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

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

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

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

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

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

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

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

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

990 allowed by the client. Affected file silcd/packet_receive.c.
992 * Created function silc_get_input which can be used to get input
993 (echo on or off) from user on command line. Affected files are
994 lib/silcutil/silcutil.[ch].
996 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
998 * Optimized silc_server_packet_relay_to_channel function.
999 Added new function silc_channel_message_payload_encrypt which
1000 can be called directly if channel message payload needs to
1001 be encrypted and is already encoded (no need to call _encode
1002 function). Packet relaying is now done by router without any
1003 extra memory allocations. Affected files are
1004 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
1005 silcd/packet_send.c.

1025 by the client. Affected files are silcd/server_util.[ch],
1026 silcd/packet_receive.c and silcd/command.c.
1028 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1030 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
1031 ID length. It ignored that ID can be IPv6 based as well.
1032 Affected file lib/silccore/silcpacket.h.
1034 * Fixed the silc_id_id2str and silc_id_str2id to take the
1035 IPv6 address offset's into consideration. Affecte file is

1041 NULL context they may receive. The affected file is
1042 lib/silcutil/unix/silcunixschedule.c.
1044 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
1046 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
1047 can specify different directory with --home command line
1048 parameter. Affected files irssi/src/silc/core/client_ops.c,
1051 * SILC-specific commands aren't now executed if the active server
1052 isn't of SILC-type, so there won't be problems with having
1053 IRC and SILC protocol support in same client. Affected files
1054 irssi/src/silc/core/silc-channels.c, silc-servers.c,
1057 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1059 * Improved the signal support in SILC Schedule. Added new
1060 function silc_schedule_signal_call which is used by application
1061 to mark a signal to be called. It is now safe to perform
1062 any kind of tasks in signal callbacks since it is guaranteed
1063 that the application specified signal callback is called
1064 after the signal is over. Affected files are
1065 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
1067 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1069 * Added `name' field to SilcChannelPrivateKey to represent
1070 application given name for the key. Moved also the context from
1071 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
1072 Added the `name' argument also to the function
1073 silc_client_add_channel_private_key.
1075 Added function silc_client_current_channel_private_key to set the
1076 current channel private key in use.
1078 Added "change" command to KEY command which can be used to change
1079 the current channel private key. Bound the command also to
1080 alt+K (Alt+Shift+k).
1082 Also affected files lib/silcclient/client_channel.c,
1083 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
1085 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1087 * Added silc_rng_get_byte_fast function in to the
1088 lib/silccrypt/silcrng.[ch].
1090 * Changed the interface of silc_packet_assemble and the
1091 silc_packet_send_prepare. If silc_packet_assmble is now
1092 called the application does not call silc_packet_send_prepare
1093 because the library will call it automatically. These
1094 interfaces now also return a reference to the outgoing buffer
1095 which includes the assembled packet, which the application can
1096 use to encrypt the packet.
1098 Affected files are lib/silccore/silcpacket.[ch],
1099 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
1100 silcd/packet_send.c, server_backup.c and packet_receive.c.
1102 * Fixed a packet sending bug on very high load, where outgoing
1103 packet queue wasn't handled correctly and packets got corrupted.
1104 Affected files are lib/silcutil/*/silc*sockconn.c,
1105 lib/silcclient/client.c and silcd/server.c.
1107 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1109 * Added macro SILC_PACKET_DATALEN which can be used during
1110 packet assembling to check whether the data to be added to
1111 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
1112 len is truncated until it fits it.
1114 Added checks for maximum length of channel message payload and
1115 private message payload also.
1117 Added checks for maximum packet length in server and in
1120 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
1121 lib/silcclient/client.c, lib/silccore/silcchannel.c and
1122 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
1123 lib/silcclient/client_prvmsg.c.
1125 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1127 * Added silc_server_packet_queue_purge call to the
1128 silc_server_disconnect_remote to assure that all data in the
1129 queue before disconnecting is sent to the network. Affected
1130 file silcd/server.c.
1132 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1134 * Added the deleting of server's own ID cache entry to the
1135 silc_server_free function. Free also everything else that
1136 has been allocated in silc_server_init. The affected file
1139 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1141 * Added functions silc_parse_version_string, silc_version_to_num,
1142 and silc_ske_parse_version to parse SILC protocol style version
1143 strings. Affected files lib/silcutil/silcutil.[ch] and
1144 lib/silcske/silcske.[ch].
1146 * Added new configuration params: version_protocol, version_software
1147 and version_software_vendor to specify what version the remote
1148 host must at least be to be able to connect to server. The vendor
1149 string can be regex matched too. Added new function
1150 silc_server_connection_allowed to check maximum number of allowed
1151 connections, and allowed versions for incoming connections.
1152 Affected files are silcd/server.c, server_util.[ch] and
1155 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1157 * Added preliminary support for signals in scheduler. The
1158 signals we care about are now blocked always when the scheduler
1159 is locked. This way we can synchronise the use of signal with
1160 scheduler. It is guaranteed that when signal occurs the scheduler
1161 is not locked, and thus new tasks can be safely added to the
1164 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
1165 to silc_schedule_internal_init and silc_schedule_internal_uninit.
1166 Added new platform specific routines
1167 silc_schedule_internal_signals_[un]block and
1168 silc_schedule_internal_signal_[un]register.
1170 Added new functions to SILC Schedule API:
1171 silc_schedule_signal_[un]register. Each signal that application
1172 is going to use should be registered to the scheduler.
1174 Affected files are lib/silcutil/silcschedule.[ch],
1175 lib/silcutil/*/silc*schedule.c.
1177 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1179 * Check for unauthenticated client and server in the
1180 silc_server_new_client and silc_server_new_server functions.
1181 Affected file silcd/packet_receive.c.
1183 * Added function silc_string_is_ascii to check whether given
1184 string is 7-bit ASCII string. Affected files are
1185 lib/silcutil/silcutil.[ch].
1187 * Added function silc_id_is_valid_server_id into the
1188 silcd/serverid.c and added checking for valid Server ID's in
1189 silc_server_new_server. The Server ID must always be based
1190 on the server's public IP address.
1192 * Added logging of DISCONNECT packet message in the server.
1193 Affected file silcd/server.c.
1195 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1197 * Changed all library interfaces that use Global RNG to also
1198 accept SilcRng as argument. Affected files are
1199 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
1200 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
1201 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
1202 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
1203 lib/silccrypt/rsa.c.
1205 * Added function silc_pkcs_generate_key to the
1206 lib/silccrypt/silcpkcs.[ch] for applications so that they
1207 don't need to do pkcs->pkcs->init calls anymore.
1209 * Remove SilcSocketConnection from the SFTP API since it really
1210 wasn't needed there. The application has the information
1211 saved in its contexts anyway and the SFTP layer doesn't need
1212 know about it. Affected files lib/silcsft/silcsftp.h and
1213 lib/silcsftp/sftp_[server/client].c.
1215 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
1216 The SilcSimContext is not SilcSim.
1218 * Fixed possible buffer overflows in silc_id_render in the
1219 lib/silcutil/silcutil.c.
1221 * On EPOC the global crypto module lists are not used at all
1222 in the crypto library. Added support for using the constant
1223 algorithm list on EPOC. Affected files are
1224 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
1227 * Fixed the handling of third parameter of KICKED notify, since
1228 it was mistakenly updated to SILC Protocol 1.0 even though it
1229 is to be included in 1.1. Since it is not in 1.0 it is not
1230 mandatory, and this fix now handles it only if it is provided,
1231 and it is not error if it is not provided. Affected file
1232 lib/silcclient/client_notify.c.
1234 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1236 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
1237 client. Affected file irssi/src/silc/core/client_ops.c.
1239 * Merged with Irssi 0.8.4 from irssi.org CVS.
1241 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1243 * Check for valid socket connection in client entries before
1244 sending any messages. Fixes a crash, but doesn't fix some
1245 other underlaying bug that is lurking there. Affected
1246 file silcd/packet_send.c.
1248 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
1250 * $usermode, $cumode and $cumode_space expandos shouldn't do
1251 anything with non-SILC server records. Affected file
1252 irssi/src/silc/core/silc-expandos.c
1254 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1256 * Fixed the silc_net_check_[host/local]_by_sock to support
1257 IPv6 bound sockets as well. Now they can return IPv6 addresses
1258 as well. Affected file lib/silcutil/silcnet.c.
1260 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
1261 Affected lib/silcutil/unix/silcunixnet.c.
1263 * Fixed ID rendering (at least on some platforms, not NetBSD)
1264 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
1266 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1268 * Added silc_hash_public_key and silc_hash_public_key_compare
1269 functions to be used with SilcHashTable. They can be used to
1270 hash public keys and compare public keys in hash table. Affected
1271 file lib/silcutil/silcutil.[ch].
1273 * Added support for specifying multiple public keys for Client
1274 connection section in server configuration file. This makes it
1275 possible to accept multiple public keys from same host, or to
1276 make a section that accepts any incoming host, and have the
1277 accepted public keys listed in the section.
1279 Added functions silc_sever_[find/get]_public_key, added the
1280 support for this actually to all connection sections but only
1281 the Client section is currently allowed to specify multiple
1284 Affected files are silcd/server.c, server_internal.h,
1285 command.c, protocol.c, server_util.[ch], packet_receive.c.
1287 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1289 * Merged Irssi 0.8.2 from irssi.org CVS.
1291 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1293 * If silc_debug is TRUE, also output standard logging messages
1294 to stderr with the debug output.
1296 Made silc_log_reset_all() flushing all channels before returning.
1297 Also fixed some documentation typos.
1299 Affected files are lib/silcutil/silclog.[ch].
1301 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1303 * Fixed the server to check correctly the amount of connections
1304 from single host, by checking also the type of the connection.
1305 Fixed also the comparison of number of connections and number
1306 of allowed connections. Affected files are silcd/server.c,
1309 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1311 * Fixed the USERS command reply to save the user's mode on the
1312 channel as well. Fixed JOIN command reply to check whether a
1313 client is on channel already and not join it twice. Affected
1314 file lib/silcclient/command_reply.c.
1316 * Added new file silc-expandos.c into irssi/silc/core/ to return
1317 various stuff for various signal for the statusbar etc. updating.
1318 Now Irssi SILC client prints channel user modes etc. on the
1321 * The user mode (like server/router operator changes) is now shown
1322 on the Irssi SILC client's statusbar. The affected files are
1323 irssi/src/silc/core/client_ops.c, silc-expandos.c.
1325 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1327 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
1328 to SILC_SCHEDULE_[UN]LOCK macros.
1330 * Added more error printing to logs in server code. Affected
1331 files silcd/server.c and silcd/protocol.c.
1333 * Fixed -S option parsing in Irssi SILC Client. Affected file
1334 irssi/src/silc/core/silc-core.c.
1336 * Added silc_buffer_alloc_size function. Affected file is
1337 lib/silcutil/silcbuffer.h.
1339 Tue Mar 5 14:37:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1341 * Changed all silc_[hash|hmac|cipher|pkcs]_default tables to
1342 constants. Affected files in
1343 lib/silccrypt/silcpkcs.[ch], silchash.[ch], silchmac.[ch] and
1346 * Changed the internal SFTP Memory FS table to const. Affected
1347 file lib/silcsftp/sftp_fs_memory.c.
1349 Sun Mar 3 18:37:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1351 * Fixed the buffer formatting and unformatting routines to
1352 check the size of 64 bits types with sizeof(). Affected
1353 file is lib/silcutil/silcbuffmt.c.
1355 Mon Feb 25 17:19:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1357 * Removed 0.6.x backwards support.
1359 Sun Feb 24 12:53:25 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1361 * Changed all integer type names:
1362 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
1363 to avoid collisions with other libraries using same type names
1366 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1368 * Added `prefer_ipv6' argument to the functions
1369 silc_net_gethostbyname[_async]. If it is TRUE it will return
1370 IPv6 address over IPv4. If FALSE IPv4 address is returned
1371 even if IPv6 address was found. Affected files
1372 lib/silcutil/silcnet.[ch].
1374 * Added support silc_net_create_connection[_async] to fallback
1375 to IPv4 address if IPv6 address could not be used (like if
1376 it doesn't work on a specific system). Affected file in
1377 lib/silcutil/unix/silcunixnet.c.
1379 Sat Feb 23 15:20:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1381 * Added silc_schedule_reinit function to do the enlarging
1382 of the max tasks handling capabilities of the scheduler.
1383 Affected files lib/silcutil/silcschedule.[ch].
1385 Wed Feb 20 20:41:01 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1387 * Added automatic extern "C" { ... } for C++ compilers so the
1388 application does not need to define them. Affected file
1389 includes/silcincludes.h.
1391 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
1392 old name went against naming convention. Applications now
1393 include "silcclient.h" instead of "clientlibincludes.h".
1394 Removed includes/clientlibincludes.h, it is redundant now.
1396 * Renamed includes/version.h to silcversion.h.
1398 * Added really preliminary support for OS/2 into the util
1399 library. Only thread & mutex API is implemented, others
1400 are still to be implemented. Created the lib/silcutil/os2/
1401 directory. Created also file includes/silcos2.h.
1403 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1405 * Added preliminary BeOS support into the util library.
1406 Created lib/silcutil/beos/, and implemented all the needed
1407 functions to support SILC on BeOS. Created also file
1408 includes/silcbeos.h.
1410 Mon Feb 18 15:49:22 EET 2002 Timo Sirainen <tss@iki.fi>
1412 * Added proper initializations to silc's irssi code, so it's
1413 now possible to load it as module. Affected files
1414 irssi/src/silc/core/silc-core.c,
1415 fe-common/silc/fe-common-silc-core.[ch] and fe-text/silc.c
1417 Sun Feb 17 19:02:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1419 * Merged latest Irssi (0.8.1) from the irssi.org's CVS into
1422 * Fixed the silcdoc document generator to correct generate
1423 docs from all kinds of filenames. Affected files are
1424 util/robodoc/Source/generator.c, scripts/silcdoc/silcdoc
1426 * ROBOdoc documented lib/silcutil/silcmemory.h.
1427 Added also new function silc_memdup.
1429 * Removed lib/silcutil/silcbufutil.h and moved those routines
1430 to the lib/silcutil/silcbuffer.h.
1432 Sun Feb 17 15:52:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1434 * Added `user_count' to the SilcChannelEntry which now tells the
1435 number of users on the channel. The user count is now saved
1436 in normal server of global channels as well. Affected files
1437 silcd/server.c, idlist.h, packet_receive.c and command.c.
1439 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
1440 include file utility functions.
1442 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
1443 instead of calling directly OS routines.
1445 * Fixed NICK change printing in Irssi SILC Client. Fixed
1446 KICKED notify printing in Irssi SILC Client. Affected file
1447 irssi/src/silc/core/client_ops.c.
1449 * Fixed a NICK change bug in client library, to not recreate the
1450 client_entry->channels hash table everytime nick is changed.
1451 Affected file lib/silcclient/client.c.
1453 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1455 * ROBOdoc documented the lib/silcske/silcske.h, and improved
1456 the SKE interface a bit.
1458 * Fixed padding problem in PKCS#1. The padding was not actually
1459 random since the random number generator was used incorrectly.
1460 This security bug affects only when encrypting with PKCS#1, and
1461 it is not currently used at all in SILC. SILC only use signing
1462 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
1464 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1466 * Rewrote the notify handling in Irssi SILC client to not call
1467 the events as signals. Fixes problems with Perl support.
1468 Affected files irssi/src/silc/core/client_ops.c, silc-channels.c.
1470 * Send the auto-nicking NICK command in client library with
1471 little timeout after connecting. The affected file is
1472 lib/silcclient/client.c.
1474 * Added following new config file settings:
1475 channel_rekey_secs, key_exchange_rekey, key_exchange_pfs,
1476 key_exchange_timeout, conn_auth_timeout, connections_max,
1479 Implemented all the new config settings handling in the server.
1481 Optimized the use of SKE Mutual flag usage. Use it only
1482 if connection authentication protocol is not based in public
1485 Renamed all SilcServerConfigSection* to SilcServerConfig*
1486 to have a bit shorter names.
1488 Affected files silcd/serverconfig.[ch], server.[ch], and
1491 Sat Feb 16 02:46:43 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1493 * Cleaned up the listening sockets code, preparing for the rehash
1494 support. Affected file is silcd/server.c.
1496 * Fixed some output messages. Affected files are silcd/silcd.c,
1499 Fri Feb 15 19:10:20 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1501 * Create lib/doc/silcrng_intro.html document as introduction
1502 to SILC RNG. ROBOdoc documented lib/silccrypt/silcrng.h.
1504 Fri Feb 15 13:23:03 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1506 * Fixes to the silcd config template. Affected file is
1507 doc/example_silcd.conf.in.
1509 * Removed type casts from silc_calloc(), conforming to the
1510 CodingStyle. Affected file is lib/silcutil/silcconfig.c.
1512 * Removed param_name member from client, server, and router
1513 section structs, now identifying the param directly.
1515 Added CONFIG_FREE_AUTH macro in config file parsing.
1517 Affected files are silcd/serverconfig.[ch].
1519 Fri Feb 15 12:24:08 EET 2002 Timo Sirainen <tss@iki.fi>
1521 * Fixed command line parameter handling. All SILC initialization
1522 is now done in silc_core_init() which also fixes autoconnecting
1525 Affected files irssi/src/silc/core/silc-core.c,
1526 irssi/src/fe-text/silc.c.
1528 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1530 * Added new configuration options and blocks:
1531 keepalive_secs, reconnect_count, reconnect_interval,
1532 reconnect_interval_max, reconnect_keep_trying and
1533 require_reverser_lookup. Added ConnectionParam block, and
1534 implemented the connection parameters when connecting as
1535 initiator and when accepting connections as responder.
1537 Added CONFIG_IS_DOUBLE macro in config file parsing, to check
1538 whether given configuration value has been given already.
1540 Affected files silcd/serverconfig.[c], server.[c].
1542 * Splitted the doc/example_silcd.conf.in. Separated the crypto
1543 algorithm parts and created new file silcalgs.conf, that
1544 is now included from the example_silcd.conf.in.
1546 * Optimized the silc_server_connect_to_router_second to take
1547 the connection configuration object from the SilcServerConnection
1548 object instead of finding it during the connecting phase.
1549 Added the configuration object to SilcServerConnection struct.
1550 Affected files silcd/server_internal.h, server.c.
1552 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1554 * Add the client on channel after it was resolved at the
1555 channel message receiving, and it was not already on the
1556 channel. Affected file lib/silcclient/client_channel.c.
1558 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1566 * Unified the serverconfig.[ch]'s helper function interface.
1567 Affected file silcd/serverconfig.[ch].
1569 * Removed doc/example_silc.conf.in since it is redundant.
1570 The make install will now install irssi/silc.conf file.
1572 * Added new Passphrase and Publickey authentication methods to
1573 config file, allowing both public key and passphrase based
1574 authentication to be set at the same time.
1576 Added `prefer_passphrase_auth' setting in config file which
1577 can be used to set to prefer passwd auth if both passwd and
1578 public key is set. If not set, public key is preferred.
1579 This has effect only when being initiator (responder will try
1582 Added support for authentication with passphrase and public key
1583 at the same time. The passphrase is tried first always since
1584 it is faster to check.
1586 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
1588 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1590 * Merged the new SILC Config library, with the server parsing
1591 support. Read the header file silcconfig.h or the toolkit
1592 documentation for the news. Affected files are

1614 * Allow zero length channel messages inside the Channel Message
1615 Payload. Affected file lib/silccore/silcchannel.c.
1617 * Fixed scripts/silcdoc/silcdoc to support all kinds of filenames
1618 as header filenames.
1620 * Removed lib/silcclient/README and created HTML file
1621 lib/silcclient/silcclient_using.html, which is now included
1622 as part of Toolkit documentation.
1624 Thu Feb 7 10:12:25 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1626 * Fixed CUMODE_CHANGE notify handling to change the mode of
1627 correct client. Affected file lib/silcclient/client_notify.c.
1629 * Make silc_rng_alloc fail if it cannot allocate the sha1
1630 hash algorithm. Affected file lib/silccrypt/silcrng.c.
1632 Sun Feb 3 17:20:52 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1634 * Fixed the file transfer's key agreement payload to include
1635 zero port also if the hostname is NULL because it could not
1638 Call file transfer monitor callback now also if error occurs
1639 during key agreement protocol.
1641 Changed the silc_client_file_send interface to return the
1642 SilcClientFileError instead of session id. The session ID
1643 is returned into pointer provided as argument.
1645 Check that the file exists locally before sending the
1646 file transfer request at all.
1648 Affected file lib/silcclient/client_ftp.c, silcapi.h.
1650 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer
1651 error than can occur while key agreement protocol. Affected
1652 file lib/silcclient/silcapi.h.
1654 * Fixed the event_mode CMODE handler to not crash when mode
1655 is changed and +k mode is set in the channel. Affected file

1658 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
1659 SILC_LOG_WARNING to give out Warning and not Error. Affected
1660 file lib/silcutil/silclog.c.
1662 * Fixed the channel message payload decryption in the function
1663 silc_channel_message_payload_decrypt to not modify the original
1664 buffer before it is verified that the message decrypted
1665 correctly. Otherwise, next time it is called with correct
1666 channel key it won't encrypt since the payload is corrupted.
1667 Affected file lib/silccore/silcchannel.c.
1669 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1671 * Do not constantly resize the window. A fix patch by cras.

1679 Fri Feb 1 22:33:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1681 * Fixed a bug in hash table internal routine for traversing
1682 the table with foreach callback. The current entry may
1683 become invalid in the callback but it was referenced after
1684 the callback returned.
1686 Do not allow auto rehashing of hash table during the
1687 silc_hash_table_foreach operation, for same reasons as it is
1688 not allowed for SilcHashTableList. Affected files are
1689 lib/silcutil/silchashtable.[ch].
1691 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1693 * Defined DLLAPI into silcincludes.h and silcwin32.h for
1694 Win32 DLL. extern's in header files are now declared with
1697 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1699 * Fixed private message handling. It used some old code that
1700 caused the client to crash. Affecte file is
1701 lib/silcclient/client_prvmsg.c.
1703 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1705 * Added function silc_client_add_channel,
1706 silc_client_replace_channel_id, and removed functions
1707 silc_client_new_channel_id and silc_idlist_get_channel_by_id
1708 from client library.
1710 * Added cross reference of the joined channels to the
1711 SilcClientEntry, and changed the SilcChannelEntry's
1712 users list to SilcHashTable. The affected files are
1713 lib/silcclient/idlist.[ch].
1715 * Fixed a bug in hash table tarversing. While the hash table
1716 is traversed with SilcHashTableList the table must not be
1717 rehashed. It is now guaranteed that auto rehashable tables
1718 are not rehashed while tarversing the list. Also defined that
1719 silc_hash_table_rehash must not be called while tarversing
1720 the table. Added function silc_hash_table_list_reset that must
1721 be called after the tarversing is over. The affected files are
1722 lib/silcutil/silchashtable.[ch].
1724 * Changed all hash table traversing to call the new
1725 silc_hash_table_list_reset in server and in client library.
1727 * Added function silc_client_on_channel to return the
1728 SilcChannelUser entry if the specified client entry is joined
1729 on the specified channel. This is exported to application as
1730 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
1732 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1734 * Fixed founder regaining problem with JOIN command on normal
1735 server. The notify for mode change must be sent always and
1736 not only if !cmd->pending. Affected file silcd/command.c.
1738 * Fixed the WHOWAS command's reply sending to support the
1739 lists correctly. Affected file silcd/command.c.
1741 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1743 * When sending JOIN command to router for processing the
1744 sender's old command identifier was not saved back to the
1745 sender's command context, fixed now. The affected file is
1748 * Create the key in JOIN command of the router did not return
1749 the channel key, added check for this. Affected file is
1752 * Fixed a channel ID update bug in JOIN command reply. Do
1753 not directly upgrade the ID but call the function
1754 silc_idlist_replace_channel_id if the ID was changed.
1755 Affected file silcd/command_reply.c.
1757 * Fixed memory leaks from command calling if it would fail.
1758 Affected file silcd/command.c.
1760 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1762 * Applied patches from cras:
1764 Memory leak fixes around libaries, irssi window resize fix,
1765 new silclist.h and silcdlist.h, all extern inline changed to
1768 * Removed dotconf from lib/dotconf, not needed anymore.
1770 * Removed TRQ from lib/trq, not needed anymore.
1772 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
1773 with server connections. Later this will be configurable
1774 in config file after new config file is done. Affected file
1777 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1779 * Fixed a crash in server related to channel announcements.
1780 Affected file silcd/server.c.
1782 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1784 * Fixed memory leaks in silc_server_create_new_channel*
1785 functions. Affected file silcd/server.c.
1787 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
1788 which ID was changed. This way the router will send the
1789 user list for the channel again, and server won't be in
1790 desync in some rare circumstances. Affected file is
1791 silcd/packet_receive.c.
1793 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1795 * Check for NULL socket pointer in the function
1796 silc_server_packet_send_to_channel_real. Affected file

