514 the implementation. Protocol TODO #9. Affected file is
515 lib/silccore/silcchannel.h.
517 Changed the client library to return the message length
518 to application as well in the channel_message and private_message
519 client operations. Affected files are
520 lib/silcclient/client_prvmsg, lib/silcclient/client_channel.c,
521 lib/silcclient/silcclient.h, irssi/src/silc/core/client_ops.c,
522 and lib/silcclient/client_ops_example.c.
524 * Added two new channel modes: SILC_CMODE_SILENCE_USERS
525 and SILC_CMODE_SILENCE_OPERS which can be used to moderate
526 the channel. Updated protocol specs and impelemented this
527 to client and server. Protocol TODO #6. Affected files are
528 silcd/packet_receive.c, server_util.c, lib/silcclient/command.c,
529 lib/silcclient/client_channel.c, lib/silccore/silcmode.h.
531 Added new options m and M to CMODE command in Irssi SILC
532 client to set these modes.
534 * Deprecated all administrative commands from SILC protocol
535 since they are highly implementation specific commands.
536 Updated protocol specs. Moved the old commands in
537 implementations to private range of command types. Affected
538 files are silcd/command.c, lib/silcclient/command.c and
539 lib/silcclient/command_reply.c. Protocol TODO #8.
541 * Fixed a bug in server where sending unknown command crashes
542 the server. Affected file silcd/command.c.
544 Wed Apr 3 09:57:47 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
546 * Added SILC_PROTOCOLVERSION macro to check protocol version
547 of a socket connection. The affected file is
548 lib/silcutil/silcsockconn.h.
550 * Added better error logging in rekey protocol. Affected file
553 * Do not check public key types in SKE during rekey. Affected
554 file lib/silcske/payload.c.
556 * Fixed the rekey protocol with PFS, which was totally broken.
557 Affected file silcd/protocol.c.
559 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
561 * Some client implementations quit network by doing first LEAVE
562 and then immediately SIGNOFF (like Bombyx). We now do check
563 after a short time after LEAVE notify and check whether the
564 client is still valid after LEAVE, and if not we remove it from
565 cache. Affected file is lib/silcclient/client_notify.c.
567 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
569 * Merged version 1.1.4 of zlib. Even if it not currently in use,
570 it's good not to have security holes here.
572 * Fixed a negative refcount situtuation for the config context.
573 Affected file is silcd/serverconfig.c.
575 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
577 * ROBOdoc documented lib/silcutil/silcutil.h.
579 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
581 * Optimized even more the SilcPacketContext structure. Now
582 totally saved 16 bytes of memory per context after optimization.
583 Affected files are lib/silccore/silcpacket.[ch].
585 * Made strict checks for valid SILC IDs. Affected file is
586 lib/silccore/silcid.c.
588 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
590 * Changed the object argument for silc_cipher_register,
591 silc_hash_register, silc_hmac_register and silc_pkcs_register
592 to const. Affected files are lib/silccrypt/silccipher.[ch],
593 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
595 * Changed the silc_get_username and silc_get_real_name to
596 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
598 * Fixed the Irssi SILC Client to use the silc_get_username and
599 silc_get_real_name insted of glib routines since the glib
600 routines only corrupt stack. Fixes the Irssi SILC to work in
601 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
603 * Fixed the Irssi to not use g_get_home_dir since it crashes
604 or returns garbage on cygwin and corrupts stack. Added function
605 get_home_dir to Irssi routines. Affected files are
606 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
608 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
610 * Made some structure optimizations. SFTP memory FS MemFSEntry
611 entry structure. Optimized SilcTask structure. Optimized
612 SilcPacketContext structure.
614 Affected files lib/silcsftp/sftp_fs_memory.c,
615 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
617 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
619 * And yet again reverted back the config thing since Johnny
620 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
623 * Fixed memory leaks from config object. Affected files are
624 silcd/serverconfig.[ch].
626 * Added support for adding new connections to the server in rehash.
627 After rehash they take effect.
629 Added support for changing the maximum allowed connections in
630 rehash. The number can grow but going smaller is not supported.
632 Added function silc_server_num_sockets_by_remote to the
633 silcd/server_util.[ch].
635 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
637 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
639 * Added preliminary checking during config parsing for a valid
640 public/private key and removed further checks in the code.
641 Affected files are silcd/serverconfig.[ch], server.c.
643 * Moved functions silc_server_drop() and silc_server_daemonise()
644 from server.c to silcd.c since they are stricly related to
645 the application activity.
647 * Reverted a small part of the automatic ref/unref since
648 it caused a double unref in some situations. Affected
649 files are silcd/silcd.[ch], server.c, serverconfig.c.
651 * Added some .cvsignore files in the lib directory.
653 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
655 * Fixed silc_net_gethostbyaddr to correctly resolve by
656 address. Affected file lib/silcutil/silcnet.c.
658 * Fixed the notify relaying to client. The HMAC to be used
659 with relayed packets ws wrong and caused decryption failure
660 at the client end. Affected file is silcd/packet_receive.c.
662 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
664 * Created new branch silc_protocol_1_0_branch.
666 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
668 * Changed the silc_server_config_* routines to be SilcServer
669 independent. They are now officially application specific code
670 and not part of generic server implementation. Affected files
671 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
673 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
675 * Added automatic referencing of config context in the
676 silc_server_config_alloc, and automatic unreferencing in the
677 silc_server_config_destroy. Affected files are
678 silcd/serverconfig.[ch], silcd/silcd.c.
680 * Fixed the silc_log_quick handling in the logging routines.
681 It didn't log quickly when it was TRUE. Affected file is
682 lib/silcutil/silclog.c. Also the flush delay was set even
683 if it was 0 in config file. Affected file is
684 silcd/serverconfig.c.
686 * Added support for changing key pair of the server in rehash.
687 Affected file silcd/server.c.
689 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
691 * Fixed the TOPIC_SET notify to not cras. It changed the topic
692 too early, before getting the channel entry. Affected file
693 is silcd/packet_receive.c.
695 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
697 * Added functions silc_server_config_[ref/unref], these are used
698 to prevent that the config object is destroyed.
700 No longer directly affect global variables silc_log_quick and
701 silc_log_delay, they are first cached inside the config object
702 and then applied with silc_server_config_setlogfiles().
704 silc_server_config_set_defaults() is now internal to
705 serverconfig.c, there are no reasons to show this internal stuff
708 Affected files are silcd/serverconfig.[ch].
710 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
711 fprintf's to stderr, since some code may be executed again after
712 the server went into the background. Affected files are
715 * Added rehash support. Added function silc_server_rehash() that
716 will perform all the basic tasks of the rehashing procedure.
718 * Added command line option `-x, --hexdump'. This will enable the
719 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
720 The option `--hexdump' implies `--debug'.
722 * Fixed a bad bug in the logging APIs (silcutil library) where
723 the application would crash after calling silc_log_reset_all().
725 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
727 * Fixed the KICKED notify handling in client library to
728 correctly remove the channel and all entries from the
729 channel when I was kicked. This bug crashed the client.
731 Fixed yet another but in KICKED notify handling to remove
732 the kicked client correctly from the channel.
734 Affected file is lib/silcclient/client_notify.c.
736 * Fixed a minor bug in looking up correct client entry
737 in KICKED notify in server. Affected file is
738 silcd/packet_receive.c.
740 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
741 sources correctly to distribution. Fixes --with-gmp option.
743 * Removed the manual rehashing from ID Cache, and changed it
744 to use the SILC Hash Table's auto rehash feature. Affected
745 file is lib/silccore/silcidcache.c.
747 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
749 * Fixed a bug in the silc_client_nickname_format function that
750 handles the multiple same nickname formatting. Two clients
751 with same nickname caused problems after the first one left
752 and rejoined. It didn't format the nickname correctly.
753 Affected file is lib/silcclient/idlist.c.
755 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
757 * Don't change the topic if olod topic is same as new one.
758 Affected file is silcd/packet_receive.c.
760 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
762 * Added cross-reference support to the SILC Documentation
763 generator. All types across all HTML files are now cross-
764 referenced. Affected files util/robodoc/generator.c and
765 scripts/silcdoc/silcdoc.
767 * Added file lib/silcutil/silctypes.h to include all the
768 arithmetic type definitions and some macros. Removed
769 includes/bitmove.h and moved macros to silctypes.h.
771 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
773 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
775 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
777 * Added `type' argument to silc_id_payload_parse_id function which
778 now returns the type of the ID to the sent pointer. Affected
779 file is lib/silccore/silcid.[ch].
781 * Added check for CMODE_CHANGE notify type that mode change is
782 allowed by the sender. Affected file silcd/packet_receive.c.
784 * Added check for CUMODE_CHANGE notify type that mode change is
785 allowed by the sender. Affected file silcd/packet_receive.c.
786 Added the ID type as CUMODE_CHANGE notify type as argument
787 to the `notify' client operation. Affected files are
788 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
790 * Added function silc_client_add_server to the client library.
791 Added support for resolving also channel and server info when
792 received unknown entity in notify packet. Affected files are
793 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
795 * Added function silc_command_get_status to return the command
796 status from the command reply's argument payload. Affected files
797 are lib/silccore/silccommand.[ch].
799 * Added check for KICKED notify type that the kicking is
800 allowed by the client. Affected file silcd/packet_receive.c.
802 * Created function silc_get_input which can be used to get input
803 (echo on or off) from user on command line. Affected files are
804 lib/silcutil/silcutil.[ch].
806 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
808 * Optimized silc_server_packet_relay_to_channel function.
809 Added new function silc_channel_message_payload_encrypt which
810 can be called directly if channel message payload needs to
811 be encrypted and is already encoded (no need to call _encode
812 function). Packet relaying is now done by router without any
813 extra memory allocations. Affected files are
814 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
817 * Fixed the INVITE notify handling. It took wrong arguments
818 as invite list and invite delete. Affected file is
819 silcd/packet_receive.c.
821 * Added check for TOPIC_SET notify type that the topic change is
822 allowed by the client. Affected file silcd/packet_receive.c.
824 * Added check for INVITE notify type that inviting is allowed by
825 the client. Affected file silcd/packet_receive.c.
827 * Changed the silc_server_client_on_channel to return the
828 SilcChannelClientEntry as well. Moved the function
829 silc_server_check_cmode_rights to server_util.[ch].
830 Affected files are silcd/server_util.[ch], silcd/command.c.
832 * Added function silc_server_check_umode_rights to check whether
833 changing client's user mode is allowed. Added check for
834 UMODE_CHANGE notify type that the umode change is allowed
835 by the client. Affected files are silcd/server_util.[ch],
836 silcd/packet_receive.c and silcd/command.c.
838 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
840 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
841 ID length. It ignored that ID can be IPv6 based as well.
842 Affected file lib/silccore/silcpacket.h.
844 * Fixed the silc_id_id2str and silc_id_str2id to take the
845 IPv6 address offset's into consideration. Affecte file is
846 lib/silccore/silcid.c.
848 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
850 * Fixed the internal Unix scheduler functions to check for
851 NULL context they may receive. The affected file is
852 lib/silcutil/unix/silcunixschedule.c.
854 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
856 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
857 can specify different directory with --home command line
858 parameter. Affected files irssi/src/silc/core/client_ops.c,
861 * SILC-specific commands aren't now executed if the active server
862 isn't of SILC-type, so there won't be problems with having
863 IRC and SILC protocol support in same client. Affected files
864 irssi/src/silc/core/silc-channels.c, silc-servers.c,
867 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
869 * Improved the signal support in SILC Schedule. Added new
870 function silc_schedule_signal_call which is used by application
871 to mark a signal to be called. It is now safe to perform
872 any kind of tasks in signal callbacks since it is guaranteed
873 that the application specified signal callback is called
874 after the signal is over. Affected files are
875 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
877 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
879 * Added `name' field to SilcChannelPrivateKey to represent
880 application given name for the key. Moved also the context from
881 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
882 Added the `name' argument also to the function
883 silc_client_add_channel_private_key.
885 Added function silc_client_current_channel_private_key to set the
886 current channel private key in use.
888 Added "change" command to KEY command which can be used to change
889 the current channel private key. Bound the command also to
892 Also affected files lib/silcclient/client_channel.c,
893 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
895 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
897 * Added silc_rng_get_byte_fast function in to the
898 lib/silccrypt/silcrng.[ch].
900 * Changed the interface of silc_packet_assemble and the
901 silc_packet_send_prepare. If silc_packet_assmble is now
902 called the application does not call silc_packet_send_prepare
903 because the library will call it automatically. These
904 interfaces now also return a reference to the outgoing buffer
905 which includes the assembled packet, which the application can
906 use to encrypt the packet.
908 Affected files are lib/silccore/silcpacket.[ch],
909 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
910 silcd/packet_send.c, server_backup.c and packet_receive.c.
912 * Fixed a packet sending bug on very high load, where outgoing
913 packet queue wasn't handled correctly and packets got corrupted.
914 Affected files are lib/silcutil/*/silc*sockconn.c,
915 lib/silcclient/client.c and silcd/server.c.
917 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
919 * Added macro SILC_PACKET_DATALEN which can be used during
920 packet assembling to check whether the data to be added to
921 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
922 len is truncated until it fits it.
924 Added checks for maximum length of channel message payload and
925 private message payload also.
927 Added checks for maximum packet length in server and in
930 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
931 lib/silcclient/client.c, lib/silccore/silcchannel.c and
932 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
933 lib/silcclient/client_prvmsg.c.
935 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
937 * Added silc_server_packet_queue_purge call to the
938 silc_server_disconnect_remote to assure that all data in the
939 queue before disconnecting is sent to the network. Affected
942 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
944 * Added the deleting of server's own ID cache entry to the
945 silc_server_free function. Free also everything else that
946 has been allocated in silc_server_init. The affected file
949 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
951 * Added functions silc_parse_version_string, silc_version_to_num,
952 and silc_ske_parse_version to parse SILC protocol style version
953 strings. Affected files lib/silcutil/silcutil.[ch] and
954 lib/silcske/silcske.[ch].
956 * Added new configuration params: version_protocol, version_software
957 and version_software_vendor to specify what version the remote
958 host must at least be to be able to connect to server. The vendor
959 string can be regex matched too. Added new function
960 silc_server_connection_allowed to check maximum number of allowed
961 connections, and allowed versions for incoming connections.
962 Affected files are silcd/server.c, server_util.[ch] and
965 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
967 * Added preliminary support for signals in scheduler. The
968 signals we care about are now blocked always when the scheduler
969 is locked. This way we can synchronise the use of signal with
970 scheduler. It is guaranteed that when signal occurs the scheduler
971 is not locked, and thus new tasks can be safely added to the
974 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
975 to silc_schedule_internal_init and silc_schedule_internal_uninit.
976 Added new platform specific routines
977 silc_schedule_internal_signals_[un]block and
978 silc_schedule_internal_signal_[un]register.
980 Added new functions to SILC Schedule API:
981 silc_schedule_signal_[un]register. Each signal that application
982 is going to use should be registered to the scheduler.
984 Affected files are lib/silcutil/silcschedule.[ch],
985 lib/silcutil/*/silc*schedule.c.
987 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
989 * Check for unauthenticated client and server in the
990 silc_server_new_client and silc_server_new_server functions.
991 Affected file silcd/packet_receive.c.
993 * Added function silc_string_is_ascii to check whether given
994 string is 7-bit ASCII string. Affected files are
995 lib/silcutil/silcutil.[ch].
997 * Added function silc_id_is_valid_server_id into the
998 silcd/serverid.c and added checking for valid Server ID's in
999 silc_server_new_server. The Server ID must always be based
1000 on the server's public IP address.
1002 * Added logging of DISCONNECT packet message in the server.
1003 Affected file silcd/server.c.
1005 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1007 * Changed all library interfaces that use Global RNG to also
1008 accept SilcRng as argument. Affected files are
1009 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
1010 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
1011 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
1012 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
1013 lib/silccrypt/rsa.c.
1015 * Added function silc_pkcs_generate_key to the
1016 lib/silccrypt/silcpkcs.[ch] for applications so that they
1017 don't need to do pkcs->pkcs->init calls anymore.
1019 * Remove SilcSocketConnection from the SFTP API since it really
1020 wasn't needed there. The application has the information
1021 saved in its contexts anyway and the SFTP layer doesn't need
1022 know about it. Affected files lib/silcsft/silcsftp.h and
1023 lib/silcsftp/sftp_[server/client].c.
1025 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
1026 The SilcSimContext is not SilcSim.
1028 * Fixed possible buffer overflows in silc_id_render in the
1029 lib/silcutil/silcutil.c.
1031 * On EPOC the global crypto module lists are not used at all
1032 in the crypto library. Added support for using the constant
1033 algorithm list on EPOC. Affected files are
1034 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
1037 * Fixed the handling of third parameter of KICKED notify, since
1038 it was mistakenly updated to SILC Protocol 1.0 even though it
1039 is to be included in 1.1. Since it is not in 1.0 it is not
1040 mandatory, and this fix now handles it only if it is provided,
1041 and it is not error if it is not provided. Affected file
1042 lib/silcclient/client_notify.c.
1044 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1080 hash public keys and compare public keys in hash table. Affected
1081 file lib/silcutil/silcutil.[ch].
1083 * Added support for specifying multiple public keys for Client
1084 connection section in server configuration file. This makes it
1085 possible to accept multiple public keys from same host, or to
1086 make a section that accepts any incoming host, and have the
1087 accepted public keys listed in the section.
1089 Added functions silc_sever_[find/get]_public_key, added the
1090 support for this actually to all connection sections but only
1091 the Client section is currently allowed to specify multiple
1094 Affected files are silcd/server.c, server_internal.h,
1095 command.c, protocol.c, server_util.[ch], packet_receive.c.

1114 from single host, by checking also the type of the connection.
1115 Fixed also the comparison of number of connections and number
1116 of allowed connections. Affected files are silcd/server.c,
1119 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1198 application does not need to define them. Affected file
1199 includes/silcincludes.h.
1201 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
1202 old name went against naming convention. Applications now
1203 include "silcclient.h" instead of "clientlibincludes.h".
1204 Removed includes/clientlibincludes.h, it is redundant now.
1206 * Renamed includes/version.h to silcversion.h.
1208 * Added really preliminary support for OS/2 into the util
1209 library. Only thread & mutex API is implemented, others
1210 are still to be implemented. Created the lib/silcutil/os2/
1211 directory. Created also file includes/silcos2.h.

1244 * Added `user_count' to the SilcChannelEntry which now tells the
1245 number of users on the channel. The user count is now saved
1246 in normal server of global channels as well. Affected files
1247 silcd/server.c, idlist.h, packet_receive.c and command.c.
1249 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
1250 include file utility functions.
1252 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
1253 instead of calling directly OS routines.
1255 * Fixed NICK change printing in Irssi SILC Client. Fixed
1256 KICKED notify printing in Irssi SILC Client. Affected file
1257 irssi/src/silc/core/client_ops.c.

1265 * ROBOdoc documented the lib/silcske/silcske.h, and improved
1266 the SKE interface a bit.
1268 * Fixed padding problem in PKCS#1. The padding was not actually
1269 random since the random number generator was used incorrectly.
1270 This security bug affects only when encrypting with PKCS#1, and
1271 it is not currently used at all in SILC. SILC only use signing
1272 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
1274 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1332 is now done in silc_core_init() which also fixes autoconnecting
1335 Affected files irssi/src/silc/core/silc-core.c,
1336 irssi/src/fe-text/silc.c.
1338 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1340 * Added new configuration options and blocks:
1341 keepalive_secs, reconnect_count, reconnect_interval,
1342 reconnect_interval_max, reconnect_keep_trying and
1343 require_reverser_lookup. Added ConnectionParam block, and
1344 implemented the connection parameters when connecting as
1345 initiator and when accepting connections as responder.

1357 the connection configuration object from the SilcServerConnection
1358 object instead of finding it during the connecting phase.
1359 Added the configuration object to SilcServerConnection struct.
1360 Affected files silcd/server_internal.h, server.c.
1362 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1364 * Add the client on channel after it was resolved at the
1365 channel message receiving, and it was not already on the
1366 channel. Affected file lib/silcclient/client_channel.c.
1368 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1384 authentication to be set at the same time.
1386 Added `prefer_passphrase_auth' setting in config file which
1387 can be used to set to prefer passwd auth if both passwd and
1388 public key is set. If not set, public key is preferred.
1389 This has effect only when being initiator (responder will try
1392 Added support for authentication with passphrase and public key
1393 at the same time. The passphrase is tried first always since
1394 it is faster to check.
1396 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
1398 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

1444 * Fixed the file transfer's key agreement payload to include
1445 zero port also if the hostname is NULL because it could not
1448 Call file transfer monitor callback now also if error occurs
1449 during key agreement protocol.
1451 Changed the silc_client_file_send interface to return the
1452 SilcClientFileError instead of session id. The session ID
1453 is returned into pointer provided as argument.

1470 file lib/silcutil/silclog.c.
1472 * Fixed the channel message payload decryption in the function
1473 silc_channel_message_payload_decrypt to not modify the original
1474 buffer before it is verified that the message decrypted
1475 correctly. Otherwise, next time it is called with correct
1476 channel key it won't encrypt since the payload is corrupted.
1477 Affected file lib/silccore/silcchannel.c.
1479 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1491 * Fixed a bug in hash table internal routine for traversing
1492 the table with foreach callback. The current entry may
1493 become invalid in the callback but it was referenced after
1494 the callback returned.
1496 Do not allow auto rehashing of hash table during the
1497 silc_hash_table_foreach operation, for same reasons as it is
1498 not allowed for SilcHashTableList. Affected files are
1499 lib/silcutil/silchashtable.[ch].
1501 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>

1507 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1509 * Fixed private message handling. It used some old code that
1510 caused the client to crash. Affecte file is
1511 lib/silcclient/client_prvmsg.c.
1513 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1515 * Added function silc_client_add_channel,
1516 silc_client_replace_channel_id, and removed functions
1517 silc_client_new_channel_id and silc_idlist_get_channel_by_id
1518 from client library.
1520 * Added cross reference of the joined channels to the

