534 Wed Apr 10 16:32:01 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
536 * Changed the CMODE's mode mask argument to be optional. If
537 not provided then the command merely returns the current mode
538 mask to the client. Updated protocol specs and the server.
539 Affected file is silcd/command.c.
541 * Changed the Killer's Client ID in KILLED notify to be just
542 any ID payload since router server is allowed to kill as well.
543 Updated protocol specs, client libary and server. Affected
544 files are lib/silcclient/client_notify.c, silcd/packet_receive.c,
545 and irssi/src/silc/core/client_ops.c.
547 Tue Apr 9 17:15:42 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
549 * Added new user modes ANONYMOUS for special anonymous servers
550 that may set the mode for client, and BLOCK_PRIVMSG which
551 client may set to block incoming private messages unless the
552 Private Message Key flag is set (using private keys to protect
553 private messages). Updated protocol specs and code in client
554 and server and core library. Protocol TODO #23. Affected
555 files are lib/silccore/silcmode.h, silcd/server.[ch],
556 irssi/src/silc/core/client_ops.c, silcd/packet_receive.c,
557 irssi/docs/help/in/umode.in, lib/silcclient/command.c.
559 * Added new channel user mode BLOCK_MESSAGES which the client
560 may set to itself to tell server not send channel messages.
561 Other packets such as channel key packets are still sent.
562 Protocol TODO #23. Updated the protocol specs, client and
563 server. Affected files are lib/silccore/silcmode.h,
564 irssi/docs/help/in/cumode.in, lib/silcclient/command.c,
565 lib/silcutil/silcutil.c, silcd/command.c, and
568 Mon Apr 8 23:57:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
570 * Redefined the Status Payload to include now two 8 bit fields,
571 instead of one 16 bit field. This now makes it possible to
572 send list of errors. Updated the protocol specs and the code
573 in core library, client library and server. Protocol TODO #1.
574 Affected files are lib/silccore/silccommand.[ch],
575 lib/silcclient/command_reply.[ch], silcd/command.c,
576 silcd/command_reply.c and silcd/packet_receive.[ch].
578 Mon Apr 8 19:57:40 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
580 * Added config parse status SILC_CONFIG_EPRINTLINE, this status
581 must be handled by the application and should tell the application
582 that an error message was already printed, and it should print the
583 config coords (line, filename, ...). Affected files are
584 silcd/serverconfig.c, lib/silcutil/silcconfig.[ch].
586 * Added local macro SILC_SERVER_CONFIG_ALLOCTMP to make the
587 server config parsing code more readable.
589 Fixed a bug in the fetch_logging() config callback.
591 Affected files is silcd/serverconfig.c.
593 * Drop root privileges when started in foreground. Don't drop them
594 if debugging also. Affected file is silcd/silcd.c.

602 lib/silccore/silcmode.h, irssi/src/silc/core/client_ops.c,
603 irssi/docs/help/in/umode.in and lib/silcclient/command.c.
605 Sun Apr 7 17:07:59 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
607 * Added STATS command to the protocol after all, to return
608 various statistical information about the network. It can
609 be used by clients to retrieve statistical information, and
610 servers may use it to to fetch cell and network wide
611 statistics from router. Updated the protocol specs and
612 implemented it to the server. Protocol TODO #16.
613 Affected files are lib/silccore/silccommand, silcd/command.[ch],
614 silcd/command_reply.[ch].
616 Sat Apr 6 17:08:58 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
618 * The LIST command reply in client libary now adds new channel
619 entry if the returned channel doesn't exist yet in cache,
620 and returns the channel entry to the application in the
621 command_reply client operation. Affected file is
622 lib/silcclient/command_reply.c.
624 * Changed the channel message payload's MAC generation to
625 include the IV in the MAC as well. This way all relevant
626 parts of the channel message payload are authenticated also
627 with the channel message MAC (and not only by packet MAC).
628 Causes incompatibility with 1.0 protocol. Protocol TODO #7.
629 Affected file is lib/silccore/silcchannel.c.
631 * Fixed the SKE to save the remote version, since the
632 silc_ske_parse_version mistakenly checked wrong version,
633 after it replaced the start payload. Affected files are
634 lib/silcske/silcske.[ch].
636 Fri Apr 5 16:03:03 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

641 Affected files lib/silcutil/silcstrutil.[ch].
643 * Renamed silc_*_pem functions to silc_pem_* functions. Affected
644 files are lib/silcutil/silcstrutil.[ch].
646 * Defined that the security property fields in SKE SHOULD be
647 UTF-8 encoded, defined that version string MUST be US-ASCII
648 encoded, defined that passphrases sent in connection
649 authentication protocol MUST be UTF-8 encoded. Implemented
650 these to the client and server. Defined also that other
651 passphrases sent in the protocol MUST be UTF-8 encoded.
652 Affected files are lib/silcske/silcske.c,
653 lib/silcclient/protocol.c, silcd/protocol.c,
654 silcd/serverconfig.c, and lib/silccore/silcauth.c.
656 * Changed the silc_client_close_connection interface to not
657 need the SilcSocketConnection which should not be visible
658 to application. Affected files are lib/silcclient/client.c
659 and lib/silcclient/silcclient.h.
661 * Rewrote the text for Private Message Key Payload in the
662 protocol specification. Protocol TODO #11.
664 Wed Apr 3 16:24:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
666 * Upgraded the protocol version to 1.1, updated protocol specs
669 * Added the nickname as new argument to NICK_CHANGE notify and

680 The killer's client entry is now returned to application in
681 the `notify' client operation.
683 * Fixed the Max Argument fields that had too large value set
684 in the protocol specs. Protocol TODO #14.
686 * Added the LEAVE command reply to return the ID of parted
687 channel. Updated protocol specs and implemented it to the
688 client and server. Protocol TODO #15. Affected files are
689 silcd/command.c, lib/silcclient/command_reply.c. The channel
690 entry is now returned to application in the `command_reply'
693 * Rewrote the version SKE version checking in client libary
694 and in server to use the silc_parse_version_string. Affected
695 files are lib/silcclient/protocol.c, silcd/protocol.c.
697 * Added SILC_STATUS_ERR_NO_CHANNEL_FOPRIV error status to few
698 commands that was missing it, and updated protocol specs and
699 the server implementation. Protocol TODO #10. The affected
700 file is silcd/command.c.
702 * Defined new message flags SILC_MESSAGE_FLAG_REPLY to be
703 generic reply to a generic request (REQUEST flag), and
704 SILC_MESSAGE_FLAG_DATA to send any kind of data in a generic
705 way. A draft-riikonen-silc-flags-payloads-00.txt is written
706 to define the payload for DATA flag. Added the flags to
707 the implementation. Protocol TODO #9. Affected file is
708 lib/silccore/silcchannel.h.
710 Changed the client library to return the message length
711 to application as well in the channel_message and private_message
712 client operations. Affected files are
713 lib/silcclient/client_prvmsg, lib/silcclient/client_channel.c,
714 lib/silcclient/silcclient.h, irssi/src/silc/core/client_ops.c,
715 and lib/silcclient/client_ops_example.c.
717 * Added two new channel modes: SILC_CMODE_SILENCE_USERS
718 and SILC_CMODE_SILENCE_OPERS which can be used to moderate
719 the channel. Updated protocol specs and impelemented this
720 to client and server. Protocol TODO #6. Affected files are
721 silcd/packet_receive.c, server_util.c, lib/silcclient/command.c,
722 lib/silcclient/client_channel.c, lib/silccore/silcmode.h.
724 Added new options m and M to CMODE command in Irssi SILC
725 client to set these modes.
727 * Deprecated all administrative commands from SILC protocol
728 since they are highly implementation specific commands.
729 Updated protocol specs. Moved the old commands in
730 implementations to private range of command types. Affected
731 files are silcd/command.c, lib/silcclient/command.c and
732 lib/silcclient/command_reply.c. Protocol TODO #8.
734 * Fixed a bug in server where sending unknown command crashes
735 the server. Affected file silcd/command.c.
737 Wed Apr 3 09:57:47 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
739 * Added SILC_PROTOCOLVERSION macro to check protocol version
740 of a socket connection. The affected file is
741 lib/silcutil/silcsockconn.h.

750 Affected file silcd/protocol.c.
752 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
754 * Some client implementations quit network by doing first LEAVE
755 and then immediately SIGNOFF (like Bombyx). We now do check
756 after a short time after LEAVE notify and check whether the
757 client is still valid after LEAVE, and if not we remove it from
758 cache. Affected file is lib/silcclient/client_notify.c.
760 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
762 * Merged version 1.1.4 of zlib. Even if it not currently in use,
763 it's good not to have security holes here.
765 * Fixed a negative refcount situtuation for the config context.
766 Affected file is silcd/serverconfig.c.
768 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
770 * ROBOdoc documented lib/silcutil/silcutil.h.
772 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>

775 totally saved 16 bytes of memory per context after optimization.
776 Affected files are lib/silccore/silcpacket.[ch].
778 * Made strict checks for valid SILC IDs. Affected file is
779 lib/silccore/silcid.c.

788 * Changed the silc_get_username and silc_get_real_name to
789 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
791 * Fixed the Irssi SILC Client to use the silc_get_username and
792 silc_get_real_name insted of glib routines since the glib
793 routines only corrupt stack. Fixes the Irssi SILC to work in
794 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
796 * Fixed the Irssi to not use g_get_home_dir since it crashes
797 or returns garbage on cygwin and corrupts stack. Added function
798 get_home_dir to Irssi routines. Affected files are
799 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
801 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>

805 SilcPacketContext structure.
807 Affected files lib/silcsftp/sftp_fs_memory.c,
808 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
810 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
812 * And yet again reverted back the config thing since Johnny
813 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
816 * Fixed memory leaks from config object. Affected files are
817 silcd/serverconfig.[ch].
819 * Added support for adding new connections to the server in rehash.
820 After rehash they take effect.
822 Added support for changing the maximum allowed connections in
823 rehash. The number can grow but going smaller is not supported.
825 Added function silc_server_num_sockets_by_remote to the
826 silcd/server_util.[ch].
828 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
830 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
832 * Added preliminary checking during config parsing for a valid
833 public/private key and removed further checks in the code.
834 Affected files are silcd/serverconfig.[ch], server.c.
836 * Moved functions silc_server_drop() and silc_server_daemonise()
837 from server.c to silcd.c since they are stricly related to
838 the application activity.
840 * Reverted a small part of the automatic ref/unref since
841 it caused a double unref in some situations. Affected
842 files are silcd/silcd.[ch], server.c, serverconfig.c.
844 * Added some .cvsignore files in the lib directory.
846 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
848 * Fixed silc_net_gethostbyaddr to correctly resolve by
849 address. Affected file lib/silcutil/silcnet.c.
851 * Fixed the notify relaying to client. The HMAC to be used
852 with relayed packets ws wrong and caused decryption failure
853 at the client end. Affected file is silcd/packet_receive.c.
855 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
857 * Created new branch silc_protocol_1_0_branch.
859 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
861 * Changed the silc_server_config_* routines to be SilcServer
862 independent. They are now officially application specific code
863 and not part of generic server implementation. Affected files
864 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
866 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
868 * Added automatic referencing of config context in the
869 silc_server_config_alloc, and automatic unreferencing in the
870 silc_server_config_destroy. Affected files are
871 silcd/serverconfig.[ch], silcd/silcd.c.
873 * Fixed the silc_log_quick handling in the logging routines.
874 It didn't log quickly when it was TRUE. Affected file is
875 lib/silcutil/silclog.c. Also the flush delay was set even
876 if it was 0 in config file. Affected file is
877 silcd/serverconfig.c.
879 * Added support for changing key pair of the server in rehash.
880 Affected file silcd/server.c.
882 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
884 * Fixed the TOPIC_SET notify to not cras. It changed the topic
885 too early, before getting the channel entry. Affected file
886 is silcd/packet_receive.c.
888 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
890 * Added functions silc_server_config_[ref/unref], these are used
891 to prevent that the config object is destroyed.
893 No longer directly affect global variables silc_log_quick and
894 silc_log_delay, they are first cached inside the config object
895 and then applied with silc_server_config_setlogfiles().
897 silc_server_config_set_defaults() is now internal to
898 serverconfig.c, there are no reasons to show this internal stuff
901 Affected files are silcd/serverconfig.[ch].
903 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
904 fprintf's to stderr, since some code may be executed again after
905 the server went into the background. Affected files are
908 * Added rehash support. Added function silc_server_rehash() that
909 will perform all the basic tasks of the rehashing procedure.
911 * Added command line option `-x, --hexdump'. This will enable the
912 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
913 The option `--hexdump' implies `--debug'.
915 * Fixed a bad bug in the logging APIs (silcutil library) where
916 the application would crash after calling silc_log_reset_all().
918 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
920 * Fixed the KICKED notify handling in client library to
921 correctly remove the channel and all entries from the
922 channel when I was kicked. This bug crashed the client.
924 Fixed yet another but in KICKED notify handling to remove
925 the kicked client correctly from the channel.
927 Affected file is lib/silcclient/client_notify.c.
929 * Fixed a minor bug in looking up correct client entry
930 in KICKED notify in server. Affected file is
931 silcd/packet_receive.c.
933 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
934 sources correctly to distribution. Fixes --with-gmp option.
936 * Removed the manual rehashing from ID Cache, and changed it
937 to use the SILC Hash Table's auto rehash feature. Affected
938 file is lib/silccore/silcidcache.c.
940 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
942 * Fixed a bug in the silc_client_nickname_format function that
943 handles the multiple same nickname formatting. Two clients
944 with same nickname caused problems after the first one left
945 and rejoined. It didn't format the nickname correctly.
946 Affected file is lib/silcclient/idlist.c.
948 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
950 * Don't change the topic if olod topic is same as new one.
951 Affected file is silcd/packet_receive.c.

956 generator. All types across all HTML files are now cross-
957 referenced. Affected files util/robodoc/generator.c and
958 scripts/silcdoc/silcdoc.
960 * Added file lib/silcutil/silctypes.h to include all the
961 arithmetic type definitions and some macros. Removed
962 includes/bitmove.h and moved macros to silctypes.h.
964 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
966 * Merged bugfixes for Irssi SILC client from irssi.org CVS.

993 allowed by the client. Affected file silcd/packet_receive.c.
995 * Created function silc_get_input which can be used to get input
996 (echo on or off) from user on command line. Affected files are
997 lib/silcutil/silcutil.[ch].
999 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1001 * Optimized silc_server_packet_relay_to_channel function.
1002 Added new function silc_channel_message_payload_encrypt which
1003 can be called directly if channel message payload needs to
1004 be encrypted and is already encoded (no need to call _encode
1005 function). Packet relaying is now done by router without any
1006 extra memory allocations. Affected files are
1007 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
1008 silcd/packet_send.c.

1028 by the client. Affected files are silcd/server_util.[ch],
1029 silcd/packet_receive.c and silcd/command.c.
1031 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1033 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
1034 ID length. It ignored that ID can be IPv6 based as well.
1035 Affected file lib/silccore/silcpacket.h.
1037 * Fixed the silc_id_id2str and silc_id_str2id to take the
1038 IPv6 address offset's into consideration. Affecte file is

1044 NULL context they may receive. The affected file is
1045 lib/silcutil/unix/silcunixschedule.c.
1047 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
1049 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
1050 can specify different directory with --home command line
1051 parameter. Affected files irssi/src/silc/core/client_ops.c,
1054 * SILC-specific commands aren't now executed if the active server
1055 isn't of SILC-type, so there won't be problems with having
1056 IRC and SILC protocol support in same client. Affected files
1057 irssi/src/silc/core/silc-channels.c, silc-servers.c,
1060 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1062 * Improved the signal support in SILC Schedule. Added new
1063 function silc_schedule_signal_call which is used by application
1064 to mark a signal to be called. It is now safe to perform
1065 any kind of tasks in signal callbacks since it is guaranteed
1066 that the application specified signal callback is called
1067 after the signal is over. Affected files are
1068 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
1070 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1072 * Added `name' field to SilcChannelPrivateKey to represent
1073 application given name for the key. Moved also the context from
1074 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
1075 Added the `name' argument also to the function
1076 silc_client_add_channel_private_key.
1078 Added function silc_client_current_channel_private_key to set the
1079 current channel private key in use.
1081 Added "change" command to KEY command which can be used to change
1082 the current channel private key. Bound the command also to
1083 alt+K (Alt+Shift+k).
1085 Also affected files lib/silcclient/client_channel.c,
1086 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
1088 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1090 * Added silc_rng_get_byte_fast function in to the
1091 lib/silccrypt/silcrng.[ch].
1093 * Changed the interface of silc_packet_assemble and the
1094 silc_packet_send_prepare. If silc_packet_assmble is now
1095 called the application does not call silc_packet_send_prepare
1096 because the library will call it automatically. These
1097 interfaces now also return a reference to the outgoing buffer
1098 which includes the assembled packet, which the application can
1099 use to encrypt the packet.
1101 Affected files are lib/silccore/silcpacket.[ch],
1102 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
1103 silcd/packet_send.c, server_backup.c and packet_receive.c.
1105 * Fixed a packet sending bug on very high load, where outgoing
1106 packet queue wasn't handled correctly and packets got corrupted.
1107 Affected files are lib/silcutil/*/silc*sockconn.c,
1108 lib/silcclient/client.c and silcd/server.c.
1110 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1112 * Added macro SILC_PACKET_DATALEN which can be used during
1113 packet assembling to check whether the data to be added to
1114 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
1115 len is truncated until it fits it.
1117 Added checks for maximum length of channel message payload and
1118 private message payload also.
1120 Added checks for maximum packet length in server and in
1123 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
1124 lib/silcclient/client.c, lib/silccore/silcchannel.c and
1125 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
1126 lib/silcclient/client_prvmsg.c.
1128 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1130 * Added silc_server_packet_queue_purge call to the
1131 silc_server_disconnect_remote to assure that all data in the
1132 queue before disconnecting is sent to the network. Affected
1133 file silcd/server.c.
1135 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1137 * Added the deleting of server's own ID cache entry to the
1138 silc_server_free function. Free also everything else that
1139 has been allocated in silc_server_init. The affected file
1142 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1144 * Added functions silc_parse_version_string, silc_version_to_num,
1145 and silc_ske_parse_version to parse SILC protocol style version
1146 strings. Affected files lib/silcutil/silcutil.[ch] and
1147 lib/silcske/silcske.[ch].
1149 * Added new configuration params: version_protocol, version_software
1150 and version_software_vendor to specify what version the remote
1151 host must at least be to be able to connect to server. The vendor
1152 string can be regex matched too. Added new function
1153 silc_server_connection_allowed to check maximum number of allowed
1154 connections, and allowed versions for incoming connections.
1155 Affected files are silcd/server.c, server_util.[ch] and
1158 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1160 * Added preliminary support for signals in scheduler. The
1161 signals we care about are now blocked always when the scheduler
1162 is locked. This way we can synchronise the use of signal with
1163 scheduler. It is guaranteed that when signal occurs the scheduler
1164 is not locked, and thus new tasks can be safely added to the
1167 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
1168 to silc_schedule_internal_init and silc_schedule_internal_uninit.
1169 Added new platform specific routines
1170 silc_schedule_internal_signals_[un]block and
1171 silc_schedule_internal_signal_[un]register.
1173 Added new functions to SILC Schedule API:
1174 silc_schedule_signal_[un]register. Each signal that application
1175 is going to use should be registered to the scheduler.
1177 Affected files are lib/silcutil/silcschedule.[ch],
1178 lib/silcutil/*/silc*schedule.c.
1180 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1182 * Check for unauthenticated client and server in the
1183 silc_server_new_client and silc_server_new_server functions.
1184 Affected file silcd/packet_receive.c.
1186 * Added function silc_string_is_ascii to check whether given
1187 string is 7-bit ASCII string. Affected files are
1188 lib/silcutil/silcutil.[ch].
1190 * Added function silc_id_is_valid_server_id into the
1191 silcd/serverid.c and added checking for valid Server ID's in
1192 silc_server_new_server. The Server ID must always be based
1193 on the server's public IP address.
1195 * Added logging of DISCONNECT packet message in the server.
1196 Affected file silcd/server.c.
1198 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1200 * Changed all library interfaces that use Global RNG to also
1201 accept SilcRng as argument. Affected files are
1202 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
1203 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
1204 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
1205 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
1206 lib/silccrypt/rsa.c.
1208 * Added function silc_pkcs_generate_key to the
1209 lib/silccrypt/silcpkcs.[ch] for applications so that they
1210 don't need to do pkcs->pkcs->init calls anymore.
1212 * Remove SilcSocketConnection from the SFTP API since it really
1213 wasn't needed there. The application has the information
1214 saved in its contexts anyway and the SFTP layer doesn't need
1215 know about it. Affected files lib/silcsft/silcsftp.h and
1216 lib/silcsftp/sftp_[server/client].c.
1218 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
1219 The SilcSimContext is not SilcSim.
1221 * Fixed possible buffer overflows in silc_id_render in the
1222 lib/silcutil/silcutil.c.
1224 * On EPOC the global crypto module lists are not used at all
1225 in the crypto library. Added support for using the constant
1226 algorithm list on EPOC. Affected files are
1227 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
1230 * Fixed the handling of third parameter of KICKED notify, since
1231 it was mistakenly updated to SILC Protocol 1.0 even though it
1232 is to be included in 1.1. Since it is not in 1.0 it is not
1233 mandatory, and this fix now handles it only if it is provided,
1234 and it is not error if it is not provided. Affected file
1235 lib/silcclient/client_notify.c.
1237 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1239 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
1240 client. Affected file irssi/src/silc/core/client_ops.c.
1242 * Merged with Irssi 0.8.4 from irssi.org CVS.
1244 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1246 * Check for valid socket connection in client entries before
1247 sending any messages. Fixes a crash, but doesn't fix some
1248 other underlaying bug that is lurking there. Affected
1249 file silcd/packet_send.c.
1251 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
1253 * $usermode, $cumode and $cumode_space expandos shouldn't do
1254 anything with non-SILC server records. Affected file
1255 irssi/src/silc/core/silc-expandos.c
1257 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1259 * Fixed the silc_net_check_[host/local]_by_sock to support
1260 IPv6 bound sockets as well. Now they can return IPv6 addresses
1261 as well. Affected file lib/silcutil/silcnet.c.
1263 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
1264 Affected lib/silcutil/unix/silcunixnet.c.
1266 * Fixed ID rendering (at least on some platforms, not NetBSD)
1267 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
1269 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1271 * Added silc_hash_public_key and silc_hash_public_key_compare
1272 functions to be used with SilcHashTable. They can be used to
1273 hash public keys and compare public keys in hash table. Affected
1274 file lib/silcutil/silcutil.[ch].
1276 * Added support for specifying multiple public keys for Client
1277 connection section in server configuration file. This makes it
1278 possible to accept multiple public keys from same host, or to
1279 make a section that accepts any incoming host, and have the
1280 accepted public keys listed in the section.
1282 Added functions silc_sever_[find/get]_public_key, added the
1283 support for this actually to all connection sections but only
1284 the Client section is currently allowed to specify multiple
1287 Affected files are silcd/server.c, server_internal.h,
1288 command.c, protocol.c, server_util.[ch], packet_receive.c.
1290 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1292 * Merged Irssi 0.8.2 from irssi.org CVS.
1294 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1296 * If silc_debug is TRUE, also output standard logging messages
1297 to stderr with the debug output.
1299 Made silc_log_reset_all() flushing all channels before returning.
1300 Also fixed some documentation typos.
1302 Affected files are lib/silcutil/silclog.[ch].
1304 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1306 * Fixed the server to check correctly the amount of connections
1307 from single host, by checking also the type of the connection.
1308 Fixed also the comparison of number of connections and number
1309 of allowed connections. Affected files are silcd/server.c,
1312 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1314 * Fixed the USERS command reply to save the user's mode on the
1315 channel as well. Fixed JOIN command reply to check whether a
1316 client is on channel already and not join it twice. Affected
1317 file lib/silcclient/command_reply.c.
1319 * Added new file silc-expandos.c into irssi/silc/core/ to return
1320 various stuff for various signal for the statusbar etc. updating.
1321 Now Irssi SILC client prints channel user modes etc. on the
1324 * The user mode (like server/router operator changes) is now shown
1325 on the Irssi SILC client's statusbar. The affected files are
1326 irssi/src/silc/core/client_ops.c, silc-expandos.c.
1328 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1330 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
1331 to SILC_SCHEDULE_[UN]LOCK macros.
1333 * Added more error printing to logs in server code. Affected
1334 files silcd/server.c and silcd/protocol.c.
1336 * Fixed -S option parsing in Irssi SILC Client. Affected file
1337 irssi/src/silc/core/silc-core.c.
1339 * Added silc_buffer_alloc_size function. Affected file is
1340 lib/silcutil/silcbuffer.h.
1342 Tue Mar 5 14:37:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1344 * Changed all silc_[hash|hmac|cipher|pkcs]_default tables to
1345 constants. Affected files in
1346 lib/silccrypt/silcpkcs.[ch], silchash.[ch], silchmac.[ch] and
1349 * Changed the internal SFTP Memory FS table to const. Affected
1350 file lib/silcsftp/sftp_fs_memory.c.
1352 Sun Mar 3 18:37:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1354 * Fixed the buffer formatting and unformatting routines to
1355 check the size of 64 bits types with sizeof(). Affected
1356 file is lib/silcutil/silcbuffmt.c.
1358 Mon Feb 25 17:19:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1360 * Removed 0.6.x backwards support.
1362 Sun Feb 24 12:53:25 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1364 * Changed all integer type names:
1365 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
1366 to avoid collisions with other libraries using same type names
1369 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1371 * Added `prefer_ipv6' argument to the functions
1372 silc_net_gethostbyname[_async]. If it is TRUE it will return
1373 IPv6 address over IPv4. If FALSE IPv4 address is returned
1374 even if IPv6 address was found. Affected files
1375 lib/silcutil/silcnet.[ch].
1377 * Added support silc_net_create_connection[_async] to fallback
1378 to IPv4 address if IPv6 address could not be used (like if
1379 it doesn't work on a specific system). Affected file in
1380 lib/silcutil/unix/silcunixnet.c.
1382 Sat Feb 23 15:20:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1384 * Added silc_schedule_reinit function to do the enlarging
1385 of the max tasks handling capabilities of the scheduler.
1386 Affected files lib/silcutil/silcschedule.[ch].
1388 Wed Feb 20 20:41:01 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1390 * Added automatic extern "C" { ... } for C++ compilers so the
1391 application does not need to define them. Affected file
1392 includes/silcincludes.h.
1394 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
1395 old name went against naming convention. Applications now
1396 include "silcclient.h" instead of "clientlibincludes.h".
1397 Removed includes/clientlibincludes.h, it is redundant now.
1399 * Renamed includes/version.h to silcversion.h.
1401 * Added really preliminary support for OS/2 into the util
1402 library. Only thread & mutex API is implemented, others
1403 are still to be implemented. Created the lib/silcutil/os2/
1404 directory. Created also file includes/silcos2.h.
1406 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1408 * Added preliminary BeOS support into the util library.
1409 Created lib/silcutil/beos/, and implemented all the needed
1410 functions to support SILC on BeOS. Created also file
1411 includes/silcbeos.h.
1413 Mon Feb 18 15:49:22 EET 2002 Timo Sirainen <tss@iki.fi>
1415 * Added proper initializations to silc's irssi code, so it's
1416 now possible to load it as module. Affected files
1417 irssi/src/silc/core/silc-core.c,
1418 fe-common/silc/fe-common-silc-core.[ch] and fe-text/silc.c
1420 Sun Feb 17 19:02:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1422 * Merged latest Irssi (0.8.1) from the irssi.org's CVS into
1425 * Fixed the silcdoc document generator to correct generate
1426 docs from all kinds of filenames. Affected files are
1427 util/robodoc/Source/generator.c, scripts/silcdoc/silcdoc
1429 * ROBOdoc documented lib/silcutil/silcmemory.h.
1430 Added also new function silc_memdup.
1432 * Removed lib/silcutil/silcbufutil.h and moved those routines
1433 to the lib/silcutil/silcbuffer.h.
1435 Sun Feb 17 15:52:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1437 * Added `user_count' to the SilcChannelEntry which now tells the
1438 number of users on the channel. The user count is now saved
1439 in normal server of global channels as well. Affected files
1440 silcd/server.c, idlist.h, packet_receive.c and command.c.
1442 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
1443 include file utility functions.
1445 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
1446 instead of calling directly OS routines.
1448 * Fixed NICK change printing in Irssi SILC Client. Fixed
1449 KICKED notify printing in Irssi SILC Client. Affected file
1450 irssi/src/silc/core/client_ops.c.
1452 * Fixed a NICK change bug in client library, to not recreate the
1453 client_entry->channels hash table everytime nick is changed.
1454 Affected file lib/silcclient/client.c.
1456 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1458 * ROBOdoc documented the lib/silcske/silcske.h, and improved
1459 the SKE interface a bit.
1461 * Fixed padding problem in PKCS#1. The padding was not actually
1462 random since the random number generator was used incorrectly.
1463 This security bug affects only when encrypting with PKCS#1, and
1464 it is not currently used at all in SILC. SILC only use signing
1465 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
1467 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1469 * Rewrote the notify handling in Irssi SILC client to not call
1470 the events as signals. Fixes problems with Perl support.
1471 Affected files irssi/src/silc/core/client_ops.c, silc-channels.c.
1473 * Send the auto-nicking NICK command in client library with
1474 little timeout after connecting. The affected file is
1475 lib/silcclient/client.c.
1477 * Added following new config file settings:
1478 channel_rekey_secs, key_exchange_rekey, key_exchange_pfs,
1479 key_exchange_timeout, conn_auth_timeout, connections_max,
1482 Implemented all the new config settings handling in the server.
1484 Optimized the use of SKE Mutual flag usage. Use it only
1485 if connection authentication protocol is not based in public
1488 Renamed all SilcServerConfigSection* to SilcServerConfig*
1489 to have a bit shorter names.
1491 Affected files silcd/serverconfig.[ch], server.[ch], and
1494 Sat Feb 16 02:46:43 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1496 * Cleaned up the listening sockets code, preparing for the rehash
1497 support. Affected file is silcd/server.c.
1499 * Fixed some output messages. Affected files are silcd/silcd.c,
1502 Fri Feb 15 19:10:20 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1504 * Create lib/doc/silcrng_intro.html document as introduction
1505 to SILC RNG. ROBOdoc documented lib/silccrypt/silcrng.h.
1507 Fri Feb 15 13:23:03 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1509 * Fixes to the silcd config template. Affected file is
1510 doc/example_silcd.conf.in.
1512 * Removed type casts from silc_calloc(), conforming to the
1513 CodingStyle. Affected file is lib/silcutil/silcconfig.c.
1515 * Removed param_name member from client, server, and router
1516 section structs, now identifying the param directly.
1518 Added CONFIG_FREE_AUTH macro in config file parsing.
1520 Affected files are silcd/serverconfig.[ch].
1522 Fri Feb 15 12:24:08 EET 2002 Timo Sirainen <tss@iki.fi>
1524 * Fixed command line parameter handling. All SILC initialization
1525 is now done in silc_core_init() which also fixes autoconnecting
1528 Affected files irssi/src/silc/core/silc-core.c,
1529 irssi/src/fe-text/silc.c.
1531 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1533 * Added new configuration options and blocks:
1534 keepalive_secs, reconnect_count, reconnect_interval,
1535 reconnect_interval_max, reconnect_keep_trying and
1536 require_reverser_lookup. Added ConnectionParam block, and
1537 implemented the connection parameters when connecting as
1538 initiator and when accepting connections as responder.
1540 Added CONFIG_IS_DOUBLE macro in config file parsing, to check
1541 whether given configuration value has been given already.
1543 Affected files silcd/serverconfig.[c], server.[c].
1545 * Splitted the doc/example_silcd.conf.in. Separated the crypto
1546 algorithm parts and created new file silcalgs.conf, that
1547 is now included from the example_silcd.conf.in.
1549 * Optimized the silc_server_connect_to_router_second to take
1550 the connection configuration object from the SilcServerConnection
1551 object instead of finding it during the connecting phase.
1552 Added the configuration object to SilcServerConnection struct.
1553 Affected files silcd/server_internal.h, server.c.
1555 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1557 * Add the client on channel after it was resolved at the
1558 channel message receiving, and it was not already on the
1559 channel. Affected file lib/silcclient/client_channel.c.
1561 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1569 * Unified the serverconfig.[ch]'s helper function interface.
1570 Affected file silcd/serverconfig.[ch].
1572 * Removed doc/example_silc.conf.in since it is redundant.
1573 The make install will now install irssi/silc.conf file.
1575 * Added new Passphrase and Publickey authentication methods to
1576 config file, allowing both public key and passphrase based
1577 authentication to be set at the same time.
1579 Added `prefer_passphrase_auth' setting in config file which
1580 can be used to set to prefer passwd auth if both passwd and
1581 public key is set. If not set, public key is preferred.
1582 This has effect only when being initiator (responder will try
1585 Added support for authentication with passphrase and public key
1586 at the same time. The passphrase is tried first always since
1587 it is faster to check.
1589 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
1591 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1593 * Merged the new SILC Config library, with the server parsing
1594 support. Read the header file silcconfig.h or the toolkit
1595 documentation for the news. Affected files are

1617 * Allow zero length channel messages inside the Channel Message
1618 Payload. Affected file lib/silccore/silcchannel.c.
1620 * Fixed scripts/silcdoc/silcdoc to support all kinds of filenames
1621 as header filenames.
1623 * Removed lib/silcclient/README and created HTML file
1624 lib/silcclient/silcclient_using.html, which is now included
1625 as part of Toolkit documentation.
1627 Thu Feb 7 10:12:25 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1629 * Fixed CUMODE_CHANGE notify handling to change the mode of
1630 correct client. Affected file lib/silcclient/client_notify.c.
1632 * Make silc_rng_alloc fail if it cannot allocate the sha1
1633 hash algorithm. Affected file lib/silccrypt/silcrng.c.
1635 Sun Feb 3 17:20:52 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1637 * Fixed the file transfer's key agreement payload to include
1638 zero port also if the hostname is NULL because it could not
1641 Call file transfer monitor callback now also if error occurs
1642 during key agreement protocol.
1644 Changed the silc_client_file_send interface to return the
1645 SilcClientFileError instead of session id. The session ID
1646 is returned into pointer provided as argument.
1648 Check that the file exists locally before sending the
1649 file transfer request at all.
1651 Affected file lib/silcclient/client_ftp.c, silcapi.h.
1653 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer
1654 error than can occur while key agreement protocol. Affected
1655 file lib/silcclient/silcapi.h.
1657 * Fixed the event_mode CMODE handler to not crash when mode
1658 is changed and +k mode is set in the channel. Affected file

1661 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
1662 SILC_LOG_WARNING to give out Warning and not Error. Affected
1663 file lib/silcutil/silclog.c.
1665 * Fixed the channel message payload decryption in the function
1666 silc_channel_message_payload_decrypt to not modify the original
1667 buffer before it is verified that the message decrypted
1668 correctly. Otherwise, next time it is called with correct
1669 channel key it won't encrypt since the payload is corrupted.
1670 Affected file lib/silccore/silcchannel.c.
1672 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1674 * Do not constantly resize the window. A fix patch by cras.

