759 It is not able to send requested attributes in WHOIS command,
760 and also receive and process requested attributes. Added
761 silc_client_attribute_[add|del] and silc_client_attributes_get
762 functions. Added also `ignore_requested_attributes' to the
763 SilcClientParams to not use attributes in client. Affected
764 files are lib/silcclient/command.c, client_attrs.[ch],

785 * Changed the silc_attribute_payload_encode to support list
786 of attributes (function may be called several times to add
787 a new attribute). Removed the silc_attribute_payload_encode_list
788 function. The encoding function now also automatically encodes
789 the data, so the caller does not need to do that. Affected
790 files lib/silccore/silcattrs.[ch].
792 * Added support for replying on behalf of the user to the
793 Requested Attributes in WHOIS command in the server. Affected
794 file silcd/server_query.c.

861 Mon Sep 16 12:02:54 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
863 * Added 'app_context' to silc_schedule_init. It is an
864 application specific context that is delivered to application
865 in task callback functions. Affected files are
866 lib/silcutil/silcutil.[ch].
868 * The hb_context in SilcSocketConnection is not freed
869 automatically anymore (application must free it). Freeing
870 it automatic is inconsistent. Affected files are
871 lib/silcutil/silcsockconn.[ch].
873 Sun Sep 15 22:16:19 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
875 * Added support for removing explicitly added client connections
876 in rehash and closing the client connections if they were

909 Mon Sep 9 12:18:18 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
911 * Incoming file transfer request cannot use same session as
912 the sending session. This can happen when sending file to
913 yourself. Crashed the client on quit. Affected file
914 lib/silcclient/client_ftp.c. Bug #24.
916 Sun Sep 8 18:39:25 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

919 the Attribute Payload into the lib/silccore/silcattrs.[ch].
921 Sun Sep 8 13:13:44 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
923 * Distribute the SERVER_SIGNOFF notify also to local backup
924 routers from the primary router. The backup router may not
925 have the signing of local server directly connected and need
926 to know about the signoff. Affected file silcd/server_util.c.
928 * Use the primary router as the origin of the locally connected
929 server when it is disconnecting from the backup router since
930 that's where it really is coming from. Now the clients from
931 the disconnecting server are removed correctly and "shadow"
932 clients are not left to the backup router. Affected file
935 Sat Sep 7 22:26:50 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
937 * If normal server is standalone and found existing but disabled
938 channel, do not re-create the channel since it creates
939 duplicate same channels. Affected file silcd/server.c.
941 * Added anonymous client connections support to server. New
942 "anonymous" configuration option to ConnectionParams section
943 added. If set to true, the username and hostname information
944 of the client will be scrambled and anonymous user mode is
945 set automatically to the user. Affected files are
946 silcd/serverconfig.[ch], silcd/packet_receive.c and server.c.
948 Sat Sep 7 16:02:09 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
950 * In JOIN notify handling, mark that the cache entry of the
951 client cannot be expired. Can cause crashes on normal
952 server (asserts client->channels). Affected file is
953 silcd/packet_receive.c.
955 * From now on distribution versions are used as protocol versions
956 instead of by default using the Toolkit base version as protocol
957 version. Affected file prepare.
959 * Do not set the locally resolved hostname for local client
960 entry but take what server sends. This way the real hostname
961 is showed in WHOIS for yourself. Affected file is
962 lib/silcclient/idlist.c and lib/silcclient/client.c.
964 * Resolve local info with IDENTIFY when connecting to server.y
966 Sat Sep 7 14:22:43 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
968 * Rewritten check for POSIX threads. Use --with-pthreads[=DIR]
969 for implied search (not needed on platforms which has native
970 pthreads library). Use --without-pthreads to disable threads.
971 Affected file is configure.in.pre
973 * Fixed --with-iconv on platforms which need to bypass (broken)
974 native iconv(). Affected file is configure.in.pre
976 Sat Sep 7 15:08:13 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
978 * Moved -C option parsing in Irssi SILC client at same time
979 as other options. The UI was initialized earlier and caused
980 problems on command line. Bug #16. Affected file is
981 irssi/src/silc/core/silc-core.c.
983 Mon Sep 2 23:00:30 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
985 * Added global variable silc_log_timestamp that tells silclog
986 wether to print or not the timestamp in the logging files.
987 Affected file lib/silcutil/silclog.[ch].
989 * Added silcd configuration option Timestamp in the Logging
990 section. Affected file silcd/serverconfig.[ch],
991 doc/example_silcd.conf.in.
993 Fri Aug 30 08:57:33 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
995 * Fixed fingerprint checking to check for entirely empty
996 fingerprint instead of two first bytes when determining
997 if it is set. Bug #18. Affected file silcd/command.c.
999 * Fixed duplicate PKCS name registering to not allow it.
1000 Bugs #17. Affected file lib/silccrypt/silcpkcs.c.

1014 Fri Aug 23 22:05:44 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
1016 * Rewrote iconv checking, introduce --with-iconv for systems
1017 which rely on libiconv. Check if iconv() provided by libc
1018 is good enough, otherwise demand libiconv. Affected file
1021 Fri Aug 23 07:10:52 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
1023 * Search for ldopen() also in libc. This enables SIM support

1053 Affected file silcd/command.c.
1055 Tue Jul 9 19:03:11 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1057 * Fixed buffer overflow and security problems (loosing bits
1058 in CFB encryption) in SILC RNG. Problems reported by
1059 Markku-Juhani O. Saarinen <mjos@saturn.tcs.hut.fi>.
1061 Sun Jul 7 13:10:01 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1063 * Added yet more checks that client is not expired on global
1064 list if it is on channels. Affected file is
1065 silcd/command_reply.c.
1067 Sat Jul 6 11:45:11 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1069 * Merged c0ffee's MIME signal patch which adds support for
1070 sending also MIME messages in Irssi SILC Client, and handling
1071 received MIME messages in a signal (and perhaps doing something
1072 to non-textual MIME messages).
1074 Sun Jun 30 01:30:22 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1076 * Fixed pending command deletion in server and client library
1077 to check the whole list instead of breaking after first found.
1078 The affected files are silcd/command.[ch] and
1079 lib/silcclient/command.[ch].
1081 Sat Jun 29 17:40:12 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1083 * Return NO_SUCH_CHANNEL error in USERS for channel that is
1084 secret or private, otherwise it's possible to find out
1085 whether a secret channel exists or not. Affected file
1088 * If CMODE change fails during the mode setting, assure that
1089 the old mode mask is set for the channel back. Affected
1090 file silcd/command.c.
1092 * Fixed passphrase saving on +a channel on normal server
1093 after successful JOIN command. Affected file silcd/command.c.
1095 Fri Jun 28 11:53:25 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
1097 * Remove server/router operator privileges in DETACH command,
1098 since it's possible to resume to server where these

1103 Affected file silcd/server.c.
1105 * Do not check listener sockets when counting how many
1106 socket connections we have. Affected file is
1107 silcd/server_util.c.
1109 * Do not announce disconnected clients that are remaining
1110 in history (for WHOWAS). This is because SIGNOFF notify
1111 for these has been sent earlier already. Affected file
1114 Thu Jun 27 20:07:27 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1116 * Buffer overflow with CUMODE command's mode->mode character
1117 conversion. Reported by Ville Räsänen. Affected file
1118 lib/silcutil/silcutil.c.
1120 Thu Jun 27 16:54:33 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1122 * Allow heartbeat packets to go disabled connections anyway.
1123 Affected files silcd/server.c and silcd/packet_send.c.
1125 * Do not broadcast New Channel packets with List flag set
1126 in the packet to backup routers. The router must check
1127 for the correctness of the packets before sending them.
1128 It is possible that router will have enforce Channel ID
1129 change and this would cause desync in the backup router.
1130 Affected file silcd/packet_receive.c.
1132 * Remove SILC_PACKET_FLAG_LIST from the temp packets that
1133 are handled in list parsing. They are not list packets
1134 anymore. Affected file silcd/packet_receive.c.
1136 Thu Jun 27 11:27:07 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
1138 * Stop waiting for backup router through the timeout, not
1139 directly after backup router has arrived. Affected file
1142 * Do not re-create channel keys and send them when removing
1143 clients in server shutdown. Affected files are
1144 silcd/server_internal.h and silcd/server_util.c.
1146 * Notify distribution to backup routers was missing from
1147 the silc_server_send_notify_dest function which caused
1148 desyncing problems with backup router. Affected file is
1149 silcd/packet_send.c.
1151 * The client's channel removing was working wrong on
1152 backup router. It assumed that it doesn't know global
1153 information but backup router does know. For this reason
1154 it could remove channel when it wasn't supposed to do that.
1155 Affected file silcd/server.c and silcd/server_util.c.
1157 Wed Jun 26 15:14:12 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1159 * Stop for a couple seconds after badkup router has become
1160 primary router. Affected file silcd/server.c.
1162 * Added silc_server_remove_servers_by_server, which is used
1163 to remove servers originated from some other server. Also
1164 clients of those servers can be removed too. Affected file
1165 silcd/server_util.[ch].
1167 * When removing clients after a server has signed of remove
1168 also all servers behind that server (unless they are known
1169 to be available locally), and send SERVER_SIGNOFF for each
1170 of the server separately. Also the signed off clients are
1171 sent now separately per signed off server. The affected files
1172 are silcd/server.c and silcd/server_util.[ch].
1174 * All servers added with silc_idlist_add_server must always
1175 have both "router" and "connection" pointers set. Otherwise,
1176 bad server entries may be left around in the cache.
1177 Affected file silcd/command_reply.c.
1179 * Do not create the channel key in NEW_CHANNEL packet
1180 processing if the channel is empty. Affected file
1181 silcd/packet_receive.c.
1183 * Completed backup router support for standalone routers.
1184 Supports also servers in the cell that do not use the backup
1187 Wed Jun 26 10:38:11 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1189 * Fixed a bug in silc_string_regexify which did not add '^'
1190 at the start of each string, and thus the matching was
1191 not explicit. For example ban list iikone@*!*@* would
1192 match also "priikone", which is wrong, it would have to be
1193 *iikone@*!*@* to match also "priikone". Affected
1194 file lib/silcutil/unix/silcunixutil.c.
1196 Tue Jun 25 18:47:39 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1198 * Enable all local server connections before updating client
1199 caches when we've become backup router. Otherwise, signoff
1200 packets may not reach the clients. Affected files are
1201 silcd/server.c and silcd/server_util.[ch].
1203 * Fixed a bug in version string parsing which could crash
1204 the program with specially formatted version string.
1205 Bug reported and patch provided by Ville Räsänen. Affected
1206 file lib/silcutil/silcutil.c.
1208 * Handle the disconnection immediately when DISCONNECT
1209 packet is received in server. Affected file silcd/server.c.
1211 * Primary router now waits a short time (10 seconds) for
1212 backup router connection before accepting any other
1213 connection (except local). Affected file silcd/server.c,
1216 * Fixed a crash in client libary in NICK_CHANGE notify when
1217 NICK_CHANGE arrived for client entry we are resolving
1218 currently. Affected file lib/silcclient/client_notify.c.
1220 * Call the sconn->callback completion even if error had
1221 occurred. Start reconnecting always if connection to
1222 primary router fails during backup router protocol.
1223 Affected files silcd/server.c and server_backup.c.
1225 Mon Jun 24 17:47:52 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1227 * Added functions silc_server_send_opers and
1228 silc_server_send_opers_notify to send packets stricly
1229 to operators. Added macro SILC_SERVER_SEND_OPERS macro
1230 to send variable argument notify to operators.
1231 Affected files silcd/packet_send.[ch] and silcd/server.h.
1233 * Removed UMODE rights checking with UMODE_CHANGE notify.
1234 Affected file silcd/packet_receive.c.
1236 * Server/router operator now receives notify when network
1237 switches to backup router and when it resumes the use of
1238 primary router. Affected file silcd/server.c and
1239 silcd/server_backup.c.
1241 * Fixed the updating of client information after backup
1242 resuming protocol is over; update all except local clients
1243 to the new primary router. The affected file is
1244 silcd/server_util.c.
1246 * Added support for closing active connections in rehash
1247 that were unconfigured by the user. Supports currently
1248 closing server and router connections. Affected file
1251 * Rewrote some SILC_LOG_DEBUG's in silcd/server_backup.c.
1253 Sun Jun 23 17:32:31 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1255 * Don't do SILC_STRING_LANGUAGE encoding if the outbuffer
1256 is NULL since seems that on some platforms NULL is allowed
1257 and on some it's not. Fallback encoding is used instead.
1258 Affected file lib/silcutil/silcstrutil.c.
1260 * Fixed statistics updating for incoming server connection
1261 which could cause problems when re-connecting. Affected
1262 file silcd/server.c.
1264 * Preliminary backup router support for standalone router
1265 added. Affected files in silcd/.
1267 * Mark server connections in backup router disabled before
1268 and after backup protocol. Affected file is
1269 silcd/server_backup.c.
1271 * Added support for reconnecting to remote server connection
1272 even if the protocol fails, and if the configuration wants
1273 us to keep trying to connect anyway.
1275 Server connection is not allowed to backup router if
1276 backup router does not have connection to primary router yet.
1278 Affected file is silcd/server.c.
1280 Sat Jun 22 21:34:59 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1282 * Added silc_client_udpate_server function to update changed
1283 server info. Affected file lib/silcclient/idlist.[ch].
1285 * Added check for server entries that are being resolved when
1286 notify is received. If being resolved, handle the received
1287 notify only after it's resolved so that all notifys are
1288 handled in same order as received from the server.
1290 Added similar resolver check to channel entries. Every
1291 notify that cause resolving of any information that affects
1292 channel entry marks the channel entry in waiting state.
1293 After whatever resolving is over the waiters are signalled
1294 and only then the notifys are handled in the same order
1295 as delivered from the server.
1297 Affected files are lib/silcclient/idlist.[ch], and
1300 * Fixed KILLED notify handling in normal server. Affected
1301 file silcd/packet_receive.c.
1303 * Added SILC_IDLIST_STATUS_LOCAL which indicates that entry
1304 is locally connected, or was locally connected (but may
1305 be detached and connection is not active). Added also
1306 SILC_IS_LOCAL for checking this status. Affected files
1307 silcd/idlist.h, silcd/packet_receive.c, silcd/server_util.c,
1308 silcd/server.c and silcd/server_internal.h.
1310 Sat Jun 22 17:06:58 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1312 * Don't send or handle TOPIC_SET if topic is already set and
1313 is same as being set. Affected files silcd/command.c and
1314 silcd/packet_receive.c.
1316 * Fixed CMODE change rights checking to work correctly when
1317 removing modes by operator. Affected file is
1318 silcd/server_util.c.
1320 * Fixed some handling with New Channel packet in router and
1321 fixed some CMODE_CHANGE notify handling in server and router.
1322 Affected file is silcd/packet_receive.c.
1324 * Changed "disconnect" client operation to include the
1325 reason of the disconnection and optional disconnection
1326 message. Affected file lib/silcclient/silcclient.h.
1328 * Made the compilation of lib/contrib/ stuff conditional.
1329 Affected files configure.in.pre, lib/contrib/Makefile.am.
1331 Sat Jun 22 12:49:21 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1333 * All CMODE_CHANGE and CUMODE_CHANGE notifys are now sent back
1334 to the sender of the notify too, to avoid situation where two
1335 notifys are in the network at the same time going to oppsite
1336 directions. Affected file silcd/packet_receice.c.
1338 Fri Jun 21 10:00:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1340 * Delete the client from channel even if the cilent->id is
1341 NULL. It was possible that client was deleted without
1342 removing from channels (theoretically at least). Affected
1343 file silcd/server.c and silcd/server_util.c.
1345 * Free the client data too when resuming is not successful.
1346 Affected file silcd/packet_receive.c.
1348 * Merged some code from c0ffee's silc-plugin. Affected files
1349 irssi/src/silc/core/silc-channels.c and silc-expandos.c.
1351 * Added SILC_PRIMARY_ROUTE and SILC_BROADXAST macros to
1352 silcd/server_internal.h. SILC_PRIMARY_ROUTE Returns pointer
1353 to the primary router connection, the other one returns
1354 TRUE if packet must be broadcasted to network.
1356 * All notifys that are destined to primary router (to network)
1357 are now automatically sent to backup routers even if the
1358 router is standalone (and has backup router). Affected files
1361 * Added --without-irssi and --without-silcd configuration
1362 options for disabling the compilation of these applications.
1363 Affected file configure.in.pre and prepare.
1365 Thu Jun 20 13:48:15 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1367 * Implemented SILC_STRING_BMP and SILC_STRING_UNIVERSAL for
1368 UTF-8 encoding and decoding. Added also new encodings
1369 SILC_STRING_BMP_LSB and SILC_STRING_UNIVERSAL_LSB.
1371 Added also SILC_STRING_LANGUAGE which is language and charset
1372 specific encoder and decoer for those platforms that support
1373 iconv(). It can convert the UTF-8 to and from the locale
1374 specific character set.
1376 Affected file lib/silcutil/silcstrutil.[ch].
1378 * Added macro SILC_NOT_IMPLEMENTED to lib/silcutil/silclog.h.
1380 * Added function silc_get_command_name to the file
1381 lib/silcutil/silcutil.[ch].
1383 * Improved the server debug output a bit. Affected files are
1386 Wed Jun 19 17:46:31 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1388 * Save the channel passphrase when received succesful JOIN
1389 command reply from router, on normal server. Otherwise
1390 joinig +a channels from normal server is not possible.
1391 Affected file silcd/command.c.
1393 * Fixed a bug in TOPIC_SET notify handling. The notifier
1394 may be other than client too, like server or channel.
1395 It expected it to always be only client and ignored the
1396 notify. Affected file silcd/packet_recieve.c.
1398 * Removed some (unnecessary) debug printing from
1399 lib/silccore/silcid.c and lib/silccore/silcargument.c.
1401 * Do not force CMODE_CHANGE when server is announcing new
1404 Router announces stuff only after server reannounces channel
1405 after CHANNEL_CHANGE notify.
1407 These fixes optimizes the announcing procedure, and perhaps
1408 fixes some problems too. Affected file silcd/packet_receive.c.
1410 * Fixed SERVER_SIGNOFF sending to local clients. It was
1411 totally broken and sent the notify to all local clients,
1412 instead of only to those that was on same channel as the
1413 signing off clients. Affected file silcd/server_util.c.
1415 * Added -D option to server. It can be used to give debug
1416 level. The levels are from 0 - 99, and are predefined for
1417 smooth server debugging. (see silcd.c for the predefined
1418 levels). Affected file silcd/server.c.
1420 Wed Jun 19 16:01:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1422 * Fixed a bug in Irssi SILC client to close the connection
1423 properly when disconnecting from server. Affected file
1424 irssi/src/silc/core/client_ops.c.
1426 Tue Jun 18 17:14:52 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1428 * When authenticating as founder during JOIN command, check
1429 that the one authenticating becomes the only founder on the
1430 channel. Affected file silcd/command.c.
1432 * Better checking for founder mode setting when CUMODE_CHANGE
1433 notify is received. Affected file silcd/packet_receive.c.
1435 * Close all connections when shutting down the server by sending
1436 DISCONNECT packet. Close all listeners too when shutting
1437 down the server. Affected file silcd/server.c.
1439 * Handle DISCONNECT packet correctly in client library by
1440 calling the "disconnect" client operation. Affected file
1441 lib/silcclient/client.c.
1443 * Handle local errors correctly during resuming. Affected
1444 file lib/silcclient/client.c.
1446 Tue Jun 18 10:26:27 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1448 * The log file is not dupped internally anymore in
1449 lib/silcutil/silclog.c. Fixed memory leaks too.
1451 * The scheduler now dispatches all pending timeout tasks
1452 when it is uninitialized with silc_schedule_uninit.
1453 Affected file lib/silcutil/silcschedule.c.
1455 Mon Jun 17 21:30:55 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1457 * Added --enable-stack-trace option to configure. Added
1458 memory allocation stack trace support. Added files
1459 lib/silcutil/stacktrace.[ch]. Affected files are
1460 lib/silcutil/silcmemory.[ch].
1462 * Fixed memory leaks from libraries and server. Affected
1463 files around the tree.
1465 * Reverted back a fix made to CUMODE which broke it.
1466 Affected file silcd/command.c.
1468 Sun Jun 16 11:49:45 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1470 * Added SILC_MESSAGE_FLAG_UTF8 to the protocol specs and the
1471 core library, and implemented it. All textual messages SHOULD
1472 use this flag and the message MUST be UTF-8 encoded.
1473 All text messages sent by Irssi SILC client are now UTF-8
1474 encoded (regardless whether the terminal supports UTF-8 or not).
1475 Affected files are lib/silccore/silcchannel.h,
1476 irssi/src/silc/core/silc-servers.c, silc-channels.c and
1479 Sat Jun 15 18:23:39 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1481 * Added lots of new statistics updating that was missing from
1482 the server and router code. Affected files in silcd/.
1484 * Sending SIGUSR1 signal to server now dumps the current
1485 server statistics into /tmp directory. Affected file is
1488 * ROBODoc documented the lib/silccrypt/silchash.h. Improved
1489 the SILC Hash Interface also. Added new functions
1490 silc_hash_get_name, silc_hash_init, silc_hash_update and
1491 silc_hash_final. Affected file lib/silccrypt/silchash.c.
1493 Sat Jun 15 12:09:14 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1495 * Added some better info printing for client during connecting.
1496 Affected file silcd/server_util.c.
1498 * Implemented the SILC_CHANNEL_UMODE_QUIET mode that can be used
1499 to silence a user on a channel. Affected files are
1500 lib/silcclient/client_channel.c, irssi/src/silc/core/client_ops.c,
1501 irssi/src/fe-common/silc/module-formats.[ch], silcd/command.c
1502 and silcd/packet_receive.c.
1504 * Fixed a fatal bug in handling of malformed command payload.
1505 Affected file silcd/command.c.
1507 * Fixed a double free when announcing channel users to router.
1508 Affected file silcd/server.c.
1510 * After successful authentication to channel founder mode, check
1511 that there isn't anyone else with founder mode on the channel.
1512 The one that authenticated will become founder and anyone
1513 else is demoted. Affected file silcd/command.c.
1515 * Added error printing of any error that has occurred during
1516 any command in client library. Affected file is
1517 irssi/src/silc/core/client_ops.c.
1519 * Removed some error printing from the client library and left
1520 it for the application to worry (from the error status it
1521 receives in 'command' client operation. Affected file is
1522 lib/silcclient/command.c.
1524 Fri Jun 14 22:59:02 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1526 * Added new status types KEY_AGREEMENT_ALREADY_STARTED and
1527 KEY_AGREEMENT_SELF_DENIED to lib/silcclient/silcclient.h.
1528 Starting key agreement with itself is denied. Affected file
1529 is lib/silcclient/client_keyagr.c.
1531 * Fixed some error checkings from the SFTP library which caused
1532 misbehaviour. Affected files are lib/silcsftp/sftp_client.c
1533 and lib/silcsftp/sftp_util.c.
1535 * Added new "debug" and "debug_string" settings to Irssi SILC
1536 client which can be used to print runtime debugging on the
1537 Irssi's screen. Available when compiled with --enable-debug
1538 option. Affected file irssi/src/silc/core/silc-core.c.
1540 Tue Jun 11 16:36:02 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
1542 * Fixed a missing variadic parameter in a function call that
1543 caused server crash when a non-allowed connection arrived.
1544 Reported by Richard Becker. Affected file silcd/server.c.
1546 Mon Jun 10 16:29:42 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1548 * Added WATCH list sending to backup routers from router.
1549 The WATCH command is sent by the router to the backup
1550 router. Affected file silcd/command.c.
1552 * Mark the backup_router flag for RouterConnection entry
1553 if the backup router stuff is defined in the config file.
1554 Affected file silcd/serverconfig.c.
1556 * Fixed some backup data sending around the code to work better
1557 if the router is standalone router. Not all places were fixed.
1558 Affected file silcd/packet_receive.c, silcd/packet_send.c,
1561 * Fixed the router connecting when connecting to multiple
1562 routers. It ignored every other router except the first
1563 one. Affected file silcd/server.c.
1565 Mon Jun 10 09:28:21 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
1567 * Made the private key generation after expiration optional.
1568 If not created after expiration the old key will re-expire
1569 at a later time (and thus key pair is not necessary to
1570 change). Affected file irssi/src/silc/core/clientutil.c.
1572 Sun Jun 9 18:58:25 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1574 * The length arguments in bind() and connect() were wrong
1575 and fixed now to used SIZEOF_SOCKADDR in the
1576 lib/silcutil/unix/silcunixutil.c.
1578 Tue Jun 4 18:36:05 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1580 * Fixed detach timeout handling to use Client ID and not
1581 the actual client entry which may be freed in the callback.
1582 Affected file silcd/command.c.
1584 Thu May 30 15:53:45 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
1586 * Merged c0ffee's multiple interface support patch.
1587 Affected files in silcd/.
1589 Wed May 29 18:08:15 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1591 * Cleanup keys properly. Affected file is
1592 irssi/src/silc/core/clientutil.c.
1594 Tue May 28 20:11:41 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1596 * Display the user mode on the status bar. Affected file
1597 irssi/src/silc/core/silc-expandos.c.
1599 Tue May 28 13:56:26 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
1601 * If private message key is not set, but the flag is set in
1602 the packet, ignore the packet since it cannot be decrypted.
1603 Affected file lib/silcclient/client_prvmsg.c.
1605 Thu May 23 12:00:14 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
1607 * When resuming client, remove the old client entry from
1608 the watcher list too. Affected file silcd/packet_receive.c.
1610 * Do not allow normal server to force founder mode away
1611 from router if the founder mode is already set. Affected
1612 file silcd/packet_receive.c.
1614 * Remove the client entry with watch notify types with short
1615 timeout, and not directly, so that other notifys can be
1616 retrieved too. Affected file lib/silcclient/client_notify.c.
1618 * Display notification about data messages that cannot be
1619 displayed. Affected files irssi/src/silc/core/client_ops.c,
1620 irssi/src/fe-common/silc/module-formats.[ch].
1622 Sun May 19 18:59:00 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1624 * Fixed the CHANNEL_CHANGE notify handling in client libary
1625 to not use freed memory. Affected file is
1626 lib/silcclient/client_notify.c.
1628 * Fixed CUMODE_CHANGE notify handling in server. Affected
1629 file silcd/packet_receive.c.
1631 * Fixed USERS command to support empty channels. Affected
1632 file silcd/command.c.
1634 Sat May 18 11:35:19 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1636 * Allow multiple identical pending commands to be registered
1637 in client library. Affected file is lib/silcclient/command.c.
1639 * Call the completion for resolving client information only
1640 after all resolvers has finished. This fixes a crash in
1641 the client. Added support for checking when the resolvers
1642 are finished. Affected file is lib/silcclient/idlist.c.