1522 users list to SilcHashTable. The affected files are
1523 lib/silcclient/idlist.[ch].
1525 * Fixed a bug in hash table tarversing. While the hash table
1526 is traversed with SilcHashTableList the table must not be
1527 rehashed. It is now guaranteed that auto rehashable tables
1528 are not rehashed while tarversing the list. Also defined that
1529 silc_hash_table_rehash must not be called while tarversing
1530 the table. Added function silc_hash_table_list_reset that must
1531 be called after the tarversing is over. The affected files are
1532 lib/silcutil/silchashtable.[ch].
1534 * Changed all hash table traversing to call the new
1535 silc_hash_table_list_reset in server and in client library.
1537 * Added function silc_client_on_channel to return the
1538 SilcChannelUser entry if the specified client entry is joined
1539 on the specified channel. This is exported to application as
1540 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
1542 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1545 server. The notify for mode change must be sent always and
1546 not only if !cmd->pending. Affected file silcd/command.c.
1548 * Fixed the WHOWAS command's reply sending to support the
1549 lists correctly. Affected file silcd/command.c.
1551 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1553 * When sending JOIN command to router for processing the
1554 sender's old command identifier was not saved back to the
1555 sender's command context, fixed now. The affected file is
1558 * Create the key in JOIN command of the router did not return
1559 the channel key, added check for this. Affected file is
1562 * Fixed a channel ID update bug in JOIN command reply. Do
1563 not directly upgrade the ID but call the function
1564 silc_idlist_replace_channel_id if the ID was changed.
1565 Affected file silcd/command_reply.c.
1567 * Fixed memory leaks from command calling if it would fail.
1568 Affected file silcd/command.c.
1570 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1572 * Applied patches from cras:
1574 Memory leak fixes around libaries, irssi window resize fix,
1575 new silclist.h and silcdlist.h, all extern inline changed to
1578 * Removed dotconf from lib/dotconf, not needed anymore.
1580 * Removed TRQ from lib/trq, not needed anymore.
1582 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
1583 with server connections. Later this will be configurable
1584 in config file after new config file is done. Affected file
1587 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1589 * Fixed a crash in server related to channel announcements.
1590 Affected file silcd/server.c.
1592 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1594 * Fixed memory leaks in silc_server_create_new_channel*
1595 functions. Affected file silcd/server.c.
1597 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
1598 which ID was changed. This way the router will send the
1599 user list for the channel again, and server won't be in
1600 desync in some rare circumstances. Affected file is
1601 silcd/packet_receive.c.
1603 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1605 * Check for NULL socket pointer in the function
1606 silc_server_packet_send_to_channel_real. Affected file
1607 silcd/packet_send.c.
1609 * Fixed the BAN notify handling to correctly remove ban
1610 list. Affected file silcd/packet_receive.c.
1612 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1614 * Fixed some header addition to Toolkit distribution in
1615 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
1617 * Added lib/silcclient/client_ops_example.h as an template
1618 file for application programmers to quickly start using
1619 the SilcClientOperation functions in their application.
1620 Updated the lib/silcclient/README as well to tell about this
1621 nice file made available.
1623 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1625 * Call silc_server_remove_from_channels when removing client
1626 entry when NO_SUCH_CLIENT_ID was received. Affected file
1627 is silcd/command_reply.c.
1629 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1631 * Added server & router operator statistics updating. Affected
1632 file silcd/packet_receive.c and silcd/command.c.
1634 * Fixed the SERVER_SIGNOFF notify handling on normal server
1635 not to save the history information for clients. Same was
1636 fixed earlier in remove_clients_by_server function, but not
1637 here. Affected file silcd/packet_receive.c.
1639 * Raised the default connection-retry count from 4 to 7 in
1640 server. Affected file silcd/server.h.
1642 * Cancel any possible reconnect timeouts when we start the
1643 key exchange. Affected file silcd/server.c.
1645 * Do not reconnect on connection failure when SCONNECT was
1646 given. Affected files silcd/server.[ch].
1648 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1650 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
1652 * Fixed the NICK command to always give the unformatted
1653 nickname to the one giving the NICK command. If unformatted
1654 nickname is cached already it will be formatted and the
1655 local entry will always get the unformatted nickname.
1656 Affected file lib/silcclient/idlist.c.
1658 * Fixed some double frees from client library commands.
1659 Affected file is lib/silcclient/command.c.
1661 * Fixed CUMODE command in server to assure that no one can
1662 change founder's mode than the founder itself, there was a
1663 little bug. Affected file silcd/command.c.
1665 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1667 * Removed the SilcClientCommandDestructor from the client
1668 libary, it is not needed anymore. Affected files are
1669 lib/silcclient/silcapi.h, command[_reply].[ch],
1670 client_notify, idlist.c.
1672 * Fixed GETKEY command to first resolve client, and then
1673 resolve the server only if the client was not found, instead
1674 of resolving both at the same time. Affected file is
1675 lib/silcclient/command.c.
1677 * Added silc_client_start_key_exchange_cb and lookup the
1678 remote hostname and IP address before starting the key
1679 exchange with server. The affected file is
1680 lib/silcclient/client.c.
1682 * The server's public key is now saved using the IP address
1683 of the server and not the servername for the filename.
1684 The hostname public key filename is checked as an fall back
1685 method if the IP address based filename is not found.
1687 Fixed the GETKEY command to save the fetched server key
1688 in correct filename.
1690 Print the remote server's hostname now when new key is
1691 received during connection process. Affected file is
1692 irssi/src/silc/core/client_ops.c.
1694 * Return always our own public key to the client if it asks
1695 for it with GETKEY command. Affected file silcd/command.c.
1697 * Removed the use_auto_addr variable from default config
1698 file since it was in wrong section. Affected file is
1701 * Fixed TOPIC_CHANGE notification to not route it when it
1702 was sent using silc_server_send_notify_to_channel function.
1703 Affected file silcd/command.c.
1705 * Fixed silc_server_send_notify_kicked to send the kicker's
1706 Client ID also, it was missing. Affected files are
1707 silcd/command.c, silcd/packet_send.[ch].
1709 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1711 * Do not save client history information in SERVER_SIGNOFF.
1712 Fixes the bug in normal server that it does not detect
1713 the client becoming valid after the server becomes back
1714 online. Affected file silcd/server_util.c.
1716 * Added `sock_error' field into the SilcSocketConnection
1717 context. When error occurs during socket operation (read
1718 or write) the error is saved. Added also new function
1719 silc_socket_get_error to return human readable socket error
1720 message. Affected files are lib/silcutil/silcsockconn.[ch],
1721 lib/silcutil/unix/silcunixsockconn.c, and
1722 lib/silcutil/win32/silcwin32sockconn.c.
1724 * The server now prints the socket error message in the
1725 signoff for client. Affected file silcd/server.c.
1727 * Fixed the `created' channel information sending from router
1728 to server in JOIN command. Checks now whether the channel
1729 really was created or not and set it according that.
1731 Fixed the JOIN command to use the client entry's current
1732 ID during the joining procedure instead of the one it sent
1733 in the command (it is checked though), since it can change
1734 between the packet processing and command processing, and
1735 would just case unnecessary pain in the client end. Affected
1736 file silcd/command.c.
1738 * Fixed a channel key payload sending to use correct channel
1739 ID when the server was forced to change the channel's ID by
1740 router. Router sent the key payload with the old Channel ID.
1741 Affected file silcd/packet_receive.c.
1743 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1745 * Call silc_server_save_channel_key only if the key payload
1746 was provided in the JOIN command's command reply. Affected
1747 file silcd/command_reply.c.
1749 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1751 * Fixed silc_mp_sizeinbase to return the value correctly with
1752 MPI. Affected file lib/silcmath/mp_mpi.c.
1754 * Fixed the stop_server signal to correctly stop the scheduler
1755 and gracefully stop the server when SIGTERM or SIGINT signals
1756 are received. Affected file silcd/silcd.c.
1758 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1760 * Simple handling of TERM and HUP signals. Also added some log
1761 flushing call around. Affected file is
1764 * Fixed small bugs in silclog.c. Now buffering output will take
1765 effect after 10 seconds since startup: This will ensure that
1766 no important startup messages are lost. Also output redirection
1767 will preserve original format ([Date] [Type] message).
1768 Affected file is lib/silcutil/silclog.c.
1770 * Added two options to the config file, in the logging section:
1771 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1772 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1774 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1776 * Do not print the warning about log files not being initialized
1777 more than once to avoid excess logging. Affected file is
1778 lib/silcutil/silclog.c.
1780 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1781 the SIM copying in make install in Makefile.am.pre.
1783 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1785 * Rewritten silclog APIs. Globally interesting changes follows:
1786 silc_log_set_files() changed to silc_log_set_file().
1787 silc_log_set_callbacks() changed to silc_log_set_callback().
1788 ROBOdoc documented silclog header file.
1789 SilcLogCb now returns bool to wether inihibit the default
1790 handler or not (to keep the old behaviour return always TRUE).
1791 The new APIs should also fix the problem of the
1792 silcd_error.log file that was written in the current directory.
1795 Log files streams will remain opened after silc_log_set_file()
1796 call, means less CPU usage notably on high traffic servers.
1797 File streams are now full buffered, and flushed to the disk
1798 every 5 minutes, lesses HD activity and CPU usage.
1799 Messages can be redirected, allowing admins to configure
1800 one single logfile for all server messages.
1801 the silc_log_quick global variable to activate fast-logging.
1802 Affected files lib/silcutil/silclog.[ch]
1804 * Changed some code to conform new silclog APIs. Affected
1805 files are doc/example_silcd.conf.in, silcd/server.c
1806 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1809 * Fixed a memory leak that could occur in some situations.
1810 Affected file silcd/serverconfig.c.
1812 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1814 * Added the silc_client_del_client to remove the client from
1815 all channels as well. Affected file lib/silcclient/idlist.c.
1817 * Fixed the client library to correctly remove the client
1818 from all channels when the client entry is being destroyed.
1819 Affected file lib/silcclient/client_notify.c, command.c.
1821 * Added auto-nicking support to the client library. If the
1822 applicatio now sets client->nickname it will be sent to the
1823 server after connecting by the library. This way for example
1824 SILCNICK (or IRCNICK) environment variables will have effect
1825 and always change the nickname automatically to whatever
1826 it is wanted. Affected file lib/silcclient/client.[ch].
1828 * Renamed silc_server_command_bad_chars to the
1829 silc_server_name_bad_chars and moved it to the
1830 silcd/server_util.[ch]. Added also new function
1831 silc_server_name_modify_bad to return nickname that
1832 includes bad characters as new nickname without those
1833 bad characters. This check and modify is now used in
1834 silc_server_new_client when the username is initially set
1835 as nickname, so it must be checked to be valid nickname.
1836 Affected file silcd/packet_receive.c.
1838 * The nickname length is now taken from the packet for real
1839 and not trusted to strlen() since it clearly can return
1840 wrong length for nickname including bad characters. This
1841 also applies to channel names. Affected file silcd/command.c.
1843 * Removed the lib/silcsilm/modules directory. Modules are now
1844 compiled into the lib/silcsim. Fixed the copying of the
1845 modules to follow symbolic links in Makefile.am.pre.
1847 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1849 * Fixed silc_string_regexify list creation. Fixes bugs with
1850 BAN and INVITE commands in server. The affected file is
1851 lib/silcutil/unix/silcunixutil.c.
1853 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1855 * Removed the command destructor entirely from the server's
1856 command and command reply routines. It is not needed, and
1857 its usage was buggy and caused crashes. Affected files are
1858 silcd/command[_reply].[ch].
1860 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1862 * Cancel protocol and NULL sock->protocol if timeout
1863 occurred during protocol. Affected file silcd/server.c.
1865 * Cancel protocol timeouts always before calling the final
1866 callback, to assure that after final callback is called
1867 no other state will be called for the protocol anymore.
1868 Affected file silcd/protocol.c.
1870 * Print error log if incoming connection configuration could
1871 not be found. Affected file silcd/server.c.
1873 * Fixed JOIN command to correctly save the founder mode
1874 to the client on normal SILC server, when the channel
1875 was created by the router. Affected file silcd/command.c.
1877 * Fixed LIST command (hopefully) to send correct reply
1878 packets. Affected file silcd/command.c.
1880 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1882 * The silc_packet_receive_process now returns FALSE if the
1883 read data was invalid packet, and TRUE if it was ok.
1885 The server now checks that if unauthenticated connection
1886 sends data and its processing fails the server will close
1887 the connection since it could be a malicious flooder.
1889 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1891 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1893 * Make sure the warning about error opening a log file is
1894 printed only once and not everytime it fails (produces
1895 too much useless log). Affected file lib/silcutil/silclog.c.
1897 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1899 * Made the silc_server_daemonise() function more readable.
1900 Affected file silcd/server.c.
1902 * Pid file is now optional, the user may comment it out from
1903 the config file. Removed define SILC_SERVER_PID_FILE, we
1904 don't need a default any longer. Affected file
1905 configure.in.pre, lib/Makefile.am.pre.
1907 * Make some use of the pid file. The server now dies at startup
1908 if it detects a valid pid file on his path. The server would
1909 die anyway in this circumstance, because of the bind() failure.
1910 Affected file silcd/silcd.c.
1912 * No longer compiling lib/dotconf.
1914 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1916 * Fixed JOIN command parsing not to crash. Affected file
1917 lib/silcclient/command.c.
1919 * Fied the NICK_CHANGE notify to add the new client entry
1920 even it is resolved. This removes an <[unknown]> nick
1921 thingy bug in the client. Affected file is
1922 lib/silcclient/client_notify.c.
1924 * Do not try to allocate 0 bytes (efence does not like it)
1925 in lib/silccore/silccomand.c when encoding payload.
1927 * Do not take IRCNICK as nickname in Irssi SILC client since
1928 it is not possible to set nickname before hand connecting
1929 the server (TODO has an entry about adding auto-nicking
1932 * Changed the silc_server_command_pending to check whether
1933 there already exists an pending entry with the specified
1934 command, command identifier and pending callback. This is
1935 to fix IDENTIFY and WHOIS related crashes that may register
1936 multiple pending commands with same identifier. Affected
1937 file silcd/command.c.
1939 * Fixed the server to reconnect to the router even if it
1940 was already reconnecting and EOF was received. This to
1941 fix a possibility that the server wouldn't ever try to
1942 auto-reconnect to the router. Affected file silcd/server.c.
1944 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1946 * Fixed the server's password authentication to use the
1947 length of the locally saved password, and not the one
1948 sent in the packet. Affected file silcd/protocol.c.
1950 * Fixed same password authentication problem in the
1951 Authentication Payload handling routines in
1952 lib/silccore/silcauth.c.
1954 * Yet another password authentication problem fixed with
1955 channel password handling in silcd/command.c.
1957 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1959 * If first character of string in silc_parse_userfqdn is '@'
1960 then do not parse it. Affected file is
1961 lib/silcutil/silcutil.c.
1963 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1965 * Fixed minor bug in IDENTIFY command reply sending, which
1966 caused various weird problems during JOIN when it was
1967 resolving names for users. Affected file silcd/command.c.
1969 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1971 * Fixed the IDENTIFY command reply sending to chech better valid
1972 clients. It was possible to send incomplete list of replies.
1973 Affected file silcd/command.c.
1975 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1977 * Added silc_client_command[s]_[un]register functions now to
1978 dynamically register the commands in client library. Removed
1979 the static table of commands. This allows the client library
1980 to call commands without causing the application to know about
1981 what commands library has called.
1983 Removed the INFO command reply kludge to detect when the command
1984 was called by library. Now library use its own command reply
1985 function for INFO command.
1987 Added function silc_client_command_call to call a command.
1988 Application can use it to call command, not access the structure
1991 Now all commands that are sent by the client library (not
1992 explicitly sent by application) use own command reply functions.
1994 Affected files around lib/silcclient/ and in
1995 irssi/src/silc/core/.
1997 * Fixed the WHOIS command reply sending to chech better valid
1998 clients. It was possible to send incomplete list of replies.
2000 Fixed the WHOIS and IDENTIFY to send the request to router
2001 if normal server did not do it and did not find any results.
2003 Affected file silcd/command.c.
2005 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2007 * Moved the internal data from SilcClient context into its
2008 own file, not accesible to application. Affected files
2009 lib/silcclient/client.h and lib/silcclient/client_internal.h,
2010 and other files in client library.
2012 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2014 * Added doc/examples installation target in Makefile.am.pre.
2017 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2019 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
2020 commands the found client entry will be removed from the
2021 cache, after notifying application about the error. Affected
2022 file lib/silcclient/command_reply.c.
2024 * Changed the /MSG to check for exact nickname user gave, and
2025 not let `nick' match `nick@host' if it is only one found. Now,
2026 user must type the exact nickname (like nick@host2) even if
2027 there are no more than one same nicks found. This is to avoid
2028 a possibility of sending nickname to wrong nickname since
2029 `nick' could match `nick@host'. Affected file is
2030 irssi/src/core/silc-servers.c.
2032 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2034 * Do not print "you are now server operator" or similar when
2035 giving /away command. Affected files are
2036 irssi/src/silc/core/client_ops.c, silc-servers.h.
2038 * Made the silc_server_command_pending_error_check to send
2039 the same command reply payload it received back to the
2040 original sender of the command. This way all arguments
2041 that was received by the server will be received by the
2042 client too. Affected file silcd/command.c.
2044 * Added the silc_idcache_add to return the created cache entry
2045 to a pointer. Affected file lib/silccore/silcidcache.[ch].
2047 * Add global clients to expire if they are not on any channel.
2048 This is because normal server will never know if they signoff
2049 if they are not on any channel. The cache expiry will take
2050 case of these entries. This is done by normal servers only.
2051 The affected files are silcd/command_reply.c,
2052 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
2054 * If server receives invalid ID notification for WHOIS or
2055 IDENTIFY and the ID exists in the lists, it is removed.
2056 Affected file silcd/command_reply.c.
2058 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
2059 in client then client entry that it matches is searched and
2060 the nickname is printed on the screen for user. Affected
2061 file irssi/src/silc/core/client_ops.c.
2063 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2065 * Use cache entry expire time in the LIST command reply to
2066 purge old entries from the cache after the LIST command
2067 reply has been received. This way we don't have non-existent
2068 entries in the cache for too long. Affected file is
2069 silcd/command_reply.c.
2071 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2073 * If we are normal server, and we've not resolved client info
2074 in WHOIS or IDENTIFY from router, and it is global client,
2075 we'll check whether it is on some channel. If it is not
2076 then we cannot be sure about its validity and will resolve it
2077 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
2078 file silcd/command.c.
2080 * Search channel by name (if possible) rather than by ID
2081 in IDENTIFY command's command reply. Affected file is
2082 silcd/command_reply.c.
2084 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2086 * Distribute to the channel passphrase in CMODE_CHANGE notify.
2087 Updated specs and implemented it. Affected file silcd/command.c,
2088 silcd/packet_send.c and silcd/packet_receive.c.
2090 * Implemented the <founder auth> payload handling in the JOIN
2091 command. If provided all conditions for channel joining
2092 except requirement to provide correct passphrase can be
2093 overrided by the channel founder. Updated the protocol specs.
2094 Affected file silcd/command.c.
2096 Added support for founder auth in JOIN command in client
2097 library. Fixed the parsing of the JOIN command now to support
2098 all options as they should be. The affected file is
2099 lib/silcclient/command.c.
2101 * Optimized the WHOIS and IDENTIFY commands to send the request
2102 to router only if it includes nicknames or other names. If
2103 they include only IDs then check the local cache first before
2104 routing. Affected file is silcd/command.c.
2106 * Added channels topic announcements. Affected file is
2107 silcd/packet_receive.c and silcd/server.c.
2109 * Fixed the silc_server_send_notify_topic_set to really destine
2110 the packet to channel. Affected file silcd/packet_send.c.
2112 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
2113 library. Affected file lib/silcclient/client_notify.c.
2115 * Added UMODE announcements. Affected file silcd/server.c.
2117 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>

2126 lib/silccore/silccommand.c
2127 lib/silccore/silcidcache.c
2132 * ROBOdoc documented the lib/silcske/groups.h file and a
2133 bit changed the interface for better.
2135 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2137 * Update the client entry context in the ID cache after
2138 nick change. Affected file lib/silcclient/command.c.
2139 Fixes the CUMODE command when regaining founder privileges,
2140 and a little WHOIS problem.
2142 * Fixed silc_net_gethostbyname to correctly call the
2143 inet_ntop. Affected file lib/silcutil/silcnet.c.
2145 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2147 * Added IPv6 support checking to the configure.in.pre, added
2148 also --enable-ipv6 option to override the check. Affected
2149 file configure.in.pre.
2151 * The silc_thread_create now calls the start function
2152 directly if threads support is not compiled in. Removes
2153 ugly #ifdef's from generic code. Affected files are
2154 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
2156 * Added silc_net_gethostby[name/addr]_async to asynchronously
2157 resolve. Affected files are lib/silcutil/silcnet.[ch].
2159 * Added support for rendering IPv6 based server, client and
2160 channel IDs. Affected file lib/silcutil/silcutil.c.
2162 * Added support for creating IPv6 based server IDs. Affected
2163 file is silcd/serverid.c.
2165 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2167 * Added silc_net_gethostby[addr/name] into the
2168 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
2169 routines. Added silc_net_is_ip[4/6]. Affected file is
2170 lib/silcutil/unix/silcunixnet.c. All routines that take
2171 address as argument now supports both IPv4 and IPv6 addresses.
2173 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2175 * Fixed LIST command reply sending in server. Affected file
2178 * Server now sends the kicker's client ID in the KICK notify
2179 to the kicked client. Affected file silcd/command.c.
2181 * The client library now parses the kickers client ID and
2182 UI displays it. Affected files lib/silcclient/client_notify.c
2183 and irssi/src/silc/core/silc-channels.c, module-formats.c.
2185 * Made all payload parsing function prototypes consistent.
2186 They all take now const unsigned char * and uint32 pair as
2187 the payload data instead of SilcBuffer. Changes all around
2188 the source tree. Other unsigned char* -> const unsigned char*
2189 changes around the tree as well.
2191 * Optimized SFTP client and server packet sending not to
2192 allocate new buffer for each packet but to recycle the
2193 first allocated buffer. Affected files are
2194 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
2196 * Optimized the SFTP client to use SilcList instead of
2197 SilcDList for requests, because it is faster. Affected file
2198 is lib/silcsftp/sftp_client.c.
2200 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
2201 into lib/silccore/silcid.[ch].
2203 Renamed silcpayload.[ch] into silcargument.[ch].
2205 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2207 * If client entry is deleted with active key agreement
2208 session, abort the session.
2210 The silc_client_abort_key_agreement now calls the completion
2211 callback with new SILC_KEY_AGREEMENT_ABORTED status.
2213 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
2216 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2218 * Don't use __restrict in older GCC's. Affected file is
2219 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
2221 * silc_net_localhost now attempts to reverse lookup the
2222 IP/hostname. Affected file lib/silcutil/silcnet.c.
2224 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
2225 command. It can be used to gain founder privileges at
2226 the same time when joining the channel.
2228 Defined that the SILC_NOTIFY_TYPE_KICKED send the
2229 kicker's client ID as well. Updated protocol specs.
2231 Defined that the server must send SILC_COMMAND_IDENTIFY
2232 command reply with error status to client who sent
2233 private message with invalid client ID.
2235 Updated the protocol specification.
2237 * Added silc_server_send_command_reply to send any
2238 command reply. Affected file silcd/packet_send.[ch].
2240 * Added silc_id_payload_encode_data to encode ID payload
2241 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
2243 * The server now send IDENTIFY command reply with error
2244 status if client ID in private message is invalid. Affected
2245 file silcd/packet_receive.c.
2247 * Save the server key file with server's IP address in
2248 the filename instead of hostname. The affected file is
2249 irssi/src/silc/core/client_ops.c.
2251 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2253 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
2256 * Added libtool support for compiling shared objects in
2257 lib/silcsim. Affected file configure.in.pre and
2258 lib/silcsim/Makefile.am. Original patch by cras.
2260 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2262 * Pid file configuration, and server's config file fixes
2263 patch by toma. Updated CREDITS file.
2265 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2267 * Fixed silc_client_channel_message to not try to decrypt
2268 the message twice if it resolved the destination client
2269 information. This could cause of dropping one channel
2270 message. Affected file lib/silcclient/client_channel.c.
2272 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2274 * Added silc_client_run_one into lib/silcclient/silcapi.h and
2275 lib/silcclient/client.c. This function is used when the SILC
2276 Client is run under some other scheduler, or event loop or
2277 main loop. On GUI applications, for example this may be
2278 desired to used to run the client under the GUI application's
2279 main loop. Typically the GUI application would register an
2280 idle task that calls this function multiple times in a second
2281 to quickly process the SILC specific data.
2283 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2285 * Fixed silc_server_drop() for dropping the supplementary
2286 groups as well, this could cause a security hole on some
2289 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2291 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
2294 * Write PID file after dropping privileges. Added -F option
2295 to run server on foreground. A patch by debolaz.
2296 Affected files silcd/server.c, silcd/silcd.c.
2298 * Fixed MOTD to return the MOTD file server name. Affected
2299 file silcd/command.c.
2301 * Added INFO command reply handling to the Irssi SILC Client.
2302 Affected file irssi/src/silc/core/client_ops.c.
2304 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2306 * Fixed the silc_idcache_list_* routines to really support
2307 the dynamic list. Fixes a crash. Affected file is
2308 lib/silccore/silcidcache.c.
2310 * Fixed the LIST command reply to really call LIST command's
2311 pending callbacks. Affected file silcd/command_reply.c.
2313 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2315 * Update conn->local_entry->nickname after giving NICK
2316 command. Affected file lib/silcclient/command.c.
2318 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
2320 * Added the [pid] option to the silcd configuration file
2322 Affected files: serverconfig.[ch] and silcd.c
2324 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2326 * Save fingerprint in WHOIS command reply in server.
2327 Affected file silcd/command_reply.c.
2329 * Fixed NICK commands pending callback registration.
2330 Affected file lib/silcclient/command.c.
2332 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2334 * Use ++server->cmd_ident when sending commands in server,
2335 instead of random number. Affected file silcd/command.c.
2337 * Fixed GETKEY command reply to call actually GETKEY pending
2338 command callbacks. Affected file silcd/command_reply.c.
2340 * A bit stricter check for nicknames. Check for same nickname
2341 in NICK command also. Affected file silcd/command.c.
2343 * Do not call INFO command everytime client ID changes, only
2344 during first connecting. Affected file lib/silcclient/client.c.
2346 * Set the new nickname only after successful command reply for
2347 NICK command is returned by server. Affected file
2348 lib/silcclient/command.c.
2350 * Remove nicknames from nicklist during server_signoff notify.
2351 Should fix /NAMES bit more. The affected file is
2352 irssi/src/silc/core/silc-channels.c.
2354 * Added `fingerprint' field to the SilcIDListData in the
2355 silcd/idlist.h to hold the fingerprint of the client's
2358 Send the fingerprint of the client's public key in WHOIS
2361 Affected files silcd/command.c, and silcd/idlist.[ch].
2363 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
2364 create fingerprint from given data.
2366 * Show the fingerprint of the client's public key in WHOIS.
2367 Affected files irssi/src/module-formats.[ch] and
2368 irssi/src/silc/core/client_ops.c.
2370 * Format the multiple same nicknames also during JOIN and
2371 NICK_CHANGE notifys. Affected file is
2372 lib/silcclient/client_notify.c.
2374 * Do not print error on screen for invalid private message
2375 payload since it can come if someone is sending private
2376 messages with wrong key. Affected file
2377 lib/silccore/silcprivate.c.
2379 * Fixed multiple concurrent /PING crash. Affected file
2380 lib/silcclient/command.c.
2382 * Changed the wrong ID encoding. All IP addresses must be
2383 in MSB first order in encoded format. They were encoded
2384 wrong and was in LSB format. Affected files are
2385 silcd/serverid.c, lib/silcutil/silcutil.c.
2387 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
2389 * Call the `connect' client operation through the scheduler
2390 in case of error. Affected file lib/silcclient/client.c.
2392 * Call the `failure' client operation even if the error
2393 occurred locally during a protocol. Affected file is
2394 lib/silcclient/protocol.c.
2396 * Added support of sending LIST command to router from normal
2397 server. This way normal server can get list of all channels
2398 in the network too. Fixed the channel list sending in the
2399 server too. Affected files are silcd/command.c, and
2400 silcd/command_reply.[ch].
2402 * Added silc_server_update_channels_by_server and
2403 silc_server_remove_channels_by_server. They are used during
2404 disconnection of primary router and in backup router protocol.
2405 Affected file silcd/server_util.[ch], silcd/server.c and
2406 silcd/server_backup.c.
2408 * Fixed channel adding to global list in IDENTIFY command
2409 reply in server. Affected file silcd/command_reply.c.
2411 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2413 * If the incoming packet type is REKEY or REKEY_DONE process
2414 that packet always synchronously. Fixes yet another MAC
2415 failed error on slow (dialup) connections. Affected file
2416 lib/silcclient/client.c and silcd/server.c.
2418 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2420 * Call check_version SKE callback for initiator too. Affected
2421 file lib/silcske/silcske.c.
2423 * Implemented fix for security hole found in the SKE that was
2424 fixed in the specification few days back; the initiator's
2425 public key is now added to the HASH value computation.
2426 Added backwards support for the old way of doing it too, for
2427 old clients and old servers. Affected file is
2428 lib/silcske/silcske.c.
2430 * Enabled mutual authentication by default in SKE. If initiator
2431 is not providing mutual authentication the responder will
2432 force it. This will provide the proof of posession of the
2433 private key for responder. The affected files are
2434 lib/silcclient/protocol.c and silcd/protocol.c.
2436 * Do not cache anymore the server's public key during SKE.
2437 We do mutual authentication so the proof of posession of
2438 private key is done, and if the server is authenticated in
2439 conn auth protocol with public key we must have the public
2440 key already. Affected file silcd/protocol.c.
2442 * Added new global debug variable: silc_debug_hexdump. If
2443 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
2444 file lib/silcutil/silclog.[ch].
2446 * Fixed compilation warning due to char * -> const char *.
2447 Affected files lib/silcutil/silcnet.h, and
2448 lib/silccore/silcauth.[ch].
2450 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2452 * Fixed CMODE command when new channel key was created. If
2453 the creation failed the old key was removed. Next time giving
2454 same command would crash the server since the old key was
2455 freed already. Affected file silcd/command.c.
2457 * Fixed the silc_server_announce_get_channels to not crash
2458 on reconnect. Affected file silcd/server.c.
2460 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2462 * Added silc_log_set_debug_string function to set a regex
2463 string to match for debug output. Only the function names,
2464 or filenames matching the given debug string is actually
2465 printed. This way it is possible to filter out those debug
2466 strings that user is not interested in.
2468 Fixed a bug in silc_string_regexify.
2470 Affected files lib/silcutil/silclog.[ch], and
2471 lib/silcutil/unix/silcunixutil.c.
2473 * Changed the -d options in both server and Irssi SILC client
2474 to take the debug string as argument. Affected files
2475 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
2477 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2479 * Added silc_hash_babbleprint to create a Bubble Babble
2480 Encoded fingerprint. The encoding is developed by Antti
2481 Huima (draft-huima-babble-01.txt), and it creates human
2482 readable strings out of binary data. Affected file
2483 lib/silccrypt/silchash.[ch].
2485 * Print the babble print now in addition of fingerprint as well
2486 in Irssi SILC client. Affected files are
2487 irssi/src/fe-common/silc/module-formats.[ch],
2488 irssi/src/fe-common/silc/core/client_ops.c.
2490 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2492 * Fixed a security problem found in SKE. The initiator's
2493 public key too is now added to the HASH hash value creation
2494 which is signed by the responder to create the SIGN value.
2495 This will prevent anyone in the middle to lie to the responder
2496 about the initiator's public key. If this is done now, the
2497 man in the middle will get caught. Updated the protocol
2500 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2502 * Better installation directory handling. Configure module
2503 paths and other paths automatically to example_silc* files
2504 in doc/. A patch by toma.
2506 * Fixed compiler warning from MPI library, and from SILC RNG.
2509 * Added SILC_SERVER_PID_FILE to define the pid file for server.
2510 It can be configured with ./configure. A patch by toma.
2512 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2514 * Find correct make to use in prepare-clean. A patch by
2515 toma. Affected file prepare-clean.
2517 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
2519 * Added irssi variables use_auto_addr, auto_bind_ip,
2520 auto_bind_port and auto_public_ip.
2522 * Changed the interface for silc_client_send_key_agreement
2523 in lib/silcclient/silcapi.h
2527 irssi/src/silc/core/silc-core.c
2529 lib/silcclient/silcapi.h
2530 irssi/src/silc/core/silc-channels.c
2531 lib/silcclient/client_keyagr.c
2534 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2536 * Added silc_pkcs_public_key_compare to compare two
2537 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
2539 * Check that the client who set the founder mode on the
2540 channel is the same client that is giving the founder
2541 mode to itself. It is done by comparing the saved public
2542 key (it is saved even in the authentication is passphrase).
2543 Affected file silcd/command.c.
2545 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2547 * Do not process packet for disconnected socket connection.
2548 Affected file lib/silccore/silcpacket.c.
2550 * Process the DISCONNECT packet through scheduler in the
2551 client library. Affected file lib/silcclient/client.c.
2553 * Fixed the silc_client_packet_parse to not to increase
2554 the packet sequence number if the conn->sock and the
2555 current socket connection is not same. This can happen
2556 for example during key agreement when the conn includes
2557 multiple socket connections (listeners). Affected file
2558 lib/silcclient/client.c.
2560 * The sender of the file transfer request now provides also
2561 the pointer (listener) for the key exchange protocol. If
2562 the listener cannot be created then it sends empty key
2563 agreement and lets the receiver provide the listener.
2565 Added `local_ip' and `local_port' arguments to the
2566 silc_client_file_send. If they are provided they are used,
2567 if not then it will attempt to find local IP address, if
2568 not found or bind fails then the remote client will provide
2571 Affected files are lib/silcclient/client_ftp.c and
2572 lib/silcclient/silcapi.h.
2574 * Extended the FILE SEND command to support defining the
2575 local IP and port for key exchange listener. They are
2576 optional. Affected file irssi/src/silc/core/silc-servers.c.
2578 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2580 * Defined to WHOIS command reply the sending of fingerprint
2581 of the client's public key (if the proof of posession of the
2582 corresponding private key is verified by the server).
2583 Updated to the protocol specification.
2585 * Added support of receiving the client's public key's
2586 fingerprint in command reply in client library. Affected
2587 file is lib/silcclient/command_reply.c, and
2588 lib/silcclient/idlist.[ch].
2590 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2592 * Do not send over 128 chars long nickname to the server
2593 in NICK command. Affected file lib/silcclient/command.c.
2595 * Do not send over 256 chars long channel names to the server
2596 in JOIN command. Affected file lib/silcclient/command.c.
2598 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2600 * Assure that silc_server_close_connection cannot be called
2601 twice for same socket context. Affected file is
2604 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2606 * Send error message to application if opening file for
2607 writing during file transfer fails. Affected file is
2608 lib/silcclient/client_ftp.c.
2610 Remove all file transfer sessions for a client that we're
2611 removing from ID cache.
2613 Affected file is lib/silcclient/client_ftp.c.
2615 * Fixed silc_net_addr2bin to return correct address. Affected
2616 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.

2643 client library. Affected file lib/silcclient/client_prvmsg.c.
2645 * Do not actually remove the client directly from ID cache
2646 during SERVER_SIGNOFF, but invalidate it. This way we
2647 preserve the WHOWAS info for the client. Affected file
2648 silcd/server_util.c.
2650 * Fixed SERVER_SIGNOFF notify handling in the server. The
2651 server is now able to process incoming SERVER_SIGNOFF notify
2652 for a server that it doesn't even know about. It will remove
2653 the clients provided in the notify. Affected file
2654 silcd/packet_receive.c.
2656 * Check for partial packet in data queue after every packet that
2657 was found from the queue. Return and wait for more data if
2658 there is partial data in queue. Affected file is
2659 lib/silccore/silcpacket.c.
2661 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>

2669 * Check that newsize in silc_buffer_realloc is larger than
2670 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
2672 * Added better monitor of file transfers. It now monitors
2673 key agreement protocol during the file transfer too. Added
2674 error reporting too. Affected files
2675 irssi/src/silc/core/silc-servers.c,
2676 irssi/src/fe-common/silc/module-formats.[ch].
2678 * Wrote a help file for FILE command.
2680 * Added silc_rng_global_get_byte_fast to get not-so-secure
2681 random data as fast as possible. Random data is read from
2682 /dev/urandom if available and from the SILC RNG if not
2683 available. It is used in padding generation. Affected file
2684 lib/silccrypt/silcrng.[ch].
2686 * All packets in client library are now processed synchronously.
2687 Optimized packet processing a lot. Affected file
2688 lib/silcclient/client.c.
2690 * All server connection packets are processing synchronously
2691 now in server, to optimize packet processing. Affected file
2694 * Include files are installed now only in Toolkit distribution
2695 if make install is given. Affected files: all Makefile.am's.
2697 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2699 * Assure that silc_client_notify_by_server_resolve does not
2700 resolve the client information multiple times. If it cannot
2701 be found by the first it cannot be found at all. Affected
2702 file lib/silcclient/client_notify.c.
2704 * Fixed WHOWAS command reply calling. Affected file
2705 lib/silcclient/command_reply.c.
2707 * Removed all references to silc_idlist_get_client from the
2708 Irssi SILC client since that call is internal call used by
2709 the library. The Irssi SILC client will use now client
2710 retrieval functions found in silcapi.h.
2712 * Fixed a bug in resolving nickname info before sending
2713 private message. It used freed memory. Affected file
2714 irssi/src/silc/core/silc-servers.c.
2716 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2718 * Assure my_channels statistics cannot go negative in server.
2719 Affected files silcd/server.c, silcd/server_util.c.
2721 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

2735 * Added silc_net_localip to return local host's IP address.
2736 Affected file lib/silcutil/silcnet.[ch].
2738 * If key exchange or rekey protocol is active for a connection
2739 parse all packets syncronously since there might be packets
2740 in packet queue that we are not able to process without first
2741 processing packets before them. Affected file silcd/server,
2742 lib/silcclient/client.c.
2744 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2745 whether library should continue processing the packet.
2746 Affected file lib/silccore/silcpacket.h.

