548 mask to the client. Updated protocol specs and the server.
549 Affected file is silcd/command.c.
551 * Added SILC session detachment/resuming support. It is possible
552 to detach by closing the network connection and then re-connect
553 and resume to the old client session. Added DETACHED user
554 mode that server will set for detached client. Added new
555 packet RESUME_CLIENT which is used to perform the resuming
556 process. Added DETACH command. Updated the protocol specs,
557 core library, client and server. Protocol TODO #22. Very
558 many affected files around the tree.
560 Wed Apr 10 16:32:01 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
562 * Changed the CMODE's mode mask argument to be optional. If
563 not provided then the command merely returns the current mode
564 mask to the client. Updated protocol specs and the server.
565 Affected file is silcd/command.c.
567 * Changed the Killer's Client ID in KILLED notify to be just
568 any ID payload since router server is allowed to kill as well.
569 Updated protocol specs, client libary and server. Affected
570 files are lib/silcclient/client_notify.c, silcd/packet_receive.c,
571 and irssi/src/silc/core/client_ops.c.
573 Tue Apr 9 17:15:42 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
575 * Added new user modes ANONYMOUS for special anonymous servers
576 that may set the mode for client, and BLOCK_PRIVMSG which
577 client may set to block incoming private messages unless the
578 Private Message Key flag is set (using private keys to protect
579 private messages). Updated protocol specs and code in client
580 and server and core library. Protocol TODO #23. Affected
581 files are lib/silccore/silcmode.h, silcd/server.[ch],
582 irssi/src/silc/core/client_ops.c, silcd/packet_receive.c,

586 may set to itself to tell server not send channel messages.
587 Other packets such as channel key packets are still sent.
588 Protocol TODO #23. Updated the protocol specs, client and
589 server. Affected files are lib/silccore/silcmode.h,
590 irssi/docs/help/in/cumode.in, lib/silcclient/command.c,
591 lib/silcutil/silcutil.c, silcd/command.c, and
594 Mon Apr 8 23:57:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
596 * Redefined the Status Payload to include now two 8 bit fields,
597 instead of one 16 bit field. This now makes it possible to
598 send list of errors. Updated the protocol specs and the code
599 in core library, client library and server. Protocol TODO #1.
600 Affected files are lib/silccore/silccommand.[ch],
601 lib/silcclient/command_reply.[ch], silcd/command.c,
602 silcd/command_reply.c and silcd/packet_receive.[ch].
604 Mon Apr 8 19:57:40 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
606 * Added config parse status SILC_CONFIG_EPRINTLINE, this status
607 must be handled by the application and should tell the application
608 that an error message was already printed, and it should print the
609 config coords (line, filename, ...). Affected files are
610 silcd/serverconfig.c, lib/silcutil/silcconfig.[ch].
612 * Added local macro SILC_SERVER_CONFIG_ALLOCTMP to make the
613 server config parsing code more readable.

628 lib/silccore/silcmode.h, irssi/src/silc/core/client_ops.c,
629 irssi/docs/help/in/umode.in and lib/silcclient/command.c.
631 Sun Apr 7 17:07:59 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
633 * Added STATS command to the protocol after all, to return
634 various statistical information about the network. It can
635 be used by clients to retrieve statistical information, and
636 servers may use it to to fetch cell and network wide
637 statistics from router. Updated the protocol specs and
638 implemented it to the server. Protocol TODO #16.
639 Affected files are lib/silccore/silccommand, silcd/command.[ch],
640 silcd/command_reply.[ch].
642 Sat Apr 6 17:08:58 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
644 * The LIST command reply in client libary now adds new channel
645 entry if the returned channel doesn't exist yet in cache,
646 and returns the channel entry to the application in the
647 command_reply client operation. Affected file is
648 lib/silcclient/command_reply.c.
650 * Changed the channel message payload's MAC generation to
651 include the IV in the MAC as well. This way all relevant
652 parts of the channel message payload are authenticated also
653 with the channel message MAC (and not only by packet MAC).
654 Causes incompatibility with 1.0 protocol. Protocol TODO #7.
655 Affected file is lib/silccore/silcchannel.c.
657 * Fixed the SKE to save the remote version, since the
658 silc_ske_parse_version mistakenly checked wrong version,
659 after it replaced the start payload. Affected files are
660 lib/silcske/silcske.[ch].
662 Fri Apr 5 16:03:03 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
664 * Splitted lib/silcutil/silcutil.h into silcstrutil.h for

673 UTF-8 encoded, defined that version string MUST be US-ASCII
674 encoded, defined that passphrases sent in connection
675 authentication protocol MUST be UTF-8 encoded. Implemented
676 these to the client and server. Defined also that other
677 passphrases sent in the protocol MUST be UTF-8 encoded.
678 Affected files are lib/silcske/silcske.c,
679 lib/silcclient/protocol.c, silcd/protocol.c,
680 silcd/serverconfig.c, and lib/silccore/silcauth.c.
682 * Changed the silc_client_close_connection interface to not
683 need the SilcSocketConnection which should not be visible
684 to application. Affected files are lib/silcclient/client.c
685 and lib/silcclient/silcclient.h.
687 * Rewrote the text for Private Message Key Payload in the
688 protocol specification. Protocol TODO #11.
690 Wed Apr 3 16:24:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
692 * Upgraded the protocol version to 1.1, updated protocol specs
695 * Added the nickname as new argument to NICK_CHANGE notify and
696 added it to protocol specs and implemented it to client and
697 server. Protocol TODO #3. Affected files are silcd/idlist.[ch],
698 silcd/command.c, silcd/packet_receive.c, packet_send.[ch], and
699 lib/silcclient/client_notify.c.

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

776 Affected file silcd/protocol.c.
778 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
780 * Some client implementations quit network by doing first LEAVE
781 and then immediately SIGNOFF (like Bombyx). We now do check
782 after a short time after LEAVE notify and check whether the
783 client is still valid after LEAVE, and if not we remove it from
784 cache. Affected file is lib/silcclient/client_notify.c.
786 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
788 * Merged version 1.1.4 of zlib. Even if it not currently in use,
789 it's good not to have security holes here.
791 * Fixed a negative refcount situtuation for the config context.
792 Affected file is silcd/serverconfig.c.
794 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
796 * ROBOdoc documented lib/silcutil/silcutil.h.
798 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
800 * Optimized even more the SilcPacketContext structure. Now
801 totally saved 16 bytes of memory per context after optimization.
802 Affected files are lib/silccore/silcpacket.[ch].
804 * Made strict checks for valid SILC IDs. Affected file is
805 lib/silccore/silcid.c.
807 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>

810 silc_hash_register, silc_hmac_register and silc_pkcs_register
811 to const. Affected files are lib/silccrypt/silccipher.[ch],
812 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
814 * Changed the silc_get_username and silc_get_real_name to
815 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
817 * Fixed the Irssi SILC Client to use the silc_get_username and
818 silc_get_real_name insted of glib routines since the glib
819 routines only corrupt stack. Fixes the Irssi SILC to work in
820 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
822 * Fixed the Irssi to not use g_get_home_dir since it crashes
823 or returns garbage on cygwin and corrupts stack. Added function
824 get_home_dir to Irssi routines. Affected files are
825 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
827 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
829 * Made some structure optimizations. SFTP memory FS MemFSEntry

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

981 * Added cross-reference support to the SILC Documentation
982 generator. All types across all HTML files are now cross-
983 referenced. Affected files util/robodoc/generator.c and
984 scripts/silcdoc/silcdoc.
986 * Added file lib/silcutil/silctypes.h to include all the
987 arithmetic type definitions and some macros. Removed
988 includes/bitmove.h and moved macros to silctypes.h.
990 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
992 * Merged bugfixes for Irssi SILC client from irssi.org CVS.

997 now returns the type of the ID to the sent pointer. Affected
998 file is lib/silccore/silcid.[ch].
1000 * Added check for CMODE_CHANGE notify type that mode change is
1001 allowed by the sender. Affected file silcd/packet_receive.c.
1003 * Added check for CUMODE_CHANGE notify type that mode change is
1004 allowed by the sender. Affected file silcd/packet_receive.c.
1005 Added the ID type as CUMODE_CHANGE notify type as argument
1006 to the `notify' client operation. Affected files are
1007 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
1009 * Added function silc_client_add_server to the client library.
1010 Added support for resolving also channel and server info when
1011 received unknown entity in notify packet. Affected files are
1012 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
1014 * Added function silc_command_get_status to return the command
1015 status from the command reply's argument payload. Affected files
1016 are lib/silccore/silccommand.[ch].
1018 * Added check for KICKED notify type that the kicking is
1019 allowed by the client. Affected file silcd/packet_receive.c.
1021 * Created function silc_get_input which can be used to get input
1022 (echo on or off) from user on command line. Affected files are
1023 lib/silcutil/silcutil.[ch].
1025 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1027 * Optimized silc_server_packet_relay_to_channel function.
1028 Added new function silc_channel_message_payload_encrypt which
1029 can be called directly if channel message payload needs to
1030 be encrypted and is already encoded (no need to call _encode
1031 function). Packet relaying is now done by router without any
1032 extra memory allocations. Affected files are
1033 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
1034 silcd/packet_send.c.

1047 SilcChannelClientEntry as well. Moved the function
1048 silc_server_check_cmode_rights to server_util.[ch].
1049 Affected files are silcd/server_util.[ch], silcd/command.c.
1051 * Added function silc_server_check_umode_rights to check whether
1052 changing client's user mode is allowed. Added check for
1053 UMODE_CHANGE notify type that the umode change is allowed
1054 by the client. Affected files are silcd/server_util.[ch],
1055 silcd/packet_receive.c and silcd/command.c.
1057 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1059 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
1060 ID length. It ignored that ID can be IPv6 based as well.
1061 Affected file lib/silccore/silcpacket.h.
1063 * Fixed the silc_id_id2str and silc_id_str2id to take the
1064 IPv6 address offset's into consideration. Affecte file is
1065 lib/silccore/silcid.c.
1067 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1069 * Fixed the internal Unix scheduler functions to check for
1070 NULL context they may receive. The affected file is
1071 lib/silcutil/unix/silcunixschedule.c.
1073 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
1075 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
1076 can specify different directory with --home command line
1077 parameter. Affected files irssi/src/silc/core/client_ops.c,
1080 * SILC-specific commands aren't now executed if the active server
1081 isn't of SILC-type, so there won't be problems with having
1082 IRC and SILC protocol support in same client. Affected files
1083 irssi/src/silc/core/silc-channels.c, silc-servers.c,
1086 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1088 * Improved the signal support in SILC Schedule. Added new
1089 function silc_schedule_signal_call which is used by application
1090 to mark a signal to be called. It is now safe to perform
1091 any kind of tasks in signal callbacks since it is guaranteed
1092 that the application specified signal callback is called
1093 after the signal is over. Affected files are
1094 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
1096 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1098 * Added `name' field to SilcChannelPrivateKey to represent
1099 application given name for the key. Moved also the context from
1100 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
1101 Added the `name' argument also to the function
1102 silc_client_add_channel_private_key.
1104 Added function silc_client_current_channel_private_key to set the
1105 current channel private key in use.
1107 Added "change" command to KEY command which can be used to change
1108 the current channel private key. Bound the command also to
1109 alt+K (Alt+Shift+k).
1111 Also affected files lib/silcclient/client_channel.c,
1112 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
1114 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1116 * Added silc_rng_get_byte_fast function in to the
1117 lib/silccrypt/silcrng.[ch].
1119 * Changed the interface of silc_packet_assemble and the
1120 silc_packet_send_prepare. If silc_packet_assmble is now
1121 called the application does not call silc_packet_send_prepare
1122 because the library will call it automatically. These
1123 interfaces now also return a reference to the outgoing buffer
1124 which includes the assembled packet, which the application can
1125 use to encrypt the packet.
1127 Affected files are lib/silccore/silcpacket.[ch],
1128 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
1129 silcd/packet_send.c, server_backup.c and packet_receive.c.
1131 * Fixed a packet sending bug on very high load, where outgoing
1132 packet queue wasn't handled correctly and packets got corrupted.
1133 Affected files are lib/silcutil/*/silc*sockconn.c,
1134 lib/silcclient/client.c and silcd/server.c.
1136 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1138 * Added macro SILC_PACKET_DATALEN which can be used during
1139 packet assembling to check whether the data to be added to
1140 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
1141 len is truncated until it fits it.
1143 Added checks for maximum length of channel message payload and
1144 private message payload also.
1146 Added checks for maximum packet length in server and in
1149 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
1150 lib/silcclient/client.c, lib/silccore/silcchannel.c and
1151 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
1152 lib/silcclient/client_prvmsg.c.
1154 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1156 * Added silc_server_packet_queue_purge call to the
1157 silc_server_disconnect_remote to assure that all data in the
1158 queue before disconnecting is sent to the network. Affected
1159 file silcd/server.c.
1161 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1163 * Added the deleting of server's own ID cache entry to the
1164 silc_server_free function. Free also everything else that
1165 has been allocated in silc_server_init. The affected file
1168 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1170 * Added functions silc_parse_version_string, silc_version_to_num,
1171 and silc_ske_parse_version to parse SILC protocol style version
1172 strings. Affected files lib/silcutil/silcutil.[ch] and
1173 lib/silcske/silcske.[ch].
1175 * Added new configuration params: version_protocol, version_software
1176 and version_software_vendor to specify what version the remote
1177 host must at least be to be able to connect to server. The vendor
1178 string can be regex matched too. Added new function
1179 silc_server_connection_allowed to check maximum number of allowed
1180 connections, and allowed versions for incoming connections.
1181 Affected files are silcd/server.c, server_util.[ch] and
1184 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1186 * Added preliminary support for signals in scheduler. The
1187 signals we care about are now blocked always when the scheduler
1188 is locked. This way we can synchronise the use of signal with
1189 scheduler. It is guaranteed that when signal occurs the scheduler
1190 is not locked, and thus new tasks can be safely added to the
1193 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
1194 to silc_schedule_internal_init and silc_schedule_internal_uninit.
1195 Added new platform specific routines
1196 silc_schedule_internal_signals_[un]block and
1197 silc_schedule_internal_signal_[un]register.
1199 Added new functions to SILC Schedule API:
1200 silc_schedule_signal_[un]register. Each signal that application
1201 is going to use should be registered to the scheduler.
1203 Affected files are lib/silcutil/silcschedule.[ch],
1204 lib/silcutil/*/silc*schedule.c.
1206 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1208 * Check for unauthenticated client and server in the
1209 silc_server_new_client and silc_server_new_server functions.
1210 Affected file silcd/packet_receive.c.
1212 * Added function silc_string_is_ascii to check whether given
1213 string is 7-bit ASCII string. Affected files are
1214 lib/silcutil/silcutil.[ch].
1216 * Added function silc_id_is_valid_server_id into the
1217 silcd/serverid.c and added checking for valid Server ID's in
1218 silc_server_new_server. The Server ID must always be based
1219 on the server's public IP address.
1221 * Added logging of DISCONNECT packet message in the server.
1222 Affected file silcd/server.c.
1224 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1226 * Changed all library interfaces that use Global RNG to also
1227 accept SilcRng as argument. Affected files are
1228 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
1229 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
1230 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
1231 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
1232 lib/silccrypt/rsa.c.
1234 * Added function silc_pkcs_generate_key to the
1235 lib/silccrypt/silcpkcs.[ch] for applications so that they
1236 don't need to do pkcs->pkcs->init calls anymore.
1238 * Remove SilcSocketConnection from the SFTP API since it really
1239 wasn't needed there. The application has the information
1240 saved in its contexts anyway and the SFTP layer doesn't need
1241 know about it. Affected files lib/silcsft/silcsftp.h and
1242 lib/silcsftp/sftp_[server/client].c.
1244 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
1245 The SilcSimContext is not SilcSim.
1247 * Fixed possible buffer overflows in silc_id_render in the
1248 lib/silcutil/silcutil.c.
1250 * On EPOC the global crypto module lists are not used at all
1251 in the crypto library. Added support for using the constant
1252 algorithm list on EPOC. Affected files are
1253 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
1256 * Fixed the handling of third parameter of KICKED notify, since
1257 it was mistakenly updated to SILC Protocol 1.0 even though it
1258 is to be included in 1.1. Since it is not in 1.0 it is not
1259 mandatory, and this fix now handles it only if it is provided,
1260 and it is not error if it is not provided. Affected file
1261 lib/silcclient/client_notify.c.
1263 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1265 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
1266 client. Affected file irssi/src/silc/core/client_ops.c.
1268 * Merged with Irssi 0.8.4 from irssi.org CVS.
1270 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1272 * Check for valid socket connection in client entries before
1273 sending any messages. Fixes a crash, but doesn't fix some
1274 other underlaying bug that is lurking there. Affected
1275 file silcd/packet_send.c.
1277 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
1279 * $usermode, $cumode and $cumode_space expandos shouldn't do
1280 anything with non-SILC server records. Affected file
1281 irssi/src/silc/core/silc-expandos.c
1283 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1285 * Fixed the silc_net_check_[host/local]_by_sock to support
1286 IPv6 bound sockets as well. Now they can return IPv6 addresses
1287 as well. Affected file lib/silcutil/silcnet.c.
1289 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
1290 Affected lib/silcutil/unix/silcunixnet.c.
1292 * Fixed ID rendering (at least on some platforms, not NetBSD)
1293 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
1295 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1297 * Added silc_hash_public_key and silc_hash_public_key_compare
1298 functions to be used with SilcHashTable. They can be used to
1299 hash public keys and compare public keys in hash table. Affected
1300 file lib/silcutil/silcutil.[ch].
1302 * Added support for specifying multiple public keys for Client
1303 connection section in server configuration file. This makes it
1304 possible to accept multiple public keys from same host, or to
1305 make a section that accepts any incoming host, and have the
1306 accepted public keys listed in the section.
1308 Added functions silc_sever_[find/get]_public_key, added the
1309 support for this actually to all connection sections but only
1310 the Client section is currently allowed to specify multiple
1313 Affected files are silcd/server.c, server_internal.h,
1314 command.c, protocol.c, server_util.[ch], packet_receive.c.
1316 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1318 * Merged Irssi 0.8.2 from irssi.org CVS.
1320 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1322 * If silc_debug is TRUE, also output standard logging messages
1323 to stderr with the debug output.
1325 Made silc_log_reset_all() flushing all channels before returning.
1326 Also fixed some documentation typos.
1328 Affected files are lib/silcutil/silclog.[ch].
1330 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1332 * Fixed the server to check correctly the amount of connections
1333 from single host, by checking also the type of the connection.
1334 Fixed also the comparison of number of connections and number
1335 of allowed connections. Affected files are silcd/server.c,
1338 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1340 * Fixed the USERS command reply to save the user's mode on the
1341 channel as well. Fixed JOIN command reply to check whether a
1342 client is on channel already and not join it twice. Affected
1343 file lib/silcclient/command_reply.c.
1345 * Added new file silc-expandos.c into irssi/silc/core/ to return
1346 various stuff for various signal for the statusbar etc. updating.
1347 Now Irssi SILC client prints channel user modes etc. on the
1350 * The user mode (like server/router operator changes) is now shown
1351 on the Irssi SILC client's statusbar. The affected files are
1352 irssi/src/silc/core/client_ops.c, silc-expandos.c.
1354 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1356 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
1357 to SILC_SCHEDULE_[UN]LOCK macros.
1359 * Added more error printing to logs in server code. Affected
1360 files silcd/server.c and silcd/protocol.c.
1362 * Fixed -S option parsing in Irssi SILC Client. Affected file
1363 irssi/src/silc/core/silc-core.c.
1365 * Added silc_buffer_alloc_size function. Affected file is
1366 lib/silcutil/silcbuffer.h.
1368 Tue Mar 5 14:37:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1370 * Changed all silc_[hash|hmac|cipher|pkcs]_default tables to
1371 constants. Affected files in
1372 lib/silccrypt/silcpkcs.[ch], silchash.[ch], silchmac.[ch] and
1375 * Changed the internal SFTP Memory FS table to const. Affected
1376 file lib/silcsftp/sftp_fs_memory.c.
1378 Sun Mar 3 18:37:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1380 * Fixed the buffer formatting and unformatting routines to
1381 check the size of 64 bits types with sizeof(). Affected
1382 file is lib/silcutil/silcbuffmt.c.
1384 Mon Feb 25 17:19:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1386 * Removed 0.6.x backwards support.
1388 Sun Feb 24 12:53:25 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1390 * Changed all integer type names:
1391 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
1392 to avoid collisions with other libraries using same type names
1395 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1397 * Added `prefer_ipv6' argument to the functions
1398 silc_net_gethostbyname[_async]. If it is TRUE it will return
1399 IPv6 address over IPv4. If FALSE IPv4 address is returned
1400 even if IPv6 address was found. Affected files
1401 lib/silcutil/silcnet.[ch].
1403 * Added support silc_net_create_connection[_async] to fallback
1404 to IPv4 address if IPv6 address could not be used (like if
1405 it doesn't work on a specific system). Affected file in
1406 lib/silcutil/unix/silcunixnet.c.
1408 Sat Feb 23 15:20:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1410 * Added silc_schedule_reinit function to do the enlarging
1411 of the max tasks handling capabilities of the scheduler.
1412 Affected files lib/silcutil/silcschedule.[ch].
1414 Wed Feb 20 20:41:01 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1416 * Added automatic extern "C" { ... } for C++ compilers so the
1417 application does not need to define them. Affected file
1418 includes/silcincludes.h.
1420 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
1421 old name went against naming convention. Applications now
1422 include "silcclient.h" instead of "clientlibincludes.h".
1423 Removed includes/clientlibincludes.h, it is redundant now.
1425 * Renamed includes/version.h to silcversion.h.
1427 * Added really preliminary support for OS/2 into the util
1428 library. Only thread & mutex API is implemented, others
1429 are still to be implemented. Created the lib/silcutil/os2/
1430 directory. Created also file includes/silcos2.h.
1432 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1434 * Added preliminary BeOS support into the util library.
1435 Created lib/silcutil/beos/, and implemented all the needed
1436 functions to support SILC on BeOS. Created also file
1437 includes/silcbeos.h.
1439 Mon Feb 18 15:49:22 EET 2002 Timo Sirainen <tss@iki.fi>
1441 * Added proper initializations to silc's irssi code, so it's
1442 now possible to load it as module. Affected files
1443 irssi/src/silc/core/silc-core.c,
1444 fe-common/silc/fe-common-silc-core.[ch] and fe-text/silc.c
1446 Sun Feb 17 19:02:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1448 * Merged latest Irssi (0.8.1) from the irssi.org's CVS into
1451 * Fixed the silcdoc document generator to correct generate
1452 docs from all kinds of filenames. Affected files are
1453 util/robodoc/Source/generator.c, scripts/silcdoc/silcdoc
1455 * ROBOdoc documented lib/silcutil/silcmemory.h.
1456 Added also new function silc_memdup.
1458 * Removed lib/silcutil/silcbufutil.h and moved those routines
1459 to the lib/silcutil/silcbuffer.h.
1461 Sun Feb 17 15:52:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1463 * Added `user_count' to the SilcChannelEntry which now tells the
1464 number of users on the channel. The user count is now saved
1465 in normal server of global channels as well. Affected files
1466 silcd/server.c, idlist.h, packet_receive.c and command.c.
1468 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
1469 include file utility functions.
1471 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
1472 instead of calling directly OS routines.
1474 * Fixed NICK change printing in Irssi SILC Client. Fixed
1475 KICKED notify printing in Irssi SILC Client. Affected file
1476 irssi/src/silc/core/client_ops.c.
1478 * Fixed a NICK change bug in client library, to not recreate the
1479 client_entry->channels hash table everytime nick is changed.
1480 Affected file lib/silcclient/client.c.
1482 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1484 * ROBOdoc documented the lib/silcske/silcske.h, and improved
1485 the SKE interface a bit.
1487 * Fixed padding problem in PKCS#1. The padding was not actually
1488 random since the random number generator was used incorrectly.
1489 This security bug affects only when encrypting with PKCS#1, and
1490 it is not currently used at all in SILC. SILC only use signing
1491 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
1493 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1495 * Rewrote the notify handling in Irssi SILC client to not call
1496 the events as signals. Fixes problems with Perl support.
1497 Affected files irssi/src/silc/core/client_ops.c, silc-channels.c.
1499 * Send the auto-nicking NICK command in client library with
1500 little timeout after connecting. The affected file is
1501 lib/silcclient/client.c.
1503 * Added following new config file settings:
1504 channel_rekey_secs, key_exchange_rekey, key_exchange_pfs,
1505 key_exchange_timeout, conn_auth_timeout, connections_max,
1508 Implemented all the new config settings handling in the server.
1510 Optimized the use of SKE Mutual flag usage. Use it only
1511 if connection authentication protocol is not based in public
1514 Renamed all SilcServerConfigSection* to SilcServerConfig*
1515 to have a bit shorter names.
1517 Affected files silcd/serverconfig.[ch], server.[ch], and
1520 Sat Feb 16 02:46:43 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1522 * Cleaned up the listening sockets code, preparing for the rehash
1523 support. Affected file is silcd/server.c.
1525 * Fixed some output messages. Affected files are silcd/silcd.c,
1528 Fri Feb 15 19:10:20 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1530 * Create lib/doc/silcrng_intro.html document as introduction
1531 to SILC RNG. ROBOdoc documented lib/silccrypt/silcrng.h.
1533 Fri Feb 15 13:23:03 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1535 * Fixes to the silcd config template. Affected file is
1536 doc/example_silcd.conf.in.
1538 * Removed type casts from silc_calloc(), conforming to the
1539 CodingStyle. Affected file is lib/silcutil/silcconfig.c.
1541 * Removed param_name member from client, server, and router
1542 section structs, now identifying the param directly.
1544 Added CONFIG_FREE_AUTH macro in config file parsing.
1546 Affected files are silcd/serverconfig.[ch].

1550 * Fixed command line parameter handling. All SILC initialization
1551 is now done in silc_core_init() which also fixes autoconnecting
1554 Affected files irssi/src/silc/core/silc-core.c,
1555 irssi/src/fe-text/silc.c.
1557 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1559 * Added new configuration options and blocks:
1560 keepalive_secs, reconnect_count, reconnect_interval,
1561 reconnect_interval_max, reconnect_keep_trying and
1562 require_reverser_lookup. Added ConnectionParam block, and
1563 implemented the connection parameters when connecting as
1564 initiator and when accepting connections as responder.
1566 Added CONFIG_IS_DOUBLE macro in config file parsing, to check
1567 whether given configuration value has been given already.
1569 Affected files silcd/serverconfig.[c], server.[c].
1571 * Splitted the doc/example_silcd.conf.in. Separated the crypto
1572 algorithm parts and created new file silcalgs.conf, that
1573 is now included from the example_silcd.conf.in.
1575 * Optimized the silc_server_connect_to_router_second to take
1576 the connection configuration object from the SilcServerConnection
1577 object instead of finding it during the connecting phase.
1578 Added the configuration object to SilcServerConnection struct.
1579 Affected files silcd/server_internal.h, server.c.
1581 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1583 * Add the client on channel after it was resolved at the
1584 channel message receiving, and it was not already on the
1585 channel. Affected file lib/silcclient/client_channel.c.
1587 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1596 Affected file silcd/serverconfig.[ch].
1598 * Removed doc/example_silc.conf.in since it is redundant.
1599 The make install will now install irssi/silc.conf file.
1601 * Added new Passphrase and Publickey authentication methods to
1602 config file, allowing both public key and passphrase based
1603 authentication to be set at the same time.
1605 Added `prefer_passphrase_auth' setting in config file which
1606 can be used to set to prefer passwd auth if both passwd and
1607 public key is set. If not set, public key is preferred.
1608 This has effect only when being initiator (responder will try
1611 Added support for authentication with passphrase and public key
1612 at the same time. The passphrase is tried first always since
1613 it is faster to check.
1615 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
1617 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1619 * Merged the new SILC Config library, with the server parsing
1620 support. Read the header file silcconfig.h or the toolkit
1621 documentation for the news. Affected files are

1643 * Allow zero length channel messages inside the Channel Message
1644 Payload. Affected file lib/silccore/silcchannel.c.
1646 * Fixed scripts/silcdoc/silcdoc to support all kinds of filenames
1647 as header filenames.
1649 * Removed lib/silcclient/README and created HTML file
1650 lib/silcclient/silcclient_using.html, which is now included
1651 as part of Toolkit documentation.
1653 Thu Feb 7 10:12:25 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1655 * Fixed CUMODE_CHANGE notify handling to change the mode of
1656 correct client. Affected file lib/silcclient/client_notify.c.

1663 * Fixed the file transfer's key agreement payload to include
1664 zero port also if the hostname is NULL because it could not
1667 Call file transfer monitor callback now also if error occurs
1668 during key agreement protocol.
1670 Changed the silc_client_file_send interface to return the
1671 SilcClientFileError instead of session id. The session ID
1672 is returned into pointer provided as argument.
1674 Check that the file exists locally before sending the
1675 file transfer request at all.
1677 Affected file lib/silcclient/client_ftp.c, silcapi.h.
1679 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer
1680 error than can occur while key agreement protocol. Affected
1681 file lib/silcclient/silcapi.h.

1687 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
1688 SILC_LOG_WARNING to give out Warning and not Error. Affected
1689 file lib/silcutil/silclog.c.
1691 * Fixed the channel message payload decryption in the function
1692 silc_channel_message_payload_decrypt to not modify the original
1693 buffer before it is verified that the message decrypted
1694 correctly. Otherwise, next time it is called with correct
1695 channel key it won't encrypt since the payload is corrupted.
1696 Affected file lib/silccore/silcchannel.c.
1698 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1708 Fri Feb 1 22:33:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1710 * Fixed a bug in hash table internal routine for traversing
1711 the table with foreach callback. The current entry may
1712 become invalid in the callback but it was referenced after
1713 the callback returned.
1715 Do not allow auto rehashing of hash table during the
1716 silc_hash_table_foreach operation, for same reasons as it is
1717 not allowed for SilcHashTableList. Affected files are
1718 lib/silcutil/silchashtable.[ch].
1720 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1722 * Defined DLLAPI into silcincludes.h and silcwin32.h for
1723 Win32 DLL. extern's in header files are now declared with
1726 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1728 * Fixed private message handling. It used some old code that
1729 caused the client to crash. Affecte file is
1730 lib/silcclient/client_prvmsg.c.
1732 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1734 * Added function silc_client_add_channel,
1735 silc_client_replace_channel_id, and removed functions
1736 silc_client_new_channel_id and silc_idlist_get_channel_by_id
1737 from client library.
1739 * Added cross reference of the joined channels to the
1740 SilcClientEntry, and changed the SilcChannelEntry's
1741 users list to SilcHashTable. The affected files are
1742 lib/silcclient/idlist.[ch].
1744 * Fixed a bug in hash table tarversing. While the hash table
1745 is traversed with SilcHashTableList the table must not be
1746 rehashed. It is now guaranteed that auto rehashable tables
1747 are not rehashed while tarversing the list. Also defined that
1748 silc_hash_table_rehash must not be called while tarversing
1749 the table. Added function silc_hash_table_list_reset that must
1750 be called after the tarversing is over. The affected files are
1751 lib/silcutil/silchashtable.[ch].
1753 * Changed all hash table traversing to call the new
1754 silc_hash_table_list_reset in server and in client library.
1756 * Added function silc_client_on_channel to return the
1757 SilcChannelUser entry if the specified client entry is joined
1758 on the specified channel. This is exported to application as
1759 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
1761 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1763 * Fixed founder regaining problem with JOIN command on normal
1764 server. The notify for mode change must be sent always and
1765 not only if !cmd->pending. Affected file silcd/command.c.
1767 * Fixed the WHOWAS command's reply sending to support the
1768 lists correctly. Affected file silcd/command.c.
1770 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1772 * When sending JOIN command to router for processing the
1773 sender's old command identifier was not saved back to the
1774 sender's command context, fixed now. The affected file is
1777 * Create the key in JOIN command of the router did not return
1778 the channel key, added check for this. Affected file is
1781 * Fixed a channel ID update bug in JOIN command reply. Do
1782 not directly upgrade the ID but call the function
1783 silc_idlist_replace_channel_id if the ID was changed.
1784 Affected file silcd/command_reply.c.
1786 * Fixed memory leaks from command calling if it would fail.
1787 Affected file silcd/command.c.
1789 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1791 * Applied patches from cras:
1793 Memory leak fixes around libaries, irssi window resize fix,
1794 new silclist.h and silcdlist.h, all extern inline changed to
1797 * Removed dotconf from lib/dotconf, not needed anymore.
1799 * Removed TRQ from lib/trq, not needed anymore.
1801 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
1802 with server connections. Later this will be configurable
1803 in config file after new config file is done. Affected file
1806 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1808 * Fixed a crash in server related to channel announcements.
1809 Affected file silcd/server.c.
1811 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1813 * Fixed memory leaks in silc_server_create_new_channel*
1814 functions. Affected file silcd/server.c.
1816 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
1817 which ID was changed. This way the router will send the
1818 user list for the channel again, and server won't be in
1819 desync in some rare circumstances. Affected file is
1820 silcd/packet_receive.c.
1822 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1824 * Check for NULL socket pointer in the function
1825 silc_server_packet_send_to_channel_real. Affected file
1826 silcd/packet_send.c.

