1 Sun Jun 23 17:32:31 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
3 * Don't do SILC_STRING_LANGUAGE encoding if the outbuffer
4 is NULL since seems that on some platforms NULL is allowed
5 and on some it's not. Fallback encoding is used instead.
6 Affected file lib/silcutil/silcstrutil.c.
8 * Fixed statistics updating for incoming server connection
9 which could cause problems when re-connecting. Affected
12 * Preliminary backup router support for standalone router
13 added. Affected files in silcd/.
15 * Mark server connections in backup router disabled before
16 and after backup protocol. Affected file is
17 silcd/server_backup.c.
19 * Added support for reconnecting to remote server connection
20 even if the protocol fails, and if the configuration wants
21 us to keep trying to connect anyway.
23 Server connection is not allowed to backup router if
24 backup router does not have connection to primary router yet.
26 Affected file is silcd/server.c.
28 Sat Jun 22 21:34:59 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
30 * Added silc_client_udpate_server function to update changed
31 server info. Affected file lib/silcclient/idlist.[ch].
33 * Added check for server entries that are being resolved when
34 notify is received. If being resolved, handle the received
35 notify only after it's resolved so that all notifys are
36 handled in same order as received from the server.
38 Added similar resolver check to channel entries. Every
39 notify that cause resolving of any information that affects
40 channel entry marks the channel entry in waiting state.
41 After whatever resolving is over the waiters are signalled
42 and only then the notifys are handled in the same order
43 as delivered from the server.
45 Affected files are lib/silcclient/idlist.[ch], and
48 * Fixed KILLED notify handling in normal server. Affected
49 file silcd/packet_receive.c.
51 * Added SILC_IDLIST_STATUS_LOCAL which indicates that entry
52 is locally connected, or was locally connected (but may
53 be detached and connection is not active). Added also
54 SILC_IS_LOCAL for checking this status. Affected files
55 silcd/idlist.h, silcd/packet_receive.c, silcd/server_util.c,
56 silcd/server.c and silcd/server_internal.h.
58 Sat Jun 22 17:06:58 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
60 * Don't send or handle TOPIC_SET if topic is already set and
61 is same as being set. Affected files silcd/command.c and
62 silcd/packet_receive.c.
64 * Fixed CMODE change rights checking to work correctly when
65 removing modes by operator. Affected file is
68 * Fixed some handling with New Channel packet in router and
69 fixed some CMODE_CHANGE notify handling in server and router.
70 Affected file is silcd/packet_receive.c.
72 * Changed "disconnect" client operation to include the
73 reason of the disconnection and optional disconnection
74 message. Affected file lib/silcclient/silcclient.h.

81 * All CMODE_CHANGE and CUMODE_CHANGE notifys are now sent back
82 to the sender of the notify too, to avoid situation where two
83 notifys are in the network at the same time going to oppsite
84 directions. Affected file silcd/packet_receice.c.
86 Fri Jun 21 10:00:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
88 * Delete the client from channel even if the cilent->id is
89 NULL. It was possible that client was deleted without
90 removing from channels (theoretically at least). Affected
91 file silcd/server.c and silcd/server_util.c.
93 * Free the client data too when resuming is not successful.
94 Affected file silcd/packet_receive.c.

99 * Added SILC_PRIMARY_ROUTE and SILC_BROADXAST macros to
100 silcd/server_internal.h. SILC_PRIMARY_ROUTE Returns pointer
101 to the primary router connection, the other one returns
102 TRUE if packet must be broadcasted to network.
104 * All notifys that are destined to primary router (to network)
105 are now automatically sent to backup routers even if the
106 router is standalone (and has backup router). Affected files
109 * Added --without-irssi and --without-silcd configuration
110 options for disabling the compilation of these applications.
111 Affected file configure.in.pre and prepare.
113 Thu Jun 20 13:48:15 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

137 command reply from router, on normal server. Otherwise
138 joinig +a channels from normal server is not possible.
139 Affected file silcd/command.c.
141 * Fixed a bug in TOPIC_SET notify handling. The notifier
142 may be other than client too, like server or channel.
143 It expected it to always be only client and ignored the
144 notify. Affected file silcd/packet_recieve.c.
146 * Removed some (unnecessary) debug printing from
147 lib/silccore/silcid.c and lib/silccore/silcargument.c.
149 * Do not force CMODE_CHANGE when server is announcing new
152 Router announces stuff only after server reannounces channel
153 after CHANNEL_CHANGE notify.
155 These fixes optimizes the announcing procedure, and perhaps
156 fixes some problems too. Affected file silcd/packet_receive.c.
158 * Fixed SERVER_SIGNOFF sending to local clients. It was
159 totally broken and sent the notify to all local clients,
160 instead of only to those that was on same channel as the
161 signing off clients. Affected file silcd/server_util.c.
163 * Added -D option to server. It can be used to give debug
164 level. The levels are from 0 - 99, and are predefined for
165 smooth server debugging. (see silcd.c for the predefined
166 levels). Affected file silcd/server.c.
168 Wed Jun 19 16:01:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

587 or user mode changes the watcher will be notified of this
588 change. Added SILC_COMMAND_WATCH command, added new
589 notify type SILC_NOTIFY_TYPE_WATCH to deliver the watch
590 notifications. Updated the protocol specs and implemented
591 this to library, client and server. Protocol TODO #21.

635 cause SILC_NOTIFY_TYPE_ERROR notify message to the sender.
636 Updated the protocol specs and the code in server. The
637 affected file is silcd/packet_receive.c.
639 Mon Apr 15 19:57:57 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
641 * Added new notify type SILC_NOTIFY_TYPE_ERROR and specified
642 that it is used to send error notifys if error occurs during
643 some SILC packet processing, except commands. The error
644 types are same as for command reply types. Defined that
645 if private message is sent to unknown Client ID the error
646 is sent in SILC_NOTIFY_TYPE_ERROR instead of command reply.
647 Updated the protocol specs and code. Affected files are
648 lib/silccore/silcnotify.h, added lib/silccore/silcstatus.h,
649 lib/silcclient/client_notify.c, silcd/packet_receive.c,

651 SilcCommandStatus to SilcStatus.
653 * Defined the use of extra WHOIS attributes in WHOIS command.
654 The <Requested Attributes> (defined in a separate document)
655 can be used to request additional information about user
656 not returned by standard WHOIS command. Defined that server
657 can send WHOIS command directly to client. Client provides
658 the requested attributes to the server. Updated the protocol
659 specs. Protocol TODO #4. Implementation is not done yet
662 * Renamed function silc_client_command_status_message to
663 silc_client_status_message. Affected files are

687 * Added resolve_cmd_ident field to the SilcClientEntry structure
688 too so that if the entry is for example being resolved so
689 another command may attach to the same pending command reply
690 without requiring to resolve the same entry again. Added
691 support for adding multiple pending commands for one
692 command idenfier. Affected files lib/silcclient/command.[ch],
693 lib/silcclient/command_reply.[ch], lib/silcclient/idlist.h.

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

724 mask to the client. Updated protocol specs and the server.
725 Affected file is silcd/command.c.
727 * Added SILC session detachment/resuming support. It is possible
728 to detach by closing the network connection and then re-connect
729 and resume to the old client session. Added DETACHED user
730 mode that server will set for detached client. Added new
731 packet RESUME_CLIENT which is used to perform the resuming
732 process. Added DETACH command. Updated the protocol specs,

740 mask to the client. Updated protocol specs and the server.
741 Affected file is silcd/command.c.
743 * Changed the Killer's Client ID in KILLED notify to be just
744 any ID payload since router server is allowed to kill as well.
745 Updated protocol specs, client libary and server. Affected
746 files are lib/silcclient/client_notify.c, silcd/packet_receive.c,
747 and irssi/src/silc/core/client_ops.c.

762 may set to itself to tell server not send channel messages.
763 Other packets such as channel key packets are still sent.
764 Protocol TODO #23. Updated the protocol specs, client and
765 server. Affected files are lib/silccore/silcmode.h,
766 irssi/docs/help/in/cumode.in, lib/silcclient/command.c,

770 Mon Apr 8 23:57:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
772 * Redefined the Status Payload to include now two 8 bit fields,
773 instead of one 16 bit field. This now makes it possible to
774 send list of errors. Updated the protocol specs and the code
775 in core library, client library and server. Protocol TODO #1.
776 Affected files are lib/silccore/silccommand.[ch],
777 lib/silcclient/command_reply.[ch], silcd/command.c,
778 silcd/command_reply.c and silcd/packet_receive.[ch].
780 Mon Apr 8 19:57:40 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
782 * Added config parse status SILC_CONFIG_EPRINTLINE, this status
783 must be handled by the application and should tell the application
784 that an error message was already printed, and it should print the
785 config coords (line, filename, ...). Affected files are
786 silcd/serverconfig.c, lib/silcutil/silcconfig.[ch].
788 * Added local macro SILC_SERVER_CONFIG_ALLOCTMP to make the
789 server config parsing code more readable.

807 Sun Apr 7 17:07:59 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
809 * Added STATS command to the protocol after all, to return
810 various statistical information about the network. It can
811 be used by clients to retrieve statistical information, and
812 servers may use it to to fetch cell and network wide
813 statistics from router. Updated the protocol specs and
814 implemented it to the server. Protocol TODO #16.
815 Affected files are lib/silccore/silccommand, silcd/command.[ch],
816 silcd/command_reply.[ch].
818 Sat Apr 6 17:08:58 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
820 * The LIST command reply in client libary now adds new channel
821 entry if the returned channel doesn't exist yet in cache,
822 and returns the channel entry to the application in the
823 command_reply client operation. Affected file is
824 lib/silcclient/command_reply.c.
826 * Changed the channel message payload's MAC generation to
827 include the IV in the MAC as well. This way all relevant
828 parts of the channel message payload are authenticated also
829 with the channel message MAC (and not only by packet MAC).
830 Causes incompatibility with 1.0 protocol. Protocol TODO #7.
831 Affected file is lib/silccore/silcchannel.c.
833 * Fixed the SKE to save the remote version, since the
834 silc_ske_parse_version mistakenly checked wrong version,
835 after it replaced the start payload. Affected files are
836 lib/silcske/silcske.[ch].
838 Fri Apr 5 16:03:03 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

858 * Changed the silc_client_close_connection interface to not
859 need the SilcSocketConnection which should not be visible
860 to application. Affected files are lib/silcclient/client.c
861 and lib/silcclient/silcclient.h.
863 * Rewrote the text for Private Message Key Payload in the
864 protocol specification. Protocol TODO #11.
866 Wed Apr 3 16:24:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
868 * Upgraded the protocol version to 1.1, updated protocol specs
871 * Added the nickname as new argument to NICK_CHANGE notify and
872 added it to protocol specs and implemented it to client and
873 server. Protocol TODO #3. Affected files are silcd/idlist.[ch],
874 silcd/command.c, silcd/packet_receive.c, packet_send.[ch], and
875 lib/silcclient/client_notify.c.

880 silcd/packet_receive.c, packet_send.[ch],
881 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
882 The killer's client entry is now returned to application in
883 the `notify' client operation.
885 * Fixed the Max Argument fields that had too large value set
886 in the protocol specs. Protocol TODO #14.
888 * Added the LEAVE command reply to return the ID of parted
889 channel. Updated protocol specs and implemented it to the
890 client and server. Protocol TODO #15. Affected files are
891 silcd/command.c, lib/silcclient/command_reply.c. The channel
892 entry is now returned to application in the `command_reply'

896 and in server to use the silc_parse_version_string. Affected
897 files are lib/silcclient/protocol.c, silcd/protocol.c.
899 * Added SILC_STATUS_ERR_NO_CHANNEL_FOPRIV error status to few
900 commands that was missing it, and updated protocol specs and
901 the server implementation. Protocol TODO #10. The affected
902 file is silcd/command.c.
904 * Defined new message flags SILC_MESSAGE_FLAG_REPLY to be
905 generic reply to a generic request (REQUEST flag), and
906 SILC_MESSAGE_FLAG_DATA to send any kind of data in a generic
907 way. A draft-riikonen-silc-flags-payloads-00.txt is written
908 to define the payload for DATA flag. Added the flags to
909 the implementation. Protocol TODO #9. Affected file is
910 lib/silccore/silcchannel.h.
912 Changed the client library to return the message length

917 and lib/silcclient/client_ops_example.c.
919 * Added two new channel modes: SILC_CMODE_SILENCE_USERS
920 and SILC_CMODE_SILENCE_OPERS which can be used to moderate
921 the channel. Updated protocol specs and impelemented this
922 to client and server. Protocol TODO #6. Affected files are
923 silcd/packet_receive.c, server_util.c, lib/silcclient/command.c,

926 Added new options m and M to CMODE command in Irssi SILC
927 client to set these modes.
929 * Deprecated all administrative commands from SILC protocol
930 since they are highly implementation specific commands.
931 Updated protocol specs. Moved the old commands in
932 implementations to private range of command types. Affected
933 files are silcd/command.c, lib/silcclient/command.c and
934 lib/silcclient/command_reply.c. Protocol TODO #8.

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

977 totally saved 16 bytes of memory per context after optimization.
978 Affected files are lib/silccore/silcpacket.[ch].
980 * Made strict checks for valid SILC IDs. Affected file is
981 lib/silccore/silcid.c.
983 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
985 * Changed the object argument for silc_cipher_register,
986 silc_hash_register, silc_hmac_register and silc_pkcs_register
987 to const. Affected files are lib/silccrypt/silccipher.[ch],
988 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
990 * Changed the silc_get_username and silc_get_real_name to
991 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
993 * Fixed the Irssi SILC Client to use the silc_get_username and
994 silc_get_real_name insted of glib routines since the glib
995 routines only corrupt stack. Fixes the Irssi SILC to work in
996 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
998 * Fixed the Irssi to not use g_get_home_dir since it crashes
999 or returns garbage on cygwin and corrupts stack. Added function
1000 get_home_dir to Irssi routines. Affected files are
1001 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
1003 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1006 entry structure. Optimized SilcTask structure. Optimized
1007 SilcPacketContext structure.
1009 Affected files lib/silcsftp/sftp_fs_memory.c,
1010 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
1012 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1014 * And yet again reverted back the config thing since Johnny
1015 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
1018 * Fixed memory leaks from config object. Affected files are
1019 silcd/serverconfig.[ch].
1021 * Added support for adding new connections to the server in rehash.
1022 After rehash they take effect.
1024 Added support for changing the maximum allowed connections in
1025 rehash. The number can grow but going smaller is not supported.
1027 Added function silc_server_num_sockets_by_remote to the
1028 silcd/server_util.[ch].
1030 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
1032 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

1035 public/private key and removed further checks in the code.
1036 Affected files are silcd/serverconfig.[ch], server.c.
1038 * Moved functions silc_server_drop() and silc_server_daemonise()
1039 from server.c to silcd.c since they are stricly related to
1040 the application activity.
1042 * Reverted a small part of the automatic ref/unref since
1043 it caused a double unref in some situations. Affected
1044 files are silcd/silcd.[ch], server.c, serverconfig.c.
1046 * Added some .cvsignore files in the lib directory.
1048 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1050 * Fixed silc_net_gethostbyaddr to correctly resolve by
1051 address. Affected file lib/silcutil/silcnet.c.
1053 * Fixed the notify relaying to client. The HMAC to be used
1054 with relayed packets ws wrong and caused decryption failure
1055 at the client end. Affected file is silcd/packet_receive.c.
1057 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1059 * Created new branch silc_protocol_1_0_branch.
1061 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
1063 * Changed the silc_server_config_* routines to be SilcServer
1064 independent. They are now officially application specific code
1065 and not part of generic server implementation. Affected files
1066 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
1068 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1070 * Added automatic referencing of config context in the
1071 silc_server_config_alloc, and automatic unreferencing in the
1072 silc_server_config_destroy. Affected files are
1073 silcd/serverconfig.[ch], silcd/silcd.c.
1075 * Fixed the silc_log_quick handling in the logging routines.
1076 It didn't log quickly when it was TRUE. Affected file is
1077 lib/silcutil/silclog.c. Also the flush delay was set even
1078 if it was 0 in config file. Affected file is
1079 silcd/serverconfig.c.
1081 * Added support for changing key pair of the server in rehash.
1082 Affected file silcd/server.c.
1084 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1086 * Fixed the TOPIC_SET notify to not cras. It changed the topic
1087 too early, before getting the channel entry. Affected file
1088 is silcd/packet_receive.c.
1090 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1092 * Added functions silc_server_config_[ref/unref], these are used
1093 to prevent that the config object is destroyed.
1095 No longer directly affect global variables silc_log_quick and
1096 silc_log_delay, they are first cached inside the config object
1097 and then applied with silc_server_config_setlogfiles().
1099 silc_server_config_set_defaults() is now internal to
1100 serverconfig.c, there are no reasons to show this internal stuff
1103 Affected files are silcd/serverconfig.[ch].
1105 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
1106 fprintf's to stderr, since some code may be executed again after
1107 the server went into the background. Affected files are
1110 * Added rehash support. Added function silc_server_rehash() that
1111 will perform all the basic tasks of the rehashing procedure.
1113 * Added command line option `-x, --hexdump'. This will enable the
1114 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
1115 The option `--hexdump' implies `--debug'.
1117 * Fixed a bad bug in the logging APIs (silcutil library) where
1118 the application would crash after calling silc_log_reset_all().
1120 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1122 * Fixed the KICKED notify handling in client library to
1123 correctly remove the channel and all entries from the
1124 channel when I was kicked. This bug crashed the client.
1126 Fixed yet another but in KICKED notify handling to remove
1127 the kicked client correctly from the channel.
1129 Affected file is lib/silcclient/client_notify.c.
1131 * Fixed a minor bug in looking up correct client entry
1132 in KICKED notify in server. Affected file is
1133 silcd/packet_receive.c.
1135 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
1136 sources correctly to distribution. Fixes --with-gmp option.
1138 * Removed the manual rehashing from ID Cache, and changed it
1139 to use the SILC Hash Table's auto rehash feature. Affected
1140 file is lib/silccore/silcidcache.c.
1142 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1144 * Fixed a bug in the silc_client_nickname_format function that
1145 handles the multiple same nickname formatting. Two clients
1146 with same nickname caused problems after the first one left
1147 and rejoined. It didn't format the nickname correctly.
1148 Affected file is lib/silcclient/idlist.c.
1150 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1152 * Don't change the topic if olod topic is same as new one.
1153 Affected file is silcd/packet_receive.c.
1155 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1157 * Added cross-reference support to the SILC Documentation
1158 generator. All types across all HTML files are now cross-
1159 referenced. Affected files util/robodoc/generator.c and
1160 scripts/silcdoc/silcdoc.
1162 * Added file lib/silcutil/silctypes.h to include all the
1163 arithmetic type definitions and some macros. Removed
1164 includes/bitmove.h and moved macros to silctypes.h.
1166 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1168 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
1170 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1172 * Added `type' argument to silc_id_payload_parse_id function which
1173 now returns the type of the ID to the sent pointer. Affected
1174 file is lib/silccore/silcid.[ch].
1176 * Added check for CMODE_CHANGE notify type that mode change is
1177 allowed by the sender. Affected file silcd/packet_receive.c.
1179 * Added check for CUMODE_CHANGE notify type that mode change is
1180 allowed by the sender. Affected file silcd/packet_receive.c.
1181 Added the ID type as CUMODE_CHANGE notify type as argument
1182 to the `notify' client operation. Affected files are
1183 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
1185 * Added function silc_client_add_server to the client library.
1186 Added support for resolving also channel and server info when
1187 received unknown entity in notify packet. Affected files are
1188 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
1190 * Added function silc_command_get_status to return the command
1191 status from the command reply's argument payload. Affected files
1192 are lib/silccore/silccommand.[ch].
1194 * Added check for KICKED notify type that the kicking is
1195 allowed by the client. Affected file silcd/packet_receive.c.
1197 * Created function silc_get_input which can be used to get input
1198 (echo on or off) from user on command line. Affected files are
1199 lib/silcutil/silcutil.[ch].
1201 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1203 * Optimized silc_server_packet_relay_to_channel function.
1204 Added new function silc_channel_message_payload_encrypt which
1205 can be called directly if channel message payload needs to
1206 be encrypted and is already encoded (no need to call _encode
1207 function). Packet relaying is now done by router without any
1208 extra memory allocations. Affected files are
1209 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
1210 silcd/packet_send.c.
1212 * Fixed the INVITE notify handling. It took wrong arguments
1213 as invite list and invite delete. Affected file is
1214 silcd/packet_receive.c.
1216 * Added check for TOPIC_SET notify type that the topic change is
1217 allowed by the client. Affected file silcd/packet_receive.c.
1219 * Added check for INVITE notify type that inviting is allowed by
1220 the client. Affected file silcd/packet_receive.c.
1222 * Changed the silc_server_client_on_channel to return the
1223 SilcChannelClientEntry as well. Moved the function
1224 silc_server_check_cmode_rights to server_util.[ch].
1225 Affected files are silcd/server_util.[ch], silcd/command.c.
1227 * Added function silc_server_check_umode_rights to check whether
1228 changing client's user mode is allowed. Added check for
1229 UMODE_CHANGE notify type that the umode change is allowed
1230 by the client. Affected files are silcd/server_util.[ch],
1231 silcd/packet_receive.c and silcd/command.c.
1233 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1235 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
1236 ID length. It ignored that ID can be IPv6 based as well.
1237 Affected file lib/silccore/silcpacket.h.
1239 * Fixed the silc_id_id2str and silc_id_str2id to take the
1240 IPv6 address offset's into consideration. Affecte file is
1241 lib/silccore/silcid.c.
1243 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1245 * Fixed the internal Unix scheduler functions to check for
1246 NULL context they may receive. The affected file is
1247 lib/silcutil/unix/silcunixschedule.c.
1249 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
1251 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
1252 can specify different directory with --home command line
1253 parameter. Affected files irssi/src/silc/core/client_ops.c,
1256 * SILC-specific commands aren't now executed if the active server
1257 isn't of SILC-type, so there won't be problems with having
1258 IRC and SILC protocol support in same client. Affected files
1259 irssi/src/silc/core/silc-channels.c, silc-servers.c,
1262 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1264 * Improved the signal support in SILC Schedule. Added new
1265 function silc_schedule_signal_call which is used by application
1266 to mark a signal to be called. It is now safe to perform
1267 any kind of tasks in signal callbacks since it is guaranteed
1268 that the application specified signal callback is called
1269 after the signal is over. Affected files are
1270 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
1272 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1274 * Added `name' field to SilcChannelPrivateKey to represent
1275 application given name for the key. Moved also the context from
1276 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
1277 Added the `name' argument also to the function
1278 silc_client_add_channel_private_key.
1280 Added function silc_client_current_channel_private_key to set the
1281 current channel private key in use.
1283 Added "change" command to KEY command which can be used to change
1284 the current channel private key. Bound the command also to
1285 alt+K (Alt+Shift+k).
1287 Also affected files lib/silcclient/client_channel.c,
1288 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
1290 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1292 * Added silc_rng_get_byte_fast function in to the
1293 lib/silccrypt/silcrng.[ch].
1295 * Changed the interface of silc_packet_assemble and the
1296 silc_packet_send_prepare. If silc_packet_assmble is now
1297 called the application does not call silc_packet_send_prepare
1298 because the library will call it automatically. These
1299 interfaces now also return a reference to the outgoing buffer
1300 which includes the assembled packet, which the application can
1301 use to encrypt the packet.
1303 Affected files are lib/silccore/silcpacket.[ch],
1304 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
1305 silcd/packet_send.c, server_backup.c and packet_receive.c.
1307 * Fixed a packet sending bug on very high load, where outgoing
1308 packet queue wasn't handled correctly and packets got corrupted.
1309 Affected files are lib/silcutil/*/silc*sockconn.c,
1310 lib/silcclient/client.c and silcd/server.c.
1312 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1314 * Added macro SILC_PACKET_DATALEN which can be used during
1315 packet assembling to check whether the data to be added to
1316 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
1317 len is truncated until it fits it.
1319 Added checks for maximum length of channel message payload and
1320 private message payload also.
1322 Added checks for maximum packet length in server and in
1325 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
1326 lib/silcclient/client.c, lib/silccore/silcchannel.c and
1327 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
1328 lib/silcclient/client_prvmsg.c.
1330 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1332 * Added silc_server_packet_queue_purge call to the
1333 silc_server_disconnect_remote to assure that all data in the
1334 queue before disconnecting is sent to the network. Affected
1335 file silcd/server.c.
1337 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1339 * Added the deleting of server's own ID cache entry to the
1340 silc_server_free function. Free also everything else that
1341 has been allocated in silc_server_init. The affected file
1344 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1346 * Added functions silc_parse_version_string, silc_version_to_num,
1347 and silc_ske_parse_version to parse SILC protocol style version
1348 strings. Affected files lib/silcutil/silcutil.[ch] and
1349 lib/silcske/silcske.[ch].
1351 * Added new configuration params: version_protocol, version_software
1352 and version_software_vendor to specify what version the remote
1353 host must at least be to be able to connect to server. The vendor
1354 string can be regex matched too. Added new function
1355 silc_server_connection_allowed to check maximum number of allowed
1356 connections, and allowed versions for incoming connections.
1357 Affected files are silcd/server.c, server_util.[ch] and
1360 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1362 * Added preliminary support for signals in scheduler. The
1363 signals we care about are now blocked always when the scheduler
1364 is locked. This way we can synchronise the use of signal with
1365 scheduler. It is guaranteed that when signal occurs the scheduler
1366 is not locked, and thus new tasks can be safely added to the
1369 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
1370 to silc_schedule_internal_init and silc_schedule_internal_uninit.
1371 Added new platform specific routines
1372 silc_schedule_internal_signals_[un]block and
1373 silc_schedule_internal_signal_[un]register.
1375 Added new functions to SILC Schedule API:
1376 silc_schedule_signal_[un]register. Each signal that application
1377 is going to use should be registered to the scheduler.
1379 Affected files are lib/silcutil/silcschedule.[ch],
1380 lib/silcutil/*/silc*schedule.c.
1382 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1384 * Check for unauthenticated client and server in the
1385 silc_server_new_client and silc_server_new_server functions.
1386 Affected file silcd/packet_receive.c.
1388 * Added function silc_string_is_ascii to check whether given
1389 string is 7-bit ASCII string. Affected files are
1390 lib/silcutil/silcutil.[ch].
1392 * Added function silc_id_is_valid_server_id into the
1393 silcd/serverid.c and added checking for valid Server ID's in
1394 silc_server_new_server. The Server ID must always be based
1395 on the server's public IP address.
1397 * Added logging of DISCONNECT packet message in the server.
1398 Affected file silcd/server.c.
1400 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1402 * Changed all library interfaces that use Global RNG to also
1403 accept SilcRng as argument. Affected files are
1404 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
1405 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
1406 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
1407 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
1408 lib/silccrypt/rsa.c.
1410 * Added function silc_pkcs_generate_key to the
1411 lib/silccrypt/silcpkcs.[ch] for applications so that they
1412 don't need to do pkcs->pkcs->init calls anymore.
1414 * Remove SilcSocketConnection from the SFTP API since it really
1415 wasn't needed there. The application has the information
1416 saved in its contexts anyway and the SFTP layer doesn't need
1417 know about it. Affected files lib/silcsft/silcsftp.h and
1418 lib/silcsftp/sftp_[server/client].c.
1420 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
1421 The SilcSimContext is not SilcSim.
1423 * Fixed possible buffer overflows in silc_id_render in the
1424 lib/silcutil/silcutil.c.
1426 * On EPOC the global crypto module lists are not used at all
1427 in the crypto library. Added support for using the constant
1428 algorithm list on EPOC. Affected files are
1429 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
1432 * Fixed the handling of third parameter of KICKED notify, since
1433 it was mistakenly updated to SILC Protocol 1.0 even though it
1434 is to be included in 1.1. Since it is not in 1.0 it is not
1435 mandatory, and this fix now handles it only if it is provided,
1436 and it is not error if it is not provided. Affected file
1437 lib/silcclient/client_notify.c.
1439 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1441 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
1442 client. Affected file irssi/src/silc/core/client_ops.c.
1444 * Merged with Irssi 0.8.4 from irssi.org CVS.
1446 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1448 * Check for valid socket connection in client entries before
1449 sending any messages. Fixes a crash, but doesn't fix some
1450 other underlaying bug that is lurking there. Affected
1451 file silcd/packet_send.c.
1453 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
1455 * $usermode, $cumode and $cumode_space expandos shouldn't do
1456 anything with non-SILC server records. Affected file
1457 irssi/src/silc/core/silc-expandos.c
1459 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1461 * Fixed the silc_net_check_[host/local]_by_sock to support
1462 IPv6 bound sockets as well. Now they can return IPv6 addresses
1463 as well. Affected file lib/silcutil/silcnet.c.
1465 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
1466 Affected lib/silcutil/unix/silcunixnet.c.
1468 * Fixed ID rendering (at least on some platforms, not NetBSD)
1469 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
1471 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1473 * Added silc_hash_public_key and silc_hash_public_key_compare
1474 functions to be used with SilcHashTable. They can be used to
1475 hash public keys and compare public keys in hash table. Affected
1476 file lib/silcutil/silcutil.[ch].
1478 * Added support for specifying multiple public keys for Client
1479 connection section in server configuration file. This makes it
1480 possible to accept multiple public keys from same host, or to
1481 make a section that accepts any incoming host, and have the
1482 accepted public keys listed in the section.
1484 Added functions silc_sever_[find/get]_public_key, added the
1485 support for this actually to all connection sections but only
1486 the Client section is currently allowed to specify multiple
1489 Affected files are silcd/server.c, server_internal.h,
1490 command.c, protocol.c, server_util.[ch], packet_receive.c.
1492 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1494 * Merged Irssi 0.8.2 from irssi.org CVS.
1496 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1498 * If silc_debug is TRUE, also output standard logging messages
1499 to stderr with the debug output.
1501 Made silc_log_reset_all() flushing all channels before returning.
1502 Also fixed some documentation typos.
1504 Affected files are lib/silcutil/silclog.[ch].
1506 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1508 * Fixed the server to check correctly the amount of connections
1509 from single host, by checking also the type of the connection.
1510 Fixed also the comparison of number of connections and number
1511 of allowed connections. Affected files are silcd/server.c,
1514 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1516 * Fixed the USERS command reply to save the user's mode on the
1517 channel as well. Fixed JOIN command reply to check whether a
1518 client is on channel already and not join it twice. Affected
1519 file lib/silcclient/command_reply.c.
1521 * Added new file silc-expandos.c into irssi/silc/core/ to return
1522 various stuff for various signal for the statusbar etc. updating.
1523 Now Irssi SILC client prints channel user modes etc. on the
1526 * The user mode (like server/router operator changes) is now shown
1527 on the Irssi SILC client's statusbar. The affected files are
1528 irssi/src/silc/core/client_ops.c, silc-expandos.c.
1530 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1532 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
1533 to SILC_SCHEDULE_[UN]LOCK macros.
1535 * Added more error printing to logs in server code. Affected
1536 files silcd/server.c and silcd/protocol.c.
1538 * Fixed -S option parsing in Irssi SILC Client. Affected file
1539 irssi/src/silc/core/silc-core.c.
1541 * Added silc_buffer_alloc_size function. Affected file is
1542 lib/silcutil/silcbuffer.h.
1544 Tue Mar 5 14:37:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1546 * Changed all silc_[hash|hmac|cipher|pkcs]_default tables to
1547 constants. Affected files in
1548 lib/silccrypt/silcpkcs.[ch], silchash.[ch], silchmac.[ch] and
1551 * Changed the internal SFTP Memory FS table to const. Affected
1552 file lib/silcsftp/sftp_fs_memory.c.
1554 Sun Mar 3 18:37:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1556 * Fixed the buffer formatting and unformatting routines to
1557 check the size of 64 bits types with sizeof(). Affected
1558 file is lib/silcutil/silcbuffmt.c.