1680 Affected file lib/silcutil/silcnet.c.
1682 Fri Feb 1 22:33:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1684 * Fixed a bug in hash table internal routine for traversing
1685 the table with foreach callback. The current entry may
1686 become invalid in the callback but it was referenced after
1687 the callback returned.
1689 Do not allow auto rehashing of hash table during the
1690 silc_hash_table_foreach operation, for same reasons as it is
1691 not allowed for SilcHashTableList. Affected files are
1692 lib/silcutil/silchashtable.[ch].
1694 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1696 * Defined DLLAPI into silcincludes.h and silcwin32.h for
1697 Win32 DLL. extern's in header files are now declared with
1700 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1702 * Fixed private message handling. It used some old code that
1703 caused the client to crash. Affecte file is
1704 lib/silcclient/client_prvmsg.c.
1706 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1708 * Added function silc_client_add_channel,
1709 silc_client_replace_channel_id, and removed functions
1710 silc_client_new_channel_id and silc_idlist_get_channel_by_id
1711 from client library.
1713 * Added cross reference of the joined channels to the
1714 SilcClientEntry, and changed the SilcChannelEntry's
1715 users list to SilcHashTable. The affected files are
1716 lib/silcclient/idlist.[ch].
1718 * Fixed a bug in hash table tarversing. While the hash table
1719 is traversed with SilcHashTableList the table must not be
1720 rehashed. It is now guaranteed that auto rehashable tables
1721 are not rehashed while tarversing the list. Also defined that
1722 silc_hash_table_rehash must not be called while tarversing
1723 the table. Added function silc_hash_table_list_reset that must
1724 be called after the tarversing is over. The affected files are
1725 lib/silcutil/silchashtable.[ch].
1727 * Changed all hash table traversing to call the new
1728 silc_hash_table_list_reset in server and in client library.
1730 * Added function silc_client_on_channel to return the
1731 SilcChannelUser entry if the specified client entry is joined
1732 on the specified channel. This is exported to application as
1733 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
1735 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1737 * Fixed founder regaining problem with JOIN command on normal
1738 server. The notify for mode change must be sent always and
1739 not only if !cmd->pending. Affected file silcd/command.c.
1741 * Fixed the WHOWAS command's reply sending to support the
1742 lists correctly. Affected file silcd/command.c.
1744 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1746 * When sending JOIN command to router for processing the
1747 sender's old command identifier was not saved back to the
1748 sender's command context, fixed now. The affected file is
1751 * Create the key in JOIN command of the router did not return
1752 the channel key, added check for this. Affected file is
1755 * Fixed a channel ID update bug in JOIN command reply. Do
1756 not directly upgrade the ID but call the function
1757 silc_idlist_replace_channel_id if the ID was changed.
1758 Affected file silcd/command_reply.c.
1760 * Fixed memory leaks from command calling if it would fail.
1761 Affected file silcd/command.c.
1763 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1765 * Applied patches from cras:
1767 Memory leak fixes around libaries, irssi window resize fix,
1768 new silclist.h and silcdlist.h, all extern inline changed to
1771 * Removed dotconf from lib/dotconf, not needed anymore.
1773 * Removed TRQ from lib/trq, not needed anymore.
1775 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
1776 with server connections. Later this will be configurable
1777 in config file after new config file is done. Affected file
1780 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1782 * Fixed a crash in server related to channel announcements.
1783 Affected file silcd/server.c.
1785 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1787 * Fixed memory leaks in silc_server_create_new_channel*
1788 functions. Affected file silcd/server.c.
1790 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
1791 which ID was changed. This way the router will send the
1792 user list for the channel again, and server won't be in
1793 desync in some rare circumstances. Affected file is
1794 silcd/packet_receive.c.
1796 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1798 * Check for NULL socket pointer in the function
1799 silc_server_packet_send_to_channel_real. Affected file

1807 * Fixed some header addition to Toolkit distribution in
1808 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
1810 * Added lib/silcclient/client_ops_example.h as an template
1811 file for application programmers to quickly start using
1812 the SilcClientOperation functions in their application.
1813 Updated the lib/silcclient/README as well to tell about this
1814 nice file made available.
1816 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1818 * Call silc_server_remove_from_channels when removing client
1819 entry when NO_SUCH_CLIENT_ID was received. Affected file
1820 is silcd/command_reply.c.
1822 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1824 * Added server & router operator statistics updating. Affected
1825 file silcd/packet_receive.c and silcd/command.c.
1827 * Fixed the SERVER_SIGNOFF notify handling on normal server
1828 not to save the history information for clients. Same was
1829 fixed earlier in remove_clients_by_server function, but not
1830 here. Affected file silcd/packet_receive.c.
1832 * Raised the default connection-retry count from 4 to 7 in
1833 server. Affected file silcd/server.h.
1835 * Cancel any possible reconnect timeouts when we start the
1836 key exchange. Affected file silcd/server.c.
1838 * Do not reconnect on connection failure when SCONNECT was
1839 given. Affected files silcd/server.[ch].
1841 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1843 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
1845 * Fixed the NICK command to always give the unformatted
1846 nickname to the one giving the NICK command. If unformatted
1847 nickname is cached already it will be formatted and the
1848 local entry will always get the unformatted nickname.
1849 Affected file lib/silcclient/idlist.c.
1851 * Fixed some double frees from client library commands.
1852 Affected file is lib/silcclient/command.c.
1854 * Fixed CUMODE command in server to assure that no one can
1855 change founder's mode than the founder itself, there was a
1856 little bug. Affected file silcd/command.c.
1858 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1860 * Removed the SilcClientCommandDestructor from the client
1861 libary, it is not needed anymore. Affected files are
1862 lib/silcclient/silcapi.h, command[_reply].[ch],
1863 client_notify, idlist.c.
1865 * Fixed GETKEY command to first resolve client, and then
1866 resolve the server only if the client was not found, instead
1867 of resolving both at the same time. Affected file is
1868 lib/silcclient/command.c.
1870 * Added silc_client_start_key_exchange_cb and lookup the
1871 remote hostname and IP address before starting the key
1872 exchange with server. The affected file is
1873 lib/silcclient/client.c.
1875 * The server's public key is now saved using the IP address
1876 of the server and not the servername for the filename.
1877 The hostname public key filename is checked as an fall back
1878 method if the IP address based filename is not found.
1880 Fixed the GETKEY command to save the fetched server key
1881 in correct filename.
1883 Print the remote server's hostname now when new key is
1884 received during connection process. Affected file is
1885 irssi/src/silc/core/client_ops.c.
1887 * Return always our own public key to the client if it asks
1888 for it with GETKEY command. Affected file silcd/command.c.
1890 * Removed the use_auto_addr variable from default config
1891 file since it was in wrong section. Affected file is
1894 * Fixed TOPIC_CHANGE notification to not route it when it
1895 was sent using silc_server_send_notify_to_channel function.
1896 Affected file silcd/command.c.
1898 * Fixed silc_server_send_notify_kicked to send the kicker's
1899 Client ID also, it was missing. Affected files are
1900 silcd/command.c, silcd/packet_send.[ch].
1902 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1904 * Do not save client history information in SERVER_SIGNOFF.
1905 Fixes the bug in normal server that it does not detect
1906 the client becoming valid after the server becomes back
1907 online. Affected file silcd/server_util.c.
1909 * Added `sock_error' field into the SilcSocketConnection
1910 context. When error occurs during socket operation (read
1911 or write) the error is saved. Added also new function
1912 silc_socket_get_error to return human readable socket error
1913 message. Affected files are lib/silcutil/silcsockconn.[ch],
1914 lib/silcutil/unix/silcunixsockconn.c, and
1915 lib/silcutil/win32/silcwin32sockconn.c.
1917 * The server now prints the socket error message in the
1918 signoff for client. Affected file silcd/server.c.
1920 * Fixed the `created' channel information sending from router
1921 to server in JOIN command. Checks now whether the channel
1922 really was created or not and set it according that.
1924 Fixed the JOIN command to use the client entry's current
1925 ID during the joining procedure instead of the one it sent
1926 in the command (it is checked though), since it can change
1927 between the packet processing and command processing, and
1928 would just case unnecessary pain in the client end. Affected
1929 file silcd/command.c.
1931 * Fixed a channel key payload sending to use correct channel
1932 ID when the server was forced to change the channel's ID by
1933 router. Router sent the key payload with the old Channel ID.
1934 Affected file silcd/packet_receive.c.
1936 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1938 * Call silc_server_save_channel_key only if the key payload
1939 was provided in the JOIN command's command reply. Affected
1940 file silcd/command_reply.c.
1942 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1944 * Fixed silc_mp_sizeinbase to return the value correctly with
1945 MPI. Affected file lib/silcmath/mp_mpi.c.
1947 * Fixed the stop_server signal to correctly stop the scheduler
1948 and gracefully stop the server when SIGTERM or SIGINT signals
1949 are received. Affected file silcd/silcd.c.
1951 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1953 * Simple handling of TERM and HUP signals. Also added some log
1954 flushing call around. Affected file is
1957 * Fixed small bugs in silclog.c. Now buffering output will take
1958 effect after 10 seconds since startup: This will ensure that
1959 no important startup messages are lost. Also output redirection
1960 will preserve original format ([Date] [Type] message).
1961 Affected file is lib/silcutil/silclog.c.
1963 * Added two options to the config file, in the logging section:
1964 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1965 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1967 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1969 * Do not print the warning about log files not being initialized
1970 more than once to avoid excess logging. Affected file is
1971 lib/silcutil/silclog.c.
1973 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1974 the SIM copying in make install in Makefile.am.pre.
1976 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1978 * Rewritten silclog APIs. Globally interesting changes follows:
1979 silc_log_set_files() changed to silc_log_set_file().
1980 silc_log_set_callbacks() changed to silc_log_set_callback().
1981 ROBOdoc documented silclog header file.
1982 SilcLogCb now returns bool to wether inihibit the default
1983 handler or not (to keep the old behaviour return always TRUE).
1984 The new APIs should also fix the problem of the
1985 silcd_error.log file that was written in the current directory.
1988 Log files streams will remain opened after silc_log_set_file()
1989 call, means less CPU usage notably on high traffic servers.
1990 File streams are now full buffered, and flushed to the disk
1991 every 5 minutes, lesses HD activity and CPU usage.
1992 Messages can be redirected, allowing admins to configure
1993 one single logfile for all server messages.
1994 the silc_log_quick global variable to activate fast-logging.
1995 Affected files lib/silcutil/silclog.[ch]
1997 * Changed some code to conform new silclog APIs. Affected
1998 files are doc/example_silcd.conf.in, silcd/server.c
1999 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
2002 * Fixed a memory leak that could occur in some situations.
2003 Affected file silcd/serverconfig.c.
2005 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2007 * Added the silc_client_del_client to remove the client from
2008 all channels as well. Affected file lib/silcclient/idlist.c.
2010 * Fixed the client library to correctly remove the client
2011 from all channels when the client entry is being destroyed.
2012 Affected file lib/silcclient/client_notify.c, command.c.
2014 * Added auto-nicking support to the client library. If the
2015 applicatio now sets client->nickname it will be sent to the
2016 server after connecting by the library. This way for example
2017 SILCNICK (or IRCNICK) environment variables will have effect
2018 and always change the nickname automatically to whatever
2019 it is wanted. Affected file lib/silcclient/client.[ch].
2021 * Renamed silc_server_command_bad_chars to the
2022 silc_server_name_bad_chars and moved it to the
2023 silcd/server_util.[ch]. Added also new function
2024 silc_server_name_modify_bad to return nickname that
2025 includes bad characters as new nickname without those
2026 bad characters. This check and modify is now used in
2027 silc_server_new_client when the username is initially set
2028 as nickname, so it must be checked to be valid nickname.
2029 Affected file silcd/packet_receive.c.
2031 * The nickname length is now taken from the packet for real
2032 and not trusted to strlen() since it clearly can return
2033 wrong length for nickname including bad characters. This
2034 also applies to channel names. Affected file silcd/command.c.
2036 * Removed the lib/silcsilm/modules directory. Modules are now
2037 compiled into the lib/silcsim. Fixed the copying of the
2038 modules to follow symbolic links in Makefile.am.pre.
2040 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2042 * Fixed silc_string_regexify list creation. Fixes bugs with
2043 BAN and INVITE commands in server. The affected file is
2044 lib/silcutil/unix/silcunixutil.c.
2046 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2048 * Removed the command destructor entirely from the server's
2049 command and command reply routines. It is not needed, and
2050 its usage was buggy and caused crashes. Affected files are
2051 silcd/command[_reply].[ch].
2053 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2055 * Cancel protocol and NULL sock->protocol if timeout
2056 occurred during protocol. Affected file silcd/server.c.
2058 * Cancel protocol timeouts always before calling the final
2059 callback, to assure that after final callback is called
2060 no other state will be called for the protocol anymore.
2061 Affected file silcd/protocol.c.
2063 * Print error log if incoming connection configuration could
2064 not be found. Affected file silcd/server.c.
2066 * Fixed JOIN command to correctly save the founder mode
2067 to the client on normal SILC server, when the channel
2068 was created by the router. Affected file silcd/command.c.
2070 * Fixed LIST command (hopefully) to send correct reply
2071 packets. Affected file silcd/command.c.
2073 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2075 * The silc_packet_receive_process now returns FALSE if the
2076 read data was invalid packet, and TRUE if it was ok.
2078 The server now checks that if unauthenticated connection
2079 sends data and its processing fails the server will close
2080 the connection since it could be a malicious flooder.
2082 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
2084 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2086 * Make sure the warning about error opening a log file is
2087 printed only once and not everytime it fails (produces
2088 too much useless log). Affected file lib/silcutil/silclog.c.
2090 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2092 * Made the silc_server_daemonise() function more readable.
2093 Affected file silcd/server.c.
2095 * Pid file is now optional, the user may comment it out from
2096 the config file. Removed define SILC_SERVER_PID_FILE, we
2097 don't need a default any longer. Affected file
2098 configure.in.pre, lib/Makefile.am.pre.
2100 * Make some use of the pid file. The server now dies at startup
2101 if it detects a valid pid file on his path. The server would
2102 die anyway in this circumstance, because of the bind() failure.
2103 Affected file silcd/silcd.c.
2105 * No longer compiling lib/dotconf.
2107 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2109 * Fixed JOIN command parsing not to crash. Affected file
2110 lib/silcclient/command.c.
2112 * Fied the NICK_CHANGE notify to add the new client entry
2113 even it is resolved. This removes an <[unknown]> nick
2114 thingy bug in the client. Affected file is
2115 lib/silcclient/client_notify.c.
2117 * Do not try to allocate 0 bytes (efence does not like it)
2118 in lib/silccore/silccomand.c when encoding payload.
2120 * Do not take IRCNICK as nickname in Irssi SILC client since
2121 it is not possible to set nickname before hand connecting
2122 the server (TODO has an entry about adding auto-nicking
2125 * Changed the silc_server_command_pending to check whether
2126 there already exists an pending entry with the specified
2127 command, command identifier and pending callback. This is
2128 to fix IDENTIFY and WHOIS related crashes that may register
2129 multiple pending commands with same identifier. Affected
2130 file silcd/command.c.
2132 * Fixed the server to reconnect to the router even if it
2133 was already reconnecting and EOF was received. This to
2134 fix a possibility that the server wouldn't ever try to
2135 auto-reconnect to the router. Affected file silcd/server.c.
2137 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2139 * Fixed the server's password authentication to use the
2140 length of the locally saved password, and not the one
2141 sent in the packet. Affected file silcd/protocol.c.
2143 * Fixed same password authentication problem in the
2144 Authentication Payload handling routines in
2145 lib/silccore/silcauth.c.
2147 * Yet another password authentication problem fixed with
2148 channel password handling in silcd/command.c.
2150 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2152 * If first character of string in silc_parse_userfqdn is '@'
2153 then do not parse it. Affected file is
2154 lib/silcutil/silcutil.c.
2156 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2158 * Fixed minor bug in IDENTIFY command reply sending, which
2159 caused various weird problems during JOIN when it was
2160 resolving names for users. Affected file silcd/command.c.
2162 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2164 * Fixed the IDENTIFY command reply sending to chech better valid
2165 clients. It was possible to send incomplete list of replies.
2166 Affected file silcd/command.c.
2168 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2170 * Added silc_client_command[s]_[un]register functions now to
2171 dynamically register the commands in client library. Removed
2172 the static table of commands. This allows the client library
2173 to call commands without causing the application to know about
2174 what commands library has called.
2176 Removed the INFO command reply kludge to detect when the command
2177 was called by library. Now library use its own command reply
2178 function for INFO command.
2180 Added function silc_client_command_call to call a command.
2181 Application can use it to call command, not access the structure
2184 Now all commands that are sent by the client library (not
2185 explicitly sent by application) use own command reply functions.
2187 Affected files around lib/silcclient/ and in
2188 irssi/src/silc/core/.
2190 * Fixed the WHOIS command reply sending to chech better valid
2191 clients. It was possible to send incomplete list of replies.
2193 Fixed the WHOIS and IDENTIFY to send the request to router
2194 if normal server did not do it and did not find any results.
2196 Affected file silcd/command.c.
2198 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2200 * Moved the internal data from SilcClient context into its
2201 own file, not accesible to application. Affected files
2202 lib/silcclient/client.h and lib/silcclient/client_internal.h,
2203 and other files in client library.
2205 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2207 * Added doc/examples installation target in Makefile.am.pre.
2210 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2212 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
2213 commands the found client entry will be removed from the
2214 cache, after notifying application about the error. Affected
2215 file lib/silcclient/command_reply.c.
2217 * Changed the /MSG to check for exact nickname user gave, and
2218 not let `nick' match `nick@host' if it is only one found. Now,
2219 user must type the exact nickname (like nick@host2) even if
2220 there are no more than one same nicks found. This is to avoid
2221 a possibility of sending nickname to wrong nickname since
2222 `nick' could match `nick@host'. Affected file is
2223 irssi/src/core/silc-servers.c.
2225 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2227 * Do not print "you are now server operator" or similar when
2228 giving /away command. Affected files are
2229 irssi/src/silc/core/client_ops.c, silc-servers.h.
2231 * Made the silc_server_command_pending_error_check to send
2232 the same command reply payload it received back to the
2233 original sender of the command. This way all arguments
2234 that was received by the server will be received by the
2235 client too. Affected file silcd/command.c.
2237 * Added the silc_idcache_add to return the created cache entry
2238 to a pointer. Affected file lib/silccore/silcidcache.[ch].
2240 * Add global clients to expire if they are not on any channel.
2241 This is because normal server will never know if they signoff
2242 if they are not on any channel. The cache expiry will take
2243 case of these entries. This is done by normal servers only.
2244 The affected files are silcd/command_reply.c,
2245 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
2247 * If server receives invalid ID notification for WHOIS or
2248 IDENTIFY and the ID exists in the lists, it is removed.
2249 Affected file silcd/command_reply.c.
2251 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
2252 in client then client entry that it matches is searched and
2253 the nickname is printed on the screen for user. Affected
2254 file irssi/src/silc/core/client_ops.c.
2256 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2258 * Use cache entry expire time in the LIST command reply to
2259 purge old entries from the cache after the LIST command
2260 reply has been received. This way we don't have non-existent
2261 entries in the cache for too long. Affected file is
2262 silcd/command_reply.c.
2264 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2266 * If we are normal server, and we've not resolved client info
2267 in WHOIS or IDENTIFY from router, and it is global client,
2268 we'll check whether it is on some channel. If it is not
2269 then we cannot be sure about its validity and will resolve it
2270 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
2271 file silcd/command.c.
2273 * Search channel by name (if possible) rather than by ID
2274 in IDENTIFY command's command reply. Affected file is
2275 silcd/command_reply.c.
2277 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2279 * Distribute to the channel passphrase in CMODE_CHANGE notify.
2280 Updated specs and implemented it. Affected file silcd/command.c,
2281 silcd/packet_send.c and silcd/packet_receive.c.
2283 * Implemented the <founder auth> payload handling in the JOIN
2284 command. If provided all conditions for channel joining
2285 except requirement to provide correct passphrase can be
2286 overrided by the channel founder. Updated the protocol specs.
2287 Affected file silcd/command.c.
2289 Added support for founder auth in JOIN command in client
2290 library. Fixed the parsing of the JOIN command now to support
2291 all options as they should be. The affected file is
2292 lib/silcclient/command.c.
2294 * Optimized the WHOIS and IDENTIFY commands to send the request
2295 to router only if it includes nicknames or other names. If
2296 they include only IDs then check the local cache first before
2297 routing. Affected file is silcd/command.c.
2299 * Added channels topic announcements. Affected file is
2300 silcd/packet_receive.c and silcd/server.c.
2302 * Fixed the silc_server_send_notify_topic_set to really destine
2303 the packet to channel. Affected file silcd/packet_send.c.
2305 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
2306 library. Affected file lib/silcclient/client_notify.c.
2308 * Added UMODE announcements. Affected file silcd/server.c.
2310 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2312 * Memory leak fixes in:
2314 lib/silcutil/silcsockconn.c
2315 lib/silcske/silcske.c
2316 lib/silcske/groups.c
2318 lib/silccrypt/silcpkcs.c
2319 lib/silccore/silccommand.c
2320 lib/silccore/silcidcache.c
2325 * ROBOdoc documented the lib/silcske/groups.h file and a
2326 bit changed the interface for better.
2328 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2330 * Update the client entry context in the ID cache after
2331 nick change. Affected file lib/silcclient/command.c.
2332 Fixes the CUMODE command when regaining founder privileges,
2333 and a little WHOIS problem.
2335 * Fixed silc_net_gethostbyname to correctly call the
2336 inet_ntop. Affected file lib/silcutil/silcnet.c.
2338 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2340 * Added IPv6 support checking to the configure.in.pre, added
2341 also --enable-ipv6 option to override the check. Affected
2342 file configure.in.pre.
2344 * The silc_thread_create now calls the start function
2345 directly if threads support is not compiled in. Removes
2346 ugly #ifdef's from generic code. Affected files are
2347 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
2349 * Added silc_net_gethostby[name/addr]_async to asynchronously
2350 resolve. Affected files are lib/silcutil/silcnet.[ch].
2352 * Added support for rendering IPv6 based server, client and
2353 channel IDs. Affected file lib/silcutil/silcutil.c.
2355 * Added support for creating IPv6 based server IDs. Affected
2356 file is silcd/serverid.c.
2358 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2360 * Added silc_net_gethostby[addr/name] into the
2361 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
2362 routines. Added silc_net_is_ip[4/6]. Affected file is
2363 lib/silcutil/unix/silcunixnet.c. All routines that take
2364 address as argument now supports both IPv4 and IPv6 addresses.
2366 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2368 * Fixed LIST command reply sending in server. Affected file
2371 * Server now sends the kicker's client ID in the KICK notify
2372 to the kicked client. Affected file silcd/command.c.
2374 * The client library now parses the kickers client ID and
2375 UI displays it. Affected files lib/silcclient/client_notify.c
2376 and irssi/src/silc/core/silc-channels.c, module-formats.c.
2378 * Made all payload parsing function prototypes consistent.
2379 They all take now const unsigned char * and uint32 pair as
2380 the payload data instead of SilcBuffer. Changes all around
2381 the source tree. Other unsigned char* -> const unsigned char*
2382 changes around the tree as well.
2384 * Optimized SFTP client and server packet sending not to
2385 allocate new buffer for each packet but to recycle the
2386 first allocated buffer. Affected files are
2387 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
2389 * Optimized the SFTP client to use SilcList instead of
2390 SilcDList for requests, because it is faster. Affected file
2391 is lib/silcsftp/sftp_client.c.
2393 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
2394 into lib/silccore/silcid.[ch].
2396 Renamed silcpayload.[ch] into silcargument.[ch].
2398 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2400 * If client entry is deleted with active key agreement
2401 session, abort the session.
2403 The silc_client_abort_key_agreement now calls the completion
2404 callback with new SILC_KEY_AGREEMENT_ABORTED status.
2406 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
2409 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2411 * Don't use __restrict in older GCC's. Affected file is
2412 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
2414 * silc_net_localhost now attempts to reverse lookup the
2415 IP/hostname. Affected file lib/silcutil/silcnet.c.
2417 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
2418 command. It can be used to gain founder privileges at
2419 the same time when joining the channel.
2421 Defined that the SILC_NOTIFY_TYPE_KICKED send the
2422 kicker's client ID as well. Updated protocol specs.
2424 Defined that the server must send SILC_COMMAND_IDENTIFY
2425 command reply with error status to client who sent
2426 private message with invalid client ID.
2428 Updated the protocol specification.
2430 * Added silc_server_send_command_reply to send any
2431 command reply. Affected file silcd/packet_send.[ch].
2433 * Added silc_id_payload_encode_data to encode ID payload
2434 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
2436 * The server now send IDENTIFY command reply with error
2437 status if client ID in private message is invalid. Affected
2438 file silcd/packet_receive.c.
2440 * Save the server key file with server's IP address in
2441 the filename instead of hostname. The affected file is
2442 irssi/src/silc/core/client_ops.c.
2444 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2446 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
2449 * Added libtool support for compiling shared objects in
2450 lib/silcsim. Affected file configure.in.pre and
2451 lib/silcsim/Makefile.am. Original patch by cras.
2453 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2455 * Pid file configuration, and server's config file fixes
2456 patch by toma. Updated CREDITS file.
2458 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2460 * Fixed silc_client_channel_message to not try to decrypt
2461 the message twice if it resolved the destination client
2462 information. This could cause of dropping one channel
2463 message. Affected file lib/silcclient/client_channel.c.
2465 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2467 * Added silc_client_run_one into lib/silcclient/silcapi.h and
2468 lib/silcclient/client.c. This function is used when the SILC
2469 Client is run under some other scheduler, or event loop or
2470 main loop. On GUI applications, for example this may be
2471 desired to used to run the client under the GUI application's
2472 main loop. Typically the GUI application would register an
2473 idle task that calls this function multiple times in a second
2474 to quickly process the SILC specific data.
2476 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2478 * Fixed silc_server_drop() for dropping the supplementary
2479 groups as well, this could cause a security hole on some
2482 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2484 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by

2488 to run server on foreground. A patch by debolaz.
2489 Affected files silcd/server.c, silcd/silcd.c.
2491 * Fixed MOTD to return the MOTD file server name. Affected
2492 file silcd/command.c.
2494 * Added INFO command reply handling to the Irssi SILC Client.
2495 Affected file irssi/src/silc/core/client_ops.c.
2497 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2499 * Fixed the silc_idcache_list_* routines to really support
2500 the dynamic list. Fixes a crash. Affected file is
2501 lib/silccore/silcidcache.c.
2503 * Fixed the LIST command reply to really call LIST command's
2504 pending callbacks. Affected file silcd/command_reply.c.
2506 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2508 * Update conn->local_entry->nickname after giving NICK
2509 command. Affected file lib/silcclient/command.c.

