508 Affected file silcd/protocol.c.
510 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
512 * Some client implementations quit network by doing first LEAVE
513 and then immediately SIGNOFF (like Bombyx). We now do check
514 after a short time after LEAVE notify and check whether the
515 client is still valid after LEAVE, and if not we remove it from
516 cache. Affected file is lib/silcclient/client_notify.c.
518 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
520 * Merged version 1.1.4 of zlib. Even if it not currently in use,
521 it's good not to have security holes here.
523 * Fixed a negative refcount situtuation for the config context.
524 Affected file is silcd/serverconfig.c.
526 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
528 * ROBOdoc documented lib/silcutil/silcutil.h.
530 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
532 * Optimized even more the SilcPacketContext structure. Now
533 totally saved 16 bytes of memory per context after optimization.
534 Affected files are lib/silccore/silcpacket.[ch].
536 * Made strict checks for valid SILC IDs. Affected file is
537 lib/silccore/silcid.c.
539 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
541 * Changed the object argument for silc_cipher_register,
542 silc_hash_register, silc_hmac_register and silc_pkcs_register
543 to const. Affected files are lib/silccrypt/silccipher.[ch],
544 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
546 * Changed the silc_get_username and silc_get_real_name to
547 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
549 * Fixed the Irssi SILC Client to use the silc_get_username and
550 silc_get_real_name insted of glib routines since the glib
551 routines only corrupt stack. Fixes the Irssi SILC to work in
552 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
554 * Fixed the Irssi to not use g_get_home_dir since it crashes
555 or returns garbage on cygwin and corrupts stack. Added function
556 get_home_dir to Irssi routines. Affected files are
557 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
559 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
561 * Made some structure optimizations. SFTP memory FS MemFSEntry
562 entry structure. Optimized SilcTask structure. Optimized
563 SilcPacketContext structure.
565 Affected files lib/silcsftp/sftp_fs_memory.c,
566 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
568 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
570 * And yet again reverted back the config thing since Johnny
571 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
574 * Fixed memory leaks from config object. Affected files are
575 silcd/serverconfig.[ch].
577 * Added support for adding new connections to the server in rehash.
578 After rehash they take effect.
580 Added support for changing the maximum allowed connections in
581 rehash. The number can grow but going smaller is not supported.
583 Added function silc_server_num_sockets_by_remote to the
584 silcd/server_util.[ch].
586 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
588 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
590 * Added preliminary checking during config parsing for a valid
591 public/private key and removed further checks in the code.
592 Affected files are silcd/serverconfig.[ch], server.c.
594 * Moved functions silc_server_drop() and silc_server_daemonise()
595 from server.c to silcd.c since they are stricly related to
596 the application activity.
598 * Reverted a small part of the automatic ref/unref since
599 it caused a double unref in some situations. Affected
600 files are silcd/silcd.[ch], server.c, serverconfig.c.
602 * Added some .cvsignore files in the lib directory.
604 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
606 * Fixed silc_net_gethostbyaddr to correctly resolve by
607 address. Affected file lib/silcutil/silcnet.c.
609 * Fixed the notify relaying to client. The HMAC to be used
610 with relayed packets ws wrong and caused decryption failure
611 at the client end. Affected file is silcd/packet_receive.c.
613 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
615 * Created new branch silc_protocol_1_0_branch.
617 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
619 * Changed the silc_server_config_* routines to be SilcServer
620 independent. They are now officially application specific code
621 and not part of generic server implementation. Affected files
622 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
624 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
626 * Added automatic referencing of config context in the
627 silc_server_config_alloc, and automatic unreferencing in the
628 silc_server_config_destroy. Affected files are
629 silcd/serverconfig.[ch], silcd/silcd.c.
631 * Fixed the silc_log_quick handling in the logging routines.
632 It didn't log quickly when it was TRUE. Affected file is
633 lib/silcutil/silclog.c. Also the flush delay was set even
634 if it was 0 in config file. Affected file is
635 silcd/serverconfig.c.
637 * Added support for changing key pair of the server in rehash.
638 Affected file silcd/server.c.
640 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
642 * Fixed the TOPIC_SET notify to not cras. It changed the topic
643 too early, before getting the channel entry. Affected file
644 is silcd/packet_receive.c.
646 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
648 * Added functions silc_server_config_[ref/unref], these are used
649 to prevent that the config object is destroyed.
651 No longer directly affect global variables silc_log_quick and
652 silc_log_delay, they are first cached inside the config object
653 and then applied with silc_server_config_setlogfiles().
655 silc_server_config_set_defaults() is now internal to
656 serverconfig.c, there are no reasons to show this internal stuff
659 Affected files are silcd/serverconfig.[ch].
661 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
662 fprintf's to stderr, since some code may be executed again after
663 the server went into the background. Affected files are
666 * Added rehash support. Added function silc_server_rehash() that
667 will perform all the basic tasks of the rehashing procedure.
669 * Added command line option `-x, --hexdump'. This will enable the
670 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
671 The option `--hexdump' implies `--debug'.
673 * Fixed a bad bug in the logging APIs (silcutil library) where
674 the application would crash after calling silc_log_reset_all().
676 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
678 * Fixed the KICKED notify handling in client library to
679 correctly remove the channel and all entries from the
680 channel when I was kicked. This bug crashed the client.
682 Fixed yet another but in KICKED notify handling to remove
683 the kicked client correctly from the channel.
685 Affected file is lib/silcclient/client_notify.c.
687 * Fixed a minor bug in looking up correct client entry
688 in KICKED notify in server. Affected file is
689 silcd/packet_receive.c.
691 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
692 sources correctly to distribution. Fixes --with-gmp option.
694 * Removed the manual rehashing from ID Cache, and changed it
695 to use the SILC Hash Table's auto rehash feature. Affected
696 file is lib/silccore/silcidcache.c.
698 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
700 * Fixed a bug in the silc_client_nickname_format function that
701 handles the multiple same nickname formatting. Two clients
702 with same nickname caused problems after the first one left
703 and rejoined. It didn't format the nickname correctly.
704 Affected file is lib/silcclient/idlist.c.
706 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
708 * Don't change the topic if olod topic is same as new one.
709 Affected file is silcd/packet_receive.c.
711 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
713 * Added cross-reference support to the SILC Documentation
714 generator. All types across all HTML files are now cross-
715 referenced. Affected files util/robodoc/generator.c and
716 scripts/silcdoc/silcdoc.
718 * Added file lib/silcutil/silctypes.h to include all the
719 arithmetic type definitions and some macros. Removed
720 includes/bitmove.h and moved macros to silctypes.h.
722 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
724 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
726 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
728 * Added `type' argument to silc_id_payload_parse_id function which
729 now returns the type of the ID to the sent pointer. Affected
730 file is lib/silccore/silcid.[ch].
732 * Added check for CMODE_CHANGE notify type that mode change is
733 allowed by the sender. Affected file silcd/packet_receive.c.
735 * Added check for CUMODE_CHANGE notify type that mode change is
736 allowed by the sender. Affected file silcd/packet_receive.c.
737 Added the ID type as CUMODE_CHANGE notify type as argument
738 to the `notify' client operation. Affected files are
739 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
741 * Added function silc_client_add_server to the client library.
742 Added support for resolving also channel and server info when
743 received unknown entity in notify packet. Affected files are
744 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
746 * Added function silc_command_get_status to return the command
747 status from the command reply's argument payload. Affected files
748 are lib/silccore/silccommand.[ch].
750 * Added check for KICKED notify type that the kicking is
751 allowed by the client. Affected file silcd/packet_receive.c.
753 * Created function silc_get_input which can be used to get input
754 (echo on or off) from user on command line. Affected files are
755 lib/silcutil/silcutil.[ch].
757 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
759 * Optimized silc_server_packet_relay_to_channel function.
760 Added new function silc_channel_message_payload_encrypt which
761 can be called directly if channel message payload needs to
762 be encrypted and is already encoded (no need to call _encode
763 function). Packet relaying is now done by router without any
764 extra memory allocations. Affected files are
765 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
768 * Fixed the INVITE notify handling. It took wrong arguments
769 as invite list and invite delete. Affected file is
770 silcd/packet_receive.c.
772 * Added check for TOPIC_SET notify type that the topic change is
773 allowed by the client. Affected file silcd/packet_receive.c.
775 * Added check for INVITE notify type that inviting is allowed by
776 the client. Affected file silcd/packet_receive.c.
778 * Changed the silc_server_client_on_channel to return the
779 SilcChannelClientEntry as well. Moved the function
780 silc_server_check_cmode_rights to server_util.[ch].
781 Affected files are silcd/server_util.[ch], silcd/command.c.
783 * Added function silc_server_check_umode_rights to check whether
784 changing client's user mode is allowed. Added check for
785 UMODE_CHANGE notify type that the umode change is allowed
786 by the client. Affected files are silcd/server_util.[ch],
787 silcd/packet_receive.c and silcd/command.c.
789 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
791 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
792 ID length. It ignored that ID can be IPv6 based as well.
793 Affected file lib/silccore/silcpacket.h.
795 * Fixed the silc_id_id2str and silc_id_str2id to take the
796 IPv6 address offset's into consideration. Affecte file is
797 lib/silccore/silcid.c.
799 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
801 * Fixed the internal Unix scheduler functions to check for
802 NULL context they may receive. The affected file is
803 lib/silcutil/unix/silcunixschedule.c.
805 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
807 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
808 can specify different directory with --home command line
809 parameter. Affected files irssi/src/silc/core/client_ops.c,
812 * SILC-specific commands aren't now executed if the active server
813 isn't of SILC-type, so there won't be problems with having
814 IRC and SILC protocol support in same client. Affected files
815 irssi/src/silc/core/silc-channels.c, silc-servers.c,
818 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
820 * Improved the signal support in SILC Schedule. Added new
821 function silc_schedule_signal_call which is used by application
822 to mark a signal to be called. It is now safe to perform
823 any kind of tasks in signal callbacks since it is guaranteed
824 that the application specified signal callback is called
825 after the signal is over. Affected files are
826 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
828 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
830 * Added `name' field to SilcChannelPrivateKey to represent
831 application given name for the key. Moved also the context from
832 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
833 Added the `name' argument also to the function
834 silc_client_add_channel_private_key.
836 Added function silc_client_current_channel_private_key to set the
837 current channel private key in use.
839 Added "change" command to KEY command which can be used to change
840 the current channel private key. Bound the command also to
843 Also affected files lib/silcclient/client_channel.c,
844 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
846 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
848 * Added silc_rng_get_byte_fast function in to the
849 lib/silccrypt/silcrng.[ch].
851 * Changed the interface of silc_packet_assemble and the
852 silc_packet_send_prepare. If silc_packet_assmble is now
853 called the application does not call silc_packet_send_prepare
854 because the library will call it automatically. These
855 interfaces now also return a reference to the outgoing buffer
856 which includes the assembled packet, which the application can
857 use to encrypt the packet.
859 Affected files are lib/silccore/silcpacket.[ch],
860 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
861 silcd/packet_send.c, server_backup.c and packet_receive.c.
863 * Fixed a packet sending bug on very high load, where outgoing
864 packet queue wasn't handled correctly and packets got corrupted.
865 Affected files are lib/silcutil/*/silc*sockconn.c,
866 lib/silcclient/client.c and silcd/server.c.
868 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
870 * Added macro SILC_PACKET_DATALEN which can be used during
871 packet assembling to check whether the data to be added to
872 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
873 len is truncated until it fits it.
875 Added checks for maximum length of channel message payload and
876 private message payload also.
878 Added checks for maximum packet length in server and in
881 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
882 lib/silcclient/client.c, lib/silccore/silcchannel.c and
883 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
884 lib/silcclient/client_prvmsg.c.
886 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
888 * Added silc_server_packet_queue_purge call to the
889 silc_server_disconnect_remote to assure that all data in the
890 queue before disconnecting is sent to the network. Affected
893 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
895 * Added the deleting of server's own ID cache entry to the
896 silc_server_free function. Free also everything else that
897 has been allocated in silc_server_init. The affected file
900 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
902 * Added functions silc_parse_version_string, silc_version_to_num,
903 and silc_ske_parse_version to parse SILC protocol style version
904 strings. Affected files lib/silcutil/silcutil.[ch] and
905 lib/silcske/silcske.[ch].
907 * Added new configuration params: version_protocol, version_software
908 and version_software_vendor to specify what version the remote
909 host must at least be to be able to connect to server. The vendor
910 string can be regex matched too. Added new function
911 silc_server_connection_allowed to check maximum number of allowed
912 connections, and allowed versions for incoming connections.
913 Affected files are silcd/server.c, server_util.[ch] and
916 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
918 * Added preliminary support for signals in scheduler. The
919 signals we care about are now blocked always when the scheduler
920 is locked. This way we can synchronise the use of signal with
921 scheduler. It is guaranteed that when signal occurs the scheduler
922 is not locked, and thus new tasks can be safely added to the
925 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
926 to silc_schedule_internal_init and silc_schedule_internal_uninit.
927 Added new platform specific routines
928 silc_schedule_internal_signals_[un]block and
929 silc_schedule_internal_signal_[un]register.
931 Added new functions to SILC Schedule API:
932 silc_schedule_signal_[un]register. Each signal that application
933 is going to use should be registered to the scheduler.
935 Affected files are lib/silcutil/silcschedule.[ch],
936 lib/silcutil/*/silc*schedule.c.
938 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
940 * Check for unauthenticated client and server in the
941 silc_server_new_client and silc_server_new_server functions.
942 Affected file silcd/packet_receive.c.
944 * Added function silc_string_is_ascii to check whether given
945 string is 7-bit ASCII string. Affected files are
946 lib/silcutil/silcutil.[ch].
948 * Added function silc_id_is_valid_server_id into the
949 silcd/serverid.c and added checking for valid Server ID's in
950 silc_server_new_server. The Server ID must always be based
951 on the server's public IP address.
953 * Added logging of DISCONNECT packet message in the server.
954 Affected file silcd/server.c.
956 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
958 * Changed all library interfaces that use Global RNG to also
959 accept SilcRng as argument. Affected files are
960 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
961 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
962 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
963 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
966 * Added function silc_pkcs_generate_key to the
967 lib/silccrypt/silcpkcs.[ch] for applications so that they
968 don't need to do pkcs->pkcs->init calls anymore.
970 * Remove SilcSocketConnection from the SFTP API since it really
971 wasn't needed there. The application has the information
972 saved in its contexts anyway and the SFTP layer doesn't need
973 know about it. Affected files lib/silcsft/silcsftp.h and
974 lib/silcsftp/sftp_[server/client].c.
976 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
977 The SilcSimContext is not SilcSim.
979 * Fixed possible buffer overflows in silc_id_render in the
980 lib/silcutil/silcutil.c.
982 * On EPOC the global crypto module lists are not used at all
983 in the crypto library. Added support for using the constant
984 algorithm list on EPOC. Affected files are
985 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
988 * Fixed the handling of third parameter of KICKED notify, since
989 it was mistakenly updated to SILC Protocol 1.0 even though it
990 is to be included in 1.1. Since it is not in 1.0 it is not
991 mandatory, and this fix now handles it only if it is provided,
992 and it is not error if it is not provided. Affected file
993 lib/silcclient/client_notify.c.
995 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
997 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
998 client. Affected file irssi/src/silc/core/client_ops.c.
1000 * Merged with Irssi 0.8.4 from irssi.org CVS.
1002 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1004 * Check for valid socket connection in client entries before
1005 sending any messages. Fixes a crash, but doesn't fix some
1006 other underlaying bug that is lurking there. Affected
1007 file silcd/packet_send.c.
1009 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
1011 * $usermode, $cumode and $cumode_space expandos shouldn't do
1012 anything with non-SILC server records. Affected file
1013 irssi/src/silc/core/silc-expandos.c
1015 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1017 * Fixed the silc_net_check_[host/local]_by_sock to support
1018 IPv6 bound sockets as well. Now they can return IPv6 addresses
1019 as well. Affected file lib/silcutil/silcnet.c.
1021 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
1022 Affected lib/silcutil/unix/silcunixnet.c.
1024 * Fixed ID rendering (at least on some platforms, not NetBSD)

1031 hash public keys and compare public keys in hash table. Affected
1032 file lib/silcutil/silcutil.[ch].
1034 * Added support for specifying multiple public keys for Client
1035 connection section in server configuration file. This makes it
1036 possible to accept multiple public keys from same host, or to
1037 make a section that accepts any incoming host, and have the
1038 accepted public keys listed in the section.
1040 Added functions silc_sever_[find/get]_public_key, added the
1041 support for this actually to all connection sections but only
1042 the Client section is currently allowed to specify multiple

1150 includes/silcincludes.h.
1152 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
1153 old name went against naming convention. Applications now
1154 include "silcclient.h" instead of "clientlibincludes.h".
1155 Removed includes/clientlibincludes.h, it is redundant now.
1157 * Renamed includes/version.h to silcversion.h.
1159 * Added really preliminary support for OS/2 into the util
1160 library. Only thread & mutex API is implemented, others

1195 * Added `user_count' to the SilcChannelEntry which now tells the
1196 number of users on the channel. The user count is now saved
1197 in normal server of global channels as well. Affected files
1198 silcd/server.c, idlist.h, packet_receive.c and command.c.
1200 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
1201 include file utility functions.

1217 the SKE interface a bit.
1219 * Fixed padding problem in PKCS#1. The padding was not actually
1220 random since the random number generator was used incorrectly.
1221 This security bug affects only when encrypting with PKCS#1, and
1222 it is not currently used at all in SILC. SILC only use signing
1223 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.

1286 Affected files irssi/src/silc/core/silc-core.c,
1287 irssi/src/fe-text/silc.c.
1289 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1291 * Added new configuration options and blocks:
1292 keepalive_secs, reconnect_count, reconnect_interval,
1293 reconnect_interval_max, reconnect_keep_trying and

1308 the connection configuration object from the SilcServerConnection
1309 object instead of finding it during the connecting phase.
1310 Added the configuration object to SilcServerConnection struct.
1311 Affected files silcd/server_internal.h, server.c.
1313 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1315 * Add the client on channel after it was resolved at the
1316 channel message receiving, and it was not already on the
1317 channel. Affected file lib/silcclient/client_channel.c.
1319 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1335 authentication to be set at the same time.
1337 Added `prefer_passphrase_auth' setting in config file which
1338 can be used to set to prefer passwd auth if both passwd and
1339 public key is set. If not set, public key is preferred.
1340 This has effect only when being initiator (responder will try
1343 Added support for authentication with passphrase and public key
1344 at the same time. The passphrase is tried first always since
1345 it is faster to check.
1347 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
1349 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

1395 * Fixed the file transfer's key agreement payload to include
1396 zero port also if the hostname is NULL because it could not
1399 Call file transfer monitor callback now also if error occurs
1400 during key agreement protocol.
1402 Changed the silc_client_file_send interface to return the
1403 SilcClientFileError instead of session id. The session ID
1404 is returned into pointer provided as argument.

1419 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
1420 SILC_LOG_WARNING to give out Warning and not Error. Affected
1421 file lib/silcutil/silclog.c.
1423 * Fixed the channel message payload decryption in the function
1424 silc_channel_message_payload_decrypt to not modify the original
1425 buffer before it is verified that the message decrypted
1426 correctly. Otherwise, next time it is called with correct
1427 channel key it won't encrypt since the payload is corrupted.
1428 Affected file lib/silccore/silcchannel.c.
1430 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1442 * Fixed a bug in hash table internal routine for traversing
1443 the table with foreach callback. The current entry may
1444 become invalid in the callback but it was referenced after
1445 the callback returned.
1447 Do not allow auto rehashing of hash table during the
1448 silc_hash_table_foreach operation, for same reasons as it is
1449 not allowed for SilcHashTableList. Affected files are
1450 lib/silcutil/silchashtable.[ch].
1452 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>

1473 users list to SilcHashTable. The affected files are
1474 lib/silcclient/idlist.[ch].
1476 * Fixed a bug in hash table tarversing. While the hash table
1477 is traversed with SilcHashTableList the table must not be
1478 rehashed. It is now guaranteed that auto rehashable tables
1479 are not rehashed while tarversing the list. Also defined that
1480 silc_hash_table_rehash must not be called while tarversing
1481 the table. Added function silc_hash_table_list_reset that must
1482 be called after the tarversing is over. The affected files are
1483 lib/silcutil/silchashtable.[ch].
1485 * Changed all hash table traversing to call the new
1486 silc_hash_table_list_reset in server and in client library.
1488 * Added function silc_client_on_channel to return the
1489 SilcChannelUser entry if the specified client entry is joined
1490 on the specified channel. This is exported to application as
1491 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
1493 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1496 server. The notify for mode change must be sent always and
1497 not only if !cmd->pending. Affected file silcd/command.c.
1499 * Fixed the WHOWAS command's reply sending to support the
1500 lists correctly. Affected file silcd/command.c.
1502 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1504 * When sending JOIN command to router for processing the
1505 sender's old command identifier was not saved back to the
1506 sender's command context, fixed now. The affected file is
1509 * Create the key in JOIN command of the router did not return
1510 the channel key, added check for this. Affected file is
1513 * Fixed a channel ID update bug in JOIN command reply. Do
1514 not directly upgrade the ID but call the function
1515 silc_idlist_replace_channel_id if the ID was changed.
1516 Affected file silcd/command_reply.c.
1518 * Fixed memory leaks from command calling if it would fail.
1519 Affected file silcd/command.c.

1531 * Removed TRQ from lib/trq, not needed anymore.
1533 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
1534 with server connections. Later this will be configurable
1535 in config file after new config file is done. Affected file
1538 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1540 * Fixed a crash in server related to channel announcements.
1541 Affected file silcd/server.c.