1833 * Fixed some header addition to Toolkit distribution in
1834 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
1836 * Added lib/silcclient/client_ops_example.h as an template
1837 file for application programmers to quickly start using
1838 the SilcClientOperation functions in their application.
1839 Updated the lib/silcclient/README as well to tell about this
1840 nice file made available.
1842 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1844 * Call silc_server_remove_from_channels when removing client
1845 entry when NO_SUCH_CLIENT_ID was received. Affected file
1846 is silcd/command_reply.c.
1848 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1850 * Added server & router operator statistics updating. Affected
1851 file silcd/packet_receive.c and silcd/command.c.
1853 * Fixed the SERVER_SIGNOFF notify handling on normal server
1854 not to save the history information for clients. Same was
1855 fixed earlier in remove_clients_by_server function, but not
1856 here. Affected file silcd/packet_receive.c.
1858 * Raised the default connection-retry count from 4 to 7 in
1859 server. Affected file silcd/server.h.
1861 * Cancel any possible reconnect timeouts when we start the
1862 key exchange. Affected file silcd/server.c.
1864 * Do not reconnect on connection failure when SCONNECT was
1865 given. Affected files silcd/server.[ch].
1867 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1869 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
1871 * Fixed the NICK command to always give the unformatted
1872 nickname to the one giving the NICK command. If unformatted
1873 nickname is cached already it will be formatted and the
1874 local entry will always get the unformatted nickname.
1875 Affected file lib/silcclient/idlist.c.
1877 * Fixed some double frees from client library commands.
1878 Affected file is lib/silcclient/command.c.
1880 * Fixed CUMODE command in server to assure that no one can
1881 change founder's mode than the founder itself, there was a
1882 little bug. Affected file silcd/command.c.
1884 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1886 * Removed the SilcClientCommandDestructor from the client
1887 libary, it is not needed anymore. Affected files are
1888 lib/silcclient/silcapi.h, command[_reply].[ch],
1889 client_notify, idlist.c.
1891 * Fixed GETKEY command to first resolve client, and then
1892 resolve the server only if the client was not found, instead
1893 of resolving both at the same time. Affected file is
1894 lib/silcclient/command.c.
1896 * Added silc_client_start_key_exchange_cb and lookup the
1897 remote hostname and IP address before starting the key
1898 exchange with server. The affected file is
1899 lib/silcclient/client.c.
1901 * The server's public key is now saved using the IP address
1902 of the server and not the servername for the filename.
1903 The hostname public key filename is checked as an fall back
1904 method if the IP address based filename is not found.
1906 Fixed the GETKEY command to save the fetched server key
1907 in correct filename.
1909 Print the remote server's hostname now when new key is
1910 received during connection process. Affected file is
1911 irssi/src/silc/core/client_ops.c.
1913 * Return always our own public key to the client if it asks
1914 for it with GETKEY command. Affected file silcd/command.c.
1916 * Removed the use_auto_addr variable from default config
1917 file since it was in wrong section. Affected file is
1920 * Fixed TOPIC_CHANGE notification to not route it when it
1921 was sent using silc_server_send_notify_to_channel function.
1922 Affected file silcd/command.c.
1924 * Fixed silc_server_send_notify_kicked to send the kicker's
1925 Client ID also, it was missing. Affected files are
1926 silcd/command.c, silcd/packet_send.[ch].
1928 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1930 * Do not save client history information in SERVER_SIGNOFF.
1931 Fixes the bug in normal server that it does not detect
1932 the client becoming valid after the server becomes back
1933 online. Affected file silcd/server_util.c.
1935 * Added `sock_error' field into the SilcSocketConnection
1936 context. When error occurs during socket operation (read
1937 or write) the error is saved. Added also new function
1938 silc_socket_get_error to return human readable socket error
1939 message. Affected files are lib/silcutil/silcsockconn.[ch],
1940 lib/silcutil/unix/silcunixsockconn.c, and
1941 lib/silcutil/win32/silcwin32sockconn.c.
1943 * The server now prints the socket error message in the
1944 signoff for client. Affected file silcd/server.c.
1946 * Fixed the `created' channel information sending from router
1947 to server in JOIN command. Checks now whether the channel
1948 really was created or not and set it according that.
1950 Fixed the JOIN command to use the client entry's current
1951 ID during the joining procedure instead of the one it sent
1952 in the command (it is checked though), since it can change
1953 between the packet processing and command processing, and
1954 would just case unnecessary pain in the client end. Affected
1955 file silcd/command.c.
1957 * Fixed a channel key payload sending to use correct channel
1958 ID when the server was forced to change the channel's ID by
1959 router. Router sent the key payload with the old Channel ID.
1960 Affected file silcd/packet_receive.c.
1962 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1964 * Call silc_server_save_channel_key only if the key payload
1965 was provided in the JOIN command's command reply. Affected
1966 file silcd/command_reply.c.
1968 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1970 * Fixed silc_mp_sizeinbase to return the value correctly with
1971 MPI. Affected file lib/silcmath/mp_mpi.c.
1973 * Fixed the stop_server signal to correctly stop the scheduler
1974 and gracefully stop the server when SIGTERM or SIGINT signals
1975 are received. Affected file silcd/silcd.c.
1977 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1979 * Simple handling of TERM and HUP signals. Also added some log
1980 flushing call around. Affected file is
1983 * Fixed small bugs in silclog.c. Now buffering output will take
1984 effect after 10 seconds since startup: This will ensure that
1985 no important startup messages are lost. Also output redirection
1986 will preserve original format ([Date] [Type] message).
1987 Affected file is lib/silcutil/silclog.c.
1989 * Added two options to the config file, in the logging section:
1990 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1991 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1993 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1995 * Do not print the warning about log files not being initialized
1996 more than once to avoid excess logging. Affected file is
1997 lib/silcutil/silclog.c.
1999 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
2000 the SIM copying in make install in Makefile.am.pre.
2002 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2004 * Rewritten silclog APIs. Globally interesting changes follows:
2005 silc_log_set_files() changed to silc_log_set_file().
2006 silc_log_set_callbacks() changed to silc_log_set_callback().
2007 ROBOdoc documented silclog header file.
2008 SilcLogCb now returns bool to wether inihibit the default
2009 handler or not (to keep the old behaviour return always TRUE).
2010 The new APIs should also fix the problem of the
2011 silcd_error.log file that was written in the current directory.
2014 Log files streams will remain opened after silc_log_set_file()
2015 call, means less CPU usage notably on high traffic servers.
2016 File streams are now full buffered, and flushed to the disk
2017 every 5 minutes, lesses HD activity and CPU usage.
2018 Messages can be redirected, allowing admins to configure
2019 one single logfile for all server messages.
2020 the silc_log_quick global variable to activate fast-logging.
2021 Affected files lib/silcutil/silclog.[ch]
2023 * Changed some code to conform new silclog APIs. Affected
2024 files are doc/example_silcd.conf.in, silcd/server.c
2025 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
2028 * Fixed a memory leak that could occur in some situations.
2029 Affected file silcd/serverconfig.c.
2031 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2033 * Added the silc_client_del_client to remove the client from
2034 all channels as well. Affected file lib/silcclient/idlist.c.
2036 * Fixed the client library to correctly remove the client
2037 from all channels when the client entry is being destroyed.
2038 Affected file lib/silcclient/client_notify.c, command.c.
2040 * Added auto-nicking support to the client library. If the
2041 applicatio now sets client->nickname it will be sent to the
2042 server after connecting by the library. This way for example
2043 SILCNICK (or IRCNICK) environment variables will have effect
2044 and always change the nickname automatically to whatever
2045 it is wanted. Affected file lib/silcclient/client.[ch].
2047 * Renamed silc_server_command_bad_chars to the
2048 silc_server_name_bad_chars and moved it to the
2049 silcd/server_util.[ch]. Added also new function
2050 silc_server_name_modify_bad to return nickname that
2051 includes bad characters as new nickname without those
2052 bad characters. This check and modify is now used in
2053 silc_server_new_client when the username is initially set
2054 as nickname, so it must be checked to be valid nickname.
2055 Affected file silcd/packet_receive.c.
2057 * The nickname length is now taken from the packet for real
2058 and not trusted to strlen() since it clearly can return
2059 wrong length for nickname including bad characters. This
2060 also applies to channel names. Affected file silcd/command.c.
2062 * Removed the lib/silcsilm/modules directory. Modules are now
2063 compiled into the lib/silcsim. Fixed the copying of the
2064 modules to follow symbolic links in Makefile.am.pre.
2066 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2068 * Fixed silc_string_regexify list creation. Fixes bugs with
2069 BAN and INVITE commands in server. The affected file is
2070 lib/silcutil/unix/silcunixutil.c.
2072 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2074 * Removed the command destructor entirely from the server's
2075 command and command reply routines. It is not needed, and
2076 its usage was buggy and caused crashes. Affected files are
2077 silcd/command[_reply].[ch].
2079 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2081 * Cancel protocol and NULL sock->protocol if timeout
2082 occurred during protocol. Affected file silcd/server.c.
2084 * Cancel protocol timeouts always before calling the final
2085 callback, to assure that after final callback is called
2086 no other state will be called for the protocol anymore.
2087 Affected file silcd/protocol.c.
2089 * Print error log if incoming connection configuration could
2090 not be found. Affected file silcd/server.c.
2092 * Fixed JOIN command to correctly save the founder mode
2093 to the client on normal SILC server, when the channel
2094 was created by the router. Affected file silcd/command.c.
2096 * Fixed LIST command (hopefully) to send correct reply
2097 packets. Affected file silcd/command.c.
2099 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2101 * The silc_packet_receive_process now returns FALSE if the
2102 read data was invalid packet, and TRUE if it was ok.
2104 The server now checks that if unauthenticated connection
2105 sends data and its processing fails the server will close
2106 the connection since it could be a malicious flooder.
2108 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
2110 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2112 * Make sure the warning about error opening a log file is
2113 printed only once and not everytime it fails (produces
2114 too much useless log). Affected file lib/silcutil/silclog.c.
2116 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2118 * Made the silc_server_daemonise() function more readable.
2119 Affected file silcd/server.c.
2121 * Pid file is now optional, the user may comment it out from
2122 the config file. Removed define SILC_SERVER_PID_FILE, we
2123 don't need a default any longer. Affected file
2124 configure.in.pre, lib/Makefile.am.pre.
2126 * Make some use of the pid file. The server now dies at startup
2127 if it detects a valid pid file on his path. The server would
2128 die anyway in this circumstance, because of the bind() failure.
2129 Affected file silcd/silcd.c.
2131 * No longer compiling lib/dotconf.
2133 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2135 * Fixed JOIN command parsing not to crash. Affected file
2136 lib/silcclient/command.c.
2138 * Fied the NICK_CHANGE notify to add the new client entry
2139 even it is resolved. This removes an <[unknown]> nick
2140 thingy bug in the client. Affected file is
2141 lib/silcclient/client_notify.c.
2143 * Do not try to allocate 0 bytes (efence does not like it)
2144 in lib/silccore/silccomand.c when encoding payload.
2146 * Do not take IRCNICK as nickname in Irssi SILC client since
2147 it is not possible to set nickname before hand connecting
2148 the server (TODO has an entry about adding auto-nicking
2151 * Changed the silc_server_command_pending to check whether
2152 there already exists an pending entry with the specified
2153 command, command identifier and pending callback. This is
2154 to fix IDENTIFY and WHOIS related crashes that may register
2155 multiple pending commands with same identifier. Affected
2156 file silcd/command.c.
2158 * Fixed the server to reconnect to the router even if it
2159 was already reconnecting and EOF was received. This to
2160 fix a possibility that the server wouldn't ever try to
2161 auto-reconnect to the router. Affected file silcd/server.c.
2163 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2165 * Fixed the server's password authentication to use the
2166 length of the locally saved password, and not the one
2167 sent in the packet. Affected file silcd/protocol.c.
2169 * Fixed same password authentication problem in the
2170 Authentication Payload handling routines in
2171 lib/silccore/silcauth.c.
2173 * Yet another password authentication problem fixed with
2174 channel password handling in silcd/command.c.
2176 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2178 * If first character of string in silc_parse_userfqdn is '@'
2179 then do not parse it. Affected file is
2180 lib/silcutil/silcutil.c.
2182 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2184 * Fixed minor bug in IDENTIFY command reply sending, which
2185 caused various weird problems during JOIN when it was
2186 resolving names for users. Affected file silcd/command.c.
2188 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2190 * Fixed the IDENTIFY command reply sending to chech better valid
2191 clients. It was possible to send incomplete list of replies.
2192 Affected file silcd/command.c.
2194 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2196 * Added silc_client_command[s]_[un]register functions now to
2197 dynamically register the commands in client library. Removed
2198 the static table of commands. This allows the client library
2199 to call commands without causing the application to know about
2200 what commands library has called.
2202 Removed the INFO command reply kludge to detect when the command
2203 was called by library. Now library use its own command reply
2204 function for INFO command.
2206 Added function silc_client_command_call to call a command.
2207 Application can use it to call command, not access the structure
2210 Now all commands that are sent by the client library (not
2211 explicitly sent by application) use own command reply functions.
2213 Affected files around lib/silcclient/ and in
2214 irssi/src/silc/core/.
2216 * Fixed the WHOIS command reply sending to chech better valid
2217 clients. It was possible to send incomplete list of replies.
2219 Fixed the WHOIS and IDENTIFY to send the request to router
2220 if normal server did not do it and did not find any results.
2222 Affected file silcd/command.c.
2224 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2226 * Moved the internal data from SilcClient context into its
2227 own file, not accesible to application. Affected files
2228 lib/silcclient/client.h and lib/silcclient/client_internal.h,
2229 and other files in client library.
2231 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2233 * Added doc/examples installation target in Makefile.am.pre.
2236 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2238 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
2239 commands the found client entry will be removed from the
2240 cache, after notifying application about the error. Affected
2241 file lib/silcclient/command_reply.c.
2243 * Changed the /MSG to check for exact nickname user gave, and
2244 not let `nick' match `nick@host' if it is only one found. Now,
2245 user must type the exact nickname (like nick@host2) even if
2246 there are no more than one same nicks found. This is to avoid
2247 a possibility of sending nickname to wrong nickname since
2248 `nick' could match `nick@host'. Affected file is
2249 irssi/src/core/silc-servers.c.
2251 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2253 * Do not print "you are now server operator" or similar when
2254 giving /away command. Affected files are
2255 irssi/src/silc/core/client_ops.c, silc-servers.h.
2257 * Made the silc_server_command_pending_error_check to send
2258 the same command reply payload it received back to the
2259 original sender of the command. This way all arguments
2260 that was received by the server will be received by the
2261 client too. Affected file silcd/command.c.
2263 * Added the silc_idcache_add to return the created cache entry
2264 to a pointer. Affected file lib/silccore/silcidcache.[ch].
2266 * Add global clients to expire if they are not on any channel.
2267 This is because normal server will never know if they signoff
2268 if they are not on any channel. The cache expiry will take
2269 case of these entries. This is done by normal servers only.
2270 The affected files are silcd/command_reply.c,
2271 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
2273 * If server receives invalid ID notification for WHOIS or
2274 IDENTIFY and the ID exists in the lists, it is removed.
2275 Affected file silcd/command_reply.c.
2277 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
2278 in client then client entry that it matches is searched and
2279 the nickname is printed on the screen for user. Affected
2280 file irssi/src/silc/core/client_ops.c.
2282 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2284 * Use cache entry expire time in the LIST command reply to
2285 purge old entries from the cache after the LIST command
2286 reply has been received. This way we don't have non-existent
2287 entries in the cache for too long. Affected file is
2288 silcd/command_reply.c.
2290 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2292 * If we are normal server, and we've not resolved client info
2293 in WHOIS or IDENTIFY from router, and it is global client,
2294 we'll check whether it is on some channel. If it is not
2295 then we cannot be sure about its validity and will resolve it
2296 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
2297 file silcd/command.c.
2299 * Search channel by name (if possible) rather than by ID
2300 in IDENTIFY command's command reply. Affected file is
2301 silcd/command_reply.c.
2303 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2305 * Distribute to the channel passphrase in CMODE_CHANGE notify.
2306 Updated specs and implemented it. Affected file silcd/command.c,
2307 silcd/packet_send.c and silcd/packet_receive.c.
2309 * Implemented the <founder auth> payload handling in the JOIN
2310 command. If provided all conditions for channel joining
2311 except requirement to provide correct passphrase can be
2312 overrided by the channel founder. Updated the protocol specs.
2313 Affected file silcd/command.c.
2315 Added support for founder auth in JOIN command in client
2316 library. Fixed the parsing of the JOIN command now to support
2317 all options as they should be. The affected file is
2318 lib/silcclient/command.c.
2320 * Optimized the WHOIS and IDENTIFY commands to send the request
2321 to router only if it includes nicknames or other names. If
2322 they include only IDs then check the local cache first before
2323 routing. Affected file is silcd/command.c.
2325 * Added channels topic announcements. Affected file is
2326 silcd/packet_receive.c and silcd/server.c.
2328 * Fixed the silc_server_send_notify_topic_set to really destine
2329 the packet to channel. Affected file silcd/packet_send.c.
2331 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
2332 library. Affected file lib/silcclient/client_notify.c.
2334 * Added UMODE announcements. Affected file silcd/server.c.
2336 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2338 * Memory leak fixes in:
2340 lib/silcutil/silcsockconn.c
2341 lib/silcske/silcske.c
2342 lib/silcske/groups.c
2344 lib/silccrypt/silcpkcs.c
2345 lib/silccore/silccommand.c
2346 lib/silccore/silcidcache.c
2351 * ROBOdoc documented the lib/silcske/groups.h file and a
2352 bit changed the interface for better.
2354 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2356 * Update the client entry context in the ID cache after
2357 nick change. Affected file lib/silcclient/command.c.
2358 Fixes the CUMODE command when regaining founder privileges,
2359 and a little WHOIS problem.
2361 * Fixed silc_net_gethostbyname to correctly call the
2362 inet_ntop. Affected file lib/silcutil/silcnet.c.
2364 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2366 * Added IPv6 support checking to the configure.in.pre, added
2367 also --enable-ipv6 option to override the check. Affected
2368 file configure.in.pre.
2370 * The silc_thread_create now calls the start function
2371 directly if threads support is not compiled in. Removes
2372 ugly #ifdef's from generic code. Affected files are
2373 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
2375 * Added silc_net_gethostby[name/addr]_async to asynchronously
2376 resolve. Affected files are lib/silcutil/silcnet.[ch].
2378 * Added support for rendering IPv6 based server, client and
2379 channel IDs. Affected file lib/silcutil/silcutil.c.
2381 * Added support for creating IPv6 based server IDs. Affected
2382 file is silcd/serverid.c.
2384 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2386 * Added silc_net_gethostby[addr/name] into the
2387 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
2388 routines. Added silc_net_is_ip[4/6]. Affected file is
2389 lib/silcutil/unix/silcunixnet.c. All routines that take
2390 address as argument now supports both IPv4 and IPv6 addresses.
2392 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2394 * Fixed LIST command reply sending in server. Affected file
2397 * Server now sends the kicker's client ID in the KICK notify
2398 to the kicked client. Affected file silcd/command.c.
2400 * The client library now parses the kickers client ID and
2401 UI displays it. Affected files lib/silcclient/client_notify.c
2402 and irssi/src/silc/core/silc-channels.c, module-formats.c.
2404 * Made all payload parsing function prototypes consistent.
2405 They all take now const unsigned char * and uint32 pair as
2406 the payload data instead of SilcBuffer. Changes all around
2407 the source tree. Other unsigned char* -> const unsigned char*
2408 changes around the tree as well.
2410 * Optimized SFTP client and server packet sending not to
2411 allocate new buffer for each packet but to recycle the
2412 first allocated buffer. Affected files are
2413 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
2415 * Optimized the SFTP client to use SilcList instead of
2416 SilcDList for requests, because it is faster. Affected file
2417 is lib/silcsftp/sftp_client.c.
2419 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
2420 into lib/silccore/silcid.[ch].
2422 Renamed silcpayload.[ch] into silcargument.[ch].
2424 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2426 * If client entry is deleted with active key agreement
2427 session, abort the session.
2429 The silc_client_abort_key_agreement now calls the completion
2430 callback with new SILC_KEY_AGREEMENT_ABORTED status.
2432 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
2435 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2437 * Don't use __restrict in older GCC's. Affected file is
2438 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
2440 * silc_net_localhost now attempts to reverse lookup the
2441 IP/hostname. Affected file lib/silcutil/silcnet.c.
2443 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
2444 command. It can be used to gain founder privileges at
2445 the same time when joining the channel.
2447 Defined that the SILC_NOTIFY_TYPE_KICKED send the
2448 kicker's client ID as well. Updated protocol specs.
2450 Defined that the server must send SILC_COMMAND_IDENTIFY
2451 command reply with error status to client who sent
2452 private message with invalid client ID.
2454 Updated the protocol specification.
2456 * Added silc_server_send_command_reply to send any
2457 command reply. Affected file silcd/packet_send.[ch].
2459 * Added silc_id_payload_encode_data to encode ID payload
2460 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
2462 * The server now send IDENTIFY command reply with error
2463 status if client ID in private message is invalid. Affected
2464 file silcd/packet_receive.c.
2466 * Save the server key file with server's IP address in
2467 the filename instead of hostname. The affected file is
2468 irssi/src/silc/core/client_ops.c.
2470 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2472 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
2475 * Added libtool support for compiling shared objects in
2476 lib/silcsim. Affected file configure.in.pre and
2477 lib/silcsim/Makefile.am. Original patch by cras.
2479 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2481 * Pid file configuration, and server's config file fixes
2482 patch by toma. Updated CREDITS file.
2484 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2486 * Fixed silc_client_channel_message to not try to decrypt
2487 the message twice if it resolved the destination client
2488 information. This could cause of dropping one channel
2489 message. Affected file lib/silcclient/client_channel.c.
2491 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2493 * Added silc_client_run_one into lib/silcclient/silcapi.h and
2494 lib/silcclient/client.c. This function is used when the SILC
2495 Client is run under some other scheduler, or event loop or
2496 main loop. On GUI applications, for example this may be
2497 desired to used to run the client under the GUI application's
2498 main loop. Typically the GUI application would register an
2499 idle task that calls this function multiple times in a second
2500 to quickly process the SILC specific data.
2502 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2504 * Fixed silc_server_drop() for dropping the supplementary
2505 groups as well, this could cause a security hole on some
2508 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2510 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
2513 * Write PID file after dropping privileges. Added -F option
2514 to run server on foreground. A patch by debolaz.
2515 Affected files silcd/server.c, silcd/silcd.c.
2517 * Fixed MOTD to return the MOTD file server name. Affected
2518 file silcd/command.c.
2520 * Added INFO command reply handling to the Irssi SILC Client.
2521 Affected file irssi/src/silc/core/client_ops.c.
2523 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2525 * Fixed the silc_idcache_list_* routines to really support
2526 the dynamic list. Fixes a crash. Affected file is
2527 lib/silccore/silcidcache.c.
2529 * Fixed the LIST command reply to really call LIST command's
2530 pending callbacks. Affected file silcd/command_reply.c.
2532 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2534 * Update conn->local_entry->nickname after giving NICK
2535 command. Affected file lib/silcclient/command.c.
2537 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
2539 * Added the [pid] option to the silcd configuration file
2541 Affected files: serverconfig.[ch] and silcd.c
2543 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2545 * Save fingerprint in WHOIS command reply in server.
2546 Affected file silcd/command_reply.c.
2548 * Fixed NICK commands pending callback registration.
2549 Affected file lib/silcclient/command.c.
2551 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2553 * Use ++server->cmd_ident when sending commands in server,
2554 instead of random number. Affected file silcd/command.c.
2556 * Fixed GETKEY command reply to call actually GETKEY pending
2557 command callbacks. Affected file silcd/command_reply.c.
2559 * A bit stricter check for nicknames. Check for same nickname
2560 in NICK command also. Affected file silcd/command.c.
2562 * Do not call INFO command everytime client ID changes, only
2563 during first connecting. Affected file lib/silcclient/client.c.
2565 * Set the new nickname only after successful command reply for
2566 NICK command is returned by server. Affected file
2567 lib/silcclient/command.c.
2569 * Remove nicknames from nicklist during server_signoff notify.
2570 Should fix /NAMES bit more. The affected file is
2571 irssi/src/silc/core/silc-channels.c.
2573 * Added `fingerprint' field to the SilcIDListData in the
2574 silcd/idlist.h to hold the fingerprint of the client's
2577 Send the fingerprint of the client's public key in WHOIS
2580 Affected files silcd/command.c, and silcd/idlist.[ch].
2582 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
2583 create fingerprint from given data.
2585 * Show the fingerprint of the client's public key in WHOIS.
2586 Affected files irssi/src/module-formats.[ch] and
2587 irssi/src/silc/core/client_ops.c.
2589 * Format the multiple same nicknames also during JOIN and
2590 NICK_CHANGE notifys. Affected file is
2591 lib/silcclient/client_notify.c.
2593 * Do not print error on screen for invalid private message
2594 payload since it can come if someone is sending private
2595 messages with wrong key. Affected file
2596 lib/silccore/silcprivate.c.
2598 * Fixed multiple concurrent /PING crash. Affected file
2599 lib/silcclient/command.c.
2601 * Changed the wrong ID encoding. All IP addresses must be
2602 in MSB first order in encoded format. They were encoded
2603 wrong and was in LSB format. Affected files are
2604 silcd/serverid.c, lib/silcutil/silcutil.c.
2606 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
2608 * Call the `connect' client operation through the scheduler
2609 in case of error. Affected file lib/silcclient/client.c.
2611 * Call the `failure' client operation even if the error
2612 occurred locally during a protocol. Affected file is
2613 lib/silcclient/protocol.c.
2615 * Added support of sending LIST command to router from normal
2616 server. This way normal server can get list of all channels
2617 in the network too. Fixed the channel list sending in the
2618 server too. Affected files are silcd/command.c, and
2619 silcd/command_reply.[ch].
2621 * Added silc_server_update_channels_by_server and
2622 silc_server_remove_channels_by_server. They are used during
2623 disconnection of primary router and in backup router protocol.
2624 Affected file silcd/server_util.[ch], silcd/server.c and
2625 silcd/server_backup.c.
2627 * Fixed channel adding to global list in IDENTIFY command
2628 reply in server. Affected file silcd/command_reply.c.
2630 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2632 * If the incoming packet type is REKEY or REKEY_DONE process
2633 that packet always synchronously. Fixes yet another MAC
2634 failed error on slow (dialup) connections. Affected file
2635 lib/silcclient/client.c and silcd/server.c.
2637 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2639 * Call check_version SKE callback for initiator too. Affected
2640 file lib/silcske/silcske.c.
2642 * Implemented fix for security hole found in the SKE that was
2643 fixed in the specification few days back; the initiator's
2644 public key is now added to the HASH value computation.
2645 Added backwards support for the old way of doing it too, for
2646 old clients and old servers. Affected file is
2647 lib/silcske/silcske.c.
2649 * Enabled mutual authentication by default in SKE. If initiator
2650 is not providing mutual authentication the responder will
2651 force it. This will provide the proof of posession of the
2652 private key for responder. The affected files are
2653 lib/silcclient/protocol.c and silcd/protocol.c.
2655 * Do not cache anymore the server's public key during SKE.
2656 We do mutual authentication so the proof of posession of
2657 private key is done, and if the server is authenticated in
2658 conn auth protocol with public key we must have the public
2659 key already. Affected file silcd/protocol.c.
2661 * Added new global debug variable: silc_debug_hexdump. If
2662 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
2663 file lib/silcutil/silclog.[ch].
2665 * Fixed compilation warning due to char * -> const char *.
2666 Affected files lib/silcutil/silcnet.h, and
2667 lib/silccore/silcauth.[ch].
2669 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2671 * Fixed CMODE command when new channel key was created. If
2672 the creation failed the old key was removed. Next time giving
2673 same command would crash the server since the old key was
2674 freed already. Affected file silcd/command.c.
2676 * Fixed the silc_server_announce_get_channels to not crash
2677 on reconnect. Affected file silcd/server.c.
2679 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2681 * Added silc_log_set_debug_string function to set a regex
2682 string to match for debug output. Only the function names,
2683 or filenames matching the given debug string is actually
2684 printed. This way it is possible to filter out those debug
2685 strings that user is not interested in.
2687 Fixed a bug in silc_string_regexify.
2689 Affected files lib/silcutil/silclog.[ch], and
2690 lib/silcutil/unix/silcunixutil.c.
2692 * Changed the -d options in both server and Irssi SILC client
2693 to take the debug string as argument. Affected files
2694 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
2696 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2698 * Added silc_hash_babbleprint to create a Bubble Babble
2699 Encoded fingerprint. The encoding is developed by Antti
2700 Huima (draft-huima-babble-01.txt), and it creates human
2701 readable strings out of binary data. Affected file
2702 lib/silccrypt/silchash.[ch].
2704 * Print the babble print now in addition of fingerprint as well
2705 in Irssi SILC client. Affected files are
2706 irssi/src/fe-common/silc/module-formats.[ch],
2707 irssi/src/fe-common/silc/core/client_ops.c.
2709 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2711 * Fixed a security problem found in SKE. The initiator's
2712 public key too is now added to the HASH hash value creation
2713 which is signed by the responder to create the SIGN value.
2714 This will prevent anyone in the middle to lie to the responder
2715 about the initiator's public key. If this is done now, the
2716 man in the middle will get caught. Updated the protocol
2719 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2721 * Better installation directory handling. Configure module
2722 paths and other paths automatically to example_silc* files
2723 in doc/. A patch by toma.
2725 * Fixed compiler warning from MPI library, and from SILC RNG.
2728 * Added SILC_SERVER_PID_FILE to define the pid file for server.
2729 It can be configured with ./configure. A patch by toma.
2731 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2733 * Find correct make to use in prepare-clean. A patch by
2734 toma. Affected file prepare-clean.
2736 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
2738 * Added irssi variables use_auto_addr, auto_bind_ip,
2739 auto_bind_port and auto_public_ip.
2741 * Changed the interface for silc_client_send_key_agreement
2742 in lib/silcclient/silcapi.h
2746 irssi/src/silc/core/silc-core.c
2748 lib/silcclient/silcapi.h
2749 irssi/src/silc/core/silc-channels.c
2750 lib/silcclient/client_keyagr.c
2753 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2755 * Added silc_pkcs_public_key_compare to compare two
2756 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
2758 * Check that the client who set the founder mode on the
2759 channel is the same client that is giving the founder
2760 mode to itself. It is done by comparing the saved public
2761 key (it is saved even in the authentication is passphrase).
2762 Affected file silcd/command.c.
2764 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2766 * Do not process packet for disconnected socket connection.
2767 Affected file lib/silccore/silcpacket.c.
2769 * Process the DISCONNECT packet through scheduler in the
2770 client library. Affected file lib/silcclient/client.c.
2772 * Fixed the silc_client_packet_parse to not to increase
2773 the packet sequence number if the conn->sock and the
2774 current socket connection is not same. This can happen
2775 for example during key agreement when the conn includes
2776 multiple socket connections (listeners). Affected file
2777 lib/silcclient/client.c.
2779 * The sender of the file transfer request now provides also
2780 the pointer (listener) for the key exchange protocol. If
2781 the listener cannot be created then it sends empty key
2782 agreement and lets the receiver provide the listener.
2784 Added `local_ip' and `local_port' arguments to the
2785 silc_client_file_send. If they are provided they are used,
2786 if not then it will attempt to find local IP address, if
2787 not found or bind fails then the remote client will provide
2790 Affected files are lib/silcclient/client_ftp.c and
2791 lib/silcclient/silcapi.h.
2793 * Extended the FILE SEND command to support defining the
2794 local IP and port for key exchange listener. They are
2795 optional. Affected file irssi/src/silc/core/silc-servers.c.
2797 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2799 * Defined to WHOIS command reply the sending of fingerprint
2800 of the client's public key (if the proof of posession of the
2801 corresponding private key is verified by the server).
2802 Updated to the protocol specification.
2804 * Added support of receiving the client's public key's
2805 fingerprint in command reply in client library. Affected
2806 file is lib/silcclient/command_reply.c, and
2807 lib/silcclient/idlist.[ch].
2809 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2811 * Do not send over 128 chars long nickname to the server
2812 in NICK command. Affected file lib/silcclient/command.c.
2814 * Do not send over 256 chars long channel names to the server
2815 in JOIN command. Affected file lib/silcclient/command.c.
2817 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2819 * Assure that silc_server_close_connection cannot be called
2820 twice for same socket context. Affected file is
2823 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2825 * Send error message to application if opening file for
2826 writing during file transfer fails. Affected file is
2827 lib/silcclient/client_ftp.c.
2829 Remove all file transfer sessions for a client that we're
2830 removing from ID cache.
2832 Affected file is lib/silcclient/client_ftp.c.
2834 * Fixed silc_net_addr2bin to return correct address. Affected
2835 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2837 * Fixed file transfer session removing on signoff notify.
2838 Affected file irssi/src/silc/core/silc-servers.c.
2840 * Added the SilcClientFileError to be returned in the monitor
2841 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
2842 Affected file lib/silcclient/silcapi.h.
2844 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2846 * Fixed a crash in silc_client_ftp_free_sessions and
2847 silc_client_ftp_session_free_client. Affected file
2848 lib/silcclient/client_ftp.c.
2850 * Added `disabled' field in the SilcChannelEntry in the server
2851 to indicate if the server entry is disabled. Affected file
2852 silcd/idlist.h, silcd/command[_reply].c.
2854 * SILC server adds now /var/run/silcd.pid everytime it is
2855 started. Affected file silcd/silcd.c.
2857 * Added silc_server_packet_send_clients to send a packet to
2858 the provided table of client entries. Affected file
2859 silcd/packet_send.[ch].
2861 * Fixed a crash in client resolving in client_prvmsg.c in
2862 client library. Affected file lib/silcclient/client_prvmsg.c.
2864 * Do not actually remove the client directly from ID cache
2865 during SERVER_SIGNOFF, but invalidate it. This way we
2866 preserve the WHOWAS info for the client. Affected file
2867 silcd/server_util.c.
2869 * Fixed SERVER_SIGNOFF notify handling in the server. The
2870 server is now able to process incoming SERVER_SIGNOFF notify
2871 for a server that it doesn't even know about. It will remove
2872 the clients provided in the notify. Affected file
2873 silcd/packet_receive.c.
2875 * Check for partial packet in data queue after every packet that
2876 was found from the queue. Return and wait for more data if
2877 there is partial data in queue. Affected file is
2878 lib/silccore/silcpacket.c.
2880 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2882 * Added SilcClietFileError enum to indicate error in
2883 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
2884 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
2885 Affected files lib/silcclient/silcapi.h and
2886 lib/silcclient/client_ftp.c.
2888 * Check that newsize in silc_buffer_realloc is larger than
2889 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
2891 * Added better monitor of file transfers. It now monitors
2892 key agreement protocol during the file transfer too. Added
2893 error reporting too. Affected files
2894 irssi/src/silc/core/silc-servers.c,
2895 irssi/src/fe-common/silc/module-formats.[ch].
2897 * Wrote a help file for FILE command.
2899 * Added silc_rng_global_get_byte_fast to get not-so-secure
2900 random data as fast as possible. Random data is read from
2901 /dev/urandom if available and from the SILC RNG if not
2902 available. It is used in padding generation. Affected file
2903 lib/silccrypt/silcrng.[ch].
2905 * All packets in client library are now processed synchronously.
2906 Optimized packet processing a lot. Affected file
2907 lib/silcclient/client.c.
2909 * All server connection packets are processing synchronously
2910 now in server, to optimize packet processing. Affected file
2913 * Include files are installed now only in Toolkit distribution
2914 if make install is given. Affected files: all Makefile.am's.
2916 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2918 * Assure that silc_client_notify_by_server_resolve does not
2919 resolve the client information multiple times. If it cannot
2920 be found by the first it cannot be found at all. Affected
2921 file lib/silcclient/client_notify.c.
2923 * Fixed WHOWAS command reply calling. Affected file
2924 lib/silcclient/command_reply.c.
2926 * Removed all references to silc_idlist_get_client from the
2927 Irssi SILC client since that call is internal call used by
2928 the library. The Irssi SILC client will use now client
2929 retrieval functions found in silcapi.h.
2931 * Fixed a bug in resolving nickname info before sending
2932 private message. It used freed memory. Affected file
2933 irssi/src/silc/core/silc-servers.c.
2935 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2937 * Assure my_channels statistics cannot go negative in server.
2938 Affected files silcd/server.c, silcd/server_util.c.
2940 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2942 * Upgraded dotconf 1.0.2 to 1.0.6 in lib/dotconf.
2944 Tue Oct 23 13:51:19 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2946 * Win32 Toolkit changes. Affected files
2947 win32/silc.dsw, win32/libsilc/libsilc.def,
2948 win32/libsilcclient/libsilc.def,
2949 lib/silcutil/silcutil.c, and
2950 lib/sftp/sftp_fs_memory.c.
2952 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2954 * Added silc_net_localip to return local host's IP address.
2955 Affected file lib/silcutil/silcnet.[ch].
2957 * If key exchange or rekey protocol is active for a connection
2958 parse all packets syncronously since there might be packets
2959 in packet queue that we are not able to process without first
2960 processing packets before them. Affected file silcd/server,
2961 lib/silcclient/client.c.
2963 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2964 whether library should continue processing the packet.
2965 Affected file lib/silccore/silcpacket.h.
2967 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
2968 SilcSFTPMonitorData to SFTP server to monitor various
2969 SFTP client requests. Affected file lib/silcsftp/silcsftp.h,
2970 lib/silcsftp/sftp_server.c.
2972 * Added silc_file_size to return file size. Affected file
2973 lib/silcutil/silcutil.[ch].
2975 * Implemented the file transfer support for the client library.
2976 Added preliminary support for simple client to client one-file
2977 transmission. Affected file lib/silcclient/client_ftp.c,
2978 lib/silccilent/client.[ch].
2980 * Added new local command FILE to the Irssi SILC Client.
2981 It is used to perform the file transfer. It has subcommands
2982 SEND, RECEIVE, SHOW and CLOSE. Affected files
2983 irssi/src/silc/core/client_ops.c,
2984 irssi/src/silc/core/silc-server.[ch].
2986 Mon Oct 22 12:50:08 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2988 * Relay the SILC_PACKET_FTP in the server. Affected files
2989 silcd/server.c and silcd/packet_receive.c.