1574 silc_net_gethostbyname[_async]. If it is TRUE it will return
1575 IPv6 address over IPv4. If FALSE IPv4 address is returned
1576 even if IPv6 address was found. Affected files
1577 lib/silcutil/silcnet.[ch].
1579 * Added support silc_net_create_connection[_async] to fallback
1580 to IPv4 address if IPv6 address could not be used (like if
1581 it doesn't work on a specific system). Affected file in
1582 lib/silcutil/unix/silcunixnet.c.
1584 Sat Feb 23 15:20:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1590 Wed Feb 20 20:41:01 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1592 * Added automatic extern "C" { ... } for C++ compilers so the
1593 application does not need to define them. Affected file
1594 includes/silcincludes.h.
1596 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
1597 old name went against naming convention. Applications now
1598 include "silcclient.h" instead of "clientlibincludes.h".
1599 Removed includes/clientlibincludes.h, it is redundant now.
1601 * Renamed includes/version.h to silcversion.h.
1603 * Added really preliminary support for OS/2 into the util
1604 library. Only thread & mutex API is implemented, others
1605 are still to be implemented. Created the lib/silcutil/os2/
1606 directory. Created also file includes/silcos2.h.
1608 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1639 * Added `user_count' to the SilcChannelEntry which now tells the
1640 number of users on the channel. The user count is now saved
1641 in normal server of global channels as well. Affected files
1642 silcd/server.c, idlist.h, packet_receive.c and command.c.
1644 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
1645 include file utility functions.
1647 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
1648 instead of calling directly OS routines.
1650 * Fixed NICK change printing in Irssi SILC Client. Fixed
1651 KICKED notify printing in Irssi SILC Client. Affected file
1652 irssi/src/silc/core/client_ops.c.

1660 * ROBOdoc documented the lib/silcske/silcske.h, and improved
1661 the SKE interface a bit.
1663 * Fixed padding problem in PKCS#1. The padding was not actually
1664 random since the random number generator was used incorrectly.
1665 This security bug affects only when encrypting with PKCS#1, and
1666 it is not currently used at all in SILC. SILC only use signing
1667 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
1669 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1727 is now done in silc_core_init() which also fixes autoconnecting
1730 Affected files irssi/src/silc/core/silc-core.c,
1731 irssi/src/fe-text/silc.c.
1733 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1735 * Added new configuration options and blocks:
1736 keepalive_secs, reconnect_count, reconnect_interval,
1737 reconnect_interval_max, reconnect_keep_trying and
1738 require_reverser_lookup. Added ConnectionParam block, and
1739 implemented the connection parameters when connecting as
1740 initiator and when accepting connections as responder.

1752 the connection configuration object from the SilcServerConnection
1753 object instead of finding it during the connecting phase.
1754 Added the configuration object to SilcServerConnection struct.
1755 Affected files silcd/server_internal.h, server.c.
1757 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1759 * Add the client on channel after it was resolved at the
1760 channel message receiving, and it was not already on the
1761 channel. Affected file lib/silcclient/client_channel.c.
1763 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1779 authentication to be set at the same time.
1781 Added `prefer_passphrase_auth' setting in config file which
1782 can be used to set to prefer passwd auth if both passwd and
1783 public key is set. If not set, public key is preferred.
1784 This has effect only when being initiator (responder will try
1787 Added support for authentication with passphrase and public key
1788 at the same time. The passphrase is tried first always since
1789 it is faster to check.
1791 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
1793 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

1839 * Fixed the file transfer's key agreement payload to include
1840 zero port also if the hostname is NULL because it could not
1843 Call file transfer monitor callback now also if error occurs
1844 during key agreement protocol.
1846 Changed the silc_client_file_send interface to return the
1847 SilcClientFileError instead of session id. The session ID
1848 is returned into pointer provided as argument.
1850 Check that the file exists locally before sending the
1851 file transfer request at all.
1853 Affected file lib/silcclient/client_ftp.c, silcapi.h.
1855 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer

1887 the table with foreach callback. The current entry may
1888 become invalid in the callback but it was referenced after
1889 the callback returned.
1891 Do not allow auto rehashing of hash table during the
1892 silc_hash_table_foreach operation, for same reasons as it is
1893 not allowed for SilcHashTableList. Affected files are
1894 lib/silcutil/silchashtable.[ch].

1917 users list to SilcHashTable. The affected files are
1918 lib/silcclient/idlist.[ch].
1920 * Fixed a bug in hash table tarversing. While the hash table
1921 is traversed with SilcHashTableList the table must not be
1922 rehashed. It is now guaranteed that auto rehashable tables
1923 are not rehashed while tarversing the list. Also defined that
1924 silc_hash_table_rehash must not be called while tarversing
1925 the table. Added function silc_hash_table_list_reset that must
1926 be called after the tarversing is over. The affected files are
1927 lib/silcutil/silchashtable.[ch].
1929 * Changed all hash table traversing to call the new
1930 silc_hash_table_list_reset in server and in client library.
1932 * Added function silc_client_on_channel to return the
1933 SilcChannelUser entry if the specified client entry is joined
1934 on the specified channel. This is exported to application as
1935 well. Affected files lib/silcclient/client_channel.c, silcapi.h.

1940 server. The notify for mode change must be sent always and
1941 not only if !cmd->pending. Affected file silcd/command.c.
1943 * Fixed the WHOWAS command's reply sending to support the
1944 lists correctly. Affected file silcd/command.c.
1946 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1948 * When sending JOIN command to router for processing the
1949 sender's old command identifier was not saved back to the
1950 sender's command context, fixed now. The affected file is
1953 * Create the key in JOIN command of the router did not return
1954 the channel key, added check for this. Affected file is
1957 * Fixed a channel ID update bug in JOIN command reply. Do
1958 not directly upgrade the ID but call the function
1959 silc_idlist_replace_channel_id if the ID was changed.
1960 Affected file silcd/command_reply.c.
1962 * Fixed memory leaks from command calling if it would fail.

1990 functions. Affected file silcd/server.c.
1992 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
1993 which ID was changed. This way the router will send the
1994 user list for the channel again, and server won't be in
1995 desync in some rare circumstances. Affected file is
1996 silcd/packet_receive.c.
1998 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>

2050 local entry will always get the unformatted nickname.
2051 Affected file lib/silcclient/idlist.c.
2053 * Fixed some double frees from client library commands.
2054 Affected file is lib/silcclient/command.c.
2056 * Fixed CUMODE command in server to assure that no one can
2057 change founder's mode than the founder itself, there was a
2058 little bug. Affected file silcd/command.c.
2060 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2062 * Removed the SilcClientCommandDestructor from the client
2063 libary, it is not needed anymore. Affected files are
2064 lib/silcclient/silcapi.h, command[_reply].[ch],
2065 client_notify, idlist.c.
2067 * Fixed GETKEY command to first resolve client, and then

2072 * Added silc_client_start_key_exchange_cb and lookup the
2073 remote hostname and IP address before starting the key
2074 exchange with server. The affected file is
2075 lib/silcclient/client.c.
2077 * The server's public key is now saved using the IP address
2078 of the server and not the servername for the filename.
2079 The hostname public key filename is checked as an fall back
2080 method if the IP address based filename is not found.
2082 Fixed the GETKEY command to save the fetched server key
2083 in correct filename.
2085 Print the remote server's hostname now when new key is
2086 received during connection process. Affected file is
2087 irssi/src/silc/core/client_ops.c.
2089 * Return always our own public key to the client if it asks
2090 for it with GETKEY command. Affected file silcd/command.c.
2092 * Removed the use_auto_addr variable from default config
2093 file since it was in wrong section. Affected file is
2096 * Fixed TOPIC_CHANGE notification to not route it when it
2097 was sent using silc_server_send_notify_to_channel function.
2098 Affected file silcd/command.c.
2100 * Fixed silc_server_send_notify_kicked to send the kicker's
2101 Client ID also, it was missing. Affected files are
2102 silcd/command.c, silcd/packet_send.[ch].
2104 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2106 * Do not save client history information in SERVER_SIGNOFF.
2107 Fixes the bug in normal server that it does not detect
2108 the client becoming valid after the server becomes back
2109 online. Affected file silcd/server_util.c.
2111 * Added `sock_error' field into the SilcSocketConnection
2112 context. When error occurs during socket operation (read
2113 or write) the error is saved. Added also new function
2114 silc_socket_get_error to return human readable socket error
2115 message. Affected files are lib/silcutil/silcsockconn.[ch],
2116 lib/silcutil/unix/silcunixsockconn.c, and
2117 lib/silcutil/win32/silcwin32sockconn.c.
2119 * The server now prints the socket error message in the
2120 signoff for client. Affected file silcd/server.c.
2122 * Fixed the `created' channel information sending from router
2123 to server in JOIN command. Checks now whether the channel
2124 really was created or not and set it according that.
2126 Fixed the JOIN command to use the client entry's current
2127 ID during the joining procedure instead of the one it sent
2128 in the command (it is checked though), since it can change
2129 between the packet processing and command processing, and
2130 would just case unnecessary pain in the client end. Affected
2131 file silcd/command.c.
2133 * Fixed a channel key payload sending to use correct channel
2134 ID when the server was forced to change the channel's ID by
2135 router. Router sent the key payload with the old Channel ID.
2136 Affected file silcd/packet_receive.c.
2138 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2140 * Call silc_server_save_channel_key only if the key payload
2141 was provided in the JOIN command's command reply. Affected
2142 file silcd/command_reply.c.
2144 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2146 * Fixed silc_mp_sizeinbase to return the value correctly with
2147 MPI. Affected file lib/silcmath/mp_mpi.c.
2149 * Fixed the stop_server signal to correctly stop the scheduler
2150 and gracefully stop the server when SIGTERM or SIGINT signals
2151 are received. Affected file silcd/silcd.c.
2153 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
2155 * Simple handling of TERM and HUP signals. Also added some log
2156 flushing call around. Affected file is
2159 * Fixed small bugs in silclog.c. Now buffering output will take
2160 effect after 10 seconds since startup: This will ensure that
2161 no important startup messages are lost. Also output redirection
2162 will preserve original format ([Date] [Type] message).
2163 Affected file is lib/silcutil/silclog.c.
2165 * Added two options to the config file, in the logging section:
2166 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
2167 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
2169 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2171 * Do not print the warning about log files not being initialized
2172 more than once to avoid excess logging. Affected file is
2173 lib/silcutil/silclog.c.
2175 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
2176 the SIM copying in make install in Makefile.am.pre.
2178 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2180 * Rewritten silclog APIs. Globally interesting changes follows:
2181 silc_log_set_files() changed to silc_log_set_file().
2182 silc_log_set_callbacks() changed to silc_log_set_callback().
2183 ROBOdoc documented silclog header file.
2184 SilcLogCb now returns bool to wether inihibit the default
2185 handler or not (to keep the old behaviour return always TRUE).
2186 The new APIs should also fix the problem of the
2187 silcd_error.log file that was written in the current directory.
2190 Log files streams will remain opened after silc_log_set_file()
2191 call, means less CPU usage notably on high traffic servers.
2192 File streams are now full buffered, and flushed to the disk
2193 every 5 minutes, lesses HD activity and CPU usage.
2194 Messages can be redirected, allowing admins to configure
2195 one single logfile for all server messages.
2196 the silc_log_quick global variable to activate fast-logging.
2197 Affected files lib/silcutil/silclog.[ch]
2199 * Changed some code to conform new silclog APIs. Affected
2200 files are doc/example_silcd.conf.in, silcd/server.c
2201 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
2204 * Fixed a memory leak that could occur in some situations.
2205 Affected file silcd/serverconfig.c.
2207 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2209 * Added the silc_client_del_client to remove the client from
2210 all channels as well. Affected file lib/silcclient/idlist.c.
2212 * Fixed the client library to correctly remove the client
2213 from all channels when the client entry is being destroyed.
2214 Affected file lib/silcclient/client_notify.c, command.c.
2216 * Added auto-nicking support to the client library. If the
2217 applicatio now sets client->nickname it will be sent to the
2218 server after connecting by the library. This way for example
2219 SILCNICK (or IRCNICK) environment variables will have effect
2220 and always change the nickname automatically to whatever
2221 it is wanted. Affected file lib/silcclient/client.[ch].
2223 * Renamed silc_server_command_bad_chars to the
2224 silc_server_name_bad_chars and moved it to the
2225 silcd/server_util.[ch]. Added also new function
2226 silc_server_name_modify_bad to return nickname that
2227 includes bad characters as new nickname without those
2228 bad characters. This check and modify is now used in
2229 silc_server_new_client when the username is initially set
2230 as nickname, so it must be checked to be valid nickname.
2231 Affected file silcd/packet_receive.c.
2233 * The nickname length is now taken from the packet for real
2234 and not trusted to strlen() since it clearly can return
2235 wrong length for nickname including bad characters. This
2236 also applies to channel names. Affected file silcd/command.c.
2238 * Removed the lib/silcsilm/modules directory. Modules are now
2239 compiled into the lib/silcsim. Fixed the copying of the
2240 modules to follow symbolic links in Makefile.am.pre.
2242 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2244 * Fixed silc_string_regexify list creation. Fixes bugs with
2245 BAN and INVITE commands in server. The affected file is
2246 lib/silcutil/unix/silcunixutil.c.
2248 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2250 * Removed the command destructor entirely from the server's
2251 command and command reply routines. It is not needed, and
2252 its usage was buggy and caused crashes. Affected files are
2253 silcd/command[_reply].[ch].
2255 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2257 * Cancel protocol and NULL sock->protocol if timeout
2258 occurred during protocol. Affected file silcd/server.c.
2260 * Cancel protocol timeouts always before calling the final
2261 callback, to assure that after final callback is called
2262 no other state will be called for the protocol anymore.
2263 Affected file silcd/protocol.c.
2265 * Print error log if incoming connection configuration could
2266 not be found. Affected file silcd/server.c.
2268 * Fixed JOIN command to correctly save the founder mode
2269 to the client on normal SILC server, when the channel
2270 was created by the router. Affected file silcd/command.c.
2272 * Fixed LIST command (hopefully) to send correct reply
2273 packets. Affected file silcd/command.c.
2275 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2277 * The silc_packet_receive_process now returns FALSE if the
2278 read data was invalid packet, and TRUE if it was ok.
2280 The server now checks that if unauthenticated connection
2281 sends data and its processing fails the server will close
2282 the connection since it could be a malicious flooder.
2284 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
2286 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2288 * Make sure the warning about error opening a log file is
2289 printed only once and not everytime it fails (produces
2290 too much useless log). Affected file lib/silcutil/silclog.c.
2292 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2294 * Made the silc_server_daemonise() function more readable.
2295 Affected file silcd/server.c.
2297 * Pid file is now optional, the user may comment it out from
2298 the config file. Removed define SILC_SERVER_PID_FILE, we
2299 don't need a default any longer. Affected file
2300 configure.in.pre, lib/Makefile.am.pre.
2302 * Make some use of the pid file. The server now dies at startup
2303 if it detects a valid pid file on his path. The server would
2304 die anyway in this circumstance, because of the bind() failure.
2305 Affected file silcd/silcd.c.
2307 * No longer compiling lib/dotconf.
2309 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2311 * Fixed JOIN command parsing not to crash. Affected file
2312 lib/silcclient/command.c.
2314 * Fied the NICK_CHANGE notify to add the new client entry
2315 even it is resolved. This removes an <[unknown]> nick
2316 thingy bug in the client. Affected file is
2317 lib/silcclient/client_notify.c.
2319 * Do not try to allocate 0 bytes (efence does not like it)
2320 in lib/silccore/silccomand.c when encoding payload.
2322 * Do not take IRCNICK as nickname in Irssi SILC client since
2323 it is not possible to set nickname before hand connecting
2324 the server (TODO has an entry about adding auto-nicking
2327 * Changed the silc_server_command_pending to check whether
2328 there already exists an pending entry with the specified
2329 command, command identifier and pending callback. This is
2330 to fix IDENTIFY and WHOIS related crashes that may register
2331 multiple pending commands with same identifier. Affected
2332 file silcd/command.c.
2334 * Fixed the server to reconnect to the router even if it
2335 was already reconnecting and EOF was received. This to
2336 fix a possibility that the server wouldn't ever try to
2337 auto-reconnect to the router. Affected file silcd/server.c.
2339 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2341 * Fixed the server's password authentication to use the
2342 length of the locally saved password, and not the one
2343 sent in the packet. Affected file silcd/protocol.c.
2345 * Fixed same password authentication problem in the
2346 Authentication Payload handling routines in
2347 lib/silccore/silcauth.c.
2349 * Yet another password authentication problem fixed with
2350 channel password handling in silcd/command.c.
2352 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2354 * If first character of string in silc_parse_userfqdn is '@'
2355 then do not parse it. Affected file is
2356 lib/silcutil/silcutil.c.
2358 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2360 * Fixed minor bug in IDENTIFY command reply sending, which
2361 caused various weird problems during JOIN when it was
2362 resolving names for users. Affected file silcd/command.c.
2364 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2366 * Fixed the IDENTIFY command reply sending to chech better valid
2367 clients. It was possible to send incomplete list of replies.
2368 Affected file silcd/command.c.
2370 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2372 * Added silc_client_command[s]_[un]register functions now to
2373 dynamically register the commands in client library. Removed
2374 the static table of commands. This allows the client library
2375 to call commands without causing the application to know about
2376 what commands library has called.
2378 Removed the INFO command reply kludge to detect when the command
2379 was called by library. Now library use its own command reply
2380 function for INFO command.
2382 Added function silc_client_command_call to call a command.
2383 Application can use it to call command, not access the structure
2386 Now all commands that are sent by the client library (not
2387 explicitly sent by application) use own command reply functions.
2389 Affected files around lib/silcclient/ and in
2390 irssi/src/silc/core/.
2392 * Fixed the WHOIS command reply sending to chech better valid
2393 clients. It was possible to send incomplete list of replies.
2395 Fixed the WHOIS and IDENTIFY to send the request to router
2396 if normal server did not do it and did not find any results.
2398 Affected file silcd/command.c.
2400 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2402 * Moved the internal data from SilcClient context into its
2403 own file, not accesible to application. Affected files
2404 lib/silcclient/client.h and lib/silcclient/client_internal.h,
2405 and other files in client library.
2407 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2409 * Added doc/examples installation target in Makefile.am.pre.
2412 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2414 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
2415 commands the found client entry will be removed from the
2416 cache, after notifying application about the error. Affected
2417 file lib/silcclient/command_reply.c.
2419 * Changed the /MSG to check for exact nickname user gave, and
2420 not let `nick' match `nick@host' if it is only one found. Now,
2421 user must type the exact nickname (like nick@host2) even if
2422 there are no more than one same nicks found. This is to avoid
2423 a possibility of sending nickname to wrong nickname since
2424 `nick' could match `nick@host'. Affected file is
2425 irssi/src/core/silc-servers.c.
2427 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2429 * Do not print "you are now server operator" or similar when
2430 giving /away command. Affected files are
2431 irssi/src/silc/core/client_ops.c, silc-servers.h.
2433 * Made the silc_server_command_pending_error_check to send
2434 the same command reply payload it received back to the
2435 original sender of the command. This way all arguments
2436 that was received by the server will be received by the
2437 client too. Affected file silcd/command.c.
2439 * Added the silc_idcache_add to return the created cache entry
2440 to a pointer. Affected file lib/silccore/silcidcache.[ch].
2442 * Add global clients to expire if they are not on any channel.
2443 This is because normal server will never know if they signoff
2444 if they are not on any channel. The cache expiry will take
2445 case of these entries. This is done by normal servers only.
2446 The affected files are silcd/command_reply.c,
2447 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
2449 * If server receives invalid ID notification for WHOIS or
2450 IDENTIFY and the ID exists in the lists, it is removed.
2451 Affected file silcd/command_reply.c.
2453 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
2454 in client then client entry that it matches is searched and
2455 the nickname is printed on the screen for user. Affected
2456 file irssi/src/silc/core/client_ops.c.
2458 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2460 * Use cache entry expire time in the LIST command reply to
2461 purge old entries from the cache after the LIST command
2462 reply has been received. This way we don't have non-existent
2463 entries in the cache for too long. Affected file is
2464 silcd/command_reply.c.
2466 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2468 * If we are normal server, and we've not resolved client info
2469 in WHOIS or IDENTIFY from router, and it is global client,
2470 we'll check whether it is on some channel. If it is not
2471 then we cannot be sure about its validity and will resolve it
2472 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
2473 file silcd/command.c.
2475 * Search channel by name (if possible) rather than by ID
2476 in IDENTIFY command's command reply. Affected file is
2477 silcd/command_reply.c.
2479 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2481 * Distribute to the channel passphrase in CMODE_CHANGE notify.
2482 Updated specs and implemented it. Affected file silcd/command.c,
2483 silcd/packet_send.c and silcd/packet_receive.c.
2485 * Implemented the <founder auth> payload handling in the JOIN
2486 command. If provided all conditions for channel joining
2487 except requirement to provide correct passphrase can be
2488 overrided by the channel founder. Updated the protocol specs.
2489 Affected file silcd/command.c.
2491 Added support for founder auth in JOIN command in client
2492 library. Fixed the parsing of the JOIN command now to support
2493 all options as they should be. The affected file is
2494 lib/silcclient/command.c.
2496 * Optimized the WHOIS and IDENTIFY commands to send the request
2497 to router only if it includes nicknames or other names. If
2498 they include only IDs then check the local cache first before
2499 routing. Affected file is silcd/command.c.
2501 * Added channels topic announcements. Affected file is
2502 silcd/packet_receive.c and silcd/server.c.
2504 * Fixed the silc_server_send_notify_topic_set to really destine
2505 the packet to channel. Affected file silcd/packet_send.c.
2507 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
2508 library. Affected file lib/silcclient/client_notify.c.
2510 * Added UMODE announcements. Affected file silcd/server.c.
2512 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2514 * Memory leak fixes in:
2516 lib/silcutil/silcsockconn.c
2517 lib/silcske/silcske.c
2518 lib/silcske/groups.c
2520 lib/silccrypt/silcpkcs.c
2521 lib/silccore/silccommand.c
2522 lib/silccore/silcidcache.c
2527 * ROBOdoc documented the lib/silcske/groups.h file and a
2528 bit changed the interface for better.
2530 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2532 * Update the client entry context in the ID cache after
2533 nick change. Affected file lib/silcclient/command.c.
2534 Fixes the CUMODE command when regaining founder privileges,
2535 and a little WHOIS problem.
2537 * Fixed silc_net_gethostbyname to correctly call the
2538 inet_ntop. Affected file lib/silcutil/silcnet.c.
2540 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2542 * Added IPv6 support checking to the configure.in.pre, added
2543 also --enable-ipv6 option to override the check. Affected
2544 file configure.in.pre.
2546 * The silc_thread_create now calls the start function
2547 directly if threads support is not compiled in. Removes
2548 ugly #ifdef's from generic code. Affected files are
2549 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
2551 * Added silc_net_gethostby[name/addr]_async to asynchronously
2552 resolve. Affected files are lib/silcutil/silcnet.[ch].
2554 * Added support for rendering IPv6 based server, client and
2555 channel IDs. Affected file lib/silcutil/silcutil.c.
2557 * Added support for creating IPv6 based server IDs. Affected
2558 file is silcd/serverid.c.
2560 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2562 * Added silc_net_gethostby[addr/name] into the
2563 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
2564 routines. Added silc_net_is_ip[4/6]. Affected file is
2565 lib/silcutil/unix/silcunixnet.c. All routines that take
2566 address as argument now supports both IPv4 and IPv6 addresses.
2568 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2570 * Fixed LIST command reply sending in server. Affected file
2573 * Server now sends the kicker's client ID in the KICK notify
2574 to the kicked client. Affected file silcd/command.c.
2576 * The client library now parses the kickers client ID and
2577 UI displays it. Affected files lib/silcclient/client_notify.c
2578 and irssi/src/silc/core/silc-channels.c, module-formats.c.
2580 * Made all payload parsing function prototypes consistent.
2581 They all take now const unsigned char * and uint32 pair as
2582 the payload data instead of SilcBuffer. Changes all around
2583 the source tree. Other unsigned char* -> const unsigned char*
2584 changes around the tree as well.
2586 * Optimized SFTP client and server packet sending not to
2587 allocate new buffer for each packet but to recycle the
2588 first allocated buffer. Affected files are
2589 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
2591 * Optimized the SFTP client to use SilcList instead of
2592 SilcDList for requests, because it is faster. Affected file
2593 is lib/silcsftp/sftp_client.c.
2595 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
2596 into lib/silccore/silcid.[ch].
2598 Renamed silcpayload.[ch] into silcargument.[ch].
2600 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2602 * If client entry is deleted with active key agreement
2603 session, abort the session.
2605 The silc_client_abort_key_agreement now calls the completion
2606 callback with new SILC_KEY_AGREEMENT_ABORTED status.
2608 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
2611 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2613 * Don't use __restrict in older GCC's. Affected file is
2614 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
2616 * silc_net_localhost now attempts to reverse lookup the
2617 IP/hostname. Affected file lib/silcutil/silcnet.c.
2619 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
2620 command. It can be used to gain founder privileges at
2621 the same time when joining the channel.
2623 Defined that the SILC_NOTIFY_TYPE_KICKED send the
2624 kicker's client ID as well. Updated protocol specs.
2626 Defined that the server must send SILC_COMMAND_IDENTIFY
2627 command reply with error status to client who sent
2628 private message with invalid client ID.
2630 Updated the protocol specification.
2632 * Added silc_server_send_command_reply to send any
2633 command reply. Affected file silcd/packet_send.[ch].
2635 * Added silc_id_payload_encode_data to encode ID payload
2636 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
2638 * The server now send IDENTIFY command reply with error
2639 status if client ID in private message is invalid. Affected
2640 file silcd/packet_receive.c.
2642 * Save the server key file with server's IP address in
2643 the filename instead of hostname. The affected file is
2644 irssi/src/silc/core/client_ops.c.
2646 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2648 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
2651 * Added libtool support for compiling shared objects in
2652 lib/silcsim. Affected file configure.in.pre and
2653 lib/silcsim/Makefile.am. Original patch by cras.
2655 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2657 * Pid file configuration, and server's config file fixes
2658 patch by toma. Updated CREDITS file.
2660 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2662 * Fixed silc_client_channel_message to not try to decrypt
2663 the message twice if it resolved the destination client
2664 information. This could cause of dropping one channel
2665 message. Affected file lib/silcclient/client_channel.c.
2667 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2669 * Added silc_client_run_one into lib/silcclient/silcapi.h and
2670 lib/silcclient/client.c. This function is used when the SILC
2671 Client is run under some other scheduler, or event loop or
2672 main loop. On GUI applications, for example this may be
2673 desired to used to run the client under the GUI application's
2674 main loop. Typically the GUI application would register an
2675 idle task that calls this function multiple times in a second
2676 to quickly process the SILC specific data.
2678 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2680 * Fixed silc_server_drop() for dropping the supplementary
2681 groups as well, this could cause a security hole on some
2684 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2686 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
2689 * Write PID file after dropping privileges. Added -F option
2690 to run server on foreground. A patch by debolaz.
2691 Affected files silcd/server.c, silcd/silcd.c.
2693 * Fixed MOTD to return the MOTD file server name. Affected
2694 file silcd/command.c.
2696 * Added INFO command reply handling to the Irssi SILC Client.
2697 Affected file irssi/src/silc/core/client_ops.c.
2699 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2701 * Fixed the silc_idcache_list_* routines to really support
2702 the dynamic list. Fixes a crash. Affected file is
2703 lib/silccore/silcidcache.c.
2705 * Fixed the LIST command reply to really call LIST command's
2706 pending callbacks. Affected file silcd/command_reply.c.
2708 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2710 * Update conn->local_entry->nickname after giving NICK
2711 command. Affected file lib/silcclient/command.c.
2713 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
2715 * Added the [pid] option to the silcd configuration file
2717 Affected files: serverconfig.[ch] and silcd.c
2719 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2721 * Save fingerprint in WHOIS command reply in server.
2722 Affected file silcd/command_reply.c.
2724 * Fixed NICK commands pending callback registration.
2725 Affected file lib/silcclient/command.c.
2727 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2729 * Use ++server->cmd_ident when sending commands in server,
2730 instead of random number. Affected file silcd/command.c.
2732 * Fixed GETKEY command reply to call actually GETKEY pending
2733 command callbacks. Affected file silcd/command_reply.c.
2735 * A bit stricter check for nicknames. Check for same nickname
2736 in NICK command also. Affected file silcd/command.c.
2738 * Do not call INFO command everytime client ID changes, only
2739 during first connecting. Affected file lib/silcclient/client.c.
2741 * Set the new nickname only after successful command reply for
2742 NICK command is returned by server. Affected file
2743 lib/silcclient/command.c.
2745 * Remove nicknames from nicklist during server_signoff notify.
2746 Should fix /NAMES bit more. The affected file is
2747 irssi/src/silc/core/silc-channels.c.
2749 * Added `fingerprint' field to the SilcIDListData in the
2750 silcd/idlist.h to hold the fingerprint of the client's
2753 Send the fingerprint of the client's public key in WHOIS
2756 Affected files silcd/command.c, and silcd/idlist.[ch].
2758 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
2759 create fingerprint from given data.
2761 * Show the fingerprint of the client's public key in WHOIS.
2762 Affected files irssi/src/module-formats.[ch] and
2763 irssi/src/silc/core/client_ops.c.
2765 * Format the multiple same nicknames also during JOIN and
2766 NICK_CHANGE notifys. Affected file is
2767 lib/silcclient/client_notify.c.
2769 * Do not print error on screen for invalid private message
2770 payload since it can come if someone is sending private
2771 messages with wrong key. Affected file
2772 lib/silccore/silcprivate.c.
2774 * Fixed multiple concurrent /PING crash. Affected file
2775 lib/silcclient/command.c.
2777 * Changed the wrong ID encoding. All IP addresses must be
2778 in MSB first order in encoded format. They were encoded
2779 wrong and was in LSB format. Affected files are
2780 silcd/serverid.c, lib/silcutil/silcutil.c.
2782 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
2784 * Call the `connect' client operation through the scheduler
2785 in case of error. Affected file lib/silcclient/client.c.
2787 * Call the `failure' client operation even if the error
2788 occurred locally during a protocol. Affected file is
2789 lib/silcclient/protocol.c.
2791 * Added support of sending LIST command to router from normal
2792 server. This way normal server can get list of all channels
2793 in the network too. Fixed the channel list sending in the
2794 server too. Affected files are silcd/command.c, and
2795 silcd/command_reply.[ch].
2797 * Added silc_server_update_channels_by_server and
2798 silc_server_remove_channels_by_server. They are used during
2799 disconnection of primary router and in backup router protocol.
2800 Affected file silcd/server_util.[ch], silcd/server.c and
2801 silcd/server_backup.c.
2803 * Fixed channel adding to global list in IDENTIFY command
2804 reply in server. Affected file silcd/command_reply.c.
2806 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2808 * If the incoming packet type is REKEY or REKEY_DONE process
2809 that packet always synchronously. Fixes yet another MAC
2810 failed error on slow (dialup) connections. Affected file
2811 lib/silcclient/client.c and silcd/server.c.
2813 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2815 * Call check_version SKE callback for initiator too. Affected
2816 file lib/silcske/silcske.c.
2818 * Implemented fix for security hole found in the SKE that was
2819 fixed in the specification few days back; the initiator's
2820 public key is now added to the HASH value computation.
2821 Added backwards support for the old way of doing it too, for
2822 old clients and old servers. Affected file is
2823 lib/silcske/silcske.c.
2825 * Enabled mutual authentication by default in SKE. If initiator
2826 is not providing mutual authentication the responder will
2827 force it. This will provide the proof of posession of the
2828 private key for responder. The affected files are
2829 lib/silcclient/protocol.c and silcd/protocol.c.
2831 * Do not cache anymore the server's public key during SKE.
2832 We do mutual authentication so the proof of posession of
2833 private key is done, and if the server is authenticated in
2834 conn auth protocol with public key we must have the public
2835 key already. Affected file silcd/protocol.c.
2837 * Added new global debug variable: silc_debug_hexdump. If
2838 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
2839 file lib/silcutil/silclog.[ch].
2841 * Fixed compilation warning due to char * -> const char *.
2842 Affected files lib/silcutil/silcnet.h, and
2843 lib/silccore/silcauth.[ch].
2845 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2847 * Fixed CMODE command when new channel key was created. If
2848 the creation failed the old key was removed. Next time giving
2849 same command would crash the server since the old key was
2850 freed already. Affected file silcd/command.c.
2852 * Fixed the silc_server_announce_get_channels to not crash
2853 on reconnect. Affected file silcd/server.c.
2855 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2857 * Added silc_log_set_debug_string function to set a regex
2858 string to match for debug output. Only the function names,
2859 or filenames matching the given debug string is actually
2860 printed. This way it is possible to filter out those debug
2861 strings that user is not interested in.
2863 Fixed a bug in silc_string_regexify.
2865 Affected files lib/silcutil/silclog.[ch], and
2866 lib/silcutil/unix/silcunixutil.c.
2868 * Changed the -d options in both server and Irssi SILC client
2869 to take the debug string as argument. Affected files
2870 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
2872 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2874 * Added silc_hash_babbleprint to create a Bubble Babble
2875 Encoded fingerprint. The encoding is developed by Antti
2876 Huima (draft-huima-babble-01.txt), and it creates human
2877 readable strings out of binary data. Affected file
2878 lib/silccrypt/silchash.[ch].
2880 * Print the babble print now in addition of fingerprint as well
2881 in Irssi SILC client. Affected files are
2882 irssi/src/fe-common/silc/module-formats.[ch],
2883 irssi/src/fe-common/silc/core/client_ops.c.
2885 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2887 * Fixed a security problem found in SKE. The initiator's
2888 public key too is now added to the HASH hash value creation
2889 which is signed by the responder to create the SIGN value.
2890 This will prevent anyone in the middle to lie to the responder
2891 about the initiator's public key. If this is done now, the
2892 man in the middle will get caught. Updated the protocol
2895 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2897 * Better installation directory handling. Configure module
2898 paths and other paths automatically to example_silc* files
2899 in doc/. A patch by toma.
2901 * Fixed compiler warning from MPI library, and from SILC RNG.
2904 * Added SILC_SERVER_PID_FILE to define the pid file for server.
2905 It can be configured with ./configure. A patch by toma.
2907 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2909 * Find correct make to use in prepare-clean. A patch by
2910 toma. Affected file prepare-clean.
2912 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
2914 * Added irssi variables use_auto_addr, auto_bind_ip,
2915 auto_bind_port and auto_public_ip.
2917 * Changed the interface for silc_client_send_key_agreement
2918 in lib/silcclient/silcapi.h
2922 irssi/src/silc/core/silc-core.c
2924 lib/silcclient/silcapi.h
2925 irssi/src/silc/core/silc-channels.c
2926 lib/silcclient/client_keyagr.c
2929 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2931 * Added silc_pkcs_public_key_compare to compare two
2932 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
2934 * Check that the client who set the founder mode on the
2935 channel is the same client that is giving the founder
2936 mode to itself. It is done by comparing the saved public
2937 key (it is saved even in the authentication is passphrase).
2938 Affected file silcd/command.c.
2940 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2942 * Do not process packet for disconnected socket connection.
2943 Affected file lib/silccore/silcpacket.c.
2945 * Process the DISCONNECT packet through scheduler in the
2946 client library. Affected file lib/silcclient/client.c.
2948 * Fixed the silc_client_packet_parse to not to increase
2949 the packet sequence number if the conn->sock and the
2950 current socket connection is not same. This can happen
2951 for example during key agreement when the conn includes
2952 multiple socket connections (listeners). Affected file
2953 lib/silcclient/client.c.
2955 * The sender of the file transfer request now provides also
2956 the pointer (listener) for the key exchange protocol. If
2957 the listener cannot be created then it sends empty key
2958 agreement and lets the receiver provide the listener.
2960 Added `local_ip' and `local_port' arguments to the
2961 silc_client_file_send. If they are provided they are used,
2962 if not then it will attempt to find local IP address, if
2963 not found or bind fails then the remote client will provide
2966 Affected files are lib/silcclient/client_ftp.c and
2967 lib/silcclient/silcapi.h.
2969 * Extended the FILE SEND command to support defining the
2970 local IP and port for key exchange listener. They are
2971 optional. Affected file irssi/src/silc/core/silc-servers.c.
2973 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2975 * Defined to WHOIS command reply the sending of fingerprint
2976 of the client's public key (if the proof of posession of the
2977 corresponding private key is verified by the server).
2978 Updated to the protocol specification.
2980 * Added support of receiving the client's public key's
2981 fingerprint in command reply in client library. Affected
2982 file is lib/silcclient/command_reply.c, and
2983 lib/silcclient/idlist.[ch].
2985 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2987 * Do not send over 128 chars long nickname to the server
2988 in NICK command. Affected file lib/silcclient/command.c.
2990 * Do not send over 256 chars long channel names to the server
2991 in JOIN command. Affected file lib/silcclient/command.c.
2993 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2995 * Assure that silc_server_close_connection cannot be called
2996 twice for same socket context. Affected file is
2999 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3001 * Send error message to application if opening file for
3002 writing during file transfer fails. Affected file is
3003 lib/silcclient/client_ftp.c.
3005 Remove all file transfer sessions for a client that we're
3006 removing from ID cache.
3008 Affected file is lib/silcclient/client_ftp.c.
3010 * Fixed silc_net_addr2bin to return correct address. Affected
3011 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3013 * Fixed file transfer session removing on signoff notify.
3014 Affected file irssi/src/silc/core/silc-servers.c.
3016 * Added the SilcClientFileError to be returned in the monitor
3017 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
3018 Affected file lib/silcclient/silcapi.h.
3020 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3022 * Fixed a crash in silc_client_ftp_free_sessions and
3023 silc_client_ftp_session_free_client. Affected file
3024 lib/silcclient/client_ftp.c.
3026 * Added `disabled' field in the SilcChannelEntry in the server
3027 to indicate if the server entry is disabled. Affected file
3028 silcd/idlist.h, silcd/command[_reply].c.
3030 * SILC server adds now /var/run/silcd.pid everytime it is
3031 started. Affected file silcd/silcd.c.
3033 * Added silc_server_packet_send_clients to send a packet to
3034 the provided table of client entries. Affected file
3035 silcd/packet_send.[ch].
3037 * Fixed a crash in client resolving in client_prvmsg.c in
3038 client library. Affected file lib/silcclient/client_prvmsg.c.
3040 * Do not actually remove the client directly from ID cache
3041 during SERVER_SIGNOFF, but invalidate it. This way we
3042 preserve the WHOWAS info for the client. Affected file
3043 silcd/server_util.c.
3045 * Fixed SERVER_SIGNOFF notify handling in the server. The
3046 server is now able to process incoming SERVER_SIGNOFF notify
3047 for a server that it doesn't even know about. It will remove
3048 the clients provided in the notify. Affected file
3049 silcd/packet_receive.c.
3051 * Check for partial packet in data queue after every packet that
3052 was found from the queue. Return and wait for more data if
3053 there is partial data in queue. Affected file is
3054 lib/silccore/silcpacket.c.
3056 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3058 * Added SilcClietFileError enum to indicate error in
3059 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
3060 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
3061 Affected files lib/silcclient/silcapi.h and
3062 lib/silcclient/client_ftp.c.
3064 * Check that newsize in silc_buffer_realloc is larger than
3065 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
3067 * Added better monitor of file transfers. It now monitors
3068 key agreement protocol during the file transfer too. Added
3069 error reporting too. Affected files
3070 irssi/src/silc/core/silc-servers.c,
3071 irssi/src/fe-common/silc/module-formats.[ch].
3073 * Wrote a help file for FILE command.
3075 * Added silc_rng_global_get_byte_fast to get not-so-secure
3076 random data as fast as possible. Random data is read from
3077 /dev/urandom if available and from the SILC RNG if not
3078 available. It is used in padding generation. Affected file
3079 lib/silccrypt/silcrng.[ch].
3081 * All packets in client library are now processed synchronously.
3082 Optimized packet processing a lot. Affected file
3083 lib/silcclient/client.c.
3085 * All server connection packets are processing synchronously
3086 now in server, to optimize packet processing. Affected file
3089 * Include files are installed now only in Toolkit distribution
3090 if make install is given. Affected files: all Makefile.am's.
3092 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3094 * Assure that silc_client_notify_by_server_resolve does not
3095 resolve the client information multiple times. If it cannot
3096 be found by the first it cannot be found at all. Affected
3097 file lib/silcclient/client_notify.c.
3099 * Fixed WHOWAS command reply calling. Affected file
3100 lib/silcclient/command_reply.c.
3102 * Removed all references to silc_idlist_get_client from the
3103 Irssi SILC client since that call is internal call used by
3104 the library. The Irssi SILC client will use now client
3105 retrieval functions found in silcapi.h.
3107 * Fixed a bug in resolving nickname info before sending
3108 private message. It used freed memory. Affected file
3109 irssi/src/silc/core/silc-servers.c.
3111 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3113 * Assure my_channels statistics cannot go negative in server.
3114 Affected files silcd/server.c, silcd/server_util.c.
3116 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3118 * Upgraded dotconf 1.0.2 to 1.0.6 in lib/dotconf.
3120 Tue Oct 23 13:51:19 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3122 * Win32 Toolkit changes. Affected files
3123 win32/silc.dsw, win32/libsilc/libsilc.def,
3124 win32/libsilcclient/libsilc.def,
3125 lib/silcutil/silcutil.c, and
3126 lib/sftp/sftp_fs_memory.c.
3128 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3130 * Added silc_net_localip to return local host's IP address.
3131 Affected file lib/silcutil/silcnet.[ch].
3133 * If key exchange or rekey protocol is active for a connection
3134 parse all packets syncronously since there might be packets
3135 in packet queue that we are not able to process without first
3136 processing packets before them. Affected file silcd/server,
3137 lib/silcclient/client.c.
3139 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
3140 whether library should continue processing the packet.
3141 Affected file lib/silccore/silcpacket.h.

