3 * Added silc_client_udpate_server function to update changed
4 server info. Affected file lib/silcclient/idlist.[ch].
6 * Added check for server entries that are being resolved when
7 notify is received. If being resolved, handle the received
8 notify only after it's resolved so that all notifys are
9 handled in same order as received from the server.
11 Added similar resolver check to channel entries. Every
12 notify that cause resolving of any information that affects
13 channel entry marks the channel entry in waiting state.
14 After whatever resolving is over the waiters are signalled
15 and only then the notifys are handled in the same order
16 as delivered from the server.
18 Affected files are lib/silcclient/idlist.[ch], and
21 * Fixed KILLED notify handling in normal server. Affected
22 file silcd/packet_receive.c.
24 * Added SILC_IDLIST_STATUS_LOCAL which indicates that entry
25 is locally connected, or was locally connected (but may
26 be detached and connection is not active). Added also
27 SILC_IS_LOCAL for checking this status. Affected files
28 silcd/idlist.h, silcd/packet_receive.c, silcd/server_util.c,
29 silcd/server.c and silcd/server_internal.h.
31 Sat Jun 22 17:06:58 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
33 * Don't send or handle TOPIC_SET if topic is already set and
34 is same as being set. Affected files silcd/command.c and
35 silcd/packet_receive.c.
37 * Fixed CMODE change rights checking to work correctly when
38 removing modes by operator. Affected file is
41 * Fixed some handling with New Channel packet in router and
42 fixed some CMODE_CHANGE notify handling in server and router.
43 Affected file is silcd/packet_receive.c.
45 * Changed "disconnect" client operation to include the
46 reason of the disconnection and optional disconnection
47 message. Affected file lib/silcclient/silcclient.h.

54 * All CMODE_CHANGE and CUMODE_CHANGE notifys are now sent back
55 to the sender of the notify too, to avoid situation where two
56 notifys are in the network at the same time going to oppsite
57 directions. Affected file silcd/packet_receice.c.
59 Fri Jun 21 10:00:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
61 * Delete the client from channel even if the cilent->id is
62 NULL. It was possible that client was deleted without
63 removing from channels (theoretically at least). Affected
64 file silcd/server.c and silcd/server_util.c.
66 * Free the client data too when resuming is not successful.
67 Affected file silcd/packet_receive.c.
69 * Merged some code from c0ffee's silc-plugin. Affected files
70 irssi/src/silc/core/silc-channels.c and silc-expandos.c.
72 * Added SILC_PRIMARY_ROUTE and SILC_BROADXAST macros to
73 silcd/server_internal.h. SILC_PRIMARY_ROUTE Returns pointer
74 to the primary router connection, the other one returns
75 TRUE if packet must be broadcasted to network.
77 * All notifys that are destined to primary router (to network)
78 are now automatically sent to backup routers even if the
79 router is standalone (and has backup router). Affected files
82 * Added --without-irssi and --without-silcd configuration
83 options for disabling the compilation of these applications.
84 Affected file configure.in.pre and prepare.

110 command reply from router, on normal server. Otherwise
111 joinig +a channels from normal server is not possible.
112 Affected file silcd/command.c.
114 * Fixed a bug in TOPIC_SET notify handling. The notifier
115 may be other than client too, like server or channel.
116 It expected it to always be only client and ignored the
117 notify. Affected file silcd/packet_recieve.c.
119 * Removed some (unnecessary) debug printing from
120 lib/silccore/silcid.c and lib/silccore/silcargument.c.
122 * Do not force CMODE_CHANGE when server is announcing new
125 Router announces stuff only after server reannounces channel
126 after CHANNEL_CHANGE notify.
128 These fixes optimizes the announcing procedure, and perhaps
129 fixes some problems too. Affected file silcd/packet_receive.c.
131 * Fixed SERVER_SIGNOFF sending to local clients. It was
132 totally broken and sent the notify to all local clients,
133 instead of only to those that was on same channel as the
134 signing off clients. Affected file silcd/server_util.c.
136 * Added -D option to server. It can be used to give debug
137 level. The levels are from 0 - 99, and are predefined for
138 smooth server debugging. (see silcd.c for the predefined
139 levels). Affected file silcd/server.c.
141 Wed Jun 19 16:01:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

605 Tue Apr 16 09:34:40 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
607 * Defined that channel message to unknown Channel ID must
608 cause SILC_NOTIFY_TYPE_ERROR notify message to the sender.
609 Updated the protocol specs and the code in server. The
610 affected file is silcd/packet_receive.c.
612 Mon Apr 15 19:57:57 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
614 * Added new notify type SILC_NOTIFY_TYPE_ERROR and specified
615 that it is used to send error notifys if error occurs during
616 some SILC packet processing, except commands. The error
617 types are same as for command reply types. Defined that
618 if private message is sent to unknown Client ID the error
619 is sent in SILC_NOTIFY_TYPE_ERROR instead of command reply.
620 Updated the protocol specs and code. Affected files are
621 lib/silccore/silcnotify.h, added lib/silccore/silcstatus.h,
622 lib/silcclient/client_notify.c, silcd/packet_receive.c,

627 The <Requested Attributes> (defined in a separate document)
628 can be used to request additional information about user
629 not returned by standard WHOIS command. Defined that server
630 can send WHOIS command directly to client. Client provides
631 the requested attributes to the server. Updated the protocol
632 specs. Protocol TODO #4. Implementation is not done yet
635 * Renamed function silc_client_command_status_message to
636 silc_client_status_message. Affected files are

662 another command may attach to the same pending command reply
663 without requiring to resolve the same entry again. Added
664 support for adding multiple pending commands for one
665 command idenfier. Affected files lib/silcclient/command.[ch],
666 lib/silcclient/command_reply.[ch], lib/silcclient/idlist.h.

671 and secret channels too. Updated protocol specs and the
672 code in server. Affected file silcd/command.c.
674 * Defined <channel user mode list> argument to WHOIS command
675 reply for returning user modes on the channels. The
676 channel list now doesn't include the user mode anymore but the
677 actual channel mode. Updated protocol specs and the code in
678 client and server. Affected files are silcd/command_reply.c,
679 silcd/command.c, silcd/server.c, irssi/src/silc/core/client_ops.c,

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

697 mask to the client. Updated protocol specs and the server.
698 Affected file is silcd/command.c.
700 * Added SILC session detachment/resuming support. It is possible
701 to detach by closing the network connection and then re-connect
702 and resume to the old client session. Added DETACHED user
703 mode that server will set for detached client. Added new
704 packet RESUME_CLIENT which is used to perform the resuming
705 process. Added DETACH command. Updated the protocol specs,

713 mask to the client. Updated protocol specs and the server.
714 Affected file is silcd/command.c.
716 * Changed the Killer's Client ID in KILLED notify to be just
717 any ID payload since router server is allowed to kill as well.
718 Updated protocol specs, client libary and server. Affected
719 files are lib/silcclient/client_notify.c, silcd/packet_receive.c,
720 and irssi/src/silc/core/client_ops.c.

724 * Added new user modes ANONYMOUS for special anonymous servers
725 that may set the mode for client, and BLOCK_PRIVMSG which
726 client may set to block incoming private messages unless the
727 Private Message Key flag is set (using private keys to protect
728 private messages). Updated protocol specs and code in client
729 and server and core library. Protocol TODO #23. Affected
730 files are lib/silccore/silcmode.h, silcd/server.[ch],

735 may set to itself to tell server not send channel messages.
736 Other packets such as channel key packets are still sent.
737 Protocol TODO #23. Updated the protocol specs, client and
738 server. Affected files are lib/silccore/silcmode.h,
739 irssi/docs/help/in/cumode.in, lib/silcclient/command.c,
740 lib/silcutil/silcutil.c, silcd/command.c, and
743 Mon Apr 8 23:57:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
745 * Redefined the Status Payload to include now two 8 bit fields,
746 instead of one 16 bit field. This now makes it possible to
747 send list of errors. Updated the protocol specs and the code
748 in core library, client library and server. Protocol TODO #1.
749 Affected files are lib/silccore/silccommand.[ch],
750 lib/silcclient/command_reply.[ch], silcd/command.c,
751 silcd/command_reply.c and silcd/packet_receive.[ch].
753 Mon Apr 8 19:57:40 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
755 * Added config parse status SILC_CONFIG_EPRINTLINE, this status
756 must be handled by the application and should tell the application
757 that an error message was already printed, and it should print the
758 config coords (line, filename, ...). Affected files are
759 silcd/serverconfig.c, lib/silcutil/silcconfig.[ch].
761 * Added local macro SILC_SERVER_CONFIG_ALLOCTMP to make the
762 server config parsing code more readable.

777 lib/silccore/silcmode.h, irssi/src/silc/core/client_ops.c,
778 irssi/docs/help/in/umode.in and lib/silcclient/command.c.
780 Sun Apr 7 17:07:59 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
782 * Added STATS command to the protocol after all, to return
783 various statistical information about the network. It can
784 be used by clients to retrieve statistical information, and
785 servers may use it to to fetch cell and network wide
786 statistics from router. Updated the protocol specs and
787 implemented it to the server. Protocol TODO #16.
788 Affected files are lib/silccore/silccommand, silcd/command.[ch],
789 silcd/command_reply.[ch].
791 Sat Apr 6 17:08:58 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
793 * The LIST command reply in client libary now adds new channel
794 entry if the returned channel doesn't exist yet in cache,
795 and returns the channel entry to the application in the
796 command_reply client operation. Affected file is
797 lib/silcclient/command_reply.c.
799 * Changed the channel message payload's MAC generation to
800 include the IV in the MAC as well. This way all relevant
801 parts of the channel message payload are authenticated also
802 with the channel message MAC (and not only by packet MAC).
803 Causes incompatibility with 1.0 protocol. Protocol TODO #7.
804 Affected file is lib/silccore/silcchannel.c.
806 * Fixed the SKE to save the remote version, since the
807 silc_ske_parse_version mistakenly checked wrong version,
808 after it replaced the start payload. Affected files are
809 lib/silcske/silcske.[ch].
811 Fri Apr 5 16:03:03 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

818 * Renamed silc_*_pem functions to silc_pem_* functions. Affected
819 files are lib/silcutil/silcstrutil.[ch].
821 * Defined that the security property fields in SKE SHOULD be
822 UTF-8 encoded, defined that version string MUST be US-ASCII
823 encoded, defined that passphrases sent in connection
824 authentication protocol MUST be UTF-8 encoded. Implemented
825 these to the client and server. Defined also that other
826 passphrases sent in the protocol MUST be UTF-8 encoded.
827 Affected files are lib/silcske/silcske.c,
828 lib/silcclient/protocol.c, silcd/protocol.c,
829 silcd/serverconfig.c, and lib/silccore/silcauth.c.
831 * Changed the silc_client_close_connection interface to not
832 need the SilcSocketConnection which should not be visible
833 to application. Affected files are lib/silcclient/client.c
834 and lib/silcclient/silcclient.h.
836 * Rewrote the text for Private Message Key Payload in the
837 protocol specification. Protocol TODO #11.
839 Wed Apr 3 16:24:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
841 * Upgraded the protocol version to 1.1, updated protocol specs
844 * Added the nickname as new argument to NICK_CHANGE notify and
845 added it to protocol specs and implemented it to client and
846 server. Protocol TODO #3. Affected files are silcd/idlist.[ch],
847 silcd/command.c, silcd/packet_receive.c, packet_send.[ch], and
848 lib/silcclient/client_notify.c.

855 The killer's client entry is now returned to application in
856 the `notify' client operation.
858 * Fixed the Max Argument fields that had too large value set
859 in the protocol specs. Protocol TODO #14.
861 * Added the LEAVE command reply to return the ID of parted
862 channel. Updated protocol specs and implemented it to the
863 client and server. Protocol TODO #15. Affected files are
864 silcd/command.c, lib/silcclient/command_reply.c. The channel
865 entry is now returned to application in the `command_reply'

869 and in server to use the silc_parse_version_string. Affected
870 files are lib/silcclient/protocol.c, silcd/protocol.c.
872 * Added SILC_STATUS_ERR_NO_CHANNEL_FOPRIV error status to few
873 commands that was missing it, and updated protocol specs and
874 the server implementation. Protocol TODO #10. The affected
875 file is silcd/command.c.
877 * Defined new message flags SILC_MESSAGE_FLAG_REPLY to be
878 generic reply to a generic request (REQUEST flag), and
879 SILC_MESSAGE_FLAG_DATA to send any kind of data in a generic
880 way. A draft-riikonen-silc-flags-payloads-00.txt is written
881 to define the payload for DATA flag. Added the flags to
882 the implementation. Protocol TODO #9. Affected file is
883 lib/silccore/silcchannel.h.
885 Changed the client library to return the message length
886 to application as well in the channel_message and private_message
887 client operations. Affected files are

890 and lib/silcclient/client_ops_example.c.
892 * Added two new channel modes: SILC_CMODE_SILENCE_USERS
893 and SILC_CMODE_SILENCE_OPERS which can be used to moderate
894 the channel. Updated protocol specs and impelemented this
895 to client and server. Protocol TODO #6. Affected files are
896 silcd/packet_receive.c, server_util.c, lib/silcclient/command.c,

899 Added new options m and M to CMODE command in Irssi SILC
900 client to set these modes.
902 * Deprecated all administrative commands from SILC protocol
903 since they are highly implementation specific commands.
904 Updated protocol specs. Moved the old commands in
905 implementations to private range of command types. Affected
906 files are silcd/command.c, lib/silcclient/command.c and
907 lib/silcclient/command_reply.c. Protocol TODO #8.

925 Affected file silcd/protocol.c.
927 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
929 * Some client implementations quit network by doing first LEAVE
930 and then immediately SIGNOFF (like Bombyx). We now do check
931 after a short time after LEAVE notify and check whether the
932 client is still valid after LEAVE, and if not we remove it from
933 cache. Affected file is lib/silcclient/client_notify.c.
935 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
937 * Merged version 1.1.4 of zlib. Even if it not currently in use,
938 it's good not to have security holes here.
940 * Fixed a negative refcount situtuation for the config context.
941 Affected file is silcd/serverconfig.c.
943 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>

959 silc_hash_register, silc_hmac_register and silc_pkcs_register
960 to const. Affected files are lib/silccrypt/silccipher.[ch],
961 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
963 * Changed the silc_get_username and silc_get_real_name to
964 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
966 * Fixed the Irssi SILC Client to use the silc_get_username and
967 silc_get_real_name insted of glib routines since the glib
968 routines only corrupt stack. Fixes the Irssi SILC to work in
969 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
971 * Fixed the Irssi to not use g_get_home_dir since it crashes
972 or returns garbage on cygwin and corrupts stack. Added function
973 get_home_dir to Irssi routines. Affected files are
974 irssi/src/core/misc.[ch] and irssi/src/core/core.c.

978 * Made some structure optimizations. SFTP memory FS MemFSEntry
979 entry structure. Optimized SilcTask structure. Optimized
980 SilcPacketContext structure.
982 Affected files lib/silcsftp/sftp_fs_memory.c,
983 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
985 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
987 * And yet again reverted back the config thing since Johnny
988 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
991 * Fixed memory leaks from config object. Affected files are
992 silcd/serverconfig.[ch].
994 * Added support for adding new connections to the server in rehash.
995 After rehash they take effect.
997 Added support for changing the maximum allowed connections in
998 rehash. The number can grow but going smaller is not supported.
1000 Added function silc_server_num_sockets_by_remote to the
1001 silcd/server_util.[ch].
1003 Affected files are silcd/server.c, and silcd/serverconfig.[ch].

1008 public/private key and removed further checks in the code.
1009 Affected files are silcd/serverconfig.[ch], server.c.
1011 * Moved functions silc_server_drop() and silc_server_daemonise()
1012 from server.c to silcd.c since they are stricly related to
1013 the application activity.
1015 * Reverted a small part of the automatic ref/unref since
1016 it caused a double unref in some situations. Affected
1017 files are silcd/silcd.[ch], server.c, serverconfig.c.

1023 * Fixed silc_net_gethostbyaddr to correctly resolve by
1024 address. Affected file lib/silcutil/silcnet.c.
1026 * Fixed the notify relaying to client. The HMAC to be used
1027 with relayed packets ws wrong and caused decryption failure
1028 at the client end. Affected file is silcd/packet_receive.c.
1030 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1032 * Created new branch silc_protocol_1_0_branch.
1034 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
1036 * Changed the silc_server_config_* routines to be SilcServer
1037 independent. They are now officially application specific code
1038 and not part of generic server implementation. Affected files
1039 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
1041 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1048 * Fixed the silc_log_quick handling in the logging routines.
1049 It didn't log quickly when it was TRUE. Affected file is
1050 lib/silcutil/silclog.c. Also the flush delay was set even
1051 if it was 0 in config file. Affected file is
1052 silcd/serverconfig.c.
1054 * Added support for changing key pair of the server in rehash.
1055 Affected file silcd/server.c.
1057 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1059 * Fixed the TOPIC_SET notify to not cras. It changed the topic
1060 too early, before getting the channel entry. Affected file
1061 is silcd/packet_receive.c.
1063 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1065 * Added functions silc_server_config_[ref/unref], these are used
1066 to prevent that the config object is destroyed.
1068 No longer directly affect global variables silc_log_quick and
1069 silc_log_delay, they are first cached inside the config object
1070 and then applied with silc_server_config_setlogfiles().
1072 silc_server_config_set_defaults() is now internal to
1073 serverconfig.c, there are no reasons to show this internal stuff
1076 Affected files are silcd/serverconfig.[ch].
1078 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
1079 fprintf's to stderr, since some code may be executed again after
1080 the server went into the background. Affected files are
1083 * Added rehash support. Added function silc_server_rehash() that
1084 will perform all the basic tasks of the rehashing procedure.
1086 * Added command line option `-x, --hexdump'. This will enable the
1087 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
1088 The option `--hexdump' implies `--debug'.
1090 * Fixed a bad bug in the logging APIs (silcutil library) where
1091 the application would crash after calling silc_log_reset_all().
1093 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1095 * Fixed the KICKED notify handling in client library to
1096 correctly remove the channel and all entries from the
1097 channel when I was kicked. This bug crashed the client.
1099 Fixed yet another but in KICKED notify handling to remove
1100 the kicked client correctly from the channel.
1102 Affected file is lib/silcclient/client_notify.c.
1104 * Fixed a minor bug in looking up correct client entry
1105 in KICKED notify in server. Affected file is
1106 silcd/packet_receive.c.
1108 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
1109 sources correctly to distribution. Fixes --with-gmp option.
1111 * Removed the manual rehashing from ID Cache, and changed it
1112 to use the SILC Hash Table's auto rehash feature. Affected
1113 file is lib/silccore/silcidcache.c.
1115 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1117 * Fixed a bug in the silc_client_nickname_format function that
1118 handles the multiple same nickname formatting. Two clients
1119 with same nickname caused problems after the first one left
1120 and rejoined. It didn't format the nickname correctly.
1121 Affected file is lib/silcclient/idlist.c.
1123 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1125 * Don't change the topic if olod topic is same as new one.
1126 Affected file is silcd/packet_receive.c.
1128 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1130 * Added cross-reference support to the SILC Documentation
1131 generator. All types across all HTML files are now cross-
1132 referenced. Affected files util/robodoc/generator.c and
1133 scripts/silcdoc/silcdoc.
1135 * Added file lib/silcutil/silctypes.h to include all the
1136 arithmetic type definitions and some macros. Removed
1137 includes/bitmove.h and moved macros to silctypes.h.
1139 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1141 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
1143 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1145 * Added `type' argument to silc_id_payload_parse_id function which
1146 now returns the type of the ID to the sent pointer. Affected
1147 file is lib/silccore/silcid.[ch].
1149 * Added check for CMODE_CHANGE notify type that mode change is
1150 allowed by the sender. Affected file silcd/packet_receive.c.
1152 * Added check for CUMODE_CHANGE notify type that mode change is
1153 allowed by the sender. Affected file silcd/packet_receive.c.
1154 Added the ID type as CUMODE_CHANGE notify type as argument
1155 to the `notify' client operation. Affected files are
1156 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
1158 * Added function silc_client_add_server to the client library.
1159 Added support for resolving also channel and server info when
1160 received unknown entity in notify packet. Affected files are
1161 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
1163 * Added function silc_command_get_status to return the command
1164 status from the command reply's argument payload. Affected files
1165 are lib/silccore/silccommand.[ch].
1167 * Added check for KICKED notify type that the kicking is
1168 allowed by the client. Affected file silcd/packet_receive.c.
1170 * Created function silc_get_input which can be used to get input
1171 (echo on or off) from user on command line. Affected files are
1172 lib/silcutil/silcutil.[ch].
1174 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1176 * Optimized silc_server_packet_relay_to_channel function.
1177 Added new function silc_channel_message_payload_encrypt which
1178 can be called directly if channel message payload needs to
1179 be encrypted and is already encoded (no need to call _encode
1180 function). Packet relaying is now done by router without any
1181 extra memory allocations. Affected files are
1182 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
1183 silcd/packet_send.c.
1185 * Fixed the INVITE notify handling. It took wrong arguments
1186 as invite list and invite delete. Affected file is
1187 silcd/packet_receive.c.
1189 * Added check for TOPIC_SET notify type that the topic change is
1190 allowed by the client. Affected file silcd/packet_receive.c.
1192 * Added check for INVITE notify type that inviting is allowed by
1193 the client. Affected file silcd/packet_receive.c.
1195 * Changed the silc_server_client_on_channel to return the
1196 SilcChannelClientEntry as well. Moved the function
1197 silc_server_check_cmode_rights to server_util.[ch].
1198 Affected files are silcd/server_util.[ch], silcd/command.c.
1200 * Added function silc_server_check_umode_rights to check whether
1201 changing client's user mode is allowed. Added check for
1202 UMODE_CHANGE notify type that the umode change is allowed
1203 by the client. Affected files are silcd/server_util.[ch],
1204 silcd/packet_receive.c and silcd/command.c.
1206 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1208 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
1209 ID length. It ignored that ID can be IPv6 based as well.
1210 Affected file lib/silccore/silcpacket.h.
1212 * Fixed the silc_id_id2str and silc_id_str2id to take the
1213 IPv6 address offset's into consideration. Affecte file is
1214 lib/silccore/silcid.c.
1216 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1218 * Fixed the internal Unix scheduler functions to check for
1219 NULL context they may receive. The affected file is
1220 lib/silcutil/unix/silcunixschedule.c.
1222 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
1224 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
1225 can specify different directory with --home command line
1226 parameter. Affected files irssi/src/silc/core/client_ops.c,
1229 * SILC-specific commands aren't now executed if the active server
1230 isn't of SILC-type, so there won't be problems with having
1231 IRC and SILC protocol support in same client. Affected files
1232 irssi/src/silc/core/silc-channels.c, silc-servers.c,
1235 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1237 * Improved the signal support in SILC Schedule. Added new
1238 function silc_schedule_signal_call which is used by application
1239 to mark a signal to be called. It is now safe to perform
1240 any kind of tasks in signal callbacks since it is guaranteed
1241 that the application specified signal callback is called
1242 after the signal is over. Affected files are
1243 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
1245 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1247 * Added `name' field to SilcChannelPrivateKey to represent
1248 application given name for the key. Moved also the context from
1249 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
1250 Added the `name' argument also to the function
1251 silc_client_add_channel_private_key.
1253 Added function silc_client_current_channel_private_key to set the
1254 current channel private key in use.
1256 Added "change" command to KEY command which can be used to change
1257 the current channel private key. Bound the command also to
1258 alt+K (Alt+Shift+k).
1260 Also affected files lib/silcclient/client_channel.c,
1261 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
1263 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1265 * Added silc_rng_get_byte_fast function in to the
1266 lib/silccrypt/silcrng.[ch].
1268 * Changed the interface of silc_packet_assemble and the
1269 silc_packet_send_prepare. If silc_packet_assmble is now
1270 called the application does not call silc_packet_send_prepare
1271 because the library will call it automatically. These
1272 interfaces now also return a reference to the outgoing buffer
1273 which includes the assembled packet, which the application can
1274 use to encrypt the packet.
1276 Affected files are lib/silccore/silcpacket.[ch],
1277 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
1278 silcd/packet_send.c, server_backup.c and packet_receive.c.
1280 * Fixed a packet sending bug on very high load, where outgoing
1281 packet queue wasn't handled correctly and packets got corrupted.
1282 Affected files are lib/silcutil/*/silc*sockconn.c,
1283 lib/silcclient/client.c and silcd/server.c.
1285 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1287 * Added macro SILC_PACKET_DATALEN which can be used during
1288 packet assembling to check whether the data to be added to
1289 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
1290 len is truncated until it fits it.
1292 Added checks for maximum length of channel message payload and
1293 private message payload also.
1295 Added checks for maximum packet length in server and in
1298 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
1299 lib/silcclient/client.c, lib/silccore/silcchannel.c and
1300 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
1301 lib/silcclient/client_prvmsg.c.
1303 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1305 * Added silc_server_packet_queue_purge call to the
1306 silc_server_disconnect_remote to assure that all data in the
1307 queue before disconnecting is sent to the network. Affected
1308 file silcd/server.c.
1310 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1312 * Added the deleting of server's own ID cache entry to the
1313 silc_server_free function. Free also everything else that
1314 has been allocated in silc_server_init. The affected file
1317 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1319 * Added functions silc_parse_version_string, silc_version_to_num,
1320 and silc_ske_parse_version to parse SILC protocol style version
1321 strings. Affected files lib/silcutil/silcutil.[ch] and
1322 lib/silcske/silcske.[ch].
1324 * Added new configuration params: version_protocol, version_software
1325 and version_software_vendor to specify what version the remote
1326 host must at least be to be able to connect to server. The vendor
1327 string can be regex matched too. Added new function
1328 silc_server_connection_allowed to check maximum number of allowed
1329 connections, and allowed versions for incoming connections.
1330 Affected files are silcd/server.c, server_util.[ch] and
1333 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1335 * Added preliminary support for signals in scheduler. The
1336 signals we care about are now blocked always when the scheduler
1337 is locked. This way we can synchronise the use of signal with
1338 scheduler. It is guaranteed that when signal occurs the scheduler
1339 is not locked, and thus new tasks can be safely added to the
1342 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
1343 to silc_schedule_internal_init and silc_schedule_internal_uninit.
1344 Added new platform specific routines
1345 silc_schedule_internal_signals_[un]block and
1346 silc_schedule_internal_signal_[un]register.
1348 Added new functions to SILC Schedule API:
1349 silc_schedule_signal_[un]register. Each signal that application
1350 is going to use should be registered to the scheduler.
1352 Affected files are lib/silcutil/silcschedule.[ch],
1353 lib/silcutil/*/silc*schedule.c.
1355 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1357 * Check for unauthenticated client and server in the
1358 silc_server_new_client and silc_server_new_server functions.
1359 Affected file silcd/packet_receive.c.
1361 * Added function silc_string_is_ascii to check whether given
1362 string is 7-bit ASCII string. Affected files are
1363 lib/silcutil/silcutil.[ch].
1365 * Added function silc_id_is_valid_server_id into the
1366 silcd/serverid.c and added checking for valid Server ID's in
1367 silc_server_new_server. The Server ID must always be based
1368 on the server's public IP address.
1370 * Added logging of DISCONNECT packet message in the server.
1371 Affected file silcd/server.c.
1373 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1375 * Changed all library interfaces that use Global RNG to also
1376 accept SilcRng as argument. Affected files are
1377 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
1378 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
1379 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
1380 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
1381 lib/silccrypt/rsa.c.
1383 * Added function silc_pkcs_generate_key to the
1384 lib/silccrypt/silcpkcs.[ch] for applications so that they
1385 don't need to do pkcs->pkcs->init calls anymore.
1387 * Remove SilcSocketConnection from the SFTP API since it really
1388 wasn't needed there. The application has the information
1389 saved in its contexts anyway and the SFTP layer doesn't need
1390 know about it. Affected files lib/silcsft/silcsftp.h and
1391 lib/silcsftp/sftp_[server/client].c.
1393 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
1394 The SilcSimContext is not SilcSim.
1396 * Fixed possible buffer overflows in silc_id_render in the
1397 lib/silcutil/silcutil.c.
1399 * On EPOC the global crypto module lists are not used at all
1400 in the crypto library. Added support for using the constant
1401 algorithm list on EPOC. Affected files are
1402 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
1405 * Fixed the handling of third parameter of KICKED notify, since
1406 it was mistakenly updated to SILC Protocol 1.0 even though it
1407 is to be included in 1.1. Since it is not in 1.0 it is not
1408 mandatory, and this fix now handles it only if it is provided,
1409 and it is not error if it is not provided. Affected file
1410 lib/silcclient/client_notify.c.
1412 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1414 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
1415 client. Affected file irssi/src/silc/core/client_ops.c.
1417 * Merged with Irssi 0.8.4 from irssi.org CVS.
1419 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1421 * Check for valid socket connection in client entries before
1422 sending any messages. Fixes a crash, but doesn't fix some
1423 other underlaying bug that is lurking there. Affected
1424 file silcd/packet_send.c.
1426 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
1428 * $usermode, $cumode and $cumode_space expandos shouldn't do
1429 anything with non-SILC server records. Affected file
1430 irssi/src/silc/core/silc-expandos.c
1432 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1434 * Fixed the silc_net_check_[host/local]_by_sock to support
1435 IPv6 bound sockets as well. Now they can return IPv6 addresses
1436 as well. Affected file lib/silcutil/silcnet.c.
1438 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
1439 Affected lib/silcutil/unix/silcunixnet.c.
1441 * Fixed ID rendering (at least on some platforms, not NetBSD)
1442 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
1444 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1446 * Added silc_hash_public_key and silc_hash_public_key_compare
1447 functions to be used with SilcHashTable. They can be used to
1448 hash public keys and compare public keys in hash table. Affected
1449 file lib/silcutil/silcutil.[ch].
1451 * Added support for specifying multiple public keys for Client
1452 connection section in server configuration file. This makes it
1453 possible to accept multiple public keys from same host, or to
1454 make a section that accepts any incoming host, and have the
1455 accepted public keys listed in the section.
1457 Added functions silc_sever_[find/get]_public_key, added the
1458 support for this actually to all connection sections but only
1459 the Client section is currently allowed to specify multiple
1462 Affected files are silcd/server.c, server_internal.h,
1463 command.c, protocol.c, server_util.[ch], packet_receive.c.
1465 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1467 * Merged Irssi 0.8.2 from irssi.org CVS.
1469 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1471 * If silc_debug is TRUE, also output standard logging messages
1472 to stderr with the debug output.
1474 Made silc_log_reset_all() flushing all channels before returning.
1475 Also fixed some documentation typos.
1477 Affected files are lib/silcutil/silclog.[ch].
1479 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1481 * Fixed the server to check correctly the amount of connections
1482 from single host, by checking also the type of the connection.
1483 Fixed also the comparison of number of connections and number
1484 of allowed connections. Affected files are silcd/server.c,
1487 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1489 * Fixed the USERS command reply to save the user's mode on the
1490 channel as well. Fixed JOIN command reply to check whether a
1491 client is on channel already and not join it twice. Affected
1492 file lib/silcclient/command_reply.c.
1494 * Added new file silc-expandos.c into irssi/silc/core/ to return
1495 various stuff for various signal for the statusbar etc. updating.
1496 Now Irssi SILC client prints channel user modes etc. on the
1499 * The user mode (like server/router operator changes) is now shown
1500 on the Irssi SILC client's statusbar. The affected files are
1501 irssi/src/silc/core/client_ops.c, silc-expandos.c.
1503 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1505 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
1506 to SILC_SCHEDULE_[UN]LOCK macros.
1508 * Added more error printing to logs in server code. Affected
1509 files silcd/server.c and silcd/protocol.c.
1511 * Fixed -S option parsing in Irssi SILC Client. Affected file
1512 irssi/src/silc/core/silc-core.c.
1514 * Added silc_buffer_alloc_size function. Affected file is
1515 lib/silcutil/silcbuffer.h.
1517 Tue Mar 5 14:37:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1519 * Changed all silc_[hash|hmac|cipher|pkcs]_default tables to
1520 constants. Affected files in
1521 lib/silccrypt/silcpkcs.[ch], silchash.[ch], silchmac.[ch] and
1524 * Changed the internal SFTP Memory FS table to const. Affected
1525 file lib/silcsftp/sftp_fs_memory.c.
1527 Sun Mar 3 18:37:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1529 * Fixed the buffer formatting and unformatting routines to
1530 check the size of 64 bits types with sizeof(). Affected
1531 file is lib/silcutil/silcbuffmt.c.
1533 Mon Feb 25 17:19:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1535 * Removed 0.6.x backwards support.
1537 Sun Feb 24 12:53:25 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1539 * Changed all integer type names:
1540 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
1541 to avoid collisions with other libraries using same type names
1544 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1546 * Added `prefer_ipv6' argument to the functions
1547 silc_net_gethostbyname[_async]. If it is TRUE it will return
1548 IPv6 address over IPv4. If FALSE IPv4 address is returned
1549 even if IPv6 address was found. Affected files
1550 lib/silcutil/silcnet.[ch].
1552 * Added support silc_net_create_connection[_async] to fallback
1553 to IPv4 address if IPv6 address could not be used (like if

1566 application does not need to define them. Affected file
1567 includes/silcincludes.h.
1569 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
1570 old name went against naming convention. Applications now
1571 include "silcclient.h" instead of "clientlibincludes.h".
1572 Removed includes/clientlibincludes.h, it is redundant now.
1574 * Renamed includes/version.h to silcversion.h.
1576 * Added really preliminary support for OS/2 into the util

1634 the SKE interface a bit.
1636 * Fixed padding problem in PKCS#1. The padding was not actually
1637 random since the random number generator was used incorrectly.
1638 This security bug affects only when encrypting with PKCS#1, and
1639 it is not currently used at all in SILC. SILC only use signing
1640 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.