1545 * Fixed memory leaks in silc_server_create_new_channel*
1546 functions. Affected file silcd/server.c.
1548 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
1549 which ID was changed. This way the router will send the
1550 user list for the channel again, and server won't be in
1551 desync in some rare circumstances. Affected file is
1552 silcd/packet_receive.c.
1554 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1556 * Check for NULL socket pointer in the function
1557 silc_server_packet_send_to_channel_real. Affected file
1558 silcd/packet_send.c.
1560 * Fixed the BAN notify handling to correctly remove ban
1561 list. Affected file silcd/packet_receive.c.
1563 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1565 * Fixed some header addition to Toolkit distribution in
1566 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
1568 * Added lib/silcclient/client_ops_example.h as an template
1569 file for application programmers to quickly start using
1570 the SilcClientOperation functions in their application.
1571 Updated the lib/silcclient/README as well to tell about this
1572 nice file made available.
1574 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1576 * Call silc_server_remove_from_channels when removing client
1577 entry when NO_SUCH_CLIENT_ID was received. Affected file
1578 is silcd/command_reply.c.
1580 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1582 * Added server & router operator statistics updating. Affected
1583 file silcd/packet_receive.c and silcd/command.c.
1585 * Fixed the SERVER_SIGNOFF notify handling on normal server
1586 not to save the history information for clients. Same was
1587 fixed earlier in remove_clients_by_server function, but not
1588 here. Affected file silcd/packet_receive.c.
1590 * Raised the default connection-retry count from 4 to 7 in
1591 server. Affected file silcd/server.h.
1593 * Cancel any possible reconnect timeouts when we start the
1594 key exchange. Affected file silcd/server.c.
1596 * Do not reconnect on connection failure when SCONNECT was
1597 given. Affected files silcd/server.[ch].
1599 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1601 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
1603 * Fixed the NICK command to always give the unformatted
1604 nickname to the one giving the NICK command. If unformatted
1605 nickname is cached already it will be formatted and the
1606 local entry will always get the unformatted nickname.
1607 Affected file lib/silcclient/idlist.c.
1609 * Fixed some double frees from client library commands.
1610 Affected file is lib/silcclient/command.c.
1612 * Fixed CUMODE command in server to assure that no one can
1613 change founder's mode than the founder itself, there was a
1614 little bug. Affected file silcd/command.c.
1616 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1618 * Removed the SilcClientCommandDestructor from the client
1619 libary, it is not needed anymore. Affected files are
1620 lib/silcclient/silcapi.h, command[_reply].[ch],
1621 client_notify, idlist.c.
1623 * Fixed GETKEY command to first resolve client, and then
1624 resolve the server only if the client was not found, instead
1625 of resolving both at the same time. Affected file is
1626 lib/silcclient/command.c.
1628 * Added silc_client_start_key_exchange_cb and lookup the
1629 remote hostname and IP address before starting the key
1630 exchange with server. The affected file is
1631 lib/silcclient/client.c.
1633 * The server's public key is now saved using the IP address
1634 of the server and not the servername for the filename.
1635 The hostname public key filename is checked as an fall back
1636 method if the IP address based filename is not found.
1638 Fixed the GETKEY command to save the fetched server key
1639 in correct filename.
1641 Print the remote server's hostname now when new key is
1642 received during connection process. Affected file is
1643 irssi/src/silc/core/client_ops.c.
1645 * Return always our own public key to the client if it asks
1646 for it with GETKEY command. Affected file silcd/command.c.
1648 * Removed the use_auto_addr variable from default config
1649 file since it was in wrong section. Affected file is
1652 * Fixed TOPIC_CHANGE notification to not route it when it
1653 was sent using silc_server_send_notify_to_channel function.
1654 Affected file silcd/command.c.
1656 * Fixed silc_server_send_notify_kicked to send the kicker's
1657 Client ID also, it was missing. Affected files are
1658 silcd/command.c, silcd/packet_send.[ch].
1660 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1662 * Do not save client history information in SERVER_SIGNOFF.
1663 Fixes the bug in normal server that it does not detect
1664 the client becoming valid after the server becomes back
1665 online. Affected file silcd/server_util.c.
1667 * Added `sock_error' field into the SilcSocketConnection
1668 context. When error occurs during socket operation (read
1669 or write) the error is saved. Added also new function
1670 silc_socket_get_error to return human readable socket error
1671 message. Affected files are lib/silcutil/silcsockconn.[ch],
1672 lib/silcutil/unix/silcunixsockconn.c, and
1673 lib/silcutil/win32/silcwin32sockconn.c.
1675 * The server now prints the socket error message in the
1676 signoff for client. Affected file silcd/server.c.
1678 * Fixed the `created' channel information sending from router
1679 to server in JOIN command. Checks now whether the channel
1680 really was created or not and set it according that.
1682 Fixed the JOIN command to use the client entry's current
1683 ID during the joining procedure instead of the one it sent
1684 in the command (it is checked though), since it can change
1685 between the packet processing and command processing, and
1686 would just case unnecessary pain in the client end. Affected
1687 file silcd/command.c.
1689 * Fixed a channel key payload sending to use correct channel
1690 ID when the server was forced to change the channel's ID by
1691 router. Router sent the key payload with the old Channel ID.
1692 Affected file silcd/packet_receive.c.
1694 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1696 * Call silc_server_save_channel_key only if the key payload
1697 was provided in the JOIN command's command reply. Affected
1698 file silcd/command_reply.c.
1700 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1702 * Fixed silc_mp_sizeinbase to return the value correctly with
1703 MPI. Affected file lib/silcmath/mp_mpi.c.
1705 * Fixed the stop_server signal to correctly stop the scheduler
1706 and gracefully stop the server when SIGTERM or SIGINT signals
1707 are received. Affected file silcd/silcd.c.
1709 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1711 * Simple handling of TERM and HUP signals. Also added some log
1712 flushing call around. Affected file is
1715 * Fixed small bugs in silclog.c. Now buffering output will take
1716 effect after 10 seconds since startup: This will ensure that
1717 no important startup messages are lost. Also output redirection
1718 will preserve original format ([Date] [Type] message).
1719 Affected file is lib/silcutil/silclog.c.
1721 * Added two options to the config file, in the logging section:
1722 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1723 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1725 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1727 * Do not print the warning about log files not being initialized
1728 more than once to avoid excess logging. Affected file is
1729 lib/silcutil/silclog.c.
1731 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1732 the SIM copying in make install in Makefile.am.pre.
1734 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1736 * Rewritten silclog APIs. Globally interesting changes follows:
1737 silc_log_set_files() changed to silc_log_set_file().
1738 silc_log_set_callbacks() changed to silc_log_set_callback().
1739 ROBOdoc documented silclog header file.
1740 SilcLogCb now returns bool to wether inihibit the default
1741 handler or not (to keep the old behaviour return always TRUE).
1742 The new APIs should also fix the problem of the
1743 silcd_error.log file that was written in the current directory.
1746 Log files streams will remain opened after silc_log_set_file()
1747 call, means less CPU usage notably on high traffic servers.
1748 File streams are now full buffered, and flushed to the disk
1749 every 5 minutes, lesses HD activity and CPU usage.
1750 Messages can be redirected, allowing admins to configure
1751 one single logfile for all server messages.
1752 the silc_log_quick global variable to activate fast-logging.
1753 Affected files lib/silcutil/silclog.[ch]
1755 * Changed some code to conform new silclog APIs. Affected
1756 files are doc/example_silcd.conf.in, silcd/server.c
1757 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1760 * Fixed a memory leak that could occur in some situations.
1761 Affected file silcd/serverconfig.c.
1763 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1765 * Added the silc_client_del_client to remove the client from
1766 all channels as well. Affected file lib/silcclient/idlist.c.
1768 * Fixed the client library to correctly remove the client
1769 from all channels when the client entry is being destroyed.
1770 Affected file lib/silcclient/client_notify.c, command.c.
1772 * Added auto-nicking support to the client library. If the
1773 applicatio now sets client->nickname it will be sent to the
1774 server after connecting by the library. This way for example
1775 SILCNICK (or IRCNICK) environment variables will have effect
1776 and always change the nickname automatically to whatever
1777 it is wanted. Affected file lib/silcclient/client.[ch].
1779 * Renamed silc_server_command_bad_chars to the
1780 silc_server_name_bad_chars and moved it to the
1781 silcd/server_util.[ch]. Added also new function
1782 silc_server_name_modify_bad to return nickname that
1783 includes bad characters as new nickname without those
1784 bad characters. This check and modify is now used in
1785 silc_server_new_client when the username is initially set
1786 as nickname, so it must be checked to be valid nickname.
1787 Affected file silcd/packet_receive.c.
1789 * The nickname length is now taken from the packet for real
1790 and not trusted to strlen() since it clearly can return
1791 wrong length for nickname including bad characters. This
1792 also applies to channel names. Affected file silcd/command.c.
1794 * Removed the lib/silcsilm/modules directory. Modules are now
1795 compiled into the lib/silcsim. Fixed the copying of the
1796 modules to follow symbolic links in Makefile.am.pre.
1798 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1800 * Fixed silc_string_regexify list creation. Fixes bugs with
1801 BAN and INVITE commands in server. The affected file is
1802 lib/silcutil/unix/silcunixutil.c.
1804 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1806 * Removed the command destructor entirely from the server's
1807 command and command reply routines. It is not needed, and
1808 its usage was buggy and caused crashes. Affected files are
1809 silcd/command[_reply].[ch].
1811 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1813 * Cancel protocol and NULL sock->protocol if timeout
1814 occurred during protocol. Affected file silcd/server.c.
1816 * Cancel protocol timeouts always before calling the final
1817 callback, to assure that after final callback is called
1818 no other state will be called for the protocol anymore.
1819 Affected file silcd/protocol.c.
1821 * Print error log if incoming connection configuration could
1822 not be found. Affected file silcd/server.c.
1824 * Fixed JOIN command to correctly save the founder mode
1825 to the client on normal SILC server, when the channel
1826 was created by the router. Affected file silcd/command.c.
1828 * Fixed LIST command (hopefully) to send correct reply
1829 packets. Affected file silcd/command.c.
1831 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1833 * The silc_packet_receive_process now returns FALSE if the
1834 read data was invalid packet, and TRUE if it was ok.
1836 The server now checks that if unauthenticated connection
1837 sends data and its processing fails the server will close
1838 the connection since it could be a malicious flooder.
1840 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1842 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1844 * Make sure the warning about error opening a log file is
1845 printed only once and not everytime it fails (produces
1846 too much useless log). Affected file lib/silcutil/silclog.c.
1848 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1850 * Made the silc_server_daemonise() function more readable.
1851 Affected file silcd/server.c.
1853 * Pid file is now optional, the user may comment it out from
1854 the config file. Removed define SILC_SERVER_PID_FILE, we
1855 don't need a default any longer. Affected file
1856 configure.in.pre, lib/Makefile.am.pre.
1858 * Make some use of the pid file. The server now dies at startup
1859 if it detects a valid pid file on his path. The server would
1860 die anyway in this circumstance, because of the bind() failure.
1861 Affected file silcd/silcd.c.
1863 * No longer compiling lib/dotconf.
1865 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1867 * Fixed JOIN command parsing not to crash. Affected file
1868 lib/silcclient/command.c.
1870 * Fied the NICK_CHANGE notify to add the new client entry
1871 even it is resolved. This removes an <[unknown]> nick
1872 thingy bug in the client. Affected file is
1873 lib/silcclient/client_notify.c.
1875 * Do not try to allocate 0 bytes (efence does not like it)
1876 in lib/silccore/silccomand.c when encoding payload.
1878 * Do not take IRCNICK as nickname in Irssi SILC client since
1879 it is not possible to set nickname before hand connecting
1880 the server (TODO has an entry about adding auto-nicking
1883 * Changed the silc_server_command_pending to check whether
1884 there already exists an pending entry with the specified
1885 command, command identifier and pending callback. This is
1886 to fix IDENTIFY and WHOIS related crashes that may register
1887 multiple pending commands with same identifier. Affected
1888 file silcd/command.c.
1890 * Fixed the server to reconnect to the router even if it
1891 was already reconnecting and EOF was received. This to
1892 fix a possibility that the server wouldn't ever try to
1893 auto-reconnect to the router. Affected file silcd/server.c.
1895 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1897 * Fixed the server's password authentication to use the
1898 length of the locally saved password, and not the one
1899 sent in the packet. Affected file silcd/protocol.c.
1901 * Fixed same password authentication problem in the
1902 Authentication Payload handling routines in
1903 lib/silccore/silcauth.c.
1905 * Yet another password authentication problem fixed with
1906 channel password handling in silcd/command.c.
1908 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1910 * If first character of string in silc_parse_userfqdn is '@'
1911 then do not parse it. Affected file is
1912 lib/silcutil/silcutil.c.
1914 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1916 * Fixed minor bug in IDENTIFY command reply sending, which
1917 caused various weird problems during JOIN when it was
1918 resolving names for users. Affected file silcd/command.c.
1920 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1922 * Fixed the IDENTIFY command reply sending to chech better valid
1923 clients. It was possible to send incomplete list of replies.
1924 Affected file silcd/command.c.
1926 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1928 * Added silc_client_command[s]_[un]register functions now to
1929 dynamically register the commands in client library. Removed
1930 the static table of commands. This allows the client library
1931 to call commands without causing the application to know about
1932 what commands library has called.
1934 Removed the INFO command reply kludge to detect when the command
1935 was called by library. Now library use its own command reply
1936 function for INFO command.
1938 Added function silc_client_command_call to call a command.
1939 Application can use it to call command, not access the structure
1942 Now all commands that are sent by the client library (not
1943 explicitly sent by application) use own command reply functions.
1945 Affected files around lib/silcclient/ and in
1946 irssi/src/silc/core/.
1948 * Fixed the WHOIS command reply sending to chech better valid
1949 clients. It was possible to send incomplete list of replies.
1951 Fixed the WHOIS and IDENTIFY to send the request to router
1952 if normal server did not do it and did not find any results.
1954 Affected file silcd/command.c.
1956 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1958 * Moved the internal data from SilcClient context into its
1959 own file, not accesible to application. Affected files
1960 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1961 and other files in client library.
1963 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1965 * Added doc/examples installation target in Makefile.am.pre.
1968 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1970 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1971 commands the found client entry will be removed from the
1972 cache, after notifying application about the error. Affected
1973 file lib/silcclient/command_reply.c.
1975 * Changed the /MSG to check for exact nickname user gave, and
1976 not let `nick' match `nick@host' if it is only one found. Now,
1977 user must type the exact nickname (like nick@host2) even if
1978 there are no more than one same nicks found. This is to avoid
1979 a possibility of sending nickname to wrong nickname since
1980 `nick' could match `nick@host'. Affected file is
1981 irssi/src/core/silc-servers.c.
1983 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1985 * Do not print "you are now server operator" or similar when
1986 giving /away command. Affected files are
1987 irssi/src/silc/core/client_ops.c, silc-servers.h.
1989 * Made the silc_server_command_pending_error_check to send
1990 the same command reply payload it received back to the
1991 original sender of the command. This way all arguments
1992 that was received by the server will be received by the
1993 client too. Affected file silcd/command.c.
1995 * Added the silc_idcache_add to return the created cache entry
1996 to a pointer. Affected file lib/silccore/silcidcache.[ch].
1998 * Add global clients to expire if they are not on any channel.
1999 This is because normal server will never know if they signoff
2000 if they are not on any channel. The cache expiry will take
2001 case of these entries. This is done by normal servers only.
2002 The affected files are silcd/command_reply.c,
2003 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
2005 * If server receives invalid ID notification for WHOIS or
2006 IDENTIFY and the ID exists in the lists, it is removed.
2007 Affected file silcd/command_reply.c.
2009 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
2010 in client then client entry that it matches is searched and
2011 the nickname is printed on the screen for user. Affected
2012 file irssi/src/silc/core/client_ops.c.
2014 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2016 * Use cache entry expire time in the LIST command reply to
2017 purge old entries from the cache after the LIST command
2018 reply has been received. This way we don't have non-existent
2019 entries in the cache for too long. Affected file is
2020 silcd/command_reply.c.
2022 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2024 * If we are normal server, and we've not resolved client info
2025 in WHOIS or IDENTIFY from router, and it is global client,
2026 we'll check whether it is on some channel. If it is not
2027 then we cannot be sure about its validity and will resolve it
2028 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
2029 file silcd/command.c.
2031 * Search channel by name (if possible) rather than by ID
2032 in IDENTIFY command's command reply. Affected file is
2033 silcd/command_reply.c.
2035 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2037 * Distribute to the channel passphrase in CMODE_CHANGE notify.
2038 Updated specs and implemented it. Affected file silcd/command.c,
2039 silcd/packet_send.c and silcd/packet_receive.c.
2041 * Implemented the <founder auth> payload handling in the JOIN
2042 command. If provided all conditions for channel joining
2043 except requirement to provide correct passphrase can be
2044 overrided by the channel founder. Updated the protocol specs.
2045 Affected file silcd/command.c.
2047 Added support for founder auth in JOIN command in client
2048 library. Fixed the parsing of the JOIN command now to support
2049 all options as they should be. The affected file is
2050 lib/silcclient/command.c.
2052 * Optimized the WHOIS and IDENTIFY commands to send the request
2053 to router only if it includes nicknames or other names. If
2054 they include only IDs then check the local cache first before
2055 routing. Affected file is silcd/command.c.
2057 * Added channels topic announcements. Affected file is
2058 silcd/packet_receive.c and silcd/server.c.
2060 * Fixed the silc_server_send_notify_topic_set to really destine
2061 the packet to channel. Affected file silcd/packet_send.c.
2063 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
2064 library. Affected file lib/silcclient/client_notify.c.
2066 * Added UMODE announcements. Affected file silcd/server.c.
2068 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2070 * Memory leak fixes in:
2072 lib/silcutil/silcsockconn.c
2073 lib/silcske/silcske.c
2074 lib/silcske/groups.c
2076 lib/silccrypt/silcpkcs.c
2077 lib/silccore/silccommand.c

2083 * ROBOdoc documented the lib/silcske/groups.h file and a
2084 bit changed the interface for better.
2086 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2088 * Update the client entry context in the ID cache after
2089 nick change. Affected file lib/silcclient/command.c.
2090 Fixes the CUMODE command when regaining founder privileges,
2091 and a little WHOIS problem.
2093 * Fixed silc_net_gethostbyname to correctly call the
2094 inet_ntop. Affected file lib/silcutil/silcnet.c.
2096 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2098 * Added IPv6 support checking to the configure.in.pre, added
2099 also --enable-ipv6 option to override the check. Affected
2100 file configure.in.pre.
2102 * The silc_thread_create now calls the start function
2103 directly if threads support is not compiled in. Removes
2104 ugly #ifdef's from generic code. Affected files are
2105 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
2107 * Added silc_net_gethostby[name/addr]_async to asynchronously
2108 resolve. Affected files are lib/silcutil/silcnet.[ch].

2126 * Fixed LIST command reply sending in server. Affected file
2129 * Server now sends the kicker's client ID in the KICK notify
2130 to the kicked client. Affected file silcd/command.c.
2132 * The client library now parses the kickers client ID and
2133 UI displays it. Affected files lib/silcclient/client_notify.c
2134 and irssi/src/silc/core/silc-channels.c, module-formats.c.
2136 * Made all payload parsing function prototypes consistent.
2137 They all take now const unsigned char * and uint32 pair as
2138 the payload data instead of SilcBuffer. Changes all around
2139 the source tree. Other unsigned char* -> const unsigned char*
2140 changes around the tree as well.
2142 * Optimized SFTP client and server packet sending not to
2143 allocate new buffer for each packet but to recycle the
2144 first allocated buffer. Affected files are
2145 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
2147 * Optimized the SFTP client to use SilcList instead of
2148 SilcDList for requests, because it is faster. Affected file
2149 is lib/silcsftp/sftp_client.c.
2151 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
2152 into lib/silccore/silcid.[ch].
2154 Renamed silcpayload.[ch] into silcargument.[ch].
2156 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2158 * If client entry is deleted with active key agreement
2159 session, abort the session.
2161 The silc_client_abort_key_agreement now calls the completion
2162 callback with new SILC_KEY_AGREEMENT_ABORTED status.
2164 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
2167 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2169 * Don't use __restrict in older GCC's. Affected file is
2170 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
2172 * silc_net_localhost now attempts to reverse lookup the
2173 IP/hostname. Affected file lib/silcutil/silcnet.c.
2175 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
2176 command. It can be used to gain founder privileges at
2177 the same time when joining the channel.
2179 Defined that the SILC_NOTIFY_TYPE_KICKED send the
2180 kicker's client ID as well. Updated protocol specs.
2182 Defined that the server must send SILC_COMMAND_IDENTIFY
2183 command reply with error status to client who sent
2184 private message with invalid client ID.
2186 Updated the protocol specification.
2188 * Added silc_server_send_command_reply to send any
2189 command reply. Affected file silcd/packet_send.[ch].
2191 * Added silc_id_payload_encode_data to encode ID payload
2192 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
2194 * The server now send IDENTIFY command reply with error
2195 status if client ID in private message is invalid. Affected
2196 file silcd/packet_receive.c.
2198 * Save the server key file with server's IP address in
2199 the filename instead of hostname. The affected file is
2200 irssi/src/silc/core/client_ops.c.
2202 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2204 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
2207 * Added libtool support for compiling shared objects in
2208 lib/silcsim. Affected file configure.in.pre and
2209 lib/silcsim/Makefile.am. Original patch by cras.
2211 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2213 * Pid file configuration, and server's config file fixes
2214 patch by toma. Updated CREDITS file.
2216 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2218 * Fixed silc_client_channel_message to not try to decrypt
2219 the message twice if it resolved the destination client
2220 information. This could cause of dropping one channel
2221 message. Affected file lib/silcclient/client_channel.c.
2223 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2225 * Added silc_client_run_one into lib/silcclient/silcapi.h and
2226 lib/silcclient/client.c. This function is used when the SILC
2227 Client is run under some other scheduler, or event loop or
2228 main loop. On GUI applications, for example this may be
2229 desired to used to run the client under the GUI application's
2230 main loop. Typically the GUI application would register an
2231 idle task that calls this function multiple times in a second
2232 to quickly process the SILC specific data.
2234 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2236 * Fixed silc_server_drop() for dropping the supplementary
2237 groups as well, this could cause a security hole on some
2240 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2242 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
2245 * Write PID file after dropping privileges. Added -F option
2246 to run server on foreground. A patch by debolaz.
2247 Affected files silcd/server.c, silcd/silcd.c.
2249 * Fixed MOTD to return the MOTD file server name. Affected
2250 file silcd/command.c.
2252 * Added INFO command reply handling to the Irssi SILC Client.
2253 Affected file irssi/src/silc/core/client_ops.c.
2255 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2257 * Fixed the silc_idcache_list_* routines to really support
2258 the dynamic list. Fixes a crash. Affected file is
2259 lib/silccore/silcidcache.c.
2261 * Fixed the LIST command reply to really call LIST command's
2262 pending callbacks. Affected file silcd/command_reply.c.
2264 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2266 * Update conn->local_entry->nickname after giving NICK
2267 command. Affected file lib/silcclient/command.c.
2269 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
2271 * Added the [pid] option to the silcd configuration file
2273 Affected files: serverconfig.[ch] and silcd.c
2275 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2277 * Save fingerprint in WHOIS command reply in server.
2278 Affected file silcd/command_reply.c.
2280 * Fixed NICK commands pending callback registration.
2281 Affected file lib/silcclient/command.c.
2283 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2285 * Use ++server->cmd_ident when sending commands in server,
2286 instead of random number. Affected file silcd/command.c.
2288 * Fixed GETKEY command reply to call actually GETKEY pending
2289 command callbacks. Affected file silcd/command_reply.c.
2291 * A bit stricter check for nicknames. Check for same nickname
2292 in NICK command also. Affected file silcd/command.c.
2294 * Do not call INFO command everytime client ID changes, only
2295 during first connecting. Affected file lib/silcclient/client.c.
2297 * Set the new nickname only after successful command reply for
2298 NICK command is returned by server. Affected file
2299 lib/silcclient/command.c.
2301 * Remove nicknames from nicklist during server_signoff notify.
2302 Should fix /NAMES bit more. The affected file is
2303 irssi/src/silc/core/silc-channels.c.
2305 * Added `fingerprint' field to the SilcIDListData in the
2306 silcd/idlist.h to hold the fingerprint of the client's
2309 Send the fingerprint of the client's public key in WHOIS
2312 Affected files silcd/command.c, and silcd/idlist.[ch].
2314 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
2315 create fingerprint from given data.
2317 * Show the fingerprint of the client's public key in WHOIS.
2318 Affected files irssi/src/module-formats.[ch] and
2319 irssi/src/silc/core/client_ops.c.
2321 * Format the multiple same nicknames also during JOIN and
2322 NICK_CHANGE notifys. Affected file is
2323 lib/silcclient/client_notify.c.
2325 * Do not print error on screen for invalid private message
2326 payload since it can come if someone is sending private
2327 messages with wrong key. Affected file
2328 lib/silccore/silcprivate.c.
2330 * Fixed multiple concurrent /PING crash. Affected file
2331 lib/silcclient/command.c.
2333 * Changed the wrong ID encoding. All IP addresses must be
2334 in MSB first order in encoded format. They were encoded
2335 wrong and was in LSB format. Affected files are
2336 silcd/serverid.c, lib/silcutil/silcutil.c.
2338 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
2340 * Call the `connect' client operation through the scheduler
2341 in case of error. Affected file lib/silcclient/client.c.
2343 * Call the `failure' client operation even if the error
2344 occurred locally during a protocol. Affected file is
2345 lib/silcclient/protocol.c.
2347 * Added support of sending LIST command to router from normal
2348 server. This way normal server can get list of all channels
2349 in the network too. Fixed the channel list sending in the
2350 server too. Affected files are silcd/command.c, and
2351 silcd/command_reply.[ch].
2353 * Added silc_server_update_channels_by_server and
2354 silc_server_remove_channels_by_server. They are used during
2355 disconnection of primary router and in backup router protocol.
2356 Affected file silcd/server_util.[ch], silcd/server.c and
2357 silcd/server_backup.c.
2359 * Fixed channel adding to global list in IDENTIFY command
2360 reply in server. Affected file silcd/command_reply.c.
2362 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2364 * If the incoming packet type is REKEY or REKEY_DONE process
2365 that packet always synchronously. Fixes yet another MAC
2366 failed error on slow (dialup) connections. Affected file
2367 lib/silcclient/client.c and silcd/server.c.
2369 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2371 * Call check_version SKE callback for initiator too. Affected
2372 file lib/silcske/silcske.c.
2374 * Implemented fix for security hole found in the SKE that was
2375 fixed in the specification few days back; the initiator's
2376 public key is now added to the HASH value computation.
2377 Added backwards support for the old way of doing it too, for
2378 old clients and old servers. Affected file is
2379 lib/silcske/silcske.c.
2381 * Enabled mutual authentication by default in SKE. If initiator
2382 is not providing mutual authentication the responder will
2383 force it. This will provide the proof of posession of the
2384 private key for responder. The affected files are
2385 lib/silcclient/protocol.c and silcd/protocol.c.
2387 * Do not cache anymore the server's public key during SKE.
2388 We do mutual authentication so the proof of posession of
2389 private key is done, and if the server is authenticated in
2390 conn auth protocol with public key we must have the public
2391 key already. Affected file silcd/protocol.c.
2393 * Added new global debug variable: silc_debug_hexdump. If
2394 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
2395 file lib/silcutil/silclog.[ch].
2397 * Fixed compilation warning due to char * -> const char *.
2398 Affected files lib/silcutil/silcnet.h, and
2399 lib/silccore/silcauth.[ch].
2401 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2403 * Fixed CMODE command when new channel key was created. If
2404 the creation failed the old key was removed. Next time giving
2405 same command would crash the server since the old key was
2406 freed already. Affected file silcd/command.c.
2408 * Fixed the silc_server_announce_get_channels to not crash
2409 on reconnect. Affected file silcd/server.c.
2411 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2413 * Added silc_log_set_debug_string function to set a regex
2414 string to match for debug output. Only the function names,
2415 or filenames matching the given debug string is actually
2416 printed. This way it is possible to filter out those debug
2417 strings that user is not interested in.
2419 Fixed a bug in silc_string_regexify.
2421 Affected files lib/silcutil/silclog.[ch], and
2422 lib/silcutil/unix/silcunixutil.c.
2424 * Changed the -d options in both server and Irssi SILC client
2425 to take the debug string as argument. Affected files
2426 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
2428 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2430 * Added silc_hash_babbleprint to create a Bubble Babble
2431 Encoded fingerprint. The encoding is developed by Antti
2432 Huima (draft-huima-babble-01.txt), and it creates human
2433 readable strings out of binary data. Affected file
2434 lib/silccrypt/silchash.[ch].
2436 * Print the babble print now in addition of fingerprint as well
2437 in Irssi SILC client. Affected files are
2438 irssi/src/fe-common/silc/module-formats.[ch],
2439 irssi/src/fe-common/silc/core/client_ops.c.
2441 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2443 * Fixed a security problem found in SKE. The initiator's
2444 public key too is now added to the HASH hash value creation
2445 which is signed by the responder to create the SIGN value.
2446 This will prevent anyone in the middle to lie to the responder
2447 about the initiator's public key. If this is done now, the
2448 man in the middle will get caught. Updated the protocol
2451 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2453 * Better installation directory handling. Configure module
2454 paths and other paths automatically to example_silc* files
2455 in doc/. A patch by toma.
2457 * Fixed compiler warning from MPI library, and from SILC RNG.
2460 * Added SILC_SERVER_PID_FILE to define the pid file for server.
2461 It can be configured with ./configure. A patch by toma.
2463 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2465 * Find correct make to use in prepare-clean. A patch by
2466 toma. Affected file prepare-clean.
2468 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
2470 * Added irssi variables use_auto_addr, auto_bind_ip,
2471 auto_bind_port and auto_public_ip.
2473 * Changed the interface for silc_client_send_key_agreement
2474 in lib/silcclient/silcapi.h
2478 irssi/src/silc/core/silc-core.c
2480 lib/silcclient/silcapi.h
2481 irssi/src/silc/core/silc-channels.c
2482 lib/silcclient/client_keyagr.c
2485 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2487 * Added silc_pkcs_public_key_compare to compare two
2488 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
2490 * Check that the client who set the founder mode on the
2491 channel is the same client that is giving the founder
2492 mode to itself. It is done by comparing the saved public
2493 key (it is saved even in the authentication is passphrase).
2494 Affected file silcd/command.c.
2496 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2498 * Do not process packet for disconnected socket connection.
2499 Affected file lib/silccore/silcpacket.c.
2501 * Process the DISCONNECT packet through scheduler in the
2502 client library. Affected file lib/silcclient/client.c.
2504 * Fixed the silc_client_packet_parse to not to increase
2505 the packet sequence number if the conn->sock and the
2506 current socket connection is not same. This can happen
2507 for example during key agreement when the conn includes
2508 multiple socket connections (listeners). Affected file
2509 lib/silcclient/client.c.
2511 * The sender of the file transfer request now provides also
2512 the pointer (listener) for the key exchange protocol. If
2513 the listener cannot be created then it sends empty key
2514 agreement and lets the receiver provide the listener.
2516 Added `local_ip' and `local_port' arguments to the
2517 silc_client_file_send. If they are provided they are used,
2518 if not then it will attempt to find local IP address, if
2519 not found or bind fails then the remote client will provide
2522 Affected files are lib/silcclient/client_ftp.c and
2523 lib/silcclient/silcapi.h.
2525 * Extended the FILE SEND command to support defining the
2526 local IP and port for key exchange listener. They are
2527 optional. Affected file irssi/src/silc/core/silc-servers.c.
2529 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2531 * Defined to WHOIS command reply the sending of fingerprint
2532 of the client's public key (if the proof of posession of the
2533 corresponding private key is verified by the server).
2534 Updated to the protocol specification.
2536 * Added support of receiving the client's public key's
2537 fingerprint in command reply in client library. Affected
2538 file is lib/silcclient/command_reply.c, and
2539 lib/silcclient/idlist.[ch].
2541 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2543 * Do not send over 128 chars long nickname to the server
2544 in NICK command. Affected file lib/silcclient/command.c.
2546 * Do not send over 256 chars long channel names to the server
2547 in JOIN command. Affected file lib/silcclient/command.c.
2549 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2551 * Assure that silc_server_close_connection cannot be called
2552 twice for same socket context. Affected file is
2555 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2557 * Send error message to application if opening file for
2558 writing during file transfer fails. Affected file is
2559 lib/silcclient/client_ftp.c.
2561 Remove all file transfer sessions for a client that we're
2562 removing from ID cache.
2564 Affected file is lib/silcclient/client_ftp.c.
2566 * Fixed silc_net_addr2bin to return correct address. Affected
2567 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2569 * Fixed file transfer session removing on signoff notify.
2570 Affected file irssi/src/silc/core/silc-servers.c.
2572 * Added the SilcClientFileError to be returned in the monitor
2573 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
2574 Affected file lib/silcclient/silcapi.h.
2576 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2578 * Fixed a crash in silc_client_ftp_free_sessions and
2579 silc_client_ftp_session_free_client. Affected file
2580 lib/silcclient/client_ftp.c.
2582 * Added `disabled' field in the SilcChannelEntry in the server
2583 to indicate if the server entry is disabled. Affected file
2584 silcd/idlist.h, silcd/command[_reply].c.
2586 * SILC server adds now /var/run/silcd.pid everytime it is
2587 started. Affected file silcd/silcd.c.
2589 * Added silc_server_packet_send_clients to send a packet to
2590 the provided table of client entries. Affected file
2591 silcd/packet_send.[ch].
2593 * Fixed a crash in client resolving in client_prvmsg.c in
2594 client library. Affected file lib/silcclient/client_prvmsg.c.
2596 * Do not actually remove the client directly from ID cache
2597 during SERVER_SIGNOFF, but invalidate it. This way we
2598 preserve the WHOWAS info for the client. Affected file
2599 silcd/server_util.c.
2601 * Fixed SERVER_SIGNOFF notify handling in the server. The
2602 server is now able to process incoming SERVER_SIGNOFF notify
2603 for a server that it doesn't even know about. It will remove
2604 the clients provided in the notify. Affected file
2605 silcd/packet_receive.c.
2607 * Check for partial packet in data queue after every packet that
2608 was found from the queue. Return and wait for more data if
2609 there is partial data in queue. Affected file is
2610 lib/silccore/silcpacket.c.
2612 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2614 * Added SilcClietFileError enum to indicate error in

2627 irssi/src/fe-common/silc/module-formats.[ch].
2629 * Wrote a help file for FILE command.
2631 * Added silc_rng_global_get_byte_fast to get not-so-secure
2632 random data as fast as possible. Random data is read from
2633 /dev/urandom if available and from the SILC RNG if not
2634 available. It is used in padding generation. Affected file
2635 lib/silccrypt/silcrng.[ch].
2637 * All packets in client library are now processed synchronously.

2650 * Assure that silc_client_notify_by_server_resolve does not
2651 resolve the client information multiple times. If it cannot
2652 be found by the first it cannot be found at all. Affected
2653 file lib/silcclient/client_notify.c.
2655 * Fixed WHOWAS command reply calling. Affected file
2656 lib/silcclient/command_reply.c.
2658 * Removed all references to silc_idlist_get_client from the
2659 Irssi SILC client since that call is internal call used by
2660 the library. The Irssi SILC client will use now client
2661 retrieval functions found in silcapi.h.
2663 * Fixed a bug in resolving nickname info before sending
2664 private message. It used freed memory. Affected file
2665 irssi/src/silc/core/silc-servers.c.

2686 * Added silc_net_localip to return local host's IP address.
2687 Affected file lib/silcutil/silcnet.[ch].
2689 * If key exchange or rekey protocol is active for a connection
2690 parse all packets syncronously since there might be packets
2691 in packet queue that we are not able to process without first
2692 processing packets before them. Affected file silcd/server,
2693 lib/silcclient/client.c.
2695 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2696 whether library should continue processing the packet.
2697 Affected file lib/silccore/silcpacket.h.

2743 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
2744 is incomplete and is being resolved, it won't be resolved
2747 Make sure also that USERS command reply does not resolve
2748 twice information. Affected file is
2749 lib/silcclient/command_reply.c.
2751 Make sure that silc_client_get_clients_by_list does not
2752 resolve twice same information.
2754 * Check for valid client->id in the silc_server_free_client_data.
2755 Affected file silcd/server.c.
2757 * Fixed /GETKEY nick@server not to crash if the server entry
2758 is not found. Affected file lib/silcclient/command.c.

