5 to operators. Added macro SILC_SERVER_SEND_OPERS macro
6 to send variable argument notify to operators.
7 Affected files silcd/packet_send.[ch] and silcd/server.h.
9 * Removed UMODE rights checking with UMODE_CHANGE notify.
10 Affected file silcd/packet_receive.c.
12 * Server/router operator now receives notify when network
13 switches to backup router and when it resumes the use of
14 primary router. Affected file silcd/server.c and
15 silcd/server_backup.c.
17 * Fixed the updating of client information after backup
18 resuming protocol is over; update all except local clients
19 to the new primary router. The affected file is
22 * Added support for closing active connections in rehash
23 that were unconfigured by the user. Supports currently
24 closing server and router connections. Affected file
27 * Rewrote some SILC_LOG_DEBUG's in silcd/server_backup.c.
29 Sun Jun 23 17:32:31 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
31 * Don't do SILC_STRING_LANGUAGE encoding if the outbuffer
32 is NULL since seems that on some platforms NULL is allowed
33 and on some it's not. Fallback encoding is used instead.
34 Affected file lib/silcutil/silcstrutil.c.
36 * Fixed statistics updating for incoming server connection
37 which could cause problems when re-connecting. Affected
40 * Preliminary backup router support for standalone router
41 added. Affected files in silcd/.

44 and after backup protocol. Affected file is
45 silcd/server_backup.c.
47 * Added support for reconnecting to remote server connection
48 even if the protocol fails, and if the configuration wants
49 us to keep trying to connect anyway.

58 * Added silc_client_udpate_server function to update changed
59 server info. Affected file lib/silcclient/idlist.[ch].
61 * Added check for server entries that are being resolved when
62 notify is received. If being resolved, handle the received
63 notify only after it's resolved so that all notifys are
64 handled in same order as received from the server.
66 Added similar resolver check to channel entries. Every
67 notify that cause resolving of any information that affects
68 channel entry marks the channel entry in waiting state.
69 After whatever resolving is over the waiters are signalled
70 and only then the notifys are handled in the same order
71 as delivered from the server.
73 Affected files are lib/silcclient/idlist.[ch], and
76 * Fixed KILLED notify handling in normal server. Affected
77 file silcd/packet_receive.c.
79 * Added SILC_IDLIST_STATUS_LOCAL which indicates that entry
80 is locally connected, or was locally connected (but may
81 be detached and connection is not active). Added also

105 Affected files configure.in.pre, lib/contrib/Makefile.am.
107 Sat Jun 22 12:49:21 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
109 * All CMODE_CHANGE and CUMODE_CHANGE notifys are now sent back
110 to the sender of the notify too, to avoid situation where two
111 notifys are in the network at the same time going to oppsite
112 directions. Affected file silcd/packet_receice.c.
114 Fri Jun 21 10:00:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
116 * Delete the client from channel even if the cilent->id is

118 removing from channels (theoretically at least). Affected
119 file silcd/server.c and silcd/server_util.c.
121 * Free the client data too when resuming is not successful.
122 Affected file silcd/packet_receive.c.

127 * Added SILC_PRIMARY_ROUTE and SILC_BROADXAST macros to
128 silcd/server_internal.h. SILC_PRIMARY_ROUTE Returns pointer
129 to the primary router connection, the other one returns
130 TRUE if packet must be broadcasted to network.
132 * All notifys that are destined to primary router (to network)
133 are now automatically sent to backup routers even if the
134 router is standalone (and has backup router). Affected files
137 * Added --without-irssi and --without-silcd configuration
138 options for disabling the compilation of these applications.
139 Affected file configure.in.pre and prepare.

165 command reply from router, on normal server. Otherwise
166 joinig +a channels from normal server is not possible.
167 Affected file silcd/command.c.
169 * Fixed a bug in TOPIC_SET notify handling. The notifier
170 may be other than client too, like server or channel.
171 It expected it to always be only client and ignored the
172 notify. Affected file silcd/packet_recieve.c.
174 * Removed some (unnecessary) debug printing from
175 lib/silccore/silcid.c and lib/silccore/silcargument.c.
177 * Do not force CMODE_CHANGE when server is announcing new
180 Router announces stuff only after server reannounces channel
181 after CHANNEL_CHANGE notify.
183 These fixes optimizes the announcing procedure, and perhaps
184 fixes some problems too. Affected file silcd/packet_receive.c.
186 * Fixed SERVER_SIGNOFF sending to local clients. It was
187 totally broken and sent the notify to all local clients,
188 instead of only to those that was on same channel as the
189 signing off clients. Affected file silcd/server_util.c.
191 * Added -D option to server. It can be used to give debug
192 level. The levels are from 0 - 99, and are predefined for
193 smooth server debugging. (see silcd.c for the predefined
194 levels). Affected file silcd/server.c.
196 Wed Jun 19 16:01:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

206 channel. Affected file silcd/command.c.
208 * Better checking for founder mode setting when CUMODE_CHANGE
209 notify is received. Affected file silcd/packet_receive.c.

667 Mon Apr 15 19:57:57 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
669 * Added new notify type SILC_NOTIFY_TYPE_ERROR and specified
670 that it is used to send error notifys if error occurs during
671 some SILC packet processing, except commands. The error
672 types are same as for command reply types. Defined that
673 if private message is sent to unknown Client ID the error
674 is sent in SILC_NOTIFY_TYPE_ERROR instead of command reply.
675 Updated the protocol specs and code. Affected files are
676 lib/silccore/silcnotify.h, added lib/silccore/silcstatus.h,
677 lib/silcclient/client_notify.c, silcd/packet_receive.c,

682 The <Requested Attributes> (defined in a separate document)
683 can be used to request additional information about user
684 not returned by standard WHOIS command. Defined that server
685 can send WHOIS command directly to client. Client provides
686 the requested attributes to the server. Updated the protocol
687 specs. Protocol TODO #4. Implementation is not done yet

715 * Added resolve_cmd_ident field to the SilcClientEntry structure
716 too so that if the entry is for example being resolved so
717 another command may attach to the same pending command reply
718 without requiring to resolve the same entry again. Added
719 support for adding multiple pending commands for one
720 command idenfier. Affected files lib/silcclient/command.[ch],
721 lib/silcclient/command_reply.[ch], lib/silcclient/idlist.h.

738 so that WHOIS always shows joined channels also in normal
739 server and not just on router. Affected file is
740 silcd/command_reply.c.
742 Thu Apr 11 22:29:33 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

768 mask to the client. Updated protocol specs and the server.
769 Affected file is silcd/command.c.
771 * Changed the Killer's Client ID in KILLED notify to be just
772 any ID payload since router server is allowed to kill as well.

798 Mon Apr 8 23:57:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
800 * Redefined the Status Payload to include now two 8 bit fields,
801 instead of one 16 bit field. This now makes it possible to
802 send list of errors. Updated the protocol specs and the code
803 in core library, client library and server. Protocol TODO #1.
804 Affected files are lib/silccore/silccommand.[ch],
805 lib/silcclient/command_reply.[ch], silcd/command.c,

808 Mon Apr 8 19:57:40 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
810 * Added config parse status SILC_CONFIG_EPRINTLINE, this status
811 must be handled by the application and should tell the application
812 that an error message was already printed, and it should print the
813 config coords (line, filename, ...). Affected files are
814 silcd/serverconfig.c, lib/silcutil/silcconfig.[ch].

835 Sun Apr 7 17:07:59 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
837 * Added STATS command to the protocol after all, to return
838 various statistical information about the network. It can
839 be used by clients to retrieve statistical information, and
840 servers may use it to to fetch cell and network wide
841 statistics from router. Updated the protocol specs and
842 implemented it to the server. Protocol TODO #16.
843 Affected files are lib/silccore/silccommand, silcd/command.[ch],
844 silcd/command_reply.[ch].
846 Sat Apr 6 17:08:58 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
848 * The LIST command reply in client libary now adds new channel
849 entry if the returned channel doesn't exist yet in cache,
850 and returns the channel entry to the application in the
851 command_reply client operation. Affected file is
852 lib/silcclient/command_reply.c.
854 * Changed the channel message payload's MAC generation to
855 include the IV in the MAC as well. This way all relevant
856 parts of the channel message payload are authenticated also
857 with the channel message MAC (and not only by packet MAC).
858 Causes incompatibility with 1.0 protocol. Protocol TODO #7.
859 Affected file is lib/silccore/silcchannel.c.
861 * Fixed the SKE to save the remote version, since the
862 silc_ske_parse_version mistakenly checked wrong version,
863 after it replaced the start payload. Affected files are

887 need the SilcSocketConnection which should not be visible
888 to application. Affected files are lib/silcclient/client.c
889 and lib/silcclient/silcclient.h.
891 * Rewrote the text for Private Message Key Payload in the
892 protocol specification. Protocol TODO #11.

911 the `notify' client operation.
913 * Fixed the Max Argument fields that had too large value set
914 in the protocol specs. Protocol TODO #14.
916 * Added the LEAVE command reply to return the ID of parted
917 channel. Updated protocol specs and implemented it to the
918 client and server. Protocol TODO #15. Affected files are
919 silcd/command.c, lib/silcclient/command_reply.c. The channel
920 entry is now returned to application in the `command_reply'

930 file is silcd/command.c.
932 * Defined new message flags SILC_MESSAGE_FLAG_REPLY to be
933 generic reply to a generic request (REQUEST flag), and
934 SILC_MESSAGE_FLAG_DATA to send any kind of data in a generic
935 way. A draft-riikonen-silc-flags-payloads-00.txt is written
936 to define the payload for DATA flag. Added the flags to
937 the implementation. Protocol TODO #9. Affected file is

955 client to set these modes.
957 * Deprecated all administrative commands from SILC protocol
958 since they are highly implementation specific commands.
959 Updated protocol specs. Moved the old commands in
960 implementations to private range of command types. Affected
961 files are silcd/command.c, lib/silcclient/command.c and
962 lib/silcclient/command_reply.c. Protocol TODO #8.

980 Affected file silcd/protocol.c.
982 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
984 * Some client implementations quit network by doing first LEAVE
985 and then immediately SIGNOFF (like Bombyx). We now do check
986 after a short time after LEAVE notify and check whether the
987 client is still valid after LEAVE, and if not we remove it from
988 cache. Affected file is lib/silcclient/client_notify.c.
990 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>

1016 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
1018 * Changed the silc_get_username and silc_get_real_name to
1019 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
1021 * Fixed the Irssi SILC Client to use the silc_get_username and
1022 silc_get_real_name insted of glib routines since the glib
1023 routines only corrupt stack. Fixes the Irssi SILC to work in
1024 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
1026 * Fixed the Irssi to not use g_get_home_dir since it crashes
1027 or returns garbage on cygwin and corrupts stack. Added function
1028 get_home_dir to Irssi routines. Affected files are
1029 irssi/src/core/misc.[ch] and irssi/src/core/core.c.

1067 from server.c to silcd.c since they are stricly related to
1068 the application activity.
1070 * Reverted a small part of the automatic ref/unref since
1071 it caused a double unref in some situations. Affected
1072 files are silcd/silcd.[ch], server.c, serverconfig.c.
1074 * Added some .cvsignore files in the lib directory.
1076 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1078 * Fixed silc_net_gethostbyaddr to correctly resolve by
1079 address. Affected file lib/silcutil/silcnet.c.
1081 * Fixed the notify relaying to client. The HMAC to be used
1082 with relayed packets ws wrong and caused decryption failure
1083 at the client end. Affected file is silcd/packet_receive.c.
1085 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1087 * Created new branch silc_protocol_1_0_branch.
1089 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
1091 * Changed the silc_server_config_* routines to be SilcServer
1092 independent. They are now officially application specific code
1093 and not part of generic server implementation. Affected files
1094 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
1096 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1098 * Added automatic referencing of config context in the
1099 silc_server_config_alloc, and automatic unreferencing in the
1100 silc_server_config_destroy. Affected files are
1101 silcd/serverconfig.[ch], silcd/silcd.c.
1103 * Fixed the silc_log_quick handling in the logging routines.
1104 It didn't log quickly when it was TRUE. Affected file is
1105 lib/silcutil/silclog.c. Also the flush delay was set even
1106 if it was 0 in config file. Affected file is
1107 silcd/serverconfig.c.
1109 * Added support for changing key pair of the server in rehash.
1110 Affected file silcd/server.c.
1112 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1114 * Fixed the TOPIC_SET notify to not cras. It changed the topic
1115 too early, before getting the channel entry. Affected file
1116 is silcd/packet_receive.c.
1118 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1120 * Added functions silc_server_config_[ref/unref], these are used
1121 to prevent that the config object is destroyed.
1123 No longer directly affect global variables silc_log_quick and
1124 silc_log_delay, they are first cached inside the config object
1125 and then applied with silc_server_config_setlogfiles().
1127 silc_server_config_set_defaults() is now internal to
1128 serverconfig.c, there are no reasons to show this internal stuff
1131 Affected files are silcd/serverconfig.[ch].
1133 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
1134 fprintf's to stderr, since some code may be executed again after
1135 the server went into the background. Affected files are
1138 * Added rehash support. Added function silc_server_rehash() that
1139 will perform all the basic tasks of the rehashing procedure.
1141 * Added command line option `-x, --hexdump'. This will enable the
1142 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
1143 The option `--hexdump' implies `--debug'.
1145 * Fixed a bad bug in the logging APIs (silcutil library) where
1146 the application would crash after calling silc_log_reset_all().
1148 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1150 * Fixed the KICKED notify handling in client library to
1151 correctly remove the channel and all entries from the
1152 channel when I was kicked. This bug crashed the client.
1154 Fixed yet another but in KICKED notify handling to remove
1155 the kicked client correctly from the channel.
1157 Affected file is lib/silcclient/client_notify.c.
1159 * Fixed a minor bug in looking up correct client entry
1160 in KICKED notify in server. Affected file is
1161 silcd/packet_receive.c.
1163 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
1164 sources correctly to distribution. Fixes --with-gmp option.
1166 * Removed the manual rehashing from ID Cache, and changed it
1167 to use the SILC Hash Table's auto rehash feature. Affected
1168 file is lib/silccore/silcidcache.c.
1170 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1172 * Fixed a bug in the silc_client_nickname_format function that
1173 handles the multiple same nickname formatting. Two clients
1174 with same nickname caused problems after the first one left
1175 and rejoined. It didn't format the nickname correctly.
1176 Affected file is lib/silcclient/idlist.c.
1178 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1180 * Don't change the topic if olod topic is same as new one.
1181 Affected file is silcd/packet_receive.c.
1183 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1185 * Added cross-reference support to the SILC Documentation
1186 generator. All types across all HTML files are now cross-
1187 referenced. Affected files util/robodoc/generator.c and
1188 scripts/silcdoc/silcdoc.
1190 * Added file lib/silcutil/silctypes.h to include all the
1191 arithmetic type definitions and some macros. Removed
1192 includes/bitmove.h and moved macros to silctypes.h.
1194 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1196 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
1198 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1200 * Added `type' argument to silc_id_payload_parse_id function which
1201 now returns the type of the ID to the sent pointer. Affected
1202 file is lib/silccore/silcid.[ch].
1204 * Added check for CMODE_CHANGE notify type that mode change is
1205 allowed by the sender. Affected file silcd/packet_receive.c.
1207 * Added check for CUMODE_CHANGE notify type that mode change is
1208 allowed by the sender. Affected file silcd/packet_receive.c.
1209 Added the ID type as CUMODE_CHANGE notify type as argument
1210 to the `notify' client operation. Affected files are
1211 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
1213 * Added function silc_client_add_server to the client library.
1214 Added support for resolving also channel and server info when
1215 received unknown entity in notify packet. Affected files are
1216 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
1218 * Added function silc_command_get_status to return the command
1219 status from the command reply's argument payload. Affected files
1220 are lib/silccore/silccommand.[ch].
1222 * Added check for KICKED notify type that the kicking is
1223 allowed by the client. Affected file silcd/packet_receive.c.
1225 * Created function silc_get_input which can be used to get input
1226 (echo on or off) from user on command line. Affected files are
1227 lib/silcutil/silcutil.[ch].
1229 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1231 * Optimized silc_server_packet_relay_to_channel function.
1232 Added new function silc_channel_message_payload_encrypt which
1233 can be called directly if channel message payload needs to
1234 be encrypted and is already encoded (no need to call _encode
1235 function). Packet relaying is now done by router without any
1236 extra memory allocations. Affected files are
1237 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
1238 silcd/packet_send.c.
1240 * Fixed the INVITE notify handling. It took wrong arguments
1241 as invite list and invite delete. Affected file is
1242 silcd/packet_receive.c.
1244 * Added check for TOPIC_SET notify type that the topic change is
1245 allowed by the client. Affected file silcd/packet_receive.c.
1247 * Added check for INVITE notify type that inviting is allowed by
1248 the client. Affected file silcd/packet_receive.c.
1250 * Changed the silc_server_client_on_channel to return the
1251 SilcChannelClientEntry as well. Moved the function
1252 silc_server_check_cmode_rights to server_util.[ch].
1253 Affected files are silcd/server_util.[ch], silcd/command.c.
1255 * Added function silc_server_check_umode_rights to check whether
1256 changing client's user mode is allowed. Added check for
1257 UMODE_CHANGE notify type that the umode change is allowed
1258 by the client. Affected files are silcd/server_util.[ch],
1259 silcd/packet_receive.c and silcd/command.c.
1261 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1263 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
1264 ID length. It ignored that ID can be IPv6 based as well.
1265 Affected file lib/silccore/silcpacket.h.
1267 * Fixed the silc_id_id2str and silc_id_str2id to take the
1268 IPv6 address offset's into consideration. Affecte file is
1269 lib/silccore/silcid.c.
1271 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1273 * Fixed the internal Unix scheduler functions to check for
1274 NULL context they may receive. The affected file is
1275 lib/silcutil/unix/silcunixschedule.c.
1277 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
1279 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
1280 can specify different directory with --home command line
1281 parameter. Affected files irssi/src/silc/core/client_ops.c,
1284 * SILC-specific commands aren't now executed if the active server
1285 isn't of SILC-type, so there won't be problems with having
1286 IRC and SILC protocol support in same client. Affected files
1287 irssi/src/silc/core/silc-channels.c, silc-servers.c,
1290 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1292 * Improved the signal support in SILC Schedule. Added new
1293 function silc_schedule_signal_call which is used by application
1294 to mark a signal to be called. It is now safe to perform
1295 any kind of tasks in signal callbacks since it is guaranteed
1296 that the application specified signal callback is called
1297 after the signal is over. Affected files are
1298 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
1300 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1302 * Added `name' field to SilcChannelPrivateKey to represent
1303 application given name for the key. Moved also the context from
1304 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
1305 Added the `name' argument also to the function
1306 silc_client_add_channel_private_key.
1308 Added function silc_client_current_channel_private_key to set the
1309 current channel private key in use.
1311 Added "change" command to KEY command which can be used to change
1312 the current channel private key. Bound the command also to
1313 alt+K (Alt+Shift+k).
1315 Also affected files lib/silcclient/client_channel.c,
1316 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
1318 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1320 * Added silc_rng_get_byte_fast function in to the
1321 lib/silccrypt/silcrng.[ch].
1323 * Changed the interface of silc_packet_assemble and the
1324 silc_packet_send_prepare. If silc_packet_assmble is now
1325 called the application does not call silc_packet_send_prepare
1326 because the library will call it automatically. These
1327 interfaces now also return a reference to the outgoing buffer
1328 which includes the assembled packet, which the application can
1329 use to encrypt the packet.
1331 Affected files are lib/silccore/silcpacket.[ch],
1332 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
1333 silcd/packet_send.c, server_backup.c and packet_receive.c.
1335 * Fixed a packet sending bug on very high load, where outgoing
1336 packet queue wasn't handled correctly and packets got corrupted.
1337 Affected files are lib/silcutil/*/silc*sockconn.c,
1338 lib/silcclient/client.c and silcd/server.c.
1340 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1342 * Added macro SILC_PACKET_DATALEN which can be used during
1343 packet assembling to check whether the data to be added to
1344 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
1345 len is truncated until it fits it.
1347 Added checks for maximum length of channel message payload and
1348 private message payload also.
1350 Added checks for maximum packet length in server and in
1353 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
1354 lib/silcclient/client.c, lib/silccore/silcchannel.c and
1355 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
1356 lib/silcclient/client_prvmsg.c.
1358 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1360 * Added silc_server_packet_queue_purge call to the
1361 silc_server_disconnect_remote to assure that all data in the
1362 queue before disconnecting is sent to the network. Affected
1363 file silcd/server.c.
1365 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1367 * Added the deleting of server's own ID cache entry to the
1368 silc_server_free function. Free also everything else that
1369 has been allocated in silc_server_init. The affected file
1372 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1374 * Added functions silc_parse_version_string, silc_version_to_num,
1375 and silc_ske_parse_version to parse SILC protocol style version
1376 strings. Affected files lib/silcutil/silcutil.[ch] and
1377 lib/silcske/silcske.[ch].
1379 * Added new configuration params: version_protocol, version_software
1380 and version_software_vendor to specify what version the remote
1381 host must at least be to be able to connect to server. The vendor
1382 string can be regex matched too. Added new function
1383 silc_server_connection_allowed to check maximum number of allowed
1384 connections, and allowed versions for incoming connections.
1385 Affected files are silcd/server.c, server_util.[ch] and
1388 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1390 * Added preliminary support for signals in scheduler. The
1391 signals we care about are now blocked always when the scheduler
1392 is locked. This way we can synchronise the use of signal with
1393 scheduler. It is guaranteed that when signal occurs the scheduler
1394 is not locked, and thus new tasks can be safely added to the
1397 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
1398 to silc_schedule_internal_init and silc_schedule_internal_uninit.
1399 Added new platform specific routines
1400 silc_schedule_internal_signals_[un]block and
1401 silc_schedule_internal_signal_[un]register.
1403 Added new functions to SILC Schedule API:
1404 silc_schedule_signal_[un]register. Each signal that application
1405 is going to use should be registered to the scheduler.
1407 Affected files are lib/silcutil/silcschedule.[ch],
1408 lib/silcutil/*/silc*schedule.c.
1410 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1412 * Check for unauthenticated client and server in the
1413 silc_server_new_client and silc_server_new_server functions.
1414 Affected file silcd/packet_receive.c.
1416 * Added function silc_string_is_ascii to check whether given
1417 string is 7-bit ASCII string. Affected files are
1418 lib/silcutil/silcutil.[ch].
1420 * Added function silc_id_is_valid_server_id into the
1421 silcd/serverid.c and added checking for valid Server ID's in
1422 silc_server_new_server. The Server ID must always be based
1423 on the server's public IP address.
1425 * Added logging of DISCONNECT packet message in the server.
1426 Affected file silcd/server.c.
1428 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1430 * Changed all library interfaces that use Global RNG to also
1431 accept SilcRng as argument. Affected files are
1432 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
1433 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
1434 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
1435 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
1436 lib/silccrypt/rsa.c.
1438 * Added function silc_pkcs_generate_key to the
1439 lib/silccrypt/silcpkcs.[ch] for applications so that they
1440 don't need to do pkcs->pkcs->init calls anymore.
1442 * Remove SilcSocketConnection from the SFTP API since it really
1443 wasn't needed there. The application has the information
1444 saved in its contexts anyway and the SFTP layer doesn't need
1445 know about it. Affected files lib/silcsft/silcsftp.h and
1446 lib/silcsftp/sftp_[server/client].c.
1448 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
1449 The SilcSimContext is not SilcSim.
1451 * Fixed possible buffer overflows in silc_id_render in the
1452 lib/silcutil/silcutil.c.
1454 * On EPOC the global crypto module lists are not used at all
1455 in the crypto library. Added support for using the constant
1456 algorithm list on EPOC. Affected files are
1457 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
1460 * Fixed the handling of third parameter of KICKED notify, since
1461 it was mistakenly updated to SILC Protocol 1.0 even though it
1462 is to be included in 1.1. Since it is not in 1.0 it is not
1463 mandatory, and this fix now handles it only if it is provided,
1464 and it is not error if it is not provided. Affected file
1465 lib/silcclient/client_notify.c.
1467 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1469 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
1470 client. Affected file irssi/src/silc/core/client_ops.c.
1472 * Merged with Irssi 0.8.4 from irssi.org CVS.
1474 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1476 * Check for valid socket connection in client entries before
1477 sending any messages. Fixes a crash, but doesn't fix some
1478 other underlaying bug that is lurking there. Affected
1479 file silcd/packet_send.c.
1481 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
1483 * $usermode, $cumode and $cumode_space expandos shouldn't do
1484 anything with non-SILC server records. Affected file
1485 irssi/src/silc/core/silc-expandos.c
1487 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1489 * Fixed the silc_net_check_[host/local]_by_sock to support
1490 IPv6 bound sockets as well. Now they can return IPv6 addresses
1491 as well. Affected file lib/silcutil/silcnet.c.
1493 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
1494 Affected lib/silcutil/unix/silcunixnet.c.
1496 * Fixed ID rendering (at least on some platforms, not NetBSD)
1497 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
1499 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1501 * Added silc_hash_public_key and silc_hash_public_key_compare
1502 functions to be used with SilcHashTable. They can be used to
1503 hash public keys and compare public keys in hash table. Affected
1504 file lib/silcutil/silcutil.[ch].
1506 * Added support for specifying multiple public keys for Client
1507 connection section in server configuration file. This makes it
1508 possible to accept multiple public keys from same host, or to
1509 make a section that accepts any incoming host, and have the
1510 accepted public keys listed in the section.
1512 Added functions silc_sever_[find/get]_public_key, added the
1513 support for this actually to all connection sections but only
1514 the Client section is currently allowed to specify multiple
1517 Affected files are silcd/server.c, server_internal.h,
1518 command.c, protocol.c, server_util.[ch], packet_receive.c.
1520 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1522 * Merged Irssi 0.8.2 from irssi.org CVS.
1524 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1526 * If silc_debug is TRUE, also output standard logging messages
1527 to stderr with the debug output.
1529 Made silc_log_reset_all() flushing all channels before returning.
1530 Also fixed some documentation typos.
1532 Affected files are lib/silcutil/silclog.[ch].
1534 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1536 * Fixed the server to check correctly the amount of connections
1537 from single host, by checking also the type of the connection.
1538 Fixed also the comparison of number of connections and number
1539 of allowed connections. Affected files are silcd/server.c,
1542 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1544 * Fixed the USERS command reply to save the user's mode on the
1545 channel as well. Fixed JOIN command reply to check whether a
1546 client is on channel already and not join it twice. Affected
1547 file lib/silcclient/command_reply.c.
1549 * Added new file silc-expandos.c into irssi/silc/core/ to return
1550 various stuff for various signal for the statusbar etc. updating.
1551 Now Irssi SILC client prints channel user modes etc. on the
1554 * The user mode (like server/router operator changes) is now shown
1555 on the Irssi SILC client's statusbar. The affected files are
1556 irssi/src/silc/core/client_ops.c, silc-expandos.c.
1558 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1560 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c

1621 application does not need to define them. Affected file
1622 includes/silcincludes.h.
1624 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
1625 old name went against naming convention. Applications now
1626 include "silcclient.h" instead of "clientlibincludes.h".
1627 Removed includes/clientlibincludes.h, it is redundant now.
1629 * Renamed includes/version.h to silcversion.h.
1631 * Added really preliminary support for OS/2 into the util

1689 the SKE interface a bit.
1691 * Fixed padding problem in PKCS#1. The padding was not actually
1692 random since the random number generator was used incorrectly.
1693 This security bug affects only when encrypting with PKCS#1, and
1694 it is not currently used at all in SILC. SILC only use signing
1695 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.

1759 irssi/src/fe-text/silc.c.
1761 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1763 * Added new configuration options and blocks:
1764 keepalive_secs, reconnect_count, reconnect_interval,
1765 reconnect_interval_max, reconnect_keep_trying and

1780 the connection configuration object from the SilcServerConnection
1781 object instead of finding it during the connecting phase.
1782 Added the configuration object to SilcServerConnection struct.
1783 Affected files silcd/server_internal.h, server.c.
1785 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1787 * Add the client on channel after it was resolved at the
1788 channel message receiving, and it was not already on the
1789 channel. Affected file lib/silcclient/client_channel.c.

1811 public key is set. If not set, public key is preferred.
1812 This has effect only when being initiator (responder will try
1815 Added support for authentication with passphrase and public key
1816 at the same time. The passphrase is tried first always since
1817 it is faster to check.
1819 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
1821 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

1868 zero port also if the hostname is NULL because it could not
1871 Call file transfer monitor callback now also if error occurs
1872 during key agreement protocol.
1874 Changed the silc_client_file_send interface to return the
1875 SilcClientFileError instead of session id. The session ID
1876 is returned into pointer provided as argument.

1948 * Fixed a bug in hash table tarversing. While the hash table
1949 is traversed with SilcHashTableList the table must not be
1950 rehashed. It is now guaranteed that auto rehashable tables
1951 are not rehashed while tarversing the list. Also defined that
1952 silc_hash_table_rehash must not be called while tarversing
1953 the table. Added function silc_hash_table_list_reset that must
1954 be called after the tarversing is over. The affected files are
1955 lib/silcutil/silchashtable.[ch].
1957 * Changed all hash table traversing to call the new
1958 silc_hash_table_list_reset in server and in client library.
1960 * Added function silc_client_on_channel to return the
1961 SilcChannelUser entry if the specified client entry is joined

1976 * When sending JOIN command to router for processing the
1977 sender's old command identifier was not saved back to the
1978 sender's command context, fixed now. The affected file is
1981 * Create the key in JOIN command of the router did not return
1982 the channel key, added check for this. Affected file is
1985 * Fixed a channel ID update bug in JOIN command reply. Do
1986 not directly upgrade the ID but call the function
1987 silc_idlist_replace_channel_id if the ID was changed.
1988 Affected file silcd/command_reply.c.
1990 * Fixed memory leaks from command calling if it would fail.