2777 lib/silcutil/silcutil.[ch].
2779 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2781 * Resolve the client info when received private message or
2782 channel message for a client which nickname we don't know.
2783 Affected files lib/silcclient/client_prvmsg.c and
2784 lib/silcclient/client_channel.c.

2792 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
2793 is incomplete and is being resolved, it won't be resolved
2796 Make sure also that USERS command reply does not resolve
2797 twice information. Affected file is
2798 lib/silcclient/command_reply.c.
2800 Make sure that silc_client_get_clients_by_list does not
2801 resolve twice same information.
2803 * Check for valid client->id in the silc_server_free_client_data.
2804 Affected file silcd/server.c.
2806 * Fixed /GETKEY nick@server not to crash if the server entry
2807 is not found. Affected file lib/silcclient/command.c.
2809 * Fixed the silc_server_check_cmode_rights to check the
2810 requested modes correctly. Affected file silcd/command.c.

2815 Affected file silcd/command.c.
2817 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2819 * Call the silc_server_udpate_servers_by_server in the
2820 primary router that comes back online in the backup resuming
2821 protocol. Otherwise it routes packets wrong. Affected file
2822 silcd/server_util.[ch], silcd/server_backup.c.
2824 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2826 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2827 lib/silcutil/silcbuffmt.[ch].
2829 * Redefined the SILC packet header to include the padding
2830 length. Affected file lib/silccore/silcpacket.[ch].
2832 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2833 length for maximum padding up to 128 bytes). Affected
2834 file lib/silccore/silcpacket.h.
2836 * Removed all backwards support for old 0.5.x MAC thingies.
2837 The SILC packet header change makes it impossible to be
2838 backwards compatible.
2840 * Send the ENDING packet with timeout in the backup resuming
2841 protocol. This is to assure that all routers has connected
2842 to the primary router. Affected file silcd/server_backup.c.
2844 * Changed the RNG to take the first IV from random data. It
2845 used to take it from zero actually. Changed the RNG also
2846 to use /dev/urandom during session. /dev/random is used
2847 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2849 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2851 * Changed the SILC packet header to have the first two bytes
2852 (the packet length) encrypted. Affected files aroung the
2853 code tree, lib/silccore/silcpacket.[ch]. Removed the
2854 SilcPacketCheckDecrypt callback. It is not needed anymore
2855 since the silc_packet_receive_process will determine now
2856 whether the packet is normal or special.
2858 * Implemented the unidirectional MAC keys. Affected files
2859 lib/silcske/silcske.c, silcd/protocol.c and
2860 lib/silcclient/protocol.c.
2862 * Implemented the packet sequence number to the MAC computation.
2863 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
2864 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
2865 lib/silcclient/protocol.c.
2867 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2869 * Allow backup router to announce servers. All servers
2870 announced by backup router are added to the global list
2871 automatically. Update hte server's socket to our primary
2872 router also when backup router announces a server.
2873 Affected file silcd/packet_receive.c.
2875 * Do not update the client->router in the function
2876 silc_server_udpate_clients_by_server if the client is on
2877 global list. We might fail to find any specific server
2878 for locally connected clients and local cell clients. They
2879 should still use the `from' and not `to' as client->router.
2880 This fixes backup router resuming protocol. Affected file
2881 silcd/server_util.c.
2883 * Decrease channel statistics count only if the channel
2884 deletion worked. Affected files are silcd/server.c and
2885 silcd/server_util.c.
2887 * Added silc_server_update_servers_by_server to update origin
2888 of all server entries. Used during backup router protocol.
2889 Affected files silcd/server_util.[ch], silcd/server.c. and
2890 silcd/backup_router.c.
2892 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
2893 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
2894 silc_hmac_get_hash and silc_hmac_get_name. Affected file
2895 lib/silccrypt/silchmac.c.
2897 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2899 * Assure that router cannot reroute the same channel message
2900 to the sender. Affected file silcd/packet_receive.c.
2902 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2904 * Made better checks that the channel message is not sent
2905 to the router it came from. Affected file is
2906 silcd/packet_send.c. Fixed memory leak too.
2908 * Announce informations for incoming router connection, but
2909 only after checking if it is replaced by backup router.
2910 Affected file silcd/packet_receive.c.
2912 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2914 * Fixed the backup resuming protocol to work in multiple
2915 router environment. Affected file silcd/server_backup.c.
2917 * Route packet only to one router in the function
2918 silc_server_packet_send_to_channel. Affected file is
2919 silcd/packet_send.c.
2921 * Fixed silc_server_send_notify_dest to set the broadcast
2922 flag. Fixed the silc_server_send_notify_topic to actually
2923 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2924 Affected file silcd/packet_send.c.
2926 * Changed the SFTP Filesystem interface. Changed the
2927 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2928 the filesystem operation function. The SilcSFTPFilesystem
2929 is now a context that is allocated by all filesystem allocation
2930 functions and it already includes the operations structure
2931 and filesystem specific context. It is given as argument
2932 now to the silc_sftp_server_start. This made the interface
2933 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2934 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2936 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2938 * Changed the backup router adding and getting interfaces
2939 in the server. The router that will be replaced by the
2940 specified backup router is now sent as argument. Affected
2941 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2944 * Added silc_net_addr2bin_ne to return the binary form of
2945 the IP address in network byte order. Affected files
2946 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
2948 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2950 * Check for existing server ID in silc_server_new_server
2951 and in silc_server_connect_to_router_final and remove the
2952 old entry if it exists. Affected file silcd/packet_receive.c,
2955 * Send the channel message always to only one router, either
2956 in upstream or downstream. Affected file is
2957 silcd/packet_send.c.
2959 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2961 * Wrote the definition of the backup resuming protocol to the
2962 protocol specification.
2964 * Removed one redundant channel key generation from normal
2965 server during joining procedure. Removed one redundant
2966 channel key sending from server to router during joining
2967 procedure. Affected file silcd/command.c.
2969 * Made minor bugfixes to the backup router resuming protocol.
2970 Affected file silcd/server_backup.c, server.c.
2972 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2974 * Added --disable-asm configuration option. Affected files
2975 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
2978 * Implemented the backup resuming protocol that is used to
2979 resume the primary router position in the cell after the
2980 primary router comes back online. Affected files
2981 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
2982 and silcd/server_util.[ch].
2984 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2986 * Sleep two (2) seconds after sending QUIT command to server.
2987 Affected file lib/silcclient/command.c.
2989 * Assure that if outgoing data buffer is pending do not force
2990 send any data. Affected file silcd/packet_send.c.
2992 * Assure that if outgoing data buffer is pending do not force
2993 send any data. Affected file lib/silcclient/client.c.
2995 * Implemented the backup router support when the primary router
2996 goes down. The servers and routers can now use the backup
2997 router as new primary router without loosing connectivity.
2999 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3001 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
3002 in the server to indicate disabled entry. All data read
3003 from the connection will be ignored and no data is sent
3004 for entry that is disabled. Affected files are
3005 silcd/idlist.h, silcd/server.c.
3007 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3009 * Created SFTP client and server test programs in the
3010 lib/silcsftp/tests directory.
3012 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3014 * Implemented memory filesystem (virtual filesystem) for
3015 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
3018 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3020 * Implemented the SFTP (SSH File Transfer Protocol) to the
3021 lib/silcsftp. It includes SFTP client and SFTP server
3024 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3026 * Moved lib/silccore/silcprotocol.[ch] to the
3027 lib/silcutil library.
3029 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
3030 take variable argument list pointer as argument. Affected
3031 file lib/silcutil/silcbuffmt.[ch].
3033 * Added silc_buffer_set function that is used to set data
3034 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
3035 Affected file lib/silcutil/silcbuffer.h.
3037 * Changed various routines in the core library to use the new
3038 silc_buffer_set instead of allocating new buffer only for
3041 * Added 64-bit value formatting and unformatting support to the
3042 silc_buffer_[un]format routines. Affected file is
3043 lib/silcutil/silcbuffmt.[ch].
3045 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
3046 to includes/bitmove.h.
3048 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3050 * Fixed channel user mode saving in client library. Affected
3051 file lib/silcclient/command[_reply].c.
3053 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3055 * Defined the file transfer to the SILC Protocol. Added
3056 new packet type SILC_PACKET_FTP and defined File Transfer
3057 Payload. The mandatory file transfer protocol is SFTP
3058 (SSH File Transfer Protocol). Affected file in addition
3059 of the internet draft is lib/silccore/silcpacket.h.
3061 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
3062 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
3063 is used as part of backup router protocol when the primary
3064 router of the cell is back online and wishes to resume
3065 the position as primary router.
3067 * Redefined the MAC generation keys in the protocol. The
3068 same key is not used anymore in both direction. Both
3069 direction will now use different keys for sending and
3070 receiving. This fixes a potential security flaw. This
3071 change causes incompatibilities in the protocol.
3073 * Redefined also the MAC computation from the packet.
3074 An packet sequence number is now added to the MAC
3075 computation. This prevents possible replay attacks against
3076 the protocol. This change too causes incompatibilities
3079 Added `sequence' field to the SilcPacketContext to hold
3080 the current sequence number for the packet.
3082 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3084 * Added `created' field to the SilcIDListData in the file
3085 silcd/idlist.h to indicate the time when the entry was
3088 * Added `created' field to the SilcChannelEntry too. Affected
3089 file silcd/idlist.h.
3091 * Added `creation_time' aguments to all the announcement functions
3092 in the server. If it is provided then only the entries that
3093 was created after the provided time frame are actually
3094 announced. Affected file silcd/server.[ch].
3096 * The protocol says that the Channel ID's IP address must be
3097 based on the router's IP address. Added check for this in
3098 the silc_server_new_channel when processing incoming New Channel
3099 Payload. Affected file silcd/packet_receive.c.
3101 * Print out the correct version with --version in SILC client.
3102 Affected file irssi/src/silc/core/silc-core.c.
3104 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3106 * Fixed WHOWAS command to check for completnes of the client
3107 entry always, not just when the command is coming from client.
3108 Affected file silcd/command.c.
3110 * Added new function silc_server_packet_queue_purge to purge the
3111 outgoing data queue to the network. After the function returns
3112 it is guaranteed that the outgoing packet queue is empty.
3113 Affected file silcd/packet_send.[ch].
3115 * Purge the outgoing packet queue in the rekey protocol's final
3116 callback to assure that all rekey packets go to the network
3117 before quitting the protocol. Affected file silcd/server.c.
3119 * Added silc_client_packet_queue_parse as similar function as
3120 in server to the client library. The affected file is
3121 lib/silcclient/client.c.
3123 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3125 * Splitted silcd/server.c and created silcd/server_util.[ch]
3126 for utility functions.
3128 * Added new socket flag SILC_SF_DISABLED to indicate that the
3129 connection is open but nothing can be sent to or received from
3130 the connection. Affected file lib/silcutil/silsockconn.[ch].
3131 The checking for disabled socket is checked in the low level
3132 silc_socket_write and silc_socket_read functions.
3134 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3136 * Allow only nicknames and channel names that fits into the
3137 7-bit unsigned char ASCII set. Affected file silcd/command.c.
3139 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3141 * When processing JOIN command reply in server check that if
3142 the channel exists in our global list we'll move it the local
3143 list. Affected file silcd/command_reply.c.
3145 * Fixed the check whether client is joined on the channel already
3146 in JOIN command. Affected file lib/silcclient/command.c.
3148 * Fixed the JOIN command reply to check whether the channel
3149 already exists. Affected file lib/silcclient/command_reply.c.
3151 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3153 * Added silc_ske_status_string to map the SKE error numbers
3154 to readable strings. The affected files are
3155 lib/silcske/silcske[_status].[ch].
3157 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3159 * Do not show the private channels on the WHOIS channel list
3160 as it is not allowed by the protocol. The affected file is
3163 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3165 * Assure that the packet length digged from the actual packet
3166 is something sensible in the silc_packet_decrypt_rest_special
3167 in lib/silccrypt/silcpacket.c.
3169 * Free and NULL the allocated pointer in silc_hmac_alloc if
3170 the HMAC allocation fails. The affected file is
3171 lib/silccrypt/silchmac.c.
3173 * Print the selected security properties to the log files in
3174 the server. Affected file silcd/protocol.c.
3176 * Add SKE's reference counter even if calling the completion
3177 callback manually. Otherwise it goes negative, although it
3178 does not cause any problems. The affected file is
3179 lib/silcske/silcske.c.
3181 * Remove the client entry with short timeout after giving the
3182 KILL command. Affected file lib/silcclient/command.c.
3184 * Fixed to send error reply in WHOIS and IDENTIFY commands in
3185 case all found clients are already disconnected (WHOWAS would
3186 found them) in the server. Affected file silcd/command.c.
3188 * Update the last_receive (time of last data received) to be
3189 updated only when received private or channel message so that
3190 the idle time showed in WHOIS makes more sense.
3192 * Added boolean field `valid' in to the SilcClientEntry in the
3193 client library to indicate whether the entry is valid or not.
3194 This fixes the nickname change bug on channel when changing
3195 the nickname to be same than the old (like nick to Nick) the
3196 nickname formatter doesn't set the new nick anymore to Nick@host.
3197 Affected file lib/silcclient/idlist.[ch].
3199 * Now actually fixed the nickname changing on disconnection.
3200 Added new function silc_change_nick to the Irssi SILC Client.
3201 Affected file irssi/src/silc/core/client_ops.c,
3202 irssi/src/silc/core/silc-nicklist.[ch].
3204 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3206 * Check that the public key exists in the GETKEY command before
3207 trying to encode it. Affected file silcd/command.c.
3209 * Print some notifications on received public keys with GETKEY
3210 command in the Irssi SILC Client. Affected files are
3211 irssi/src/fe-common/silc/module-formats.[ch],
3212 irssi/src/silc/core/client_ops.c.
3214 * Use IDENTIFY command to resolve the server information in the
3215 GETKEY command instead of INFO command. Affected file
3216 lib/silcclient/command.c.
3218 * All command reply functions in the client library now calls
3219 the pending command reply callbacks even if an error has
3220 occurred. The server has done this a long time and now it was
3221 time to move the client library to this as well. Now all
3222 errors can be delivered back to the pending command reply
3223 callbacks if necessary. Affected files are
3224 lib/silcclient/command[_reply].[ch].
3226 * Change the nickname on disconnection back to the username
3227 because in reconnect the server will enforce it to it anyway.
3228 Affected file irssi/src/silc/core/silc-servers.c.
3230 * Fixed a config file parsing bug in the Irssi SILC client.
3231 Affected file irssi/src/silc/core/clientconfig.c.
3233 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3235 * When printing the channel mode on JOIN, verify that the
3236 channel key and channel's HMAC are valid. Affected file
3237 irssi/src/silc/core/client_ops.c.
3239 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3241 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
3242 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
3243 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
3245 * Removed channel key rekey task deleting from the function
3246 silc_server_save_channel_key. Affected file silcd/server.c.
3247 Added explicit timeout task context instead that is used to
3248 delete the task if we are registering a new task before the
3249 new task has elapsed.
3251 * When channel key rekey occurs the client library now saves
3252 the old channel key for a short period of time (10 seconds) and
3253 is able to use it in case some is still sending channel
3254 messages encrypted with the old key after the rekey. Affected
3255 file lib/silcclient/[idlist.h|client_channel.c].
3257 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3259 * Added check to the silc_server_new_id_real to not accept
3260 new ID if it is the sender's own ID. Affected file is
3261 silcd/packet_receive.c.
3263 * Assure that we do not announce ourself or the one we've
3264 sending our announcements when we're router and are announcing
3265 servers to our primary router. Affected file silcd/server.c.
3267 * Fixed silc_server_command_identify_check_client to assemble
3268 correct WHOIS packet. It send corrupted WHOIS packet and
3269 caused problem with router to router connections. Affected
3270 file silcd/command.c.
3272 Fixed also silc_server_command_whois_check the same way
3273 as for the IDENTIFY command.
3275 * Added new SilcIDListStatus to the server in the SilcIDListData
3276 structure. The status now includes the current status of
3277 the entry (like registered, resolved etc.). Affected file
3278 silcd/idlist.[ch]. Defined a bunch of different status types
3279 as well. This replaced the old boolean registered field as well.
3281 Added resolve_cmd_ident field to the SilcClientEntry structure
3282 too so that if the entry is for example being resolved so
3283 another command may attach to the same pending command reply
3284 without requiring to resolve the same entry again. This concept
3285 should optimize the WHOIS and the IDENTIFY resolving under
3286 heavy load by taking away unnecessary resolving for entries
3287 that are being resolved already.
3289 Added support for adding multiple pending commands for one
3290 command idenfier. Affected file silcd/command[_reply].[ch].
3292 * Fixed WHOIS and IDENTIFY save to remove the cache entry
3293 before deleting the data. Otherwise the hash table will have
3294 freed data in comparison functions. Affected file is
3295 silcd/command_reply.c.
3297 * Fixed silc_idlist_replace_client_id to add the new entry to
3298 the cache with NULL nickname. Otherwise there will be invalid
3299 memory as the nickname after the nickname is freed. Affected
3300 file silcd/packet_receive.c.
3302 * Fixed the silc_idlist_get_clients_by_hash. The entries was
3303 saved into wrong slots because the previous number of entries
3304 was not taken into account. Affected file silcd/idlist.c.
3305 Fixed same thing in silc_idlist_get_clients_by_nickname too.
3307 * If we are router and we receive JOIN notify to a channel that
3308 does not have any users then notified client is marked as the
3309 channel founder, as it is it. The affected file is
3310 silcd/packet_receive.c
3312 * Added to the extended hash table API's table_del_*ext functions
3313 the destructor as argument too, so that the caller can decide
3314 which destructor to use or whether to use destructor at all.
3315 Affected file lib/silcutil/silchashtable.[ch].
3317 * Fixed ID Cache purging. It actually deleted the entries from
3318 the hash table after the data was freed. The hash table ended
3319 up comparing freed memory. The affected file is
3320 lib/silccore/silcidcache.c.
3322 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3324 * Fixed Irssi SILC client's KILL command's HELP syntax.
3326 * The USERS command now resolves the detailed user information
3327 if the userinfo field is missing. Affected file is
3328 lib/silcclient/command_reply.c.
3330 * Do not print error in silc_file_read if the read file does
3331 not exist. Just silently return NULL. Affected file is
3332 lib/silcutil/silcutil.c.
3334 * Fixed the silc_log_output to not wine about NULL filename
3335 and to not create some bogus " " filename. Affected file is
3336 lib/silcutil/silclog.c.
3338 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3340 * Fixed various printing bugs on the user interface in the
3341 Irssi SILC Client. Minor changes that were forgotten from
3344 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3346 * Fixed the configure.in.pre and the compilation and distribution
3347 environment to support the new autoconf 2.52. That version is
3348 now required to compile the CVS trunk.
3350 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3352 * Renamed function silc_parse_nickname to silc_parse_userfqdn
3353 to generally parse user@fqdn format strings. Affected file
3354 lib/silcutil/silcutil.c.
3356 * Added nickname_format and nickname_force_format fields to the
3357 SilcClientParams structure. The first one defines the format
3358 for the nicknames that the library will enforce if the receives
3359 multiple same nicknames. The second one is boolean value and
3360 can be used to force the library to always enforce the format
3361 to the nicknames regardles whether there are multiple nicknames
3362 or not. This configurable formatting was employed to flexibly
3363 support accessing multiple nicknames from the user interface.
3364 The userinterface can now set the nicknames to what ever format
3365 they prefer. Affected file lib/silcclient/silcapi.h.
3367 Added function silc_client_nickname_format to the file
3368 lib/silcclient/idlist.c. It performs the nickname formatting.
3370 Added new field `hostname´ to the SilcClientEntry context.
3371 It holds the hostname of the client. Affected file is
3372 lib/silcclient/idlist.h.
3374 * Irssi SILC Client sets the nicknames in nick@hostn format.
3375 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
3376 irssi/src/silc/core/silc-core.c.
3378 The WHOIS printing now also shows both the real nickname and
3379 the formatted nickname so that user knows how to access the
3380 user if there are multiple same nicknames cached. Affected
3381 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
3382 printing formatting too to take the hostname now as a separate
3383 argument. The Affected file is
3384 irssi/src/fe-common/silc/modules-formats.[ch].
3386 * Changed the silc_client_get_clients_local to accept the formatted
3387 nickname as argument. It accepts the real nickname too but the
3388 formatted nickname can be used to find the true entry from
3389 multiple entries. Affected file lib/silcclient/silcapi.h and
3390 lib/silcclient/idlist.c.
3392 * Added nickname_format_parse field to the SilcClientParams.
3393 It is a callback function provided by the application to parse
3394 the nickname out of the formatted nickname string. The library
3395 calls it to get the nickname from the formatted string. Since
3396 the application generally knows better the format of the nickname
3397 string it parses it instead of the library, even though library
3398 encodes the formatted string. If the callback function is not
3399 provided then the library will use the string as is. The
3400 affected file is lib/silcclient/silcapi.h.
3402 * All the nickname strings passed to the client library in
3403 commands are now expected to be formatted nickname strings.
3404 If the command does not support the formatted nickname string
3405 it will assume that the sent string is the actual nickname.
3406 Affected file lib/silcclient/command.c.
3408 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3410 * Added public key authentication support to OPER and SILCOPER
3411 commands in the client library. Affected file is
3412 lib/silcclient/command.c.
3414 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3416 * Changed the get_auth_methdod client operation to be asynchronous.
3417 It can be async if the application resolves the authentication
3418 method from the server during the negotiation. Added new
3419 SilcGetAuthMeth completion callback that the application will
3420 call after resolving the authentication method.
3422 Added function silc_client_request_authentication_method that
3423 the application can use to resolve the authentication method
3424 from the server. Added also SilcConnectionAuthRequest callback
3425 that the library will call after the server has replied. The
3426 application can call this function if it does not know the
3427 current authentication method.
3429 Affected files are lib/silcclient/client.c and
3430 lib/silcclient/silcapi.h.
3432 * The Irssi SILC client now automatically resolves the authentication
3433 method incase any configuration information is not present (and
3434 currently there never is). The affected file is
3435 irssi/src/silc/core/client_ops.c.
3437 * Fixed public key authentication from the client library.
3438 Affected file lib/silcclient/protocol.c. Changed also the
3439 protocol specification about the public key authentication in
3440 the connection authentication protocol. The actual data to be
3441 signed is now computed with a hash function before signing.
3443 * Fixed the public key authentication from the server as well.
3444 Affected file silcd/protocol.c.
3446 * Removed the mlock()'s from the memory allocation routines.
3447 Affected file lib/silcutil/silcmemory.c. The ./configure does
3448 not check anymore for the mlock(). Affected file is
3451 * Fixed USERS command in server to allow the execution of the
3452 command for private and secret channels if the client sending
3453 the command is on the channel. Affected file silcd/command.c.
3455 * Fixed silc_client_get_clients_local to return the clients
3456 count correctly. It could return wrong value. Affected file
3457 lib/silcclient/idlist.c.
3459 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3461 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
3462 types. The assembler optimizations seemed not to like 64-bit
3463 data types. The assmebler optimizations thus are now enabled
3464 also for BSD systems as opposed to only enable them for Linux.
3466 * Do not check for threads at all on BSD systems. Affected
3467 file configure.in.pre.
3469 * Removed -n and -h options from the Irssi SILC Client since
3470 they are not used in silc.
3472 * Fixed the prime generation to assure that the first digit
3473 of the generated random number is not zero since our conversion
3474 routines does not like number strings that starts with zero
3475 digit. If zero digit is seen the random number is regenerated.
3476 This caused some corrupted RSA keys when the zero first digit
3477 was met. Affected file lib/silcmath/silcprimegen.c.
3479 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3481 * Fixed WIN32 configuration in the ./configure script.
3482 Fixed to include xti.h on environments that has it.
3483 Patches by Carsten Ilchmann and andrew.
3485 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3487 * Changed the silc_id_create_client_id to be collision
3488 resistant. It is now assured that there cannot be created
3489 two same client ID's. I suspect that some weird bugs in
3490 the server were actually caused by duplicate Client IDs.
3491 Affected file silcd/serverid.[ch]. A router receiving
3492 new ID now also assures and informs the sending server
3493 if the ID caused collision.
3495 * Changed the silc_id_create_channel_id to also assure that
3496 there are no collisions.
3498 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3500 * Statement about ignoring the Mutual Authentication flag when
3501 performing rekey with PFS was a bit misleading. It is ignored
3502 if it was set in the initial negotiation, it cannot be even
3503 set in the rekey. Fixed in the ke-auth draft. Started the
3504 new versions of the protocol drafts in the doc/.
3506 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3508 * Fixed a bug in silc_client_command_identify_save when saving
3509 new channel information. The channel name was no duplicated
3510 and caused crash on exit. Affected file is
3511 lib/silcclient/command_reply.c.
3513 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3515 * Fixed the getkey command handling in the server. Send just
3516 empty OK reply to the sender if the key could not be fetched
3517 (but everything else was ok, like the key just was not available).
3518 Changed the public key parameter to optional in the protocol
3519 specs so that empty OK reply can be sent. Affected file
3522 Added a message to Irssi SILC client to tell to user if the
3523 server did not return a public key.
3525 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3527 * Fixed a channel key regeneration bug. It registered new
3528 timeout tasks exponentially until all system resources were
3529 used. Affected file silcd/server.c.
3531 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3533 * Added the SILC Document generator to the scripts/silcdoc.
3534 It can be used to generate the Toolkit Reference Manual out
3535 of the source tree. Internally it will also use the RoboDoc
3536 generator now imported in util/robodoc.
3538 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3540 * Added couple of return's in rekey protocol if error orccurred
3541 during the protocol. The execution must be terminated.
3542 Affected file silcd/protocol.c. Also, terminate the protocol
3543 always with timeout.
3545 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3547 * The client's Client ID was created initally from the wrong
3548 nickname (it could have been in format nick@host) in the
3549 silc_server_new_client. Affected file silcd/packet_receive.c
3551 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3553 * Added some SILC_LOG_ERROR's to various error conditions
3554 if client could not be added to ID cache. Affected files
3555 silcd/packet_receive.c and silcd/server.c.
3557 * When client's sock->user_data is freed, NULL also the
3558 client->router and client->connection pointers. Added check
3559 for these pointers being NULL to various places around the
3560 code. Affected file silcd/server.c.
3562 * Added client->data.registered == TRUE checks to various
3563 places around the code to assure that unregistered client's
3564 are not handled when it is not allowed. Affected file
3567 * Added `bool registered' fields to all
3568 silc_idlist_[server|client]_get_* routines to indicate whether
3569 the fetched client needs to be registered or not. Affected
3570 file silcd/idlist.[ch].
3572 * Add your own entry as registered to the ID cache in the
3573 server. Affected file server.c.