2768 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2770 * Call the silc_server_udpate_servers_by_server in the
2771 primary router that comes back online in the backup resuming
2772 protocol. Otherwise it routes packets wrong. Affected file
2773 silcd/server_util.[ch], silcd/server_backup.c.
2775 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2777 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2778 lib/silcutil/silcbuffmt.[ch].
2780 * Redefined the SILC packet header to include the padding
2781 length. Affected file lib/silccore/silcpacket.[ch].
2783 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2784 length for maximum padding up to 128 bytes). Affected
2785 file lib/silccore/silcpacket.h.
2787 * Removed all backwards support for old 0.5.x MAC thingies.
2788 The SILC packet header change makes it impossible to be
2789 backwards compatible.
2791 * Send the ENDING packet with timeout in the backup resuming
2792 protocol. This is to assure that all routers has connected
2793 to the primary router. Affected file silcd/server_backup.c.
2795 * Changed the RNG to take the first IV from random data. It
2796 used to take it from zero actually. Changed the RNG also
2797 to use /dev/urandom during session. /dev/random is used
2798 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2800 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2802 * Changed the SILC packet header to have the first two bytes
2803 (the packet length) encrypted. Affected files aroung the
2804 code tree, lib/silccore/silcpacket.[ch]. Removed the
2805 SilcPacketCheckDecrypt callback. It is not needed anymore
2806 since the silc_packet_receive_process will determine now
2807 whether the packet is normal or special.
2809 * Implemented the unidirectional MAC keys. Affected files
2810 lib/silcske/silcske.c, silcd/protocol.c and
2811 lib/silcclient/protocol.c.
2813 * Implemented the packet sequence number to the MAC computation.
2814 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
2815 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
2816 lib/silcclient/protocol.c.
2818 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2820 * Allow backup router to announce servers. All servers
2821 announced by backup router are added to the global list
2822 automatically. Update hte server's socket to our primary
2823 router also when backup router announces a server.
2824 Affected file silcd/packet_receive.c.
2826 * Do not update the client->router in the function
2827 silc_server_udpate_clients_by_server if the client is on
2828 global list. We might fail to find any specific server
2829 for locally connected clients and local cell clients. They
2830 should still use the `from' and not `to' as client->router.
2831 This fixes backup router resuming protocol. Affected file
2832 silcd/server_util.c.
2834 * Decrease channel statistics count only if the channel
2835 deletion worked. Affected files are silcd/server.c and
2836 silcd/server_util.c.
2838 * Added silc_server_update_servers_by_server to update origin
2839 of all server entries. Used during backup router protocol.
2840 Affected files silcd/server_util.[ch], silcd/server.c. and
2841 silcd/backup_router.c.
2843 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
2844 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
2845 silc_hmac_get_hash and silc_hmac_get_name. Affected file
2846 lib/silccrypt/silchmac.c.
2848 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2850 * Assure that router cannot reroute the same channel message
2851 to the sender. Affected file silcd/packet_receive.c.
2853 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2855 * Made better checks that the channel message is not sent
2856 to the router it came from. Affected file is
2857 silcd/packet_send.c. Fixed memory leak too.
2859 * Announce informations for incoming router connection, but
2860 only after checking if it is replaced by backup router.
2861 Affected file silcd/packet_receive.c.
2863 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2865 * Fixed the backup resuming protocol to work in multiple
2866 router environment. Affected file silcd/server_backup.c.
2868 * Route packet only to one router in the function
2869 silc_server_packet_send_to_channel. Affected file is
2870 silcd/packet_send.c.
2872 * Fixed silc_server_send_notify_dest to set the broadcast
2873 flag. Fixed the silc_server_send_notify_topic to actually
2874 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2875 Affected file silcd/packet_send.c.
2877 * Changed the SFTP Filesystem interface. Changed the
2878 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2879 the filesystem operation function. The SilcSFTPFilesystem
2880 is now a context that is allocated by all filesystem allocation
2881 functions and it already includes the operations structure
2882 and filesystem specific context. It is given as argument
2883 now to the silc_sftp_server_start. This made the interface
2884 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2885 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2887 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2889 * Changed the backup router adding and getting interfaces
2890 in the server. The router that will be replaced by the
2891 specified backup router is now sent as argument. Affected
2892 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2895 * Added silc_net_addr2bin_ne to return the binary form of
2896 the IP address in network byte order. Affected files
2897 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
2899 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2901 * Check for existing server ID in silc_server_new_server
2902 and in silc_server_connect_to_router_final and remove the
2903 old entry if it exists. Affected file silcd/packet_receive.c,
2906 * Send the channel message always to only one router, either
2907 in upstream or downstream. Affected file is
2908 silcd/packet_send.c.
2910 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

2913 protocol specification.
2915 * Removed one redundant channel key generation from normal
2916 server during joining procedure. Removed one redundant
2917 channel key sending from server to router during joining
2918 procedure. Affected file silcd/command.c.
2920 * Made minor bugfixes to the backup router resuming protocol.
2921 Affected file silcd/server_backup.c, server.c.