2993 * Renamed silc_file_read and silc_file_write to functions
2994 silc_file_readfile and silc_file_writefile. Added function
2995 silc_file_open and silc_file_close. Affected files
2996 lib/silcutil/silcutil.[ch].
2998 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3000 * Resolve the client info when received private message or
3001 channel message for a client which nickname we don't know.
3002 Affected files lib/silcclient/client_prvmsg.c and
3003 lib/silcclient/client_channel.c.
3005 * Do not crash in /KEY if client is not connected. Affected
3006 file irssi/src/silc/core/silc-channels.c.
3008 * Added SilcClientStatus field to the SilcClientEntry in the
3009 lib/silcclient/idlist.h.
3011 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
3012 is incomplete and is being resolved, it won't be resolved
3015 Make sure also that USERS command reply does not resolve
3016 twice information. Affected file is
3017 lib/silcclient/command_reply.c.
3019 Make sure that silc_client_get_clients_by_list does not
3020 resolve twice same information.
3022 * Check for valid client->id in the silc_server_free_client_data.
3023 Affected file silcd/server.c.
3025 * Fixed /GETKEY nick@server not to crash if the server entry
3026 is not found. Affected file lib/silcclient/command.c.
3028 * Fixed the silc_server_check_cmode_rights to check the
3029 requested modes correctly. Affected file silcd/command.c.
3031 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3033 * Better checks for non-printable chars in nick added.
3034 Affected file silcd/command.c.
3036 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3038 * Call the silc_server_udpate_servers_by_server in the
3039 primary router that comes back online in the backup resuming
3040 protocol. Otherwise it routes packets wrong. Affected file
3041 silcd/server_util.[ch], silcd/server_backup.c.
3043 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3045 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
3046 lib/silcutil/silcbuffmt.[ch].
3048 * Redefined the SILC packet header to include the padding
3049 length. Affected file lib/silccore/silcpacket.[ch].
3051 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
3052 length for maximum padding up to 128 bytes). Affected
3053 file lib/silccore/silcpacket.h.
3055 * Removed all backwards support for old 0.5.x MAC thingies.
3056 The SILC packet header change makes it impossible to be
3057 backwards compatible.
3059 * Send the ENDING packet with timeout in the backup resuming
3060 protocol. This is to assure that all routers has connected
3061 to the primary router. Affected file silcd/server_backup.c.
3063 * Changed the RNG to take the first IV from random data. It
3064 used to take it from zero actually. Changed the RNG also
3065 to use /dev/urandom during session. /dev/random is used
3066 in initialization. Affected file lib/silccrypt/silcrng.[ch].
3068 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3070 * Changed the SILC packet header to have the first two bytes
3071 (the packet length) encrypted. Affected files aroung the
3072 code tree, lib/silccore/silcpacket.[ch]. Removed the
3073 SilcPacketCheckDecrypt callback. It is not needed anymore
3074 since the silc_packet_receive_process will determine now
3075 whether the packet is normal or special.
3077 * Implemented the unidirectional MAC keys. Affected files
3078 lib/silcske/silcske.c, silcd/protocol.c and
3079 lib/silcclient/protocol.c.
3081 * Implemented the packet sequence number to the MAC computation.
3082 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
3083 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
3084 lib/silcclient/protocol.c.
3086 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3088 * Allow backup router to announce servers. All servers
3089 announced by backup router are added to the global list
3090 automatically. Update hte server's socket to our primary
3091 router also when backup router announces a server.
3092 Affected file silcd/packet_receive.c.
3094 * Do not update the client->router in the function
3095 silc_server_udpate_clients_by_server if the client is on
3096 global list. We might fail to find any specific server
3097 for locally connected clients and local cell clients. They
3098 should still use the `from' and not `to' as client->router.
3099 This fixes backup router resuming protocol. Affected file
3100 silcd/server_util.c.
3102 * Decrease channel statistics count only if the channel
3103 deletion worked. Affected files are silcd/server.c and
3104 silcd/server_util.c.
3106 * Added silc_server_update_servers_by_server to update origin
3107 of all server entries. Used during backup router protocol.
3108 Affected files silcd/server_util.[ch], silcd/server.c. and
3109 silcd/backup_router.c.
3111 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
3112 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
3113 silc_hmac_get_hash and silc_hmac_get_name. Affected file
3114 lib/silccrypt/silchmac.c.
3116 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3118 * Assure that router cannot reroute the same channel message
3119 to the sender. Affected file silcd/packet_receive.c.
3121 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3123 * Made better checks that the channel message is not sent
3124 to the router it came from. Affected file is
3125 silcd/packet_send.c. Fixed memory leak too.
3127 * Announce informations for incoming router connection, but
3128 only after checking if it is replaced by backup router.
3129 Affected file silcd/packet_receive.c.
3131 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3133 * Fixed the backup resuming protocol to work in multiple
3134 router environment. Affected file silcd/server_backup.c.
3136 * Route packet only to one router in the function
3137 silc_server_packet_send_to_channel. Affected file is
3138 silcd/packet_send.c.
3140 * Fixed silc_server_send_notify_dest to set the broadcast
3141 flag. Fixed the silc_server_send_notify_topic to actually
3142 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
3143 Affected file silcd/packet_send.c.
3145 * Changed the SFTP Filesystem interface. Changed the
3146 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
3147 the filesystem operation function. The SilcSFTPFilesystem
3148 is now a context that is allocated by all filesystem allocation
3149 functions and it already includes the operations structure
3150 and filesystem specific context. It is given as argument
3151 now to the silc_sftp_server_start. This made the interface
3152 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
3153 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
3155 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3157 * Changed the backup router adding and getting interfaces
3158 in the server. The router that will be replaced by the
3159 specified backup router is now sent as argument. Affected
3160 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
3163 * Added silc_net_addr2bin_ne to return the binary form of
3164 the IP address in network byte order. Affected files
3165 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
3167 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3169 * Check for existing server ID in silc_server_new_server
3170 and in silc_server_connect_to_router_final and remove the
3171 old entry if it exists. Affected file silcd/packet_receive.c,
3174 * Send the channel message always to only one router, either
3175 in upstream or downstream. Affected file is
3176 silcd/packet_send.c.
3178 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3180 * Wrote the definition of the backup resuming protocol to the
3181 protocol specification.
3183 * Removed one redundant channel key generation from normal
3184 server during joining procedure. Removed one redundant
3185 channel key sending from server to router during joining
3186 procedure. Affected file silcd/command.c.
3188 * Made minor bugfixes to the backup router resuming protocol.
3189 Affected file silcd/server_backup.c, server.c.
3191 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3193 * Added --disable-asm configuration option. Affected files
3194 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
3197 * Implemented the backup resuming protocol that is used to
3198 resume the primary router position in the cell after the
3199 primary router comes back online. Affected files
3200 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
3201 and silcd/server_util.[ch].
3203 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3205 * Sleep two (2) seconds after sending QUIT command to server.
3206 Affected file lib/silcclient/command.c.
3208 * Assure that if outgoing data buffer is pending do not force
3209 send any data. Affected file silcd/packet_send.c.
3211 * Assure that if outgoing data buffer is pending do not force
3212 send any data. Affected file lib/silcclient/client.c.
3214 * Implemented the backup router support when the primary router
3215 goes down. The servers and routers can now use the backup
3216 router as new primary router without loosing connectivity.
3218 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3220 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
3221 in the server to indicate disabled entry. All data read
3222 from the connection will be ignored and no data is sent
3223 for entry that is disabled. Affected files are
3224 silcd/idlist.h, silcd/server.c.
3226 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3228 * Created SFTP client and server test programs in the
3229 lib/silcsftp/tests directory.
3231 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3233 * Implemented memory filesystem (virtual filesystem) for
3234 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
3237 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3239 * Implemented the SFTP (SSH File Transfer Protocol) to the
3240 lib/silcsftp. It includes SFTP client and SFTP server
3243 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3245 * Moved lib/silccore/silcprotocol.[ch] to the
3246 lib/silcutil library.
3248 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
3249 take variable argument list pointer as argument. Affected
3250 file lib/silcutil/silcbuffmt.[ch].
3252 * Added silc_buffer_set function that is used to set data
3253 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
3254 Affected file lib/silcutil/silcbuffer.h.
3256 * Changed various routines in the core library to use the new
3257 silc_buffer_set instead of allocating new buffer only for
3260 * Added 64-bit value formatting and unformatting support to the
3261 silc_buffer_[un]format routines. Affected file is
3262 lib/silcutil/silcbuffmt.[ch].
3264 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
3265 to includes/bitmove.h.
3267 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3269 * Fixed channel user mode saving in client library. Affected
3270 file lib/silcclient/command[_reply].c.
3272 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3274 * Defined the file transfer to the SILC Protocol. Added
3275 new packet type SILC_PACKET_FTP and defined File Transfer
3276 Payload. The mandatory file transfer protocol is SFTP
3277 (SSH File Transfer Protocol). Affected file in addition
3278 of the internet draft is lib/silccore/silcpacket.h.
3280 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
3281 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
3282 is used as part of backup router protocol when the primary
3283 router of the cell is back online and wishes to resume
3284 the position as primary router.
3286 * Redefined the MAC generation keys in the protocol. The
3287 same key is not used anymore in both direction. Both
3288 direction will now use different keys for sending and
3289 receiving. This fixes a potential security flaw. This
3290 change causes incompatibilities in the protocol.
3292 * Redefined also the MAC computation from the packet.
3293 An packet sequence number is now added to the MAC
3294 computation. This prevents possible replay attacks against
3295 the protocol. This change too causes incompatibilities
3298 Added `sequence' field to the SilcPacketContext to hold
3299 the current sequence number for the packet.
3301 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3303 * Added `created' field to the SilcIDListData in the file
3304 silcd/idlist.h to indicate the time when the entry was
3307 * Added `created' field to the SilcChannelEntry too. Affected
3308 file silcd/idlist.h.
3310 * Added `creation_time' aguments to all the announcement functions
3311 in the server. If it is provided then only the entries that
3312 was created after the provided time frame are actually
3313 announced. Affected file silcd/server.[ch].
3315 * The protocol says that the Channel ID's IP address must be
3316 based on the router's IP address. Added check for this in
3317 the silc_server_new_channel when processing incoming New Channel
3318 Payload. Affected file silcd/packet_receive.c.
3320 * Print out the correct version with --version in SILC client.
3321 Affected file irssi/src/silc/core/silc-core.c.
3323 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3325 * Fixed WHOWAS command to check for completnes of the client
3326 entry always, not just when the command is coming from client.
3327 Affected file silcd/command.c.
3329 * Added new function silc_server_packet_queue_purge to purge the
3330 outgoing data queue to the network. After the function returns
3331 it is guaranteed that the outgoing packet queue is empty.
3332 Affected file silcd/packet_send.[ch].
3334 * Purge the outgoing packet queue in the rekey protocol's final
3335 callback to assure that all rekey packets go to the network
3336 before quitting the protocol. Affected file silcd/server.c.
3338 * Added silc_client_packet_queue_parse as similar function as
3339 in server to the client library. The affected file is
3340 lib/silcclient/client.c.
3342 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3344 * Splitted silcd/server.c and created silcd/server_util.[ch]
3345 for utility functions.
3347 * Added new socket flag SILC_SF_DISABLED to indicate that the
3348 connection is open but nothing can be sent to or received from
3349 the connection. Affected file lib/silcutil/silsockconn.[ch].
3350 The checking for disabled socket is checked in the low level
3351 silc_socket_write and silc_socket_read functions.
3353 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3355 * Allow only nicknames and channel names that fits into the
3356 7-bit unsigned char ASCII set. Affected file silcd/command.c.
3358 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3360 * When processing JOIN command reply in server check that if
3361 the channel exists in our global list we'll move it the local
3362 list. Affected file silcd/command_reply.c.
3364 * Fixed the check whether client is joined on the channel already
3365 in JOIN command. Affected file lib/silcclient/command.c.
3367 * Fixed the JOIN command reply to check whether the channel
3368 already exists. Affected file lib/silcclient/command_reply.c.
3370 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3372 * Added silc_ske_status_string to map the SKE error numbers
3373 to readable strings. The affected files are
3374 lib/silcske/silcske[_status].[ch].
3376 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3378 * Do not show the private channels on the WHOIS channel list
3379 as it is not allowed by the protocol. The affected file is
3382 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3384 * Assure that the packet length digged from the actual packet
3385 is something sensible in the silc_packet_decrypt_rest_special
3386 in lib/silccrypt/silcpacket.c.
3388 * Free and NULL the allocated pointer in silc_hmac_alloc if
3389 the HMAC allocation fails. The affected file is
3390 lib/silccrypt/silchmac.c.
3392 * Print the selected security properties to the log files in
3393 the server. Affected file silcd/protocol.c.
3395 * Add SKE's reference counter even if calling the completion
3396 callback manually. Otherwise it goes negative, although it
3397 does not cause any problems. The affected file is
3398 lib/silcske/silcske.c.
3400 * Remove the client entry with short timeout after giving the
3401 KILL command. Affected file lib/silcclient/command.c.
3403 * Fixed to send error reply in WHOIS and IDENTIFY commands in
3404 case all found clients are already disconnected (WHOWAS would
3405 found them) in the server. Affected file silcd/command.c.
3407 * Update the last_receive (time of last data received) to be
3408 updated only when received private or channel message so that
3409 the idle time showed in WHOIS makes more sense.
3411 * Added boolean field `valid' in to the SilcClientEntry in the
3412 client library to indicate whether the entry is valid or not.
3413 This fixes the nickname change bug on channel when changing
3414 the nickname to be same than the old (like nick to Nick) the
3415 nickname formatter doesn't set the new nick anymore to Nick@host.
3416 Affected file lib/silcclient/idlist.[ch].
3418 * Now actually fixed the nickname changing on disconnection.
3419 Added new function silc_change_nick to the Irssi SILC Client.
3420 Affected file irssi/src/silc/core/client_ops.c,
3421 irssi/src/silc/core/silc-nicklist.[ch].
3423 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3425 * Check that the public key exists in the GETKEY command before
3426 trying to encode it. Affected file silcd/command.c.
3428 * Print some notifications on received public keys with GETKEY
3429 command in the Irssi SILC Client. Affected files are
3430 irssi/src/fe-common/silc/module-formats.[ch],
3431 irssi/src/silc/core/client_ops.c.
3433 * Use IDENTIFY command to resolve the server information in the
3434 GETKEY command instead of INFO command. Affected file
3435 lib/silcclient/command.c.
3437 * All command reply functions in the client library now calls
3438 the pending command reply callbacks even if an error has
3439 occurred. The server has done this a long time and now it was
3440 time to move the client library to this as well. Now all
3441 errors can be delivered back to the pending command reply
3442 callbacks if necessary. Affected files are
3443 lib/silcclient/command[_reply].[ch].
3445 * Change the nickname on disconnection back to the username
3446 because in reconnect the server will enforce it to it anyway.
3447 Affected file irssi/src/silc/core/silc-servers.c.
3449 * Fixed a config file parsing bug in the Irssi SILC client.
3450 Affected file irssi/src/silc/core/clientconfig.c.
3452 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3454 * When printing the channel mode on JOIN, verify that the
3455 channel key and channel's HMAC are valid. Affected file
3456 irssi/src/silc/core/client_ops.c.
3458 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3460 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
3461 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
3462 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
3464 * Removed channel key rekey task deleting from the function
3465 silc_server_save_channel_key. Affected file silcd/server.c.
3466 Added explicit timeout task context instead that is used to
3467 delete the task if we are registering a new task before the
3468 new task has elapsed.
3470 * When channel key rekey occurs the client library now saves
3471 the old channel key for a short period of time (10 seconds) and
3472 is able to use it in case some is still sending channel
3473 messages encrypted with the old key after the rekey. Affected
3474 file lib/silcclient/[idlist.h|client_channel.c].
3476 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3478 * Added check to the silc_server_new_id_real to not accept
3479 new ID if it is the sender's own ID. Affected file is
3480 silcd/packet_receive.c.
3482 * Assure that we do not announce ourself or the one we've
3483 sending our announcements when we're router and are announcing
3484 servers to our primary router. Affected file silcd/server.c.
3486 * Fixed silc_server_command_identify_check_client to assemble
3487 correct WHOIS packet. It send corrupted WHOIS packet and
3488 caused problem with router to router connections. Affected
3489 file silcd/command.c.
3491 Fixed also silc_server_command_whois_check the same way
3492 as for the IDENTIFY command.
3494 * Added new SilcIDListStatus to the server in the SilcIDListData
3495 structure. The status now includes the current status of
3496 the entry (like registered, resolved etc.). Affected file
3497 silcd/idlist.[ch]. Defined a bunch of different status types
3498 as well. This replaced the old boolean registered field as well.
3500 Added resolve_cmd_ident field to the SilcClientEntry structure
3501 too so that if the entry is for example being resolved so
3502 another command may attach to the same pending command reply
3503 without requiring to resolve the same entry again. This concept
3504 should optimize the WHOIS and the IDENTIFY resolving under
3505 heavy load by taking away unnecessary resolving for entries
3506 that are being resolved already.
3508 Added support for adding multiple pending commands for one
3509 command idenfier. Affected file silcd/command[_reply].[ch].
3511 * Fixed WHOIS and IDENTIFY save to remove the cache entry
3512 before deleting the data. Otherwise the hash table will have
3513 freed data in comparison functions. Affected file is
3514 silcd/command_reply.c.
3516 * Fixed silc_idlist_replace_client_id to add the new entry to
3517 the cache with NULL nickname. Otherwise there will be invalid
3518 memory as the nickname after the nickname is freed. Affected
3519 file silcd/packet_receive.c.
3521 * Fixed the silc_idlist_get_clients_by_hash. The entries was
3522 saved into wrong slots because the previous number of entries
3523 was not taken into account. Affected file silcd/idlist.c.
3524 Fixed same thing in silc_idlist_get_clients_by_nickname too.
3526 * If we are router and we receive JOIN notify to a channel that
3527 does not have any users then notified client is marked as the
3528 channel founder, as it is it. The affected file is
3529 silcd/packet_receive.c
3531 * Added to the extended hash table API's table_del_*ext functions
3532 the destructor as argument too, so that the caller can decide
3533 which destructor to use or whether to use destructor at all.
3534 Affected file lib/silcutil/silchashtable.[ch].
3536 * Fixed ID Cache purging. It actually deleted the entries from
3537 the hash table after the data was freed. The hash table ended
3538 up comparing freed memory. The affected file is
3539 lib/silccore/silcidcache.c.
3541 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3543 * Fixed Irssi SILC client's KILL command's HELP syntax.
3545 * The USERS command now resolves the detailed user information
3546 if the userinfo field is missing. Affected file is
3547 lib/silcclient/command_reply.c.
3549 * Do not print error in silc_file_read if the read file does
3550 not exist. Just silently return NULL. Affected file is
3551 lib/silcutil/silcutil.c.
3553 * Fixed the silc_log_output to not wine about NULL filename
3554 and to not create some bogus " " filename. Affected file is
3555 lib/silcutil/silclog.c.
3557 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3559 * Fixed various printing bugs on the user interface in the
3560 Irssi SILC Client. Minor changes that were forgotten from
3563 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3565 * Fixed the configure.in.pre and the compilation and distribution
3566 environment to support the new autoconf 2.52. That version is
3567 now required to compile the CVS trunk.
3569 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3571 * Renamed function silc_parse_nickname to silc_parse_userfqdn
3572 to generally parse user@fqdn format strings. Affected file
3573 lib/silcutil/silcutil.c.
3575 * Added nickname_format and nickname_force_format fields to the
3576 SilcClientParams structure. The first one defines the format
3577 for the nicknames that the library will enforce if the receives
3578 multiple same nicknames. The second one is boolean value and
3579 can be used to force the library to always enforce the format
3580 to the nicknames regardles whether there are multiple nicknames
3581 or not. This configurable formatting was employed to flexibly
3582 support accessing multiple nicknames from the user interface.
3583 The userinterface can now set the nicknames to what ever format
3584 they prefer. Affected file lib/silcclient/silcapi.h.
3586 Added function silc_client_nickname_format to the file
3587 lib/silcclient/idlist.c. It performs the nickname formatting.
3589 Added new field `hostname´ to the SilcClientEntry context.
3590 It holds the hostname of the client. Affected file is
3591 lib/silcclient/idlist.h.
3593 * Irssi SILC Client sets the nicknames in nick@hostn format.
3594 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
3595 irssi/src/silc/core/silc-core.c.
3597 The WHOIS printing now also shows both the real nickname and
3598 the formatted nickname so that user knows how to access the
3599 user if there are multiple same nicknames cached. Affected
3600 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
3601 printing formatting too to take the hostname now as a separate
3602 argument. The Affected file is
3603 irssi/src/fe-common/silc/modules-formats.[ch].
3605 * Changed the silc_client_get_clients_local to accept the formatted
3606 nickname as argument. It accepts the real nickname too but the
3607 formatted nickname can be used to find the true entry from
3608 multiple entries. Affected file lib/silcclient/silcapi.h and
3609 lib/silcclient/idlist.c.
3611 * Added nickname_format_parse field to the SilcClientParams.
3612 It is a callback function provided by the application to parse
3613 the nickname out of the formatted nickname string. The library
3614 calls it to get the nickname from the formatted string. Since
3615 the application generally knows better the format of the nickname
3616 string it parses it instead of the library, even though library
3617 encodes the formatted string. If the callback function is not
3618 provided then the library will use the string as is. The
3619 affected file is lib/silcclient/silcapi.h.
3621 * All the nickname strings passed to the client library in
3622 commands are now expected to be formatted nickname strings.
3623 If the command does not support the formatted nickname string
3624 it will assume that the sent string is the actual nickname.
3625 Affected file lib/silcclient/command.c.
3627 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3629 * Added public key authentication support to OPER and SILCOPER
3630 commands in the client library. Affected file is
3631 lib/silcclient/command.c.
3633 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3635 * Changed the get_auth_methdod client operation to be asynchronous.
3636 It can be async if the application resolves the authentication
3637 method from the server during the negotiation. Added new
3638 SilcGetAuthMeth completion callback that the application will
3639 call after resolving the authentication method.
3641 Added function silc_client_request_authentication_method that
3642 the application can use to resolve the authentication method
3643 from the server. Added also SilcConnectionAuthRequest callback
3644 that the library will call after the server has replied. The
3645 application can call this function if it does not know the
3646 current authentication method.
3648 Affected files are lib/silcclient/client.c and
3649 lib/silcclient/silcapi.h.
3651 * The Irssi SILC client now automatically resolves the authentication
3652 method incase any configuration information is not present (and
3653 currently there never is). The affected file is
3654 irssi/src/silc/core/client_ops.c.
3656 * Fixed public key authentication from the client library.
3657 Affected file lib/silcclient/protocol.c. Changed also the
3658 protocol specification about the public key authentication in
3659 the connection authentication protocol. The actual data to be
3660 signed is now computed with a hash function before signing.
3662 * Fixed the public key authentication from the server as well.
3663 Affected file silcd/protocol.c.
3665 * Removed the mlock()'s from the memory allocation routines.
3666 Affected file lib/silcutil/silcmemory.c. The ./configure does
3667 not check anymore for the mlock(). Affected file is
3670 * Fixed USERS command in server to allow the execution of the
3671 command for private and secret channels if the client sending
3672 the command is on the channel. Affected file silcd/command.c.
3674 * Fixed silc_client_get_clients_local to return the clients
3675 count correctly. It could return wrong value. Affected file
3676 lib/silcclient/idlist.c.
3678 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3680 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
3681 types. The assembler optimizations seemed not to like 64-bit
3682 data types. The assmebler optimizations thus are now enabled
3683 also for BSD systems as opposed to only enable them for Linux.
3685 * Do not check for threads at all on BSD systems. Affected
3686 file configure.in.pre.
3688 * Removed -n and -h options from the Irssi SILC Client since
3689 they are not used in silc.
3691 * Fixed the prime generation to assure that the first digit
3692 of the generated random number is not zero since our conversion
3693 routines does not like number strings that starts with zero
3694 digit. If zero digit is seen the random number is regenerated.
3695 This caused some corrupted RSA keys when the zero first digit
3696 was met. Affected file lib/silcmath/silcprimegen.c.
3698 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3700 * Fixed WIN32 configuration in the ./configure script.
3701 Fixed to include xti.h on environments that has it.
3702 Patches by Carsten Ilchmann and andrew.
3704 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3706 * Changed the silc_id_create_client_id to be collision
3707 resistant. It is now assured that there cannot be created
3708 two same client ID's. I suspect that some weird bugs in
3709 the server were actually caused by duplicate Client IDs.
3710 Affected file silcd/serverid.[ch]. A router receiving
3711 new ID now also assures and informs the sending server
3712 if the ID caused collision.
3714 * Changed the silc_id_create_channel_id to also assure that
3715 there are no collisions.
3717 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3719 * Statement about ignoring the Mutual Authentication flag when
3720 performing rekey with PFS was a bit misleading. It is ignored
3721 if it was set in the initial negotiation, it cannot be even
3722 set in the rekey. Fixed in the ke-auth draft. Started the
3723 new versions of the protocol drafts in the doc/.
3725 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3727 * Fixed a bug in silc_client_command_identify_save when saving
3728 new channel information. The channel name was no duplicated
3729 and caused crash on exit. Affected file is
3730 lib/silcclient/command_reply.c.
3732 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3734 * Fixed the getkey command handling in the server. Send just
3735 empty OK reply to the sender if the key could not be fetched
3736 (but everything else was ok, like the key just was not available).
3737 Changed the public key parameter to optional in the protocol
3738 specs so that empty OK reply can be sent. Affected file
3741 Added a message to Irssi SILC client to tell to user if the
3742 server did not return a public key.
3744 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3746 * Fixed a channel key regeneration bug. It registered new
3747 timeout tasks exponentially until all system resources were
3748 used. Affected file silcd/server.c.
3750 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3752 * Added the SILC Document generator to the scripts/silcdoc.
3753 It can be used to generate the Toolkit Reference Manual out
3754 of the source tree. Internally it will also use the RoboDoc
3755 generator now imported in util/robodoc.
3757 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3759 * Added couple of return's in rekey protocol if error orccurred
3760 during the protocol. The execution must be terminated.
3761 Affected file silcd/protocol.c. Also, terminate the protocol
3762 always with timeout.
3764 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3766 * The client's Client ID was created initally from the wrong
3767 nickname (it could have been in format nick@host) in the
3768 silc_server_new_client. Affected file silcd/packet_receive.c
3770 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3772 * Added some SILC_LOG_ERROR's to various error conditions
3773 if client could not be added to ID cache. Affected files
3774 silcd/packet_receive.c and silcd/server.c.
3776 * When client's sock->user_data is freed, NULL also the
3777 client->router and client->connection pointers. Added check
3778 for these pointers being NULL to various places around the
3779 code. Affected file silcd/server.c.
3781 * Added client->data.registered == TRUE checks to various
3782 places around the code to assure that unregistered client's
3783 are not handled when it is not allowed. Affected file
3786 * Added `bool registered' fields to all
3787 silc_idlist_[server|client]_get_* routines to indicate whether
3788 the fetched client needs to be registered or not. Affected
3789 file silcd/idlist.[ch].
3791 * Add your own entry as registered to the ID cache in the
3792 server. Affected file server.c.
3794 * Fixed a bug in silc_server_new_server. The SilcServer was
3795 set as the new server's context instead of SilcServerEntry.
3796 This naturally caused some weird bugs.
3798 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3800 * Do not delete the channel rekey task when adding it
3801 for in silc_server_create_channel_key.
3803 * Changed the silc_server_create_channel_key to return
3804 TRUE or FALSE to indicate the success of the channel key
3807 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3809 * Fixed MSVC++ project files and added missing files to
3810 Makefiles under win32/.
3812 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3814 * Do not add TCP_NODELAY flag if the operating system
3815 does not have it defined. Affected files are
3816 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3818 * Fixed buffer overflow from Irssi SILC Client. Affected
3819 file irssi/src/fe-common/core/themes.c.
3821 * Fixed double free in client library in the file
3822 lib/silcclient/client.c when disconnecting from server.
3824 * Applied double free patch from cras to Irssi SILC client.
3825 Affected files irssi/src/core/[modules/expandos].c
3827 * Fixed the disconnection handling to Irssi SILC Client.
3828 The application must call silc_client_close_connection
3829 in ops->connect client operation in case of failure of
3830 the connection. Affected file is
3831 irssi/src/silc/core/client_ops.c.
3833 * Do not set sock->protocol to NULL in the function
3834 silc_client_close_connection after executing the protocol's
3835 final callback since the sock might not be valid anymore.
3836 Affected file lib/silcclient/client.c.
3838 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3840 * Do not enable SILC_THREADS if the linking with libpthread
3841 did not happen. Affected file configure.in.pre.
3843 * Added notion to protocol specification that server must
3844 verify the sent authentication payload with CMODE when
3845 setting the channel founder key. Implemented it to the
3846 server. Affected file silcd/command.c.
3848 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3850 * Added _EXTRA_DIST SILC distribution variable to the
3851 distributions file. It is used to conditionally add extra
3852 files or directories to the specific distribution. Affected
3853 files ./prepare, Makefile.am.pre and distributions.
3855 Removed the `_' from the start of the distribution names.
3858 * Added README.WIN32 for instructions to compile the Toolkit
3861 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3863 * Fixed a double free in disconnection in the server. Affected
3864 file is silcd/server.c.
3866 * Fixed the lib/silcske/groups.c to work now also with GMP
3867 MP library. The string conversion did not work when using
3868 specific base and the base is indicated in the string as well.
3870 * Created win32/ directory which now includes MSVC++ specific
3871 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3872 It will appear only in the toolkit distribution
3874 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3876 * Changed the key material distribution function in case when
3877 the hash output is too short. The data is now concatenated
3878 a bit differently than it used to. Made the change to the
3879 SKE protocol specification.
3881 * Added better GMP detection to configure.in.pre. A patch
3884 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3886 * Fixed a minor bug in SKE that might cause some problem on
3887 some platforms. Affected file lib/silcske/silcske.c.
3889 * Added the cookie checking for initiator in the SKE. It checks
3890 that the responder returns the sent cookie unmodified. The
3891 affected file is lib/silcske/silcske.c. Added new SKE
3892 error type INVALID_COOKIE that can be sent during the
3893 negotiation. Fixed some memory leaks as well.
3895 * Added the "invalid cookie" error message to Irssi SILC client's
3898 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3900 * Added `task_max' field to the SilcClientParams to indicate
3901 the maximum tasks the scheduler can handle. If set to zero,
3902 default values are used. Affected file lib/silcclient/silcapi.h.
3904 * Fixed memory leaks in silc_client_close_connection. Affected
3905 file lib/silcclient/client.c.
3907 * Added silc_client_del_client_entry to client library to free
3908 all memory of given client entry. Affected file is
3909 lib/silcclient/idlist.[ch].
3911 * Added new functions silc_client_del_channel and
3912 silc_client_del_server to delete channel and server entries.
3913 Affected file lib/silcclient/[silcapi.h/idlist.c].
3915 * Removed silc_client_del_client_by_id from silcapi.h.
3917 * Fixed the INFO command to return the server's own info
3918 correctly when querying by Server ID. Affected file is
