536 * Save the channels list in WHOIS command reply in normal server
537 so that WHOIS always shows joined channels also in normal
538 server and not just on router. Affected file is
539 silcd/command_reply.c.
541 Thu Apr 11 22:29:33 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

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

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

631 lib/silccore/silcmode.h, irssi/src/silc/core/client_ops.c,
632 irssi/docs/help/in/umode.in and lib/silcclient/command.c.
634 Sun Apr 7 17:07:59 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
636 * Added STATS command to the protocol after all, to return
637 various statistical information about the network. It can
638 be used by clients to retrieve statistical information, and
639 servers may use it to to fetch cell and network wide
640 statistics from router. Updated the protocol specs and
641 implemented it to the server. Protocol TODO #16.
642 Affected files are lib/silccore/silccommand, silcd/command.[ch],
643 silcd/command_reply.[ch].
645 Sat Apr 6 17:08:58 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
647 * The LIST command reply in client libary now adds new channel
648 entry if the returned channel doesn't exist yet in cache,
649 and returns the channel entry to the application in the
650 command_reply client operation. Affected file is
651 lib/silcclient/command_reply.c.
653 * Changed the channel message payload's MAC generation to
654 include the IV in the MAC as well. This way all relevant
655 parts of the channel message payload are authenticated also
656 with the channel message MAC (and not only by packet MAC).
657 Causes incompatibility with 1.0 protocol. Protocol TODO #7.
658 Affected file is lib/silccore/silcchannel.c.
660 * Fixed the SKE to save the remote version, since the
661 silc_ske_parse_version mistakenly checked wrong version,
662 after it replaced the start payload. Affected files are
663 lib/silcske/silcske.[ch].
665 Fri Apr 5 16:03:03 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
667 * Splitted lib/silcutil/silcutil.h into silcstrutil.h for
668 string utility functions. Added there also new functions
669 silc_utf8_[encode/decode/valid] for UTF-8 string encoding.
670 Affected files lib/silcutil/silcstrutil.[ch].
672 * Renamed silc_*_pem functions to silc_pem_* functions. Affected
673 files are lib/silcutil/silcstrutil.[ch].
675 * Defined that the security property fields in SKE SHOULD be
676 UTF-8 encoded, defined that version string MUST be US-ASCII
677 encoded, defined that passphrases sent in connection
678 authentication protocol MUST be UTF-8 encoded. Implemented
679 these to the client and server. Defined also that other
680 passphrases sent in the protocol MUST be UTF-8 encoded.
681 Affected files are lib/silcske/silcske.c,
682 lib/silcclient/protocol.c, silcd/protocol.c,
683 silcd/serverconfig.c, and lib/silccore/silcauth.c.
685 * Changed the silc_client_close_connection interface to not
686 need the SilcSocketConnection which should not be visible
687 to application. Affected files are lib/silcclient/client.c
688 and lib/silcclient/silcclient.h.
690 * Rewrote the text for Private Message Key Payload in the
691 protocol specification. Protocol TODO #11.
693 Wed Apr 3 16:24:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
695 * Upgraded the protocol version to 1.1, updated protocol specs
698 * Added the nickname as new argument to NICK_CHANGE notify and
699 added it to protocol specs and implemented it to client and
700 server. Protocol TODO #3. Affected files are silcd/idlist.[ch],
701 silcd/command.c, silcd/packet_receive.c, packet_send.[ch], and
702 lib/silcclient/client_notify.c.

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

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

813 silc_hash_register, silc_hmac_register and silc_pkcs_register
814 to const. Affected files are lib/silccrypt/silccipher.[ch],
815 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
817 * Changed the silc_get_username and silc_get_real_name to
818 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
820 * Fixed the Irssi SILC Client to use the silc_get_username and
821 silc_get_real_name insted of glib routines since the glib
822 routines only corrupt stack. Fixes the Irssi SILC to work in
823 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
825 * Fixed the Irssi to not use g_get_home_dir since it crashes
826 or returns garbage on cygwin and corrupts stack. Added function
827 get_home_dir to Irssi routines. Affected files are
828 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
830 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
832 * Made some structure optimizations. SFTP memory FS MemFSEntry
833 entry structure. Optimized SilcTask structure. Optimized
834 SilcPacketContext structure.
836 Affected files lib/silcsftp/sftp_fs_memory.c,
837 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
839 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
841 * And yet again reverted back the config thing since Johnny
842 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
845 * Fixed memory leaks from config object. Affected files are
846 silcd/serverconfig.[ch].
848 * Added support for adding new connections to the server in rehash.
849 After rehash they take effect.
851 Added support for changing the maximum allowed connections in
852 rehash. The number can grow but going smaller is not supported.
854 Added function silc_server_num_sockets_by_remote to the
855 silcd/server_util.[ch].
857 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
859 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
861 * Added preliminary checking during config parsing for a valid
862 public/private key and removed further checks in the code.
863 Affected files are silcd/serverconfig.[ch], server.c.
865 * Moved functions silc_server_drop() and silc_server_daemonise()
866 from server.c to silcd.c since they are stricly related to
867 the application activity.
869 * Reverted a small part of the automatic ref/unref since
870 it caused a double unref in some situations. Affected
871 files are silcd/silcd.[ch], server.c, serverconfig.c.
873 * Added some .cvsignore files in the lib directory.
875 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
877 * Fixed silc_net_gethostbyaddr to correctly resolve by
878 address. Affected file lib/silcutil/silcnet.c.
880 * Fixed the notify relaying to client. The HMAC to be used
881 with relayed packets ws wrong and caused decryption failure
882 at the client end. Affected file is silcd/packet_receive.c.
884 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
886 * Created new branch silc_protocol_1_0_branch.
888 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
890 * Changed the silc_server_config_* routines to be SilcServer
891 independent. They are now officially application specific code
892 and not part of generic server implementation. Affected files
893 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
895 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
897 * Added automatic referencing of config context in the
898 silc_server_config_alloc, and automatic unreferencing in the
899 silc_server_config_destroy. Affected files are
900 silcd/serverconfig.[ch], silcd/silcd.c.
902 * Fixed the silc_log_quick handling in the logging routines.
903 It didn't log quickly when it was TRUE. Affected file is
904 lib/silcutil/silclog.c. Also the flush delay was set even
905 if it was 0 in config file. Affected file is
906 silcd/serverconfig.c.
908 * Added support for changing key pair of the server in rehash.
909 Affected file silcd/server.c.
911 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
913 * Fixed the TOPIC_SET notify to not cras. It changed the topic
914 too early, before getting the channel entry. Affected file
915 is silcd/packet_receive.c.
917 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
919 * Added functions silc_server_config_[ref/unref], these are used
920 to prevent that the config object is destroyed.
922 No longer directly affect global variables silc_log_quick and
923 silc_log_delay, they are first cached inside the config object
924 and then applied with silc_server_config_setlogfiles().
926 silc_server_config_set_defaults() is now internal to
927 serverconfig.c, there are no reasons to show this internal stuff
930 Affected files are silcd/serverconfig.[ch].
932 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
933 fprintf's to stderr, since some code may be executed again after
934 the server went into the background. Affected files are
937 * Added rehash support. Added function silc_server_rehash() that
938 will perform all the basic tasks of the rehashing procedure.
940 * Added command line option `-x, --hexdump'. This will enable the
941 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
942 The option `--hexdump' implies `--debug'.
944 * Fixed a bad bug in the logging APIs (silcutil library) where
945 the application would crash after calling silc_log_reset_all().
947 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
949 * Fixed the KICKED notify handling in client library to
950 correctly remove the channel and all entries from the
951 channel when I was kicked. This bug crashed the client.
953 Fixed yet another but in KICKED notify handling to remove
954 the kicked client correctly from the channel.
956 Affected file is lib/silcclient/client_notify.c.
958 * Fixed a minor bug in looking up correct client entry
959 in KICKED notify in server. Affected file is
960 silcd/packet_receive.c.
962 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
963 sources correctly to distribution. Fixes --with-gmp option.
965 * Removed the manual rehashing from ID Cache, and changed it
966 to use the SILC Hash Table's auto rehash feature. Affected
967 file is lib/silccore/silcidcache.c.
969 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
971 * Fixed a bug in the silc_client_nickname_format function that
972 handles the multiple same nickname formatting. Two clients
973 with same nickname caused problems after the first one left
974 and rejoined. It didn't format the nickname correctly.
975 Affected file is lib/silcclient/idlist.c.
977 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
979 * Don't change the topic if olod topic is same as new one.
980 Affected file is silcd/packet_receive.c.

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

1000 now returns the type of the ID to the sent pointer. Affected
1001 file is lib/silccore/silcid.[ch].
1003 * Added check for CMODE_CHANGE notify type that mode change is
1004 allowed by the sender. Affected file silcd/packet_receive.c.
1006 * Added check for CUMODE_CHANGE notify type that mode change is
1007 allowed by the sender. Affected file silcd/packet_receive.c.
1008 Added the ID type as CUMODE_CHANGE notify type as argument
1009 to the `notify' client operation. Affected files are
1010 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
1012 * Added function silc_client_add_server to the client library.
1013 Added support for resolving also channel and server info when
1014 received unknown entity in notify packet. Affected files are
1015 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
1017 * Added function silc_command_get_status to return the command
1018 status from the command reply's argument payload. Affected files
1019 are lib/silccore/silccommand.[ch].
1021 * Added check for KICKED notify type that the kicking is
1022 allowed by the client. Affected file silcd/packet_receive.c.
1024 * Created function silc_get_input which can be used to get input
1025 (echo on or off) from user on command line. Affected files are
1026 lib/silcutil/silcutil.[ch].
1028 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1030 * Optimized silc_server_packet_relay_to_channel function.
1031 Added new function silc_channel_message_payload_encrypt which
1032 can be called directly if channel message payload needs to
1033 be encrypted and is already encoded (no need to call _encode
1034 function). Packet relaying is now done by router without any
1035 extra memory allocations. Affected files are
1036 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
1037 silcd/packet_send.c.

1047 the client. Affected file silcd/packet_receive.c.
1049 * Changed the silc_server_client_on_channel to return the
1050 SilcChannelClientEntry as well. Moved the function
1051 silc_server_check_cmode_rights to server_util.[ch].
1052 Affected files are silcd/server_util.[ch], silcd/command.c.
1054 * Added function silc_server_check_umode_rights to check whether
1055 changing client's user mode is allowed. Added check for
1056 UMODE_CHANGE notify type that the umode change is allowed
1057 by the client. Affected files are silcd/server_util.[ch],
1058 silcd/packet_receive.c and silcd/command.c.
1060 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1062 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
1063 ID length. It ignored that ID can be IPv6 based as well.
1064 Affected file lib/silccore/silcpacket.h.
1066 * Fixed the silc_id_id2str and silc_id_str2id to take the
1067 IPv6 address offset's into consideration. Affecte file is
1068 lib/silccore/silcid.c.
1070 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1072 * Fixed the internal Unix scheduler functions to check for
1073 NULL context they may receive. The affected file is
1074 lib/silcutil/unix/silcunixschedule.c.
1076 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
1078 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
1079 can specify different directory with --home command line
1080 parameter. Affected files irssi/src/silc/core/client_ops.c,
1083 * SILC-specific commands aren't now executed if the active server
1084 isn't of SILC-type, so there won't be problems with having
1085 IRC and SILC protocol support in same client. Affected files
1086 irssi/src/silc/core/silc-channels.c, silc-servers.c,
1089 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1091 * Improved the signal support in SILC Schedule. Added new
1092 function silc_schedule_signal_call which is used by application
1093 to mark a signal to be called. It is now safe to perform
1094 any kind of tasks in signal callbacks since it is guaranteed
1095 that the application specified signal callback is called
1096 after the signal is over. Affected files are
1097 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
1099 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1101 * Added `name' field to SilcChannelPrivateKey to represent
1102 application given name for the key. Moved also the context from
1103 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
1104 Added the `name' argument also to the function
1105 silc_client_add_channel_private_key.
1107 Added function silc_client_current_channel_private_key to set the
1108 current channel private key in use.
1110 Added "change" command to KEY command which can be used to change
1111 the current channel private key. Bound the command also to
1112 alt+K (Alt+Shift+k).
1114 Also affected files lib/silcclient/client_channel.c,
1115 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
1117 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1119 * Added silc_rng_get_byte_fast function in to the
1120 lib/silccrypt/silcrng.[ch].
1122 * Changed the interface of silc_packet_assemble and the
1123 silc_packet_send_prepare. If silc_packet_assmble is now
1124 called the application does not call silc_packet_send_prepare
1125 because the library will call it automatically. These
1126 interfaces now also return a reference to the outgoing buffer
1127 which includes the assembled packet, which the application can
1128 use to encrypt the packet.
1130 Affected files are lib/silccore/silcpacket.[ch],
1131 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
1132 silcd/packet_send.c, server_backup.c and packet_receive.c.
1134 * Fixed a packet sending bug on very high load, where outgoing
1135 packet queue wasn't handled correctly and packets got corrupted.
1136 Affected files are lib/silcutil/*/silc*sockconn.c,
1137 lib/silcclient/client.c and silcd/server.c.
1139 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1141 * Added macro SILC_PACKET_DATALEN which can be used during
1142 packet assembling to check whether the data to be added to
1143 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
1144 len is truncated until it fits it.
1146 Added checks for maximum length of channel message payload and
1147 private message payload also.
1149 Added checks for maximum packet length in server and in
1152 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
1153 lib/silcclient/client.c, lib/silccore/silcchannel.c and
1154 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
1155 lib/silcclient/client_prvmsg.c.
1157 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1159 * Added silc_server_packet_queue_purge call to the
1160 silc_server_disconnect_remote to assure that all data in the
1161 queue before disconnecting is sent to the network. Affected
1162 file silcd/server.c.
1164 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1166 * Added the deleting of server's own ID cache entry to the
1167 silc_server_free function. Free also everything else that
1168 has been allocated in silc_server_init. The affected file
1171 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1173 * Added functions silc_parse_version_string, silc_version_to_num,
1174 and silc_ske_parse_version to parse SILC protocol style version
1175 strings. Affected files lib/silcutil/silcutil.[ch] and
1176 lib/silcske/silcske.[ch].
1178 * Added new configuration params: version_protocol, version_software
1179 and version_software_vendor to specify what version the remote
1180 host must at least be to be able to connect to server. The vendor
1181 string can be regex matched too. Added new function
1182 silc_server_connection_allowed to check maximum number of allowed
1183 connections, and allowed versions for incoming connections.
1184 Affected files are silcd/server.c, server_util.[ch] and
1187 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1189 * Added preliminary support for signals in scheduler. The
1190 signals we care about are now blocked always when the scheduler
1191 is locked. This way we can synchronise the use of signal with
1192 scheduler. It is guaranteed that when signal occurs the scheduler
1193 is not locked, and thus new tasks can be safely added to the
1196 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
1197 to silc_schedule_internal_init and silc_schedule_internal_uninit.
1198 Added new platform specific routines
1199 silc_schedule_internal_signals_[un]block and
1200 silc_schedule_internal_signal_[un]register.
1202 Added new functions to SILC Schedule API:
1203 silc_schedule_signal_[un]register. Each signal that application
1204 is going to use should be registered to the scheduler.
1206 Affected files are lib/silcutil/silcschedule.[ch],
1207 lib/silcutil/*/silc*schedule.c.
1209 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1211 * Check for unauthenticated client and server in the
1212 silc_server_new_client and silc_server_new_server functions.
1213 Affected file silcd/packet_receive.c.
1215 * Added function silc_string_is_ascii to check whether given
1216 string is 7-bit ASCII string. Affected files are
1217 lib/silcutil/silcutil.[ch].
1219 * Added function silc_id_is_valid_server_id into the
1220 silcd/serverid.c and added checking for valid Server ID's in
1221 silc_server_new_server. The Server ID must always be based
1222 on the server's public IP address.
1224 * Added logging of DISCONNECT packet message in the server.
1225 Affected file silcd/server.c.
1227 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1229 * Changed all library interfaces that use Global RNG to also
1230 accept SilcRng as argument. Affected files are
1231 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
1232 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
1233 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
1234 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
1235 lib/silccrypt/rsa.c.
1237 * Added function silc_pkcs_generate_key to the
1238 lib/silccrypt/silcpkcs.[ch] for applications so that they
1239 don't need to do pkcs->pkcs->init calls anymore.
1241 * Remove SilcSocketConnection from the SFTP API since it really
1242 wasn't needed there. The application has the information
1243 saved in its contexts anyway and the SFTP layer doesn't need
1244 know about it. Affected files lib/silcsft/silcsftp.h and
1245 lib/silcsftp/sftp_[server/client].c.
1247 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
1248 The SilcSimContext is not SilcSim.
1250 * Fixed possible buffer overflows in silc_id_render in the
1251 lib/silcutil/silcutil.c.
1253 * On EPOC the global crypto module lists are not used at all
1254 in the crypto library. Added support for using the constant
1255 algorithm list on EPOC. Affected files are
1256 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
1259 * Fixed the handling of third parameter of KICKED notify, since
1260 it was mistakenly updated to SILC Protocol 1.0 even though it
1261 is to be included in 1.1. Since it is not in 1.0 it is not
1262 mandatory, and this fix now handles it only if it is provided,
1263 and it is not error if it is not provided. Affected file
1264 lib/silcclient/client_notify.c.
1266 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1268 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
1269 client. Affected file irssi/src/silc/core/client_ops.c.
1271 * Merged with Irssi 0.8.4 from irssi.org CVS.
1273 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1275 * Check for valid socket connection in client entries before
1276 sending any messages. Fixes a crash, but doesn't fix some
1277 other underlaying bug that is lurking there. Affected
1278 file silcd/packet_send.c.
1280 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
1282 * $usermode, $cumode and $cumode_space expandos shouldn't do
1283 anything with non-SILC server records. Affected file
1284 irssi/src/silc/core/silc-expandos.c
1286 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1288 * Fixed the silc_net_check_[host/local]_by_sock to support
1289 IPv6 bound sockets as well. Now they can return IPv6 addresses
1290 as well. Affected file lib/silcutil/silcnet.c.
1292 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
1293 Affected lib/silcutil/unix/silcunixnet.c.
1295 * Fixed ID rendering (at least on some platforms, not NetBSD)
1296 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
1298 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1300 * Added silc_hash_public_key and silc_hash_public_key_compare
1301 functions to be used with SilcHashTable. They can be used to
1302 hash public keys and compare public keys in hash table. Affected
1303 file lib/silcutil/silcutil.[ch].
1305 * Added support for specifying multiple public keys for Client
1306 connection section in server configuration file. This makes it
1307 possible to accept multiple public keys from same host, or to
1308 make a section that accepts any incoming host, and have the
1309 accepted public keys listed in the section.
1311 Added functions silc_sever_[find/get]_public_key, added the
1312 support for this actually to all connection sections but only
1313 the Client section is currently allowed to specify multiple
1316 Affected files are silcd/server.c, server_internal.h,
1317 command.c, protocol.c, server_util.[ch], packet_receive.c.
1319 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1321 * Merged Irssi 0.8.2 from irssi.org CVS.
1323 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1325 * If silc_debug is TRUE, also output standard logging messages
1326 to stderr with the debug output.
1328 Made silc_log_reset_all() flushing all channels before returning.
1329 Also fixed some documentation typos.
1331 Affected files are lib/silcutil/silclog.[ch].
1333 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1335 * Fixed the server to check correctly the amount of connections
1336 from single host, by checking also the type of the connection.
1337 Fixed also the comparison of number of connections and number
1338 of allowed connections. Affected files are silcd/server.c,
1341 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1343 * Fixed the USERS command reply to save the user's mode on the
1344 channel as well. Fixed JOIN command reply to check whether a
1345 client is on channel already and not join it twice. Affected
1346 file lib/silcclient/command_reply.c.
1348 * Added new file silc-expandos.c into irssi/silc/core/ to return
1349 various stuff for various signal for the statusbar etc. updating.
1350 Now Irssi SILC client prints channel user modes etc. on the
1353 * The user mode (like server/router operator changes) is now shown
1354 on the Irssi SILC client's statusbar. The affected files are
1355 irssi/src/silc/core/client_ops.c, silc-expandos.c.
1357 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1359 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
1360 to SILC_SCHEDULE_[UN]LOCK macros.
1362 * Added more error printing to logs in server code. Affected
1363 files silcd/server.c and silcd/protocol.c.
1365 * Fixed -S option parsing in Irssi SILC Client. Affected file
1366 irssi/src/silc/core/silc-core.c.
1368 * Added silc_buffer_alloc_size function. Affected file is
1369 lib/silcutil/silcbuffer.h.
1371 Tue Mar 5 14:37:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1373 * Changed all silc_[hash|hmac|cipher|pkcs]_default tables to
1374 constants. Affected files in
1375 lib/silccrypt/silcpkcs.[ch], silchash.[ch], silchmac.[ch] and
1378 * Changed the internal SFTP Memory FS table to const. Affected
1379 file lib/silcsftp/sftp_fs_memory.c.
1381 Sun Mar 3 18:37:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1383 * Fixed the buffer formatting and unformatting routines to
1384 check the size of 64 bits types with sizeof(). Affected
1385 file is lib/silcutil/silcbuffmt.c.
1387 Mon Feb 25 17:19:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1389 * Removed 0.6.x backwards support.
1391 Sun Feb 24 12:53:25 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1393 * Changed all integer type names:
1394 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
1395 to avoid collisions with other libraries using same type names
1398 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1400 * Added `prefer_ipv6' argument to the functions
1401 silc_net_gethostbyname[_async]. If it is TRUE it will return
1402 IPv6 address over IPv4. If FALSE IPv4 address is returned
1403 even if IPv6 address was found. Affected files
1404 lib/silcutil/silcnet.[ch].
1406 * Added support silc_net_create_connection[_async] to fallback
1407 to IPv4 address if IPv6 address could not be used (like if
1408 it doesn't work on a specific system). Affected file in
1409 lib/silcutil/unix/silcunixnet.c.
1411 Sat Feb 23 15:20:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1413 * Added silc_schedule_reinit function to do the enlarging
1414 of the max tasks handling capabilities of the scheduler.
1415 Affected files lib/silcutil/silcschedule.[ch].
1417 Wed Feb 20 20:41:01 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1419 * Added automatic extern "C" { ... } for C++ compilers so the
1420 application does not need to define them. Affected file
1421 includes/silcincludes.h.
1423 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
1424 old name went against naming convention. Applications now
1425 include "silcclient.h" instead of "clientlibincludes.h".
1426 Removed includes/clientlibincludes.h, it is redundant now.
1428 * Renamed includes/version.h to silcversion.h.
1430 * Added really preliminary support for OS/2 into the util
1431 library. Only thread & mutex API is implemented, others
1432 are still to be implemented. Created the lib/silcutil/os2/
1433 directory. Created also file includes/silcos2.h.
1435 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1437 * Added preliminary BeOS support into the util library.
1438 Created lib/silcutil/beos/, and implemented all the needed
1439 functions to support SILC on BeOS. Created also file
1440 includes/silcbeos.h.
1442 Mon Feb 18 15:49:22 EET 2002 Timo Sirainen <tss@iki.fi>
1444 * Added proper initializations to silc's irssi code, so it's
1445 now possible to load it as module. Affected files
1446 irssi/src/silc/core/silc-core.c,
1447 fe-common/silc/fe-common-silc-core.[ch] and fe-text/silc.c
1449 Sun Feb 17 19:02:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1451 * Merged latest Irssi (0.8.1) from the irssi.org's CVS into
1454 * Fixed the silcdoc document generator to correct generate
1455 docs from all kinds of filenames. Affected files are
1456 util/robodoc/Source/generator.c, scripts/silcdoc/silcdoc
1458 * ROBOdoc documented lib/silcutil/silcmemory.h.
1459 Added also new function silc_memdup.
1461 * Removed lib/silcutil/silcbufutil.h and moved those routines
1462 to the lib/silcutil/silcbuffer.h.
1464 Sun Feb 17 15:52:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1466 * Added `user_count' to the SilcChannelEntry which now tells the
1467 number of users on the channel. The user count is now saved
1468 in normal server of global channels as well. Affected files
1469 silcd/server.c, idlist.h, packet_receive.c and command.c.
1471 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
1472 include file utility functions.
1474 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
1475 instead of calling directly OS routines.
1477 * Fixed NICK change printing in Irssi SILC Client. Fixed
1478 KICKED notify printing in Irssi SILC Client. Affected file
1479 irssi/src/silc/core/client_ops.c.
1481 * Fixed a NICK change bug in client library, to not recreate the
1482 client_entry->channels hash table everytime nick is changed.
1483 Affected file lib/silcclient/client.c.
1485 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1487 * ROBOdoc documented the lib/silcske/silcske.h, and improved
1488 the SKE interface a bit.
1490 * Fixed padding problem in PKCS#1. The padding was not actually
1491 random since the random number generator was used incorrectly.
1492 This security bug affects only when encrypting with PKCS#1, and
1493 it is not currently used at all in SILC. SILC only use signing
1494 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
1496 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1498 * Rewrote the notify handling in Irssi SILC client to not call
1499 the events as signals. Fixes problems with Perl support.
1500 Affected files irssi/src/silc/core/client_ops.c, silc-channels.c.
1502 * Send the auto-nicking NICK command in client library with
1503 little timeout after connecting. The affected file is
1504 lib/silcclient/client.c.
1506 * Added following new config file settings:
1507 channel_rekey_secs, key_exchange_rekey, key_exchange_pfs,
1508 key_exchange_timeout, conn_auth_timeout, connections_max,
1511 Implemented all the new config settings handling in the server.
1513 Optimized the use of SKE Mutual flag usage. Use it only
1514 if connection authentication protocol is not based in public
1517 Renamed all SilcServerConfigSection* to SilcServerConfig*
1518 to have a bit shorter names.
1520 Affected files silcd/serverconfig.[ch], server.[ch], and
1523 Sat Feb 16 02:46:43 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1525 * Cleaned up the listening sockets code, preparing for the rehash
1526 support. Affected file is silcd/server.c.
1528 * Fixed some output messages. Affected files are silcd/silcd.c,
1531 Fri Feb 15 19:10:20 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1533 * Create lib/doc/silcrng_intro.html document as introduction
1534 to SILC RNG. ROBOdoc documented lib/silccrypt/silcrng.h.
1536 Fri Feb 15 13:23:03 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1538 * Fixes to the silcd config template. Affected file is
1539 doc/example_silcd.conf.in.
1541 * Removed type casts from silc_calloc(), conforming to the
1542 CodingStyle. Affected file is lib/silcutil/silcconfig.c.
1544 * Removed param_name member from client, server, and router
1545 section structs, now identifying the param directly.
1547 Added CONFIG_FREE_AUTH macro in config file parsing.
1549 Affected files are silcd/serverconfig.[ch].
1551 Fri Feb 15 12:24:08 EET 2002 Timo Sirainen <tss@iki.fi>
1553 * Fixed command line parameter handling. All SILC initialization
1554 is now done in silc_core_init() which also fixes autoconnecting
1557 Affected files irssi/src/silc/core/silc-core.c,
1558 irssi/src/fe-text/silc.c.
1560 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1562 * Added new configuration options and blocks:
1563 keepalive_secs, reconnect_count, reconnect_interval,
1564 reconnect_interval_max, reconnect_keep_trying and
1565 require_reverser_lookup. Added ConnectionParam block, and
1566 implemented the connection parameters when connecting as
1567 initiator and when accepting connections as responder.
1569 Added CONFIG_IS_DOUBLE macro in config file parsing, to check
1570 whether given configuration value has been given already.
1572 Affected files silcd/serverconfig.[c], server.[c].
1574 * Splitted the doc/example_silcd.conf.in. Separated the crypto
1575 algorithm parts and created new file silcalgs.conf, that
1576 is now included from the example_silcd.conf.in.
1578 * Optimized the silc_server_connect_to_router_second to take
1579 the connection configuration object from the SilcServerConnection
1580 object instead of finding it during the connecting phase.
1581 Added the configuration object to SilcServerConnection struct.
1582 Affected files silcd/server_internal.h, server.c.
1584 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1586 * Add the client on channel after it was resolved at the
1587 channel message receiving, and it was not already on the
1588 channel. Affected file lib/silcclient/client_channel.c.
1590 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1592 * Fixed the public key authentication to allocate always the

1598 * Unified the serverconfig.[ch]'s helper function interface.
1599 Affected file silcd/serverconfig.[ch].
1601 * Removed doc/example_silc.conf.in since it is redundant.
1602 The make install will now install irssi/silc.conf file.
1604 * Added new Passphrase and Publickey authentication methods to
1605 config file, allowing both public key and passphrase based
1606 authentication to be set at the same time.
1608 Added `prefer_passphrase_auth' setting in config file which
1609 can be used to set to prefer passwd auth if both passwd and
1610 public key is set. If not set, public key is preferred.
1611 This has effect only when being initiator (responder will try
1614 Added support for authentication with passphrase and public key
1615 at the same time. The passphrase is tried first always since
1616 it is faster to check.
1618 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
1620 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1622 * Merged the new SILC Config library, with the server parsing
1623 support. Read the header file silcconfig.h or the toolkit
1624 documentation for the news. Affected files are

1646 * Allow zero length channel messages inside the Channel Message
1647 Payload. Affected file lib/silccore/silcchannel.c.
1649 * Fixed scripts/silcdoc/silcdoc to support all kinds of filenames
1650 as header filenames.
1652 * Removed lib/silcclient/README and created HTML file
1653 lib/silcclient/silcclient_using.html, which is now included
1654 as part of Toolkit documentation.
1656 Thu Feb 7 10:12:25 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1658 * Fixed CUMODE_CHANGE notify handling to change the mode of
1659 correct client. Affected file lib/silcclient/client_notify.c.
1661 * Make silc_rng_alloc fail if it cannot allocate the sha1
1662 hash algorithm. Affected file lib/silccrypt/silcrng.c.
1664 Sun Feb 3 17:20:52 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1666 * Fixed the file transfer's key agreement payload to include
1667 zero port also if the hostname is NULL because it could not
1670 Call file transfer monitor callback now also if error occurs
1671 during key agreement protocol.
1673 Changed the silc_client_file_send interface to return the
1674 SilcClientFileError instead of session id. The session ID
1675 is returned into pointer provided as argument.
1677 Check that the file exists locally before sending the
1678 file transfer request at all.
1680 Affected file lib/silcclient/client_ftp.c, silcapi.h.
1682 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer
1683 error than can occur while key agreement protocol. Affected
1684 file lib/silcclient/silcapi.h.

1690 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
1691 SILC_LOG_WARNING to give out Warning and not Error. Affected
1692 file lib/silcutil/silclog.c.
1694 * Fixed the channel message payload decryption in the function
1695 silc_channel_message_payload_decrypt to not modify the original
1696 buffer before it is verified that the message decrypted
1697 correctly. Otherwise, next time it is called with correct
1698 channel key it won't encrypt since the payload is corrupted.
1699 Affected file lib/silccore/silcchannel.c.
1701 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1703 * Do not constantly resize the window. A fix patch by cras.

1711 Fri Feb 1 22:33:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1713 * Fixed a bug in hash table internal routine for traversing
1714 the table with foreach callback. The current entry may
1715 become invalid in the callback but it was referenced after
1716 the callback returned.
1718 Do not allow auto rehashing of hash table during the
1719 silc_hash_table_foreach operation, for same reasons as it is
1720 not allowed for SilcHashTableList. Affected files are
1721 lib/silcutil/silchashtable.[ch].
1723 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1725 * Defined DLLAPI into silcincludes.h and silcwin32.h for
1726 Win32 DLL. extern's in header files are now declared with
1729 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1731 * Fixed private message handling. It used some old code that
1732 caused the client to crash. Affecte file is
1733 lib/silcclient/client_prvmsg.c.
1735 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1737 * Added function silc_client_add_channel,
1738 silc_client_replace_channel_id, and removed functions
1739 silc_client_new_channel_id and silc_idlist_get_channel_by_id
1740 from client library.