3172 lib/silcutil/silcutil.[ch].
3174 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3176 * Resolve the client info when received private message or
3177 channel message for a client which nickname we don't know.
3178 Affected files lib/silcclient/client_prvmsg.c and
3179 lib/silcclient/client_channel.c.
3181 * Do not crash in /KEY if client is not connected. Affected
3182 file irssi/src/silc/core/silc-channels.c.
3184 * Added SilcClientStatus field to the SilcClientEntry in the
3185 lib/silcclient/idlist.h.
3187 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
3188 is incomplete and is being resolved, it won't be resolved
3191 Make sure also that USERS command reply does not resolve
3192 twice information. Affected file is
3193 lib/silcclient/command_reply.c.
3195 Make sure that silc_client_get_clients_by_list does not
3196 resolve twice same information.
3198 * Check for valid client->id in the silc_server_free_client_data.
3199 Affected file silcd/server.c.
3201 * Fixed /GETKEY nick@server not to crash if the server entry
3202 is not found. Affected file lib/silcclient/command.c.
3204 * Fixed the silc_server_check_cmode_rights to check the
3205 requested modes correctly. Affected file silcd/command.c.
3207 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3209 * Better checks for non-printable chars in nick added.
3210 Affected file silcd/command.c.
3212 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3214 * Call the silc_server_udpate_servers_by_server in the
3215 primary router that comes back online in the backup resuming
3216 protocol. Otherwise it routes packets wrong. Affected file
3217 silcd/server_util.[ch], silcd/server_backup.c.
3219 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3221 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
3222 lib/silcutil/silcbuffmt.[ch].
3224 * Redefined the SILC packet header to include the padding
3225 length. Affected file lib/silccore/silcpacket.[ch].
3227 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
3228 length for maximum padding up to 128 bytes). Affected
3229 file lib/silccore/silcpacket.h.
3231 * Removed all backwards support for old 0.5.x MAC thingies.
3232 The SILC packet header change makes it impossible to be
3233 backwards compatible.
3235 * Send the ENDING packet with timeout in the backup resuming
3236 protocol. This is to assure that all routers has connected
3237 to the primary router. Affected file silcd/server_backup.c.
3239 * Changed the RNG to take the first IV from random data. It
3240 used to take it from zero actually. Changed the RNG also
3241 to use /dev/urandom during session. /dev/random is used
3242 in initialization. Affected file lib/silccrypt/silcrng.[ch].
3244 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3246 * Changed the SILC packet header to have the first two bytes
3247 (the packet length) encrypted. Affected files aroung the
3248 code tree, lib/silccore/silcpacket.[ch]. Removed the
3249 SilcPacketCheckDecrypt callback. It is not needed anymore
3250 since the silc_packet_receive_process will determine now
3251 whether the packet is normal or special.
3253 * Implemented the unidirectional MAC keys. Affected files
3254 lib/silcske/silcske.c, silcd/protocol.c and
3255 lib/silcclient/protocol.c.
3257 * Implemented the packet sequence number to the MAC computation.
3258 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
3259 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
3260 lib/silcclient/protocol.c.
3262 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3264 * Allow backup router to announce servers. All servers
3265 announced by backup router are added to the global list
3266 automatically. Update hte server's socket to our primary
3267 router also when backup router announces a server.
3268 Affected file silcd/packet_receive.c.
3270 * Do not update the client->router in the function
3271 silc_server_udpate_clients_by_server if the client is on
3272 global list. We might fail to find any specific server
3273 for locally connected clients and local cell clients. They
3274 should still use the `from' and not `to' as client->router.
3275 This fixes backup router resuming protocol. Affected file
3276 silcd/server_util.c.
3278 * Decrease channel statistics count only if the channel
3279 deletion worked. Affected files are silcd/server.c and
3280 silcd/server_util.c.
3282 * Added silc_server_update_servers_by_server to update origin
3283 of all server entries. Used during backup router protocol.
3284 Affected files silcd/server_util.[ch], silcd/server.c. and
3285 silcd/backup_router.c.
3287 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
3288 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
3289 silc_hmac_get_hash and silc_hmac_get_name. Affected file
3290 lib/silccrypt/silchmac.c.
3292 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3294 * Assure that router cannot reroute the same channel message
3295 to the sender. Affected file silcd/packet_receive.c.
3297 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3299 * Made better checks that the channel message is not sent
3300 to the router it came from. Affected file is
3301 silcd/packet_send.c. Fixed memory leak too.
3303 * Announce informations for incoming router connection, but
3304 only after checking if it is replaced by backup router.
3305 Affected file silcd/packet_receive.c.
3307 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3309 * Fixed the backup resuming protocol to work in multiple
3310 router environment. Affected file silcd/server_backup.c.
3312 * Route packet only to one router in the function
3313 silc_server_packet_send_to_channel. Affected file is
3314 silcd/packet_send.c.
3316 * Fixed silc_server_send_notify_dest to set the broadcast
3317 flag. Fixed the silc_server_send_notify_topic to actually
3318 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
3319 Affected file silcd/packet_send.c.
3321 * Changed the SFTP Filesystem interface. Changed the
3322 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
3323 the filesystem operation function. The SilcSFTPFilesystem
3324 is now a context that is allocated by all filesystem allocation
3325 functions and it already includes the operations structure
3326 and filesystem specific context. It is given as argument
3327 now to the silc_sftp_server_start. This made the interface
3328 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
3329 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
3331 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3333 * Changed the backup router adding and getting interfaces
3334 in the server. The router that will be replaced by the
3335 specified backup router is now sent as argument. Affected
3336 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
3339 * Added silc_net_addr2bin_ne to return the binary form of
3340 the IP address in network byte order. Affected files
3341 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
3343 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3345 * Check for existing server ID in silc_server_new_server
3346 and in silc_server_connect_to_router_final and remove the
3347 old entry if it exists. Affected file silcd/packet_receive.c,
3350 * Send the channel message always to only one router, either
3351 in upstream or downstream. Affected file is
3352 silcd/packet_send.c.
3354 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3356 * Wrote the definition of the backup resuming protocol to the
3357 protocol specification.
3359 * Removed one redundant channel key generation from normal
3360 server during joining procedure. Removed one redundant
3361 channel key sending from server to router during joining
3362 procedure. Affected file silcd/command.c.
3364 * Made minor bugfixes to the backup router resuming protocol.
3365 Affected file silcd/server_backup.c, server.c.
3367 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3369 * Added --disable-asm configuration option. Affected files
3370 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
3373 * Implemented the backup resuming protocol that is used to
3374 resume the primary router position in the cell after the
3375 primary router comes back online. Affected files
3376 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
3377 and silcd/server_util.[ch].
3379 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3381 * Sleep two (2) seconds after sending QUIT command to server.
3382 Affected file lib/silcclient/command.c.
3384 * Assure that if outgoing data buffer is pending do not force
3385 send any data. Affected file silcd/packet_send.c.
3387 * Assure that if outgoing data buffer is pending do not force
3388 send any data. Affected file lib/silcclient/client.c.
3390 * Implemented the backup router support when the primary router
3391 goes down. The servers and routers can now use the backup
3392 router as new primary router without loosing connectivity.
3394 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3396 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
3397 in the server to indicate disabled entry. All data read
3398 from the connection will be ignored and no data is sent
3399 for entry that is disabled. Affected files are
3400 silcd/idlist.h, silcd/server.c.
3402 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3404 * Created SFTP client and server test programs in the
3405 lib/silcsftp/tests directory.
3407 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3409 * Implemented memory filesystem (virtual filesystem) for
3410 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
3413 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3415 * Implemented the SFTP (SSH File Transfer Protocol) to the
3416 lib/silcsftp. It includes SFTP client and SFTP server
3419 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3421 * Moved lib/silccore/silcprotocol.[ch] to the
3422 lib/silcutil library.
3424 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
3425 take variable argument list pointer as argument. Affected
3426 file lib/silcutil/silcbuffmt.[ch].
3428 * Added silc_buffer_set function that is used to set data
3429 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
3430 Affected file lib/silcutil/silcbuffer.h.
3432 * Changed various routines in the core library to use the new
3433 silc_buffer_set instead of allocating new buffer only for
3436 * Added 64-bit value formatting and unformatting support to the
3437 silc_buffer_[un]format routines. Affected file is
3438 lib/silcutil/silcbuffmt.[ch].
3440 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
3441 to includes/bitmove.h.
3443 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3445 * Fixed channel user mode saving in client library. Affected
3446 file lib/silcclient/command[_reply].c.
3448 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3450 * Defined the file transfer to the SILC Protocol. Added
3451 new packet type SILC_PACKET_FTP and defined File Transfer
3452 Payload. The mandatory file transfer protocol is SFTP
3453 (SSH File Transfer Protocol). Affected file in addition
3454 of the internet draft is lib/silccore/silcpacket.h.
3456 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
3457 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
3458 is used as part of backup router protocol when the primary
3459 router of the cell is back online and wishes to resume
3460 the position as primary router.
3462 * Redefined the MAC generation keys in the protocol. The
3463 same key is not used anymore in both direction. Both
3464 direction will now use different keys for sending and
3465 receiving. This fixes a potential security flaw. This
3466 change causes incompatibilities in the protocol.
3468 * Redefined also the MAC computation from the packet.
3469 An packet sequence number is now added to the MAC
3470 computation. This prevents possible replay attacks against
3471 the protocol. This change too causes incompatibilities
3474 Added `sequence' field to the SilcPacketContext to hold
3475 the current sequence number for the packet.
3477 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3479 * Added `created' field to the SilcIDListData in the file
3480 silcd/idlist.h to indicate the time when the entry was
3483 * Added `created' field to the SilcChannelEntry too. Affected
3484 file silcd/idlist.h.
3486 * Added `creation_time' aguments to all the announcement functions
3487 in the server. If it is provided then only the entries that
3488 was created after the provided time frame are actually
3489 announced. Affected file silcd/server.[ch].
3491 * The protocol says that the Channel ID's IP address must be
3492 based on the router's IP address. Added check for this in
3493 the silc_server_new_channel when processing incoming New Channel
3494 Payload. Affected file silcd/packet_receive.c.
3496 * Print out the correct version with --version in SILC client.
3497 Affected file irssi/src/silc/core/silc-core.c.
3499 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3501 * Fixed WHOWAS command to check for completnes of the client
3502 entry always, not just when the command is coming from client.
3503 Affected file silcd/command.c.
3505 * Added new function silc_server_packet_queue_purge to purge the
3506 outgoing data queue to the network. After the function returns
3507 it is guaranteed that the outgoing packet queue is empty.
3508 Affected file silcd/packet_send.[ch].
3510 * Purge the outgoing packet queue in the rekey protocol's final
3511 callback to assure that all rekey packets go to the network
3512 before quitting the protocol. Affected file silcd/server.c.
3514 * Added silc_client_packet_queue_parse as similar function as
3515 in server to the client library. The affected file is
3516 lib/silcclient/client.c.
3518 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3520 * Splitted silcd/server.c and created silcd/server_util.[ch]
3521 for utility functions.
3523 * Added new socket flag SILC_SF_DISABLED to indicate that the
3524 connection is open but nothing can be sent to or received from
3525 the connection. Affected file lib/silcutil/silsockconn.[ch].
3526 The checking for disabled socket is checked in the low level
3527 silc_socket_write and silc_socket_read functions.
3529 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3531 * Allow only nicknames and channel names that fits into the
3532 7-bit unsigned char ASCII set. Affected file silcd/command.c.
3534 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3536 * When processing JOIN command reply in server check that if
3537 the channel exists in our global list we'll move it the local
3538 list. Affected file silcd/command_reply.c.
3540 * Fixed the check whether client is joined on the channel already
3541 in JOIN command. Affected file lib/silcclient/command.c.
3543 * Fixed the JOIN command reply to check whether the channel
3544 already exists. Affected file lib/silcclient/command_reply.c.
3546 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3548 * Added silc_ske_status_string to map the SKE error numbers
3549 to readable strings. The affected files are
3550 lib/silcske/silcske[_status].[ch].
3552 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3554 * Do not show the private channels on the WHOIS channel list
3555 as it is not allowed by the protocol. The affected file is
3558 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3560 * Assure that the packet length digged from the actual packet
3561 is something sensible in the silc_packet_decrypt_rest_special
3562 in lib/silccrypt/silcpacket.c.
3564 * Free and NULL the allocated pointer in silc_hmac_alloc if
3565 the HMAC allocation fails. The affected file is
3566 lib/silccrypt/silchmac.c.
3568 * Print the selected security properties to the log files in
3569 the server. Affected file silcd/protocol.c.
3571 * Add SKE's reference counter even if calling the completion
3572 callback manually. Otherwise it goes negative, although it
3573 does not cause any problems. The affected file is
3574 lib/silcske/silcske.c.
3576 * Remove the client entry with short timeout after giving the
3577 KILL command. Affected file lib/silcclient/command.c.
3579 * Fixed to send error reply in WHOIS and IDENTIFY commands in
3580 case all found clients are already disconnected (WHOWAS would
3581 found them) in the server. Affected file silcd/command.c.
3583 * Update the last_receive (time of last data received) to be
3584 updated only when received private or channel message so that
3585 the idle time showed in WHOIS makes more sense.
3587 * Added boolean field `valid' in to the SilcClientEntry in the
3588 client library to indicate whether the entry is valid or not.
3589 This fixes the nickname change bug on channel when changing
3590 the nickname to be same than the old (like nick to Nick) the
3591 nickname formatter doesn't set the new nick anymore to Nick@host.
3592 Affected file lib/silcclient/idlist.[ch].
3594 * Now actually fixed the nickname changing on disconnection.
3595 Added new function silc_change_nick to the Irssi SILC Client.
3596 Affected file irssi/src/silc/core/client_ops.c,
3597 irssi/src/silc/core/silc-nicklist.[ch].
3599 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3601 * Check that the public key exists in the GETKEY command before
3602 trying to encode it. Affected file silcd/command.c.
3604 * Print some notifications on received public keys with GETKEY
3605 command in the Irssi SILC Client. Affected files are
3606 irssi/src/fe-common/silc/module-formats.[ch],
3607 irssi/src/silc/core/client_ops.c.
3609 * Use IDENTIFY command to resolve the server information in the
3610 GETKEY command instead of INFO command. Affected file
3611 lib/silcclient/command.c.
3613 * All command reply functions in the client library now calls
3614 the pending command reply callbacks even if an error has
3615 occurred. The server has done this a long time and now it was
3616 time to move the client library to this as well. Now all
3617 errors can be delivered back to the pending command reply
3618 callbacks if necessary. Affected files are
3619 lib/silcclient/command[_reply].[ch].
3621 * Change the nickname on disconnection back to the username
3622 because in reconnect the server will enforce it to it anyway.
3623 Affected file irssi/src/silc/core/silc-servers.c.
3625 * Fixed a config file parsing bug in the Irssi SILC client.
3626 Affected file irssi/src/silc/core/clientconfig.c.
3628 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3630 * When printing the channel mode on JOIN, verify that the
3631 channel key and channel's HMAC are valid. Affected file
3632 irssi/src/silc/core/client_ops.c.
3634 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3636 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
3637 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
3638 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
3640 * Removed channel key rekey task deleting from the function
3641 silc_server_save_channel_key. Affected file silcd/server.c.
3642 Added explicit timeout task context instead that is used to
3643 delete the task if we are registering a new task before the
3644 new task has elapsed.
3646 * When channel key rekey occurs the client library now saves
3647 the old channel key for a short period of time (10 seconds) and
3648 is able to use it in case some is still sending channel
3649 messages encrypted with the old key after the rekey. Affected
3650 file lib/silcclient/[idlist.h|client_channel.c].
3652 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3654 * Added check to the silc_server_new_id_real to not accept
3655 new ID if it is the sender's own ID. Affected file is
3656 silcd/packet_receive.c.
3658 * Assure that we do not announce ourself or the one we've
3659 sending our announcements when we're router and are announcing
3660 servers to our primary router. Affected file silcd/server.c.
3662 * Fixed silc_server_command_identify_check_client to assemble
3663 correct WHOIS packet. It send corrupted WHOIS packet and
3664 caused problem with router to router connections. Affected
3665 file silcd/command.c.
3667 Fixed also silc_server_command_whois_check the same way
3668 as for the IDENTIFY command.
3670 * Added new SilcIDListStatus to the server in the SilcIDListData
3671 structure. The status now includes the current status of
3672 the entry (like registered, resolved etc.). Affected file
3673 silcd/idlist.[ch]. Defined a bunch of different status types
3674 as well. This replaced the old boolean registered field as well.
3676 Added resolve_cmd_ident field to the SilcClientEntry structure
3677 too so that if the entry is for example being resolved so
3678 another command may attach to the same pending command reply
3679 without requiring to resolve the same entry again. This concept
3680 should optimize the WHOIS and the IDENTIFY resolving under
3681 heavy load by taking away unnecessary resolving for entries
3682 that are being resolved already.
3684 Added support for adding multiple pending commands for one
3685 command idenfier. Affected file silcd/command[_reply].[ch].
3687 * Fixed WHOIS and IDENTIFY save to remove the cache entry
3688 before deleting the data. Otherwise the hash table will have
3689 freed data in comparison functions. Affected file is
3690 silcd/command_reply.c.
3692 * Fixed silc_idlist_replace_client_id to add the new entry to
3693 the cache with NULL nickname. Otherwise there will be invalid
3694 memory as the nickname after the nickname is freed. Affected
3695 file silcd/packet_receive.c.
3697 * Fixed the silc_idlist_get_clients_by_hash. The entries was
3698 saved into wrong slots because the previous number of entries
3699 was not taken into account. Affected file silcd/idlist.c.
3700 Fixed same thing in silc_idlist_get_clients_by_nickname too.
3702 * If we are router and we receive JOIN notify to a channel that
3703 does not have any users then notified client is marked as the
3704 channel founder, as it is it. The affected file is
3705 silcd/packet_receive.c
3707 * Added to the extended hash table API's table_del_*ext functions
3708 the destructor as argument too, so that the caller can decide
3709 which destructor to use or whether to use destructor at all.
3710 Affected file lib/silcutil/silchashtable.[ch].
3712 * Fixed ID Cache purging. It actually deleted the entries from
3713 the hash table after the data was freed. The hash table ended
3714 up comparing freed memory. The affected file is
3715 lib/silccore/silcidcache.c.
3717 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3719 * Fixed Irssi SILC client's KILL command's HELP syntax.
3721 * The USERS command now resolves the detailed user information
3722 if the userinfo field is missing. Affected file is
3723 lib/silcclient/command_reply.c.
3725 * Do not print error in silc_file_read if the read file does
3726 not exist. Just silently return NULL. Affected file is
3727 lib/silcutil/silcutil.c.
3729 * Fixed the silc_log_output to not wine about NULL filename
3730 and to not create some bogus " " filename. Affected file is
3731 lib/silcutil/silclog.c.
3733 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3735 * Fixed various printing bugs on the user interface in the
3736 Irssi SILC Client. Minor changes that were forgotten from
3739 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3741 * Fixed the configure.in.pre and the compilation and distribution
3742 environment to support the new autoconf 2.52. That version is
3743 now required to compile the CVS trunk.
3745 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3747 * Renamed function silc_parse_nickname to silc_parse_userfqdn
3748 to generally parse user@fqdn format strings. Affected file
3749 lib/silcutil/silcutil.c.
3751 * Added nickname_format and nickname_force_format fields to the
3752 SilcClientParams structure. The first one defines the format
3753 for the nicknames that the library will enforce if the receives
3754 multiple same nicknames. The second one is boolean value and
3755 can be used to force the library to always enforce the format
3756 to the nicknames regardles whether there are multiple nicknames
3757 or not. This configurable formatting was employed to flexibly
3758 support accessing multiple nicknames from the user interface.
3759 The userinterface can now set the nicknames to what ever format
3760 they prefer. Affected file lib/silcclient/silcapi.h.
3762 Added function silc_client_nickname_format to the file
3763 lib/silcclient/idlist.c. It performs the nickname formatting.
3765 Added new field `hostname´ to the SilcClientEntry context.
3766 It holds the hostname of the client. Affected file is
3767 lib/silcclient/idlist.h.
3769 * Irssi SILC Client sets the nicknames in nick@hostn format.
3770 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
3771 irssi/src/silc/core/silc-core.c.
3773 The WHOIS printing now also shows both the real nickname and
3774 the formatted nickname so that user knows how to access the
3775 user if there are multiple same nicknames cached. Affected
3776 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
3777 printing formatting too to take the hostname now as a separate
3778 argument. The Affected file is
3779 irssi/src/fe-common/silc/modules-formats.[ch].
3781 * Changed the silc_client_get_clients_local to accept the formatted
3782 nickname as argument. It accepts the real nickname too but the
3783 formatted nickname can be used to find the true entry from
3784 multiple entries. Affected file lib/silcclient/silcapi.h and
3785 lib/silcclient/idlist.c.
3787 * Added nickname_format_parse field to the SilcClientParams.
3788 It is a callback function provided by the application to parse
3789 the nickname out of the formatted nickname string. The library
3790 calls it to get the nickname from the formatted string. Since
3791 the application generally knows better the format of the nickname
3792 string it parses it instead of the library, even though library
3793 encodes the formatted string. If the callback function is not
3794 provided then the library will use the string as is. The
3795 affected file is lib/silcclient/silcapi.h.
3797 * All the nickname strings passed to the client library in
3798 commands are now expected to be formatted nickname strings.
3799 If the command does not support the formatted nickname string
3800 it will assume that the sent string is the actual nickname.
3801 Affected file lib/silcclient/command.c.
3803 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3805 * Added public key authentication support to OPER and SILCOPER
3806 commands in the client library. Affected file is
3807 lib/silcclient/command.c.
3809 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3811 * Changed the get_auth_methdod client operation to be asynchronous.
3812 It can be async if the application resolves the authentication
3813 method from the server during the negotiation. Added new
3814 SilcGetAuthMeth completion callback that the application will
3815 call after resolving the authentication method.
3817 Added function silc_client_request_authentication_method that
3818 the application can use to resolve the authentication method
3819 from the server. Added also SilcConnectionAuthRequest callback
3820 that the library will call after the server has replied. The
3821 application can call this function if it does not know the
3822 current authentication method.
3824 Affected files are lib/silcclient/client.c and
3825 lib/silcclient/silcapi.h.
3827 * The Irssi SILC client now automatically resolves the authentication
3828 method incase any configuration information is not present (and
3829 currently there never is). The affected file is
3830 irssi/src/silc/core/client_ops.c.
3832 * Fixed public key authentication from the client library.
3833 Affected file lib/silcclient/protocol.c. Changed also the
3834 protocol specification about the public key authentication in
3835 the connection authentication protocol. The actual data to be
3836 signed is now computed with a hash function before signing.
3838 * Fixed the public key authentication from the server as well.
3839 Affected file silcd/protocol.c.
3841 * Removed the mlock()'s from the memory allocation routines.
3842 Affected file lib/silcutil/silcmemory.c. The ./configure does
3843 not check anymore for the mlock(). Affected file is
3846 * Fixed USERS command in server to allow the execution of the
3847 command for private and secret channels if the client sending
3848 the command is on the channel. Affected file silcd/command.c.
3850 * Fixed silc_client_get_clients_local to return the clients
3851 count correctly. It could return wrong value. Affected file
3852 lib/silcclient/idlist.c.
3854 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3856 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
3857 types. The assembler optimizations seemed not to like 64-bit
3858 data types. The assmebler optimizations thus are now enabled
3859 also for BSD systems as opposed to only enable them for Linux.
3861 * Do not check for threads at all on BSD systems. Affected
3862 file configure.in.pre.
3864 * Removed -n and -h options from the Irssi SILC Client since
3865 they are not used in silc.
3867 * Fixed the prime generation to assure that the first digit
3868 of the generated random number is not zero since our conversion
3869 routines does not like number strings that starts with zero
3870 digit. If zero digit is seen the random number is regenerated.
3871 This caused some corrupted RSA keys when the zero first digit
3872 was met. Affected file lib/silcmath/silcprimegen.c.
3874 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3876 * Fixed WIN32 configuration in the ./configure script.
3877 Fixed to include xti.h on environments that has it.
3878 Patches by Carsten Ilchmann and andrew.
3880 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3882 * Changed the silc_id_create_client_id to be collision
3883 resistant. It is now assured that there cannot be created
3884 two same client ID's. I suspect that some weird bugs in
3885 the server were actually caused by duplicate Client IDs.
3886 Affected file silcd/serverid.[ch]. A router receiving
3887 new ID now also assures and informs the sending server
3888 if the ID caused collision.
3890 * Changed the silc_id_create_channel_id to also assure that
3891 there are no collisions.
3893 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3895 * Statement about ignoring the Mutual Authentication flag when
3896 performing rekey with PFS was a bit misleading. It is ignored
3897 if it was set in the initial negotiation, it cannot be even
3898 set in the rekey. Fixed in the ke-auth draft. Started the
3899 new versions of the protocol drafts in the doc/.
3901 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3903 * Fixed a bug in silc_client_command_identify_save when saving
3904 new channel information. The channel name was no duplicated
3905 and caused crash on exit. Affected file is
3906 lib/silcclient/command_reply.c.
3908 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3910 * Fixed the getkey command handling in the server. Send just
3911 empty OK reply to the sender if the key could not be fetched
3912 (but everything else was ok, like the key just was not available).
3913 Changed the public key parameter to optional in the protocol
3914 specs so that empty OK reply can be sent. Affected file
3917 Added a message to Irssi SILC client to tell to user if the
3918 server did not return a public key.
3920 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3922 * Fixed a channel key regeneration bug. It registered new
3923 timeout tasks exponentially until all system resources were
3924 used. Affected file silcd/server.c.
3926 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3928 * Added the SILC Document generator to the scripts/silcdoc.
3929 It can be used to generate the Toolkit Reference Manual out
3930 of the source tree. Internally it will also use the RoboDoc
3931 generator now imported in util/robodoc.
3933 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3935 * Added couple of return's in rekey protocol if error orccurred
3936 during the protocol. The execution must be terminated.
3937 Affected file silcd/protocol.c. Also, terminate the protocol
3938 always with timeout.
3940 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3942 * The client's Client ID was created initally from the wrong
3943 nickname (it could have been in format nick@host) in the
3944 silc_server_new_client. Affected file silcd/packet_receive.c
3946 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3948 * Added some SILC_LOG_ERROR's to various error conditions
3949 if client could not be added to ID cache. Affected files
3950 silcd/packet_receive.c and silcd/server.c.
3952 * When client's sock->user_data is freed, NULL also the
3953 client->router and client->connection pointers. Added check
3954 for these pointers being NULL to various places around the
3955 code. Affected file silcd/server.c.
3957 * Added client->data.registered == TRUE checks to various
3958 places around the code to assure that unregistered client's
3959 are not handled when it is not allowed. Affected file
3962 * Added `bool registered' fields to all
3963 silc_idlist_[server|client]_get_* routines to indicate whether
3964 the fetched client needs to be registered or not. Affected
3965 file silcd/idlist.[ch].
3967 * Add your own entry as registered to the ID cache in the
3968 server. Affected file server.c.
3970 * Fixed a bug in silc_server_new_server. The SilcServer was
3971 set as the new server's context instead of SilcServerEntry.
3972 This naturally caused some weird bugs.
3974 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3976 * Do not delete the channel rekey task when adding it
3977 for in silc_server_create_channel_key.
3979 * Changed the silc_server_create_channel_key to return
3980 TRUE or FALSE to indicate the success of the channel key
3983 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3985 * Fixed MSVC++ project files and added missing files to
3986 Makefiles under win32/.
3988 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3990 * Do not add TCP_NODELAY flag if the operating system
3991 does not have it defined. Affected files are
3992 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3994 * Fixed buffer overflow from Irssi SILC Client. Affected
3995 file irssi/src/fe-common/core/themes.c.
3997 * Fixed double free in client library in the file
3998 lib/silcclient/client.c when disconnecting from server.
4000 * Applied double free patch from cras to Irssi SILC client.
4001 Affected files irssi/src/core/[modules/expandos].c
4003 * Fixed the disconnection handling to Irssi SILC Client.
4004 The application must call silc_client_close_connection
4005 in ops->connect client operation in case of failure of
4006 the connection. Affected file is
4007 irssi/src/silc/core/client_ops.c.
4009 * Do not set sock->protocol to NULL in the function
4010 silc_client_close_connection after executing the protocol's
4011 final callback since the sock might not be valid anymore.
4012 Affected file lib/silcclient/client.c.
4014 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4016 * Do not enable SILC_THREADS if the linking with libpthread
4017 did not happen. Affected file configure.in.pre.
4019 * Added notion to protocol specification that server must
4020 verify the sent authentication payload with CMODE when
4021 setting the channel founder key. Implemented it to the
4022 server. Affected file silcd/command.c.
4024 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4026 * Added _EXTRA_DIST SILC distribution variable to the
4027 distributions file. It is used to conditionally add extra
4028 files or directories to the specific distribution. Affected
4029 files ./prepare, Makefile.am.pre and distributions.
4031 Removed the `_' from the start of the distribution names.
4034 * Added README.WIN32 for instructions to compile the Toolkit
4037 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4039 * Fixed a double free in disconnection in the server. Affected
4040 file is silcd/server.c.
4042 * Fixed the lib/silcske/groups.c to work now also with GMP
4043 MP library. The string conversion did not work when using
4044 specific base and the base is indicated in the string as well.
4046 * Created win32/ directory which now includes MSVC++ specific
4047 stuff so that toolkit (DLLs) may be compiled with MSVC++.
4048 It will appear only in the toolkit distribution
4050 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4052 * Changed the key material distribution function in case when
4053 the hash output is too short. The data is now concatenated
4054 a bit differently than it used to. Made the change to the
4055 SKE protocol specification.
4057 * Added better GMP detection to configure.in.pre. A patch
4060 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4062 * Fixed a minor bug in SKE that might cause some problem on
4063 some platforms. Affected file lib/silcske/silcske.c.
4065 * Added the cookie checking for initiator in the SKE. It checks
4066 that the responder returns the sent cookie unmodified. The
4067 affected file is lib/silcske/silcske.c. Added new SKE
4068 error type INVALID_COOKIE that can be sent during the
4069 negotiation. Fixed some memory leaks as well.
4071 * Added the "invalid cookie" error message to Irssi SILC client's
4074 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4076 * Added `task_max' field to the SilcClientParams to indicate
4077 the maximum tasks the scheduler can handle. If set to zero,
4078 default values are used. Affected file lib/silcclient/silcapi.h.
4080 * Fixed memory leaks in silc_client_close_connection. Affected
4081 file lib/silcclient/client.c.
4083 * Added silc_client_del_client_entry to client library to free
4084 all memory of given client entry. Affected file is
4085 lib/silcclient/idlist.[ch].
4087 * Added new functions silc_client_del_channel and
4088 silc_client_del_server to delete channel and server entries.
4089 Affected file lib/silcclient/[silcapi.h/idlist.c].
4091 * Removed silc_client_del_client_by_id from silcapi.h.
4093 * Fixed the INFO command to return the server's own info
4094 correctly when querying by Server ID. Affected file is
4097 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4099 * Removed the non-blocking settings in WIN32 code in the
4100 silc_sock_[read/write] and added SleepEx instead. Affected