1804 * Fixed some header addition to Toolkit distribution in
1805 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
1807 * Added lib/silcclient/client_ops_example.h as an template
1808 file for application programmers to quickly start using
1809 the SilcClientOperation functions in their application.
1810 Updated the lib/silcclient/README as well to tell about this
1811 nice file made available.
1813 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1815 * Call silc_server_remove_from_channels when removing client
1816 entry when NO_SUCH_CLIENT_ID was received. Affected file
1817 is silcd/command_reply.c.
1819 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1821 * Added server & router operator statistics updating. Affected
1822 file silcd/packet_receive.c and silcd/command.c.
1824 * Fixed the SERVER_SIGNOFF notify handling on normal server
1825 not to save the history information for clients. Same was
1826 fixed earlier in remove_clients_by_server function, but not
1827 here. Affected file silcd/packet_receive.c.
1829 * Raised the default connection-retry count from 4 to 7 in
1830 server. Affected file silcd/server.h.
1832 * Cancel any possible reconnect timeouts when we start the
1833 key exchange. Affected file silcd/server.c.
1835 * Do not reconnect on connection failure when SCONNECT was
1836 given. Affected files silcd/server.[ch].
1838 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1840 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
1842 * Fixed the NICK command to always give the unformatted
1843 nickname to the one giving the NICK command. If unformatted
1844 nickname is cached already it will be formatted and the
1845 local entry will always get the unformatted nickname.
1846 Affected file lib/silcclient/idlist.c.
1848 * Fixed some double frees from client library commands.
1849 Affected file is lib/silcclient/command.c.
1851 * Fixed CUMODE command in server to assure that no one can
1852 change founder's mode than the founder itself, there was a
1853 little bug. Affected file silcd/command.c.
1855 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1857 * Removed the SilcClientCommandDestructor from the client
1858 libary, it is not needed anymore. Affected files are
1859 lib/silcclient/silcapi.h, command[_reply].[ch],
1860 client_notify, idlist.c.
1862 * Fixed GETKEY command to first resolve client, and then
1863 resolve the server only if the client was not found, instead
1864 of resolving both at the same time. Affected file is
1865 lib/silcclient/command.c.
1867 * Added silc_client_start_key_exchange_cb and lookup the
1868 remote hostname and IP address before starting the key
1869 exchange with server. The affected file is
1870 lib/silcclient/client.c.
1872 * The server's public key is now saved using the IP address
1873 of the server and not the servername for the filename.
1874 The hostname public key filename is checked as an fall back
1875 method if the IP address based filename is not found.
1877 Fixed the GETKEY command to save the fetched server key
1878 in correct filename.
1880 Print the remote server's hostname now when new key is
1881 received during connection process. Affected file is
1882 irssi/src/silc/core/client_ops.c.
1884 * Return always our own public key to the client if it asks
1885 for it with GETKEY command. Affected file silcd/command.c.
1887 * Removed the use_auto_addr variable from default config
1888 file since it was in wrong section. Affected file is
1891 * Fixed TOPIC_CHANGE notification to not route it when it
1892 was sent using silc_server_send_notify_to_channel function.
1893 Affected file silcd/command.c.
1895 * Fixed silc_server_send_notify_kicked to send the kicker's
1896 Client ID also, it was missing. Affected files are
1897 silcd/command.c, silcd/packet_send.[ch].
1899 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1901 * Do not save client history information in SERVER_SIGNOFF.
1902 Fixes the bug in normal server that it does not detect
1903 the client becoming valid after the server becomes back
1904 online. Affected file silcd/server_util.c.
1906 * Added `sock_error' field into the SilcSocketConnection
1907 context. When error occurs during socket operation (read
1908 or write) the error is saved. Added also new function
1909 silc_socket_get_error to return human readable socket error
1910 message. Affected files are lib/silcutil/silcsockconn.[ch],
1911 lib/silcutil/unix/silcunixsockconn.c, and
1912 lib/silcutil/win32/silcwin32sockconn.c.
1914 * The server now prints the socket error message in the
1915 signoff for client. Affected file silcd/server.c.
1917 * Fixed the `created' channel information sending from router
1918 to server in JOIN command. Checks now whether the channel
1919 really was created or not and set it according that.
1921 Fixed the JOIN command to use the client entry's current
1922 ID during the joining procedure instead of the one it sent
1923 in the command (it is checked though), since it can change
1924 between the packet processing and command processing, and
1925 would just case unnecessary pain in the client end. Affected
1926 file silcd/command.c.
1928 * Fixed a channel key payload sending to use correct channel
1929 ID when the server was forced to change the channel's ID by
1930 router. Router sent the key payload with the old Channel ID.
1931 Affected file silcd/packet_receive.c.
1933 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1935 * Call silc_server_save_channel_key only if the key payload
1936 was provided in the JOIN command's command reply. Affected
1937 file silcd/command_reply.c.
1939 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1941 * Fixed silc_mp_sizeinbase to return the value correctly with
1942 MPI. Affected file lib/silcmath/mp_mpi.c.
1944 * Fixed the stop_server signal to correctly stop the scheduler
1945 and gracefully stop the server when SIGTERM or SIGINT signals
1946 are received. Affected file silcd/silcd.c.
1948 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1950 * Simple handling of TERM and HUP signals. Also added some log
1951 flushing call around. Affected file is
1954 * Fixed small bugs in silclog.c. Now buffering output will take
1955 effect after 10 seconds since startup: This will ensure that
1956 no important startup messages are lost. Also output redirection
1957 will preserve original format ([Date] [Type] message).
1958 Affected file is lib/silcutil/silclog.c.
1960 * Added two options to the config file, in the logging section:
1961 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1962 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1964 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1966 * Do not print the warning about log files not being initialized
1967 more than once to avoid excess logging. Affected file is
1968 lib/silcutil/silclog.c.
1970 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1971 the SIM copying in make install in Makefile.am.pre.
1973 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1975 * Rewritten silclog APIs. Globally interesting changes follows:
1976 silc_log_set_files() changed to silc_log_set_file().
1977 silc_log_set_callbacks() changed to silc_log_set_callback().
1978 ROBOdoc documented silclog header file.
1979 SilcLogCb now returns bool to wether inihibit the default
1980 handler or not (to keep the old behaviour return always TRUE).
1981 The new APIs should also fix the problem of the
1982 silcd_error.log file that was written in the current directory.
1985 Log files streams will remain opened after silc_log_set_file()
1986 call, means less CPU usage notably on high traffic servers.
1987 File streams are now full buffered, and flushed to the disk
1988 every 5 minutes, lesses HD activity and CPU usage.
1989 Messages can be redirected, allowing admins to configure
1990 one single logfile for all server messages.
1991 the silc_log_quick global variable to activate fast-logging.
1992 Affected files lib/silcutil/silclog.[ch]
1994 * Changed some code to conform new silclog APIs. Affected
1995 files are doc/example_silcd.conf.in, silcd/server.c
1996 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1999 * Fixed a memory leak that could occur in some situations.
2000 Affected file silcd/serverconfig.c.
2002 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2004 * Added the silc_client_del_client to remove the client from
2005 all channels as well. Affected file lib/silcclient/idlist.c.
2007 * Fixed the client library to correctly remove the client
2008 from all channels when the client entry is being destroyed.
2009 Affected file lib/silcclient/client_notify.c, command.c.
2011 * Added auto-nicking support to the client library. If the
2012 applicatio now sets client->nickname it will be sent to the
2013 server after connecting by the library. This way for example
2014 SILCNICK (or IRCNICK) environment variables will have effect
2015 and always change the nickname automatically to whatever
2016 it is wanted. Affected file lib/silcclient/client.[ch].
2018 * Renamed silc_server_command_bad_chars to the
2019 silc_server_name_bad_chars and moved it to the
2020 silcd/server_util.[ch]. Added also new function
2021 silc_server_name_modify_bad to return nickname that
2022 includes bad characters as new nickname without those
2023 bad characters. This check and modify is now used in
2024 silc_server_new_client when the username is initially set
2025 as nickname, so it must be checked to be valid nickname.
2026 Affected file silcd/packet_receive.c.
2028 * The nickname length is now taken from the packet for real
2029 and not trusted to strlen() since it clearly can return
2030 wrong length for nickname including bad characters. This
2031 also applies to channel names. Affected file silcd/command.c.
2033 * Removed the lib/silcsilm/modules directory. Modules are now
2034 compiled into the lib/silcsim. Fixed the copying of the
2035 modules to follow symbolic links in Makefile.am.pre.
2037 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2039 * Fixed silc_string_regexify list creation. Fixes bugs with
2040 BAN and INVITE commands in server. The affected file is
2041 lib/silcutil/unix/silcunixutil.c.
2043 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2045 * Removed the command destructor entirely from the server's
2046 command and command reply routines. It is not needed, and
2047 its usage was buggy and caused crashes. Affected files are
2048 silcd/command[_reply].[ch].
2050 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2052 * Cancel protocol and NULL sock->protocol if timeout
2053 occurred during protocol. Affected file silcd/server.c.
2055 * Cancel protocol timeouts always before calling the final
2056 callback, to assure that after final callback is called
2057 no other state will be called for the protocol anymore.
2058 Affected file silcd/protocol.c.
2060 * Print error log if incoming connection configuration could
2061 not be found. Affected file silcd/server.c.
2063 * Fixed JOIN command to correctly save the founder mode
2064 to the client on normal SILC server, when the channel
2065 was created by the router. Affected file silcd/command.c.
2067 * Fixed LIST command (hopefully) to send correct reply
2068 packets. Affected file silcd/command.c.
2070 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2072 * The silc_packet_receive_process now returns FALSE if the
2073 read data was invalid packet, and TRUE if it was ok.
2075 The server now checks that if unauthenticated connection
2076 sends data and its processing fails the server will close
2077 the connection since it could be a malicious flooder.
2079 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
2081 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2083 * Make sure the warning about error opening a log file is
2084 printed only once and not everytime it fails (produces
2085 too much useless log). Affected file lib/silcutil/silclog.c.
2087 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2089 * Made the silc_server_daemonise() function more readable.
2090 Affected file silcd/server.c.
2092 * Pid file is now optional, the user may comment it out from
2093 the config file. Removed define SILC_SERVER_PID_FILE, we
2094 don't need a default any longer. Affected file
2095 configure.in.pre, lib/Makefile.am.pre.
2097 * Make some use of the pid file. The server now dies at startup
2098 if it detects a valid pid file on his path. The server would
2099 die anyway in this circumstance, because of the bind() failure.
2100 Affected file silcd/silcd.c.
2102 * No longer compiling lib/dotconf.
2104 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2106 * Fixed JOIN command parsing not to crash. Affected file
2107 lib/silcclient/command.c.
2109 * Fied the NICK_CHANGE notify to add the new client entry
2110 even it is resolved. This removes an <[unknown]> nick
2111 thingy bug in the client. Affected file is
2112 lib/silcclient/client_notify.c.
2114 * Do not try to allocate 0 bytes (efence does not like it)
2115 in lib/silccore/silccomand.c when encoding payload.
2117 * Do not take IRCNICK as nickname in Irssi SILC client since
2118 it is not possible to set nickname before hand connecting
2119 the server (TODO has an entry about adding auto-nicking
2122 * Changed the silc_server_command_pending to check whether
2123 there already exists an pending entry with the specified
2124 command, command identifier and pending callback. This is
2125 to fix IDENTIFY and WHOIS related crashes that may register
2126 multiple pending commands with same identifier. Affected
2127 file silcd/command.c.
2129 * Fixed the server to reconnect to the router even if it
2130 was already reconnecting and EOF was received. This to
2131 fix a possibility that the server wouldn't ever try to
2132 auto-reconnect to the router. Affected file silcd/server.c.
2134 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2136 * Fixed the server's password authentication to use the
2137 length of the locally saved password, and not the one
2138 sent in the packet. Affected file silcd/protocol.c.
2140 * Fixed same password authentication problem in the
2141 Authentication Payload handling routines in
2142 lib/silccore/silcauth.c.
2144 * Yet another password authentication problem fixed with
2145 channel password handling in silcd/command.c.
2147 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2149 * If first character of string in silc_parse_userfqdn is '@'
2150 then do not parse it. Affected file is
2151 lib/silcutil/silcutil.c.
2153 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2155 * Fixed minor bug in IDENTIFY command reply sending, which
2156 caused various weird problems during JOIN when it was
2157 resolving names for users. Affected file silcd/command.c.
2159 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2161 * Fixed the IDENTIFY command reply sending to chech better valid
2162 clients. It was possible to send incomplete list of replies.
2163 Affected file silcd/command.c.
2165 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2167 * Added silc_client_command[s]_[un]register functions now to
2168 dynamically register the commands in client library. Removed
2169 the static table of commands. This allows the client library
2170 to call commands without causing the application to know about
2171 what commands library has called.
2173 Removed the INFO command reply kludge to detect when the command
2174 was called by library. Now library use its own command reply
2175 function for INFO command.
2177 Added function silc_client_command_call to call a command.
2178 Application can use it to call command, not access the structure
2181 Now all commands that are sent by the client library (not
2182 explicitly sent by application) use own command reply functions.
2184 Affected files around lib/silcclient/ and in
2185 irssi/src/silc/core/.
2187 * Fixed the WHOIS command reply sending to chech better valid
2188 clients. It was possible to send incomplete list of replies.
2190 Fixed the WHOIS and IDENTIFY to send the request to router
2191 if normal server did not do it and did not find any results.
2193 Affected file silcd/command.c.
2195 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2197 * Moved the internal data from SilcClient context into its
2198 own file, not accesible to application. Affected files
2199 lib/silcclient/client.h and lib/silcclient/client_internal.h,
2200 and other files in client library.
2202 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2204 * Added doc/examples installation target in Makefile.am.pre.
2207 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2209 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
2210 commands the found client entry will be removed from the
2211 cache, after notifying application about the error. Affected
2212 file lib/silcclient/command_reply.c.
2214 * Changed the /MSG to check for exact nickname user gave, and
2215 not let `nick' match `nick@host' if it is only one found. Now,
2216 user must type the exact nickname (like nick@host2) even if
2217 there are no more than one same nicks found. This is to avoid
2218 a possibility of sending nickname to wrong nickname since
2219 `nick' could match `nick@host'. Affected file is
2220 irssi/src/core/silc-servers.c.
2222 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2224 * Do not print "you are now server operator" or similar when
2225 giving /away command. Affected files are
2226 irssi/src/silc/core/client_ops.c, silc-servers.h.
2228 * Made the silc_server_command_pending_error_check to send
2229 the same command reply payload it received back to the
2230 original sender of the command. This way all arguments
2231 that was received by the server will be received by the
2232 client too. Affected file silcd/command.c.
2234 * Added the silc_idcache_add to return the created cache entry
2235 to a pointer. Affected file lib/silccore/silcidcache.[ch].
2237 * Add global clients to expire if they are not on any channel.
2238 This is because normal server will never know if they signoff
2239 if they are not on any channel. The cache expiry will take
2240 case of these entries. This is done by normal servers only.
2241 The affected files are silcd/command_reply.c,
2242 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
2244 * If server receives invalid ID notification for WHOIS or
2245 IDENTIFY and the ID exists in the lists, it is removed.
2246 Affected file silcd/command_reply.c.
2248 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
2249 in client then client entry that it matches is searched and
2250 the nickname is printed on the screen for user. Affected
2251 file irssi/src/silc/core/client_ops.c.
2253 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2255 * Use cache entry expire time in the LIST command reply to
2256 purge old entries from the cache after the LIST command
2257 reply has been received. This way we don't have non-existent
2258 entries in the cache for too long. Affected file is
2259 silcd/command_reply.c.
2261 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2263 * If we are normal server, and we've not resolved client info
2264 in WHOIS or IDENTIFY from router, and it is global client,
2265 we'll check whether it is on some channel. If it is not
2266 then we cannot be sure about its validity and will resolve it
2267 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
2268 file silcd/command.c.
2270 * Search channel by name (if possible) rather than by ID
2271 in IDENTIFY command's command reply. Affected file is
2272 silcd/command_reply.c.
2274 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2276 * Distribute to the channel passphrase in CMODE_CHANGE notify.
2277 Updated specs and implemented it. Affected file silcd/command.c,
2278 silcd/packet_send.c and silcd/packet_receive.c.
2280 * Implemented the <founder auth> payload handling in the JOIN
2281 command. If provided all conditions for channel joining
2282 except requirement to provide correct passphrase can be
2283 overrided by the channel founder. Updated the protocol specs.
2284 Affected file silcd/command.c.
2286 Added support for founder auth in JOIN command in client
2287 library. Fixed the parsing of the JOIN command now to support
2288 all options as they should be. The affected file is
2289 lib/silcclient/command.c.
2291 * Optimized the WHOIS and IDENTIFY commands to send the request
2292 to router only if it includes nicknames or other names. If
2293 they include only IDs then check the local cache first before
2294 routing. Affected file is silcd/command.c.
2296 * Added channels topic announcements. Affected file is
2297 silcd/packet_receive.c and silcd/server.c.
2299 * Fixed the silc_server_send_notify_topic_set to really destine
2300 the packet to channel. Affected file silcd/packet_send.c.
2302 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
2303 library. Affected file lib/silcclient/client_notify.c.
2305 * Added UMODE announcements. Affected file silcd/server.c.
2307 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2309 * Memory leak fixes in:
2311 lib/silcutil/silcsockconn.c
2312 lib/silcske/silcske.c
2313 lib/silcske/groups.c
2315 lib/silccrypt/silcpkcs.c
2316 lib/silccore/silccommand.c
2317 lib/silccore/silcidcache.c
2322 * ROBOdoc documented the lib/silcske/groups.h file and a
2323 bit changed the interface for better.
2325 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2327 * Update the client entry context in the ID cache after
2328 nick change. Affected file lib/silcclient/command.c.
2329 Fixes the CUMODE command when regaining founder privileges,
2330 and a little WHOIS problem.
2332 * Fixed silc_net_gethostbyname to correctly call the
2333 inet_ntop. Affected file lib/silcutil/silcnet.c.
2335 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2337 * Added IPv6 support checking to the configure.in.pre, added
2338 also --enable-ipv6 option to override the check. Affected
2339 file configure.in.pre.
2341 * The silc_thread_create now calls the start function
2342 directly if threads support is not compiled in. Removes
2343 ugly #ifdef's from generic code. Affected files are
2344 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
2346 * Added silc_net_gethostby[name/addr]_async to asynchronously
2347 resolve. Affected files are lib/silcutil/silcnet.[ch].
2349 * Added support for rendering IPv6 based server, client and
2350 channel IDs. Affected file lib/silcutil/silcutil.c.
2352 * Added support for creating IPv6 based server IDs. Affected
2353 file is silcd/serverid.c.
2355 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2357 * Added silc_net_gethostby[addr/name] into the
2358 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
2359 routines. Added silc_net_is_ip[4/6]. Affected file is
2360 lib/silcutil/unix/silcunixnet.c. All routines that take
2361 address as argument now supports both IPv4 and IPv6 addresses.
2363 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2365 * Fixed LIST command reply sending in server. Affected file
2368 * Server now sends the kicker's client ID in the KICK notify
2369 to the kicked client. Affected file silcd/command.c.
2371 * The client library now parses the kickers client ID and
2372 UI displays it. Affected files lib/silcclient/client_notify.c
2373 and irssi/src/silc/core/silc-channels.c, module-formats.c.
2375 * Made all payload parsing function prototypes consistent.
2376 They all take now const unsigned char * and uint32 pair as
2377 the payload data instead of SilcBuffer. Changes all around
2378 the source tree. Other unsigned char* -> const unsigned char*
2379 changes around the tree as well.
2381 * Optimized SFTP client and server packet sending not to
2382 allocate new buffer for each packet but to recycle the
2383 first allocated buffer. Affected files are
2384 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
2386 * Optimized the SFTP client to use SilcList instead of
2387 SilcDList for requests, because it is faster. Affected file
2388 is lib/silcsftp/sftp_client.c.
2390 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
2391 into lib/silccore/silcid.[ch].
2393 Renamed silcpayload.[ch] into silcargument.[ch].
2395 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2397 * If client entry is deleted with active key agreement
2398 session, abort the session.
2400 The silc_client_abort_key_agreement now calls the completion
2401 callback with new SILC_KEY_AGREEMENT_ABORTED status.
2403 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
2406 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2408 * Don't use __restrict in older GCC's. Affected file is
2409 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
2411 * silc_net_localhost now attempts to reverse lookup the
2412 IP/hostname. Affected file lib/silcutil/silcnet.c.
2414 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
2415 command. It can be used to gain founder privileges at
2416 the same time when joining the channel.
2418 Defined that the SILC_NOTIFY_TYPE_KICKED send the
2419 kicker's client ID as well. Updated protocol specs.
2421 Defined that the server must send SILC_COMMAND_IDENTIFY
2422 command reply with error status to client who sent
2423 private message with invalid client ID.
2425 Updated the protocol specification.
2427 * Added silc_server_send_command_reply to send any
2428 command reply. Affected file silcd/packet_send.[ch].
2430 * Added silc_id_payload_encode_data to encode ID payload
2431 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
2433 * The server now send IDENTIFY command reply with error
2434 status if client ID in private message is invalid. Affected
2435 file silcd/packet_receive.c.
2437 * Save the server key file with server's IP address in
2438 the filename instead of hostname. The affected file is
2439 irssi/src/silc/core/client_ops.c.
2441 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2443 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
2446 * Added libtool support for compiling shared objects in
2447 lib/silcsim. Affected file configure.in.pre and
2448 lib/silcsim/Makefile.am. Original patch by cras.
2450 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2452 * Pid file configuration, and server's config file fixes
2453 patch by toma. Updated CREDITS file.
2455 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2457 * Fixed silc_client_channel_message to not try to decrypt
2458 the message twice if it resolved the destination client
2459 information. This could cause of dropping one channel
2460 message. Affected file lib/silcclient/client_channel.c.
2462 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2464 * Added silc_client_run_one into lib/silcclient/silcapi.h and
2465 lib/silcclient/client.c. This function is used when the SILC
2466 Client is run under some other scheduler, or event loop or
2467 main loop. On GUI applications, for example this may be
2468 desired to used to run the client under the GUI application's
2469 main loop. Typically the GUI application would register an
2470 idle task that calls this function multiple times in a second
2471 to quickly process the SILC specific data.
2473 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2475 * Fixed silc_server_drop() for dropping the supplementary
2476 groups as well, this could cause a security hole on some
2479 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2481 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by

2485 to run server on foreground. A patch by debolaz.
2486 Affected files silcd/server.c, silcd/silcd.c.
2488 * Fixed MOTD to return the MOTD file server name. Affected
2489 file silcd/command.c.
2491 * Added INFO command reply handling to the Irssi SILC Client.
2492 Affected file irssi/src/silc/core/client_ops.c.
2494 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2496 * Fixed the silc_idcache_list_* routines to really support
2497 the dynamic list. Fixes a crash. Affected file is
2498 lib/silccore/silcidcache.c.
2500 * Fixed the LIST command reply to really call LIST command's
2501 pending callbacks. Affected file silcd/command_reply.c.
2503 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2505 * Update conn->local_entry->nickname after giving NICK
2506 command. Affected file lib/silcclient/command.c.