1742 * Added cross reference of the joined channels to the
1743 SilcClientEntry, and changed the SilcChannelEntry's
1744 users list to SilcHashTable. The affected files are
1745 lib/silcclient/idlist.[ch].
1747 * Fixed a bug in hash table tarversing. While the hash table
1748 is traversed with SilcHashTableList the table must not be
1749 rehashed. It is now guaranteed that auto rehashable tables
1750 are not rehashed while tarversing the list. Also defined that
1751 silc_hash_table_rehash must not be called while tarversing
1752 the table. Added function silc_hash_table_list_reset that must
1753 be called after the tarversing is over. The affected files are
1754 lib/silcutil/silchashtable.[ch].
1756 * Changed all hash table traversing to call the new
1757 silc_hash_table_list_reset in server and in client library.
1759 * Added function silc_client_on_channel to return the
1760 SilcChannelUser entry if the specified client entry is joined
1761 on the specified channel. This is exported to application as
1762 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
1764 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1766 * Fixed founder regaining problem with JOIN command on normal
1767 server. The notify for mode change must be sent always and
1768 not only if !cmd->pending. Affected file silcd/command.c.
1770 * Fixed the WHOWAS command's reply sending to support the
1771 lists correctly. Affected file silcd/command.c.
1773 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1775 * When sending JOIN command to router for processing the
1776 sender's old command identifier was not saved back to the
1777 sender's command context, fixed now. The affected file is
1780 * Create the key in JOIN command of the router did not return
1781 the channel key, added check for this. Affected file is
1784 * Fixed a channel ID update bug in JOIN command reply. Do
1785 not directly upgrade the ID but call the function
1786 silc_idlist_replace_channel_id if the ID was changed.
1787 Affected file silcd/command_reply.c.
1789 * Fixed memory leaks from command calling if it would fail.
1790 Affected file silcd/command.c.
1792 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1794 * Applied patches from cras:
1796 Memory leak fixes around libaries, irssi window resize fix,
1797 new silclist.h and silcdlist.h, all extern inline changed to
1800 * Removed dotconf from lib/dotconf, not needed anymore.
1802 * Removed TRQ from lib/trq, not needed anymore.
1804 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
1805 with server connections. Later this will be configurable
1806 in config file after new config file is done. Affected file
1809 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1811 * Fixed a crash in server related to channel announcements.
1812 Affected file silcd/server.c.
1814 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1816 * Fixed memory leaks in silc_server_create_new_channel*
1817 functions. Affected file silcd/server.c.
1819 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
1820 which ID was changed. This way the router will send the
1821 user list for the channel again, and server won't be in
1822 desync in some rare circumstances. Affected file is
1823 silcd/packet_receive.c.
1825 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1827 * Check for NULL socket pointer in the function
1828 silc_server_packet_send_to_channel_real. Affected file
1829 silcd/packet_send.c.

1836 * Fixed some header addition to Toolkit distribution in
1837 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
1839 * Added lib/silcclient/client_ops_example.h as an template
1840 file for application programmers to quickly start using
1841 the SilcClientOperation functions in their application.
1842 Updated the lib/silcclient/README as well to tell about this
1843 nice file made available.
1845 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1847 * Call silc_server_remove_from_channels when removing client
1848 entry when NO_SUCH_CLIENT_ID was received. Affected file
1849 is silcd/command_reply.c.
1851 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1853 * Added server & router operator statistics updating. Affected
1854 file silcd/packet_receive.c and silcd/command.c.
1856 * Fixed the SERVER_SIGNOFF notify handling on normal server
1857 not to save the history information for clients. Same was
1858 fixed earlier in remove_clients_by_server function, but not
1859 here. Affected file silcd/packet_receive.c.
1861 * Raised the default connection-retry count from 4 to 7 in
1862 server. Affected file silcd/server.h.
1864 * Cancel any possible reconnect timeouts when we start the
1865 key exchange. Affected file silcd/server.c.
1867 * Do not reconnect on connection failure when SCONNECT was
1868 given. Affected files silcd/server.[ch].
1870 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1872 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
1874 * Fixed the NICK command to always give the unformatted
1875 nickname to the one giving the NICK command. If unformatted
1876 nickname is cached already it will be formatted and the
1877 local entry will always get the unformatted nickname.
1878 Affected file lib/silcclient/idlist.c.
1880 * Fixed some double frees from client library commands.
1881 Affected file is lib/silcclient/command.c.
1883 * Fixed CUMODE command in server to assure that no one can
1884 change founder's mode than the founder itself, there was a
1885 little bug. Affected file silcd/command.c.
1887 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1889 * Removed the SilcClientCommandDestructor from the client
1890 libary, it is not needed anymore. Affected files are
1891 lib/silcclient/silcapi.h, command[_reply].[ch],
1892 client_notify, idlist.c.
1894 * Fixed GETKEY command to first resolve client, and then
1895 resolve the server only if the client was not found, instead
1896 of resolving both at the same time. Affected file is
1897 lib/silcclient/command.c.
1899 * Added silc_client_start_key_exchange_cb and lookup the
1900 remote hostname and IP address before starting the key
1901 exchange with server. The affected file is
1902 lib/silcclient/client.c.
1904 * The server's public key is now saved using the IP address
1905 of the server and not the servername for the filename.
1906 The hostname public key filename is checked as an fall back
1907 method if the IP address based filename is not found.
1909 Fixed the GETKEY command to save the fetched server key
1910 in correct filename.
1912 Print the remote server's hostname now when new key is
1913 received during connection process. Affected file is
1914 irssi/src/silc/core/client_ops.c.
1916 * Return always our own public key to the client if it asks
1917 for it with GETKEY command. Affected file silcd/command.c.
1919 * Removed the use_auto_addr variable from default config
1920 file since it was in wrong section. Affected file is
1923 * Fixed TOPIC_CHANGE notification to not route it when it
1924 was sent using silc_server_send_notify_to_channel function.
1925 Affected file silcd/command.c.
1927 * Fixed silc_server_send_notify_kicked to send the kicker's
1928 Client ID also, it was missing. Affected files are
1929 silcd/command.c, silcd/packet_send.[ch].
1931 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1933 * Do not save client history information in SERVER_SIGNOFF.
1934 Fixes the bug in normal server that it does not detect
1935 the client becoming valid after the server becomes back
1936 online. Affected file silcd/server_util.c.
1938 * Added `sock_error' field into the SilcSocketConnection
1939 context. When error occurs during socket operation (read
1940 or write) the error is saved. Added also new function
1941 silc_socket_get_error to return human readable socket error
1942 message. Affected files are lib/silcutil/silcsockconn.[ch],
1943 lib/silcutil/unix/silcunixsockconn.c, and
1944 lib/silcutil/win32/silcwin32sockconn.c.
1946 * The server now prints the socket error message in the
1947 signoff for client. Affected file silcd/server.c.
1949 * Fixed the `created' channel information sending from router
1950 to server in JOIN command. Checks now whether the channel
1951 really was created or not and set it according that.
1953 Fixed the JOIN command to use the client entry's current
1954 ID during the joining procedure instead of the one it sent
1955 in the command (it is checked though), since it can change
1956 between the packet processing and command processing, and
1957 would just case unnecessary pain in the client end. Affected
1958 file silcd/command.c.
1960 * Fixed a channel key payload sending to use correct channel
1961 ID when the server was forced to change the channel's ID by
1962 router. Router sent the key payload with the old Channel ID.
1963 Affected file silcd/packet_receive.c.
1965 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1967 * Call silc_server_save_channel_key only if the key payload
1968 was provided in the JOIN command's command reply. Affected
1969 file silcd/command_reply.c.
1971 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1973 * Fixed silc_mp_sizeinbase to return the value correctly with
1974 MPI. Affected file lib/silcmath/mp_mpi.c.
1976 * Fixed the stop_server signal to correctly stop the scheduler
1977 and gracefully stop the server when SIGTERM or SIGINT signals
1978 are received. Affected file silcd/silcd.c.
1980 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1982 * Simple handling of TERM and HUP signals. Also added some log
1983 flushing call around. Affected file is
1986 * Fixed small bugs in silclog.c. Now buffering output will take
1987 effect after 10 seconds since startup: This will ensure that
1988 no important startup messages are lost. Also output redirection
1989 will preserve original format ([Date] [Type] message).
1990 Affected file is lib/silcutil/silclog.c.
1992 * Added two options to the config file, in the logging section:
1993 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1994 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1996 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1998 * Do not print the warning about log files not being initialized
1999 more than once to avoid excess logging. Affected file is
2000 lib/silcutil/silclog.c.
2002 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
2003 the SIM copying in make install in Makefile.am.pre.
2005 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2007 * Rewritten silclog APIs. Globally interesting changes follows:
2008 silc_log_set_files() changed to silc_log_set_file().
2009 silc_log_set_callbacks() changed to silc_log_set_callback().
2010 ROBOdoc documented silclog header file.
2011 SilcLogCb now returns bool to wether inihibit the default
2012 handler or not (to keep the old behaviour return always TRUE).
2013 The new APIs should also fix the problem of the
2014 silcd_error.log file that was written in the current directory.
2017 Log files streams will remain opened after silc_log_set_file()
2018 call, means less CPU usage notably on high traffic servers.
2019 File streams are now full buffered, and flushed to the disk
2020 every 5 minutes, lesses HD activity and CPU usage.
2021 Messages can be redirected, allowing admins to configure
2022 one single logfile for all server messages.
2023 the silc_log_quick global variable to activate fast-logging.
2024 Affected files lib/silcutil/silclog.[ch]
2026 * Changed some code to conform new silclog APIs. Affected
2027 files are doc/example_silcd.conf.in, silcd/server.c
2028 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
2031 * Fixed a memory leak that could occur in some situations.
2032 Affected file silcd/serverconfig.c.
2034 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2036 * Added the silc_client_del_client to remove the client from
2037 all channels as well. Affected file lib/silcclient/idlist.c.
2039 * Fixed the client library to correctly remove the client
2040 from all channels when the client entry is being destroyed.
2041 Affected file lib/silcclient/client_notify.c, command.c.
2043 * Added auto-nicking support to the client library. If the
2044 applicatio now sets client->nickname it will be sent to the
2045 server after connecting by the library. This way for example
2046 SILCNICK (or IRCNICK) environment variables will have effect
2047 and always change the nickname automatically to whatever
2048 it is wanted. Affected file lib/silcclient/client.[ch].
2050 * Renamed silc_server_command_bad_chars to the
2051 silc_server_name_bad_chars and moved it to the
2052 silcd/server_util.[ch]. Added also new function
2053 silc_server_name_modify_bad to return nickname that
2054 includes bad characters as new nickname without those
2055 bad characters. This check and modify is now used in
2056 silc_server_new_client when the username is initially set
2057 as nickname, so it must be checked to be valid nickname.
2058 Affected file silcd/packet_receive.c.
2060 * The nickname length is now taken from the packet for real
2061 and not trusted to strlen() since it clearly can return
2062 wrong length for nickname including bad characters. This
2063 also applies to channel names. Affected file silcd/command.c.
2065 * Removed the lib/silcsilm/modules directory. Modules are now
2066 compiled into the lib/silcsim. Fixed the copying of the
2067 modules to follow symbolic links in Makefile.am.pre.
2069 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2071 * Fixed silc_string_regexify list creation. Fixes bugs with
2072 BAN and INVITE commands in server. The affected file is
2073 lib/silcutil/unix/silcunixutil.c.
2075 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2077 * Removed the command destructor entirely from the server's
2078 command and command reply routines. It is not needed, and
2079 its usage was buggy and caused crashes. Affected files are
2080 silcd/command[_reply].[ch].
2082 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2084 * Cancel protocol and NULL sock->protocol if timeout
2085 occurred during protocol. Affected file silcd/server.c.
2087 * Cancel protocol timeouts always before calling the final
2088 callback, to assure that after final callback is called
2089 no other state will be called for the protocol anymore.
2090 Affected file silcd/protocol.c.
2092 * Print error log if incoming connection configuration could
2093 not be found. Affected file silcd/server.c.
2095 * Fixed JOIN command to correctly save the founder mode
2096 to the client on normal SILC server, when the channel
2097 was created by the router. Affected file silcd/command.c.
2099 * Fixed LIST command (hopefully) to send correct reply
2100 packets. Affected file silcd/command.c.
2102 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2104 * The silc_packet_receive_process now returns FALSE if the
2105 read data was invalid packet, and TRUE if it was ok.
2107 The server now checks that if unauthenticated connection
2108 sends data and its processing fails the server will close
2109 the connection since it could be a malicious flooder.
2111 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
2113 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2115 * Make sure the warning about error opening a log file is
2116 printed only once and not everytime it fails (produces
2117 too much useless log). Affected file lib/silcutil/silclog.c.
2119 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2121 * Made the silc_server_daemonise() function more readable.
2122 Affected file silcd/server.c.
2124 * Pid file is now optional, the user may comment it out from
2125 the config file. Removed define SILC_SERVER_PID_FILE, we
2126 don't need a default any longer. Affected file
2127 configure.in.pre, lib/Makefile.am.pre.
2129 * Make some use of the pid file. The server now dies at startup
2130 if it detects a valid pid file on his path. The server would
2131 die anyway in this circumstance, because of the bind() failure.
2132 Affected file silcd/silcd.c.
2134 * No longer compiling lib/dotconf.
2136 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2138 * Fixed JOIN command parsing not to crash. Affected file
2139 lib/silcclient/command.c.
2141 * Fied the NICK_CHANGE notify to add the new client entry
2142 even it is resolved. This removes an <[unknown]> nick
2143 thingy bug in the client. Affected file is
2144 lib/silcclient/client_notify.c.
2146 * Do not try to allocate 0 bytes (efence does not like it)
2147 in lib/silccore/silccomand.c when encoding payload.
2149 * Do not take IRCNICK as nickname in Irssi SILC client since
2150 it is not possible to set nickname before hand connecting
2151 the server (TODO has an entry about adding auto-nicking
2154 * Changed the silc_server_command_pending to check whether
2155 there already exists an pending entry with the specified
2156 command, command identifier and pending callback. This is
2157 to fix IDENTIFY and WHOIS related crashes that may register
2158 multiple pending commands with same identifier. Affected
2159 file silcd/command.c.
2161 * Fixed the server to reconnect to the router even if it
2162 was already reconnecting and EOF was received. This to
2163 fix a possibility that the server wouldn't ever try to
2164 auto-reconnect to the router. Affected file silcd/server.c.
2166 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2168 * Fixed the server's password authentication to use the
2169 length of the locally saved password, and not the one
2170 sent in the packet. Affected file silcd/protocol.c.
2172 * Fixed same password authentication problem in the
2173 Authentication Payload handling routines in
2174 lib/silccore/silcauth.c.
2176 * Yet another password authentication problem fixed with
2177 channel password handling in silcd/command.c.
2179 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2181 * If first character of string in silc_parse_userfqdn is '@'
2182 then do not parse it. Affected file is
2183 lib/silcutil/silcutil.c.
2185 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2187 * Fixed minor bug in IDENTIFY command reply sending, which
2188 caused various weird problems during JOIN when it was
2189 resolving names for users. Affected file silcd/command.c.
2191 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2193 * Fixed the IDENTIFY command reply sending to chech better valid
2194 clients. It was possible to send incomplete list of replies.
2195 Affected file silcd/command.c.
2197 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2199 * Added silc_client_command[s]_[un]register functions now to
2200 dynamically register the commands in client library. Removed
2201 the static table of commands. This allows the client library
2202 to call commands without causing the application to know about
2203 what commands library has called.
2205 Removed the INFO command reply kludge to detect when the command
2206 was called by library. Now library use its own command reply
2207 function for INFO command.
2209 Added function silc_client_command_call to call a command.
2210 Application can use it to call command, not access the structure
2213 Now all commands that are sent by the client library (not
2214 explicitly sent by application) use own command reply functions.
2216 Affected files around lib/silcclient/ and in
2217 irssi/src/silc/core/.
2219 * Fixed the WHOIS command reply sending to chech better valid
2220 clients. It was possible to send incomplete list of replies.
2222 Fixed the WHOIS and IDENTIFY to send the request to router
2223 if normal server did not do it and did not find any results.
2225 Affected file silcd/command.c.
2227 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2229 * Moved the internal data from SilcClient context into its
2230 own file, not accesible to application. Affected files
2231 lib/silcclient/client.h and lib/silcclient/client_internal.h,
2232 and other files in client library.
2234 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2236 * Added doc/examples installation target in Makefile.am.pre.
2239 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2241 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
2242 commands the found client entry will be removed from the
2243 cache, after notifying application about the error. Affected
2244 file lib/silcclient/command_reply.c.
2246 * Changed the /MSG to check for exact nickname user gave, and
2247 not let `nick' match `nick@host' if it is only one found. Now,
2248 user must type the exact nickname (like nick@host2) even if
2249 there are no more than one same nicks found. This is to avoid
2250 a possibility of sending nickname to wrong nickname since
2251 `nick' could match `nick@host'. Affected file is
2252 irssi/src/core/silc-servers.c.
2254 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2256 * Do not print "you are now server operator" or similar when
2257 giving /away command. Affected files are
2258 irssi/src/silc/core/client_ops.c, silc-servers.h.
2260 * Made the silc_server_command_pending_error_check to send
2261 the same command reply payload it received back to the
2262 original sender of the command. This way all arguments
2263 that was received by the server will be received by the
2264 client too. Affected file silcd/command.c.
2266 * Added the silc_idcache_add to return the created cache entry
2267 to a pointer. Affected file lib/silccore/silcidcache.[ch].
2269 * Add global clients to expire if they are not on any channel.
2270 This is because normal server will never know if they signoff
2271 if they are not on any channel. The cache expiry will take
2272 case of these entries. This is done by normal servers only.
2273 The affected files are silcd/command_reply.c,
2274 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
2276 * If server receives invalid ID notification for WHOIS or
2277 IDENTIFY and the ID exists in the lists, it is removed.
2278 Affected file silcd/command_reply.c.
2280 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
2281 in client then client entry that it matches is searched and
2282 the nickname is printed on the screen for user. Affected
2283 file irssi/src/silc/core/client_ops.c.
2285 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2287 * Use cache entry expire time in the LIST command reply to
2288 purge old entries from the cache after the LIST command
2289 reply has been received. This way we don't have non-existent
2290 entries in the cache for too long. Affected file is
2291 silcd/command_reply.c.
2293 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2295 * If we are normal server, and we've not resolved client info
2296 in WHOIS or IDENTIFY from router, and it is global client,
2297 we'll check whether it is on some channel. If it is not
2298 then we cannot be sure about its validity and will resolve it
2299 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
2300 file silcd/command.c.
2302 * Search channel by name (if possible) rather than by ID
2303 in IDENTIFY command's command reply. Affected file is
2304 silcd/command_reply.c.
2306 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2308 * Distribute to the channel passphrase in CMODE_CHANGE notify.
2309 Updated specs and implemented it. Affected file silcd/command.c,
2310 silcd/packet_send.c and silcd/packet_receive.c.
2312 * Implemented the <founder auth> payload handling in the JOIN
2313 command. If provided all conditions for channel joining
2314 except requirement to provide correct passphrase can be
2315 overrided by the channel founder. Updated the protocol specs.
2316 Affected file silcd/command.c.
2318 Added support for founder auth in JOIN command in client
2319 library. Fixed the parsing of the JOIN command now to support
2320 all options as they should be. The affected file is
2321 lib/silcclient/command.c.
2323 * Optimized the WHOIS and IDENTIFY commands to send the request
2324 to router only if it includes nicknames or other names. If
2325 they include only IDs then check the local cache first before
2326 routing. Affected file is silcd/command.c.
2328 * Added channels topic announcements. Affected file is
2329 silcd/packet_receive.c and silcd/server.c.
2331 * Fixed the silc_server_send_notify_topic_set to really destine
2332 the packet to channel. Affected file silcd/packet_send.c.
2334 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
2335 library. Affected file lib/silcclient/client_notify.c.
2337 * Added UMODE announcements. Affected file silcd/server.c.
2339 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2341 * Memory leak fixes in:
2343 lib/silcutil/silcsockconn.c
2344 lib/silcske/silcske.c
2345 lib/silcske/groups.c
2347 lib/silccrypt/silcpkcs.c
2348 lib/silccore/silccommand.c
2349 lib/silccore/silcidcache.c
2354 * ROBOdoc documented the lib/silcske/groups.h file and a
2355 bit changed the interface for better.
2357 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2359 * Update the client entry context in the ID cache after
2360 nick change. Affected file lib/silcclient/command.c.
2361 Fixes the CUMODE command when regaining founder privileges,
2362 and a little WHOIS problem.
2364 * Fixed silc_net_gethostbyname to correctly call the
2365 inet_ntop. Affected file lib/silcutil/silcnet.c.
2367 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2369 * Added IPv6 support checking to the configure.in.pre, added
2370 also --enable-ipv6 option to override the check. Affected
2371 file configure.in.pre.
2373 * The silc_thread_create now calls the start function
2374 directly if threads support is not compiled in. Removes
2375 ugly #ifdef's from generic code. Affected files are
2376 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
2378 * Added silc_net_gethostby[name/addr]_async to asynchronously
2379 resolve. Affected files are lib/silcutil/silcnet.[ch].
2381 * Added support for rendering IPv6 based server, client and
2382 channel IDs. Affected file lib/silcutil/silcutil.c.
2384 * Added support for creating IPv6 based server IDs. Affected
2385 file is silcd/serverid.c.
2387 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2389 * Added silc_net_gethostby[addr/name] into the
2390 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
2391 routines. Added silc_net_is_ip[4/6]. Affected file is
2392 lib/silcutil/unix/silcunixnet.c. All routines that take
2393 address as argument now supports both IPv4 and IPv6 addresses.
2395 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2397 * Fixed LIST command reply sending in server. Affected file
2400 * Server now sends the kicker's client ID in the KICK notify
2401 to the kicked client. Affected file silcd/command.c.
2403 * The client library now parses the kickers client ID and
2404 UI displays it. Affected files lib/silcclient/client_notify.c
2405 and irssi/src/silc/core/silc-channels.c, module-formats.c.
2407 * Made all payload parsing function prototypes consistent.
2408 They all take now const unsigned char * and uint32 pair as
2409 the payload data instead of SilcBuffer. Changes all around
2410 the source tree. Other unsigned char* -> const unsigned char*
2411 changes around the tree as well.
2413 * Optimized SFTP client and server packet sending not to
2414 allocate new buffer for each packet but to recycle the
2415 first allocated buffer. Affected files are
2416 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
2418 * Optimized the SFTP client to use SilcList instead of
2419 SilcDList for requests, because it is faster. Affected file
2420 is lib/silcsftp/sftp_client.c.
2422 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
2423 into lib/silccore/silcid.[ch].
2425 Renamed silcpayload.[ch] into silcargument.[ch].
2427 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2429 * If client entry is deleted with active key agreement
2430 session, abort the session.
2432 The silc_client_abort_key_agreement now calls the completion
2433 callback with new SILC_KEY_AGREEMENT_ABORTED status.
2435 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
2438 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2440 * Don't use __restrict in older GCC's. Affected file is
2441 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
2443 * silc_net_localhost now attempts to reverse lookup the
2444 IP/hostname. Affected file lib/silcutil/silcnet.c.
2446 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
2447 command. It can be used to gain founder privileges at
2448 the same time when joining the channel.
2450 Defined that the SILC_NOTIFY_TYPE_KICKED send the
2451 kicker's client ID as well. Updated protocol specs.
2453 Defined that the server must send SILC_COMMAND_IDENTIFY
2454 command reply with error status to client who sent
2455 private message with invalid client ID.
2457 Updated the protocol specification.
2459 * Added silc_server_send_command_reply to send any
2460 command reply. Affected file silcd/packet_send.[ch].
2462 * Added silc_id_payload_encode_data to encode ID payload
2463 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
2465 * The server now send IDENTIFY command reply with error
2466 status if client ID in private message is invalid. Affected
2467 file silcd/packet_receive.c.
2469 * Save the server key file with server's IP address in
2470 the filename instead of hostname. The affected file is
2471 irssi/src/silc/core/client_ops.c.
2473 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2475 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
2478 * Added libtool support for compiling shared objects in
2479 lib/silcsim. Affected file configure.in.pre and
2480 lib/silcsim/Makefile.am. Original patch by cras.
2482 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2484 * Pid file configuration, and server's config file fixes
2485 patch by toma. Updated CREDITS file.
2487 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2489 * Fixed silc_client_channel_message to not try to decrypt
2490 the message twice if it resolved the destination client
2491 information. This could cause of dropping one channel
2492 message. Affected file lib/silcclient/client_channel.c.
2494 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2496 * Added silc_client_run_one into lib/silcclient/silcapi.h and
2497 lib/silcclient/client.c. This function is used when the SILC
2498 Client is run under some other scheduler, or event loop or
2499 main loop. On GUI applications, for example this may be
2500 desired to used to run the client under the GUI application's
2501 main loop. Typically the GUI application would register an
2502 idle task that calls this function multiple times in a second
2503 to quickly process the SILC specific data.
2505 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2507 * Fixed silc_server_drop() for dropping the supplementary
2508 groups as well, this could cause a security hole on some
2511 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2513 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
2516 * Write PID file after dropping privileges. Added -F option
2517 to run server on foreground. A patch by debolaz.
2518 Affected files silcd/server.c, silcd/silcd.c.
2520 * Fixed MOTD to return the MOTD file server name. Affected
2521 file silcd/command.c.
2523 * Added INFO command reply handling to the Irssi SILC Client.
2524 Affected file irssi/src/silc/core/client_ops.c.
2526 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2528 * Fixed the silc_idcache_list_* routines to really support
2529 the dynamic list. Fixes a crash. Affected file is
2530 lib/silccore/silcidcache.c.
2532 * Fixed the LIST command reply to really call LIST command's
2533 pending callbacks. Affected file silcd/command_reply.c.
2535 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2537 * Update conn->local_entry->nickname after giving NICK
2538 command. Affected file lib/silcclient/command.c.
2540 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
2542 * Added the [pid] option to the silcd configuration file
2544 Affected files: serverconfig.[ch] and silcd.c
2546 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2548 * Save fingerprint in WHOIS command reply in server.
2549 Affected file silcd/command_reply.c.
2551 * Fixed NICK commands pending callback registration.
2552 Affected file lib/silcclient/command.c.
2554 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2556 * Use ++server->cmd_ident when sending commands in server,
2557 instead of random number. Affected file silcd/command.c.
2559 * Fixed GETKEY command reply to call actually GETKEY pending
2560 command callbacks. Affected file silcd/command_reply.c.
2562 * A bit stricter check for nicknames. Check for same nickname
2563 in NICK command also. Affected file silcd/command.c.
2565 * Do not call INFO command everytime client ID changes, only
2566 during first connecting. Affected file lib/silcclient/client.c.
2568 * Set the new nickname only after successful command reply for
2569 NICK command is returned by server. Affected file
2570 lib/silcclient/command.c.
2572 * Remove nicknames from nicklist during server_signoff notify.
2573 Should fix /NAMES bit more. The affected file is
2574 irssi/src/silc/core/silc-channels.c.
2576 * Added `fingerprint' field to the SilcIDListData in the
2577 silcd/idlist.h to hold the fingerprint of the client's
2580 Send the fingerprint of the client's public key in WHOIS
2583 Affected files silcd/command.c, and silcd/idlist.[ch].
2585 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
2586 create fingerprint from given data.
2588 * Show the fingerprint of the client's public key in WHOIS.
2589 Affected files irssi/src/module-formats.[ch] and
2590 irssi/src/silc/core/client_ops.c.
2592 * Format the multiple same nicknames also during JOIN and
2593 NICK_CHANGE notifys. Affected file is
2594 lib/silcclient/client_notify.c.
2596 * Do not print error on screen for invalid private message
2597 payload since it can come if someone is sending private
2598 messages with wrong key. Affected file
2599 lib/silccore/silcprivate.c.
2601 * Fixed multiple concurrent /PING crash. Affected file
2602 lib/silcclient/command.c.
2604 * Changed the wrong ID encoding. All IP addresses must be
2605 in MSB first order in encoded format. They were encoded
2606 wrong and was in LSB format. Affected files are
2607 silcd/serverid.c, lib/silcutil/silcutil.c.
2609 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
2611 * Call the `connect' client operation through the scheduler
2612 in case of error. Affected file lib/silcclient/client.c.
2614 * Call the `failure' client operation even if the error
2615 occurred locally during a protocol. Affected file is
2616 lib/silcclient/protocol.c.
2618 * Added support of sending LIST command to router from normal
2619 server. This way normal server can get list of all channels
2620 in the network too. Fixed the channel list sending in the
2621 server too. Affected files are silcd/command.c, and
2622 silcd/command_reply.[ch].
2624 * Added silc_server_update_channels_by_server and
2625 silc_server_remove_channels_by_server. They are used during
2626 disconnection of primary router and in backup router protocol.
2627 Affected file silcd/server_util.[ch], silcd/server.c and
2628 silcd/server_backup.c.
2630 * Fixed channel adding to global list in IDENTIFY command
2631 reply in server. Affected file silcd/command_reply.c.
2633 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2635 * If the incoming packet type is REKEY or REKEY_DONE process
2636 that packet always synchronously. Fixes yet another MAC
2637 failed error on slow (dialup) connections. Affected file
2638 lib/silcclient/client.c and silcd/server.c.
2640 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2642 * Call check_version SKE callback for initiator too. Affected
2643 file lib/silcske/silcske.c.
2645 * Implemented fix for security hole found in the SKE that was
2646 fixed in the specification few days back; the initiator's
2647 public key is now added to the HASH value computation.
2648 Added backwards support for the old way of doing it too, for
2649 old clients and old servers. Affected file is
2650 lib/silcske/silcske.c.
2652 * Enabled mutual authentication by default in SKE. If initiator
2653 is not providing mutual authentication the responder will
2654 force it. This will provide the proof of posession of the
2655 private key for responder. The affected files are
2656 lib/silcclient/protocol.c and silcd/protocol.c.
2658 * Do not cache anymore the server's public key during SKE.
2659 We do mutual authentication so the proof of posession of
2660 private key is done, and if the server is authenticated in
2661 conn auth protocol with public key we must have the public
2662 key already. Affected file silcd/protocol.c.
2664 * Added new global debug variable: silc_debug_hexdump. If
2665 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
2666 file lib/silcutil/silclog.[ch].
2668 * Fixed compilation warning due to char * -> const char *.
2669 Affected files lib/silcutil/silcnet.h, and
2670 lib/silccore/silcauth.[ch].
2672 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2674 * Fixed CMODE command when new channel key was created. If
2675 the creation failed the old key was removed. Next time giving
2676 same command would crash the server since the old key was
2677 freed already. Affected file silcd/command.c.
2679 * Fixed the silc_server_announce_get_channels to not crash
2680 on reconnect. Affected file silcd/server.c.
2682 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2684 * Added silc_log_set_debug_string function to set a regex
2685 string to match for debug output. Only the function names,
2686 or filenames matching the given debug string is actually
2687 printed. This way it is possible to filter out those debug
2688 strings that user is not interested in.
2690 Fixed a bug in silc_string_regexify.
2692 Affected files lib/silcutil/silclog.[ch], and
2693 lib/silcutil/unix/silcunixutil.c.
2695 * Changed the -d options in both server and Irssi SILC client
2696 to take the debug string as argument. Affected files
2697 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
2699 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2701 * Added silc_hash_babbleprint to create a Bubble Babble
2702 Encoded fingerprint. The encoding is developed by Antti
2703 Huima (draft-huima-babble-01.txt), and it creates human
2704 readable strings out of binary data. Affected file
2705 lib/silccrypt/silchash.[ch].
2707 * Print the babble print now in addition of fingerprint as well
2708 in Irssi SILC client. Affected files are
2709 irssi/src/fe-common/silc/module-formats.[ch],
2710 irssi/src/fe-common/silc/core/client_ops.c.