2513 * Added the [pid] option to the silcd configuration file
2515 Affected files: serverconfig.[ch] and silcd.c
2517 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2519 * Save fingerprint in WHOIS command reply in server.
2520 Affected file silcd/command_reply.c.
2522 * Fixed NICK commands pending callback registration.
2523 Affected file lib/silcclient/command.c.
2525 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2527 * Use ++server->cmd_ident when sending commands in server,
2528 instead of random number. Affected file silcd/command.c.
2530 * Fixed GETKEY command reply to call actually GETKEY pending
2531 command callbacks. Affected file silcd/command_reply.c.
2533 * A bit stricter check for nicknames. Check for same nickname
2534 in NICK command also. Affected file silcd/command.c.
2536 * Do not call INFO command everytime client ID changes, only
2537 during first connecting. Affected file lib/silcclient/client.c.
2539 * Set the new nickname only after successful command reply for
2540 NICK command is returned by server. Affected file
2541 lib/silcclient/command.c.
2543 * Remove nicknames from nicklist during server_signoff notify.
2544 Should fix /NAMES bit more. The affected file is
2545 irssi/src/silc/core/silc-channels.c.
2547 * Added `fingerprint' field to the SilcIDListData in the
2548 silcd/idlist.h to hold the fingerprint of the client's
2551 Send the fingerprint of the client's public key in WHOIS
2554 Affected files silcd/command.c, and silcd/idlist.[ch].
2556 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
2557 create fingerprint from given data.
2559 * Show the fingerprint of the client's public key in WHOIS.
2560 Affected files irssi/src/module-formats.[ch] and
2561 irssi/src/silc/core/client_ops.c.
2563 * Format the multiple same nicknames also during JOIN and
2564 NICK_CHANGE notifys. Affected file is
2565 lib/silcclient/client_notify.c.
2567 * Do not print error on screen for invalid private message
2568 payload since it can come if someone is sending private
2569 messages with wrong key. Affected file
2570 lib/silccore/silcprivate.c.
2572 * Fixed multiple concurrent /PING crash. Affected file
2573 lib/silcclient/command.c.
2575 * Changed the wrong ID encoding. All IP addresses must be
2576 in MSB first order in encoded format. They were encoded
2577 wrong and was in LSB format. Affected files are
2578 silcd/serverid.c, lib/silcutil/silcutil.c.
2580 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
2582 * Call the `connect' client operation through the scheduler
2583 in case of error. Affected file lib/silcclient/client.c.
2585 * Call the `failure' client operation even if the error
2586 occurred locally during a protocol. Affected file is
2587 lib/silcclient/protocol.c.
2589 * Added support of sending LIST command to router from normal
2590 server. This way normal server can get list of all channels
2591 in the network too. Fixed the channel list sending in the
2592 server too. Affected files are silcd/command.c, and
2593 silcd/command_reply.[ch].
2595 * Added silc_server_update_channels_by_server and
2596 silc_server_remove_channels_by_server. They are used during
2597 disconnection of primary router and in backup router protocol.
2598 Affected file silcd/server_util.[ch], silcd/server.c and
2599 silcd/server_backup.c.
2601 * Fixed channel adding to global list in IDENTIFY command
2602 reply in server. Affected file silcd/command_reply.c.
2604 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2606 * If the incoming packet type is REKEY or REKEY_DONE process
2607 that packet always synchronously. Fixes yet another MAC
2608 failed error on slow (dialup) connections. Affected file
2609 lib/silcclient/client.c and silcd/server.c.
2611 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2613 * Call check_version SKE callback for initiator too. Affected
2614 file lib/silcske/silcske.c.
2616 * Implemented fix for security hole found in the SKE that was
2617 fixed in the specification few days back; the initiator's
2618 public key is now added to the HASH value computation.
2619 Added backwards support for the old way of doing it too, for
2620 old clients and old servers. Affected file is
2621 lib/silcske/silcske.c.
2623 * Enabled mutual authentication by default in SKE. If initiator
2624 is not providing mutual authentication the responder will
2625 force it. This will provide the proof of posession of the
2626 private key for responder. The affected files are
2627 lib/silcclient/protocol.c and silcd/protocol.c.
2629 * Do not cache anymore the server's public key during SKE.
2630 We do mutual authentication so the proof of posession of
2631 private key is done, and if the server is authenticated in
2632 conn auth protocol with public key we must have the public
2633 key already. Affected file silcd/protocol.c.
2635 * Added new global debug variable: silc_debug_hexdump. If
2636 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
2637 file lib/silcutil/silclog.[ch].
2639 * Fixed compilation warning due to char * -> const char *.
2640 Affected files lib/silcutil/silcnet.h, and
2641 lib/silccore/silcauth.[ch].
2643 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2645 * Fixed CMODE command when new channel key was created. If
2646 the creation failed the old key was removed. Next time giving
2647 same command would crash the server since the old key was
2648 freed already. Affected file silcd/command.c.
2650 * Fixed the silc_server_announce_get_channels to not crash
2651 on reconnect. Affected file silcd/server.c.
2653 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2655 * Added silc_log_set_debug_string function to set a regex
2656 string to match for debug output. Only the function names,
2657 or filenames matching the given debug string is actually
2658 printed. This way it is possible to filter out those debug
2659 strings that user is not interested in.
2661 Fixed a bug in silc_string_regexify.
2663 Affected files lib/silcutil/silclog.[ch], and
2664 lib/silcutil/unix/silcunixutil.c.
2666 * Changed the -d options in both server and Irssi SILC client
2667 to take the debug string as argument. Affected files
2668 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
2670 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2672 * Added silc_hash_babbleprint to create a Bubble Babble
2673 Encoded fingerprint. The encoding is developed by Antti
2674 Huima (draft-huima-babble-01.txt), and it creates human
2675 readable strings out of binary data. Affected file
2676 lib/silccrypt/silchash.[ch].
2678 * Print the babble print now in addition of fingerprint as well
2679 in Irssi SILC client. Affected files are
2680 irssi/src/fe-common/silc/module-formats.[ch],
2681 irssi/src/fe-common/silc/core/client_ops.c.
2683 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2685 * Fixed a security problem found in SKE. The initiator's
2686 public key too is now added to the HASH hash value creation
2687 which is signed by the responder to create the SIGN value.
2688 This will prevent anyone in the middle to lie to the responder
2689 about the initiator's public key. If this is done now, the
2690 man in the middle will get caught. Updated the protocol
2693 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2695 * Better installation directory handling. Configure module
2696 paths and other paths automatically to example_silc* files
2697 in doc/. A patch by toma.
2699 * Fixed compiler warning from MPI library, and from SILC RNG.
2702 * Added SILC_SERVER_PID_FILE to define the pid file for server.
2703 It can be configured with ./configure. A patch by toma.
2705 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2707 * Find correct make to use in prepare-clean. A patch by
2708 toma. Affected file prepare-clean.
2710 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
2712 * Added irssi variables use_auto_addr, auto_bind_ip,
2713 auto_bind_port and auto_public_ip.
2715 * Changed the interface for silc_client_send_key_agreement
2716 in lib/silcclient/silcapi.h
2720 irssi/src/silc/core/silc-core.c
2722 lib/silcclient/silcapi.h
2723 irssi/src/silc/core/silc-channels.c
2724 lib/silcclient/client_keyagr.c
2727 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2729 * Added silc_pkcs_public_key_compare to compare two
2730 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
2732 * Check that the client who set the founder mode on the
2733 channel is the same client that is giving the founder
2734 mode to itself. It is done by comparing the saved public
2735 key (it is saved even in the authentication is passphrase).
2736 Affected file silcd/command.c.
2738 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2740 * Do not process packet for disconnected socket connection.
2741 Affected file lib/silccore/silcpacket.c.
2743 * Process the DISCONNECT packet through scheduler in the
2744 client library. Affected file lib/silcclient/client.c.
2746 * Fixed the silc_client_packet_parse to not to increase
2747 the packet sequence number if the conn->sock and the
2748 current socket connection is not same. This can happen
2749 for example during key agreement when the conn includes
2750 multiple socket connections (listeners). Affected file
2751 lib/silcclient/client.c.
2753 * The sender of the file transfer request now provides also
2754 the pointer (listener) for the key exchange protocol. If
2755 the listener cannot be created then it sends empty key
2756 agreement and lets the receiver provide the listener.
2758 Added `local_ip' and `local_port' arguments to the
2759 silc_client_file_send. If they are provided they are used,
2760 if not then it will attempt to find local IP address, if
2761 not found or bind fails then the remote client will provide
2764 Affected files are lib/silcclient/client_ftp.c and
2765 lib/silcclient/silcapi.h.
2767 * Extended the FILE SEND command to support defining the
2768 local IP and port for key exchange listener. They are
2769 optional. Affected file irssi/src/silc/core/silc-servers.c.
2771 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2773 * Defined to WHOIS command reply the sending of fingerprint
2774 of the client's public key (if the proof of posession of the
2775 corresponding private key is verified by the server).
2776 Updated to the protocol specification.
2778 * Added support of receiving the client's public key's
2779 fingerprint in command reply in client library. Affected
2780 file is lib/silcclient/command_reply.c, and
2781 lib/silcclient/idlist.[ch].
2783 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2785 * Do not send over 128 chars long nickname to the server
2786 in NICK command. Affected file lib/silcclient/command.c.
2788 * Do not send over 256 chars long channel names to the server
2789 in JOIN command. Affected file lib/silcclient/command.c.
2791 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2793 * Assure that silc_server_close_connection cannot be called
2794 twice for same socket context. Affected file is
2797 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2799 * Send error message to application if opening file for
2800 writing during file transfer fails. Affected file is
2801 lib/silcclient/client_ftp.c.
2803 Remove all file transfer sessions for a client that we're
2804 removing from ID cache.
2806 Affected file is lib/silcclient/client_ftp.c.
2808 * Fixed silc_net_addr2bin to return correct address. Affected
2809 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2811 * Fixed file transfer session removing on signoff notify.
2812 Affected file irssi/src/silc/core/silc-servers.c.
2814 * Added the SilcClientFileError to be returned in the monitor
2815 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
2816 Affected file lib/silcclient/silcapi.h.
2818 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2820 * Fixed a crash in silc_client_ftp_free_sessions and
2821 silc_client_ftp_session_free_client. Affected file
2822 lib/silcclient/client_ftp.c.
2824 * Added `disabled' field in the SilcChannelEntry in the server
2825 to indicate if the server entry is disabled. Affected file
2826 silcd/idlist.h, silcd/command[_reply].c.
2828 * SILC server adds now /var/run/silcd.pid everytime it is
2829 started. Affected file silcd/silcd.c.
2831 * Added silc_server_packet_send_clients to send a packet to
2832 the provided table of client entries. Affected file
2833 silcd/packet_send.[ch].
2835 * Fixed a crash in client resolving in client_prvmsg.c in
2836 client library. Affected file lib/silcclient/client_prvmsg.c.
2838 * Do not actually remove the client directly from ID cache
2839 during SERVER_SIGNOFF, but invalidate it. This way we
2840 preserve the WHOWAS info for the client. Affected file
2841 silcd/server_util.c.
2843 * Fixed SERVER_SIGNOFF notify handling in the server. The
2844 server is now able to process incoming SERVER_SIGNOFF notify
2845 for a server that it doesn't even know about. It will remove
2846 the clients provided in the notify. Affected file
2847 silcd/packet_receive.c.
2849 * Check for partial packet in data queue after every packet that
2850 was found from the queue. Return and wait for more data if
2851 there is partial data in queue. Affected file is
2852 lib/silccore/silcpacket.c.
2854 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2856 * Added SilcClietFileError enum to indicate error in
2857 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
2858 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
2859 Affected files lib/silcclient/silcapi.h and
2860 lib/silcclient/client_ftp.c.
2862 * Check that newsize in silc_buffer_realloc is larger than
2863 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
2865 * Added better monitor of file transfers. It now monitors
2866 key agreement protocol during the file transfer too. Added
2867 error reporting too. Affected files
2868 irssi/src/silc/core/silc-servers.c,
2869 irssi/src/fe-common/silc/module-formats.[ch].
2871 * Wrote a help file for FILE command.
2873 * Added silc_rng_global_get_byte_fast to get not-so-secure
2874 random data as fast as possible. Random data is read from
2875 /dev/urandom if available and from the SILC RNG if not
2876 available. It is used in padding generation. Affected file
2877 lib/silccrypt/silcrng.[ch].
2879 * All packets in client library are now processed synchronously.
2880 Optimized packet processing a lot. Affected file
2881 lib/silcclient/client.c.
2883 * All server connection packets are processing synchronously
2884 now in server, to optimize packet processing. Affected file
2887 * Include files are installed now only in Toolkit distribution
2888 if make install is given. Affected files: all Makefile.am's.
2890 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2892 * Assure that silc_client_notify_by_server_resolve does not
2893 resolve the client information multiple times. If it cannot
2894 be found by the first it cannot be found at all. Affected
2895 file lib/silcclient/client_notify.c.
2897 * Fixed WHOWAS command reply calling. Affected file
2898 lib/silcclient/command_reply.c.
2900 * Removed all references to silc_idlist_get_client from the
2901 Irssi SILC client since that call is internal call used by
2902 the library. The Irssi SILC client will use now client
2903 retrieval functions found in silcapi.h.
2905 * Fixed a bug in resolving nickname info before sending
2906 private message. It used freed memory. Affected file
2907 irssi/src/silc/core/silc-servers.c.
2909 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2911 * Assure my_channels statistics cannot go negative in server.
2912 Affected files silcd/server.c, silcd/server_util.c.
2914 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2916 * Upgraded dotconf 1.0.2 to 1.0.6 in lib/dotconf.
2918 Tue Oct 23 13:51:19 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2920 * Win32 Toolkit changes. Affected files
2921 win32/silc.dsw, win32/libsilc/libsilc.def,
2922 win32/libsilcclient/libsilc.def,
2923 lib/silcutil/silcutil.c, and
2924 lib/sftp/sftp_fs_memory.c.
2926 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2928 * Added silc_net_localip to return local host's IP address.
2929 Affected file lib/silcutil/silcnet.[ch].
2931 * If key exchange or rekey protocol is active for a connection
2932 parse all packets syncronously since there might be packets
2933 in packet queue that we are not able to process without first
2934 processing packets before them. Affected file silcd/server,
2935 lib/silcclient/client.c.
2937 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2938 whether library should continue processing the packet.
2939 Affected file lib/silccore/silcpacket.h.
2941 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
2942 SilcSFTPMonitorData to SFTP server to monitor various
2943 SFTP client requests. Affected file lib/silcsftp/silcsftp.h,
2944 lib/silcsftp/sftp_server.c.
2946 * Added silc_file_size to return file size. Affected file
2947 lib/silcutil/silcutil.[ch].
2949 * Implemented the file transfer support for the client library.
2950 Added preliminary support for simple client to client one-file
2951 transmission. Affected file lib/silcclient/client_ftp.c,
2952 lib/silccilent/client.[ch].
2954 * Added new local command FILE to the Irssi SILC Client.
2955 It is used to perform the file transfer. It has subcommands
2956 SEND, RECEIVE, SHOW and CLOSE. Affected files
2957 irssi/src/silc/core/client_ops.c,
2958 irssi/src/silc/core/silc-server.[ch].
2960 Mon Oct 22 12:50:08 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2962 * Relay the SILC_PACKET_FTP in the server. Affected files
2963 silcd/server.c and silcd/packet_receive.c.
2965 Sun Oct 21 20:21:02 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2967 * Renamed silc_file_read and silc_file_write to functions
2968 silc_file_readfile and silc_file_writefile. Added function
2969 silc_file_open and silc_file_close. Affected files
2970 lib/silcutil/silcutil.[ch].
2972 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2974 * Resolve the client info when received private message or
2975 channel message for a client which nickname we don't know.
2976 Affected files lib/silcclient/client_prvmsg.c and
2977 lib/silcclient/client_channel.c.
2979 * Do not crash in /KEY if client is not connected. Affected
2980 file irssi/src/silc/core/silc-channels.c.
2982 * Added SilcClientStatus field to the SilcClientEntry in the
2983 lib/silcclient/idlist.h.
2985 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
2986 is incomplete and is being resolved, it won't be resolved
2989 Make sure also that USERS command reply does not resolve
2990 twice information. Affected file is
2991 lib/silcclient/command_reply.c.
2993 Make sure that silc_client_get_clients_by_list does not
2994 resolve twice same information.
2996 * Check for valid client->id in the silc_server_free_client_data.
2997 Affected file silcd/server.c.
2999 * Fixed /GETKEY nick@server not to crash if the server entry
3000 is not found. Affected file lib/silcclient/command.c.
3002 * Fixed the silc_server_check_cmode_rights to check the
3003 requested modes correctly. Affected file silcd/command.c.
3005 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3007 * Better checks for non-printable chars in nick added.
3008 Affected file silcd/command.c.
3010 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3012 * Call the silc_server_udpate_servers_by_server in the
3013 primary router that comes back online in the backup resuming
3014 protocol. Otherwise it routes packets wrong. Affected file
3015 silcd/server_util.[ch], silcd/server_backup.c.
3017 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3019 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
3020 lib/silcutil/silcbuffmt.[ch].
3022 * Redefined the SILC packet header to include the padding
3023 length. Affected file lib/silccore/silcpacket.[ch].
3025 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
3026 length for maximum padding up to 128 bytes). Affected
3027 file lib/silccore/silcpacket.h.
3029 * Removed all backwards support for old 0.5.x MAC thingies.
3030 The SILC packet header change makes it impossible to be
3031 backwards compatible.
3033 * Send the ENDING packet with timeout in the backup resuming
3034 protocol. This is to assure that all routers has connected
3035 to the primary router. Affected file silcd/server_backup.c.
3037 * Changed the RNG to take the first IV from random data. It
3038 used to take it from zero actually. Changed the RNG also
3039 to use /dev/urandom during session. /dev/random is used
3040 in initialization. Affected file lib/silccrypt/silcrng.[ch].
3042 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3044 * Changed the SILC packet header to have the first two bytes
3045 (the packet length) encrypted. Affected files aroung the
3046 code tree, lib/silccore/silcpacket.[ch]. Removed the
3047 SilcPacketCheckDecrypt callback. It is not needed anymore
3048 since the silc_packet_receive_process will determine now
3049 whether the packet is normal or special.
3051 * Implemented the unidirectional MAC keys. Affected files
3052 lib/silcske/silcske.c, silcd/protocol.c and
3053 lib/silcclient/protocol.c.
3055 * Implemented the packet sequence number to the MAC computation.
3056 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
3057 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
3058 lib/silcclient/protocol.c.
3060 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3062 * Allow backup router to announce servers. All servers
3063 announced by backup router are added to the global list
3064 automatically. Update hte server's socket to our primary
3065 router also when backup router announces a server.
3066 Affected file silcd/packet_receive.c.
3068 * Do not update the client->router in the function
3069 silc_server_udpate_clients_by_server if the client is on
3070 global list. We might fail to find any specific server
3071 for locally connected clients and local cell clients. They
3072 should still use the `from' and not `to' as client->router.
3073 This fixes backup router resuming protocol. Affected file
3074 silcd/server_util.c.
3076 * Decrease channel statistics count only if the channel
3077 deletion worked. Affected files are silcd/server.c and
3078 silcd/server_util.c.
3080 * Added silc_server_update_servers_by_server to update origin
3081 of all server entries. Used during backup router protocol.
3082 Affected files silcd/server_util.[ch], silcd/server.c. and
3083 silcd/backup_router.c.
3085 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
3086 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
3087 silc_hmac_get_hash and silc_hmac_get_name. Affected file
3088 lib/silccrypt/silchmac.c.
3090 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3092 * Assure that router cannot reroute the same channel message
3093 to the sender. Affected file silcd/packet_receive.c.
3095 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3097 * Made better checks that the channel message is not sent
3098 to the router it came from. Affected file is
3099 silcd/packet_send.c. Fixed memory leak too.
3101 * Announce informations for incoming router connection, but
3102 only after checking if it is replaced by backup router.
3103 Affected file silcd/packet_receive.c.
3105 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3107 * Fixed the backup resuming protocol to work in multiple
3108 router environment. Affected file silcd/server_backup.c.
3110 * Route packet only to one router in the function
3111 silc_server_packet_send_to_channel. Affected file is
3112 silcd/packet_send.c.
3114 * Fixed silc_server_send_notify_dest to set the broadcast
3115 flag. Fixed the silc_server_send_notify_topic to actually
3116 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
3117 Affected file silcd/packet_send.c.
3119 * Changed the SFTP Filesystem interface. Changed the
3120 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
3121 the filesystem operation function. The SilcSFTPFilesystem
3122 is now a context that is allocated by all filesystem allocation
3123 functions and it already includes the operations structure
3124 and filesystem specific context. It is given as argument
3125 now to the silc_sftp_server_start. This made the interface
3126 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
3127 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
3129 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3131 * Changed the backup router adding and getting interfaces
3132 in the server. The router that will be replaced by the
3133 specified backup router is now sent as argument. Affected
3134 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
3137 * Added silc_net_addr2bin_ne to return the binary form of
3138 the IP address in network byte order. Affected files
3139 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
3141 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3143 * Check for existing server ID in silc_server_new_server
3144 and in silc_server_connect_to_router_final and remove the
3145 old entry if it exists. Affected file silcd/packet_receive.c,
3148 * Send the channel message always to only one router, either
3149 in upstream or downstream. Affected file is
3150 silcd/packet_send.c.
3152 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3154 * Wrote the definition of the backup resuming protocol to the
3155 protocol specification.
3157 * Removed one redundant channel key generation from normal
3158 server during joining procedure. Removed one redundant
3159 channel key sending from server to router during joining
3160 procedure. Affected file silcd/command.c.
3162 * Made minor bugfixes to the backup router resuming protocol.
3163 Affected file silcd/server_backup.c, server.c.
3165 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3167 * Added --disable-asm configuration option. Affected files
3168 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
3171 * Implemented the backup resuming protocol that is used to
3172 resume the primary router position in the cell after the
3173 primary router comes back online. Affected files
3174 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
3175 and silcd/server_util.[ch].
3177 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3179 * Sleep two (2) seconds after sending QUIT command to server.
3180 Affected file lib/silcclient/command.c.
3182 * Assure that if outgoing data buffer is pending do not force
3183 send any data. Affected file silcd/packet_send.c.
3185 * Assure that if outgoing data buffer is pending do not force
3186 send any data. Affected file lib/silcclient/client.c.
3188 * Implemented the backup router support when the primary router
3189 goes down. The servers and routers can now use the backup
3190 router as new primary router without loosing connectivity.
3192 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3194 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
3195 in the server to indicate disabled entry. All data read
3196 from the connection will be ignored and no data is sent
3197 for entry that is disabled. Affected files are
3198 silcd/idlist.h, silcd/server.c.
3200 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3202 * Created SFTP client and server test programs in the
3203 lib/silcsftp/tests directory.
3205 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3207 * Implemented memory filesystem (virtual filesystem) for
3208 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
3211 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3213 * Implemented the SFTP (SSH File Transfer Protocol) to the
3214 lib/silcsftp. It includes SFTP client and SFTP server
3217 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3219 * Moved lib/silccore/silcprotocol.[ch] to the
3220 lib/silcutil library.
3222 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
3223 take variable argument list pointer as argument. Affected
3224 file lib/silcutil/silcbuffmt.[ch].
3226 * Added silc_buffer_set function that is used to set data
3227 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
3228 Affected file lib/silcutil/silcbuffer.h.
3230 * Changed various routines in the core library to use the new
3231 silc_buffer_set instead of allocating new buffer only for
3234 * Added 64-bit value formatting and unformatting support to the
3235 silc_buffer_[un]format routines. Affected file is
3236 lib/silcutil/silcbuffmt.[ch].
3238 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
3239 to includes/bitmove.h.
3241 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3243 * Fixed channel user mode saving in client library. Affected
3244 file lib/silcclient/command[_reply].c.
3246 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3248 * Defined the file transfer to the SILC Protocol. Added
3249 new packet type SILC_PACKET_FTP and defined File Transfer
3250 Payload. The mandatory file transfer protocol is SFTP
3251 (SSH File Transfer Protocol). Affected file in addition
3252 of the internet draft is lib/silccore/silcpacket.h.
3254 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
3255 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
3256 is used as part of backup router protocol when the primary
3257 router of the cell is back online and wishes to resume
3258 the position as primary router.
3260 * Redefined the MAC generation keys in the protocol. The
3261 same key is not used anymore in both direction. Both
3262 direction will now use different keys for sending and
3263 receiving. This fixes a potential security flaw. This
3264 change causes incompatibilities in the protocol.
3266 * Redefined also the MAC computation from the packet.
3267 An packet sequence number is now added to the MAC
3268 computation. This prevents possible replay attacks against
3269 the protocol. This change too causes incompatibilities
3272 Added `sequence' field to the SilcPacketContext to hold
3273 the current sequence number for the packet.
3275 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3277 * Added `created' field to the SilcIDListData in the file
3278 silcd/idlist.h to indicate the time when the entry was
3281 * Added `created' field to the SilcChannelEntry too. Affected
3282 file silcd/idlist.h.
3284 * Added `creation_time' aguments to all the announcement functions
3285 in the server. If it is provided then only the entries that
3286 was created after the provided time frame are actually
3287 announced. Affected file silcd/server.[ch].
3289 * The protocol says that the Channel ID's IP address must be
3290 based on the router's IP address. Added check for this in
3291 the silc_server_new_channel when processing incoming New Channel
3292 Payload. Affected file silcd/packet_receive.c.
3294 * Print out the correct version with --version in SILC client.
3295 Affected file irssi/src/silc/core/silc-core.c.
3297 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3299 * Fixed WHOWAS command to check for completnes of the client
3300 entry always, not just when the command is coming from client.
3301 Affected file silcd/command.c.
3303 * Added new function silc_server_packet_queue_purge to purge the
3304 outgoing data queue to the network. After the function returns
3305 it is guaranteed that the outgoing packet queue is empty.
3306 Affected file silcd/packet_send.[ch].
3308 * Purge the outgoing packet queue in the rekey protocol's final
3309 callback to assure that all rekey packets go to the network
3310 before quitting the protocol. Affected file silcd/server.c.
3312 * Added silc_client_packet_queue_parse as similar function as
3313 in server to the client library. The affected file is
3314 lib/silcclient/client.c.
3316 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3318 * Splitted silcd/server.c and created silcd/server_util.[ch]
3319 for utility functions.
3321 * Added new socket flag SILC_SF_DISABLED to indicate that the
3322 connection is open but nothing can be sent to or received from
3323 the connection. Affected file lib/silcutil/silsockconn.[ch].
3324 The checking for disabled socket is checked in the low level
3325 silc_socket_write and silc_socket_read functions.
3327 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3329 * Allow only nicknames and channel names that fits into the
3330 7-bit unsigned char ASCII set. Affected file silcd/command.c.
3332 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3334 * When processing JOIN command reply in server check that if
3335 the channel exists in our global list we'll move it the local
3336 list. Affected file silcd/command_reply.c.
3338 * Fixed the check whether client is joined on the channel already
3339 in JOIN command. Affected file lib/silcclient/command.c.
3341 * Fixed the JOIN command reply to check whether the channel
3342 already exists. Affected file lib/silcclient/command_reply.c.
3344 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3346 * Added silc_ske_status_string to map the SKE error numbers
3347 to readable strings. The affected files are
3348 lib/silcske/silcske[_status].[ch].
3350 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3352 * Do not show the private channels on the WHOIS channel list
3353 as it is not allowed by the protocol. The affected file is
3356 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3358 * Assure that the packet length digged from the actual packet
3359 is something sensible in the silc_packet_decrypt_rest_special
3360 in lib/silccrypt/silcpacket.c.
3362 * Free and NULL the allocated pointer in silc_hmac_alloc if
3363 the HMAC allocation fails. The affected file is
3364 lib/silccrypt/silchmac.c.
3366 * Print the selected security properties to the log files in
3367 the server. Affected file silcd/protocol.c.
3369 * Add SKE's reference counter even if calling the completion
3370 callback manually. Otherwise it goes negative, although it
3371 does not cause any problems. The affected file is
3372 lib/silcske/silcske.c.
3374 * Remove the client entry with short timeout after giving the
3375 KILL command. Affected file lib/silcclient/command.c.
3377 * Fixed to send error reply in WHOIS and IDENTIFY commands in
3378 case all found clients are already disconnected (WHOWAS would
3379 found them) in the server. Affected file silcd/command.c.
3381 * Update the last_receive (time of last data received) to be
3382 updated only when received private or channel message so that
3383 the idle time showed in WHOIS makes more sense.
3385 * Added boolean field `valid' in to the SilcClientEntry in the
3386 client library to indicate whether the entry is valid or not.
3387 This fixes the nickname change bug on channel when changing
3388 the nickname to be same than the old (like nick to Nick) the
3389 nickname formatter doesn't set the new nick anymore to Nick@host.
3390 Affected file lib/silcclient/idlist.[ch].
3392 * Now actually fixed the nickname changing on disconnection.
3393 Added new function silc_change_nick to the Irssi SILC Client.
3394 Affected file irssi/src/silc/core/client_ops.c,
3395 irssi/src/silc/core/silc-nicklist.[ch].
3397 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3399 * Check that the public key exists in the GETKEY command before
3400 trying to encode it. Affected file silcd/command.c.
3402 * Print some notifications on received public keys with GETKEY
3403 command in the Irssi SILC Client. Affected files are
3404 irssi/src/fe-common/silc/module-formats.[ch],
3405 irssi/src/silc/core/client_ops.c.
3407 * Use IDENTIFY command to resolve the server information in the
3408 GETKEY command instead of INFO command. Affected file
3409 lib/silcclient/command.c.
3411 * All command reply functions in the client library now calls
3412 the pending command reply callbacks even if an error has
3413 occurred. The server has done this a long time and now it was
3414 time to move the client library to this as well. Now all
3415 errors can be delivered back to the pending command reply
3416 callbacks if necessary. Affected files are
3417 lib/silcclient/command[_reply].[ch].
3419 * Change the nickname on disconnection back to the username
3420 because in reconnect the server will enforce it to it anyway.
3421 Affected file irssi/src/silc/core/silc-servers.c.
3423 * Fixed a config file parsing bug in the Irssi SILC client.
3424 Affected file irssi/src/silc/core/clientconfig.c.
3426 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3428 * When printing the channel mode on JOIN, verify that the
3429 channel key and channel's HMAC are valid. Affected file
3430 irssi/src/silc/core/client_ops.c.
3432 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3434 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
3435 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
3436 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
3438 * Removed channel key rekey task deleting from the function
3439 silc_server_save_channel_key. Affected file silcd/server.c.
3440 Added explicit timeout task context instead that is used to
3441 delete the task if we are registering a new task before the
3442 new task has elapsed.
3444 * When channel key rekey occurs the client library now saves
3445 the old channel key for a short period of time (10 seconds) and
3446 is able to use it in case some is still sending channel
3447 messages encrypted with the old key after the rekey. Affected
3448 file lib/silcclient/[idlist.h|client_channel.c].
3450 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3452 * Added check to the silc_server_new_id_real to not accept
3453 new ID if it is the sender's own ID. Affected file is
3454 silcd/packet_receive.c.
3456 * Assure that we do not announce ourself or the one we've
3457 sending our announcements when we're router and are announcing
3458 servers to our primary router. Affected file silcd/server.c.
3460 * Fixed silc_server_command_identify_check_client to assemble
3461 correct WHOIS packet. It send corrupted WHOIS packet and
3462 caused problem with router to router connections. Affected
3463 file silcd/command.c.
3465 Fixed also silc_server_command_whois_check the same way
3466 as for the IDENTIFY command.
3468 * Added new SilcIDListStatus to the server in the SilcIDListData
3469 structure. The status now includes the current status of
3470 the entry (like registered, resolved etc.). Affected file
3471 silcd/idlist.[ch]. Defined a bunch of different status types
3472 as well. This replaced the old boolean registered field as well.
3474 Added resolve_cmd_ident field to the SilcClientEntry structure
3475 too so that if the entry is for example being resolved so
3476 another command may attach to the same pending command reply
3477 without requiring to resolve the same entry again. This concept
3478 should optimize the WHOIS and the IDENTIFY resolving under
3479 heavy load by taking away unnecessary resolving for entries
3480 that are being resolved already.
3482 Added support for adding multiple pending commands for one
3483 command idenfier. Affected file silcd/command[_reply].[ch].
3485 * Fixed WHOIS and IDENTIFY save to remove the cache entry
3486 before deleting the data. Otherwise the hash table will have
3487 freed data in comparison functions. Affected file is
3488 silcd/command_reply.c.
3490 * Fixed silc_idlist_replace_client_id to add the new entry to
3491 the cache with NULL nickname. Otherwise there will be invalid
3492 memory as the nickname after the nickname is freed. Affected
3493 file silcd/packet_receive.c.
3495 * Fixed the silc_idlist_get_clients_by_hash. The entries was
3496 saved into wrong slots because the previous number of entries
3497 was not taken into account. Affected file silcd/idlist.c.
3498 Fixed same thing in silc_idlist_get_clients_by_nickname too.
3500 * If we are router and we receive JOIN notify to a channel that
3501 does not have any users then notified client is marked as the
3502 channel founder, as it is it. The affected file is
3503 silcd/packet_receive.c
3505 * Added to the extended hash table API's table_del_*ext functions
3506 the destructor as argument too, so that the caller can decide
3507 which destructor to use or whether to use destructor at all.
3508 Affected file lib/silcutil/silchashtable.[ch].
3510 * Fixed ID Cache purging. It actually deleted the entries from
3511 the hash table after the data was freed. The hash table ended
3512 up comparing freed memory. The affected file is
3513 lib/silccore/silcidcache.c.
3515 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3517 * Fixed Irssi SILC client's KILL command's HELP syntax.
3519 * The USERS command now resolves the detailed user information
3520 if the userinfo field is missing. Affected file is
3521 lib/silcclient/command_reply.c.
3523 * Do not print error in silc_file_read if the read file does
3524 not exist. Just silently return NULL. Affected file is
3525 lib/silcutil/silcutil.c.
3527 * Fixed the silc_log_output to not wine about NULL filename
3528 and to not create some bogus " " filename. Affected file is
3529 lib/silcutil/silclog.c.
3531 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3533 * Fixed various printing bugs on the user interface in the
3534 Irssi SILC Client. Minor changes that were forgotten from
3537 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3539 * Fixed the configure.in.pre and the compilation and distribution
3540 environment to support the new autoconf 2.52. That version is
3541 now required to compile the CVS trunk.
