the server. If it is provided then only the entries that
3074 was created after the provided time frame are actually
3075 announced. Affected file silcd/server.[ch].
3077 * The protocol says that the Channel ID's IP address must be
3078 based on the router's IP address. Added check for this in
3079 the silc_server_new_channel when processing incoming New Channel
3080 Payload. Affected file silcd/packet_receive.c.
3082 * Print out the correct version with --version in SILC client.
3083 Affected file irssi/src/silc/core/silc-core.c.
3085 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3087 * Fixed WHOWAS command to check for completnes of the client
3088 entry always, not just when the command is coming from client.
3089 Affected file silcd/command.c.
3091 * Added new function silc_server_packet_queue_purge to purge the
3092 outgoing data queue to the network. After the function returns
3093 it is guaranteed that the outgoing packet queue is empty.
3094 Affected file silcd/packet_send.[ch].
3096 * Purge the outgoing packet queue in the rekey protocol's final
3097 callback to assure that all rekey packets go to the network
3098 before quitting the protocol. Affected file silcd/server.c.
3100 * Added silc_client_packet_queue_parse as similar function as
3101 in server to the client library. The affected file is
3102 lib/silcclient/client.c.
3104 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3106 * Splitted silcd/server.c and created silcd/server_util.[ch]
3107 for utility functions.
3109 * Added new socket flag SILC_SF_DISABLED to indicate that the
3110 connection is open but nothing can be sent to or received from
3111 the connection. Affected file lib/silcutil/silsockconn.[ch].
3112 The checking for disabled socket is checked in the low level
3113 silc_socket_write and silc_socket_read functions.
3115 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3117 * Allow only nicknames and channel names that fits into the
3118 7-bit unsigned char ASCII set. Affected file silcd/command.c.
3120 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3122 * When processing JOIN command reply in server check that if
3123 the channel exists in our global list we'll move it the local
3124 list. Affected file silcd/command_reply.c.
3126 * Fixed the check whether client is joined on the channel already
3127 in JOIN command. Affected file lib/silcclient/command.c.
3129 * Fixed the JOIN command reply to check whether the channel
3130 already exists. Affected file lib/silcclient/command_reply.c.
3132 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3134 * Added silc_ske_status_string to map the SKE error numbers
3135 to readable strings. The affected files are
3136 lib/silcske/silcske[_status].[ch].
3138 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3140 * Do not show the private channels on the WHOIS channel list
3141 as it is not allowed by the protocol. The affected file is
3144 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3146 * Assure that the packet length digged from the actual packet
3147 is something sensible in the silc_packet_decrypt_rest_special
3148 in lib/silccrypt/silcpacket.c.
3150 * Free and NULL the allocated pointer in silc_hmac_alloc if
3151 the HMAC allocation fails. The affected file is
3152 lib/silccrypt/silchmac.c.
3154 * Print the selected security properties to the log files in
3155 the server. Affected file silcd/protocol.c.
3157 * Add SKE's reference counter even if calling the completion
3158 callback manually. Otherwise it goes negative, although it
3159 does not cause any problems. The affected file is
3160 lib/silcske/silcske.c.
3162 * Remove the client entry with short timeout after giving the
3163 KILL command. Affected file lib/silcclient/command.c.
3165 * Fixed to send error reply in WHOIS and IDENTIFY commands in
3166 case all found clients are already disconnected (WHOWAS would
3167 found them) in the server. Affected file silcd/command.c.
3169 * Update the last_receive (time of last data received) to be
3170 updated only when received private or channel message so that
3171 the idle time showed in WHOIS makes more sense.
3173 * Added boolean field `valid' in to the SilcClientEntry in the
3174 client library to indicate whether the entry is valid or not.
3175 This fixes the nickname change bug on channel when changing
3176 the nickname to be same than the old (like nick to Nick) the
3177 nickname formatter doesn't set the new nick anymore to Nick@host.
3178 Affected file lib/silcclient/idlist.[ch].
3180 * Now actually fixed the nickname changing on disconnection.
3181 Added new function silc_change_nick to the Irssi SILC Client.
3182 Affected file irssi/src/silc/core/client_ops.c,
3183 irssi/src/silc/core/silc-nicklist.[ch].
3185 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3187 * Check that the public key exists in the GETKEY command before
3188 trying to encode it. Affected file silcd/command.c.
3190 * Print some notifications on received public keys with GETKEY
3191 command in the Irssi SILC Client. Affected files are
3192 irssi/src/fe-common/silc/module-formats.[ch],
3193 irssi/src/silc/core/client_ops.c.
3195 * Use IDENTIFY command to resolve the server information in the
3196 GETKEY command instead of INFO command. Affected file
3197 lib/silcclient/command.c.
3199 * All command reply functions in the client library now calls
3200 the pending command reply callbacks even if an error has
3201 occurred. The server has done this a long time and now it was
3202 time to move the client library to this as well. Now all
3203 errors can be delivered back to the pending command reply
3204 callbacks if necessary. Affected files are
3205 lib/silcclient/command[_reply].[ch].
3207 * Change the nickname on disconnection back to the username
3208 because in reconnect the server will enforce it to it anyway.
3209 Affected file irssi/src/silc/core/silc-servers.c.
3211 * Fixed a config file parsing bug in the Irssi SILC client.
3212 Affected file irssi/src/silc/core/clientconfig.c.
3214 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3216 * When printing the channel mode on JOIN, verify that the
3217 channel key and channel's HMAC are valid. Affected file
3218 irssi/src/silc/core/client_ops.c.
3220 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3222 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
3223 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
3224 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
3226 * Removed channel key rekey task deleting from the function
3227 silc_server_save_channel_key. Affected file silcd/server.c.
3228 Added explicit timeout task context instead that is used to
3229 delete the task if we are registering a new task before the
3230 new task has elapsed.
3232 * When channel key rekey occurs the client library now saves
3233 the old channel key for a short period of time (10 seconds) and
3234 is able to use it in case some is still sending channel
3235 messages encrypted with the old key after the rekey. Affected
3236 file lib/silcclient/[idlist.h|client_channel.c].
3238 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3240 * Added check to the silc_server_new_id_real to not accept
3241 new ID if it is the sender's own ID. Affected file is
3242 silcd/packet_receive.c.
3244 * Assure that we do not announce ourself or the one we've
3245 sending our announcements when we're router and are announcing
3246 servers to our primary router. Affected file silcd/server.c.
3248 * Fixed silc_server_command_identify_check_client to assemble
3249 correct WHOIS packet. It send corrupted WHOIS packet and
3250 caused problem with router to router connections. Affected
3251 file silcd/command.c.
3253 Fixed also silc_server_command_whois_check the same way
3254 as for the IDENTIFY command.
3256 * Added new SilcIDListStatus to the server in the SilcIDListData
3257 structure. The status now includes the current status of
3258 the entry (like registered, resolved etc.). Affected file
3259 silcd/idlist.[ch]. Defined a bunch of different status types
3260 as well. This replaced the old boolean registered field as well.
3262 Added resolve_cmd_ident field to the SilcClientEntry structure
3263 too so that if the entry is for example being resolved so
3264 another command may attach to the same pending command reply
3265 without requiring to resolve the same entry again. This concept
3266 should optimize the WHOIS and the IDENTIFY resolving under
3267 heavy load by taking away unnecessary resolving for entries
3268 that are being resolved already.
3270 Added support for adding multiple pending commands for one
3271 command idenfier. Affected file silcd/command[_reply].[ch].
3273 * Fixed WHOIS and IDENTIFY save to remove the cache entry
3274 before deleting the data. Otherwise the hash table will have
3275 freed data in comparison functions. Affected file is
3276 silcd/command_reply.c.
3278 * Fixed silc_idlist_replace_client_id to add the new entry to
3279 the cache with NULL nickname. Otherwise there will be invalid
3280 memory as the nickname after the nickname is freed. Affected
3281 file silcd/packet_receive.c.
3283 * Fixed the silc_idlist_get_clients_by_hash. The entries was
3284 saved into wrong slots because the previous number of entries
3285 was not taken into account. Affected file silcd/idlist.c.
3286 Fixed same thing in silc_idlist_get_clients_by_nickname too.
3288 * If we are router and we receive JOIN notify to a channel that
3289 does not have any users then notified client is marked as the
3290 channel founder, as it is it. The affected file is
3291 silcd/packet_receive.c
3293 * Added to the extended hash table API's table_del_*ext functions
3294 the destructor as argument too, so that the caller can decide
3295 which destructor to use or whether to use destructor at all.
3296 Affected file lib/silcutil/silchashtable.[ch].
3298 * Fixed ID Cache purging. It actually deleted the entries from
3299 the hash table after the data was freed. The hash table ended
3300 up comparing freed memory. The affected file is
3301 lib/silccore/silcidcache.c.
3303 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3305 * Fixed Irssi SILC client's KILL command's HELP syntax.
3307 * The USERS command now resolves the detailed user information
3308 if the userinfo field is missing. Affected file is
3309 lib/silcclient/command_reply.c.
3311 * Do not print error in silc_file_read if the read file does
3312 not exist. Just silently return NULL. Affected file is
3313 lib/silcutil/silcutil.c.
3315 * Fixed the silc_log_output to not wine about NULL filename
3316 and to not create some bogus " " filename. Affected file is
3317 lib/silcutil/silclog.c.
3319 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3321 * Fixed various printing bugs on the user interface in the
3322 Irssi SILC Client. Minor changes that were forgotten from
3325 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3327 * Fixed the configure.in.pre and the compilation and distribution
3328 environment to support the new autoconf 2.52. That version is
3329 now required to compile the CVS trunk.
3331 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3333 * Renamed function silc_parse_nickname to silc_parse_userfqdn
3334 to generally parse user@fqdn format strings. Affected file
3335 lib/silcutil/silcutil.c.
3337 * Added nickname_format and nickname_force_format fields to the
3338 SilcClientParams structure. The first one defines the format
3339 for the nicknames that the library will enforce if the receives
3340 multiple same nicknames. The second one is boolean value and
3341 can be used to force the library to always enforce the format
3342 to the nicknames regardles whether there are multiple nicknames
3343 or not. This configurable formatting was employed to flexibly
3344 support accessing multiple nicknames from the user interface.
3345 The userinterface can now set the nicknames to what ever format
3346 they prefer. Affected file lib/silcclient/silcapi.h.
3348 Added function silc_client_nickname_format to the file
3349 lib/silcclient/idlist.c. It performs the nickname formatting.
3351 Added new field `hostname´ to the SilcClientEntry context.
3352 It holds the hostname of the client. Affected file is
3353 lib/silcclient/idlist.h.
3355 * Irssi SILC Client sets the nicknames in nick@hostn format.
3356 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
3357 irssi/src/silc/core/silc-core.c.
3359 The WHOIS printing now also shows both the real nickname and
3360 the formatted nickname so that user knows how to access the
3361 user if there are multiple same nicknames cached. Affected
3362 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
3363 printing formatting too to take the hostname now as a separate
3364 argument. The Affected file is
3365 irssi/src/fe-common/silc/modules-formats.[ch].
3367 * Changed the silc_client_get_clients_local to accept the formatted
3368 nickname as argument. It accepts the real nickname too but the
3369 formatted nickname can be used to find the true entry from
3370 multiple entries. Affected file lib/silcclient/silcapi.h and
3371 lib/silcclient/idlist.c.
3373 * Added nickname_format_parse field to the SilcClientParams.
3374 It is a callback function provided by the application to parse
3375 the nickname out of the formatted nickname string. The library
3376 calls it to get the nickname from the formatted string. Since
3377 the application generally knows better the format of the nickname
3378 string it parses it instead of the library, even though library
3379 encodes the formatted string. If the callback function is not
3380 provided then the library will use the string as is. The
3381 affected file is lib/silcclient/silcapi.h.
3383 * All the nickname strings passed to the client library in
3384 commands are now expected to be formatted nickname strings.
3385 If the command does not support the formatted nickname string
3386 it will assume that the sent string is the actual nickname.
3387 Affected file lib/silcclient/command.c.
3389 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3391 * Added public key authentication support to OPER and SILCOPER
3392 commands in the client library. Affected file is
3393 lib/silcclient/command.c.
3395 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3397 * Changed the get_auth_methdod client operation to be asynchronous.
3398 It can be async if the application resolves the authentication
3399 method from the server during the negotiation. Added new
3400 SilcGetAuthMeth completion callback that the application will
3401 call after resolving the authentication method.
3403 Added function silc_client_request_authentication_method that
3404 the application can use to resolve the authentication method
3405 from the server. Added also SilcConnectionAuthRequest callback
3406 that the library will call after the server has replied. The
3407 application can call this function if it does not know the
3408 current authentication method.
3410 Affected files are lib/silcclient/client.c and
3411 lib/silcclient/silcapi.h.
3413 * The Irssi SILC client now automatically resolves the authentication
3414 method incase any configuration information is not present (and
3415 currently there never is). The affected file is
3416 irssi/src/silc/core/client_ops.c.
3418 * Fixed public key authentication from the client library.
3419 Affected file lib/silcclient/protocol.c. Changed also the
3420 protocol specification about the public key authentication in
3421 the connection authentication protocol. The actual data to be
3422 signed is now computed with a hash function before signing.
3424 * Fixed the public key authentication from the server as well.
3425 Affected file silcd/protocol.c.
3427 * Removed the mlock()'s from the memory allocation routines.
3428 Affected file lib/silcutil/silcmemory.c. The ./configure does
3429 not check anymore for the mlock(). Affected file is
3432 * Fixed USERS command in server to allow the execution of the
3433 command for private and secret channels if the client sending
3434 the command is on the channel. Affected file silcd/command.c.
3436 * Fixed silc_client_get_clients_local to return the clients
3437 count correctly. It could return wrong value. Affected file
3438 lib/silcclient/idlist.c.
3440 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3442 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
3443 types. The assembler optimizations seemed not to like 64-bit
3444 data types. The assmebler optimizations thus are now enabled
3445 also for BSD systems as opposed to only enable them for Linux.
3447 * Do not check for threads at all on BSD systems. Affected
3448 file configure.in.pre.
3450 * Removed -n and -h options from the Irssi SILC Client since
3451 they are not used in silc.
3453 * Fixed the prime generation to assure that the first digit
3454 of the generated random number is not zero since our conversion
3455 routines does not like number strings that starts with zero
3456 digit. If zero digit is seen the random number is regenerated.
3457 This caused some corrupted RSA keys when the zero first digit
3458 was met. Affected file lib/silcmath/silcprimegen.c.
3460 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3462 * Fixed WIN32 configuration in the ./configure script.
3463 Fixed to include xti.h on environments that has it.
3464 Patches by Carsten Ilchmann and andrew.
3466 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3468 * Changed the silc_id_create_client_id to be collision
3469 resistant. It is now assured that there cannot be created
3470 two same client ID's. I suspect that some weird bugs in
3471 the server were actually caused by duplicate Client IDs.
3472 Affected file silcd/serverid.[ch]. A router receiving
3473 new ID now also assures and informs the sending server
3474 if the ID caused collision.
3476 * Changed the silc_id_create_channel_id to also assure that
3477 there are no collisions.
3479 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3481 * Statement about ignoring the Mutual Authentication flag when
3482 performing rekey with PFS was a bit misleading. It is ignored
3483 if it was set in the initial negotiation, it cannot be even
3484 set in the rekey. Fixed in the ke-auth draft. Started the
3485 new versions of the protocol drafts in the doc/.
3487 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3489 * Fixed a bug in silc_client_command_identify_save when saving
3490 new channel information. The channel name was no duplicated
3491 and caused crash on exit. Affected file is
3492 lib/silcclient/command_reply.c.
3494 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3496 * Fixed the getkey command handling in the server. Send just
3497 empty OK reply to the sender if the key could not be fetched
3498 (but everything else was ok, like the key just was not available).
3499 Changed the public key parameter to optional in the protocol
3500 specs so that empty OK reply can be sent. Affected file
3503 Added a message to Irssi SILC client to tell to user if the
3504 server did not return a public key.
3506 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3508 * Fixed a channel key regeneration bug. It registered new
3509 timeout tasks exponentially until all system resources were
3510 used. Affected file silcd/server.c.
3512 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3514 * Added the SILC Document generator to the scripts/silcdoc.
3515 It can be used to generate the Toolkit Reference Manual out
3516 of the source tree. Internally it will also use the RoboDoc
3517 generator now imported in util/robodoc.
3519 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3521 * Added couple of return's in rekey protocol if error orccurred
3522 during the protocol. The execution must be terminated.
3523 Affected file silcd/protocol.c. Also, terminate the protocol
3524 always with timeout.
3526 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3528 * The client's Client ID was created initally from the wrong
3529 nickname (it could have been in format nick@host) in the
3530 silc_server_new_client. Affected file silcd/packet_receive.c
3532 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3534 * Added some SILC_LOG_ERROR's to various error conditions
3535 if client could not be added to ID cache. Affected files
3536 silcd/packet_receive.c and silcd/server.c.
3538 * When client's sock->user_data is freed, NULL also the
3539 client->router and client->connection pointers. Added check
3540 for these pointers being NULL to various places around the
3541 code. Affected file silcd/server.c.
3543 * Added client->data.registered == TRUE checks to various
3544 places around the code to assure that unregistered client's
3545 are not handled when it is not allowed. Affected file
3548 * Added `bool registered' fields to all
3549 silc_idlist_[server|client]_get_* routines to indicate whether
3550 the fetched client needs to be registered or not. Affected
3551 file silcd/idlist.[ch].
3553 * Add your own entry as registered to the ID cache in the
3554 server. Affected file server.c.
3556 * Fixed a bug in silc_server_new_server. The SilcServer was
3557 set as the new server's context instead of SilcServerEntry.
3558 This naturally caused some weird bugs.
3560 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3562 * Do not delete the channel rekey task when adding it
3563 for in silc_server_create_channel_key.
3565 * Changed the silc_server_create_channel_key to return
3566 TRUE or FALSE to indicate the success of the channel key
3569 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3571 * Fixed MSVC++ project files and added missing files to
3572 Makefiles under win32/.
3574 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3576 * Do not add TCP_NODELAY flag if the operating system
3577 does not have it defined. Affected files are
3578 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3580 * Fixed buffer overflow from Irssi SILC Client. Affected
3581 file irssi/src/fe-common/core/themes.c.
3583 * Fixed double free in client library in the file
3584 lib/silcclient/client.c when disconnecting from server.
3586 * Applied double free patch from cras to Irssi SILC client.
3587 Affected files irssi/src/core/[modules/expandos].c
3589 * Fixed the disconnection handling to Irssi SILC Client.
3590 The application must call silc_client_close_connection
3591 in ops->connect client operation in case of failure of
3592 the connection. Affected file is
3593 irssi/src/silc/core/client_ops.c.
3595 * Do not set sock->protocol to NULL in the function
3596 silc_client_close_connection after executing the protocol's
3597 final callback since the sock might not be valid anymore.
3598 Affected file lib/silcclient/client.c.
3600 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3602 * Do not enable SILC_THREADS if the linking with libpthread
3603 did not happen. Affected file configure.in.pre.
3605 * Added notion to protocol specification that server must
3606 verify the sent authentication payload with CMODE when
3607 setting the channel founder key. Implemented it to the
3608 server. Affected file silcd/command.c.
3610 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3612 * Added _EXTRA_DIST SILC distribution variable to the
3613 distributions file. It is used to conditionally add extra
3614 files or directories to the specific distribution. Affected
3615 files ./prepare, Makefile.am.pre and distributions.
3617 Removed the `_' from the start of the distribution names.
3620 * Added README.WIN32 for instructions to compile the Toolkit
3623 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3625 * Fixed a double free in disconnection in the server. Affected
3626 file is silcd/server.c.
3628 * Fixed the lib/silcske/groups.c to work now also with GMP
3629 MP library. The string conversion did not work when using
3630 specific base and the base is indicated in the string as well.
3632 * Created win32/ directory which now includes MSVC++ specific
3633 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3634 It will appear only in the toolkit distribution
3636 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3638 * Changed the key material distribution function in case when
3639 the hash output is too short. The data is now concatenated
3640 a bit differently than it used to. Made the change to the
3641 SKE protocol specification.
3643 * Added better GMP detection to configure.in.pre. A patch
3646 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3648 * Fixed a minor bug in SKE that might cause some problem on
3649 some platforms. Affected file lib/silcske/silcske.c.
3651 * Added the cookie checking for initiator in the SKE. It checks
3652 that the responder returns the sent cookie unmodified. The
3653 affected file is lib/silcske/silcske.c. Added new SKE
3654 error type INVALID_COOKIE that can be sent during the
3655 negotiation. Fixed some memory leaks as well.
3657 * Added the "invalid cookie" error message to Irssi SILC client's
3660 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3662 * Added `task_max' field to the SilcClientParams to indicate
3663 the maximum tasks the scheduler can handle. If set to zero,
3664 default values are used. Affected file lib/silcclient/silcapi.h.
3666 * Fixed memory leaks in silc_client_close_connection. Affected
3667 file lib/silcclient/client.c.
3669 * Added silc_client_del_client_entry to client library to free
3670 all memory of given client entry. Affected file is
3671 lib/silcclient/idlist.[ch].
3673 * Added new functions silc_client_del_channel and
3674 silc_client_del_server to delete channel and server entries.
3675 Affected file lib/silcclient/[silcapi.h/idlist.c].
3677 * Removed silc_client_del_client_by_id from silcapi.h.