2930 resume the primary router position in the cell after the
2931 primary router comes back online. Affected files
2932 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
2933 and silcd/server_util.[ch].
2935 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2937 * Sleep two (2) seconds after sending QUIT command to server.
2938 Affected file lib/silcclient/command.c.
2940 * Assure that if outgoing data buffer is pending do not force
2941 send any data. Affected file silcd/packet_send.c.
2943 * Assure that if outgoing data buffer is pending do not force
2944 send any data. Affected file lib/silcclient/client.c.
2946 * Implemented the backup router support when the primary router
2947 goes down. The servers and routers can now use the backup
2948 router as new primary router without loosing connectivity.
2950 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2952 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
2953 in the server to indicate disabled entry. All data read
2954 from the connection will be ignored and no data is sent
2955 for entry that is disabled. Affected files are
2956 silcd/idlist.h, silcd/server.c.
2958 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2960 * Created SFTP client and server test programs in the
2961 lib/silcsftp/tests directory.
2963 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2965 * Implemented memory filesystem (virtual filesystem) for
2966 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
2969 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2971 * Implemented the SFTP (SSH File Transfer Protocol) to the
2972 lib/silcsftp. It includes SFTP client and SFTP server
2975 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2977 * Moved lib/silccore/silcprotocol.[ch] to the
2978 lib/silcutil library.
2980 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
2981 take variable argument list pointer as argument. Affected
2982 file lib/silcutil/silcbuffmt.[ch].
2984 * Added silc_buffer_set function that is used to set data
2985 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
2986 Affected file lib/silcutil/silcbuffer.h.
2988 * Changed various routines in the core library to use the new
2989 silc_buffer_set instead of allocating new buffer only for
2992 * Added 64-bit value formatting and unformatting support to the
2993 silc_buffer_[un]format routines. Affected file is
2994 lib/silcutil/silcbuffmt.[ch].
2996 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
2997 to includes/bitmove.h.
2999 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3001 * Fixed channel user mode saving in client library. Affected
3002 file lib/silcclient/command[_reply].c.
3004 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3006 * Defined the file transfer to the SILC Protocol. Added
3007 new packet type SILC_PACKET_FTP and defined File Transfer
3008 Payload. The mandatory file transfer protocol is SFTP
3009 (SSH File Transfer Protocol). Affected file in addition
3010 of the internet draft is lib/silccore/silcpacket.h.
3012 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
3013 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
3014 is used as part of backup router protocol when the primary
3015 router of the cell is back online and wishes to resume
3016 the position as primary router.
3018 * Redefined the MAC generation keys in the protocol. The
3019 same key is not used anymore in both direction. Both
3020 direction will now use different keys for sending and
3021 receiving. This fixes a potential security flaw. This
3022 change causes incompatibilities in the protocol.
3024 * Redefined also the MAC computation from the packet.
3025 An packet sequence number is now added to the MAC
3026 computation. This prevents possible replay attacks against
3027 the protocol. This change too causes incompatibilities
3030 Added `sequence' field to the SilcPacketContext to hold
3031 the current sequence number for the packet.
3033 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3035 * Added `created' field to the SilcIDListData in the file
3036 silcd/idlist.h to indicate the time when the entry was
3039 * Added `created' field to the SilcChannelEntry too. Affected
3040 file silcd/idlist.h.
3042 * Added `creation_time' aguments to all the announcement functions
3043 in the server. If it is provided then only the entries that
3044 was created after the provided time frame are actually
3045 announced. Affected file silcd/server.[ch].
3047 * The protocol says that the Channel ID's IP address must be
3048 based on the router's IP address. Added check for this in
3049 the silc_server_new_channel when processing incoming New Channel
3050 Payload. Affected file silcd/packet_receive.c.
3052 * Print out the correct version with --version in SILC client.
3053 Affected file irssi/src/silc/core/silc-core.c.
3055 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3057 * Fixed WHOWAS command to check for completnes of the client
3058 entry always, not just when the command is coming from client.
3059 Affected file silcd/command.c.
3061 * Added new function silc_server_packet_queue_purge to purge the
3062 outgoing data queue to the network. After the function returns
3063 it is guaranteed that the outgoing packet queue is empty.
3064 Affected file silcd/packet_send.[ch].
3066 * Purge the outgoing packet queue in the rekey protocol's final
3067 callback to assure that all rekey packets go to the network
3068 before quitting the protocol. Affected file silcd/server.c.
3070 * Added silc_client_packet_queue_parse as similar function as
3071 in server to the client library. The affected file is
3072 lib/silcclient/client.c.
3074 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3076 * Splitted silcd/server.c and created silcd/server_util.[ch]
3077 for utility functions.
3079 * Added new socket flag SILC_SF_DISABLED to indicate that the
3080 connection is open but nothing can be sent to or received from
3081 the connection. Affected file lib/silcutil/silsockconn.[ch].
3082 The checking for disabled socket is checked in the low level
3083 silc_socket_write and silc_socket_read functions.
3085 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3087 * Allow only nicknames and channel names that fits into the
3088 7-bit unsigned char ASCII set. Affected file silcd/command.c.
3090 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3092 * When processing JOIN command reply in server check that if
3093 the channel exists in our global list we'll move it the local
3094 list. Affected file silcd/command_reply.c.
3096 * Fixed the check whether client is joined on the channel already
3097 in JOIN command. Affected file lib/silcclient/command.c.
3099 * Fixed the JOIN command reply to check whether the channel
3100 already exists. Affected file lib/silcclient/command_reply.c.
3102 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3104 * Added silc_ske_status_string to map the SKE error numbers
3105 to readable strings. The affected files are
3106 lib/silcske/silcske[_status].[ch].
3108 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3110 * Do not show the private channels on the WHOIS channel list
3111 as it is not allowed by the protocol. The affected file is
3114 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3116 * Assure that the packet length digged from the actual packet
3117 is something sensible in the silc_packet_decrypt_rest_special
3118 in lib/silccrypt/silcpacket.c.
3120 * Free and NULL the allocated pointer in silc_hmac_alloc if
3121 the HMAC allocation fails. The affected file is
3122 lib/silccrypt/silchmac.c.
3124 * Print the selected security properties to the log files in
3125 the server. Affected file silcd/protocol.c.
3127 * Add SKE's reference counter even if calling the completion
3128 callback manually. Otherwise it goes negative, although it
3129 does not cause any problems. The affected file is
3130 lib/silcske/silcske.c.
3132 * Remove the client entry with short timeout after giving the
3133 KILL command. Affected file lib/silcclient/command.c.
3135 * Fixed to send error reply in WHOIS and IDENTIFY commands in
3136 case all found clients are already disconnected (WHOWAS would
3137 found them) in the server. Affected file silcd/command.c.
3139 * Update the last_receive (time of last data received) to be
3140 updated only when received private or channel message so that
3141 the idle time showed in WHOIS makes more sense.
3143 * Added boolean field `valid' in to the SilcClientEntry in the
3144 client library to indicate whether the entry is valid or not.
3145 This fixes the nickname change bug on channel when changing
3146 the nickname to be same than the old (like nick to Nick) the
3147 nickname formatter doesn't set the new nick anymore to Nick@host.
3148 Affected file lib/silcclient/idlist.[ch].
3150 * Now actually fixed the nickname changing on disconnection.
3151 Added new function silc_change_nick to the Irssi SILC Client.
3152 Affected file irssi/src/silc/core/client_ops.c,
3153 irssi/src/silc/core/silc-nicklist.[ch].
3155 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3157 * Check that the public key exists in the GETKEY command before
3158 trying to encode it. Affected file silcd/command.c.
3160 * Print some notifications on received public keys with GETKEY
3161 command in the Irssi SILC Client. Affected files are
3162 irssi/src/fe-common/silc/module-formats.[ch],
3163 irssi/src/silc/core/client_ops.c.
3165 * Use IDENTIFY command to resolve the server information in the
3166 GETKEY command instead of INFO command. Affected file
3167 lib/silcclient/command.c.
3169 * All command reply functions in the client library now calls
3170 the pending command reply callbacks even if an error has
3171 occurred. The server has done this a long time and now it was
3172 time to move the client library to this as well. Now all
3173 errors can be delivered back to the pending command reply
3174 callbacks if necessary. Affected files are
3175 lib/silcclient/command[_reply].[ch].
3177 * Change the nickname on disconnection back to the username
3178 because in reconnect the server will enforce it to it anyway.
3179 Affected file irssi/src/silc/core/silc-servers.c.
3181 * Fixed a config file parsing bug in the Irssi SILC client.
3182 Affected file irssi/src/silc/core/clientconfig.c.
3184 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3186 * When printing the channel mode on JOIN, verify that the
3187 channel key and channel's HMAC are valid. Affected file
3188 irssi/src/silc/core/client_ops.c.
3190 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3192 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
3193 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
3194 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
3196 * Removed channel key rekey task deleting from the function
3197 silc_server_save_channel_key. Affected file silcd/server.c.
3198 Added explicit timeout task context instead that is used to
3199 delete the task if we are registering a new task before the
3200 new task has elapsed.
3202 * When channel key rekey occurs the client library now saves
3203 the old channel key for a short period of time (10 seconds) and
3204 is able to use it in case some is still sending channel
3205 messages encrypted with the old key after the rekey. Affected
3206 file lib/silcclient/[idlist.h|client_channel.c].
3208 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3210 * Added check to the silc_server_new_id_real to not accept
3211 new ID if it is the sender's own ID. Affected file is
3212 silcd/packet_receive.c.
3214 * Assure that we do not announce ourself or the one we've
3215 sending our announcements when we're router and are announcing
3216 servers to our primary router. Affected file silcd/server.c.
3218 * Fixed silc_server_command_identify_check_client to assemble
3219 correct WHOIS packet. It send corrupted WHOIS packet and
3220 caused problem with router to router connections. Affected
3221 file silcd/command.c.
3223 Fixed also silc_server_command_whois_check the same way
3224 as for the IDENTIFY command.
3226 * Added new SilcIDListStatus to the server in the SilcIDListData
3227 structure. The status now includes the current status of
3228 the entry (like registered, resolved etc.). Affected file
3229 silcd/idlist.[ch]. Defined a bunch of different status types
3230 as well. This replaced the old boolean registered field as well.
3232 Added resolve_cmd_ident field to the SilcClientEntry structure
3233 too so that if the entry is for example being resolved so
3234 another command may attach to the same pending command reply
3235 without requiring to resolve the same entry again. This concept
3236 should optimize the WHOIS and the IDENTIFY resolving under
3237 heavy load by taking away unnecessary resolving for entries
3238 that are being resolved already.
3240 Added support for adding multiple pending commands for one
3241 command idenfier. Affected file silcd/command[_reply].[ch].
3243 * Fixed WHOIS and IDENTIFY save to remove the cache entry
3244 before deleting the data. Otherwise the hash table will have
3245 freed data in comparison functions. Affected file is
3246 silcd/command_reply.c.
3248 * Fixed silc_idlist_replace_client_id to add the new entry to
3249 the cache with NULL nickname. Otherwise there will be invalid
3250 memory as the nickname after the nickname is freed. Affected
3251 file silcd/packet_receive.c.
3253 * Fixed the silc_idlist_get_clients_by_hash. The entries was
3254 saved into wrong slots because the previous number of entries
3255 was not taken into account. Affected file silcd/idlist.c.
3256 Fixed same thing in silc_idlist_get_clients_by_nickname too.
3258 * If we are router and we receive JOIN notify to a channel that
3259 does not have any users then notified client is marked as the
3260 channel founder, as it is it. The affected file is
3261 silcd/packet_receive.c
3263 * Added to the extended hash table API's table_del_*ext functions
3264 the destructor as argument too, so that the caller can decide
3265 which destructor to use or whether to use destructor at all.
3266 Affected file lib/silcutil/silchashtable.[ch].
3268 * Fixed ID Cache purging. It actually deleted the entries from
3269 the hash table after the data was freed. The hash table ended
3270 up comparing freed memory. The affected file is
3271 lib/silccore/silcidcache.c.
3273 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3275 * Fixed Irssi SILC client's KILL command's HELP syntax.
3277 * The USERS command now resolves the detailed user information
3278 if the userinfo field is missing. Affected file is
3279 lib/silcclient/command_reply.c.
3281 * Do not print error in silc_file_read if the read file does
3282 not exist. Just silently return NULL. Affected file is
3283 lib/silcutil/silcutil.c.
3285 * Fixed the silc_log_output to not wine about NULL filename
3286 and to not create some bogus " " filename. Affected file is
3287 lib/silcutil/silclog.c.
3289 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3291 * Fixed various printing bugs on the user interface in the
3292 Irssi SILC Client. Minor changes that were forgotten from
3295 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3297 * Fixed the configure.in.pre and the compilation and distribution
3298 environment to support the new autoconf 2.52. That version is
3299 now required to compile the CVS trunk.
3301 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3303 * Renamed function silc_parse_nickname to silc_parse_userfqdn
3304 to generally parse user@fqdn format strings. Affected file
3305 lib/silcutil/silcutil.c.
3307 * Added nickname_format and nickname_force_format fields to the
3308 SilcClientParams structure. The first one defines the format
3309 for the nicknames that the library will enforce if the receives
3310 multiple same nicknames. The second one is boolean value and
3311 can be used to force the library to always enforce the format
3312 to the nicknames regardles whether there are multiple nicknames
3313 or not. This configurable formatting was employed to flexibly
3314 support accessing multiple nicknames from the user interface.
3315 The userinterface can now set the nicknames to what ever format
3316 they prefer. Affected file lib/silcclient/silcapi.h.
3318 Added function silc_client_nickname_format to the file
3319 lib/silcclient/idlist.c. It performs the nickname formatting.
3321 Added new field `hostname´ to the SilcClientEntry context.
3322 It holds the hostname of the client. Affected file is
3323 lib/silcclient/idlist.h.
3325 * Irssi SILC Client sets the nicknames in nick@hostn format.
3326 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
3327 irssi/src/silc/core/silc-core.c.
3329 The WHOIS printing now also shows both the real nickname and
3330 the formatted nickname so that user knows how to access the
3331 user if there are multiple same nicknames cached. Affected
3332 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
3333 printing formatting too to take the hostname now as a separate
3334 argument. The Affected file is
3335 irssi/src/fe-common/silc/modules-formats.[ch].
3337 * Changed the silc_client_get_clients_local to accept the formatted
3338 nickname as argument. It accepts the real nickname too but the
3339 formatted nickname can be used to find the true entry from
3340 multiple entries. Affected file lib/silcclient/silcapi.h and
3341 lib/silcclient/idlist.c.
3343 * Added nickname_format_parse field to the SilcClientParams.
3344 It is a callback function provided by the application to parse
3345 the nickname out of the formatted nickname string. The library
3346 calls it to get the nickname from the formatted string. Since
3347 the application generally knows better the format of the nickname
3348 string it parses it instead of the library, even though library
3349 encodes the formatted string. If the callback function is not
3350 provided then the library will use the string as is. The
3351 affected file is lib/silcclient/silcapi.h.
3353 * All the nickname strings passed to the client library in
3354 commands are now expected to be formatted nickname strings.
3355 If the command does not support the formatted nickname string
3356 it will assume that the sent string is the actual nickname.
3357 Affected file lib/silcclient/command.c.
3359 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3361 * Added public key authentication support to OPER and SILCOPER
3362 commands in the client library. Affected file is
3363 lib/silcclient/command.c.
3365 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3367 * Changed the get_auth_methdod client operation to be asynchronous.
3368 It can be async if the application resolves the authentication
3369 method from the server during the negotiation. Added new
3370 SilcGetAuthMeth completion callback that the application will
3371 call after resolving the authentication method.
3373 Added function silc_client_request_authentication_method that
3374 the application can use to resolve the authentication method
3375 from the server. Added also SilcConnectionAuthRequest callback
3376 that the library will call after the server has replied. The
3377 application can call this function if it does not know the
3378 current authentication method.
3380 Affected files are lib/silcclient/client.c and
3381 lib/silcclient/silcapi.h.
3383 * The Irssi SILC client now automatically resolves the authentication
3384 method incase any configuration information is not present (and
3385 currently there never is). The affected file is
3386 irssi/src/silc/core/client_ops.c.
3388 * Fixed public key authentication from the client library.
3389 Affected file lib/silcclient/protocol.c. Changed also the
3390 protocol specification about the public key authentication in
3391 the connection authentication protocol. The actual data to be
3392 signed is now computed with a hash function before signing.
3394 * Fixed the public key authentication from the server as well.
3395 Affected file silcd/protocol.c.
3397 * Removed the mlock()'s from the memory allocation routines.
3398 Affected file lib/silcutil/silcmemory.c. The ./configure does
3399 not check anymore for the mlock(). Affected file is
3402 * Fixed USERS command in server to allow the execution of the
3403 command for private and secret channels if the client sending
3404 the command is on the channel. Affected file silcd/command.c.
3406 * Fixed silc_client_get_clients_local to return the clients
3407 count correctly. It could return wrong value. Affected file
3408 lib/silcclient/idlist.c.
3410 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3412 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
3413 types. The assembler optimizations seemed not to like 64-bit
3414 data types. The assmebler optimizations thus are now enabled
3415 also for BSD systems as opposed to only enable them for Linux.
3417 * Do not check for threads at all on BSD systems. Affected
3418 file configure.in.pre.
3420 * Removed -n and -h options from the Irssi SILC Client since
3421 they are not used in silc.
3423 * Fixed the prime generation to assure that the first digit
3424 of the generated random number is not zero since our conversion
3425 routines does not like number strings that starts with zero
3426 digit. If zero digit is seen the random number is regenerated.
3427 This caused some corrupted RSA keys when the zero first digit
3428 was met. Affected file lib/silcmath/silcprimegen.c.
3430 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3432 * Fixed WIN32 configuration in the ./configure script.
3433 Fixed to include xti.h on environments that has it.
3434 Patches by Carsten Ilchmann and andrew.
3436 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3438 * Changed the silc_id_create_client_id to be collision
3439 resistant. It is now assured that there cannot be created
3440 two same client ID's. I suspect that some weird bugs in
3441 the server were actually caused by duplicate Client IDs.
3442 Affected file silcd/serverid.[ch]. A router receiving
3443 new ID now also assures and informs the sending server
3444 if the ID caused collision.
3446 * Changed the silc_id_create_channel_id to also assure that
3447 there are no collisions.
3449 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3451 * Statement about ignoring the Mutual Authentication flag when
3452 performing rekey with PFS was a bit misleading. It is ignored
3453 if it was set in the initial negotiation, it cannot be even
3454 set in the rekey. Fixed in the ke-auth draft. Started the
3455 new versions of the protocol drafts in the doc/.
3457 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3459 * Fixed a bug in silc_client_command_identify_save when saving
3460 new channel information. The channel name was no duplicated
3461 and caused crash on exit. Affected file is
3462 lib/silcclient/command_reply.c.
3464 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3466 * Fixed the getkey command handling in the server. Send just
3467 empty OK reply to the sender if the key could not be fetched
3468 (but everything else was ok, like the key just was not available).
3469 Changed the public key parameter to optional in the protocol
3470 specs so that empty OK reply can be sent. Affected file
3473 Added a message to Irssi SILC client to tell to user if the
3474 server did not return a public key.
3476 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3478 * Fixed a channel key regeneration bug. It registered new
3479 timeout tasks exponentially until all system resources were
3480 used. Affected file silcd/server.c.
3482 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3484 * Added the SILC Document generator to the scripts/silcdoc.
3485 It can be used to generate the Toolkit Reference Manual out
3486 of the source tree. Internally it will also use the RoboDoc
3487 generator now imported in util/robodoc.
3489 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3491 * Added couple of return's in rekey protocol if error orccurred
3492 during the protocol. The execution must be terminated.
3493 Affected file silcd/protocol.c. Also, terminate the protocol
3494 always with timeout.
3496 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3498 * The client's Client ID was created initally from the wrong
3499 nickname (it could have been in format nick@host) in the
3500 silc_server_new_client. Affected file silcd/packet_receive.c
3502 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3504 * Added some SILC_LOG_ERROR's to various error conditions
3505 if client could not be added to ID cache. Affected files
3506 silcd/packet_receive.c and silcd/server.c.
3508 * When client's sock->user_data is freed, NULL also the
3509 client->router and client->connection pointers. Added check
3510 for these pointers being NULL to various places around the
3511 code. Affected file silcd/server.c.
3513 * Added client->data.registered == TRUE checks to various
3514 places around the code to assure that unregistered client's
3515 are not handled when it is not allowed. Affected file
3518 * Added `bool registered' fields to all
3519 silc_idlist_[server|client]_get_* routines to indicate whether
3520 the fetched client needs to be registered or not. Affected
3521 file silcd/idlist.[ch].
3523 * Add your own entry as registered to the ID cache in the
3524 server. Affected file server.c.
3526 * Fixed a bug in silc_server_new_server. The SilcServer was
3527 set as the new server's context instead of SilcServerEntry.
3528 This naturally caused some weird bugs.
3530 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3532 * Do not delete the channel rekey task when adding it
3533 for in silc_server_create_channel_key.
3535 * Changed the silc_server_create_channel_key to return
3536 TRUE or FALSE to indicate the success of the channel key
3539 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3541 * Fixed MSVC++ project files and added missing files to
3542 Makefiles under win32/.
3544 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3546 * Do not add TCP_NODELAY flag if the operating system
3547 does not have it defined. Affected files are
3548 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3550 * Fixed buffer overflow from Irssi SILC Client. Affected
3551 file irssi/src/fe-common/core/themes.c.
3553 * Fixed double free in client library in the file
3554 lib/silcclient/client.c when disconnecting from server.
3556 * Applied double free patch from cras to Irssi SILC client.
3557 Affected files irssi/src/core/[modules/expandos].c
3559 * Fixed the disconnection handling to Irssi SILC Client.
3560 The application must call silc_client_close_connection
3561 in ops->connect client operation in case of failure of
3562 the connection. Affected file is
3563 irssi/src/silc/core/client_ops.c.
3565 * Do not set sock->protocol to NULL in the function
3566 silc_client_close_connection after executing the protocol's
3567 final callback since the sock might not be valid anymore.
3568 Affected file lib/silcclient/client.c.
3570 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3572 * Do not enable SILC_THREADS if the linking with libpthread
3573 did not happen. Affected file configure.in.pre.
3575 * Added notion to protocol specification that server must
3576 verify the sent authentication payload with CMODE when
3577 setting the channel founder key. Implemented it to the
3578 server. Affected file silcd/command.c.
3580 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3582 * Added _EXTRA_DIST SILC distribution variable to the
3583 distributions file. It is used to conditionally add extra
3584 files or directories to the specific distribution. Affected
3585 files ./prepare, Makefile.am.pre and distributions.
3587 Removed the `_' from the start of the distribution names.
3590 * Added README.WIN32 for instructions to compile the Toolkit
3593 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3595 * Fixed a double free in disconnection in the server. Affected
3596 file is silcd/server.c.
3598 * Fixed the lib/silcske/groups.c to work now also with GMP
3599 MP library. The string conversion did not work when using
3600 specific base and the base is indicated in the string as well.
3602 * Created win32/ directory which now includes MSVC++ specific
3603 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3604 It will appear only in the toolkit distribution
3606 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3608 * Changed the key material distribution function in case when
3609 the hash output is too short. The data is now concatenated
3610 a bit differently than it used to. Made the change to the
3611 SKE protocol specification.
3613 * Added better GMP detection to configure.in.pre. A patch
3616 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3618 * Fixed a minor bug in SKE that might cause some problem on
3619 some platforms. Affected file lib/silcske/silcske.c.
3621 * Added the cookie checking for initiator in the SKE. It checks
3622 that the responder returns the sent cookie unmodified. The
3623 affected file is lib/silcske/silcske.c. Added new SKE
3624 error type INVALID_COOKIE that can be sent during the
3625 negotiation. Fixed some memory leaks as well.
3627 * Added the "invalid cookie" error message to Irssi SILC client's
3630 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3632 * Added `task_max' field to the SilcClientParams to indicate
3633 the maximum tasks the scheduler can handle. If set to zero,
3634 default values are used. Affected file lib/silcclient/silcapi.h.
3636 * Fixed memory leaks in silc_client_close_connection. Affected
3637 file lib/silcclient/client.c.
3639 * Added silc_client_del_client_entry to client library to free
3640 all memory of given client entry. Affected file is
3641 lib/silcclient/idlist.[ch].
3643 * Added new functions silc_client_del_channel and
3644 silc_client_del_server to delete channel and server entries.
3645 Affected file lib/silcclient/[silcapi.h/idlist.c].
3647 * Removed silc_client_del_client_by_id from silcapi.h.
3649 * Fixed the INFO command to return the server's own info
3650 correctly when querying by Server ID. Affected file is
3653 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3655 * Removed the non-blocking settings in WIN32 code in the
3656 silc_sock_[read/write] and added SleepEx instead. Affected
3657 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3658 of input data is now checked with FIONREAD and ioctlsocket.
3660 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3662 * Call silc_schedule_task_del_by_context in the
3663 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3664 Affected file lib/silccore/silcprotocol.c.
3666 * Call silc_protocol_cancel for active protocols in the
3667 silc_server_close_connection if the funtion
3668 silc_server_free_sock_user_data has not been called.
3669 Affected file silcd/server.c.
3671 * Generic tasks cannot be deleted using the del_by_fd
3672 task deleting function since generic tasks does not match
3673 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3675 * Added a notion to SILCOPER help file that the SILCOPER works
3676 only on router server, not on normal server.
3678 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3680 * Added for WIN32 support for the new scheduler as well.
3681 Affected file lib/silcutil/win32/silcwin32schedule.c.
3683 * Fixed the SHA1 implementation to work on various platforms.
3685 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3687 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3688 API. It is part of the scheduler now. Everything else is
3689 as previously but some functions has changed their names.
3690 Checkout the lib/silcutil/silcschedule.h for the interface.
3691 Updated all applications to use the new interface. Affected
3692 files are lib/silcutil/silcschedule.[ch].
3694 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3696 * Found a bug in the SKE implementation. The HASH value,
3697 specified by the protocol, was not computed correctly. The
3698 public key of the responder was not added to the computation
3699 even though it is mandatory. Affected file lib/silcske/silcske.c.
3700 This unfortunately causes incompatibilities with older
3701 clients and servers.
3703 * Added WIN32 specific network init and uninit functions:
3704 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3705 the Winsock2. Affected file lib/silcutil/silcnet.h and
3706 lib/silcutil/win32/silcwin32net.c.
3708 * Set the socket always to nonblocking mode on WIN32 after
3709 reading data or writing data. Affected file is
3710 lib/silcutil/win32/silcwin32sockconn.c.
3712 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3714 * Fixed various compilation problems under WIN32. Affected
3715 files lib/silcutil/win32/silcwin32thread.c and
3716 lib/silcutil/win32/silcwin32schedule.c.
3718 * Removed all _internal.h #includes from public header
3719 files. Internal headers must never be included from
3722 Removed also the lib/silcske/payload_internal.h file.
3724 * All include files that may be needed (public and some others
3725 included by the public headers) by application developers are
3726 now copied to the ./includes directory. It does not copy any
3727 internal headers. Affected file Makefile.defines.pre and all
3728 Makefile.am's under lib/ and subdirs.
3730 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3732 * Do not change the ~/.silc directory's permissions automatically.
3733 Affected file irssi/src/silc/core/clientutil.c.
3735 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3737 * Do not cancel the protocol in silc_server_close_connection
3738 it might cause recursion. Now cancelled in the function
3739 silc_server_free_sock_user_data. Affected file silcd/server.c.
3741 * Fixed the silc_server_remove_clients_by_server to regenerate
3742 the channel keys correctly finally. Added also new function
3743 silc_server_remove_clients_channels to actually do it.
3744 Affected file silcd/server.c.
3746 * Fixed the silc_server_new_channel to not crash by giving
3747 wrong router to the new channel. Affected file is
3748 silcd/packet_receive.c.
3750 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3752 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3753 which is given as argument to the silc_client_alloc now.
3754 It can be used to configure the client and set various parameters
3755 that affect the function of the client.
3757 * The USERS command in server did not check whether the channel
3758 is private or secret. Affected file silcd/command.c.
3760 * Added new argument to the USERS command in protocol specification.
3761 The USERS command now can take the channel name as argument
3762 as well. Added support for this in client and server and
3763 updated the protocol specs.
3765 * Completed the GETKEY command in client. It can be now used
3766 to fetch also servers public key not only some clients.
3767 Affected files lib/silcclient/command[_reply].c.
3769 * Added silc_client_get_server to return server entry by the
3770 server name. Affected files lib/silcclient/silcapi.h and
3773 * Redefined the IDENTIFY command in protocol specification to be
3774 more generic. It now can be used to query information about
3775 any entity in the SILC Network, including clients, servers and
3776 channels. The query may be based either the entity's name
3777 or the ID. Added support for this in both client and server.
3779 Affected files silcd/command.c and lib/silcclient/command.c
3780 and command_reply.c.
3782 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3783 the _from_client and _from_server functions. Affected file
3786 * Added silc_client_get_channel_by_id_resolve to the file
3787 lib/silcclient/silcapi.h to resolve channel information by
3788 its ID. Added also silc_client_get_channel_by_id that
3789 does not resolve it from the server.
3791 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3793 * Added SilcServerEntry context into the client library
3794 to represent one server. The INFO command now allocates
3795 these to save the resolved server info. For now on the
3796 client library will also keep information about servers,
3797 connected and resolved with INFO.
3799 The INFO command now allocates the SilcServerEntry context
3800 and saves the server info there. The COMMAND_REPLY in
3801 the INFO now returns the parameters to application in
3802 same order as defined in the protocol specification.
3804 The entries are cached in the client->server_cache.
3806 * The INFO command is now issued after received the Client ID
3807 from the server. Affected file lib/silcclient/client.c.
3809 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3810 to the application as the mode changer might be server.
3811 It is guaranteed that NULL is not returned anymore to the
3812 application. Affected file lib/silcclient/client_notify.c.
3814 The ID Type is now also passed to the application so that
3815 it can check whether the returned entry is SilcClientEntry
3818 Added new function silc_client_get_server_by_id to return
3819 the server entry by ID. Affected files are the
3820 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3822 * Do not create the channel in the Irssi SILC Client when issuing
3823 the JOIN command but when received the sucessful JOIN command
3824 reply. Otherwise the channel might get created even though we
3825 could not join it. The Affected file is
3826 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3828 * Fixed a channel joining bug in router. The router must also
3829 check the channel modes, invite and ban lists etc. when serving
3830 the JOIN command sent by normal server. Affected file is
3831 silcd/command.c. The router now resolves the client's
3832 information from the server who sent the JOIN command if it
3833 does not know it, and processes the JOIN command only after
3836 * Changed the SilcCommandCb to take new argument; void *context2.
3837 Affected file lib/silccore/silccommand.h
3839 The second argument in the command callbacks in the server now
3840 includes the SilcServerCommandReplyContext if the command was
3841 called as pending command callback from the command reply.
3842 Otherwise it is NULL. When called as pending the status of the
3843 command reply will be checked and if it was erronous the
3844 error will be sent to the original sender of the command.
3845 This way the client always receives the error messages even
3846 though the server was actually the one who received the error
3847 when it resent the command to router, for example. Affected
3848 files silcd/command[_reply].[ch].
3850 * Fixed sending WHOWAS command's error message to client if
3851 the requested client could not be found. It was missing.
3854 * Changed the CMODE and CUMODE commands reply arguments in the
3855 protocol specification. The Channel ID is now sent in both
3856 of the commands to identify the channel. Implemented this
3857 new feature to the client and server. Affected files
3858 lib/silcclient/command_reply.c and silcd/command.c.
3860 * Made better checks for invite and ban lists in the JOIN
3861 command in server. Affected file silcd/command.c.
3863 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3865 * The server now performs the incoming host IP/DNS lookup
3866 using the silc_socket_host_lookup and thus does not block
3867 the server anymore. Affected file silcd/server.c.
3869 * Completed the multi-thread support for SILC Scheduler in
3870 the lib/silcutil/silcschedule.c.
3872 * Fixed the configure.in.pre to detect the pthread correctly
3875 * Fixed a deadlock in silc_task_queue_wakeup in the file
3876 lib/silcutil/silctask.c.
3878 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3880 * Added new function silc_schedule_wakeup that is used in
3881 multi-threaded environment to wakeup the main thread's
3882 schduler. It needs to be used when a thread adds a new task
3883 or removes a task from task queues. After waking up, the
3884 scheduler will detect the task queue changes. If threads
3885 support is not compiled in this function has no effect.
3886 Implemented the wakeup mechanism to both Unix and WIN32
3887 systems. Affected files are lib/silcutil/silcschedule.[ch],
3888 lib/silcutil/unix/silcunixschedule.c and the
3889 lib/silcutil/win32/silcwin32schedule.c.
3891 * Added new function silc_task_queue_wakeup to wakeup the
3892 scheduler by the specified task queue. Affected file
3893 lib/silcutil/silctask.[ch].
3895 * The silc_socket_host_lookup_start now wakes up the scheduler
3896 after adding the timeout task. Affected file is
3897 lib/silcutil/silcsockconn.c.
3899 * The silc_socket_host_lookup is synchronous now if the threads
3900 support is not compiled in. However, the callback is still
3901 called asyncronously through the scheduler, anyway. Affected
3902 file lib/silcutil/silcsockconn.c.
3904 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3906 * Added new function silc_socket_host_lookup to perform
3907 asynchronous IP and FQDN lookups for the socket connection.
3908 Affected files lib/silcutil/silcsockconn.[ch].
3910 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3912 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3913 that may or may not compile the mutex support in.
3915 Changed the silc_mutex_alloc interface. It allocates the
3916 mutex now to the sent pointer and returns TRUE or FALSE.
3918 Affected file lib/silcutil/silcmutex.h.
3920 * Wrote the SILC Task Queue interface to support multi-threads.
3921 Affected file lib/silcutil/silctask.[ch].
3923 * Wrote the SILC Scheduler to support multi-threads. Affected
3924 file lib/silcutil/silcschedule.c.
3926 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3928 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3929 in lib/silcutil/win32/.
3931 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3933 * Defined SILC Mutex API and SILC Thread API and implemented
3934 them for Unix. Affected files are
3935 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3936 lib/silcutil/unix/silcunixmutex.c and
3937 lib/silcutil/unix/silcunixthread.c.
3939 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3941 * Fixed the silc_server_remove_clients_by_server's channel
3942 key re-generation. The hash table handling was incorrect
3943 and would not work with many channels. Affected file is
3946 * Fixed some memory leaks around the server code.
3948 * Rewrote the silc_server_get_users_on_channel to support IPv6
3949 based Client ID's. Affected file silcd/server.c.
3951 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3952 specification. However, a separate document must be written
3953 to define the detailed signing procedure and the payload
3954 associated with the flag. Defined the flag to the
3955 lib/silccore/silcchannel.h as well.
3957 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3959 * Changed the dynamic tables to static size tables in the
3960 lib/silccrypt/silchmac.c.
3962 * Removed GCC dependencies from the code. A patch by cras.
3964 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3966 * Do not show the error "Error receiving packet bla bla"
3967 in server if it really was not an error (-2 means that reading
3968 is pending). Affected file silcd/server.c.
3970 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3972 * Fixed a possible crash in silc_server_remove_clients_by_server
3973 in silcd/server.c. Fixed there also some memory leaks.
3975 * Fixed the silc_idlist_replace_client_id. It could replace
3976 wrong key in the hash table. Affected file silcd/idlist.c.
3978 * Do not check whether there are global users on the channel
3979 if the channel->global_users is FALSE. Affected functions
3980 silc_server_remove_from_one_channel and
3981 silc_server_remove_from_channels in silcd/server.c. Also,
3982 do not check if the removed client is local as we can be
3983 sure that global client was not removed from the channel
3984 and checking for global users is not needed.
3986 * The silc_server_remove_clients_by_server now re-generates
3987 the channel keys correctly for those channels that had
3988 clients removed from them. Affected file silcd/server.c.
3990 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3992 * Found the reason of random crashes in the server. We weren't
3993 ignoring the SIGPIPE signal (which can be sent in write())
3994 and it crashed the server. Affected file silcd/silcd.c.
