505 * Added SILC_PROTOCOLVERSION macro to check protocol version
506 of a socket connection. The affected file is
507 lib/silcutil/silcsockconn.h.
509 * Added better error logging in rekey protocol. Affected file
512 * Do not check public key types in SKE during rekey. Affected
513 file lib/silcske/payload.c.
515 * Fixed the rekey protocol with PFS, which was totally broken.
516 Affected file silcd/protocol.c.
518 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
520 * Some client implementations quit network by doing first LEAVE
521 and then immediately SIGNOFF (like Bombyx). We now do check
522 after a short time after LEAVE notify and check whether the
523 client is still valid after LEAVE, and if not we remove it from
524 cache. Affected file is lib/silcclient/client_notify.c.
526 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
528 * Merged version 1.1.4 of zlib. Even if it not currently in use,
529 it's good not to have security holes here.
531 * Fixed a negative refcount situtuation for the config context.
532 Affected file is silcd/serverconfig.c.
534 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
536 * ROBOdoc documented lib/silcutil/silcutil.h.
538 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
540 * Optimized even more the SilcPacketContext structure. Now
541 totally saved 16 bytes of memory per context after optimization.
542 Affected files are lib/silccore/silcpacket.[ch].
544 * Made strict checks for valid SILC IDs. Affected file is
545 lib/silccore/silcid.c.
547 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
549 * Changed the object argument for silc_cipher_register,
550 silc_hash_register, silc_hmac_register and silc_pkcs_register
551 to const. Affected files are lib/silccrypt/silccipher.[ch],
552 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
554 * Changed the silc_get_username and silc_get_real_name to
555 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
557 * Fixed the Irssi SILC Client to use the silc_get_username and
558 silc_get_real_name insted of glib routines since the glib
559 routines only corrupt stack. Fixes the Irssi SILC to work in
560 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
562 * Fixed the Irssi to not use g_get_home_dir since it crashes
563 or returns garbage on cygwin and corrupts stack. Added function
564 get_home_dir to Irssi routines. Affected files are
565 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
567 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
569 * Made some structure optimizations. SFTP memory FS MemFSEntry
570 entry structure. Optimized SilcTask structure. Optimized
571 SilcPacketContext structure.
573 Affected files lib/silcsftp/sftp_fs_memory.c,
574 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
576 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
578 * And yet again reverted back the config thing since Johnny
579 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
582 * Fixed memory leaks from config object. Affected files are
583 silcd/serverconfig.[ch].
585 * Added support for adding new connections to the server in rehash.
586 After rehash they take effect.
588 Added support for changing the maximum allowed connections in
589 rehash. The number can grow but going smaller is not supported.
591 Added function silc_server_num_sockets_by_remote to the
592 silcd/server_util.[ch].
594 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
596 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
598 * Added preliminary checking during config parsing for a valid
599 public/private key and removed further checks in the code.
600 Affected files are silcd/serverconfig.[ch], server.c.
602 * Moved functions silc_server_drop() and silc_server_daemonise()
603 from server.c to silcd.c since they are stricly related to
604 the application activity.
606 * Reverted a small part of the automatic ref/unref since
607 it caused a double unref in some situations. Affected
608 files are silcd/silcd.[ch], server.c, serverconfig.c.
610 * Added some .cvsignore files in the lib directory.
612 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
614 * Fixed silc_net_gethostbyaddr to correctly resolve by
615 address. Affected file lib/silcutil/silcnet.c.
617 * Fixed the notify relaying to client. The HMAC to be used
618 with relayed packets ws wrong and caused decryption failure
619 at the client end. Affected file is silcd/packet_receive.c.
621 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
623 * Created new branch silc_protocol_1_0_branch.
625 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
627 * Changed the silc_server_config_* routines to be SilcServer
628 independent. They are now officially application specific code
629 and not part of generic server implementation. Affected files
630 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
632 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
634 * Added automatic referencing of config context in the
635 silc_server_config_alloc, and automatic unreferencing in the
636 silc_server_config_destroy. Affected files are
637 silcd/serverconfig.[ch], silcd/silcd.c.
639 * Fixed the silc_log_quick handling in the logging routines.
640 It didn't log quickly when it was TRUE. Affected file is
641 lib/silcutil/silclog.c. Also the flush delay was set even
642 if it was 0 in config file. Affected file is
643 silcd/serverconfig.c.
645 * Added support for changing key pair of the server in rehash.
646 Affected file silcd/server.c.
648 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
650 * Fixed the TOPIC_SET notify to not cras. It changed the topic
651 too early, before getting the channel entry. Affected file
652 is silcd/packet_receive.c.
654 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
656 * Added functions silc_server_config_[ref/unref], these are used
657 to prevent that the config object is destroyed.
659 No longer directly affect global variables silc_log_quick and
660 silc_log_delay, they are first cached inside the config object
661 and then applied with silc_server_config_setlogfiles().
663 silc_server_config_set_defaults() is now internal to
664 serverconfig.c, there are no reasons to show this internal stuff
667 Affected files are silcd/serverconfig.[ch].
669 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
670 fprintf's to stderr, since some code may be executed again after
671 the server went into the background. Affected files are
674 * Added rehash support. Added function silc_server_rehash() that
675 will perform all the basic tasks of the rehashing procedure.
677 * Added command line option `-x, --hexdump'. This will enable the
678 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
679 The option `--hexdump' implies `--debug'.
681 * Fixed a bad bug in the logging APIs (silcutil library) where
682 the application would crash after calling silc_log_reset_all().
684 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
686 * Fixed the KICKED notify handling in client library to
687 correctly remove the channel and all entries from the
688 channel when I was kicked. This bug crashed the client.
690 Fixed yet another but in KICKED notify handling to remove
691 the kicked client correctly from the channel.
693 Affected file is lib/silcclient/client_notify.c.
695 * Fixed a minor bug in looking up correct client entry
696 in KICKED notify in server. Affected file is
697 silcd/packet_receive.c.
699 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
700 sources correctly to distribution. Fixes --with-gmp option.
702 * Removed the manual rehashing from ID Cache, and changed it
703 to use the SILC Hash Table's auto rehash feature. Affected
704 file is lib/silccore/silcidcache.c.
706 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
708 * Fixed a bug in the silc_client_nickname_format function that
709 handles the multiple same nickname formatting. Two clients
710 with same nickname caused problems after the first one left
711 and rejoined. It didn't format the nickname correctly.
712 Affected file is lib/silcclient/idlist.c.
714 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
716 * Don't change the topic if olod topic is same as new one.
717 Affected file is silcd/packet_receive.c.
719 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
721 * Added cross-reference support to the SILC Documentation
722 generator. All types across all HTML files are now cross-
723 referenced. Affected files util/robodoc/generator.c and
724 scripts/silcdoc/silcdoc.
726 * Added file lib/silcutil/silctypes.h to include all the
727 arithmetic type definitions and some macros. Removed
728 includes/bitmove.h and moved macros to silctypes.h.
730 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
732 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
734 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
736 * Added `type' argument to silc_id_payload_parse_id function which
737 now returns the type of the ID to the sent pointer. Affected
738 file is lib/silccore/silcid.[ch].
740 * Added check for CMODE_CHANGE notify type that mode change is
741 allowed by the sender. Affected file silcd/packet_receive.c.
743 * Added check for CUMODE_CHANGE notify type that mode change is
744 allowed by the sender. Affected file silcd/packet_receive.c.
745 Added the ID type as CUMODE_CHANGE notify type as argument
746 to the `notify' client operation. Affected files are
747 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
749 * Added function silc_client_add_server to the client library.
750 Added support for resolving also channel and server info when
751 received unknown entity in notify packet. Affected files are
752 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
754 * Added function silc_command_get_status to return the command
755 status from the command reply's argument payload. Affected files
756 are lib/silccore/silccommand.[ch].
758 * Added check for KICKED notify type that the kicking is
759 allowed by the client. Affected file silcd/packet_receive.c.
761 * Created function silc_get_input which can be used to get input
762 (echo on or off) from user on command line. Affected files are
763 lib/silcutil/silcutil.[ch].
765 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
767 * Optimized silc_server_packet_relay_to_channel function.
768 Added new function silc_channel_message_payload_encrypt which
769 can be called directly if channel message payload needs to
770 be encrypted and is already encoded (no need to call _encode
771 function). Packet relaying is now done by router without any
772 extra memory allocations. Affected files are
773 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
776 * Fixed the INVITE notify handling. It took wrong arguments
777 as invite list and invite delete. Affected file is
778 silcd/packet_receive.c.
780 * Added check for TOPIC_SET notify type that the topic change is
781 allowed by the client. Affected file silcd/packet_receive.c.
783 * Added check for INVITE notify type that inviting is allowed by
784 the client. Affected file silcd/packet_receive.c.
786 * Changed the silc_server_client_on_channel to return the
787 SilcChannelClientEntry as well. Moved the function
788 silc_server_check_cmode_rights to server_util.[ch].
789 Affected files are silcd/server_util.[ch], silcd/command.c.
791 * Added function silc_server_check_umode_rights to check whether
792 changing client's user mode is allowed. Added check for
793 UMODE_CHANGE notify type that the umode change is allowed
794 by the client. Affected files are silcd/server_util.[ch],
795 silcd/packet_receive.c and silcd/command.c.
797 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
799 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
800 ID length. It ignored that ID can be IPv6 based as well.
801 Affected file lib/silccore/silcpacket.h.
803 * Fixed the silc_id_id2str and silc_id_str2id to take the
804 IPv6 address offset's into consideration. Affecte file is
805 lib/silccore/silcid.c.
807 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
809 * Fixed the internal Unix scheduler functions to check for
810 NULL context they may receive. The affected file is
811 lib/silcutil/unix/silcunixschedule.c.
813 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
815 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
816 can specify different directory with --home command line
817 parameter. Affected files irssi/src/silc/core/client_ops.c,
820 * SILC-specific commands aren't now executed if the active server
821 isn't of SILC-type, so there won't be problems with having
822 IRC and SILC protocol support in same client. Affected files
823 irssi/src/silc/core/silc-channels.c, silc-servers.c,
826 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
828 * Improved the signal support in SILC Schedule. Added new
829 function silc_schedule_signal_call which is used by application
830 to mark a signal to be called. It is now safe to perform
831 any kind of tasks in signal callbacks since it is guaranteed
832 that the application specified signal callback is called
833 after the signal is over. Affected files are
834 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
836 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
838 * Added `name' field to SilcChannelPrivateKey to represent
839 application given name for the key. Moved also the context from
840 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
841 Added the `name' argument also to the function
842 silc_client_add_channel_private_key.
844 Added function silc_client_current_channel_private_key to set the
845 current channel private key in use.
847 Added "change" command to KEY command which can be used to change
848 the current channel private key. Bound the command also to
851 Also affected files lib/silcclient/client_channel.c,
852 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
854 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
856 * Added silc_rng_get_byte_fast function in to the
857 lib/silccrypt/silcrng.[ch].
859 * Changed the interface of silc_packet_assemble and the
860 silc_packet_send_prepare. If silc_packet_assmble is now
861 called the application does not call silc_packet_send_prepare
862 because the library will call it automatically. These
863 interfaces now also return a reference to the outgoing buffer
864 which includes the assembled packet, which the application can
865 use to encrypt the packet.
867 Affected files are lib/silccore/silcpacket.[ch],
868 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
869 silcd/packet_send.c, server_backup.c and packet_receive.c.
871 * Fixed a packet sending bug on very high load, where outgoing
872 packet queue wasn't handled correctly and packets got corrupted.
873 Affected files are lib/silcutil/*/silc*sockconn.c,
874 lib/silcclient/client.c and silcd/server.c.
876 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
878 * Added macro SILC_PACKET_DATALEN which can be used during
879 packet assembling to check whether the data to be added to
880 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
881 len is truncated until it fits it.
883 Added checks for maximum length of channel message payload and
884 private message payload also.
886 Added checks for maximum packet length in server and in
889 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
890 lib/silcclient/client.c, lib/silccore/silcchannel.c and
891 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
892 lib/silcclient/client_prvmsg.c.
894 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
896 * Added silc_server_packet_queue_purge call to the
897 silc_server_disconnect_remote to assure that all data in the
898 queue before disconnecting is sent to the network. Affected
901 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
903 * Added the deleting of server's own ID cache entry to the
904 silc_server_free function. Free also everything else that
905 has been allocated in silc_server_init. The affected file
908 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
910 * Added functions silc_parse_version_string, silc_version_to_num,
911 and silc_ske_parse_version to parse SILC protocol style version
912 strings. Affected files lib/silcutil/silcutil.[ch] and
913 lib/silcske/silcske.[ch].
915 * Added new configuration params: version_protocol, version_software
916 and version_software_vendor to specify what version the remote
917 host must at least be to be able to connect to server. The vendor
918 string can be regex matched too. Added new function
919 silc_server_connection_allowed to check maximum number of allowed
920 connections, and allowed versions for incoming connections.
921 Affected files are silcd/server.c, server_util.[ch] and
924 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
926 * Added preliminary support for signals in scheduler. The
927 signals we care about are now blocked always when the scheduler
928 is locked. This way we can synchronise the use of signal with
929 scheduler. It is guaranteed that when signal occurs the scheduler
930 is not locked, and thus new tasks can be safely added to the
933 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
934 to silc_schedule_internal_init and silc_schedule_internal_uninit.
935 Added new platform specific routines
936 silc_schedule_internal_signals_[un]block and
937 silc_schedule_internal_signal_[un]register.
939 Added new functions to SILC Schedule API:
940 silc_schedule_signal_[un]register. Each signal that application
941 is going to use should be registered to the scheduler.
943 Affected files are lib/silcutil/silcschedule.[ch],
944 lib/silcutil/*/silc*schedule.c.
946 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
948 * Check for unauthenticated client and server in the
949 silc_server_new_client and silc_server_new_server functions.
950 Affected file silcd/packet_receive.c.
952 * Added function silc_string_is_ascii to check whether given
953 string is 7-bit ASCII string. Affected files are
954 lib/silcutil/silcutil.[ch].
956 * Added function silc_id_is_valid_server_id into the
957 silcd/serverid.c and added checking for valid Server ID's in
958 silc_server_new_server. The Server ID must always be based
959 on the server's public IP address.
961 * Added logging of DISCONNECT packet message in the server.
962 Affected file silcd/server.c.
964 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
966 * Changed all library interfaces that use Global RNG to also
967 accept SilcRng as argument. Affected files are
968 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
969 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
970 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
971 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
974 * Added function silc_pkcs_generate_key to the
975 lib/silccrypt/silcpkcs.[ch] for applications so that they
976 don't need to do pkcs->pkcs->init calls anymore.
978 * Remove SilcSocketConnection from the SFTP API since it really
979 wasn't needed there. The application has the information
980 saved in its contexts anyway and the SFTP layer doesn't need
981 know about it. Affected files lib/silcsft/silcsftp.h and
982 lib/silcsftp/sftp_[server/client].c.
984 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
985 The SilcSimContext is not SilcSim.
987 * Fixed possible buffer overflows in silc_id_render in the
988 lib/silcutil/silcutil.c.
990 * On EPOC the global crypto module lists are not used at all
991 in the crypto library. Added support for using the constant
992 algorithm list on EPOC. Affected files are
993 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
996 * Fixed the handling of third parameter of KICKED notify, since
997 it was mistakenly updated to SILC Protocol 1.0 even though it
998 is to be included in 1.1. Since it is not in 1.0 it is not
999 mandatory, and this fix now handles it only if it is provided,
1000 and it is not error if it is not provided. Affected file
1001 lib/silcclient/client_notify.c.
1003 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1005 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
1006 client. Affected file irssi/src/silc/core/client_ops.c.
1008 * Merged with Irssi 0.8.4 from irssi.org CVS.
1010 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1012 * Check for valid socket connection in client entries before
1013 sending any messages. Fixes a crash, but doesn't fix some
1014 other underlaying bug that is lurking there. Affected
1015 file silcd/packet_send.c.
1017 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
1019 * $usermode, $cumode and $cumode_space expandos shouldn't do
1020 anything with non-SILC server records. Affected file
1021 irssi/src/silc/core/silc-expandos.c
1023 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1040 file lib/silcutil/silcutil.[ch].
1042 * Added support for specifying multiple public keys for Client
1043 connection section in server configuration file. This makes it
1044 possible to accept multiple public keys from same host, or to
1045 make a section that accepts any incoming host, and have the
1046 accepted public keys listed in the section.
1048 Added functions silc_sever_[find/get]_public_key, added the
1049 support for this actually to all connection sections but only
1050 the Client section is currently allowed to specify multiple

1161 old name went against naming convention. Applications now
1162 include "silcclient.h" instead of "clientlibincludes.h".
1163 Removed includes/clientlibincludes.h, it is redundant now.
1165 * Renamed includes/version.h to silcversion.h.
1167 * Added really preliminary support for OS/2 into the util
1168 library. Only thread & mutex API is implemented, others
1169 are still to be implemented. Created the lib/silcutil/os2/

1203 * Added `user_count' to the SilcChannelEntry which now tells the
1204 number of users on the channel. The user count is now saved
1205 in normal server of global channels as well. Affected files
1206 silcd/server.c, idlist.h, packet_receive.c and command.c.
1208 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
1209 include file utility functions.

1225 the SKE interface a bit.
1227 * Fixed padding problem in PKCS#1. The padding was not actually
1228 random since the random number generator was used incorrectly.
1229 This security bug affects only when encrypting with PKCS#1, and
1230 it is not currently used at all in SILC. SILC only use signing
1231 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.

1295 irssi/src/fe-text/silc.c.
1297 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1299 * Added new configuration options and blocks:
1300 keepalive_secs, reconnect_count, reconnect_interval,
1301 reconnect_interval_max, reconnect_keep_trying and

1316 the connection configuration object from the SilcServerConnection
1317 object instead of finding it during the connecting phase.
1318 Added the configuration object to SilcServerConnection struct.
1319 Affected files silcd/server_internal.h, server.c.
1321 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1323 * Add the client on channel after it was resolved at the
1324 channel message receiving, and it was not already on the
1325 channel. Affected file lib/silcclient/client_channel.c.

1347 public key is set. If not set, public key is preferred.
1348 This has effect only when being initiator (responder will try
1351 Added support for authentication with passphrase and public key
1352 at the same time. The passphrase is tried first always since
1353 it is faster to check.
1355 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
1357 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

1403 * Fixed the file transfer's key agreement payload to include
1404 zero port also if the hostname is NULL because it could not
1407 Call file transfer monitor callback now also if error occurs
1408 during key agreement protocol.
1410 Changed the silc_client_file_send interface to return the
1411 SilcClientFileError instead of session id. The session ID
1412 is returned into pointer provided as argument.

1431 * Fixed the channel message payload decryption in the function
1432 silc_channel_message_payload_decrypt to not modify the original
1433 buffer before it is verified that the message decrypted
1434 correctly. Otherwise, next time it is called with correct
1435 channel key it won't encrypt since the payload is corrupted.
1436 Affected file lib/silccore/silcchannel.c.
1438 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1451 the table with foreach callback. The current entry may
1452 become invalid in the callback but it was referenced after
1453 the callback returned.
1455 Do not allow auto rehashing of hash table during the
1456 silc_hash_table_foreach operation, for same reasons as it is
1457 not allowed for SilcHashTableList. Affected files are
1458 lib/silcutil/silchashtable.[ch].
1460 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>

1484 * Fixed a bug in hash table tarversing. While the hash table
1485 is traversed with SilcHashTableList the table must not be
1486 rehashed. It is now guaranteed that auto rehashable tables
1487 are not rehashed while tarversing the list. Also defined that
1488 silc_hash_table_rehash must not be called while tarversing
1489 the table. Added function silc_hash_table_list_reset that must
1490 be called after the tarversing is over. The affected files are
1491 lib/silcutil/silchashtable.[ch].
1493 * Changed all hash table traversing to call the new
1494 silc_hash_table_list_reset in server and in client library.
1496 * Added function silc_client_on_channel to return the
1497 SilcChannelUser entry if the specified client entry is joined
1498 on the specified channel. This is exported to application as
1499 well. Affected files lib/silcclient/client_channel.c, silcapi.h.

1507 * Fixed the WHOWAS command's reply sending to support the
1508 lists correctly. Affected file silcd/command.c.
1510 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1512 * When sending JOIN command to router for processing the
1513 sender's old command identifier was not saved back to the
1514 sender's command context, fixed now. The affected file is
1517 * Create the key in JOIN command of the router did not return
1518 the channel key, added check for this. Affected file is
1521 * Fixed a channel ID update bug in JOIN command reply. Do
1522 not directly upgrade the ID but call the function
1523 silc_idlist_replace_channel_id if the ID was changed.
1524 Affected file silcd/command_reply.c.
1526 * Fixed memory leaks from command calling if it would fail.
1527 Affected file silcd/command.c.

1551 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1553 * Fixed memory leaks in silc_server_create_new_channel*
1554 functions. Affected file silcd/server.c.
1556 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
1557 which ID was changed. This way the router will send the
1558 user list for the channel again, and server won't be in
1559 desync in some rare circumstances. Affected file is
1560 silcd/packet_receive.c.
1562 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1564 * Check for NULL socket pointer in the function
1565 silc_server_packet_send_to_channel_real. Affected file
1566 silcd/packet_send.c.
1568 * Fixed the BAN notify handling to correctly remove ban
1569 list. Affected file silcd/packet_receive.c.
1571 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1573 * Fixed some header addition to Toolkit distribution in
1574 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
1576 * Added lib/silcclient/client_ops_example.h as an template
1577 file for application programmers to quickly start using
1578 the SilcClientOperation functions in their application.
1579 Updated the lib/silcclient/README as well to tell about this
1580 nice file made available.
1582 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1584 * Call silc_server_remove_from_channels when removing client
1585 entry when NO_SUCH_CLIENT_ID was received. Affected file
1586 is silcd/command_reply.c.
1588 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1590 * Added server & router operator statistics updating. Affected
1591 file silcd/packet_receive.c and silcd/command.c.
1593 * Fixed the SERVER_SIGNOFF notify handling on normal server
1594 not to save the history information for clients. Same was
1595 fixed earlier in remove_clients_by_server function, but not
1596 here. Affected file silcd/packet_receive.c.
1598 * Raised the default connection-retry count from 4 to 7 in
1599 server. Affected file silcd/server.h.
1601 * Cancel any possible reconnect timeouts when we start the
1602 key exchange. Affected file silcd/server.c.
1604 * Do not reconnect on connection failure when SCONNECT was
1605 given. Affected files silcd/server.[ch].
1607 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1609 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
1611 * Fixed the NICK command to always give the unformatted
1612 nickname to the one giving the NICK command. If unformatted
1613 nickname is cached already it will be formatted and the
1614 local entry will always get the unformatted nickname.
1615 Affected file lib/silcclient/idlist.c.
1617 * Fixed some double frees from client library commands.
1618 Affected file is lib/silcclient/command.c.
1620 * Fixed CUMODE command in server to assure that no one can
1621 change founder's mode than the founder itself, there was a
1622 little bug. Affected file silcd/command.c.
1624 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1626 * Removed the SilcClientCommandDestructor from the client
1627 libary, it is not needed anymore. Affected files are
1628 lib/silcclient/silcapi.h, command[_reply].[ch],
1629 client_notify, idlist.c.
1631 * Fixed GETKEY command to first resolve client, and then
1632 resolve the server only if the client was not found, instead
1633 of resolving both at the same time. Affected file is
1634 lib/silcclient/command.c.
1636 * Added silc_client_start_key_exchange_cb and lookup the
1637 remote hostname and IP address before starting the key
1638 exchange with server. The affected file is
1639 lib/silcclient/client.c.
1641 * The server's public key is now saved using the IP address
1642 of the server and not the servername for the filename.
1643 The hostname public key filename is checked as an fall back
1644 method if the IP address based filename is not found.
1646 Fixed the GETKEY command to save the fetched server key
1647 in correct filename.
1649 Print the remote server's hostname now when new key is
1650 received during connection process. Affected file is
1651 irssi/src/silc/core/client_ops.c.
1653 * Return always our own public key to the client if it asks
1654 for it with GETKEY command. Affected file silcd/command.c.
1656 * Removed the use_auto_addr variable from default config
1657 file since it was in wrong section. Affected file is
1660 * Fixed TOPIC_CHANGE notification to not route it when it
1661 was sent using silc_server_send_notify_to_channel function.
1662 Affected file silcd/command.c.
1664 * Fixed silc_server_send_notify_kicked to send the kicker's
1665 Client ID also, it was missing. Affected files are
1666 silcd/command.c, silcd/packet_send.[ch].
1668 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1670 * Do not save client history information in SERVER_SIGNOFF.
1671 Fixes the bug in normal server that it does not detect
1672 the client becoming valid after the server becomes back
1673 online. Affected file silcd/server_util.c.
1675 * Added `sock_error' field into the SilcSocketConnection
1676 context. When error occurs during socket operation (read
1677 or write) the error is saved. Added also new function
1678 silc_socket_get_error to return human readable socket error
1679 message. Affected files are lib/silcutil/silcsockconn.[ch],
1680 lib/silcutil/unix/silcunixsockconn.c, and
1681 lib/silcutil/win32/silcwin32sockconn.c.
1683 * The server now prints the socket error message in the
1684 signoff for client. Affected file silcd/server.c.
1686 * Fixed the `created' channel information sending from router
1687 to server in JOIN command. Checks now whether the channel
1688 really was created or not and set it according that.
1690 Fixed the JOIN command to use the client entry's current
1691 ID during the joining procedure instead of the one it sent
1692 in the command (it is checked though), since it can change
1693 between the packet processing and command processing, and
1694 would just case unnecessary pain in the client end. Affected
1695 file silcd/command.c.
1697 * Fixed a channel key payload sending to use correct channel
1698 ID when the server was forced to change the channel's ID by
1699 router. Router sent the key payload with the old Channel ID.
1700 Affected file silcd/packet_receive.c.
1702 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1704 * Call silc_server_save_channel_key only if the key payload
1705 was provided in the JOIN command's command reply. Affected
1706 file silcd/command_reply.c.
1708 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1710 * Fixed silc_mp_sizeinbase to return the value correctly with
1711 MPI. Affected file lib/silcmath/mp_mpi.c.
1713 * Fixed the stop_server signal to correctly stop the scheduler
1714 and gracefully stop the server when SIGTERM or SIGINT signals
1715 are received. Affected file silcd/silcd.c.
1717 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1719 * Simple handling of TERM and HUP signals. Also added some log
1720 flushing call around. Affected file is
1723 * Fixed small bugs in silclog.c. Now buffering output will take
1724 effect after 10 seconds since startup: This will ensure that
1725 no important startup messages are lost. Also output redirection
1726 will preserve original format ([Date] [Type] message).
1727 Affected file is lib/silcutil/silclog.c.
1729 * Added two options to the config file, in the logging section:
1730 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1731 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1733 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1735 * Do not print the warning about log files not being initialized
1736 more than once to avoid excess logging. Affected file is
1737 lib/silcutil/silclog.c.
1739 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1740 the SIM copying in make install in Makefile.am.pre.
1742 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1744 * Rewritten silclog APIs. Globally interesting changes follows:
1745 silc_log_set_files() changed to silc_log_set_file().
1746 silc_log_set_callbacks() changed to silc_log_set_callback().
1747 ROBOdoc documented silclog header file.
1748 SilcLogCb now returns bool to wether inihibit the default
1749 handler or not (to keep the old behaviour return always TRUE).
1750 The new APIs should also fix the problem of the
1751 silcd_error.log file that was written in the current directory.
1754 Log files streams will remain opened after silc_log_set_file()
1755 call, means less CPU usage notably on high traffic servers.
1756 File streams are now full buffered, and flushed to the disk
1757 every 5 minutes, lesses HD activity and CPU usage.
1758 Messages can be redirected, allowing admins to configure
1759 one single logfile for all server messages.
1760 the silc_log_quick global variable to activate fast-logging.
1761 Affected files lib/silcutil/silclog.[ch]
1763 * Changed some code to conform new silclog APIs. Affected
1764 files are doc/example_silcd.conf.in, silcd/server.c
1765 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1768 * Fixed a memory leak that could occur in some situations.
1769 Affected file silcd/serverconfig.c.
1771 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1773 * Added the silc_client_del_client to remove the client from
1774 all channels as well. Affected file lib/silcclient/idlist.c.
1776 * Fixed the client library to correctly remove the client
1777 from all channels when the client entry is being destroyed.
1778 Affected file lib/silcclient/client_notify.c, command.c.
1780 * Added auto-nicking support to the client library. If the
1781 applicatio now sets client->nickname it will be sent to the
1782 server after connecting by the library. This way for example
1783 SILCNICK (or IRCNICK) environment variables will have effect
1784 and always change the nickname automatically to whatever
1785 it is wanted. Affected file lib/silcclient/client.[ch].
1787 * Renamed silc_server_command_bad_chars to the
1788 silc_server_name_bad_chars and moved it to the
1789 silcd/server_util.[ch]. Added also new function
1790 silc_server_name_modify_bad to return nickname that
1791 includes bad characters as new nickname without those
1792 bad characters. This check and modify is now used in
1793 silc_server_new_client when the username is initially set
1794 as nickname, so it must be checked to be valid nickname.
1795 Affected file silcd/packet_receive.c.
1797 * The nickname length is now taken from the packet for real
1798 and not trusted to strlen() since it clearly can return
1799 wrong length for nickname including bad characters. This
1800 also applies to channel names. Affected file silcd/command.c.
1802 * Removed the lib/silcsilm/modules directory. Modules are now
1803 compiled into the lib/silcsim. Fixed the copying of the
1804 modules to follow symbolic links in Makefile.am.pre.
1806 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1808 * Fixed silc_string_regexify list creation. Fixes bugs with
1809 BAN and INVITE commands in server. The affected file is
1810 lib/silcutil/unix/silcunixutil.c.
1812 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1814 * Removed the command destructor entirely from the server's
1815 command and command reply routines. It is not needed, and
1816 its usage was buggy and caused crashes. Affected files are
1817 silcd/command[_reply].[ch].
1819 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1821 * Cancel protocol and NULL sock->protocol if timeout
1822 occurred during protocol. Affected file silcd/server.c.
1824 * Cancel protocol timeouts always before calling the final
1825 callback, to assure that after final callback is called
1826 no other state will be called for the protocol anymore.
1827 Affected file silcd/protocol.c.
1829 * Print error log if incoming connection configuration could
1830 not be found. Affected file silcd/server.c.
1832 * Fixed JOIN command to correctly save the founder mode
1833 to the client on normal SILC server, when the channel
1834 was created by the router. Affected file silcd/command.c.
1836 * Fixed LIST command (hopefully) to send correct reply
1837 packets. Affected file silcd/command.c.
1839 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1841 * The silc_packet_receive_process now returns FALSE if the
1842 read data was invalid packet, and TRUE if it was ok.
1844 The server now checks that if unauthenticated connection
1845 sends data and its processing fails the server will close
1846 the connection since it could be a malicious flooder.
1848 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1850 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1852 * Make sure the warning about error opening a log file is
1853 printed only once and not everytime it fails (produces
1854 too much useless log). Affected file lib/silcutil/silclog.c.
1856 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1858 * Made the silc_server_daemonise() function more readable.
1859 Affected file silcd/server.c.
1861 * Pid file is now optional, the user may comment it out from
1862 the config file. Removed define SILC_SERVER_PID_FILE, we
1863 don't need a default any longer. Affected file
1864 configure.in.pre, lib/Makefile.am.pre.
1866 * Make some use of the pid file. The server now dies at startup
1867 if it detects a valid pid file on his path. The server would
1868 die anyway in this circumstance, because of the bind() failure.
1869 Affected file silcd/silcd.c.
1871 * No longer compiling lib/dotconf.
1873 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1875 * Fixed JOIN command parsing not to crash. Affected file
1876 lib/silcclient/command.c.
1878 * Fied the NICK_CHANGE notify to add the new client entry
1879 even it is resolved. This removes an <[unknown]> nick
1880 thingy bug in the client. Affected file is
1881 lib/silcclient/client_notify.c.
1883 * Do not try to allocate 0 bytes (efence does not like it)
1884 in lib/silccore/silccomand.c when encoding payload.
1886 * Do not take IRCNICK as nickname in Irssi SILC client since
1887 it is not possible to set nickname before hand connecting
1888 the server (TODO has an entry about adding auto-nicking
1891 * Changed the silc_server_command_pending to check whether
1892 there already exists an pending entry with the specified
1893 command, command identifier and pending callback. This is
1894 to fix IDENTIFY and WHOIS related crashes that may register
1895 multiple pending commands with same identifier. Affected
1896 file silcd/command.c.
1898 * Fixed the server to reconnect to the router even if it
1899 was already reconnecting and EOF was received. This to
1900 fix a possibility that the server wouldn't ever try to
1901 auto-reconnect to the router. Affected file silcd/server.c.
1903 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1905 * Fixed the server's password authentication to use the
1906 length of the locally saved password, and not the one
1907 sent in the packet. Affected file silcd/protocol.c.
1909 * Fixed same password authentication problem in the
1910 Authentication Payload handling routines in
1911 lib/silccore/silcauth.c.
1913 * Yet another password authentication problem fixed with
1914 channel password handling in silcd/command.c.
1916 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1918 * If first character of string in silc_parse_userfqdn is '@'
1919 then do not parse it. Affected file is
1920 lib/silcutil/silcutil.c.
1922 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1924 * Fixed minor bug in IDENTIFY command reply sending, which
1925 caused various weird problems during JOIN when it was
1926 resolving names for users. Affected file silcd/command.c.
1928 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1930 * Fixed the IDENTIFY command reply sending to chech better valid
1931 clients. It was possible to send incomplete list of replies.
1932 Affected file silcd/command.c.
1934 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1936 * Added silc_client_command[s]_[un]register functions now to
1937 dynamically register the commands in client library. Removed
1938 the static table of commands. This allows the client library
1939 to call commands without causing the application to know about
1940 what commands library has called.
1942 Removed the INFO command reply kludge to detect when the command
1943 was called by library. Now library use its own command reply
1944 function for INFO command.
1946 Added function silc_client_command_call to call a command.
1947 Application can use it to call command, not access the structure
1950 Now all commands that are sent by the client library (not
1951 explicitly sent by application) use own command reply functions.
1953 Affected files around lib/silcclient/ and in
1954 irssi/src/silc/core/.
1956 * Fixed the WHOIS command reply sending to chech better valid
1957 clients. It was possible to send incomplete list of replies.
1959 Fixed the WHOIS and IDENTIFY to send the request to router
1960 if normal server did not do it and did not find any results.
1962 Affected file silcd/command.c.
1964 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1966 * Moved the internal data from SilcClient context into its
1967 own file, not accesible to application. Affected files
1968 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1969 and other files in client library.
1971 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1973 * Added doc/examples installation target in Makefile.am.pre.
1976 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1978 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1979 commands the found client entry will be removed from the
1980 cache, after notifying application about the error. Affected
1981 file lib/silcclient/command_reply.c.
1983 * Changed the /MSG to check for exact nickname user gave, and
1984 not let `nick' match `nick@host' if it is only one found. Now,
1985 user must type the exact nickname (like nick@host2) even if
1986 there are no more than one same nicks found. This is to avoid
1987 a possibility of sending nickname to wrong nickname since
1988 `nick' could match `nick@host'. Affected file is
1989 irssi/src/core/silc-servers.c.
1991 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1993 * Do not print "you are now server operator" or similar when
1994 giving /away command. Affected files are
1995 irssi/src/silc/core/client_ops.c, silc-servers.h.
1997 * Made the silc_server_command_pending_error_check to send
1998 the same command reply payload it received back to the
1999 original sender of the command. This way all arguments
2000 that was received by the server will be received by the
2001 client too. Affected file silcd/command.c.
2003 * Added the silc_idcache_add to return the created cache entry
2004 to a pointer. Affected file lib/silccore/silcidcache.[ch].
2006 * Add global clients to expire if they are not on any channel.
2007 This is because normal server will never know if they signoff
2008 if they are not on any channel. The cache expiry will take
2009 case of these entries. This is done by normal servers only.
2010 The affected files are silcd/command_reply.c,
2011 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
2013 * If server receives invalid ID notification for WHOIS or
2014 IDENTIFY and the ID exists in the lists, it is removed.
2015 Affected file silcd/command_reply.c.
2017 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
2018 in client then client entry that it matches is searched and
2019 the nickname is printed on the screen for user. Affected
2020 file irssi/src/silc/core/client_ops.c.
2022 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2024 * Use cache entry expire time in the LIST command reply to
2025 purge old entries from the cache after the LIST command
2026 reply has been received. This way we don't have non-existent
2027 entries in the cache for too long. Affected file is
2028 silcd/command_reply.c.
2030 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2032 * If we are normal server, and we've not resolved client info
2033 in WHOIS or IDENTIFY from router, and it is global client,
2034 we'll check whether it is on some channel. If it is not
2035 then we cannot be sure about its validity and will resolve it
2036 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
2037 file silcd/command.c.
2039 * Search channel by name (if possible) rather than by ID
2040 in IDENTIFY command's command reply. Affected file is
2041 silcd/command_reply.c.
2043 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2045 * Distribute to the channel passphrase in CMODE_CHANGE notify.
2046 Updated specs and implemented it. Affected file silcd/command.c,
2047 silcd/packet_send.c and silcd/packet_receive.c.
2049 * Implemented the <founder auth> payload handling in the JOIN
2050 command. If provided all conditions for channel joining
2051 except requirement to provide correct passphrase can be
2052 overrided by the channel founder. Updated the protocol specs.
2053 Affected file silcd/command.c.
2055 Added support for founder auth in JOIN command in client
2056 library. Fixed the parsing of the JOIN command now to support
2057 all options as they should be. The affected file is
2058 lib/silcclient/command.c.
2060 * Optimized the WHOIS and IDENTIFY commands to send the request
2061 to router only if it includes nicknames or other names. If
2062 they include only IDs then check the local cache first before
2063 routing. Affected file is silcd/command.c.
2065 * Added channels topic announcements. Affected file is
2066 silcd/packet_receive.c and silcd/server.c.
2068 * Fixed the silc_server_send_notify_topic_set to really destine
2069 the packet to channel. Affected file silcd/packet_send.c.
2071 * Fixed a crash in CHANNEL_CHANGE notify handling in the client