2510 * Added the [pid] option to the silcd configuration file
2512 Affected files: serverconfig.[ch] and silcd.c
2514 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2516 * Save fingerprint in WHOIS command reply in server.
2517 Affected file silcd/command_reply.c.
2519 * Fixed NICK commands pending callback registration.
2520 Affected file lib/silcclient/command.c.
2522 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2524 * Use ++server->cmd_ident when sending commands in server,
2525 instead of random number. Affected file silcd/command.c.
2527 * Fixed GETKEY command reply to call actually GETKEY pending
2528 command callbacks. Affected file silcd/command_reply.c.
2530 * A bit stricter check for nicknames. Check for same nickname
2531 in NICK command also. Affected file silcd/command.c.
2533 * Do not call INFO command everytime client ID changes, only
2534 during first connecting. Affected file lib/silcclient/client.c.
2536 * Set the new nickname only after successful command reply for
2537 NICK command is returned by server. Affected file
2538 lib/silcclient/command.c.
2540 * Remove nicknames from nicklist during server_signoff notify.
2541 Should fix /NAMES bit more. The affected file is
2542 irssi/src/silc/core/silc-channels.c.
2544 * Added `fingerprint' field to the SilcIDListData in the
2545 silcd/idlist.h to hold the fingerprint of the client's
2548 Send the fingerprint of the client's public key in WHOIS
2551 Affected files silcd/command.c, and silcd/idlist.[ch].
2553 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
2554 create fingerprint from given data.
2556 * Show the fingerprint of the client's public key in WHOIS.
2557 Affected files irssi/src/module-formats.[ch] and
2558 irssi/src/silc/core/client_ops.c.
2560 * Format the multiple same nicknames also during JOIN and
2561 NICK_CHANGE notifys. Affected file is
2562 lib/silcclient/client_notify.c.
2564 * Do not print error on screen for invalid private message
2565 payload since it can come if someone is sending private
2566 messages with wrong key. Affected file
2567 lib/silccore/silcprivate.c.
2569 * Fixed multiple concurrent /PING crash. Affected file
2570 lib/silcclient/command.c.
2572 * Changed the wrong ID encoding. All IP addresses must be
2573 in MSB first order in encoded format. They were encoded
2574 wrong and was in LSB format. Affected files are
2575 silcd/serverid.c, lib/silcutil/silcutil.c.
2577 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
2579 * Call the `connect' client operation through the scheduler
2580 in case of error. Affected file lib/silcclient/client.c.
2582 * Call the `failure' client operation even if the error
2583 occurred locally during a protocol. Affected file is
2584 lib/silcclient/protocol.c.
2586 * Added support of sending LIST command to router from normal
2587 server. This way normal server can get list of all channels
2588 in the network too. Fixed the channel list sending in the
2589 server too. Affected files are silcd/command.c, and
2590 silcd/command_reply.[ch].
2592 * Added silc_server_update_channels_by_server and
2593 silc_server_remove_channels_by_server. They are used during
2594 disconnection of primary router and in backup router protocol.
2595 Affected file silcd/server_util.[ch], silcd/server.c and
2596 silcd/server_backup.c.
2598 * Fixed channel adding to global list in IDENTIFY command
2599 reply in server. Affected file silcd/command_reply.c.
2601 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2603 * If the incoming packet type is REKEY or REKEY_DONE process
2604 that packet always synchronously. Fixes yet another MAC
2605 failed error on slow (dialup) connections. Affected file
2606 lib/silcclient/client.c and silcd/server.c.
2608 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2610 * Call check_version SKE callback for initiator too. Affected
2611 file lib/silcske/silcske.c.
2613 * Implemented fix for security hole found in the SKE that was
2614 fixed in the specification few days back; the initiator's
2615 public key is now added to the HASH value computation.
2616 Added backwards support for the old way of doing it too, for
2617 old clients and old servers. Affected file is
2618 lib/silcske/silcske.c.
2620 * Enabled mutual authentication by default in SKE. If initiator
2621 is not providing mutual authentication the responder will
2622 force it. This will provide the proof of posession of the
2623 private key for responder. The affected files are
2624 lib/silcclient/protocol.c and silcd/protocol.c.
2626 * Do not cache anymore the server's public key during SKE.
2627 We do mutual authentication so the proof of posession of
2628 private key is done, and if the server is authenticated in
2629 conn auth protocol with public key we must have the public
2630 key already. Affected file silcd/protocol.c.
2632 * Added new global debug variable: silc_debug_hexdump. If
2633 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
2634 file lib/silcutil/silclog.[ch].
2636 * Fixed compilation warning due to char * -> const char *.
2637 Affected files lib/silcutil/silcnet.h, and
2638 lib/silccore/silcauth.[ch].
2640 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2642 * Fixed CMODE command when new channel key was created. If
2643 the creation failed the old key was removed. Next time giving
2644 same command would crash the server since the old key was
2645 freed already. Affected file silcd/command.c.
2647 * Fixed the silc_server_announce_get_channels to not crash
2648 on reconnect. Affected file silcd/server.c.
2650 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2652 * Added silc_log_set_debug_string function to set a regex
2653 string to match for debug output. Only the function names,
2654 or filenames matching the given debug string is actually
2655 printed. This way it is possible to filter out those debug
2656 strings that user is not interested in.
2658 Fixed a bug in silc_string_regexify.
2660 Affected files lib/silcutil/silclog.[ch], and
2661 lib/silcutil/unix/silcunixutil.c.
2663 * Changed the -d options in both server and Irssi SILC client
2664 to take the debug string as argument. Affected files
2665 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
2667 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2669 * Added silc_hash_babbleprint to create a Bubble Babble
2670 Encoded fingerprint. The encoding is developed by Antti
2671 Huima (draft-huima-babble-01.txt), and it creates human
2672 readable strings out of binary data. Affected file
2673 lib/silccrypt/silchash.[ch].
2675 * Print the babble print now in addition of fingerprint as well
2676 in Irssi SILC client. Affected files are
2677 irssi/src/fe-common/silc/module-formats.[ch],
2678 irssi/src/fe-common/silc/core/client_ops.c.
2680 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2682 * Fixed a security problem found in SKE. The initiator's
2683 public key too is now added to the HASH hash value creation
2684 which is signed by the responder to create the SIGN value.
2685 This will prevent anyone in the middle to lie to the responder
2686 about the initiator's public key. If this is done now, the
2687 man in the middle will get caught. Updated the protocol
2690 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2692 * Better installation directory handling. Configure module
2693 paths and other paths automatically to example_silc* files
2694 in doc/. A patch by toma.
2696 * Fixed compiler warning from MPI library, and from SILC RNG.
2699 * Added SILC_SERVER_PID_FILE to define the pid file for server.
2700 It can be configured with ./configure. A patch by toma.
2702 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2704 * Find correct make to use in prepare-clean. A patch by
2705 toma. Affected file prepare-clean.
2707 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
2709 * Added irssi variables use_auto_addr, auto_bind_ip,
2710 auto_bind_port and auto_public_ip.
2712 * Changed the interface for silc_client_send_key_agreement
2713 in lib/silcclient/silcapi.h
2717 irssi/src/silc/core/silc-core.c
2719 lib/silcclient/silcapi.h
2720 irssi/src/silc/core/silc-channels.c
2721 lib/silcclient/client_keyagr.c
2724 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2726 * Added silc_pkcs_public_key_compare to compare two
2727 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
2729 * Check that the client who set the founder mode on the
2730 channel is the same client that is giving the founder
2731 mode to itself. It is done by comparing the saved public
2732 key (it is saved even in the authentication is passphrase).
2733 Affected file silcd/command.c.
2735 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2737 * Do not process packet for disconnected socket connection.
2738 Affected file lib/silccore/silcpacket.c.
2740 * Process the DISCONNECT packet through scheduler in the
2741 client library. Affected file lib/silcclient/client.c.
2743 * Fixed the silc_client_packet_parse to not to increase
2744 the packet sequence number if the conn->sock and the
2745 current socket connection is not same. This can happen
2746 for example during key agreement when the conn includes
2747 multiple socket connections (listeners). Affected file
2748 lib/silcclient/client.c.
2750 * The sender of the file transfer request now provides also
2751 the pointer (listener) for the key exchange protocol. If
2752 the listener cannot be created then it sends empty key
2753 agreement and lets the receiver provide the listener.
2755 Added `local_ip' and `local_port' arguments to the
2756 silc_client_file_send. If they are provided they are used,
2757 if not then it will attempt to find local IP address, if
2758 not found or bind fails then the remote client will provide
2761 Affected files are lib/silcclient/client_ftp.c and
2762 lib/silcclient/silcapi.h.
2764 * Extended the FILE SEND command to support defining the
2765 local IP and port for key exchange listener. They are
2766 optional. Affected file irssi/src/silc/core/silc-servers.c.
2768 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2770 * Defined to WHOIS command reply the sending of fingerprint
2771 of the client's public key (if the proof of posession of the
2772 corresponding private key is verified by the server).
2773 Updated to the protocol specification.
2775 * Added support of receiving the client's public key's
2776 fingerprint in command reply in client library. Affected
2777 file is lib/silcclient/command_reply.c, and
2778 lib/silcclient/idlist.[ch].
2780 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2782 * Do not send over 128 chars long nickname to the server
2783 in NICK command. Affected file lib/silcclient/command.c.
2785 * Do not send over 256 chars long channel names to the server
2786 in JOIN command. Affected file lib/silcclient/command.c.
2788 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2790 * Assure that silc_server_close_connection cannot be called
2791 twice for same socket context. Affected file is
2794 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2796 * Send error message to application if opening file for
2797 writing during file transfer fails. Affected file is
2798 lib/silcclient/client_ftp.c.
2800 Remove all file transfer sessions for a client that we're
2801 removing from ID cache.
2803 Affected file is lib/silcclient/client_ftp.c.
2805 * Fixed silc_net_addr2bin to return correct address. Affected
2806 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2808 * Fixed file transfer session removing on signoff notify.
2809 Affected file irssi/src/silc/core/silc-servers.c.
2811 * Added the SilcClientFileError to be returned in the monitor
2812 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
2813 Affected file lib/silcclient/silcapi.h.
2815 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2817 * Fixed a crash in silc_client_ftp_free_sessions and
2818 silc_client_ftp_session_free_client. Affected file
2819 lib/silcclient/client_ftp.c.
2821 * Added `disabled' field in the SilcChannelEntry in the server
2822 to indicate if the server entry is disabled. Affected file
2823 silcd/idlist.h, silcd/command[_reply].c.
2825 * SILC server adds now /var/run/silcd.pid everytime it is
2826 started. Affected file silcd/silcd.c.
2828 * Added silc_server_packet_send_clients to send a packet to
2829 the provided table of client entries. Affected file
2830 silcd/packet_send.[ch].
2832 * Fixed a crash in client resolving in client_prvmsg.c in
2833 client library. Affected file lib/silcclient/client_prvmsg.c.
2835 * Do not actually remove the client directly from ID cache
2836 during SERVER_SIGNOFF, but invalidate it. This way we
2837 preserve the WHOWAS info for the client. Affected file
2838 silcd/server_util.c.
2840 * Fixed SERVER_SIGNOFF notify handling in the server. The
2841 server is now able to process incoming SERVER_SIGNOFF notify
2842 for a server that it doesn't even know about. It will remove
2843 the clients provided in the notify. Affected file
2844 silcd/packet_receive.c.
2846 * Check for partial packet in data queue after every packet that
2847 was found from the queue. Return and wait for more data if
2848 there is partial data in queue. Affected file is
2849 lib/silccore/silcpacket.c.
2851 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2853 * Added SilcClietFileError enum to indicate error in
2854 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
2855 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
2856 Affected files lib/silcclient/silcapi.h and
2857 lib/silcclient/client_ftp.c.
2859 * Check that newsize in silc_buffer_realloc is larger than
2860 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
2862 * Added better monitor of file transfers. It now monitors
2863 key agreement protocol during the file transfer too. Added
2864 error reporting too. Affected files
2865 irssi/src/silc/core/silc-servers.c,
2866 irssi/src/fe-common/silc/module-formats.[ch].
2868 * Wrote a help file for FILE command.
2870 * Added silc_rng_global_get_byte_fast to get not-so-secure
2871 random data as fast as possible. Random data is read from
2872 /dev/urandom if available and from the SILC RNG if not
2873 available. It is used in padding generation. Affected file
2874 lib/silccrypt/silcrng.[ch].
2876 * All packets in client library are now processed synchronously.
2877 Optimized packet processing a lot. Affected file
2878 lib/silcclient/client.c.
2880 * All server connection packets are processing synchronously
2881 now in server, to optimize packet processing. Affected file
2884 * Include files are installed now only in Toolkit distribution
2885 if make install is given. Affected files: all Makefile.am's.
2887 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2889 * Assure that silc_client_notify_by_server_resolve does not
2890 resolve the client information multiple times. If it cannot
2891 be found by the first it cannot be found at all. Affected
2892 file lib/silcclient/client_notify.c.
2894 * Fixed WHOWAS command reply calling. Affected file
2895 lib/silcclient/command_reply.c.
2897 * Removed all references to silc_idlist_get_client from the
2898 Irssi SILC client since that call is internal call used by
2899 the library. The Irssi SILC client will use now client
2900 retrieval functions found in silcapi.h.
2902 * Fixed a bug in resolving nickname info before sending
2903 private message. It used freed memory. Affected file
2904 irssi/src/silc/core/silc-servers.c.
2906 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2908 * Assure my_channels statistics cannot go negative in server.
2909 Affected files silcd/server.c, silcd/server_util.c.
2911 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2913 * Upgraded dotconf 1.0.2 to 1.0.6 in lib/dotconf.
2915 Tue Oct 23 13:51:19 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2917 * Win32 Toolkit changes. Affected files
2918 win32/silc.dsw, win32/libsilc/libsilc.def,
2919 win32/libsilcclient/libsilc.def,
2920 lib/silcutil/silcutil.c, and
2921 lib/sftp/sftp_fs_memory.c.
2923 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2925 * Added silc_net_localip to return local host's IP address.
2926 Affected file lib/silcutil/silcnet.[ch].
2928 * If key exchange or rekey protocol is active for a connection
2929 parse all packets syncronously since there might be packets
2930 in packet queue that we are not able to process without first
2931 processing packets before them. Affected file silcd/server,
2932 lib/silcclient/client.c.
2934 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2935 whether library should continue processing the packet.
2936 Affected file lib/silccore/silcpacket.h.
2938 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
2939 SilcSFTPMonitorData to SFTP server to monitor various
2940 SFTP client requests. Affected file lib/silcsftp/silcsftp.h,
2941 lib/silcsftp/sftp_server.c.
2943 * Added silc_file_size to return file size. Affected file
2944 lib/silcutil/silcutil.[ch].
2946 * Implemented the file transfer support for the client library.
2947 Added preliminary support for simple client to client one-file
2948 transmission. Affected file lib/silcclient/client_ftp.c,
2949 lib/silccilent/client.[ch].
2951 * Added new local command FILE to the Irssi SILC Client.
2952 It is used to perform the file transfer. It has subcommands
2953 SEND, RECEIVE, SHOW and CLOSE. Affected files
2954 irssi/src/silc/core/client_ops.c,
2955 irssi/src/silc/core/silc-server.[ch].
2957 Mon Oct 22 12:50:08 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2959 * Relay the SILC_PACKET_FTP in the server. Affected files
2960 silcd/server.c and silcd/packet_receive.c.
2962 Sun Oct 21 20:21:02 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2964 * Renamed silc_file_read and silc_file_write to functions
2965 silc_file_readfile and silc_file_writefile. Added function
2966 silc_file_open and silc_file_close. Affected files
2967 lib/silcutil/silcutil.[ch].
2969 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2971 * Resolve the client info when received private message or
2972 channel message for a client which nickname we don't know.
2973 Affected files lib/silcclient/client_prvmsg.c and
2974 lib/silcclient/client_channel.c.
2976 * Do not crash in /KEY if client is not connected. Affected
2977 file irssi/src/silc/core/silc-channels.c.
2979 * Added SilcClientStatus field to the SilcClientEntry in the
2980 lib/silcclient/idlist.h.
2982 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
2983 is incomplete and is being resolved, it won't be resolved
2986 Make sure also that USERS command reply does not resolve
2987 twice information. Affected file is
2988 lib/silcclient/command_reply.c.
2990 Make sure that silc_client_get_clients_by_list does not
2991 resolve twice same information.
2993 * Check for valid client->id in the silc_server_free_client_data.
2994 Affected file silcd/server.c.
2996 * Fixed /GETKEY nick@server not to crash if the server entry
2997 is not found. Affected file lib/silcclient/command.c.
2999 * Fixed the silc_server_check_cmode_rights to check the
3000 requested modes correctly. Affected file silcd/command.c.
3002 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3004 * Better checks for non-printable chars in nick added.
3005 Affected file silcd/command.c.
3007 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3009 * Call the silc_server_udpate_servers_by_server in the
3010 primary router that comes back online in the backup resuming
3011 protocol. Otherwise it routes packets wrong. Affected file
3012 silcd/server_util.[ch], silcd/server_backup.c.
3014 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3016 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
3017 lib/silcutil/silcbuffmt.[ch].
3019 * Redefined the SILC packet header to include the padding
3020 length. Affected file lib/silccore/silcpacket.[ch].
3022 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
3023 length for maximum padding up to 128 bytes). Affected
3024 file lib/silccore/silcpacket.h.
3026 * Removed all backwards support for old 0.5.x MAC thingies.
3027 The SILC packet header change makes it impossible to be
3028 backwards compatible.
3030 * Send the ENDING packet with timeout in the backup resuming
3031 protocol. This is to assure that all routers has connected
3032 to the primary router. Affected file silcd/server_backup.c.
3034 * Changed the RNG to take the first IV from random data. It
3035 used to take it from zero actually. Changed the RNG also
3036 to use /dev/urandom during session. /dev/random is used
3037 in initialization. Affected file lib/silccrypt/silcrng.[ch].
3039 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3041 * Changed the SILC packet header to have the first two bytes
3042 (the packet length) encrypted. Affected files aroung the
3043 code tree, lib/silccore/silcpacket.[ch]. Removed the
3044 SilcPacketCheckDecrypt callback. It is not needed anymore
3045 since the silc_packet_receive_process will determine now
3046 whether the packet is normal or special.
3048 * Implemented the unidirectional MAC keys. Affected files
3049 lib/silcske/silcske.c, silcd/protocol.c and
3050 lib/silcclient/protocol.c.
3052 * Implemented the packet sequence number to the MAC computation.
3053 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
3054 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
3055 lib/silcclient/protocol.c.
3057 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3059 * Allow backup router to announce servers. All servers
3060 announced by backup router are added to the global list
3061 automatically. Update hte server's socket to our primary
3062 router also when backup router announces a server.
3063 Affected file silcd/packet_receive.c.
3065 * Do not update the client->router in the function
3066 silc_server_udpate_clients_by_server if the client is on
3067 global list. We might fail to find any specific server
3068 for locally connected clients and local cell clients. They
3069 should still use the `from' and not `to' as client->router.
3070 This fixes backup router resuming protocol. Affected file
3071 silcd/server_util.c.
3073 * Decrease channel statistics count only if the channel
3074 deletion worked. Affected files are silcd/server.c and
3075 silcd/server_util.c.
3077 * Added silc_server_update_servers_by_server to update origin
3078 of all server entries. Used during backup router protocol.
3079 Affected files silcd/server_util.[ch], silcd/server.c. and
3080 silcd/backup_router.c.
3082 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
3083 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
3084 silc_hmac_get_hash and silc_hmac_get_name. Affected file
3085 lib/silccrypt/silchmac.c.
3087 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3089 * Assure that router cannot reroute the same channel message
3090 to the sender. Affected file silcd/packet_receive.c.
3092 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3094 * Made better checks that the channel message is not sent
3095 to the router it came from. Affected file is
3096 silcd/packet_send.c. Fixed memory leak too.
3098 * Announce informations for incoming router connection, but
3099 only after checking if it is replaced by backup router.
3100 Affected file silcd/packet_receive.c.
3102 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3104 * Fixed the backup resuming protocol to work in multiple
3105 router environment. Affected file silcd/server_backup.c.
3107 * Route packet only to one router in the function
3108 silc_server_packet_send_to_channel. Affected file is
3109 silcd/packet_send.c.
3111 * Fixed silc_server_send_notify_dest to set the broadcast
3112 flag. Fixed the silc_server_send_notify_topic to actually
3113 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
3114 Affected file silcd/packet_send.c.
3116 * Changed the SFTP Filesystem interface. Changed the
3117 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
3118 the filesystem operation function. The SilcSFTPFilesystem
3119 is now a context that is allocated by all filesystem allocation
3120 functions and it already includes the operations structure
3121 and filesystem specific context. It is given as argument
3122 now to the silc_sftp_server_start. This made the interface
3123 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
3124 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
3126 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3128 * Changed the backup router adding and getting interfaces
3129 in the server. The router that will be replaced by the
3130 specified backup router is now sent as argument. Affected
3131 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
3134 * Added silc_net_addr2bin_ne to return the binary form of
3135 the IP address in network byte order. Affected files
3136 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
3138 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3140 * Check for existing server ID in silc_server_new_server
3141 and in silc_server_connect_to_router_final and remove the
3142 old entry if it exists. Affected file silcd/packet_receive.c,
3145 * Send the channel message always to only one router, either
3146 in upstream or downstream. Affected file is
3147 silcd/packet_send.c.
3149 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3151 * Wrote the definition of the backup resuming protocol to the
3152 protocol specification.
3154 * Removed one redundant channel key generation from normal
3155 server during joining procedure. Removed one redundant
3156 channel key sending from server to router during joining
3157 procedure. Affected file silcd/command.c.
3159 * Made minor bugfixes to the backup router resuming protocol.
3160 Affected file silcd/server_backup.c, server.c.
3162 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3164 * Added --disable-asm configuration option. Affected files
3165 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
3168 * Implemented the backup resuming protocol that is used to
3169 resume the primary router position in the cell after the
3170 primary router comes back online. Affected files
3171 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
3172 and silcd/server_util.[ch].
3174 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3176 * Sleep two (2) seconds after sending QUIT command to server.
3177 Affected file lib/silcclient/command.c.
3179 * Assure that if outgoing data buffer is pending do not force
3180 send any data. Affected file silcd/packet_send.c.
3182 * Assure that if outgoing data buffer is pending do not force
3183 send any data. Affected file lib/silcclient/client.c.
3185 * Implemented the backup router support when the primary router
3186 goes down. The servers and routers can now use the backup
3187 router as new primary router without loosing connectivity.
3189 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3191 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
3192 in the server to indicate disabled entry. All data read
3193 from the connection will be ignored and no data is sent
3194 for entry that is disabled. Affected files are
3195 silcd/idlist.h, silcd/server.c.
3197 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3199 * Created SFTP client and server test programs in the
3200 lib/silcsftp/tests directory.
3202 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3204 * Implemented memory filesystem (virtual filesystem) for
3205 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
3208 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3210 * Implemented the SFTP (SSH File Transfer Protocol) to the
3211 lib/silcsftp. It includes SFTP client and SFTP server
3214 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3216 * Moved lib/silccore/silcprotocol.[ch] to the
3217 lib/silcutil library.
3219 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
3220 take variable argument list pointer as argument. Affected
3221 file lib/silcutil/silcbuffmt.[ch].
3223 * Added silc_buffer_set function that is used to set data
3224 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
3225 Affected file lib/silcutil/silcbuffer.h.
3227 * Changed various routines in the core library to use the new
3228 silc_buffer_set instead of allocating new buffer only for
3231 * Added 64-bit value formatting and unformatting support to the
3232 silc_buffer_[un]format routines. Affected file is
3233 lib/silcutil/silcbuffmt.[ch].
3235 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
3236 to includes/bitmove.h.
3238 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3240 * Fixed channel user mode saving in client library. Affected
3241 file lib/silcclient/command[_reply].c.
3243 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3245 * Defined the file transfer to the SILC Protocol. Added
3246 new packet type SILC_PACKET_FTP and defined File Transfer
3247 Payload. The mandatory file transfer protocol is SFTP
3248 (SSH File Transfer Protocol). Affected file in addition
3249 of the internet draft is lib/silccore/silcpacket.h.
3251 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
3252 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
3253 is used as part of backup router protocol when the primary
3254 router of the cell is back online and wishes to resume
3255 the position as primary router.
3257 * Redefined the MAC generation keys in the protocol. The
3258 same key is not used anymore in both direction. Both
3259 direction will now use different keys for sending and
3260 receiving. This fixes a potential security flaw. This
3261 change causes incompatibilities in the protocol.
3263 * Redefined also the MAC computation from the packet.
3264 An packet sequence number is now added to the MAC
3265 computation. This prevents possible replay attacks against
3266 the protocol. This change too causes incompatibilities
3269 Added `sequence' field to the SilcPacketContext to hold
3270 the current sequence number for the packet.
3272 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3274 * Added `created' field to the SilcIDListData in the file
3275 silcd/idlist.h to indicate the time when the entry was
3278 * Added `created' field to the SilcChannelEntry too. Affected
3279 file silcd/idlist.h.
3281 * Added `creation_time' aguments to all the announcement functions
3282 in the server. If it is provided then only the entries that
3283 was created after the provided time frame are actually
3284 announced. Affected file silcd/server.[ch].
3286 * The protocol says that the Channel ID's IP address must be
3287 based on the router's IP address. Added check for this in
3288 the silc_server_new_channel when processing incoming New Channel
3289 Payload. Affected file silcd/packet_receive.c.
3291 * Print out the correct version with --version in SILC client.
3292 Affected file irssi/src/silc/core/silc-core.c.
3294 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3296 * Fixed WHOWAS command to check for completnes of the client
3297 entry always, not just when the command is coming from client.
3298 Affected file silcd/command.c.
3300 * Added new function silc_server_packet_queue_purge to purge the
3301 outgoing data queue to the network. After the function returns
3302 it is guaranteed that the outgoing packet queue is empty.
3303 Affected file silcd/packet_send.[ch].
3305 * Purge the outgoing packet queue in the rekey protocol's final
3306 callback to assure that all rekey packets go to the network
3307 before quitting the protocol. Affected file silcd/server.c.
3309 * Added silc_client_packet_queue_parse as similar function as
3310 in server to the client library. The affected file is
3311 lib/silcclient/client.c.
3313 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3315 * Splitted silcd/server.c and created silcd/server_util.[ch]
3316 for utility functions.
3318 * Added new socket flag SILC_SF_DISABLED to indicate that the
3319 connection is open but nothing can be sent to or received from
3320 the connection. Affected file lib/silcutil/silsockconn.[ch].
3321 The checking for disabled socket is checked in the low level
3322 silc_socket_write and silc_socket_read functions.
3324 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3326 * Allow only nicknames and channel names that fits into the
3327 7-bit unsigned char ASCII set. Affected file silcd/command.c.
3329 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3331 * When processing JOIN command reply in server check that if
3332 the channel exists in our global list we'll move it the local
3333 list. Affected file silcd/command_reply.c.
3335 * Fixed the check whether client is joined on the channel already
3336 in JOIN command. Affected file lib/silcclient/command.c.
3338 * Fixed the JOIN command reply to check whether the channel
3339 already exists. Affected file lib/silcclient/command_reply.c.
3341 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3343 * Added silc_ske_status_string to map the SKE error numbers
3344 to readable strings. The affected files are
3345 lib/silcske/silcske[_status].[ch].
3347 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3349 * Do not show the private channels on the WHOIS channel list
3350 as it is not allowed by the protocol. The affected file is
3353 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3355 * Assure that the packet length digged from the actual packet
3356 is something sensible in the silc_packet_decrypt_rest_special
3357 in lib/silccrypt/silcpacket.c.
3359 * Free and NULL the allocated pointer in silc_hmac_alloc if
3360 the HMAC allocation fails. The affected file is
3361 lib/silccrypt/silchmac.c.
3363 * Print the selected security properties to the log files in
3364 the server. Affected file silcd/protocol.c.
3366 * Add SKE's reference counter even if calling the completion
3367 callback manually. Otherwise it goes negative, although it
3368 does not cause any problems. The affected file is
3369 lib/silcske/silcske.c.
3371 * Remove the client entry with short timeout after giving the
3372 KILL command. Affected file lib/silcclient/command.c.
3374 * Fixed to send error reply in WHOIS and IDENTIFY commands in
3375 case all found clients are already disconnected (WHOWAS would
3376 found them) in the server. Affected file silcd/command.c.
3378 * Update the last_receive (time of last data received) to be
3379 updated only when received private or channel message so that
3380 the idle time showed in WHOIS makes more sense.
3382 * Added boolean field `valid' in to the SilcClientEntry in the
3383 client library to indicate whether the entry is valid or not.
3384 This fixes the nickname change bug on channel when changing
3385 the nickname to be same than the old (like nick to Nick) the
3386 nickname formatter doesn't set the new nick anymore to Nick@host.
3387 Affected file lib/silcclient/idlist.[ch].
3389 * Now actually fixed the nickname changing on disconnection.
3390 Added new function silc_change_nick to the Irssi SILC Client.
3391 Affected file irssi/src/silc/core/client_ops.c,
3392 irssi/src/silc/core/silc-nicklist.[ch].
3394 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3396 * Check that the public key exists in the GETKEY command before
3397 trying to encode it. Affected file silcd/command.c.
3399 * Print some notifications on received public keys with GETKEY
3400 command in the Irssi SILC Client. Affected files are
3401 irssi/src/fe-common/silc/module-formats.[ch],
3402 irssi/src/silc/core/client_ops.c.
3404 * Use IDENTIFY command to resolve the server information in the
3405 GETKEY command instead of INFO command. Affected file
3406 lib/silcclient/command.c.
3408 * All command reply functions in the client library now calls
3409 the pending command reply callbacks even if an error has
3410 occurred. The server has done this a long time and now it was
3411 time to move the client library to this as well. Now all
3412 errors can be delivered back to the pending command reply
3413 callbacks if necessary. Affected files are
3414 lib/silcclient/command[_reply].[ch].
3416 * Change the nickname on disconnection back to the username
3417 because in reconnect the server will enforce it to it anyway.
3418 Affected file irssi/src/silc/core/silc-servers.c.
3420 * Fixed a config file parsing bug in the Irssi SILC client.
3421 Affected file irssi/src/silc/core/clientconfig.c.
3423 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3425 * When printing the channel mode on JOIN, verify that the
3426 channel key and channel's HMAC are valid. Affected file
3427 irssi/src/silc/core/client_ops.c.
3429 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3431 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
3432 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
3433 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
3435 * Removed channel key rekey task deleting from the function
3436 silc_server_save_channel_key. Affected file silcd/server.c.
3437 Added explicit timeout task context instead that is used to
3438 delete the task if we are registering a new task before the
3439 new task has elapsed.
3441 * When channel key rekey occurs the client library now saves
3442 the old channel key for a short period of time (10 seconds) and
3443 is able to use it in case some is still sending channel
3444 messages encrypted with the old key after the rekey. Affected
3445 file lib/silcclient/[idlist.h|client_channel.c].
3447 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3449 * Added check to the silc_server_new_id_real to not accept
3450 new ID if it is the sender's own ID. Affected file is
3451 silcd/packet_receive.c.
3453 * Assure that we do not announce ourself or the one we've
3454 sending our announcements when we're router and are announcing
3455 servers to our primary router. Affected file silcd/server.c.
3457 * Fixed silc_server_command_identify_check_client to assemble
3458 correct WHOIS packet. It send corrupted WHOIS packet and
3459 caused problem with router to router connections. Affected
3460 file silcd/command.c.
3462 Fixed also silc_server_command_whois_check the same way
3463 as for the IDENTIFY command.
3465 * Added new SilcIDListStatus to the server in the SilcIDListData
3466 structure. The status now includes the current status of
3467 the entry (like registered, resolved etc.). Affected file
3468 silcd/idlist.[ch]. Defined a bunch of different status types
3469 as well. This replaced the old boolean registered field as well.
3471 Added resolve_cmd_ident field to the SilcClientEntry structure
3472 too so that if the entry is for example being resolved so
3473 another command may attach to the same pending command reply
3474 without requiring to resolve the same entry again. This concept
3475 should optimize the WHOIS and the IDENTIFY resolving under
3476 heavy load by taking away unnecessary resolving for entries
3477 that are being resolved already.
3479 Added support for adding multiple pending commands for one
3480 command idenfier. Affected file silcd/command[_reply].[ch].
3482 * Fixed WHOIS and IDENTIFY save to remove the cache entry
3483 before deleting the data. Otherwise the hash table will have
3484 freed data in comparison functions. Affected file is
3485 silcd/command_reply.c.
3487 * Fixed silc_idlist_replace_client_id to add the new entry to
3488 the cache with NULL nickname. Otherwise there will be invalid
3489 memory as the nickname after the nickname is freed. Affected
3490 file silcd/packet_receive.c.
3492 * Fixed the silc_idlist_get_clients_by_hash. The entries was
3493 saved into wrong slots because the previous number of entries
3494 was not taken into account. Affected file silcd/idlist.c.
3495 Fixed same thing in silc_idlist_get_clients_by_nickname too.
3497 * If we are router and we receive JOIN notify to a channel that
3498 does not have any users then notified client is marked as the
3499 channel founder, as it is it. The affected file is
3500 silcd/packet_receive.c
3502 * Added to the extended hash table API's table_del_*ext functions
3503 the destructor as argument too, so that the caller can decide
3504 which destructor to use or whether to use destructor at all.
3505 Affected file lib/silcutil/silchashtable.[ch].
3507 * Fixed ID Cache purging. It actually deleted the entries from
3508 the hash table after the data was freed. The hash table ended
3509 up comparing freed memory. The affected file is
3510 lib/silccore/silcidcache.c.
3512 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3514 * Fixed Irssi SILC client's KILL command's HELP syntax.
3516 * The USERS command now resolves the detailed user information
3517 if the userinfo field is missing. Affected file is
3518 lib/silcclient/command_reply.c.
3520 * Do not print error in silc_file_read if the read file does
3521 not exist. Just silently return NULL. Affected file is
3522 lib/silcutil/silcutil.c.
3524 * Fixed the silc_log_output to not wine about NULL filename
3525 and to not create some bogus " " filename. Affected file is
3526 lib/silcutil/silclog.c.
3528 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3530 * Fixed various printing bugs on the user interface in the
3531 Irssi SILC Client. Minor changes that were forgotten from
3534 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3536 * Fixed the configure.in.pre and the compilation and distribution
3537 environment to support the new autoconf 2.52. That version is
3538 now required to compile the CVS trunk.