3679 * Fixed the INFO command to return the server's own info
3680 correctly when querying by Server ID. Affected file is
3683 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3685 * Removed the non-blocking settings in WIN32 code in the
3686 silc_sock_[read/write] and added SleepEx instead. Affected
3687 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3688 of input data is now checked with FIONREAD and ioctlsocket.
3690 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3692 * Call silc_schedule_task_del_by_context in the
3693 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3694 Affected file lib/silccore/silcprotocol.c.
3696 * Call silc_protocol_cancel for active protocols in the
3697 silc_server_close_connection if the funtion
3698 silc_server_free_sock_user_data has not been called.
3699 Affected file silcd/server.c.
3701 * Generic tasks cannot be deleted using the del_by_fd
3702 task deleting function since generic tasks does not match
3703 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3705 * Added a notion to SILCOPER help file that the SILCOPER works
3706 only on router server, not on normal server.
3708 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3710 * Added for WIN32 support for the new scheduler as well.
3711 Affected file lib/silcutil/win32/silcwin32schedule.c.
3713 * Fixed the SHA1 implementation to work on various platforms.
3715 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3717 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3718 API. It is part of the scheduler now. Everything else is
3719 as previously but some functions has changed their names.
3720 Checkout the lib/silcutil/silcschedule.h for the interface.
3721 Updated all applications to use the new interface. Affected
3722 files are lib/silcutil/silcschedule.[ch].
3724 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3726 * Found a bug in the SKE implementation. The HASH value,
3727 specified by the protocol, was not computed correctly. The
3728 public key of the responder was not added to the computation
3729 even though it is mandatory. Affected file lib/silcske/silcske.c.
3730 This unfortunately causes incompatibilities with older
3731 clients and servers.
3733 * Added WIN32 specific network init and uninit functions:
3734 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3735 the Winsock2. Affected file lib/silcutil/silcnet.h and
3736 lib/silcutil/win32/silcwin32net.c.
3738 * Set the socket always to nonblocking mode on WIN32 after
3739 reading data or writing data. Affected file is
3740 lib/silcutil/win32/silcwin32sockconn.c.
3742 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3744 * Fixed various compilation problems under WIN32. Affected
3745 files lib/silcutil/win32/silcwin32thread.c and
3746 lib/silcutil/win32/silcwin32schedule.c.
3748 * Removed all _internal.h #includes from public header
3749 files. Internal headers must never be included from
3752 Removed also the lib/silcske/payload_internal.h file.
3754 * All include files that may be needed (public and some others
3755 included by the public headers) by application developers are
3756 now copied to the ./includes directory. It does not copy any
3757 internal headers. Affected file Makefile.defines.pre and all
3758 Makefile.am's under lib/ and subdirs.
3760 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3762 * Do not change the ~/.silc directory's permissions automatically.
3763 Affected file irssi/src/silc/core/clientutil.c.
3765 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3767 * Do not cancel the protocol in silc_server_close_connection
3768 it might cause recursion. Now cancelled in the function
3769 silc_server_free_sock_user_data. Affected file silcd/server.c.
3771 * Fixed the silc_server_remove_clients_by_server to regenerate
3772 the channel keys correctly finally. Added also new function
3773 silc_server_remove_clients_channels to actually do it.
3774 Affected file silcd/server.c.
3776 * Fixed the silc_server_new_channel to not crash by giving
3777 wrong router to the new channel. Affected file is
3778 silcd/packet_receive.c.
3780 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3782 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3783 which is given as argument to the silc_client_alloc now.
3784 It can be used to configure the client and set various parameters
3785 that affect the function of the client.
3787 * The USERS command in server did not check whether the channel
3788 is private or secret. Affected file silcd/command.c.
3790 * Added new argument to the USERS command in protocol specification.
3791 The USERS command now can take the channel name as argument
3792 as well. Added support for this in client and server and
3793 updated the protocol specs.
3795 * Completed the GETKEY command in client. It can be now used
3796 to fetch also servers public key not only some clients.
3797 Affected files lib/silcclient/command[_reply].c.
3799 * Added silc_client_get_server to return server entry by the
3800 server name. Affected files lib/silcclient/silcapi.h and
3803 * Redefined the IDENTIFY command in protocol specification to be
3804 more generic. It now can be used to query information about
3805 any entity in the SILC Network, including clients, servers and
3806 channels. The query may be based either the entity's name
3807 or the ID. Added support for this in both client and server.
3809 Affected files silcd/command.c and lib/silcclient/command.c
3810 and command_reply.c.
3812 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3813 the _from_client and _from_server functions. Affected file
3816 * Added silc_client_get_channel_by_id_resolve to the file
3817 lib/silcclient/silcapi.h to resolve channel information by
3818 its ID. Added also silc_client_get_channel_by_id that
3819 does not resolve it from the server.
3821 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3823 * Added SilcServerEntry context into the client library
3824 to represent one server. The INFO command now allocates
3825 these to save the resolved server info. For now on the
3826 client library will also keep information about servers,
3827 connected and resolved with INFO.
3829 The INFO command now allocates the SilcServerEntry context
3830 and saves the server info there. The COMMAND_REPLY in
3831 the INFO now returns the parameters to application in
3832 same order as defined in the protocol specification.
3834 The entries are cached in the client->server_cache.
3836 * The INFO command is now issued after received the Client ID
3837 from the server. Affected file lib/silcclient/client.c.
3839 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3840 to the application as the mode changer might be server.
3841 It is guaranteed that NULL is not returned anymore to the
3842 application. Affected file lib/silcclient/client_notify.c.
3844 The ID Type is now also passed to the application so that
3845 it can check whether the returned entry is SilcClientEntry
3848 Added new function silc_client_get_server_by_id to return
3849 the server entry by ID. Affected files are the
3850 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3852 * Do not create the channel in the Irssi SILC Client when issuing
3853 the JOIN command but when received the sucessful JOIN command
3854 reply. Otherwise the channel might get created even though we
3855 could not join it. The Affected file is
3856 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3858 * Fixed a channel joining bug in router. The router must also
3859 check the channel modes, invite and ban lists etc. when serving
3860 the JOIN command sent by normal server. Affected file is
3861 silcd/command.c. The router now resolves the client's
3862 information from the server who sent the JOIN command if it
3863 does not know it, and processes the JOIN command only after
3866 * Changed the SilcCommandCb to take new argument; void *context2.
3867 Affected file lib/silccore/silccommand.h
3869 The second argument in the command callbacks in the server now
3870 includes the SilcServerCommandReplyContext if the command was
3871 called as pending command callback from the command reply.
3872 Otherwise it is NULL. When called as pending the status of the
3873 command reply will be checked and if it was erronous the
3874 error will be sent to the original sender of the command.
3875 This way the client always receives the error messages even
3876 though the server was actually the one who received the error
3877 when it resent the command to router, for example. Affected
3878 files silcd/command[_reply].[ch].
3880 * Fixed sending WHOWAS command's error message to client if
3881 the requested client could not be found. It was missing.
3884 * Changed the CMODE and CUMODE commands reply arguments in the
3885 protocol specification. The Channel ID is now sent in both
3886 of the commands to identify the channel. Implemented this
3887 new feature to the client and server. Affected files
3888 lib/silcclient/command_reply.c and silcd/command.c.
3890 * Made better checks for invite and ban lists in the JOIN
3891 command in server. Affected file silcd/command.c.
3893 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3895 * The server now performs the incoming host IP/DNS lookup
3896 using the silc_socket_host_lookup and thus does not block
3897 the server anymore. Affected file silcd/server.c.
3899 * Completed the multi-thread support for SILC Scheduler in
3900 the lib/silcutil/silcschedule.c.
3902 * Fixed the configure.in.pre to detect the pthread correctly
3905 * Fixed a deadlock in silc_task_queue_wakeup in the file
3906 lib/silcutil/silctask.c.
3908 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3910 * Added new function silc_schedule_wakeup that is used in
3911 multi-threaded environment to wakeup the main thread's
3912 schduler. It needs to be used when a thread adds a new task
3913 or removes a task from task queues. After waking up, the
3914 scheduler will detect the task queue changes. If threads
3915 support is not compiled in this function has no effect.
3916 Implemented the wakeup mechanism to both Unix and WIN32
3917 systems. Affected files are lib/silcutil/silcschedule.[ch],
3918 lib/silcutil/unix/silcunixschedule.c and the
3919 lib/silcutil/win32/silcwin32schedule.c.
3921 * Added new function silc_task_queue_wakeup to wakeup the
3922 scheduler by the specified task queue. Affected file
3923 lib/silcutil/silctask.[ch].
3925 * The silc_socket_host_lookup_start now wakes up the scheduler
3926 after adding the timeout task. Affected file is
3927 lib/silcutil/silcsockconn.c.
3929 * The silc_socket_host_lookup is synchronous now if the threads
3930 support is not compiled in. However, the callback is still
3931 called asyncronously through the scheduler, anyway. Affected
3932 file lib/silcutil/silcsockconn.c.
3934 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3936 * Added new function silc_socket_host_lookup to perform
3937 asynchronous IP and FQDN lookups for the socket connection.
3938 Affected files lib/silcutil/silcsockconn.[ch].
3940 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3942 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3943 that may or may not compile the mutex support in.
3945 Changed the silc_mutex_alloc interface. It allocates the
3946 mutex now to the sent pointer and returns TRUE or FALSE.
3948 Affected file lib/silcutil/silcmutex.h.
3950 * Wrote the SILC Task Queue interface to support multi-threads.
3951 Affected file lib/silcutil/silctask.[ch].
3953 * Wrote the SILC Scheduler to support multi-threads. Affected
3954 file lib/silcutil/silcschedule.c.
3956 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3958 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3959 in lib/silcutil/win32/.
3961 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3963 * Defined SILC Mutex API and SILC Thread API and implemented
3964 them for Unix. Affected files are
3965 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3966 lib/silcutil/unix/silcunixmutex.c and
3967 lib/silcutil/unix/silcunixthread.c.
3969 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3971 * Fixed the silc_server_remove_clients_by_server's channel
3972 key re-generation. The hash table handling was incorrect
3973 and would not work with many channels. Affected file is
3976 * Fixed some memory leaks around the server code.
3978 * Rewrote the silc_server_get_users_on_channel to support IPv6
3979 based Client ID's. Affected file silcd/server.c.
3981 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3982 specification. However, a separate document must be written
3983 to define the detailed signing procedure and the payload
3984 associated with the flag. Defined the flag to the
3985 lib/silccore/silcchannel.h as well.
3987 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3989 * Changed the dynamic tables to static size tables in the
3990 lib/silccrypt/silchmac.c.
3992 * Removed GCC dependencies from the code. A patch by cras.
3994 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3996 * Do not show the error "Error receiving packet bla bla"
3997 in server if it really was not an error (-2 means that reading
3998 is pending). Affected file silcd/server.c.
4000 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4002 * Fixed a possible crash in silc_server_remove_clients_by_server
4003 in silcd/server.c. Fixed there also some memory leaks.
4005 * Fixed the silc_idlist_replace_client_id. It could replace
4006 wrong key in the hash table. Affected file silcd/idlist.c.
4008 * Do not check whether there are global users on the channel
4009 if the channel->global_users is FALSE. Affected functions
4010 silc_server_remove_from_one_channel and
4011 silc_server_remove_from_channels in silcd/server.c. Also,
4012 do not check if the removed client is local as we can be
4013 sure that global client was not removed from the channel
4014 and checking for global users is not needed.
4016 * The silc_server_remove_clients_by_server now re-generates
4017 the channel keys correctly for those channels that had
4018 clients removed from them. Affected file silcd/server.c.
4020 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4022 * Found the reason of random crashes in the server. We weren't
4023 ignoring the SIGPIPE signal (which can be sent in write())
4024 and it crashed the server. Affected file silcd/silcd.c.
4026 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4028 * Assure that sock->user_data is not NULL in the function
4029 silc_server_packet_send in silcd/packet_send.c.
4031 * Disconnect the remote connection if it could not be added
4032 to any ID lists in the server. The affected file is
4035 * Check in silc_server_packet_send[_real/dest] that the
4036 socket is not disconnecting and ignore the data if it is.
4037 Affected file silcd/packet_send.c.
4039 * Define inline to __inline on native WIN32 compilation.
4040 Affected file includes/silcwin32.h.
4042 * Added some explicit type casts for inline code since MSVC
4043 require them. Affected files lib/silcutil/silcbuffer.h,
4044 lib/trq/silcdlist.h and lib/trq/silclist.h.
4046 * Print warning in log files from now on if the packet
4047 decryption fails. Affected file silcd/server.c.
4049 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4051 * Changed the `say' client operation's interface to accept
4052 new `type' argument to indicate the type of the message sent
4053 by the library. The application may filter the library's
4054 messages according the type. The affected file is the
4055 lib/silcclient/silcapi.h.
4057 * Added two new functions to lib/silcclient/silcapi.h:
4058 silc_client_del_client and silc_client_del_client_by_id.
4059 Affected file lib/silcclient/idlist.c.
4061 * Moved the clientincludes.h from includes/ to silc/ and
4062 serverincludes.h from includes/ to silcd/.
4064 * The modes for the CMODE and CUMODE are now passed as
4065 uint32 for application with COMMAND_REPLY. The affected
4066 file is lib/silcclient/command_reply.c.
4068 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4070 * /WHOIS without arguments shows client's own information.
4071 Affected file lib/silcclient/command.c.
4073 * Changed PING to not accept any arguments. The specs
4074 says that client can ping only the connected server so
4075 requiring an argument is not needed. Affected file is
4076 lib/silcclient/command.c.
4078 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4080 * Fixed a fatal bug in private message sending and reception
4081 encryption and decryption when using private message keys.
4082 The implementation was incorrect and did not follow the
4083 specification. It causd that some of the message were
4084 lost since it did not use the sending and receiving keys
4085 as the protocol suggests. This has been fixed and will cause
4086 incompatibilities with older clients when sending private
4087 message encrypted with private message keys. Affected files
4088 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
4089 and various other in Irssi SILC Client.
4091 Added `responder' boolean argument to the functions
4092 silc_client_add_private_message_key[_ske] to indicate when
4093 the key is added as responder or initiator of the key
4096 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4098 * Removed the silc_ske_check_version function and created
4099 a SilcSKECheckVersion callback. Added also a function
4100 silc_ske_set_callbacks that is now used to set all SKE
4101 callbacks. The callback functions are not given to
4102 the SKE functions anymore, but this function is used to
4105 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
4107 * Added `silc_version' argument to the silc_client_alloc
4108 to define the version of the application for the library.
4109 The library will use the version string to compare it
4110 against the remote host's (usually a server) version
4111 string. Affected file lib/silcclient/silcapi.h
4113 * Added the KE protocol context to Key Agreement context
4114 in client library so that we can abort the SKE if it
4115 is in process when we get timeout. Affected file is
4116 lib/silcclient/client_keyagr.c.
4118 * Do not resolve the client ID forever if it returns in the
4119 first time that such client does not exist. This was done
4120 for example with private message. Affected file is
4121 lib/silcclient/client_prvmsg.c.
4123 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4125 * Do not add regex.h for WIN32. The affected file
4126 includes/silcincludes.h.
4128 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
4129 not work yet 100%. It generates the DLL's automatically
4130 when compiling with --with-win32 under cygwin.
4132 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4134 * lib/contrib/regex.c is not compiled on WIN32.
4136 * Added silc_net_get_socket_opt function to the
4137 lib/silcutil/silcnet.h.
4139 * Added includes/silcwin32.h for WIN32 specific includes
4142 * Do not use ptime structure or any of the posix process
4143 functions on WIN32 in lib/silccrypt/silrng.c.
4145 * Added silc_gettimeofday to provide generic function
4146 for struct timeval on all platforms. Added the function
4147 to lib/silcutil/silcutil.h.
4149 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4151 * Moved the lib/silccore/silcsockconn.[ch] to the utility
4152 library as they clearly belong there. As a plus side we
4153 can make the actual socket connection routines platform
4156 Added also new generic function silc_socket_read and
4157 silc_socket_write (that used to be silc_packet_[read/write].
4158 The implementation of these are platform specific.
4160 * Added WIN32 specific routines of silc_socket_[read/write]
4161 to lib/silcutil/win32/silcwin32sockconn.c.
4163 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4165 * Added preliminary support for native WIN32 compilation under
4166 cygwin (using the -mno-cygwin option for GCC) to the
4167 ./configure.in.pre. The --with-win32 now prepares the
4168 compilation for native WIN32.
4170 * Rewrote the SILC Scheduler interface in the file
4171 lib/silcutil/silcschedule.h. The scheduler is now context
4172 based and does not have anymore any global static scheduler.
4173 Moved the Unix scheduler to the lib/silcutil/unix/ directory
4174 and created lib/silcutil/win32 directory for WIN32 based
4177 * Added Unix specific network routines to the
4178 lib/silcutil/unix/silcunixnet.c and the old
4179 lib/silcutil/silcnet.c includes now only generic routines.
4181 Added WIN32 specific network routines to the
4182 lib/silcutil/win32/silcwin32net.c.
4184 * Added Unix specific utility functions from the
4185 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
4187 * Added WIN32 SILC Scheduler to the file
4188 lib/silcutil/win32/silcwin32schedule.c. The code is of course
4191 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4193 * Do not handle JOIN notify in the server if the target client
4194 is not registered (idata->registered == FALSE). The affected
4195 file is silcd/packet_receive.c.
4197 * Update the nickrec->founder in event_cumode in the Irssi SILC
4198 client. Affected file irssi/src/silc/core/silc-channels.c.
4200 * Fixed the CUMODE_CHANGE notify handling in the server when
4201 server and router are announcing their clients on channels.
4202 Now the mode changes are saved and notified correctly. The
4203 affected file is /silcd/packet_receive.c.
4205 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
4206 They really did not replace the cache entry in the ID Cache.
4207 Now they do that. Affected file silcd/idlist.c.
4209 * Fixed the KICK notify handling in the Irssi SILC client to
4210 update the channel records so that the kicked client does not
4211 appear to be on the channel. The affected file is
4212 irssi/src/silc/core/silc-channels.c.
4214 * Always update the conn->current_channel when executing command
4215 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
4217 * Fixed the KILL notify handling in Irssi SILC client to remove
4218 the killed client on all channels.
4220 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4222 * Fixed the silc_parse_command_line to remove extra spaces
4223 from the start and end of the arguments. Affected file is
4224 lib/silcutil/silcutil.c.
4226 * Cancel and free any active protocol in the function
4227 silc_server_close_connection. Affected file silcd/server.c.
4229 * Cancel and free any active protocol in the function
4230 silc_client_close_connction. Affected file is
4231 lib/silcclient/client.c.
4233 * Do not execute the KILL command for clients that are in
4234 history (ie. they are not in the network). Affected file is
4237 * Fixed KILL notify handling, client does not crash anymore.
4238 Affected file irssi/src/silc/core/silc-channels.c.
4240 * Reduced the default packet buffer size from 2048 to 1024 in
4241 lib/silccore/silcpacket.c.
4243 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
4244 counter to the SKE context that is incresed when the SKE library
4245 performs async operation outside the library. If the outside
4246 process frees the SKE context and FREED status will be set
4247 and the library will detect after the sync operation that the
4248 libary is freed. The affected files are
4249 lib/silcske/silcske[_status].[ch].
4251 * Resolve the client entry information in the function
4252 silc_client_channel_message to assure that NULL pointer is not
4253 passed as client entry to the application. */
4255 * Fixed the task timeout calculation to assure that there is
4256 never negative timeouts. The affected file is
4257 lib/silcutil/silcschedule.c.
4259 * Fixed the channel user mode notification sending in server.
4260 It was sent point-to-point to the router (or to server by router)
4261 but it needs to be destined to a channel. The routines now
4262 supports sending the channel user mode notifys to the channels
4263 when announcing clients and channels. Affected files are
4264 silcd/server.c and silcd/packet_receive.c.
4266 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
4267 It did not actually replace the old channel entry in the cache.
4268 Affected file lib/silcclient/client_notify.c.
4270 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4272 * Fixed a possible crash in silc_packet_send_prepare. It now
4273 assures always that there is enough space in the buffer and
4274 at the tail area of the buffer (for MAC).
4276 Fixed the inbound buffer reallocation in silc_packet_read.
4277 It was old code and did not handle the reallocation correctly.
4280 The affected file is lib/silccore/silcpacket.c.
4282 * Fixed buffer overflow in silc_parse_nickname in the file
4283 lib/silcutil/silcutil.c.
4285 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4287 * make install generates new server keys only if there is not
4290 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4292 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
4293 Added check that if the NOREPLY is set then we will not send
4294 the away message. This avoids infinite loop of away messages
4295 if both clients are away. The affected file is
4296 lib/silcclient/client_prvmsg.c.
4298 * Fixed client crash if /NICK was given without arguments.
4299 Affected file lib/silcclient/command.c.
4301 * Server does not send the invite list in INVITE command back
4302 to the client if the list was not altered. Added this notion
4303 to the protocol spec as well. Affected file silcd/command.c.
4305 Fixed possible crash in INVITE command by checking the
4306 value of silc_server_get_client_route command.
4308 * Fixed the INVITE notify type handling. The arguments are now
4309 taken in correct order and client does not crash. The affected
4310 file is irssi/src/silc/core/silc-channels.c.
4312 Removed the "Inviting xxx to channel" message from the
4313 client library away and let the application handle it.
4314 Affected file lib/silcclient/command.c. Added that message
4315 to Irssi SILC client's message formats.
4317 * Fixed CMODE command crash in client. It now checks the
4318 amount of arguments correctly and does not crash. The affected
4319 file is lib/silcclient/command.c.