3921 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3923 * Removed the non-blocking settings in WIN32 code in the
3924 silc_sock_[read/write] and added SleepEx instead. Affected
3925 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3926 of input data is now checked with FIONREAD and ioctlsocket.
3928 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3930 * Call silc_schedule_task_del_by_context in the
3931 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3932 Affected file lib/silccore/silcprotocol.c.
3934 * Call silc_protocol_cancel for active protocols in the
3935 silc_server_close_connection if the funtion
3936 silc_server_free_sock_user_data has not been called.
3937 Affected file silcd/server.c.
3939 * Generic tasks cannot be deleted using the del_by_fd
3940 task deleting function since generic tasks does not match
3941 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3943 * Added a notion to SILCOPER help file that the SILCOPER works
3944 only on router server, not on normal server.
3946 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3948 * Added for WIN32 support for the new scheduler as well.
3949 Affected file lib/silcutil/win32/silcwin32schedule.c.
3951 * Fixed the SHA1 implementation to work on various platforms.
3953 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3955 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3956 API. It is part of the scheduler now. Everything else is
3957 as previously but some functions has changed their names.
3958 Checkout the lib/silcutil/silcschedule.h for the interface.
3959 Updated all applications to use the new interface. Affected
3960 files are lib/silcutil/silcschedule.[ch].
3962 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3964 * Found a bug in the SKE implementation. The HASH value,
3965 specified by the protocol, was not computed correctly. The
3966 public key of the responder was not added to the computation
3967 even though it is mandatory. Affected file lib/silcske/silcske.c.
3968 This unfortunately causes incompatibilities with older
3969 clients and servers.
3971 * Added WIN32 specific network init and uninit functions:
3972 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3973 the Winsock2. Affected file lib/silcutil/silcnet.h and
3974 lib/silcutil/win32/silcwin32net.c.
3976 * Set the socket always to nonblocking mode on WIN32 after
3977 reading data or writing data. Affected file is
3978 lib/silcutil/win32/silcwin32sockconn.c.
3980 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3982 * Fixed various compilation problems under WIN32. Affected
3983 files lib/silcutil/win32/silcwin32thread.c and
3984 lib/silcutil/win32/silcwin32schedule.c.
3986 * Removed all _internal.h #includes from public header
3987 files. Internal headers must never be included from
3990 Removed also the lib/silcske/payload_internal.h file.
3992 * All include files that may be needed (public and some others
3993 included by the public headers) by application developers are
3994 now copied to the ./includes directory. It does not copy any
3995 internal headers. Affected file Makefile.defines.pre and all
3996 Makefile.am's under lib/ and subdirs.
3998 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4000 * Do not change the ~/.silc directory's permissions automatically.
4001 Affected file irssi/src/silc/core/clientutil.c.
4003 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4005 * Do not cancel the protocol in silc_server_close_connection
4006 it might cause recursion. Now cancelled in the function
4007 silc_server_free_sock_user_data. Affected file silcd/server.c.
4009 * Fixed the silc_server_remove_clients_by_server to regenerate
4010 the channel keys correctly finally. Added also new function
4011 silc_server_remove_clients_channels to actually do it.
4012 Affected file silcd/server.c.
4014 * Fixed the silc_server_new_channel to not crash by giving
4015 wrong router to the new channel. Affected file is
4016 silcd/packet_receive.c.
4018 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4020 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
4021 which is given as argument to the silc_client_alloc now.
4022 It can be used to configure the client and set various parameters
4023 that affect the function of the client.
4025 * The USERS command in server did not check whether the channel
4026 is private or secret. Affected file silcd/command.c.
4028 * Added new argument to the USERS command in protocol specification.
4029 The USERS command now can take the channel name as argument
4030 as well. Added support for this in client and server and
4031 updated the protocol specs.
4033 * Completed the GETKEY command in client. It can be now used
4034 to fetch also servers public key not only some clients.
4035 Affected files lib/silcclient/command[_reply].c.
4037 * Added silc_client_get_server to return server entry by the
4038 server name. Affected files lib/silcclient/silcapi.h and
4041 * Redefined the IDENTIFY command in protocol specification to be
4042 more generic. It now can be used to query information about
4043 any entity in the SILC Network, including clients, servers and
4044 channels. The query may be based either the entity's name
4045 or the ID. Added support for this in both client and server.
4047 Affected files silcd/command.c and lib/silcclient/command.c
4048 and command_reply.c.
4050 * Optimized the WHOIS and WHOWAS commands in the server. Removed
4051 the _from_client and _from_server functions. Affected file
4054 * Added silc_client_get_channel_by_id_resolve to the file
4055 lib/silcclient/silcapi.h to resolve channel information by
4056 its ID. Added also silc_client_get_channel_by_id that
4057 does not resolve it from the server.
4059 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4061 * Added SilcServerEntry context into the client library
4062 to represent one server. The INFO command now allocates
4063 these to save the resolved server info. For now on the
4064 client library will also keep information about servers,
4065 connected and resolved with INFO.
4067 The INFO command now allocates the SilcServerEntry context
4068 and saves the server info there. The COMMAND_REPLY in
4069 the INFO now returns the parameters to application in
4070 same order as defined in the protocol specification.
4072 The entries are cached in the client->server_cache.
4074 * The INFO command is now issued after received the Client ID
4075 from the server. Affected file lib/silcclient/client.c.
4077 * The CMODE_CHANGE notify may now return also an SilcServerEntry
4078 to the application as the mode changer might be server.
4079 It is guaranteed that NULL is not returned anymore to the
4080 application. Affected file lib/silcclient/client_notify.c.
4082 The ID Type is now also passed to the application so that
4083 it can check whether the returned entry is SilcClientEntry
4086 Added new function silc_client_get_server_by_id to return
4087 the server entry by ID. Affected files are the
4088 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
4090 * Do not create the channel in the Irssi SILC Client when issuing
4091 the JOIN command but when received the sucessful JOIN command
4092 reply. Otherwise the channel might get created even though we
4093 could not join it. The Affected file is
4094 irssi/src/silc/core/[silc-channels.c/client_ops.c].
4096 * Fixed a channel joining bug in router. The router must also
4097 check the channel modes, invite and ban lists etc. when serving
4098 the JOIN command sent by normal server. Affected file is
4099 silcd/command.c. The router now resolves the client's
4100 information from the server who sent the JOIN command if it
4101 does not know it, and processes the JOIN command only after
4104 * Changed the SilcCommandCb to take new argument; void *context2.
4105 Affected file lib/silccore/silccommand.h
4107 The second argument in the command callbacks in the server now
4108 includes the SilcServerCommandReplyContext if the command was
4109 called as pending command callback from the command reply.
4110 Otherwise it is NULL. When called as pending the status of the
4111 command reply will be checked and if it was erronous the
4112 error will be sent to the original sender of the command.
4113 This way the client always receives the error messages even
4114 though the server was actually the one who received the error
4115 when it resent the command to router, for example. Affected
4116 files silcd/command[_reply].[ch].
4118 * Fixed sending WHOWAS command's error message to client if
4119 the requested client could not be found. It was missing.
4122 * Changed the CMODE and CUMODE commands reply arguments in the
4123 protocol specification. The Channel ID is now sent in both
4124 of the commands to identify the channel. Implemented this
4125 new feature to the client and server. Affected files
4126 lib/silcclient/command_reply.c and silcd/command.c.
4128 * Made better checks for invite and ban lists in the JOIN
4129 command in server. Affected file silcd/command.c.
4131 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4133 * The server now performs the incoming host IP/DNS lookup
4134 using the silc_socket_host_lookup and thus does not block
4135 the server anymore. Affected file silcd/server.c.
4137 * Completed the multi-thread support for SILC Scheduler in
4138 the lib/silcutil/silcschedule.c.
4140 * Fixed the configure.in.pre to detect the pthread correctly
4143 * Fixed a deadlock in silc_task_queue_wakeup in the file
4144 lib/silcutil/silctask.c.
4146 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4148 * Added new function silc_schedule_wakeup that is used in
4149 multi-threaded environment to wakeup the main thread's
4150 schduler. It needs to be used when a thread adds a new task
4151 or removes a task from task queues. After waking up, the
4152 scheduler will detect the task queue changes. If threads
4153 support is not compiled in this function has no effect.
4154 Implemented the wakeup mechanism to both Unix and WIN32
4155 systems. Affected files are lib/silcutil/silcschedule.[ch],
4156 lib/silcutil/unix/silcunixschedule.c and the
4157 lib/silcutil/win32/silcwin32schedule.c.
4159 * Added new function silc_task_queue_wakeup to wakeup the
4160 scheduler by the specified task queue. Affected file
4161 lib/silcutil/silctask.[ch].
4163 * The silc_socket_host_lookup_start now wakes up the scheduler
4164 after adding the timeout task. Affected file is
4165 lib/silcutil/silcsockconn.c.
4167 * The silc_socket_host_lookup is synchronous now if the threads
4168 support is not compiled in. However, the callback is still
4169 called asyncronously through the scheduler, anyway. Affected
4170 file lib/silcutil/silcsockconn.c.
4172 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4174 * Added new function silc_socket_host_lookup to perform
4175 asynchronous IP and FQDN lookups for the socket connection.
4176 Affected files lib/silcutil/silcsockconn.[ch].
4178 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4180 * Added SILC_MUTEX_DEFINE to define the mutex on environments
4181 that may or may not compile the mutex support in.
4183 Changed the silc_mutex_alloc interface. It allocates the
4184 mutex now to the sent pointer and returns TRUE or FALSE.
4186 Affected file lib/silcutil/silcmutex.h.
4188 * Wrote the SILC Task Queue interface to support multi-threads.
4189 Affected file lib/silcutil/silctask.[ch].
4191 * Wrote the SILC Scheduler to support multi-threads. Affected
4192 file lib/silcutil/silcschedule.c.
4194 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4196 * Implemented the SILC Mutex API and SILC Thread API for WIN32
4197 in lib/silcutil/win32/.
4199 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4201 * Defined SILC Mutex API and SILC Thread API and implemented
4202 them for Unix. Affected files are
4203 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
4204 lib/silcutil/unix/silcunixmutex.c and
4205 lib/silcutil/unix/silcunixthread.c.
4207 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4209 * Fixed the silc_server_remove_clients_by_server's channel
4210 key re-generation. The hash table handling was incorrect
4211 and would not work with many channels. Affected file is
4214 * Fixed some memory leaks around the server code.
4216 * Rewrote the silc_server_get_users_on_channel to support IPv6
4217 based Client ID's. Affected file silcd/server.c.
4219 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
4220 specification. However, a separate document must be written
4221 to define the detailed signing procedure and the payload
4222 associated with the flag. Defined the flag to the
4223 lib/silccore/silcchannel.h as well.
4225 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4227 * Changed the dynamic tables to static size tables in the
4228 lib/silccrypt/silchmac.c.
4230 * Removed GCC dependencies from the code. A patch by cras.
4232 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4234 * Do not show the error "Error receiving packet bla bla"
4235 in server if it really was not an error (-2 means that reading
4236 is pending). Affected file silcd/server.c.
4238 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4240 * Fixed a possible crash in silc_server_remove_clients_by_server
4241 in silcd/server.c. Fixed there also some memory leaks.
4243 * Fixed the silc_idlist_replace_client_id. It could replace
4244 wrong key in the hash table. Affected file silcd/idlist.c.
4246 * Do not check whether there are global users on the channel
4247 if the channel->global_users is FALSE. Affected functions
4248 silc_server_remove_from_one_channel and
4249 silc_server_remove_from_channels in silcd/server.c. Also,
4250 do not check if the removed client is local as we can be
4251 sure that global client was not removed from the channel
4252 and checking for global users is not needed.
4254 * The silc_server_remove_clients_by_server now re-generates
4255 the channel keys correctly for those channels that had
4256 clients removed from them. Affected file silcd/server.c.
4258 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4260 * Found the reason of random crashes in the server. We weren't
4261 ignoring the SIGPIPE signal (which can be sent in write())
4262 and it crashed the server. Affected file silcd/silcd.c.
4264 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4266 * Assure that sock->user_data is not NULL in the function
4267 silc_server_packet_send in silcd/packet_send.c.
4269 * Disconnect the remote connection if it could not be added
4270 to any ID lists in the server. The affected file is
4273 * Check in silc_server_packet_send[_real/dest] that the
4274 socket is not disconnecting and ignore the data if it is.
4275 Affected file silcd/packet_send.c.
4277 * Define inline to __inline on native WIN32 compilation.
4278 Affected file includes/silcwin32.h.
4280 * Added some explicit type casts for inline code since MSVC
4281 require them. Affected files lib/silcutil/silcbuffer.h,
4282 lib/trq/silcdlist.h and lib/trq/silclist.h.
4284 * Print warning in log files from now on if the packet
4285 decryption fails. Affected file silcd/server.c.
4287 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4289 * Changed the `say' client operation's interface to accept
4290 new `type' argument to indicate the type of the message sent
4291 by the library. The application may filter the library's
4292 messages according the type. The affected file is the
4293 lib/silcclient/silcapi.h.
4295 * Added two new functions to lib/silcclient/silcapi.h:
4296 silc_client_del_client and silc_client_del_client_by_id.
4297 Affected file lib/silcclient/idlist.c.
4299 * Moved the clientincludes.h from includes/ to silc/ and
4300 serverincludes.h from includes/ to silcd/.
4302 * The modes for the CMODE and CUMODE are now passed as
4303 uint32 for application with COMMAND_REPLY. The affected
4304 file is lib/silcclient/command_reply.c.
4306 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4308 * /WHOIS without arguments shows client's own information.
4309 Affected file lib/silcclient/command.c.
4311 * Changed PING to not accept any arguments. The specs
4312 says that client can ping only the connected server so
4313 requiring an argument is not needed. Affected file is
4314 lib/silcclient/command.c.
4316 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4318 * Fixed a fatal bug in private message sending and reception
4319 encryption and decryption when using private message keys.
4320 The implementation was incorrect and did not follow the
4321 specification. It causd that some of the message were
4322 lost since it did not use the sending and receiving keys
4323 as the protocol suggests. This has been fixed and will cause
4324 incompatibilities with older clients when sending private
4325 message encrypted with private message keys. Affected files
4326 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
4327 and various other in Irssi SILC Client.
4329 Added `responder' boolean argument to the functions
4330 silc_client_add_private_message_key[_ske] to indicate when
4331 the key is added as responder or initiator of the key
4334 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4336 * Removed the silc_ske_check_version function and created
4337 a SilcSKECheckVersion callback. Added also a function
4338 silc_ske_set_callbacks that is now used to set all SKE
4339 callbacks. The callback functions are not given to
4340 the SKE functions anymore, but this function is used to
4343 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
4345 * Added `silc_version' argument to the silc_client_alloc
4346 to define the version of the application for the library.
4347 The library will use the version string to compare it
4348 against the remote host's (usually a server) version
4349 string. Affected file lib/silcclient/silcapi.h
4351 * Added the KE protocol context to Key Agreement context
4352 in client library so that we can abort the SKE if it
4353 is in process when we get timeout. Affected file is
4354 lib/silcclient/client_keyagr.c.
4356 * Do not resolve the client ID forever if it returns in the
4357 first time that such client does not exist. This was done
4358 for example with private message. Affected file is
4359 lib/silcclient/client_prvmsg.c.
4361 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4363 * Do not add regex.h for WIN32. The affected file
4364 includes/silcincludes.h.
4366 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
4367 not work yet 100%. It generates the DLL's automatically
4368 when compiling with --with-win32 under cygwin.
4370 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4372 * lib/contrib/regex.c is not compiled on WIN32.
4374 * Added silc_net_get_socket_opt function to the
4375 lib/silcutil/silcnet.h.
4377 * Added includes/silcwin32.h for WIN32 specific includes
4380 * Do not use ptime structure or any of the posix process
4381 functions on WIN32 in lib/silccrypt/silrng.c.
4383 * Added silc_gettimeofday to provide generic function
4384 for struct timeval on all platforms. Added the function
4385 to lib/silcutil/silcutil.h.
4387 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4389 * Moved the lib/silccore/silcsockconn.[ch] to the utility
4390 library as they clearly belong there. As a plus side we
4391 can make the actual socket connection routines platform
4394 Added also new generic function silc_socket_read and
4395 silc_socket_write (that used to be silc_packet_[read/write].
4396 The implementation of these are platform specific.
4398 * Added WIN32 specific routines of silc_socket_[read/write]
4399 to lib/silcutil/win32/silcwin32sockconn.c.
4401 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4403 * Added preliminary support for native WIN32 compilation under
4404 cygwin (using the -mno-cygwin option for GCC) to the
4405 ./configure.in.pre. The --with-win32 now prepares the
4406 compilation for native WIN32.
4408 * Rewrote the SILC Scheduler interface in the file
4409 lib/silcutil/silcschedule.h. The scheduler is now context
4410 based and does not have anymore any global static scheduler.
4411 Moved the Unix scheduler to the lib/silcutil/unix/ directory
4412 and created lib/silcutil/win32 directory for WIN32 based
4415 * Added Unix specific network routines to the
4416 lib/silcutil/unix/silcunixnet.c and the old
4417 lib/silcutil/silcnet.c includes now only generic routines.
4419 Added WIN32 specific network routines to the
4420 lib/silcutil/win32/silcwin32net.c.
4422 * Added Unix specific utility functions from the
4423 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
4425 * Added WIN32 SILC Scheduler to the file
4426 lib/silcutil/win32/silcwin32schedule.c. The code is of course
4429 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4431 * Do not handle JOIN notify in the server if the target client
4432 is not registered (idata->registered == FALSE). The affected
4433 file is silcd/packet_receive.c.
4435 * Update the nickrec->founder in event_cumode in the Irssi SILC
4436 client. Affected file irssi/src/silc/core/silc-channels.c.
4438 * Fixed the CUMODE_CHANGE notify handling in the server when
4439 server and router are announcing their clients on channels.
4440 Now the mode changes are saved and notified correctly. The
4441 affected file is /silcd/packet_receive.c.
4443 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
4444 They really did not replace the cache entry in the ID Cache.
4445 Now they do that. Affected file silcd/idlist.c.
4447 * Fixed the KICK notify handling in the Irssi SILC client to
4448 update the channel records so that the kicked client does not
4449 appear to be on the channel. The affected file is
4450 irssi/src/silc/core/silc-channels.c.
4452 * Always update the conn->current_channel when executing command
4453 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
4455 * Fixed the KILL notify handling in Irssi SILC client to remove
4456 the killed client on all channels.
4458 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4460 * Fixed the silc_parse_command_line to remove extra spaces
4461 from the start and end of the arguments. Affected file is
4462 lib/silcutil/silcutil.c.
4464 * Cancel and free any active protocol in the function
4465 silc_server_close_connection. Affected file silcd/server.c.
4467 * Cancel and free any active protocol in the function
4468 silc_client_close_connction. Affected file is
4469 lib/silcclient/client.c.
4471 * Do not execute the KILL command for clients that are in
4472 history (ie. they are not in the network). Affected file is
4475 * Fixed KILL notify handling, client does not crash anymore.
4476 Affected file irssi/src/silc/core/silc-channels.c.
4478 * Reduced the default packet buffer size from 2048 to 1024 in
4479 lib/silccore/silcpacket.c.
4481 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
4482 counter to the SKE context that is incresed when the SKE library
4483 performs async operation outside the library. If the outside
4484 process frees the SKE context and FREED status will be set
4485 and the library will detect after the sync operation that the
4486 libary is freed. The affected files are
4487 lib/silcske/silcske[_status].[ch].
4489 * Resolve the client entry information in the function
4490 silc_client_channel_message to assure that NULL pointer is not
4491 passed as client entry to the application. */
4493 * Fixed the task timeout calculation to assure that there is
4494 never negative timeouts. The affected file is
4495 lib/silcutil/silcschedule.c.
4497 * Fixed the channel user mode notification sending in server.
4498 It was sent point-to-point to the router (or to server by router)
4499 but it needs to be destined to a channel. The routines now
4500 supports sending the channel user mode notifys to the channels
4501 when announcing clients and channels. Affected files are
4502 silcd/server.c and silcd/packet_receive.c.
4504 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
4505 It did not actually replace the old channel entry in the cache.
4506 Affected file lib/silcclient/client_notify.c.
4508 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4510 * Fixed a possible crash in silc_packet_send_prepare. It now
4511 assures always that there is enough space in the buffer and
4512 at the tail area of the buffer (for MAC).
4514 Fixed the inbound buffer reallocation in silc_packet_read.
4515 It was old code and did not handle the reallocation correctly.
4518 The affected file is lib/silccore/silcpacket.c.
4520 * Fixed buffer overflow in silc_parse_nickname in the file
4521 lib/silcutil/silcutil.c.
4523 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4525 * make install generates new server keys only if there is not
4528 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4530 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
4531 Added check that if the NOREPLY is set then we will not send
4532 the away message. This avoids infinite loop of away messages
4533 if both clients are away. The affected file is
4534 lib/silcclient/client_prvmsg.c.
4536 * Fixed client crash if /NICK was given without arguments.
4537 Affected file lib/silcclient/command.c.
4539 * Server does not send the invite list in INVITE command back
4540 to the client if the list was not altered. Added this notion
4541 to the protocol spec as well. Affected file silcd/command.c.
4543 Fixed possible crash in INVITE command by checking the
4544 value of silc_server_get_client_route command.
4546 * Fixed the INVITE notify type handling. The arguments are now
4547 taken in correct order and client does not crash. The affected
4548 file is irssi/src/silc/core/silc-channels.c.
4550 Removed the "Inviting xxx to channel" message from the
4551 client library away and let the application handle it.
4552 Affected file lib/silcclient/command.c. Added that message
4553 to Irssi SILC client's message formats.
4555 * Fixed CMODE command crash in client. It now checks the
4556 amount of arguments correctly and does not crash. The affected
4557 file is lib/silcclient/command.c.
4559 * Do not create new channel automatically in silc_channels_join
4560 but check whether the channel by that name already exists.
4561 Affected file irssi/silc/core/silc-channels.c.
4563 * Do not send the SERVER_SIGNOFF to router if the disconnected
4564 entity was the router. Affected file silcd/server.c.
4566 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
4567 SILC client as it was missing from there.
4569 Added the handling of the KICK notify to the Irssi SILC client
4570 as it was missing. Added "you have been kicked" message to
4571 Irssi SILC client's message modules formats.
4573 Added the handing of the KILL notify to the Irssi SILC client
4574 as it was missing. Added the kill message module formats
4577 The affected file is irssi/src/silc/core/silc-channels.c.
4579 * The router did not save the channel mode the server announced.
4580 Affected file silcd/packet_receive.c.
4582 * Fixed a possible crash in INFO command in server. If the
4583 server did not provide the server info it crashed. Affected
4584 file silcd/command.c.
4586 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4588 * Fixed the GETKEY command in the server to check also the
4589 global list. Otherwise the GETKEY would not work correctly
4590 in normal SILC server. Affected file silcd/command.c.
4592 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4594 * Fixed GETKEY crash, it crashed if the command did not succseed.
4596 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4598 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
4599 is now real and not just an macro interface to GMP.
4601 Removed the entire GMP from the source tree and imported new
4602 NSS MPI library instead. Reason for removing GMP is that it is
4603 extremely large and compiles extremely slow. The NSS MPI
4604 is only a few files and compiles in less than 10 seconds.
4605 The speed is also about the same as GMP. The MPI is imported
4606 to lib/silcmath/mpi.
4608 If the system has GMP installed we will still use the GMP.
4609 If it is not then the NSS MPI will be compiled.
4611 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4613 * Merged a long nickname (127 characters long) crash bugfix from
4614 Irssi CVS tree. Affected file irssi/src/core/misc.c.
4616 * Merged a freed memory reference bugfix from Irssi CVS tree.
4617 Affected file irssi/src/core/commands.c.
4619 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4621 * Added the server's public key sving and verification to the
4622 server when performing the SKE. This was missing and the
4623 remote server's (or router's) public key was accepted without
4624 checking whether we have it previously or trust it at all.
4625 Affected file silcd/protocol.c.
4627 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4629 * Check in the silc_server_timeout_remote if protocol is active
4630 and make sure that the protocol's final callback is called so
4631 that all memory if freed. Affected file silcd/server.c.
4633 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4635 * silc_server_whois_send_reply crashed the server if the nickname
4636 was 127 characters long. Affected file silcd/command.c.
4638 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4640 * Added sanity check to the silc_server_new_client. If the hostname
4641 is provided inside username then check that the provided hostname
4642 really is the same as the resolved one. If the hostname was not
4643 resolved then check it from the public key. Affected file is
4644 silcd/packet_receive.c.
4646 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
4647 if the server disconnected us and the connection is not valid
4648 anymore. Affected file irssi/src/silc/core/silc-channels.c.
4650 * Moved the silc_client_[chmode|chumode|chumode_char] away from
4651 the library to the lib/silcutil/silcutil.[ch].
4653 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4655 * Close log file after open. Affected file
4656 lib/silcutil/silclog.c.
4658 * Check whether sock == NULL in silc_client_send_packet and return
4659 if it is. Affected file lib/silcclient/silcclient.c.
4661 * Check rec->entry == NULL in the Irssi SILC Client before
4662 sending the channel message. Affecte file is
4663 irssi/src/silc/core/silc-servers.c.
4665 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4667 * Merged a splitted window bugfix from Irssi CVS tree. The
4668 affected file is irssi/src/fe-text/textbuffer-view.c.
4670 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
4671 It did not print nickname.
4673 * Improved the distributions system a bit.
4675 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4677 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
4678 irssi/src/fe-text/gui-window.c.
4680 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
4681 to in-active server. The affected file is
4682 irssi/src/silc/core/client_ops.c.
4684 * Resolve the client in USERS command reply if the entry does
4685 not have username resolved. The affected file is
4686 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
4687 command to WHOIS command to really resolve stuff. The USERS
4688 is not used any more in any critical section so WHOIS can
4689 be used even though it might be slower than IDENTIFY.
4691 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
4694 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4696 * Changed the protocol API a bit more consistent in the
4697 lib/silccore/silcprotocol.[ch].
4699 * Changed the following headers to ROBODoc format:
4701 lib/silccore/silcpayload.h
4702 lib/silccore/silcprotocol.h
4703 lib/silccore/silcsockconn.h
4705 All core library headers are now formatted.
4707 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4709 * Fixed a bug in Irssi SILC client; do not show that you are
4710 server/router operator if you really are not. Affected file is
4711 irssi/src/silc/core/client_ops.c.
4713 * Renamed silc_command_free_payload to silc_command_payload_free.
4714 Affected file lib/silccore/silccommand.h
4716 * Added silcmath.h to include the prototoypes of various routines
4717 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
4720 * Changed the following headers to ROBODoc format:
4722 lib/silccore/silcchannel.h
4723 lib/silccore/silccommand.h
4724 lib/silccore/silcid.h
4725 lib/silccore/silcidcache.h
4726 lib/silccore/silcmode.h
4727 lib/silccore/silcnotify.h
4728 lib/silccore/silcpacket.h
4729 lib/silcmath/silcmath.h
4731 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4733 * Added checking to the server code not to start the server if
4734 ciphers and stuff are not configured properly. Affected files
4735 silcd/serverconfig.[h] and silcd/server.c.
4737 * Changed the layout of the header files of the public interfaces
4738 in the SILC libraries. The new layout supports ROBODoc
4739 documentation tool (and some others) so that it is easy to create
4740 a library reference manual. All the other headers and source
4741 code must still follow the CodingStyle document. Also source
4742 code must not include these ROBODoc stuffs, only the headers.
4743 Furthermore, all public interface headers must now be named
4744 by using `silc' prefix, example: silcapi.h, silccipher.h.
4745 Some files were renamed due to this. All the other headers
4746 must not be used as public interfaces. I will update the
4747 CodingStyle document later. Changed following headers, so far:
4749 lib/silcclient/silcapi.h
4750 lib/silccore/silcauth.h
4751 lib/silccore/silcprivate.h
4752 lib/silccrypt/silcdh.h
4754 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4758 * Removed silc_client_packet_send_flush from the client library
4759 as it is not needed. Affected file lib/silcclient/client.[ch].
4761 * Added printing of message of unresolved authentication method
4762 to the Irssi SILC client. Added it to the module formats.
4763 Removed the same message from the client library.
4765 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4767 * Added new distribution feature, DISTLABEL. Every distribution
4768 can define own preprocessor label that can be used in the
4769 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
4770 file distributions, acconfig.h.pre and prepare.
4772 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4774 * Added Makefile.defines_int to include the actual definitions
4775 for Makefile.defines.in. Tested the new distribution system,
4776 created distributions and tested installation.
4778 * Added AWAY message printing to the Irssi SILC client. Added
4779 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
4781 * Added SCONNECT command to call the SILC's CONNECT command.
4782 Cannot use CONNECT directly since Irssi uses that internally.
4783 Affected file irssi/src/silc/core/silc-servers.c.
4785 Added ACTION local command. It is same as ME command but takes
4786 the channel as mandatory argument.
4788 Rewrote some of the Irssi's help files to suite for SILC
4791 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4793 * Added Makefile.defines[.in] that should for now on be included
4794 in all Makefile.am file in the source tree. That file includes
4795 all common compilation definitions for SILC source tree.
4797 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4799 * Minor changes to the ./prepare script to change the package
4800 name according the distribution name to the configure.in.
4802 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4804 * Created new distribution system. Added file `distributions'
4805 that defines all the distributions that can be created out of
4806 the SILC source tree. The ./prepare script now reads that
4807 file to determine how to prepare the distributions. The
4808 first argument to the ./prepare is the name of the distribution
4809 and second is the version of the distribution. If given
4810 without arguments it creates the default (toolkit) distribution
4811 with the default version (defined in ./prepare).
4813 All Makefile.am files that are subject to the distributions
4814 are now named as Makefile.am.pre. These are ./Makefile.am
4815 and lib/Makefile.am. Others may be changed later.
4817 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4819 * Added invite list, ban list, some key management and connection
4820 error message printing to module formats in the Irssi SILC client.
4822 * Added new silc_client_set_away_message to set the away message
4823 that is back to the person who sent private message. The
4824 affected file lib/silcclient/silcapi.h and the
4825 lib/silcclient/client_prvmsg.c.
4827 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4829 * Fixed the private message sending in the Irssi SILC client,
4830 added local command KEY to the Irssi SILC client.
4832 Added key management and key agreement message formats to the
4833 irssi/src/fe-common/silc/module-formats.[ch].
4835 Added USERS (alias WHO) printing, server/router operator
4836 indication and LIST command printing to the module formats.
4838 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4840 * Fixed channel joining notify handling, cumode notify handling
4841 from Irssi SILC client.
4843 * Added SILC specific module-formats to the Irssi SILC client so
4844 that SILC specific message hilighting, colors etc is possible.
4845 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4847 Added channel mode, channel user mode, actions, notices,
4848 whois and whowas printing to the the module-formats.c.
4850 * Fixed a bug in channel deletion in the server. The channel
4851 is not left to the cache even if the channel founder auth mode
4852 is set when there are no users anymore on the channel. Affected
4853 file silcd/server.c.
4855 * The silc_net_localhost now resolves the entire hostname including
4856 the domain name. Affected file lib/silcutil/silcnet.c.
4858 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4860 * Changed the ask_passphrase client operation to be ascynchronous.
4861 It has now a completion callback and a context that the
4862 application must call after it has got the passphrase from
4863 the user. Affected files lib/silcclient/silcapi.h,
4864 lib/silcclient/protocol.c, lib/silcclient/command.c and
4867 Added SilcAskPassphrase callback that the application calls
4868 to deliver the passphrase to the library.
4870 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4871 The public key verification and especially a certificate