3540 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3542 * Renamed function silc_parse_nickname to silc_parse_userfqdn
3543 to generally parse user@fqdn format strings. Affected file
3544 lib/silcutil/silcutil.c.
3546 * Added nickname_format and nickname_force_format fields to the
3547 SilcClientParams structure. The first one defines the format
3548 for the nicknames that the library will enforce if the receives
3549 multiple same nicknames. The second one is boolean value and
3550 can be used to force the library to always enforce the format
3551 to the nicknames regardles whether there are multiple nicknames
3552 or not. This configurable formatting was employed to flexibly
3553 support accessing multiple nicknames from the user interface.
3554 The userinterface can now set the nicknames to what ever format
3555 they prefer. Affected file lib/silcclient/silcapi.h.
3557 Added function silc_client_nickname_format to the file
3558 lib/silcclient/idlist.c. It performs the nickname formatting.
3560 Added new field `hostname´ to the SilcClientEntry context.
3561 It holds the hostname of the client. Affected file is
3562 lib/silcclient/idlist.h.
3564 * Irssi SILC Client sets the nicknames in nick@hostn format.
3565 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
3566 irssi/src/silc/core/silc-core.c.
3568 The WHOIS printing now also shows both the real nickname and
3569 the formatted nickname so that user knows how to access the
3570 user if there are multiple same nicknames cached. Affected
3571 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
3572 printing formatting too to take the hostname now as a separate
3573 argument. The Affected file is
3574 irssi/src/fe-common/silc/modules-formats.[ch].
3576 * Changed the silc_client_get_clients_local to accept the formatted
3577 nickname as argument. It accepts the real nickname too but the
3578 formatted nickname can be used to find the true entry from
3579 multiple entries. Affected file lib/silcclient/silcapi.h and
3580 lib/silcclient/idlist.c.
3582 * Added nickname_format_parse field to the SilcClientParams.
3583 It is a callback function provided by the application to parse
3584 the nickname out of the formatted nickname string. The library
3585 calls it to get the nickname from the formatted string. Since
3586 the application generally knows better the format of the nickname
3587 string it parses it instead of the library, even though library
3588 encodes the formatted string. If the callback function is not
3589 provided then the library will use the string as is. The
3590 affected file is lib/silcclient/silcapi.h.
3592 * All the nickname strings passed to the client library in
3593 commands are now expected to be formatted nickname strings.
3594 If the command does not support the formatted nickname string
3595 it will assume that the sent string is the actual nickname.
3596 Affected file lib/silcclient/command.c.
3598 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3600 * Added public key authentication support to OPER and SILCOPER
3601 commands in the client library. Affected file is
3602 lib/silcclient/command.c.
3604 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3606 * Changed the get_auth_methdod client operation to be asynchronous.
3607 It can be async if the application resolves the authentication
3608 method from the server during the negotiation. Added new
3609 SilcGetAuthMeth completion callback that the application will
3610 call after resolving the authentication method.
3612 Added function silc_client_request_authentication_method that
3613 the application can use to resolve the authentication method
3614 from the server. Added also SilcConnectionAuthRequest callback
3615 that the library will call after the server has replied. The
3616 application can call this function if it does not know the
3617 current authentication method.
3619 Affected files are lib/silcclient/client.c and
3620 lib/silcclient/silcapi.h.
3622 * The Irssi SILC client now automatically resolves the authentication
3623 method incase any configuration information is not present (and
3624 currently there never is). The affected file is
3625 irssi/src/silc/core/client_ops.c.
3627 * Fixed public key authentication from the client library.
3628 Affected file lib/silcclient/protocol.c. Changed also the
3629 protocol specification about the public key authentication in
3630 the connection authentication protocol. The actual data to be
3631 signed is now computed with a hash function before signing.
3633 * Fixed the public key authentication from the server as well.
3634 Affected file silcd/protocol.c.
3636 * Removed the mlock()'s from the memory allocation routines.
3637 Affected file lib/silcutil/silcmemory.c. The ./configure does
3638 not check anymore for the mlock(). Affected file is
3641 * Fixed USERS command in server to allow the execution of the
3642 command for private and secret channels if the client sending
3643 the command is on the channel. Affected file silcd/command.c.
3645 * Fixed silc_client_get_clients_local to return the clients
3646 count correctly. It could return wrong value. Affected file
3647 lib/silcclient/idlist.c.
3649 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3651 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
3652 types. The assembler optimizations seemed not to like 64-bit
3653 data types. The assmebler optimizations thus are now enabled
3654 also for BSD systems as opposed to only enable them for Linux.
3656 * Do not check for threads at all on BSD systems. Affected
3657 file configure.in.pre.
3659 * Removed -n and -h options from the Irssi SILC Client since
3660 they are not used in silc.
3662 * Fixed the prime generation to assure that the first digit
3663 of the generated random number is not zero since our conversion
3664 routines does not like number strings that starts with zero
3665 digit. If zero digit is seen the random number is regenerated.
3666 This caused some corrupted RSA keys when the zero first digit
3667 was met. Affected file lib/silcmath/silcprimegen.c.
3669 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3671 * Fixed WIN32 configuration in the ./configure script.
3672 Fixed to include xti.h on environments that has it.
3673 Patches by Carsten Ilchmann and andrew.
3675 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3677 * Changed the silc_id_create_client_id to be collision
3678 resistant. It is now assured that there cannot be created
3679 two same client ID's. I suspect that some weird bugs in
3680 the server were actually caused by duplicate Client IDs.
3681 Affected file silcd/serverid.[ch]. A router receiving
3682 new ID now also assures and informs the sending server
3683 if the ID caused collision.
3685 * Changed the silc_id_create_channel_id to also assure that
3686 there are no collisions.
3688 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3690 * Statement about ignoring the Mutual Authentication flag when
3691 performing rekey with PFS was a bit misleading. It is ignored
3692 if it was set in the initial negotiation, it cannot be even
3693 set in the rekey. Fixed in the ke-auth draft. Started the
3694 new versions of the protocol drafts in the doc/.
3696 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3698 * Fixed a bug in silc_client_command_identify_save when saving
3699 new channel information. The channel name was no duplicated
3700 and caused crash on exit. Affected file is
3701 lib/silcclient/command_reply.c.
3703 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3705 * Fixed the getkey command handling in the server. Send just
3706 empty OK reply to the sender if the key could not be fetched
3707 (but everything else was ok, like the key just was not available).
3708 Changed the public key parameter to optional in the protocol
3709 specs so that empty OK reply can be sent. Affected file
3712 Added a message to Irssi SILC client to tell to user if the
3713 server did not return a public key.
3715 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3717 * Fixed a channel key regeneration bug. It registered new
3718 timeout tasks exponentially until all system resources were
3719 used. Affected file silcd/server.c.
3721 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3723 * Added the SILC Document generator to the scripts/silcdoc.
3724 It can be used to generate the Toolkit Reference Manual out
3725 of the source tree. Internally it will also use the RoboDoc
3726 generator now imported in util/robodoc.
3728 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3730 * Added couple of return's in rekey protocol if error orccurred
3731 during the protocol. The execution must be terminated.
3732 Affected file silcd/protocol.c. Also, terminate the protocol
3733 always with timeout.
3735 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3737 * The client's Client ID was created initally from the wrong
3738 nickname (it could have been in format nick@host) in the
3739 silc_server_new_client. Affected file silcd/packet_receive.c
3741 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3743 * Added some SILC_LOG_ERROR's to various error conditions
3744 if client could not be added to ID cache. Affected files
3745 silcd/packet_receive.c and silcd/server.c.
3747 * When client's sock->user_data is freed, NULL also the
3748 client->router and client->connection pointers. Added check
3749 for these pointers being NULL to various places around the
3750 code. Affected file silcd/server.c.
3752 * Added client->data.registered == TRUE checks to various
3753 places around the code to assure that unregistered client's
3754 are not handled when it is not allowed. Affected file
3757 * Added `bool registered' fields to all
3758 silc_idlist_[server|client]_get_* routines to indicate whether
3759 the fetched client needs to be registered or not. Affected
3760 file silcd/idlist.[ch].
3762 * Add your own entry as registered to the ID cache in the
3763 server. Affected file server.c.
3765 * Fixed a bug in silc_server_new_server. The SilcServer was
3766 set as the new server's context instead of SilcServerEntry.
3767 This naturally caused some weird bugs.
3769 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3771 * Do not delete the channel rekey task when adding it
3772 for in silc_server_create_channel_key.
3774 * Changed the silc_server_create_channel_key to return
3775 TRUE or FALSE to indicate the success of the channel key
3778 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3780 * Fixed MSVC++ project files and added missing files to
3781 Makefiles under win32/.
3783 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3785 * Do not add TCP_NODELAY flag if the operating system
3786 does not have it defined. Affected files are
3787 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3789 * Fixed buffer overflow from Irssi SILC Client. Affected
3790 file irssi/src/fe-common/core/themes.c.
3792 * Fixed double free in client library in the file
3793 lib/silcclient/client.c when disconnecting from server.
3795 * Applied double free patch from cras to Irssi SILC client.
3796 Affected files irssi/src/core/[modules/expandos].c
3798 * Fixed the disconnection handling to Irssi SILC Client.
3799 The application must call silc_client_close_connection
3800 in ops->connect client operation in case of failure of
3801 the connection. Affected file is
3802 irssi/src/silc/core/client_ops.c.
3804 * Do not set sock->protocol to NULL in the function
3805 silc_client_close_connection after executing the protocol's
3806 final callback since the sock might not be valid anymore.
3807 Affected file lib/silcclient/client.c.
3809 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3811 * Do not enable SILC_THREADS if the linking with libpthread
3812 did not happen. Affected file configure.in.pre.
3814 * Added notion to protocol specification that server must
3815 verify the sent authentication payload with CMODE when
3816 setting the channel founder key. Implemented it to the
3817 server. Affected file silcd/command.c.
3819 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3821 * Added _EXTRA_DIST SILC distribution variable to the
3822 distributions file. It is used to conditionally add extra
3823 files or directories to the specific distribution. Affected
3824 files ./prepare, Makefile.am.pre and distributions.
3826 Removed the `_' from the start of the distribution names.
3829 * Added README.WIN32 for instructions to compile the Toolkit
3832 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3834 * Fixed a double free in disconnection in the server. Affected
3835 file is silcd/server.c.
3837 * Fixed the lib/silcske/groups.c to work now also with GMP
3838 MP library. The string conversion did not work when using
3839 specific base and the base is indicated in the string as well.
3841 * Created win32/ directory which now includes MSVC++ specific
3842 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3843 It will appear only in the toolkit distribution
3845 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3847 * Changed the key material distribution function in case when
3848 the hash output is too short. The data is now concatenated
3849 a bit differently than it used to. Made the change to the
3850 SKE protocol specification.
3852 * Added better GMP detection to configure.in.pre. A patch
3855 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3857 * Fixed a minor bug in SKE that might cause some problem on
3858 some platforms. Affected file lib/silcske/silcske.c.
3860 * Added the cookie checking for initiator in the SKE. It checks
3861 that the responder returns the sent cookie unmodified. The
3862 affected file is lib/silcske/silcske.c. Added new SKE
3863 error type INVALID_COOKIE that can be sent during the
3864 negotiation. Fixed some memory leaks as well.
3866 * Added the "invalid cookie" error message to Irssi SILC client's
3869 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3871 * Added `task_max' field to the SilcClientParams to indicate
3872 the maximum tasks the scheduler can handle. If set to zero,
3873 default values are used. Affected file lib/silcclient/silcapi.h.
3875 * Fixed memory leaks in silc_client_close_connection. Affected
3876 file lib/silcclient/client.c.
3878 * Added silc_client_del_client_entry to client library to free
3879 all memory of given client entry. Affected file is
3880 lib/silcclient/idlist.[ch].
3882 * Added new functions silc_client_del_channel and
3883 silc_client_del_server to delete channel and server entries.
3884 Affected file lib/silcclient/[silcapi.h/idlist.c].
3886 * Removed silc_client_del_client_by_id from silcapi.h.
3888 * Fixed the INFO command to return the server's own info
3889 correctly when querying by Server ID. Affected file is
3892 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3894 * Removed the non-blocking settings in WIN32 code in the
3895 silc_sock_[read/write] and added SleepEx instead. Affected
3896 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3897 of input data is now checked with FIONREAD and ioctlsocket.
3899 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3901 * Call silc_schedule_task_del_by_context in the
3902 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3903 Affected file lib/silccore/silcprotocol.c.
3905 * Call silc_protocol_cancel for active protocols in the
3906 silc_server_close_connection if the funtion
3907 silc_server_free_sock_user_data has not been called.
3908 Affected file silcd/server.c.
3910 * Generic tasks cannot be deleted using the del_by_fd
3911 task deleting function since generic tasks does not match
3912 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3914 * Added a notion to SILCOPER help file that the SILCOPER works
3915 only on router server, not on normal server.
3917 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3919 * Added for WIN32 support for the new scheduler as well.
3920 Affected file lib/silcutil/win32/silcwin32schedule.c.
3922 * Fixed the SHA1 implementation to work on various platforms.
3924 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3926 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3927 API. It is part of the scheduler now. Everything else is
3928 as previously but some functions has changed their names.
3929 Checkout the lib/silcutil/silcschedule.h for the interface.
3930 Updated all applications to use the new interface. Affected
3931 files are lib/silcutil/silcschedule.[ch].
3933 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3935 * Found a bug in the SKE implementation. The HASH value,
3936 specified by the protocol, was not computed correctly. The
3937 public key of the responder was not added to the computation
3938 even though it is mandatory. Affected file lib/silcske/silcske.c.
3939 This unfortunately causes incompatibilities with older
3940 clients and servers.
3942 * Added WIN32 specific network init and uninit functions:
3943 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3944 the Winsock2. Affected file lib/silcutil/silcnet.h and
3945 lib/silcutil/win32/silcwin32net.c.
3947 * Set the socket always to nonblocking mode on WIN32 after
3948 reading data or writing data. Affected file is
3949 lib/silcutil/win32/silcwin32sockconn.c.
3951 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3953 * Fixed various compilation problems under WIN32. Affected
3954 files lib/silcutil/win32/silcwin32thread.c and
3955 lib/silcutil/win32/silcwin32schedule.c.
3957 * Removed all _internal.h #includes from public header
3958 files. Internal headers must never be included from
3961 Removed also the lib/silcske/payload_internal.h file.
3963 * All include files that may be needed (public and some others
3964 included by the public headers) by application developers are
3965 now copied to the ./includes directory. It does not copy any
3966 internal headers. Affected file Makefile.defines.pre and all
3967 Makefile.am's under lib/ and subdirs.
3969 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3971 * Do not change the ~/.silc directory's permissions automatically.
3972 Affected file irssi/src/silc/core/clientutil.c.
3974 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3976 * Do not cancel the protocol in silc_server_close_connection
3977 it might cause recursion. Now cancelled in the function
3978 silc_server_free_sock_user_data. Affected file silcd/server.c.
3980 * Fixed the silc_server_remove_clients_by_server to regenerate
3981 the channel keys correctly finally. Added also new function
3982 silc_server_remove_clients_channels to actually do it.
3983 Affected file silcd/server.c.
3985 * Fixed the silc_server_new_channel to not crash by giving
3986 wrong router to the new channel. Affected file is
3987 silcd/packet_receive.c.
3989 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3991 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3992 which is given as argument to the silc_client_alloc now.
3993 It can be used to configure the client and set various parameters
3994 that affect the function of the client.
3996 * The USERS command in server did not check whether the channel
3997 is private or secret. Affected file silcd/command.c.
3999 * Added new argument to the USERS command in protocol specification.
4000 The USERS command now can take the channel name as argument
4001 as well. Added support for this in client and server and
4002 updated the protocol specs.
4004 * Completed the GETKEY command in client. It can be now used
4005 to fetch also servers public key not only some clients.
4006 Affected files lib/silcclient/command[_reply].c.
4008 * Added silc_client_get_server to return server entry by the
4009 server name. Affected files lib/silcclient/silcapi.h and
4012 * Redefined the IDENTIFY command in protocol specification to be
4013 more generic. It now can be used to query information about
4014 any entity in the SILC Network, including clients, servers and
4015 channels. The query may be based either the entity's name
4016 or the ID. Added support for this in both client and server.
4018 Affected files silcd/command.c and lib/silcclient/command.c
4019 and command_reply.c.
4021 * Optimized the WHOIS and WHOWAS commands in the server. Removed
4022 the _from_client and _from_server functions. Affected file
4025 * Added silc_client_get_channel_by_id_resolve to the file
4026 lib/silcclient/silcapi.h to resolve channel information by
4027 its ID. Added also silc_client_get_channel_by_id that
4028 does not resolve it from the server.
4030 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4032 * Added SilcServerEntry context into the client library
4033 to represent one server. The INFO command now allocates
4034 these to save the resolved server info. For now on the
4035 client library will also keep information about servers,
4036 connected and resolved with INFO.
4038 The INFO command now allocates the SilcServerEntry context
4039 and saves the server info there. The COMMAND_REPLY in
4040 the INFO now returns the parameters to application in
4041 same order as defined in the protocol specification.
4043 The entries are cached in the client->server_cache.
4045 * The INFO command is now issued after received the Client ID
4046 from the server. Affected file lib/silcclient/client.c.
4048 * The CMODE_CHANGE notify may now return also an SilcServerEntry
4049 to the application as the mode changer might be server.
4050 It is guaranteed that NULL is not returned anymore to the
4051 application. Affected file lib/silcclient/client_notify.c.
4053 The ID Type is now also passed to the application so that
4054 it can check whether the returned entry is SilcClientEntry
4057 Added new function silc_client_get_server_by_id to return
4058 the server entry by ID. Affected files are the
4059 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
4061 * Do not create the channel in the Irssi SILC Client when issuing
4062 the JOIN command but when received the sucessful JOIN command
4063 reply. Otherwise the channel might get created even though we
4064 could not join it. The Affected file is
4065 irssi/src/silc/core/[silc-channels.c/client_ops.c].
4067 * Fixed a channel joining bug in router. The router must also
4068 check the channel modes, invite and ban lists etc. when serving
4069 the JOIN command sent by normal server. Affected file is
4070 silcd/command.c. The router now resolves the client's
4071 information from the server who sent the JOIN command if it
4072 does not know it, and processes the JOIN command only after
4075 * Changed the SilcCommandCb to take new argument; void *context2.
4076 Affected file lib/silccore/silccommand.h
4078 The second argument in the command callbacks in the server now
4079 includes the SilcServerCommandReplyContext if the command was
4080 called as pending command callback from the command reply.
4081 Otherwise it is NULL. When called as pending the status of the
4082 command reply will be checked and if it was erronous the
4083 error will be sent to the original sender of the command.
4084 This way the client always receives the error messages even
4085 though the server was actually the one who received the error
4086 when it resent the command to router, for example. Affected
4087 files silcd/command[_reply].[ch].
4089 * Fixed sending WHOWAS command's error message to client if
4090 the requested client could not be found. It was missing.
4093 * Changed the CMODE and CUMODE commands reply arguments in the
4094 protocol specification. The Channel ID is now sent in both
4095 of the commands to identify the channel. Implemented this
4096 new feature to the client and server. Affected files
4097 lib/silcclient/command_reply.c and silcd/command.c.
4099 * Made better checks for invite and ban lists in the JOIN
4100 command in server. Affected file silcd/command.c.
4102 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4104 * The server now performs the incoming host IP/DNS lookup
4105 using the silc_socket_host_lookup and thus does not block
4106 the server anymore. Affected file silcd/server.c.
4108 * Completed the multi-thread support for SILC Scheduler in
4109 the lib/silcutil/silcschedule.c.
4111 * Fixed the configure.in.pre to detect the pthread correctly
4114 * Fixed a deadlock in silc_task_queue_wakeup in the file
4115 lib/silcutil/silctask.c.
4117 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4119 * Added new function silc_schedule_wakeup that is used in
4120 multi-threaded environment to wakeup the main thread's
4121 schduler. It needs to be used when a thread adds a new task
4122 or removes a task from task queues. After waking up, the
4123 scheduler will detect the task queue changes. If threads
4124 support is not compiled in this function has no effect.
4125 Implemented the wakeup mechanism to both Unix and WIN32
4126 systems. Affected files are lib/silcutil/silcschedule.[ch],
4127 lib/silcutil/unix/silcunixschedule.c and the
4128 lib/silcutil/win32/silcwin32schedule.c.
4130 * Added new function silc_task_queue_wakeup to wakeup the
4131 scheduler by the specified task queue. Affected file
4132 lib/silcutil/silctask.[ch].
4134 * The silc_socket_host_lookup_start now wakes up the scheduler
4135 after adding the timeout task. Affected file is
4136 lib/silcutil/silcsockconn.c.
4138 * The silc_socket_host_lookup is synchronous now if the threads
4139 support is not compiled in. However, the callback is still
4140 called asyncronously through the scheduler, anyway. Affected
4141 file lib/silcutil/silcsockconn.c.
4143 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4145 * Added new function silc_socket_host_lookup to perform
4146 asynchronous IP and FQDN lookups for the socket connection.
4147 Affected files lib/silcutil/silcsockconn.[ch].
4149 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4151 * Added SILC_MUTEX_DEFINE to define the mutex on environments
4152 that may or may not compile the mutex support in.
4154 Changed the silc_mutex_alloc interface. It allocates the
4155 mutex now to the sent pointer and returns TRUE or FALSE.
4157 Affected file lib/silcutil/silcmutex.h.
4159 * Wrote the SILC Task Queue interface to support multi-threads.
4160 Affected file lib/silcutil/silctask.[ch].
4162 * Wrote the SILC Scheduler to support multi-threads. Affected
4163 file lib/silcutil/silcschedule.c.
4165 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4167 * Implemented the SILC Mutex API and SILC Thread API for WIN32
4168 in lib/silcutil/win32/.
4170 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4172 * Defined SILC Mutex API and SILC Thread API and implemented
4173 them for Unix. Affected files are
4174 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
4175 lib/silcutil/unix/silcunixmutex.c and
4176 lib/silcutil/unix/silcunixthread.c.
4178 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4180 * Fixed the silc_server_remove_clients_by_server's channel
4181 key re-generation. The hash table handling was incorrect
4182 and would not work with many channels. Affected file is
4185 * Fixed some memory leaks around the server code.
4187 * Rewrote the silc_server_get_users_on_channel to support IPv6
4188 based Client ID's. Affected file silcd/server.c.
4190 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
4191 specification. However, a separate document must be written
4192 to define the detailed signing procedure and the payload
4193 associated with the flag. Defined the flag to the
4194 lib/silccore/silcchannel.h as well.
4196 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4198 * Changed the dynamic tables to static size tables in the
4199 lib/silccrypt/silchmac.c.
4201 * Removed GCC dependencies from the code. A patch by cras.
4203 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4205 * Do not show the error "Error receiving packet bla bla"
4206 in server if it really was not an error (-2 means that reading
4207 is pending). Affected file silcd/server.c.
4209 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4211 * Fixed a possible crash in silc_server_remove_clients_by_server
4212 in silcd/server.c. Fixed there also some memory leaks.
4214 * Fixed the silc_idlist_replace_client_id. It could replace
4215 wrong key in the hash table. Affected file silcd/idlist.c.
4217 * Do not check whether there are global users on the channel
4218 if the channel->global_users is FALSE. Affected functions
4219 silc_server_remove_from_one_channel and
4220 silc_server_remove_from_channels in silcd/server.c. Also,
4221 do not check if the removed client is local as we can be
4222 sure that global client was not removed from the channel
4223 and checking for global users is not needed.
4225 * The silc_server_remove_clients_by_server now re-generates
4226 the channel keys correctly for those channels that had
4227 clients removed from them. Affected file silcd/server.c.
4229 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4231 * Found the reason of random crashes in the server. We weren't
4232 ignoring the SIGPIPE signal (which can be sent in write())
4233 and it crashed the server. Affected file silcd/silcd.c.
4235 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4237 * Assure that sock->user_data is not NULL in the function
4238 silc_server_packet_send in silcd/packet_send.c.
4240 * Disconnect the remote connection if it could not be added
4241 to any ID lists in the server. The affected file is
4244 * Check in silc_server_packet_send[_real/dest] that the
4245 socket is not disconnecting and ignore the data if it is.
4246 Affected file silcd/packet_send.c.
4248 * Define inline to __inline on native WIN32 compilation.
4249 Affected file includes/silcwin32.h.
4251 * Added some explicit type casts for inline code since MSVC
4252 require them. Affected files lib/silcutil/silcbuffer.h,
4253 lib/trq/silcdlist.h and lib/trq/silclist.h.
4255 * Print warning in log files from now on if the packet
4256 decryption fails. Affected file silcd/server.c.
4258 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4260 * Changed the `say' client operation's interface to accept
4261 new `type' argument to indicate the type of the message sent
4262 by the library. The application may filter the library's
4263 messages according the type. The affected file is the
4264 lib/silcclient/silcapi.h.
4266 * Added two new functions to lib/silcclient/silcapi.h:
4267 silc_client_del_client and silc_client_del_client_by_id.
4268 Affected file lib/silcclient/idlist.c.
4270 * Moved the clientincludes.h from includes/ to silc/ and
4271 serverincludes.h from includes/ to silcd/.
4273 * The modes for the CMODE and CUMODE are now passed as
4274 uint32 for application with COMMAND_REPLY. The affected
4275 file is lib/silcclient/command_reply.c.
4277 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4279 * /WHOIS without arguments shows client's own information.
4280 Affected file lib/silcclient/command.c.
4282 * Changed PING to not accept any arguments. The specs
4283 says that client can ping only the connected server so
4284 requiring an argument is not needed. Affected file is
4285 lib/silcclient/command.c.
4287 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4289 * Fixed a fatal bug in private message sending and reception
4290 encryption and decryption when using private message keys.
4291 The implementation was incorrect and did not follow the
4292 specification. It causd that some of the message were
4293 lost since it did not use the sending and receiving keys
4294 as the protocol suggests. This has been fixed and will cause
4295 incompatibilities with older clients when sending private
4296 message encrypted with private message keys. Affected files
4297 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
4298 and various other in Irssi SILC Client.
4300 Added `responder' boolean argument to the functions
4301 silc_client_add_private_message_key[_ske] to indicate when
4302 the key is added as responder or initiator of the key
4305 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4307 * Removed the silc_ske_check_version function and created
4308 a SilcSKECheckVersion callback. Added also a function
4309 silc_ske_set_callbacks that is now used to set all SKE
4310 callbacks. The callback functions are not given to
4311 the SKE functions anymore, but this function is used to
4314 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
4316 * Added `silc_version' argument to the silc_client_alloc
4317 to define the version of the application for the library.
4318 The library will use the version string to compare it
4319 against the remote host's (usually a server) version
4320 string. Affected file lib/silcclient/silcapi.h
4322 * Added the KE protocol context to Key Agreement context
4323 in client library so that we can abort the SKE if it
4324 is in process when we get timeout. Affected file is
4325 lib/silcclient/client_keyagr.c.
4327 * Do not resolve the client ID forever if it returns in the
4328 first time that such client does not exist. This was done
4329 for example with private message. Affected file is
4330 lib/silcclient/client_prvmsg.c.
4332 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4334 * Do not add regex.h for WIN32. The affected file
4335 includes/silcincludes.h.
4337 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
4338 not work yet 100%. It generates the DLL's automatically
4339 when compiling with --with-win32 under cygwin.
4341 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4343 * lib/contrib/regex.c is not compiled on WIN32.
4345 * Added silc_net_get_socket_opt function to the
4346 lib/silcutil/silcnet.h.
4348 * Added includes/silcwin32.h for WIN32 specific includes
4351 * Do not use ptime structure or any of the posix process
4352 functions on WIN32 in lib/silccrypt/silrng.c.
4354 * Added silc_gettimeofday to provide generic function
4355 for struct timeval on all platforms. Added the function
4356 to lib/silcutil/silcutil.h.
4358 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4360 * Moved the lib/silccore/silcsockconn.[ch] to the utility
4361 library as they clearly belong there. As a plus side we
4362 can make the actual socket connection routines platform
4365 Added also new generic function silc_socket_read and
4366 silc_socket_write (that used to be silc_packet_[read/write].
4367 The implementation of these are platform specific.
4369 * Added WIN32 specific routines of silc_socket_[read/write]
4370 to lib/silcutil/win32/silcwin32sockconn.c.
4372 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4374 * Added preliminary support for native WIN32 compilation under
4375 cygwin (using the -mno-cygwin option for GCC) to the
4376 ./configure.in.pre. The --with-win32 now prepares the
4377 compilation for native WIN32.
4379 * Rewrote the SILC Scheduler interface in the file
4380 lib/silcutil/silcschedule.h. The scheduler is now context
4381 based and does not have anymore any global static scheduler.
4382 Moved the Unix scheduler to the lib/silcutil/unix/ directory
4383 and created lib/silcutil/win32 directory for WIN32 based
4386 * Added Unix specific network routines to the
4387 lib/silcutil/unix/silcunixnet.c and the old
4388 lib/silcutil/silcnet.c includes now only generic routines.
4390 Added WIN32 specific network routines to the
4391 lib/silcutil/win32/silcwin32net.c.
4393 * Added Unix specific utility functions from the
4394 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
4396 * Added WIN32 SILC Scheduler to the file
4397 lib/silcutil/win32/silcwin32schedule.c. The code is of course
4400 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4402 * Do not handle JOIN notify in the server if the target client
4403 is not registered (idata->registered == FALSE). The affected
4404 file is silcd/packet_receive.c.
4406 * Update the nickrec->founder in event_cumode in the Irssi SILC
4407 client. Affected file irssi/src/silc/core/silc-channels.c.
4409 * Fixed the CUMODE_CHANGE notify handling in the server when
4410 server and router are announcing their clients on channels.
4411 Now the mode changes are saved and notified correctly. The
4412 affected file is /silcd/packet_receive.c.
4414 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
4415 They really did not replace the cache entry in the ID Cache.
4416 Now they do that. Affected file silcd/idlist.c.
4418 * Fixed the KICK notify handling in the Irssi SILC client to
4419 update the channel records so that the kicked client does not
4420 appear to be on the channel. The affected file is
4421 irssi/src/silc/core/silc-channels.c.
4423 * Always update the conn->current_channel when executing command
4424 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
4426 * Fixed the KILL notify handling in Irssi SILC client to remove
4427 the killed client on all channels.
4429 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4431 * Fixed the silc_parse_command_line to remove extra spaces
4432 from the start and end of the arguments. Affected file is
4433 lib/silcutil/silcutil.c.
4435 * Cancel and free any active protocol in the function
4436 silc_server_close_connection. Affected file silcd/server.c.
4438 * Cancel and free any active protocol in the function
4439 silc_client_close_connction. Affected file is
4440 lib/silcclient/client.c.
4442 * Do not execute the KILL command for clients that are in
4443 history (ie. they are not in the network). Affected file is
4446 * Fixed KILL notify handling, client does not crash anymore.
4447 Affected file irssi/src/silc/core/silc-channels.c.
4449 * Reduced the default packet buffer size from 2048 to 1024 in
4450 lib/silccore/silcpacket.c.
4452 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
4453 counter to the SKE context that is incresed when the SKE library
4454 performs async operation outside the library. If the outside
4455 process frees the SKE context and FREED status will be set
4456 and the library will detect after the sync operation that the
4457 libary is freed. The affected files are
4458 lib/silcske/silcske[_status].[ch].
4460 * Resolve the client entry information in the function
4461 silc_client_channel_message to assure that NULL pointer is not
4462 passed as client entry to the application. */
4464 * Fixed the task timeout calculation to assure that there is
4465 never negative timeouts. The affected file is
4466 lib/silcutil/silcschedule.c.
4468 * Fixed the channel user mode notification sending in server.
4469 It was sent point-to-point to the router (or to server by router)
4470 but it needs to be destined to a channel. The routines now
4471 supports sending the channel user mode notifys to the channels
4472 when announcing clients and channels. Affected files are
4473 silcd/server.c and silcd/packet_receive.c.
4475 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
4476 It did not actually replace the old channel entry in the cache.
4477 Affected file lib/silcclient/client_notify.c.
4479 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4481 * Fixed a possible crash in silc_packet_send_prepare. It now
4482 assures always that there is enough space in the buffer and
4483 at the tail area of the buffer (for MAC).
4485 Fixed the inbound buffer reallocation in silc_packet_read.
4486 It was old code and did not handle the reallocation correctly.
4489 The affected file is lib/silccore/silcpacket.c.
4491 * Fixed buffer overflow in silc_parse_nickname in the file
4492 lib/silcutil/silcutil.c.
4494 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4496 * make install generates new server keys only if there is not
4499 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4501 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
4502 Added check that if the NOREPLY is set then we will not send
4503 the away message. This avoids infinite loop of away messages
4504 if both clients are away. The affected file is
4505 lib/silcclient/client_prvmsg.c.
4507 * Fixed client crash if /NICK was given without arguments.
4508 Affected file lib/silcclient/command.c.
4510 * Server does not send the invite list in INVITE command back
4511 to the client if the list was not altered. Added this notion
4512 to the protocol spec as well. Affected file silcd/command.c.
4514 Fixed possible crash in INVITE command by checking the
4515 value of silc_server_get_client_route command.
4517 * Fixed the INVITE notify type handling. The arguments are now
4518 taken in correct order and client does not crash. The affected
4519 file is irssi/src/silc/core/silc-channels.c.
4521 Removed the "Inviting xxx to channel" message from the
4522 client library away and let the application handle it.
4523 Affected file lib/silcclient/command.c. Added that message
4524 to Irssi SILC client's message formats.
4526 * Fixed CMODE command crash in client. It now checks the
4527 amount of arguments correctly and does not crash. The affected
4528 file is lib/silcclient/command.c.
4530 * Do not create new channel automatically in silc_channels_join
4531 but check whether the channel by that name already exists.
4532 Affected file irssi/silc/core/silc-channels.c.
4534 * Do not send the SERVER_SIGNOFF to router if the disconnected
4535 entity was the router. Affected file silcd/server.c.
4537 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
4538 SILC client as it was missing from there.
4540 Added the handling of the KICK notify to the Irssi SILC client
4541 as it was missing. Added "you have been kicked" message to
4542 Irssi SILC client's message modules formats.