1725 the connection configuration object from the SilcServerConnection
1726 object instead of finding it during the connecting phase.
1727 Added the configuration object to SilcServerConnection struct.
1728 Affected files silcd/server_internal.h, server.c.
1730 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1732 * Add the client on channel after it was resolved at the
1733 channel message receiving, and it was not already on the
1734 channel. Affected file lib/silcclient/client_channel.c.

1754 Added `prefer_passphrase_auth' setting in config file which
1755 can be used to set to prefer passwd auth if both passwd and
1756 public key is set. If not set, public key is preferred.
1757 This has effect only when being initiator (responder will try
1760 Added support for authentication with passphrase and public key
1761 at the same time. The passphrase is tried first always since
1762 it is faster to check.
1764 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
1766 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

1813 zero port also if the hostname is NULL because it could not
1816 Call file transfer monitor callback now also if error occurs
1817 during key agreement protocol.
1819 Changed the silc_client_file_send interface to return the
1820 SilcClientFileError instead of session id. The session ID
1821 is returned into pointer provided as argument.

1893 * Fixed a bug in hash table tarversing. While the hash table
1894 is traversed with SilcHashTableList the table must not be
1895 rehashed. It is now guaranteed that auto rehashable tables
1896 are not rehashed while tarversing the list. Also defined that
1897 silc_hash_table_rehash must not be called while tarversing
1898 the table. Added function silc_hash_table_list_reset that must
1899 be called after the tarversing is over. The affected files are
1900 lib/silcutil/silchashtable.[ch].
1902 * Changed all hash table traversing to call the new
1903 silc_hash_table_list_reset in server and in client library.
1905 * Added function silc_client_on_channel to return the
1906 SilcChannelUser entry if the specified client entry is joined

1917 lists correctly. Affected file silcd/command.c.
1919 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1921 * When sending JOIN command to router for processing the
1922 sender's old command identifier was not saved back to the
1923 sender's command context, fixed now. The affected file is
1926 * Create the key in JOIN command of the router did not return
1927 the channel key, added check for this. Affected file is
1930 * Fixed a channel ID update bug in JOIN command reply. Do
1931 not directly upgrade the ID but call the function

2084 * Added `sock_error' field into the SilcSocketConnection
2085 context. When error occurs during socket operation (read
2086 or write) the error is saved. Added also new function
2087 silc_socket_get_error to return human readable socket error
2088 message. Affected files are lib/silcutil/silcsockconn.[ch],
2089 lib/silcutil/unix/silcunixsockconn.c, and
2090 lib/silcutil/win32/silcwin32sockconn.c.
2092 * The server now prints the socket error message in the
2093 signoff for client. Affected file silcd/server.c.
2095 * Fixed the `created' channel information sending from router
2096 to server in JOIN command. Checks now whether the channel
2097 really was created or not and set it according that.
2099 Fixed the JOIN command to use the client entry's current
2100 ID during the joining procedure instead of the one it sent
2101 in the command (it is checked though), since it can change
2102 between the packet processing and command processing, and
2103 would just case unnecessary pain in the client end. Affected
2104 file silcd/command.c.
2106 * Fixed a channel key payload sending to use correct channel
2107 ID when the server was forced to change the channel's ID by
2108 router. Router sent the key payload with the old Channel ID.
2109 Affected file silcd/packet_receive.c.
2111 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2113 * Call silc_server_save_channel_key only if the key payload
2114 was provided in the JOIN command's command reply. Affected
2115 file silcd/command_reply.c.
2117 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2119 * Fixed silc_mp_sizeinbase to return the value correctly with
2120 MPI. Affected file lib/silcmath/mp_mpi.c.
2122 * Fixed the stop_server signal to correctly stop the scheduler
2123 and gracefully stop the server when SIGTERM or SIGINT signals
2124 are received. Affected file silcd/silcd.c.
2126 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
2128 * Simple handling of TERM and HUP signals. Also added some log
2129 flushing call around. Affected file is
2132 * Fixed small bugs in silclog.c. Now buffering output will take
2133 effect after 10 seconds since startup: This will ensure that
2134 no important startup messages are lost. Also output redirection
2135 will preserve original format ([Date] [Type] message).
2136 Affected file is lib/silcutil/silclog.c.
2138 * Added two options to the config file, in the logging section:
2139 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
2140 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
2142 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2144 * Do not print the warning about log files not being initialized
2145 more than once to avoid excess logging. Affected file is
2146 lib/silcutil/silclog.c.
2148 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
2149 the SIM copying in make install in Makefile.am.pre.
2151 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2153 * Rewritten silclog APIs. Globally interesting changes follows:
2154 silc_log_set_files() changed to silc_log_set_file().
2155 silc_log_set_callbacks() changed to silc_log_set_callback().
2156 ROBOdoc documented silclog header file.
2157 SilcLogCb now returns bool to wether inihibit the default
2158 handler or not (to keep the old behaviour return always TRUE).
2159 The new APIs should also fix the problem of the
2160 silcd_error.log file that was written in the current directory.
2163 Log files streams will remain opened after silc_log_set_file()
2164 call, means less CPU usage notably on high traffic servers.
2165 File streams are now full buffered, and flushed to the disk
2166 every 5 minutes, lesses HD activity and CPU usage.
2167 Messages can be redirected, allowing admins to configure
2168 one single logfile for all server messages.
2169 the silc_log_quick global variable to activate fast-logging.
2170 Affected files lib/silcutil/silclog.[ch]
2172 * Changed some code to conform new silclog APIs. Affected
2173 files are doc/example_silcd.conf.in, silcd/server.c
2174 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
2177 * Fixed a memory leak that could occur in some situations.
2178 Affected file silcd/serverconfig.c.
2180 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2182 * Added the silc_client_del_client to remove the client from
2183 all channels as well. Affected file lib/silcclient/idlist.c.
2185 * Fixed the client library to correctly remove the client
2186 from all channels when the client entry is being destroyed.
2187 Affected file lib/silcclient/client_notify.c, command.c.
2189 * Added auto-nicking support to the client library. If the
2190 applicatio now sets client->nickname it will be sent to the
2191 server after connecting by the library. This way for example
2192 SILCNICK (or IRCNICK) environment variables will have effect
2193 and always change the nickname automatically to whatever
2194 it is wanted. Affected file lib/silcclient/client.[ch].
2196 * Renamed silc_server_command_bad_chars to the
2197 silc_server_name_bad_chars and moved it to the
2198 silcd/server_util.[ch]. Added also new function
2199 silc_server_name_modify_bad to return nickname that
2200 includes bad characters as new nickname without those
2201 bad characters. This check and modify is now used in
2202 silc_server_new_client when the username is initially set
2203 as nickname, so it must be checked to be valid nickname.
2204 Affected file silcd/packet_receive.c.
2206 * The nickname length is now taken from the packet for real
2207 and not trusted to strlen() since it clearly can return
2208 wrong length for nickname including bad characters. This
2209 also applies to channel names. Affected file silcd/command.c.
2211 * Removed the lib/silcsilm/modules directory. Modules are now
2212 compiled into the lib/silcsim. Fixed the copying of the
2213 modules to follow symbolic links in Makefile.am.pre.
2215 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2217 * Fixed silc_string_regexify list creation. Fixes bugs with
2218 BAN and INVITE commands in server. The affected file is
2219 lib/silcutil/unix/silcunixutil.c.
2221 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2223 * Removed the command destructor entirely from the server's
2224 command and command reply routines. It is not needed, and
2225 its usage was buggy and caused crashes. Affected files are
2226 silcd/command[_reply].[ch].
2228 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2230 * Cancel protocol and NULL sock->protocol if timeout
2231 occurred during protocol. Affected file silcd/server.c.
2233 * Cancel protocol timeouts always before calling the final
2234 callback, to assure that after final callback is called
2235 no other state will be called for the protocol anymore.
2236 Affected file silcd/protocol.c.
2238 * Print error log if incoming connection configuration could
2239 not be found. Affected file silcd/server.c.
2241 * Fixed JOIN command to correctly save the founder mode
2242 to the client on normal SILC server, when the channel
2243 was created by the router. Affected file silcd/command.c.
2245 * Fixed LIST command (hopefully) to send correct reply
2246 packets. Affected file silcd/command.c.
2248 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2250 * The silc_packet_receive_process now returns FALSE if the
2251 read data was invalid packet, and TRUE if it was ok.
2253 The server now checks that if unauthenticated connection
2254 sends data and its processing fails the server will close
2255 the connection since it could be a malicious flooder.
2257 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
2259 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2261 * Make sure the warning about error opening a log file is
2262 printed only once and not everytime it fails (produces
2263 too much useless log). Affected file lib/silcutil/silclog.c.
2265 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2267 * Made the silc_server_daemonise() function more readable.
2268 Affected file silcd/server.c.
2270 * Pid file is now optional, the user may comment it out from
2271 the config file. Removed define SILC_SERVER_PID_FILE, we
2272 don't need a default any longer. Affected file
2273 configure.in.pre, lib/Makefile.am.pre.
2275 * Make some use of the pid file. The server now dies at startup
2276 if it detects a valid pid file on his path. The server would
2277 die anyway in this circumstance, because of the bind() failure.
2278 Affected file silcd/silcd.c.
2280 * No longer compiling lib/dotconf.
2282 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2284 * Fixed JOIN command parsing not to crash. Affected file
2285 lib/silcclient/command.c.
2287 * Fied the NICK_CHANGE notify to add the new client entry
2288 even it is resolved. This removes an <[unknown]> nick
2289 thingy bug in the client. Affected file is
2290 lib/silcclient/client_notify.c.
2292 * Do not try to allocate 0 bytes (efence does not like it)
2293 in lib/silccore/silccomand.c when encoding payload.
2295 * Do not take IRCNICK as nickname in Irssi SILC client since
2296 it is not possible to set nickname before hand connecting
2297 the server (TODO has an entry about adding auto-nicking
2300 * Changed the silc_server_command_pending to check whether
2301 there already exists an pending entry with the specified
2302 command, command identifier and pending callback. This is
2303 to fix IDENTIFY and WHOIS related crashes that may register
2304 multiple pending commands with same identifier. Affected
2305 file silcd/command.c.
2307 * Fixed the server to reconnect to the router even if it
2308 was already reconnecting and EOF was received. This to
2309 fix a possibility that the server wouldn't ever try to
2310 auto-reconnect to the router. Affected file silcd/server.c.
2312 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2314 * Fixed the server's password authentication to use the
2315 length of the locally saved password, and not the one
2316 sent in the packet. Affected file silcd/protocol.c.
2318 * Fixed same password authentication problem in the
2319 Authentication Payload handling routines in
2320 lib/silccore/silcauth.c.
2322 * Yet another password authentication problem fixed with
2323 channel password handling in silcd/command.c.
2325 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2327 * If first character of string in silc_parse_userfqdn is '@'
2328 then do not parse it. Affected file is
2329 lib/silcutil/silcutil.c.
2331 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2333 * Fixed minor bug in IDENTIFY command reply sending, which
2334 caused various weird problems during JOIN when it was
2335 resolving names for users. Affected file silcd/command.c.
2337 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2339 * Fixed the IDENTIFY command reply sending to chech better valid
2340 clients. It was possible to send incomplete list of replies.
2341 Affected file silcd/command.c.
2343 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2345 * Added silc_client_command[s]_[un]register functions now to
2346 dynamically register the commands in client library. Removed
2347 the static table of commands. This allows the client library
2348 to call commands without causing the application to know about
2349 what commands library has called.
2351 Removed the INFO command reply kludge to detect when the command
2352 was called by library. Now library use its own command reply
2353 function for INFO command.
2355 Added function silc_client_command_call to call a command.
2356 Application can use it to call command, not access the structure
2359 Now all commands that are sent by the client library (not
2360 explicitly sent by application) use own command reply functions.
2362 Affected files around lib/silcclient/ and in
2363 irssi/src/silc/core/.
2365 * Fixed the WHOIS command reply sending to chech better valid
2366 clients. It was possible to send incomplete list of replies.
2368 Fixed the WHOIS and IDENTIFY to send the request to router
2369 if normal server did not do it and did not find any results.
2371 Affected file silcd/command.c.
2373 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2375 * Moved the internal data from SilcClient context into its
2376 own file, not accesible to application. Affected files
2377 lib/silcclient/client.h and lib/silcclient/client_internal.h,
2378 and other files in client library.
2380 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2382 * Added doc/examples installation target in Makefile.am.pre.
2385 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2387 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
2388 commands the found client entry will be removed from the
2389 cache, after notifying application about the error. Affected
2390 file lib/silcclient/command_reply.c.
2392 * Changed the /MSG to check for exact nickname user gave, and
2393 not let `nick' match `nick@host' if it is only one found. Now,
2394 user must type the exact nickname (like nick@host2) even if
2395 there are no more than one same nicks found. This is to avoid
2396 a possibility of sending nickname to wrong nickname since
2397 `nick' could match `nick@host'. Affected file is
2398 irssi/src/core/silc-servers.c.
2400 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2402 * Do not print "you are now server operator" or similar when
2403 giving /away command. Affected files are
2404 irssi/src/silc/core/client_ops.c, silc-servers.h.
2406 * Made the silc_server_command_pending_error_check to send
2407 the same command reply payload it received back to the
2408 original sender of the command. This way all arguments
2409 that was received by the server will be received by the
2410 client too. Affected file silcd/command.c.
2412 * Added the silc_idcache_add to return the created cache entry
2413 to a pointer. Affected file lib/silccore/silcidcache.[ch].
2415 * Add global clients to expire if they are not on any channel.
2416 This is because normal server will never know if they signoff
2417 if they are not on any channel. The cache expiry will take
2418 case of these entries. This is done by normal servers only.
2419 The affected files are silcd/command_reply.c,
2420 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
2422 * If server receives invalid ID notification for WHOIS or
2423 IDENTIFY and the ID exists in the lists, it is removed.
2424 Affected file silcd/command_reply.c.
2426 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
2427 in client then client entry that it matches is searched and
2428 the nickname is printed on the screen for user. Affected
2429 file irssi/src/silc/core/client_ops.c.
2431 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2433 * Use cache entry expire time in the LIST command reply to
2434 purge old entries from the cache after the LIST command
2435 reply has been received. This way we don't have non-existent
2436 entries in the cache for too long. Affected file is
2437 silcd/command_reply.c.
2439 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2441 * If we are normal server, and we've not resolved client info
2442 in WHOIS or IDENTIFY from router, and it is global client,
2443 we'll check whether it is on some channel. If it is not
2444 then we cannot be sure about its validity and will resolve it
2445 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
2446 file silcd/command.c.
2448 * Search channel by name (if possible) rather than by ID
2449 in IDENTIFY command's command reply. Affected file is
2450 silcd/command_reply.c.
2452 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2454 * Distribute to the channel passphrase in CMODE_CHANGE notify.
2455 Updated specs and implemented it. Affected file silcd/command.c,
2456 silcd/packet_send.c and silcd/packet_receive.c.
2458 * Implemented the <founder auth> payload handling in the JOIN
2459 command. If provided all conditions for channel joining
2460 except requirement to provide correct passphrase can be
2461 overrided by the channel founder. Updated the protocol specs.
2462 Affected file silcd/command.c.
2464 Added support for founder auth in JOIN command in client
2465 library. Fixed the parsing of the JOIN command now to support
2466 all options as they should be. The affected file is
2467 lib/silcclient/command.c.
2469 * Optimized the WHOIS and IDENTIFY commands to send the request
2470 to router only if it includes nicknames or other names. If
2471 they include only IDs then check the local cache first before
2472 routing. Affected file is silcd/command.c.
2474 * Added channels topic announcements. Affected file is
2475 silcd/packet_receive.c and silcd/server.c.
2477 * Fixed the silc_server_send_notify_topic_set to really destine
2478 the packet to channel. Affected file silcd/packet_send.c.
2480 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
2481 library. Affected file lib/silcclient/client_notify.c.
2483 * Added UMODE announcements. Affected file silcd/server.c.
2485 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2487 * Memory leak fixes in:
2489 lib/silcutil/silcsockconn.c
2490 lib/silcske/silcske.c
2491 lib/silcske/groups.c
2493 lib/silccrypt/silcpkcs.c
2494 lib/silccore/silccommand.c
2495 lib/silccore/silcidcache.c
2500 * ROBOdoc documented the lib/silcske/groups.h file and a
2501 bit changed the interface for better.
2503 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2505 * Update the client entry context in the ID cache after
2506 nick change. Affected file lib/silcclient/command.c.
2507 Fixes the CUMODE command when regaining founder privileges,
2508 and a little WHOIS problem.
2510 * Fixed silc_net_gethostbyname to correctly call the
2511 inet_ntop. Affected file lib/silcutil/silcnet.c.
2513 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2515 * Added IPv6 support checking to the configure.in.pre, added
2516 also --enable-ipv6 option to override the check. Affected
2517 file configure.in.pre.
2519 * The silc_thread_create now calls the start function
2520 directly if threads support is not compiled in. Removes
2521 ugly #ifdef's from generic code. Affected files are
2522 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
2524 * Added silc_net_gethostby[name/addr]_async to asynchronously
2525 resolve. Affected files are lib/silcutil/silcnet.[ch].
2527 * Added support for rendering IPv6 based server, client and
2528 channel IDs. Affected file lib/silcutil/silcutil.c.
2530 * Added support for creating IPv6 based server IDs. Affected
2531 file is silcd/serverid.c.
2533 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2535 * Added silc_net_gethostby[addr/name] into the
2536 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
2537 routines. Added silc_net_is_ip[4/6]. Affected file is
2538 lib/silcutil/unix/silcunixnet.c. All routines that take
2539 address as argument now supports both IPv4 and IPv6 addresses.
2541 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2543 * Fixed LIST command reply sending in server. Affected file
2546 * Server now sends the kicker's client ID in the KICK notify
2547 to the kicked client. Affected file silcd/command.c.
2549 * The client library now parses the kickers client ID and
2550 UI displays it. Affected files lib/silcclient/client_notify.c
2551 and irssi/src/silc/core/silc-channels.c, module-formats.c.
2553 * Made all payload parsing function prototypes consistent.
2554 They all take now const unsigned char * and uint32 pair as
2555 the payload data instead of SilcBuffer. Changes all around
2556 the source tree. Other unsigned char* -> const unsigned char*
2557 changes around the tree as well.
2559 * Optimized SFTP client and server packet sending not to
2560 allocate new buffer for each packet but to recycle the
2561 first allocated buffer. Affected files are
2562 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
2564 * Optimized the SFTP client to use SilcList instead of
2565 SilcDList for requests, because it is faster. Affected file
2566 is lib/silcsftp/sftp_client.c.
2568 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
2569 into lib/silccore/silcid.[ch].
2571 Renamed silcpayload.[ch] into silcargument.[ch].
2573 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2575 * If client entry is deleted with active key agreement
2576 session, abort the session.
2578 The silc_client_abort_key_agreement now calls the completion
2579 callback with new SILC_KEY_AGREEMENT_ABORTED status.
2581 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
2584 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2586 * Don't use __restrict in older GCC's. Affected file is
2587 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
2589 * silc_net_localhost now attempts to reverse lookup the
2590 IP/hostname. Affected file lib/silcutil/silcnet.c.
2592 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
2593 command. It can be used to gain founder privileges at
2594 the same time when joining the channel.
2596 Defined that the SILC_NOTIFY_TYPE_KICKED send the
2597 kicker's client ID as well. Updated protocol specs.
2599 Defined that the server must send SILC_COMMAND_IDENTIFY
2600 command reply with error status to client who sent
2601 private message with invalid client ID.
2603 Updated the protocol specification.
2605 * Added silc_server_send_command_reply to send any
2606 command reply. Affected file silcd/packet_send.[ch].
2608 * Added silc_id_payload_encode_data to encode ID payload
2609 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
2611 * The server now send IDENTIFY command reply with error
2612 status if client ID in private message is invalid. Affected
2613 file silcd/packet_receive.c.
2615 * Save the server key file with server's IP address in
2616 the filename instead of hostname. The affected file is
2617 irssi/src/silc/core/client_ops.c.
2619 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2621 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
2624 * Added libtool support for compiling shared objects in
2625 lib/silcsim. Affected file configure.in.pre and
2626 lib/silcsim/Makefile.am. Original patch by cras.
2628 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2630 * Pid file configuration, and server's config file fixes
2631 patch by toma. Updated CREDITS file.
2633 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2635 * Fixed silc_client_channel_message to not try to decrypt
2636 the message twice if it resolved the destination client
2637 information. This could cause of dropping one channel
2638 message. Affected file lib/silcclient/client_channel.c.
2640 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2642 * Added silc_client_run_one into lib/silcclient/silcapi.h and
2643 lib/silcclient/client.c. This function is used when the SILC
2644 Client is run under some other scheduler, or event loop or
2645 main loop. On GUI applications, for example this may be
2646 desired to used to run the client under the GUI application's
2647 main loop. Typically the GUI application would register an
2648 idle task that calls this function multiple times in a second
2649 to quickly process the SILC specific data.
2651 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2653 * Fixed silc_server_drop() for dropping the supplementary
2654 groups as well, this could cause a security hole on some
2657 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2659 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
2662 * Write PID file after dropping privileges. Added -F option
2663 to run server on foreground. A patch by debolaz.
2664 Affected files silcd/server.c, silcd/silcd.c.
2666 * Fixed MOTD to return the MOTD file server name. Affected
2667 file silcd/command.c.
2669 * Added INFO command reply handling to the Irssi SILC Client.
2670 Affected file irssi/src/silc/core/client_ops.c.
2672 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2674 * Fixed the silc_idcache_list_* routines to really support
2675 the dynamic list. Fixes a crash. Affected file is
2676 lib/silccore/silcidcache.c.
2678 * Fixed the LIST command reply to really call LIST command's
2679 pending callbacks. Affected file silcd/command_reply.c.
2681 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2683 * Update conn->local_entry->nickname after giving NICK
2684 command. Affected file lib/silcclient/command.c.
2686 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
2688 * Added the [pid] option to the silcd configuration file
2690 Affected files: serverconfig.[ch] and silcd.c
2692 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2694 * Save fingerprint in WHOIS command reply in server.
2695 Affected file silcd/command_reply.c.
2697 * Fixed NICK commands pending callback registration.
2698 Affected file lib/silcclient/command.c.
2700 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2702 * Use ++server->cmd_ident when sending commands in server,
2703 instead of random number. Affected file silcd/command.c.
2705 * Fixed GETKEY command reply to call actually GETKEY pending
2706 command callbacks. Affected file silcd/command_reply.c.
2708 * A bit stricter check for nicknames. Check for same nickname
2709 in NICK command also. Affected file silcd/command.c.
2711 * Do not call INFO command everytime client ID changes, only
2712 during first connecting. Affected file lib/silcclient/client.c.
2714 * Set the new nickname only after successful command reply for
2715 NICK command is returned by server. Affected file
2716 lib/silcclient/command.c.
2718 * Remove nicknames from nicklist during server_signoff notify.
2719 Should fix /NAMES bit more. The affected file is
2720 irssi/src/silc/core/silc-channels.c.
2722 * Added `fingerprint' field to the SilcIDListData in the
2723 silcd/idlist.h to hold the fingerprint of the client's
2726 Send the fingerprint of the client's public key in WHOIS
2729 Affected files silcd/command.c, and silcd/idlist.[ch].
2731 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
2732 create fingerprint from given data.
2734 * Show the fingerprint of the client's public key in WHOIS.
2735 Affected files irssi/src/module-formats.[ch] and
2736 irssi/src/silc/core/client_ops.c.
2738 * Format the multiple same nicknames also during JOIN and
2739 NICK_CHANGE notifys. Affected file is
2740 lib/silcclient/client_notify.c.
2742 * Do not print error on screen for invalid private message
2743 payload since it can come if someone is sending private
2744 messages with wrong key. Affected file
2745 lib/silccore/silcprivate.c.
2747 * Fixed multiple concurrent /PING crash. Affected file
2748 lib/silcclient/command.c.
2750 * Changed the wrong ID encoding. All IP addresses must be
2751 in MSB first order in encoded format. They were encoded
2752 wrong and was in LSB format. Affected files are
2753 silcd/serverid.c, lib/silcutil/silcutil.c.
2755 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
2757 * Call the `connect' client operation through the scheduler
2758 in case of error. Affected file lib/silcclient/client.c.
2760 * Call the `failure' client operation even if the error
2761 occurred locally during a protocol. Affected file is
2762 lib/silcclient/protocol.c.
2764 * Added support of sending LIST command to router from normal
2765 server. This way normal server can get list of all channels
2766 in the network too. Fixed the channel list sending in the
2767 server too. Affected files are silcd/command.c, and
2768 silcd/command_reply.[ch].
2770 * Added silc_server_update_channels_by_server and
2771 silc_server_remove_channels_by_server. They are used during
2772 disconnection of primary router and in backup router protocol.
2773 Affected file silcd/server_util.[ch], silcd/server.c and
2774 silcd/server_backup.c.
2776 * Fixed channel adding to global list in IDENTIFY command
2777 reply in server. Affected file silcd/command_reply.c.
2779 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2781 * If the incoming packet type is REKEY or REKEY_DONE process
2782 that packet always synchronously. Fixes yet another MAC
2783 failed error on slow (dialup) connections. Affected file
2784 lib/silcclient/client.c and silcd/server.c.
2786 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2788 * Call check_version SKE callback for initiator too. Affected
2789 file lib/silcske/silcske.c.
2791 * Implemented fix for security hole found in the SKE that was
2792 fixed in the specification few days back; the initiator's
2793 public key is now added to the HASH value computation.
2794 Added backwards support for the old way of doing it too, for
2795 old clients and old servers. Affected file is
2796 lib/silcske/silcske.c.
2798 * Enabled mutual authentication by default in SKE. If initiator
2799 is not providing mutual authentication the responder will
2800 force it. This will provide the proof of posession of the
2801 private key for responder. The affected files are
2802 lib/silcclient/protocol.c and silcd/protocol.c.
2804 * Do not cache anymore the server's public key during SKE.
2805 We do mutual authentication so the proof of posession of
2806 private key is done, and if the server is authenticated in
2807 conn auth protocol with public key we must have the public
2808 key already. Affected file silcd/protocol.c.
2810 * Added new global debug variable: silc_debug_hexdump. If
2811 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
2812 file lib/silcutil/silclog.[ch].
2814 * Fixed compilation warning due to char * -> const char *.
2815 Affected files lib/silcutil/silcnet.h, and
2816 lib/silccore/silcauth.[ch].
2818 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2820 * Fixed CMODE command when new channel key was created. If
2821 the creation failed the old key was removed. Next time giving
2822 same command would crash the server since the old key was
2823 freed already. Affected file silcd/command.c.
2825 * Fixed the silc_server_announce_get_channels to not crash
2826 on reconnect. Affected file silcd/server.c.
2828 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2830 * Added silc_log_set_debug_string function to set a regex
2831 string to match for debug output. Only the function names,
2832 or filenames matching the given debug string is actually
2833 printed. This way it is possible to filter out those debug
2834 strings that user is not interested in.
2836 Fixed a bug in silc_string_regexify.
2838 Affected files lib/silcutil/silclog.[ch], and
2839 lib/silcutil/unix/silcunixutil.c.
2841 * Changed the -d options in both server and Irssi SILC client
2842 to take the debug string as argument. Affected files
2843 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
2845 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2847 * Added silc_hash_babbleprint to create a Bubble Babble
2848 Encoded fingerprint. The encoding is developed by Antti
2849 Huima (draft-huima-babble-01.txt), and it creates human
2850 readable strings out of binary data. Affected file
2851 lib/silccrypt/silchash.[ch].
2853 * Print the babble print now in addition of fingerprint as well
2854 in Irssi SILC client. Affected files are
2855 irssi/src/fe-common/silc/module-formats.[ch],
2856 irssi/src/fe-common/silc/core/client_ops.c.
2858 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2860 * Fixed a security problem found in SKE. The initiator's
2861 public key too is now added to the HASH hash value creation
2862 which is signed by the responder to create the SIGN value.
2863 This will prevent anyone in the middle to lie to the responder
2864 about the initiator's public key. If this is done now, the
2865 man in the middle will get caught. Updated the protocol
2868 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2870 * Better installation directory handling. Configure module
2871 paths and other paths automatically to example_silc* files
2872 in doc/. A patch by toma.
2874 * Fixed compiler warning from MPI library, and from SILC RNG.
2877 * Added SILC_SERVER_PID_FILE to define the pid file for server.
2878 It can be configured with ./configure. A patch by toma.
2880 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2882 * Find correct make to use in prepare-clean. A patch by
2883 toma. Affected file prepare-clean.
2885 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
2887 * Added irssi variables use_auto_addr, auto_bind_ip,
2888 auto_bind_port and auto_public_ip.
2890 * Changed the interface for silc_client_send_key_agreement
2891 in lib/silcclient/silcapi.h
2895 irssi/src/silc/core/silc-core.c
2897 lib/silcclient/silcapi.h
2898 irssi/src/silc/core/silc-channels.c
2899 lib/silcclient/client_keyagr.c
2902 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2904 * Added silc_pkcs_public_key_compare to compare two
2905 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
2907 * Check that the client who set the founder mode on the
2908 channel is the same client that is giving the founder
2909 mode to itself. It is done by comparing the saved public
2910 key (it is saved even in the authentication is passphrase).
2911 Affected file silcd/command.c.
2913 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2915 * Do not process packet for disconnected socket connection.
2916 Affected file lib/silccore/silcpacket.c.
2918 * Process the DISCONNECT packet through scheduler in the
2919 client library. Affected file lib/silcclient/client.c.
2921 * Fixed the silc_client_packet_parse to not to increase
2922 the packet sequence number if the conn->sock and the
2923 current socket connection is not same. This can happen
2924 for example during key agreement when the conn includes
2925 multiple socket connections (listeners). Affected file
2926 lib/silcclient/client.c.
2928 * The sender of the file transfer request now provides also
2929 the pointer (listener) for the key exchange protocol. If
2930 the listener cannot be created then it sends empty key
2931 agreement and lets the receiver provide the listener.
2933 Added `local_ip' and `local_port' arguments to the
2934 silc_client_file_send. If they are provided they are used,
2935 if not then it will attempt to find local IP address, if
2936 not found or bind fails then the remote client will provide
2939 Affected files are lib/silcclient/client_ftp.c and
2940 lib/silcclient/silcapi.h.
2942 * Extended the FILE SEND command to support defining the
2943 local IP and port for key exchange listener. They are
2944 optional. Affected file irssi/src/silc/core/silc-servers.c.
2946 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2948 * Defined to WHOIS command reply the sending of fingerprint
2949 of the client's public key (if the proof of posession of the
2950 corresponding private key is verified by the server).
2951 Updated to the protocol specification.
2953 * Added support of receiving the client's public key's
2954 fingerprint in command reply in client library. Affected
2955 file is lib/silcclient/command_reply.c, and
2956 lib/silcclient/idlist.[ch].
2958 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2960 * Do not send over 128 chars long nickname to the server
2961 in NICK command. Affected file lib/silcclient/command.c.
2963 * Do not send over 256 chars long channel names to the server
2964 in JOIN command. Affected file lib/silcclient/command.c.
2966 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2968 * Assure that silc_server_close_connection cannot be called
2969 twice for same socket context. Affected file is
2972 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2974 * Send error message to application if opening file for
2975 writing during file transfer fails. Affected file is
2976 lib/silcclient/client_ftp.c.
2978 Remove all file transfer sessions for a client that we're
2979 removing from ID cache.
2981 Affected file is lib/silcclient/client_ftp.c.
2983 * Fixed silc_net_addr2bin to return correct address. Affected
2984 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2986 * Fixed file transfer session removing on signoff notify.
2987 Affected file irssi/src/silc/core/silc-servers.c.
2989 * Added the SilcClientFileError to be returned in the monitor
2990 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
2991 Affected file lib/silcclient/silcapi.h.
2993 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2995 * Fixed a crash in silc_client_ftp_free_sessions and
2996 silc_client_ftp_session_free_client. Affected file
2997 lib/silcclient/client_ftp.c.
2999 * Added `disabled' field in the SilcChannelEntry in the server
3000 to indicate if the server entry is disabled. Affected file
3001 silcd/idlist.h, silcd/command[_reply].c.
3003 * SILC server adds now /var/run/silcd.pid everytime it is
3004 started. Affected file silcd/silcd.c.
3006 * Added silc_server_packet_send_clients to send a packet to
3007 the provided table of client entries. Affected file
3008 silcd/packet_send.[ch].
3010 * Fixed a crash in client resolving in client_prvmsg.c in
3011 client library. Affected file lib/silcclient/client_prvmsg.c.
3013 * Do not actually remove the client directly from ID cache
3014 during SERVER_SIGNOFF, but invalidate it. This way we
3015 preserve the WHOWAS info for the client. Affected file
3016 silcd/server_util.c.
3018 * Fixed SERVER_SIGNOFF notify handling in the server. The
3019 server is now able to process incoming SERVER_SIGNOFF notify
3020 for a server that it doesn't even know about. It will remove
3021 the clients provided in the notify. Affected file
3022 silcd/packet_receive.c.
3024 * Check for partial packet in data queue after every packet that
3025 was found from the queue. Return and wait for more data if
3026 there is partial data in queue. Affected file is
3027 lib/silccore/silcpacket.c.
3029 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3031 * Added SilcClietFileError enum to indicate error in
3032 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
3033 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
3034 Affected files lib/silcclient/silcapi.h and
3035 lib/silcclient/client_ftp.c.
3037 * Check that newsize in silc_buffer_realloc is larger than
3038 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
3040 * Added better monitor of file transfers. It now monitors
3041 key agreement protocol during the file transfer too. Added
3042 error reporting too. Affected files
3043 irssi/src/silc/core/silc-servers.c,
3044 irssi/src/fe-common/silc/module-formats.[ch].
3046 * Wrote a help file for FILE command.
3048 * Added silc_rng_global_get_byte_fast to get not-so-secure
3049 random data as fast as possible. Random data is read from
3050 /dev/urandom if available and from the SILC RNG if not
3051 available. It is used in padding generation. Affected file
3052 lib/silccrypt/silcrng.[ch].
3054 * All packets in client library are now processed synchronously.
3055 Optimized packet processing a lot. Affected file
3056 lib/silcclient/client.c.
3058 * All server connection packets are processing synchronously
3059 now in server, to optimize packet processing. Affected file
3062 * Include files are installed now only in Toolkit distribution
3063 if make install is given. Affected files: all Makefile.am's.
3065 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3067 * Assure that silc_client_notify_by_server_resolve does not
3068 resolve the client information multiple times. If it cannot
3069 be found by the first it cannot be found at all. Affected
3070 file lib/silcclient/client_notify.c.
3072 * Fixed WHOWAS command reply calling. Affected file
3073 lib/silcclient/command_reply.c.
3075 * Removed all references to silc_idlist_get_client from the
3076 Irssi SILC client since that call is internal call used by
3077 the library. The Irssi SILC client will use now client
3078 retrieval functions found in silcapi.h.
3080 * Fixed a bug in resolving nickname info before sending
3081 private message. It used freed memory. Affected file
3082 irssi/src/silc/core/silc-servers.c.
3084 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3086 * Assure my_channels statistics cannot go negative in server.
3087 Affected files silcd/server.c, silcd/server_util.c.
3089 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3091 * Upgraded dotconf 1.0.2 to 1.0.6 in lib/dotconf.
3093 Tue Oct 23 13:51:19 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3095 * Win32 Toolkit changes. Affected files
3096 win32/silc.dsw, win32/libsilc/libsilc.def,
3097 win32/libsilcclient/libsilc.def,
3098 lib/silcutil/silcutil.c, and
3099 lib/sftp/sftp_fs_memory.c.
3101 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3103 * Added silc_net_localip to return local host's IP address.
3104 Affected file lib/silcutil/silcnet.[ch].
3106 * If key exchange or rekey protocol is active for a connection
3107 parse all packets syncronously since there might be packets
3108 in packet queue that we are not able to process without first
3109 processing packets before them. Affected file silcd/server,
3110 lib/silcclient/client.c.
3112 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
3113 whether library should continue processing the packet.
3114 Affected file lib/silccore/silcpacket.h.
3116 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
3117 SilcSFTPMonitorData to SFTP server to monitor various
3118 SFTP client requests. Affected file lib/silcsftp/silcsftp.h,
3119 lib/silcsftp/sftp_server.c.
3121 * Added silc_file_size to return file size. Affected file
3122 lib/silcutil/silcutil.[ch].
3124 * Implemented the file transfer support for the client library.
3125 Added preliminary support for simple client to client one-file
3126 transmission. Affected file lib/silcclient/client_ftp.c,
3127 lib/silccilent/client.[ch].
3129 * Added new local command FILE to the Irssi SILC Client.
3130 It is used to perform the file transfer. It has subcommands
3131 SEND, RECEIVE, SHOW and CLOSE. Affected files
3132 irssi/src/silc/core/client_ops.c,
3133 irssi/src/silc/core/silc-server.[ch].
3135 Mon Oct 22 12:50:08 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3137 * Relay the SILC_PACKET_FTP in the server. Affected files
3138 silcd/server.c and silcd/packet_receive.c.