4872 verification is asynchronous procedure.
4874 Added new SILC_SKE_STATUS_PENDING status to indicate the
4875 request is pending and a callback will be called to finalize
4878 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4879 indicate that remote end did not send its public key (or
4880 certificate), even though we require it. Added check for this
4881 condition in the SKE. This was a security bug, now fixed.
4883 Defined new SilcSKEVerifyCbCompletion callback that is called
4884 when the verification process is completed.
4886 The affected files lib/silcske/silcske_status.h and
4887 lib/silcske/silcske.[ch].
4889 * Changed the verify_public_key client operation to be async
4890 as well. Defined SilcVerifyPublicKey callback that is used to
4891 indicate the success of the public key verification process.
4893 Changed the server and client to use the new async client
4896 * Changed the Irssi SILC client's internal scheduler to be called
4897 twice as many times as it used to be. As a result the client
4898 should be a bit faster now. Affected file is
4899 irssi/src/silc/core/silc-core.c.
4901 * Added support to Irssi SILC client of asynchronous public key
4902 verification and passphrase inquiry. Affected file is
4903 irssi/src/silc/core/silc-core.c.
4905 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4907 * Do not say "You have left channel %s" in client library.
4908 Moved it to the application. Affected files are
4909 lib/silcclient/command.c and silc/client_ops.c.
4911 * Fixed silc_client_get_clients. Command context was not
4912 duplicated and was freed memory in the callback. Affected
4913 file lib/silcclient/idlist.c.
4915 * Do not say "you are now talking..." on JOIN command in the
4916 client library. The appliation must handle it.
4918 * Do not say ".. changed topic to" in command reply in the
4919 client libary. The application must handle it.
4921 * Fixed TOPIC command sending in the client library.
4923 * Fixed a memory leak in silc_client_command_free in the file
4924 lib/silcclient/command.c.
4926 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4928 * Imported a modified version of Irssi client to the source tree.
4929 The Irssi will be used to create a new client called
4930 Irssi SILC. Imported to irssi/.
4932 Added silc_core_init_finish function to the Irssi. Affected
4933 file irssi/configure.in.
4935 A lot changes in the Makefile.ams around the irssi tree.
4937 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4939 * Do not rehash if the new size is same as the old size of the
4940 hash table, in the silc_hash_table_rehash*. The affected file
4941 lib/silcutil/silchashtable.c.
4943 * Replaced hash_table_del_by_context calls from the server
4944 (when channel->user_list and client->channels) to the
4945 hash_table_del as it is sufficient and faster.
4947 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4949 * Added silc_hash_table_list, silc_hash_table_get and the
4950 SilcHashTableList structure to provide an alternative way to
4951 traverse the hash table. The affected files are
4952 lib/silcutil/silchashtable.[ch].
4954 * Changed the server's idlist routines to use the hash table
4955 routines to optimize the code.
4957 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4959 * Replaced the client entry's `channel' list and channel entry's
4960 `user_list' list to hash tables for optimized lookup. Changed
4961 the code to use the hash table interface around the code.
4962 Affected file lib/silcd/idlist.[ch].
4964 * Added `auto_rehash' boolean argument to the function
4965 silc_hash_table_alloc to indicate whether the hash table should
4966 auto-rehash when it thinks is appropriate time. It will
4967 increase the hash table size if the there is twice as much
4968 entries in the table than the size of the table, and will
4969 decrease the size if there are twice as less entries than
4970 the size of the table.
4972 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4974 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4976 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4978 * silc_idcache_purge_by_context deletes the entry now by context
4979 as it is supposed to do. Affected file lib/silccore/idcache.c.
4981 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4982 client is not anymore valid (WHOWAS givens the info) and not
4983 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4985 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4987 * Removed the `data' and `data_len' arguments from the ID Cache
4988 interfaces and added `name' argument. ID Cache does not handle
4989 anymore the binary data only a names associated with given ID.
4991 * When hashing a Client ID with silc_hash_id the entire ID is
4992 not hashed anymore, instead only the hash of the Client ID is
4993 hashed. This way we can access the Client ID from the cache
4994 with Client ID but with the hash of the ID (which is a hash of
4995 the nickname) as well without any difference in performance.
4997 Added also silc_idcache_find_by_id_one_ext to do one on one
4998 searching when we have the actual ID. Added also function
4999 silc_hash_client_id_compare. The affected files are
5000 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
5002 * When hashing the name associated with a ID it is always done
5003 in lowercase. This way we can access the cache without worrying
5004 about case-sensitivity, even though, for example nicknames are
5007 * Fixed a bug in server with channel message sending. It put
5008 wrong ID type as destination ID. The affected file
5009 silcd/packet_send.c.
5011 * silc_idcache_del_by_context now deletes from all hash tables
5012 by context. Affected file lib/silccore/idcache.c.
5014 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5016 * Changed the client library to use the new ID Cache interface.
5017 Changes around the source tree.
5019 * Added silc_hash_table_rehash_ext to rehash with specific
5020 hash function. Affected file lib/silcutil/silchashtable.[ch].
5022 * Added silc_hash_string_compare to compare two strings in the
5023 hash table. Affected file lib/silcutil/silcutil.[ch].
5025 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5027 * Added new function silc_idcache_del_by_context into the
5028 lib/silccore/idcache.[ch].
5030 * Changed the server's ID list routines to use the new ID Cache
5031 interface. Changes around the source tree.
5033 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5035 * Added silc_hash_table_del[_by_context]_ext functions in to the
5036 lib/silcutil/silchashtable.[ch].
5038 Removed silc_hash_table_find_all* routines and added new
5039 silc_hash_table_find_foreach to replace them.
5041 Added silc_hash_table_replace_ext function as extended
5042 replacing function. Separated the simple hash table interface
5043 from the extended hash table interface in the file
5044 lib/silcutil/silchashtable.h.
5046 * Fixed minor bugs and changed it to use some of the new
5047 hash table functions in lib/silccore/idcache.c
5049 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5051 * Added new function silc_hash_table_find_all to return all keys
5052 in the hash table by the specified key. As the hash table is
5053 collision resistant it also makes it possible to have several
5054 duplicate keys in the hash table. This function may be used to
5055 find all of the keys from the hash.
5057 Added user_context arguments to the SilcHashFunction,
5058 SilcHashCompare and SilcHashDestructor to deliver user specified
5061 Added new fuctions silc_hash_table_find[_all]_ext to do
5062 extended lookup with specified hash and compare functions and
5063 specified user contexts.
5065 Added new function silc_hash_table_add_ext to add the key
5066 with specified hash function and user context.
5068 Added new function silc_hash_table_foreach to traverse all
5069 entrys in the hash table. Added SilcHashForeach callback
5072 Added new function silc_hash_table_del_by_context to delete
5073 the entry only if the context associated with the key matches.
5075 Affected files are lib/silcutil/silchashtable.[ch].
5077 * Removed silc_hash_[server/client/channel]_id and added just
5078 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
5079 silc_hash_id_compare to compare two ID's using as the hash table
5080 comparison function. Added also silc_hash_data to hash
5081 binary data and silc_hash_data_compare to compare it.
5083 * Removed silc_idlist_find_client_by_hash as it is not needed
5084 anymore. Affected file silcd/idlist.[ch].
5086 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
5087 to use internally the SilcHashTable. The new ID Cache is a lot
5088 faster than the old one. Some of the ID Cache interface was also
5089 rewritten and obsolete and stupid functions were removed.
5091 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5093 * Added entry_count field to the SilcHashTable to keep the number
5094 of the entries in the table. Implemented the function
5095 silc_hash_table_rehash. Added new function
5096 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
5098 Fixed a minor bug in silc_hash_table_free.
5100 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
5101 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
5102 into the lib/silcutil/silcutil.[ch].
5104 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5106 * Implemented a collision resistant hash table into the
5107 lib/silcutil/silchashtable[ch]. See the header and the source
5108 for the SilcHashTable API.
5110 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5112 * Merged dotconf version 1.0.2 into lib/dotconf.
5114 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5116 * Do not compile anything in lib/silcsim/* if the SIM support
5117 is not enabled. The tree should now compile without problems
5120 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5122 * Compiled the SILC under cygwin. Compiled and tested briefly
5123 without problems. More tests needed. The SIMs didn't compile
5126 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
5128 * Fixed possible crash in silc_get_username in the
5129 lib/silcutil/silcutil.c.
5131 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5133 * Fixed a va_arg in silc/client_ops.c.
5135 * Oops, RC5 routines were named AES and caused some problems
5136 when not using SIM's. Affected file lib/silccrypt/rc5.c.
5138 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5140 * Added new SilcIDIP structure into the lib/silccore/id.h and
5141 replaced the old `ip' fields from all SILC ID's to that type.
5142 This is a step towards IPv6 support.
5144 The silc_id_get_len takes now the ID as an extra argument.
5145 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
5146 both IPv4 and IPv6 based ID's.
5148 The affected files are lib/silccore/id.[ch] and other files
5149 around the tree using these routines.
5151 * Removed the ID length arguments in server from various
5152 silc_server_send_notify_* routines -> they are not needed
5155 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5157 * Fixed memory leak in silc_encode_pem_file in the file
5158 lib/silcutil/silcutil.c.
5160 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5162 * Check minor version as well in the SKE. Affected files are
5163 silcd/protocol.c and lib/silcclient/protocol.c.
5165 * Added --identifier option to the server so that an identifier
5166 can be when creating the public key for the server. Affected
5167 file is silcd/silcd.c.
5169 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
5170 lib/silccrypt/silcpkcs.c.
5172 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5174 * Register default ciphers and stuff when using -C option with
5175 the server. Affected file sildc/silcd.c.
5177 * Put back the servers public key filename format, it is better
5178 than the new one. For now, the client keys are saved with the
5179 new filename format. The affected file silc/client_ops.c.
5181 * Implemented the Cipher API for the rest of the ciphers that
5182 did not implement it or implemented it the wrong way.
5184 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5186 * Register default ciphers and stuff when using the -S option
5187 in the client. Affected file silc/silc.c. Same also when
5188 creating new key pair with -C option.
5190 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5192 * Fixed the silc_verify_public_key client operation function to
5193 save the public keys differently. The fingerprint is now
5194 used as filename and not the hostname. This way also the
5195 client keys are saved uniquely and not with hostnames. The
5196 affected file is silc/client_ops.c.
5198 * Trimmed the silc_hash_fingerprint function to remove extra
5199 whitespaces from the end of the fingerprint. The affected
5200 file is lib/silccrypt/silchash.c.
5204 * Added silc_cipher_register_default function to register all
5205 default ciphers. It can be used when configuration files
5206 does not exist and the application does not want any specific
5207 ciphers in any specific order.
5209 The SilcDList is now used as silc_cipher_list dynamically
5210 allocated cipher list. Removed the static list all together
5211 and now all ciphers must be allocated to the dynamic list.
5212 The silc_cipher_alloc routine was changed to check only the
5215 All silc_cipher_* routines that used to return int returns
5218 The affected files lib/silccrypt/silccrypt.[ch].
5220 * The same thing was done to silc_hash_* as for silc_cipher_*
5221 routines. Affected files lib/silccrypt/silchash.[ch].
5223 * The same thing was done to silc_pkcs_* as for silc_cipher_*
5224 routines. Affected files lib/silccrypt/silcpkcs.[ch].
5225 Added also silc_pkcs_[un]register[_default] functions.
5226 Removed the data_context from the PKCS API.
5228 * Added silc_hmac_register_default function to register default
5229 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
5230 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
5231 to unregister all hmacs at once.
5233 * Register the default ciphers, hash functions, PKCSs and HMACs
5234 if client's configuration file does not exist. The affected
5237 * The client did not load the hash functions from the SIM
5238 modules at all. Added support for this. Affected file is
5239 silc/clientconfig.c.
5241 * When decoding public key with silc_pkcs_public_key_decode, check
5242 the supported algorithm only if PKCS are registered. Affected
5243 file lib/silccrypt/silcpkcs.c. The same was done with the
5244 silc_pkcs_private_key_decode.
5246 * Fixed the SILC List routines to keep the list always in order.
5247 It used to change the list's order when traversing the list but
5248 not it preserves the order. Affected file lib/trq/silclist.h.
5250 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5252 * Added the client library to use the SilcSocketConnection's
5253 reference counter (by silc_socket_dup) to prevent the bug that
5254 the socket object may be freed underneath async operation.
5256 * The name resolv library checking fixes in the configure.in.pre.
5259 * Created new version of the protocol drafts for future
5260 development. The -03 drafts are the ones that will be changed
5261 in the trunk now and the -02 will remain as they are.
5263 * Send list of CUMODE notifys to the router when announcing
5264 the channel users to the router. Affected file silcd/server.c.
5265 If the router receiving channel founder CUMODE for a channel
5266 that already has channel founder it will send CUMODE notify
5267 to the sender to remove the channel founder rights from the
5268 announced client. Affected file silcd/packet_receive.c.
5270 * The CUMODE notify may now use Server ID as well as the entity
5271 who changes the mode. Updated protocool specs.
5273 * Updated INSTALL and README files.
5275 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5277 * New web pages in the http://silc.pspt.fi. The pages was
5282 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5284 * Implemented the [DenyConnectin] config section in the server.
5285 Added silc_server_config_denied_conn to check whether incoming
5286 connection is denied. Affected file silcd/serverconfig.[ch].
5288 * Do not check the ports when checking the incoming configuration
5289 data if the port is 0, meaning any. Affected file is
5290 silcd/serverconfig.c.
5292 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5294 * Fixed buffer overflow in silc_string_compare in the file
5295 lib/silcutil/silcutil.c.
5297 * Fixed double free in silc_server_command_leave in the file
5300 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5302 * Fixed the version checking in the server. Affected file is
5305 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5307 * Fixed the configuration data fetching when accepting new
5308 connections in the server. Affected file silcd/server.c.
5310 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5312 * Added `sender_entry' argument to the function
5313 silc_server_packet_relay_to_channel so that we can check
5314 whether some destination actually belongs to the same route
5315 the sender belongs (ie, we must not resend the packet to the
5316 sender). Affected file silcd/packet_send.[ch].
5318 * Added `servername' field to the SilcClientEntry in the server
5319 to hold the name of the server where client is from. Affected
5320 file is silcd/idlist.h.
5322 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5324 * Moved the channel message encrypting in the router betwen
5325 router connections from silc_server_channel_message to the
5326 silc_server_packet_relay_to_channel since we want to check
5327 whether we have anybody channel before encrypting anything.
5328 Affected files silcd/packet_[receive/send].c.
5330 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5332 * Fixed the [AdminConnection] server config section to support
5333 multiple entries. Affected file silcd/serverconfig.c.
5335 * Added support into the server to check the validity of the
5336 incoming connection before executing any KE or authentication
5339 * The connection configuration is now saved to the KE and
5340 connection auth protocol contexts and not fetched anymore in
5341 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
5343 * The local hosts listenning address and port is also resolved
5344 now when starting the server. We want to have the socket object
5345 to include the real address and port for the listener. Added
5346 new function silc_net_check_local_by_sock into the files
5347 lib/silcutil/silcnet.[ch].
5349 * Fixed a broadcast bug in server -> do not broadcast if we
5352 * Fixed a routing bug. Do not route broadcast packets ever.
5353 Broadcast packets must be processed always and not routed since
5354 they may be destined to some other host than yourself and thus
5355 would get routed without no good reason. Affected file is
5358 * Added function silc_server_config_is_primary_route to check
5359 whether primary router connection has been configured (a router
5360 configuration that we are initiating). If there is not, we
5361 will assume that there is only two routers in the SILC network
5362 and we will use the incoming router connection as our primary
5363 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
5365 * Changed the order of the broadcasting. Broadcast _after_ the
5366 packet has been processed not before. Affected file is
5369 * Fixed a [ClientConnection] parsing bug. The port was never
5370 parsed correctly thus resulting to port 0. Affected file
5371 silcd/serverconfig.c.
5373 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
5374 argument and did not set the broadcast packet flag. Affected
5375 file silcd/packet_send.c. Fixed same bug in the function
5376 silc_server_send_notify as well.
5378 * If we receive NEW_ID packet for our own ID in the server, ignore
5381 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5385 * Removed the nickname from the Private Message Payload.
5386 Updated the code and the protocol specs.
5388 * Updated protocol specs for submitting to the IETF.
5390 * Tweaked the Random Number Generator a bit. Affected file
5391 lib/silccrypt/silcrng.c. Exported a new function
5392 silc_rng_[global]_add_noise which can be used to add more
5395 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5397 * Do not parse packets with different timeout when protocol
5398 is active -> may cause problem with rekey. Affected file
5401 * When server receives signoff notify it must not create
5402 new channel key if the client is on any channels since the
5403 sender of the signoff notify will create it.
5405 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5407 * Added printing of error messages during SKE protocol from the
5408 failure packet sent by server during SKE. Affected file
5411 * Removed the client's failure_callback handling with timeout
5412 and handle it immediately when received.
5414 * The SKE library returned wrong type in SUCCESS and FAILURE
5415 packets. They must be 32 bit MSB not 16 bit MSB.
5417 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5419 * Ok, rewrote the logic of the re-key and now it seems to work.
5420 I tested it on high traffic with frequent re-keys without
5421 problems. Added hmac_receive (and renamed hmac to hmac_send)
5422 in SilcClientConnection in lib/silcclient/client.h and
5423 in SilcIDListData in silcd/idlist.h. Also, removed the
5424 SilcPacketParserContext's cipher and hmac fields as they are
5425 not needed anymore and actually caused some problems when
5426 the ciphers and hmac's changed underneath the packet parser.
5428 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5430 * If re-key protocol is active then process the incoming packets
5431 synchronously since we must assure that icoming packets encrypted
5432 with the old key is processed before the new keys is set to
5433 use. This is true other packets than for REKEY packets.
5434 Affected file silcd/server.c. The same was done to client library
5435 as well, affected file lib/silcclient/client.c.
5437 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5439 * Fixed bug in client and server to accept the force send if
5440 the packet is send from silc_[server/client]_packet_process
5441 function. Otherwise the packets are never delivered, oops.
5443 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5445 * Disable force sending of packets when REKEY protocol is active.
5446 We must assure that no packet is sent directly when rekey is
5447 performed. All packets must be sent through packet queue.
5448 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
5449 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
5450 function is silc_[server/client]_packet_send_real to check
5453 * Replaced the SIM paths from example config files to
5454 /usr/local/modules. Also, make install creates now
5455 /usr/local/silc/logs directory to hold all the SILC server
5458 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5460 * Made the configure.in.pre work on Solaris. Patch by salo.
5462 * Made all ciphers compatible with non-x86 machines. Defined
5463 CBC mode macros into lib/silccrypt/ciphers_def.h.
5465 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5467 * Fixed the make install.
5469 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5471 * When MAC computation fails the silc_packet_decrypt returned 0
5472 even though it was supposed to return -1. Fixed this. The
5473 affected file is lib/silccore/silcpacket.c.
5475 * Do not replace the config files in /etc/silc (in make install)
5476 if they already exist. Affected file ./Makefile.am.
5478 * Do not send re-key packets immediately but through packet queue.
5479 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
5481 * Changed silc_net_check_host_by_sock to return FALSE if the
5482 IP/DNS could not be resolved. Though, it returns the IP address
5483 now even if it could not resolve it (but returns also FALSE).
5484 Affected file lib/silcutil/silcnet.[ch].
5486 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5488 * Added silc_pkcs_decode_identifier to decode the public key's
5489 identifier. Affected file lib/silccrypt/silpkcs.[ch].
5490 Added also silc_pkcs_free_identifier. Added also new context
5491 SilcPublicKeyIdentifier.
5493 * Added -S option to the silc client. It is used to dump the
5494 contents of the specified public key file.
5496 * Changed the PKCS api to return the public key length when
5497 setting the public key.
5499 * Fixed a fatal bug in the public and private key file loading.
5500 Affected file lib/silccrypt/silcpkcs.c.
5502 * Execute the packet parsing for client with zero (0) timeout
5503 if the protocol is active. Affected file silcd/server.c.
5505 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5507 * Made the key generation options to the silcd program. Added
5508 -C option, equivalent to client's option.
5510 * Added new [ServerKeys] config section to the server. It
5511 configures the server's public and private key.
5513 * Defined generic Public Key Payload into the protocol
5514 specification to send specific type of public keys and
5517 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
5518 public key or certificate.
5520 * Implemented the GETKEY command to the server and to the
5521 client library and on user interface.
5523 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5525 * Made preliminary `make install' work.
5527 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5529 * Added SilcServerRekey context into silcd/idlist.h.
5531 * Added the PFS support as defined in the specification to the
5532 SKE protocol. Affected files lib/silcske/*.c.
5534 * Added `ske_group' field to the SilcServerRekey context to hold
5535 the number of the SKE group that is used with PFS in re-key.
5536 Affected file silcd/idlist.h.
5538 * Added PFS re-key support to the server. Affected file is
5541 * Added silc_protocol_cancel to cancel execution of the next
5542 state of the protocol. Affected file is
5543 lib/silccore/silcprotocol.[ch].
5545 * Added the re-key support with and without PFS to the client
5546 library. Re-key is performed once in an hour, by default.
5548 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
5549 Added silc_client_rekey_callback and silc_client_rekey_final.
5550 Affected files are lib/silcclient/protocol.[ch] and
5551 lib/silcclient/client.[ch].
5553 * Removed the `hmac_key' and `hmac_key_len' fields from the
5554 SilcClientConnection structure; not needed. Affected file is
5555 lib/silcclient/client.h.
5559 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5561 * Do not ask whether user wants to use the negotiated private key
5562 for private messages, just use it. Affected file is
5563 silc/local_command.c.
5565 * Added `send_enc_key' and `enc_key_len' fields to the
5566 SilcIDListData structure since they are needed in the re-key
5567 phase. Affected file is silcd/idlist.[ch].
5569 * Implemented the simple re-key protocol into the server.
5570 Affected files silcd/server.c and silcd/protocol.[ch]. The
5571 re-key will be performed once in an hour, by default.
5573 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
5574 Added silc_server_rekey, silc_server_rekey_callback and
5575 silc_server_rekey_final.
5577 * Removed Tunneled flag from the protocol. Updated the code
5578 and the specifications.
5580 * Adde `pfs' field to the SilcIDListData to indicate whether
5581 the PFS is to be performed in the re-key. Affected file is
5584 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5586 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
5587 int64 of at least the xintXX size. If void * is less that 4
5588 bytes uint32 * will be used. Defined bool as boolean.
5590 * Changed _ALL_ unsigned long and unsigned int to uint32,
5591 unsgined short to uint16 in the source tree.
5593 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
5594 not handle clients that has entry->data.registered == FALSE.
5595 They are not in the network anymore. Affected file is
5598 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5600 * Implemented the sending of the SERVER_SIGNOFF notify in the
5601 server. Affected file is silcd/server.c.
5603 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
5604 Added also silc_notify_payload_encode_args into the
5605 lib/silccore/silcnotify.[ch].
5607 * Implemented ther SERVER_SIGNOFF notify handling in the server.
5608 Affected file silcd/packet_receive.c.
5610 * Implemented the SERVER_SIGNOFF notify handling in the client
5611 library. Affected file lib/silcclient/client_notify.c. Also,
5612 implemnted the printing of the SERVER_SIGNOFF info to the
5613 application. Affected file silc/client_ops.c.
5615 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
5616 if the deleting was successful. Affected file silcd/idlist.[ch].
5618 * Added support for public key authentication in the connection
5619 authentication protocol in the client library. Affected file
5620 lib/silcclient/protocol.c.
5622 * Changed the server's silc_idlist_get_clients_by_* interface
5623 to support already allocated array so that new entries may be
5624 added to pre-allocated array. Affected file silcd/idlist.[ch].
5625 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
5626 and command replies.
5628 * All command reply functions in the server now calls the
5629 pending command callback even if error occured. This way the
5630 error will be delivered to the client as well. Affected files
5631 silcd/command.c and silcd/command_reply.c.
5633 * Fixed INFO command to return local server's info if no server
5634 was provided. Affected file lib/silcclient/command.c.
5636 * Removed RESTART command for good. Updated the code and the
5639 * Rewrote parts of the task system. It is a bit simpler now.
5640 Removed unsued task priorities. The affected files are
5641 lib/silcutil/silctask.[ch].
5643 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5645 * Moved the USERS printing from the library to the application.
5646 Affected files lib/silcclient/command.c and silc/client_ops.c.
5648 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5652 * Added channel key re-key support. The re-key is perfomed
5653 only by the router and is done once in an hour. Added `rekey'
5654 field to the SilcChannelEntry in the server. Affected files
5655 silcd/server.c and silcd/idlist.h.
5657 * Added silc_task_unregister_by_context into the file
5658 lib/silcutil/silctask.[ch].
5660 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5662 * Added SILC_UMODE_GONE mode to indicate when the client is not
5663 present in the SILC network. Added also support to the local
5664 command AWAY that will set this mode. Added support of showing
5665 "xxx is gone" in WHOIS command. The USERS command shows the
5666 gone status as well.
5668 * Fixed setting server and router operator privileges in the
5669 server's UMODE command. Affected file silcd/command.c.
5671 * Merged the SKE KE1 and KE2 payloads into one payload. The
5672 new KE payload is equivalent to the old KE2 payload.
5674 Cleaned up the SKE Start Payload parsing. It now uses the
5675 simple buffer unformatting to do the parsing. A lot faster
5678 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
5679 to the SKE that is used to indicate whether both of the SKE
5680 parties should perform authentication. By default only the
5681 responder performs authentication. By setting this flag also
5682 the initiator must do authentication. By default it is unset
5683 since in normal SKE case, client to server connection, only
5684 the responder should do authentication. When doing SKE between
5685 two clients both should perform authentication. Updated the
5686 code and the protocol specs.
5688 * A little fix to IDENTIFY command in the server. Search the
5689 client first by hash not nickname. Affected file is
5692 * Fixed the silc_client_close_connection to support closing
5693 the client to client connections wihtout deleting too much
5694 data. Affected file lib/silcclient/client.c.
5696 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
5697 are received if protocol used to be active but is not anymore
5698 the application would crash due to NULL pointer dereference.
5699 Affected files silcd/server.c and lib/silcclient/client.c.
5701 * Added `hash' field to the SilcClientConnection to include
5702 the hash function negotiated in the SKE protocol.
5704 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
5705 to set the channel founder authentication data. A client can
5706 claim the founder rights later by providing the authentication
5707 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
5708 This way the channel founder can regain the channel founder
5709 privileges even it is left the channel. This works only on
5710 local server and the client must be connected to the same
5711 server to be able to regain the founder rights. Updated the
5712 protocol specs accordingly.
5714 Added support to the CMODE command in the client to set the
5715 founder auth data. Read the README to see how to set it.
5717 Added support to the CUMODE command to claim the founder
5718 rights. Read the README to see how to do it.
5720 Added support for the founder authentication to the Channel
5721 Entry in the server. Affected file silcd/idlist.h.
5723 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
5724 server's CMODE command. Affected file silcd/command.c.
5726 * Added the following new functions into lib/silccore/silcauth.[ch]:
5727 silc_auth_get_method and silc_auth_get_data.
5729 * The server now saves the remote hosts public key to the
5730 SilcIDListData pointer. Affected file silcd/protocol.c.
5732 * The normal server now does not remove the channel entry from
5733 the cache if the founder authentication data is set. It used
5734 to remove it if the founder was the last one on the channel on
5735 the server and left the channel. The auth data is saved and
5736 if the channel is re-joined later the old entry is used with
5737 the old auth data. Affected files silcd/command_reply.c and
5740 * Removed the `pkcs' field from the SilcIDListData structure
5741 in the server; it is not used. Affected file silcd/idlist.h.
5743 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5745 * Fixed packet processing on slow links. Partial packets were
5746 never re-processed because the incoming data buffer was cleared
5747 by the application. Application must not directly clear the
5748 sock->inbuf, the packet processing routines handle it. Fixed
5749 this in client library and in server.
5751 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5753 * Fixed the WHOIS and IDENTIFY send reply function to really
5754 check whether to send list or just one entry. Affected file
5757 * Cleaned up the LEAVE command's channel key distribution. The
5758 affected file silcd/command.c.
5760 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
5761 can enforce the channel mode as well. In that case the ID
5762 includes the ID of the server. The code now enforces the
5763 mode change if the router have different mode than the server.
5765 * The notify client operation with CMODE_CHANGE notify can now
5766 return NULL client_entry pointer if the CMODE was not changed
5767 by client. Application must check for this.
5769 * Added <Server ID> argument to INFO command to support server
5770 info fetching by Server ID.
5772 * Added silc_server_announce_get_channel_users to get assembled
5773 packets of channel users of the specified channel. Affected
5774 file silcd/server.[ch].
5776 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
5777 was freed underneath the ID Cache.
5779 * Re-announce clients when the server received CHANNEL_CHANGE
5780 notify from the router. Affected file silcd/packet_send.c.
5782 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5784 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
5785 crashed since it did not handle the fact that there is no cipher
5786 called "3" and didn't check the error condition. Now fixed.
5788 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
5789 flag. It can be used to send message requests.
5791 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5793 * Implemented the RESTART command in the client.
5795 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
5796 notice type messages. Added notice printing to the user
5799 * The channel keys are not re-generated if the channel's mode
5800 is PRIVKEY, ie private key on the channel exists. Affected
5801 files silcd/server.c and silcd/command.c.
5803 * Fixed a little bug in channel message delivery when channel
5804 private keys are set in the server. Affected file is
5805 silcd/packet_send.c.
5807 * Changed the setting on channel->on_channel = TRUE from the
5808 silc_client_save_channel_key to the JOIN command reply. The
5809 key payload is not received if the private channel key is set.
5810 Affected file lib/silcclient/command_reply.c and the
5811 lib/silcclient/client_channel.c.
5813 * When the CMODE_CHANGE notify is sent and the channel private
5814 key mode is removed the channel key must be re-generated in
5815 other cells as well. Added this support for the router in the
5816 silcd/packet_receive.c.
5818 * Added new local command NOTICE to send notice message on
5819 channel. Affected file silc/local_command.[ch].
5821 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5823 * Added new local command ME to the client. It is used to send
5824 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
5825 some action. Affected file silc/local_command.[ch].
5827 * Changed channel_message and private_message client operations
5828 to deliver the message flags to the application. Added also
5829 the `flags' arguments to the silc_client_send_channel_message
5830 and silc_client_send_private_message functions. Affected file
5833 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5835 * Redefined the Private Message Payload to support private message
5836 keys and to support the new private message flags. Updated
5837 the protocol specs. Flags makes it possible to have for example
5838 CTCP style messages.
5840 * Added new type SilcPrivateMessagePayload and defined an API
5841 for it in the lib/silcclient/silcprivate.[ch].
5843 * Tested private message private keys successfully. Tested the
5844 private message key set, unset and list commands with the new
5847 * Redefined the Channel Message Payload to include the channel