2088 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2090 * Removed the SilcClientCommandDestructor from the client
2091 libary, it is not needed anymore. Affected files are
2092 lib/silcclient/silcapi.h, command[_reply].[ch],
2093 client_notify, idlist.c.
2095 * Fixed GETKEY command to first resolve client, and then
2096 resolve the server only if the client was not found, instead
2097 of resolving both at the same time. Affected file is
2098 lib/silcclient/command.c.
2100 * Added silc_client_start_key_exchange_cb and lookup the
2101 remote hostname and IP address before starting the key
2102 exchange with server. The affected file is
2103 lib/silcclient/client.c.
2105 * The server's public key is now saved using the IP address
2106 of the server and not the servername for the filename.
2107 The hostname public key filename is checked as an fall back
2108 method if the IP address based filename is not found.
2110 Fixed the GETKEY command to save the fetched server key
2111 in correct filename.
2113 Print the remote server's hostname now when new key is
2114 received during connection process. Affected file is
2115 irssi/src/silc/core/client_ops.c.
2117 * Return always our own public key to the client if it asks
2118 for it with GETKEY command. Affected file silcd/command.c.
2120 * Removed the use_auto_addr variable from default config
2121 file since it was in wrong section. Affected file is
2124 * Fixed TOPIC_CHANGE notification to not route it when it
2125 was sent using silc_server_send_notify_to_channel function.
2126 Affected file silcd/command.c.
2128 * Fixed silc_server_send_notify_kicked to send the kicker's
2129 Client ID also, it was missing. Affected files are
2130 silcd/command.c, silcd/packet_send.[ch].
2132 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2134 * Do not save client history information in SERVER_SIGNOFF.
2135 Fixes the bug in normal server that it does not detect
2136 the client becoming valid after the server becomes back
2137 online. Affected file silcd/server_util.c.
2139 * Added `sock_error' field into the SilcSocketConnection
2140 context. When error occurs during socket operation (read
2141 or write) the error is saved. Added also new function
2142 silc_socket_get_error to return human readable socket error
2143 message. Affected files are lib/silcutil/silcsockconn.[ch],
2144 lib/silcutil/unix/silcunixsockconn.c, and
2145 lib/silcutil/win32/silcwin32sockconn.c.
2147 * The server now prints the socket error message in the
2148 signoff for client. Affected file silcd/server.c.
2150 * Fixed the `created' channel information sending from router
2151 to server in JOIN command. Checks now whether the channel
2152 really was created or not and set it according that.
2154 Fixed the JOIN command to use the client entry's current
2155 ID during the joining procedure instead of the one it sent
2156 in the command (it is checked though), since it can change
2157 between the packet processing and command processing, and
2158 would just case unnecessary pain in the client end. Affected
2159 file silcd/command.c.
2161 * Fixed a channel key payload sending to use correct channel
2162 ID when the server was forced to change the channel's ID by
2163 router. Router sent the key payload with the old Channel ID.
2164 Affected file silcd/packet_receive.c.
2166 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2168 * Call silc_server_save_channel_key only if the key payload
2169 was provided in the JOIN command's command reply. Affected
2170 file silcd/command_reply.c.
2172 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2174 * Fixed silc_mp_sizeinbase to return the value correctly with
2175 MPI. Affected file lib/silcmath/mp_mpi.c.
2177 * Fixed the stop_server signal to correctly stop the scheduler
2178 and gracefully stop the server when SIGTERM or SIGINT signals
2179 are received. Affected file silcd/silcd.c.
2181 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
2183 * Simple handling of TERM and HUP signals. Also added some log
2184 flushing call around. Affected file is
2187 * Fixed small bugs in silclog.c. Now buffering output will take
2188 effect after 10 seconds since startup: This will ensure that
2189 no important startup messages are lost. Also output redirection
2190 will preserve original format ([Date] [Type] message).
2191 Affected file is lib/silcutil/silclog.c.
2193 * Added two options to the config file, in the logging section:
2194 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
2195 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
2197 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2199 * Do not print the warning about log files not being initialized
2200 more than once to avoid excess logging. Affected file is
2201 lib/silcutil/silclog.c.
2203 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
2204 the SIM copying in make install in Makefile.am.pre.
2206 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2208 * Rewritten silclog APIs. Globally interesting changes follows:
2209 silc_log_set_files() changed to silc_log_set_file().
2210 silc_log_set_callbacks() changed to silc_log_set_callback().
2211 ROBOdoc documented silclog header file.
2212 SilcLogCb now returns bool to wether inihibit the default
2213 handler or not (to keep the old behaviour return always TRUE).
2214 The new APIs should also fix the problem of the
2215 silcd_error.log file that was written in the current directory.
2218 Log files streams will remain opened after silc_log_set_file()
2219 call, means less CPU usage notably on high traffic servers.
2220 File streams are now full buffered, and flushed to the disk
2221 every 5 minutes, lesses HD activity and CPU usage.
2222 Messages can be redirected, allowing admins to configure
2223 one single logfile for all server messages.
2224 the silc_log_quick global variable to activate fast-logging.
2225 Affected files lib/silcutil/silclog.[ch]
2227 * Changed some code to conform new silclog APIs. Affected
2228 files are doc/example_silcd.conf.in, silcd/server.c
2229 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
2232 * Fixed a memory leak that could occur in some situations.
2233 Affected file silcd/serverconfig.c.
2235 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2237 * Added the silc_client_del_client to remove the client from
2238 all channels as well. Affected file lib/silcclient/idlist.c.
2240 * Fixed the client library to correctly remove the client
2241 from all channels when the client entry is being destroyed.
2242 Affected file lib/silcclient/client_notify.c, command.c.
2244 * Added auto-nicking support to the client library. If the
2245 applicatio now sets client->nickname it will be sent to the
2246 server after connecting by the library. This way for example
2247 SILCNICK (or IRCNICK) environment variables will have effect
2248 and always change the nickname automatically to whatever
2249 it is wanted. Affected file lib/silcclient/client.[ch].
2251 * Renamed silc_server_command_bad_chars to the
2252 silc_server_name_bad_chars and moved it to the
2253 silcd/server_util.[ch]. Added also new function
2254 silc_server_name_modify_bad to return nickname that
2255 includes bad characters as new nickname without those
2256 bad characters. This check and modify is now used in
2257 silc_server_new_client when the username is initially set
2258 as nickname, so it must be checked to be valid nickname.
2259 Affected file silcd/packet_receive.c.
2261 * The nickname length is now taken from the packet for real
2262 and not trusted to strlen() since it clearly can return
2263 wrong length for nickname including bad characters. This
2264 also applies to channel names. Affected file silcd/command.c.
2266 * Removed the lib/silcsilm/modules directory. Modules are now
2267 compiled into the lib/silcsim. Fixed the copying of the
2268 modules to follow symbolic links in Makefile.am.pre.
2270 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2272 * Fixed silc_string_regexify list creation. Fixes bugs with
2273 BAN and INVITE commands in server. The affected file is
2274 lib/silcutil/unix/silcunixutil.c.
2276 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2278 * Removed the command destructor entirely from the server's
2279 command and command reply routines. It is not needed, and
2280 its usage was buggy and caused crashes. Affected files are
2281 silcd/command[_reply].[ch].
2283 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2285 * Cancel protocol and NULL sock->protocol if timeout
2286 occurred during protocol. Affected file silcd/server.c.
2288 * Cancel protocol timeouts always before calling the final
2289 callback, to assure that after final callback is called
2290 no other state will be called for the protocol anymore.
2291 Affected file silcd/protocol.c.
2293 * Print error log if incoming connection configuration could
2294 not be found. Affected file silcd/server.c.
2296 * Fixed JOIN command to correctly save the founder mode
2297 to the client on normal SILC server, when the channel
2298 was created by the router. Affected file silcd/command.c.
2300 * Fixed LIST command (hopefully) to send correct reply
2301 packets. Affected file silcd/command.c.
2303 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2305 * The silc_packet_receive_process now returns FALSE if the
2306 read data was invalid packet, and TRUE if it was ok.
2308 The server now checks that if unauthenticated connection
2309 sends data and its processing fails the server will close
2310 the connection since it could be a malicious flooder.
2312 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
2314 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2316 * Make sure the warning about error opening a log file is
2317 printed only once and not everytime it fails (produces
2318 too much useless log). Affected file lib/silcutil/silclog.c.
2320 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2322 * Made the silc_server_daemonise() function more readable.
2323 Affected file silcd/server.c.
2325 * Pid file is now optional, the user may comment it out from
2326 the config file. Removed define SILC_SERVER_PID_FILE, we
2327 don't need a default any longer. Affected file
2328 configure.in.pre, lib/Makefile.am.pre.
2330 * Make some use of the pid file. The server now dies at startup
2331 if it detects a valid pid file on his path. The server would
2332 die anyway in this circumstance, because of the bind() failure.
2333 Affected file silcd/silcd.c.
2335 * No longer compiling lib/dotconf.
2337 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2339 * Fixed JOIN command parsing not to crash. Affected file
2340 lib/silcclient/command.c.
2342 * Fied the NICK_CHANGE notify to add the new client entry
2343 even it is resolved. This removes an <[unknown]> nick
2344 thingy bug in the client. Affected file is
2345 lib/silcclient/client_notify.c.
2347 * Do not try to allocate 0 bytes (efence does not like it)
2348 in lib/silccore/silccomand.c when encoding payload.
2350 * Do not take IRCNICK as nickname in Irssi SILC client since
2351 it is not possible to set nickname before hand connecting
2352 the server (TODO has an entry about adding auto-nicking
2355 * Changed the silc_server_command_pending to check whether
2356 there already exists an pending entry with the specified
2357 command, command identifier and pending callback. This is
2358 to fix IDENTIFY and WHOIS related crashes that may register
2359 multiple pending commands with same identifier. Affected
2360 file silcd/command.c.
2362 * Fixed the server to reconnect to the router even if it
2363 was already reconnecting and EOF was received. This to
2364 fix a possibility that the server wouldn't ever try to
2365 auto-reconnect to the router. Affected file silcd/server.c.
2367 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2369 * Fixed the server's password authentication to use the
2370 length of the locally saved password, and not the one
2371 sent in the packet. Affected file silcd/protocol.c.
2373 * Fixed same password authentication problem in the
2374 Authentication Payload handling routines in
2375 lib/silccore/silcauth.c.
2377 * Yet another password authentication problem fixed with
2378 channel password handling in silcd/command.c.
2380 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2382 * If first character of string in silc_parse_userfqdn is '@'
2383 then do not parse it. Affected file is
2384 lib/silcutil/silcutil.c.
2386 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2388 * Fixed minor bug in IDENTIFY command reply sending, which
2389 caused various weird problems during JOIN when it was
2390 resolving names for users. Affected file silcd/command.c.
2392 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2394 * Fixed the IDENTIFY command reply sending to chech better valid
2395 clients. It was possible to send incomplete list of replies.
2396 Affected file silcd/command.c.
2398 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2400 * Added silc_client_command[s]_[un]register functions now to
2401 dynamically register the commands in client library. Removed
2402 the static table of commands. This allows the client library
2403 to call commands without causing the application to know about
2404 what commands library has called.
2406 Removed the INFO command reply kludge to detect when the command
2407 was called by library. Now library use its own command reply
2408 function for INFO command.
2410 Added function silc_client_command_call to call a command.
2411 Application can use it to call command, not access the structure
2414 Now all commands that are sent by the client library (not
2415 explicitly sent by application) use own command reply functions.
2417 Affected files around lib/silcclient/ and in
2418 irssi/src/silc/core/.
2420 * Fixed the WHOIS command reply sending to chech better valid
2421 clients. It was possible to send incomplete list of replies.
2423 Fixed the WHOIS and IDENTIFY to send the request to router
2424 if normal server did not do it and did not find any results.
2426 Affected file silcd/command.c.
2428 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2430 * Moved the internal data from SilcClient context into its
2431 own file, not accesible to application. Affected files
2432 lib/silcclient/client.h and lib/silcclient/client_internal.h,
2433 and other files in client library.
2435 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2437 * Added doc/examples installation target in Makefile.am.pre.
2440 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2442 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
2443 commands the found client entry will be removed from the
2444 cache, after notifying application about the error. Affected
2445 file lib/silcclient/command_reply.c.
2447 * Changed the /MSG to check for exact nickname user gave, and
2448 not let `nick' match `nick@host' if it is only one found. Now,
2449 user must type the exact nickname (like nick@host2) even if
2450 there are no more than one same nicks found. This is to avoid
2451 a possibility of sending nickname to wrong nickname since
2452 `nick' could match `nick@host'. Affected file is
2453 irssi/src/core/silc-servers.c.
2455 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2457 * Do not print "you are now server operator" or similar when
2458 giving /away command. Affected files are
2459 irssi/src/silc/core/client_ops.c, silc-servers.h.
2461 * Made the silc_server_command_pending_error_check to send
2462 the same command reply payload it received back to the
2463 original sender of the command. This way all arguments
2464 that was received by the server will be received by the
2465 client too. Affected file silcd/command.c.
2467 * Added the silc_idcache_add to return the created cache entry
2468 to a pointer. Affected file lib/silccore/silcidcache.[ch].
2470 * Add global clients to expire if they are not on any channel.
2471 This is because normal server will never know if they signoff
2472 if they are not on any channel. The cache expiry will take
2473 case of these entries. This is done by normal servers only.
2474 The affected files are silcd/command_reply.c,
2475 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
2477 * If server receives invalid ID notification for WHOIS or
2478 IDENTIFY and the ID exists in the lists, it is removed.
2479 Affected file silcd/command_reply.c.
2481 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
2482 in client then client entry that it matches is searched and
2483 the nickname is printed on the screen for user. Affected
2484 file irssi/src/silc/core/client_ops.c.
2486 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2488 * Use cache entry expire time in the LIST command reply to
2489 purge old entries from the cache after the LIST command
2490 reply has been received. This way we don't have non-existent
2491 entries in the cache for too long. Affected file is
2492 silcd/command_reply.c.
2494 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2496 * If we are normal server, and we've not resolved client info
2497 in WHOIS or IDENTIFY from router, and it is global client,
2498 we'll check whether it is on some channel. If it is not
2499 then we cannot be sure about its validity and will resolve it
2500 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
2501 file silcd/command.c.
2503 * Search channel by name (if possible) rather than by ID
2504 in IDENTIFY command's command reply. Affected file is
2505 silcd/command_reply.c.
2507 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2509 * Distribute to the channel passphrase in CMODE_CHANGE notify.
2510 Updated specs and implemented it. Affected file silcd/command.c,
2511 silcd/packet_send.c and silcd/packet_receive.c.
2513 * Implemented the <founder auth> payload handling in the JOIN
2514 command. If provided all conditions for channel joining
2515 except requirement to provide correct passphrase can be
2516 overrided by the channel founder. Updated the protocol specs.
2517 Affected file silcd/command.c.
2519 Added support for founder auth in JOIN command in client
2520 library. Fixed the parsing of the JOIN command now to support
2521 all options as they should be. The affected file is
2522 lib/silcclient/command.c.
2524 * Optimized the WHOIS and IDENTIFY commands to send the request
2525 to router only if it includes nicknames or other names. If
2526 they include only IDs then check the local cache first before
2527 routing. Affected file is silcd/command.c.
2529 * Added channels topic announcements. Affected file is
2530 silcd/packet_receive.c and silcd/server.c.
2532 * Fixed the silc_server_send_notify_topic_set to really destine
2533 the packet to channel. Affected file silcd/packet_send.c.
2535 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
2536 library. Affected file lib/silcclient/client_notify.c.
2538 * Added UMODE announcements. Affected file silcd/server.c.
2540 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2542 * Memory leak fixes in:
2544 lib/silcutil/silcsockconn.c
2545 lib/silcske/silcske.c
2546 lib/silcske/groups.c
2548 lib/silccrypt/silcpkcs.c
2549 lib/silccore/silccommand.c
2550 lib/silccore/silcidcache.c
2555 * ROBOdoc documented the lib/silcske/groups.h file and a
2556 bit changed the interface for better.
2558 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2560 * Update the client entry context in the ID cache after
2561 nick change. Affected file lib/silcclient/command.c.
2562 Fixes the CUMODE command when regaining founder privileges,
2563 and a little WHOIS problem.
2565 * Fixed silc_net_gethostbyname to correctly call the
2566 inet_ntop. Affected file lib/silcutil/silcnet.c.
2568 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2570 * Added IPv6 support checking to the configure.in.pre, added
2571 also --enable-ipv6 option to override the check. Affected
2572 file configure.in.pre.
2574 * The silc_thread_create now calls the start function
2575 directly if threads support is not compiled in. Removes
2576 ugly #ifdef's from generic code. Affected files are
2577 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
2579 * Added silc_net_gethostby[name/addr]_async to asynchronously
2580 resolve. Affected files are lib/silcutil/silcnet.[ch].
2582 * Added support for rendering IPv6 based server, client and
2583 channel IDs. Affected file lib/silcutil/silcutil.c.
2585 * Added support for creating IPv6 based server IDs. Affected
2586 file is silcd/serverid.c.
2588 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2590 * Added silc_net_gethostby[addr/name] into the
2591 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
2592 routines. Added silc_net_is_ip[4/6]. Affected file is
2593 lib/silcutil/unix/silcunixnet.c. All routines that take
2594 address as argument now supports both IPv4 and IPv6 addresses.
2596 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2598 * Fixed LIST command reply sending in server. Affected file
2601 * Server now sends the kicker's client ID in the KICK notify
2602 to the kicked client. Affected file silcd/command.c.
2604 * The client library now parses the kickers client ID and
2605 UI displays it. Affected files lib/silcclient/client_notify.c
2606 and irssi/src/silc/core/silc-channels.c, module-formats.c.
2608 * Made all payload parsing function prototypes consistent.
2609 They all take now const unsigned char * and uint32 pair as
2610 the payload data instead of SilcBuffer. Changes all around
2611 the source tree. Other unsigned char* -> const unsigned char*
2612 changes around the tree as well.
2614 * Optimized SFTP client and server packet sending not to
2615 allocate new buffer for each packet but to recycle the
2616 first allocated buffer. Affected files are
2617 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
2619 * Optimized the SFTP client to use SilcList instead of
2620 SilcDList for requests, because it is faster. Affected file
2621 is lib/silcsftp/sftp_client.c.
2623 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
2624 into lib/silccore/silcid.[ch].
2626 Renamed silcpayload.[ch] into silcargument.[ch].
2628 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2630 * If client entry is deleted with active key agreement
2631 session, abort the session.
2633 The silc_client_abort_key_agreement now calls the completion
2634 callback with new SILC_KEY_AGREEMENT_ABORTED status.
2636 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
2639 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2641 * Don't use __restrict in older GCC's. Affected file is
2642 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
2644 * silc_net_localhost now attempts to reverse lookup the
2645 IP/hostname. Affected file lib/silcutil/silcnet.c.
2647 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
2648 command. It can be used to gain founder privileges at
2649 the same time when joining the channel.
2651 Defined that the SILC_NOTIFY_TYPE_KICKED send the
2652 kicker's client ID as well. Updated protocol specs.
2654 Defined that the server must send SILC_COMMAND_IDENTIFY
2655 command reply with error status to client who sent
2656 private message with invalid client ID.
2658 Updated the protocol specification.
2660 * Added silc_server_send_command_reply to send any
2661 command reply. Affected file silcd/packet_send.[ch].
2663 * Added silc_id_payload_encode_data to encode ID payload
2664 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
2666 * The server now send IDENTIFY command reply with error
2667 status if client ID in private message is invalid. Affected
2668 file silcd/packet_receive.c.
2670 * Save the server key file with server's IP address in
2671 the filename instead of hostname. The affected file is
2672 irssi/src/silc/core/client_ops.c.
2674 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2676 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
2679 * Added libtool support for compiling shared objects in
2680 lib/silcsim. Affected file configure.in.pre and
2681 lib/silcsim/Makefile.am. Original patch by cras.
2683 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2685 * Pid file configuration, and server's config file fixes
2686 patch by toma. Updated CREDITS file.
2688 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2690 * Fixed silc_client_channel_message to not try to decrypt
2691 the message twice if it resolved the destination client
2692 information. This could cause of dropping one channel
2693 message. Affected file lib/silcclient/client_channel.c.
2695 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2697 * Added silc_client_run_one into lib/silcclient/silcapi.h and
2698 lib/silcclient/client.c. This function is used when the SILC
2699 Client is run under some other scheduler, or event loop or
2700 main loop. On GUI applications, for example this may be
2701 desired to used to run the client under the GUI application's
2702 main loop. Typically the GUI application would register an
2703 idle task that calls this function multiple times in a second
2704 to quickly process the SILC specific data.
2706 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2708 * Fixed silc_server_drop() for dropping the supplementary
2709 groups as well, this could cause a security hole on some
2712 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2714 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
2717 * Write PID file after dropping privileges. Added -F option
2718 to run server on foreground. A patch by debolaz.
2719 Affected files silcd/server.c, silcd/silcd.c.
2721 * Fixed MOTD to return the MOTD file server name. Affected
2722 file silcd/command.c.
2724 * Added INFO command reply handling to the Irssi SILC Client.
2725 Affected file irssi/src/silc/core/client_ops.c.
2727 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2729 * Fixed the silc_idcache_list_* routines to really support
2730 the dynamic list. Fixes a crash. Affected file is
2731 lib/silccore/silcidcache.c.
2733 * Fixed the LIST command reply to really call LIST command's
2734 pending callbacks. Affected file silcd/command_reply.c.
2736 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2738 * Update conn->local_entry->nickname after giving NICK
2739 command. Affected file lib/silcclient/command.c.
2741 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
2743 * Added the [pid] option to the silcd configuration file
2745 Affected files: serverconfig.[ch] and silcd.c
2747 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2749 * Save fingerprint in WHOIS command reply in server.
2750 Affected file silcd/command_reply.c.
2752 * Fixed NICK commands pending callback registration.
2753 Affected file lib/silcclient/command.c.
2755 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2757 * Use ++server->cmd_ident when sending commands in server,
2758 instead of random number. Affected file silcd/command.c.
2760 * Fixed GETKEY command reply to call actually GETKEY pending
2761 command callbacks. Affected file silcd/command_reply.c.
2763 * A bit stricter check for nicknames. Check for same nickname
2764 in NICK command also. Affected file silcd/command.c.
2766 * Do not call INFO command everytime client ID changes, only
2767 during first connecting. Affected file lib/silcclient/client.c.
2769 * Set the new nickname only after successful command reply for
2770 NICK command is returned by server. Affected file
2771 lib/silcclient/command.c.
2773 * Remove nicknames from nicklist during server_signoff notify.
2774 Should fix /NAMES bit more. The affected file is
2775 irssi/src/silc/core/silc-channels.c.
2777 * Added `fingerprint' field to the SilcIDListData in the
2778 silcd/idlist.h to hold the fingerprint of the client's
2781 Send the fingerprint of the client's public key in WHOIS
2784 Affected files silcd/command.c, and silcd/idlist.[ch].
2786 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
2787 create fingerprint from given data.
2789 * Show the fingerprint of the client's public key in WHOIS.
2790 Affected files irssi/src/module-formats.[ch] and
2791 irssi/src/silc/core/client_ops.c.
2793 * Format the multiple same nicknames also during JOIN and
2794 NICK_CHANGE notifys. Affected file is
2795 lib/silcclient/client_notify.c.
2797 * Do not print error on screen for invalid private message
2798 payload since it can come if someone is sending private
2799 messages with wrong key. Affected file
2800 lib/silccore/silcprivate.c.
2802 * Fixed multiple concurrent /PING crash. Affected file
2803 lib/silcclient/command.c.
2805 * Changed the wrong ID encoding. All IP addresses must be
2806 in MSB first order in encoded format. They were encoded
2807 wrong and was in LSB format. Affected files are
2808 silcd/serverid.c, lib/silcutil/silcutil.c.
2810 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
2812 * Call the `connect' client operation through the scheduler
2813 in case of error. Affected file lib/silcclient/client.c.
2815 * Call the `failure' client operation even if the error
2816 occurred locally during a protocol. Affected file is
2817 lib/silcclient/protocol.c.
2819 * Added support of sending LIST command to router from normal
2820 server. This way normal server can get list of all channels
2821 in the network too. Fixed the channel list sending in the
2822 server too. Affected files are silcd/command.c, and
2823 silcd/command_reply.[ch].
2825 * Added silc_server_update_channels_by_server and
2826 silc_server_remove_channels_by_server. They are used during
2827 disconnection of primary router and in backup router protocol.
2828 Affected file silcd/server_util.[ch], silcd/server.c and
2829 silcd/server_backup.c.
2831 * Fixed channel adding to global list in IDENTIFY command
2832 reply in server. Affected file silcd/command_reply.c.
2834 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2836 * If the incoming packet type is REKEY or REKEY_DONE process
2837 that packet always synchronously. Fixes yet another MAC
2838 failed error on slow (dialup) connections. Affected file
2839 lib/silcclient/client.c and silcd/server.c.
2841 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2843 * Call check_version SKE callback for initiator too. Affected
2844 file lib/silcske/silcske.c.
2846 * Implemented fix for security hole found in the SKE that was
2847 fixed in the specification few days back; the initiator's
2848 public key is now added to the HASH value computation.
2849 Added backwards support for the old way of doing it too, for
2850 old clients and old servers. Affected file is
2851 lib/silcske/silcske.c.
2853 * Enabled mutual authentication by default in SKE. If initiator
2854 is not providing mutual authentication the responder will
2855 force it. This will provide the proof of posession of the
2856 private key for responder. The affected files are
2857 lib/silcclient/protocol.c and silcd/protocol.c.
2859 * Do not cache anymore the server's public key during SKE.
2860 We do mutual authentication so the proof of posession of
2861 private key is done, and if the server is authenticated in
2862 conn auth protocol with public key we must have the public
2863 key already. Affected file silcd/protocol.c.
2865 * Added new global debug variable: silc_debug_hexdump. If
2866 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
2867 file lib/silcutil/silclog.[ch].
2869 * Fixed compilation warning due to char * -> const char *.
2870 Affected files lib/silcutil/silcnet.h, and
2871 lib/silccore/silcauth.[ch].
2873 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2875 * Fixed CMODE command when new channel key was created. If
2876 the creation failed the old key was removed. Next time giving
2877 same command would crash the server since the old key was
2878 freed already. Affected file silcd/command.c.
2880 * Fixed the silc_server_announce_get_channels to not crash
2881 on reconnect. Affected file silcd/server.c.
2883 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2885 * Added silc_log_set_debug_string function to set a regex
2886 string to match for debug output. Only the function names,
2887 or filenames matching the given debug string is actually
2888 printed. This way it is possible to filter out those debug
2889 strings that user is not interested in.
2891 Fixed a bug in silc_string_regexify.
2893 Affected files lib/silcutil/silclog.[ch], and
2894 lib/silcutil/unix/silcunixutil.c.
2896 * Changed the -d options in both server and Irssi SILC client
2897 to take the debug string as argument. Affected files
2898 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
2900 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2902 * Added silc_hash_babbleprint to create a Bubble Babble
2903 Encoded fingerprint. The encoding is developed by Antti
2904 Huima (draft-huima-babble-01.txt), and it creates human
2905 readable strings out of binary data. Affected file
2906 lib/silccrypt/silchash.[ch].
2908 * Print the babble print now in addition of fingerprint as well
2909 in Irssi SILC client. Affected files are
2910 irssi/src/fe-common/silc/module-formats.[ch],
2911 irssi/src/fe-common/silc/core/client_ops.c.
2913 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2915 * Fixed a security problem found in SKE. The initiator's
2916 public key too is now added to the HASH hash value creation
2917 which is signed by the responder to create the SIGN value.
2918 This will prevent anyone in the middle to lie to the responder
2919 about the initiator's public key. If this is done now, the
2920 man in the middle will get caught. Updated the protocol
2923 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2925 * Better installation directory handling. Configure module
2926 paths and other paths automatically to example_silc* files
2927 in doc/. A patch by toma.
2929 * Fixed compiler warning from MPI library, and from SILC RNG.
2932 * Added SILC_SERVER_PID_FILE to define the pid file for server.
2933 It can be configured with ./configure. A patch by toma.
2935 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2937 * Find correct make to use in prepare-clean. A patch by
2938 toma. Affected file prepare-clean.
2940 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
2942 * Added irssi variables use_auto_addr, auto_bind_ip,
2943 auto_bind_port and auto_public_ip.
2945 * Changed the interface for silc_client_send_key_agreement
2946 in lib/silcclient/silcapi.h
2950 irssi/src/silc/core/silc-core.c
2952 lib/silcclient/silcapi.h
2953 irssi/src/silc/core/silc-channels.c
2954 lib/silcclient/client_keyagr.c
2957 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2959 * Added silc_pkcs_public_key_compare to compare two
2960 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
2962 * Check that the client who set the founder mode on the
2963 channel is the same client that is giving the founder
2964 mode to itself. It is done by comparing the saved public
2965 key (it is saved even in the authentication is passphrase).
2966 Affected file silcd/command.c.
2968 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2970 * Do not process packet for disconnected socket connection.
2971 Affected file lib/silccore/silcpacket.c.
2973 * Process the DISCONNECT packet through scheduler in the
2974 client library. Affected file lib/silcclient/client.c.
2976 * Fixed the silc_client_packet_parse to not to increase
2977 the packet sequence number if the conn->sock and the
2978 current socket connection is not same. This can happen
2979 for example during key agreement when the conn includes
2980 multiple socket connections (listeners). Affected file
2981 lib/silcclient/client.c.
2983 * The sender of the file transfer request now provides also
2984 the pointer (listener) for the key exchange protocol. If
2985 the listener cannot be created then it sends empty key
2986 agreement and lets the receiver provide the listener.
2988 Added `local_ip' and `local_port' arguments to the
2989 silc_client_file_send. If they are provided they are used,
2990 if not then it will attempt to find local IP address, if
2991 not found or bind fails then the remote client will provide
2994 Affected files are lib/silcclient/client_ftp.c and
2995 lib/silcclient/silcapi.h.
2997 * Extended the FILE SEND command to support defining the
2998 local IP and port for key exchange listener. They are
2999 optional. Affected file irssi/src/silc/core/silc-servers.c.
3001 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3003 * Defined to WHOIS command reply the sending of fingerprint
3004 of the client's public key (if the proof of posession of the
3005 corresponding private key is verified by the server).
3006 Updated to the protocol specification.
3008 * Added support of receiving the client's public key's
3009 fingerprint in command reply in client library. Affected
3010 file is lib/silcclient/command_reply.c, and
3011 lib/silcclient/idlist.[ch].
3013 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3015 * Do not send over 128 chars long nickname to the server
3016 in NICK command. Affected file lib/silcclient/command.c.
3018 * Do not send over 256 chars long channel names to the server
3019 in JOIN command. Affected file lib/silcclient/command.c.
3021 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3023 * Assure that silc_server_close_connection cannot be called
3024 twice for same socket context. Affected file is
3027 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3029 * Send error message to application if opening file for
3030 writing during file transfer fails. Affected file is
3031 lib/silcclient/client_ftp.c.
3033 Remove all file transfer sessions for a client that we're
3034 removing from ID cache.
3036 Affected file is lib/silcclient/client_ftp.c.
3038 * Fixed silc_net_addr2bin to return correct address. Affected
3039 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3041 * Fixed file transfer session removing on signoff notify.
3042 Affected file irssi/src/silc/core/silc-servers.c.
3044 * Added the SilcClientFileError to be returned in the monitor
3045 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
3046 Affected file lib/silcclient/silcapi.h.
3048 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3050 * Fixed a crash in silc_client_ftp_free_sessions and
3051 silc_client_ftp_session_free_client. Affected file
3052 lib/silcclient/client_ftp.c.
3054 * Added `disabled' field in the SilcChannelEntry in the server
3055 to indicate if the server entry is disabled. Affected file
3056 silcd/idlist.h, silcd/command[_reply].c.
3058 * SILC server adds now /var/run/silcd.pid everytime it is
3059 started. Affected file silcd/silcd.c.
3061 * Added silc_server_packet_send_clients to send a packet to
3062 the provided table of client entries. Affected file
3063 silcd/packet_send.[ch].
3065 * Fixed a crash in client resolving in client_prvmsg.c in
3066 client library. Affected file lib/silcclient/client_prvmsg.c.
3068 * Do not actually remove the client directly from ID cache
3069 during SERVER_SIGNOFF, but invalidate it. This way we
3070 preserve the WHOWAS info for the client. Affected file
3071 silcd/server_util.c.
3073 * Fixed SERVER_SIGNOFF notify handling in the server. The
3074 server is now able to process incoming SERVER_SIGNOFF notify
3075 for a server that it doesn't even know about. It will remove
3076 the clients provided in the notify. Affected file
3077 silcd/packet_receive.c.
3079 * Check for partial packet in data queue after every packet that
3080 was found from the queue. Return and wait for more data if
3081 there is partial data in queue. Affected file is
3082 lib/silccore/silcpacket.c.
3084 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3086 * Added SilcClietFileError enum to indicate error in
3087 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
3088 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
3089 Affected files lib/silcclient/silcapi.h and
3090 lib/silcclient/client_ftp.c.
3092 * Check that newsize in silc_buffer_realloc is larger than
3093 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
3095 * Added better monitor of file transfers. It now monitors
3096 key agreement protocol during the file transfer too. Added
3097 error reporting too. Affected files
3098 irssi/src/silc/core/silc-servers.c,
3099 irssi/src/fe-common/silc/module-formats.[ch].
3101 * Wrote a help file for FILE command.
3103 * Added silc_rng_global_get_byte_fast to get not-so-secure
3104 random data as fast as possible. Random data is read from
3105 /dev/urandom if available and from the SILC RNG if not
3106 available. It is used in padding generation. Affected file
3107 lib/silccrypt/silcrng.[ch].
3109 * All packets in client library are now processed synchronously.
3110 Optimized packet processing a lot. Affected file
3111 lib/silcclient/client.c.
3113 * All server connection packets are processing synchronously
3114 now in server, to optimize packet processing. Affected file
3117 * Include files are installed now only in Toolkit distribution
3118 if make install is given. Affected files: all Makefile.am's.
3120 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3122 * Assure that silc_client_notify_by_server_resolve does not
3123 resolve the client information multiple times. If it cannot
3124 be found by the first it cannot be found at all. Affected
3125 file lib/silcclient/client_notify.c.
3127 * Fixed WHOWAS command reply calling. Affected file
3128 lib/silcclient/command_reply.c.
3130 * Removed all references to silc_idlist_get_client from the
3131 Irssi SILC client since that call is internal call used by
3132 the library. The Irssi SILC client will use now client
3133 retrieval functions found in silcapi.h.
3135 * Fixed a bug in resolving nickname info before sending
3136 private message. It used freed memory. Affected file
3137 irssi/src/silc/core/silc-servers.c.
3139 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3141 * Assure my_channels statistics cannot go negative in server.
3142 Affected files silcd/server.c, silcd/server_util.c.
3144 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3146 * Upgraded dotconf 1.0.2 to 1.0.6 in lib/dotconf.
3148 Tue Oct 23 13:51:19 EEST 2001 Pekka Riikonen <priikone@silcnet.org>