3575 * Fixed a bug in silc_server_new_server. The SilcServer was
3576 set as the new server's context instead of SilcServerEntry.
3577 This naturally caused some weird bugs.
3579 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3581 * Do not delete the channel rekey task when adding it
3582 for in silc_server_create_channel_key.
3584 * Changed the silc_server_create_channel_key to return
3585 TRUE or FALSE to indicate the success of the channel key
3588 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3590 * Fixed MSVC++ project files and added missing files to
3591 Makefiles under win32/.
3593 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3595 * Do not add TCP_NODELAY flag if the operating system
3596 does not have it defined. Affected files are
3597 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3599 * Fixed buffer overflow from Irssi SILC Client. Affected
3600 file irssi/src/fe-common/core/themes.c.
3602 * Fixed double free in client library in the file
3603 lib/silcclient/client.c when disconnecting from server.
3605 * Applied double free patch from cras to Irssi SILC client.
3606 Affected files irssi/src/core/[modules/expandos].c
3608 * Fixed the disconnection handling to Irssi SILC Client.
3609 The application must call silc_client_close_connection
3610 in ops->connect client operation in case of failure of
3611 the connection. Affected file is
3612 irssi/src/silc/core/client_ops.c.
3614 * Do not set sock->protocol to NULL in the function
3615 silc_client_close_connection after executing the protocol's
3616 final callback since the sock might not be valid anymore.
3617 Affected file lib/silcclient/client.c.
3619 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3621 * Do not enable SILC_THREADS if the linking with libpthread
3622 did not happen. Affected file configure.in.pre.
3624 * Added notion to protocol specification that server must
3625 verify the sent authentication payload with CMODE when
3626 setting the channel founder key. Implemented it to the
3627 server. Affected file silcd/command.c.
3629 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3631 * Added _EXTRA_DIST SILC distribution variable to the
3632 distributions file. It is used to conditionally add extra
3633 files or directories to the specific distribution. Affected
3634 files ./prepare, Makefile.am.pre and distributions.
3636 Removed the `_' from the start of the distribution names.
3639 * Added README.WIN32 for instructions to compile the Toolkit
3642 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3644 * Fixed a double free in disconnection in the server. Affected
3645 file is silcd/server.c.
3647 * Fixed the lib/silcske/groups.c to work now also with GMP
3648 MP library. The string conversion did not work when using
3649 specific base and the base is indicated in the string as well.
3651 * Created win32/ directory which now includes MSVC++ specific
3652 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3653 It will appear only in the toolkit distribution
3655 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3657 * Changed the key material distribution function in case when
3658 the hash output is too short. The data is now concatenated
3659 a bit differently than it used to. Made the change to the
3660 SKE protocol specification.
3662 * Added better GMP detection to configure.in.pre. A patch
3665 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3667 * Fixed a minor bug in SKE that might cause some problem on
3668 some platforms. Affected file lib/silcske/silcske.c.
3670 * Added the cookie checking for initiator in the SKE. It checks
3671 that the responder returns the sent cookie unmodified. The
3672 affected file is lib/silcske/silcske.c. Added new SKE
3673 error type INVALID_COOKIE that can be sent during the
3674 negotiation. Fixed some memory leaks as well.
3676 * Added the "invalid cookie" error message to Irssi SILC client's
3679 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3681 * Added `task_max' field to the SilcClientParams to indicate
3682 the maximum tasks the scheduler can handle. If set to zero,
3683 default values are used. Affected file lib/silcclient/silcapi.h.
3685 * Fixed memory leaks in silc_client_close_connection. Affected
3686 file lib/silcclient/client.c.
3688 * Added silc_client_del_client_entry to client library to free
3689 all memory of given client entry. Affected file is
3690 lib/silcclient/idlist.[ch].
3692 * Added new functions silc_client_del_channel and
3693 silc_client_del_server to delete channel and server entries.
3694 Affected file lib/silcclient/[silcapi.h/idlist.c].
3696 * Removed silc_client_del_client_by_id from silcapi.h.
3698 * Fixed the INFO command to return the server's own info
3699 correctly when querying by Server ID. Affected file is
3702 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3704 * Removed the non-blocking settings in WIN32 code in the
3705 silc_sock_[read/write] and added SleepEx instead. Affected
3706 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3707 of input data is now checked with FIONREAD and ioctlsocket.
3709 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3711 * Call silc_schedule_task_del_by_context in the
3712 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3713 Affected file lib/silccore/silcprotocol.c.
3715 * Call silc_protocol_cancel for active protocols in the
3716 silc_server_close_connection if the funtion
3717 silc_server_free_sock_user_data has not been called.
3718 Affected file silcd/server.c.
3720 * Generic tasks cannot be deleted using the del_by_fd
3721 task deleting function since generic tasks does not match
3722 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3724 * Added a notion to SILCOPER help file that the SILCOPER works
3725 only on router server, not on normal server.
3727 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3729 * Added for WIN32 support for the new scheduler as well.
3730 Affected file lib/silcutil/win32/silcwin32schedule.c.
3732 * Fixed the SHA1 implementation to work on various platforms.
3734 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3736 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3737 API. It is part of the scheduler now. Everything else is
3738 as previously but some functions has changed their names.
3739 Checkout the lib/silcutil/silcschedule.h for the interface.
3740 Updated all applications to use the new interface. Affected
3741 files are lib/silcutil/silcschedule.[ch].
3743 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3745 * Found a bug in the SKE implementation. The HASH value,
3746 specified by the protocol, was not computed correctly. The
3747 public key of the responder was not added to the computation
3748 even though it is mandatory. Affected file lib/silcske/silcske.c.
3749 This unfortunately causes incompatibilities with older
3750 clients and servers.
3752 * Added WIN32 specific network init and uninit functions:
3753 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3754 the Winsock2. Affected file lib/silcutil/silcnet.h and
3755 lib/silcutil/win32/silcwin32net.c.
3757 * Set the socket always to nonblocking mode on WIN32 after
3758 reading data or writing data. Affected file is
3759 lib/silcutil/win32/silcwin32sockconn.c.
3761 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3763 * Fixed various compilation problems under WIN32. Affected
3764 files lib/silcutil/win32/silcwin32thread.c and
3765 lib/silcutil/win32/silcwin32schedule.c.
3767 * Removed all _internal.h #includes from public header
3768 files. Internal headers must never be included from
3771 Removed also the lib/silcske/payload_internal.h file.
3773 * All include files that may be needed (public and some others
3774 included by the public headers) by application developers are
3775 now copied to the ./includes directory. It does not copy any
3776 internal headers. Affected file Makefile.defines.pre and all
3777 Makefile.am's under lib/ and subdirs.
3779 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3781 * Do not change the ~/.silc directory's permissions automatically.
3782 Affected file irssi/src/silc/core/clientutil.c.
3784 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3786 * Do not cancel the protocol in silc_server_close_connection
3787 it might cause recursion. Now cancelled in the function
3788 silc_server_free_sock_user_data. Affected file silcd/server.c.
3790 * Fixed the silc_server_remove_clients_by_server to regenerate
3791 the channel keys correctly finally. Added also new function
3792 silc_server_remove_clients_channels to actually do it.
3793 Affected file silcd/server.c.
3795 * Fixed the silc_server_new_channel to not crash by giving
3796 wrong router to the new channel. Affected file is
3797 silcd/packet_receive.c.
3799 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3801 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3802 which is given as argument to the silc_client_alloc now.
3803 It can be used to configure the client and set various parameters
3804 that affect the function of the client.
3806 * The USERS command in server did not check whether the channel
3807 is private or secret. Affected file silcd/command.c.
3809 * Added new argument to the USERS command in protocol specification.
3810 The USERS command now can take the channel name as argument
3811 as well. Added support for this in client and server and
3812 updated the protocol specs.
3814 * Completed the GETKEY command in client. It can be now used
3815 to fetch also servers public key not only some clients.
3816 Affected files lib/silcclient/command[_reply].c.
3818 * Added silc_client_get_server to return server entry by the
3819 server name. Affected files lib/silcclient/silcapi.h and
3822 * Redefined the IDENTIFY command in protocol specification to be
3823 more generic. It now can be used to query information about
3824 any entity in the SILC Network, including clients, servers and
3825 channels. The query may be based either the entity's name
3826 or the ID. Added support for this in both client and server.
3828 Affected files silcd/command.c and lib/silcclient/command.c
3829 and command_reply.c.
3831 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3832 the _from_client and _from_server functions. Affected file
3835 * Added silc_client_get_channel_by_id_resolve to the file
3836 lib/silcclient/silcapi.h to resolve channel information by
3837 its ID. Added also silc_client_get_channel_by_id that
3838 does not resolve it from the server.
3840 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3842 * Added SilcServerEntry context into the client library
3843 to represent one server. The INFO command now allocates
3844 these to save the resolved server info. For now on the
3845 client library will also keep information about servers,
3846 connected and resolved with INFO.
3848 The INFO command now allocates the SilcServerEntry context
3849 and saves the server info there. The COMMAND_REPLY in
3850 the INFO now returns the parameters to application in
3851 same order as defined in the protocol specification.
3853 The entries are cached in the client->server_cache.
3855 * The INFO command is now issued after received the Client ID
3856 from the server. Affected file lib/silcclient/client.c.
3858 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3859 to the application as the mode changer might be server.
3860 It is guaranteed that NULL is not returned anymore to the
3861 application. Affected file lib/silcclient/client_notify.c.
3863 The ID Type is now also passed to the application so that
3864 it can check whether the returned entry is SilcClientEntry
3867 Added new function silc_client_get_server_by_id to return
3868 the server entry by ID. Affected files are the
3869 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3871 * Do not create the channel in the Irssi SILC Client when issuing
3872 the JOIN command but when received the sucessful JOIN command
3873 reply. Otherwise the channel might get created even though we
3874 could not join it. The Affected file is
3875 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3877 * Fixed a channel joining bug in router. The router must also
3878 check the channel modes, invite and ban lists etc. when serving
3879 the JOIN command sent by normal server. Affected file is
3880 silcd/command.c. The router now resolves the client's
3881 information from the server who sent the JOIN command if it
3882 does not know it, and processes the JOIN command only after
3885 * Changed the SilcCommandCb to take new argument; void *context2.
3886 Affected file lib/silccore/silccommand.h
3888 The second argument in the command callbacks in the server now
3889 includes the SilcServerCommandReplyContext if the command was
3890 called as pending command callback from the command reply.
3891 Otherwise it is NULL. When called as pending the status of the
3892 command reply will be checked and if it was erronous the
3893 error will be sent to the original sender of the command.
3894 This way the client always receives the error messages even
3895 though the server was actually the one who received the error
3896 when it resent the command to router, for example. Affected
3897 files silcd/command[_reply].[ch].
3899 * Fixed sending WHOWAS command's error message to client if
3900 the requested client could not be found. It was missing.
3903 * Changed the CMODE and CUMODE commands reply arguments in the
3904 protocol specification. The Channel ID is now sent in both
3905 of the commands to identify the channel. Implemented this
3906 new feature to the client and server. Affected files
3907 lib/silcclient/command_reply.c and silcd/command.c.
3909 * Made better checks for invite and ban lists in the JOIN
3910 command in server. Affected file silcd/command.c.
3912 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3914 * The server now performs the incoming host IP/DNS lookup
3915 using the silc_socket_host_lookup and thus does not block
3916 the server anymore. Affected file silcd/server.c.
3918 * Completed the multi-thread support for SILC Scheduler in
3919 the lib/silcutil/silcschedule.c.
3921 * Fixed the configure.in.pre to detect the pthread correctly
3924 * Fixed a deadlock in silc_task_queue_wakeup in the file
3925 lib/silcutil/silctask.c.
3927 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3929 * Added new function silc_schedule_wakeup that is used in
3930 multi-threaded environment to wakeup the main thread's
3931 schduler. It needs to be used when a thread adds a new task
3932 or removes a task from task queues. After waking up, the
3933 scheduler will detect the task queue changes. If threads
3934 support is not compiled in this function has no effect.
3935 Implemented the wakeup mechanism to both Unix and WIN32
3936 systems. Affected files are lib/silcutil/silcschedule.[ch],
3937 lib/silcutil/unix/silcunixschedule.c and the
3938 lib/silcutil/win32/silcwin32schedule.c.
3940 * Added new function silc_task_queue_wakeup to wakeup the
3941 scheduler by the specified task queue. Affected file
3942 lib/silcutil/silctask.[ch].
3944 * The silc_socket_host_lookup_start now wakes up the scheduler
3945 after adding the timeout task. Affected file is
3946 lib/silcutil/silcsockconn.c.
3948 * The silc_socket_host_lookup is synchronous now if the threads
3949 support is not compiled in. However, the callback is still
3950 called asyncronously through the scheduler, anyway. Affected
3951 file lib/silcutil/silcsockconn.c.
3953 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3955 * Added new function silc_socket_host_lookup to perform
3956 asynchronous IP and FQDN lookups for the socket connection.
3957 Affected files lib/silcutil/silcsockconn.[ch].
3959 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3961 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3962 that may or may not compile the mutex support in.
3964 Changed the silc_mutex_alloc interface. It allocates the
3965 mutex now to the sent pointer and returns TRUE or FALSE.
3967 Affected file lib/silcutil/silcmutex.h.
3969 * Wrote the SILC Task Queue interface to support multi-threads.
3970 Affected file lib/silcutil/silctask.[ch].
3972 * Wrote the SILC Scheduler to support multi-threads. Affected
3973 file lib/silcutil/silcschedule.c.
3975 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3977 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3978 in lib/silcutil/win32/.
3980 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3982 * Defined SILC Mutex API and SILC Thread API and implemented
3983 them for Unix. Affected files are
3984 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3985 lib/silcutil/unix/silcunixmutex.c and
3986 lib/silcutil/unix/silcunixthread.c.
3988 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3990 * Fixed the silc_server_remove_clients_by_server's channel
3991 key re-generation. The hash table handling was incorrect
3992 and would not work with many channels. Affected file is
3995 * Fixed some memory leaks around the server code.
3997 * Rewrote the silc_server_get_users_on_channel to support IPv6
3998 based Client ID's. Affected file silcd/server.c.
4000 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
4001 specification. However, a separate document must be written
4002 to define the detailed signing procedure and the payload
4003 associated with the flag. Defined the flag to the
4004 lib/silccore/silcchannel.h as well.
4006 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4008 * Changed the dynamic tables to static size tables in the
4009 lib/silccrypt/silchmac.c.
4011 * Removed GCC dependencies from the code. A patch by cras.
4013 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4015 * Do not show the error "Error receiving packet bla bla"
4016 in server if it really was not an error (-2 means that reading
4017 is pending). Affected file silcd/server.c.
4019 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4021 * Fixed a possible crash in silc_server_remove_clients_by_server
4022 in silcd/server.c. Fixed there also some memory leaks.
4024 * Fixed the silc_idlist_replace_client_id. It could replace
4025 wrong key in the hash table. Affected file silcd/idlist.c.
4027 * Do not check whether there are global users on the channel
4028 if the channel->global_users is FALSE. Affected functions
4029 silc_server_remove_from_one_channel and
4030 silc_server_remove_from_channels in silcd/server.c. Also,
4031 do not check if the removed client is local as we can be
4032 sure that global client was not removed from the channel
4033 and checking for global users is not needed.
4035 * The silc_server_remove_clients_by_server now re-generates
4036 the channel keys correctly for those channels that had
4037 clients removed from them. Affected file silcd/server.c.
4039 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4041 * Found the reason of random crashes in the server. We weren't
4042 ignoring the SIGPIPE signal (which can be sent in write())
4043 and it crashed the server. Affected file silcd/silcd.c.
4045 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4047 * Assure that sock->user_data is not NULL in the function
4048 silc_server_packet_send in silcd/packet_send.c.
4050 * Disconnect the remote connection if it could not be added
4051 to any ID lists in the server. The affected file is
4054 * Check in silc_server_packet_send[_real/dest] that the
4055 socket is not disconnecting and ignore the data if it is.
4056 Affected file silcd/packet_send.c.
4058 * Define inline to __inline on native WIN32 compilation.
4059 Affected file includes/silcwin32.h.
4061 * Added some explicit type casts for inline code since MSVC
4062 require them. Affected files lib/silcutil/silcbuffer.h,
4063 lib/trq/silcdlist.h and lib/trq/silclist.h.
4065 * Print warning in log files from now on if the packet
4066 decryption fails. Affected file silcd/server.c.
4068 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4070 * Changed the `say' client operation's interface to accept
4071 new `type' argument to indicate the type of the message sent
4072 by the library. The application may filter the library's
4073 messages according the type. The affected file is the
4074 lib/silcclient/silcapi.h.
4076 * Added two new functions to lib/silcclient/silcapi.h:
4077 silc_client_del_client and silc_client_del_client_by_id.
4078 Affected file lib/silcclient/idlist.c.
4080 * Moved the clientincludes.h from includes/ to silc/ and
4081 serverincludes.h from includes/ to silcd/.
4083 * The modes for the CMODE and CUMODE are now passed as
4084 uint32 for application with COMMAND_REPLY. The affected
4085 file is lib/silcclient/command_reply.c.
4087 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4089 * /WHOIS without arguments shows client's own information.
4090 Affected file lib/silcclient/command.c.
4092 * Changed PING to not accept any arguments. The specs
4093 says that client can ping only the connected server so
4094 requiring an argument is not needed. Affected file is
4095 lib/silcclient/command.c.
4097 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4099 * Fixed a fatal bug in private message sending and reception
4100 encryption and decryption when using private message keys.
4101 The implementation was incorrect and did not follow the
4102 specification. It causd that some of the message were
4103 lost since it did not use the sending and receiving keys
4104 as the protocol suggests. This has been fixed and will cause
4105 incompatibilities with older clients when sending private
4106 message encrypted with private message keys. Affected files
4107 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
4108 and various other in Irssi SILC Client.
4110 Added `responder' boolean argument to the functions
4111 silc_client_add_private_message_key[_ske] to indicate when
4112 the key is added as responder or initiator of the key
4115 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4117 * Removed the silc_ske_check_version function and created
4118 a SilcSKECheckVersion callback. Added also a function
4119 silc_ske_set_callbacks that is now used to set all SKE
4120 callbacks. The callback functions are not given to
4121 the SKE functions anymore, but this function is used to
4124 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
4126 * Added `silc_version' argument to the silc_client_alloc
4127 to define the version of the application for the library.
4128 The library will use the version string to compare it
4129 against the remote host's (usually a server) version
4130 string. Affected file lib/silcclient/silcapi.h
4132 * Added the KE protocol context to Key Agreement context
4133 in client library so that we can abort the SKE if it
4134 is in process when we get timeout. Affected file is
4135 lib/silcclient/client_keyagr.c.
4137 * Do not resolve the client ID forever if it returns in the
4138 first time that such client does not exist. This was done
4139 for example with private message. Affected file is
4140 lib/silcclient/client_prvmsg.c.
4142 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4144 * Do not add regex.h for WIN32. The affected file
4145 includes/silcincludes.h.
4147 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
4148 not work yet 100%. It generates the DLL's automatically
4149 when compiling with --with-win32 under cygwin.
4151 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4153 * lib/contrib/regex.c is not compiled on WIN32.
4155 * Added silc_net_get_socket_opt function to the
4156 lib/silcutil/silcnet.h.
4158 * Added includes/silcwin32.h for WIN32 specific includes
4161 * Do not use ptime structure or any of the posix process
4162 functions on WIN32 in lib/silccrypt/silrng.c.
4164 * Added silc_gettimeofday to provide generic function
4165 for struct timeval on all platforms. Added the function
4166 to lib/silcutil/silcutil.h.
4168 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4170 * Moved the lib/silccore/silcsockconn.[ch] to the utility
4171 library as they clearly belong there. As a plus side we
4172 can make the actual socket connection routines platform
4175 Added also new generic function silc_socket_read and
4176 silc_socket_write (that used to be silc_packet_[read/write].
4177 The implementation of these are platform specific.
4179 * Added WIN32 specific routines of silc_socket_[read/write]
4180 to lib/silcutil/win32/silcwin32sockconn.c.
4182 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4184 * Added preliminary support for native WIN32 compilation under
4185 cygwin (using the -mno-cygwin option for GCC) to the
4186 ./configure.in.pre. The --with-win32 now prepares the
4187 compilation for native WIN32.
4189 * Rewrote the SILC Scheduler interface in the file
4190 lib/silcutil/silcschedule.h. The scheduler is now context
4191 based and does not have anymore any global static scheduler.
4192 Moved the Unix scheduler to the lib/silcutil/unix/ directory
4193 and created lib/silcutil/win32 directory for WIN32 based
4196 * Added Unix specific network routines to the
4197 lib/silcutil/unix/silcunixnet.c and the old
4198 lib/silcutil/silcnet.c includes now only generic routines.
4200 Added WIN32 specific network routines to the
4201 lib/silcutil/win32/silcwin32net.c.
4203 * Added Unix specific utility functions from the
4204 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
4206 * Added WIN32 SILC Scheduler to the file
4207 lib/silcutil/win32/silcwin32schedule.c. The code is of course
4210 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4212 * Do not handle JOIN notify in the server if the target client
4213 is not registered (idata->registered == FALSE). The affected
4214 file is silcd/packet_receive.c.
4216 * Update the nickrec->founder in event_cumode in the Irssi SILC
4217 client. Affected file irssi/src/silc/core/silc-channels.c.
4219 * Fixed the CUMODE_CHANGE notify handling in the server when
4220 server and router are announcing their clients on channels.
4221 Now the mode changes are saved and notified correctly. The
4222 affected file is /silcd/packet_receive.c.
4224 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
4225 They really did not replace the cache entry in the ID Cache.
4226 Now they do that. Affected file silcd/idlist.c.
4228 * Fixed the KICK notify handling in the Irssi SILC client to
4229 update the channel records so that the kicked client does not
4230 appear to be on the channel. The affected file is
4231 irssi/src/silc/core/silc-channels.c.
4233 * Always update the conn->current_channel when executing command
4234 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
4236 * Fixed the KILL notify handling in Irssi SILC client to remove
4237 the killed client on all channels.
4239 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4241 * Fixed the silc_parse_command_line to remove extra spaces
4242 from the start and end of the arguments. Affected file is
4243 lib/silcutil/silcutil.c.
4245 * Cancel and free any active protocol in the function
4246 silc_server_close_connection. Affected file silcd/server.c.
4248 * Cancel and free any active protocol in the function
4249 silc_client_close_connction. Affected file is
4250 lib/silcclient/client.c.
4252 * Do not execute the KILL command for clients that are in
4253 history (ie. they are not in the network). Affected file is
4256 * Fixed KILL notify handling, client does not crash anymore.
4257 Affected file irssi/src/silc/core/silc-channels.c.
4259 * Reduced the default packet buffer size from 2048 to 1024 in
4260 lib/silccore/silcpacket.c.
4262 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
4263 counter to the SKE context that is incresed when the SKE library
4264 performs async operation outside the library. If the outside
4265 process frees the SKE context and FREED status will be set
4266 and the library will detect after the sync operation that the
4267 libary is freed. The affected files are
4268 lib/silcske/silcske[_status].[ch].
4270 * Resolve the client entry information in the function
4271 silc_client_channel_message to assure that NULL pointer is not
4272 passed as client entry to the application. */
4274 * Fixed the task timeout calculation to assure that there is
4275 never negative timeouts. The affected file is
4276 lib/silcutil/silcschedule.c.
4278 * Fixed the channel user mode notification sending in server.
4279 It was sent point-to-point to the router (or to server by router)
4280 but it needs to be destined to a channel. The routines now
4281 supports sending the channel user mode notifys to the channels
4282 when announcing clients and channels. Affected files are
4283 silcd/server.c and silcd/packet_receive.c.
4285 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
4286 It did not actually replace the old channel entry in the cache.
4287 Affected file lib/silcclient/client_notify.c.
4289 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4291 * Fixed a possible crash in silc_packet_send_prepare. It now
4292 assures always that there is enough space in the buffer and
4293 at the tail area of the buffer (for MAC).
4295 Fixed the inbound buffer reallocation in silc_packet_read.
4296 It was old code and did not handle the reallocation correctly.
4299 The affected file is lib/silccore/silcpacket.c.
4301 * Fixed buffer overflow in silc_parse_nickname in the file
4302 lib/silcutil/silcutil.c.
4304 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4306 * make install generates new server keys only if there is not
4309 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4311 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
4312 Added check that if the NOREPLY is set then we will not send
4313 the away message. This avoids infinite loop of away messages
4314 if both clients are away. The affected file is
4315 lib/silcclient/client_prvmsg.c.
4317 * Fixed client crash if /NICK was given without arguments.
4318 Affected file lib/silcclient/command.c.
4320 * Server does not send the invite list in INVITE command back
4321 to the client if the list was not altered. Added this notion
4322 to the protocol spec as well. Affected file silcd/command.c.
4324 Fixed possible crash in INVITE command by checking the
4325 value of silc_server_get_client_route command.
4327 * Fixed the INVITE notify type handling. The arguments are now
4328 taken in correct order and client does not crash. The affected
4329 file is irssi/src/silc/core/silc-channels.c.
4331 Removed the "Inviting xxx to channel" message from the
4332 client library away and let the application handle it.
4333 Affected file lib/silcclient/command.c. Added that message
4334 to Irssi SILC client's message formats.
4336 * Fixed CMODE command crash in client. It now checks the
4337 amount of arguments correctly and does not crash. The affected
4338 file is lib/silcclient/command.c.
4340 * Do not create new channel automatically in silc_channels_join
4341 but check whether the channel by that name already exists.
4342 Affected file irssi/silc/core/silc-channels.c.
4344 * Do not send the SERVER_SIGNOFF to router if the disconnected
4345 entity was the router. Affected file silcd/server.c.
4347 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
4348 SILC client as it was missing from there.
4350 Added the handling of the KICK notify to the Irssi SILC client
4351 as it was missing. Added "you have been kicked" message to
4352 Irssi SILC client's message modules formats.
4354 Added the handing of the KILL notify to the Irssi SILC client
4355 as it was missing. Added the kill message module formats
4358 The affected file is irssi/src/silc/core/silc-channels.c.
4360 * The router did not save the channel mode the server announced.
4361 Affected file silcd/packet_receive.c.
4363 * Fixed a possible crash in INFO command in server. If the
4364 server did not provide the server info it crashed. Affected
4365 file silcd/command.c.
4367 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4369 * Fixed the GETKEY command in the server to check also the
4370 global list. Otherwise the GETKEY would not work correctly
4371 in normal SILC server. Affected file silcd/command.c.
4373 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4375 * Fixed GETKEY crash, it crashed if the command did not succseed.
4377 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4379 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
4380 is now real and not just an macro interface to GMP.
4382 Removed the entire GMP from the source tree and imported new
4383 NSS MPI library instead. Reason for removing GMP is that it is
4384 extremely large and compiles extremely slow. The NSS MPI
4385 is only a few files and compiles in less than 10 seconds.
4386 The speed is also about the same as GMP. The MPI is imported
4387 to lib/silcmath/mpi.
4389 If the system has GMP installed we will still use the GMP.
4390 If it is not then the NSS MPI will be compiled.
4392 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4394 * Merged a long nickname (127 characters long) crash bugfix from
4395 Irssi CVS tree. Affected file irssi/src/core/misc.c.
4397 * Merged a freed memory reference bugfix from Irssi CVS tree.