2712 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2714 * Fixed a security problem found in SKE. The initiator's
2715 public key too is now added to the HASH hash value creation
2716 which is signed by the responder to create the SIGN value.
2717 This will prevent anyone in the middle to lie to the responder
2718 about the initiator's public key. If this is done now, the
2719 man in the middle will get caught. Updated the protocol
2722 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2724 * Better installation directory handling. Configure module
2725 paths and other paths automatically to example_silc* files
2726 in doc/. A patch by toma.
2728 * Fixed compiler warning from MPI library, and from SILC RNG.
2731 * Added SILC_SERVER_PID_FILE to define the pid file for server.
2732 It can be configured with ./configure. A patch by toma.
2734 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2736 * Find correct make to use in prepare-clean. A patch by
2737 toma. Affected file prepare-clean.
2739 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
2741 * Added irssi variables use_auto_addr, auto_bind_ip,
2742 auto_bind_port and auto_public_ip.
2744 * Changed the interface for silc_client_send_key_agreement
2745 in lib/silcclient/silcapi.h
2749 irssi/src/silc/core/silc-core.c
2751 lib/silcclient/silcapi.h
2752 irssi/src/silc/core/silc-channels.c
2753 lib/silcclient/client_keyagr.c
2756 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2758 * Added silc_pkcs_public_key_compare to compare two
2759 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
2761 * Check that the client who set the founder mode on the
2762 channel is the same client that is giving the founder
2763 mode to itself. It is done by comparing the saved public
2764 key (it is saved even in the authentication is passphrase).
2765 Affected file silcd/command.c.
2767 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2769 * Do not process packet for disconnected socket connection.
2770 Affected file lib/silccore/silcpacket.c.
2772 * Process the DISCONNECT packet through scheduler in the
2773 client library. Affected file lib/silcclient/client.c.
2775 * Fixed the silc_client_packet_parse to not to increase
2776 the packet sequence number if the conn->sock and the
2777 current socket connection is not same. This can happen
2778 for example during key agreement when the conn includes
2779 multiple socket connections (listeners). Affected file
2780 lib/silcclient/client.c.
2782 * The sender of the file transfer request now provides also
2783 the pointer (listener) for the key exchange protocol. If
2784 the listener cannot be created then it sends empty key
2785 agreement and lets the receiver provide the listener.
2787 Added `local_ip' and `local_port' arguments to the
2788 silc_client_file_send. If they are provided they are used,
2789 if not then it will attempt to find local IP address, if
2790 not found or bind fails then the remote client will provide
2793 Affected files are lib/silcclient/client_ftp.c and
2794 lib/silcclient/silcapi.h.
2796 * Extended the FILE SEND command to support defining the
2797 local IP and port for key exchange listener. They are
2798 optional. Affected file irssi/src/silc/core/silc-servers.c.
2800 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2802 * Defined to WHOIS command reply the sending of fingerprint
2803 of the client's public key (if the proof of posession of the
2804 corresponding private key is verified by the server).
2805 Updated to the protocol specification.
2807 * Added support of receiving the client's public key's
2808 fingerprint in command reply in client library. Affected
2809 file is lib/silcclient/command_reply.c, and
2810 lib/silcclient/idlist.[ch].
2812 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2814 * Do not send over 128 chars long nickname to the server
2815 in NICK command. Affected file lib/silcclient/command.c.
2817 * Do not send over 256 chars long channel names to the server
2818 in JOIN command. Affected file lib/silcclient/command.c.
2820 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2822 * Assure that silc_server_close_connection cannot be called
2823 twice for same socket context. Affected file is
2826 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2828 * Send error message to application if opening file for
2829 writing during file transfer fails. Affected file is
2830 lib/silcclient/client_ftp.c.
2832 Remove all file transfer sessions for a client that we're
2833 removing from ID cache.
2835 Affected file is lib/silcclient/client_ftp.c.
2837 * Fixed silc_net_addr2bin to return correct address. Affected
2838 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2840 * Fixed file transfer session removing on signoff notify.
2841 Affected file irssi/src/silc/core/silc-servers.c.
2843 * Added the SilcClientFileError to be returned in the monitor
2844 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
2845 Affected file lib/silcclient/silcapi.h.
2847 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2849 * Fixed a crash in silc_client_ftp_free_sessions and
2850 silc_client_ftp_session_free_client. Affected file
2851 lib/silcclient/client_ftp.c.
2853 * Added `disabled' field in the SilcChannelEntry in the server
2854 to indicate if the server entry is disabled. Affected file
2855 silcd/idlist.h, silcd/command[_reply].c.
2857 * SILC server adds now /var/run/silcd.pid everytime it is
2858 started. Affected file silcd/silcd.c.
2860 * Added silc_server_packet_send_clients to send a packet to
2861 the provided table of client entries. Affected file
2862 silcd/packet_send.[ch].
2864 * Fixed a crash in client resolving in client_prvmsg.c in
2865 client library. Affected file lib/silcclient/client_prvmsg.c.
2867 * Do not actually remove the client directly from ID cache
2868 during SERVER_SIGNOFF, but invalidate it. This way we
2869 preserve the WHOWAS info for the client. Affected file
2870 silcd/server_util.c.
2872 * Fixed SERVER_SIGNOFF notify handling in the server. The
2873 server is now able to process incoming SERVER_SIGNOFF notify
2874 for a server that it doesn't even know about. It will remove
2875 the clients provided in the notify. Affected file
2876 silcd/packet_receive.c.
2878 * Check for partial packet in data queue after every packet that
2879 was found from the queue. Return and wait for more data if
2880 there is partial data in queue. Affected file is
2881 lib/silccore/silcpacket.c.
2883 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2885 * Added SilcClietFileError enum to indicate error in
2886 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
2887 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
2888 Affected files lib/silcclient/silcapi.h and
2889 lib/silcclient/client_ftp.c.
2891 * Check that newsize in silc_buffer_realloc is larger than
2892 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
2894 * Added better monitor of file transfers. It now monitors
2895 key agreement protocol during the file transfer too. Added
2896 error reporting too. Affected files
2897 irssi/src/silc/core/silc-servers.c,
2898 irssi/src/fe-common/silc/module-formats.[ch].
2900 * Wrote a help file for FILE command.
2902 * Added silc_rng_global_get_byte_fast to get not-so-secure
2903 random data as fast as possible. Random data is read from
2904 /dev/urandom if available and from the SILC RNG if not
2905 available. It is used in padding generation. Affected file
2906 lib/silccrypt/silcrng.[ch].
2908 * All packets in client library are now processed synchronously.
2909 Optimized packet processing a lot. Affected file
2910 lib/silcclient/client.c.
2912 * All server connection packets are processing synchronously
2913 now in server, to optimize packet processing. Affected file
2916 * Include files are installed now only in Toolkit distribution
2917 if make install is given. Affected files: all Makefile.am's.
2919 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2921 * Assure that silc_client_notify_by_server_resolve does not
2922 resolve the client information multiple times. If it cannot
2923 be found by the first it cannot be found at all. Affected
2924 file lib/silcclient/client_notify.c.
2926 * Fixed WHOWAS command reply calling. Affected file
2927 lib/silcclient/command_reply.c.
2929 * Removed all references to silc_idlist_get_client from the
2930 Irssi SILC client since that call is internal call used by
2931 the library. The Irssi SILC client will use now client
2932 retrieval functions found in silcapi.h.
2934 * Fixed a bug in resolving nickname info before sending
2935 private message. It used freed memory. Affected file
2936 irssi/src/silc/core/silc-servers.c.
2938 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2940 * Assure my_channels statistics cannot go negative in server.
2941 Affected files silcd/server.c, silcd/server_util.c.
2943 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2945 * Upgraded dotconf 1.0.2 to 1.0.6 in lib/dotconf.
2947 Tue Oct 23 13:51:19 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2949 * Win32 Toolkit changes. Affected files
2950 win32/silc.dsw, win32/libsilc/libsilc.def,
2951 win32/libsilcclient/libsilc.def,
2952 lib/silcutil/silcutil.c, and
2953 lib/sftp/sftp_fs_memory.c.
2955 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2957 * Added silc_net_localip to return local host's IP address.
2958 Affected file lib/silcutil/silcnet.[ch].
2960 * If key exchange or rekey protocol is active for a connection
2961 parse all packets syncronously since there might be packets
2962 in packet queue that we are not able to process without first
2963 processing packets before them. Affected file silcd/server,
2964 lib/silcclient/client.c.
2966 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2967 whether library should continue processing the packet.
2968 Affected file lib/silccore/silcpacket.h.
2970 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
2971 SilcSFTPMonitorData to SFTP server to monitor various
2972 SFTP client requests. Affected file lib/silcsftp/silcsftp.h,
2973 lib/silcsftp/sftp_server.c.
2975 * Added silc_file_size to return file size. Affected file
2976 lib/silcutil/silcutil.[ch].
2978 * Implemented the file transfer support for the client library.
2979 Added preliminary support for simple client to client one-file
2980 transmission. Affected file lib/silcclient/client_ftp.c,
2981 lib/silccilent/client.[ch].
2983 * Added new local command FILE to the Irssi SILC Client.
2984 It is used to perform the file transfer. It has subcommands
2985 SEND, RECEIVE, SHOW and CLOSE. Affected files
2986 irssi/src/silc/core/client_ops.c,
2987 irssi/src/silc/core/silc-server.[ch].
2989 Mon Oct 22 12:50:08 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2991 * Relay the SILC_PACKET_FTP in the server. Affected files
2992 silcd/server.c and silcd/packet_receive.c.
2994 Sun Oct 21 20:21:02 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2996 * Renamed silc_file_read and silc_file_write to functions
2997 silc_file_readfile and silc_file_writefile. Added function
2998 silc_file_open and silc_file_close. Affected files
2999 lib/silcutil/silcutil.[ch].
3001 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3003 * Resolve the client info when received private message or
3004 channel message for a client which nickname we don't know.
3005 Affected files lib/silcclient/client_prvmsg.c and
3006 lib/silcclient/client_channel.c.
3008 * Do not crash in /KEY if client is not connected. Affected
3009 file irssi/src/silc/core/silc-channels.c.
3011 * Added SilcClientStatus field to the SilcClientEntry in the
3012 lib/silcclient/idlist.h.
3014 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
3015 is incomplete and is being resolved, it won't be resolved
3018 Make sure also that USERS command reply does not resolve
3019 twice information. Affected file is
3020 lib/silcclient/command_reply.c.
3022 Make sure that silc_client_get_clients_by_list does not
3023 resolve twice same information.
3025 * Check for valid client->id in the silc_server_free_client_data.
3026 Affected file silcd/server.c.
3028 * Fixed /GETKEY nick@server not to crash if the server entry
3029 is not found. Affected file lib/silcclient/command.c.
3031 * Fixed the silc_server_check_cmode_rights to check the
3032 requested modes correctly. Affected file silcd/command.c.
3034 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3036 * Better checks for non-printable chars in nick added.
3037 Affected file silcd/command.c.
3039 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3041 * Call the silc_server_udpate_servers_by_server in the
3042 primary router that comes back online in the backup resuming
3043 protocol. Otherwise it routes packets wrong. Affected file
3044 silcd/server_util.[ch], silcd/server_backup.c.
3046 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3048 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
3049 lib/silcutil/silcbuffmt.[ch].
3051 * Redefined the SILC packet header to include the padding
3052 length. Affected file lib/silccore/silcpacket.[ch].
3054 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
3055 length for maximum padding up to 128 bytes). Affected
3056 file lib/silccore/silcpacket.h.
3058 * Removed all backwards support for old 0.5.x MAC thingies.
3059 The SILC packet header change makes it impossible to be
3060 backwards compatible.
3062 * Send the ENDING packet with timeout in the backup resuming
3063 protocol. This is to assure that all routers has connected
3064 to the primary router. Affected file silcd/server_backup.c.
3066 * Changed the RNG to take the first IV from random data. It
3067 used to take it from zero actually. Changed the RNG also
3068 to use /dev/urandom during session. /dev/random is used
3069 in initialization. Affected file lib/silccrypt/silcrng.[ch].
3071 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3073 * Changed the SILC packet header to have the first two bytes
3074 (the packet length) encrypted. Affected files aroung the
3075 code tree, lib/silccore/silcpacket.[ch]. Removed the
3076 SilcPacketCheckDecrypt callback. It is not needed anymore
3077 since the silc_packet_receive_process will determine now
3078 whether the packet is normal or special.
3080 * Implemented the unidirectional MAC keys. Affected files
3081 lib/silcske/silcske.c, silcd/protocol.c and
3082 lib/silcclient/protocol.c.
3084 * Implemented the packet sequence number to the MAC computation.
3085 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
3086 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
3087 lib/silcclient/protocol.c.
3089 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3091 * Allow backup router to announce servers. All servers
3092 announced by backup router are added to the global list
3093 automatically. Update hte server's socket to our primary
3094 router also when backup router announces a server.
3095 Affected file silcd/packet_receive.c.
3097 * Do not update the client->router in the function
3098 silc_server_udpate_clients_by_server if the client is on
3099 global list. We might fail to find any specific server
3100 for locally connected clients and local cell clients. They
3101 should still use the `from' and not `to' as client->router.
3102 This fixes backup router resuming protocol. Affected file
3103 silcd/server_util.c.
3105 * Decrease channel statistics count only if the channel
3106 deletion worked. Affected files are silcd/server.c and
3107 silcd/server_util.c.
3109 * Added silc_server_update_servers_by_server to update origin
3110 of all server entries. Used during backup router protocol.
3111 Affected files silcd/server_util.[ch], silcd/server.c. and
3112 silcd/backup_router.c.
3114 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
3115 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
3116 silc_hmac_get_hash and silc_hmac_get_name. Affected file
3117 lib/silccrypt/silchmac.c.
3119 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3121 * Assure that router cannot reroute the same channel message
3122 to the sender. Affected file silcd/packet_receive.c.
3124 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3126 * Made better checks that the channel message is not sent
3127 to the router it came from. Affected file is
3128 silcd/packet_send.c. Fixed memory leak too.
3130 * Announce informations for incoming router connection, but
3131 only after checking if it is replaced by backup router.
3132 Affected file silcd/packet_receive.c.
3134 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3136 * Fixed the backup resuming protocol to work in multiple
3137 router environment. Affected file silcd/server_backup.c.
3139 * Route packet only to one router in the function
3140 silc_server_packet_send_to_channel. Affected file is
3141 silcd/packet_send.c.
3143 * Fixed silc_server_send_notify_dest to set the broadcast
3144 flag. Fixed the silc_server_send_notify_topic to actually
3145 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
3146 Affected file silcd/packet_send.c.
3148 * Changed the SFTP Filesystem interface. Changed the
3149 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
3150 the filesystem operation function. The SilcSFTPFilesystem
3151 is now a context that is allocated by all filesystem allocation
3152 functions and it already includes the operations structure
3153 and filesystem specific context. It is given as argument
3154 now to the silc_sftp_server_start. This made the interface
3155 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
3156 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
3158 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3160 * Changed the backup router adding and getting interfaces
3161 in the server. The router that will be replaced by the
3162 specified backup router is now sent as argument. Affected
3163 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
3166 * Added silc_net_addr2bin_ne to return the binary form of
3167 the IP address in network byte order. Affected files
3168 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
3170 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3172 * Check for existing server ID in silc_server_new_server
3173 and in silc_server_connect_to_router_final and remove the
3174 old entry if it exists. Affected file silcd/packet_receive.c,
3177 * Send the channel message always to only one router, either
3178 in upstream or downstream. Affected file is
3179 silcd/packet_send.c.
3181 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3183 * Wrote the definition of the backup resuming protocol to the
3184 protocol specification.
3186 * Removed one redundant channel key generation from normal
3187 server during joining procedure. Removed one redundant
3188 channel key sending from server to router during joining
3189 procedure. Affected file silcd/command.c.
3191 * Made minor bugfixes to the backup router resuming protocol.
3192 Affected file silcd/server_backup.c, server.c.
3194 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3196 * Added --disable-asm configuration option. Affected files
3197 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
3200 * Implemented the backup resuming protocol that is used to
3201 resume the primary router position in the cell after the
3202 primary router comes back online. Affected files
3203 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
3204 and silcd/server_util.[ch].
3206 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3208 * Sleep two (2) seconds after sending QUIT command to server.
3209 Affected file lib/silcclient/command.c.
3211 * Assure that if outgoing data buffer is pending do not force
3212 send any data. Affected file silcd/packet_send.c.
3214 * Assure that if outgoing data buffer is pending do not force
3215 send any data. Affected file lib/silcclient/client.c.
3217 * Implemented the backup router support when the primary router
3218 goes down. The servers and routers can now use the backup
3219 router as new primary router without loosing connectivity.
3221 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3223 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
3224 in the server to indicate disabled entry. All data read
3225 from the connection will be ignored and no data is sent
3226 for entry that is disabled. Affected files are
3227 silcd/idlist.h, silcd/server.c.
3229 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3231 * Created SFTP client and server test programs in the
3232 lib/silcsftp/tests directory.
3234 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3236 * Implemented memory filesystem (virtual filesystem) for
3237 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
3240 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3242 * Implemented the SFTP (SSH File Transfer Protocol) to the
3243 lib/silcsftp. It includes SFTP client and SFTP server
3246 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3248 * Moved lib/silccore/silcprotocol.[ch] to the
3249 lib/silcutil library.
3251 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
3252 take variable argument list pointer as argument. Affected
3253 file lib/silcutil/silcbuffmt.[ch].
3255 * Added silc_buffer_set function that is used to set data
3256 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
3257 Affected file lib/silcutil/silcbuffer.h.
3259 * Changed various routines in the core library to use the new
3260 silc_buffer_set instead of allocating new buffer only for
3263 * Added 64-bit value formatting and unformatting support to the
3264 silc_buffer_[un]format routines. Affected file is
3265 lib/silcutil/silcbuffmt.[ch].
3267 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
3268 to includes/bitmove.h.
3270 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3272 * Fixed channel user mode saving in client library. Affected
3273 file lib/silcclient/command[_reply].c.
3275 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3277 * Defined the file transfer to the SILC Protocol. Added
3278 new packet type SILC_PACKET_FTP and defined File Transfer
3279 Payload. The mandatory file transfer protocol is SFTP
3280 (SSH File Transfer Protocol). Affected file in addition
3281 of the internet draft is lib/silccore/silcpacket.h.
3283 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
3284 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
3285 is used as part of backup router protocol when the primary
3286 router of the cell is back online and wishes to resume
3287 the position as primary router.
3289 * Redefined the MAC generation keys in the protocol. The
3290 same key is not used anymore in both direction. Both
3291 direction will now use different keys for sending and
3292 receiving. This fixes a potential security flaw. This
3293 change causes incompatibilities in the protocol.
3295 * Redefined also the MAC computation from the packet.
3296 An packet sequence number is now added to the MAC
3297 computation. This prevents possible replay attacks against
3298 the protocol. This change too causes incompatibilities
3301 Added `sequence' field to the SilcPacketContext to hold
3302 the current sequence number for the packet.
3304 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3306 * Added `created' field to the SilcIDListData in the file
3307 silcd/idlist.h to indicate the time when the entry was
3310 * Added `created' field to the SilcChannelEntry too. Affected
3311 file silcd/idlist.h.
3313 * Added `creation_time' aguments to all the announcement functions
3314 in the server. If it is provided then only the entries that
3315 was created after the provided time frame are actually
3316 announced. Affected file silcd/server.[ch].
3318 * The protocol says that the Channel ID's IP address must be
3319 based on the router's IP address. Added check for this in
3320 the silc_server_new_channel when processing incoming New Channel
3321 Payload. Affected file silcd/packet_receive.c.
3323 * Print out the correct version with --version in SILC client.
3324 Affected file irssi/src/silc/core/silc-core.c.
3326 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3328 * Fixed WHOWAS command to check for completnes of the client
3329 entry always, not just when the command is coming from client.
3330 Affected file silcd/command.c.
3332 * Added new function silc_server_packet_queue_purge to purge the
3333 outgoing data queue to the network. After the function returns
3334 it is guaranteed that the outgoing packet queue is empty.
3335 Affected file silcd/packet_send.[ch].
3337 * Purge the outgoing packet queue in the rekey protocol's final
3338 callback to assure that all rekey packets go to the network
3339 before quitting the protocol. Affected file silcd/server.c.
3341 * Added silc_client_packet_queue_parse as similar function as
3342 in server to the client library. The affected file is
3343 lib/silcclient/client.c.
3345 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3347 * Splitted silcd/server.c and created silcd/server_util.[ch]
3348 for utility functions.
3350 * Added new socket flag SILC_SF_DISABLED to indicate that the
3351 connection is open but nothing can be sent to or received from
3352 the connection. Affected file lib/silcutil/silsockconn.[ch].
3353 The checking for disabled socket is checked in the low level
3354 silc_socket_write and silc_socket_read functions.
3356 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3358 * Allow only nicknames and channel names that fits into the
3359 7-bit unsigned char ASCII set. Affected file silcd/command.c.
3361 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3363 * When processing JOIN command reply in server check that if
3364 the channel exists in our global list we'll move it the local
3365 list. Affected file silcd/command_reply.c.
3367 * Fixed the check whether client is joined on the channel already
3368 in JOIN command. Affected file lib/silcclient/command.c.
3370 * Fixed the JOIN command reply to check whether the channel
3371 already exists. Affected file lib/silcclient/command_reply.c.
3373 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3375 * Added silc_ske_status_string to map the SKE error numbers
3376 to readable strings. The affected files are
3377 lib/silcske/silcske[_status].[ch].
3379 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3381 * Do not show the private channels on the WHOIS channel list
3382 as it is not allowed by the protocol. The affected file is
3385 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3387 * Assure that the packet length digged from the actual packet
3388 is something sensible in the silc_packet_decrypt_rest_special
3389 in lib/silccrypt/silcpacket.c.
3391 * Free and NULL the allocated pointer in silc_hmac_alloc if
3392 the HMAC allocation fails. The affected file is
3393 lib/silccrypt/silchmac.c.
3395 * Print the selected security properties to the log files in
3396 the server. Affected file silcd/protocol.c.
3398 * Add SKE's reference counter even if calling the completion
3399 callback manually. Otherwise it goes negative, although it
3400 does not cause any problems. The affected file is
3401 lib/silcske/silcske.c.
3403 * Remove the client entry with short timeout after giving the
3404 KILL command. Affected file lib/silcclient/command.c.
3406 * Fixed to send error reply in WHOIS and IDENTIFY commands in
3407 case all found clients are already disconnected (WHOWAS would
3408 found them) in the server. Affected file silcd/command.c.
3410 * Update the last_receive (time of last data received) to be
3411 updated only when received private or channel message so that
3412 the idle time showed in WHOIS makes more sense.
3414 * Added boolean field `valid' in to the SilcClientEntry in the
3415 client library to indicate whether the entry is valid or not.
3416 This fixes the nickname change bug on channel when changing
3417 the nickname to be same than the old (like nick to Nick) the
3418 nickname formatter doesn't set the new nick anymore to Nick@host.
3419 Affected file lib/silcclient/idlist.[ch].
3421 * Now actually fixed the nickname changing on disconnection.
3422 Added new function silc_change_nick to the Irssi SILC Client.
3423 Affected file irssi/src/silc/core/client_ops.c,
3424 irssi/src/silc/core/silc-nicklist.[ch].
3426 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3428 * Check that the public key exists in the GETKEY command before
3429 trying to encode it. Affected file silcd/command.c.
3431 * Print some notifications on received public keys with GETKEY
3432 command in the Irssi SILC Client. Affected files are
3433 irssi/src/fe-common/silc/module-formats.[ch],
3434 irssi/src/silc/core/client_ops.c.
3436 * Use IDENTIFY command to resolve the server information in the
3437 GETKEY command instead of INFO command. Affected file
3438 lib/silcclient/command.c.
3440 * All command reply functions in the client library now calls
3441 the pending command reply callbacks even if an error has
3442 occurred. The server has done this a long time and now it was
3443 time to move the client library to this as well. Now all
3444 errors can be delivered back to the pending command reply
3445 callbacks if necessary. Affected files are
3446 lib/silcclient/command[_reply].[ch].
3448 * Change the nickname on disconnection back to the username
3449 because in reconnect the server will enforce it to it anyway.
3450 Affected file irssi/src/silc/core/silc-servers.c.
3452 * Fixed a config file parsing bug in the Irssi SILC client.
3453 Affected file irssi/src/silc/core/clientconfig.c.
3455 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3457 * When printing the channel mode on JOIN, verify that the
3458 channel key and channel's HMAC are valid. Affected file
3459 irssi/src/silc/core/client_ops.c.
3461 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3463 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
3464 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
3465 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
3467 * Removed channel key rekey task deleting from the function
3468 silc_server_save_channel_key. Affected file silcd/server.c.
3469 Added explicit timeout task context instead that is used to
3470 delete the task if we are registering a new task before the
3471 new task has elapsed.
3473 * When channel key rekey occurs the client library now saves
3474 the old channel key for a short period of time (10 seconds) and
3475 is able to use it in case some is still sending channel
3476 messages encrypted with the old key after the rekey. Affected
3477 file lib/silcclient/[idlist.h|client_channel.c].
3479 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3481 * Added check to the silc_server_new_id_real to not accept
3482 new ID if it is the sender's own ID. Affected file is
3483 silcd/packet_receive.c.
3485 * Assure that we do not announce ourself or the one we've
3486 sending our announcements when we're router and are announcing
3487 servers to our primary router. Affected file silcd/server.c.
3489 * Fixed silc_server_command_identify_check_client to assemble
3490 correct WHOIS packet. It send corrupted WHOIS packet and
3491 caused problem with router to router connections. Affected
3492 file silcd/command.c.
3494 Fixed also silc_server_command_whois_check the same way
3495 as for the IDENTIFY command.
3497 * Added new SilcIDListStatus to the server in the SilcIDListData
3498 structure. The status now includes the current status of
3499 the entry (like registered, resolved etc.). Affected file
3500 silcd/idlist.[ch]. Defined a bunch of different status types
3501 as well. This replaced the old boolean registered field as well.
3503 Added resolve_cmd_ident field to the SilcClientEntry structure
3504 too so that if the entry is for example being resolved so
3505 another command may attach to the same pending command reply
3506 without requiring to resolve the same entry again. This concept
3507 should optimize the WHOIS and the IDENTIFY resolving under
3508 heavy load by taking away unnecessary resolving for entries
3509 that are being resolved already.
3511 Added support for adding multiple pending commands for one
3512 command idenfier. Affected file silcd/command[_reply].[ch].
3514 * Fixed WHOIS and IDENTIFY save to remove the cache entry
3515 before deleting the data. Otherwise the hash table will have
3516 freed data in comparison functions. Affected file is
3517 silcd/command_reply.c.
3519 * Fixed silc_idlist_replace_client_id to add the new entry to
3520 the cache with NULL nickname. Otherwise there will be invalid
3521 memory as the nickname after the nickname is freed. Affected
3522 file silcd/packet_receive.c.
3524 * Fixed the silc_idlist_get_clients_by_hash. The entries was
3525 saved into wrong slots because the previous number of entries
3526 was not taken into account. Affected file silcd/idlist.c.
3527 Fixed same thing in silc_idlist_get_clients_by_nickname too.
3529 * If we are router and we receive JOIN notify to a channel that
3530 does not have any users then notified client is marked as the
3531 channel founder, as it is it. The affected file is
3532 silcd/packet_receive.c
3534 * Added to the extended hash table API's table_del_*ext functions
3535 the destructor as argument too, so that the caller can decide
3536 which destructor to use or whether to use destructor at all.
3537 Affected file lib/silcutil/silchashtable.[ch].
3539 * Fixed ID Cache purging. It actually deleted the entries from
3540 the hash table after the data was freed. The hash table ended
3541 up comparing freed memory. The affected file is
3542 lib/silccore/silcidcache.c.
3544 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3546 * Fixed Irssi SILC client's KILL command's HELP syntax.
3548 * The USERS command now resolves the detailed user information
3549 if the userinfo field is missing. Affected file is
3550 lib/silcclient/command_reply.c.
3552 * Do not print error in silc_file_read if the read file does
3553 not exist. Just silently return NULL. Affected file is
3554 lib/silcutil/silcutil.c.
3556 * Fixed the silc_log_output to not wine about NULL filename
3557 and to not create some bogus " " filename. Affected file is
3558 lib/silcutil/silclog.c.
3560 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3562 * Fixed various printing bugs on the user interface in the
3563 Irssi SILC Client. Minor changes that were forgotten from
3566 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3568 * Fixed the configure.in.pre and the compilation and distribution
3569 environment to support the new autoconf 2.52. That version is
3570 now required to compile the CVS trunk.
3572 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3574 * Renamed function silc_parse_nickname to silc_parse_userfqdn
3575 to generally parse user@fqdn format strings. Affected file
3576 lib/silcutil/silcutil.c.
3578 * Added nickname_format and nickname_force_format fields to the
3579 SilcClientParams structure. The first one defines the format
3580 for the nicknames that the library will enforce if the receives
3581 multiple same nicknames. The second one is boolean value and
3582 can be used to force the library to always enforce the format
3583 to the nicknames regardles whether there are multiple nicknames
3584 or not. This configurable formatting was employed to flexibly
3585 support accessing multiple nicknames from the user interface.
3586 The userinterface can now set the nicknames to what ever format
3587 they prefer. Affected file lib/silcclient/silcapi.h.
3589 Added function silc_client_nickname_format to the file
3590 lib/silcclient/idlist.c. It performs the nickname formatting.
3592 Added new field `hostname´ to the SilcClientEntry context.
3593 It holds the hostname of the client. Affected file is
3594 lib/silcclient/idlist.h.
3596 * Irssi SILC Client sets the nicknames in nick@hostn format.
3597 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
3598 irssi/src/silc/core/silc-core.c.
3600 The WHOIS printing now also shows both the real nickname and
3601 the formatted nickname so that user knows how to access the
3602 user if there are multiple same nicknames cached. Affected
3603 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
3604 printing formatting too to take the hostname now as a separate
3605 argument. The Affected file is
3606 irssi/src/fe-common/silc/modules-formats.[ch].
3608 * Changed the silc_client_get_clients_local to accept the formatted
3609 nickname as argument. It accepts the real nickname too but the
3610 formatted nickname can be used to find the true entry from
3611 multiple entries. Affected file lib/silcclient/silcapi.h and
3612 lib/silcclient/idlist.c.
3614 * Added nickname_format_parse field to the SilcClientParams.
3615 It is a callback function provided by the application to parse
3616 the nickname out of the formatted nickname string. The library
3617 calls it to get the nickname from the formatted string. Since
3618 the application generally knows better the format of the nickname
3619 string it parses it instead of the library, even though library
3620 encodes the formatted string. If the callback function is not
3621 provided then the library will use the string as is. The
3622 affected file is lib/silcclient/silcapi.h.
3624 * All the nickname strings passed to the client library in
3625 commands are now expected to be formatted nickname strings.
3626 If the command does not support the formatted nickname string
3627 it will assume that the sent string is the actual nickname.
3628 Affected file lib/silcclient/command.c.
3630 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3632 * Added public key authentication support to OPER and SILCOPER
3633 commands in the client library. Affected file is
3634 lib/silcclient/command.c.
3636 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3638 * Changed the get_auth_methdod client operation to be asynchronous.
3639 It can be async if the application resolves the authentication
3640 method from the server during the negotiation. Added new
3641 SilcGetAuthMeth completion callback that the application will
3642 call after resolving the authentication method.
3644 Added function silc_client_request_authentication_method that
3645 the application can use to resolve the authentication method
3646 from the server. Added also SilcConnectionAuthRequest callback
3647 that the library will call after the server has replied. The
3648 application can call this function if it does not know the
3649 current authentication method.
3651 Affected files are lib/silcclient/client.c and
3652 lib/silcclient/silcapi.h.
3654 * The Irssi SILC client now automatically resolves the authentication
3655 method incase any configuration information is not present (and
3656 currently there never is). The affected file is
3657 irssi/src/silc/core/client_ops.c.