3158 * Added silc_net_localip to return local host's IP address.
3159 Affected file lib/silcutil/silcnet.[ch].
3161 * If key exchange or rekey protocol is active for a connection
3162 parse all packets syncronously since there might be packets
3163 in packet queue that we are not able to process without first
3164 processing packets before them. Affected file silcd/server,
3165 lib/silcclient/client.c.
3167 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
3168 whether library should continue processing the packet.
3169 Affected file lib/silccore/silcpacket.h.
3171 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
3172 SilcSFTPMonitorData to SFTP server to monitor various

3215 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
3216 is incomplete and is being resolved, it won't be resolved
3219 Make sure also that USERS command reply does not resolve
3220 twice information. Affected file is
3221 lib/silcclient/command_reply.c.
3223 Make sure that silc_client_get_clients_by_list does not
3224 resolve twice same information.
3226 * Check for valid client->id in the silc_server_free_client_data.
3227 Affected file silcd/server.c.
3229 * Fixed /GETKEY nick@server not to crash if the server entry
3230 is not found. Affected file lib/silcclient/command.c.
3232 * Fixed the silc_server_check_cmode_rights to check the

3238 Affected file silcd/command.c.
3240 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3242 * Call the silc_server_udpate_servers_by_server in the
3243 primary router that comes back online in the backup resuming
3244 protocol. Otherwise it routes packets wrong. Affected file
3245 silcd/server_util.[ch], silcd/server_backup.c.
3247 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3249 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
3250 lib/silcutil/silcbuffmt.[ch].
3252 * Redefined the SILC packet header to include the padding
3253 length. Affected file lib/silccore/silcpacket.[ch].
3255 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
3256 length for maximum padding up to 128 bytes). Affected
3257 file lib/silccore/silcpacket.h.
3259 * Removed all backwards support for old 0.5.x MAC thingies.
3260 The SILC packet header change makes it impossible to be
3261 backwards compatible.
3263 * Send the ENDING packet with timeout in the backup resuming
3264 protocol. This is to assure that all routers has connected
3265 to the primary router. Affected file silcd/server_backup.c.
3267 * Changed the RNG to take the first IV from random data. It
3268 used to take it from zero actually. Changed the RNG also
3269 to use /dev/urandom during session. /dev/random is used
3270 in initialization. Affected file lib/silccrypt/silcrng.[ch].
3272 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3274 * Changed the SILC packet header to have the first two bytes
3275 (the packet length) encrypted. Affected files aroung the
3276 code tree, lib/silccore/silcpacket.[ch]. Removed the
3277 SilcPacketCheckDecrypt callback. It is not needed anymore
3278 since the silc_packet_receive_process will determine now
3279 whether the packet is normal or special.
3281 * Implemented the unidirectional MAC keys. Affected files
3282 lib/silcske/silcske.c, silcd/protocol.c and
3283 lib/silcclient/protocol.c.

3287 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
3288 lib/silcclient/protocol.c.
3290 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3292 * Allow backup router to announce servers. All servers
3293 announced by backup router are added to the global list
3294 automatically. Update hte server's socket to our primary
3295 router also when backup router announces a server.
3296 Affected file silcd/packet_receive.c.
3298 * Do not update the client->router in the function
3299 silc_server_udpate_clients_by_server if the client is on
3300 global list. We might fail to find any specific server
3301 for locally connected clients and local cell clients. They
3302 should still use the `from' and not `to' as client->router.
3303 This fixes backup router resuming protocol. Affected file
3304 silcd/server_util.c.
3306 * Decrease channel statistics count only if the channel
3307 deletion worked. Affected files are silcd/server.c and
3308 silcd/server_util.c.
3310 * Added silc_server_update_servers_by_server to update origin
3311 of all server entries. Used during backup router protocol.
3312 Affected files silcd/server_util.[ch], silcd/server.c. and
3313 silcd/backup_router.c.
3315 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
3316 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
3317 silc_hmac_get_hash and silc_hmac_get_name. Affected file
3318 lib/silccrypt/silchmac.c.
3320 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3322 * Assure that router cannot reroute the same channel message
3323 to the sender. Affected file silcd/packet_receive.c.
3325 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3327 * Made better checks that the channel message is not sent
3328 to the router it came from. Affected file is
3329 silcd/packet_send.c. Fixed memory leak too.
3331 * Announce informations for incoming router connection, but
3332 only after checking if it is replaced by backup router.
3333 Affected file silcd/packet_receive.c.
3335 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3337 * Fixed the backup resuming protocol to work in multiple
3338 router environment. Affected file silcd/server_backup.c.
3340 * Route packet only to one router in the function
3341 silc_server_packet_send_to_channel. Affected file is
3342 silcd/packet_send.c.
3344 * Fixed silc_server_send_notify_dest to set the broadcast
3345 flag. Fixed the silc_server_send_notify_topic to actually
3346 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
3347 Affected file silcd/packet_send.c.
3349 * Changed the SFTP Filesystem interface. Changed the
3350 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
3351 the filesystem operation function. The SilcSFTPFilesystem
3352 is now a context that is allocated by all filesystem allocation
3353 functions and it already includes the operations structure
3354 and filesystem specific context. It is given as argument
3355 now to the silc_sftp_server_start. This made the interface
3356 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
3357 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
3359 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3361 * Changed the backup router adding and getting interfaces
3362 in the server. The router that will be replaced by the
3363 specified backup router is now sent as argument. Affected
3364 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
3367 * Added silc_net_addr2bin_ne to return the binary form of
3368 the IP address in network byte order. Affected files
3369 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
3371 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3373 * Check for existing server ID in silc_server_new_server
3374 and in silc_server_connect_to_router_final and remove the
3375 old entry if it exists. Affected file silcd/packet_receive.c,
3378 * Send the channel message always to only one router, either
3379 in upstream or downstream. Affected file is
3380 silcd/packet_send.c.
3382 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3384 * Wrote the definition of the backup resuming protocol to the
3385 protocol specification.
3387 * Removed one redundant channel key generation from normal
3388 server during joining procedure. Removed one redundant
3389 channel key sending from server to router during joining
3390 procedure. Affected file silcd/command.c.
3392 * Made minor bugfixes to the backup router resuming protocol.
3393 Affected file silcd/server_backup.c, server.c.