4398 Affected file irssi/src/core/commands.c.
4400 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4402 * Added the server's public key sving and verification to the
4403 server when performing the SKE. This was missing and the
4404 remote server's (or router's) public key was accepted without
4405 checking whether we have it previously or trust it at all.
4406 Affected file silcd/protocol.c.
4408 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4410 * Check in the silc_server_timeout_remote if protocol is active
4411 and make sure that the protocol's final callback is called so
4412 that all memory if freed. Affected file silcd/server.c.
4414 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4416 * silc_server_whois_send_reply crashed the server if the nickname
4417 was 127 characters long. Affected file silcd/command.c.
4419 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4421 * Added sanity check to the silc_server_new_client. If the hostname
4422 is provided inside username then check that the provided hostname
4423 really is the same as the resolved one. If the hostname was not
4424 resolved then check it from the public key. Affected file is
4425 silcd/packet_receive.c.
4427 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
4428 if the server disconnected us and the connection is not valid
4429 anymore. Affected file irssi/src/silc/core/silc-channels.c.
4431 * Moved the silc_client_[chmode|chumode|chumode_char] away from
4432 the library to the lib/silcutil/silcutil.[ch].
4434 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4436 * Close log file after open. Affected file
4437 lib/silcutil/silclog.c.
4439 * Check whether sock == NULL in silc_client_send_packet and return
4440 if it is. Affected file lib/silcclient/silcclient.c.
4442 * Check rec->entry == NULL in the Irssi SILC Client before
4443 sending the channel message. Affecte file is
4444 irssi/src/silc/core/silc-servers.c.
4446 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4448 * Merged a splitted window bugfix from Irssi CVS tree. The
4449 affected file is irssi/src/fe-text/textbuffer-view.c.
4451 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
4452 It did not print nickname.
4454 * Improved the distributions system a bit.
4456 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4458 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
4459 irssi/src/fe-text/gui-window.c.
4461 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
4462 to in-active server. The affected file is
4463 irssi/src/silc/core/client_ops.c.
4465 * Resolve the client in USERS command reply if the entry does
4466 not have username resolved. The affected file is
4467 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
4468 command to WHOIS command to really resolve stuff. The USERS
4469 is not used any more in any critical section so WHOIS can
4470 be used even though it might be slower than IDENTIFY.
4472 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
4475 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4477 * Changed the protocol API a bit more consistent in the
4478 lib/silccore/silcprotocol.[ch].
4480 * Changed the following headers to ROBODoc format:
4482 lib/silccore/silcpayload.h
4483 lib/silccore/silcprotocol.h
4484 lib/silccore/silcsockconn.h
4486 All core library headers are now formatted.
4488 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4490 * Fixed a bug in Irssi SILC client; do not show that you are
4491 server/router operator if you really are not. Affected file is
4492 irssi/src/silc/core/client_ops.c.
4494 * Renamed silc_command_free_payload to silc_command_payload_free.
4495 Affected file lib/silccore/silccommand.h
4497 * Added silcmath.h to include the prototoypes of various routines
4498 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
4501 * Changed the following headers to ROBODoc format:
4503 lib/silccore/silcchannel.h
4504 lib/silccore/silccommand.h
4505 lib/silccore/silcid.h
4506 lib/silccore/silcidcache.h
4507 lib/silccore/silcmode.h
4508 lib/silccore/silcnotify.h
4509 lib/silccore/silcpacket.h
4510 lib/silcmath/silcmath.h
4512 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4514 * Added checking to the server code not to start the server if
4515 ciphers and stuff are not configured properly. Affected files
4516 silcd/serverconfig.[h] and silcd/server.c.
4518 * Changed the layout of the header files of the public interfaces
4519 in the SILC libraries. The new layout supports ROBODoc
4520 documentation tool (and some others) so that it is easy to create
4521 a library reference manual. All the other headers and source
4522 code must still follow the CodingStyle document. Also source
4523 code must not include these ROBODoc stuffs, only the headers.
4524 Furthermore, all public interface headers must now be named
4525 by using `silc' prefix, example: silcapi.h, silccipher.h.
4526 Some files were renamed due to this. All the other headers
4527 must not be used as public interfaces. I will update the
4528 CodingStyle document later. Changed following headers, so far:
4530 lib/silcclient/silcapi.h
4531 lib/silccore/silcauth.h
4532 lib/silccore/silcprivate.h
4533 lib/silccrypt/silcdh.h
4535 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4539 * Removed silc_client_packet_send_flush from the client library
4540 as it is not needed. Affected file lib/silcclient/client.[ch].
4542 * Added printing of message of unresolved authentication method
4543 to the Irssi SILC client. Added it to the module formats.
4544 Removed the same message from the client library.
4546 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4548 * Added new distribution feature, DISTLABEL. Every distribution
4549 can define own preprocessor label that can be used in the
4550 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
4551 file distributions, acconfig.h.pre and prepare.
4553 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4555 * Added Makefile.defines_int to include the actual definitions
4556 for Makefile.defines.in. Tested the new distribution system,
4557 created distributions and tested installation.
4559 * Added AWAY message printing to the Irssi SILC client. Added
4560 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
4562 * Added SCONNECT command to call the SILC's CONNECT command.
4563 Cannot use CONNECT directly since Irssi uses that internally.
4564 Affected file irssi/src/silc/core/silc-servers.c.
4566 Added ACTION local command. It is same as ME command but takes
4567 the channel as mandatory argument.
4569 Rewrote some of the Irssi's help files to suite for SILC
4572 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4574 * Added Makefile.defines[.in] that should for now on be included
4575 in all Makefile.am file in the source tree. That file includes
4576 all common compilation definitions for SILC source tree.
4578 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4580 * Minor changes to the ./prepare script to change the package
4581 name according the distribution name to the configure.in.
4583 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4585 * Created new distribution system. Added file `distributions'
4586 that defines all the distributions that can be created out of
4587 the SILC source tree. The ./prepare script now reads that
4588 file to determine how to prepare the distributions. The
4589 first argument to the ./prepare is the name of the distribution
4590 and second is the version of the distribution. If given
4591 without arguments it creates the default (toolkit) distribution
4592 with the default version (defined in ./prepare).
4594 All Makefile.am files that are subject to the distributions
4595 are now named as Makefile.am.pre. These are ./Makefile.am
4596 and lib/Makefile.am. Others may be changed later.
4598 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4600 * Added invite list, ban list, some key management and connection
4601 error message printing to module formats in the Irssi SILC client.
4603 * Added new silc_client_set_away_message to set the away message
4604 that is back to the person who sent private message. The
4605 affected file lib/silcclient/silcapi.h and the
4606 lib/silcclient/client_prvmsg.c.
4608 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4610 * Fixed the private message sending in the Irssi SILC client,
4611 added local command KEY to the Irssi SILC client.
4613 Added key management and key agreement message formats to the
4614 irssi/src/fe-common/silc/module-formats.[ch].
4616 Added USERS (alias WHO) printing, server/router operator
4617 indication and LIST command printing to the module formats.
4619 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4621 * Fixed channel joining notify handling, cumode notify handling
4622 from Irssi SILC client.
4624 * Added SILC specific module-formats to the Irssi SILC client so
4625 that SILC specific message hilighting, colors etc is possible.
4626 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4628 Added channel mode, channel user mode, actions, notices,
4629 whois and whowas printing to the the module-formats.c.
4631 * Fixed a bug in channel deletion in the server. The channel
4632 is not left to the cache even if the channel founder auth mode
4633 is set when there are no users anymore on the channel. Affected
4634 file silcd/server.c.
4636 * The silc_net_localhost now resolves the entire hostname including
4637 the domain name. Affected file lib/silcutil/silcnet.c.
4639 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4641 * Changed the ask_passphrase client operation to be ascynchronous.
4642 It has now a completion callback and a context that the
4643 application must call after it has got the passphrase from
4644 the user. Affected files lib/silcclient/silcapi.h,
4645 lib/silcclient/protocol.c, lib/silcclient/command.c and
4648 Added SilcAskPassphrase callback that the application calls
4649 to deliver the passphrase to the library.
4651 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4652 The public key verification and especially a certificate
4653 verification is asynchronous procedure.
4655 Added new SILC_SKE_STATUS_PENDING status to indicate the
4656 request is pending and a callback will be called to finalize
4659 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4660 indicate that remote end did not send its public key (or
4661 certificate), even though we require it. Added check for this
4662 condition in the SKE. This was a security bug, now fixed.
4664 Defined new SilcSKEVerifyCbCompletion callback that is called
4665 when the verification process is completed.
4667 The affected files lib/silcske/silcske_status.h and
4668 lib/silcske/silcske.[ch].
4670 * Changed the verify_public_key client operation to be async
4671 as well. Defined SilcVerifyPublicKey callback that is used to
4672 indicate the success of the public key verification process.
4674 Changed the server and client to use the new async client
4677 * Changed the Irssi SILC client's internal scheduler to be called
4678 twice as many times as it used to be. As a result the client
4679 should be a bit faster now. Affected file is
4680 irssi/src/silc/core/silc-core.c.
4682 * Added support to Irssi SILC client of asynchronous public key
4683 verification and passphrase inquiry. Affected file is
4684 irssi/src/silc/core/silc-core.c.
4686 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4688 * Do not say "You have left channel %s" in client library.
4689 Moved it to the application. Affected files are
4690 lib/silcclient/command.c and silc/client_ops.c.
4692 * Fixed silc_client_get_clients. Command context was not
4693 duplicated and was freed memory in the callback. Affected
4694 file lib/silcclient/idlist.c.
4696 * Do not say "you are now talking..." on JOIN command in the
4697 client library. The appliation must handle it.
4699 * Do not say ".. changed topic to" in command reply in the
4700 client libary. The application must handle it.
4702 * Fixed TOPIC command sending in the client library.
4704 * Fixed a memory leak in silc_client_command_free in the file
4705 lib/silcclient/command.c.
4707 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4709 * Imported a modified version of Irssi client to the source tree.
4710 The Irssi will be used to create a new client called
4711 Irssi SILC. Imported to irssi/.
4713 Added silc_core_init_finish function to the Irssi. Affected
4714 file irssi/configure.in.
4716 A lot changes in the Makefile.ams around the irssi tree.
4718 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4720 * Do not rehash if the new size is same as the old size of the
4721 hash table, in the silc_hash_table_rehash*. The affected file
4722 lib/silcutil/silchashtable.c.
4724 * Replaced hash_table_del_by_context calls from the server
4725 (when channel->user_list and client->channels) to the
4726 hash_table_del as it is sufficient and faster.
4728 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4730 * Added silc_hash_table_list, silc_hash_table_get and the
4731 SilcHashTableList structure to provide an alternative way to
4732 traverse the hash table. The affected files are
4733 lib/silcutil/silchashtable.[ch].
4735 * Changed the server's idlist routines to use the hash table
4736 routines to optimize the code.
4738 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4740 * Replaced the client entry's `channel' list and channel entry's
4741 `user_list' list to hash tables for optimized lookup. Changed
4742 the code to use the hash table interface around the code.
4743 Affected file lib/silcd/idlist.[ch].
4745 * Added `auto_rehash' boolean argument to the function
4746 silc_hash_table_alloc to indicate whether the hash table should
4747 auto-rehash when it thinks is appropriate time. It will
4748 increase the hash table size if the there is twice as much
4749 entries in the table than the size of the table, and will
4750 decrease the size if there are twice as less entries than
4751 the size of the table.
4753 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4755 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4757 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4759 * silc_idcache_purge_by_context deletes the entry now by context
4760 as it is supposed to do. Affected file lib/silccore/idcache.c.
4762 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4763 client is not anymore valid (WHOWAS givens the info) and not
4764 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4766 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4768 * Removed the `data' and `data_len' arguments from the ID Cache
4769 interfaces and added `name' argument. ID Cache does not handle
4770 anymore the binary data only a names associated with given ID.
4772 * When hashing a Client ID with silc_hash_id the entire ID is
4773 not hashed anymore, instead only the hash of the Client ID is
4774 hashed. This way we can access the Client ID from the cache
4775 with Client ID but with the hash of the ID (which is a hash of
4776 the nickname) as well without any difference in performance.
4778 Added also silc_idcache_find_by_id_one_ext to do one on one
4779 searching when we have the actual ID. Added also function
4780 silc_hash_client_id_compare. The affected files are
4781 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4783 * When hashing the name associated with a ID it is always done
4784 in lowercase. This way we can access the cache without worrying
4785 about case-sensitivity, even though, for example nicknames are
4788 * Fixed a bug in server with channel message sending. It put
4789 wrong ID type as destination ID. The affected file
4790 silcd/packet_send.c.
4792 * silc_idcache_del_by_context now deletes from all hash tables
4793 by context. Affected file lib/silccore/idcache.c.
4795 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4797 * Changed the client library to use the new ID Cache interface.
4798 Changes around the source tree.
4800 * Added silc_hash_table_rehash_ext to rehash with specific
4801 hash function. Affected file lib/silcutil/silchashtable.[ch].
4803 * Added silc_hash_string_compare to compare two strings in the
4804 hash table. Affected file lib/silcutil/silcutil.[ch].
4806 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4808 * Added new function silc_idcache_del_by_context into the
4809 lib/silccore/idcache.[ch].
4811 * Changed the server's ID list routines to use the new ID Cache
4812 interface. Changes around the source tree.
4814 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4816 * Added silc_hash_table_del[_by_context]_ext functions in to the
4817 lib/silcutil/silchashtable.[ch].
4819 Removed silc_hash_table_find_all* routines and added new
4820 silc_hash_table_find_foreach to replace them.
4822 Added silc_hash_table_replace_ext function as extended
4823 replacing function. Separated the simple hash table interface
4824 from the extended hash table interface in the file
4825 lib/silcutil/silchashtable.h.
4827 * Fixed minor bugs and changed it to use some of the new
4828 hash table functions in lib/silccore/idcache.c
4830 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4832 * Added new function silc_hash_table_find_all to return all keys
4833 in the hash table by the specified key. As the hash table is
4834 collision resistant it also makes it possible to have several
4835 duplicate keys in the hash table. This function may be used to
4836 find all of the keys from the hash.
4838 Added user_context arguments to the SilcHashFunction,
4839 SilcHashCompare and SilcHashDestructor to deliver user specified
4842 Added new fuctions silc_hash_table_find[_all]_ext to do
4843 extended lookup with specified hash and compare functions and
4844 specified user contexts.
4846 Added new function silc_hash_table_add_ext to add the key
4847 with specified hash function and user context.
4849 Added new function silc_hash_table_foreach to traverse all
4850 entrys in the hash table. Added SilcHashForeach callback
4853 Added new function silc_hash_table_del_by_context to delete
4854 the entry only if the context associated with the key matches.
4856 Affected files are lib/silcutil/silchashtable.[ch].
4858 * Removed silc_hash_[server/client/channel]_id and added just
4859 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4860 silc_hash_id_compare to compare two ID's using as the hash table
4861 comparison function. Added also silc_hash_data to hash
4862 binary data and silc_hash_data_compare to compare it.
4864 * Removed silc_idlist_find_client_by_hash as it is not needed
4865 anymore. Affected file silcd/idlist.[ch].
4867 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4868 to use internally the SilcHashTable. The new ID Cache is a lot
4869 faster than the old one. Some of the ID Cache interface was also
4870 rewritten and obsolete and stupid functions were removed.
4872 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4874 * Added entry_count field to the SilcHashTable to keep the number
4875 of the entries in the table. Implemented the function
4876 silc_hash_table_rehash. Added new function
4877 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4879 Fixed a minor bug in silc_hash_table_free.
4881 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4882 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4883 into the lib/silcutil/silcutil.[ch].
4885 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4887 * Implemented a collision resistant hash table into the
4888 lib/silcutil/silchashtable[ch]. See the header and the source
4889 for the SilcHashTable API.
4891 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4893 * Merged dotconf version 1.0.2 into lib/dotconf.
4895 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4897 * Do not compile anything in lib/silcsim/* if the SIM support
4898 is not enabled. The tree should now compile without problems
4901 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4903 * Compiled the SILC under cygwin. Compiled and tested briefly
4904 without problems. More tests needed. The SIMs didn't compile
4907 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4909 * Fixed possible crash in silc_get_username in the
4910 lib/silcutil/silcutil.c.
4912 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4914 * Fixed a va_arg in silc/client_ops.c.
4916 * Oops, RC5 routines were named AES and caused some problems
4917 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4919 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4921 * Added new SilcIDIP structure into the lib/silccore/id.h and
4922 replaced the old `ip' fields from all SILC ID's to that type.
4923 This is a step towards IPv6 support.
4925 The silc_id_get_len takes now the ID as an extra argument.
4926 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4927 both IPv4 and IPv6 based ID's.
4929 The affected files are lib/silccore/id.[ch] and other files
4930 around the tree using these routines.
4932 * Removed the ID length arguments in server from various
4933 silc_server_send_notify_* routines -> they are not needed
4936 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4938 * Fixed memory leak in silc_encode_pem_file in the file
4939 lib/silcutil/silcutil.c.
4941 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4943 * Check minor version as well in the SKE. Affected files are
4944 silcd/protocol.c and lib/silcclient/protocol.c.
4946 * Added --identifier option to the server so that an identifier
4947 can be when creating the public key for the server. Affected
4948 file is silcd/silcd.c.
4950 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4951 lib/silccrypt/silcpkcs.c.
4953 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4955 * Register default ciphers and stuff when using -C option with
4956 the server. Affected file sildc/silcd.c.
4958 * Put back the servers public key filename format, it is better
4959 than the new one. For now, the client keys are saved with the
4960 new filename format. The affected file silc/client_ops.c.
4962 * Implemented the Cipher API for the rest of the ciphers that
4963 did not implement it or implemented it the wrong way.
4965 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4967 * Register default ciphers and stuff when using the -S option
4968 in the client. Affected file silc/silc.c. Same also when
4969 creating new key pair with -C option.
4971 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4973 * Fixed the silc_verify_public_key client operation function to
4974 save the public keys differently. The fingerprint is now
4975 used as filename and not the hostname. This way also the
4976 client keys are saved uniquely and not with hostnames. The
4977 affected file is silc/client_ops.c.
4979 * Trimmed the silc_hash_fingerprint function to remove extra
4980 whitespaces from the end of the fingerprint. The affected
4981 file is lib/silccrypt/silchash.c.
4985 * Added silc_cipher_register_default function to register all
4986 default ciphers. It can be used when configuration files
4987 does not exist and the application does not want any specific
4988 ciphers in any specific order.
4990 The SilcDList is now used as silc_cipher_list dynamically
4991 allocated cipher list. Removed the static list all together
4992 and now all ciphers must be allocated to the dynamic list.
4993 The silc_cipher_alloc routine was changed to check only the
4996 All silc_cipher_* routines that used to return int returns
4999 The affected files lib/silccrypt/silccrypt.[ch].
5001 * The same thing was done to silc_hash_* as for silc_cipher_*
5002 routines. Affected files lib/silccrypt/silchash.[ch].
5004 * The same thing was done to silc_pkcs_* as for silc_cipher_*
5005 routines. Affected files lib/silccrypt/silcpkcs.[ch].
5006 Added also silc_pkcs_[un]register[_default] functions.
5007 Removed the data_context from the PKCS API.
5009 * Added silc_hmac_register_default function to register default
5010 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
5011 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
5012 to unregister all hmacs at once.
5014 * Register the default ciphers, hash functions, PKCSs and HMACs
5015 if client's configuration file does not exist. The affected
5018 * The client did not load the hash functions from the SIM
5019 modules at all. Added support for this. Affected file is
5020 silc/clientconfig.c.
5022 * When decoding public key with silc_pkcs_public_key_decode, check
5023 the supported algorithm only if PKCS are registered. Affected
5024 file lib/silccrypt/silcpkcs.c. The same was done with the
5025 silc_pkcs_private_key_decode.
5027 * Fixed the SILC List routines to keep the list always in order.
5028 It used to change the list's order when traversing the list but
5029 not it preserves the order. Affected file lib/trq/silclist.h.
5031 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5033 * Added the client library to use the SilcSocketConnection's
5034 reference counter (by silc_socket_dup) to prevent the bug that
5035 the socket object may be freed underneath async operation.
5037 * The name resolv library checking fixes in the configure.in.pre.
5040 * Created new version of the protocol drafts for future
5041 development. The -03 drafts are the ones that will be changed
5042 in the trunk now and the -02 will remain as they are.
5044 * Send list of CUMODE notifys to the router when announcing
5045 the channel users to the router. Affected file silcd/server.c.
5046 If the router receiving channel founder CUMODE for a channel
5047 that already has channel founder it will send CUMODE notify
5048 to the sender to remove the channel founder rights from the
5049 announced client. Affected file silcd/packet_receive.c.
5051 * The CUMODE notify may now use Server ID as well as the entity
5052 who changes the mode. Updated protocool specs.
5054 * Updated INSTALL and README files.
5056 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5058 * New web pages in the http://silc.pspt.fi. The pages was
5063 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5065 * Implemented the [DenyConnectin] config section in the server.
5066 Added silc_server_config_denied_conn to check whether incoming
5067 connection is denied. Affected file silcd/serverconfig.[ch].
5069 * Do not check the ports when checking the incoming configuration
5070 data if the port is 0, meaning any. Affected file is
5071 silcd/serverconfig.c.
5073 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5075 * Fixed buffer overflow in silc_string_compare in the file
5076 lib/silcutil/silcutil.c.
5078 * Fixed double free in silc_server_command_leave in the file
5081 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5083 * Fixed the version checking in the server. Affected file is
5086 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5088 * Fixed the configuration data fetching when accepting new
5089 connections in the server. Affected file silcd/server.c.
5091 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5093 * Added `sender_entry' argument to the function
5094 silc_server_packet_relay_to_channel so that we can check
5095 whether some destination actually belongs to the same route
5096 the sender belongs (ie, we must not resend the packet to the
5097 sender). Affected file silcd/packet_send.[ch].
5099 * Added `servername' field to the SilcClientEntry in the server
5100 to hold the name of the server where client is from. Affected
5101 file is silcd/idlist.h.
5103 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5105 * Moved the channel message encrypting in the router betwen
5106 router connections from silc_server_channel_message to the
5107 silc_server_packet_relay_to_channel since we want to check
5108 whether we have anybody channel before encrypting anything.
5109 Affected files silcd/packet_[receive/send].c.
5111 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5113 * Fixed the [AdminConnection] server config section to support
5114 multiple entries. Affected file silcd/serverconfig.c.
5116 * Added support into the server to check the validity of the
5117 incoming connection before executing any KE or authentication
5120 * The connection configuration is now saved to the KE and
5121 connection auth protocol contexts and not fetched anymore in
5122 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
5124 * The local hosts listenning address and port is also resolved
5125 now when starting the server. We want to have the socket object
5126 to include the real address and port for the listener. Added
5127 new function silc_net_check_local_by_sock into the files
5128 lib/silcutil/silcnet.[ch].
5130 * Fixed a broadcast bug in server -> do not broadcast if we
5133 * Fixed a routing bug. Do not route broadcast packets ever.
5134 Broadcast packets must be processed always and not routed since
5135 they may be destined to some other host than yourself and thus
5136 would get routed without no good reason. Affected file is
5139 * Added function silc_server_config_is_primary_route to check
5140 whether primary router connection has been configured (a router
5141 configuration that we are initiating). If there is not, we
5142 will assume that there is only two routers in the SILC network
5143 and we will use the incoming router connection as our primary
5144 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
5146 * Changed the order of the broadcasting. Broadcast _after_ the
5147 packet has been processed not before. Affected file is
5150 * Fixed a [ClientConnection] parsing bug. The port was never
5151 parsed correctly thus resulting to port 0. Affected file
5152 silcd/serverconfig.c.
5154 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
5155 argument and did not set the broadcast packet flag. Affected
5156 file silcd/packet_send.c. Fixed same bug in the function
5157 silc_server_send_notify as well.
5159 * If we receive NEW_ID packet for our own ID in the server, ignore
5162 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5166 * Removed the nickname from the Private Message Payload.
5167 Updated the code and the protocol specs.
5169 * Updated protocol specs for submitting to the IETF.
5171 * Tweaked the Random Number Generator a bit. Affected file
5172 lib/silccrypt/silcrng.c. Exported a new function
5173 silc_rng_[global]_add_noise which can be used to add more
5176 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5178 * Do not parse packets with different timeout when protocol
5179 is active -> may cause problem with rekey. Affected file
5182 * When server receives signoff notify it must not create
5183 new channel key if the client is on any channels since the
5184 sender of the signoff notify will create it.
5186 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5188 * Added printing of error messages during SKE protocol from the
5189 failure packet sent by server during SKE. Affected file
5192 * Removed the client's failure_callback handling with timeout
5193 and handle it immediately when received.
5195 * The SKE library returned wrong type in SUCCESS and FAILURE
5196 packets. They must be 32 bit MSB not 16 bit MSB.
5198 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5200 * Ok, rewrote the logic of the re-key and now it seems to work.
5201 I tested it on high traffic with frequent re-keys without
5202 problems. Added hmac_receive (and renamed hmac to hmac_send)
5203 in SilcClientConnection in lib/silcclient/client.h and
5204 in SilcIDListData in silcd/idlist.h. Also, removed the
5205 SilcPacketParserContext's cipher and hmac fields as they are
5206 not needed anymore and actually caused some problems when
5207 the ciphers and hmac's changed underneath the packet parser.
5209 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5211 * If re-key protocol is active then process the incoming packets
5212 synchronously since we must assure that icoming packets encrypted
5213 with the old key is processed before the new keys is set to
5214 use. This is true other packets than for REKEY packets.
5215 Affected file silcd/server.c. The same was done to client library
5216 as well, affected file lib/silcclient/client.c.
5218 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5220 * Fixed bug in client and server to accept the force send if
5221 the packet is send from silc_[server/client]_packet_process
5222 function. Otherwise the packets are never delivered, oops.
5224 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5226 * Disable force sending of packets when REKEY protocol is active.
5227 We must assure that no packet is sent directly when rekey is
5228 performed. All packets must be sent through packet queue.
5229 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
5230 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
5231 function is silc_[server/client]_packet_send_real to check
5234 * Replaced the SIM paths from example config files to
5235 /usr/local/modules. Also, make install creates now
5236 /usr/local/silc/logs directory to hold all the SILC server
5239 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5241 * Made the configure.in.pre work on Solaris. Patch by salo.