2092 bit changed the interface for better.
2094 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2096 * Update the client entry context in the ID cache after
2097 nick change. Affected file lib/silcclient/command.c.
2098 Fixes the CUMODE command when regaining founder privileges,
2099 and a little WHOIS problem.
2101 * Fixed silc_net_gethostbyname to correctly call the
2102 inet_ntop. Affected file lib/silcutil/silcnet.c.
2104 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2106 * Added IPv6 support checking to the configure.in.pre, added
2107 also --enable-ipv6 option to override the check. Affected
2108 file configure.in.pre.
2110 * The silc_thread_create now calls the start function
2111 directly if threads support is not compiled in. Removes
2112 ugly #ifdef's from generic code. Affected files are
2113 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
2115 * Added silc_net_gethostby[name/addr]_async to asynchronously

2132 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2134 * Fixed LIST command reply sending in server. Affected file
2137 * Server now sends the kicker's client ID in the KICK notify
2138 to the kicked client. Affected file silcd/command.c.
2140 * The client library now parses the kickers client ID and
2141 UI displays it. Affected files lib/silcclient/client_notify.c
2142 and irssi/src/silc/core/silc-channels.c, module-formats.c.
2144 * Made all payload parsing function prototypes consistent.
2145 They all take now const unsigned char * and uint32 pair as
2146 the payload data instead of SilcBuffer. Changes all around
2147 the source tree. Other unsigned char* -> const unsigned char*
2148 changes around the tree as well.
2150 * Optimized SFTP client and server packet sending not to
2151 allocate new buffer for each packet but to recycle the
2152 first allocated buffer. Affected files are
2153 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
2155 * Optimized the SFTP client to use SilcList instead of
2156 SilcDList for requests, because it is faster. Affected file
2157 is lib/silcsftp/sftp_client.c.
2159 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
2160 into lib/silccore/silcid.[ch].
2162 Renamed silcpayload.[ch] into silcargument.[ch].
2164 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2166 * If client entry is deleted with active key agreement
2167 session, abort the session.
2169 The silc_client_abort_key_agreement now calls the completion
2170 callback with new SILC_KEY_AGREEMENT_ABORTED status.
2172 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
2175 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2177 * Don't use __restrict in older GCC's. Affected file is
2178 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
2180 * silc_net_localhost now attempts to reverse lookup the
2181 IP/hostname. Affected file lib/silcutil/silcnet.c.
2183 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
2184 command. It can be used to gain founder privileges at
2185 the same time when joining the channel.
2187 Defined that the SILC_NOTIFY_TYPE_KICKED send the
2188 kicker's client ID as well. Updated protocol specs.
2190 Defined that the server must send SILC_COMMAND_IDENTIFY
2191 command reply with error status to client who sent
2192 private message with invalid client ID.
2194 Updated the protocol specification.
2196 * Added silc_server_send_command_reply to send any
2197 command reply. Affected file silcd/packet_send.[ch].
2199 * Added silc_id_payload_encode_data to encode ID payload
2200 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
2202 * The server now send IDENTIFY command reply with error
2203 status if client ID in private message is invalid. Affected
2204 file silcd/packet_receive.c.
2206 * Save the server key file with server's IP address in
2207 the filename instead of hostname. The affected file is
2208 irssi/src/silc/core/client_ops.c.
2210 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2212 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
2215 * Added libtool support for compiling shared objects in
2216 lib/silcsim. Affected file configure.in.pre and
2217 lib/silcsim/Makefile.am. Original patch by cras.
2219 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2221 * Pid file configuration, and server's config file fixes
2222 patch by toma. Updated CREDITS file.
2224 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2226 * Fixed silc_client_channel_message to not try to decrypt
2227 the message twice if it resolved the destination client
2228 information. This could cause of dropping one channel
2229 message. Affected file lib/silcclient/client_channel.c.
2231 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2233 * Added silc_client_run_one into lib/silcclient/silcapi.h and
2234 lib/silcclient/client.c. This function is used when the SILC
2235 Client is run under some other scheduler, or event loop or
2236 main loop. On GUI applications, for example this may be
2237 desired to used to run the client under the GUI application's
2238 main loop. Typically the GUI application would register an
2239 idle task that calls this function multiple times in a second
2240 to quickly process the SILC specific data.
2242 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2244 * Fixed silc_server_drop() for dropping the supplementary
2245 groups as well, this could cause a security hole on some
2248 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2250 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
2253 * Write PID file after dropping privileges. Added -F option
2254 to run server on foreground. A patch by debolaz.
2255 Affected files silcd/server.c, silcd/silcd.c.
2257 * Fixed MOTD to return the MOTD file server name. Affected
2258 file silcd/command.c.
2260 * Added INFO command reply handling to the Irssi SILC Client.
2261 Affected file irssi/src/silc/core/client_ops.c.
2263 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2265 * Fixed the silc_idcache_list_* routines to really support
2266 the dynamic list. Fixes a crash. Affected file is
2267 lib/silccore/silcidcache.c.
2269 * Fixed the LIST command reply to really call LIST command's
2270 pending callbacks. Affected file silcd/command_reply.c.
2272 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2274 * Update conn->local_entry->nickname after giving NICK
2275 command. Affected file lib/silcclient/command.c.
2277 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
2279 * Added the [pid] option to the silcd configuration file
2281 Affected files: serverconfig.[ch] and silcd.c
2283 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2285 * Save fingerprint in WHOIS command reply in server.
2286 Affected file silcd/command_reply.c.
2288 * Fixed NICK commands pending callback registration.
2289 Affected file lib/silcclient/command.c.
2291 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2293 * Use ++server->cmd_ident when sending commands in server,
2294 instead of random number. Affected file silcd/command.c.
2296 * Fixed GETKEY command reply to call actually GETKEY pending
2297 command callbacks. Affected file silcd/command_reply.c.
2299 * A bit stricter check for nicknames. Check for same nickname
2300 in NICK command also. Affected file silcd/command.c.
2302 * Do not call INFO command everytime client ID changes, only
2303 during first connecting. Affected file lib/silcclient/client.c.
2305 * Set the new nickname only after successful command reply for
2306 NICK command is returned by server. Affected file
2307 lib/silcclient/command.c.
2309 * Remove nicknames from nicklist during server_signoff notify.
2310 Should fix /NAMES bit more. The affected file is
2311 irssi/src/silc/core/silc-channels.c.
2313 * Added `fingerprint' field to the SilcIDListData in the
2314 silcd/idlist.h to hold the fingerprint of the client's
2317 Send the fingerprint of the client's public key in WHOIS
2320 Affected files silcd/command.c, and silcd/idlist.[ch].
2322 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
2323 create fingerprint from given data.
2325 * Show the fingerprint of the client's public key in WHOIS.
2326 Affected files irssi/src/module-formats.[ch] and
2327 irssi/src/silc/core/client_ops.c.
2329 * Format the multiple same nicknames also during JOIN and
2330 NICK_CHANGE notifys. Affected file is
2331 lib/silcclient/client_notify.c.
2333 * Do not print error on screen for invalid private message
2334 payload since it can come if someone is sending private
2335 messages with wrong key. Affected file
2336 lib/silccore/silcprivate.c.
2338 * Fixed multiple concurrent /PING crash. Affected file
2339 lib/silcclient/command.c.
2341 * Changed the wrong ID encoding. All IP addresses must be
2342 in MSB first order in encoded format. They were encoded
2343 wrong and was in LSB format. Affected files are
2344 silcd/serverid.c, lib/silcutil/silcutil.c.
2346 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
2348 * Call the `connect' client operation through the scheduler
2349 in case of error. Affected file lib/silcclient/client.c.
2351 * Call the `failure' client operation even if the error
2352 occurred locally during a protocol. Affected file is
2353 lib/silcclient/protocol.c.
2355 * Added support of sending LIST command to router from normal
2356 server. This way normal server can get list of all channels
2357 in the network too. Fixed the channel list sending in the
2358 server too. Affected files are silcd/command.c, and
2359 silcd/command_reply.[ch].
2361 * Added silc_server_update_channels_by_server and
2362 silc_server_remove_channels_by_server. They are used during
2363 disconnection of primary router and in backup router protocol.
2364 Affected file silcd/server_util.[ch], silcd/server.c and
2365 silcd/server_backup.c.
2367 * Fixed channel adding to global list in IDENTIFY command
2368 reply in server. Affected file silcd/command_reply.c.
2370 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2372 * If the incoming packet type is REKEY or REKEY_DONE process
2373 that packet always synchronously. Fixes yet another MAC
2374 failed error on slow (dialup) connections. Affected file
2375 lib/silcclient/client.c and silcd/server.c.
2377 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2379 * Call check_version SKE callback for initiator too. Affected
2380 file lib/silcske/silcske.c.
2382 * Implemented fix for security hole found in the SKE that was
2383 fixed in the specification few days back; the initiator's
2384 public key is now added to the HASH value computation.
2385 Added backwards support for the old way of doing it too, for
2386 old clients and old servers. Affected file is
2387 lib/silcske/silcske.c.
2389 * Enabled mutual authentication by default in SKE. If initiator
2390 is not providing mutual authentication the responder will
2391 force it. This will provide the proof of posession of the
2392 private key for responder. The affected files are
2393 lib/silcclient/protocol.c and silcd/protocol.c.
2395 * Do not cache anymore the server's public key during SKE.
2396 We do mutual authentication so the proof of posession of
2397 private key is done, and if the server is authenticated in
2398 conn auth protocol with public key we must have the public
2399 key already. Affected file silcd/protocol.c.
2401 * Added new global debug variable: silc_debug_hexdump. If
2402 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
2403 file lib/silcutil/silclog.[ch].
2405 * Fixed compilation warning due to char * -> const char *.
2406 Affected files lib/silcutil/silcnet.h, and
2407 lib/silccore/silcauth.[ch].
2409 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2411 * Fixed CMODE command when new channel key was created. If
2412 the creation failed the old key was removed. Next time giving
2413 same command would crash the server since the old key was
2414 freed already. Affected file silcd/command.c.
2416 * Fixed the silc_server_announce_get_channels to not crash
2417 on reconnect. Affected file silcd/server.c.
2419 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2421 * Added silc_log_set_debug_string function to set a regex
2422 string to match for debug output. Only the function names,
2423 or filenames matching the given debug string is actually
2424 printed. This way it is possible to filter out those debug
2425 strings that user is not interested in.
2427 Fixed a bug in silc_string_regexify.
2429 Affected files lib/silcutil/silclog.[ch], and
2430 lib/silcutil/unix/silcunixutil.c.
2432 * Changed the -d options in both server and Irssi SILC client
2433 to take the debug string as argument. Affected files
2434 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
2436 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2438 * Added silc_hash_babbleprint to create a Bubble Babble
2439 Encoded fingerprint. The encoding is developed by Antti
2440 Huima (draft-huima-babble-01.txt), and it creates human
2441 readable strings out of binary data. Affected file
2442 lib/silccrypt/silchash.[ch].
2444 * Print the babble print now in addition of fingerprint as well
2445 in Irssi SILC client. Affected files are
2446 irssi/src/fe-common/silc/module-formats.[ch],
2447 irssi/src/fe-common/silc/core/client_ops.c.
2449 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2451 * Fixed a security problem found in SKE. The initiator's
2452 public key too is now added to the HASH hash value creation
2453 which is signed by the responder to create the SIGN value.
2454 This will prevent anyone in the middle to lie to the responder
2455 about the initiator's public key. If this is done now, the
2456 man in the middle will get caught. Updated the protocol
2459 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2461 * Better installation directory handling. Configure module
2462 paths and other paths automatically to example_silc* files
2463 in doc/. A patch by toma.
2465 * Fixed compiler warning from MPI library, and from SILC RNG.
2468 * Added SILC_SERVER_PID_FILE to define the pid file for server.
2469 It can be configured with ./configure. A patch by toma.
2471 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2473 * Find correct make to use in prepare-clean. A patch by
2474 toma. Affected file prepare-clean.
2476 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
2478 * Added irssi variables use_auto_addr, auto_bind_ip,
2479 auto_bind_port and auto_public_ip.
2481 * Changed the interface for silc_client_send_key_agreement
2482 in lib/silcclient/silcapi.h
2486 irssi/src/silc/core/silc-core.c
2488 lib/silcclient/silcapi.h
2489 irssi/src/silc/core/silc-channels.c
2490 lib/silcclient/client_keyagr.c
2493 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2495 * Added silc_pkcs_public_key_compare to compare two
2496 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
2498 * Check that the client who set the founder mode on the
2499 channel is the same client that is giving the founder
2500 mode to itself. It is done by comparing the saved public
2501 key (it is saved even in the authentication is passphrase).
2502 Affected file silcd/command.c.
2504 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2506 * Do not process packet for disconnected socket connection.
2507 Affected file lib/silccore/silcpacket.c.
2509 * Process the DISCONNECT packet through scheduler in the
2510 client library. Affected file lib/silcclient/client.c.
2512 * Fixed the silc_client_packet_parse to not to increase
2513 the packet sequence number if the conn->sock and the
2514 current socket connection is not same. This can happen
2515 for example during key agreement when the conn includes
2516 multiple socket connections (listeners). Affected file
2517 lib/silcclient/client.c.
2519 * The sender of the file transfer request now provides also
2520 the pointer (listener) for the key exchange protocol. If
2521 the listener cannot be created then it sends empty key
2522 agreement and lets the receiver provide the listener.
2524 Added `local_ip' and `local_port' arguments to the
2525 silc_client_file_send. If they are provided they are used,
2526 if not then it will attempt to find local IP address, if
2527 not found or bind fails then the remote client will provide
2530 Affected files are lib/silcclient/client_ftp.c and
2531 lib/silcclient/silcapi.h.
2533 * Extended the FILE SEND command to support defining the
2534 local IP and port for key exchange listener. They are
2535 optional. Affected file irssi/src/silc/core/silc-servers.c.
2537 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2539 * Defined to WHOIS command reply the sending of fingerprint
2540 of the client's public key (if the proof of posession of the
2541 corresponding private key is verified by the server).
2542 Updated to the protocol specification.
2544 * Added support of receiving the client's public key's
2545 fingerprint in command reply in client library. Affected
2546 file is lib/silcclient/command_reply.c, and
2547 lib/silcclient/idlist.[ch].
2549 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2551 * Do not send over 128 chars long nickname to the server
2552 in NICK command. Affected file lib/silcclient/command.c.
2554 * Do not send over 256 chars long channel names to the server
2555 in JOIN command. Affected file lib/silcclient/command.c.
2557 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2559 * Assure that silc_server_close_connection cannot be called
2560 twice for same socket context. Affected file is
2563 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2565 * Send error message to application if opening file for
2566 writing during file transfer fails. Affected file is
2567 lib/silcclient/client_ftp.c.
2569 Remove all file transfer sessions for a client that we're
2570 removing from ID cache.
2572 Affected file is lib/silcclient/client_ftp.c.
2574 * Fixed silc_net_addr2bin to return correct address. Affected
2575 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2577 * Fixed file transfer session removing on signoff notify.
2578 Affected file irssi/src/silc/core/silc-servers.c.
2580 * Added the SilcClientFileError to be returned in the monitor
2581 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
2582 Affected file lib/silcclient/silcapi.h.
2584 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2586 * Fixed a crash in silc_client_ftp_free_sessions and
2587 silc_client_ftp_session_free_client. Affected file
2588 lib/silcclient/client_ftp.c.
2590 * Added `disabled' field in the SilcChannelEntry in the server
2591 to indicate if the server entry is disabled. Affected file
2592 silcd/idlist.h, silcd/command[_reply].c.
2594 * SILC server adds now /var/run/silcd.pid everytime it is
2595 started. Affected file silcd/silcd.c.
2597 * Added silc_server_packet_send_clients to send a packet to
2598 the provided table of client entries. Affected file
2599 silcd/packet_send.[ch].
2601 * Fixed a crash in client resolving in client_prvmsg.c in
2602 client library. Affected file lib/silcclient/client_prvmsg.c.
2604 * Do not actually remove the client directly from ID cache
2605 during SERVER_SIGNOFF, but invalidate it. This way we
2606 preserve the WHOWAS info for the client. Affected file
2607 silcd/server_util.c.
2609 * Fixed SERVER_SIGNOFF notify handling in the server. The
2610 server is now able to process incoming SERVER_SIGNOFF notify
2611 for a server that it doesn't even know about. It will remove
2612 the clients provided in the notify. Affected file
2613 silcd/packet_receive.c.
2615 * Check for partial packet in data queue after every packet that
2616 was found from the queue. Return and wait for more data if
2617 there is partial data in queue. Affected file is
2618 lib/silccore/silcpacket.c.
2620 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>

2635 irssi/src/fe-common/silc/module-formats.[ch].
2637 * Wrote a help file for FILE command.
2639 * Added silc_rng_global_get_byte_fast to get not-so-secure
2640 random data as fast as possible. Random data is read from
2641 /dev/urandom if available and from the SILC RNG if not
2642 available. It is used in padding generation. Affected file
2643 lib/silccrypt/silcrng.[ch].
2645 * All packets in client library are now processed synchronously.

2658 * Assure that silc_client_notify_by_server_resolve does not
2659 resolve the client information multiple times. If it cannot
2660 be found by the first it cannot be found at all. Affected
2661 file lib/silcclient/client_notify.c.
2663 * Fixed WHOWAS command reply calling. Affected file
2664 lib/silcclient/command_reply.c.
2666 * Removed all references to silc_idlist_get_client from the
2667 Irssi SILC client since that call is internal call used by
2668 the library. The Irssi SILC client will use now client
2669 retrieval functions found in silcapi.h.
2671 * Fixed a bug in resolving nickname info before sending
2672 private message. It used freed memory. Affected file
2673 irssi/src/silc/core/silc-servers.c.

2694 * Added silc_net_localip to return local host's IP address.
2695 Affected file lib/silcutil/silcnet.[ch].
2697 * If key exchange or rekey protocol is active for a connection
2698 parse all packets syncronously since there might be packets
2699 in packet queue that we are not able to process without first
2700 processing packets before them. Affected file silcd/server,
2701 lib/silcclient/client.c.
2703 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2704 whether library should continue processing the packet.
2705 Affected file lib/silccore/silcpacket.h.

2751 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
2752 is incomplete and is being resolved, it won't be resolved
2755 Make sure also that USERS command reply does not resolve
2756 twice information. Affected file is
2757 lib/silcclient/command_reply.c.
2759 Make sure that silc_client_get_clients_by_list does not
2760 resolve twice same information.
2762 * Check for valid client->id in the silc_server_free_client_data.
2763 Affected file silcd/server.c.
2765 * Fixed /GETKEY nick@server not to crash if the server entry
2766 is not found. Affected file lib/silcclient/command.c.
2768 * Fixed the silc_server_check_cmode_rights to check the
2769 requested modes correctly. Affected file silcd/command.c.