4321 * Do not create new channel automatically in silc_channels_join
4322 but check whether the channel by that name already exists.
4323 Affected file irssi/silc/core/silc-channels.c.
4325 * Do not send the SERVER_SIGNOFF to router if the disconnected
4326 entity was the router. Affected file silcd/server.c.
4328 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
4329 SILC client as it was missing from there.
4331 Added the handling of the KICK notify to the Irssi SILC client
4332 as it was missing. Added "you have been kicked" message to
4333 Irssi SILC client's message modules formats.
4335 Added the handing of the KILL notify to the Irssi SILC client
4336 as it was missing. Added the kill message module formats
4339 The affected file is irssi/src/silc/core/silc-channels.c.
4341 * The router did not save the channel mode the server announced.
4342 Affected file silcd/packet_receive.c.
4344 * Fixed a possible crash in INFO command in server. If the
4345 server did not provide the server info it crashed. Affected
4346 file silcd/command.c.
4348 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4350 * Fixed the GETKEY command in the server to check also the
4351 global list. Otherwise the GETKEY would not work correctly
4352 in normal SILC server. Affected file silcd/command.c.
4354 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4356 * Fixed GETKEY crash, it crashed if the command did not succseed.
4358 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4360 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
4361 is now real and not just an macro interface to GMP.
4363 Removed the entire GMP from the source tree and imported new
4364 NSS MPI library instead. Reason for removing GMP is that it is
4365 extremely large and compiles extremely slow. The NSS MPI
4366 is only a few files and compiles in less than 10 seconds.
4367 The speed is also about the same as GMP. The MPI is imported
4368 to lib/silcmath/mpi.
4370 If the system has GMP installed we will still use the GMP.
4371 If it is not then the NSS MPI will be compiled.
4373 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4375 * Merged a long nickname (127 characters long) crash bugfix from
4376 Irssi CVS tree. Affected file irssi/src/core/misc.c.
4378 * Merged a freed memory reference bugfix from Irssi CVS tree.
4379 Affected file irssi/src/core/commands.c.
4381 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4383 * Added the server's public key sving and verification to the
4384 server when performing the SKE. This was missing and the
4385 remote server's (or router's) public key was accepted without
4386 checking whether we have it previously or trust it at all.
4387 Affected file silcd/protocol.c.
4389 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4391 * Check in the silc_server_timeout_remote if protocol is active
4392 and make sure that the protocol's final callback is called so
4393 that all memory if freed. Affected file silcd/server.c.
4395 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4397 * silc_server_whois_send_reply crashed the server if the nickname
4398 was 127 characters long. Affected file silcd/command.c.
4400 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4402 * Added sanity check to the silc_server_new_client. If the hostname
4403 is provided inside username then check that the provided hostname
4404 really is the same as the resolved one. If the hostname was not
4405 resolved then check it from the public key. Affected file is
4406 silcd/packet_receive.c.
4408 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
4409 if the server disconnected us and the connection is not valid
4410 anymore. Affected file irssi/src/silc/core/silc-channels.c.
4412 * Moved the silc_client_[chmode|chumode|chumode_char] away from
4413 the library to the lib/silcutil/silcutil.[ch].
4415 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4417 * Close log file after open. Affected file
4418 lib/silcutil/silclog.c.
4420 * Check whether sock == NULL in silc_client_send_packet and return
4421 if it is. Affected file lib/silcclient/silcclient.c.
4423 * Check rec->entry == NULL in the Irssi SILC Client before
4424 sending the channel message. Affecte file is
4425 irssi/src/silc/core/silc-servers.c.
4427 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4429 * Merged a splitted window bugfix from Irssi CVS tree. The
4430 affected file is irssi/src/fe-text/textbuffer-view.c.
4432 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
4433 It did not print nickname.
4435 * Improved the distributions system a bit.
4437 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4439 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
4440 irssi/src/fe-text/gui-window.c.
4442 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
4443 to in-active server. The affected file is
4444 irssi/src/silc/core/client_ops.c.
4446 * Resolve the client in USERS command reply if the entry does
4447 not have username resolved. The affected file is
4448 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
4449 command to WHOIS command to really resolve stuff. The USERS
4450 is not used any more in any critical section so WHOIS can
4451 be used even though it might be slower than IDENTIFY.
4453 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
4456 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4458 * Changed the protocol API a bit more consistent in the
4459 lib/silccore/silcprotocol.[ch].
4461 * Changed the following headers to ROBODoc format:
4463 lib/silccore/silcpayload.h
4464 lib/silccore/silcprotocol.h
4465 lib/silccore/silcsockconn.h
4467 All core library headers are now formatted.
4469 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4471 * Fixed a bug in Irssi SILC client; do not show that you are
4472 server/router operator if you really are not. Affected file is
4473 irssi/src/silc/core/client_ops.c.
4475 * Renamed silc_command_free_payload to silc_command_payload_free.
4476 Affected file lib/silccore/silccommand.h
4478 * Added silcmath.h to include the prototoypes of various routines
4479 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
4482 * Changed the following headers to ROBODoc format:
4484 lib/silccore/silcchannel.h
4485 lib/silccore/silccommand.h
4486 lib/silccore/silcid.h
4487 lib/silccore/silcidcache.h
4488 lib/silccore/silcmode.h
4489 lib/silccore/silcnotify.h
4490 lib/silccore/silcpacket.h
4491 lib/silcmath/silcmath.h
4493 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4495 * Added checking to the server code not to start the server if
4496 ciphers and stuff are not configured properly. Affected files
4497 silcd/serverconfig.[h] and silcd/server.c.
4499 * Changed the layout of the header files of the public interfaces
4500 in the SILC libraries. The new layout supports ROBODoc
4501 documentation tool (and some others) so that it is easy to create
4502 a library reference manual. All the other headers and source
4503 code must still follow the CodingStyle document. Also source
4504 code must not include these ROBODoc stuffs, only the headers.
4505 Furthermore, all public interface headers must now be named
4506 by using `silc' prefix, example: silcapi.h, silccipher.h.
4507 Some files were renamed due to this. All the other headers
4508 must not be used as public interfaces. I will update the
4509 CodingStyle document later. Changed following headers, so far:
4511 lib/silcclient/silcapi.h
4512 lib/silccore/silcauth.h
4513 lib/silccore/silcprivate.h
4514 lib/silccrypt/silcdh.h
4516 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4520 * Removed silc_client_packet_send_flush from the client library
4521 as it is not needed. Affected file lib/silcclient/client.[ch].
4523 * Added printing of message of unresolved authentication method
4524 to the Irssi SILC client. Added it to the module formats.
4525 Removed the same message from the client library.
4527 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4529 * Added new distribution feature, DISTLABEL. Every distribution
4530 can define own preprocessor label that can be used in the
4531 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
4532 file distributions, acconfig.h.pre and prepare.
4534 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4536 * Added Makefile.defines_int to include the actual definitions
4537 for Makefile.defines.in. Tested the new distribution system,
4538 created distributions and tested installation.
4540 * Added AWAY message printing to the Irssi SILC client. Added
4541 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
4543 * Added SCONNECT command to call the SILC's CONNECT command.
4544 Cannot use CONNECT directly since Irssi uses that internally.
4545 Affected file irssi/src/silc/core/silc-servers.c.
4547 Added ACTION local command. It is same as ME command but takes
4548 the channel as mandatory argument.
4550 Rewrote some of the Irssi's help files to suite for SILC
4553 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4555 * Added Makefile.defines[.in] that should for now on be included
4556 in all Makefile.am file in the source tree. That file includes
4557 all common compilation definitions for SILC source tree.
4559 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4561 * Minor changes to the ./prepare script to change the package
4562 name according the distribution name to the configure.in.
4564 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4566 * Created new distribution system. Added file `distributions'
4567 that defines all the distributions that can be created out of
4568 the SILC source tree. The ./prepare script now reads that
4569 file to determine how to prepare the distributions. The
4570 first argument to the ./prepare is the name of the distribution
4571 and second is the version of the distribution. If given
4572 without arguments it creates the default (toolkit) distribution
4573 with the default version (defined in ./prepare).
4575 All Makefile.am files that are subject to the distributions
4576 are now named as Makefile.am.pre. These are ./Makefile.am
4577 and lib/Makefile.am. Others may be changed later.
4579 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4581 * Added invite list, ban list, some key management and connection
4582 error message printing to module formats in the Irssi SILC client.
4584 * Added new silc_client_set_away_message to set the away message
4585 that is back to the person who sent private message. The
4586 affected file lib/silcclient/silcapi.h and the
4587 lib/silcclient/client_prvmsg.c.
4589 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4591 * Fixed the private message sending in the Irssi SILC client,
4592 added local command KEY to the Irssi SILC client.
4594 Added key management and key agreement message formats to the
4595 irssi/src/fe-common/silc/module-formats.[ch].
4597 Added USERS (alias WHO) printing, server/router operator
4598 indication and LIST command printing to the module formats.
4600 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4602 * Fixed channel joining notify handling, cumode notify handling
4603 from Irssi SILC client.
4605 * Added SILC specific module-formats to the Irssi SILC client so
4606 that SILC specific message hilighting, colors etc is possible.
4607 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4609 Added channel mode, channel user mode, actions, notices,
4610 whois and whowas printing to the the module-formats.c.
4612 * Fixed a bug in channel deletion in the server. The channel
4613 is not left to the cache even if the channel founder auth mode
4614 is set when there are no users anymore on the channel. Affected
4615 file silcd/server.c.
4617 * The silc_net_localhost now resolves the entire hostname including
4618 the domain name. Affected file lib/silcutil/silcnet.c.
4620 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4622 * Changed the ask_passphrase client operation to be ascynchronous.
4623 It has now a completion callback and a context that the
4624 application must call after it has got the passphrase from
4625 the user. Affected files lib/silcclient/silcapi.h,
4626 lib/silcclient/protocol.c, lib/silcclient/command.c and
4629 Added SilcAskPassphrase callback that the application calls
4630 to deliver the passphrase to the library.
4632 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4633 The public key verification and especially a certificate
4634 verification is asynchronous procedure.
4636 Added new SILC_SKE_STATUS_PENDING status to indicate the
4637 request is pending and a callback will be called to finalize
4640 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4641 indicate that remote end did not send its public key (or
4642 certificate), even though we require it. Added check for this
4643 condition in the SKE. This was a security bug, now fixed.
4645 Defined new SilcSKEVerifyCbCompletion callback that is called
4646 when the verification process is completed.
4648 The affected files lib/silcske/silcske_status.h and
4649 lib/silcske/silcske.[ch].
4651 * Changed the verify_public_key client operation to be async
4652 as well. Defined SilcVerifyPublicKey callback that is used to
4653 indicate the success of the public key verification process.
4655 Changed the server and client to use the new async client
4658 * Changed the Irssi SILC client's internal scheduler to be called
4659 twice as many times as it used to be. As a result the client
4660 should be a bit faster now. Affected file is
4661 irssi/src/silc/core/silc-core.c.
4663 * Added support to Irssi SILC client of asynchronous public key
4664 verification and passphrase inquiry. Affected file is
4665 irssi/src/silc/core/silc-core.c.
4667 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4669 * Do not say "You have left channel %s" in client library.
4670 Moved it to the application. Affected files are
4671 lib/silcclient/command.c and silc/client_ops.c.
4673 * Fixed silc_client_get_clients. Command context was not
4674 duplicated and was freed memory in the callback. Affected
4675 file lib/silcclient/idlist.c.
4677 * Do not say "you are now talking..." on JOIN command in the
4678 client library. The appliation must handle it.
4680 * Do not say ".. changed topic to" in command reply in the
4681 client libary. The application must handle it.
4683 * Fixed TOPIC command sending in the client library.
4685 * Fixed a memory leak in silc_client_command_free in the file
4686 lib/silcclient/command.c.
4688 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4690 * Imported a modified version of Irssi client to the source tree.
4691 The Irssi will be used to create a new client called
4692 Irssi SILC. Imported to irssi/.
4694 Added silc_core_init_finish function to the Irssi. Affected
4695 file irssi/configure.in.
4697 A lot changes in the Makefile.ams around the irssi tree.
4699 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4701 * Do not rehash if the new size is same as the old size of the
4702 hash table, in the silc_hash_table_rehash*. The affected file
4703 lib/silcutil/silchashtable.c.
4705 * Replaced hash_table_del_by_context calls from the server
4706 (when channel->user_list and client->channels) to the
4707 hash_table_del as it is sufficient and faster.
4709 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4711 * Added silc_hash_table_list, silc_hash_table_get and the
4712 SilcHashTableList structure to provide an alternative way to
4713 traverse the hash table. The affected files are
4714 lib/silcutil/silchashtable.[ch].
4716 * Changed the server's idlist routines to use the hash table
4717 routines to optimize the code.
4719 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4721 * Replaced the client entry's `channel' list and channel entry's
4722 `user_list' list to hash tables for optimized lookup. Changed
4723 the code to use the hash table interface around the code.
4724 Affected file lib/silcd/idlist.[ch].
4726 * Added `auto_rehash' boolean argument to the function
4727 silc_hash_table_alloc to indicate whether the hash table should
4728 auto-rehash when it thinks is appropriate time. It will
4729 increase the hash table size if the there is twice as much
4730 entries in the table than the size of the table, and will
4731 decrease the size if there are twice as less entries than
4732 the size of the table.
4734 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4736 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4738 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4740 * silc_idcache_purge_by_context deletes the entry now by context
4741 as it is supposed to do. Affected file lib/silccore/idcache.c.
4743 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4744 client is not anymore valid (WHOWAS givens the info) and not
4745 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4747 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4749 * Removed the `data' and `data_len' arguments from the ID Cache
4750 interfaces and added `name' argument. ID Cache does not handle
4751 anymore the binary data only a names associated with given ID.
4753 * When hashing a Client ID with silc_hash_id the entire ID is
4754 not hashed anymore, instead only the hash of the Client ID is
4755 hashed. This way we can access the Client ID from the cache
4756 with Client ID but with the hash of the ID (which is a hash of
4757 the nickname) as well without any difference in performance.
4759 Added also silc_idcache_find_by_id_one_ext to do one on one
4760 searching when we have the actual ID. Added also function
4761 silc_hash_client_id_compare. The affected files are
4762 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4764 * When hashing the name associated with a ID it is always done
4765 in lowercase. This way we can access the cache without worrying
4766 about case-sensitivity, even though, for example nicknames are
4769 * Fixed a bug in server with channel message sending. It put
4770 wrong ID type as destination ID. The affected file
4771 silcd/packet_send.c.
4773 * silc_idcache_del_by_context now deletes from all hash tables
4774 by context. Affected file lib/silccore/idcache.c.
4776 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4778 * Changed the client library to use the new ID Cache interface.
4779 Changes around the source tree.
4781 * Added silc_hash_table_rehash_ext to rehash with specific
4782 hash function. Affected file lib/silcutil/silchashtable.[ch].
4784 * Added silc_hash_string_compare to compare two strings in the
4785 hash table. Affected file lib/silcutil/silcutil.[ch].
4787 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4789 * Added new function silc_idcache_del_by_context into the
4790 lib/silccore/idcache.[ch].
4792 * Changed the server's ID list routines to use the new ID Cache
4793 interface. Changes around the source tree.
4795 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4797 * Added silc_hash_table_del[_by_context]_ext functions in to the
4798 lib/silcutil/silchashtable.[ch].
4800 Removed silc_hash_table_find_all* routines and added new
4801 silc_hash_table_find_foreach to replace them.
4803 Added silc_hash_table_replace_ext function as extended
4804 replacing function. Separated the simple hash table interface
4805 from the extended hash table interface in the file
4806 lib/silcutil/silchashtable.h.
4808 * Fixed minor bugs and changed it to use some of the new
4809 hash table functions in lib/silccore/idcache.c
4811 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4813 * Added new function silc_hash_table_find_all to return all keys
4814 in the hash table by the specified key. As the hash table is
4815 collision resistant it also makes it possible to have several
4816 duplicate keys in the hash table. This function may be used to
4817 find all of the keys from the hash.
4819 Added user_context arguments to the SilcHashFunction,
4820 SilcHashCompare and SilcHashDestructor to deliver user specified
4823 Added new fuctions silc_hash_table_find[_all]_ext to do
4824 extended lookup with specified hash and compare functions and
4825 specified user contexts.
4827 Added new function silc_hash_table_add_ext to add the key
4828 with specified hash function and user context.
4830 Added new function silc_hash_table_foreach to traverse all
4831 entrys in the hash table. Added SilcHashForeach callback
4834 Added new function silc_hash_table_del_by_context to delete
4835 the entry only if the context associated with the key matches.
4837 Affected files are lib/silcutil/silchashtable.[ch].
4839 * Removed silc_hash_[server/client/channel]_id and added just
4840 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4841 silc_hash_id_compare to compare two ID's using as the hash table
4842 comparison function. Added also silc_hash_data to hash
4843 binary data and silc_hash_data_compare to compare it.
4845 * Removed silc_idlist_find_client_by_hash as it is not needed
4846 anymore. Affected file silcd/idlist.[ch].
4848 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4849 to use internally the SilcHashTable. The new ID Cache is a lot
4850 faster than the old one. Some of the ID Cache interface was also
4851 rewritten and obsolete and stupid functions were removed.
4853 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4855 * Added entry_count field to the SilcHashTable to keep the number
4856 of the entries in the table. Implemented the function
4857 silc_hash_table_rehash. Added new function
4858 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4860 Fixed a minor bug in silc_hash_table_free.
4862 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4863 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4864 into the lib/silcutil/silcutil.[ch].
4866 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4868 * Implemented a collision resistant hash table into the
4869 lib/silcutil/silchashtable[ch]. See the header and the source
4870 for the SilcHashTable API.
4872 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4874 * Merged dotconf version 1.0.2 into lib/dotconf.
4876 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4878 * Do not compile anything in lib/silcsim/* if the SIM support
4879 is not enabled. The tree should now compile without problems
4882 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4884 * Compiled the SILC under cygwin. Compiled and tested briefly
4885 without problems. More tests needed. The SIMs didn't compile
4888 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4890 * Fixed possible crash in silc_get_username in the
4891 lib/silcutil/silcutil.c.
4893 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4895 * Fixed a va_arg in silc/client_ops.c.
4897 * Oops, RC5 routines were named AES and caused some problems
4898 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4900 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4902 * Added new SilcIDIP structure into the lib/silccore/id.h and
4903 replaced the old `ip' fields from all SILC ID's to that type.
4904 This is a step towards IPv6 support.
4906 The silc_id_get_len takes now the ID as an extra argument.
4907 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4908 both IPv4 and IPv6 based ID's.
4910 The affected files are lib/silccore/id.[ch] and other files
4911 around the tree using these routines.
4913 * Removed the ID length arguments in server from various
4914 silc_server_send_notify_* routines -> they are not needed
4917 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4919 * Fixed memory leak in silc_encode_pem_file in the file
4920 lib/silcutil/silcutil.c.
4922 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4924 * Check minor version as well in the SKE. Affected files are
4925 silcd/protocol.c and lib/silcclient/protocol.c.
4927 * Added --identifier option to the server so that an identifier
4928 can be when creating the public key for the server. Affected
4929 file is silcd/silcd.c.
4931 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4932 lib/silccrypt/silcpkcs.c.
4934 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4936 * Register default ciphers and stuff when using -C option with
4937 the server. Affected file sildc/silcd.c.
4939 * Put back the servers public key filename format, it is better
4940 than the new one. For now, the client keys are saved with the
4941 new filename format. The affected file silc/client_ops.c.
4943 * Implemented the Cipher API for the rest of the ciphers that
4944 did not implement it or implemented it the wrong way.
4946 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4948 * Register default ciphers and stuff when using the -S option
4949 in the client. Affected file silc/silc.c. Same also when
4950 creating new key pair with -C option.
4952 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4954 * Fixed the silc_verify_public_key client operation function to
4955 save the public keys differently. The fingerprint is now
4956 used as filename and not the hostname. This way also the
4957 client keys are saved uniquely and not with hostnames. The
4958 affected file is silc/client_ops.c.
4960 * Trimmed the silc_hash_fingerprint function to remove extra
4961 whitespaces from the end of the fingerprint. The affected
4962 file is lib/silccrypt/silchash.c.
4966 * Added silc_cipher_register_default function to register all
4967 default ciphers. It can be used when configuration files
4968 does not exist and the application does not want any specific
4969 ciphers in any specific order.
4971 The SilcDList is now used as silc_cipher_list dynamically
4972 allocated cipher list. Removed the static list all together
4973 and now all ciphers must be allocated to the dynamic list.
4974 The silc_cipher_alloc routine was changed to check only the
4977 All silc_cipher_* routines that used to return int returns
4980 The affected files lib/silccrypt/silccrypt.[ch].
4982 * The same thing was done to silc_hash_* as for silc_cipher_*
4983 routines. Affected files lib/silccrypt/silchash.[ch].
4985 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4986 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4987 Added also silc_pkcs_[un]register[_default] functions.
4988 Removed the data_context from the PKCS API.
4990 * Added silc_hmac_register_default function to register default
4991 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4992 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4993 to unregister all hmacs at once.
4995 * Register the default ciphers, hash functions, PKCSs and HMACs
4996 if client's configuration file does not exist. The affected
4999 * The client did not load the hash functions from the SIM
5000 modules at all. Added support for this. Affected file is
5001 silc/clientconfig.c.