5250 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5252 * When MAC computation fails the silc_packet_decrypt returned 0
5253 even though it was supposed to return -1. Fixed this. The
5254 affected file is lib/silccore/silcpacket.c.
5256 * Do not replace the config files in /etc/silc (in make install)
5257 if they already exist. Affected file ./Makefile.am.
5259 * Do not send re-key packets immediately but through packet queue.
5260 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
5262 * Changed silc_net_check_host_by_sock to return FALSE if the
5263 IP/DNS could not be resolved. Though, it returns the IP address
5264 now even if it could not resolve it (but returns also FALSE).
5265 Affected file lib/silcutil/silcnet.[ch].
5267 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5269 * Added silc_pkcs_decode_identifier to decode the public key's
5270 identifier. Affected file lib/silccrypt/silpkcs.[ch].
5271 Added also silc_pkcs_free_identifier. Added also new context
5272 SilcPublicKeyIdentifier.
5274 * Added -S option to the silc client. It is used to dump the
5275 contents of the specified public key file.
5277 * Changed the PKCS api to return the public key length when
5278 setting the public key.
5280 * Fixed a fatal bug in the public and private key file loading.
5281 Affected file lib/silccrypt/silcpkcs.c.
5283 * Execute the packet parsing for client with zero (0) timeout
5284 if the protocol is active. Affected file silcd/server.c.
5286 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5288 * Made the key generation options to the silcd program. Added
5289 -C option, equivalent to client's option.
5291 * Added new [ServerKeys] config section to the server. It
5292 configures the server's public and private key.
5294 * Defined generic Public Key Payload into the protocol
5295 specification to send specific type of public keys and
5298 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
5299 public key or certificate.
5301 * Implemented the GETKEY command to the server and to the
5302 client library and on user interface.
5304 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5306 * Made preliminary `make install' work.
5308 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5310 * Added SilcServerRekey context into silcd/idlist.h.
5312 * Added the PFS support as defined in the specification to the
5313 SKE protocol. Affected files lib/silcske/*.c.
5315 * Added `ske_group' field to the SilcServerRekey context to hold
5316 the number of the SKE group that is used with PFS in re-key.
5317 Affected file silcd/idlist.h.
5319 * Added PFS re-key support to the server. Affected file is
5322 * Added silc_protocol_cancel to cancel execution of the next
5323 state of the protocol. Affected file is
5324 lib/silccore/silcprotocol.[ch].
5326 * Added the re-key support with and without PFS to the client
5327 library. Re-key is performed once in an hour, by default.
5329 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
5330 Added silc_client_rekey_callback and silc_client_rekey_final.
5331 Affected files are lib/silcclient/protocol.[ch] and
5332 lib/silcclient/client.[ch].
5334 * Removed the `hmac_key' and `hmac_key_len' fields from the
5335 SilcClientConnection structure; not needed. Affected file is
5336 lib/silcclient/client.h.
5340 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5342 * Do not ask whether user wants to use the negotiated private key
5343 for private messages, just use it. Affected file is
5344 silc/local_command.c.
5346 * Added `send_enc_key' and `enc_key_len' fields to the
5347 SilcIDListData structure since they are needed in the re-key
5348 phase. Affected file is silcd/idlist.[ch].
5350 * Implemented the simple re-key protocol into the server.
5351 Affected files silcd/server.c and silcd/protocol.[ch]. The
5352 re-key will be performed once in an hour, by default.
5354 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
5355 Added silc_server_rekey, silc_server_rekey_callback and
5356 silc_server_rekey_final.
5358 * Removed Tunneled flag from the protocol. Updated the code
5359 and the specifications.
5361 * Adde `pfs' field to the SilcIDListData to indicate whether
5362 the PFS is to be performed in the re-key. Affected file is
5365 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5367 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
5368 int64 of at least the xintXX size. If void * is less that 4
5369 bytes uint32 * will be used. Defined bool as boolean.
5371 * Changed _ALL_ unsigned long and unsigned int to uint32,
5372 unsgined short to uint16 in the source tree.
5374 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
5375 not handle clients that has entry->data.registered == FALSE.
5376 They are not in the network anymore. Affected file is
5379 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5381 * Implemented the sending of the SERVER_SIGNOFF notify in the
5382 server. Affected file is silcd/server.c.
5384 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
5385 Added also silc_notify_payload_encode_args into the
5386 lib/silccore/silcnotify.[ch].
5388 * Implemented ther SERVER_SIGNOFF notify handling in the server.
5389 Affected file silcd/packet_receive.c.
5391 * Implemented the SERVER_SIGNOFF notify handling in the client
5392 library. Affected file lib/silcclient/client_notify.c. Also,
5393 implemnted the printing of the SERVER_SIGNOFF info to the
5394 application. Affected file silc/client_ops.c.
5396 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
5397 if the deleting was successful. Affected file silcd/idlist.[ch].
5399 * Added support for public key authentication in the connection
5400 authentication protocol in the client library. Affected file
5401 lib/silcclient/protocol.c.
5403 * Changed the server's silc_idlist_get_clients_by_* interface
5404 to support already allocated array so that new entries may be
5405 added to pre-allocated array. Affected file silcd/idlist.[ch].
5406 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
5407 and command replies.
5409 * All command reply functions in the server now calls the
5410 pending command callback even if error occured. This way the
5411 error will be delivered to the client as well. Affected files
5412 silcd/command.c and silcd/command_reply.c.
5414 * Fixed INFO command to return local server's info if no server
5415 was provided. Affected file lib/silcclient/command.c.
5417 * Removed RESTART command for good. Updated the code and the
5420 * Rewrote parts of the task system. It is a bit simpler now.
5421 Removed unsued task priorities. The affected files are
5422 lib/silcutil/silctask.[ch].
5424 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5426 * Moved the USERS printing from the library to the application.
5427 Affected files lib/silcclient/command.c and silc/client_ops.c.
5429 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5433 * Added channel key re-key support. The re-key is perfomed
5434 only by the router and is done once in an hour. Added `rekey'
5435 field to the SilcChannelEntry in the server. Affected files
5436 silcd/server.c and silcd/idlist.h.
5438 * Added silc_task_unregister_by_context into the file
5439 lib/silcutil/silctask.[ch].
5441 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5443 * Added SILC_UMODE_GONE mode to indicate when the client is not
5444 present in the SILC network. Added also support to the local
5445 command AWAY that will set this mode. Added support of showing
5446 "xxx is gone" in WHOIS command. The USERS command shows the
5447 gone status as well.
5449 * Fixed setting server and router operator privileges in the
5450 server's UMODE command. Affected file silcd/command.c.
5452 * Merged the SKE KE1 and KE2 payloads into one payload. The
5453 new KE payload is equivalent to the old KE2 payload.
5455 Cleaned up the SKE Start Payload parsing. It now uses the
5456 simple buffer unformatting to do the parsing. A lot faster
5459 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
5460 to the SKE that is used to indicate whether both of the SKE
5461 parties should perform authentication. By default only the
5462 responder performs authentication. By setting this flag also
5463 the initiator must do authentication. By default it is unset
5464 since in normal SKE case, client to server connection, only
5465 the responder should do authentication. When doing SKE between
5466 two clients both should perform authentication. Updated the
5467 code and the protocol specs.
5469 * A little fix to IDENTIFY command in the server. Search the
5470 client first by hash not nickname. Affected file is
5473 * Fixed the silc_client_close_connection to support closing
5474 the client to client connections wihtout deleting too much
5475 data. Affected file lib/silcclient/client.c.
5477 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
5478 are received if protocol used to be active but is not anymore
5479 the application would crash due to NULL pointer dereference.
5480 Affected files silcd/server.c and lib/silcclient/client.c.
5482 * Added `hash' field to the SilcClientConnection to include
5483 the hash function negotiated in the SKE protocol.
5485 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
5486 to set the channel founder authentication data. A client can
5487 claim the founder rights later by providing the authentication
5488 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
5489 This way the channel founder can regain the channel founder
5490 privileges even it is left the channel. This works only on
5491 local server and the client must be connected to the same
5492 server to be able to regain the founder rights. Updated the
5493 protocol specs accordingly.
5495 Added support to the CMODE command in the client to set the
5496 founder auth data. Read the README to see how to set it.
5498 Added support to the CUMODE command to claim the founder
5499 rights. Read the README to see how to do it.
5501 Added support for the founder authentication to the Channel
5502 Entry in the server. Affected file silcd/idlist.h.
5504 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
5505 server's CMODE command. Affected file silcd/command.c.
5507 * Added the following new functions into lib/silccore/silcauth.[ch]:
5508 silc_auth_get_method and silc_auth_get_data.
5510 * The server now saves the remote hosts public key to the
5511 SilcIDListData pointer. Affected file silcd/protocol.c.
5513 * The normal server now does not remove the channel entry from
5514 the cache if the founder authentication data is set. It used
5515 to remove it if the founder was the last one on the channel on
5516 the server and left the channel. The auth data is saved and
5517 if the channel is re-joined later the old entry is used with
5518 the old auth data. Affected files silcd/command_reply.c and
5521 * Removed the `pkcs' field from the SilcIDListData structure
5522 in the server; it is not used. Affected file silcd/idlist.h.
5524 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5526 * Fixed packet processing on slow links. Partial packets were
5527 never re-processed because the incoming data buffer was cleared
5528 by the application. Application must not directly clear the
5529 sock->inbuf, the packet processing routines handle it. Fixed
5530 this in client library and in server.
5532 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5534 * Fixed the WHOIS and IDENTIFY send reply function to really
5535 check whether to send list or just one entry. Affected file
5538 * Cleaned up the LEAVE command's channel key distribution. The
5539 affected file silcd/command.c.
5541 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
5542 can enforce the channel mode as well. In that case the ID
5543 includes the ID of the server. The code now enforces the
5544 mode change if the router have different mode than the server.
5546 * The notify client operation with CMODE_CHANGE notify can now
5547 return NULL client_entry pointer if the CMODE was not changed
5548 by client. Application must check for this.
5550 * Added <Server ID> argument to INFO command to support server
5551 info fetching by Server ID.
5553 * Added silc_server_announce_get_channel_users to get assembled
5554 packets of channel users of the specified channel. Affected
5555 file silcd/server.[ch].
5557 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
5558 was freed underneath the ID Cache.
5560 * Re-announce clients when the server received CHANNEL_CHANGE
5561 notify from the router. Affected file silcd/packet_send.c.
5563 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5565 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
5566 crashed since it did not handle the fact that there is no cipher
5567 called "3" and didn't check the error condition. Now fixed.
5569 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
5570 flag. It can be used to send message requests.
5572 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5574 * Implemented the RESTART command in the client.
5576 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
5577 notice type messages. Added notice printing to the user
5580 * The channel keys are not re-generated if the channel's mode
5581 is PRIVKEY, ie private key on the channel exists. Affected
5582 files silcd/server.c and silcd/command.c.
5584 * Fixed a little bug in channel message delivery when channel
5585 private keys are set in the server. Affected file is
5586 silcd/packet_send.c.
5588 * Changed the setting on channel->on_channel = TRUE from the
5589 silc_client_save_channel_key to the JOIN command reply. The
5590 key payload is not received if the private channel key is set.
5591 Affected file lib/silcclient/command_reply.c and the
5592 lib/silcclient/client_channel.c.
5594 * When the CMODE_CHANGE notify is sent and the channel private
5595 key mode is removed the channel key must be re-generated in
5596 other cells as well. Added this support for the router in the
5597 silcd/packet_receive.c.
5599 * Added new local command NOTICE to send notice message on
5600 channel. Affected file silc/local_command.[ch].
5602 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5604 * Added new local command ME to the client. It is used to send
5605 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
5606 some action. Affected file silc/local_command.[ch].
5608 * Changed channel_message and private_message client operations
5609 to deliver the message flags to the application. Added also
5610 the `flags' arguments to the silc_client_send_channel_message
5611 and silc_client_send_private_message functions. Affected file
5614 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5616 * Redefined the Private Message Payload to support private message
5617 keys and to support the new private message flags. Updated
5618 the protocol specs. Flags makes it possible to have for example
5619 CTCP style messages.
5621 * Added new type SilcPrivateMessagePayload and defined an API
5622 for it in the lib/silcclient/silcprivate.[ch].
5624 * Tested private message private keys successfully. Tested the
5625 private message key set, unset and list commands with the new
5628 * Redefined the Channel Message Payload to include the channel
5629 message flags (equal with private message flags) to support
5630 for example CTCP style messages.
5632 * Defined some of the message (for channel and private message)
5633 flags. Updated the protocol specs and added the flags to the
5634 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5636 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5638 * Added SilcKeyAgreementStatus type to the key agreement routines
5639 to indicate the current status and error if one occured.
5640 The status types are defined in the lib/silcclient/silcapi.h.
5642 * Added new local command KEY that is used to set and unset private
5643 keys for channels, set and unset private keys for private messages
5644 with remote clients and to send key agreement requests and
5645 negotiate the key agreement protocol with remote client. The
5646 key agreement is supported only to negotiate private message keys,
5647 it currently cannot be used to negotiate private keys for channels,
5648 as it is not convenient for that purpose.
5650 * Fixed a minor pending callback setting bug in the function
5651 silc_client_get_client_by_id_resolve, now the function works.
5652 Affected file lib/silcclient/idlist.c.
5654 * Added function silc_net_get_local_port to get local bound
5655 port by socket. Added to lib/silcutil/silcnet.[ch].
5657 * Added `sockets' and `sockets_count' fields to the SilcClient
5658 object. They hold the sockets of the listenning sockets in
5659 the client. Listenning sockets may be for example the key
5660 agreement server. Affected file lib/silcclient/client.[ch].
5661 Added functions the silc_client_add_socket and the
5662 silc_client_del_socket. They are exported to the application
5665 * Added ~./silc/clientkeys to support other client's public keys.
5667 * Renamed verify_server_key client operation to verify_public_key
5668 and added one argument to indicate the type of the connection
5669 (server, client etc.).
5671 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5673 * Added silc_server_connection_auth_request to handle the
5674 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5675 silcd/packet_receive.[ch].
5677 * Added silc_server_send_connection_auth_request into the
5678 silcd/packet_send.c to send the connection auth request packet.
5680 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5683 * Fixed the public key authentication in responder side in the
5684 server. The `auth_data' pointer includes the SilcPublicKey
5685 not the path to the public key. Affected file silcd/protocol.c.
5687 * Implemented the public key authentication in the initiator side
5688 in the server. Affected file silcd/protocol.c.
5690 * Removed the [RedirectClient] config section from the server
5691 configuration. Is not needed and I don't want to implement it.
5693 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5695 * Cleaned up the CMODE command in the server. It now works
5696 correctly and supports all the modes defined in the protocol.
5697 Affected file is silcd/command.c.
5699 * Added `hmac_name' field to the SilcChannelEntry in the server
5700 to hold the default HMAC of the channel. It can be set when
5701 creating the channel (with JOIN command). Affected files
5704 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5705 type to indicate the change of the current cipher and hmac
5706 on the channel. Client can safely ignore the <cipher> argument
5707 (if it chooses to do so) since the CHANNEL_KEY packet will
5708 force the channel key change anyway. The <hmac> argument is
5709 important since the client is responsible of setting the new
5710 HMAC and the hmac key into use.
5712 * Fixed the CMODE command in the client library as well.
5714 * Tested CMODE command in router environment successfully.
5716 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5718 * Show the version of the remote client (or server) when connecting
5719 to the server. It is logged to the log file. Affected file
5720 is silcd/protocol.c.
5722 * Fixed the KILLED notify handling in the client library. The
5723 client must be removed from all channels when receiving the
5726 Also, do not remove the client entry when giving the KILL
5727 command but when the KILLED notify is received.
5729 * Removed silc_idlist_find_client_by_nickname from the server.
5730 Not needed anymore. Affected files silcd/idlist.[ch].
5732 * Implemented the CHANNEL_CHANGE notify type handling to the
5733 server. Affected file silcd/server.c.
5737 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5739 * Added silc_server_send_notify_invite to send the INVITE
5740 notify between routers.
5742 * Implemented the INVITE command correctly to the server.
5744 * Implemented the INVITE notify type handling in the server.
5746 * Implemented the INVITE command to the client library and on the
5749 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5751 * Added function silc_server_get_client_resolve to find the
5752 client entry by ID from all ID lists and then resolve it
5753 (using WHOIS) if it cannot be found. Affected file is
5756 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5758 * Implemented the BAN command to the client library.
5760 * The JOIN command in the server now checks the invite list
5763 * Changed the silc_command_reply_payload_encode_va and the
5764 silc_command_payload_encode_va to support that if argument is
5765 NULL it ignores and checks the next argument. Affected file
5766 lib/silccore/silccommand.c.
5768 * Added silc_server_send_notify_ban to send the BAN notify
5769 type between routers.
5771 * Chaned the silc_notify_payload_encode to support that if
5772 argument is NULL it ignores and checks the next argument.
5773 Affected file lib/silccore/silcnotify.c.
5775 * Tested ban lists in router environment successfully.
5777 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5779 * Implemented BAN command to the server, in silcd/command.[ch].
5781 * Removed the BAN and INVITE_LIST modes from the CMODE command
5784 * Added function silc_string_match to regex match two strings.
5785 Affected files lib/silcutil/silcutil.[ch].
5787 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5789 * Redefined parts of the SilcChannelEntry in the server to support
5790 the new ban and invite lists.
5792 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5794 * Redefined the INVITE command. The same command can be used to
5795 invite individuals to the channel but also to manage the invite
5796 list of the channel (to add to and remove from the invite list).
5797 Updated the protocol specs.
5799 * Added new command SILC_COMMAND_BAN that can be used to manage
5800 the ban list of the channel. Updated the protocol specs.
5802 * Removed the channel modes: the SILC_CMODE_BAN and the
5803 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5804 in the CMODE command. The equivalent features are now available
5805 using INVITE and BAN commands. Updated the protocol specs.
5807 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5808 in the network about change in the current ban list. The notify
5809 type is not used by the client.
5811 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5812 support the invite lists.
5814 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5816 * Added new function silc_string_regexify that converts string
5817 including wildcard characters into regex string that can
5818 be used by the GNU regex library. Added into the file
5819 lib/silcutil/silcutil.[ch].
5821 Added silc_string_regex_combine to combine to regex strings
5822 into one so that they can be used as one regex string by
5823 the GNU regex library. Added into the file
5824 lib/silcutil/silcutil.[ch].
5826 Added silc_string_regex_match to match two strings. It returns
5827 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5829 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5831 * Imported GNU regex to the soruce tree into lib/contrib.
5832 Fixed some compiler warning from the regex.c.
5834 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5836 * Fixed MOTD command in the server to work in router environment.
5838 * Fixed the MOTD command in the client library to support
5839 the server argument in the command.
5841 * Added `nickname_len' argument to the silc_idlist_add_client
5842 in the server, as the `nickname' argument may be binary data
5845 * Added silc_idlist_get_channels to return all channels from
5848 * Implemented LIST command to the server. Affected file is
5851 * Implemented the LIST command to the client library and on the
5854 * Added [<user count>] argument to the LIST command reply.
5855 With private channels the user count is not shown.
5857 * Updated TODO and README.
5859 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5861 * The client entry's data.registered must be TRUE even with
5862 global client entry on global client list. The data.registered
5863 is used to check whether the client is anymore in the network,
5864 for example with WHOWAS command so it must be valid.
5866 * Fixed the WHOWAS command in the server. It now actually works
5867 in router environment. Added function into silcd/command_reply.c
5868 silc_server_command_reply_whowas_save.
5870 * Added silc_idlist_purge function to the silcd/idlist.c
5871 to periodically purge the ID Cache.
5873 * Fixed INFO command in the server. It works now in router
5874 environment. Added <server name> argument to the INFO command
5875 reply. Updated the protocol specs.
5877 * Fixed minor bug in silc_idcache_purge to not purge if the
5878 expire value is zero.
5880 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5881 they were buggy because of the WHOWAS information.
5883 * Fixed local command MSG to handle the async resolving of
5884 the remote client properly. It used to fail the first MSG.
5885 Affected file silc/local_command.c.
5887 * Added `data_len' field to SilcIDCache context.
5889 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5891 * Update TODO. Todo in commands in the server.
5893 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5895 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5896 used by routers as broadcast packet to inform other routers
5897 about the changed user mode.
5899 Implemented the notify handling in the server. Affected file is
5900 silcd/packet_receive.c. Added the function
5901 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5903 * Added new generic Channel Payload and deprecated the New Channel
5904 Payload. The New Channel Payload is now the generic Channel
5907 * Added new argument `mode' to the silc_server_send_new_channel
5908 as it is required in the Channel Payload now.
5910 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5911 and created a new and real SilChannelPayload to represent the
5912 new generic Channel Payload. Implemented the encode/decode
5913 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5915 * Added silc_server_get_client_channel_list to return the list
5916 of channels the client has joined for WHOIS command reply.
5917 Affected file silcd/server.[ch].
5919 * Implemented the channel list sending in the WHOIS command reply
5920 in server and in the client.
5922 Implemented the channel list displaying on the user interface
5923 as well. Affected file silc/client_ops.c.
5925 * Added silc_channel_payload_parse_list to parse list of Channel
5926 Payloads. It returns SilcDList list of SilcChannelPayloads.
5927 Client for example can use this function to parse the list of
5928 channels it receives in the WHOIS command reply. The caller
5929 must free the list by calling silc_channel_payload_list_free.
5930 Affected files lib/silccore/silcchannel.[ch].
5932 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5934 * Added one new argument <user mode> to the WHOIS command reply
5935 to return the mode of the user in SILC. Updated the protocol
5938 Implemented it to the server and client.
5940 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5942 * Fixed the mode printing on the user interface on joining.
5943 Affected file silc/client_ops.c.
5945 * Implemented the UMODE command and user modes in general to the
5946 client library and to the user interface.
5948 * Implemented the UMODE command to the server.
5950 * The server now sends UNKNOWN_COMMAND error status if client sends
5951 unknown command. Affected file silcd/command.c.
5953 * All server commands now handle the command identifier the right
5954 way when sending the command reply to the client. The client can
5955 use to identify the command replies with the identifier.
5957 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5959 * Added silc_server_get_client_route to resolve the route to
5960 the client indicated by the client ID. Affected file is
5963 * Added silc_server_relay_packet as general function to relay
5964 packet to arbitrary destination. This deprecates functions
5965 like _send_private_message_key, _relay_notify etc. Affected
5966 file is silcd/packet_send.[ch].
5968 Removed silc_server_send_key_agreement,
5969 silc_server_send_private_message_key and
5970 silc_server_packet_relay_notify functions from the file
5971 silcd/packet_send.[ch].
5975 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5976 server. Affected file silcd/packet_receive.[ch].
5978 * Implemented the KILL command to the client. Implemented the
5979 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5980 Affected files lib/silcclient/command[_reply].c and
5981 lib/silcclient/client_notify.c. Implemented the KILL notify
5982 printing in the user inteface.
5984 * Fixed a lot silc_parse_nick memory leaks from the client
5985 library in the file lib/silcclient/command.c.
5987 * Changed the silc_server_send_notify_on_channels's `sender'
5988 argument from SilcSocketConnection to SilcClientEntry to
5989 check the sender as entry and not as connection object and not
5990 to send to the client provided as argument. The affected file
5991 is silcd/packet_send.[ch].
5993 * The notify packets that are destined directly to the client used
5994 to not to be processed by the server. Now changed that and the
5995 server processes all notify packets. After relaying the packet
5996 to the client the notify packet is processed in the server.
5998 * The silc_server_free_client_data now checks whether there is
5999 pending outgoing traffic for the client and purges the data to
6000 the network before removing the client entry.
6002 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6004 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
6005 an client is killed from the SILC Network. Updated the protocol
6008 Added new function silc_server_send_notify_killed to the
6009 silcd/packet_send.[ch].
6011 * Added function silc_server_packet_relay_notify to relay notify
6012 packets that are destined directly to a client. In this case
6013 the server does not process the notify packets but merely relays
6014 it to the client. Affected file silcd/packet_send.[ch].
6016 Added also silc_server_packet_process_relay_notify to check
6017 whereto relay the notify. Affected file is
6018 silcd/packet_receive.[ch].
6020 * Implemented the KILL command to the server.
6024 * Added the backup schema desgined last fall to the protocol
6025 specs for everyone to see. The specification is in the
6026 *-spec-xx.txt draft and the packet type definitions for the
6027 backup routers is in *-pp-xx.txt draft. Thusly, added also
6028 new packet type SILC_PACKET_CELL_ROUTERS.
6030 * A big security problem in the implementation discovered. The
6031 signoff of an client did not cause new channel key generation
6032 which it of course should've done. The channel keys must be
6033 always re-generated when client leaves (or signoffs) the channel.
6034 The silc_server_remove_from_channels funtion now handles
6035 the channel key re-generation.
6037 * Added `sender' argument to the silc_server_send_notify_on_channels
6038 to not to send the client provided as argument. Affected file
6039 silcd/packet_send.[ch].
6041 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6043 * Implemented OPER and SILCOPER commands into the server and
6046 * Added silc_auth_verify and silc_auth_verify_data to verify
6047 the authentication directly from the authentication payload.
6048 It supports verifying both passphrase and public key based
6049 authentication. Affected file lib/silccore/silcauth.[ch].
6051 * Added `hash' field to the SilcIDListData structure. It is the
6052 hash negotiated in the SKE protocol. Affected file is
6055 * Slight redesigning of the SilcAuthPayload handling routines.
6056 Do not send SilcPKCS but SilcPublicKey as argument.
6058 * Implemented the public key authentication support to the
6059 serverconfig. The public key is loaded from the provided path
6060 and saved as authentication data to void * pointer. Thus,
6061 changed the unsigned char *auth_data to void *auth_data;
6063 * Fixed SHUTDOWN command to send the reply before the server
6064 is shutdown. :) Affected file silcd/command.c.
6066 * Fixed fatal bug in CONNECT command. The hostname was invalid
6067 memory and server crashed. Affected file silcd/command.c.
6069 * Fixed fatal bug in CLOSE command. The server_entry became
6070 invalid but was referenced later in the command. Affected file
6073 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6075 * Fixed fatal bug in failure packet handling. Server ignored
6076 the failure and thus crashed when it came.
6080 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6082 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
6083 that the command may be executed only once in (about) 2 seconds.
6084 The old SILC_CF_LAG flag is same but allows command bursts up
6085 to five before limiting.
6087 Added the support for CF_LAG and CF_LAG_STRICT flags to the
6088 server code. Various commands now includes the CF_LAG_STRICT
6089 flag to disallow any kind of miss-use of the command.
6091 * Fixed the silc_buffer_unformat to not to allocate any data
6092 if the length of the data is zero. It used to allocate the
6093 length + 1. Affected file lib/silcutil/silcbuffmt.c.
6095 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6097 * Changed the format of AdminConnection configuration section
6098 in the server. Added username of the admin to the format.
6099 Affected files silcd/serverconfig.[ch].
6101 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
6102 to return admin configuration data by host, username and/or
6105 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6107 * Implemented WHOWAS command to the server. Added the functions:
6109 silc_server_command_whowas_parse,
6110 silc_server_command_whowas_send_reply,
6111 silc_server_command_whowas_from_client and
6112 silc_server_command_whowas_from_server
6114 * Added <Client ID> argument to the WHOWAS command reply. Updated
6115 the protocol specs accordingly.
6117 * Implemented WHOWAS command and command_reply to the client
6120 Implemented the WHOWAS printing on the user interface.
6122 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6124 * Added new argument to the WHOWAS command reply, the real name.
6125 It is an optional argument. Updated the protocol specs.
6127 * Added SilcIDCacheDestructor callback that is registered when
6128 the SilcIDCache is allocated. The callback is called when
6129 an cache entry in the ID Cache expires, or is purged from the
6130 cache. Added into lib/silccore/idcache.[ch].
6132 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
6133 to destruct the client entries when the cache entry expires.
6134 Other ID Cache's in server and in the client library ignores
6137 * If the ID Cache entry's `expire' field is zero then the entry
6138 never expires. Added boolean `expire' argument to the
6139 silc_idcache_add function in the lib/silccore/idcache.[ch].
6140 If it is TRUE the default expiry value is used.
6142 * Added silc_server_free_client_data_timeout that is registered
6143 when client disconnects. By default for 5 minutes we preserve
6144 the client entry for history - for WHOWAS command.
6146 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6148 * Added support to the server to enforce that commands are not
6149 executed more than once in 2 seconds. If server receives
6150 commands from client more frequently, timeout is registered
6151 to process the commands. Affected file silcd/command.c.
6152 Added new function silc_server_command_process_timeout.
6154 * Changed NICK_NOTIFY handling in client library to check that
6155 if the client's nickname was changed, so there is no need to
6156 resolve anything from the server.
6158 * Removed error printing from the WHOIS and IDENTIFY commands.
6159 If error occurs then it is ignored silently in the client library.
6160 The application, however, may map the received error to
6161 human readable error string. The application currently maps
6162 the NO_SUCH_NICKNAME error to string.
6164 * Made the command status message public to the application. Moved
6165 them from lib/silcclient/command_reply.c to
6166 lib/silcclient/command_reply.h. The application can map the
6167 received command status to the string with the
6168 silc_client_command_status_message function.
6170 * Added check to the server to check that client's ID is same
6171 as the Source ID in the packet the client sent. They must
6174 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6176 * Added dist-bzip hook to the Makefile.am to make bzip2
6177 compressed distributions.
6179 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6181 * Server now enforces the maximum length for the nickname and
6182 the channel as protocol specification dictates. 128 bytes for
6183 nickname and 256 bytes for channel name.
6185 * Moved the WHOIS printing to the application. The client libary
6186 does not print out the WHOIS information anymore, the application
6187 must do it. Renamed silc_client_command_reply_whois_print to
6188 the silc_client_command_reply_whois_save.
6190 The client's idle time is also sent to the application now, and
6191 the idle is shown on screen.
6193 * Added silc_client_command_reply_identify_save to save the
6194 received IDENTIFY entries.
6196 * Do not check for channel private keys in message sending and
6197 reception if the channel does not have the PRIVKEY mode set.
6198 Affected file lib/silclient/client_channel.c.
6200 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6202 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
6203 just surfaced after chaning the JOIN procedure.
6205 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6207 * Added silc_client_get_clients_by_list to get client entries
6208 from Client ID list, that is returned for example by JOIN
6209 and USERS command replies. The application should use this
6210 function for example when JOIN command reply is received to
6211 resolve the clients already on the channel (library does not
6212 do that anymore as USERS command reply is not used in the JOIN
6213 procedure anymore). Affected files lib/silcclient/silcapi.h and
6214 lib/silcclient/idlist.c.
6216 * JOIN command reply and USERS command reply returns now SilcBuffer
6217 pointers instead of unsigned char pointers when returning
6218 the client list and mode list.
6220 * Added <Client ID> argument to the JOIN command reply, mainly
6221 for the server to identify for which client the command was
6222 originally sent. Updated protocol specs accordingly.
6224 * Added SilcDlist private_key pointer to the SilcChannelEntry
6225 in the client to support the channel private keys. Affected
6226 file is lib/silcclient/idlist.h.
6228 * Added SilcChannelPrivateKey argument to the function
6229 silc_client_send_channel_message so that application can choose
6230 to use specific private ke if it wants to. If it is not provided,
6231 the normal channel key is used, unless private keys are set.
6232 In this case the first (key that was added first) is used
6233 as the encryption key.
6235 * Implemented the support for channel private key handling.
6236 Implemented the following functions:
6238 silc_client_add_channel_private_key,
6239 silc_client_del_channel_private_keys,
6240 silc_client_del_channel_private_key,
6241 silc_client_list_channel_private_keys and
6242 silc_client_free_channel_private_keys
6244 Affected file lib/silcclient/client_channel.c.
6246 * Added the support for the private keys in the channel message
6247 sending and encryption and in the message reception and
6248 decryption. Affected funtions are
6249 silc_client_send_channel_message and silc_client_channel_message.
6251 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6253 * Added SKE's key verify callback to the client library's
6254 KE protocol context. Affected files lib/silcclient/protocol.[ch].
6256 * Removed the statement that server (or router) must send USERS
6257 command reply when joining to the channel so that the client
6258 knows who are on the channel. Instead, the client list and
6259 client's mode list is now sent in the JOIN command reply to the
6260 client who joined channel. This is better solution.
6262 * Added function silc_server_get_users_on_channel and function
6263 silc_server_save_users_on_channel to the silcd/server.[ch].
6265 * Removed function silc_server_command_send_users from the
6268 * Do not show topic on the client library anymore. The topic is
6269 sent in the command reply notify to the application and the
6270 application must show the topic now.
6272 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6274 * Added client searching by nickname hash into the IDENTIFY and
6275 WHOIS commands in the server as they were clearly missing from
6276 them. Affected file is silcd/command.c.
6278 * Fixed a bug in private message receiving in the client library.
6279 The remote ID was freed and it wasn't supposed, now it is
6282 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6284 * Minor fix to the channel payload; allocate the data area, as it
6285 needs to be of specific length.
6287 * If the key agreement port is zero then the operating
6288 system will define the bound port. Affected files are
6289 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
6291 * Added new function silc_channel_payload_decrypt into the file
6292 lib/silccore/silcchannel.[ch].
6294 * Moved the channel message etc, check from silc_packet_decrypt
6295 to applications. The library calls now a generic
6296 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
6297 when the packet is either normal or special. This was done to
6298 allow more wide range of checking that was not allowed when
6299 the code was in library. Now applications can do virtually any
6300 checks to the packet and return to the library the decision how
6301 the packet should be processed. Affected files are
6302 lib/silccore/silcpacket.[ch].
6304 Added silc_server_packet_decrypt_check to the server and
6305 silc_client_packet_decrypt_check to the client library.
6307 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
6308 to send with specified source and destination information.
6310 * Channel message delivery between routers was broken after the
6311 channel key distribution was fixed earlier. The channel key
6312 was used be to distributed to other routers as well which is not
6313 allowed by the protocol. Now this is fixed and channel keys
6314 really are cell specific and the channel message delivery between
6315 routers comply with the protocol specification.
6317 * Fixed various commands in server to check also the global list
6318 for the channel entry and not just the local list. The affected
6319 file silcd/command.c.
6321 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6323 * Added assert()s to buffer formatting and unformatting routines
6324 to assert (if --enable-debug) when error occurs. Affected
6325 file: lib/silcutil/silcbuffmt.c.
6327 * Changed to auto-reconnect to check whether the remote host is
6328 router and register the re-connect timeout if it is. It used
6329 to check that whether we are normal server, but router must do
6330 auto-reconnect with another router as well. Affected file
6333 * Removed the [<key len>] option from CMODE command as the cipher
6334 name decides the key length, nowadays. See the defined ciphers
6335 from the protocol specification.