2130 it to protocol specs and implemented it to client and server.
2131 Protocol TODO #13. Affected files are silcd/command.c,
2132 silcd/packet_receive.c, packet_send.[ch],
2133 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
2134 The killer's client entry is now returned to application in
2135 the `notify' client operation.
2137 * Fixed the Max Argument fields that had too large value set
2138 in the protocol specs. Protocol TODO #14.
2140 * Added the LEAVE command reply to return the ID of parted
2141 channel. Updated protocol specs and implemented it to the
2142 client and server. Protocol TODO #15. Affected files are
2143 silcd/command.c, lib/silcclient/command_reply.c. The channel
2144 entry is now returned to application in the `command_reply'
2147 * Rewrote the version SKE version checking in client libary
2148 and in server to use the silc_parse_version_string. Affected
2149 files are lib/silcclient/protocol.c, silcd/protocol.c.
2151 * Added SILC_STATUS_ERR_NO_CHANNEL_FOPRIV error status to few
2152 commands that was missing it, and updated protocol specs and
2153 the server implementation. Protocol TODO #10. The affected
2154 file is silcd/command.c.
2156 * Defined new message flags SILC_MESSAGE_FLAG_REPLY to be
2157 generic reply to a generic request (REQUEST flag), and
2158 SILC_MESSAGE_FLAG_DATA to send any kind of data in a generic
2159 way. A draft-riikonen-silc-flags-payloads-00.txt is written
2160 to define the payload for DATA flag. Added the flags to
2161 the implementation. Protocol TODO #9. Affected file is
2162 lib/silccore/silcchannel.h.
2164 Changed the client library to return the message length
2165 to application as well in the channel_message and private_message
2166 client operations. Affected files are
2167 lib/silcclient/client_prvmsg, lib/silcclient/client_channel.c,
2168 lib/silcclient/silcclient.h, irssi/src/silc/core/client_ops.c,
2169 and lib/silcclient/client_ops_example.c.
2171 * Added two new channel modes: SILC_CMODE_SILENCE_USERS
2172 and SILC_CMODE_SILENCE_OPERS which can be used to moderate
2173 the channel. Updated protocol specs and impelemented this
2174 to client and server. Protocol TODO #6. Affected files are
2175 silcd/packet_receive.c, server_util.c, lib/silcclient/command.c,
2176 lib/silcclient/client_channel.c, lib/silccore/silcmode.h.
2178 Added new options m and M to CMODE command in Irssi SILC
2179 client to set these modes.
2181 * Deprecated all administrative commands from SILC protocol
2182 since they are highly implementation specific commands.
2183 Updated protocol specs. Moved the old commands in
2184 implementations to private range of command types. Affected
2185 files are silcd/command.c, lib/silcclient/command.c and
2186 lib/silcclient/command_reply.c. Protocol TODO #8.
2188 * Fixed a bug in server where sending unknown command crashes
2189 the server. Affected file silcd/command.c.
2191 Wed Apr 3 09:57:47 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
2193 * Added SILC_PROTOCOLVERSION macro to check protocol version
2194 of a socket connection. The affected file is
2195 lib/silcutil/silcsockconn.h.
2197 * Added better error logging in rekey protocol. Affected file
2200 * Do not check public key types in SKE during rekey. Affected
2201 file lib/silcske/payload.c.
2203 * Fixed the rekey protocol with PFS, which was totally broken.
2204 Affected file silcd/protocol.c.
2206 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
2208 * Some client implementations quit network by doing first LEAVE
2209 and then immediately SIGNOFF (like Bombyx). We now do check
2210 after a short time after LEAVE notify and check whether the
2211 client is still valid after LEAVE, and if not we remove it from
2212 cache. Affected file is lib/silcclient/client_notify.c.
2214 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
2216 * Merged version 1.1.4 of zlib. Even if it not currently in use,
2217 it's good not to have security holes here.
2219 * Fixed a negative refcount situtuation for the config context.
2220 Affected file is silcd/serverconfig.c.
2222 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
2224 * ROBOdoc documented lib/silcutil/silcutil.h.
2226 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2228 * Optimized even more the SilcPacketContext structure. Now
2229 totally saved 16 bytes of memory per context after optimization.
2230 Affected files are lib/silccore/silcpacket.[ch].
2232 * Made strict checks for valid SILC IDs. Affected file is
2233 lib/silccore/silcid.c.
2235 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2237 * Changed the object argument for silc_cipher_register,
2238 silc_hash_register, silc_hmac_register and silc_pkcs_register
2239 to const. Affected files are lib/silccrypt/silccipher.[ch],
2240 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
2242 * Changed the silc_get_username and silc_get_real_name to
2243 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
2245 * Fixed the Irssi SILC Client to use the silc_get_username and
2246 silc_get_real_name insted of glib routines since the glib
2247 routines only corrupt stack. Fixes the Irssi SILC to work in
2248 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
2250 * Fixed the Irssi to not use g_get_home_dir since it crashes
2251 or returns garbage on cygwin and corrupts stack. Added function
2252 get_home_dir to Irssi routines. Affected files are
2253 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
2255 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2257 * Made some structure optimizations. SFTP memory FS MemFSEntry
2258 entry structure. Optimized SilcTask structure. Optimized
2259 SilcPacketContext structure.
2261 Affected files lib/silcsftp/sftp_fs_memory.c,
2262 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
2264 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2266 * And yet again reverted back the config thing since Johnny
2267 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
2270 * Fixed memory leaks from config object. Affected files are
2271 silcd/serverconfig.[ch].
2273 * Added support for adding new connections to the server in rehash.
2274 After rehash they take effect.
2276 Added support for changing the maximum allowed connections in
2277 rehash. The number can grow but going smaller is not supported.
2279 Added function silc_server_num_sockets_by_remote to the
2280 silcd/server_util.[ch].
2282 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
2284 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
2286 * Added preliminary checking during config parsing for a valid
2287 public/private key and removed further checks in the code.
2288 Affected files are silcd/serverconfig.[ch], server.c.
2290 * Moved functions silc_server_drop() and silc_server_daemonise()
2291 from server.c to silcd.c since they are stricly related to
2292 the application activity.
2294 * Reverted a small part of the automatic ref/unref since
2295 it caused a double unref in some situations. Affected
2296 files are silcd/silcd.[ch], server.c, serverconfig.c.
2298 * Added some .cvsignore files in the lib directory.
2300 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2302 * Fixed silc_net_gethostbyaddr to correctly resolve by
2303 address. Affected file lib/silcutil/silcnet.c.
2305 * Fixed the notify relaying to client. The HMAC to be used
2306 with relayed packets ws wrong and caused decryption failure
2307 at the client end. Affected file is silcd/packet_receive.c.
2309 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2311 * Created new branch silc_protocol_1_0_branch.
2313 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
2315 * Changed the silc_server_config_* routines to be SilcServer
2316 independent. They are now officially application specific code
2317 and not part of generic server implementation. Affected files
2318 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
2320 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2322 * Added automatic referencing of config context in the
2323 silc_server_config_alloc, and automatic unreferencing in the
2324 silc_server_config_destroy. Affected files are
2325 silcd/serverconfig.[ch], silcd/silcd.c.
2327 * Fixed the silc_log_quick handling in the logging routines.
2328 It didn't log quickly when it was TRUE. Affected file is
2329 lib/silcutil/silclog.c. Also the flush delay was set even
2330 if it was 0 in config file. Affected file is
2331 silcd/serverconfig.c.
2333 * Added support for changing key pair of the server in rehash.
2334 Affected file silcd/server.c.
2336 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2338 * Fixed the TOPIC_SET notify to not cras. It changed the topic
2339 too early, before getting the channel entry. Affected file
2340 is silcd/packet_receive.c.
2342 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
2344 * Added functions silc_server_config_[ref/unref], these are used
2345 to prevent that the config object is destroyed.
2347 No longer directly affect global variables silc_log_quick and
2348 silc_log_delay, they are first cached inside the config object
2349 and then applied with silc_server_config_setlogfiles().
2351 silc_server_config_set_defaults() is now internal to
2352 serverconfig.c, there are no reasons to show this internal stuff
2355 Affected files are silcd/serverconfig.[ch].
2357 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
2358 fprintf's to stderr, since some code may be executed again after
2359 the server went into the background. Affected files are
2362 * Added rehash support. Added function silc_server_rehash() that
2363 will perform all the basic tasks of the rehashing procedure.
2365 * Added command line option `-x, --hexdump'. This will enable the
2366 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
2367 The option `--hexdump' implies `--debug'.
2369 * Fixed a bad bug in the logging APIs (silcutil library) where
2370 the application would crash after calling silc_log_reset_all().
2372 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2374 * Fixed the KICKED notify handling in client library to
2375 correctly remove the channel and all entries from the
2376 channel when I was kicked. This bug crashed the client.
2378 Fixed yet another but in KICKED notify handling to remove
2379 the kicked client correctly from the channel.
2381 Affected file is lib/silcclient/client_notify.c.
2383 * Fixed a minor bug in looking up correct client entry
2384 in KICKED notify in server. Affected file is
2385 silcd/packet_receive.c.
2387 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
2388 sources correctly to distribution. Fixes --with-gmp option.
2390 * Removed the manual rehashing from ID Cache, and changed it
2391 to use the SILC Hash Table's auto rehash feature. Affected
2392 file is lib/silccore/silcidcache.c.
2394 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2396 * Fixed a bug in the silc_client_nickname_format function that
2397 handles the multiple same nickname formatting. Two clients
2398 with same nickname caused problems after the first one left
2399 and rejoined. It didn't format the nickname correctly.
2400 Affected file is lib/silcclient/idlist.c.
2402 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2404 * Don't change the topic if olod topic is same as new one.
2405 Affected file is silcd/packet_receive.c.
2407 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2409 * Added cross-reference support to the SILC Documentation
2410 generator. All types across all HTML files are now cross-
2411 referenced. Affected files util/robodoc/generator.c and
2412 scripts/silcdoc/silcdoc.
2414 * Added file lib/silcutil/silctypes.h to include all the
2415 arithmetic type definitions and some macros. Removed
2416 includes/bitmove.h and moved macros to silctypes.h.
2418 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2420 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
2422 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2424 * Added `type' argument to silc_id_payload_parse_id function which
2425 now returns the type of the ID to the sent pointer. Affected
2426 file is lib/silccore/silcid.[ch].
2428 * Added check for CMODE_CHANGE notify type that mode change is
2429 allowed by the sender. Affected file silcd/packet_receive.c.
2431 * Added check for CUMODE_CHANGE notify type that mode change is
2432 allowed by the sender. Affected file silcd/packet_receive.c.
2433 Added the ID type as CUMODE_CHANGE notify type as argument
2434 to the `notify' client operation. Affected files are
2435 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
2437 * Added function silc_client_add_server to the client library.
2438 Added support for resolving also channel and server info when
2439 received unknown entity in notify packet. Affected files are
2440 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
2442 * Added function silc_command_get_status to return the command
2443 status from the command reply's argument payload. Affected files
2444 are lib/silccore/silccommand.[ch].
2446 * Added check for KICKED notify type that the kicking is
2447 allowed by the client. Affected file silcd/packet_receive.c.
2449 * Created function silc_get_input which can be used to get input
2450 (echo on or off) from user on command line. Affected files are
2451 lib/silcutil/silcutil.[ch].
2453 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2455 * Optimized silc_server_packet_relay_to_channel function.
2456 Added new function silc_channel_message_payload_encrypt which
2457 can be called directly if channel message payload needs to
2458 be encrypted and is already encoded (no need to call _encode
2459 function). Packet relaying is now done by router without any
2460 extra memory allocations. Affected files are
2461 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
2462 silcd/packet_send.c.
2464 * Fixed the INVITE notify handling. It took wrong arguments
2465 as invite list and invite delete. Affected file is
2466 silcd/packet_receive.c.
2468 * Added check for TOPIC_SET notify type that the topic change is
2469 allowed by the client. Affected file silcd/packet_receive.c.
2471 * Added check for INVITE notify type that inviting is allowed by
2472 the client. Affected file silcd/packet_receive.c.
2474 * Changed the silc_server_client_on_channel to return the
2475 SilcChannelClientEntry as well. Moved the function
2476 silc_server_check_cmode_rights to server_util.[ch].
2477 Affected files are silcd/server_util.[ch], silcd/command.c.
2479 * Added function silc_server_check_umode_rights to check whether
2480 changing client's user mode is allowed. Added check for
2481 UMODE_CHANGE notify type that the umode change is allowed
2482 by the client. Affected files are silcd/server_util.[ch],
2483 silcd/packet_receive.c and silcd/command.c.
2485 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2487 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
2488 ID length. It ignored that ID can be IPv6 based as well.
2489 Affected file lib/silccore/silcpacket.h.
2491 * Fixed the silc_id_id2str and silc_id_str2id to take the
2492 IPv6 address offset's into consideration. Affecte file is
2493 lib/silccore/silcid.c.
2495 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2497 * Fixed the internal Unix scheduler functions to check for
2498 NULL context they may receive. The affected file is
2499 lib/silcutil/unix/silcunixschedule.c.
2501 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
2503 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
2504 can specify different directory with --home command line
2505 parameter. Affected files irssi/src/silc/core/client_ops.c,
2508 * SILC-specific commands aren't now executed if the active server
2509 isn't of SILC-type, so there won't be problems with having
2510 IRC and SILC protocol support in same client. Affected files
2511 irssi/src/silc/core/silc-channels.c, silc-servers.c,
2514 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2516 * Improved the signal support in SILC Schedule. Added new
2517 function silc_schedule_signal_call which is used by application
2518 to mark a signal to be called. It is now safe to perform
2519 any kind of tasks in signal callbacks since it is guaranteed
2520 that the application specified signal callback is called
2521 after the signal is over. Affected files are
2522 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
2524 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2526 * Added `name' field to SilcChannelPrivateKey to represent
2527 application given name for the key. Moved also the context from
2528 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
2529 Added the `name' argument also to the function
2530 silc_client_add_channel_private_key.
2532 Added function silc_client_current_channel_private_key to set the
2533 current channel private key in use.
2535 Added "change" command to KEY command which can be used to change
2536 the current channel private key. Bound the command also to
2537 alt+K (Alt+Shift+k).
2539 Also affected files lib/silcclient/client_channel.c,
2540 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
2542 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2544 * Added silc_rng_get_byte_fast function in to the
2545 lib/silccrypt/silcrng.[ch].
2547 * Changed the interface of silc_packet_assemble and the
2548 silc_packet_send_prepare. If silc_packet_assmble is now
2549 called the application does not call silc_packet_send_prepare
2550 because the library will call it automatically. These
2551 interfaces now also return a reference to the outgoing buffer
2552 which includes the assembled packet, which the application can
2553 use to encrypt the packet.
2555 Affected files are lib/silccore/silcpacket.[ch],
2556 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
2557 silcd/packet_send.c, server_backup.c and packet_receive.c.
2559 * Fixed a packet sending bug on very high load, where outgoing
2560 packet queue wasn't handled correctly and packets got corrupted.
2561 Affected files are lib/silcutil/*/silc*sockconn.c,
2562 lib/silcclient/client.c and silcd/server.c.
2564 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2566 * Added macro SILC_PACKET_DATALEN which can be used during
2567 packet assembling to check whether the data to be added to
2568 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
2569 len is truncated until it fits it.
2571 Added checks for maximum length of channel message payload and
2572 private message payload also.
2574 Added checks for maximum packet length in server and in
2577 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
2578 lib/silcclient/client.c, lib/silccore/silcchannel.c and
2579 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
2580 lib/silcclient/client_prvmsg.c.
2582 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2584 * Added silc_server_packet_queue_purge call to the
2585 silc_server_disconnect_remote to assure that all data in the
2586 queue before disconnecting is sent to the network. Affected
2587 file silcd/server.c.
2589 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2591 * Added the deleting of server's own ID cache entry to the
2592 silc_server_free function. Free also everything else that
2593 has been allocated in silc_server_init. The affected file
2596 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2598 * Added functions silc_parse_version_string, silc_version_to_num,
2599 and silc_ske_parse_version to parse SILC protocol style version
2600 strings. Affected files lib/silcutil/silcutil.[ch] and
2601 lib/silcske/silcske.[ch].
2603 * Added new configuration params: version_protocol, version_software
2604 and version_software_vendor to specify what version the remote
2605 host must at least be to be able to connect to server. The vendor
2606 string can be regex matched too. Added new function
2607 silc_server_connection_allowed to check maximum number of allowed
2608 connections, and allowed versions for incoming connections.
2609 Affected files are silcd/server.c, server_util.[ch] and
2612 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2614 * Added preliminary support for signals in scheduler. The
2615 signals we care about are now blocked always when the scheduler
2616 is locked. This way we can synchronise the use of signal with
2617 scheduler. It is guaranteed that when signal occurs the scheduler
2618 is not locked, and thus new tasks can be safely added to the
2621 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
2622 to silc_schedule_internal_init and silc_schedule_internal_uninit.
2623 Added new platform specific routines
2624 silc_schedule_internal_signals_[un]block and
2625 silc_schedule_internal_signal_[un]register.
2627 Added new functions to SILC Schedule API:
2628 silc_schedule_signal_[un]register. Each signal that application
2629 is going to use should be registered to the scheduler.
2631 Affected files are lib/silcutil/silcschedule.[ch],
2632 lib/silcutil/*/silc*schedule.c.
2634 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2636 * Check for unauthenticated client and server in the
2637 silc_server_new_client and silc_server_new_server functions.
2638 Affected file silcd/packet_receive.c.

2641 string is 7-bit ASCII string. Affected files are
2642 lib/silcutil/silcutil.[ch].
2644 * Added function silc_id_is_valid_server_id into the
2645 silcd/serverid.c and added checking for valid Server ID's in
2646 silc_server_new_server. The Server ID must always be based
2647 on the server's public IP address.
2649 * Added logging of DISCONNECT packet message in the server.
2650 Affected file silcd/server.c.
2652 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2654 * Changed all library interfaces that use Global RNG to also
2655 accept SilcRng as argument. Affected files are
2656 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
2657 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
2658 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
2659 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
2660 lib/silccrypt/rsa.c.
2662 * Added function silc_pkcs_generate_key to the
2663 lib/silccrypt/silcpkcs.[ch] for applications so that they
2664 don't need to do pkcs->pkcs->init calls anymore.
2666 * Remove SilcSocketConnection from the SFTP API since it really
2667 wasn't needed there. The application has the information
2668 saved in its contexts anyway and the SFTP layer doesn't need
2669 know about it. Affected files lib/silcsft/silcsftp.h and
2670 lib/silcsftp/sftp_[server/client].c.
2672 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].

2676 lib/silcutil/silcutil.c.
2678 * On EPOC the global crypto module lists are not used at all
2679 in the crypto library. Added support for using the constant
2680 algorithm list on EPOC. Affected files are
2681 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
2684 * Fixed the handling of third parameter of KICKED notify, since
2685 it was mistakenly updated to SILC Protocol 1.0 even though it
2686 is to be included in 1.1. Since it is not in 1.0 it is not
2687 mandatory, and this fix now handles it only if it is provided,
2688 and it is not error if it is not provided. Affected file
2689 lib/silcclient/client_notify.c.
2691 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>

2698 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2700 * Check for valid socket connection in client entries before
2701 sending any messages. Fixes a crash, but doesn't fix some
2702 other underlaying bug that is lurking there. Affected
2703 file silcd/packet_send.c.
2705 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
2707 * $usermode, $cumode and $cumode_space expandos shouldn't do
2708 anything with non-SILC server records. Affected file
2709 irssi/src/silc/core/silc-expandos.c
2711 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2713 * Fixed the silc_net_check_[host/local]_by_sock to support
2714 IPv6 bound sockets as well. Now they can return IPv6 addresses
2715 as well. Affected file lib/silcutil/silcnet.c.
2717 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
2718 Affected lib/silcutil/unix/silcunixnet.c.
2720 * Fixed ID rendering (at least on some platforms, not NetBSD)
2721 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
2723 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2725 * Added silc_hash_public_key and silc_hash_public_key_compare
2726 functions to be used with SilcHashTable. They can be used to
2727 hash public keys and compare public keys in hash table. Affected
2728 file lib/silcutil/silcutil.[ch].
2730 * Added support for specifying multiple public keys for Client
2731 connection section in server configuration file. This makes it
2732 possible to accept multiple public keys from same host, or to
2733 make a section that accepts any incoming host, and have the
2734 accepted public keys listed in the section.
2736 Added functions silc_sever_[find/get]_public_key, added the
2737 support for this actually to all connection sections but only
2738 the Client section is currently allowed to specify multiple
2741 Affected files are silcd/server.c, server_internal.h,
2742 command.c, protocol.c, server_util.[ch], packet_receive.c.

2748 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
2750 * If silc_debug is TRUE, also output standard logging messages
2751 to stderr with the debug output.
2753 Made silc_log_reset_all() flushing all channels before returning.
2754 Also fixed some documentation typos.
2756 Affected files are lib/silcutil/silclog.[ch].
2758 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2760 * Fixed the server to check correctly the amount of connections
2761 from single host, by checking also the type of the connection.
2762 Fixed also the comparison of number of connections and number
2763 of allowed connections. Affected files are silcd/server.c,
2766 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2768 * Fixed the USERS command reply to save the user's mode on the
2769 channel as well. Fixed JOIN command reply to check whether a
2770 client is on channel already and not join it twice. Affected
2771 file lib/silcclient/command_reply.c.
2773 * Added new file silc-expandos.c into irssi/silc/core/ to return
2774 various stuff for various signal for the statusbar etc. updating.
2775 Now Irssi SILC client prints channel user modes etc. on the
2778 * The user mode (like server/router operator changes) is now shown
2779 on the Irssi SILC client's statusbar. The affected files are
2780 irssi/src/silc/core/client_ops.c, silc-expandos.c.
2782 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2784 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c

2818 * Changed all integer type names:
2819 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
2820 to avoid collisions with other libraries using same type names
2823 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2825 * Added `prefer_ipv6' argument to the functions
2826 silc_net_gethostbyname[_async]. If it is TRUE it will return
2827 IPv6 address over IPv4. If FALSE IPv4 address is returned
2828 even if IPv6 address was found. Affected files
2829 lib/silcutil/silcnet.[ch].
2831 * Added support silc_net_create_connection[_async] to fallback
2832 to IPv4 address if IPv6 address could not be used (like if

2842 Wed Feb 20 20:41:01 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2844 * Added automatic extern "C" { ... } for C++ compilers so the
2845 application does not need to define them. Affected file
2846 includes/silcincludes.h.
2848 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
2849 old name went against naming convention. Applications now
2850 include "silcclient.h" instead of "clientlibincludes.h".
2851 Removed includes/clientlibincludes.h, it is redundant now.
2853 * Renamed includes/version.h to silcversion.h.
2855 * Added really preliminary support for OS/2 into the util
2856 library. Only thread & mutex API is implemented, others
2857 are still to be implemented. Created the lib/silcutil/os2/
2858 directory. Created also file includes/silcos2.h.

2891 * Added `user_count' to the SilcChannelEntry which now tells the
2892 number of users on the channel. The user count is now saved
2893 in normal server of global channels as well. Affected files
2894 silcd/server.c, idlist.h, packet_receive.c and command.c.
2896 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
2897 include file utility functions.
2899 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
2900 instead of calling directly OS routines.
2902 * Fixed NICK change printing in Irssi SILC Client. Fixed
2903 KICKED notify printing in Irssi SILC Client. Affected file
2904 irssi/src/silc/core/client_ops.c.

2907 client_entry->channels hash table everytime nick is changed.
2908 Affected file lib/silcclient/client.c.
2910 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2912 * ROBOdoc documented the lib/silcske/silcske.h, and improved
2913 the SKE interface a bit.
2915 * Fixed padding problem in PKCS#1. The padding was not actually
2916 random since the random number generator was used incorrectly.
2917 This security bug affects only when encrypting with PKCS#1, and
2918 it is not currently used at all in SILC. SILC only use signing
2919 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
2921 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>

2933 key_exchange_timeout, conn_auth_timeout, connections_max,
2936 Implemented all the new config settings handling in the server.
2938 Optimized the use of SKE Mutual flag usage. Use it only
2939 if connection authentication protocol is not based in public
2942 Renamed all SilcServerConfigSection* to SilcServerConfig*
2943 to have a bit shorter names.
2945 Affected files silcd/serverconfig.[ch], server.[ch], and

2979 is now done in silc_core_init() which also fixes autoconnecting
2982 Affected files irssi/src/silc/core/silc-core.c,
2983 irssi/src/fe-text/silc.c.
2985 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2987 * Added new configuration options and blocks:
2988 keepalive_secs, reconnect_count, reconnect_interval,
2989 reconnect_interval_max, reconnect_keep_trying and
2990 require_reverser_lookup. Added ConnectionParam block, and
2991 implemented the connection parameters when connecting as
2992 initiator and when accepting connections as responder.
2994 Added CONFIG_IS_DOUBLE macro in config file parsing, to check
2995 whether given configuration value has been given already.
2997 Affected files silcd/serverconfig.[c], server.[c].
2999 * Splitted the doc/example_silcd.conf.in. Separated the crypto
3000 algorithm parts and created new file silcalgs.conf, that
3001 is now included from the example_silcd.conf.in.
3003 * Optimized the silc_server_connect_to_router_second to take
3004 the connection configuration object from the SilcServerConnection
3005 object instead of finding it during the connecting phase.
3006 Added the configuration object to SilcServerConnection struct.
3007 Affected files silcd/server_internal.h, server.c.
3009 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
3011 * Add the client on channel after it was resolved at the
3012 channel message receiving, and it was not already on the
3013 channel. Affected file lib/silcclient/client_channel.c.
3015 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>

3030 config file, allowing both public key and passphrase based
3031 authentication to be set at the same time.
3033 Added `prefer_passphrase_auth' setting in config file which
3034 can be used to set to prefer passwd auth if both passwd and
3035 public key is set. If not set, public key is preferred.
3036 This has effect only when being initiator (responder will try
3039 Added support for authentication with passphrase and public key
3040 at the same time. The passphrase is tried first always since
3041 it is faster to check.
3043 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
3045 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

3091 * Fixed the file transfer's key agreement payload to include
3092 zero port also if the hostname is NULL because it could not
3095 Call file transfer monitor callback now also if error occurs
3096 during key agreement protocol.
3098 Changed the silc_client_file_send interface to return the
3099 SilcClientFileError instead of session id. The session ID
3100 is returned into pointer provided as argument.