3996 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3998 * Assure that sock->user_data is not NULL in the function
3999 silc_server_packet_send in silcd/packet_send.c.
4001 * Disconnect the remote connection if it could not be added
4002 to any ID lists in the server. The affected file is
4005 * Check in silc_server_packet_send[_real/dest] that the
4006 socket is not disconnecting and ignore the data if it is.
4007 Affected file silcd/packet_send.c.
4009 * Define inline to __inline on native WIN32 compilation.
4010 Affected file includes/silcwin32.h.
4012 * Added some explicit type casts for inline code since MSVC
4013 require them. Affected files lib/silcutil/silcbuffer.h,
4014 lib/trq/silcdlist.h and lib/trq/silclist.h.
4016 * Print warning in log files from now on if the packet
4017 decryption fails. Affected file silcd/server.c.
4019 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4021 * Changed the `say' client operation's interface to accept
4022 new `type' argument to indicate the type of the message sent
4023 by the library. The application may filter the library's
4024 messages according the type. The affected file is the
4025 lib/silcclient/silcapi.h.
4027 * Added two new functions to lib/silcclient/silcapi.h:
4028 silc_client_del_client and silc_client_del_client_by_id.
4029 Affected file lib/silcclient/idlist.c.
4031 * Moved the clientincludes.h from includes/ to silc/ and
4032 serverincludes.h from includes/ to silcd/.
4034 * The modes for the CMODE and CUMODE are now passed as
4035 uint32 for application with COMMAND_REPLY. The affected
4036 file is lib/silcclient/command_reply.c.
4038 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4040 * /WHOIS without arguments shows client's own information.
4041 Affected file lib/silcclient/command.c.
4043 * Changed PING to not accept any arguments. The specs
4044 says that client can ping only the connected server so
4045 requiring an argument is not needed. Affected file is
4046 lib/silcclient/command.c.
4048 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4050 * Fixed a fatal bug in private message sending and reception
4051 encryption and decryption when using private message keys.
4052 The implementation was incorrect and did not follow the
4053 specification. It causd that some of the message were
4054 lost since it did not use the sending and receiving keys
4055 as the protocol suggests. This has been fixed and will cause
4056 incompatibilities with older clients when sending private
4057 message encrypted with private message keys. Affected files
4058 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
4059 and various other in Irssi SILC Client.
4061 Added `responder' boolean argument to the functions
4062 silc_client_add_private_message_key[_ske] to indicate when
4063 the key is added as responder or initiator of the key
4066 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4068 * Removed the silc_ske_check_version function and created
4069 a SilcSKECheckVersion callback. Added also a function
4070 silc_ske_set_callbacks that is now used to set all SKE
4071 callbacks. The callback functions are not given to
4072 the SKE functions anymore, but this function is used to
4075 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
4077 * Added `silc_version' argument to the silc_client_alloc
4078 to define the version of the application for the library.
4079 The library will use the version string to compare it
4080 against the remote host's (usually a server) version
4081 string. Affected file lib/silcclient/silcapi.h
4083 * Added the KE protocol context to Key Agreement context
4084 in client library so that we can abort the SKE if it
4085 is in process when we get timeout. Affected file is
4086 lib/silcclient/client_keyagr.c.
4088 * Do not resolve the client ID forever if it returns in the
4089 first time that such client does not exist. This was done
4090 for example with private message. Affected file is
4091 lib/silcclient/client_prvmsg.c.
4093 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4095 * Do not add regex.h for WIN32. The affected file
4096 includes/silcincludes.h.
4098 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
4099 not work yet 100%. It generates the DLL's automatically
4100 when compiling with --with-win32 under cygwin.
4102 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4104 * lib/contrib/regex.c is not compiled on WIN32.
4106 * Added silc_net_get_socket_opt function to the
4107 lib/silcutil/silcnet.h.
4109 * Added includes/silcwin32.h for WIN32 specific includes
4112 * Do not use ptime structure or any of the posix process
4113 functions on WIN32 in lib/silccrypt/silrng.c.
4115 * Added silc_gettimeofday to provide generic function
4116 for struct timeval on all platforms. Added the function
4117 to lib/silcutil/silcutil.h.
4119 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4121 * Moved the lib/silccore/silcsockconn.[ch] to the utility
4122 library as they clearly belong there. As a plus side we
4123 can make the actual socket connection routines platform
4126 Added also new generic function silc_socket_read and
4127 silc_socket_write (that used to be silc_packet_[read/write].
4128 The implementation of these are platform specific.
4130 * Added WIN32 specific routines of silc_socket_[read/write]
4131 to lib/silcutil/win32/silcwin32sockconn.c.
4133 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4135 * Added preliminary support for native WIN32 compilation under
4136 cygwin (using the -mno-cygwin option for GCC) to the
4137 ./configure.in.pre. The --with-win32 now prepares the
4138 compilation for native WIN32.
4140 * Rewrote the SILC Scheduler interface in the file
4141 lib/silcutil/silcschedule.h. The scheduler is now context
4142 based and does not have anymore any global static scheduler.
4143 Moved the Unix scheduler to the lib/silcutil/unix/ directory
4144 and created lib/silcutil/win32 directory for WIN32 based
4147 * Added Unix specific network routines to the
4148 lib/silcutil/unix/silcunixnet.c and the old
4149 lib/silcutil/silcnet.c includes now only generic routines.
4151 Added WIN32 specific network routines to the
4152 lib/silcutil/win32/silcwin32net.c.
4154 * Added Unix specific utility functions from the
4155 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
4157 * Added WIN32 SILC Scheduler to the file
4158 lib/silcutil/win32/silcwin32schedule.c. The code is of course
4161 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4163 * Do not handle JOIN notify in the server if the target client
4164 is not registered (idata->registered == FALSE). The affected
4165 file is silcd/packet_receive.c.
4167 * Update the nickrec->founder in event_cumode in the Irssi SILC
4168 client. Affected file irssi/src/silc/core/silc-channels.c.
4170 * Fixed the CUMODE_CHANGE notify handling in the server when
4171 server and router are announcing their clients on channels.
4172 Now the mode changes are saved and notified correctly. The
4173 affected file is /silcd/packet_receive.c.
4175 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
4176 They really did not replace the cache entry in the ID Cache.
4177 Now they do that. Affected file silcd/idlist.c.
4179 * Fixed the KICK notify handling in the Irssi SILC client to
4180 update the channel records so that the kicked client does not
4181 appear to be on the channel. The affected file is
4182 irssi/src/silc/core/silc-channels.c.
4184 * Always update the conn->current_channel when executing command
4185 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
4187 * Fixed the KILL notify handling in Irssi SILC client to remove
4188 the killed client on all channels.
4190 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4192 * Fixed the silc_parse_command_line to remove extra spaces
4193 from the start and end of the arguments. Affected file is
4194 lib/silcutil/silcutil.c.
4196 * Cancel and free any active protocol in the function
4197 silc_server_close_connection. Affected file silcd/server.c.
4199 * Cancel and free any active protocol in the function
4200 silc_client_close_connction. Affected file is
4201 lib/silcclient/client.c.
4203 * Do not execute the KILL command for clients that are in
4204 history (ie. they are not in the network). Affected file is
4207 * Fixed KILL notify handling, client does not crash anymore.
4208 Affected file irssi/src/silc/core/silc-channels.c.
4210 * Reduced the default packet buffer size from 2048 to 1024 in
4211 lib/silccore/silcpacket.c.
4213 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
4214 counter to the SKE context that is incresed when the SKE library
4215 performs async operation outside the library. If the outside
4216 process frees the SKE context and FREED status will be set
4217 and the library will detect after the sync operation that the
4218 libary is freed. The affected files are
4219 lib/silcske/silcske[_status].[ch].
4221 * Resolve the client entry information in the function
4222 silc_client_channel_message to assure that NULL pointer is not
4223 passed as client entry to the application. */
4225 * Fixed the task timeout calculation to assure that there is
4226 never negative timeouts. The affected file is
4227 lib/silcutil/silcschedule.c.
4229 * Fixed the channel user mode notification sending in server.
4230 It was sent point-to-point to the router (or to server by router)
4231 but it needs to be destined to a channel. The routines now
4232 supports sending the channel user mode notifys to the channels
4233 when announcing clients and channels. Affected files are
4234 silcd/server.c and silcd/packet_receive.c.
4236 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
4237 It did not actually replace the old channel entry in the cache.
4238 Affected file lib/silcclient/client_notify.c.
4240 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4242 * Fixed a possible crash in silc_packet_send_prepare. It now
4243 assures always that there is enough space in the buffer and
4244 at the tail area of the buffer (for MAC).
4246 Fixed the inbound buffer reallocation in silc_packet_read.
4247 It was old code and did not handle the reallocation correctly.
4250 The affected file is lib/silccore/silcpacket.c.
4252 * Fixed buffer overflow in silc_parse_nickname in the file
4253 lib/silcutil/silcutil.c.
4255 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4257 * make install generates new server keys only if there is not
4260 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4262 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
4263 Added check that if the NOREPLY is set then we will not send
4264 the away message. This avoids infinite loop of away messages
4265 if both clients are away. The affected file is
4266 lib/silcclient/client_prvmsg.c.
4268 * Fixed client crash if /NICK was given without arguments.
4269 Affected file lib/silcclient/command.c.
4271 * Server does not send the invite list in INVITE command back
4272 to the client if the list was not altered. Added this notion
4273 to the protocol spec as well. Affected file silcd/command.c.
4275 Fixed possible crash in INVITE command by checking the
4276 value of silc_server_get_client_route command.
4278 * Fixed the INVITE notify type handling. The arguments are now
4279 taken in correct order and client does not crash. The affected
4280 file is irssi/src/silc/core/silc-channels.c.
4282 Removed the "Inviting xxx to channel" message from the
4283 client library away and let the application handle it.
4284 Affected file lib/silcclient/command.c. Added that message
4285 to Irssi SILC client's message formats.
4287 * Fixed CMODE command crash in client. It now checks the
4288 amount of arguments correctly and does not crash. The affected
4289 file is lib/silcclient/command.c.
4291 * Do not create new channel automatically in silc_channels_join
4292 but check whether the channel by that name already exists.
4293 Affected file irssi/silc/core/silc-channels.c.
4295 * Do not send the SERVER_SIGNOFF to router if the disconnected
4296 entity was the router. Affected file silcd/server.c.
4298 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
4299 SILC client as it was missing from there.
4301 Added the handling of the KICK notify to the Irssi SILC client
4302 as it was missing. Added "you have been kicked" message to
4303 Irssi SILC client's message modules formats.
4305 Added the handing of the KILL notify to the Irssi SILC client
4306 as it was missing. Added the kill message module formats
4309 The affected file is irssi/src/silc/core/silc-channels.c.
4311 * The router did not save the channel mode the server announced.
4312 Affected file silcd/packet_receive.c.
4314 * Fixed a possible crash in INFO command in server. If the
4315 server did not provide the server info it crashed. Affected
4316 file silcd/command.c.
4318 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4320 * Fixed the GETKEY command in the server to check also the
4321 global list. Otherwise the GETKEY would not work correctly
4322 in normal SILC server. Affected file silcd/command.c.
4324 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4326 * Fixed GETKEY crash, it crashed if the command did not succseed.
4328 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4330 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
4331 is now real and not just an macro interface to GMP.
4333 Removed the entire GMP from the source tree and imported new
4334 NSS MPI library instead. Reason for removing GMP is that it is
4335 extremely large and compiles extremely slow. The NSS MPI
4336 is only a few files and compiles in less than 10 seconds.
4337 The speed is also about the same as GMP. The MPI is imported
4338 to lib/silcmath/mpi.
4340 If the system has GMP installed we will still use the GMP.
4341 If it is not then the NSS MPI will be compiled.
4343 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4345 * Merged a long nickname (127 characters long) crash bugfix from
4346 Irssi CVS tree. Affected file irssi/src/core/misc.c.
4348 * Merged a freed memory reference bugfix from Irssi CVS tree.
4349 Affected file irssi/src/core/commands.c.
4351 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4353 * Added the server's public key sving and verification to the
4354 server when performing the SKE. This was missing and the
4355 remote server's (or router's) public key was accepted without
4356 checking whether we have it previously or trust it at all.
4357 Affected file silcd/protocol.c.
4359 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4361 * Check in the silc_server_timeout_remote if protocol is active
4362 and make sure that the protocol's final callback is called so
4363 that all memory if freed. Affected file silcd/server.c.
4365 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4367 * silc_server_whois_send_reply crashed the server if the nickname
4368 was 127 characters long. Affected file silcd/command.c.
4370 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4372 * Added sanity check to the silc_server_new_client. If the hostname
4373 is provided inside username then check that the provided hostname
4374 really is the same as the resolved one. If the hostname was not
4375 resolved then check it from the public key. Affected file is
4376 silcd/packet_receive.c.
4378 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
4379 if the server disconnected us and the connection is not valid
4380 anymore. Affected file irssi/src/silc/core/silc-channels.c.
4382 * Moved the silc_client_[chmode|chumode|chumode_char] away from
4383 the library to the lib/silcutil/silcutil.[ch].
4385 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4387 * Close log file after open. Affected file
4388 lib/silcutil/silclog.c.
4390 * Check whether sock == NULL in silc_client_send_packet and return
4391 if it is. Affected file lib/silcclient/silcclient.c.
4393 * Check rec->entry == NULL in the Irssi SILC Client before
4394 sending the channel message. Affecte file is
4395 irssi/src/silc/core/silc-servers.c.
4397 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4399 * Merged a splitted window bugfix from Irssi CVS tree. The
4400 affected file is irssi/src/fe-text/textbuffer-view.c.
4402 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
4403 It did not print nickname.
4405 * Improved the distributions system a bit.
4407 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4409 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
4410 irssi/src/fe-text/gui-window.c.
4412 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
4413 to in-active server. The affected file is
4414 irssi/src/silc/core/client_ops.c.
4416 * Resolve the client in USERS command reply if the entry does
4417 not have username resolved. The affected file is
4418 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
4419 command to WHOIS command to really resolve stuff. The USERS
4420 is not used any more in any critical section so WHOIS can
4421 be used even though it might be slower than IDENTIFY.
4423 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
4426 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4428 * Changed the protocol API a bit more consistent in the
4429 lib/silccore/silcprotocol.[ch].
4431 * Changed the following headers to ROBODoc format:
4433 lib/silccore/silcpayload.h
4434 lib/silccore/silcprotocol.h
4435 lib/silccore/silcsockconn.h
4437 All core library headers are now formatted.
4439 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4441 * Fixed a bug in Irssi SILC client; do not show that you are
4442 server/router operator if you really are not. Affected file is
4443 irssi/src/silc/core/client_ops.c.
4445 * Renamed silc_command_free_payload to silc_command_payload_free.
4446 Affected file lib/silccore/silccommand.h
4448 * Added silcmath.h to include the prototoypes of various routines
4449 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
4452 * Changed the following headers to ROBODoc format:
4454 lib/silccore/silcchannel.h
4455 lib/silccore/silccommand.h
4456 lib/silccore/silcid.h
4457 lib/silccore/silcidcache.h
4458 lib/silccore/silcmode.h
4459 lib/silccore/silcnotify.h
4460 lib/silccore/silcpacket.h
4461 lib/silcmath/silcmath.h
4463 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4465 * Added checking to the server code not to start the server if
4466 ciphers and stuff are not configured properly. Affected files
4467 silcd/serverconfig.[h] and silcd/server.c.
4469 * Changed the layout of the header files of the public interfaces
4470 in the SILC libraries. The new layout supports ROBODoc
4471 documentation tool (and some others) so that it is easy to create
4472 a library reference manual. All the other headers and source
4473 code must still follow the CodingStyle document. Also source
4474 code must not include these ROBODoc stuffs, only the headers.
4475 Furthermore, all public interface headers must now be named
4476 by using `silc' prefix, example: silcapi.h, silccipher.h.
4477 Some files were renamed due to this. All the other headers
4478 must not be used as public interfaces. I will update the
4479 CodingStyle document later. Changed following headers, so far:
4481 lib/silcclient/silcapi.h
4482 lib/silccore/silcauth.h
4483 lib/silccore/silcprivate.h
4484 lib/silccrypt/silcdh.h
4486 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4490 * Removed silc_client_packet_send_flush from the client library
4491 as it is not needed. Affected file lib/silcclient/client.[ch].
4493 * Added printing of message of unresolved authentication method
4494 to the Irssi SILC client. Added it to the module formats.
4495 Removed the same message from the client library.
4497 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4499 * Added new distribution feature, DISTLABEL. Every distribution
4500 can define own preprocessor label that can be used in the
4501 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
4502 file distributions, acconfig.h.pre and prepare.
4504 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4506 * Added Makefile.defines_int to include the actual definitions
4507 for Makefile.defines.in. Tested the new distribution system,
4508 created distributions and tested installation.
4510 * Added AWAY message printing to the Irssi SILC client. Added
4511 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
4513 * Added SCONNECT command to call the SILC's CONNECT command.
4514 Cannot use CONNECT directly since Irssi uses that internally.
4515 Affected file irssi/src/silc/core/silc-servers.c.
4517 Added ACTION local command. It is same as ME command but takes
4518 the channel as mandatory argument.
4520 Rewrote some of the Irssi's help files to suite for SILC
4523 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4525 * Added Makefile.defines[.in] that should for now on be included
4526 in all Makefile.am file in the source tree. That file includes
4527 all common compilation definitions for SILC source tree.
4529 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4531 * Minor changes to the ./prepare script to change the package
4532 name according the distribution name to the configure.in.
4534 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4536 * Created new distribution system. Added file `distributions'
4537 that defines all the distributions that can be created out of
4538 the SILC source tree. The ./prepare script now reads that
4539 file to determine how to prepare the distributions. The
4540 first argument to the ./prepare is the name of the distribution
4541 and second is the version of the distribution. If given
4542 without arguments it creates the default (toolkit) distribution
4543 with the default version (defined in ./prepare).
4545 All Makefile.am files that are subject to the distributions
4546 are now named as Makefile.am.pre. These are ./Makefile.am
4547 and lib/Makefile.am. Others may be changed later.
4549 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4551 * Added invite list, ban list, some key management and connection
4552 error message printing to module formats in the Irssi SILC client.
4554 * Added new silc_client_set_away_message to set the away message
4555 that is back to the person who sent private message. The
4556 affected file lib/silcclient/silcapi.h and the
4557 lib/silcclient/client_prvmsg.c.
4559 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4561 * Fixed the private message sending in the Irssi SILC client,
4562 added local command KEY to the Irssi SILC client.
4564 Added key management and key agreement message formats to the
4565 irssi/src/fe-common/silc/module-formats.[ch].
4567 Added USERS (alias WHO) printing, server/router operator
4568 indication and LIST command printing to the module formats.
4570 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4572 * Fixed channel joining notify handling, cumode notify handling
4573 from Irssi SILC client.
4575 * Added SILC specific module-formats to the Irssi SILC client so
4576 that SILC specific message hilighting, colors etc is possible.
4577 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4579 Added channel mode, channel user mode, actions, notices,
4580 whois and whowas printing to the the module-formats.c.
4582 * Fixed a bug in channel deletion in the server. The channel
4583 is not left to the cache even if the channel founder auth mode
4584 is set when there are no users anymore on the channel. Affected
4585 file silcd/server.c.
4587 * The silc_net_localhost now resolves the entire hostname including
4588 the domain name. Affected file lib/silcutil/silcnet.c.
4590 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4592 * Changed the ask_passphrase client operation to be ascynchronous.
4593 It has now a completion callback and a context that the
4594 application must call after it has got the passphrase from
4595 the user. Affected files lib/silcclient/silcapi.h,
4596 lib/silcclient/protocol.c, lib/silcclient/command.c and
4599 Added SilcAskPassphrase callback that the application calls
4600 to deliver the passphrase to the library.
4602 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4603 The public key verification and especially a certificate
4604 verification is asynchronous procedure.
4606 Added new SILC_SKE_STATUS_PENDING status to indicate the
4607 request is pending and a callback will be called to finalize
4610 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4611 indicate that remote end did not send its public key (or
4612 certificate), even though we require it. Added check for this
4613 condition in the SKE. This was a security bug, now fixed.
4615 Defined new SilcSKEVerifyCbCompletion callback that is called
4616 when the verification process is completed.
4618 The affected files lib/silcske/silcske_status.h and
4619 lib/silcske/silcske.[ch].
4621 * Changed the verify_public_key client operation to be async
4622 as well. Defined SilcVerifyPublicKey callback that is used to
4623 indicate the success of the public key verification process.
4625 Changed the server and client to use the new async client
4628 * Changed the Irssi SILC client's internal scheduler to be called
4629 twice as many times as it used to be. As a result the client
4630 should be a bit faster now. Affected file is
4631 irssi/src/silc/core/silc-core.c.
4633 * Added support to Irssi SILC client of asynchronous public key
4634 verification and passphrase inquiry. Affected file is
4635 irssi/src/silc/core/silc-core.c.
4637 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4639 * Do not say "You have left channel %s" in client library.
4640 Moved it to the application. Affected files are
4641 lib/silcclient/command.c and silc/client_ops.c.
4643 * Fixed silc_client_get_clients. Command context was not
4644 duplicated and was freed memory in the callback. Affected
4645 file lib/silcclient/idlist.c.
4647 * Do not say "you are now talking..." on JOIN command in the
4648 client library. The appliation must handle it.
4650 * Do not say ".. changed topic to" in command reply in the
4651 client libary. The application must handle it.
4653 * Fixed TOPIC command sending in the client library.
4655 * Fixed a memory leak in silc_client_command_free in the file
4656 lib/silcclient/command.c.
4658 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4660 * Imported a modified version of Irssi client to the source tree.
4661 The Irssi will be used to create a new client called
4662 Irssi SILC. Imported to irssi/.
4664 Added silc_core_init_finish function to the Irssi. Affected
4665 file irssi/configure.in.
4667 A lot changes in the Makefile.ams around the irssi tree.
4669 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4671 * Do not rehash if the new size is same as the old size of the
4672 hash table, in the silc_hash_table_rehash*. The affected file
4673 lib/silcutil/silchashtable.c.
4675 * Replaced hash_table_del_by_context calls from the server
4676 (when channel->user_list and client->channels) to the
4677 hash_table_del as it is sufficient and faster.
4679 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4681 * Added silc_hash_table_list, silc_hash_table_get and the
4682 SilcHashTableList structure to provide an alternative way to
4683 traverse the hash table. The affected files are
4684 lib/silcutil/silchashtable.[ch].
4686 * Changed the server's idlist routines to use the hash table
4687 routines to optimize the code.
4689 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4691 * Replaced the client entry's `channel' list and channel entry's
4692 `user_list' list to hash tables for optimized lookup. Changed
4693 the code to use the hash table interface around the code.
4694 Affected file lib/silcd/idlist.[ch].
4696 * Added `auto_rehash' boolean argument to the function
4697 silc_hash_table_alloc to indicate whether the hash table should
4698 auto-rehash when it thinks is appropriate time. It will
4699 increase the hash table size if the there is twice as much
4700 entries in the table than the size of the table, and will
4701 decrease the size if there are twice as less entries than
4702 the size of the table.
4704 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4706 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4708 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4710 * silc_idcache_purge_by_context deletes the entry now by context
4711 as it is supposed to do. Affected file lib/silccore/idcache.c.
4713 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4714 client is not anymore valid (WHOWAS givens the info) and not
4715 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4717 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4719 * Removed the `data' and `data_len' arguments from the ID Cache
4720 interfaces and added `name' argument. ID Cache does not handle
4721 anymore the binary data only a names associated with given ID.
4723 * When hashing a Client ID with silc_hash_id the entire ID is
4724 not hashed anymore, instead only the hash of the Client ID is
4725 hashed. This way we can access the Client ID from the cache
4726 with Client ID but with the hash of the ID (which is a hash of
4727 the nickname) as well without any difference in performance.
4729 Added also silc_idcache_find_by_id_one_ext to do one on one
4730 searching when we have the actual ID. Added also function
4731 silc_hash_client_id_compare. The affected files are
4732 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4734 * When hashing the name associated with a ID it is always done
4735 in lowercase. This way we can access the cache without worrying
4736 about case-sensitivity, even though, for example nicknames are
4739 * Fixed a bug in server with channel message sending. It put
4740 wrong ID type as destination ID. The affected file
4741 silcd/packet_send.c.
4743 * silc_idcache_del_by_context now deletes from all hash tables
4744 by context. Affected file lib/silccore/idcache.c.
4746 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4748 * Changed the client library to use the new ID Cache interface.
4749 Changes around the source tree.
4751 * Added silc_hash_table_rehash_ext to rehash with specific
4752 hash function. Affected file lib/silcutil/silchashtable.[ch].
4754 * Added silc_hash_string_compare to compare two strings in the
4755 hash table. Affected file lib/silcutil/silcutil.[ch].
4757 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4759 * Added new function silc_idcache_del_by_context into the
4760 lib/silccore/idcache.[ch].
4762 * Changed the server's ID list routines to use the new ID Cache
4763 interface. Changes around the source tree.
4765 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4767 * Added silc_hash_table_del[_by_context]_ext functions in to the
4768 lib/silcutil/silchashtable.[ch].
4770 Removed silc_hash_table_find_all* routines and added new
4771 silc_hash_table_find_foreach to replace them.
4773 Added silc_hash_table_replace_ext function as extended
4774 replacing function. Separated the simple hash table interface
4775 from the extended hash table interface in the file
4776 lib/silcutil/silchashtable.h.
4778 * Fixed minor bugs and changed it to use some of the new
4779 hash table functions in lib/silccore/idcache.c
4781 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4783 * Added new function silc_hash_table_find_all to return all keys
4784 in the hash table by the specified key. As the hash table is
4785 collision resistant it also makes it possible to have several
4786 duplicate keys in the hash table. This function may be used to
4787 find all of the keys from the hash.
4789 Added user_context arguments to the SilcHashFunction,
4790 SilcHashCompare and SilcHashDestructor to deliver user specified
4793 Added new fuctions silc_hash_table_find[_all]_ext to do
4794 extended lookup with specified hash and compare functions and
4795 specified user contexts.
4797 Added new function silc_hash_table_add_ext to add the key
4798 with specified hash function and user context.
4800 Added new function silc_hash_table_foreach to traverse all
4801 entrys in the hash table. Added SilcHashForeach callback
4804 Added new function silc_hash_table_del_by_context to delete
4805 the entry only if the context associated with the key matches.
4807 Affected files are lib/silcutil/silchashtable.[ch].
4809 * Removed silc_hash_[server/client/channel]_id and added just
4810 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4811 silc_hash_id_compare to compare two ID's using as the hash table
4812 comparison function. Added also silc_hash_data to hash
4813 binary data and silc_hash_data_compare to compare it.
4815 * Removed silc_idlist_find_client_by_hash as it is not needed
4816 anymore. Affected file silcd/idlist.[ch].
4818 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4819 to use internally the SilcHashTable. The new ID Cache is a lot
4820 faster than the old one. Some of the ID Cache interface was also
4821 rewritten and obsolete and stupid functions were removed.
4823 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4825 * Added entry_count field to the SilcHashTable to keep the number
4826 of the entries in the table. Implemented the function
4827 silc_hash_table_rehash. Added new function
4828 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4830 Fixed a minor bug in silc_hash_table_free.
4832 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4833 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4834 into the lib/silcutil/silcutil.[ch].
4836 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4838 * Implemented a collision resistant hash table into the
4839 lib/silcutil/silchashtable[ch]. See the header and the source
4840 for the SilcHashTable API.
4842 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4844 * Merged dotconf version 1.0.2 into lib/dotconf.
4846 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4848 * Do not compile anything in lib/silcsim/* if the SIM support
4849 is not enabled. The tree should now compile without problems
4852 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4854 * Compiled the SILC under cygwin. Compiled and tested briefly
4855 without problems. More tests needed. The SIMs didn't compile
4858 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4860 * Fixed possible crash in silc_get_username in the
4861 lib/silcutil/silcutil.c.
4863 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4865 * Fixed a va_arg in silc/client_ops.c.
4867 * Oops, RC5 routines were named AES and caused some problems
4868 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4870 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4872 * Added new SilcIDIP structure into the lib/silccore/id.h and
4873 replaced the old `ip' fields from all SILC ID's to that type.
4874 This is a step towards IPv6 support.
4876 The silc_id_get_len takes now the ID as an extra argument.
4877 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4878 both IPv4 and IPv6 based ID's.
4880 The affected files are lib/silccore/id.[ch] and other files
4881 around the tree using these routines.
4883 * Removed the ID length arguments in server from various
4884 silc_server_send_notify_* routines -> they are not needed
4887 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4889 * Fixed memory leak in silc_encode_pem_file in the file
4890 lib/silcutil/silcutil.c.
4892 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4894 * Check minor version as well in the SKE. Affected files are
4895 silcd/protocol.c and lib/silcclient/protocol.c.
4897 * Added --identifier option to the server so that an identifier
4898 can be when creating the public key for the server. Affected
4899 file is silcd/silcd.c.
4901 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4902 lib/silccrypt/silcpkcs.c.
4904 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4906 * Register default ciphers and stuff when using -C option with
4907 the server. Affected file sildc/silcd.c.
4909 * Put back the servers public key filename format, it is better
4910 than the new one. For now, the client keys are saved with the
4911 new filename format. The affected file silc/client_ops.c.
4913 * Implemented the Cipher API for the rest of the ciphers that
4914 did not implement it or implemented it the wrong way.
4916 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4918 * Register default ciphers and stuff when using the -S option
4919 in the client. Affected file silc/silc.c. Same also when
4920 creating new key pair with -C option.
4922 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4924 * Fixed the silc_verify_public_key client operation function to
4925 save the public keys differently. The fingerprint is now
4926 used as filename and not the hostname. This way also the
4927 client keys are saved uniquely and not with hostnames. The
4928 affected file is silc/client_ops.c.
4930 * Trimmed the silc_hash_fingerprint function to remove extra
4931 whitespaces from the end of the fingerprint. The affected
4932 file is lib/silccrypt/silchash.c.
4936 * Added silc_cipher_register_default function to register all
4937 default ciphers. It can be used when configuration files
4938 does not exist and the application does not want any specific
4939 ciphers in any specific order.
4941 The SilcDList is now used as silc_cipher_list dynamically
4942 allocated cipher list. Removed the static list all together
4943 and now all ciphers must be allocated to the dynamic list.
4944 The silc_cipher_alloc routine was changed to check only the
4947 All silc_cipher_* routines that used to return int returns
4950 The affected files lib/silccrypt/silccrypt.[ch].
4952 * The same thing was done to silc_hash_* as for silc_cipher_*
4953 routines. Affected files lib/silccrypt/silchash.[ch].
4955 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4956 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4957 Added also silc_pkcs_[un]register[_default] functions.
4958 Removed the data_context from the PKCS API.
4960 * Added silc_hmac_register_default function to register default
4961 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4962 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4963 to unregister all hmacs at once.
4965 * Register the default ciphers, hash functions, PKCSs and HMACs
4966 if client's configuration file does not exist. The affected
4969 * The client did not load the hash functions from the SIM
4970 modules at all. Added support for this. Affected file is
4971 silc/clientconfig.c.
4973 * When decoding public key with silc_pkcs_public_key_decode, check
4974 the supported algorithm only if PKCS are registered. Affected
4975 file lib/silccrypt/silcpkcs.c. The same was done with the
4976 silc_pkcs_private_key_decode.
4978 * Fixed the SILC List routines to keep the list always in order.
4979 It used to change the list's order when traversing the list but
4980 not it preserves the order. Affected file lib/trq/silclist.h.
4982 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4984 * Added the client library to use the SilcSocketConnection's
4985 reference counter (by silc_socket_dup) to prevent the bug that
4986 the socket object may be freed underneath async operation.
4988 * The name resolv library checking fixes in the configure.in.pre.
4991 * Created new version of the protocol drafts for future
4992 development. The -03 drafts are the ones that will be changed
4993 in the trunk now and the -02 will remain as they are.
4995 * Send list of CUMODE notifys to the router when announcing
4996 the channel users to the router. Affected file silcd/server.c.
4997 If the router receiving channel founder CUMODE for a channel
4998 that already has channel founder it will send CUMODE notify
4999 to the sender to remove the channel founder rights from the
5000 announced client. Affected file silcd/packet_receive.c.
5002 * The CUMODE notify may now use Server ID as well as the entity
5003 who changes the mode. Updated protocool specs.
5005 * Updated INSTALL and README files.
5007 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5009 * New web pages in the http://silc.pspt.fi. The pages was
5014 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5016 * Implemented the [DenyConnectin] config section in the server.
5017 Added silc_server_config_denied_conn to check whether incoming
5018 connection is denied. Affected file silcd/serverconfig.[ch].
5020 * Do not check the ports when checking the incoming configuration
5021 data if the port is 0, meaning any. Affected file is
5022 silcd/serverconfig.c.
5024 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5026 * Fixed buffer overflow in silc_string_compare in the file
5027 lib/silcutil/silcutil.c.
5029 * Fixed double free in silc_server_command_leave in the file
5032 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5034 * Fixed the version checking in the server. Affected file is
5037 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5039 * Fixed the configuration data fetching when accepting new
5040 connections in the server. Affected file silcd/server.c.
5042 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5044 * Added `sender_entry' argument to the function
5045 silc_server_packet_relay_to_channel so that we can check
5046 whether some destination actually belongs to the same route
5047 the sender belongs (ie, we must not resend the packet to the
5048 sender). Affected file silcd/packet_send.[ch].
5050 * Added `servername' field to the SilcClientEntry in the server
5051 to hold the name of the server where client is from. Affected
5052 file is silcd/idlist.h.
5054 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5056 * Moved the channel message encrypting in the router betwen
5057 router connections from silc_server_channel_message to the
5058 silc_server_packet_relay_to_channel since we want to check
5059 whether we have anybody channel before encrypting anything.
5060 Affected files silcd/packet_[receive/send].c.
5062 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5064 * Fixed the [AdminConnection] server config section to support
5065 multiple entries. Affected file silcd/serverconfig.c.
5067 * Added support into the server to check the validity of the
5068 incoming connection before executing any KE or authentication
5071 * The connection configuration is now saved to the KE and
5072 connection auth protocol contexts and not fetched anymore in
5073 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
5075 * The local hosts listenning address and port is also resolved
5076 now when starting the server. We want to have the socket object
5077 to include the real address and port for the listener. Added
5078 new function silc_net_check_local_by_sock into the files
5079 lib/silcutil/silcnet.[ch].
5081 * Fixed a broadcast bug in server -> do not broadcast if we
5084 * Fixed a routing bug. Do not route broadcast packets ever.
5085 Broadcast packets must be processed always and not routed since
5086 they may be destined to some other host than yourself and thus
5087 would get routed without no good reason. Affected file is
5090 * Added function silc_server_config_is_primary_route to check
5091 whether primary router connection has been configured (a router
5092 configuration that we are initiating). If there is not, we
5093 will assume that there is only two routers in the SILC network
5094 and we will use the incoming router connection as our primary
5095 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
5097 * Changed the order of the broadcasting. Broadcast _after_ the
5098 packet has been processed not before. Affected file is
5101 * Fixed a [ClientConnection] parsing bug. The port was never
5102 parsed correctly thus resulting to port 0. Affected file
5103 silcd/serverconfig.c.
5105 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
5106 argument and did not set the broadcast packet flag. Affected
5107 file silcd/packet_send.c. Fixed same bug in the function
5108 silc_server_send_notify as well.
5110 * If we receive NEW_ID packet for our own ID in the server, ignore
5113 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5117 * Removed the nickname from the Private Message Payload.
5118 Updated the code and the protocol specs.
5120 * Updated protocol specs for submitting to the IETF.
5122 * Tweaked the Random Number Generator a bit. Affected file
5123 lib/silccrypt/silcrng.c. Exported a new function
5124 silc_rng_[global]_add_noise which can be used to add more
5127 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5129 * Do not parse packets with different timeout when protocol