6337 * Added [<hmac>] option to the CMODE command to define the HMAC
6338 for the channel. Added SILC_CMODE_HMAC channel mode.
6340 * Added [<hmac>] option for the JOIN command so that user can
6341 select which HMAC is used to compute the MACs of the channel
6344 * Added Hmac field to the Channel Message Payload. The integrity
6345 of plaintext channel messages are now protected by computing
6346 MAC of the message and attaching the MAC to the payload. The
6347 MAC is encrypted. Now, it is clear that this causes some
6348 overhead to the size of the packet but rationale for this is that
6349 now the receiver can verify whether the channel message decrypted
6350 correctly and also when private keys are set for the channel the
6351 receiver can decrypt the packet with several keys and check from
6352 the MAC which key decrypted the message correctly.
6354 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
6355 lib/silccrypt/silccipher.[ch].
6357 * Added silc_hash_len to return the digest length into the
6358 lib/silcrypt/silchash.[ch].
6360 * Rewrote parts of Silc Channel Payload interface in the
6361 lib/silccore/silcchannel.[ch]. The encode function now also
6362 encrypts the packet and parse function decrypts it.
6364 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6366 * Fixed a minor formatting bug in the SKE's key material processing.
6367 It actually might have processed the keys wrong way resulting
6370 * Redefined the mandatory HMAC algorithms and added new algorithms.
6371 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
6372 and hmac-md5 truncated to 96 bits. The mandatory is now
6373 hmac-sha1-96. Rest are optional (including the one that used
6374 to be mandatory). Rationale for this is that the truncated HMAC
6375 length is sufficient from security point of view and can actually
6376 make the attack against the HMAC harder. Also, the truncated
6377 HMAC causes less overhead to the packets. See the RFC2104 for
6380 * Added new [hmac] configuration section. The SKE used to use
6381 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
6382 is of course wrong. The official names that must be proposed in
6383 the SKE are the ones defined in the protocol specification
6384 (hmac-sha1-96 for example). The user can configure any hmac
6385 using any hash function configured in the [hash] section. At
6386 least, the mandatory must be configured.
6388 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
6390 * Added HMAC list to the SKE proposal list. It has now both
6391 hash algorithm list and HMAC list. This makes the protocol
6392 incompatible with previous versions. The SKE now seems to work
6393 the way it is supposed to work, for the first time actually.
6395 * Defined plain Hash algorithms to the protocol specification.
6398 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6400 * Implemented support for key agreement packets into the server.
6401 Added functions silc_server_key_agreement and
6402 silc_server_send_key_agreement. Other than these functions,
6403 server has nothing to do with this packet.
6405 * Added support for private message key packets into the server.
6406 Added functions silc_server_private_message_key and
6407 silc_server_send_private_message_key.
6411 * Changed the silc_[client|server]_protocol_ke_set_keys to be
6412 called in the protocol's final callback instead in the END
6413 protocol state. This makes a little more sense and in the same
6414 time in client we can use the same protocol routines for normal
6415 key exchange and to key agreement packet handling as well.
6417 * Added to both client's and server's KE protocol context the
6418 SilcSKEKeyMaterial pointer to save the key material. We will
6419 bring the key material to the protocol's final callback by doing
6420 this. The final callback must free the key material.
6422 * Added SKE's packet_send callback into client's KE protocol
6423 context so that the caller can choose what packet sending function
6424 is used. This way we can use different packet sending when
6425 doing normal SKE when doing key agreement packet handling (in
6426 the key agreement packet handling we do not want to encrypt
6429 * Implemented the responder side of the key agreement routines
6430 in the client. The client can now bind to specified port and
6431 accept incoming key negotiation. The key material is passed
6432 to the application after the protocol is over.
6434 * Implemented the processing of incoming Key Agreement packet
6435 in the client. Added function silc_client_key_agreement to
6438 * Implemented the intiator side of the key agreement routines
6439 in the client. The client can now initiate key agreement with
6440 another remote client. The key material is passed to the
6441 application after the protocol is over.
6443 * Created client_keyagr.c to include all the key agreement
6446 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
6447 SILC_TASK_CALLBACK except that it is not static.
6449 * Created client_notify.c and moved the Notify packet handling
6450 from the client.[ch] into that file.
6452 * Created client_prvmsg.c and moved all private message and
6453 private message key routines from the client.[ch] into that file.
6455 * Create client_channel.c and moved all channel message and
6456 channel private key routines from the client.[ch] into that file.
6458 * Changed silc_client_get_client_by_id_resolve to resolve with
6459 WHOIS command instead of IDENTIFY command, in the file
6460 lib/silclient/idlist.c.
6462 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6464 * Implemented the SKE's responder side to the Client library.
6466 * When FAILURE is received to the protocol do not trust it
6467 blindly. Register a timeout to wait whether the remote closes
6468 the connection as it should do it, only after that process the
6469 actual failure. This was changed to both client and server.
6471 * Added client_internal.h to include some of the structures
6472 there instead of client.h in lib/silcclient/.
6474 * Added function silc_task_unregister_by_callback to unregister
6475 timeouts by the callback function.
6477 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6479 * Some "Incomplete WHOIS info" errors has been appearing on the
6480 log files. Took away the entry->userinfo check from WHOIS
6481 reply sending. The entry->userinfo is now " " if client did not
6482 provide one. I thought this was fixed earlier but something
6483 is wrong still. Let's see if the error still appears.
6485 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6487 * Fixed a minor bug in the login when the channel key is
6488 re-generated in the server. It used to generate the key in
6489 wrong order and thus caused problems in the channel traffic.
6491 * Fixed a minor bug in channel key distsribution after
6492 KICK command. The key was not sent to the router even though
6495 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6497 * Added silc_ske_process_key_material_data as generic routine
6498 to process any key material as the SILC protocol dictates. The
6499 function is used by the actual SKE library but can be used by
6500 applications as well. This relates to the private message keys
6501 and the channel private keys since they must be processed the
6502 same way the normal SILC session keys. The protocol dictates
6503 this. Affected files: lib/silcske/silcske.[ch].
6505 Added also silc_ske_free_key_material to free the
6506 SilcSKEKeyMaterial structure.
6508 * Defined silc_cipher_set_key function to set the key for
6509 cipher without using the object's method function. The affected
6510 files: lib/silccrypt/silccipher.[ch].
6512 * Implemented silc silc_client_add_private_message_key,
6513 silc_client_add_private_message_key_ske,
6514 silc_client_del_private_message_key,
6515 silc_client_list_private_message_keys and
6516 silc_client_free_private_message_keys functions in the
6519 Added functions silc_client_send_private_message_key to send
6520 the Private Message Key payload and silc_client_private_message_key
6521 to handle incoming Private Message Key payload.
6523 * Added Cipher field to the Private Message Key payload to set
6524 the cipher to be used. If ignored, the default cipher defined
6525 in the SILC protocol (aes-256-cbc) is used.
6527 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6529 * Removed lib/silcclient/ops.h file.
6531 Redefined parts of the SILC Client Library API. Created new
6532 file silcapi.h that deprecates the ops.h file and defines the
6533 published Client Library API. Defined also private message key
6534 API and channel private key API into the file.
6536 This is the file that the application must include from the
6537 SILC Client Library. Other files need not be included by
6538 the application anymore.
6540 * Added new key_agreement client operation callback and also
6541 defined the Key Agreement library API for the application.
6543 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6545 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
6546 is used by clients to request key negotiation between another
6547 client in the SILC network. If the negotiation is started it
6548 is performed using the SKE protocol. The result of the
6549 negotiation, the secret key material, can be used for example
6550 as private message key.
6552 Implemented the Key Agreement payload into the files
6553 lib/silccore/silauth.[ch].
6555 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6557 * Redefined ciphers for the SILC protocol. Added some new ciphers
6558 and defined the key lengths for the algorithms. Changed the
6559 code accordingly. The default key length is now 256 bits.
6561 * Fixed SKE key distribution function silc_ske_process_key_material
6562 when the key length is more than 128 bits. The default key
6563 length in SILC is now 256 bits.
6565 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
6566 to indicate unsupported algorithm.
6568 * Renamed rijndael.c to aes.c and all functions as well.
6570 * Fixed a long standing channel key setting bug in client library.
6571 Weird that it has never surfaced before.
6573 * Fixed bug in channel deletion. If the entire channel is removed
6574 then it must also delete the references of the channel entry
6575 from the client's channel list as the client's channel entry and
6576 the channel's client entry share same memory.
6578 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6580 * Implemented CONNECT and SHUTDOWN commands in the client.
6582 * Implemented CLOSE command to the client.
6584 * Added the function silc_idlist_find_server_by_name into the
6585 files silcd/idlist.[ch].
6587 Added the function silc_idlist_find_server_by_conn into the
6588 files silcd/idlist.[ch].
6590 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6592 * DIE command was renamed to SHUTDOWN. Updated the both code
6595 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
6596 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
6598 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
6601 * Added function silc_server_create_connection function to create
6602 connection to remote router. My server implementation actually
6603 does not allow router to connect to normal server (it expects
6604 that normal server always initiates the connection to the router)
6605 so the CONNECT command is only good for connecting to another
6608 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6610 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
6611 or some other client was kicked from the channel.
6613 Implemented the handling of the notify type to both client
6616 Implemented silc_server_send_notify_kicked to send the KICKED
6617 notify. It is used to send it to the server's primary router.
6619 * Implemented the KICK command into server and client.
6621 * Added `query' argument to the silc_idlist_get_client function
6622 to indicate whether to query the client from server or not if
6625 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
6626 to indicate that the client is not channel founder.
6630 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6632 * Removed the rng context from SilcPacketContext structure and
6633 changed that the packet routine uses the Global RNG API.
6635 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6637 * Added support for quit message that client can "leave" on the
6638 channel when it quits the SILC. It is ditributed inside the
6639 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6641 Added silc_server_free_client_data that will take the
6642 signoff message as argument.
6644 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6646 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6648 * Updated parts of the protocol specification to keep it up
6651 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6653 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6654 payloads in one packet.
6656 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6657 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6658 use now the new List flag.
6660 * Also deprecated the following packet types: REPLACE_ID,
6661 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6663 * Added list support for Notify packet in server.
6665 * Added silc_server_send_notify_channel_change to send the
6666 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6667 the silc_server_send_replace_id.
6669 * Added silc_server_send_notify_nick_change to send the
6670 NICK_CHANGE notify type. Deprecates the function
6671 silc_server_send_replace_id.
6673 * Added silc_server_send_notify_join to send the JOIN notify type.
6674 Deprecates the function silc_server_send_new_channel_user.
6676 * Added silc_server_send_notify_leave to send LEAVE notify type.
6677 Deprecates the function silc_server_send_remove_channel_user.
6679 * Added silc_server_send_notify_cmode and
6680 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6681 types. Deprecates the silc_server_send_set_mode function.
6683 * Added SERVER_SIGNOFF notify type to indicate that server has
6684 quit. This means that all clients on the channel from that
6685 server will drop. This can be also used when netsplit happens.
6687 Deprecated REMOVE_ID packet type since it is not needed anymore
6690 Added silc_server_send_notify_server_signoff to send the
6691 SERVER_SIGNOFF notify type. Deprecates the function
6692 silc_server_send_remove_id.
6694 Added also silc_server_send_notify_signoff to send the
6695 SIGNOFF notify type.
6697 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6698 SILC protocol from this day on. Changed the protocol
6699 specification as well.
6701 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6702 notify type. It is used between routers to notify about
6703 topic changes on a channel.
6705 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6708 * Partly updated the protocol specification to comply with the
6709 changes now made. It is still though a bit outdated.
6711 * The JOIN notify type now takes one extra argument <Channel ID>.
6712 The packet used to be destined to the channel but now the
6713 JOIN type may be sent as list thus it is impossible to
6714 destine it to any specific channel. By adding this argument
6715 it is again possible.
6717 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6719 * Added CREDITS file. The CHANGES and CREDITS file will appear
6720 in the distribution as well.
6722 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6724 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6725 types in the server's silcd/packet_receive.c.
6727 * Implemented CMODE and CUMODE to work in router environment.
6729 * Fixed minor encoding and decoding buglet from the
6730 lib/silccore/silcmode.c.
6732 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6735 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6737 * Changed all SilcConfigServer* and silc_config_server* to
6738 SilcServerConfig* and silc_server_config*, respectively.
6741 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6743 * Associated the ID (client or server ID) to the Authentication
6744 Payload to avoid any possibility of forging. Updated the
6745 protocol specification and the code accordingly.
6747 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6749 * The RSA key length is now save to the RsaKey context in the
6750 key generation process in lib/silccrypt/rsa.c. The key length
6751 is now used to figure out the maximum size of the block allowed
6752 to be encrypted/signed.
6754 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6755 is equivalent to the silc_mp_mp2bin but does not allocate any
6758 * Changed silc_mp_mp2bin API to take length argument. If it is
6759 non-zero then the buffer is allocated that large. If zero, then
6760 the size is approximated using silc_mp_sizeinbase, which however
6763 * Created Global RNG API which is global RNG that application can
6764 initialize. After initializing, any routine anywhere in the
6765 code (including library) can use RNG without allocating a new
6766 RNG object. This was done to allow this sort of use of the
6767 RNG in code that has no chance to allocate RNG object. All
6768 applications currently allocate this and many routines in the
6769 library use this. Affected file lib/silccrypt/silcrng.[ch].
6771 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6772 it to use the Global RNG API.
6774 * Defined Authentication Payload into protocol specification that
6775 is used during SILC session to authenticate entities. It is
6776 used for example by client to authenticate itself to the server
6777 to obtain server operator privileges.
6779 Implemented this payload into the lib/silccore/silcauth.[ch].
6780 Implemented also routines for public key based authentication
6781 as the new protocol specification dictates.
6783 Moved definitions of different authentication methods from
6784 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6786 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6787 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6788 silc_pkcs_verify_with_hash functions into the file
6789 lib/silccrypt/silcpkcs.[ch].
6791 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6793 * The client entry's userinfo pointer must be always valid.
6794 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6795 will fail since it requires the userinfo. Now, the userinfo
6796 is allocated as "" if actual userinfo does not exist. Actually,
6797 it must exist and it is totally Ok to drop client connections
6798 that does not announce the userinfo. However, we will make
6799 this workaround for now.
6801 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6802 to return the remote port by socket.
6804 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6806 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6807 SILC_SERVER_PENDING_EXEC and added an new macro
6808 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6809 data or when error occurs while processing the pending command.
6811 Added new argument `destructor' into silc_server_command_pending
6812 and to the SilcServerCommandPending object. This destructor is
6813 now called after calling the pending callback or if error occurs
6814 immediately. If error occurs the actual pending callback won't
6815 be called at all - only the destructor. The destructor may be
6816 NULL if destructor is not needed.
6818 All this applies for client library code as well. Similar
6819 changes were made there as well for the pending commands.
6821 In the client, the application must now allocate the
6822 SilcClientCommandContext with the silc_client_command_alloc
6825 * Added reference counter to the SilcServerCommandContext. Added
6826 function silc_server_command_alloc and silc_server_command_dup
6829 Same type of functions added to the client library for the same
6832 * Removed the cmd_ident from IDListData away since it is now
6833 global for all connections. It is the command identifier used
6834 in command sending and with pending commands. The affected file
6837 * Added reference counter to the SilcSocketConnection objecet to
6838 indicate the usage count of the object. The object won't be
6839 freed untill the reference counter hits zero. Currently only
6840 server uses this, and client ignores it. The client must be
6841 set to use this too later. The affected files are
6842 lib/silccore/silcsockconn.[ch]. Added also the function
6843 silc_socket_dup to increase the reference counter.
6845 This was mainly added because it is possible that the socket
6846 is removed underneath of pending command or other async
6847 operation. Now it won't be free'd and proper DISCONNECTING
6848 flags, etc. can be set to avoid sending data to connection that
6849 is not valid anymore.
6851 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6852 the connection. After that it sets SILC_SET_DISCONNECTED.
6853 It is, however, possible that the socket data is not still freed.
6854 The silc_server_packet_process now checks that data is not
6855 read or written to connection that is DISCONNECTED. The socket
6856 get's freed when the reference counter hits zero.
6858 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6860 * Changed the client operation API: channel_message operation's
6861 `sender' is now the client entry of the sender, not the nickname
6862 and the `channel' is the channel entry, not the channel name.
6864 In the private_message operation the `sender' is now also the
6865 client entry of the sender not the nickname.
6867 Affected file is lib/silcclient/ops.h and all applications
6868 using the client operations.
6870 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6872 * Moved the calling of ops->connect() from connect_to_server_final
6873 into receive_new_id functin since that is the point when the
6874 client is actually allowed to send traffic to network. The
6875 affected file is lib/silcclient/client.c.
6877 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6879 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6880 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6881 (if needs broadcasting) instead of broadcasting the packets one
6882 by one which would make a burst in the network traffic.
6884 * Added `broadcast' argument to the functions in silcd/server.[ch]
6885 silc_server_create_new_channel[_with_id] to indicate whether
6886 to send New Channel packet to primary router.
6888 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6890 * Added new function into the silcd/server.[ch] files:
6891 silc_server_create_new_channel_with_id to create new channel with
6892 already existing Channel ID.
6894 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6895 lib/silccore/silcpacket.h. This packet is used t send list of
6896 Set Mode payloads inside one packet. Server uses this to set
6897 the modes for the channels and clients on those channels, that it
6898 announced to the router when it connected to it. The protocol
6899 specification has been updated accordingly.
6901 * The silc_server_new_channel did not handle the packet coming
6902 from normal server as it normally does not send that. However,
6903 when it announces its channels it does send it. Implemented
6904 the support for that.
6906 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6907 into the file lib/silccore/id.h.
6909 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6911 * Fixed memory leaks in the functions silc_idlist_del_client,
6912 silc_idlist_del_channel and silc_idlist_del_server in the file
6913 silcd/idlist.c. All of those leaked like a sieve.
6915 * Fixed some small memory leaks in the client's function
6916 silc_client_notify_by_server.
6918 * Added functions into silcd/server.c: silc_server_announce_clients,
6919 silc_server_announce_channels and silc_server_announce_server.
6920 These functions are used by normal and router server to announce
6921 to its primary router about clients, channels and servers (when
6922 router) that we own. This is done after we've connected to the
6925 These functions effectively implements the following packet types:
6926 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6927 and SILC_PACKET_NEW_ID_LIST.
6929 * Added new functions into the silcd/packet_receive.[ch]:
6930 silc_server_new_id_list, silc_server_new_channel_list and
6931 silc_server_new_channel_user_list to handle the incoming
6932 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6934 * Added support of changing Channel ID in the function
6935 silc_server_replace_id. If the server that announces a channel
6936 to the router already exists in the router (with same name but
6937 with different Channel ID), router is responsible to send
6938 Replace ID packet to the server and force the server to change
6939 the Channel ID to the one router has.
6941 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6942 client that the Channel ID has been changed by the router. The
6943 normal server sends this to the client. Client must start using
6944 the new Channel ID as the channel's ID.
6946 Implemented handling of this new type into lib/silcclient/client.c
6947 into the function silc_client_notify_by_server.
6949 * Added new function silc_idlist_replace_channel_id into the files
6950 silcd/idlist.[ch] to replace the Channel ID.
6952 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6954 * Call silc_server_command_identify_check always when processing
6955 the IDENTIFY command in silcd/command.c
6957 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6959 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6960 send keepalive packets. The packet can be sent by clients,
6961 servers and routers.
6963 Added function silc_socket_set_heartbeat into the file
6964 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6965 If not set, the heartbeat is not performed. The actual
6966 heartbeat is implemented in the low level socket connection
6967 library. However, application is responsible of actually
6970 Added silc_server_send_heartbeat to send the actual heartbeat
6971 packet into silcd/packet_send.[ch]. Server now performs
6972 keepalive with all connections.
6974 * Added silc_task_get_first function into lib/silcutil/silctask.c
6975 to return the timeout task with shortest timeout. There was a bug
6976 in task unregistration that caused problems. TODO has been
6977 updated to include that task system must be rewritten.
6979 * The client library will now resolve the client information when
6980 receiving JOIN notify from server for client that we know but
6981 have incomplete information.
6983 * Rewrote parts of silc_server_remove_from_channels and
6984 silc_server_remove_from_one_channel as they did not remove the
6985 channel in some circumstances even though they should've.
6987 * Encryption problem encountered in server:
6989 The LEAVE command used to send the Channel Key packet to the
6990 router immediately after generating it. However, the code
6991 had earlier sent Remove Channel user packet but not immediately,
6992 ie. it was put to queue. The order of packets in the router
6993 was that Channel Key packet was first and Remove Channel User
6994 packet was second, even though they were encrypted in the
6995 reverse order. For this reason, MAC check failed. Now, this
6996 is fixed by not sending the Channel Key packet immediately but
6997 putting it to queue. However, this is more fundamental problem:
6998 packets that are in queue should actually not be encrypted
6999 because packets that are sent immediately gets encrypted
7000 actually with wrong IV (and thus MAC check fails). So, packets
7001 that are in queue should be encrypted when they are sent to
7002 the wire and not when they put to the queue.
7004 However, the problem is that the current system has not been
7005 designed to work that way. Instead, the packet is encrypted
7006 as soon as possible and left to the queue. The queue is then
7007 just purged into wire. There won't be any fixes for this
7008 any time soon. So, the current semantic for packet sending
7011 o If you send packet to remote host and do not force the send
7012 (the packet will be in queue) then all subsequent packets to the
7013 same remote host must also be put to the queue. Only after the
7014 queue has been purged is it safe again to force the packet
7017 o If you send all packets immediately then it safe to send
7018 any of subsequent packets through the queue, however, after
7019 the first packet is put to queue then any subsequent packets
7020 must also be put to the queue.
7022 Follow these rules and everything works fine.
7024 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7026 * Added new function silc_server_remove_clients_by_server to
7027 remove all client entries from ID list when the server connection
7028 is lost. In this case it is also important to invalidate all
7029 client entires as they hold the invalid server entry. This
7030 fixes fatal bug when server has lost connection and will reconnect
7033 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7035 * Made some sanity checks to silc_server_daemonise like to check
7036 whether the requested user and group actually exists.
7038 * Added sanity check to SKE's silc_ske_responder_finish to check
7039 that the public and private key actually is valid.
7041 * Invalidate the client's nickname when receiving Replace ID
7042 packet and the Client ID is being replaced. This means that the
7043 server will query the nickname if someone needs it (client)
7046 * Sort the ID Cache in client library when the ID Cache data
7047 has changed (needs sorting).
7049 * Do not allow for SILC client to create several connections to
7050 several servers. The client does not support windows right now
7051 and generating multiple connections causes weird behaviour.
7053 Irssi-silc client does support windows and can handle several
7054 connections without problems, see: www.irssi.org and SILC plugin.
7056 * Fixed some places where client was added to the IDList. The
7057 rule of thumb is following (in order to get everything right):
7058 If the client is directly connected local client then the
7059 `connection' argument must be set and `router' argument must be
7060 NULL to silc_idlist_add_client function. If the client is not
7061 directly connected client then the `router' argument must
7062 bet set and the `connection' argument must be NULL to the
7063 silc_idlist_add_client function.
7065 * The funtion silc_server_packet_send_local_channel actually did
7066 not check whether the client was locally connected or not. It
7067 does that now. Fixed a bug related to LEAVE command.
7069 * Fixed Remove Channel User payload parsing bug in server's
7070 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
7072 * The server's silc_server_save_channel_key now checks also the
7073 global ID list for the channel as it might not be in the local
7074 list. Fixed a bug related to LEAVE command.
7076 * Is this the end of the [<unknown>] buglet that has been lurking
7077 around for a long time? A little for loop fix in server's
7078 silc_server_command_whois_parse that is used by both IDENTIFY
7079 and WHOIS command. At least, this was a clear bug and a cause
7080 of one type of [<unknown>] buglet.
7082 * WHOIS and IDENTIFY commands call the function
7083 silc_server_command_[whois/identify]_check function even if
7084 we are not router server.
7086 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7088 * Added --with-gmp configuration option. If set the GMP
7089 is always compiled in the SILC source tree. If not set then
7090 it is checked whether the system has the GMP3 installed. If
7091 it has then the GMP won't be compiled (the system's headers
7092 and library is used), if it doesn't have it then the GMP is
7093 compiled in the SILC source tree.
7095 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7097 * Changed RSA private exponent generation to what PKCS #1
7098 suggests. We try to find the smallest possible d by doing
7099 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
7100 not security fix but optimization.
7102 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7104 * Added new config entry [Identity] to fork the server and run
7105 it as specific user and group. A patch from Bostik.
7107 * Imported Dotconf configuration library into lib/dotconf.
7108 This will be used to create the SILC configuration files later.
7109 It will appear in the distsribution after this commit.
7111 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7113 * A big code auditing weekend happening. Auditing code for
7114 obvious mistakes, bugs and errors. Also, removing any code
7117 Removed files for being obsolete:
7119 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
7120 inline in the file lib/silcutil/silcbuffer.h)
7122 o lib/silcutil/silcbufutil.c (the header has inline versions)
7124 Changed code to fix possible error conditions:
7126 o The buffer formatting routines now check that the destination
7127 buffer really has enough space to add the data. This applies for
7128 both buffer formatting and unformatting
7129 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
7130 unformatting was changed to accomodate following rules:
7131 XXX_*STRING_ALLOC will allocate space for the data into the pointer
7132 sent to the function while XXX_*STRING will not allocate or copy
7133 the data into the buffer. Instead it sets the pointer from the
7134 buffer into the pointer sent as argument (XXX_*STRING used to
7135 require that the pointer must be allocated already). This change
7136 makes this whole thing a bit more consistent and more optimized
7137 (note that the data returned in the unformatting with XXX_*STRING
7138 must not be freed now). The routines return now -1 on error.
7140 o Tried to find all code that use buffer_format and buffer_unformat
7141 and added return value checking to prevent formatting and
7142 especially unformatting errors and possible subsequent fatal
7145 o Changed ske->x and ske->KEY to mallocated pointers in
7146 lib/silcske/silcske.h. Fixed possible data and memory leak.
7148 o Added return value checking to all *_parse* functions. Fixed
7149 many memory leaks as well.
7151 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
7152 so that buffer overflows would not happen. All code now also
7153 checks the return value as it can fail.
7155 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7157 * Added reconnection support to server if the normal server looses
7158 its connection to the router (for example if router is rebooted).
7159 The server performs normal reconnection strategy implemented
7160 to the server. Affected file silcd/server.c.
7162 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7164 * Added new packet type SILC_PACKET_SET_MODE that is used to
7165 distribute the information about changed modes (for clients,
7166 channels and clients channel modes) to all routers in the
7167 network. Updated the protocol specification accordingly.
7169 Added functions into silcd/packet_send.c and
7170 silcd/packet_receive.c: silc_server_send_set_mode,
7171 silc_server_set_mode.
7173 Added new files silcmode.[ch] into lib/silccore that implements
7174 the encoding and decoding of Set Mode Payload. Added new type
7175 SilcSetModePayload. Moved the definitions of different modes
7176 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
7178 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7180 * Oops, a little mistake in server's connection authentication
7181 protocol. The protocol is not ended with FAILURE but with
7182 SUCCESS if the authentication is Ok. :) Affected file is
7185 * Implemented NICK_CHANGE notify handling in server in the file
7186 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
7187 the local clients on the channel. After the changing nickname
7188 in router environment snhould work and the [<unknown>] nickname
7189 should appear no more.
7191 The silc_server_replace_id function that receives the Replace ID
7192 payload now sends the NICK_CHANGE notify type also in the file
7193 silcd/packet_receive.c
7195 * Changed WHOIS and IDENTIFY command to support the maximum amount
7196 of arguments defined in protocol specs (3328 arguments). This
7197 fixed a bug that caused problems when there were more than three
7200 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7202 * Added extra parameter, command identifier, to the
7203 silc_client_send_command so that explicit command identifier
7206 Changed that ID list routines uses specific command identifier
7207 when sending WHOIS/IDENTIFY requests to the server so that they
7208 can be identified when the reply comes back.
7210 Affected files lib/silcclient/command.[ch],
7211 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
7213 * Added `sender' argument to silc_server_packet_send_to_channel
7214 to indicaet the sender who originally sent the packet to us
7215 that we are now re-sending. Ignored if NULL. Affected file
7216 silcd/packet_send.[ch].
7218 * Added some server statistics support in silcd/server_internal.h
7219 SilcServerStatistics structure and around the server code. Also
7220 send some nice statistics information when client is connecting
7223 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7225 * Fixed channel ID decoding in server's JOIN command reply in
7226 silcd/command_reply.c
7228 * Fixed braodcasting of replace ID payload to not to send it if
7229 we are standalone server in silcd/packet_receive.c.
7231 * Fixed all channel message sending routines to not to send
7232 packets to clients that has router set, since they are routed
7233 separately in the same function earlier. Affects file
7234 silcd/packet_send.c and all channel packet sending functions.
7236 * In USERS reply, res_argv[i] are not allocated, the table
7237 is allocated. Thus changed that free the table, not its
7240 * In server's whois_check and identify_check if the client is
7241 locally connected do not send any WHOIS commands - they are not
7244 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7246 * Fixed some minor bugs in client when sending WHOIS command. The
7247 arguments was in wrong order.
7249 * Removed statis function add_to_channel from server in
7250 silcd/command.c that was previously used with the joining but
7253 * Tested USERS command in router environment successfully with two
7254 routers, two servers and two clients.
7256 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7258 * Reorganized the USERS command and command reply in client library
7259 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
7260 When the command is given by user we register a pending command
7261 callback that will reprocess the command after the reply has been
7262 received from the server. When reprocessing the packet we then
7263 display the information. Thus, the USERS information is displayed
7264 now in the command callback instead of in the command reply
7265 callback. The processing of the command is same as previously
7266 when server has sent the command reply in the JOINing process.
7268 * Added to USERS command in silcd/command_reply.c to join the client,
7269 we didn't use to know about, to the channel after we've created
7270 a client entry for it. Also, for clienet we did know already still
7271 check whether it is on the channel or not and add it if not.
7273 * Removed silc_server_command_join_notify as the function and its
7276 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7278 * Changed the client's pending command handling to the same as the
7279 server's pending command handling. It is also now possible to
7280 execute command reply functions from other command reply
7281 function as the function callbacks for commands and command
7282 replies are one and same. The pending commands are not static
7283 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
7284 in client connection context. Thus, pending commands are server
7285 connection specific as it is convenient.
7287 Changed the function silc_client_command_pending and
7288 silc_client_command_pending_del and added new function
7289 silc_client_command_pending_check. Removed the
7290 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
7293 * Added cmd_ident, current command identifier, to the client
7294 connection context in lib/silcclient/client.h to keep track on
7295 command identifiers used in command sending. Client's command reply
7296 function handling now supports the mandatory command identifiers.
7298 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
7299 funtions in client to fully support pending command callbacks.
7301 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
7302 as one of the arguments to the application in the command reply
7305 * NOTE: The FORWARDED flag is depracated. It used to be depracated
7306 before first releasing SILC but came back. Now it is removed again
7307 and should come back nomore. The FORWARDED flag was used only
7308 by the JOINing procedure by forwarding the command packet to router.
7309 Now, the JOINing procedure has been changed to more generic (due
7310 to various router environment issues) and FORWARDED is not needed
7311 anymore for anything. The protocol specification is yet to be
7314 Now, removed silc_server_packet_forward from server and the flag
7315 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
7317 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7319 * Renamed NAMES command to USERS command. The NAMES was named that
7320 due to historical reasons. Now it is renamed. Also, rewrote
7321 parts of the USERS command. The nickname list is not sent anymore
7322 by the server. Only Client ID and mode lists are sent in the USERS
7323 command. Changed this also to the protocol specification.
7325 The client now resolves the names and stuff after it receives
7326 the USERS list from the server when joining to the channel.
7328 * WHOIS and IDENTIFY commands has been changed to support multiple
7329 Client ID's per command. One can now search for multiple users
7330 in the network by sending only one WHOIS or IDENTIFY command.
7331 Changed the code and the protocol specifications.
7333 * Removed silc_server_command_identify_parse and changed that IDENTIFY
7334 uses silc_server_command_whois_parse to parse the request. */
7336 * If normal server, do not parse the WHOIS and IDENTIFY requests
7337 before sending it to the router. Saves some time.
7339 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7341 * Fixed JOIN command on client library. Wrong number of arguments
7342 used to crash the client.
7344 * Added silc_server_channel_has_global function to check whether
7345 channel has global users or not.
7347 * Added silc_server_channel_has_local function to check whether channel
7348 has locally connected clients on the channel.
7350 * The silc_server_remove_from_one_channel now checks whether the
7351 channel has global users or not after given client was removed from
7352 the channel. It also checks whether the channel has local clients
7353 on the channel anymore. If it does not have then the channel entry
7354 is removed as it is not needed anymore.
7356 * The silc_server_notify now checks on JOIN notify whether the joining
7357 client is one of locally connected or global. If it is global then
7358 the channel has now global users on the channel and that is marked
7359 to the channel entry. Also, it now saves the global client to
7360 global list who is joining and JOINs it to the channel. This is