3117 file lib/silcutil/silclog.c.
3119 * Fixed the channel message payload decryption in the function
3120 silc_channel_message_payload_decrypt to not modify the original
3121 buffer before it is verified that the message decrypted
3122 correctly. Otherwise, next time it is called with correct
3123 channel key it won't encrypt since the payload is corrupted.
3124 Affected file lib/silccore/silcchannel.c.
3126 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

3140 become invalid in the callback but it was referenced after
3141 the callback returned.
3143 Do not allow auto rehashing of hash table during the
3144 silc_hash_table_foreach operation, for same reasons as it is
3145 not allowed for SilcHashTableList. Affected files are
3146 lib/silcutil/silchashtable.[ch].
3148 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
3150 * Defined DLLAPI into silcincludes.h and silcwin32.h for
3151 Win32 DLL. extern's in header files are now declared with
3154 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
3156 * Fixed private message handling. It used some old code that
3157 caused the client to crash. Affecte file is
3158 lib/silcclient/client_prvmsg.c.
3160 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
3162 * Added function silc_client_add_channel,
3163 silc_client_replace_channel_id, and removed functions
3164 silc_client_new_channel_id and silc_idlist_get_channel_by_id
3165 from client library.
3167 * Added cross reference of the joined channels to the
3168 SilcClientEntry, and changed the SilcChannelEntry's
3169 users list to SilcHashTable. The affected files are
3170 lib/silcclient/idlist.[ch].
3172 * Fixed a bug in hash table tarversing. While the hash table
3173 is traversed with SilcHashTableList the table must not be
3174 rehashed. It is now guaranteed that auto rehashable tables
3175 are not rehashed while tarversing the list. Also defined that
3176 silc_hash_table_rehash must not be called while tarversing
3177 the table. Added function silc_hash_table_list_reset that must
3178 be called after the tarversing is over. The affected files are
3179 lib/silcutil/silchashtable.[ch].
3181 * Changed all hash table traversing to call the new
3182 silc_hash_table_list_reset in server and in client library.
3184 * Added function silc_client_on_channel to return the
3185 SilcChannelUser entry if the specified client entry is joined
3186 on the specified channel. This is exported to application as
3187 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
3189 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
3191 * Fixed founder regaining problem with JOIN command on normal
3192 server. The notify for mode change must be sent always and
3193 not only if !cmd->pending. Affected file silcd/command.c.
3195 * Fixed the WHOWAS command's reply sending to support the
3196 lists correctly. Affected file silcd/command.c.
3198 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
3200 * When sending JOIN command to router for processing the
3201 sender's old command identifier was not saved back to the
3202 sender's command context, fixed now. The affected file is
3205 * Create the key in JOIN command of the router did not return
3206 the channel key, added check for this. Affected file is
3209 * Fixed a channel ID update bug in JOIN command reply. Do
3210 not directly upgrade the ID but call the function
3211 silc_idlist_replace_channel_id if the ID was changed.
3212 Affected file silcd/command_reply.c.
3214 * Fixed memory leaks from command calling if it would fail.
3215 Affected file silcd/command.c.
3217 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
3219 * Applied patches from cras:
3221 Memory leak fixes around libaries, irssi window resize fix,
3222 new silclist.h and silcdlist.h, all extern inline changed to
3225 * Removed dotconf from lib/dotconf, not needed anymore.
3227 * Removed TRQ from lib/trq, not needed anymore.
3229 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
3230 with server connections. Later this will be configurable
3231 in config file after new config file is done. Affected file
3234 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
3236 * Fixed a crash in server related to channel announcements.
3237 Affected file silcd/server.c.
3239 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
3241 * Fixed memory leaks in silc_server_create_new_channel*
3242 functions. Affected file silcd/server.c.
3244 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
3245 which ID was changed. This way the router will send the
3246 user list for the channel again, and server won't be in
3247 desync in some rare circumstances. Affected file is
3248 silcd/packet_receive.c.
3250 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
3252 * Check for NULL socket pointer in the function
3253 silc_server_packet_send_to_channel_real. Affected file
3254 silcd/packet_send.c.
3256 * Fixed the BAN notify handling to correctly remove ban
3257 list. Affected file silcd/packet_receive.c.
3259 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
3261 * Fixed some header addition to Toolkit distribution in
3262 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
3264 * Added lib/silcclient/client_ops_example.h as an template
3265 file for application programmers to quickly start using
3266 the SilcClientOperation functions in their application.
3267 Updated the lib/silcclient/README as well to tell about this
3268 nice file made available.
3270 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
3272 * Call silc_server_remove_from_channels when removing client
3273 entry when NO_SUCH_CLIENT_ID was received. Affected file
3274 is silcd/command_reply.c.
3276 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
3278 * Added server & router operator statistics updating. Affected
3279 file silcd/packet_receive.c and silcd/command.c.
3281 * Fixed the SERVER_SIGNOFF notify handling on normal server
3282 not to save the history information for clients. Same was
3283 fixed earlier in remove_clients_by_server function, but not
3284 here. Affected file silcd/packet_receive.c.
3286 * Raised the default connection-retry count from 4 to 7 in
3287 server. Affected file silcd/server.h.
3289 * Cancel any possible reconnect timeouts when we start the
3290 key exchange. Affected file silcd/server.c.
3292 * Do not reconnect on connection failure when SCONNECT was
3293 given. Affected files silcd/server.[ch].
3295 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
3297 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
3299 * Fixed the NICK command to always give the unformatted
3300 nickname to the one giving the NICK command. If unformatted
3301 nickname is cached already it will be formatted and the
3302 local entry will always get the unformatted nickname.
3303 Affected file lib/silcclient/idlist.c.
3305 * Fixed some double frees from client library commands.
3306 Affected file is lib/silcclient/command.c.
3308 * Fixed CUMODE command in server to assure that no one can
3309 change founder's mode than the founder itself, there was a
3310 little bug. Affected file silcd/command.c.
3312 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
3314 * Removed the SilcClientCommandDestructor from the client
3315 libary, it is not needed anymore. Affected files are
3316 lib/silcclient/silcapi.h, command[_reply].[ch],
3317 client_notify, idlist.c.
3319 * Fixed GETKEY command to first resolve client, and then
3320 resolve the server only if the client was not found, instead
3321 of resolving both at the same time. Affected file is
3322 lib/silcclient/command.c.
3324 * Added silc_client_start_key_exchange_cb and lookup the
3325 remote hostname and IP address before starting the key
3326 exchange with server. The affected file is
3327 lib/silcclient/client.c.
3329 * The server's public key is now saved using the IP address
3330 of the server and not the servername for the filename.
3331 The hostname public key filename is checked as an fall back
3332 method if the IP address based filename is not found.
3334 Fixed the GETKEY command to save the fetched server key
3335 in correct filename.
3337 Print the remote server's hostname now when new key is
3338 received during connection process. Affected file is
3339 irssi/src/silc/core/client_ops.c.
3341 * Return always our own public key to the client if it asks
3342 for it with GETKEY command. Affected file silcd/command.c.
3344 * Removed the use_auto_addr variable from default config
3345 file since it was in wrong section. Affected file is
3348 * Fixed TOPIC_CHANGE notification to not route it when it
3349 was sent using silc_server_send_notify_to_channel function.
3350 Affected file silcd/command.c.
3352 * Fixed silc_server_send_notify_kicked to send the kicker's
3353 Client ID also, it was missing. Affected files are
3354 silcd/command.c, silcd/packet_send.[ch].
3356 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
3358 * Do not save client history information in SERVER_SIGNOFF.
3359 Fixes the bug in normal server that it does not detect
3360 the client becoming valid after the server becomes back
3361 online. Affected file silcd/server_util.c.
3363 * Added `sock_error' field into the SilcSocketConnection
3364 context. When error occurs during socket operation (read
3365 or write) the error is saved. Added also new function
3366 silc_socket_get_error to return human readable socket error
3367 message. Affected files are lib/silcutil/silcsockconn.[ch],
3368 lib/silcutil/unix/silcunixsockconn.c, and
3369 lib/silcutil/win32/silcwin32sockconn.c.
3371 * The server now prints the socket error message in the
3372 signoff for client. Affected file silcd/server.c.
3374 * Fixed the `created' channel information sending from router
3375 to server in JOIN command. Checks now whether the channel
3376 really was created or not and set it according that.
3378 Fixed the JOIN command to use the client entry's current
3379 ID during the joining procedure instead of the one it sent
3380 in the command (it is checked though), since it can change
3381 between the packet processing and command processing, and
3382 would just case unnecessary pain in the client end. Affected
3383 file silcd/command.c.
3385 * Fixed a channel key payload sending to use correct channel
3386 ID when the server was forced to change the channel's ID by
3387 router. Router sent the key payload with the old Channel ID.
3388 Affected file silcd/packet_receive.c.
3390 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
3392 * Call silc_server_save_channel_key only if the key payload
3393 was provided in the JOIN command's command reply. Affected
3394 file silcd/command_reply.c.
3396 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
3398 * Fixed silc_mp_sizeinbase to return the value correctly with
3399 MPI. Affected file lib/silcmath/mp_mpi.c.
3401 * Fixed the stop_server signal to correctly stop the scheduler
3402 and gracefully stop the server when SIGTERM or SIGINT signals
3403 are received. Affected file silcd/silcd.c.
3405 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
3407 * Simple handling of TERM and HUP signals. Also added some log
3408 flushing call around. Affected file is
3411 * Fixed small bugs in silclog.c. Now buffering output will take
3412 effect after 10 seconds since startup: This will ensure that
3413 no important startup messages are lost. Also output redirection
3414 will preserve original format ([Date] [Type] message).
3415 Affected file is lib/silcutil/silclog.c.
3417 * Added two options to the config file, in the logging section:
3418 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
3419 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
3421 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
3423 * Do not print the warning about log files not being initialized
3424 more than once to avoid excess logging. Affected file is
3425 lib/silcutil/silclog.c.
3427 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
3428 the SIM copying in make install in Makefile.am.pre.
3430 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
3432 * Rewritten silclog APIs. Globally interesting changes follows:
3433 silc_log_set_files() changed to silc_log_set_file().
3434 silc_log_set_callbacks() changed to silc_log_set_callback().
3435 ROBOdoc documented silclog header file.
3436 SilcLogCb now returns bool to wether inihibit the default
3437 handler or not (to keep the old behaviour return always TRUE).
3438 The new APIs should also fix the problem of the
3439 silcd_error.log file that was written in the current directory.
3442 Log files streams will remain opened after silc_log_set_file()
3443 call, means less CPU usage notably on high traffic servers.
3444 File streams are now full buffered, and flushed to the disk
3445 every 5 minutes, lesses HD activity and CPU usage.
3446 Messages can be redirected, allowing admins to configure
3447 one single logfile for all server messages.
3448 the silc_log_quick global variable to activate fast-logging.
3449 Affected files lib/silcutil/silclog.[ch]
3451 * Changed some code to conform new silclog APIs. Affected
3452 files are doc/example_silcd.conf.in, silcd/server.c
3453 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
3456 * Fixed a memory leak that could occur in some situations.
3457 Affected file silcd/serverconfig.c.
3459 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
3461 * Added the silc_client_del_client to remove the client from
3462 all channels as well. Affected file lib/silcclient/idlist.c.
3464 * Fixed the client library to correctly remove the client
3465 from all channels when the client entry is being destroyed.
3466 Affected file lib/silcclient/client_notify.c, command.c.
3468 * Added auto-nicking support to the client library. If the
3469 applicatio now sets client->nickname it will be sent to the
3470 server after connecting by the library. This way for example
3471 SILCNICK (or IRCNICK) environment variables will have effect
3472 and always change the nickname automatically to whatever
3473 it is wanted. Affected file lib/silcclient/client.[ch].
3475 * Renamed silc_server_command_bad_chars to the
3476 silc_server_name_bad_chars and moved it to the
3477 silcd/server_util.[ch]. Added also new function
3478 silc_server_name_modify_bad to return nickname that
3479 includes bad characters as new nickname without those
3480 bad characters. This check and modify is now used in
3481 silc_server_new_client when the username is initially set
3482 as nickname, so it must be checked to be valid nickname.
3483 Affected file silcd/packet_receive.c.
3485 * The nickname length is now taken from the packet for real
3486 and not trusted to strlen() since it clearly can return
3487 wrong length for nickname including bad characters. This
3488 also applies to channel names. Affected file silcd/command.c.
3490 * Removed the lib/silcsilm/modules directory. Modules are now
3491 compiled into the lib/silcsim. Fixed the copying of the
3492 modules to follow symbolic links in Makefile.am.pre.
3494 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
3496 * Fixed silc_string_regexify list creation. Fixes bugs with
3497 BAN and INVITE commands in server. The affected file is
3498 lib/silcutil/unix/silcunixutil.c.
3500 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3502 * Removed the command destructor entirely from the server's
3503 command and command reply routines. It is not needed, and
3504 its usage was buggy and caused crashes. Affected files are
3505 silcd/command[_reply].[ch].
3507 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3509 * Cancel protocol and NULL sock->protocol if timeout
3510 occurred during protocol. Affected file silcd/server.c.
3512 * Cancel protocol timeouts always before calling the final
3513 callback, to assure that after final callback is called
3514 no other state will be called for the protocol anymore.
3515 Affected file silcd/protocol.c.
3517 * Print error log if incoming connection configuration could
3518 not be found. Affected file silcd/server.c.
3520 * Fixed JOIN command to correctly save the founder mode
3521 to the client on normal SILC server, when the channel
3522 was created by the router. Affected file silcd/command.c.
3524 * Fixed LIST command (hopefully) to send correct reply
3525 packets. Affected file silcd/command.c.
3527 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
3529 * The silc_packet_receive_process now returns FALSE if the
3530 read data was invalid packet, and TRUE if it was ok.
3532 The server now checks that if unauthenticated connection
3533 sends data and its processing fails the server will close
3534 the connection since it could be a malicious flooder.
3536 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
3538 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3540 * Make sure the warning about error opening a log file is
3541 printed only once and not everytime it fails (produces
3542 too much useless log). Affected file lib/silcutil/silclog.c.
3544 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
3546 * Made the silc_server_daemonise() function more readable.
3547 Affected file silcd/server.c.
3549 * Pid file is now optional, the user may comment it out from
3550 the config file. Removed define SILC_SERVER_PID_FILE, we
3551 don't need a default any longer. Affected file
3552 configure.in.pre, lib/Makefile.am.pre.
3554 * Make some use of the pid file. The server now dies at startup
3555 if it detects a valid pid file on his path. The server would
3556 die anyway in this circumstance, because of the bind() failure.
3557 Affected file silcd/silcd.c.
3559 * No longer compiling lib/dotconf.
3561 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3563 * Fixed JOIN command parsing not to crash. Affected file
3564 lib/silcclient/command.c.
3566 * Fied the NICK_CHANGE notify to add the new client entry
3567 even it is resolved. This removes an <[unknown]> nick
3568 thingy bug in the client. Affected file is
3569 lib/silcclient/client_notify.c.
3571 * Do not try to allocate 0 bytes (efence does not like it)
3572 in lib/silccore/silccomand.c when encoding payload.
3574 * Do not take IRCNICK as nickname in Irssi SILC client since
3575 it is not possible to set nickname before hand connecting
3576 the server (TODO has an entry about adding auto-nicking
3579 * Changed the silc_server_command_pending to check whether
3580 there already exists an pending entry with the specified
3581 command, command identifier and pending callback. This is
3582 to fix IDENTIFY and WHOIS related crashes that may register
3583 multiple pending commands with same identifier. Affected
3584 file silcd/command.c.
3586 * Fixed the server to reconnect to the router even if it
3587 was already reconnecting and EOF was received. This to
3588 fix a possibility that the server wouldn't ever try to
3589 auto-reconnect to the router. Affected file silcd/server.c.
3591 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3593 * Fixed the server's password authentication to use the
3594 length of the locally saved password, and not the one
3595 sent in the packet. Affected file silcd/protocol.c.
3597 * Fixed same password authentication problem in the
3598 Authentication Payload handling routines in
3599 lib/silccore/silcauth.c.
3601 * Yet another password authentication problem fixed with
3602 channel password handling in silcd/command.c.
3604 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3606 * If first character of string in silc_parse_userfqdn is '@'
3607 then do not parse it. Affected file is
3608 lib/silcutil/silcutil.c.
3610 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3612 * Fixed minor bug in IDENTIFY command reply sending, which
3613 caused various weird problems during JOIN when it was
3614 resolving names for users. Affected file silcd/command.c.
3616 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3618 * Fixed the IDENTIFY command reply sending to chech better valid
3619 clients. It was possible to send incomplete list of replies.
3620 Affected file silcd/command.c.
3622 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3624 * Added silc_client_command[s]_[un]register functions now to
3625 dynamically register the commands in client library. Removed
3626 the static table of commands. This allows the client library
3627 to call commands without causing the application to know about
3628 what commands library has called.
3630 Removed the INFO command reply kludge to detect when the command
3631 was called by library. Now library use its own command reply
3632 function for INFO command.
3634 Added function silc_client_command_call to call a command.
3635 Application can use it to call command, not access the structure
3638 Now all commands that are sent by the client library (not
3639 explicitly sent by application) use own command reply functions.
3641 Affected files around lib/silcclient/ and in
3642 irssi/src/silc/core/.
3644 * Fixed the WHOIS command reply sending to chech better valid
3645 clients. It was possible to send incomplete list of replies.
3647 Fixed the WHOIS and IDENTIFY to send the request to router
3648 if normal server did not do it and did not find any results.
3650 Affected file silcd/command.c.
3652 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3654 * Moved the internal data from SilcClient context into its
3655 own file, not accesible to application. Affected files
3656 lib/silcclient/client.h and lib/silcclient/client_internal.h,
3657 and other files in client library.
3659 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3661 * Added doc/examples installation target in Makefile.am.pre.
3664 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3666 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
3667 commands the found client entry will be removed from the
3668 cache, after notifying application about the error. Affected
3669 file lib/silcclient/command_reply.c.
3671 * Changed the /MSG to check for exact nickname user gave, and
3672 not let `nick' match `nick@host' if it is only one found. Now,
3673 user must type the exact nickname (like nick@host2) even if
3674 there are no more than one same nicks found. This is to avoid
3675 a possibility of sending nickname to wrong nickname since
3676 `nick' could match `nick@host'. Affected file is
3677 irssi/src/core/silc-servers.c.
3679 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3681 * Do not print "you are now server operator" or similar when
3682 giving /away command. Affected files are
3683 irssi/src/silc/core/client_ops.c, silc-servers.h.
3685 * Made the silc_server_command_pending_error_check to send
3686 the same command reply payload it received back to the
3687 original sender of the command. This way all arguments
3688 that was received by the server will be received by the
3689 client too. Affected file silcd/command.c.
3691 * Added the silc_idcache_add to return the created cache entry
3692 to a pointer. Affected file lib/silccore/silcidcache.[ch].
3694 * Add global clients to expire if they are not on any channel.
3695 This is because normal server will never know if they signoff
3696 if they are not on any channel. The cache expiry will take
3697 case of these entries. This is done by normal servers only.
3698 The affected files are silcd/command_reply.c,
3699 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
3701 * If server receives invalid ID notification for WHOIS or
3702 IDENTIFY and the ID exists in the lists, it is removed.
3703 Affected file silcd/command_reply.c.
3705 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
3706 in client then client entry that it matches is searched and
3707 the nickname is printed on the screen for user. Affected
3708 file irssi/src/silc/core/client_ops.c.
3710 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3712 * Use cache entry expire time in the LIST command reply to
3713 purge old entries from the cache after the LIST command
3714 reply has been received. This way we don't have non-existent
3715 entries in the cache for too long. Affected file is
3716 silcd/command_reply.c.
3718 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3720 * If we are normal server, and we've not resolved client info
3721 in WHOIS or IDENTIFY from router, and it is global client,
3722 we'll check whether it is on some channel. If it is not
3723 then we cannot be sure about its validity and will resolve it
3724 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
3725 file silcd/command.c.
3727 * Search channel by name (if possible) rather than by ID
3728 in IDENTIFY command's command reply. Affected file is
3729 silcd/command_reply.c.
3731 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3733 * Distribute to the channel passphrase in CMODE_CHANGE notify.
3734 Updated specs and implemented it. Affected file silcd/command.c,
3735 silcd/packet_send.c and silcd/packet_receive.c.
3737 * Implemented the <founder auth> payload handling in the JOIN
3738 command. If provided all conditions for channel joining
3739 except requirement to provide correct passphrase can be
3740 overrided by the channel founder. Updated the protocol specs.
3741 Affected file silcd/command.c.
3743 Added support for founder auth in JOIN command in client
3744 library. Fixed the parsing of the JOIN command now to support
3745 all options as they should be. The affected file is
3746 lib/silcclient/command.c.
3748 * Optimized the WHOIS and IDENTIFY commands to send the request
3749 to router only if it includes nicknames or other names. If
3750 they include only IDs then check the local cache first before
3751 routing. Affected file is silcd/command.c.
3753 * Added channels topic announcements. Affected file is
3754 silcd/packet_receive.c and silcd/server.c.
3756 * Fixed the silc_server_send_notify_topic_set to really destine
3757 the packet to channel. Affected file silcd/packet_send.c.
3759 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
3760 library. Affected file lib/silcclient/client_notify.c.
3762 * Added UMODE announcements. Affected file silcd/server.c.
3764 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3766 * Memory leak fixes in:
3768 lib/silcutil/silcsockconn.c
3769 lib/silcske/silcske.c
3770 lib/silcske/groups.c
3772 lib/silccrypt/silcpkcs.c
3773 lib/silccore/silccommand.c
3774 lib/silccore/silcidcache.c
3779 * ROBOdoc documented the lib/silcske/groups.h file and a
3780 bit changed the interface for better.
3782 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
3784 * Update the client entry context in the ID cache after
3785 nick change. Affected file lib/silcclient/command.c.
3786 Fixes the CUMODE command when regaining founder privileges,
3787 and a little WHOIS problem.
3789 * Fixed silc_net_gethostbyname to correctly call the
3790 inet_ntop. Affected file lib/silcutil/silcnet.c.
3792 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
3794 * Added IPv6 support checking to the configure.in.pre, added
3795 also --enable-ipv6 option to override the check. Affected
3796 file configure.in.pre.
3798 * The silc_thread_create now calls the start function
3799 directly if threads support is not compiled in. Removes
3800 ugly #ifdef's from generic code. Affected files are
3801 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
3803 * Added silc_net_gethostby[name/addr]_async to asynchronously
3804 resolve. Affected files are lib/silcutil/silcnet.[ch].
3806 * Added support for rendering IPv6 based server, client and
3807 channel IDs. Affected file lib/silcutil/silcutil.c.
3809 * Added support for creating IPv6 based server IDs. Affected
3810 file is silcd/serverid.c.
3812 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
3814 * Added silc_net_gethostby[addr/name] into the
3815 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
3816 routines. Added silc_net_is_ip[4/6]. Affected file is
3817 lib/silcutil/unix/silcunixnet.c. All routines that take
3818 address as argument now supports both IPv4 and IPv6 addresses.
3820 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
3822 * Fixed LIST command reply sending in server. Affected file
3825 * Server now sends the kicker's client ID in the KICK notify
3826 to the kicked client. Affected file silcd/command.c.
3828 * The client library now parses the kickers client ID and
3829 UI displays it. Affected files lib/silcclient/client_notify.c
3830 and irssi/src/silc/core/silc-channels.c, module-formats.c.
3832 * Made all payload parsing function prototypes consistent.
3833 They all take now const unsigned char * and uint32 pair as
3834 the payload data instead of SilcBuffer. Changes all around
3835 the source tree. Other unsigned char* -> const unsigned char*
3836 changes around the tree as well.
3838 * Optimized SFTP client and server packet sending not to
3839 allocate new buffer for each packet but to recycle the
3840 first allocated buffer. Affected files are
3841 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
3843 * Optimized the SFTP client to use SilcList instead of
3844 SilcDList for requests, because it is faster. Affected file
3845 is lib/silcsftp/sftp_client.c.
3847 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
3848 into lib/silccore/silcid.[ch].
3850 Renamed silcpayload.[ch] into silcargument.[ch].
3852 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
3854 * If client entry is deleted with active key agreement
3855 session, abort the session.
3857 The silc_client_abort_key_agreement now calls the completion
3858 callback with new SILC_KEY_AGREEMENT_ABORTED status.
3860 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
3863 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3865 * Don't use __restrict in older GCC's. Affected file is
3866 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
3868 * silc_net_localhost now attempts to reverse lookup the
3869 IP/hostname. Affected file lib/silcutil/silcnet.c.
3871 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
3872 command. It can be used to gain founder privileges at
3873 the same time when joining the channel.
3875 Defined that the SILC_NOTIFY_TYPE_KICKED send the
3876 kicker's client ID as well. Updated protocol specs.
3878 Defined that the server must send SILC_COMMAND_IDENTIFY
3879 command reply with error status to client who sent
3880 private message with invalid client ID.
3882 Updated the protocol specification.
3884 * Added silc_server_send_command_reply to send any
3885 command reply. Affected file silcd/packet_send.[ch].
3887 * Added silc_id_payload_encode_data to encode ID payload
3888 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
3890 * The server now send IDENTIFY command reply with error
3891 status if client ID in private message is invalid. Affected
3892 file silcd/packet_receive.c.
3894 * Save the server key file with server's IP address in
3895 the filename instead of hostname. The affected file is
3896 irssi/src/silc/core/client_ops.c.
3898 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3900 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
3903 * Added libtool support for compiling shared objects in
3904 lib/silcsim. Affected file configure.in.pre and
3905 lib/silcsim/Makefile.am. Original patch by cras.
3907 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3909 * Pid file configuration, and server's config file fixes
3910 patch by toma. Updated CREDITS file.
3912 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3914 * Fixed silc_client_channel_message to not try to decrypt
3915 the message twice if it resolved the destination client
3916 information. This could cause of dropping one channel
3917 message. Affected file lib/silcclient/client_channel.c.
3919 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3921 * Added silc_client_run_one into lib/silcclient/silcapi.h and
3922 lib/silcclient/client.c. This function is used when the SILC
3923 Client is run under some other scheduler, or event loop or
3924 main loop. On GUI applications, for example this may be
3925 desired to used to run the client under the GUI application's
3926 main loop. Typically the GUI application would register an
3927 idle task that calls this function multiple times in a second
3928 to quickly process the SILC specific data.
3930 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
3932 * Fixed silc_server_drop() for dropping the supplementary
3933 groups as well, this could cause a security hole on some
3936 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3938 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
3941 * Write PID file after dropping privileges. Added -F option
3942 to run server on foreground. A patch by debolaz.
3943 Affected files silcd/server.c, silcd/silcd.c.
3945 * Fixed MOTD to return the MOTD file server name. Affected
3946 file silcd/command.c.
3948 * Added INFO command reply handling to the Irssi SILC Client.
3949 Affected file irssi/src/silc/core/client_ops.c.
3951 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3953 * Fixed the silc_idcache_list_* routines to really support
3954 the dynamic list. Fixes a crash. Affected file is
3955 lib/silccore/silcidcache.c.
3957 * Fixed the LIST command reply to really call LIST command's
3958 pending callbacks. Affected file silcd/command_reply.c.
3960 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3962 * Update conn->local_entry->nickname after giving NICK
3963 command. Affected file lib/silcclient/command.c.
3965 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
3967 * Added the [pid] option to the silcd configuration file
3969 Affected files: serverconfig.[ch] and silcd.c
3971 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3973 * Save fingerprint in WHOIS command reply in server.
3974 Affected file silcd/command_reply.c.
3976 * Fixed NICK commands pending callback registration.
3977 Affected file lib/silcclient/command.c.
3979 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3981 * Use ++server->cmd_ident when sending commands in server,
3982 instead of random number. Affected file silcd/command.c.
3984 * Fixed GETKEY command reply to call actually GETKEY pending
3985 command callbacks. Affected file silcd/command_reply.c.
3987 * A bit stricter check for nicknames. Check for same nickname
3988 in NICK command also. Affected file silcd/command.c.
3990 * Do not call INFO command everytime client ID changes, only
3991 during first connecting. Affected file lib/silcclient/client.c.
3993 * Set the new nickname only after successful command reply for
3994 NICK command is returned by server. Affected file
3995 lib/silcclient/command.c.
3997 * Remove nicknames from nicklist during server_signoff notify.
3998 Should fix /NAMES bit more. The affected file is
3999 irssi/src/silc/core/silc-channels.c.
4001 * Added `fingerprint' field to the SilcIDListData in the
4002 silcd/idlist.h to hold the fingerprint of the client's
4005 Send the fingerprint of the client's public key in WHOIS
4008 Affected files silcd/command.c, and silcd/idlist.[ch].
4010 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
4011 create fingerprint from given data.
4013 * Show the fingerprint of the client's public key in WHOIS.
4014 Affected files irssi/src/module-formats.[ch] and
4015 irssi/src/silc/core/client_ops.c.
4017 * Format the multiple same nicknames also during JOIN and
4018 NICK_CHANGE notifys. Affected file is
4019 lib/silcclient/client_notify.c.
4021 * Do not print error on screen for invalid private message
4022 payload since it can come if someone is sending private
4023 messages with wrong key. Affected file
4024 lib/silccore/silcprivate.c.
4026 * Fixed multiple concurrent /PING crash. Affected file
4027 lib/silcclient/command.c.
4029 * Changed the wrong ID encoding. All IP addresses must be
4030 in MSB first order in encoded format. They were encoded
4031 wrong and was in LSB format. Affected files are
4032 silcd/serverid.c, lib/silcutil/silcutil.c.
4034 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
4036 * Call the `connect' client operation through the scheduler
4037 in case of error. Affected file lib/silcclient/client.c.
4039 * Call the `failure' client operation even if the error
4040 occurred locally during a protocol. Affected file is
4041 lib/silcclient/protocol.c.
4043 * Added support of sending LIST command to router from normal
4044 server. This way normal server can get list of all channels
4045 in the network too. Fixed the channel list sending in the
4046 server too. Affected files are silcd/command.c, and
4047 silcd/command_reply.[ch].
4049 * Added silc_server_update_channels_by_server and
4050 silc_server_remove_channels_by_server. They are used during
4051 disconnection of primary router and in backup router protocol.
4052 Affected file silcd/server_util.[ch], silcd/server.c and
4053 silcd/server_backup.c.
4055 * Fixed channel adding to global list in IDENTIFY command
4056 reply in server. Affected file silcd/command_reply.c.
4058 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
4060 * If the incoming packet type is REKEY or REKEY_DONE process
4061 that packet always synchronously. Fixes yet another MAC
4062 failed error on slow (dialup) connections. Affected file
4063 lib/silcclient/client.c and silcd/server.c.
4065 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
4067 * Call check_version SKE callback for initiator too. Affected
4068 file lib/silcske/silcske.c.
4070 * Implemented fix for security hole found in the SKE that was
4071 fixed in the specification few days back; the initiator's
4072 public key is now added to the HASH value computation.
4073 Added backwards support for the old way of doing it too, for
4074 old clients and old servers. Affected file is
4075 lib/silcske/silcske.c.
4077 * Enabled mutual authentication by default in SKE. If initiator
4078 is not providing mutual authentication the responder will
4079 force it. This will provide the proof of posession of the
4080 private key for responder. The affected files are
4081 lib/silcclient/protocol.c and silcd/protocol.c.
4083 * Do not cache anymore the server's public key during SKE.
4084 We do mutual authentication so the proof of posession of
4085 private key is done, and if the server is authenticated in
4086 conn auth protocol with public key we must have the public
4087 key already. Affected file silcd/protocol.c.
4089 * Added new global debug variable: silc_debug_hexdump. If
4090 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
4091 file lib/silcutil/silclog.[ch].
4093 * Fixed compilation warning due to char * -> const char *.
4094 Affected files lib/silcutil/silcnet.h, and
4095 lib/silccore/silcauth.[ch].
4097 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
4099 * Fixed CMODE command when new channel key was created. If
4100 the creation failed the old key was removed. Next time giving
4101 same command would crash the server since the old key was
4102 freed already. Affected file silcd/command.c.
4104 * Fixed the silc_server_announce_get_channels to not crash
4105 on reconnect. Affected file silcd/server.c.
4107 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
4109 * Added silc_log_set_debug_string function to set a regex
4110 string to match for debug output. Only the function names,
4111 or filenames matching the given debug string is actually
4112 printed. This way it is possible to filter out those debug
4113 strings that user is not interested in.
4115 Fixed a bug in silc_string_regexify.
4117 Affected files lib/silcutil/silclog.[ch], and
4118 lib/silcutil/unix/silcunixutil.c.
4120 * Changed the -d options in both server and Irssi SILC client
4121 to take the debug string as argument. Affected files
4122 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
4124 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
4126 * Added silc_hash_babbleprint to create a Bubble Babble
4127 Encoded fingerprint. The encoding is developed by Antti
4128 Huima (draft-huima-babble-01.txt), and it creates human
4129 readable strings out of binary data. Affected file
4130 lib/silccrypt/silchash.[ch].
4132 * Print the babble print now in addition of fingerprint as well
4133 in Irssi SILC client. Affected files are
4134 irssi/src/fe-common/silc/module-formats.[ch],
4135 irssi/src/fe-common/silc/core/client_ops.c.
4137 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
4139 * Fixed a security problem found in SKE. The initiator's
4140 public key too is now added to the HASH hash value creation
4141 which is signed by the responder to create the SIGN value.
4142 This will prevent anyone in the middle to lie to the responder
4143 about the initiator's public key. If this is done now, the
4144 man in the middle will get caught. Updated the protocol
4147 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
4149 * Better installation directory handling. Configure module
4150 paths and other paths automatically to example_silc* files
4151 in doc/. A patch by toma.
4153 * Fixed compiler warning from MPI library, and from SILC RNG.
4156 * Added SILC_SERVER_PID_FILE to define the pid file for server.
4157 It can be configured with ./configure. A patch by toma.
4159 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
4161 * Find correct make to use in prepare-clean. A patch by
4162 toma. Affected file prepare-clean.
4164 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
4166 * Added irssi variables use_auto_addr, auto_bind_ip,
4167 auto_bind_port and auto_public_ip.
4169 * Changed the interface for silc_client_send_key_agreement
4170 in lib/silcclient/silcapi.h
4174 irssi/src/silc/core/silc-core.c
4176 lib/silcclient/silcapi.h
4177 irssi/src/silc/core/silc-channels.c
4178 lib/silcclient/client_keyagr.c
4181 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
4183 * Added silc_pkcs_public_key_compare to compare two
4184 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
4186 * Check that the client who set the founder mode on the
4187 channel is the same client that is giving the founder
4188 mode to itself. It is done by comparing the saved public
4189 key (it is saved even in the authentication is passphrase).
4190 Affected file silcd/command.c.
4192 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
4194 * Do not process packet for disconnected socket connection.
4195 Affected file lib/silccore/silcpacket.c.
4197 * Process the DISCONNECT packet through scheduler in the
4198 client library. Affected file lib/silcclient/client.c.
4200 * Fixed the silc_client_packet_parse to not to increase
4201 the packet sequence number if the conn->sock and the
4202 current socket connection is not same. This can happen
4203 for example during key agreement when the conn includes
4204 multiple socket connections (listeners). Affected file
4205 lib/silcclient/client.c.
4207 * The sender of the file transfer request now provides also
4208 the pointer (listener) for the key exchange protocol. If
4209 the listener cannot be created then it sends empty key
4210 agreement and lets the receiver provide the listener.
4212 Added `local_ip' and `local_port' arguments to the
4213 silc_client_file_send. If they are provided they are used,
4214 if not then it will attempt to find local IP address, if
4215 not found or bind fails then the remote client will provide
4218 Affected files are lib/silcclient/client_ftp.c and
4219 lib/silcclient/silcapi.h.
4221 * Extended the FILE SEND command to support defining the
4222 local IP and port for key exchange listener. They are