3543 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3545 * Renamed function silc_parse_nickname to silc_parse_userfqdn
3546 to generally parse user@fqdn format strings. Affected file
3547 lib/silcutil/silcutil.c.
3549 * Added nickname_format and nickname_force_format fields to the
3550 SilcClientParams structure. The first one defines the format
3551 for the nicknames that the library will enforce if the receives
3552 multiple same nicknames. The second one is boolean value and
3553 can be used to force the library to always enforce the format
3554 to the nicknames regardles whether there are multiple nicknames
3555 or not. This configurable formatting was employed to flexibly
3556 support accessing multiple nicknames from the user interface.
3557 The userinterface can now set the nicknames to what ever format
3558 they prefer. Affected file lib/silcclient/silcapi.h.
3560 Added function silc_client_nickname_format to the file
3561 lib/silcclient/idlist.c. It performs the nickname formatting.
3563 Added new field `hostname´ to the SilcClientEntry context.
3564 It holds the hostname of the client. Affected file is
3565 lib/silcclient/idlist.h.
3567 * Irssi SILC Client sets the nicknames in nick@hostn format.
3568 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
3569 irssi/src/silc/core/silc-core.c.
3571 The WHOIS printing now also shows both the real nickname and
3572 the formatted nickname so that user knows how to access the
3573 user if there are multiple same nicknames cached. Affected
3574 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
3575 printing formatting too to take the hostname now as a separate
3576 argument. The Affected file is
3577 irssi/src/fe-common/silc/modules-formats.[ch].
3579 * Changed the silc_client_get_clients_local to accept the formatted
3580 nickname as argument. It accepts the real nickname too but the
3581 formatted nickname can be used to find the true entry from
3582 multiple entries. Affected file lib/silcclient/silcapi.h and
3583 lib/silcclient/idlist.c.
3585 * Added nickname_format_parse field to the SilcClientParams.
3586 It is a callback function provided by the application to parse
3587 the nickname out of the formatted nickname string. The library
3588 calls it to get the nickname from the formatted string. Since
3589 the application generally knows better the format of the nickname
3590 string it parses it instead of the library, even though library
3591 encodes the formatted string. If the callback function is not
3592 provided then the library will use the string as is. The
3593 affected file is lib/silcclient/silcapi.h.
3595 * All the nickname strings passed to the client library in
3596 commands are now expected to be formatted nickname strings.
3597 If the command does not support the formatted nickname string
3598 it will assume that the sent string is the actual nickname.
3599 Affected file lib/silcclient/command.c.
3601 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3603 * Added public key authentication support to OPER and SILCOPER
3604 commands in the client library. Affected file is
3605 lib/silcclient/command.c.
3607 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3609 * Changed the get_auth_methdod client operation to be asynchronous.
3610 It can be async if the application resolves the authentication
3611 method from the server during the negotiation. Added new
3612 SilcGetAuthMeth completion callback that the application will
3613 call after resolving the authentication method.
3615 Added function silc_client_request_authentication_method that
3616 the application can use to resolve the authentication method
3617 from the server. Added also SilcConnectionAuthRequest callback
3618 that the library will call after the server has replied. The
3619 application can call this function if it does not know the
3620 current authentication method.
3622 Affected files are lib/silcclient/client.c and
3623 lib/silcclient/silcapi.h.
3625 * The Irssi SILC client now automatically resolves the authentication
3626 method incase any configuration information is not present (and
3627 currently there never is). The affected file is
3628 irssi/src/silc/core/client_ops.c.
3630 * Fixed public key authentication from the client library.
3631 Affected file lib/silcclient/protocol.c. Changed also the
3632 protocol specification about the public key authentication in
3633 the connection authentication protocol. The actual data to be
3634 signed is now computed with a hash function before signing.
3636 * Fixed the public key authentication from the server as well.
3637 Affected file silcd/protocol.c.
3639 * Removed the mlock()'s from the memory allocation routines.
3640 Affected file lib/silcutil/silcmemory.c. The ./configure does
3641 not check anymore for the mlock(). Affected file is
3644 * Fixed USERS command in server to allow the execution of the
3645 command for private and secret channels if the client sending
3646 the command is on the channel. Affected file silcd/command.c.
3648 * Fixed silc_client_get_clients_local to return the clients
3649 count correctly. It could return wrong value. Affected file
3650 lib/silcclient/idlist.c.
3652 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3654 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
3655 types. The assembler optimizations seemed not to like 64-bit
3656 data types. The assmebler optimizations thus are now enabled
3657 also for BSD systems as opposed to only enable them for Linux.
3659 * Do not check for threads at all on BSD systems. Affected
3660 file configure.in.pre.
3662 * Removed -n and -h options from the Irssi SILC Client since
3663 they are not used in silc.
3665 * Fixed the prime generation to assure that the first digit
3666 of the generated random number is not zero since our conversion
3667 routines does not like number strings that starts with zero
3668 digit. If zero digit is seen the random number is regenerated.
3669 This caused some corrupted RSA keys when the zero first digit
3670 was met. Affected file lib/silcmath/silcprimegen.c.
3672 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3674 * Fixed WIN32 configuration in the ./configure script.
3675 Fixed to include xti.h on environments that has it.
3676 Patches by Carsten Ilchmann and andrew.
3678 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3680 * Changed the silc_id_create_client_id to be collision
3681 resistant. It is now assured that there cannot be created
3682 two same client ID's. I suspect that some weird bugs in
3683 the server were actually caused by duplicate Client IDs.
3684 Affected file silcd/serverid.[ch]. A router receiving
3685 new ID now also assures and informs the sending server
3686 if the ID caused collision.
3688 * Changed the silc_id_create_channel_id to also assure that
3689 there are no collisions.
3691 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3693 * Statement about ignoring the Mutual Authentication flag when
3694 performing rekey with PFS was a bit misleading. It is ignored
3695 if it was set in the initial negotiation, it cannot be even
3696 set in the rekey. Fixed in the ke-auth draft. Started the
3697 new versions of the protocol drafts in the doc/.
3699 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3701 * Fixed a bug in silc_client_command_identify_save when saving
3702 new channel information. The channel name was no duplicated
3703 and caused crash on exit. Affected file is
3704 lib/silcclient/command_reply.c.
3706 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3708 * Fixed the getkey command handling in the server. Send just
3709 empty OK reply to the sender if the key could not be fetched
3710 (but everything else was ok, like the key just was not available).
3711 Changed the public key parameter to optional in the protocol
3712 specs so that empty OK reply can be sent. Affected file
3715 Added a message to Irssi SILC client to tell to user if the
3716 server did not return a public key.
3718 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3720 * Fixed a channel key regeneration bug. It registered new
3721 timeout tasks exponentially until all system resources were
3722 used. Affected file silcd/server.c.
3724 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3726 * Added the SILC Document generator to the scripts/silcdoc.
3727 It can be used to generate the Toolkit Reference Manual out
3728 of the source tree. Internally it will also use the RoboDoc
3729 generator now imported in util/robodoc.
3731 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3733 * Added couple of return's in rekey protocol if error orccurred
3734 during the protocol. The execution must be terminated.
3735 Affected file silcd/protocol.c. Also, terminate the protocol
3736 always with timeout.
3738 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3740 * The client's Client ID was created initally from the wrong
3741 nickname (it could have been in format nick@host) in the
3742 silc_server_new_client. Affected file silcd/packet_receive.c
3744 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3746 * Added some SILC_LOG_ERROR's to various error conditions
3747 if client could not be added to ID cache. Affected files
3748 silcd/packet_receive.c and silcd/server.c.
3750 * When client's sock->user_data is freed, NULL also the
3751 client->router and client->connection pointers. Added check
3752 for these pointers being NULL to various places around the
3753 code. Affected file silcd/server.c.
3755 * Added client->data.registered == TRUE checks to various
3756 places around the code to assure that unregistered client's
3757 are not handled when it is not allowed. Affected file
3760 * Added `bool registered' fields to all
3761 silc_idlist_[server|client]_get_* routines to indicate whether
3762 the fetched client needs to be registered or not. Affected
3763 file silcd/idlist.[ch].
3765 * Add your own entry as registered to the ID cache in the
3766 server. Affected file server.c.
3768 * Fixed a bug in silc_server_new_server. The SilcServer was
3769 set as the new server's context instead of SilcServerEntry.
3770 This naturally caused some weird bugs.
3772 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3774 * Do not delete the channel rekey task when adding it
3775 for in silc_server_create_channel_key.
3777 * Changed the silc_server_create_channel_key to return
3778 TRUE or FALSE to indicate the success of the channel key
3781 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3783 * Fixed MSVC++ project files and added missing files to
3784 Makefiles under win32/.
3786 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3788 * Do not add TCP_NODELAY flag if the operating system
3789 does not have it defined. Affected files are
3790 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3792 * Fixed buffer overflow from Irssi SILC Client. Affected
3793 file irssi/src/fe-common/core/themes.c.
3795 * Fixed double free in client library in the file
3796 lib/silcclient/client.c when disconnecting from server.
3798 * Applied double free patch from cras to Irssi SILC client.
3799 Affected files irssi/src/core/[modules/expandos].c
3801 * Fixed the disconnection handling to Irssi SILC Client.
3802 The application must call silc_client_close_connection
3803 in ops->connect client operation in case of failure of
3804 the connection. Affected file is
3805 irssi/src/silc/core/client_ops.c.
3807 * Do not set sock->protocol to NULL in the function
3808 silc_client_close_connection after executing the protocol's
3809 final callback since the sock might not be valid anymore.
3810 Affected file lib/silcclient/client.c.
3812 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3814 * Do not enable SILC_THREADS if the linking with libpthread
3815 did not happen. Affected file configure.in.pre.
3817 * Added notion to protocol specification that server must
3818 verify the sent authentication payload with CMODE when
3819 setting the channel founder key. Implemented it to the
3820 server. Affected file silcd/command.c.
3822 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3824 * Added _EXTRA_DIST SILC distribution variable to the
3825 distributions file. It is used to conditionally add extra
3826 files or directories to the specific distribution. Affected
3827 files ./prepare, Makefile.am.pre and distributions.
3829 Removed the `_' from the start of the distribution names.
3832 * Added README.WIN32 for instructions to compile the Toolkit
3835 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3837 * Fixed a double free in disconnection in the server. Affected
3838 file is silcd/server.c.
3840 * Fixed the lib/silcske/groups.c to work now also with GMP
3841 MP library. The string conversion did not work when using
3842 specific base and the base is indicated in the string as well.
3844 * Created win32/ directory which now includes MSVC++ specific
3845 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3846 It will appear only in the toolkit distribution
3848 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3850 * Changed the key material distribution function in case when
3851 the hash output is too short. The data is now concatenated
3852 a bit differently than it used to. Made the change to the
3853 SKE protocol specification.
3855 * Added better GMP detection to configure.in.pre. A patch
3858 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3860 * Fixed a minor bug in SKE that might cause some problem on
3861 some platforms. Affected file lib/silcske/silcske.c.
3863 * Added the cookie checking for initiator in the SKE. It checks
3864 that the responder returns the sent cookie unmodified. The
3865 affected file is lib/silcske/silcske.c. Added new SKE
3866 error type INVALID_COOKIE that can be sent during the
3867 negotiation. Fixed some memory leaks as well.
3869 * Added the "invalid cookie" error message to Irssi SILC client's
3872 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3874 * Added `task_max' field to the SilcClientParams to indicate
3875 the maximum tasks the scheduler can handle. If set to zero,
3876 default values are used. Affected file lib/silcclient/silcapi.h.
3878 * Fixed memory leaks in silc_client_close_connection. Affected
3879 file lib/silcclient/client.c.
3881 * Added silc_client_del_client_entry to client library to free
3882 all memory of given client entry. Affected file is
3883 lib/silcclient/idlist.[ch].
3885 * Added new functions silc_client_del_channel and
3886 silc_client_del_server to delete channel and server entries.
3887 Affected file lib/silcclient/[silcapi.h/idlist.c].
3889 * Removed silc_client_del_client_by_id from silcapi.h.
3891 * Fixed the INFO command to return the server's own info
3892 correctly when querying by Server ID. Affected file is
3895 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3897 * Removed the non-blocking settings in WIN32 code in the
3898 silc_sock_[read/write] and added SleepEx instead. Affected
3899 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3900 of input data is now checked with FIONREAD and ioctlsocket.
3902 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3904 * Call silc_schedule_task_del_by_context in the
3905 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3906 Affected file lib/silccore/silcprotocol.c.
3908 * Call silc_protocol_cancel for active protocols in the
3909 silc_server_close_connection if the funtion
3910 silc_server_free_sock_user_data has not been called.
3911 Affected file silcd/server.c.
3913 * Generic tasks cannot be deleted using the del_by_fd
3914 task deleting function since generic tasks does not match
3915 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3917 * Added a notion to SILCOPER help file that the SILCOPER works
3918 only on router server, not on normal server.
3920 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3922 * Added for WIN32 support for the new scheduler as well.
3923 Affected file lib/silcutil/win32/silcwin32schedule.c.
3925 * Fixed the SHA1 implementation to work on various platforms.
3927 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3929 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3930 API. It is part of the scheduler now. Everything else is
3931 as previously but some functions has changed their names.
3932 Checkout the lib/silcutil/silcschedule.h for the interface.
3933 Updated all applications to use the new interface. Affected
3934 files are lib/silcutil/silcschedule.[ch].
3936 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3938 * Found a bug in the SKE implementation. The HASH value,
3939 specified by the protocol, was not computed correctly. The
3940 public key of the responder was not added to the computation
3941 even though it is mandatory. Affected file lib/silcske/silcske.c.
3942 This unfortunately causes incompatibilities with older
3943 clients and servers.
3945 * Added WIN32 specific network init and uninit functions:
3946 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3947 the Winsock2. Affected file lib/silcutil/silcnet.h and
3948 lib/silcutil/win32/silcwin32net.c.
3950 * Set the socket always to nonblocking mode on WIN32 after
3951 reading data or writing data. Affected file is
3952 lib/silcutil/win32/silcwin32sockconn.c.
3954 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3956 * Fixed various compilation problems under WIN32. Affected
3957 files lib/silcutil/win32/silcwin32thread.c and
3958 lib/silcutil/win32/silcwin32schedule.c.
3960 * Removed all _internal.h #includes from public header
3961 files. Internal headers must never be included from
3964 Removed also the lib/silcske/payload_internal.h file.
3966 * All include files that may be needed (public and some others
3967 included by the public headers) by application developers are
3968 now copied to the ./includes directory. It does not copy any
3969 internal headers. Affected file Makefile.defines.pre and all
3970 Makefile.am's under lib/ and subdirs.
3972 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3974 * Do not change the ~/.silc directory's permissions automatically.
3975 Affected file irssi/src/silc/core/clientutil.c.
3977 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3979 * Do not cancel the protocol in silc_server_close_connection
3980 it might cause recursion. Now cancelled in the function
3981 silc_server_free_sock_user_data. Affected file silcd/server.c.
3983 * Fixed the silc_server_remove_clients_by_server to regenerate
3984 the channel keys correctly finally. Added also new function
3985 silc_server_remove_clients_channels to actually do it.
3986 Affected file silcd/server.c.
3988 * Fixed the silc_server_new_channel to not crash by giving
3989 wrong router to the new channel. Affected file is
3990 silcd/packet_receive.c.
3992 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3994 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3995 which is given as argument to the silc_client_alloc now.
3996 It can be used to configure the client and set various parameters
3997 that affect the function of the client.
3999 * The USERS command in server did not check whether the channel
4000 is private or secret. Affected file silcd/command.c.
4002 * Added new argument to the USERS command in protocol specification.
4003 The USERS command now can take the channel name as argument
4004 as well. Added support for this in client and server and
4005 updated the protocol specs.
4007 * Completed the GETKEY command in client. It can be now used
4008 to fetch also servers public key not only some clients.
4009 Affected files lib/silcclient/command[_reply].c.
4011 * Added silc_client_get_server to return server entry by the
4012 server name. Affected files lib/silcclient/silcapi.h and
4015 * Redefined the IDENTIFY command in protocol specification to be
4016 more generic. It now can be used to query information about
4017 any entity in the SILC Network, including clients, servers and
4018 channels. The query may be based either the entity's name
4019 or the ID. Added support for this in both client and server.
4021 Affected files silcd/command.c and lib/silcclient/command.c
4022 and command_reply.c.
4024 * Optimized the WHOIS and WHOWAS commands in the server. Removed
4025 the _from_client and _from_server functions. Affected file
4028 * Added silc_client_get_channel_by_id_resolve to the file
4029 lib/silcclient/silcapi.h to resolve channel information by
4030 its ID. Added also silc_client_get_channel_by_id that
4031 does not resolve it from the server.
4033 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4035 * Added SilcServerEntry context into the client library
4036 to represent one server. The INFO command now allocates
4037 these to save the resolved server info. For now on the
4038 client library will also keep information about servers,
4039 connected and resolved with INFO.
4041 The INFO command now allocates the SilcServerEntry context
4042 and saves the server info there. The COMMAND_REPLY in
4043 the INFO now returns the parameters to application in
4044 same order as defined in the protocol specification.
4046 The entries are cached in the client->server_cache.
4048 * The INFO command is now issued after received the Client ID
4049 from the server. Affected file lib/silcclient/client.c.
4051 * The CMODE_CHANGE notify may now return also an SilcServerEntry
4052 to the application as the mode changer might be server.
4053 It is guaranteed that NULL is not returned anymore to the
4054 application. Affected file lib/silcclient/client_notify.c.
4056 The ID Type is now also passed to the application so that
4057 it can check whether the returned entry is SilcClientEntry
4060 Added new function silc_client_get_server_by_id to return
4061 the server entry by ID. Affected files are the
4062 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
4064 * Do not create the channel in the Irssi SILC Client when issuing
4065 the JOIN command but when received the sucessful JOIN command
4066 reply. Otherwise the channel might get created even though we
4067 could not join it. The Affected file is
4068 irssi/src/silc/core/[silc-channels.c/client_ops.c].
4070 * Fixed a channel joining bug in router. The router must also
4071 check the channel modes, invite and ban lists etc. when serving
4072 the JOIN command sent by normal server. Affected file is
4073 silcd/command.c. The router now resolves the client's
4074 information from the server who sent the JOIN command if it
4075 does not know it, and processes the JOIN command only after
4078 * Changed the SilcCommandCb to take new argument; void *context2.
4079 Affected file lib/silccore/silccommand.h
4081 The second argument in the command callbacks in the server now
4082 includes the SilcServerCommandReplyContext if the command was
4083 called as pending command callback from the command reply.
4084 Otherwise it is NULL. When called as pending the status of the
4085 command reply will be checked and if it was erronous the
4086 error will be sent to the original sender of the command.
4087 This way the client always receives the error messages even
4088 though the server was actually the one who received the error
4089 when it resent the command to router, for example. Affected
4090 files silcd/command[_reply].[ch].
4092 * Fixed sending WHOWAS command's error message to client if
4093 the requested client could not be found. It was missing.
4096 * Changed the CMODE and CUMODE commands reply arguments in the
4097 protocol specification. The Channel ID is now sent in both
4098 of the commands to identify the channel. Implemented this
4099 new feature to the client and server. Affected files
4100 lib/silcclient/command_reply.c and silcd/command.c.
4102 * Made better checks for invite and ban lists in the JOIN
4103 command in server. Affected file silcd/command.c.
4105 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4107 * The server now performs the incoming host IP/DNS lookup
4108 using the silc_socket_host_lookup and thus does not block
4109 the server anymore. Affected file silcd/server.c.
4111 * Completed the multi-thread support for SILC Scheduler in
4112 the lib/silcutil/silcschedule.c.
4114 * Fixed the configure.in.pre to detect the pthread correctly
4117 * Fixed a deadlock in silc_task_queue_wakeup in the file
4118 lib/silcutil/silctask.c.
4120 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4122 * Added new function silc_schedule_wakeup that is used in
4123 multi-threaded environment to wakeup the main thread's
4124 schduler. It needs to be used when a thread adds a new task
4125 or removes a task from task queues. After waking up, the
4126 scheduler will detect the task queue changes. If threads
4127 support is not compiled in this function has no effect.
4128 Implemented the wakeup mechanism to both Unix and WIN32
4129 systems. Affected files are lib/silcutil/silcschedule.[ch],
4130 lib/silcutil/unix/silcunixschedule.c and the
4131 lib/silcutil/win32/silcwin32schedule.c.
4133 * Added new function silc_task_queue_wakeup to wakeup the
4134 scheduler by the specified task queue. Affected file
4135 lib/silcutil/silctask.[ch].
4137 * The silc_socket_host_lookup_start now wakes up the scheduler
4138 after adding the timeout task. Affected file is
4139 lib/silcutil/silcsockconn.c.
4141 * The silc_socket_host_lookup is synchronous now if the threads
4142 support is not compiled in. However, the callback is still
4143 called asyncronously through the scheduler, anyway. Affected
4144 file lib/silcutil/silcsockconn.c.
4146 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4148 * Added new function silc_socket_host_lookup to perform
4149 asynchronous IP and FQDN lookups for the socket connection.
4150 Affected files lib/silcutil/silcsockconn.[ch].
4152 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4154 * Added SILC_MUTEX_DEFINE to define the mutex on environments
4155 that may or may not compile the mutex support in.
4157 Changed the silc_mutex_alloc interface. It allocates the
4158 mutex now to the sent pointer and returns TRUE or FALSE.
4160 Affected file lib/silcutil/silcmutex.h.
4162 * Wrote the SILC Task Queue interface to support multi-threads.
4163 Affected file lib/silcutil/silctask.[ch].
4165 * Wrote the SILC Scheduler to support multi-threads. Affected
4166 file lib/silcutil/silcschedule.c.
4168 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4170 * Implemented the SILC Mutex API and SILC Thread API for WIN32
4171 in lib/silcutil/win32/.
4173 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4175 * Defined SILC Mutex API and SILC Thread API and implemented
4176 them for Unix. Affected files are
4177 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
4178 lib/silcutil/unix/silcunixmutex.c and
4179 lib/silcutil/unix/silcunixthread.c.
4181 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4183 * Fixed the silc_server_remove_clients_by_server's channel
4184 key re-generation. The hash table handling was incorrect
4185 and would not work with many channels. Affected file is
4188 * Fixed some memory leaks around the server code.
4190 * Rewrote the silc_server_get_users_on_channel to support IPv6
4191 based Client ID's. Affected file silcd/server.c.
4193 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
4194 specification. However, a separate document must be written
4195 to define the detailed signing procedure and the payload
4196 associated with the flag. Defined the flag to the
4197 lib/silccore/silcchannel.h as well.
4199 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4201 * Changed the dynamic tables to static size tables in the
4202 lib/silccrypt/silchmac.c.
4204 * Removed GCC dependencies from the code. A patch by cras.
4206 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4208 * Do not show the error "Error receiving packet bla bla"
4209 in server if it really was not an error (-2 means that reading
4210 is pending). Affected file silcd/server.c.
4212 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4214 * Fixed a possible crash in silc_server_remove_clients_by_server
4215 in silcd/server.c. Fixed there also some memory leaks.
4217 * Fixed the silc_idlist_replace_client_id. It could replace
4218 wrong key in the hash table. Affected file silcd/idlist.c.
4220 * Do not check whether there are global users on the channel
4221 if the channel->global_users is FALSE. Affected functions
4222 silc_server_remove_from_one_channel and
4223 silc_server_remove_from_channels in silcd/server.c. Also,
4224 do not check if the removed client is local as we can be
4225 sure that global client was not removed from the channel
4226 and checking for global users is not needed.
4228 * The silc_server_remove_clients_by_server now re-generates
4229 the channel keys correctly for those channels that had
4230 clients removed from them. Affected file silcd/server.c.
4232 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4234 * Found the reason of random crashes in the server. We weren't
4235 ignoring the SIGPIPE signal (which can be sent in write())
4236 and it crashed the server. Affected file silcd/silcd.c.
4238 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4240 * Assure that sock->user_data is not NULL in the function
4241 silc_server_packet_send in silcd/packet_send.c.
4243 * Disconnect the remote connection if it could not be added
4244 to any ID lists in the server. The affected file is
4247 * Check in silc_server_packet_send[_real/dest] that the
4248 socket is not disconnecting and ignore the data if it is.
4249 Affected file silcd/packet_send.c.
4251 * Define inline to __inline on native WIN32 compilation.
4252 Affected file includes/silcwin32.h.
4254 * Added some explicit type casts for inline code since MSVC
4255 require them. Affected files lib/silcutil/silcbuffer.h,
4256 lib/trq/silcdlist.h and lib/trq/silclist.h.
4258 * Print warning in log files from now on if the packet
4259 decryption fails. Affected file silcd/server.c.
4261 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4263 * Changed the `say' client operation's interface to accept
4264 new `type' argument to indicate the type of the message sent
4265 by the library. The application may filter the library's
4266 messages according the type. The affected file is the
4267 lib/silcclient/silcapi.h.
4269 * Added two new functions to lib/silcclient/silcapi.h:
4270 silc_client_del_client and silc_client_del_client_by_id.
4271 Affected file lib/silcclient/idlist.c.
4273 * Moved the clientincludes.h from includes/ to silc/ and
4274 serverincludes.h from includes/ to silcd/.
4276 * The modes for the CMODE and CUMODE are now passed as
4277 uint32 for application with COMMAND_REPLY. The affected
4278 file is lib/silcclient/command_reply.c.
4280 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4282 * /WHOIS without arguments shows client's own information.
4283 Affected file lib/silcclient/command.c.
4285 * Changed PING to not accept any arguments. The specs
4286 says that client can ping only the connected server so
4287 requiring an argument is not needed. Affected file is
4288 lib/silcclient/command.c.
4290 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4292 * Fixed a fatal bug in private message sending and reception
4293 encryption and decryption when using private message keys.
4294 The implementation was incorrect and did not follow the
4295 specification. It causd that some of the message were
4296 lost since it did not use the sending and receiving keys
4297 as the protocol suggests. This has been fixed and will cause
4298 incompatibilities with older clients when sending private
4299 message encrypted with private message keys. Affected files
4300 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
4301 and various other in Irssi SILC Client.
4303 Added `responder' boolean argument to the functions
4304 silc_client_add_private_message_key[_ske] to indicate when
4305 the key is added as responder or initiator of the key
4308 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4310 * Removed the silc_ske_check_version function and created
4311 a SilcSKECheckVersion callback. Added also a function
4312 silc_ske_set_callbacks that is now used to set all SKE
4313 callbacks. The callback functions are not given to
4314 the SKE functions anymore, but this function is used to
4317 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
4319 * Added `silc_version' argument to the silc_client_alloc
4320 to define the version of the application for the library.
4321 The library will use the version string to compare it
4322 against the remote host's (usually a server) version
4323 string. Affected file lib/silcclient/silcapi.h
4325 * Added the KE protocol context to Key Agreement context
4326 in client library so that we can abort the SKE if it
4327 is in process when we get timeout. Affected file is
4328 lib/silcclient/client_keyagr.c.
4330 * Do not resolve the client ID forever if it returns in the
4331 first time that such client does not exist. This was done
4332 for example with private message. Affected file is
4333 lib/silcclient/client_prvmsg.c.
4335 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4337 * Do not add regex.h for WIN32. The affected file
4338 includes/silcincludes.h.
4340 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
4341 not work yet 100%. It generates the DLL's automatically
4342 when compiling with --with-win32 under cygwin.
4344 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4346 * lib/contrib/regex.c is not compiled on WIN32.
4348 * Added silc_net_get_socket_opt function to the
4349 lib/silcutil/silcnet.h.
4351 * Added includes/silcwin32.h for WIN32 specific includes
4354 * Do not use ptime structure or any of the posix process
4355 functions on WIN32 in lib/silccrypt/silrng.c.
4357 * Added silc_gettimeofday to provide generic function
4358 for struct timeval on all platforms. Added the function
4359 to lib/silcutil/silcutil.h.
4361 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4363 * Moved the lib/silccore/silcsockconn.[ch] to the utility
4364 library as they clearly belong there. As a plus side we
4365 can make the actual socket connection routines platform
4368 Added also new generic function silc_socket_read and
4369 silc_socket_write (that used to be silc_packet_[read/write].
4370 The implementation of these are platform specific.
4372 * Added WIN32 specific routines of silc_socket_[read/write]
4373 to lib/silcutil/win32/silcwin32sockconn.c.
4375 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4377 * Added preliminary support for native WIN32 compilation under
4378 cygwin (using the -mno-cygwin option for GCC) to the
4379 ./configure.in.pre. The --with-win32 now prepares the
4380 compilation for native WIN32.
4382 * Rewrote the SILC Scheduler interface in the file
4383 lib/silcutil/silcschedule.h. The scheduler is now context
4384 based and does not have anymore any global static scheduler.
4385 Moved the Unix scheduler to the lib/silcutil/unix/ directory
4386 and created lib/silcutil/win32 directory for WIN32 based
4389 * Added Unix specific network routines to the
4390 lib/silcutil/unix/silcunixnet.c and the old
4391 lib/silcutil/silcnet.c includes now only generic routines.
4393 Added WIN32 specific network routines to the
4394 lib/silcutil/win32/silcwin32net.c.
4396 * Added Unix specific utility functions from the
4397 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
4399 * Added WIN32 SILC Scheduler to the file
4400 lib/silcutil/win32/silcwin32schedule.c. The code is of course
4403 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4405 * Do not handle JOIN notify in the server if the target client
4406 is not registered (idata->registered == FALSE). The affected
4407 file is silcd/packet_receive.c.
4409 * Update the nickrec->founder in event_cumode in the Irssi SILC
4410 client. Affected file irssi/src/silc/core/silc-channels.c.
4412 * Fixed the CUMODE_CHANGE notify handling in the server when
4413 server and router are announcing their clients on channels.
4414 Now the mode changes are saved and notified correctly. The
4415 affected file is /silcd/packet_receive.c.
4417 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
4418 They really did not replace the cache entry in the ID Cache.
4419 Now they do that. Affected file silcd/idlist.c.
4421 * Fixed the KICK notify handling in the Irssi SILC client to
4422 update the channel records so that the kicked client does not
4423 appear to be on the channel. The affected file is
4424 irssi/src/silc/core/silc-channels.c.
4426 * Always update the conn->current_channel when executing command
4427 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
4429 * Fixed the KILL notify handling in Irssi SILC client to remove
4430 the killed client on all channels.
4432 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4434 * Fixed the silc_parse_command_line to remove extra spaces
4435 from the start and end of the arguments. Affected file is
4436 lib/silcutil/silcutil.c.
4438 * Cancel and free any active protocol in the function
4439 silc_server_close_connection. Affected file silcd/server.c.
4441 * Cancel and free any active protocol in the function
4442 silc_client_close_connction. Affected file is
4443 lib/silcclient/client.c.
4445 * Do not execute the KILL command for clients that are in
4446 history (ie. they are not in the network). Affected file is
4449 * Fixed KILL notify handling, client does not crash anymore.
4450 Affected file irssi/src/silc/core/silc-channels.c.
4452 * Reduced the default packet buffer size from 2048 to 1024 in
4453 lib/silccore/silcpacket.c.
4455 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
4456 counter to the SKE context that is incresed when the SKE library
4457 performs async operation outside the library. If the outside
4458 process frees the SKE context and FREED status will be set
4459 and the library will detect after the sync operation that the
4460 libary is freed. The affected files are
4461 lib/silcske/silcske[_status].[ch].
4463 * Resolve the client entry information in the function
4464 silc_client_channel_message to assure that NULL pointer is not
4465 passed as client entry to the application. */
4467 * Fixed the task timeout calculation to assure that there is
4468 never negative timeouts. The affected file is
4469 lib/silcutil/silcschedule.c.
4471 * Fixed the channel user mode notification sending in server.
4472 It was sent point-to-point to the router (or to server by router)
4473 but it needs to be destined to a channel. The routines now
4474 supports sending the channel user mode notifys to the channels
4475 when announcing clients and channels. Affected files are
4476 silcd/server.c and silcd/packet_receive.c.
4478 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
4479 It did not actually replace the old channel entry in the cache.
4480 Affected file lib/silcclient/client_notify.c.
4482 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4484 * Fixed a possible crash in silc_packet_send_prepare. It now
4485 assures always that there is enough space in the buffer and
4486 at the tail area of the buffer (for MAC).
4488 Fixed the inbound buffer reallocation in silc_packet_read.
4489 It was old code and did not handle the reallocation correctly.
4492 The affected file is lib/silccore/silcpacket.c.
4494 * Fixed buffer overflow in silc_parse_nickname in the file
4495 lib/silcutil/silcutil.c.
4497 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4499 * make install generates new server keys only if there is not
4502 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4504 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
4505 Added check that if the NOREPLY is set then we will not send
4506 the away message. This avoids infinite loop of away messages
4507 if both clients are away. The affected file is
4508 lib/silcclient/client_prvmsg.c.
4510 * Fixed client crash if /NICK was given without arguments.
4511 Affected file lib/silcclient/command.c.
4513 * Server does not send the invite list in INVITE command back
4514 to the client if the list was not altered. Added this notion
4515 to the protocol spec as well. Affected file silcd/command.c.
4517 Fixed possible crash in INVITE command by checking the
4518 value of silc_server_get_client_route command.
4520 * Fixed the INVITE notify type handling. The arguments are now
4521 taken in correct order and client does not crash. The affected
4522 file is irssi/src/silc/core/silc-channels.c.
4524 Removed the "Inviting xxx to channel" message from the
4525 client library away and let the application handle it.
4526 Affected file lib/silcclient/command.c. Added that message
4527 to Irssi SILC client's message formats.
4529 * Fixed CMODE command crash in client. It now checks the
4530 amount of arguments correctly and does not crash. The affected
4531 file is lib/silcclient/command.c.
4533 * Do not create new channel automatically in silc_channels_join
4534 but check whether the channel by that name already exists.
4535 Affected file irssi/silc/core/silc-channels.c.
4537 * Do not send the SERVER_SIGNOFF to router if the disconnected
4538 entity was the router. Affected file silcd/server.c.
4540 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
4541 SILC client as it was missing from there.
4543 Added the handling of the KICK notify to the Irssi SILC client
4544 as it was missing. Added "you have been kicked" message to
4545 Irssi SILC client's message modules formats.