2774 Affected file silcd/command.c.
2776 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2778 * Call the silc_server_udpate_servers_by_server in the
2779 primary router that comes back online in the backup resuming
2780 protocol. Otherwise it routes packets wrong. Affected file
2781 silcd/server_util.[ch], silcd/server_backup.c.
2783 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2785 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2786 lib/silcutil/silcbuffmt.[ch].
2788 * Redefined the SILC packet header to include the padding
2789 length. Affected file lib/silccore/silcpacket.[ch].
2791 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2792 length for maximum padding up to 128 bytes). Affected
2793 file lib/silccore/silcpacket.h.
2795 * Removed all backwards support for old 0.5.x MAC thingies.
2796 The SILC packet header change makes it impossible to be
2797 backwards compatible.
2799 * Send the ENDING packet with timeout in the backup resuming
2800 protocol. This is to assure that all routers has connected
2801 to the primary router. Affected file silcd/server_backup.c.
2803 * Changed the RNG to take the first IV from random data. It
2804 used to take it from zero actually. Changed the RNG also
2805 to use /dev/urandom during session. /dev/random is used
2806 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2808 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2810 * Changed the SILC packet header to have the first two bytes
2811 (the packet length) encrypted. Affected files aroung the
2812 code tree, lib/silccore/silcpacket.[ch]. Removed the
2813 SilcPacketCheckDecrypt callback. It is not needed anymore
2814 since the silc_packet_receive_process will determine now
2815 whether the packet is normal or special.
2817 * Implemented the unidirectional MAC keys. Affected files
2818 lib/silcske/silcske.c, silcd/protocol.c and
2819 lib/silcclient/protocol.c.
2821 * Implemented the packet sequence number to the MAC computation.
2822 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
2823 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
2824 lib/silcclient/protocol.c.
2826 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2828 * Allow backup router to announce servers. All servers
2829 announced by backup router are added to the global list
2830 automatically. Update hte server's socket to our primary
2831 router also when backup router announces a server.
2832 Affected file silcd/packet_receive.c.
2834 * Do not update the client->router in the function
2835 silc_server_udpate_clients_by_server if the client is on
2836 global list. We might fail to find any specific server
2837 for locally connected clients and local cell clients. They
2838 should still use the `from' and not `to' as client->router.
2839 This fixes backup router resuming protocol. Affected file
2840 silcd/server_util.c.
2842 * Decrease channel statistics count only if the channel
2843 deletion worked. Affected files are silcd/server.c and
2844 silcd/server_util.c.
2846 * Added silc_server_update_servers_by_server to update origin
2847 of all server entries. Used during backup router protocol.
2848 Affected files silcd/server_util.[ch], silcd/server.c. and
2849 silcd/backup_router.c.
2851 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
2852 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
2853 silc_hmac_get_hash and silc_hmac_get_name. Affected file
2854 lib/silccrypt/silchmac.c.
2856 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2858 * Assure that router cannot reroute the same channel message
2859 to the sender. Affected file silcd/packet_receive.c.
2861 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2863 * Made better checks that the channel message is not sent
2864 to the router it came from. Affected file is
2865 silcd/packet_send.c. Fixed memory leak too.
2867 * Announce informations for incoming router connection, but
2868 only after checking if it is replaced by backup router.
2869 Affected file silcd/packet_receive.c.
2871 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2873 * Fixed the backup resuming protocol to work in multiple
2874 router environment. Affected file silcd/server_backup.c.
2876 * Route packet only to one router in the function
2877 silc_server_packet_send_to_channel. Affected file is
2878 silcd/packet_send.c.
2880 * Fixed silc_server_send_notify_dest to set the broadcast
2881 flag. Fixed the silc_server_send_notify_topic to actually
2882 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2883 Affected file silcd/packet_send.c.
2885 * Changed the SFTP Filesystem interface. Changed the
2886 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2887 the filesystem operation function. The SilcSFTPFilesystem
2888 is now a context that is allocated by all filesystem allocation
2889 functions and it already includes the operations structure
2890 and filesystem specific context. It is given as argument
2891 now to the silc_sftp_server_start. This made the interface
2892 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2893 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2895 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2897 * Changed the backup router adding and getting interfaces
2898 in the server. The router that will be replaced by the
2899 specified backup router is now sent as argument. Affected
2900 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2903 * Added silc_net_addr2bin_ne to return the binary form of
2904 the IP address in network byte order. Affected files
2905 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
2907 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2909 * Check for existing server ID in silc_server_new_server
2910 and in silc_server_connect_to_router_final and remove the
2911 old entry if it exists. Affected file silcd/packet_receive.c,
2914 * Send the channel message always to only one router, either
2915 in upstream or downstream. Affected file is
2916 silcd/packet_send.c.
2918 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2920 * Wrote the definition of the backup resuming protocol to the
2921 protocol specification.
2923 * Removed one redundant channel key generation from normal
2924 server during joining procedure. Removed one redundant
2925 channel key sending from server to router during joining
2926 procedure. Affected file silcd/command.c.
2928 * Made minor bugfixes to the backup router resuming protocol.
2929 Affected file silcd/server_backup.c, server.c.