3142 * Renamed silc_file_read and silc_file_write to functions
3143 silc_file_readfile and silc_file_writefile. Added function
3144 silc_file_open and silc_file_close. Affected files
3145 lib/silcutil/silcutil.[ch].
3147 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3149 * Resolve the client info when received private message or
3150 channel message for a client which nickname we don't know.
3151 Affected files lib/silcclient/client_prvmsg.c and
3152 lib/silcclient/client_channel.c.
3154 * Do not crash in /KEY if client is not connected. Affected
3155 file irssi/src/silc/core/silc-channels.c.
3157 * Added SilcClientStatus field to the SilcClientEntry in the
3158 lib/silcclient/idlist.h.
3160 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
3161 is incomplete and is being resolved, it won't be resolved
3164 Make sure also that USERS command reply does not resolve
3165 twice information. Affected file is
3166 lib/silcclient/command_reply.c.
3168 Make sure that silc_client_get_clients_by_list does not
3169 resolve twice same information.
3171 * Check for valid client->id in the silc_server_free_client_data.
3172 Affected file silcd/server.c.
3174 * Fixed /GETKEY nick@server not to crash if the server entry
3175 is not found. Affected file lib/silcclient/command.c.
3177 * Fixed the silc_server_check_cmode_rights to check the
3178 requested modes correctly. Affected file silcd/command.c.
3180 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3182 * Better checks for non-printable chars in nick added.
3183 Affected file silcd/command.c.
3185 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3187 * Call the silc_server_udpate_servers_by_server in the
3188 primary router that comes back online in the backup resuming
3189 protocol. Otherwise it routes packets wrong. Affected file
3190 silcd/server_util.[ch], silcd/server_backup.c.
3192 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3194 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
3195 lib/silcutil/silcbuffmt.[ch].
3197 * Redefined the SILC packet header to include the padding
3198 length. Affected file lib/silccore/silcpacket.[ch].
3200 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
3201 length for maximum padding up to 128 bytes). Affected
3202 file lib/silccore/silcpacket.h.
3204 * Removed all backwards support for old 0.5.x MAC thingies.
3205 The SILC packet header change makes it impossible to be
3206 backwards compatible.
3208 * Send the ENDING packet with timeout in the backup resuming
3209 protocol. This is to assure that all routers has connected
3210 to the primary router. Affected file silcd/server_backup.c.
3212 * Changed the RNG to take the first IV from random data. It
3213 used to take it from zero actually. Changed the RNG also
3214 to use /dev/urandom during session. /dev/random is used
3215 in initialization. Affected file lib/silccrypt/silcrng.[ch].
3217 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3219 * Changed the SILC packet header to have the first two bytes
3220 (the packet length) encrypted. Affected files aroung the
3221 code tree, lib/silccore/silcpacket.[ch]. Removed the
3222 SilcPacketCheckDecrypt callback. It is not needed anymore
3223 since the silc_packet_receive_process will determine now
3224 whether the packet is normal or special.
3226 * Implemented the unidirectional MAC keys. Affected files
3227 lib/silcske/silcske.c, silcd/protocol.c and
3228 lib/silcclient/protocol.c.
3230 * Implemented the packet sequence number to the MAC computation.
3231 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
3232 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
3233 lib/silcclient/protocol.c.
3235 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3237 * Allow backup router to announce servers. All servers
3238 announced by backup router are added to the global list
3239 automatically. Update hte server's socket to our primary
3240 router also when backup router announces a server.
3241 Affected file silcd/packet_receive.c.
3243 * Do not update the client->router in the function
3244 silc_server_udpate_clients_by_server if the client is on
3245 global list. We might fail to find any specific server
3246 for locally connected clients and local cell clients. They
3247 should still use the `from' and not `to' as client->router.
3248 This fixes backup router resuming protocol. Affected file
3249 silcd/server_util.c.
3251 * Decrease channel statistics count only if the channel
3252 deletion worked. Affected files are silcd/server.c and
3253 silcd/server_util.c.
3255 * Added silc_server_update_servers_by_server to update origin
3256 of all server entries. Used during backup router protocol.
3257 Affected files silcd/server_util.[ch], silcd/server.c. and
3258 silcd/backup_router.c.
3260 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
3261 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
3262 silc_hmac_get_hash and silc_hmac_get_name. Affected file
3263 lib/silccrypt/silchmac.c.
3265 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3267 * Assure that router cannot reroute the same channel message
3268 to the sender. Affected file silcd/packet_receive.c.
3270 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3272 * Made better checks that the channel message is not sent
3273 to the router it came from. Affected file is
3274 silcd/packet_send.c. Fixed memory leak too.
3276 * Announce informations for incoming router connection, but
3277 only after checking if it is replaced by backup router.
3278 Affected file silcd/packet_receive.c.
3280 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3282 * Fixed the backup resuming protocol to work in multiple
3283 router environment. Affected file silcd/server_backup.c.
3285 * Route packet only to one router in the function
3286 silc_server_packet_send_to_channel. Affected file is
3287 silcd/packet_send.c.
3289 * Fixed silc_server_send_notify_dest to set the broadcast
3290 flag. Fixed the silc_server_send_notify_topic to actually
3291 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
3292 Affected file silcd/packet_send.c.
3294 * Changed the SFTP Filesystem interface. Changed the
3295 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
3296 the filesystem operation function. The SilcSFTPFilesystem
3297 is now a context that is allocated by all filesystem allocation
3298 functions and it already includes the operations structure
3299 and filesystem specific context. It is given as argument
3300 now to the silc_sftp_server_start. This made the interface
3301 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
3302 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
3304 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3306 * Changed the backup router adding and getting interfaces
3307 in the server. The router that will be replaced by the
3308 specified backup router is now sent as argument. Affected
3309 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
3312 * Added silc_net_addr2bin_ne to return the binary form of
3313 the IP address in network byte order. Affected files
3314 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
3316 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3318 * Check for existing server ID in silc_server_new_server
3319 and in silc_server_connect_to_router_final and remove the
3320 old entry if it exists. Affected file silcd/packet_receive.c,
3323 * Send the channel message always to only one router, either
3324 in upstream or downstream. Affected file is
3325 silcd/packet_send.c.
3327 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3329 * Wrote the definition of the backup resuming protocol to the
3330 protocol specification.
3332 * Removed one redundant channel key generation from normal
3333 server during joining procedure. Removed one redundant
3334 channel key sending from server to router during joining
3335 procedure. Affected file silcd/command.c.
3337 * Made minor bugfixes to the backup router resuming protocol.
3338 Affected file silcd/server_backup.c, server.c.
3340 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3342 * Added --disable-asm configuration option. Affected files
3343 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
3346 * Implemented the backup resuming protocol that is used to
3347 resume the primary router position in the cell after the
3348 primary router comes back online. Affected files
3349 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
3350 and silcd/server_util.[ch].
3352 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3354 * Sleep two (2) seconds after sending QUIT command to server.
3355 Affected file lib/silcclient/command.c.
3357 * Assure that if outgoing data buffer is pending do not force
3358 send any data. Affected file silcd/packet_send.c.
3360 * Assure that if outgoing data buffer is pending do not force
3361 send any data. Affected file lib/silcclient/client.c.
3363 * Implemented the backup router support when the primary router
3364 goes down. The servers and routers can now use the backup
3365 router as new primary router without loosing connectivity.
3367 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3369 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
3370 in the server to indicate disabled entry. All data read
3371 from the connection will be ignored and no data is sent
3372 for entry that is disabled. Affected files are
3373 silcd/idlist.h, silcd/server.c.
3375 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3377 * Created SFTP client and server test programs in the
3378 lib/silcsftp/tests directory.
3380 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3382 * Implemented memory filesystem (virtual filesystem) for
3383 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
3386 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3388 * Implemented the SFTP (SSH File Transfer Protocol) to the
3389 lib/silcsftp. It includes SFTP client and SFTP server
3392 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3394 * Moved lib/silccore/silcprotocol.[ch] to the
3395 lib/silcutil library.
3397 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
3398 take variable argument list pointer as argument. Affected
3399 file lib/silcutil/silcbuffmt.[ch].
3401 * Added silc_buffer_set function that is used to set data
3402 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
3403 Affected file lib/silcutil/silcbuffer.h.
3405 * Changed various routines in the core library to use the new
3406 silc_buffer_set instead of allocating new buffer only for
3409 * Added 64-bit value formatting and unformatting support to the
3410 silc_buffer_[un]format routines. Affected file is
3411 lib/silcutil/silcbuffmt.[ch].
3413 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
3414 to includes/bitmove.h.
3416 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3418 * Fixed channel user mode saving in client library. Affected
3419 file lib/silcclient/command[_reply].c.
3421 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3423 * Defined the file transfer to the SILC Protocol. Added
3424 new packet type SILC_PACKET_FTP and defined File Transfer
3425 Payload. The mandatory file transfer protocol is SFTP
3426 (SSH File Transfer Protocol). Affected file in addition
3427 of the internet draft is lib/silccore/silcpacket.h.
3429 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
3430 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
3431 is used as part of backup router protocol when the primary
3432 router of the cell is back online and wishes to resume
3433 the position as primary router.
3435 * Redefined the MAC generation keys in the protocol. The
3436 same key is not used anymore in both direction. Both
3437 direction will now use different keys for sending and
3438 receiving. This fixes a potential security flaw. This
3439 change causes incompatibilities in the protocol.
3441 * Redefined also the MAC computation from the packet.
3442 An packet sequence number is now added to the MAC
3443 computation. This prevents possible replay attacks against
3444 the protocol. This change too causes incompatibilities
3447 Added `sequence' field to the SilcPacketContext to hold
3448 the current sequence number for the packet.
3450 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3452 * Added `created' field to the SilcIDListData in the file
3453 silcd/idlist.h to indicate the time when the entry was
3456 * Added `created' field to the SilcChannelEntry too. Affected
3457 file silcd/idlist.h.
3459 * Added `creation_time' aguments to all the announcement functions
3460 in the server. If it is provided then only the entries that
3461 was created after the provided time frame are actually
3462 announced. Affected file silcd/server.[ch].
3464 * The protocol says that the Channel ID's IP address must be
3465 based on the router's IP address. Added check for this in
3466 the silc_server_new_channel when processing incoming New Channel
3467 Payload. Affected file silcd/packet_receive.c.
3469 * Print out the correct version with --version in SILC client.
3470 Affected file irssi/src/silc/core/silc-core.c.
3472 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3474 * Fixed WHOWAS command to check for completnes of the client
3475 entry always, not just when the command is coming from client.
3476 Affected file silcd/command.c.
3478 * Added new function silc_server_packet_queue_purge to purge the
3479 outgoing data queue to the network. After the function returns
3480 it is guaranteed that the outgoing packet queue is empty.
3481 Affected file silcd/packet_send.[ch].
3483 * Purge the outgoing packet queue in the rekey protocol's final
3484 callback to assure that all rekey packets go to the network
3485 before quitting the protocol. Affected file silcd/server.c.
3487 * Added silc_client_packet_queue_parse as similar function as
3488 in server to the client library. The affected file is
3489 lib/silcclient/client.c.
3491 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3493 * Splitted silcd/server.c and created silcd/server_util.[ch]
3494 for utility functions.
3496 * Added new socket flag SILC_SF_DISABLED to indicate that the
3497 connection is open but nothing can be sent to or received from
3498 the connection. Affected file lib/silcutil/silsockconn.[ch].
3499 The checking for disabled socket is checked in the low level
3500 silc_socket_write and silc_socket_read functions.
3502 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3504 * Allow only nicknames and channel names that fits into the
3505 7-bit unsigned char ASCII set. Affected file silcd/command.c.
3507 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3509 * When processing JOIN command reply in server check that if
3510 the channel exists in our global list we'll move it the local
3511 list. Affected file silcd/command_reply.c.
3513 * Fixed the check whether client is joined on the channel already
3514 in JOIN command. Affected file lib/silcclient/command.c.
3516 * Fixed the JOIN command reply to check whether the channel
3517 already exists. Affected file lib/silcclient/command_reply.c.
3519 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3521 * Added silc_ske_status_string to map the SKE error numbers
3522 to readable strings. The affected files are
3523 lib/silcske/silcske[_status].[ch].
3525 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3527 * Do not show the private channels on the WHOIS channel list
3528 as it is not allowed by the protocol. The affected file is
3531 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3533 * Assure that the packet length digged from the actual packet
3534 is something sensible in the silc_packet_decrypt_rest_special
3535 in lib/silccrypt/silcpacket.c.
3537 * Free and NULL the allocated pointer in silc_hmac_alloc if
3538 the HMAC allocation fails. The affected file is
3539 lib/silccrypt/silchmac.c.
3541 * Print the selected security properties to the log files in
3542 the server. Affected file silcd/protocol.c.
3544 * Add SKE's reference counter even if calling the completion
3545 callback manually. Otherwise it goes negative, although it
3546 does not cause any problems. The affected file is
3547 lib/silcske/silcske.c.
3549 * Remove the client entry with short timeout after giving the
3550 KILL command. Affected file lib/silcclient/command.c.
3552 * Fixed to send error reply in WHOIS and IDENTIFY commands in
3553 case all found clients are already disconnected (WHOWAS would
3554 found them) in the server. Affected file silcd/command.c.
3556 * Update the last_receive (time of last data received) to be
3557 updated only when received private or channel message so that
3558 the idle time showed in WHOIS makes more sense.
3560 * Added boolean field `valid' in to the SilcClientEntry in the
3561 client library to indicate whether the entry is valid or not.
3562 This fixes the nickname change bug on channel when changing
3563 the nickname to be same than the old (like nick to Nick) the
3564 nickname formatter doesn't set the new nick anymore to Nick@host.
3565 Affected file lib/silcclient/idlist.[ch].
3567 * Now actually fixed the nickname changing on disconnection.
3568 Added new function silc_change_nick to the Irssi SILC Client.
3569 Affected file irssi/src/silc/core/client_ops.c,
3570 irssi/src/silc/core/silc-nicklist.[ch].
3572 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3574 * Check that the public key exists in the GETKEY command before
3575 trying to encode it. Affected file silcd/command.c.
3577 * Print some notifications on received public keys with GETKEY
3578 command in the Irssi SILC Client. Affected files are
3579 irssi/src/fe-common/silc/module-formats.[ch],
3580 irssi/src/silc/core/client_ops.c.
3582 * Use IDENTIFY command to resolve the server information in the
3583 GETKEY command instead of INFO command. Affected file
3584 lib/silcclient/command.c.
3586 * All command reply functions in the client library now calls
3587 the pending command reply callbacks even if an error has
3588 occurred. The server has done this a long time and now it was
3589 time to move the client library to this as well. Now all
3590 errors can be delivered back to the pending command reply
3591 callbacks if necessary. Affected files are
3592 lib/silcclient/command[_reply].[ch].
3594 * Change the nickname on disconnection back to the username
3595 because in reconnect the server will enforce it to it anyway.
3596 Affected file irssi/src/silc/core/silc-servers.c.
3598 * Fixed a config file parsing bug in the Irssi SILC client.
3599 Affected file irssi/src/silc/core/clientconfig.c.
3601 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3603 * When printing the channel mode on JOIN, verify that the
3604 channel key and channel's HMAC are valid. Affected file
3605 irssi/src/silc/core/client_ops.c.
3607 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3609 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
3610 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
3611 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
3613 * Removed channel key rekey task deleting from the function
3614 silc_server_save_channel_key. Affected file silcd/server.c.
3615 Added explicit timeout task context instead that is used to
3616 delete the task if we are registering a new task before the
3617 new task has elapsed.
3619 * When channel key rekey occurs the client library now saves
3620 the old channel key for a short period of time (10 seconds) and
3621 is able to use it in case some is still sending channel
3622 messages encrypted with the old key after the rekey. Affected
3623 file lib/silcclient/[idlist.h|client_channel.c].
3625 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3627 * Added check to the silc_server_new_id_real to not accept
3628 new ID if it is the sender's own ID. Affected file is
3629 silcd/packet_receive.c.
3631 * Assure that we do not announce ourself or the one we've
3632 sending our announcements when we're router and are announcing
3633 servers to our primary router. Affected file silcd/server.c.
3635 * Fixed silc_server_command_identify_check_client to assemble
3636 correct WHOIS packet. It send corrupted WHOIS packet and
3637 caused problem with router to router connections. Affected
3638 file silcd/command.c.
3640 Fixed also silc_server_command_whois_check the same way
3641 as for the IDENTIFY command.
3643 * Added new SilcIDListStatus to the server in the SilcIDListData
3644 structure. The status now includes the current status of
3645 the entry (like registered, resolved etc.). Affected file
3646 silcd/idlist.[ch]. Defined a bunch of different status types
3647 as well. This replaced the old boolean registered field as well.
3649 Added resolve_cmd_ident field to the SilcClientEntry structure
3650 too so that if the entry is for example being resolved so
3651 another command may attach to the same pending command reply
3652 without requiring to resolve the same entry again. This concept
3653 should optimize the WHOIS and the IDENTIFY resolving under
3654 heavy load by taking away unnecessary resolving for entries
3655 that are being resolved already.
3657 Added support for adding multiple pending commands for one
3658 command idenfier. Affected file silcd/command[_reply].[ch].
3660 * Fixed WHOIS and IDENTIFY save to remove the cache entry
3661 before deleting the data. Otherwise the hash table will have
3662 freed data in comparison functions. Affected file is
3663 silcd/command_reply.c.
3665 * Fixed silc_idlist_replace_client_id to add the new entry to
3666 the cache with NULL nickname. Otherwise there will be invalid
3667 memory as the nickname after the nickname is freed. Affected
3668 file silcd/packet_receive.c.
3670 * Fixed the silc_idlist_get_clients_by_hash. The entries was
3671 saved into wrong slots because the previous number of entries
3672 was not taken into account. Affected file silcd/idlist.c.
3673 Fixed same thing in silc_idlist_get_clients_by_nickname too.
3675 * If we are router and we receive JOIN notify to a channel that
3676 does not have any users then notified client is marked as the
3677 channel founder, as it is it. The affected file is
3678 silcd/packet_receive.c
3680 * Added to the extended hash table API's table_del_*ext functions
3681 the destructor as argument too, so that the caller can decide
3682 which destructor to use or whether to use destructor at all.
3683 Affected file lib/silcutil/silchashtable.[ch].
3685 * Fixed ID Cache purging. It actually deleted the entries from
3686 the hash table after the data was freed. The hash table ended
3687 up comparing freed memory. The affected file is
3688 lib/silccore/silcidcache.c.
3690 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3692 * Fixed Irssi SILC client's KILL command's HELP syntax.
3694 * The USERS command now resolves the detailed user information
3695 if the userinfo field is missing. Affected file is
3696 lib/silcclient/command_reply.c.
3698 * Do not print error in silc_file_read if the read file does
3699 not exist. Just silently return NULL. Affected file is
3700 lib/silcutil/silcutil.c.
3702 * Fixed the silc_log_output to not wine about NULL filename
3703 and to not create some bogus " " filename. Affected file is
3704 lib/silcutil/silclog.c.
3706 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3708 * Fixed various printing bugs on the user interface in the
3709 Irssi SILC Client. Minor changes that were forgotten from
3712 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3714 * Fixed the configure.in.pre and the compilation and distribution
3715 environment to support the new autoconf 2.52. That version is
3716 now required to compile the CVS trunk.
3718 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3720 * Renamed function silc_parse_nickname to silc_parse_userfqdn
3721 to generally parse user@fqdn format strings. Affected file
3722 lib/silcutil/silcutil.c.
3724 * Added nickname_format and nickname_force_format fields to the
3725 SilcClientParams structure. The first one defines the format
3726 for the nicknames that the library will enforce if the receives
3727 multiple same nicknames. The second one is boolean value and
3728 can be used to force the library to always enforce the format
3729 to the nicknames regardles whether there are multiple nicknames
3730 or not. This configurable formatting was employed to flexibly
3731 support accessing multiple nicknames from the user interface.
3732 The userinterface can now set the nicknames to what ever format
3733 they prefer. Affected file lib/silcclient/silcapi.h.
3735 Added function silc_client_nickname_format to the file
3736 lib/silcclient/idlist.c. It performs the nickname formatting.
3738 Added new field `hostname´ to the SilcClientEntry context.
3739 It holds the hostname of the client. Affected file is
3740 lib/silcclient/idlist.h.
3742 * Irssi SILC Client sets the nicknames in nick@hostn format.
3743 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
3744 irssi/src/silc/core/silc-core.c.
3746 The WHOIS printing now also shows both the real nickname and
3747 the formatted nickname so that user knows how to access the
3748 user if there are multiple same nicknames cached. Affected
3749 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
3750 printing formatting too to take the hostname now as a separate
3751 argument. The Affected file is
3752 irssi/src/fe-common/silc/modules-formats.[ch].
3754 * Changed the silc_client_get_clients_local to accept the formatted
3755 nickname as argument. It accepts the real nickname too but the
3756 formatted nickname can be used to find the true entry from
3757 multiple entries. Affected file lib/silcclient/silcapi.h and
3758 lib/silcclient/idlist.c.
3760 * Added nickname_format_parse field to the SilcClientParams.
3761 It is a callback function provided by the application to parse
3762 the nickname out of the formatted nickname string. The library
3763 calls it to get the nickname from the formatted string. Since
3764 the application generally knows better the format of the nickname
3765 string it parses it instead of the library, even though library
3766 encodes the formatted string. If the callback function is not
3767 provided then the library will use the string as is. The
3768 affected file is lib/silcclient/silcapi.h.
3770 * All the nickname strings passed to the client library in
3771 commands are now expected to be formatted nickname strings.
3772 If the command does not support the formatted nickname string
3773 it will assume that the sent string is the actual nickname.
3774 Affected file lib/silcclient/command.c.
3776 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3778 * Added public key authentication support to OPER and SILCOPER
3779 commands in the client library. Affected file is
3780 lib/silcclient/command.c.
3782 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3784 * Changed the get_auth_methdod client operation to be asynchronous.
3785 It can be async if the application resolves the authentication
3786 method from the server during the negotiation. Added new
3787 SilcGetAuthMeth completion callback that the application will
3788 call after resolving the authentication method.
3790 Added function silc_client_request_authentication_method that
3791 the application can use to resolve the authentication method
3792 from the server. Added also SilcConnectionAuthRequest callback
3793 that the library will call after the server has replied. The
3794 application can call this function if it does not know the
3795 current authentication method.
3797 Affected files are lib/silcclient/client.c and
3798 lib/silcclient/silcapi.h.
3800 * The Irssi SILC client now automatically resolves the authentication
3801 method incase any configuration information is not present (and
3802 currently there never is). The affected file is
3803 irssi/src/silc/core/client_ops.c.
3805 * Fixed public key authentication from the client library.
3806 Affected file lib/silcclient/protocol.c. Changed also the
3807 protocol specification about the public key authentication in
3808 the connection authentication protocol. The actual data to be
3809 signed is now computed with a hash function before signing.
3811 * Fixed the public key authentication from the server as well.
3812 Affected file silcd/protocol.c.
3814 * Removed the mlock()'s from the memory allocation routines.
3815 Affected file lib/silcutil/silcmemory.c. The ./configure does
3816 not check anymore for the mlock(). Affected file is
3819 * Fixed USERS command in server to allow the execution of the
3820 command for private and secret channels if the client sending
3821 the command is on the channel. Affected file silcd/command.c.
3823 * Fixed silc_client_get_clients_local to return the clients
3824 count correctly. It could return wrong value. Affected file
3825 lib/silcclient/idlist.c.
3827 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3829 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
3830 types. The assembler optimizations seemed not to like 64-bit
3831 data types. The assmebler optimizations thus are now enabled
3832 also for BSD systems as opposed to only enable them for Linux.
3834 * Do not check for threads at all on BSD systems. Affected
3835 file configure.in.pre.
3837 * Removed -n and -h options from the Irssi SILC Client since
3838 they are not used in silc.
3840 * Fixed the prime generation to assure that the first digit
3841 of the generated random number is not zero since our conversion
3842 routines does not like number strings that starts with zero
3843 digit. If zero digit is seen the random number is regenerated.
3844 This caused some corrupted RSA keys when the zero first digit
3845 was met. Affected file lib/silcmath/silcprimegen.c.
3847 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3849 * Fixed WIN32 configuration in the ./configure script.
3850 Fixed to include xti.h on environments that has it.
3851 Patches by Carsten Ilchmann and andrew.
3853 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3855 * Changed the silc_id_create_client_id to be collision
3856 resistant. It is now assured that there cannot be created
3857 two same client ID's. I suspect that some weird bugs in
3858 the server were actually caused by duplicate Client IDs.
3859 Affected file silcd/serverid.[ch]. A router receiving
3860 new ID now also assures and informs the sending server
3861 if the ID caused collision.
3863 * Changed the silc_id_create_channel_id to also assure that
3864 there are no collisions.
3866 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3868 * Statement about ignoring the Mutual Authentication flag when
3869 performing rekey with PFS was a bit misleading. It is ignored
3870 if it was set in the initial negotiation, it cannot be even
3871 set in the rekey. Fixed in the ke-auth draft. Started the
3872 new versions of the protocol drafts in the doc/.
3874 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3876 * Fixed a bug in silc_client_command_identify_save when saving
3877 new channel information. The channel name was no duplicated
3878 and caused crash on exit. Affected file is
3879 lib/silcclient/command_reply.c.
3881 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3883 * Fixed the getkey command handling in the server. Send just
3884 empty OK reply to the sender if the key could not be fetched
3885 (but everything else was ok, like the key just was not available).
3886 Changed the public key parameter to optional in the protocol
3887 specs so that empty OK reply can be sent. Affected file
3890 Added a message to Irssi SILC client to tell to user if the
3891 server did not return a public key.
3893 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3895 * Fixed a channel key regeneration bug. It registered new
3896 timeout tasks exponentially until all system resources were
3897 used. Affected file silcd/server.c.
3899 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3901 * Added the SILC Document generator to the scripts/silcdoc.
3902 It can be used to generate the Toolkit Reference Manual out
3903 of the source tree. Internally it will also use the RoboDoc
3904 generator now imported in util/robodoc.
3906 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3908 * Added couple of return's in rekey protocol if error orccurred
3909 during the protocol. The execution must be terminated.
3910 Affected file silcd/protocol.c. Also, terminate the protocol
3911 always with timeout.
3913 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3915 * The client's Client ID was created initally from the wrong
3916 nickname (it could have been in format nick@host) in the
3917 silc_server_new_client. Affected file silcd/packet_receive.c
3919 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3921 * Added some SILC_LOG_ERROR's to various error conditions
3922 if client could not be added to ID cache. Affected files
3923 silcd/packet_receive.c and silcd/server.c.
3925 * When client's sock->user_data is freed, NULL also the
3926 client->router and client->connection pointers. Added check
3927 for these pointers being NULL to various places around the
3928 code. Affected file silcd/server.c.
3930 * Added client->data.registered == TRUE checks to various
3931 places around the code to assure that unregistered client's
3932 are not handled when it is not allowed. Affected file
3935 * Added `bool registered' fields to all
3936 silc_idlist_[server|client]_get_* routines to indicate whether
3937 the fetched client needs to be registered or not. Affected
3938 file silcd/idlist.[ch].
3940 * Add your own entry as registered to the ID cache in the
3941 server. Affected file server.c.
3943 * Fixed a bug in silc_server_new_server. The SilcServer was
3944 set as the new server's context instead of SilcServerEntry.
3945 This naturally caused some weird bugs.
3947 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3949 * Do not delete the channel rekey task when adding it
3950 for in silc_server_create_channel_key.
3952 * Changed the silc_server_create_channel_key to return
3953 TRUE or FALSE to indicate the success of the channel key
3956 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3958 * Fixed MSVC++ project files and added missing files to
3959 Makefiles under win32/.
3961 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3963 * Do not add TCP_NODELAY flag if the operating system
3964 does not have it defined. Affected files are
3965 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3967 * Fixed buffer overflow from Irssi SILC Client. Affected
3968 file irssi/src/fe-common/core/themes.c.
3970 * Fixed double free in client library in the file
3971 lib/silcclient/client.c when disconnecting from server.
3973 * Applied double free patch from cras to Irssi SILC client.
3974 Affected files irssi/src/core/[modules/expandos].c
3976 * Fixed the disconnection handling to Irssi SILC Client.
3977 The application must call silc_client_close_connection
3978 in ops->connect client operation in case of failure of
3979 the connection. Affected file is
3980 irssi/src/silc/core/client_ops.c.
3982 * Do not set sock->protocol to NULL in the function
3983 silc_client_close_connection after executing the protocol's
3984 final callback since the sock might not be valid anymore.
3985 Affected file lib/silcclient/client.c.
3987 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3989 * Do not enable SILC_THREADS if the linking with libpthread
3990 did not happen. Affected file configure.in.pre.
3992 * Added notion to protocol specification that server must
3993 verify the sent authentication payload with CMODE when
3994 setting the channel founder key. Implemented it to the
3995 server. Affected file silcd/command.c.
3997 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3999 * Added _EXTRA_DIST SILC distribution variable to the
4000 distributions file. It is used to conditionally add extra
4001 files or directories to the specific distribution. Affected
4002 files ./prepare, Makefile.am.pre and distributions.
4004 Removed the `_' from the start of the distribution names.
4007 * Added README.WIN32 for instructions to compile the Toolkit
4010 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4012 * Fixed a double free in disconnection in the server. Affected
4013 file is silcd/server.c.
4015 * Fixed the lib/silcske/groups.c to work now also with GMP
4016 MP library. The string conversion did not work when using
4017 specific base and the base is indicated in the string as well.
4019 * Created win32/ directory which now includes MSVC++ specific
4020 stuff so that toolkit (DLLs) may be compiled with MSVC++.
4021 It will appear only in the toolkit distribution
4023 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4025 * Changed the key material distribution function in case when
4026 the hash output is too short. The data is now concatenated
4027 a bit differently than it used to. Made the change to the
4028 SKE protocol specification.
4030 * Added better GMP detection to configure.in.pre. A patch
4033 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4035 * Fixed a minor bug in SKE that might cause some problem on
4036 some platforms. Affected file lib/silcske/silcske.c.
4038 * Added the cookie checking for initiator in the SKE. It checks
4039 that the responder returns the sent cookie unmodified. The
4040 affected file is lib/silcske/silcske.c. Added new SKE
4041 error type INVALID_COOKIE that can be sent during the
4042 negotiation. Fixed some memory leaks as well.
4044 * Added the "invalid cookie" error message to Irssi SILC client's
4047 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4049 * Added `task_max' field to the SilcClientParams to indicate
4050 the maximum tasks the scheduler can handle. If set to zero,
4051 default values are used. Affected file lib/silcclient/silcapi.h.
4053 * Fixed memory leaks in silc_client_close_connection. Affected
4054 file lib/silcclient/client.c.
4056 * Added silc_client_del_client_entry to client library to free
4057 all memory of given client entry. Affected file is
4058 lib/silcclient/idlist.[ch].
4060 * Added new functions silc_client_del_channel and
4061 silc_client_del_server to delete channel and server entries.
4062 Affected file lib/silcclient/[silcapi.h/idlist.c].
4064 * Removed silc_client_del_client_by_id from silcapi.h.
4066 * Fixed the INFO command to return the server's own info
4067 correctly when querying by Server ID. Affected file is
4070 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4072 * Removed the non-blocking settings in WIN32 code in the
4073 silc_sock_[read/write] and added SleepEx instead. Affected
4074 file lib/silcutil/win32/silcwin32sockconn.c. The availability
4075 of input data is now checked with FIONREAD and ioctlsocket.
4077 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4079 * Call silc_schedule_task_del_by_context in the
4080 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
4081 Affected file lib/silccore/silcprotocol.c.
4083 * Call silc_protocol_cancel for active protocols in the
4084 silc_server_close_connection if the funtion
4085 silc_server_free_sock_user_data has not been called.
4086 Affected file silcd/server.c.
4088 * Generic tasks cannot be deleted using the del_by_fd
4089 task deleting function since generic tasks does not match
4090 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
4092 * Added a notion to SILCOPER help file that the SILCOPER works
4093 only on router server, not on normal server.
4095 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4097 * Added for WIN32 support for the new scheduler as well.
4098 Affected file lib/silcutil/win32/silcwin32schedule.c.
4100 * Fixed the SHA1 implementation to work on various platforms.
4102 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4104 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
4105 API. It is part of the scheduler now. Everything else is
4106 as previously but some functions has changed their names.
4107 Checkout the lib/silcutil/silcschedule.h for the interface.
4108 Updated all applications to use the new interface. Affected
4109 files are lib/silcutil/silcschedule.[ch].
4111 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4113 * Found a bug in the SKE implementation. The HASH value,
4114 specified by the protocol, was not computed correctly. The
4115 public key of the responder was not added to the computation
4116 even though it is mandatory. Affected file lib/silcske/silcske.c.
4117 This unfortunately causes incompatibilities with older
4118 clients and servers.
4120 * Added WIN32 specific network init and uninit functions:
4121 silc_net_win32_init and silc_net_win32_uninit to init and uninit
4122 the Winsock2. Affected file lib/silcutil/silcnet.h and
4123 lib/silcutil/win32/silcwin32net.c.
4125 * Set the socket always to nonblocking mode on WIN32 after
4126 reading data or writing data. Affected file is
4127 lib/silcutil/win32/silcwin32sockconn.c.
4129 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4131 * Fixed various compilation problems under WIN32. Affected
4132 files lib/silcutil/win32/silcwin32thread.c and
4133 lib/silcutil/win32/silcwin32schedule.c.
4135 * Removed all _internal.h #includes from public header
4136 files. Internal headers must never be included from
4139 Removed also the lib/silcske/payload_internal.h file.
4141 * All include files that may be needed (public and some others
4142 included by the public headers) by application developers are
4143 now copied to the ./includes directory. It does not copy any
4144 internal headers. Affected file Makefile.defines.pre and all
4145 Makefile.am's under lib/ and subdirs.
4147 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4149 * Do not change the ~/.silc directory's permissions automatically.
4150 Affected file irssi/src/silc/core/clientutil.c.
4152 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4154 * Do not cancel the protocol in silc_server_close_connection
4155 it might cause recursion. Now cancelled in the function
4156 silc_server_free_sock_user_data. Affected file silcd/server.c.
4158 * Fixed the silc_server_remove_clients_by_server to regenerate
4159 the channel keys correctly finally. Added also new function
4160 silc_server_remove_clients_channels to actually do it.
4161 Affected file silcd/server.c.
4163 * Fixed the silc_server_new_channel to not crash by giving
4164 wrong router to the new channel. Affected file is
4165 silcd/packet_receive.c.
4167 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4169 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
4170 which is given as argument to the silc_client_alloc now.
4171 It can be used to configure the client and set various parameters
4172 that affect the function of the client.
4174 * The USERS command in server did not check whether the channel
4175 is private or secret. Affected file silcd/command.c.
4177 * Added new argument to the USERS command in protocol specification.
4178 The USERS command now can take the channel name as argument
4179 as well. Added support for this in client and server and
4180 updated the protocol specs.
4182 * Completed the GETKEY command in client. It can be now used
4183 to fetch also servers public key not only some clients.
4184 Affected files lib/silcclient/command[_reply].c.
4186 * Added silc_client_get_server to return server entry by the
4187 server name. Affected files lib/silcclient/silcapi.h and
4190 * Redefined the IDENTIFY command in protocol specification to be
4191 more generic. It now can be used to query information about
4192 any entity in the SILC Network, including clients, servers and
4193 channels. The query may be based either the entity's name
4194 or the ID. Added support for this in both client and server.
4196 Affected files silcd/command.c and lib/silcclient/command.c
4197 and command_reply.c.
4199 * Optimized the WHOIS and WHOWAS commands in the server. Removed
4200 the _from_client and _from_server functions. Affected file
4203 * Added silc_client_get_channel_by_id_resolve to the file
4204 lib/silcclient/silcapi.h to resolve channel information by
4205 its ID. Added also silc_client_get_channel_by_id that
4206 does not resolve it from the server.
4208 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4210 * Added SilcServerEntry context into the client library
4211 to represent one server. The INFO command now allocates
4212 these to save the resolved server info. For now on the
4213 client library will also keep information about servers,
4214 connected and resolved with INFO.
4216 The INFO command now allocates the SilcServerEntry context
4217 and saves the server info there. The COMMAND_REPLY in
4218 the INFO now returns the parameters to application in
4219 same order as defined in the protocol specification.
4221 The entries are cached in the client->server_cache.
4223 * The INFO command is now issued after received the Client ID
4224 from the server. Affected file lib/silcclient/client.c.
4226 * The CMODE_CHANGE notify may now return also an SilcServerEntry
4227 to the application as the mode changer might be server.
4228 It is guaranteed that NULL is not returned anymore to the
4229 application. Affected file lib/silcclient/client_notify.c.
4231 The ID Type is now also passed to the application so that
4232 it can check whether the returned entry is SilcClientEntry
4235 Added new function silc_client_get_server_by_id to return
4236 the server entry by ID. Affected files are the
4237 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
4239 * Do not create the channel in the Irssi SILC Client when issuing
4240 the JOIN command but when received the sucessful JOIN command
4241 reply. Otherwise the channel might get created even though we
4242 could not join it. The Affected file is
4243 irssi/src/silc/core/[silc-channels.c/client_ops.c].
4245 * Fixed a channel joining bug in router. The router must also
4246 check the channel modes, invite and ban lists etc. when serving
4247 the JOIN command sent by normal server. Affected file is
4248 silcd/command.c. The router now resolves the client's
4249 information from the server who sent the JOIN command if it
4250 does not know it, and processes the JOIN command only after
4253 * Changed the SilcCommandCb to take new argument; void *context2.
4254 Affected file lib/silccore/silccommand.h
4256 The second argument in the command callbacks in the server now
4257 includes the SilcServerCommandReplyContext if the command was
4258 called as pending command callback from the command reply.
4259 Otherwise it is NULL. When called as pending the status of the
4260 command reply will be checked and if it was erronous the
4261 error will be sent to the original sender of the command.
4262 This way the client always receives the error messages even
4263 though the server was actually the one who received the error
4264 when it resent the command to router, for example. Affected
4265 files silcd/command[_reply].[ch].
4267 * Fixed sending WHOWAS command's error message to client if
4268 the requested client could not be found. It was missing.
4271 * Changed the CMODE and CUMODE commands reply arguments in the
4272 protocol specification. The Channel ID is now sent in both
4273 of the commands to identify the channel. Implemented this
4274 new feature to the client and server. Affected files
4275 lib/silcclient/command_reply.c and silcd/command.c.
4277 * Made better checks for invite and ban lists in the JOIN
4278 command in server. Affected file silcd/command.c.
4280 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4282 * The server now performs the incoming host IP/DNS lookup
4283 using the silc_socket_host_lookup and thus does not block
4284 the server anymore. Affected file silcd/server.c.
4286 * Completed the multi-thread support for SILC Scheduler in
4287 the lib/silcutil/silcschedule.c.
4289 * Fixed the configure.in.pre to detect the pthread correctly
4292 * Fixed a deadlock in silc_task_queue_wakeup in the file
4293 lib/silcutil/silctask.c.
4295 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4297 * Added new function silc_schedule_wakeup that is used in
4298 multi-threaded environment to wakeup the main thread's
4299 schduler. It needs to be used when a thread adds a new task
4300 or removes a task from task queues. After waking up, the
4301 scheduler will detect the task queue changes. If threads
4302 support is not compiled in this function has no effect.
4303 Implemented the wakeup mechanism to both Unix and WIN32
4304 systems. Affected files are lib/silcutil/silcschedule.[ch],
4305 lib/silcutil/unix/silcunixschedule.c and the
4306 lib/silcutil/win32/silcwin32schedule.c.
4308 * Added new function silc_task_queue_wakeup to wakeup the
4309 scheduler by the specified task queue. Affected file
4310 lib/silcutil/silctask.[ch].
4312 * The silc_socket_host_lookup_start now wakes up the scheduler
4313 after adding the timeout task. Affected file is
4314 lib/silcutil/silcsockconn.c.
4316 * The silc_socket_host_lookup is synchronous now if the threads
4317 support is not compiled in. However, the callback is still
4318 called asyncronously through the scheduler, anyway. Affected
4319 file lib/silcutil/silcsockconn.c.
4321 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4323 * Added new function silc_socket_host_lookup to perform
4324 asynchronous IP and FQDN lookups for the socket connection.
4325 Affected files lib/silcutil/silcsockconn.[ch].
4327 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4329 * Added SILC_MUTEX_DEFINE to define the mutex on environments
4330 that may or may not compile the mutex support in.
4332 Changed the silc_mutex_alloc interface. It allocates the
4333 mutex now to the sent pointer and returns TRUE or FALSE.
4335 Affected file lib/silcutil/silcmutex.h.
4337 * Wrote the SILC Task Queue interface to support multi-threads.
4338 Affected file lib/silcutil/silctask.[ch].
4340 * Wrote the SILC Scheduler to support multi-threads. Affected
4341 file lib/silcutil/silcschedule.c.