5130 is active -> may cause problem with rekey. Affected file
5133 * When server receives signoff notify it must not create
5134 new channel key if the client is on any channels since the
5135 sender of the signoff notify will create it.
5137 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5139 * Added printing of error messages during SKE protocol from the
5140 failure packet sent by server during SKE. Affected file
5143 * Removed the client's failure_callback handling with timeout
5144 and handle it immediately when received.
5146 * The SKE library returned wrong type in SUCCESS and FAILURE
5147 packets. They must be 32 bit MSB not 16 bit MSB.
5149 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5151 * Ok, rewrote the logic of the re-key and now it seems to work.
5152 I tested it on high traffic with frequent re-keys without
5153 problems. Added hmac_receive (and renamed hmac to hmac_send)
5154 in SilcClientConnection in lib/silcclient/client.h and
5155 in SilcIDListData in silcd/idlist.h. Also, removed the
5156 SilcPacketParserContext's cipher and hmac fields as they are
5157 not needed anymore and actually caused some problems when
5158 the ciphers and hmac's changed underneath the packet parser.
5160 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5162 * If re-key protocol is active then process the incoming packets
5163 synchronously since we must assure that icoming packets encrypted
5164 with the old key is processed before the new keys is set to
5165 use. This is true other packets than for REKEY packets.
5166 Affected file silcd/server.c. The same was done to client library
5167 as well, affected file lib/silcclient/client.c.
5169 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5171 * Fixed bug in client and server to accept the force send if
5172 the packet is send from silc_[server/client]_packet_process
5173 function. Otherwise the packets are never delivered, oops.
5175 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5177 * Disable force sending of packets when REKEY protocol is active.
5178 We must assure that no packet is sent directly when rekey is
5179 performed. All packets must be sent through packet queue.
5180 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
5181 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
5182 function is silc_[server/client]_packet_send_real to check
5185 * Replaced the SIM paths from example config files to
5186 /usr/local/modules. Also, make install creates now
5187 /usr/local/silc/logs directory to hold all the SILC server
5190 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5192 * Made the configure.in.pre work on Solaris. Patch by salo.
5194 * Made all ciphers compatible with non-x86 machines. Defined
5195 CBC mode macros into lib/silccrypt/ciphers_def.h.
5197 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5199 * Fixed the make install.
5201 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5203 * When MAC computation fails the silc_packet_decrypt returned 0
5204 even though it was supposed to return -1. Fixed this. The
5205 affected file is lib/silccore/silcpacket.c.
5207 * Do not replace the config files in /etc/silc (in make install)
5208 if they already exist. Affected file ./Makefile.am.
5210 * Do not send re-key packets immediately but through packet queue.
5211 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
5213 * Changed silc_net_check_host_by_sock to return FALSE if the
5214 IP/DNS could not be resolved. Though, it returns the IP address
5215 now even if it could not resolve it (but returns also FALSE).
5216 Affected file lib/silcutil/silcnet.[ch].
5218 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5220 * Added silc_pkcs_decode_identifier to decode the public key's
5221 identifier. Affected file lib/silccrypt/silpkcs.[ch].
5222 Added also silc_pkcs_free_identifier. Added also new context
5223 SilcPublicKeyIdentifier.
5225 * Added -S option to the silc client. It is used to dump the
5226 contents of the specified public key file.
5228 * Changed the PKCS api to return the public key length when
5229 setting the public key.
5231 * Fixed a fatal bug in the public and private key file loading.
5232 Affected file lib/silccrypt/silcpkcs.c.
5234 * Execute the packet parsing for client with zero (0) timeout
5235 if the protocol is active. Affected file silcd/server.c.
5237 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5239 * Made the key generation options to the silcd program. Added
5240 -C option, equivalent to client's option.
5242 * Added new [ServerKeys] config section to the server. It
5243 configures the server's public and private key.
5245 * Defined generic Public Key Payload into the protocol
5246 specification to send specific type of public keys and
5249 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
5250 public key or certificate.
5252 * Implemented the GETKEY command to the server and to the
5253 client library and on user interface.
5255 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5257 * Made preliminary `make install' work.
5259 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5261 * Added SilcServerRekey context into silcd/idlist.h.
5263 * Added the PFS support as defined in the specification to the
5264 SKE protocol. Affected files lib/silcske/*.c.
5266 * Added `ske_group' field to the SilcServerRekey context to hold
5267 the number of the SKE group that is used with PFS in re-key.
5268 Affected file silcd/idlist.h.
5270 * Added PFS re-key support to the server. Affected file is
5273 * Added silc_protocol_cancel to cancel execution of the next
5274 state of the protocol. Affected file is
5275 lib/silccore/silcprotocol.[ch].
5277 * Added the re-key support with and without PFS to the client
5278 library. Re-key is performed once in an hour, by default.
5280 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
5281 Added silc_client_rekey_callback and silc_client_rekey_final.
5282 Affected files are lib/silcclient/protocol.[ch] and
5283 lib/silcclient/client.[ch].
5285 * Removed the `hmac_key' and `hmac_key_len' fields from the
5286 SilcClientConnection structure; not needed. Affected file is
5287 lib/silcclient/client.h.
5291 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5293 * Do not ask whether user wants to use the negotiated private key
5294 for private messages, just use it. Affected file is
5295 silc/local_command.c.
5297 * Added `send_enc_key' and `enc_key_len' fields to the
5298 SilcIDListData structure since they are needed in the re-key
5299 phase. Affected file is silcd/idlist.[ch].
5301 * Implemented the simple re-key protocol into the server.
5302 Affected files silcd/server.c and silcd/protocol.[ch]. The
5303 re-key will be performed once in an hour, by default.
5305 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
5306 Added silc_server_rekey, silc_server_rekey_callback and
5307 silc_server_rekey_final.
5309 * Removed Tunneled flag from the protocol. Updated the code
5310 and the specifications.
5312 * Adde `pfs' field to the SilcIDListData to indicate whether
5313 the PFS is to be performed in the re-key. Affected file is
5316 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5318 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
5319 int64 of at least the xintXX size. If void * is less that 4
5320 bytes uint32 * will be used. Defined bool as boolean.
5322 * Changed _ALL_ unsigned long and unsigned int to uint32,
5323 unsgined short to uint16 in the source tree.
5325 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
5326 not handle clients that has entry->data.registered == FALSE.
5327 They are not in the network anymore. Affected file is
5330 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5332 * Implemented the sending of the SERVER_SIGNOFF notify in the
5333 server. Affected file is silcd/server.c.
5335 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
5336 Added also silc_notify_payload_encode_args into the
5337 lib/silccore/silcnotify.[ch].
5339 * Implemented ther SERVER_SIGNOFF notify handling in the server.
5340 Affected file silcd/packet_receive.c.
5342 * Implemented the SERVER_SIGNOFF notify handling in the client
5343 library. Affected file lib/silcclient/client_notify.c. Also,
5344 implemnted the printing of the SERVER_SIGNOFF info to the
5345 application. Affected file silc/client_ops.c.
5347 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
5348 if the deleting was successful. Affected file silcd/idlist.[ch].
5350 * Added support for public key authentication in the connection
5351 authentication protocol in the client library. Affected file
5352 lib/silcclient/protocol.c.
5354 * Changed the server's silc_idlist_get_clients_by_* interface
5355 to support already allocated array so that new entries may be
5356 added to pre-allocated array. Affected file silcd/idlist.[ch].
5357 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
5358 and command replies.
5360 * All command reply functions in the server now calls the
5361 pending command callback even if error occured. This way the
5362 error will be delivered to the client as well. Affected files
5363 silcd/command.c and silcd/command_reply.c.
5365 * Fixed INFO command to return local server's info if no server
5366 was provided. Affected file lib/silcclient/command.c.
5368 * Removed RESTART command for good. Updated the code and the
5371 * Rewrote parts of the task system. It is a bit simpler now.
5372 Removed unsued task priorities. The affected files are
5373 lib/silcutil/silctask.[ch].
5375 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5377 * Moved the USERS printing from the library to the application.
5378 Affected files lib/silcclient/command.c and silc/client_ops.c.
5380 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5384 * Added channel key re-key support. The re-key is perfomed
5385 only by the router and is done once in an hour. Added `rekey'
5386 field to the SilcChannelEntry in the server. Affected files
5387 silcd/server.c and silcd/idlist.h.
5389 * Added silc_task_unregister_by_context into the file
5390 lib/silcutil/silctask.[ch].
5392 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5394 * Added SILC_UMODE_GONE mode to indicate when the client is not
5395 present in the SILC network. Added also support to the local
5396 command AWAY that will set this mode. Added support of showing
5397 "xxx is gone" in WHOIS command. The USERS command shows the
5398 gone status as well.
5400 * Fixed setting server and router operator privileges in the
5401 server's UMODE command. Affected file silcd/command.c.
5403 * Merged the SKE KE1 and KE2 payloads into one payload. The
5404 new KE payload is equivalent to the old KE2 payload.
5406 Cleaned up the SKE Start Payload parsing. It now uses the
5407 simple buffer unformatting to do the parsing. A lot faster
5410 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
5411 to the SKE that is used to indicate whether both of the SKE
5412 parties should perform authentication. By default only the
5413 responder performs authentication. By setting this flag also
5414 the initiator must do authentication. By default it is unset
5415 since in normal SKE case, client to server connection, only
5416 the responder should do authentication. When doing SKE between
5417 two clients both should perform authentication. Updated the
5418 code and the protocol specs.
5420 * A little fix to IDENTIFY command in the server. Search the
5421 client first by hash not nickname. Affected file is
5424 * Fixed the silc_client_close_connection to support closing
5425 the client to client connections wihtout deleting too much
5426 data. Affected file lib/silcclient/client.c.
5428 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
5429 are received if protocol used to be active but is not anymore
5430 the application would crash due to NULL pointer dereference.
5431 Affected files silcd/server.c and lib/silcclient/client.c.
5433 * Added `hash' field to the SilcClientConnection to include
5434 the hash function negotiated in the SKE protocol.
5436 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
5437 to set the channel founder authentication data. A client can
5438 claim the founder rights later by providing the authentication
5439 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
5440 This way the channel founder can regain the channel founder
5441 privileges even it is left the channel. This works only on
5442 local server and the client must be connected to the same
5443 server to be able to regain the founder rights. Updated the
5444 protocol specs accordingly.
5446 Added support to the CMODE command in the client to set the
5447 founder auth data. Read the README to see how to set it.
5449 Added support to the CUMODE command to claim the founder
5450 rights. Read the README to see how to do it.
5452 Added support for the founder authentication to the Channel
5453 Entry in the server. Affected file silcd/idlist.h.
5455 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
5456 server's CMODE command. Affected file silcd/command.c.
5458 * Added the following new functions into lib/silccore/silcauth.[ch]:
5459 silc_auth_get_method and silc_auth_get_data.
5461 * The server now saves the remote hosts public key to the
5462 SilcIDListData pointer. Affected file silcd/protocol.c.
5464 * The normal server now does not remove the channel entry from
5465 the cache if the founder authentication data is set. It used
5466 to remove it if the founder was the last one on the channel on
5467 the server and left the channel. The auth data is saved and
5468 if the channel is re-joined later the old entry is used with
5469 the old auth data. Affected files silcd/command_reply.c and
5472 * Removed the `pkcs' field from the SilcIDListData structure
5473 in the server; it is not used. Affected file silcd/idlist.h.
5475 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5477 * Fixed packet processing on slow links. Partial packets were
5478 never re-processed because the incoming data buffer was cleared
5479 by the application. Application must not directly clear the
5480 sock->inbuf, the packet processing routines handle it. Fixed
5481 this in client library and in server.
5483 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5485 * Fixed the WHOIS and IDENTIFY send reply function to really
5486 check whether to send list or just one entry. Affected file
5489 * Cleaned up the LEAVE command's channel key distribution. The
5490 affected file silcd/command.c.
5492 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
5493 can enforce the channel mode as well. In that case the ID
5494 includes the ID of the server. The code now enforces the
5495 mode change if the router have different mode than the server.
5497 * The notify client operation with CMODE_CHANGE notify can now
5498 return NULL client_entry pointer if the CMODE was not changed
5499 by client. Application must check for this.
5501 * Added <Server ID> argument to INFO command to support server
5502 info fetching by Server ID.
5504 * Added silc_server_announce_get_channel_users to get assembled
5505 packets of channel users of the specified channel. Affected
5506 file silcd/server.[ch].
5508 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
5509 was freed underneath the ID Cache.
5511 * Re-announce clients when the server received CHANNEL_CHANGE
5512 notify from the router. Affected file silcd/packet_send.c.
5514 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5516 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
5517 crashed since it did not handle the fact that there is no cipher
5518 called "3" and didn't check the error condition. Now fixed.
5520 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
5521 flag. It can be used to send message requests.
5523 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5525 * Implemented the RESTART command in the client.
5527 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
5528 notice type messages. Added notice printing to the user
5531 * The channel keys are not re-generated if the channel's mode
5532 is PRIVKEY, ie private key on the channel exists. Affected
5533 files silcd/server.c and silcd/command.c.
5535 * Fixed a little bug in channel message delivery when channel
5536 private keys are set in the server. Affected file is
5537 silcd/packet_send.c.
5539 * Changed the setting on channel->on_channel = TRUE from the
5540 silc_client_save_channel_key to the JOIN command reply. The
5541 key payload is not received if the private channel key is set.
5542 Affected file lib/silcclient/command_reply.c and the
5543 lib/silcclient/client_channel.c.
5545 * When the CMODE_CHANGE notify is sent and the channel private
5546 key mode is removed the channel key must be re-generated in
5547 other cells as well. Added this support for the router in the
5548 silcd/packet_receive.c.
5550 * Added new local command NOTICE to send notice message on
5551 channel. Affected file silc/local_command.[ch].
5553 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5555 * Added new local command ME to the client. It is used to send
5556 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
5557 some action. Affected file silc/local_command.[ch].
5559 * Changed channel_message and private_message client operations
5560 to deliver the message flags to the application. Added also
5561 the `flags' arguments to the silc_client_send_channel_message
5562 and silc_client_send_private_message functions. Affected file
5565 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5567 * Redefined the Private Message Payload to support private message
5568 keys and to support the new private message flags. Updated
5569 the protocol specs. Flags makes it possible to have for example
5570 CTCP style messages.
5572 * Added new type SilcPrivateMessagePayload and defined an API
5573 for it in the lib/silcclient/silcprivate.[ch].
5575 * Tested private message private keys successfully. Tested the
5576 private message key set, unset and list commands with the new
5579 * Redefined the Channel Message Payload to include the channel
5580 message flags (equal with private message flags) to support
5581 for example CTCP style messages.
5583 * Defined some of the message (for channel and private message)
5584 flags. Updated the protocol specs and added the flags to the
5585 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5587 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5589 * Added SilcKeyAgreementStatus type to the key agreement routines
5590 to indicate the current status and error if one occured.
5591 The status types are defined in the lib/silcclient/silcapi.h.
5593 * Added new local command KEY that is used to set and unset private
5594 keys for channels, set and unset private keys for private messages
5595 with remote clients and to send key agreement requests and
5596 negotiate the key agreement protocol with remote client. The
5597 key agreement is supported only to negotiate private message keys,
5598 it currently cannot be used to negotiate private keys for channels,
5599 as it is not convenient for that purpose.
5601 * Fixed a minor pending callback setting bug in the function
5602 silc_client_get_client_by_id_resolve, now the function works.
5603 Affected file lib/silcclient/idlist.c.
5605 * Added function silc_net_get_local_port to get local bound
5606 port by socket. Added to lib/silcutil/silcnet.[ch].
5608 * Added `sockets' and `sockets_count' fields to the SilcClient
5609 object. They hold the sockets of the listenning sockets in
5610 the client. Listenning sockets may be for example the key
5611 agreement server. Affected file lib/silcclient/client.[ch].
5612 Added functions the silc_client_add_socket and the
5613 silc_client_del_socket. They are exported to the application
5616 * Added ~./silc/clientkeys to support other client's public keys.
5618 * Renamed verify_server_key client operation to verify_public_key
5619 and added one argument to indicate the type of the connection
5620 (server, client etc.).
5622 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5624 * Added silc_server_connection_auth_request to handle the
5625 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5626 silcd/packet_receive.[ch].
5628 * Added silc_server_send_connection_auth_request into the
5629 silcd/packet_send.c to send the connection auth request packet.
5631 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5634 * Fixed the public key authentication in responder side in the
5635 server. The `auth_data' pointer includes the SilcPublicKey
5636 not the path to the public key. Affected file silcd/protocol.c.
5638 * Implemented the public key authentication in the initiator side
5639 in the server. Affected file silcd/protocol.c.
5641 * Removed the [RedirectClient] config section from the server
5642 configuration. Is not needed and I don't want to implement it.
5644 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5646 * Cleaned up the CMODE command in the server. It now works
5647 correctly and supports all the modes defined in the protocol.
5648 Affected file is silcd/command.c.
5650 * Added `hmac_name' field to the SilcChannelEntry in the server
5651 to hold the default HMAC of the channel. It can be set when
5652 creating the channel (with JOIN command). Affected files
5655 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5656 type to indicate the change of the current cipher and hmac
5657 on the channel. Client can safely ignore the <cipher> argument
5658 (if it chooses to do so) since the CHANNEL_KEY packet will
5659 force the channel key change anyway. The <hmac> argument is
5660 important since the client is responsible of setting the new
5661 HMAC and the hmac key into use.
5663 * Fixed the CMODE command in the client library as well.
5665 * Tested CMODE command in router environment successfully.
5667 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5669 * Show the version of the remote client (or server) when connecting
5670 to the server. It is logged to the log file. Affected file
5671 is silcd/protocol.c.
5673 * Fixed the KILLED notify handling in the client library. The
5674 client must be removed from all channels when receiving the
5677 Also, do not remove the client entry when giving the KILL
5678 command but when the KILLED notify is received.
5680 * Removed silc_idlist_find_client_by_nickname from the server.
5681 Not needed anymore. Affected files silcd/idlist.[ch].
5683 * Implemented the CHANNEL_CHANGE notify type handling to the
5684 server. Affected file silcd/server.c.
5688 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5690 * Added silc_server_send_notify_invite to send the INVITE
5691 notify between routers.
5693 * Implemented the INVITE command correctly to the server.
5695 * Implemented the INVITE notify type handling in the server.
5697 * Implemented the INVITE command to the client library and on the
5700 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5702 * Added function silc_server_get_client_resolve to find the
5703 client entry by ID from all ID lists and then resolve it
5704 (using WHOIS) if it cannot be found. Affected file is
5707 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5709 * Implemented the BAN command to the client library.
5711 * The JOIN command in the server now checks the invite list
5714 * Changed the silc_command_reply_payload_encode_va and the
5715 silc_command_payload_encode_va to support that if argument is
5716 NULL it ignores and checks the next argument. Affected file
5717 lib/silccore/silccommand.c.
5719 * Added silc_server_send_notify_ban to send the BAN notify
5720 type between routers.
5722 * Chaned the silc_notify_payload_encode to support that if
5723 argument is NULL it ignores and checks the next argument.
5724 Affected file lib/silccore/silcnotify.c.
5726 * Tested ban lists in router environment successfully.
5728 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5730 * Implemented BAN command to the server, in silcd/command.[ch].
5732 * Removed the BAN and INVITE_LIST modes from the CMODE command
5735 * Added function silc_string_match to regex match two strings.
5736 Affected files lib/silcutil/silcutil.[ch].
5738 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5740 * Redefined parts of the SilcChannelEntry in the server to support
5741 the new ban and invite lists.
5743 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5745 * Redefined the INVITE command. The same command can be used to
5746 invite individuals to the channel but also to manage the invite
5747 list of the channel (to add to and remove from the invite list).
5748 Updated the protocol specs.
5750 * Added new command SILC_COMMAND_BAN that can be used to manage
5751 the ban list of the channel. Updated the protocol specs.
5753 * Removed the channel modes: the SILC_CMODE_BAN and the
5754 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5755 in the CMODE command. The equivalent features are now available
5756 using INVITE and BAN commands. Updated the protocol specs.
5758 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5759 in the network about change in the current ban list. The notify
5760 type is not used by the client.
5762 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5763 support the invite lists.
5765 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5767 * Added new function silc_string_regexify that converts string
5768 including wildcard characters into regex string that can
5769 be used by the GNU regex library. Added into the file
5770 lib/silcutil/silcutil.[ch].
5772 Added silc_string_regex_combine to combine to regex strings
5773 into one so that they can be used as one regex string by
5774 the GNU regex library. Added into the file
5775 lib/silcutil/silcutil.[ch].
5777 Added silc_string_regex_match to match two strings. It returns
5778 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5780 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5782 * Imported GNU regex to the soruce tree into lib/contrib.
5783 Fixed some compiler warning from the regex.c.
5785 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5787 * Fixed MOTD command in the server to work in router environment.
5789 * Fixed the MOTD command in the client library to support
5790 the server argument in the command.
5792 * Added `nickname_len' argument to the silc_idlist_add_client
5793 in the server, as the `nickname' argument may be binary data
5796 * Added silc_idlist_get_channels to return all channels from
5799 * Implemented LIST command to the server. Affected file is
5802 * Implemented the LIST command to the client library and on the
5805 * Added [<user count>] argument to the LIST command reply.
5806 With private channels the user count is not shown.
5808 * Updated TODO and README.
5810 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5812 * The client entry's data.registered must be TRUE even with
5813 global client entry on global client list. The data.registered
5814 is used to check whether the client is anymore in the network,
5815 for example with WHOWAS command so it must be valid.
5817 * Fixed the WHOWAS command in the server. It now actually works
5818 in router environment. Added function into silcd/command_reply.c
5819 silc_server_command_reply_whowas_save.
5821 * Added silc_idlist_purge function to the silcd/idlist.c
5822 to periodically purge the ID Cache.
5824 * Fixed INFO command in the server. It works now in router
5825 environment. Added <server name> argument to the INFO command
5826 reply. Updated the protocol specs.
5828 * Fixed minor bug in silc_idcache_purge to not purge if the
5829 expire value is zero.
5831 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5832 they were buggy because of the WHOWAS information.
5834 * Fixed local command MSG to handle the async resolving of
5835 the remote client properly. It used to fail the first MSG.
5836 Affected file silc/local_command.c.
5838 * Added `data_len' field to SilcIDCache context.
5840 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5842 * Update TODO. Todo in commands in the server.
5844 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5846 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5847 used by routers as broadcast packet to inform other routers
5848 about the changed user mode.
5850 Implemented the notify handling in the server. Affected file is
5851 silcd/packet_receive.c. Added the function
5852 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5854 * Added new generic Channel Payload and deprecated the New Channel
5855 Payload. The New Channel Payload is now the generic Channel
5858 * Added new argument `mode' to the silc_server_send_new_channel
5859 as it is required in the Channel Payload now.
5861 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5862 and created a new and real SilChannelPayload to represent the
5863 new generic Channel Payload. Implemented the encode/decode
5864 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5866 * Added silc_server_get_client_channel_list to return the list
5867 of channels the client has joined for WHOIS command reply.
5868 Affected file silcd/server.[ch].
5870 * Implemented the channel list sending in the WHOIS command reply
5871 in server and in the client.
5873 Implemented the channel list displaying on the user interface
5874 as well. Affected file silc/client_ops.c.
5876 * Added silc_channel_payload_parse_list to parse list of Channel
5877 Payloads. It returns SilcDList list of SilcChannelPayloads.
5878 Client for example can use this function to parse the list of
5879 channels it receives in the WHOIS command reply. The caller
5880 must free the list by calling silc_channel_payload_list_free.
5881 Affected files lib/silccore/silcchannel.[ch].
5883 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5885 * Added one new argument <user mode> to the WHOIS command reply
5886 to return the mode of the user in SILC. Updated the protocol
5889 Implemented it to the server and client.
5891 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5893 * Fixed the mode printing on the user interface on joining.
5894 Affected file silc/client_ops.c.
5896 * Implemented the UMODE command and user modes in general to the
5897 client library and to the user interface.
5899 * Implemented the UMODE command to the server.
5901 * The server now sends UNKNOWN_COMMAND error status if client sends
5902 unknown command. Affected file silcd/command.c.
5904 * All server commands now handle the command identifier the right
5905 way when sending the command reply to the client. The client can
5906 use to identify the command replies with the identifier.
5908 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5910 * Added silc_server_get_client_route to resolve the route to
5911 the client indicated by the client ID. Affected file is
5914 * Added silc_server_relay_packet as general function to relay
5915 packet to arbitrary destination. This deprecates functions
5916 like _send_private_message_key, _relay_notify etc. Affected
5917 file is silcd/packet_send.[ch].
5919 Removed silc_server_send_key_agreement,
5920 silc_server_send_private_message_key and
5921 silc_server_packet_relay_notify functions from the file
5922 silcd/packet_send.[ch].
5926 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5927 server. Affected file silcd/packet_receive.[ch].
5929 * Implemented the KILL command to the client. Implemented the
5930 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5931 Affected files lib/silcclient/command[_reply].c and
5932 lib/silcclient/client_notify.c. Implemented the KILL notify
5933 printing in the user inteface.
5935 * Fixed a lot silc_parse_nick memory leaks from the client
5936 library in the file lib/silcclient/command.c.
5938 * Changed the silc_server_send_notify_on_channels's `sender'
5939 argument from SilcSocketConnection to SilcClientEntry to
5940 check the sender as entry and not as connection object and not
5941 to send to the client provided as argument. The affected file
5942 is silcd/packet_send.[ch].
5944 * The notify packets that are destined directly to the client used
5945 to not to be processed by the server. Now changed that and the
5946 server processes all notify packets. After relaying the packet
5947 to the client the notify packet is processed in the server.
5949 * The silc_server_free_client_data now checks whether there is
5950 pending outgoing traffic for the client and purges the data to
5951 the network before removing the client entry.
5953 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5955 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5956 an client is killed from the SILC Network. Updated the protocol
5959 Added new function silc_server_send_notify_killed to the
5960 silcd/packet_send.[ch].
5962 * Added function silc_server_packet_relay_notify to relay notify
5963 packets that are destined directly to a client. In this case
5964 the server does not process the notify packets but merely relays
5965 it to the client. Affected file silcd/packet_send.[ch].
5967 Added also silc_server_packet_process_relay_notify to check
5968 whereto relay the notify. Affected file is
5969 silcd/packet_receive.[ch].
5971 * Implemented the KILL command to the server.
5975 * Added the backup schema desgined last fall to the protocol
5976 specs for everyone to see. The specification is in the
5977 *-spec-xx.txt draft and the packet type definitions for the
5978 backup routers is in *-pp-xx.txt draft. Thusly, added also
5979 new packet type SILC_PACKET_CELL_ROUTERS.
5981 * A big security problem in the implementation discovered. The
5982 signoff of an client did not cause new channel key generation
5983 which it of course should've done. The channel keys must be
5984 always re-generated when client leaves (or signoffs) the channel.
5985 The silc_server_remove_from_channels funtion now handles
5986 the channel key re-generation.
5988 * Added `sender' argument to the silc_server_send_notify_on_channels
5989 to not to send the client provided as argument. Affected file
5990 silcd/packet_send.[ch].
5992 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5994 * Implemented OPER and SILCOPER commands into the server and
5997 * Added silc_auth_verify and silc_auth_verify_data to verify
5998 the authentication directly from the authentication payload.
5999 It supports verifying both passphrase and public key based
6000 authentication. Affected file lib/silccore/silcauth.[ch].
6002 * Added `hash' field to the SilcIDListData structure. It is the
6003 hash negotiated in the SKE protocol. Affected file is
6006 * Slight redesigning of the SilcAuthPayload handling routines.
6007 Do not send SilcPKCS but SilcPublicKey as argument.
6009 * Implemented the public key authentication support to the
6010 serverconfig. The public key is loaded from the provided path
6011 and saved as authentication data to void * pointer. Thus,
6012 changed the unsigned char *auth_data to void *auth_data;
6014 * Fixed SHUTDOWN command to send the reply before the server
6015 is shutdown. :) Affected file silcd/command.c.
6017 * Fixed fatal bug in CONNECT command. The hostname was invalid
6018 memory and server crashed. Affected file silcd/command.c.
6020 * Fixed fatal bug in CLOSE command. The server_entry became
6021 invalid but was referenced later in the command. Affected file
6024 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6026 * Fixed fatal bug in failure packet handling. Server ignored
6027 the failure and thus crashed when it came.
6031 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6033 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
6034 that the command may be executed only once in (about) 2 seconds.
6035 The old SILC_CF_LAG flag is same but allows command bursts up
6036 to five before limiting.
6038 Added the support for CF_LAG and CF_LAG_STRICT flags to the
6039 server code. Various commands now includes the CF_LAG_STRICT
6040 flag to disallow any kind of miss-use of the command.
6042 * Fixed the silc_buffer_unformat to not to allocate any data
6043 if the length of the data is zero. It used to allocate the
6044 length + 1. Affected file lib/silcutil/silcbuffmt.c.
6046 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6048 * Changed the format of AdminConnection configuration section
6049 in the server. Added username of the admin to the format.
6050 Affected files silcd/serverconfig.[ch].
6052 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
6053 to return admin configuration data by host, username and/or
6056 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6058 * Implemented WHOWAS command to the server. Added the functions:
6060 silc_server_command_whowas_parse,
6061 silc_server_command_whowas_send_reply,
6062 silc_server_command_whowas_from_client and
6063 silc_server_command_whowas_from_server
6065 * Added <Client ID> argument to the WHOWAS command reply. Updated
6066 the protocol specs accordingly.
6068 * Implemented WHOWAS command and command_reply to the client
6071 Implemented the WHOWAS printing on the user interface.
6073 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6075 * Added new argument to the WHOWAS command reply, the real name.
6076 It is an optional argument. Updated the protocol specs.
6078 * Added SilcIDCacheDestructor callback that is registered when
6079 the SilcIDCache is allocated. The callback is called when
6080 an cache entry in the ID Cache expires, or is purged from the
6081 cache. Added into lib/silccore/idcache.[ch].
6083 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
6084 to destruct the client entries when the cache entry expires.
6085 Other ID Cache's in server and in the client library ignores
6088 * If the ID Cache entry's `expire' field is zero then the entry
6089 never expires. Added boolean `expire' argument to the
6090 silc_idcache_add function in the lib/silccore/idcache.[ch].
6091 If it is TRUE the default expiry value is used.
6093 * Added silc_server_free_client_data_timeout that is registered
6094 when client disconnects. By default for 5 minutes we preserve
6095 the client entry for history - for WHOWAS command.
6097 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6099 * Added support to the server to enforce that commands are not
6100 executed more than once in 2 seconds. If server receives
6101 commands from client more frequently, timeout is registered
6102 to process the commands. Affected file silcd/command.c.
6103 Added new function silc_server_command_process_timeout.
6105 * Changed NICK_NOTIFY handling in client library to check that
6106 if the client's nickname was changed, so there is no need to
6107 resolve anything from the server.
6109 * Removed error printing from the WHOIS and IDENTIFY commands.
6110 If error occurs then it is ignored silently in the client library.
6111 The application, however, may map the received error to
6112 human readable error string. The application currently maps
6113 the NO_SUCH_NICKNAME error to string.
6115 * Made the command status message public to the application. Moved
6116 them from lib/silcclient/command_reply.c to
6117 lib/silcclient/command_reply.h. The application can map the
6118 received command status to the string with the
6119 silc_client_command_status_message function.
6121 * Added check to the server to check that client's ID is same
6122 as the Source ID in the packet the client sent. They must
6125 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6127 * Added dist-bzip hook to the Makefile.am to make bzip2
6128 compressed distributions.
6130 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6132 * Server now enforces the maximum length for the nickname and
6133 the channel as protocol specification dictates. 128 bytes for
6134 nickname and 256 bytes for channel name.
6136 * Moved the WHOIS printing to the application. The client libary
6137 does not print out the WHOIS information anymore, the application
6138 must do it. Renamed silc_client_command_reply_whois_print to
6139 the silc_client_command_reply_whois_save.
6141 The client's idle time is also sent to the application now, and
6142 the idle is shown on screen.
6144 * Added silc_client_command_reply_identify_save to save the
6145 received IDENTIFY entries.
6147 * Do not check for channel private keys in message sending and
6148 reception if the channel does not have the PRIVKEY mode set.
6149 Affected file lib/silclient/client_channel.c.
6151 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6153 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
6154 just surfaced after chaning the JOIN procedure.
6156 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6158 * Added silc_client_get_clients_by_list to get client entries
6159 from Client ID list, that is returned for example by JOIN
6160 and USERS command replies. The application should use this
6161 function for example when JOIN command reply is received to
6162 resolve the clients already on the channel (library does not
6163 do that anymore as USERS command reply is not used in the JOIN
6164 procedure anymore). Affected files lib/silcclient/silcapi.h and
6165 lib/silcclient/idlist.c.
6167 * JOIN command reply and USERS command reply returns now SilcBuffer
6168 pointers instead of unsigned char pointers when returning
6169 the client list and mode list.
6171 * Added <Client ID> argument to the JOIN command reply, mainly
6172 for the server to identify for which client the command was
6173 originally sent. Updated protocol specs accordingly.
6175 * Added SilcDlist private_key pointer to the SilcChannelEntry
6176 in the client to support the channel private keys. Affected
6177 file is lib/silcclient/idlist.h.
6179 * Added SilcChannelPrivateKey argument to the function
6180 silc_client_send_channel_message so that application can choose
6181 to use specific private ke if it wants to. If it is not provided,
6182 the normal channel key is used, unless private keys are set.
6183 In this case the first (key that was added first) is used
6184 as the encryption key.
6186 * Implemented the support for channel private key handling.
6187 Implemented the following functions:
6189 silc_client_add_channel_private_key,
6190 silc_client_del_channel_private_keys,
6191 silc_client_del_channel_private_key,
6192 silc_client_list_channel_private_keys and
6193 silc_client_free_channel_private_keys
6195 Affected file lib/silcclient/client_channel.c.
6197 * Added the support for the private keys in the channel message
6198 sending and encryption and in the message reception and
6199 decryption. Affected funtions are
6200 silc_client_send_channel_message and silc_client_channel_message.
6202 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6204 * Added SKE's key verify callback to the client library's
6205 KE protocol context. Affected files lib/silcclient/protocol.[ch].
6207 * Removed the statement that server (or router) must send USERS
6208 command reply when joining to the channel so that the client
6209 knows who are on the channel. Instead, the client list and
6210 client's mode list is now sent in the JOIN command reply to the
6211 client who joined channel. This is better solution.
6213 * Added function silc_server_get_users_on_channel and function
6214 silc_server_save_users_on_channel to the silcd/server.[ch].
6216 * Removed function silc_server_command_send_users from the
6219 * Do not show topic on the client library anymore. The topic is
6220 sent in the command reply notify to the application and the
6221 application must show the topic now.
6223 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6225 * Added client searching by nickname hash into the IDENTIFY and
6226 WHOIS commands in the server as they were clearly missing from
6227 them. Affected file is silcd/command.c.
6229 * Fixed a bug in private message receiving in the client library.
6230 The remote ID was freed and it wasn't supposed, now it is
6233 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6235 * Minor fix to the channel payload; allocate the data area, as it
6236 needs to be of specific length.
6238 * If the key agreement port is zero then the operating
6239 system will define the bound port. Affected files are
6240 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
6242 * Added new function silc_channel_payload_decrypt into the file
6243 lib/silccore/silcchannel.[ch].
6245 * Moved the channel message etc, check from silc_packet_decrypt