3398 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
3401 * Implemented the backup resuming protocol that is used to
3402 resume the primary router position in the cell after the
3403 primary router comes back online. Affected files
3404 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
3405 and silcd/server_util.[ch].
3407 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3409 * Sleep two (2) seconds after sending QUIT command to server.
3410 Affected file lib/silcclient/command.c.
3412 * Assure that if outgoing data buffer is pending do not force
3413 send any data. Affected file silcd/packet_send.c.
3415 * Assure that if outgoing data buffer is pending do not force
3416 send any data. Affected file lib/silcclient/client.c.
3418 * Implemented the backup router support when the primary router
3419 goes down. The servers and routers can now use the backup
3420 router as new primary router without loosing connectivity.
3422 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3424 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
3425 in the server to indicate disabled entry. All data read
3426 from the connection will be ignored and no data is sent
3427 for entry that is disabled. Affected files are
3428 silcd/idlist.h, silcd/server.c.
3430 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3432 * Created SFTP client and server test programs in the
3433 lib/silcsftp/tests directory.
3435 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3437 * Implemented memory filesystem (virtual filesystem) for
3438 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
3441 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3443 * Implemented the SFTP (SSH File Transfer Protocol) to the
3444 lib/silcsftp. It includes SFTP client and SFTP server
3447 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3449 * Moved lib/silccore/silcprotocol.[ch] to the
3450 lib/silcutil library.
3452 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
3453 take variable argument list pointer as argument. Affected
3454 file lib/silcutil/silcbuffmt.[ch].
3456 * Added silc_buffer_set function that is used to set data
3457 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
3458 Affected file lib/silcutil/silcbuffer.h.
3460 * Changed various routines in the core library to use the new
3461 silc_buffer_set instead of allocating new buffer only for
3464 * Added 64-bit value formatting and unformatting support to the
3465 silc_buffer_[un]format routines. Affected file is
3466 lib/silcutil/silcbuffmt.[ch].
3468 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
3469 to includes/bitmove.h.
3471 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3473 * Fixed channel user mode saving in client library. Affected
3474 file lib/silcclient/command[_reply].c.
3476 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3478 * Defined the file transfer to the SILC Protocol. Added
3479 new packet type SILC_PACKET_FTP and defined File Transfer
3480 Payload. The mandatory file transfer protocol is SFTP
3481 (SSH File Transfer Protocol). Affected file in addition
3482 of the internet draft is lib/silccore/silcpacket.h.
3484 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
3485 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
3486 is used as part of backup router protocol when the primary
3487 router of the cell is back online and wishes to resume
3488 the position as primary router.
3490 * Redefined the MAC generation keys in the protocol. The
3491 same key is not used anymore in both direction. Both
3492 direction will now use different keys for sending and
3493 receiving. This fixes a potential security flaw. This
3494 change causes incompatibilities in the protocol.
3496 * Redefined also the MAC computation from the packet.
3497 An packet sequence number is now added to the MAC
3498 computation. This prevents possible replay attacks against
3499 the protocol. This change too causes incompatibilities
3502 Added `sequence' field to the SilcPacketContext to hold
3503 the current sequence number for the packet.
3505 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3507 * Added `created' field to the SilcIDListData in the file
3508 silcd/idlist.h to indicate the time when the entry was
3511 * Added `created' field to the SilcChannelEntry too. Affected
3512 file silcd/idlist.h.
3514 * Added `creation_time' aguments to all the announcement functions
3515 in the server. If it is provided then only the entries that
3516 was created after the provided time frame are actually
3517 announced. Affected file silcd/server.[ch].
3519 * The protocol says that the Channel ID's IP address must be
3520 based on the router's IP address. Added check for this in
3521 the silc_server_new_channel when processing incoming New Channel
3522 Payload. Affected file silcd/packet_receive.c.
3524 * Print out the correct version with --version in SILC client.
3525 Affected file irssi/src/silc/core/silc-core.c.
3527 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3529 * Fixed WHOWAS command to check for completnes of the client
3530 entry always, not just when the command is coming from client.
3531 Affected file silcd/command.c.
3533 * Added new function silc_server_packet_queue_purge to purge the
3534 outgoing data queue to the network. After the function returns
3535 it is guaranteed that the outgoing packet queue is empty.
3536 Affected file silcd/packet_send.[ch].
3538 * Purge the outgoing packet queue in the rekey protocol's final
3539 callback to assure that all rekey packets go to the network
3540 before quitting the protocol. Affected file silcd/server.c.
3542 * Added silc_client_packet_queue_parse as similar function as
3543 in server to the client library. The affected file is
3544 lib/silcclient/client.c.
3546 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3548 * Splitted silcd/server.c and created silcd/server_util.[ch]
3549 for utility functions.
3551 * Added new socket flag SILC_SF_DISABLED to indicate that the
3552 connection is open but nothing can be sent to or received from
3553 the connection. Affected file lib/silcutil/silsockconn.[ch].
3554 The checking for disabled socket is checked in the low level
3555 silc_socket_write and silc_socket_read functions.
3557 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3559 * Allow only nicknames and channel names that fits into the
3560 7-bit unsigned char ASCII set. Affected file silcd/command.c.
3562 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3564 * When processing JOIN command reply in server check that if
3565 the channel exists in our global list we'll move it the local
3566 list. Affected file silcd/command_reply.c.
3568 * Fixed the check whether client is joined on the channel already
3569 in JOIN command. Affected file lib/silcclient/command.c.
3571 * Fixed the JOIN command reply to check whether the channel
3572 already exists. Affected file lib/silcclient/command_reply.c.
3574 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3576 * Added silc_ske_status_string to map the SKE error numbers
3577 to readable strings. The affected files are
3578 lib/silcske/silcske[_status].[ch].
3580 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3582 * Do not show the private channels on the WHOIS channel list
3583 as it is not allowed by the protocol. The affected file is
3586 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3588 * Assure that the packet length digged from the actual packet
3589 is something sensible in the silc_packet_decrypt_rest_special
3590 in lib/silccrypt/silcpacket.c.
3592 * Free and NULL the allocated pointer in silc_hmac_alloc if
3593 the HMAC allocation fails. The affected file is
3594 lib/silccrypt/silchmac.c.
3596 * Print the selected security properties to the log files in
3597 the server. Affected file silcd/protocol.c.
3599 * Add SKE's reference counter even if calling the completion
3600 callback manually. Otherwise it goes negative, although it
3601 does not cause any problems. The affected file is
3602 lib/silcske/silcske.c.
3604 * Remove the client entry with short timeout after giving the
3605 KILL command. Affected file lib/silcclient/command.c.
3607 * Fixed to send error reply in WHOIS and IDENTIFY commands in
3608 case all found clients are already disconnected (WHOWAS would
3609 found them) in the server. Affected file silcd/command.c.
3611 * Update the last_receive (time of last data received) to be
3612 updated only when received private or channel message so that
3613 the idle time showed in WHOIS makes more sense.
3615 * Added boolean field `valid' in to the SilcClientEntry in the
3616 client library to indicate whether the entry is valid or not.
3617 This fixes the nickname change bug on channel when changing
3618 the nickname to be same than the old (like nick to Nick) the
3619 nickname formatter doesn't set the new nick anymore to Nick@host.
3620 Affected file lib/silcclient/idlist.[ch].
3622 * Now actually fixed the nickname changing on disconnection.
3623 Added new function silc_change_nick to the Irssi SILC Client.
3624 Affected file irssi/src/silc/core/client_ops.c,
3625 irssi/src/silc/core/silc-nicklist.[ch].
3627 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3629 * Check that the public key exists in the GETKEY command before
3630 trying to encode it. Affected file silcd/command.c.
3632 * Print some notifications on received public keys with GETKEY
3633 command in the Irssi SILC Client. Affected files are
3634 irssi/src/fe-common/silc/module-formats.[ch],
3635 irssi/src/silc/core/client_ops.c.
3637 * Use IDENTIFY command to resolve the server information in the
3638 GETKEY command instead of INFO command. Affected file
3639 lib/silcclient/command.c.
3641 * All command reply functions in the client library now calls
3642 the pending command reply callbacks even if an error has
3643 occurred. The server has done this a long time and now it was
3644 time to move the client library to this as well. Now all
3645 errors can be delivered back to the pending command reply
3646 callbacks if necessary. Affected files are
3647 lib/silcclient/command[_reply].[ch].
3649 * Change the nickname on disconnection back to the username
3650 because in reconnect the server will enforce it to it anyway.
3651 Affected file irssi/src/silc/core/silc-servers.c.
3653 * Fixed a config file parsing bug in the Irssi SILC client.
3654 Affected file irssi/src/silc/core/clientconfig.c.
3656 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3658 * When printing the channel mode on JOIN, verify that the
3659 channel key and channel's HMAC are valid. Affected file
3660 irssi/src/silc/core/client_ops.c.
3662 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3664 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
3665 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
3666 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
3668 * Removed channel key rekey task deleting from the function
3669 silc_server_save_channel_key. Affected file silcd/server.c.
3670 Added explicit timeout task context instead that is used to
3671 delete the task if we are registering a new task before the
3672 new task has elapsed.
3674 * When channel key rekey occurs the client library now saves
3675 the old channel key for a short period of time (10 seconds) and
3676 is able to use it in case some is still sending channel
3677 messages encrypted with the old key after the rekey. Affected
3678 file lib/silcclient/[idlist.h|client_channel.c].
3680 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3682 * Added check to the silc_server_new_id_real to not accept
3683 new ID if it is the sender's own ID. Affected file is
3684 silcd/packet_receive.c.
3686 * Assure that we do not announce ourself or the one we've
3687 sending our announcements when we're router and are announcing
3688 servers to our primary router. Affected file silcd/server.c.
3690 * Fixed silc_server_command_identify_check_client to assemble
3691 correct WHOIS packet. It send corrupted WHOIS packet and
3692 caused problem with router to router connections. Affected
3693 file silcd/command.c.
3695 Fixed also silc_server_command_whois_check the same way
3696 as for the IDENTIFY command.
3698 * Added new SilcIDListStatus to the server in the SilcIDListData
3699 structure. The status now includes the current status of
3700 the entry (like registered, resolved etc.). Affected file
3701 silcd/idlist.[ch]. Defined a bunch of different status types
3702 as well. This replaced the old boolean registered field as well.
3704 Added resolve_cmd_ident field to the SilcClientEntry structure
3705 too so that if the entry is for example being resolved so
3706 another command may attach to the same pending command reply
3707 without requiring to resolve the same entry again. This concept
3708 should optimize the WHOIS and the IDENTIFY resolving under
3709 heavy load by taking away unnecessary resolving for entries
3710 that are being resolved already.
3712 Added support for adding multiple pending commands for one
3713 command idenfier. Affected file silcd/command[_reply].[ch].
3715 * Fixed WHOIS and IDENTIFY save to remove the cache entry
3716 before deleting the data. Otherwise the hash table will have
3717 freed data in comparison functions. Affected file is
3718 silcd/command_reply.c.
3720 * Fixed silc_idlist_replace_client_id to add the new entry to
3721 the cache with NULL nickname. Otherwise there will be invalid
3722 memory as the nickname after the nickname is freed. Affected
3723 file silcd/packet_receive.c.
3725 * Fixed the silc_idlist_get_clients_by_hash. The entries was
3726 saved into wrong slots because the previous number of entries
3727 was not taken into account. Affected file silcd/idlist.c.
3728 Fixed same thing in silc_idlist_get_clients_by_nickname too.
3730 * If we are router and we receive JOIN notify to a channel that
3731 does not have any users then notified client is marked as the
3732 channel founder, as it is it. The affected file is
3733 silcd/packet_receive.c
3735 * Added to the extended hash table API's table_del_*ext functions
3736 the destructor as argument too, so that the caller can decide
3737 which destructor to use or whether to use destructor at all.
3738 Affected file lib/silcutil/silchashtable.[ch].
3740 * Fixed ID Cache purging. It actually deleted the entries from
3741 the hash table after the data was freed. The hash table ended
3742 up comparing freed memory. The affected file is
3743 lib/silccore/silcidcache.c.
3745 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3747 * Fixed Irssi SILC client's KILL command's HELP syntax.
3749 * The USERS command now resolves the detailed user information
3750 if the userinfo field is missing. Affected file is
3751 lib/silcclient/command_reply.c.
3753 * Do not print error in silc_file_read if the read file does
3754 not exist. Just silently return NULL. Affected file is
3755 lib/silcutil/silcutil.c.
3757 * Fixed the silc_log_output to not wine about NULL filename
3758 and to not create some bogus " " filename. Affected file is
3759 lib/silcutil/silclog.c.
3761 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3763 * Fixed various printing bugs on the user interface in the
3764 Irssi SILC Client. Minor changes that were forgotten from
3767 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3769 * Fixed the configure.in.pre and the compilation and distribution
3770 environment to support the new autoconf 2.52. That version is
3771 now required to compile the CVS trunk.
3773 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3775 * Renamed function silc_parse_nickname to silc_parse_userfqdn
3776 to generally parse user@fqdn format strings. Affected file
3777 lib/silcutil/silcutil.c.
3779 * Added nickname_format and nickname_force_format fields to the
3780 SilcClientParams structure. The first one defines the format
3781 for the nicknames that the library will enforce if the receives
3782 multiple same nicknames. The second one is boolean value and
3783 can be used to force the library to always enforce the format
3784 to the nicknames regardles whether there are multiple nicknames
3785 or not. This configurable formatting was employed to flexibly
3786 support accessing multiple nicknames from the user interface.
3787 The userinterface can now set the nicknames to what ever format
3788 they prefer. Affected file lib/silcclient/silcapi.h.
3790 Added function silc_client_nickname_format to the file
3791 lib/silcclient/idlist.c. It performs the nickname formatting.
3793 Added new field `hostname´ to the SilcClientEntry context.
3794 It holds the hostname of the client. Affected file is
3795 lib/silcclient/idlist.h.
3797 * Irssi SILC Client sets the nicknames in nick@hostn format.
3798 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
3799 irssi/src/silc/core/silc-core.c.
3801 The WHOIS printing now also shows both the real nickname and
3802 the formatted nickname so that user knows how to access the
3803 user if there are multiple same nicknames cached. Affected
3804 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
3805 printing formatting too to take the hostname now as a separate
3806 argument. The Affected file is
3807 irssi/src/fe-common/silc/modules-formats.[ch].
3809 * Changed the silc_client_get_clients_local to accept the formatted
3810 nickname as argument. It accepts the real nickname too but the
3811 formatted nickname can be used to find the true entry from
3812 multiple entries. Affected file lib/silcclient/silcapi.h and
3813 lib/silcclient/idlist.c.
3815 * Added nickname_format_parse field to the SilcClientParams.
3816 It is a callback function provided by the application to parse
3817 the nickname out of the formatted nickname string. The library
3818 calls it to get the nickname from the formatted string. Since
3819 the application generally knows better the format of the nickname
3820 string it parses it instead of the library, even though library
3821 encodes the formatted string. If the callback function is not
3822 provided then the library will use the string as is. The
3823 affected file is lib/silcclient/silcapi.h.
3825 * All the nickname strings passed to the client library in
3826 commands are now expected to be formatted nickname strings.
3827 If the command does not support the formatted nickname string
3828 it will assume that the sent string is the actual nickname.
3829 Affected file lib/silcclient/command.c.
3831 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3833 * Added public key authentication support to OPER and SILCOPER
3834 commands in the client library. Affected file is
3835 lib/silcclient/command.c.
3837 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3839 * Changed the get_auth_methdod client operation to be asynchronous.
3840 It can be async if the application resolves the authentication
3841 method from the server during the negotiation. Added new
3842 SilcGetAuthMeth completion callback that the application will
3843 call after resolving the authentication method.
3845 Added function silc_client_request_authentication_method that
3846 the application can use to resolve the authentication method
3847 from the server. Added also SilcConnectionAuthRequest callback
3848 that the library will call after the server has replied. The
3849 application can call this function if it does not know the
3850 current authentication method.
3852 Affected files are lib/silcclient/client.c and
3853 lib/silcclient/silcapi.h.
3855 * The Irssi SILC client now automatically resolves the authentication
3856 method incase any configuration information is not present (and
3857 currently there never is). The affected file is
3858 irssi/src/silc/core/client_ops.c.
3860 * Fixed public key authentication from the client library.
3861 Affected file lib/silcclient/protocol.c. Changed also the
3862 protocol specification about the public key authentication in
3863 the connection authentication protocol. The actual data to be
3864 signed is now computed with a hash function before signing.
3866 * Fixed the public key authentication from the server as well.
3867 Affected file silcd/protocol.c.
3869 * Removed the mlock()'s from the memory allocation routines.
3870 Affected file lib/silcutil/silcmemory.c. The ./configure does
3871 not check anymore for the mlock(). Affected file is
3874 * Fixed USERS command in server to allow the execution of the
3875 command for private and secret channels if the client sending
3876 the command is on the channel. Affected file silcd/command.c.
3878 * Fixed silc_client_get_clients_local to return the clients
3879 count correctly. It could return wrong value. Affected file
3880 lib/silcclient/idlist.c.
3882 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3884 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
3885 types. The assembler optimizations seemed not to like 64-bit
3886 data types. The assmebler optimizations thus are now enabled
3887 also for BSD systems as opposed to only enable them for Linux.
3889 * Do not check for threads at all on BSD systems. Affected
3890 file configure.in.pre.
3892 * Removed -n and -h options from the Irssi SILC Client since
3893 they are not used in silc.
3895 * Fixed the prime generation to assure that the first digit
3896 of the generated random number is not zero since our conversion
3897 routines does not like number strings that starts with zero
3898 digit. If zero digit is seen the random number is regenerated.
3899 This caused some corrupted RSA keys when the zero first digit
3900 was met. Affected file lib/silcmath/silcprimegen.c.
3902 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3904 * Fixed WIN32 configuration in the ./configure script.
3905 Fixed to include xti.h on environments that has it.
3906 Patches by Carsten Ilchmann and andrew.
3908 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3910 * Changed the silc_id_create_client_id to be collision
3911 resistant. It is now assured that there cannot be created
3912 two same client ID's. I suspect that some weird bugs in
3913 the server were actually caused by duplicate Client IDs.
3914 Affected file silcd/serverid.[ch]. A router receiving
3915 new ID now also assures and informs the sending server
3916 if the ID caused collision.
3918 * Changed the silc_id_create_channel_id to also assure that
3919 there are no collisions.
3921 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3923 * Statement about ignoring the Mutual Authentication flag when
3924 performing rekey with PFS was a bit misleading. It is ignored
3925 if it was set in the initial negotiation, it cannot be even
3926 set in the rekey. Fixed in the ke-auth draft. Started the
3927 new versions of the protocol drafts in the doc/.
3929 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3931 * Fixed a bug in silc_client_command_identify_save when saving
3932 new channel information. The channel name was no duplicated
3933 and caused crash on exit. Affected file is
3934 lib/silcclient/command_reply.c.
3936 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3938 * Fixed the getkey command handling in the server. Send just
3939 empty OK reply to the sender if the key could not be fetched
3940 (but everything else was ok, like the key just was not available).
3941 Changed the public key parameter to optional in the protocol
3942 specs so that empty OK reply can be sent. Affected file
3945 Added a message to Irssi SILC client to tell to user if the
3946 server did not return a public key.
3948 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3950 * Fixed a channel key regeneration bug. It registered new
3951 timeout tasks exponentially until all system resources were
3952 used. Affected file silcd/server.c.
3954 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3956 * Added the SILC Document generator to the scripts/silcdoc.
3957 It can be used to generate the Toolkit Reference Manual out
3958 of the source tree. Internally it will also use the RoboDoc
3959 generator now imported in util/robodoc.
3961 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3963 * Added couple of return's in rekey protocol if error orccurred
3964 during the protocol. The execution must be terminated.
3965 Affected file silcd/protocol.c. Also, terminate the protocol
3966 always with timeout.
3968 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3970 * The client's Client ID was created initally from the wrong
3971 nickname (it could have been in format nick@host) in the
3972 silc_server_new_client. Affected file silcd/packet_receive.c
3974 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3976 * Added some SILC_LOG_ERROR's to various error conditions
3977 if client could not be added to ID cache. Affected files
3978 silcd/packet_receive.c and silcd/server.c.
3980 * When client's sock->user_data is freed, NULL also the
3981 client->router and client->connection pointers. Added check
3982 for these pointers being NULL to various places around the
3983 code. Affected file silcd/server.c.
3985 * Added client->data.registered == TRUE checks to various
3986 places around the code to assure that unregistered client's
3987 are not handled when it is not allowed. Affected file
3990 * Added `bool registered' fields to all
3991 silc_idlist_[server|client]_get_* routines to indicate whether
3992 the fetched client needs to be registered or not. Affected
3993 file silcd/idlist.[ch].
3995 * Add your own entry as registered to the ID cache in the
3996 server. Affected file server.c.
3998 * Fixed a bug in silc_server_new_server. The SilcServer was
3999 set as the new server's context instead of SilcServerEntry.
4000 This naturally caused some weird bugs.
4002 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4004 * Do not delete the channel rekey task when adding it
4005 for in silc_server_create_channel_key.
4007 * Changed the silc_server_create_channel_key to return
4008 TRUE or FALSE to indicate the success of the channel key
4011 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4013 * Fixed MSVC++ project files and added missing files to
4014 Makefiles under win32/.
4016 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4018 * Do not add TCP_NODELAY flag if the operating system
4019 does not have it defined. Affected files are
4020 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
4022 * Fixed buffer overflow from Irssi SILC Client. Affected
4023 file irssi/src/fe-common/core/themes.c.
4025 * Fixed double free in client library in the file
4026 lib/silcclient/client.c when disconnecting from server.
4028 * Applied double free patch from cras to Irssi SILC client.
4029 Affected files irssi/src/core/[modules/expandos].c
4031 * Fixed the disconnection handling to Irssi SILC Client.
4032 The application must call silc_client_close_connection
4033 in ops->connect client operation in case of failure of
4034 the connection. Affected file is
4035 irssi/src/silc/core/client_ops.c.
4037 * Do not set sock->protocol to NULL in the function
4038 silc_client_close_connection after executing the protocol's
4039 final callback since the sock might not be valid anymore.
4040 Affected file lib/silcclient/client.c.
4042 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4044 * Do not enable SILC_THREADS if the linking with libpthread
4045 did not happen. Affected file configure.in.pre.
4047 * Added notion to protocol specification that server must
4048 verify the sent authentication payload with CMODE when
4049 setting the channel founder key. Implemented it to the
4050 server. Affected file silcd/command.c.
4052 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4054 * Added _EXTRA_DIST SILC distribution variable to the
4055 distributions file. It is used to conditionally add extra
4056 files or directories to the specific distribution. Affected
4057 files ./prepare, Makefile.am.pre and distributions.
4059 Removed the `_' from the start of the distribution names.
4062 * Added README.WIN32 for instructions to compile the Toolkit
4065 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4067 * Fixed a double free in disconnection in the server. Affected
4068 file is silcd/server.c.
4070 * Fixed the lib/silcske/groups.c to work now also with GMP
4071 MP library. The string conversion did not work when using
4072 specific base and the base is indicated in the string as well.
4074 * Created win32/ directory which now includes MSVC++ specific
4075 stuff so that toolkit (DLLs) may be compiled with MSVC++.
4076 It will appear only in the toolkit distribution
4078 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4080 * Changed the key material distribution function in case when
4081 the hash output is too short. The data is now concatenated
4082 a bit differently than it used to. Made the change to the
4083 SKE protocol specification.
4085 * Added better GMP detection to configure.in.pre. A patch
4088 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4090 * Fixed a minor bug in SKE that might cause some problem on
4091 some platforms. Affected file lib/silcske/silcske.c.
4093 * Added the cookie checking for initiator in the SKE. It checks
4094 that the responder returns the sent cookie unmodified. The
4095 affected file is lib/silcske/silcske.c. Added new SKE
4096 error type INVALID_COOKIE that can be sent during the
4097 negotiation. Fixed some memory leaks as well.
4099 * Added the "invalid cookie" error message to Irssi SILC client's
4102 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4104 * Added `task_max' field to the SilcClientParams to indicate
4105 the maximum tasks the scheduler can handle. If set to zero,
4106 default values are used. Affected file lib/silcclient/silcapi.h.
4108 * Fixed memory leaks in silc_client_close_connection. Affected
4109 file lib/silcclient/client.c.
4111 * Added silc_client_del_client_entry to client library to free
4112 all memory of given client entry. Affected file is
4113 lib/silcclient/idlist.[ch].
4115 * Added new functions silc_client_del_channel and
4116 silc_client_del_server to delete channel and server entries.
4117 Affected file lib/silcclient/[silcapi.h/idlist.c].
4119 * Removed silc_client_del_client_by_id from silcapi.h.
4121 * Fixed the INFO command to return the server's own info
4122 correctly when querying by Server ID. Affected file is
4125 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4127 * Removed the non-blocking settings in WIN32 code in the
4128 silc_sock_[read/write] and added SleepEx instead. Affected
4129 file lib/silcutil/win32/silcwin32sockconn.c. The availability
4130 of input data is now checked with FIONREAD and ioctlsocket.
4132 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4134 * Call silc_schedule_task_del_by_context in the
4135 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
4136 Affected file lib/silccore/silcprotocol.c.
4138 * Call silc_protocol_cancel for active protocols in the
4139 silc_server_close_connection if the funtion
4140 silc_server_free_sock_user_data has not been called.
4141 Affected file silcd/server.c.
4143 * Generic tasks cannot be deleted using the del_by_fd
4144 task deleting function since generic tasks does not match
4145 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
4147 * Added a notion to SILCOPER help file that the SILCOPER works
4148 only on router server, not on normal server.
4150 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4152 * Added for WIN32 support for the new scheduler as well.
4153 Affected file lib/silcutil/win32/silcwin32schedule.c.
4155 * Fixed the SHA1 implementation to work on various platforms.
4157 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4159 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
4160 API. It is part of the scheduler now. Everything else is
4161 as previously but some functions has changed their names.
4162 Checkout the lib/silcutil/silcschedule.h for the interface.
4163 Updated all applications to use the new interface. Affected
4164 files are lib/silcutil/silcschedule.[ch].
4166 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4168 * Found a bug in the SKE implementation. The HASH value,
4169 specified by the protocol, was not computed correctly. The
4170 public key of the responder was not added to the computation
4171 even though it is mandatory. Affected file lib/silcske/silcske.c.
4172 This unfortunately causes incompatibilities with older
4173 clients and servers.
4175 * Added WIN32 specific network init and uninit functions:
4176 silc_net_win32_init and silc_net_win32_uninit to init and uninit
4177 the Winsock2. Affected file lib/silcutil/silcnet.h and
4178 lib/silcutil/win32/silcwin32net.c.
4180 * Set the socket always to nonblocking mode on WIN32 after
4181 reading data or writing data. Affected file is
4182 lib/silcutil/win32/silcwin32sockconn.c.
4184 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4186 * Fixed various compilation problems under WIN32. Affected
4187 files lib/silcutil/win32/silcwin32thread.c and
4188 lib/silcutil/win32/silcwin32schedule.c.
4190 * Removed all _internal.h #includes from public header
4191 files. Internal headers must never be included from
4194 Removed also the lib/silcske/payload_internal.h file.
4196 * All include files that may be needed (public and some others
4197 included by the public headers) by application developers are
4198 now copied to the ./includes directory. It does not copy any
4199 internal headers. Affected file Makefile.defines.pre and all
4200 Makefile.am's under lib/ and subdirs.
4202 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4204 * Do not change the ~/.silc directory's permissions automatically.
4205 Affected file irssi/src/silc/core/clientutil.c.
4207 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4209 * Do not cancel the protocol in silc_server_close_connection
4210 it might cause recursion. Now cancelled in the function
4211 silc_server_free_sock_user_data. Affected file silcd/server.c.
4213 * Fixed the silc_server_remove_clients_by_server to regenerate
4214 the channel keys correctly finally. Added also new function
4215 silc_server_remove_clients_channels to actually do it.
4216 Affected file silcd/server.c.
4218 * Fixed the silc_server_new_channel to not crash by giving
4219 wrong router to the new channel. Affected file is
4220 silcd/packet_receive.c.
4222 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4224 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
4225 which is given as argument to the silc_client_alloc now.
4226 It can be used to configure the client and set various parameters
4227 that affect the function of the client.
4229 * The USERS command in server did not check whether the channel
4230 is private or secret. Affected file silcd/command.c.
4232 * Added new argument to the USERS command in protocol specification.
4233 The USERS command now can take the channel name as argument
4234 as well. Added support for this in client and server and
4235 updated the protocol specs.
4237 * Completed the GETKEY command in client. It can be now used
4238 to fetch also servers public key not only some clients.
4239 Affected files lib/silcclient/command[_reply].c.
4241 * Added silc_client_get_server to return server entry by the
4242 server name. Affected files lib/silcclient/silcapi.h and
4245 * Redefined the IDENTIFY command in protocol specification to be
4246 more generic. It now can be used to query information about
4247 any entity in the SILC Network, including clients, servers and
4248 channels. The query may be based either the entity's name
4249 or the ID. Added support for this in both client and server.
4251 Affected files silcd/command.c and lib/silcclient/command.c
4252 and command_reply.c.
4254 * Optimized the WHOIS and WHOWAS commands in the server. Removed
4255 the _from_client and _from_server functions. Affected file
4258 * Added silc_client_get_channel_by_id_resolve to the file
4259 lib/silcclient/silcapi.h to resolve channel information by
4260 its ID. Added also silc_client_get_channel_by_id that
4261 does not resolve it from the server.
4263 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4265 * Added SilcServerEntry context into the client library
4266 to represent one server. The INFO command now allocates
4267 these to save the resolved server info. For now on the
4268 client library will also keep information about servers,
4269 connected and resolved with INFO.
4271 The INFO command now allocates the SilcServerEntry context
4272 and saves the server info there. The COMMAND_REPLY in
4273 the INFO now returns the parameters to application in
4274 same order as defined in the protocol specification.
4276 The entries are cached in the client->server_cache.
4278 * The INFO command is now issued after received the Client ID
4279 from the server. Affected file lib/silcclient/client.c.
4281 * The CMODE_CHANGE notify may now return also an SilcServerEntry
4282 to the application as the mode changer might be server.
4283 It is guaranteed that NULL is not returned anymore to the
4284 application. Affected file lib/silcclient/client_notify.c.
4286 The ID Type is now also passed to the application so that
4287 it can check whether the returned entry is SilcClientEntry
4290 Added new function silc_client_get_server_by_id to return
4291 the server entry by ID. Affected files are the
4292 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
4294 * Do not create the channel in the Irssi SILC Client when issuing
4295 the JOIN command but when received the sucessful JOIN command
4296 reply. Otherwise the channel might get created even though we
4297 could not join it. The Affected file is
4298 irssi/src/silc/core/[silc-channels.c/client_ops.c].
4300 * Fixed a channel joining bug in router. The router must also
4301 check the channel modes, invite and ban lists etc. when serving
4302 the JOIN command sent by normal server. Affected file is
4303 silcd/command.c. The router now resolves the client's
4304 information from the server who sent the JOIN command if it
4305 does not know it, and processes the JOIN command only after
4308 * Changed the SilcCommandCb to take new argument; void *context2.
4309 Affected file lib/silccore/silccommand.h
4311 The second argument in the command callbacks in the server now
4312 includes the SilcServerCommandReplyContext if the command was
4313 called as pending command callback from the command reply.
4314 Otherwise it is NULL. When called as pending the status of the
4315 command reply will be checked and if it was erronous the
4316 error will be sent to the original sender of the command.
4317 This way the client always receives the error messages even
4318 though the server was actually the one who received the error
4319 when it resent the command to router, for example. Affected
4320 files silcd/command[_reply].[ch].
4322 * Fixed sending WHOWAS command's error message to client if
4323 the requested client could not be found. It was missing.
4326 * Changed the CMODE and CUMODE commands reply arguments in the
4327 protocol specification. The Channel ID is now sent in both
4328 of the commands to identify the channel. Implemented this
4329 new feature to the client and server. Affected files
4330 lib/silcclient/command_reply.c and silcd/command.c.
4332 * Made better checks for invite and ban lists in the JOIN
4333 command in server. Affected file silcd/command.c.
4335 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4337 * The server now performs the incoming host IP/DNS lookup
4338 using the silc_socket_host_lookup and thus does not block
4339 the server anymore. Affected file silcd/server.c.
4341 * Completed the multi-thread support for SILC Scheduler in
4342 the lib/silcutil/silcschedule.c.
4344 * Fixed the configure.in.pre to detect the pthread correctly
4347 * Fixed a deadlock in silc_task_queue_wakeup in the file
4348 lib/silcutil/silctask.c.
4350 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4352 * Added new function silc_schedule_wakeup that is used in
4353 multi-threaded environment to wakeup the main thread's
4354 schduler. It needs to be used when a thread adds a new task
4355 or removes a task from task queues. After waking up, the
4356 scheduler will detect the task queue changes. If threads
4357 support is not compiled in this function has no effect.
4358 Implemented the wakeup mechanism to both Unix and WIN32
4359 systems. Affected files are lib/silcutil/silcschedule.[ch],
4360 lib/silcutil/unix/silcunixschedule.c and the
4361 lib/silcutil/win32/silcwin32schedule.c.
4363 * Added new function silc_task_queue_wakeup to wakeup the
4364 scheduler by the specified task queue. Affected file
4365 lib/silcutil/silctask.[ch].
4367 * The silc_socket_host_lookup_start now wakes up the scheduler
4368 after adding the timeout task. Affected file is
4369 lib/silcutil/silcsockconn.c.
4371 * The silc_socket_host_lookup is synchronous now if the threads
4372 support is not compiled in. However, the callback is still
4373 called asyncronously through the scheduler, anyway. Affected
4374 file lib/silcutil/silcsockconn.c.
4376 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4378 * Added new function silc_socket_host_lookup to perform
4379 asynchronous IP and FQDN lookups for the socket connection.
4380 Affected files lib/silcutil/silcsockconn.[ch].
4382 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4384 * Added SILC_MUTEX_DEFINE to define the mutex on environments
4385 that may or may not compile the mutex support in.
4387 Changed the silc_mutex_alloc interface. It allocates the
4388 mutex now to the sent pointer and returns TRUE or FALSE.
4390 Affected file lib/silcutil/silcmutex.h.
4392 * Wrote the SILC Task Queue interface to support multi-threads.
4393 Affected file lib/silcutil/silctask.[ch].
4395 * Wrote the SILC Scheduler to support multi-threads. Affected
4396 file lib/silcutil/silcschedule.c.
4398 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4400 * Implemented the SILC Mutex API and SILC Thread API for WIN32
4401 in lib/silcutil/win32/.
4403 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4405 * Defined SILC Mutex API and SILC Thread API and implemented
4406 them for Unix. Affected files are
4407 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
4408 lib/silcutil/unix/silcunixmutex.c and
4409 lib/silcutil/unix/silcunixthread.c.
4411 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4413 * Fixed the silc_server_remove_clients_by_server's channel
4414 key re-generation. The hash table handling was incorrect
4415 and would not work with many channels. Affected file is
4418 * Fixed some memory leaks around the server code.
4420 * Rewrote the silc_server_get_users_on_channel to support IPv6
4421 based Client ID's. Affected file silcd/server.c.
4423 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
4424 specification. However, a separate document must be written
4425 to define the detailed signing procedure and the payload
4426 associated with the flag. Defined the flag to the
4427 lib/silccore/silcchannel.h as well.
4429 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4431 * Changed the dynamic tables to static size tables in the
4432 lib/silccrypt/silchmac.c.
4434 * Removed GCC dependencies from the code. A patch by cras.
4436 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4438 * Do not show the error "Error receiving packet bla bla"
4439 in server if it really was not an error (-2 means that reading
4440 is pending). Affected file silcd/server.c.
4442 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4444 * Fixed a possible crash in silc_server_remove_clients_by_server
4445 in silcd/server.c. Fixed there also some memory leaks.
4447 * Fixed the silc_idlist_replace_client_id. It could replace
4448 wrong key in the hash table. Affected file silcd/idlist.c.
4450 * Do not check whether there are global users on the channel
4451 if the channel->global_users is FALSE. Affected functions
4452 silc_server_remove_from_one_channel and
4453 silc_server_remove_from_channels in silcd/server.c. Also,
4454 do not check if the removed client is local as we can be
4455 sure that global client was not removed from the channel
4456 and checking for global users is not needed.
4458 * The silc_server_remove_clients_by_server now re-generates
4459 the channel keys correctly for those channels that had
4460 clients removed from them. Affected file silcd/server.c.
4462 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4464 * Found the reason of random crashes in the server. We weren't
4465 ignoring the SIGPIPE signal (which can be sent in write())