4343 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4345 * Implemented the SILC Mutex API and SILC Thread API for WIN32
4346 in lib/silcutil/win32/.
4348 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4350 * Defined SILC Mutex API and SILC Thread API and implemented
4351 them for Unix. Affected files are
4352 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
4353 lib/silcutil/unix/silcunixmutex.c and
4354 lib/silcutil/unix/silcunixthread.c.
4356 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4358 * Fixed the silc_server_remove_clients_by_server's channel
4359 key re-generation. The hash table handling was incorrect
4360 and would not work with many channels. Affected file is
4363 * Fixed some memory leaks around the server code.
4365 * Rewrote the silc_server_get_users_on_channel to support IPv6
4366 based Client ID's. Affected file silcd/server.c.
4368 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
4369 specification. However, a separate document must be written
4370 to define the detailed signing procedure and the payload
4371 associated with the flag. Defined the flag to the
4372 lib/silccore/silcchannel.h as well.
4374 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4376 * Changed the dynamic tables to static size tables in the
4377 lib/silccrypt/silchmac.c.
4379 * Removed GCC dependencies from the code. A patch by cras.
4381 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4383 * Do not show the error "Error receiving packet bla bla"
4384 in server if it really was not an error (-2 means that reading
4385 is pending). Affected file silcd/server.c.
4387 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4389 * Fixed a possible crash in silc_server_remove_clients_by_server
4390 in silcd/server.c. Fixed there also some memory leaks.
4392 * Fixed the silc_idlist_replace_client_id. It could replace
4393 wrong key in the hash table. Affected file silcd/idlist.c.
4395 * Do not check whether there are global users on the channel
4396 if the channel->global_users is FALSE. Affected functions
4397 silc_server_remove_from_one_channel and
4398 silc_server_remove_from_channels in silcd/server.c. Also,
4399 do not check if the removed client is local as we can be
4400 sure that global client was not removed from the channel
4401 and checking for global users is not needed.
4403 * The silc_server_remove_clients_by_server now re-generates
4404 the channel keys correctly for those channels that had
4405 clients removed from them. Affected file silcd/server.c.
4407 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4409 * Found the reason of random crashes in the server. We weren't
4410 ignoring the SIGPIPE signal (which can be sent in write())
4411 and it crashed the server. Affected file silcd/silcd.c.
4413 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4415 * Assure that sock->user_data is not NULL in the function
4416 silc_server_packet_send in silcd/packet_send.c.
4418 * Disconnect the remote connection if it could not be added
4419 to any ID lists in the server. The affected file is
4422 * Check in silc_server_packet_send[_real/dest] that the
4423 socket is not disconnecting and ignore the data if it is.
4424 Affected file silcd/packet_send.c.
4426 * Define inline to __inline on native WIN32 compilation.
4427 Affected file includes/silcwin32.h.
4429 * Added some explicit type casts for inline code since MSVC
4430 require them. Affected files lib/silcutil/silcbuffer.h,
4431 lib/trq/silcdlist.h and lib/trq/silclist.h.
4433 * Print warning in log files from now on if the packet
4434 decryption fails. Affected file silcd/server.c.
4436 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4438 * Changed the `say' client operation's interface to accept
4439 new `type' argument to indicate the type of the message sent
4440 by the library. The application may filter the library's
4441 messages according the type. The affected file is the
4442 lib/silcclient/silcapi.h.
4444 * Added two new functions to lib/silcclient/silcapi.h:
4445 silc_client_del_client and silc_client_del_client_by_id.
4446 Affected file lib/silcclient/idlist.c.
4448 * Moved the clientincludes.h from includes/ to silc/ and
4449 serverincludes.h from includes/ to silcd/.
4451 * The modes for the CMODE and CUMODE are now passed as
4452 uint32 for application with COMMAND_REPLY. The affected
4453 file is lib/silcclient/command_reply.c.
4455 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4457 * /WHOIS without arguments shows client's own information.
4458 Affected file lib/silcclient/command.c.
4460 * Changed PING to not accept any arguments. The specs
4461 says that client can ping only the connected server so
4462 requiring an argument is not needed. Affected file is
4463 lib/silcclient/command.c.
4465 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4467 * Fixed a fatal bug in private message sending and reception
4468 encryption and decryption when using private message keys.
4469 The implementation was incorrect and did not follow the
4470 specification. It causd that some of the message were
4471 lost since it did not use the sending and receiving keys
4472 as the protocol suggests. This has been fixed and will cause
4473 incompatibilities with older clients when sending private
4474 message encrypted with private message keys. Affected files
4475 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
4476 and various other in Irssi SILC Client.
4478 Added `responder' boolean argument to the functions
4479 silc_client_add_private_message_key[_ske] to indicate when
4480 the key is added as responder or initiator of the key
4483 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4485 * Removed the silc_ske_check_version function and created
4486 a SilcSKECheckVersion callback. Added also a function
4487 silc_ske_set_callbacks that is now used to set all SKE
4488 callbacks. The callback functions are not given to
4489 the SKE functions anymore, but this function is used to
4492 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
4494 * Added `silc_version' argument to the silc_client_alloc
4495 to define the version of the application for the library.
4496 The library will use the version string to compare it
4497 against the remote host's (usually a server) version
4498 string. Affected file lib/silcclient/silcapi.h
4500 * Added the KE protocol context to Key Agreement context
4501 in client library so that we can abort the SKE if it
4502 is in process when we get timeout. Affected file is
4503 lib/silcclient/client_keyagr.c.
4505 * Do not resolve the client ID forever if it returns in the
4506 first time that such client does not exist. This was done
4507 for example with private message. Affected file is
4508 lib/silcclient/client_prvmsg.c.
4510 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4512 * Do not add regex.h for WIN32. The affected file
4513 includes/silcincludes.h.
4515 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
4516 not work yet 100%. It generates the DLL's automatically
4517 when compiling with --with-win32 under cygwin.
4519 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4521 * lib/contrib/regex.c is not compiled on WIN32.
4523 * Added silc_net_get_socket_opt function to the
4524 lib/silcutil/silcnet.h.
4526 * Added includes/silcwin32.h for WIN32 specific includes
4529 * Do not use ptime structure or any of the posix process
4530 functions on WIN32 in lib/silccrypt/silrng.c.
4532 * Added silc_gettimeofday to provide generic function
4533 for struct timeval on all platforms. Added the function
4534 to lib/silcutil/silcutil.h.
4536 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4538 * Moved the lib/silccore/silcsockconn.[ch] to the utility
4539 library as they clearly belong there. As a plus side we
4540 can make the actual socket connection routines platform
4543 Added also new generic function silc_socket_read and
4544 silc_socket_write (that used to be silc_packet_[read/write].
4545 The implementation of these are platform specific.
4547 * Added WIN32 specific routines of silc_socket_[read/write]
4548 to lib/silcutil/win32/silcwin32sockconn.c.
4550 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4552 * Added preliminary support for native WIN32 compilation under
4553 cygwin (using the -mno-cygwin option for GCC) to the
4554 ./configure.in.pre. The --with-win32 now prepares the
4555 compilation for native WIN32.
4557 * Rewrote the SILC Scheduler interface in the file
4558 lib/silcutil/silcschedule.h. The scheduler is now context
4559 based and does not have anymore any global static scheduler.
4560 Moved the Unix scheduler to the lib/silcutil/unix/ directory
4561 and created lib/silcutil/win32 directory for WIN32 based
4564 * Added Unix specific network routines to the
4565 lib/silcutil/unix/silcunixnet.c and the old
4566 lib/silcutil/silcnet.c includes now only generic routines.
4568 Added WIN32 specific network routines to the
4569 lib/silcutil/win32/silcwin32net.c.
4571 * Added Unix specific utility functions from the
4572 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
4574 * Added WIN32 SILC Scheduler to the file
4575 lib/silcutil/win32/silcwin32schedule.c. The code is of course
4578 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4580 * Do not handle JOIN notify in the server if the target client
4581 is not registered (idata->registered == FALSE). The affected
4582 file is silcd/packet_receive.c.
4584 * Update the nickrec->founder in event_cumode in the Irssi SILC
4585 client. Affected file irssi/src/silc/core/silc-channels.c.
4587 * Fixed the CUMODE_CHANGE notify handling in the server when
4588 server and router are announcing their clients on channels.
4589 Now the mode changes are saved and notified correctly. The
4590 affected file is /silcd/packet_receive.c.
4592 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
4593 They really did not replace the cache entry in the ID Cache.
4594 Now they do that. Affected file silcd/idlist.c.
4596 * Fixed the KICK notify handling in the Irssi SILC client to
4597 update the channel records so that the kicked client does not
4598 appear to be on the channel. The affected file is
4599 irssi/src/silc/core/silc-channels.c.
4601 * Always update the conn->current_channel when executing command
4602 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
4604 * Fixed the KILL notify handling in Irssi SILC client to remove
4605 the killed client on all channels.
4607 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4609 * Fixed the silc_parse_command_line to remove extra spaces
4610 from the start and end of the arguments. Affected file is
4611 lib/silcutil/silcutil.c.
4613 * Cancel and free any active protocol in the function
4614 silc_server_close_connection. Affected file silcd/server.c.
4616 * Cancel and free any active protocol in the function
4617 silc_client_close_connction. Affected file is
4618 lib/silcclient/client.c.
4620 * Do not execute the KILL command for clients that are in
4621 history (ie. they are not in the network). Affected file is
4624 * Fixed KILL notify handling, client does not crash anymore.
4625 Affected file irssi/src/silc/core/silc-channels.c.
4627 * Reduced the default packet buffer size from 2048 to 1024 in
4628 lib/silccore/silcpacket.c.
4630 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
4631 counter to the SKE context that is incresed when the SKE library
4632 performs async operation outside the library. If the outside
4633 process frees the SKE context and FREED status will be set
4634 and the library will detect after the sync operation that the
4635 libary is freed. The affected files are
4636 lib/silcske/silcske[_status].[ch].
4638 * Resolve the client entry information in the function
4639 silc_client_channel_message to assure that NULL pointer is not
4640 passed as client entry to the application. */
4642 * Fixed the task timeout calculation to assure that there is
4643 never negative timeouts. The affected file is
4644 lib/silcutil/silcschedule.c.
4646 * Fixed the channel user mode notification sending in server.
4647 It was sent point-to-point to the router (or to server by router)
4648 but it needs to be destined to a channel. The routines now
4649 supports sending the channel user mode notifys to the channels
4650 when announcing clients and channels. Affected files are
4651 silcd/server.c and silcd/packet_receive.c.
4653 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
4654 It did not actually replace the old channel entry in the cache.
4655 Affected file lib/silcclient/client_notify.c.
4657 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4659 * Fixed a possible crash in silc_packet_send_prepare. It now
4660 assures always that there is enough space in the buffer and
4661 at the tail area of the buffer (for MAC).
4663 Fixed the inbound buffer reallocation in silc_packet_read.
4664 It was old code and did not handle the reallocation correctly.
4667 The affected file is lib/silccore/silcpacket.c.
4669 * Fixed buffer overflow in silc_parse_nickname in the file
4670 lib/silcutil/silcutil.c.
4672 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4674 * make install generates new server keys only if there is not
4677 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4679 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
4680 Added check that if the NOREPLY is set then we will not send
4681 the away message. This avoids infinite loop of away messages
4682 if both clients are away. The affected file is
4683 lib/silcclient/client_prvmsg.c.
4685 * Fixed client crash if /NICK was given without arguments.
4686 Affected file lib/silcclient/command.c.
4688 * Server does not send the invite list in INVITE command back
4689 to the client if the list was not altered. Added this notion
4690 to the protocol spec as well. Affected file silcd/command.c.
4692 Fixed possible crash in INVITE command by checking the
4693 value of silc_server_get_client_route command.
4695 * Fixed the INVITE notify type handling. The arguments are now
4696 taken in correct order and client does not crash. The affected
4697 file is irssi/src/silc/core/silc-channels.c.
4699 Removed the "Inviting xxx to channel" message from the
4700 client library away and let the application handle it.
4701 Affected file lib/silcclient/command.c. Added that message
4702 to Irssi SILC client's message formats.
4704 * Fixed CMODE command crash in client. It now checks the
4705 amount of arguments correctly and does not crash. The affected
4706 file is lib/silcclient/command.c.
4708 * Do not create new channel automatically in silc_channels_join
4709 but check whether the channel by that name already exists.
4710 Affected file irssi/silc/core/silc-channels.c.
4712 * Do not send the SERVER_SIGNOFF to router if the disconnected
4713 entity was the router. Affected file silcd/server.c.
4715 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
4716 SILC client as it was missing from there.
4718 Added the handling of the KICK notify to the Irssi SILC client
4719 as it was missing. Added "you have been kicked" message to
4720 Irssi SILC client's message modules formats.
4722 Added the handing of the KILL notify to the Irssi SILC client
4723 as it was missing. Added the kill message module formats
4726 The affected file is irssi/src/silc/core/silc-channels.c.
4728 * The router did not save the channel mode the server announced.
4729 Affected file silcd/packet_receive.c.
4731 * Fixed a possible crash in INFO command in server. If the
4732 server did not provide the server info it crashed. Affected
4733 file silcd/command.c.
4735 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4737 * Fixed the GETKEY command in the server to check also the
4738 global list. Otherwise the GETKEY would not work correctly
4739 in normal SILC server. Affected file silcd/command.c.
4741 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4743 * Fixed GETKEY crash, it crashed if the command did not succseed.
4745 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4747 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
4748 is now real and not just an macro interface to GMP.
4750 Removed the entire GMP from the source tree and imported new
4751 NSS MPI library instead. Reason for removing GMP is that it is
4752 extremely large and compiles extremely slow. The NSS MPI
4753 is only a few files and compiles in less than 10 seconds.
4754 The speed is also about the same as GMP. The MPI is imported
4755 to lib/silcmath/mpi.
4757 If the system has GMP installed we will still use the GMP.
4758 If it is not then the NSS MPI will be compiled.
4760 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4762 * Merged a long nickname (127 characters long) crash bugfix from
4763 Irssi CVS tree. Affected file irssi/src/core/misc.c.
4765 * Merged a freed memory reference bugfix from Irssi CVS tree.
4766 Affected file irssi/src/core/commands.c.
4768 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4770 * Added the server's public key sving and verification to the
4771 server when performing the SKE. This was missing and the
4772 remote server's (or router's) public key was accepted without
4773 checking whether we have it previously or trust it at all.
4774 Affected file silcd/protocol.c.
4776 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4778 * Check in the silc_server_timeout_remote if protocol is active
4779 and make sure that the protocol's final callback is called so
4780 that all memory if freed. Affected file silcd/server.c.
4782 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4784 * silc_server_whois_send_reply crashed the server if the nickname
4785 was 127 characters long. Affected file silcd/command.c.
4787 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4789 * Added sanity check to the silc_server_new_client. If the hostname
4790 is provided inside username then check that the provided hostname
4791 really is the same as the resolved one. If the hostname was not
4792 resolved then check it from the public key. Affected file is
4793 silcd/packet_receive.c.
4795 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
4796 if the server disconnected us and the connection is not valid
4797 anymore. Affected file irssi/src/silc/core/silc-channels.c.
4799 * Moved the silc_client_[chmode|chumode|chumode_char] away from
4800 the library to the lib/silcutil/silcutil.[ch].
4802 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4804 * Close log file after open. Affected file
4805 lib/silcutil/silclog.c.
4807 * Check whether sock == NULL in silc_client_send_packet and return
4808 if it is. Affected file lib/silcclient/silcclient.c.
4810 * Check rec->entry == NULL in the Irssi SILC Client before
4811 sending the channel message. Affecte file is
4812 irssi/src/silc/core/silc-servers.c.
4814 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4816 * Merged a splitted window bugfix from Irssi CVS tree. The
4817 affected file is irssi/src/fe-text/textbuffer-view.c.
4819 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
4820 It did not print nickname.
4822 * Improved the distributions system a bit.
4824 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4826 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
4827 irssi/src/fe-text/gui-window.c.
4829 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
4830 to in-active server. The affected file is
4831 irssi/src/silc/core/client_ops.c.
4833 * Resolve the client in USERS command reply if the entry does
4834 not have username resolved. The affected file is
4835 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
4836 command to WHOIS command to really resolve stuff. The USERS
4837 is not used any more in any critical section so WHOIS can
4838 be used even though it might be slower than IDENTIFY.
4840 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
4843 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4845 * Changed the protocol API a bit more consistent in the
4846 lib/silccore/silcprotocol.[ch].
4848 * Changed the following headers to ROBODoc format:
4850 lib/silccore/silcpayload.h
4851 lib/silccore/silcprotocol.h
4852 lib/silccore/silcsockconn.h
4854 All core library headers are now formatted.
4856 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4858 * Fixed a bug in Irssi SILC client; do not show that you are
4859 server/router operator if you really are not. Affected file is
4860 irssi/src/silc/core/client_ops.c.
4862 * Renamed silc_command_free_payload to silc_command_payload_free.
4863 Affected file lib/silccore/silccommand.h
4865 * Added silcmath.h to include the prototoypes of various routines
4866 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
4869 * Changed the following headers to ROBODoc format:
4871 lib/silccore/silcchannel.h
4872 lib/silccore/silccommand.h
4873 lib/silccore/silcid.h
4874 lib/silccore/silcidcache.h
4875 lib/silccore/silcmode.h
4876 lib/silccore/silcnotify.h
4877 lib/silccore/silcpacket.h
4878 lib/silcmath/silcmath.h
4880 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4882 * Added checking to the server code not to start the server if
4883 ciphers and stuff are not configured properly. Affected files
4884 silcd/serverconfig.[h] and silcd/server.c.
4886 * Changed the layout of the header files of the public interfaces
4887 in the SILC libraries. The new layout supports ROBODoc
4888 documentation tool (and some others) so that it is easy to create
4889 a library reference manual. All the other headers and source
4890 code must still follow the CodingStyle document. Also source
4891 code must not include these ROBODoc stuffs, only the headers.
4892 Furthermore, all public interface headers must now be named
4893 by using `silc' prefix, example: silcapi.h, silccipher.h.
4894 Some files were renamed due to this. All the other headers
4895 must not be used as public interfaces. I will update the
4896 CodingStyle document later. Changed following headers, so far:
4898 lib/silcclient/silcapi.h
4899 lib/silccore/silcauth.h
4900 lib/silccore/silcprivate.h
4901 lib/silccrypt/silcdh.h
4903 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4907 * Removed silc_client_packet_send_flush from the client library
4908 as it is not needed. Affected file lib/silcclient/client.[ch].
4910 * Added printing of message of unresolved authentication method
4911 to the Irssi SILC client. Added it to the module formats.
4912 Removed the same message from the client library.
4914 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4916 * Added new distribution feature, DISTLABEL. Every distribution
4917 can define own preprocessor label that can be used in the
4918 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
4919 file distributions, acconfig.h.pre and prepare.
4921 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4923 * Added Makefile.defines_int to include the actual definitions
4924 for Makefile.defines.in. Tested the new distribution system,
4925 created distributions and tested installation.
4927 * Added AWAY message printing to the Irssi SILC client. Added
4928 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
4930 * Added SCONNECT command to call the SILC's CONNECT command.
4931 Cannot use CONNECT directly since Irssi uses that internally.
4932 Affected file irssi/src/silc/core/silc-servers.c.
4934 Added ACTION local command. It is same as ME command but takes
4935 the channel as mandatory argument.
4937 Rewrote some of the Irssi's help files to suite for SILC
4940 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4942 * Added Makefile.defines[.in] that should for now on be included
4943 in all Makefile.am file in the source tree. That file includes
4944 all common compilation definitions for SILC source tree.
4946 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4948 * Minor changes to the ./prepare script to change the package
4949 name according the distribution name to the configure.in.
4951 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4953 * Created new distribution system. Added file `distributions'
4954 that defines all the distributions that can be created out of
4955 the SILC source tree. The ./prepare script now reads that
4956 file to determine how to prepare the distributions. The
4957 first argument to the ./prepare is the name of the distribution
4958 and second is the version of the distribution. If given
4959 without arguments it creates the default (toolkit) distribution
4960 with the default version (defined in ./prepare).
4962 All Makefile.am files that are subject to the distributions
4963 are now named as Makefile.am.pre. These are ./Makefile.am
4964 and lib/Makefile.am. Others may be changed later.
4966 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4968 * Added invite list, ban list, some key management and connection
4969 error message printing to module formats in the Irssi SILC client.
4971 * Added new silc_client_set_away_message to set the away message
4972 that is back to the person who sent private message. The
4973 affected file lib/silcclient/silcapi.h and the
4974 lib/silcclient/client_prvmsg.c.
4976 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4978 * Fixed the private message sending in the Irssi SILC client,
4979 added local command KEY to the Irssi SILC client.
4981 Added key management and key agreement message formats to the
4982 irssi/src/fe-common/silc/module-formats.[ch].
4984 Added USERS (alias WHO) printing, server/router operator
4985 indication and LIST command printing to the module formats.
4987 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4989 * Fixed channel joining notify handling, cumode notify handling
4990 from Irssi SILC client.
4992 * Added SILC specific module-formats to the Irssi SILC client so
4993 that SILC specific message hilighting, colors etc is possible.
4994 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4996 Added channel mode, channel user mode, actions, notices,
4997 whois and whowas printing to the the module-formats.c.
4999 * Fixed a bug in channel deletion in the server. The channel
5000 is not left to the cache even if the channel founder auth mode
5001 is set when there are no users anymore on the channel. Affected
5002 file silcd/server.c.
5004 * The silc_net_localhost now resolves the entire hostname including
5005 the domain name. Affected file lib/silcutil/silcnet.c.
5007 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5009 * Changed the ask_passphrase client operation to be ascynchronous.
5010 It has now a completion callback and a context that the
5011 application must call after it has got the passphrase from
5012 the user. Affected files lib/silcclient/silcapi.h,
5013 lib/silcclient/protocol.c, lib/silcclient/command.c and
5016 Added SilcAskPassphrase callback that the application calls
5017 to deliver the passphrase to the library.
5019 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
5020 The public key verification and especially a certificate
5021 verification is asynchronous procedure.
5023 Added new SILC_SKE_STATUS_PENDING status to indicate the
5024 request is pending and a callback will be called to finalize
5027 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
5028 indicate that remote end did not send its public key (or
5029 certificate), even though we require it. Added check for this
5030 condition in the SKE. This was a security bug, now fixed.
5032 Defined new SilcSKEVerifyCbCompletion callback that is called
5033 when the verification process is completed.
5035 The affected files lib/silcske/silcske_status.h and
5036 lib/silcske/silcske.[ch].
5038 * Changed the verify_public_key client operation to be async
5039 as well. Defined SilcVerifyPublicKey callback that is used to
5040 indicate the success of the public key verification process.
5042 Changed the server and client to use the new async client
5045 * Changed the Irssi SILC client's internal scheduler to be called
5046 twice as many times as it used to be. As a result the client
5047 should be a bit faster now. Affected file is
5048 irssi/src/silc/core/silc-core.c.
5050 * Added support to Irssi SILC client of asynchronous public key
5051 verification and passphrase inquiry. Affected file is
5052 irssi/src/silc/core/silc-core.c.
5054 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5056 * Do not say "You have left channel %s" in client library.
5057 Moved it to the application. Affected files are
5058 lib/silcclient/command.c and silc/client_ops.c.
5060 * Fixed silc_client_get_clients. Command context was not
5061 duplicated and was freed memory in the callback. Affected
5062 file lib/silcclient/idlist.c.
5064 * Do not say "you are now talking..." on JOIN command in the
5065 client library. The appliation must handle it.
5067 * Do not say ".. changed topic to" in command reply in the
5068 client libary. The application must handle it.
5070 * Fixed TOPIC command sending in the client library.
5072 * Fixed a memory leak in silc_client_command_free in the file
5073 lib/silcclient/command.c.
5075 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5077 * Imported a modified version of Irssi client to the source tree.
5078 The Irssi will be used to create a new client called
5079 Irssi SILC. Imported to irssi/.
5081 Added silc_core_init_finish function to the Irssi. Affected
5082 file irssi/configure.in.
5084 A lot changes in the Makefile.ams around the irssi tree.
5086 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5088 * Do not rehash if the new size is same as the old size of the
5089 hash table, in the silc_hash_table_rehash*. The affected file
5090 lib/silcutil/silchashtable.c.
5092 * Replaced hash_table_del_by_context calls from the server
5093 (when channel->user_list and client->channels) to the
5094 hash_table_del as it is sufficient and faster.
5096 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5098 * Added silc_hash_table_list, silc_hash_table_get and the
5099 SilcHashTableList structure to provide an alternative way to
5100 traverse the hash table. The affected files are
5101 lib/silcutil/silchashtable.[ch].
5103 * Changed the server's idlist routines to use the hash table
5104 routines to optimize the code.
5106 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5108 * Replaced the client entry's `channel' list and channel entry's
5109 `user_list' list to hash tables for optimized lookup. Changed
5110 the code to use the hash table interface around the code.
5111 Affected file lib/silcd/idlist.[ch].
5113 * Added `auto_rehash' boolean argument to the function
5114 silc_hash_table_alloc to indicate whether the hash table should
5115 auto-rehash when it thinks is appropriate time. It will
5116 increase the hash table size if the there is twice as much
5117 entries in the table than the size of the table, and will
5118 decrease the size if there are twice as less entries than
5119 the size of the table.
5121 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5123 * Fixed silc_xxx_get_supported to not crash at some circumstances.
5125 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5127 * silc_idcache_purge_by_context deletes the entry now by context
5128 as it is supposed to do. Affected file lib/silccore/idcache.c.
5130 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
5131 client is not anymore valid (WHOWAS givens the info) and not
5132 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
5134 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5136 * Removed the `data' and `data_len' arguments from the ID Cache
5137 interfaces and added `name' argument. ID Cache does not handle
5138 anymore the binary data only a names associated with given ID.
5140 * When hashing a Client ID with silc_hash_id the entire ID is
5141 not hashed anymore, instead only the hash of the Client ID is
5142 hashed. This way we can access the Client ID from the cache
5143 with Client ID but with the hash of the ID (which is a hash of
5144 the nickname) as well without any difference in performance.
5146 Added also silc_idcache_find_by_id_one_ext to do one on one
5147 searching when we have the actual ID. Added also function
5148 silc_hash_client_id_compare. The affected files are
5149 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
5151 * When hashing the name associated with a ID it is always done
5152 in lowercase. This way we can access the cache without worrying
5153 about case-sensitivity, even though, for example nicknames are
5156 * Fixed a bug in server with channel message sending. It put
5157 wrong ID type as destination ID. The affected file
5158 silcd/packet_send.c.
5160 * silc_idcache_del_by_context now deletes from all hash tables
5161 by context. Affected file lib/silccore/idcache.c.
5163 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5165 * Changed the client library to use the new ID Cache interface.
5166 Changes around the source tree.
5168 * Added silc_hash_table_rehash_ext to rehash with specific
5169 hash function. Affected file lib/silcutil/silchashtable.[ch].
5171 * Added silc_hash_string_compare to compare two strings in the
5172 hash table. Affected file lib/silcutil/silcutil.[ch].
5174 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5176 * Added new function silc_idcache_del_by_context into the
5177 lib/silccore/idcache.[ch].
5179 * Changed the server's ID list routines to use the new ID Cache
5180 interface. Changes around the source tree.
5182 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5184 * Added silc_hash_table_del[_by_context]_ext functions in to the
5185 lib/silcutil/silchashtable.[ch].
5187 Removed silc_hash_table_find_all* routines and added new
5188 silc_hash_table_find_foreach to replace them.
5190 Added silc_hash_table_replace_ext function as extended
5191 replacing function. Separated the simple hash table interface
5192 from the extended hash table interface in the file
5193 lib/silcutil/silchashtable.h.
5195 * Fixed minor bugs and changed it to use some of the new
5196 hash table functions in lib/silccore/idcache.c
5198 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5200 * Added new function silc_hash_table_find_all to return all keys
5201 in the hash table by the specified key. As the hash table is
5202 collision resistant it also makes it possible to have several
5203 duplicate keys in the hash table. This function may be used to
5204 find all of the keys from the hash.
5206 Added user_context arguments to the SilcHashFunction,
5207 SilcHashCompare and SilcHashDestructor to deliver user specified
5210 Added new fuctions silc_hash_table_find[_all]_ext to do
5211 extended lookup with specified hash and compare functions and
5212 specified user contexts.
5214 Added new function silc_hash_table_add_ext to add the key
5215 with specified hash function and user context.
5217 Added new function silc_hash_table_foreach to traverse all
5218 entrys in the hash table. Added SilcHashForeach callback
5221 Added new function silc_hash_table_del_by_context to delete
5222 the entry only if the context associated with the key matches.
5224 Affected files are lib/silcutil/silchashtable.[ch].
5226 * Removed silc_hash_[server/client/channel]_id and added just
5227 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
5228 silc_hash_id_compare to compare two ID's using as the hash table
5229 comparison function. Added also silc_hash_data to hash
5230 binary data and silc_hash_data_compare to compare it.
5232 * Removed silc_idlist_find_client_by_hash as it is not needed
5233 anymore. Affected file silcd/idlist.[ch].
5235 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
5236 to use internally the SilcHashTable. The new ID Cache is a lot
5237 faster than the old one. Some of the ID Cache interface was also
5238 rewritten and obsolete and stupid functions were removed.
5240 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5242 * Added entry_count field to the SilcHashTable to keep the number
5243 of the entries in the table. Implemented the function
5244 silc_hash_table_rehash. Added new function
5245 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
5247 Fixed a minor bug in silc_hash_table_free.
5249 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
5250 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
5251 into the lib/silcutil/silcutil.[ch].
5253 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5255 * Implemented a collision resistant hash table into the
5256 lib/silcutil/silchashtable[ch]. See the header and the source
5257 for the SilcHashTable API.
5259 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5261 * Merged dotconf version 1.0.2 into lib/dotconf.
5263 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5265 * Do not compile anything in lib/silcsim/* if the SIM support
5266 is not enabled. The tree should now compile without problems
5269 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5271 * Compiled the SILC under cygwin. Compiled and tested briefly
5272 without problems. More tests needed. The SIMs didn't compile
5275 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
5277 * Fixed possible crash in silc_get_username in the
5278 lib/silcutil/silcutil.c.
5280 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5282 * Fixed a va_arg in silc/client_ops.c.
5284 * Oops, RC5 routines were named AES and caused some problems
5285 when not using SIM's. Affected file lib/silccrypt/rc5.c.
5287 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5289 * Added new SilcIDIP structure into the lib/silccore/id.h and
5290 replaced the old `ip' fields from all SILC ID's to that type.
5291 This is a step towards IPv6 support.
5293 The silc_id_get_len takes now the ID as an extra argument.
5294 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
5295 both IPv4 and IPv6 based ID's.
5297 The affected files are lib/silccore/id.[ch] and other files
5298 around the tree using these routines.
5300 * Removed the ID length arguments in server from various
5301 silc_server_send_notify_* routines -> they are not needed
5304 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5306 * Fixed memory leak in silc_encode_pem_file in the file
5307 lib/silcutil/silcutil.c.
5309 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5311 * Check minor version as well in the SKE. Affected files are
5312 silcd/protocol.c and lib/silcclient/protocol.c.
5314 * Added --identifier option to the server so that an identifier
5315 can be when creating the public key for the server. Affected
5316 file is silcd/silcd.c.
5318 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
5319 lib/silccrypt/silcpkcs.c.
5321 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5323 * Register default ciphers and stuff when using -C option with
5324 the server. Affected file sildc/silcd.c.
5326 * Put back the servers public key filename format, it is better
5327 than the new one. For now, the client keys are saved with the
5328 new filename format. The affected file silc/client_ops.c.
5330 * Implemented the Cipher API for the rest of the ciphers that
5331 did not implement it or implemented it the wrong way.
5333 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5335 * Register default ciphers and stuff when using the -S option
5336 in the client. Affected file silc/silc.c. Same also when
5337 creating new key pair with -C option.
5339 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5341 * Fixed the silc_verify_public_key client operation function to
5342 save the public keys differently. The fingerprint is now
5343 used as filename and not the hostname. This way also the
5344 client keys are saved uniquely and not with hostnames. The
5345 affected file is silc/client_ops.c.
5347 * Trimmed the silc_hash_fingerprint function to remove extra
5348 whitespaces from the end of the fingerprint. The affected
5349 file is lib/silccrypt/silchash.c.
5353 * Added silc_cipher_register_default function to register all
5354 default ciphers. It can be used when configuration files
5355 does not exist and the application does not want any specific
5356 ciphers in any specific order.
5358 The SilcDList is now used as silc_cipher_list dynamically
5359 allocated cipher list. Removed the static list all together
5360 and now all ciphers must be allocated to the dynamic list.
5361 The silc_cipher_alloc routine was changed to check only the
5364 All silc_cipher_* routines that used to return int returns
5367 The affected files lib/silccrypt/silccrypt.[ch].
5369 * The same thing was done to silc_hash_* as for silc_cipher_*
5370 routines. Affected files lib/silccrypt/silchash.[ch].
5372 * The same thing was done to silc_pkcs_* as for silc_cipher_*
5373 routines. Affected files lib/silccrypt/silcpkcs.[ch].
5374 Added also silc_pkcs_[un]register[_default] functions.
5375 Removed the data_context from the PKCS API.
5377 * Added silc_hmac_register_default function to register default
5378 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
5379 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
5380 to unregister all hmacs at once.
5382 * Register the default ciphers, hash functions, PKCSs and HMACs
5383 if client's configuration file does not exist. The affected
5386 * The client did not load the hash functions from the SIM
5387 modules at all. Added support for this. Affected file is
5388 silc/clientconfig.c.
5390 * When decoding public key with silc_pkcs_public_key_decode, check
5391 the supported algorithm only if PKCS are registered. Affected
5392 file lib/silccrypt/silcpkcs.c. The same was done with the
5393 silc_pkcs_private_key_decode.
5395 * Fixed the SILC List routines to keep the list always in order.
5396 It used to change the list's order when traversing the list but
5397 not it preserves the order. Affected file lib/trq/silclist.h.
5399 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5401 * Added the client library to use the SilcSocketConnection's
5402 reference counter (by silc_socket_dup) to prevent the bug that
5403 the socket object may be freed underneath async operation.
5405 * The name resolv library checking fixes in the configure.in.pre.
5408 * Created new version of the protocol drafts for future
5409 development. The -03 drafts are the ones that will be changed
5410 in the trunk now and the -02 will remain as they are.
5412 * Send list of CUMODE notifys to the router when announcing
5413 the channel users to the router. Affected file silcd/server.c.
5414 If the router receiving channel founder CUMODE for a channel
5415 that already has channel founder it will send CUMODE notify
5416 to the sender to remove the channel founder rights from the
5417 announced client. Affected file silcd/packet_receive.c.
5419 * The CUMODE notify may now use Server ID as well as the entity
5420 who changes the mode. Updated protocool specs.
5422 * Updated INSTALL and README files.
5424 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5426 * New web pages in the http://silc.pspt.fi. The pages was
5431 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5433 * Implemented the [DenyConnectin] config section in the server.
5434 Added silc_server_config_denied_conn to check whether incoming
5435 connection is denied. Affected file silcd/serverconfig.[ch].
5437 * Do not check the ports when checking the incoming configuration
5438 data if the port is 0, meaning any. Affected file is
5439 silcd/serverconfig.c.
5441 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5443 * Fixed buffer overflow in silc_string_compare in the file
5444 lib/silcutil/silcutil.c.
5446 * Fixed double free in silc_server_command_leave in the file
5449 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5451 * Fixed the version checking in the server. Affected file is
5454 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5456 * Fixed the configuration data fetching when accepting new
5457 connections in the server. Affected file silcd/server.c.
5459 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5461 * Added `sender_entry' argument to the function
5462 silc_server_packet_relay_to_channel so that we can check
5463 whether some destination actually belongs to the same route
5464 the sender belongs (ie, we must not resend the packet to the
5465 sender). Affected file silcd/packet_send.[ch].
5467 * Added `servername' field to the SilcClientEntry in the server
5468 to hold the name of the server where client is from. Affected
5469 file is silcd/idlist.h.
5471 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5473 * Moved the channel message encrypting in the router betwen
5474 router connections from silc_server_channel_message to the
5475 silc_server_packet_relay_to_channel since we want to check
5476 whether we have anybody channel before encrypting anything.
5477 Affected files silcd/packet_[receive/send].c.
5479 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5481 * Fixed the [AdminConnection] server config section to support
5482 multiple entries. Affected file silcd/serverconfig.c.
5484 * Added support into the server to check the validity of the
5485 incoming connection before executing any KE or authentication
5488 * The connection configuration is now saved to the KE and
5489 connection auth protocol contexts and not fetched anymore in
5490 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
5492 * The local hosts listenning address and port is also resolved
5493 now when starting the server. We want to have the socket object
5494 to include the real address and port for the listener. Added
5495 new function silc_net_check_local_by_sock into the files
5496 lib/silcutil/silcnet.[ch].
5498 * Fixed a broadcast bug in server -> do not broadcast if we
5501 * Fixed a routing bug. Do not route broadcast packets ever.
5502 Broadcast packets must be processed always and not routed since
5503 they may be destined to some other host than yourself and thus
5504 would get routed without no good reason. Affected file is
5507 * Added function silc_server_config_is_primary_route to check
5508 whether primary router connection has been configured (a router
5509 configuration that we are initiating). If there is not, we
5510 will assume that there is only two routers in the SILC network
5511 and we will use the incoming router connection as our primary
5512 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
5514 * Changed the order of the broadcasting. Broadcast _after_ the
5515 packet has been processed not before. Affected file is
5518 * Fixed a [ClientConnection] parsing bug. The port was never
5519 parsed correctly thus resulting to port 0. Affected file
5520 silcd/serverconfig.c.
5522 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
5523 argument and did not set the broadcast packet flag. Affected
5524 file silcd/packet_send.c. Fixed same bug in the function
5525 silc_server_send_notify as well.
5527 * If we receive NEW_ID packet for our own ID in the server, ignore
5530 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5534 * Removed the nickname from the Private Message Payload.
5535 Updated the code and the protocol specs.
5537 * Updated protocol specs for submitting to the IETF.
5539 * Tweaked the Random Number Generator a bit. Affected file
5540 lib/silccrypt/silcrng.c. Exported a new function
5541 silc_rng_[global]_add_noise which can be used to add more
5544 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5546 * Do not parse packets with different timeout when protocol
5547 is active -> may cause problem with rekey. Affected file
5550 * When server receives signoff notify it must not create
5551 new channel key if the client is on any channels since the
5552 sender of the signoff notify will create it.
5554 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5556 * Added printing of error messages during SKE protocol from the
5557 failure packet sent by server during SKE. Affected file
5560 * Removed the client's failure_callback handling with timeout
5561 and handle it immediately when received.
5563 * The SKE library returned wrong type in SUCCESS and FAILURE
5564 packets. They must be 32 bit MSB not 16 bit MSB.
5566 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5568 * Ok, rewrote the logic of the re-key and now it seems to work.
5569 I tested it on high traffic with frequent re-keys without
5570 problems. Added hmac_receive (and renamed hmac to hmac_send)
5571 in SilcClientConnection in lib/silcclient/client.h and
5572 in SilcIDListData in silcd/idlist.h. Also, removed the
5573 SilcPacketParserContext's cipher and hmac fields as they are
5574 not needed anymore and actually caused some problems when
5575 the ciphers and hmac's changed underneath the packet parser.
5577 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5579 * If re-key protocol is active then process the incoming packets
5580 synchronously since we must assure that icoming packets encrypted
5581 with the old key is processed before the new keys is set to
5582 use. This is true other packets than for REKEY packets.
5583 Affected file silcd/server.c. The same was done to client library
5584 as well, affected file lib/silcclient/client.c.
5586 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5588 * Fixed bug in client and server to accept the force send if
5589 the packet is send from silc_[server/client]_packet_process
5590 function. Otherwise the packets are never delivered, oops.
5592 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5594 * Disable force sending of packets when REKEY protocol is active.
5595 We must assure that no packet is sent directly when rekey is
5596 performed. All packets must be sent through packet queue.
5597 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
5598 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
5599 function is silc_[server/client]_packet_send_real to check
5602 * Replaced the SIM paths from example config files to
5603 /usr/local/modules. Also, make install creates now
5604 /usr/local/silc/logs directory to hold all the SILC server
5607 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5609 * Made the configure.in.pre work on Solaris. Patch by salo.