5003 * When decoding public key with silc_pkcs_public_key_decode, check
5004 the supported algorithm only if PKCS are registered. Affected
5005 file lib/silccrypt/silcpkcs.c. The same was done with the
5006 silc_pkcs_private_key_decode.
5008 * Fixed the SILC List routines to keep the list always in order.
5009 It used to change the list's order when traversing the list but
5010 not it preserves the order. Affected file lib/trq/silclist.h.
5012 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5014 * Added the client library to use the SilcSocketConnection's
5015 reference counter (by silc_socket_dup) to prevent the bug that
5016 the socket object may be freed underneath async operation.
5018 * The name resolv library checking fixes in the configure.in.pre.
5021 * Created new version of the protocol drafts for future
5022 development. The -03 drafts are the ones that will be changed
5023 in the trunk now and the -02 will remain as they are.
5025 * Send list of CUMODE notifys to the router when announcing
5026 the channel users to the router. Affected file silcd/server.c.
5027 If the router receiving channel founder CUMODE for a channel
5028 that already has channel founder it will send CUMODE notify
5029 to the sender to remove the channel founder rights from the
5030 announced client. Affected file silcd/packet_receive.c.
5032 * The CUMODE notify may now use Server ID as well as the entity
5033 who changes the mode. Updated protocool specs.
5035 * Updated INSTALL and README files.
5037 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5039 * New web pages in the http://silc.pspt.fi. The pages was
5044 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5046 * Implemented the [DenyConnectin] config section in the server.
5047 Added silc_server_config_denied_conn to check whether incoming
5048 connection is denied. Affected file silcd/serverconfig.[ch].
5050 * Do not check the ports when checking the incoming configuration
5051 data if the port is 0, meaning any. Affected file is
5052 silcd/serverconfig.c.
5054 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5056 * Fixed buffer overflow in silc_string_compare in the file
5057 lib/silcutil/silcutil.c.
5059 * Fixed double free in silc_server_command_leave in the file
5062 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5064 * Fixed the version checking in the server. Affected file is
5067 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5069 * Fixed the configuration data fetching when accepting new
5070 connections in the server. Affected file silcd/server.c.
5072 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5074 * Added `sender_entry' argument to the function
5075 silc_server_packet_relay_to_channel so that we can check
5076 whether some destination actually belongs to the same route
5077 the sender belongs (ie, we must not resend the packet to the
5078 sender). Affected file silcd/packet_send.[ch].
5080 * Added `servername' field to the SilcClientEntry in the server
5081 to hold the name of the server where client is from. Affected
5082 file is silcd/idlist.h.
5084 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5086 * Moved the channel message encrypting in the router betwen
5087 router connections from silc_server_channel_message to the
5088 silc_server_packet_relay_to_channel since we want to check
5089 whether we have anybody channel before encrypting anything.
5090 Affected files silcd/packet_[receive/send].c.
5092 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5094 * Fixed the [AdminConnection] server config section to support
5095 multiple entries. Affected file silcd/serverconfig.c.
5097 * Added support into the server to check the validity of the
5098 incoming connection before executing any KE or authentication
5101 * The connection configuration is now saved to the KE and
5102 connection auth protocol contexts and not fetched anymore in
5103 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
5105 * The local hosts listenning address and port is also resolved
5106 now when starting the server. We want to have the socket object
5107 to include the real address and port for the listener. Added
5108 new function silc_net_check_local_by_sock into the files
5109 lib/silcutil/silcnet.[ch].
5111 * Fixed a broadcast bug in server -> do not broadcast if we
5114 * Fixed a routing bug. Do not route broadcast packets ever.
5115 Broadcast packets must be processed always and not routed since
5116 they may be destined to some other host than yourself and thus
5117 would get routed without no good reason. Affected file is
5120 * Added function silc_server_config_is_primary_route to check
5121 whether primary router connection has been configured (a router
5122 configuration that we are initiating). If there is not, we
5123 will assume that there is only two routers in the SILC network
5124 and we will use the incoming router connection as our primary
5125 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
5127 * Changed the order of the broadcasting. Broadcast _after_ the
5128 packet has been processed not before. Affected file is
5131 * Fixed a [ClientConnection] parsing bug. The port was never
5132 parsed correctly thus resulting to port 0. Affected file
5133 silcd/serverconfig.c.
5135 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
5136 argument and did not set the broadcast packet flag. Affected
5137 file silcd/packet_send.c. Fixed same bug in the function
5138 silc_server_send_notify as well.
5140 * If we receive NEW_ID packet for our own ID in the server, ignore
5143 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5147 * Removed the nickname from the Private Message Payload.
5148 Updated the code and the protocol specs.
5150 * Updated protocol specs for submitting to the IETF.
5152 * Tweaked the Random Number Generator a bit. Affected file
5153 lib/silccrypt/silcrng.c. Exported a new function
5154 silc_rng_[global]_add_noise which can be used to add more
5157 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5159 * Do not parse packets with different timeout when protocol
5160 is active -> may cause problem with rekey. Affected file
5163 * When server receives signoff notify it must not create
5164 new channel key if the client is on any channels since the
5165 sender of the signoff notify will create it.
5167 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5169 * Added printing of error messages during SKE protocol from the
5170 failure packet sent by server during SKE. Affected file
5173 * Removed the client's failure_callback handling with timeout
5174 and handle it immediately when received.
5176 * The SKE library returned wrong type in SUCCESS and FAILURE
5177 packets. They must be 32 bit MSB not 16 bit MSB.
5179 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5181 * Ok, rewrote the logic of the re-key and now it seems to work.
5182 I tested it on high traffic with frequent re-keys without
5183 problems. Added hmac_receive (and renamed hmac to hmac_send)
5184 in SilcClientConnection in lib/silcclient/client.h and
5185 in SilcIDListData in silcd/idlist.h. Also, removed the
5186 SilcPacketParserContext's cipher and hmac fields as they are
5187 not needed anymore and actually caused some problems when
5188 the ciphers and hmac's changed underneath the packet parser.
5190 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5192 * If re-key protocol is active then process the incoming packets
5193 synchronously since we must assure that icoming packets encrypted
5194 with the old key is processed before the new keys is set to
5195 use. This is true other packets than for REKEY packets.
5196 Affected file silcd/server.c. The same was done to client library
5197 as well, affected file lib/silcclient/client.c.
5199 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5201 * Fixed bug in client and server to accept the force send if
5202 the packet is send from silc_[server/client]_packet_process
5203 function. Otherwise the packets are never delivered, oops.
5205 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5207 * Disable force sending of packets when REKEY protocol is active.
5208 We must assure that no packet is sent directly when rekey is
5209 performed. All packets must be sent through packet queue.
5210 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
5211 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
5212 function is silc_[server/client]_packet_send_real to check
5215 * Replaced the SIM paths from example config files to
5216 /usr/local/modules. Also, make install creates now
5217 /usr/local/silc/logs directory to hold all the SILC server
5220 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5222 * Made the configure.in.pre work on Solaris. Patch by salo.

5231 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5233 * When MAC computation fails the silc_packet_decrypt returned 0
5234 even though it was supposed to return -1. Fixed this. The
5235 affected file is lib/silccore/silcpacket.c.
5237 * Do not replace the config files in /etc/silc (in make install)
5238 if they already exist. Affected file ./Makefile.am.
5240 * Do not send re-key packets immediately but through packet queue.
5241 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
5243 * Changed silc_net_check_host_by_sock to return FALSE if the
5244 IP/DNS could not be resolved. Though, it returns the IP address
5245 now even if it could not resolve it (but returns also FALSE).
5246 Affected file lib/silcutil/silcnet.[ch].
5248 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5250 * Added silc_pkcs_decode_identifier to decode the public key's
5251 identifier. Affected file lib/silccrypt/silpkcs.[ch].
5252 Added also silc_pkcs_free_identifier. Added also new context
5253 SilcPublicKeyIdentifier.
5255 * Added -S option to the silc client. It is used to dump the
5256 contents of the specified public key file.
5258 * Changed the PKCS api to return the public key length when
5259 setting the public key.
5261 * Fixed a fatal bug in the public and private key file loading.
5262 Affected file lib/silccrypt/silcpkcs.c.
5264 * Execute the packet parsing for client with zero (0) timeout
5265 if the protocol is active. Affected file silcd/server.c.
5267 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5269 * Made the key generation options to the silcd program. Added
5270 -C option, equivalent to client's option.
5272 * Added new [ServerKeys] config section to the server. It
5273 configures the server's public and private key.
5275 * Defined generic Public Key Payload into the protocol
5276 specification to send specific type of public keys and
5279 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
5280 public key or certificate.
5282 * Implemented the GETKEY command to the server and to the
5283 client library and on user interface.
5285 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5287 * Made preliminary `make install' work.
5289 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5291 * Added SilcServerRekey context into silcd/idlist.h.
5293 * Added the PFS support as defined in the specification to the
5294 SKE protocol. Affected files lib/silcske/*.c.
5296 * Added `ske_group' field to the SilcServerRekey context to hold
5297 the number of the SKE group that is used with PFS in re-key.
5298 Affected file silcd/idlist.h.
5300 * Added PFS re-key support to the server. Affected file is
5303 * Added silc_protocol_cancel to cancel execution of the next
5304 state of the protocol. Affected file is
5305 lib/silccore/silcprotocol.[ch].
5307 * Added the re-key support with and without PFS to the client
5308 library. Re-key is performed once in an hour, by default.
5310 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
5311 Added silc_client_rekey_callback and silc_client_rekey_final.
5312 Affected files are lib/silcclient/protocol.[ch] and
5313 lib/silcclient/client.[ch].
5315 * Removed the `hmac_key' and `hmac_key_len' fields from the
5316 SilcClientConnection structure; not needed. Affected file is
5317 lib/silcclient/client.h.
5321 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5323 * Do not ask whether user wants to use the negotiated private key
5324 for private messages, just use it. Affected file is
5325 silc/local_command.c.
5327 * Added `send_enc_key' and `enc_key_len' fields to the
5328 SilcIDListData structure since they are needed in the re-key
5329 phase. Affected file is silcd/idlist.[ch].
5331 * Implemented the simple re-key protocol into the server.
5332 Affected files silcd/server.c and silcd/protocol.[ch]. The
5333 re-key will be performed once in an hour, by default.
5335 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
5336 Added silc_server_rekey, silc_server_rekey_callback and
5337 silc_server_rekey_final.
5339 * Removed Tunneled flag from the protocol. Updated the code
5340 and the specifications.
5342 * Adde `pfs' field to the SilcIDListData to indicate whether
5343 the PFS is to be performed in the re-key. Affected file is
5346 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5348 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
5349 int64 of at least the xintXX size. If void * is less that 4
5350 bytes uint32 * will be used. Defined bool as boolean.
5352 * Changed _ALL_ unsigned long and unsigned int to uint32,
5353 unsgined short to uint16 in the source tree.
5355 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
5356 not handle clients that has entry->data.registered == FALSE.
5357 They are not in the network anymore. Affected file is
5360 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5362 * Implemented the sending of the SERVER_SIGNOFF notify in the
5363 server. Affected file is silcd/server.c.
5365 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
5366 Added also silc_notify_payload_encode_args into the
5367 lib/silccore/silcnotify.[ch].
5369 * Implemented ther SERVER_SIGNOFF notify handling in the server.
5370 Affected file silcd/packet_receive.c.
5372 * Implemented the SERVER_SIGNOFF notify handling in the client
5373 library. Affected file lib/silcclient/client_notify.c. Also,
5374 implemnted the printing of the SERVER_SIGNOFF info to the
5375 application. Affected file silc/client_ops.c.
5377 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
5378 if the deleting was successful. Affected file silcd/idlist.[ch].
5380 * Added support for public key authentication in the connection
5381 authentication protocol in the client library. Affected file
5382 lib/silcclient/protocol.c.
5384 * Changed the server's silc_idlist_get_clients_by_* interface
5385 to support already allocated array so that new entries may be
5386 added to pre-allocated array. Affected file silcd/idlist.[ch].
5387 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
5388 and command replies.
5390 * All command reply functions in the server now calls the
5391 pending command callback even if error occured. This way the
5392 error will be delivered to the client as well. Affected files
5393 silcd/command.c and silcd/command_reply.c.
5395 * Fixed INFO command to return local server's info if no server
5396 was provided. Affected file lib/silcclient/command.c.
5398 * Removed RESTART command for good. Updated the code and the
5401 * Rewrote parts of the task system. It is a bit simpler now.
5402 Removed unsued task priorities. The affected files are
5403 lib/silcutil/silctask.[ch].
5405 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5407 * Moved the USERS printing from the library to the application.
5408 Affected files lib/silcclient/command.c and silc/client_ops.c.
5410 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5414 * Added channel key re-key support. The re-key is perfomed
5415 only by the router and is done once in an hour. Added `rekey'
5416 field to the SilcChannelEntry in the server. Affected files
5417 silcd/server.c and silcd/idlist.h.
5419 * Added silc_task_unregister_by_context into the file
5420 lib/silcutil/silctask.[ch].
5422 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5424 * Added SILC_UMODE_GONE mode to indicate when the client is not
5425 present in the SILC network. Added also support to the local
5426 command AWAY that will set this mode. Added support of showing
5427 "xxx is gone" in WHOIS command. The USERS command shows the
5428 gone status as well.
5430 * Fixed setting server and router operator privileges in the
5431 server's UMODE command. Affected file silcd/command.c.
5433 * Merged the SKE KE1 and KE2 payloads into one payload. The
5434 new KE payload is equivalent to the old KE2 payload.
5436 Cleaned up the SKE Start Payload parsing. It now uses the
5437 simple buffer unformatting to do the parsing. A lot faster
5440 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
5441 to the SKE that is used to indicate whether both of the SKE
5442 parties should perform authentication. By default only the
5443 responder performs authentication. By setting this flag also
5444 the initiator must do authentication. By default it is unset
5445 since in normal SKE case, client to server connection, only
5446 the responder should do authentication. When doing SKE between
5447 two clients both should perform authentication. Updated the
5448 code and the protocol specs.
5450 * A little fix to IDENTIFY command in the server. Search the
5451 client first by hash not nickname. Affected file is
5454 * Fixed the silc_client_close_connection to support closing
5455 the client to client connections wihtout deleting too much
5456 data. Affected file lib/silcclient/client.c.
5458 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
5459 are received if protocol used to be active but is not anymore
5460 the application would crash due to NULL pointer dereference.
5461 Affected files silcd/server.c and lib/silcclient/client.c.
5463 * Added `hash' field to the SilcClientConnection to include
5464 the hash function negotiated in the SKE protocol.
5466 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
5467 to set the channel founder authentication data. A client can
5468 claim the founder rights later by providing the authentication
5469 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
5470 This way the channel founder can regain the channel founder
5471 privileges even it is left the channel. This works only on
5472 local server and the client must be connected to the same
5473 server to be able to regain the founder rights. Updated the
5474 protocol specs accordingly.
5476 Added support to the CMODE command in the client to set the
5477 founder auth data. Read the README to see how to set it.
5479 Added support to the CUMODE command to claim the founder
5480 rights. Read the README to see how to do it.
5482 Added support for the founder authentication to the Channel
5483 Entry in the server. Affected file silcd/idlist.h.
5485 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
5486 server's CMODE command. Affected file silcd/command.c.
5488 * Added the following new functions into lib/silccore/silcauth.[ch]:
5489 silc_auth_get_method and silc_auth_get_data.
5491 * The server now saves the remote hosts public key to the
5492 SilcIDListData pointer. Affected file silcd/protocol.c.
5494 * The normal server now does not remove the channel entry from
5495 the cache if the founder authentication data is set. It used
5496 to remove it if the founder was the last one on the channel on
5497 the server and left the channel. The auth data is saved and
5498 if the channel is re-joined later the old entry is used with
5499 the old auth data. Affected files silcd/command_reply.c and
5502 * Removed the `pkcs' field from the SilcIDListData structure
5503 in the server; it is not used. Affected file silcd/idlist.h.
5505 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5507 * Fixed packet processing on slow links. Partial packets were
5508 never re-processed because the incoming data buffer was cleared
5509 by the application. Application must not directly clear the
5510 sock->inbuf, the packet processing routines handle it. Fixed
5511 this in client library and in server.
5513 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5515 * Fixed the WHOIS and IDENTIFY send reply function to really
5516 check whether to send list or just one entry. Affected file
5519 * Cleaned up the LEAVE command's channel key distribution. The
5520 affected file silcd/command.c.
5522 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
5523 can enforce the channel mode as well. In that case the ID
5524 includes the ID of the server. The code now enforces the
5525 mode change if the router have different mode than the server.
5527 * The notify client operation with CMODE_CHANGE notify can now
5528 return NULL client_entry pointer if the CMODE was not changed
5529 by client. Application must check for this.
5531 * Added <Server ID> argument to INFO command to support server
5532 info fetching by Server ID.
5534 * Added silc_server_announce_get_channel_users to get assembled
5535 packets of channel users of the specified channel. Affected
5536 file silcd/server.[ch].
5538 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
5539 was freed underneath the ID Cache.
5541 * Re-announce clients when the server received CHANNEL_CHANGE
5542 notify from the router. Affected file silcd/packet_send.c.
5544 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5546 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
5547 crashed since it did not handle the fact that there is no cipher
5548 called "3" and didn't check the error condition. Now fixed.
5550 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
5551 flag. It can be used to send message requests.
5553 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5555 * Implemented the RESTART command in the client.
5557 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
5558 notice type messages. Added notice printing to the user
5561 * The channel keys are not re-generated if the channel's mode
5562 is PRIVKEY, ie private key on the channel exists. Affected
5563 files silcd/server.c and silcd/command.c.
5565 * Fixed a little bug in channel message delivery when channel
5566 private keys are set in the server. Affected file is
5567 silcd/packet_send.c.
5569 * Changed the setting on channel->on_channel = TRUE from the
5570 silc_client_save_channel_key to the JOIN command reply. The
5571 key payload is not received if the private channel key is set.
5572 Affected file lib/silcclient/command_reply.c and the
5573 lib/silcclient/client_channel.c.
5575 * When the CMODE_CHANGE notify is sent and the channel private
5576 key mode is removed the channel key must be re-generated in
5577 other cells as well. Added this support for the router in the
5578 silcd/packet_receive.c.
5580 * Added new local command NOTICE to send notice message on
5581 channel. Affected file silc/local_command.[ch].
5583 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5585 * Added new local command ME to the client. It is used to send
5586 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
5587 some action. Affected file silc/local_command.[ch].
5589 * Changed channel_message and private_message client operations
5590 to deliver the message flags to the application. Added also
5591 the `flags' arguments to the silc_client_send_channel_message
5592 and silc_client_send_private_message functions. Affected file
5595 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5597 * Redefined the Private Message Payload to support private message
5598 keys and to support the new private message flags. Updated
5599 the protocol specs. Flags makes it possible to have for example
5600 CTCP style messages.
5602 * Added new type SilcPrivateMessagePayload and defined an API
5603 for it in the lib/silcclient/silcprivate.[ch].
5605 * Tested private message private keys successfully. Tested the
5606 private message key set, unset and list commands with the new
5609 * Redefined the Channel Message Payload to include the channel
5610 message flags (equal with private message flags) to support
5611 for example CTCP style messages.
5613 * Defined some of the message (for channel and private message)
5614 flags. Updated the protocol specs and added the flags to the
5615 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5617 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5619 * Added SilcKeyAgreementStatus type to the key agreement routines
5620 to indicate the current status and error if one occured.
5621 The status types are defined in the lib/silcclient/silcapi.h.
5623 * Added new local command KEY that is used to set and unset private
5624 keys for channels, set and unset private keys for private messages
5625 with remote clients and to send key agreement requests and
5626 negotiate the key agreement protocol with remote client. The
5627 key agreement is supported only to negotiate private message keys,
5628 it currently cannot be used to negotiate private keys for channels,
5629 as it is not convenient for that purpose.
5631 * Fixed a minor pending callback setting bug in the function
5632 silc_client_get_client_by_id_resolve, now the function works.
5633 Affected file lib/silcclient/idlist.c.
5635 * Added function silc_net_get_local_port to get local bound
5636 port by socket. Added to lib/silcutil/silcnet.[ch].
5638 * Added `sockets' and `sockets_count' fields to the SilcClient
5639 object. They hold the sockets of the listenning sockets in
5640 the client. Listenning sockets may be for example the key
5641 agreement server. Affected file lib/silcclient/client.[ch].
5642 Added functions the silc_client_add_socket and the
5643 silc_client_del_socket. They are exported to the application
5646 * Added ~./silc/clientkeys to support other client's public keys.
5648 * Renamed verify_server_key client operation to verify_public_key
5649 and added one argument to indicate the type of the connection
5650 (server, client etc.).
5652 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5654 * Added silc_server_connection_auth_request to handle the
5655 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5656 silcd/packet_receive.[ch].
5658 * Added silc_server_send_connection_auth_request into the
5659 silcd/packet_send.c to send the connection auth request packet.
5661 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5664 * Fixed the public key authentication in responder side in the
5665 server. The `auth_data' pointer includes the SilcPublicKey
5666 not the path to the public key. Affected file silcd/protocol.c.
5668 * Implemented the public key authentication in the initiator side
5669 in the server. Affected file silcd/protocol.c.
5671 * Removed the [RedirectClient] config section from the server
5672 configuration. Is not needed and I don't want to implement it.
5674 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5676 * Cleaned up the CMODE command in the server. It now works
5677 correctly and supports all the modes defined in the protocol.