6246 to applications. The library calls now a generic
6247 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
6248 when the packet is either normal or special. This was done to
6249 allow more wide range of checking that was not allowed when
6250 the code was in library. Now applications can do virtually any
6251 checks to the packet and return to the library the decision how
6252 the packet should be processed. Affected files are
6253 lib/silccore/silcpacket.[ch].
6255 Added silc_server_packet_decrypt_check to the server and
6256 silc_client_packet_decrypt_check to the client library.
6258 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
6259 to send with specified source and destination information.
6261 * Channel message delivery between routers was broken after the
6262 channel key distribution was fixed earlier. The channel key
6263 was used be to distributed to other routers as well which is not
6264 allowed by the protocol. Now this is fixed and channel keys
6265 really are cell specific and the channel message delivery between
6266 routers comply with the protocol specification.
6268 * Fixed various commands in server to check also the global list
6269 for the channel entry and not just the local list. The affected
6270 file silcd/command.c.
6272 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6274 * Added assert()s to buffer formatting and unformatting routines
6275 to assert (if --enable-debug) when error occurs. Affected
6276 file: lib/silcutil/silcbuffmt.c.
6278 * Changed to auto-reconnect to check whether the remote host is
6279 router and register the re-connect timeout if it is. It used
6280 to check that whether we are normal server, but router must do
6281 auto-reconnect with another router as well. Affected file
6284 * Removed the [<key len>] option from CMODE command as the cipher
6285 name decides the key length, nowadays. See the defined ciphers
6286 from the protocol specification.
6288 * Added [<hmac>] option to the CMODE command to define the HMAC
6289 for the channel. Added SILC_CMODE_HMAC channel mode.
6291 * Added [<hmac>] option for the JOIN command so that user can
6292 select which HMAC is used to compute the MACs of the channel
6295 * Added Hmac field to the Channel Message Payload. The integrity
6296 of plaintext channel messages are now protected by computing
6297 MAC of the message and attaching the MAC to the payload. The
6298 MAC is encrypted. Now, it is clear that this causes some
6299 overhead to the size of the packet but rationale for this is that
6300 now the receiver can verify whether the channel message decrypted
6301 correctly and also when private keys are set for the channel the
6302 receiver can decrypt the packet with several keys and check from
6303 the MAC which key decrypted the message correctly.
6305 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
6306 lib/silccrypt/silccipher.[ch].
6308 * Added silc_hash_len to return the digest length into the
6309 lib/silcrypt/silchash.[ch].
6311 * Rewrote parts of Silc Channel Payload interface in the
6312 lib/silccore/silcchannel.[ch]. The encode function now also
6313 encrypts the packet and parse function decrypts it.
6315 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6317 * Fixed a minor formatting bug in the SKE's key material processing.
6318 It actually might have processed the keys wrong way resulting
6321 * Redefined the mandatory HMAC algorithms and added new algorithms.
6322 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
6323 and hmac-md5 truncated to 96 bits. The mandatory is now
6324 hmac-sha1-96. Rest are optional (including the one that used
6325 to be mandatory). Rationale for this is that the truncated HMAC
6326 length is sufficient from security point of view and can actually
6327 make the attack against the HMAC harder. Also, the truncated
6328 HMAC causes less overhead to the packets. See the RFC2104 for
6331 * Added new [hmac] configuration section. The SKE used to use
6332 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
6333 is of course wrong. The official names that must be proposed in
6334 the SKE are the ones defined in the protocol specification
6335 (hmac-sha1-96 for example). The user can configure any hmac
6336 using any hash function configured in the [hash] section. At
6337 least, the mandatory must be configured.
6339 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
6341 * Added HMAC list to the SKE proposal list. It has now both
6342 hash algorithm list and HMAC list. This makes the protocol
6343 incompatible with previous versions. The SKE now seems to work
6344 the way it is supposed to work, for the first time actually.
6346 * Defined plain Hash algorithms to the protocol specification.
6349 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6351 * Implemented support for key agreement packets into the server.
6352 Added functions silc_server_key_agreement and
6353 silc_server_send_key_agreement. Other than these functions,
6354 server has nothing to do with this packet.
6356 * Added support for private message key packets into the server.
6357 Added functions silc_server_private_message_key and
6358 silc_server_send_private_message_key.
6362 * Changed the silc_[client|server]_protocol_ke_set_keys to be
6363 called in the protocol's final callback instead in the END
6364 protocol state. This makes a little more sense and in the same
6365 time in client we can use the same protocol routines for normal
6366 key exchange and to key agreement packet handling as well.
6368 * Added to both client's and server's KE protocol context the
6369 SilcSKEKeyMaterial pointer to save the key material. We will
6370 bring the key material to the protocol's final callback by doing
6371 this. The final callback must free the key material.
6373 * Added SKE's packet_send callback into client's KE protocol
6374 context so that the caller can choose what packet sending function
6375 is used. This way we can use different packet sending when
6376 doing normal SKE when doing key agreement packet handling (in
6377 the key agreement packet handling we do not want to encrypt
6380 * Implemented the responder side of the key agreement routines
6381 in the client. The client can now bind to specified port and
6382 accept incoming key negotiation. The key material is passed
6383 to the application after the protocol is over.
6385 * Implemented the processing of incoming Key Agreement packet
6386 in the client. Added function silc_client_key_agreement to
6389 * Implemented the intiator side of the key agreement routines
6390 in the client. The client can now initiate key agreement with
6391 another remote client. The key material is passed to the
6392 application after the protocol is over.
6394 * Created client_keyagr.c to include all the key agreement
6397 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
6398 SILC_TASK_CALLBACK except that it is not static.
6400 * Created client_notify.c and moved the Notify packet handling
6401 from the client.[ch] into that file.
6403 * Created client_prvmsg.c and moved all private message and
6404 private message key routines from the client.[ch] into that file.
6406 * Create client_channel.c and moved all channel message and
6407 channel private key routines from the client.[ch] into that file.
6409 * Changed silc_client_get_client_by_id_resolve to resolve with
6410 WHOIS command instead of IDENTIFY command, in the file
6411 lib/silclient/idlist.c.
6413 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6415 * Implemented the SKE's responder side to the Client library.
6417 * When FAILURE is received to the protocol do not trust it
6418 blindly. Register a timeout to wait whether the remote closes
6419 the connection as it should do it, only after that process the
6420 actual failure. This was changed to both client and server.
6422 * Added client_internal.h to include some of the structures
6423 there instead of client.h in lib/silcclient/.
6425 * Added function silc_task_unregister_by_callback to unregister
6426 timeouts by the callback function.
6428 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6430 * Some "Incomplete WHOIS info" errors has been appearing on the
6431 log files. Took away the entry->userinfo check from WHOIS
6432 reply sending. The entry->userinfo is now " " if client did not
6433 provide one. I thought this was fixed earlier but something
6434 is wrong still. Let's see if the error still appears.
6436 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6438 * Fixed a minor bug in the login when the channel key is
6439 re-generated in the server. It used to generate the key in
6440 wrong order and thus caused problems in the channel traffic.
6442 * Fixed a minor bug in channel key distsribution after
6443 KICK command. The key was not sent to the router even though
6446 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6448 * Added silc_ske_process_key_material_data as generic routine
6449 to process any key material as the SILC protocol dictates. The
6450 function is used by the actual SKE library but can be used by
6451 applications as well. This relates to the private message keys
6452 and the channel private keys since they must be processed the
6453 same way the normal SILC session keys. The protocol dictates
6454 this. Affected files: lib/silcske/silcske.[ch].
6456 Added also silc_ske_free_key_material to free the
6457 SilcSKEKeyMaterial structure.
6459 * Defined silc_cipher_set_key function to set the key for
6460 cipher without using the object's method function. The affected
6461 files: lib/silccrypt/silccipher.[ch].
6463 * Implemented silc silc_client_add_private_message_key,
6464 silc_client_add_private_message_key_ske,
6465 silc_client_del_private_message_key,
6466 silc_client_list_private_message_keys and
6467 silc_client_free_private_message_keys functions in the
6470 Added functions silc_client_send_private_message_key to send
6471 the Private Message Key payload and silc_client_private_message_key
6472 to handle incoming Private Message Key payload.
6474 * Added Cipher field to the Private Message Key payload to set
6475 the cipher to be used. If ignored, the default cipher defined
6476 in the SILC protocol (aes-256-cbc) is used.
6478 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6480 * Removed lib/silcclient/ops.h file.
6482 Redefined parts of the SILC Client Library API. Created new
6483 file silcapi.h that deprecates the ops.h file and defines the
6484 published Client Library API. Defined also private message key
6485 API and channel private key API into the file.
6487 This is the file that the application must include from the
6488 SILC Client Library. Other files need not be included by
6489 the application anymore.
6491 * Added new key_agreement client operation callback and also
6492 defined the Key Agreement library API for the application.
6494 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6496 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
6497 is used by clients to request key negotiation between another
6498 client in the SILC network. If the negotiation is started it
6499 is performed using the SKE protocol. The result of the
6500 negotiation, the secret key material, can be used for example
6501 as private message key.
6503 Implemented the Key Agreement payload into the files
6504 lib/silccore/silauth.[ch].
6506 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6508 * Redefined ciphers for the SILC protocol. Added some new ciphers
6509 and defined the key lengths for the algorithms. Changed the
6510 code accordingly. The default key length is now 256 bits.
6512 * Fixed SKE key distribution function silc_ske_process_key_material
6513 when the key length is more than 128 bits. The default key
6514 length in SILC is now 256 bits.
6516 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
6517 to indicate unsupported algorithm.
6519 * Renamed rijndael.c to aes.c and all functions as well.
6521 * Fixed a long standing channel key setting bug in client library.
6522 Weird that it has never surfaced before.
6524 * Fixed bug in channel deletion. If the entire channel is removed
6525 then it must also delete the references of the channel entry
6526 from the client's channel list as the client's channel entry and
6527 the channel's client entry share same memory.
6529 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6531 * Implemented CONNECT and SHUTDOWN commands in the client.
6533 * Implemented CLOSE command to the client.
6535 * Added the function silc_idlist_find_server_by_name into the
6536 files silcd/idlist.[ch].
6538 Added the function silc_idlist_find_server_by_conn into the
6539 files silcd/idlist.[ch].
6541 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6543 * DIE command was renamed to SHUTDOWN. Updated the both code
6546 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
6547 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
6549 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
6552 * Added function silc_server_create_connection function to create
6553 connection to remote router. My server implementation actually
6554 does not allow router to connect to normal server (it expects
6555 that normal server always initiates the connection to the router)
6556 so the CONNECT command is only good for connecting to another
6559 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6561 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
6562 or some other client was kicked from the channel.
6564 Implemented the handling of the notify type to both client
6567 Implemented silc_server_send_notify_kicked to send the KICKED
6568 notify. It is used to send it to the server's primary router.
6570 * Implemented the KICK command into server and client.
6572 * Added `query' argument to the silc_idlist_get_client function
6573 to indicate whether to query the client from server or not if
6576 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
6577 to indicate that the client is not channel founder.
6581 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6583 * Removed the rng context from SilcPacketContext structure and
6584 changed that the packet routine uses the Global RNG API.
6586 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6588 * Added support for quit message that client can "leave" on the
6589 channel when it quits the SILC. It is ditributed inside the
6590 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6592 Added silc_server_free_client_data that will take the
6593 signoff message as argument.
6595 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6597 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6599 * Updated parts of the protocol specification to keep it up
6602 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6604 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6605 payloads in one packet.
6607 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6608 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6609 use now the new List flag.
6611 * Also deprecated the following packet types: REPLACE_ID,
6612 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6614 * Added list support for Notify packet in server.
6616 * Added silc_server_send_notify_channel_change to send the
6617 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6618 the silc_server_send_replace_id.
6620 * Added silc_server_send_notify_nick_change to send the
6621 NICK_CHANGE notify type. Deprecates the function
6622 silc_server_send_replace_id.
6624 * Added silc_server_send_notify_join to send the JOIN notify type.
6625 Deprecates the function silc_server_send_new_channel_user.
6627 * Added silc_server_send_notify_leave to send LEAVE notify type.
6628 Deprecates the function silc_server_send_remove_channel_user.
6630 * Added silc_server_send_notify_cmode and
6631 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6632 types. Deprecates the silc_server_send_set_mode function.
6634 * Added SERVER_SIGNOFF notify type to indicate that server has
6635 quit. This means that all clients on the channel from that
6636 server will drop. This can be also used when netsplit happens.
6638 Deprecated REMOVE_ID packet type since it is not needed anymore
6641 Added silc_server_send_notify_server_signoff to send the
6642 SERVER_SIGNOFF notify type. Deprecates the function
6643 silc_server_send_remove_id.
6645 Added also silc_server_send_notify_signoff to send the
6646 SIGNOFF notify type.
6648 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6649 SILC protocol from this day on. Changed the protocol
6650 specification as well.
6652 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6653 notify type. It is used between routers to notify about
6654 topic changes on a channel.
6656 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6659 * Partly updated the protocol specification to comply with the
6660 changes now made. It is still though a bit outdated.
6662 * The JOIN notify type now takes one extra argument <Channel ID>.
6663 The packet used to be destined to the channel but now the
6664 JOIN type may be sent as list thus it is impossible to
6665 destine it to any specific channel. By adding this argument
6666 it is again possible.
6668 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6670 * Added CREDITS file. The CHANGES and CREDITS file will appear
6671 in the distribution as well.
6673 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6675 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6676 types in the server's silcd/packet_receive.c.
6678 * Implemented CMODE and CUMODE to work in router environment.
6680 * Fixed minor encoding and decoding buglet from the
6681 lib/silccore/silcmode.c.
6683 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6686 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6688 * Changed all SilcConfigServer* and silc_config_server* to
6689 SilcServerConfig* and silc_server_config*, respectively.
6692 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6694 * Associated the ID (client or server ID) to the Authentication
6695 Payload to avoid any possibility of forging. Updated the
6696 protocol specification and the code accordingly.
6698 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6700 * The RSA key length is now save to the RsaKey context in the
6701 key generation process in lib/silccrypt/rsa.c. The key length
6702 is now used to figure out the maximum size of the block allowed
6703 to be encrypted/signed.
6705 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6706 is equivalent to the silc_mp_mp2bin but does not allocate any
6709 * Changed silc_mp_mp2bin API to take length argument. If it is
6710 non-zero then the buffer is allocated that large. If zero, then
6711 the size is approximated using silc_mp_sizeinbase, which however
6714 * Created Global RNG API which is global RNG that application can
6715 initialize. After initializing, any routine anywhere in the
6716 code (including library) can use RNG without allocating a new
6717 RNG object. This was done to allow this sort of use of the
6718 RNG in code that has no chance to allocate RNG object. All
6719 applications currently allocate this and many routines in the
6720 library use this. Affected file lib/silccrypt/silcrng.[ch].
6722 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6723 it to use the Global RNG API.
6725 * Defined Authentication Payload into protocol specification that
6726 is used during SILC session to authenticate entities. It is
6727 used for example by client to authenticate itself to the server
6728 to obtain server operator privileges.
6730 Implemented this payload into the lib/silccore/silcauth.[ch].
6731 Implemented also routines for public key based authentication
6732 as the new protocol specification dictates.
6734 Moved definitions of different authentication methods from
6735 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6737 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6738 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6739 silc_pkcs_verify_with_hash functions into the file
6740 lib/silccrypt/silcpkcs.[ch].
6742 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6744 * The client entry's userinfo pointer must be always valid.
6745 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6746 will fail since it requires the userinfo. Now, the userinfo
6747 is allocated as "" if actual userinfo does not exist. Actually,
6748 it must exist and it is totally Ok to drop client connections
6749 that does not announce the userinfo. However, we will make
6750 this workaround for now.
6752 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6753 to return the remote port by socket.
6755 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6757 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6758 SILC_SERVER_PENDING_EXEC and added an new macro
6759 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6760 data or when error occurs while processing the pending command.
6762 Added new argument `destructor' into silc_server_command_pending
6763 and to the SilcServerCommandPending object. This destructor is
6764 now called after calling the pending callback or if error occurs
6765 immediately. If error occurs the actual pending callback won't
6766 be called at all - only the destructor. The destructor may be
6767 NULL if destructor is not needed.
6769 All this applies for client library code as well. Similar
6770 changes were made there as well for the pending commands.
6772 In the client, the application must now allocate the
6773 SilcClientCommandContext with the silc_client_command_alloc
6776 * Added reference counter to the SilcServerCommandContext. Added
6777 function silc_server_command_alloc and silc_server_command_dup
6780 Same type of functions added to the client library for the same
6783 * Removed the cmd_ident from IDListData away since it is now
6784 global for all connections. It is the command identifier used
6785 in command sending and with pending commands. The affected file
6788 * Added reference counter to the SilcSocketConnection objecet to
6789 indicate the usage count of the object. The object won't be
6790 freed untill the reference counter hits zero. Currently only
6791 server uses this, and client ignores it. The client must be
6792 set to use this too later. The affected files are
6793 lib/silccore/silcsockconn.[ch]. Added also the function
6794 silc_socket_dup to increase the reference counter.
6796 This was mainly added because it is possible that the socket
6797 is removed underneath of pending command or other async
6798 operation. Now it won't be free'd and proper DISCONNECTING
6799 flags, etc. can be set to avoid sending data to connection that
6800 is not valid anymore.
6802 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6803 the connection. After that it sets SILC_SET_DISCONNECTED.
6804 It is, however, possible that the socket data is not still freed.
6805 The silc_server_packet_process now checks that data is not
6806 read or written to connection that is DISCONNECTED. The socket
6807 get's freed when the reference counter hits zero.
6809 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6811 * Changed the client operation API: channel_message operation's
6812 `sender' is now the client entry of the sender, not the nickname
6813 and the `channel' is the channel entry, not the channel name.
6815 In the private_message operation the `sender' is now also the
6816 client entry of the sender not the nickname.
6818 Affected file is lib/silcclient/ops.h and all applications
6819 using the client operations.
6821 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6823 * Moved the calling of ops->connect() from connect_to_server_final
6824 into receive_new_id functin since that is the point when the
6825 client is actually allowed to send traffic to network. The
6826 affected file is lib/silcclient/client.c.
6828 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6830 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6831 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6832 (if needs broadcasting) instead of broadcasting the packets one
6833 by one which would make a burst in the network traffic.
6835 * Added `broadcast' argument to the functions in silcd/server.[ch]
6836 silc_server_create_new_channel[_with_id] to indicate whether
6837 to send New Channel packet to primary router.
6839 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6841 * Added new function into the silcd/server.[ch] files:
6842 silc_server_create_new_channel_with_id to create new channel with
6843 already existing Channel ID.
6845 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6846 lib/silccore/silcpacket.h. This packet is used t send list of
6847 Set Mode payloads inside one packet. Server uses this to set
6848 the modes for the channels and clients on those channels, that it
6849 announced to the router when it connected to it. The protocol
6850 specification has been updated accordingly.
6852 * The silc_server_new_channel did not handle the packet coming
6853 from normal server as it normally does not send that. However,
6854 when it announces its channels it does send it. Implemented
6855 the support for that.
6857 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6858 into the file lib/silccore/id.h.
6860 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6862 * Fixed memory leaks in the functions silc_idlist_del_client,
6863 silc_idlist_del_channel and silc_idlist_del_server in the file
6864 silcd/idlist.c. All of those leaked like a sieve.
6866 * Fixed some small memory leaks in the client's function
6867 silc_client_notify_by_server.
6869 * Added functions into silcd/server.c: silc_server_announce_clients,
6870 silc_server_announce_channels and silc_server_announce_server.
6871 These functions are used by normal and router server to announce
6872 to its primary router about clients, channels and servers (when
6873 router) that we own. This is done after we've connected to the
6876 These functions effectively implements the following packet types:
6877 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6878 and SILC_PACKET_NEW_ID_LIST.
6880 * Added new functions into the silcd/packet_receive.[ch]:
6881 silc_server_new_id_list, silc_server_new_channel_list and
6882 silc_server_new_channel_user_list to handle the incoming
6883 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6885 * Added support of changing Channel ID in the function
6886 silc_server_replace_id. If the server that announces a channel
6887 to the router already exists in the router (with same name but
6888 with different Channel ID), router is responsible to send
6889 Replace ID packet to the server and force the server to change
6890 the Channel ID to the one router has.
6892 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6893 client that the Channel ID has been changed by the router. The
6894 normal server sends this to the client. Client must start using
6895 the new Channel ID as the channel's ID.
6897 Implemented handling of this new type into lib/silcclient/client.c
6898 into the function silc_client_notify_by_server.
6900 * Added new function silc_idlist_replace_channel_id into the files
6901 silcd/idlist.[ch] to replace the Channel ID.
6903 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6905 * Call silc_server_command_identify_check always when processing
6906 the IDENTIFY command in silcd/command.c
6908 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6910 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6911 send keepalive packets. The packet can be sent by clients,
6912 servers and routers.
6914 Added function silc_socket_set_heartbeat into the file
6915 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6916 If not set, the heartbeat is not performed. The actual
6917 heartbeat is implemented in the low level socket connection
6918 library. However, application is responsible of actually
6921 Added silc_server_send_heartbeat to send the actual heartbeat
6922 packet into silcd/packet_send.[ch]. Server now performs
6923 keepalive with all connections.
6925 * Added silc_task_get_first function into lib/silcutil/silctask.c
6926 to return the timeout task with shortest timeout. There was a bug
6927 in task unregistration that caused problems. TODO has been
6928 updated to include that task system must be rewritten.
6930 * The client library will now resolve the client information when
6931 receiving JOIN notify from server for client that we know but
6932 have incomplete information.
6934 * Rewrote parts of silc_server_remove_from_channels and
6935 silc_server_remove_from_one_channel as they did not remove the
6936 channel in some circumstances even though they should've.
6938 * Encryption problem encountered in server:
6940 The LEAVE command used to send the Channel Key packet to the
6941 router immediately after generating it. However, the code
6942 had earlier sent Remove Channel user packet but not immediately,
6943 ie. it was put to queue. The order of packets in the router
6944 was that Channel Key packet was first and Remove Channel User
6945 packet was second, even though they were encrypted in the
6946 reverse order. For this reason, MAC check failed. Now, this
6947 is fixed by not sending the Channel Key packet immediately but
6948 putting it to queue. However, this is more fundamental problem:
6949 packets that are in queue should actually not be encrypted
6950 because packets that are sent immediately gets encrypted
6951 actually with wrong IV (and thus MAC check fails). So, packets
6952 that are in queue should be encrypted when they are sent to
6953 the wire and not when they put to the queue.
6955 However, the problem is that the current system has not been
6956 designed to work that way. Instead, the packet is encrypted
6957 as soon as possible and left to the queue. The queue is then
6958 just purged into wire. There won't be any fixes for this
6959 any time soon. So, the current semantic for packet sending
6962 o If you send packet to remote host and do not force the send
6963 (the packet will be in queue) then all subsequent packets to the
6964 same remote host must also be put to the queue. Only after the
6965 queue has been purged is it safe again to force the packet
6968 o If you send all packets immediately then it safe to send
6969 any of subsequent packets through the queue, however, after
6970 the first packet is put to queue then any subsequent packets
6971 must also be put to the queue.
6973 Follow these rules and everything works fine.
6975 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6977 * Added new function silc_server_remove_clients_by_server to
6978 remove all client entries from ID list when the server connection
6979 is lost. In this case it is also important to invalidate all
6980 client entires as they hold the invalid server entry. This
6981 fixes fatal bug when server has lost connection and will reconnect
6984 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6986 * Made some sanity checks to silc_server_daemonise like to check
6987 whether the requested user and group actually exists.
6989 * Added sanity check to SKE's silc_ske_responder_finish to check
6990 that the public and private key actually is valid.
6992 * Invalidate the client's nickname when receiving Replace ID
6993 packet and the Client ID is being replaced. This means that the
6994 server will query the nickname if someone needs it (client)
6997 * Sort the ID Cache in client library when the ID Cache data
6998 has changed (needs sorting).
7000 * Do not allow for SILC client to create several connections to
7001 several servers. The client does not support windows right now
7002 and generating multiple connections causes weird behaviour.
7004 Irssi-silc client does support windows and can handle several
7005 connections without problems, see: www.irssi.org and SILC plugin.
7007 * Fixed some places where client was added to the IDList. The
7008 rule of thumb is following (in order to get everything right):
7009 If the client is directly connected local client then the
7010 `connection' argument must be set and `router' argument must be
7011 NULL to silc_idlist_add_client function. If the client is not
7012 directly connected client then the `router' argument must
7013 bet set and the `connection' argument must be NULL to the
7014 silc_idlist_add_client function.
7016 * The funtion silc_server_packet_send_local_channel actually did
7017 not check whether the client was locally connected or not. It
7018 does that now. Fixed a bug related to LEAVE command.
7020 * Fixed Remove Channel User payload parsing bug in server's
7021 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
7023 * The server's silc_server_save_channel_key now checks also the
7024 global ID list for the channel as it might not be in the local
7025 list. Fixed a bug related to LEAVE command.
7027 * Is this the end of the [<unknown>] buglet that has been lurking
7028 around for a long time? A little for loop fix in server's
7029 silc_server_command_whois_parse that is used by both IDENTIFY
7030 and WHOIS command. At least, this was a clear bug and a cause
7031 of one type of [<unknown>] buglet.
7033 * WHOIS and IDENTIFY commands call the function
7034 silc_server_command_[whois/identify]_check function even if
7035 we are not router server.
7037 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7039 * Added --with-gmp configuration option. If set the GMP
7040 is always compiled in the SILC source tree. If not set then
7041 it is checked whether the system has the GMP3 installed. If
7042 it has then the GMP won't be compiled (the system's headers
7043 and library is used), if it doesn't have it then the GMP is
7044 compiled in the SILC source tree.
7046 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7048 * Changed RSA private exponent generation to what PKCS #1
7049 suggests. We try to find the smallest possible d by doing
7050 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
7051 not security fix but optimization.
7053 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7055 * Added new config entry [Identity] to fork the server and run
7056 it as specific user and group. A patch from Bostik.
7058 * Imported Dotconf configuration library into lib/dotconf.
7059 This will be used to create the SILC configuration files later.
7060 It will appear in the distsribution after this commit.
7062 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7064 * A big code auditing weekend happening. Auditing code for
7065 obvious mistakes, bugs and errors. Also, removing any code
7068 Removed files for being obsolete:
7070 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
7071 inline in the file lib/silcutil/silcbuffer.h)
7073 o lib/silcutil/silcbufutil.c (the header has inline versions)
7075 Changed code to fix possible error conditions:
7077 o The buffer formatting routines now check that the destination
7078 buffer really has enough space to add the data. This applies for
7079 both buffer formatting and unformatting
7080 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
7081 unformatting was changed to accomodate following rules:
7082 XXX_*STRING_ALLOC will allocate space for the data into the pointer
7083 sent to the function while XXX_*STRING will not allocate or copy
7084 the data into the buffer. Instead it sets the pointer from the
7085 buffer into the pointer sent as argument (XXX_*STRING used to
7086 require that the pointer must be allocated already). This change
7087 makes this whole thing a bit more consistent and more optimized
7088 (note that the data returned in the unformatting with XXX_*STRING
7089 must not be freed now). The routines return now -1 on error.
7091 o Tried to find all code that use buffer_format and buffer_unformat
7092 and added return value checking to prevent formatting and
7093 especially unformatting errors and possible subsequent fatal
7096 o Changed ske->x and ske->KEY to mallocated pointers in
7097 lib/silcske/silcske.h. Fixed possible data and memory leak.
7099 o Added return value checking to all *_parse* functions. Fixed
7100 many memory leaks as well.
7102 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
7103 so that buffer overflows would not happen. All code now also
7104 checks the return value as it can fail.
7106 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7108 * Added reconnection support to server if the normal server looses
7109 its connection to the router (for example if router is rebooted).
7110 The server performs normal reconnection strategy implemented
7111 to the server. Affected file silcd/server.c.
7113 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7115 * Added new packet type SILC_PACKET_SET_MODE that is used to
7116 distribute the information about changed modes (for clients,
7117 channels and clients channel modes) to all routers in the
7118 network. Updated the protocol specification accordingly.
7120 Added functions into silcd/packet_send.c and
7121 silcd/packet_receive.c: silc_server_send_set_mode,
7122 silc_server_set_mode.
7124 Added new files silcmode.[ch] into lib/silccore that implements
7125 the encoding and decoding of Set Mode Payload. Added new type
7126 SilcSetModePayload. Moved the definitions of different modes
7127 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
7129 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7131 * Oops, a little mistake in server's connection authentication
7132 protocol. The protocol is not ended with FAILURE but with
7133 SUCCESS if the authentication is Ok. :) Affected file is
7136 * Implemented NICK_CHANGE notify handling in server in the file
7137 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
7138 the local clients on the channel. After the changing nickname
7139 in router environment snhould work and the [<unknown>] nickname
7140 should appear no more.
7142 The silc_server_replace_id function that receives the Replace ID
7143 payload now sends the NICK_CHANGE notify type also in the file
7144 silcd/packet_receive.c
7146 * Changed WHOIS and IDENTIFY command to support the maximum amount
7147 of arguments defined in protocol specs (3328 arguments). This
7148 fixed a bug that caused problems when there were more than three
7151 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7153 * Added extra parameter, command identifier, to the
7154 silc_client_send_command so that explicit command identifier
7157 Changed that ID list routines uses specific command identifier
7158 when sending WHOIS/IDENTIFY requests to the server so that they
7159 can be identified when the reply comes back.
7161 Affected files lib/silcclient/command.[ch],
7162 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
7164 * Added `sender' argument to silc_server_packet_send_to_channel
7165 to indicaet the sender who originally sent the packet to us
7166 that we are now re-sending. Ignored if NULL. Affected file
7167 silcd/packet_send.[ch].
7169 * Added some server statistics support in silcd/server_internal.h
7170 SilcServerStatistics structure and around the server code. Also
7171 send some nice statistics information when client is connecting
7174 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7176 * Fixed channel ID decoding in server's JOIN command reply in
7177 silcd/command_reply.c
7179 * Fixed braodcasting of replace ID payload to not to send it if
7180 we are standalone server in silcd/packet_receive.c.
7182 * Fixed all channel message sending routines to not to send
7183 packets to clients that has router set, since they are routed
7184 separately in the same function earlier. Affects file
7185 silcd/packet_send.c and all channel packet sending functions.
7187 * In USERS reply, res_argv[i] are not allocated, the table
7188 is allocated. Thus changed that free the table, not its
7191 * In server's whois_check and identify_check if the client is
7192 locally connected do not send any WHOIS commands - they are not
7195 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7197 * Fixed some minor bugs in client when sending WHOIS command. The
7198 arguments was in wrong order.
7200 * Removed statis function add_to_channel from server in
7201 silcd/command.c that was previously used with the joining but
7204 * Tested USERS command in router environment successfully with two
7205 routers, two servers and two clients.
7207 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7209 * Reorganized the USERS command and command reply in client library
7210 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
7211 When the command is given by user we register a pending command
7212 callback that will reprocess the command after the reply has been
7213 received from the server. When reprocessing the packet we then
7214 display the information. Thus, the USERS information is displayed
7215 now in the command callback instead of in the command reply
7216 callback. The processing of the command is same as previously
7217 when server has sent the command reply in the JOINing process.
7219 * Added to USERS command in silcd/command_reply.c to join the client,
7220 we didn't use to know about, to the channel after we've created
7221 a client entry for it. Also, for clienet we did know already still
7222 check whether it is on the channel or not and add it if not.
7224 * Removed silc_server_command_join_notify as the function and its
7227 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7229 * Changed the client's pending command handling to the same as the
7230 server's pending command handling. It is also now possible to
7231 execute command reply functions from other command reply
7232 function as the function callbacks for commands and command
7233 replies are one and same. The pending commands are not static
7234 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
7235 in client connection context. Thus, pending commands are server
7236 connection specific as it is convenient.
7238 Changed the function silc_client_command_pending and
7239 silc_client_command_pending_del and added new function
7240 silc_client_command_pending_check. Removed the
7241 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
7244 * Added cmd_ident, current command identifier, to the client
7245 connection context in lib/silcclient/client.h to keep track on
7246 command identifiers used in command sending. Client's command reply
7247 function handling now supports the mandatory command identifiers.
7249 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
7250 funtions in client to fully support pending command callbacks.
7252 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
7253 as one of the arguments to the application in the command reply
7256 * NOTE: The FORWARDED flag is depracated. It used to be depracated
7257 before first releasing SILC but came back. Now it is removed again
7258 and should come back nomore. The FORWARDED flag was used only
7259 by the JOINing procedure by forwarding the command packet to router.
7260 Now, the JOINing procedure has been changed to more generic (due
7261 to various router environment issues) and FORWARDED is not needed
7262 anymore for anything. The protocol specification is yet to be
7265 Now, removed silc_server_packet_forward from server and the flag
7266 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
7268 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7270 * Renamed NAMES command to USERS command. The NAMES was named that
7271 due to historical reasons. Now it is renamed. Also, rewrote
7272 parts of the USERS command. The nickname list is not sent anymore
7273 by the server. Only Client ID and mode lists are sent in the USERS
7274 command. Changed this also to the protocol specification.
7276 The client now resolves the names and stuff after it receives
7277 the USERS list from the server when joining to the channel.
7279 * WHOIS and IDENTIFY commands has been changed to support multiple
7280 Client ID's per command. One can now search for multiple users
7281 in the network by sending only one WHOIS or IDENTIFY command.
7282 Changed the code and the protocol specifications.
7284 * Removed silc_server_command_identify_parse and changed that IDENTIFY
7285 uses silc_server_command_whois_parse to parse the request. */
7287 * If normal server, do not parse the WHOIS and IDENTIFY requests
7288 before sending it to the router. Saves some time.
7290 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7292 * Fixed JOIN command on client library. Wrong number of arguments