4544 Added the handing of the KILL notify to the Irssi SILC client
4545 as it was missing. Added the kill message module formats
4548 The affected file is irssi/src/silc/core/silc-channels.c.
4550 * The router did not save the channel mode the server announced.
4551 Affected file silcd/packet_receive.c.
4553 * Fixed a possible crash in INFO command in server. If the
4554 server did not provide the server info it crashed. Affected
4555 file silcd/command.c.
4557 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4559 * Fixed the GETKEY command in the server to check also the
4560 global list. Otherwise the GETKEY would not work correctly
4561 in normal SILC server. Affected file silcd/command.c.
4563 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4565 * Fixed GETKEY crash, it crashed if the command did not succseed.
4567 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4569 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
4570 is now real and not just an macro interface to GMP.
4572 Removed the entire GMP from the source tree and imported new
4573 NSS MPI library instead. Reason for removing GMP is that it is
4574 extremely large and compiles extremely slow. The NSS MPI
4575 is only a few files and compiles in less than 10 seconds.
4576 The speed is also about the same as GMP. The MPI is imported
4577 to lib/silcmath/mpi.
4579 If the system has GMP installed we will still use the GMP.
4580 If it is not then the NSS MPI will be compiled.
4582 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4584 * Merged a long nickname (127 characters long) crash bugfix from
4585 Irssi CVS tree. Affected file irssi/src/core/misc.c.
4587 * Merged a freed memory reference bugfix from Irssi CVS tree.
4588 Affected file irssi/src/core/commands.c.
4590 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4592 * Added the server's public key sving and verification to the
4593 server when performing the SKE. This was missing and the
4594 remote server's (or router's) public key was accepted without
4595 checking whether we have it previously or trust it at all.
4596 Affected file silcd/protocol.c.
4598 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4600 * Check in the silc_server_timeout_remote if protocol is active
4601 and make sure that the protocol's final callback is called so
4602 that all memory if freed. Affected file silcd/server.c.
4604 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4606 * silc_server_whois_send_reply crashed the server if the nickname
4607 was 127 characters long. Affected file silcd/command.c.
4609 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4611 * Added sanity check to the silc_server_new_client. If the hostname
4612 is provided inside username then check that the provided hostname
4613 really is the same as the resolved one. If the hostname was not
4614 resolved then check it from the public key. Affected file is
4615 silcd/packet_receive.c.
4617 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
4618 if the server disconnected us and the connection is not valid
4619 anymore. Affected file irssi/src/silc/core/silc-channels.c.
4621 * Moved the silc_client_[chmode|chumode|chumode_char] away from
4622 the library to the lib/silcutil/silcutil.[ch].
4624 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4626 * Close log file after open. Affected file
4627 lib/silcutil/silclog.c.
4629 * Check whether sock == NULL in silc_client_send_packet and return
4630 if it is. Affected file lib/silcclient/silcclient.c.
4632 * Check rec->entry == NULL in the Irssi SILC Client before
4633 sending the channel message. Affecte file is
4634 irssi/src/silc/core/silc-servers.c.
4636 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4638 * Merged a splitted window bugfix from Irssi CVS tree. The
4639 affected file is irssi/src/fe-text/textbuffer-view.c.
4641 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
4642 It did not print nickname.
4644 * Improved the distributions system a bit.
4646 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4648 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
4649 irssi/src/fe-text/gui-window.c.
4651 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
4652 to in-active server. The affected file is
4653 irssi/src/silc/core/client_ops.c.
4655 * Resolve the client in USERS command reply if the entry does
4656 not have username resolved. The affected file is
4657 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
4658 command to WHOIS command to really resolve stuff. The USERS
4659 is not used any more in any critical section so WHOIS can
4660 be used even though it might be slower than IDENTIFY.
4662 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
4665 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4667 * Changed the protocol API a bit more consistent in the
4668 lib/silccore/silcprotocol.[ch].
4670 * Changed the following headers to ROBODoc format:
4672 lib/silccore/silcpayload.h
4673 lib/silccore/silcprotocol.h
4674 lib/silccore/silcsockconn.h
4676 All core library headers are now formatted.
4678 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4680 * Fixed a bug in Irssi SILC client; do not show that you are
4681 server/router operator if you really are not. Affected file is
4682 irssi/src/silc/core/client_ops.c.
4684 * Renamed silc_command_free_payload to silc_command_payload_free.
4685 Affected file lib/silccore/silccommand.h
4687 * Added silcmath.h to include the prototoypes of various routines
4688 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
4691 * Changed the following headers to ROBODoc format:
4693 lib/silccore/silcchannel.h
4694 lib/silccore/silccommand.h
4695 lib/silccore/silcid.h
4696 lib/silccore/silcidcache.h
4697 lib/silccore/silcmode.h
4698 lib/silccore/silcnotify.h
4699 lib/silccore/silcpacket.h
4700 lib/silcmath/silcmath.h
4702 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4704 * Added checking to the server code not to start the server if
4705 ciphers and stuff are not configured properly. Affected files
4706 silcd/serverconfig.[h] and silcd/server.c.
4708 * Changed the layout of the header files of the public interfaces
4709 in the SILC libraries. The new layout supports ROBODoc
4710 documentation tool (and some others) so that it is easy to create
4711 a library reference manual. All the other headers and source
4712 code must still follow the CodingStyle document. Also source
4713 code must not include these ROBODoc stuffs, only the headers.
4714 Furthermore, all public interface headers must now be named
4715 by using `silc' prefix, example: silcapi.h, silccipher.h.
4716 Some files were renamed due to this. All the other headers
4717 must not be used as public interfaces. I will update the
4718 CodingStyle document later. Changed following headers, so far:
4720 lib/silcclient/silcapi.h
4721 lib/silccore/silcauth.h
4722 lib/silccore/silcprivate.h
4723 lib/silccrypt/silcdh.h
4725 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4729 * Removed silc_client_packet_send_flush from the client library
4730 as it is not needed. Affected file lib/silcclient/client.[ch].
4732 * Added printing of message of unresolved authentication method
4733 to the Irssi SILC client. Added it to the module formats.
4734 Removed the same message from the client library.
4736 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4738 * Added new distribution feature, DISTLABEL. Every distribution
4739 can define own preprocessor label that can be used in the
4740 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
4741 file distributions, acconfig.h.pre and prepare.
4743 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4745 * Added Makefile.defines_int to include the actual definitions
4746 for Makefile.defines.in. Tested the new distribution system,
4747 created distributions and tested installation.
4749 * Added AWAY message printing to the Irssi SILC client. Added
4750 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
4752 * Added SCONNECT command to call the SILC's CONNECT command.
4753 Cannot use CONNECT directly since Irssi uses that internally.
4754 Affected file irssi/src/silc/core/silc-servers.c.
4756 Added ACTION local command. It is same as ME command but takes
4757 the channel as mandatory argument.
4759 Rewrote some of the Irssi's help files to suite for SILC
4762 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4764 * Added Makefile.defines[.in] that should for now on be included
4765 in all Makefile.am file in the source tree. That file includes
4766 all common compilation definitions for SILC source tree.
4768 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4770 * Minor changes to the ./prepare script to change the package
4771 name according the distribution name to the configure.in.
4773 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4775 * Created new distribution system. Added file `distributions'
4776 that defines all the distributions that can be created out of
4777 the SILC source tree. The ./prepare script now reads that
4778 file to determine how to prepare the distributions. The
4779 first argument to the ./prepare is the name of the distribution
4780 and second is the version of the distribution. If given
4781 without arguments it creates the default (toolkit) distribution
4782 with the default version (defined in ./prepare).
4784 All Makefile.am files that are subject to the distributions
4785 are now named as Makefile.am.pre. These are ./Makefile.am
4786 and lib/Makefile.am. Others may be changed later.
4788 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4790 * Added invite list, ban list, some key management and connection
4791 error message printing to module formats in the Irssi SILC client.
4793 * Added new silc_client_set_away_message to set the away message
4794 that is back to the person who sent private message. The
4795 affected file lib/silcclient/silcapi.h and the
4796 lib/silcclient/client_prvmsg.c.
4798 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4800 * Fixed the private message sending in the Irssi SILC client,
4801 added local command KEY to the Irssi SILC client.
4803 Added key management and key agreement message formats to the
4804 irssi/src/fe-common/silc/module-formats.[ch].
4806 Added USERS (alias WHO) printing, server/router operator
4807 indication and LIST command printing to the module formats.
4809 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4811 * Fixed channel joining notify handling, cumode notify handling
4812 from Irssi SILC client.
4814 * Added SILC specific module-formats to the Irssi SILC client so
4815 that SILC specific message hilighting, colors etc is possible.
4816 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4818 Added channel mode, channel user mode, actions, notices,
4819 whois and whowas printing to the the module-formats.c.
4821 * Fixed a bug in channel deletion in the server. The channel
4822 is not left to the cache even if the channel founder auth mode
4823 is set when there are no users anymore on the channel. Affected
4824 file silcd/server.c.
4826 * The silc_net_localhost now resolves the entire hostname including
4827 the domain name. Affected file lib/silcutil/silcnet.c.
4829 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4831 * Changed the ask_passphrase client operation to be ascynchronous.
4832 It has now a completion callback and a context that the
4833 application must call after it has got the passphrase from
4834 the user. Affected files lib/silcclient/silcapi.h,
4835 lib/silcclient/protocol.c, lib/silcclient/command.c and
4838 Added SilcAskPassphrase callback that the application calls
4839 to deliver the passphrase to the library.
4841 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4842 The public key verification and especially a certificate
4843 verification is asynchronous procedure.
4845 Added new SILC_SKE_STATUS_PENDING status to indicate the
4846 request is pending and a callback will be called to finalize
4849 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4850 indicate that remote end did not send its public key (or
4851 certificate), even though we require it. Added check for this
4852 condition in the SKE. This was a security bug, now fixed.
4854 Defined new SilcSKEVerifyCbCompletion callback that is called
4855 when the verification process is completed.
4857 The affected files lib/silcske/silcske_status.h and
4858 lib/silcske/silcske.[ch].
4860 * Changed the verify_public_key client operation to be async
4861 as well. Defined SilcVerifyPublicKey callback that is used to
4862 indicate the success of the public key verification process.
4864 Changed the server and client to use the new async client
4867 * Changed the Irssi SILC client's internal scheduler to be called
4868 twice as many times as it used to be. As a result the client
4869 should be a bit faster now. Affected file is
4870 irssi/src/silc/core/silc-core.c.
4872 * Added support to Irssi SILC client of asynchronous public key
4873 verification and passphrase inquiry. Affected file is
4874 irssi/src/silc/core/silc-core.c.
4876 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4878 * Do not say "You have left channel %s" in client library.
4879 Moved it to the application. Affected files are
4880 lib/silcclient/command.c and silc/client_ops.c.
4882 * Fixed silc_client_get_clients. Command context was not
4883 duplicated and was freed memory in the callback. Affected
4884 file lib/silcclient/idlist.c.
4886 * Do not say "you are now talking..." on JOIN command in the
4887 client library. The appliation must handle it.
4889 * Do not say ".. changed topic to" in command reply in the
4890 client libary. The application must handle it.
4892 * Fixed TOPIC command sending in the client library.
4894 * Fixed a memory leak in silc_client_command_free in the file
4895 lib/silcclient/command.c.
4897 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4899 * Imported a modified version of Irssi client to the source tree.
4900 The Irssi will be used to create a new client called
4901 Irssi SILC. Imported to irssi/.
4903 Added silc_core_init_finish function to the Irssi. Affected
4904 file irssi/configure.in.
4906 A lot changes in the Makefile.ams around the irssi tree.
4908 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4910 * Do not rehash if the new size is same as the old size of the
4911 hash table, in the silc_hash_table_rehash*. The affected file
4912 lib/silcutil/silchashtable.c.
4914 * Replaced hash_table_del_by_context calls from the server
4915 (when channel->user_list and client->channels) to the
4916 hash_table_del as it is sufficient and faster.
4918 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4920 * Added silc_hash_table_list, silc_hash_table_get and the
4921 SilcHashTableList structure to provide an alternative way to
4922 traverse the hash table. The affected files are
4923 lib/silcutil/silchashtable.[ch].
4925 * Changed the server's idlist routines to use the hash table
4926 routines to optimize the code.
4928 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4930 * Replaced the client entry's `channel' list and channel entry's
4931 `user_list' list to hash tables for optimized lookup. Changed
4932 the code to use the hash table interface around the code.
4933 Affected file lib/silcd/idlist.[ch].
4935 * Added `auto_rehash' boolean argument to the function
4936 silc_hash_table_alloc to indicate whether the hash table should
4937 auto-rehash when it thinks is appropriate time. It will
4938 increase the hash table size if the there is twice as much
4939 entries in the table than the size of the table, and will
4940 decrease the size if there are twice as less entries than
4941 the size of the table.
4943 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4945 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4947 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4949 * silc_idcache_purge_by_context deletes the entry now by context
4950 as it is supposed to do. Affected file lib/silccore/idcache.c.
4952 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4953 client is not anymore valid (WHOWAS givens the info) and not
4954 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4956 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4958 * Removed the `data' and `data_len' arguments from the ID Cache
4959 interfaces and added `name' argument. ID Cache does not handle
4960 anymore the binary data only a names associated with given ID.
4962 * When hashing a Client ID with silc_hash_id the entire ID is
4963 not hashed anymore, instead only the hash of the Client ID is
4964 hashed. This way we can access the Client ID from the cache
4965 with Client ID but with the hash of the ID (which is a hash of
4966 the nickname) as well without any difference in performance.
4968 Added also silc_idcache_find_by_id_one_ext to do one on one
4969 searching when we have the actual ID. Added also function
4970 silc_hash_client_id_compare. The affected files are
4971 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4973 * When hashing the name associated with a ID it is always done
4974 in lowercase. This way we can access the cache without worrying
4975 about case-sensitivity, even though, for example nicknames are
4978 * Fixed a bug in server with channel message sending. It put
4979 wrong ID type as destination ID. The affected file
4980 silcd/packet_send.c.
4982 * silc_idcache_del_by_context now deletes from all hash tables
4983 by context. Affected file lib/silccore/idcache.c.
4985 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4987 * Changed the client library to use the new ID Cache interface.
4988 Changes around the source tree.
4990 * Added silc_hash_table_rehash_ext to rehash with specific
4991 hash function. Affected file lib/silcutil/silchashtable.[ch].
4993 * Added silc_hash_string_compare to compare two strings in the
4994 hash table. Affected file lib/silcutil/silcutil.[ch].
4996 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4998 * Added new function silc_idcache_del_by_context into the
4999 lib/silccore/idcache.[ch].
5001 * Changed the server's ID list routines to use the new ID Cache
5002 interface. Changes around the source tree.
5004 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5006 * Added silc_hash_table_del[_by_context]_ext functions in to the
5007 lib/silcutil/silchashtable.[ch].
5009 Removed silc_hash_table_find_all* routines and added new
5010 silc_hash_table_find_foreach to replace them.
5012 Added silc_hash_table_replace_ext function as extended
5013 replacing function. Separated the simple hash table interface
5014 from the extended hash table interface in the file
5015 lib/silcutil/silchashtable.h.
5017 * Fixed minor bugs and changed it to use some of the new
5018 hash table functions in lib/silccore/idcache.c
5020 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5022 * Added new function silc_hash_table_find_all to return all keys
5023 in the hash table by the specified key. As the hash table is
5024 collision resistant it also makes it possible to have several
5025 duplicate keys in the hash table. This function may be used to
5026 find all of the keys from the hash.
5028 Added user_context arguments to the SilcHashFunction,
5029 SilcHashCompare and SilcHashDestructor to deliver user specified
5032 Added new fuctions silc_hash_table_find[_all]_ext to do
5033 extended lookup with specified hash and compare functions and
5034 specified user contexts.
5036 Added new function silc_hash_table_add_ext to add the key
5037 with specified hash function and user context.
5039 Added new function silc_hash_table_foreach to traverse all
5040 entrys in the hash table. Added SilcHashForeach callback
5043 Added new function silc_hash_table_del_by_context to delete
5044 the entry only if the context associated with the key matches.
5046 Affected files are lib/silcutil/silchashtable.[ch].
5048 * Removed silc_hash_[server/client/channel]_id and added just
5049 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
5050 silc_hash_id_compare to compare two ID's using as the hash table
5051 comparison function. Added also silc_hash_data to hash
5052 binary data and silc_hash_data_compare to compare it.
5054 * Removed silc_idlist_find_client_by_hash as it is not needed
5055 anymore. Affected file silcd/idlist.[ch].
5057 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
5058 to use internally the SilcHashTable. The new ID Cache is a lot
5059 faster than the old one. Some of the ID Cache interface was also
5060 rewritten and obsolete and stupid functions were removed.
5062 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5064 * Added entry_count field to the SilcHashTable to keep the number
5065 of the entries in the table. Implemented the function
5066 silc_hash_table_rehash. Added new function
5067 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
5069 Fixed a minor bug in silc_hash_table_free.
5071 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
5072 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
5073 into the lib/silcutil/silcutil.[ch].
5075 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5077 * Implemented a collision resistant hash table into the
5078 lib/silcutil/silchashtable[ch]. See the header and the source
5079 for the SilcHashTable API.
5081 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5083 * Merged dotconf version 1.0.2 into lib/dotconf.
5085 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5087 * Do not compile anything in lib/silcsim/* if the SIM support
5088 is not enabled. The tree should now compile without problems
5091 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5093 * Compiled the SILC under cygwin. Compiled and tested briefly
5094 without problems. More tests needed. The SIMs didn't compile
5097 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
5099 * Fixed possible crash in silc_get_username in the
5100 lib/silcutil/silcutil.c.
5102 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5104 * Fixed a va_arg in silc/client_ops.c.
5106 * Oops, RC5 routines were named AES and caused some problems
5107 when not using SIM's. Affected file lib/silccrypt/rc5.c.
5109 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5111 * Added new SilcIDIP structure into the lib/silccore/id.h and
5112 replaced the old `ip' fields from all SILC ID's to that type.
5113 This is a step towards IPv6 support.
5115 The silc_id_get_len takes now the ID as an extra argument.
5116 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
5117 both IPv4 and IPv6 based ID's.
5119 The affected files are lib/silccore/id.[ch] and other files
5120 around the tree using these routines.
5122 * Removed the ID length arguments in server from various
5123 silc_server_send_notify_* routines -> they are not needed
5126 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5128 * Fixed memory leak in silc_encode_pem_file in the file
5129 lib/silcutil/silcutil.c.
5131 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5133 * Check minor version as well in the SKE. Affected files are
5134 silcd/protocol.c and lib/silcclient/protocol.c.
5136 * Added --identifier option to the server so that an identifier
5137 can be when creating the public key for the server. Affected
5138 file is silcd/silcd.c.
5140 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
5141 lib/silccrypt/silcpkcs.c.
5143 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5145 * Register default ciphers and stuff when using -C option with
5146 the server. Affected file sildc/silcd.c.
5148 * Put back the servers public key filename format, it is better
5149 than the new one. For now, the client keys are saved with the
5150 new filename format. The affected file silc/client_ops.c.
5152 * Implemented the Cipher API for the rest of the ciphers that
5153 did not implement it or implemented it the wrong way.
5155 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5157 * Register default ciphers and stuff when using the -S option
5158 in the client. Affected file silc/silc.c. Same also when
5159 creating new key pair with -C option.
5161 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5163 * Fixed the silc_verify_public_key client operation function to
5164 save the public keys differently. The fingerprint is now
5165 used as filename and not the hostname. This way also the
5166 client keys are saved uniquely and not with hostnames. The
5167 affected file is silc/client_ops.c.
5169 * Trimmed the silc_hash_fingerprint function to remove extra
5170 whitespaces from the end of the fingerprint. The affected
5171 file is lib/silccrypt/silchash.c.
5175 * Added silc_cipher_register_default function to register all
5176 default ciphers. It can be used when configuration files
5177 does not exist and the application does not want any specific
5178 ciphers in any specific order.
5180 The SilcDList is now used as silc_cipher_list dynamically
5181 allocated cipher list. Removed the static list all together
5182 and now all ciphers must be allocated to the dynamic list.
5183 The silc_cipher_alloc routine was changed to check only the
5186 All silc_cipher_* routines that used to return int returns
5189 The affected files lib/silccrypt/silccrypt.[ch].
5191 * The same thing was done to silc_hash_* as for silc_cipher_*
5192 routines. Affected files lib/silccrypt/silchash.[ch].
5194 * The same thing was done to silc_pkcs_* as for silc_cipher_*
5195 routines. Affected files lib/silccrypt/silcpkcs.[ch].
5196 Added also silc_pkcs_[un]register[_default] functions.
5197 Removed the data_context from the PKCS API.
5199 * Added silc_hmac_register_default function to register default
5200 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
5201 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
5202 to unregister all hmacs at once.
5204 * Register the default ciphers, hash functions, PKCSs and HMACs
5205 if client's configuration file does not exist. The affected
5208 * The client did not load the hash functions from the SIM
5209 modules at all. Added support for this. Affected file is
5210 silc/clientconfig.c.
5212 * When decoding public key with silc_pkcs_public_key_decode, check
5213 the supported algorithm only if PKCS are registered. Affected
5214 file lib/silccrypt/silcpkcs.c. The same was done with the
5215 silc_pkcs_private_key_decode.
5217 * Fixed the SILC List routines to keep the list always in order.
5218 It used to change the list's order when traversing the list but
5219 not it preserves the order. Affected file lib/trq/silclist.h.
5221 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5223 * Added the client library to use the SilcSocketConnection's
5224 reference counter (by silc_socket_dup) to prevent the bug that
5225 the socket object may be freed underneath async operation.
5227 * The name resolv library checking fixes in the configure.in.pre.
5230 * Created new version of the protocol drafts for future
5231 development. The -03 drafts are the ones that will be changed
5232 in the trunk now and the -02 will remain as they are.
5234 * Send list of CUMODE notifys to the router when announcing
5235 the channel users to the router. Affected file silcd/server.c.
5236 If the router receiving channel founder CUMODE for a channel
5237 that already has channel founder it will send CUMODE notify
5238 to the sender to remove the channel founder rights from the
5239 announced client. Affected file silcd/packet_receive.c.
5241 * The CUMODE notify may now use Server ID as well as the entity
5242 who changes the mode. Updated protocool specs.
5244 * Updated INSTALL and README files.
5246 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5248 * New web pages in the http://silc.pspt.fi. The pages was
5253 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5255 * Implemented the [DenyConnectin] config section in the server.
5256 Added silc_server_config_denied_conn to check whether incoming
5257 connection is denied. Affected file silcd/serverconfig.[ch].
5259 * Do not check the ports when checking the incoming configuration
5260 data if the port is 0, meaning any. Affected file is
5261 silcd/serverconfig.c.
5263 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5265 * Fixed buffer overflow in silc_string_compare in the file
5266 lib/silcutil/silcutil.c.
5268 * Fixed double free in silc_server_command_leave in the file
5271 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5273 * Fixed the version checking in the server. Affected file is
5276 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5278 * Fixed the configuration data fetching when accepting new
5279 connections in the server. Affected file silcd/server.c.
5281 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5283 * Added `sender_entry' argument to the function
5284 silc_server_packet_relay_to_channel so that we can check
5285 whether some destination actually belongs to the same route
5286 the sender belongs (ie, we must not resend the packet to the
5287 sender). Affected file silcd/packet_send.[ch].
5289 * Added `servername' field to the SilcClientEntry in the server
5290 to hold the name of the server where client is from. Affected
5291 file is silcd/idlist.h.
5293 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5295 * Moved the channel message encrypting in the router betwen
5296 router connections from silc_server_channel_message to the
5297 silc_server_packet_relay_to_channel since we want to check
5298 whether we have anybody channel before encrypting anything.
5299 Affected files silcd/packet_[receive/send].c.
5301 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5303 * Fixed the [AdminConnection] server config section to support
5304 multiple entries. Affected file silcd/serverconfig.c.
5306 * Added support into the server to check the validity of the
5307 incoming connection before executing any KE or authentication
5310 * The connection configuration is now saved to the KE and
5311 connection auth protocol contexts and not fetched anymore in
5312 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
5314 * The local hosts listenning address and port is also resolved
5315 now when starting the server. We want to have the socket object
5316 to include the real address and port for the listener. Added
5317 new function silc_net_check_local_by_sock into the files
5318 lib/silcutil/silcnet.[ch].
5320 * Fixed a broadcast bug in server -> do not broadcast if we
5323 * Fixed a routing bug. Do not route broadcast packets ever.
5324 Broadcast packets must be processed always and not routed since
5325 they may be destined to some other host than yourself and thus
5326 would get routed without no good reason. Affected file is
5329 * Added function silc_server_config_is_primary_route to check
5330 whether primary router connection has been configured (a router
5331 configuration that we are initiating). If there is not, we
5332 will assume that there is only two routers in the SILC network
5333 and we will use the incoming router connection as our primary
5334 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
5336 * Changed the order of the broadcasting. Broadcast _after_ the
5337 packet has been processed not before. Affected file is
5340 * Fixed a [ClientConnection] parsing bug. The port was never
5341 parsed correctly thus resulting to port 0. Affected file
5342 silcd/serverconfig.c.
5344 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
5345 argument and did not set the broadcast packet flag. Affected
5346 file silcd/packet_send.c. Fixed same bug in the function
5347 silc_server_send_notify as well.
5349 * If we receive NEW_ID packet for our own ID in the server, ignore
5352 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5356 * Removed the nickname from the Private Message Payload.
5357 Updated the code and the protocol specs.
5359 * Updated protocol specs for submitting to the IETF.
5361 * Tweaked the Random Number Generator a bit. Affected file
5362 lib/silccrypt/silcrng.c. Exported a new function
5363 silc_rng_[global]_add_noise which can be used to add more
5366 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5368 * Do not parse packets with different timeout when protocol
5369 is active -> may cause problem with rekey. Affected file
5372 * When server receives signoff notify it must not create
5373 new channel key if the client is on any channels since the
5374 sender of the signoff notify will create it.
5376 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5378 * Added printing of error messages during SKE protocol from the
5379 failure packet sent by server during SKE. Affected file
5382 * Removed the client's failure_callback handling with timeout
5383 and handle it immediately when received.
5385 * The SKE library returned wrong type in SUCCESS and FAILURE
5386 packets. They must be 32 bit MSB not 16 bit MSB.
5388 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5390 * Ok, rewrote the logic of the re-key and now it seems to work.
5391 I tested it on high traffic with frequent re-keys without
5392 problems. Added hmac_receive (and renamed hmac to hmac_send)
5393 in SilcClientConnection in lib/silcclient/client.h and
5394 in SilcIDListData in silcd/idlist.h. Also, removed the
5395 SilcPacketParserContext's cipher and hmac fields as they are
5396 not needed anymore and actually caused some problems when
5397 the ciphers and hmac's changed underneath the packet parser.
5399 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5401 * If re-key protocol is active then process the incoming packets
5402 synchronously since we must assure that icoming packets encrypted
5403 with the old key is processed before the new keys is set to
5404 use. This is true other packets than for REKEY packets.
5405 Affected file silcd/server.c. The same was done to client library
5406 as well, affected file lib/silcclient/client.c.
5408 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5410 * Fixed bug in client and server to accept the force send if
5411 the packet is send from silc_[server/client]_packet_process
5412 function. Otherwise the packets are never delivered, oops.
5414 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5416 * Disable force sending of packets when REKEY protocol is active.
5417 We must assure that no packet is sent directly when rekey is
5418 performed. All packets must be sent through packet queue.
5419 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
5420 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
5421 function is silc_[server/client]_packet_send_real to check
5424 * Replaced the SIM paths from example config files to
5425 /usr/local/modules. Also, make install creates now
5426 /usr/local/silc/logs directory to hold all the SILC server
5429 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5431 * Made the configure.in.pre work on Solaris. Patch by salo.
5433 * Made all ciphers compatible with non-x86 machines. Defined
5434 CBC mode macros into lib/silccrypt/ciphers_def.h.
5436 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5438 * Fixed the make install.
5440 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5442 * When MAC computation fails the silc_packet_decrypt returned 0
5443 even though it was supposed to return -1. Fixed this. The
5444 affected file is lib/silccore/silcpacket.c.
5446 * Do not replace the config files in /etc/silc (in make install)
5447 if they already exist. Affected file ./Makefile.am.
5449 * Do not send re-key packets immediately but through packet queue.
5450 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
5452 * Changed silc_net_check_host_by_sock to return FALSE if the
5453 IP/DNS could not be resolved. Though, it returns the IP address
5454 now even if it could not resolve it (but returns also FALSE).
5455 Affected file lib/silcutil/silcnet.[ch].
5457 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5459 * Added silc_pkcs_decode_identifier to decode the public key's
5460 identifier. Affected file lib/silccrypt/silpkcs.[ch].
5461 Added also silc_pkcs_free_identifier. Added also new context
5462 SilcPublicKeyIdentifier.
5464 * Added -S option to the silc client. It is used to dump the
5465 contents of the specified public key file.
5467 * Changed the PKCS api to return the public key length when
5468 setting the public key.
5470 * Fixed a fatal bug in the public and private key file loading.
5471 Affected file lib/silccrypt/silcpkcs.c.
5473 * Execute the packet parsing for client with zero (0) timeout
5474 if the protocol is active. Affected file silcd/server.c.
5476 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5478 * Made the key generation options to the silcd program. Added
5479 -C option, equivalent to client's option.
5481 * Added new [ServerKeys] config section to the server. It
5482 configures the server's public and private key.
5484 * Defined generic Public Key Payload into the protocol
5485 specification to send specific type of public keys and
5488 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
5489 public key or certificate.
5491 * Implemented the GETKEY command to the server and to the
5492 client library and on user interface.
5494 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5496 * Made preliminary `make install' work.
5498 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5500 * Added SilcServerRekey context into silcd/idlist.h.
5502 * Added the PFS support as defined in the specification to the
5503 SKE protocol. Affected files lib/silcske/*.c.
5505 * Added `ske_group' field to the SilcServerRekey context to hold
5506 the number of the SKE group that is used with PFS in re-key.
5507 Affected file silcd/idlist.h.
5509 * Added PFS re-key support to the server. Affected file is
5512 * Added silc_protocol_cancel to cancel execution of the next
5513 state of the protocol. Affected file is
5514 lib/silccore/silcprotocol.[ch].
5516 * Added the re-key support with and without PFS to the client
5517 library. Re-key is performed once in an hour, by default.
5519 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
5520 Added silc_client_rekey_callback and silc_client_rekey_final.
5521 Affected files are lib/silcclient/protocol.[ch] and
5522 lib/silcclient/client.[ch].
5524 * Removed the `hmac_key' and `hmac_key_len' fields from the
5525 SilcClientConnection structure; not needed. Affected file is
5526 lib/silcclient/client.h.
5530 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5532 * Do not ask whether user wants to use the negotiated private key
5533 for private messages, just use it. Affected file is
5534 silc/local_command.c.
5536 * Added `send_enc_key' and `enc_key_len' fields to the
5537 SilcIDListData structure since they are needed in the re-key
5538 phase. Affected file is silcd/idlist.[ch].
5540 * Implemented the simple re-key protocol into the server.
5541 Affected files silcd/server.c and silcd/protocol.[ch]. The
5542 re-key will be performed once in an hour, by default.
5544 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
5545 Added silc_server_rekey, silc_server_rekey_callback and
5546 silc_server_rekey_final.
5548 * Removed Tunneled flag from the protocol. Updated the code
5549 and the specifications.
5551 * Adde `pfs' field to the SilcIDListData to indicate whether
5552 the PFS is to be performed in the re-key. Affected file is
5555 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5557 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
5558 int64 of at least the xintXX size. If void * is less that 4
5559 bytes uint32 * will be used. Defined bool as boolean.
5561 * Changed _ALL_ unsigned long and unsigned int to uint32,
5562 unsgined short to uint16 in the source tree.
5564 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
5565 not handle clients that has entry->data.registered == FALSE.
5566 They are not in the network anymore. Affected file is
5569 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5571 * Implemented the sending of the SERVER_SIGNOFF notify in the
5572 server. Affected file is silcd/server.c.
5574 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
5575 Added also silc_notify_payload_encode_args into the
5576 lib/silccore/silcnotify.[ch].
5578 * Implemented ther SERVER_SIGNOFF notify handling in the server.
5579 Affected file silcd/packet_receive.c.
5581 * Implemented the SERVER_SIGNOFF notify handling in the client
5582 library. Affected file lib/silcclient/client_notify.c. Also,
5583 implemnted the printing of the SERVER_SIGNOFF info to the
5584 application. Affected file silc/client_ops.c.
5586 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
5587 if the deleting was successful. Affected file silcd/idlist.[ch].
5589 * Added support for public key authentication in the connection
5590 authentication protocol in the client library. Affected file
5591 lib/silcclient/protocol.c.
5593 * Changed the server's silc_idlist_get_clients_by_* interface
5594 to support already allocated array so that new entries may be
5595 added to pre-allocated array. Affected file silcd/idlist.[ch].
5596 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
5597 and command replies.
5599 * All command reply functions in the server now calls the
5600 pending command callback even if error occured. This way the
5601 error will be delivered to the client as well. Affected files
5602 silcd/command.c and silcd/command_reply.c.
5604 * Fixed INFO command to return local server's info if no server