5678 Affected file is silcd/command.c.
5680 * Added `hmac_name' field to the SilcChannelEntry in the server
5681 to hold the default HMAC of the channel. It can be set when
5682 creating the channel (with JOIN command). Affected files
5685 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5686 type to indicate the change of the current cipher and hmac
5687 on the channel. Client can safely ignore the <cipher> argument
5688 (if it chooses to do so) since the CHANNEL_KEY packet will
5689 force the channel key change anyway. The <hmac> argument is
5690 important since the client is responsible of setting the new
5691 HMAC and the hmac key into use.
5693 * Fixed the CMODE command in the client library as well.
5695 * Tested CMODE command in router environment successfully.
5697 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5699 * Show the version of the remote client (or server) when connecting
5700 to the server. It is logged to the log file. Affected file
5701 is silcd/protocol.c.
5703 * Fixed the KILLED notify handling in the client library. The
5704 client must be removed from all channels when receiving the
5707 Also, do not remove the client entry when giving the KILL
5708 command but when the KILLED notify is received.
5710 * Removed silc_idlist_find_client_by_nickname from the server.
5711 Not needed anymore. Affected files silcd/idlist.[ch].
5713 * Implemented the CHANNEL_CHANGE notify type handling to the
5714 server. Affected file silcd/server.c.
5718 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5720 * Added silc_server_send_notify_invite to send the INVITE
5721 notify between routers.
5723 * Implemented the INVITE command correctly to the server.
5725 * Implemented the INVITE notify type handling in the server.
5727 * Implemented the INVITE command to the client library and on the
5730 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5732 * Added function silc_server_get_client_resolve to find the
5733 client entry by ID from all ID lists and then resolve it
5734 (using WHOIS) if it cannot be found. Affected file is
5737 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5739 * Implemented the BAN command to the client library.
5741 * The JOIN command in the server now checks the invite list
5744 * Changed the silc_command_reply_payload_encode_va and the
5745 silc_command_payload_encode_va to support that if argument is
5746 NULL it ignores and checks the next argument. Affected file
5747 lib/silccore/silccommand.c.
5749 * Added silc_server_send_notify_ban to send the BAN notify
5750 type between routers.
5752 * Chaned the silc_notify_payload_encode to support that if
5753 argument is NULL it ignores and checks the next argument.
5754 Affected file lib/silccore/silcnotify.c.
5756 * Tested ban lists in router environment successfully.
5758 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5760 * Implemented BAN command to the server, in silcd/command.[ch].
5762 * Removed the BAN and INVITE_LIST modes from the CMODE command
5765 * Added function silc_string_match to regex match two strings.
5766 Affected files lib/silcutil/silcutil.[ch].
5768 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5770 * Redefined parts of the SilcChannelEntry in the server to support
5771 the new ban and invite lists.
5773 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5775 * Redefined the INVITE command. The same command can be used to
5776 invite individuals to the channel but also to manage the invite
5777 list of the channel (to add to and remove from the invite list).
5778 Updated the protocol specs.
5780 * Added new command SILC_COMMAND_BAN that can be used to manage
5781 the ban list of the channel. Updated the protocol specs.
5783 * Removed the channel modes: the SILC_CMODE_BAN and the
5784 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5785 in the CMODE command. The equivalent features are now available
5786 using INVITE and BAN commands. Updated the protocol specs.
5788 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5789 in the network about change in the current ban list. The notify
5790 type is not used by the client.
5792 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5793 support the invite lists.
5795 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5797 * Added new function silc_string_regexify that converts string
5798 including wildcard characters into regex string that can
5799 be used by the GNU regex library. Added into the file
5800 lib/silcutil/silcutil.[ch].
5802 Added silc_string_regex_combine to combine to regex strings
5803 into one so that they can be used as one regex string by
5804 the GNU regex library. Added into the file
5805 lib/silcutil/silcutil.[ch].
5807 Added silc_string_regex_match to match two strings. It returns
5808 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5810 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5812 * Imported GNU regex to the soruce tree into lib/contrib.
5813 Fixed some compiler warning from the regex.c.
5815 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5817 * Fixed MOTD command in the server to work in router environment.
5819 * Fixed the MOTD command in the client library to support
5820 the server argument in the command.
5822 * Added `nickname_len' argument to the silc_idlist_add_client
5823 in the server, as the `nickname' argument may be binary data
5826 * Added silc_idlist_get_channels to return all channels from
5829 * Implemented LIST command to the server. Affected file is
5832 * Implemented the LIST command to the client library and on the
5835 * Added [<user count>] argument to the LIST command reply.
5836 With private channels the user count is not shown.
5838 * Updated TODO and README.
5840 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5842 * The client entry's data.registered must be TRUE even with
5843 global client entry on global client list. The data.registered
5844 is used to check whether the client is anymore in the network,
5845 for example with WHOWAS command so it must be valid.
5847 * Fixed the WHOWAS command in the server. It now actually works
5848 in router environment. Added function into silcd/command_reply.c
5849 silc_server_command_reply_whowas_save.
5851 * Added silc_idlist_purge function to the silcd/idlist.c
5852 to periodically purge the ID Cache.
5854 * Fixed INFO command in the server. It works now in router
5855 environment. Added <server name> argument to the INFO command
5856 reply. Updated the protocol specs.
5858 * Fixed minor bug in silc_idcache_purge to not purge if the
5859 expire value is zero.
5861 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5862 they were buggy because of the WHOWAS information.
5864 * Fixed local command MSG to handle the async resolving of
5865 the remote client properly. It used to fail the first MSG.
5866 Affected file silc/local_command.c.
5868 * Added `data_len' field to SilcIDCache context.
5870 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5872 * Update TODO. Todo in commands in the server.
5874 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5876 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5877 used by routers as broadcast packet to inform other routers
5878 about the changed user mode.
5880 Implemented the notify handling in the server. Affected file is
5881 silcd/packet_receive.c. Added the function
5882 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5884 * Added new generic Channel Payload and deprecated the New Channel
5885 Payload. The New Channel Payload is now the generic Channel
5888 * Added new argument `mode' to the silc_server_send_new_channel
5889 as it is required in the Channel Payload now.
5891 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5892 and created a new and real SilChannelPayload to represent the
5893 new generic Channel Payload. Implemented the encode/decode
5894 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5896 * Added silc_server_get_client_channel_list to return the list
5897 of channels the client has joined for WHOIS command reply.
5898 Affected file silcd/server.[ch].
5900 * Implemented the channel list sending in the WHOIS command reply
5901 in server and in the client.
5903 Implemented the channel list displaying on the user interface
5904 as well. Affected file silc/client_ops.c.
5906 * Added silc_channel_payload_parse_list to parse list of Channel
5907 Payloads. It returns SilcDList list of SilcChannelPayloads.
5908 Client for example can use this function to parse the list of
5909 channels it receives in the WHOIS command reply. The caller
5910 must free the list by calling silc_channel_payload_list_free.
5911 Affected files lib/silccore/silcchannel.[ch].
5913 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5915 * Added one new argument <user mode> to the WHOIS command reply
5916 to return the mode of the user in SILC. Updated the protocol
5919 Implemented it to the server and client.
5921 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5923 * Fixed the mode printing on the user interface on joining.
5924 Affected file silc/client_ops.c.
5926 * Implemented the UMODE command and user modes in general to the
5927 client library and to the user interface.
5929 * Implemented the UMODE command to the server.
5931 * The server now sends UNKNOWN_COMMAND error status if client sends
5932 unknown command. Affected file silcd/command.c.
5934 * All server commands now handle the command identifier the right
5935 way when sending the command reply to the client. The client can
5936 use to identify the command replies with the identifier.
5938 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5940 * Added silc_server_get_client_route to resolve the route to
5941 the client indicated by the client ID. Affected file is
5944 * Added silc_server_relay_packet as general function to relay
5945 packet to arbitrary destination. This deprecates functions
5946 like _send_private_message_key, _relay_notify etc. Affected
5947 file is silcd/packet_send.[ch].
5949 Removed silc_server_send_key_agreement,
5950 silc_server_send_private_message_key and
5951 silc_server_packet_relay_notify functions from the file
5952 silcd/packet_send.[ch].
5956 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5957 server. Affected file silcd/packet_receive.[ch].
5959 * Implemented the KILL command to the client. Implemented the
5960 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5961 Affected files lib/silcclient/command[_reply].c and
5962 lib/silcclient/client_notify.c. Implemented the KILL notify
5963 printing in the user inteface.
5965 * Fixed a lot silc_parse_nick memory leaks from the client
5966 library in the file lib/silcclient/command.c.
5968 * Changed the silc_server_send_notify_on_channels's `sender'
5969 argument from SilcSocketConnection to SilcClientEntry to
5970 check the sender as entry and not as connection object and not
5971 to send to the client provided as argument. The affected file
5972 is silcd/packet_send.[ch].
5974 * The notify packets that are destined directly to the client used
5975 to not to be processed by the server. Now changed that and the
5976 server processes all notify packets. After relaying the packet
5977 to the client the notify packet is processed in the server.
5979 * The silc_server_free_client_data now checks whether there is
5980 pending outgoing traffic for the client and purges the data to
5981 the network before removing the client entry.
5983 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5985 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5986 an client is killed from the SILC Network. Updated the protocol
5989 Added new function silc_server_send_notify_killed to the
5990 silcd/packet_send.[ch].
5992 * Added function silc_server_packet_relay_notify to relay notify
5993 packets that are destined directly to a client. In this case
5994 the server does not process the notify packets but merely relays
5995 it to the client. Affected file silcd/packet_send.[ch].
5997 Added also silc_server_packet_process_relay_notify to check
5998 whereto relay the notify. Affected file is
5999 silcd/packet_receive.[ch].
6001 * Implemented the KILL command to the server.
6005 * Added the backup schema desgined last fall to the protocol
6006 specs for everyone to see. The specification is in the
6007 *-spec-xx.txt draft and the packet type definitions for the
6008 backup routers is in *-pp-xx.txt draft. Thusly, added also
6009 new packet type SILC_PACKET_CELL_ROUTERS.
6011 * A big security problem in the implementation discovered. The
6012 signoff of an client did not cause new channel key generation
6013 which it of course should've done. The channel keys must be
6014 always re-generated when client leaves (or signoffs) the channel.
6015 The silc_server_remove_from_channels funtion now handles
6016 the channel key re-generation.
6018 * Added `sender' argument to the silc_server_send_notify_on_channels
6019 to not to send the client provided as argument. Affected file
6020 silcd/packet_send.[ch].
6022 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6024 * Implemented OPER and SILCOPER commands into the server and
6027 * Added silc_auth_verify and silc_auth_verify_data to verify
6028 the authentication directly from the authentication payload.
6029 It supports verifying both passphrase and public key based
6030 authentication. Affected file lib/silccore/silcauth.[ch].
6032 * Added `hash' field to the SilcIDListData structure. It is the
6033 hash negotiated in the SKE protocol. Affected file is
6036 * Slight redesigning of the SilcAuthPayload handling routines.
6037 Do not send SilcPKCS but SilcPublicKey as argument.
6039 * Implemented the public key authentication support to the
6040 serverconfig. The public key is loaded from the provided path
6041 and saved as authentication data to void * pointer. Thus,
6042 changed the unsigned char *auth_data to void *auth_data;
6044 * Fixed SHUTDOWN command to send the reply before the server
6045 is shutdown. :) Affected file silcd/command.c.
6047 * Fixed fatal bug in CONNECT command. The hostname was invalid
6048 memory and server crashed. Affected file silcd/command.c.
6050 * Fixed fatal bug in CLOSE command. The server_entry became
6051 invalid but was referenced later in the command. Affected file
6054 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6056 * Fixed fatal bug in failure packet handling. Server ignored
6057 the failure and thus crashed when it came.
6061 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6063 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
6064 that the command may be executed only once in (about) 2 seconds.
6065 The old SILC_CF_LAG flag is same but allows command bursts up
6066 to five before limiting.
6068 Added the support for CF_LAG and CF_LAG_STRICT flags to the
6069 server code. Various commands now includes the CF_LAG_STRICT
6070 flag to disallow any kind of miss-use of the command.
6072 * Fixed the silc_buffer_unformat to not to allocate any data
6073 if the length of the data is zero. It used to allocate the
6074 length + 1. Affected file lib/silcutil/silcbuffmt.c.
6076 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6078 * Changed the format of AdminConnection configuration section
6079 in the server. Added username of the admin to the format.
6080 Affected files silcd/serverconfig.[ch].
6082 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
6083 to return admin configuration data by host, username and/or
6086 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6088 * Implemented WHOWAS command to the server. Added the functions:
6090 silc_server_command_whowas_parse,
6091 silc_server_command_whowas_send_reply,
6092 silc_server_command_whowas_from_client and
6093 silc_server_command_whowas_from_server
6095 * Added <Client ID> argument to the WHOWAS command reply. Updated
6096 the protocol specs accordingly.
6098 * Implemented WHOWAS command and command_reply to the client
6101 Implemented the WHOWAS printing on the user interface.
6103 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6105 * Added new argument to the WHOWAS command reply, the real name.
6106 It is an optional argument. Updated the protocol specs.
6108 * Added SilcIDCacheDestructor callback that is registered when
6109 the SilcIDCache is allocated. The callback is called when
6110 an cache entry in the ID Cache expires, or is purged from the
6111 cache. Added into lib/silccore/idcache.[ch].
6113 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
6114 to destruct the client entries when the cache entry expires.
6115 Other ID Cache's in server and in the client library ignores
6118 * If the ID Cache entry's `expire' field is zero then the entry
6119 never expires. Added boolean `expire' argument to the
6120 silc_idcache_add function in the lib/silccore/idcache.[ch].
6121 If it is TRUE the default expiry value is used.
6123 * Added silc_server_free_client_data_timeout that is registered
6124 when client disconnects. By default for 5 minutes we preserve
6125 the client entry for history - for WHOWAS command.
6127 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6129 * Added support to the server to enforce that commands are not
6130 executed more than once in 2 seconds. If server receives
6131 commands from client more frequently, timeout is registered
6132 to process the commands. Affected file silcd/command.c.
6133 Added new function silc_server_command_process_timeout.
6135 * Changed NICK_NOTIFY handling in client library to check that
6136 if the client's nickname was changed, so there is no need to
6137 resolve anything from the server.
6139 * Removed error printing from the WHOIS and IDENTIFY commands.
6140 If error occurs then it is ignored silently in the client library.
6141 The application, however, may map the received error to
6142 human readable error string. The application currently maps
6143 the NO_SUCH_NICKNAME error to string.
6145 * Made the command status message public to the application. Moved
6146 them from lib/silcclient/command_reply.c to
6147 lib/silcclient/command_reply.h. The application can map the
6148 received command status to the string with the
6149 silc_client_command_status_message function.
6151 * Added check to the server to check that client's ID is same
6152 as the Source ID in the packet the client sent. They must
6155 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6157 * Added dist-bzip hook to the Makefile.am to make bzip2
6158 compressed distributions.
6160 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6162 * Server now enforces the maximum length for the nickname and
6163 the channel as protocol specification dictates. 128 bytes for
6164 nickname and 256 bytes for channel name.
6166 * Moved the WHOIS printing to the application. The client libary
6167 does not print out the WHOIS information anymore, the application
6168 must do it. Renamed silc_client_command_reply_whois_print to
6169 the silc_client_command_reply_whois_save.
6171 The client's idle time is also sent to the application now, and
6172 the idle is shown on screen.
6174 * Added silc_client_command_reply_identify_save to save the
6175 received IDENTIFY entries.
6177 * Do not check for channel private keys in message sending and
6178 reception if the channel does not have the PRIVKEY mode set.
6179 Affected file lib/silclient/client_channel.c.
6181 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6183 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
6184 just surfaced after chaning the JOIN procedure.
6186 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6188 * Added silc_client_get_clients_by_list to get client entries
6189 from Client ID list, that is returned for example by JOIN
6190 and USERS command replies. The application should use this
6191 function for example when JOIN command reply is received to
6192 resolve the clients already on the channel (library does not
6193 do that anymore as USERS command reply is not used in the JOIN
6194 procedure anymore). Affected files lib/silcclient/silcapi.h and
6195 lib/silcclient/idlist.c.
6197 * JOIN command reply and USERS command reply returns now SilcBuffer
6198 pointers instead of unsigned char pointers when returning
6199 the client list and mode list.
6201 * Added <Client ID> argument to the JOIN command reply, mainly
6202 for the server to identify for which client the command was
6203 originally sent. Updated protocol specs accordingly.
6205 * Added SilcDlist private_key pointer to the SilcChannelEntry
6206 in the client to support the channel private keys. Affected
6207 file is lib/silcclient/idlist.h.
6209 * Added SilcChannelPrivateKey argument to the function
6210 silc_client_send_channel_message so that application can choose
6211 to use specific private ke if it wants to. If it is not provided,
6212 the normal channel key is used, unless private keys are set.
6213 In this case the first (key that was added first) is used
6214 as the encryption key.
6216 * Implemented the support for channel private key handling.
6217 Implemented the following functions:
6219 silc_client_add_channel_private_key,
6220 silc_client_del_channel_private_keys,
6221 silc_client_del_channel_private_key,
6222 silc_client_list_channel_private_keys and
6223 silc_client_free_channel_private_keys
6225 Affected file lib/silcclient/client_channel.c.
6227 * Added the support for the private keys in the channel message
6228 sending and encryption and in the message reception and
6229 decryption. Affected funtions are
6230 silc_client_send_channel_message and silc_client_channel_message.
6232 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6234 * Added SKE's key verify callback to the client library's
6235 KE protocol context. Affected files lib/silcclient/protocol.[ch].
6237 * Removed the statement that server (or router) must send USERS
6238 command reply when joining to the channel so that the client
6239 knows who are on the channel. Instead, the client list and
6240 client's mode list is now sent in the JOIN command reply to the
6241 client who joined channel. This is better solution.
6243 * Added function silc_server_get_users_on_channel and function
6244 silc_server_save_users_on_channel to the silcd/server.[ch].
6246 * Removed function silc_server_command_send_users from the
6249 * Do not show topic on the client library anymore. The topic is
6250 sent in the command reply notify to the application and the
6251 application must show the topic now.
6253 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6255 * Added client searching by nickname hash into the IDENTIFY and
6256 WHOIS commands in the server as they were clearly missing from
6257 them. Affected file is silcd/command.c.
6259 * Fixed a bug in private message receiving in the client library.
6260 The remote ID was freed and it wasn't supposed, now it is
6263 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6265 * Minor fix to the channel payload; allocate the data area, as it
6266 needs to be of specific length.
6268 * If the key agreement port is zero then the operating
6269 system will define the bound port. Affected files are
6270 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
6272 * Added new function silc_channel_payload_decrypt into the file
6273 lib/silccore/silcchannel.[ch].
6275 * Moved the channel message etc, check from silc_packet_decrypt
6276 to applications. The library calls now a generic
6277 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
6278 when the packet is either normal or special. This was done to
6279 allow more wide range of checking that was not allowed when
6280 the code was in library. Now applications can do virtually any
6281 checks to the packet and return to the library the decision how
6282 the packet should be processed. Affected files are
6283 lib/silccore/silcpacket.[ch].
6285 Added silc_server_packet_decrypt_check to the server and
6286 silc_client_packet_decrypt_check to the client library.
6288 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
6289 to send with specified source and destination information.
6291 * Channel message delivery between routers was broken after the
6292 channel key distribution was fixed earlier. The channel key
6293 was used be to distributed to other routers as well which is not
6294 allowed by the protocol. Now this is fixed and channel keys
6295 really are cell specific and the channel message delivery between
6296 routers comply with the protocol specification.
6298 * Fixed various commands in server to check also the global list
6299 for the channel entry and not just the local list. The affected
6300 file silcd/command.c.
6302 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6304 * Added assert()s to buffer formatting and unformatting routines
6305 to assert (if --enable-debug) when error occurs. Affected
6306 file: lib/silcutil/silcbuffmt.c.
6308 * Changed to auto-reconnect to check whether the remote host is
6309 router and register the re-connect timeout if it is. It used
6310 to check that whether we are normal server, but router must do
6311 auto-reconnect with another router as well. Affected file
6314 * Removed the [<key len>] option from CMODE command as the cipher
6315 name decides the key length, nowadays. See the defined ciphers
6316 from the protocol specification.
6318 * Added [<hmac>] option to the CMODE command to define the HMAC
6319 for the channel. Added SILC_CMODE_HMAC channel mode.
6321 * Added [<hmac>] option for the JOIN command so that user can
6322 select which HMAC is used to compute the MACs of the channel
6325 * Added Hmac field to the Channel Message Payload. The integrity
6326 of plaintext channel messages are now protected by computing
6327 MAC of the message and attaching the MAC to the payload. The
6328 MAC is encrypted. Now, it is clear that this causes some
6329 overhead to the size of the packet but rationale for this is that
6330 now the receiver can verify whether the channel message decrypted
6331 correctly and also when private keys are set for the channel the
6332 receiver can decrypt the packet with several keys and check from
6333 the MAC which key decrypted the message correctly.
6335 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
6336 lib/silccrypt/silccipher.[ch].
6338 * Added silc_hash_len to return the digest length into the
6339 lib/silcrypt/silchash.[ch].
6341 * Rewrote parts of Silc Channel Payload interface in the
6342 lib/silccore/silcchannel.[ch]. The encode function now also
6343 encrypts the packet and parse function decrypts it.
6345 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6347 * Fixed a minor formatting bug in the SKE's key material processing.
6348 It actually might have processed the keys wrong way resulting
6351 * Redefined the mandatory HMAC algorithms and added new algorithms.