4101 file lib/silcutil/win32/silcwin32sockconn.c. The availability
4102 of input data is now checked with FIONREAD and ioctlsocket.
4104 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4106 * Call silc_schedule_task_del_by_context in the
4107 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
4108 Affected file lib/silccore/silcprotocol.c.
4110 * Call silc_protocol_cancel for active protocols in the
4111 silc_server_close_connection if the funtion
4112 silc_server_free_sock_user_data has not been called.
4113 Affected file silcd/server.c.
4115 * Generic tasks cannot be deleted using the del_by_fd
4116 task deleting function since generic tasks does not match
4117 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
4119 * Added a notion to SILCOPER help file that the SILCOPER works
4120 only on router server, not on normal server.
4122 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4124 * Added for WIN32 support for the new scheduler as well.
4125 Affected file lib/silcutil/win32/silcwin32schedule.c.
4127 * Fixed the SHA1 implementation to work on various platforms.
4129 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4131 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
4132 API. It is part of the scheduler now. Everything else is
4133 as previously but some functions has changed their names.
4134 Checkout the lib/silcutil/silcschedule.h for the interface.
4135 Updated all applications to use the new interface. Affected
4136 files are lib/silcutil/silcschedule.[ch].
4138 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4140 * Found a bug in the SKE implementation. The HASH value,
4141 specified by the protocol, was not computed correctly. The
4142 public key of the responder was not added to the computation
4143 even though it is mandatory. Affected file lib/silcske/silcske.c.
4144 This unfortunately causes incompatibilities with older
4145 clients and servers.
4147 * Added WIN32 specific network init and uninit functions:
4148 silc_net_win32_init and silc_net_win32_uninit to init and uninit
4149 the Winsock2. Affected file lib/silcutil/silcnet.h and
4150 lib/silcutil/win32/silcwin32net.c.
4152 * Set the socket always to nonblocking mode on WIN32 after
4153 reading data or writing data. Affected file is
4154 lib/silcutil/win32/silcwin32sockconn.c.
4156 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4158 * Fixed various compilation problems under WIN32. Affected
4159 files lib/silcutil/win32/silcwin32thread.c and
4160 lib/silcutil/win32/silcwin32schedule.c.
4162 * Removed all _internal.h #includes from public header
4163 files. Internal headers must never be included from
4166 Removed also the lib/silcske/payload_internal.h file.
4168 * All include files that may be needed (public and some others
4169 included by the public headers) by application developers are
4170 now copied to the ./includes directory. It does not copy any
4171 internal headers. Affected file Makefile.defines.pre and all
4172 Makefile.am's under lib/ and subdirs.
4174 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4176 * Do not change the ~/.silc directory's permissions automatically.
4177 Affected file irssi/src/silc/core/clientutil.c.
4179 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4181 * Do not cancel the protocol in silc_server_close_connection
4182 it might cause recursion. Now cancelled in the function
4183 silc_server_free_sock_user_data. Affected file silcd/server.c.
4185 * Fixed the silc_server_remove_clients_by_server to regenerate
4186 the channel keys correctly finally. Added also new function
4187 silc_server_remove_clients_channels to actually do it.
4188 Affected file silcd/server.c.
4190 * Fixed the silc_server_new_channel to not crash by giving
4191 wrong router to the new channel. Affected file is
4192 silcd/packet_receive.c.
4194 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4196 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
4197 which is given as argument to the silc_client_alloc now.
4198 It can be used to configure the client and set various parameters
4199 that affect the function of the client.
4201 * The USERS command in server did not check whether the channel
4202 is private or secret. Affected file silcd/command.c.
4204 * Added new argument to the USERS command in protocol specification.
4205 The USERS command now can take the channel name as argument
4206 as well. Added support for this in client and server and
4207 updated the protocol specs.
4209 * Completed the GETKEY command in client. It can be now used
4210 to fetch also servers public key not only some clients.
4211 Affected files lib/silcclient/command[_reply].c.
4213 * Added silc_client_get_server to return server entry by the
4214 server name. Affected files lib/silcclient/silcapi.h and
4217 * Redefined the IDENTIFY command in protocol specification to be
4218 more generic. It now can be used to query information about
4219 any entity in the SILC Network, including clients, servers and
4220 channels. The query may be based either the entity's name
4221 or the ID. Added support for this in both client and server.
4223 Affected files silcd/command.c and lib/silcclient/command.c
4224 and command_reply.c.
4226 * Optimized the WHOIS and WHOWAS commands in the server. Removed
4227 the _from_client and _from_server functions. Affected file
4230 * Added silc_client_get_channel_by_id_resolve to the file
4231 lib/silcclient/silcapi.h to resolve channel information by
4232 its ID. Added also silc_client_get_channel_by_id that
4233 does not resolve it from the server.
4235 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4237 * Added SilcServerEntry context into the client library
4238 to represent one server. The INFO command now allocates
4239 these to save the resolved server info. For now on the
4240 client library will also keep information about servers,
4241 connected and resolved with INFO.
4243 The INFO command now allocates the SilcServerEntry context
4244 and saves the server info there. The COMMAND_REPLY in
4245 the INFO now returns the parameters to application in
4246 same order as defined in the protocol specification.
4248 The entries are cached in the client->server_cache.
4250 * The INFO command is now issued after received the Client ID
4251 from the server. Affected file lib/silcclient/client.c.
4253 * The CMODE_CHANGE notify may now return also an SilcServerEntry
4254 to the application as the mode changer might be server.
4255 It is guaranteed that NULL is not returned anymore to the
4256 application. Affected file lib/silcclient/client_notify.c.
4258 The ID Type is now also passed to the application so that
4259 it can check whether the returned entry is SilcClientEntry
4262 Added new function silc_client_get_server_by_id to return
4263 the server entry by ID. Affected files are the
4264 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
4266 * Do not create the channel in the Irssi SILC Client when issuing
4267 the JOIN command but when received the sucessful JOIN command
4268 reply. Otherwise the channel might get created even though we
4269 could not join it. The Affected file is
4270 irssi/src/silc/core/[silc-channels.c/client_ops.c].
4272 * Fixed a channel joining bug in router. The router must also
4273 check the channel modes, invite and ban lists etc. when serving
4274 the JOIN command sent by normal server. Affected file is
4275 silcd/command.c. The router now resolves the client's
4276 information from the server who sent the JOIN command if it
4277 does not know it, and processes the JOIN command only after
4280 * Changed the SilcCommandCb to take new argument; void *context2.
4281 Affected file lib/silccore/silccommand.h
4283 The second argument in the command callbacks in the server now
4284 includes the SilcServerCommandReplyContext if the command was
4285 called as pending command callback from the command reply.
4286 Otherwise it is NULL. When called as pending the status of the
4287 command reply will be checked and if it was erronous the
4288 error will be sent to the original sender of the command.
4289 This way the client always receives the error messages even
4290 though the server was actually the one who received the error
4291 when it resent the command to router, for example. Affected
4292 files silcd/command[_reply].[ch].
4294 * Fixed sending WHOWAS command's error message to client if
4295 the requested client could not be found. It was missing.
4298 * Changed the CMODE and CUMODE commands reply arguments in the
4299 protocol specification. The Channel ID is now sent in both
4300 of the commands to identify the channel. Implemented this
4301 new feature to the client and server. Affected files
4302 lib/silcclient/command_reply.c and silcd/command.c.
4304 * Made better checks for invite and ban lists in the JOIN
4305 command in server. Affected file silcd/command.c.
4307 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4309 * The server now performs the incoming host IP/DNS lookup
4310 using the silc_socket_host_lookup and thus does not block
4311 the server anymore. Affected file silcd/server.c.
4313 * Completed the multi-thread support for SILC Scheduler in
4314 the lib/silcutil/silcschedule.c.
4316 * Fixed the configure.in.pre to detect the pthread correctly
4319 * Fixed a deadlock in silc_task_queue_wakeup in the file
4320 lib/silcutil/silctask.c.
4322 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4324 * Added new function silc_schedule_wakeup that is used in
4325 multi-threaded environment to wakeup the main thread's
4326 schduler. It needs to be used when a thread adds a new task
4327 or removes a task from task queues. After waking up, the
4328 scheduler will detect the task queue changes. If threads
4329 support is not compiled in this function has no effect.
4330 Implemented the wakeup mechanism to both Unix and WIN32
4331 systems. Affected files are lib/silcutil/silcschedule.[ch],
4332 lib/silcutil/unix/silcunixschedule.c and the
4333 lib/silcutil/win32/silcwin32schedule.c.
4335 * Added new function silc_task_queue_wakeup to wakeup the
4336 scheduler by the specified task queue. Affected file
4337 lib/silcutil/silctask.[ch].
4339 * The silc_socket_host_lookup_start now wakes up the scheduler
4340 after adding the timeout task. Affected file is
4341 lib/silcutil/silcsockconn.c.
4343 * The silc_socket_host_lookup is synchronous now if the threads
4344 support is not compiled in. However, the callback is still
4345 called asyncronously through the scheduler, anyway. Affected
4346 file lib/silcutil/silcsockconn.c.
4348 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4350 * Added new function silc_socket_host_lookup to perform
4351 asynchronous IP and FQDN lookups for the socket connection.
4352 Affected files lib/silcutil/silcsockconn.[ch].
4354 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4356 * Added SILC_MUTEX_DEFINE to define the mutex on environments
4357 that may or may not compile the mutex support in.
4359 Changed the silc_mutex_alloc interface. It allocates the
4360 mutex now to the sent pointer and returns TRUE or FALSE.
4362 Affected file lib/silcutil/silcmutex.h.
4364 * Wrote the SILC Task Queue interface to support multi-threads.
4365 Affected file lib/silcutil/silctask.[ch].
4367 * Wrote the SILC Scheduler to support multi-threads. Affected
4368 file lib/silcutil/silcschedule.c.
4370 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4372 * Implemented the SILC Mutex API and SILC Thread API for WIN32
4373 in lib/silcutil/win32/.
4375 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4377 * Defined SILC Mutex API and SILC Thread API and implemented
4378 them for Unix. Affected files are
4379 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
4380 lib/silcutil/unix/silcunixmutex.c and
4381 lib/silcutil/unix/silcunixthread.c.
4383 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4385 * Fixed the silc_server_remove_clients_by_server's channel
4386 key re-generation. The hash table handling was incorrect
4387 and would not work with many channels. Affected file is
4390 * Fixed some memory leaks around the server code.
4392 * Rewrote the silc_server_get_users_on_channel to support IPv6
4393 based Client ID's. Affected file silcd/server.c.
4395 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
4396 specification. However, a separate document must be written
4397 to define the detailed signing procedure and the payload
4398 associated with the flag. Defined the flag to the
4399 lib/silccore/silcchannel.h as well.
4401 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4403 * Changed the dynamic tables to static size tables in the
4404 lib/silccrypt/silchmac.c.
4406 * Removed GCC dependencies from the code. A patch by cras.
4408 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4410 * Do not show the error "Error receiving packet bla bla"
4411 in server if it really was not an error (-2 means that reading
4412 is pending). Affected file silcd/server.c.
4414 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4416 * Fixed a possible crash in silc_server_remove_clients_by_server
4417 in silcd/server.c. Fixed there also some memory leaks.
4419 * Fixed the silc_idlist_replace_client_id. It could replace
4420 wrong key in the hash table. Affected file silcd/idlist.c.
4422 * Do not check whether there are global users on the channel
4423 if the channel->global_users is FALSE. Affected functions
4424 silc_server_remove_from_one_channel and
4425 silc_server_remove_from_channels in silcd/server.c. Also,
4426 do not check if the removed client is local as we can be
4427 sure that global client was not removed from the channel
4428 and checking for global users is not needed.
4430 * The silc_server_remove_clients_by_server now re-generates
4431 the channel keys correctly for those channels that had
4432 clients removed from them. Affected file silcd/server.c.
4434 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4436 * Found the reason of random crashes in the server. We weren't
4437 ignoring the SIGPIPE signal (which can be sent in write())
4438 and it crashed the server. Affected file silcd/silcd.c.
4440 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4442 * Assure that sock->user_data is not NULL in the function
4443 silc_server_packet_send in silcd/packet_send.c.
4445 * Disconnect the remote connection if it could not be added
4446 to any ID lists in the server. The affected file is
4449 * Check in silc_server_packet_send[_real/dest] that the
4450 socket is not disconnecting and ignore the data if it is.
4451 Affected file silcd/packet_send.c.
4453 * Define inline to __inline on native WIN32 compilation.
4454 Affected file includes/silcwin32.h.
4456 * Added some explicit type casts for inline code since MSVC
4457 require them. Affected files lib/silcutil/silcbuffer.h,
4458 lib/trq/silcdlist.h and lib/trq/silclist.h.
4460 * Print warning in log files from now on if the packet
4461 decryption fails. Affected file silcd/server.c.
4463 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4465 * Changed the `say' client operation's interface to accept
4466 new `type' argument to indicate the type of the message sent
4467 by the library. The application may filter the library's
4468 messages according the type. The affected file is the
4469 lib/silcclient/silcapi.h.
4471 * Added two new functions to lib/silcclient/silcapi.h:
4472 silc_client_del_client and silc_client_del_client_by_id.
4473 Affected file lib/silcclient/idlist.c.
4475 * Moved the clientincludes.h from includes/ to silc/ and
4476 serverincludes.h from includes/ to silcd/.
4478 * The modes for the CMODE and CUMODE are now passed as
4479 uint32 for application with COMMAND_REPLY. The affected
4480 file is lib/silcclient/command_reply.c.
4482 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4484 * /WHOIS without arguments shows client's own information.
4485 Affected file lib/silcclient/command.c.
4487 * Changed PING to not accept any arguments. The specs
4488 says that client can ping only the connected server so
4489 requiring an argument is not needed. Affected file is
4490 lib/silcclient/command.c.
4492 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4494 * Fixed a fatal bug in private message sending and reception
4495 encryption and decryption when using private message keys.
4496 The implementation was incorrect and did not follow the
4497 specification. It causd that some of the message were
4498 lost since it did not use the sending and receiving keys
4499 as the protocol suggests. This has been fixed and will cause
4500 incompatibilities with older clients when sending private
4501 message encrypted with private message keys. Affected files
4502 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
4503 and various other in Irssi SILC Client.
4505 Added `responder' boolean argument to the functions
4506 silc_client_add_private_message_key[_ske] to indicate when
4507 the key is added as responder or initiator of the key
4510 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4512 * Removed the silc_ske_check_version function and created
4513 a SilcSKECheckVersion callback. Added also a function
4514 silc_ske_set_callbacks that is now used to set all SKE
4515 callbacks. The callback functions are not given to
4516 the SKE functions anymore, but this function is used to
4519 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
4521 * Added `silc_version' argument to the silc_client_alloc
4522 to define the version of the application for the library.
4523 The library will use the version string to compare it
4524 against the remote host's (usually a server) version
4525 string. Affected file lib/silcclient/silcapi.h
4527 * Added the KE protocol context to Key Agreement context
4528 in client library so that we can abort the SKE if it
4529 is in process when we get timeout. Affected file is
4530 lib/silcclient/client_keyagr.c.
4532 * Do not resolve the client ID forever if it returns in the
4533 first time that such client does not exist. This was done
4534 for example with private message. Affected file is
4535 lib/silcclient/client_prvmsg.c.
4537 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4539 * Do not add regex.h for WIN32. The affected file
4540 includes/silcincludes.h.
4542 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
4543 not work yet 100%. It generates the DLL's automatically
4544 when compiling with --with-win32 under cygwin.
4546 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4548 * lib/contrib/regex.c is not compiled on WIN32.
4550 * Added silc_net_get_socket_opt function to the
4551 lib/silcutil/silcnet.h.
4553 * Added includes/silcwin32.h for WIN32 specific includes
4556 * Do not use ptime structure or any of the posix process
4557 functions on WIN32 in lib/silccrypt/silrng.c.
4559 * Added silc_gettimeofday to provide generic function
4560 for struct timeval on all platforms. Added the function
4561 to lib/silcutil/silcutil.h.
4563 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4565 * Moved the lib/silccore/silcsockconn.[ch] to the utility
4566 library as they clearly belong there. As a plus side we
4567 can make the actual socket connection routines platform
4570 Added also new generic function silc_socket_read and
4571 silc_socket_write (that used to be silc_packet_[read/write].
4572 The implementation of these are platform specific.
4574 * Added WIN32 specific routines of silc_socket_[read/write]
4575 to lib/silcutil/win32/silcwin32sockconn.c.
4577 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4579 * Added preliminary support for native WIN32 compilation under
4580 cygwin (using the -mno-cygwin option for GCC) to the
4581 ./configure.in.pre. The --with-win32 now prepares the
4582 compilation for native WIN32.
4584 * Rewrote the SILC Scheduler interface in the file
4585 lib/silcutil/silcschedule.h. The scheduler is now context
4586 based and does not have anymore any global static scheduler.
4587 Moved the Unix scheduler to the lib/silcutil/unix/ directory
4588 and created lib/silcutil/win32 directory for WIN32 based
4591 * Added Unix specific network routines to the
4592 lib/silcutil/unix/silcunixnet.c and the old
4593 lib/silcutil/silcnet.c includes now only generic routines.
4595 Added WIN32 specific network routines to the
4596 lib/silcutil/win32/silcwin32net.c.
4598 * Added Unix specific utility functions from the
4599 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
4601 * Added WIN32 SILC Scheduler to the file
4602 lib/silcutil/win32/silcwin32schedule.c. The code is of course
4605 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4607 * Do not handle JOIN notify in the server if the target client
4608 is not registered (idata->registered == FALSE). The affected
4609 file is silcd/packet_receive.c.
4611 * Update the nickrec->founder in event_cumode in the Irssi SILC
4612 client. Affected file irssi/src/silc/core/silc-channels.c.
4614 * Fixed the CUMODE_CHANGE notify handling in the server when
4615 server and router are announcing their clients on channels.
4616 Now the mode changes are saved and notified correctly. The
4617 affected file is /silcd/packet_receive.c.
4619 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
4620 They really did not replace the cache entry in the ID Cache.
4621 Now they do that. Affected file silcd/idlist.c.
4623 * Fixed the KICK notify handling in the Irssi SILC client to
4624 update the channel records so that the kicked client does not
4625 appear to be on the channel. The affected file is
4626 irssi/src/silc/core/silc-channels.c.
4628 * Always update the conn->current_channel when executing command
4629 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
4631 * Fixed the KILL notify handling in Irssi SILC client to remove
4632 the killed client on all channels.
4634 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4636 * Fixed the silc_parse_command_line to remove extra spaces
4637 from the start and end of the arguments. Affected file is
4638 lib/silcutil/silcutil.c.
4640 * Cancel and free any active protocol in the function
4641 silc_server_close_connection. Affected file silcd/server.c.
4643 * Cancel and free any active protocol in the function
4644 silc_client_close_connction. Affected file is
4645 lib/silcclient/client.c.
4647 * Do not execute the KILL command for clients that are in
4648 history (ie. they are not in the network). Affected file is
4651 * Fixed KILL notify handling, client does not crash anymore.
4652 Affected file irssi/src/silc/core/silc-channels.c.
4654 * Reduced the default packet buffer size from 2048 to 1024 in
4655 lib/silccore/silcpacket.c.
4657 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
4658 counter to the SKE context that is incresed when the SKE library
4659 performs async operation outside the library. If the outside
4660 process frees the SKE context and FREED status will be set
4661 and the library will detect after the sync operation that the
4662 libary is freed. The affected files are
4663 lib/silcske/silcske[_status].[ch].
4665 * Resolve the client entry information in the function
4666 silc_client_channel_message to assure that NULL pointer is not
4667 passed as client entry to the application. */
4669 * Fixed the task timeout calculation to assure that there is
4670 never negative timeouts. The affected file is
4671 lib/silcutil/silcschedule.c.
4673 * Fixed the channel user mode notification sending in server.
4674 It was sent point-to-point to the router (or to server by router)
4675 but it needs to be destined to a channel. The routines now
4676 supports sending the channel user mode notifys to the channels
4677 when announcing clients and channels. Affected files are
4678 silcd/server.c and silcd/packet_receive.c.
4680 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
4681 It did not actually replace the old channel entry in the cache.
4682 Affected file lib/silcclient/client_notify.c.
4684 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4686 * Fixed a possible crash in silc_packet_send_prepare. It now
4687 assures always that there is enough space in the buffer and
4688 at the tail area of the buffer (for MAC).
4690 Fixed the inbound buffer reallocation in silc_packet_read.
4691 It was old code and did not handle the reallocation correctly.
4694 The affected file is lib/silccore/silcpacket.c.
4696 * Fixed buffer overflow in silc_parse_nickname in the file
4697 lib/silcutil/silcutil.c.
4699 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4701 * make install generates new server keys only if there is not
4704 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4706 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
4707 Added check that if the NOREPLY is set then we will not send
4708 the away message. This avoids infinite loop of away messages
4709 if both clients are away. The affected file is
4710 lib/silcclient/client_prvmsg.c.
4712 * Fixed client crash if /NICK was given without arguments.
4713 Affected file lib/silcclient/command.c.
4715 * Server does not send the invite list in INVITE command back
4716 to the client if the list was not altered. Added this notion
4717 to the protocol spec as well. Affected file silcd/command.c.
4719 Fixed possible crash in INVITE command by checking the
4720 value of silc_server_get_client_route command.
4722 * Fixed the INVITE notify type handling. The arguments are now
4723 taken in correct order and client does not crash. The affected
4724 file is irssi/src/silc/core/silc-channels.c.
4726 Removed the "Inviting xxx to channel" message from the
4727 client library away and let the application handle it.
4728 Affected file lib/silcclient/command.c. Added that message
4729 to Irssi SILC client's message formats.
4731 * Fixed CMODE command crash in client. It now checks the
4732 amount of arguments correctly and does not crash. The affected
4733 file is lib/silcclient/command.c.
4735 * Do not create new channel automatically in silc_channels_join
4736 but check whether the channel by that name already exists.
4737 Affected file irssi/silc/core/silc-channels.c.
4739 * Do not send the SERVER_SIGNOFF to router if the disconnected
4740 entity was the router. Affected file silcd/server.c.
4742 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
4743 SILC client as it was missing from there.
4745 Added the handling of the KICK notify to the Irssi SILC client
4746 as it was missing. Added "you have been kicked" message to
4747 Irssi SILC client's message modules formats.
4749 Added the handing of the KILL notify to the Irssi SILC client
4750 as it was missing. Added the kill message module formats
4753 The affected file is irssi/src/silc/core/silc-channels.c.
4755 * The router did not save the channel mode the server announced.
4756 Affected file silcd/packet_receive.c.
4758 * Fixed a possible crash in INFO command in server. If the
4759 server did not provide the server info it crashed. Affected
4760 file silcd/command.c.
4762 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4764 * Fixed the GETKEY command in the server to check also the
4765 global list. Otherwise the GETKEY would not work correctly
4766 in normal SILC server. Affected file silcd/command.c.
4768 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4770 * Fixed GETKEY crash, it crashed if the command did not succseed.
4772 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4774 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
4775 is now real and not just an macro interface to GMP.
4777 Removed the entire GMP from the source tree and imported new
4778 NSS MPI library instead. Reason for removing GMP is that it is
4779 extremely large and compiles extremely slow. The NSS MPI
4780 is only a few files and compiles in less than 10 seconds.
4781 The speed is also about the same as GMP. The MPI is imported
4782 to lib/silcmath/mpi.
4784 If the system has GMP installed we will still use the GMP.
4785 If it is not then the NSS MPI will be compiled.
4787 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4789 * Merged a long nickname (127 characters long) crash bugfix from
4790 Irssi CVS tree. Affected file irssi/src/core/misc.c.
4792 * Merged a freed memory reference bugfix from Irssi CVS tree.
4793 Affected file irssi/src/core/commands.c.
4795 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4797 * Added the server's public key sving and verification to the
4798 server when performing the SKE. This was missing and the
4799 remote server's (or router's) public key was accepted without
4800 checking whether we have it previously or trust it at all.
4801 Affected file silcd/protocol.c.
4803 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4805 * Check in the silc_server_timeout_remote if protocol is active
4806 and make sure that the protocol's final callback is called so
4807 that all memory if freed. Affected file silcd/server.c.
4809 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4811 * silc_server_whois_send_reply crashed the server if the nickname
4812 was 127 characters long. Affected file silcd/command.c.
4814 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4816 * Added sanity check to the silc_server_new_client. If the hostname
4817 is provided inside username then check that the provided hostname
4818 really is the same as the resolved one. If the hostname was not
4819 resolved then check it from the public key. Affected file is
4820 silcd/packet_receive.c.
4822 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
4823 if the server disconnected us and the connection is not valid
4824 anymore. Affected file irssi/src/silc/core/silc-channels.c.
4826 * Moved the silc_client_[chmode|chumode|chumode_char] away from
4827 the library to the lib/silcutil/silcutil.[ch].
4829 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4831 * Close log file after open. Affected file
4832 lib/silcutil/silclog.c.
4834 * Check whether sock == NULL in silc_client_send_packet and return
4835 if it is. Affected file lib/silcclient/silcclient.c.
4837 * Check rec->entry == NULL in the Irssi SILC Client before
4838 sending the channel message. Affecte file is
4839 irssi/src/silc/core/silc-servers.c.
4841 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4843 * Merged a splitted window bugfix from Irssi CVS tree. The
4844 affected file is irssi/src/fe-text/textbuffer-view.c.
4846 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
4847 It did not print nickname.
4849 * Improved the distributions system a bit.
4851 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4853 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
4854 irssi/src/fe-text/gui-window.c.
4856 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
4857 to in-active server. The affected file is
4858 irssi/src/silc/core/client_ops.c.
4860 * Resolve the client in USERS command reply if the entry does
4861 not have username resolved. The affected file is
4862 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
4863 command to WHOIS command to really resolve stuff. The USERS
4864 is not used any more in any critical section so WHOIS can
4865 be used even though it might be slower than IDENTIFY.
4867 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
4870 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4872 * Changed the protocol API a bit more consistent in the
4873 lib/silccore/silcprotocol.[ch].
4875 * Changed the following headers to ROBODoc format:
4877 lib/silccore/silcpayload.h
4878 lib/silccore/silcprotocol.h
4879 lib/silccore/silcsockconn.h
4881 All core library headers are now formatted.
4883 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4885 * Fixed a bug in Irssi SILC client; do not show that you are
4886 server/router operator if you really are not. Affected file is
4887 irssi/src/silc/core/client_ops.c.
4889 * Renamed silc_command_free_payload to silc_command_payload_free.
4890 Affected file lib/silccore/silccommand.h
4892 * Added silcmath.h to include the prototoypes of various routines
4893 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
4896 * Changed the following headers to ROBODoc format:
4898 lib/silccore/silcchannel.h
4899 lib/silccore/silccommand.h
4900 lib/silccore/silcid.h
4901 lib/silccore/silcidcache.h
4902 lib/silccore/silcmode.h
4903 lib/silccore/silcnotify.h
4904 lib/silccore/silcpacket.h
4905 lib/silcmath/silcmath.h
4907 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4909 * Added checking to the server code not to start the server if
4910 ciphers and stuff are not configured properly. Affected files
4911 silcd/serverconfig.[h] and silcd/server.c.
4913 * Changed the layout of the header files of the public interfaces
4914 in the SILC libraries. The new layout supports ROBODoc
4915 documentation tool (and some others) so that it is easy to create
4916 a library reference manual. All the other headers and source
4917 code must still follow the CodingStyle document. Also source
4918 code must not include these ROBODoc stuffs, only the headers.
4919 Furthermore, all public interface headers must now be named
4920 by using `silc' prefix, example: silcapi.h, silccipher.h.
4921 Some files were renamed due to this. All the other headers
4922 must not be used as public interfaces. I will update the
4923 CodingStyle document later. Changed following headers, so far:
4925 lib/silcclient/silcapi.h
4926 lib/silccore/silcauth.h
4927 lib/silccore/silcprivate.h
4928 lib/silccrypt/silcdh.h
4930 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4934 * Removed silc_client_packet_send_flush from the client library
4935 as it is not needed. Affected file lib/silcclient/client.[ch].
4937 * Added printing of message of unresolved authentication method
4938 to the Irssi SILC client. Added it to the module formats.
4939 Removed the same message from the client library.
4941 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4943 * Added new distribution feature, DISTLABEL. Every distribution
4944 can define own preprocessor label that can be used in the
4945 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
4946 file distributions, acconfig.h.pre and prepare.
4948 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4950 * Added Makefile.defines_int to include the actual definitions
4951 for Makefile.defines.in. Tested the new distribution system,
4952 created distributions and tested installation.
4954 * Added AWAY message printing to the Irssi SILC client. Added
4955 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
4957 * Added SCONNECT command to call the SILC's CONNECT command.
4958 Cannot use CONNECT directly since Irssi uses that internally.
4959 Affected file irssi/src/silc/core/silc-servers.c.
4961 Added ACTION local command. It is same as ME command but takes
4962 the channel as mandatory argument.
4964 Rewrote some of the Irssi's help files to suite for SILC
4967 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4969 * Added Makefile.defines[.in] that should for now on be included
4970 in all Makefile.am file in the source tree. That file includes
4971 all common compilation definitions for SILC source tree.
4973 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4975 * Minor changes to the ./prepare script to change the package
4976 name according the distribution name to the configure.in.
4978 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4980 * Created new distribution system. Added file `distributions'
4981 that defines all the distributions that can be created out of
4982 the SILC source tree. The ./prepare script now reads that
4983 file to determine how to prepare the distributions. The
4984 first argument to the ./prepare is the name of the distribution
4985 and second is the version of the distribution. If given
4986 without arguments it creates the default (toolkit) distribution
4987 with the default version (defined in ./prepare).
4989 All Makefile.am files that are subject to the distributions
4990 are now named as Makefile.am.pre. These are ./Makefile.am
4991 and lib/Makefile.am. Others may be changed later.
4993 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4995 * Added invite list, ban list, some key management and connection
4996 error message printing to module formats in the Irssi SILC client.
4998 * Added new silc_client_set_away_message to set the away message
4999 that is back to the person who sent private message. The
5000 affected file lib/silcclient/silcapi.h and the
5001 lib/silcclient/client_prvmsg.c.
5003 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5005 * Fixed the private message sending in the Irssi SILC client,
5006 added local command KEY to the Irssi SILC client.
5008 Added key management and key agreement message formats to the
5009 irssi/src/fe-common/silc/module-formats.[ch].
5011 Added USERS (alias WHO) printing, server/router operator
5012 indication and LIST command printing to the module formats.
5014 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5016 * Fixed channel joining notify handling, cumode notify handling
5017 from Irssi SILC client.
5019 * Added SILC specific module-formats to the Irssi SILC client so
5020 that SILC specific message hilighting, colors etc is possible.
5021 Affected file irssi/src/fe-common/silc/module-formats.[ch].
5023 Added channel mode, channel user mode, actions, notices,
5024 whois and whowas printing to the the module-formats.c.
5026 * Fixed a bug in channel deletion in the server. The channel
5027 is not left to the cache even if the channel founder auth mode
5028 is set when there are no users anymore on the channel. Affected
5029 file silcd/server.c.
5031 * The silc_net_localhost now resolves the entire hostname including
5032 the domain name. Affected file lib/silcutil/silcnet.c.
5034 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5036 * Changed the ask_passphrase client operation to be ascynchronous.
5037 It has now a completion callback and a context that the
5038 application must call after it has got the passphrase from
5039 the user. Affected files lib/silcclient/silcapi.h,
5040 lib/silcclient/protocol.c, lib/silcclient/command.c and
5043 Added SilcAskPassphrase callback that the application calls
5044 to deliver the passphrase to the library.
5046 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
5047 The public key verification and especially a certificate
5048 verification is asynchronous procedure.
5050 Added new SILC_SKE_STATUS_PENDING status to indicate the
5051 request is pending and a callback will be called to finalize