5848 message flags (equal with private message flags) to support
5849 for example CTCP style messages.
5851 * Defined some of the message (for channel and private message)
5852 flags. Updated the protocol specs and added the flags to the
5853 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5855 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5857 * Added SilcKeyAgreementStatus type to the key agreement routines
5858 to indicate the current status and error if one occured.
5859 The status types are defined in the lib/silcclient/silcapi.h.
5861 * Added new local command KEY that is used to set and unset private
5862 keys for channels, set and unset private keys for private messages
5863 with remote clients and to send key agreement requests and
5864 negotiate the key agreement protocol with remote client. The
5865 key agreement is supported only to negotiate private message keys,
5866 it currently cannot be used to negotiate private keys for channels,
5867 as it is not convenient for that purpose.
5869 * Fixed a minor pending callback setting bug in the function
5870 silc_client_get_client_by_id_resolve, now the function works.
5871 Affected file lib/silcclient/idlist.c.
5873 * Added function silc_net_get_local_port to get local bound
5874 port by socket. Added to lib/silcutil/silcnet.[ch].
5876 * Added `sockets' and `sockets_count' fields to the SilcClient
5877 object. They hold the sockets of the listenning sockets in
5878 the client. Listenning sockets may be for example the key
5879 agreement server. Affected file lib/silcclient/client.[ch].
5880 Added functions the silc_client_add_socket and the
5881 silc_client_del_socket. They are exported to the application
5884 * Added ~./silc/clientkeys to support other client's public keys.
5886 * Renamed verify_server_key client operation to verify_public_key
5887 and added one argument to indicate the type of the connection
5888 (server, client etc.).
5890 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5892 * Added silc_server_connection_auth_request to handle the
5893 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5894 silcd/packet_receive.[ch].
5896 * Added silc_server_send_connection_auth_request into the
5897 silcd/packet_send.c to send the connection auth request packet.
5899 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5902 * Fixed the public key authentication in responder side in the
5903 server. The `auth_data' pointer includes the SilcPublicKey
5904 not the path to the public key. Affected file silcd/protocol.c.
5906 * Implemented the public key authentication in the initiator side
5907 in the server. Affected file silcd/protocol.c.
5909 * Removed the [RedirectClient] config section from the server
5910 configuration. Is not needed and I don't want to implement it.
5912 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5914 * Cleaned up the CMODE command in the server. It now works
5915 correctly and supports all the modes defined in the protocol.
5916 Affected file is silcd/command.c.
5918 * Added `hmac_name' field to the SilcChannelEntry in the server
5919 to hold the default HMAC of the channel. It can be set when
5920 creating the channel (with JOIN command). Affected files
5923 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5924 type to indicate the change of the current cipher and hmac
5925 on the channel. Client can safely ignore the <cipher> argument
5926 (if it chooses to do so) since the CHANNEL_KEY packet will
5927 force the channel key change anyway. The <hmac> argument is
5928 important since the client is responsible of setting the new
5929 HMAC and the hmac key into use.
5931 * Fixed the CMODE command in the client library as well.
5933 * Tested CMODE command in router environment successfully.
5935 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5937 * Show the version of the remote client (or server) when connecting
5938 to the server. It is logged to the log file. Affected file
5939 is silcd/protocol.c.
5941 * Fixed the KILLED notify handling in the client library. The
5942 client must be removed from all channels when receiving the
5945 Also, do not remove the client entry when giving the KILL
5946 command but when the KILLED notify is received.
5948 * Removed silc_idlist_find_client_by_nickname from the server.
5949 Not needed anymore. Affected files silcd/idlist.[ch].
5951 * Implemented the CHANNEL_CHANGE notify type handling to the
5952 server. Affected file silcd/server.c.
5956 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5958 * Added silc_server_send_notify_invite to send the INVITE
5959 notify between routers.
5961 * Implemented the INVITE command correctly to the server.
5963 * Implemented the INVITE notify type handling in the server.
5965 * Implemented the INVITE command to the client library and on the
5968 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5970 * Added function silc_server_get_client_resolve to find the
5971 client entry by ID from all ID lists and then resolve it
5972 (using WHOIS) if it cannot be found. Affected file is
5975 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5977 * Implemented the BAN command to the client library.
5979 * The JOIN command in the server now checks the invite list
5982 * Changed the silc_command_reply_payload_encode_va and the
5983 silc_command_payload_encode_va to support that if argument is
5984 NULL it ignores and checks the next argument. Affected file
5985 lib/silccore/silccommand.c.
5987 * Added silc_server_send_notify_ban to send the BAN notify
5988 type between routers.
5990 * Chaned the silc_notify_payload_encode to support that if
5991 argument is NULL it ignores and checks the next argument.
5992 Affected file lib/silccore/silcnotify.c.
5994 * Tested ban lists in router environment successfully.
5996 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5998 * Implemented BAN command to the server, in silcd/command.[ch].
6000 * Removed the BAN and INVITE_LIST modes from the CMODE command
6003 * Added function silc_string_match to regex match two strings.
6004 Affected files lib/silcutil/silcutil.[ch].
6006 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6008 * Redefined parts of the SilcChannelEntry in the server to support
6009 the new ban and invite lists.
6011 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6013 * Redefined the INVITE command. The same command can be used to
6014 invite individuals to the channel but also to manage the invite
6015 list of the channel (to add to and remove from the invite list).
6016 Updated the protocol specs.
6018 * Added new command SILC_COMMAND_BAN that can be used to manage
6019 the ban list of the channel. Updated the protocol specs.
6021 * Removed the channel modes: the SILC_CMODE_BAN and the
6022 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
6023 in the CMODE command. The equivalent features are now available
6024 using INVITE and BAN commands. Updated the protocol specs.
6026 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
6027 in the network about change in the current ban list. The notify
6028 type is not used by the client.
6030 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
6031 support the invite lists.
6033 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6035 * Added new function silc_string_regexify that converts string
6036 including wildcard characters into regex string that can
6037 be used by the GNU regex library. Added into the file
6038 lib/silcutil/silcutil.[ch].
6040 Added silc_string_regex_combine to combine to regex strings
6041 into one so that they can be used as one regex string by
6042 the GNU regex library. Added into the file
6043 lib/silcutil/silcutil.[ch].
6045 Added silc_string_regex_match to match two strings. It returns
6046 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
6048 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6050 * Imported GNU regex to the soruce tree into lib/contrib.
6051 Fixed some compiler warning from the regex.c.
6053 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6055 * Fixed MOTD command in the server to work in router environment.
6057 * Fixed the MOTD command in the client library to support
6058 the server argument in the command.
6060 * Added `nickname_len' argument to the silc_idlist_add_client
6061 in the server, as the `nickname' argument may be binary data
6064 * Added silc_idlist_get_channels to return all channels from
6067 * Implemented LIST command to the server. Affected file is
6070 * Implemented the LIST command to the client library and on the
6073 * Added [<user count>] argument to the LIST command reply.
6074 With private channels the user count is not shown.
6076 * Updated TODO and README.
6078 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6080 * The client entry's data.registered must be TRUE even with
6081 global client entry on global client list. The data.registered
6082 is used to check whether the client is anymore in the network,
6083 for example with WHOWAS command so it must be valid.
6085 * Fixed the WHOWAS command in the server. It now actually works
6086 in router environment. Added function into silcd/command_reply.c
6087 silc_server_command_reply_whowas_save.
6089 * Added silc_idlist_purge function to the silcd/idlist.c
6090 to periodically purge the ID Cache.
6092 * Fixed INFO command in the server. It works now in router
6093 environment. Added <server name> argument to the INFO command
6094 reply. Updated the protocol specs.
6096 * Fixed minor bug in silc_idcache_purge to not purge if the
6097 expire value is zero.
6099 * Fixed various bugs in WHOIS and IDENTIFY command handling as
6100 they were buggy because of the WHOWAS information.
6102 * Fixed local command MSG to handle the async resolving of
6103 the remote client properly. It used to fail the first MSG.
6104 Affected file silc/local_command.c.
6106 * Added `data_len' field to SilcIDCache context.
6108 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6110 * Update TODO. Todo in commands in the server.
6112 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6114 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
6115 used by routers as broadcast packet to inform other routers
6116 about the changed user mode.
6118 Implemented the notify handling in the server. Affected file is
6119 silcd/packet_receive.c. Added the function
6120 silc_server_send_notify_umode to the silcd/packet_send.[ch].
6122 * Added new generic Channel Payload and deprecated the New Channel
6123 Payload. The New Channel Payload is now the generic Channel
6126 * Added new argument `mode' to the silc_server_send_new_channel
6127 as it is required in the Channel Payload now.
6129 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
6130 and created a new and real SilChannelPayload to represent the
6131 new generic Channel Payload. Implemented the encode/decode
6132 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
6134 * Added silc_server_get_client_channel_list to return the list
6135 of channels the client has joined for WHOIS command reply.
6136 Affected file silcd/server.[ch].
6138 * Implemented the channel list sending in the WHOIS command reply
6139 in server and in the client.
6141 Implemented the channel list displaying on the user interface
6142 as well. Affected file silc/client_ops.c.
6144 * Added silc_channel_payload_parse_list to parse list of Channel
6145 Payloads. It returns SilcDList list of SilcChannelPayloads.
6146 Client for example can use this function to parse the list of
6147 channels it receives in the WHOIS command reply. The caller
6148 must free the list by calling silc_channel_payload_list_free.
6149 Affected files lib/silccore/silcchannel.[ch].
6151 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6153 * Added one new argument <user mode> to the WHOIS command reply
6154 to return the mode of the user in SILC. Updated the protocol
6157 Implemented it to the server and client.
6159 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6161 * Fixed the mode printing on the user interface on joining.
6162 Affected file silc/client_ops.c.
6164 * Implemented the UMODE command and user modes in general to the
6165 client library and to the user interface.
6167 * Implemented the UMODE command to the server.
6169 * The server now sends UNKNOWN_COMMAND error status if client sends
6170 unknown command. Affected file silcd/command.c.
6172 * All server commands now handle the command identifier the right
6173 way when sending the command reply to the client. The client can
6174 use to identify the command replies with the identifier.
6176 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6178 * Added silc_server_get_client_route to resolve the route to
6179 the client indicated by the client ID. Affected file is
6182 * Added silc_server_relay_packet as general function to relay
6183 packet to arbitrary destination. This deprecates functions
6184 like _send_private_message_key, _relay_notify etc. Affected
6185 file is silcd/packet_send.[ch].
6187 Removed silc_server_send_key_agreement,
6188 silc_server_send_private_message_key and
6189 silc_server_packet_relay_notify functions from the file
6190 silcd/packet_send.[ch].
6194 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
6195 server. Affected file silcd/packet_receive.[ch].
6197 * Implemented the KILL command to the client. Implemented the
6198 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
6199 Affected files lib/silcclient/command[_reply].c and
6200 lib/silcclient/client_notify.c. Implemented the KILL notify
6201 printing in the user inteface.
6203 * Fixed a lot silc_parse_nick memory leaks from the client
6204 library in the file lib/silcclient/command.c.
6206 * Changed the silc_server_send_notify_on_channels's `sender'
6207 argument from SilcSocketConnection to SilcClientEntry to
6208 check the sender as entry and not as connection object and not
6209 to send to the client provided as argument. The affected file
6210 is silcd/packet_send.[ch].
6212 * The notify packets that are destined directly to the client used
6213 to not to be processed by the server. Now changed that and the
6214 server processes all notify packets. After relaying the packet
6215 to the client the notify packet is processed in the server.
6217 * The silc_server_free_client_data now checks whether there is
6218 pending outgoing traffic for the client and purges the data to
6219 the network before removing the client entry.
6221 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6223 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
6224 an client is killed from the SILC Network. Updated the protocol
6227 Added new function silc_server_send_notify_killed to the
6228 silcd/packet_send.[ch].
6230 * Added function silc_server_packet_relay_notify to relay notify
6231 packets that are destined directly to a client. In this case
6232 the server does not process the notify packets but merely relays
6233 it to the client. Affected file silcd/packet_send.[ch].
6235 Added also silc_server_packet_process_relay_notify to check
6236 whereto relay the notify. Affected file is
6237 silcd/packet_receive.[ch].
6239 * Implemented the KILL command to the server.
6243 * Added the backup schema desgined last fall to the protocol
6244 specs for everyone to see. The specification is in the
6245 *-spec-xx.txt draft and the packet type definitions for the
6246 backup routers is in *-pp-xx.txt draft. Thusly, added also
6247 new packet type SILC_PACKET_CELL_ROUTERS.
6249 * A big security problem in the implementation discovered. The
6250 signoff of an client did not cause new channel key generation
6251 which it of course should've done. The channel keys must be
6252 always re-generated when client leaves (or signoffs) the channel.
6253 The silc_server_remove_from_channels funtion now handles
6254 the channel key re-generation.
6256 * Added `sender' argument to the silc_server_send_notify_on_channels
6257 to not to send the client provided as argument. Affected file
6258 silcd/packet_send.[ch].
6260 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6262 * Implemented OPER and SILCOPER commands into the server and
6265 * Added silc_auth_verify and silc_auth_verify_data to verify
6266 the authentication directly from the authentication payload.
6267 It supports verifying both passphrase and public key based
6268 authentication. Affected file lib/silccore/silcauth.[ch].
6270 * Added `hash' field to the SilcIDListData structure. It is the
6271 hash negotiated in the SKE protocol. Affected file is
6274 * Slight redesigning of the SilcAuthPayload handling routines.
6275 Do not send SilcPKCS but SilcPublicKey as argument.
6277 * Implemented the public key authentication support to the
6278 serverconfig. The public key is loaded from the provided path
6279 and saved as authentication data to void * pointer. Thus,
6280 changed the unsigned char *auth_data to void *auth_data;
6282 * Fixed SHUTDOWN command to send the reply before the server
6283 is shutdown. :) Affected file silcd/command.c.
6285 * Fixed fatal bug in CONNECT command. The hostname was invalid
6286 memory and server crashed. Affected file silcd/command.c.
6288 * Fixed fatal bug in CLOSE command. The server_entry became
6289 invalid but was referenced later in the command. Affected file
6292 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6294 * Fixed fatal bug in failure packet handling. Server ignored
6295 the failure and thus crashed when it came.
6299 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6301 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
6302 that the command may be executed only once in (about) 2 seconds.
6303 The old SILC_CF_LAG flag is same but allows command bursts up
6304 to five before limiting.
6306 Added the support for CF_LAG and CF_LAG_STRICT flags to the
6307 server code. Various commands now includes the CF_LAG_STRICT
6308 flag to disallow any kind of miss-use of the command.
6310 * Fixed the silc_buffer_unformat to not to allocate any data
6311 if the length of the data is zero. It used to allocate the
6312 length + 1. Affected file lib/silcutil/silcbuffmt.c.
6314 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6316 * Changed the format of AdminConnection configuration section
6317 in the server. Added username of the admin to the format.
6318 Affected files silcd/serverconfig.[ch].
6320 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
6321 to return admin configuration data by host, username and/or
6324 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6326 * Implemented WHOWAS command to the server. Added the functions:
6328 silc_server_command_whowas_parse,
6329 silc_server_command_whowas_send_reply,
6330 silc_server_command_whowas_from_client and
6331 silc_server_command_whowas_from_server
6333 * Added <Client ID> argument to the WHOWAS command reply. Updated
6334 the protocol specs accordingly.
6336 * Implemented WHOWAS command and command_reply to the client
6339 Implemented the WHOWAS printing on the user interface.
6341 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6343 * Added new argument to the WHOWAS command reply, the real name.
6344 It is an optional argument. Updated the protocol specs.
6346 * Added SilcIDCacheDestructor callback that is registered when
6347 the SilcIDCache is allocated. The callback is called when
6348 an cache entry in the ID Cache expires, or is purged from the
6349 cache. Added into lib/silccore/idcache.[ch].
6351 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
6352 to destruct the client entries when the cache entry expires.
6353 Other ID Cache's in server and in the client library ignores
6356 * If the ID Cache entry's `expire' field is zero then the entry
6357 never expires. Added boolean `expire' argument to the
6358 silc_idcache_add function in the lib/silccore/idcache.[ch].
6359 If it is TRUE the default expiry value is used.
6361 * Added silc_server_free_client_data_timeout that is registered
6362 when client disconnects. By default for 5 minutes we preserve
6363 the client entry for history - for WHOWAS command.
6365 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6367 * Added support to the server to enforce that commands are not
6368 executed more than once in 2 seconds. If server receives
6369 commands from client more frequently, timeout is registered
6370 to process the commands. Affected file silcd/command.c.
6371 Added new function silc_server_command_process_timeout.
6373 * Changed NICK_NOTIFY handling in client library to check that
6374 if the client's nickname was changed, so there is no need to
6375 resolve anything from the server.
6377 * Removed error printing from the WHOIS and IDENTIFY commands.
6378 If error occurs then it is ignored silently in the client library.
6379 The application, however, may map the received error to
6380 human readable error string. The application currently maps
6381 the NO_SUCH_NICKNAME error to string.
6383 * Made the command status message public to the application. Moved
6384 them from lib/silcclient/command_reply.c to
6385 lib/silcclient/command_reply.h. The application can map the
6386 received command status to the string with the
6387 silc_client_command_status_message function.
6389 * Added check to the server to check that client's ID is same
6390 as the Source ID in the packet the client sent. They must
6393 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6395 * Added dist-bzip hook to the Makefile.am to make bzip2
6396 compressed distributions.
6398 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6400 * Server now enforces the maximum length for the nickname and
6401 the channel as protocol specification dictates. 128 bytes for
6402 nickname and 256 bytes for channel name.
6404 * Moved the WHOIS printing to the application. The client libary
6405 does not print out the WHOIS information anymore, the application
6406 must do it. Renamed silc_client_command_reply_whois_print to
6407 the silc_client_command_reply_whois_save.
6409 The client's idle time is also sent to the application now, and
6410 the idle is shown on screen.
6412 * Added silc_client_command_reply_identify_save to save the
6413 received IDENTIFY entries.
6415 * Do not check for channel private keys in message sending and
6416 reception if the channel does not have the PRIVKEY mode set.
6417 Affected file lib/silclient/client_channel.c.
6419 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6421 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
6422 just surfaced after chaning the JOIN procedure.
6424 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6426 * Added silc_client_get_clients_by_list to get client entries
6427 from Client ID list, that is returned for example by JOIN
6428 and USERS command replies. The application should use this
6429 function for example when JOIN command reply is received to
6430 resolve the clients already on the channel (library does not
6431 do that anymore as USERS command reply is not used in the JOIN
6432 procedure anymore). Affected files lib/silcclient/silcapi.h and
6433 lib/silcclient/idlist.c.
6435 * JOIN command reply and USERS command reply returns now SilcBuffer
6436 pointers instead of unsigned char pointers when returning
6437 the client list and mode list.
6439 * Added <Client ID> argument to the JOIN command reply, mainly
6440 for the server to identify for which client the command was
6441 originally sent. Updated protocol specs accordingly.
6443 * Added SilcDlist private_key pointer to the SilcChannelEntry
6444 in the client to support the channel private keys. Affected
6445 file is lib/silcclient/idlist.h.
6447 * Added SilcChannelPrivateKey argument to the function
6448 silc_client_send_channel_message so that application can choose
6449 to use specific private ke if it wants to. If it is not provided,
6450 the normal channel key is used, unless private keys are set.
6451 In this case the first (key that was added first) is used
6452 as the encryption key.
6454 * Implemented the support for channel private key handling.
6455 Implemented the following functions:
6457 silc_client_add_channel_private_key,
6458 silc_client_del_channel_private_keys,
6459 silc_client_del_channel_private_key,
6460 silc_client_list_channel_private_keys and
6461 silc_client_free_channel_private_keys
6463 Affected file lib/silcclient/client_channel.c.
6465 * Added the support for the private keys in the channel message
6466 sending and encryption and in the message reception and
6467 decryption. Affected funtions are
6468 silc_client_send_channel_message and silc_client_channel_message.
6470 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6472 * Added SKE's key verify callback to the client library's
6473 KE protocol context. Affected files lib/silcclient/protocol.[ch].
6475 * Removed the statement that server (or router) must send USERS
6476 command reply when joining to the channel so that the client
6477 knows who are on the channel. Instead, the client list and
6478 client's mode list is now sent in the JOIN command reply to the
6479 client who joined channel. This is better solution.
6481 * Added function silc_server_get_users_on_channel and function
6482 silc_server_save_users_on_channel to the silcd/server.[ch].
6484 * Removed function silc_server_command_send_users from the
6487 * Do not show topic on the client library anymore. The topic is
6488 sent in the command reply notify to the application and the
6489 application must show the topic now.
6491 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6493 * Added client searching by nickname hash into the IDENTIFY and
6494 WHOIS commands in the server as they were clearly missing from
6495 them. Affected file is silcd/command.c.
6497 * Fixed a bug in private message receiving in the client library.
6498 The remote ID was freed and it wasn't supposed, now it is
6501 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6503 * Minor fix to the channel payload; allocate the data area, as it
6504 needs to be of specific length.
6506 * If the key agreement port is zero then the operating
6507 system will define the bound port. Affected files are
6508 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
6510 * Added new function silc_channel_payload_decrypt into the file
6511 lib/silccore/silcchannel.[ch].
6513 * Moved the channel message etc, check from silc_packet_decrypt
6514 to applications. The library calls now a generic
6515 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
6516 when the packet is either normal or special. This was done to
6517 allow more wide range of checking that was not allowed when
6518 the code was in library. Now applications can do virtually any
6519 checks to the packet and return to the library the decision how
6520 the packet should be processed. Affected files are
6521 lib/silccore/silcpacket.[ch].
6523 Added silc_server_packet_decrypt_check to the server and
6524 silc_client_packet_decrypt_check to the client library.
6526 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
6527 to send with specified source and destination information.
6529 * Channel message delivery between routers was broken after the
6530 channel key distribution was fixed earlier. The channel key
6531 was used be to distributed to other routers as well which is not
6532 allowed by the protocol. Now this is fixed and channel keys
6533 really are cell specific and the channel message delivery between
6534 routers comply with the protocol specification.
6536 * Fixed various commands in server to check also the global list
6537 for the channel entry and not just the local list. The affected
6538 file silcd/command.c.
6540 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6542 * Added assert()s to buffer formatting and unformatting routines
6543 to assert (if --enable-debug) when error occurs. Affected
6544 file: lib/silcutil/silcbuffmt.c.
6546 * Changed to auto-reconnect to check whether the remote host is
6547 router and register the re-connect timeout if it is. It used
6548 to check that whether we are normal server, but router must do
6549 auto-reconnect with another router as well. Affected file
6552 * Removed the [<key len>] option from CMODE command as the cipher
6553 name decides the key length, nowadays. See the defined ciphers
6554 from the protocol specification.
6556 * Added [<hmac>] option to the CMODE command to define the HMAC
6557 for the channel. Added SILC_CMODE_HMAC channel mode.
6559 * Added [<hmac>] option for the JOIN command so that user can
6560 select which HMAC is used to compute the MACs of the channel
6563 * Added Hmac field to the Channel Message Payload. The integrity
6564 of plaintext channel messages are now protected by computing
6565 MAC of the message and attaching the MAC to the payload. The
6566 MAC is encrypted. Now, it is clear that this causes some
6567 overhead to the size of the packet but rationale for this is that
6568 now the receiver can verify whether the channel message decrypted
6569 correctly and also when private keys are set for the channel the
6570 receiver can decrypt the packet with several keys and check from
6571 the MAC which key decrypted the message correctly.
6573 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
6574 lib/silccrypt/silccipher.[ch].
6576 * Added silc_hash_len to return the digest length into the
6577 lib/silcrypt/silchash.[ch].
6579 * Rewrote parts of Silc Channel Payload interface in the
6580 lib/silccore/silcchannel.[ch]. The encode function now also
6581 encrypts the packet and parse function decrypts it.
6583 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6585 * Fixed a minor formatting bug in the SKE's key material processing.
6586 It actually might have processed the keys wrong way resulting
6589 * Redefined the mandatory HMAC algorithms and added new algorithms.
6590 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
6591 and hmac-md5 truncated to 96 bits. The mandatory is now
6592 hmac-sha1-96. Rest are optional (including the one that used
6593 to be mandatory). Rationale for this is that the truncated HMAC
6594 length is sufficient from security point of view and can actually
6595 make the attack against the HMAC harder. Also, the truncated
6596 HMAC causes less overhead to the packets. See the RFC2104 for
6599 * Added new [hmac] configuration section. The SKE used to use
6600 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
6601 is of course wrong. The official names that must be proposed in
6602 the SKE are the ones defined in the protocol specification
6603 (hmac-sha1-96 for example). The user can configure any hmac
6604 using any hash function configured in the [hash] section. At
6605 least, the mandatory must be configured.
6607 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
6609 * Added HMAC list to the SKE proposal list. It has now both
6610 hash algorithm list and HMAC list. This makes the protocol
6611 incompatible with previous versions. The SKE now seems to work
6612 the way it is supposed to work, for the first time actually.
6614 * Defined plain Hash algorithms to the protocol specification.
6617 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6619 * Implemented support for key agreement packets into the server.
6620 Added functions silc_server_key_agreement and
6621 silc_server_send_key_agreement. Other than these functions,
6622 server has nothing to do with this packet.
6624 * Added support for private message key packets into the server.
6625 Added functions silc_server_private_message_key and
6626 silc_server_send_private_message_key.
6630 * Changed the silc_[client|server]_protocol_ke_set_keys to be
6631 called in the protocol's final callback instead in the END
6632 protocol state. This makes a little more sense and in the same
6633 time in client we can use the same protocol routines for normal
6634 key exchange and to key agreement packet handling as well.
6636 * Added to both client's and server's KE protocol context the
6637 SilcSKEKeyMaterial pointer to save the key material. We will
6638 bring the key material to the protocol's final callback by doing
6639 this. The final callback must free the key material.
6641 * Added SKE's packet_send callback into client's KE protocol
6642 context so that the caller can choose what packet sending function
6643 is used. This way we can use different packet sending when
6644 doing normal SKE when doing key agreement packet handling (in
6645 the key agreement packet handling we do not want to encrypt
6648 * Implemented the responder side of the key agreement routines
6649 in the client. The client can now bind to specified port and
6650 accept incoming key negotiation. The key material is passed
6651 to the application after the protocol is over.
6653 * Implemented the processing of incoming Key Agreement packet
6654 in the client. Added function silc_client_key_agreement to
6657 * Implemented the intiator side of the key agreement routines
6658 in the client. The client can now initiate key agreement with
6659 another remote client. The key material is passed to the
6660 application after the protocol is over.
6662 * Created client_keyagr.c to include all the key agreement
6665 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
6666 SILC_TASK_CALLBACK except that it is not static.
6668 * Created client_notify.c and moved the Notify packet handling
6669 from the client.[ch] into that file.
6671 * Created client_prvmsg.c and moved all private message and
6672 private message key routines from the client.[ch] into that file.
6674 * Create client_channel.c and moved all channel message and
6675 channel private key routines from the client.[ch] into that file.
6677 * Changed silc_client_get_client_by_id_resolve to resolve with
6678 WHOIS command instead of IDENTIFY command, in the file
6679 lib/silclient/idlist.c.
6681 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6683 * Implemented the SKE's responder side to the Client library.
6685 * When FAILURE is received to the protocol do not trust it
6686 blindly. Register a timeout to wait whether the remote closes
6687 the connection as it should do it, only after that process the
6688 actual failure. This was changed to both client and server.
6690 * Added client_internal.h to include some of the structures
6691 there instead of client.h in lib/silcclient/.
6693 * Added function silc_task_unregister_by_callback to unregister
6694 timeouts by the callback function.
6696 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6698 * Some "Incomplete WHOIS info" errors has been appearing on the
6699 log files. Took away the entry->userinfo check from WHOIS
6700 reply sending. The entry->userinfo is now " " if client did not
6701 provide one. I thought this was fixed earlier but something
6702 is wrong still. Let's see if the error still appears.
6704 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6706 * Fixed a minor bug in the login when the channel key is
6707 re-generated in the server. It used to generate the key in
6708 wrong order and thus caused problems in the channel traffic.
6710 * Fixed a minor bug in channel key distsribution after
6711 KICK command. The key was not sent to the router even though
6714 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6716 * Added silc_ske_process_key_material_data as generic routine
6717 to process any key material as the SILC protocol dictates. The
6718 function is used by the actual SKE library but can be used by
6719 applications as well. This relates to the private message keys
6720 and the channel private keys since they must be processed the
6721 same way the normal SILC session keys. The protocol dictates
6722 this. Affected files: lib/silcske/silcske.[ch].
6724 Added also silc_ske_free_key_material to free the
6725 SilcSKEKeyMaterial structure.
6727 * Defined silc_cipher_set_key function to set the key for
6728 cipher without using the object's method function. The affected
6729 files: lib/silccrypt/silccipher.[ch].
6731 * Implemented silc silc_client_add_private_message_key,
6732 silc_client_add_private_message_key_ske,
6733 silc_client_del_private_message_key,
6734 silc_client_list_private_message_keys and
6735 silc_client_free_private_message_keys functions in the
6738 Added functions silc_client_send_private_message_key to send
6739 the Private Message Key payload and silc_client_private_message_key
6740 to handle incoming Private Message Key payload.
6742 * Added Cipher field to the Private Message Key payload to set
6743 the cipher to be used. If ignored, the default cipher defined
6744 in the SILC protocol (aes-256-cbc) is used.
6746 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6748 * Removed lib/silcclient/ops.h file.
6750 Redefined parts of the SILC Client Library API. Created new
6751 file silcapi.h that deprecates the ops.h file and defines the
6752 published Client Library API. Defined also private message key
6753 API and channel private key API into the file.
6755 This is the file that the application must include from the
6756 SILC Client Library. Other files need not be included by
6757 the application anymore.
6759 * Added new key_agreement client operation callback and also
6760 defined the Key Agreement library API for the application.
6762 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6764 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
6765 is used by clients to request key negotiation between another
6766 client in the SILC network. If the negotiation is started it
6767 is performed using the SKE protocol. The result of the
6768 negotiation, the secret key material, can be used for example
6769 as private message key.
6771 Implemented the Key Agreement payload into the files
6772 lib/silccore/silauth.[ch].
6774 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6776 * Redefined ciphers for the SILC protocol. Added some new ciphers
6777 and defined the key lengths for the algorithms. Changed the
6778 code accordingly. The default key length is now 256 bits.
6780 * Fixed SKE key distribution function silc_ske_process_key_material
6781 when the key length is more than 128 bits. The default key
6782 length in SILC is now 256 bits.
6784 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
6785 to indicate unsupported algorithm.
6787 * Renamed rijndael.c to aes.c and all functions as well.
6789 * Fixed a long standing channel key setting bug in client library.
6790 Weird that it has never surfaced before.
6792 * Fixed bug in channel deletion. If the entire channel is removed