3659 * Fixed public key authentication from the client library.
3660 Affected file lib/silcclient/protocol.c. Changed also the
3661 protocol specification about the public key authentication in
3662 the connection authentication protocol. The actual data to be
3663 signed is now computed with a hash function before signing.
3665 * Fixed the public key authentication from the server as well.
3666 Affected file silcd/protocol.c.
3668 * Removed the mlock()'s from the memory allocation routines.
3669 Affected file lib/silcutil/silcmemory.c. The ./configure does
3670 not check anymore for the mlock(). Affected file is
3673 * Fixed USERS command in server to allow the execution of the
3674 command for private and secret channels if the client sending
3675 the command is on the channel. Affected file silcd/command.c.
3677 * Fixed silc_client_get_clients_local to return the clients
3678 count correctly. It could return wrong value. Affected file
3679 lib/silcclient/idlist.c.
3681 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3683 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
3684 types. The assembler optimizations seemed not to like 64-bit
3685 data types. The assmebler optimizations thus are now enabled
3686 also for BSD systems as opposed to only enable them for Linux.
3688 * Do not check for threads at all on BSD systems. Affected
3689 file configure.in.pre.
3691 * Removed -n and -h options from the Irssi SILC Client since
3692 they are not used in silc.
3694 * Fixed the prime generation to assure that the first digit
3695 of the generated random number is not zero since our conversion
3696 routines does not like number strings that starts with zero
3697 digit. If zero digit is seen the random number is regenerated.
3698 This caused some corrupted RSA keys when the zero first digit
3699 was met. Affected file lib/silcmath/silcprimegen.c.
3701 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3703 * Fixed WIN32 configuration in the ./configure script.
3704 Fixed to include xti.h on environments that has it.
3705 Patches by Carsten Ilchmann and andrew.
3707 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3709 * Changed the silc_id_create_client_id to be collision
3710 resistant. It is now assured that there cannot be created
3711 two same client ID's. I suspect that some weird bugs in
3712 the server were actually caused by duplicate Client IDs.
3713 Affected file silcd/serverid.[ch]. A router receiving
3714 new ID now also assures and informs the sending server
3715 if the ID caused collision.
3717 * Changed the silc_id_create_channel_id to also assure that
3718 there are no collisions.
3720 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3722 * Statement about ignoring the Mutual Authentication flag when
3723 performing rekey with PFS was a bit misleading. It is ignored
3724 if it was set in the initial negotiation, it cannot be even
3725 set in the rekey. Fixed in the ke-auth draft. Started the
3726 new versions of the protocol drafts in the doc/.
3728 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3730 * Fixed a bug in silc_client_command_identify_save when saving
3731 new channel information. The channel name was no duplicated
3732 and caused crash on exit. Affected file is
3733 lib/silcclient/command_reply.c.
3735 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3737 * Fixed the getkey command handling in the server. Send just
3738 empty OK reply to the sender if the key could not be fetched
3739 (but everything else was ok, like the key just was not available).
3740 Changed the public key parameter to optional in the protocol
3741 specs so that empty OK reply can be sent. Affected file
3744 Added a message to Irssi SILC client to tell to user if the
3745 server did not return a public key.
3747 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3749 * Fixed a channel key regeneration bug. It registered new
3750 timeout tasks exponentially until all system resources were
3751 used. Affected file silcd/server.c.
3753 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3755 * Added the SILC Document generator to the scripts/silcdoc.
3756 It can be used to generate the Toolkit Reference Manual out
3757 of the source tree. Internally it will also use the RoboDoc
3758 generator now imported in util/robodoc.
3760 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3762 * Added couple of return's in rekey protocol if error orccurred
3763 during the protocol. The execution must be terminated.
3764 Affected file silcd/protocol.c. Also, terminate the protocol
3765 always with timeout.
3767 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3769 * The client's Client ID was created initally from the wrong
3770 nickname (it could have been in format nick@host) in the
3771 silc_server_new_client. Affected file silcd/packet_receive.c
3773 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3775 * Added some SILC_LOG_ERROR's to various error conditions
3776 if client could not be added to ID cache. Affected files
3777 silcd/packet_receive.c and silcd/server.c.
3779 * When client's sock->user_data is freed, NULL also the
3780 client->router and client->connection pointers. Added check
3781 for these pointers being NULL to various places around the
3782 code. Affected file silcd/server.c.
3784 * Added client->data.registered == TRUE checks to various
3785 places around the code to assure that unregistered client's
3786 are not handled when it is not allowed. Affected file
3789 * Added `bool registered' fields to all
3790 silc_idlist_[server|client]_get_* routines to indicate whether
3791 the fetched client needs to be registered or not. Affected
3792 file silcd/idlist.[ch].
3794 * Add your own entry as registered to the ID cache in the
3795 server. Affected file server.c.
3797 * Fixed a bug in silc_server_new_server. The SilcServer was
3798 set as the new server's context instead of SilcServerEntry.
3799 This naturally caused some weird bugs.
3801 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3803 * Do not delete the channel rekey task when adding it
3804 for in silc_server_create_channel_key.
3806 * Changed the silc_server_create_channel_key to return
3807 TRUE or FALSE to indicate the success of the channel key
3810 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3812 * Fixed MSVC++ project files and added missing files to
3813 Makefiles under win32/.
3815 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3817 * Do not add TCP_NODELAY flag if the operating system
3818 does not have it defined. Affected files are
3819 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3821 * Fixed buffer overflow from Irssi SILC Client. Affected
3822 file irssi/src/fe-common/core/themes.c.
3824 * Fixed double free in client library in the file
3825 lib/silcclient/client.c when disconnecting from server.
3827 * Applied double free patch from cras to Irssi SILC client.
3828 Affected files irssi/src/core/[modules/expandos].c
3830 * Fixed the disconnection handling to Irssi SILC Client.
3831 The application must call silc_client_close_connection
3832 in ops->connect client operation in case of failure of
3833 the connection. Affected file is
3834 irssi/src/silc/core/client_ops.c.
3836 * Do not set sock->protocol to NULL in the function
3837 silc_client_close_connection after executing the protocol's
3838 final callback since the sock might not be valid anymore.
3839 Affected file lib/silcclient/client.c.
3841 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3843 * Do not enable SILC_THREADS if the linking with libpthread
3844 did not happen. Affected file configure.in.pre.
3846 * Added notion to protocol specification that server must
3847 verify the sent authentication payload with CMODE when
3848 setting the channel founder key. Implemented it to the
3849 server. Affected file silcd/command.c.
3851 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3853 * Added _EXTRA_DIST SILC distribution variable to the
3854 distributions file. It is used to conditionally add extra
3855 files or directories to the specific distribution. Affected
3856 files ./prepare, Makefile.am.pre and distributions.
3858 Removed the `_' from the start of the distribution names.
3861 * Added README.WIN32 for instructions to compile the Toolkit
3864 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3866 * Fixed a double free in disconnection in the server. Affected
3867 file is silcd/server.c.
3869 * Fixed the lib/silcske/groups.c to work now also with GMP
3870 MP library. The string conversion did not work when using
3871 specific base and the base is indicated in the string as well.
3873 * Created win32/ directory which now includes MSVC++ specific
3874 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3875 It will appear only in the toolkit distribution
3877 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3879 * Changed the key material distribution function in case when
3880 the hash output is too short. The data is now concatenated
3881 a bit differently than it used to. Made the change to the
3882 SKE protocol specification.
3884 * Added better GMP detection to configure.in.pre. A patch
3887 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3889 * Fixed a minor bug in SKE that might cause some problem on
3890 some platforms. Affected file lib/silcske/silcske.c.
3892 * Added the cookie checking for initiator in the SKE. It checks
3893 that the responder returns the sent cookie unmodified. The
3894 affected file is lib/silcske/silcske.c. Added new SKE
3895 error type INVALID_COOKIE that can be sent during the
3896 negotiation. Fixed some memory leaks as well.
3898 * Added the "invalid cookie" error message to Irssi SILC client's
3901 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3903 * Added `task_max' field to the SilcClientParams to indicate
3904 the maximum tasks the scheduler can handle. If set to zero,
3905 default values are used. Affected file lib/silcclient/silcapi.h.
3907 * Fixed memory leaks in silc_client_close_connection. Affected
3908 file lib/silcclient/client.c.
3910 * Added silc_client_del_client_entry to client library to free
3911 all memory of given client entry. Affected file is
3912 lib/silcclient/idlist.[ch].
3914 * Added new functions silc_client_del_channel and
3915 silc_client_del_server to delete channel and server entries.
3916 Affected file lib/silcclient/[silcapi.h/idlist.c].
3918 * Removed silc_client_del_client_by_id from silcapi.h.
3920 * Fixed the INFO command to return the server's own info
3921 correctly when querying by Server ID. Affected file is
3924 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3926 * Removed the non-blocking settings in WIN32 code in the
3927 silc_sock_[read/write] and added SleepEx instead. Affected
3928 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3929 of input data is now checked with FIONREAD and ioctlsocket.
3931 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3933 * Call silc_schedule_task_del_by_context in the
3934 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3935 Affected file lib/silccore/silcprotocol.c.
3937 * Call silc_protocol_cancel for active protocols in the
3938 silc_server_close_connection if the funtion
3939 silc_server_free_sock_user_data has not been called.
3940 Affected file silcd/server.c.
3942 * Generic tasks cannot be deleted using the del_by_fd
3943 task deleting function since generic tasks does not match
3944 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3946 * Added a notion to SILCOPER help file that the SILCOPER works
3947 only on router server, not on normal server.
3949 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3951 * Added for WIN32 support for the new scheduler as well.
3952 Affected file lib/silcutil/win32/silcwin32schedule.c.
3954 * Fixed the SHA1 implementation to work on various platforms.
3956 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3958 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3959 API. It is part of the scheduler now. Everything else is
3960 as previously but some functions has changed their names.
3961 Checkout the lib/silcutil/silcschedule.h for the interface.
3962 Updated all applications to use the new interface. Affected
3963 files are lib/silcutil/silcschedule.[ch].
3965 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3967 * Found a bug in the SKE implementation. The HASH value,
3968 specified by the protocol, was not computed correctly. The
3969 public key of the responder was not added to the computation
3970 even though it is mandatory. Affected file lib/silcske/silcske.c.
3971 This unfortunately causes incompatibilities with older
3972 clients and servers.
3974 * Added WIN32 specific network init and uninit functions:
3975 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3976 the Winsock2. Affected file lib/silcutil/silcnet.h and
3977 lib/silcutil/win32/silcwin32net.c.
3979 * Set the socket always to nonblocking mode on WIN32 after
3980 reading data or writing data. Affected file is
3981 lib/silcutil/win32/silcwin32sockconn.c.
3983 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3985 * Fixed various compilation problems under WIN32. Affected
3986 files lib/silcutil/win32/silcwin32thread.c and
3987 lib/silcutil/win32/silcwin32schedule.c.
3989 * Removed all _internal.h #includes from public header
3990 files. Internal headers must never be included from
3993 Removed also the lib/silcske/payload_internal.h file.
3995 * All include files that may be needed (public and some others
3996 included by the public headers) by application developers are
3997 now copied to the ./includes directory. It does not copy any
3998 internal headers. Affected file Makefile.defines.pre and all
3999 Makefile.am's under lib/ and subdirs.
4001 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4003 * Do not change the ~/.silc directory's permissions automatically.
4004 Affected file irssi/src/silc/core/clientutil.c.
4006 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4008 * Do not cancel the protocol in silc_server_close_connection
4009 it might cause recursion. Now cancelled in the function
4010 silc_server_free_sock_user_data. Affected file silcd/server.c.
4012 * Fixed the silc_server_remove_clients_by_server to regenerate
4013 the channel keys correctly finally. Added also new function
4014 silc_server_remove_clients_channels to actually do it.
4015 Affected file silcd/server.c.
4017 * Fixed the silc_server_new_channel to not crash by giving
4018 wrong router to the new channel. Affected file is
4019 silcd/packet_receive.c.
4021 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4023 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
4024 which is given as argument to the silc_client_alloc now.
4025 It can be used to configure the client and set various parameters
4026 that affect the function of the client.
4028 * The USERS command in server did not check whether the channel
4029 is private or secret. Affected file silcd/command.c.
4031 * Added new argument to the USERS command in protocol specification.
4032 The USERS command now can take the channel name as argument
4033 as well. Added support for this in client and server and
4034 updated the protocol specs.
4036 * Completed the GETKEY command in client. It can be now used
4037 to fetch also servers public key not only some clients.
4038 Affected files lib/silcclient/command[_reply].c.
4040 * Added silc_client_get_server to return server entry by the
4041 server name. Affected files lib/silcclient/silcapi.h and
4044 * Redefined the IDENTIFY command in protocol specification to be
4045 more generic. It now can be used to query information about
4046 any entity in the SILC Network, including clients, servers and
4047 channels. The query may be based either the entity's name
4048 or the ID. Added support for this in both client and server.
4050 Affected files silcd/command.c and lib/silcclient/command.c
4051 and command_reply.c.
4053 * Optimized the WHOIS and WHOWAS commands in the server. Removed
4054 the _from_client and _from_server functions. Affected file
4057 * Added silc_client_get_channel_by_id_resolve to the file
4058 lib/silcclient/silcapi.h to resolve channel information by
4059 its ID. Added also silc_client_get_channel_by_id that
4060 does not resolve it from the server.
4062 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4064 * Added SilcServerEntry context into the client library
4065 to represent one server. The INFO command now allocates
4066 these to save the resolved server info. For now on the
4067 client library will also keep information about servers,
4068 connected and resolved with INFO.
4070 The INFO command now allocates the SilcServerEntry context
4071 and saves the server info there. The COMMAND_REPLY in
4072 the INFO now returns the parameters to application in
4073 same order as defined in the protocol specification.
4075 The entries are cached in the client->server_cache.
4077 * The INFO command is now issued after received the Client ID
4078 from the server. Affected file lib/silcclient/client.c.
4080 * The CMODE_CHANGE notify may now return also an SilcServerEntry
4081 to the application as the mode changer might be server.
4082 It is guaranteed that NULL is not returned anymore to the
4083 application. Affected file lib/silcclient/client_notify.c.
4085 The ID Type is now also passed to the application so that
4086 it can check whether the returned entry is SilcClientEntry
4089 Added new function silc_client_get_server_by_id to return
4090 the server entry by ID. Affected files are the
4091 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
4093 * Do not create the channel in the Irssi SILC Client when issuing
4094 the JOIN command but when received the sucessful JOIN command
4095 reply. Otherwise the channel might get created even though we
4096 could not join it. The Affected file is
4097 irssi/src/silc/core/[silc-channels.c/client_ops.c].
4099 * Fixed a channel joining bug in router. The router must also
4100 check the channel modes, invite and ban lists etc. when serving
4101 the JOIN command sent by normal server. Affected file is
4102 silcd/command.c. The router now resolves the client's
4103 information from the server who sent the JOIN command if it
4104 does not know it, and processes the JOIN command only after
4107 * Changed the SilcCommandCb to take new argument; void *context2.
4108 Affected file lib/silccore/silccommand.h
4110 The second argument in the command callbacks in the server now
4111 includes the SilcServerCommandReplyContext if the command was
4112 called as pending command callback from the command reply.
4113 Otherwise it is NULL. When called as pending the status of the
4114 command reply will be checked and if it was erronous the
4115 error will be sent to the original sender of the command.
4116 This way the client always receives the error messages even
4117 though the server was actually the one who received the error
4118 when it resent the command to router, for example. Affected
4119 files silcd/command[_reply].[ch].
4121 * Fixed sending WHOWAS command's error message to client if
4122 the requested client could not be found. It was missing.
4125 * Changed the CMODE and CUMODE commands reply arguments in the
4126 protocol specification. The Channel ID is now sent in both
4127 of the commands to identify the channel. Implemented this
4128 new feature to the client and server. Affected files
4129 lib/silcclient/command_reply.c and silcd/command.c.
4131 * Made better checks for invite and ban lists in the JOIN
4132 command in server. Affected file silcd/command.c.
4134 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4136 * The server now performs the incoming host IP/DNS lookup
4137 using the silc_socket_host_lookup and thus does not block
4138 the server anymore. Affected file silcd/server.c.
4140 * Completed the multi-thread support for SILC Scheduler in
4141 the lib/silcutil/silcschedule.c.
4143 * Fixed the configure.in.pre to detect the pthread correctly
4146 * Fixed a deadlock in silc_task_queue_wakeup in the file
4147 lib/silcutil/silctask.c.
4149 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4151 * Added new function silc_schedule_wakeup that is used in
4152 multi-threaded environment to wakeup the main thread's
4153 schduler. It needs to be used when a thread adds a new task
4154 or removes a task from task queues. After waking up, the
4155 scheduler will detect the task queue changes. If threads
4156 support is not compiled in this function has no effect.
4157 Implemented the wakeup mechanism to both Unix and WIN32
4158 systems. Affected files are lib/silcutil/silcschedule.[ch],
4159 lib/silcutil/unix/silcunixschedule.c and the
4160 lib/silcutil/win32/silcwin32schedule.c.
4162 * Added new function silc_task_queue_wakeup to wakeup the
4163 scheduler by the specified task queue. Affected file
4164 lib/silcutil/silctask.[ch].
4166 * The silc_socket_host_lookup_start now wakes up the scheduler
4167 after adding the timeout task. Affected file is
4168 lib/silcutil/silcsockconn.c.
4170 * The silc_socket_host_lookup is synchronous now if the threads
4171 support is not compiled in. However, the callback is still
4172 called asyncronously through the scheduler, anyway. Affected
4173 file lib/silcutil/silcsockconn.c.
4175 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4177 * Added new function silc_socket_host_lookup to perform
4178 asynchronous IP and FQDN lookups for the socket connection.
4179 Affected files lib/silcutil/silcsockconn.[ch].
4181 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4183 * Added SILC_MUTEX_DEFINE to define the mutex on environments
4184 that may or may not compile the mutex support in.
4186 Changed the silc_mutex_alloc interface. It allocates the
4187 mutex now to the sent pointer and returns TRUE or FALSE.
4189 Affected file lib/silcutil/silcmutex.h.
4191 * Wrote the SILC Task Queue interface to support multi-threads.
4192 Affected file lib/silcutil/silctask.[ch].
4194 * Wrote the SILC Scheduler to support multi-threads. Affected
4195 file lib/silcutil/silcschedule.c.
4197 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4199 * Implemented the SILC Mutex API and SILC Thread API for WIN32
4200 in lib/silcutil/win32/.
4202 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4204 * Defined SILC Mutex API and SILC Thread API and implemented
4205 them for Unix. Affected files are
4206 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
4207 lib/silcutil/unix/silcunixmutex.c and
4208 lib/silcutil/unix/silcunixthread.c.
4210 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4212 * Fixed the silc_server_remove_clients_by_server's channel
4213 key re-generation. The hash table handling was incorrect
4214 and would not work with many channels. Affected file is
4217 * Fixed some memory leaks around the server code.
4219 * Rewrote the silc_server_get_users_on_channel to support IPv6
4220 based Client ID's. Affected file silcd/server.c.
4222 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
4223 specification. However, a separate document must be written
4224 to define the detailed signing procedure and the payload
4225 associated with the flag. Defined the flag to the
4226 lib/silccore/silcchannel.h as well.
4228 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4230 * Changed the dynamic tables to static size tables in the
4231 lib/silccrypt/silchmac.c.
4233 * Removed GCC dependencies from the code. A patch by cras.
4235 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4237 * Do not show the error "Error receiving packet bla bla"
4238 in server if it really was not an error (-2 means that reading
4239 is pending). Affected file silcd/server.c.
4241 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4243 * Fixed a possible crash in silc_server_remove_clients_by_server
4244 in silcd/server.c. Fixed there also some memory leaks.
4246 * Fixed the silc_idlist_replace_client_id. It could replace
4247 wrong key in the hash table. Affected file silcd/idlist.c.
4249 * Do not check whether there are global users on the channel
4250 if the channel->global_users is FALSE. Affected functions
4251 silc_server_remove_from_one_channel and
4252 silc_server_remove_from_channels in silcd/server.c. Also,
4253 do not check if the removed client is local as we can be
4254 sure that global client was not removed from the channel
4255 and checking for global users is not needed.
4257 * The silc_server_remove_clients_by_server now re-generates
4258 the channel keys correctly for those channels that had
4259 clients removed from them. Affected file silcd/server.c.
4261 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4263 * Found the reason of random crashes in the server. We weren't
4264 ignoring the SIGPIPE signal (which can be sent in write())
4265 and it crashed the server. Affected file silcd/silcd.c.
4267 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4269 * Assure that sock->user_data is not NULL in the function
4270 silc_server_packet_send in silcd/packet_send.c.
4272 * Disconnect the remote connection if it could not be added
4273 to any ID lists in the server. The affected file is
4276 * Check in silc_server_packet_send[_real/dest] that the
4277 socket is not disconnecting and ignore the data if it is.
4278 Affected file silcd/packet_send.c.
4280 * Define inline to __inline on native WIN32 compilation.
4281 Affected file includes/silcwin32.h.
4283 * Added some explicit type casts for inline code since MSVC
4284 require them. Affected files lib/silcutil/silcbuffer.h,
4285 lib/trq/silcdlist.h and lib/trq/silclist.h.
4287 * Print warning in log files from now on if the packet
4288 decryption fails. Affected file silcd/server.c.
4290 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4292 * Changed the `say' client operation's interface to accept
4293 new `type' argument to indicate the type of the message sent
4294 by the library. The application may filter the library's
4295 messages according the type. The affected file is the
4296 lib/silcclient/silcapi.h.
4298 * Added two new functions to lib/silcclient/silcapi.h:
4299 silc_client_del_client and silc_client_del_client_by_id.
4300 Affected file lib/silcclient/idlist.c.
4302 * Moved the clientincludes.h from includes/ to silc/ and
4303 serverincludes.h from includes/ to silcd/.
4305 * The modes for the CMODE and CUMODE are now passed as
4306 uint32 for application with COMMAND_REPLY. The affected
4307 file is lib/silcclient/command_reply.c.
4309 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4311 * /WHOIS without arguments shows client's own information.
4312 Affected file lib/silcclient/command.c.
4314 * Changed PING to not accept any arguments. The specs
4315 says that client can ping only the connected server so
4316 requiring an argument is not needed. Affected file is
4317 lib/silcclient/command.c.
4319 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4321 * Fixed a fatal bug in private message sending and reception
4322 encryption and decryption when using private message keys.
4323 The implementation was incorrect and did not follow the
4324 specification. It causd that some of the message were
4325 lost since it did not use the sending and receiving keys
4326 as the protocol suggests. This has been fixed and will cause
4327 incompatibilities with older clients when sending private
4328 message encrypted with private message keys. Affected files
4329 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
4330 and various other in Irssi SILC Client.
4332 Added `responder' boolean argument to the functions
4333 silc_client_add_private_message_key[_ske] to indicate when
4334 the key is added as responder or initiator of the key
4337 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4339 * Removed the silc_ske_check_version function and created
4340 a SilcSKECheckVersion callback. Added also a function
4341 silc_ske_set_callbacks that is now used to set all SKE
4342 callbacks. The callback functions are not given to
4343 the SKE functions anymore, but this function is used to
4346 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
4348 * Added `silc_version' argument to the silc_client_alloc
4349 to define the version of the application for the library.
4350 The library will use the version string to compare it
4351 against the remote host's (usually a server) version
4352 string. Affected file lib/silcclient/silcapi.h
4354 * Added the KE protocol context to Key Agreement context
4355 in client library so that we can abort the SKE if it
4356 is in process when we get timeout. Affected file is
4357 lib/silcclient/client_keyagr.c.
4359 * Do not resolve the client ID forever if it returns in the
4360 first time that such client does not exist. This was done
4361 for example with private message. Affected file is
4362 lib/silcclient/client_prvmsg.c.
4364 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4366 * Do not add regex.h for WIN32. The affected file
4367 includes/silcincludes.h.
4369 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
4370 not work yet 100%. It generates the DLL's automatically
4371 when compiling with --with-win32 under cygwin.
4373 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4375 * lib/contrib/regex.c is not compiled on WIN32.
4377 * Added silc_net_get_socket_opt function to the
4378 lib/silcutil/silcnet.h.
4380 * Added includes/silcwin32.h for WIN32 specific includes
4383 * Do not use ptime structure or any of the posix process
4384 functions on WIN32 in lib/silccrypt/silrng.c.
4386 * Added silc_gettimeofday to provide generic function
4387 for struct timeval on all platforms. Added the function
4388 to lib/silcutil/silcutil.h.
4390 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4392 * Moved the lib/silccore/silcsockconn.[ch] to the utility
4393 library as they clearly belong there. As a plus side we
4394 can make the actual socket connection routines platform
4397 Added also new generic function silc_socket_read and
4398 silc_socket_write (that used to be silc_packet_[read/write].
4399 The implementation of these are platform specific.
4401 * Added WIN32 specific routines of silc_socket_[read/write]
4402 to lib/silcutil/win32/silcwin32sockconn.c.
4404 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4406 * Added preliminary support for native WIN32 compilation under
4407 cygwin (using the -mno-cygwin option for GCC) to the
4408 ./configure.in.pre. The --with-win32 now prepares the
4409 compilation for native WIN32.
4411 * Rewrote the SILC Scheduler interface in the file
4412 lib/silcutil/silcschedule.h. The scheduler is now context
4413 based and does not have anymore any global static scheduler.
4414 Moved the Unix scheduler to the lib/silcutil/unix/ directory
4415 and created lib/silcutil/win32 directory for WIN32 based
4418 * Added Unix specific network routines to the
4419 lib/silcutil/unix/silcunixnet.c and the old
4420 lib/silcutil/silcnet.c includes now only generic routines.
4422 Added WIN32 specific network routines to the
4423 lib/silcutil/win32/silcwin32net.c.
4425 * Added Unix specific utility functions from the
4426 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
4428 * Added WIN32 SILC Scheduler to the file
4429 lib/silcutil/win32/silcwin32schedule.c. The code is of course
4432 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4434 * Do not handle JOIN notify in the server if the target client
4435 is not registered (idata->registered == FALSE). The affected
4436 file is silcd/packet_receive.c.
4438 * Update the nickrec->founder in event_cumode in the Irssi SILC
4439 client. Affected file irssi/src/silc/core/silc-channels.c.
4441 * Fixed the CUMODE_CHANGE notify handling in the server when
4442 server and router are announcing their clients on channels.
4443 Now the mode changes are saved and notified correctly. The
4444 affected file is /silcd/packet_receive.c.
4446 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
4447 They really did not replace the cache entry in the ID Cache.
4448 Now they do that. Affected file silcd/idlist.c.
4450 * Fixed the KICK notify handling in the Irssi SILC client to
4451 update the channel records so that the kicked client does not
4452 appear to be on the channel. The affected file is
4453 irssi/src/silc/core/silc-channels.c.
4455 * Always update the conn->current_channel when executing command
4456 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
4458 * Fixed the KILL notify handling in Irssi SILC client to remove
4459 the killed client on all channels.
4461 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4463 * Fixed the silc_parse_command_line to remove extra spaces
4464 from the start and end of the arguments. Affected file is
4465 lib/silcutil/silcutil.c.
4467 * Cancel and free any active protocol in the function
4468 silc_server_close_connection. Affected file silcd/server.c.
4470 * Cancel and free any active protocol in the function
4471 silc_client_close_connction. Affected file is
4472 lib/silcclient/client.c.
4474 * Do not execute the KILL command for clients that are in
4475 history (ie. they are not in the network). Affected file is
4478 * Fixed KILL notify handling, client does not crash anymore.
4479 Affected file irssi/src/silc/core/silc-channels.c.
4481 * Reduced the default packet buffer size from 2048 to 1024 in
4482 lib/silccore/silcpacket.c.
4484 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
4485 counter to the SKE context that is incresed when the SKE library
4486 performs async operation outside the library. If the outside
4487 process frees the SKE context and FREED status will be set
4488 and the library will detect after the sync operation that the
4489 libary is freed. The affected files are
4490 lib/silcske/silcske[_status].[ch].
4492 * Resolve the client entry information in the function
4493 silc_client_channel_message to assure that NULL pointer is not
4494 passed as client entry to the application. */
4496 * Fixed the task timeout calculation to assure that there is
4497 never negative timeouts. The affected file is
4498 lib/silcutil/silcschedule.c.
4500 * Fixed the channel user mode notification sending in server.
4501 It was sent point-to-point to the router (or to server by router)
4502 but it needs to be destined to a channel. The routines now
4503 supports sending the channel user mode notifys to the channels
4504 when announcing clients and channels. Affected files are
4505 silcd/server.c and silcd/packet_receive.c.
4507 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
4508 It did not actually replace the old channel entry in the cache.
4509 Affected file lib/silcclient/client_notify.c.
4511 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4513 * Fixed a possible crash in silc_packet_send_prepare. It now
4514 assures always that there is enough space in the buffer and
4515 at the tail area of the buffer (for MAC).
4517 Fixed the inbound buffer reallocation in silc_packet_read.
4518 It was old code and did not handle the reallocation correctly.
4521 The affected file is lib/silccore/silcpacket.c.
4523 * Fixed buffer overflow in silc_parse_nickname in the file
4524 lib/silcutil/silcutil.c.
4526 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4528 * make install generates new server keys only if there is not
4531 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4533 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
4534 Added check that if the NOREPLY is set then we will not send
4535 the away message. This avoids infinite loop of away messages
4536 if both clients are away. The affected file is
4537 lib/silcclient/client_prvmsg.c.
4539 * Fixed client crash if /NICK was given without arguments.
4540 Affected file lib/silcclient/command.c.
4542 * Server does not send the invite list in INVITE command back
4543 to the client if the list was not altered. Added this notion
4544 to the protocol spec as well. Affected file silcd/command.c.
4546 Fixed possible crash in INVITE command by checking the
4547 value of silc_server_get_client_route command.
4549 * Fixed the INVITE notify type handling. The arguments are now
4550 taken in correct order and client does not crash. The affected
4551 file is irssi/src/silc/core/silc-channels.c.
4553 Removed the "Inviting xxx to channel" message from the
4554 client library away and let the application handle it.
4555 Affected file lib/silcclient/command.c. Added that message
4556 to Irssi SILC client's message formats.
4558 * Fixed CMODE command crash in client. It now checks the
4559 amount of arguments correctly and does not crash. The affected
4560 file is lib/silcclient/command.c.
4562 * Do not create new channel automatically in silc_channels_join
4563 but check whether the channel by that name already exists.
4564 Affected file irssi/silc/core/silc-channels.c.
4566 * Do not send the SERVER_SIGNOFF to router if the disconnected
4567 entity was the router. Affected file silcd/server.c.
4569 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
4570 SILC client as it was missing from there.
4572 Added the handling of the KICK notify to the Irssi SILC client
4573 as it was missing. Added "you have been kicked" message to
4574 Irssi SILC client's message modules formats.
4576 Added the handing of the KILL notify to the Irssi SILC client
4577 as it was missing. Added the kill message module formats
4580 The affected file is irssi/src/silc/core/silc-channels.c.
4582 * The router did not save the channel mode the server announced.
4583 Affected file silcd/packet_receive.c.
4585 * Fixed a possible crash in INFO command in server. If the
4586 server did not provide the server info it crashed. Affected
4587 file silcd/command.c.
4589 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4591 * Fixed the GETKEY command in the server to check also the
4592 global list. Otherwise the GETKEY would not work correctly
4593 in normal SILC server. Affected file silcd/command.c.
4595 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4597 * Fixed GETKEY crash, it crashed if the command did not succseed.
4599 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4601 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
4602 is now real and not just an macro interface to GMP.
4604 Removed the entire GMP from the source tree and imported new
4605 NSS MPI library instead. Reason for removing GMP is that it is
4606 extremely large and compiles extremely slow. The NSS MPI
4607 is only a few files and compiles in less than 10 seconds.