4466 and it crashed the server. Affected file silcd/silcd.c.
4468 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4470 * Assure that sock->user_data is not NULL in the function
4471 silc_server_packet_send in silcd/packet_send.c.
4473 * Disconnect the remote connection if it could not be added
4474 to any ID lists in the server. The affected file is
4477 * Check in silc_server_packet_send[_real/dest] that the
4478 socket is not disconnecting and ignore the data if it is.
4479 Affected file silcd/packet_send.c.
4481 * Define inline to __inline on native WIN32 compilation.
4482 Affected file includes/silcwin32.h.
4484 * Added some explicit type casts for inline code since MSVC
4485 require them. Affected files lib/silcutil/silcbuffer.h,
4486 lib/trq/silcdlist.h and lib/trq/silclist.h.
4488 * Print warning in log files from now on if the packet
4489 decryption fails. Affected file silcd/server.c.
4491 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4493 * Changed the `say' client operation's interface to accept
4494 new `type' argument to indicate the type of the message sent
4495 by the library. The application may filter the library's
4496 messages according the type. The affected file is the
4497 lib/silcclient/silcapi.h.
4499 * Added two new functions to lib/silcclient/silcapi.h:
4500 silc_client_del_client and silc_client_del_client_by_id.
4501 Affected file lib/silcclient/idlist.c.
4503 * Moved the clientincludes.h from includes/ to silc/ and
4504 serverincludes.h from includes/ to silcd/.
4506 * The modes for the CMODE and CUMODE are now passed as
4507 uint32 for application with COMMAND_REPLY. The affected
4508 file is lib/silcclient/command_reply.c.
4510 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4512 * /WHOIS without arguments shows client's own information.
4513 Affected file lib/silcclient/command.c.
4515 * Changed PING to not accept any arguments. The specs
4516 says that client can ping only the connected server so
4517 requiring an argument is not needed. Affected file is
4518 lib/silcclient/command.c.
4520 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4522 * Fixed a fatal bug in private message sending and reception
4523 encryption and decryption when using private message keys.
4524 The implementation was incorrect and did not follow the
4525 specification. It causd that some of the message were
4526 lost since it did not use the sending and receiving keys
4527 as the protocol suggests. This has been fixed and will cause
4528 incompatibilities with older clients when sending private
4529 message encrypted with private message keys. Affected files
4530 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
4531 and various other in Irssi SILC Client.
4533 Added `responder' boolean argument to the functions
4534 silc_client_add_private_message_key[_ske] to indicate when
4535 the key is added as responder or initiator of the key
4538 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4540 * Removed the silc_ske_check_version function and created
4541 a SilcSKECheckVersion callback. Added also a function
4542 silc_ske_set_callbacks that is now used to set all SKE
4543 callbacks. The callback functions are not given to
4544 the SKE functions anymore, but this function is used to
4547 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
4549 * Added `silc_version' argument to the silc_client_alloc
4550 to define the version of the application for the library.
4551 The library will use the version string to compare it
4552 against the remote host's (usually a server) version
4553 string. Affected file lib/silcclient/silcapi.h
4555 * Added the KE protocol context to Key Agreement context
4556 in client library so that we can abort the SKE if it
4557 is in process when we get timeout. Affected file is
4558 lib/silcclient/client_keyagr.c.
4560 * Do not resolve the client ID forever if it returns in the
4561 first time that such client does not exist. This was done
4562 for example with private message. Affected file is
4563 lib/silcclient/client_prvmsg.c.
4565 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4567 * Do not add regex.h for WIN32. The affected file
4568 includes/silcincludes.h.
4570 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
4571 not work yet 100%. It generates the DLL's automatically
4572 when compiling with --with-win32 under cygwin.
4574 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4576 * lib/contrib/regex.c is not compiled on WIN32.
4578 * Added silc_net_get_socket_opt function to the
4579 lib/silcutil/silcnet.h.
4581 * Added includes/silcwin32.h for WIN32 specific includes
4584 * Do not use ptime structure or any of the posix process
4585 functions on WIN32 in lib/silccrypt/silrng.c.
4587 * Added silc_gettimeofday to provide generic function
4588 for struct timeval on all platforms. Added the function
4589 to lib/silcutil/silcutil.h.
4591 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4593 * Moved the lib/silccore/silcsockconn.[ch] to the utility
4594 library as they clearly belong there. As a plus side we
4595 can make the actual socket connection routines platform
4598 Added also new generic function silc_socket_read and
4599 silc_socket_write (that used to be silc_packet_[read/write].
4600 The implementation of these are platform specific.
4602 * Added WIN32 specific routines of silc_socket_[read/write]
4603 to lib/silcutil/win32/silcwin32sockconn.c.
4605 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4607 * Added preliminary support for native WIN32 compilation under
4608 cygwin (using the -mno-cygwin option for GCC) to the
4609 ./configure.in.pre. The --with-win32 now prepares the
4610 compilation for native WIN32.
4612 * Rewrote the SILC Scheduler interface in the file
4613 lib/silcutil/silcschedule.h. The scheduler is now context
4614 based and does not have anymore any global static scheduler.
4615 Moved the Unix scheduler to the lib/silcutil/unix/ directory
4616 and created lib/silcutil/win32 directory for WIN32 based
4619 * Added Unix specific network routines to the
4620 lib/silcutil/unix/silcunixnet.c and the old
4621 lib/silcutil/silcnet.c includes now only generic routines.
4623 Added WIN32 specific network routines to the
4624 lib/silcutil/win32/silcwin32net.c.
4626 * Added Unix specific utility functions from the
4627 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
4629 * Added WIN32 SILC Scheduler to the file
4630 lib/silcutil/win32/silcwin32schedule.c. The code is of course
4633 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4635 * Do not handle JOIN notify in the server if the target client
4636 is not registered (idata->registered == FALSE). The affected
4637 file is silcd/packet_receive.c.
4639 * Update the nickrec->founder in event_cumode in the Irssi SILC
4640 client. Affected file irssi/src/silc/core/silc-channels.c.
4642 * Fixed the CUMODE_CHANGE notify handling in the server when
4643 server and router are announcing their clients on channels.
4644 Now the mode changes are saved and notified correctly. The
4645 affected file is /silcd/packet_receive.c.
4647 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
4648 They really did not replace the cache entry in the ID Cache.
4649 Now they do that. Affected file silcd/idlist.c.
4651 * Fixed the KICK notify handling in the Irssi SILC client to
4652 update the channel records so that the kicked client does not
4653 appear to be on the channel. The affected file is
4654 irssi/src/silc/core/silc-channels.c.
4656 * Always update the conn->current_channel when executing command
4657 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
4659 * Fixed the KILL notify handling in Irssi SILC client to remove
4660 the killed client on all channels.
4662 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4664 * Fixed the silc_parse_command_line to remove extra spaces
4665 from the start and end of the arguments. Affected file is
4666 lib/silcutil/silcutil.c.
4668 * Cancel and free any active protocol in the function
4669 silc_server_close_connection. Affected file silcd/server.c.
4671 * Cancel and free any active protocol in the function
4672 silc_client_close_connction. Affected file is
4673 lib/silcclient/client.c.
4675 * Do not execute the KILL command for clients that are in
4676 history (ie. they are not in the network). Affected file is
4679 * Fixed KILL notify handling, client does not crash anymore.
4680 Affected file irssi/src/silc/core/silc-channels.c.
4682 * Reduced the default packet buffer size from 2048 to 1024 in
4683 lib/silccore/silcpacket.c.
4685 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
4686 counter to the SKE context that is incresed when the SKE library
4687 performs async operation outside the library. If the outside
4688 process frees the SKE context and FREED status will be set
4689 and the library will detect after the sync operation that the
4690 libary is freed. The affected files are
4691 lib/silcske/silcske[_status].[ch].
4693 * Resolve the client entry information in the function
4694 silc_client_channel_message to assure that NULL pointer is not
4695 passed as client entry to the application. */
4697 * Fixed the task timeout calculation to assure that there is
4698 never negative timeouts. The affected file is
4699 lib/silcutil/silcschedule.c.
4701 * Fixed the channel user mode notification sending in server.
4702 It was sent point-to-point to the router (or to server by router)
4703 but it needs to be destined to a channel. The routines now
4704 supports sending the channel user mode notifys to the channels
4705 when announcing clients and channels. Affected files are
4706 silcd/server.c and silcd/packet_receive.c.
4708 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
4709 It did not actually replace the old channel entry in the cache.
4710 Affected file lib/silcclient/client_notify.c.
4712 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4714 * Fixed a possible crash in silc_packet_send_prepare. It now
4715 assures always that there is enough space in the buffer and
4716 at the tail area of the buffer (for MAC).
4718 Fixed the inbound buffer reallocation in silc_packet_read.
4719 It was old code and did not handle the reallocation correctly.
4722 The affected file is lib/silccore/silcpacket.c.
4724 * Fixed buffer overflow in silc_parse_nickname in the file
4725 lib/silcutil/silcutil.c.
4727 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4729 * make install generates new server keys only if there is not
4732 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4734 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
4735 Added check that if the NOREPLY is set then we will not send
4736 the away message. This avoids infinite loop of away messages
4737 if both clients are away. The affected file is
4738 lib/silcclient/client_prvmsg.c.
4740 * Fixed client crash if /NICK was given without arguments.
4741 Affected file lib/silcclient/command.c.
4743 * Server does not send the invite list in INVITE command back
4744 to the client if the list was not altered. Added this notion
4745 to the protocol spec as well. Affected file silcd/command.c.
4747 Fixed possible crash in INVITE command by checking the
4748 value of silc_server_get_client_route command.
4750 * Fixed the INVITE notify type handling. The arguments are now
4751 taken in correct order and client does not crash. The affected
4752 file is irssi/src/silc/core/silc-channels.c.
4754 Removed the "Inviting xxx to channel" message from the
4755 client library away and let the application handle it.
4756 Affected file lib/silcclient/command.c. Added that message
4757 to Irssi SILC client's message formats.
4759 * Fixed CMODE command crash in client. It now checks the
4760 amount of arguments correctly and does not crash. The affected
4761 file is lib/silcclient/command.c.
4763 * Do not create new channel automatically in silc_channels_join
4764 but check whether the channel by that name already exists.
4765 Affected file irssi/silc/core/silc-channels.c.
4767 * Do not send the SERVER_SIGNOFF to router if the disconnected
4768 entity was the router. Affected file silcd/server.c.
4770 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
4771 SILC client as it was missing from there.
4773 Added the handling of the KICK notify to the Irssi SILC client
4774 as it was missing. Added "you have been kicked" message to
4775 Irssi SILC client's message modules formats.
4777 Added the handing of the KILL notify to the Irssi SILC client
4778 as it was missing. Added the kill message module formats
4781 The affected file is irssi/src/silc/core/silc-channels.c.
4783 * The router did not save the channel mode the server announced.
4784 Affected file silcd/packet_receive.c.
4786 * Fixed a possible crash in INFO command in server. If the
4787 server did not provide the server info it crashed. Affected
4788 file silcd/command.c.
4790 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4792 * Fixed the GETKEY command in the server to check also the
4793 global list. Otherwise the GETKEY would not work correctly
4794 in normal SILC server. Affected file silcd/command.c.
4796 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4798 * Fixed GETKEY crash, it crashed if the command did not succseed.
4800 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4802 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
4803 is now real and not just an macro interface to GMP.
4805 Removed the entire GMP from the source tree and imported new
4806 NSS MPI library instead. Reason for removing GMP is that it is
4807 extremely large and compiles extremely slow. The NSS MPI
4808 is only a few files and compiles in less than 10 seconds.
4809 The speed is also about the same as GMP. The MPI is imported
4810 to lib/silcmath/mpi.
4812 If the system has GMP installed we will still use the GMP.
4813 If it is not then the NSS MPI will be compiled.
4815 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4817 * Merged a long nickname (127 characters long) crash bugfix from
4818 Irssi CVS tree. Affected file irssi/src/core/misc.c.
4820 * Merged a freed memory reference bugfix from Irssi CVS tree.
4821 Affected file irssi/src/core/commands.c.
4823 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4825 * Added the server's public key sving and verification to the
4826 server when performing the SKE. This was missing and the
4827 remote server's (or router's) public key was accepted without
4828 checking whether we have it previously or trust it at all.
4829 Affected file silcd/protocol.c.
4831 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4833 * Check in the silc_server_timeout_remote if protocol is active
4834 and make sure that the protocol's final callback is called so
4835 that all memory if freed. Affected file silcd/server.c.
4837 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4839 * silc_server_whois_send_reply crashed the server if the nickname
4840 was 127 characters long. Affected file silcd/command.c.
4842 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4844 * Added sanity check to the silc_server_new_client. If the hostname
4845 is provided inside username then check that the provided hostname
4846 really is the same as the resolved one. If the hostname was not
4847 resolved then check it from the public key. Affected file is
4848 silcd/packet_receive.c.
4850 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
4851 if the server disconnected us and the connection is not valid
4852 anymore. Affected file irssi/src/silc/core/silc-channels.c.
4854 * Moved the silc_client_[chmode|chumode|chumode_char] away from
4855 the library to the lib/silcutil/silcutil.[ch].
4857 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4859 * Close log file after open. Affected file
4860 lib/silcutil/silclog.c.
4862 * Check whether sock == NULL in silc_client_send_packet and return
4863 if it is. Affected file lib/silcclient/silcclient.c.
4865 * Check rec->entry == NULL in the Irssi SILC Client before
4866 sending the channel message. Affecte file is
4867 irssi/src/silc/core/silc-servers.c.
4869 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4871 * Merged a splitted window bugfix from Irssi CVS tree. The
4872 affected file is irssi/src/fe-text/textbuffer-view.c.
4874 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
4875 It did not print nickname.
4877 * Improved the distributions system a bit.
4879 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4881 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
4882 irssi/src/fe-text/gui-window.c.
4884 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
4885 to in-active server. The affected file is
4886 irssi/src/silc/core/client_ops.c.
4888 * Resolve the client in USERS command reply if the entry does
4889 not have username resolved. The affected file is
4890 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
4891 command to WHOIS command to really resolve stuff. The USERS
4892 is not used any more in any critical section so WHOIS can
4893 be used even though it might be slower than IDENTIFY.
4895 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
4898 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4900 * Changed the protocol API a bit more consistent in the
4901 lib/silccore/silcprotocol.[ch].
4903 * Changed the following headers to ROBODoc format:
4905 lib/silccore/silcpayload.h
4906 lib/silccore/silcprotocol.h
4907 lib/silccore/silcsockconn.h
4909 All core library headers are now formatted.
4911 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4913 * Fixed a bug in Irssi SILC client; do not show that you are
4914 server/router operator if you really are not. Affected file is
4915 irssi/src/silc/core/client_ops.c.
4917 * Renamed silc_command_free_payload to silc_command_payload_free.
4918 Affected file lib/silccore/silccommand.h
4920 * Added silcmath.h to include the prototoypes of various routines
4921 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
4924 * Changed the following headers to ROBODoc format:
4926 lib/silccore/silcchannel.h
4927 lib/silccore/silccommand.h
4928 lib/silccore/silcid.h
4929 lib/silccore/silcidcache.h
4930 lib/silccore/silcmode.h
4931 lib/silccore/silcnotify.h
4932 lib/silccore/silcpacket.h
4933 lib/silcmath/silcmath.h
4935 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4937 * Added checking to the server code not to start the server if
4938 ciphers and stuff are not configured properly. Affected files
4939 silcd/serverconfig.[h] and silcd/server.c.
4941 * Changed the layout of the header files of the public interfaces
4942 in the SILC libraries. The new layout supports ROBODoc
4943 documentation tool (and some others) so that it is easy to create
4944 a library reference manual. All the other headers and source
4945 code must still follow the CodingStyle document. Also source
4946 code must not include these ROBODoc stuffs, only the headers.
4947 Furthermore, all public interface headers must now be named
4948 by using `silc' prefix, example: silcapi.h, silccipher.h.
4949 Some files were renamed due to this. All the other headers
4950 must not be used as public interfaces. I will update the
4951 CodingStyle document later. Changed following headers, so far:
4953 lib/silcclient/silcapi.h
4954 lib/silccore/silcauth.h
4955 lib/silccore/silcprivate.h
4956 lib/silccrypt/silcdh.h
4958 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4962 * Removed silc_client_packet_send_flush from the client library
4963 as it is not needed. Affected file lib/silcclient/client.[ch].
4965 * Added printing of message of unresolved authentication method
4966 to the Irssi SILC client. Added it to the module formats.
4967 Removed the same message from the client library.
4969 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4971 * Added new distribution feature, DISTLABEL. Every distribution
4972 can define own preprocessor label that can be used in the
4973 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
4974 file distributions, acconfig.h.pre and prepare.
4976 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4978 * Added Makefile.defines_int to include the actual definitions
4979 for Makefile.defines.in. Tested the new distribution system,
4980 created distributions and tested installation.
4982 * Added AWAY message printing to the Irssi SILC client. Added
4983 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
4985 * Added SCONNECT command to call the SILC's CONNECT command.
4986 Cannot use CONNECT directly since Irssi uses that internally.
4987 Affected file irssi/src/silc/core/silc-servers.c.
4989 Added ACTION local command. It is same as ME command but takes
4990 the channel as mandatory argument.
4992 Rewrote some of the Irssi's help files to suite for SILC
4995 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4997 * Added Makefile.defines[.in] that should for now on be included
4998 in all Makefile.am file in the source tree. That file includes
4999 all common compilation definitions for SILC source tree.
5001 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5003 * Minor changes to the ./prepare script to change the package
5004 name according the distribution name to the configure.in.
5006 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5008 * Created new distribution system. Added file `distributions'
5009 that defines all the distributions that can be created out of
5010 the SILC source tree. The ./prepare script now reads that
5011 file to determine how to prepare the distributions. The
5012 first argument to the ./prepare is the name of the distribution
5013 and second is the version of the distribution. If given
5014 without arguments it creates the default (toolkit) distribution
5015 with the default version (defined in ./prepare).
5017 All Makefile.am files that are subject to the distributions
5018 are now named as Makefile.am.pre. These are ./Makefile.am
5019 and lib/Makefile.am. Others may be changed later.
5021 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5023 * Added invite list, ban list, some key management and connection
5024 error message printing to module formats in the Irssi SILC client.
5026 * Added new silc_client_set_away_message to set the away message
5027 that is back to the person who sent private message. The
5028 affected file lib/silcclient/silcapi.h and the
5029 lib/silcclient/client_prvmsg.c.
5031 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5033 * Fixed the private message sending in the Irssi SILC client,
5034 added local command KEY to the Irssi SILC client.
5036 Added key management and key agreement message formats to the
5037 irssi/src/fe-common/silc/module-formats.[ch].
5039 Added USERS (alias WHO) printing, server/router operator
5040 indication and LIST command printing to the module formats.
5042 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5044 * Fixed channel joining notify handling, cumode notify handling
5045 from Irssi SILC client.
5047 * Added SILC specific module-formats to the Irssi SILC client so
5048 that SILC specific message hilighting, colors etc is possible.
5049 Affected file irssi/src/fe-common/silc/module-formats.[ch].
5051 Added channel mode, channel user mode, actions, notices,
5052 whois and whowas printing to the the module-formats.c.
5054 * Fixed a bug in channel deletion in the server. The channel
5055 is not left to the cache even if the channel founder auth mode
5056 is set when there are no users anymore on the channel. Affected
5057 file silcd/server.c.
5059 * The silc_net_localhost now resolves the entire hostname including
5060 the domain name. Affected file lib/silcutil/silcnet.c.
5062 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5064 * Changed the ask_passphrase client operation to be ascynchronous.
5065 It has now a completion callback and a context that the
5066 application must call after it has got the passphrase from
5067 the user. Affected files lib/silcclient/silcapi.h,
5068 lib/silcclient/protocol.c, lib/silcclient/command.c and
5071 Added SilcAskPassphrase callback that the application calls
5072 to deliver the passphrase to the library.
5074 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
5075 The public key verification and especially a certificate
5076 verification is asynchronous procedure.
5078 Added new SILC_SKE_STATUS_PENDING status to indicate the
5079 request is pending and a callback will be called to finalize
5082 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
5083 indicate that remote end did not send its public key (or
5084 certificate), even though we require it. Added check for this
5085 condition in the SKE. This was a security bug, now fixed.
5087 Defined new SilcSKEVerifyCbCompletion callback that is called
5088 when the verification process is completed.
5090 The affected files lib/silcske/silcske_status.h and
5091 lib/silcske/silcske.[ch].
5093 * Changed the verify_public_key client operation to be async
5094 as well. Defined SilcVerifyPublicKey callback that is used to
5095 indicate the success of the public key verification process.
5097 Changed the server and client to use the new async client
5100 * Changed the Irssi SILC client's internal scheduler to be called
5101 twice as many times as it used to be. As a result the client
5102 should be a bit faster now. Affected file is
5103 irssi/src/silc/core/silc-core.c.
5105 * Added support to Irssi SILC client of asynchronous public key
5106 verification and passphrase inquiry. Affected file is
5107 irssi/src/silc/core/silc-core.c.
5109 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5111 * Do not say "You have left channel %s" in client library.
5112 Moved it to the application. Affected files are
5113 lib/silcclient/command.c and silc/client_ops.c.
5115 * Fixed silc_client_get_clients. Command context was not
5116 duplicated and was freed memory in the callback. Affected
5117 file lib/silcclient/idlist.c.
5119 * Do not say "you are now talking..." on JOIN command in the
5120 client library. The appliation must handle it.
5122 * Do not say ".. changed topic to" in command reply in the
5123 client libary. The application must handle it.
5125 * Fixed TOPIC command sending in the client library.
5127 * Fixed a memory leak in silc_client_command_free in the file
5128 lib/silcclient/command.c.
5130 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5132 * Imported a modified version of Irssi client to the source tree.
5133 The Irssi will be used to create a new client called
5134 Irssi SILC. Imported to irssi/.
5136 Added silc_core_init_finish function to the Irssi. Affected
5137 file irssi/configure.in.
5139 A lot changes in the Makefile.ams around the irssi tree.
5141 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5143 * Do not rehash if the new size is same as the old size of the
5144 hash table, in the silc_hash_table_rehash*. The affected file
5145 lib/silcutil/silchashtable.c.
5147 * Replaced hash_table_del_by_context calls from the server
5148 (when channel->user_list and client->channels) to the
5149 hash_table_del as it is sufficient and faster.
5151 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5153 * Added silc_hash_table_list, silc_hash_table_get and the
5154 SilcHashTableList structure to provide an alternative way to
5155 traverse the hash table. The affected files are
5156 lib/silcutil/silchashtable.[ch].
5158 * Changed the server's idlist routines to use the hash table
5159 routines to optimize the code.
5161 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5163 * Replaced the client entry's `channel' list and channel entry's
5164 `user_list' list to hash tables for optimized lookup. Changed
5165 the code to use the hash table interface around the code.
5166 Affected file lib/silcd/idlist.[ch].
5168 * Added `auto_rehash' boolean argument to the function
5169 silc_hash_table_alloc to indicate whether the hash table should
5170 auto-rehash when it thinks is appropriate time. It will
5171 increase the hash table size if the there is twice as much
5172 entries in the table than the size of the table, and will
5173 decrease the size if there are twice as less entries than
5174 the size of the table.
5176 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5178 * Fixed silc_xxx_get_supported to not crash at some circumstances.
5180 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5182 * silc_idcache_purge_by_context deletes the entry now by context
5183 as it is supposed to do. Affected file lib/silccore/idcache.c.
5185 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
5186 client is not anymore valid (WHOWAS givens the info) and not
5187 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
5189 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5191 * Removed the `data' and `data_len' arguments from the ID Cache
5192 interfaces and added `name' argument. ID Cache does not handle
5193 anymore the binary data only a names associated with given ID.
5195 * When hashing a Client ID with silc_hash_id the entire ID is
5196 not hashed anymore, instead only the hash of the Client ID is
5197 hashed. This way we can access the Client ID from the cache
5198 with Client ID but with the hash of the ID (which is a hash of
5199 the nickname) as well without any difference in performance.
5201 Added also silc_idcache_find_by_id_one_ext to do one on one
5202 searching when we have the actual ID. Added also function
5203 silc_hash_client_id_compare. The affected files are
5204 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
5206 * When hashing the name associated with a ID it is always done
5207 in lowercase. This way we can access the cache without worrying
5208 about case-sensitivity, even though, for example nicknames are
5211 * Fixed a bug in server with channel message sending. It put
5212 wrong ID type as destination ID. The affected file
5213 silcd/packet_send.c.
5215 * silc_idcache_del_by_context now deletes from all hash tables
5216 by context. Affected file lib/silccore/idcache.c.
5218 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5220 * Changed the client library to use the new ID Cache interface.
5221 Changes around the source tree.
5223 * Added silc_hash_table_rehash_ext to rehash with specific
5224 hash function. Affected file lib/silcutil/silchashtable.[ch].
5226 * Added silc_hash_string_compare to compare two strings in the
5227 hash table. Affected file lib/silcutil/silcutil.[ch].
5229 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5231 * Added new function silc_idcache_del_by_context into the
5232 lib/silccore/idcache.[ch].
5234 * Changed the server's ID list routines to use the new ID Cache
5235 interface. Changes around the source tree.
5237 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5239 * Added silc_hash_table_del[_by_context]_ext functions in to the
5240 lib/silcutil/silchashtable.[ch].
5242 Removed silc_hash_table_find_all* routines and added new
5243 silc_hash_table_find_foreach to replace them.
5245 Added silc_hash_table_replace_ext function as extended
5246 replacing function. Separated the simple hash table interface
5247 from the extended hash table interface in the file
5248 lib/silcutil/silchashtable.h.
5250 * Fixed minor bugs and changed it to use some of the new
5251 hash table functions in lib/silccore/idcache.c
5253 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5255 * Added new function silc_hash_table_find_all to return all keys
5256 in the hash table by the specified key. As the hash table is
5257 collision resistant it also makes it possible to have several
5258 duplicate keys in the hash table. This function may be used to
5259 find all of the keys from the hash.
5261 Added user_context arguments to the SilcHashFunction,
5262 SilcHashCompare and SilcHashDestructor to deliver user specified
5265 Added new fuctions silc_hash_table_find[_all]_ext to do
5266 extended lookup with specified hash and compare functions and
5267 specified user contexts.
5269 Added new function silc_hash_table_add_ext to add the key
5270 with specified hash function and user context.
5272 Added new function silc_hash_table_foreach to traverse all
5273 entrys in the hash table. Added SilcHashForeach callback
5276 Added new function silc_hash_table_del_by_context to delete
5277 the entry only if the context associated with the key matches.
5279 Affected files are lib/silcutil/silchashtable.[ch].
5281 * Removed silc_hash_[server/client/channel]_id and added just
5282 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
5283 silc_hash_id_compare to compare two ID's using as the hash table
5284 comparison function. Added also silc_hash_data to hash
5285 binary data and silc_hash_data_compare to compare it.
5287 * Removed silc_idlist_find_client_by_hash as it is not needed
5288 anymore. Affected file silcd/idlist.[ch].
5290 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
5291 to use internally the SilcHashTable. The new ID Cache is a lot
5292 faster than the old one. Some of the ID Cache interface was also
5293 rewritten and obsolete and stupid functions were removed.
5295 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5297 * Added entry_count field to the SilcHashTable to keep the number
5298 of the entries in the table. Implemented the function
5299 silc_hash_table_rehash. Added new function
5300 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
5302 Fixed a minor bug in silc_hash_table_free.
5304 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
5305 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
5306 into the lib/silcutil/silcutil.[ch].
5308 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5310 * Implemented a collision resistant hash table into the
5311 lib/silcutil/silchashtable[ch]. See the header and the source
5312 for the SilcHashTable API.
5314 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5316 * Merged dotconf version 1.0.2 into lib/dotconf.
5318 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5320 * Do not compile anything in lib/silcsim/* if the SIM support
5321 is not enabled. The tree should now compile without problems
5324 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5326 * Compiled the SILC under cygwin. Compiled and tested briefly
5327 without problems. More tests needed. The SIMs didn't compile
5330 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
5332 * Fixed possible crash in silc_get_username in the
5333 lib/silcutil/silcutil.c.
5335 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5337 * Fixed a va_arg in silc/client_ops.c.
5339 * Oops, RC5 routines were named AES and caused some problems
5340 when not using SIM's. Affected file lib/silccrypt/rc5.c.
5342 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5344 * Added new SilcIDIP structure into the lib/silccore/id.h and
5345 replaced the old `ip' fields from all SILC ID's to that type.
5346 This is a step towards IPv6 support.
5348 The silc_id_get_len takes now the ID as an extra argument.
5349 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
5350 both IPv4 and IPv6 based ID's.
5352 The affected files are lib/silccore/id.[ch] and other files
5353 around the tree using these routines.
5355 * Removed the ID length arguments in server from various
5356 silc_server_send_notify_* routines -> they are not needed
5359 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5361 * Fixed memory leak in silc_encode_pem_file in the file
5362 lib/silcutil/silcutil.c.
5364 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5366 * Check minor version as well in the SKE. Affected files are
5367 silcd/protocol.c and lib/silcclient/protocol.c.
5369 * Added --identifier option to the server so that an identifier
5370 can be when creating the public key for the server. Affected
5371 file is silcd/silcd.c.
5373 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
5374 lib/silccrypt/silcpkcs.c.
5376 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5378 * Register default ciphers and stuff when using -C option with
5379 the server. Affected file sildc/silcd.c.
5381 * Put back the servers public key filename format, it is better
5382 than the new one. For now, the client keys are saved with the
5383 new filename format. The affected file silc/client_ops.c.
5385 * Implemented the Cipher API for the rest of the ciphers that
5386 did not implement it or implemented it the wrong way.
5388 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5390 * Register default ciphers and stuff when using the -S option
5391 in the client. Affected file silc/silc.c. Same also when
5392 creating new key pair with -C option.
5394 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5396 * Fixed the silc_verify_public_key client operation function to
5397 save the public keys differently. The fingerprint is now
5398 used as filename and not the hostname. This way also the
5399 client keys are saved uniquely and not with hostnames. The
5400 affected file is silc/client_ops.c.
5402 * Trimmed the silc_hash_fingerprint function to remove extra
5403 whitespaces from the end of the fingerprint. The affected
5404 file is lib/silccrypt/silchash.c.
5408 * Added silc_cipher_register_default function to register all
5409 default ciphers. It can be used when configuration files
5410 does not exist and the application does not want any specific
5411 ciphers in any specific order.
5413 The SilcDList is now used as silc_cipher_list dynamically
5414 allocated cipher list. Removed the static list all together
5415 and now all ciphers must be allocated to the dynamic list.
5416 The silc_cipher_alloc routine was changed to check only the
5419 All silc_cipher_* routines that used to return int returns
5422 The affected files lib/silccrypt/silccrypt.[ch].
5424 * The same thing was done to silc_hash_* as for silc_cipher_*
5425 routines. Affected files lib/silccrypt/silchash.[ch].
5427 * The same thing was done to silc_pkcs_* as for silc_cipher_*
5428 routines. Affected files lib/silccrypt/silcpkcs.[ch].
5429 Added also silc_pkcs_[un]register[_default] functions.
5430 Removed the data_context from the PKCS API.
5432 * Added silc_hmac_register_default function to register default
5433 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
5434 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
5435 to unregister all hmacs at once.
5437 * Register the default ciphers, hash functions, PKCSs and HMACs
5438 if client's configuration file does not exist. The affected
5441 * The client did not load the hash functions from the SIM
5442 modules at all. Added support for this. Affected file is
5443 silc/clientconfig.c.
5445 * When decoding public key with silc_pkcs_public_key_decode, check
5446 the supported algorithm only if PKCS are registered. Affected
5447 file lib/silccrypt/silcpkcs.c. The same was done with the
5448 silc_pkcs_private_key_decode.
5450 * Fixed the SILC List routines to keep the list always in order.
5451 It used to change the list's order when traversing the list but
5452 not it preserves the order. Affected file lib/trq/silclist.h.
5454 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5456 * Added the client library to use the SilcSocketConnection's
5457 reference counter (by silc_socket_dup) to prevent the bug that
5458 the socket object may be freed underneath async operation.
5460 * The name resolv library checking fixes in the configure.in.pre.
5463 * Created new version of the protocol drafts for future
5464 development. The -03 drafts are the ones that will be changed
5465 in the trunk now and the -02 will remain as they are.
5467 * Send list of CUMODE notifys to the router when announcing
5468 the channel users to the router. Affected file silcd/server.c.
5469 If the router receiving channel founder CUMODE for a channel
5470 that already has channel founder it will send CUMODE notify
5471 to the sender to remove the channel founder rights from the
5472 announced client. Affected file silcd/packet_receive.c.
5474 * The CUMODE notify may now use Server ID as well as the entity
5475 who changes the mode. Updated protocool specs.
5477 * Updated INSTALL and README files.
5479 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5481 * New web pages in the http://silc.pspt.fi. The pages was
5486 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5488 * Implemented the [DenyConnectin] config section in the server.
5489 Added silc_server_config_denied_conn to check whether incoming
5490 connection is denied. Affected file silcd/serverconfig.[ch].
5492 * Do not check the ports when checking the incoming configuration
5493 data if the port is 0, meaning any. Affected file is
5494 silcd/serverconfig.c.
5496 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5498 * Fixed buffer overflow in silc_string_compare in the file
5499 lib/silcutil/silcutil.c.
5501 * Fixed double free in silc_server_command_leave in the file
5504 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5506 * Fixed the version checking in the server. Affected file is
5509 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5511 * Fixed the configuration data fetching when accepting new
5512 connections in the server. Affected file silcd/server.c.
5514 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5516 * Added `sender_entry' argument to the function
5517 silc_server_packet_relay_to_channel so that we can check
5518 whether some destination actually belongs to the same route
5519 the sender belongs (ie, we must not resend the packet to the
5520 sender). Affected file silcd/packet_send.[ch].
5522 * Added `servername' field to the SilcClientEntry in the server
5523 to hold the name of the server where client is from. Affected
5524 file is silcd/idlist.h.
5526 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5528 * Moved the channel message encrypting in the router betwen
5529 router connections from silc_server_channel_message to the
5530 silc_server_packet_relay_to_channel since we want to check
5531 whether we have anybody channel before encrypting anything.
5532 Affected files silcd/packet_[receive/send].c.
5534 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5536 * Fixed the [AdminConnection] server config section to support
5537 multiple entries. Affected file silcd/serverconfig.c.
5539 * Added support into the server to check the validity of the
5540 incoming connection before executing any KE or authentication
5543 * The connection configuration is now saved to the KE and
5544 connection auth protocol contexts and not fetched anymore in
5545 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
5547 * The local hosts listenning address and port is also resolved
5548 now when starting the server. We want to have the socket object
5549 to include the real address and port for the listener. Added
5550 new function silc_net_check_local_by_sock into the files
5551 lib/silcutil/silcnet.[ch].
5553 * Fixed a broadcast bug in server -> do not broadcast if we
5556 * Fixed a routing bug. Do not route broadcast packets ever.
5557 Broadcast packets must be processed always and not routed since
5558 they may be destined to some other host than yourself and thus
5559 would get routed without no good reason. Affected file is
5562 * Added function silc_server_config_is_primary_route to check
5563 whether primary router connection has been configured (a router
5564 configuration that we are initiating). If there is not, we
5565 will assume that there is only two routers in the SILC network
5566 and we will use the incoming router connection as our primary
5567 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
5569 * Changed the order of the broadcasting. Broadcast _after_ the
5570 packet has been processed not before. Affected file is
5573 * Fixed a [ClientConnection] parsing bug. The port was never
5574 parsed correctly thus resulting to port 0. Affected file
5575 silcd/serverconfig.c.
5577 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
5578 argument and did not set the broadcast packet flag. Affected
5579 file silcd/packet_send.c. Fixed same bug in the function
5580 silc_server_send_notify as well.
5582 * If we receive NEW_ID packet for our own ID in the server, ignore
5585 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5589 * Removed the nickname from the Private Message Payload.
5590 Updated the code and the protocol specs.
5592 * Updated protocol specs for submitting to the IETF.
5594 * Tweaked the Random Number Generator a bit. Affected file
5595 lib/silccrypt/silcrng.c. Exported a new function
5596 silc_rng_[global]_add_noise which can be used to add more