2934 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
2937 * Implemented the backup resuming protocol that is used to
2938 resume the primary router position in the cell after the
2939 primary router comes back online. Affected files
2940 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
2941 and silcd/server_util.[ch].
2943 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2945 * Sleep two (2) seconds after sending QUIT command to server.
2946 Affected file lib/silcclient/command.c.
2948 * Assure that if outgoing data buffer is pending do not force
2949 send any data. Affected file silcd/packet_send.c.
2951 * Assure that if outgoing data buffer is pending do not force
2952 send any data. Affected file lib/silcclient/client.c.
2954 * Implemented the backup router support when the primary router
2955 goes down. The servers and routers can now use the backup
2956 router as new primary router without loosing connectivity.
2958 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2960 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
2961 in the server to indicate disabled entry. All data read
2962 from the connection will be ignored and no data is sent
2963 for entry that is disabled. Affected files are
2964 silcd/idlist.h, silcd/server.c.
2966 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2968 * Created SFTP client and server test programs in the
2969 lib/silcsftp/tests directory.
2971 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2973 * Implemented memory filesystem (virtual filesystem) for
2974 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
2977 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2979 * Implemented the SFTP (SSH File Transfer Protocol) to the
2980 lib/silcsftp. It includes SFTP client and SFTP server
2983 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2985 * Moved lib/silccore/silcprotocol.[ch] to the
2986 lib/silcutil library.
2988 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
2989 take variable argument list pointer as argument. Affected
2990 file lib/silcutil/silcbuffmt.[ch].
2992 * Added silc_buffer_set function that is used to set data
2993 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
2994 Affected file lib/silcutil/silcbuffer.h.
2996 * Changed various routines in the core library to use the new
2997 silc_buffer_set instead of allocating new buffer only for
3000 * Added 64-bit value formatting and unformatting support to the
3001 silc_buffer_[un]format routines. Affected file is
3002 lib/silcutil/silcbuffmt.[ch].
3004 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
3005 to includes/bitmove.h.
3007 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3009 * Fixed channel user mode saving in client library. Affected
3010 file lib/silcclient/command[_reply].c.
3012 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3014 * Defined the file transfer to the SILC Protocol. Added
3015 new packet type SILC_PACKET_FTP and defined File Transfer
3016 Payload. The mandatory file transfer protocol is SFTP
3017 (SSH File Transfer Protocol). Affected file in addition
3018 of the internet draft is lib/silccore/silcpacket.h.
3020 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
3021 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
3022 is used as part of backup router protocol when the primary
3023 router of the cell is back online and wishes to resume
3024 the position as primary router.
3026 * Redefined the MAC generation keys in the protocol. The
3027 same key is not used anymore in both direction. Both
3028 direction will now use different keys for sending and
3029 receiving. This fixes a potential security flaw. This
3030 change causes incompatibilities in the protocol.
3032 * Redefined also the MAC computation from the packet.
3033 An packet sequence number is now added to the MAC
3034 computation. This prevents possible replay attacks against
3035 the protocol. This change too causes incompatibilities
3038 Added `sequence' field to the SilcPacketContext to hold
3039 the current sequence number for the packet.
3041 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3043 * Added `created' field to the SilcIDListData in the file
3044 silcd/idlist.h to indicate the time when the entry was
3047 * Added `created' field to the SilcChannelEntry too. Affected
3048 file silcd/idlist.h.
3050 * Added `creation_time' aguments to all the announcement functions
3051 in the server. If it is provided then only the entries that
3052 was created after the provided time frame are actually
3053 announced. Affected file silcd/server.[ch].
3055 * The protocol says that the Channel ID's IP address must be
3056 based on the router's IP address. Added check for this in
3057 the silc_server_new_channel when processing incoming New Channel
3058 Payload. Affected file silcd/packet_receive.c.
3060 * Print out the correct version with --version in SILC client.
3061 Affected file irssi/src/silc/core/silc-core.c.
3063 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3065 * Fixed WHOWAS command to check for completnes of the client
3066 entry always, not just when the command is coming from client.
3067 Affected file silcd/command.c.
3069 * Added new function silc_server_packet_queue_purge to purge the
3070 outgoing data queue to the network. After the function returns
3071 it is guaranteed that the outgoing packet queue is empty.
3072 Affected file silcd/packet_send.[ch].
3074 * Purge the outgoing packet queue in the rekey protocol's final
3075 callback to assure that all rekey packets go to the network
3076 before quitting the protocol. Affected file silcd/server.c.
3078 * Added silc_client_packet_queue_parse as similar function as
3079 in server to the client library. The affected file is
3080 lib/silcclient/client.c.
3082 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3084 * Splitted silcd/server.c and created silcd/server_util.[ch]
3085 for utility functions.
3087 * Added new socket flag SILC_SF_DISABLED to indicate that the
3088 connection is open but nothing can be sent to or received from
3089 the connection. Affected file lib/silcutil/silsockconn.[ch].
3090 The checking for disabled socket is checked in the low level
3091 silc_socket_write and silc_socket_read functions.
3093 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3095 * Allow only nicknames and channel names that fits into the
3096 7-bit unsigned char ASCII set. Affected file silcd/command.c.
3098 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3100 * When processing JOIN command reply in server check that if
3101 the channel exists in our global list we'll move it the local
3102 list. Affected file silcd/command_reply.c.
3104 * Fixed the check whether client is joined on the channel already
3105 in JOIN command. Affected file lib/silcclient/command.c.
3107 * Fixed the JOIN command reply to check whether the channel
3108 already exists. Affected file lib/silcclient/command_reply.c.
3110 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3112 * Added silc_ske_status_string to map the SKE error numbers
3113 to readable strings. The affected files are
3114 lib/silcske/silcske[_status].[ch].
3116 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3118 * Do not show the private channels on the WHOIS channel list
3119 as it is not allowed by the protocol. The affected file is
3122 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3124 * Assure that the packet length digged from the actual packet
3125 is something sensible in the silc_packet_decrypt_rest_special
3126 in lib/silccrypt/silcpacket.c.
3128 * Free and NULL the allocated pointer in silc_hmac_alloc if
3129 the HMAC allocation fails. The affected file is
3130 lib/silccrypt/silchmac.c.
3132 * Print the selected security properties to the log files in
3133 the server. Affected file silcd/protocol.c.
3135 * Add SKE's reference counter even if calling the completion
3136 callback manually. Otherwise it goes negative, although it
3137 does not cause any problems. The affected file is
3138 lib/silcske/silcske.c.
3140 * Remove the client entry with short timeout after giving the
3141 KILL command. Affected file lib/silcclient/command.c.
3143 * Fixed to send error reply in WHOIS and IDENTIFY commands in
3144 case all found clients are already disconnected (WHOWAS would
3145 found them) in the server. Affected file silcd/command.c.
3147 * Update the last_receive (time of last data received) to be
3148 updated only when received private or channel message so that
3149 the idle time showed in WHOIS makes more sense.
3151 * Added boolean field `valid' in to the SilcClientEntry in the
3152 client library to indicate whether the entry is valid or not.
3153 This fixes the nickname change bug on channel when changing
3154 the nickname to be same than the old (like nick to Nick) the
3155 nickname formatter doesn't set the new nick anymore to Nick@host.
3156 Affected file lib/silcclient/idlist.[ch].
3158 * Now actually fixed the nickname changing on disconnection.
3159 Added new function silc_change_nick to the Irssi SILC Client.
3160 Affected file irssi/src/silc/core/client_ops.c,
3161 irssi/src/silc/core/silc-nicklist.[ch].
3163 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3165 * Check that the public key exists in the GETKEY command before
3166 trying to encode it. Affected file silcd/command.c.
3168 * Print some notifications on received public keys with GETKEY
3169 command in the Irssi SILC Client. Affected files are
3170 irssi/src/fe-common/silc/module-formats.[ch],
3171 irssi/src/silc/core/client_ops.c.
3173 * Use IDENTIFY command to resolve the server information in the
3174 GETKEY command instead of INFO command. Affected file
3175 lib/silcclient/command.c.
3177 * All command reply functions in the client library now calls
3178 the pending command reply callbacks even if an error has
3179 occurred. The server has done this a long time and now it was
3180 time to move the client library to this as well. Now all
3181 errors can be delivered back to the pending command reply
3182 callbacks if necessary. Affected files are
3183 lib/silcclient/command[_reply].[ch].
3185 * Change the nickname on disconnection back to the username
3186 because in reconnect the server will enforce it to it anyway.
3187 Affected file irssi/src/silc/core/silc-servers.c.
3189 * Fixed a config file parsing bug in the Irssi SILC client.
3190 Affected file irssi/src/silc/core/clientconfig.c.
3192 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3194 * When printing the channel mode on JOIN, verify that the
3195 channel key and channel's HMAC are valid. Affected file
3196 irssi/src/silc/core/client_ops.c.
3198 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3200 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
3201 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
3202 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
3204 * Removed channel key rekey task deleting from the function
3205 silc_server_save_channel_key. Affected file silcd/server.c.
3206 Added explicit timeout task context instead that is used to
3207 delete the task if we are registering a new task before the
3208 new task has elapsed.
3210 * When channel key rekey occurs the client library now saves
3211 the old channel key for a short period of time (10 seconds) and
3212 is able to use it in case some is still sending channel
3213 messages encrypted with the old key after the rekey. Affected
3214 file lib/silcclient/[idlist.h|client_channel.c].
3216 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3218 * Added check to the silc_server_new_id_real to not accept
3219 new ID if it is the sender's own ID. Affected file is
3220 silcd/packet_receive.c.
3222 * Assure that we do not announce ourself or the one we've
3223 sending our announcements when we're router and are announcing
3224 servers to our primary router. Affected file silcd/server.c.
3226 * Fixed silc_server_command_identify_check_client to assemble
3227 correct WHOIS packet. It send corrupted WHOIS packet and
3228 caused problem with router to router connections. Affected
3229 file silcd/command.c.
3231 Fixed also silc_server_command_whois_check the same way
3232 as for the IDENTIFY command.
3234 * Added new SilcIDListStatus to the server in the SilcIDListData
3235 structure. The status now includes the current status of
3236 the entry (like registered, resolved etc.). Affected file
3237 silcd/idlist.[ch]. Defined a bunch of different status types
3238 as well. This replaced the old boolean registered field as well.
3240 Added resolve_cmd_ident field to the SilcClientEntry structure
3241 too so that if the entry is for example being resolved so
3242 another command may attach to the same pending command reply
3243 without requiring to resolve the same entry again. This concept
3244 should optimize the WHOIS and the IDENTIFY resolving under
3245 heavy load by taking away unnecessary resolving for entries
3246 that are being resolved already.
3248 Added support for adding multiple pending commands for one
3249 command idenfier. Affected file silcd/command[_reply].[ch].
3251 * Fixed WHOIS and IDENTIFY save to remove the cache entry
3252 before deleting the data. Otherwise the hash table will have
3253 freed data in comparison functions. Affected file is
3254 silcd/command_reply.c.
3256 * Fixed silc_idlist_replace_client_id to add the new entry to
3257 the cache with NULL nickname. Otherwise there will be invalid
3258 memory as the nickname after the nickname is freed. Affected
3259 file silcd/packet_receive.c.
3261 * Fixed the silc_idlist_get_clients_by_hash. The entries was
3262 saved into wrong slots because the previous number of entries
3263 was not taken into account. Affected file silcd/idlist.c.
3264 Fixed same thing in silc_idlist_get_clients_by_nickname too.
3266 * If we are router and we receive JOIN notify to a channel that
3267 does not have any users then notified client is marked as the
3268 channel founder, as it is it. The affected file is
3269 silcd/packet_receive.c
3271 * Added to the extended hash table API's table_del_*ext functions
3272 the destructor as argument too, so that the caller can decide
3273 which destructor to use or whether to use destructor at all.
3274 Affected file lib/silcutil/silchashtable.[ch].
3276 * Fixed ID Cache purging. It actually deleted the entries from
3277 the hash table after the data was freed. The hash table ended
3278 up comparing freed memory. The affected file is
3279 lib/silccore/silcidcache.c.
3281 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3283 * Fixed Irssi SILC client's KILL command's HELP syntax.
3285 * The USERS command now resolves the detailed user information
3286 if the userinfo field is missing. Affected file is
3287 lib/silcclient/command_reply.c.
3289 * Do not print error in silc_file_read if the read file does
3290 not exist. Just silently return NULL. Affected file is
3291 lib/silcutil/silcutil.c.
3293 * Fixed the silc_log_output to not wine about NULL filename
3294 and to not create some bogus " " filename. Affected file is
3295 lib/silcutil/silclog.c.
3297 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3299 * Fixed various printing bugs on the user interface in the
3300 Irssi SILC Client. Minor changes that were forgotten from
3303 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3305 * Fixed the configure.in.pre and the compilation and distribution
3306 environment to support the new autoconf 2.52. That version is
3307 now required to compile the CVS trunk.
3309 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3311 * Renamed function silc_parse_nickname to silc_parse_userfqdn
3312 to generally parse user@fqdn format strings. Affected file
3313 lib/silcutil/silcutil.c.
3315 * Added nickname_format and nickname_force_format fields to the
3316 SilcClientParams structure. The first one defines the format
3317 for the nicknames that the library will enforce if the receives
3318 multiple same nicknames. The second one is boolean value and
3319 can be used to force the library to always enforce the format
3320 to the nicknames regardles whether there are multiple nicknames
3321 or not. This configurable formatting was employed to flexibly
3322 support accessing multiple nicknames from the user interface.
3323 The userinterface can now set the nicknames to what ever format
3324 they prefer. Affected file lib/silcclient/silcapi.h.
3326 Added function silc_client_nickname_format to the file
3327 lib/silcclient/idlist.c. It performs the nickname formatting.
3329 Added new field `hostname´ to the SilcClientEntry context.
3330 It holds the hostname of the client. Affected file is
3331 lib/silcclient/idlist.h.
3333 * Irssi SILC Client sets the nicknames in nick@hostn format.
3334 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
3335 irssi/src/silc/core/silc-core.c.
3337 The WHOIS printing now also shows both the real nickname and
3338 the formatted nickname so that user knows how to access the
3339 user if there are multiple same nicknames cached. Affected
3340 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
3341 printing formatting too to take the hostname now as a separate
3342 argument. The Affected file is
3343 irssi/src/fe-common/silc/modules-formats.[ch].
3345 * Changed the silc_client_get_clients_local to accept the formatted
3346 nickname as argument. It accepts the real nickname too but the
3347 formatted nickname can be used to find the true entry from
3348 multiple entries. Affected file lib/silcclient/silcapi.h and
3349 lib/silcclient/idlist.c.
3351 * Added nickname_format_parse field to the SilcClientParams.
3352 It is a callback function provided by the application to parse
3353 the nickname out of the formatted nickname string. The library
3354 calls it to get the nickname from the formatted string. Since
3355 the application generally knows better the format of the nickname
3356 string it parses it instead of the library, even though library
3357 encodes the formatted string. If the callback function is not
3358 provided then the library will use the string as is. The
3359 affected file is lib/silcclient/silcapi.h.
3361 * All the nickname strings passed to the client library in
3362 commands are now expected to be formatted nickname strings.
3363 If the command does not support the formatted nickname string
3364 it will assume that the sent string is the actual nickname.
3365 Affected file lib/silcclient/command.c.
3367 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3369 * Added public key authentication support to OPER and SILCOPER
3370 commands in the client library. Affected file is
3371 lib/silcclient/command.c.
3373 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3375 * Changed the get_auth_methdod client operation to be asynchronous.
3376 It can be async if the application resolves the authentication
3377 method from the server during the negotiation. Added new
3378 SilcGetAuthMeth completion callback that the application will
3379 call after resolving the authentication method.
3381 Added function silc_client_request_authentication_method that
3382 the application can use to resolve the authentication method
3383 from the server. Added also SilcConnectionAuthRequest callback
3384 that the library will call after the server has replied. The
3385 application can call this function if it does not know the
3386 current authentication method.
3388 Affected files are lib/silcclient/client.c and
3389 lib/silcclient/silcapi.h.
3391 * The Irssi SILC client now automatically resolves the authentication
3392 method incase any configuration information is not present (and
3393 currently there never is). The affected file is
3394 irssi/src/silc/core/client_ops.c.
3396 * Fixed public key authentication from the client library.
3397 Affected file lib/silcclient/protocol.c. Changed also the
3398 protocol specification about the public key authentication in
3399 the connection authentication protocol. The actual data to be
3400 signed is now computed with a hash function before signing.
3402 * Fixed the public key authentication from the server as well.
3403 Affected file silcd/protocol.c.
3405 * Removed the mlock()'s from the memory allocation routines.
3406 Affected file lib/silcutil/silcmemory.c. The ./configure does
3407 not check anymore for the mlock(). Affected file is
3410 * Fixed USERS command in server to allow the execution of the
3411 command for private and secret channels if the client sending
3412 the command is on the channel. Affected file silcd/command.c.
3414 * Fixed silc_client_get_clients_local to return the clients
3415 count correctly. It could return wrong value. Affected file
3416 lib/silcclient/idlist.c.
3418 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3420 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
3421 types. The assembler optimizations seemed not to like 64-bit
3422 data types. The assmebler optimizations thus are now enabled
3423 also for BSD systems as opposed to only enable them for Linux.
3425 * Do not check for threads at all on BSD systems. Affected
3426 file configure.in.pre.
3428 * Removed -n and -h options from the Irssi SILC Client since
3429 they are not used in silc.
3431 * Fixed the prime generation to assure that the first digit
3432 of the generated random number is not zero since our conversion
3433 routines does not like number strings that starts with zero
3434 digit. If zero digit is seen the random number is regenerated.
3435 This caused some corrupted RSA keys when the zero first digit
3436 was met. Affected file lib/silcmath/silcprimegen.c.
3438 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3440 * Fixed WIN32 configuration in the ./configure script.
3441 Fixed to include xti.h on environments that has it.
3442 Patches by Carsten Ilchmann and andrew.
3444 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3446 * Changed the silc_id_create_client_id to be collision
3447 resistant. It is now assured that there cannot be created
3448 two same client ID's. I suspect that some weird bugs in
3449 the server were actually caused by duplicate Client IDs.
3450 Affected file silcd/serverid.[ch]. A router receiving
3451 new ID now also assures and informs the sending server
3452 if the ID caused collision.
3454 * Changed the silc_id_create_channel_id to also assure that
3455 there are no collisions.
3457 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3459 * Statement about ignoring the Mutual Authentication flag when
3460 performing rekey with PFS was a bit misleading. It is ignored
3461 if it was set in the initial negotiation, it cannot be even
3462 set in the rekey. Fixed in the ke-auth draft. Started the
3463 new versions of the protocol drafts in the doc/.
3465 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3467 * Fixed a bug in silc_client_command_identify_save when saving
3468 new channel information. The channel name was no duplicated
3469 and caused crash on exit. Affected file is
3470 lib/silcclient/command_reply.c.
3472 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3474 * Fixed the getkey command handling in the server. Send just
3475 empty OK reply to the sender if the key could not be fetched
3476 (but everything else was ok, like the key just was not available).
3477 Changed the public key parameter to optional in the protocol
3478 specs so that empty OK reply can be sent. Affected file
3481 Added a message to Irssi SILC client to tell to user if the
3482 server did not return a public key.
3484 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3486 * Fixed a channel key regeneration bug. It registered new
3487 timeout tasks exponentially until all system resources were
3488 used. Affected file silcd/server.c.
3490 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3492 * Added the SILC Document generator to the scripts/silcdoc.
3493 It can be used to generate the Toolkit Reference Manual out
3494 of the source tree. Internally it will also use the RoboDoc
3495 generator now imported in util/robodoc.
3497 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3499 * Added couple of return's in rekey protocol if error orccurred
3500 during the protocol. The execution must be terminated.
3501 Affected file silcd/protocol.c. Also, terminate the protocol
3502 always with timeout.
3504 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3506 * The client's Client ID was created initally from the wrong
3507 nickname (it could have been in format nick@host) in the
3508 silc_server_new_client. Affected file silcd/packet_receive.c
3510 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3512 * Added some SILC_LOG_ERROR's to various error conditions
3513 if client could not be added to ID cache. Affected files
3514 silcd/packet_receive.c and silcd/server.c.
3516 * When client's sock->user_data is freed, NULL also the
3517 client->router and client->connection pointers. Added check
3518 for these pointers being NULL to various places around the
3519 code. Affected file silcd/server.c.
3521 * Added client->data.registered == TRUE checks to various
3522 places around the code to assure that unregistered client's
3523 are not handled when it is not allowed. Affected file
3526 * Added `bool registered' fields to all
3527 silc_idlist_[server|client]_get_* routines to indicate whether
3528 the fetched client needs to be registered or not. Affected
3529 file silcd/idlist.[ch].
3531 * Add your own entry as registered to the ID cache in the
3532 server. Affected file server.c.
3534 * Fixed a bug in silc_server_new_server. The SilcServer was
3535 set as the new server's context instead of SilcServerEntry.
3536 This naturally caused some weird bugs.
3538 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3540 * Do not delete the channel rekey task when adding it
3541 for in silc_server_create_channel_key.
3543 * Changed the silc_server_create_channel_key to return
3544 TRUE or FALSE to indicate the success of the channel key
3547 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3549 * Fixed MSVC++ project files and added missing files to
3550 Makefiles under win32/.
3552 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3554 * Do not add TCP_NODELAY flag if the operating system
3555 does not have it defined. Affected files are
3556 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3558 * Fixed buffer overflow from Irssi SILC Client. Affected
3559 file irssi/src/fe-common/core/themes.c.
3561 * Fixed double free in client library in the file
3562 lib/silcclient/client.c when disconnecting from server.
3564 * Applied double free patch from cras to Irssi SILC client.
3565 Affected files irssi/src/core/[modules/expandos].c
3567 * Fixed the disconnection handling to Irssi SILC Client.
3568 The application must call silc_client_close_connection
3569 in ops->connect client operation in case of failure of
3570 the connection. Affected file is
3571 irssi/src/silc/core/client_ops.c.
3573 * Do not set sock->protocol to NULL in the function
3574 silc_client_close_connection after executing the protocol's
3575 final callback since the sock might not be valid anymore.
3576 Affected file lib/silcclient/client.c.
3578 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3580 * Do not enable SILC_THREADS if the linking with libpthread
3581 did not happen. Affected file configure.in.pre.
3583 * Added notion to protocol specification that server must
3584 verify the sent authentication payload with CMODE when
3585 setting the channel founder key. Implemented it to the
3586 server. Affected file silcd/command.c.
3588 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3590 * Added _EXTRA_DIST SILC distribution variable to the
3591 distributions file. It is used to conditionally add extra
3592 files or directories to the specific distribution. Affected
3593 files ./prepare, Makefile.am.pre and distributions.
3595 Removed the `_' from the start of the distribution names.
3598 * Added README.WIN32 for instructions to compile the Toolkit
3601 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3603 * Fixed a double free in disconnection in the server. Affected
3604 file is silcd/server.c.
3606 * Fixed the lib/silcske/groups.c to work now also with GMP
3607 MP library. The string conversion did not work when using
3608 specific base and the base is indicated in the string as well.
3610 * Created win32/ directory which now includes MSVC++ specific
3611 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3612 It will appear only in the toolkit distribution
3614 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3616 * Changed the key material distribution function in case when
3617 the hash output is too short. The data is now concatenated
3618 a bit differently than it used to. Made the change to the
3619 SKE protocol specification.
3621 * Added better GMP detection to configure.in.pre. A patch
3624 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3626 * Fixed a minor bug in SKE that might cause some problem on
3627 some platforms. Affected file lib/silcske/silcske.c.
3629 * Added the cookie checking for initiator in the SKE. It checks
3630 that the responder returns the sent cookie unmodified. The
3631 affected file is lib/silcske/silcske.c. Added new SKE
3632 error type INVALID_COOKIE that can be sent during the
3633 negotiation. Fixed some memory leaks as well.
3635 * Added the "invalid cookie" error message to Irssi SILC client's
3638 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3640 * Added `task_max' field to the SilcClientParams to indicate
3641 the maximum tasks the scheduler can handle. If set to zero,
3642 default values are used. Affected file lib/silcclient/silcapi.h.
3644 * Fixed memory leaks in silc_client_close_connection. Affected
3645 file lib/silcclient/client.c.
3647 * Added silc_client_del_client_entry to client library to free
3648 all memory of given client entry. Affected file is
3649 lib/silcclient/idlist.[ch].
3651 * Added new functions silc_client_del_channel and
3652 silc_client_del_server to delete channel and server entries.
3653 Affected file lib/silcclient/[silcapi.h/idlist.c].
3655 * Removed silc_client_del_client_by_id from silcapi.h.
3657 * Fixed the INFO command to return the server's own info
3658 correctly when querying by Server ID. Affected file is
3661 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3663 * Removed the non-blocking settings in WIN32 code in the
3664 silc_sock_[read/write] and added SleepEx instead. Affected
3665 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3666 of input data is now checked with FIONREAD and ioctlsocket.
3668 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3670 * Call silc_schedule_task_del_by_context in the
3671 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3672 Affected file lib/silccore/silcprotocol.c.
3674 * Call silc_protocol_cancel for active protocols in the
3675 silc_server_close_connection if the funtion
3676 silc_server_free_sock_user_data has not been called.
3677 Affected file silcd/server.c.
3679 * Generic tasks cannot be deleted using the del_by_fd
3680 task deleting function since generic tasks does not match
3681 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3683 * Added a notion to SILCOPER help file that the SILCOPER works
3684 only on router server, not on normal server.
3686 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3688 * Added for WIN32 support for the new scheduler as well.
3689 Affected file lib/silcutil/win32/silcwin32schedule.c.
3691 * Fixed the SHA1 implementation to work on various platforms.
3693 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3695 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3696 API. It is part of the scheduler now. Everything else is
3697 as previously but some functions has changed their names.
3698 Checkout the lib/silcutil/silcschedule.h for the interface.
3699 Updated all applications to use the new interface. Affected
3700 files are lib/silcutil/silcschedule.[ch].
3702 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3704 * Found a bug in the SKE implementation. The HASH value,
3705 specified by the protocol, was not computed correctly. The
3706 public key of the responder was not added to the computation
3707 even though it is mandatory. Affected file lib/silcske/silcske.c.
3708 This unfortunately causes incompatibilities with older
3709 clients and servers.
3711 * Added WIN32 specific network init and uninit functions:
3712 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3713 the Winsock2. Affected file lib/silcutil/silcnet.h and
3714 lib/silcutil/win32/silcwin32net.c.
3716 * Set the socket always to nonblocking mode on WIN32 after
3717 reading data or writing data. Affected file is
3718 lib/silcutil/win32/silcwin32sockconn.c.
3720 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3722 * Fixed various compilation problems under WIN32. Affected
3723 files lib/silcutil/win32/silcwin32thread.c and
3724 lib/silcutil/win32/silcwin32schedule.c.
3726 * Removed all _internal.h #includes from public header
3727 files. Internal headers must never be included from
3730 Removed also the lib/silcske/payload_internal.h file.
3732 * All include files that may be needed (public and some others
3733 included by the public headers) by application developers are
3734 now copied to the ./includes directory. It does not copy any
3735 internal headers. Affected file Makefile.defines.pre and all
3736 Makefile.am's under lib/ and subdirs.
3738 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3740 * Do not change the ~/.silc directory's permissions automatically.
3741 Affected file irssi/src/silc/core/clientutil.c.
3743 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3745 * Do not cancel the protocol in silc_server_close_connection
3746 it might cause recursion. Now cancelled in the function
3747 silc_server_free_sock_user_data. Affected file silcd/server.c.
3749 * Fixed the silc_server_remove_clients_by_server to regenerate
3750 the channel keys correctly finally. Added also new function
3751 silc_server_remove_clients_channels to actually do it.
3752 Affected file silcd/server.c.
3754 * Fixed the silc_server_new_channel to not crash by giving
3755 wrong router to the new channel. Affected file is
3756 silcd/packet_receive.c.
3758 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3760 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3761 which is given as argument to the silc_client_alloc now.
3762 It can be used to configure the client and set various parameters
3763 that affect the function of the client.
3765 * The USERS command in server did not check whether the channel
3766 is private or secret. Affected file silcd/command.c.
3768 * Added new argument to the USERS command in protocol specification.
3769 The USERS command now can take the channel name as argument
3770 as well. Added support for this in client and server and
3771 updated the protocol specs.
3773 * Completed the GETKEY command in client. It can be now used
3774 to fetch also servers public key not only some clients.
3775 Affected files lib/silcclient/command[_reply].c.
3777 * Added silc_client_get_server to return server entry by the
3778 server name. Affected files lib/silcclient/silcapi.h and
3781 * Redefined the IDENTIFY command in protocol specification to be
3782 more generic. It now can be used to query information about
3783 any entity in the SILC Network, including clients, servers and
3784 channels. The query may be based either the entity's name
3785 or the ID. Added support for this in both client and server.
3787 Affected files silcd/command.c and lib/silcclient/command.c
3788 and command_reply.c.
3790 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3791 the _from_client and _from_server functions. Affected file
3794 * Added silc_client_get_channel_by_id_resolve to the file
3795 lib/silcclient/silcapi.h to resolve channel information by
3796 its ID. Added also silc_client_get_channel_by_id that
3797 does not resolve it from the server.
3799 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3801 * Added SilcServerEntry context into the client library
3802 to represent one server. The INFO command now allocates
3803 these to save the resolved server info. For now on the
3804 client library will also keep information about servers,
3805 connected and resolved with INFO.
3807 The INFO command now allocates the SilcServerEntry context
3808 and saves the server info there. The COMMAND_REPLY in
3809 the INFO now returns the parameters to application in
3810 same order as defined in the protocol specification.
3812 The entries are cached in the client->server_cache.
3814 * The INFO command is now issued after received the Client ID
3815 from the server. Affected file lib/silcclient/client.c.
3817 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3818 to the application as the mode changer might be server.
3819 It is guaranteed that NULL is not returned anymore to the
3820 application. Affected file lib/silcclient/client_notify.c.
3822 The ID Type is now also passed to the application so that
3823 it can check whether the returned entry is SilcClientEntry
3826 Added new function silc_client_get_server_by_id to return
3827 the server entry by ID. Affected files are the
3828 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3830 * Do not create the channel in the Irssi SILC Client when issuing
3831 the JOIN command but when received the sucessful JOIN command
3832 reply. Otherwise the channel might get created even though we
3833 could not join it. The Affected file is
3834 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3836 * Fixed a channel joining bug in router. The router must also
3837 check the channel modes, invite and ban lists etc. when serving
3838 the JOIN command sent by normal server. Affected file is
3839 silcd/command.c. The router now resolves the client's
3840 information from the server who sent the JOIN command if it
3841 does not know it, and processes the JOIN command only after
3844 * Changed the SilcCommandCb to take new argument; void *context2.
3845 Affected file lib/silccore/silccommand.h
3847 The second argument in the command callbacks in the server now
3848 includes the SilcServerCommandReplyContext if the command was
3849 called as pending command callback from the command reply.
3850 Otherwise it is NULL. When called as pending the status of the
3851 command reply will be checked and if it was erronous the
3852 error will be sent to the original sender of the command.
3853 This way the client always receives the error messages even
3854 though the server was actually the one who received the error
3855 when it resent the command to router, for example. Affected
3856 files silcd/command[_reply].[ch].
3858 * Fixed sending WHOWAS command's error message to client if
3859 the requested client could not be found. It was missing.
3862 * Changed the CMODE and CUMODE commands reply arguments in the
3863 protocol specification. The Channel ID is now sent in both
3864 of the commands to identify the channel. Implemented this
3865 new feature to the client and server. Affected files
3866 lib/silcclient/command_reply.c and silcd/command.c.
3868 * Made better checks for invite and ban lists in the JOIN
3869 command in server. Affected file silcd/command.c.
3871 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3873 * The server now performs the incoming host IP/DNS lookup
3874 using the silc_socket_host_lookup and thus does not block
3875 the server anymore. Affected file silcd/server.c.
3877 * Completed the multi-thread support for SILC Scheduler in
3878 the lib/silcutil/silcschedule.c.
3880 * Fixed the configure.in.pre to detect the pthread correctly
3883 * Fixed a deadlock in silc_task_queue_wakeup in the file
3884 lib/silcutil/silctask.c.
3886 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3888 * Added new function silc_schedule_wakeup that is used in
3889 multi-threaded environment to wakeup the main thread's
3890 schduler. It needs to be used when a thread adds a new task
3891 or removes a task from task queues. After waking up, the
3892 scheduler will detect the task queue changes. If threads
3893 support is not compiled in this function has no effect.
3894 Implemented the wakeup mechanism to both Unix and WIN32
3895 systems. Affected files are lib/silcutil/silcschedule.[ch],
3896 lib/silcutil/unix/silcunixschedule.c and the
3897 lib/silcutil/win32/silcwin32schedule.c.
3899 * Added new function silc_task_queue_wakeup to wakeup the
3900 scheduler by the specified task queue. Affected file
3901 lib/silcutil/silctask.[ch].
3903 * The silc_socket_host_lookup_start now wakes up the scheduler
3904 after adding the timeout task. Affected file is
3905 lib/silcutil/silcsockconn.c.
3907 * The silc_socket_host_lookup is synchronous now if the threads
3908 support is not compiled in. However, the callback is still
3909 called asyncronously through the scheduler, anyway. Affected
3910 file lib/silcutil/silcsockconn.c.
3912 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3914 * Added new function silc_socket_host_lookup to perform
3915 asynchronous IP and FQDN lookups for the socket connection.
3916 Affected files lib/silcutil/silcsockconn.[ch].
3918 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3920 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3921 that may or may not compile the mutex support in.
3923 Changed the silc_mutex_alloc interface. It allocates the
3924 mutex now to the sent pointer and returns TRUE or FALSE.
3926 Affected file lib/silcutil/silcmutex.h.
3928 * Wrote the SILC Task Queue interface to support multi-threads.
3929 Affected file lib/silcutil/silctask.[ch].
3931 * Wrote the SILC Scheduler to support multi-threads. Affected
3932 file lib/silcutil/silcschedule.c.
3934 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3936 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3937 in lib/silcutil/win32/.
3939 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3941 * Defined SILC Mutex API and SILC Thread API and implemented
3942 them for Unix. Affected files are
3943 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3944 lib/silcutil/unix/silcunixmutex.c and
3945 lib/silcutil/unix/silcunixthread.c.
3947 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3949 * Fixed the silc_server_remove_clients_by_server's channel
3950 key re-generation. The hash table handling was incorrect
3951 and would not work with many channels. Affected file is
3954 * Fixed some memory leaks around the server code.
3956 * Rewrote the silc_server_get_users_on_channel to support IPv6
3957 based Client ID's. Affected file silcd/server.c.
3959 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3960 specification. However, a separate document must be written
3961 to define the detailed signing procedure and the payload
3962 associated with the flag. Defined the flag to the
3963 lib/silccore/silcchannel.h as well.
3965 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3967 * Changed the dynamic tables to static size tables in the
3968 lib/silccrypt/silchmac.c.
3970 * Removed GCC dependencies from the code. A patch by cras.
3972 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3974 * Do not show the error "Error receiving packet bla bla"
3975 in server if it really was not an error (-2 means that reading
3976 is pending). Affected file silcd/server.c.
3978 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3980 * Fixed a possible crash in silc_server_remove_clients_by_server
3981 in silcd/server.c. Fixed there also some memory leaks.
3983 * Fixed the silc_idlist_replace_client_id. It could replace
3984 wrong key in the hash table. Affected file silcd/idlist.c.
3986 * Do not check whether there are global users on the channel
3987 if the channel->global_users is FALSE. Affected functions
3988 silc_server_remove_from_one_channel and
3989 silc_server_remove_from_channels in silcd/server.c. Also,
3990 do not check if the removed client is local as we can be
3991 sure that global client was not removed from the channel
3992 and checking for global users is not needed.
3994 * The silc_server_remove_clients_by_server now re-generates
3995 the channel keys correctly for those channels that had
3996 clients removed from them. Affected file silcd/server.c.
3998 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4000 * Found the reason of random crashes in the server. We weren't
4001 ignoring the SIGPIPE signal (which can be sent in write())