4608 The speed is also about the same as GMP. The MPI is imported
4609 to lib/silcmath/mpi.
4611 If the system has GMP installed we will still use the GMP.
4612 If it is not then the NSS MPI will be compiled.
4614 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4616 * Merged a long nickname (127 characters long) crash bugfix from
4617 Irssi CVS tree. Affected file irssi/src/core/misc.c.
4619 * Merged a freed memory reference bugfix from Irssi CVS tree.
4620 Affected file irssi/src/core/commands.c.
4622 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4624 * Added the server's public key sving and verification to the
4625 server when performing the SKE. This was missing and the
4626 remote server's (or router's) public key was accepted without
4627 checking whether we have it previously or trust it at all.
4628 Affected file silcd/protocol.c.
4630 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4632 * Check in the silc_server_timeout_remote if protocol is active
4633 and make sure that the protocol's final callback is called so
4634 that all memory if freed. Affected file silcd/server.c.
4636 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4638 * silc_server_whois_send_reply crashed the server if the nickname
4639 was 127 characters long. Affected file silcd/command.c.
4641 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4643 * Added sanity check to the silc_server_new_client. If the hostname
4644 is provided inside username then check that the provided hostname
4645 really is the same as the resolved one. If the hostname was not
4646 resolved then check it from the public key. Affected file is
4647 silcd/packet_receive.c.
4649 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
4650 if the server disconnected us and the connection is not valid
4651 anymore. Affected file irssi/src/silc/core/silc-channels.c.
4653 * Moved the silc_client_[chmode|chumode|chumode_char] away from
4654 the library to the lib/silcutil/silcutil.[ch].
4656 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4658 * Close log file after open. Affected file
4659 lib/silcutil/silclog.c.
4661 * Check whether sock == NULL in silc_client_send_packet and return
4662 if it is. Affected file lib/silcclient/silcclient.c.
4664 * Check rec->entry == NULL in the Irssi SILC Client before
4665 sending the channel message. Affecte file is
4666 irssi/src/silc/core/silc-servers.c.
4668 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4670 * Merged a splitted window bugfix from Irssi CVS tree. The
4671 affected file is irssi/src/fe-text/textbuffer-view.c.
4673 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
4674 It did not print nickname.
4676 * Improved the distributions system a bit.
4678 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4680 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
4681 irssi/src/fe-text/gui-window.c.
4683 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
4684 to in-active server. The affected file is
4685 irssi/src/silc/core/client_ops.c.
4687 * Resolve the client in USERS command reply if the entry does
4688 not have username resolved. The affected file is
4689 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
4690 command to WHOIS command to really resolve stuff. The USERS
4691 is not used any more in any critical section so WHOIS can
4692 be used even though it might be slower than IDENTIFY.
4694 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
4697 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4699 * Changed the protocol API a bit more consistent in the
4700 lib/silccore/silcprotocol.[ch].
4702 * Changed the following headers to ROBODoc format:
4704 lib/silccore/silcpayload.h
4705 lib/silccore/silcprotocol.h
4706 lib/silccore/silcsockconn.h
4708 All core library headers are now formatted.
4710 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4712 * Fixed a bug in Irssi SILC client; do not show that you are
4713 server/router operator if you really are not. Affected file is
4714 irssi/src/silc/core/client_ops.c.
4716 * Renamed silc_command_free_payload to silc_command_payload_free.
4717 Affected file lib/silccore/silccommand.h
4719 * Added silcmath.h to include the prototoypes of various routines
4720 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
4723 * Changed the following headers to ROBODoc format:
4725 lib/silccore/silcchannel.h
4726 lib/silccore/silccommand.h
4727 lib/silccore/silcid.h
4728 lib/silccore/silcidcache.h
4729 lib/silccore/silcmode.h
4730 lib/silccore/silcnotify.h
4731 lib/silccore/silcpacket.h
4732 lib/silcmath/silcmath.h
4734 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4736 * Added checking to the server code not to start the server if
4737 ciphers and stuff are not configured properly. Affected files
4738 silcd/serverconfig.[h] and silcd/server.c.
4740 * Changed the layout of the header files of the public interfaces
4741 in the SILC libraries. The new layout supports ROBODoc
4742 documentation tool (and some others) so that it is easy to create
4743 a library reference manual. All the other headers and source
4744 code must still follow the CodingStyle document. Also source
4745 code must not include these ROBODoc stuffs, only the headers.
4746 Furthermore, all public interface headers must now be named
4747 by using `silc' prefix, example: silcapi.h, silccipher.h.
4748 Some files were renamed due to this. All the other headers
4749 must not be used as public interfaces. I will update the
4750 CodingStyle document later. Changed following headers, so far:
4752 lib/silcclient/silcapi.h
4753 lib/silccore/silcauth.h
4754 lib/silccore/silcprivate.h
4755 lib/silccrypt/silcdh.h
4757 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4761 * Removed silc_client_packet_send_flush from the client library
4762 as it is not needed. Affected file lib/silcclient/client.[ch].
4764 * Added printing of message of unresolved authentication method
4765 to the Irssi SILC client. Added it to the module formats.
4766 Removed the same message from the client library.
4768 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4770 * Added new distribution feature, DISTLABEL. Every distribution
4771 can define own preprocessor label that can be used in the
4772 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
4773 file distributions, acconfig.h.pre and prepare.
4775 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4777 * Added Makefile.defines_int to include the actual definitions
4778 for Makefile.defines.in. Tested the new distribution system,
4779 created distributions and tested installation.
4781 * Added AWAY message printing to the Irssi SILC client. Added
4782 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
4784 * Added SCONNECT command to call the SILC's CONNECT command.
4785 Cannot use CONNECT directly since Irssi uses that internally.
4786 Affected file irssi/src/silc/core/silc-servers.c.
4788 Added ACTION local command. It is same as ME command but takes
4789 the channel as mandatory argument.
4791 Rewrote some of the Irssi's help files to suite for SILC
4794 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4796 * Added Makefile.defines[.in] that should for now on be included
4797 in all Makefile.am file in the source tree. That file includes
4798 all common compilation definitions for SILC source tree.
4800 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4802 * Minor changes to the ./prepare script to change the package
4803 name according the distribution name to the configure.in.
4805 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4807 * Created new distribution system. Added file `distributions'
4808 that defines all the distributions that can be created out of
4809 the SILC source tree. The ./prepare script now reads that
4810 file to determine how to prepare the distributions. The
4811 first argument to the ./prepare is the name of the distribution
4812 and second is the version of the distribution. If given
4813 without arguments it creates the default (toolkit) distribution
4814 with the default version (defined in ./prepare).
4816 All Makefile.am files that are subject to the distributions
4817 are now named as Makefile.am.pre. These are ./Makefile.am
4818 and lib/Makefile.am. Others may be changed later.
4820 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4822 * Added invite list, ban list, some key management and connection
4823 error message printing to module formats in the Irssi SILC client.
4825 * Added new silc_client_set_away_message to set the away message
4826 that is back to the person who sent private message. The
4827 affected file lib/silcclient/silcapi.h and the
4828 lib/silcclient/client_prvmsg.c.
4830 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4832 * Fixed the private message sending in the Irssi SILC client,
4833 added local command KEY to the Irssi SILC client.
4835 Added key management and key agreement message formats to the
4836 irssi/src/fe-common/silc/module-formats.[ch].
4838 Added USERS (alias WHO) printing, server/router operator
4839 indication and LIST command printing to the module formats.
4841 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4843 * Fixed channel joining notify handling, cumode notify handling
4844 from Irssi SILC client.
4846 * Added SILC specific module-formats to the Irssi SILC client so
4847 that SILC specific message hilighting, colors etc is possible.
4848 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4850 Added channel mode, channel user mode, actions, notices,
4851 whois and whowas printing to the the module-formats.c.
4853 * Fixed a bug in channel deletion in the server. The channel
4854 is not left to the cache even if the channel founder auth mode
4855 is set when there are no users anymore on the channel. Affected
4856 file silcd/server.c.
4858 * The silc_net_localhost now resolves the entire hostname including
4859 the domain name. Affected file lib/silcutil/silcnet.c.
4861 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4863 * Changed the ask_passphrase client operation to be ascynchronous.
4864 It has now a completion callback and a context that the
4865 application must call after it has got the passphrase from
4866 the user. Affected files lib/silcclient/silcapi.h,
4867 lib/silcclient/protocol.c, lib/silcclient/command.c and
4870 Added SilcAskPassphrase callback that the application calls
4871 to deliver the passphrase to the library.
4873 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4874 The public key verification and especially a certificate
4875 verification is asynchronous procedure.
4877 Added new SILC_SKE_STATUS_PENDING status to indicate the
4878 request is pending and a callback will be called to finalize
4881 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4882 indicate that remote end did not send its public key (or
4883 certificate), even though we require it. Added check for this
4884 condition in the SKE. This was a security bug, now fixed.
4886 Defined new SilcSKEVerifyCbCompletion callback that is called
4887 when the verification process is completed.
4889 The affected files lib/silcske/silcske_status.h and
4890 lib/silcske/silcske.[ch].
4892 * Changed the verify_public_key client operation to be async
4893 as well. Defined SilcVerifyPublicKey callback that is used to
4894 indicate the success of the public key verification process.
4896 Changed the server and client to use the new async client
4899 * Changed the Irssi SILC client's internal scheduler to be called
4900 twice as many times as it used to be. As a result the client
4901 should be a bit faster now. Affected file is
4902 irssi/src/silc/core/silc-core.c.
4904 * Added support to Irssi SILC client of asynchronous public key
4905 verification and passphrase inquiry. Affected file is
4906 irssi/src/silc/core/silc-core.c.
4908 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4910 * Do not say "You have left channel %s" in client library.
4911 Moved it to the application. Affected files are
4912 lib/silcclient/command.c and silc/client_ops.c.
4914 * Fixed silc_client_get_clients. Command context was not
4915 duplicated and was freed memory in the callback. Affected
4916 file lib/silcclient/idlist.c.
4918 * Do not say "you are now talking..." on JOIN command in the
4919 client library. The appliation must handle it.
4921 * Do not say ".. changed topic to" in command reply in the
4922 client libary. The application must handle it.
4924 * Fixed TOPIC command sending in the client library.
4926 * Fixed a memory leak in silc_client_command_free in the file
4927 lib/silcclient/command.c.
4929 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4931 * Imported a modified version of Irssi client to the source tree.
4932 The Irssi will be used to create a new client called
4933 Irssi SILC. Imported to irssi/.
4935 Added silc_core_init_finish function to the Irssi. Affected
4936 file irssi/configure.in.
4938 A lot changes in the Makefile.ams around the irssi tree.
4940 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4942 * Do not rehash if the new size is same as the old size of the
4943 hash table, in the silc_hash_table_rehash*. The affected file
4944 lib/silcutil/silchashtable.c.
4946 * Replaced hash_table_del_by_context calls from the server
4947 (when channel->user_list and client->channels) to the
4948 hash_table_del as it is sufficient and faster.
4950 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4952 * Added silc_hash_table_list, silc_hash_table_get and the
4953 SilcHashTableList structure to provide an alternative way to
4954 traverse the hash table. The affected files are
4955 lib/silcutil/silchashtable.[ch].
4957 * Changed the server's idlist routines to use the hash table
4958 routines to optimize the code.
4960 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4962 * Replaced the client entry's `channel' list and channel entry's
4963 `user_list' list to hash tables for optimized lookup. Changed
4964 the code to use the hash table interface around the code.
4965 Affected file lib/silcd/idlist.[ch].
4967 * Added `auto_rehash' boolean argument to the function
4968 silc_hash_table_alloc to indicate whether the hash table should
4969 auto-rehash when it thinks is appropriate time. It will
4970 increase the hash table size if the there is twice as much
4971 entries in the table than the size of the table, and will
4972 decrease the size if there are twice as less entries than
4973 the size of the table.
4975 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4977 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4979 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4981 * silc_idcache_purge_by_context deletes the entry now by context
4982 as it is supposed to do. Affected file lib/silccore/idcache.c.
4984 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4985 client is not anymore valid (WHOWAS givens the info) and not
4986 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4988 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4990 * Removed the `data' and `data_len' arguments from the ID Cache
4991 interfaces and added `name' argument. ID Cache does not handle
4992 anymore the binary data only a names associated with given ID.
4994 * When hashing a Client ID with silc_hash_id the entire ID is
4995 not hashed anymore, instead only the hash of the Client ID is
4996 hashed. This way we can access the Client ID from the cache
4997 with Client ID but with the hash of the ID (which is a hash of
4998 the nickname) as well without any difference in performance.
5000 Added also silc_idcache_find_by_id_one_ext to do one on one
5001 searching when we have the actual ID. Added also function
5002 silc_hash_client_id_compare. The affected files are
5003 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
5005 * When hashing the name associated with a ID it is always done
5006 in lowercase. This way we can access the cache without worrying
5007 about case-sensitivity, even though, for example nicknames are
5010 * Fixed a bug in server with channel message sending. It put
5011 wrong ID type as destination ID. The affected file
5012 silcd/packet_send.c.
5014 * silc_idcache_del_by_context now deletes from all hash tables
5015 by context. Affected file lib/silccore/idcache.c.
5017 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5019 * Changed the client library to use the new ID Cache interface.
5020 Changes around the source tree.
5022 * Added silc_hash_table_rehash_ext to rehash with specific
5023 hash function. Affected file lib/silcutil/silchashtable.[ch].
5025 * Added silc_hash_string_compare to compare two strings in the
5026 hash table. Affected file lib/silcutil/silcutil.[ch].
5028 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5030 * Added new function silc_idcache_del_by_context into the
5031 lib/silccore/idcache.[ch].
5033 * Changed the server's ID list routines to use the new ID Cache
5034 interface. Changes around the source tree.
5036 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5038 * Added silc_hash_table_del[_by_context]_ext functions in to the
5039 lib/silcutil/silchashtable.[ch].
5041 Removed silc_hash_table_find_all* routines and added new
5042 silc_hash_table_find_foreach to replace them.
5044 Added silc_hash_table_replace_ext function as extended
5045 replacing function. Separated the simple hash table interface
5046 from the extended hash table interface in the file
5047 lib/silcutil/silchashtable.h.
5049 * Fixed minor bugs and changed it to use some of the new
5050 hash table functions in lib/silccore/idcache.c
5052 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5054 * Added new function silc_hash_table_find_all to return all keys
5055 in the hash table by the specified key. As the hash table is
5056 collision resistant it also makes it possible to have several
5057 duplicate keys in the hash table. This function may be used to
5058 find all of the keys from the hash.
5060 Added user_context arguments to the SilcHashFunction,
5061 SilcHashCompare and SilcHashDestructor to deliver user specified
5064 Added new fuctions silc_hash_table_find[_all]_ext to do
5065 extended lookup with specified hash and compare functions and
5066 specified user contexts.
5068 Added new function silc_hash_table_add_ext to add the key
5069 with specified hash function and user context.
5071 Added new function silc_hash_table_foreach to traverse all
5072 entrys in the hash table. Added SilcHashForeach callback
5075 Added new function silc_hash_table_del_by_context to delete
5076 the entry only if the context associated with the key matches.
5078 Affected files are lib/silcutil/silchashtable.[ch].
5080 * Removed silc_hash_[server/client/channel]_id and added just
5081 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
5082 silc_hash_id_compare to compare two ID's using as the hash table
5083 comparison function. Added also silc_hash_data to hash
5084 binary data and silc_hash_data_compare to compare it.
5086 * Removed silc_idlist_find_client_by_hash as it is not needed
5087 anymore. Affected file silcd/idlist.[ch].
5089 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
5090 to use internally the SilcHashTable. The new ID Cache is a lot
5091 faster than the old one. Some of the ID Cache interface was also
5092 rewritten and obsolete and stupid functions were removed.
5094 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5096 * Added entry_count field to the SilcHashTable to keep the number
5097 of the entries in the table. Implemented the function
5098 silc_hash_table_rehash. Added new function
5099 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
5101 Fixed a minor bug in silc_hash_table_free.
5103 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
5104 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
5105 into the lib/silcutil/silcutil.[ch].
5107 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5109 * Implemented a collision resistant hash table into the
5110 lib/silcutil/silchashtable[ch]. See the header and the source
5111 for the SilcHashTable API.
5113 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5115 * Merged dotconf version 1.0.2 into lib/dotconf.
5117 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5119 * Do not compile anything in lib/silcsim/* if the SIM support
5120 is not enabled. The tree should now compile without problems
5123 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5125 * Compiled the SILC under cygwin. Compiled and tested briefly
5126 without problems. More tests needed. The SIMs didn't compile
5129 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
5131 * Fixed possible crash in silc_get_username in the
5132 lib/silcutil/silcutil.c.
5134 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5136 * Fixed a va_arg in silc/client_ops.c.
5138 * Oops, RC5 routines were named AES and caused some problems
5139 when not using SIM's. Affected file lib/silccrypt/rc5.c.
5141 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5143 * Added new SilcIDIP structure into the lib/silccore/id.h and
5144 replaced the old `ip' fields from all SILC ID's to that type.
5145 This is a step towards IPv6 support.
5147 The silc_id_get_len takes now the ID as an extra argument.
5148 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
5149 both IPv4 and IPv6 based ID's.
5151 The affected files are lib/silccore/id.[ch] and other files
5152 around the tree using these routines.
5154 * Removed the ID length arguments in server from various
5155 silc_server_send_notify_* routines -> they are not needed
5158 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5160 * Fixed memory leak in silc_encode_pem_file in the file
5161 lib/silcutil/silcutil.c.
5163 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5165 * Check minor version as well in the SKE. Affected files are
5166 silcd/protocol.c and lib/silcclient/protocol.c.
5168 * Added --identifier option to the server so that an identifier
5169 can be when creating the public key for the server. Affected
5170 file is silcd/silcd.c.
5172 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
5173 lib/silccrypt/silcpkcs.c.
5175 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5177 * Register default ciphers and stuff when using -C option with
5178 the server. Affected file sildc/silcd.c.
5180 * Put back the servers public key filename format, it is better
5181 than the new one. For now, the client keys are saved with the
5182 new filename format. The affected file silc/client_ops.c.
5184 * Implemented the Cipher API for the rest of the ciphers that
5185 did not implement it or implemented it the wrong way.
5187 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5189 * Register default ciphers and stuff when using the -S option
5190 in the client. Affected file silc/silc.c. Same also when
5191 creating new key pair with -C option.
5193 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5195 * Fixed the silc_verify_public_key client operation function to
5196 save the public keys differently. The fingerprint is now
5197 used as filename and not the hostname. This way also the
5198 client keys are saved uniquely and not with hostnames. The
5199 affected file is silc/client_ops.c.
5201 * Trimmed the silc_hash_fingerprint function to remove extra
5202 whitespaces from the end of the fingerprint. The affected
5203 file is lib/silccrypt/silchash.c.
5207 * Added silc_cipher_register_default function to register all
5208 default ciphers. It can be used when configuration files
5209 does not exist and the application does not want any specific
5210 ciphers in any specific order.
5212 The SilcDList is now used as silc_cipher_list dynamically
5213 allocated cipher list. Removed the static list all together
5214 and now all ciphers must be allocated to the dynamic list.
5215 The silc_cipher_alloc routine was changed to check only the
5218 All silc_cipher_* routines that used to return int returns
5221 The affected files lib/silccrypt/silccrypt.[ch].
5223 * The same thing was done to silc_hash_* as for silc_cipher_*
5224 routines. Affected files lib/silccrypt/silchash.[ch].
5226 * The same thing was done to silc_pkcs_* as for silc_cipher_*
5227 routines. Affected files lib/silccrypt/silcpkcs.[ch].
5228 Added also silc_pkcs_[un]register[_default] functions.
5229 Removed the data_context from the PKCS API.
5231 * Added silc_hmac_register_default function to register default
5232 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
5233 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
5234 to unregister all hmacs at once.
5236 * Register the default ciphers, hash functions, PKCSs and HMACs
5237 if client's configuration file does not exist. The affected
5240 * The client did not load the hash functions from the SIM
5241 modules at all. Added support for this. Affected file is
5242 silc/clientconfig.c.
5244 * When decoding public key with silc_pkcs_public_key_decode, check
5245 the supported algorithm only if PKCS are registered. Affected
5246 file lib/silccrypt/silcpkcs.c. The same was done with the
5247 silc_pkcs_private_key_decode.
5249 * Fixed the SILC List routines to keep the list always in order.
5250 It used to change the list's order when traversing the list but
5251 not it preserves the order. Affected file lib/trq/silclist.h.
5253 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5255 * Added the client library to use the SilcSocketConnection's
5256 reference counter (by silc_socket_dup) to prevent the bug that
5257 the socket object may be freed underneath async operation.
5259 * The name resolv library checking fixes in the configure.in.pre.
5262 * Created new version of the protocol drafts for future
5263 development. The -03 drafts are the ones that will be changed
5264 in the trunk now and the -02 will remain as they are.
5266 * Send list of CUMODE notifys to the router when announcing
5267 the channel users to the router. Affected file silcd/server.c.
5268 If the router receiving channel founder CUMODE for a channel
5269 that already has channel founder it will send CUMODE notify
5270 to the sender to remove the channel founder rights from the
5271 announced client. Affected file silcd/packet_receive.c.
5273 * The CUMODE notify may now use Server ID as well as the entity
5274 who changes the mode. Updated protocool specs.
5276 * Updated INSTALL and README files.
5278 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5280 * New web pages in the http://silc.pspt.fi. The pages was
5285 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5287 * Implemented the [DenyConnectin] config section in the server.
5288 Added silc_server_config_denied_conn to check whether incoming
5289 connection is denied. Affected file silcd/serverconfig.[ch].
5291 * Do not check the ports when checking the incoming configuration
5292 data if the port is 0, meaning any. Affected file is
5293 silcd/serverconfig.c.
5295 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5297 * Fixed buffer overflow in silc_string_compare in the file
5298 lib/silcutil/silcutil.c.
5300 * Fixed double free in silc_server_command_leave in the file
5303 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5305 * Fixed the version checking in the server. Affected file is
5308 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5310 * Fixed the configuration data fetching when accepting new
5311 connections in the server. Affected file silcd/server.c.
5313 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5315 * Added `sender_entry' argument to the function
5316 silc_server_packet_relay_to_channel so that we can check
5317 whether some destination actually belongs to the same route
5318 the sender belongs (ie, we must not resend the packet to the
5319 sender). Affected file silcd/packet_send.[ch].
5321 * Added `servername' field to the SilcClientEntry in the server
5322 to hold the name of the server where client is from. Affected
5323 file is silcd/idlist.h.
5325 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5327 * Moved the channel message encrypting in the router betwen
5328 router connections from silc_server_channel_message to the
5329 silc_server_packet_relay_to_channel since we want to check
5330 whether we have anybody channel before encrypting anything.
5331 Affected files silcd/packet_[receive/send].c.
5333 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5335 * Fixed the [AdminConnection] server config section to support
5336 multiple entries. Affected file silcd/serverconfig.c.
5338 * Added support into the server to check the validity of the
5339 incoming connection before executing any KE or authentication
5342 * The connection configuration is now saved to the KE and
5343 connection auth protocol contexts and not fetched anymore in
5344 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
5346 * The local hosts listenning address and port is also resolved
5347 now when starting the server. We want to have the socket object
5348 to include the real address and port for the listener. Added
5349 new function silc_net_check_local_by_sock into the files
5350 lib/silcutil/silcnet.[ch].
5352 * Fixed a broadcast bug in server -> do not broadcast if we
5355 * Fixed a routing bug. Do not route broadcast packets ever.
5356 Broadcast packets must be processed always and not routed since
5357 they may be destined to some other host than yourself and thus
5358 would get routed without no good reason. Affected file is
5361 * Added function silc_server_config_is_primary_route to check
5362 whether primary router connection has been configured (a router
5363 configuration that we are initiating). If there is not, we
5364 will assume that there is only two routers in the SILC network
5365 and we will use the incoming router connection as our primary
5366 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
5368 * Changed the order of the broadcasting. Broadcast _after_ the
5369 packet has been processed not before. Affected file is
5372 * Fixed a [ClientConnection] parsing bug. The port was never
5373 parsed correctly thus resulting to port 0. Affected file
5374 silcd/serverconfig.c.
5376 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
5377 argument and did not set the broadcast packet flag. Affected
5378 file silcd/packet_send.c. Fixed same bug in the function
5379 silc_server_send_notify as well.
5381 * If we receive NEW_ID packet for our own ID in the server, ignore
5384 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5388 * Removed the nickname from the Private Message Payload.
5389 Updated the code and the protocol specs.
5391 * Updated protocol specs for submitting to the IETF.
5393 * Tweaked the Random Number Generator a bit. Affected file
5394 lib/silccrypt/silcrng.c. Exported a new function
5395 silc_rng_[global]_add_noise which can be used to add more
5398 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5400 * Do not parse packets with different timeout when protocol
5401 is active -> may cause problem with rekey. Affected file
5404 * When server receives signoff notify it must not create
5405 new channel key if the client is on any channels since the
5406 sender of the signoff notify will create it.
5408 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5410 * Added printing of error messages during SKE protocol from the
5411 failure packet sent by server during SKE. Affected file
5414 * Removed the client's failure_callback handling with timeout
5415 and handle it immediately when received.
5417 * The SKE library returned wrong type in SUCCESS and FAILURE
5418 packets. They must be 32 bit MSB not 16 bit MSB.
5420 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5422 * Ok, rewrote the logic of the re-key and now it seems to work.
5423 I tested it on high traffic with frequent re-keys without
5424 problems. Added hmac_receive (and renamed hmac to hmac_send)
5425 in SilcClientConnection in lib/silcclient/client.h and
5426 in SilcIDListData in silcd/idlist.h. Also, removed the
5427 SilcPacketParserContext's cipher and hmac fields as they are
5428 not needed anymore and actually caused some problems when
5429 the ciphers and hmac's changed underneath the packet parser.
5431 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5433 * If re-key protocol is active then process the incoming packets
5434 synchronously since we must assure that icoming packets encrypted
5435 with the old key is processed before the new keys is set to
5436 use. This is true other packets than for REKEY packets.
5437 Affected file silcd/server.c. The same was done to client library
5438 as well, affected file lib/silcclient/client.c.
5440 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5442 * Fixed bug in client and server to accept the force send if
5443 the packet is send from silc_[server/client]_packet_process
5444 function. Otherwise the packets are never delivered, oops.
5446 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5448 * Disable force sending of packets when REKEY protocol is active.
5449 We must assure that no packet is sent directly when rekey is
5450 performed. All packets must be sent through packet queue.
5451 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
5452 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
5453 function is silc_[server/client]_packet_send_real to check
5456 * Replaced the SIM paths from example config files to
5457 /usr/local/modules. Also, make install creates now
5458 /usr/local/silc/logs directory to hold all the SILC server
5461 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5463 * Made the configure.in.pre work on Solaris. Patch by salo.
5465 * Made all ciphers compatible with non-x86 machines. Defined
5466 CBC mode macros into lib/silccrypt/ciphers_def.h.
5468 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5470 * Fixed the make install.
5472 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5474 * When MAC computation fails the silc_packet_decrypt returned 0
5475 even though it was supposed to return -1. Fixed this. The
5476 affected file is lib/silccore/silcpacket.c.
5478 * Do not replace the config files in /etc/silc (in make install)
5479 if they already exist. Affected file ./Makefile.am.
5481 * Do not send re-key packets immediately but through packet queue.
5482 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
5484 * Changed silc_net_check_host_by_sock to return FALSE if the
5485 IP/DNS could not be resolved. Though, it returns the IP address
5486 now even if it could not resolve it (but returns also FALSE).
5487 Affected file lib/silcutil/silcnet.[ch].
5489 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5491 * Added silc_pkcs_decode_identifier to decode the public key's
5492 identifier. Affected file lib/silccrypt/silpkcs.[ch].
5493 Added also silc_pkcs_free_identifier. Added also new context
5494 SilcPublicKeyIdentifier.
5496 * Added -S option to the silc client. It is used to dump the
5497 contents of the specified public key file.
5499 * Changed the PKCS api to return the public key length when
5500 setting the public key.
5502 * Fixed a fatal bug in the public and private key file loading.
5503 Affected file lib/silccrypt/silcpkcs.c.
5505 * Execute the packet parsing for client with zero (0) timeout
5506 if the protocol is active. Affected file silcd/server.c.
5508 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5510 * Made the key generation options to the silcd program. Added
5511 -C option, equivalent to client's option.
5513 * Added new [ServerKeys] config section to the server. It
5514 configures the server's public and private key.
5516 * Defined generic Public Key Payload into the protocol
5517 specification to send specific type of public keys and
5520 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
5521 public key or certificate.
5523 * Implemented the GETKEY command to the server and to the
5524 client library and on user interface.
5526 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5528 * Made preliminary `make install' work.
5530 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5532 * Added SilcServerRekey context into silcd/idlist.h.
5534 * Added the PFS support as defined in the specification to the
5535 SKE protocol. Affected files lib/silcske/*.c.
5537 * Added `ske_group' field to the SilcServerRekey context to hold
5538 the number of the SKE group that is used with PFS in re-key.
5539 Affected file silcd/idlist.h.
5541 * Added PFS re-key support to the server. Affected file is
5544 * Added silc_protocol_cancel to cancel execution of the next
5545 state of the protocol. Affected file is
5546 lib/silccore/silcprotocol.[ch].
5548 * Added the re-key support with and without PFS to the client
5549 library. Re-key is performed once in an hour, by default.
5551 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
5552 Added silc_client_rekey_callback and silc_client_rekey_final.
5553 Affected files are lib/silcclient/protocol.[ch] and
5554 lib/silcclient/client.[ch].
5556 * Removed the `hmac_key' and `hmac_key_len' fields from the
5557 SilcClientConnection structure; not needed. Affected file is
5558 lib/silcclient/client.h.
5562 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5564 * Do not ask whether user wants to use the negotiated private key
5565 for private messages, just use it. Affected file is
5566 silc/local_command.c.
5568 * Added `send_enc_key' and `enc_key_len' fields to the
5569 SilcIDListData structure since they are needed in the re-key
5570 phase. Affected file is silcd/idlist.[ch].
5572 * Implemented the simple re-key protocol into the server.
5573 Affected files silcd/server.c and silcd/protocol.[ch]. The
5574 re-key will be performed once in an hour, by default.
5576 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
5577 Added silc_server_rekey, silc_server_rekey_callback and
5578 silc_server_rekey_final.
5580 * Removed Tunneled flag from the protocol. Updated the code
5581 and the specifications.
5583 * Adde `pfs' field to the SilcIDListData to indicate whether
5584 the PFS is to be performed in the re-key. Affected file is
5587 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5589 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
5590 int64 of at least the xintXX size. If void * is less that 4
5591 bytes uint32 * will be used. Defined bool as boolean.
5593 * Changed _ALL_ unsigned long and unsigned int to uint32,
5594 unsgined short to uint16 in the source tree.
5596 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
5597 not handle clients that has entry->data.registered == FALSE.
5598 They are not in the network anymore. Affected file is
5601 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5603 * Implemented the sending of the SERVER_SIGNOFF notify in the
5604 server. Affected file is silcd/server.c.
5606 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
5607 Added also silc_notify_payload_encode_args into the
5608 lib/silccore/silcnotify.[ch].
5610 * Implemented ther SERVER_SIGNOFF notify handling in the server.
5611 Affected file silcd/packet_receive.c.
5613 * Implemented the SERVER_SIGNOFF notify handling in the client
5614 library. Affected file lib/silcclient/client_notify.c. Also,
5615 implemnted the printing of the SERVER_SIGNOFF info to the
5616 application. Affected file silc/client_ops.c.
5618 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
5619 if the deleting was successful. Affected file silcd/idlist.[ch].
5621 * Added support for public key authentication in the connection
5622 authentication protocol in the client library. Affected file
5623 lib/silcclient/protocol.c.
5625 * Changed the server's silc_idlist_get_clients_by_* interface
5626 to support already allocated array so that new entries may be
5627 added to pre-allocated array. Affected file silcd/idlist.[ch].