5605 was provided. Affected file lib/silcclient/command.c.
5607 * Removed RESTART command for good. Updated the code and the
5610 * Rewrote parts of the task system. It is a bit simpler now.
5611 Removed unsued task priorities. The affected files are
5612 lib/silcutil/silctask.[ch].
5614 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5616 * Moved the USERS printing from the library to the application.
5617 Affected files lib/silcclient/command.c and silc/client_ops.c.
5619 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5623 * Added channel key re-key support. The re-key is perfomed
5624 only by the router and is done once in an hour. Added `rekey'
5625 field to the SilcChannelEntry in the server. Affected files
5626 silcd/server.c and silcd/idlist.h.
5628 * Added silc_task_unregister_by_context into the file
5629 lib/silcutil/silctask.[ch].
5631 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5633 * Added SILC_UMODE_GONE mode to indicate when the client is not
5634 present in the SILC network. Added also support to the local
5635 command AWAY that will set this mode. Added support of showing
5636 "xxx is gone" in WHOIS command. The USERS command shows the
5637 gone status as well.
5639 * Fixed setting server and router operator privileges in the
5640 server's UMODE command. Affected file silcd/command.c.
5642 * Merged the SKE KE1 and KE2 payloads into one payload. The
5643 new KE payload is equivalent to the old KE2 payload.
5645 Cleaned up the SKE Start Payload parsing. It now uses the
5646 simple buffer unformatting to do the parsing. A lot faster
5649 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
5650 to the SKE that is used to indicate whether both of the SKE
5651 parties should perform authentication. By default only the
5652 responder performs authentication. By setting this flag also
5653 the initiator must do authentication. By default it is unset
5654 since in normal SKE case, client to server connection, only
5655 the responder should do authentication. When doing SKE between
5656 two clients both should perform authentication. Updated the
5657 code and the protocol specs.
5659 * A little fix to IDENTIFY command in the server. Search the
5660 client first by hash not nickname. Affected file is
5663 * Fixed the silc_client_close_connection to support closing
5664 the client to client connections wihtout deleting too much
5665 data. Affected file lib/silcclient/client.c.
5667 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
5668 are received if protocol used to be active but is not anymore
5669 the application would crash due to NULL pointer dereference.
5670 Affected files silcd/server.c and lib/silcclient/client.c.
5672 * Added `hash' field to the SilcClientConnection to include
5673 the hash function negotiated in the SKE protocol.
5675 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
5676 to set the channel founder authentication data. A client can
5677 claim the founder rights later by providing the authentication
5678 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
5679 This way the channel founder can regain the channel founder
5680 privileges even it is left the channel. This works only on
5681 local server and the client must be connected to the same
5682 server to be able to regain the founder rights. Updated the
5683 protocol specs accordingly.
5685 Added support to the CMODE command in the client to set the
5686 founder auth data. Read the README to see how to set it.
5688 Added support to the CUMODE command to claim the founder
5689 rights. Read the README to see how to do it.
5691 Added support for the founder authentication to the Channel
5692 Entry in the server. Affected file silcd/idlist.h.
5694 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
5695 server's CMODE command. Affected file silcd/command.c.
5697 * Added the following new functions into lib/silccore/silcauth.[ch]:
5698 silc_auth_get_method and silc_auth_get_data.
5700 * The server now saves the remote hosts public key to the
5701 SilcIDListData pointer. Affected file silcd/protocol.c.
5703 * The normal server now does not remove the channel entry from
5704 the cache if the founder authentication data is set. It used
5705 to remove it if the founder was the last one on the channel on
5706 the server and left the channel. The auth data is saved and
5707 if the channel is re-joined later the old entry is used with
5708 the old auth data. Affected files silcd/command_reply.c and
5711 * Removed the `pkcs' field from the SilcIDListData structure
5712 in the server; it is not used. Affected file silcd/idlist.h.
5714 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5716 * Fixed packet processing on slow links. Partial packets were
5717 never re-processed because the incoming data buffer was cleared
5718 by the application. Application must not directly clear the
5719 sock->inbuf, the packet processing routines handle it. Fixed
5720 this in client library and in server.
5722 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5724 * Fixed the WHOIS and IDENTIFY send reply function to really
5725 check whether to send list or just one entry. Affected file
5728 * Cleaned up the LEAVE command's channel key distribution. The
5729 affected file silcd/command.c.
5731 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
5732 can enforce the channel mode as well. In that case the ID
5733 includes the ID of the server. The code now enforces the
5734 mode change if the router have different mode than the server.
5736 * The notify client operation with CMODE_CHANGE notify can now
5737 return NULL client_entry pointer if the CMODE was not changed
5738 by client. Application must check for this.
5740 * Added <Server ID> argument to INFO command to support server
5741 info fetching by Server ID.
5743 * Added silc_server_announce_get_channel_users to get assembled
5744 packets of channel users of the specified channel. Affected
5745 file silcd/server.[ch].
5747 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
5748 was freed underneath the ID Cache.
5750 * Re-announce clients when the server received CHANNEL_CHANGE
5751 notify from the router. Affected file silcd/packet_send.c.
5753 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5755 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
5756 crashed since it did not handle the fact that there is no cipher
5757 called "3" and didn't check the error condition. Now fixed.
5759 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
5760 flag. It can be used to send message requests.
5762 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5764 * Implemented the RESTART command in the client.
5766 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
5767 notice type messages. Added notice printing to the user
5770 * The channel keys are not re-generated if the channel's mode
5771 is PRIVKEY, ie private key on the channel exists. Affected
5772 files silcd/server.c and silcd/command.c.
5774 * Fixed a little bug in channel message delivery when channel
5775 private keys are set in the server. Affected file is
5776 silcd/packet_send.c.
5778 * Changed the setting on channel->on_channel = TRUE from the
5779 silc_client_save_channel_key to the JOIN command reply. The
5780 key payload is not received if the private channel key is set.
5781 Affected file lib/silcclient/command_reply.c and the
5782 lib/silcclient/client_channel.c.
5784 * When the CMODE_CHANGE notify is sent and the channel private
5785 key mode is removed the channel key must be re-generated in
5786 other cells as well. Added this support for the router in the
5787 silcd/packet_receive.c.
5789 * Added new local command NOTICE to send notice message on
5790 channel. Affected file silc/local_command.[ch].
5792 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5794 * Added new local command ME to the client. It is used to send
5795 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
5796 some action. Affected file silc/local_command.[ch].
5798 * Changed channel_message and private_message client operations
5799 to deliver the message flags to the application. Added also
5800 the `flags' arguments to the silc_client_send_channel_message
5801 and silc_client_send_private_message functions. Affected file
5804 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5806 * Redefined the Private Message Payload to support private message
5807 keys and to support the new private message flags. Updated
5808 the protocol specs. Flags makes it possible to have for example
5809 CTCP style messages.
5811 * Added new type SilcPrivateMessagePayload and defined an API
5812 for it in the lib/silcclient/silcprivate.[ch].
5814 * Tested private message private keys successfully. Tested the
5815 private message key set, unset and list commands with the new
5818 * Redefined the Channel Message Payload to include the channel
5819 message flags (equal with private message flags) to support
5820 for example CTCP style messages.
5822 * Defined some of the message (for channel and private message)
5823 flags. Updated the protocol specs and added the flags to the
5824 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5826 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5828 * Added SilcKeyAgreementStatus type to the key agreement routines
5829 to indicate the current status and error if one occured.
5830 The status types are defined in the lib/silcclient/silcapi.h.
5832 * Added new local command KEY that is used to set and unset private
5833 keys for channels, set and unset private keys for private messages
5834 with remote clients and to send key agreement requests and
5835 negotiate the key agreement protocol with remote client. The
5836 key agreement is supported only to negotiate private message keys,
5837 it currently cannot be used to negotiate private keys for channels,
5838 as it is not convenient for that purpose.
5840 * Fixed a minor pending callback setting bug in the function
5841 silc_client_get_client_by_id_resolve, now the function works.
5842 Affected file lib/silcclient/idlist.c.
5844 * Added function silc_net_get_local_port to get local bound
5845 port by socket. Added to lib/silcutil/silcnet.[ch].
5847 * Added `sockets' and `sockets_count' fields to the SilcClient
5848 object. They hold the sockets of the listenning sockets in
5849 the client. Listenning sockets may be for example the key
5850 agreement server. Affected file lib/silcclient/client.[ch].
5851 Added functions the silc_client_add_socket and the
5852 silc_client_del_socket. They are exported to the application
5855 * Added ~./silc/clientkeys to support other client's public keys.
5857 * Renamed verify_server_key client operation to verify_public_key
5858 and added one argument to indicate the type of the connection
5859 (server, client etc.).
5861 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5863 * Added silc_server_connection_auth_request to handle the
5864 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5865 silcd/packet_receive.[ch].
5867 * Added silc_server_send_connection_auth_request into the
5868 silcd/packet_send.c to send the connection auth request packet.
5870 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5873 * Fixed the public key authentication in responder side in the
5874 server. The `auth_data' pointer includes the SilcPublicKey
5875 not the path to the public key. Affected file silcd/protocol.c.
5877 * Implemented the public key authentication in the initiator side
5878 in the server. Affected file silcd/protocol.c.
5880 * Removed the [RedirectClient] config section from the server
5881 configuration. Is not needed and I don't want to implement it.
5883 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5885 * Cleaned up the CMODE command in the server. It now works
5886 correctly and supports all the modes defined in the protocol.
5887 Affected file is silcd/command.c.
5889 * Added `hmac_name' field to the SilcChannelEntry in the server
5890 to hold the default HMAC of the channel. It can be set when
5891 creating the channel (with JOIN command). Affected files
5894 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5895 type to indicate the change of the current cipher and hmac
5896 on the channel. Client can safely ignore the <cipher> argument
5897 (if it chooses to do so) since the CHANNEL_KEY packet will
5898 force the channel key change anyway. The <hmac> argument is
5899 important since the client is responsible of setting the new
5900 HMAC and the hmac key into use.
5902 * Fixed the CMODE command in the client library as well.
5904 * Tested CMODE command in router environment successfully.
5906 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5908 * Show the version of the remote client (or server) when connecting
5909 to the server. It is logged to the log file. Affected file
5910 is silcd/protocol.c.
5912 * Fixed the KILLED notify handling in the client library. The
5913 client must be removed from all channels when receiving the
5916 Also, do not remove the client entry when giving the KILL
5917 command but when the KILLED notify is received.
5919 * Removed silc_idlist_find_client_by_nickname from the server.
5920 Not needed anymore. Affected files silcd/idlist.[ch].
5922 * Implemented the CHANNEL_CHANGE notify type handling to the
5923 server. Affected file silcd/server.c.
5927 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5929 * Added silc_server_send_notify_invite to send the INVITE
5930 notify between routers.
5932 * Implemented the INVITE command correctly to the server.
5934 * Implemented the INVITE notify type handling in the server.
5936 * Implemented the INVITE command to the client library and on the
5939 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5941 * Added function silc_server_get_client_resolve to find the
5942 client entry by ID from all ID lists and then resolve it
5943 (using WHOIS) if it cannot be found. Affected file is
5946 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5948 * Implemented the BAN command to the client library.
5950 * The JOIN command in the server now checks the invite list
5953 * Changed the silc_command_reply_payload_encode_va and the
5954 silc_command_payload_encode_va to support that if argument is
5955 NULL it ignores and checks the next argument. Affected file
5956 lib/silccore/silccommand.c.
5958 * Added silc_server_send_notify_ban to send the BAN notify
5959 type between routers.
5961 * Chaned the silc_notify_payload_encode to support that if
5962 argument is NULL it ignores and checks the next argument.
5963 Affected file lib/silccore/silcnotify.c.
5965 * Tested ban lists in router environment successfully.
5967 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5969 * Implemented BAN command to the server, in silcd/command.[ch].
5971 * Removed the BAN and INVITE_LIST modes from the CMODE command
5974 * Added function silc_string_match to regex match two strings.
5975 Affected files lib/silcutil/silcutil.[ch].
5977 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5979 * Redefined parts of the SilcChannelEntry in the server to support
5980 the new ban and invite lists.
5982 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5984 * Redefined the INVITE command. The same command can be used to
5985 invite individuals to the channel but also to manage the invite
5986 list of the channel (to add to and remove from the invite list).
5987 Updated the protocol specs.
5989 * Added new command SILC_COMMAND_BAN that can be used to manage
5990 the ban list of the channel. Updated the protocol specs.
5992 * Removed the channel modes: the SILC_CMODE_BAN and the
5993 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5994 in the CMODE command. The equivalent features are now available
5995 using INVITE and BAN commands. Updated the protocol specs.
5997 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5998 in the network about change in the current ban list. The notify
5999 type is not used by the client.
6001 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
6002 support the invite lists.
6004 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6006 * Added new function silc_string_regexify that converts string
6007 including wildcard characters into regex string that can
6008 be used by the GNU regex library. Added into the file
6009 lib/silcutil/silcutil.[ch].
6011 Added silc_string_regex_combine to combine to regex strings
6012 into one so that they can be used as one regex string by
6013 the GNU regex library. Added into the file
6014 lib/silcutil/silcutil.[ch].
6016 Added silc_string_regex_match to match two strings. It returns
6017 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
6019 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6021 * Imported GNU regex to the soruce tree into lib/contrib.
6022 Fixed some compiler warning from the regex.c.
6024 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6026 * Fixed MOTD command in the server to work in router environment.
6028 * Fixed the MOTD command in the client library to support
6029 the server argument in the command.
6031 * Added `nickname_len' argument to the silc_idlist_add_client
6032 in the server, as the `nickname' argument may be binary data
6035 * Added silc_idlist_get_channels to return all channels from
6038 * Implemented LIST command to the server. Affected file is
6041 * Implemented the LIST command to the client library and on the
6044 * Added [<user count>] argument to the LIST command reply.
6045 With private channels the user count is not shown.
6047 * Updated TODO and README.
6049 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6051 * The client entry's data.registered must be TRUE even with
6052 global client entry on global client list. The data.registered
6053 is used to check whether the client is anymore in the network,
6054 for example with WHOWAS command so it must be valid.
6056 * Fixed the WHOWAS command in the server. It now actually works
6057 in router environment. Added function into silcd/command_reply.c
6058 silc_server_command_reply_whowas_save.
6060 * Added silc_idlist_purge function to the silcd/idlist.c
6061 to periodically purge the ID Cache.
6063 * Fixed INFO command in the server. It works now in router
6064 environment. Added <server name> argument to the INFO command
6065 reply. Updated the protocol specs.
6067 * Fixed minor bug in silc_idcache_purge to not purge if the
6068 expire value is zero.
6070 * Fixed various bugs in WHOIS and IDENTIFY command handling as
6071 they were buggy because of the WHOWAS information.
6073 * Fixed local command MSG to handle the async resolving of
6074 the remote client properly. It used to fail the first MSG.
6075 Affected file silc/local_command.c.
6077 * Added `data_len' field to SilcIDCache context.
6079 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6081 * Update TODO. Todo in commands in the server.
6083 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6085 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
6086 used by routers as broadcast packet to inform other routers
6087 about the changed user mode.
6089 Implemented the notify handling in the server. Affected file is
6090 silcd/packet_receive.c. Added the function
6091 silc_server_send_notify_umode to the silcd/packet_send.[ch].
6093 * Added new generic Channel Payload and deprecated the New Channel
6094 Payload. The New Channel Payload is now the generic Channel
6097 * Added new argument `mode' to the silc_server_send_new_channel
6098 as it is required in the Channel Payload now.
6100 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
6101 and created a new and real SilChannelPayload to represent the
6102 new generic Channel Payload. Implemented the encode/decode
6103 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
6105 * Added silc_server_get_client_channel_list to return the list
6106 of channels the client has joined for WHOIS command reply.
6107 Affected file silcd/server.[ch].
6109 * Implemented the channel list sending in the WHOIS command reply
6110 in server and in the client.
6112 Implemented the channel list displaying on the user interface
6113 as well. Affected file silc/client_ops.c.
6115 * Added silc_channel_payload_parse_list to parse list of Channel
6116 Payloads. It returns SilcDList list of SilcChannelPayloads.
6117 Client for example can use this function to parse the list of
6118 channels it receives in the WHOIS command reply. The caller
6119 must free the list by calling silc_channel_payload_list_free.
6120 Affected files lib/silccore/silcchannel.[ch].
6122 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6124 * Added one new argument <user mode> to the WHOIS command reply
6125 to return the mode of the user in SILC. Updated the protocol
6128 Implemented it to the server and client.
6130 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6132 * Fixed the mode printing on the user interface on joining.
6133 Affected file silc/client_ops.c.
6135 * Implemented the UMODE command and user modes in general to the
6136 client library and to the user interface.
6138 * Implemented the UMODE command to the server.
6140 * The server now sends UNKNOWN_COMMAND error status if client sends
6141 unknown command. Affected file silcd/command.c.
6143 * All server commands now handle the command identifier the right
6144 way when sending the command reply to the client. The client can
6145 use to identify the command replies with the identifier.
6147 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6149 * Added silc_server_get_client_route to resolve the route to
6150 the client indicated by the client ID. Affected file is
6153 * Added silc_server_relay_packet as general function to relay
6154 packet to arbitrary destination. This deprecates functions
6155 like _send_private_message_key, _relay_notify etc. Affected
6156 file is silcd/packet_send.[ch].
6158 Removed silc_server_send_key_agreement,
6159 silc_server_send_private_message_key and
6160 silc_server_packet_relay_notify functions from the file
6161 silcd/packet_send.[ch].
6165 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
6166 server. Affected file silcd/packet_receive.[ch].
6168 * Implemented the KILL command to the client. Implemented the
6169 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
6170 Affected files lib/silcclient/command[_reply].c and
6171 lib/silcclient/client_notify.c. Implemented the KILL notify
6172 printing in the user inteface.
6174 * Fixed a lot silc_parse_nick memory leaks from the client
6175 library in the file lib/silcclient/command.c.
6177 * Changed the silc_server_send_notify_on_channels's `sender'
6178 argument from SilcSocketConnection to SilcClientEntry to
6179 check the sender as entry and not as connection object and not
6180 to send to the client provided as argument. The affected file
6181 is silcd/packet_send.[ch].
6183 * The notify packets that are destined directly to the client used
6184 to not to be processed by the server. Now changed that and the
6185 server processes all notify packets. After relaying the packet
6186 to the client the notify packet is processed in the server.
6188 * The silc_server_free_client_data now checks whether there is
6189 pending outgoing traffic for the client and purges the data to
6190 the network before removing the client entry.
6192 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6194 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
6195 an client is killed from the SILC Network. Updated the protocol
6198 Added new function silc_server_send_notify_killed to the
6199 silcd/packet_send.[ch].
6201 * Added function silc_server_packet_relay_notify to relay notify
6202 packets that are destined directly to a client. In this case
6203 the server does not process the notify packets but merely relays
6204 it to the client. Affected file silcd/packet_send.[ch].
6206 Added also silc_server_packet_process_relay_notify to check
6207 whereto relay the notify. Affected file is
6208 silcd/packet_receive.[ch].
6210 * Implemented the KILL command to the server.
6214 * Added the backup schema desgined last fall to the protocol
6215 specs for everyone to see. The specification is in the
6216 *-spec-xx.txt draft and the packet type definitions for the
6217 backup routers is in *-pp-xx.txt draft. Thusly, added also
6218 new packet type SILC_PACKET_CELL_ROUTERS.
6220 * A big security problem in the implementation discovered. The
6221 signoff of an client did not cause new channel key generation
6222 which it of course should've done. The channel keys must be
6223 always re-generated when client leaves (or signoffs) the channel.
6224 The silc_server_remove_from_channels funtion now handles
6225 the channel key re-generation.
6227 * Added `sender' argument to the silc_server_send_notify_on_channels
6228 to not to send the client provided as argument. Affected file
6229 silcd/packet_send.[ch].
6231 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6233 * Implemented OPER and SILCOPER commands into the server and
6236 * Added silc_auth_verify and silc_auth_verify_data to verify
6237 the authentication directly from the authentication payload.
6238 It supports verifying both passphrase and public key based
6239 authentication. Affected file lib/silccore/silcauth.[ch].
6241 * Added `hash' field to the SilcIDListData structure. It is the
6242 hash negotiated in the SKE protocol. Affected file is
6245 * Slight redesigning of the SilcAuthPayload handling routines.
6246 Do not send SilcPKCS but SilcPublicKey as argument.
6248 * Implemented the public key authentication support to the
6249 serverconfig. The public key is loaded from the provided path
6250 and saved as authentication data to void * pointer. Thus,
6251 changed the unsigned char *auth_data to void *auth_data;
6253 * Fixed SHUTDOWN command to send the reply before the server
6254 is shutdown. :) Affected file silcd/command.c.
6256 * Fixed fatal bug in CONNECT command. The hostname was invalid
6257 memory and server crashed. Affected file silcd/command.c.
6259 * Fixed fatal bug in CLOSE command. The server_entry became
6260 invalid but was referenced later in the command. Affected file
6263 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6265 * Fixed fatal bug in failure packet handling. Server ignored
6266 the failure and thus crashed when it came.
6270 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6272 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
6273 that the command may be executed only once in (about) 2 seconds.
6274 The old SILC_CF_LAG flag is same but allows command bursts up
6275 to five before limiting.
6277 Added the support for CF_LAG and CF_LAG_STRICT flags to the
6278 server code. Various commands now includes the CF_LAG_STRICT
6279 flag to disallow any kind of miss-use of the command.
6281 * Fixed the silc_buffer_unformat to not to allocate any data
6282 if the length of the data is zero. It used to allocate the
6283 length + 1. Affected file lib/silcutil/silcbuffmt.c.
6285 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6287 * Changed the format of AdminConnection configuration section
6288 in the server. Added username of the admin to the format.
6289 Affected files silcd/serverconfig.[ch].
6291 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
6292 to return admin configuration data by host, username and/or
6295 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6297 * Implemented WHOWAS command to the server. Added the functions:
6299 silc_server_command_whowas_parse,
6300 silc_server_command_whowas_send_reply,
6301 silc_server_command_whowas_from_client and
6302 silc_server_command_whowas_from_server
6304 * Added <Client ID> argument to the WHOWAS command reply. Updated
6305 the protocol specs accordingly.
6307 * Implemented WHOWAS command and command_reply to the client
6310 Implemented the WHOWAS printing on the user interface.
6312 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6314 * Added new argument to the WHOWAS command reply, the real name.
6315 It is an optional argument. Updated the protocol specs.
6317 * Added SilcIDCacheDestructor callback that is registered when
6318 the SilcIDCache is allocated. The callback is called when
6319 an cache entry in the ID Cache expires, or is purged from the
6320 cache. Added into lib/silccore/idcache.[ch].
6322 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
6323 to destruct the client entries when the cache entry expires.
6324 Other ID Cache's in server and in the client library ignores
6327 * If the ID Cache entry's `expire' field is zero then the entry
6328 never expires. Added boolean `expire' argument to the
6329 silc_idcache_add function in the lib/silccore/idcache.[ch].
6330 If it is TRUE the default expiry value is used.
6332 * Added silc_server_free_client_data_timeout that is registered
6333 when client disconnects. By default for 5 minutes we preserve
6334 the client entry for history - for WHOWAS command.
6336 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6338 * Added support to the server to enforce that commands are not
6339 executed more than once in 2 seconds. If server receives
6340 commands from client more frequently, timeout is registered
6341 to process the commands. Affected file silcd/command.c.
6342 Added new function silc_server_command_process_timeout.
6344 * Changed NICK_NOTIFY handling in client library to check that
6345 if the client's nickname was changed, so there is no need to
6346 resolve anything from the server.
6348 * Removed error printing from the WHOIS and IDENTIFY commands.
6349 If error occurs then it is ignored silently in the client library.
6350 The application, however, may map the received error to
6351 human readable error string. The application currently maps
6352 the NO_SUCH_NICKNAME error to string.
6354 * Made the command status message public to the application. Moved
6355 them from lib/silcclient/command_reply.c to
6356 lib/silcclient/command_reply.h. The application can map the
6357 received command status to the string with the
6358 silc_client_command_status_message function.
6360 * Added check to the server to check that client's ID is same
6361 as the Source ID in the packet the client sent. They must
6364 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6366 * Added dist-bzip hook to the Makefile.am to make bzip2
6367 compressed distributions.
6369 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6371 * Server now enforces the maximum length for the nickname and
6372 the channel as protocol specification dictates. 128 bytes for
6373 nickname and 256 bytes for channel name.
6375 * Moved the WHOIS printing to the application. The client libary
6376 does not print out the WHOIS information anymore, the application
6377 must do it. Renamed silc_client_command_reply_whois_print to
6378 the silc_client_command_reply_whois_save.
6380 The client's idle time is also sent to the application now, and
6381 the idle is shown on screen.
6383 * Added silc_client_command_reply_identify_save to save the
6384 received IDENTIFY entries.
6386 * Do not check for channel private keys in message sending and
6387 reception if the channel does not have the PRIVKEY mode set.
6388 Affected file lib/silclient/client_channel.c.
6390 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6392 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
6393 just surfaced after chaning the JOIN procedure.
6395 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6397 * Added silc_client_get_clients_by_list to get client entries
6398 from Client ID list, that is returned for example by JOIN
6399 and USERS command replies. The application should use this
6400 function for example when JOIN command reply is received to
6401 resolve the clients already on the channel (library does not
6402 do that anymore as USERS command reply is not used in the JOIN
6403 procedure anymore). Affected files lib/silcclient/silcapi.h and
6404 lib/silcclient/idlist.c.
6406 * JOIN command reply and USERS command reply returns now SilcBuffer
6407 pointers instead of unsigned char pointers when returning
6408 the client list and mode list.
6410 * Added <Client ID> argument to the JOIN command reply, mainly
6411 for the server to identify for which client the command was
6412 originally sent. Updated protocol specs accordingly.
6414 * Added SilcDlist private_key pointer to the SilcChannelEntry
6415 in the client to support the channel private keys. Affected
6416 file is lib/silcclient/idlist.h.
6418 * Added SilcChannelPrivateKey argument to the function
6419 silc_client_send_channel_message so that application can choose
6420 to use specific private ke if it wants to. If it is not provided,
6421 the normal channel key is used, unless private keys are set.
6422 In this case the first (key that was added first) is used
6423 as the encryption key.
6425 * Implemented the support for channel private key handling.
6426 Implemented the following functions:
6428 silc_client_add_channel_private_key,
6429 silc_client_del_channel_private_keys,
6430 silc_client_del_channel_private_key,
6431 silc_client_list_channel_private_keys and
6432 silc_client_free_channel_private_keys
6434 Affected file lib/silcclient/client_channel.c.
6436 * Added the support for the private keys in the channel message
6437 sending and encryption and in the message reception and
6438 decryption. Affected funtions are
6439 silc_client_send_channel_message and silc_client_channel_message.
6441 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6443 * Added SKE's key verify callback to the client library's
6444 KE protocol context. Affected files lib/silcclient/protocol.[ch].
6446 * Removed the statement that server (or router) must send USERS
6447 command reply when joining to the channel so that the client
6448 knows who are on the channel. Instead, the client list and
6449 client's mode list is now sent in the JOIN command reply to the
6450 client who joined channel. This is better solution.
6452 * Added function silc_server_get_users_on_channel and function
6453 silc_server_save_users_on_channel to the silcd/server.[ch].
6455 * Removed function silc_server_command_send_users from the
6458 * Do not show topic on the client library anymore. The topic is
6459 sent in the command reply notify to the application and the
6460 application must show the topic now.
6462 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6464 * Added client searching by nickname hash into the IDENTIFY and
6465 WHOIS commands in the server as they were clearly missing from
6466 them. Affected file is silcd/command.c.
6468 * Fixed a bug in private message receiving in the client library.
6469 The remote ID was freed and it wasn't supposed, now it is
6472 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6474 * Minor fix to the channel payload; allocate the data area, as it
6475 needs to be of specific length.
6477 * If the key agreement port is zero then the operating
6478 system will define the bound port. Affected files are
6479 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
6481 * Added new function silc_channel_payload_decrypt into the file
6482 lib/silccore/silcchannel.[ch].
6484 * Moved the channel message etc, check from silc_packet_decrypt
6485 to applications. The library calls now a generic
6486 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
6487 when the packet is either normal or special. This was done to
6488 allow more wide range of checking that was not allowed when
6489 the code was in library. Now applications can do virtually any
6490 checks to the packet and return to the library the decision how
6491 the packet should be processed. Affected files are
6492 lib/silccore/silcpacket.[ch].
6494 Added silc_server_packet_decrypt_check to the server and
6495 silc_client_packet_decrypt_check to the client library.
6497 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
6498 to send with specified source and destination information.
6500 * Channel message delivery between routers was broken after the
6501 channel key distribution was fixed earlier. The channel key
6502 was used be to distributed to other routers as well which is not
6503 allowed by the protocol. Now this is fixed and channel keys
6504 really are cell specific and the channel message delivery between
6505 routers comply with the protocol specification.
6507 * Fixed various commands in server to check also the global list
6508 for the channel entry and not just the local list. The affected
6509 file silcd/command.c.
6511 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6513 * Added assert()s to buffer formatting and unformatting routines
6514 to assert (if --enable-debug) when error occurs. Affected
6515 file: lib/silcutil/silcbuffmt.c.
6517 * Changed to auto-reconnect to check whether the remote host is
6518 router and register the re-connect timeout if it is. It used
6519 to check that whether we are normal server, but router must do
6520 auto-reconnect with another router as well. Affected file
6523 * Removed the [<key len>] option from CMODE command as the cipher
6524 name decides the key length, nowadays. See the defined ciphers
6525 from the protocol specification.
6527 * Added [<hmac>] option to the CMODE command to define the HMAC
6528 for the channel. Added SILC_CMODE_HMAC channel mode.
6530 * Added [<hmac>] option for the JOIN command so that user can
6531 select which HMAC is used to compute the MACs of the channel
6534 * Added Hmac field to the Channel Message Payload. The integrity
6535 of plaintext channel messages are now protected by computing
6536 MAC of the message and attaching the MAC to the payload. The
6537 MAC is encrypted. Now, it is clear that this causes some
6538 overhead to the size of the packet but rationale for this is that
6539 now the receiver can verify whether the channel message decrypted
6540 correctly and also when private keys are set for the channel the
6541 receiver can decrypt the packet with several keys and check from
6542 the MAC which key decrypted the message correctly.
6544 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
6545 lib/silccrypt/silccipher.[ch].
6547 * Added silc_hash_len to return the digest length into the
6548 lib/silcrypt/silchash.[ch].
6550 * Rewrote parts of Silc Channel Payload interface in the
6551 lib/silccore/silcchannel.[ch]. The encode function now also
6552 encrypts the packet and parse function decrypts it.
6554 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6556 * Fixed a minor formatting bug in the SKE's key material processing.
6557 It actually might have processed the keys wrong way resulting
6560 * Redefined the mandatory HMAC algorithms and added new algorithms.
6561 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
6562 and hmac-md5 truncated to 96 bits. The mandatory is now
6563 hmac-sha1-96. Rest are optional (including the one that used
6564 to be mandatory). Rationale for this is that the truncated HMAC
6565 length is sufficient from security point of view and can actually
6566 make the attack against the HMAC harder. Also, the truncated
6567 HMAC causes less overhead to the packets. See the RFC2104 for
6570 * Added new [hmac] configuration section. The SKE used to use
6571 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
6572 is of course wrong. The official names that must be proposed in
6573 the SKE are the ones defined in the protocol specification
6574 (hmac-sha1-96 for example). The user can configure any hmac
6575 using any hash function configured in the [hash] section. At
6576 least, the mandatory must be configured.
6578 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
6580 * Added HMAC list to the SKE proposal list. It has now both
6581 hash algorithm list and HMAC list. This makes the protocol
6582 incompatible with previous versions. The SKE now seems to work
6583 the way it is supposed to work, for the first time actually.
6585 * Defined plain Hash algorithms to the protocol specification.
6588 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6590 * Implemented support for key agreement packets into the server.
6591 Added functions silc_server_key_agreement and
6592 silc_server_send_key_agreement. Other than these functions,
6593 server has nothing to do with this packet.
6595 * Added support for private message key packets into the server.
6596 Added functions silc_server_private_message_key and
6597 silc_server_send_private_message_key.
6601 * Changed the silc_[client|server]_protocol_ke_set_keys to be
6602 called in the protocol's final callback instead in the END
6603 protocol state. This makes a little more sense and in the same
6604 time in client we can use the same protocol routines for normal
6605 key exchange and to key agreement packet handling as well.
6607 * Added to both client's and server's KE protocol context the
6608 SilcSKEKeyMaterial pointer to save the key material. We will
6609 bring the key material to the protocol's final callback by doing
6610 this. The final callback must free the key material.
6612 * Added SKE's packet_send callback into client's KE protocol
6613 context so that the caller can choose what packet sending function
6614 is used. This way we can use different packet sending when
6615 doing normal SKE when doing key agreement packet handling (in
6616 the key agreement packet handling we do not want to encrypt
6619 * Implemented the responder side of the key agreement routines