6793 then it must also delete the references of the channel entry
6794 from the client's channel list as the client's channel entry and
6795 the channel's client entry share same memory.
6797 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6799 * Implemented CONNECT and SHUTDOWN commands in the client.
6801 * Implemented CLOSE command to the client.
6803 * Added the function silc_idlist_find_server_by_name into the
6804 files silcd/idlist.[ch].
6806 Added the function silc_idlist_find_server_by_conn into the
6807 files silcd/idlist.[ch].
6809 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6811 * DIE command was renamed to SHUTDOWN. Updated the both code
6814 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
6815 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
6817 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
6820 * Added function silc_server_create_connection function to create
6821 connection to remote router. My server implementation actually
6822 does not allow router to connect to normal server (it expects
6823 that normal server always initiates the connection to the router)
6824 so the CONNECT command is only good for connecting to another
6827 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6829 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
6830 or some other client was kicked from the channel.
6832 Implemented the handling of the notify type to both client
6835 Implemented silc_server_send_notify_kicked to send the KICKED
6836 notify. It is used to send it to the server's primary router.
6838 * Implemented the KICK command into server and client.
6840 * Added `query' argument to the silc_idlist_get_client function
6841 to indicate whether to query the client from server or not if
6844 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
6845 to indicate that the client is not channel founder.
6849 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6851 * Removed the rng context from SilcPacketContext structure and
6852 changed that the packet routine uses the Global RNG API.
6854 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6856 * Added support for quit message that client can "leave" on the
6857 channel when it quits the SILC. It is ditributed inside the
6858 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6860 Added silc_server_free_client_data that will take the
6861 signoff message as argument.
6863 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6865 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6867 * Updated parts of the protocol specification to keep it up
6870 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6872 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6873 payloads in one packet.
6875 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6876 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6877 use now the new List flag.
6879 * Also deprecated the following packet types: REPLACE_ID,
6880 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6882 * Added list support for Notify packet in server.
6884 * Added silc_server_send_notify_channel_change to send the
6885 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6886 the silc_server_send_replace_id.
6888 * Added silc_server_send_notify_nick_change to send the
6889 NICK_CHANGE notify type. Deprecates the function
6890 silc_server_send_replace_id.
6892 * Added silc_server_send_notify_join to send the JOIN notify type.
6893 Deprecates the function silc_server_send_new_channel_user.
6895 * Added silc_server_send_notify_leave to send LEAVE notify type.
6896 Deprecates the function silc_server_send_remove_channel_user.
6898 * Added silc_server_send_notify_cmode and
6899 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6900 types. Deprecates the silc_server_send_set_mode function.
6902 * Added SERVER_SIGNOFF notify type to indicate that server has
6903 quit. This means that all clients on the channel from that
6904 server will drop. This can be also used when netsplit happens.
6906 Deprecated REMOVE_ID packet type since it is not needed anymore
6909 Added silc_server_send_notify_server_signoff to send the
6910 SERVER_SIGNOFF notify type. Deprecates the function
6911 silc_server_send_remove_id.
6913 Added also silc_server_send_notify_signoff to send the
6914 SIGNOFF notify type.
6916 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6917 SILC protocol from this day on. Changed the protocol
6918 specification as well.
6920 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6921 notify type. It is used between routers to notify about
6922 topic changes on a channel.
6924 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6927 * Partly updated the protocol specification to comply with the
6928 changes now made. It is still though a bit outdated.
6930 * The JOIN notify type now takes one extra argument <Channel ID>.
6931 The packet used to be destined to the channel but now the
6932 JOIN type may be sent as list thus it is impossible to
6933 destine it to any specific channel. By adding this argument
6934 it is again possible.
6936 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6938 * Added CREDITS file. The CHANGES and CREDITS file will appear
6939 in the distribution as well.
6941 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6943 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6944 types in the server's silcd/packet_receive.c.
6946 * Implemented CMODE and CUMODE to work in router environment.
6948 * Fixed minor encoding and decoding buglet from the
6949 lib/silccore/silcmode.c.
6951 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6954 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6956 * Changed all SilcConfigServer* and silc_config_server* to
6957 SilcServerConfig* and silc_server_config*, respectively.
6960 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6962 * Associated the ID (client or server ID) to the Authentication
6963 Payload to avoid any possibility of forging. Updated the
6964 protocol specification and the code accordingly.
6966 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6968 * The RSA key length is now save to the RsaKey context in the
6969 key generation process in lib/silccrypt/rsa.c. The key length
6970 is now used to figure out the maximum size of the block allowed
6971 to be encrypted/signed.
6973 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6974 is equivalent to the silc_mp_mp2bin but does not allocate any
6977 * Changed silc_mp_mp2bin API to take length argument. If it is
6978 non-zero then the buffer is allocated that large. If zero, then
6979 the size is approximated using silc_mp_sizeinbase, which however
6982 * Created Global RNG API which is global RNG that application can
6983 initialize. After initializing, any routine anywhere in the
6984 code (including library) can use RNG without allocating a new
6985 RNG object. This was done to allow this sort of use of the
6986 RNG in code that has no chance to allocate RNG object. All
6987 applications currently allocate this and many routines in the
6988 library use this. Affected file lib/silccrypt/silcrng.[ch].
6990 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6991 it to use the Global RNG API.
6993 * Defined Authentication Payload into protocol specification that
6994 is used during SILC session to authenticate entities. It is
6995 used for example by client to authenticate itself to the server
6996 to obtain server operator privileges.
6998 Implemented this payload into the lib/silccore/silcauth.[ch].
6999 Implemented also routines for public key based authentication
7000 as the new protocol specification dictates.
7002 Moved definitions of different authentication methods from
7003 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
7005 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
7006 silc_pkcs_verify and silc_pkcs_sign_with_hash and
7007 silc_pkcs_verify_with_hash functions into the file
7008 lib/silccrypt/silcpkcs.[ch].
7010 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7012 * The client entry's userinfo pointer must be always valid.
7013 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
7014 will fail since it requires the userinfo. Now, the userinfo
7015 is allocated as "" if actual userinfo does not exist. Actually,
7016 it must exist and it is totally Ok to drop client connections
7017 that does not announce the userinfo. However, we will make
7018 this workaround for now.
7020 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
7021 to return the remote port by socket.
7023 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7025 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
7026 SILC_SERVER_PENDING_EXEC and added an new macro
7027 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
7028 data or when error occurs while processing the pending command.
7030 Added new argument `destructor' into silc_server_command_pending
7031 and to the SilcServerCommandPending object. This destructor is
7032 now called after calling the pending callback or if error occurs
7033 immediately. If error occurs the actual pending callback won't
7034 be called at all - only the destructor. The destructor may be
7035 NULL if destructor is not needed.
7037 All this applies for client library code as well. Similar
7038 changes were made there as well for the pending commands.
7040 In the client, the application must now allocate the
7041 SilcClientCommandContext with the silc_client_command_alloc
7044 * Added reference counter to the SilcServerCommandContext. Added
7045 function silc_server_command_alloc and silc_server_command_dup
7048 Same type of functions added to the client library for the same
7051 * Removed the cmd_ident from IDListData away since it is now
7052 global for all connections. It is the command identifier used
7053 in command sending and with pending commands. The affected file
7056 * Added reference counter to the SilcSocketConnection objecet to
7057 indicate the usage count of the object. The object won't be
7058 freed untill the reference counter hits zero. Currently only
7059 server uses this, and client ignores it. The client must be
7060 set to use this too later. The affected files are
7061 lib/silccore/silcsockconn.[ch]. Added also the function
7062 silc_socket_dup to increase the reference counter.
7064 This was mainly added because it is possible that the socket
7065 is removed underneath of pending command or other async
7066 operation. Now it won't be free'd and proper DISCONNECTING
7067 flags, etc. can be set to avoid sending data to connection that
7068 is not valid anymore.
7070 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
7071 the connection. After that it sets SILC_SET_DISCONNECTED.
7072 It is, however, possible that the socket data is not still freed.
7073 The silc_server_packet_process now checks that data is not
7074 read or written to connection that is DISCONNECTED. The socket
7075 get's freed when the reference counter hits zero.
7077 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7079 * Changed the client operation API: channel_message operation's
7080 `sender' is now the client entry of the sender, not the nickname
7081 and the `channel' is the channel entry, not the channel name.
7083 In the private_message operation the `sender' is now also the
7084 client entry of the sender not the nickname.
7086 Affected file is lib/silcclient/ops.h and all applications
7087 using the client operations.
7089 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7091 * Moved the calling of ops->connect() from connect_to_server_final
7092 into receive_new_id functin since that is the point when the
7093 client is actually allowed to send traffic to network. The
7094 affected file is lib/silcclient/client.c.
7096 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7098 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
7099 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
7100 (if needs broadcasting) instead of broadcasting the packets one
7101 by one which would make a burst in the network traffic.
7103 * Added `broadcast' argument to the functions in silcd/server.[ch]
7104 silc_server_create_new_channel[_with_id] to indicate whether
7105 to send New Channel packet to primary router.
7107 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7109 * Added new function into the silcd/server.[ch] files:
7110 silc_server_create_new_channel_with_id to create new channel with
7111 already existing Channel ID.
7113 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
7114 lib/silccore/silcpacket.h. This packet is used t send list of
7115 Set Mode payloads inside one packet. Server uses this to set
7116 the modes for the channels and clients on those channels, that it
7117 announced to the router when it connected to it. The protocol
7118 specification has been updated accordingly.
7120 * The silc_server_new_channel did not handle the packet coming
7121 from normal server as it normally does not send that. However,
7122 when it announces its channels it does send it. Implemented
7123 the support for that.
7125 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
7126 into the file lib/silccore/id.h.
7128 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7130 * Fixed memory leaks in the functions silc_idlist_del_client,
7131 silc_idlist_del_channel and silc_idlist_del_server in the file
7132 silcd/idlist.c. All of those leaked like a sieve.
7134 * Fixed some small memory leaks in the client's function
7135 silc_client_notify_by_server.
7137 * Added functions into silcd/server.c: silc_server_announce_clients,
7138 silc_server_announce_channels and silc_server_announce_server.
7139 These functions are used by normal and router server to announce
7140 to its primary router about clients, channels and servers (when
7141 router) that we own. This is done after we've connected to the
7144 These functions effectively implements the following packet types:
7145 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
7146 and SILC_PACKET_NEW_ID_LIST.
7148 * Added new functions into the silcd/packet_receive.[ch]:
7149 silc_server_new_id_list, silc_server_new_channel_list and
7150 silc_server_new_channel_user_list to handle the incoming
7151 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
7153 * Added support of changing Channel ID in the function
7154 silc_server_replace_id. If the server that announces a channel
7155 to the router already exists in the router (with same name but
7156 with different Channel ID), router is responsible to send
7157 Replace ID packet to the server and force the server to change
7158 the Channel ID to the one router has.
7160 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
7161 client that the Channel ID has been changed by the router. The
7162 normal server sends this to the client. Client must start using
7163 the new Channel ID as the channel's ID.
7165 Implemented handling of this new type into lib/silcclient/client.c
7166 into the function silc_client_notify_by_server.
7168 * Added new function silc_idlist_replace_channel_id into the files
7169 silcd/idlist.[ch] to replace the Channel ID.
7171 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7173 * Call silc_server_command_identify_check always when processing
7174 the IDENTIFY command in silcd/command.c
7176 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7178 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
7179 send keepalive packets. The packet can be sent by clients,
7180 servers and routers.
7182 Added function silc_socket_set_heartbeat into the file
7183 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
7184 If not set, the heartbeat is not performed. The actual
7185 heartbeat is implemented in the low level socket connection
7186 library. However, application is responsible of actually
7189 Added silc_server_send_heartbeat to send the actual heartbeat
7190 packet into silcd/packet_send.[ch]. Server now performs
7191 keepalive with all connections.
7193 * Added silc_task_get_first function into lib/silcutil/silctask.c
7194 to return the timeout task with shortest timeout. There was a bug
7195 in task unregistration that caused problems. TODO has been
7196 updated to include that task system must be rewritten.
7198 * The client library will now resolve the client information when
7199 receiving JOIN notify from server for client that we know but
7200 have incomplete information.
7202 * Rewrote parts of silc_server_remove_from_channels and
7203 silc_server_remove_from_one_channel as they did not remove the
7204 channel in some circumstances even though they should've.
7206 * Encryption problem encountered in server:
7208 The LEAVE command used to send the Channel Key packet to the
7209 router immediately after generating it. However, the code
7210 had earlier sent Remove Channel user packet but not immediately,
7211 ie. it was put to queue. The order of packets in the router
7212 was that Channel Key packet was first and Remove Channel User
7213 packet was second, even though they were encrypted in the
7214 reverse order. For this reason, MAC check failed. Now, this
7215 is fixed by not sending the Channel Key packet immediately but
7216 putting it to queue. However, this is more fundamental problem:
7217 packets that are in queue should actually not be encrypted
7218 because packets that are sent immediately gets encrypted
7219 actually with wrong IV (and thus MAC check fails). So, packets
7220 that are in queue should be encrypted when they are sent to
7221 the wire and not when they put to the queue.
7223 However, the problem is that the current system has not been
7224 designed to work that way. Instead, the packet is encrypted
7225 as soon as possible and left to the queue. The queue is then
7226 just purged into wire. There won't be any fixes for this
7227 any time soon. So, the current semantic for packet sending
7230 o If you send packet to remote host and do not force the send
7231 (the packet will be in queue) then all subsequent packets to the
7232 same remote host must also be put to the queue. Only after the
7233 queue has been purged is it safe again to force the packet
7236 o If you send all packets immediately then it safe to send
7237 any of subsequent packets through the queue, however, after
7238 the first packet is put to queue then any subsequent packets
7239 must also be put to the queue.
7241 Follow these rules and everything works fine.
7243 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7245 * Added new function silc_server_remove_clients_by_server to
7246 remove all client entries from ID list when the server connection
7247 is lost. In this case it is also important to invalidate all
7248 client entires as they hold the invalid server entry. This
7249 fixes fatal bug when server has lost connection and will reconnect
7252 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7254 * Made some sanity checks to silc_server_daemonise like to check
7255 whether the requested user and group actually exists.
7257 * Added sanity check to SKE's silc_ske_responder_finish to check
7258 that the public and private key actually is valid.
7260 * Invalidate the client's nickname when receiving Replace ID
7261 packet and the Client ID is being replaced. This means that the
7262 server will query the nickname if someone needs it (client)
7265 * Sort the ID Cache in client library when the ID Cache data
7266 has changed (needs sorting).
7268 * Do not allow for SILC client to create several connections to
7269 several servers. The client does not support windows right now
7270 and generating multiple connections causes weird behaviour.
7272 Irssi-silc client does support windows and can handle several
7273 connections without problems, see: www.irssi.org and SILC plugin.
7275 * Fixed some places where client was added to the IDList. The
7276 rule of thumb is following (in order to get everything right):
7277 If the client is directly connected local client then the
7278 `connection' argument must be set and `router' argument must be
7279 NULL to silc_idlist_add_client function. If the client is not
7280 directly connected client then the `router' argument must
7281 bet set and the `connection' argument must be NULL to the
7282 silc_idlist_add_client function.
7284 * The funtion silc_server_packet_send_local_channel actually did
7285 not check whether the client was locally connected or not. It
7286 does that now. Fixed a bug related to LEAVE command.
7288 * Fixed Remove Channel User payload parsing bug in server's
7289 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
7291 * The server's silc_server_save_channel_key now checks also the
7292 global ID list for the channel as it might not be in the local
7293 list. Fixed a bug related to LEAVE command.
7295 * Is this the end of the [<unknown>] buglet that has been lurking
7296 around for a long time? A little for loop fix in server's
7297 silc_server_command_whois_parse that is used by both IDENTIFY
7298 and WHOIS command. At least, this was a clear bug and a cause
7299 of one type of [<unknown>] buglet.
7301 * WHOIS and IDENTIFY commands call the function
7302 silc_server_command_[whois/identify]_check function even if
7303 we are not router server.
7305 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7307 * Added --with-gmp configuration option. If set the GMP
7308 is always compiled in the SILC source tree. If not set then
7309 it is checked whether the system has the GMP3 installed. If
7310 it has then the GMP won't be compiled (the system's headers
7311 and library is used), if it doesn't have it then the GMP is
7312 compiled in the SILC source tree.
7314 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7316 * Changed RSA private exponent generation to what PKCS #1
7317 suggests. We try to find the smallest possible d by doing
7318 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
7319 not security fix but optimization.
7321 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7323 * Added new config entry [Identity] to fork the server and run
7324 it as specific user and group. A patch from Bostik.
7326 * Imported Dotconf configuration library into lib/dotconf.
7327 This will be used to create the SILC configuration files later.
7328 It will appear in the distsribution after this commit.
7330 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7332 * A big code auditing weekend happening. Auditing code for
7333 obvious mistakes, bugs and errors. Also, removing any code
7336 Removed files for being obsolete:
7338 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
7339 inline in the file lib/silcutil/silcbuffer.h)
7341 o lib/silcutil/silcbufutil.c (the header has inline versions)
7343 Changed code to fix possible error conditions:
7345 o The buffer formatting routines now check that the destination
7346 buffer really has enough space to add the data. This applies for
7347 both buffer formatting and unformatting
7348 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
7349 unformatting was changed to accomodate following rules:
7350 XXX_*STRING_ALLOC will allocate space for the data into the pointer
7351 sent to the function while XXX_*STRING will not allocate or copy
7352 the data into the buffer. Instead it sets the pointer from the
7353 buffer into the pointer sent as argument (XXX_*STRING used to
7354 require that the pointer must be allocated already). This change
7355 makes this whole thing a bit more consistent and more optimized
7356 (note that the data returned in the unformatting with XXX_*STRING
7357 must not be freed now). The routines return now -1 on error.
7359 o Tried to find all code that use buffer_format and buffer_unformat
7360 and added return value checking to prevent formatting and
7361 especially unformatting errors and possible subsequent fatal
7364 o Changed ske->x and ske->KEY to mallocated pointers in
7365 lib/silcske/silcske.h. Fixed possible data and memory leak.
7367 o Added return value checking to all *_parse* functions. Fixed
7368 many memory leaks as well.
7370 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
7371 so that buffer overflows would not happen. All code now also
7372 checks the return value as it can fail.
7374 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7376 * Added reconnection support to server if the normal server looses
7377 its connection to the router (for example if router is rebooted).
7378 The server performs normal reconnection strategy implemented
7379 to the server. Affected file silcd/server.c.
7381 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7383 * Added new packet type SILC_PACKET_SET_MODE that is used to
7384 distribute the information about changed modes (for clients,
7385 channels and clients channel modes) to all routers in the
7386 network. Updated the protocol specification accordingly.
7388 Added functions into silcd/packet_send.c and
7389 silcd/packet_receive.c: silc_server_send_set_mode,
7390 silc_server_set_mode.
7392 Added new files silcmode.[ch] into lib/silccore that implements
7393 the encoding and decoding of Set Mode Payload. Added new type
7394 SilcSetModePayload. Moved the definitions of different modes
7395 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
7397 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7399 * Oops, a little mistake in server's connection authentication
7400 protocol. The protocol is not ended with FAILURE but with
7401 SUCCESS if the authentication is Ok. :) Affected file is
7404 * Implemented NICK_CHANGE notify handling in server in the file
7405 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
7406 the local clients on the channel. After the changing nickname
7407 in router environment snhould work and the [<unknown>] nickname
7408 should appear no more.
7410 The silc_server_replace_id function that receives the Replace ID
7411 payload now sends the NICK_CHANGE notify type also in the file
7412 silcd/packet_receive.c
7414 * Changed WHOIS and IDENTIFY command to support the maximum amount
7415 of arguments defined in protocol specs (3328 arguments). This
7416 fixed a bug that caused problems when there were more than three
7419 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7421 * Added extra parameter, command identifier, to the
7422 silc_client_send_command so that explicit command identifier
7425 Changed that ID list routines uses specific command identifier
7426 when sending WHOIS/IDENTIFY requests to the server so that they
7427 can be identified when the reply comes back.
7429 Affected files lib/silcclient/command.[ch],
7430 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
7432 * Added `sender' argument to silc_server_packet_send_to_channel
7433 to indicaet the sender who originally sent the packet to us
7434 that we are now re-sending. Ignored if NULL. Affected file
7435 silcd/packet_send.[ch].
7437 * Added some server statistics support in silcd/server_internal.h
7438 SilcServerStatistics structure and around the server code. Also
7439 send some nice statistics information when client is connecting
7442 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7444 * Fixed channel ID decoding in server's JOIN command reply in
7445 silcd/command_reply.c
7447 * Fixed braodcasting of replace ID payload to not to send it if
7448 we are standalone server in silcd/packet_receive.c.
7450 * Fixed all channel message sending routines to not to send
7451 packets to clients that has router set, since they are routed
7452 separately in the same function earlier. Affects file
7453 silcd/packet_send.c and all channel packet sending functions.
7455 * In USERS reply, res_argv[i] are not allocated, the table
7456 is allocated. Thus changed that free the table, not its
7459 * In server's whois_check and identify_check if the client is
7460 locally connected do not send any WHOIS commands - they are not
7463 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7465 * Fixed some minor bugs in client when sending WHOIS command. The
7466 arguments was in wrong order.
7468 * Removed statis function add_to_channel from server in
7469 silcd/command.c that was previously used with the joining but
7472 * Tested USERS command in router environment successfully with two
7473 routers, two servers and two clients.
7475 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7477 * Reorganized the USERS command and command reply in client library
7478 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
7479 When the command is given by user we register a pending command
7480 callback that will reprocess the command after the reply has been
7481 received from the server. When reprocessing the packet we then
7482 display the information. Thus, the USERS information is displayed
7483 now in the command callback instead of in the command reply
7484 callback. The processing of the command is same as previously
7485 when server has sent the command reply in the JOINing process.
7487 * Added to USERS command in silcd/command_reply.c to join the client,
7488 we didn't use to know about, to the channel after we've created
7489 a client entry for it. Also, for clienet we did know already still
7490 check whether it is on the channel or not and add it if not.
7492 * Removed silc_server_command_join_notify as the function and its
7495 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7497 * Changed the client's pending command handling to the same as the
7498 server's pending command handling. It is also now possible to
7499 execute command reply functions from other command reply
7500 function as the function callbacks for commands and command
7501 replies are one and same. The pending commands are not static
7502 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
7503 in client connection context. Thus, pending commands are server
7504 connection specific as it is convenient.
7506 Changed the function silc_client_command_pending and
7507 silc_client_command_pending_del and added new function
7508 silc_client_command_pending_check. Removed the
7509 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
7512 * Added cmd_ident, current command identifier, to the client
7513 connection context in lib/silcclient/client.h to keep track on
7514 command identifiers used in command sending. Client's command reply
7515 function handling now supports the mandatory command identifiers.
7517 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
7518 funtions in client to fully support pending command callbacks.
7520 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
7521 as one of the arguments to the application in the command reply
7524 * NOTE: The FORWARDED flag is depracated. It used to be depracated
7525 before first releasing SILC but came back. Now it is removed again
7526 and should come back nomore. The FORWARDED flag was used only
7527 by the JOINing procedure by forwarding the command packet to router.
7528 Now, the JOINing procedure has been changed to more generic (due
7529 to various router environment issues) and FORWARDED is not needed
7530 anymore for anything. The protocol specification is yet to be
7533 Now, removed silc_server_packet_forward from server and the flag
7534 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
7536 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7538 * Renamed NAMES command to USERS command. The NAMES was named that
7539 due to historical reasons. Now it is renamed. Also, rewrote
7540 parts of the USERS command. The nickname list is not sent anymore
7541 by the server. Only Client ID and mode lists are sent in the USERS
7542 command. Changed this also to the protocol specification.
7544 The client now resolves the names and stuff after it receives
7545 the USERS list from the server when joining to the channel.
7547 * WHOIS and IDENTIFY commands has been changed to support multiple
7548 Client ID's per command. One can now search for multiple users
7549 in the network by sending only one WHOIS or IDENTIFY command.
7550 Changed the code and the protocol specifications.
7552 * Removed silc_server_command_identify_parse and changed that IDENTIFY
7553 uses silc_server_command_whois_parse to parse the request. */
7555 * If normal server, do not parse the WHOIS and IDENTIFY requests
7556 before sending it to the router. Saves some time.
7558 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7560 * Fixed JOIN command on client library. Wrong number of arguments
7561 used to crash the client.
7563 * Added silc_server_channel_has_global function to check whether
7564 channel has global users or not.
7566 * Added silc_server_channel_has_local function to check whether channel
7567 has locally connected clients on the channel.
7569 * The silc_server_remove_from_one_channel now checks whether the
7570 channel has global users or not after given client was removed from
7571 the channel. It also checks whether the channel has local clients
7572 on the channel anymore. If it does not have then the channel entry
7573 is removed as it is not needed anymore.
7575 * The silc_server_notify now checks on JOIN notify whether the joining
7576 client is one of locally connected or global. If it is global then
7577 the channel has now global users on the channel and that is marked
7578 to the channel entry. Also, it now saves the global client to
7579 global list who is joining and JOINs it to the channel. This is
7580 for normal server, that is.
7582 Changed silc_server_send_notify_on_channel,
7583 silc_server_packet_relay_to_channel and
7584 silc_server_packet_send_to_channel check if we are normal server
7585 and client has router set (ie. global client) do not send the
7586 message to that client, as it is already routed to our router.
7588 * Implemented LEAVE notify type handling in silc_server_notify
7591 * Tested LEAVE command in router environment successfully. Tested
7592 with two routers, two servers and two clients.
7596 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
7598 * Implemented SIGNOFF notify type handling in silc_server_notify
7601 * silc_server_remove_id now removes the client entry from all channels
7602 it has joined and thusly sends SIGNOFF notify type.
7604 * Rewrote the NAMES list generation in server by removing two excess
7605 loops. The lists are created now inside one loop.
7607 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7609 * silc_server_remove_channel_user checks now also global list
7610 for channel and client.
7612 * silc_server_new_channel_user checks now both local and global
7613 list for channel and client. Fixed a bug in client id decoding.
7614 Used to decode wrong buffer.
7616 * silc_server_channel_message checks now both local and global
7617 list for channel entry.
7619 * Tested channel joining (hence JOIN) in router environment
7620 successfully. Tested with two routers, two servers and two
7623 * Tested channel message sending in router environment successfully.
7625 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7627 * Added silc_server_save_channel_key into server.[ch] to save the
7628 received channel key in Channel Key payload processing. It is
7629 also used in JOIN command reply handling.
7631 Equivalent function silc_client_save_channel_key added into
7632 client.[ch] into client library.
7634 * Changed JOIN command reply to send information whether the channel
7635 was created or not (is existing already) and the channel key
7636 payload. Changed protocol specs accordingly.
7638 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
7639 the request was sent by ID and not by nickname. Crashed on
7642 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7644 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
7645 now correctly save the received data.
7647 * silc_server_free_sock_user_data now notifies routers in the
7648 network about entities leaving the network.
7650 At the same time implemented functions silc_server_remove_id
7651 and silc_server_send_remove_id to receive and send REMOVE_ID
7652 packets. The packet is used to notify routers in the network
7653 about leaving entities. The ID removed will become invalid in
7656 * Added function silc_idlist_del_server into server. Removes and
7657 free's server entry from ID list.
7659 * silc_server_private_message function now checks, if we are router,
7660 that the destination ID really is valid ID, naturally.
7662 * In router when NEW_ID packet is received (for new client) the
7663 hash of the Client ID is saved in the ID Cache but the
7664 client->nickname is set to NULL, instead of putting the hash
7667 IDENTIFY command now also checks that client->nickname must be
7668 valid. If it is not if will request the data from the server who
7669 owns the client. Added new function
7670 silc_server_command_identify_check.
7672 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
7673 to set the command to already allocated Command Payload.
7675 * Tested private message sending in router environment with two
7676 routers, two servers and two clients. Fixed minor bugs and now
7679 * Fixed segfault from client's NAMES command. Used to crash if
7682 * Forwarded packets must not be routed even if it is not destined
7683 to the receiver. Changed server code comply with this.
7685 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7687 * Added `require_reverse_mapping' boolean value to ServerParams
7688 structure. If TRUE (not default) the server will require that
7689 the connecting host has fully qualified domain name.
7691 If the reverse mapping is not required and hostname could not be
7692 found the IP address is used as hostname.
7694 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7696 * Implemented version string checking to both client and server.
7697 The check is incomplete currently due to the abnormal version
7698 strings used in development version of SILC.
7700 * Changed all command functions in server to use the new
7703 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7705 * Changed char *data to unsigned char *data in ID Cache system to
7706 support binary data as ID Cache data. Changed code to support
7707 binary data in lib/silccore/idcache.c.
7709 * Renamed silc_server_packet_relay_command_reply to
7710 silc_server_command_reply as it is normal packet receiving
7711 function. Rewrote the function to accept command replys for
7712 servers and not only for clients.
7714 * Mark remote router always as registered server if we are connecting