5628 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
5629 and command replies.
5631 * All command reply functions in the server now calls the
5632 pending command callback even if error occured. This way the
5633 error will be delivered to the client as well. Affected files
5634 silcd/command.c and silcd/command_reply.c.
5636 * Fixed INFO command to return local server's info if no server
5637 was provided. Affected file lib/silcclient/command.c.
5639 * Removed RESTART command for good. Updated the code and the
5642 * Rewrote parts of the task system. It is a bit simpler now.
5643 Removed unsued task priorities. The affected files are
5644 lib/silcutil/silctask.[ch].
5646 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5648 * Moved the USERS printing from the library to the application.
5649 Affected files lib/silcclient/command.c and silc/client_ops.c.
5651 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5655 * Added channel key re-key support. The re-key is perfomed
5656 only by the router and is done once in an hour. Added `rekey'
5657 field to the SilcChannelEntry in the server. Affected files
5658 silcd/server.c and silcd/idlist.h.
5660 * Added silc_task_unregister_by_context into the file
5661 lib/silcutil/silctask.[ch].
5663 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5665 * Added SILC_UMODE_GONE mode to indicate when the client is not
5666 present in the SILC network. Added also support to the local
5667 command AWAY that will set this mode. Added support of showing
5668 "xxx is gone" in WHOIS command. The USERS command shows the
5669 gone status as well.
5671 * Fixed setting server and router operator privileges in the
5672 server's UMODE command. Affected file silcd/command.c.
5674 * Merged the SKE KE1 and KE2 payloads into one payload. The
5675 new KE payload is equivalent to the old KE2 payload.
5677 Cleaned up the SKE Start Payload parsing. It now uses the
5678 simple buffer unformatting to do the parsing. A lot faster
5681 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
5682 to the SKE that is used to indicate whether both of the SKE
5683 parties should perform authentication. By default only the
5684 responder performs authentication. By setting this flag also
5685 the initiator must do authentication. By default it is unset
5686 since in normal SKE case, client to server connection, only
5687 the responder should do authentication. When doing SKE between
5688 two clients both should perform authentication. Updated the
5689 code and the protocol specs.
5691 * A little fix to IDENTIFY command in the server. Search the
5692 client first by hash not nickname. Affected file is
5695 * Fixed the silc_client_close_connection to support closing
5696 the client to client connections wihtout deleting too much
5697 data. Affected file lib/silcclient/client.c.
5699 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
5700 are received if protocol used to be active but is not anymore
5701 the application would crash due to NULL pointer dereference.
5702 Affected files silcd/server.c and lib/silcclient/client.c.
5704 * Added `hash' field to the SilcClientConnection to include
5705 the hash function negotiated in the SKE protocol.
5707 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
5708 to set the channel founder authentication data. A client can
5709 claim the founder rights later by providing the authentication
5710 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
5711 This way the channel founder can regain the channel founder
5712 privileges even it is left the channel. This works only on
5713 local server and the client must be connected to the same
5714 server to be able to regain the founder rights. Updated the
5715 protocol specs accordingly.
5717 Added support to the CMODE command in the client to set the
5718 founder auth data. Read the README to see how to set it.
5720 Added support to the CUMODE command to claim the founder
5721 rights. Read the README to see how to do it.
5723 Added support for the founder authentication to the Channel
5724 Entry in the server. Affected file silcd/idlist.h.
5726 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
5727 server's CMODE command. Affected file silcd/command.c.
5729 * Added the following new functions into lib/silccore/silcauth.[ch]:
5730 silc_auth_get_method and silc_auth_get_data.
5732 * The server now saves the remote hosts public key to the
5733 SilcIDListData pointer. Affected file silcd/protocol.c.
5735 * The normal server now does not remove the channel entry from
5736 the cache if the founder authentication data is set. It used
5737 to remove it if the founder was the last one on the channel on
5738 the server and left the channel. The auth data is saved and
5739 if the channel is re-joined later the old entry is used with
5740 the old auth data. Affected files silcd/command_reply.c and
5743 * Removed the `pkcs' field from the SilcIDListData structure
5744 in the server; it is not used. Affected file silcd/idlist.h.
5746 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5748 * Fixed packet processing on slow links. Partial packets were
5749 never re-processed because the incoming data buffer was cleared
5750 by the application. Application must not directly clear the
5751 sock->inbuf, the packet processing routines handle it. Fixed
5752 this in client library and in server.
5754 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5756 * Fixed the WHOIS and IDENTIFY send reply function to really
5757 check whether to send list or just one entry. Affected file
5760 * Cleaned up the LEAVE command's channel key distribution. The
5761 affected file silcd/command.c.
5763 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
5764 can enforce the channel mode as well. In that case the ID
5765 includes the ID of the server. The code now enforces the
5766 mode change if the router have different mode than the server.
5768 * The notify client operation with CMODE_CHANGE notify can now
5769 return NULL client_entry pointer if the CMODE was not changed
5770 by client. Application must check for this.
5772 * Added <Server ID> argument to INFO command to support server
5773 info fetching by Server ID.
5775 * Added silc_server_announce_get_channel_users to get assembled
5776 packets of channel users of the specified channel. Affected
5777 file silcd/server.[ch].
5779 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
5780 was freed underneath the ID Cache.
5782 * Re-announce clients when the server received CHANNEL_CHANGE
5783 notify from the router. Affected file silcd/packet_send.c.
5785 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5787 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
5788 crashed since it did not handle the fact that there is no cipher
5789 called "3" and didn't check the error condition. Now fixed.
5791 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
5792 flag. It can be used to send message requests.
5794 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5796 * Implemented the RESTART command in the client.
5798 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
5799 notice type messages. Added notice printing to the user
5802 * The channel keys are not re-generated if the channel's mode
5803 is PRIVKEY, ie private key on the channel exists. Affected
5804 files silcd/server.c and silcd/command.c.
5806 * Fixed a little bug in channel message delivery when channel
5807 private keys are set in the server. Affected file is
5808 silcd/packet_send.c.
5810 * Changed the setting on channel->on_channel = TRUE from the
5811 silc_client_save_channel_key to the JOIN command reply. The
5812 key payload is not received if the private channel key is set.
5813 Affected file lib/silcclient/command_reply.c and the
5814 lib/silcclient/client_channel.c.
5816 * When the CMODE_CHANGE notify is sent and the channel private
5817 key mode is removed the channel key must be re-generated in
5818 other cells as well. Added this support for the router in the
5819 silcd/packet_receive.c.
5821 * Added new local command NOTICE to send notice message on
5822 channel. Affected file silc/local_command.[ch].
5824 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5826 * Added new local command ME to the client. It is used to send
5827 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
5828 some action. Affected file silc/local_command.[ch].
5830 * Changed channel_message and private_message client operations
5831 to deliver the message flags to the application. Added also
5832 the `flags' arguments to the silc_client_send_channel_message
5833 and silc_client_send_private_message functions. Affected file
5836 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5838 * Redefined the Private Message Payload to support private message
5839 keys and to support the new private message flags. Updated
5840 the protocol specs. Flags makes it possible to have for example
5841 CTCP style messages.
5843 * Added new type SilcPrivateMessagePayload and defined an API
5844 for it in the lib/silcclient/silcprivate.[ch].
5846 * Tested private message private keys successfully. Tested the
5847 private message key set, unset and list commands with the new
5850 * Redefined the Channel Message Payload to include the channel
5851 message flags (equal with private message flags) to support
5852 for example CTCP style messages.
5854 * Defined some of the message (for channel and private message)
5855 flags. Updated the protocol specs and added the flags to the
5856 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5858 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5860 * Added SilcKeyAgreementStatus type to the key agreement routines
5861 to indicate the current status and error if one occured.
5862 The status types are defined in the lib/silcclient/silcapi.h.
5864 * Added new local command KEY that is used to set and unset private
5865 keys for channels, set and unset private keys for private messages
5866 with remote clients and to send key agreement requests and
5867 negotiate the key agreement protocol with remote client. The
5868 key agreement is supported only to negotiate private message keys,
5869 it currently cannot be used to negotiate private keys for channels,
5870 as it is not convenient for that purpose.
5872 * Fixed a minor pending callback setting bug in the function
5873 silc_client_get_client_by_id_resolve, now the function works.
5874 Affected file lib/silcclient/idlist.c.
5876 * Added function silc_net_get_local_port to get local bound
5877 port by socket. Added to lib/silcutil/silcnet.[ch].
5879 * Added `sockets' and `sockets_count' fields to the SilcClient
5880 object. They hold the sockets of the listenning sockets in
5881 the client. Listenning sockets may be for example the key
5882 agreement server. Affected file lib/silcclient/client.[ch].
5883 Added functions the silc_client_add_socket and the
5884 silc_client_del_socket. They are exported to the application
5887 * Added ~./silc/clientkeys to support other client's public keys.
5889 * Renamed verify_server_key client operation to verify_public_key
5890 and added one argument to indicate the type of the connection
5891 (server, client etc.).
5893 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5895 * Added silc_server_connection_auth_request to handle the
5896 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5897 silcd/packet_receive.[ch].
5899 * Added silc_server_send_connection_auth_request into the
5900 silcd/packet_send.c to send the connection auth request packet.
5902 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5905 * Fixed the public key authentication in responder side in the
5906 server. The `auth_data' pointer includes the SilcPublicKey
5907 not the path to the public key. Affected file silcd/protocol.c.
5909 * Implemented the public key authentication in the initiator side
5910 in the server. Affected file silcd/protocol.c.
5912 * Removed the [RedirectClient] config section from the server
5913 configuration. Is not needed and I don't want to implement it.
5915 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5917 * Cleaned up the CMODE command in the server. It now works
5918 correctly and supports all the modes defined in the protocol.
5919 Affected file is silcd/command.c.
5921 * Added `hmac_name' field to the SilcChannelEntry in the server
5922 to hold the default HMAC of the channel. It can be set when
5923 creating the channel (with JOIN command). Affected files
5926 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5927 type to indicate the change of the current cipher and hmac
5928 on the channel. Client can safely ignore the <cipher> argument
5929 (if it chooses to do so) since the CHANNEL_KEY packet will
5930 force the channel key change anyway. The <hmac> argument is
5931 important since the client is responsible of setting the new
5932 HMAC and the hmac key into use.
5934 * Fixed the CMODE command in the client library as well.
5936 * Tested CMODE command in router environment successfully.
5938 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5940 * Show the version of the remote client (or server) when connecting
5941 to the server. It is logged to the log file. Affected file
5942 is silcd/protocol.c.
5944 * Fixed the KILLED notify handling in the client library. The
5945 client must be removed from all channels when receiving the
5948 Also, do not remove the client entry when giving the KILL
5949 command but when the KILLED notify is received.
5951 * Removed silc_idlist_find_client_by_nickname from the server.
5952 Not needed anymore. Affected files silcd/idlist.[ch].
5954 * Implemented the CHANNEL_CHANGE notify type handling to the
5955 server. Affected file silcd/server.c.
5959 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5961 * Added silc_server_send_notify_invite to send the INVITE
5962 notify between routers.
5964 * Implemented the INVITE command correctly to the server.
5966 * Implemented the INVITE notify type handling in the server.
5968 * Implemented the INVITE command to the client library and on the
5971 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5973 * Added function silc_server_get_client_resolve to find the
5974 client entry by ID from all ID lists and then resolve it
5975 (using WHOIS) if it cannot be found. Affected file is
5978 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5980 * Implemented the BAN command to the client library.
5982 * The JOIN command in the server now checks the invite list
5985 * Changed the silc_command_reply_payload_encode_va and the
5986 silc_command_payload_encode_va to support that if argument is
5987 NULL it ignores and checks the next argument. Affected file
5988 lib/silccore/silccommand.c.
5990 * Added silc_server_send_notify_ban to send the BAN notify
5991 type between routers.
5993 * Chaned the silc_notify_payload_encode to support that if
5994 argument is NULL it ignores and checks the next argument.
5995 Affected file lib/silccore/silcnotify.c.
5997 * Tested ban lists in router environment successfully.
5999 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6001 * Implemented BAN command to the server, in silcd/command.[ch].
6003 * Removed the BAN and INVITE_LIST modes from the CMODE command
6006 * Added function silc_string_match to regex match two strings.
6007 Affected files lib/silcutil/silcutil.[ch].
6009 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6011 * Redefined parts of the SilcChannelEntry in the server to support
6012 the new ban and invite lists.
6014 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6016 * Redefined the INVITE command. The same command can be used to
6017 invite individuals to the channel but also to manage the invite
6018 list of the channel (to add to and remove from the invite list).
6019 Updated the protocol specs.
6021 * Added new command SILC_COMMAND_BAN that can be used to manage
6022 the ban list of the channel. Updated the protocol specs.
6024 * Removed the channel modes: the SILC_CMODE_BAN and the
6025 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
6026 in the CMODE command. The equivalent features are now available
6027 using INVITE and BAN commands. Updated the protocol specs.
6029 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
6030 in the network about change in the current ban list. The notify
6031 type is not used by the client.
6033 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
6034 support the invite lists.
6036 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6038 * Added new function silc_string_regexify that converts string
6039 including wildcard characters into regex string that can
6040 be used by the GNU regex library. Added into the file
6041 lib/silcutil/silcutil.[ch].
6043 Added silc_string_regex_combine to combine to regex strings
6044 into one so that they can be used as one regex string by
6045 the GNU regex library. Added into the file
6046 lib/silcutil/silcutil.[ch].
6048 Added silc_string_regex_match to match two strings. It returns
6049 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
6051 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6053 * Imported GNU regex to the soruce tree into lib/contrib.
6054 Fixed some compiler warning from the regex.c.
6056 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6058 * Fixed MOTD command in the server to work in router environment.
6060 * Fixed the MOTD command in the client library to support
6061 the server argument in the command.
6063 * Added `nickname_len' argument to the silc_idlist_add_client
6064 in the server, as the `nickname' argument may be binary data
6067 * Added silc_idlist_get_channels to return all channels from
6070 * Implemented LIST command to the server. Affected file is
6073 * Implemented the LIST command to the client library and on the
6076 * Added [<user count>] argument to the LIST command reply.
6077 With private channels the user count is not shown.
6079 * Updated TODO and README.
6081 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6083 * The client entry's data.registered must be TRUE even with
6084 global client entry on global client list. The data.registered
6085 is used to check whether the client is anymore in the network,
6086 for example with WHOWAS command so it must be valid.
6088 * Fixed the WHOWAS command in the server. It now actually works
6089 in router environment. Added function into silcd/command_reply.c
6090 silc_server_command_reply_whowas_save.
6092 * Added silc_idlist_purge function to the silcd/idlist.c
6093 to periodically purge the ID Cache.
6095 * Fixed INFO command in the server. It works now in router
6096 environment. Added <server name> argument to the INFO command
6097 reply. Updated the protocol specs.
6099 * Fixed minor bug in silc_idcache_purge to not purge if the
6100 expire value is zero.
6102 * Fixed various bugs in WHOIS and IDENTIFY command handling as
6103 they were buggy because of the WHOWAS information.
6105 * Fixed local command MSG to handle the async resolving of
6106 the remote client properly. It used to fail the first MSG.
6107 Affected file silc/local_command.c.
6109 * Added `data_len' field to SilcIDCache context.
6111 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6113 * Update TODO. Todo in commands in the server.
6115 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6117 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
6118 used by routers as broadcast packet to inform other routers
6119 about the changed user mode.
6121 Implemented the notify handling in the server. Affected file is
6122 silcd/packet_receive.c. Added the function
6123 silc_server_send_notify_umode to the silcd/packet_send.[ch].
6125 * Added new generic Channel Payload and deprecated the New Channel
6126 Payload. The New Channel Payload is now the generic Channel
6129 * Added new argument `mode' to the silc_server_send_new_channel
6130 as it is required in the Channel Payload now.
6132 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
6133 and created a new and real SilChannelPayload to represent the
6134 new generic Channel Payload. Implemented the encode/decode
6135 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
6137 * Added silc_server_get_client_channel_list to return the list
6138 of channels the client has joined for WHOIS command reply.
6139 Affected file silcd/server.[ch].
6141 * Implemented the channel list sending in the WHOIS command reply
6142 in server and in the client.
6144 Implemented the channel list displaying on the user interface
6145 as well. Affected file silc/client_ops.c.
6147 * Added silc_channel_payload_parse_list to parse list of Channel
6148 Payloads. It returns SilcDList list of SilcChannelPayloads.
6149 Client for example can use this function to parse the list of
6150 channels it receives in the WHOIS command reply. The caller
6151 must free the list by calling silc_channel_payload_list_free.
6152 Affected files lib/silccore/silcchannel.[ch].
6154 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6156 * Added one new argument <user mode> to the WHOIS command reply
6157 to return the mode of the user in SILC. Updated the protocol
6160 Implemented it to the server and client.
6162 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6164 * Fixed the mode printing on the user interface on joining.
6165 Affected file silc/client_ops.c.
6167 * Implemented the UMODE command and user modes in general to the
6168 client library and to the user interface.
6170 * Implemented the UMODE command to the server.
6172 * The server now sends UNKNOWN_COMMAND error status if client sends
6173 unknown command. Affected file silcd/command.c.
6175 * All server commands now handle the command identifier the right
6176 way when sending the command reply to the client. The client can
6177 use to identify the command replies with the identifier.
6179 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6181 * Added silc_server_get_client_route to resolve the route to
6182 the client indicated by the client ID. Affected file is
6185 * Added silc_server_relay_packet as general function to relay
6186 packet to arbitrary destination. This deprecates functions
6187 like _send_private_message_key, _relay_notify etc. Affected
6188 file is silcd/packet_send.[ch].
6190 Removed silc_server_send_key_agreement,
6191 silc_server_send_private_message_key and
6192 silc_server_packet_relay_notify functions from the file
6193 silcd/packet_send.[ch].
6197 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
6198 server. Affected file silcd/packet_receive.[ch].
6200 * Implemented the KILL command to the client. Implemented the
6201 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
6202 Affected files lib/silcclient/command[_reply].c and
6203 lib/silcclient/client_notify.c. Implemented the KILL notify
6204 printing in the user inteface.
6206 * Fixed a lot silc_parse_nick memory leaks from the client
6207 library in the file lib/silcclient/command.c.
6209 * Changed the silc_server_send_notify_on_channels's `sender'
6210 argument from SilcSocketConnection to SilcClientEntry to
6211 check the sender as entry and not as connection object and not
6212 to send to the client provided as argument. The affected file
6213 is silcd/packet_send.[ch].
6215 * The notify packets that are destined directly to the client used
6216 to not to be processed by the server. Now changed that and the
6217 server processes all notify packets. After relaying the packet
6218 to the client the notify packet is processed in the server.
6220 * The silc_server_free_client_data now checks whether there is
6221 pending outgoing traffic for the client and purges the data to
6222 the network before removing the client entry.
6224 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6226 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
6227 an client is killed from the SILC Network. Updated the protocol
6230 Added new function silc_server_send_notify_killed to the
6231 silcd/packet_send.[ch].
6233 * Added function silc_server_packet_relay_notify to relay notify
6234 packets that are destined directly to a client. In this case
6235 the server does not process the notify packets but merely relays
6236 it to the client. Affected file silcd/packet_send.[ch].
6238 Added also silc_server_packet_process_relay_notify to check
6239 whereto relay the notify. Affected file is
6240 silcd/packet_receive.[ch].
6242 * Implemented the KILL command to the server.
6246 * Added the backup schema desgined last fall to the protocol
6247 specs for everyone to see. The specification is in the
6248 *-spec-xx.txt draft and the packet type definitions for the
6249 backup routers is in *-pp-xx.txt draft. Thusly, added also
6250 new packet type SILC_PACKET_CELL_ROUTERS.
6252 * A big security problem in the implementation discovered. The
6253 signoff of an client did not cause new channel key generation
6254 which it of course should've done. The channel keys must be
6255 always re-generated when client leaves (or signoffs) the channel.
6256 The silc_server_remove_from_channels funtion now handles
6257 the channel key re-generation.
6259 * Added `sender' argument to the silc_server_send_notify_on_channels
6260 to not to send the client provided as argument. Affected file
6261 silcd/packet_send.[ch].
6263 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6265 * Implemented OPER and SILCOPER commands into the server and
6268 * Added silc_auth_verify and silc_auth_verify_data to verify
6269 the authentication directly from the authentication payload.
6270 It supports verifying both passphrase and public key based
6271 authentication. Affected file lib/silccore/silcauth.[ch].
6273 * Added `hash' field to the SilcIDListData structure. It is the
6274 hash negotiated in the SKE protocol. Affected file is
6277 * Slight redesigning of the SilcAuthPayload handling routines.
6278 Do not send SilcPKCS but SilcPublicKey as argument.
6280 * Implemented the public key authentication support to the
6281 serverconfig. The public key is loaded from the provided path
6282 and saved as authentication data to void * pointer. Thus,
6283 changed the unsigned char *auth_data to void *auth_data;
6285 * Fixed SHUTDOWN command to send the reply before the server
6286 is shutdown. :) Affected file silcd/command.c.
6288 * Fixed fatal bug in CONNECT command. The hostname was invalid
6289 memory and server crashed. Affected file silcd/command.c.
6291 * Fixed fatal bug in CLOSE command. The server_entry became
6292 invalid but was referenced later in the command. Affected file
6295 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6297 * Fixed fatal bug in failure packet handling. Server ignored
6298 the failure and thus crashed when it came.
6302 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6304 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
6305 that the command may be executed only once in (about) 2 seconds.
6306 The old SILC_CF_LAG flag is same but allows command bursts up
6307 to five before limiting.
6309 Added the support for CF_LAG and CF_LAG_STRICT flags to the
6310 server code. Various commands now includes the CF_LAG_STRICT
6311 flag to disallow any kind of miss-use of the command.
6313 * Fixed the silc_buffer_unformat to not to allocate any data
6314 if the length of the data is zero. It used to allocate the
6315 length + 1. Affected file lib/silcutil/silcbuffmt.c.
6317 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6319 * Changed the format of AdminConnection configuration section
6320 in the server. Added username of the admin to the format.
6321 Affected files silcd/serverconfig.[ch].
6323 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
6324 to return admin configuration data by host, username and/or
6327 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6329 * Implemented WHOWAS command to the server. Added the functions:
6331 silc_server_command_whowas_parse,
6332 silc_server_command_whowas_send_reply,
6333 silc_server_command_whowas_from_client and
6334 silc_server_command_whowas_from_server
6336 * Added <Client ID> argument to the WHOWAS command reply. Updated
6337 the protocol specs accordingly.
6339 * Implemented WHOWAS command and command_reply to the client
6342 Implemented the WHOWAS printing on the user interface.
6344 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6346 * Added new argument to the WHOWAS command reply, the real name.
6347 It is an optional argument. Updated the protocol specs.
6349 * Added SilcIDCacheDestructor callback that is registered when
6350 the SilcIDCache is allocated. The callback is called when
6351 an cache entry in the ID Cache expires, or is purged from the
6352 cache. Added into lib/silccore/idcache.[ch].
6354 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
6355 to destruct the client entries when the cache entry expires.
6356 Other ID Cache's in server and in the client library ignores
6359 * If the ID Cache entry's `expire' field is zero then the entry
6360 never expires. Added boolean `expire' argument to the
6361 silc_idcache_add function in the lib/silccore/idcache.[ch].
6362 If it is TRUE the default expiry value is used.
6364 * Added silc_server_free_client_data_timeout that is registered
6365 when client disconnects. By default for 5 minutes we preserve
6366 the client entry for history - for WHOWAS command.
6368 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6370 * Added support to the server to enforce that commands are not
6371 executed more than once in 2 seconds. If server receives
6372 commands from client more frequently, timeout is registered
6373 to process the commands. Affected file silcd/command.c.
6374 Added new function silc_server_command_process_timeout.
6376 * Changed NICK_NOTIFY handling in client library to check that
6377 if the client's nickname was changed, so there is no need to
6378 resolve anything from the server.
6380 * Removed error printing from the WHOIS and IDENTIFY commands.
6381 If error occurs then it is ignored silently in the client library.
6382 The application, however, may map the received error to
6383 human readable error string. The application currently maps
6384 the NO_SUCH_NICKNAME error to string.
6386 * Made the command status message public to the application. Moved
6387 them from lib/silcclient/command_reply.c to
6388 lib/silcclient/command_reply.h. The application can map the
6389 received command status to the string with the
6390 silc_client_command_status_message function.
6392 * Added check to the server to check that client's ID is same
6393 as the Source ID in the packet the client sent. They must
6396 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6398 * Added dist-bzip hook to the Makefile.am to make bzip2
6399 compressed distributions.
6401 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6403 * Server now enforces the maximum length for the nickname and
6404 the channel as protocol specification dictates. 128 bytes for
6405 nickname and 256 bytes for channel name.
6407 * Moved the WHOIS printing to the application. The client libary
6408 does not print out the WHOIS information anymore, the application
6409 must do it. Renamed silc_client_command_reply_whois_print to
6410 the silc_client_command_reply_whois_save.
6412 The client's idle time is also sent to the application now, and
6413 the idle is shown on screen.
6415 * Added silc_client_command_reply_identify_save to save the
6416 received IDENTIFY entries.
6418 * Do not check for channel private keys in message sending and
6419 reception if the channel does not have the PRIVKEY mode set.
6420 Affected file lib/silclient/client_channel.c.
6422 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6424 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
6425 just surfaced after chaning the JOIN procedure.
6427 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6429 * Added silc_client_get_clients_by_list to get client entries
6430 from Client ID list, that is returned for example by JOIN
6431 and USERS command replies. The application should use this
6432 function for example when JOIN command reply is received to
6433 resolve the clients already on the channel (library does not
6434 do that anymore as USERS command reply is not used in the JOIN
6435 procedure anymore). Affected files lib/silcclient/silcapi.h and
6436 lib/silcclient/idlist.c.
6438 * JOIN command reply and USERS command reply returns now SilcBuffer
6439 pointers instead of unsigned char pointers when returning
6440 the client list and mode list.
6442 * Added <Client ID> argument to the JOIN command reply, mainly
6443 for the server to identify for which client the command was
6444 originally sent. Updated protocol specs accordingly.
6446 * Added SilcDlist private_key pointer to the SilcChannelEntry
6447 in the client to support the channel private keys. Affected
6448 file is lib/silcclient/idlist.h.
6450 * Added SilcChannelPrivateKey argument to the function
6451 silc_client_send_channel_message so that application can choose
6452 to use specific private ke if it wants to. If it is not provided,
6453 the normal channel key is used, unless private keys are set.
6454 In this case the first (key that was added first) is used
6455 as the encryption key.
6457 * Implemented the support for channel private key handling.
6458 Implemented the following functions:
6460 silc_client_add_channel_private_key,
6461 silc_client_del_channel_private_keys,
6462 silc_client_del_channel_private_key,
6463 silc_client_list_channel_private_keys and
6464 silc_client_free_channel_private_keys
6466 Affected file lib/silcclient/client_channel.c.
6468 * Added the support for the private keys in the channel message
6469 sending and encryption and in the message reception and
6470 decryption. Affected funtions are
6471 silc_client_send_channel_message and silc_client_channel_message.
6473 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6475 * Added SKE's key verify callback to the client library's
6476 KE protocol context. Affected files lib/silcclient/protocol.[ch].
6478 * Removed the statement that server (or router) must send USERS
6479 command reply when joining to the channel so that the client
6480 knows who are on the channel. Instead, the client list and
6481 client's mode list is now sent in the JOIN command reply to the
6482 client who joined channel. This is better solution.
6484 * Added function silc_server_get_users_on_channel and function
6485 silc_server_save_users_on_channel to the silcd/server.[ch].
6487 * Removed function silc_server_command_send_users from the
6490 * Do not show topic on the client library anymore. The topic is
6491 sent in the command reply notify to the application and the
6492 application must show the topic now.
6494 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6496 * Added client searching by nickname hash into the IDENTIFY and
6497 WHOIS commands in the server as they were clearly missing from
6498 them. Affected file is silcd/command.c.
6500 * Fixed a bug in private message receiving in the client library.
6501 The remote ID was freed and it wasn't supposed, now it is
6504 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6506 * Minor fix to the channel payload; allocate the data area, as it
6507 needs to be of specific length.
6509 * If the key agreement port is zero then the operating
6510 system will define the bound port. Affected files are
6511 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
6513 * Added new function silc_channel_payload_decrypt into the file
6514 lib/silccore/silcchannel.[ch].
6516 * Moved the channel message etc, check from silc_packet_decrypt
6517 to applications. The library calls now a generic
6518 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
6519 when the packet is either normal or special. This was done to
6520 allow more wide range of checking that was not allowed when
6521 the code was in library. Now applications can do virtually any
6522 checks to the packet and return to the library the decision how
6523 the packet should be processed. Affected files are
6524 lib/silccore/silcpacket.[ch].
6526 Added silc_server_packet_decrypt_check to the server and
6527 silc_client_packet_decrypt_check to the client library.
6529 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
6530 to send with specified source and destination information.
6532 * Channel message delivery between routers was broken after the
6533 channel key distribution was fixed earlier. The channel key
6534 was used be to distributed to other routers as well which is not
6535 allowed by the protocol. Now this is fixed and channel keys
6536 really are cell specific and the channel message delivery between
6537 routers comply with the protocol specification.
6539 * Fixed various commands in server to check also the global list
6540 for the channel entry and not just the local list. The affected
6541 file silcd/command.c.
6543 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6545 * Added assert()s to buffer formatting and unformatting routines
6546 to assert (if --enable-debug) when error occurs. Affected
6547 file: lib/silcutil/silcbuffmt.c.
6549 * Changed to auto-reconnect to check whether the remote host is
6550 router and register the re-connect timeout if it is. It used
6551 to check that whether we are normal server, but router must do
6552 auto-reconnect with another router as well. Affected file
6555 * Removed the [<key len>] option from CMODE command as the cipher
6556 name decides the key length, nowadays. See the defined ciphers
6557 from the protocol specification.
6559 * Added [<hmac>] option to the CMODE command to define the HMAC
6560 for the channel. Added SILC_CMODE_HMAC channel mode.
6562 * Added [<hmac>] option for the JOIN command so that user can
6563 select which HMAC is used to compute the MACs of the channel
6566 * Added Hmac field to the Channel Message Payload. The integrity
6567 of plaintext channel messages are now protected by computing
6568 MAC of the message and attaching the MAC to the payload. The
6569 MAC is encrypted. Now, it is clear that this causes some
6570 overhead to the size of the packet but rationale for this is that
6571 now the receiver can verify whether the channel message decrypted
6572 correctly and also when private keys are set for the channel the
6573 receiver can decrypt the packet with several keys and check from
6574 the MAC which key decrypted the message correctly.
6576 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
6577 lib/silccrypt/silccipher.[ch].
6579 * Added silc_hash_len to return the digest length into the
6580 lib/silcrypt/silchash.[ch].
6582 * Rewrote parts of Silc Channel Payload interface in the
6583 lib/silccore/silcchannel.[ch]. The encode function now also
6584 encrypts the packet and parse function decrypts it.
6586 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6588 * Fixed a minor formatting bug in the SKE's key material processing.
6589 It actually might have processed the keys wrong way resulting
6592 * Redefined the mandatory HMAC algorithms and added new algorithms.
6593 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
6594 and hmac-md5 truncated to 96 bits. The mandatory is now
6595 hmac-sha1-96. Rest are optional (including the one that used
6596 to be mandatory). Rationale for this is that the truncated HMAC
6597 length is sufficient from security point of view and can actually
6598 make the attack against the HMAC harder. Also, the truncated
6599 HMAC causes less overhead to the packets. See the RFC2104 for
6602 * Added new [hmac] configuration section. The SKE used to use
6603 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
6604 is of course wrong. The official names that must be proposed in
6605 the SKE are the ones defined in the protocol specification
6606 (hmac-sha1-96 for example). The user can configure any hmac
6607 using any hash function configured in the [hash] section. At
6608 least, the mandatory must be configured.