4002 and it crashed the server. Affected file silcd/silcd.c.
4004 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4006 * Assure that sock->user_data is not NULL in the function
4007 silc_server_packet_send in silcd/packet_send.c.
4009 * Disconnect the remote connection if it could not be added
4010 to any ID lists in the server. The affected file is
4013 * Check in silc_server_packet_send[_real/dest] that the
4014 socket is not disconnecting and ignore the data if it is.
4015 Affected file silcd/packet_send.c.
4017 * Define inline to __inline on native WIN32 compilation.
4018 Affected file includes/silcwin32.h.
4020 * Added some explicit type casts for inline code since MSVC
4021 require them. Affected files lib/silcutil/silcbuffer.h,
4022 lib/trq/silcdlist.h and lib/trq/silclist.h.
4024 * Print warning in log files from now on if the packet
4025 decryption fails. Affected file silcd/server.c.
4027 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4029 * Changed the `say' client operation's interface to accept
4030 new `type' argument to indicate the type of the message sent
4031 by the library. The application may filter the library's
4032 messages according the type. The affected file is the
4033 lib/silcclient/silcapi.h.
4035 * Added two new functions to lib/silcclient/silcapi.h:
4036 silc_client_del_client and silc_client_del_client_by_id.
4037 Affected file lib/silcclient/idlist.c.
4039 * Moved the clientincludes.h from includes/ to silc/ and
4040 serverincludes.h from includes/ to silcd/.
4042 * The modes for the CMODE and CUMODE are now passed as
4043 uint32 for application with COMMAND_REPLY. The affected
4044 file is lib/silcclient/command_reply.c.
4046 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4048 * /WHOIS without arguments shows client's own information.
4049 Affected file lib/silcclient/command.c.
4051 * Changed PING to not accept any arguments. The specs
4052 says that client can ping only the connected server so
4053 requiring an argument is not needed. Affected file is
4054 lib/silcclient/command.c.
4056 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4058 * Fixed a fatal bug in private message sending and reception
4059 encryption and decryption when using private message keys.
4060 The implementation was incorrect and did not follow the
4061 specification. It causd that some of the message were
4062 lost since it did not use the sending and receiving keys
4063 as the protocol suggests. This has been fixed and will cause
4064 incompatibilities with older clients when sending private
4065 message encrypted with private message keys. Affected files
4066 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
4067 and various other in Irssi SILC Client.
4069 Added `responder' boolean argument to the functions
4070 silc_client_add_private_message_key[_ske] to indicate when
4071 the key is added as responder or initiator of the key
4074 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4076 * Removed the silc_ske_check_version function and created
4077 a SilcSKECheckVersion callback. Added also a function
4078 silc_ske_set_callbacks that is now used to set all SKE
4079 callbacks. The callback functions are not given to
4080 the SKE functions anymore, but this function is used to
4083 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
4085 * Added `silc_version' argument to the silc_client_alloc
4086 to define the version of the application for the library.
4087 The library will use the version string to compare it
4088 against the remote host's (usually a server) version
4089 string. Affected file lib/silcclient/silcapi.h
4091 * Added the KE protocol context to Key Agreement context
4092 in client library so that we can abort the SKE if it
4093 is in process when we get timeout. Affected file is
4094 lib/silcclient/client_keyagr.c.
4096 * Do not resolve the client ID forever if it returns in the
4097 first time that such client does not exist. This was done
4098 for example with private message. Affected file is
4099 lib/silcclient/client_prvmsg.c.
4101 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4103 * Do not add regex.h for WIN32. The affected file
4104 includes/silcincludes.h.
4106 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
4107 not work yet 100%. It generates the DLL's automatically
4108 when compiling with --with-win32 under cygwin.
4110 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4112 * lib/contrib/regex.c is not compiled on WIN32.
4114 * Added silc_net_get_socket_opt function to the
4115 lib/silcutil/silcnet.h.
4117 * Added includes/silcwin32.h for WIN32 specific includes
4120 * Do not use ptime structure or any of the posix process
4121 functions on WIN32 in lib/silccrypt/silrng.c.
4123 * Added silc_gettimeofday to provide generic function
4124 for struct timeval on all platforms. Added the function
4125 to lib/silcutil/silcutil.h.
4127 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4129 * Moved the lib/silccore/silcsockconn.[ch] to the utility
4130 library as they clearly belong there. As a plus side we
4131 can make the actual socket connection routines platform
4134 Added also new generic function silc_socket_read and
4135 silc_socket_write (that used to be silc_packet_[read/write].
4136 The implementation of these are platform specific.
4138 * Added WIN32 specific routines of silc_socket_[read/write]
4139 to lib/silcutil/win32/silcwin32sockconn.c.
4141 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4143 * Added preliminary support for native WIN32 compilation under
4144 cygwin (using the -mno-cygwin option for GCC) to the
4145 ./configure.in.pre. The --with-win32 now prepares the
4146 compilation for native WIN32.
4148 * Rewrote the SILC Scheduler interface in the file
4149 lib/silcutil/silcschedule.h. The scheduler is now context
4150 based and does not have anymore any global static scheduler.
4151 Moved the Unix scheduler to the lib/silcutil/unix/ directory
4152 and created lib/silcutil/win32 directory for WIN32 based
4155 * Added Unix specific network routines to the
4156 lib/silcutil/unix/silcunixnet.c and the old
4157 lib/silcutil/silcnet.c includes now only generic routines.
4159 Added WIN32 specific network routines to the
4160 lib/silcutil/win32/silcwin32net.c.
4162 * Added Unix specific utility functions from the
4163 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
4165 * Added WIN32 SILC Scheduler to the file
4166 lib/silcutil/win32/silcwin32schedule.c. The code is of course
4169 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4171 * Do not handle JOIN notify in the server if the target client
4172 is not registered (idata->registered == FALSE). The affected
4173 file is silcd/packet_receive.c.
4175 * Update the nickrec->founder in event_cumode in the Irssi SILC
4176 client. Affected file irssi/src/silc/core/silc-channels.c.
4178 * Fixed the CUMODE_CHANGE notify handling in the server when
4179 server and router are announcing their clients on channels.
4180 Now the mode changes are saved and notified correctly. The
4181 affected file is /silcd/packet_receive.c.
4183 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
4184 They really did not replace the cache entry in the ID Cache.
4185 Now they do that. Affected file silcd/idlist.c.
4187 * Fixed the KICK notify handling in the Irssi SILC client to
4188 update the channel records so that the kicked client does not
4189 appear to be on the channel. The affected file is
4190 irssi/src/silc/core/silc-channels.c.
4192 * Always update the conn->current_channel when executing command
4193 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
4195 * Fixed the KILL notify handling in Irssi SILC client to remove
4196 the killed client on all channels.
4198 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4200 * Fixed the silc_parse_command_line to remove extra spaces
4201 from the start and end of the arguments. Affected file is
4202 lib/silcutil/silcutil.c.
4204 * Cancel and free any active protocol in the function
4205 silc_server_close_connection. Affected file silcd/server.c.
4207 * Cancel and free any active protocol in the function
4208 silc_client_close_connction. Affected file is
4209 lib/silcclient/client.c.
4211 * Do not execute the KILL command for clients that are in
4212 history (ie. they are not in the network). Affected file is
4215 * Fixed KILL notify handling, client does not crash anymore.
4216 Affected file irssi/src/silc/core/silc-channels.c.
4218 * Reduced the default packet buffer size from 2048 to 1024 in
4219 lib/silccore/silcpacket.c.
4221 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
4222 counter to the SKE context that is incresed when the SKE library
4223 performs async operation outside the library. If the outside
4224 process frees the SKE context and FREED status will be set
4225 and the library will detect after the sync operation that the
4226 libary is freed. The affected files are
4227 lib/silcske/silcske[_status].[ch].
4229 * Resolve the client entry information in the function
4230 silc_client_channel_message to assure that NULL pointer is not
4231 passed as client entry to the application. */
4233 * Fixed the task timeout calculation to assure that there is
4234 never negative timeouts. The affected file is
4235 lib/silcutil/silcschedule.c.
4237 * Fixed the channel user mode notification sending in server.
4238 It was sent point-to-point to the router (or to server by router)
4239 but it needs to be destined to a channel. The routines now
4240 supports sending the channel user mode notifys to the channels
4241 when announcing clients and channels. Affected files are
4242 silcd/server.c and silcd/packet_receive.c.
4244 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
4245 It did not actually replace the old channel entry in the cache.
4246 Affected file lib/silcclient/client_notify.c.
4248 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4250 * Fixed a possible crash in silc_packet_send_prepare. It now
4251 assures always that there is enough space in the buffer and
4252 at the tail area of the buffer (for MAC).
4254 Fixed the inbound buffer reallocation in silc_packet_read.
4255 It was old code and did not handle the reallocation correctly.
4258 The affected file is lib/silccore/silcpacket.c.
4260 * Fixed buffer overflow in silc_parse_nickname in the file
4261 lib/silcutil/silcutil.c.
4263 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4265 * make install generates new server keys only if there is not
4268 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4270 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
4271 Added check that if the NOREPLY is set then we will not send
4272 the away message. This avoids infinite loop of away messages
4273 if both clients are away. The affected file is
4274 lib/silcclient/client_prvmsg.c.
4276 * Fixed client crash if /NICK was given without arguments.
4277 Affected file lib/silcclient/command.c.
4279 * Server does not send the invite list in INVITE command back
4280 to the client if the list was not altered. Added this notion
4281 to the protocol spec as well. Affected file silcd/command.c.
4283 Fixed possible crash in INVITE command by checking the
4284 value of silc_server_get_client_route command.
4286 * Fixed the INVITE notify type handling. The arguments are now
4287 taken in correct order and client does not crash. The affected
4288 file is irssi/src/silc/core/silc-channels.c.
4290 Removed the "Inviting xxx to channel" message from the
4291 client library away and let the application handle it.
4292 Affected file lib/silcclient/command.c. Added that message
4293 to Irssi SILC client's message formats.
4295 * Fixed CMODE command crash in client. It now checks the
4296 amount of arguments correctly and does not crash. The affected
4297 file is lib/silcclient/command.c.
4299 * Do not create new channel automatically in silc_channels_join
4300 but check whether the channel by that name already exists.
4301 Affected file irssi/silc/core/silc-channels.c.
4303 * Do not send the SERVER_SIGNOFF to router if the disconnected
4304 entity was the router. Affected file silcd/server.c.
4306 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
4307 SILC client as it was missing from there.
4309 Added the handling of the KICK notify to the Irssi SILC client
4310 as it was missing. Added "you have been kicked" message to
4311 Irssi SILC client's message modules formats.
4313 Added the handing of the KILL notify to the Irssi SILC client
4314 as it was missing. Added the kill message module formats
4317 The affected file is irssi/src/silc/core/silc-channels.c.
4319 * The router did not save the channel mode the server announced.
4320 Affected file silcd/packet_receive.c.
4322 * Fixed a possible crash in INFO command in server. If the
4323 server did not provide the server info it crashed. Affected
4324 file silcd/command.c.
4326 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4328 * Fixed the GETKEY command in the server to check also the
4329 global list. Otherwise the GETKEY would not work correctly
4330 in normal SILC server. Affected file silcd/command.c.
4332 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4334 * Fixed GETKEY crash, it crashed if the command did not succseed.
4336 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4338 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
4339 is now real and not just an macro interface to GMP.
4341 Removed the entire GMP from the source tree and imported new
4342 NSS MPI library instead. Reason for removing GMP is that it is
4343 extremely large and compiles extremely slow. The NSS MPI
4344 is only a few files and compiles in less than 10 seconds.
4345 The speed is also about the same as GMP. The MPI is imported
4346 to lib/silcmath/mpi.
4348 If the system has GMP installed we will still use the GMP.
4349 If it is not then the NSS MPI will be compiled.
4351 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4353 * Merged a long nickname (127 characters long) crash bugfix from
4354 Irssi CVS tree. Affected file irssi/src/core/misc.c.
4356 * Merged a freed memory reference bugfix from Irssi CVS tree.
4357 Affected file irssi/src/core/commands.c.
4359 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4361 * Added the server's public key sving and verification to the
4362 server when performing the SKE. This was missing and the
4363 remote server's (or router's) public key was accepted without
4364 checking whether we have it previously or trust it at all.
4365 Affected file silcd/protocol.c.
4367 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4369 * Check in the silc_server_timeout_remote if protocol is active
4370 and make sure that the protocol's final callback is called so
4371 that all memory if freed. Affected file silcd/server.c.
4373 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4375 * silc_server_whois_send_reply crashed the server if the nickname
4376 was 127 characters long. Affected file silcd/command.c.
4378 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4380 * Added sanity check to the silc_server_new_client. If the hostname
4381 is provided inside username then check that the provided hostname
4382 really is the same as the resolved one. If the hostname was not
4383 resolved then check it from the public key. Affected file is
4384 silcd/packet_receive.c.
4386 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
4387 if the server disconnected us and the connection is not valid
4388 anymore. Affected file irssi/src/silc/core/silc-channels.c.
4390 * Moved the silc_client_[chmode|chumode|chumode_char] away from
4391 the library to the lib/silcutil/silcutil.[ch].
4393 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4395 * Close log file after open. Affected file
4396 lib/silcutil/silclog.c.
4398 * Check whether sock == NULL in silc_client_send_packet and return
4399 if it is. Affected file lib/silcclient/silcclient.c.
4401 * Check rec->entry == NULL in the Irssi SILC Client before
4402 sending the channel message. Affecte file is
4403 irssi/src/silc/core/silc-servers.c.
4405 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4407 * Merged a splitted window bugfix from Irssi CVS tree. The
4408 affected file is irssi/src/fe-text/textbuffer-view.c.
4410 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
4411 It did not print nickname.
4413 * Improved the distributions system a bit.
4415 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4417 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
4418 irssi/src/fe-text/gui-window.c.
4420 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
4421 to in-active server. The affected file is
4422 irssi/src/silc/core/client_ops.c.
4424 * Resolve the client in USERS command reply if the entry does
4425 not have username resolved. The affected file is
4426 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
4427 command to WHOIS command to really resolve stuff. The USERS
4428 is not used any more in any critical section so WHOIS can
4429 be used even though it might be slower than IDENTIFY.
4431 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
4434 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4436 * Changed the protocol API a bit more consistent in the
4437 lib/silccore/silcprotocol.[ch].
4439 * Changed the following headers to ROBODoc format:
4441 lib/silccore/silcpayload.h
4442 lib/silccore/silcprotocol.h
4443 lib/silccore/silcsockconn.h
4445 All core library headers are now formatted.
4447 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4449 * Fixed a bug in Irssi SILC client; do not show that you are
4450 server/router operator if you really are not. Affected file is
4451 irssi/src/silc/core/client_ops.c.
4453 * Renamed silc_command_free_payload to silc_command_payload_free.
4454 Affected file lib/silccore/silccommand.h
4456 * Added silcmath.h to include the prototoypes of various routines
4457 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
4460 * Changed the following headers to ROBODoc format:
4462 lib/silccore/silcchannel.h
4463 lib/silccore/silccommand.h
4464 lib/silccore/silcid.h
4465 lib/silccore/silcidcache.h
4466 lib/silccore/silcmode.h
4467 lib/silccore/silcnotify.h
4468 lib/silccore/silcpacket.h
4469 lib/silcmath/silcmath.h
4471 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4473 * Added checking to the server code not to start the server if
4474 ciphers and stuff are not configured properly. Affected files
4475 silcd/serverconfig.[h] and silcd/server.c.
4477 * Changed the layout of the header files of the public interfaces
4478 in the SILC libraries. The new layout supports ROBODoc
4479 documentation tool (and some others) so that it is easy to create
4480 a library reference manual. All the other headers and source
4481 code must still follow the CodingStyle document. Also source
4482 code must not include these ROBODoc stuffs, only the headers.
4483 Furthermore, all public interface headers must now be named
4484 by using `silc' prefix, example: silcapi.h, silccipher.h.
4485 Some files were renamed due to this. All the other headers
4486 must not be used as public interfaces. I will update the
4487 CodingStyle document later. Changed following headers, so far:
4489 lib/silcclient/silcapi.h
4490 lib/silccore/silcauth.h
4491 lib/silccore/silcprivate.h
4492 lib/silccrypt/silcdh.h
4494 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4498 * Removed silc_client_packet_send_flush from the client library
4499 as it is not needed. Affected file lib/silcclient/client.[ch].
4501 * Added printing of message of unresolved authentication method
4502 to the Irssi SILC client. Added it to the module formats.
4503 Removed the same message from the client library.
4505 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4507 * Added new distribution feature, DISTLABEL. Every distribution
4508 can define own preprocessor label that can be used in the
4509 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
4510 file distributions, acconfig.h.pre and prepare.
4512 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4514 * Added Makefile.defines_int to include the actual definitions
4515 for Makefile.defines.in. Tested the new distribution system,
4516 created distributions and tested installation.
4518 * Added AWAY message printing to the Irssi SILC client. Added
4519 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
4521 * Added SCONNECT command to call the SILC's CONNECT command.
4522 Cannot use CONNECT directly since Irssi uses that internally.
4523 Affected file irssi/src/silc/core/silc-servers.c.
4525 Added ACTION local command. It is same as ME command but takes
4526 the channel as mandatory argument.
4528 Rewrote some of the Irssi's help files to suite for SILC
4531 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4533 * Added Makefile.defines[.in] that should for now on be included
4534 in all Makefile.am file in the source tree. That file includes
4535 all common compilation definitions for SILC source tree.
4537 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4539 * Minor changes to the ./prepare script to change the package
4540 name according the distribution name to the configure.in.
4542 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4544 * Created new distribution system. Added file `distributions'
4545 that defines all the distributions that can be created out of
4546 the SILC source tree. The ./prepare script now reads that
4547 file to determine how to prepare the distributions. The
4548 first argument to the ./prepare is the name of the distribution
4549 and second is the version of the distribution. If given
4550 without arguments it creates the default (toolkit) distribution
4551 with the default version (defined in ./prepare).
4553 All Makefile.am files that are subject to the distributions
4554 are now named as Makefile.am.pre. These are ./Makefile.am
4555 and lib/Makefile.am. Others may be changed later.
4557 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4559 * Added invite list, ban list, some key management and connection
4560 error message printing to module formats in the Irssi SILC client.
4562 * Added new silc_client_set_away_message to set the away message
4563 that is back to the person who sent private message. The
4564 affected file lib/silcclient/silcapi.h and the
4565 lib/silcclient/client_prvmsg.c.
4567 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4569 * Fixed the private message sending in the Irssi SILC client,
4570 added local command KEY to the Irssi SILC client.
4572 Added key management and key agreement message formats to the
4573 irssi/src/fe-common/silc/module-formats.[ch].
4575 Added USERS (alias WHO) printing, server/router operator
4576 indication and LIST command printing to the module formats.
4578 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4580 * Fixed channel joining notify handling, cumode notify handling
4581 from Irssi SILC client.
4583 * Added SILC specific module-formats to the Irssi SILC client so
4584 that SILC specific message hilighting, colors etc is possible.
4585 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4587 Added channel mode, channel user mode, actions, notices,
4588 whois and whowas printing to the the module-formats.c.
4590 * Fixed a bug in channel deletion in the server. The channel
4591 is not left to the cache even if the channel founder auth mode
4592 is set when there are no users anymore on the channel. Affected
4593 file silcd/server.c.
4595 * The silc_net_localhost now resolves the entire hostname including
4596 the domain name. Affected file lib/silcutil/silcnet.c.
4598 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4600 * Changed the ask_passphrase client operation to be ascynchronous.
4601 It has now a completion callback and a context that the
4602 application must call after it has got the passphrase from
4603 the user. Affected files lib/silcclient/silcapi.h,
4604 lib/silcclient/protocol.c, lib/silcclient/command.c and
4607 Added SilcAskPassphrase callback that the application calls
4608 to deliver the passphrase to the library.
4610 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4611 The public key verification and especially a certificate
4612 verification is asynchronous procedure.
4614 Added new SILC_SKE_STATUS_PENDING status to indicate the
4615 request is pending and a callback will be called to finalize
4618 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4619 indicate that remote end did not send its public key (or
4620 certificate), even though we require it. Added check for this
4621 condition in the SKE. This was a security bug, now fixed.
4623 Defined new SilcSKEVerifyCbCompletion callback that is called
4624 when the verification process is completed.
4626 The affected files lib/silcske/silcske_status.h and
4627 lib/silcske/silcske.[ch].
4629 * Changed the verify_public_key client operation to be async
4630 as well. Defined SilcVerifyPublicKey callback that is used to
4631 indicate the success of the public key verification process.
4633 Changed the server and client to use the new async client
4636 * Changed the Irssi SILC client's internal scheduler to be called
4637 twice as many times as it used to be. As a result the client
4638 should be a bit faster now. Affected file is
4639 irssi/src/silc/core/silc-core.c.
4641 * Added support to Irssi SILC client of asynchronous public key
4642 verification and passphrase inquiry. Affected file is
4643 irssi/src/silc/core/silc-core.c.
4645 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4647 * Do not say "You have left channel %s" in client library.
4648 Moved it to the application. Affected files are
4649 lib/silcclient/command.c and silc/client_ops.c.
4651 * Fixed silc_client_get_clients. Command context was not
4652 duplicated and was freed memory in the callback. Affected
4653 file lib/silcclient/idlist.c.
4655 * Do not say "you are now talking..." on JOIN command in the
4656 client library. The appliation must handle it.
4658 * Do not say ".. changed topic to" in command reply in the
4659 client libary. The application must handle it.
4661 * Fixed TOPIC command sending in the client library.
4663 * Fixed a memory leak in silc_client_command_free in the file
4664 lib/silcclient/command.c.
4666 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4668 * Imported a modified version of Irssi client to the source tree.
4669 The Irssi will be used to create a new client called
4670 Irssi SILC. Imported to irssi/.
4672 Added silc_core_init_finish function to the Irssi. Affected
4673 file irssi/configure.in.
4675 A lot changes in the Makefile.ams around the irssi tree.
4677 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4679 * Do not rehash if the new size is same as the old size of the
4680 hash table, in the silc_hash_table_rehash*. The affected file
4681 lib/silcutil/silchashtable.c.
4683 * Replaced hash_table_del_by_context calls from the server
4684 (when channel->user_list and client->channels) to the
4685 hash_table_del as it is sufficient and faster.
4687 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4689 * Added silc_hash_table_list, silc_hash_table_get and the
4690 SilcHashTableList structure to provide an alternative way to
4691 traverse the hash table. The affected files are
4692 lib/silcutil/silchashtable.[ch].
4694 * Changed the server's idlist routines to use the hash table
4695 routines to optimize the code.
4697 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4699 * Replaced the client entry's `channel' list and channel entry's
4700 `user_list' list to hash tables for optimized lookup. Changed
4701 the code to use the hash table interface around the code.
4702 Affected file lib/silcd/idlist.[ch].
4704 * Added `auto_rehash' boolean argument to the function
4705 silc_hash_table_alloc to indicate whether the hash table should
4706 auto-rehash when it thinks is appropriate time. It will
4707 increase the hash table size if the there is twice as much
4708 entries in the table than the size of the table, and will
4709 decrease the size if there are twice as less entries than
4710 the size of the table.
4712 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4714 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4716 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4718 * silc_idcache_purge_by_context deletes the entry now by context
4719 as it is supposed to do. Affected file lib/silccore/idcache.c.
4721 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4722 client is not anymore valid (WHOWAS givens the info) and not
4723 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4725 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4727 * Removed the `data' and `data_len' arguments from the ID Cache
4728 interfaces and added `name' argument. ID Cache does not handle
4729 anymore the binary data only a names associated with given ID.
4731 * When hashing a Client ID with silc_hash_id the entire ID is
4732 not hashed anymore, instead only the hash of the Client ID is
4733 hashed. This way we can access the Client ID from the cache
4734 with Client ID but with the hash of the ID (which is a hash of
4735 the nickname) as well without any difference in performance.
4737 Added also silc_idcache_find_by_id_one_ext to do one on one
4738 searching when we have the actual ID. Added also function
4739 silc_hash_client_id_compare. The affected files are
4740 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4742 * When hashing the name associated with a ID it is always done
4743 in lowercase. This way we can access the cache without worrying
4744 about case-sensitivity, even though, for example nicknames are
4747 * Fixed a bug in server with channel message sending. It put
4748 wrong ID type as destination ID. The affected file
4749 silcd/packet_send.c.
4751 * silc_idcache_del_by_context now deletes from all hash tables
4752 by context. Affected file lib/silccore/idcache.c.
4754 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4756 * Changed the client library to use the new ID Cache interface.
4757 Changes around the source tree.
4759 * Added silc_hash_table_rehash_ext to rehash with specific
4760 hash function. Affected file lib/silcutil/silchashtable.[ch].
4762 * Added silc_hash_string_compare to compare two strings in the
4763 hash table. Affected file lib/silcutil/silcutil.[ch].
4765 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4767 * Added new function silc_idcache_del_by_context into the
4768 lib/silccore/idcache.[ch].
4770 * Changed the server's ID list routines to use the new ID Cache
4771 interface. Changes around the source tree.
4773 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4775 * Added silc_hash_table_del[_by_context]_ext functions in to the
4776 lib/silcutil/silchashtable.[ch].
4778 Removed silc_hash_table_find_all* routines and added new
4779 silc_hash_table_find_foreach to replace them.
4781 Added silc_hash_table_replace_ext function as extended
4782 replacing function. Separated the simple hash table interface
4783 from the extended hash table interface in the file
4784 lib/silcutil/silchashtable.h.
4786 * Fixed minor bugs and changed it to use some of the new
4787 hash table functions in lib/silccore/idcache.c
4789 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4791 * Added new function silc_hash_table_find_all to return all keys
4792 in the hash table by the specified key. As the hash table is
4793 collision resistant it also makes it possible to have several
4794 duplicate keys in the hash table. This function may be used to
4795 find all of the keys from the hash.
4797 Added user_context arguments to the SilcHashFunction,
4798 SilcHashCompare and SilcHashDestructor to deliver user specified
4801 Added new fuctions silc_hash_table_find[_all]_ext to do
4802 extended lookup with specified hash and compare functions and
4803 specified user contexts.
4805 Added new function silc_hash_table_add_ext to add the key
4806 with specified hash function and user context.
4808 Added new function silc_hash_table_foreach to traverse all
4809 entrys in the hash table. Added SilcHashForeach callback
4812 Added new function silc_hash_table_del_by_context to delete
4813 the entry only if the context associated with the key matches.
4815 Affected files are lib/silcutil/silchashtable.[ch].
4817 * Removed silc_hash_[server/client/channel]_id and added just
4818 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4819 silc_hash_id_compare to compare two ID's using as the hash table
4820 comparison function. Added also silc_hash_data to hash
4821 binary data and silc_hash_data_compare to compare it.
4823 * Removed silc_idlist_find_client_by_hash as it is not needed
4824 anymore. Affected file silcd/idlist.[ch].
4826 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4827 to use internally the SilcHashTable. The new ID Cache is a lot
4828 faster than the old one. Some of the ID Cache interface was also
4829 rewritten and obsolete and stupid functions were removed.
4831 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4833 * Added entry_count field to the SilcHashTable to keep the number
4834 of the entries in the table. Implemented the function
4835 silc_hash_table_rehash. Added new function
4836 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4838 Fixed a minor bug in silc_hash_table_free.
4840 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4841 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4842 into the lib/silcutil/silcutil.[ch].
4844 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4846 * Implemented a collision resistant hash table into the
4847 lib/silcutil/silchashtable[ch]. See the header and the source
4848 for the SilcHashTable API.
4850 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4852 * Merged dotconf version 1.0.2 into lib/dotconf.
4854 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4856 * Do not compile anything in lib/silcsim/* if the SIM support
4857 is not enabled. The tree should now compile without problems
4860 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4862 * Compiled the SILC under cygwin. Compiled and tested briefly
4863 without problems. More tests needed. The SIMs didn't compile
4866 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4868 * Fixed possible crash in silc_get_username in the
4869 lib/silcutil/silcutil.c.
4871 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4873 * Fixed a va_arg in silc/client_ops.c.
4875 * Oops, RC5 routines were named AES and caused some problems
4876 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4878 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4880 * Added new SilcIDIP structure into the lib/silccore/id.h and
4881 replaced the old `ip' fields from all SILC ID's to that type.
4882 This is a step towards IPv6 support.
4884 The silc_id_get_len takes now the ID as an extra argument.
4885 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4886 both IPv4 and IPv6 based ID's.
4888 The affected files are lib/silccore/id.[ch] and other files
4889 around the tree using these routines.
4891 * Removed the ID length arguments in server from various
4892 silc_server_send_notify_* routines -> they are not needed
4895 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4897 * Fixed memory leak in silc_encode_pem_file in the file
4898 lib/silcutil/silcutil.c.
4900 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4902 * Check minor version as well in the SKE. Affected files are
4903 silcd/protocol.c and lib/silcclient/protocol.c.
4905 * Added --identifier option to the server so that an identifier
4906 can be when creating the public key for the server. Affected
4907 file is silcd/silcd.c.
4909 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4910 lib/silccrypt/silcpkcs.c.
4912 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4914 * Register default ciphers and stuff when using -C option with
4915 the server. Affected file sildc/silcd.c.
4917 * Put back the servers public key filename format, it is better
4918 than the new one. For now, the client keys are saved with the
4919 new filename format. The affected file silc/client_ops.c.
4921 * Implemented the Cipher API for the rest of the ciphers that
4922 did not implement it or implemented it the wrong way.
4924 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4926 * Register default ciphers and stuff when using the -S option
4927 in the client. Affected file silc/silc.c. Same also when
4928 creating new key pair with -C option.
4930 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4932 * Fixed the silc_verify_public_key client operation function to
4933 save the public keys differently. The fingerprint is now
4934 used as filename and not the hostname. This way also the
4935 client keys are saved uniquely and not with hostnames. The
4936 affected file is silc/client_ops.c.
4938 * Trimmed the silc_hash_fingerprint function to remove extra
4939 whitespaces from the end of the fingerprint. The affected
4940 file is lib/silccrypt/silchash.c.
4944 * Added silc_cipher_register_default function to register all
4945 default ciphers. It can be used when configuration files
4946 does not exist and the application does not want any specific
4947 ciphers in any specific order.
4949 The SilcDList is now used as silc_cipher_list dynamically
4950 allocated cipher list. Removed the static list all together
4951 and now all ciphers must be allocated to the dynamic list.
4952 The silc_cipher_alloc routine was changed to check only the
4955 All silc_cipher_* routines that used to return int returns
4958 The affected files lib/silccrypt/silccrypt.[ch].
4960 * The same thing was done to silc_hash_* as for silc_cipher_*
4961 routines. Affected files lib/silccrypt/silchash.[ch].
4963 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4964 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4965 Added also silc_pkcs_[un]register[_default] functions.
4966 Removed the data_context from the PKCS API.
4968 * Added silc_hmac_register_default function to register default
4969 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4970 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4971 to unregister all hmacs at once.
4973 * Register the default ciphers, hash functions, PKCSs and HMACs
4974 if client's configuration file does not exist. The affected
4977 * The client did not load the hash functions from the SIM
4978 modules at all. Added support for this. Affected file is
4979 silc/clientconfig.c.
4981 * When decoding public key with silc_pkcs_public_key_decode, check
4982 the supported algorithm only if PKCS are registered. Affected
4983 file lib/silccrypt/silcpkcs.c. The same was done with the
4984 silc_pkcs_private_key_decode.
4986 * Fixed the SILC List routines to keep the list always in order.
4987 It used to change the list's order when traversing the list but
4988 not it preserves the order. Affected file lib/trq/silclist.h.
4990 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4992 * Added the client library to use the SilcSocketConnection's
4993 reference counter (by silc_socket_dup) to prevent the bug that
4994 the socket object may be freed underneath async operation.
4996 * The name resolv library checking fixes in the configure.in.pre.
4999 * Created new version of the protocol drafts for future
5000 development. The -03 drafts are the ones that will be changed
5001 in the trunk now and the -02 will remain as they are.
5003 * Send list of CUMODE notifys to the router when announcing
5004 the channel users to the router. Affected file silcd/server.c.
5005 If the router receiving channel founder CUMODE for a channel
5006 that already has channel founder it will send CUMODE notify
5007 to the sender to remove the channel founder rights from the
5008 announced client. Affected file silcd/packet_receive.c.
5010 * The CUMODE notify may now use Server ID as well as the entity
5011 who changes the mode. Updated protocool specs.
5013 * Updated INSTALL and README files.
5015 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5017 * New web pages in the http://silc.pspt.fi. The pages was
5022 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5024 * Implemented the [DenyConnectin] config section in the server.
5025 Added silc_server_config_denied_conn to check whether incoming
5026 connection is denied. Affected file silcd/serverconfig.[ch].
5028 * Do not check the ports when checking the incoming configuration
5029 data if the port is 0, meaning any. Affected file is
5030 silcd/serverconfig.c.
5032 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5034 * Fixed buffer overflow in silc_string_compare in the file
5035 lib/silcutil/silcutil.c.
5037 * Fixed double free in silc_server_command_leave in the file
5040 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5042 * Fixed the version checking in the server. Affected file is
5045 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5047 * Fixed the configuration data fetching when accepting new
5048 connections in the server. Affected file silcd/server.c.
5050 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5052 * Added `sender_entry' argument to the function
5053 silc_server_packet_relay_to_channel so that we can check
5054 whether some destination actually belongs to the same route
5055 the sender belongs (ie, we must not resend the packet to the
5056 sender). Affected file silcd/packet_send.[ch].
5058 * Added `servername' field to the SilcClientEntry in the server
5059 to hold the name of the server where client is from. Affected
5060 file is silcd/idlist.h.
5062 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5064 * Moved the channel message encrypting in the router betwen
5065 router connections from silc_server_channel_message to the
5066 silc_server_packet_relay_to_channel since we want to check
5067 whether we have anybody channel before encrypting anything.
5068 Affected files silcd/packet_[receive/send].c.
5070 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5072 * Fixed the [AdminConnection] server config section to support
5073 multiple entries. Affected file silcd/serverconfig.c.
5075 * Added support into the server to check the validity of the
5076 incoming connection before executing any KE or authentication
5079 * The connection configuration is now saved to the KE and
5080 connection auth protocol contexts and not fetched anymore in
5081 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
5083 * The local hosts listenning address and port is also resolved
5084 now when starting the server. We want to have the socket object
5085 to include the real address and port for the listener. Added
5086 new function silc_net_check_local_by_sock into the files
5087 lib/silcutil/silcnet.[ch].
5089 * Fixed a broadcast bug in server -> do not broadcast if we
5092 * Fixed a routing bug. Do not route broadcast packets ever.
5093 Broadcast packets must be processed always and not routed since
5094 they may be destined to some other host than yourself and thus
5095 would get routed without no good reason. Affected file is
5098 * Added function silc_server_config_is_primary_route to check
5099 whether primary router connection has been configured (a router
5100 configuration that we are initiating). If there is not, we
5101 will assume that there is only two routers in the SILC network
5102 and we will use the incoming router connection as our primary
5103 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
5105 * Changed the order of the broadcasting. Broadcast _after_ the
5106 packet has been processed not before. Affected file is
5109 * Fixed a [ClientConnection] parsing bug. The port was never
5110 parsed correctly thus resulting to port 0. Affected file
5111 silcd/serverconfig.c.
5113 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
5114 argument and did not set the broadcast packet flag. Affected
5115 file silcd/packet_send.c. Fixed same bug in the function
5116 silc_server_send_notify as well.
5118 * If we receive NEW_ID packet for our own ID in the server, ignore
5121 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5125 * Removed the nickname from the Private Message Payload.
5126 Updated the code and the protocol specs.
5128 * Updated protocol specs for submitting to the IETF.
5130 * Tweaked the Random Number Generator a bit. Affected file
5131 lib/silccrypt/silcrng.c. Exported a new function
5132 silc_rng_[global]_add_noise which can be used to add more