5054 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
5055 indicate that remote end did not send its public key (or
5056 certificate), even though we require it. Added check for this
5057 condition in the SKE. This was a security bug, now fixed.
5059 Defined new SilcSKEVerifyCbCompletion callback that is called
5060 when the verification process is completed.
5062 The affected files lib/silcske/silcske_status.h and
5063 lib/silcske/silcske.[ch].
5065 * Changed the verify_public_key client operation to be async
5066 as well. Defined SilcVerifyPublicKey callback that is used to
5067 indicate the success of the public key verification process.
5069 Changed the server and client to use the new async client
5072 * Changed the Irssi SILC client's internal scheduler to be called
5073 twice as many times as it used to be. As a result the client
5074 should be a bit faster now. Affected file is
5075 irssi/src/silc/core/silc-core.c.
5077 * Added support to Irssi SILC client of asynchronous public key
5078 verification and passphrase inquiry. Affected file is
5079 irssi/src/silc/core/silc-core.c.
5081 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5083 * Do not say "You have left channel %s" in client library.
5084 Moved it to the application. Affected files are
5085 lib/silcclient/command.c and silc/client_ops.c.
5087 * Fixed silc_client_get_clients. Command context was not
5088 duplicated and was freed memory in the callback. Affected
5089 file lib/silcclient/idlist.c.
5091 * Do not say "you are now talking..." on JOIN command in the
5092 client library. The appliation must handle it.
5094 * Do not say ".. changed topic to" in command reply in the
5095 client libary. The application must handle it.
5097 * Fixed TOPIC command sending in the client library.
5099 * Fixed a memory leak in silc_client_command_free in the file
5100 lib/silcclient/command.c.
5102 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5104 * Imported a modified version of Irssi client to the source tree.
5105 The Irssi will be used to create a new client called
5106 Irssi SILC. Imported to irssi/.
5108 Added silc_core_init_finish function to the Irssi. Affected
5109 file irssi/configure.in.
5111 A lot changes in the Makefile.ams around the irssi tree.
5113 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5115 * Do not rehash if the new size is same as the old size of the
5116 hash table, in the silc_hash_table_rehash*. The affected file
5117 lib/silcutil/silchashtable.c.
5119 * Replaced hash_table_del_by_context calls from the server
5120 (when channel->user_list and client->channels) to the
5121 hash_table_del as it is sufficient and faster.
5123 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5125 * Added silc_hash_table_list, silc_hash_table_get and the
5126 SilcHashTableList structure to provide an alternative way to
5127 traverse the hash table. The affected files are
5128 lib/silcutil/silchashtable.[ch].
5130 * Changed the server's idlist routines to use the hash table
5131 routines to optimize the code.
5133 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5135 * Replaced the client entry's `channel' list and channel entry's
5136 `user_list' list to hash tables for optimized lookup. Changed
5137 the code to use the hash table interface around the code.
5138 Affected file lib/silcd/idlist.[ch].
5140 * Added `auto_rehash' boolean argument to the function
5141 silc_hash_table_alloc to indicate whether the hash table should
5142 auto-rehash when it thinks is appropriate time. It will
5143 increase the hash table size if the there is twice as much
5144 entries in the table than the size of the table, and will
5145 decrease the size if there are twice as less entries than
5146 the size of the table.
5148 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5150 * Fixed silc_xxx_get_supported to not crash at some circumstances.
5152 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5154 * silc_idcache_purge_by_context deletes the entry now by context
5155 as it is supposed to do. Affected file lib/silccore/idcache.c.
5157 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
5158 client is not anymore valid (WHOWAS givens the info) and not
5159 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
5161 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5163 * Removed the `data' and `data_len' arguments from the ID Cache
5164 interfaces and added `name' argument. ID Cache does not handle
5165 anymore the binary data only a names associated with given ID.
5167 * When hashing a Client ID with silc_hash_id the entire ID is
5168 not hashed anymore, instead only the hash of the Client ID is
5169 hashed. This way we can access the Client ID from the cache
5170 with Client ID but with the hash of the ID (which is a hash of
5171 the nickname) as well without any difference in performance.
5173 Added also silc_idcache_find_by_id_one_ext to do one on one
5174 searching when we have the actual ID. Added also function
5175 silc_hash_client_id_compare. The affected files are
5176 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
5178 * When hashing the name associated with a ID it is always done
5179 in lowercase. This way we can access the cache without worrying
5180 about case-sensitivity, even though, for example nicknames are
5183 * Fixed a bug in server with channel message sending. It put
5184 wrong ID type as destination ID. The affected file
5185 silcd/packet_send.c.
5187 * silc_idcache_del_by_context now deletes from all hash tables
5188 by context. Affected file lib/silccore/idcache.c.
5190 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5192 * Changed the client library to use the new ID Cache interface.
5193 Changes around the source tree.
5195 * Added silc_hash_table_rehash_ext to rehash with specific
5196 hash function. Affected file lib/silcutil/silchashtable.[ch].
5198 * Added silc_hash_string_compare to compare two strings in the
5199 hash table. Affected file lib/silcutil/silcutil.[ch].
5201 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5203 * Added new function silc_idcache_del_by_context into the
5204 lib/silccore/idcache.[ch].
5206 * Changed the server's ID list routines to use the new ID Cache
5207 interface. Changes around the source tree.
5209 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5211 * Added silc_hash_table_del[_by_context]_ext functions in to the
5212 lib/silcutil/silchashtable.[ch].
5214 Removed silc_hash_table_find_all* routines and added new
5215 silc_hash_table_find_foreach to replace them.
5217 Added silc_hash_table_replace_ext function as extended
5218 replacing function. Separated the simple hash table interface
5219 from the extended hash table interface in the file
5220 lib/silcutil/silchashtable.h.
5222 * Fixed minor bugs and changed it to use some of the new
5223 hash table functions in lib/silccore/idcache.c
5225 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5227 * Added new function silc_hash_table_find_all to return all keys
5228 in the hash table by the specified key. As the hash table is
5229 collision resistant it also makes it possible to have several
5230 duplicate keys in the hash table. This function may be used to
5231 find all of the keys from the hash.
5233 Added user_context arguments to the SilcHashFunction,
5234 SilcHashCompare and SilcHashDestructor to deliver user specified
5237 Added new fuctions silc_hash_table_find[_all]_ext to do
5238 extended lookup with specified hash and compare functions and
5239 specified user contexts.
5241 Added new function silc_hash_table_add_ext to add the key
5242 with specified hash function and user context.
5244 Added new function silc_hash_table_foreach to traverse all
5245 entrys in the hash table. Added SilcHashForeach callback
5248 Added new function silc_hash_table_del_by_context to delete
5249 the entry only if the context associated with the key matches.
5251 Affected files are lib/silcutil/silchashtable.[ch].
5253 * Removed silc_hash_[server/client/channel]_id and added just
5254 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
5255 silc_hash_id_compare to compare two ID's using as the hash table
5256 comparison function. Added also silc_hash_data to hash
5257 binary data and silc_hash_data_compare to compare it.
5259 * Removed silc_idlist_find_client_by_hash as it is not needed
5260 anymore. Affected file silcd/idlist.[ch].
5262 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
5263 to use internally the SilcHashTable. The new ID Cache is a lot
5264 faster than the old one. Some of the ID Cache interface was also
5265 rewritten and obsolete and stupid functions were removed.
5267 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5269 * Added entry_count field to the SilcHashTable to keep the number
5270 of the entries in the table. Implemented the function
5271 silc_hash_table_rehash. Added new function
5272 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
5274 Fixed a minor bug in silc_hash_table_free.
5276 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
5277 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
5278 into the lib/silcutil/silcutil.[ch].
5280 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5282 * Implemented a collision resistant hash table into the
5283 lib/silcutil/silchashtable[ch]. See the header and the source
5284 for the SilcHashTable API.
5286 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5288 * Merged dotconf version 1.0.2 into lib/dotconf.
5290 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5292 * Do not compile anything in lib/silcsim/* if the SIM support
5293 is not enabled. The tree should now compile without problems
5296 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5298 * Compiled the SILC under cygwin. Compiled and tested briefly
5299 without problems. More tests needed. The SIMs didn't compile
5302 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
5304 * Fixed possible crash in silc_get_username in the
5305 lib/silcutil/silcutil.c.
5307 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5309 * Fixed a va_arg in silc/client_ops.c.
5311 * Oops, RC5 routines were named AES and caused some problems
5312 when not using SIM's. Affected file lib/silccrypt/rc5.c.
5314 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5316 * Added new SilcIDIP structure into the lib/silccore/id.h and
5317 replaced the old `ip' fields from all SILC ID's to that type.
5318 This is a step towards IPv6 support.
5320 The silc_id_get_len takes now the ID as an extra argument.
5321 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
5322 both IPv4 and IPv6 based ID's.
5324 The affected files are lib/silccore/id.[ch] and other files
5325 around the tree using these routines.
5327 * Removed the ID length arguments in server from various
5328 silc_server_send_notify_* routines -> they are not needed
5331 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5333 * Fixed memory leak in silc_encode_pem_file in the file
5334 lib/silcutil/silcutil.c.
5336 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5338 * Check minor version as well in the SKE. Affected files are
5339 silcd/protocol.c and lib/silcclient/protocol.c.
5341 * Added --identifier option to the server so that an identifier
5342 can be when creating the public key for the server. Affected
5343 file is silcd/silcd.c.
5345 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
5346 lib/silccrypt/silcpkcs.c.
5348 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5350 * Register default ciphers and stuff when using -C option with
5351 the server. Affected file sildc/silcd.c.
5353 * Put back the servers public key filename format, it is better
5354 than the new one. For now, the client keys are saved with the
5355 new filename format. The affected file silc/client_ops.c.
5357 * Implemented the Cipher API for the rest of the ciphers that
5358 did not implement it or implemented it the wrong way.
5360 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5362 * Register default ciphers and stuff when using the -S option
5363 in the client. Affected file silc/silc.c. Same also when
5364 creating new key pair with -C option.
5366 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5368 * Fixed the silc_verify_public_key client operation function to
5369 save the public keys differently. The fingerprint is now
5370 used as filename and not the hostname. This way also the
5371 client keys are saved uniquely and not with hostnames. The
5372 affected file is silc/client_ops.c.
5374 * Trimmed the silc_hash_fingerprint function to remove extra
5375 whitespaces from the end of the fingerprint. The affected
5376 file is lib/silccrypt/silchash.c.
5380 * Added silc_cipher_register_default function to register all
5381 default ciphers. It can be used when configuration files
5382 does not exist and the application does not want any specific
5383 ciphers in any specific order.
5385 The SilcDList is now used as silc_cipher_list dynamically
5386 allocated cipher list. Removed the static list all together
5387 and now all ciphers must be allocated to the dynamic list.
5388 The silc_cipher_alloc routine was changed to check only the
5391 All silc_cipher_* routines that used to return int returns
5394 The affected files lib/silccrypt/silccrypt.[ch].
5396 * The same thing was done to silc_hash_* as for silc_cipher_*
5397 routines. Affected files lib/silccrypt/silchash.[ch].
5399 * The same thing was done to silc_pkcs_* as for silc_cipher_*
5400 routines. Affected files lib/silccrypt/silcpkcs.[ch].
5401 Added also silc_pkcs_[un]register[_default] functions.
5402 Removed the data_context from the PKCS API.
5404 * Added silc_hmac_register_default function to register default
5405 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
5406 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
5407 to unregister all hmacs at once.
5409 * Register the default ciphers, hash functions, PKCSs and HMACs
5410 if client's configuration file does not exist. The affected
5413 * The client did not load the hash functions from the SIM
5414 modules at all. Added support for this. Affected file is
5415 silc/clientconfig.c.
5417 * When decoding public key with silc_pkcs_public_key_decode, check
5418 the supported algorithm only if PKCS are registered. Affected
5419 file lib/silccrypt/silcpkcs.c. The same was done with the
5420 silc_pkcs_private_key_decode.
5422 * Fixed the SILC List routines to keep the list always in order.
5423 It used to change the list's order when traversing the list but
5424 not it preserves the order. Affected file lib/trq/silclist.h.
5426 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5428 * Added the client library to use the SilcSocketConnection's
5429 reference counter (by silc_socket_dup) to prevent the bug that
5430 the socket object may be freed underneath async operation.
5432 * The name resolv library checking fixes in the configure.in.pre.
5435 * Created new version of the protocol drafts for future
5436 development. The -03 drafts are the ones that will be changed
5437 in the trunk now and the -02 will remain as they are.
5439 * Send list of CUMODE notifys to the router when announcing
5440 the channel users to the router. Affected file silcd/server.c.
5441 If the router receiving channel founder CUMODE for a channel
5442 that already has channel founder it will send CUMODE notify
5443 to the sender to remove the channel founder rights from the
5444 announced client. Affected file silcd/packet_receive.c.
5446 * The CUMODE notify may now use Server ID as well as the entity
5447 who changes the mode. Updated protocool specs.
5449 * Updated INSTALL and README files.
5451 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5453 * New web pages in the http://silc.pspt.fi. The pages was
5458 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5460 * Implemented the [DenyConnectin] config section in the server.
5461 Added silc_server_config_denied_conn to check whether incoming
5462 connection is denied. Affected file silcd/serverconfig.[ch].
5464 * Do not check the ports when checking the incoming configuration
5465 data if the port is 0, meaning any. Affected file is
5466 silcd/serverconfig.c.
5468 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5470 * Fixed buffer overflow in silc_string_compare in the file
5471 lib/silcutil/silcutil.c.
5473 * Fixed double free in silc_server_command_leave in the file
5476 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5478 * Fixed the version checking in the server. Affected file is
5481 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5483 * Fixed the configuration data fetching when accepting new
5484 connections in the server. Affected file silcd/server.c.
5486 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5488 * Added `sender_entry' argument to the function
5489 silc_server_packet_relay_to_channel so that we can check
5490 whether some destination actually belongs to the same route
5491 the sender belongs (ie, we must not resend the packet to the
5492 sender). Affected file silcd/packet_send.[ch].
5494 * Added `servername' field to the SilcClientEntry in the server
5495 to hold the name of the server where client is from. Affected
5496 file is silcd/idlist.h.
5498 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5500 * Moved the channel message encrypting in the router betwen
5501 router connections from silc_server_channel_message to the
5502 silc_server_packet_relay_to_channel since we want to check
5503 whether we have anybody channel before encrypting anything.
5504 Affected files silcd/packet_[receive/send].c.
5506 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5508 * Fixed the [AdminConnection] server config section to support
5509 multiple entries. Affected file silcd/serverconfig.c.
5511 * Added support into the server to check the validity of the
5512 incoming connection before executing any KE or authentication
5515 * The connection configuration is now saved to the KE and
5516 connection auth protocol contexts and not fetched anymore in
5517 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
5519 * The local hosts listenning address and port is also resolved
5520 now when starting the server. We want to have the socket object
5521 to include the real address and port for the listener. Added
5522 new function silc_net_check_local_by_sock into the files
5523 lib/silcutil/silcnet.[ch].
5525 * Fixed a broadcast bug in server -> do not broadcast if we
5528 * Fixed a routing bug. Do not route broadcast packets ever.
5529 Broadcast packets must be processed always and not routed since
5530 they may be destined to some other host than yourself and thus
5531 would get routed without no good reason. Affected file is
5534 * Added function silc_server_config_is_primary_route to check
5535 whether primary router connection has been configured (a router
5536 configuration that we are initiating). If there is not, we
5537 will assume that there is only two routers in the SILC network
5538 and we will use the incoming router connection as our primary
5539 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
5541 * Changed the order of the broadcasting. Broadcast _after_ the
5542 packet has been processed not before. Affected file is
5545 * Fixed a [ClientConnection] parsing bug. The port was never
5546 parsed correctly thus resulting to port 0. Affected file
5547 silcd/serverconfig.c.
5549 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
5550 argument and did not set the broadcast packet flag. Affected
5551 file silcd/packet_send.c. Fixed same bug in the function
5552 silc_server_send_notify as well.
5554 * If we receive NEW_ID packet for our own ID in the server, ignore
5557 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5561 * Removed the nickname from the Private Message Payload.
5562 Updated the code and the protocol specs.
5564 * Updated protocol specs for submitting to the IETF.
5566 * Tweaked the Random Number Generator a bit. Affected file
5567 lib/silccrypt/silcrng.c. Exported a new function
5568 silc_rng_[global]_add_noise which can be used to add more
5571 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5573 * Do not parse packets with different timeout when protocol
5574 is active -> may cause problem with rekey. Affected file
5577 * When server receives signoff notify it must not create
5578 new channel key if the client is on any channels since the
5579 sender of the signoff notify will create it.
5581 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5583 * Added printing of error messages during SKE protocol from the
5584 failure packet sent by server during SKE. Affected file
5587 * Removed the client's failure_callback handling with timeout
5588 and handle it immediately when received.
5590 * The SKE library returned wrong type in SUCCESS and FAILURE
5591 packets. They must be 32 bit MSB not 16 bit MSB.
5593 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5595 * Ok, rewrote the logic of the re-key and now it seems to work.
5596 I tested it on high traffic with frequent re-keys without
5597 problems. Added hmac_receive (and renamed hmac to hmac_send)
5598 in SilcClientConnection in lib/silcclient/client.h and
5599 in SilcIDListData in silcd/idlist.h. Also, removed the
5600 SilcPacketParserContext's cipher and hmac fields as they are
5601 not needed anymore and actually caused some problems when
5602 the ciphers and hmac's changed underneath the packet parser.
5604 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5606 * If re-key protocol is active then process the incoming packets
5607 synchronously since we must assure that icoming packets encrypted
5608 with the old key is processed before the new keys is set to
5609 use. This is true other packets than for REKEY packets.
5610 Affected file silcd/server.c. The same was done to client library
5611 as well, affected file lib/silcclient/client.c.
5613 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5615 * Fixed bug in client and server to accept the force send if
5616 the packet is send from silc_[server/client]_packet_process
5617 function. Otherwise the packets are never delivered, oops.
5619 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5621 * Disable force sending of packets when REKEY protocol is active.
5622 We must assure that no packet is sent directly when rekey is
5623 performed. All packets must be sent through packet queue.
5624 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
5625 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
5626 function is silc_[server/client]_packet_send_real to check
5629 * Replaced the SIM paths from example config files to
5630 /usr/local/modules. Also, make install creates now
5631 /usr/local/silc/logs directory to hold all the SILC server
5634 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5636 * Made the configure.in.pre work on Solaris. Patch by salo.
5638 * Made all ciphers compatible with non-x86 machines. Defined
5639 CBC mode macros into lib/silccrypt/ciphers_def.h.
5641 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5643 * Fixed the make install.
5645 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5647 * When MAC computation fails the silc_packet_decrypt returned 0
5648 even though it was supposed to return -1. Fixed this. The
5649 affected file is lib/silccore/silcpacket.c.
5651 * Do not replace the config files in /etc/silc (in make install)
5652 if they already exist. Affected file ./Makefile.am.
5654 * Do not send re-key packets immediately but through packet queue.
5655 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
5657 * Changed silc_net_check_host_by_sock to return FALSE if the
5658 IP/DNS could not be resolved. Though, it returns the IP address
5659 now even if it could not resolve it (but returns also FALSE).
5660 Affected file lib/silcutil/silcnet.[ch].
5662 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5664 * Added silc_pkcs_decode_identifier to decode the public key's
5665 identifier. Affected file lib/silccrypt/silpkcs.[ch].
5666 Added also silc_pkcs_free_identifier. Added also new context
5667 SilcPublicKeyIdentifier.
5669 * Added -S option to the silc client. It is used to dump the
5670 contents of the specified public key file.
5672 * Changed the PKCS api to return the public key length when
5673 setting the public key.
5675 * Fixed a fatal bug in the public and private key file loading.
5676 Affected file lib/silccrypt/silcpkcs.c.
5678 * Execute the packet parsing for client with zero (0) timeout
5679 if the protocol is active. Affected file silcd/server.c.
5681 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5683 * Made the key generation options to the silcd program. Added
5684 -C option, equivalent to client's option.
5686 * Added new [ServerKeys] config section to the server. It
5687 configures the server's public and private key.
5689 * Defined generic Public Key Payload into the protocol
5690 specification to send specific type of public keys and
5693 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
5694 public key or certificate.
5696 * Implemented the GETKEY command to the server and to the
5697 client library and on user interface.
5699 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5701 * Made preliminary `make install' work.
5703 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5705 * Added SilcServerRekey context into silcd/idlist.h.
5707 * Added the PFS support as defined in the specification to the
5708 SKE protocol. Affected files lib/silcske/*.c.
5710 * Added `ske_group' field to the SilcServerRekey context to hold
5711 the number of the SKE group that is used with PFS in re-key.
5712 Affected file silcd/idlist.h.
5714 * Added PFS re-key support to the server. Affected file is
5717 * Added silc_protocol_cancel to cancel execution of the next
5718 state of the protocol. Affected file is
5719 lib/silccore/silcprotocol.[ch].
5721 * Added the re-key support with and without PFS to the client
5722 library. Re-key is performed once in an hour, by default.
5724 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
5725 Added silc_client_rekey_callback and silc_client_rekey_final.
5726 Affected files are lib/silcclient/protocol.[ch] and
5727 lib/silcclient/client.[ch].
5729 * Removed the `hmac_key' and `hmac_key_len' fields from the
5730 SilcClientConnection structure; not needed. Affected file is
5731 lib/silcclient/client.h.
5735 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5737 * Do not ask whether user wants to use the negotiated private key
5738 for private messages, just use it. Affected file is
5739 silc/local_command.c.
5741 * Added `send_enc_key' and `enc_key_len' fields to the
5742 SilcIDListData structure since they are needed in the re-key
5743 phase. Affected file is silcd/idlist.[ch].
5745 * Implemented the simple re-key protocol into the server.
5746 Affected files silcd/server.c and silcd/protocol.[ch]. The
5747 re-key will be performed once in an hour, by default.
5749 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
5750 Added silc_server_rekey, silc_server_rekey_callback and
5751 silc_server_rekey_final.
5753 * Removed Tunneled flag from the protocol. Updated the code
5754 and the specifications.
5756 * Adde `pfs' field to the SilcIDListData to indicate whether
5757 the PFS is to be performed in the re-key. Affected file is
5760 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5762 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
5763 int64 of at least the xintXX size. If void * is less that 4
5764 bytes uint32 * will be used. Defined bool as boolean.
5766 * Changed _ALL_ unsigned long and unsigned int to uint32,
5767 unsgined short to uint16 in the source tree.
5769 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
5770 not handle clients that has entry->data.registered == FALSE.
5771 They are not in the network anymore. Affected file is
5774 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5776 * Implemented the sending of the SERVER_SIGNOFF notify in the
5777 server. Affected file is silcd/server.c.
5779 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
5780 Added also silc_notify_payload_encode_args into the
5781 lib/silccore/silcnotify.[ch].
5783 * Implemented ther SERVER_SIGNOFF notify handling in the server.
5784 Affected file silcd/packet_receive.c.
5786 * Implemented the SERVER_SIGNOFF notify handling in the client
5787 library. Affected file lib/silcclient/client_notify.c. Also,
5788 implemnted the printing of the SERVER_SIGNOFF info to the
5789 application. Affected file silc/client_ops.c.
5791 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
5792 if the deleting was successful. Affected file silcd/idlist.[ch].
5794 * Added support for public key authentication in the connection
5795 authentication protocol in the client library. Affected file
5796 lib/silcclient/protocol.c.
5798 * Changed the server's silc_idlist_get_clients_by_* interface
5799 to support already allocated array so that new entries may be
5800 added to pre-allocated array. Affected file silcd/idlist.[ch].
5801 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
5802 and command replies.
5804 * All command reply functions in the server now calls the
5805 pending command callback even if error occured. This way the
5806 error will be delivered to the client as well. Affected files
5807 silcd/command.c and silcd/command_reply.c.
5809 * Fixed INFO command to return local server's info if no server
5810 was provided. Affected file lib/silcclient/command.c.
5812 * Removed RESTART command for good. Updated the code and the
5815 * Rewrote parts of the task system. It is a bit simpler now.
5816 Removed unsued task priorities. The affected files are
5817 lib/silcutil/silctask.[ch].
5819 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5821 * Moved the USERS printing from the library to the application.
5822 Affected files lib/silcclient/command.c and silc/client_ops.c.
5824 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5828 * Added channel key re-key support. The re-key is perfomed
5829 only by the router and is done once in an hour. Added `rekey'
5830 field to the SilcChannelEntry in the server. Affected files
5831 silcd/server.c and silcd/idlist.h.
5833 * Added silc_task_unregister_by_context into the file
5834 lib/silcutil/silctask.[ch].
5836 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5838 * Added SILC_UMODE_GONE mode to indicate when the client is not
5839 present in the SILC network. Added also support to the local
5840 command AWAY that will set this mode. Added support of showing
5841 "xxx is gone" in WHOIS command. The USERS command shows the
5842 gone status as well.
5844 * Fixed setting server and router operator privileges in the
5845 server's UMODE command. Affected file silcd/command.c.
5847 * Merged the SKE KE1 and KE2 payloads into one payload. The
5848 new KE payload is equivalent to the old KE2 payload.
5850 Cleaned up the SKE Start Payload parsing. It now uses the
5851 simple buffer unformatting to do the parsing. A lot faster
5854 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
5855 to the SKE that is used to indicate whether both of the SKE
5856 parties should perform authentication. By default only the
5857 responder performs authentication. By setting this flag also
5858 the initiator must do authentication. By default it is unset
5859 since in normal SKE case, client to server connection, only
5860 the responder should do authentication. When doing SKE between
5861 two clients both should perform authentication. Updated the
5862 code and the protocol specs.
5864 * A little fix to IDENTIFY command in the server. Search the
5865 client first by hash not nickname. Affected file is
5868 * Fixed the silc_client_close_connection to support closing
5869 the client to client connections wihtout deleting too much
5870 data. Affected file lib/silcclient/client.c.
5872 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
5873 are received if protocol used to be active but is not anymore
5874 the application would crash due to NULL pointer dereference.
5875 Affected files silcd/server.c and lib/silcclient/client.c.
5877 * Added `hash' field to the SilcClientConnection to include
5878 the hash function negotiated in the SKE protocol.
5880 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
5881 to set the channel founder authentication data. A client can
5882 claim the founder rights later by providing the authentication
5883 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
5884 This way the channel founder can regain the channel founder
5885 privileges even it is left the channel. This works only on
5886 local server and the client must be connected to the same
5887 server to be able to regain the founder rights. Updated the
5888 protocol specs accordingly.
5890 Added support to the CMODE command in the client to set the
5891 founder auth data. Read the README to see how to set it.
5893 Added support to the CUMODE command to claim the founder
5894 rights. Read the README to see how to do it.
5896 Added support for the founder authentication to the Channel
5897 Entry in the server. Affected file silcd/idlist.h.
5899 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
5900 server's CMODE command. Affected file silcd/command.c.
5902 * Added the following new functions into lib/silccore/silcauth.[ch]:
5903 silc_auth_get_method and silc_auth_get_data.
5905 * The server now saves the remote hosts public key to the
5906 SilcIDListData pointer. Affected file silcd/protocol.c.
5908 * The normal server now does not remove the channel entry from
5909 the cache if the founder authentication data is set. It used
5910 to remove it if the founder was the last one on the channel on
5911 the server and left the channel. The auth data is saved and
5912 if the channel is re-joined later the old entry is used with
5913 the old auth data. Affected files silcd/command_reply.c and
5916 * Removed the `pkcs' field from the SilcIDListData structure
5917 in the server; it is not used. Affected file silcd/idlist.h.
5919 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5921 * Fixed packet processing on slow links. Partial packets were
5922 never re-processed because the incoming data buffer was cleared
5923 by the application. Application must not directly clear the
5924 sock->inbuf, the packet processing routines handle it. Fixed
5925 this in client library and in server.
5927 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5929 * Fixed the WHOIS and IDENTIFY send reply function to really
5930 check whether to send list or just one entry. Affected file
5933 * Cleaned up the LEAVE command's channel key distribution. The
5934 affected file silcd/command.c.
5936 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
5937 can enforce the channel mode as well. In that case the ID
5938 includes the ID of the server. The code now enforces the
5939 mode change if the router have different mode than the server.
5941 * The notify client operation with CMODE_CHANGE notify can now
5942 return NULL client_entry pointer if the CMODE was not changed
5943 by client. Application must check for this.
5945 * Added <Server ID> argument to INFO command to support server
5946 info fetching by Server ID.
5948 * Added silc_server_announce_get_channel_users to get assembled
5949 packets of channel users of the specified channel. Affected
5950 file silcd/server.[ch].
5952 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
5953 was freed underneath the ID Cache.
5955 * Re-announce clients when the server received CHANNEL_CHANGE
5956 notify from the router. Affected file silcd/packet_send.c.
5958 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5960 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
5961 crashed since it did not handle the fact that there is no cipher
5962 called "3" and didn't check the error condition. Now fixed.
5964 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
5965 flag. It can be used to send message requests.
5967 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5969 * Implemented the RESTART command in the client.
5971 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
5972 notice type messages. Added notice printing to the user
5975 * The channel keys are not re-generated if the channel's mode
5976 is PRIVKEY, ie private key on the channel exists. Affected
5977 files silcd/server.c and silcd/command.c.
5979 * Fixed a little bug in channel message delivery when channel
5980 private keys are set in the server. Affected file is
5981 silcd/packet_send.c.
5983 * Changed the setting on channel->on_channel = TRUE from the
5984 silc_client_save_channel_key to the JOIN command reply. The
5985 key payload is not received if the private channel key is set.
5986 Affected file lib/silcclient/command_reply.c and the
5987 lib/silcclient/client_channel.c.
5989 * When the CMODE_CHANGE notify is sent and the channel private
5990 key mode is removed the channel key must be re-generated in
5991 other cells as well. Added this support for the router in the
5992 silcd/packet_receive.c.
5994 * Added new local command NOTICE to send notice message on
5995 channel. Affected file silc/local_command.[ch].
5997 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5999 * Added new local command ME to the client. It is used to send
6000 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
6001 some action. Affected file silc/local_command.[ch].
6003 * Changed channel_message and private_message client operations
6004 to deliver the message flags to the application. Added also
6005 the `flags' arguments to the silc_client_send_channel_message
6006 and silc_client_send_private_message functions. Affected file
6009 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6011 * Redefined the Private Message Payload to support private message
6012 keys and to support the new private message flags. Updated
6013 the protocol specs. Flags makes it possible to have for example
6014 CTCP style messages.
6016 * Added new type SilcPrivateMessagePayload and defined an API
6017 for it in the lib/silcclient/silcprivate.[ch].
6019 * Tested private message private keys successfully. Tested the
6020 private message key set, unset and list commands with the new
6023 * Redefined the Channel Message Payload to include the channel
6024 message flags (equal with private message flags) to support
6025 for example CTCP style messages.