4547 Added the handing of the KILL notify to the Irssi SILC client
4548 as it was missing. Added the kill message module formats
4551 The affected file is irssi/src/silc/core/silc-channels.c.
4553 * The router did not save the channel mode the server announced.
4554 Affected file silcd/packet_receive.c.
4556 * Fixed a possible crash in INFO command in server. If the
4557 server did not provide the server info it crashed. Affected
4558 file silcd/command.c.
4560 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4562 * Fixed the GETKEY command in the server to check also the
4563 global list. Otherwise the GETKEY would not work correctly
4564 in normal SILC server. Affected file silcd/command.c.
4566 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4568 * Fixed GETKEY crash, it crashed if the command did not succseed.
4570 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4572 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
4573 is now real and not just an macro interface to GMP.
4575 Removed the entire GMP from the source tree and imported new
4576 NSS MPI library instead. Reason for removing GMP is that it is
4577 extremely large and compiles extremely slow. The NSS MPI
4578 is only a few files and compiles in less than 10 seconds.
4579 The speed is also about the same as GMP. The MPI is imported
4580 to lib/silcmath/mpi.
4582 If the system has GMP installed we will still use the GMP.
4583 If it is not then the NSS MPI will be compiled.
4585 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4587 * Merged a long nickname (127 characters long) crash bugfix from
4588 Irssi CVS tree. Affected file irssi/src/core/misc.c.
4590 * Merged a freed memory reference bugfix from Irssi CVS tree.
4591 Affected file irssi/src/core/commands.c.
4593 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4595 * Added the server's public key sving and verification to the
4596 server when performing the SKE. This was missing and the
4597 remote server's (or router's) public key was accepted without
4598 checking whether we have it previously or trust it at all.
4599 Affected file silcd/protocol.c.
4601 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4603 * Check in the silc_server_timeout_remote if protocol is active
4604 and make sure that the protocol's final callback is called so
4605 that all memory if freed. Affected file silcd/server.c.
4607 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4609 * silc_server_whois_send_reply crashed the server if the nickname
4610 was 127 characters long. Affected file silcd/command.c.
4612 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4614 * Added sanity check to the silc_server_new_client. If the hostname
4615 is provided inside username then check that the provided hostname
4616 really is the same as the resolved one. If the hostname was not
4617 resolved then check it from the public key. Affected file is
4618 silcd/packet_receive.c.
4620 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
4621 if the server disconnected us and the connection is not valid
4622 anymore. Affected file irssi/src/silc/core/silc-channels.c.
4624 * Moved the silc_client_[chmode|chumode|chumode_char] away from
4625 the library to the lib/silcutil/silcutil.[ch].
4627 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4629 * Close log file after open. Affected file
4630 lib/silcutil/silclog.c.
4632 * Check whether sock == NULL in silc_client_send_packet and return
4633 if it is. Affected file lib/silcclient/silcclient.c.
4635 * Check rec->entry == NULL in the Irssi SILC Client before
4636 sending the channel message. Affecte file is
4637 irssi/src/silc/core/silc-servers.c.
4639 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4641 * Merged a splitted window bugfix from Irssi CVS tree. The
4642 affected file is irssi/src/fe-text/textbuffer-view.c.
4644 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
4645 It did not print nickname.
4647 * Improved the distributions system a bit.
4649 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4651 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
4652 irssi/src/fe-text/gui-window.c.
4654 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
4655 to in-active server. The affected file is
4656 irssi/src/silc/core/client_ops.c.
4658 * Resolve the client in USERS command reply if the entry does
4659 not have username resolved. The affected file is
4660 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
4661 command to WHOIS command to really resolve stuff. The USERS
4662 is not used any more in any critical section so WHOIS can
4663 be used even though it might be slower than IDENTIFY.
4665 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
4668 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4670 * Changed the protocol API a bit more consistent in the
4671 lib/silccore/silcprotocol.[ch].
4673 * Changed the following headers to ROBODoc format:
4675 lib/silccore/silcpayload.h
4676 lib/silccore/silcprotocol.h
4677 lib/silccore/silcsockconn.h
4679 All core library headers are now formatted.
4681 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4683 * Fixed a bug in Irssi SILC client; do not show that you are
4684 server/router operator if you really are not. Affected file is
4685 irssi/src/silc/core/client_ops.c.
4687 * Renamed silc_command_free_payload to silc_command_payload_free.
4688 Affected file lib/silccore/silccommand.h
4690 * Added silcmath.h to include the prototoypes of various routines
4691 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
4694 * Changed the following headers to ROBODoc format:
4696 lib/silccore/silcchannel.h
4697 lib/silccore/silccommand.h
4698 lib/silccore/silcid.h
4699 lib/silccore/silcidcache.h
4700 lib/silccore/silcmode.h
4701 lib/silccore/silcnotify.h
4702 lib/silccore/silcpacket.h
4703 lib/silcmath/silcmath.h
4705 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4707 * Added checking to the server code not to start the server if
4708 ciphers and stuff are not configured properly. Affected files
4709 silcd/serverconfig.[h] and silcd/server.c.
4711 * Changed the layout of the header files of the public interfaces
4712 in the SILC libraries. The new layout supports ROBODoc
4713 documentation tool (and some others) so that it is easy to create
4714 a library reference manual. All the other headers and source
4715 code must still follow the CodingStyle document. Also source
4716 code must not include these ROBODoc stuffs, only the headers.
4717 Furthermore, all public interface headers must now be named
4718 by using `silc' prefix, example: silcapi.h, silccipher.h.
4719 Some files were renamed due to this. All the other headers
4720 must not be used as public interfaces. I will update the
4721 CodingStyle document later. Changed following headers, so far:
4723 lib/silcclient/silcapi.h
4724 lib/silccore/silcauth.h
4725 lib/silccore/silcprivate.h
4726 lib/silccrypt/silcdh.h
4728 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4732 * Removed silc_client_packet_send_flush from the client library
4733 as it is not needed. Affected file lib/silcclient/client.[ch].
4735 * Added printing of message of unresolved authentication method
4736 to the Irssi SILC client. Added it to the module formats.
4737 Removed the same message from the client library.
4739 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4741 * Added new distribution feature, DISTLABEL. Every distribution
4742 can define own preprocessor label that can be used in the
4743 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
4744 file distributions, acconfig.h.pre and prepare.
4746 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4748 * Added Makefile.defines_int to include the actual definitions
4749 for Makefile.defines.in. Tested the new distribution system,
4750 created distributions and tested installation.
4752 * Added AWAY message printing to the Irssi SILC client. Added
4753 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
4755 * Added SCONNECT command to call the SILC's CONNECT command.
4756 Cannot use CONNECT directly since Irssi uses that internally.
4757 Affected file irssi/src/silc/core/silc-servers.c.
4759 Added ACTION local command. It is same as ME command but takes
4760 the channel as mandatory argument.
4762 Rewrote some of the Irssi's help files to suite for SILC
4765 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4767 * Added Makefile.defines[.in] that should for now on be included
4768 in all Makefile.am file in the source tree. That file includes
4769 all common compilation definitions for SILC source tree.
4771 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4773 * Minor changes to the ./prepare script to change the package
4774 name according the distribution name to the configure.in.
4776 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4778 * Created new distribution system. Added file `distributions'
4779 that defines all the distributions that can be created out of
4780 the SILC source tree. The ./prepare script now reads that
4781 file to determine how to prepare the distributions. The
4782 first argument to the ./prepare is the name of the distribution
4783 and second is the version of the distribution. If given
4784 without arguments it creates the default (toolkit) distribution
4785 with the default version (defined in ./prepare).
4787 All Makefile.am files that are subject to the distributions
4788 are now named as Makefile.am.pre. These are ./Makefile.am
4789 and lib/Makefile.am. Others may be changed later.
4791 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4793 * Added invite list, ban list, some key management and connection
4794 error message printing to module formats in the Irssi SILC client.
4796 * Added new silc_client_set_away_message to set the away message
4797 that is back to the person who sent private message. The
4798 affected file lib/silcclient/silcapi.h and the
4799 lib/silcclient/client_prvmsg.c.
4801 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4803 * Fixed the private message sending in the Irssi SILC client,
4804 added local command KEY to the Irssi SILC client.
4806 Added key management and key agreement message formats to the
4807 irssi/src/fe-common/silc/module-formats.[ch].
4809 Added USERS (alias WHO) printing, server/router operator
4810 indication and LIST command printing to the module formats.
4812 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4814 * Fixed channel joining notify handling, cumode notify handling
4815 from Irssi SILC client.
4817 * Added SILC specific module-formats to the Irssi SILC client so
4818 that SILC specific message hilighting, colors etc is possible.
4819 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4821 Added channel mode, channel user mode, actions, notices,
4822 whois and whowas printing to the the module-formats.c.
4824 * Fixed a bug in channel deletion in the server. The channel
4825 is not left to the cache even if the channel founder auth mode
4826 is set when there are no users anymore on the channel. Affected
4827 file silcd/server.c.
4829 * The silc_net_localhost now resolves the entire hostname including
4830 the domain name. Affected file lib/silcutil/silcnet.c.
4832 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4834 * Changed the ask_passphrase client operation to be ascynchronous.
4835 It has now a completion callback and a context that the
4836 application must call after it has got the passphrase from
4837 the user. Affected files lib/silcclient/silcapi.h,
4838 lib/silcclient/protocol.c, lib/silcclient/command.c and
4841 Added SilcAskPassphrase callback that the application calls
4842 to deliver the passphrase to the library.
4844 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4845 The public key verification and especially a certificate
4846 verification is asynchronous procedure.
4848 Added new SILC_SKE_STATUS_PENDING status to indicate the
4849 request is pending and a callback will be called to finalize
4852 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4853 indicate that remote end did not send its public key (or
4854 certificate), even though we require it. Added check for this
4855 condition in the SKE. This was a security bug, now fixed.
4857 Defined new SilcSKEVerifyCbCompletion callback that is called
4858 when the verification process is completed.
4860 The affected files lib/silcske/silcske_status.h and
4861 lib/silcske/silcske.[ch].
4863 * Changed the verify_public_key client operation to be async
4864 as well. Defined SilcVerifyPublicKey callback that is used to
4865 indicate the success of the public key verification process.
4867 Changed the server and client to use the new async client
4870 * Changed the Irssi SILC client's internal scheduler to be called
4871 twice as many times as it used to be. As a result the client
4872 should be a bit faster now. Affected file is
4873 irssi/src/silc/core/silc-core.c.
4875 * Added support to Irssi SILC client of asynchronous public key
4876 verification and passphrase inquiry. Affected file is
4877 irssi/src/silc/core/silc-core.c.
4879 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4881 * Do not say "You have left channel %s" in client library.
4882 Moved it to the application. Affected files are
4883 lib/silcclient/command.c and silc/client_ops.c.
4885 * Fixed silc_client_get_clients. Command context was not
4886 duplicated and was freed memory in the callback. Affected
4887 file lib/silcclient/idlist.c.
4889 * Do not say "you are now talking..." on JOIN command in the
4890 client library. The appliation must handle it.
4892 * Do not say ".. changed topic to" in command reply in the
4893 client libary. The application must handle it.
4895 * Fixed TOPIC command sending in the client library.
4897 * Fixed a memory leak in silc_client_command_free in the file
4898 lib/silcclient/command.c.
4900 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4902 * Imported a modified version of Irssi client to the source tree.
4903 The Irssi will be used to create a new client called
4904 Irssi SILC. Imported to irssi/.
4906 Added silc_core_init_finish function to the Irssi. Affected
4907 file irssi/configure.in.
4909 A lot changes in the Makefile.ams around the irssi tree.
4911 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4913 * Do not rehash if the new size is same as the old size of the
4914 hash table, in the silc_hash_table_rehash*. The affected file
4915 lib/silcutil/silchashtable.c.
4917 * Replaced hash_table_del_by_context calls from the server
4918 (when channel->user_list and client->channels) to the
4919 hash_table_del as it is sufficient and faster.
4921 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4923 * Added silc_hash_table_list, silc_hash_table_get and the
4924 SilcHashTableList structure to provide an alternative way to
4925 traverse the hash table. The affected files are
4926 lib/silcutil/silchashtable.[ch].
4928 * Changed the server's idlist routines to use the hash table
4929 routines to optimize the code.
4931 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4933 * Replaced the client entry's `channel' list and channel entry's
4934 `user_list' list to hash tables for optimized lookup. Changed
4935 the code to use the hash table interface around the code.
4936 Affected file lib/silcd/idlist.[ch].
4938 * Added `auto_rehash' boolean argument to the function
4939 silc_hash_table_alloc to indicate whether the hash table should
4940 auto-rehash when it thinks is appropriate time. It will
4941 increase the hash table size if the there is twice as much
4942 entries in the table than the size of the table, and will
4943 decrease the size if there are twice as less entries than
4944 the size of the table.
4946 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4948 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4950 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4952 * silc_idcache_purge_by_context deletes the entry now by context
4953 as it is supposed to do. Affected file lib/silccore/idcache.c.
4955 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4956 client is not anymore valid (WHOWAS givens the info) and not
4957 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4959 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4961 * Removed the `data' and `data_len' arguments from the ID Cache
4962 interfaces and added `name' argument. ID Cache does not handle
4963 anymore the binary data only a names associated with given ID.
4965 * When hashing a Client ID with silc_hash_id the entire ID is
4966 not hashed anymore, instead only the hash of the Client ID is
4967 hashed. This way we can access the Client ID from the cache
4968 with Client ID but with the hash of the ID (which is a hash of
4969 the nickname) as well without any difference in performance.
4971 Added also silc_idcache_find_by_id_one_ext to do one on one
4972 searching when we have the actual ID. Added also function
4973 silc_hash_client_id_compare. The affected files are
4974 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4976 * When hashing the name associated with a ID it is always done
4977 in lowercase. This way we can access the cache without worrying
4978 about case-sensitivity, even though, for example nicknames are
4981 * Fixed a bug in server with channel message sending. It put
4982 wrong ID type as destination ID. The affected file
4983 silcd/packet_send.c.
4985 * silc_idcache_del_by_context now deletes from all hash tables
4986 by context. Affected file lib/silccore/idcache.c.
4988 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4990 * Changed the client library to use the new ID Cache interface.
4991 Changes around the source tree.
4993 * Added silc_hash_table_rehash_ext to rehash with specific
4994 hash function. Affected file lib/silcutil/silchashtable.[ch].
4996 * Added silc_hash_string_compare to compare two strings in the
4997 hash table. Affected file lib/silcutil/silcutil.[ch].
4999 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5001 * Added new function silc_idcache_del_by_context into the
5002 lib/silccore/idcache.[ch].
5004 * Changed the server's ID list routines to use the new ID Cache
5005 interface. Changes around the source tree.
5007 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5009 * Added silc_hash_table_del[_by_context]_ext functions in to the
5010 lib/silcutil/silchashtable.[ch].
5012 Removed silc_hash_table_find_all* routines and added new
5013 silc_hash_table_find_foreach to replace them.
5015 Added silc_hash_table_replace_ext function as extended
5016 replacing function. Separated the simple hash table interface
5017 from the extended hash table interface in the file
5018 lib/silcutil/silchashtable.h.
5020 * Fixed minor bugs and changed it to use some of the new
5021 hash table functions in lib/silccore/idcache.c
5023 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5025 * Added new function silc_hash_table_find_all to return all keys
5026 in the hash table by the specified key. As the hash table is
5027 collision resistant it also makes it possible to have several
5028 duplicate keys in the hash table. This function may be used to
5029 find all of the keys from the hash.
5031 Added user_context arguments to the SilcHashFunction,
5032 SilcHashCompare and SilcHashDestructor to deliver user specified
5035 Added new fuctions silc_hash_table_find[_all]_ext to do
5036 extended lookup with specified hash and compare functions and
5037 specified user contexts.
5039 Added new function silc_hash_table_add_ext to add the key
5040 with specified hash function and user context.
5042 Added new function silc_hash_table_foreach to traverse all
5043 entrys in the hash table. Added SilcHashForeach callback
5046 Added new function silc_hash_table_del_by_context to delete
5047 the entry only if the context associated with the key matches.
5049 Affected files are lib/silcutil/silchashtable.[ch].
5051 * Removed silc_hash_[server/client/channel]_id and added just
5052 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
5053 silc_hash_id_compare to compare two ID's using as the hash table
5054 comparison function. Added also silc_hash_data to hash
5055 binary data and silc_hash_data_compare to compare it.
5057 * Removed silc_idlist_find_client_by_hash as it is not needed
5058 anymore. Affected file silcd/idlist.[ch].
5060 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
5061 to use internally the SilcHashTable. The new ID Cache is a lot
5062 faster than the old one. Some of the ID Cache interface was also
5063 rewritten and obsolete and stupid functions were removed.
5065 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5067 * Added entry_count field to the SilcHashTable to keep the number
5068 of the entries in the table. Implemented the function
5069 silc_hash_table_rehash. Added new function
5070 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
5072 Fixed a minor bug in silc_hash_table_free.
5074 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
5075 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
5076 into the lib/silcutil/silcutil.[ch].
5078 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5080 * Implemented a collision resistant hash table into the
5081 lib/silcutil/silchashtable[ch]. See the header and the source
5082 for the SilcHashTable API.
5084 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5086 * Merged dotconf version 1.0.2 into lib/dotconf.
5088 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5090 * Do not compile anything in lib/silcsim/* if the SIM support
5091 is not enabled. The tree should now compile without problems
5094 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5096 * Compiled the SILC under cygwin. Compiled and tested briefly
5097 without problems. More tests needed. The SIMs didn't compile
5100 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
5102 * Fixed possible crash in silc_get_username in the
5103 lib/silcutil/silcutil.c.
5105 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5107 * Fixed a va_arg in silc/client_ops.c.
5109 * Oops, RC5 routines were named AES and caused some problems
5110 when not using SIM's. Affected file lib/silccrypt/rc5.c.
5112 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5114 * Added new SilcIDIP structure into the lib/silccore/id.h and
5115 replaced the old `ip' fields from all SILC ID's to that type.
5116 This is a step towards IPv6 support.
5118 The silc_id_get_len takes now the ID as an extra argument.
5119 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
5120 both IPv4 and IPv6 based ID's.
5122 The affected files are lib/silccore/id.[ch] and other files
5123 around the tree using these routines.
5125 * Removed the ID length arguments in server from various
5126 silc_server_send_notify_* routines -> they are not needed
5129 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5131 * Fixed memory leak in silc_encode_pem_file in the file
5132 lib/silcutil/silcutil.c.
5134 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5136 * Check minor version as well in the SKE. Affected files are
5137 silcd/protocol.c and lib/silcclient/protocol.c.
5139 * Added --identifier option to the server so that an identifier
5140 can be when creating the public key for the server. Affected
5141 file is silcd/silcd.c.
5143 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
5144 lib/silccrypt/silcpkcs.c.
5146 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5148 * Register default ciphers and stuff when using -C option with
5149 the server. Affected file sildc/silcd.c.
5151 * Put back the servers public key filename format, it is better
5152 than the new one. For now, the client keys are saved with the
5153 new filename format. The affected file silc/client_ops.c.
5155 * Implemented the Cipher API for the rest of the ciphers that
5156 did not implement it or implemented it the wrong way.
5158 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5160 * Register default ciphers and stuff when using the -S option
5161 in the client. Affected file silc/silc.c. Same also when
5162 creating new key pair with -C option.
5164 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5166 * Fixed the silc_verify_public_key client operation function to
5167 save the public keys differently. The fingerprint is now
5168 used as filename and not the hostname. This way also the
5169 client keys are saved uniquely and not with hostnames. The
5170 affected file is silc/client_ops.c.
5172 * Trimmed the silc_hash_fingerprint function to remove extra
5173 whitespaces from the end of the fingerprint. The affected
5174 file is lib/silccrypt/silchash.c.
5178 * Added silc_cipher_register_default function to register all
5179 default ciphers. It can be used when configuration files
5180 does not exist and the application does not want any specific
5181 ciphers in any specific order.
5183 The SilcDList is now used as silc_cipher_list dynamically
5184 allocated cipher list. Removed the static list all together
5185 and now all ciphers must be allocated to the dynamic list.
5186 The silc_cipher_alloc routine was changed to check only the
5189 All silc_cipher_* routines that used to return int returns
5192 The affected files lib/silccrypt/silccrypt.[ch].
5194 * The same thing was done to silc_hash_* as for silc_cipher_*
5195 routines. Affected files lib/silccrypt/silchash.[ch].
5197 * The same thing was done to silc_pkcs_* as for silc_cipher_*
5198 routines. Affected files lib/silccrypt/silcpkcs.[ch].
5199 Added also silc_pkcs_[un]register[_default] functions.
5200 Removed the data_context from the PKCS API.
5202 * Added silc_hmac_register_default function to register default
5203 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
5204 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
5205 to unregister all hmacs at once.
5207 * Register the default ciphers, hash functions, PKCSs and HMACs
5208 if client's configuration file does not exist. The affected
5211 * The client did not load the hash functions from the SIM
5212 modules at all. Added support for this. Affected file is
5213 silc/clientconfig.c.
5215 * When decoding public key with silc_pkcs_public_key_decode, check
5216 the supported algorithm only if PKCS are registered. Affected
5217 file lib/silccrypt/silcpkcs.c. The same was done with the
5218 silc_pkcs_private_key_decode.
5220 * Fixed the SILC List routines to keep the list always in order.
5221 It used to change the list's order when traversing the list but
5222 not it preserves the order. Affected file lib/trq/silclist.h.
5224 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5226 * Added the client library to use the SilcSocketConnection's
5227 reference counter (by silc_socket_dup) to prevent the bug that
5228 the socket object may be freed underneath async operation.
5230 * The name resolv library checking fixes in the configure.in.pre.
5233 * Created new version of the protocol drafts for future
5234 development. The -03 drafts are the ones that will be changed
5235 in the trunk now and the -02 will remain as they are.
5237 * Send list of CUMODE notifys to the router when announcing
5238 the channel users to the router. Affected file silcd/server.c.
5239 If the router receiving channel founder CUMODE for a channel
5240 that already has channel founder it will send CUMODE notify
5241 to the sender to remove the channel founder rights from the
5242 announced client. Affected file silcd/packet_receive.c.
5244 * The CUMODE notify may now use Server ID as well as the entity
5245 who changes the mode. Updated protocool specs.
5247 * Updated INSTALL and README files.
5249 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5251 * New web pages in the http://silc.pspt.fi. The pages was
5256 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5258 * Implemented the [DenyConnectin] config section in the server.
5259 Added silc_server_config_denied_conn to check whether incoming
5260 connection is denied. Affected file silcd/serverconfig.[ch].
5262 * Do not check the ports when checking the incoming configuration
5263 data if the port is 0, meaning any. Affected file is
5264 silcd/serverconfig.c.
5266 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5268 * Fixed buffer overflow in silc_string_compare in the file
5269 lib/silcutil/silcutil.c.
5271 * Fixed double free in silc_server_command_leave in the file
5274 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5276 * Fixed the version checking in the server. Affected file is
5279 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5281 * Fixed the configuration data fetching when accepting new
5282 connections in the server. Affected file silcd/server.c.
5284 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5286 * Added `sender_entry' argument to the function
5287 silc_server_packet_relay_to_channel so that we can check
5288 whether some destination actually belongs to the same route
5289 the sender belongs (ie, we must not resend the packet to the
5290 sender). Affected file silcd/packet_send.[ch].
5292 * Added `servername' field to the SilcClientEntry in the server
5293 to hold the name of the server where client is from. Affected
5294 file is silcd/idlist.h.
5296 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5298 * Moved the channel message encrypting in the router betwen
5299 router connections from silc_server_channel_message to the
5300 silc_server_packet_relay_to_channel since we want to check
5301 whether we have anybody channel before encrypting anything.
5302 Affected files silcd/packet_[receive/send].c.
5304 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5306 * Fixed the [AdminConnection] server config section to support
5307 multiple entries. Affected file silcd/serverconfig.c.
5309 * Added support into the server to check the validity of the
5310 incoming connection before executing any KE or authentication
5313 * The connection configuration is now saved to the KE and
5314 connection auth protocol contexts and not fetched anymore in
5315 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
5317 * The local hosts listenning address and port is also resolved
5318 now when starting the server. We want to have the socket object
5319 to include the real address and port for the listener. Added
5320 new function silc_net_check_local_by_sock into the files
5321 lib/silcutil/silcnet.[ch].
5323 * Fixed a broadcast bug in server -> do not broadcast if we
5326 * Fixed a routing bug. Do not route broadcast packets ever.
5327 Broadcast packets must be processed always and not routed since
5328 they may be destined to some other host than yourself and thus
5329 would get routed without no good reason. Affected file is
5332 * Added function silc_server_config_is_primary_route to check
5333 whether primary router connection has been configured (a router
5334 configuration that we are initiating). If there is not, we
5335 will assume that there is only two routers in the SILC network
5336 and we will use the incoming router connection as our primary
5337 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
5339 * Changed the order of the broadcasting. Broadcast _after_ the
5340 packet has been processed not before. Affected file is
5343 * Fixed a [ClientConnection] parsing bug. The port was never
5344 parsed correctly thus resulting to port 0. Affected file
5345 silcd/serverconfig.c.
5347 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
5348 argument and did not set the broadcast packet flag. Affected
5349 file silcd/packet_send.c. Fixed same bug in the function
5350 silc_server_send_notify as well.
5352 * If we receive NEW_ID packet for our own ID in the server, ignore
5355 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5359 * Removed the nickname from the Private Message Payload.
5360 Updated the code and the protocol specs.
5362 * Updated protocol specs for submitting to the IETF.
5364 * Tweaked the Random Number Generator a bit. Affected file
5365 lib/silccrypt/silcrng.c. Exported a new function
5366 silc_rng_[global]_add_noise which can be used to add more
5369 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5371 * Do not parse packets with different timeout when protocol
5372 is active -> may cause problem with rekey. Affected file
5375 * When server receives signoff notify it must not create
5376 new channel key if the client is on any channels since the
5377 sender of the signoff notify will create it.
5379 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5381 * Added printing of error messages during SKE protocol from the
5382 failure packet sent by server during SKE. Affected file
5385 * Removed the client's failure_callback handling with timeout
5386 and handle it immediately when received.
5388 * The SKE library returned wrong type in SUCCESS and FAILURE
5389 packets. They must be 32 bit MSB not 16 bit MSB.
5391 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5393 * Ok, rewrote the logic of the re-key and now it seems to work.
5394 I tested it on high traffic with frequent re-keys without
5395 problems. Added hmac_receive (and renamed hmac to hmac_send)
5396 in SilcClientConnection in lib/silcclient/client.h and
5397 in SilcIDListData in silcd/idlist.h. Also, removed the
5398 SilcPacketParserContext's cipher and hmac fields as they are
5399 not needed anymore and actually caused some problems when
5400 the ciphers and hmac's changed underneath the packet parser.
5402 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5404 * If re-key protocol is active then process the incoming packets
5405 synchronously since we must assure that icoming packets encrypted
5406 with the old key is processed before the new keys is set to
5407 use. This is true other packets than for REKEY packets.
5408 Affected file silcd/server.c. The same was done to client library
5409 as well, affected file lib/silcclient/client.c.
5411 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5413 * Fixed bug in client and server to accept the force send if
5414 the packet is send from silc_[server/client]_packet_process
5415 function. Otherwise the packets are never delivered, oops.
5417 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5419 * Disable force sending of packets when REKEY protocol is active.
5420 We must assure that no packet is sent directly when rekey is
5421 performed. All packets must be sent through packet queue.
5422 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
5423 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
5424 function is silc_[server/client]_packet_send_real to check
5427 * Replaced the SIM paths from example config files to
5428 /usr/local/modules. Also, make install creates now
5429 /usr/local/silc/logs directory to hold all the SILC server
5432 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5434 * Made the configure.in.pre work on Solaris. Patch by salo.
5436 * Made all ciphers compatible with non-x86 machines. Defined
5437 CBC mode macros into lib/silccrypt/ciphers_def.h.
5439 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5441 * Fixed the make install.
5443 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5445 * When MAC computation fails the silc_packet_decrypt returned 0
5446 even though it was supposed to return -1. Fixed this. The
5447 affected file is lib/silccore/silcpacket.c.
5449 * Do not replace the config files in /etc/silc (in make install)
5450 if they already exist. Affected file ./Makefile.am.
5452 * Do not send re-key packets immediately but through packet queue.
5453 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
5455 * Changed silc_net_check_host_by_sock to return FALSE if the
5456 IP/DNS could not be resolved. Though, it returns the IP address
5457 now even if it could not resolve it (but returns also FALSE).
5458 Affected file lib/silcutil/silcnet.[ch].
5460 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5462 * Added silc_pkcs_decode_identifier to decode the public key's
5463 identifier. Affected file lib/silccrypt/silpkcs.[ch].
5464 Added also silc_pkcs_free_identifier. Added also new context
5465 SilcPublicKeyIdentifier.
5467 * Added -S option to the silc client. It is used to dump the
5468 contents of the specified public key file.
5470 * Changed the PKCS api to return the public key length when
5471 setting the public key.
5473 * Fixed a fatal bug in the public and private key file loading.
5474 Affected file lib/silccrypt/silcpkcs.c.
5476 * Execute the packet parsing for client with zero (0) timeout
5477 if the protocol is active. Affected file silcd/server.c.
5479 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5481 * Made the key generation options to the silcd program. Added
5482 -C option, equivalent to client's option.
5484 * Added new [ServerKeys] config section to the server. It
5485 configures the server's public and private key.
5487 * Defined generic Public Key Payload into the protocol
5488 specification to send specific type of public keys and
5491 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
5492 public key or certificate.
5494 * Implemented the GETKEY command to the server and to the
5495 client library and on user interface.
5497 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5499 * Made preliminary `make install' work.
5501 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5503 * Added SilcServerRekey context into silcd/idlist.h.
5505 * Added the PFS support as defined in the specification to the
5506 SKE protocol. Affected files lib/silcske/*.c.
5508 * Added `ske_group' field to the SilcServerRekey context to hold
5509 the number of the SKE group that is used with PFS in re-key.
5510 Affected file silcd/idlist.h.
5512 * Added PFS re-key support to the server. Affected file is
5515 * Added silc_protocol_cancel to cancel execution of the next
5516 state of the protocol. Affected file is
5517 lib/silccore/silcprotocol.[ch].
5519 * Added the re-key support with and without PFS to the client
5520 library. Re-key is performed once in an hour, by default.
5522 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
5523 Added silc_client_rekey_callback and silc_client_rekey_final.
5524 Affected files are lib/silcclient/protocol.[ch] and
5525 lib/silcclient/client.[ch].
5527 * Removed the `hmac_key' and `hmac_key_len' fields from the
5528 SilcClientConnection structure; not needed. Affected file is
5529 lib/silcclient/client.h.
5533 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5535 * Do not ask whether user wants to use the negotiated private key
5536 for private messages, just use it. Affected file is
5537 silc/local_command.c.
5539 * Added `send_enc_key' and `enc_key_len' fields to the
5540 SilcIDListData structure since they are needed in the re-key
5541 phase. Affected file is silcd/idlist.[ch].
5543 * Implemented the simple re-key protocol into the server.
5544 Affected files silcd/server.c and silcd/protocol.[ch]. The
5545 re-key will be performed once in an hour, by default.
5547 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
5548 Added silc_server_rekey, silc_server_rekey_callback and
5549 silc_server_rekey_final.
5551 * Removed Tunneled flag from the protocol. Updated the code
5552 and the specifications.
5554 * Adde `pfs' field to the SilcIDListData to indicate whether
5555 the PFS is to be performed in the re-key. Affected file is
5558 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5560 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
5561 int64 of at least the xintXX size. If void * is less that 4
5562 bytes uint32 * will be used. Defined bool as boolean.
5564 * Changed _ALL_ unsigned long and unsigned int to uint32,
5565 unsgined short to uint16 in the source tree.
5567 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
5568 not handle clients that has entry->data.registered == FALSE.
5569 They are not in the network anymore. Affected file is
5572 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5574 * Implemented the sending of the SERVER_SIGNOFF notify in the
5575 server. Affected file is silcd/server.c.
5577 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
5578 Added also silc_notify_payload_encode_args into the
5579 lib/silccore/silcnotify.[ch].
5581 * Implemented ther SERVER_SIGNOFF notify handling in the server.
5582 Affected file silcd/packet_receive.c.
5584 * Implemented the SERVER_SIGNOFF notify handling in the client
5585 library. Affected file lib/silcclient/client_notify.c. Also,
5586 implemnted the printing of the SERVER_SIGNOFF info to the
5587 application. Affected file silc/client_ops.c.
5589 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
5590 if the deleting was successful. Affected file silcd/idlist.[ch].
5592 * Added support for public key authentication in the connection
5593 authentication protocol in the client library. Affected file
5594 lib/silcclient/protocol.c.
5596 * Changed the server's silc_idlist_get_clients_by_* interface
5597 to support already allocated array so that new entries may be
5598 added to pre-allocated array. Affected file silcd/idlist.[ch].
5599 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
5600 and command replies.
5602 * All command reply functions in the server now calls the
5603 pending command callback even if error occured. This way the
5604 error will be delivered to the client as well. Affected files
5605 silcd/command.c and silcd/command_reply.c.
5607 * Fixed INFO command to return local server's info if no server