4227 * Defined to WHOIS command reply the sending of fingerprint
4228 of the client's public key (if the proof of posession of the
4229 corresponding private key is verified by the server).
4230 Updated to the protocol specification.
4232 * Added support of receiving the client's public key's
4233 fingerprint in command reply in client library. Affected
4234 file is lib/silcclient/command_reply.c, and
4235 lib/silcclient/idlist.[ch].

4294 preserve the WHOWAS info for the client. Affected file
4295 silcd/server_util.c.
4297 * Fixed SERVER_SIGNOFF notify handling in the server. The
4298 server is now able to process incoming SERVER_SIGNOFF notify
4299 for a server that it doesn't even know about. It will remove
4300 the clients provided in the notify. Affected file
4301 silcd/packet_receive.c.
4303 * Check for partial packet in data queue after every packet that
4304 was found from the queue. Return and wait for more data if
4305 there is partial data in queue. Affected file is
4306 lib/silccore/silcpacket.c.
4308 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>

4323 irssi/src/fe-common/silc/module-formats.[ch].
4325 * Wrote a help file for FILE command.
4327 * Added silc_rng_global_get_byte_fast to get not-so-secure
4328 random data as fast as possible. Random data is read from
4329 /dev/urandom if available and from the SILC RNG if not
4330 available. It is used in padding generation. Affected file
4331 lib/silccrypt/silcrng.[ch].
4333 * All packets in client library are now processed synchronously.
4334 Optimized packet processing a lot. Affected file
4335 lib/silcclient/client.c.

4338 now in server, to optimize packet processing. Affected file
4341 * Include files are installed now only in Toolkit distribution
4342 if make install is given. Affected files: all Makefile.am's.
4344 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4346 * Assure that silc_client_notify_by_server_resolve does not
4347 resolve the client information multiple times. If it cannot
4348 be found by the first it cannot be found at all. Affected
4349 file lib/silcclient/client_notify.c.
4351 * Fixed WHOWAS command reply calling. Affected file
4352 lib/silcclient/command_reply.c.
4354 * Removed all references to silc_idlist_get_client from the
4355 Irssi SILC client since that call is internal call used by
4356 the library. The Irssi SILC client will use now client
4357 retrieval functions found in silcapi.h.
4359 * Fixed a bug in resolving nickname info before sending
4360 private message. It used freed memory. Affected file
4361 irssi/src/silc/core/silc-servers.c.
4363 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4365 * Assure my_channels statistics cannot go negative in server.
4366 Affected files silcd/server.c, silcd/server_util.c.

4382 * Added silc_net_localip to return local host's IP address.
4383 Affected file lib/silcutil/silcnet.[ch].
4385 * If key exchange or rekey protocol is active for a connection
4386 parse all packets syncronously since there might be packets
4387 in packet queue that we are not able to process without first
4388 processing packets before them. Affected file silcd/server,
4389 lib/silcclient/client.c.
4391 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
4392 whether library should continue processing the packet.
4393 Affected file lib/silccore/silcpacket.h.

4439 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
4440 is incomplete and is being resolved, it won't be resolved
4443 Make sure also that USERS command reply does not resolve
4444 twice information. Affected file is
4445 lib/silcclient/command_reply.c.
4447 Make sure that silc_client_get_clients_by_list does not
4448 resolve twice same information.
4450 * Check for valid client->id in the silc_server_free_client_data.
4451 Affected file silcd/server.c.
4453 * Fixed /GETKEY nick@server not to crash if the server entry
4454 is not found. Affected file lib/silcclient/command.c.
4456 * Fixed the silc_server_check_cmode_rights to check the
4457 requested modes correctly. Affected file silcd/command.c.
4459 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
4461 * Better checks for non-printable chars in nick added.
4462 Affected file silcd/command.c.
4464 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4466 * Call the silc_server_udpate_servers_by_server in the
4467 primary router that comes back online in the backup resuming
4468 protocol. Otherwise it routes packets wrong. Affected file
4469 silcd/server_util.[ch], silcd/server_backup.c.
4471 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4473 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
4474 lib/silcutil/silcbuffmt.[ch].
4476 * Redefined the SILC packet header to include the padding
4477 length. Affected file lib/silccore/silcpacket.[ch].
4479 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
4480 length for maximum padding up to 128 bytes). Affected
4481 file lib/silccore/silcpacket.h.
4483 * Removed all backwards support for old 0.5.x MAC thingies.
4484 The SILC packet header change makes it impossible to be
4485 backwards compatible.
4487 * Send the ENDING packet with timeout in the backup resuming
4488 protocol. This is to assure that all routers has connected
4489 to the primary router. Affected file silcd/server_backup.c.
4491 * Changed the RNG to take the first IV from random data. It
4492 used to take it from zero actually. Changed the RNG also
4493 to use /dev/urandom during session. /dev/random is used
4494 in initialization. Affected file lib/silccrypt/silcrng.[ch].
4496 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4498 * Changed the SILC packet header to have the first two bytes
4499 (the packet length) encrypted. Affected files aroung the
4500 code tree, lib/silccore/silcpacket.[ch]. Removed the
4501 SilcPacketCheckDecrypt callback. It is not needed anymore
4502 since the silc_packet_receive_process will determine now
4503 whether the packet is normal or special.
4505 * Implemented the unidirectional MAC keys. Affected files
4506 lib/silcske/silcske.c, silcd/protocol.c and
4507 lib/silcclient/protocol.c.
4509 * Implemented the packet sequence number to the MAC computation.
4510 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
4511 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
4512 lib/silcclient/protocol.c.
4514 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4516 * Allow backup router to announce servers. All servers
4517 announced by backup router are added to the global list
4518 automatically. Update hte server's socket to our primary
4519 router also when backup router announces a server.
4520 Affected file silcd/packet_receive.c.
4522 * Do not update the client->router in the function
4523 silc_server_udpate_clients_by_server if the client is on
4524 global list. We might fail to find any specific server
4525 for locally connected clients and local cell clients. They
4526 should still use the `from' and not `to' as client->router.
4527 This fixes backup router resuming protocol. Affected file
4528 silcd/server_util.c.
4530 * Decrease channel statistics count only if the channel
4531 deletion worked. Affected files are silcd/server.c and
4532 silcd/server_util.c.
4534 * Added silc_server_update_servers_by_server to update origin
4535 of all server entries. Used during backup router protocol.
4536 Affected files silcd/server_util.[ch], silcd/server.c. and
4537 silcd/backup_router.c.
4539 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
4540 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
4541 silc_hmac_get_hash and silc_hmac_get_name. Affected file
4542 lib/silccrypt/silchmac.c.
4544 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4546 * Assure that router cannot reroute the same channel message
4547 to the sender. Affected file silcd/packet_receive.c.
4549 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4551 * Made better checks that the channel message is not sent
4552 to the router it came from. Affected file is
4553 silcd/packet_send.c. Fixed memory leak too.
4555 * Announce informations for incoming router connection, but
4556 only after checking if it is replaced by backup router.
4557 Affected file silcd/packet_receive.c.
4559 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4561 * Fixed the backup resuming protocol to work in multiple
4562 router environment. Affected file silcd/server_backup.c.
4564 * Route packet only to one router in the function
4565 silc_server_packet_send_to_channel. Affected file is
4566 silcd/packet_send.c.
4568 * Fixed silc_server_send_notify_dest to set the broadcast
4569 flag. Fixed the silc_server_send_notify_topic to actually
4570 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
4571 Affected file silcd/packet_send.c.
4573 * Changed the SFTP Filesystem interface. Changed the
4574 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
4575 the filesystem operation function. The SilcSFTPFilesystem
4576 is now a context that is allocated by all filesystem allocation
4577 functions and it already includes the operations structure
4578 and filesystem specific context. It is given as argument
4579 now to the silc_sftp_server_start. This made the interface
4580 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
4581 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
4583 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4585 * Changed the backup router adding and getting interfaces
4586 in the server. The router that will be replaced by the
4587 specified backup router is now sent as argument. Affected
4588 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
4591 * Added silc_net_addr2bin_ne to return the binary form of
4592 the IP address in network byte order. Affected files
4593 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
4595 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4597 * Check for existing server ID in silc_server_new_server
4598 and in silc_server_connect_to_router_final and remove the
4599 old entry if it exists. Affected file silcd/packet_receive.c,
4602 * Send the channel message always to only one router, either
4603 in upstream or downstream. Affected file is
4604 silcd/packet_send.c.
4606 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4608 * Wrote the definition of the backup resuming protocol to the
4609 protocol specification.
4611 * Removed one redundant channel key generation from normal
4612 server during joining procedure. Removed one redundant
4613 channel key sending from server to router during joining
4614 procedure. Affected file silcd/command.c.
4616 * Made minor bugfixes to the backup router resuming protocol.
4617 Affected file silcd/server_backup.c, server.c.
4619 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4621 * Added --disable-asm configuration option. Affected files
4622 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
4625 * Implemented the backup resuming protocol that is used to
4626 resume the primary router position in the cell after the
4627 primary router comes back online. Affected files
4628 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
4629 and silcd/server_util.[ch].
4631 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4633 * Sleep two (2) seconds after sending QUIT command to server.
4634 Affected file lib/silcclient/command.c.
4636 * Assure that if outgoing data buffer is pending do not force
4637 send any data. Affected file silcd/packet_send.c.
4639 * Assure that if outgoing data buffer is pending do not force
4640 send any data. Affected file lib/silcclient/client.c.
4642 * Implemented the backup router support when the primary router
4643 goes down. The servers and routers can now use the backup
4644 router as new primary router without loosing connectivity.
4646 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4648 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
4649 in the server to indicate disabled entry. All data read
4650 from the connection will be ignored and no data is sent
4651 for entry that is disabled. Affected files are
4652 silcd/idlist.h, silcd/server.c.
4654 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4656 * Created SFTP client and server test programs in the
4657 lib/silcsftp/tests directory.
4659 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4661 * Implemented memory filesystem (virtual filesystem) for
4662 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
4665 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4667 * Implemented the SFTP (SSH File Transfer Protocol) to the
4668 lib/silcsftp. It includes SFTP client and SFTP server
4671 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4673 * Moved lib/silccore/silcprotocol.[ch] to the
4674 lib/silcutil library.
4676 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
4677 take variable argument list pointer as argument. Affected
4678 file lib/silcutil/silcbuffmt.[ch].
4680 * Added silc_buffer_set function that is used to set data
4681 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
4682 Affected file lib/silcutil/silcbuffer.h.
4684 * Changed various routines in the core library to use the new
4685 silc_buffer_set instead of allocating new buffer only for
4688 * Added 64-bit value formatting and unformatting support to the
4689 silc_buffer_[un]format routines. Affected file is
4690 lib/silcutil/silcbuffmt.[ch].
4692 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
4693 to includes/bitmove.h.
4695 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4697 * Fixed channel user mode saving in client library. Affected
4698 file lib/silcclient/command[_reply].c.
4700 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4702 * Defined the file transfer to the SILC Protocol. Added
4703 new packet type SILC_PACKET_FTP and defined File Transfer
4704 Payload. The mandatory file transfer protocol is SFTP
4705 (SSH File Transfer Protocol). Affected file in addition
4706 of the internet draft is lib/silccore/silcpacket.h.
4708 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
4709 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
4710 is used as part of backup router protocol when the primary
4711 router of the cell is back online and wishes to resume
4712 the position as primary router.
4714 * Redefined the MAC generation keys in the protocol. The
4715 same key is not used anymore in both direction. Both
4716 direction will now use different keys for sending and
4717 receiving. This fixes a potential security flaw. This
4718 change causes incompatibilities in the protocol.
4720 * Redefined also the MAC computation from the packet.
4721 An packet sequence number is now added to the MAC
4722 computation. This prevents possible replay attacks against
4723 the protocol. This change too causes incompatibilities
4726 Added `sequence' field to the SilcPacketContext to hold
4727 the current sequence number for the packet.
4729 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4731 * Added `created' field to the SilcIDListData in the file
4732 silcd/idlist.h to indicate the time when the entry was
4735 * Added `created' field to the SilcChannelEntry too. Affected
4736 file silcd/idlist.h.
4738 * Added `creation_time' aguments to all the announcement functions
4739 in the server. If it is provided then only the entries that
4740 was created after the provided time frame are actually
4741 announced. Affected file silcd/server.[ch].
4743 * The protocol says that the Channel ID's IP address must be
4744 based on the router's IP address. Added check for this in
4745 the silc_server_new_channel when processing incoming New Channel
4746 Payload. Affected file silcd/packet_receive.c.
4748 * Print out the correct version with --version in SILC client.
4749 Affected file irssi/src/silc/core/silc-core.c.
4751 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4753 * Fixed WHOWAS command to check for completnes of the client
4754 entry always, not just when the command is coming from client.
4755 Affected file silcd/command.c.
4757 * Added new function silc_server_packet_queue_purge to purge the
4758 outgoing data queue to the network. After the function returns
4759 it is guaranteed that the outgoing packet queue is empty.
4760 Affected file silcd/packet_send.[ch].
4762 * Purge the outgoing packet queue in the rekey protocol's final
4763 callback to assure that all rekey packets go to the network
4764 before quitting the protocol. Affected file silcd/server.c.
4766 * Added silc_client_packet_queue_parse as similar function as
4767 in server to the client library. The affected file is
4768 lib/silcclient/client.c.
4770 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4772 * Splitted silcd/server.c and created silcd/server_util.[ch]
4773 for utility functions.
4775 * Added new socket flag SILC_SF_DISABLED to indicate that the
4776 connection is open but nothing can be sent to or received from
4777 the connection. Affected file lib/silcutil/silsockconn.[ch].
4778 The checking for disabled socket is checked in the low level
4779 silc_socket_write and silc_socket_read functions.
4781 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4783 * Allow only nicknames and channel names that fits into the
4784 7-bit unsigned char ASCII set. Affected file silcd/command.c.
4786 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4788 * When processing JOIN command reply in server check that if
4789 the channel exists in our global list we'll move it the local
4790 list. Affected file silcd/command_reply.c.
4792 * Fixed the check whether client is joined on the channel already
4793 in JOIN command. Affected file lib/silcclient/command.c.
4795 * Fixed the JOIN command reply to check whether the channel
4796 already exists. Affected file lib/silcclient/command_reply.c.
4798 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4800 * Added silc_ske_status_string to map the SKE error numbers
4801 to readable strings. The affected files are
4802 lib/silcske/silcske[_status].[ch].
4804 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4806 * Do not show the private channels on the WHOIS channel list
4807 as it is not allowed by the protocol. The affected file is
4810 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4812 * Assure that the packet length digged from the actual packet
4813 is something sensible in the silc_packet_decrypt_rest_special
4814 in lib/silccrypt/silcpacket.c.
4816 * Free and NULL the allocated pointer in silc_hmac_alloc if
4817 the HMAC allocation fails. The affected file is
4818 lib/silccrypt/silchmac.c.
4820 * Print the selected security properties to the log files in
4821 the server. Affected file silcd/protocol.c.
4823 * Add SKE's reference counter even if calling the completion
4824 callback manually. Otherwise it goes negative, although it
4825 does not cause any problems. The affected file is
4826 lib/silcske/silcske.c.
4828 * Remove the client entry with short timeout after giving the
4829 KILL command. Affected file lib/silcclient/command.c.
4831 * Fixed to send error reply in WHOIS and IDENTIFY commands in
4832 case all found clients are already disconnected (WHOWAS would
4833 found them) in the server. Affected file silcd/command.c.
4835 * Update the last_receive (time of last data received) to be
4836 updated only when received private or channel message so that
4837 the idle time showed in WHOIS makes more sense.
4839 * Added boolean field `valid' in to the SilcClientEntry in the
4840 client library to indicate whether the entry is valid or not.
4841 This fixes the nickname change bug on channel when changing
4842 the nickname to be same than the old (like nick to Nick) the
4843 nickname formatter doesn't set the new nick anymore to Nick@host.
4844 Affected file lib/silcclient/idlist.[ch].
4846 * Now actually fixed the nickname changing on disconnection.
4847 Added new function silc_change_nick to the Irssi SILC Client.
4848 Affected file irssi/src/silc/core/client_ops.c,
4849 irssi/src/silc/core/silc-nicklist.[ch].
4851 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4853 * Check that the public key exists in the GETKEY command before
4854 trying to encode it. Affected file silcd/command.c.
4856 * Print some notifications on received public keys with GETKEY
4857 command in the Irssi SILC Client. Affected files are
4858 irssi/src/fe-common/silc/module-formats.[ch],
4859 irssi/src/silc/core/client_ops.c.
4861 * Use IDENTIFY command to resolve the server information in the
4862 GETKEY command instead of INFO command. Affected file
4863 lib/silcclient/command.c.
4865 * All command reply functions in the client library now calls
4866 the pending command reply callbacks even if an error has
4867 occurred. The server has done this a long time and now it was
4868 time to move the client library to this as well. Now all
4869 errors can be delivered back to the pending command reply
4870 callbacks if necessary. Affected files are
4871 lib/silcclient/command[_reply].[ch].
4873 * Change the nickname on disconnection back to the username
4874 because in reconnect the server will enforce it to it anyway.
4875 Affected file irssi/src/silc/core/silc-servers.c.
4877 * Fixed a config file parsing bug in the Irssi SILC client.
4878 Affected file irssi/src/silc/core/clientconfig.c.
4880 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4882 * When printing the channel mode on JOIN, verify that the
4883 channel key and channel's HMAC are valid. Affected file
4884 irssi/src/silc/core/client_ops.c.
4886 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4888 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
4889 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
4890 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
4892 * Removed channel key rekey task deleting from the function
4893 silc_server_save_channel_key. Affected file silcd/server.c.
4894 Added explicit timeout task context instead that is used to
4895 delete the task if we are registering a new task before the
4896 new task has elapsed.
4898 * When channel key rekey occurs the client library now saves
4899 the old channel key for a short period of time (10 seconds) and
4900 is able to use it in case some is still sending channel
4901 messages encrypted with the old key after the rekey. Affected
4902 file lib/silcclient/[idlist.h|client_channel.c].
4904 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4906 * Added check to the silc_server_new_id_real to not accept
4907 new ID if it is the sender's own ID. Affected file is
4908 silcd/packet_receive.c.
4910 * Assure that we do not announce ourself or the one we've
4911 sending our announcements when we're router and are announcing
4912 servers to our primary router. Affected file silcd/server.c.
4914 * Fixed silc_server_command_identify_check_client to assemble
4915 correct WHOIS packet. It send corrupted WHOIS packet and
4916 caused problem with router to router connections. Affected
4917 file silcd/command.c.
4919 Fixed also silc_server_command_whois_check the same way
4920 as for the IDENTIFY command.
4922 * Added new SilcIDListStatus to the server in the SilcIDListData
4923 structure. The status now includes the current status of
4924 the entry (like registered, resolved etc.). Affected file
4925 silcd/idlist.[ch]. Defined a bunch of different status types
4926 as well. This replaced the old boolean registered field as well.
4928 Added resolve_cmd_ident field to the SilcClientEntry structure
4929 too so that if the entry is for example being resolved so
4930 another command may attach to the same pending command reply
4931 without requiring to resolve the same entry again. This concept
4932 should optimize the WHOIS and the IDENTIFY resolving under
4933 heavy load by taking away unnecessary resolving for entries
4934 that are being resolved already.
4936 Added support for adding multiple pending commands for one
4937 command idenfier. Affected file silcd/command[_reply].[ch].
4939 * Fixed WHOIS and IDENTIFY save to remove the cache entry
4940 before deleting the data. Otherwise the hash table will have
4941 freed data in comparison functions. Affected file is
4942 silcd/command_reply.c.
4944 * Fixed silc_idlist_replace_client_id to add the new entry to
4945 the cache with NULL nickname. Otherwise there will be invalid
4946 memory as the nickname after the nickname is freed. Affected
4947 file silcd/packet_receive.c.
4949 * Fixed the silc_idlist_get_clients_by_hash. The entries was
4950 saved into wrong slots because the previous number of entries
4951 was not taken into account. Affected file silcd/idlist.c.
4952 Fixed same thing in silc_idlist_get_clients_by_nickname too.
4954 * If we are router and we receive JOIN notify to a channel that
4955 does not have any users then notified client is marked as the
4956 channel founder, as it is it. The affected file is
4957 silcd/packet_receive.c
4959 * Added to the extended hash table API's table_del_*ext functions
4960 the destructor as argument too, so that the caller can decide
4961 which destructor to use or whether to use destructor at all.
4962 Affected file lib/silcutil/silchashtable.[ch].
4964 * Fixed ID Cache purging. It actually deleted the entries from
4965 the hash table after the data was freed. The hash table ended
4966 up comparing freed memory. The affected file is
4967 lib/silccore/silcidcache.c.
4969 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4971 * Fixed Irssi SILC client's KILL command's HELP syntax.
4973 * The USERS command now resolves the detailed user information
4974 if the userinfo field is missing. Affected file is
4975 lib/silcclient/command_reply.c.
4977 * Do not print error in silc_file_read if the read file does
4978 not exist. Just silently return NULL. Affected file is
4979 lib/silcutil/silcutil.c.
4981 * Fixed the silc_log_output to not wine about NULL filename
4982 and to not create some bogus " " filename. Affected file is
4983 lib/silcutil/silclog.c.
4985 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4987 * Fixed various printing bugs on the user interface in the
4988 Irssi SILC Client. Minor changes that were forgotten from
4991 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4993 * Fixed the configure.in.pre and the compilation and distribution
4994 environment to support the new autoconf 2.52. That version is
4995 now required to compile the CVS trunk.
4997 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4999 * Renamed function silc_parse_nickname to silc_parse_userfqdn
5000 to generally parse user@fqdn format strings. Affected file
5001 lib/silcutil/silcutil.c.
5003 * Added nickname_format and nickname_force_format fields to the
5004 SilcClientParams structure. The first one defines the format
5005 for the nicknames that the library will enforce if the receives
5006 multiple same nicknames. The second one is boolean value and
5007 can be used to force the library to always enforce the format
5008 to the nicknames regardles whether there are multiple nicknames
5009 or not. This configurable formatting was employed to flexibly
5010 support accessing multiple nicknames from the user interface.
5011 The userinterface can now set the nicknames to what ever format
5012 they prefer. Affected file lib/silcclient/silcapi.h.
5014 Added function silc_client_nickname_format to the file
5015 lib/silcclient/idlist.c. It performs the nickname formatting.
5017 Added new field `hostname´ to the SilcClientEntry context.
5018 It holds the hostname of the client. Affected file is
5019 lib/silcclient/idlist.h.
5021 * Irssi SILC Client sets the nicknames in nick@hostn format.
5022 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
5023 irssi/src/silc/core/silc-core.c.
5025 The WHOIS printing now also shows both the real nickname and
5026 the formatted nickname so that user knows how to access the
5027 user if there are multiple same nicknames cached. Affected
5028 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
5029 printing formatting too to take the hostname now as a separate
5030 argument. The Affected file is
5031 irssi/src/fe-common/silc/modules-formats.[ch].
5033 * Changed the silc_client_get_clients_local to accept the formatted
5034 nickname as argument. It accepts the real nickname too but the
5035 formatted nickname can be used to find the true entry from
5036 multiple entries. Affected file lib/silcclient/silcapi.h and
5037 lib/silcclient/idlist.c.
5039 * Added nickname_format_parse field to the SilcClientParams.
5040 It is a callback function provided by the application to parse
5041 the nickname out of the formatted nickname string. The library
5042 calls it to get the nickname from the formatted string. Since
5043 the application generally knows better the format of the nickname
5044 string it parses it instead of the library, even though library
5045 encodes the formatted string. If the callback function is not
5046 provided then the library will use the string as is. The
5047 affected file is lib/silcclient/silcapi.h.
5049 * All the nickname strings passed to the client library in
5050 commands are now expected to be formatted nickname strings.
5051 If the command does not support the formatted nickname string
5052 it will assume that the sent string is the actual nickname.
5053 Affected file lib/silcclient/command.c.
5055 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5057 * Added public key authentication support to OPER and SILCOPER
5058 commands in the client library. Affected file is
5059 lib/silcclient/command.c.
5061 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5063 * Changed the get_auth_methdod client operation to be asynchronous.
5064 It can be async if the application resolves the authentication
5065 method from the server during the negotiation. Added new
5066 SilcGetAuthMeth completion callback that the application will
5067 call after resolving the authentication method.
5069 Added function silc_client_request_authentication_method that
5070 the application can use to resolve the authentication method
5071 from the server. Added also SilcConnectionAuthRequest callback
5072 that the library will call after the server has replied. The
5073 application can call this function if it does not know the
5074 current authentication method.
5076 Affected files are lib/silcclient/client.c and
5077 lib/silcclient/silcapi.h.
5079 * The Irssi SILC client now automatically resolves the authentication
5080 method incase any configuration information is not present (and
5081 currently there never is). The affected file is
5082 irssi/src/silc/core/client_ops.c.
5084 * Fixed public key authentication from the client library.
5085 Affected file lib/silcclient/protocol.c. Changed also the
5086 protocol specification about the public key authentication in
5087 the connection authentication protocol. The actual data to be
5088 signed is now computed with a hash function before signing.
5090 * Fixed the public key authentication from the server as well.
5091 Affected file silcd/protocol.c.
5093 * Removed the mlock()'s from the memory allocation routines.
5094 Affected file lib/silcutil/silcmemory.c. The ./configure does
5095 not check anymore for the mlock(). Affected file is
5098 * Fixed USERS command in server to allow the execution of the
5099 command for private and secret channels if the client sending
5100 the command is on the channel. Affected file silcd/command.c.
5102 * Fixed silc_client_get_clients_local to return the clients
5103 count correctly. It could return wrong value. Affected file
5104 lib/silcclient/idlist.c.
5106 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5108 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
5109 types. The assembler optimizations seemed not to like 64-bit
5110 data types. The assmebler optimizations thus are now enabled
5111 also for BSD systems as opposed to only enable them for Linux.
5113 * Do not check for threads at all on BSD systems. Affected
5114 file configure.in.pre.
5116 * Removed -n and -h options from the Irssi SILC Client since
5117 they are not used in silc.
5119 * Fixed the prime generation to assure that the first digit
5120 of the generated random number is not zero since our conversion
5121 routines does not like number strings that starts with zero
5122 digit. If zero digit is seen the random number is regenerated.
5123 This caused some corrupted RSA keys when the zero first digit
5124 was met. Affected file lib/silcmath/silcprimegen.c.
5126 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5128 * Fixed WIN32 configuration in the ./configure script.
5129 Fixed to include xti.h on environments that has it.
5130 Patches by Carsten Ilchmann and andrew.
5132 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5134 * Changed the silc_id_create_client_id to be collision
5135 resistant. It is now assured that there cannot be created
5136 two same client ID's. I suspect that some weird bugs in
5137 the server were actually caused by duplicate Client IDs.
5138 Affected file silcd/serverid.[ch]. A router receiving
5139 new ID now also assures and informs the sending server
5140 if the ID caused collision.
5142 * Changed the silc_id_create_channel_id to also assure that
5143 there are no collisions.
5145 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5147 * Statement about ignoring the Mutual Authentication flag when
5148 performing rekey with PFS was a bit misleading. It is ignored
5149 if it was set in the initial negotiation, it cannot be even
5150 set in the rekey. Fixed in the ke-auth draft. Started the
5151 new versions of the protocol drafts in the doc/.
5153 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5155 * Fixed a bug in silc_client_command_identify_save when saving
5156 new channel information. The channel name was no duplicated
5157 and caused crash on exit. Affected file is
5158 lib/silcclient/command_reply.c.
5160 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5162 * Fixed the getkey command handling in the server. Send just
5163 empty OK reply to the sender if the key could not be fetched
5164 (but everything else was ok, like the key just was not available).
5165 Changed the public key parameter to optional in the protocol
5166 specs so that empty OK reply can be sent. Affected file
5169 Added a message to Irssi SILC client to tell to user if the
5170 server did not return a public key.
5172 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
5174 * Fixed a channel key regeneration bug. It registered new
5175 timeout tasks exponentially until all system resources were
5176 used. Affected file silcd/server.c.
5178 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5180 * Added the SILC Document generator to the scripts/silcdoc.
5181 It can be used to generate the Toolkit Reference Manual out
5182 of the source tree. Internally it will also use the RoboDoc
5183 generator now imported in util/robodoc.
5185 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5187 * Added couple of return's in rekey protocol if error orccurred
5188 during the protocol. The execution must be terminated.
5189 Affected file silcd/protocol.c. Also, terminate the protocol
5190 always with timeout.
5192 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5194 * The client's Client ID was created initally from the wrong
5195 nickname (it could have been in format nick@host) in the
5196 silc_server_new_client. Affected file silcd/packet_receive.c
5198 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5200 * Added some SILC_LOG_ERROR's to various error conditions
5201 if client could not be added to ID cache. Affected files
5202 silcd/packet_receive.c and silcd/server.c.
5204 * When client's sock->user_data is freed, NULL also the
5205 client->router and client->connection pointers. Added check
5206 for these pointers being NULL to various places around the
5207 code. Affected file silcd/server.c.
5209 * Added client->data.registered == TRUE checks to various
5210 places around the code to assure that unregistered client's
5211 are not handled when it is not allowed. Affected file
5214 * Added `bool registered' fields to all
5215 silc_idlist_[server|client]_get_* routines to indicate whether
5216 the fetched client needs to be registered or not. Affected
5217 file silcd/idlist.[ch].
5219 * Add your own entry as registered to the ID cache in the
5220 server. Affected file server.c.
5222 * Fixed a bug in silc_server_new_server. The SilcServer was
5223 set as the new server's context instead of SilcServerEntry.
5224 This naturally caused some weird bugs.
5226 * Added "updated" field the SilcChannelEntry which indicates
5227 the time since the channel entry was last accessed. This
5228 can be used to determine whether it is necessary to
5229 announce the channel after backup resuming protocol.
5230 Affected files silcd/idlist.[ch].
5232 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5234 * Do not delete the channel rekey task when adding it
5235 for in silc_server_create_channel_key.
5237 * Changed the silc_server_create_channel_key to return
5238 TRUE or FALSE to indicate the success of the channel key
5241 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5243 * Fixed MSVC++ project files and added missing files to