5135 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5137 * Do not parse packets with different timeout when protocol
5138 is active -> may cause problem with rekey. Affected file
5141 * When server receives signoff notify it must not create
5142 new channel key if the client is on any channels since the
5143 sender of the signoff notify will create it.
5145 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5147 * Added printing of error messages during SKE protocol from the
5148 failure packet sent by server during SKE. Affected file
5151 * Removed the client's failure_callback handling with timeout
5152 and handle it immediately when received.
5154 * The SKE library returned wrong type in SUCCESS and FAILURE
5155 packets. They must be 32 bit MSB not 16 bit MSB.
5157 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5159 * Ok, rewrote the logic of the re-key and now it seems to work.
5160 I tested it on high traffic with frequent re-keys without
5161 problems. Added hmac_receive (and renamed hmac to hmac_send)
5162 in SilcClientConnection in lib/silcclient/client.h and
5163 in SilcIDListData in silcd/idlist.h. Also, removed the
5164 SilcPacketParserContext's cipher and hmac fields as they are
5165 not needed anymore and actually caused some problems when
5166 the ciphers and hmac's changed underneath the packet parser.
5168 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5170 * If re-key protocol is active then process the incoming packets
5171 synchronously since we must assure that icoming packets encrypted
5172 with the old key is processed before the new keys is set to
5173 use. This is true other packets than for REKEY packets.
5174 Affected file silcd/server.c. The same was done to client library
5175 as well, affected file lib/silcclient/client.c.
5177 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5179 * Fixed bug in client and server to accept the force send if
5180 the packet is send from silc_[server/client]_packet_process
5181 function. Otherwise the packets are never delivered, oops.
5183 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5185 * Disable force sending of packets when REKEY protocol is active.
5186 We must assure that no packet is sent directly when rekey is
5187 performed. All packets must be sent through packet queue.
5188 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
5189 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
5190 function is silc_[server/client]_packet_send_real to check
5193 * Replaced the SIM paths from example config files to
5194 /usr/local/modules. Also, make install creates now
5195 /usr/local/silc/logs directory to hold all the SILC server
5198 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5200 * Made the configure.in.pre work on Solaris. Patch by salo.
5202 * Made all ciphers compatible with non-x86 machines. Defined
5203 CBC mode macros into lib/silccrypt/ciphers_def.h.
5205 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5207 * Fixed the make install.
5209 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5211 * When MAC computation fails the silc_packet_decrypt returned 0
5212 even though it was supposed to return -1. Fixed this. The
5213 affected file is lib/silccore/silcpacket.c.
5215 * Do not replace the config files in /etc/silc (in make install)
5216 if they already exist. Affected file ./Makefile.am.
5218 * Do not send re-key packets immediately but through packet queue.
5219 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
5221 * Changed silc_net_check_host_by_sock to return FALSE if the
5222 IP/DNS could not be resolved. Though, it returns the IP address
5223 now even if it could not resolve it (but returns also FALSE).
5224 Affected file lib/silcutil/silcnet.[ch].
5226 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5228 * Added silc_pkcs_decode_identifier to decode the public key's
5229 identifier. Affected file lib/silccrypt/silpkcs.[ch].
5230 Added also silc_pkcs_free_identifier. Added also new context
5231 SilcPublicKeyIdentifier.
5233 * Added -S option to the silc client. It is used to dump the
5234 contents of the specified public key file.
5236 * Changed the PKCS api to return the public key length when
5237 setting the public key.
5239 * Fixed a fatal bug in the public and private key file loading.
5240 Affected file lib/silccrypt/silcpkcs.c.
5242 * Execute the packet parsing for client with zero (0) timeout
5243 if the protocol is active. Affected file silcd/server.c.
5245 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5247 * Made the key generation options to the silcd program. Added
5248 -C option, equivalent to client's option.
5250 * Added new [ServerKeys] config section to the server. It
5251 configures the server's public and private key.
5253 * Defined generic Public Key Payload into the protocol
5254 specification to send specific type of public keys and
5257 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
5258 public key or certificate.
5260 * Implemented the GETKEY command to the server and to the
5261 client library and on user interface.
5263 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5265 * Made preliminary `make install' work.
5267 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5269 * Added SilcServerRekey context into silcd/idlist.h.
5271 * Added the PFS support as defined in the specification to the
5272 SKE protocol. Affected files lib/silcske/*.c.
5274 * Added `ske_group' field to the SilcServerRekey context to hold
5275 the number of the SKE group that is used with PFS in re-key.
5276 Affected file silcd/idlist.h.
5278 * Added PFS re-key support to the server. Affected file is
5281 * Added silc_protocol_cancel to cancel execution of the next
5282 state of the protocol. Affected file is
5283 lib/silccore/silcprotocol.[ch].
5285 * Added the re-key support with and without PFS to the client
5286 library. Re-key is performed once in an hour, by default.
5288 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
5289 Added silc_client_rekey_callback and silc_client_rekey_final.
5290 Affected files are lib/silcclient/protocol.[ch] and
5291 lib/silcclient/client.[ch].
5293 * Removed the `hmac_key' and `hmac_key_len' fields from the
5294 SilcClientConnection structure; not needed. Affected file is
5295 lib/silcclient/client.h.
5299 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5301 * Do not ask whether user wants to use the negotiated private key
5302 for private messages, just use it. Affected file is
5303 silc/local_command.c.
5305 * Added `send_enc_key' and `enc_key_len' fields to the
5306 SilcIDListData structure since they are needed in the re-key
5307 phase. Affected file is silcd/idlist.[ch].
5309 * Implemented the simple re-key protocol into the server.
5310 Affected files silcd/server.c and silcd/protocol.[ch]. The
5311 re-key will be performed once in an hour, by default.
5313 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
5314 Added silc_server_rekey, silc_server_rekey_callback and
5315 silc_server_rekey_final.
5317 * Removed Tunneled flag from the protocol. Updated the code
5318 and the specifications.
5320 * Adde `pfs' field to the SilcIDListData to indicate whether
5321 the PFS is to be performed in the re-key. Affected file is
5324 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5326 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
5327 int64 of at least the xintXX size. If void * is less that 4
5328 bytes uint32 * will be used. Defined bool as boolean.
5330 * Changed _ALL_ unsigned long and unsigned int to uint32,
5331 unsgined short to uint16 in the source tree.
5333 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
5334 not handle clients that has entry->data.registered == FALSE.
5335 They are not in the network anymore. Affected file is
5338 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5340 * Implemented the sending of the SERVER_SIGNOFF notify in the
5341 server. Affected file is silcd/server.c.
5343 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
5344 Added also silc_notify_payload_encode_args into the
5345 lib/silccore/silcnotify.[ch].
5347 * Implemented ther SERVER_SIGNOFF notify handling in the server.
5348 Affected file silcd/packet_receive.c.
5350 * Implemented the SERVER_SIGNOFF notify handling in the client
5351 library. Affected file lib/silcclient/client_notify.c. Also,
5352 implemnted the printing of the SERVER_SIGNOFF info to the
5353 application. Affected file silc/client_ops.c.
5355 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
5356 if the deleting was successful. Affected file silcd/idlist.[ch].
5358 * Added support for public key authentication in the connection
5359 authentication protocol in the client library. Affected file
5360 lib/silcclient/protocol.c.
5362 * Changed the server's silc_idlist_get_clients_by_* interface
5363 to support already allocated array so that new entries may be
5364 added to pre-allocated array. Affected file silcd/idlist.[ch].
5365 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
5366 and command replies.
5368 * All command reply functions in the server now calls the
5369 pending command callback even if error occured. This way the
5370 error will be delivered to the client as well. Affected files
5371 silcd/command.c and silcd/command_reply.c.
5373 * Fixed INFO command to return local server's info if no server
5374 was provided. Affected file lib/silcclient/command.c.
5376 * Removed RESTART command for good. Updated the code and the
5379 * Rewrote parts of the task system. It is a bit simpler now.
5380 Removed unsued task priorities. The affected files are
5381 lib/silcutil/silctask.[ch].
5383 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5385 * Moved the USERS printing from the library to the application.
5386 Affected files lib/silcclient/command.c and silc/client_ops.c.
5388 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5392 * Added channel key re-key support. The re-key is perfomed
5393 only by the router and is done once in an hour. Added `rekey'
5394 field to the SilcChannelEntry in the server. Affected files
5395 silcd/server.c and silcd/idlist.h.
5397 * Added silc_task_unregister_by_context into the file
5398 lib/silcutil/silctask.[ch].
5400 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5402 * Added SILC_UMODE_GONE mode to indicate when the client is not
5403 present in the SILC network. Added also support to the local
5404 command AWAY that will set this mode. Added support of showing
5405 "xxx is gone" in WHOIS command. The USERS command shows the
5406 gone status as well.
5408 * Fixed setting server and router operator privileges in the
5409 server's UMODE command. Affected file silcd/command.c.
5411 * Merged the SKE KE1 and KE2 payloads into one payload. The
5412 new KE payload is equivalent to the old KE2 payload.
5414 Cleaned up the SKE Start Payload parsing. It now uses the
5415 simple buffer unformatting to do the parsing. A lot faster
5418 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
5419 to the SKE that is used to indicate whether both of the SKE
5420 parties should perform authentication. By default only the
5421 responder performs authentication. By setting this flag also
5422 the initiator must do authentication. By default it is unset
5423 since in normal SKE case, client to server connection, only
5424 the responder should do authentication. When doing SKE between
5425 two clients both should perform authentication. Updated the
5426 code and the protocol specs.
5428 * A little fix to IDENTIFY command in the server. Search the
5429 client first by hash not nickname. Affected file is
5432 * Fixed the silc_client_close_connection to support closing
5433 the client to client connections wihtout deleting too much
5434 data. Affected file lib/silcclient/client.c.
5436 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
5437 are received if protocol used to be active but is not anymore
5438 the application would crash due to NULL pointer dereference.
5439 Affected files silcd/server.c and lib/silcclient/client.c.
5441 * Added `hash' field to the SilcClientConnection to include
5442 the hash function negotiated in the SKE protocol.
5444 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
5445 to set the channel founder authentication data. A client can
5446 claim the founder rights later by providing the authentication
5447 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
5448 This way the channel founder can regain the channel founder
5449 privileges even it is left the channel. This works only on
5450 local server and the client must be connected to the same
5451 server to be able to regain the founder rights. Updated the
5452 protocol specs accordingly.
5454 Added support to the CMODE command in the client to set the
5455 founder auth data. Read the README to see how to set it.
5457 Added support to the CUMODE command to claim the founder
5458 rights. Read the README to see how to do it.
5460 Added support for the founder authentication to the Channel
5461 Entry in the server. Affected file silcd/idlist.h.
5463 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
5464 server's CMODE command. Affected file silcd/command.c.
5466 * Added the following new functions into lib/silccore/silcauth.[ch]:
5467 silc_auth_get_method and silc_auth_get_data.
5469 * The server now saves the remote hosts public key to the
5470 SilcIDListData pointer. Affected file silcd/protocol.c.
5472 * The normal server now does not remove the channel entry from
5473 the cache if the founder authentication data is set. It used
5474 to remove it if the founder was the last one on the channel on
5475 the server and left the channel. The auth data is saved and
5476 if the channel is re-joined later the old entry is used with
5477 the old auth data. Affected files silcd/command_reply.c and
5480 * Removed the `pkcs' field from the SilcIDListData structure
5481 in the server; it is not used. Affected file silcd/idlist.h.
5483 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5485 * Fixed packet processing on slow links. Partial packets were
5486 never re-processed because the incoming data buffer was cleared
5487 by the application. Application must not directly clear the
5488 sock->inbuf, the packet processing routines handle it. Fixed
5489 this in client library and in server.
5491 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5493 * Fixed the WHOIS and IDENTIFY send reply function to really
5494 check whether to send list or just one entry. Affected file
5497 * Cleaned up the LEAVE command's channel key distribution. The
5498 affected file silcd/command.c.
5500 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
5501 can enforce the channel mode as well. In that case the ID
5502 includes the ID of the server. The code now enforces the
5503 mode change if the router have different mode than the server.
5505 * The notify client operation with CMODE_CHANGE notify can now
5506 return NULL client_entry pointer if the CMODE was not changed
5507 by client. Application must check for this.
5509 * Added <Server ID> argument to INFO command to support server
5510 info fetching by Server ID.
5512 * Added silc_server_announce_get_channel_users to get assembled
5513 packets of channel users of the specified channel. Affected
5514 file silcd/server.[ch].
5516 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
5517 was freed underneath the ID Cache.
5519 * Re-announce clients when the server received CHANNEL_CHANGE
5520 notify from the router. Affected file silcd/packet_send.c.
5522 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5524 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
5525 crashed since it did not handle the fact that there is no cipher
5526 called "3" and didn't check the error condition. Now fixed.
5528 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
5529 flag. It can be used to send message requests.
5531 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5533 * Implemented the RESTART command in the client.
5535 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
5536 notice type messages. Added notice printing to the user
5539 * The channel keys are not re-generated if the channel's mode
5540 is PRIVKEY, ie private key on the channel exists. Affected
5541 files silcd/server.c and silcd/command.c.
5543 * Fixed a little bug in channel message delivery when channel
5544 private keys are set in the server. Affected file is
5545 silcd/packet_send.c.
5547 * Changed the setting on channel->on_channel = TRUE from the
5548 silc_client_save_channel_key to the JOIN command reply. The
5549 key payload is not received if the private channel key is set.
5550 Affected file lib/silcclient/command_reply.c and the
5551 lib/silcclient/client_channel.c.
5553 * When the CMODE_CHANGE notify is sent and the channel private
5554 key mode is removed the channel key must be re-generated in
5555 other cells as well. Added this support for the router in the
5556 silcd/packet_receive.c.
5558 * Added new local command NOTICE to send notice message on
5559 channel. Affected file silc/local_command.[ch].
5561 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5563 * Added new local command ME to the client. It is used to send
5564 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
5565 some action. Affected file silc/local_command.[ch].
5567 * Changed channel_message and private_message client operations
5568 to deliver the message flags to the application. Added also
5569 the `flags' arguments to the silc_client_send_channel_message
5570 and silc_client_send_private_message functions. Affected file
5573 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5575 * Redefined the Private Message Payload to support private message
5576 keys and to support the new private message flags. Updated
5577 the protocol specs. Flags makes it possible to have for example
5578 CTCP style messages.
5580 * Added new type SilcPrivateMessagePayload and defined an API
5581 for it in the lib/silcclient/silcprivate.[ch].
5583 * Tested private message private keys successfully. Tested the
5584 private message key set, unset and list commands with the new
5587 * Redefined the Channel Message Payload to include the channel
5588 message flags (equal with private message flags) to support
5589 for example CTCP style messages.
5591 * Defined some of the message (for channel and private message)
5592 flags. Updated the protocol specs and added the flags to the
5593 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5595 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5597 * Added SilcKeyAgreementStatus type to the key agreement routines
5598 to indicate the current status and error if one occured.
5599 The status types are defined in the lib/silcclient/silcapi.h.
5601 * Added new local command KEY that is used to set and unset private
5602 keys for channels, set and unset private keys for private messages
5603 with remote clients and to send key agreement requests and
5604 negotiate the key agreement protocol with remote client. The
5605 key agreement is supported only to negotiate private message keys,
5606 it currently cannot be used to negotiate private keys for channels,
5607 as it is not convenient for that purpose.
5609 * Fixed a minor pending callback setting bug in the function
5610 silc_client_get_client_by_id_resolve, now the function works.
5611 Affected file lib/silcclient/idlist.c.
5613 * Added function silc_net_get_local_port to get local bound
5614 port by socket. Added to lib/silcutil/silcnet.[ch].
5616 * Added `sockets' and `sockets_count' fields to the SilcClient
5617 object. They hold the sockets of the listenning sockets in
5618 the client. Listenning sockets may be for example the key
5619 agreement server. Affected file lib/silcclient/client.[ch].
5620 Added functions the silc_client_add_socket and the
5621 silc_client_del_socket. They are exported to the application
5624 * Added ~./silc/clientkeys to support other client's public keys.
5626 * Renamed verify_server_key client operation to verify_public_key
5627 and added one argument to indicate the type of the connection
5628 (server, client etc.).
5630 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5632 * Added silc_server_connection_auth_request to handle the
5633 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5634 silcd/packet_receive.[ch].
5636 * Added silc_server_send_connection_auth_request into the
5637 silcd/packet_send.c to send the connection auth request packet.
5639 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5642 * Fixed the public key authentication in responder side in the
5643 server. The `auth_data' pointer includes the SilcPublicKey
5644 not the path to the public key. Affected file silcd/protocol.c.
5646 * Implemented the public key authentication in the initiator side
5647 in the server. Affected file silcd/protocol.c.
5649 * Removed the [RedirectClient] config section from the server
5650 configuration. Is not needed and I don't want to implement it.
5652 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5654 * Cleaned up the CMODE command in the server. It now works
5655 correctly and supports all the modes defined in the protocol.
5656 Affected file is silcd/command.c.
5658 * Added `hmac_name' field to the SilcChannelEntry in the server
5659 to hold the default HMAC of the channel. It can be set when
5660 creating the channel (with JOIN command). Affected files
5663 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5664 type to indicate the change of the current cipher and hmac
5665 on the channel. Client can safely ignore the <cipher> argument
5666 (if it chooses to do so) since the CHANNEL_KEY packet will
5667 force the channel key change anyway. The <hmac> argument is
5668 important since the client is responsible of setting the new
5669 HMAC and the hmac key into use.
5671 * Fixed the CMODE command in the client library as well.
5673 * Tested CMODE command in router environment successfully.
5675 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5677 * Show the version of the remote client (or server) when connecting
5678 to the server. It is logged to the log file. Affected file
5679 is silcd/protocol.c.
5681 * Fixed the KILLED notify handling in the client library. The
5682 client must be removed from all channels when receiving the
5685 Also, do not remove the client entry when giving the KILL
5686 command but when the KILLED notify is received.
5688 * Removed silc_idlist_find_client_by_nickname from the server.
5689 Not needed anymore. Affected files silcd/idlist.[ch].
5691 * Implemented the CHANNEL_CHANGE notify type handling to the
5692 server. Affected file silcd/server.c.
5696 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5698 * Added silc_server_send_notify_invite to send the INVITE
5699 notify between routers.
5701 * Implemented the INVITE command correctly to the server.
5703 * Implemented the INVITE notify type handling in the server.
5705 * Implemented the INVITE command to the client library and on the
5708 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5710 * Added function silc_server_get_client_resolve to find the
5711 client entry by ID from all ID lists and then resolve it
5712 (using WHOIS) if it cannot be found. Affected file is
5715 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5717 * Implemented the BAN command to the client library.
5719 * The JOIN command in the server now checks the invite list
5722 * Changed the silc_command_reply_payload_encode_va and the
5723 silc_command_payload_encode_va to support that if argument is
5724 NULL it ignores and checks the next argument. Affected file
5725 lib/silccore/silccommand.c.
5727 * Added silc_server_send_notify_ban to send the BAN notify
5728 type between routers.
5730 * Chaned the silc_notify_payload_encode to support that if
5731 argument is NULL it ignores and checks the next argument.
5732 Affected file lib/silccore/silcnotify.c.
5734 * Tested ban lists in router environment successfully.
5736 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5738 * Implemented BAN command to the server, in silcd/command.[ch].
5740 * Removed the BAN and INVITE_LIST modes from the CMODE command
5743 * Added function silc_string_match to regex match two strings.
5744 Affected files lib/silcutil/silcutil.[ch].
5746 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5748 * Redefined parts of the SilcChannelEntry in the server to support
5749 the new ban and invite lists.
5751 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5753 * Redefined the INVITE command. The same command can be used to
5754 invite individuals to the channel but also to manage the invite
5755 list of the channel (to add to and remove from the invite list).
5756 Updated the protocol specs.
5758 * Added new command SILC_COMMAND_BAN that can be used to manage
5759 the ban list of the channel. Updated the protocol specs.
5761 * Removed the channel modes: the SILC_CMODE_BAN and the
5762 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5763 in the CMODE command. The equivalent features are now available
5764 using INVITE and BAN commands. Updated the protocol specs.
5766 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5767 in the network about change in the current ban list. The notify
5768 type is not used by the client.
5770 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5771 support the invite lists.
5773 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5775 * Added new function silc_string_regexify that converts string
5776 including wildcard characters into regex string that can
5777 be used by the GNU regex library. Added into the file
5778 lib/silcutil/silcutil.[ch].
5780 Added silc_string_regex_combine to combine to regex strings
5781 into one so that they can be used as one regex string by
5782 the GNU regex library. Added into the file
5783 lib/silcutil/silcutil.[ch].
5785 Added silc_string_regex_match to match two strings. It returns
5786 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5788 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5790 * Imported GNU regex to the soruce tree into lib/contrib.
5791 Fixed some compiler warning from the regex.c.
5793 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5795 * Fixed MOTD command in the server to work in router environment.
5797 * Fixed the MOTD command in the client library to support
5798 the server argument in the command.
5800 * Added `nickname_len' argument to the silc_idlist_add_client
5801 in the server, as the `nickname' argument may be binary data
5804 * Added silc_idlist_get_channels to return all channels from
5807 * Implemented LIST command to the server. Affected file is
5810 * Implemented the LIST command to the client library and on the
5813 * Added [<user count>] argument to the LIST command reply.
5814 With private channels the user count is not shown.
5816 * Updated TODO and README.
5818 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5820 * The client entry's data.registered must be TRUE even with
5821 global client entry on global client list. The data.registered
5822 is used to check whether the client is anymore in the network,
5823 for example with WHOWAS command so it must be valid.
5825 * Fixed the WHOWAS command in the server. It now actually works
5826 in router environment. Added function into silcd/command_reply.c
5827 silc_server_command_reply_whowas_save.
5829 * Added silc_idlist_purge function to the silcd/idlist.c
5830 to periodically purge the ID Cache.
5832 * Fixed INFO command in the server. It works now in router
5833 environment. Added <server name> argument to the INFO command
5834 reply. Updated the protocol specs.
5836 * Fixed minor bug in silc_idcache_purge to not purge if the
5837 expire value is zero.
5839 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5840 they were buggy because of the WHOWAS information.
5842 * Fixed local command MSG to handle the async resolving of
5843 the remote client properly. It used to fail the first MSG.
5844 Affected file silc/local_command.c.
5846 * Added `data_len' field to SilcIDCache context.
5848 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5850 * Update TODO. Todo in commands in the server.
5852 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5854 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5855 used by routers as broadcast packet to inform other routers
5856 about the changed user mode.
5858 Implemented the notify handling in the server. Affected file is
5859 silcd/packet_receive.c. Added the function
5860 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5862 * Added new generic Channel Payload and deprecated the New Channel
5863 Payload. The New Channel Payload is now the generic Channel
5866 * Added new argument `mode' to the silc_server_send_new_channel
5867 as it is required in the Channel Payload now.
5869 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5870 and created a new and real SilChannelPayload to represent the
5871 new generic Channel Payload. Implemented the encode/decode
5872 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5874 * Added silc_server_get_client_channel_list to return the list
5875 of channels the client has joined for WHOIS command reply.
5876 Affected file silcd/server.[ch].
5878 * Implemented the channel list sending in the WHOIS command reply
5879 in server and in the client.
5881 Implemented the channel list displaying on the user interface
5882 as well. Affected file silc/client_ops.c.
5884 * Added silc_channel_payload_parse_list to parse list of Channel
5885 Payloads. It returns SilcDList list of SilcChannelPayloads.
5886 Client for example can use this function to parse the list of
5887 channels it receives in the WHOIS command reply. The caller
5888 must free the list by calling silc_channel_payload_list_free.
5889 Affected files lib/silccore/silcchannel.[ch].
5891 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5893 * Added one new argument <user mode> to the WHOIS command reply
5894 to return the mode of the user in SILC. Updated the protocol
5897 Implemented it to the server and client.
5899 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5901 * Fixed the mode printing on the user interface on joining.
5902 Affected file silc/client_ops.c.
5904 * Implemented the UMODE command and user modes in general to the
5905 client library and to the user interface.
5907 * Implemented the UMODE command to the server.
5909 * The server now sends UNKNOWN_COMMAND error status if client sends
5910 unknown command. Affected file silcd/command.c.
5912 * All server commands now handle the command identifier the right
5913 way when sending the command reply to the client. The client can
5914 use to identify the command replies with the identifier.
5916 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5918 * Added silc_server_get_client_route to resolve the route to
5919 the client indicated by the client ID. Affected file is
5922 * Added silc_server_relay_packet as general function to relay
5923 packet to arbitrary destination. This deprecates functions
5924 like _send_private_message_key, _relay_notify etc. Affected
5925 file is silcd/packet_send.[ch].
5927 Removed silc_server_send_key_agreement,
5928 silc_server_send_private_message_key and
5929 silc_server_packet_relay_notify functions from the file
5930 silcd/packet_send.[ch].
5934 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5935 server. Affected file silcd/packet_receive.[ch].
5937 * Implemented the KILL command to the client. Implemented the
5938 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5939 Affected files lib/silcclient/command[_reply].c and
5940 lib/silcclient/client_notify.c. Implemented the KILL notify
5941 printing in the user inteface.
5943 * Fixed a lot silc_parse_nick memory leaks from the client
5944 library in the file lib/silcclient/command.c.
5946 * Changed the silc_server_send_notify_on_channels's `sender'
5947 argument from SilcSocketConnection to SilcClientEntry to
5948 check the sender as entry and not as connection object and not
5949 to send to the client provided as argument. The affected file
5950 is silcd/packet_send.[ch].
5952 * The notify packets that are destined directly to the client used
5953 to not to be processed by the server. Now changed that and the
5954 server processes all notify packets. After relaying the packet
5955 to the client the notify packet is processed in the server.
5957 * The silc_server_free_client_data now checks whether there is
5958 pending outgoing traffic for the client and purges the data to
5959 the network before removing the client entry.
5961 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5963 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5964 an client is killed from the SILC Network. Updated the protocol
5967 Added new function silc_server_send_notify_killed to the
5968 silcd/packet_send.[ch].
5970 * Added function silc_server_packet_relay_notify to relay notify
5971 packets that are destined directly to a client. In this case
5972 the server does not process the notify packets but merely relays
5973 it to the client. Affected file silcd/packet_send.[ch].
5975 Added also silc_server_packet_process_relay_notify to check
5976 whereto relay the notify. Affected file is
5977 silcd/packet_receive.[ch].
5979 * Implemented the KILL command to the server.
5983 * Added the backup schema desgined last fall to the protocol
5984 specs for everyone to see. The specification is in the
5985 *-spec-xx.txt draft and the packet type definitions for the
5986 backup routers is in *-pp-xx.txt draft. Thusly, added also
5987 new packet type SILC_PACKET_CELL_ROUTERS.
5989 * A big security problem in the implementation discovered. The
5990 signoff of an client did not cause new channel key generation
5991 which it of course should've done. The channel keys must be
5992 always re-generated when client leaves (or signoffs) the channel.
5993 The silc_server_remove_from_channels funtion now handles
5994 the channel key re-generation.
5996 * Added `sender' argument to the silc_server_send_notify_on_channels
5997 to not to send the client provided as argument. Affected file
5998 silcd/packet_send.[ch].
6000 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6002 * Implemented OPER and SILCOPER commands into the server and
6005 * Added silc_auth_verify and silc_auth_verify_data to verify
6006 the authentication directly from the authentication payload.
6007 It supports verifying both passphrase and public key based
6008 authentication. Affected file lib/silccore/silcauth.[ch].
6010 * Added `hash' field to the SilcIDListData structure. It is the
6011 hash negotiated in the SKE protocol. Affected file is
6014 * Slight redesigning of the SilcAuthPayload handling routines.
6015 Do not send SilcPKCS but SilcPublicKey as argument.
6017 * Implemented the public key authentication support to the
6018 serverconfig. The public key is loaded from the provided path
6019 and saved as authentication data to void * pointer. Thus,
6020 changed the unsigned char *auth_data to void *auth_data;
6022 * Fixed SHUTDOWN command to send the reply before the server
6023 is shutdown. :) Affected file silcd/command.c.
6025 * Fixed fatal bug in CONNECT command. The hostname was invalid
6026 memory and server crashed. Affected file silcd/command.c.
6028 * Fixed fatal bug in CLOSE command. The server_entry became
6029 invalid but was referenced later in the command. Affected file
6032 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6034 * Fixed fatal bug in failure packet handling. Server ignored
6035 the failure and thus crashed when it came.
6039 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6041 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
6042 that the command may be executed only once in (about) 2 seconds.
6043 The old SILC_CF_LAG flag is same but allows command bursts up
6044 to five before limiting.
6046 Added the support for CF_LAG and CF_LAG_STRICT flags to the
6047 server code. Various commands now includes the CF_LAG_STRICT
6048 flag to disallow any kind of miss-use of the command.
6050 * Fixed the silc_buffer_unformat to not to allocate any data
6051 if the length of the data is zero. It used to allocate the
6052 length + 1. Affected file lib/silcutil/silcbuffmt.c.
6054 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6056 * Changed the format of AdminConnection configuration section
6057 in the server. Added username of the admin to the format.
6058 Affected files silcd/serverconfig.[ch].
6060 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
6061 to return admin configuration data by host, username and/or
6064 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6066 * Implemented WHOWAS command to the server. Added the functions:
6068 silc_server_command_whowas_parse,
6069 silc_server_command_whowas_send_reply,
6070 silc_server_command_whowas_from_client and
6071 silc_server_command_whowas_from_server
6073 * Added <Client ID> argument to the WHOWAS command reply. Updated
6074 the protocol specs accordingly.
6076 * Implemented WHOWAS command and command_reply to the client
6079 Implemented the WHOWAS printing on the user interface.
6081 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6083 * Added new argument to the WHOWAS command reply, the real name.
6084 It is an optional argument. Updated the protocol specs.
6086 * Added SilcIDCacheDestructor callback that is registered when
6087 the SilcIDCache is allocated. The callback is called when
6088 an cache entry in the ID Cache expires, or is purged from the
6089 cache. Added into lib/silccore/idcache.[ch].
6091 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
6092 to destruct the client entries when the cache entry expires.
6093 Other ID Cache's in server and in the client library ignores
6096 * If the ID Cache entry's `expire' field is zero then the entry
6097 never expires. Added boolean `expire' argument to the
6098 silc_idcache_add function in the lib/silccore/idcache.[ch].
6099 If it is TRUE the default expiry value is used.
6101 * Added silc_server_free_client_data_timeout that is registered
6102 when client disconnects. By default for 5 minutes we preserve
6103 the client entry for history - for WHOWAS command.
6105 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6107 * Added support to the server to enforce that commands are not
6108 executed more than once in 2 seconds. If server receives
6109 commands from client more frequently, timeout is registered
6110 to process the commands. Affected file silcd/command.c.
6111 Added new function silc_server_command_process_timeout.
6113 * Changed NICK_NOTIFY handling in client library to check that
6114 if the client's nickname was changed, so there is no need to
6115 resolve anything from the server.
6117 * Removed error printing from the WHOIS and IDENTIFY commands.
6118 If error occurs then it is ignored silently in the client library.
6119 The application, however, may map the received error to
6120 human readable error string. The application currently maps
6121 the NO_SUCH_NICKNAME error to string.
6123 * Made the command status message public to the application. Moved
6124 them from lib/silcclient/command_reply.c to
6125 lib/silcclient/command_reply.h. The application can map the
6126 received command status to the string with the
6127 silc_client_command_status_message function.
6129 * Added check to the server to check that client's ID is same
6130 as the Source ID in the packet the client sent. They must
6133 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6135 * Added dist-bzip hook to the Makefile.am to make bzip2
6136 compressed distributions.
6138 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6140 * Server now enforces the maximum length for the nickname and
6141 the channel as protocol specification dictates. 128 bytes for
6142 nickname and 256 bytes for channel name.
6144 * Moved the WHOIS printing to the application. The client libary
6145 does not print out the WHOIS information anymore, the application
6146 must do it. Renamed silc_client_command_reply_whois_print to
6147 the silc_client_command_reply_whois_save.
6149 The client's idle time is also sent to the application now, and
6150 the idle is shown on screen.
6152 * Added silc_client_command_reply_identify_save to save the
6153 received IDENTIFY entries.
6155 * Do not check for channel private keys in message sending and
6156 reception if the channel does not have the PRIVKEY mode set.
6157 Affected file lib/silclient/client_channel.c.
6159 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6161 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
6162 just surfaced after chaning the JOIN procedure.
6164 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6166 * Added silc_client_get_clients_by_list to get client entries
6167 from Client ID list, that is returned for example by JOIN
6168 and USERS command replies. The application should use this
6169 function for example when JOIN command reply is received to
6170 resolve the clients already on the channel (library does not
6171 do that anymore as USERS command reply is not used in the JOIN
6172 procedure anymore). Affected files lib/silcclient/silcapi.h and
6173 lib/silcclient/idlist.c.
6175 * JOIN command reply and USERS command reply returns now SilcBuffer
6176 pointers instead of unsigned char pointers when returning
6177 the client list and mode list.
6179 * Added <Client ID> argument to the JOIN command reply, mainly
6180 for the server to identify for which client the command was
6181 originally sent. Updated protocol specs accordingly.
6183 * Added SilcDlist private_key pointer to the SilcChannelEntry
6184 in the client to support the channel private keys. Affected
6185 file is lib/silcclient/idlist.h.
6187 * Added SilcChannelPrivateKey argument to the function
6188 silc_client_send_channel_message so that application can choose
6189 to use specific private ke if it wants to. If it is not provided,
6190 the normal channel key is used, unless private keys are set.
6191 In this case the first (key that was added first) is used
6192 as the encryption key.
6194 * Implemented the support for channel private key handling.
6195 Implemented the following functions:
6197 silc_client_add_channel_private_key,
6198 silc_client_del_channel_private_keys,
6199 silc_client_del_channel_private_key,
6200 silc_client_list_channel_private_keys and
6201 silc_client_free_channel_private_keys
6203 Affected file lib/silcclient/client_channel.c.
6205 * Added the support for the private keys in the channel message
6206 sending and encryption and in the message reception and
6207 decryption. Affected funtions are
6208 silc_client_send_channel_message and silc_client_channel_message.
6210 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6212 * Added SKE's key verify callback to the client library's
6213 KE protocol context. Affected files lib/silcclient/protocol.[ch].
6215 * Removed the statement that server (or router) must send USERS
6216 command reply when joining to the channel so that the client
6217 knows who are on the channel. Instead, the client list and
6218 client's mode list is now sent in the JOIN command reply to the
6219 client who joined channel. This is better solution.
6221 * Added function silc_server_get_users_on_channel and function
6222 silc_server_save_users_on_channel to the silcd/server.[ch].
6224 * Removed function silc_server_command_send_users from the
6227 * Do not show topic on the client library anymore. The topic is
6228 sent in the command reply notify to the application and the
6229 application must show the topic now.
6231 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6233 * Added client searching by nickname hash into the IDENTIFY and
6234 WHOIS commands in the server as they were clearly missing from
6235 them. Affected file is silcd/command.c.
6237 * Fixed a bug in private message receiving in the client library.
6238 The remote ID was freed and it wasn't supposed, now it is
6241 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6243 * Minor fix to the channel payload; allocate the data area, as it
6244 needs to be of specific length.
6246 * If the key agreement port is zero then the operating
6247 system will define the bound port. Affected files are
6248 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
6250 * Added new function silc_channel_payload_decrypt into the file
6251 lib/silccore/silcchannel.[ch].
6253 * Moved the channel message etc, check from silc_packet_decrypt