5608 was provided. Affected file lib/silcclient/command.c.
5610 * Removed RESTART command for good. Updated the code and the
5613 * Rewrote parts of the task system. It is a bit simpler now.
5614 Removed unsued task priorities. The affected files are
5615 lib/silcutil/silctask.[ch].
5617 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5619 * Moved the USERS printing from the library to the application.
5620 Affected files lib/silcclient/command.c and silc/client_ops.c.
5622 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5626 * Added channel key re-key support. The re-key is perfomed
5627 only by the router and is done once in an hour. Added `rekey'
5628 field to the SilcChannelEntry in the server. Affected files
5629 silcd/server.c and silcd/idlist.h.
5631 * Added silc_task_unregister_by_context into the file
5632 lib/silcutil/silctask.[ch].
5634 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5636 * Added SILC_UMODE_GONE mode to indicate when the client is not
5637 present in the SILC network. Added also support to the local
5638 command AWAY that will set this mode. Added support of showing
5639 "xxx is gone" in WHOIS command. The USERS command shows the
5640 gone status as well.
5642 * Fixed setting server and router operator privileges in the
5643 server's UMODE command. Affected file silcd/command.c.
5645 * Merged the SKE KE1 and KE2 payloads into one payload. The
5646 new KE payload is equivalent to the old KE2 payload.
5648 Cleaned up the SKE Start Payload parsing. It now uses the
5649 simple buffer unformatting to do the parsing. A lot faster
5652 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
5653 to the SKE that is used to indicate whether both of the SKE
5654 parties should perform authentication. By default only the
5655 responder performs authentication. By setting this flag also
5656 the initiator must do authentication. By default it is unset
5657 since in normal SKE case, client to server connection, only
5658 the responder should do authentication. When doing SKE between
5659 two clients both should perform authentication. Updated the
5660 code and the protocol specs.
5662 * A little fix to IDENTIFY command in the server. Search the
5663 client first by hash not nickname. Affected file is
5666 * Fixed the silc_client_close_connection to support closing
5667 the client to client connections wihtout deleting too much
5668 data. Affected file lib/silcclient/client.c.
5670 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
5671 are received if protocol used to be active but is not anymore
5672 the application would crash due to NULL pointer dereference.
5673 Affected files silcd/server.c and lib/silcclient/client.c.
5675 * Added `hash' field to the SilcClientConnection to include
5676 the hash function negotiated in the SKE protocol.
5678 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
5679 to set the channel founder authentication data. A client can
5680 claim the founder rights later by providing the authentication
5681 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
5682 This way the channel founder can regain the channel founder
5683 privileges even it is left the channel. This works only on
5684 local server and the client must be connected to the same
5685 server to be able to regain the founder rights. Updated the
5686 protocol specs accordingly.
5688 Added support to the CMODE command in the client to set the
5689 founder auth data. Read the README to see how to set it.
5691 Added support to the CUMODE command to claim the founder
5692 rights. Read the README to see how to do it.
5694 Added support for the founder authentication to the Channel
5695 Entry in the server. Affected file silcd/idlist.h.
5697 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
5698 server's CMODE command. Affected file silcd/command.c.
5700 * Added the following new functions into lib/silccore/silcauth.[ch]:
5701 silc_auth_get_method and silc_auth_get_data.
5703 * The server now saves the remote hosts public key to the
5704 SilcIDListData pointer. Affected file silcd/protocol.c.
5706 * The normal server now does not remove the channel entry from
5707 the cache if the founder authentication data is set. It used
5708 to remove it if the founder was the last one on the channel on
5709 the server and left the channel. The auth data is saved and
5710 if the channel is re-joined later the old entry is used with
5711 the old auth data. Affected files silcd/command_reply.c and
5714 * Removed the `pkcs' field from the SilcIDListData structure
5715 in the server; it is not used. Affected file silcd/idlist.h.
5717 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5719 * Fixed packet processing on slow links. Partial packets were
5720 never re-processed because the incoming data buffer was cleared
5721 by the application. Application must not directly clear the
5722 sock->inbuf, the packet processing routines handle it. Fixed
5723 this in client library and in server.
5725 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5727 * Fixed the WHOIS and IDENTIFY send reply function to really
5728 check whether to send list or just one entry. Affected file
5731 * Cleaned up the LEAVE command's channel key distribution. The
5732 affected file silcd/command.c.
5734 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
5735 can enforce the channel mode as well. In that case the ID
5736 includes the ID of the server. The code now enforces the
5737 mode change if the router have different mode than the server.
5739 * The notify client operation with CMODE_CHANGE notify can now
5740 return NULL client_entry pointer if the CMODE was not changed
5741 by client. Application must check for this.
5743 * Added <Server ID> argument to INFO command to support server
5744 info fetching by Server ID.
5746 * Added silc_server_announce_get_channel_users to get assembled
5747 packets of channel users of the specified channel. Affected
5748 file silcd/server.[ch].
5750 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
5751 was freed underneath the ID Cache.
5753 * Re-announce clients when the server received CHANNEL_CHANGE
5754 notify from the router. Affected file silcd/packet_send.c.
5756 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5758 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
5759 crashed since it did not handle the fact that there is no cipher
5760 called "3" and didn't check the error condition. Now fixed.
5762 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
5763 flag. It can be used to send message requests.
5765 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5767 * Implemented the RESTART command in the client.
5769 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
5770 notice type messages. Added notice printing to the user
5773 * The channel keys are not re-generated if the channel's mode
5774 is PRIVKEY, ie private key on the channel exists. Affected
5775 files silcd/server.c and silcd/command.c.
5777 * Fixed a little bug in channel message delivery when channel
5778 private keys are set in the server. Affected file is
5779 silcd/packet_send.c.
5781 * Changed the setting on channel->on_channel = TRUE from the
5782 silc_client_save_channel_key to the JOIN command reply. The
5783 key payload is not received if the private channel key is set.
5784 Affected file lib/silcclient/command_reply.c and the
5785 lib/silcclient/client_channel.c.
5787 * When the CMODE_CHANGE notify is sent and the channel private
5788 key mode is removed the channel key must be re-generated in
5789 other cells as well. Added this support for the router in the
5790 silcd/packet_receive.c.
5792 * Added new local command NOTICE to send notice message on
5793 channel. Affected file silc/local_command.[ch].
5795 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5797 * Added new local command ME to the client. It is used to send
5798 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
5799 some action. Affected file silc/local_command.[ch].
5801 * Changed channel_message and private_message client operations
5802 to deliver the message flags to the application. Added also
5803 the `flags' arguments to the silc_client_send_channel_message
5804 and silc_client_send_private_message functions. Affected file
5807 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5809 * Redefined the Private Message Payload to support private message
5810 keys and to support the new private message flags. Updated
5811 the protocol specs. Flags makes it possible to have for example
5812 CTCP style messages.
5814 * Added new type SilcPrivateMessagePayload and defined an API
5815 for it in the lib/silcclient/silcprivate.[ch].
5817 * Tested private message private keys successfully. Tested the
5818 private message key set, unset and list commands with the new
5821 * Redefined the Channel Message Payload to include the channel
5822 message flags (equal with private message flags) to support
5823 for example CTCP style messages.
5825 * Defined some of the message (for channel and private message)
5826 flags. Updated the protocol specs and added the flags to the
5827 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5829 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5831 * Added SilcKeyAgreementStatus type to the key agreement routines
5832 to indicate the current status and error if one occured.
5833 The status types are defined in the lib/silcclient/silcapi.h.
5835 * Added new local command KEY that is used to set and unset private
5836 keys for channels, set and unset private keys for private messages
5837 with remote clients and to send key agreement requests and
5838 negotiate the key agreement protocol with remote client. The
5839 key agreement is supported only to negotiate private message keys,
5840 it currently cannot be used to negotiate private keys for channels,
5841 as it is not convenient for that purpose.
5843 * Fixed a minor pending callback setting bug in the function
5844 silc_client_get_client_by_id_resolve, now the function works.
5845 Affected file lib/silcclient/idlist.c.
5847 * Added function silc_net_get_local_port to get local bound
5848 port by socket. Added to lib/silcutil/silcnet.[ch].
5850 * Added `sockets' and `sockets_count' fields to the SilcClient
5851 object. They hold the sockets of the listenning sockets in
5852 the client. Listenning sockets may be for example the key
5853 agreement server. Affected file lib/silcclient/client.[ch].
5854 Added functions the silc_client_add_socket and the
5855 silc_client_del_socket. They are exported to the application
5858 * Added ~./silc/clientkeys to support other client's public keys.
5860 * Renamed verify_server_key client operation to verify_public_key
5861 and added one argument to indicate the type of the connection
5862 (server, client etc.).
5864 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5866 * Added silc_server_connection_auth_request to handle the
5867 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5868 silcd/packet_receive.[ch].
5870 * Added silc_server_send_connection_auth_request into the
5871 silcd/packet_send.c to send the connection auth request packet.
5873 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5876 * Fixed the public key authentication in responder side in the
5877 server. The `auth_data' pointer includes the SilcPublicKey
5878 not the path to the public key. Affected file silcd/protocol.c.
5880 * Implemented the public key authentication in the initiator side
5881 in the server. Affected file silcd/protocol.c.
5883 * Removed the [RedirectClient] config section from the server
5884 configuration. Is not needed and I don't want to implement it.
5886 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5888 * Cleaned up the CMODE command in the server. It now works
5889 correctly and supports all the modes defined in the protocol.
5890 Affected file is silcd/command.c.
5892 * Added `hmac_name' field to the SilcChannelEntry in the server
5893 to hold the default HMAC of the channel. It can be set when
5894 creating the channel (with JOIN command). Affected files
5897 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5898 type to indicate the change of the current cipher and hmac
5899 on the channel. Client can safely ignore the <cipher> argument
5900 (if it chooses to do so) since the CHANNEL_KEY packet will
5901 force the channel key change anyway. The <hmac> argument is
5902 important since the client is responsible of setting the new
5903 HMAC and the hmac key into use.
5905 * Fixed the CMODE command in the client library as well.
5907 * Tested CMODE command in router environment successfully.
5909 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5911 * Show the version of the remote client (or server) when connecting
5912 to the server. It is logged to the log file. Affected file
5913 is silcd/protocol.c.
5915 * Fixed the KILLED notify handling in the client library. The
5916 client must be removed from all channels when receiving the
5919 Also, do not remove the client entry when giving the KILL
5920 command but when the KILLED notify is received.
5922 * Removed silc_idlist_find_client_by_nickname from the server.
5923 Not needed anymore. Affected files silcd/idlist.[ch].
5925 * Implemented the CHANNEL_CHANGE notify type handling to the
5926 server. Affected file silcd/server.c.
5930 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5932 * Added silc_server_send_notify_invite to send the INVITE
5933 notify between routers.
5935 * Implemented the INVITE command correctly to the server.
5937 * Implemented the INVITE notify type handling in the server.
5939 * Implemented the INVITE command to the client library and on the
5942 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5944 * Added function silc_server_get_client_resolve to find the
5945 client entry by ID from all ID lists and then resolve it
5946 (using WHOIS) if it cannot be found. Affected file is
5949 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5951 * Implemented the BAN command to the client library.
5953 * The JOIN command in the server now checks the invite list
5956 * Changed the silc_command_reply_payload_encode_va and the
5957 silc_command_payload_encode_va to support that if argument is
5958 NULL it ignores and checks the next argument. Affected file
5959 lib/silccore/silccommand.c.
5961 * Added silc_server_send_notify_ban to send the BAN notify
5962 type between routers.
5964 * Chaned the silc_notify_payload_encode to support that if
5965 argument is NULL it ignores and checks the next argument.
5966 Affected file lib/silccore/silcnotify.c.
5968 * Tested ban lists in router environment successfully.
5970 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5972 * Implemented BAN command to the server, in silcd/command.[ch].
5974 * Removed the BAN and INVITE_LIST modes from the CMODE command
5977 * Added function silc_string_match to regex match two strings.
5978 Affected files lib/silcutil/silcutil.[ch].
5980 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5982 * Redefined parts of the SilcChannelEntry in the server to support
5983 the new ban and invite lists.
5985 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5987 * Redefined the INVITE command. The same command can be used to
5988 invite individuals to the channel but also to manage the invite
5989 list of the channel (to add to and remove from the invite list).
5990 Updated the protocol specs.
5992 * Added new command SILC_COMMAND_BAN that can be used to manage
5993 the ban list of the channel. Updated the protocol specs.
5995 * Removed the channel modes: the SILC_CMODE_BAN and the
5996 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5997 in the CMODE command. The equivalent features are now available
5998 using INVITE and BAN commands. Updated the protocol specs.
6000 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
6001 in the network about change in the current ban list. The notify
6002 type is not used by the client.
6004 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
6005 support the invite lists.
6007 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6009 * Added new function silc_string_regexify that converts string
6010 including wildcard characters into regex string that can
6011 be used by the GNU regex library. Added into the file
6012 lib/silcutil/silcutil.[ch].
6014 Added silc_string_regex_combine to combine to regex strings
6015 into one so that they can be used as one regex string by
6016 the GNU regex library. Added into the file
6017 lib/silcutil/silcutil.[ch].
6019 Added silc_string_regex_match to match two strings. It returns
6020 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
6022 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6024 * Imported GNU regex to the soruce tree into lib/contrib.
6025 Fixed some compiler warning from the regex.c.
6027 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6029 * Fixed MOTD command in the server to work in router environment.
6031 * Fixed the MOTD command in the client library to support
6032 the server argument in the command.
6034 * Added `nickname_len' argument to the silc_idlist_add_client
6035 in the server, as the `nickname' argument may be binary data
6038 * Added silc_idlist_get_channels to return all channels from
6041 * Implemented LIST command to the server. Affected file is
6044 * Implemented the LIST command to the client library and on the
6047 * Added [<user count>] argument to the LIST command reply.
6048 With private channels the user count is not shown.
6050 * Updated TODO and README.
6052 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6054 * The client entry's data.registered must be TRUE even with
6055 global client entry on global client list. The data.registered
6056 is used to check whether the client is anymore in the network,
6057 for example with WHOWAS command so it must be valid.
6059 * Fixed the WHOWAS command in the server. It now actually works
6060 in router environment. Added function into silcd/command_reply.c
6061 silc_server_command_reply_whowas_save.
6063 * Added silc_idlist_purge function to the silcd/idlist.c
6064 to periodically purge the ID Cache.
6066 * Fixed INFO command in the server. It works now in router
6067 environment. Added <server name> argument to the INFO command
6068 reply. Updated the protocol specs.
6070 * Fixed minor bug in silc_idcache_purge to not purge if the
6071 expire value is zero.
6073 * Fixed various bugs in WHOIS and IDENTIFY command handling as
6074 they were buggy because of the WHOWAS information.
6076 * Fixed local command MSG to handle the async resolving of
6077 the remote client properly. It used to fail the first MSG.
6078 Affected file silc/local_command.c.
6080 * Added `data_len' field to SilcIDCache context.
6082 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6084 * Update TODO. Todo in commands in the server.
6086 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6088 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
6089 used by routers as broadcast packet to inform other routers
6090 about the changed user mode.
6092 Implemented the notify handling in the server. Affected file is
6093 silcd/packet_receive.c. Added the function
6094 silc_server_send_notify_umode to the silcd/packet_send.[ch].
6096 * Added new generic Channel Payload and deprecated the New Channel
6097 Payload. The New Channel Payload is now the generic Channel
6100 * Added new argument `mode' to the silc_server_send_new_channel
6101 as it is required in the Channel Payload now.
6103 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
6104 and created a new and real SilChannelPayload to represent the
6105 new generic Channel Payload. Implemented the encode/decode
6106 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
6108 * Added silc_server_get_client_channel_list to return the list
6109 of channels the client has joined for WHOIS command reply.
6110 Affected file silcd/server.[ch].
6112 * Implemented the channel list sending in the WHOIS command reply
6113 in server and in the client.
6115 Implemented the channel list displaying on the user interface
6116 as well. Affected file silc/client_ops.c.
6118 * Added silc_channel_payload_parse_list to parse list of Channel
6119 Payloads. It returns SilcDList list of SilcChannelPayloads.
6120 Client for example can use this function to parse the list of
6121 channels it receives in the WHOIS command reply. The caller
6122 must free the list by calling silc_channel_payload_list_free.
6123 Affected files lib/silccore/silcchannel.[ch].
6125 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6127 * Added one new argument <user mode> to the WHOIS command reply
6128 to return the mode of the user in SILC. Updated the protocol
6131 Implemented it to the server and client.
6133 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6135 * Fixed the mode printing on the user interface on joining.
6136 Affected file silc/client_ops.c.
6138 * Implemented the UMODE command and user modes in general to the
6139 client library and to the user interface.
6141 * Implemented the UMODE command to the server.
6143 * The server now sends UNKNOWN_COMMAND error status if client sends
6144 unknown command. Affected file silcd/command.c.
6146 * All server commands now handle the command identifier the right
6147 way when sending the command reply to the client. The client can
6148 use to identify the command replies with the identifier.
6150 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6152 * Added silc_server_get_client_route to resolve the route to
6153 the client indicated by the client ID. Affected file is
6156 * Added silc_server_relay_packet as general function to relay
6157 packet to arbitrary destination. This deprecates functions
6158 like _send_private_message_key, _relay_notify etc. Affected
6159 file is silcd/packet_send.[ch].
6161 Removed silc_server_send_key_agreement,
6162 silc_server_send_private_message_key and
6163 silc_server_packet_relay_notify functions from the file
6164 silcd/packet_send.[ch].
6168 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
6169 server. Affected file silcd/packet_receive.[ch].
6171 * Implemented the KILL command to the client. Implemented the
6172 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
6173 Affected files lib/silcclient/command[_reply].c and
6174 lib/silcclient/client_notify.c. Implemented the KILL notify
6175 printing in the user inteface.
6177 * Fixed a lot silc_parse_nick memory leaks from the client
6178 library in the file lib/silcclient/command.c.
6180 * Changed the silc_server_send_notify_on_channels's `sender'
6181 argument from SilcSocketConnection to SilcClientEntry to
6182 check the sender as entry and not as connection object and not
6183 to send to the client provided as argument. The affected file
6184 is silcd/packet_send.[ch].
6186 * The notify packets that are destined directly to the client used
6187 to not to be processed by the server. Now changed that and the
6188 server processes all notify packets. After relaying the packet
6189 to the client the notify packet is processed in the server.
6191 * The silc_server_free_client_data now checks whether there is
6192 pending outgoing traffic for the client and purges the data to
6193 the network before removing the client entry.
6195 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6197 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
6198 an client is killed from the SILC Network. Updated the protocol
6201 Added new function silc_server_send_notify_killed to the
6202 silcd/packet_send.[ch].
6204 * Added function silc_server_packet_relay_notify to relay notify
6205 packets that are destined directly to a client. In this case
6206 the server does not process the notify packets but merely relays
6207 it to the client. Affected file silcd/packet_send.[ch].
6209 Added also silc_server_packet_process_relay_notify to check
6210 whereto relay the notify. Affected file is
6211 silcd/packet_receive.[ch].
6213 * Implemented the KILL command to the server.
6217 * Added the backup schema desgined last fall to the protocol
6218 specs for everyone to see. The specification is in the
6219 *-spec-xx.txt draft and the packet type definitions for the
6220 backup routers is in *-pp-xx.txt draft. Thusly, added also
6221 new packet type SILC_PACKET_CELL_ROUTERS.
6223 * A big security problem in the implementation discovered. The
6224 signoff of an client did not cause new channel key generation
6225 which it of course should've done. The channel keys must be
6226 always re-generated when client leaves (or signoffs) the channel.
6227 The silc_server_remove_from_channels funtion now handles
6228 the channel key re-generation.
6230 * Added `sender' argument to the silc_server_send_notify_on_channels
6231 to not to send the client provided as argument. Affected file
6232 silcd/packet_send.[ch].
6234 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6236 * Implemented OPER and SILCOPER commands into the server and
6239 * Added silc_auth_verify and silc_auth_verify_data to verify
6240 the authentication directly from the authentication payload.
6241 It supports verifying both passphrase and public key based
6242 authentication. Affected file lib/silccore/silcauth.[ch].
6244 * Added `hash' field to the SilcIDListData structure. It is the
6245 hash negotiated in the SKE protocol. Affected file is
6248 * Slight redesigning of the SilcAuthPayload handling routines.
6249 Do not send SilcPKCS but SilcPublicKey as argument.
6251 * Implemented the public key authentication support to the
6252 serverconfig. The public key is loaded from the provided path
6253 and saved as authentication data to void * pointer. Thus,
6254 changed the unsigned char *auth_data to void *auth_data;
6256 * Fixed SHUTDOWN command to send the reply before the server
6257 is shutdown. :) Affected file silcd/command.c.
6259 * Fixed fatal bug in CONNECT command. The hostname was invalid
6260 memory and server crashed. Affected file silcd/command.c.
6262 * Fixed fatal bug in CLOSE command. The server_entry became
6263 invalid but was referenced later in the command. Affected file
6266 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6268 * Fixed fatal bug in failure packet handling. Server ignored
6269 the failure and thus crashed when it came.
6273 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6275 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
6276 that the command may be executed only once in (about) 2 seconds.
6277 The old SILC_CF_LAG flag is same but allows command bursts up
6278 to five before limiting.
6280 Added the support for CF_LAG and CF_LAG_STRICT flags to the
6281 server code. Various commands now includes the CF_LAG_STRICT
6282 flag to disallow any kind of miss-use of the command.
6284 * Fixed the silc_buffer_unformat to not to allocate any data
6285 if the length of the data is zero. It used to allocate the
6286 length + 1. Affected file lib/silcutil/silcbuffmt.c.
6288 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6290 * Changed the format of AdminConnection configuration section
6291 in the server. Added username of the admin to the format.
6292 Affected files silcd/serverconfig.[ch].
6294 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
6295 to return admin configuration data by host, username and/or
6298 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6300 * Implemented WHOWAS command to the server. Added the functions:
6302 silc_server_command_whowas_parse,
6303 silc_server_command_whowas_send_reply,
6304 silc_server_command_whowas_from_client and
6305 silc_server_command_whowas_from_server
6307 * Added <Client ID> argument to the WHOWAS command reply. Updated
6308 the protocol specs accordingly.
6310 * Implemented WHOWAS command and command_reply to the client
6313 Implemented the WHOWAS printing on the user interface.
6315 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6317 * Added new argument to the WHOWAS command reply, the real name.
6318 It is an optional argument. Updated the protocol specs.
6320 * Added SilcIDCacheDestructor callback that is registered when
6321 the SilcIDCache is allocated. The callback is called when
6322 an cache entry in the ID Cache expires, or is purged from the
6323 cache. Added into lib/silccore/idcache.[ch].
6325 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
6326 to destruct the client entries when the cache entry expires.
6327 Other ID Cache's in server and in the client library ignores
6330 * If the ID Cache entry's `expire' field is zero then the entry
6331 never expires. Added boolean `expire' argument to the
6332 silc_idcache_add function in the lib/silccore/idcache.[ch].
6333 If it is TRUE the default expiry value is used.
6335 * Added silc_server_free_client_data_timeout that is registered
6336 when client disconnects. By default for 5 minutes we preserve
6337 the client entry for history - for WHOWAS command.
6339 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6341 * Added support to the server to enforce that commands are not
6342 executed more than once in 2 seconds. If server receives
6343 commands from client more frequently, timeout is registered
6344 to process the commands. Affected file silcd/command.c.
6345 Added new function silc_server_command_process_timeout.
6347 * Changed NICK_NOTIFY handling in client library to check that
6348 if the client's nickname was changed, so there is no need to
6349 resolve anything from the server.
6351 * Removed error printing from the WHOIS and IDENTIFY commands.
6352 If error occurs then it is ignored silently in the client library.
6353 The application, however, may map the received error to
6354 human readable error string. The application currently maps
6355 the NO_SUCH_NICKNAME error to string.
6357 * Made the command status message public to the application. Moved
6358 them from lib/silcclient/command_reply.c to
6359 lib/silcclient/command_reply.h. The application can map the
6360 received command status to the string with the
6361 silc_client_command_status_message function.
6363 * Added check to the server to check that client's ID is same
6364 as the Source ID in the packet the client sent. They must
6367 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6369 * Added dist-bzip hook to the Makefile.am to make bzip2
6370 compressed distributions.
6372 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6374 * Server now enforces the maximum length for the nickname and
6375 the channel as protocol specification dictates. 128 bytes for
6376 nickname and 256 bytes for channel name.
6378 * Moved the WHOIS printing to the application. The client libary
6379 does not print out the WHOIS information anymore, the application
6380 must do it. Renamed silc_client_command_reply_whois_print to
6381 the silc_client_command_reply_whois_save.
6383 The client's idle time is also sent to the application now, and
6384 the idle is shown on screen.
6386 * Added silc_client_command_reply_identify_save to save the
6387 received IDENTIFY entries.
6389 * Do not check for channel private keys in message sending and
6390 reception if the channel does not have the PRIVKEY mode set.
6391 Affected file lib/silclient/client_channel.c.
6393 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6395 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
6396 just surfaced after chaning the JOIN procedure.
6398 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6400 * Added silc_client_get_clients_by_list to get client entries
6401 from Client ID list, that is returned for example by JOIN
6402 and USERS command replies. The application should use this
6403 function for example when JOIN command reply is received to
6404 resolve the clients already on the channel (library does not
6405 do that anymore as USERS command reply is not used in the JOIN
6406 procedure anymore). Affected files lib/silcclient/silcapi.h and
6407 lib/silcclient/idlist.c.
6409 * JOIN command reply and USERS command reply returns now SilcBuffer
6410 pointers instead of unsigned char pointers when returning
6411 the client list and mode list.
6413 * Added <Client ID> argument to the JOIN command reply, mainly
6414 for the server to identify for which client the command was
6415 originally sent. Updated protocol specs accordingly.
6417 * Added SilcDlist private_key pointer to the SilcChannelEntry
6418 in the client to support the channel private keys. Affected
6419 file is lib/silcclient/idlist.h.
6421 * Added SilcChannelPrivateKey argument to the function
6422 silc_client_send_channel_message so that application can choose
6423 to use specific private ke if it wants to. If it is not provided,
6424 the normal channel key is used, unless private keys are set.
6425 In this case the first (key that was added first) is used
6426 as the encryption key.
6428 * Implemented the support for channel private key handling.
6429 Implemented the following functions:
6431 silc_client_add_channel_private_key,
6432 silc_client_del_channel_private_keys,
6433 silc_client_del_channel_private_key,
6434 silc_client_list_channel_private_keys and
6435 silc_client_free_channel_private_keys
6437 Affected file lib/silcclient/client_channel.c.
6439 * Added the support for the private keys in the channel message
6440 sending and encryption and in the message reception and
6441 decryption. Affected funtions are
6442 silc_client_send_channel_message and silc_client_channel_message.
6444 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6446 * Added SKE's key verify callback to the client library's
6447 KE protocol context. Affected files lib/silcclient/protocol.[ch].
6449 * Removed the statement that server (or router) must send USERS
6450 command reply when joining to the channel so that the client
6451 knows who are on the channel. Instead, the client list and
6452 client's mode list is now sent in the JOIN command reply to the
6453 client who joined channel. This is better solution.
6455 * Added function silc_server_get_users_on_channel and function
6456 silc_server_save_users_on_channel to the silcd/server.[ch].
6458 * Removed function silc_server_command_send_users from the
6461 * Do not show topic on the client library anymore. The topic is
6462 sent in the command reply notify to the application and the
6463 application must show the topic now.
6465 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6467 * Added client searching by nickname hash into the IDENTIFY and
6468 WHOIS commands in the server as they were clearly missing from
6469 them. Affected file is silcd/command.c.
6471 * Fixed a bug in private message receiving in the client library.
6472 The remote ID was freed and it wasn't supposed, now it is
6475 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6477 * Minor fix to the channel payload; allocate the data area, as it
6478 needs to be of specific length.
6480 * If the key agreement port is zero then the operating
6481 system will define the bound port. Affected files are
6482 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
6484 * Added new function silc_channel_payload_decrypt into the file
6485 lib/silccore/silcchannel.[ch].
6487 * Moved the channel message etc, check from silc_packet_decrypt
6488 to applications. The library calls now a generic
6489 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
6490 when the packet is either normal or special. This was done to
6491 allow more wide range of checking that was not allowed when
6492 the code was in library. Now applications can do virtually any
6493 checks to the packet and return to the library the decision how
6494 the packet should be processed. Affected files are
6495 lib/silccore/silcpacket.[ch].
6497 Added silc_server_packet_decrypt_check to the server and
6498 silc_client_packet_decrypt_check to the client library.
6500 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
6501 to send with specified source and destination information.
6503 * Channel message delivery between routers was broken after the
6504 channel key distribution was fixed earlier. The channel key
6505 was used be to distributed to other routers as well which is not
6506 allowed by the protocol. Now this is fixed and channel keys
6507 really are cell specific and the channel message delivery between
6508 routers comply with the protocol specification.
6510 * Fixed various commands in server to check also the global list
6511 for the channel entry and not just the local list. The affected
6512 file silcd/command.c.
6514 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6516 * Added assert()s to buffer formatting and unformatting routines
6517 to assert (if --enable-debug) when error occurs. Affected
6518 file: lib/silcutil/silcbuffmt.c.
6520 * Changed to auto-reconnect to check whether the remote host is
6521 router and register the re-connect timeout if it is. It used
6522 to check that whether we are normal server, but router must do
6523 auto-reconnect with another router as well. Affected file
6526 * Removed the [<key len>] option from CMODE command as the cipher
6527 name decides the key length, nowadays. See the defined ciphers
6528 from the protocol specification.
6530 * Added [<hmac>] option to the CMODE command to define the HMAC
6531 for the channel. Added SILC_CMODE_HMAC channel mode.
6533 * Added [<hmac>] option for the JOIN command so that user can
6534 select which HMAC is used to compute the MACs of the channel
6537 * Added Hmac field to the Channel Message Payload. The integrity
6538 of plaintext channel messages are now protected by computing
6539 MAC of the message and attaching the MAC to the payload. The
6540 MAC is encrypted. Now, it is clear that this causes some
6541 overhead to the size of the packet but rationale for this is that
6542 now the receiver can verify whether the channel message decrypted
6543 correctly and also when private keys are set for the channel the
6544 receiver can decrypt the packet with several keys and check from
6545 the MAC which key decrypted the message correctly.
6547 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
6548 lib/silccrypt/silccipher.[ch].
6550 * Added silc_hash_len to return the digest length into the
6551 lib/silcrypt/silchash.[ch].
6553 * Rewrote parts of Silc Channel Payload interface in the
6554 lib/silccore/silcchannel.[ch]. The encode function now also
6555 encrypts the packet and parse function decrypts it.
6557 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6559 * Fixed a minor formatting bug in the SKE's key material processing.
6560 It actually might have processed the keys wrong way resulting
6563 * Redefined the mandatory HMAC algorithms and added new algorithms.
6564 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
6565 and hmac-md5 truncated to 96 bits. The mandatory is now
6566 hmac-sha1-96. Rest are optional (including the one that used
6567 to be mandatory). Rationale for this is that the truncated HMAC
6568 length is sufficient from security point of view and can actually
6569 make the attack against the HMAC harder. Also, the truncated
6570 HMAC causes less overhead to the packets. See the RFC2104 for
6573 * Added new [hmac] configuration section. The SKE used to use
6574 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
6575 is of course wrong. The official names that must be proposed in
6576 the SKE are the ones defined in the protocol specification
6577 (hmac-sha1-96 for example). The user can configure any hmac
6578 using any hash function configured in the [hash] section. At
6579 least, the mandatory must be configured.
6581 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
6583 * Added HMAC list to the SKE proposal list. It has now both
6584 hash algorithm list and HMAC list. This makes the protocol
6585 incompatible with previous versions. The SKE now seems to work
6586 the way it is supposed to work, for the first time actually.
6588 * Defined plain Hash algorithms to the protocol specification.
6591 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6593 * Implemented support for key agreement packets into the server.
6594 Added functions silc_server_key_agreement and
6595 silc_server_send_key_agreement. Other than these functions,
6596 server has nothing to do with this packet.
6598 * Added support for private message key packets into the server.
6599 Added functions silc_server_private_message_key and
6600 silc_server_send_private_message_key.
6604 * Changed the silc_[client|server]_protocol_ke_set_keys to be
6605 called in the protocol's final callback instead in the END
6606 protocol state. This makes a little more sense and in the same
6607 time in client we can use the same protocol routines for normal
6608 key exchange and to key agreement packet handling as well.
6610 * Added to both client's and server's KE protocol context the
6611 SilcSKEKeyMaterial pointer to save the key material. We will
6612 bring the key material to the protocol's final callback by doing
6613 this. The final callback must free the key material.
6615 * Added SKE's packet_send callback into client's KE protocol
6616 context so that the caller can choose what packet sending function
6617 is used. This way we can use different packet sending when
6618 doing normal SKE when doing key agreement packet handling (in
6619 the key agreement packet handling we do not want to encrypt
6622 * Implemented the responder side of the key agreement routines