5246 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5248 * Do not add TCP_NODELAY flag if the operating system
5249 does not have it defined. Affected files are
5250 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
5252 * Fixed buffer overflow from Irssi SILC Client. Affected
5253 file irssi/src/fe-common/core/themes.c.
5255 * Fixed double free in client library in the file
5256 lib/silcclient/client.c when disconnecting from server.
5258 * Applied double free patch from cras to Irssi SILC client.
5259 Affected files irssi/src/core/[modules/expandos].c
5261 * Fixed the disconnection handling to Irssi SILC Client.
5262 The application must call silc_client_close_connection
5263 in ops->connect client operation in case of failure of
5264 the connection. Affected file is
5265 irssi/src/silc/core/client_ops.c.
5267 * Do not set sock->protocol to NULL in the function
5268 silc_client_close_connection after executing the protocol's
5269 final callback since the sock might not be valid anymore.
5270 Affected file lib/silcclient/client.c.
5272 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5274 * Do not enable SILC_THREADS if the linking with libpthread
5275 did not happen. Affected file configure.in.pre.
5277 * Added notion to protocol specification that server must
5278 verify the sent authentication payload with CMODE when
5279 setting the channel founder key. Implemented it to the
5280 server. Affected file silcd/command.c.
5282 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5284 * Added _EXTRA_DIST SILC distribution variable to the
5285 distributions file. It is used to conditionally add extra
5286 files or directories to the specific distribution. Affected
5287 files ./prepare, Makefile.am.pre and distributions.