6620 in the client. The client can now bind to specified port and
6621 accept incoming key negotiation. The key material is passed
6622 to the application after the protocol is over.
6624 * Implemented the processing of incoming Key Agreement packet
6625 in the client. Added function silc_client_key_agreement to
6628 * Implemented the intiator side of the key agreement routines
6629 in the client. The client can now initiate key agreement with
6630 another remote client. The key material is passed to the
6631 application after the protocol is over.
6633 * Created client_keyagr.c to include all the key agreement
6636 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
6637 SILC_TASK_CALLBACK except that it is not static.
6639 * Created client_notify.c and moved the Notify packet handling
6640 from the client.[ch] into that file.
6642 * Created client_prvmsg.c and moved all private message and
6643 private message key routines from the client.[ch] into that file.
6645 * Create client_channel.c and moved all channel message and
6646 channel private key routines from the client.[ch] into that file.
6648 * Changed silc_client_get_client_by_id_resolve to resolve with
6649 WHOIS command instead of IDENTIFY command, in the file
6650 lib/silclient/idlist.c.
6652 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6654 * Implemented the SKE's responder side to the Client library.
6656 * When FAILURE is received to the protocol do not trust it
6657 blindly. Register a timeout to wait whether the remote closes
6658 the connection as it should do it, only after that process the
6659 actual failure. This was changed to both client and server.
6661 * Added client_internal.h to include some of the structures
6662 there instead of client.h in lib/silcclient/.
6664 * Added function silc_task_unregister_by_callback to unregister
6665 timeouts by the callback function.
6667 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6669 * Some "Incomplete WHOIS info" errors has been appearing on the
6670 log files. Took away the entry->userinfo check from WHOIS
6671 reply sending. The entry->userinfo is now " " if client did not
6672 provide one. I thought this was fixed earlier but something
6673 is wrong still. Let's see if the error still appears.
6675 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6677 * Fixed a minor bug in the login when the channel key is
6678 re-generated in the server. It used to generate the key in
6679 wrong order and thus caused problems in the channel traffic.
6681 * Fixed a minor bug in channel key distsribution after
6682 KICK command. The key was not sent to the router even though
6685 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6687 * Added silc_ske_process_key_material_data as generic routine
6688 to process any key material as the SILC protocol dictates. The
6689 function is used by the actual SKE library but can be used by
6690 applications as well. This relates to the private message keys
6691 and the channel private keys since they must be processed the
6692 same way the normal SILC session keys. The protocol dictates
6693 this. Affected files: lib/silcske/silcske.[ch].
6695 Added also silc_ske_free_key_material to free the
6696 SilcSKEKeyMaterial structure.
6698 * Defined silc_cipher_set_key function to set the key for
6699 cipher without using the object's method function. The affected
6700 files: lib/silccrypt/silccipher.[ch].
6702 * Implemented silc silc_client_add_private_message_key,
6703 silc_client_add_private_message_key_ske,
6704 silc_client_del_private_message_key,
6705 silc_client_list_private_message_keys and
6706 silc_client_free_private_message_keys functions in the
6709 Added functions silc_client_send_private_message_key to send
6710 the Private Message Key payload and silc_client_private_message_key
6711 to handle incoming Private Message Key payload.
6713 * Added Cipher field to the Private Message Key payload to set
6714 the cipher to be used. If ignored, the default cipher defined
6715 in the SILC protocol (aes-256-cbc) is used.
6717 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6719 * Removed lib/silcclient/ops.h file.
6721 Redefined parts of the SILC Client Library API. Created new
6722 file silcapi.h that deprecates the ops.h file and defines the
6723 published Client Library API. Defined also private message key
6724 API and channel private key API into the file.
6726 This is the file that the application must include from the
6727 SILC Client Library. Other files need not be included by
6728 the application anymore.
6730 * Added new key_agreement client operation callback and also
6731 defined the Key Agreement library API for the application.
6733 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6735 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
6736 is used by clients to request key negotiation between another
6737 client in the SILC network. If the negotiation is started it
6738 is performed using the SKE protocol. The result of the
6739 negotiation, the secret key material, can be used for example
6740 as private message key.
6742 Implemented the Key Agreement payload into the files
6743 lib/silccore/silauth.[ch].
6745 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6747 * Redefined ciphers for the SILC protocol. Added some new ciphers
6748 and defined the key lengths for the algorithms. Changed the
6749 code accordingly. The default key length is now 256 bits.
6751 * Fixed SKE key distribution function silc_ske_process_key_material
6752 when the key length is more than 128 bits. The default key
6753 length in SILC is now 256 bits.
6755 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
6756 to indicate unsupported algorithm.
6758 * Renamed rijndael.c to aes.c and all functions as well.
6760 * Fixed a long standing channel key setting bug in client library.
6761 Weird that it has never surfaced before.
6763 * Fixed bug in channel deletion. If the entire channel is removed
6764 then it must also delete the references of the channel entry
6765 from the client's channel list as the client's channel entry and
6766 the channel's client entry share same memory.
6768 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6770 * Implemented CONNECT and SHUTDOWN commands in the client.
6772 * Implemented CLOSE command to the client.
6774 * Added the function silc_idlist_find_server_by_name into the
6775 files silcd/idlist.[ch].
6777 Added the function silc_idlist_find_server_by_conn into the
6778 files silcd/idlist.[ch].
6780 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6782 * DIE command was renamed to SHUTDOWN. Updated the both code
6785 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
6786 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
6788 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
6791 * Added function silc_server_create_connection function to create
6792 connection to remote router. My server implementation actually
6793 does not allow router to connect to normal server (it expects
6794 that normal server always initiates the connection to the router)
6795 so the CONNECT command is only good for connecting to another
6798 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6800 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
6801 or some other client was kicked from the channel.
6803 Implemented the handling of the notify type to both client
6806 Implemented silc_server_send_notify_kicked to send the KICKED
6807 notify. It is used to send it to the server's primary router.
6809 * Implemented the KICK command into server and client.
6811 * Added `query' argument to the silc_idlist_get_client function
6812 to indicate whether to query the client from server or not if
6815 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
6816 to indicate that the client is not channel founder.
6820 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6822 * Removed the rng context from SilcPacketContext structure and
6823 changed that the packet routine uses the Global RNG API.
6825 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6827 * Added support for quit message that client can "leave" on the
6828 channel when it quits the SILC. It is ditributed inside the
6829 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6831 Added silc_server_free_client_data that will take the
6832 signoff message as argument.
6834 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6836 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6838 * Updated parts of the protocol specification to keep it up
6841 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6843 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6844 payloads in one packet.
6846 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6847 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6848 use now the new List flag.
6850 * Also deprecated the following packet types: REPLACE_ID,
6851 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6853 * Added list support for Notify packet in server.
6855 * Added silc_server_send_notify_channel_change to send the
6856 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6857 the silc_server_send_replace_id.
6859 * Added silc_server_send_notify_nick_change to send the
6860 NICK_CHANGE notify type. Deprecates the function
6861 silc_server_send_replace_id.
6863 * Added silc_server_send_notify_join to send the JOIN notify type.
6864 Deprecates the function silc_server_send_new_channel_user.
6866 * Added silc_server_send_notify_leave to send LEAVE notify type.
6867 Deprecates the function silc_server_send_remove_channel_user.
6869 * Added silc_server_send_notify_cmode and
6870 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6871 types. Deprecates the silc_server_send_set_mode function.
6873 * Added SERVER_SIGNOFF notify type to indicate that server has
6874 quit. This means that all clients on the channel from that
6875 server will drop. This can be also used when netsplit happens.
6877 Deprecated REMOVE_ID packet type since it is not needed anymore
6880 Added silc_server_send_notify_server_signoff to send the
6881 SERVER_SIGNOFF notify type. Deprecates the function
6882 silc_server_send_remove_id.
6884 Added also silc_server_send_notify_signoff to send the
6885 SIGNOFF notify type.
6887 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6888 SILC protocol from this day on. Changed the protocol
6889 specification as well.
6891 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6892 notify type. It is used between routers to notify about
6893 topic changes on a channel.
6895 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6898 * Partly updated the protocol specification to comply with the
6899 changes now made. It is still though a bit outdated.
6901 * The JOIN notify type now takes one extra argument <Channel ID>.
6902 The packet used to be destined to the channel but now the
6903 JOIN type may be sent as list thus it is impossible to
6904 destine it to any specific channel. By adding this argument
6905 it is again possible.
6907 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6909 * Added CREDITS file. The CHANGES and CREDITS file will appear
6910 in the distribution as well.
6912 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6914 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6915 types in the server's silcd/packet_receive.c.
6917 * Implemented CMODE and CUMODE to work in router environment.
6919 * Fixed minor encoding and decoding buglet from the
6920 lib/silccore/silcmode.c.
6922 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6925 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6927 * Changed all SilcConfigServer* and silc_config_server* to
6928 SilcServerConfig* and silc_server_config*, respectively.
6931 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6933 * Associated the ID (client or server ID) to the Authentication
6934 Payload to avoid any possibility of forging. Updated the
6935 protocol specification and the code accordingly.
6937 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6939 * The RSA key length is now save to the RsaKey context in the
6940 key generation process in lib/silccrypt/rsa.c. The key length
6941 is now used to figure out the maximum size of the block allowed
6942 to be encrypted/signed.
6944 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6945 is equivalent to the silc_mp_mp2bin but does not allocate any
6948 * Changed silc_mp_mp2bin API to take length argument. If it is
6949 non-zero then the buffer is allocated that large. If zero, then
6950 the size is approximated using silc_mp_sizeinbase, which however
6953 * Created Global RNG API which is global RNG that application can
6954 initialize. After initializing, any routine anywhere in the
6955 code (including library) can use RNG without allocating a new
6956 RNG object. This was done to allow this sort of use of the
6957 RNG in code that has no chance to allocate RNG object. All
6958 applications currently allocate this and many routines in the
6959 library use this. Affected file lib/silccrypt/silcrng.[ch].
6961 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6962 it to use the Global RNG API.
6964 * Defined Authentication Payload into protocol specification that
6965 is used during SILC session to authenticate entities. It is
6966 used for example by client to authenticate itself to the server
6967 to obtain server operator privileges.
6969 Implemented this payload into the lib/silccore/silcauth.[ch].
6970 Implemented also routines for public key based authentication
6971 as the new protocol specification dictates.
6973 Moved definitions of different authentication methods from
6974 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6976 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6977 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6978 silc_pkcs_verify_with_hash functions into the file
6979 lib/silccrypt/silcpkcs.[ch].
6981 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6983 * The client entry's userinfo pointer must be always valid.
6984 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6985 will fail since it requires the userinfo. Now, the userinfo
6986 is allocated as "" if actual userinfo does not exist. Actually,
6987 it must exist and it is totally Ok to drop client connections
6988 that does not announce the userinfo. However, we will make
6989 this workaround for now.
6991 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6992 to return the remote port by socket.
6994 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6996 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6997 SILC_SERVER_PENDING_EXEC and added an new macro
6998 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6999 data or when error occurs while processing the pending command.
7001 Added new argument `destructor' into silc_server_command_pending
7002 and to the SilcServerCommandPending object. This destructor is
7003 now called after calling the pending callback or if error occurs
7004 immediately. If error occurs the actual pending callback won't
7005 be called at all - only the destructor. The destructor may be
7006 NULL if destructor is not needed.
7008 All this applies for client library code as well. Similar
7009 changes were made there as well for the pending commands.
7011 In the client, the application must now allocate the
7012 SilcClientCommandContext with the silc_client_command_alloc
7015 * Added reference counter to the SilcServerCommandContext. Added
7016 function silc_server_command_alloc and silc_server_command_dup
7019 Same type of functions added to the client library for the same
7022 * Removed the cmd_ident from IDListData away since it is now
7023 global for all connections. It is the command identifier used
7024 in command sending and with pending commands. The affected file
7027 * Added reference counter to the SilcSocketConnection objecet to
7028 indicate the usage count of the object. The object won't be
7029 freed untill the reference counter hits zero. Currently only
7030 server uses this, and client ignores it. The client must be
7031 set to use this too later. The affected files are
7032 lib/silccore/silcsockconn.[ch]. Added also the function
7033 silc_socket_dup to increase the reference counter.
7035 This was mainly added because it is possible that the socket
7036 is removed underneath of pending command or other async
7037 operation. Now it won't be free'd and proper DISCONNECTING
7038 flags, etc. can be set to avoid sending data to connection that
7039 is not valid anymore.
7041 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
7042 the connection. After that it sets SILC_SET_DISCONNECTED.
7043 It is, however, possible that the socket data is not still freed.
7044 The silc_server_packet_process now checks that data is not
7045 read or written to connection that is DISCONNECTED. The socket
7046 get's freed when the reference counter hits zero.
7048 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7050 * Changed the client operation API: channel_message operation's
7051 `sender' is now the client entry of the sender, not the nickname
7052 and the `channel' is the channel entry, not the channel name.
7054 In the private_message operation the `sender' is now also the
7055 client entry of the sender not the nickname.
7057 Affected file is lib/silcclient/ops.h and all applications
7058 using the client operations.
7060 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7062 * Moved the calling of ops->connect() from connect_to_server_final
7063 into receive_new_id functin since that is the point when the
7064 client is actually allowed to send traffic to network. The
7065 affected file is lib/silcclient/client.c.
7067 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7069 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
7070 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
7071 (if needs broadcasting) instead of broadcasting the packets one
7072 by one which would make a burst in the network traffic.
7074 * Added `broadcast' argument to the functions in silcd/server.[ch]
7075 silc_server_create_new_channel[_with_id] to indicate whether
7076 to send New Channel packet to primary router.
7078 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7080 * Added new function into the silcd/server.[ch] files:
7081 silc_server_create_new_channel_with_id to create new channel with
7082 already existing Channel ID.
7084 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
7085 lib/silccore/silcpacket.h. This packet is used t send list of
7086 Set Mode payloads inside one packet. Server uses this to set
7087 the modes for the channels and clients on those channels, that it
7088 announced to the router when it connected to it. The protocol
7089 specification has been updated accordingly.
7091 * The silc_server_new_channel did not handle the packet coming
7092 from normal server as it normally does not send that. However,
7093 when it announces its channels it does send it. Implemented
7094 the support for that.
7096 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
7097 into the file lib/silccore/id.h.
7099 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7101 * Fixed memory leaks in the functions silc_idlist_del_client,
7102 silc_idlist_del_channel and silc_idlist_del_server in the file
7103 silcd/idlist.c. All of those leaked like a sieve.
7105 * Fixed some small memory leaks in the client's function
7106 silc_client_notify_by_server.
7108 * Added functions into silcd/server.c: silc_server_announce_clients,
7109 silc_server_announce_channels and silc_server_announce_server.
7110 These functions are used by normal and router server to announce
7111 to its primary router about clients, channels and servers (when
7112 router) that we own. This is done after we've connected to the
7115 These functions effectively implements the following packet types:
7116 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
7117 and SILC_PACKET_NEW_ID_LIST.
7119 * Added new functions into the silcd/packet_receive.[ch]:
7120 silc_server_new_id_list, silc_server_new_channel_list and
7121 silc_server_new_channel_user_list to handle the incoming
7122 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
7124 * Added support of changing Channel ID in the function
7125 silc_server_replace_id. If the server that announces a channel
7126 to the router already exists in the router (with same name but
7127 with different Channel ID), router is responsible to send
7128 Replace ID packet to the server and force the server to change
7129 the Channel ID to the one router has.
7131 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
7132 client that the Channel ID has been changed by the router. The
7133 normal server sends this to the client. Client must start using
7134 the new Channel ID as the channel's ID.
7136 Implemented handling of this new type into lib/silcclient/client.c
7137 into the function silc_client_notify_by_server.
7139 * Added new function silc_idlist_replace_channel_id into the files
7140 silcd/idlist.[ch] to replace the Channel ID.
7142 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7144 * Call silc_server_command_identify_check always when processing
7145 the IDENTIFY command in silcd/command.c
7147 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7149 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
7150 send keepalive packets. The packet can be sent by clients,
7151 servers and routers.
7153 Added function silc_socket_set_heartbeat into the file
7154 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
7155 If not set, the heartbeat is not performed. The actual
7156 heartbeat is implemented in the low level socket connection
7157 library. However, application is responsible of actually
7160 Added silc_server_send_heartbeat to send the actual heartbeat
7161 packet into silcd/packet_send.[ch]. Server now performs
7162 keepalive with all connections.
7164 * Added silc_task_get_first function into lib/silcutil/silctask.c
7165 to return the timeout task with shortest timeout. There was a bug
7166 in task unregistration that caused problems. TODO has been
7167 updated to include that task system must be rewritten.
7169 * The client library will now resolve the client information when
7170 receiving JOIN notify from server for client that we know but
7171 have incomplete information.
7173 * Rewrote parts of silc_server_remove_from_channels and
7174 silc_server_remove_from_one_channel as they did not remove the
7175 channel in some circumstances even though they should've.
7177 * Encryption problem encountered in server:
7179 The LEAVE command used to send the Channel Key packet to the
7180 router immediately after generating it. However, the code
7181 had earlier sent Remove Channel user packet but not immediately,
7182 ie. it was put to queue. The order of packets in the router
7183 was that Channel Key packet was first and Remove Channel User
7184 packet was second, even though they were encrypted in the
7185 reverse order. For this reason, MAC check failed. Now, this
7186 is fixed by not sending the Channel Key packet immediately but
7187 putting it to queue. However, this is more fundamental problem:
7188 packets that are in queue should actually not be encrypted
7189 because packets that are sent immediately gets encrypted
7190 actually with wrong IV (and thus MAC check fails). So, packets
7191 that are in queue should be encrypted when they are sent to
7192 the wire and not when they put to the queue.
7194 However, the problem is that the current system has not been
7195 designed to work that way. Instead, the packet is encrypted
7196 as soon as possible and left to the queue. The queue is then
7197 just purged into wire. There won't be any fixes for this
7198 any time soon. So, the current semantic for packet sending
7201 o If you send packet to remote host and do not force the send
7202 (the packet will be in queue) then all subsequent packets to the
7203 same remote host must also be put to the queue. Only after the
7204 queue has been purged is it safe again to force the packet
7207 o If you send all packets immediately then it safe to send
7208 any of subsequent packets through the queue, however, after
7209 the first packet is put to queue then any subsequent packets
7210 must also be put to the queue.
7212 Follow these rules and everything works fine.
7214 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7216 * Added new function silc_server_remove_clients_by_server to
7217 remove all client entries from ID list when the server connection
7218 is lost. In this case it is also important to invalidate all
7219 client entires as they hold the invalid server entry. This
7220 fixes fatal bug when server has lost connection and will reconnect
7223 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7225 * Made some sanity checks to silc_server_daemonise like to check
7226 whether the requested user and group actually exists.
7228 * Added sanity check to SKE's silc_ske_responder_finish to check
7229 that the public and private key actually is valid.
7231 * Invalidate the client's nickname when receiving Replace ID
7232 packet and the Client ID is being replaced. This means that the
7233 server will query the nickname if someone needs it (client)
7236 * Sort the ID Cache in client library when the ID Cache data
7237 has changed (needs sorting).
7239 * Do not allow for SILC client to create several connections to
7240 several servers. The client does not support windows right now
7241 and generating multiple connections causes weird behaviour.
7243 Irssi-silc client does support windows and can handle several
7244 connections without problems, see: www.irssi.org and SILC plugin.
7246 * Fixed some places where client was added to the IDList. The
7247 rule of thumb is following (in order to get everything right):
7248 If the client is directly connected local client then the
7249 `connection' argument must be set and `router' argument must be
7250 NULL to silc_idlist_add_client function. If the client is not
7251 directly connected client then the `router' argument must
7252 bet set and the `connection' argument must be NULL to the
7253 silc_idlist_add_client function.
7255 * The funtion silc_server_packet_send_local_channel actually did
7256 not check whether the client was locally connected or not. It
7257 does that now. Fixed a bug related to LEAVE command.
7259 * Fixed Remove Channel User payload parsing bug in server's
7260 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
7262 * The server's silc_server_save_channel_key now checks also the
7263 global ID list for the channel as it might not be in the local
7264 list. Fixed a bug related to LEAVE command.
7266 * Is this the end of the [<unknown>] buglet that has been lurking
7267 around for a long time? A little for loop fix in server's
7268 silc_server_command_whois_parse that is used by both IDENTIFY
7269 and WHOIS command. At least, this was a clear bug and a cause
7270 of one type of [<unknown>] buglet.
7272 * WHOIS and IDENTIFY commands call the function
7273 silc_server_command_[whois/identify]_check function even if
7274 we are not router server.
7276 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7278 * Added --with-gmp configuration option. If set the GMP
7279 is always compiled in the SILC source tree. If not set then
7280 it is checked whether the system has the GMP3 installed. If
7281 it has then the GMP won't be compiled (the system's headers
7282 and library is used), if it doesn't have it then the GMP is
7283 compiled in the SILC source tree.
7285 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7287 * Changed RSA private exponent generation to what PKCS #1
7288 suggests. We try to find the smallest possible d by doing
7289 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
7290 not security fix but optimization.
7292 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7294 * Added new config entry [Identity] to fork the server and run
7295 it as specific user and group. A patch from Bostik.
7297 * Imported Dotconf configuration library into lib/dotconf.
7298 This will be used to create the SILC configuration files later.
7299 It will appear in the distsribution after this commit.
7301 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7303 * A big code auditing weekend happening. Auditing code for
7304 obvious mistakes, bugs and errors. Also, removing any code
7307 Removed files for being obsolete:
7309 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
7310 inline in the file lib/silcutil/silcbuffer.h)
7312 o lib/silcutil/silcbufutil.c (the header has inline versions)
7314 Changed code to fix possible error conditions:
7316 o The buffer formatting routines now check that the destination
7317 buffer really has enough space to add the data. This applies for
7318 both buffer formatting and unformatting
7319 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
7320 unformatting was changed to accomodate following rules:
7321 XXX_*STRING_ALLOC will allocate space for the data into the pointer
7322 sent to the function while XXX_*STRING will not allocate or copy
7323 the data into the buffer. Instead it sets the pointer from the
7324 buffer into the pointer sent as argument (XXX_*STRING used to
7325 require that the pointer must be allocated already). This change
7326 makes this whole thing a bit more consistent and more optimized
7327 (note that the data returned in the unformatting with XXX_*STRING
7328 must not be freed now). The routines return now -1 on error.
7330 o Tried to find all code that use buffer_format and buffer_unformat
7331 and added return value checking to prevent formatting and
7332 especially unformatting errors and possible subsequent fatal
7335 o Changed ske->x and ske->KEY to mallocated pointers in
7336 lib/silcske/silcske.h. Fixed possible data and memory leak.
7338 o Added return value checking to all *_parse* functions. Fixed
7339 many memory leaks as well.
7341 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
7342 so that buffer overflows would not happen. All code now also
7343 checks the return value as it can fail.
7345 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7347 * Added reconnection support to server if the normal server looses
7348 its connection to the router (for example if router is rebooted).
7349 The server performs normal reconnection strategy implemented
7350 to the server. Affected file silcd/server.c.
7352 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7354 * Added new packet type SILC_PACKET_SET_MODE that is used to
7355 distribute the information about changed modes (for clients,
7356 channels and clients channel modes) to all routers in the
7357 network. Updated the protocol specification accordingly.
7359 Added functions into silcd/packet_send.c and
7360 silcd/packet_receive.c: silc_server_send_set_mode,
7361 silc_server_set_mode.
7363 Added new files silcmode.[ch] into lib/silccore that implements
7364 the encoding and decoding of Set Mode Payload. Added new type
7365 SilcSetModePayload. Moved the definitions of different modes
7366 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
7368 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7370 * Oops, a little mistake in server's connection authentication
7371 protocol. The protocol is not ended with FAILURE but with
7372 SUCCESS if the authentication is Ok. :) Affected file is
7375 * Implemented NICK_CHANGE notify handling in server in the file
7376 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
7377 the local clients on the channel. After the changing nickname
7378 in router environment snhould work and the [<unknown>] nickname
7379 should appear no more.
7381 The silc_server_replace_id function that receives the Replace ID
7382 payload now sends the NICK_CHANGE notify type also in the file
7383 silcd/packet_receive.c
7385 * Changed WHOIS and IDENTIFY command to support the maximum amount
7386 of arguments defined in protocol specs (3328 arguments). This
7387 fixed a bug that caused problems when there were more than three
7390 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7392 * Added extra parameter, command identifier, to the
7393 silc_client_send_command so that explicit command identifier
7396 Changed that ID list routines uses specific command identifier
7397 when sending WHOIS/IDENTIFY requests to the server so that they
7398 can be identified when the reply comes back.
7400 Affected files lib/silcclient/command.[ch],
7401 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
7403 * Added `sender' argument to silc_server_packet_send_to_channel
7404 to indicaet the sender who originally sent the packet to us
7405 that we are now re-sending. Ignored if NULL. Affected file
7406 silcd/packet_send.[ch].
7408 * Added some server statistics support in silcd/server_internal.h
7409 SilcServerStatistics structure and around the server code. Also
7410 send some nice statistics information when client is connecting
7413 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7415 * Fixed channel ID decoding in server's JOIN command reply in
7416 silcd/command_reply.c
7418 * Fixed braodcasting of replace ID payload to not to send it if
7419 we are standalone server in silcd/packet_receive.c.
7421 * Fixed all channel message sending routines to not to send
7422 packets to clients that has router set, since they are routed
7423 separately in the same function earlier. Affects file
7424 silcd/packet_send.c and all channel packet sending functions.
7426 * In USERS reply, res_argv[i] are not allocated, the table
7427 is allocated. Thus changed that free the table, not its
7430 * In server's whois_check and identify_check if the client is
7431 locally connected do not send any WHOIS commands - they are not
7434 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7436 * Fixed some minor bugs in client when sending WHOIS command. The
7437 arguments was in wrong order.
7439 * Removed statis function add_to_channel from server in
7440 silcd/command.c that was previously used with the joining but
7443 * Tested USERS command in router environment successfully with two
7444 routers, two servers and two clients.
7446 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7448 * Reorganized the USERS command and command reply in client library
7449 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
7450 When the command is given by user we register a pending command
7451 callback that will reprocess the command after the reply has been
7452 received from the server. When reprocessing the packet we then
7453 display the information. Thus, the USERS information is displayed
7454 now in the command callback instead of in the command reply
7455 callback. The processing of the command is same as previously
7456 when server has sent the command reply in the JOINing process.
7458 * Added to USERS command in silcd/command_reply.c to join the client,
7459 we didn't use to know about, to the channel after we've created
7460 a client entry for it. Also, for clienet we did know already still
7461 check whether it is on the channel or not and add it if not.
7463 * Removed silc_server_command_join_notify as the function and its
7466 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7468 * Changed the client's pending command handling to the same as the
7469 server's pending command handling. It is also now possible to
7470 execute command reply functions from other command reply
7471 function as the function callbacks for commands and command
7472 replies are one and same. The pending commands are not static
7473 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
7474 in client connection context. Thus, pending commands are server
7475 connection specific as it is convenient.
7477 Changed the function silc_client_command_pending and
7478 silc_client_command_pending_del and added new function
7479 silc_client_command_pending_check. Removed the
7480 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
7483 * Added cmd_ident, current command identifier, to the client
7484 connection context in lib/silcclient/client.h to keep track on
7485 command identifiers used in command sending. Client's command reply
7486 function handling now supports the mandatory command identifiers.
7488 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
7489 funtions in client to fully support pending command callbacks.
7491 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
7492 as one of the arguments to the application in the command reply
7495 * NOTE: The FORWARDED flag is depracated. It used to be depracated
7496 before first releasing SILC but came back. Now it is removed again
7497 and should come back nomore. The FORWARDED flag was used only
7498 by the JOINing procedure by forwarding the command packet to router.
7499 Now, the JOINing procedure has been changed to more generic (due
7500 to various router environment issues) and FORWARDED is not needed
7501 anymore for anything. The protocol specification is yet to be
7504 Now, removed silc_server_packet_forward from server and the flag
7505 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
7507 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7509 * Renamed NAMES command to USERS command. The NAMES was named that
7510 due to historical reasons. Now it is renamed. Also, rewrote
7511 parts of the USERS command. The nickname list is not sent anymore
7512 by the server. Only Client ID and mode lists are sent in the USERS
7513 command. Changed this also to the protocol specification.
7515 The client now resolves the names and stuff after it receives
7516 the USERS list from the server when joining to the channel.
7518 * WHOIS and IDENTIFY commands has been changed to support multiple
7519 Client ID's per command. One can now search for multiple users
7520 in the network by sending only one WHOIS or IDENTIFY command.
7521 Changed the code and the protocol specifications.
7523 * Removed silc_server_command_identify_parse and changed that IDENTIFY
7524 uses silc_server_command_whois_parse to parse the request. */
7526 * If normal server, do not parse the WHOIS and IDENTIFY requests
7527 before sending it to the router. Saves some time.
7529 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7531 * Fixed JOIN command on client library. Wrong number of arguments
7532 used to crash the client.
7534 * Added silc_server_channel_has_global function to check whether
7535 channel has global users or not.
7537 * Added silc_server_channel_has_local function to check whether channel
7538 has locally connected clients on the channel.
7540 * The silc_server_remove_from_one_channel now checks whether the
7541 channel has global users or not after given client was removed from
7542 the channel. It also checks whether the channel has local clients
7543 on the channel anymore. If it does not have then the channel entry
7544 is removed as it is not needed anymore.
7546 * The silc_server_notify now checks on JOIN notify whether the joining
7547 client is one of locally connected or global. If it is global then
7548 the channel has now global users on the channel and that is marked
7549 to the channel entry. Also, it now saves the global client to
7550 global list who is joining and JOINs it to the channel. This is
7551 for normal server, that is.
7553 Changed silc_server_send_notify_on_channel,
7554 silc_server_packet_relay_to_channel and
7555 silc_server_packet_send_to_channel check if we are normal server
7556 and client has router set (ie. global client) do not send the
7557 message to that client, as it is already routed to our router.
7559 * Implemented LEAVE notify type handling in silc_server_notify
7562 * Tested LEAVE command in router environment successfully. Tested
7563 with two routers, two servers and two clients.
7567 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
7569 * Implemented SIGNOFF notify type handling in silc_server_notify
7572 * silc_server_remove_id now removes the client entry from all channels
7573 it has joined and thusly sends SIGNOFF notify type.
7575 * Rewrote the NAMES list generation in server by removing two excess
7576 loops. The lists are created now inside one loop.
7578 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7580 * silc_server_remove_channel_user checks now also global list
7581 for channel and client.
7583 * silc_server_new_channel_user checks now both local and global
7584 list for channel and client. Fixed a bug in client id decoding.
7585 Used to decode wrong buffer.
7587 * silc_server_channel_message checks now both local and global
7588 list for channel entry.
7590 * Tested channel joining (hence JOIN) in router environment
7591 successfully. Tested with two routers, two servers and two
7594 * Tested channel message sending in router environment successfully.
7596 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7598 * Added silc_server_save_channel_key into server.[ch] to save the
7599 received channel key in Channel Key payload processing. It is
7600 also used in JOIN command reply handling.
7602 Equivalent function silc_client_save_channel_key added into
7603 client.[ch] into client library.
7605 * Changed JOIN command reply to send information whether the channel
7606 was created or not (is existing already) and the channel key
7607 payload. Changed protocol specs accordingly.
7609 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