6623 in the client. The client can now bind to specified port and
6624 accept incoming key negotiation. The key material is passed
6625 to the application after the protocol is over.
6627 * Implemented the processing of incoming Key Agreement packet
6628 in the client. Added function silc_client_key_agreement to
6631 * Implemented the intiator side of the key agreement routines
6632 in the client. The client can now initiate key agreement with
6633 another remote client. The key material is passed to the
6634 application after the protocol is over.
6636 * Created client_keyagr.c to include all the key agreement
6639 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
6640 SILC_TASK_CALLBACK except that it is not static.
6642 * Created client_notify.c and moved the Notify packet handling
6643 from the client.[ch] into that file.
6645 * Created client_prvmsg.c and moved all private message and
6646 private message key routines from the client.[ch] into that file.
6648 * Create client_channel.c and moved all channel message and
6649 channel private key routines from the client.[ch] into that file.
6651 * Changed silc_client_get_client_by_id_resolve to resolve with
6652 WHOIS command instead of IDENTIFY command, in the file
6653 lib/silclient/idlist.c.
6655 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6657 * Implemented the SKE's responder side to the Client library.
6659 * When FAILURE is received to the protocol do not trust it
6660 blindly. Register a timeout to wait whether the remote closes
6661 the connection as it should do it, only after that process the
6662 actual failure. This was changed to both client and server.
6664 * Added client_internal.h to include some of the structures
6665 there instead of client.h in lib/silcclient/.
6667 * Added function silc_task_unregister_by_callback to unregister
6668 timeouts by the callback function.
6670 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6672 * Some "Incomplete WHOIS info" errors has been appearing on the
6673 log files. Took away the entry->userinfo check from WHOIS
6674 reply sending. The entry->userinfo is now " " if client did not
6675 provide one. I thought this was fixed earlier but something
6676 is wrong still. Let's see if the error still appears.
6678 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6680 * Fixed a minor bug in the login when the channel key is
6681 re-generated in the server. It used to generate the key in
6682 wrong order and thus caused problems in the channel traffic.
6684 * Fixed a minor bug in channel key distsribution after
6685 KICK command. The key was not sent to the router even though
6688 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6690 * Added silc_ske_process_key_material_data as generic routine
6691 to process any key material as the SILC protocol dictates. The
6692 function is used by the actual SKE library but can be used by
6693 applications as well. This relates to the private message keys
6694 and the channel private keys since they must be processed the
6695 same way the normal SILC session keys. The protocol dictates
6696 this. Affected files: lib/silcske/silcske.[ch].
6698 Added also silc_ske_free_key_material to free the
6699 SilcSKEKeyMaterial structure.
6701 * Defined silc_cipher_set_key function to set the key for
6702 cipher without using the object's method function. The affected
6703 files: lib/silccrypt/silccipher.[ch].
6705 * Implemented silc silc_client_add_private_message_key,
6706 silc_client_add_private_message_key_ske,
6707 silc_client_del_private_message_key,
6708 silc_client_list_private_message_keys and
6709 silc_client_free_private_message_keys functions in the
6712 Added functions silc_client_send_private_message_key to send
6713 the Private Message Key payload and silc_client_private_message_key
6714 to handle incoming Private Message Key payload.
6716 * Added Cipher field to the Private Message Key payload to set
6717 the cipher to be used. If ignored, the default cipher defined
6718 in the SILC protocol (aes-256-cbc) is used.
6720 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6722 * Removed lib/silcclient/ops.h file.
6724 Redefined parts of the SILC Client Library API. Created new
6725 file silcapi.h that deprecates the ops.h file and defines the
6726 published Client Library API. Defined also private message key
6727 API and channel private key API into the file.
6729 This is the file that the application must include from the
6730 SILC Client Library. Other files need not be included by
6731 the application anymore.
6733 * Added new key_agreement client operation callback and also
6734 defined the Key Agreement library API for the application.
6736 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6738 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
6739 is used by clients to request key negotiation between another
6740 client in the SILC network. If the negotiation is started it
6741 is performed using the SKE protocol. The result of the
6742 negotiation, the secret key material, can be used for example
6743 as private message key.
6745 Implemented the Key Agreement payload into the files
6746 lib/silccore/silauth.[ch].
6748 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6750 * Redefined ciphers for the SILC protocol. Added some new ciphers
6751 and defined the key lengths for the algorithms. Changed the
6752 code accordingly. The default key length is now 256 bits.
6754 * Fixed SKE key distribution function silc_ske_process_key_material
6755 when the key length is more than 128 bits. The default key
6756 length in SILC is now 256 bits.
6758 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
6759 to indicate unsupported algorithm.
6761 * Renamed rijndael.c to aes.c and all functions as well.
6763 * Fixed a long standing channel key setting bug in client library.
6764 Weird that it has never surfaced before.
6766 * Fixed bug in channel deletion. If the entire channel is removed
6767 then it must also delete the references of the channel entry
6768 from the client's channel list as the client's channel entry and
6769 the channel's client entry share same memory.
6771 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6773 * Implemented CONNECT and SHUTDOWN commands in the client.
6775 * Implemented CLOSE command to the client.
6777 * Added the function silc_idlist_find_server_by_name into the
6778 files silcd/idlist.[ch].
6780 Added the function silc_idlist_find_server_by_conn into the
6781 files silcd/idlist.[ch].
6783 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6785 * DIE command was renamed to SHUTDOWN. Updated the both code
6788 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
6789 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
6791 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
6794 * Added function silc_server_create_connection function to create
6795 connection to remote router. My server implementation actually
6796 does not allow router to connect to normal server (it expects
6797 that normal server always initiates the connection to the router)
6798 so the CONNECT command is only good for connecting to another
6801 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6803 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
6804 or some other client was kicked from the channel.
6806 Implemented the handling of the notify type to both client
6809 Implemented silc_server_send_notify_kicked to send the KICKED
6810 notify. It is used to send it to the server's primary router.
6812 * Implemented the KICK command into server and client.
6814 * Added `query' argument to the silc_idlist_get_client function
6815 to indicate whether to query the client from server or not if
6818 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
6819 to indicate that the client is not channel founder.
6823 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6825 * Removed the rng context from SilcPacketContext structure and
6826 changed that the packet routine uses the Global RNG API.
6828 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6830 * Added support for quit message that client can "leave" on the
6831 channel when it quits the SILC. It is ditributed inside the
6832 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6834 Added silc_server_free_client_data that will take the
6835 signoff message as argument.
6837 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6839 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6841 * Updated parts of the protocol specification to keep it up
6844 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6846 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6847 payloads in one packet.
6849 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6850 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6851 use now the new List flag.
6853 * Also deprecated the following packet types: REPLACE_ID,
6854 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6856 * Added list support for Notify packet in server.
6858 * Added silc_server_send_notify_channel_change to send the
6859 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6860 the silc_server_send_replace_id.
6862 * Added silc_server_send_notify_nick_change to send the
6863 NICK_CHANGE notify type. Deprecates the function
6864 silc_server_send_replace_id.
6866 * Added silc_server_send_notify_join to send the JOIN notify type.
6867 Deprecates the function silc_server_send_new_channel_user.
6869 * Added silc_server_send_notify_leave to send LEAVE notify type.
6870 Deprecates the function silc_server_send_remove_channel_user.
6872 * Added silc_server_send_notify_cmode and
6873 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6874 types. Deprecates the silc_server_send_set_mode function.
6876 * Added SERVER_SIGNOFF notify type to indicate that server has
6877 quit. This means that all clients on the channel from that
6878 server will drop. This can be also used when netsplit happens.
6880 Deprecated REMOVE_ID packet type since it is not needed anymore
6883 Added silc_server_send_notify_server_signoff to send the
6884 SERVER_SIGNOFF notify type. Deprecates the function
6885 silc_server_send_remove_id.
6887 Added also silc_server_send_notify_signoff to send the
6888 SIGNOFF notify type.
6890 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6891 SILC protocol from this day on. Changed the protocol
6892 specification as well.
6894 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6895 notify type. It is used between routers to notify about
6896 topic changes on a channel.
6898 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6901 * Partly updated the protocol specification to comply with the
6902 changes now made. It is still though a bit outdated.
6904 * The JOIN notify type now takes one extra argument <Channel ID>.
6905 The packet used to be destined to the channel but now the
6906 JOIN type may be sent as list thus it is impossible to
6907 destine it to any specific channel. By adding this argument
6908 it is again possible.
6910 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6912 * Added CREDITS file. The CHANGES and CREDITS file will appear
6913 in the distribution as well.
6915 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6917 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6918 types in the server's silcd/packet_receive.c.
6920 * Implemented CMODE and CUMODE to work in router environment.
6922 * Fixed minor encoding and decoding buglet from the
6923 lib/silccore/silcmode.c.
6925 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6928 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6930 * Changed all SilcConfigServer* and silc_config_server* to
6931 SilcServerConfig* and silc_server_config*, respectively.
6934 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6936 * Associated the ID (client or server ID) to the Authentication
6937 Payload to avoid any possibility of forging. Updated the
6938 protocol specification and the code accordingly.
6940 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6942 * The RSA key length is now save to the RsaKey context in the
6943 key generation process in lib/silccrypt/rsa.c. The key length
6944 is now used to figure out the maximum size of the block allowed
6945 to be encrypted/signed.
6947 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6948 is equivalent to the silc_mp_mp2bin but does not allocate any
6951 * Changed silc_mp_mp2bin API to take length argument. If it is
6952 non-zero then the buffer is allocated that large. If zero, then
6953 the size is approximated using silc_mp_sizeinbase, which however
6956 * Created Global RNG API which is global RNG that application can
6957 initialize. After initializing, any routine anywhere in the
6958 code (including library) can use RNG without allocating a new
6959 RNG object. This was done to allow this sort of use of the
6960 RNG in code that has no chance to allocate RNG object. All
6961 applications currently allocate this and many routines in the
6962 library use this. Affected file lib/silccrypt/silcrng.[ch].
6964 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6965 it to use the Global RNG API.
6967 * Defined Authentication Payload into protocol specification that
6968 is used during SILC session to authenticate entities. It is
6969 used for example by client to authenticate itself to the server
6970 to obtain server operator privileges.
6972 Implemented this payload into the lib/silccore/silcauth.[ch].
6973 Implemented also routines for public key based authentication
6974 as the new protocol specification dictates.
6976 Moved definitions of different authentication methods from
6977 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6979 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6980 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6981 silc_pkcs_verify_with_hash functions into the file
6982 lib/silccrypt/silcpkcs.[ch].
6984 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6986 * The client entry's userinfo pointer must be always valid.
6987 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6988 will fail since it requires the userinfo. Now, the userinfo
6989 is allocated as "" if actual userinfo does not exist. Actually,
6990 it must exist and it is totally Ok to drop client connections
6991 that does not announce the userinfo. However, we will make
6992 this workaround for now.
6994 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6995 to return the remote port by socket.
6997 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6999 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
7000 SILC_SERVER_PENDING_EXEC and added an new macro
7001 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
7002 data or when error occurs while processing the pending command.
7004 Added new argument `destructor' into silc_server_command_pending
7005 and to the SilcServerCommandPending object. This destructor is
7006 now called after calling the pending callback or if error occurs
7007 immediately. If error occurs the actual pending callback won't
7008 be called at all - only the destructor. The destructor may be
7009 NULL if destructor is not needed.
7011 All this applies for client library code as well. Similar
7012 changes were made there as well for the pending commands.
7014 In the client, the application must now allocate the
7015 SilcClientCommandContext with the silc_client_command_alloc
7018 * Added reference counter to the SilcServerCommandContext. Added
7019 function silc_server_command_alloc and silc_server_command_dup
7022 Same type of functions added to the client library for the same
7025 * Removed the cmd_ident from IDListData away since it is now
7026 global for all connections. It is the command identifier used
7027 in command sending and with pending commands. The affected file
7030 * Added reference counter to the SilcSocketConnection objecet to
7031 indicate the usage count of the object. The object won't be
7032 freed untill the reference counter hits zero. Currently only
7033 server uses this, and client ignores it. The client must be
7034 set to use this too later. The affected files are
7035 lib/silccore/silcsockconn.[ch]. Added also the function
7036 silc_socket_dup to increase the reference counter.
7038 This was mainly added because it is possible that the socket
7039 is removed underneath of pending command or other async
7040 operation. Now it won't be free'd and proper DISCONNECTING
7041 flags, etc. can be set to avoid sending data to connection that
7042 is not valid anymore.
7044 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
7045 the connection. After that it sets SILC_SET_DISCONNECTED.
7046 It is, however, possible that the socket data is not still freed.
7047 The silc_server_packet_process now checks that data is not
7048 read or written to connection that is DISCONNECTED. The socket
7049 get's freed when the reference counter hits zero.
7051 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7053 * Changed the client operation API: channel_message operation's
7054 `sender' is now the client entry of the sender, not the nickname
7055 and the `channel' is the channel entry, not the channel name.
7057 In the private_message operation the `sender' is now also the
7058 client entry of the sender not the nickname.
7060 Affected file is lib/silcclient/ops.h and all applications
7061 using the client operations.
7063 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7065 * Moved the calling of ops->connect() from connect_to_server_final
7066 into receive_new_id functin since that is the point when the
7067 client is actually allowed to send traffic to network. The
7068 affected file is lib/silcclient/client.c.
7070 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7072 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
7073 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
7074 (if needs broadcasting) instead of broadcasting the packets one
7075 by one which would make a burst in the network traffic.
7077 * Added `broadcast' argument to the functions in silcd/server.[ch]
7078 silc_server_create_new_channel[_with_id] to indicate whether
7079 to send New Channel packet to primary router.
7081 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7083 * Added new function into the silcd/server.[ch] files:
7084 silc_server_create_new_channel_with_id to create new channel with
7085 already existing Channel ID.
7087 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
7088 lib/silccore/silcpacket.h. This packet is used t send list of
7089 Set Mode payloads inside one packet. Server uses this to set
7090 the modes for the channels and clients on those channels, that it
7091 announced to the router when it connected to it. The protocol
7092 specification has been updated accordingly.
7094 * The silc_server_new_channel did not handle the packet coming
7095 from normal server as it normally does not send that. However,
7096 when it announces its channels it does send it. Implemented
7097 the support for that.
7099 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
7100 into the file lib/silccore/id.h.
7102 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7104 * Fixed memory leaks in the functions silc_idlist_del_client,
7105 silc_idlist_del_channel and silc_idlist_del_server in the file
7106 silcd/idlist.c. All of those leaked like a sieve.
7108 * Fixed some small memory leaks in the client's function
7109 silc_client_notify_by_server.
7111 * Added functions into silcd/server.c: silc_server_announce_clients,
7112 silc_server_announce_channels and silc_server_announce_server.
7113 These functions are used by normal and router server to announce
7114 to its primary router about clients, channels and servers (when
7115 router) that we own. This is done after we've connected to the
7118 These functions effectively implements the following packet types:
7119 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
7120 and SILC_PACKET_NEW_ID_LIST.
7122 * Added new functions into the silcd/packet_receive.[ch]:
7123 silc_server_new_id_list, silc_server_new_channel_list and
7124 silc_server_new_channel_user_list to handle the incoming
7125 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
7127 * Added support of changing Channel ID in the function
7128 silc_server_replace_id. If the server that announces a channel
7129 to the router already exists in the router (with same name but
7130 with different Channel ID), router is responsible to send
7131 Replace ID packet to the server and force the server to change
7132 the Channel ID to the one router has.
7134 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
7135 client that the Channel ID has been changed by the router. The
7136 normal server sends this to the client. Client must start using
7137 the new Channel ID as the channel's ID.
7139 Implemented handling of this new type into lib/silcclient/client.c
7140 into the function silc_client_notify_by_server.
7142 * Added new function silc_idlist_replace_channel_id into the files
7143 silcd/idlist.[ch] to replace the Channel ID.
7145 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7147 * Call silc_server_command_identify_check always when processing
7148 the IDENTIFY command in silcd/command.c
7150 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7152 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
7153 send keepalive packets. The packet can be sent by clients,
7154 servers and routers.
7156 Added function silc_socket_set_heartbeat into the file
7157 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
7158 If not set, the heartbeat is not performed. The actual
7159 heartbeat is implemented in the low level socket connection
7160 library. However, application is responsible of actually
7163 Added silc_server_send_heartbeat to send the actual heartbeat
7164 packet into silcd/packet_send.[ch]. Server now performs
7165 keepalive with all connections.
7167 * Added silc_task_get_first function into lib/silcutil/silctask.c
7168 to return the timeout task with shortest timeout. There was a bug
7169 in task unregistration that caused problems. TODO has been
7170 updated to include that task system must be rewritten.
7172 * The client library will now resolve the client information when
7173 receiving JOIN notify from server for client that we know but
7174 have incomplete information.
7176 * Rewrote parts of silc_server_remove_from_channels and
7177 silc_server_remove_from_one_channel as they did not remove the
7178 channel in some circumstances even though they should've.
7180 * Encryption problem encountered in server:
7182 The LEAVE command used to send the Channel Key packet to the
7183 router immediately after generating it. However, the code
7184 had earlier sent Remove Channel user packet but not immediately,
7185 ie. it was put to queue. The order of packets in the router
7186 was that Channel Key packet was first and Remove Channel User
7187 packet was second, even though they were encrypted in the
7188 reverse order. For this reason, MAC check failed. Now, this
7189 is fixed by not sending the Channel Key packet immediately but
7190 putting it to queue. However, this is more fundamental problem:
7191 packets that are in queue should actually not be encrypted
7192 because packets that are sent immediately gets encrypted
7193 actually with wrong IV (and thus MAC check fails). So, packets
7194 that are in queue should be encrypted when they are sent to
7195 the wire and not when they put to the queue.
7197 However, the problem is that the current system has not been
7198 designed to work that way. Instead, the packet is encrypted
7199 as soon as possible and left to the queue. The queue is then
7200 just purged into wire. There won't be any fixes for this
7201 any time soon. So, the current semantic for packet sending
7204 o If you send packet to remote host and do not force the send
7205 (the packet will be in queue) then all subsequent packets to the
7206 same remote host must also be put to the queue. Only after the
7207 queue has been purged is it safe again to force the packet
7210 o If you send all packets immediately then it safe to send
7211 any of subsequent packets through the queue, however, after
7212 the first packet is put to queue then any subsequent packets
7213 must also be put to the queue.
7215 Follow these rules and everything works fine.
7217 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7219 * Added new function silc_server_remove_clients_by_server to
7220 remove all client entries from ID list when the server connection
7221 is lost. In this case it is also important to invalidate all
7222 client entires as they hold the invalid server entry. This
7223 fixes fatal bug when server has lost connection and will reconnect
7226 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7228 * Made some sanity checks to silc_server_daemonise like to check
7229 whether the requested user and group actually exists.
7231 * Added sanity check to SKE's silc_ske_responder_finish to check
7232 that the public and private key actually is valid.
7234 * Invalidate the client's nickname when receiving Replace ID
7235 packet and the Client ID is being replaced. This means that the
7236 server will query the nickname if someone needs it (client)
7239 * Sort the ID Cache in client library when the ID Cache data
7240 has changed (needs sorting).
7242 * Do not allow for SILC client to create several connections to
7243 several servers. The client does not support windows right now
7244 and generating multiple connections causes weird behaviour.
7246 Irssi-silc client does support windows and can handle several
7247 connections without problems, see: www.irssi.org and SILC plugin.
7249 * Fixed some places where client was added to the IDList. The
7250 rule of thumb is following (in order to get everything right):
7251 If the client is directly connected local client then the
7252 `connection' argument must be set and `router' argument must be
7253 NULL to silc_idlist_add_client function. If the client is not
7254 directly connected client then the `router' argument must
7255 bet set and the `connection' argument must be NULL to the
7256 silc_idlist_add_client function.
7258 * The funtion silc_server_packet_send_local_channel actually did
7259 not check whether the client was locally connected or not. It
7260 does that now. Fixed a bug related to LEAVE command.
7262 * Fixed Remove Channel User payload parsing bug in server's
7263 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
7265 * The server's silc_server_save_channel_key now checks also the
7266 global ID list for the channel as it might not be in the local
7267 list. Fixed a bug related to LEAVE command.
7269 * Is this the end of the [<unknown>] buglet that has been lurking
7270 around for a long time? A little for loop fix in server's
7271 silc_server_command_whois_parse that is used by both IDENTIFY
7272 and WHOIS command. At least, this was a clear bug and a cause
7273 of one type of [<unknown>] buglet.
7275 * WHOIS and IDENTIFY commands call the function
7276 silc_server_command_[whois/identify]_check function even if
7277 we are not router server.
7279 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7281 * Added --with-gmp configuration option. If set the GMP
7282 is always compiled in the SILC source tree. If not set then
7283 it is checked whether the system has the GMP3 installed. If
7284 it has then the GMP won't be compiled (the system's headers
7285 and library is used), if it doesn't have it then the GMP is
7286 compiled in the SILC source tree.
7288 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7290 * Changed RSA private exponent generation to what PKCS #1
7291 suggests. We try to find the smallest possible d by doing
7292 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
7293 not security fix but optimization.
7295 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7297 * Added new config entry [Identity] to fork the server and run
7298 it as specific user and group. A patch from Bostik.
7300 * Imported Dotconf configuration library into lib/dotconf.
7301 This will be used to create the SILC configuration files later.
7302 It will appear in the distsribution after this commit.
7304 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7306 * A big code auditing weekend happening. Auditing code for
7307 obvious mistakes, bugs and errors. Also, removing any code
7310 Removed files for being obsolete:
7312 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
7313 inline in the file lib/silcutil/silcbuffer.h)
7315 o lib/silcutil/silcbufutil.c (the header has inline versions)
7317 Changed code to fix possible error conditions:
7319 o The buffer formatting routines now check that the destination
7320 buffer really has enough space to add the data. This applies for
7321 both buffer formatting and unformatting
7322 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
7323 unformatting was changed to accomodate following rules:
7324 XXX_*STRING_ALLOC will allocate space for the data into the pointer
7325 sent to the function while XXX_*STRING will not allocate or copy
7326 the data into the buffer. Instead it sets the pointer from the
7327 buffer into the pointer sent as argument (XXX_*STRING used to
7328 require that the pointer must be allocated already). This change
7329 makes this whole thing a bit more consistent and more optimized
7330 (note that the data returned in the unformatting with XXX_*STRING
7331 must not be freed now). The routines return now -1 on error.
7333 o Tried to find all code that use buffer_format and buffer_unformat
7334 and added return value checking to prevent formatting and
7335 especially unformatting errors and possible subsequent fatal
7338 o Changed ske->x and ske->KEY to mallocated pointers in
7339 lib/silcske/silcske.h. Fixed possible data and memory leak.
7341 o Added return value checking to all *_parse* functions. Fixed
7342 many memory leaks as well.
7344 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
7345 so that buffer overflows would not happen. All code now also
7346 checks the return value as it can fail.
7348 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7350 * Added reconnection support to server if the normal server looses
7351 its connection to the router (for example if router is rebooted).
7352 The server performs normal reconnection strategy implemented
7353 to the server. Affected file silcd/server.c.
7355 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7357 * Added new packet type SILC_PACKET_SET_MODE that is used to
7358 distribute the information about changed modes (for clients,
7359 channels and clients channel modes) to all routers in the
7360 network. Updated the protocol specification accordingly.
7362 Added functions into silcd/packet_send.c and
7363 silcd/packet_receive.c: silc_server_send_set_mode,
7364 silc_server_set_mode.
7366 Added new files silcmode.[ch] into lib/silccore that implements
7367 the encoding and decoding of Set Mode Payload. Added new type
7368 SilcSetModePayload. Moved the definitions of different modes
7369 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
7371 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7373 * Oops, a little mistake in server's connection authentication
7374 protocol. The protocol is not ended with FAILURE but with
7375 SUCCESS if the authentication is Ok. :) Affected file is
7378 * Implemented NICK_CHANGE notify handling in server in the file
7379 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
7380 the local clients on the channel. After the changing nickname
7381 in router environment snhould work and the [<unknown>] nickname
7382 should appear no more.
7384 The silc_server_replace_id function that receives the Replace ID
7385 payload now sends the NICK_CHANGE notify type also in the file
7386 silcd/packet_receive.c
7388 * Changed WHOIS and IDENTIFY command to support the maximum amount
7389 of arguments defined in protocol specs (3328 arguments). This
7390 fixed a bug that caused problems when there were more than three
7393 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7395 * Added extra parameter, command identifier, to the
7396 silc_client_send_command so that explicit command identifier
7399 Changed that ID list routines uses specific command identifier
7400 when sending WHOIS/IDENTIFY requests to the server so that they
7401 can be identified when the reply comes back.
7403 Affected files lib/silcclient/command.[ch],
7404 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
7406 * Added `sender' argument to silc_server_packet_send_to_channel
7407 to indicaet the sender who originally sent the packet to us
7408 that we are now re-sending. Ignored if NULL. Affected file
7409 silcd/packet_send.[ch].
7411 * Added some server statistics support in silcd/server_internal.h
7412 SilcServerStatistics structure and around the server code. Also
7413 send some nice statistics information when client is connecting
7416 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7418 * Fixed channel ID decoding in server's JOIN command reply in
7419 silcd/command_reply.c
7421 * Fixed braodcasting of replace ID payload to not to send it if
7422 we are standalone server in silcd/packet_receive.c.
7424 * Fixed all channel message sending routines to not to send
7425 packets to clients that has router set, since they are routed
7426 separately in the same function earlier. Affects file
7427 silcd/packet_send.c and all channel packet sending functions.
7429 * In USERS reply, res_argv[i] are not allocated, the table
7430 is allocated. Thus changed that free the table, not its
7433 * In server's whois_check and identify_check if the client is
7434 locally connected do not send any WHOIS commands - they are not
7437 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7439 * Fixed some minor bugs in client when sending WHOIS command. The
7440 arguments was in wrong order.
7442 * Removed statis function add_to_channel from server in
7443 silcd/command.c that was previously used with the joining but
7446 * Tested USERS command in router environment successfully with two
7447 routers, two servers and two clients.
7449 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7451 * Reorganized the USERS command and command reply in client library
7452 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
7453 When the command is given by user we register a pending command
7454 callback that will reprocess the command after the reply has been
7455 received from the server. When reprocessing the packet we then
7456 display the information. Thus, the USERS information is displayed
7457 now in the command callback instead of in the command reply
7458 callback. The processing of the command is same as previously
7459 when server has sent the command reply in the JOINing process.
7461 * Added to USERS command in silcd/command_reply.c to join the client,
7462 we didn't use to know about, to the channel after we've created
7463 a client entry for it. Also, for clienet we did know already still
7464 check whether it is on the channel or not and add it if not.
7466 * Removed silc_server_command_join_notify as the function and its
7469 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7471 * Changed the client's pending command handling to the same as the
7472 server's pending command handling. It is also now possible to
7473 execute command reply functions from other command reply
7474 function as the function callbacks for commands and command
7475 replies are one and same. The pending commands are not static
7476 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
7477 in client connection context. Thus, pending commands are server
7478 connection specific as it is convenient.
7480 Changed the function silc_client_command_pending and
7481 silc_client_command_pending_del and added new function
7482 silc_client_command_pending_check. Removed the
7483 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
7486 * Added cmd_ident, current command identifier, to the client
7487 connection context in lib/silcclient/client.h to keep track on
7488 command identifiers used in command sending. Client's command reply
7489 function handling now supports the mandatory command identifiers.
7491 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
7492 funtions in client to fully support pending command callbacks.
7494 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
7495 as one of the arguments to the application in the command reply
7498 * NOTE: The FORWARDED flag is depracated. It used to be depracated
7499 before first releasing SILC but came back. Now it is removed again
7500 and should come back nomore. The FORWARDED flag was used only
7501 by the JOINing procedure by forwarding the command packet to router.
7502 Now, the JOINing procedure has been changed to more generic (due
7503 to various router environment issues) and FORWARDED is not needed
7504 anymore for anything. The protocol specification is yet to be
7507 Now, removed silc_server_packet_forward from server and the flag
7508 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
7510 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7512 * Renamed NAMES command to USERS command. The NAMES was named that
7513 due to historical reasons. Now it is renamed. Also, rewrote
7514 parts of the USERS command. The nickname list is not sent anymore
7515 by the server. Only Client ID and mode lists are sent in the USERS
7516 command. Changed this also to the protocol specification.
7518 The client now resolves the names and stuff after it receives
7519 the USERS list from the server when joining to the channel.
7521 * WHOIS and IDENTIFY commands has been changed to support multiple
7522 Client ID's per command. One can now search for multiple users
7523 in the network by sending only one WHOIS or IDENTIFY command.
7524 Changed the code and the protocol specifications.
7526 * Removed silc_server_command_identify_parse and changed that IDENTIFY
7527 uses silc_server_command_whois_parse to parse the request. */
7529 * If normal server, do not parse the WHOIS and IDENTIFY requests
7530 before sending it to the router. Saves some time.
7532 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7534 * Fixed JOIN command on client library. Wrong number of arguments
7535 used to crash the client.
7537 * Added silc_server_channel_has_global function to check whether
7538 channel has global users or not.
7540 * Added silc_server_channel_has_local function to check whether channel
7541 has locally connected clients on the channel.
7543 * The silc_server_remove_from_one_channel now checks whether the
7544 channel has global users or not after given client was removed from
7545 the channel. It also checks whether the channel has local clients
7546 on the channel anymore. If it does not have then the channel entry
7547 is removed as it is not needed anymore.
7549 * The silc_server_notify now checks on JOIN notify whether the joining
7550 client is one of locally connected or global. If it is global then
7551 the channel has now global users on the channel and that is marked
7552 to the channel entry. Also, it now saves the global client to
7553 global list who is joining and JOINs it to the channel. This is
7554 for normal server, that is.
7556 Changed silc_server_send_notify_on_channel,
7557 silc_server_packet_relay_to_channel and
7558 silc_server_packet_send_to_channel check if we are normal server
7559 and client has router set (ie. global client) do not send the
7560 message to that client, as it is already routed to our router.
7562 * Implemented LEAVE notify type handling in silc_server_notify
7565 * Tested LEAVE command in router environment successfully. Tested
7566 with two routers, two servers and two clients.
7570 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
7572 * Implemented SIGNOFF notify type handling in silc_server_notify
7575 * silc_server_remove_id now removes the client entry from all channels
7576 it has joined and thusly sends SIGNOFF notify type.
7578 * Rewrote the NAMES list generation in server by removing two excess
7579 loops. The lists are created now inside one loop.
7581 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7583 * silc_server_remove_channel_user checks now also global list
7584 for channel and client.
7586 * silc_server_new_channel_user checks now both local and global
7587 list for channel and client. Fixed a bug in client id decoding.
7588 Used to decode wrong buffer.
7590 * silc_server_channel_message checks now both local and global
7591 list for channel entry.
7593 * Tested channel joining (hence JOIN) in router environment
7594 successfully. Tested with two routers, two servers and two
7597 * Tested channel message sending in router environment successfully.
7599 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7601 * Added silc_server_save_channel_key into server.[ch] to save the
7602 received channel key in Channel Key payload processing. It is
7603 also used in JOIN command reply handling.
7605 Equivalent function silc_client_save_channel_key added into
7606 client.[ch] into client library.
7608 * Changed JOIN command reply to send information whether the channel
7609 was created or not (is existing already) and the channel key
7610 payload. Changed protocol specs accordingly.
7612 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