5292 * Added README.WIN32 for instructions to compile the Toolkit
5295 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5297 * Fixed a double free in disconnection in the server. Affected
5298 file is silcd/server.c.
5300 * Fixed the lib/silcske/groups.c to work now also with GMP
5301 MP library. The string conversion did not work when using
5302 specific base and the base is indicated in the string as well.
5304 * Created win32/ directory which now includes MSVC++ specific
5305 stuff so that toolkit (DLLs) may be compiled with MSVC++.
5306 It will appear only in the toolkit distribution
5308 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5310 * Changed the key material distribution function in case when
5311 the hash output is too short. The data is now concatenated
5312 a bit differently than it used to. Made the change to the
5313 SKE protocol specification.
5315 * Added better GMP detection to configure.in.pre. A patch
5318 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5320 * Fixed a minor bug in SKE that might cause some problem on
5321 some platforms. Affected file lib/silcske/silcske.c.
5323 * Added the cookie checking for initiator in the SKE. It checks
5324 that the responder returns the sent cookie unmodified. The
5325 affected file is lib/silcske/silcske.c. Added new SKE
5326 error type INVALID_COOKIE that can be sent during the
5327 negotiation. Fixed some memory leaks as well.
5329 * Added the "invalid cookie" error message to Irssi SILC client's
5332 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5334 * Added `task_max' field to the SilcClientParams to indicate
5335 the maximum tasks the scheduler can handle. If set to zero,
5336 default values are used. Affected file lib/silcclient/silcapi.h.
5338 * Fixed memory leaks in silc_client_close_connection. Affected
5339 file lib/silcclient/client.c.
5341 * Added silc_client_del_client_entry to client library to free
5342 all memory of given client entry. Affected file is
5343 lib/silcclient/idlist.[ch].
5345 * Added new functions silc_client_del_channel and
5346 silc_client_del_server to delete channel and server entries.
5347 Affected file lib/silcclient/[silcapi.h/idlist.c].
5349 * Removed silc_client_del_client_by_id from silcapi.h.
5351 * Fixed the INFO command to return the server's own info
5352 correctly when querying by Server ID. Affected file is
5355 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5357 * Removed the non-blocking settings in WIN32 code in the
5358 silc_sock_[read/write] and added SleepEx instead. Affected
5359 file lib/silcutil/win32/silcwin32sockconn.c. The availability
5360 of input data is now checked with FIONREAD and ioctlsocket.
5362 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5364 * Call silc_schedule_task_del_by_context in the
5365 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
5366 Affected file lib/silccore/silcprotocol.c.
5368 * Call silc_protocol_cancel for active protocols in the
5369 silc_server_close_connection if the funtion
5370 silc_server_free_sock_user_data has not been called.
5371 Affected file silcd/server.c.
5373 * Generic tasks cannot be deleted using the del_by_fd
5374 task deleting function since generic tasks does not match
5375 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
5377 * Added a notion to SILCOPER help file that the SILCOPER works
5378 only on router server, not on normal server.
5380 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5382 * Added for WIN32 support for the new scheduler as well.
5383 Affected file lib/silcutil/win32/silcwin32schedule.c.
5385 * Fixed the SHA1 implementation to work on various platforms.
5387 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5389 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
5390 API. It is part of the scheduler now. Everything else is
5391 as previously but some functions has changed their names.
5392 Checkout the lib/silcutil/silcschedule.h for the interface.
5393 Updated all applications to use the new interface. Affected
5394 files are lib/silcutil/silcschedule.[ch].
5396 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5398 * Found a bug in the SKE implementation. The HASH value,
5399 specified by the protocol, was not computed correctly. The
5400 public key of the responder was not added to the computation
5401 even though it is mandatory. Affected file lib/silcske/silcske.c.
5402 This unfortunately causes incompatibilities with older
5403 clients and servers.
5405 * Added WIN32 specific network init and uninit functions:
5406 silc_net_win32_init and silc_net_win32_uninit to init and uninit
5407 the Winsock2. Affected file lib/silcutil/silcnet.h and
5408 lib/silcutil/win32/silcwin32net.c.
5410 * Set the socket always to nonblocking mode on WIN32 after
5411 reading data or writing data. Affected file is
5412 lib/silcutil/win32/silcwin32sockconn.c.
5414 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5416 * Fixed various compilation problems under WIN32. Affected
5417 files lib/silcutil/win32/silcwin32thread.c and
5418 lib/silcutil/win32/silcwin32schedule.c.
5420 * Removed all _internal.h #includes from public header
5421 files. Internal headers must never be included from
5424 Removed also the lib/silcske/payload_internal.h file.
5426 * All include files that may be needed (public and some others
5427 included by the public headers) by application developers are
5428 now copied to the ./includes directory. It does not copy any
5429 internal headers. Affected file Makefile.defines.pre and all
5430 Makefile.am's under lib/ and subdirs.
5432 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5434 * Do not change the ~/.silc directory's permissions automatically.
5435 Affected file irssi/src/silc/core/clientutil.c.
5437 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5439 * Do not cancel the protocol in silc_server_close_connection
5440 it might cause recursion. Now cancelled in the function
5441 silc_server_free_sock_user_data. Affected file silcd/server.c.
5443 * Fixed the silc_server_remove_clients_by_server to regenerate
5444 the channel keys correctly finally. Added also new function
5445 silc_server_remove_clients_channels to actually do it.
5446 Affected file silcd/server.c.
5448 * Fixed the silc_server_new_channel to not crash by giving
5449 wrong router to the new channel. Affected file is
5450 silcd/packet_receive.c.
5452 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5454 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
5455 which is given as argument to the silc_client_alloc now.
5456 It can be used to configure the client and set various parameters
5457 that affect the function of the client.
5459 * The USERS command in server did not check whether the channel
5460 is private or secret. Affected file silcd/command.c.
5462 * Added new argument to the USERS command in protocol specification.
5463 The USERS command now can take the channel name as argument
5464 as well. Added support for this in client and server and
5465 updated the protocol specs.
5467 * Completed the GETKEY command in client. It can be now used
5468 to fetch also servers public key not only some clients.
5469 Affected files lib/silcclient/command[_reply].c.
5471 * Added silc_client_get_server to return server entry by the
5472 server name. Affected files lib/silcclient/silcapi.h and
5475 * Redefined the IDENTIFY command in protocol specification to be
5476 more generic. It now can be used to query information about
5477 any entity in the SILC Network, including clients, servers and
5478 channels. The query may be based either the entity's name
5479 or the ID. Added support for this in both client and server.
5481 Affected files silcd/command.c and lib/silcclient/command.c
5482 and command_reply.c.
5484 * Optimized the WHOIS and WHOWAS commands in the server. Removed
5485 the _from_client and _from_server functions. Affected file
5488 * Added silc_client_get_channel_by_id_resolve to the file
5489 lib/silcclient/silcapi.h to resolve channel information by
5490 its ID. Added also silc_client_get_channel_by_id that
5491 does not resolve it from the server.
5493 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5495 * Added SilcServerEntry context into the client library
5496 to represent one server. The INFO command now allocates
5497 these to save the resolved server info. For now on the
5498 client library will also keep information about servers,
5499 connected and resolved with INFO.
5501 The INFO command now allocates the SilcServerEntry context
5502 and saves the server info there. The COMMAND_REPLY in
5503 the INFO now returns the parameters to application in
5504 same order as defined in the protocol specification.
5506 The entries are cached in the client->server_cache.
5508 * The INFO command is now issued after received the Client ID
5509 from the server. Affected file lib/silcclient/client.c.
5511 * The CMODE_CHANGE notify may now return also an SilcServerEntry
5512 to the application as the mode changer might be server.
5513 It is guaranteed that NULL is not returned anymore to the
5514 application. Affected file lib/silcclient/client_notify.c.
5516 The ID Type is now also passed to the application so that
5517 it can check whether the returned entry is SilcClientEntry
5520 Added new function silc_client_get_server_by_id to return
5521 the server entry by ID. Affected files are the
5522 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
5524 * Do not create the channel in the Irssi SILC Client when issuing
5525 the JOIN command but when received the sucessful JOIN command
5526 reply. Otherwise the channel might get created even though we
5527 could not join it. The Affected file is
5528 irssi/src/silc/core/[silc-channels.c/client_ops.c].
5530 * Fixed a channel joining bug in router. The router must also
5531 check the channel modes, invite and ban lists etc. when serving
5532 the JOIN command sent by normal server. Affected file is
5533 silcd/command.c. The router now resolves the client's
5534 information from the server who sent the JOIN command if it
5535 does not know it, and processes the JOIN command only after
5538 * Changed the SilcCommandCb to take new argument; void *context2.
5539 Affected file lib/silccore/silccommand.h
5541 The second argument in the command callbacks in the server now
5542 includes the SilcServerCommandReplyContext if the command was
5543 called as pending command callback from the command reply.
5544 Otherwise it is NULL. When called as pending the status of the
5545 command reply will be checked and if it was erronous the
5546 error will be sent to the original sender of the command.
5547 This way the client always receives the error messages even
5548 though the server was actually the one who received the error
5549 when it resent the command to router, for example. Affected
5550 files silcd/command[_reply].[ch].
5552 * Fixed sending WHOWAS command's error message to client if
5553 the requested client could not be found. It was missing.
5556 * Changed the CMODE and CUMODE commands reply arguments in the
5557 protocol specification. The Channel ID is now sent in both
5558 of the commands to identify the channel. Implemented this
5559 new feature to the client and server. Affected files
5560 lib/silcclient/command_reply.c and silcd/command.c.
5562 * Made better checks for invite and ban lists in the JOIN
5563 command in server. Affected file silcd/command.c.
5565 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5567 * The server now performs the incoming host IP/DNS lookup
5568 using the silc_socket_host_lookup and thus does not block
5569 the server anymore. Affected file silcd/server.c.
5571 * Completed the multi-thread support for SILC Scheduler in
5572 the lib/silcutil/silcschedule.c.
5574 * Fixed the configure.in.pre to detect the pthread correctly
5577 * Fixed a deadlock in silc_task_queue_wakeup in the file
5578 lib/silcutil/silctask.c.
5580 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5582 * Added new function silc_schedule_wakeup that is used in
5583 multi-threaded environment to wakeup the main thread's
5584 schduler. It needs to be used when a thread adds a new task
5585 or removes a task from task queues. After waking up, the
5586 scheduler will detect the task queue changes. If threads
5587 support is not compiled in this function has no effect.
5588 Implemented the wakeup mechanism to both Unix and WIN32
5589 systems. Affected files are lib/silcutil/silcschedule.[ch],
5590 lib/silcutil/unix/silcunixschedule.c and the
5591 lib/silcutil/win32/silcwin32schedule.c.
5593 * Added new function silc_task_queue_wakeup to wakeup the
5594 scheduler by the specified task queue. Affected file
5595 lib/silcutil/silctask.[ch].
5597 * The silc_socket_host_lookup_start now wakes up the scheduler
5598 after adding the timeout task. Affected file is
5599 lib/silcutil/silcsockconn.c.
5601 * The silc_socket_host_lookup is synchronous now if the threads
5602 support is not compiled in. However, the callback is still
5603 called asyncronously through the scheduler, anyway. Affected
5604 file lib/silcutil/silcsockconn.c.
5606 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5608 * Added new function silc_socket_host_lookup to perform
5609 asynchronous IP and FQDN lookups for the socket connection.
5610 Affected files lib/silcutil/silcsockconn.[ch].
5612 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5614 * Added SILC_MUTEX_DEFINE to define the mutex on environments
5615 that may or may not compile the mutex support in.
5617 Changed the silc_mutex_alloc interface. It allocates the
5618 mutex now to the sent pointer and returns TRUE or FALSE.
5620 Affected file lib/silcutil/silcmutex.h.
5622 * Wrote the SILC Task Queue interface to support multi-threads.
5623 Affected file lib/silcutil/silctask.[ch].
5625 * Wrote the SILC Scheduler to support multi-threads. Affected
5626 file lib/silcutil/silcschedule.c.
5628 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5630 * Implemented the SILC Mutex API and SILC Thread API for WIN32
5631 in lib/silcutil/win32/.
5633 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5635 * Defined SILC Mutex API and SILC Thread API and implemented
5636 them for Unix. Affected files are
5637 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
5638 lib/silcutil/unix/silcunixmutex.c and
5639 lib/silcutil/unix/silcunixthread.c.
5641 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5643 * Fixed the silc_server_remove_clients_by_server's channel
5644 key re-generation. The hash table handling was incorrect
5645 and would not work with many channels. Affected file is
5648 * Fixed some memory leaks around the server code.
5650 * Rewrote the silc_server_get_users_on_channel to support IPv6
5651 based Client ID's. Affected file silcd/server.c.
5653 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
5654 specification. However, a separate document must be written
5655 to define the detailed signing procedure and the payload
5656 associated with the flag. Defined the flag to the
5657 lib/silccore/silcchannel.h as well.
5659 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5661 * Changed the dynamic tables to static size tables in the
5662 lib/silccrypt/silchmac.c.
5664 * Removed GCC dependencies from the code. A patch by cras.
5666 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5668 * Do not show the error "Error receiving packet bla bla"
5669 in server if it really was not an error (-2 means that reading
5670 is pending). Affected file silcd/server.c.
5672 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5674 * Fixed a possible crash in silc_server_remove_clients_by_server
5675 in silcd/server.c. Fixed there also some memory leaks.
5677 * Fixed the silc_idlist_replace_client_id. It could replace
5678 wrong key in the hash table. Affected file silcd/idlist.c.
5680 * Do not check whether there are global users on the channel
5681 if the channel->global_users is FALSE. Affected functions
5682 silc_server_remove_from_one_channel and
5683 silc_server_remove_from_channels in silcd/server.c. Also,
5684 do not check if the removed client is local as we can be
5685 sure that global client was not removed from the channel
5686 and checking for global users is not needed.
5688 * The silc_server_remove_clients_by_server now re-generates
5689 the channel keys correctly for those channels that had
5690 clients removed from them. Affected file silcd/server.c.
5692 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5694 * Found the reason of random crashes in the server. We weren't
5695 ignoring the SIGPIPE signal (which can be sent in write())
5696 and it crashed the server. Affected file silcd/silcd.c.
5698 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5700 * Assure that sock->user_data is not NULL in the function
5701 silc_server_packet_send in silcd/packet_send.c.
5703 * Disconnect the remote connection if it could not be added
5704 to any ID lists in the server. The affected file is
5707 * Check in silc_server_packet_send[_real/dest] that the
5708 socket is not disconnecting and ignore the data if it is.
5709 Affected file silcd/packet_send.c.
5711 * Define inline to __inline on native WIN32 compilation.
5712 Affected file includes/silcwin32.h.
5714 * Added some explicit type casts for inline code since MSVC
5715 require them. Affected files lib/silcutil/silcbuffer.h,
5716 lib/trq/silcdlist.h and lib/trq/silclist.h.
5718 * Print warning in log files from now on if the packet
5719 decryption fails. Affected file silcd/server.c.
5721 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5723 * Changed the `say' client operation's interface to accept
5724 new `type' argument to indicate the type of the message sent
5725 by the library. The application may filter the library's
5726 messages according the type. The affected file is the
5727 lib/silcclient/silcapi.h.
5729 * Added two new functions to lib/silcclient/silcapi.h:
5730 silc_client_del_client and silc_client_del_client_by_id.
5731 Affected file lib/silcclient/idlist.c.
5733 * Moved the clientincludes.h from includes/ to silc/ and
5734 serverincludes.h from includes/ to silcd/.
5736 * The modes for the CMODE and CUMODE are now passed as
5737 uint32 for application with COMMAND_REPLY. The affected
5738 file is lib/silcclient/command_reply.c.
5740 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5742 * /WHOIS without arguments shows client's own information.
5743 Affected file lib/silcclient/command.c.
5745 * Changed PING to not accept any arguments. The specs
5746 says that client can ping only the connected server so
5747 requiring an argument is not needed. Affected file is
5748 lib/silcclient/command.c.
5750 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5752 * Fixed a fatal bug in private message sending and reception
5753 encryption and decryption when using private message keys.
5754 The implementation was incorrect and did not follow the
5755 specification. It causd that some of the message were
5756 lost since it did not use the sending and receiving keys
5757 as the protocol suggests. This has been fixed and will cause
5758 incompatibilities with older clients when sending private
5759 message encrypted with private message keys. Affected files
5760 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
5761 and various other in Irssi SILC Client.
5763 Added `responder' boolean argument to the functions
5764 silc_client_add_private_message_key[_ske] to indicate when
5765 the key is added as responder or initiator of the key
5768 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5770 * Removed the silc_ske_check_version function and created
5771 a SilcSKECheckVersion callback. Added also a function
5772 silc_ske_set_callbacks that is now used to set all SKE
5773 callbacks. The callback functions are not given to
5774 the SKE functions anymore, but this function is used to
5777 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
5779 * Added `silc_version' argument to the silc_client_alloc
5780 to define the version of the application for the library.
5781 The library will use the version string to compare it
5782 against the remote host's (usually a server) version
5783 string. Affected file lib/silcclient/silcapi.h
5785 * Added the KE protocol context to Key Agreement context
5786 in client library so that we can abort the SKE if it
5787 is in process when we get timeout. Affected file is
5788 lib/silcclient/client_keyagr.c.
5790 * Do not resolve the client ID forever if it returns in the
5791 first time that such client does not exist. This was done
5792 for example with private message. Affected file is
5793 lib/silcclient/client_prvmsg.c.
5795 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5797 * Do not add regex.h for WIN32. The affected file
5798 includes/silcincludes.h.
5800 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
5801 not work yet 100%. It generates the DLL's automatically
5802 when compiling with --with-win32 under cygwin.
5804 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5806 * lib/contrib/regex.c is not compiled on WIN32.
5808 * Added silc_net_get_socket_opt function to the
5809 lib/silcutil/silcnet.h.
5811 * Added includes/silcwin32.h for WIN32 specific includes
5814 * Do not use ptime structure or any of the posix process
5815 functions on WIN32 in lib/silccrypt/silrng.c.
5817 * Added silc_gettimeofday to provide generic function
5818 for struct timeval on all platforms. Added the function
5819 to lib/silcutil/silcutil.h.
5821 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5823 * Moved the lib/silccore/silcsockconn.[ch] to the utility
5824 library as they clearly belong there. As a plus side we
5825 can make the actual socket connection routines platform
5828 Added also new generic function silc_socket_read and
5829 silc_socket_write (that used to be silc_packet_[read/write].
5830 The implementation of these are platform specific.
5832 * Added WIN32 specific routines of silc_socket_[read/write]
5833 to lib/silcutil/win32/silcwin32sockconn.c.
5835 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5837 * Added preliminary support for native WIN32 compilation under
5838 cygwin (using the -mno-cygwin option for GCC) to the
5839 ./configure.in.pre. The --with-win32 now prepares the
5840 compilation for native WIN32.
5842 * Rewrote the SILC Scheduler interface in the file
5843 lib/silcutil/silcschedule.h. The scheduler is now context
5844 based and does not have anymore any global static scheduler.
5845 Moved the Unix scheduler to the lib/silcutil/unix/ directory
5846 and created lib/silcutil/win32 directory for WIN32 based
5849 * Added Unix specific network routines to the
5850 lib/silcutil/unix/silcunixnet.c and the old
5851 lib/silcutil/silcnet.c includes now only generic routines.
5853 Added WIN32 specific network routines to the
5854 lib/silcutil/win32/silcwin32net.c.
5856 * Added Unix specific utility functions from the
5857 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
5859 * Added WIN32 SILC Scheduler to the file
5860 lib/silcutil/win32/silcwin32schedule.c. The code is of course
5863 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5865 * Do not handle JOIN notify in the server if the target client
5866 is not registered (idata->registered == FALSE). The affected
5867 file is silcd/packet_receive.c.
5869 * Update the nickrec->founder in event_cumode in the Irssi SILC
5870 client. Affected file irssi/src/silc/core/silc-channels.c.
5872 * Fixed the CUMODE_CHANGE notify handling in the server when
5873 server and router are announcing their clients on channels.
5874 Now the mode changes are saved and notified correctly. The
5875 affected file is /silcd/packet_receive.c.
5877 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
5878 They really did not replace the cache entry in the ID Cache.
5879 Now they do that. Affected file silcd/idlist.c.
5881 * Fixed the KICK notify handling in the Irssi SILC client to
5882 update the channel records so that the kicked client does not
5883 appear to be on the channel. The affected file is
5884 irssi/src/silc/core/silc-channels.c.
5886 * Always update the conn->current_channel when executing command
5887 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
5889 * Fixed the KILL notify handling in Irssi SILC client to remove
5890 the killed client on all channels.
5892 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5894 * Fixed the silc_parse_command_line to remove extra spaces
5895 from the start and end of the arguments. Affected file is
5896 lib/silcutil/silcutil.c.
5898 * Cancel and free any active protocol in the function
5899 silc_server_close_connection. Affected file silcd/server.c.
5901 * Cancel and free any active protocol in the function
5902 silc_client_close_connction. Affected file is
5903 lib/silcclient/client.c.
5905 * Do not execute the KILL command for clients that are in
5906 history (ie. they are not in the network). Affected file is
5909 * Fixed KILL notify handling, client does not crash anymore.
5910 Affected file irssi/src/silc/core/silc-channels.c.
5912 * Reduced the default packet buffer size from 2048 to 1024 in
5913 lib/silccore/silcpacket.c.
5915 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
5916 counter to the SKE context that is incresed when the SKE library
5917 performs async operation outside the library. If the outside
5918 process frees the SKE context and FREED status will be set
5919 and the library will detect after the sync operation that the
5920 libary is freed. The affected files are
5921 lib/silcske/silcske[_status].[ch].
5923 * Resolve the client entry information in the function
5924 silc_client_channel_message to assure that NULL pointer is not
5925 passed as client entry to the application. */
5927 * Fixed the task timeout calculation to assure that there is
5928 never negative timeouts. The affected file is
5929 lib/silcutil/silcschedule.c.
5931 * Fixed the channel user mode notification sending in server.
5932 It was sent point-to-point to the router (or to server by router)
5933 but it needs to be destined to a channel. The routines now
5934 supports sending the channel user mode notifys to the channels
5935 when announcing clients and channels. Affected files are
5936 silcd/server.c and silcd/packet_receive.c.
5938 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
5939 It did not actually replace the old channel entry in the cache.
5940 Affected file lib/silcclient/client_notify.c.
5942 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5944 * Fixed a possible crash in silc_packet_send_prepare. It now
5945 assures always that there is enough space in the buffer and
5946 at the tail area of the buffer (for MAC).
5948 Fixed the inbound buffer reallocation in silc_packet_read.
5949 It was old code and did not handle the reallocation correctly.
5952 The affected file is lib/silccore/silcpacket.c.
5954 * Fixed buffer overflow in silc_parse_nickname in the file
5955 lib/silcutil/silcutil.c.
5957 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5959 * make install generates new server keys only if there is not
5962 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5964 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
5965 Added check that if the NOREPLY is set then we will not send
5966 the away message. This avoids infinite loop of away messages
5967 if both clients are away. The affected file is
5968 lib/silcclient/client_prvmsg.c.
5970 * Fixed client crash if /NICK was given without arguments.
5971 Affected file lib/silcclient/command.c.
5973 * Server does not send the invite list in INVITE command back
5974 to the client if the list was not altered. Added this notion
5975 to the protocol spec as well. Affected file silcd/command.c.
5977 Fixed possible crash in INVITE command by checking the
5978 value of silc_server_get_client_route command.
5980 * Fixed the INVITE notify type handling. The arguments are now
5981 taken in correct order and client does not crash. The affected
5982 file is irssi/src/silc/core/silc-channels.c.
5984 Removed the "Inviting xxx to channel" message from the
5985 client library away and let the application handle it.
5986 Affected file lib/silcclient/command.c. Added that message
5987 to Irssi SILC client's message formats.
5989 * Fixed CMODE command crash in client. It now checks the
5990 amount of arguments correctly and does not crash. The affected
5991 file is lib/silcclient/command.c.
5993 * Do not create new channel automatically in silc_channels_join
5994 but check whether the channel by that name already exists.
5995 Affected file irssi/silc/core/silc-channels.c.
5997 * Do not send the SERVER_SIGNOFF to router if the disconnected
5998 entity was the router. Affected file silcd/server.c.
6000 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
6001 SILC client as it was missing from there.
6003 Added the handling of the KICK notify to the Irssi SILC client
6004 as it was missing. Added "you have been kicked" message to
6005 Irssi SILC client's message modules formats.
6007 Added the handing of the KILL notify to the Irssi SILC client
6008 as it was missing. Added the kill message module formats
6011 The affected file is irssi/src/silc/core/silc-channels.c.
6013 * The router did not save the channel mode the server announced.
6014 Affected file silcd/packet_receive.c.
6016 * Fixed a possible crash in INFO command in server. If the
6017 server did not provide the server info it crashed. Affected
6018 file silcd/command.c.
6020 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6022 * Fixed the GETKEY command in the server to check also the
6023 global list. Otherwise the GETKEY would not work correctly
6024 in normal SILC server. Affected file silcd/command.c.
6026 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6028 * Fixed GETKEY crash, it crashed if the command did not succseed.
6030 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6032 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
6033 is now real and not just an macro interface to GMP.
6035 Removed the entire GMP from the source tree and imported new
6036 NSS MPI library instead. Reason for removing GMP is that it is
6037 extremely large and compiles extremely slow. The NSS MPI
6038 is only a few files and compiles in less than 10 seconds.
6039 The speed is also about the same as GMP. The MPI is imported
6040 to lib/silcmath/mpi.
6042 If the system has GMP installed we will still use the GMP.
6043 If it is not then the NSS MPI will be compiled.
6045 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6047 * Merged a long nickname (127 characters long) crash bugfix from
6048 Irssi CVS tree. Affected file irssi/src/core/misc.c.
6050 * Merged a freed memory reference bugfix from Irssi CVS tree.
6051 Affected file irssi/src/core/commands.c.
6053 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6055 * Added the server's public key sving and verification to the
6056 server when performing the SKE. This was missing and the
6057 remote server's (or router's) public key was accepted without
6058 checking whether we have it previously or trust it at all.
6059 Affected file silcd/protocol.c.
6061 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6063 * Check in the silc_server_timeout_remote if protocol is active
6064 and make sure that the protocol's final callback is called so
6065 that all memory if freed. Affected file silcd/server.c.
6067 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6069 * silc_server_whois_send_reply crashed the server if the nickname
6070 was 127 characters long. Affected file silcd/command.c.
6072 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6074 * Added sanity check to the silc_server_new_client. If the hostname
6075 is provided inside username then check that the provided hostname
6076 really is the same as the resolved one. If the hostname was not
6077 resolved then check it from the public key. Affected file is
6078 silcd/packet_receive.c.
6080 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
6081 if the server disconnected us and the connection is not valid
6082 anymore. Affected file irssi/src/silc/core/silc-channels.c.
6084 * Moved the silc_client_[chmode|chumode|chumode_char] away from
6085 the library to the lib/silcutil/silcutil.[ch].
6087 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6089 * Close log file after open. Affected file
6090 lib/silcutil/silclog.c.
6092 * Check whether sock == NULL in silc_client_send_packet and return
6093 if it is. Affected file lib/silcclient/silcclient.c.
6095 * Check rec->entry == NULL in the Irssi SILC Client before
6096 sending the channel message. Affecte file is
6097 irssi/src/silc/core/silc-servers.c.
6099 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6101 * Merged a splitted window bugfix from Irssi CVS tree. The
6102 affected file is irssi/src/fe-text/textbuffer-view.c.
6104 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
6105 It did not print nickname.
6107 * Improved the distributions system a bit.
6109 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6111 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
6112 irssi/src/fe-text/gui-window.c.
6114 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
6115 to in-active server. The affected file is
6116 irssi/src/silc/core/client_ops.c.
6118 * Resolve the client in USERS command reply if the entry does
6119 not have username resolved. The affected file is
6120 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
6121 command to WHOIS command to really resolve stuff. The USERS
6122 is not used any more in any critical section so WHOIS can
6123 be used even though it might be slower than IDENTIFY.
6125 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
6128 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6130 * Changed the protocol API a bit more consistent in the
6131 lib/silccore/silcprotocol.[ch].
6133 * Changed the following headers to ROBODoc format:
6135 lib/silccore/silcpayload.h
6136 lib/silccore/silcprotocol.h
6137 lib/silccore/silcsockconn.h
6139 All core library headers are now formatted.
6141 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6143 * Fixed a bug in Irssi SILC client; do not show that you are
6144 server/router operator if you really are not. Affected file is
6145 irssi/src/silc/core/client_ops.c.
6147 * Renamed silc_command_free_payload to silc_command_payload_free.
6148 Affected file lib/silccore/silccommand.h
6150 * Added silcmath.h to include the prototoypes of various routines
6151 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
6154 * Changed the following headers to ROBODoc format:
6156 lib/silccore/silcchannel.h
6157 lib/silccore/silccommand.h
6158 lib/silccore/silcid.h
6159 lib/silccore/silcidcache.h
6160 lib/silccore/silcmode.h
6161 lib/silccore/silcnotify.h
6162 lib/silccore/silcpacket.h
6163 lib/silcmath/silcmath.h
6165 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6167 * Added checking to the server code not to start the server if
6168 ciphers and stuff are not configured properly. Affected files
6169 silcd/serverconfig.[h] and silcd/server.c.
6171 * Changed the layout of the header files of the public interfaces
6172 in the SILC libraries. The new layout supports ROBODoc
6173 documentation tool (and some others) so that it is easy to create
6174 a library reference manual. All the other headers and source
6175 code must still follow the CodingStyle document. Also source
6176 code must not include these ROBODoc stuffs, only the headers.
6177 Furthermore, all public interface headers must now be named
6178 by using `silc' prefix, example: silcapi.h, silccipher.h.
6179 Some files were renamed due to this. All the other headers
6180 must not be used as public interfaces. I will update the
6181 CodingStyle document later. Changed following headers, so far:
6183 lib/silcclient/silcapi.h
6184 lib/silccore/silcauth.h
6185 lib/silccore/silcprivate.h
6186 lib/silccrypt/silcdh.h
6188 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6192 * Removed silc_client_packet_send_flush from the client library
6193 as it is not needed. Affected file lib/silcclient/client.[ch].
6195 * Added printing of message of unresolved authentication method
6196 to the Irssi SILC client. Added it to the module formats.
6197 Removed the same message from the client library.
6199 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6201 * Added new distribution feature, DISTLABEL. Every distribution
6202 can define own preprocessor label that can be used in the
6203 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
6204 file distributions, acconfig.h.pre and prepare.
6206 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6208 * Added Makefile.defines_int to include the actual definitions
6209 for Makefile.defines.in. Tested the new distribution system,
6210 created distributions and tested installation.
6212 * Added AWAY message printing to the Irssi SILC client. Added
6213 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
6215 * Added SCONNECT command to call the SILC's CONNECT command.
6216 Cannot use CONNECT directly since Irssi uses that internally.
6217 Affected file irssi/src/silc/core/silc-servers.c.
6219 Added ACTION local command. It is same as ME command but takes
6220 the channel as mandatory argument.
6222 Rewrote some of the Irssi's help files to suite for SILC
6225 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6227 * Added Makefile.defines[.in] that should for now on be included
6228 in all Makefile.am file in the source tree. That file includes
6229 all common compilation definitions for SILC source tree.
6231 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6233 * Minor changes to the ./prepare script to change the package
6234 name according the distribution name to the configure.in.
6236 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6238 * Created new distribution system. Added file `distributions'
6239 that defines all the distributions that can be created out of
6240 the SILC source tree. The ./prepare script now reads that
6241 file to determine how to prepare the distributions. The
6242 first argument to the ./prepare is the name of the distribution
6243 and second is the version of the distribution. If given
6244 without arguments it creates the default (toolkit) distribution
6245 with the default version (defined in ./prepare).
6247 All Makefile.am files that are subject to the distributions
6248 are now named as Makefile.am.pre. These are ./Makefile.am
6249 and lib/Makefile.am. Others may be changed later.
6251 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6253 * Added invite list, ban list, some key management and connection
6254 error message printing to module formats in the Irssi SILC client.
6256 * Added new silc_client_set_away_message to set the away message
6257 that is back to the person who sent private message. The
6258 affected file lib/silcclient/silcapi.h and the
6259 lib/silcclient/client_prvmsg.c.
6261 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6263 * Fixed the private message sending in the Irssi SILC client,
6264 added local command KEY to the Irssi SILC client.
6266 Added key management and key agreement message formats to the
6267 irssi/src/fe-common/silc/module-formats.[ch].
6269 Added USERS (alias WHO) printing, server/router operator
6270 indication and LIST command printing to the module formats.
6272 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6274 * Fixed channel joining notify handling, cumode notify handling
6275 from Irssi SILC client.
6277 * Added SILC specific module-formats to the Irssi SILC client so
6278 that SILC specific message hilighting, colors etc is possible.
6279 Affected file irssi/src/fe-common/silc/module-formats.[ch].
6281 Added channel mode, channel user mode, actions, notices,
6282 whois and whowas printing to the the module-formats.c.
6284 * Fixed a bug in channel deletion in the server. The channel
6285 is not left to the cache even if the channel founder auth mode
6286 is set when there are no users anymore on the channel. Affected
6287 file silcd/server.c.
6289 * The silc_net_localhost now resolves the entire hostname including
6290 the domain name. Affected file lib/silcutil/silcnet.c.
6292 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6294 * Changed the ask_passphrase client operation to be ascynchronous.
6295 It has now a completion callback and a context that the
6296 application must call after it has got the passphrase from
6297 the user. Affected files lib/silcclient/silcapi.h,
6298 lib/silcclient/protocol.c, lib/silcclient/command.c and
6301 Added SilcAskPassphrase callback that the application calls
6302 to deliver the passphrase to the library.
6304 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
6305 The public key verification and especially a certificate
6306 verification is asynchronous procedure.
6308 Added new SILC_SKE_STATUS_PENDING status to indicate the
6309 request is pending and a callback will be called to finalize
6312 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
6313 indicate that remote end did not send its public key (or
6314 certificate), even though we require it. Added check for this
6315 condition in the SKE. This was a security bug, now fixed.
6317 Defined new SilcSKEVerifyCbCompletion callback that is called
6318 when the verification process is completed.
6320 The affected files lib/silcske/silcske_status.h and
6321 lib/silcske/silcske.[ch].
6323 * Changed the verify_public_key client operation to be async
6324 as well. Defined SilcVerifyPublicKey callback that is used to
6325 indicate the success of the public key verification process.
6327 Changed the server and client to use the new async client
6330 * Changed the Irssi SILC client's internal scheduler to be called
6331 twice as many times as it used to be. As a result the client
6332 should be a bit faster now. Affected file is
6333 irssi/src/silc/core/silc-core.c.
6335 * Added support to Irssi SILC client of asynchronous public key
6336 verification and passphrase inquiry. Affected file is
6337 irssi/src/silc/core/silc-core.c.
6339 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6341 * Do not say "You have left channel %s" in client library.
6342 Moved it to the application. Affected files are
6343 lib/silcclient/command.c and silc/client_ops.c.
6345 * Fixed silc_client_get_clients. Command context was not
6346 duplicated and was freed memory in the callback. Affected
6347 file lib/silcclient/idlist.c.
6349 * Do not say "you are now talking..." on JOIN command in the
6350 client library. The appliation must handle it.
6352 * Do not say ".. changed topic to" in command reply in the
6353 client libary. The application must handle it.
6355 * Fixed TOPIC command sending in the client library.
6357 * Fixed a memory leak in silc_client_command_free in the file
6358 lib/silcclient/command.c.
6360 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6362 * Imported a modified version of Irssi client to the source tree.