6254 to applications. The library calls now a generic
6255 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
6256 when the packet is either normal or special. This was done to
6257 allow more wide range of checking that was not allowed when
6258 the code was in library. Now applications can do virtually any
6259 checks to the packet and return to the library the decision how
6260 the packet should be processed. Affected files are
6261 lib/silccore/silcpacket.[ch].
6263 Added silc_server_packet_decrypt_check to the server and
6264 silc_client_packet_decrypt_check to the client library.
6266 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
6267 to send with specified source and destination information.
6269 * Channel message delivery between routers was broken after the
6270 channel key distribution was fixed earlier. The channel key
6271 was used be to distributed to other routers as well which is not
6272 allowed by the protocol. Now this is fixed and channel keys
6273 really are cell specific and the channel message delivery between
6274 routers comply with the protocol specification.
6276 * Fixed various commands in server to check also the global list
6277 for the channel entry and not just the local list. The affected
6278 file silcd/command.c.
6280 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6282 * Added assert()s to buffer formatting and unformatting routines
6283 to assert (if --enable-debug) when error occurs. Affected
6284 file: lib/silcutil/silcbuffmt.c.
6286 * Changed to auto-reconnect to check whether the remote host is
6287 router and register the re-connect timeout if it is. It used
6288 to check that whether we are normal server, but router must do
6289 auto-reconnect with another router as well. Affected file
6292 * Removed the [<key len>] option from CMODE command as the cipher
6293 name decides the key length, nowadays. See the defined ciphers
6294 from the protocol specification.
6296 * Added [<hmac>] option to the CMODE command to define the HMAC
6297 for the channel. Added SILC_CMODE_HMAC channel mode.
6299 * Added [<hmac>] option for the JOIN command so that user can
6300 select which HMAC is used to compute the MACs of the channel
6303 * Added Hmac field to the Channel Message Payload. The integrity
6304 of plaintext channel messages are now protected by computing
6305 MAC of the message and attaching the MAC to the payload. The
6306 MAC is encrypted. Now, it is clear that this causes some
6307 overhead to the size of the packet but rationale for this is that
6308 now the receiver can verify whether the channel message decrypted
6309 correctly and also when private keys are set for the channel the
6310 receiver can decrypt the packet with several keys and check from
6311 the MAC which key decrypted the message correctly.
6313 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
6314 lib/silccrypt/silccipher.[ch].
6316 * Added silc_hash_len to return the digest length into the
6317 lib/silcrypt/silchash.[ch].
6319 * Rewrote parts of Silc Channel Payload interface in the
6320 lib/silccore/silcchannel.[ch]. The encode function now also
6321 encrypts the packet and parse function decrypts it.
6323 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6325 * Fixed a minor formatting bug in the SKE's key material processing.
6326 It actually might have processed the keys wrong way resulting
6329 * Redefined the mandatory HMAC algorithms and added new algorithms.
6330 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
6331 and hmac-md5 truncated to 96 bits. The mandatory is now
6332 hmac-sha1-96. Rest are optional (including the one that used
6333 to be mandatory). Rationale for this is that the truncated HMAC
6334 length is sufficient from security point of view and can actually
6335 make the attack against the HMAC harder. Also, the truncated
6336 HMAC causes less overhead to the packets. See the RFC2104 for
6339 * Added new [hmac] configuration section. The SKE used to use
6340 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
6341 is of course wrong. The official names that must be proposed in
6342 the SKE are the ones defined in the protocol specification
6343 (hmac-sha1-96 for example). The user can configure any hmac
6344 using any hash function configured in the [hash] section. At
6345 least, the mandatory must be configured.
6347 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
6349 * Added HMAC list to the SKE proposal list. It has now both
6350 hash algorithm list and HMAC list. This makes the protocol
6351 incompatible with previous versions. The SKE now seems to work
6352 the way it is supposed to work, for the first time actually.
6354 * Defined plain Hash algorithms to the protocol specification.
6357 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6359 * Implemented support for key agreement packets into the server.
6360 Added functions silc_server_key_agreement and
6361 silc_server_send_key_agreement. Other than these functions,
6362 server has nothing to do with this packet.
6364 * Added support for private message key packets into the server.
6365 Added functions silc_server_private_message_key and
6366 silc_server_send_private_message_key.
6370 * Changed the silc_[client|server]_protocol_ke_set_keys to be
6371 called in the protocol's final callback instead in the END
6372 protocol state. This makes a little more sense and in the same
6373 time in client we can use the same protocol routines for normal
6374 key exchange and to key agreement packet handling as well.
6376 * Added to both client's and server's KE protocol context the
6377 SilcSKEKeyMaterial pointer to save the key material. We will
6378 bring the key material to the protocol's final callback by doing
6379 this. The final callback must free the key material.
6381 * Added SKE's packet_send callback into client's KE protocol
6382 context so that the caller can choose what packet sending function
6383 is used. This way we can use different packet sending when
6384 doing normal SKE when doing key agreement packet handling (in
6385 the key agreement packet handling we do not want to encrypt
6388 * Implemented the responder side of the key agreement routines
6389 in the client. The client can now bind to specified port and
6390 accept incoming key negotiation. The key material is passed
6391 to the application after the protocol is over.
6393 * Implemented the processing of incoming Key Agreement packet
6394 in the client. Added function silc_client_key_agreement to
6397 * Implemented the intiator side of the key agreement routines
6398 in the client. The client can now initiate key agreement with
6399 another remote client. The key material is passed to the
6400 application after the protocol is over.
6402 * Created client_keyagr.c to include all the key agreement
6405 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
6406 SILC_TASK_CALLBACK except that it is not static.
6408 * Created client_notify.c and moved the Notify packet handling
6409 from the client.[ch] into that file.
6411 * Created client_prvmsg.c and moved all private message and
6412 private message key routines from the client.[ch] into that file.
6414 * Create client_channel.c and moved all channel message and
6415 channel private key routines from the client.[ch] into that file.
6417 * Changed silc_client_get_client_by_id_resolve to resolve with
6418 WHOIS command instead of IDENTIFY command, in the file
6419 lib/silclient/idlist.c.
6421 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6423 * Implemented the SKE's responder side to the Client library.
6425 * When FAILURE is received to the protocol do not trust it
6426 blindly. Register a timeout to wait whether the remote closes
6427 the connection as it should do it, only after that process the
6428 actual failure. This was changed to both client and server.
6430 * Added client_internal.h to include some of the structures
6431 there instead of client.h in lib/silcclient/.
6433 * Added function silc_task_unregister_by_callback to unregister
6434 timeouts by the callback function.
6436 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6438 * Some "Incomplete WHOIS info" errors has been appearing on the
6439 log files. Took away the entry->userinfo check from WHOIS
6440 reply sending. The entry->userinfo is now " " if client did not
6441 provide one. I thought this was fixed earlier but something
6442 is wrong still. Let's see if the error still appears.
6444 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6446 * Fixed a minor bug in the login when the channel key is
6447 re-generated in the server. It used to generate the key in
6448 wrong order and thus caused problems in the channel traffic.
6450 * Fixed a minor bug in channel key distsribution after
6451 KICK command. The key was not sent to the router even though
6454 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6456 * Added silc_ske_process_key_material_data as generic routine
6457 to process any key material as the SILC protocol dictates. The
6458 function is used by the actual SKE library but can be used by
6459 applications as well. This relates to the private message keys
6460 and the channel private keys since they must be processed the
6461 same way the normal SILC session keys. The protocol dictates
6462 this. Affected files: lib/silcske/silcske.[ch].
6464 Added also silc_ske_free_key_material to free the
6465 SilcSKEKeyMaterial structure.
6467 * Defined silc_cipher_set_key function to set the key for
6468 cipher without using the object's method function. The affected
6469 files: lib/silccrypt/silccipher.[ch].
6471 * Implemented silc silc_client_add_private_message_key,
6472 silc_client_add_private_message_key_ske,
6473 silc_client_del_private_message_key,
6474 silc_client_list_private_message_keys and
6475 silc_client_free_private_message_keys functions in the
6478 Added functions silc_client_send_private_message_key to send
6479 the Private Message Key payload and silc_client_private_message_key
6480 to handle incoming Private Message Key payload.
6482 * Added Cipher field to the Private Message Key payload to set
6483 the cipher to be used. If ignored, the default cipher defined
6484 in the SILC protocol (aes-256-cbc) is used.
6486 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6488 * Removed lib/silcclient/ops.h file.
6490 Redefined parts of the SILC Client Library API. Created new
6491 file silcapi.h that deprecates the ops.h file and defines the
6492 published Client Library API. Defined also private message key
6493 API and channel private key API into the file.
6495 This is the file that the application must include from the
6496 SILC Client Library. Other files need not be included by
6497 the application anymore.
6499 * Added new key_agreement client operation callback and also
6500 defined the Key Agreement library API for the application.
6502 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6504 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
6505 is used by clients to request key negotiation between another
6506 client in the SILC network. If the negotiation is started it
6507 is performed using the SKE protocol. The result of the
6508 negotiation, the secret key material, can be used for example
6509 as private message key.
6511 Implemented the Key Agreement payload into the files
6512 lib/silccore/silauth.[ch].
6514 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6516 * Redefined ciphers for the SILC protocol. Added some new ciphers
6517 and defined the key lengths for the algorithms. Changed the
6518 code accordingly. The default key length is now 256 bits.
6520 * Fixed SKE key distribution function silc_ske_process_key_material
6521 when the key length is more than 128 bits. The default key
6522 length in SILC is now 256 bits.
6524 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
6525 to indicate unsupported algorithm.
6527 * Renamed rijndael.c to aes.c and all functions as well.
6529 * Fixed a long standing channel key setting bug in client library.
6530 Weird that it has never surfaced before.
6532 * Fixed bug in channel deletion. If the entire channel is removed
6533 then it must also delete the references of the channel entry
6534 from the client's channel list as the client's channel entry and
6535 the channel's client entry share same memory.
6537 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6539 * Implemented CONNECT and SHUTDOWN commands in the client.
6541 * Implemented CLOSE command to the client.
6543 * Added the function silc_idlist_find_server_by_name into the
6544 files silcd/idlist.[ch].
6546 Added the function silc_idlist_find_server_by_conn into the
6547 files silcd/idlist.[ch].
6549 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6551 * DIE command was renamed to SHUTDOWN. Updated the both code
6554 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
6555 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
6557 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
6560 * Added function silc_server_create_connection function to create
6561 connection to remote router. My server implementation actually
6562 does not allow router to connect to normal server (it expects
6563 that normal server always initiates the connection to the router)
6564 so the CONNECT command is only good for connecting to another
6567 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6569 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
6570 or some other client was kicked from the channel.
6572 Implemented the handling of the notify type to both client
6575 Implemented silc_server_send_notify_kicked to send the KICKED
6576 notify. It is used to send it to the server's primary router.
6578 * Implemented the KICK command into server and client.
6580 * Added `query' argument to the silc_idlist_get_client function
6581 to indicate whether to query the client from server or not if
6584 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
6585 to indicate that the client is not channel founder.
6589 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6591 * Removed the rng context from SilcPacketContext structure and
6592 changed that the packet routine uses the Global RNG API.
6594 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6596 * Added support for quit message that client can "leave" on the
6597 channel when it quits the SILC. It is ditributed inside the
6598 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6600 Added silc_server_free_client_data that will take the
6601 signoff message as argument.
6603 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6605 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6607 * Updated parts of the protocol specification to keep it up
6610 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6612 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6613 payloads in one packet.
6615 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6616 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6617 use now the new List flag.
6619 * Also deprecated the following packet types: REPLACE_ID,
6620 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6622 * Added list support for Notify packet in server.
6624 * Added silc_server_send_notify_channel_change to send the
6625 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6626 the silc_server_send_replace_id.
6628 * Added silc_server_send_notify_nick_change to send the
6629 NICK_CHANGE notify type. Deprecates the function
6630 silc_server_send_replace_id.
6632 * Added silc_server_send_notify_join to send the JOIN notify type.
6633 Deprecates the function silc_server_send_new_channel_user.
6635 * Added silc_server_send_notify_leave to send LEAVE notify type.
6636 Deprecates the function silc_server_send_remove_channel_user.
6638 * Added silc_server_send_notify_cmode and
6639 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6640 types. Deprecates the silc_server_send_set_mode function.
6642 * Added SERVER_SIGNOFF notify type to indicate that server has
6643 quit. This means that all clients on the channel from that
6644 server will drop. This can be also used when netsplit happens.
6646 Deprecated REMOVE_ID packet type since it is not needed anymore
6649 Added silc_server_send_notify_server_signoff to send the
6650 SERVER_SIGNOFF notify type. Deprecates the function
6651 silc_server_send_remove_id.
6653 Added also silc_server_send_notify_signoff to send the
6654 SIGNOFF notify type.
6656 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6657 SILC protocol from this day on. Changed the protocol
6658 specification as well.
6660 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6661 notify type. It is used between routers to notify about
6662 topic changes on a channel.
6664 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6667 * Partly updated the protocol specification to comply with the
6668 changes now made. It is still though a bit outdated.
6670 * The JOIN notify type now takes one extra argument <Channel ID>.
6671 The packet used to be destined to the channel but now the
6672 JOIN type may be sent as list thus it is impossible to
6673 destine it to any specific channel. By adding this argument
6674 it is again possible.
6676 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6678 * Added CREDITS file. The CHANGES and CREDITS file will appear
6679 in the distribution as well.
6681 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6683 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6684 types in the server's silcd/packet_receive.c.
6686 * Implemented CMODE and CUMODE to work in router environment.
6688 * Fixed minor encoding and decoding buglet from the
6689 lib/silccore/silcmode.c.
6691 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6694 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6696 * Changed all SilcConfigServer* and silc_config_server* to
6697 SilcServerConfig* and silc_server_config*, respectively.
6700 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6702 * Associated the ID (client or server ID) to the Authentication
6703 Payload to avoid any possibility of forging. Updated the
6704 protocol specification and the code accordingly.
6706 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6708 * The RSA key length is now save to the RsaKey context in the
6709 key generation process in lib/silccrypt/rsa.c. The key length
6710 is now used to figure out the maximum size of the block allowed
6711 to be encrypted/signed.
6713 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6714 is equivalent to the silc_mp_mp2bin but does not allocate any
6717 * Changed silc_mp_mp2bin API to take length argument. If it is
6718 non-zero then the buffer is allocated that large. If zero, then
6719 the size is approximated using silc_mp_sizeinbase, which however
6722 * Created Global RNG API which is global RNG that application can
6723 initialize. After initializing, any routine anywhere in the
6724 code (including library) can use RNG without allocating a new
6725 RNG object. This was done to allow this sort of use of the
6726 RNG in code that has no chance to allocate RNG object. All
6727 applications currently allocate this and many routines in the
6728 library use this. Affected file lib/silccrypt/silcrng.[ch].
6730 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6731 it to use the Global RNG API.
6733 * Defined Authentication Payload into protocol specification that
6734 is used during SILC session to authenticate entities. It is
6735 used for example by client to authenticate itself to the server
6736 to obtain server operator privileges.
6738 Implemented this payload into the lib/silccore/silcauth.[ch].
6739 Implemented also routines for public key based authentication
6740 as the new protocol specification dictates.
6742 Moved definitions of different authentication methods from
6743 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6745 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6746 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6747 silc_pkcs_verify_with_hash functions into the file
6748 lib/silccrypt/silcpkcs.[ch].
6750 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6752 * The client entry's userinfo pointer must be always valid.
6753 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6754 will fail since it requires the userinfo. Now, the userinfo
6755 is allocated as "" if actual userinfo does not exist. Actually,
6756 it must exist and it is totally Ok to drop client connections
6757 that does not announce the userinfo. However, we will make
6758 this workaround for now.
6760 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6761 to return the remote port by socket.
6763 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6765 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6766 SILC_SERVER_PENDING_EXEC and added an new macro
6767 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6768 data or when error occurs while processing the pending command.
6770 Added new argument `destructor' into silc_server_command_pending
6771 and to the SilcServerCommandPending object. This destructor is
6772 now called after calling the pending callback or if error occurs
6773 immediately. If error occurs the actual pending callback won't
6774 be called at all - only the destructor. The destructor may be
6775 NULL if destructor is not needed.
6777 All this applies for client library code as well. Similar
6778 changes were made there as well for the pending commands.
6780 In the client, the application must now allocate the
6781 SilcClientCommandContext with the silc_client_command_alloc
6784 * Added reference counter to the SilcServerCommandContext. Added
6785 function silc_server_command_alloc and silc_server_command_dup
6788 Same type of functions added to the client library for the same
6791 * Removed the cmd_ident from IDListData away since it is now
6792 global for all connections. It is the command identifier used
6793 in command sending and with pending commands. The affected file
6796 * Added reference counter to the SilcSocketConnection objecet to
6797 indicate the usage count of the object. The object won't be
6798 freed untill the reference counter hits zero. Currently only
6799 server uses this, and client ignores it. The client must be
6800 set to use this too later. The affected files are
6801 lib/silccore/silcsockconn.[ch]. Added also the function
6802 silc_socket_dup to increase the reference counter.
6804 This was mainly added because it is possible that the socket
6805 is removed underneath of pending command or other async
6806 operation. Now it won't be free'd and proper DISCONNECTING
6807 flags, etc. can be set to avoid sending data to connection that
6808 is not valid anymore.
6810 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6811 the connection. After that it sets SILC_SET_DISCONNECTED.
6812 It is, however, possible that the socket data is not still freed.
6813 The silc_server_packet_process now checks that data is not
6814 read or written to connection that is DISCONNECTED. The socket
6815 get's freed when the reference counter hits zero.
6817 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6819 * Changed the client operation API: channel_message operation's
6820 `sender' is now the client entry of the sender, not the nickname
6821 and the `channel' is the channel entry, not the channel name.
6823 In the private_message operation the `sender' is now also the
6824 client entry of the sender not the nickname.
6826 Affected file is lib/silcclient/ops.h and all applications
6827 using the client operations.
6829 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6831 * Moved the calling of ops->connect() from connect_to_server_final
6832 into receive_new_id functin since that is the point when the
6833 client is actually allowed to send traffic to network. The
6834 affected file is lib/silcclient/client.c.
6836 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6838 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6839 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6840 (if needs broadcasting) instead of broadcasting the packets one
6841 by one which would make a burst in the network traffic.
6843 * Added `broadcast' argument to the functions in silcd/server.[ch]
6844 silc_server_create_new_channel[_with_id] to indicate whether
6845 to send New Channel packet to primary router.
6847 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6849 * Added new function into the silcd/server.[ch] files:
6850 silc_server_create_new_channel_with_id to create new channel with
6851 already existing Channel ID.
6853 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6854 lib/silccore/silcpacket.h. This packet is used t send list of
6855 Set Mode payloads inside one packet. Server uses this to set
6856 the modes for the channels and clients on those channels, that it
6857 announced to the router when it connected to it. The protocol
6858 specification has been updated accordingly.
6860 * The silc_server_new_channel did not handle the packet coming
6861 from normal server as it normally does not send that. However,
6862 when it announces its channels it does send it. Implemented
6863 the support for that.
6865 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6866 into the file lib/silccore/id.h.
6868 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6870 * Fixed memory leaks in the functions silc_idlist_del_client,
6871 silc_idlist_del_channel and silc_idlist_del_server in the file
6872 silcd/idlist.c. All of those leaked like a sieve.
6874 * Fixed some small memory leaks in the client's function
6875 silc_client_notify_by_server.
6877 * Added functions into silcd/server.c: silc_server_announce_clients,
6878 silc_server_announce_channels and silc_server_announce_server.
6879 These functions are used by normal and router server to announce
6880 to its primary router about clients, channels and servers (when
6881 router) that we own. This is done after we've connected to the
6884 These functions effectively implements the following packet types:
6885 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6886 and SILC_PACKET_NEW_ID_LIST.
6888 * Added new functions into the silcd/packet_receive.[ch]:
6889 silc_server_new_id_list, silc_server_new_channel_list and
6890 silc_server_new_channel_user_list to handle the incoming
6891 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6893 * Added support of changing Channel ID in the function
6894 silc_server_replace_id. If the server that announces a channel
6895 to the router already exists in the router (with same name but
6896 with different Channel ID), router is responsible to send
6897 Replace ID packet to the server and force the server to change
6898 the Channel ID to the one router has.
6900 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6901 client that the Channel ID has been changed by the router. The
6902 normal server sends this to the client. Client must start using
6903 the new Channel ID as the channel's ID.
6905 Implemented handling of this new type into lib/silcclient/client.c
6906 into the function silc_client_notify_by_server.
6908 * Added new function silc_idlist_replace_channel_id into the files
6909 silcd/idlist.[ch] to replace the Channel ID.
6911 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6913 * Call silc_server_command_identify_check always when processing
6914 the IDENTIFY command in silcd/command.c
6916 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6918 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6919 send keepalive packets. The packet can be sent by clients,
6920 servers and routers.
6922 Added function silc_socket_set_heartbeat into the file
6923 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6924 If not set, the heartbeat is not performed. The actual
6925 heartbeat is implemented in the low level socket connection
6926 library. However, application is responsible of actually
6929 Added silc_server_send_heartbeat to send the actual heartbeat
6930 packet into silcd/packet_send.[ch]. Server now performs
6931 keepalive with all connections.
6933 * Added silc_task_get_first function into lib/silcutil/silctask.c
6934 to return the timeout task with shortest timeout. There was a bug
6935 in task unregistration that caused problems. TODO has been
6936 updated to include that task system must be rewritten.
6938 * The client library will now resolve the client information when
6939 receiving JOIN notify from server for client that we know but
6940 have incomplete information.
6942 * Rewrote parts of silc_server_remove_from_channels and
6943 silc_server_remove_from_one_channel as they did not remove the
6944 channel in some circumstances even though they should've.
6946 * Encryption problem encountered in server:
6948 The LEAVE command used to send the Channel Key packet to the
6949 router immediately after generating it. However, the code
6950 had earlier sent Remove Channel user packet but not immediately,
6951 ie. it was put to queue. The order of packets in the router
6952 was that Channel Key packet was first and Remove Channel User
6953 packet was second, even though they were encrypted in the
6954 reverse order. For this reason, MAC check failed. Now, this
6955 is fixed by not sending the Channel Key packet immediately but
6956 putting it to queue. However, this is more fundamental problem:
6957 packets that are in queue should actually not be encrypted
6958 because packets that are sent immediately gets encrypted
6959 actually with wrong IV (and thus MAC check fails). So, packets
6960 that are in queue should be encrypted when they are sent to
6961 the wire and not when they put to the queue.
6963 However, the problem is that the current system has not been
6964 designed to work that way. Instead, the packet is encrypted
6965 as soon as possible and left to the queue. The queue is then
6966 just purged into wire. There won't be any fixes for this
6967 any time soon. So, the current semantic for packet sending
6970 o If you send packet to remote host and do not force the send
6971 (the packet will be in queue) then all subsequent packets to the
6972 same remote host must also be put to the queue. Only after the
6973 queue has been purged is it safe again to force the packet
6976 o If you send all packets immediately then it safe to send
6977 any of subsequent packets through the queue, however, after
6978 the first packet is put to queue then any subsequent packets
6979 must also be put to the queue.
6981 Follow these rules and everything works fine.
6983 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6985 * Added new function silc_server_remove_clients_by_server to
6986 remove all client entries from ID list when the server connection
6987 is lost. In this case it is also important to invalidate all
6988 client entires as they hold the invalid server entry. This
6989 fixes fatal bug when server has lost connection and will reconnect
6992 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6994 * Made some sanity checks to silc_server_daemonise like to check
6995 whether the requested user and group actually exists.
6997 * Added sanity check to SKE's silc_ske_responder_finish to check
6998 that the public and private key actually is valid.
7000 * Invalidate the client's nickname when receiving Replace ID
7001 packet and the Client ID is being replaced. This means that the
7002 server will query the nickname if someone needs it (client)
7005 * Sort the ID Cache in client library when the ID Cache data
7006 has changed (needs sorting).
7008 * Do not allow for SILC client to create several connections to
7009 several servers. The client does not support windows right now
7010 and generating multiple connections causes weird behaviour.
7012 Irssi-silc client does support windows and can handle several
7013 connections without problems, see: www.irssi.org and SILC plugin.
7015 * Fixed some places where client was added to the IDList. The
7016 rule of thumb is following (in order to get everything right):
7017 If the client is directly connected local client then the
7018 `connection' argument must be set and `router' argument must be
7019 NULL to silc_idlist_add_client function. If the client is not
7020 directly connected client then the `router' argument must
7021 bet set and the `connection' argument must be NULL to the
7022 silc_idlist_add_client function.
7024 * The funtion silc_server_packet_send_local_channel actually did
7025 not check whether the client was locally connected or not. It
7026 does that now. Fixed a bug related to LEAVE command.
7028 * Fixed Remove Channel User payload parsing bug in server's
7029 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
7031 * The server's silc_server_save_channel_key now checks also the
7032 global ID list for the channel as it might not be in the local
7033 list. Fixed a bug related to LEAVE command.
7035 * Is this the end of the [<unknown>] buglet that has been lurking
7036 around for a long time? A little for loop fix in server's
7037 silc_server_command_whois_parse that is used by both IDENTIFY
7038 and WHOIS command. At least, this was a clear bug and a cause
7039 of one type of [<unknown>] buglet.
7041 * WHOIS and IDENTIFY commands call the function
7042 silc_server_command_[whois/identify]_check function even if
7043 we are not router server.
7045 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7047 * Added --with-gmp configuration option. If set the GMP
7048 is always compiled in the SILC source tree. If not set then
7049 it is checked whether the system has the GMP3 installed. If
7050 it has then the GMP won't be compiled (the system's headers
7051 and library is used), if it doesn't have it then the GMP is
7052 compiled in the SILC source tree.
7054 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7056 * Changed RSA private exponent generation to what PKCS #1
7057 suggests. We try to find the smallest possible d by doing
7058 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
7059 not security fix but optimization.
7061 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7063 * Added new config entry [Identity] to fork the server and run
7064 it as specific user and group. A patch from Bostik.
7066 * Imported Dotconf configuration library into lib/dotconf.
7067 This will be used to create the SILC configuration files later.
7068 It will appear in the distsribution after this commit.
7070 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7072 * A big code auditing weekend happening. Auditing code for
7073 obvious mistakes, bugs and errors. Also, removing any code
7076 Removed files for being obsolete:
7078 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
7079 inline in the file lib/silcutil/silcbuffer.h)
7081 o lib/silcutil/silcbufutil.c (the header has inline versions)
7083 Changed code to fix possible error conditions:
7085 o The buffer formatting routines now check that the destination
7086 buffer really has enough space to add the data. This applies for
7087 both buffer formatting and unformatting
7088 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
7089 unformatting was changed to accomodate following rules:
7090 XXX_*STRING_ALLOC will allocate space for the data into the pointer
7091 sent to the function while XXX_*STRING will not allocate or copy
7092 the data into the buffer. Instead it sets the pointer from the
7093 buffer into the pointer sent as argument (XXX_*STRING used to
7094 require that the pointer must be allocated already). This change
7095 makes this whole thing a bit more consistent and more optimized
7096 (note that the data returned in the unformatting with XXX_*STRING
7097 must not be freed now). The routines return now -1 on error.
7099 o Tried to find all code that use buffer_format and buffer_unformat
7100 and added return value checking to prevent formatting and
7101 especially unformatting errors and possible subsequent fatal
7104 o Changed ske->x and ske->KEY to mallocated pointers in
7105 lib/silcske/silcske.h. Fixed possible data and memory leak.
7107 o Added return value checking to all *_parse* functions. Fixed
7108 many memory leaks as well.
7110 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
7111 so that buffer overflows would not happen. All code now also
7112 checks the return value as it can fail.
7114 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7116 * Added reconnection support to server if the normal server looses
7117 its connection to the router (for example if router is rebooted).
7118 The server performs normal reconnection strategy implemented
7119 to the server. Affected file silcd/server.c.
7121 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7123 * Added new packet type SILC_PACKET_SET_MODE that is used to
7124 distribute the information about changed modes (for clients,
7125 channels and clients channel modes) to all routers in the
7126 network. Updated the protocol specification accordingly.
7128 Added functions into silcd/packet_send.c and
7129 silcd/packet_receive.c: silc_server_send_set_mode,
7130 silc_server_set_mode.
7132 Added new files silcmode.[ch] into lib/silccore that implements
7133 the encoding and decoding of Set Mode Payload. Added new type
7134 SilcSetModePayload. Moved the definitions of different modes
7135 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
7137 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7139 * Oops, a little mistake in server's connection authentication
7140 protocol. The protocol is not ended with FAILURE but with
7141 SUCCESS if the authentication is Ok. :) Affected file is
7144 * Implemented NICK_CHANGE notify handling in server in the file
7145 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
7146 the local clients on the channel. After the changing nickname
7147 in router environment snhould work and the [<unknown>] nickname
7148 should appear no more.
7150 The silc_server_replace_id function that receives the Replace ID
7151 payload now sends the NICK_CHANGE notify type also in the file
7152 silcd/packet_receive.c
7154 * Changed WHOIS and IDENTIFY command to support the maximum amount
7155 of arguments defined in protocol specs (3328 arguments). This
7156 fixed a bug that caused problems when there were more than three
7159 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7161 * Added extra parameter, command identifier, to the
7162 silc_client_send_command so that explicit command identifier
7165 Changed that ID list routines uses specific command identifier
7166 when sending WHOIS/IDENTIFY requests to the server so that they
7167 can be identified when the reply comes back.
7169 Affected files lib/silcclient/command.[ch],
7170 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
7172 * Added `sender' argument to silc_server_packet_send_to_channel
7173 to indicaet the sender who originally sent the packet to us
7174 that we are now re-sending. Ignored if NULL. Affected file
7175 silcd/packet_send.[ch].
7177 * Added some server statistics support in silcd/server_internal.h
7178 SilcServerStatistics structure and around the server code. Also
7179 send some nice statistics information when client is connecting
7182 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7184 * Fixed channel ID decoding in server's JOIN command reply in
7185 silcd/command_reply.c
7187 * Fixed braodcasting of replace ID payload to not to send it if
7188 we are standalone server in silcd/packet_receive.c.
7190 * Fixed all channel message sending routines to not to send
7191 packets to clients that has router set, since they are routed
7192 separately in the same function earlier. Affects file
7193 silcd/packet_send.c and all channel packet sending functions.
7195 * In USERS reply, res_argv[i] are not allocated, the table
7196 is allocated. Thus changed that free the table, not its
7199 * In server's whois_check and identify_check if the client is
7200 locally connected do not send any WHOIS commands - they are not
7203 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7205 * Fixed some minor bugs in client when sending WHOIS command. The
7206 arguments was in wrong order.
7208 * Removed statis function add_to_channel from server in
7209 silcd/command.c that was previously used with the joining but
7212 * Tested USERS command in router environment successfully with two
7213 routers, two servers and two clients.
7215 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7217 * Reorganized the USERS command and command reply in client library
7218 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
7219 When the command is given by user we register a pending command
7220 callback that will reprocess the command after the reply has been
7221 received from the server. When reprocessing the packet we then
7222 display the information. Thus, the USERS information is displayed
7223 now in the command callback instead of in the command reply
7224 callback. The processing of the command is same as previously
7225 when server has sent the command reply in the JOINing process.
7227 * Added to USERS command in silcd/command_reply.c to join the client,
7228 we didn't use to know about, to the channel after we've created
7229 a client entry for it. Also, for clienet we did know already still
7230 check whether it is on the channel or not and add it if not.
7232 * Removed silc_server_command_join_notify as the function and its
7235 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7237 * Changed the client's pending command handling to the same as the
7238 server's pending command handling. It is also now possible to
7239 execute command reply functions from other command reply
7240 function as the function callbacks for commands and command
7241 replies are one and same. The pending commands are not static
7242 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
7243 in client connection context. Thus, pending commands are server
7244 connection specific as it is convenient.
7246 Changed the function silc_client_command_pending and
7247 silc_client_command_pending_del and added new function
7248 silc_client_command_pending_check. Removed the
7249 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
7252 * Added cmd_ident, current command identifier, to the client
7253 connection context in lib/silcclient/client.h to keep track on
7254 command identifiers used in command sending. Client's command reply
7255 function handling now supports the mandatory command identifiers.
7257 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
7258 funtions in client to fully support pending command callbacks.
7260 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
7261 as one of the arguments to the application in the command reply
7264 * NOTE: The FORWARDED flag is depracated. It used to be depracated
7265 before first releasing SILC but came back. Now it is removed again
7266 and should come back nomore. The FORWARDED flag was used only
7267 by the JOINing procedure by forwarding the command packet to router.
7268 Now, the JOINing procedure has been changed to more generic (due
7269 to various router environment issues) and FORWARDED is not needed
7270 anymore for anything. The protocol specification is yet to be
7273 Now, removed silc_server_packet_forward from server and the flag
7274 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
7276 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7278 * Renamed NAMES command to USERS command. The NAMES was named that
7279 due to historical reasons. Now it is renamed. Also, rewrote
7280 parts of the USERS command. The nickname list is not sent anymore
7281 by the server. Only Client ID and mode lists are sent in the USERS
7282 command. Changed this also to the protocol specification.
7284 The client now resolves the names and stuff after it receives
7285 the USERS list from the server when joining to the channel.
7287 * WHOIS and IDENTIFY commands has been changed to support multiple
7288 Client ID's per command. One can now search for multiple users
7289 in the network by sending only one WHOIS or IDENTIFY command.
7290 Changed the code and the protocol specifications.
7292 * Removed silc_server_command_identify_parse and changed that IDENTIFY
7293 uses silc_server_command_whois_parse to parse the request. */
7295 * If normal server, do not parse the WHOIS and IDENTIFY requests
7296 before sending it to the router. Saves some time.