5612 CBC mode macros into lib/silccrypt/ciphers_def.h.
5614 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5616 * Fixed the make install.
5618 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5620 * When MAC computation fails the silc_packet_decrypt returned 0
5621 even though it was supposed to return -1. Fixed this. The
5622 affected file is lib/silccore/silcpacket.c.
5624 * Do not replace the config files in /etc/silc (in make install)
5625 if they already exist. Affected file ./Makefile.am.
5627 * Do not send re-key packets immediately but through packet queue.
5628 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
5630 * Changed silc_net_check_host_by_sock to return FALSE if the
5631 IP/DNS could not be resolved. Though, it returns the IP address
5632 now even if it could not resolve it (but returns also FALSE).
5633 Affected file lib/silcutil/silcnet.[ch].
5635 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5637 * Added silc_pkcs_decode_identifier to decode the public key's
5638 identifier. Affected file lib/silccrypt/silpkcs.[ch].
5639 Added also silc_pkcs_free_identifier. Added also new context
5640 SilcPublicKeyIdentifier.
5642 * Added -S option to the silc client. It is used to dump the
5643 contents of the specified public key file.
5645 * Changed the PKCS api to return the public key length when
5646 setting the public key.
5648 * Fixed a fatal bug in the public and private key file loading.
5649 Affected file lib/silccrypt/silcpkcs.c.
5651 * Execute the packet parsing for client with zero (0) timeout
5652 if the protocol is active. Affected file silcd/server.c.
5654 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5656 * Made the key generation options to the silcd program. Added
5657 -C option, equivalent to client's option.
5659 * Added new [ServerKeys] config section to the server. It
5660 configures the server's public and private key.
5662 * Defined generic Public Key Payload into the protocol
5663 specification to send specific type of public keys and
5666 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
5667 public key or certificate.
5669 * Implemented the GETKEY command to the server and to the
5670 client library and on user interface.
5672 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5674 * Made preliminary `make install' work.