5599 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5601 * Do not parse packets with different timeout when protocol
5602 is active -> may cause problem with rekey. Affected file
5605 * When server receives signoff notify it must not create
5606 new channel key if the client is on any channels since the
5607 sender of the signoff notify will create it.
5609 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5611 * Added printing of error messages during SKE protocol from the
5612 failure packet sent by server during SKE. Affected file
5615 * Removed the client's failure_callback handling with timeout
5616 and handle it immediately when received.
5618 * The SKE library returned wrong type in SUCCESS and FAILURE
5619 packets. They must be 32 bit MSB not 16 bit MSB.
5621 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5623 * Ok, rewrote the logic of the re-key and now it seems to work.
5624 I tested it on high traffic with frequent re-keys without
5625 problems. Added hmac_receive (and renamed hmac to hmac_send)
5626 in SilcClientConnection in lib/silcclient/client.h and
5627 in SilcIDListData in silcd/idlist.h. Also, removed the
5628 SilcPacketParserContext's cipher and hmac fields as they are
5629 not needed anymore and actually caused some problems when
5630 the ciphers and hmac's changed underneath the packet parser.
5632 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5634 * If re-key protocol is active then process the incoming packets
5635 synchronously since we must assure that icoming packets encrypted
5636 with the old key is processed before the new keys is set to
5637 use. This is true other packets than for REKEY packets.
5638 Affected file silcd/server.c. The same was done to client library
5639 as well, affected file lib/silcclient/client.c.
5641 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5643 * Fixed bug in client and server to accept the force send if
5644 the packet is send from silc_[server/client]_packet_process
5645 function. Otherwise the packets are never delivered, oops.
5647 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5649 * Disable force sending of packets when REKEY protocol is active.
5650 We must assure that no packet is sent directly when rekey is
5651 performed. All packets must be sent through packet queue.
5652 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
5653 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
5654 function is silc_[server/client]_packet_send_real to check
5657 * Replaced the SIM paths from example config files to
5658 /usr/local/modules. Also, make install creates now
5659 /usr/local/silc/logs directory to hold all the SILC server
5662 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5664 * Made the configure.in.pre work on Solaris. Patch by salo.
5666 * Made all ciphers compatible with non-x86 machines. Defined
5667 CBC mode macros into lib/silccrypt/ciphers_def.h.
5669 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5671 * Fixed the make install.
5673 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5675 * When MAC computation fails the silc_packet_decrypt returned 0
5676 even though it was supposed to return -1. Fixed this. The
5677 affected file is lib/silccore/silcpacket.c.
5679 * Do not replace the config files in /etc/silc (in make install)
5680 if they already exist. Affected file ./Makefile.am.
5682 * Do not send re-key packets immediately but through packet queue.
5683 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
5685 * Changed silc_net_check_host_by_sock to return FALSE if the
5686 IP/DNS could not be resolved. Though, it returns the IP address
5687 now even if it could not resolve it (but returns also FALSE).
5688 Affected file lib/silcutil/silcnet.[ch].
5690 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5692 * Added silc_pkcs_decode_identifier to decode the public key's
5693 identifier. Affected file lib/silccrypt/silpkcs.[ch].
5694 Added also silc_pkcs_free_identifier. Added also new context
5695 SilcPublicKeyIdentifier.
5697 * Added -S option to the silc client. It is used to dump the
5698 contents of the specified public key file.
5700 * Changed the PKCS api to return the public key length when
5701 setting the public key.
5703 * Fixed a fatal bug in the public and private key file loading.
5704 Affected file lib/silccrypt/silcpkcs.c.
5706 * Execute the packet parsing for client with zero (0) timeout
5707 if the protocol is active. Affected file silcd/server.c.
5709 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5711 * Made the key generation options to the silcd program. Added
5712 -C option, equivalent to client's option.
5714 * Added new [ServerKeys] config section to the server. It
5715 configures the server's public and private key.
5717 * Defined generic Public Key Payload into the protocol
5718 specification to send specific type of public keys and
5721 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
5722 public key or certificate.
5724 * Implemented the GETKEY command to the server and to the
5725 client library and on user interface.
5727 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5729 * Made preliminary `make install' work.
5731 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5733 * Added SilcServerRekey context into silcd/idlist.h.
5735 * Added the PFS support as defined in the specification to the
5736 SKE protocol. Affected files lib/silcske/*.c.
5738 * Added `ske_group' field to the SilcServerRekey context to hold
5739 the number of the SKE group that is used with PFS in re-key.
5740 Affected file silcd/idlist.h.
5742 * Added PFS re-key support to the server. Affected file is
5745 * Added silc_protocol_cancel to cancel execution of the next
5746 state of the protocol. Affected file is
5747 lib/silccore/silcprotocol.[ch].
5749 * Added the re-key support with and without PFS to the client
5750 library. Re-key is performed once in an hour, by default.
5752 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
5753 Added silc_client_rekey_callback and silc_client_rekey_final.
5754 Affected files are lib/silcclient/protocol.[ch] and
5755 lib/silcclient/client.[ch].
5757 * Removed the `hmac_key' and `hmac_key_len' fields from the
5758 SilcClientConnection structure; not needed. Affected file is
5759 lib/silcclient/client.h.
5763 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5765 * Do not ask whether user wants to use the negotiated private key
5766 for private messages, just use it. Affected file is
5767 silc/local_command.c.
5769 * Added `send_enc_key' and `enc_key_len' fields to the
5770 SilcIDListData structure since they are needed in the re-key
5771 phase. Affected file is silcd/idlist.[ch].
5773 * Implemented the simple re-key protocol into the server.
5774 Affected files silcd/server.c and silcd/protocol.[ch]. The
5775 re-key will be performed once in an hour, by default.
5777 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
5778 Added silc_server_rekey, silc_server_rekey_callback and
5779 silc_server_rekey_final.
5781 * Removed Tunneled flag from the protocol. Updated the code
5782 and the specifications.
5784 * Adde `pfs' field to the SilcIDListData to indicate whether
5785 the PFS is to be performed in the re-key. Affected file is
5788 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5790 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
5791 int64 of at least the xintXX size. If void * is less that 4
5792 bytes uint32 * will be used. Defined bool as boolean.
5794 * Changed _ALL_ unsigned long and unsigned int to uint32,
5795 unsgined short to uint16 in the source tree.
5797 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
5798 not handle clients that has entry->data.registered == FALSE.
5799 They are not in the network anymore. Affected file is
5802 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5804 * Implemented the sending of the SERVER_SIGNOFF notify in the
5805 server. Affected file is silcd/server.c.
5807 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
5808 Added also silc_notify_payload_encode_args into the
5809 lib/silccore/silcnotify.[ch].
5811 * Implemented ther SERVER_SIGNOFF notify handling in the server.
5812 Affected file silcd/packet_receive.c.
5814 * Implemented the SERVER_SIGNOFF notify handling in the client
5815 library. Affected file lib/silcclient/client_notify.c. Also,
5816 implemnted the printing of the SERVER_SIGNOFF info to the
5817 application. Affected file silc/client_ops.c.
5819 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
5820 if the deleting was successful. Affected file silcd/idlist.[ch].
5822 * Added support for public key authentication in the connection
5823 authentication protocol in the client library. Affected file
5824 lib/silcclient/protocol.c.
5826 * Changed the server's silc_idlist_get_clients_by_* interface
5827 to support already allocated array so that new entries may be
5828 added to pre-allocated array. Affected file silcd/idlist.[ch].
5829 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
5830 and command replies.
5832 * All command reply functions in the server now calls the
5833 pending command callback even if error occured. This way the
5834 error will be delivered to the client as well. Affected files
5835 silcd/command.c and silcd/command_reply.c.
5837 * Fixed INFO command to return local server's info if no server
5838 was provided. Affected file lib/silcclient/command.c.
5840 * Removed RESTART command for good. Updated the code and the
5843 * Rewrote parts of the task system. It is a bit simpler now.
5844 Removed unsued task priorities. The affected files are
5845 lib/silcutil/silctask.[ch].
5847 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5849 * Moved the USERS printing from the library to the application.
5850 Affected files lib/silcclient/command.c and silc/client_ops.c.
5852 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5856 * Added channel key re-key support. The re-key is perfomed
5857 only by the router and is done once in an hour. Added `rekey'
5858 field to the SilcChannelEntry in the server. Affected files
5859 silcd/server.c and silcd/idlist.h.
5861 * Added silc_task_unregister_by_context into the file
5862 lib/silcutil/silctask.[ch].
5864 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5866 * Added SILC_UMODE_GONE mode to indicate when the client is not
5867 present in the SILC network. Added also support to the local
5868 command AWAY that will set this mode. Added support of showing
5869 "xxx is gone" in WHOIS command. The USERS command shows the
5870 gone status as well.
5872 * Fixed setting server and router operator privileges in the
5873 server's UMODE command. Affected file silcd/command.c.
5875 * Merged the SKE KE1 and KE2 payloads into one payload. The
5876 new KE payload is equivalent to the old KE2 payload.
5878 Cleaned up the SKE Start Payload parsing. It now uses the
5879 simple buffer unformatting to do the parsing. A lot faster
5882 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
5883 to the SKE that is used to indicate whether both of the SKE
5884 parties should perform authentication. By default only the
5885 responder performs authentication. By setting this flag also
5886 the initiator must do authentication. By default it is unset
5887 since in normal SKE case, client to server connection, only
5888 the responder should do authentication. When doing SKE between
5889 two clients both should perform authentication. Updated the
5890 code and the protocol specs.
5892 * A little fix to IDENTIFY command in the server. Search the
5893 client first by hash not nickname. Affected file is
5896 * Fixed the silc_client_close_connection to support closing
5897 the client to client connections wihtout deleting too much
5898 data. Affected file lib/silcclient/client.c.
5900 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
5901 are received if protocol used to be active but is not anymore
5902 the application would crash due to NULL pointer dereference.
5903 Affected files silcd/server.c and lib/silcclient/client.c.
5905 * Added `hash' field to the SilcClientConnection to include
5906 the hash function negotiated in the SKE protocol.
5908 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
5909 to set the channel founder authentication data. A client can
5910 claim the founder rights later by providing the authentication
5911 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
5912 This way the channel founder can regain the channel founder
5913 privileges even it is left the channel. This works only on
5914 local server and the client must be connected to the same
5915 server to be able to regain the founder rights. Updated the
5916 protocol specs accordingly.
5918 Added support to the CMODE command in the client to set the
5919 founder auth data. Read the README to see how to set it.
5921 Added support to the CUMODE command to claim the founder
5922 rights. Read the README to see how to do it.
5924 Added support for the founder authentication to the Channel
5925 Entry in the server. Affected file silcd/idlist.h.
5927 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
5928 server's CMODE command. Affected file silcd/command.c.
5930 * Added the following new functions into lib/silccore/silcauth.[ch]:
5931 silc_auth_get_method and silc_auth_get_data.
5933 * The server now saves the remote hosts public key to the
5934 SilcIDListData pointer. Affected file silcd/protocol.c.
5936 * The normal server now does not remove the channel entry from
5937 the cache if the founder authentication data is set. It used
5938 to remove it if the founder was the last one on the channel on
5939 the server and left the channel. The auth data is saved and
5940 if the channel is re-joined later the old entry is used with
5941 the old auth data. Affected files silcd/command_reply.c and
5944 * Removed the `pkcs' field from the SilcIDListData structure
5945 in the server; it is not used. Affected file silcd/idlist.h.
5947 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5949 * Fixed packet processing on slow links. Partial packets were
5950 never re-processed because the incoming data buffer was cleared
5951 by the application. Application must not directly clear the
5952 sock->inbuf, the packet processing routines handle it. Fixed
5953 this in client library and in server.
5955 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5957 * Fixed the WHOIS and IDENTIFY send reply function to really
5958 check whether to send list or just one entry. Affected file
5961 * Cleaned up the LEAVE command's channel key distribution. The
5962 affected file silcd/command.c.
5964 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
5965 can enforce the channel mode as well. In that case the ID
5966 includes the ID of the server. The code now enforces the
5967 mode change if the router have different mode than the server.
5969 * The notify client operation with CMODE_CHANGE notify can now
5970 return NULL client_entry pointer if the CMODE was not changed
5971 by client. Application must check for this.
5973 * Added <Server ID> argument to INFO command to support server
5974 info fetching by Server ID.
5976 * Added silc_server_announce_get_channel_users to get assembled
5977 packets of channel users of the specified channel. Affected
5978 file silcd/server.[ch].
5980 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
5981 was freed underneath the ID Cache.
5983 * Re-announce clients when the server received CHANNEL_CHANGE
5984 notify from the router. Affected file silcd/packet_send.c.
5986 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5988 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
5989 crashed since it did not handle the fact that there is no cipher
5990 called "3" and didn't check the error condition. Now fixed.
5992 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
5993 flag. It can be used to send message requests.
5995 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5997 * Implemented the RESTART command in the client.
5999 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
6000 notice type messages. Added notice printing to the user
6003 * The channel keys are not re-generated if the channel's mode
6004 is PRIVKEY, ie private key on the channel exists. Affected
6005 files silcd/server.c and silcd/command.c.
6007 * Fixed a little bug in channel message delivery when channel
6008 private keys are set in the server. Affected file is
6009 silcd/packet_send.c.
6011 * Changed the setting on channel->on_channel = TRUE from the
6012 silc_client_save_channel_key to the JOIN command reply. The
6013 key payload is not received if the private channel key is set.
6014 Affected file lib/silcclient/command_reply.c and the
6015 lib/silcclient/client_channel.c.
6017 * When the CMODE_CHANGE notify is sent and the channel private
6018 key mode is removed the channel key must be re-generated in
6019 other cells as well. Added this support for the router in the
6020 silcd/packet_receive.c.
6022 * Added new local command NOTICE to send notice message on
6023 channel. Affected file silc/local_command.[ch].
6025 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6027 * Added new local command ME to the client. It is used to send
6028 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
6029 some action. Affected file silc/local_command.[ch].
6031 * Changed channel_message and private_message client operations
6032 to deliver the message flags to the application. Added also
6033 the `flags' arguments to the silc_client_send_channel_message
6034 and silc_client_send_private_message functions. Affected file
6037 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6039 * Redefined the Private Message Payload to support private message
6040 keys and to support the new private message flags. Updated
6041 the protocol specs. Flags makes it possible to have for example
6042 CTCP style messages.
6044 * Added new type SilcPrivateMessagePayload and defined an API
6045 for it in the lib/silcclient/silcprivate.[ch].
6047 * Tested private message private keys successfully. Tested the
6048 private message key set, unset and list commands with the new
6051 * Redefined the Channel Message Payload to include the channel
6052 message flags (equal with private message flags) to support
6053 for example CTCP style messages.
6055 * Defined some of the message (for channel and private message)
6056 flags. Updated the protocol specs and added the flags to the
6057 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
6059 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6061 * Added SilcKeyAgreementStatus type to the key agreement routines
6062 to indicate the current status and error if one occured.
6063 The status types are defined in the lib/silcclient/silcapi.h.
6065 * Added new local command KEY that is used to set and unset private
6066 keys for channels, set and unset private keys for private messages
6067 with remote clients and to send key agreement requests and
6068 negotiate the key agreement protocol with remote client. The
6069 key agreement is supported only to negotiate private message keys,
6070 it currently cannot be used to negotiate private keys for channels,
6071 as it is not convenient for that purpose.
6073 * Fixed a minor pending callback setting bug in the function
6074 silc_client_get_client_by_id_resolve, now the function works.
6075 Affected file lib/silcclient/idlist.c.
6077 * Added function silc_net_get_local_port to get local bound
6078 port by socket. Added to lib/silcutil/silcnet.[ch].
6080 * Added `sockets' and `sockets_count' fields to the SilcClient
6081 object. They hold the sockets of the listenning sockets in
6082 the client. Listenning sockets may be for example the key
6083 agreement server. Affected file lib/silcclient/client.[ch].
6084 Added functions the silc_client_add_socket and the
6085 silc_client_del_socket. They are exported to the application
6088 * Added ~./silc/clientkeys to support other client's public keys.
6090 * Renamed verify_server_key client operation to verify_public_key
6091 and added one argument to indicate the type of the connection
6092 (server, client etc.).
6094 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6096 * Added silc_server_connection_auth_request to handle the
6097 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
6098 silcd/packet_receive.[ch].
6100 * Added silc_server_send_connection_auth_request into the
6101 silcd/packet_send.c to send the connection auth request packet.
6103 * Cleaned up the silcd/protocol.c a bit and fixed some memory
6106 * Fixed the public key authentication in responder side in the
6107 server. The `auth_data' pointer includes the SilcPublicKey
6108 not the path to the public key. Affected file silcd/protocol.c.
6110 * Implemented the public key authentication in the initiator side
6111 in the server. Affected file silcd/protocol.c.
6113 * Removed the [RedirectClient] config section from the server
6114 configuration. Is not needed and I don't want to implement it.
6116 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6118 * Cleaned up the CMODE command in the server. It now works
6119 correctly and supports all the modes defined in the protocol.
6120 Affected file is silcd/command.c.
6122 * Added `hmac_name' field to the SilcChannelEntry in the server
6123 to hold the default HMAC of the channel. It can be set when
6124 creating the channel (with JOIN command). Affected files
6127 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
6128 type to indicate the change of the current cipher and hmac
6129 on the channel. Client can safely ignore the <cipher> argument
6130 (if it chooses to do so) since the CHANNEL_KEY packet will
6131 force the channel key change anyway. The <hmac> argument is
6132 important since the client is responsible of setting the new
6133 HMAC and the hmac key into use.
6135 * Fixed the CMODE command in the client library as well.
6137 * Tested CMODE command in router environment successfully.
6139 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6141 * Show the version of the remote client (or server) when connecting
6142 to the server. It is logged to the log file. Affected file
6143 is silcd/protocol.c.
6145 * Fixed the KILLED notify handling in the client library. The
6146 client must be removed from all channels when receiving the
6149 Also, do not remove the client entry when giving the KILL
6150 command but when the KILLED notify is received.
6152 * Removed silc_idlist_find_client_by_nickname from the server.
6153 Not needed anymore. Affected files silcd/idlist.[ch].
6155 * Implemented the CHANNEL_CHANGE notify type handling to the
6156 server. Affected file silcd/server.c.
6160 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6162 * Added silc_server_send_notify_invite to send the INVITE
6163 notify between routers.
6165 * Implemented the INVITE command correctly to the server.
6167 * Implemented the INVITE notify type handling in the server.
6169 * Implemented the INVITE command to the client library and on the
6172 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6174 * Added function silc_server_get_client_resolve to find the
6175 client entry by ID from all ID lists and then resolve it
6176 (using WHOIS) if it cannot be found. Affected file is
6179 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6181 * Implemented the BAN command to the client library.
6183 * The JOIN command in the server now checks the invite list
6186 * Changed the silc_command_reply_payload_encode_va and the
6187 silc_command_payload_encode_va to support that if argument is
6188 NULL it ignores and checks the next argument. Affected file
6189 lib/silccore/silccommand.c.
6191 * Added silc_server_send_notify_ban to send the BAN notify
6192 type between routers.
6194 * Chaned the silc_notify_payload_encode to support that if
6195 argument is NULL it ignores and checks the next argument.
6196 Affected file lib/silccore/silcnotify.c.
6198 * Tested ban lists in router environment successfully.
6200 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6202 * Implemented BAN command to the server, in silcd/command.[ch].
6204 * Removed the BAN and INVITE_LIST modes from the CMODE command
6207 * Added function silc_string_match to regex match two strings.
6208 Affected files lib/silcutil/silcutil.[ch].
6210 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6212 * Redefined parts of the SilcChannelEntry in the server to support
6213 the new ban and invite lists.
6215 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6217 * Redefined the INVITE command. The same command can be used to
6218 invite individuals to the channel but also to manage the invite
6219 list of the channel (to add to and remove from the invite list).
6220 Updated the protocol specs.
6222 * Added new command SILC_COMMAND_BAN that can be used to manage
6223 the ban list of the channel. Updated the protocol specs.
6225 * Removed the channel modes: the SILC_CMODE_BAN and the
6226 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
6227 in the CMODE command. The equivalent features are now available
6228 using INVITE and BAN commands. Updated the protocol specs.
6230 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
6231 in the network about change in the current ban list. The notify
6232 type is not used by the client.
6234 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
6235 support the invite lists.
6237 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6239 * Added new function silc_string_regexify that converts string
6240 including wildcard characters into regex string that can
6241 be used by the GNU regex library. Added into the file
6242 lib/silcutil/silcutil.[ch].
6244 Added silc_string_regex_combine to combine to regex strings
6245 into one so that they can be used as one regex string by
6246 the GNU regex library. Added into the file
6247 lib/silcutil/silcutil.[ch].
6249 Added silc_string_regex_match to match two strings. It returns
6250 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
6252 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6254 * Imported GNU regex to the soruce tree into lib/contrib.
6255 Fixed some compiler warning from the regex.c.
6257 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6259 * Fixed MOTD command in the server to work in router environment.
6261 * Fixed the MOTD command in the client library to support
6262 the server argument in the command.
6264 * Added `nickname_len' argument to the silc_idlist_add_client
6265 in the server, as the `nickname' argument may be binary data
6268 * Added silc_idlist_get_channels to return all channels from
6271 * Implemented LIST command to the server. Affected file is
6274 * Implemented the LIST command to the client library and on the
6277 * Added [<user count>] argument to the LIST command reply.
6278 With private channels the user count is not shown.
6280 * Updated TODO and README.
6282 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6284 * The client entry's data.registered must be TRUE even with
6285 global client entry on global client list. The data.registered
6286 is used to check whether the client is anymore in the network,
6287 for example with WHOWAS command so it must be valid.
6289 * Fixed the WHOWAS command in the server. It now actually works
6290 in router environment. Added function into silcd/command_reply.c
6291 silc_server_command_reply_whowas_save.
6293 * Added silc_idlist_purge function to the silcd/idlist.c
6294 to periodically purge the ID Cache.
6296 * Fixed INFO command in the server. It works now in router
6297 environment. Added <server name> argument to the INFO command
6298 reply. Updated the protocol specs.
6300 * Fixed minor bug in silc_idcache_purge to not purge if the
6301 expire value is zero.
6303 * Fixed various bugs in WHOIS and IDENTIFY command handling as
6304 they were buggy because of the WHOWAS information.
6306 * Fixed local command MSG to handle the async resolving of
6307 the remote client properly. It used to fail the first MSG.
6308 Affected file silc/local_command.c.
6310 * Added `data_len' field to SilcIDCache context.
6312 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6314 * Update TODO. Todo in commands in the server.
6316 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6318 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
6319 used by routers as broadcast packet to inform other routers
6320 about the changed user mode.
6322 Implemented the notify handling in the server. Affected file is
6323 silcd/packet_receive.c. Added the function
6324 silc_server_send_notify_umode to the silcd/packet_send.[ch].
6326 * Added new generic Channel Payload and deprecated the New Channel
6327 Payload. The New Channel Payload is now the generic Channel
6330 * Added new argument `mode' to the silc_server_send_new_channel
6331 as it is required in the Channel Payload now.
6333 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
6334 and created a new and real SilChannelPayload to represent the
6335 new generic Channel Payload. Implemented the encode/decode
6336 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
6338 * Added silc_server_get_client_channel_list to return the list
6339 of channels the client has joined for WHOIS command reply.
6340 Affected file silcd/server.[ch].
6342 * Implemented the channel list sending in the WHOIS command reply
6343 in server and in the client.
6345 Implemented the channel list displaying on the user interface
6346 as well. Affected file silc/client_ops.c.
6348 * Added silc_channel_payload_parse_list to parse list of Channel
6349 Payloads. It returns SilcDList list of SilcChannelPayloads.
6350 Client for example can use this function to parse the list of
6351 channels it receives in the WHOIS command reply. The caller
6352 must free the list by calling silc_channel_payload_list_free.
6353 Affected files lib/silccore/silcchannel.[ch].
6355 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6357 * Added one new argument <user mode> to the WHOIS command reply
6358 to return the mode of the user in SILC. Updated the protocol
6361 Implemented it to the server and client.
6363 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6365 * Fixed the mode printing on the user interface on joining.
6366 Affected file silc/client_ops.c.
6368 * Implemented the UMODE command and user modes in general to the
6369 client library and to the user interface.
6371 * Implemented the UMODE command to the server.
6373 * The server now sends UNKNOWN_COMMAND error status if client sends
6374 unknown command. Affected file silcd/command.c.
6376 * All server commands now handle the command identifier the right
6377 way when sending the command reply to the client. The client can
6378 use to identify the command replies with the identifier.
6380 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6382 * Added silc_server_get_client_route to resolve the route to
6383 the client indicated by the client ID. Affected file is
6386 * Added silc_server_relay_packet as general function to relay
6387 packet to arbitrary destination. This deprecates functions
6388 like _send_private_message_key, _relay_notify etc. Affected
6389 file is silcd/packet_send.[ch].
6391 Removed silc_server_send_key_agreement,
6392 silc_server_send_private_message_key and
6393 silc_server_packet_relay_notify functions from the file
6394 silcd/packet_send.[ch].
6398 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
6399 server. Affected file silcd/packet_receive.[ch].
6401 * Implemented the KILL command to the client. Implemented the
6402 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
6403 Affected files lib/silcclient/command[_reply].c and
6404 lib/silcclient/client_notify.c. Implemented the KILL notify
6405 printing in the user inteface.
6407 * Fixed a lot silc_parse_nick memory leaks from the client
6408 library in the file lib/silcclient/command.c.
6410 * Changed the silc_server_send_notify_on_channels's `sender'
6411 argument from SilcSocketConnection to SilcClientEntry to
6412 check the sender as entry and not as connection object and not
6413 to send to the client provided as argument. The affected file
6414 is silcd/packet_send.[ch].
6416 * The notify packets that are destined directly to the client used
6417 to not to be processed by the server. Now changed that and the
6418 server processes all notify packets. After relaying the packet
6419 to the client the notify packet is processed in the server.
6421 * The silc_server_free_client_data now checks whether there is
6422 pending outgoing traffic for the client and purges the data to
6423 the network before removing the client entry.
6425 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6427 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
6428 an client is killed from the SILC Network. Updated the protocol
6431 Added new function silc_server_send_notify_killed to the
6432 silcd/packet_send.[ch].
6434 * Added function silc_server_packet_relay_notify to relay notify
6435 packets that are destined directly to a client. In this case
6436 the server does not process the notify packets but merely relays
6437 it to the client. Affected file silcd/packet_send.[ch].
6439 Added also silc_server_packet_process_relay_notify to check
6440 whereto relay the notify. Affected file is
6441 silcd/packet_receive.[ch].
6443 * Implemented the KILL command to the server.
6447 * Added the backup schema desgined last fall to the protocol
6448 specs for everyone to see. The specification is in the
6449 *-spec-xx.txt draft and the packet type definitions for the
6450 backup routers is in *-pp-xx.txt draft. Thusly, added also
6451 new packet type SILC_PACKET_CELL_ROUTERS.
6453 * A big security problem in the implementation discovered. The
6454 signoff of an client did not cause new channel key generation
6455 which it of course should've done. The channel keys must be
6456 always re-generated when client leaves (or signoffs) the channel.
6457 The silc_server_remove_from_channels funtion now handles
6458 the channel key re-generation.
6460 * Added `sender' argument to the silc_server_send_notify_on_channels
6461 to not to send the client provided as argument. Affected file
6462 silcd/packet_send.[ch].
6464 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6466 * Implemented OPER and SILCOPER commands into the server and
6469 * Added silc_auth_verify and silc_auth_verify_data to verify
6470 the authentication directly from the authentication payload.
6471 It supports verifying both passphrase and public key based
6472 authentication. Affected file lib/silccore/silcauth.[ch].
6474 * Added `hash' field to the SilcIDListData structure. It is the
6475 hash negotiated in the SKE protocol. Affected file is
6478 * Slight redesigning of the SilcAuthPayload handling routines.
6479 Do not send SilcPKCS but SilcPublicKey as argument.
6481 * Implemented the public key authentication support to the
6482 serverconfig. The public key is loaded from the provided path
6483 and saved as authentication data to void * pointer. Thus,
6484 changed the unsigned char *auth_data to void *auth_data;
6486 * Fixed SHUTDOWN command to send the reply before the server
6487 is shutdown. :) Affected file silcd/command.c.
6489 * Fixed fatal bug in CONNECT command. The hostname was invalid
6490 memory and server crashed. Affected file silcd/command.c.
6492 * Fixed fatal bug in CLOSE command. The server_entry became
6493 invalid but was referenced later in the command. Affected file
6496 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6498 * Fixed fatal bug in failure packet handling. Server ignored
6499 the failure and thus crashed when it came.
6503 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6505 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
6506 that the command may be executed only once in (about) 2 seconds.
6507 The old SILC_CF_LAG flag is same but allows command bursts up
6508 to five before limiting.
6510 Added the support for CF_LAG and CF_LAG_STRICT flags to the
6511 server code. Various commands now includes the CF_LAG_STRICT
6512 flag to disallow any kind of miss-use of the command.
6514 * Fixed the silc_buffer_unformat to not to allocate any data
6515 if the length of the data is zero. It used to allocate the
6516 length + 1. Affected file lib/silcutil/silcbuffmt.c.
6518 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6520 * Changed the format of AdminConnection configuration section
6521 in the server. Added username of the admin to the format.
6522 Affected files silcd/serverconfig.[ch].
6524 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
6525 to return admin configuration data by host, username and/or
6528 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6530 * Implemented WHOWAS command to the server. Added the functions:
6532 silc_server_command_whowas_parse,
6533 silc_server_command_whowas_send_reply,
6534 silc_server_command_whowas_from_client and
6535 silc_server_command_whowas_from_server
6537 * Added <Client ID> argument to the WHOWAS command reply. Updated
6538 the protocol specs accordingly.
6540 * Implemented WHOWAS command and command_reply to the client
6543 Implemented the WHOWAS printing on the user interface.
6545 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6547 * Added new argument to the WHOWAS command reply, the real name.
6548 It is an optional argument. Updated the protocol specs.
6550 * Added SilcIDCacheDestructor callback that is registered when
6551 the SilcIDCache is allocated. The callback is called when
6552 an cache entry in the ID Cache expires, or is purged from the
6553 cache. Added into lib/silccore/idcache.[ch].
6555 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
6556 to destruct the client entries when the cache entry expires.
6557 Other ID Cache's in server and in the client library ignores
6560 * If the ID Cache entry's `expire' field is zero then the entry
6561 never expires. Added boolean `expire' argument to the
6562 silc_idcache_add function in the lib/silccore/idcache.[ch].
6563 If it is TRUE the default expiry value is used.
6565 * Added silc_server_free_client_data_timeout that is registered
6566 when client disconnects. By default for 5 minutes we preserve
6567 the client entry for history - for WHOWAS command.
6569 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6571 * Added support to the server to enforce that commands are not
6572 executed more than once in 2 seconds. If server receives
6573 commands from client more frequently, timeout is registered
6574 to process the commands. Affected file silcd/command.c.
6575 Added new function silc_server_command_process_timeout.
6577 * Changed NICK_NOTIFY handling in client library to check that
6578 if the client's nickname was changed, so there is no need to
6579 resolve anything from the server.
6581 * Removed error printing from the WHOIS and IDENTIFY commands.
6582 If error occurs then it is ignored silently in the client library.
6583 The application, however, may map the received error to
6584 human readable error string. The application currently maps
6585 the NO_SUCH_NICKNAME error to string.
6587 * Made the command status message public to the application. Moved
6588 them from lib/silcclient/command_reply.c to
6589 lib/silcclient/command_reply.h. The application can map the
6590 received command status to the string with the
6591 silc_client_command_status_message function.
6593 * Added check to the server to check that client's ID is same
6594 as the Source ID in the packet the client sent. They must
6597 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6599 * Added dist-bzip hook to the Makefile.am to make bzip2
6600 compressed distributions.
6602 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6604 * Server now enforces the maximum length for the nickname and
6605 the channel as protocol specification dictates. 128 bytes for
6606 nickname and 256 bytes for channel name.
6608 * Moved the WHOIS printing to the application. The client libary
6609 does not print out the WHOIS information anymore, the application
6610 must do it. Renamed silc_client_command_reply_whois_print to
6611 the silc_client_command_reply_whois_save.
6613 The client's idle time is also sent to the application now, and
6614 the idle is shown on screen.
6616 * Added silc_client_command_reply_identify_save to save the
6617 received IDENTIFY entries.
6619 * Do not check for channel private keys in message sending and
6620 reception if the channel does not have the PRIVKEY mode set.
6621 Affected file lib/silclient/client_channel.c.
6623 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6625 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
6626 just surfaced after chaning the JOIN procedure.
6628 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6630 * Added silc_client_get_clients_by_list to get client entries
6631 from Client ID list, that is returned for example by JOIN
6632 and USERS command replies. The application should use this
6633 function for example when JOIN command reply is received to
6634 resolve the clients already on the channel (library does not
6635 do that anymore as USERS command reply is not used in the JOIN
6636 procedure anymore). Affected files lib/silcclient/silcapi.h and
6637 lib/silcclient/idlist.c.
6639 * JOIN command reply and USERS command reply returns now SilcBuffer
6640 pointers instead of unsigned char pointers when returning
6641 the client list and mode list.
6643 * Added <Client ID> argument to the JOIN command reply, mainly
6644 for the server to identify for which client the command was
6645 originally sent. Updated protocol specs accordingly.
6647 * Added SilcDlist private_key pointer to the SilcChannelEntry
6648 in the client to support the channel private keys. Affected
6649 file is lib/silcclient/idlist.h.
6651 * Added SilcChannelPrivateKey argument to the function
6652 silc_client_send_channel_message so that application can choose
6653 to use specific private ke if it wants to. If it is not provided,
6654 the normal channel key is used, unless private keys are set.
6655 In this case the first (key that was added first) is used
6656 as the encryption key.
6658 * Implemented the support for channel private key handling.
6659 Implemented the following functions:
6661 silc_client_add_channel_private_key,
6662 silc_client_del_channel_private_keys,
6663 silc_client_del_channel_private_key,
6664 silc_client_list_channel_private_keys and
6665 silc_client_free_channel_private_keys
6667 Affected file lib/silcclient/client_channel.c.
6669 * Added the support for the private keys in the channel message
6670 sending and encryption and in the message reception and
6671 decryption. Affected funtions are
6672 silc_client_send_channel_message and silc_client_channel_message.
6674 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6676 * Added SKE's key verify callback to the client library's
6677 KE protocol context. Affected files lib/silcclient/protocol.[ch].
6679 * Removed the statement that server (or router) must send USERS
6680 command reply when joining to the channel so that the client
6681 knows who are on the channel. Instead, the client list and
6682 client's mode list is now sent in the JOIN command reply to the
6683 client who joined channel. This is better solution.
6685 * Added function silc_server_get_users_on_channel and function
6686 silc_server_save_users_on_channel to the silcd/server.[ch].
6688 * Removed function silc_server_command_send_users from the
6691 * Do not show topic on the client library anymore. The topic is
6692 sent in the command reply notify to the application and the
6693 application must show the topic now.
6695 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6697 * Added client searching by nickname hash into the IDENTIFY and
6698 WHOIS commands in the server as they were clearly missing from
6699 them. Affected file is silcd/command.c.
6701 * Fixed a bug in private message receiving in the client library.
6702 The remote ID was freed and it wasn't supposed, now it is
6705 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6707 * Minor fix to the channel payload; allocate the data area, as it
6708 needs to be of specific length.
6710 * If the key agreement port is zero then the operating
6711 system will define the bound port. Affected files are
6712 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
6714 * Added new function silc_channel_payload_decrypt into the file
6715 lib/silccore/silcchannel.[ch].
6717 * Moved the channel message etc, check from silc_packet_decrypt