6352 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
6353 and hmac-md5 truncated to 96 bits. The mandatory is now
6354 hmac-sha1-96. Rest are optional (including the one that used
6355 to be mandatory). Rationale for this is that the truncated HMAC
6356 length is sufficient from security point of view and can actually
6357 make the attack against the HMAC harder. Also, the truncated
6358 HMAC causes less overhead to the packets. See the RFC2104 for
6361 * Added new [hmac] configuration section. The SKE used to use
6362 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
6363 is of course wrong. The official names that must be proposed in
6364 the SKE are the ones defined in the protocol specification
6365 (hmac-sha1-96 for example). The user can configure any hmac
6366 using any hash function configured in the [hash] section. At
6367 least, the mandatory must be configured.
6369 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
6371 * Added HMAC list to the SKE proposal list. It has now both
6372 hash algorithm list and HMAC list. This makes the protocol
6373 incompatible with previous versions. The SKE now seems to work
6374 the way it is supposed to work, for the first time actually.
6376 * Defined plain Hash algorithms to the protocol specification.
6379 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6381 * Implemented support for key agreement packets into the server.
6382 Added functions silc_server_key_agreement and
6383 silc_server_send_key_agreement. Other than these functions,
6384 server has nothing to do with this packet.
6386 * Added support for private message key packets into the server.
6387 Added functions silc_server_private_message_key and
6388 silc_server_send_private_message_key.
6392 * Changed the silc_[client|server]_protocol_ke_set_keys to be
6393 called in the protocol's final callback instead in the END
6394 protocol state. This makes a little more sense and in the same
6395 time in client we can use the same protocol routines for normal
6396 key exchange and to key agreement packet handling as well.
6398 * Added to both client's and server's KE protocol context the
6399 SilcSKEKeyMaterial pointer to save the key material. We will
6400 bring the key material to the protocol's final callback by doing
6401 this. The final callback must free the key material.
6403 * Added SKE's packet_send callback into client's KE protocol
6404 context so that the caller can choose what packet sending function
6405 is used. This way we can use different packet sending when
6406 doing normal SKE when doing key agreement packet handling (in
6407 the key agreement packet handling we do not want to encrypt
6410 * Implemented the responder side of the key agreement routines
6411 in the client. The client can now bind to specified port and
6412 accept incoming key negotiation. The key material is passed
6413 to the application after the protocol is over.
6415 * Implemented the processing of incoming Key Agreement packet
6416 in the client. Added function silc_client_key_agreement to
6419 * Implemented the intiator side of the key agreement routines
6420 in the client. The client can now initiate key agreement with
6421 another remote client. The key material is passed to the
6422 application after the protocol is over.
6424 * Created client_keyagr.c to include all the key agreement
6427 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
6428 SILC_TASK_CALLBACK except that it is not static.
6430 * Created client_notify.c and moved the Notify packet handling
6431 from the client.[ch] into that file.
6433 * Created client_prvmsg.c and moved all private message and
6434 private message key routines from the client.[ch] into that file.
6436 * Create client_channel.c and moved all channel message and
6437 channel private key routines from the client.[ch] into that file.
6439 * Changed silc_client_get_client_by_id_resolve to resolve with
6440 WHOIS command instead of IDENTIFY command, in the file
6441 lib/silclient/idlist.c.
6443 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6445 * Implemented the SKE's responder side to the Client library.
6447 * When FAILURE is received to the protocol do not trust it
6448 blindly. Register a timeout to wait whether the remote closes
6449 the connection as it should do it, only after that process the
6450 actual failure. This was changed to both client and server.
6452 * Added client_internal.h to include some of the structures
6453 there instead of client.h in lib/silcclient/.
6455 * Added function silc_task_unregister_by_callback to unregister
6456 timeouts by the callback function.
6458 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6460 * Some "Incomplete WHOIS info" errors has been appearing on the
6461 log files. Took away the entry->userinfo check from WHOIS
6462 reply sending. The entry->userinfo is now " " if client did not
6463 provide one. I thought this was fixed earlier but something
6464 is wrong still. Let's see if the error still appears.
6466 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6468 * Fixed a minor bug in the login when the channel key is
6469 re-generated in the server. It used to generate the key in
6470 wrong order and thus caused problems in the channel traffic.
6472 * Fixed a minor bug in channel key distsribution after
6473 KICK command. The key was not sent to the router even though
6476 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6478 * Added silc_ske_process_key_material_data as generic routine
6479 to process any key material as the SILC protocol dictates. The
6480 function is used by the actual SKE library but can be used by
6481 applications as well. This relates to the private message keys
6482 and the channel private keys since they must be processed the
6483 same way the normal SILC session keys. The protocol dictates
6484 this. Affected files: lib/silcske/silcske.[ch].
6486 Added also silc_ske_free_key_material to free the
6487 SilcSKEKeyMaterial structure.
6489 * Defined silc_cipher_set_key function to set the key for
6490 cipher without using the object's method function. The affected
6491 files: lib/silccrypt/silccipher.[ch].
6493 * Implemented silc silc_client_add_private_message_key,
6494 silc_client_add_private_message_key_ske,
6495 silc_client_del_private_message_key,
6496 silc_client_list_private_message_keys and
6497 silc_client_free_private_message_keys functions in the
6500 Added functions silc_client_send_private_message_key to send
6501 the Private Message Key payload and silc_client_private_message_key
6502 to handle incoming Private Message Key payload.
6504 * Added Cipher field to the Private Message Key payload to set
6505 the cipher to be used. If ignored, the default cipher defined
6506 in the SILC protocol (aes-256-cbc) is used.
6508 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6510 * Removed lib/silcclient/ops.h file.
6512 Redefined parts of the SILC Client Library API. Created new
6513 file silcapi.h that deprecates the ops.h file and defines the
6514 published Client Library API. Defined also private message key
6515 API and channel private key API into the file.
6517 This is the file that the application must include from the
6518 SILC Client Library. Other files need not be included by
6519 the application anymore.
6521 * Added new key_agreement client operation callback and also
6522 defined the Key Agreement library API for the application.
6524 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6526 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
6527 is used by clients to request key negotiation between another
6528 client in the SILC network. If the negotiation is started it
6529 is performed using the SKE protocol. The result of the
6530 negotiation, the secret key material, can be used for example
6531 as private message key.
6533 Implemented the Key Agreement payload into the files
6534 lib/silccore/silauth.[ch].
6536 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6538 * Redefined ciphers for the SILC protocol. Added some new ciphers
6539 and defined the key lengths for the algorithms. Changed the
6540 code accordingly. The default key length is now 256 bits.
6542 * Fixed SKE key distribution function silc_ske_process_key_material
6543 when the key length is more than 128 bits. The default key
6544 length in SILC is now 256 bits.
6546 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
6547 to indicate unsupported algorithm.
6549 * Renamed rijndael.c to aes.c and all functions as well.
6551 * Fixed a long standing channel key setting bug in client library.
6552 Weird that it has never surfaced before.
6554 * Fixed bug in channel deletion. If the entire channel is removed
6555 then it must also delete the references of the channel entry
6556 from the client's channel list as the client's channel entry and
6557 the channel's client entry share same memory.
6559 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6561 * Implemented CONNECT and SHUTDOWN commands in the client.
6563 * Implemented CLOSE command to the client.
6565 * Added the function silc_idlist_find_server_by_name into the
6566 files silcd/idlist.[ch].
6568 Added the function silc_idlist_find_server_by_conn into the
6569 files silcd/idlist.[ch].
6571 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6573 * DIE command was renamed to SHUTDOWN. Updated the both code
6576 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
6577 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
6579 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
6582 * Added function silc_server_create_connection function to create
6583 connection to remote router. My server implementation actually
6584 does not allow router to connect to normal server (it expects
6585 that normal server always initiates the connection to the router)
6586 so the CONNECT command is only good for connecting to another
6589 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6591 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
6592 or some other client was kicked from the channel.
6594 Implemented the handling of the notify type to both client
6597 Implemented silc_server_send_notify_kicked to send the KICKED
6598 notify. It is used to send it to the server's primary router.
6600 * Implemented the KICK command into server and client.
6602 * Added `query' argument to the silc_idlist_get_client function
6603 to indicate whether to query the client from server or not if
6606 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
6607 to indicate that the client is not channel founder.
6611 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6613 * Removed the rng context from SilcPacketContext structure and
6614 changed that the packet routine uses the Global RNG API.
6616 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6618 * Added support for quit message that client can "leave" on the
6619 channel when it quits the SILC. It is ditributed inside the
6620 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6622 Added silc_server_free_client_data that will take the
6623 signoff message as argument.
6625 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6627 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6629 * Updated parts of the protocol specification to keep it up
6632 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6634 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6635 payloads in one packet.
6637 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6638 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6639 use now the new List flag.
6641 * Also deprecated the following packet types: REPLACE_ID,
6642 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6644 * Added list support for Notify packet in server.
6646 * Added silc_server_send_notify_channel_change to send the
6647 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6648 the silc_server_send_replace_id.
6650 * Added silc_server_send_notify_nick_change to send the
6651 NICK_CHANGE notify type. Deprecates the function
6652 silc_server_send_replace_id.
6654 * Added silc_server_send_notify_join to send the JOIN notify type.
6655 Deprecates the function silc_server_send_new_channel_user.
6657 * Added silc_server_send_notify_leave to send LEAVE notify type.
6658 Deprecates the function silc_server_send_remove_channel_user.
6660 * Added silc_server_send_notify_cmode and
6661 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6662 types. Deprecates the silc_server_send_set_mode function.
6664 * Added SERVER_SIGNOFF notify type to indicate that server has
6665 quit. This means that all clients on the channel from that
6666 server will drop. This can be also used when netsplit happens.
6668 Deprecated REMOVE_ID packet type since it is not needed anymore
6671 Added silc_server_send_notify_server_signoff to send the
6672 SERVER_SIGNOFF notify type. Deprecates the function
6673 silc_server_send_remove_id.
6675 Added also silc_server_send_notify_signoff to send the
6676 SIGNOFF notify type.
6678 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6679 SILC protocol from this day on. Changed the protocol
6680 specification as well.
6682 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6683 notify type. It is used between routers to notify about
6684 topic changes on a channel.
6686 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6689 * Partly updated the protocol specification to comply with the
6690 changes now made. It is still though a bit outdated.
6692 * The JOIN notify type now takes one extra argument <Channel ID>.
6693 The packet used to be destined to the channel but now the
6694 JOIN type may be sent as list thus it is impossible to
6695 destine it to any specific channel. By adding this argument
6696 it is again possible.
6698 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6700 * Added CREDITS file. The CHANGES and CREDITS file will appear
6701 in the distribution as well.
6703 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6705 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6706 types in the server's silcd/packet_receive.c.
6708 * Implemented CMODE and CUMODE to work in router environment.
6710 * Fixed minor encoding and decoding buglet from the
6711 lib/silccore/silcmode.c.
6713 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6716 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6718 * Changed all SilcConfigServer* and silc_config_server* to
6719 SilcServerConfig* and silc_server_config*, respectively.
6722 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6724 * Associated the ID (client or server ID) to the Authentication
6725 Payload to avoid any possibility of forging. Updated the
6726 protocol specification and the code accordingly.
6728 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6730 * The RSA key length is now save to the RsaKey context in the
6731 key generation process in lib/silccrypt/rsa.c. The key length
6732 is now used to figure out the maximum size of the block allowed
6733 to be encrypted/signed.
6735 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6736 is equivalent to the silc_mp_mp2bin but does not allocate any
6739 * Changed silc_mp_mp2bin API to take length argument. If it is
6740 non-zero then the buffer is allocated that large. If zero, then
6741 the size is approximated using silc_mp_sizeinbase, which however
6744 * Created Global RNG API which is global RNG that application can
6745 initialize. After initializing, any routine anywhere in the
6746 code (including library) can use RNG without allocating a new
6747 RNG object. This was done to allow this sort of use of the
6748 RNG in code that has no chance to allocate RNG object. All
6749 applications currently allocate this and many routines in the
6750 library use this. Affected file lib/silccrypt/silcrng.[ch].
6752 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6753 it to use the Global RNG API.
6755 * Defined Authentication Payload into protocol specification that
6756 is used during SILC session to authenticate entities. It is
6757 used for example by client to authenticate itself to the server
6758 to obtain server operator privileges.
6760 Implemented this payload into the lib/silccore/silcauth.[ch].
6761 Implemented also routines for public key based authentication
6762 as the new protocol specification dictates.
6764 Moved definitions of different authentication methods from
6765 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6767 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6768 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6769 silc_pkcs_verify_with_hash functions into the file
6770 lib/silccrypt/silcpkcs.[ch].
6772 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6774 * The client entry's userinfo pointer must be always valid.
6775 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6776 will fail since it requires the userinfo. Now, the userinfo
6777 is allocated as "" if actual userinfo does not exist. Actually,
6778 it must exist and it is totally Ok to drop client connections
6779 that does not announce the userinfo. However, we will make
6780 this workaround for now.
6782 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6783 to return the remote port by socket.
6785 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6787 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6788 SILC_SERVER_PENDING_EXEC and added an new macro
6789 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6790 data or when error occurs while processing the pending command.
6792 Added new argument `destructor' into silc_server_command_pending
6793 and to the SilcServerCommandPending object. This destructor is
6794 now called after calling the pending callback or if error occurs
6795 immediately. If error occurs the actual pending callback won't
6796 be called at all - only the destructor. The destructor may be
6797 NULL if destructor is not needed.
6799 All this applies for client library code as well. Similar
6800 changes were made there as well for the pending commands.
6802 In the client, the application must now allocate the
6803 SilcClientCommandContext with the silc_client_command_alloc
6806 * Added reference counter to the SilcServerCommandContext. Added
6807 function silc_server_command_alloc and silc_server_command_dup
6810 Same type of functions added to the client library for the same
6813 * Removed the cmd_ident from IDListData away since it is now
6814 global for all connections. It is the command identifier used
6815 in command sending and with pending commands. The affected file
6818 * Added reference counter to the SilcSocketConnection objecet to
6819 indicate the usage count of the object. The object won't be
6820 freed untill the reference counter hits zero. Currently only
6821 server uses this, and client ignores it. The client must be
6822 set to use this too later. The affected files are
6823 lib/silccore/silcsockconn.[ch]. Added also the function
6824 silc_socket_dup to increase the reference counter.
6826 This was mainly added because it is possible that the socket
6827 is removed underneath of pending command or other async
6828 operation. Now it won't be free'd and proper DISCONNECTING
6829 flags, etc. can be set to avoid sending data to connection that
6830 is not valid anymore.
6832 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6833 the connection. After that it sets SILC_SET_DISCONNECTED.
6834 It is, however, possible that the socket data is not still freed.
6835 The silc_server_packet_process now checks that data is not
6836 read or written to connection that is DISCONNECTED. The socket
6837 get's freed when the reference counter hits zero.
6839 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6841 * Changed the client operation API: channel_message operation's
6842 `sender' is now the client entry of the sender, not the nickname
6843 and the `channel' is the channel entry, not the channel name.
6845 In the private_message operation the `sender' is now also the
6846 client entry of the sender not the nickname.
6848 Affected file is lib/silcclient/ops.h and all applications
6849 using the client operations.
6851 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6853 * Moved the calling of ops->connect() from connect_to_server_final
6854 into receive_new_id functin since that is the point when the
6855 client is actually allowed to send traffic to network. The
6856 affected file is lib/silcclient/client.c.
6858 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6860 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6861 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6862 (if needs broadcasting) instead of broadcasting the packets one
6863 by one which would make a burst in the network traffic.
6865 * Added `broadcast' argument to the functions in silcd/server.[ch]
6866 silc_server_create_new_channel[_with_id] to indicate whether
6867 to send New Channel packet to primary router.
6869 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6871 * Added new function into the silcd/server.[ch] files:
6872 silc_server_create_new_channel_with_id to create new channel with
6873 already existing Channel ID.
6875 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6876 lib/silccore/silcpacket.h. This packet is used t send list of
6877 Set Mode payloads inside one packet. Server uses this to set
6878 the modes for the channels and clients on those channels, that it
6879 announced to the router when it connected to it. The protocol
6880 specification has been updated accordingly.
6882 * The silc_server_new_channel did not handle the packet coming
6883 from normal server as it normally does not send that. However,
6884 when it announces its channels it does send it. Implemented
6885 the support for that.
6887 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6888 into the file lib/silccore/id.h.
6890 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6892 * Fixed memory leaks in the functions silc_idlist_del_client,
6893 silc_idlist_del_channel and silc_idlist_del_server in the file
6894 silcd/idlist.c. All of those leaked like a sieve.
6896 * Fixed some small memory leaks in the client's function
6897 silc_client_notify_by_server.
6899 * Added functions into silcd/server.c: silc_server_announce_clients,
6900 silc_server_announce_channels and silc_server_announce_server.
6901 These functions are used by normal and router server to announce
6902 to its primary router about clients, channels and servers (when
6903 router) that we own. This is done after we've connected to the
6906 These functions effectively implements the following packet types:
6907 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6908 and SILC_PACKET_NEW_ID_LIST.
6910 * Added new functions into the silcd/packet_receive.[ch]:
6911 silc_server_new_id_list, silc_server_new_channel_list and
6912 silc_server_new_channel_user_list to handle the incoming
6913 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6915 * Added support of changing Channel ID in the function
6916 silc_server_replace_id. If the server that announces a channel
6917 to the router already exists in the router (with same name but
6918 with different Channel ID), router is responsible to send
6919 Replace ID packet to the server and force the server to change
6920 the Channel ID to the one router has.
6922 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6923 client that the Channel ID has been changed by the router. The
6924 normal server sends this to the client. Client must start using
6925 the new Channel ID as the channel's ID.
6927 Implemented handling of this new type into lib/silcclient/client.c
6928 into the function silc_client_notify_by_server.
6930 * Added new function silc_idlist_replace_channel_id into the files
6931 silcd/idlist.[ch] to replace the Channel ID.
6933 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6935 * Call silc_server_command_identify_check always when processing
6936 the IDENTIFY command in silcd/command.c
6938 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6940 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6941 send keepalive packets. The packet can be sent by clients,
6942 servers and routers.
6944 Added function silc_socket_set_heartbeat into the file
6945 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6946 If not set, the heartbeat is not performed. The actual
6947 heartbeat is implemented in the low level socket connection
6948 library. However, application is responsible of actually
6951 Added silc_server_send_heartbeat to send the actual heartbeat
6952 packet into silcd/packet_send.[ch]. Server now performs
6953 keepalive with all connections.
6955 * Added silc_task_get_first function into lib/silcutil/silctask.c
6956 to return the timeout task with shortest timeout. There was a bug
6957 in task unregistration that caused problems. TODO has been
6958 updated to include that task system must be rewritten.
6960 * The client library will now resolve the client information when
6961 receiving JOIN notify from server for client that we know but
6962 have incomplete information.
6964 * Rewrote parts of silc_server_remove_from_channels and
6965 silc_server_remove_from_one_channel as they did not remove the
6966 channel in some circumstances even though they should've.
6968 * Encryption problem encountered in server:
6970 The LEAVE command used to send the Channel Key packet to the
6971 router immediately after generating it. However, the code
6972 had earlier sent Remove Channel user packet but not immediately,
6973 ie. it was put to queue. The order of packets in the router
6974 was that Channel Key packet was first and Remove Channel User
6975 packet was second, even though they were encrypted in the
6976 reverse order. For this reason, MAC check failed. Now, this
6977 is fixed by not sending the Channel Key packet immediately but
6978 putting it to queue. However, this is more fundamental problem:
6979 packets that are in queue should actually not be encrypted
6980 because packets that are sent immediately gets encrypted
6981 actually with wrong IV (and thus MAC check fails). So, packets
6982 that are in queue should be encrypted when they are sent to
6983 the wire and not when they put to the queue.
6985 However, the problem is that the current system has not been
6986 designed to work that way. Instead, the packet is encrypted
6987 as soon as possible and left to the queue. The queue is then
6988 just purged into wire. There won't be any fixes for this
6989 any time soon. So, the current semantic for packet sending
6992 o If you send packet to remote host and do not force the send
6993 (the packet will be in queue) then all subsequent packets to the
6994 same remote host must also be put to the queue. Only after the
6995 queue has been purged is it safe again to force the packet
6998 o If you send all packets immediately then it safe to send
6999 any of subsequent packets through the queue, however, after
7000 the first packet is put to queue then any subsequent packets
7001 must also be put to the queue.
7003 Follow these rules and everything works fine.
7005 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7007 * Added new function silc_server_remove_clients_by_server to
7008 remove all client entries from ID list when the server connection
7009 is lost. In this case it is also important to invalidate all
7010 client entires as they hold the invalid server entry. This
7011 fixes fatal bug when server has lost connection and will reconnect
7014 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7016 * Made some sanity checks to silc_server_daemonise like to check
7017 whether the requested user and group actually exists.
7019 * Added sanity check to SKE's silc_ske_responder_finish to check
7020 that the public and private key actually is valid.
7022 * Invalidate the client's nickname when receiving Replace ID
7023 packet and the Client ID is being replaced. This means that the
7024 server will query the nickname if someone needs it (client)
7027 * Sort the ID Cache in client library when the ID Cache data
7028 has changed (needs sorting).
7030 * Do not allow for SILC client to create several connections to
7031 several servers. The client does not support windows right now
7032 and generating multiple connections causes weird behaviour.
7034 Irssi-silc client does support windows and can handle several
7035 connections without problems, see: www.irssi.org and SILC plugin.