6610 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
6612 * Added HMAC list to the SKE proposal list. It has now both
6613 hash algorithm list and HMAC list. This makes the protocol
6614 incompatible with previous versions. The SKE now seems to work
6615 the way it is supposed to work, for the first time actually.
6617 * Defined plain Hash algorithms to the protocol specification.
6620 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6622 * Implemented support for key agreement packets into the server.
6623 Added functions silc_server_key_agreement and
6624 silc_server_send_key_agreement. Other than these functions,
6625 server has nothing to do with this packet.
6627 * Added support for private message key packets into the server.
6628 Added functions silc_server_private_message_key and
6629 silc_server_send_private_message_key.
6633 * Changed the silc_[client|server]_protocol_ke_set_keys to be
6634 called in the protocol's final callback instead in the END
6635 protocol state. This makes a little more sense and in the same
6636 time in client we can use the same protocol routines for normal
6637 key exchange and to key agreement packet handling as well.
6639 * Added to both client's and server's KE protocol context the
6640 SilcSKEKeyMaterial pointer to save the key material. We will
6641 bring the key material to the protocol's final callback by doing
6642 this. The final callback must free the key material.
6644 * Added SKE's packet_send callback into client's KE protocol
6645 context so that the caller can choose what packet sending function
6646 is used. This way we can use different packet sending when
6647 doing normal SKE when doing key agreement packet handling (in
6648 the key agreement packet handling we do not want to encrypt
6651 * Implemented the responder side of the key agreement routines
6652 in the client. The client can now bind to specified port and
6653 accept incoming key negotiation. The key material is passed
6654 to the application after the protocol is over.
6656 * Implemented the processing of incoming Key Agreement packet
6657 in the client. Added function silc_client_key_agreement to
6660 * Implemented the intiator side of the key agreement routines
6661 in the client. The client can now initiate key agreement with
6662 another remote client. The key material is passed to the
6663 application after the protocol is over.
6665 * Created client_keyagr.c to include all the key agreement
6668 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
6669 SILC_TASK_CALLBACK except that it is not static.
6671 * Created client_notify.c and moved the Notify packet handling
6672 from the client.[ch] into that file.
6674 * Created client_prvmsg.c and moved all private message and
6675 private message key routines from the client.[ch] into that file.
6677 * Create client_channel.c and moved all channel message and
6678 channel private key routines from the client.[ch] into that file.
6680 * Changed silc_client_get_client_by_id_resolve to resolve with
6681 WHOIS command instead of IDENTIFY command, in the file
6682 lib/silclient/idlist.c.
6684 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6686 * Implemented the SKE's responder side to the Client library.
6688 * When FAILURE is received to the protocol do not trust it
6689 blindly. Register a timeout to wait whether the remote closes
6690 the connection as it should do it, only after that process the
6691 actual failure. This was changed to both client and server.
6693 * Added client_internal.h to include some of the structures
6694 there instead of client.h in lib/silcclient/.
6696 * Added function silc_task_unregister_by_callback to unregister
6697 timeouts by the callback function.
6699 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6701 * Some "Incomplete WHOIS info" errors has been appearing on the
6702 log files. Took away the entry->userinfo check from WHOIS
6703 reply sending. The entry->userinfo is now " " if client did not
6704 provide one. I thought this was fixed earlier but something
6705 is wrong still. Let's see if the error still appears.
6707 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6709 * Fixed a minor bug in the login when the channel key is
6710 re-generated in the server. It used to generate the key in
6711 wrong order and thus caused problems in the channel traffic.
6713 * Fixed a minor bug in channel key distsribution after
6714 KICK command. The key was not sent to the router even though
6717 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6719 * Added silc_ske_process_key_material_data as generic routine
6720 to process any key material as the SILC protocol dictates. The
6721 function is used by the actual SKE library but can be used by
6722 applications as well. This relates to the private message keys
6723 and the channel private keys since they must be processed the
6724 same way the normal SILC session keys. The protocol dictates
6725 this. Affected files: lib/silcske/silcske.[ch].
6727 Added also silc_ske_free_key_material to free the
6728 SilcSKEKeyMaterial structure.
6730 * Defined silc_cipher_set_key function to set the key for
6731 cipher without using the object's method function. The affected
6732 files: lib/silccrypt/silccipher.[ch].
6734 * Implemented silc silc_client_add_private_message_key,
6735 silc_client_add_private_message_key_ske,
6736 silc_client_del_private_message_key,
6737 silc_client_list_private_message_keys and
6738 silc_client_free_private_message_keys functions in the
6741 Added functions silc_client_send_private_message_key to send
6742 the Private Message Key payload and silc_client_private_message_key
6743 to handle incoming Private Message Key payload.
6745 * Added Cipher field to the Private Message Key payload to set
6746 the cipher to be used. If ignored, the default cipher defined
6747 in the SILC protocol (aes-256-cbc) is used.
6749 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6751 * Removed lib/silcclient/ops.h file.
6753 Redefined parts of the SILC Client Library API. Created new
6754 file silcapi.h that deprecates the ops.h file and defines the
6755 published Client Library API. Defined also private message key
6756 API and channel private key API into the file.
6758 This is the file that the application must include from the
6759 SILC Client Library. Other files need not be included by
6760 the application anymore.
6762 * Added new key_agreement client operation callback and also
6763 defined the Key Agreement library API for the application.
6765 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6767 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
6768 is used by clients to request key negotiation between another
6769 client in the SILC network. If the negotiation is started it
6770 is performed using the SKE protocol. The result of the
6771 negotiation, the secret key material, can be used for example
6772 as private message key.
6774 Implemented the Key Agreement payload into the files
6775 lib/silccore/silauth.[ch].
6777 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6779 * Redefined ciphers for the SILC protocol. Added some new ciphers
6780 and defined the key lengths for the algorithms. Changed the
6781 code accordingly. The default key length is now 256 bits.
6783 * Fixed SKE key distribution function silc_ske_process_key_material
6784 when the key length is more than 128 bits. The default key
6785 length in SILC is now 256 bits.
6787 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
6788 to indicate unsupported algorithm.
6790 * Renamed rijndael.c to aes.c and all functions as well.
6792 * Fixed a long standing channel key setting bug in client library.
6793 Weird that it has never surfaced before.
6795 * Fixed bug in channel deletion. If the entire channel is removed
6796 then it must also delete the references of the channel entry
6797 from the client's channel list as the client's channel entry and
6798 the channel's client entry share same memory.
6800 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6802 * Implemented CONNECT and SHUTDOWN commands in the client.
6804 * Implemented CLOSE command to the client.
6806 * Added the function silc_idlist_find_server_by_name into the
6807 files silcd/idlist.[ch].
6809 Added the function silc_idlist_find_server_by_conn into the
6810 files silcd/idlist.[ch].
6812 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6814 * DIE command was renamed to SHUTDOWN. Updated the both code
6817 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
6818 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
6820 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
6823 * Added function silc_server_create_connection function to create
6824 connection to remote router. My server implementation actually
6825 does not allow router to connect to normal server (it expects
6826 that normal server always initiates the connection to the router)
6827 so the CONNECT command is only good for connecting to another
6830 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6832 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
6833 or some other client was kicked from the channel.
6835 Implemented the handling of the notify type to both client
6838 Implemented silc_server_send_notify_kicked to send the KICKED
6839 notify. It is used to send it to the server's primary router.
6841 * Implemented the KICK command into server and client.
6843 * Added `query' argument to the silc_idlist_get_client function
6844 to indicate whether to query the client from server or not if
6847 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
6848 to indicate that the client is not channel founder.
6852 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6854 * Removed the rng context from SilcPacketContext structure and
6855 changed that the packet routine uses the Global RNG API.
6857 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6859 * Added support for quit message that client can "leave" on the
6860 channel when it quits the SILC. It is ditributed inside the
6861 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6863 Added silc_server_free_client_data that will take the
6864 signoff message as argument.
6866 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6868 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6870 * Updated parts of the protocol specification to keep it up
6873 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6875 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6876 payloads in one packet.
6878 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6879 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6880 use now the new List flag.
6882 * Also deprecated the following packet types: REPLACE_ID,
6883 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6885 * Added list support for Notify packet in server.
6887 * Added silc_server_send_notify_channel_change to send the
6888 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6889 the silc_server_send_replace_id.
6891 * Added silc_server_send_notify_nick_change to send the
6892 NICK_CHANGE notify type. Deprecates the function
6893 silc_server_send_replace_id.
6895 * Added silc_server_send_notify_join to send the JOIN notify type.
6896 Deprecates the function silc_server_send_new_channel_user.
6898 * Added silc_server_send_notify_leave to send LEAVE notify type.
6899 Deprecates the function silc_server_send_remove_channel_user.
6901 * Added silc_server_send_notify_cmode and
6902 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6903 types. Deprecates the silc_server_send_set_mode function.
6905 * Added SERVER_SIGNOFF notify type to indicate that server has
6906 quit. This means that all clients on the channel from that
6907 server will drop. This can be also used when netsplit happens.
6909 Deprecated REMOVE_ID packet type since it is not needed anymore
6912 Added silc_server_send_notify_server_signoff to send the
6913 SERVER_SIGNOFF notify type. Deprecates the function
6914 silc_server_send_remove_id.
6916 Added also silc_server_send_notify_signoff to send the
6917 SIGNOFF notify type.
6919 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6920 SILC protocol from this day on. Changed the protocol
6921 specification as well.
6923 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6924 notify type. It is used between routers to notify about
6925 topic changes on a channel.
6927 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6930 * Partly updated the protocol specification to comply with the
6931 changes now made. It is still though a bit outdated.
6933 * The JOIN notify type now takes one extra argument <Channel ID>.
6934 The packet used to be destined to the channel but now the
6935 JOIN type may be sent as list thus it is impossible to
6936 destine it to any specific channel. By adding this argument
6937 it is again possible.
6939 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6941 * Added CREDITS file. The CHANGES and CREDITS file will appear
6942 in the distribution as well.
6944 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6946 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6947 types in the server's silcd/packet_receive.c.
6949 * Implemented CMODE and CUMODE to work in router environment.
6951 * Fixed minor encoding and decoding buglet from the
6952 lib/silccore/silcmode.c.
6954 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6957 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6959 * Changed all SilcConfigServer* and silc_config_server* to
6960 SilcServerConfig* and silc_server_config*, respectively.
6963 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6965 * Associated the ID (client or server ID) to the Authentication
6966 Payload to avoid any possibility of forging. Updated the
6967 protocol specification and the code accordingly.
6969 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6971 * The RSA key length is now save to the RsaKey context in the
6972 key generation process in lib/silccrypt/rsa.c. The key length
6973 is now used to figure out the maximum size of the block allowed
6974 to be encrypted/signed.
6976 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6977 is equivalent to the silc_mp_mp2bin but does not allocate any
6980 * Changed silc_mp_mp2bin API to take length argument. If it is
6981 non-zero then the buffer is allocated that large. If zero, then
6982 the size is approximated using silc_mp_sizeinbase, which however
6985 * Created Global RNG API which is global RNG that application can
6986 initialize. After initializing, any routine anywhere in the
6987 code (including library) can use RNG without allocating a new
6988 RNG object. This was done to allow this sort of use of the
6989 RNG in code that has no chance to allocate RNG object. All
6990 applications currently allocate this and many routines in the
6991 library use this. Affected file lib/silccrypt/silcrng.[ch].
6993 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6994 it to use the Global RNG API.
6996 * Defined Authentication Payload into protocol specification that
6997 is used during SILC session to authenticate entities. It is
6998 used for example by client to authenticate itself to the server
6999 to obtain server operator privileges.
7001 Implemented this payload into the lib/silccore/silcauth.[ch].
7002 Implemented also routines for public key based authentication
7003 as the new protocol specification dictates.
7005 Moved definitions of different authentication methods from
7006 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
7008 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
7009 silc_pkcs_verify and silc_pkcs_sign_with_hash and
7010 silc_pkcs_verify_with_hash functions into the file
7011 lib/silccrypt/silcpkcs.[ch].
7013 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7015 * The client entry's userinfo pointer must be always valid.
7016 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
7017 will fail since it requires the userinfo. Now, the userinfo
7018 is allocated as "" if actual userinfo does not exist. Actually,
7019 it must exist and it is totally Ok to drop client connections
7020 that does not announce the userinfo. However, we will make
7021 this workaround for now.
7023 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
7024 to return the remote port by socket.
7026 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7028 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
7029 SILC_SERVER_PENDING_EXEC and added an new macro
7030 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
7031 data or when error occurs while processing the pending command.
7033 Added new argument `destructor' into silc_server_command_pending
7034 and to the SilcServerCommandPending object. This destructor is
7035 now called after calling the pending callback or if error occurs
7036 immediately. If error occurs the actual pending callback won't
7037 be called at all - only the destructor. The destructor may be
7038 NULL if destructor is not needed.
7040 All this applies for client library code as well. Similar
7041 changes were made there as well for the pending commands.
7043 In the client, the application must now allocate the
7044 SilcClientCommandContext with the silc_client_command_alloc
7047 * Added reference counter to the SilcServerCommandContext. Added
7048 function silc_server_command_alloc and silc_server_command_dup
7051 Same type of functions added to the client library for the same
7054 * Removed the cmd_ident from IDListData away since it is now
7055 global for all connections. It is the command identifier used
7056 in command sending and with pending commands. The affected file
7059 * Added reference counter to the SilcSocketConnection objecet to
7060 indicate the usage count of the object. The object won't be
7061 freed untill the reference counter hits zero. Currently only
7062 server uses this, and client ignores it. The client must be
7063 set to use this too later. The affected files are
7064 lib/silccore/silcsockconn.[ch]. Added also the function
7065 silc_socket_dup to increase the reference counter.
7067 This was mainly added because it is possible that the socket
7068 is removed underneath of pending command or other async
7069 operation. Now it won't be free'd and proper DISCONNECTING
7070 flags, etc. can be set to avoid sending data to connection that
7071 is not valid anymore.
7073 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
7074 the connection. After that it sets SILC_SET_DISCONNECTED.
7075 It is, however, possible that the socket data is not still freed.
7076 The silc_server_packet_process now checks that data is not
7077 read or written to connection that is DISCONNECTED. The socket
7078 get's freed when the reference counter hits zero.
7080 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7082 * Changed the client operation API: channel_message operation's
7083 `sender' is now the client entry of the sender, not the nickname
7084 and the `channel' is the channel entry, not the channel name.
7086 In the private_message operation the `sender' is now also the
7087 client entry of the sender not the nickname.
7089 Affected file is lib/silcclient/ops.h and all applications
7090 using the client operations.
7092 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7094 * Moved the calling of ops->connect() from connect_to_server_final
7095 into receive_new_id functin since that is the point when the
7096 client is actually allowed to send traffic to network. The
7097 affected file is lib/silcclient/client.c.
7099 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7101 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
7102 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
7103 (if needs broadcasting) instead of broadcasting the packets one
7104 by one which would make a burst in the network traffic.
7106 * Added `broadcast' argument to the functions in silcd/server.[ch]
7107 silc_server_create_new_channel[_with_id] to indicate whether
7108 to send New Channel packet to primary router.
7110 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7112 * Added new function into the silcd/server.[ch] files:
7113 silc_server_create_new_channel_with_id to create new channel with
7114 already existing Channel ID.
7116 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
7117 lib/silccore/silcpacket.h. This packet is used t send list of
7118 Set Mode payloads inside one packet. Server uses this to set
7119 the modes for the channels and clients on those channels, that it
7120 announced to the router when it connected to it. The protocol
7121 specification has been updated accordingly.
7123 * The silc_server_new_channel did not handle the packet coming
7124 from normal server as it normally does not send that. However,
7125 when it announces its channels it does send it. Implemented
7126 the support for that.
7128 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
7129 into the file lib/silccore/id.h.
7131 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7133 * Fixed memory leaks in the functions silc_idlist_del_client,
7134 silc_idlist_del_channel and silc_idlist_del_server in the file
7135 silcd/idlist.c. All of those leaked like a sieve.
7137 * Fixed some small memory leaks in the client's function
7138 silc_client_notify_by_server.
7140 * Added functions into silcd/server.c: silc_server_announce_clients,
7141 silc_server_announce_channels and silc_server_announce_server.
7142 These functions are used by normal and router server to announce
7143 to its primary router about clients, channels and servers (when
7144 router) that we own. This is done after we've connected to the
7147 These functions effectively implements the following packet types:
7148 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
7149 and SILC_PACKET_NEW_ID_LIST.
7151 * Added new functions into the silcd/packet_receive.[ch]:
7152 silc_server_new_id_list, silc_server_new_channel_list and
7153 silc_server_new_channel_user_list to handle the incoming
7154 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
7156 * Added support of changing Channel ID in the function
7157 silc_server_replace_id. If the server that announces a channel
7158 to the router already exists in the router (with same name but
7159 with different Channel ID), router is responsible to send
7160 Replace ID packet to the server and force the server to change
7161 the Channel ID to the one router has.
7163 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
7164 client that the Channel ID has been changed by the router. The
7165 normal server sends this to the client. Client must start using
7166 the new Channel ID as the channel's ID.
7168 Implemented handling of this new type into lib/silcclient/client.c
7169 into the function silc_client_notify_by_server.
7171 * Added new function silc_idlist_replace_channel_id into the files
7172 silcd/idlist.[ch] to replace the Channel ID.
7174 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7176 * Call silc_server_command_identify_check always when processing
7177 the IDENTIFY command in silcd/command.c
7179 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7181 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
7182 send keepalive packets. The packet can be sent by clients,
7183 servers and routers.
7185 Added function silc_socket_set_heartbeat into the file
7186 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
7187 If not set, the heartbeat is not performed. The actual
7188 heartbeat is implemented in the low level socket connection
7189 library. However, application is responsible of actually
7192 Added silc_server_send_heartbeat to send the actual heartbeat
7193 packet into silcd/packet_send.[ch]. Server now performs
7194 keepalive with all connections.
7196 * Added silc_task_get_first function into lib/silcutil/silctask.c
7197 to return the timeout task with shortest timeout. There was a bug
7198 in task unregistration that caused problems. TODO has been
7199 updated to include that task system must be rewritten.
7201 * The client library will now resolve the client information when
7202 receiving JOIN notify from server for client that we know but
7203 have incomplete information.
7205 * Rewrote parts of silc_server_remove_from_channels and
7206 silc_server_remove_from_one_channel as they did not remove the
7207 channel in some circumstances even though they should've.
7209 * Encryption problem encountered in server:
7211 The LEAVE command used to send the Channel Key packet to the
7212 router immediately after generating it. However, the code
7213 had earlier sent Remove Channel user packet but not immediately,
7214 ie. it was put to queue. The order of packets in the router
7215 was that Channel Key packet was first and Remove Channel User
7216 packet was second, even though they were encrypted in the
7217 reverse order. For this reason, MAC check failed. Now, this
7218 is fixed by not sending the Channel Key packet immediately but
7219 putting it to queue. However, this is more fundamental problem:
7220 packets that are in queue should actually not be encrypted
7221 because packets that are sent immediately gets encrypted
7222 actually with wrong IV (and thus MAC check fails). So, packets
7223 that are in queue should be encrypted when they are sent to
7224 the wire and not when they put to the queue.
7226 However, the problem is that the current system has not been
7227 designed to work that way. Instead, the packet is encrypted
7228 as soon as possible and left to the queue. The queue is then
7229 just purged into wire. There won't be any fixes for this
7230 any time soon. So, the current semantic for packet sending
7233 o If you send packet to remote host and do not force the send
7234 (the packet will be in queue) then all subsequent packets to the
7235 same remote host must also be put to the queue. Only after the
7236 queue has been purged is it safe again to force the packet
7239 o If you send all packets immediately then it safe to send
7240 any of subsequent packets through the queue, however, after
7241 the first packet is put to queue then any subsequent packets
7242 must also be put to the queue.
7244 Follow these rules and everything works fine.
7246 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7248 * Added new function silc_server_remove_clients_by_server to
7249 remove all client entries from ID list when the server connection
7250 is lost. In this case it is also important to invalidate all
7251 client entires as they hold the invalid server entry. This
7252 fixes fatal bug when server has lost connection and will reconnect
7255 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7257 * Made some sanity checks to silc_server_daemonise like to check
7258 whether the requested user and group actually exists.
7260 * Added sanity check to SKE's silc_ske_responder_finish to check
7261 that the public and private key actually is valid.
7263 * Invalidate the client's nickname when receiving Replace ID
7264 packet and the Client ID is being replaced. This means that the
7265 server will query the nickname if someone needs it (client)
7268 * Sort the ID Cache in client library when the ID Cache data
7269 has changed (needs sorting).
7271 * Do not allow for SILC client to create several connections to
7272 several servers. The client does not support windows right now
7273 and generating multiple connections causes weird behaviour.
7275 Irssi-silc client does support windows and can handle several
7276 connections without problems, see: www.irssi.org and SILC plugin.
7278 * Fixed some places where client was added to the IDList. The
7279 rule of thumb is following (in order to get everything right):
7280 If the client is directly connected local client then the
7281 `connection' argument must be set and `router' argument must be
7282 NULL to silc_idlist_add_client function. If the client is not
7283 directly connected client then the `router' argument must
7284 bet set and the `connection' argument must be NULL to the
7285 silc_idlist_add_client function.
7287 * The funtion silc_server_packet_send_local_channel actually did
7288 not check whether the client was locally connected or not. It
7289 does that now. Fixed a bug related to LEAVE command.
7291 * Fixed Remove Channel User payload parsing bug in server's
7292 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
7294 * The server's silc_server_save_channel_key now checks also the
7295 global ID list for the channel as it might not be in the local
7296 list. Fixed a bug related to LEAVE command.
7298 * Is this the end of the [<unknown>] buglet that has been lurking
7299 around for a long time? A little for loop fix in server's
7300 silc_server_command_whois_parse that is used by both IDENTIFY
7301 and WHOIS command. At least, this was a clear bug and a cause
7302 of one type of [<unknown>] buglet.
7304 * WHOIS and IDENTIFY commands call the function
7305 silc_server_command_[whois/identify]_check function even if
7306 we are not router server.
7308 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7310 * Added --with-gmp configuration option. If set the GMP
7311 is always compiled in the SILC source tree. If not set then
7312 it is checked whether the system has the GMP3 installed. If
7313 it has then the GMP won't be compiled (the system's headers
7314 and library is used), if it doesn't have it then the GMP is
7315 compiled in the SILC source tree.
7317 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7319 * Changed RSA private exponent generation to what PKCS #1
7320 suggests. We try to find the smallest possible d by doing
7321 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
7322 not security fix but optimization.
7324 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7326 * Added new config entry [Identity] to fork the server and run
7327 it as specific user and group. A patch from Bostik.
7329 * Imported Dotconf configuration library into lib/dotconf.
7330 This will be used to create the SILC configuration files later.
7331 It will appear in the distsribution after this commit.
7333 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7335 * A big code auditing weekend happening. Auditing code for
7336 obvious mistakes, bugs and errors. Also, removing any code
7339 Removed files for being obsolete:
7341 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
7342 inline in the file lib/silcutil/silcbuffer.h)
7344 o lib/silcutil/silcbufutil.c (the header has inline versions)
7346 Changed code to fix possible error conditions:
7348 o The buffer formatting routines now check that the destination
7349 buffer really has enough space to add the data. This applies for
7350 both buffer formatting and unformatting
7351 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
7352 unformatting was changed to accomodate following rules:
7353 XXX_*STRING_ALLOC will allocate space for the data into the pointer
7354 sent to the function while XXX_*STRING will not allocate or copy
7355 the data into the buffer. Instead it sets the pointer from the
7356 buffer into the pointer sent as argument (XXX_*STRING used to
7357 require that the pointer must be allocated already). This change
7358 makes this whole thing a bit more consistent and more optimized
7359 (note that the data returned in the unformatting with XXX_*STRING
7360 must not be freed now). The routines return now -1 on error.
7362 o Tried to find all code that use buffer_format and buffer_unformat
7363 and added return value checking to prevent formatting and
7364 especially unformatting errors and possible subsequent fatal
7367 o Changed ske->x and ske->KEY to mallocated pointers in
7368 lib/silcske/silcske.h. Fixed possible data and memory leak.
7370 o Added return value checking to all *_parse* functions. Fixed
7371 many memory leaks as well.
7373 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
7374 so that buffer overflows would not happen. All code now also
7375 checks the return value as it can fail.
7377 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7379 * Added reconnection support to server if the normal server looses
7380 its connection to the router (for example if router is rebooted).
7381 The server performs normal reconnection strategy implemented
7382 to the server. Affected file silcd/server.c.
7384 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7386 * Added new packet type SILC_PACKET_SET_MODE that is used to
7387 distribute the information about changed modes (for clients,
7388 channels and clients channel modes) to all routers in the
7389 network. Updated the protocol specification accordingly.
7391 Added functions into silcd/packet_send.c and
7392 silcd/packet_receive.c: silc_server_send_set_mode,
7393 silc_server_set_mode.
7395 Added new files silcmode.[ch] into lib/silccore that implements
7396 the encoding and decoding of Set Mode Payload. Added new type
7397 SilcSetModePayload. Moved the definitions of different modes
7398 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
7400 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7402 * Oops, a little mistake in server's connection authentication
7403 protocol. The protocol is not ended with FAILURE but with
7404 SUCCESS if the authentication is Ok. :) Affected file is
7407 * Implemented NICK_CHANGE notify handling in server in the file
7408 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
7409 the local clients on the channel. After the changing nickname
7410 in router environment snhould work and the [<unknown>] nickname
7411 should appear no more.
7413 The silc_server_replace_id function that receives the Replace ID
7414 payload now sends the NICK_CHANGE notify type also in the file
7415 silcd/packet_receive.c
7417 * Changed WHOIS and IDENTIFY command to support the maximum amount
7418 of arguments defined in protocol specs (3328 arguments). This
7419 fixed a bug that caused problems when there were more than three
7422 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7424 * Added extra parameter, command identifier, to the
7425 silc_client_send_command so that explicit command identifier
7428 Changed that ID list routines uses specific command identifier
7429 when sending WHOIS/IDENTIFY requests to the server so that they
7430 can be identified when the reply comes back.
7432 Affected files lib/silcclient/command.[ch],
7433 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
7435 * Added `sender' argument to silc_server_packet_send_to_channel
7436 to indicaet the sender who originally sent the packet to us
7437 that we are now re-sending. Ignored if NULL. Affected file
7438 silcd/packet_send.[ch].
7440 * Added some server statistics support in silcd/server_internal.h
7441 SilcServerStatistics structure and around the server code. Also
7442 send some nice statistics information when client is connecting
7445 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7447 * Fixed channel ID decoding in server's JOIN command reply in
7448 silcd/command_reply.c
7450 * Fixed braodcasting of replace ID payload to not to send it if
7451 we are standalone server in silcd/packet_receive.c.
7453 * Fixed all channel message sending routines to not to send
7454 packets to clients that has router set, since they are routed
7455 separately in the same function earlier. Affects file
7456 silcd/packet_send.c and all channel packet sending functions.
7458 * In USERS reply, res_argv[i] are not allocated, the table
7459 is allocated. Thus changed that free the table, not its
7462 * In server's whois_check and identify_check if the client is
7463 locally connected do not send any WHOIS commands - they are not
7466 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7468 * Fixed some minor bugs in client when sending WHOIS command. The
7469 arguments was in wrong order.
7471 * Removed statis function add_to_channel from server in
7472 silcd/command.c that was previously used with the joining but
7475 * Tested USERS command in router environment successfully with two
7476 routers, two servers and two clients.
7478 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7480 * Reorganized the USERS command and command reply in client library
7481 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
7482 When the command is given by user we register a pending command
7483 callback that will reprocess the command after the reply has been
7484 received from the server. When reprocessing the packet we then
7485 display the information. Thus, the USERS information is displayed
7486 now in the command callback instead of in the command reply
7487 callback. The processing of the command is same as previously
7488 when server has sent the command reply in the JOINing process.
7490 * Added to USERS command in silcd/command_reply.c to join the client,
7491 we didn't use to know about, to the channel after we've created
7492 a client entry for it. Also, for clienet we did know already still
7493 check whether it is on the channel or not and add it if not.
7495 * Removed silc_server_command_join_notify as the function and its
7498 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7500 * Changed the client's pending command handling to the same as the
7501 server's pending command handling. It is also now possible to
7502 execute command reply functions from other command reply
7503 function as the function callbacks for commands and command
7504 replies are one and same. The pending commands are not static
7505 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
7506 in client connection context. Thus, pending commands are server
7507 connection specific as it is convenient.
7509 Changed the function silc_client_command_pending and
7510 silc_client_command_pending_del and added new function
7511 silc_client_command_pending_check. Removed the
7512 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
7515 * Added cmd_ident, current command identifier, to the client
7516 connection context in lib/silcclient/client.h to keep track on
7517 command identifiers used in command sending. Client's command reply
7518 function handling now supports the mandatory command identifiers.
7520 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
7521 funtions in client to fully support pending command callbacks.
7523 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
7524 as one of the arguments to the application in the command reply
7527 * NOTE: The FORWARDED flag is depracated. It used to be depracated
7528 before first releasing SILC but came back. Now it is removed again
7529 and should come back nomore. The FORWARDED flag was used only
7530 by the JOINing procedure by forwarding the command packet to router.
7531 Now, the JOINing procedure has been changed to more generic (due
7532 to various router environment issues) and FORWARDED is not needed
7533 anymore for anything. The protocol specification is yet to be
7536 Now, removed silc_server_packet_forward from server and the flag
7537 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
7539 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7541 * Renamed NAMES command to USERS command. The NAMES was named that
7542 due to historical reasons. Now it is renamed. Also, rewrote
7543 parts of the USERS command. The nickname list is not sent anymore
7544 by the server. Only Client ID and mode lists are sent in the USERS
7545 command. Changed this also to the protocol specification.
7547 The client now resolves the names and stuff after it receives
7548 the USERS list from the server when joining to the channel.
7550 * WHOIS and IDENTIFY commands has been changed to support multiple
7551 Client ID's per command. One can now search for multiple users
7552 in the network by sending only one WHOIS or IDENTIFY command.
7553 Changed the code and the protocol specifications.
7555 * Removed silc_server_command_identify_parse and changed that IDENTIFY
7556 uses silc_server_command_whois_parse to parse the request. */
7558 * If normal server, do not parse the WHOIS and IDENTIFY requests
7559 before sending it to the router. Saves some time.
7561 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7563 * Fixed JOIN command on client library. Wrong number of arguments
7564 used to crash the client.
7566 * Added silc_server_channel_has_global function to check whether
7567 channel has global users or not.
7569 * Added silc_server_channel_has_local function to check whether channel
7570 has locally connected clients on the channel.
7572 * The silc_server_remove_from_one_channel now checks whether the
7573 channel has global users or not after given client was removed from
7574 the channel. It also checks whether the channel has local clients
7575 on the channel anymore. If it does not have then the channel entry
7576 is removed as it is not needed anymore.
7578 * The silc_server_notify now checks on JOIN notify whether the joining
7579 client is one of locally connected or global. If it is global then
7580 the channel has now global users on the channel and that is marked
7581 to the channel entry. Also, it now saves the global client to
7582 global list who is joining and JOINs it to the channel. This is
7583 for normal server, that is.
7585 Changed silc_server_send_notify_on_channel,
7586 silc_server_packet_relay_to_channel and
7587 silc_server_packet_send_to_channel check if we are normal server
7588 and client has router set (ie. global client) do not send the
7589 message to that client, as it is already routed to our router.
7591 * Implemented LEAVE notify type handling in silc_server_notify
7594 * Tested LEAVE command in router environment successfully. Tested
7595 with two routers, two servers and two clients.
7599 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
7601 * Implemented SIGNOFF notify type handling in silc_server_notify
7604 * silc_server_remove_id now removes the client entry from all channels
7605 it has joined and thusly sends SIGNOFF notify type.
7607 * Rewrote the NAMES list generation in server by removing two excess
7608 loops. The lists are created now inside one loop.