6718 to applications. The library calls now a generic
6719 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
6720 when the packet is either normal or special. This was done to
6721 allow more wide range of checking that was not allowed when
6722 the code was in library. Now applications can do virtually any
6723 checks to the packet and return to the library the decision how
6724 the packet should be processed. Affected files are
6725 lib/silccore/silcpacket.[ch].
6727 Added silc_server_packet_decrypt_check to the server and
6728 silc_client_packet_decrypt_check to the client library.
6730 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
6731 to send with specified source and destination information.
6733 * Channel message delivery between routers was broken after the
6734 channel key distribution was fixed earlier. The channel key
6735 was used be to distributed to other routers as well which is not
6736 allowed by the protocol. Now this is fixed and channel keys
6737 really are cell specific and the channel message delivery between
6738 routers comply with the protocol specification.
6740 * Fixed various commands in server to check also the global list
6741 for the channel entry and not just the local list. The affected
6742 file silcd/command.c.
6744 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6746 * Added assert()s to buffer formatting and unformatting routines
6747 to assert (if --enable-debug) when error occurs. Affected
6748 file: lib/silcutil/silcbuffmt.c.
6750 * Changed to auto-reconnect to check whether the remote host is
6751 router and register the re-connect timeout if it is. It used
6752 to check that whether we are normal server, but router must do
6753 auto-reconnect with another router as well. Affected file
6756 * Removed the [<key len>] option from CMODE command as the cipher
6757 name decides the key length, nowadays. See the defined ciphers
6758 from the protocol specification.
6760 * Added [<hmac>] option to the CMODE command to define the HMAC
6761 for the channel. Added SILC_CMODE_HMAC channel mode.
6763 * Added [<hmac>] option for the JOIN command so that user can
6764 select which HMAC is used to compute the MACs of the channel
6767 * Added Hmac field to the Channel Message Payload. The integrity
6768 of plaintext channel messages are now protected by computing
6769 MAC of the message and attaching the MAC to the payload. The
6770 MAC is encrypted. Now, it is clear that this causes some
6771 overhead to the size of the packet but rationale for this is that
6772 now the receiver can verify whether the channel message decrypted
6773 correctly and also when private keys are set for the channel the
6774 receiver can decrypt the packet with several keys and check from
6775 the MAC which key decrypted the message correctly.
6777 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
6778 lib/silccrypt/silccipher.[ch].
6780 * Added silc_hash_len to return the digest length into the
6781 lib/silcrypt/silchash.[ch].
6783 * Rewrote parts of Silc Channel Payload interface in the
6784 lib/silccore/silcchannel.[ch]. The encode function now also
6785 encrypts the packet and parse function decrypts it.
6787 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6789 * Fixed a minor formatting bug in the SKE's key material processing.
6790 It actually might have processed the keys wrong way resulting
6793 * Redefined the mandatory HMAC algorithms and added new algorithms.
6794 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
6795 and hmac-md5 truncated to 96 bits. The mandatory is now
6796 hmac-sha1-96. Rest are optional (including the one that used
6797 to be mandatory). Rationale for this is that the truncated HMAC
6798 length is sufficient from security point of view and can actually
6799 make the attack against the HMAC harder. Also, the truncated
6800 HMAC causes less overhead to the packets. See the RFC2104 for
6803 * Added new [hmac] configuration section. The SKE used to use
6804 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
6805 is of course wrong. The official names that must be proposed in
6806 the SKE are the ones defined in the protocol specification
6807 (hmac-sha1-96 for example). The user can configure any hmac
6808 using any hash function configured in the [hash] section. At
6809 least, the mandatory must be configured.
6811 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
6813 * Added HMAC list to the SKE proposal list. It has now both
6814 hash algorithm list and HMAC list. This makes the protocol
6815 incompatible with previous versions. The SKE now seems to work
6816 the way it is supposed to work, for the first time actually.
6818 * Defined plain Hash algorithms to the protocol specification.
6821 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6823 * Implemented support for key agreement packets into the server.
6824 Added functions silc_server_key_agreement and
6825 silc_server_send_key_agreement. Other than these functions,
6826 server has nothing to do with this packet.
6828 * Added support for private message key packets into the server.
6829 Added functions silc_server_private_message_key and
6830 silc_server_send_private_message_key.
6834 * Changed the silc_[client|server]_protocol_ke_set_keys to be
6835 called in the protocol's final callback instead in the END
6836 protocol state. This makes a little more sense and in the same
6837 time in client we can use the same protocol routines for normal
6838 key exchange and to key agreement packet handling as well.
6840 * Added to both client's and server's KE protocol context the
6841 SilcSKEKeyMaterial pointer to save the key material. We will
6842 bring the key material to the protocol's final callback by doing
6843 this. The final callback must free the key material.
6845 * Added SKE's packet_send callback into client's KE protocol
6846 context so that the caller can choose what packet sending function
6847 is used. This way we can use different packet sending when
6848 doing normal SKE when doing key agreement packet handling (in
6849 the key agreement packet handling we do not want to encrypt
6852 * Implemented the responder side of the key agreement routines
6853 in the client. The client can now bind to specified port and
6854 accept incoming key negotiation. The key material is passed
6855 to the application after the protocol is over.
6857 * Implemented the processing of incoming Key Agreement packet
6858 in the client. Added function silc_client_key_agreement to
6861 * Implemented the intiator side of the key agreement routines
6862 in the client. The client can now initiate key agreement with
6863 another remote client. The key material is passed to the
6864 application after the protocol is over.
6866 * Created client_keyagr.c to include all the key agreement
6869 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
6870 SILC_TASK_CALLBACK except that it is not static.
6872 * Created client_notify.c and moved the Notify packet handling
6873 from the client.[ch] into that file.
6875 * Created client_prvmsg.c and moved all private message and
6876 private message key routines from the client.[ch] into that file.
6878 * Create client_channel.c and moved all channel message and
6879 channel private key routines from the client.[ch] into that file.
6881 * Changed silc_client_get_client_by_id_resolve to resolve with
6882 WHOIS command instead of IDENTIFY command, in the file
6883 lib/silclient/idlist.c.
6885 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6887 * Implemented the SKE's responder side to the Client library.
6889 * When FAILURE is received to the protocol do not trust it
6890 blindly. Register a timeout to wait whether the remote closes
6891 the connection as it should do it, only after that process the
6892 actual failure. This was changed to both client and server.
6894 * Added client_internal.h to include some of the structures
6895 there instead of client.h in lib/silcclient/.
6897 * Added function silc_task_unregister_by_callback to unregister
6898 timeouts by the callback function.
6900 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6902 * Some "Incomplete WHOIS info" errors has been appearing on the
6903 log files. Took away the entry->userinfo check from WHOIS
6904 reply sending. The entry->userinfo is now " " if client did not
6905 provide one. I thought this was fixed earlier but something
6906 is wrong still. Let's see if the error still appears.
6908 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6910 * Fixed a minor bug in the login when the channel key is
6911 re-generated in the server. It used to generate the key in
6912 wrong order and thus caused problems in the channel traffic.
6914 * Fixed a minor bug in channel key distsribution after
6915 KICK command. The key was not sent to the router even though
6918 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6920 * Added silc_ske_process_key_material_data as generic routine
6921 to process any key material as the SILC protocol dictates. The
6922 function is used by the actual SKE library but can be used by
6923 applications as well. This relates to the private message keys
6924 and the channel private keys since they must be processed the
6925 same way the normal SILC session keys. The protocol dictates
6926 this. Affected files: lib/silcske/silcske.[ch].
6928 Added also silc_ske_free_key_material to free the
6929 SilcSKEKeyMaterial structure.
6931 * Defined silc_cipher_set_key function to set the key for
6932 cipher without using the object's method function. The affected
6933 files: lib/silccrypt/silccipher.[ch].
6935 * Implemented silc silc_client_add_private_message_key,
6936 silc_client_add_private_message_key_ske,
6937 silc_client_del_private_message_key,
6938 silc_client_list_private_message_keys and
6939 silc_client_free_private_message_keys functions in the
6942 Added functions silc_client_send_private_message_key to send
6943 the Private Message Key payload and silc_client_private_message_key
6944 to handle incoming Private Message Key payload.
6946 * Added Cipher field to the Private Message Key payload to set
6947 the cipher to be used. If ignored, the default cipher defined
6948 in the SILC protocol (aes-256-cbc) is used.
6950 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6952 * Removed lib/silcclient/ops.h file.
6954 Redefined parts of the SILC Client Library API. Created new
6955 file silcapi.h that deprecates the ops.h file and defines the
6956 published Client Library API. Defined also private message key
6957 API and channel private key API into the file.
6959 This is the file that the application must include from the
6960 SILC Client Library. Other files need not be included by
6961 the application anymore.
6963 * Added new key_agreement client operation callback and also
6964 defined the Key Agreement library API for the application.
6966 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6968 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
6969 is used by clients to request key negotiation between another
6970 client in the SILC network. If the negotiation is started it
6971 is performed using the SKE protocol. The result of the
6972 negotiation, the secret key material, can be used for example
6973 as private message key.
6975 Implemented the Key Agreement payload into the files
6976 lib/silccore/silauth.[ch].
6978 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6980 * Redefined ciphers for the SILC protocol. Added some new ciphers
6981 and defined the key lengths for the algorithms. Changed the
6982 code accordingly. The default key length is now 256 bits.
6984 * Fixed SKE key distribution function silc_ske_process_key_material
6985 when the key length is more than 128 bits. The default key
6986 length in SILC is now 256 bits.
6988 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
6989 to indicate unsupported algorithm.
6991 * Renamed rijndael.c to aes.c and all functions as well.
6993 * Fixed a long standing channel key setting bug in client library.
6994 Weird that it has never surfaced before.
6996 * Fixed bug in channel deletion. If the entire channel is removed
6997 then it must also delete the references of the channel entry
6998 from the client's channel list as the client's channel entry and
6999 the channel's client entry share same memory.
7001 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7003 * Implemented CONNECT and SHUTDOWN commands in the client.
7005 * Implemented CLOSE command to the client.
7007 * Added the function silc_idlist_find_server_by_name into the
7008 files silcd/idlist.[ch].
7010 Added the function silc_idlist_find_server_by_conn into the
7011 files silcd/idlist.[ch].
7013 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7015 * DIE command was renamed to SHUTDOWN. Updated the both code
7018 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
7019 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
7021 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
7024 * Added function silc_server_create_connection function to create
7025 connection to remote router. My server implementation actually
7026 does not allow router to connect to normal server (it expects
7027 that normal server always initiates the connection to the router)
7028 so the CONNECT command is only good for connecting to another
7031 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7033 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
7034 or some other client was kicked from the channel.
7036 Implemented the handling of the notify type to both client
7039 Implemented silc_server_send_notify_kicked to send the KICKED
7040 notify. It is used to send it to the server's primary router.
7042 * Implemented the KICK command into server and client.
7044 * Added `query' argument to the silc_idlist_get_client function
7045 to indicate whether to query the client from server or not if
7048 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
7049 to indicate that the client is not channel founder.
7053 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7055 * Removed the rng context from SilcPacketContext structure and
7056 changed that the packet routine uses the Global RNG API.
7058 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7060 * Added support for quit message that client can "leave" on the
7061 channel when it quits the SILC. It is ditributed inside the
7062 SILC_NOTIFY_TYPE_SIGNOFF notify type.
7064 Added silc_server_free_client_data that will take the
7065 signoff message as argument.
7067 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
7069 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7071 * Updated parts of the protocol specification to keep it up
7074 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7076 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
7077 payloads in one packet.
7079 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
7080 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
7081 use now the new List flag.
7083 * Also deprecated the following packet types: REPLACE_ID,
7084 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
7086 * Added list support for Notify packet in server.
7088 * Added silc_server_send_notify_channel_change to send the
7089 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
7090 the silc_server_send_replace_id.
7092 * Added silc_server_send_notify_nick_change to send the
7093 NICK_CHANGE notify type. Deprecates the function
7094 silc_server_send_replace_id.
7096 * Added silc_server_send_notify_join to send the JOIN notify type.
7097 Deprecates the function silc_server_send_new_channel_user.
7099 * Added silc_server_send_notify_leave to send LEAVE notify type.
7100 Deprecates the function silc_server_send_remove_channel_user.
7102 * Added silc_server_send_notify_cmode and
7103 silc_server_send_notify_cumode to send CMODE and CUMODE notify
7104 types. Deprecates the silc_server_send_set_mode function.
7106 * Added SERVER_SIGNOFF notify type to indicate that server has
7107 quit. This means that all clients on the channel from that
7108 server will drop. This can be also used when netsplit happens.
7110 Deprecated REMOVE_ID packet type since it is not needed anymore
7113 Added silc_server_send_notify_server_signoff to send the
7114 SERVER_SIGNOFF notify type. Deprecates the function
7115 silc_server_send_remove_id.
7117 Added also silc_server_send_notify_signoff to send the
7118 SIGNOFF notify type.
7120 * Employed the PKCS #1. It is the mandatory way to do RSA in the
7121 SILC protocol from this day on. Changed the protocol
7122 specification as well.
7124 * Added silc_server_send_notify_topic_set to send TOPIC_SET
7125 notify type. It is used between routers to notify about
7126 topic changes on a channel.
7128 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
7131 * Partly updated the protocol specification to comply with the
7132 changes now made. It is still though a bit outdated.
7134 * The JOIN notify type now takes one extra argument <Channel ID>.
7135 The packet used to be destined to the channel but now the
7136 JOIN type may be sent as list thus it is impossible to
7137 destine it to any specific channel. By adding this argument
7138 it is again possible.
7140 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7142 * Added CREDITS file. The CHANGES and CREDITS file will appear
7143 in the distribution as well.
7145 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7147 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
7148 types in the server's silcd/packet_receive.c.
7150 * Implemented CMODE and CUMODE to work in router environment.
7152 * Fixed minor encoding and decoding buglet from the
7153 lib/silccore/silcmode.c.
7155 * Fixed buffer overflow from lib/silcclient/command.c in USERS
7158 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
7160 * Changed all SilcConfigServer* and silc_config_server* to
7161 SilcServerConfig* and silc_server_config*, respectively.
7164 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7166 * Associated the ID (client or server ID) to the Authentication
7167 Payload to avoid any possibility of forging. Updated the
7168 protocol specification and the code accordingly.
7170 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7172 * The RSA key length is now save to the RsaKey context in the
7173 key generation process in lib/silccrypt/rsa.c. The key length
7174 is now used to figure out the maximum size of the block allowed
7175 to be encrypted/signed.
7177 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
7178 is equivalent to the silc_mp_mp2bin but does not allocate any
7181 * Changed silc_mp_mp2bin API to take length argument. If it is
7182 non-zero then the buffer is allocated that large. If zero, then
7183 the size is approximated using silc_mp_sizeinbase, which however
7186 * Created Global RNG API which is global RNG that application can
7187 initialize. After initializing, any routine anywhere in the
7188 code (including library) can use RNG without allocating a new
7189 RNG object. This was done to allow this sort of use of the
7190 RNG in code that has no chance to allocate RNG object. All
7191 applications currently allocate this and many routines in the
7192 library use this. Affected file lib/silccrypt/silcrng.[ch].
7194 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
7195 it to use the Global RNG API.
7197 * Defined Authentication Payload into protocol specification that
7198 is used during SILC session to authenticate entities. It is
7199 used for example by client to authenticate itself to the server
7200 to obtain server operator privileges.
7202 Implemented this payload into the lib/silccore/silcauth.[ch].
7203 Implemented also routines for public key based authentication
7204 as the new protocol specification dictates.
7206 Moved definitions of different authentication methods from
7207 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
7209 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
7210 silc_pkcs_verify and silc_pkcs_sign_with_hash and
7211 silc_pkcs_verify_with_hash functions into the file
7212 lib/silccrypt/silcpkcs.[ch].
7214 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7216 * The client entry's userinfo pointer must be always valid.
7217 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
7218 will fail since it requires the userinfo. Now, the userinfo
7219 is allocated as "" if actual userinfo does not exist. Actually,
7220 it must exist and it is totally Ok to drop client connections
7221 that does not announce the userinfo. However, we will make
7222 this workaround for now.
7224 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
7225 to return the remote port by socket.
7227 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7229 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
7230 SILC_SERVER_PENDING_EXEC and added an new macro
7231 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
7232 data or when error occurs while processing the pending command.
7234 Added new argument `destructor' into silc_server_command_pending
7235 and to the SilcServerCommandPending object. This destructor is
7236 now called after calling the pending callback or if error occurs
7237 immediately. If error occurs the actual pending callback won't
7238 be called at all - only the destructor. The destructor may be
7239 NULL if destructor is not needed.
7241 All this applies for client library code as well. Similar
7242 changes were made there as well for the pending commands.
7244 In the client, the application must now allocate the
7245 SilcClientCommandContext with the silc_client_command_alloc
7248 * Added reference counter to the SilcServerCommandContext. Added
7249 function silc_server_command_alloc and silc_server_command_dup
7252 Same type of functions added to the client library for the same
7255 * Removed the cmd_ident from IDListData away since it is now
7256 global for all connections. It is the command identifier used
7257 in command sending and with pending commands. The affected file
7260 * Added reference counter to the SilcSocketConnection objecet to
7261 indicate the usage count of the object. The object won't be
7262 freed untill the reference counter hits zero. Currently only
7263 server uses this, and client ignores it. The client must be
7264 set to use this too later. The affected files are
7265 lib/silccore/silcsockconn.[ch]. Added also the function
7266 silc_socket_dup to increase the reference counter.
7268 This was mainly added because it is possible that the socket
7269 is removed underneath of pending command or other async
7270 operation. Now it won't be free'd and proper DISCONNECTING
7271 flags, etc. can be set to avoid sending data to connection that
7272 is not valid anymore.
7274 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
7275 the connection. After that it sets SILC_SET_DISCONNECTED.
7276 It is, however, possible that the socket data is not still freed.
7277 The silc_server_packet_process now checks that data is not
7278 read or written to connection that is DISCONNECTED. The socket
7279 get's freed when the reference counter hits zero.
7281 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7283 * Changed the client operation API: channel_message operation's
7284 `sender' is now the client entry of the sender, not the nickname
7285 and the `channel' is the channel entry, not the channel name.
7287 In the private_message operation the `sender' is now also the
7288 client entry of the sender not the nickname.
7290 Affected file is lib/silcclient/ops.h and all applications
7291 using the client operations.
7293 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7295 * Moved the calling of ops->connect() from connect_to_server_final
7296 into receive_new_id functin since that is the point when the
7297 client is actually allowed to send traffic to network. The
7298 affected file is lib/silcclient/client.c.
7300 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7302 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
7303 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
7304 (if needs broadcasting) instead of broadcasting the packets one
7305 by one which would make a burst in the network traffic.
7307 * Added `broadcast' argument to the functions in silcd/server.[ch]
7308 silc_server_create_new_channel[_with_id] to indicate whether
7309 to send New Channel packet to primary router.
7311 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7313 * Added new function into the silcd/server.[ch] files:
7314 silc_server_create_new_channel_with_id to create new channel with
7315 already existing Channel ID.
7317 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
7318 lib/silccore/silcpacket.h. This packet is used t send list of
7319 Set Mode payloads inside one packet. Server uses this to set
7320 the modes for the channels and clients on those channels, that it
7321 announced to the router when it connected to it. The protocol
7322 specification has been updated accordingly.
7324 * The silc_server_new_channel did not handle the packet coming
7325 from normal server as it normally does not send that. However,
7326 when it announces its channels it does send it. Implemented
7327 the support for that.
7329 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
7330 into the file lib/silccore/id.h.
7332 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7334 * Fixed memory leaks in the functions silc_idlist_del_client,
7335 silc_idlist_del_channel and silc_idlist_del_server in the file
7336 silcd/idlist.c. All of those leaked like a sieve.
7338 * Fixed some small memory leaks in the client's function
7339 silc_client_notify_by_server.
7341 * Added functions into silcd/server.c: silc_server_announce_clients,
7342 silc_server_announce_channels and silc_server_announce_server.
7343 These functions are used by normal and router server to announce
7344 to its primary router about clients, channels and servers (when
7345 router) that we own. This is done after we've connected to the
7348 These functions effectively implements the following packet types:
7349 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
7350 and SILC_PACKET_NEW_ID_LIST.
7352 * Added new functions into the silcd/packet_receive.[ch]:
7353 silc_server_new_id_list, silc_server_new_channel_list and
7354 silc_server_new_channel_user_list to handle the incoming
7355 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
7357 * Added support of changing Channel ID in the function
7358 silc_server_replace_id. If the server that announces a channel
7359 to the router already exists in the router (with same name but
7360 with different Channel ID), router is responsible to send
7361 Replace ID packet to the server and force the server to change
7362 the Channel ID to the one router has.
7364 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
7365 client that the Channel ID has been changed by the router. The
7366 normal server sends this to the client. Client must start using
7367 the new Channel ID as the channel's ID.
7369 Implemented handling of this new type into lib/silcclient/client.c
7370 into the function silc_client_notify_by_server.
7372 * Added new function silc_idlist_replace_channel_id into the files
7373 silcd/idlist.[ch] to replace the Channel ID.
7375 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7377 * Call silc_server_command_identify_check always when processing
7378 the IDENTIFY command in silcd/command.c
7380 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7382 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
7383 send keepalive packets. The packet can be sent by clients,
7384 servers and routers.
7386 Added function silc_socket_set_heartbeat into the file
7387 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
7388 If not set, the heartbeat is not performed. The actual
7389 heartbeat is implemented in the low level socket connection
7390 library. However, application is responsible of actually
7393 Added silc_server_send_heartbeat to send the actual heartbeat
7394 packet into silcd/packet_send.[ch]. Server now performs
7395 keepalive with all connections.
7397 * Added silc_task_get_first function into lib/silcutil/silctask.c
7398 to return the timeout task with shortest timeout. There was a bug
7399 in task unregistration that caused problems. TODO has been
7400 updated to include that task system must be rewritten.
7402 * The client library will now resolve the client information when
7403 receiving JOIN notify from server for client that we know but
7404 have incomplete information.
7406 * Rewrote parts of silc_server_remove_from_channels and
7407 silc_server_remove_from_one_channel as they did not remove the
7408 channel in some circumstances even though they should've.
7410 * Encryption problem encountered in server:
7412 The LEAVE command used to send the Channel Key packet to the
7413 router immediately after generating it. However, the code
7414 had earlier sent Remove Channel user packet but not immediately,
7415 ie. it was put to queue. The order of packets in the router
7416 was that Channel Key packet was first and Remove Channel User
7417 packet was second, even though they were encrypted in the
7418 reverse order. For this reason, MAC check failed. Now, this
7419 is fixed by not sending the Channel Key packet immediately but
7420 putting it to queue. However, this is more fundamental problem:
7421 packets that are in queue should actually not be encrypted
7422 because packets that are sent immediately gets encrypted
7423 actually with wrong IV (and thus MAC check fails). So, packets
7424 that are in queue should be encrypted when they are sent to
7425 the wire and not when they put to the queue.
7427 However, the problem is that the current system has not been
7428 designed to work that way. Instead, the packet is encrypted
7429 as soon as possible and left to the queue. The queue is then
7430 just purged into wire. There won't be any fixes for this
7431 any time soon. So, the current semantic for packet sending
7434 o If you send packet to remote host and do not force the send
7435 (the packet will be in queue) then all subsequent packets to the
7436 same remote host must also be put to the queue. Only after the
7437 queue has been purged is it safe again to force the packet
7440 o If you send all packets immediately then it safe to send
7441 any of subsequent packets through the queue, however, after
7442 the first packet is put to queue then any subsequent packets
7443 must also be put to the queue.
7445 Follow these rules and everything works fine.
7447 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7449 * Added new function silc_server_remove_clients_by_server to
7450 remove all client entries from ID list when the server connection
7451 is lost. In this case it is also important to invalidate all
7452 client entires as they hold the invalid server entry. This
7453 fixes fatal bug when server has lost connection and will reconnect
7456 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7458 * Made some sanity checks to silc_server_daemonise like to check
7459 whether the requested user and group actually exists.
7461 * Added sanity check to SKE's silc_ske_responder_finish to check
7462 that the public and private key actually is valid.
7464 * Invalidate the client's nickname when receiving Replace ID
7465 packet and the Client ID is being replaced. This means that the
7466 server will query the nickname if someone needs it (client)
7469 * Sort the ID Cache in client library when the ID Cache data
7470 has changed (needs sorting).
7472 * Do not allow for SILC client to create several connections to
7473 several servers. The client does not support windows right now
7474 and generating multiple connections causes weird behaviour.
7476 Irssi-silc client does support windows and can handle several
7477 connections without problems, see: www.irssi.org and SILC plugin.
7479 * Fixed some places where client was added to the IDList. The
7480 rule of thumb is following (in order to get everything right):
7481 If the client is directly connected local client then the
7482 `connection' argument must be set and `router' argument must be
7483 NULL to silc_idlist_add_client function. If the client is not
7484 directly connected client then the `router' argument must
7485 bet set and the `connection' argument must be NULL to the
7486 silc_idlist_add_client function.
7488 * The funtion silc_server_packet_send_local_channel actually did
7489 not check whether the client was locally connected or not. It
7490 does that now. Fixed a bug related to LEAVE command.
7492 * Fixed Remove Channel User payload parsing bug in server's
7493 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
7495 * The server's silc_server_save_channel_key now checks also the
7496 global ID list for the channel as it might not be in the local
7497 list. Fixed a bug related to LEAVE command.
7499 * Is this the end of the [<unknown>] buglet that has been lurking
7500 around for a long time? A little for loop fix in server's
7501 silc_server_command_whois_parse that is used by both IDENTIFY
7502 and WHOIS command. At least, this was a clear bug and a cause
7503 of one type of [<unknown>] buglet.
7505 * WHOIS and IDENTIFY commands call the function
7506 silc_server_command_[whois/identify]_check function even if
7507 we are not router server.
7509 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7511 * Added --with-gmp configuration option. If set the GMP
7512 is always compiled in the SILC source tree. If not set then
7513 it is checked whether the system has the GMP3 installed. If
7514 it has then the GMP won't be compiled (the system's headers
7515 and library is used), if it doesn't have it then the GMP is
7516 compiled in the SILC source tree.
7518 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7520 * Changed RSA private exponent generation to what PKCS #1
7521 suggests. We try to find the smallest possible d by doing
7522 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
7523 not security fix but optimization.
7525 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7527 * Added new config entry [Identity] to fork the server and run
7528 it as specific user and group. A patch from Bostik.
7530 * Imported Dotconf configuration library into lib/dotconf.
7531 This will be used to create the SILC configuration files later.
7532 It will appear in the distsribution after this commit.
7534 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7536 * A big code auditing weekend happening. Auditing code for
7537 obvious mistakes, bugs and errors. Also, removing any code
7540 Removed files for being obsolete:
7542 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
7543 inline in the file lib/silcutil/silcbuffer.h)
7545 o lib/silcutil/silcbufutil.c (the header has inline versions)
7547 Changed code to fix possible error conditions:
7549 o The buffer formatting routines now check that the destination
7550 buffer really has enough space to add the data. This applies for
7551 both buffer formatting and unformatting
7552 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
7553 unformatting was changed to accomodate following rules:
7554 XXX_*STRING_ALLOC will allocate space for the data into the pointer
7555 sent to the function while XXX_*STRING will not allocate or copy
7556 the data into the buffer. Instead it sets the pointer from the
7557 buffer into the pointer sent as argument (XXX_*STRING used to
7558 require that the pointer must be allocated already). This change
7559 makes this whole thing a bit more consistent and more optimized
7560 (note that the data returned in the unformatting with XXX_*STRING
7561 must not be freed now). The routines return now -1 on error.
7563 o Tried to find all code that use buffer_format and buffer_unformat
7564 and added return value checking to prevent formatting and
7565 especially unformatting errors and possible subsequent fatal
7568 o Changed ske->x and ske->KEY to mallocated pointers in
7569 lib/silcske/silcske.h. Fixed possible data and memory leak.
7571 o Added return value checking to all *_parse* functions. Fixed
7572 many memory leaks as well.
7574 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
7575 so that buffer overflows would not happen. All code now also
7576 checks the return value as it can fail.
7578 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7580 * Added reconnection support to server if the normal server looses
7581 its connection to the router (for example if router is rebooted).
7582 The server performs normal reconnection strategy implemented
7583 to the server. Affected file silcd/server.c.
7585 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7587 * Added new packet type SILC_PACKET_SET_MODE that is used to
7588 distribute the information about changed modes (for clients,
7589 channels and clients channel modes) to all routers in the
7590 network. Updated the protocol specification accordingly.
7592 Added functions into silcd/packet_send.c and
7593 silcd/packet_receive.c: silc_server_send_set_mode,
7594 silc_server_set_mode.
7596 Added new files silcmode.[ch] into lib/silccore that implements
7597 the encoding and decoding of Set Mode Payload. Added new type
7598 SilcSetModePayload. Moved the definitions of different modes
7599 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
7601 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7603 * Oops, a little mistake in server's connection authentication
7604 protocol. The protocol is not ended with FAILURE but with
7605 SUCCESS if the authentication is Ok. :) Affected file is
7608 * Implemented NICK_CHANGE notify handling in server in the file
7609 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
7610 the local clients on the channel. After the changing nickname
7611 in router environment snhould work and the [<unknown>] nickname
7612 should appear no more.
7614 The silc_server_replace_id function that receives the Replace ID
7615 payload now sends the NICK_CHANGE notify type also in the file
7616 silcd/packet_receive.c
7618 * Changed WHOIS and IDENTIFY command to support the maximum amount
7619 of arguments defined in protocol specs (3328 arguments). This
7620 fixed a bug that caused problems when there were more than three
7623 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7625 * Added extra parameter, command identifier, to the
7626 silc_client_send_command so that explicit command identifier
7629 Changed that ID list routines uses specific command identifier
7630 when sending WHOIS/IDENTIFY requests to the server so that they
7631 can be identified when the reply comes back.
7633 Affected files lib/silcclient/command.[ch],
7634 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
7636 * Added `sender' argument to silc_server_packet_send_to_channel
7637 to indicaet the sender who originally sent the packet to us
7638 that we are now re-sending. Ignored if NULL. Affected file
7639 silcd/packet_send.[ch].
7641 * Added some server statistics support in silcd/server_internal.h
7642 SilcServerStatistics structure and around the server code. Also
7643 send some nice statistics information when client is connecting
7646 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7648 * Fixed channel ID decoding in server's JOIN command reply in
7649 silcd/command_reply.c
7651 * Fixed braodcasting of replace ID payload to not to send it if
7652 we are standalone server in silcd/packet_receive.c.
7654 * Fixed all channel message sending routines to not to send
7655 packets to clients that has router set, since they are routed
7656 separately in the same function earlier. Affects file
7657 silcd/packet_send.c and all channel packet sending functions.
7659 * In USERS reply, res_argv[i] are not allocated, the table
7660 is allocated. Thus changed that free the table, not its
7663 * In server's whois_check and identify_check if the client is
7664 locally connected do not send any WHOIS commands - they are not
7667 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7669 * Fixed some minor bugs in client when sending WHOIS command. The
7670 arguments was in wrong order.
7672 * Removed statis function add_to_channel from server in
7673 silcd/command.c that was previously used with the joining but
7676 * Tested USERS command in router environment successfully with two
7677 routers, two servers and two clients.
7679 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7681 * Reorganized the USERS command and command reply in client library
7682 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
7683 When the command is given by user we register a pending command
7684 callback that will reprocess the command after the reply has been
7685 received from the server. When reprocessing the packet we then
7686 display the information. Thus, the USERS information is displayed
7687 now in the command callback instead of in the command reply
7688 callback. The processing of the command is same as previously
7689 when server has sent the command reply in the JOINing process.
7691 * Added to USERS command in silcd/command_reply.c to join the client,
7692 we didn't use to know about, to the channel after we've created
7693 a client entry for it. Also, for clienet we did know already still
7694 check whether it is on the channel or not and add it if not.
7696 * Removed silc_server_command_join_notify as the function and its
7699 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7701 * Changed the client's pending command handling to the same as the
7702 server's pending command handling. It is also now possible to
7703 execute command reply functions from other command reply
7704 function as the function callbacks for commands and command
7705 replies are one and same. The pending commands are not static
7706 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
7707 in client connection context. Thus, pending commands are server
7708 connection specific as it is convenient.
7710 Changed the function silc_client_command_pending and
7711 silc_client_command_pending_del and added new function
7712 silc_client_command_pending_check. Removed the
7713 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
7716 * Added cmd_ident, current command identifier, to the client
7717 connection context in lib/silcclient/client.h to keep track on
7718 command identifiers used in command sending. Client's command reply
7719 function handling now supports the mandatory command identifiers.
7721 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
7722 funtions in client to fully support pending command callbacks.
7724 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
7725 as one of the arguments to the application in the command reply
7728 * NOTE: The FORWARDED flag is depracated. It used to be depracated
7729 before first releasing SILC but came back. Now it is removed again
7730 and should come back nomore. The FORWARDED flag was used only
7731 by the JOINing procedure by forwarding the command packet to router.
7732 Now, the JOINing procedure has been changed to more generic (due
7733 to various router environment issues) and FORWARDED is not needed
7734 anymore for anything. The protocol specification is yet to be
7737 Now, removed silc_server_packet_forward from server and the flag
7738 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
7740 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7742 * Renamed NAMES command to USERS command. The NAMES was named that
7743 due to historical reasons. Now it is renamed. Also, rewrote
7744 parts of the USERS command. The nickname list is not sent anymore
7745 by the server. Only Client ID and mode lists are sent in the USERS
7746 command. Changed this also to the protocol specification.
7748 The client now resolves the names and stuff after it receives
7749 the USERS list from the server when joining to the channel.
7751 * WHOIS and IDENTIFY commands has been changed to support multiple
7752 Client ID's per command. One can now search for multiple users
7753 in the network by sending only one WHOIS or IDENTIFY command.
7754 Changed the code and the protocol specifications.
7756 * Removed silc_server_command_identify_parse and changed that IDENTIFY
7757 uses silc_server_command_whois_parse to parse the request. */
7759 * If normal server, do not parse the WHOIS and IDENTIFY requests
7760 before sending it to the router. Saves some time.
7762 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7764 * Fixed JOIN command on client library. Wrong number of arguments