6027 * Defined some of the message (for channel and private message)
6028 flags. Updated the protocol specs and added the flags to the
6029 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
6031 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6033 * Added SilcKeyAgreementStatus type to the key agreement routines
6034 to indicate the current status and error if one occured.
6035 The status types are defined in the lib/silcclient/silcapi.h.
6037 * Added new local command KEY that is used to set and unset private
6038 keys for channels, set and unset private keys for private messages
6039 with remote clients and to send key agreement requests and
6040 negotiate the key agreement protocol with remote client. The
6041 key agreement is supported only to negotiate private message keys,
6042 it currently cannot be used to negotiate private keys for channels,
6043 as it is not convenient for that purpose.
6045 * Fixed a minor pending callback setting bug in the function
6046 silc_client_get_client_by_id_resolve, now the function works.
6047 Affected file lib/silcclient/idlist.c.
6049 * Added function silc_net_get_local_port to get local bound
6050 port by socket. Added to lib/silcutil/silcnet.[ch].
6052 * Added `sockets' and `sockets_count' fields to the SilcClient
6053 object. They hold the sockets of the listenning sockets in
6054 the client. Listenning sockets may be for example the key
6055 agreement server. Affected file lib/silcclient/client.[ch].
6056 Added functions the silc_client_add_socket and the
6057 silc_client_del_socket. They are exported to the application
6060 * Added ~./silc/clientkeys to support other client's public keys.
6062 * Renamed verify_server_key client operation to verify_public_key
6063 and added one argument to indicate the type of the connection
6064 (server, client etc.).
6066 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6068 * Added silc_server_connection_auth_request to handle the
6069 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
6070 silcd/packet_receive.[ch].
6072 * Added silc_server_send_connection_auth_request into the
6073 silcd/packet_send.c to send the connection auth request packet.
6075 * Cleaned up the silcd/protocol.c a bit and fixed some memory
6078 * Fixed the public key authentication in responder side in the
6079 server. The `auth_data' pointer includes the SilcPublicKey
6080 not the path to the public key. Affected file silcd/protocol.c.
6082 * Implemented the public key authentication in the initiator side
6083 in the server. Affected file silcd/protocol.c.
6085 * Removed the [RedirectClient] config section from the server
6086 configuration. Is not needed and I don't want to implement it.
6088 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6090 * Cleaned up the CMODE command in the server. It now works
6091 correctly and supports all the modes defined in the protocol.
6092 Affected file is silcd/command.c.
6094 * Added `hmac_name' field to the SilcChannelEntry in the server
6095 to hold the default HMAC of the channel. It can be set when
6096 creating the channel (with JOIN command). Affected files
6099 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
6100 type to indicate the change of the current cipher and hmac
6101 on the channel. Client can safely ignore the <cipher> argument
6102 (if it chooses to do so) since the CHANNEL_KEY packet will
6103 force the channel key change anyway. The <hmac> argument is
6104 important since the client is responsible of setting the new
6105 HMAC and the hmac key into use.
6107 * Fixed the CMODE command in the client library as well.
6109 * Tested CMODE command in router environment successfully.
6111 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6113 * Show the version of the remote client (or server) when connecting
6114 to the server. It is logged to the log file. Affected file
6115 is silcd/protocol.c.
6117 * Fixed the KILLED notify handling in the client library. The
6118 client must be removed from all channels when receiving the
6121 Also, do not remove the client entry when giving the KILL
6122 command but when the KILLED notify is received.
6124 * Removed silc_idlist_find_client_by_nickname from the server.
6125 Not needed anymore. Affected files silcd/idlist.[ch].
6127 * Implemented the CHANNEL_CHANGE notify type handling to the
6128 server. Affected file silcd/server.c.
6132 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6134 * Added silc_server_send_notify_invite to send the INVITE
6135 notify between routers.
6137 * Implemented the INVITE command correctly to the server.
6139 * Implemented the INVITE notify type handling in the server.
6141 * Implemented the INVITE command to the client library and on the
6144 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6146 * Added function silc_server_get_client_resolve to find the
6147 client entry by ID from all ID lists and then resolve it
6148 (using WHOIS) if it cannot be found. Affected file is
6151 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6153 * Implemented the BAN command to the client library.
6155 * The JOIN command in the server now checks the invite list
6158 * Changed the silc_command_reply_payload_encode_va and the
6159 silc_command_payload_encode_va to support that if argument is
6160 NULL it ignores and checks the next argument. Affected file
6161 lib/silccore/silccommand.c.
6163 * Added silc_server_send_notify_ban to send the BAN notify
6164 type between routers.
6166 * Chaned the silc_notify_payload_encode to support that if
6167 argument is NULL it ignores and checks the next argument.
6168 Affected file lib/silccore/silcnotify.c.
6170 * Tested ban lists in router environment successfully.
6172 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6174 * Implemented BAN command to the server, in silcd/command.[ch].
6176 * Removed the BAN and INVITE_LIST modes from the CMODE command
6179 * Added function silc_string_match to regex match two strings.
6180 Affected files lib/silcutil/silcutil.[ch].
6182 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6184 * Redefined parts of the SilcChannelEntry in the server to support
6185 the new ban and invite lists.
6187 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6189 * Redefined the INVITE command. The same command can be used to
6190 invite individuals to the channel but also to manage the invite
6191 list of the channel (to add to and remove from the invite list).
6192 Updated the protocol specs.
6194 * Added new command SILC_COMMAND_BAN that can be used to manage
6195 the ban list of the channel. Updated the protocol specs.
6197 * Removed the channel modes: the SILC_CMODE_BAN and the
6198 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
6199 in the CMODE command. The equivalent features are now available
6200 using INVITE and BAN commands. Updated the protocol specs.
6202 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
6203 in the network about change in the current ban list. The notify
6204 type is not used by the client.
6206 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
6207 support the invite lists.
6209 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6211 * Added new function silc_string_regexify that converts string
6212 including wildcard characters into regex string that can
6213 be used by the GNU regex library. Added into the file
6214 lib/silcutil/silcutil.[ch].
6216 Added silc_string_regex_combine to combine to regex strings
6217 into one so that they can be used as one regex string by
6218 the GNU regex library. Added into the file
6219 lib/silcutil/silcutil.[ch].
6221 Added silc_string_regex_match to match two strings. It returns
6222 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
6224 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6226 * Imported GNU regex to the soruce tree into lib/contrib.
6227 Fixed some compiler warning from the regex.c.
6229 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6231 * Fixed MOTD command in the server to work in router environment.
6233 * Fixed the MOTD command in the client library to support
6234 the server argument in the command.
6236 * Added `nickname_len' argument to the silc_idlist_add_client
6237 in the server, as the `nickname' argument may be binary data
6240 * Added silc_idlist_get_channels to return all channels from
6243 * Implemented LIST command to the server. Affected file is
6246 * Implemented the LIST command to the client library and on the
6249 * Added [<user count>] argument to the LIST command reply.
6250 With private channels the user count is not shown.
6252 * Updated TODO and README.
6254 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6256 * The client entry's data.registered must be TRUE even with
6257 global client entry on global client list. The data.registered
6258 is used to check whether the client is anymore in the network,
6259 for example with WHOWAS command so it must be valid.
6261 * Fixed the WHOWAS command in the server. It now actually works
6262 in router environment. Added function into silcd/command_reply.c
6263 silc_server_command_reply_whowas_save.
6265 * Added silc_idlist_purge function to the silcd/idlist.c
6266 to periodically purge the ID Cache.
6268 * Fixed INFO command in the server. It works now in router
6269 environment. Added <server name> argument to the INFO command
6270 reply. Updated the protocol specs.
6272 * Fixed minor bug in silc_idcache_purge to not purge if the
6273 expire value is zero.
6275 * Fixed various bugs in WHOIS and IDENTIFY command handling as
6276 they were buggy because of the WHOWAS information.
6278 * Fixed local command MSG to handle the async resolving of
6279 the remote client properly. It used to fail the first MSG.
6280 Affected file silc/local_command.c.
6282 * Added `data_len' field to SilcIDCache context.
6284 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6286 * Update TODO. Todo in commands in the server.
6288 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6290 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
6291 used by routers as broadcast packet to inform other routers
6292 about the changed user mode.
6294 Implemented the notify handling in the server. Affected file is
6295 silcd/packet_receive.c. Added the function
6296 silc_server_send_notify_umode to the silcd/packet_send.[ch].
6298 * Added new generic Channel Payload and deprecated the New Channel
6299 Payload. The New Channel Payload is now the generic Channel
6302 * Added new argument `mode' to the silc_server_send_new_channel
6303 as it is required in the Channel Payload now.
6305 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
6306 and created a new and real SilChannelPayload to represent the
6307 new generic Channel Payload. Implemented the encode/decode
6308 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
6310 * Added silc_server_get_client_channel_list to return the list
6311 of channels the client has joined for WHOIS command reply.
6312 Affected file silcd/server.[ch].
6314 * Implemented the channel list sending in the WHOIS command reply
6315 in server and in the client.
6317 Implemented the channel list displaying on the user interface
6318 as well. Affected file silc/client_ops.c.
6320 * Added silc_channel_payload_parse_list to parse list of Channel
6321 Payloads. It returns SilcDList list of SilcChannelPayloads.
6322 Client for example can use this function to parse the list of
6323 channels it receives in the WHOIS command reply. The caller
6324 must free the list by calling silc_channel_payload_list_free.
6325 Affected files lib/silccore/silcchannel.[ch].
6327 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6329 * Added one new argument <user mode> to the WHOIS command reply
6330 to return the mode of the user in SILC. Updated the protocol
6333 Implemented it to the server and client.
6335 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6337 * Fixed the mode printing on the user interface on joining.
6338 Affected file silc/client_ops.c.
6340 * Implemented the UMODE command and user modes in general to the
6341 client library and to the user interface.
6343 * Implemented the UMODE command to the server.
6345 * The server now sends UNKNOWN_COMMAND error status if client sends
6346 unknown command. Affected file silcd/command.c.
6348 * All server commands now handle the command identifier the right
6349 way when sending the command reply to the client. The client can
6350 use to identify the command replies with the identifier.
6352 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6354 * Added silc_server_get_client_route to resolve the route to
6355 the client indicated by the client ID. Affected file is
6358 * Added silc_server_relay_packet as general function to relay
6359 packet to arbitrary destination. This deprecates functions
6360 like _send_private_message_key, _relay_notify etc. Affected
6361 file is silcd/packet_send.[ch].
6363 Removed silc_server_send_key_agreement,
6364 silc_server_send_private_message_key and
6365 silc_server_packet_relay_notify functions from the file
6366 silcd/packet_send.[ch].
6370 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
6371 server. Affected file silcd/packet_receive.[ch].
6373 * Implemented the KILL command to the client. Implemented the
6374 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
6375 Affected files lib/silcclient/command[_reply].c and
6376 lib/silcclient/client_notify.c. Implemented the KILL notify
6377 printing in the user inteface.
6379 * Fixed a lot silc_parse_nick memory leaks from the client
6380 library in the file lib/silcclient/command.c.
6382 * Changed the silc_server_send_notify_on_channels's `sender'
6383 argument from SilcSocketConnection to SilcClientEntry to
6384 check the sender as entry and not as connection object and not
6385 to send to the client provided as argument. The affected file
6386 is silcd/packet_send.[ch].
6388 * The notify packets that are destined directly to the client used
6389 to not to be processed by the server. Now changed that and the
6390 server processes all notify packets. After relaying the packet
6391 to the client the notify packet is processed in the server.
6393 * The silc_server_free_client_data now checks whether there is
6394 pending outgoing traffic for the client and purges the data to
6395 the network before removing the client entry.
6397 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6399 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
6400 an client is killed from the SILC Network. Updated the protocol
6403 Added new function silc_server_send_notify_killed to the
6404 silcd/packet_send.[ch].
6406 * Added function silc_server_packet_relay_notify to relay notify
6407 packets that are destined directly to a client. In this case
6408 the server does not process the notify packets but merely relays
6409 it to the client. Affected file silcd/packet_send.[ch].
6411 Added also silc_server_packet_process_relay_notify to check
6412 whereto relay the notify. Affected file is
6413 silcd/packet_receive.[ch].
6415 * Implemented the KILL command to the server.
6419 * Added the backup schema desgined last fall to the protocol
6420 specs for everyone to see. The specification is in the
6421 *-spec-xx.txt draft and the packet type definitions for the
6422 backup routers is in *-pp-xx.txt draft. Thusly, added also
6423 new packet type SILC_PACKET_CELL_ROUTERS.
6425 * A big security problem in the implementation discovered. The
6426 signoff of an client did not cause new channel key generation
6427 which it of course should've done. The channel keys must be
6428 always re-generated when client leaves (or signoffs) the channel.
6429 The silc_server_remove_from_channels funtion now handles
6430 the channel key re-generation.
6432 * Added `sender' argument to the silc_server_send_notify_on_channels
6433 to not to send the client provided as argument. Affected file
6434 silcd/packet_send.[ch].
6436 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6438 * Implemented OPER and SILCOPER commands into the server and
6441 * Added silc_auth_verify and silc_auth_verify_data to verify
6442 the authentication directly from the authentication payload.
6443 It supports verifying both passphrase and public key based
6444 authentication. Affected file lib/silccore/silcauth.[ch].
6446 * Added `hash' field to the SilcIDListData structure. It is the
6447 hash negotiated in the SKE protocol. Affected file is
6450 * Slight redesigning of the SilcAuthPayload handling routines.
6451 Do not send SilcPKCS but SilcPublicKey as argument.
6453 * Implemented the public key authentication support to the
6454 serverconfig. The public key is loaded from the provided path
6455 and saved as authentication data to void * pointer. Thus,
6456 changed the unsigned char *auth_data to void *auth_data;
6458 * Fixed SHUTDOWN command to send the reply before the server
6459 is shutdown. :) Affected file silcd/command.c.
6461 * Fixed fatal bug in CONNECT command. The hostname was invalid
6462 memory and server crashed. Affected file silcd/command.c.
6464 * Fixed fatal bug in CLOSE command. The server_entry became
6465 invalid but was referenced later in the command. Affected file
6468 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6470 * Fixed fatal bug in failure packet handling. Server ignored
6471 the failure and thus crashed when it came.
6475 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6477 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
6478 that the command may be executed only once in (about) 2 seconds.
6479 The old SILC_CF_LAG flag is same but allows command bursts up
6480 to five before limiting.
6482 Added the support for CF_LAG and CF_LAG_STRICT flags to the
6483 server code. Various commands now includes the CF_LAG_STRICT
6484 flag to disallow any kind of miss-use of the command.
6486 * Fixed the silc_buffer_unformat to not to allocate any data
6487 if the length of the data is zero. It used to allocate the
6488 length + 1. Affected file lib/silcutil/silcbuffmt.c.
6490 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6492 * Changed the format of AdminConnection configuration section
6493 in the server. Added username of the admin to the format.
6494 Affected files silcd/serverconfig.[ch].
6496 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
6497 to return admin configuration data by host, username and/or
6500 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6502 * Implemented WHOWAS command to the server. Added the functions:
6504 silc_server_command_whowas_parse,
6505 silc_server_command_whowas_send_reply,
6506 silc_server_command_whowas_from_client and
6507 silc_server_command_whowas_from_server
6509 * Added <Client ID> argument to the WHOWAS command reply. Updated
6510 the protocol specs accordingly.
6512 * Implemented WHOWAS command and command_reply to the client
6515 Implemented the WHOWAS printing on the user interface.
6517 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6519 * Added new argument to the WHOWAS command reply, the real name.
6520 It is an optional argument. Updated the protocol specs.
6522 * Added SilcIDCacheDestructor callback that is registered when
6523 the SilcIDCache is allocated. The callback is called when
6524 an cache entry in the ID Cache expires, or is purged from the
6525 cache. Added into lib/silccore/idcache.[ch].
6527 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
6528 to destruct the client entries when the cache entry expires.
6529 Other ID Cache's in server and in the client library ignores
6532 * If the ID Cache entry's `expire' field is zero then the entry
6533 never expires. Added boolean `expire' argument to the
6534 silc_idcache_add function in the lib/silccore/idcache.[ch].
6535 If it is TRUE the default expiry value is used.
6537 * Added silc_server_free_client_data_timeout that is registered
6538 when client disconnects. By default for 5 minutes we preserve
6539 the client entry for history - for WHOWAS command.
6541 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6543 * Added support to the server to enforce that commands are not
6544 executed more than once in 2 seconds. If server receives
6545 commands from client more frequently, timeout is registered
6546 to process the commands. Affected file silcd/command.c.
6547 Added new function silc_server_command_process_timeout.
6549 * Changed NICK_NOTIFY handling in client library to check that
6550 if the client's nickname was changed, so there is no need to
6551 resolve anything from the server.
6553 * Removed error printing from the WHOIS and IDENTIFY commands.
6554 If error occurs then it is ignored silently in the client library.
6555 The application, however, may map the received error to
6556 human readable error string. The application currently maps
6557 the NO_SUCH_NICKNAME error to string.
6559 * Made the command status message public to the application. Moved
6560 them from lib/silcclient/command_reply.c to
6561 lib/silcclient/command_reply.h. The application can map the
6562 received command status to the string with the
6563 silc_client_command_status_message function.
6565 * Added check to the server to check that client's ID is same
6566 as the Source ID in the packet the client sent. They must
6569 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6571 * Added dist-bzip hook to the Makefile.am to make bzip2
6572 compressed distributions.
6574 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6576 * Server now enforces the maximum length for the nickname and
6577 the channel as protocol specification dictates. 128 bytes for
6578 nickname and 256 bytes for channel name.
6580 * Moved the WHOIS printing to the application. The client libary
6581 does not print out the WHOIS information anymore, the application
6582 must do it. Renamed silc_client_command_reply_whois_print to
6583 the silc_client_command_reply_whois_save.
6585 The client's idle time is also sent to the application now, and
6586 the idle is shown on screen.
6588 * Added silc_client_command_reply_identify_save to save the
6589 received IDENTIFY entries.
6591 * Do not check for channel private keys in message sending and
6592 reception if the channel does not have the PRIVKEY mode set.
6593 Affected file lib/silclient/client_channel.c.
6595 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6597 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
6598 just surfaced after chaning the JOIN procedure.
6600 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6602 * Added silc_client_get_clients_by_list to get client entries
6603 from Client ID list, that is returned for example by JOIN
6604 and USERS command replies. The application should use this
6605 function for example when JOIN command reply is received to
6606 resolve the clients already on the channel (library does not
6607 do that anymore as USERS command reply is not used in the JOIN
6608 procedure anymore). Affected files lib/silcclient/silcapi.h and
6609 lib/silcclient/idlist.c.
6611 * JOIN command reply and USERS command reply returns now SilcBuffer
6612 pointers instead of unsigned char pointers when returning
6613 the client list and mode list.
6615 * Added <Client ID> argument to the JOIN command reply, mainly
6616 for the server to identify for which client the command was
6617 originally sent. Updated protocol specs accordingly.
6619 * Added SilcDlist private_key pointer to the SilcChannelEntry
6620 in the client to support the channel private keys. Affected
6621 file is lib/silcclient/idlist.h.
6623 * Added SilcChannelPrivateKey argument to the function
6624 silc_client_send_channel_message so that application can choose
6625 to use specific private ke if it wants to. If it is not provided,
6626 the normal channel key is used, unless private keys are set.
6627 In this case the first (key that was added first) is used
6628 as the encryption key.
6630 * Implemented the support for channel private key handling.
6631 Implemented the following functions:
6633 silc_client_add_channel_private_key,
6634 silc_client_del_channel_private_keys,
6635 silc_client_del_channel_private_key,
6636 silc_client_list_channel_private_keys and
6637 silc_client_free_channel_private_keys
6639 Affected file lib/silcclient/client_channel.c.
6641 * Added the support for the private keys in the channel message
6642 sending and encryption and in the message reception and
6643 decryption. Affected funtions are
6644 silc_client_send_channel_message and silc_client_channel_message.
6646 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6648 * Added SKE's key verify callback to the client library's
6649 KE protocol context. Affected files lib/silcclient/protocol.[ch].
6651 * Removed the statement that server (or router) must send USERS
6652 command reply when joining to the channel so that the client
6653 knows who are on the channel. Instead, the client list and
6654 client's mode list is now sent in the JOIN command reply to the
6655 client who joined channel. This is better solution.
6657 * Added function silc_server_get_users_on_channel and function
6658 silc_server_save_users_on_channel to the silcd/server.[ch].
6660 * Removed function silc_server_command_send_users from the
6663 * Do not show topic on the client library anymore. The topic is
6664 sent in the command reply notify to the application and the
6665 application must show the topic now.
6667 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6669 * Added client searching by nickname hash into the IDENTIFY and
6670 WHOIS commands in the server as they were clearly missing from
6671 them. Affected file is silcd/command.c.
6673 * Fixed a bug in private message receiving in the client library.
6674 The remote ID was freed and it wasn't supposed, now it is
6677 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6679 * Minor fix to the channel payload; allocate the data area, as it
6680 needs to be of specific length.
6682 * If the key agreement port is zero then the operating
6683 system will define the bound port. Affected files are
6684 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
6686 * Added new function silc_channel_payload_decrypt into the file
6687 lib/silccore/silcchannel.[ch].
6689 * Moved the channel message etc, check from silc_packet_decrypt
6690 to applications. The library calls now a generic
6691 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
6692 when the packet is either normal or special. This was done to
6693 allow more wide range of checking that was not allowed when
6694 the code was in library. Now applications can do virtually any
6695 checks to the packet and return to the library the decision how
6696 the packet should be processed. Affected files are
6697 lib/silccore/silcpacket.[ch].
6699 Added silc_server_packet_decrypt_check to the server and
6700 silc_client_packet_decrypt_check to the client library.
6702 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
6703 to send with specified source and destination information.
6705 * Channel message delivery between routers was broken after the
6706 channel key distribution was fixed earlier. The channel key
6707 was used be to distributed to other routers as well which is not
6708 allowed by the protocol. Now this is fixed and channel keys
6709 really are cell specific and the channel message delivery between
6710 routers comply with the protocol specification.
6712 * Fixed various commands in server to check also the global list
6713 for the channel entry and not just the local list. The affected
6714 file silcd/command.c.
6716 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6718 * Added assert()s to buffer formatting and unformatting routines
6719 to assert (if --enable-debug) when error occurs. Affected
6720 file: lib/silcutil/silcbuffmt.c.
6722 * Changed to auto-reconnect to check whether the remote host is
6723 router and register the re-connect timeout if it is. It used
6724 to check that whether we are normal server, but router must do
6725 auto-reconnect with another router as well. Affected file
6728 * Removed the [<key len>] option from CMODE command as the cipher
6729 name decides the key length, nowadays. See the defined ciphers
6730 from the protocol specification.
6732 * Added [<hmac>] option to the CMODE command to define the HMAC
6733 for the channel. Added SILC_CMODE_HMAC channel mode.
6735 * Added [<hmac>] option for the JOIN command so that user can
6736 select which HMAC is used to compute the MACs of the channel
6739 * Added Hmac field to the Channel Message Payload. The integrity
6740 of plaintext channel messages are now protected by computing
6741 MAC of the message and attaching the MAC to the payload. The
6742 MAC is encrypted. Now, it is clear that this causes some
6743 overhead to the size of the packet but rationale for this is that
6744 now the receiver can verify whether the channel message decrypted
6745 correctly and also when private keys are set for the channel the
6746 receiver can decrypt the packet with several keys and check from
6747 the MAC which key decrypted the message correctly.
6749 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
6750 lib/silccrypt/silccipher.[ch].
6752 * Added silc_hash_len to return the digest length into the
6753 lib/silcrypt/silchash.[ch].
6755 * Rewrote parts of Silc Channel Payload interface in the
6756 lib/silccore/silcchannel.[ch]. The encode function now also
6757 encrypts the packet and parse function decrypts it.
6759 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6761 * Fixed a minor formatting bug in the SKE's key material processing.
6762 It actually might have processed the keys wrong way resulting
6765 * Redefined the mandatory HMAC algorithms and added new algorithms.
6766 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
6767 and hmac-md5 truncated to 96 bits. The mandatory is now
6768 hmac-sha1-96. Rest are optional (including the one that used
6769 to be mandatory). Rationale for this is that the truncated HMAC
6770 length is sufficient from security point of view and can actually
6771 make the attack against the HMAC harder. Also, the truncated
6772 HMAC causes less overhead to the packets. See the RFC2104 for
6775 * Added new [hmac] configuration section. The SKE used to use
6776 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
6777 is of course wrong. The official names that must be proposed in
6778 the SKE are the ones defined in the protocol specification
6779 (hmac-sha1-96 for example). The user can configure any hmac
6780 using any hash function configured in the [hash] section. At
6781 least, the mandatory must be configured.
6783 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
6785 * Added HMAC list to the SKE proposal list. It has now both
6786 hash algorithm list and HMAC list. This makes the protocol
6787 incompatible with previous versions. The SKE now seems to work
6788 the way it is supposed to work, for the first time actually.
6790 * Defined plain Hash algorithms to the protocol specification.
6793 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6795 * Implemented support for key agreement packets into the server.
6796 Added functions silc_server_key_agreement and
6797 silc_server_send_key_agreement. Other than these functions,
6798 server has nothing to do with this packet.
6800 * Added support for private message key packets into the server.
6801 Added functions silc_server_private_message_key and
6802 silc_server_send_private_message_key.
6806 * Changed the silc_[client|server]_protocol_ke_set_keys to be
6807 called in the protocol's final callback instead in the END
6808 protocol state. This makes a little more sense and in the same
6809 time in client we can use the same protocol routines for normal
6810 key exchange and to key agreement packet handling as well.
6812 * Added to both client's and server's KE protocol context the
6813 SilcSKEKeyMaterial pointer to save the key material. We will
6814 bring the key material to the protocol's final callback by doing
6815 this. The final callback must free the key material.
6817 * Added SKE's packet_send callback into client's KE protocol
6818 context so that the caller can choose what packet sending function
6819 is used. This way we can use different packet sending when
6820 doing normal SKE when doing key agreement packet handling (in
6821 the key agreement packet handling we do not want to encrypt
6824 * Implemented the responder side of the key agreement routines
6825 in the client. The client can now bind to specified port and
6826 accept incoming key negotiation. The key material is passed
6827 to the application after the protocol is over.
6829 * Implemented the processing of incoming Key Agreement packet
6830 in the client. Added function silc_client_key_agreement to
6833 * Implemented the intiator side of the key agreement routines
6834 in the client. The client can now initiate key agreement with
6835 another remote client. The key material is passed to the
6836 application after the protocol is over.
6838 * Created client_keyagr.c to include all the key agreement
6841 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
6842 SILC_TASK_CALLBACK except that it is not static.
6844 * Created client_notify.c and moved the Notify packet handling
6845 from the client.[ch] into that file.
6847 * Created client_prvmsg.c and moved all private message and
6848 private message key routines from the client.[ch] into that file.
6850 * Create client_channel.c and moved all channel message and
6851 channel private key routines from the client.[ch] into that file.
6853 * Changed silc_client_get_client_by_id_resolve to resolve with
6854 WHOIS command instead of IDENTIFY command, in the file
6855 lib/silclient/idlist.c.
6857 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6859 * Implemented the SKE's responder side to the Client library.
6861 * When FAILURE is received to the protocol do not trust it
6862 blindly. Register a timeout to wait whether the remote closes
6863 the connection as it should do it, only after that process the
6864 actual failure. This was changed to both client and server.
6866 * Added client_internal.h to include some of the structures
6867 there instead of client.h in lib/silcclient/.
6869 * Added function silc_task_unregister_by_callback to unregister
6870 timeouts by the callback function.
6872 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6874 * Some "Incomplete WHOIS info" errors has been appearing on the
6875 log files. Took away the entry->userinfo check from WHOIS
6876 reply sending. The entry->userinfo is now " " if client did not
6877 provide one. I thought this was fixed earlier but something
6878 is wrong still. Let's see if the error still appears.
6880 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6882 * Fixed a minor bug in the login when the channel key is
6883 re-generated in the server. It used to generate the key in
6884 wrong order and thus caused problems in the channel traffic.
6886 * Fixed a minor bug in channel key distsribution after
6887 KICK command. The key was not sent to the router even though
6890 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6892 * Added silc_ske_process_key_material_data as generic routine
6893 to process any key material as the SILC protocol dictates. The
6894 function is used by the actual SKE library but can be used by
6895 applications as well. This relates to the private message keys
6896 and the channel private keys since they must be processed the
6897 same way the normal SILC session keys. The protocol dictates
6898 this. Affected files: lib/silcske/silcske.[ch].
6900 Added also silc_ske_free_key_material to free the
6901 SilcSKEKeyMaterial structure.
6903 * Defined silc_cipher_set_key function to set the key for
6904 cipher without using the object's method function. The affected
6905 files: lib/silccrypt/silccipher.[ch].
6907 * Implemented silc silc_client_add_private_message_key,
6908 silc_client_add_private_message_key_ske,
6909 silc_client_del_private_message_key,
6910 silc_client_list_private_message_keys and
6911 silc_client_free_private_message_keys functions in the
6914 Added functions silc_client_send_private_message_key to send
6915 the Private Message Key payload and silc_client_private_message_key
6916 to handle incoming Private Message Key payload.
6918 * Added Cipher field to the Private Message Key payload to set
6919 the cipher to be used. If ignored, the default cipher defined
6920 in the SILC protocol (aes-256-cbc) is used.
6922 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6924 * Removed lib/silcclient/ops.h file.
6926 Redefined parts of the SILC Client Library API. Created new
6927 file silcapi.h that deprecates the ops.h file and defines the
6928 published Client Library API. Defined also private message key
6929 API and channel private key API into the file.
6931 This is the file that the application must include from the
6932 SILC Client Library. Other files need not be included by
6933 the application anymore.
6935 * Added new key_agreement client operation callback and also
6936 defined the Key Agreement library API for the application.
6938 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6940 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
6941 is used by clients to request key negotiation between another
6942 client in the SILC network. If the negotiation is started it
6943 is performed using the SKE protocol. The result of the
6944 negotiation, the secret key material, can be used for example
6945 as private message key.
6947 Implemented the Key Agreement payload into the files
6948 lib/silccore/silauth.[ch].
6950 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6952 * Redefined ciphers for the SILC protocol. Added some new ciphers
6953 and defined the key lengths for the algorithms. Changed the
6954 code accordingly. The default key length is now 256 bits.
6956 * Fixed SKE key distribution function silc_ske_process_key_material
6957 when the key length is more than 128 bits. The default key
6958 length in SILC is now 256 bits.
6960 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
6961 to indicate unsupported algorithm.
6963 * Renamed rijndael.c to aes.c and all functions as well.
6965 * Fixed a long standing channel key setting bug in client library.
6966 Weird that it has never surfaced before.
6968 * Fixed bug in channel deletion. If the entire channel is removed
6969 then it must also delete the references of the channel entry