7298 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7300 * Fixed JOIN command on client library. Wrong number of arguments
7301 used to crash the client.
7303 * Added silc_server_channel_has_global function to check whether
7304 channel has global users or not.
7306 * Added silc_server_channel_has_local function to check whether channel
7307 has locally connected clients on the channel.
7309 * The silc_server_remove_from_one_channel now checks whether the
7310 channel has global users or not after given client was removed from
7311 the channel. It also checks whether the channel has local clients
7312 on the channel anymore. If it does not have then the channel entry
7313 is removed as it is not needed anymore.
7315 * The silc_server_notify now checks on JOIN notify whether the joining
7316 client is one of locally connected or global. If it is global then
7317 the channel has now global users on the channel and that is marked
7318 to the channel entry. Also, it now saves the global client to
7319 global list who is joining and JOINs it to the channel. This is
7320 for normal server, that is.
7322 Changed silc_server_send_notify_on_channel,
7323 silc_server_packet_relay_to_channel and
7324 silc_server_packet_send_to_channel check if we are normal server
7325 and client has router set (ie. global client) do not send the
7326 message to that client, as it is already routed to our router.
7328 * Implemented LEAVE notify type handling in silc_server_notify
7331 * Tested LEAVE command in router environment successfully. Tested
7332 with two routers, two servers and two clients.
7336 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
7338 * Implemented SIGNOFF notify type handling in silc_server_notify
7341 * silc_server_remove_id now removes the client entry from all channels
7342 it has joined and thusly sends SIGNOFF notify type.
7344 * Rewrote the NAMES list generation in server by removing two excess
7345 loops. The lists are created now inside one loop.
7347 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7349 * silc_server_remove_channel_user checks now also global list
7350 for channel and client.
7352 * silc_server_new_channel_user checks now both local and global
7353 list for channel and client. Fixed a bug in client id decoding.
7354 Used to decode wrong buffer.
7356 * silc_server_channel_message checks now both local and global
7357 list for channel entry.
7359 * Tested channel joining (hence JOIN) in router environment
7360 successfully. Tested with two routers, two servers and two
7363 * Tested channel message sending in router environment successfully.
7365 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7367 * Added silc_server_save_channel_key into server.[ch] to save the
7368 received channel key in Channel Key payload processing. It is
7369 also used in JOIN command reply handling.
7371 Equivalent function silc_client_save_channel_key added into
7372 client.[ch] into client library.
7374 * Changed JOIN command reply to send information whether the channel
7375 was created or not (is existing already) and the channel key
7376 payload. Changed protocol specs accordingly.
7378 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
7379 the request was sent by ID and not by nickname. Crashed on
7382 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7384 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
7385 now correctly save the received data.
7387 * silc_server_free_sock_user_data now notifies routers in the
7388 network about entities leaving the network.
7390 At the same time implemented functions silc_server_remove_id
7391 and silc_server_send_remove_id to receive and send REMOVE_ID
7392 packets. The packet is used to notify routers in the network
7393 about leaving entities. The ID removed will become invalid in
7396 * Added function silc_idlist_del_server into server. Removes and
7397 free's server entry from ID list.
7399 * silc_server_private_message function now checks, if we are router,
7400 that the destination ID really is valid ID, naturally.
7402 * In router when NEW_ID packet is received (for new client) the
7403 hash of the Client ID is saved in the ID Cache but the
7404 client->nickname is set to NULL, instead of putting the hash
7407 IDENTIFY command now also checks that client->nickname must be
7408 valid. If it is not if will request the data from the server who
7409 owns the client. Added new function
7410 silc_server_command_identify_check.
7412 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
7413 to set the command to already allocated Command Payload.
7415 * Tested private message sending in router environment with two
7416 routers, two servers and two clients. Fixed minor bugs and now
7419 * Fixed segfault from client's NAMES command. Used to crash if
7422 * Forwarded packets must not be routed even if it is not destined
7423 to the receiver. Changed server code comply with this.
7425 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7427 * Added `require_reverse_mapping' boolean value to ServerParams
7428 structure. If TRUE (not default) the server will require that
7429 the connecting host has fully qualified domain name.
7431 If the reverse mapping is not required and hostname could not be
7432 found the IP address is used as hostname.
7434 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7436 * Implemented version string checking to both client and server.
7437 The check is incomplete currently due to the abnormal version
7438 strings used in development version of SILC.
7440 * Changed all command functions in server to use the new
7443 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7445 * Changed char *data to unsigned char *data in ID Cache system to
7446 support binary data as ID Cache data. Changed code to support
7447 binary data in lib/silccore/idcache.c.
7449 * Renamed silc_server_packet_relay_command_reply to
7450 silc_server_command_reply as it is normal packet receiving
7451 function. Rewrote the function to accept command replys for
7452 servers and not only for clients.
7454 * Mark remote router always as registered server if we are connecting
7455 to it. Otherwise, commands sent by the router to us are ignored.
7457 * All ID List find routines now returns the ID Cache Entry pointer
7458 as well if requested.
7460 * WHOIS command works now in router environment, tested with two
7461 routers, two servers and two clients.
7463 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
7464 in router environment (as it is almost equivalent to WHOIS) but
7465 hasn't been tested thoroughly. Added new functions:
7467 silc_server_command_identify_parse
7468 silc_server_command_identify_send_reply
7469 silc_server_command_identify_from_client
7470 silc_server_command_identify_from_server
7472 * Disabled route cache adding because adding two different ID's with
7473 same IP replaces the old cache entry thus giving wrong route.
7474 The entry->router->connection is always the fastest route anyway
7475 so route cache may not be needed. Of course, new routes maybe
7476 established after receiving the ID when the entry->router->connection
7477 might not be anymore the most optimal.
7479 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7481 * Add route cache for received ID for fast routing.
7483 * Added silc_server_packet_route to route received packet on router
7484 that is not destined to us.
7486 * Renamed silc_server_get_route to silc_server_route_get.
7488 * Added id_string and id_string_len fields into SilcServer to
7489 include encoded ServerID for fast comparing without excess
7490 encoding of the ID's.
7492 * Cleaned up WHOIS command on server side. Added following static
7495 silc_server_command_whois_parse
7496 silc_server_command_whois_check
7497 silc_server_command_whois_send_reply
7498 silc_server_command_whois_from_client
7499 silc_server_command_whois_from_server
7501 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
7502 arguments in command replies. All command functions should be
7503 updated to use this macro.
7505 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7507 * Minor typo fixes on command reply handling on server.
7509 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7511 * Added silc_server_command_add_to_channel internal routine to add
7512 the client to the channel after router has created the channel and
7513 sent command reply to the server.
7515 * Added generic silc_server_send_command to send any command from
7518 * Use static buffer with ID rendering instead of duplicating data.
7520 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7522 * Fixed a channel user mode bug when joining to a channel server gave
7523 everybody channel founder rights, oops.
7525 * We mark ourselves as the router of the incoming server connection
7526 if we are router ourselves. This way we can check in some packet
7527 sending functions whether it is locally connected server. For
7528 incoming router connections we put NULL.
7530 * For router sending packets locally means now always sending the
7531 packet cell wide; to local clients and local servers. For normal
7532 server sending packet locally means sending it to only local
7535 * Fixed the JOIN command to really work in router environment. If the
7536 channel is created it is always created by the router. Router is
7537 also responsible of making the initial joining to the channel,
7538 sending JOIN notify to the sending server and distributing
7539 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
7540 does not exist server doesn't do anything else but forward the
7541 command to the router which performs everything.
7543 * Added silc_server_send_channel_key function to send the Channel Key
7546 * Added silc_server_create_channel_key to create new channel key. The
7547 channel key is now re-generated everytime someone joins or leaves
7548 a channel, as protocol dictates. Note: channel->key_len is the
7551 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7553 * Splitted server.[ch] finally. Created now packet_send.[ch] and
7554 packet_receive.[ch] to separate packet sending and receiving
7555 routines. The server.[ch] now includes everything else including
7556 actual packet processing (writing and reading data) and other
7559 Renamed silc_server_private_message_send_internal to
7560 silc_server_send_private_message. The routine is still though
7561 used only to relay private messages as server does not send
7562 private messages itself.
7564 Renamed silc_server_new_channel to silc_server_create_new_channel
7565 and added new function sicl_server_new_channel that handles the
7566 incoming New Channel packet. Added also new sending function
7567 silc_server_send_new_channel to send New Channel Payload.
7569 * Added new function silc_server_notify to process incoming notify
7570 packet to the server/router. Server may then relay the notify
7571 to clients if needed.
7573 * Added new function silc_server_new_channel_user to process incoming
7574 New Channel User packet. Router will redistribute the packet and
7575 send JOIN notify to its local clients and locally connected servers
7576 if needed. Normal server will send JOIN notify to its local client
7577 on same channel when received this packet. Added also corresponding
7578 sending function silc_server_send_new_channel_user to sent the
7581 * Added boolean route argument to send_notif_to_channel and
7582 packet_send_to_channel functions to attempt to route the packet
7583 if it is TRUE and send only locally if it is FALSE.
7585 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7587 * silc_server_replace_id now broadcasts the received replace ID
7588 packet if it is not broadcast packet already. The router must
7589 broadcast to inform other routers about changed ID.
7591 * Added backpointer to server's router into SilcServer context in
7592 silcd/server_internal.h.
7594 * Fixed silc_server_packet_broadcast to send correct broadcast
7597 * The channel key is now distributed to the local client as soon
7598 as it is received from the router (in router environment) so that
7599 no other packet may be sent for the channel until client has
7602 * silc_server_remove_channel_user now broadcasts the received
7603 Remove Channel User packet if it is not broadcast packet already.
7604 The router must broadcast to inform other routers about removed
7607 * Added users field into SilcPacketContext that is a reference count
7608 of the context. One can increase the reference count by calling
7609 silc_packet_context_dup which is now changed to just increase the
7610 reference count instead of duplicating the data. The reference
7611 count is decresed by calling silc_packet_context_free that will
7612 free the data after the reference count hits zero.
7614 For now on the packet context and everything allocated into it
7615 (including the raw packet from network) must be freed by calling
7616 the new silc_packet_context_free function. Added also new function
7617 silc_packet_context_alloc that must be used now to allocate the
7618 context. This also means that if a routine is asynchronous from
7619 silc_[client/server]_packet_parse_type the packet context must
7620 be duplicated by calling silc_packet_context_dup. Otherwise it
7621 gets free'd after silc_[client/server]_packet_parse_type returns.
7622 Also, one must remember that if packet is duplicated then its
7623 reference count must be decresed by calling the free function as
7624 many times as it was duplicated.
7626 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7627 from both client and server.
7629 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7631 * Made joining to a channel working in router environment.
7633 * Cleaned up JOIN command on server side and create function
7634 silc_server_command_join_channel internal routine to make the
7637 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7639 * Changed silc_command_pending list to SilcDList. Also, added
7640 `ident' field to SilcServerCommandPending structure to identify
7641 the reply and to call correct callback.
7643 Added silc_server_command_pending_check function to replace the
7644 corresnponding macro. The silc_command_pending list is not
7647 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7648 to set identifier to previously allocated Command Payload. It
7649 is used to set identifier for command when resending Command
7652 * Added silc_command_payload_encode_payload to encode Command
7653 Payload buffer from SilcCommandPayload structure.
7655 * Added silc_argument_payload_encode_payload to encode Argument
7656 payload buffer from SilcArgumentPayload structure.
7658 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7660 * Changed WHOIS command to support router connection on server side.
7661 The whois request is always sent to router unless the server is
7662 standalone server. After server has received the reply from the
7663 router will it send the reply to the client.
7665 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7666 broadcast received broadcast packet. The function is used only
7667 by router. The broadcast packet is always sent to the router's
7670 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7671 render given ID to printable string, for log files for example.
7673 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7675 * Made basic router to router connections working. At least they
7676 can now connect to each other but nothing really works the way
7677 they are supposed - yet.
7679 * Added new initiator token to RouterConnection configuration
7680 file in silcd/serverconfig.[ch]. It is used to tell whether we
7681 are the initiator to the remote router or whether we'll expect
7682 the other end to connect.
7684 * Moved registering of listener task to silc_server_init, hence
7685 the server starts listenning as soon as it is run, even if it
7686 does not have connections to other routers. Let's see how well
7689 * Changed default connection retry timeouts for more suitable in
7692 * Removed cipher and such arguments from silc_idlist_add_client
7693 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7694 Added new function silc_idlist_add_data to add the keys and stuff
7697 * Added SilcIDListData structure and added it to SilcClientEntry
7698 and SilcServerEntry as their first field in the structure. This
7699 way we can explicitly cast the ID entries to the SilcIDListData
7700 structure and get common data for the entries. In past, we had
7701 to first check what type of connection it is and then cast it to
7702 correct ID entry type. Now, we can directly cast the opaque
7703 pointer to the SilcIDListData (no matter what ID entry it actually
7704 is) and get the data needed.
7706 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7708 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7709 in some circumstances even if threre were timeout tasks, though not
7710 IO tasks, but tasks anyway. Now fixed.
7712 * Defined SilcServerConnection structure to hold connection specific
7713 stuff about directly connected servers and routers. The definition
7714 is currently in silcd/server_internal.h. I thought about having
7715 a bit more important role fro this struct but for now it is used
7716 only when connecting to other server (or router actually).
7718 * Added connecting retry support in server when connecting to
7719 router(s). The retry feature implement exponential backoff
7720 algorithm. Also, added SilcServerParams structure to hold default
7721 parameters for server. For now, it include these retry settings
7722 and are hard coded. After server is moded to be as Silc Server
7723 Library this structure will be more important.
7725 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7727 * Changed client librarys channel->clients table to SilcList and
7728 changed code accordingly.
7730 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7732 * Changed client's channel table to SilcList and changed code
7733 accordingly. Also changed SilcChannelClientEntry to include back-
7734 pointer to the channel so that client entry can use that structure
7735 as list as well and we have fast cross-reference to the channel.
7736 This change dramatically decreased the complexity of channel
7737 handling with client entry and vice versa (removed one extra
7738 loop when searching for channel entry from many functions).
7740 * Changed server->sim from table to SilcDList and changed code
7743 * NAMES command can now be used from user interface. It will show
7744 the user list on the channel, neatly.
7746 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7747 Code now saves realname of the user if it becomes available.
7749 * Renamed configure.in to configure.in.pre and made ./prepare
7750 script to automatically add correct version string to
7751 configure.in which it creates from configure.in.pre.
7753 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7755 * NAMES command reply now shows users mode with the nickname when
7758 * Moved silc_client_ch[u]mode[_char] functions from
7759 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7760 place sucks, they are utility functions and should be in some
7763 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7765 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7768 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7772 * Added TRQ (efficient deque and list library) into lib/trq. This is
7773 a very good list library that is currently used in the SILC. Defined
7774 SilcList API over the library because I didn't like the API very
7775 much. See lib/trq/silclist.h for the API and examples of how to
7776 use the API. Fixed various places in the code to use the new
7777 SilcList API. The SilcList is meant for lists that has a structure
7778 already defined as a list. It is not suitable to add just some
7779 context to the list (in TRQ, the context is the list actually).
7781 So, I defined SilcDList that can be used for the purpose where
7782 predefined list structure does not exit. This can be used as
7783 such list. Now some context just can be added to the SilcDList.
7784 Currently this list is not used in the SILC just yet, though there
7785 are a lot places where this can replace dynamically allocated
7786 tables and I will fix these places, later, to use SilcDList.
7787 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7788 and use TRQ internally).
7790 Also fixed some annoying warning messages that the original TRQ
7791 code generated. Also minor changes to TRQ's Makefile.in.
7793 * Added support for querying by Client ID to both WHOIS and
7794 IDENTIFY commands into server, as required by the protocol.
7796 * Removed method function pointers from SilcBuffer structure. They
7797 weren't used to anything and just increased the context size for
7798 no good reason. This change also made silc_buffer_alloc and
7799 silc_buffer_free functions inline functions.
7801 * Disabled command flooding detection support until it's fixed so
7802 that it accepts commands in but does not execute them more than once
7805 * Added silc_net_localhost(), to return local hostname, into
7806 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7807 that must be initialized before calling silc_client_init.
7809 * Added new function: silc_server_send_notify_on_channels to send
7810 notify messages to all channels client has joined. It is assured
7811 that the message is sent only once per client.
7813 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7814 lib/silcutil/silcutil.[ch] as silc_format function. The new
7815 function is generic and is used by server as well, not only by
7816 the logging routines.
7818 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7819 the provided version string was not acceptable. Added new function:
7820 silc_ske_check_version into lib/silcske/silcske.h. The function
7821 must be implemented by the application (client or server) and it
7822 does not reside in the SKE library. The function checks the version
7823 string remote end sent.
7825 * Added back pointers (to opaque context and to SilcSocketConnection)
7826 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7828 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7829 duplicate packet context structure.
7831 * Changed `notify' client operation to send same arguments as client
7832 receives from server except for ID's. ID's are mapped to correct
7833 ID entry and that is returned. Also, if channel entry is not sent
7834 by server but the notify is for channel the channel entry is sent
7835 to application (otherwise application doesn't know that it is for
7836 channel (library gets it from packet's Destination ID)).
7838 * Added silc_client_remove_from_channels into client library to
7839 remove a client from all channels it has joined to. Used when
7840 received SIGNOFF notify from server. Added also new function
7841 silc_client_replace_from_channels to replace old ID entry with
7842 new ID entry on all channels. Used when received NICK_CHANGE
7845 * Fixed ID Cache list handling in silc_idlist_get_client in
7846 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7847 to get (or query) client by ID.
7849 * Updated TODO list.
7851 * Added connection authentication status message defined by the
7852 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7853 support for these into the code in client and server side.
7855 * Added generic function silc_client_send_command to send any command
7856 with variable argument list. Application should use this function
7857 to send commands if the command functions provided by the library
7858 does not suite for the application's user interface needs.
7860 * Added new `failure' client operation. Application is notified about
7861 received failure packet if client is executing a protocol. In this
7862 case the protocol's execution has failed.
7864 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7865 is required by the protocol.
7867 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7868 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7871 * Added status flag to SilcSKE object to indicate realtime status
7872 of the SKE protocol.
7874 * Application receives now exactly same command reply arguments as
7875 the library receives from server. However, if ID is received the
7876 corresponding ID entry is returned to the application (eg. Client
7877 ID is mapped to correct SilcClientEntry entry and that is returned).
7878 Changed command_reply client operation due to this change.
7880 * Changed all ID's in commands and in command replys as ID Payloads.
7881 Change affected both client and server side codes.
7883 All ID's sent in SILC network (with execption of ID's in SILC
7884 Packet header) are sent in ID Payload to support variable length
7887 * Server now notifies nick changes and notifies all clients on
7888 the channels about the new nickname (about the new Client ID,
7891 * Implemented CMODE command to change channel modes. Supports all
7892 channel modes defined by the protocol specs except ban and invite
7893 lists. (Also, private channel key mode is supported but support for
7894 setting private channel key in client is missing, thus, this mode
7895 has no effect on client side (except that server requires that the
7896 client uses private channel key and normal channel traffic does not
7899 Also, invite mode works per se, but INVITE command does not work
7900 yet correctly, so you can set channel as invite only channel but
7901 inviting clients to the channel does not work (it is yet to be
7902 thought what's the best way to do it).
7904 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7905 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7906 Implemented CUMODE command to change user's mode on the channel.
7907 Supports all modes defined by the protocol specs.
7909 * Added NAMES command reply to return users modes on the channel.
7911 * Removed unnecessary and slow ciphers from lib/silccrypt.
7913 * Set SO_KEEPALIVE option to connection sockets by default.
7915 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7917 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7918 redefined the Notify Payload into protocol specs.
7920 * Added silc_id_payload_parse_id to get ID directly from raw
7923 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7925 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7926 accept searching by Client ID as well.
7928 * Added support for LEAVE and SIGNOFF notify types in client library.
7930 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7931 to parse ID Payload from raw data.
7933 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7935 * Added flags parameter into silc_ske_assemble_security_properties
7936 function in lib/silcske/silcske.[ch].
7938 * Changed notify client operation to fit better for notify messages
7939 sent by server. The notify payload received from server is now
7940 passed to the application (after parsing it to SilcNotifyPayload).
7941 It is application's responsibility to retrieve the arguments
7942 from the payload and show the message the way it wants. The message
7943 sent by server is implementation specific.
7945 * Changed public keys to comply with the protocol specification.
7946 Old public keys are not supported anymore and are not compatible.
7948 * Removed nickname from Channel Payload as the latest draft removed
7949 it. The client must resolve the nickname from the NAMES command
7950 reply received when it joined the channel.
7952 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7954 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7956 * Fixed some errors in protocol specification drafts.
7958 * Created lib/silccore/silcnotify.c to implement Notify Payload
7959 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7960 generic payloads described by protocol specifications. The file
7961 includes implementations for ID Payload and Argument Payload.
7963 * Changed Command Payload implementation to use the new Argument
7964 Payload. Changed command_xxxx_payload to command_payload_xxxx
7965 to comply with SILC coding conventions.
7967 * Added suppport for Argument Payload handling in Notify Payload
7968 implementation as protocol requires it. Added the new support
7969 into server and client lib as well.
7971 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7973 * Added support for multiple nicknames on same channel. [n] is
7974 added locally to the nickname if there are more than one same
7975 nicknames on the channel.
7977 * Server now sends all nicknames that matched WHOIS request.
7978 Client also shows the list received from server.
7980 * Added TOPIC command to client side. User can now set and show
7981 current topic on channel.
7983 * Added MOTD command to client and server. Also, server sends the
7984 motd when client connects to the server.
7986 * Changed version strings to comply ISO 8601.
7988 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7990 * Fixed protocol error handling in client library. It should now
7991 cope even if the SKE fails for some reason.
7993 * Made new protocol specification drafts for submitting to IETF.
7995 * Implemented TOPIC command to server in silcd/command.c.
7997 * Added two new notify types into lib/silccore/silcnotify.h:
7998 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
7999 notify nickname change and topic setting/change on a channel.
8001 * API change of command_reply operation in client library. The
8002 application gets now the status type received from server as well.
8004 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8006 * Removed the function just added to lib/silcutil/silcschedule.[ch].
8008 * Cras fixed and optimized the packet handling even further and
8009 it should work now. Minor change to the prototype of function
8010 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
8012 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8014 * Added new function into lib/silcutil/silcschedule.[ch]:
8015 silc_schedule_with_fd to select() a specified fd. The function
8016 returns after timeout expires or data arrives or goes. The
8017 function is used by packet routines to wait that all data is
8018 received from network.
8020 * Fixed data reading from network in lib/silccore/silcpacket.c.
8021 The code now assures that all data is read from the fd and then
8022 continues packet processing. This was a bug fix since the code
8023 used to drop some data in some circumstances.
8025 * Added new function into lib/silcclient/client.[ch]:
8026 silc_client_start_key_exchange to start key exchange after
8027 connection has been established to server. The code internally
8028 now uses this funtion but its main purpose was to provide it
8029 for applications that perform their own connecting. After
8030 application has created a connection it merely calls this
8031 function to start the key exchange between client and server.
8032 The library takes care of everything else after that.
8034 Updated also lib/silcclient/README to explain the usage of
8037 * Do not send to application information that connection has
8038 been established. Application gets notified it by connect
8041 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8043 * Applied cras's patch to add silc_schedule_one function. The
8044 function runs scheduler once and returns.
8046 * Fixed the scheduler after cras messed it up. The timeout
8047 handling works now as it's supposed to work.
8049 * Added into lib/silccore/ silcnotify.h to include notify
8050 message types support. Changed silc_server_send_notify*
8051 functions, in server.[ch], to support those new notify types.
8052 Added the support for the notify types into client library,
8053 as well. Added new notify client operation into ops.h in
8056 * Changed silc_server_packet_send_to_channel to send normal
8057 packets instead of just channel message packets. The function
8058 is now used to send the notify packets to channels. It is not
8059 used to send channel message packets anymore, as server never
8062 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
8063 va_arg()s as it seems to require it nowadays. I guess, if SILC
8064 is compiled with older va_arg() the new code should work anyway.
8066 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8068 * Splitted core library. Core library (lib/silccore) includes
8069 now only SILC protocol specific core (and common) components.
8070 Created new utility library (lib/silcutil) that includes more
8071 generic purpose stuff. The stuff for util library was taken
8072 from the old core library. This was minor and easy split.
8074 * Created SILC Client Library (lib/silcclient) that includes
8075 implementation of the SILC client without user interface. This
8076 was major move from silc/ directory. The code has been changed
8077 so that it is transparent towards the user interface. The
8078 silc/ directory includes now the same user interface as before
8079 and it uses the new client library. Read lib/silcclient/README.
8080 Basicly, the client library performs everything else related
8081 to SILC except user interface handling. Also, configuration
8082 files are considered to be part of user interface and library
8083 does not handle them.
8085 This change also changed a lot of structures, function naming etc.
8086 Most important change was that SilcClientWindow object was
8087 renamed to SilcClientConnection in the client library. Created
8088 also new file lib/silcclient/ops.h. Also added new files
8089 silc/local_command.[ch] and silc/client_ops.[ch].
8091 All these changes were made to make it easier for user interface
8092 designers to create what ever user interface for the SILC client
8095 It is also expected that the server will be moved to lib
8096 directory as well and SILC Server Library will be created;
8097 sometimes in the future.
8099 * Removed Local commands from lib/silccore/silccommand.h as
8100 they are application specific and new client library does not
8101 handle any of those anymore.
8103 * Several functions moved to lib/silcutil/silcutilc.[ch] from
8104 old client implementation in silc/.
8106 * Added support for callback functions in SILC_LOG_* macros.
8107 Application can now set its own callbacks that will be called
8108 instead of using the default functions that will always print
8109 the debug messages to stderr (or stdout). Also, debugging can
8110 now be disabled by setting silc_debug to FALSE and re-enabled by
8111 setting it to TRUE. Note, that logging will still work even
8112 if debugging is disabled.
8114 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
8115 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
8116 silc_log_reset_debug_callbacks.
8118 * To enable debugging in silc client one must give now -d
8119 option on command line.
8121 * Changed silc_schedule_init to automatically allocate task queues
8122 if they are not allocated before calling it.
8124 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8126 * Added GMP 3.1 into math library.
8128 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8130 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
8131 a channel in SILC network. The packet is used by servers and
8132 routers to notify other routers that user has left a channel.
8133 This little feature was missing until now. Added the feature
8134 to protocol specification as well.
8136 Added functions: silc_server_send_remove_channel_user and
8137 silc_server_remove_channel_user into server.[ch].
8139 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
8140 lib/silccore/silcpacket.h. However, they are not implemented
8143 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8145 * Fixed joining to a channel and sending channel messages
8146 between server and router. The channel message sending should
8147 now work inside a cell.
8149 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8151 * Fixed the private message sending between server and router.
8152 The private message sending should now work inside a cell.
8154 * Added silc_server_replace_id into server.[ch] to replace
8155 existing ID in the SILC network.
8157 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
8158 and silc_idlist_replace_server_id into idlist.[ch] in server.
8160 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8162 * Fixed the server to server connections. Server can again now
8163 connect to router. Router to router connections probably does
8166 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8168 * Added dynamic protocol registering support. Now protocols can
8169 registered and unregistered on the fly. Patch by cras.
8171 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8173 * Added lib/contrib directory to hold routines that some platforms
8174 don't have but are needed by SILC.
8176 * Added getopt.c, getopt1.c and getopt.h from GNU C library
8177 into lin/contrib to provide getopt() and getopt_long() for
8178 those who don't have it.
8180 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8182 * Added AWAY command to client. When away message is set and
8183 client receives a private message packet the client automatically
8184 replies to the sender with the away message.
8186 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
8187 bug seemed to be the cause of recent problems when compiling
8190 * Added version detection support to SKE protocol specification
8191 and added the new changes to the SKE implementation as well.
8192 There were other minor changes in the SKE protocol as well.
8194 Many changes in lib/silcske/silcske.[ch] and in
8195 lib/silcske/payload.[ch].
8197 * Added ^U functionality, clear input line. Patch from cras.
8199 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8201 * Mainly small bugfixes on core library. Fixed some debugging
8202 logging and buffer overflow in silclog.c.
8204 * Updated config.sub and config.guess on the distribution tree.
8206 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8208 * Added command lagging support in server. Client may execute
8209 commands now only once in two seconds.
8211 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8213 * Optimized packet reception. MAC computation and checking is now
8214 also more optimized. A lot previously duplicated code is now
8215 used as generic by both client and server.
8217 * Fixed key pair generation in clientutil.c
8219 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8221 * Added into lib/silccore/silcbufutil.[ch] new function;
8222 silc_buffer_realloc.
8224 * Moved generic packet sending/encryption functions to
8225 lib/silccore/silcpacket.[ch] from client and server. Some
8226 rewriting of the functions.
8228 * Moved all generic packet reception/decryption functions to
8229 lib/silccore/silcpacket.[ch] from client and server. The
8230 packet processing is now much cleaner in both client and server.
8231 These were major changes in both client and server.
8233 * Created many common functions in server to do packet sending.
8234 Previously code were duplicated a lot, this has been removed
8237 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8239 * Rewrote major parts of the ID cache system. Don't know
8240 whether it is better now or not but at least the API is more
8243 * Major rewrite on ID cache stuff on client because of the ID
8244 cache API changes. Added idlist.c to client.
8246 * Also major rewrite on ID cache stuff on server as well.
8247 Major rewrite of idlist.[ch]. SilcXXXList's are now named
8248 SilcXXXEntry's. We won't keep anymore idlist specific pointers
8249 in hand, instead they are all put into the ID cache system now.
8250 All server_idlist_* routines uses ID cache now instead of
8251 traversing its own lists (those lists does not exist anymore).
8252 SilcIDList though still exists. Also, SilcXXXEntry's are
8255 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8257 * Finally made the SKE implementation compliant to the protocol
8258 specification. All mp integers are now binary encoded as
8259 opposed being HEX encoded.
8261 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
8264 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
8265 functions: silc_[encode/decode]_pem. Also added function
8266 silc_encode_pem_file to PEM encode with newlines ('\n') for
8269 * SILC public keys are now encoded either PEM or binary. Same
8270 option is for private keys as well. By default private keys
8271 are binary encoded and public keys PEM encoded. Silly HEX
8272 encoding were removed.
8274 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
8275 function to create fingerprints.
8277 * Fixed a bug in SHA1; does not change the original data anymore.
8279 * Partly implemented INFO command on client and server side.
8280 Fixed CLEAR command. Changes to SERVER command; show current
8281 server(s) when giving command without arguments. Added
8282 VERSION command to client.
8284 * Added check to server that unregistered connections cannot
8285 execute commands (unless it is specificly allowed).
8287 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8289 * Fixed screen refresh.
8291 * Fixed channel joining bug from client. On some circumstances
8292 client tried to join to a channel it had already joined.
8294 * Added public key verification process into client's protocol.c.
8295 The client now verifies the public key from user and saves
8296 it into ~./silc/serverkeys/ directory.
8298 Added into: clientutil.[ch]: silc_client_verify_server_key.
8300 * Changed SKE protocol's silc_ske_initiator_finish function
8301 to accept callback function that verifies the received public
8302 key. Removed old silc_ske_verify_public_key function.
8304 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8306 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
8307 silc_pkcs_private_key[_data]_set.
8309 * Made the password and public authentication more cleaner in
8310 server's protocol.c.
8312 * Removed historic and obsolete protocol `channel_auth' from
8313 both client and server.
8315 * Removed wrong way of sending command status messages from
8316 server to client in server's command.c. The old way violated
8317 protocol specification.
8319 Changes to silccore/silccommand.[ch]: removed
8320 silc_command_encode_status_payload -> not needed anymore,
8321 changed silc_command_encode_payload_va to accept extra
8322 argument on variable argument list. The argument type must
8323 now be provided to the function. Also, added new function:
8324 silc_command_encode_reply_payload_va which is same as
8325 normal command_encode_payload_va except command status type
8326 is provided as extra argument.
8328 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8330 * Added ~./silc directory handling. The directory includes the
8331 public and private keys for the client.
8333 Added silc_client_check_silc_dir, silc_client_create_identifier
8334 and silc_client_load_keys.
8336 * Implemented SILC protocol compliant public key. Added public
8337 and private key saving to and loading from files.
8339 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
8340 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
8341 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
8342 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
8343 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
8345 Implemented: silc_pkcs_save_[public/private]_key[_data] and
8346 silc_pkcs_load_[public/private]_key.
8348 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8350 * Added silc_server_get_route (route.[ch]) to get connection
8351 data for the fastest route for given ID.
8353 * Implemented INVITE command on client and server. The command
8354 were re-defined in the SILC Protocol Specification and the
8355 implementation now complies with the specification.
8357 * Implemented PING command on client and server.
8359 * Implemented NAMES command on client and server. The server side
8360 supports currently only normal server not router server yet.
8361 Some changes to NAMES definition in SILC protocol specification.
8363 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8365 * Implemented LEAVE command on client and server.
8367 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
8368 again. This change was made to the protocol as well. Server
8369 should not violate the protocol specification anymore.
8371 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8373 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
8374 was tested. SOCKS4 was not but should work anyway.