7610 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7612 * silc_server_remove_channel_user checks now also global list
7613 for channel and client.
7615 * silc_server_new_channel_user checks now both local and global
7616 list for channel and client. Fixed a bug in client id decoding.
7617 Used to decode wrong buffer.
7619 * silc_server_channel_message checks now both local and global
7620 list for channel entry.
7622 * Tested channel joining (hence JOIN) in router environment
7623 successfully. Tested with two routers, two servers and two
7626 * Tested channel message sending in router environment successfully.
7628 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7630 * Added silc_server_save_channel_key into server.[ch] to save the
7631 received channel key in Channel Key payload processing. It is
7632 also used in JOIN command reply handling.
7634 Equivalent function silc_client_save_channel_key added into
7635 client.[ch] into client library.
7637 * Changed JOIN command reply to send information whether the channel
7638 was created or not (is existing already) and the channel key
7639 payload. Changed protocol specs accordingly.
7641 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
7642 the request was sent by ID and not by nickname. Crashed on
7645 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7647 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
7648 now correctly save the received data.
7650 * silc_server_free_sock_user_data now notifies routers in the
7651 network about entities leaving the network.
7653 At the same time implemented functions silc_server_remove_id
7654 and silc_server_send_remove_id to receive and send REMOVE_ID
7655 packets. The packet is used to notify routers in the network
7656 about leaving entities. The ID removed will become invalid in
7659 * Added function silc_idlist_del_server into server. Removes and
7660 free's server entry from ID list.
7662 * silc_server_private_message function now checks, if we are router,
7663 that the destination ID really is valid ID, naturally.
7665 * In router when NEW_ID packet is received (for new client) the
7666 hash of the Client ID is saved in the ID Cache but the
7667 client->nickname is set to NULL, instead of putting the hash
7670 IDENTIFY command now also checks that client->nickname must be
7671 valid. If it is not if will request the data from the server who
7672 owns the client. Added new function
7673 silc_server_command_identify_check.
7675 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
7676 to set the command to already allocated Command Payload.
7678 * Tested private message sending in router environment with two
7679 routers, two servers and two clients. Fixed minor bugs and now
7682 * Fixed segfault from client's NAMES command. Used to crash if
7685 * Forwarded packets must not be routed even if it is not destined
7686 to the receiver. Changed server code comply with this.
7688 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7690 * Added `require_reverse_mapping' boolean value to ServerParams
7691 structure. If TRUE (not default) the server will require that
7692 the connecting host has fully qualified domain name.
7694 If the reverse mapping is not required and hostname could not be
7695 found the IP address is used as hostname.
7697 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7699 * Implemented version string checking to both client and server.
7700 The check is incomplete currently due to the abnormal version
7701 strings used in development version of SILC.
7703 * Changed all command functions in server to use the new
7706 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7708 * Changed char *data to unsigned char *data in ID Cache system to
7709 support binary data as ID Cache data. Changed code to support
7710 binary data in lib/silccore/idcache.c.
7712 * Renamed silc_server_packet_relay_command_reply to
7713 silc_server_command_reply as it is normal packet receiving
7714 function. Rewrote the function to accept command replys for
7715 servers and not only for clients.
7717 * Mark remote router always as registered server if we are connecting
7718 to it. Otherwise, commands sent by the router to us are ignored.
7720 * All ID List find routines now returns the ID Cache Entry pointer
7721 as well if requested.
7723 * WHOIS command works now in router environment, tested with two
7724 routers, two servers and two clients.
7726 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
7727 in router environment (as it is almost equivalent to WHOIS) but
7728 hasn't been tested thoroughly. Added new functions:
7730 silc_server_command_identify_parse
7731 silc_server_command_identify_send_reply
7732 silc_server_command_identify_from_client
7733 silc_server_command_identify_from_server
7735 * Disabled route cache adding because adding two different ID's with
7736 same IP replaces the old cache entry thus giving wrong route.
7737 The entry->router->connection is always the fastest route anyway
7738 so route cache may not be needed. Of course, new routes maybe
7739 established after receiving the ID when the entry->router->connection
7740 might not be anymore the most optimal.
7742 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7744 * Add route cache for received ID for fast routing.
7746 * Added silc_server_packet_route to route received packet on router
7747 that is not destined to us.
7749 * Renamed silc_server_get_route to silc_server_route_get.
7751 * Added id_string and id_string_len fields into SilcServer to
7752 include encoded ServerID for fast comparing without excess
7753 encoding of the ID's.
7755 * Cleaned up WHOIS command on server side. Added following static
7758 silc_server_command_whois_parse
7759 silc_server_command_whois_check
7760 silc_server_command_whois_send_reply
7761 silc_server_command_whois_from_client
7762 silc_server_command_whois_from_server
7764 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
7765 arguments in command replies. All command functions should be
7766 updated to use this macro.
7768 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7770 * Minor typo fixes on command reply handling on server.
7772 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7774 * Added silc_server_command_add_to_channel internal routine to add
7775 the client to the channel after router has created the channel and
7776 sent command reply to the server.
7778 * Added generic silc_server_send_command to send any command from
7781 * Use static buffer with ID rendering instead of duplicating data.
7783 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7785 * Fixed a channel user mode bug when joining to a channel server gave
7786 everybody channel founder rights, oops.
7788 * We mark ourselves as the router of the incoming server connection
7789 if we are router ourselves. This way we can check in some packet
7790 sending functions whether it is locally connected server. For
7791 incoming router connections we put NULL.
7793 * For router sending packets locally means now always sending the
7794 packet cell wide; to local clients and local servers. For normal
7795 server sending packet locally means sending it to only local
7798 * Fixed the JOIN command to really work in router environment. If the
7799 channel is created it is always created by the router. Router is
7800 also responsible of making the initial joining to the channel,
7801 sending JOIN notify to the sending server and distributing
7802 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
7803 does not exist server doesn't do anything else but forward the
7804 command to the router which performs everything.
7806 * Added silc_server_send_channel_key function to send the Channel Key
7809 * Added silc_server_create_channel_key to create new channel key. The
7810 channel key is now re-generated everytime someone joins or leaves
7811 a channel, as protocol dictates. Note: channel->key_len is the
7814 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7816 * Splitted server.[ch] finally. Created now packet_send.[ch] and
7817 packet_receive.[ch] to separate packet sending and receiving
7818 routines. The server.[ch] now includes everything else including
7819 actual packet processing (writing and reading data) and other
7822 Renamed silc_server_private_message_send_internal to
7823 silc_server_send_private_message. The routine is still though
7824 used only to relay private messages as server does not send
7825 private messages itself.
7827 Renamed silc_server_new_channel to silc_server_create_new_channel
7828 and added new function sicl_server_new_channel that handles the
7829 incoming New Channel packet. Added also new sending function
7830 silc_server_send_new_channel to send New Channel Payload.
7832 * Added new function silc_server_notify to process incoming notify
7833 packet to the server/router. Server may then relay the notify
7834 to clients if needed.
7836 * Added new function silc_server_new_channel_user to process incoming
7837 New Channel User packet. Router will redistribute the packet and
7838 send JOIN notify to its local clients and locally connected servers
7839 if needed. Normal server will send JOIN notify to its local client
7840 on same channel when received this packet. Added also corresponding
7841 sending function silc_server_send_new_channel_user to sent the
7844 * Added boolean route argument to send_notif_to_channel and
7845 packet_send_to_channel functions to attempt to route the packet
7846 if it is TRUE and send only locally if it is FALSE.
7848 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7850 * silc_server_replace_id now broadcasts the received replace ID
7851 packet if it is not broadcast packet already. The router must
7852 broadcast to inform other routers about changed ID.
7854 * Added backpointer to server's router into SilcServer context in
7855 silcd/server_internal.h.
7857 * Fixed silc_server_packet_broadcast to send correct broadcast
7860 * The channel key is now distributed to the local client as soon
7861 as it is received from the router (in router environment) so that
7862 no other packet may be sent for the channel until client has
7865 * silc_server_remove_channel_user now broadcasts the received
7866 Remove Channel User packet if it is not broadcast packet already.
7867 The router must broadcast to inform other routers about removed
7870 * Added users field into SilcPacketContext that is a reference count
7871 of the context. One can increase the reference count by calling
7872 silc_packet_context_dup which is now changed to just increase the
7873 reference count instead of duplicating the data. The reference
7874 count is decresed by calling silc_packet_context_free that will
7875 free the data after the reference count hits zero.
7877 For now on the packet context and everything allocated into it
7878 (including the raw packet from network) must be freed by calling
7879 the new silc_packet_context_free function. Added also new function
7880 silc_packet_context_alloc that must be used now to allocate the
7881 context. This also means that if a routine is asynchronous from
7882 silc_[client/server]_packet_parse_type the packet context must
7883 be duplicated by calling silc_packet_context_dup. Otherwise it
7884 gets free'd after silc_[client/server]_packet_parse_type returns.
7885 Also, one must remember that if packet is duplicated then its
7886 reference count must be decresed by calling the free function as
7887 many times as it was duplicated.
7889 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7890 from both client and server.
7892 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7894 * Made joining to a channel working in router environment.
7896 * Cleaned up JOIN command on server side and create function
7897 silc_server_command_join_channel internal routine to make the
7900 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7902 * Changed silc_command_pending list to SilcDList. Also, added
7903 `ident' field to SilcServerCommandPending structure to identify
7904 the reply and to call correct callback.
7906 Added silc_server_command_pending_check function to replace the
7907 corresnponding macro. The silc_command_pending list is not
7910 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7911 to set identifier to previously allocated Command Payload. It
7912 is used to set identifier for command when resending Command
7915 * Added silc_command_payload_encode_payload to encode Command
7916 Payload buffer from SilcCommandPayload structure.
7918 * Added silc_argument_payload_encode_payload to encode Argument
7919 payload buffer from SilcArgumentPayload structure.
7921 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7923 * Changed WHOIS command to support router connection on server side.
7924 The whois request is always sent to router unless the server is
7925 standalone server. After server has received the reply from the
7926 router will it send the reply to the client.
7928 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7929 broadcast received broadcast packet. The function is used only
7930 by router. The broadcast packet is always sent to the router's
7933 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7934 render given ID to printable string, for log files for example.
7936 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7938 * Made basic router to router connections working. At least they
7939 can now connect to each other but nothing really works the way
7940 they are supposed - yet.
7942 * Added new initiator token to RouterConnection configuration
7943 file in silcd/serverconfig.[ch]. It is used to tell whether we
7944 are the initiator to the remote router or whether we'll expect
7945 the other end to connect.
7947 * Moved registering of listener task to silc_server_init, hence
7948 the server starts listenning as soon as it is run, even if it
7949 does not have connections to other routers. Let's see how well
7952 * Changed default connection retry timeouts for more suitable in
7955 * Removed cipher and such arguments from silc_idlist_add_client
7956 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7957 Added new function silc_idlist_add_data to add the keys and stuff
7960 * Added SilcIDListData structure and added it to SilcClientEntry
7961 and SilcServerEntry as their first field in the structure. This
7962 way we can explicitly cast the ID entries to the SilcIDListData
7963 structure and get common data for the entries. In past, we had
7964 to first check what type of connection it is and then cast it to
7965 correct ID entry type. Now, we can directly cast the opaque
7966 pointer to the SilcIDListData (no matter what ID entry it actually
7967 is) and get the data needed.
7969 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7971 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7972 in some circumstances even if threre were timeout tasks, though not
7973 IO tasks, but tasks anyway. Now fixed.
7975 * Defined SilcServerConnection structure to hold connection specific
7976 stuff about directly connected servers and routers. The definition
7977 is currently in silcd/server_internal.h. I thought about having
7978 a bit more important role fro this struct but for now it is used
7979 only when connecting to other server (or router actually).
7981 * Added connecting retry support in server when connecting to
7982 router(s). The retry feature implement exponential backoff
7983 algorithm. Also, added SilcServerParams structure to hold default
7984 parameters for server. For now, it include these retry settings
7985 and are hard coded. After server is moded to be as Silc Server
7986 Library this structure will be more important.
7988 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7990 * Changed client librarys channel->clients table to SilcList and
7991 changed code accordingly.
7993 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7995 * Changed client's channel table to SilcList and changed code
7996 accordingly. Also changed SilcChannelClientEntry to include back-
7997 pointer to the channel so that client entry can use that structure
7998 as list as well and we have fast cross-reference to the channel.
7999 This change dramatically decreased the complexity of channel
8000 handling with client entry and vice versa (removed one extra
8001 loop when searching for channel entry from many functions).
8003 * Changed server->sim from table to SilcDList and changed code
8006 * NAMES command can now be used from user interface. It will show
8007 the user list on the channel, neatly.
8009 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
8010 Code now saves realname of the user if it becomes available.
8012 * Renamed configure.in to configure.in.pre and made ./prepare
8013 script to automatically add correct version string to
8014 configure.in which it creates from configure.in.pre.
8016 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8018 * NAMES command reply now shows users mode with the nickname when
8021 * Moved silc_client_ch[u]mode[_char] functions from
8022 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
8023 place sucks, they are utility functions and should be in some
8026 * Fixed some unsigned int's to unsigned short's. Patch by cras.
8028 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
8031 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8035 * Added TRQ (efficient deque and list library) into lib/trq. This is
8036 a very good list library that is currently used in the SILC. Defined
8037 SilcList API over the library because I didn't like the API very
8038 much. See lib/trq/silclist.h for the API and examples of how to
8039 use the API. Fixed various places in the code to use the new
8040 SilcList API. The SilcList is meant for lists that has a structure
8041 already defined as a list. It is not suitable to add just some
8042 context to the list (in TRQ, the context is the list actually).
8044 So, I defined SilcDList that can be used for the purpose where
8045 predefined list structure does not exit. This can be used as
8046 such list. Now some context just can be added to the SilcDList.
8047 Currently this list is not used in the SILC just yet, though there
8048 are a lot places where this can replace dynamically allocated
8049 tables and I will fix these places, later, to use SilcDList.
8050 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
8051 and use TRQ internally).
8053 Also fixed some annoying warning messages that the original TRQ
8054 code generated. Also minor changes to TRQ's Makefile.in.
8056 * Added support for querying by Client ID to both WHOIS and
8057 IDENTIFY commands into server, as required by the protocol.
8059 * Removed method function pointers from SilcBuffer structure. They
8060 weren't used to anything and just increased the context size for
8061 no good reason. This change also made silc_buffer_alloc and
8062 silc_buffer_free functions inline functions.
8064 * Disabled command flooding detection support until it's fixed so
8065 that it accepts commands in but does not execute them more than once
8068 * Added silc_net_localhost(), to return local hostname, into
8069 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
8070 that must be initialized before calling silc_client_init.
8072 * Added new function: silc_server_send_notify_on_channels to send
8073 notify messages to all channels client has joined. It is assured
8074 that the message is sent only once per client.
8076 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
8077 lib/silcutil/silcutil.[ch] as silc_format function. The new
8078 function is generic and is used by server as well, not only by
8079 the logging routines.
8081 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
8082 the provided version string was not acceptable. Added new function:
8083 silc_ske_check_version into lib/silcske/silcske.h. The function
8084 must be implemented by the application (client or server) and it
8085 does not reside in the SKE library. The function checks the version
8086 string remote end sent.
8088 * Added back pointers (to opaque context and to SilcSocketConnection)
8089 into SilcPacketContext structure into lib/silccore/silcpacket.h.
8091 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
8092 duplicate packet context structure.
8094 * Changed `notify' client operation to send same arguments as client
8095 receives from server except for ID's. ID's are mapped to correct
8096 ID entry and that is returned. Also, if channel entry is not sent
8097 by server but the notify is for channel the channel entry is sent
8098 to application (otherwise application doesn't know that it is for
8099 channel (library gets it from packet's Destination ID)).
8101 * Added silc_client_remove_from_channels into client library to
8102 remove a client from all channels it has joined to. Used when
8103 received SIGNOFF notify from server. Added also new function
8104 silc_client_replace_from_channels to replace old ID entry with
8105 new ID entry on all channels. Used when received NICK_CHANGE
8108 * Fixed ID Cache list handling in silc_idlist_get_client in
8109 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
8110 to get (or query) client by ID.
8112 * Updated TODO list.
8114 * Added connection authentication status message defined by the
8115 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
8116 support for these into the code in client and server side.
8118 * Added generic function silc_client_send_command to send any command
8119 with variable argument list. Application should use this function
8120 to send commands if the command functions provided by the library
8121 does not suite for the application's user interface needs.
8123 * Added new `failure' client operation. Application is notified about
8124 received failure packet if client is executing a protocol. In this
8125 case the protocol's execution has failed.
8127 * Added SKE's end notify to send the SKE_SUCCESS notify message that
8128 is required by the protocol.
8130 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
8131 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
8134 * Added status flag to SilcSKE object to indicate realtime status
8135 of the SKE protocol.
8137 * Application receives now exactly same command reply arguments as
8138 the library receives from server. However, if ID is received the
8139 corresponding ID entry is returned to the application (eg. Client
8140 ID is mapped to correct SilcClientEntry entry and that is returned).
8141 Changed command_reply client operation due to this change.
8143 * Changed all ID's in commands and in command replys as ID Payloads.
8144 Change affected both client and server side codes.
8146 All ID's sent in SILC network (with execption of ID's in SILC
8147 Packet header) are sent in ID Payload to support variable length
8150 * Server now notifies nick changes and notifies all clients on
8151 the channels about the new nickname (about the new Client ID,
8154 * Implemented CMODE command to change channel modes. Supports all
8155 channel modes defined by the protocol specs except ban and invite
8156 lists. (Also, private channel key mode is supported but support for
8157 setting private channel key in client is missing, thus, this mode
8158 has no effect on client side (except that server requires that the
8159 client uses private channel key and normal channel traffic does not
8162 Also, invite mode works per se, but INVITE command does not work
8163 yet correctly, so you can set channel as invite only channel but
8164 inviting clients to the channel does not work (it is yet to be
8165 thought what's the best way to do it).
8167 * Added new command SILC_COMMAND_CUMODE to change user mode on the
8168 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
8169 Implemented CUMODE command to change user's mode on the channel.
8170 Supports all modes defined by the protocol specs.
8172 * Added NAMES command reply to return users modes on the channel.
8174 * Removed unnecessary and slow ciphers from lib/silccrypt.
8176 * Set SO_KEEPALIVE option to connection sockets by default.
8178 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
8180 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
8181 redefined the Notify Payload into protocol specs.
8183 * Added silc_id_payload_parse_id to get ID directly from raw
8186 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8188 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
8189 accept searching by Client ID as well.
8191 * Added support for LEAVE and SIGNOFF notify types in client library.
8193 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
8194 to parse ID Payload from raw data.
8196 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8198 * Added flags parameter into silc_ske_assemble_security_properties
8199 function in lib/silcske/silcske.[ch].
8201 * Changed notify client operation to fit better for notify messages
8202 sent by server. The notify payload received from server is now
8203 passed to the application (after parsing it to SilcNotifyPayload).
8204 It is application's responsibility to retrieve the arguments
8205 from the payload and show the message the way it wants. The message
8206 sent by server is implementation specific.
8208 * Changed public keys to comply with the protocol specification.
8209 Old public keys are not supported anymore and are not compatible.
8211 * Removed nickname from Channel Payload as the latest draft removed
8212 it. The client must resolve the nickname from the NAMES command
8213 reply received when it joined the channel.
8215 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
8217 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8219 * Fixed some errors in protocol specification drafts.
8221 * Created lib/silccore/silcnotify.c to implement Notify Payload
8222 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
8223 generic payloads described by protocol specifications. The file
8224 includes implementations for ID Payload and Argument Payload.
8226 * Changed Command Payload implementation to use the new Argument
8227 Payload. Changed command_xxxx_payload to command_payload_xxxx
8228 to comply with SILC coding conventions.
8230 * Added suppport for Argument Payload handling in Notify Payload
8231 implementation as protocol requires it. Added the new support
8232 into server and client lib as well.
8234 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8236 * Added support for multiple nicknames on same channel. [n] is
8237 added locally to the nickname if there are more than one same
8238 nicknames on the channel.
8240 * Server now sends all nicknames that matched WHOIS request.
8241 Client also shows the list received from server.
8243 * Added TOPIC command to client side. User can now set and show
8244 current topic on channel.
8246 * Added MOTD command to client and server. Also, server sends the
8247 motd when client connects to the server.
8249 * Changed version strings to comply ISO 8601.
8251 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8253 * Fixed protocol error handling in client library. It should now
8254 cope even if the SKE fails for some reason.
8256 * Made new protocol specification drafts for submitting to IETF.
8258 * Implemented TOPIC command to server in silcd/command.c.
8260 * Added two new notify types into lib/silccore/silcnotify.h:
8261 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
8262 notify nickname change and topic setting/change on a channel.
8264 * API change of command_reply operation in client library. The
8265 application gets now the status type received from server as well.
8267 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8269 * Removed the function just added to lib/silcutil/silcschedule.[ch].
8271 * Cras fixed and optimized the packet handling even further and
8272 it should work now. Minor change to the prototype of function
8273 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
8275 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8277 * Added new function into lib/silcutil/silcschedule.[ch]:
8278 silc_schedule_with_fd to select() a specified fd. The function
8279 returns after timeout expires or data arrives or goes. The
8280 function is used by packet routines to wait that all data is
8281 received from network.
8283 * Fixed data reading from network in lib/silccore/silcpacket.c.
8284 The code now assures that all data is read from the fd and then
8285 continues packet processing. This was a bug fix since the code
8286 used to drop some data in some circumstances.
8288 * Added new function into lib/silcclient/client.[ch]:
8289 silc_client_start_key_exchange to start key exchange after
8290 connection has been established to server. The code internally
8291 now uses this funtion but its main purpose was to provide it
8292 for applications that perform their own connecting. After
8293 application has created a connection it merely calls this
8294 function to start the key exchange between client and server.
8295 The library takes care of everything else after that.
8297 Updated also lib/silcclient/README to explain the usage of
8300 * Do not send to application information that connection has
8301 been established. Application gets notified it by connect
8304 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8306 * Applied cras's patch to add silc_schedule_one function. The
8307 function runs scheduler once and returns.
8309 * Fixed the scheduler after cras messed it up. The timeout
8310 handling works now as it's supposed to work.
8312 * Added into lib/silccore/ silcnotify.h to include notify
8313 message types support. Changed silc_server_send_notify*
8314 functions, in server.[ch], to support those new notify types.
8315 Added the support for the notify types into client library,
8316 as well. Added new notify client operation into ops.h in
8319 * Changed silc_server_packet_send_to_channel to send normal
8320 packets instead of just channel message packets. The function
8321 is now used to send the notify packets to channels. It is not
8322 used to send channel message packets anymore, as server never
8325 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
8326 va_arg()s as it seems to require it nowadays. I guess, if SILC
8327 is compiled with older va_arg() the new code should work anyway.
8329 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8331 * Splitted core library. Core library (lib/silccore) includes
8332 now only SILC protocol specific core (and common) components.
8333 Created new utility library (lib/silcutil) that includes more
8334 generic purpose stuff. The stuff for util library was taken
8335 from the old core library. This was minor and easy split.
8337 * Created SILC Client Library (lib/silcclient) that includes
8338 implementation of the SILC client without user interface. This
8339 was major move from silc/ directory. The code has been changed
8340 so that it is transparent towards the user interface. The
8341 silc/ directory includes now the same user interface as before
8342 and it uses the new client library. Read lib/silcclient/README.
8343 Basicly, the client library performs everything else related
8344 to SILC except user interface handling. Also, configuration
8345 files are considered to be part of user interface and library
8346 does not handle them.
8348 This change also changed a lot of structures, function naming etc.
8349 Most important change was that SilcClientWindow object was
8350 renamed to SilcClientConnection in the client library. Created
8351 also new file lib/silcclient/ops.h. Also added new files
8352 silc/local_command.[ch] and silc/client_ops.[ch].
8354 All these changes were made to make it easier for user interface
8355 designers to create what ever user interface for the SILC client
8358 It is also expected that the server will be moved to lib
8359 directory as well and SILC Server Library will be created;
8360 sometimes in the future.
8362 * Removed Local commands from lib/silccore/silccommand.h as
8363 they are application specific and new client library does not
8364 handle any of those anymore.
8366 * Several functions moved to lib/silcutil/silcutilc.[ch] from
8367 old client implementation in silc/.
8369 * Added support for callback functions in SILC_LOG_* macros.
8370 Application can now set its own callbacks that will be called
8371 instead of using the default functions that will always print
8372 the debug messages to stderr (or stdout). Also, debugging can
8373 now be disabled by setting silc_debug to FALSE and re-enabled by
8374 setting it to TRUE. Note, that logging will still work even
8375 if debugging is disabled.
8377 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
8378 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
8379 silc_log_reset_debug_callbacks.
8381 * To enable debugging in silc client one must give now -d
8382 option on command line.
8384 * Changed silc_schedule_init to automatically allocate task queues
8385 if they are not allocated before calling it.
8387 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8389 * Added GMP 3.1 into math library.
8391 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8393 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
8394 a channel in SILC network. The packet is used by servers and
8395 routers to notify other routers that user has left a channel.
8396 This little feature was missing until now. Added the feature
8397 to protocol specification as well.
8399 Added functions: silc_server_send_remove_channel_user and
8400 silc_server_remove_channel_user into server.[ch].
8402 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
8403 lib/silccore/silcpacket.h. However, they are not implemented
8406 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8408 * Fixed joining to a channel and sending channel messages
8409 between server and router. The channel message sending should
8410 now work inside a cell.
8412 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8414 * Fixed the private message sending between server and router.
8415 The private message sending should now work inside a cell.
8417 * Added silc_server_replace_id into server.[ch] to replace
8418 existing ID in the SILC network.
8420 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
8421 and silc_idlist_replace_server_id into idlist.[ch] in server.
8423 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8425 * Fixed the server to server connections. Server can again now
8426 connect to router. Router to router connections probably does
8429 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8431 * Added dynamic protocol registering support. Now protocols can
8432 registered and unregistered on the fly. Patch by cras.
8434 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8436 * Added lib/contrib directory to hold routines that some platforms
8437 don't have but are needed by SILC.
8439 * Added getopt.c, getopt1.c and getopt.h from GNU C library
8440 into lin/contrib to provide getopt() and getopt_long() for
8441 those who don't have it.
8443 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8445 * Added AWAY command to client. When away message is set and
8446 client receives a private message packet the client automatically
8447 replies to the sender with the away message.
8449 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
8450 bug seemed to be the cause of recent problems when compiling
8453 * Added version detection support to SKE protocol specification
8454 and added the new changes to the SKE implementation as well.
8455 There were other minor changes in the SKE protocol as well.
8457 Many changes in lib/silcske/silcske.[ch] and in
8458 lib/silcske/payload.[ch].
8460 * Added ^U functionality, clear input line. Patch from cras.
8462 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8464 * Mainly small bugfixes on core library. Fixed some debugging
8465 logging and buffer overflow in silclog.c.
8467 * Updated config.sub and config.guess on the distribution tree.
8469 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8471 * Added command lagging support in server. Client may execute
8472 commands now only once in two seconds.
8474 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8476 * Optimized packet reception. MAC computation and checking is now
8477 also more optimized. A lot previously duplicated code is now
8478 used as generic by both client and server.
8480 * Fixed key pair generation in clientutil.c
8482 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8484 * Added into lib/silccore/silcbufutil.[ch] new function;
8485 silc_buffer_realloc.
8487 * Moved generic packet sending/encryption functions to
8488 lib/silccore/silcpacket.[ch] from client and server. Some
8489 rewriting of the functions.
8491 * Moved all generic packet reception/decryption functions to
8492 lib/silccore/silcpacket.[ch] from client and server. The
8493 packet processing is now much cleaner in both client and server.
8494 These were major changes in both client and server.
8496 * Created many common functions in server to do packet sending.
8497 Previously code were duplicated a lot, this has been removed
8500 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8502 * Rewrote major parts of the ID cache system. Don't know
8503 whether it is better now or not but at least the API is more
8506 * Major rewrite on ID cache stuff on client because of the ID
8507 cache API changes. Added idlist.c to client.
8509 * Also major rewrite on ID cache stuff on server as well.
8510 Major rewrite of idlist.[ch]. SilcXXXList's are now named
8511 SilcXXXEntry's. We won't keep anymore idlist specific pointers
8512 in hand, instead they are all put into the ID cache system now.
8513 All server_idlist_* routines uses ID cache now instead of
8514 traversing its own lists (those lists does not exist anymore).
8515 SilcIDList though still exists. Also, SilcXXXEntry's are
8518 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8520 * Finally made the SKE implementation compliant to the protocol
8521 specification. All mp integers are now binary encoded as
8522 opposed being HEX encoded.
8524 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
8527 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
8528 functions: silc_[encode/decode]_pem. Also added function
8529 silc_encode_pem_file to PEM encode with newlines ('\n') for
8532 * SILC public keys are now encoded either PEM or binary. Same
8533 option is for private keys as well. By default private keys
8534 are binary encoded and public keys PEM encoded. Silly HEX
8535 encoding were removed.
8537 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
8538 function to create fingerprints.
8540 * Fixed a bug in SHA1; does not change the original data anymore.
8542 * Partly implemented INFO command on client and server side.
8543 Fixed CLEAR command. Changes to SERVER command; show current
8544 server(s) when giving command without arguments. Added
8545 VERSION command to client.
8547 * Added check to server that unregistered connections cannot
8548 execute commands (unless it is specificly allowed).
8550 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8552 * Fixed screen refresh.
8554 * Fixed channel joining bug from client. On some circumstances
8555 client tried to join to a channel it had already joined.
8557 * Added public key verification process into client's protocol.c.
8558 The client now verifies the public key from user and saves
8559 it into ~./silc/serverkeys/ directory.
8561 Added into: clientutil.[ch]: silc_client_verify_server_key.
8563 * Changed SKE protocol's silc_ske_initiator_finish function
8564 to accept callback function that verifies the received public
8565 key. Removed old silc_ske_verify_public_key function.
8567 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8569 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
8570 silc_pkcs_private_key[_data]_set.
8572 * Made the password and public authentication more cleaner in
8573 server's protocol.c.
8575 * Removed historic and obsolete protocol `channel_auth' from
8576 both client and server.
8578 * Removed wrong way of sending command status messages from
8579 server to client in server's command.c. The old way violated
8580 protocol specification.
8582 Changes to silccore/silccommand.[ch]: removed
8583 silc_command_encode_status_payload -> not needed anymore,
8584 changed silc_command_encode_payload_va to accept extra
8585 argument on variable argument list. The argument type must
8586 now be provided to the function. Also, added new function:
8587 silc_command_encode_reply_payload_va which is same as
8588 normal command_encode_payload_va except command status type
8589 is provided as extra argument.
8591 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8593 * Added ~./silc directory handling. The directory includes the
8594 public and private keys for the client.
8596 Added silc_client_check_silc_dir, silc_client_create_identifier
8597 and silc_client_load_keys.
8599 * Implemented SILC protocol compliant public key. Added public
8600 and private key saving to and loading from files.
8602 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
8603 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
8604 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
8605 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
8606 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
8608 Implemented: silc_pkcs_save_[public/private]_key[_data] and
8609 silc_pkcs_load_[public/private]_key.
8611 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8613 * Added silc_server_get_route (route.[ch]) to get connection
8614 data for the fastest route for given ID.
8616 * Implemented INVITE command on client and server. The command
8617 were re-defined in the SILC Protocol Specification and the
8618 implementation now complies with the specification.
8620 * Implemented PING command on client and server.
8622 * Implemented NAMES command on client and server. The server side
8623 supports currently only normal server not router server yet.
8624 Some changes to NAMES definition in SILC protocol specification.
8626 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8628 * Implemented LEAVE command on client and server.
8630 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
8631 again. This change was made to the protocol as well. Server
8632 should not violate the protocol specification anymore.
8634 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8636 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
8637 was tested. SOCKS4 was not but should work anyway.