7361 for normal server, that is.
7363 Changed silc_server_send_notify_on_channel,
7364 silc_server_packet_relay_to_channel and
7365 silc_server_packet_send_to_channel check if we are normal server
7366 and client has router set (ie. global client) do not send the
7367 message to that client, as it is already routed to our router.
7369 * Implemented LEAVE notify type handling in silc_server_notify
7372 * Tested LEAVE command in router environment successfully. Tested
7373 with two routers, two servers and two clients.
7377 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
7379 * Implemented SIGNOFF notify type handling in silc_server_notify
7382 * silc_server_remove_id now removes the client entry from all channels
7383 it has joined and thusly sends SIGNOFF notify type.
7385 * Rewrote the NAMES list generation in server by removing two excess
7386 loops. The lists are created now inside one loop.
7388 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7390 * silc_server_remove_channel_user checks now also global list
7391 for channel and client.
7393 * silc_server_new_channel_user checks now both local and global
7394 list for channel and client. Fixed a bug in client id decoding.
7395 Used to decode wrong buffer.
7397 * silc_server_channel_message checks now both local and global
7398 list for channel entry.
7400 * Tested channel joining (hence JOIN) in router environment
7401 successfully. Tested with two routers, two servers and two
7404 * Tested channel message sending in router environment successfully.
7406 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7408 * Added silc_server_save_channel_key into server.[ch] to save the
7409 received channel key in Channel Key payload processing. It is
7410 also used in JOIN command reply handling.
7412 Equivalent function silc_client_save_channel_key added into
7413 client.[ch] into client library.
7415 * Changed JOIN command reply to send information whether the channel
7416 was created or not (is existing already) and the channel key
7417 payload. Changed protocol specs accordingly.
7419 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
7420 the request was sent by ID and not by nickname. Crashed on
7423 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7425 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
7426 now correctly save the received data.
7428 * silc_server_free_sock_user_data now notifies routers in the
7429 network about entities leaving the network.
7431 At the same time implemented functions silc_server_remove_id
7432 and silc_server_send_remove_id to receive and send REMOVE_ID
7433 packets. The packet is used to notify routers in the network
7434 about leaving entities. The ID removed will become invalid in
7437 * Added function silc_idlist_del_server into server. Removes and
7438 free's server entry from ID list.
7440 * silc_server_private_message function now checks, if we are router,
7441 that the destination ID really is valid ID, naturally.
7443 * In router when NEW_ID packet is received (for new client) the
7444 hash of the Client ID is saved in the ID Cache but the
7445 client->nickname is set to NULL, instead of putting the hash
7448 IDENTIFY command now also checks that client->nickname must be
7449 valid. If it is not if will request the data from the server who
7450 owns the client. Added new function
7451 silc_server_command_identify_check.
7453 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
7454 to set the command to already allocated Command Payload.
7456 * Tested private message sending in router environment with two
7457 routers, two servers and two clients. Fixed minor bugs and now
7460 * Fixed segfault from client's NAMES command. Used to crash if
7463 * Forwarded packets must not be routed even if it is not destined
7464 to the receiver. Changed server code comply with this.
7466 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7468 * Added `require_reverse_mapping' boolean value to ServerParams
7469 structure. If TRUE (not default) the server will require that
7470 the connecting host has fully qualified domain name.
7472 If the reverse mapping is not required and hostname could not be
7473 found the IP address is used as hostname.
7475 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7477 * Implemented version string checking to both client and server.
7478 The check is incomplete currently due to the abnormal version
7479 strings used in development version of SILC.
7481 * Changed all command functions in server to use the new
7484 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7486 * Changed char *data to unsigned char *data in ID Cache system to
7487 support binary data as ID Cache data. Changed code to support
7488 binary data in lib/silccore/idcache.c.
7490 * Renamed silc_server_packet_relay_command_reply to
7491 silc_server_command_reply as it is normal packet receiving
7492 function. Rewrote the function to accept command replys for
7493 servers and not only for clients.
7495 * Mark remote router always as registered server if we are connecting
7496 to it. Otherwise, commands sent by the router to us are ignored.
7498 * All ID List find routines now returns the ID Cache Entry pointer
7499 as well if requested.
7501 * WHOIS command works now in router environment, tested with two
7502 routers, two servers and two clients.
7504 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
7505 in router environment (as it is almost equivalent to WHOIS) but
7506 hasn't been tested thoroughly. Added new functions:
7508 silc_server_command_identify_parse
7509 silc_server_command_identify_send_reply
7510 silc_server_command_identify_from_client
7511 silc_server_command_identify_from_server
7513 * Disabled route cache adding because adding two different ID's with
7514 same IP replaces the old cache entry thus giving wrong route.
7515 The entry->router->connection is always the fastest route anyway
7516 so route cache may not be needed. Of course, new routes maybe
7517 established after receiving the ID when the entry->router->connection
7518 might not be anymore the most optimal.
7520 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7522 * Add route cache for received ID for fast routing.
7524 * Added silc_server_packet_route to route received packet on router
7525 that is not destined to us.
7527 * Renamed silc_server_get_route to silc_server_route_get.
7529 * Added id_string and id_string_len fields into SilcServer to
7530 include encoded ServerID for fast comparing without excess
7531 encoding of the ID's.
7533 * Cleaned up WHOIS command on server side. Added following static
7536 silc_server_command_whois_parse
7537 silc_server_command_whois_check
7538 silc_server_command_whois_send_reply
7539 silc_server_command_whois_from_client
7540 silc_server_command_whois_from_server
7542 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
7543 arguments in command replies. All command functions should be
7544 updated to use this macro.
7546 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7548 * Minor typo fixes on command reply handling on server.
7550 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7552 * Added silc_server_command_add_to_channel internal routine to add
7553 the client to the channel after router has created the channel and
7554 sent command reply to the server.
7556 * Added generic silc_server_send_command to send any command from
7559 * Use static buffer with ID rendering instead of duplicating data.
7561 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7563 * Fixed a channel user mode bug when joining to a channel server gave
7564 everybody channel founder rights, oops.
7566 * We mark ourselves as the router of the incoming server connection
7567 if we are router ourselves. This way we can check in some packet
7568 sending functions whether it is locally connected server. For
7569 incoming router connections we put NULL.
7571 * For router sending packets locally means now always sending the
7572 packet cell wide; to local clients and local servers. For normal
7573 server sending packet locally means sending it to only local
7576 * Fixed the JOIN command to really work in router environment. If the
7577 channel is created it is always created by the router. Router is
7578 also responsible of making the initial joining to the channel,
7579 sending JOIN notify to the sending server and distributing
7580 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
7581 does not exist server doesn't do anything else but forward the
7582 command to the router which performs everything.
7584 * Added silc_server_send_channel_key function to send the Channel Key
7587 * Added silc_server_create_channel_key to create new channel key. The
7588 channel key is now re-generated everytime someone joins or leaves
7589 a channel, as protocol dictates. Note: channel->key_len is the
7592 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7594 * Splitted server.[ch] finally. Created now packet_send.[ch] and
7595 packet_receive.[ch] to separate packet sending and receiving
7596 routines. The server.[ch] now includes everything else including
7597 actual packet processing (writing and reading data) and other
7600 Renamed silc_server_private_message_send_internal to
7601 silc_server_send_private_message. The routine is still though
7602 used only to relay private messages as server does not send
7603 private messages itself.
7605 Renamed silc_server_new_channel to silc_server_create_new_channel
7606 and added new function sicl_server_new_channel that handles the
7607 incoming New Channel packet. Added also new sending function
7608 silc_server_send_new_channel to send New Channel Payload.
7610 * Added new function silc_server_notify to process incoming notify
7611 packet to the server/router. Server may then relay the notify
7612 to clients if needed.
7614 * Added new function silc_server_new_channel_user to process incoming
7615 New Channel User packet. Router will redistribute the packet and
7616 send JOIN notify to its local clients and locally connected servers
7617 if needed. Normal server will send JOIN notify to its local client
7618 on same channel when received this packet. Added also corresponding
7619 sending function silc_server_send_new_channel_user to sent the
7622 * Added boolean route argument to send_notif_to_channel and
7623 packet_send_to_channel functions to attempt to route the packet
7624 if it is TRUE and send only locally if it is FALSE.
7626 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7628 * silc_server_replace_id now broadcasts the received replace ID
7629 packet if it is not broadcast packet already. The router must
7630 broadcast to inform other routers about changed ID.
7632 * Added backpointer to server's router into SilcServer context in
7633 silcd/server_internal.h.
7635 * Fixed silc_server_packet_broadcast to send correct broadcast
7638 * The channel key is now distributed to the local client as soon
7639 as it is received from the router (in router environment) so that
7640 no other packet may be sent for the channel until client has
7643 * silc_server_remove_channel_user now broadcasts the received
7644 Remove Channel User packet if it is not broadcast packet already.
7645 The router must broadcast to inform other routers about removed
7648 * Added users field into SilcPacketContext that is a reference count
7649 of the context. One can increase the reference count by calling
7650 silc_packet_context_dup which is now changed to just increase the
7651 reference count instead of duplicating the data. The reference
7652 count is decresed by calling silc_packet_context_free that will
7653 free the data after the reference count hits zero.
7655 For now on the packet context and everything allocated into it
7656 (including the raw packet from network) must be freed by calling
7657 the new silc_packet_context_free function. Added also new function
7658 silc_packet_context_alloc that must be used now to allocate the
7659 context. This also means that if a routine is asynchronous from
7660 silc_[client/server]_packet_parse_type the packet context must
7661 be duplicated by calling silc_packet_context_dup. Otherwise it
7662 gets free'd after silc_[client/server]_packet_parse_type returns.
7663 Also, one must remember that if packet is duplicated then its
7664 reference count must be decresed by calling the free function as
7665 many times as it was duplicated.
7667 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7668 from both client and server.
7670 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7672 * Made joining to a channel working in router environment.
7674 * Cleaned up JOIN command on server side and create function
7675 silc_server_command_join_channel internal routine to make the
7678 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7680 * Changed silc_command_pending list to SilcDList. Also, added
7681 `ident' field to SilcServerCommandPending structure to identify
7682 the reply and to call correct callback.
7684 Added silc_server_command_pending_check function to replace the
7685 corresnponding macro. The silc_command_pending list is not
7688 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7689 to set identifier to previously allocated Command Payload. It
7690 is used to set identifier for command when resending Command
7693 * Added silc_command_payload_encode_payload to encode Command
7694 Payload buffer from SilcCommandPayload structure.
7696 * Added silc_argument_payload_encode_payload to encode Argument
7697 payload buffer from SilcArgumentPayload structure.
7699 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7701 * Changed WHOIS command to support router connection on server side.
7702 The whois request is always sent to router unless the server is
7703 standalone server. After server has received the reply from the
7704 router will it send the reply to the client.
7706 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7707 broadcast received broadcast packet. The function is used only
7708 by router. The broadcast packet is always sent to the router's
7711 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7712 render given ID to printable string, for log files for example.
7714 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7716 * Made basic router to router connections working. At least they
7717 can now connect to each other but nothing really works the way
7718 they are supposed - yet.
7720 * Added new initiator token to RouterConnection configuration
7721 file in silcd/serverconfig.[ch]. It is used to tell whether we
7722 are the initiator to the remote router or whether we'll expect
7723 the other end to connect.
7725 * Moved registering of listener task to silc_server_init, hence
7726 the server starts listenning as soon as it is run, even if it
7727 does not have connections to other routers. Let's see how well
7730 * Changed default connection retry timeouts for more suitable in
7733 * Removed cipher and such arguments from silc_idlist_add_client
7734 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7735 Added new function silc_idlist_add_data to add the keys and stuff
7738 * Added SilcIDListData structure and added it to SilcClientEntry
7739 and SilcServerEntry as their first field in the structure. This
7740 way we can explicitly cast the ID entries to the SilcIDListData
7741 structure and get common data for the entries. In past, we had
7742 to first check what type of connection it is and then cast it to
7743 correct ID entry type. Now, we can directly cast the opaque
7744 pointer to the SilcIDListData (no matter what ID entry it actually
7745 is) and get the data needed.
7747 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7749 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7750 in some circumstances even if threre were timeout tasks, though not
7751 IO tasks, but tasks anyway. Now fixed.
7753 * Defined SilcServerConnection structure to hold connection specific
7754 stuff about directly connected servers and routers. The definition
7755 is currently in silcd/server_internal.h. I thought about having
7756 a bit more important role fro this struct but for now it is used
7757 only when connecting to other server (or router actually).
7759 * Added connecting retry support in server when connecting to
7760 router(s). The retry feature implement exponential backoff
7761 algorithm. Also, added SilcServerParams structure to hold default
7762 parameters for server. For now, it include these retry settings
7763 and are hard coded. After server is moded to be as Silc Server
7764 Library this structure will be more important.
7766 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7768 * Changed client librarys channel->clients table to SilcList and
7769 changed code accordingly.
7771 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7773 * Changed client's channel table to SilcList and changed code
7774 accordingly. Also changed SilcChannelClientEntry to include back-
7775 pointer to the channel so that client entry can use that structure
7776 as list as well and we have fast cross-reference to the channel.
7777 This change dramatically decreased the complexity of channel
7778 handling with client entry and vice versa (removed one extra
7779 loop when searching for channel entry from many functions).
7781 * Changed server->sim from table to SilcDList and changed code
7784 * NAMES command can now be used from user interface. It will show
7785 the user list on the channel, neatly.
7787 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7788 Code now saves realname of the user if it becomes available.
7790 * Renamed configure.in to configure.in.pre and made ./prepare
7791 script to automatically add correct version string to
7792 configure.in which it creates from configure.in.pre.
7794 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7796 * NAMES command reply now shows users mode with the nickname when
7799 * Moved silc_client_ch[u]mode[_char] functions from
7800 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7801 place sucks, they are utility functions and should be in some
7804 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7806 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7809 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7813 * Added TRQ (efficient deque and list library) into lib/trq. This is
7814 a very good list library that is currently used in the SILC. Defined
7815 SilcList API over the library because I didn't like the API very
7816 much. See lib/trq/silclist.h for the API and examples of how to
7817 use the API. Fixed various places in the code to use the new
7818 SilcList API. The SilcList is meant for lists that has a structure
7819 already defined as a list. It is not suitable to add just some
7820 context to the list (in TRQ, the context is the list actually).
7822 So, I defined SilcDList that can be used for the purpose where
7823 predefined list structure does not exit. This can be used as
7824 such list. Now some context just can be added to the SilcDList.
7825 Currently this list is not used in the SILC just yet, though there
7826 are a lot places where this can replace dynamically allocated
7827 tables and I will fix these places, later, to use SilcDList.
7828 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7829 and use TRQ internally).
7831 Also fixed some annoying warning messages that the original TRQ
7832 code generated. Also minor changes to TRQ's Makefile.in.
7834 * Added support for querying by Client ID to both WHOIS and
7835 IDENTIFY commands into server, as required by the protocol.
7837 * Removed method function pointers from SilcBuffer structure. They
7838 weren't used to anything and just increased the context size for
7839 no good reason. This change also made silc_buffer_alloc and
7840 silc_buffer_free functions inline functions.
7842 * Disabled command flooding detection support until it's fixed so
7843 that it accepts commands in but does not execute them more than once
7846 * Added silc_net_localhost(), to return local hostname, into
7847 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7848 that must be initialized before calling silc_client_init.
7850 * Added new function: silc_server_send_notify_on_channels to send
7851 notify messages to all channels client has joined. It is assured
7852 that the message is sent only once per client.
7854 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7855 lib/silcutil/silcutil.[ch] as silc_format function. The new
7856 function is generic and is used by server as well, not only by
7857 the logging routines.
7859 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7860 the provided version string was not acceptable. Added new function:
7861 silc_ske_check_version into lib/silcske/silcske.h. The function
7862 must be implemented by the application (client or server) and it
7863 does not reside in the SKE library. The function checks the version
7864 string remote end sent.
7866 * Added back pointers (to opaque context and to SilcSocketConnection)
7867 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7869 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7870 duplicate packet context structure.
7872 * Changed `notify' client operation to send same arguments as client
7873 receives from server except for ID's. ID's are mapped to correct
7874 ID entry and that is returned. Also, if channel entry is not sent
7875 by server but the notify is for channel the channel entry is sent
7876 to application (otherwise application doesn't know that it is for
7877 channel (library gets it from packet's Destination ID)).
7879 * Added silc_client_remove_from_channels into client library to
7880 remove a client from all channels it has joined to. Used when
7881 received SIGNOFF notify from server. Added also new function
7882 silc_client_replace_from_channels to replace old ID entry with
7883 new ID entry on all channels. Used when received NICK_CHANGE
7886 * Fixed ID Cache list handling in silc_idlist_get_client in
7887 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7888 to get (or query) client by ID.
7890 * Updated TODO list.
7892 * Added connection authentication status message defined by the
7893 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7894 support for these into the code in client and server side.
7896 * Added generic function silc_client_send_command to send any command
7897 with variable argument list. Application should use this function
7898 to send commands if the command functions provided by the library
7899 does not suite for the application's user interface needs.
7901 * Added new `failure' client operation. Application is notified about
7902 received failure packet if client is executing a protocol. In this
7903 case the protocol's execution has failed.
7905 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7906 is required by the protocol.
7908 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7909 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7912 * Added status flag to SilcSKE object to indicate realtime status
7913 of the SKE protocol.
7915 * Application receives now exactly same command reply arguments as
7916 the library receives from server. However, if ID is received the
7917 corresponding ID entry is returned to the application (eg. Client
7918 ID is mapped to correct SilcClientEntry entry and that is returned).
7919 Changed command_reply client operation due to this change.
7921 * Changed all ID's in commands and in command replys as ID Payloads.
7922 Change affected both client and server side codes.
7924 All ID's sent in SILC network (with execption of ID's in SILC
7925 Packet header) are sent in ID Payload to support variable length
7928 * Server now notifies nick changes and notifies all clients on
7929 the channels about the new nickname (about the new Client ID,
7932 * Implemented CMODE command to change channel modes. Supports all
7933 channel modes defined by the protocol specs except ban and invite
7934 lists. (Also, private channel key mode is supported but support for
7935 setting private channel key in client is missing, thus, this mode
7936 has no effect on client side (except that server requires that the
7937 client uses private channel key and normal channel traffic does not
7940 Also, invite mode works per se, but INVITE command does not work
7941 yet correctly, so you can set channel as invite only channel but
7942 inviting clients to the channel does not work (it is yet to be
7943 thought what's the best way to do it).
7945 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7946 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7947 Implemented CUMODE command to change user's mode on the channel.
7948 Supports all modes defined by the protocol specs.
7950 * Added NAMES command reply to return users modes on the channel.
7952 * Removed unnecessary and slow ciphers from lib/silccrypt.
7954 * Set SO_KEEPALIVE option to connection sockets by default.
7956 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7958 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7959 redefined the Notify Payload into protocol specs.
7961 * Added silc_id_payload_parse_id to get ID directly from raw
7964 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7966 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7967 accept searching by Client ID as well.
7969 * Added support for LEAVE and SIGNOFF notify types in client library.
7971 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7972 to parse ID Payload from raw data.
7974 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7976 * Added flags parameter into silc_ske_assemble_security_properties
7977 function in lib/silcske/silcske.[ch].
7979 * Changed notify client operation to fit better for notify messages
7980 sent by server. The notify payload received from server is now
7981 passed to the application (after parsing it to SilcNotifyPayload).
7982 It is application's responsibility to retrieve the arguments
7983 from the payload and show the message the way it wants. The message
7984 sent by server is implementation specific.
7986 * Changed public keys to comply with the protocol specification.
7987 Old public keys are not supported anymore and are not compatible.
7989 * Removed nickname from Channel Payload as the latest draft removed
7990 it. The client must resolve the nickname from the NAMES command
7991 reply received when it joined the channel.
7993 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7995 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7997 * Fixed some errors in protocol specification drafts.
7999 * Created lib/silccore/silcnotify.c to implement Notify Payload
8000 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
8001 generic payloads described by protocol specifications. The file
8002 includes implementations for ID Payload and Argument Payload.
8004 * Changed Command Payload implementation to use the new Argument
8005 Payload. Changed command_xxxx_payload to command_payload_xxxx
8006 to comply with SILC coding conventions.
8008 * Added suppport for Argument Payload handling in Notify Payload
8009 implementation as protocol requires it. Added the new support
8010 into server and client lib as well.
8012 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8014 * Added support for multiple nicknames on same channel. [n] is
8015 added locally to the nickname if there are more than one same
8016 nicknames on the channel.
8018 * Server now sends all nicknames that matched WHOIS request.
8019 Client also shows the list received from server.
8021 * Added TOPIC command to client side. User can now set and show
8022 current topic on channel.
8024 * Added MOTD command to client and server. Also, server sends the
8025 motd when client connects to the server.
8027 * Changed version strings to comply ISO 8601.
8029 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8031 * Fixed protocol error handling in client library. It should now
8032 cope even if the SKE fails for some reason.
8034 * Made new protocol specification drafts for submitting to IETF.
8036 * Implemented TOPIC command to server in silcd/command.c.
8038 * Added two new notify types into lib/silccore/silcnotify.h:
8039 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
8040 notify nickname change and topic setting/change on a channel.
8042 * API change of command_reply operation in client library. The
8043 application gets now the status type received from server as well.
8045 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8047 * Removed the function just added to lib/silcutil/silcschedule.[ch].
8049 * Cras fixed and optimized the packet handling even further and
8050 it should work now. Minor change to the prototype of function
8051 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
8053 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8055 * Added new function into lib/silcutil/silcschedule.[ch]:
8056 silc_schedule_with_fd to select() a specified fd. The function
8057 returns after timeout expires or data arrives or goes. The
8058 function is used by packet routines to wait that all data is
8059 received from network.
8061 * Fixed data reading from network in lib/silccore/silcpacket.c.
8062 The code now assures that all data is read from the fd and then
8063 continues packet processing. This was a bug fix since the code
8064 used to drop some data in some circumstances.
8066 * Added new function into lib/silcclient/client.[ch]:
8067 silc_client_start_key_exchange to start key exchange after
8068 connection has been established to server. The code internally
8069 now uses this funtion but its main purpose was to provide it
8070 for applications that perform their own connecting. After
8071 application has created a connection it merely calls this
8072 function to start the key exchange between client and server.
8073 The library takes care of everything else after that.
8075 Updated also lib/silcclient/README to explain the usage of
8078 * Do not send to application information that connection has
8079 been established. Application gets notified it by connect
8082 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8084 * Applied cras's patch to add silc_schedule_one function. The
8085 function runs scheduler once and returns.
8087 * Fixed the scheduler after cras messed it up. The timeout
8088 handling works now as it's supposed to work.
8090 * Added into lib/silccore/ silcnotify.h to include notify
8091 message types support. Changed silc_server_send_notify*
8092 functions, in server.[ch], to support those new notify types.
8093 Added the support for the notify types into client library,
8094 as well. Added new notify client operation into ops.h in
8097 * Changed silc_server_packet_send_to_channel to send normal
8098 packets instead of just channel message packets. The function
8099 is now used to send the notify packets to channels. It is not
8100 used to send channel message packets anymore, as server never
8103 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
8104 va_arg()s as it seems to require it nowadays. I guess, if SILC
8105 is compiled with older va_arg() the new code should work anyway.
8107 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8109 * Splitted core library. Core library (lib/silccore) includes
8110 now only SILC protocol specific core (and common) components.
8111 Created new utility library (lib/silcutil) that includes more
8112 generic purpose stuff. The stuff for util library was taken
8113 from the old core library. This was minor and easy split.
8115 * Created SILC Client Library (lib/silcclient) that includes
8116 implementation of the SILC client without user interface. This
8117 was major move from silc/ directory. The code has been changed
8118 so that it is transparent towards the user interface. The
8119 silc/ directory includes now the same user interface as before
8120 and it uses the new client library. Read lib/silcclient/README.
8121 Basicly, the client library performs everything else related
8122 to SILC except user interface handling. Also, configuration
8123 files are considered to be part of user interface and library
8124 does not handle them.
8126 This change also changed a lot of structures, function naming etc.
8127 Most important change was that SilcClientWindow object was
8128 renamed to SilcClientConnection in the client library. Created
8129 also new file lib/silcclient/ops.h. Also added new files
8130 silc/local_command.[ch] and silc/client_ops.[ch].
8132 All these changes were made to make it easier for user interface
8133 designers to create what ever user interface for the SILC client
8136 It is also expected that the server will be moved to lib
8137 directory as well and SILC Server Library will be created;
8138 sometimes in the future.
8140 * Removed Local commands from lib/silccore/silccommand.h as
8141 they are application specific and new client library does not
8142 handle any of those anymore.
8144 * Several functions moved to lib/silcutil/silcutilc.[ch] from
8145 old client implementation in silc/.
8147 * Added support for callback functions in SILC_LOG_* macros.
8148 Application can now set its own callbacks that will be called
8149 instead of using the default functions that will always print
8150 the debug messages to stderr (or stdout). Also, debugging can
8151 now be disabled by setting silc_debug to FALSE and re-enabled by
8152 setting it to TRUE. Note, that logging will still work even
8153 if debugging is disabled.
8155 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
8156 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
8157 silc_log_reset_debug_callbacks.
8159 * To enable debugging in silc client one must give now -d
8160 option on command line.
8162 * Changed silc_schedule_init to automatically allocate task queues
8163 if they are not allocated before calling it.
8165 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8167 * Added GMP 3.1 into math library.
8169 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8171 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
8172 a channel in SILC network. The packet is used by servers and
8173 routers to notify other routers that user has left a channel.
8174 This little feature was missing until now. Added the feature
8175 to protocol specification as well.
8177 Added functions: silc_server_send_remove_channel_user and
8178 silc_server_remove_channel_user into server.[ch].
8180 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
8181 lib/silccore/silcpacket.h. However, they are not implemented
8184 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8186 * Fixed joining to a channel and sending channel messages
8187 between server and router. The channel message sending should
8188 now work inside a cell.
8190 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8192 * Fixed the private message sending between server and router.
8193 The private message sending should now work inside a cell.
8195 * Added silc_server_replace_id into server.[ch] to replace
8196 existing ID in the SILC network.
8198 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
8199 and silc_idlist_replace_server_id into idlist.[ch] in server.
8201 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8203 * Fixed the server to server connections. Server can again now
8204 connect to router. Router to router connections probably does
8207 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8209 * Added dynamic protocol registering support. Now protocols can
8210 registered and unregistered on the fly. Patch by cras.
8212 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8214 * Added lib/contrib directory to hold routines that some platforms
8215 don't have but are needed by SILC.
8217 * Added getopt.c, getopt1.c and getopt.h from GNU C library
8218 into lin/contrib to provide getopt() and getopt_long() for
8219 those who don't have it.
8221 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8223 * Added AWAY command to client. When away message is set and
8224 client receives a private message packet the client automatically
8225 replies to the sender with the away message.
8227 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
8228 bug seemed to be the cause of recent problems when compiling
8231 * Added version detection support to SKE protocol specification
8232 and added the new changes to the SKE implementation as well.
8233 There were other minor changes in the SKE protocol as well.
8235 Many changes in lib/silcske/silcske.[ch] and in
8236 lib/silcske/payload.[ch].
8238 * Added ^U functionality, clear input line. Patch from cras.
8240 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8242 * Mainly small bugfixes on core library. Fixed some debugging
8243 logging and buffer overflow in silclog.c.
8245 * Updated config.sub and config.guess on the distribution tree.
8247 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8249 * Added command lagging support in server. Client may execute
8250 commands now only once in two seconds.
8252 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8254 * Optimized packet reception. MAC computation and checking is now
8255 also more optimized. A lot previously duplicated code is now
8256 used as generic by both client and server.
8258 * Fixed key pair generation in clientutil.c
8260 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8262 * Added into lib/silccore/silcbufutil.[ch] new function;
8263 silc_buffer_realloc.
8265 * Moved generic packet sending/encryption functions to
8266 lib/silccore/silcpacket.[ch] from client and server. Some
8267 rewriting of the functions.
8269 * Moved all generic packet reception/decryption functions to
8270 lib/silccore/silcpacket.[ch] from client and server. The
8271 packet processing is now much cleaner in both client and server.
8272 These were major changes in both client and server.
8274 * Created many common functions in server to do packet sending.
8275 Previously code were duplicated a lot, this has been removed
8278 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8280 * Rewrote major parts of the ID cache system. Don't know
8281 whether it is better now or not but at least the API is more
8284 * Major rewrite on ID cache stuff on client because of the ID
8285 cache API changes. Added idlist.c to client.
8287 * Also major rewrite on ID cache stuff on server as well.
8288 Major rewrite of idlist.[ch]. SilcXXXList's are now named
8289 SilcXXXEntry's. We won't keep anymore idlist specific pointers
8290 in hand, instead they are all put into the ID cache system now.
8291 All server_idlist_* routines uses ID cache now instead of
8292 traversing its own lists (those lists does not exist anymore).
8293 SilcIDList though still exists. Also, SilcXXXEntry's are
8296 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8298 * Finally made the SKE implementation compliant to the protocol
8299 specification. All mp integers are now binary encoded as
8300 opposed being HEX encoded.
8302 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
8305 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
8306 functions: silc_[encode/decode]_pem. Also added function
8307 silc_encode_pem_file to PEM encode with newlines ('\n') for
8310 * SILC public keys are now encoded either PEM or binary. Same
8311 option is for private keys as well. By default private keys
8312 are binary encoded and public keys PEM encoded. Silly HEX
8313 encoding were removed.
8315 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
8316 function to create fingerprints.
8318 * Fixed a bug in SHA1; does not change the original data anymore.
8320 * Partly implemented INFO command on client and server side.
8321 Fixed CLEAR command. Changes to SERVER command; show current
8322 server(s) when giving command without arguments. Added
8323 VERSION command to client.
8325 * Added check to server that unregistered connections cannot
8326 execute commands (unless it is specificly allowed).
8328 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8330 * Fixed screen refresh.
8332 * Fixed channel joining bug from client. On some circumstances
8333 client tried to join to a channel it had already joined.
8335 * Added public key verification process into client's protocol.c.
8336 The client now verifies the public key from user and saves
8337 it into ~./silc/serverkeys/ directory.
8339 Added into: clientutil.[ch]: silc_client_verify_server_key.
8341 * Changed SKE protocol's silc_ske_initiator_finish function
8342 to accept callback function that verifies the received public
8343 key. Removed old silc_ske_verify_public_key function.
8345 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8347 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
8348 silc_pkcs_private_key[_data]_set.
8350 * Made the password and public authentication more cleaner in
8351 server's protocol.c.
8353 * Removed historic and obsolete protocol `channel_auth' from
8354 both client and server.
8356 * Removed wrong way of sending command status messages from
8357 server to client in server's command.c. The old way violated
8358 protocol specification.
8360 Changes to silccore/silccommand.[ch]: removed
8361 silc_command_encode_status_payload -> not needed anymore,
8362 changed silc_command_encode_payload_va to accept extra
8363 argument on variable argument list. The argument type must
8364 now be provided to the function. Also, added new function:
8365 silc_command_encode_reply_payload_va which is same as
8366 normal command_encode_payload_va except command status type
8367 is provided as extra argument.
8369 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8371 * Added ~./silc directory handling. The directory includes the
8372 public and private keys for the client.
8374 Added silc_client_check_silc_dir, silc_client_create_identifier
8375 and silc_client_load_keys.
8377 * Implemented SILC protocol compliant public key. Added public
8378 and private key saving to and loading from files.
8380 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
8381 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
8382 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
8383 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
8384 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
8386 Implemented: silc_pkcs_save_[public/private]_key[_data] and
8387 silc_pkcs_load_[public/private]_key.
8389 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8391 * Added silc_server_get_route (route.[ch]) to get connection
8392 data for the fastest route for given ID.
8394 * Implemented INVITE command on client and server. The command
8395 were re-defined in the SILC Protocol Specification and the
8396 implementation now complies with the specification.
8398 * Implemented PING command on client and server.
8400 * Implemented NAMES command on client and server. The server side
8401 supports currently only normal server not router server yet.
8402 Some changes to NAMES definition in SILC protocol specification.
8404 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8406 * Implemented LEAVE command on client and server.
8408 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
8409 again. This change was made to the protocol as well. Server
8410 should not violate the protocol specification anymore.
8412 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8414 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
8415 was tested. SOCKS4 was not but should work anyway.