7765 used to crash the client.
7767 * Added silc_server_channel_has_global function to check whether
7768 channel has global users or not.
7770 * Added silc_server_channel_has_local function to check whether channel
7771 has locally connected clients on the channel.
7773 * The silc_server_remove_from_one_channel now checks whether the
7774 channel has global users or not after given client was removed from
7775 the channel. It also checks whether the channel has local clients
7776 on the channel anymore. If it does not have then the channel entry
7777 is removed as it is not needed anymore.
7779 * The silc_server_notify now checks on JOIN notify whether the joining
7780 client is one of locally connected or global. If it is global then
7781 the channel has now global users on the channel and that is marked
7782 to the channel entry. Also, it now saves the global client to
7783 global list who is joining and JOINs it to the channel. This is
7784 for normal server, that is.
7786 Changed silc_server_send_notify_on_channel,
7787 silc_server_packet_relay_to_channel and
7788 silc_server_packet_send_to_channel check if we are normal server
7789 and client has router set (ie. global client) do not send the
7790 message to that client, as it is already routed to our router.
7792 * Implemented LEAVE notify type handling in silc_server_notify
7795 * Tested LEAVE command in router environment successfully. Tested
7796 with two routers, two servers and two clients.
7800 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
7802 * Implemented SIGNOFF notify type handling in silc_server_notify
7805 * silc_server_remove_id now removes the client entry from all channels
7806 it has joined and thusly sends SIGNOFF notify type.
7808 * Rewrote the NAMES list generation in server by removing two excess
7809 loops. The lists are created now inside one loop.
7811 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7813 * silc_server_remove_channel_user checks now also global list
7814 for channel and client.
7816 * silc_server_new_channel_user checks now both local and global
7817 list for channel and client. Fixed a bug in client id decoding.
7818 Used to decode wrong buffer.
7820 * silc_server_channel_message checks now both local and global
7821 list for channel entry.
7823 * Tested channel joining (hence JOIN) in router environment
7824 successfully. Tested with two routers, two servers and two
7827 * Tested channel message sending in router environment successfully.
7829 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7831 * Added silc_server_save_channel_key into server.[ch] to save the
7832 received channel key in Channel Key payload processing. It is
7833 also used in JOIN command reply handling.
7835 Equivalent function silc_client_save_channel_key added into
7836 client.[ch] into client library.
7838 * Changed JOIN command reply to send information whether the channel
7839 was created or not (is existing already) and the channel key
7840 payload. Changed protocol specs accordingly.
7842 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
7843 the request was sent by ID and not by nickname. Crashed on
7846 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7848 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
7849 now correctly save the received data.
7851 * silc_server_free_sock_user_data now notifies routers in the
7852 network about entities leaving the network.
7854 At the same time implemented functions silc_server_remove_id
7855 and silc_server_send_remove_id to receive and send REMOVE_ID
7856 packets. The packet is used to notify routers in the network
7857 about leaving entities. The ID removed will become invalid in
7860 * Added function silc_idlist_del_server into server. Removes and
7861 free's server entry from ID list.
7863 * silc_server_private_message function now checks, if we are router,
7864 that the destination ID really is valid ID, naturally.
7866 * In router when NEW_ID packet is received (for new client) the
7867 hash of the Client ID is saved in the ID Cache but the
7868 client->nickname is set to NULL, instead of putting the hash
7871 IDENTIFY command now also checks that client->nickname must be
7872 valid. If it is not if will request the data from the server who
7873 owns the client. Added new function
7874 silc_server_command_identify_check.
7876 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
7877 to set the command to already allocated Command Payload.
7879 * Tested private message sending in router environment with two
7880 routers, two servers and two clients. Fixed minor bugs and now
7883 * Fixed segfault from client's NAMES command. Used to crash if
7886 * Forwarded packets must not be routed even if it is not destined
7887 to the receiver. Changed server code comply with this.
7889 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7891 * Added `require_reverse_mapping' boolean value to ServerParams
7892 structure. If TRUE (not default) the server will require that
7893 the connecting host has fully qualified domain name.
7895 If the reverse mapping is not required and hostname could not be
7896 found the IP address is used as hostname.
7898 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7900 * Implemented version string checking to both client and server.
7901 The check is incomplete currently due to the abnormal version
7902 strings used in development version of SILC.
7904 * Changed all command functions in server to use the new
7907 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7909 * Changed char *data to unsigned char *data in ID Cache system to
7910 support binary data as ID Cache data. Changed code to support
7911 binary data in lib/silccore/idcache.c.
7913 * Renamed silc_server_packet_relay_command_reply to
7914 silc_server_command_reply as it is normal packet receiving
7915 function. Rewrote the function to accept command replys for
7916 servers and not only for clients.
7918 * Mark remote router always as registered server if we are connecting
7919 to it. Otherwise, commands sent by the router to us are ignored.
7921 * All ID List find routines now returns the ID Cache Entry pointer
7922 as well if requested.
7924 * WHOIS command works now in router environment, tested with two
7925 routers, two servers and two clients.
7927 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
7928 in router environment (as it is almost equivalent to WHOIS) but
7929 hasn't been tested thoroughly. Added new functions:
7931 silc_server_command_identify_parse
7932 silc_server_command_identify_send_reply
7933 silc_server_command_identify_from_client
7934 silc_server_command_identify_from_server
7936 * Disabled route cache adding because adding two different ID's with
7937 same IP replaces the old cache entry thus giving wrong route.
7938 The entry->router->connection is always the fastest route anyway
7939 so route cache may not be needed. Of course, new routes maybe
7940 established after receiving the ID when the entry->router->connection
7941 might not be anymore the most optimal.
7943 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7945 * Add route cache for received ID for fast routing.
7947 * Added silc_server_packet_route to route received packet on router
7948 that is not destined to us.
7950 * Renamed silc_server_get_route to silc_server_route_get.
7952 * Added id_string and id_string_len fields into SilcServer to
7953 include encoded ServerID for fast comparing without excess
7954 encoding of the ID's.
7956 * Cleaned up WHOIS command on server side. Added following static
7959 silc_server_command_whois_parse
7960 silc_server_command_whois_check
7961 silc_server_command_whois_send_reply
7962 silc_server_command_whois_from_client
7963 silc_server_command_whois_from_server
7965 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
7966 arguments in command replies. All command functions should be
7967 updated to use this macro.
7969 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7971 * Minor typo fixes on command reply handling on server.
7973 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7975 * Added silc_server_command_add_to_channel internal routine to add
7976 the client to the channel after router has created the channel and
7977 sent command reply to the server.
7979 * Added generic silc_server_send_command to send any command from
7982 * Use static buffer with ID rendering instead of duplicating data.
7984 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7986 * Fixed a channel user mode bug when joining to a channel server gave
7987 everybody channel founder rights, oops.
7989 * We mark ourselves as the router of the incoming server connection
7990 if we are router ourselves. This way we can check in some packet
7991 sending functions whether it is locally connected server. For
7992 incoming router connections we put NULL.
7994 * For router sending packets locally means now always sending the
7995 packet cell wide; to local clients and local servers. For normal
7996 server sending packet locally means sending it to only local
7999 * Fixed the JOIN command to really work in router environment. If the
8000 channel is created it is always created by the router. Router is
8001 also responsible of making the initial joining to the channel,
8002 sending JOIN notify to the sending server and distributing
8003 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
8004 does not exist server doesn't do anything else but forward the
8005 command to the router which performs everything.
8007 * Added silc_server_send_channel_key function to send the Channel Key
8010 * Added silc_server_create_channel_key to create new channel key. The
8011 channel key is now re-generated everytime someone joins or leaves
8012 a channel, as protocol dictates. Note: channel->key_len is the
8015 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8017 * Splitted server.[ch] finally. Created now packet_send.[ch] and
8018 packet_receive.[ch] to separate packet sending and receiving
8019 routines. The server.[ch] now includes everything else including
8020 actual packet processing (writing and reading data) and other
8023 Renamed silc_server_private_message_send_internal to
8024 silc_server_send_private_message. The routine is still though
8025 used only to relay private messages as server does not send
8026 private messages itself.
8028 Renamed silc_server_new_channel to silc_server_create_new_channel
8029 and added new function sicl_server_new_channel that handles the
8030 incoming New Channel packet. Added also new sending function
8031 silc_server_send_new_channel to send New Channel Payload.
8033 * Added new function silc_server_notify to process incoming notify
8034 packet to the server/router. Server may then relay the notify
8035 to clients if needed.
8037 * Added new function silc_server_new_channel_user to process incoming
8038 New Channel User packet. Router will redistribute the packet and
8039 send JOIN notify to its local clients and locally connected servers
8040 if needed. Normal server will send JOIN notify to its local client
8041 on same channel when received this packet. Added also corresponding
8042 sending function silc_server_send_new_channel_user to sent the
8045 * Added boolean route argument to send_notif_to_channel and
8046 packet_send_to_channel functions to attempt to route the packet
8047 if it is TRUE and send only locally if it is FALSE.
8049 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8051 * silc_server_replace_id now broadcasts the received replace ID
8052 packet if it is not broadcast packet already. The router must
8053 broadcast to inform other routers about changed ID.
8055 * Added backpointer to server's router into SilcServer context in
8056 silcd/server_internal.h.
8058 * Fixed silc_server_packet_broadcast to send correct broadcast
8061 * The channel key is now distributed to the local client as soon
8062 as it is received from the router (in router environment) so that
8063 no other packet may be sent for the channel until client has
8066 * silc_server_remove_channel_user now broadcasts the received
8067 Remove Channel User packet if it is not broadcast packet already.
8068 The router must broadcast to inform other routers about removed
8071 * Added users field into SilcPacketContext that is a reference count
8072 of the context. One can increase the reference count by calling
8073 silc_packet_context_dup which is now changed to just increase the
8074 reference count instead of duplicating the data. The reference
8075 count is decresed by calling silc_packet_context_free that will
8076 free the data after the reference count hits zero.
8078 For now on the packet context and everything allocated into it
8079 (including the raw packet from network) must be freed by calling
8080 the new silc_packet_context_free function. Added also new function
8081 silc_packet_context_alloc that must be used now to allocate the
8082 context. This also means that if a routine is asynchronous from
8083 silc_[client/server]_packet_parse_type the packet context must
8084 be duplicated by calling silc_packet_context_dup. Otherwise it
8085 gets free'd after silc_[client/server]_packet_parse_type returns.
8086 Also, one must remember that if packet is duplicated then its
8087 reference count must be decresed by calling the free function as
8088 many times as it was duplicated.
8090 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
8091 from both client and server.
8093 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8095 * Made joining to a channel working in router environment.
8097 * Cleaned up JOIN command on server side and create function
8098 silc_server_command_join_channel internal routine to make the
8101 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8103 * Changed silc_command_pending list to SilcDList. Also, added
8104 `ident' field to SilcServerCommandPending structure to identify
8105 the reply and to call correct callback.
8107 Added silc_server_command_pending_check function to replace the
8108 corresnponding macro. The silc_command_pending list is not
8111 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
8112 to set identifier to previously allocated Command Payload. It
8113 is used to set identifier for command when resending Command
8116 * Added silc_command_payload_encode_payload to encode Command
8117 Payload buffer from SilcCommandPayload structure.
8119 * Added silc_argument_payload_encode_payload to encode Argument
8120 payload buffer from SilcArgumentPayload structure.
8122 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8124 * Changed WHOIS command to support router connection on server side.
8125 The whois request is always sent to router unless the server is
8126 standalone server. After server has received the reply from the
8127 router will it send the reply to the client.
8129 * Added silc_server_packet_broadcast into silcd/server.[ch] to
8130 broadcast received broadcast packet. The function is used only
8131 by router. The broadcast packet is always sent to the router's
8134 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
8135 render given ID to printable string, for log files for example.
8137 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8139 * Made basic router to router connections working. At least they
8140 can now connect to each other but nothing really works the way
8141 they are supposed - yet.
8143 * Added new initiator token to RouterConnection configuration
8144 file in silcd/serverconfig.[ch]. It is used to tell whether we
8145 are the initiator to the remote router or whether we'll expect
8146 the other end to connect.
8148 * Moved registering of listener task to silc_server_init, hence
8149 the server starts listenning as soon as it is run, even if it
8150 does not have connections to other routers. Let's see how well
8153 * Changed default connection retry timeouts for more suitable in
8156 * Removed cipher and such arguments from silc_idlist_add_client
8157 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
8158 Added new function silc_idlist_add_data to add the keys and stuff
8161 * Added SilcIDListData structure and added it to SilcClientEntry
8162 and SilcServerEntry as their first field in the structure. This
8163 way we can explicitly cast the ID entries to the SilcIDListData
8164 structure and get common data for the entries. In past, we had
8165 to first check what type of connection it is and then cast it to
8166 correct ID entry type. Now, we can directly cast the opaque
8167 pointer to the SilcIDListData (no matter what ID entry it actually
8168 is) and get the data needed.
8170 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8172 * Wow, found a bug in scheduler. The scheduler uninitialized itself
8173 in some circumstances even if threre were timeout tasks, though not
8174 IO tasks, but tasks anyway. Now fixed.
8176 * Defined SilcServerConnection structure to hold connection specific
8177 stuff about directly connected servers and routers. The definition
8178 is currently in silcd/server_internal.h. I thought about having
8179 a bit more important role fro this struct but for now it is used
8180 only when connecting to other server (or router actually).
8182 * Added connecting retry support in server when connecting to
8183 router(s). The retry feature implement exponential backoff
8184 algorithm. Also, added SilcServerParams structure to hold default
8185 parameters for server. For now, it include these retry settings
8186 and are hard coded. After server is moded to be as Silc Server
8187 Library this structure will be more important.
8189 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8191 * Changed client librarys channel->clients table to SilcList and
8192 changed code accordingly.
8194 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8196 * Changed client's channel table to SilcList and changed code
8197 accordingly. Also changed SilcChannelClientEntry to include back-
8198 pointer to the channel so that client entry can use that structure
8199 as list as well and we have fast cross-reference to the channel.
8200 This change dramatically decreased the complexity of channel
8201 handling with client entry and vice versa (removed one extra
8202 loop when searching for channel entry from many functions).
8204 * Changed server->sim from table to SilcDList and changed code
8207 * NAMES command can now be used from user interface. It will show
8208 the user list on the channel, neatly.
8210 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
8211 Code now saves realname of the user if it becomes available.
8213 * Renamed configure.in to configure.in.pre and made ./prepare
8214 script to automatically add correct version string to
8215 configure.in which it creates from configure.in.pre.
8217 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8219 * NAMES command reply now shows users mode with the nickname when
8222 * Moved silc_client_ch[u]mode[_char] functions from
8223 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
8224 place sucks, they are utility functions and should be in some
8227 * Fixed some unsigned int's to unsigned short's. Patch by cras.
8229 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
8232 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8236 * Added TRQ (efficient deque and list library) into lib/trq. This is
8237 a very good list library that is currently used in the SILC. Defined
8238 SilcList API over the library because I didn't like the API very
8239 much. See lib/trq/silclist.h for the API and examples of how to
8240 use the API. Fixed various places in the code to use the new
8241 SilcList API. The SilcList is meant for lists that has a structure
8242 already defined as a list. It is not suitable to add just some
8243 context to the list (in TRQ, the context is the list actually).
8245 So, I defined SilcDList that can be used for the purpose where
8246 predefined list structure does not exit. This can be used as
8247 such list. Now some context just can be added to the SilcDList.
8248 Currently this list is not used in the SILC just yet, though there
8249 are a lot places where this can replace dynamically allocated
8250 tables and I will fix these places, later, to use SilcDList.
8251 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
8252 and use TRQ internally).
8254 Also fixed some annoying warning messages that the original TRQ
8255 code generated. Also minor changes to TRQ's Makefile.in.
8257 * Added support for querying by Client ID to both WHOIS and
8258 IDENTIFY commands into server, as required by the protocol.
8260 * Removed method function pointers from SilcBuffer structure. They
8261 weren't used to anything and just increased the context size for
8262 no good reason. This change also made silc_buffer_alloc and
8263 silc_buffer_free functions inline functions.
8265 * Disabled command flooding detection support until it's fixed so
8266 that it accepts commands in but does not execute them more than once
8269 * Added silc_net_localhost(), to return local hostname, into
8270 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
8271 that must be initialized before calling silc_client_init.
8273 * Added new function: silc_server_send_notify_on_channels to send
8274 notify messages to all channels client has joined. It is assured
8275 that the message is sent only once per client.
8277 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
8278 lib/silcutil/silcutil.[ch] as silc_format function. The new
8279 function is generic and is used by server as well, not only by
8280 the logging routines.
8282 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
8283 the provided version string was not acceptable. Added new function:
8284 silc_ske_check_version into lib/silcske/silcske.h. The function
8285 must be implemented by the application (client or server) and it
8286 does not reside in the SKE library. The function checks the version
8287 string remote end sent.
8289 * Added back pointers (to opaque context and to SilcSocketConnection)
8290 into SilcPacketContext structure into lib/silccore/silcpacket.h.
8292 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
8293 duplicate packet context structure.
8295 * Changed `notify' client operation to send same arguments as client
8296 receives from server except for ID's. ID's are mapped to correct
8297 ID entry and that is returned. Also, if channel entry is not sent
8298 by server but the notify is for channel the channel entry is sent
8299 to application (otherwise application doesn't know that it is for
8300 channel (library gets it from packet's Destination ID)).
8302 * Added silc_client_remove_from_channels into client library to
8303 remove a client from all channels it has joined to. Used when
8304 received SIGNOFF notify from server. Added also new function
8305 silc_client_replace_from_channels to replace old ID entry with
8306 new ID entry on all channels. Used when received NICK_CHANGE
8309 * Fixed ID Cache list handling in silc_idlist_get_client in
8310 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
8311 to get (or query) client by ID.
8313 * Updated TODO list.
8315 * Added connection authentication status message defined by the
8316 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
8317 support for these into the code in client and server side.
8319 * Added generic function silc_client_send_command to send any command
8320 with variable argument list. Application should use this function
8321 to send commands if the command functions provided by the library
8322 does not suite for the application's user interface needs.
8324 * Added new `failure' client operation. Application is notified about
8325 received failure packet if client is executing a protocol. In this
8326 case the protocol's execution has failed.
8328 * Added SKE's end notify to send the SKE_SUCCESS notify message that
8329 is required by the protocol.
8331 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
8332 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
8335 * Added status flag to SilcSKE object to indicate realtime status
8336 of the SKE protocol.
8338 * Application receives now exactly same command reply arguments as
8339 the library receives from server. However, if ID is received the
8340 corresponding ID entry is returned to the application (eg. Client
8341 ID is mapped to correct SilcClientEntry entry and that is returned).
8342 Changed command_reply client operation due to this change.
8344 * Changed all ID's in commands and in command replys as ID Payloads.
8345 Change affected both client and server side codes.
8347 All ID's sent in SILC network (with execption of ID's in SILC
8348 Packet header) are sent in ID Payload to support variable length
8351 * Server now notifies nick changes and notifies all clients on
8352 the channels about the new nickname (about the new Client ID,
8355 * Implemented CMODE command to change channel modes. Supports all
8356 channel modes defined by the protocol specs except ban and invite
8357 lists. (Also, private channel key mode is supported but support for
8358 setting private channel key in client is missing, thus, this mode
8359 has no effect on client side (except that server requires that the
8360 client uses private channel key and normal channel traffic does not
8363 Also, invite mode works per se, but INVITE command does not work
8364 yet correctly, so you can set channel as invite only channel but
8365 inviting clients to the channel does not work (it is yet to be
8366 thought what's the best way to do it).
8368 * Added new command SILC_COMMAND_CUMODE to change user mode on the
8369 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
8370 Implemented CUMODE command to change user's mode on the channel.
8371 Supports all modes defined by the protocol specs.
8373 * Added NAMES command reply to return users modes on the channel.
8375 * Removed unnecessary and slow ciphers from lib/silccrypt.
8377 * Set SO_KEEPALIVE option to connection sockets by default.
8379 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
8381 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
8382 redefined the Notify Payload into protocol specs.
8384 * Added silc_id_payload_parse_id to get ID directly from raw
8387 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8389 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
8390 accept searching by Client ID as well.
8392 * Added support for LEAVE and SIGNOFF notify types in client library.
8394 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
8395 to parse ID Payload from raw data.
8397 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8399 * Added flags parameter into silc_ske_assemble_security_properties
8400 function in lib/silcske/silcske.[ch].
8402 * Changed notify client operation to fit better for notify messages
8403 sent by server. The notify payload received from server is now
8404 passed to the application (after parsing it to SilcNotifyPayload).
8405 It is application's responsibility to retrieve the arguments
8406 from the payload and show the message the way it wants. The message
8407 sent by server is implementation specific.
8409 * Changed public keys to comply with the protocol specification.
8410 Old public keys are not supported anymore and are not compatible.
8412 * Removed nickname from Channel Payload as the latest draft removed
8413 it. The client must resolve the nickname from the NAMES command
8414 reply received when it joined the channel.
8416 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
8418 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8420 * Fixed some errors in protocol specification drafts.
8422 * Created lib/silccore/silcnotify.c to implement Notify Payload
8423 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
8424 generic payloads described by protocol specifications. The file
8425 includes implementations for ID Payload and Argument Payload.
8427 * Changed Command Payload implementation to use the new Argument
8428 Payload. Changed command_xxxx_payload to command_payload_xxxx
8429 to comply with SILC coding conventions.
8431 * Added suppport for Argument Payload handling in Notify Payload
8432 implementation as protocol requires it. Added the new support
8433 into server and client lib as well.
8435 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8437 * Added support for multiple nicknames on same channel. [n] is
8438 added locally to the nickname if there are more than one same
8439 nicknames on the channel.
8441 * Server now sends all nicknames that matched WHOIS request.
8442 Client also shows the list received from server.
8444 * Added TOPIC command to client side. User can now set and show
8445 current topic on channel.
8447 * Added MOTD command to client and server. Also, server sends the
8448 motd when client connects to the server.
8450 * Changed version strings to comply ISO 8601.
8452 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8454 * Fixed protocol error handling in client library. It should now
8455 cope even if the SKE fails for some reason.
8457 * Made new protocol specification drafts for submitting to IETF.
8459 * Implemented TOPIC command to server in silcd/command.c.
8461 * Added two new notify types into lib/silccore/silcnotify.h:
8462 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
8463 notify nickname change and topic setting/change on a channel.
8465 * API change of command_reply operation in client library. The
8466 application gets now the status type received from server as well.
8468 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8470 * Removed the function just added to lib/silcutil/silcschedule.[ch].
8472 * Cras fixed and optimized the packet handling even further and
8473 it should work now. Minor change to the prototype of function
8474 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
8476 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8478 * Added new function into lib/silcutil/silcschedule.[ch]:
8479 silc_schedule_with_fd to select() a specified fd. The function
8480 returns after timeout expires or data arrives or goes. The
8481 function is used by packet routines to wait that all data is
8482 received from network.
8484 * Fixed data reading from network in lib/silccore/silcpacket.c.
8485 The code now assures that all data is read from the fd and then
8486 continues packet processing. This was a bug fix since the code
8487 used to drop some data in some circumstances.
8489 * Added new function into lib/silcclient/client.[ch]:
8490 silc_client_start_key_exchange to start key exchange after
8491 connection has been established to server. The code internally
8492 now uses this funtion but its main purpose was to provide it
8493 for applications that perform their own connecting. After
8494 application has created a connection it merely calls this
8495 function to start the key exchange between client and server.
8496 The library takes care of everything else after that.
8498 Updated also lib/silcclient/README to explain the usage of
8501 * Do not send to application information that connection has
8502 been established. Application gets notified it by connect
8505 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8507 * Applied cras's patch to add silc_schedule_one function. The
8508 function runs scheduler once and returns.
8510 * Fixed the scheduler after cras messed it up. The timeout
8511 handling works now as it's supposed to work.
8513 * Added into lib/silccore/ silcnotify.h to include notify
8514 message types support. Changed silc_server_send_notify*
8515 functions, in server.[ch], to support those new notify types.
8516 Added the support for the notify types into client library,
8517 as well. Added new notify client operation into ops.h in
8520 * Changed silc_server_packet_send_to_channel to send normal
8521 packets instead of just channel message packets. The function
8522 is now used to send the notify packets to channels. It is not
8523 used to send channel message packets anymore, as server never
8526 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
8527 va_arg()s as it seems to require it nowadays. I guess, if SILC
8528 is compiled with older va_arg() the new code should work anyway.
8530 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8532 * Splitted core library. Core library (lib/silccore) includes
8533 now only SILC protocol specific core (and common) components.
8534 Created new utility library (lib/silcutil) that includes more
8535 generic purpose stuff. The stuff for util library was taken
8536 from the old core library. This was minor and easy split.
8538 * Created SILC Client Library (lib/silcclient) that includes
8539 implementation of the SILC client without user interface. This
8540 was major move from silc/ directory. The code has been changed
8541 so that it is transparent towards the user interface. The
8542 silc/ directory includes now the same user interface as before
8543 and it uses the new client library. Read lib/silcclient/README.
8544 Basicly, the client library performs everything else related
8545 to SILC except user interface handling. Also, configuration
8546 files are considered to be part of user interface and library
8547 does not handle them.
8549 This change also changed a lot of structures, function naming etc.
8550 Most important change was that SilcClientWindow object was
8551 renamed to SilcClientConnection in the client library. Created
8552 also new file lib/silcclient/ops.h. Also added new files
8553 silc/local_command.[ch] and silc/client_ops.[ch].
8555 All these changes were made to make it easier for user interface
8556 designers to create what ever user interface for the SILC client
8559 It is also expected that the server will be moved to lib
8560 directory as well and SILC Server Library will be created;
8561 sometimes in the future.
8563 * Removed Local commands from lib/silccore/silccommand.h as
8564 they are application specific and new client library does not
8565 handle any of those anymore.
8567 * Several functions moved to lib/silcutil/silcutilc.[ch] from
8568 old client implementation in silc/.
8570 * Added support for callback functions in SILC_LOG_* macros.
8571 Application can now set its own callbacks that will be called
8572 instead of using the default functions that will always print
8573 the debug messages to stderr (or stdout). Also, debugging can
8574 now be disabled by setting silc_debug to FALSE and re-enabled by
8575 setting it to TRUE. Note, that logging will still work even
8576 if debugging is disabled.
8578 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
8579 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
8580 silc_log_reset_debug_callbacks.
8582 * To enable debugging in silc client one must give now -d
8583 option on command line.
8585 * Changed silc_schedule_init to automatically allocate task queues
8586 if they are not allocated before calling it.
8588 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8590 * Added GMP 3.1 into math library.
8592 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8594 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
8595 a channel in SILC network. The packet is used by servers and
8596 routers to notify other routers that user has left a channel.
8597 This little feature was missing until now. Added the feature
8598 to protocol specification as well.
8600 Added functions: silc_server_send_remove_channel_user and
8601 silc_server_remove_channel_user into server.[ch].
8603 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
8604 lib/silccore/silcpacket.h. However, they are not implemented
8607 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8609 * Fixed joining to a channel and sending channel messages
8610 between server and router. The channel message sending should
8611 now work inside a cell.
8613 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8615 * Fixed the private message sending between server and router.
8616 The private message sending should now work inside a cell.
8618 * Added silc_server_replace_id into server.[ch] to replace
8619 existing ID in the SILC network.
8621 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
8622 and silc_idlist_replace_server_id into idlist.[ch] in server.
8624 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8626 * Fixed the server to server connections. Server can again now
8627 connect to router. Router to router connections probably does
8630 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8632 * Added dynamic protocol registering support. Now protocols can
8633 registered and unregistered on the fly. Patch by cras.
8635 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8637 * Added lib/contrib directory to hold routines that some platforms
8638 don't have but are needed by SILC.
8640 * Added getopt.c, getopt1.c and getopt.h from GNU C library
8641 into lin/contrib to provide getopt() and getopt_long() for
8642 those who don't have it.
8644 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8646 * Added AWAY command to client. When away message is set and
8647 client receives a private message packet the client automatically
8648 replies to the sender with the away message.
8650 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
8651 bug seemed to be the cause of recent problems when compiling
8654 * Added version detection support to SKE protocol specification
8655 and added the new changes to the SKE implementation as well.
8656 There were other minor changes in the SKE protocol as well.
8658 Many changes in lib/silcske/silcske.[ch] and in
8659 lib/silcske/payload.[ch].
8661 * Added ^U functionality, clear input line. Patch from cras.
8663 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8665 * Mainly small bugfixes on core library. Fixed some debugging
8666 logging and buffer overflow in silclog.c.
8668 * Updated config.sub and config.guess on the distribution tree.
8670 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8672 * Added command lagging support in server. Client may execute
8673 commands now only once in two seconds.
8675 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8677 * Optimized packet reception. MAC computation and checking is now
8678 also more optimized. A lot previously duplicated code is now
8679 used as generic by both client and server.
8681 * Fixed key pair generation in clientutil.c
8683 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8685 * Added into lib/silccore/silcbufutil.[ch] new function;
8686 silc_buffer_realloc.
8688 * Moved generic packet sending/encryption functions to
8689 lib/silccore/silcpacket.[ch] from client and server. Some
8690 rewriting of the functions.
8692 * Moved all generic packet reception/decryption functions to
8693 lib/silccore/silcpacket.[ch] from client and server. The
8694 packet processing is now much cleaner in both client and server.
8695 These were major changes in both client and server.
8697 * Created many common functions in server to do packet sending.
8698 Previously code were duplicated a lot, this has been removed
8701 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8703 * Rewrote major parts of the ID cache system. Don't know
8704 whether it is better now or not but at least the API is more
8707 * Major rewrite on ID cache stuff on client because of the ID
8708 cache API changes. Added idlist.c to client.
8710 * Also major rewrite on ID cache stuff on server as well.
8711 Major rewrite of idlist.[ch]. SilcXXXList's are now named
8712 SilcXXXEntry's. We won't keep anymore idlist specific pointers
8713 in hand, instead they are all put into the ID cache system now.
8714 All server_idlist_* routines uses ID cache now instead of
8715 traversing its own lists (those lists does not exist anymore).
8716 SilcIDList though still exists. Also, SilcXXXEntry's are
8719 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8721 * Finally made the SKE implementation compliant to the protocol
8722 specification. All mp integers are now binary encoded as
8723 opposed being HEX encoded.
8725 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
8728 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
8729 functions: silc_[encode/decode]_pem. Also added function
8730 silc_encode_pem_file to PEM encode with newlines ('\n') for
8733 * SILC public keys are now encoded either PEM or binary. Same
8734 option is for private keys as well. By default private keys
8735 are binary encoded and public keys PEM encoded. Silly HEX
8736 encoding were removed.
8738 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
8739 function to create fingerprints.
8741 * Fixed a bug in SHA1; does not change the original data anymore.
8743 * Partly implemented INFO command on client and server side.
8744 Fixed CLEAR command. Changes to SERVER command; show current
8745 server(s) when giving command without arguments. Added
8746 VERSION command to client.
8748 * Added check to server that unregistered connections cannot
8749 execute commands (unless it is specificly allowed).
8751 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8753 * Fixed screen refresh.
8755 * Fixed channel joining bug from client. On some circumstances
8756 client tried to join to a channel it had already joined.
8758 * Added public key verification process into client's protocol.c.
8759 The client now verifies the public key from user and saves
8760 it into ~./silc/serverkeys/ directory.
8762 Added into: clientutil.[ch]: silc_client_verify_server_key.
8764 * Changed SKE protocol's silc_ske_initiator_finish function
8765 to accept callback function that verifies the received public
8766 key. Removed old silc_ske_verify_public_key function.
8768 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8770 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
8771 silc_pkcs_private_key[_data]_set.
8773 * Made the password and public authentication more cleaner in
8774 server's protocol.c.
8776 * Removed historic and obsolete protocol `channel_auth' from
8777 both client and server.
8779 * Removed wrong way of sending command status messages from
8780 server to client in server's command.c. The old way violated
8781 protocol specification.
8783 Changes to silccore/silccommand.[ch]: removed
8784 silc_command_encode_status_payload -> not needed anymore,
8785 changed silc_command_encode_payload_va to accept extra
8786 argument on variable argument list. The argument type must
8787 now be provided to the function. Also, added new function:
8788 silc_command_encode_reply_payload_va which is same as
8789 normal command_encode_payload_va except command status type
8790 is provided as extra argument.
8792 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8794 * Added ~./silc directory handling. The directory includes the
8795 public and private keys for the client.
8797 Added silc_client_check_silc_dir, silc_client_create_identifier
8798 and silc_client_load_keys.
8800 * Implemented SILC protocol compliant public key. Added public
8801 and private key saving to and loading from files.
8803 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
8804 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
8805 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
8806 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
8807 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
8809 Implemented: silc_pkcs_save_[public/private]_key[_data] and
8810 silc_pkcs_load_[public/private]_key.
8812 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8814 * Added silc_server_get_route (route.[ch]) to get connection
8815 data for the fastest route for given ID.
8817 * Implemented INVITE command on client and server. The command
8818 were re-defined in the SILC Protocol Specification and the
8819 implementation now complies with the specification.
8821 * Implemented PING command on client and server.
8823 * Implemented NAMES command on client and server. The server side
8824 supports currently only normal server not router server yet.
8825 Some changes to NAMES definition in SILC protocol specification.
8827 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8829 * Implemented LEAVE command on client and server.
8831 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
8832 again. This change was made to the protocol as well. Server
8833 should not violate the protocol specification anymore.
8835 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8837 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
8838 was tested. SOCKS4 was not but should work anyway.