7037 * Fixed some places where client was added to the IDList. The
7038 rule of thumb is following (in order to get everything right):
7039 If the client is directly connected local client then the
7040 `connection' argument must be set and `router' argument must be
7041 NULL to silc_idlist_add_client function. If the client is not
7042 directly connected client then the `router' argument must
7043 bet set and the `connection' argument must be NULL to the
7044 silc_idlist_add_client function.
7046 * The funtion silc_server_packet_send_local_channel actually did
7047 not check whether the client was locally connected or not. It
7048 does that now. Fixed a bug related to LEAVE command.
7050 * Fixed Remove Channel User payload parsing bug in server's
7051 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
7053 * The server's silc_server_save_channel_key now checks also the
7054 global ID list for the channel as it might not be in the local
7055 list. Fixed a bug related to LEAVE command.
7057 * Is this the end of the [<unknown>] buglet that has been lurking
7058 around for a long time? A little for loop fix in server's
7059 silc_server_command_whois_parse that is used by both IDENTIFY
7060 and WHOIS command. At least, this was a clear bug and a cause
7061 of one type of [<unknown>] buglet.
7063 * WHOIS and IDENTIFY commands call the function
7064 silc_server_command_[whois/identify]_check function even if
7065 we are not router server.
7067 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7069 * Added --with-gmp configuration option. If set the GMP
7070 is always compiled in the SILC source tree. If not set then
7071 it is checked whether the system has the GMP3 installed. If
7072 it has then the GMP won't be compiled (the system's headers
7073 and library is used), if it doesn't have it then the GMP is
7074 compiled in the SILC source tree.
7076 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7078 * Changed RSA private exponent generation to what PKCS #1
7079 suggests. We try to find the smallest possible d by doing
7080 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
7081 not security fix but optimization.
7083 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7085 * Added new config entry [Identity] to fork the server and run
7086 it as specific user and group. A patch from Bostik.
7088 * Imported Dotconf configuration library into lib/dotconf.
7089 This will be used to create the SILC configuration files later.
7090 It will appear in the distsribution after this commit.
7092 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7094 * A big code auditing weekend happening. Auditing code for
7095 obvious mistakes, bugs and errors. Also, removing any code
7098 Removed files for being obsolete:
7100 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
7101 inline in the file lib/silcutil/silcbuffer.h)
7103 o lib/silcutil/silcbufutil.c (the header has inline versions)
7105 Changed code to fix possible error conditions:
7107 o The buffer formatting routines now check that the destination
7108 buffer really has enough space to add the data. This applies for
7109 both buffer formatting and unformatting
7110 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
7111 unformatting was changed to accomodate following rules:
7112 XXX_*STRING_ALLOC will allocate space for the data into the pointer
7113 sent to the function while XXX_*STRING will not allocate or copy
7114 the data into the buffer. Instead it sets the pointer from the
7115 buffer into the pointer sent as argument (XXX_*STRING used to
7116 require that the pointer must be allocated already). This change
7117 makes this whole thing a bit more consistent and more optimized
7118 (note that the data returned in the unformatting with XXX_*STRING
7119 must not be freed now). The routines return now -1 on error.
7121 o Tried to find all code that use buffer_format and buffer_unformat
7122 and added return value checking to prevent formatting and
7123 especially unformatting errors and possible subsequent fatal
7126 o Changed ske->x and ske->KEY to mallocated pointers in
7127 lib/silcske/silcske.h. Fixed possible data and memory leak.
7129 o Added return value checking to all *_parse* functions. Fixed
7130 many memory leaks as well.
7132 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
7133 so that buffer overflows would not happen. All code now also
7134 checks the return value as it can fail.
7136 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7138 * Added reconnection support to server if the normal server looses
7139 its connection to the router (for example if router is rebooted).
7140 The server performs normal reconnection strategy implemented
7141 to the server. Affected file silcd/server.c.
7143 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7145 * Added new packet type SILC_PACKET_SET_MODE that is used to
7146 distribute the information about changed modes (for clients,
7147 channels and clients channel modes) to all routers in the
7148 network. Updated the protocol specification accordingly.
7150 Added functions into silcd/packet_send.c and
7151 silcd/packet_receive.c: silc_server_send_set_mode,
7152 silc_server_set_mode.
7154 Added new files silcmode.[ch] into lib/silccore that implements
7155 the encoding and decoding of Set Mode Payload. Added new type
7156 SilcSetModePayload. Moved the definitions of different modes
7157 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
7159 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7161 * Oops, a little mistake in server's connection authentication
7162 protocol. The protocol is not ended with FAILURE but with
7163 SUCCESS if the authentication is Ok. :) Affected file is
7166 * Implemented NICK_CHANGE notify handling in server in the file
7167 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
7168 the local clients on the channel. After the changing nickname
7169 in router environment snhould work and the [<unknown>] nickname
7170 should appear no more.
7172 The silc_server_replace_id function that receives the Replace ID
7173 payload now sends the NICK_CHANGE notify type also in the file
7174 silcd/packet_receive.c
7176 * Changed WHOIS and IDENTIFY command to support the maximum amount
7177 of arguments defined in protocol specs (3328 arguments). This
7178 fixed a bug that caused problems when there were more than three
7181 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7183 * Added extra parameter, command identifier, to the
7184 silc_client_send_command so that explicit command identifier
7187 Changed that ID list routines uses specific command identifier
7188 when sending WHOIS/IDENTIFY requests to the server so that they
7189 can be identified when the reply comes back.
7191 Affected files lib/silcclient/command.[ch],
7192 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
7194 * Added `sender' argument to silc_server_packet_send_to_channel
7195 to indicaet the sender who originally sent the packet to us
7196 that we are now re-sending. Ignored if NULL. Affected file
7197 silcd/packet_send.[ch].
7199 * Added some server statistics support in silcd/server_internal.h
7200 SilcServerStatistics structure and around the server code. Also
7201 send some nice statistics information when client is connecting
7204 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7206 * Fixed channel ID decoding in server's JOIN command reply in
7207 silcd/command_reply.c
7209 * Fixed braodcasting of replace ID payload to not to send it if
7210 we are standalone server in silcd/packet_receive.c.
7212 * Fixed all channel message sending routines to not to send
7213 packets to clients that has router set, since they are routed
7214 separately in the same function earlier. Affects file
7215 silcd/packet_send.c and all channel packet sending functions.
7217 * In USERS reply, res_argv[i] are not allocated, the table
7218 is allocated. Thus changed that free the table, not its
7221 * In server's whois_check and identify_check if the client is
7222 locally connected do not send any WHOIS commands - they are not
7225 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7227 * Fixed some minor bugs in client when sending WHOIS command. The
7228 arguments was in wrong order.
7230 * Removed statis function add_to_channel from server in
7231 silcd/command.c that was previously used with the joining but
7234 * Tested USERS command in router environment successfully with two
7235 routers, two servers and two clients.
7237 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7239 * Reorganized the USERS command and command reply in client library
7240 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
7241 When the command is given by user we register a pending command
7242 callback that will reprocess the command after the reply has been
7243 received from the server. When reprocessing the packet we then
7244 display the information. Thus, the USERS information is displayed
7245 now in the command callback instead of in the command reply
7246 callback. The processing of the command is same as previously
7247 when server has sent the command reply in the JOINing process.
7249 * Added to USERS command in silcd/command_reply.c to join the client,
7250 we didn't use to know about, to the channel after we've created
7251 a client entry for it. Also, for clienet we did know already still
7252 check whether it is on the channel or not and add it if not.
7254 * Removed silc_server_command_join_notify as the function and its
7257 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7259 * Changed the client's pending command handling to the same as the
7260 server's pending command handling. It is also now possible to
7261 execute command reply functions from other command reply
7262 function as the function callbacks for commands and command
7263 replies are one and same. The pending commands are not static
7264 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
7265 in client connection context. Thus, pending commands are server
7266 connection specific as it is convenient.
7268 Changed the function silc_client_command_pending and
7269 silc_client_command_pending_del and added new function
7270 silc_client_command_pending_check. Removed the
7271 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
7274 * Added cmd_ident, current command identifier, to the client
7275 connection context in lib/silcclient/client.h to keep track on
7276 command identifiers used in command sending. Client's command reply
7277 function handling now supports the mandatory command identifiers.
7279 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
7280 funtions in client to fully support pending command callbacks.
7282 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
7283 as one of the arguments to the application in the command reply
7286 * NOTE: The FORWARDED flag is depracated. It used to be depracated
7287 before first releasing SILC but came back. Now it is removed again
7288 and should come back nomore. The FORWARDED flag was used only
7289 by the JOINing procedure by forwarding the command packet to router.
7290 Now, the JOINing procedure has been changed to more generic (due
7291 to various router environment issues) and FORWARDED is not needed
7292 anymore for anything. The protocol specification is yet to be
7295 Now, removed silc_server_packet_forward from server and the flag
7296 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
7298 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7300 * Renamed NAMES command to USERS command. The NAMES was named that
7301 due to historical reasons. Now it is renamed. Also, rewrote
7302 parts of the USERS command. The nickname list is not sent anymore
7303 by the server. Only Client ID and mode lists are sent in the USERS
7304 command. Changed this also to the protocol specification.
7306 The client now resolves the names and stuff after it receives
7307 the USERS list from the server when joining to the channel.
7309 * WHOIS and IDENTIFY commands has been changed to support multiple
7310 Client ID's per command. One can now search for multiple users
7311 in the network by sending only one WHOIS or IDENTIFY command.
7312 Changed the code and the protocol specifications.
7314 * Removed silc_server_command_identify_parse and changed that IDENTIFY
7315 uses silc_server_command_whois_parse to parse the request. */
7317 * If normal server, do not parse the WHOIS and IDENTIFY requests
7318 before sending it to the router. Saves some time.
7320 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7322 * Fixed JOIN command on client library. Wrong number of arguments
7323 used to crash the client.
7325 * Added silc_server_channel_has_global function to check whether
7326 channel has global users or not.
7328 * Added silc_server_channel_has_local function to check whether channel
7329 has locally connected clients on the channel.
7331 * The silc_server_remove_from_one_channel now checks whether the
7332 channel has global users or not after given client was removed from
7333 the channel. It also checks whether the channel has local clients
7334 on the channel anymore. If it does not have then the channel entry
7335 is removed as it is not needed anymore.
7337 * The silc_server_notify now checks on JOIN notify whether the joining
7338 client is one of locally connected or global. If it is global then
7339 the channel has now global users on the channel and that is marked
7340 to the channel entry. Also, it now saves the global client to
7341 global list who is joining and JOINs it to the channel. This is
7342 for normal server, that is.
7344 Changed silc_server_send_notify_on_channel,
7345 silc_server_packet_relay_to_channel and
7346 silc_server_packet_send_to_channel check if we are normal server
7347 and client has router set (ie. global client) do not send the
7348 message to that client, as it is already routed to our router.
7350 * Implemented LEAVE notify type handling in silc_server_notify
7353 * Tested LEAVE command in router environment successfully. Tested
7354 with two routers, two servers and two clients.
7358 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
7360 * Implemented SIGNOFF notify type handling in silc_server_notify
7363 * silc_server_remove_id now removes the client entry from all channels
7364 it has joined and thusly sends SIGNOFF notify type.
7366 * Rewrote the NAMES list generation in server by removing two excess
7367 loops. The lists are created now inside one loop.
7369 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7371 * silc_server_remove_channel_user checks now also global list
7372 for channel and client.
7374 * silc_server_new_channel_user checks now both local and global
7375 list for channel and client. Fixed a bug in client id decoding.
7376 Used to decode wrong buffer.
7378 * silc_server_channel_message checks now both local and global
7379 list for channel entry.
7381 * Tested channel joining (hence JOIN) in router environment
7382 successfully. Tested with two routers, two servers and two
7385 * Tested channel message sending in router environment successfully.
7387 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7389 * Added silc_server_save_channel_key into server.[ch] to save the
7390 received channel key in Channel Key payload processing. It is
7391 also used in JOIN command reply handling.
7393 Equivalent function silc_client_save_channel_key added into
7394 client.[ch] into client library.
7396 * Changed JOIN command reply to send information whether the channel
7397 was created or not (is existing already) and the channel key
7398 payload. Changed protocol specs accordingly.
7400 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
7401 the request was sent by ID and not by nickname. Crashed on
7404 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7406 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
7407 now correctly save the received data.
7409 * silc_server_free_sock_user_data now notifies routers in the
7410 network about entities leaving the network.
7412 At the same time implemented functions silc_server_remove_id
7413 and silc_server_send_remove_id to receive and send REMOVE_ID
7414 packets. The packet is used to notify routers in the network
7415 about leaving entities. The ID removed will become invalid in
7418 * Added function silc_idlist_del_server into server. Removes and
7419 free's server entry from ID list.
7421 * silc_server_private_message function now checks, if we are router,
7422 that the destination ID really is valid ID, naturally.
7424 * In router when NEW_ID packet is received (for new client) the
7425 hash of the Client ID is saved in the ID Cache but the
7426 client->nickname is set to NULL, instead of putting the hash
7429 IDENTIFY command now also checks that client->nickname must be
7430 valid. If it is not if will request the data from the server who
7431 owns the client. Added new function
7432 silc_server_command_identify_check.
7434 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
7435 to set the command to already allocated Command Payload.
7437 * Tested private message sending in router environment with two
7438 routers, two servers and two clients. Fixed minor bugs and now
7441 * Fixed segfault from client's NAMES command. Used to crash if
7444 * Forwarded packets must not be routed even if it is not destined
7445 to the receiver. Changed server code comply with this.
7447 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7449 * Added `require_reverse_mapping' boolean value to ServerParams
7450 structure. If TRUE (not default) the server will require that
7451 the connecting host has fully qualified domain name.
7453 If the reverse mapping is not required and hostname could not be
7454 found the IP address is used as hostname.
7456 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7458 * Implemented version string checking to both client and server.
7459 The check is incomplete currently due to the abnormal version
7460 strings used in development version of SILC.
7462 * Changed all command functions in server to use the new
7465 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7467 * Changed char *data to unsigned char *data in ID Cache system to
7468 support binary data as ID Cache data. Changed code to support
7469 binary data in lib/silccore/idcache.c.
7471 * Renamed silc_server_packet_relay_command_reply to
7472 silc_server_command_reply as it is normal packet receiving
7473 function. Rewrote the function to accept command replys for
7474 servers and not only for clients.
7476 * Mark remote router always as registered server if we are connecting
7477 to it. Otherwise, commands sent by the router to us are ignored.
7479 * All ID List find routines now returns the ID Cache Entry pointer
7480 as well if requested.
7482 * WHOIS command works now in router environment, tested with two
7483 routers, two servers and two clients.
7485 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
7486 in router environment (as it is almost equivalent to WHOIS) but
7487 hasn't been tested thoroughly. Added new functions:
7489 silc_server_command_identify_parse
7490 silc_server_command_identify_send_reply
7491 silc_server_command_identify_from_client
7492 silc_server_command_identify_from_server
7494 * Disabled route cache adding because adding two different ID's with
7495 same IP replaces the old cache entry thus giving wrong route.
7496 The entry->router->connection is always the fastest route anyway
7497 so route cache may not be needed. Of course, new routes maybe
7498 established after receiving the ID when the entry->router->connection
7499 might not be anymore the most optimal.
7501 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7503 * Add route cache for received ID for fast routing.
7505 * Added silc_server_packet_route to route received packet on router
7506 that is not destined to us.
7508 * Renamed silc_server_get_route to silc_server_route_get.
7510 * Added id_string and id_string_len fields into SilcServer to
7511 include encoded ServerID for fast comparing without excess
7512 encoding of the ID's.
7514 * Cleaned up WHOIS command on server side. Added following static
7517 silc_server_command_whois_parse
7518 silc_server_command_whois_check
7519 silc_server_command_whois_send_reply
7520 silc_server_command_whois_from_client
7521 silc_server_command_whois_from_server
7523 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
7524 arguments in command replies. All command functions should be
7525 updated to use this macro.
7527 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7529 * Minor typo fixes on command reply handling on server.
7531 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7533 * Added silc_server_command_add_to_channel internal routine to add
7534 the client to the channel after router has created the channel and
7535 sent command reply to the server.
7537 * Added generic silc_server_send_command to send any command from
7540 * Use static buffer with ID rendering instead of duplicating data.
7542 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7544 * Fixed a channel user mode bug when joining to a channel server gave
7545 everybody channel founder rights, oops.
7547 * We mark ourselves as the router of the incoming server connection
7548 if we are router ourselves. This way we can check in some packet
7549 sending functions whether it is locally connected server. For
7550 incoming router connections we put NULL.
7552 * For router sending packets locally means now always sending the
7553 packet cell wide; to local clients and local servers. For normal
7554 server sending packet locally means sending it to only local
7557 * Fixed the JOIN command to really work in router environment. If the
7558 channel is created it is always created by the router. Router is
7559 also responsible of making the initial joining to the channel,
7560 sending JOIN notify to the sending server and distributing
7561 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
7562 does not exist server doesn't do anything else but forward the
7563 command to the router which performs everything.
7565 * Added silc_server_send_channel_key function to send the Channel Key
7568 * Added silc_server_create_channel_key to create new channel key. The
7569 channel key is now re-generated everytime someone joins or leaves
7570 a channel, as protocol dictates. Note: channel->key_len is the
7573 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7575 * Splitted server.[ch] finally. Created now packet_send.[ch] and
7576 packet_receive.[ch] to separate packet sending and receiving
7577 routines. The server.[ch] now includes everything else including
7578 actual packet processing (writing and reading data) and other
7581 Renamed silc_server_private_message_send_internal to
7582 silc_server_send_private_message. The routine is still though
7583 used only to relay private messages as server does not send
7584 private messages itself.
7586 Renamed silc_server_new_channel to silc_server_create_new_channel
7587 and added new function sicl_server_new_channel that handles the
7588 incoming New Channel packet. Added also new sending function
7589 silc_server_send_new_channel to send New Channel Payload.
7591 * Added new function silc_server_notify to process incoming notify
7592 packet to the server/router. Server may then relay the notify
7593 to clients if needed.
7595 * Added new function silc_server_new_channel_user to process incoming
7596 New Channel User packet. Router will redistribute the packet and
7597 send JOIN notify to its local clients and locally connected servers
7598 if needed. Normal server will send JOIN notify to its local client
7599 on same channel when received this packet. Added also corresponding
7600 sending function silc_server_send_new_channel_user to sent the
7603 * Added boolean route argument to send_notif_to_channel and
7604 packet_send_to_channel functions to attempt to route the packet
7605 if it is TRUE and send only locally if it is FALSE.
7607 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7609 * silc_server_replace_id now broadcasts the received replace ID
7610 packet if it is not broadcast packet already. The router must
7611 broadcast to inform other routers about changed ID.
7613 * Added backpointer to server's router into SilcServer context in
7614 silcd/server_internal.h.
7616 * Fixed silc_server_packet_broadcast to send correct broadcast
7619 * The channel key is now distributed to the local client as soon
7620 as it is received from the router (in router environment) so that
7621 no other packet may be sent for the channel until client has
7624 * silc_server_remove_channel_user now broadcasts the received
7625 Remove Channel User packet if it is not broadcast packet already.
7626 The router must broadcast to inform other routers about removed
7629 * Added users field into SilcPacketContext that is a reference count
7630 of the context. One can increase the reference count by calling
7631 silc_packet_context_dup which is now changed to just increase the
7632 reference count instead of duplicating the data. The reference
7633 count is decresed by calling silc_packet_context_free that will
7634 free the data after the reference count hits zero.
7636 For now on the packet context and everything allocated into it
7637 (including the raw packet from network) must be freed by calling
7638 the new silc_packet_context_free function. Added also new function
7639 silc_packet_context_alloc that must be used now to allocate the
7640 context. This also means that if a routine is asynchronous from
7641 silc_[client/server]_packet_parse_type the packet context must
7642 be duplicated by calling silc_packet_context_dup. Otherwise it
7643 gets free'd after silc_[client/server]_packet_parse_type returns.
7644 Also, one must remember that if packet is duplicated then its
7645 reference count must be decresed by calling the free function as
7646 many times as it was duplicated.
7648 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7649 from both client and server.
7651 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7653 * Made joining to a channel working in router environment.
7655 * Cleaned up JOIN command on server side and create function
7656 silc_server_command_join_channel internal routine to make the
7659 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7661 * Changed silc_command_pending list to SilcDList. Also, added
7662 `ident' field to SilcServerCommandPending structure to identify
7663 the reply and to call correct callback.
7665 Added silc_server_command_pending_check function to replace the
7666 corresnponding macro. The silc_command_pending list is not
7669 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7670 to set identifier to previously allocated Command Payload. It
7671 is used to set identifier for command when resending Command
7674 * Added silc_command_payload_encode_payload to encode Command
7675 Payload buffer from SilcCommandPayload structure.
7677 * Added silc_argument_payload_encode_payload to encode Argument
7678 payload buffer from SilcArgumentPayload structure.
7680 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7682 * Changed WHOIS command to support router connection on server side.
7683 The whois request is always sent to router unless the server is
7684 standalone server. After server has received the reply from the
7685 router will it send the reply to the client.
7687 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7688 broadcast received broadcast packet. The function is used only
7689 by router. The broadcast packet is always sent to the router's
7692 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7693 render given ID to printable string, for log files for example.
7695 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7697 * Made basic router to router connections working. At least they
7698 can now connect to each other but nothing really works the way
7699 they are supposed - yet.