5703 SilcClientConnection structure; not needed. Affected file is
5704 lib/silcclient/client.h.
5708 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5710 * Do not ask whether user wants to use the negotiated private key
5711 for private messages, just use it. Affected file is
5712 silc/local_command.c.
5714 * Added `send_enc_key' and `enc_key_len' fields to the
5715 SilcIDListData structure since they are needed in the re-key

5739 * Changed _ALL_ unsigned long and unsigned int to uint32,
5740 unsgined short to uint16 in the source tree.
5742 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
5743 not handle clients that has entry->data.registered == FALSE.
5744 They are not in the network anymore. Affected file is
5747 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

5760 library. Affected file lib/silcclient/client_notify.c. Also,
5761 implemnted the printing of the SERVER_SIGNOFF info to the
5762 application. Affected file silc/client_ops.c.
5764 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
5765 if the deleting was successful. Affected file silcd/idlist.[ch].
5767 * Added support for public key authentication in the connection
5768 authentication protocol in the client library. Affected file
5769 lib/silcclient/protocol.c.
5771 * Changed the server's silc_idlist_get_clients_by_* interface
5772 to support already allocated array so that new entries may be
5773 added to pre-allocated array. Affected file silcd/idlist.[ch].
5774 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
5775 and command replies.
5777 * All command reply functions in the server now calls the
5778 pending command callback even if error occured. This way the
5779 error will be delivered to the client as well. Affected files
5780 silcd/command.c and silcd/command_reply.c.
5782 * Fixed INFO command to return local server's info if no server
5783 was provided. Affected file lib/silcclient/command.c.
5785 * Removed RESTART command for good. Updated the code and the
5788 * Rewrote parts of the task system. It is a bit simpler now.
5789 Removed unsued task priorities. The affected files are
5790 lib/silcutil/silctask.[ch].
5792 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5794 * Moved the USERS printing from the library to the application.
5795 Affected files lib/silcclient/command.c and silc/client_ops.c.
5797 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5801 * Added channel key re-key support. The re-key is perfomed
5802 only by the router and is done once in an hour. Added `rekey'
5803 field to the SilcChannelEntry in the server. Affected files
5804 silcd/server.c and silcd/idlist.h.
5806 * Added silc_task_unregister_by_context into the file
5807 lib/silcutil/silctask.[ch].
5809 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5811 * Added SILC_UMODE_GONE mode to indicate when the client is not
5812 present in the SILC network. Added also support to the local
5813 command AWAY that will set this mode. Added support of showing
5814 "xxx is gone" in WHOIS command. The USERS command shows the
5815 gone status as well.
5817 * Fixed setting server and router operator privileges in the
5818 server's UMODE command. Affected file silcd/command.c.
5820 * Merged the SKE KE1 and KE2 payloads into one payload. The
5821 new KE payload is equivalent to the old KE2 payload.
5823 Cleaned up the SKE Start Payload parsing. It now uses the
5824 simple buffer unformatting to do the parsing. A lot faster
5827 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
5828 to the SKE that is used to indicate whether both of the SKE
5829 parties should perform authentication. By default only the
5830 responder performs authentication. By setting this flag also
5831 the initiator must do authentication. By default it is unset
5832 since in normal SKE case, client to server connection, only
5833 the responder should do authentication. When doing SKE between
5834 two clients both should perform authentication. Updated the
5835 code and the protocol specs.
5837 * A little fix to IDENTIFY command in the server. Search the
5838 client first by hash not nickname. Affected file is
5841 * Fixed the silc_client_close_connection to support closing
5842 the client to client connections wihtout deleting too much
5843 data. Affected file lib/silcclient/client.c.
5845 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
5846 are received if protocol used to be active but is not anymore
5847 the application would crash due to NULL pointer dereference.
5848 Affected files silcd/server.c and lib/silcclient/client.c.
5850 * Added `hash' field to the SilcClientConnection to include
5851 the hash function negotiated in the SKE protocol.
5853 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
5854 to set the channel founder authentication data. A client can
5855 claim the founder rights later by providing the authentication
5856 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
5857 This way the channel founder can regain the channel founder
5858 privileges even it is left the channel. This works only on
5859 local server and the client must be connected to the same
5860 server to be able to regain the founder rights. Updated the
5861 protocol specs accordingly.
5863 Added support to the CMODE command in the client to set the
5864 founder auth data. Read the README to see how to set it.
5866 Added support to the CUMODE command to claim the founder
5867 rights. Read the README to see how to do it.
5869 Added support for the founder authentication to the Channel
5870 Entry in the server. Affected file silcd/idlist.h.
5872 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
5873 server's CMODE command. Affected file silcd/command.c.
5875 * Added the following new functions into lib/silccore/silcauth.[ch]:
5876 silc_auth_get_method and silc_auth_get_data.
5878 * The server now saves the remote hosts public key to the
5879 SilcIDListData pointer. Affected file silcd/protocol.c.
5881 * The normal server now does not remove the channel entry from
5882 the cache if the founder authentication data is set. It used
5883 to remove it if the founder was the last one on the channel on
5884 the server and left the channel. The auth data is saved and
5885 if the channel is re-joined later the old entry is used with
5886 the old auth data. Affected files silcd/command_reply.c and
5889 * Removed the `pkcs' field from the SilcIDListData structure
5890 in the server; it is not used. Affected file silcd/idlist.h.
5892 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5894 * Fixed packet processing on slow links. Partial packets were
5895 never re-processed because the incoming data buffer was cleared
5896 by the application. Application must not directly clear the
5897 sock->inbuf, the packet processing routines handle it. Fixed
5898 this in client library and in server.
5900 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5902 * Fixed the WHOIS and IDENTIFY send reply function to really
5903 check whether to send list or just one entry. Affected file
5906 * Cleaned up the LEAVE command's channel key distribution. The
5907 affected file silcd/command.c.
5909 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
5910 can enforce the channel mode as well. In that case the ID
5911 includes the ID of the server. The code now enforces the
5912 mode change if the router have different mode than the server.
5914 * The notify client operation with CMODE_CHANGE notify can now
5915 return NULL client_entry pointer if the CMODE was not changed
5916 by client. Application must check for this.
5918 * Added <Server ID> argument to INFO command to support server
5919 info fetching by Server ID.
5921 * Added silc_server_announce_get_channel_users to get assembled
5922 packets of channel users of the specified channel. Affected
5923 file silcd/server.[ch].
5925 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
5926 was freed underneath the ID Cache.
5928 * Re-announce clients when the server received CHANNEL_CHANGE
5929 notify from the router. Affected file silcd/packet_send.c.
5931 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5933 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
5934 crashed since it did not handle the fact that there is no cipher
5935 called "3" and didn't check the error condition. Now fixed.
5937 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
5938 flag. It can be used to send message requests.
5940 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5942 * Implemented the RESTART command in the client.
5944 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
5945 notice type messages. Added notice printing to the user
5948 * The channel keys are not re-generated if the channel's mode
5949 is PRIVKEY, ie private key on the channel exists. Affected
5950 files silcd/server.c and silcd/command.c.
5952 * Fixed a little bug in channel message delivery when channel
5953 private keys are set in the server. Affected file is
5954 silcd/packet_send.c.
5956 * Changed the setting on channel->on_channel = TRUE from the
5957 silc_client_save_channel_key to the JOIN command reply. The
5958 key payload is not received if the private channel key is set.
5959 Affected file lib/silcclient/command_reply.c and the
5960 lib/silcclient/client_channel.c.
5962 * When the CMODE_CHANGE notify is sent and the channel private
5963 key mode is removed the channel key must be re-generated in
5964 other cells as well. Added this support for the router in the
5965 silcd/packet_receive.c.
5967 * Added new local command NOTICE to send notice message on
5968 channel. Affected file silc/local_command.[ch].
5970 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5972 * Added new local command ME to the client. It is used to send
5973 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
5974 some action. Affected file silc/local_command.[ch].
5976 * Changed channel_message and private_message client operations
5977 to deliver the message flags to the application. Added also
5978 the `flags' arguments to the silc_client_send_channel_message
5979 and silc_client_send_private_message functions. Affected file
5982 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5984 * Redefined the Private Message Payload to support private message
5985 keys and to support the new private message flags. Updated
5986 the protocol specs. Flags makes it possible to have for example
5987 CTCP style messages.
5989 * Added new type SilcPrivateMessagePayload and defined an API
5990 for it in the lib/silcclient/silcprivate.[ch].
5992 * Tested private message private keys successfully. Tested the
5993 private message key set, unset and list commands with the new
5996 * Redefined the Channel Message Payload to include the channel
5997 message flags (equal with private message flags) to support
5998 for example CTCP style messages.
6000 * Defined some of the message (for channel and private message)
6001 flags. Updated the protocol specs and added the flags to the
6002 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
6004 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6006 * Added SilcKeyAgreementStatus type to the key agreement routines
6007 to indicate the current status and error if one occured.
6008 The status types are defined in the lib/silcclient/silcapi.h.
6010 * Added new local command KEY that is used to set and unset private
6011 keys for channels, set and unset private keys for private messages
6012 with remote clients and to send key agreement requests and
6013 negotiate the key agreement protocol with remote client. The
6014 key agreement is supported only to negotiate private message keys,
6015 it currently cannot be used to negotiate private keys for channels,
6016 as it is not convenient for that purpose.
6018 * Fixed a minor pending callback setting bug in the function
6019 silc_client_get_client_by_id_resolve, now the function works.
6020 Affected file lib/silcclient/idlist.c.
6022 * Added function silc_net_get_local_port to get local bound
6023 port by socket. Added to lib/silcutil/silcnet.[ch].
6025 * Added `sockets' and `sockets_count' fields to the SilcClient
6026 object. They hold the sockets of the listenning sockets in
6027 the client. Listenning sockets may be for example the key
6028 agreement server. Affected file lib/silcclient/client.[ch].
6029 Added functions the silc_client_add_socket and the
6030 silc_client_del_socket. They are exported to the application
6033 * Added ~./silc/clientkeys to support other client's public keys.
6035 * Renamed verify_server_key client operation to verify_public_key
6036 and added one argument to indicate the type of the connection
6037 (server, client etc.).
6039 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6041 * Added silc_server_connection_auth_request to handle the
6042 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
6043 silcd/packet_receive.[ch].
6045 * Added silc_server_send_connection_auth_request into the
6046 silcd/packet_send.c to send the connection auth request packet.
6048 * Cleaned up the silcd/protocol.c a bit and fixed some memory
6051 * Fixed the public key authentication in responder side in the
6052 server. The `auth_data' pointer includes the SilcPublicKey
6053 not the path to the public key. Affected file silcd/protocol.c.
6055 * Implemented the public key authentication in the initiator side
6056 in the server. Affected file silcd/protocol.c.
6058 * Removed the [RedirectClient] config section from the server
6059 configuration. Is not needed and I don't want to implement it.
6061 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6063 * Cleaned up the CMODE command in the server. It now works
6064 correctly and supports all the modes defined in the protocol.
6065 Affected file is silcd/command.c.
6067 * Added `hmac_name' field to the SilcChannelEntry in the server
6068 to hold the default HMAC of the channel. It can be set when
6069 creating the channel (with JOIN command). Affected files
6072 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
6073 type to indicate the change of the current cipher and hmac
6074 on the channel. Client can safely ignore the <cipher> argument
6075 (if it chooses to do so) since the CHANNEL_KEY packet will
6076 force the channel key change anyway. The <hmac> argument is
6077 important since the client is responsible of setting the new
6078 HMAC and the hmac key into use.
6080 * Fixed the CMODE command in the client library as well.
6082 * Tested CMODE command in router environment successfully.
6084 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6086 * Show the version of the remote client (or server) when connecting
6087 to the server. It is logged to the log file. Affected file
6088 is silcd/protocol.c.
6090 * Fixed the KILLED notify handling in the client library. The
6091 client must be removed from all channels when receiving the
6094 Also, do not remove the client entry when giving the KILL
6095 command but when the KILLED notify is received.
6097 * Removed silc_idlist_find_client_by_nickname from the server.
6098 Not needed anymore. Affected files silcd/idlist.[ch].
6100 * Implemented the CHANNEL_CHANGE notify type handling to the
6101 server. Affected file silcd/server.c.
6105 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6107 * Added silc_server_send_notify_invite to send the INVITE
6108 notify between routers.
6110 * Implemented the INVITE command correctly to the server.
6112 * Implemented the INVITE notify type handling in the server.
6114 * Implemented the INVITE command to the client library and on the
6117 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6119 * Added function silc_server_get_client_resolve to find the
6120 client entry by ID from all ID lists and then resolve it
6121 (using WHOIS) if it cannot be found. Affected file is
6124 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6126 * Implemented the BAN command to the client library.
6128 * The JOIN command in the server now checks the invite list
6131 * Changed the silc_command_reply_payload_encode_va and the
6132 silc_command_payload_encode_va to support that if argument is
6133 NULL it ignores and checks the next argument. Affected file
6134 lib/silccore/silccommand.c.
6136 * Added silc_server_send_notify_ban to send the BAN notify
6137 type between routers.
6139 * Chaned the silc_notify_payload_encode to support that if
6140 argument is NULL it ignores and checks the next argument.
6141 Affected file lib/silccore/silcnotify.c.
6143 * Tested ban lists in router environment successfully.
6145 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6147 * Implemented BAN command to the server, in silcd/command.[ch].
6149 * Removed the BAN and INVITE_LIST modes from the CMODE command
6152 * Added function silc_string_match to regex match two strings.
6153 Affected files lib/silcutil/silcutil.[ch].
6155 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6157 * Redefined parts of the SilcChannelEntry in the server to support
6158 the new ban and invite lists.
6160 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6162 * Redefined the INVITE command. The same command can be used to
6163 invite individuals to the channel but also to manage the invite
6164 list of the channel (to add to and remove from the invite list).
6165 Updated the protocol specs.
6167 * Added new command SILC_COMMAND_BAN that can be used to manage
6168 the ban list of the channel. Updated the protocol specs.
6170 * Removed the channel modes: the SILC_CMODE_BAN and the
6171 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
6172 in the CMODE command. The equivalent features are now available
6173 using INVITE and BAN commands. Updated the protocol specs.
6175 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
6176 in the network about change in the current ban list. The notify
6177 type is not used by the client.
6179 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
6180 support the invite lists.
6182 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6184 * Added new function silc_string_regexify that converts string
6185 including wildcard characters into regex string that can
6186 be used by the GNU regex library. Added into the file
6187 lib/silcutil/silcutil.[ch].
6189 Added silc_string_regex_combine to combine to regex strings
6190 into one so that they can be used as one regex string by
6191 the GNU regex library. Added into the file
6192 lib/silcutil/silcutil.[ch].
6194 Added silc_string_regex_match to match two strings. It returns
6195 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
6197 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6199 * Imported GNU regex to the soruce tree into lib/contrib.
6200 Fixed some compiler warning from the regex.c.
6202 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6204 * Fixed MOTD command in the server to work in router environment.
6206 * Fixed the MOTD command in the client library to support
6207 the server argument in the command.
6209 * Added `nickname_len' argument to the silc_idlist_add_client
6210 in the server, as the `nickname' argument may be binary data
6213 * Added silc_idlist_get_channels to return all channels from
6216 * Implemented LIST command to the server. Affected file is
6219 * Implemented the LIST command to the client library and on the
6222 * Added [<user count>] argument to the LIST command reply.
6223 With private channels the user count is not shown.
6225 * Updated TODO and README.
6227 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6229 * The client entry's data.registered must be TRUE even with
6230 global client entry on global client list. The data.registered
6231 is used to check whether the client is anymore in the network,
6232 for example with WHOWAS command so it must be valid.
6234 * Fixed the WHOWAS command in the server. It now actually works
6235 in router environment. Added function into silcd/command_reply.c
6236 silc_server_command_reply_whowas_save.
6238 * Added silc_idlist_purge function to the silcd/idlist.c
6239 to periodically purge the ID Cache.
6241 * Fixed INFO command in the server. It works now in router
6242 environment. Added <server name> argument to the INFO command
6243 reply. Updated the protocol specs.
6245 * Fixed minor bug in silc_idcache_purge to not purge if the
6246 expire value is zero.
6248 * Fixed various bugs in WHOIS and IDENTIFY command handling as
6249 they were buggy because of the WHOWAS information.
6251 * Fixed local command MSG to handle the async resolving of
6252 the remote client properly. It used to fail the first MSG.
6253 Affected file silc/local_command.c.
6255 * Added `data_len' field to SilcIDCache context.
6257 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6259 * Update TODO. Todo in commands in the server.
6261 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6263 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
6264 used by routers as broadcast packet to inform other routers
6265 about the changed user mode.
6267 Implemented the notify handling in the server. Affected file is
6268 silcd/packet_receive.c. Added the function
6269 silc_server_send_notify_umode to the silcd/packet_send.[ch].
6271 * Added new generic Channel Payload and deprecated the New Channel
6272 Payload. The New Channel Payload is now the generic Channel
6275 * Added new argument `mode' to the silc_server_send_new_channel
6276 as it is required in the Channel Payload now.
6278 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
6279 and created a new and real SilChannelPayload to represent the
6280 new generic Channel Payload. Implemented the encode/decode
6281 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
6283 * Added silc_server_get_client_channel_list to return the list
6284 of channels the client has joined for WHOIS command reply.
6285 Affected file silcd/server.[ch].
6287 * Implemented the channel list sending in the WHOIS command reply
6288 in server and in the client.
6290 Implemented the channel list displaying on the user interface
6291 as well. Affected file silc/client_ops.c.
6293 * Added silc_channel_payload_parse_list to parse list of Channel
6294 Payloads. It returns SilcDList list of SilcChannelPayloads.
6295 Client for example can use this function to parse the list of
6296 channels it receives in the WHOIS command reply. The caller
6297 must free the list by calling silc_channel_payload_list_free.
6298 Affected files lib/silccore/silcchannel.[ch].
6300 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6302 * Added one new argument <user mode> to the WHOIS command reply
6303 to return the mode of the user in SILC. Updated the protocol
6306 Implemented it to the server and client.
6308 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6310 * Fixed the mode printing on the user interface on joining.
6311 Affected file silc/client_ops.c.
6313 * Implemented the UMODE command and user modes in general to the
6314 client library and to the user interface.
6316 * Implemented the UMODE command to the server.
6318 * The server now sends UNKNOWN_COMMAND error status if client sends
6319 unknown command. Affected file silcd/command.c.
6321 * All server commands now handle the command identifier the right
6322 way when sending the command reply to the client. The client can
6323 use to identify the command replies with the identifier.
6325 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6327 * Added silc_server_get_client_route to resolve the route to
6328 the client indicated by the client ID. Affected file is
6331 * Added silc_server_relay_packet as general function to relay
6332 packet to arbitrary destination. This deprecates functions
6333 like _send_private_message_key, _relay_notify etc. Affected
6334 file is silcd/packet_send.[ch].
6336 Removed silc_server_send_key_agreement,
6337 silc_server_send_private_message_key and
6338 silc_server_packet_relay_notify functions from the file
6339 silcd/packet_send.[ch].
6343 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
6344 server. Affected file silcd/packet_receive.[ch].
6346 * Implemented the KILL command to the client. Implemented the
6347 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
6348 Affected files lib/silcclient/command[_reply].c and
6349 lib/silcclient/client_notify.c. Implemented the KILL notify
6350 printing in the user inteface.
6352 * Fixed a lot silc_parse_nick memory leaks from the client
6353 library in the file lib/silcclient/command.c.
6355 * Changed the silc_server_send_notify_on_channels's `sender'
6356 argument from SilcSocketConnection to SilcClientEntry to
6357 check the sender as entry and not as connection object and not
6358 to send to the client provided as argument. The affected file
6359 is silcd/packet_send.[ch].
6361 * The notify packets that are destined directly to the client used
6362 to not to be processed by the server. Now changed that and the
6363 server processes all notify packets. After relaying the packet
6364 to the client the notify packet is processed in the server.
6366 * The silc_server_free_client_data now checks whether there is
6367 pending outgoing traffic for the client and purges the data to
6368 the network before removing the client entry.
6370 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6372 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
6373 an client is killed from the SILC Network. Updated the protocol
6376 Added new function silc_server_send_notify_killed to the
6377 silcd/packet_send.[ch].
6379 * Added function silc_server_packet_relay_notify to relay notify
6380 packets that are destined directly to a client. In this case
6381 the server does not process the notify packets but merely relays
6382 it to the client. Affected file silcd/packet_send.[ch].
6384 Added also silc_server_packet_process_relay_notify to check
6385 whereto relay the notify. Affected file is
6386 silcd/packet_receive.[ch].
6388 * Implemented the KILL command to the server.
6392 * Added the backup schema desgined last fall to the protocol
6393 specs for everyone to see. The specification is in the
6394 *-spec-xx.txt draft and the packet type definitions for the
6395 backup routers is in *-pp-xx.txt draft. Thusly, added also
6396 new packet type SILC_PACKET_CELL_ROUTERS.
6398 * A big security problem in the implementation discovered. The
6399 signoff of an client did not cause new channel key generation
6400 which it of course should've done. The channel keys must be
6401 always re-generated when client leaves (or signoffs) the channel.
6402 The silc_server_remove_from_channels funtion now handles
6403 the channel key re-generation.
6405 * Added `sender' argument to the silc_server_send_notify_on_channels
6406 to not to send the client provided as argument. Affected file
6407 silcd/packet_send.[ch].
6409 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6411 * Implemented OPER and SILCOPER commands into the server and
6414 * Added silc_auth_verify and silc_auth_verify_data to verify
6415 the authentication directly from the authentication payload.
6416 It supports verifying both passphrase and public key based
6417 authentication. Affected file lib/silccore/silcauth.[ch].
6419 * Added `hash' field to the SilcIDListData structure. It is the
6420 hash negotiated in the SKE protocol. Affected file is
6423 * Slight redesigning of the SilcAuthPayload handling routines.
6424 Do not send SilcPKCS but SilcPublicKey as argument.
6426 * Implemented the public key authentication support to the
6427 serverconfig. The public key is loaded from the provided path
6428 and saved as authentication data to void * pointer. Thus,
6429 changed the unsigned char *auth_data to void *auth_data;
6431 * Fixed SHUTDOWN command to send the reply before the server
6432 is shutdown. :) Affected file silcd/command.c.
6434 * Fixed fatal bug in CONNECT command. The hostname was invalid
6435 memory and server crashed. Affected file silcd/command.c.
6437 * Fixed fatal bug in CLOSE command. The server_entry became
6438 invalid but was referenced later in the command. Affected file
6441 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6443 * Fixed fatal bug in failure packet handling. Server ignored
6444 the failure and thus crashed when it came.
6448 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6450 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
6451 that the command may be executed only once in (about) 2 seconds.
6452 The old SILC_CF_LAG flag is same but allows command bursts up
6453 to five before limiting.
6455 Added the support for CF_LAG and CF_LAG_STRICT flags to the
6456 server code. Various commands now includes the CF_LAG_STRICT
6457 flag to disallow any kind of miss-use of the command.
6459 * Fixed the silc_buffer_unformat to not to allocate any data
6460 if the length of the data is zero. It used to allocate the
6461 length + 1. Affected file lib/silcutil/silcbuffmt.c.
6463 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6465 * Changed the format of AdminConnection configuration section
6466 in the server. Added username of the admin to the format.
6467 Affected files silcd/serverconfig.[ch].
6469 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
6470 to return admin configuration data by host, username and/or
6473 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6475 * Implemented WHOWAS command to the server. Added the functions:
6477 silc_server_command_whowas_parse,
6478 silc_server_command_whowas_send_reply,
6479 silc_server_command_whowas_from_client and
6480 silc_server_command_whowas_from_server
6482 * Added <Client ID> argument to the WHOWAS command reply. Updated
6483 the protocol specs accordingly.
6485 * Implemented WHOWAS command and command_reply to the client
6488 Implemented the WHOWAS printing on the user interface.
6490 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6492 * Added new argument to the WHOWAS command reply, the real name.
6493 It is an optional argument. Updated the protocol specs.
6495 * Added SilcIDCacheDestructor callback that is registered when
6496 the SilcIDCache is allocated. The callback is called when
6497 an cache entry in the ID Cache expires, or is purged from the
6498 cache. Added into lib/silccore/idcache.[ch].
6500 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
6501 to destruct the client entries when the cache entry expires.
6502 Other ID Cache's in server and in the client library ignores
6505 * If the ID Cache entry's `expire' field is zero then the entry
6506 never expires. Added boolean `expire' argument to the
6507 silc_idcache_add function in the lib/silccore/idcache.[ch].
6508 If it is TRUE the default expiry value is used.
6510 * Added silc_server_free_client_data_timeout that is registered
6511 when client disconnects. By default for 5 minutes we preserve
6512 the client entry for history - for WHOWAS command.
6514 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6516 * Added support to the server to enforce that commands are not
6517 executed more than once in 2 seconds. If server receives
6518 commands from client more frequently, timeout is registered
6519 to process the commands. Affected file silcd/command.c.
6520 Added new function silc_server_command_process_timeout.
6522 * Changed NICK_NOTIFY handling in client library to check that
6523 if the client's nickname was changed, so there is no need to
6524 resolve anything from the server.
6526 * Removed error printing from the WHOIS and IDENTIFY commands.
6527 If error occurs then it is ignored silently in the client library.
6528 The application, however, may map the received error to
6529 human readable error string. The application currently maps
6530 the NO_SUCH_NICKNAME error to string.
6532 * Made the command status message public to the application. Moved
6533 them from lib/silcclient/command_reply.c to
6534 lib/silcclient/command_reply.h. The application can map the
6535 received command status to the string with the
6536 silc_client_command_status_message function.
6538 * Added check to the server to check that client's ID is same
6539 as the Source ID in the packet the client sent. They must
6542 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6544 * Added dist-bzip hook to the Makefile.am to make bzip2
6545 compressed distributions.
6547 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6549 * Server now enforces the maximum length for the nickname and
6550 the channel as protocol specification dictates. 128 bytes for
6551 nickname and 256 bytes for channel name.
6553 * Moved the WHOIS printing to the application. The client libary
6554 does not print out the WHOIS information anymore, the application
6555 must do it. Renamed silc_client_command_reply_whois_print to
6556 the silc_client_command_reply_whois_save.
6558 The client's idle time is also sent to the application now, and
6559 the idle is shown on screen.
6561 * Added silc_client_command_reply_identify_save to save the
6562 received IDENTIFY entries.
6564 * Do not check for channel private keys in message sending and
6565 reception if the channel does not have the PRIVKEY mode set.
6566 Affected file lib/silclient/client_channel.c.
6568 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6570 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
6571 just surfaced after chaning the JOIN procedure.
6573 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6575 * Added silc_client_get_clients_by_list to get client entries
6576 from Client ID list, that is returned for example by JOIN
6577 and USERS command replies. The application should use this
6578 function for example when JOIN command reply is received to
6579 resolve the clients already on the channel (library does not
6580 do that anymore as USERS command reply is not used in the JOIN
6581 procedure anymore). Affected files lib/silcclient/silcapi.h and
6582 lib/silcclient/idlist.c.
6584 * JOIN command reply and USERS command reply returns now SilcBuffer
6585 pointers instead of unsigned char pointers when returning
6586 the client list and mode list.
6588 * Added <Client ID> argument to the JOIN command reply, mainly
6589 for the server to identify for which client the command was
6590 originally sent. Updated protocol specs accordingly.
6592 * Added SilcDlist private_key pointer to the SilcChannelEntry
6593 in the client to support the channel private keys. Affected
6594 file is lib/silcclient/idlist.h.
6596 * Added SilcChannelPrivateKey argument to the function
6597 silc_client_send_channel_message so that application can choose
6598 to use specific private ke if it wants to. If it is not provided,
6599 the normal channel key is used, unless private keys are set.
6600 In this case the first (key that was added first) is used
6601 as the encryption key.
6603 * Implemented the support for channel private key handling.
6604 Implemented the following functions:
6606 silc_client_add_channel_private_key,
6607 silc_client_del_channel_private_keys,
6608 silc_client_del_channel_private_key,
6609 silc_client_list_channel_private_keys and
6610 silc_client_free_channel_private_keys
6612 Affected file lib/silcclient/client_channel.c.
6614 * Added the support for the private keys in the channel message
6615 sending and encryption and in the message reception and
6616 decryption. Affected funtions are
6617 silc_client_send_channel_message and silc_client_channel_message.
6619 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6621 * Added SKE's key verify callback to the client library's
6622 KE protocol context. Affected files lib/silcclient/protocol.[ch].
6624 * Removed the statement that server (or router) must send USERS
6625 command reply when joining to the channel so that the client
6626 knows who are on the channel. Instead, the client list and
6627 client's mode list is now sent in the JOIN command reply to the
6628 client who joined channel. This is better solution.
6630 * Added function silc_server_get_users_on_channel and function
6631 silc_server_save_users_on_channel to the silcd/server.[ch].
6633 * Removed function silc_server_command_send_users from the
6636 * Do not show topic on the client library anymore. The topic is
6637 sent in the command reply notify to the application and the
6638 application must show the topic now.
6640 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6642 * Added client searching by nickname hash into the IDENTIFY and
6643 WHOIS commands in the server as they were clearly missing from
6644 them. Affected file is silcd/command.c.
6646 * Fixed a bug in private message receiving in the client library.
6647 The remote ID was freed and it wasn't supposed, now it is
6650 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6652 * Minor fix to the channel payload; allocate the data area, as it
6653 needs to be of specific length.
6655 * If the key agreement port is zero then the operating
6656 system will define the bound port. Affected files are
6657 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
6659 * Added new function silc_channel_payload_decrypt into the file
6660 lib/silccore/silcchannel.[ch].
6662 * Moved the channel message etc, check from silc_packet_decrypt
6663 to applications. The library calls now a generic
6664 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
6665 when the packet is either normal or special. This was done to
6666 allow more wide range of checking that was not allowed when
6667 the code was in library. Now applications can do virtually any
6668 checks to the packet and return to the library the decision how
6669 the packet should be processed. Affected files are
6670 lib/silccore/silcpacket.[ch].
6672 Added silc_server_packet_decrypt_check to the server and
6673 silc_client_packet_decrypt_check to the client library.
6675 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
6676 to send with specified source and destination information.
6678 * Channel message delivery between routers was broken after the
6679 channel key distribution was fixed earlier. The channel key
6680 was used be to distributed to other routers as well which is not
6681 allowed by the protocol. Now this is fixed and channel keys
6682 really are cell specific and the channel message delivery between
6683 routers comply with the protocol specification.
6685 * Fixed various commands in server to check also the global list
6686 for the channel entry and not just the local list. The affected
6687 file silcd/command.c.
6689 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6691 * Added assert()s to buffer formatting and unformatting routines
6692 to assert (if --enable-debug) when error occurs. Affected
6693 file: lib/silcutil/silcbuffmt.c.
6695 * Changed to auto-reconnect to check whether the remote host is
6696 router and register the re-connect timeout if it is. It used
6697 to check that whether we are normal server, but router must do
6698 auto-reconnect with another router as well. Affected file
6701 * Removed the [<key len>] option from CMODE command as the cipher
6702 name decides the key length, nowadays. See the defined ciphers
6703 from the protocol specification.
6705 * Added [<hmac>] option to the CMODE command to define the HMAC
6706 for the channel. Added SILC_CMODE_HMAC channel mode.
6708 * Added [<hmac>] option for the JOIN command so that user can
6709 select which HMAC is used to compute the MACs of the channel
6712 * Added Hmac field to the Channel Message Payload. The integrity
6713 of plaintext channel messages are now protected by computing
6714 MAC of the message and attaching the MAC to the payload. The
6715 MAC is encrypted. Now, it is clear that this causes some
6716 overhead to the size of the packet but rationale for this is that
6717 now the receiver can verify whether the channel message decrypted
6718 correctly and also when private keys are set for the channel the
6719 receiver can decrypt the packet with several keys and check from
6720 the MAC which key decrypted the message correctly.
6722 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
6723 lib/silccrypt/silccipher.[ch].
6725 * Added silc_hash_len to return the digest length into the
6726 lib/silcrypt/silchash.[ch].
6728 * Rewrote parts of Silc Channel Payload interface in the
6729 lib/silccore/silcchannel.[ch]. The encode function now also
6730 encrypts the packet and parse function decrypts it.
6732 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6734 * Fixed a minor formatting bug in the SKE's key material processing.
6735 It actually might have processed the keys wrong way resulting
6738 * Redefined the mandatory HMAC algorithms and added new algorithms.
6739 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
6740 and hmac-md5 truncated to 96 bits. The mandatory is now
6741 hmac-sha1-96. Rest are optional (including the one that used
6742 to be mandatory). Rationale for this is that the truncated HMAC
6743 length is sufficient from security point of view and can actually
6744 make the attack against the HMAC harder. Also, the truncated
6745 HMAC causes less overhead to the packets. See the RFC2104 for
6748 * Added new [hmac] configuration section. The SKE used to use
6749 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
6750 is of course wrong. The official names that must be proposed in
6751 the SKE are the ones defined in the protocol specification
6752 (hmac-sha1-96 for example). The user can configure any hmac
6753 using any hash function configured in the [hash] section. At
6754 least, the mandatory must be configured.
6756 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
6758 * Added HMAC list to the SKE proposal list. It has now both
6759 hash algorithm list and HMAC list. This makes the protocol
6760 incompatible with previous versions. The SKE now seems to work
6761 the way it is supposed to work, for the first time actually.
6763 * Defined plain Hash algorithms to the protocol specification.
6766 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6768 * Implemented support for key agreement packets into the server.
6769 Added functions silc_server_key_agreement and
6770 silc_server_send_key_agreement. Other than these functions,