6970 from the client's channel list as the client's channel entry and
6971 the channel's client entry share same memory.
6973 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6975 * Implemented CONNECT and SHUTDOWN commands in the client.
6977 * Implemented CLOSE command to the client.
6979 * Added the function silc_idlist_find_server_by_name into the
6980 files silcd/idlist.[ch].
6982 Added the function silc_idlist_find_server_by_conn into the
6983 files silcd/idlist.[ch].
6985 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6987 * DIE command was renamed to SHUTDOWN. Updated the both code
6990 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
6991 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
6993 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
6996 * Added function silc_server_create_connection function to create
6997 connection to remote router. My server implementation actually
6998 does not allow router to connect to normal server (it expects
6999 that normal server always initiates the connection to the router)
7000 so the CONNECT command is only good for connecting to another
7003 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7005 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
7006 or some other client was kicked from the channel.
7008 Implemented the handling of the notify type to both client
7011 Implemented silc_server_send_notify_kicked to send the KICKED
7012 notify. It is used to send it to the server's primary router.
7014 * Implemented the KICK command into server and client.
7016 * Added `query' argument to the silc_idlist_get_client function
7017 to indicate whether to query the client from server or not if
7020 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
7021 to indicate that the client is not channel founder.
7025 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7027 * Removed the rng context from SilcPacketContext structure and
7028 changed that the packet routine uses the Global RNG API.
7030 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7032 * Added support for quit message that client can "leave" on the
7033 channel when it quits the SILC. It is ditributed inside the
7034 SILC_NOTIFY_TYPE_SIGNOFF notify type.
7036 Added silc_server_free_client_data that will take the
7037 signoff message as argument.
7039 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
7041 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7043 * Updated parts of the protocol specification to keep it up
7046 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7048 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
7049 payloads in one packet.
7051 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
7052 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
7053 use now the new List flag.
7055 * Also deprecated the following packet types: REPLACE_ID,
7056 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
7058 * Added list support for Notify packet in server.
7060 * Added silc_server_send_notify_channel_change to send the
7061 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
7062 the silc_server_send_replace_id.
7064 * Added silc_server_send_notify_nick_change to send the
7065 NICK_CHANGE notify type. Deprecates the function
7066 silc_server_send_replace_id.
7068 * Added silc_server_send_notify_join to send the JOIN notify type.
7069 Deprecates the function silc_server_send_new_channel_user.
7071 * Added silc_server_send_notify_leave to send LEAVE notify type.
7072 Deprecates the function silc_server_send_remove_channel_user.
7074 * Added silc_server_send_notify_cmode and
7075 silc_server_send_notify_cumode to send CMODE and CUMODE notify
7076 types. Deprecates the silc_server_send_set_mode function.
7078 * Added SERVER_SIGNOFF notify type to indicate that server has
7079 quit. This means that all clients on the channel from that
7080 server will drop. This can be also used when netsplit happens.
7082 Deprecated REMOVE_ID packet type since it is not needed anymore
7085 Added silc_server_send_notify_server_signoff to send the
7086 SERVER_SIGNOFF notify type. Deprecates the function
7087 silc_server_send_remove_id.
7089 Added also silc_server_send_notify_signoff to send the
7090 SIGNOFF notify type.
7092 * Employed the PKCS #1. It is the mandatory way to do RSA in the
7093 SILC protocol from this day on. Changed the protocol
7094 specification as well.
7096 * Added silc_server_send_notify_topic_set to send TOPIC_SET
7097 notify type. It is used between routers to notify about
7098 topic changes on a channel.
7100 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
7103 * Partly updated the protocol specification to comply with the
7104 changes now made. It is still though a bit outdated.
7106 * The JOIN notify type now takes one extra argument <Channel ID>.
7107 The packet used to be destined to the channel but now the
7108 JOIN type may be sent as list thus it is impossible to
7109 destine it to any specific channel. By adding this argument
7110 it is again possible.
7112 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7114 * Added CREDITS file. The CHANGES and CREDITS file will appear
7115 in the distribution as well.
7117 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7119 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
7120 types in the server's silcd/packet_receive.c.
7122 * Implemented CMODE and CUMODE to work in router environment.
7124 * Fixed minor encoding and decoding buglet from the
7125 lib/silccore/silcmode.c.
7127 * Fixed buffer overflow from lib/silcclient/command.c in USERS
7130 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
7132 * Changed all SilcConfigServer* and silc_config_server* to
7133 SilcServerConfig* and silc_server_config*, respectively.
7136 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7138 * Associated the ID (client or server ID) to the Authentication
7139 Payload to avoid any possibility of forging. Updated the
7140 protocol specification and the code accordingly.
7142 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7144 * The RSA key length is now save to the RsaKey context in the
7145 key generation process in lib/silccrypt/rsa.c. The key length
7146 is now used to figure out the maximum size of the block allowed
7147 to be encrypted/signed.
7149 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
7150 is equivalent to the silc_mp_mp2bin but does not allocate any
7153 * Changed silc_mp_mp2bin API to take length argument. If it is
7154 non-zero then the buffer is allocated that large. If zero, then
7155 the size is approximated using silc_mp_sizeinbase, which however
7158 * Created Global RNG API which is global RNG that application can
7159 initialize. After initializing, any routine anywhere in the
7160 code (including library) can use RNG without allocating a new
7161 RNG object. This was done to allow this sort of use of the
7162 RNG in code that has no chance to allocate RNG object. All
7163 applications currently allocate this and many routines in the
7164 library use this. Affected file lib/silccrypt/silcrng.[ch].
7166 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
7167 it to use the Global RNG API.
7169 * Defined Authentication Payload into protocol specification that
7170 is used during SILC session to authenticate entities. It is
7171 used for example by client to authenticate itself to the server
7172 to obtain server operator privileges.
7174 Implemented this payload into the lib/silccore/silcauth.[ch].
7175 Implemented also routines for public key based authentication
7176 as the new protocol specification dictates.
7178 Moved definitions of different authentication methods from
7179 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
7181 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
7182 silc_pkcs_verify and silc_pkcs_sign_with_hash and
7183 silc_pkcs_verify_with_hash functions into the file
7184 lib/silccrypt/silcpkcs.[ch].
7186 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7188 * The client entry's userinfo pointer must be always valid.
7189 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
7190 will fail since it requires the userinfo. Now, the userinfo
7191 is allocated as "" if actual userinfo does not exist. Actually,
7192 it must exist and it is totally Ok to drop client connections
7193 that does not announce the userinfo. However, we will make
7194 this workaround for now.
7196 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
7197 to return the remote port by socket.
7199 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7201 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
7202 SILC_SERVER_PENDING_EXEC and added an new macro
7203 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
7204 data or when error occurs while processing the pending command.
7206 Added new argument `destructor' into silc_server_command_pending
7207 and to the SilcServerCommandPending object. This destructor is
7208 now called after calling the pending callback or if error occurs
7209 immediately. If error occurs the actual pending callback won't
7210 be called at all - only the destructor. The destructor may be
7211 NULL if destructor is not needed.
7213 All this applies for client library code as well. Similar
7214 changes were made there as well for the pending commands.
7216 In the client, the application must now allocate the
7217 SilcClientCommandContext with the silc_client_command_alloc
7220 * Added reference counter to the SilcServerCommandContext. Added
7221 function silc_server_command_alloc and silc_server_command_dup
7224 Same type of functions added to the client library for the same
7227 * Removed the cmd_ident from IDListData away since it is now
7228 global for all connections. It is the command identifier used
7229 in command sending and with pending commands. The affected file
7232 * Added reference counter to the SilcSocketConnection objecet to
7233 indicate the usage count of the object. The object won't be
7234 freed untill the reference counter hits zero. Currently only
7235 server uses this, and client ignores it. The client must be
7236 set to use this too later. The affected files are
7237 lib/silccore/silcsockconn.[ch]. Added also the function
7238 silc_socket_dup to increase the reference counter.
7240 This was mainly added because it is possible that the socket
7241 is removed underneath of pending command or other async
7242 operation. Now it won't be free'd and proper DISCONNECTING
7243 flags, etc. can be set to avoid sending data to connection that
7244 is not valid anymore.
7246 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
7247 the connection. After that it sets SILC_SET_DISCONNECTED.
7248 It is, however, possible that the socket data is not still freed.
7249 The silc_server_packet_process now checks that data is not
7250 read or written to connection that is DISCONNECTED. The socket
7251 get's freed when the reference counter hits zero.
7253 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7255 * Changed the client operation API: channel_message operation's
7256 `sender' is now the client entry of the sender, not the nickname
7257 and the `channel' is the channel entry, not the channel name.
7259 In the private_message operation the `sender' is now also the
7260 client entry of the sender not the nickname.
7262 Affected file is lib/silcclient/ops.h and all applications
7263 using the client operations.
7265 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7267 * Moved the calling of ops->connect() from connect_to_server_final
7268 into receive_new_id functin since that is the point when the
7269 client is actually allowed to send traffic to network. The
7270 affected file is lib/silcclient/client.c.
7272 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7274 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
7275 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
7276 (if needs broadcasting) instead of broadcasting the packets one
7277 by one which would make a burst in the network traffic.
7279 * Added `broadcast' argument to the functions in silcd/server.[ch]
7280 silc_server_create_new_channel[_with_id] to indicate whether
7281 to send New Channel packet to primary router.
7283 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7285 * Added new function into the silcd/server.[ch] files:
7286 silc_server_create_new_channel_with_id to create new channel with
7287 already existing Channel ID.
7289 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
7290 lib/silccore/silcpacket.h. This packet is used t send list of
7291 Set Mode payloads inside one packet. Server uses this to set
7292 the modes for the channels and clients on those channels, that it
7293 announced to the router when it connected to it. The protocol
7294 specification has been updated accordingly.
7296 * The silc_server_new_channel did not handle the packet coming
7297 from normal server as it normally does not send that. However,
7298 when it announces its channels it does send it. Implemented
7299 the support for that.
7301 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
7302 into the file lib/silccore/id.h.
7304 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7306 * Fixed memory leaks in the functions silc_idlist_del_client,
7307 silc_idlist_del_channel and silc_idlist_del_server in the file
7308 silcd/idlist.c. All of those leaked like a sieve.
7310 * Fixed some small memory leaks in the client's function
7311 silc_client_notify_by_server.
7313 * Added functions into silcd/server.c: silc_server_announce_clients,
7314 silc_server_announce_channels and silc_server_announce_server.
7315 These functions are used by normal and router server to announce
7316 to its primary router about clients, channels and servers (when
7317 router) that we own. This is done after we've connected to the
7320 These functions effectively implements the following packet types:
7321 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
7322 and SILC_PACKET_NEW_ID_LIST.
7324 * Added new functions into the silcd/packet_receive.[ch]:
7325 silc_server_new_id_list, silc_server_new_channel_list and
7326 silc_server_new_channel_user_list to handle the incoming
7327 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
7329 * Added support of changing Channel ID in the function
7330 silc_server_replace_id. If the server that announces a channel
7331 to the router already exists in the router (with same name but
7332 with different Channel ID), router is responsible to send
7333 Replace ID packet to the server and force the server to change
7334 the Channel ID to the one router has.
7336 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
7337 client that the Channel ID has been changed by the router. The
7338 normal server sends this to the client. Client must start using
7339 the new Channel ID as the channel's ID.
7341 Implemented handling of this new type into lib/silcclient/client.c
7342 into the function silc_client_notify_by_server.
7344 * Added new function silc_idlist_replace_channel_id into the files
7345 silcd/idlist.[ch] to replace the Channel ID.
7347 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7349 * Call silc_server_command_identify_check always when processing
7350 the IDENTIFY command in silcd/command.c
7352 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7354 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
7355 send keepalive packets. The packet can be sent by clients,
7356 servers and routers.
7358 Added function silc_socket_set_heartbeat into the file
7359 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
7360 If not set, the heartbeat is not performed. The actual
7361 heartbeat is implemented in the low level socket connection
7362 library. However, application is responsible of actually
7365 Added silc_server_send_heartbeat to send the actual heartbeat
7366 packet into silcd/packet_send.[ch]. Server now performs
7367 keepalive with all connections.
7369 * Added silc_task_get_first function into lib/silcutil/silctask.c
7370 to return the timeout task with shortest timeout. There was a bug
7371 in task unregistration that caused problems. TODO has been
7372 updated to include that task system must be rewritten.
7374 * The client library will now resolve the client information when
7375 receiving JOIN notify from server for client that we know but
7376 have incomplete information.
7378 * Rewrote parts of silc_server_remove_from_channels and
7379 silc_server_remove_from_one_channel as they did not remove the
7380 channel in some circumstances even though they should've.
7382 * Encryption problem encountered in server:
7384 The LEAVE command used to send the Channel Key packet to the
7385 router immediately after generating it. However, the code
7386 had earlier sent Remove Channel user packet but not immediately,
7387 ie. it was put to queue. The order of packets in the router
7388 was that Channel Key packet was first and Remove Channel User
7389 packet was second, even though they were encrypted in the
7390 reverse order. For this reason, MAC check failed. Now, this
7391 is fixed by not sending the Channel Key packet immediately but
7392 putting it to queue. However, this is more fundamental problem:
7393 packets that are in queue should actually not be encrypted
7394 because packets that are sent immediately gets encrypted
7395 actually with wrong IV (and thus MAC check fails). So, packets
7396 that are in queue should be encrypted when they are sent to
7397 the wire and not when they put to the queue.
7399 However, the problem is that the current system has not been
7400 designed to work that way. Instead, the packet is encrypted
7401 as soon as possible and left to the queue. The queue is then
7402 just purged into wire. There won't be any fixes for this
7403 any time soon. So, the current semantic for packet sending
7406 o If you send packet to remote host and do not force the send
7407 (the packet will be in queue) then all subsequent packets to the
7408 same remote host must also be put to the queue. Only after the
7409 queue has been purged is it safe again to force the packet
7412 o If you send all packets immediately then it safe to send
7413 any of subsequent packets through the queue, however, after
7414 the first packet is put to queue then any subsequent packets
7415 must also be put to the queue.
7417 Follow these rules and everything works fine.
7419 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7421 * Added new function silc_server_remove_clients_by_server to
7422 remove all client entries from ID list when the server connection
7423 is lost. In this case it is also important to invalidate all
7424 client entires as they hold the invalid server entry. This
7425 fixes fatal bug when server has lost connection and will reconnect
7428 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7430 * Made some sanity checks to silc_server_daemonise like to check
7431 whether the requested user and group actually exists.
7433 * Added sanity check to SKE's silc_ske_responder_finish to check
7434 that the public and private key actually is valid.
7436 * Invalidate the client's nickname when receiving Replace ID
7437 packet and the Client ID is being replaced. This means that the
7438 server will query the nickname if someone needs it (client)
7441 * Sort the ID Cache in client library when the ID Cache data
7442 has changed (needs sorting).
7444 * Do not allow for SILC client to create several connections to
7445 several servers. The client does not support windows right now
7446 and generating multiple connections causes weird behaviour.
7448 Irssi-silc client does support windows and can handle several
7449 connections without problems, see: www.irssi.org and SILC plugin.
7451 * Fixed some places where client was added to the IDList. The
7452 rule of thumb is following (in order to get everything right):
7453 If the client is directly connected local client then the
7454 `connection' argument must be set and `router' argument must be
7455 NULL to silc_idlist_add_client function. If the client is not
7456 directly connected client then the `router' argument must
7457 bet set and the `connection' argument must be NULL to the
7458 silc_idlist_add_client function.
7460 * The funtion silc_server_packet_send_local_channel actually did
7461 not check whether the client was locally connected or not. It
7462 does that now. Fixed a bug related to LEAVE command.
7464 * Fixed Remove Channel User payload parsing bug in server's
7465 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
7467 * The server's silc_server_save_channel_key now checks also the
7468 global ID list for the channel as it might not be in the local
7469 list. Fixed a bug related to LEAVE command.
7471 * Is this the end of the [<unknown>] buglet that has been lurking
7472 around for a long time? A little for loop fix in server's
7473 silc_server_command_whois_parse that is used by both IDENTIFY
7474 and WHOIS command. At least, this was a clear bug and a cause
7475 of one type of [<unknown>] buglet.
7477 * WHOIS and IDENTIFY commands call the function
7478 silc_server_command_[whois/identify]_check function even if
7479 we are not router server.
7481 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7483 * Added --with-gmp configuration option. If set the GMP
7484 is always compiled in the SILC source tree. If not set then
7485 it is checked whether the system has the GMP3 installed. If
7486 it has then the GMP won't be compiled (the system's headers
7487 and library is used), if it doesn't have it then the GMP is
7488 compiled in the SILC source tree.
7490 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7492 * Changed RSA private exponent generation to what PKCS #1
7493 suggests. We try to find the smallest possible d by doing
7494 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
7495 not security fix but optimization.
7497 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7499 * Added new config entry [Identity] to fork the server and run
7500 it as specific user and group. A patch from Bostik.
7502 * Imported Dotconf configuration library into lib/dotconf.
7503 This will be used to create the SILC configuration files later.
7504 It will appear in the distsribution after this commit.
7506 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7508 * A big code auditing weekend happening. Auditing code for
7509 obvious mistakes, bugs and errors. Also, removing any code
7512 Removed files for being obsolete:
7514 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
7515 inline in the file lib/silcutil/silcbuffer.h)
7517 o lib/silcutil/silcbufutil.c (the header has inline versions)
7519 Changed code to fix possible error conditions:
7521 o The buffer formatting routines now check that the destination
7522 buffer really has enough space to add the data. This applies for
7523 both buffer formatting and unformatting
7524 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
7525 unformatting was changed to accomodate following rules:
7526 XXX_*STRING_ALLOC will allocate space for the data into the pointer
7527 sent to the function while XXX_*STRING will not allocate or copy
7528 the data into the buffer. Instead it sets the pointer from the
7529 buffer into the pointer sent as argument (XXX_*STRING used to
7530 require that the pointer must be allocated already). This change
7531 makes this whole thing a bit more consistent and more optimized
7532 (note that the data returned in the unformatting with XXX_*STRING
7533 must not be freed now). The routines return now -1 on error.
7535 o Tried to find all code that use buffer_format and buffer_unformat
7536 and added return value checking to prevent formatting and
7537 especially unformatting errors and possible subsequent fatal
7540 o Changed ske->x and ske->KEY to mallocated pointers in
7541 lib/silcske/silcske.h. Fixed possible data and memory leak.
7543 o Added return value checking to all *_parse* functions. Fixed
7544 many memory leaks as well.
7546 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
7547 so that buffer overflows would not happen. All code now also
7548 checks the return value as it can fail.
7550 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7552 * Added reconnection support to server if the normal server looses
7553 its connection to the router (for example if router is rebooted).
7554 The server performs normal reconnection strategy implemented
7555 to the server. Affected file silcd/server.c.
7557 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7559 * Added new packet type SILC_PACKET_SET_MODE that is used to
7560 distribute the information about changed modes (for clients,
7561 channels and clients channel modes) to all routers in the
7562 network. Updated the protocol specification accordingly.
7564 Added functions into silcd/packet_send.c and
7565 silcd/packet_receive.c: silc_server_send_set_mode,
7566 silc_server_set_mode.
7568 Added new files silcmode.[ch] into lib/silccore that implements
7569 the encoding and decoding of Set Mode Payload. Added new type
7570 SilcSetModePayload. Moved the definitions of different modes
7571 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
7573 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7575 * Oops, a little mistake in server's connection authentication
7576 protocol. The protocol is not ended with FAILURE but with
7577 SUCCESS if the authentication is Ok. :) Affected file is
7580 * Implemented NICK_CHANGE notify handling in server in the file
7581 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
7582 the local clients on the channel. After the changing nickname
7583 in router environment snhould work and the [<unknown>] nickname
7584 should appear no more.
7586 The silc_server_replace_id function that receives the Replace ID
7587 payload now sends the NICK_CHANGE notify type also in the file
7588 silcd/packet_receive.c
7590 * Changed WHOIS and IDENTIFY command to support the maximum amount
7591 of arguments defined in protocol specs (3328 arguments). This
7592 fixed a bug that caused problems when there were more than three
7595 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7597 * Added extra parameter, command identifier, to the
7598 silc_client_send_command so that explicit command identifier
7601 Changed that ID list routines uses specific command identifier
7602 when sending WHOIS/IDENTIFY requests to the server so that they
7603 can be identified when the reply comes back.
7605 Affected files lib/silcclient/command.[ch],
7606 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
7608 * Added `sender' argument to silc_server_packet_send_to_channel
7609 to indicaet the sender who originally sent the packet to us
7610 that we are now re-sending. Ignored if NULL. Affected file
7611 silcd/packet_send.[ch].
7613 * Added some server statistics support in silcd/server_internal.h
7614 SilcServerStatistics structure and around the server code. Also
7615 send some nice statistics information when client is connecting
7618 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7620 * Fixed channel ID decoding in server's JOIN command reply in
7621 silcd/command_reply.c
7623 * Fixed braodcasting of replace ID payload to not to send it if
7624 we are standalone server in silcd/packet_receive.c.
7626 * Fixed all channel message sending routines to not to send
7627 packets to clients that has router set, since they are routed
7628 separately in the same function earlier. Affects file
7629 silcd/packet_send.c and all channel packet sending functions.
7631 * In USERS reply, res_argv[i] are not allocated, the table
7632 is allocated. Thus changed that free the table, not its
7635 * In server's whois_check and identify_check if the client is
7636 locally connected do not send any WHOIS commands - they are not
7639 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7641 * Fixed some minor bugs in client when sending WHOIS command. The
7642 arguments was in wrong order.
7644 * Removed statis function add_to_channel from server in
7645 silcd/command.c that was previously used with the joining but
7648 * Tested USERS command in router environment successfully with two
7649 routers, two servers and two clients.
7651 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7653 * Reorganized the USERS command and command reply in client library
7654 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
7655 When the command is given by user we register a pending command
7656 callback that will reprocess the command after the reply has been
7657 received from the server. When reprocessing the packet we then
7658 display the information. Thus, the USERS information is displayed
7659 now in the command callback instead of in the command reply
7660 callback. The processing of the command is same as previously
7661 when server has sent the command reply in the JOINing process.
7663 * Added to USERS command in silcd/command_reply.c to join the client,
7664 we didn't use to know about, to the channel after we've created
7665 a client entry for it. Also, for clienet we did know already still
7666 check whether it is on the channel or not and add it if not.
7668 * Removed silc_server_command_join_notify as the function and its
7671 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7673 * Changed the client's pending command handling to the same as the
7674 server's pending command handling. It is also now possible to
7675 execute command reply functions from other command reply
7676 function as the function callbacks for commands and command
7677 replies are one and same. The pending commands are not static
7678 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
7679 in client connection context. Thus, pending commands are server
7680 connection specific as it is convenient.
7682 Changed the function silc_client_command_pending and
7683 silc_client_command_pending_del and added new function
7684 silc_client_command_pending_check. Removed the
7685 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
7688 * Added cmd_ident, current command identifier, to the client
7689 connection context in lib/silcclient/client.h to keep track on
7690 command identifiers used in command sending. Client's command reply
7691 function handling now supports the mandatory command identifiers.
7693 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
7694 funtions in client to fully support pending command callbacks.
7696 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
7697 as one of the arguments to the application in the command reply
7700 * NOTE: The FORWARDED flag is depracated. It used to be depracated
7701 before first releasing SILC but came back. Now it is removed again
7702 and should come back nomore. The FORWARDED flag was used only
7703 by the JOINing procedure by forwarding the command packet to router.
7704 Now, the JOINing procedure has been changed to more generic (due
7705 to various router environment issues) and FORWARDED is not needed
7706 anymore for anything. The protocol specification is yet to be
7709 Now, removed silc_server_packet_forward from server and the flag
7710 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
7712 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7714 * Renamed NAMES command to USERS command. The NAMES was named that
7715 due to historical reasons. Now it is renamed. Also, rewrote
7716 parts of the USERS command. The nickname list is not sent anymore
7717 by the server. Only Client ID and mode lists are sent in the USERS
7718 command. Changed this also to the protocol specification.
7720 The client now resolves the names and stuff after it receives
7721 the USERS list from the server when joining to the channel.
7723 * WHOIS and IDENTIFY commands has been changed to support multiple
7724 Client ID's per command. One can now search for multiple users
7725 in the network by sending only one WHOIS or IDENTIFY command.
7726 Changed the code and the protocol specifications.
7728 * Removed silc_server_command_identify_parse and changed that IDENTIFY
7729 uses silc_server_command_whois_parse to parse the request. */
7731 * If normal server, do not parse the WHOIS and IDENTIFY requests
7732 before sending it to the router. Saves some time.
7734 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7736 * Fixed JOIN command on client library. Wrong number of arguments
7737 used to crash the client.
7739 * Added silc_server_channel_has_global function to check whether
7740 channel has global users or not.
7742 * Added silc_server_channel_has_local function to check whether channel
7743 has locally connected clients on the channel.
7745 * The silc_server_remove_from_one_channel now checks whether the
7746 channel has global users or not after given client was removed from
7747 the channel. It also checks whether the channel has local clients
7748 on the channel anymore. If it does not have then the channel entry
7749 is removed as it is not needed anymore.
7751 * The silc_server_notify now checks on JOIN notify whether the joining
7752 client is one of locally connected or global. If it is global then
7753 the channel has now global users on the channel and that is marked
7754 to the channel entry. Also, it now saves the global client to
7755 global list who is joining and JOINs it to the channel. This is
7756 for normal server, that is.
7758 Changed silc_server_send_notify_on_channel,
7759 silc_server_packet_relay_to_channel and
7760 silc_server_packet_send_to_channel check if we are normal server
7761 and client has router set (ie. global client) do not send the
7762 message to that client, as it is already routed to our router.
7764 * Implemented LEAVE notify type handling in silc_server_notify
7767 * Tested LEAVE command in router environment successfully. Tested
7768 with two routers, two servers and two clients.
7772 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
7774 * Implemented SIGNOFF notify type handling in silc_server_notify
7777 * silc_server_remove_id now removes the client entry from all channels
7778 it has joined and thusly sends SIGNOFF notify type.
7780 * Rewrote the NAMES list generation in server by removing two excess
7781 loops. The lists are created now inside one loop.
7783 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7785 * silc_server_remove_channel_user checks now also global list
7786 for channel and client.
7788 * silc_server_new_channel_user checks now both local and global
7789 list for channel and client. Fixed a bug in client id decoding.
7790 Used to decode wrong buffer.
7792 * silc_server_channel_message checks now both local and global
7793 list for channel entry.
7795 * Tested channel joining (hence JOIN) in router environment
7796 successfully. Tested with two routers, two servers and two
7799 * Tested channel message sending in router environment successfully.
7801 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7803 * Added silc_server_save_channel_key into server.[ch] to save the
7804 received channel key in Channel Key payload processing. It is
7805 also used in JOIN command reply handling.
7807 Equivalent function silc_client_save_channel_key added into
7808 client.[ch] into client library.
7810 * Changed JOIN command reply to send information whether the channel
7811 was created or not (is existing already) and the channel key
7812 payload. Changed protocol specs accordingly.
7814 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
7815 the request was sent by ID and not by nickname. Crashed on
7818 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7820 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
7821 now correctly save the received data.
7823 * silc_server_free_sock_user_data now notifies routers in the
7824 network about entities leaving the network.
7826 At the same time implemented functions silc_server_remove_id
7827 and silc_server_send_remove_id to receive and send REMOVE_ID
7828 packets. The packet is used to notify routers in the network
7829 about leaving entities. The ID removed will become invalid in
7832 * Added function silc_idlist_del_server into server. Removes and
7833 free's server entry from ID list.
7835 * silc_server_private_message function now checks, if we are router,
7836 that the destination ID really is valid ID, naturally.
7838 * In router when NEW_ID packet is received (for new client) the
7839 hash of the Client ID is saved in the ID Cache but the
7840 client->nickname is set to NULL, instead of putting the hash
7843 IDENTIFY command now also checks that client->nickname must be
7844 valid. If it is not if will request the data from the server who
7845 owns the client. Added new function
7846 silc_server_command_identify_check.
7848 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
7849 to set the command to already allocated Command Payload.
7851 * Tested private message sending in router environment with two
7852 routers, two servers and two clients. Fixed minor bugs and now
7855 * Fixed segfault from client's NAMES command. Used to crash if
7858 * Forwarded packets must not be routed even if it is not destined
7859 to the receiver. Changed server code comply with this.
7861 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7863 * Added `require_reverse_mapping' boolean value to ServerParams
7864 structure. If TRUE (not default) the server will require that
7865 the connecting host has fully qualified domain name.
7867 If the reverse mapping is not required and hostname could not be
7868 found the IP address is used as hostname.
7870 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7872 * Implemented version string checking to both client and server.
7873 The check is incomplete currently due to the abnormal version
7874 strings used in development version of SILC.
7876 * Changed all command functions in server to use the new
7879 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7881 * Changed char *data to unsigned char *data in ID Cache system to
7882 support binary data as ID Cache data. Changed code to support
7883 binary data in lib/silccore/idcache.c.
7885 * Renamed silc_server_packet_relay_command_reply to
7886 silc_server_command_reply as it is normal packet receiving
7887 function. Rewrote the function to accept command replys for
7888 servers and not only for clients.
7890 * Mark remote router always as registered server if we are connecting
7891 to it. Otherwise, commands sent by the router to us are ignored.