7293 used to crash the client.
7295 * Added silc_server_channel_has_global function to check whether
7296 channel has global users or not.
7298 * Added silc_server_channel_has_local function to check whether channel
7299 has locally connected clients on the channel.
7301 * The silc_server_remove_from_one_channel now checks whether the
7302 channel has global users or not after given client was removed from
7303 the channel. It also checks whether the channel has local clients
7304 on the channel anymore. If it does not have then the channel entry
7305 is removed as it is not needed anymore.
7307 * The silc_server_notify now checks on JOIN notify whether the joining
7308 client is one of locally connected or global. If it is global then
7309 the channel has now global users on the channel and that is marked
7310 to the channel entry. Also, it now saves the global client to
7311 global list who is joining and JOINs it to the channel. This is
7312 for normal server, that is.
7314 Changed silc_server_send_notify_on_channel,
7315 silc_server_packet_relay_to_channel and
7316 silc_server_packet_send_to_channel check if we are normal server
7317 and client has router set (ie. global client) do not send the
7318 message to that client, as it is already routed to our router.
7320 * Implemented LEAVE notify type handling in silc_server_notify
7323 * Tested LEAVE command in router environment successfully. Tested
7324 with two routers, two servers and two clients.
7328 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
7330 * Implemented SIGNOFF notify type handling in silc_server_notify
7333 * silc_server_remove_id now removes the client entry from all channels
7334 it has joined and thusly sends SIGNOFF notify type.
7336 * Rewrote the NAMES list generation in server by removing two excess
7337 loops. The lists are created now inside one loop.
7339 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7341 * silc_server_remove_channel_user checks now also global list
7342 for channel and client.
7344 * silc_server_new_channel_user checks now both local and global
7345 list for channel and client. Fixed a bug in client id decoding.
7346 Used to decode wrong buffer.
7348 * silc_server_channel_message checks now both local and global
7349 list for channel entry.
7351 * Tested channel joining (hence JOIN) in router environment
7352 successfully. Tested with two routers, two servers and two
7355 * Tested channel message sending in router environment successfully.
7357 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7359 * Added silc_server_save_channel_key into server.[ch] to save the
7360 received channel key in Channel Key payload processing. It is
7361 also used in JOIN command reply handling.
7363 Equivalent function silc_client_save_channel_key added into
7364 client.[ch] into client library.
7366 * Changed JOIN command reply to send information whether the channel
7367 was created or not (is existing already) and the channel key
7368 payload. Changed protocol specs accordingly.
7370 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
7371 the request was sent by ID and not by nickname. Crashed on
7374 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7376 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
7377 now correctly save the received data.
7379 * silc_server_free_sock_user_data now notifies routers in the
7380 network about entities leaving the network.
7382 At the same time implemented functions silc_server_remove_id
7383 and silc_server_send_remove_id to receive and send REMOVE_ID
7384 packets. The packet is used to notify routers in the network
7385 about leaving entities. The ID removed will become invalid in
7388 * Added function silc_idlist_del_server into server. Removes and
7389 free's server entry from ID list.
7391 * silc_server_private_message function now checks, if we are router,
7392 that the destination ID really is valid ID, naturally.
7394 * In router when NEW_ID packet is received (for new client) the
7395 hash of the Client ID is saved in the ID Cache but the
7396 client->nickname is set to NULL, instead of putting the hash
7399 IDENTIFY command now also checks that client->nickname must be
7400 valid. If it is not if will request the data from the server who
7401 owns the client. Added new function
7402 silc_server_command_identify_check.
7404 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
7405 to set the command to already allocated Command Payload.
7407 * Tested private message sending in router environment with two
7408 routers, two servers and two clients. Fixed minor bugs and now
7411 * Fixed segfault from client's NAMES command. Used to crash if
7414 * Forwarded packets must not be routed even if it is not destined
7415 to the receiver. Changed server code comply with this.
7417 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7419 * Added `require_reverse_mapping' boolean value to ServerParams
7420 structure. If TRUE (not default) the server will require that
7421 the connecting host has fully qualified domain name.
7423 If the reverse mapping is not required and hostname could not be
7424 found the IP address is used as hostname.
7426 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7428 * Implemented version string checking to both client and server.
7429 The check is incomplete currently due to the abnormal version
7430 strings used in development version of SILC.
7432 * Changed all command functions in server to use the new
7435 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7437 * Changed char *data to unsigned char *data in ID Cache system to
7438 support binary data as ID Cache data. Changed code to support
7439 binary data in lib/silccore/idcache.c.
7441 * Renamed silc_server_packet_relay_command_reply to
7442 silc_server_command_reply as it is normal packet receiving
7443 function. Rewrote the function to accept command replys for
7444 servers and not only for clients.
7446 * Mark remote router always as registered server if we are connecting
7447 to it. Otherwise, commands sent by the router to us are ignored.
7449 * All ID List find routines now returns the ID Cache Entry pointer
7450 as well if requested.
7452 * WHOIS command works now in router environment, tested with two
7453 routers, two servers and two clients.
7455 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
7456 in router environment (as it is almost equivalent to WHOIS) but
7457 hasn't been tested thoroughly. Added new functions:
7459 silc_server_command_identify_parse
7460 silc_server_command_identify_send_reply
7461 silc_server_command_identify_from_client
7462 silc_server_command_identify_from_server
7464 * Disabled route cache adding because adding two different ID's with
7465 same IP replaces the old cache entry thus giving wrong route.
7466 The entry->router->connection is always the fastest route anyway
7467 so route cache may not be needed. Of course, new routes maybe
7468 established after receiving the ID when the entry->router->connection
7469 might not be anymore the most optimal.
7471 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7473 * Add route cache for received ID for fast routing.
7475 * Added silc_server_packet_route to route received packet on router
7476 that is not destined to us.
7478 * Renamed silc_server_get_route to silc_server_route_get.
7480 * Added id_string and id_string_len fields into SilcServer to
7481 include encoded ServerID for fast comparing without excess
7482 encoding of the ID's.
7484 * Cleaned up WHOIS command on server side. Added following static
7487 silc_server_command_whois_parse
7488 silc_server_command_whois_check
7489 silc_server_command_whois_send_reply
7490 silc_server_command_whois_from_client
7491 silc_server_command_whois_from_server
7493 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
7494 arguments in command replies. All command functions should be
7495 updated to use this macro.
7497 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7499 * Minor typo fixes on command reply handling on server.
7501 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7503 * Added silc_server_command_add_to_channel internal routine to add
7504 the client to the channel after router has created the channel and
7505 sent command reply to the server.
7507 * Added generic silc_server_send_command to send any command from
7510 * Use static buffer with ID rendering instead of duplicating data.
7512 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7514 * Fixed a channel user mode bug when joining to a channel server gave
7515 everybody channel founder rights, oops.
7517 * We mark ourselves as the router of the incoming server connection
7518 if we are router ourselves. This way we can check in some packet
7519 sending functions whether it is locally connected server. For
7520 incoming router connections we put NULL.
7522 * For router sending packets locally means now always sending the
7523 packet cell wide; to local clients and local servers. For normal
7524 server sending packet locally means sending it to only local
7527 * Fixed the JOIN command to really work in router environment. If the
7528 channel is created it is always created by the router. Router is
7529 also responsible of making the initial joining to the channel,
7530 sending JOIN notify to the sending server and distributing
7531 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
7532 does not exist server doesn't do anything else but forward the
7533 command to the router which performs everything.
7535 * Added silc_server_send_channel_key function to send the Channel Key
7538 * Added silc_server_create_channel_key to create new channel key. The
7539 channel key is now re-generated everytime someone joins or leaves
7540 a channel, as protocol dictates. Note: channel->key_len is the
7543 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7545 * Splitted server.[ch] finally. Created now packet_send.[ch] and
7546 packet_receive.[ch] to separate packet sending and receiving
7547 routines. The server.[ch] now includes everything else including
7548 actual packet processing (writing and reading data) and other
7551 Renamed silc_server_private_message_send_internal to
7552 silc_server_send_private_message. The routine is still though
7553 used only to relay private messages as server does not send
7554 private messages itself.
7556 Renamed silc_server_new_channel to silc_server_create_new_channel
7557 and added new function sicl_server_new_channel that handles the
7558 incoming New Channel packet. Added also new sending function
7559 silc_server_send_new_channel to send New Channel Payload.
7561 * Added new function silc_server_notify to process incoming notify
7562 packet to the server/router. Server may then relay the notify
7563 to clients if needed.
7565 * Added new function silc_server_new_channel_user to process incoming
7566 New Channel User packet. Router will redistribute the packet and
7567 send JOIN notify to its local clients and locally connected servers
7568 if needed. Normal server will send JOIN notify to its local client
7569 on same channel when received this packet. Added also corresponding
7570 sending function silc_server_send_new_channel_user to sent the
7573 * Added boolean route argument to send_notif_to_channel and
7574 packet_send_to_channel functions to attempt to route the packet
7575 if it is TRUE and send only locally if it is FALSE.
7577 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7579 * silc_server_replace_id now broadcasts the received replace ID
7580 packet if it is not broadcast packet already. The router must
7581 broadcast to inform other routers about changed ID.
7583 * Added backpointer to server's router into SilcServer context in
7584 silcd/server_internal.h.
7586 * Fixed silc_server_packet_broadcast to send correct broadcast
7589 * The channel key is now distributed to the local client as soon
7590 as it is received from the router (in router environment) so that
7591 no other packet may be sent for the channel until client has
7594 * silc_server_remove_channel_user now broadcasts the received
7595 Remove Channel User packet if it is not broadcast packet already.
7596 The router must broadcast to inform other routers about removed
7599 * Added users field into SilcPacketContext that is a reference count
7600 of the context. One can increase the reference count by calling
7601 silc_packet_context_dup which is now changed to just increase the
7602 reference count instead of duplicating the data. The reference
7603 count is decresed by calling silc_packet_context_free that will
7604 free the data after the reference count hits zero.
7606 For now on the packet context and everything allocated into it
7607 (including the raw packet from network) must be freed by calling
7608 the new silc_packet_context_free function. Added also new function
7609 silc_packet_context_alloc that must be used now to allocate the
7610 context. This also means that if a routine is asynchronous from
7611 silc_[client/server]_packet_parse_type the packet context must
7612 be duplicated by calling silc_packet_context_dup. Otherwise it
7613 gets free'd after silc_[client/server]_packet_parse_type returns.
7614 Also, one must remember that if packet is duplicated then its
7615 reference count must be decresed by calling the free function as
7616 many times as it was duplicated.
7618 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7619 from both client and server.
7621 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7623 * Made joining to a channel working in router environment.
7625 * Cleaned up JOIN command on server side and create function
7626 silc_server_command_join_channel internal routine to make the
7629 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7631 * Changed silc_command_pending list to SilcDList. Also, added
7632 `ident' field to SilcServerCommandPending structure to identify
7633 the reply and to call correct callback.
7635 Added silc_server_command_pending_check function to replace the
7636 corresnponding macro. The silc_command_pending list is not
7639 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7640 to set identifier to previously allocated Command Payload. It
7641 is used to set identifier for command when resending Command
7644 * Added silc_command_payload_encode_payload to encode Command
7645 Payload buffer from SilcCommandPayload structure.
7647 * Added silc_argument_payload_encode_payload to encode Argument
7648 payload buffer from SilcArgumentPayload structure.
7650 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7652 * Changed WHOIS command to support router connection on server side.
7653 The whois request is always sent to router unless the server is
7654 standalone server. After server has received the reply from the
7655 router will it send the reply to the client.
7657 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7658 broadcast received broadcast packet. The function is used only
7659 by router. The broadcast packet is always sent to the router's
7662 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7663 render given ID to printable string, for log files for example.
7665 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7667 * Made basic router to router connections working. At least they
7668 can now connect to each other but nothing really works the way
7669 they are supposed - yet.
7671 * Added new initiator token to RouterConnection configuration
7672 file in silcd/serverconfig.[ch]. It is used to tell whether we
7673 are the initiator to the remote router or whether we'll expect
7674 the other end to connect.
7676 * Moved registering of listener task to silc_server_init, hence
7677 the server starts listenning as soon as it is run, even if it
7678 does not have connections to other routers. Let's see how well
7681 * Changed default connection retry timeouts for more suitable in
7684 * Removed cipher and such arguments from silc_idlist_add_client
7685 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7686 Added new function silc_idlist_add_data to add the keys and stuff
7689 * Added SilcIDListData structure and added it to SilcClientEntry
7690 and SilcServerEntry as their first field in the structure. This
7691 way we can explicitly cast the ID entries to the SilcIDListData
7692 structure and get common data for the entries. In past, we had
7693 to first check what type of connection it is and then cast it to
7694 correct ID entry type. Now, we can directly cast the opaque
7695 pointer to the SilcIDListData (no matter what ID entry it actually
7696 is) and get the data needed.
7698 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7700 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7701 in some circumstances even if threre were timeout tasks, though not
7702 IO tasks, but tasks anyway. Now fixed.
7704 * Defined SilcServerConnection structure to hold connection specific
7705 stuff about directly connected servers and routers. The definition
7706 is currently in silcd/server_internal.h. I thought about having
7707 a bit more important role fro this struct but for now it is used
7708 only when connecting to other server (or router actually).
7710 * Added connecting retry support in server when connecting to
7711 router(s). The retry feature implement exponential backoff
7712 algorithm. Also, added SilcServerParams structure to hold default
7713 parameters for server. For now, it include these retry settings
7714 and are hard coded. After server is moded to be as Silc Server
7715 Library this structure will be more important.
7717 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7719 * Changed client librarys channel->clients table to SilcList and
7720 changed code accordingly.
7722 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7724 * Changed client's channel table to SilcList and changed code
7725 accordingly. Also changed SilcChannelClientEntry to include back-
7726 pointer to the channel so that client entry can use that structure
7727 as list as well and we have fast cross-reference to the channel.
7728 This change dramatically decreased the complexity of channel
7729 handling with client entry and vice versa (removed one extra
7730 loop when searching for channel entry from many functions).
7732 * Changed server->sim from table to SilcDList and changed code
7735 * NAMES command can now be used from user interface. It will show
7736 the user list on the channel, neatly.
7738 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7739 Code now saves realname of the user if it becomes available.
7741 * Renamed configure.in to configure.in.pre and made ./prepare
7742 script to automatically add correct version string to
7743 configure.in which it creates from configure.in.pre.
7745 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7747 * NAMES command reply now shows users mode with the nickname when
7750 * Moved silc_client_ch[u]mode[_char] functions from
7751 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7752 place sucks, they are utility functions and should be in some
7755 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7757 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7760 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7764 * Added TRQ (efficient deque and list library) into lib/trq. This is
7765 a very good list library that is currently used in the SILC. Defined
7766 SilcList API over the library because I didn't like the API very
7767 much. See lib/trq/silclist.h for the API and examples of how to
7768 use the API. Fixed various places in the code to use the new
7769 SilcList API. The SilcList is meant for lists that has a structure
7770 already defined as a list. It is not suitable to add just some
7771 context to the list (in TRQ, the context is the list actually).
7773 So, I defined SilcDList that can be used for the purpose where
7774 predefined list structure does not exit. This can be used as
7775 such list. Now some context just can be added to the SilcDList.
7776 Currently this list is not used in the SILC just yet, though there
7777 are a lot places where this can replace dynamically allocated
7778 tables and I will fix these places, later, to use SilcDList.
7779 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7780 and use TRQ internally).
7782 Also fixed some annoying warning messages that the original TRQ
7783 code generated. Also minor changes to TRQ's Makefile.in.
7785 * Added support for querying by Client ID to both WHOIS and
7786 IDENTIFY commands into server, as required by the protocol.
7788 * Removed method function pointers from SilcBuffer structure. They
7789 weren't used to anything and just increased the context size for
7790 no good reason. This change also made silc_buffer_alloc and
7791 silc_buffer_free functions inline functions.
7793 * Disabled command flooding detection support until it's fixed so
7794 that it accepts commands in but does not execute them more than once
7797 * Added silc_net_localhost(), to return local hostname, into
7798 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7799 that must be initialized before calling silc_client_init.
7801 * Added new function: silc_server_send_notify_on_channels to send
7802 notify messages to all channels client has joined. It is assured
7803 that the message is sent only once per client.
7805 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7806 lib/silcutil/silcutil.[ch] as silc_format function. The new
7807 function is generic and is used by server as well, not only by
7808 the logging routines.
7810 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7811 the provided version string was not acceptable. Added new function:
7812 silc_ske_check_version into lib/silcske/silcske.h. The function
7813 must be implemented by the application (client or server) and it
7814 does not reside in the SKE library. The function checks the version
7815 string remote end sent.
7817 * Added back pointers (to opaque context and to SilcSocketConnection)
7818 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7820 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7821 duplicate packet context structure.
7823 * Changed `notify' client operation to send same arguments as client
7824 receives from server except for ID's. ID's are mapped to correct
7825 ID entry and that is returned. Also, if channel entry is not sent
7826 by server but the notify is for channel the channel entry is sent
7827 to application (otherwise application doesn't know that it is for
7828 channel (library gets it from packet's Destination ID)).
7830 * Added silc_client_remove_from_channels into client library to
7831 remove a client from all channels it has joined to. Used when
7832 received SIGNOFF notify from server. Added also new function
7833 silc_client_replace_from_channels to replace old ID entry with
7834 new ID entry on all channels. Used when received NICK_CHANGE
7837 * Fixed ID Cache list handling in silc_idlist_get_client in
7838 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7839 to get (or query) client by ID.
7841 * Updated TODO list.
7843 * Added connection authentication status message defined by the
7844 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7845 support for these into the code in client and server side.
7847 * Added generic function silc_client_send_command to send any command
7848 with variable argument list. Application should use this function
7849 to send commands if the command functions provided by the library
7850 does not suite for the application's user interface needs.
7852 * Added new `failure' client operation. Application is notified about
7853 received failure packet if client is executing a protocol. In this
7854 case the protocol's execution has failed.
7856 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7857 is required by the protocol.
7859 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7860 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7863 * Added status flag to SilcSKE object to indicate realtime status
7864 of the SKE protocol.
7866 * Application receives now exactly same command reply arguments as
7867 the library receives from server. However, if ID is received the
7868 corresponding ID entry is returned to the application (eg. Client
7869 ID is mapped to correct SilcClientEntry entry and that is returned).
7870 Changed command_reply client operation due to this change.
7872 * Changed all ID's in commands and in command replys as ID Payloads.
7873 Change affected both client and server side codes.
7875 All ID's sent in SILC network (with execption of ID's in SILC
7876 Packet header) are sent in ID Payload to support variable length
7879 * Server now notifies nick changes and notifies all clients on
7880 the channels about the new nickname (about the new Client ID,
7883 * Implemented CMODE command to change channel modes. Supports all
7884 channel modes defined by the protocol specs except ban and invite
7885 lists. (Also, private channel key mode is supported but support for
7886 setting private channel key in client is missing, thus, this mode
7887 has no effect on client side (except that server requires that the
7888 client uses private channel key and normal channel traffic does not
7891 Also, invite mode works per se, but INVITE command does not work
7892 yet correctly, so you can set channel as invite only channel but
7893 inviting clients to the channel does not work (it is yet to be
7894 thought what's the best way to do it).
7896 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7897 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7898 Implemented CUMODE command to change user's mode on the channel.
7899 Supports all modes defined by the protocol specs.
7901 * Added NAMES command reply to return users modes on the channel.
7903 * Removed unnecessary and slow ciphers from lib/silccrypt.
7905 * Set SO_KEEPALIVE option to connection sockets by default.
7907 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7909 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7910 redefined the Notify Payload into protocol specs.
7912 * Added silc_id_payload_parse_id to get ID directly from raw
7915 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7917 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7918 accept searching by Client ID as well.
7920 * Added support for LEAVE and SIGNOFF notify types in client library.
7922 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7923 to parse ID Payload from raw data.
7925 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7927 * Added flags parameter into silc_ske_assemble_security_properties
7928 function in lib/silcske/silcske.[ch].
7930 * Changed notify client operation to fit better for notify messages
7931 sent by server. The notify payload received from server is now
7932 passed to the application (after parsing it to SilcNotifyPayload).
7933 It is application's responsibility to retrieve the arguments
7934 from the payload and show the message the way it wants. The message
7935 sent by server is implementation specific.
7937 * Changed public keys to comply with the protocol specification.
7938 Old public keys are not supported anymore and are not compatible.
7940 * Removed nickname from Channel Payload as the latest draft removed
7941 it. The client must resolve the nickname from the NAMES command
7942 reply received when it joined the channel.
7944 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7946 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7948 * Fixed some errors in protocol specification drafts.
7950 * Created lib/silccore/silcnotify.c to implement Notify Payload
7951 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7952 generic payloads described by protocol specifications. The file
7953 includes implementations for ID Payload and Argument Payload.
7955 * Changed Command Payload implementation to use the new Argument
7956 Payload. Changed command_xxxx_payload to command_payload_xxxx
7957 to comply with SILC coding conventions.
7959 * Added suppport for Argument Payload handling in Notify Payload
7960 implementation as protocol requires it. Added the new support
7961 into server and client lib as well.
7963 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7965 * Added support for multiple nicknames on same channel. [n] is
7966 added locally to the nickname if there are more than one same
7967 nicknames on the channel.
7969 * Server now sends all nicknames that matched WHOIS request.
7970 Client also shows the list received from server.
7972 * Added TOPIC command to client side. User can now set and show
7973 current topic on channel.
7975 * Added MOTD command to client and server. Also, server sends the
7976 motd when client connects to the server.
7978 * Changed version strings to comply ISO 8601.
7980 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7982 * Fixed protocol error handling in client library. It should now
7983 cope even if the SKE fails for some reason.
7985 * Made new protocol specification drafts for submitting to IETF.
7987 * Implemented TOPIC command to server in silcd/command.c.
7989 * Added two new notify types into lib/silccore/silcnotify.h:
7990 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
7991 notify nickname change and topic setting/change on a channel.
7993 * API change of command_reply operation in client library. The
7994 application gets now the status type received from server as well.
7996 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7998 * Removed the function just added to lib/silcutil/silcschedule.[ch].
8000 * Cras fixed and optimized the packet handling even further and
8001 it should work now. Minor change to the prototype of function
8002 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
8004 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8006 * Added new function into lib/silcutil/silcschedule.[ch]:
8007 silc_schedule_with_fd to select() a specified fd. The function
8008 returns after timeout expires or data arrives or goes. The
8009 function is used by packet routines to wait that all data is
8010 received from network.
8012 * Fixed data reading from network in lib/silccore/silcpacket.c.
8013 The code now assures that all data is read from the fd and then
8014 continues packet processing. This was a bug fix since the code
8015 used to drop some data in some circumstances.
8017 * Added new function into lib/silcclient/client.[ch]:
8018 silc_client_start_key_exchange to start key exchange after
8019 connection has been established to server. The code internally
8020 now uses this funtion but its main purpose was to provide it
8021 for applications that perform their own connecting. After
8022 application has created a connection it merely calls this
8023 function to start the key exchange between client and server.
8024 The library takes care of everything else after that.
8026 Updated also lib/silcclient/README to explain the usage of
8029 * Do not send to application information that connection has
8030 been established. Application gets notified it by connect
8033 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8035 * Applied cras's patch to add silc_schedule_one function. The
8036 function runs scheduler once and returns.
8038 * Fixed the scheduler after cras messed it up. The timeout
8039 handling works now as it's supposed to work.
8041 * Added into lib/silccore/ silcnotify.h to include notify
8042 message types support. Changed silc_server_send_notify*
8043 functions, in server.[ch], to support those new notify types.
8044 Added the support for the notify types into client library,
8045 as well. Added new notify client operation into ops.h in
8048 * Changed silc_server_packet_send_to_channel to send normal
8049 packets instead of just channel message packets. The function
8050 is now used to send the notify packets to channels. It is not
8051 used to send channel message packets anymore, as server never
8054 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
8055 va_arg()s as it seems to require it nowadays. I guess, if SILC
8056 is compiled with older va_arg() the new code should work anyway.
8058 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8060 * Splitted core library. Core library (lib/silccore) includes
8061 now only SILC protocol specific core (and common) components.
8062 Created new utility library (lib/silcutil) that includes more
8063 generic purpose stuff. The stuff for util library was taken
8064 from the old core library. This was minor and easy split.
8066 * Created SILC Client Library (lib/silcclient) that includes
8067 implementation of the SILC client without user interface. This
8068 was major move from silc/ directory. The code has been changed
8069 so that it is transparent towards the user interface. The
8070 silc/ directory includes now the same user interface as before
8071 and it uses the new client library. Read lib/silcclient/README.
8072 Basicly, the client library performs everything else related
8073 to SILC except user interface handling. Also, configuration
8074 files are considered to be part of user interface and library
8075 does not handle them.
8077 This change also changed a lot of structures, function naming etc.
8078 Most important change was that SilcClientWindow object was
8079 renamed to SilcClientConnection in the client library. Created
8080 also new file lib/silcclient/ops.h. Also added new files
8081 silc/local_command.[ch] and silc/client_ops.[ch].
8083 All these changes were made to make it easier for user interface
8084 designers to create what ever user interface for the SILC client
8087 It is also expected that the server will be moved to lib
8088 directory as well and SILC Server Library will be created;
8089 sometimes in the future.
8091 * Removed Local commands from lib/silccore/silccommand.h as
8092 they are application specific and new client library does not
8093 handle any of those anymore.
8095 * Several functions moved to lib/silcutil/silcutilc.[ch] from
8096 old client implementation in silc/.
8098 * Added support for callback functions in SILC_LOG_* macros.
8099 Application can now set its own callbacks that will be called
8100 instead of using the default functions that will always print
8101 the debug messages to stderr (or stdout). Also, debugging can
8102 now be disabled by setting silc_debug to FALSE and re-enabled by
8103 setting it to TRUE. Note, that logging will still work even
8104 if debugging is disabled.
8106 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
8107 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
8108 silc_log_reset_debug_callbacks.
8110 * To enable debugging in silc client one must give now -d
8111 option on command line.
8113 * Changed silc_schedule_init to automatically allocate task queues
8114 if they are not allocated before calling it.
8116 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8118 * Added GMP 3.1 into math library.
8120 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8122 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
8123 a channel in SILC network. The packet is used by servers and
8124 routers to notify other routers that user has left a channel.
8125 This little feature was missing until now. Added the feature
8126 to protocol specification as well.
8128 Added functions: silc_server_send_remove_channel_user and
8129 silc_server_remove_channel_user into server.[ch].
8131 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
8132 lib/silccore/silcpacket.h. However, they are not implemented
8135 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8137 * Fixed joining to a channel and sending channel messages
8138 between server and router. The channel message sending should
8139 now work inside a cell.
8141 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8143 * Fixed the private message sending between server and router.
8144 The private message sending should now work inside a cell.
8146 * Added silc_server_replace_id into server.[ch] to replace
8147 existing ID in the SILC network.
8149 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
8150 and silc_idlist_replace_server_id into idlist.[ch] in server.
8152 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8154 * Fixed the server to server connections. Server can again now
8155 connect to router. Router to router connections probably does
8158 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8160 * Added dynamic protocol registering support. Now protocols can
8161 registered and unregistered on the fly. Patch by cras.
8163 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8165 * Added lib/contrib directory to hold routines that some platforms
8166 don't have but are needed by SILC.
8168 * Added getopt.c, getopt1.c and getopt.h from GNU C library
8169 into lin/contrib to provide getopt() and getopt_long() for
8170 those who don't have it.
8172 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8174 * Added AWAY command to client. When away message is set and
8175 client receives a private message packet the client automatically
8176 replies to the sender with the away message.
8178 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
8179 bug seemed to be the cause of recent problems when compiling
8182 * Added version detection support to SKE protocol specification
8183 and added the new changes to the SKE implementation as well.
8184 There were other minor changes in the SKE protocol as well.
8186 Many changes in lib/silcske/silcske.[ch] and in
8187 lib/silcske/payload.[ch].
8189 * Added ^U functionality, clear input line. Patch from cras.
8191 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8193 * Mainly small bugfixes on core library. Fixed some debugging
8194 logging and buffer overflow in silclog.c.
8196 * Updated config.sub and config.guess on the distribution tree.
8198 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8200 * Added command lagging support in server. Client may execute
8201 commands now only once in two seconds.
8203 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8205 * Optimized packet reception. MAC computation and checking is now
8206 also more optimized. A lot previously duplicated code is now
8207 used as generic by both client and server.
8209 * Fixed key pair generation in clientutil.c
8211 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8213 * Added into lib/silccore/silcbufutil.[ch] new function;
8214 silc_buffer_realloc.
8216 * Moved generic packet sending/encryption functions to
8217 lib/silccore/silcpacket.[ch] from client and server. Some
8218 rewriting of the functions.
8220 * Moved all generic packet reception/decryption functions to
8221 lib/silccore/silcpacket.[ch] from client and server. The
8222 packet processing is now much cleaner in both client and server.
8223 These were major changes in both client and server.
8225 * Created many common functions in server to do packet sending.
8226 Previously code were duplicated a lot, this has been removed
8229 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8231 * Rewrote major parts of the ID cache system. Don't know
8232 whether it is better now or not but at least the API is more
8235 * Major rewrite on ID cache stuff on client because of the ID
8236 cache API changes. Added idlist.c to client.
8238 * Also major rewrite on ID cache stuff on server as well.
8239 Major rewrite of idlist.[ch]. SilcXXXList's are now named
8240 SilcXXXEntry's. We won't keep anymore idlist specific pointers
8241 in hand, instead they are all put into the ID cache system now.
8242 All server_idlist_* routines uses ID cache now instead of
8243 traversing its own lists (those lists does not exist anymore).
8244 SilcIDList though still exists. Also, SilcXXXEntry's are
8247 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8249 * Finally made the SKE implementation compliant to the protocol
8250 specification. All mp integers are now binary encoded as
8251 opposed being HEX encoded.
8253 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
8256 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
8257 functions: silc_[encode/decode]_pem. Also added function
8258 silc_encode_pem_file to PEM encode with newlines ('\n') for
8261 * SILC public keys are now encoded either PEM or binary. Same
8262 option is for private keys as well. By default private keys
8263 are binary encoded and public keys PEM encoded. Silly HEX
8264 encoding were removed.
8266 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
8267 function to create fingerprints.
8269 * Fixed a bug in SHA1; does not change the original data anymore.
8271 * Partly implemented INFO command on client and server side.
8272 Fixed CLEAR command. Changes to SERVER command; show current
8273 server(s) when giving command without arguments. Added
8274 VERSION command to client.
8276 * Added check to server that unregistered connections cannot
8277 execute commands (unless it is specificly allowed).
8279 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8281 * Fixed screen refresh.
8283 * Fixed channel joining bug from client. On some circumstances
8284 client tried to join to a channel it had already joined.
8286 * Added public key verification process into client's protocol.c.
8287 The client now verifies the public key from user and saves
8288 it into ~./silc/serverkeys/ directory.
8290 Added into: clientutil.[ch]: silc_client_verify_server_key.
8292 * Changed SKE protocol's silc_ske_initiator_finish function
8293 to accept callback function that verifies the received public
8294 key. Removed old silc_ske_verify_public_key function.
8296 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8298 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
8299 silc_pkcs_private_key[_data]_set.
8301 * Made the password and public authentication more cleaner in
8302 server's protocol.c.
8304 * Removed historic and obsolete protocol `channel_auth' from
8305 both client and server.
8307 * Removed wrong way of sending command status messages from
8308 server to client in server's command.c. The old way violated
8309 protocol specification.
8311 Changes to silccore/silccommand.[ch]: removed
8312 silc_command_encode_status_payload -> not needed anymore,
8313 changed silc_command_encode_payload_va to accept extra
8314 argument on variable argument list. The argument type must
8315 now be provided to the function. Also, added new function:
8316 silc_command_encode_reply_payload_va which is same as
8317 normal command_encode_payload_va except command status type
8318 is provided as extra argument.
8320 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8322 * Added ~./silc directory handling. The directory includes the
8323 public and private keys for the client.
8325 Added silc_client_check_silc_dir, silc_client_create_identifier
8326 and silc_client_load_keys.
8328 * Implemented SILC protocol compliant public key. Added public
8329 and private key saving to and loading from files.
8331 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
8332 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
8333 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
8334 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
8335 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
8337 Implemented: silc_pkcs_save_[public/private]_key[_data] and
8338 silc_pkcs_load_[public/private]_key.
8340 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8342 * Added silc_server_get_route (route.[ch]) to get connection
8343 data for the fastest route for given ID.
8345 * Implemented INVITE command on client and server. The command
8346 were re-defined in the SILC Protocol Specification and the
8347 implementation now complies with the specification.
8349 * Implemented PING command on client and server.
8351 * Implemented NAMES command on client and server. The server side
8352 supports currently only normal server not router server yet.
8353 Some changes to NAMES definition in SILC protocol specification.
8355 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8357 * Implemented LEAVE command on client and server.
8359 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
8360 again. This change was made to the protocol as well. Server
8361 should not violate the protocol specification anymore.
8363 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8365 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
8366 was tested. SOCKS4 was not but should work anyway.