6771 server has nothing to do with this packet.
6773 * Added support for private message key packets into the server.
6774 Added functions silc_server_private_message_key and
6775 silc_server_send_private_message_key.
6779 * Changed the silc_[client|server]_protocol_ke_set_keys to be
6780 called in the protocol's final callback instead in the END
6781 protocol state. This makes a little more sense and in the same
6782 time in client we can use the same protocol routines for normal
6783 key exchange and to key agreement packet handling as well.
6785 * Added to both client's and server's KE protocol context the
6786 SilcSKEKeyMaterial pointer to save the key material. We will
6787 bring the key material to the protocol's final callback by doing
6788 this. The final callback must free the key material.
6790 * Added SKE's packet_send callback into client's KE protocol
6791 context so that the caller can choose what packet sending function
6792 is used. This way we can use different packet sending when
6793 doing normal SKE when doing key agreement packet handling (in
6794 the key agreement packet handling we do not want to encrypt
6797 * Implemented the responder side of the key agreement routines
6798 in the client. The client can now bind to specified port and
6799 accept incoming key negotiation. The key material is passed
6800 to the application after the protocol is over.
6802 * Implemented the processing of incoming Key Agreement packet
6803 in the client. Added function silc_client_key_agreement to
6806 * Implemented the intiator side of the key agreement routines
6807 in the client. The client can now initiate key agreement with
6808 another remote client. The key material is passed to the
6809 application after the protocol is over.
6811 * Created client_keyagr.c to include all the key agreement
6814 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
6815 SILC_TASK_CALLBACK except that it is not static.
6817 * Created client_notify.c and moved the Notify packet handling
6818 from the client.[ch] into that file.
6820 * Created client_prvmsg.c and moved all private message and
6821 private message key routines from the client.[ch] into that file.
6823 * Create client_channel.c and moved all channel message and
6824 channel private key routines from the client.[ch] into that file.
6826 * Changed silc_client_get_client_by_id_resolve to resolve with
6827 WHOIS command instead of IDENTIFY command, in the file
6828 lib/silclient/idlist.c.
6830 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6832 * Implemented the SKE's responder side to the Client library.
6834 * When FAILURE is received to the protocol do not trust it
6835 blindly. Register a timeout to wait whether the remote closes
6836 the connection as it should do it, only after that process the
6837 actual failure. This was changed to both client and server.
6839 * Added client_internal.h to include some of the structures
6840 there instead of client.h in lib/silcclient/.
6842 * Added function silc_task_unregister_by_callback to unregister
6843 timeouts by the callback function.
6845 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6847 * Some "Incomplete WHOIS info" errors has been appearing on the
6848 log files. Took away the entry->userinfo check from WHOIS
6849 reply sending. The entry->userinfo is now " " if client did not
6850 provide one. I thought this was fixed earlier but something
6851 is wrong still. Let's see if the error still appears.
6853 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6855 * Fixed a minor bug in the login when the channel key is
6856 re-generated in the server. It used to generate the key in
6857 wrong order and thus caused problems in the channel traffic.
6859 * Fixed a minor bug in channel key distsribution after
6860 KICK command. The key was not sent to the router even though
6863 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6865 * Added silc_ske_process_key_material_data as generic routine
6866 to process any key material as the SILC protocol dictates. The
6867 function is used by the actual SKE library but can be used by
6868 applications as well. This relates to the private message keys
6869 and the channel private keys since they must be processed the
6870 same way the normal SILC session keys. The protocol dictates
6871 this. Affected files: lib/silcske/silcske.[ch].
6873 Added also silc_ske_free_key_material to free the
6874 SilcSKEKeyMaterial structure.
6876 * Defined silc_cipher_set_key function to set the key for
6877 cipher without using the object's method function. The affected
6878 files: lib/silccrypt/silccipher.[ch].
6880 * Implemented silc silc_client_add_private_message_key,
6881 silc_client_add_private_message_key_ske,
6882 silc_client_del_private_message_key,
6883 silc_client_list_private_message_keys and
6884 silc_client_free_private_message_keys functions in the
6887 Added functions silc_client_send_private_message_key to send
6888 the Private Message Key payload and silc_client_private_message_key
6889 to handle incoming Private Message Key payload.
6891 * Added Cipher field to the Private Message Key payload to set
6892 the cipher to be used. If ignored, the default cipher defined
6893 in the SILC protocol (aes-256-cbc) is used.
6895 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6897 * Removed lib/silcclient/ops.h file.
6899 Redefined parts of the SILC Client Library API. Created new
6900 file silcapi.h that deprecates the ops.h file and defines the
6901 published Client Library API. Defined also private message key
6902 API and channel private key API into the file.
6904 This is the file that the application must include from the
6905 SILC Client Library. Other files need not be included by
6906 the application anymore.
6908 * Added new key_agreement client operation callback and also
6909 defined the Key Agreement library API for the application.
6911 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6913 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
6914 is used by clients to request key negotiation between another
6915 client in the SILC network. If the negotiation is started it
6916 is performed using the SKE protocol. The result of the
6917 negotiation, the secret key material, can be used for example
6918 as private message key.
6920 Implemented the Key Agreement payload into the files
6921 lib/silccore/silauth.[ch].
6923 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6925 * Redefined ciphers for the SILC protocol. Added some new ciphers
6926 and defined the key lengths for the algorithms. Changed the
6927 code accordingly. The default key length is now 256 bits.
6929 * Fixed SKE key distribution function silc_ske_process_key_material
6930 when the key length is more than 128 bits. The default key
6931 length in SILC is now 256 bits.
6933 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
6934 to indicate unsupported algorithm.
6936 * Renamed rijndael.c to aes.c and all functions as well.
6938 * Fixed a long standing channel key setting bug in client library.
6939 Weird that it has never surfaced before.
6941 * Fixed bug in channel deletion. If the entire channel is removed
6942 then it must also delete the references of the channel entry
6943 from the client's channel list as the client's channel entry and
6944 the channel's client entry share same memory.
6946 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6948 * Implemented CONNECT and SHUTDOWN commands in the client.
6950 * Implemented CLOSE command to the client.
6952 * Added the function silc_idlist_find_server_by_name into the
6953 files silcd/idlist.[ch].
6955 Added the function silc_idlist_find_server_by_conn into the
6956 files silcd/idlist.[ch].
6958 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6960 * DIE command was renamed to SHUTDOWN. Updated the both code
6963 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
6964 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
6966 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
6969 * Added function silc_server_create_connection function to create
6970 connection to remote router. My server implementation actually
6971 does not allow router to connect to normal server (it expects
6972 that normal server always initiates the connection to the router)
6973 so the CONNECT command is only good for connecting to another
6976 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6978 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
6979 or some other client was kicked from the channel.
6981 Implemented the handling of the notify type to both client
6984 Implemented silc_server_send_notify_kicked to send the KICKED
6985 notify. It is used to send it to the server's primary router.
6987 * Implemented the KICK command into server and client.
6989 * Added `query' argument to the silc_idlist_get_client function
6990 to indicate whether to query the client from server or not if
6993 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
6994 to indicate that the client is not channel founder.
6998 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7000 * Removed the rng context from SilcPacketContext structure and
7001 changed that the packet routine uses the Global RNG API.
7003 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7005 * Added support for quit message that client can "leave" on the
7006 channel when it quits the SILC. It is ditributed inside the
7007 SILC_NOTIFY_TYPE_SIGNOFF notify type.
7009 Added silc_server_free_client_data that will take the
7010 signoff message as argument.
7012 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
7014 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7016 * Updated parts of the protocol specification to keep it up
7019 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7021 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
7022 payloads in one packet.
7024 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
7025 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
7026 use now the new List flag.
7028 * Also deprecated the following packet types: REPLACE_ID,
7029 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
7031 * Added list support for Notify packet in server.
7033 * Added silc_server_send_notify_channel_change to send the
7034 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
7035 the silc_server_send_replace_id.
7037 * Added silc_server_send_notify_nick_change to send the
7038 NICK_CHANGE notify type. Deprecates the function
7039 silc_server_send_replace_id.
7041 * Added silc_server_send_notify_join to send the JOIN notify type.
7042 Deprecates the function silc_server_send_new_channel_user.
7044 * Added silc_server_send_notify_leave to send LEAVE notify type.
7045 Deprecates the function silc_server_send_remove_channel_user.
7047 * Added silc_server_send_notify_cmode and
7048 silc_server_send_notify_cumode to send CMODE and CUMODE notify
7049 types. Deprecates the silc_server_send_set_mode function.
7051 * Added SERVER_SIGNOFF notify type to indicate that server has
7052 quit. This means that all clients on the channel from that
7053 server will drop. This can be also used when netsplit happens.
7055 Deprecated REMOVE_ID packet type since it is not needed anymore
7058 Added silc_server_send_notify_server_signoff to send the
7059 SERVER_SIGNOFF notify type. Deprecates the function
7060 silc_server_send_remove_id.
7062 Added also silc_server_send_notify_signoff to send the
7063 SIGNOFF notify type.
7065 * Employed the PKCS #1. It is the mandatory way to do RSA in the
7066 SILC protocol from this day on. Changed the protocol
7067 specification as well.
7069 * Added silc_server_send_notify_topic_set to send TOPIC_SET
7070 notify type. It is used between routers to notify about
7071 topic changes on a channel.
7073 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
7076 * Partly updated the protocol specification to comply with the
7077 changes now made. It is still though a bit outdated.
7079 * The JOIN notify type now takes one extra argument <Channel ID>.
7080 The packet used to be destined to the channel but now the
7081 JOIN type may be sent as list thus it is impossible to
7082 destine it to any specific channel. By adding this argument
7083 it is again possible.
7085 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7087 * Added CREDITS file. The CHANGES and CREDITS file will appear
7088 in the distribution as well.
7090 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7092 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
7093 types in the server's silcd/packet_receive.c.
7095 * Implemented CMODE and CUMODE to work in router environment.
7097 * Fixed minor encoding and decoding buglet from the
7098 lib/silccore/silcmode.c.
7100 * Fixed buffer overflow from lib/silcclient/command.c in USERS
7103 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
7105 * Changed all SilcConfigServer* and silc_config_server* to
7106 SilcServerConfig* and silc_server_config*, respectively.
7109 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7111 * Associated the ID (client or server ID) to the Authentication
7112 Payload to avoid any possibility of forging. Updated the
7113 protocol specification and the code accordingly.
7115 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7117 * The RSA key length is now save to the RsaKey context in the
7118 key generation process in lib/silccrypt/rsa.c. The key length
7119 is now used to figure out the maximum size of the block allowed
7120 to be encrypted/signed.
7122 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
7123 is equivalent to the silc_mp_mp2bin but does not allocate any
7126 * Changed silc_mp_mp2bin API to take length argument. If it is
7127 non-zero then the buffer is allocated that large. If zero, then
7128 the size is approximated using silc_mp_sizeinbase, which however
7131 * Created Global RNG API which is global RNG that application can
7132 initialize. After initializing, any routine anywhere in the
7133 code (including library) can use RNG without allocating a new
7134 RNG object. This was done to allow this sort of use of the
7135 RNG in code that has no chance to allocate RNG object. All
7136 applications currently allocate this and many routines in the
7137 library use this. Affected file lib/silccrypt/silcrng.[ch].
7139 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
7140 it to use the Global RNG API.
7142 * Defined Authentication Payload into protocol specification that
7143 is used during SILC session to authenticate entities. It is
7144 used for example by client to authenticate itself to the server
7145 to obtain server operator privileges.
7147 Implemented this payload into the lib/silccore/silcauth.[ch].
7148 Implemented also routines for public key based authentication
7149 as the new protocol specification dictates.
7151 Moved definitions of different authentication methods from
7152 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
7154 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
7155 silc_pkcs_verify and silc_pkcs_sign_with_hash and
7156 silc_pkcs_verify_with_hash functions into the file
7157 lib/silccrypt/silcpkcs.[ch].
7159 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7161 * The client entry's userinfo pointer must be always valid.
7162 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
7163 will fail since it requires the userinfo. Now, the userinfo
7164 is allocated as "" if actual userinfo does not exist. Actually,
7165 it must exist and it is totally Ok to drop client connections
7166 that does not announce the userinfo. However, we will make
7167 this workaround for now.
7169 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
7170 to return the remote port by socket.
7172 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7174 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
7175 SILC_SERVER_PENDING_EXEC and added an new macro
7176 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
7177 data or when error occurs while processing the pending command.
7179 Added new argument `destructor' into silc_server_command_pending
7180 and to the SilcServerCommandPending object. This destructor is
7181 now called after calling the pending callback or if error occurs
7182 immediately. If error occurs the actual pending callback won't
7183 be called at all - only the destructor. The destructor may be
7184 NULL if destructor is not needed.
7186 All this applies for client library code as well. Similar
7187 changes were made there as well for the pending commands.
7189 In the client, the application must now allocate the
7190 SilcClientCommandContext with the silc_client_command_alloc
7193 * Added reference counter to the SilcServerCommandContext. Added
7194 function silc_server_command_alloc and silc_server_command_dup
7197 Same type of functions added to the client library for the same
7200 * Removed the cmd_ident from IDListData away since it is now
7201 global for all connections. It is the command identifier used
7202 in command sending and with pending commands. The affected file
7205 * Added reference counter to the SilcSocketConnection objecet to
7206 indicate the usage count of the object. The object won't be
7207 freed untill the reference counter hits zero. Currently only
7208 server uses this, and client ignores it. The client must be
7209 set to use this too later. The affected files are
7210 lib/silccore/silcsockconn.[ch]. Added also the function
7211 silc_socket_dup to increase the reference counter.
7213 This was mainly added because it is possible that the socket
7214 is removed underneath of pending command or other async
7215 operation. Now it won't be free'd and proper DISCONNECTING
7216 flags, etc. can be set to avoid sending data to connection that
7217 is not valid anymore.
7219 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
7220 the connection. After that it sets SILC_SET_DISCONNECTED.
7221 It is, however, possible that the socket data is not still freed.
7222 The silc_server_packet_process now checks that data is not
7223 read or written to connection that is DISCONNECTED. The socket
7224 get's freed when the reference counter hits zero.
7226 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7228 * Changed the client operation API: channel_message operation's
7229 `sender' is now the client entry of the sender, not the nickname
7230 and the `channel' is the channel entry, not the channel name.
7232 In the private_message operation the `sender' is now also the
7233 client entry of the sender not the nickname.
7235 Affected file is lib/silcclient/ops.h and all applications
7236 using the client operations.
7238 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7240 * Moved the calling of ops->connect() from connect_to_server_final
7241 into receive_new_id functin since that is the point when the
7242 client is actually allowed to send traffic to network. The
7243 affected file is lib/silcclient/client.c.
7245 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7247 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
7248 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
7249 (if needs broadcasting) instead of broadcasting the packets one
7250 by one which would make a burst in the network traffic.
7252 * Added `broadcast' argument to the functions in silcd/server.[ch]
7253 silc_server_create_new_channel[_with_id] to indicate whether
7254 to send New Channel packet to primary router.
7256 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7258 * Added new function into the silcd/server.[ch] files:
7259 silc_server_create_new_channel_with_id to create new channel with
7260 already existing Channel ID.
7262 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
7263 lib/silccore/silcpacket.h. This packet is used t send list of
7264 Set Mode payloads inside one packet. Server uses this to set
7265 the modes for the channels and clients on those channels, that it
7266 announced to the router when it connected to it. The protocol
7267 specification has been updated accordingly.
7269 * The silc_server_new_channel did not handle the packet coming
7270 from normal server as it normally does not send that. However,
7271 when it announces its channels it does send it. Implemented
7272 the support for that.
7274 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
7275 into the file lib/silccore/id.h.
7277 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7279 * Fixed memory leaks in the functions silc_idlist_del_client,
7280 silc_idlist_del_channel and silc_idlist_del_server in the file
7281 silcd/idlist.c. All of those leaked like a sieve.
7283 * Fixed some small memory leaks in the client's function
7284 silc_client_notify_by_server.
7286 * Added functions into silcd/server.c: silc_server_announce_clients,
7287 silc_server_announce_channels and silc_server_announce_server.
7288 These functions are used by normal and router server to announce
7289 to its primary router about clients, channels and servers (when
7290 router) that we own. This is done after we've connected to the
7293 These functions effectively implements the following packet types:
7294 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
7295 and SILC_PACKET_NEW_ID_LIST.
7297 * Added new functions into the silcd/packet_receive.[ch]:
7298 silc_server_new_id_list, silc_server_new_channel_list and
7299 silc_server_new_channel_user_list to handle the incoming
7300 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
7302 * Added support of changing Channel ID in the function
7303 silc_server_replace_id. If the server that announces a channel
7304 to the router already exists in the router (with same name but
7305 with different Channel ID), router is responsible to send
7306 Replace ID packet to the server and force the server to change
7307 the Channel ID to the one router has.
7309 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
7310 client that the Channel ID has been changed by the router. The
7311 normal server sends this to the client. Client must start using
7312 the new Channel ID as the channel's ID.
7314 Implemented handling of this new type into lib/silcclient/client.c
7315 into the function silc_client_notify_by_server.
7317 * Added new function silc_idlist_replace_channel_id into the files
7318 silcd/idlist.[ch] to replace the Channel ID.
7320 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7322 * Call silc_server_command_identify_check always when processing
7323 the IDENTIFY command in silcd/command.c
7325 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7327 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
7328 send keepalive packets. The packet can be sent by clients,
7329 servers and routers.
7331 Added function silc_socket_set_heartbeat into the file
7332 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
7333 If not set, the heartbeat is not performed. The actual
7334 heartbeat is implemented in the low level socket connection
7335 library. However, application is responsible of actually
7338 Added silc_server_send_heartbeat to send the actual heartbeat
7339 packet into silcd/packet_send.[ch]. Server now performs
7340 keepalive with all connections.
7342 * Added silc_task_get_first function into lib/silcutil/silctask.c
7343 to return the timeout task with shortest timeout. There was a bug
7344 in task unregistration that caused problems. TODO has been
7345 updated to include that task system must be rewritten.
7347 * The client library will now resolve the client information when
7348 receiving JOIN notify from server for client that we know but
7349 have incomplete information.
7351 * Rewrote parts of silc_server_remove_from_channels and
7352 silc_server_remove_from_one_channel as they did not remove the
7353 channel in some circumstances even though they should've.
7355 * Encryption problem encountered in server:
7357 The LEAVE command used to send the Channel Key packet to the
7358 router immediately after generating it. However, the code
7359 had earlier sent Remove Channel user packet but not immediately,
7360 ie. it was put to queue. The order of packets in the router
7361 was that Channel Key packet was first and Remove Channel User
7362 packet was second, even though they were encrypted in the
7363 reverse order. For this reason, MAC check failed. Now, this
7364 is fixed by not sending the Channel Key packet immediately but
7365 putting it to queue. However, this is more fundamental problem:
7366 packets that are in queue should actually not be encrypted
7367 because packets that are sent immediately gets encrypted
7368 actually with wrong IV (and thus MAC check fails). So, packets
7369 that are in queue should be encrypted when they are sent to
7370 the wire and not when they put to the queue.
7372 However, the problem is that the current system has not been
7373 designed to work that way. Instead, the packet is encrypted
7374 as soon as possible and left to the queue. The queue is then
7375 just purged into wire. There won't be any fixes for this
7376 any time soon. So, the current semantic for packet sending
7379 o If you send packet to remote host and do not force the send
7380 (the packet will be in queue) then all subsequent packets to the
7381 same remote host must also be put to the queue. Only after the
7382 queue has been purged is it safe again to force the packet
7385 o If you send all packets immediately then it safe to send
7386 any of subsequent packets through the queue, however, after
7387 the first packet is put to queue then any subsequent packets
7388 must also be put to the queue.
7390 Follow these rules and everything works fine.
7392 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7394 * Added new function silc_server_remove_clients_by_server to
7395 remove all client entries from ID list when the server connection
7396 is lost. In this case it is also important to invalidate all
7397 client entires as they hold the invalid server entry. This
7398 fixes fatal bug when server has lost connection and will reconnect
7401 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7403 * Made some sanity checks to silc_server_daemonise like to check
7404 whether the requested user and group actually exists.
7406 * Added sanity check to SKE's silc_ske_responder_finish to check
7407 that the public and private key actually is valid.
7409 * Invalidate the client's nickname when receiving Replace ID
7410 packet and the Client ID is being replaced. This means that the
7411 server will query the nickname if someone needs it (client)
7414 * Sort the ID Cache in client library when the ID Cache data
7415 has changed (needs sorting).
7417 * Do not allow for SILC client to create several connections to
7418 several servers. The client does not support windows right now
7419 and generating multiple connections causes weird behaviour.
7421 Irssi-silc client does support windows and can handle several
7422 connections without problems, see: www.irssi.org and SILC plugin.
7424 * Fixed some places where client was added to the IDList. The
7425 rule of thumb is following (in order to get everything right):
7426 If the client is directly connected local client then the
7427 `connection' argument must be set and `router' argument must be
7428 NULL to silc_idlist_add_client function. If the client is not
7429 directly connected client then the `router' argument must
7430 bet set and the `connection' argument must be NULL to the
7431 silc_idlist_add_client function.
7433 * The funtion silc_server_packet_send_local_channel actually did
7434 not check whether the client was locally connected or not. It
7435 does that now. Fixed a bug related to LEAVE command.
7437 * Fixed Remove Channel User payload parsing bug in server's
7438 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
7440 * The server's silc_server_save_channel_key now checks also the
7441 global ID list for the channel as it might not be in the local
7442 list. Fixed a bug related to LEAVE command.
7444 * Is this the end of the [<unknown>] buglet that has been lurking
7445 around for a long time? A little for loop fix in server's
7446 silc_server_command_whois_parse that is used by both IDENTIFY
7447 and WHOIS command. At least, this was a clear bug and a cause
7448 of one type of [<unknown>] buglet.
7450 * WHOIS and IDENTIFY commands call the function
7451 silc_server_command_[whois/identify]_check function even if
7452 we are not router server.
7454 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7456 * Added --with-gmp configuration option. If set the GMP
7457 is always compiled in the SILC source tree. If not set then
7458 it is checked whether the system has the GMP3 installed. If
7459 it has then the GMP won't be compiled (the system's headers
7460 and library is used), if it doesn't have it then the GMP is
7461 compiled in the SILC source tree.
7463 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7465 * Changed RSA private exponent generation to what PKCS #1
7466 suggests. We try to find the smallest possible d by doing
7467 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
7468 not security fix but optimization.
7470 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7472 * Added new config entry [Identity] to fork the server and run
7473 it as specific user and group. A patch from Bostik.
7475 * Imported Dotconf configuration library into lib/dotconf.
7476 This will be used to create the SILC configuration files later.
7477 It will appear in the distsribution after this commit.
7479 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7481 * A big code auditing weekend happening. Auditing code for
7482 obvious mistakes, bugs and errors. Also, removing any code
7485 Removed files for being obsolete:
7487 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
7488 inline in the file lib/silcutil/silcbuffer.h)
7490 o lib/silcutil/silcbufutil.c (the header has inline versions)
7492 Changed code to fix possible error conditions:
7494 o The buffer formatting routines now check that the destination
7495 buffer really has enough space to add the data. This applies for
7496 both buffer formatting and unformatting
7497 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
7498 unformatting was changed to accomodate following rules:
7499 XXX_*STRING_ALLOC will allocate space for the data into the pointer
7500 sent to the function while XXX_*STRING will not allocate or copy
7501 the data into the buffer. Instead it sets the pointer from the
7502 buffer into the pointer sent as argument (XXX_*STRING used to
7503 require that the pointer must be allocated already). This change
7504 makes this whole thing a bit more consistent and more optimized
7505 (note that the data returned in the unformatting with XXX_*STRING
7506 must not be freed now). The routines return now -1 on error.
7508 o Tried to find all code that use buffer_format and buffer_unformat
7509 and added return value checking to prevent formatting and
7510 especially unformatting errors and possible subsequent fatal
7513 o Changed ske->x and ske->KEY to mallocated pointers in
7514 lib/silcske/silcske.h. Fixed possible data and memory leak.
7516 o Added return value checking to all *_parse* functions. Fixed
7517 many memory leaks as well.
7519 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
7520 so that buffer overflows would not happen. All code now also
7521 checks the return value as it can fail.
7523 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7525 * Added reconnection support to server if the normal server looses
7526 its connection to the router (for example if router is rebooted).
7527 The server performs normal reconnection strategy implemented
7528 to the server. Affected file silcd/server.c.
7530 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7532 * Added new packet type SILC_PACKET_SET_MODE that is used to
7533 distribute the information about changed modes (for clients,
7534 channels and clients channel modes) to all routers in the
7535 network. Updated the protocol specification accordingly.
7537 Added functions into silcd/packet_send.c and
7538 silcd/packet_receive.c: silc_server_send_set_mode,
7539 silc_server_set_mode.
7541 Added new files silcmode.[ch] into lib/silccore that implements
7542 the encoding and decoding of Set Mode Payload. Added new type
7543 SilcSetModePayload. Moved the definitions of different modes
7544 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
7546 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7548 * Oops, a little mistake in server's connection authentication
7549 protocol. The protocol is not ended with FAILURE but with
7550 SUCCESS if the authentication is Ok. :) Affected file is
7553 * Implemented NICK_CHANGE notify handling in server in the file
7554 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
7555 the local clients on the channel. After the changing nickname
7556 in router environment snhould work and the [<unknown>] nickname
7557 should appear no more.
7559 The silc_server_replace_id function that receives the Replace ID
7560 payload now sends the NICK_CHANGE notify type also in the file
7561 silcd/packet_receive.c
7563 * Changed WHOIS and IDENTIFY command to support the maximum amount
7564 of arguments defined in protocol specs (3328 arguments). This
7565 fixed a bug that caused problems when there were more than three
7568 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7570 * Added extra parameter, command identifier, to the
7571 silc_client_send_command so that explicit command identifier
7574 Changed that ID list routines uses specific command identifier
7575 when sending WHOIS/IDENTIFY requests to the server so that they
7576 can be identified when the reply comes back.
7578 Affected files lib/silcclient/command.[ch],
7579 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
7581 * Added `sender' argument to silc_server_packet_send_to_channel
7582 to indicaet the sender who originally sent the packet to us
7583 that we are now re-sending. Ignored if NULL. Affected file
7584 silcd/packet_send.[ch].
7586 * Added some server statistics support in silcd/server_internal.h
7587 SilcServerStatistics structure and around the server code. Also
7588 send some nice statistics information when client is connecting
7591 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7593 * Fixed channel ID decoding in server's JOIN command reply in
7594 silcd/command_reply.c
7596 * Fixed braodcasting of replace ID payload to not to send it if
7597 we are standalone server in silcd/packet_receive.c.
7599 * Fixed all channel message sending routines to not to send
7600 packets to clients that has router set, since they are routed
7601 separately in the same function earlier. Affects file
7602 silcd/packet_send.c and all channel packet sending functions.
7604 * In USERS reply, res_argv[i] are not allocated, the table
7605 is allocated. Thus changed that free the table, not its
7608 * In server's whois_check and identify_check if the client is
7609 locally connected do not send any WHOIS commands - they are not
7612 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7614 * Fixed some minor bugs in client when sending WHOIS command. The
7615 arguments was in wrong order.
7617 * Removed statis function add_to_channel from server in
7618 silcd/command.c that was previously used with the joining but
7621 * Tested USERS command in router environment successfully with two
7622 routers, two servers and two clients.
7624 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7626 * Reorganized the USERS command and command reply in client library
7627 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
7628 When the command is given by user we register a pending command
7629 callback that will reprocess the command after the reply has been
7630 received from the server. When reprocessing the packet we then
7631 display the information. Thus, the USERS information is displayed
7632 now in the command callback instead of in the command reply
7633 callback. The processing of the command is same as previously
7634 when server has sent the command reply in the JOINing process.
7636 * Added to USERS command in silcd/command_reply.c to join the client,
7637 we didn't use to know about, to the channel after we've created
7638 a client entry for it. Also, for clienet we did know already still
7639 check whether it is on the channel or not and add it if not.
7641 * Removed silc_server_command_join_notify as the function and its
7644 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7646 * Changed the client's pending command handling to the same as the
7647 server's pending command handling. It is also now possible to
7648 execute command reply functions from other command reply
7649 function as the function callbacks for commands and command
7650 replies are one and same. The pending commands are not static
7651 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
7652 in client connection context. Thus, pending commands are server
7653 connection specific as it is convenient.
7655 Changed the function silc_client_command_pending and
7656 silc_client_command_pending_del and added new function
7657 silc_client_command_pending_check. Removed the
7658 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
7661 * Added cmd_ident, current command identifier, to the client
7662 connection context in lib/silcclient/client.h to keep track on
7663 command identifiers used in command sending. Client's command reply
7664 function handling now supports the mandatory command identifiers.
7666 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
7667 funtions in client to fully support pending command callbacks.
7669 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
7670 as one of the arguments to the application in the command reply
7673 * NOTE: The FORWARDED flag is depracated. It used to be depracated
7674 before first releasing SILC but came back. Now it is removed again
7675 and should come back nomore. The FORWARDED flag was used only
7676 by the JOINing procedure by forwarding the command packet to router.
7677 Now, the JOINing procedure has been changed to more generic (due
7678 to various router environment issues) and FORWARDED is not needed
7679 anymore for anything. The protocol specification is yet to be
7682 Now, removed silc_server_packet_forward from server and the flag
7683 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
7685 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7687 * Renamed NAMES command to USERS command. The NAMES was named that
7688 due to historical reasons. Now it is renamed. Also, rewrote
7689 parts of the USERS command. The nickname list is not sent anymore
7690 by the server. Only Client ID and mode lists are sent in the USERS
7691 command. Changed this also to the protocol specification.
7693 The client now resolves the names and stuff after it receives
7694 the USERS list from the server when joining to the channel.
7696 * WHOIS and IDENTIFY commands has been changed to support multiple
7697 Client ID's per command. One can now search for multiple users
7698 in the network by sending only one WHOIS or IDENTIFY command.
7699 Changed the code and the protocol specifications.
7701 * Removed silc_server_command_identify_parse and changed that IDENTIFY
7702 uses silc_server_command_whois_parse to parse the request. */
7704 * If normal server, do not parse the WHOIS and IDENTIFY requests
7705 before sending it to the router. Saves some time.
7707 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7709 * Fixed JOIN command on client library. Wrong number of arguments
7710 used to crash the client.
7712 * Added silc_server_channel_has_global function to check whether
7713 channel has global users or not.
7715 * Added silc_server_channel_has_local function to check whether channel
7716 has locally connected clients on the channel.
7718 * The silc_server_remove_from_one_channel now checks whether the
7719 channel has global users or not after given client was removed from
7720 the channel. It also checks whether the channel has local clients
7721 on the channel anymore. If it does not have then the channel entry
7722 is removed as it is not needed anymore.
7724 * The silc_server_notify now checks on JOIN notify whether the joining
7725 client is one of locally connected or global. If it is global then
7726 the channel has now global users on the channel and that is marked
7727 to the channel entry. Also, it now saves the global client to
7728 global list who is joining and JOINs it to the channel. This is
7729 for normal server, that is.
7731 Changed silc_server_send_notify_on_channel,
7732 silc_server_packet_relay_to_channel and
7733 silc_server_packet_send_to_channel check if we are normal server
7734 and client has router set (ie. global client) do not send the
7735 message to that client, as it is already routed to our router.
7737 * Implemented LEAVE notify type handling in silc_server_notify
7740 * Tested LEAVE command in router environment successfully. Tested
7741 with two routers, two servers and two clients.
7745 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
7747 * Implemented SIGNOFF notify type handling in silc_server_notify
7750 * silc_server_remove_id now removes the client entry from all channels
7751 it has joined and thusly sends SIGNOFF notify type.
7753 * Rewrote the NAMES list generation in server by removing two excess
7754 loops. The lists are created now inside one loop.
7756 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7758 * silc_server_remove_channel_user checks now also global list
7759 for channel and client.
7761 * silc_server_new_channel_user checks now both local and global
7762 list for channel and client. Fixed a bug in client id decoding.
7763 Used to decode wrong buffer.
7765 * silc_server_channel_message checks now both local and global
7766 list for channel entry.
7768 * Tested channel joining (hence JOIN) in router environment
7769 successfully. Tested with two routers, two servers and two
7772 * Tested channel message sending in router environment successfully.