7715 to it. Otherwise, commands sent by the router to us are ignored.
7717 * All ID List find routines now returns the ID Cache Entry pointer
7718 as well if requested.
7720 * WHOIS command works now in router environment, tested with two
7721 routers, two servers and two clients.
7723 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
7724 in router environment (as it is almost equivalent to WHOIS) but
7725 hasn't been tested thoroughly. Added new functions:
7727 silc_server_command_identify_parse
7728 silc_server_command_identify_send_reply
7729 silc_server_command_identify_from_client
7730 silc_server_command_identify_from_server
7732 * Disabled route cache adding because adding two different ID's with
7733 same IP replaces the old cache entry thus giving wrong route.
7734 The entry->router->connection is always the fastest route anyway
7735 so route cache may not be needed. Of course, new routes maybe
7736 established after receiving the ID when the entry->router->connection
7737 might not be anymore the most optimal.
7739 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7741 * Add route cache for received ID for fast routing.
7743 * Added silc_server_packet_route to route received packet on router
7744 that is not destined to us.
7746 * Renamed silc_server_get_route to silc_server_route_get.
7748 * Added id_string and id_string_len fields into SilcServer to
7749 include encoded ServerID for fast comparing without excess
7750 encoding of the ID's.
7752 * Cleaned up WHOIS command on server side. Added following static
7755 silc_server_command_whois_parse
7756 silc_server_command_whois_check
7757 silc_server_command_whois_send_reply
7758 silc_server_command_whois_from_client
7759 silc_server_command_whois_from_server
7761 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
7762 arguments in command replies. All command functions should be
7763 updated to use this macro.
7765 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7767 * Minor typo fixes on command reply handling on server.
7769 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7771 * Added silc_server_command_add_to_channel internal routine to add
7772 the client to the channel after router has created the channel and
7773 sent command reply to the server.
7775 * Added generic silc_server_send_command to send any command from
7778 * Use static buffer with ID rendering instead of duplicating data.
7780 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7782 * Fixed a channel user mode bug when joining to a channel server gave
7783 everybody channel founder rights, oops.
7785 * We mark ourselves as the router of the incoming server connection
7786 if we are router ourselves. This way we can check in some packet
7787 sending functions whether it is locally connected server. For
7788 incoming router connections we put NULL.
7790 * For router sending packets locally means now always sending the
7791 packet cell wide; to local clients and local servers. For normal
7792 server sending packet locally means sending it to only local
7795 * Fixed the JOIN command to really work in router environment. If the
7796 channel is created it is always created by the router. Router is
7797 also responsible of making the initial joining to the channel,
7798 sending JOIN notify to the sending server and distributing
7799 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
7800 does not exist server doesn't do anything else but forward the
7801 command to the router which performs everything.
7803 * Added silc_server_send_channel_key function to send the Channel Key
7806 * Added silc_server_create_channel_key to create new channel key. The
7807 channel key is now re-generated everytime someone joins or leaves
7808 a channel, as protocol dictates. Note: channel->key_len is the
7811 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7813 * Splitted server.[ch] finally. Created now packet_send.[ch] and
7814 packet_receive.[ch] to separate packet sending and receiving
7815 routines. The server.[ch] now includes everything else including
7816 actual packet processing (writing and reading data) and other
7819 Renamed silc_server_private_message_send_internal to
7820 silc_server_send_private_message. The routine is still though
7821 used only to relay private messages as server does not send
7822 private messages itself.
7824 Renamed silc_server_new_channel to silc_server_create_new_channel
7825 and added new function sicl_server_new_channel that handles the
7826 incoming New Channel packet. Added also new sending function
7827 silc_server_send_new_channel to send New Channel Payload.
7829 * Added new function silc_server_notify to process incoming notify
7830 packet to the server/router. Server may then relay the notify
7831 to clients if needed.
7833 * Added new function silc_server_new_channel_user to process incoming
7834 New Channel User packet. Router will redistribute the packet and
7835 send JOIN notify to its local clients and locally connected servers
7836 if needed. Normal server will send JOIN notify to its local client
7837 on same channel when received this packet. Added also corresponding
7838 sending function silc_server_send_new_channel_user to sent the
7841 * Added boolean route argument to send_notif_to_channel and
7842 packet_send_to_channel functions to attempt to route the packet
7843 if it is TRUE and send only locally if it is FALSE.
7845 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7847 * silc_server_replace_id now broadcasts the received replace ID
7848 packet if it is not broadcast packet already. The router must
7849 broadcast to inform other routers about changed ID.
7851 * Added backpointer to server's router into SilcServer context in
7852 silcd/server_internal.h.
7854 * Fixed silc_server_packet_broadcast to send correct broadcast
7857 * The channel key is now distributed to the local client as soon
7858 as it is received from the router (in router environment) so that
7859 no other packet may be sent for the channel until client has
7862 * silc_server_remove_channel_user now broadcasts the received
7863 Remove Channel User packet if it is not broadcast packet already.
7864 The router must broadcast to inform other routers about removed
7867 * Added users field into SilcPacketContext that is a reference count
7868 of the context. One can increase the reference count by calling
7869 silc_packet_context_dup which is now changed to just increase the
7870 reference count instead of duplicating the data. The reference
7871 count is decresed by calling silc_packet_context_free that will
7872 free the data after the reference count hits zero.
7874 For now on the packet context and everything allocated into it
7875 (including the raw packet from network) must be freed by calling
7876 the new silc_packet_context_free function. Added also new function
7877 silc_packet_context_alloc that must be used now to allocate the
7878 context. This also means that if a routine is asynchronous from
7879 silc_[client/server]_packet_parse_type the packet context must
7880 be duplicated by calling silc_packet_context_dup. Otherwise it
7881 gets free'd after silc_[client/server]_packet_parse_type returns.
7882 Also, one must remember that if packet is duplicated then its
7883 reference count must be decresed by calling the free function as
7884 many times as it was duplicated.
7886 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7887 from both client and server.
7889 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7891 * Made joining to a channel working in router environment.
7893 * Cleaned up JOIN command on server side and create function
7894 silc_server_command_join_channel internal routine to make the
7897 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7899 * Changed silc_command_pending list to SilcDList. Also, added
7900 `ident' field to SilcServerCommandPending structure to identify
7901 the reply and to call correct callback.
7903 Added silc_server_command_pending_check function to replace the
7904 corresnponding macro. The silc_command_pending list is not
7907 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7908 to set identifier to previously allocated Command Payload. It
7909 is used to set identifier for command when resending Command
7912 * Added silc_command_payload_encode_payload to encode Command
7913 Payload buffer from SilcCommandPayload structure.
7915 * Added silc_argument_payload_encode_payload to encode Argument
7916 payload buffer from SilcArgumentPayload structure.
7918 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7920 * Changed WHOIS command to support router connection on server side.
7921 The whois request is always sent to router unless the server is
7922 standalone server. After server has received the reply from the
7923 router will it send the reply to the client.
7925 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7926 broadcast received broadcast packet. The function is used only
7927 by router. The broadcast packet is always sent to the router's
7930 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7931 render given ID to printable string, for log files for example.
7933 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7935 * Made basic router to router connections working. At least they
7936 can now connect to each other but nothing really works the way
7937 they are supposed - yet.
7939 * Added new initiator token to RouterConnection configuration
7940 file in silcd/serverconfig.[ch]. It is used to tell whether we
7941 are the initiator to the remote router or whether we'll expect
7942 the other end to connect.
7944 * Moved registering of listener task to silc_server_init, hence
7945 the server starts listenning as soon as it is run, even if it
7946 does not have connections to other routers. Let's see how well
7949 * Changed default connection retry timeouts for more suitable in
7952 * Removed cipher and such arguments from silc_idlist_add_client
7953 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7954 Added new function silc_idlist_add_data to add the keys and stuff
7957 * Added SilcIDListData structure and added it to SilcClientEntry
7958 and SilcServerEntry as their first field in the structure. This
7959 way we can explicitly cast the ID entries to the SilcIDListData
7960 structure and get common data for the entries. In past, we had
7961 to first check what type of connection it is and then cast it to
7962 correct ID entry type. Now, we can directly cast the opaque
7963 pointer to the SilcIDListData (no matter what ID entry it actually
7964 is) and get the data needed.
7966 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7968 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7969 in some circumstances even if threre were timeout tasks, though not
7970 IO tasks, but tasks anyway. Now fixed.
7972 * Defined SilcServerConnection structure to hold connection specific
7973 stuff about directly connected servers and routers. The definition
7974 is currently in silcd/server_internal.h. I thought about having
7975 a bit more important role fro this struct but for now it is used
7976 only when connecting to other server (or router actually).
7978 * Added connecting retry support in server when connecting to
7979 router(s). The retry feature implement exponential backoff
7980 algorithm. Also, added SilcServerParams structure to hold default
7981 parameters for server. For now, it include these retry settings
7982 and are hard coded. After server is moded to be as Silc Server
7983 Library this structure will be more important.
7985 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7987 * Changed client librarys channel->clients table to SilcList and
7988 changed code accordingly.
7990 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7992 * Changed client's channel table to SilcList and changed code
7993 accordingly. Also changed SilcChannelClientEntry to include back-
7994 pointer to the channel so that client entry can use that structure
7995 as list as well and we have fast cross-reference to the channel.
7996 This change dramatically decreased the complexity of channel
7997 handling with client entry and vice versa (removed one extra
7998 loop when searching for channel entry from many functions).
8000 * Changed server->sim from table to SilcDList and changed code
8003 * NAMES command can now be used from user interface. It will show
8004 the user list on the channel, neatly.
8006 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
8007 Code now saves realname of the user if it becomes available.
8009 * Renamed configure.in to configure.in.pre and made ./prepare
8010 script to automatically add correct version string to
8011 configure.in which it creates from configure.in.pre.
8013 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8015 * NAMES command reply now shows users mode with the nickname when
8018 * Moved silc_client_ch[u]mode[_char] functions from
8019 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
8020 place sucks, they are utility functions and should be in some
8023 * Fixed some unsigned int's to unsigned short's. Patch by cras.
8025 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
8028 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8032 * Added TRQ (efficient deque and list library) into lib/trq. This is
8033 a very good list library that is currently used in the SILC. Defined
8034 SilcList API over the library because I didn't like the API very
8035 much. See lib/trq/silclist.h for the API and examples of how to
8036 use the API. Fixed various places in the code to use the new
8037 SilcList API. The SilcList is meant for lists that has a structure
8038 already defined as a list. It is not suitable to add just some
8039 context to the list (in TRQ, the context is the list actually).
8041 So, I defined SilcDList that can be used for the purpose where
8042 predefined list structure does not exit. This can be used as
8043 such list. Now some context just can be added to the SilcDList.
8044 Currently this list is not used in the SILC just yet, though there
8045 are a lot places where this can replace dynamically allocated
8046 tables and I will fix these places, later, to use SilcDList.
8047 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
8048 and use TRQ internally).
8050 Also fixed some annoying warning messages that the original TRQ
8051 code generated. Also minor changes to TRQ's Makefile.in.
8053 * Added support for querying by Client ID to both WHOIS and
8054 IDENTIFY commands into server, as required by the protocol.
8056 * Removed method function pointers from SilcBuffer structure. They
8057 weren't used to anything and just increased the context size for
8058 no good reason. This change also made silc_buffer_alloc and
8059 silc_buffer_free functions inline functions.
8061 * Disabled command flooding detection support until it's fixed so
8062 that it accepts commands in but does not execute them more than once
8065 * Added silc_net_localhost(), to return local hostname, into
8066 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
8067 that must be initialized before calling silc_client_init.
8069 * Added new function: silc_server_send_notify_on_channels to send
8070 notify messages to all channels client has joined. It is assured
8071 that the message is sent only once per client.
8073 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
8074 lib/silcutil/silcutil.[ch] as silc_format function. The new
8075 function is generic and is used by server as well, not only by
8076 the logging routines.
8078 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
8079 the provided version string was not acceptable. Added new function:
8080 silc_ske_check_version into lib/silcske/silcske.h. The function
8081 must be implemented by the application (client or server) and it
8082 does not reside in the SKE library. The function checks the version
8083 string remote end sent.
8085 * Added back pointers (to opaque context and to SilcSocketConnection)
8086 into SilcPacketContext structure into lib/silccore/silcpacket.h.
8088 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
8089 duplicate packet context structure.
8091 * Changed `notify' client operation to send same arguments as client
8092 receives from server except for ID's. ID's are mapped to correct
8093 ID entry and that is returned. Also, if channel entry is not sent
8094 by server but the notify is for channel the channel entry is sent
8095 to application (otherwise application doesn't know that it is for
8096 channel (library gets it from packet's Destination ID)).
8098 * Added silc_client_remove_from_channels into client library to
8099 remove a client from all channels it has joined to. Used when
8100 received SIGNOFF notify from server. Added also new function
8101 silc_client_replace_from_channels to replace old ID entry with
8102 new ID entry on all channels. Used when received NICK_CHANGE
8105 * Fixed ID Cache list handling in silc_idlist_get_client in
8106 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
8107 to get (or query) client by ID.
8109 * Updated TODO list.
8111 * Added connection authentication status message defined by the
8112 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
8113 support for these into the code in client and server side.
8115 * Added generic function silc_client_send_command to send any command
8116 with variable argument list. Application should use this function
8117 to send commands if the command functions provided by the library
8118 does not suite for the application's user interface needs.
8120 * Added new `failure' client operation. Application is notified about
8121 received failure packet if client is executing a protocol. In this
8122 case the protocol's execution has failed.
8124 * Added SKE's end notify to send the SKE_SUCCESS notify message that
8125 is required by the protocol.
8127 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
8128 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
8131 * Added status flag to SilcSKE object to indicate realtime status
8132 of the SKE protocol.
8134 * Application receives now exactly same command reply arguments as
8135 the library receives from server. However, if ID is received the
8136 corresponding ID entry is returned to the application (eg. Client
8137 ID is mapped to correct SilcClientEntry entry and that is returned).
8138 Changed command_reply client operation due to this change.
8140 * Changed all ID's in commands and in command replys as ID Payloads.
8141 Change affected both client and server side codes.
8143 All ID's sent in SILC network (with execption of ID's in SILC
8144 Packet header) are sent in ID Payload to support variable length
8147 * Server now notifies nick changes and notifies all clients on
8148 the channels about the new nickname (about the new Client ID,
8151 * Implemented CMODE command to change channel modes. Supports all
8152 channel modes defined by the protocol specs except ban and invite
8153 lists. (Also, private channel key mode is supported but support for
8154 setting private channel key in client is missing, thus, this mode
8155 has no effect on client side (except that server requires that the
8156 client uses private channel key and normal channel traffic does not
8159 Also, invite mode works per se, but INVITE command does not work
8160 yet correctly, so you can set channel as invite only channel but
8161 inviting clients to the channel does not work (it is yet to be
8162 thought what's the best way to do it).
8164 * Added new command SILC_COMMAND_CUMODE to change user mode on the
8165 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
8166 Implemented CUMODE command to change user's mode on the channel.
8167 Supports all modes defined by the protocol specs.
8169 * Added NAMES command reply to return users modes on the channel.
8171 * Removed unnecessary and slow ciphers from lib/silccrypt.
8173 * Set SO_KEEPALIVE option to connection sockets by default.
8175 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
8177 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
8178 redefined the Notify Payload into protocol specs.
8180 * Added silc_id_payload_parse_id to get ID directly from raw
8183 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8185 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
8186 accept searching by Client ID as well.
8188 * Added support for LEAVE and SIGNOFF notify types in client library.
8190 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
8191 to parse ID Payload from raw data.
8193 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8195 * Added flags parameter into silc_ske_assemble_security_properties
8196 function in lib/silcske/silcske.[ch].
8198 * Changed notify client operation to fit better for notify messages
8199 sent by server. The notify payload received from server is now
8200 passed to the application (after parsing it to SilcNotifyPayload).
8201 It is application's responsibility to retrieve the arguments
8202 from the payload and show the message the way it wants. The message
8203 sent by server is implementation specific.
8205 * Changed public keys to comply with the protocol specification.
8206 Old public keys are not supported anymore and are not compatible.
8208 * Removed nickname from Channel Payload as the latest draft removed
8209 it. The client must resolve the nickname from the NAMES command
8210 reply received when it joined the channel.
8212 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
8214 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8216 * Fixed some errors in protocol specification drafts.
8218 * Created lib/silccore/silcnotify.c to implement Notify Payload
8219 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
8220 generic payloads described by protocol specifications. The file
8221 includes implementations for ID Payload and Argument Payload.
8223 * Changed Command Payload implementation to use the new Argument
8224 Payload. Changed command_xxxx_payload to command_payload_xxxx
8225 to comply with SILC coding conventions.
8227 * Added suppport for Argument Payload handling in Notify Payload
8228 implementation as protocol requires it. Added the new support
8229 into server and client lib as well.
8231 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8233 * Added support for multiple nicknames on same channel. [n] is
8234 added locally to the nickname if there are more than one same
8235 nicknames on the channel.
8237 * Server now sends all nicknames that matched WHOIS request.
8238 Client also shows the list received from server.
8240 * Added TOPIC command to client side. User can now set and show
8241 current topic on channel.
8243 * Added MOTD command to client and server. Also, server sends the
8244 motd when client connects to the server.
8246 * Changed version strings to comply ISO 8601.
8248 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8250 * Fixed protocol error handling in client library. It should now
8251 cope even if the SKE fails for some reason.
8253 * Made new protocol specification drafts for submitting to IETF.
8255 * Implemented TOPIC command to server in silcd/command.c.
8257 * Added two new notify types into lib/silccore/silcnotify.h:
8258 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
8259 notify nickname change and topic setting/change on a channel.
8261 * API change of command_reply operation in client library. The
8262 application gets now the status type received from server as well.
8264 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8266 * Removed the function just added to lib/silcutil/silcschedule.[ch].
8268 * Cras fixed and optimized the packet handling even further and
8269 it should work now. Minor change to the prototype of function
8270 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
8272 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8274 * Added new function into lib/silcutil/silcschedule.[ch]:
8275 silc_schedule_with_fd to select() a specified fd. The function
8276 returns after timeout expires or data arrives or goes. The
8277 function is used by packet routines to wait that all data is
8278 received from network.
8280 * Fixed data reading from network in lib/silccore/silcpacket.c.
8281 The code now assures that all data is read from the fd and then
8282 continues packet processing. This was a bug fix since the code
8283 used to drop some data in some circumstances.
8285 * Added new function into lib/silcclient/client.[ch]:
8286 silc_client_start_key_exchange to start key exchange after
8287 connection has been established to server. The code internally
8288 now uses this funtion but its main purpose was to provide it
8289 for applications that perform their own connecting. After
8290 application has created a connection it merely calls this
8291 function to start the key exchange between client and server.
8292 The library takes care of everything else after that.
8294 Updated also lib/silcclient/README to explain the usage of
8297 * Do not send to application information that connection has
8298 been established. Application gets notified it by connect
8301 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8303 * Applied cras's patch to add silc_schedule_one function. The
8304 function runs scheduler once and returns.
8306 * Fixed the scheduler after cras messed it up. The timeout
8307 handling works now as it's supposed to work.
8309 * Added into lib/silccore/ silcnotify.h to include notify
8310 message types support. Changed silc_server_send_notify*
8311 functions, in server.[ch], to support those new notify types.
8312 Added the support for the notify types into client library,
8313 as well. Added new notify client operation into ops.h in
8316 * Changed silc_server_packet_send_to_channel to send normal
8317 packets instead of just channel message packets. The function
8318 is now used to send the notify packets to channels. It is not
8319 used to send channel message packets anymore, as server never
8322 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
8323 va_arg()s as it seems to require it nowadays. I guess, if SILC
8324 is compiled with older va_arg() the new code should work anyway.
8326 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8328 * Splitted core library. Core library (lib/silccore) includes
8329 now only SILC protocol specific core (and common) components.
8330 Created new utility library (lib/silcutil) that includes more
8331 generic purpose stuff. The stuff for util library was taken
8332 from the old core library. This was minor and easy split.
8334 * Created SILC Client Library (lib/silcclient) that includes
8335 implementation of the SILC client without user interface. This
8336 was major move from silc/ directory. The code has been changed
8337 so that it is transparent towards the user interface. The
8338 silc/ directory includes now the same user interface as before
8339 and it uses the new client library. Read lib/silcclient/README.
8340 Basicly, the client library performs everything else related
8341 to SILC except user interface handling. Also, configuration
8342 files are considered to be part of user interface and library
8343 does not handle them.
8345 This change also changed a lot of structures, function naming etc.
8346 Most important change was that SilcClientWindow object was
8347 renamed to SilcClientConnection in the client library. Created
8348 also new file lib/silcclient/ops.h. Also added new files
8349 silc/local_command.[ch] and silc/client_ops.[ch].
8351 All these changes were made to make it easier for user interface
8352 designers to create what ever user interface for the SILC client
8355 It is also expected that the server will be moved to lib
8356 directory as well and SILC Server Library will be created;
8357 sometimes in the future.
8359 * Removed Local commands from lib/silccore/silccommand.h as
8360 they are application specific and new client library does not
8361 handle any of those anymore.
8363 * Several functions moved to lib/silcutil/silcutilc.[ch] from
8364 old client implementation in silc/.
8366 * Added support for callback functions in SILC_LOG_* macros.
8367 Application can now set its own callbacks that will be called
8368 instead of using the default functions that will always print
8369 the debug messages to stderr (or stdout). Also, debugging can
8370 now be disabled by setting silc_debug to FALSE and re-enabled by
8371 setting it to TRUE. Note, that logging will still work even
8372 if debugging is disabled.
8374 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
8375 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
8376 silc_log_reset_debug_callbacks.
8378 * To enable debugging in silc client one must give now -d
8379 option on command line.
8381 * Changed silc_schedule_init to automatically allocate task queues
8382 if they are not allocated before calling it.
8384 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8386 * Added GMP 3.1 into math library.
8388 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8390 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
8391 a channel in SILC network. The packet is used by servers and
8392 routers to notify other routers that user has left a channel.
8393 This little feature was missing until now. Added the feature
8394 to protocol specification as well.
8396 Added functions: silc_server_send_remove_channel_user and
8397 silc_server_remove_channel_user into server.[ch].
8399 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
8400 lib/silccore/silcpacket.h. However, they are not implemented
8403 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8405 * Fixed joining to a channel and sending channel messages
8406 between server and router. The channel message sending should
8407 now work inside a cell.
8409 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8411 * Fixed the private message sending between server and router.
8412 The private message sending should now work inside a cell.
8414 * Added silc_server_replace_id into server.[ch] to replace
8415 existing ID in the SILC network.
8417 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
8418 and silc_idlist_replace_server_id into idlist.[ch] in server.
8420 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8422 * Fixed the server to server connections. Server can again now
8423 connect to router. Router to router connections probably does
8426 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8428 * Added dynamic protocol registering support. Now protocols can
8429 registered and unregistered on the fly. Patch by cras.
8431 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8433 * Added lib/contrib directory to hold routines that some platforms
8434 don't have but are needed by SILC.
8436 * Added getopt.c, getopt1.c and getopt.h from GNU C library
8437 into lin/contrib to provide getopt() and getopt_long() for
8438 those who don't have it.
8440 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8442 * Added AWAY command to client. When away message is set and
8443 client receives a private message packet the client automatically
8444 replies to the sender with the away message.
8446 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
8447 bug seemed to be the cause of recent problems when compiling
8450 * Added version detection support to SKE protocol specification
8451 and added the new changes to the SKE implementation as well.
8452 There were other minor changes in the SKE protocol as well.
8454 Many changes in lib/silcske/silcske.[ch] and in
8455 lib/silcske/payload.[ch].
8457 * Added ^U functionality, clear input line. Patch from cras.
8459 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8461 * Mainly small bugfixes on core library. Fixed some debugging
8462 logging and buffer overflow in silclog.c.
8464 * Updated config.sub and config.guess on the distribution tree.
8466 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8468 * Added command lagging support in server. Client may execute
8469 commands now only once in two seconds.
8471 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8473 * Optimized packet reception. MAC computation and checking is now
8474 also more optimized. A lot previously duplicated code is now
8475 used as generic by both client and server.
8477 * Fixed key pair generation in clientutil.c
8479 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8481 * Added into lib/silccore/silcbufutil.[ch] new function;
8482 silc_buffer_realloc.
8484 * Moved generic packet sending/encryption functions to
8485 lib/silccore/silcpacket.[ch] from client and server. Some
8486 rewriting of the functions.
8488 * Moved all generic packet reception/decryption functions to
8489 lib/silccore/silcpacket.[ch] from client and server. The
8490 packet processing is now much cleaner in both client and server.
8491 These were major changes in both client and server.
8493 * Created many common functions in server to do packet sending.
8494 Previously code were duplicated a lot, this has been removed
8497 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8499 * Rewrote major parts of the ID cache system. Don't know
8500 whether it is better now or not but at least the API is more
8503 * Major rewrite on ID cache stuff on client because of the ID
8504 cache API changes. Added idlist.c to client.
8506 * Also major rewrite on ID cache stuff on server as well.
8507 Major rewrite of idlist.[ch]. SilcXXXList's are now named
8508 SilcXXXEntry's. We won't keep anymore idlist specific pointers
8509 in hand, instead they are all put into the ID cache system now.
8510 All server_idlist_* routines uses ID cache now instead of
8511 traversing its own lists (those lists does not exist anymore).
8512 SilcIDList though still exists. Also, SilcXXXEntry's are
8515 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8517 * Finally made the SKE implementation compliant to the protocol
8518 specification. All mp integers are now binary encoded as
8519 opposed being HEX encoded.
8521 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
8524 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
8525 functions: silc_[encode/decode]_pem. Also added function
8526 silc_encode_pem_file to PEM encode with newlines ('\n') for
8529 * SILC public keys are now encoded either PEM or binary. Same
8530 option is for private keys as well. By default private keys
8531 are binary encoded and public keys PEM encoded. Silly HEX
8532 encoding were removed.
8534 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
8535 function to create fingerprints.
8537 * Fixed a bug in SHA1; does not change the original data anymore.
8539 * Partly implemented INFO command on client and server side.
8540 Fixed CLEAR command. Changes to SERVER command; show current
8541 server(s) when giving command without arguments. Added
8542 VERSION command to client.
8544 * Added check to server that unregistered connections cannot
8545 execute commands (unless it is specificly allowed).
8547 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8549 * Fixed screen refresh.
8551 * Fixed channel joining bug from client. On some circumstances
8552 client tried to join to a channel it had already joined.
8554 * Added public key verification process into client's protocol.c.
8555 The client now verifies the public key from user and saves
8556 it into ~./silc/serverkeys/ directory.
8558 Added into: clientutil.[ch]: silc_client_verify_server_key.
8560 * Changed SKE protocol's silc_ske_initiator_finish function
8561 to accept callback function that verifies the received public
8562 key. Removed old silc_ske_verify_public_key function.
8564 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8566 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
8567 silc_pkcs_private_key[_data]_set.
8569 * Made the password and public authentication more cleaner in
8570 server's protocol.c.
8572 * Removed historic and obsolete protocol `channel_auth' from
8573 both client and server.
8575 * Removed wrong way of sending command status messages from
8576 server to client in server's command.c. The old way violated
8577 protocol specification.
8579 Changes to silccore/silccommand.[ch]: removed
8580 silc_command_encode_status_payload -> not needed anymore,
8581 changed silc_command_encode_payload_va to accept extra
8582 argument on variable argument list. The argument type must
8583 now be provided to the function. Also, added new function:
8584 silc_command_encode_reply_payload_va which is same as
8585 normal command_encode_payload_va except command status type
8586 is provided as extra argument.
8588 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8590 * Added ~./silc directory handling. The directory includes the
8591 public and private keys for the client.
8593 Added silc_client_check_silc_dir, silc_client_create_identifier
8594 and silc_client_load_keys.
8596 * Implemented SILC protocol compliant public key. Added public
8597 and private key saving to and loading from files.
8599 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
8600 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
8601 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
8602 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
8603 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
8605 Implemented: silc_pkcs_save_[public/private]_key[_data] and
8606 silc_pkcs_load_[public/private]_key.
8608 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8610 * Added silc_server_get_route (route.[ch]) to get connection
8611 data for the fastest route for given ID.
8613 * Implemented INVITE command on client and server. The command
8614 were re-defined in the SILC Protocol Specification and the
8615 implementation now complies with the specification.
8617 * Implemented PING command on client and server.
8619 * Implemented NAMES command on client and server. The server side
8620 supports currently only normal server not router server yet.
8621 Some changes to NAMES definition in SILC protocol specification.
8623 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8625 * Implemented LEAVE command on client and server.
8627 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
8628 again. This change was made to the protocol as well. Server
8629 should not violate the protocol specification anymore.
8631 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8633 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
8634 was tested. SOCKS4 was not but should work anyway.