6363 The Irssi will be used to create a new client called
6364 Irssi SILC. Imported to irssi/.
6366 Added silc_core_init_finish function to the Irssi. Affected
6367 file irssi/configure.in.
6369 A lot changes in the Makefile.ams around the irssi tree.
6371 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6373 * Do not rehash if the new size is same as the old size of the
6374 hash table, in the silc_hash_table_rehash*. The affected file
6375 lib/silcutil/silchashtable.c.
6377 * Replaced hash_table_del_by_context calls from the server
6378 (when channel->user_list and client->channels) to the
6379 hash_table_del as it is sufficient and faster.
6381 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6383 * Added silc_hash_table_list, silc_hash_table_get and the
6384 SilcHashTableList structure to provide an alternative way to
6385 traverse the hash table. The affected files are
6386 lib/silcutil/silchashtable.[ch].
6388 * Changed the server's idlist routines to use the hash table
6389 routines to optimize the code.
6391 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6393 * Replaced the client entry's `channel' list and channel entry's
6394 `user_list' list to hash tables for optimized lookup. Changed
6395 the code to use the hash table interface around the code.
6396 Affected file lib/silcd/idlist.[ch].
6398 * Added `auto_rehash' boolean argument to the function
6399 silc_hash_table_alloc to indicate whether the hash table should
6400 auto-rehash when it thinks is appropriate time. It will
6401 increase the hash table size if the there is twice as much
6402 entries in the table than the size of the table, and will
6403 decrease the size if there are twice as less entries than
6404 the size of the table.
6406 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6408 * Fixed silc_xxx_get_supported to not crash at some circumstances.
6410 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6412 * silc_idcache_purge_by_context deletes the entry now by context
6413 as it is supposed to do. Affected file lib/silccore/idcache.c.
6415 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
6416 client is not anymore valid (WHOWAS givens the info) and not
6417 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
6419 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6421 * Removed the `data' and `data_len' arguments from the ID Cache
6422 interfaces and added `name' argument. ID Cache does not handle
6423 anymore the binary data only a names associated with given ID.
6425 * When hashing a Client ID with silc_hash_id the entire ID is
6426 not hashed anymore, instead only the hash of the Client ID is
6427 hashed. This way we can access the Client ID from the cache
6428 with Client ID but with the hash of the ID (which is a hash of
6429 the nickname) as well without any difference in performance.
6431 Added also silc_idcache_find_by_id_one_ext to do one on one
6432 searching when we have the actual ID. Added also function
6433 silc_hash_client_id_compare. The affected files are
6434 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
6436 * When hashing the name associated with a ID it is always done
6437 in lowercase. This way we can access the cache without worrying
6438 about case-sensitivity, even though, for example nicknames are
6441 * Fixed a bug in server with channel message sending. It put
6442 wrong ID type as destination ID. The affected file
6443 silcd/packet_send.c.
6445 * silc_idcache_del_by_context now deletes from all hash tables
6446 by context. Affected file lib/silccore/idcache.c.
6448 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6450 * Changed the client library to use the new ID Cache interface.
6451 Changes around the source tree.
6453 * Added silc_hash_table_rehash_ext to rehash with specific
6454 hash function. Affected file lib/silcutil/silchashtable.[ch].
6456 * Added silc_hash_string_compare to compare two strings in the
6457 hash table. Affected file lib/silcutil/silcutil.[ch].
6459 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6461 * Added new function silc_idcache_del_by_context into the
6462 lib/silccore/idcache.[ch].
6464 * Changed the server's ID list routines to use the new ID Cache
6465 interface. Changes around the source tree.
6467 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6469 * Added silc_hash_table_del[_by_context]_ext functions in to the
6470 lib/silcutil/silchashtable.[ch].
6472 Removed silc_hash_table_find_all* routines and added new
6473 silc_hash_table_find_foreach to replace them.
6475 Added silc_hash_table_replace_ext function as extended
6476 replacing function. Separated the simple hash table interface
6477 from the extended hash table interface in the file
6478 lib/silcutil/silchashtable.h.
6480 * Fixed minor bugs and changed it to use some of the new
6481 hash table functions in lib/silccore/idcache.c
6483 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6485 * Added new function silc_hash_table_find_all to return all keys
6486 in the hash table by the specified key. As the hash table is
6487 collision resistant it also makes it possible to have several
6488 duplicate keys in the hash table. This function may be used to
6489 find all of the keys from the hash.
6491 Added user_context arguments to the SilcHashFunction,
6492 SilcHashCompare and SilcHashDestructor to deliver user specified
6495 Added new fuctions silc_hash_table_find[_all]_ext to do
6496 extended lookup with specified hash and compare functions and
6497 specified user contexts.
6499 Added new function silc_hash_table_add_ext to add the key
6500 with specified hash function and user context.
6502 Added new function silc_hash_table_foreach to traverse all
6503 entrys in the hash table. Added SilcHashForeach callback
6506 Added new function silc_hash_table_del_by_context to delete
6507 the entry only if the context associated with the key matches.
6509 Affected files are lib/silcutil/silchashtable.[ch].
6511 * Removed silc_hash_[server/client/channel]_id and added just
6512 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
6513 silc_hash_id_compare to compare two ID's using as the hash table
6514 comparison function. Added also silc_hash_data to hash
6515 binary data and silc_hash_data_compare to compare it.
6517 * Removed silc_idlist_find_client_by_hash as it is not needed
6518 anymore. Affected file silcd/idlist.[ch].
6520 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
6521 to use internally the SilcHashTable. The new ID Cache is a lot
6522 faster than the old one. Some of the ID Cache interface was also
6523 rewritten and obsolete and stupid functions were removed.
6525 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6527 * Added entry_count field to the SilcHashTable to keep the number
6528 of the entries in the table. Implemented the function
6529 silc_hash_table_rehash. Added new function
6530 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
6532 Fixed a minor bug in silc_hash_table_free.
6534 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
6535 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
6536 into the lib/silcutil/silcutil.[ch].
6538 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6540 * Implemented a collision resistant hash table into the
6541 lib/silcutil/silchashtable[ch]. See the header and the source
6542 for the SilcHashTable API.
6544 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6546 * Merged dotconf version 1.0.2 into lib/dotconf.
6548 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6550 * Do not compile anything in lib/silcsim/* if the SIM support
6551 is not enabled. The tree should now compile without problems
6554 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6556 * Compiled the SILC under cygwin. Compiled and tested briefly
6557 without problems. More tests needed. The SIMs didn't compile
6560 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
6562 * Fixed possible crash in silc_get_username in the
6563 lib/silcutil/silcutil.c.
6565 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6567 * Fixed a va_arg in silc/client_ops.c.
6569 * Oops, RC5 routines were named AES and caused some problems
6570 when not using SIM's. Affected file lib/silccrypt/rc5.c.
6572 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6574 * Added new SilcIDIP structure into the lib/silccore/id.h and
6575 replaced the old `ip' fields from all SILC ID's to that type.
6576 This is a step towards IPv6 support.
6578 The silc_id_get_len takes now the ID as an extra argument.
6579 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
6580 both IPv4 and IPv6 based ID's.
6582 The affected files are lib/silccore/id.[ch] and other files
6583 around the tree using these routines.
6585 * Removed the ID length arguments in server from various
6586 silc_server_send_notify_* routines -> they are not needed
6589 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6591 * Fixed memory leak in silc_encode_pem_file in the file
6592 lib/silcutil/silcutil.c.
6594 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6596 * Check minor version as well in the SKE. Affected files are
6597 silcd/protocol.c and lib/silcclient/protocol.c.
6599 * Added --identifier option to the server so that an identifier
6600 can be when creating the public key for the server. Affected
6601 file is silcd/silcd.c.
6603 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
6604 lib/silccrypt/silcpkcs.c.
6606 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6608 * Register default ciphers and stuff when using -C option with
6609 the server. Affected file sildc/silcd.c.
6611 * Put back the servers public key filename format, it is better
6612 than the new one. For now, the client keys are saved with the
6613 new filename format. The affected file silc/client_ops.c.
6615 * Implemented the Cipher API for the rest of the ciphers that
6616 did not implement it or implemented it the wrong way.
6618 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6620 * Register default ciphers and stuff when using the -S option
6621 in the client. Affected file silc/silc.c. Same also when
6622 creating new key pair with -C option.
6624 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6626 * Fixed the silc_verify_public_key client operation function to
6627 save the public keys differently. The fingerprint is now
6628 used as filename and not the hostname. This way also the
6629 client keys are saved uniquely and not with hostnames. The
6630 affected file is silc/client_ops.c.
6632 * Trimmed the silc_hash_fingerprint function to remove extra
6633 whitespaces from the end of the fingerprint. The affected
6634 file is lib/silccrypt/silchash.c.
6638 * Added silc_cipher_register_default function to register all
6639 default ciphers. It can be used when configuration files
6640 does not exist and the application does not want any specific
6641 ciphers in any specific order.
6643 The SilcDList is now used as silc_cipher_list dynamically
6644 allocated cipher list. Removed the static list all together
6645 and now all ciphers must be allocated to the dynamic list.
6646 The silc_cipher_alloc routine was changed to check only the
6649 All silc_cipher_* routines that used to return int returns
6652 The affected files lib/silccrypt/silccrypt.[ch].
6654 * The same thing was done to silc_hash_* as for silc_cipher_*
6655 routines. Affected files lib/silccrypt/silchash.[ch].
6657 * The same thing was done to silc_pkcs_* as for silc_cipher_*
6658 routines. Affected files lib/silccrypt/silcpkcs.[ch].
6659 Added also silc_pkcs_[un]register[_default] functions.
6660 Removed the data_context from the PKCS API.
6662 * Added silc_hmac_register_default function to register default
6663 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
6664 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
6665 to unregister all hmacs at once.
6667 * Register the default ciphers, hash functions, PKCSs and HMACs
6668 if client's configuration file does not exist. The affected
6671 * The client did not load the hash functions from the SIM
6672 modules at all. Added support for this. Affected file is
6673 silc/clientconfig.c.
6675 * When decoding public key with silc_pkcs_public_key_decode, check
6676 the supported algorithm only if PKCS are registered. Affected
6677 file lib/silccrypt/silcpkcs.c. The same was done with the
6678 silc_pkcs_private_key_decode.
6680 * Fixed the SILC List routines to keep the list always in order.
6681 It used to change the list's order when traversing the list but
6682 not it preserves the order. Affected file lib/trq/silclist.h.
6684 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6686 * Added the client library to use the SilcSocketConnection's
6687 reference counter (by silc_socket_dup) to prevent the bug that
6688 the socket object may be freed underneath async operation.
6690 * The name resolv library checking fixes in the configure.in.pre.
6693 * Created new version of the protocol drafts for future
6694 development. The -03 drafts are the ones that will be changed
6695 in the trunk now and the -02 will remain as they are.
6697 * Send list of CUMODE notifys to the router when announcing
6698 the channel users to the router. Affected file silcd/server.c.
6699 If the router receiving channel founder CUMODE for a channel
6700 that already has channel founder it will send CUMODE notify
6701 to the sender to remove the channel founder rights from the
6702 announced client. Affected file silcd/packet_receive.c.
6704 * The CUMODE notify may now use Server ID as well as the entity
6705 who changes the mode. Updated protocool specs.
6707 * Updated INSTALL and README files.
6709 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6711 * New web pages in the http://silc.pspt.fi. The pages was
6716 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6718 * Implemented the [DenyConnectin] config section in the server.
6719 Added silc_server_config_denied_conn to check whether incoming
6720 connection is denied. Affected file silcd/serverconfig.[ch].
6722 * Do not check the ports when checking the incoming configuration
6723 data if the port is 0, meaning any. Affected file is
6724 silcd/serverconfig.c.
6726 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6728 * Fixed buffer overflow in silc_string_compare in the file
6729 lib/silcutil/silcutil.c.
6731 * Fixed double free in silc_server_command_leave in the file
6734 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6736 * Fixed the version checking in the server. Affected file is
6739 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6741 * Fixed the configuration data fetching when accepting new
6742 connections in the server. Affected file silcd/server.c.
6744 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6746 * Added `sender_entry' argument to the function
6747 silc_server_packet_relay_to_channel so that we can check
6748 whether some destination actually belongs to the same route
6749 the sender belongs (ie, we must not resend the packet to the
6750 sender). Affected file silcd/packet_send.[ch].
6752 * Added `servername' field to the SilcClientEntry in the server
6753 to hold the name of the server where client is from. Affected
6754 file is silcd/idlist.h.
6756 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6758 * Moved the channel message encrypting in the router betwen
6759 router connections from silc_server_channel_message to the
6760 silc_server_packet_relay_to_channel since we want to check
6761 whether we have anybody channel before encrypting anything.
6762 Affected files silcd/packet_[receive/send].c.
6764 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6766 * Fixed the [AdminConnection] server config section to support
6767 multiple entries. Affected file silcd/serverconfig.c.
6769 * Added support into the server to check the validity of the
6770 incoming connection before executing any KE or authentication
6773 * The connection configuration is now saved to the KE and
6774 connection auth protocol contexts and not fetched anymore in
6775 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
6777 * The local hosts listenning address and port is also resolved
6778 now when starting the server. We want to have the socket object
6779 to include the real address and port for the listener. Added
6780 new function silc_net_check_local_by_sock into the files
6781 lib/silcutil/silcnet.[ch].
6783 * Fixed a broadcast bug in server -> do not broadcast if we
6786 * Fixed a routing bug. Do not route broadcast packets ever.
6787 Broadcast packets must be processed always and not routed since
6788 they may be destined to some other host than yourself and thus
6789 would get routed without no good reason. Affected file is
6792 * Added function silc_server_config_is_primary_route to check
6793 whether primary router connection has been configured (a router
6794 configuration that we are initiating). If there is not, we
6795 will assume that there is only two routers in the SILC network
6796 and we will use the incoming router connection as our primary
6797 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
6799 * Changed the order of the broadcasting. Broadcast _after_ the
6800 packet has been processed not before. Affected file is
6803 * Fixed a [ClientConnection] parsing bug. The port was never
6804 parsed correctly thus resulting to port 0. Affected file
6805 silcd/serverconfig.c.
6807 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
6808 argument and did not set the broadcast packet flag. Affected
6809 file silcd/packet_send.c. Fixed same bug in the function
6810 silc_server_send_notify as well.
6812 * If we receive NEW_ID packet for our own ID in the server, ignore
6815 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6819 * Removed the nickname from the Private Message Payload.
6820 Updated the code and the protocol specs.
6822 * Updated protocol specs for submitting to the IETF.
6824 * Tweaked the Random Number Generator a bit. Affected file
6825 lib/silccrypt/silcrng.c. Exported a new function
6826 silc_rng_[global]_add_noise which can be used to add more
6829 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6831 * Do not parse packets with different timeout when protocol
6832 is active -> may cause problem with rekey. Affected file
6835 * When server receives signoff notify it must not create
6836 new channel key if the client is on any channels since the
6837 sender of the signoff notify will create it.
6839 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6841 * Added printing of error messages during SKE protocol from the
6842 failure packet sent by server during SKE. Affected file
6845 * Removed the client's failure_callback handling with timeout
6846 and handle it immediately when received.
6848 * The SKE library returned wrong type in SUCCESS and FAILURE
6849 packets. They must be 32 bit MSB not 16 bit MSB.
6851 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6853 * Ok, rewrote the logic of the re-key and now it seems to work.
6854 I tested it on high traffic with frequent re-keys without
6855 problems. Added hmac_receive (and renamed hmac to hmac_send)
6856 in SilcClientConnection in lib/silcclient/client.h and
6857 in SilcIDListData in silcd/idlist.h. Also, removed the
6858 SilcPacketParserContext's cipher and hmac fields as they are
6859 not needed anymore and actually caused some problems when
6860 the ciphers and hmac's changed underneath the packet parser.
6862 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6864 * If re-key protocol is active then process the incoming packets
6865 synchronously since we must assure that icoming packets encrypted
6866 with the old key is processed before the new keys is set to
6867 use. This is true other packets than for REKEY packets.
6868 Affected file silcd/server.c. The same was done to client library
6869 as well, affected file lib/silcclient/client.c.
6871 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6873 * Fixed bug in client and server to accept the force send if
6874 the packet is send from silc_[server/client]_packet_process
6875 function. Otherwise the packets are never delivered, oops.
6877 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6879 * Disable force sending of packets when REKEY protocol is active.
6880 We must assure that no packet is sent directly when rekey is
6881 performed. All packets must be sent through packet queue.
6882 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
6883 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
6884 function is silc_[server/client]_packet_send_real to check
6887 * Replaced the SIM paths from example config files to
6888 /usr/local/modules. Also, make install creates now
6889 /usr/local/silc/logs directory to hold all the SILC server
6892 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6894 * Made the configure.in.pre work on Solaris. Patch by salo.
6896 * Made all ciphers compatible with non-x86 machines. Defined
6897 CBC mode macros into lib/silccrypt/ciphers_def.h.
6899 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6901 * Fixed the make install.
6903 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6905 * When MAC computation fails the silc_packet_decrypt returned 0
6906 even though it was supposed to return -1. Fixed this. The
6907 affected file is lib/silccore/silcpacket.c.
6909 * Do not replace the config files in /etc/silc (in make install)
6910 if they already exist. Affected file ./Makefile.am.
6912 * Do not send re-key packets immediately but through packet queue.
6913 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
6915 * Changed silc_net_check_host_by_sock to return FALSE if the
6916 IP/DNS could not be resolved. Though, it returns the IP address
6917 now even if it could not resolve it (but returns also FALSE).
6918 Affected file lib/silcutil/silcnet.[ch].
6920 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6922 * Added silc_pkcs_decode_identifier to decode the public key's
6923 identifier. Affected file lib/silccrypt/silpkcs.[ch].
6924 Added also silc_pkcs_free_identifier. Added also new context
6925 SilcPublicKeyIdentifier.
6927 * Added -S option to the silc client. It is used to dump the
6928 contents of the specified public key file.
6930 * Changed the PKCS api to return the public key length when
6931 setting the public key.
6933 * Fixed a fatal bug in the public and private key file loading.
6934 Affected file lib/silccrypt/silcpkcs.c.
6936 * Execute the packet parsing for client with zero (0) timeout
6937 if the protocol is active. Affected file silcd/server.c.
6939 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6941 * Made the key generation options to the silcd program. Added
6942 -C option, equivalent to client's option.
6944 * Added new [ServerKeys] config section to the server. It
6945 configures the server's public and private key.
6947 * Defined generic Public Key Payload into the protocol
6948 specification to send specific type of public keys and
6951 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
6952 public key or certificate.
6954 * Implemented the GETKEY command to the server and to the
6955 client library and on user interface.
6957 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6959 * Made preliminary `make install' work.
6961 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6963 * Added SilcServerRekey context into silcd/idlist.h.
6965 * Added the PFS support as defined in the specification to the
6966 SKE protocol. Affected files lib/silcske/*.c.
6968 * Added `ske_group' field to the SilcServerRekey context to hold
6969 the number of the SKE group that is used with PFS in re-key.
6970 Affected file silcd/idlist.h.
6972 * Added PFS re-key support to the server. Affected file is
6975 * Added silc_protocol_cancel to cancel execution of the next
6976 state of the protocol. Affected file is
6977 lib/silccore/silcprotocol.[ch].
6979 * Added the re-key support with and without PFS to the client
6980 library. Re-key is performed once in an hour, by default.
6982 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
6983 Added silc_client_rekey_callback and silc_client_rekey_final.
6984 Affected files are lib/silcclient/protocol.[ch] and
6985 lib/silcclient/client.[ch].
6987 * Removed the `hmac_key' and `hmac_key_len' fields from the
6988 SilcClientConnection structure; not needed. Affected file is
6989 lib/silcclient/client.h.
6993 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6995 * Do not ask whether user wants to use the negotiated private key
6996 for private messages, just use it. Affected file is
6997 silc/local_command.c.
6999 * Added `send_enc_key' and `enc_key_len' fields to the
7000 SilcIDListData structure since they are needed in the re-key
7001 phase. Affected file is silcd/idlist.[ch].
7003 * Implemented the simple re-key protocol into the server.
7004 Affected files silcd/server.c and silcd/protocol.[ch]. The
7005 re-key will be performed once in an hour, by default.
7007 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
7008 Added silc_server_rekey, silc_server_rekey_callback and
7009 silc_server_rekey_final.
7011 * Removed Tunneled flag from the protocol. Updated the code
7012 and the specifications.
7014 * Adde `pfs' field to the SilcIDListData to indicate whether
7015 the PFS is to be performed in the re-key. Affected file is
7018 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7020 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
7021 int64 of at least the xintXX size. If void * is less that 4
7022 bytes uint32 * will be used. Defined bool as boolean.
7024 * Changed _ALL_ unsigned long and unsigned int to uint32,
7025 unsgined short to uint16 in the source tree.
7027 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
7028 not handle clients that has entry->data.registered == FALSE.
7029 They are not in the network anymore. Affected file is
7032 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7034 * Implemented the sending of the SERVER_SIGNOFF notify in the
7035 server. Affected file is silcd/server.c.
7037 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
7038 Added also silc_notify_payload_encode_args into the
7039 lib/silccore/silcnotify.[ch].
7041 * Implemented ther SERVER_SIGNOFF notify handling in the server.
7042 Affected file silcd/packet_receive.c.
7044 * Implemented the SERVER_SIGNOFF notify handling in the client
7045 library. Affected file lib/silcclient/client_notify.c. Also,
7046 implemnted the printing of the SERVER_SIGNOFF info to the
7047 application. Affected file silc/client_ops.c.
7049 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
7050 if the deleting was successful. Affected file silcd/idlist.[ch].
7052 * Added support for public key authentication in the connection
7053 authentication protocol in the client library. Affected file
7054 lib/silcclient/protocol.c.
7056 * Changed the server's silc_idlist_get_clients_by_* interface
7057 to support already allocated array so that new entries may be
7058 added to pre-allocated array. Affected file silcd/idlist.[ch].
7059 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
7060 and command replies.
7062 * All command reply functions in the server now calls the
7063 pending command callback even if error occured. This way the
7064 error will be delivered to the client as well. Affected files
7065 silcd/command.c and silcd/command_reply.c.
7067 * Fixed INFO command to return local server's info if no server
7068 was provided. Affected file lib/silcclient/command.c.
7070 * Removed RESTART command for good. Updated the code and the
7073 * Rewrote parts of the task system. It is a bit simpler now.
7074 Removed unsued task priorities. The affected files are
7075 lib/silcutil/silctask.[ch].
7077 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7079 * Moved the USERS printing from the library to the application.
7080 Affected files lib/silcclient/command.c and silc/client_ops.c.
7082 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7086 * Added channel key re-key support. The re-key is perfomed
7087 only by the router and is done once in an hour. Added `rekey'
7088 field to the SilcChannelEntry in the server. Affected files
7089 silcd/server.c and silcd/idlist.h.
7091 * Added silc_task_unregister_by_context into the file
7092 lib/silcutil/silctask.[ch].
7094 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7096 * Added SILC_UMODE_GONE mode to indicate when the client is not
7097 present in the SILC network. Added also support to the local
7098 command AWAY that will set this mode. Added support of showing
7099 "xxx is gone" in WHOIS command. The USERS command shows the
7100 gone status as well.
7102 * Fixed setting server and router operator privileges in the
7103 server's UMODE command. Affected file silcd/command.c.
7105 * Merged the SKE KE1 and KE2 payloads into one payload. The
7106 new KE payload is equivalent to the old KE2 payload.
7108 Cleaned up the SKE Start Payload parsing. It now uses the
7109 simple buffer unformatting to do the parsing. A lot faster
7112 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
7113 to the SKE that is used to indicate whether both of the SKE
7114 parties should perform authentication. By default only the
7115 responder performs authentication. By setting this flag also
7116 the initiator must do authentication. By default it is unset
7117 since in normal SKE case, client to server connection, only
7118 the responder should do authentication. When doing SKE between
7119 two clients both should perform authentication. Updated the
7120 code and the protocol specs.
7122 * A little fix to IDENTIFY command in the server. Search the
7123 client first by hash not nickname. Affected file is
7126 * Fixed the silc_client_close_connection to support closing
7127 the client to client connections wihtout deleting too much
7128 data. Affected file lib/silcclient/client.c.
7130 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
7131 are received if protocol used to be active but is not anymore
7132 the application would crash due to NULL pointer dereference.
7133 Affected files silcd/server.c and lib/silcclient/client.c.
7135 * Added `hash' field to the SilcClientConnection to include
7136 the hash function negotiated in the SKE protocol.
7138 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
7139 to set the channel founder authentication data. A client can
7140 claim the founder rights later by providing the authentication
7141 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
7142 This way the channel founder can regain the channel founder
7143 privileges even it is left the channel. This works only on
7144 local server and the client must be connected to the same
7145 server to be able to regain the founder rights. Updated the
7146 protocol specs accordingly.
7148 Added support to the CMODE command in the client to set the
7149 founder auth data. Read the README to see how to set it.
7151 Added support to the CUMODE command to claim the founder
7152 rights. Read the README to see how to do it.
7154 Added support for the founder authentication to the Channel
7155 Entry in the server. Affected file silcd/idlist.h.
7157 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
7158 server's CMODE command. Affected file silcd/command.c.
7160 * Added the following new functions into lib/silccore/silcauth.[ch]:
7161 silc_auth_get_method and silc_auth_get_data.
7163 * The server now saves the remote hosts public key to the
7164 SilcIDListData pointer. Affected file silcd/protocol.c.
7166 * The normal server now does not remove the channel entry from
7167 the cache if the founder authentication data is set. It used
7168 to remove it if the founder was the last one on the channel on
7169 the server and left the channel. The auth data is saved and
7170 if the channel is re-joined later the old entry is used with
7171 the old auth data. Affected files silcd/command_reply.c and
7174 * Removed the `pkcs' field from the SilcIDListData structure
7175 in the server; it is not used. Affected file silcd/idlist.h.
7177 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7179 * Fixed packet processing on slow links. Partial packets were
7180 never re-processed because the incoming data buffer was cleared
7181 by the application. Application must not directly clear the
7182 sock->inbuf, the packet processing routines handle it. Fixed
7183 this in client library and in server.
7185 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7187 * Fixed the WHOIS and IDENTIFY send reply function to really
7188 check whether to send list or just one entry. Affected file
7191 * Cleaned up the LEAVE command's channel key distribution. The
7192 affected file silcd/command.c.
7194 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
7195 can enforce the channel mode as well. In that case the ID
7196 includes the ID of the server. The code now enforces the
7197 mode change if the router have different mode than the server.
7199 * The notify client operation with CMODE_CHANGE notify can now
7200 return NULL client_entry pointer if the CMODE was not changed
7201 by client. Application must check for this.
7203 * Added <Server ID> argument to INFO command to support server
7204 info fetching by Server ID.
7206 * Added silc_server_announce_get_channel_users to get assembled
7207 packets of channel users of the specified channel. Affected
7208 file silcd/server.[ch].
7210 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
7211 was freed underneath the ID Cache.
7213 * Re-announce clients when the server received CHANNEL_CHANGE
7214 notify from the router. Affected file silcd/packet_send.c.
7216 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7218 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
7219 crashed since it did not handle the fact that there is no cipher
7220 called "3" and didn't check the error condition. Now fixed.
7222 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
7223 flag. It can be used to send message requests.
7225 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7227 * Implemented the RESTART command in the client.
7229 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
7230 notice type messages. Added notice printing to the user
7233 * The channel keys are not re-generated if the channel's mode
7234 is PRIVKEY, ie private key on the channel exists. Affected
7235 files silcd/server.c and silcd/command.c.
7237 * Fixed a little bug in channel message delivery when channel
7238 private keys are set in the server. Affected file is
7239 silcd/packet_send.c.
7241 * Changed the setting on channel->on_channel = TRUE from the
7242 silc_client_save_channel_key to the JOIN command reply. The
7243 key payload is not received if the private channel key is set.
7244 Affected file lib/silcclient/command_reply.c and the
7245 lib/silcclient/client_channel.c.
7247 * When the CMODE_CHANGE notify is sent and the channel private
7248 key mode is removed the channel key must be re-generated in
7249 other cells as well. Added this support for the router in the
7250 silcd/packet_receive.c.
7252 * Added new local command NOTICE to send notice message on
7253 channel. Affected file silc/local_command.[ch].
7255 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7257 * Added new local command ME to the client. It is used to send
7258 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
7259 some action. Affected file silc/local_command.[ch].
7261 * Changed channel_message and private_message client operations
7262 to deliver the message flags to the application. Added also
7263 the `flags' arguments to the silc_client_send_channel_message
7264 and silc_client_send_private_message functions. Affected file
7267 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7269 * Redefined the Private Message Payload to support private message
7270 keys and to support the new private message flags. Updated
7271 the protocol specs. Flags makes it possible to have for example
7272 CTCP style messages.
7274 * Added new type SilcPrivateMessagePayload and defined an API
7275 for it in the lib/silcclient/silcprivate.[ch].
7277 * Tested private message private keys successfully. Tested the
7278 private message key set, unset and list commands with the new
7281 * Redefined the Channel Message Payload to include the channel
7282 message flags (equal with private message flags) to support
7283 for example CTCP style messages.
7285 * Defined some of the message (for channel and private message)
7286 flags. Updated the protocol specs and added the flags to the
7287 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
7289 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7291 * Added SilcKeyAgreementStatus type to the key agreement routines
7292 to indicate the current status and error if one occured.
7293 The status types are defined in the lib/silcclient/silcapi.h.
7295 * Added new local command KEY that is used to set and unset private
7296 keys for channels, set and unset private keys for private messages
7297 with remote clients and to send key agreement requests and
7298 negotiate the key agreement protocol with remote client. The
7299 key agreement is supported only to negotiate private message keys,
7300 it currently cannot be used to negotiate private keys for channels,
7301 as it is not convenient for that purpose.
7303 * Fixed a minor pending callback setting bug in the function
7304 silc_client_get_client_by_id_resolve, now the function works.
7305 Affected file lib/silcclient/idlist.c.
7307 * Added function silc_net_get_local_port to get local bound
7308 port by socket. Added to lib/silcutil/silcnet.[ch].
7310 * Added `sockets' and `sockets_count' fields to the SilcClient
7311 object. They hold the sockets of the listenning sockets in
7312 the client. Listenning sockets may be for example the key
7313 agreement server. Affected file lib/silcclient/client.[ch].
7314 Added functions the silc_client_add_socket and the
7315 silc_client_del_socket. They are exported to the application
7318 * Added ~./silc/clientkeys to support other client's public keys.
7320 * Renamed verify_server_key client operation to verify_public_key
7321 and added one argument to indicate the type of the connection
7322 (server, client etc.).
7324 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7326 * Added silc_server_connection_auth_request to handle the
7327 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
7328 silcd/packet_receive.[ch].
7330 * Added silc_server_send_connection_auth_request into the
7331 silcd/packet_send.c to send the connection auth request packet.
7333 * Cleaned up the silcd/protocol.c a bit and fixed some memory
7336 * Fixed the public key authentication in responder side in the
7337 server. The `auth_data' pointer includes the SilcPublicKey
7338 not the path to the public key. Affected file silcd/protocol.c.
7340 * Implemented the public key authentication in the initiator side
7341 in the server. Affected file silcd/protocol.c.
7343 * Removed the [RedirectClient] config section from the server
7344 configuration. Is not needed and I don't want to implement it.
7346 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7348 * Cleaned up the CMODE command in the server. It now works
7349 correctly and supports all the modes defined in the protocol.
7350 Affected file is silcd/command.c.
7352 * Added `hmac_name' field to the SilcChannelEntry in the server
7353 to hold the default HMAC of the channel. It can be set when
7354 creating the channel (with JOIN command). Affected files
7357 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
7358 type to indicate the change of the current cipher and hmac
7359 on the channel. Client can safely ignore the <cipher> argument
7360 (if it chooses to do so) since the CHANNEL_KEY packet will
7361 force the channel key change anyway. The <hmac> argument is
7362 important since the client is responsible of setting the new
7363 HMAC and the hmac key into use.
7365 * Fixed the CMODE command in the client library as well.
7367 * Tested CMODE command in router environment successfully.
7369 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7371 * Show the version of the remote client (or server) when connecting
7372 to the server. It is logged to the log file. Affected file
7373 is silcd/protocol.c.
7375 * Fixed the KILLED notify handling in the client library. The
7376 client must be removed from all channels when receiving the
7379 Also, do not remove the client entry when giving the KILL
7380 command but when the KILLED notify is received.
7382 * Removed silc_idlist_find_client_by_nickname from the server.
7383 Not needed anymore. Affected files silcd/idlist.[ch].
7385 * Implemented the CHANNEL_CHANGE notify type handling to the
7386 server. Affected file silcd/server.c.
7390 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7392 * Added silc_server_send_notify_invite to send the INVITE
7393 notify between routers.
7395 * Implemented the INVITE command correctly to the server.
7397 * Implemented the INVITE notify type handling in the server.
7399 * Implemented the INVITE command to the client library and on the
7402 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7404 * Added function silc_server_get_client_resolve to find the
7405 client entry by ID from all ID lists and then resolve it
7406 (using WHOIS) if it cannot be found. Affected file is
7409 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7411 * Implemented the BAN command to the client library.
7413 * The JOIN command in the server now checks the invite list
7416 * Changed the silc_command_reply_payload_encode_va and the
7417 silc_command_payload_encode_va to support that if argument is
7418 NULL it ignores and checks the next argument. Affected file
7419 lib/silccore/silccommand.c.
7421 * Added silc_server_send_notify_ban to send the BAN notify
7422 type between routers.
7424 * Chaned the silc_notify_payload_encode to support that if
7425 argument is NULL it ignores and checks the next argument.
7426 Affected file lib/silccore/silcnotify.c.
7428 * Tested ban lists in router environment successfully.
7430 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7432 * Implemented BAN command to the server, in silcd/command.[ch].
7434 * Removed the BAN and INVITE_LIST modes from the CMODE command
7437 * Added function silc_string_match to regex match two strings.
7438 Affected files lib/silcutil/silcutil.[ch].
7440 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7442 * Redefined parts of the SilcChannelEntry in the server to support
7443 the new ban and invite lists.
7445 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7447 * Redefined the INVITE command. The same command can be used to
7448 invite individuals to the channel but also to manage the invite
7449 list of the channel (to add to and remove from the invite list).
7450 Updated the protocol specs.
7452 * Added new command SILC_COMMAND_BAN that can be used to manage
7453 the ban list of the channel. Updated the protocol specs.
7455 * Removed the channel modes: the SILC_CMODE_BAN and the
7456 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