7893 * All ID List find routines now returns the ID Cache Entry pointer
7894 as well if requested.
7896 * WHOIS command works now in router environment, tested with two
7897 routers, two servers and two clients.
7899 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
7900 in router environment (as it is almost equivalent to WHOIS) but
7901 hasn't been tested thoroughly. Added new functions:
7903 silc_server_command_identify_parse
7904 silc_server_command_identify_send_reply
7905 silc_server_command_identify_from_client
7906 silc_server_command_identify_from_server
7908 * Disabled route cache adding because adding two different ID's with
7909 same IP replaces the old cache entry thus giving wrong route.
7910 The entry->router->connection is always the fastest route anyway
7911 so route cache may not be needed. Of course, new routes maybe
7912 established after receiving the ID when the entry->router->connection
7913 might not be anymore the most optimal.
7915 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7917 * Add route cache for received ID for fast routing.
7919 * Added silc_server_packet_route to route received packet on router
7920 that is not destined to us.
7922 * Renamed silc_server_get_route to silc_server_route_get.
7924 * Added id_string and id_string_len fields into SilcServer to
7925 include encoded ServerID for fast comparing without excess
7926 encoding of the ID's.
7928 * Cleaned up WHOIS command on server side. Added following static
7931 silc_server_command_whois_parse
7932 silc_server_command_whois_check
7933 silc_server_command_whois_send_reply
7934 silc_server_command_whois_from_client
7935 silc_server_command_whois_from_server
7937 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
7938 arguments in command replies. All command functions should be
7939 updated to use this macro.
7941 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7943 * Minor typo fixes on command reply handling on server.
7945 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7947 * Added silc_server_command_add_to_channel internal routine to add
7948 the client to the channel after router has created the channel and
7949 sent command reply to the server.
7951 * Added generic silc_server_send_command to send any command from
7954 * Use static buffer with ID rendering instead of duplicating data.
7956 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7958 * Fixed a channel user mode bug when joining to a channel server gave
7959 everybody channel founder rights, oops.
7961 * We mark ourselves as the router of the incoming server connection
7962 if we are router ourselves. This way we can check in some packet
7963 sending functions whether it is locally connected server. For
7964 incoming router connections we put NULL.
7966 * For router sending packets locally means now always sending the
7967 packet cell wide; to local clients and local servers. For normal
7968 server sending packet locally means sending it to only local
7971 * Fixed the JOIN command to really work in router environment. If the
7972 channel is created it is always created by the router. Router is
7973 also responsible of making the initial joining to the channel,
7974 sending JOIN notify to the sending server and distributing
7975 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
7976 does not exist server doesn't do anything else but forward the
7977 command to the router which performs everything.
7979 * Added silc_server_send_channel_key function to send the Channel Key
7982 * Added silc_server_create_channel_key to create new channel key. The
7983 channel key is now re-generated everytime someone joins or leaves
7984 a channel, as protocol dictates. Note: channel->key_len is the
7987 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7989 * Splitted server.[ch] finally. Created now packet_send.[ch] and
7990 packet_receive.[ch] to separate packet sending and receiving
7991 routines. The server.[ch] now includes everything else including
7992 actual packet processing (writing and reading data) and other
7995 Renamed silc_server_private_message_send_internal to
7996 silc_server_send_private_message. The routine is still though
7997 used only to relay private messages as server does not send
7998 private messages itself.
8000 Renamed silc_server_new_channel to silc_server_create_new_channel
8001 and added new function sicl_server_new_channel that handles the
8002 incoming New Channel packet. Added also new sending function
8003 silc_server_send_new_channel to send New Channel Payload.
8005 * Added new function silc_server_notify to process incoming notify
8006 packet to the server/router. Server may then relay the notify
8007 to clients if needed.
8009 * Added new function silc_server_new_channel_user to process incoming
8010 New Channel User packet. Router will redistribute the packet and
8011 send JOIN notify to its local clients and locally connected servers
8012 if needed. Normal server will send JOIN notify to its local client
8013 on same channel when received this packet. Added also corresponding
8014 sending function silc_server_send_new_channel_user to sent the
8017 * Added boolean route argument to send_notif_to_channel and
8018 packet_send_to_channel functions to attempt to route the packet
8019 if it is TRUE and send only locally if it is FALSE.
8021 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8023 * silc_server_replace_id now broadcasts the received replace ID
8024 packet if it is not broadcast packet already. The router must
8025 broadcast to inform other routers about changed ID.
8027 * Added backpointer to server's router into SilcServer context in
8028 silcd/server_internal.h.
8030 * Fixed silc_server_packet_broadcast to send correct broadcast
8033 * The channel key is now distributed to the local client as soon
8034 as it is received from the router (in router environment) so that
8035 no other packet may be sent for the channel until client has
8038 * silc_server_remove_channel_user now broadcasts the received
8039 Remove Channel User packet if it is not broadcast packet already.
8040 The router must broadcast to inform other routers about removed
8043 * Added users field into SilcPacketContext that is a reference count
8044 of the context. One can increase the reference count by calling
8045 silc_packet_context_dup which is now changed to just increase the
8046 reference count instead of duplicating the data. The reference
8047 count is decresed by calling silc_packet_context_free that will
8048 free the data after the reference count hits zero.
8050 For now on the packet context and everything allocated into it
8051 (including the raw packet from network) must be freed by calling
8052 the new silc_packet_context_free function. Added also new function
8053 silc_packet_context_alloc that must be used now to allocate the
8054 context. This also means that if a routine is asynchronous from
8055 silc_[client/server]_packet_parse_type the packet context must
8056 be duplicated by calling silc_packet_context_dup. Otherwise it
8057 gets free'd after silc_[client/server]_packet_parse_type returns.
8058 Also, one must remember that if packet is duplicated then its
8059 reference count must be decresed by calling the free function as
8060 many times as it was duplicated.
8062 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
8063 from both client and server.
8065 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8067 * Made joining to a channel working in router environment.
8069 * Cleaned up JOIN command on server side and create function
8070 silc_server_command_join_channel internal routine to make the
8073 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8075 * Changed silc_command_pending list to SilcDList. Also, added
8076 `ident' field to SilcServerCommandPending structure to identify
8077 the reply and to call correct callback.
8079 Added silc_server_command_pending_check function to replace the
8080 corresnponding macro. The silc_command_pending list is not
8083 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
8084 to set identifier to previously allocated Command Payload. It
8085 is used to set identifier for command when resending Command
8088 * Added silc_command_payload_encode_payload to encode Command
8089 Payload buffer from SilcCommandPayload structure.
8091 * Added silc_argument_payload_encode_payload to encode Argument
8092 payload buffer from SilcArgumentPayload structure.
8094 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8096 * Changed WHOIS command to support router connection on server side.
8097 The whois request is always sent to router unless the server is
8098 standalone server. After server has received the reply from the
8099 router will it send the reply to the client.
8101 * Added silc_server_packet_broadcast into silcd/server.[ch] to
8102 broadcast received broadcast packet. The function is used only
8103 by router. The broadcast packet is always sent to the router's
8106 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
8107 render given ID to printable string, for log files for example.
8109 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8111 * Made basic router to router connections working. At least they
8112 can now connect to each other but nothing really works the way
8113 they are supposed - yet.
8115 * Added new initiator token to RouterConnection configuration
8116 file in silcd/serverconfig.[ch]. It is used to tell whether we
8117 are the initiator to the remote router or whether we'll expect
8118 the other end to connect.
8120 * Moved registering of listener task to silc_server_init, hence
8121 the server starts listenning as soon as it is run, even if it
8122 does not have connections to other routers. Let's see how well
8125 * Changed default connection retry timeouts for more suitable in
8128 * Removed cipher and such arguments from silc_idlist_add_client
8129 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
8130 Added new function silc_idlist_add_data to add the keys and stuff
8133 * Added SilcIDListData structure and added it to SilcClientEntry
8134 and SilcServerEntry as their first field in the structure. This
8135 way we can explicitly cast the ID entries to the SilcIDListData
8136 structure and get common data for the entries. In past, we had
8137 to first check what type of connection it is and then cast it to
8138 correct ID entry type. Now, we can directly cast the opaque
8139 pointer to the SilcIDListData (no matter what ID entry it actually
8140 is) and get the data needed.
8142 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8144 * Wow, found a bug in scheduler. The scheduler uninitialized itself
8145 in some circumstances even if threre were timeout tasks, though not
8146 IO tasks, but tasks anyway. Now fixed.
8148 * Defined SilcServerConnection structure to hold connection specific
8149 stuff about directly connected servers and routers. The definition
8150 is currently in silcd/server_internal.h. I thought about having
8151 a bit more important role fro this struct but for now it is used
8152 only when connecting to other server (or router actually).
8154 * Added connecting retry support in server when connecting to
8155 router(s). The retry feature implement exponential backoff
8156 algorithm. Also, added SilcServerParams structure to hold default
8157 parameters for server. For now, it include these retry settings
8158 and are hard coded. After server is moded to be as Silc Server
8159 Library this structure will be more important.
8161 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8163 * Changed client librarys channel->clients table to SilcList and
8164 changed code accordingly.
8166 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8168 * Changed client's channel table to SilcList and changed code
8169 accordingly. Also changed SilcChannelClientEntry to include back-
8170 pointer to the channel so that client entry can use that structure
8171 as list as well and we have fast cross-reference to the channel.
8172 This change dramatically decreased the complexity of channel
8173 handling with client entry and vice versa (removed one extra
8174 loop when searching for channel entry from many functions).
8176 * Changed server->sim from table to SilcDList and changed code
8179 * NAMES command can now be used from user interface. It will show
8180 the user list on the channel, neatly.
8182 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
8183 Code now saves realname of the user if it becomes available.
8185 * Renamed configure.in to configure.in.pre and made ./prepare
8186 script to automatically add correct version string to
8187 configure.in which it creates from configure.in.pre.
8189 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8191 * NAMES command reply now shows users mode with the nickname when
8194 * Moved silc_client_ch[u]mode[_char] functions from
8195 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
8196 place sucks, they are utility functions and should be in some
8199 * Fixed some unsigned int's to unsigned short's. Patch by cras.
8201 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
8204 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8208 * Added TRQ (efficient deque and list library) into lib/trq. This is
8209 a very good list library that is currently used in the SILC. Defined
8210 SilcList API over the library because I didn't like the API very
8211 much. See lib/trq/silclist.h for the API and examples of how to
8212 use the API. Fixed various places in the code to use the new
8213 SilcList API. The SilcList is meant for lists that has a structure
8214 already defined as a list. It is not suitable to add just some
8215 context to the list (in TRQ, the context is the list actually).
8217 So, I defined SilcDList that can be used for the purpose where
8218 predefined list structure does not exit. This can be used as
8219 such list. Now some context just can be added to the SilcDList.
8220 Currently this list is not used in the SILC just yet, though there
8221 are a lot places where this can replace dynamically allocated
8222 tables and I will fix these places, later, to use SilcDList.
8223 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
8224 and use TRQ internally).
8226 Also fixed some annoying warning messages that the original TRQ
8227 code generated. Also minor changes to TRQ's Makefile.in.
8229 * Added support for querying by Client ID to both WHOIS and
8230 IDENTIFY commands into server, as required by the protocol.
8232 * Removed method function pointers from SilcBuffer structure. They
8233 weren't used to anything and just increased the context size for
8234 no good reason. This change also made silc_buffer_alloc and
8235 silc_buffer_free functions inline functions.
8237 * Disabled command flooding detection support until it's fixed so
8238 that it accepts commands in but does not execute them more than once
8241 * Added silc_net_localhost(), to return local hostname, into
8242 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
8243 that must be initialized before calling silc_client_init.
8245 * Added new function: silc_server_send_notify_on_channels to send
8246 notify messages to all channels client has joined. It is assured
8247 that the message is sent only once per client.
8249 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
8250 lib/silcutil/silcutil.[ch] as silc_format function. The new
8251 function is generic and is used by server as well, not only by
8252 the logging routines.
8254 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
8255 the provided version string was not acceptable. Added new function:
8256 silc_ske_check_version into lib/silcske/silcske.h. The function
8257 must be implemented by the application (client or server) and it
8258 does not reside in the SKE library. The function checks the version
8259 string remote end sent.
8261 * Added back pointers (to opaque context and to SilcSocketConnection)
8262 into SilcPacketContext structure into lib/silccore/silcpacket.h.
8264 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
8265 duplicate packet context structure.
8267 * Changed `notify' client operation to send same arguments as client
8268 receives from server except for ID's. ID's are mapped to correct
8269 ID entry and that is returned. Also, if channel entry is not sent
8270 by server but the notify is for channel the channel entry is sent
8271 to application (otherwise application doesn't know that it is for
8272 channel (library gets it from packet's Destination ID)).
8274 * Added silc_client_remove_from_channels into client library to
8275 remove a client from all channels it has joined to. Used when
8276 received SIGNOFF notify from server. Added also new function
8277 silc_client_replace_from_channels to replace old ID entry with
8278 new ID entry on all channels. Used when received NICK_CHANGE
8281 * Fixed ID Cache list handling in silc_idlist_get_client in
8282 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
8283 to get (or query) client by ID.
8285 * Updated TODO list.
8287 * Added connection authentication status message defined by the
8288 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
8289 support for these into the code in client and server side.
8291 * Added generic function silc_client_send_command to send any command
8292 with variable argument list. Application should use this function
8293 to send commands if the command functions provided by the library
8294 does not suite for the application's user interface needs.
8296 * Added new `failure' client operation. Application is notified about
8297 received failure packet if client is executing a protocol. In this
8298 case the protocol's execution has failed.
8300 * Added SKE's end notify to send the SKE_SUCCESS notify message that
8301 is required by the protocol.
8303 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
8304 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
8307 * Added status flag to SilcSKE object to indicate realtime status
8308 of the SKE protocol.
8310 * Application receives now exactly same command reply arguments as
8311 the library receives from server. However, if ID is received the
8312 corresponding ID entry is returned to the application (eg. Client
8313 ID is mapped to correct SilcClientEntry entry and that is returned).
8314 Changed command_reply client operation due to this change.
8316 * Changed all ID's in commands and in command replys as ID Payloads.
8317 Change affected both client and server side codes.
8319 All ID's sent in SILC network (with execption of ID's in SILC
8320 Packet header) are sent in ID Payload to support variable length
8323 * Server now notifies nick changes and notifies all clients on
8324 the channels about the new nickname (about the new Client ID,
8327 * Implemented CMODE command to change channel modes. Supports all
8328 channel modes defined by the protocol specs except ban and invite
8329 lists. (Also, private channel key mode is supported but support for
8330 setting private channel key in client is missing, thus, this mode
8331 has no effect on client side (except that server requires that the
8332 client uses private channel key and normal channel traffic does not
8335 Also, invite mode works per se, but INVITE command does not work
8336 yet correctly, so you can set channel as invite only channel but
8337 inviting clients to the channel does not work (it is yet to be
8338 thought what's the best way to do it).
8340 * Added new command SILC_COMMAND_CUMODE to change user mode on the
8341 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
8342 Implemented CUMODE command to change user's mode on the channel.
8343 Supports all modes defined by the protocol specs.
8345 * Added NAMES command reply to return users modes on the channel.
8347 * Removed unnecessary and slow ciphers from lib/silccrypt.
8349 * Set SO_KEEPALIVE option to connection sockets by default.
8351 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
8353 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
8354 redefined the Notify Payload into protocol specs.
8356 * Added silc_id_payload_parse_id to get ID directly from raw
8359 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8361 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
8362 accept searching by Client ID as well.
8364 * Added support for LEAVE and SIGNOFF notify types in client library.
8366 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
8367 to parse ID Payload from raw data.
8369 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8371 * Added flags parameter into silc_ske_assemble_security_properties
8372 function in lib/silcske/silcske.[ch].
8374 * Changed notify client operation to fit better for notify messages
8375 sent by server. The notify payload received from server is now
8376 passed to the application (after parsing it to SilcNotifyPayload).
8377 It is application's responsibility to retrieve the arguments
8378 from the payload and show the message the way it wants. The message
8379 sent by server is implementation specific.
8381 * Changed public keys to comply with the protocol specification.
8382 Old public keys are not supported anymore and are not compatible.
8384 * Removed nickname from Channel Payload as the latest draft removed
8385 it. The client must resolve the nickname from the NAMES command
8386 reply received when it joined the channel.
8388 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
8390 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8392 * Fixed some errors in protocol specification drafts.
8394 * Created lib/silccore/silcnotify.c to implement Notify Payload
8395 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
8396 generic payloads described by protocol specifications. The file
8397 includes implementations for ID Payload and Argument Payload.
8399 * Changed Command Payload implementation to use the new Argument
8400 Payload. Changed command_xxxx_payload to command_payload_xxxx
8401 to comply with SILC coding conventions.
8403 * Added suppport for Argument Payload handling in Notify Payload
8404 implementation as protocol requires it. Added the new support
8405 into server and client lib as well.
8407 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8409 * Added support for multiple nicknames on same channel. [n] is
8410 added locally to the nickname if there are more than one same
8411 nicknames on the channel.
8413 * Server now sends all nicknames that matched WHOIS request.
8414 Client also shows the list received from server.
8416 * Added TOPIC command to client side. User can now set and show
8417 current topic on channel.
8419 * Added MOTD command to client and server. Also, server sends the
8420 motd when client connects to the server.
8422 * Changed version strings to comply ISO 8601.
8424 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8426 * Fixed protocol error handling in client library. It should now
8427 cope even if the SKE fails for some reason.
8429 * Made new protocol specification drafts for submitting to IETF.
8431 * Implemented TOPIC command to server in silcd/command.c.
8433 * Added two new notify types into lib/silccore/silcnotify.h:
8434 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
8435 notify nickname change and topic setting/change on a channel.
8437 * API change of command_reply operation in client library. The
8438 application gets now the status type received from server as well.
8440 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8442 * Removed the function just added to lib/silcutil/silcschedule.[ch].
8444 * Cras fixed and optimized the packet handling even further and
8445 it should work now. Minor change to the prototype of function
8446 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
8448 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8450 * Added new function into lib/silcutil/silcschedule.[ch]:
8451 silc_schedule_with_fd to select() a specified fd. The function
8452 returns after timeout expires or data arrives or goes. The
8453 function is used by packet routines to wait that all data is
8454 received from network.
8456 * Fixed data reading from network in lib/silccore/silcpacket.c.
8457 The code now assures that all data is read from the fd and then
8458 continues packet processing. This was a bug fix since the code
8459 used to drop some data in some circumstances.
8461 * Added new function into lib/silcclient/client.[ch]:
8462 silc_client_start_key_exchange to start key exchange after
8463 connection has been established to server. The code internally
8464 now uses this funtion but its main purpose was to provide it
8465 for applications that perform their own connecting. After
8466 application has created a connection it merely calls this
8467 function to start the key exchange between client and server.
8468 The library takes care of everything else after that.
8470 Updated also lib/silcclient/README to explain the usage of
8473 * Do not send to application information that connection has
8474 been established. Application gets notified it by connect
8477 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8479 * Applied cras's patch to add silc_schedule_one function. The
8480 function runs scheduler once and returns.
8482 * Fixed the scheduler after cras messed it up. The timeout
8483 handling works now as it's supposed to work.
8485 * Added into lib/silccore/ silcnotify.h to include notify
8486 message types support. Changed silc_server_send_notify*
8487 functions, in server.[ch], to support those new notify types.
8488 Added the support for the notify types into client library,
8489 as well. Added new notify client operation into ops.h in
8492 * Changed silc_server_packet_send_to_channel to send normal
8493 packets instead of just channel message packets. The function
8494 is now used to send the notify packets to channels. It is not
8495 used to send channel message packets anymore, as server never
8498 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
8499 va_arg()s as it seems to require it nowadays. I guess, if SILC
8500 is compiled with older va_arg() the new code should work anyway.
8502 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8504 * Splitted core library. Core library (lib/silccore) includes
8505 now only SILC protocol specific core (and common) components.
8506 Created new utility library (lib/silcutil) that includes more
8507 generic purpose stuff. The stuff for util library was taken
8508 from the old core library. This was minor and easy split.
8510 * Created SILC Client Library (lib/silcclient) that includes
8511 implementation of the SILC client without user interface. This
8512 was major move from silc/ directory. The code has been changed
8513 so that it is transparent towards the user interface. The
8514 silc/ directory includes now the same user interface as before
8515 and it uses the new client library. Read lib/silcclient/README.
8516 Basicly, the client library performs everything else related
8517 to SILC except user interface handling. Also, configuration
8518 files are considered to be part of user interface and library
8519 does not handle them.
8521 This change also changed a lot of structures, function naming etc.
8522 Most important change was that SilcClientWindow object was
8523 renamed to SilcClientConnection in the client library. Created
8524 also new file lib/silcclient/ops.h. Also added new files
8525 silc/local_command.[ch] and silc/client_ops.[ch].
8527 All these changes were made to make it easier for user interface
8528 designers to create what ever user interface for the SILC client
8531 It is also expected that the server will be moved to lib
8532 directory as well and SILC Server Library will be created;
8533 sometimes in the future.
8535 * Removed Local commands from lib/silccore/silccommand.h as
8536 they are application specific and new client library does not
8537 handle any of those anymore.
8539 * Several functions moved to lib/silcutil/silcutilc.[ch] from
8540 old client implementation in silc/.
8542 * Added support for callback functions in SILC_LOG_* macros.
8543 Application can now set its own callbacks that will be called
8544 instead of using the default functions that will always print
8545 the debug messages to stderr (or stdout). Also, debugging can
8546 now be disabled by setting silc_debug to FALSE and re-enabled by
8547 setting it to TRUE. Note, that logging will still work even
8548 if debugging is disabled.
8550 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
8551 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
8552 silc_log_reset_debug_callbacks.
8554 * To enable debugging in silc client one must give now -d
8555 option on command line.
8557 * Changed silc_schedule_init to automatically allocate task queues
8558 if they are not allocated before calling it.
8560 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8562 * Added GMP 3.1 into math library.
8564 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8566 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
8567 a channel in SILC network. The packet is used by servers and
8568 routers to notify other routers that user has left a channel.
8569 This little feature was missing until now. Added the feature
8570 to protocol specification as well.
8572 Added functions: silc_server_send_remove_channel_user and
8573 silc_server_remove_channel_user into server.[ch].
8575 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
8576 lib/silccore/silcpacket.h. However, they are not implemented
8579 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8581 * Fixed joining to a channel and sending channel messages
8582 between server and router. The channel message sending should
8583 now work inside a cell.
8585 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8587 * Fixed the private message sending between server and router.
8588 The private message sending should now work inside a cell.
8590 * Added silc_server_replace_id into server.[ch] to replace
8591 existing ID in the SILC network.
8593 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
8594 and silc_idlist_replace_server_id into idlist.[ch] in server.
8596 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8598 * Fixed the server to server connections. Server can again now
8599 connect to router. Router to router connections probably does
8602 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8604 * Added dynamic protocol registering support. Now protocols can
8605 registered and unregistered on the fly. Patch by cras.
8607 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8609 * Added lib/contrib directory to hold routines that some platforms
8610 don't have but are needed by SILC.
8612 * Added getopt.c, getopt1.c and getopt.h from GNU C library
8613 into lin/contrib to provide getopt() and getopt_long() for
8614 those who don't have it.
8616 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8618 * Added AWAY command to client. When away message is set and
8619 client receives a private message packet the client automatically
8620 replies to the sender with the away message.
8622 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
8623 bug seemed to be the cause of recent problems when compiling
8626 * Added version detection support to SKE protocol specification
8627 and added the new changes to the SKE implementation as well.
8628 There were other minor changes in the SKE protocol as well.
8630 Many changes in lib/silcske/silcske.[ch] and in
8631 lib/silcske/payload.[ch].
8633 * Added ^U functionality, clear input line. Patch from cras.
8635 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8637 * Mainly small bugfixes on core library. Fixed some debugging
8638 logging and buffer overflow in silclog.c.
8640 * Updated config.sub and config.guess on the distribution tree.
8642 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8644 * Added command lagging support in server. Client may execute
8645 commands now only once in two seconds.
8647 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8649 * Optimized packet reception. MAC computation and checking is now
8650 also more optimized. A lot previously duplicated code is now
8651 used as generic by both client and server.
8653 * Fixed key pair generation in clientutil.c
8655 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8657 * Added into lib/silccore/silcbufutil.[ch] new function;
8658 silc_buffer_realloc.
8660 * Moved generic packet sending/encryption functions to
8661 lib/silccore/silcpacket.[ch] from client and server. Some
8662 rewriting of the functions.
8664 * Moved all generic packet reception/decryption functions to
8665 lib/silccore/silcpacket.[ch] from client and server. The
8666 packet processing is now much cleaner in both client and server.
8667 These were major changes in both client and server.
8669 * Created many common functions in server to do packet sending.
8670 Previously code were duplicated a lot, this has been removed
8673 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8675 * Rewrote major parts of the ID cache system. Don't know
8676 whether it is better now or not but at least the API is more
8679 * Major rewrite on ID cache stuff on client because of the ID
8680 cache API changes. Added idlist.c to client.
8682 * Also major rewrite on ID cache stuff on server as well.
8683 Major rewrite of idlist.[ch]. SilcXXXList's are now named
8684 SilcXXXEntry's. We won't keep anymore idlist specific pointers
8685 in hand, instead they are all put into the ID cache system now.
8686 All server_idlist_* routines uses ID cache now instead of
8687 traversing its own lists (those lists does not exist anymore).
8688 SilcIDList though still exists. Also, SilcXXXEntry's are
8691 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8693 * Finally made the SKE implementation compliant to the protocol
8694 specification. All mp integers are now binary encoded as
8695 opposed being HEX encoded.
8697 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
8700 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
8701 functions: silc_[encode/decode]_pem. Also added function
8702 silc_encode_pem_file to PEM encode with newlines ('\n') for
8705 * SILC public keys are now encoded either PEM or binary. Same
8706 option is for private keys as well. By default private keys
8707 are binary encoded and public keys PEM encoded. Silly HEX
8708 encoding were removed.
8710 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
8711 function to create fingerprints.
8713 * Fixed a bug in SHA1; does not change the original data anymore.
8715 * Partly implemented INFO command on client and server side.
8716 Fixed CLEAR command. Changes to SERVER command; show current
8717 server(s) when giving command without arguments. Added
8718 VERSION command to client.
8720 * Added check to server that unregistered connections cannot
8721 execute commands (unless it is specificly allowed).
8723 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8725 * Fixed screen refresh.
8727 * Fixed channel joining bug from client. On some circumstances
8728 client tried to join to a channel it had already joined.
8730 * Added public key verification process into client's protocol.c.
8731 The client now verifies the public key from user and saves
8732 it into ~./silc/serverkeys/ directory.
8734 Added into: clientutil.[ch]: silc_client_verify_server_key.
8736 * Changed SKE protocol's silc_ske_initiator_finish function
8737 to accept callback function that verifies the received public
8738 key. Removed old silc_ske_verify_public_key function.
8740 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8742 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
8743 silc_pkcs_private_key[_data]_set.
8745 * Made the password and public authentication more cleaner in
8746 server's protocol.c.
8748 * Removed historic and obsolete protocol `channel_auth' from
8749 both client and server.
8751 * Removed wrong way of sending command status messages from
8752 server to client in server's command.c. The old way violated
8753 protocol specification.
8755 Changes to silccore/silccommand.[ch]: removed
8756 silc_command_encode_status_payload -> not needed anymore,
8757 changed silc_command_encode_payload_va to accept extra
8758 argument on variable argument list. The argument type must
8759 now be provided to the function. Also, added new function:
8760 silc_command_encode_reply_payload_va which is same as
8761 normal command_encode_payload_va except command status type
8762 is provided as extra argument.
8764 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8766 * Added ~./silc directory handling. The directory includes the
8767 public and private keys for the client.
8769 Added silc_client_check_silc_dir, silc_client_create_identifier
8770 and silc_client_load_keys.
8772 * Implemented SILC protocol compliant public key. Added public
8773 and private key saving to and loading from files.
8775 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
8776 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
8777 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
8778 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
8779 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
8781 Implemented: silc_pkcs_save_[public/private]_key[_data] and
8782 silc_pkcs_load_[public/private]_key.
8784 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8786 * Added silc_server_get_route (route.[ch]) to get connection
8787 data for the fastest route for given ID.
8789 * Implemented INVITE command on client and server. The command
8790 were re-defined in the SILC Protocol Specification and the
8791 implementation now complies with the specification.
8793 * Implemented PING command on client and server.
8795 * Implemented NAMES command on client and server. The server side
8796 supports currently only normal server not router server yet.
8797 Some changes to NAMES definition in SILC protocol specification.
8799 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8801 * Implemented LEAVE command on client and server.
8803 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
8804 again. This change was made to the protocol as well. Server
8805 should not violate the protocol specification anymore.
8807 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8809 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
8810 was tested. SOCKS4 was not but should work anyway.