7613 the request was sent by ID and not by nickname. Crashed on
7616 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7618 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
7619 now correctly save the received data.
7621 * silc_server_free_sock_user_data now notifies routers in the
7622 network about entities leaving the network.
7624 At the same time implemented functions silc_server_remove_id
7625 and silc_server_send_remove_id to receive and send REMOVE_ID
7626 packets. The packet is used to notify routers in the network
7627 about leaving entities. The ID removed will become invalid in
7630 * Added function silc_idlist_del_server into server. Removes and
7631 free's server entry from ID list.
7633 * silc_server_private_message function now checks, if we are router,
7634 that the destination ID really is valid ID, naturally.
7636 * In router when NEW_ID packet is received (for new client) the
7637 hash of the Client ID is saved in the ID Cache but the
7638 client->nickname is set to NULL, instead of putting the hash
7641 IDENTIFY command now also checks that client->nickname must be
7642 valid. If it is not if will request the data from the server who
7643 owns the client. Added new function
7644 silc_server_command_identify_check.
7646 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
7647 to set the command to already allocated Command Payload.
7649 * Tested private message sending in router environment with two
7650 routers, two servers and two clients. Fixed minor bugs and now
7653 * Fixed segfault from client's NAMES command. Used to crash if
7656 * Forwarded packets must not be routed even if it is not destined
7657 to the receiver. Changed server code comply with this.
7659 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7661 * Added `require_reverse_mapping' boolean value to ServerParams
7662 structure. If TRUE (not default) the server will require that
7663 the connecting host has fully qualified domain name.
7665 If the reverse mapping is not required and hostname could not be
7666 found the IP address is used as hostname.
7668 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7670 * Implemented version string checking to both client and server.
7671 The check is incomplete currently due to the abnormal version
7672 strings used in development version of SILC.
7674 * Changed all command functions in server to use the new
7677 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7679 * Changed char *data to unsigned char *data in ID Cache system to
7680 support binary data as ID Cache data. Changed code to support
7681 binary data in lib/silccore/idcache.c.
7683 * Renamed silc_server_packet_relay_command_reply to
7684 silc_server_command_reply as it is normal packet receiving
7685 function. Rewrote the function to accept command replys for
7686 servers and not only for clients.
7688 * Mark remote router always as registered server if we are connecting
7689 to it. Otherwise, commands sent by the router to us are ignored.
7691 * All ID List find routines now returns the ID Cache Entry pointer
7692 as well if requested.
7694 * WHOIS command works now in router environment, tested with two
7695 routers, two servers and two clients.
7697 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
7698 in router environment (as it is almost equivalent to WHOIS) but
7699 hasn't been tested thoroughly. Added new functions:
7701 silc_server_command_identify_parse
7702 silc_server_command_identify_send_reply
7703 silc_server_command_identify_from_client
7704 silc_server_command_identify_from_server
7706 * Disabled route cache adding because adding two different ID's with
7707 same IP replaces the old cache entry thus giving wrong route.
7708 The entry->router->connection is always the fastest route anyway
7709 so route cache may not be needed. Of course, new routes maybe
7710 established after receiving the ID when the entry->router->connection
7711 might not be anymore the most optimal.
7713 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7715 * Add route cache for received ID for fast routing.
7717 * Added silc_server_packet_route to route received packet on router
7718 that is not destined to us.
7720 * Renamed silc_server_get_route to silc_server_route_get.
7722 * Added id_string and id_string_len fields into SilcServer to
7723 include encoded ServerID for fast comparing without excess
7724 encoding of the ID's.
7726 * Cleaned up WHOIS command on server side. Added following static
7729 silc_server_command_whois_parse
7730 silc_server_command_whois_check
7731 silc_server_command_whois_send_reply
7732 silc_server_command_whois_from_client
7733 silc_server_command_whois_from_server
7735 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
7736 arguments in command replies. All command functions should be
7737 updated to use this macro.
7739 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7741 * Minor typo fixes on command reply handling on server.
7743 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7745 * Added silc_server_command_add_to_channel internal routine to add
7746 the client to the channel after router has created the channel and
7747 sent command reply to the server.
7749 * Added generic silc_server_send_command to send any command from
7752 * Use static buffer with ID rendering instead of duplicating data.
7754 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7756 * Fixed a channel user mode bug when joining to a channel server gave
7757 everybody channel founder rights, oops.
7759 * We mark ourselves as the router of the incoming server connection
7760 if we are router ourselves. This way we can check in some packet
7761 sending functions whether it is locally connected server. For
7762 incoming router connections we put NULL.
7764 * For router sending packets locally means now always sending the
7765 packet cell wide; to local clients and local servers. For normal
7766 server sending packet locally means sending it to only local
7769 * Fixed the JOIN command to really work in router environment. If the
7770 channel is created it is always created by the router. Router is
7771 also responsible of making the initial joining to the channel,
7772 sending JOIN notify to the sending server and distributing
7773 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
7774 does not exist server doesn't do anything else but forward the
7775 command to the router which performs everything.
7777 * Added silc_server_send_channel_key function to send the Channel Key
7780 * Added silc_server_create_channel_key to create new channel key. The
7781 channel key is now re-generated everytime someone joins or leaves
7782 a channel, as protocol dictates. Note: channel->key_len is the
7785 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7787 * Splitted server.[ch] finally. Created now packet_send.[ch] and
7788 packet_receive.[ch] to separate packet sending and receiving
7789 routines. The server.[ch] now includes everything else including
7790 actual packet processing (writing and reading data) and other
7793 Renamed silc_server_private_message_send_internal to
7794 silc_server_send_private_message. The routine is still though
7795 used only to relay private messages as server does not send
7796 private messages itself.
7798 Renamed silc_server_new_channel to silc_server_create_new_channel
7799 and added new function sicl_server_new_channel that handles the
7800 incoming New Channel packet. Added also new sending function
7801 silc_server_send_new_channel to send New Channel Payload.
7803 * Added new function silc_server_notify to process incoming notify
7804 packet to the server/router. Server may then relay the notify
7805 to clients if needed.
7807 * Added new function silc_server_new_channel_user to process incoming
7808 New Channel User packet. Router will redistribute the packet and
7809 send JOIN notify to its local clients and locally connected servers
7810 if needed. Normal server will send JOIN notify to its local client
7811 on same channel when received this packet. Added also corresponding
7812 sending function silc_server_send_new_channel_user to sent the
7815 * Added boolean route argument to send_notif_to_channel and
7816 packet_send_to_channel functions to attempt to route the packet
7817 if it is TRUE and send only locally if it is FALSE.
7819 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7821 * silc_server_replace_id now broadcasts the received replace ID
7822 packet if it is not broadcast packet already. The router must
7823 broadcast to inform other routers about changed ID.
7825 * Added backpointer to server's router into SilcServer context in
7826 silcd/server_internal.h.
7828 * Fixed silc_server_packet_broadcast to send correct broadcast
7831 * The channel key is now distributed to the local client as soon
7832 as it is received from the router (in router environment) so that
7833 no other packet may be sent for the channel until client has
7836 * silc_server_remove_channel_user now broadcasts the received
7837 Remove Channel User packet if it is not broadcast packet already.
7838 The router must broadcast to inform other routers about removed
7841 * Added users field into SilcPacketContext that is a reference count
7842 of the context. One can increase the reference count by calling
7843 silc_packet_context_dup which is now changed to just increase the
7844 reference count instead of duplicating the data. The reference
7845 count is decresed by calling silc_packet_context_free that will
7846 free the data after the reference count hits zero.
7848 For now on the packet context and everything allocated into it
7849 (including the raw packet from network) must be freed by calling
7850 the new silc_packet_context_free function. Added also new function
7851 silc_packet_context_alloc that must be used now to allocate the
7852 context. This also means that if a routine is asynchronous from
7853 silc_[client/server]_packet_parse_type the packet context must
7854 be duplicated by calling silc_packet_context_dup. Otherwise it
7855 gets free'd after silc_[client/server]_packet_parse_type returns.
7856 Also, one must remember that if packet is duplicated then its
7857 reference count must be decresed by calling the free function as
7858 many times as it was duplicated.
7860 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7861 from both client and server.
7863 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7865 * Made joining to a channel working in router environment.
7867 * Cleaned up JOIN command on server side and create function
7868 silc_server_command_join_channel internal routine to make the
7871 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7873 * Changed silc_command_pending list to SilcDList. Also, added
7874 `ident' field to SilcServerCommandPending structure to identify
7875 the reply and to call correct callback.
7877 Added silc_server_command_pending_check function to replace the
7878 corresnponding macro. The silc_command_pending list is not
7881 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7882 to set identifier to previously allocated Command Payload. It
7883 is used to set identifier for command when resending Command
7886 * Added silc_command_payload_encode_payload to encode Command
7887 Payload buffer from SilcCommandPayload structure.
7889 * Added silc_argument_payload_encode_payload to encode Argument
7890 payload buffer from SilcArgumentPayload structure.
7892 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7894 * Changed WHOIS command to support router connection on server side.
7895 The whois request is always sent to router unless the server is
7896 standalone server. After server has received the reply from the
7897 router will it send the reply to the client.
7899 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7900 broadcast received broadcast packet. The function is used only
7901 by router. The broadcast packet is always sent to the router's
7904 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7905 render given ID to printable string, for log files for example.
7907 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7909 * Made basic router to router connections working. At least they
7910 can now connect to each other but nothing really works the way
7911 they are supposed - yet.
7913 * Added new initiator token to RouterConnection configuration
7914 file in silcd/serverconfig.[ch]. It is used to tell whether we
7915 are the initiator to the remote router or whether we'll expect
7916 the other end to connect.
7918 * Moved registering of listener task to silc_server_init, hence
7919 the server starts listenning as soon as it is run, even if it
7920 does not have connections to other routers. Let's see how well
7923 * Changed default connection retry timeouts for more suitable in
7926 * Removed cipher and such arguments from silc_idlist_add_client
7927 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7928 Added new function silc_idlist_add_data to add the keys and stuff
7931 * Added SilcIDListData structure and added it to SilcClientEntry
7932 and SilcServerEntry as their first field in the structure. This
7933 way we can explicitly cast the ID entries to the SilcIDListData
7934 structure and get common data for the entries. In past, we had
7935 to first check what type of connection it is and then cast it to
7936 correct ID entry type. Now, we can directly cast the opaque
7937 pointer to the SilcIDListData (no matter what ID entry it actually
7938 is) and get the data needed.
7940 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7942 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7943 in some circumstances even if threre were timeout tasks, though not
7944 IO tasks, but tasks anyway. Now fixed.
7946 * Defined SilcServerConnection structure to hold connection specific
7947 stuff about directly connected servers and routers. The definition
7948 is currently in silcd/server_internal.h. I thought about having
7949 a bit more important role fro this struct but for now it is used
7950 only when connecting to other server (or router actually).
7952 * Added connecting retry support in server when connecting to
7953 router(s). The retry feature implement exponential backoff
7954 algorithm. Also, added SilcServerParams structure to hold default
7955 parameters for server. For now, it include these retry settings
7956 and are hard coded. After server is moded to be as Silc Server
7957 Library this structure will be more important.
7959 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7961 * Changed client librarys channel->clients table to SilcList and
7962 changed code accordingly.
7964 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7966 * Changed client's channel table to SilcList and changed code
7967 accordingly. Also changed SilcChannelClientEntry to include back-
7968 pointer to the channel so that client entry can use that structure
7969 as list as well and we have fast cross-reference to the channel.
7970 This change dramatically decreased the complexity of channel
7971 handling with client entry and vice versa (removed one extra
7972 loop when searching for channel entry from many functions).
7974 * Changed server->sim from table to SilcDList and changed code
7977 * NAMES command can now be used from user interface. It will show
7978 the user list on the channel, neatly.
7980 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7981 Code now saves realname of the user if it becomes available.
7983 * Renamed configure.in to configure.in.pre and made ./prepare
7984 script to automatically add correct version string to
7985 configure.in which it creates from configure.in.pre.
7987 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7989 * NAMES command reply now shows users mode with the nickname when
7992 * Moved silc_client_ch[u]mode[_char] functions from
7993 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7994 place sucks, they are utility functions and should be in some
7997 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7999 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
8002 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8006 * Added TRQ (efficient deque and list library) into lib/trq. This is
8007 a very good list library that is currently used in the SILC. Defined
8008 SilcList API over the library because I didn't like the API very
8009 much. See lib/trq/silclist.h for the API and examples of how to
8010 use the API. Fixed various places in the code to use the new
8011 SilcList API. The SilcList is meant for lists that has a structure
8012 already defined as a list. It is not suitable to add just some
8013 context to the list (in TRQ, the context is the list actually).
8015 So, I defined SilcDList that can be used for the purpose where
8016 predefined list structure does not exit. This can be used as
8017 such list. Now some context just can be added to the SilcDList.
8018 Currently this list is not used in the SILC just yet, though there
8019 are a lot places where this can replace dynamically allocated
8020 tables and I will fix these places, later, to use SilcDList.
8021 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
8022 and use TRQ internally).
8024 Also fixed some annoying warning messages that the original TRQ
8025 code generated. Also minor changes to TRQ's Makefile.in.
8027 * Added support for querying by Client ID to both WHOIS and
8028 IDENTIFY commands into server, as required by the protocol.
8030 * Removed method function pointers from SilcBuffer structure. They
8031 weren't used to anything and just increased the context size for
8032 no good reason. This change also made silc_buffer_alloc and
8033 silc_buffer_free functions inline functions.
8035 * Disabled command flooding detection support until it's fixed so
8036 that it accepts commands in but does not execute them more than once
8039 * Added silc_net_localhost(), to return local hostname, into
8040 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
8041 that must be initialized before calling silc_client_init.
8043 * Added new function: silc_server_send_notify_on_channels to send
8044 notify messages to all channels client has joined. It is assured
8045 that the message is sent only once per client.
8047 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
8048 lib/silcutil/silcutil.[ch] as silc_format function. The new
8049 function is generic and is used by server as well, not only by
8050 the logging routines.
8052 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
8053 the provided version string was not acceptable. Added new function:
8054 silc_ske_check_version into lib/silcske/silcske.h. The function
8055 must be implemented by the application (client or server) and it
8056 does not reside in the SKE library. The function checks the version
8057 string remote end sent.
8059 * Added back pointers (to opaque context and to SilcSocketConnection)
8060 into SilcPacketContext structure into lib/silccore/silcpacket.h.
8062 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
8063 duplicate packet context structure.
8065 * Changed `notify' client operation to send same arguments as client
8066 receives from server except for ID's. ID's are mapped to correct
8067 ID entry and that is returned. Also, if channel entry is not sent
8068 by server but the notify is for channel the channel entry is sent
8069 to application (otherwise application doesn't know that it is for
8070 channel (library gets it from packet's Destination ID)).
8072 * Added silc_client_remove_from_channels into client library to
8073 remove a client from all channels it has joined to. Used when
8074 received SIGNOFF notify from server. Added also new function
8075 silc_client_replace_from_channels to replace old ID entry with
8076 new ID entry on all channels. Used when received NICK_CHANGE
8079 * Fixed ID Cache list handling in silc_idlist_get_client in
8080 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
8081 to get (or query) client by ID.
8083 * Updated TODO list.
8085 * Added connection authentication status message defined by the
8086 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
8087 support for these into the code in client and server side.
8089 * Added generic function silc_client_send_command to send any command
8090 with variable argument list. Application should use this function
8091 to send commands if the command functions provided by the library
8092 does not suite for the application's user interface needs.
8094 * Added new `failure' client operation. Application is notified about
8095 received failure packet if client is executing a protocol. In this
8096 case the protocol's execution has failed.
8098 * Added SKE's end notify to send the SKE_SUCCESS notify message that
8099 is required by the protocol.
8101 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
8102 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
8105 * Added status flag to SilcSKE object to indicate realtime status
8106 of the SKE protocol.
8108 * Application receives now exactly same command reply arguments as
8109 the library receives from server. However, if ID is received the
8110 corresponding ID entry is returned to the application (eg. Client
8111 ID is mapped to correct SilcClientEntry entry and that is returned).
8112 Changed command_reply client operation due to this change.
8114 * Changed all ID's in commands and in command replys as ID Payloads.
8115 Change affected both client and server side codes.
8117 All ID's sent in SILC network (with execption of ID's in SILC
8118 Packet header) are sent in ID Payload to support variable length
8121 * Server now notifies nick changes and notifies all clients on
8122 the channels about the new nickname (about the new Client ID,
8125 * Implemented CMODE command to change channel modes. Supports all
8126 channel modes defined by the protocol specs except ban and invite
8127 lists. (Also, private channel key mode is supported but support for
8128 setting private channel key in client is missing, thus, this mode
8129 has no effect on client side (except that server requires that the
8130 client uses private channel key and normal channel traffic does not
8133 Also, invite mode works per se, but INVITE command does not work
8134 yet correctly, so you can set channel as invite only channel but
8135 inviting clients to the channel does not work (it is yet to be
8136 thought what's the best way to do it).
8138 * Added new command SILC_COMMAND_CUMODE to change user mode on the
8139 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
8140 Implemented CUMODE command to change user's mode on the channel.
8141 Supports all modes defined by the protocol specs.
8143 * Added NAMES command reply to return users modes on the channel.
8145 * Removed unnecessary and slow ciphers from lib/silccrypt.
8147 * Set SO_KEEPALIVE option to connection sockets by default.
8149 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
8151 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
8152 redefined the Notify Payload into protocol specs.
8154 * Added silc_id_payload_parse_id to get ID directly from raw
8157 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8159 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
8160 accept searching by Client ID as well.
8162 * Added support for LEAVE and SIGNOFF notify types in client library.
8164 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
8165 to parse ID Payload from raw data.
8167 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8169 * Added flags parameter into silc_ske_assemble_security_properties
8170 function in lib/silcske/silcske.[ch].
8172 * Changed notify client operation to fit better for notify messages
8173 sent by server. The notify payload received from server is now
8174 passed to the application (after parsing it to SilcNotifyPayload).
8175 It is application's responsibility to retrieve the arguments
8176 from the payload and show the message the way it wants. The message
8177 sent by server is implementation specific.
8179 * Changed public keys to comply with the protocol specification.
8180 Old public keys are not supported anymore and are not compatible.
8182 * Removed nickname from Channel Payload as the latest draft removed
8183 it. The client must resolve the nickname from the NAMES command
8184 reply received when it joined the channel.
8186 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
8188 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8190 * Fixed some errors in protocol specification drafts.
8192 * Created lib/silccore/silcnotify.c to implement Notify Payload
8193 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
8194 generic payloads described by protocol specifications. The file
8195 includes implementations for ID Payload and Argument Payload.
8197 * Changed Command Payload implementation to use the new Argument
8198 Payload. Changed command_xxxx_payload to command_payload_xxxx
8199 to comply with SILC coding conventions.
8201 * Added suppport for Argument Payload handling in Notify Payload
8202 implementation as protocol requires it. Added the new support
8203 into server and client lib as well.
8205 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8207 * Added support for multiple nicknames on same channel. [n] is
8208 added locally to the nickname if there are more than one same
8209 nicknames on the channel.
8211 * Server now sends all nicknames that matched WHOIS request.
8212 Client also shows the list received from server.
8214 * Added TOPIC command to client side. User can now set and show
8215 current topic on channel.
8217 * Added MOTD command to client and server. Also, server sends the
8218 motd when client connects to the server.
8220 * Changed version strings to comply ISO 8601.
8222 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8224 * Fixed protocol error handling in client library. It should now
8225 cope even if the SKE fails for some reason.
8227 * Made new protocol specification drafts for submitting to IETF.
8229 * Implemented TOPIC command to server in silcd/command.c.
8231 * Added two new notify types into lib/silccore/silcnotify.h:
8232 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
8233 notify nickname change and topic setting/change on a channel.
8235 * API change of command_reply operation in client library. The
8236 application gets now the status type received from server as well.
8238 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8240 * Removed the function just added to lib/silcutil/silcschedule.[ch].
8242 * Cras fixed and optimized the packet handling even further and
8243 it should work now. Minor change to the prototype of function
8244 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
8246 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8248 * Added new function into lib/silcutil/silcschedule.[ch]:
8249 silc_schedule_with_fd to select() a specified fd. The function
8250 returns after timeout expires or data arrives or goes. The
8251 function is used by packet routines to wait that all data is
8252 received from network.
8254 * Fixed data reading from network in lib/silccore/silcpacket.c.
8255 The code now assures that all data is read from the fd and then
8256 continues packet processing. This was a bug fix since the code
8257 used to drop some data in some circumstances.
8259 * Added new function into lib/silcclient/client.[ch]:
8260 silc_client_start_key_exchange to start key exchange after
8261 connection has been established to server. The code internally
8262 now uses this funtion but its main purpose was to provide it
8263 for applications that perform their own connecting. After
8264 application has created a connection it merely calls this
8265 function to start the key exchange between client and server.
8266 The library takes care of everything else after that.
8268 Updated also lib/silcclient/README to explain the usage of
8271 * Do not send to application information that connection has
8272 been established. Application gets notified it by connect
8275 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8277 * Applied cras's patch to add silc_schedule_one function. The
8278 function runs scheduler once and returns.
8280 * Fixed the scheduler after cras messed it up. The timeout
8281 handling works now as it's supposed to work.
8283 * Added into lib/silccore/ silcnotify.h to include notify
8284 message types support. Changed silc_server_send_notify*
8285 functions, in server.[ch], to support those new notify types.
8286 Added the support for the notify types into client library,
8287 as well. Added new notify client operation into ops.h in
8290 * Changed silc_server_packet_send_to_channel to send normal
8291 packets instead of just channel message packets. The function
8292 is now used to send the notify packets to channels. It is not
8293 used to send channel message packets anymore, as server never
8296 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
8297 va_arg()s as it seems to require it nowadays. I guess, if SILC
8298 is compiled with older va_arg() the new code should work anyway.
8300 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8302 * Splitted core library. Core library (lib/silccore) includes
8303 now only SILC protocol specific core (and common) components.
8304 Created new utility library (lib/silcutil) that includes more
8305 generic purpose stuff. The stuff for util library was taken
8306 from the old core library. This was minor and easy split.
8308 * Created SILC Client Library (lib/silcclient) that includes
8309 implementation of the SILC client without user interface. This
8310 was major move from silc/ directory. The code has been changed
8311 so that it is transparent towards the user interface. The
8312 silc/ directory includes now the same user interface as before
8313 and it uses the new client library. Read lib/silcclient/README.
8314 Basicly, the client library performs everything else related
8315 to SILC except user interface handling. Also, configuration
8316 files are considered to be part of user interface and library
8317 does not handle them.
8319 This change also changed a lot of structures, function naming etc.
8320 Most important change was that SilcClientWindow object was
8321 renamed to SilcClientConnection in the client library. Created
8322 also new file lib/silcclient/ops.h. Also added new files
8323 silc/local_command.[ch] and silc/client_ops.[ch].
8325 All these changes were made to make it easier for user interface
8326 designers to create what ever user interface for the SILC client
8329 It is also expected that the server will be moved to lib
8330 directory as well and SILC Server Library will be created;
8331 sometimes in the future.
8333 * Removed Local commands from lib/silccore/silccommand.h as
8334 they are application specific and new client library does not
8335 handle any of those anymore.
8337 * Several functions moved to lib/silcutil/silcutilc.[ch] from
8338 old client implementation in silc/.
8340 * Added support for callback functions in SILC_LOG_* macros.
8341 Application can now set its own callbacks that will be called
8342 instead of using the default functions that will always print
8343 the debug messages to stderr (or stdout). Also, debugging can
8344 now be disabled by setting silc_debug to FALSE and re-enabled by
8345 setting it to TRUE. Note, that logging will still work even
8346 if debugging is disabled.
8348 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
8349 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
8350 silc_log_reset_debug_callbacks.
8352 * To enable debugging in silc client one must give now -d
8353 option on command line.
8355 * Changed silc_schedule_init to automatically allocate task queues
8356 if they are not allocated before calling it.
8358 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8360 * Added GMP 3.1 into math library.
8362 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8364 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
8365 a channel in SILC network. The packet is used by servers and
8366 routers to notify other routers that user has left a channel.
8367 This little feature was missing until now. Added the feature
8368 to protocol specification as well.
8370 Added functions: silc_server_send_remove_channel_user and
8371 silc_server_remove_channel_user into server.[ch].
8373 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
8374 lib/silccore/silcpacket.h. However, they are not implemented
8377 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8379 * Fixed joining to a channel and sending channel messages
8380 between server and router. The channel message sending should
8381 now work inside a cell.
8383 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8385 * Fixed the private message sending between server and router.
8386 The private message sending should now work inside a cell.
8388 * Added silc_server_replace_id into server.[ch] to replace
8389 existing ID in the SILC network.
8391 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
8392 and silc_idlist_replace_server_id into idlist.[ch] in server.
8394 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8396 * Fixed the server to server connections. Server can again now
8397 connect to router. Router to router connections probably does
8400 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8402 * Added dynamic protocol registering support. Now protocols can
8403 registered and unregistered on the fly. Patch by cras.
8405 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8407 * Added lib/contrib directory to hold routines that some platforms
8408 don't have but are needed by SILC.
8410 * Added getopt.c, getopt1.c and getopt.h from GNU C library
8411 into lin/contrib to provide getopt() and getopt_long() for
8412 those who don't have it.
8414 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8416 * Added AWAY command to client. When away message is set and
8417 client receives a private message packet the client automatically
8418 replies to the sender with the away message.
8420 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
8421 bug seemed to be the cause of recent problems when compiling
8424 * Added version detection support to SKE protocol specification
8425 and added the new changes to the SKE implementation as well.
8426 There were other minor changes in the SKE protocol as well.
8428 Many changes in lib/silcske/silcske.[ch] and in
8429 lib/silcske/payload.[ch].
8431 * Added ^U functionality, clear input line. Patch from cras.
8433 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8435 * Mainly small bugfixes on core library. Fixed some debugging
8436 logging and buffer overflow in silclog.c.
8438 * Updated config.sub and config.guess on the distribution tree.
8440 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8442 * Added command lagging support in server. Client may execute
8443 commands now only once in two seconds.
8445 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8447 * Optimized packet reception. MAC computation and checking is now
8448 also more optimized. A lot previously duplicated code is now
8449 used as generic by both client and server.
8451 * Fixed key pair generation in clientutil.c
8453 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8455 * Added into lib/silccore/silcbufutil.[ch] new function;
8456 silc_buffer_realloc.
8458 * Moved generic packet sending/encryption functions to
8459 lib/silccore/silcpacket.[ch] from client and server. Some
8460 rewriting of the functions.
8462 * Moved all generic packet reception/decryption functions to
8463 lib/silccore/silcpacket.[ch] from client and server. The
8464 packet processing is now much cleaner in both client and server.
8465 These were major changes in both client and server.
8467 * Created many common functions in server to do packet sending.
8468 Previously code were duplicated a lot, this has been removed
8471 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8473 * Rewrote major parts of the ID cache system. Don't know
8474 whether it is better now or not but at least the API is more
8477 * Major rewrite on ID cache stuff on client because of the ID
8478 cache API changes. Added idlist.c to client.
8480 * Also major rewrite on ID cache stuff on server as well.
8481 Major rewrite of idlist.[ch]. SilcXXXList's are now named
8482 SilcXXXEntry's. We won't keep anymore idlist specific pointers
8483 in hand, instead they are all put into the ID cache system now.
8484 All server_idlist_* routines uses ID cache now instead of
8485 traversing its own lists (those lists does not exist anymore).
8486 SilcIDList though still exists. Also, SilcXXXEntry's are
8489 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8491 * Finally made the SKE implementation compliant to the protocol
8492 specification. All mp integers are now binary encoded as
8493 opposed being HEX encoded.
8495 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
8498 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
8499 functions: silc_[encode/decode]_pem. Also added function
8500 silc_encode_pem_file to PEM encode with newlines ('\n') for
8503 * SILC public keys are now encoded either PEM or binary. Same
8504 option is for private keys as well. By default private keys
8505 are binary encoded and public keys PEM encoded. Silly HEX
8506 encoding were removed.
8508 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
8509 function to create fingerprints.
8511 * Fixed a bug in SHA1; does not change the original data anymore.
8513 * Partly implemented INFO command on client and server side.
8514 Fixed CLEAR command. Changes to SERVER command; show current
8515 server(s) when giving command without arguments. Added
8516 VERSION command to client.
8518 * Added check to server that unregistered connections cannot
8519 execute commands (unless it is specificly allowed).
8521 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8523 * Fixed screen refresh.
8525 * Fixed channel joining bug from client. On some circumstances
8526 client tried to join to a channel it had already joined.
8528 * Added public key verification process into client's protocol.c.
8529 The client now verifies the public key from user and saves
8530 it into ~./silc/serverkeys/ directory.
8532 Added into: clientutil.[ch]: silc_client_verify_server_key.
8534 * Changed SKE protocol's silc_ske_initiator_finish function
8535 to accept callback function that verifies the received public
8536 key. Removed old silc_ske_verify_public_key function.
8538 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8540 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
8541 silc_pkcs_private_key[_data]_set.
8543 * Made the password and public authentication more cleaner in
8544 server's protocol.c.
8546 * Removed historic and obsolete protocol `channel_auth' from
8547 both client and server.
8549 * Removed wrong way of sending command status messages from
8550 server to client in server's command.c. The old way violated
8551 protocol specification.
8553 Changes to silccore/silccommand.[ch]: removed
8554 silc_command_encode_status_payload -> not needed anymore,
8555 changed silc_command_encode_payload_va to accept extra
8556 argument on variable argument list. The argument type must
8557 now be provided to the function. Also, added new function:
8558 silc_command_encode_reply_payload_va which is same as
8559 normal command_encode_payload_va except command status type
8560 is provided as extra argument.
8562 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8564 * Added ~./silc directory handling. The directory includes the
8565 public and private keys for the client.
8567 Added silc_client_check_silc_dir, silc_client_create_identifier
8568 and silc_client_load_keys.
8570 * Implemented SILC protocol compliant public key. Added public
8571 and private key saving to and loading from files.
8573 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
8574 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
8575 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
8576 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
8577 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
8579 Implemented: silc_pkcs_save_[public/private]_key[_data] and
8580 silc_pkcs_load_[public/private]_key.
8582 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8584 * Added silc_server_get_route (route.[ch]) to get connection
8585 data for the fastest route for given ID.
8587 * Implemented INVITE command on client and server. The command
8588 were re-defined in the SILC Protocol Specification and the
8589 implementation now complies with the specification.
8591 * Implemented PING command on client and server.
8593 * Implemented NAMES command on client and server. The server side
8594 supports currently only normal server not router server yet.
8595 Some changes to NAMES definition in SILC protocol specification.
8597 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8599 * Implemented LEAVE command on client and server.
8601 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
8602 again. This change was made to the protocol as well. Server
8603 should not violate the protocol specification anymore.
8605 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8607 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
8608 was tested. SOCKS4 was not but should work anyway.