7701 * Added new initiator token to RouterConnection configuration
7702 file in silcd/serverconfig.[ch]. It is used to tell whether we
7703 are the initiator to the remote router or whether we'll expect
7704 the other end to connect.
7706 * Moved registering of listener task to silc_server_init, hence
7707 the server starts listenning as soon as it is run, even if it
7708 does not have connections to other routers. Let's see how well
7711 * Changed default connection retry timeouts for more suitable in
7714 * Removed cipher and such arguments from silc_idlist_add_client
7715 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7716 Added new function silc_idlist_add_data to add the keys and stuff
7719 * Added SilcIDListData structure and added it to SilcClientEntry
7720 and SilcServerEntry as their first field in the structure. This
7721 way we can explicitly cast the ID entries to the SilcIDListData
7722 structure and get common data for the entries. In past, we had
7723 to first check what type of connection it is and then cast it to
7724 correct ID entry type. Now, we can directly cast the opaque
7725 pointer to the SilcIDListData (no matter what ID entry it actually
7726 is) and get the data needed.
7728 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7730 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7731 in some circumstances even if threre were timeout tasks, though not
7732 IO tasks, but tasks anyway. Now fixed.
7734 * Defined SilcServerConnection structure to hold connection specific
7735 stuff about directly connected servers and routers. The definition
7736 is currently in silcd/server_internal.h. I thought about having
7737 a bit more important role fro this struct but for now it is used
7738 only when connecting to other server (or router actually).
7740 * Added connecting retry support in server when connecting to
7741 router(s). The retry feature implement exponential backoff
7742 algorithm. Also, added SilcServerParams structure to hold default
7743 parameters for server. For now, it include these retry settings
7744 and are hard coded. After server is moded to be as Silc Server
7745 Library this structure will be more important.
7747 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7749 * Changed client librarys channel->clients table to SilcList and
7750 changed code accordingly.
7752 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7754 * Changed client's channel table to SilcList and changed code
7755 accordingly. Also changed SilcChannelClientEntry to include back-
7756 pointer to the channel so that client entry can use that structure
7757 as list as well and we have fast cross-reference to the channel.
7758 This change dramatically decreased the complexity of channel
7759 handling with client entry and vice versa (removed one extra
7760 loop when searching for channel entry from many functions).
7762 * Changed server->sim from table to SilcDList and changed code
7765 * NAMES command can now be used from user interface. It will show
7766 the user list on the channel, neatly.
7768 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7769 Code now saves realname of the user if it becomes available.
7771 * Renamed configure.in to configure.in.pre and made ./prepare
7772 script to automatically add correct version string to
7773 configure.in which it creates from configure.in.pre.
7775 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7777 * NAMES command reply now shows users mode with the nickname when
7780 * Moved silc_client_ch[u]mode[_char] functions from
7781 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7782 place sucks, they are utility functions and should be in some
7785 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7787 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7790 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7794 * Added TRQ (efficient deque and list library) into lib/trq. This is
7795 a very good list library that is currently used in the SILC. Defined
7796 SilcList API over the library because I didn't like the API very
7797 much. See lib/trq/silclist.h for the API and examples of how to
7798 use the API. Fixed various places in the code to use the new
7799 SilcList API. The SilcList is meant for lists that has a structure
7800 already defined as a list. It is not suitable to add just some
7801 context to the list (in TRQ, the context is the list actually).
7803 So, I defined SilcDList that can be used for the purpose where
7804 predefined list structure does not exit. This can be used as
7805 such list. Now some context just can be added to the SilcDList.
7806 Currently this list is not used in the SILC just yet, though there
7807 are a lot places where this can replace dynamically allocated
7808 tables and I will fix these places, later, to use SilcDList.
7809 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7810 and use TRQ internally).
7812 Also fixed some annoying warning messages that the original TRQ
7813 code generated. Also minor changes to TRQ's Makefile.in.
7815 * Added support for querying by Client ID to both WHOIS and
7816 IDENTIFY commands into server, as required by the protocol.
7818 * Removed method function pointers from SilcBuffer structure. They
7819 weren't used to anything and just increased the context size for
7820 no good reason. This change also made silc_buffer_alloc and
7821 silc_buffer_free functions inline functions.
7823 * Disabled command flooding detection support until it's fixed so
7824 that it accepts commands in but does not execute them more than once
7827 * Added silc_net_localhost(), to return local hostname, into
7828 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7829 that must be initialized before calling silc_client_init.
7831 * Added new function: silc_server_send_notify_on_channels to send
7832 notify messages to all channels client has joined. It is assured
7833 that the message is sent only once per client.
7835 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7836 lib/silcutil/silcutil.[ch] as silc_format function. The new
7837 function is generic and is used by server as well, not only by
7838 the logging routines.
7840 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7841 the provided version string was not acceptable. Added new function:
7842 silc_ske_check_version into lib/silcske/silcske.h. The function
7843 must be implemented by the application (client or server) and it
7844 does not reside in the SKE library. The function checks the version
7845 string remote end sent.
7847 * Added back pointers (to opaque context and to SilcSocketConnection)
7848 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7850 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7851 duplicate packet context structure.
7853 * Changed `notify' client operation to send same arguments as client
7854 receives from server except for ID's. ID's are mapped to correct
7855 ID entry and that is returned. Also, if channel entry is not sent
7856 by server but the notify is for channel the channel entry is sent
7857 to application (otherwise application doesn't know that it is for
7858 channel (library gets it from packet's Destination ID)).
7860 * Added silc_client_remove_from_channels into client library to
7861 remove a client from all channels it has joined to. Used when
7862 received SIGNOFF notify from server. Added also new function
7863 silc_client_replace_from_channels to replace old ID entry with
7864 new ID entry on all channels. Used when received NICK_CHANGE
7867 * Fixed ID Cache list handling in silc_idlist_get_client in
7868 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7869 to get (or query) client by ID.
7871 * Updated TODO list.
7873 * Added connection authentication status message defined by the
7874 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7875 support for these into the code in client and server side.
7877 * Added generic function silc_client_send_command to send any command
7878 with variable argument list. Application should use this function
7879 to send commands if the command functions provided by the library
7880 does not suite for the application's user interface needs.
7882 * Added new `failure' client operation. Application is notified about
7883 received failure packet if client is executing a protocol. In this
7884 case the protocol's execution has failed.
7886 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7887 is required by the protocol.
7889 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7890 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7893 * Added status flag to SilcSKE object to indicate realtime status
7894 of the SKE protocol.
7896 * Application receives now exactly same command reply arguments as
7897 the library receives from server. However, if ID is received the
7898 corresponding ID entry is returned to the application (eg. Client
7899 ID is mapped to correct SilcClientEntry entry and that is returned).
7900 Changed command_reply client operation due to this change.
7902 * Changed all ID's in commands and in command replys as ID Payloads.
7903 Change affected both client and server side codes.
7905 All ID's sent in SILC network (with execption of ID's in SILC
7906 Packet header) are sent in ID Payload to support variable length
7909 * Server now notifies nick changes and notifies all clients on
7910 the channels about the new nickname (about the new Client ID,
7913 * Implemented CMODE command to change channel modes. Supports all
7914 channel modes defined by the protocol specs except ban and invite
7915 lists. (Also, private channel key mode is supported but support for
7916 setting private channel key in client is missing, thus, this mode
7917 has no effect on client side (except that server requires that the
7918 client uses private channel key and normal channel traffic does not
7921 Also, invite mode works per se, but INVITE command does not work
7922 yet correctly, so you can set channel as invite only channel but
7923 inviting clients to the channel does not work (it is yet to be
7924 thought what's the best way to do it).
7926 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7927 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7928 Implemented CUMODE command to change user's mode on the channel.
7929 Supports all modes defined by the protocol specs.
7931 * Added NAMES command reply to return users modes on the channel.
7933 * Removed unnecessary and slow ciphers from lib/silccrypt.
7935 * Set SO_KEEPALIVE option to connection sockets by default.
7937 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7939 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7940 redefined the Notify Payload into protocol specs.
7942 * Added silc_id_payload_parse_id to get ID directly from raw
7945 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7947 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7948 accept searching by Client ID as well.
7950 * Added support for LEAVE and SIGNOFF notify types in client library.
7952 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7953 to parse ID Payload from raw data.
7955 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7957 * Added flags parameter into silc_ske_assemble_security_properties
7958 function in lib/silcske/silcske.[ch].
7960 * Changed notify client operation to fit better for notify messages
7961 sent by server. The notify payload received from server is now
7962 passed to the application (after parsing it to SilcNotifyPayload).
7963 It is application's responsibility to retrieve the arguments
7964 from the payload and show the message the way it wants. The message
7965 sent by server is implementation specific.
7967 * Changed public keys to comply with the protocol specification.
7968 Old public keys are not supported anymore and are not compatible.
7970 * Removed nickname from Channel Payload as the latest draft removed
7971 it. The client must resolve the nickname from the NAMES command
7972 reply received when it joined the channel.
7974 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7976 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7978 * Fixed some errors in protocol specification drafts.
7980 * Created lib/silccore/silcnotify.c to implement Notify Payload
7981 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7982 generic payloads described by protocol specifications. The file
7983 includes implementations for ID Payload and Argument Payload.
7985 * Changed Command Payload implementation to use the new Argument
7986 Payload. Changed command_xxxx_payload to command_payload_xxxx
7987 to comply with SILC coding conventions.
7989 * Added suppport for Argument Payload handling in Notify Payload
7990 implementation as protocol requires it. Added the new support
7991 into server and client lib as well.
7993 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7995 * Added support for multiple nicknames on same channel. [n] is
7996 added locally to the nickname if there are more than one same
7997 nicknames on the channel.
7999 * Server now sends all nicknames that matched WHOIS request.
8000 Client also shows the list received from server.
8002 * Added TOPIC command to client side. User can now set and show
8003 current topic on channel.
8005 * Added MOTD command to client and server. Also, server sends the
8006 motd when client connects to the server.
8008 * Changed version strings to comply ISO 8601.
8010 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8012 * Fixed protocol error handling in client library. It should now
8013 cope even if the SKE fails for some reason.
8015 * Made new protocol specification drafts for submitting to IETF.
8017 * Implemented TOPIC command to server in silcd/command.c.
8019 * Added two new notify types into lib/silccore/silcnotify.h:
8020 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
8021 notify nickname change and topic setting/change on a channel.
8023 * API change of command_reply operation in client library. The
8024 application gets now the status type received from server as well.
8026 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8028 * Removed the function just added to lib/silcutil/silcschedule.[ch].
8030 * Cras fixed and optimized the packet handling even further and
8031 it should work now. Minor change to the prototype of function
8032 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
8034 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8036 * Added new function into lib/silcutil/silcschedule.[ch]:
8037 silc_schedule_with_fd to select() a specified fd. The function
8038 returns after timeout expires or data arrives or goes. The
8039 function is used by packet routines to wait that all data is
8040 received from network.
8042 * Fixed data reading from network in lib/silccore/silcpacket.c.
8043 The code now assures that all data is read from the fd and then
8044 continues packet processing. This was a bug fix since the code
8045 used to drop some data in some circumstances.
8047 * Added new function into lib/silcclient/client.[ch]:
8048 silc_client_start_key_exchange to start key exchange after
8049 connection has been established to server. The code internally
8050 now uses this funtion but its main purpose was to provide it
8051 for applications that perform their own connecting. After
8052 application has created a connection it merely calls this
8053 function to start the key exchange between client and server.
8054 The library takes care of everything else after that.
8056 Updated also lib/silcclient/README to explain the usage of
8059 * Do not send to application information that connection has
8060 been established. Application gets notified it by connect
8063 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8065 * Applied cras's patch to add silc_schedule_one function. The
8066 function runs scheduler once and returns.
8068 * Fixed the scheduler after cras messed it up. The timeout
8069 handling works now as it's supposed to work.
8071 * Added into lib/silccore/ silcnotify.h to include notify
8072 message types support. Changed silc_server_send_notify*
8073 functions, in server.[ch], to support those new notify types.
8074 Added the support for the notify types into client library,
8075 as well. Added new notify client operation into ops.h in
8078 * Changed silc_server_packet_send_to_channel to send normal
8079 packets instead of just channel message packets. The function
8080 is now used to send the notify packets to channels. It is not
8081 used to send channel message packets anymore, as server never
8084 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
8085 va_arg()s as it seems to require it nowadays. I guess, if SILC
8086 is compiled with older va_arg() the new code should work anyway.
8088 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8090 * Splitted core library. Core library (lib/silccore) includes
8091 now only SILC protocol specific core (and common) components.
8092 Created new utility library (lib/silcutil) that includes more
8093 generic purpose stuff. The stuff for util library was taken
8094 from the old core library. This was minor and easy split.
8096 * Created SILC Client Library (lib/silcclient) that includes
8097 implementation of the SILC client without user interface. This
8098 was major move from silc/ directory. The code has been changed
8099 so that it is transparent towards the user interface. The
8100 silc/ directory includes now the same user interface as before
8101 and it uses the new client library. Read lib/silcclient/README.
8102 Basicly, the client library performs everything else related
8103 to SILC except user interface handling. Also, configuration
8104 files are considered to be part of user interface and library
8105 does not handle them.
8107 This change also changed a lot of structures, function naming etc.
8108 Most important change was that SilcClientWindow object was
8109 renamed to SilcClientConnection in the client library. Created
8110 also new file lib/silcclient/ops.h. Also added new files
8111 silc/local_command.[ch] and silc/client_ops.[ch].
8113 All these changes were made to make it easier for user interface
8114 designers to create what ever user interface for the SILC client
8117 It is also expected that the server will be moved to lib
8118 directory as well and SILC Server Library will be created;
8119 sometimes in the future.
8121 * Removed Local commands from lib/silccore/silccommand.h as
8122 they are application specific and new client library does not
8123 handle any of those anymore.
8125 * Several functions moved to lib/silcutil/silcutilc.[ch] from
8126 old client implementation in silc/.
8128 * Added support for callback functions in SILC_LOG_* macros.
8129 Application can now set its own callbacks that will be called
8130 instead of using the default functions that will always print
8131 the debug messages to stderr (or stdout). Also, debugging can
8132 now be disabled by setting silc_debug to FALSE and re-enabled by
8133 setting it to TRUE. Note, that logging will still work even
8134 if debugging is disabled.
8136 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
8137 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
8138 silc_log_reset_debug_callbacks.
8140 * To enable debugging in silc client one must give now -d
8141 option on command line.
8143 * Changed silc_schedule_init to automatically allocate task queues
8144 if they are not allocated before calling it.
8146 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8148 * Added GMP 3.1 into math library.
8150 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8152 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
8153 a channel in SILC network. The packet is used by servers and
8154 routers to notify other routers that user has left a channel.
8155 This little feature was missing until now. Added the feature
8156 to protocol specification as well.
8158 Added functions: silc_server_send_remove_channel_user and
8159 silc_server_remove_channel_user into server.[ch].
8161 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
8162 lib/silccore/silcpacket.h. However, they are not implemented
8165 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8167 * Fixed joining to a channel and sending channel messages
8168 between server and router. The channel message sending should
8169 now work inside a cell.
8171 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8173 * Fixed the private message sending between server and router.
8174 The private message sending should now work inside a cell.
8176 * Added silc_server_replace_id into server.[ch] to replace
8177 existing ID in the SILC network.
8179 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
8180 and silc_idlist_replace_server_id into idlist.[ch] in server.
8182 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8184 * Fixed the server to server connections. Server can again now
8185 connect to router. Router to router connections probably does
8188 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8190 * Added dynamic protocol registering support. Now protocols can
8191 registered and unregistered on the fly. Patch by cras.
8193 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8195 * Added lib/contrib directory to hold routines that some platforms
8196 don't have but are needed by SILC.
8198 * Added getopt.c, getopt1.c and getopt.h from GNU C library
8199 into lin/contrib to provide getopt() and getopt_long() for
8200 those who don't have it.
8202 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8204 * Added AWAY command to client. When away message is set and
8205 client receives a private message packet the client automatically
8206 replies to the sender with the away message.
8208 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
8209 bug seemed to be the cause of recent problems when compiling
8212 * Added version detection support to SKE protocol specification
8213 and added the new changes to the SKE implementation as well.
8214 There were other minor changes in the SKE protocol as well.
8216 Many changes in lib/silcske/silcske.[ch] and in
8217 lib/silcske/payload.[ch].
8219 * Added ^U functionality, clear input line. Patch from cras.
8221 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8223 * Mainly small bugfixes on core library. Fixed some debugging
8224 logging and buffer overflow in silclog.c.
8226 * Updated config.sub and config.guess on the distribution tree.
8228 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8230 * Added command lagging support in server. Client may execute
8231 commands now only once in two seconds.
8233 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8235 * Optimized packet reception. MAC computation and checking is now
8236 also more optimized. A lot previously duplicated code is now
8237 used as generic by both client and server.
8239 * Fixed key pair generation in clientutil.c
8241 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8243 * Added into lib/silccore/silcbufutil.[ch] new function;
8244 silc_buffer_realloc.
8246 * Moved generic packet sending/encryption functions to
8247 lib/silccore/silcpacket.[ch] from client and server. Some
8248 rewriting of the functions.
8250 * Moved all generic packet reception/decryption functions to
8251 lib/silccore/silcpacket.[ch] from client and server. The
8252 packet processing is now much cleaner in both client and server.
8253 These were major changes in both client and server.
8255 * Created many common functions in server to do packet sending.
8256 Previously code were duplicated a lot, this has been removed
8259 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8261 * Rewrote major parts of the ID cache system. Don't know
8262 whether it is better now or not but at least the API is more
8265 * Major rewrite on ID cache stuff on client because of the ID
8266 cache API changes. Added idlist.c to client.
8268 * Also major rewrite on ID cache stuff on server as well.
8269 Major rewrite of idlist.[ch]. SilcXXXList's are now named
8270 SilcXXXEntry's. We won't keep anymore idlist specific pointers
8271 in hand, instead they are all put into the ID cache system now.
8272 All server_idlist_* routines uses ID cache now instead of
8273 traversing its own lists (those lists does not exist anymore).
8274 SilcIDList though still exists. Also, SilcXXXEntry's are
8277 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8279 * Finally made the SKE implementation compliant to the protocol
8280 specification. All mp integers are now binary encoded as
8281 opposed being HEX encoded.
8283 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
8286 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
8287 functions: silc_[encode/decode]_pem. Also added function
8288 silc_encode_pem_file to PEM encode with newlines ('\n') for
8291 * SILC public keys are now encoded either PEM or binary. Same
8292 option is for private keys as well. By default private keys
8293 are binary encoded and public keys PEM encoded. Silly HEX
8294 encoding were removed.
8296 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
8297 function to create fingerprints.
8299 * Fixed a bug in SHA1; does not change the original data anymore.
8301 * Partly implemented INFO command on client and server side.
8302 Fixed CLEAR command. Changes to SERVER command; show current
8303 server(s) when giving command without arguments. Added
8304 VERSION command to client.
8306 * Added check to server that unregistered connections cannot
8307 execute commands (unless it is specificly allowed).
8309 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8311 * Fixed screen refresh.
8313 * Fixed channel joining bug from client. On some circumstances
8314 client tried to join to a channel it had already joined.
8316 * Added public key verification process into client's protocol.c.
8317 The client now verifies the public key from user and saves
8318 it into ~./silc/serverkeys/ directory.
8320 Added into: clientutil.[ch]: silc_client_verify_server_key.
8322 * Changed SKE protocol's silc_ske_initiator_finish function
8323 to accept callback function that verifies the received public
8324 key. Removed old silc_ske_verify_public_key function.
8326 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8328 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
8329 silc_pkcs_private_key[_data]_set.
8331 * Made the password and public authentication more cleaner in
8332 server's protocol.c.
8334 * Removed historic and obsolete protocol `channel_auth' from
8335 both client and server.
8337 * Removed wrong way of sending command status messages from
8338 server to client in server's command.c. The old way violated
8339 protocol specification.
8341 Changes to silccore/silccommand.[ch]: removed
8342 silc_command_encode_status_payload -> not needed anymore,
8343 changed silc_command_encode_payload_va to accept extra
8344 argument on variable argument list. The argument type must
8345 now be provided to the function. Also, added new function:
8346 silc_command_encode_reply_payload_va which is same as
8347 normal command_encode_payload_va except command status type
8348 is provided as extra argument.
8350 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8352 * Added ~./silc directory handling. The directory includes the
8353 public and private keys for the client.
8355 Added silc_client_check_silc_dir, silc_client_create_identifier
8356 and silc_client_load_keys.
8358 * Implemented SILC protocol compliant public key. Added public
8359 and private key saving to and loading from files.
8361 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
8362 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
8363 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
8364 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
8365 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
8367 Implemented: silc_pkcs_save_[public/private]_key[_data] and
8368 silc_pkcs_load_[public/private]_key.
8370 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8372 * Added silc_server_get_route (route.[ch]) to get connection
8373 data for the fastest route for given ID.
8375 * Implemented INVITE command on client and server. The command
8376 were re-defined in the SILC Protocol Specification and the
8377 implementation now complies with the specification.
8379 * Implemented PING command on client and server.
8381 * Implemented NAMES command on client and server. The server side
8382 supports currently only normal server not router server yet.
8383 Some changes to NAMES definition in SILC protocol specification.
8385 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8387 * Implemented LEAVE command on client and server.
8389 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
8390 again. This change was made to the protocol as well. Server
8391 should not violate the protocol specification anymore.
8393 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8395 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
8396 was tested. SOCKS4 was not but should work anyway.