7610 the request was sent by ID and not by nickname. Crashed on
7613 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7615 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
7616 now correctly save the received data.
7618 * silc_server_free_sock_user_data now notifies routers in the
7619 network about entities leaving the network.
7621 At the same time implemented functions silc_server_remove_id
7622 and silc_server_send_remove_id to receive and send REMOVE_ID
7623 packets. The packet is used to notify routers in the network
7624 about leaving entities. The ID removed will become invalid in
7627 * Added function silc_idlist_del_server into server. Removes and
7628 free's server entry from ID list.
7630 * silc_server_private_message function now checks, if we are router,
7631 that the destination ID really is valid ID, naturally.
7633 * In router when NEW_ID packet is received (for new client) the
7634 hash of the Client ID is saved in the ID Cache but the
7635 client->nickname is set to NULL, instead of putting the hash
7638 IDENTIFY command now also checks that client->nickname must be
7639 valid. If it is not if will request the data from the server who
7640 owns the client. Added new function
7641 silc_server_command_identify_check.
7643 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
7644 to set the command to already allocated Command Payload.
7646 * Tested private message sending in router environment with two
7647 routers, two servers and two clients. Fixed minor bugs and now
7650 * Fixed segfault from client's NAMES command. Used to crash if
7653 * Forwarded packets must not be routed even if it is not destined
7654 to the receiver. Changed server code comply with this.
7656 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7658 * Added `require_reverse_mapping' boolean value to ServerParams
7659 structure. If TRUE (not default) the server will require that
7660 the connecting host has fully qualified domain name.
7662 If the reverse mapping is not required and hostname could not be
7663 found the IP address is used as hostname.
7665 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7667 * Implemented version string checking to both client and server.
7668 The check is incomplete currently due to the abnormal version
7669 strings used in development version of SILC.
7671 * Changed all command functions in server to use the new
7674 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7676 * Changed char *data to unsigned char *data in ID Cache system to
7677 support binary data as ID Cache data. Changed code to support
7678 binary data in lib/silccore/idcache.c.
7680 * Renamed silc_server_packet_relay_command_reply to
7681 silc_server_command_reply as it is normal packet receiving
7682 function. Rewrote the function to accept command replys for
7683 servers and not only for clients.
7685 * Mark remote router always as registered server if we are connecting
7686 to it. Otherwise, commands sent by the router to us are ignored.
7688 * All ID List find routines now returns the ID Cache Entry pointer
7689 as well if requested.
7691 * WHOIS command works now in router environment, tested with two
7692 routers, two servers and two clients.
7694 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
7695 in router environment (as it is almost equivalent to WHOIS) but
7696 hasn't been tested thoroughly. Added new functions:
7698 silc_server_command_identify_parse
7699 silc_server_command_identify_send_reply
7700 silc_server_command_identify_from_client
7701 silc_server_command_identify_from_server
7703 * Disabled route cache adding because adding two different ID's with
7704 same IP replaces the old cache entry thus giving wrong route.
7705 The entry->router->connection is always the fastest route anyway
7706 so route cache may not be needed. Of course, new routes maybe
7707 established after receiving the ID when the entry->router->connection
7708 might not be anymore the most optimal.
7710 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7712 * Add route cache for received ID for fast routing.
7714 * Added silc_server_packet_route to route received packet on router
7715 that is not destined to us.
7717 * Renamed silc_server_get_route to silc_server_route_get.
7719 * Added id_string and id_string_len fields into SilcServer to
7720 include encoded ServerID for fast comparing without excess
7721 encoding of the ID's.
7723 * Cleaned up WHOIS command on server side. Added following static
7726 silc_server_command_whois_parse
7727 silc_server_command_whois_check
7728 silc_server_command_whois_send_reply
7729 silc_server_command_whois_from_client
7730 silc_server_command_whois_from_server
7732 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
7733 arguments in command replies. All command functions should be
7734 updated to use this macro.
7736 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7738 * Minor typo fixes on command reply handling on server.
7740 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7742 * Added silc_server_command_add_to_channel internal routine to add
7743 the client to the channel after router has created the channel and
7744 sent command reply to the server.
7746 * Added generic silc_server_send_command to send any command from
7749 * Use static buffer with ID rendering instead of duplicating data.
7751 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7753 * Fixed a channel user mode bug when joining to a channel server gave
7754 everybody channel founder rights, oops.
7756 * We mark ourselves as the router of the incoming server connection
7757 if we are router ourselves. This way we can check in some packet
7758 sending functions whether it is locally connected server. For
7759 incoming router connections we put NULL.
7761 * For router sending packets locally means now always sending the
7762 packet cell wide; to local clients and local servers. For normal
7763 server sending packet locally means sending it to only local
7766 * Fixed the JOIN command to really work in router environment. If the
7767 channel is created it is always created by the router. Router is
7768 also responsible of making the initial joining to the channel,
7769 sending JOIN notify to the sending server and distributing
7770 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
7771 does not exist server doesn't do anything else but forward the
7772 command to the router which performs everything.
7774 * Added silc_server_send_channel_key function to send the Channel Key
7777 * Added silc_server_create_channel_key to create new channel key. The
7778 channel key is now re-generated everytime someone joins or leaves
7779 a channel, as protocol dictates. Note: channel->key_len is the
7782 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7784 * Splitted server.[ch] finally. Created now packet_send.[ch] and
7785 packet_receive.[ch] to separate packet sending and receiving
7786 routines. The server.[ch] now includes everything else including
7787 actual packet processing (writing and reading data) and other
7790 Renamed silc_server_private_message_send_internal to
7791 silc_server_send_private_message. The routine is still though
7792 used only to relay private messages as server does not send
7793 private messages itself.
7795 Renamed silc_server_new_channel to silc_server_create_new_channel
7796 and added new function sicl_server_new_channel that handles the
7797 incoming New Channel packet. Added also new sending function
7798 silc_server_send_new_channel to send New Channel Payload.
7800 * Added new function silc_server_notify to process incoming notify
7801 packet to the server/router. Server may then relay the notify
7802 to clients if needed.
7804 * Added new function silc_server_new_channel_user to process incoming
7805 New Channel User packet. Router will redistribute the packet and
7806 send JOIN notify to its local clients and locally connected servers
7807 if needed. Normal server will send JOIN notify to its local client
7808 on same channel when received this packet. Added also corresponding
7809 sending function silc_server_send_new_channel_user to sent the
7812 * Added boolean route argument to send_notif_to_channel and
7813 packet_send_to_channel functions to attempt to route the packet
7814 if it is TRUE and send only locally if it is FALSE.
7816 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7818 * silc_server_replace_id now broadcasts the received replace ID
7819 packet if it is not broadcast packet already. The router must
7820 broadcast to inform other routers about changed ID.
7822 * Added backpointer to server's router into SilcServer context in
7823 silcd/server_internal.h.
7825 * Fixed silc_server_packet_broadcast to send correct broadcast
7828 * The channel key is now distributed to the local client as soon
7829 as it is received from the router (in router environment) so that
7830 no other packet may be sent for the channel until client has
7833 * silc_server_remove_channel_user now broadcasts the received
7834 Remove Channel User packet if it is not broadcast packet already.
7835 The router must broadcast to inform other routers about removed
7838 * Added users field into SilcPacketContext that is a reference count
7839 of the context. One can increase the reference count by calling
7840 silc_packet_context_dup which is now changed to just increase the
7841 reference count instead of duplicating the data. The reference
7842 count is decresed by calling silc_packet_context_free that will
7843 free the data after the reference count hits zero.
7845 For now on the packet context and everything allocated into it
7846 (including the raw packet from network) must be freed by calling
7847 the new silc_packet_context_free function. Added also new function
7848 silc_packet_context_alloc that must be used now to allocate the
7849 context. This also means that if a routine is asynchronous from
7850 silc_[client/server]_packet_parse_type the packet context must
7851 be duplicated by calling silc_packet_context_dup. Otherwise it
7852 gets free'd after silc_[client/server]_packet_parse_type returns.
7853 Also, one must remember that if packet is duplicated then its
7854 reference count must be decresed by calling the free function as
7855 many times as it was duplicated.
7857 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7858 from both client and server.
7860 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7862 * Made joining to a channel working in router environment.
7864 * Cleaned up JOIN command on server side and create function
7865 silc_server_command_join_channel internal routine to make the
7868 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7870 * Changed silc_command_pending list to SilcDList. Also, added
7871 `ident' field to SilcServerCommandPending structure to identify
7872 the reply and to call correct callback.
7874 Added silc_server_command_pending_check function to replace the
7875 corresnponding macro. The silc_command_pending list is not
7878 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7879 to set identifier to previously allocated Command Payload. It
7880 is used to set identifier for command when resending Command
7883 * Added silc_command_payload_encode_payload to encode Command
7884 Payload buffer from SilcCommandPayload structure.
7886 * Added silc_argument_payload_encode_payload to encode Argument
7887 payload buffer from SilcArgumentPayload structure.
7889 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7891 * Changed WHOIS command to support router connection on server side.
7892 The whois request is always sent to router unless the server is
7893 standalone server. After server has received the reply from the
7894 router will it send the reply to the client.
7896 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7897 broadcast received broadcast packet. The function is used only
7898 by router. The broadcast packet is always sent to the router's
7901 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7902 render given ID to printable string, for log files for example.
7904 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7906 * Made basic router to router connections working. At least they
7907 can now connect to each other but nothing really works the way
7908 they are supposed - yet.
7910 * Added new initiator token to RouterConnection configuration
7911 file in silcd/serverconfig.[ch]. It is used to tell whether we
7912 are the initiator to the remote router or whether we'll expect
7913 the other end to connect.
7915 * Moved registering of listener task to silc_server_init, hence
7916 the server starts listenning as soon as it is run, even if it
7917 does not have connections to other routers. Let's see how well
7920 * Changed default connection retry timeouts for more suitable in
7923 * Removed cipher and such arguments from silc_idlist_add_client
7924 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7925 Added new function silc_idlist_add_data to add the keys and stuff
7928 * Added SilcIDListData structure and added it to SilcClientEntry
7929 and SilcServerEntry as their first field in the structure. This
7930 way we can explicitly cast the ID entries to the SilcIDListData
7931 structure and get common data for the entries. In past, we had
7932 to first check what type of connection it is and then cast it to
7933 correct ID entry type. Now, we can directly cast the opaque
7934 pointer to the SilcIDListData (no matter what ID entry it actually
7935 is) and get the data needed.
7937 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7939 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7940 in some circumstances even if threre were timeout tasks, though not
7941 IO tasks, but tasks anyway. Now fixed.
7943 * Defined SilcServerConnection structure to hold connection specific
7944 stuff about directly connected servers and routers. The definition
7945 is currently in silcd/server_internal.h. I thought about having
7946 a bit more important role fro this struct but for now it is used
7947 only when connecting to other server (or router actually).
7949 * Added connecting retry support in server when connecting to
7950 router(s). The retry feature implement exponential backoff
7951 algorithm. Also, added SilcServerParams structure to hold default
7952 parameters for server. For now, it include these retry settings
7953 and are hard coded. After server is moded to be as Silc Server
7954 Library this structure will be more important.
7956 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7958 * Changed client librarys channel->clients table to SilcList and
7959 changed code accordingly.
7961 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7963 * Changed client's channel table to SilcList and changed code
7964 accordingly. Also changed SilcChannelClientEntry to include back-
7965 pointer to the channel so that client entry can use that structure
7966 as list as well and we have fast cross-reference to the channel.
7967 This change dramatically decreased the complexity of channel
7968 handling with client entry and vice versa (removed one extra
7969 loop when searching for channel entry from many functions).
7971 * Changed server->sim from table to SilcDList and changed code
7974 * NAMES command can now be used from user interface. It will show
7975 the user list on the channel, neatly.
7977 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7978 Code now saves realname of the user if it becomes available.
7980 * Renamed configure.in to configure.in.pre and made ./prepare
7981 script to automatically add correct version string to
7982 configure.in which it creates from configure.in.pre.
7984 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7986 * NAMES command reply now shows users mode with the nickname when
7989 * Moved silc_client_ch[u]mode[_char] functions from
7990 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7991 place sucks, they are utility functions and should be in some
7994 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7996 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7999 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8003 * Added TRQ (efficient deque and list library) into lib/trq. This is
8004 a very good list library that is currently used in the SILC. Defined
8005 SilcList API over the library because I didn't like the API very
8006 much. See lib/trq/silclist.h for the API and examples of how to
8007 use the API. Fixed various places in the code to use the new
8008 SilcList API. The SilcList is meant for lists that has a structure
8009 already defined as a list. It is not suitable to add just some
8010 context to the list (in TRQ, the context is the list actually).
8012 So, I defined SilcDList that can be used for the purpose where
8013 predefined list structure does not exit. This can be used as
8014 such list. Now some context just can be added to the SilcDList.
8015 Currently this list is not used in the SILC just yet, though there
8016 are a lot places where this can replace dynamically allocated
8017 tables and I will fix these places, later, to use SilcDList.
8018 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
8019 and use TRQ internally).
8021 Also fixed some annoying warning messages that the original TRQ
8022 code generated. Also minor changes to TRQ's Makefile.in.
8024 * Added support for querying by Client ID to both WHOIS and
8025 IDENTIFY commands into server, as required by the protocol.
8027 * Removed method function pointers from SilcBuffer structure. They
8028 weren't used to anything and just increased the context size for
8029 no good reason. This change also made silc_buffer_alloc and
8030 silc_buffer_free functions inline functions.
8032 * Disabled command flooding detection support until it's fixed so
8033 that it accepts commands in but does not execute them more than once
8036 * Added silc_net_localhost(), to return local hostname, into
8037 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
8038 that must be initialized before calling silc_client_init.
8040 * Added new function: silc_server_send_notify_on_channels to send
8041 notify messages to all channels client has joined. It is assured
8042 that the message is sent only once per client.
8044 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
8045 lib/silcutil/silcutil.[ch] as silc_format function. The new
8046 function is generic and is used by server as well, not only by
8047 the logging routines.
8049 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
8050 the provided version string was not acceptable. Added new function:
8051 silc_ske_check_version into lib/silcske/silcske.h. The function
8052 must be implemented by the application (client or server) and it
8053 does not reside in the SKE library. The function checks the version
8054 string remote end sent.
8056 * Added back pointers (to opaque context and to SilcSocketConnection)
8057 into SilcPacketContext structure into lib/silccore/silcpacket.h.
8059 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
8060 duplicate packet context structure.
8062 * Changed `notify' client operation to send same arguments as client
8063 receives from server except for ID's. ID's are mapped to correct
8064 ID entry and that is returned. Also, if channel entry is not sent
8065 by server but the notify is for channel the channel entry is sent
8066 to application (otherwise application doesn't know that it is for
8067 channel (library gets it from packet's Destination ID)).
8069 * Added silc_client_remove_from_channels into client library to
8070 remove a client from all channels it has joined to. Used when
8071 received SIGNOFF notify from server. Added also new function
8072 silc_client_replace_from_channels to replace old ID entry with
8073 new ID entry on all channels. Used when received NICK_CHANGE
8076 * Fixed ID Cache list handling in silc_idlist_get_client in
8077 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
8078 to get (or query) client by ID.
8080 * Updated TODO list.
8082 * Added connection authentication status message defined by the
8083 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
8084 support for these into the code in client and server side.
8086 * Added generic function silc_client_send_command to send any command
8087 with variable argument list. Application should use this function
8088 to send commands if the command functions provided by the library
8089 does not suite for the application's user interface needs.
8091 * Added new `failure' client operation. Application is notified about
8092 received failure packet if client is executing a protocol. In this
8093 case the protocol's execution has failed.
8095 * Added SKE's end notify to send the SKE_SUCCESS notify message that
8096 is required by the protocol.
8098 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
8099 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
8102 * Added status flag to SilcSKE object to indicate realtime status
8103 of the SKE protocol.
8105 * Application receives now exactly same command reply arguments as
8106 the library receives from server. However, if ID is received the
8107 corresponding ID entry is returned to the application (eg. Client
8108 ID is mapped to correct SilcClientEntry entry and that is returned).
8109 Changed command_reply client operation due to this change.
8111 * Changed all ID's in commands and in command replys as ID Payloads.
8112 Change affected both client and server side codes.
8114 All ID's sent in SILC network (with execption of ID's in SILC
8115 Packet header) are sent in ID Payload to support variable length
8118 * Server now notifies nick changes and notifies all clients on
8119 the channels about the new nickname (about the new Client ID,
8122 * Implemented CMODE command to change channel modes. Supports all
8123 channel modes defined by the protocol specs except ban and invite
8124 lists. (Also, private channel key mode is supported but support for
8125 setting private channel key in client is missing, thus, this mode
8126 has no effect on client side (except that server requires that the
8127 client uses private channel key and normal channel traffic does not
8130 Also, invite mode works per se, but INVITE command does not work
8131 yet correctly, so you can set channel as invite only channel but
8132 inviting clients to the channel does not work (it is yet to be
8133 thought what's the best way to do it).
8135 * Added new command SILC_COMMAND_CUMODE to change user mode on the
8136 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
8137 Implemented CUMODE command to change user's mode on the channel.
8138 Supports all modes defined by the protocol specs.
8140 * Added NAMES command reply to return users modes on the channel.
8142 * Removed unnecessary and slow ciphers from lib/silccrypt.
8144 * Set SO_KEEPALIVE option to connection sockets by default.
8146 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
8148 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
8149 redefined the Notify Payload into protocol specs.
8151 * Added silc_id_payload_parse_id to get ID directly from raw
8154 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8156 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
8157 accept searching by Client ID as well.
8159 * Added support for LEAVE and SIGNOFF notify types in client library.
8161 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
8162 to parse ID Payload from raw data.
8164 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8166 * Added flags parameter into silc_ske_assemble_security_properties
8167 function in lib/silcske/silcske.[ch].
8169 * Changed notify client operation to fit better for notify messages
8170 sent by server. The notify payload received from server is now
8171 passed to the application (after parsing it to SilcNotifyPayload).
8172 It is application's responsibility to retrieve the arguments
8173 from the payload and show the message the way it wants. The message
8174 sent by server is implementation specific.
8176 * Changed public keys to comply with the protocol specification.
8177 Old public keys are not supported anymore and are not compatible.
8179 * Removed nickname from Channel Payload as the latest draft removed
8180 it. The client must resolve the nickname from the NAMES command
8181 reply received when it joined the channel.
8183 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
8185 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8187 * Fixed some errors in protocol specification drafts.
8189 * Created lib/silccore/silcnotify.c to implement Notify Payload
8190 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
8191 generic payloads described by protocol specifications. The file
8192 includes implementations for ID Payload and Argument Payload.
8194 * Changed Command Payload implementation to use the new Argument
8195 Payload. Changed command_xxxx_payload to command_payload_xxxx
8196 to comply with SILC coding conventions.
8198 * Added suppport for Argument Payload handling in Notify Payload
8199 implementation as protocol requires it. Added the new support
8200 into server and client lib as well.
8202 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8204 * Added support for multiple nicknames on same channel. [n] is
8205 added locally to the nickname if there are more than one same
8206 nicknames on the channel.
8208 * Server now sends all nicknames that matched WHOIS request.
8209 Client also shows the list received from server.
8211 * Added TOPIC command to client side. User can now set and show
8212 current topic on channel.
8214 * Added MOTD command to client and server. Also, server sends the
8215 motd when client connects to the server.
8217 * Changed version strings to comply ISO 8601.
8219 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8221 * Fixed protocol error handling in client library. It should now
8222 cope even if the SKE fails for some reason.
8224 * Made new protocol specification drafts for submitting to IETF.
8226 * Implemented TOPIC command to server in silcd/command.c.
8228 * Added two new notify types into lib/silccore/silcnotify.h:
8229 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
8230 notify nickname change and topic setting/change on a channel.
8232 * API change of command_reply operation in client library. The
8233 application gets now the status type received from server as well.
8235 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8237 * Removed the function just added to lib/silcutil/silcschedule.[ch].
8239 * Cras fixed and optimized the packet handling even further and
8240 it should work now. Minor change to the prototype of function
8241 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
8243 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8245 * Added new function into lib/silcutil/silcschedule.[ch]:
8246 silc_schedule_with_fd to select() a specified fd. The function
8247 returns after timeout expires or data arrives or goes. The
8248 function is used by packet routines to wait that all data is
8249 received from network.
8251 * Fixed data reading from network in lib/silccore/silcpacket.c.
8252 The code now assures that all data is read from the fd and then
8253 continues packet processing. This was a bug fix since the code
8254 used to drop some data in some circumstances.
8256 * Added new function into lib/silcclient/client.[ch]:
8257 silc_client_start_key_exchange to start key exchange after
8258 connection has been established to server. The code internally
8259 now uses this funtion but its main purpose was to provide it
8260 for applications that perform their own connecting. After
8261 application has created a connection it merely calls this
8262 function to start the key exchange between client and server.
8263 The library takes care of everything else after that.
8265 Updated also lib/silcclient/README to explain the usage of
8268 * Do not send to application information that connection has
8269 been established. Application gets notified it by connect
8272 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8274 * Applied cras's patch to add silc_schedule_one function. The
8275 function runs scheduler once and returns.
8277 * Fixed the scheduler after cras messed it up. The timeout
8278 handling works now as it's supposed to work.
8280 * Added into lib/silccore/ silcnotify.h to include notify
8281 message types support. Changed silc_server_send_notify*
8282 functions, in server.[ch], to support those new notify types.
8283 Added the support for the notify types into client library,
8284 as well. Added new notify client operation into ops.h in
8287 * Changed silc_server_packet_send_to_channel to send normal
8288 packets instead of just channel message packets. The function
8289 is now used to send the notify packets to channels. It is not
8290 used to send channel message packets anymore, as server never
8293 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
8294 va_arg()s as it seems to require it nowadays. I guess, if SILC
8295 is compiled with older va_arg() the new code should work anyway.
8297 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8299 * Splitted core library. Core library (lib/silccore) includes
8300 now only SILC protocol specific core (and common) components.
8301 Created new utility library (lib/silcutil) that includes more
8302 generic purpose stuff. The stuff for util library was taken
8303 from the old core library. This was minor and easy split.
8305 * Created SILC Client Library (lib/silcclient) that includes
8306 implementation of the SILC client without user interface. This
8307 was major move from silc/ directory. The code has been changed
8308 so that it is transparent towards the user interface. The
8309 silc/ directory includes now the same user interface as before
8310 and it uses the new client library. Read lib/silcclient/README.
8311 Basicly, the client library performs everything else related
8312 to SILC except user interface handling. Also, configuration
8313 files are considered to be part of user interface and library
8314 does not handle them.
8316 This change also changed a lot of structures, function naming etc.
8317 Most important change was that SilcClientWindow object was
8318 renamed to SilcClientConnection in the client library. Created
8319 also new file lib/silcclient/ops.h. Also added new files
8320 silc/local_command.[ch] and silc/client_ops.[ch].
8322 All these changes were made to make it easier for user interface
8323 designers to create what ever user interface for the SILC client
8326 It is also expected that the server will be moved to lib
8327 directory as well and SILC Server Library will be created;
8328 sometimes in the future.
8330 * Removed Local commands from lib/silccore/silccommand.h as
8331 they are application specific and new client library does not
8332 handle any of those anymore.
8334 * Several functions moved to lib/silcutil/silcutilc.[ch] from
8335 old client implementation in silc/.
8337 * Added support for callback functions in SILC_LOG_* macros.
8338 Application can now set its own callbacks that will be called
8339 instead of using the default functions that will always print
8340 the debug messages to stderr (or stdout). Also, debugging can
8341 now be disabled by setting silc_debug to FALSE and re-enabled by
8342 setting it to TRUE. Note, that logging will still work even
8343 if debugging is disabled.
8345 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
8346 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
8347 silc_log_reset_debug_callbacks.
8349 * To enable debugging in silc client one must give now -d
8350 option on command line.
8352 * Changed silc_schedule_init to automatically allocate task queues
8353 if they are not allocated before calling it.
8355 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8357 * Added GMP 3.1 into math library.
8359 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8361 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
8362 a channel in SILC network. The packet is used by servers and
8363 routers to notify other routers that user has left a channel.
8364 This little feature was missing until now. Added the feature
8365 to protocol specification as well.
8367 Added functions: silc_server_send_remove_channel_user and
8368 silc_server_remove_channel_user into server.[ch].
8370 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
8371 lib/silccore/silcpacket.h. However, they are not implemented
8374 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8376 * Fixed joining to a channel and sending channel messages
8377 between server and router. The channel message sending should
8378 now work inside a cell.
8380 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8382 * Fixed the private message sending between server and router.
8383 The private message sending should now work inside a cell.
8385 * Added silc_server_replace_id into server.[ch] to replace
8386 existing ID in the SILC network.
8388 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
8389 and silc_idlist_replace_server_id into idlist.[ch] in server.
8391 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8393 * Fixed the server to server connections. Server can again now
8394 connect to router. Router to router connections probably does
8397 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8399 * Added dynamic protocol registering support. Now protocols can
8400 registered and unregistered on the fly. Patch by cras.
8402 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8404 * Added lib/contrib directory to hold routines that some platforms
8405 don't have but are needed by SILC.
8407 * Added getopt.c, getopt1.c and getopt.h from GNU C library
8408 into lin/contrib to provide getopt() and getopt_long() for
8409 those who don't have it.
8411 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8413 * Added AWAY command to client. When away message is set and
8414 client receives a private message packet the client automatically
8415 replies to the sender with the away message.
8417 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
8418 bug seemed to be the cause of recent problems when compiling
8421 * Added version detection support to SKE protocol specification
8422 and added the new changes to the SKE implementation as well.
8423 There were other minor changes in the SKE protocol as well.
8425 Many changes in lib/silcske/silcske.[ch] and in
8426 lib/silcske/payload.[ch].
8428 * Added ^U functionality, clear input line. Patch from cras.
8430 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8432 * Mainly small bugfixes on core library. Fixed some debugging
8433 logging and buffer overflow in silclog.c.
8435 * Updated config.sub and config.guess on the distribution tree.
8437 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8439 * Added command lagging support in server. Client may execute
8440 commands now only once in two seconds.
8442 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8444 * Optimized packet reception. MAC computation and checking is now
8445 also more optimized. A lot previously duplicated code is now
8446 used as generic by both client and server.
8448 * Fixed key pair generation in clientutil.c
8450 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8452 * Added into lib/silccore/silcbufutil.[ch] new function;
8453 silc_buffer_realloc.
8455 * Moved generic packet sending/encryption functions to
8456 lib/silccore/silcpacket.[ch] from client and server. Some
8457 rewriting of the functions.
8459 * Moved all generic packet reception/decryption functions to
8460 lib/silccore/silcpacket.[ch] from client and server. The
8461 packet processing is now much cleaner in both client and server.
8462 These were major changes in both client and server.
8464 * Created many common functions in server to do packet sending.
8465 Previously code were duplicated a lot, this has been removed
8468 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8470 * Rewrote major parts of the ID cache system. Don't know
8471 whether it is better now or not but at least the API is more
8474 * Major rewrite on ID cache stuff on client because of the ID
8475 cache API changes. Added idlist.c to client.
8477 * Also major rewrite on ID cache stuff on server as well.
8478 Major rewrite of idlist.[ch]. SilcXXXList's are now named
8479 SilcXXXEntry's. We won't keep anymore idlist specific pointers
8480 in hand, instead they are all put into the ID cache system now.
8481 All server_idlist_* routines uses ID cache now instead of
8482 traversing its own lists (those lists does not exist anymore).
8483 SilcIDList though still exists. Also, SilcXXXEntry's are
8486 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8488 * Finally made the SKE implementation compliant to the protocol
8489 specification. All mp integers are now binary encoded as
8490 opposed being HEX encoded.
8492 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
8495 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
8496 functions: silc_[encode/decode]_pem. Also added function
8497 silc_encode_pem_file to PEM encode with newlines ('\n') for
8500 * SILC public keys are now encoded either PEM or binary. Same
8501 option is for private keys as well. By default private keys
8502 are binary encoded and public keys PEM encoded. Silly HEX
8503 encoding were removed.
8505 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
8506 function to create fingerprints.
8508 * Fixed a bug in SHA1; does not change the original data anymore.
8510 * Partly implemented INFO command on client and server side.
8511 Fixed CLEAR command. Changes to SERVER command; show current
8512 server(s) when giving command without arguments. Added
8513 VERSION command to client.
8515 * Added check to server that unregistered connections cannot
8516 execute commands (unless it is specificly allowed).
8518 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8520 * Fixed screen refresh.
8522 * Fixed channel joining bug from client. On some circumstances
8523 client tried to join to a channel it had already joined.
8525 * Added public key verification process into client's protocol.c.
8526 The client now verifies the public key from user and saves
8527 it into ~./silc/serverkeys/ directory.
8529 Added into: clientutil.[ch]: silc_client_verify_server_key.
8531 * Changed SKE protocol's silc_ske_initiator_finish function
8532 to accept callback function that verifies the received public
8533 key. Removed old silc_ske_verify_public_key function.
8535 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8537 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
8538 silc_pkcs_private_key[_data]_set.
8540 * Made the password and public authentication more cleaner in
8541 server's protocol.c.
8543 * Removed historic and obsolete protocol `channel_auth' from
8544 both client and server.
8546 * Removed wrong way of sending command status messages from
8547 server to client in server's command.c. The old way violated
8548 protocol specification.
8550 Changes to silccore/silccommand.[ch]: removed
8551 silc_command_encode_status_payload -> not needed anymore,
8552 changed silc_command_encode_payload_va to accept extra
8553 argument on variable argument list. The argument type must
8554 now be provided to the function. Also, added new function:
8555 silc_command_encode_reply_payload_va which is same as
8556 normal command_encode_payload_va except command status type
8557 is provided as extra argument.
8559 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8561 * Added ~./silc directory handling. The directory includes the
8562 public and private keys for the client.
8564 Added silc_client_check_silc_dir, silc_client_create_identifier
8565 and silc_client_load_keys.
8567 * Implemented SILC protocol compliant public key. Added public
8568 and private key saving to and loading from files.
8570 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
8571 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
8572 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
8573 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
8574 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
8576 Implemented: silc_pkcs_save_[public/private]_key[_data] and
8577 silc_pkcs_load_[public/private]_key.
8579 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8581 * Added silc_server_get_route (route.[ch]) to get connection
8582 data for the fastest route for given ID.
8584 * Implemented INVITE command on client and server. The command
8585 were re-defined in the SILC Protocol Specification and the
8586 implementation now complies with the specification.
8588 * Implemented PING command on client and server.
8590 * Implemented NAMES command on client and server. The server side
8591 supports currently only normal server not router server yet.
8592 Some changes to NAMES definition in SILC protocol specification.
8594 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8596 * Implemented LEAVE command on client and server.
8598 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
8599 again. This change was made to the protocol as well. Server
8600 should not violate the protocol specification anymore.
8602 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8604 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
8605 was tested. SOCKS4 was not but should work anyway.