7774 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7776 * Added silc_server_save_channel_key into server.[ch] to save the
7777 received channel key in Channel Key payload processing. It is
7778 also used in JOIN command reply handling.
7780 Equivalent function silc_client_save_channel_key added into
7781 client.[ch] into client library.
7783 * Changed JOIN command reply to send information whether the channel
7784 was created or not (is existing already) and the channel key
7785 payload. Changed protocol specs accordingly.
7787 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
7788 the request was sent by ID and not by nickname. Crashed on
7791 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7793 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
7794 now correctly save the received data.
7796 * silc_server_free_sock_user_data now notifies routers in the
7797 network about entities leaving the network.
7799 At the same time implemented functions silc_server_remove_id
7800 and silc_server_send_remove_id to receive and send REMOVE_ID
7801 packets. The packet is used to notify routers in the network
7802 about leaving entities. The ID removed will become invalid in
7805 * Added function silc_idlist_del_server into server. Removes and
7806 free's server entry from ID list.
7808 * silc_server_private_message function now checks, if we are router,
7809 that the destination ID really is valid ID, naturally.
7811 * In router when NEW_ID packet is received (for new client) the
7812 hash of the Client ID is saved in the ID Cache but the
7813 client->nickname is set to NULL, instead of putting the hash
7816 IDENTIFY command now also checks that client->nickname must be
7817 valid. If it is not if will request the data from the server who
7818 owns the client. Added new function
7819 silc_server_command_identify_check.
7821 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
7822 to set the command to already allocated Command Payload.
7824 * Tested private message sending in router environment with two
7825 routers, two servers and two clients. Fixed minor bugs and now
7828 * Fixed segfault from client's NAMES command. Used to crash if
7831 * Forwarded packets must not be routed even if it is not destined
7832 to the receiver. Changed server code comply with this.
7834 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7836 * Added `require_reverse_mapping' boolean value to ServerParams
7837 structure. If TRUE (not default) the server will require that
7838 the connecting host has fully qualified domain name.
7840 If the reverse mapping is not required and hostname could not be
7841 found the IP address is used as hostname.
7843 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7845 * Implemented version string checking to both client and server.
7846 The check is incomplete currently due to the abnormal version
7847 strings used in development version of SILC.
7849 * Changed all command functions in server to use the new
7852 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7854 * Changed char *data to unsigned char *data in ID Cache system to
7855 support binary data as ID Cache data. Changed code to support
7856 binary data in lib/silccore/idcache.c.
7858 * Renamed silc_server_packet_relay_command_reply to
7859 silc_server_command_reply as it is normal packet receiving
7860 function. Rewrote the function to accept command replys for
7861 servers and not only for clients.
7863 * Mark remote router always as registered server if we are connecting
7864 to it. Otherwise, commands sent by the router to us are ignored.
7866 * All ID List find routines now returns the ID Cache Entry pointer
7867 as well if requested.
7869 * WHOIS command works now in router environment, tested with two
7870 routers, two servers and two clients.
7872 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
7873 in router environment (as it is almost equivalent to WHOIS) but
7874 hasn't been tested thoroughly. Added new functions:
7876 silc_server_command_identify_parse
7877 silc_server_command_identify_send_reply
7878 silc_server_command_identify_from_client
7879 silc_server_command_identify_from_server
7881 * Disabled route cache adding because adding two different ID's with
7882 same IP replaces the old cache entry thus giving wrong route.
7883 The entry->router->connection is always the fastest route anyway
7884 so route cache may not be needed. Of course, new routes maybe
7885 established after receiving the ID when the entry->router->connection
7886 might not be anymore the most optimal.
7888 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7890 * Add route cache for received ID for fast routing.
7892 * Added silc_server_packet_route to route received packet on router
7893 that is not destined to us.
7895 * Renamed silc_server_get_route to silc_server_route_get.
7897 * Added id_string and id_string_len fields into SilcServer to
7898 include encoded ServerID for fast comparing without excess
7899 encoding of the ID's.
7901 * Cleaned up WHOIS command on server side. Added following static
7904 silc_server_command_whois_parse
7905 silc_server_command_whois_check
7906 silc_server_command_whois_send_reply
7907 silc_server_command_whois_from_client
7908 silc_server_command_whois_from_server
7910 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
7911 arguments in command replies. All command functions should be
7912 updated to use this macro.
7914 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7916 * Minor typo fixes on command reply handling on server.
7918 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7920 * Added silc_server_command_add_to_channel internal routine to add
7921 the client to the channel after router has created the channel and
7922 sent command reply to the server.
7924 * Added generic silc_server_send_command to send any command from
7927 * Use static buffer with ID rendering instead of duplicating data.
7929 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7931 * Fixed a channel user mode bug when joining to a channel server gave
7932 everybody channel founder rights, oops.
7934 * We mark ourselves as the router of the incoming server connection
7935 if we are router ourselves. This way we can check in some packet
7936 sending functions whether it is locally connected server. For
7937 incoming router connections we put NULL.
7939 * For router sending packets locally means now always sending the
7940 packet cell wide; to local clients and local servers. For normal
7941 server sending packet locally means sending it to only local
7944 * Fixed the JOIN command to really work in router environment. If the
7945 channel is created it is always created by the router. Router is
7946 also responsible of making the initial joining to the channel,
7947 sending JOIN notify to the sending server and distributing
7948 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
7949 does not exist server doesn't do anything else but forward the
7950 command to the router which performs everything.
7952 * Added silc_server_send_channel_key function to send the Channel Key
7955 * Added silc_server_create_channel_key to create new channel key. The
7956 channel key is now re-generated everytime someone joins or leaves
7957 a channel, as protocol dictates. Note: channel->key_len is the
7960 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7962 * Splitted server.[ch] finally. Created now packet_send.[ch] and
7963 packet_receive.[ch] to separate packet sending and receiving
7964 routines. The server.[ch] now includes everything else including
7965 actual packet processing (writing and reading data) and other
7968 Renamed silc_server_private_message_send_internal to
7969 silc_server_send_private_message. The routine is still though
7970 used only to relay private messages as server does not send
7971 private messages itself.
7973 Renamed silc_server_new_channel to silc_server_create_new_channel
7974 and added new function sicl_server_new_channel that handles the
7975 incoming New Channel packet. Added also new sending function
7976 silc_server_send_new_channel to send New Channel Payload.
7978 * Added new function silc_server_notify to process incoming notify
7979 packet to the server/router. Server may then relay the notify
7980 to clients if needed.
7982 * Added new function silc_server_new_channel_user to process incoming
7983 New Channel User packet. Router will redistribute the packet and
7984 send JOIN notify to its local clients and locally connected servers
7985 if needed. Normal server will send JOIN notify to its local client
7986 on same channel when received this packet. Added also corresponding
7987 sending function silc_server_send_new_channel_user to sent the
7990 * Added boolean route argument to send_notif_to_channel and
7991 packet_send_to_channel functions to attempt to route the packet
7992 if it is TRUE and send only locally if it is FALSE.
7994 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7996 * silc_server_replace_id now broadcasts the received replace ID
7997 packet if it is not broadcast packet already. The router must
7998 broadcast to inform other routers about changed ID.
8000 * Added backpointer to server's router into SilcServer context in
8001 silcd/server_internal.h.
8003 * Fixed silc_server_packet_broadcast to send correct broadcast
8006 * The channel key is now distributed to the local client as soon
8007 as it is received from the router (in router environment) so that
8008 no other packet may be sent for the channel until client has
8011 * silc_server_remove_channel_user now broadcasts the received
8012 Remove Channel User packet if it is not broadcast packet already.
8013 The router must broadcast to inform other routers about removed
8016 * Added users field into SilcPacketContext that is a reference count
8017 of the context. One can increase the reference count by calling
8018 silc_packet_context_dup which is now changed to just increase the
8019 reference count instead of duplicating the data. The reference
8020 count is decresed by calling silc_packet_context_free that will
8021 free the data after the reference count hits zero.
8023 For now on the packet context and everything allocated into it
8024 (including the raw packet from network) must be freed by calling
8025 the new silc_packet_context_free function. Added also new function
8026 silc_packet_context_alloc that must be used now to allocate the
8027 context. This also means that if a routine is asynchronous from
8028 silc_[client/server]_packet_parse_type the packet context must
8029 be duplicated by calling silc_packet_context_dup. Otherwise it
8030 gets free'd after silc_[client/server]_packet_parse_type returns.
8031 Also, one must remember that if packet is duplicated then its
8032 reference count must be decresed by calling the free function as
8033 many times as it was duplicated.
8035 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
8036 from both client and server.
8038 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8040 * Made joining to a channel working in router environment.
8042 * Cleaned up JOIN command on server side and create function
8043 silc_server_command_join_channel internal routine to make the
8046 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8048 * Changed silc_command_pending list to SilcDList. Also, added
8049 `ident' field to SilcServerCommandPending structure to identify
8050 the reply and to call correct callback.
8052 Added silc_server_command_pending_check function to replace the
8053 corresnponding macro. The silc_command_pending list is not
8056 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
8057 to set identifier to previously allocated Command Payload. It
8058 is used to set identifier for command when resending Command
8061 * Added silc_command_payload_encode_payload to encode Command
8062 Payload buffer from SilcCommandPayload structure.
8064 * Added silc_argument_payload_encode_payload to encode Argument
8065 payload buffer from SilcArgumentPayload structure.
8067 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8069 * Changed WHOIS command to support router connection on server side.
8070 The whois request is always sent to router unless the server is
8071 standalone server. After server has received the reply from the
8072 router will it send the reply to the client.
8074 * Added silc_server_packet_broadcast into silcd/server.[ch] to
8075 broadcast received broadcast packet. The function is used only
8076 by router. The broadcast packet is always sent to the router's
8079 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
8080 render given ID to printable string, for log files for example.
8082 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8084 * Made basic router to router connections working. At least they
8085 can now connect to each other but nothing really works the way
8086 they are supposed - yet.
8088 * Added new initiator token to RouterConnection configuration
8089 file in silcd/serverconfig.[ch]. It is used to tell whether we
8090 are the initiator to the remote router or whether we'll expect
8091 the other end to connect.
8093 * Moved registering of listener task to silc_server_init, hence
8094 the server starts listenning as soon as it is run, even if it
8095 does not have connections to other routers. Let's see how well
8098 * Changed default connection retry timeouts for more suitable in
8101 * Removed cipher and such arguments from silc_idlist_add_client
8102 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
8103 Added new function silc_idlist_add_data to add the keys and stuff
8106 * Added SilcIDListData structure and added it to SilcClientEntry
8107 and SilcServerEntry as their first field in the structure. This
8108 way we can explicitly cast the ID entries to the SilcIDListData
8109 structure and get common data for the entries. In past, we had
8110 to first check what type of connection it is and then cast it to
8111 correct ID entry type. Now, we can directly cast the opaque
8112 pointer to the SilcIDListData (no matter what ID entry it actually
8113 is) and get the data needed.
8115 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8117 * Wow, found a bug in scheduler. The scheduler uninitialized itself
8118 in some circumstances even if threre were timeout tasks, though not
8119 IO tasks, but tasks anyway. Now fixed.
8121 * Defined SilcServerConnection structure to hold connection specific
8122 stuff about directly connected servers and routers. The definition
8123 is currently in silcd/server_internal.h. I thought about having
8124 a bit more important role fro this struct but for now it is used
8125 only when connecting to other server (or router actually).
8127 * Added connecting retry support in server when connecting to
8128 router(s). The retry feature implement exponential backoff
8129 algorithm. Also, added SilcServerParams structure to hold default
8130 parameters for server. For now, it include these retry settings
8131 and are hard coded. After server is moded to be as Silc Server
8132 Library this structure will be more important.
8134 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8136 * Changed client librarys channel->clients table to SilcList and
8137 changed code accordingly.
8139 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8141 * Changed client's channel table to SilcList and changed code
8142 accordingly. Also changed SilcChannelClientEntry to include back-
8143 pointer to the channel so that client entry can use that structure
8144 as list as well and we have fast cross-reference to the channel.
8145 This change dramatically decreased the complexity of channel
8146 handling with client entry and vice versa (removed one extra
8147 loop when searching for channel entry from many functions).
8149 * Changed server->sim from table to SilcDList and changed code
8152 * NAMES command can now be used from user interface. It will show
8153 the user list on the channel, neatly.
8155 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
8156 Code now saves realname of the user if it becomes available.
8158 * Renamed configure.in to configure.in.pre and made ./prepare
8159 script to automatically add correct version string to
8160 configure.in which it creates from configure.in.pre.
8162 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8164 * NAMES command reply now shows users mode with the nickname when
8167 * Moved silc_client_ch[u]mode[_char] functions from
8168 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
8169 place sucks, they are utility functions and should be in some
8172 * Fixed some unsigned int's to unsigned short's. Patch by cras.
8174 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
8177 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8181 * Added TRQ (efficient deque and list library) into lib/trq. This is
8182 a very good list library that is currently used in the SILC. Defined
8183 SilcList API over the library because I didn't like the API very
8184 much. See lib/trq/silclist.h for the API and examples of how to
8185 use the API. Fixed various places in the code to use the new
8186 SilcList API. The SilcList is meant for lists that has a structure
8187 already defined as a list. It is not suitable to add just some
8188 context to the list (in TRQ, the context is the list actually).
8190 So, I defined SilcDList that can be used for the purpose where
8191 predefined list structure does not exit. This can be used as
8192 such list. Now some context just can be added to the SilcDList.
8193 Currently this list is not used in the SILC just yet, though there
8194 are a lot places where this can replace dynamically allocated
8195 tables and I will fix these places, later, to use SilcDList.
8196 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
8197 and use TRQ internally).
8199 Also fixed some annoying warning messages that the original TRQ
8200 code generated. Also minor changes to TRQ's Makefile.in.
8202 * Added support for querying by Client ID to both WHOIS and
8203 IDENTIFY commands into server, as required by the protocol.
8205 * Removed method function pointers from SilcBuffer structure. They
8206 weren't used to anything and just increased the context size for
8207 no good reason. This change also made silc_buffer_alloc and
8208 silc_buffer_free functions inline functions.
8210 * Disabled command flooding detection support until it's fixed so
8211 that it accepts commands in but does not execute them more than once
8214 * Added silc_net_localhost(), to return local hostname, into
8215 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
8216 that must be initialized before calling silc_client_init.
8218 * Added new function: silc_server_send_notify_on_channels to send
8219 notify messages to all channels client has joined. It is assured
8220 that the message is sent only once per client.
8222 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
8223 lib/silcutil/silcutil.[ch] as silc_format function. The new
8224 function is generic and is used by server as well, not only by
8225 the logging routines.
8227 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
8228 the provided version string was not acceptable. Added new function:
8229 silc_ske_check_version into lib/silcske/silcske.h. The function
8230 must be implemented by the application (client or server) and it
8231 does not reside in the SKE library. The function checks the version
8232 string remote end sent.
8234 * Added back pointers (to opaque context and to SilcSocketConnection)
8235 into SilcPacketContext structure into lib/silccore/silcpacket.h.
8237 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
8238 duplicate packet context structure.
8240 * Changed `notify' client operation to send same arguments as client
8241 receives from server except for ID's. ID's are mapped to correct
8242 ID entry and that is returned. Also, if channel entry is not sent
8243 by server but the notify is for channel the channel entry is sent
8244 to application (otherwise application doesn't know that it is for
8245 channel (library gets it from packet's Destination ID)).
8247 * Added silc_client_remove_from_channels into client library to
8248 remove a client from all channels it has joined to. Used when
8249 received SIGNOFF notify from server. Added also new function
8250 silc_client_replace_from_channels to replace old ID entry with
8251 new ID entry on all channels. Used when received NICK_CHANGE
8254 * Fixed ID Cache list handling in silc_idlist_get_client in
8255 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
8256 to get (or query) client by ID.
8258 * Updated TODO list.
8260 * Added connection authentication status message defined by the
8261 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
8262 support for these into the code in client and server side.
8264 * Added generic function silc_client_send_command to send any command
8265 with variable argument list. Application should use this function
8266 to send commands if the command functions provided by the library
8267 does not suite for the application's user interface needs.
8269 * Added new `failure' client operation. Application is notified about
8270 received failure packet if client is executing a protocol. In this
8271 case the protocol's execution has failed.
8273 * Added SKE's end notify to send the SKE_SUCCESS notify message that
8274 is required by the protocol.
8276 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
8277 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
8280 * Added status flag to SilcSKE object to indicate realtime status
8281 of the SKE protocol.
8283 * Application receives now exactly same command reply arguments as
8284 the library receives from server. However, if ID is received the
8285 corresponding ID entry is returned to the application (eg. Client
8286 ID is mapped to correct SilcClientEntry entry and that is returned).
8287 Changed command_reply client operation due to this change.
8289 * Changed all ID's in commands and in command replys as ID Payloads.
8290 Change affected both client and server side codes.
8292 All ID's sent in SILC network (with execption of ID's in SILC
8293 Packet header) are sent in ID Payload to support variable length
8296 * Server now notifies nick changes and notifies all clients on
8297 the channels about the new nickname (about the new Client ID,
8300 * Implemented CMODE command to change channel modes. Supports all
8301 channel modes defined by the protocol specs except ban and invite
8302 lists. (Also, private channel key mode is supported but support for
8303 setting private channel key in client is missing, thus, this mode
8304 has no effect on client side (except that server requires that the
8305 client uses private channel key and normal channel traffic does not
8308 Also, invite mode works per se, but INVITE command does not work
8309 yet correctly, so you can set channel as invite only channel but
8310 inviting clients to the channel does not work (it is yet to be
8311 thought what's the best way to do it).
8313 * Added new command SILC_COMMAND_CUMODE to change user mode on the
8314 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
8315 Implemented CUMODE command to change user's mode on the channel.
8316 Supports all modes defined by the protocol specs.
8318 * Added NAMES command reply to return users modes on the channel.
8320 * Removed unnecessary and slow ciphers from lib/silccrypt.
8322 * Set SO_KEEPALIVE option to connection sockets by default.
8324 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
8326 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
8327 redefined the Notify Payload into protocol specs.
8329 * Added silc_id_payload_parse_id to get ID directly from raw
8332 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8334 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
8335 accept searching by Client ID as well.
8337 * Added support for LEAVE and SIGNOFF notify types in client library.
8339 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
8340 to parse ID Payload from raw data.
8342 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8344 * Added flags parameter into silc_ske_assemble_security_properties
8345 function in lib/silcske/silcske.[ch].
8347 * Changed notify client operation to fit better for notify messages
8348 sent by server. The notify payload received from server is now
8349 passed to the application (after parsing it to SilcNotifyPayload).
8350 It is application's responsibility to retrieve the arguments
8351 from the payload and show the message the way it wants. The message
8352 sent by server is implementation specific.
8354 * Changed public keys to comply with the protocol specification.
8355 Old public keys are not supported anymore and are not compatible.
8357 * Removed nickname from Channel Payload as the latest draft removed
8358 it. The client must resolve the nickname from the NAMES command
8359 reply received when it joined the channel.
8361 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
8363 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8365 * Fixed some errors in protocol specification drafts.
8367 * Created lib/silccore/silcnotify.c to implement Notify Payload
8368 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
8369 generic payloads described by protocol specifications. The file
8370 includes implementations for ID Payload and Argument Payload.
8372 * Changed Command Payload implementation to use the new Argument
8373 Payload. Changed command_xxxx_payload to command_payload_xxxx
8374 to comply with SILC coding conventions.
8376 * Added suppport for Argument Payload handling in Notify Payload
8377 implementation as protocol requires it. Added the new support
8378 into server and client lib as well.
8380 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8382 * Added support for multiple nicknames on same channel. [n] is
8383 added locally to the nickname if there are more than one same
8384 nicknames on the channel.
8386 * Server now sends all nicknames that matched WHOIS request.
8387 Client also shows the list received from server.
8389 * Added TOPIC command to client side. User can now set and show
8390 current topic on channel.
8392 * Added MOTD command to client and server. Also, server sends the
8393 motd when client connects to the server.
8395 * Changed version strings to comply ISO 8601.
8397 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8399 * Fixed protocol error handling in client library. It should now
8400 cope even if the SKE fails for some reason.
8402 * Made new protocol specification drafts for submitting to IETF.
8404 * Implemented TOPIC command to server in silcd/command.c.
8406 * Added two new notify types into lib/silccore/silcnotify.h:
8407 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
8408 notify nickname change and topic setting/change on a channel.
8410 * API change of command_reply operation in client library. The
8411 application gets now the status type received from server as well.
8413 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8415 * Removed the function just added to lib/silcutil/silcschedule.[ch].
8417 * Cras fixed and optimized the packet handling even further and
8418 it should work now. Minor change to the prototype of function
8419 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
8421 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8423 * Added new function into lib/silcutil/silcschedule.[ch]:
8424 silc_schedule_with_fd to select() a specified fd. The function
8425 returns after timeout expires or data arrives or goes. The
8426 function is used by packet routines to wait that all data is
8427 received from network.
8429 * Fixed data reading from network in lib/silccore/silcpacket.c.
8430 The code now assures that all data is read from the fd and then
8431 continues packet processing. This was a bug fix since the code
8432 used to drop some data in some circumstances.
8434 * Added new function into lib/silcclient/client.[ch]:
8435 silc_client_start_key_exchange to start key exchange after
8436 connection has been established to server. The code internally
8437 now uses this funtion but its main purpose was to provide it
8438 for applications that perform their own connecting. After
8439 application has created a connection it merely calls this
8440 function to start the key exchange between client and server.
8441 The library takes care of everything else after that.
8443 Updated also lib/silcclient/README to explain the usage of
8446 * Do not send to application information that connection has
8447 been established. Application gets notified it by connect
8450 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8452 * Applied cras's patch to add silc_schedule_one function. The
8453 function runs scheduler once and returns.
8455 * Fixed the scheduler after cras messed it up. The timeout
8456 handling works now as it's supposed to work.
8458 * Added into lib/silccore/ silcnotify.h to include notify
8459 message types support. Changed silc_server_send_notify*
8460 functions, in server.[ch], to support those new notify types.
8461 Added the support for the notify types into client library,
8462 as well. Added new notify client operation into ops.h in
8465 * Changed silc_server_packet_send_to_channel to send normal
8466 packets instead of just channel message packets. The function
8467 is now used to send the notify packets to channels. It is not
8468 used to send channel message packets anymore, as server never
8471 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
8472 va_arg()s as it seems to require it nowadays. I guess, if SILC
8473 is compiled with older va_arg() the new code should work anyway.
8475 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8477 * Splitted core library. Core library (lib/silccore) includes
8478 now only SILC protocol specific core (and common) components.
8479 Created new utility library (lib/silcutil) that includes more
8480 generic purpose stuff. The stuff for util library was taken
8481 from the old core library. This was minor and easy split.
8483 * Created SILC Client Library (lib/silcclient) that includes
8484 implementation of the SILC client without user interface. This
8485 was major move from silc/ directory. The code has been changed
8486 so that it is transparent towards the user interface. The
8487 silc/ directory includes now the same user interface as before
8488 and it uses the new client library. Read lib/silcclient/README.
8489 Basicly, the client library performs everything else related
8490 to SILC except user interface handling. Also, configuration
8491 files are considered to be part of user interface and library
8492 does not handle them.
8494 This change also changed a lot of structures, function naming etc.
8495 Most important change was that SilcClientWindow object was
8496 renamed to SilcClientConnection in the client library. Created
8497 also new file lib/silcclient/ops.h. Also added new files
8498 silc/local_command.[ch] and silc/client_ops.[ch].
8500 All these changes were made to make it easier for user interface
8501 designers to create what ever user interface for the SILC client
8504 It is also expected that the server will be moved to lib
8505 directory as well and SILC Server Library will be created;
8506 sometimes in the future.
8508 * Removed Local commands from lib/silccore/silccommand.h as
8509 they are application specific and new client library does not
8510 handle any of those anymore.
8512 * Several functions moved to lib/silcutil/silcutilc.[ch] from
8513 old client implementation in silc/.
8515 * Added support for callback functions in SILC_LOG_* macros.
8516 Application can now set its own callbacks that will be called
8517 instead of using the default functions that will always print
8518 the debug messages to stderr (or stdout). Also, debugging can
8519 now be disabled by setting silc_debug to FALSE and re-enabled by
8520 setting it to TRUE. Note, that logging will still work even
8521 if debugging is disabled.
8523 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
8524 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
8525 silc_log_reset_debug_callbacks.
8527 * To enable debugging in silc client one must give now -d
8528 option on command line.
8530 * Changed silc_schedule_init to automatically allocate task queues
8531 if they are not allocated before calling it.
8533 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8535 * Added GMP 3.1 into math library.
8537 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8539 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
8540 a channel in SILC network. The packet is used by servers and
8541 routers to notify other routers that user has left a channel.
8542 This little feature was missing until now. Added the feature
8543 to protocol specification as well.
8545 Added functions: silc_server_send_remove_channel_user and
8546 silc_server_remove_channel_user into server.[ch].
8548 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
8549 lib/silccore/silcpacket.h. However, they are not implemented
8552 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8554 * Fixed joining to a channel and sending channel messages
8555 between server and router. The channel message sending should
8556 now work inside a cell.
8558 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8560 * Fixed the private message sending between server and router.
8561 The private message sending should now work inside a cell.
8563 * Added silc_server_replace_id into server.[ch] to replace
8564 existing ID in the SILC network.
8566 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
8567 and silc_idlist_replace_server_id into idlist.[ch] in server.
8569 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8571 * Fixed the server to server connections. Server can again now
8572 connect to router. Router to router connections probably does
8575 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8577 * Added dynamic protocol registering support. Now protocols can
8578 registered and unregistered on the fly. Patch by cras.
8580 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8582 * Added lib/contrib directory to hold routines that some platforms
8583 don't have but are needed by SILC.
8585 * Added getopt.c, getopt1.c and getopt.h from GNU C library
8586 into lin/contrib to provide getopt() and getopt_long() for
8587 those who don't have it.
8589 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8591 * Added AWAY command to client. When away message is set and
8592 client receives a private message packet the client automatically
8593 replies to the sender with the away message.
8595 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
8596 bug seemed to be the cause of recent problems when compiling
8599 * Added version detection support to SKE protocol specification
8600 and added the new changes to the SKE implementation as well.
8601 There were other minor changes in the SKE protocol as well.
8603 Many changes in lib/silcske/silcske.[ch] and in
8604 lib/silcske/payload.[ch].
8606 * Added ^U functionality, clear input line. Patch from cras.
8608 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8610 * Mainly small bugfixes on core library. Fixed some debugging
8611 logging and buffer overflow in silclog.c.
8613 * Updated config.sub and config.guess on the distribution tree.
8615 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8617 * Added command lagging support in server. Client may execute
8618 commands now only once in two seconds.
8620 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8622 * Optimized packet reception. MAC computation and checking is now
8623 also more optimized. A lot previously duplicated code is now
8624 used as generic by both client and server.
8626 * Fixed key pair generation in clientutil.c
8628 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8630 * Added into lib/silccore/silcbufutil.[ch] new function;
8631 silc_buffer_realloc.
8633 * Moved generic packet sending/encryption functions to
8634 lib/silccore/silcpacket.[ch] from client and server. Some
8635 rewriting of the functions.
8637 * Moved all generic packet reception/decryption functions to
8638 lib/silccore/silcpacket.[ch] from client and server. The
8639 packet processing is now much cleaner in both client and server.
8640 These were major changes in both client and server.
8642 * Created many common functions in server to do packet sending.
8643 Previously code were duplicated a lot, this has been removed
8646 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8648 * Rewrote major parts of the ID cache system. Don't know
8649 whether it is better now or not but at least the API is more
8652 * Major rewrite on ID cache stuff on client because of the ID
8653 cache API changes. Added idlist.c to client.
8655 * Also major rewrite on ID cache stuff on server as well.
8656 Major rewrite of idlist.[ch]. SilcXXXList's are now named
8657 SilcXXXEntry's. We won't keep anymore idlist specific pointers
8658 in hand, instead they are all put into the ID cache system now.
8659 All server_idlist_* routines uses ID cache now instead of
8660 traversing its own lists (those lists does not exist anymore).
8661 SilcIDList though still exists. Also, SilcXXXEntry's are
8664 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8666 * Finally made the SKE implementation compliant to the protocol
8667 specification. All mp integers are now binary encoded as
8668 opposed being HEX encoded.
8670 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
8673 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
8674 functions: silc_[encode/decode]_pem. Also added function
8675 silc_encode_pem_file to PEM encode with newlines ('\n') for
8678 * SILC public keys are now encoded either PEM or binary. Same
8679 option is for private keys as well. By default private keys
8680 are binary encoded and public keys PEM encoded. Silly HEX
8681 encoding were removed.
8683 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
8684 function to create fingerprints.
8686 * Fixed a bug in SHA1; does not change the original data anymore.
8688 * Partly implemented INFO command on client and server side.
8689 Fixed CLEAR command. Changes to SERVER command; show current
8690 server(s) when giving command without arguments. Added
8691 VERSION command to client.
8693 * Added check to server that unregistered connections cannot
8694 execute commands (unless it is specificly allowed).
8696 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8698 * Fixed screen refresh.
8700 * Fixed channel joining bug from client. On some circumstances
8701 client tried to join to a channel it had already joined.
8703 * Added public key verification process into client's protocol.c.
8704 The client now verifies the public key from user and saves
8705 it into ~./silc/serverkeys/ directory.
8707 Added into: clientutil.[ch]: silc_client_verify_server_key.
8709 * Changed SKE protocol's silc_ske_initiator_finish function
8710 to accept callback function that verifies the received public
8711 key. Removed old silc_ske_verify_public_key function.
8713 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8715 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
8716 silc_pkcs_private_key[_data]_set.
8718 * Made the password and public authentication more cleaner in
8719 server's protocol.c.
8721 * Removed historic and obsolete protocol `channel_auth' from
8722 both client and server.
8724 * Removed wrong way of sending command status messages from
8725 server to client in server's command.c. The old way violated
8726 protocol specification.
8728 Changes to silccore/silccommand.[ch]: removed
8729 silc_command_encode_status_payload -> not needed anymore,
8730 changed silc_command_encode_payload_va to accept extra
8731 argument on variable argument list. The argument type must
8732 now be provided to the function. Also, added new function:
8733 silc_command_encode_reply_payload_va which is same as
8734 normal command_encode_payload_va except command status type
8735 is provided as extra argument.
8737 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8739 * Added ~./silc directory handling. The directory includes the
8740 public and private keys for the client.
8742 Added silc_client_check_silc_dir, silc_client_create_identifier
8743 and silc_client_load_keys.
8745 * Implemented SILC protocol compliant public key. Added public
8746 and private key saving to and loading from files.
8748 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
8749 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
8750 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
8751 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
8752 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
8754 Implemented: silc_pkcs_save_[public/private]_key[_data] and
8755 silc_pkcs_load_[public/private]_key.
8757 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8759 * Added silc_server_get_route (route.[ch]) to get connection
8760 data for the fastest route for given ID.
8762 * Implemented INVITE command on client and server. The command
8763 were re-defined in the SILC Protocol Specification and the
8764 implementation now complies with the specification.
8766 * Implemented PING command on client and server.
8768 * Implemented NAMES command on client and server. The server side
8769 supports currently only normal server not router server yet.
8770 Some changes to NAMES definition in SILC protocol specification.
8772 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8774 * Implemented LEAVE command on client and server.
8776 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
8777 again. This change was made to the protocol as well. Server
8778 should not violate the protocol specification anymore.
8780 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8782 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
8783 was tested. SOCKS4 was not but should work anyway.