7457 in the CMODE command. The equivalent features are now available
7458 using INVITE and BAN commands. Updated the protocol specs.
7460 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
7461 in the network about change in the current ban list. The notify
7462 type is not used by the client.
7464 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
7465 support the invite lists.
7467 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7469 * Added new function silc_string_regexify that converts string
7470 including wildcard characters into regex string that can
7471 be used by the GNU regex library. Added into the file
7472 lib/silcutil/silcutil.[ch].
7474 Added silc_string_regex_combine to combine to regex strings
7475 into one so that they can be used as one regex string by
7476 the GNU regex library. Added into the file
7477 lib/silcutil/silcutil.[ch].
7479 Added silc_string_regex_match to match two strings. It returns
7480 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
7482 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7484 * Imported GNU regex to the soruce tree into lib/contrib.
7485 Fixed some compiler warning from the regex.c.
7487 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7489 * Fixed MOTD command in the server to work in router environment.
7491 * Fixed the MOTD command in the client library to support
7492 the server argument in the command.
7494 * Added `nickname_len' argument to the silc_idlist_add_client
7495 in the server, as the `nickname' argument may be binary data
7498 * Added silc_idlist_get_channels to return all channels from
7501 * Implemented LIST command to the server. Affected file is
7504 * Implemented the LIST command to the client library and on the
7507 * Added [<user count>] argument to the LIST command reply.
7508 With private channels the user count is not shown.
7510 * Updated TODO and README.
7512 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7514 * The client entry's data.registered must be TRUE even with
7515 global client entry on global client list. The data.registered
7516 is used to check whether the client is anymore in the network,
7517 for example with WHOWAS command so it must be valid.
7519 * Fixed the WHOWAS command in the server. It now actually works
7520 in router environment. Added function into silcd/command_reply.c
7521 silc_server_command_reply_whowas_save.
7523 * Added silc_idlist_purge function to the silcd/idlist.c
7524 to periodically purge the ID Cache.
7526 * Fixed INFO command in the server. It works now in router
7527 environment. Added <server name> argument to the INFO command
7528 reply. Updated the protocol specs.
7530 * Fixed minor bug in silc_idcache_purge to not purge if the
7531 expire value is zero.
7533 * Fixed various bugs in WHOIS and IDENTIFY command handling as
7534 they were buggy because of the WHOWAS information.
7536 * Fixed local command MSG to handle the async resolving of
7537 the remote client properly. It used to fail the first MSG.
7538 Affected file silc/local_command.c.
7540 * Added `data_len' field to SilcIDCache context.
7542 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7544 * Update TODO. Todo in commands in the server.
7546 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7548 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
7549 used by routers as broadcast packet to inform other routers
7550 about the changed user mode.
7552 Implemented the notify handling in the server. Affected file is
7553 silcd/packet_receive.c. Added the function
7554 silc_server_send_notify_umode to the silcd/packet_send.[ch].
7556 * Added new generic Channel Payload and deprecated the New Channel
7557 Payload. The New Channel Payload is now the generic Channel
7560 * Added new argument `mode' to the silc_server_send_new_channel
7561 as it is required in the Channel Payload now.
7563 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
7564 and created a new and real SilChannelPayload to represent the
7565 new generic Channel Payload. Implemented the encode/decode
7566 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
7568 * Added silc_server_get_client_channel_list to return the list
7569 of channels the client has joined for WHOIS command reply.
7570 Affected file silcd/server.[ch].
7572 * Implemented the channel list sending in the WHOIS command reply
7573 in server and in the client.
7575 Implemented the channel list displaying on the user interface
7576 as well. Affected file silc/client_ops.c.
7578 * Added silc_channel_payload_parse_list to parse list of Channel
7579 Payloads. It returns SilcDList list of SilcChannelPayloads.
7580 Client for example can use this function to parse the list of
7581 channels it receives in the WHOIS command reply. The caller
7582 must free the list by calling silc_channel_payload_list_free.
7583 Affected files lib/silccore/silcchannel.[ch].
7585 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7587 * Added one new argument <user mode> to the WHOIS command reply
7588 to return the mode of the user in SILC. Updated the protocol
7591 Implemented it to the server and client.
7593 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7595 * Fixed the mode printing on the user interface on joining.
7596 Affected file silc/client_ops.c.
7598 * Implemented the UMODE command and user modes in general to the
7599 client library and to the user interface.
7601 * Implemented the UMODE command to the server.
7603 * The server now sends UNKNOWN_COMMAND error status if client sends
7604 unknown command. Affected file silcd/command.c.
7606 * All server commands now handle the command identifier the right
7607 way when sending the command reply to the client. The client can
7608 use to identify the command replies with the identifier.
7610 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7612 * Added silc_server_get_client_route to resolve the route to
7613 the client indicated by the client ID. Affected file is
7616 * Added silc_server_relay_packet as general function to relay
7617 packet to arbitrary destination. This deprecates functions
7618 like _send_private_message_key, _relay_notify etc. Affected
7619 file is silcd/packet_send.[ch].
7621 Removed silc_server_send_key_agreement,
7622 silc_server_send_private_message_key and
7623 silc_server_packet_relay_notify functions from the file
7624 silcd/packet_send.[ch].
7628 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
7629 server. Affected file silcd/packet_receive.[ch].
7631 * Implemented the KILL command to the client. Implemented the
7632 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
7633 Affected files lib/silcclient/command[_reply].c and
7634 lib/silcclient/client_notify.c. Implemented the KILL notify
7635 printing in the user inteface.
7637 * Fixed a lot silc_parse_nick memory leaks from the client
7638 library in the file lib/silcclient/command.c.
7640 * Changed the silc_server_send_notify_on_channels's `sender'
7641 argument from SilcSocketConnection to SilcClientEntry to
7642 check the sender as entry and not as connection object and not
7643 to send to the client provided as argument. The affected file
7644 is silcd/packet_send.[ch].
7646 * The notify packets that are destined directly to the client used
7647 to not to be processed by the server. Now changed that and the
7648 server processes all notify packets. After relaying the packet
7649 to the client the notify packet is processed in the server.
7651 * The silc_server_free_client_data now checks whether there is
7652 pending outgoing traffic for the client and purges the data to
7653 the network before removing the client entry.
7655 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7657 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
7658 an client is killed from the SILC Network. Updated the protocol
7661 Added new function silc_server_send_notify_killed to the
7662 silcd/packet_send.[ch].
7664 * Added function silc_server_packet_relay_notify to relay notify
7665 packets that are destined directly to a client. In this case
7666 the server does not process the notify packets but merely relays
7667 it to the client. Affected file silcd/packet_send.[ch].
7669 Added also silc_server_packet_process_relay_notify to check
7670 whereto relay the notify. Affected file is
7671 silcd/packet_receive.[ch].
7673 * Implemented the KILL command to the server.
7677 * Added the backup schema desgined last fall to the protocol
7678 specs for everyone to see. The specification is in the
7679 *-spec-xx.txt draft and the packet type definitions for the
7680 backup routers is in *-pp-xx.txt draft. Thusly, added also
7681 new packet type SILC_PACKET_CELL_ROUTERS.
7683 * A big security problem in the implementation discovered. The
7684 signoff of an client did not cause new channel key generation
7685 which it of course should've done. The channel keys must be
7686 always re-generated when client leaves (or signoffs) the channel.
7687 The silc_server_remove_from_channels funtion now handles
7688 the channel key re-generation.
7690 * Added `sender' argument to the silc_server_send_notify_on_channels
7691 to not to send the client provided as argument. Affected file
7692 silcd/packet_send.[ch].
7694 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7696 * Implemented OPER and SILCOPER commands into the server and
7699 * Added silc_auth_verify and silc_auth_verify_data to verify
7700 the authentication directly from the authentication payload.
7701 It supports verifying both passphrase and public key based
7702 authentication. Affected file lib/silccore/silcauth.[ch].
7704 * Added `hash' field to the SilcIDListData structure. It is the
7705 hash negotiated in the SKE protocol. Affected file is
7708 * Slight redesigning of the SilcAuthPayload handling routines.
7709 Do not send SilcPKCS but SilcPublicKey as argument.
7711 * Implemented the public key authentication support to the
7712 serverconfig. The public key is loaded from the provided path
7713 and saved as authentication data to void * pointer. Thus,
7714 changed the unsigned char *auth_data to void *auth_data;
7716 * Fixed SHUTDOWN command to send the reply before the server
7717 is shutdown. :) Affected file silcd/command.c.
7719 * Fixed fatal bug in CONNECT command. The hostname was invalid
7720 memory and server crashed. Affected file silcd/command.c.
7722 * Fixed fatal bug in CLOSE command. The server_entry became
7723 invalid but was referenced later in the command. Affected file
7726 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7728 * Fixed fatal bug in failure packet handling. Server ignored
7729 the failure and thus crashed when it came.
7733 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7735 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
7736 that the command may be executed only once in (about) 2 seconds.
7737 The old SILC_CF_LAG flag is same but allows command bursts up
7738 to five before limiting.
7740 Added the support for CF_LAG and CF_LAG_STRICT flags to the
7741 server code. Various commands now includes the CF_LAG_STRICT
7742 flag to disallow any kind of miss-use of the command.
7744 * Fixed the silc_buffer_unformat to not to allocate any data
7745 if the length of the data is zero. It used to allocate the
7746 length + 1. Affected file lib/silcutil/silcbuffmt.c.
7748 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7750 * Changed the format of AdminConnection configuration section
7751 in the server. Added username of the admin to the format.
7752 Affected files silcd/serverconfig.[ch].
7754 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
7755 to return admin configuration data by host, username and/or
7758 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7760 * Implemented WHOWAS command to the server. Added the functions:
7762 silc_server_command_whowas_parse,
7763 silc_server_command_whowas_send_reply,
7764 silc_server_command_whowas_from_client and
7765 silc_server_command_whowas_from_server
7767 * Added <Client ID> argument to the WHOWAS command reply. Updated
7768 the protocol specs accordingly.
7770 * Implemented WHOWAS command and command_reply to the client
7773 Implemented the WHOWAS printing on the user interface.
7775 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7777 * Added new argument to the WHOWAS command reply, the real name.
7778 It is an optional argument. Updated the protocol specs.
7780 * Added SilcIDCacheDestructor callback that is registered when
7781 the SilcIDCache is allocated. The callback is called when
7782 an cache entry in the ID Cache expires, or is purged from the
7783 cache. Added into lib/silccore/idcache.[ch].
7785 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
7786 to destruct the client entries when the cache entry expires.
7787 Other ID Cache's in server and in the client library ignores
7790 * If the ID Cache entry's `expire' field is zero then the entry
7791 never expires. Added boolean `expire' argument to the
7792 silc_idcache_add function in the lib/silccore/idcache.[ch].
7793 If it is TRUE the default expiry value is used.
7795 * Added silc_server_free_client_data_timeout that is registered
7796 when client disconnects. By default for 5 minutes we preserve
7797 the client entry for history - for WHOWAS command.
7799 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7801 * Added support to the server to enforce that commands are not
7802 executed more than once in 2 seconds. If server receives
7803 commands from client more frequently, timeout is registered
7804 to process the commands. Affected file silcd/command.c.
7805 Added new function silc_server_command_process_timeout.
7807 * Changed NICK_NOTIFY handling in client library to check that
7808 if the client's nickname was changed, so there is no need to
7809 resolve anything from the server.
7811 * Removed error printing from the WHOIS and IDENTIFY commands.
7812 If error occurs then it is ignored silently in the client library.
7813 The application, however, may map the received error to
7814 human readable error string. The application currently maps
7815 the NO_SUCH_NICKNAME error to string.
7817 * Made the command status message public to the application. Moved
7818 them from lib/silcclient/command_reply.c to
7819 lib/silcclient/command_reply.h. The application can map the
7820 received command status to the string with the
7821 silc_client_command_status_message function.
7823 * Added check to the server to check that client's ID is same
7824 as the Source ID in the packet the client sent. They must
7827 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7829 * Added dist-bzip hook to the Makefile.am to make bzip2
7830 compressed distributions.
7832 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7834 * Server now enforces the maximum length for the nickname and
7835 the channel as protocol specification dictates. 128 bytes for
7836 nickname and 256 bytes for channel name.
7838 * Moved the WHOIS printing to the application. The client libary
7839 does not print out the WHOIS information anymore, the application
7840 must do it. Renamed silc_client_command_reply_whois_print to
7841 the silc_client_command_reply_whois_save.
7843 The client's idle time is also sent to the application now, and
7844 the idle is shown on screen.
7846 * Added silc_client_command_reply_identify_save to save the
7847 received IDENTIFY entries.
7849 * Do not check for channel private keys in message sending and
7850 reception if the channel does not have the PRIVKEY mode set.
7851 Affected file lib/silclient/client_channel.c.
7853 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7855 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
7856 just surfaced after chaning the JOIN procedure.
7858 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7860 * Added silc_client_get_clients_by_list to get client entries
7861 from Client ID list, that is returned for example by JOIN
7862 and USERS command replies. The application should use this
7863 function for example when JOIN command reply is received to
7864 resolve the clients already on the channel (library does not
7865 do that anymore as USERS command reply is not used in the JOIN
7866 procedure anymore). Affected files lib/silcclient/silcapi.h and
7867 lib/silcclient/idlist.c.
7869 * JOIN command reply and USERS command reply returns now SilcBuffer
7870 pointers instead of unsigned char pointers when returning
7871 the client list and mode list.
7873 * Added <Client ID> argument to the JOIN command reply, mainly
7874 for the server to identify for which client the command was
7875 originally sent. Updated protocol specs accordingly.
7877 * Added SilcDlist private_key pointer to the SilcChannelEntry
7878 in the client to support the channel private keys. Affected
7879 file is lib/silcclient/idlist.h.
7881 * Added SilcChannelPrivateKey argument to the function
7882 silc_client_send_channel_message so that application can choose
7883 to use specific private ke if it wants to. If it is not provided,
7884 the normal channel key is used, unless private keys are set.
7885 In this case the first (key that was added first) is used
7886 as the encryption key.
7888 * Implemented the support for channel private key handling.
7889 Implemented the following functions:
7891 silc_client_add_channel_private_key,
7892 silc_client_del_channel_private_keys,
7893 silc_client_del_channel_private_key,
7894 silc_client_list_channel_private_keys and
7895 silc_client_free_channel_private_keys
7897 Affected file lib/silcclient/client_channel.c.
7899 * Added the support for the private keys in the channel message
7900 sending and encryption and in the message reception and
7901 decryption. Affected funtions are
7902 silc_client_send_channel_message and silc_client_channel_message.
7904 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7906 * Added SKE's key verify callback to the client library's
7907 KE protocol context. Affected files lib/silcclient/protocol.[ch].
7909 * Removed the statement that server (or router) must send USERS
7910 command reply when joining to the channel so that the client
7911 knows who are on the channel. Instead, the client list and
7912 client's mode list is now sent in the JOIN command reply to the
7913 client who joined channel. This is better solution.
7915 * Added function silc_server_get_users_on_channel and function
7916 silc_server_save_users_on_channel to the silcd/server.[ch].
7918 * Removed function silc_server_command_send_users from the
7921 * Do not show topic on the client library anymore. The topic is
7922 sent in the command reply notify to the application and the
7923 application must show the topic now.
7925 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7927 * Added client searching by nickname hash into the IDENTIFY and
7928 WHOIS commands in the server as they were clearly missing from
7929 them. Affected file is silcd/command.c.
7931 * Fixed a bug in private message receiving in the client library.
7932 The remote ID was freed and it wasn't supposed, now it is
7935 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7937 * Minor fix to the channel payload; allocate the data area, as it
7938 needs to be of specific length.
7940 * If the key agreement port is zero then the operating
7941 system will define the bound port. Affected files are
7942 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
7944 * Added new function silc_channel_payload_decrypt into the file
7945 lib/silccore/silcchannel.[ch].
7947 * Moved the channel message etc, check from silc_packet_decrypt
7948 to applications. The library calls now a generic
7949 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
7950 when the packet is either normal or special. This was done to
7951 allow more wide range of checking that was not allowed when
7952 the code was in library. Now applications can do virtually any
7953 checks to the packet and return to the library the decision how
7954 the packet should be processed. Affected files are
7955 lib/silccore/silcpacket.[ch].
7957 Added silc_server_packet_decrypt_check to the server and
7958 silc_client_packet_decrypt_check to the client library.
7960 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
7961 to send with specified source and destination information.
7963 * Channel message delivery between routers was broken after the
7964 channel key distribution was fixed earlier. The channel key
7965 was used be to distributed to other routers as well which is not
7966 allowed by the protocol. Now this is fixed and channel keys
7967 really are cell specific and the channel message delivery between
7968 routers comply with the protocol specification.
7970 * Fixed various commands in server to check also the global list
7971 for the channel entry and not just the local list. The affected
7972 file silcd/command.c.
7974 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7976 * Added assert()s to buffer formatting and unformatting routines
7977 to assert (if --enable-debug) when error occurs. Affected
7978 file: lib/silcutil/silcbuffmt.c.
7980 * Changed to auto-reconnect to check whether the remote host is
7981 router and register the re-connect timeout if it is. It used
7982 to check that whether we are normal server, but router must do
7983 auto-reconnect with another router as well. Affected file
7986 * Removed the [<key len>] option from CMODE command as the cipher
7987 name decides the key length, nowadays. See the defined ciphers
7988 from the protocol specification.
7990 * Added [<hmac>] option to the CMODE command to define the HMAC
7991 for the channel. Added SILC_CMODE_HMAC channel mode.
7993 * Added [<hmac>] option for the JOIN command so that user can
7994 select which HMAC is used to compute the MACs of the channel
7997 * Added Hmac field to the Channel Message Payload. The integrity
7998 of plaintext channel messages are now protected by computing
7999 MAC of the message and attaching the MAC to the payload. The
8000 MAC is encrypted. Now, it is clear that this causes some
8001 overhead to the size of the packet but rationale for this is that
8002 now the receiver can verify whether the channel message decrypted
8003 correctly and also when private keys are set for the channel the
8004 receiver can decrypt the packet with several keys and check from
8005 the MAC which key decrypted the message correctly.
8007 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
8008 lib/silccrypt/silccipher.[ch].
8010 * Added silc_hash_len to return the digest length into the
8011 lib/silcrypt/silchash.[ch].
8013 * Rewrote parts of Silc Channel Payload interface in the
8014 lib/silccore/silcchannel.[ch]. The encode function now also
8015 encrypts the packet and parse function decrypts it.
8017 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8019 * Fixed a minor formatting bug in the SKE's key material processing.
8020 It actually might have processed the keys wrong way resulting
8023 * Redefined the mandatory HMAC algorithms and added new algorithms.
8024 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
8025 and hmac-md5 truncated to 96 bits. The mandatory is now
8026 hmac-sha1-96. Rest are optional (including the one that used
8027 to be mandatory). Rationale for this is that the truncated HMAC
8028 length is sufficient from security point of view and can actually
8029 make the attack against the HMAC harder. Also, the truncated
8030 HMAC causes less overhead to the packets. See the RFC2104 for
8033 * Added new [hmac] configuration section. The SKE used to use
8034 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
8035 is of course wrong. The official names that must be proposed in
8036 the SKE are the ones defined in the protocol specification
8037 (hmac-sha1-96 for example). The user can configure any hmac
8038 using any hash function configured in the [hash] section. At
8039 least, the mandatory must be configured.
8041 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
8043 * Added HMAC list to the SKE proposal list. It has now both
8044 hash algorithm list and HMAC list. This makes the protocol
8045 incompatible with previous versions. The SKE now seems to work
8046 the way it is supposed to work, for the first time actually.
8048 * Defined plain Hash algorithms to the protocol specification.
8051 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8053 * Implemented support for key agreement packets into the server.
8054 Added functions silc_server_key_agreement and
8055 silc_server_send_key_agreement. Other than these functions,
8056 server has nothing to do with this packet.
8058 * Added support for private message key packets into the server.
8059 Added functions silc_server_private_message_key and
8060 silc_server_send_private_message_key.
8064 * Changed the silc_[client|server]_protocol_ke_set_keys to be
8065 called in the protocol's final callback instead in the END
8066 protocol state. This makes a little more sense and in the same
8067 time in client we can use the same protocol routines for normal
8068 key exchange and to key agreement packet handling as well.
8070 * Added to both client's and server's KE protocol context the
8071 SilcSKEKeyMaterial pointer to save the key material. We will
8072 bring the key material to the protocol's final callback by doing
8073 this. The final callback must free the key material.
8075 * Added SKE's packet_send callback into client's KE protocol
8076 context so that the caller can choose what packet sending function
8077 is used. This way we can use different packet sending when
8078 doing normal SKE when doing key agreement packet handling (in
8079 the key agreement packet handling we do not want to encrypt
8082 * Implemented the responder side of the key agreement routines
8083 in the client. The client can now bind to specified port and
8084 accept incoming key negotiation. The key material is passed
8085 to the application after the protocol is over.
8087 * Implemented the processing of incoming Key Agreement packet
8088 in the client. Added function silc_client_key_agreement to
8091 * Implemented the intiator side of the key agreement routines
8092 in the client. The client can now initiate key agreement with
8093 another remote client. The key material is passed to the
8094 application after the protocol is over.
8096 * Created client_keyagr.c to include all the key agreement
8099 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
8100 SILC_TASK_CALLBACK except that it is not static.
8102 * Created client_notify.c and moved the Notify packet handling
8103 from the client.[ch] into that file.
8105 * Created client_prvmsg.c and moved all private message and
8106 private message key routines from the client.[ch] into that file.
8108 * Create client_channel.c and moved all channel message and
8109 channel private key routines from the client.[ch] into that file.
8111 * Changed silc_client_get_client_by_id_resolve to resolve with
8112 WHOIS command instead of IDENTIFY command, in the file
8113 lib/silclient/idlist.c.
8115 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8117 * Implemented the SKE's responder side to the Client library.
8119 * When FAILURE is received to the protocol do not trust it
8120 blindly. Register a timeout to wait whether the remote closes
8121 the connection as it should do it, only after that process the
8122 actual failure. This was changed to both client and server.
8124 * Added client_internal.h to include some of the structures
8125 there instead of client.h in lib/silcclient/.
8127 * Added function silc_task_unregister_by_callback to unregister
8128 timeouts by the callback function.
8130 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8132 * Some "Incomplete WHOIS info" errors has been appearing on the
8133 log files. Took away the entry->userinfo check from WHOIS
8134 reply sending. The entry->userinfo is now " " if client did not
8135 provide one. I thought this was fixed earlier but something
8136 is wrong still. Let's see if the error still appears.
8138 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8140 * Fixed a minor bug in the login when the channel key is
8141 re-generated in the server. It used to generate the key in
8142 wrong order and thus caused problems in the channel traffic.
8144 * Fixed a minor bug in channel key distsribution after
8145 KICK command. The key was not sent to the router even though
8148 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8150 * Added silc_ske_process_key_material_data as generic routine
8151 to process any key material as the SILC protocol dictates. The
8152 function is used by the actual SKE library but can be used by
8153 applications as well. This relates to the private message keys
8154 and the channel private keys since they must be processed the
8155 same way the normal SILC session keys. The protocol dictates
8156 this. Affected files: lib/silcske/silcske.[ch].
8158 Added also silc_ske_free_key_material to free the
8159 SilcSKEKeyMaterial structure.
8161 * Defined silc_cipher_set_key function to set the key for
8162 cipher without using the object's method function. The affected
8163 files: lib/silccrypt/silccipher.[ch].
8165 * Implemented silc silc_client_add_private_message_key,
8166 silc_client_add_private_message_key_ske,
8167 silc_client_del_private_message_key,
8168 silc_client_list_private_message_keys and
8169 silc_client_free_private_message_keys functions in the
8172 Added functions silc_client_send_private_message_key to send
8173 the Private Message Key payload and silc_client_private_message_key
8174 to handle incoming Private Message Key payload.
8176 * Added Cipher field to the Private Message Key payload to set
8177 the cipher to be used. If ignored, the default cipher defined
8178 in the SILC protocol (aes-256-cbc) is used.
8180 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8182 * Removed lib/silcclient/ops.h file.
8184 Redefined parts of the SILC Client Library API. Created new
8185 file silcapi.h that deprecates the ops.h file and defines the
8186 published Client Library API. Defined also private message key
8187 API and channel private key API into the file.
8189 This is the file that the application must include from the
8190 SILC Client Library. Other files need not be included by
8191 the application anymore.
8193 * Added new key_agreement client operation callback and also
8194 defined the Key Agreement library API for the application.
8196 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8198 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
8199 is used by clients to request key negotiation between another
8200 client in the SILC network. If the negotiation is started it
8201 is performed using the SKE protocol. The result of the
8202 negotiation, the secret key material, can be used for example
8203 as private message key.
8205 Implemented the Key Agreement payload into the files
8206 lib/silccore/silauth.[ch].
8208 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8210 * Redefined ciphers for the SILC protocol. Added some new ciphers
8211 and defined the key lengths for the algorithms. Changed the
8212 code accordingly. The default key length is now 256 bits.
8214 * Fixed SKE key distribution function silc_ske_process_key_material
8215 when the key length is more than 128 bits. The default key
8216 length in SILC is now 256 bits.
8218 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
8219 to indicate unsupported algorithm.
8221 * Renamed rijndael.c to aes.c and all functions as well.
8223 * Fixed a long standing channel key setting bug in client library.
8224 Weird that it has never surfaced before.
8226 * Fixed bug in channel deletion. If the entire channel is removed
8227 then it must also delete the references of the channel entry
8228 from the client's channel list as the client's channel entry and
8229 the channel's client entry share same memory.
8231 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8233 * Implemented CONNECT and SHUTDOWN commands in the client.
8235 * Implemented CLOSE command to the client.
8237 * Added the function silc_idlist_find_server_by_name into the
8238 files silcd/idlist.[ch].
8240 Added the function silc_idlist_find_server_by_conn into the
8241 files silcd/idlist.[ch].
8243 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8245 * DIE command was renamed to SHUTDOWN. Updated the both code
8248 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
8249 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
8251 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
8254 * Added function silc_server_create_connection function to create
8255 connection to remote router. My server implementation actually
8256 does not allow router to connect to normal server (it expects
8257 that normal server always initiates the connection to the router)
8258 so the CONNECT command is only good for connecting to another
8261 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8263 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
8264 or some other client was kicked from the channel.
8266 Implemented the handling of the notify type to both client
8269 Implemented silc_server_send_notify_kicked to send the KICKED
8270 notify. It is used to send it to the server's primary router.
8272 * Implemented the KICK command into server and client.
8274 * Added `query' argument to the silc_idlist_get_client function
8275 to indicate whether to query the client from server or not if
8278 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
8279 to indicate that the client is not channel founder.
8283 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8285 * Removed the rng context from SilcPacketContext structure and
8286 changed that the packet routine uses the Global RNG API.
8288 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8290 * Added support for quit message that client can "leave" on the
8291 channel when it quits the SILC. It is ditributed inside the
8292 SILC_NOTIFY_TYPE_SIGNOFF notify type.
8294 Added silc_server_free_client_data that will take the
8295 signoff message as argument.
8297 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
8299 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8301 * Updated parts of the protocol specification to keep it up
8304 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8306 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
8307 payloads in one packet.
8309 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
8310 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
8311 use now the new List flag.
8313 * Also deprecated the following packet types: REPLACE_ID,
8314 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
8316 * Added list support for Notify packet in server.
8318 * Added silc_server_send_notify_channel_change to send the
8319 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
8320 the silc_server_send_replace_id.
8322 * Added silc_server_send_notify_nick_change to send the
8323 NICK_CHANGE notify type. Deprecates the function
8324 silc_server_send_replace_id.
8326 * Added silc_server_send_notify_join to send the JOIN notify type.
8327 Deprecates the function silc_server_send_new_channel_user.
8329 * Added silc_server_send_notify_leave to send LEAVE notify type.
8330 Deprecates the function silc_server_send_remove_channel_user.
8332 * Added silc_server_send_notify_cmode and
8333 silc_server_send_notify_cumode to send CMODE and CUMODE notify
8334 types. Deprecates the silc_server_send_set_mode function.
8336 * Added SERVER_SIGNOFF notify type to indicate that server has
8337 quit. This means that all clients on the channel from that
8338 server will drop. This can be also used when netsplit happens.
8340 Deprecated REMOVE_ID packet type since it is not needed anymore
8343 Added silc_server_send_notify_server_signoff to send the
8344 SERVER_SIGNOFF notify type. Deprecates the function
8345 silc_server_send_remove_id.
8347 Added also silc_server_send_notify_signoff to send the
8348 SIGNOFF notify type.
8350 * Employed the PKCS #1. It is the mandatory way to do RSA in the
8351 SILC protocol from this day on. Changed the protocol
8352 specification as well.
8354 * Added silc_server_send_notify_topic_set to send TOPIC_SET
8355 notify type. It is used between routers to notify about
8356 topic changes on a channel.
8358 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
8361 * Partly updated the protocol specification to comply with the
8362 changes now made. It is still though a bit outdated.
8364 * The JOIN notify type now takes one extra argument <Channel ID>.
8365 The packet used to be destined to the channel but now the
8366 JOIN type may be sent as list thus it is impossible to
8367 destine it to any specific channel. By adding this argument
8368 it is again possible.
8370 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8372 * Added CREDITS file. The CHANGES and CREDITS file will appear
8373 in the distribution as well.
8375 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8377 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
8378 types in the server's silcd/packet_receive.c.
8380 * Implemented CMODE and CUMODE to work in router environment.
8382 * Fixed minor encoding and decoding buglet from the
8383 lib/silccore/silcmode.c.
8385 * Fixed buffer overflow from lib/silcclient/command.c in USERS
8388 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
8390 * Changed all SilcConfigServer* and silc_config_server* to
8391 SilcServerConfig* and silc_server_config*, respectively.
8394 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8396 * Associated the ID (client or server ID) to the Authentication
8397 Payload to avoid any possibility of forging. Updated the
8398 protocol specification and the code accordingly.
8400 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8402 * The RSA key length is now save to the RsaKey context in the
8403 key generation process in lib/silccrypt/rsa.c. The key length
8404 is now used to figure out the maximum size of the block allowed
8405 to be encrypted/signed.
8407 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
8408 is equivalent to the silc_mp_mp2bin but does not allocate any
8411 * Changed silc_mp_mp2bin API to take length argument. If it is
8412 non-zero then the buffer is allocated that large. If zero, then
8413 the size is approximated using silc_mp_sizeinbase, which however
8416 * Created Global RNG API which is global RNG that application can
8417 initialize. After initializing, any routine anywhere in the
8418 code (including library) can use RNG without allocating a new
8419 RNG object. This was done to allow this sort of use of the
8420 RNG in code that has no chance to allocate RNG object. All
8421 applications currently allocate this and many routines in the
8422 library use this. Affected file lib/silccrypt/silcrng.[ch].
8424 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
8425 it to use the Global RNG API.
8427 * Defined Authentication Payload into protocol specification that
8428 is used during SILC session to authenticate entities. It is
8429 used for example by client to authenticate itself to the server
8430 to obtain server operator privileges.
8432 Implemented this payload into the lib/silccore/silcauth.[ch].
8433 Implemented also routines for public key based authentication
8434 as the new protocol specification dictates.
8436 Moved definitions of different authentication methods from
8437 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
8439 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
8440 silc_pkcs_verify and silc_pkcs_sign_with_hash and
8441 silc_pkcs_verify_with_hash functions into the file
8442 lib/silccrypt/silcpkcs.[ch].
8444 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8446 * The client entry's userinfo pointer must be always valid.
8447 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
8448 will fail since it requires the userinfo. Now, the userinfo
8449 is allocated as "" if actual userinfo does not exist. Actually,
8450 it must exist and it is totally Ok to drop client connections
8451 that does not announce the userinfo. However, we will make
8452 this workaround for now.
8454 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
8455 to return the remote port by socket.
8457 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8459 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
8460 SILC_SERVER_PENDING_EXEC and added an new macro
8461 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
8462 data or when error occurs while processing the pending command.
8464 Added new argument `destructor' into silc_server_command_pending
8465 and to the SilcServerCommandPending object. This destructor is
8466 now called after calling the pending callback or if error occurs
8467 immediately. If error occurs the actual pending callback won't
8468 be called at all - only the destructor. The destructor may be
8469 NULL if destructor is not needed.
8471 All this applies for client library code as well. Similar
8472 changes were made there as well for the pending commands.
8474 In the client, the application must now allocate the
8475 SilcClientCommandContext with the silc_client_command_alloc
8478 * Added reference counter to the SilcServerCommandContext. Added
8479 function silc_server_command_alloc and silc_server_command_dup
8482 Same type of functions added to the client library for the same
8485 * Removed the cmd_ident from IDListData away since it is now
8486 global for all connections. It is the command identifier used
8487 in command sending and with pending commands. The affected file
8490 * Added reference counter to the SilcSocketConnection objecet to
8491 indicate the usage count of the object. The object won't be
8492 freed untill the reference counter hits zero. Currently only
8493 server uses this, and client ignores it. The client must be
8494 set to use this too later. The affected files are
8495 lib/silccore/silcsockconn.[ch]. Added also the function
8496 silc_socket_dup to increase the reference counter.
8498 This was mainly added because it is possible that the socket
8499 is removed underneath of pending command or other async
8500 operation. Now it won't be free'd and proper DISCONNECTING
8501 flags, etc. can be set to avoid sending data to connection that
8502 is not valid anymore.
8504 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
8505 the connection. After that it sets SILC_SET_DISCONNECTED.
8506 It is, however, possible that the socket data is not still freed.
8507 The silc_server_packet_process now checks that data is not
8508 read or written to connection that is DISCONNECTED. The socket
8509 get's freed when the reference counter hits zero.
8511 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8513 * Changed the client operation API: channel_message operation's
8514 `sender' is now the client entry of the sender, not the nickname
8515 and the `channel' is the channel entry, not the channel name.
8517 In the private_message operation the `sender' is now also the
8518 client entry of the sender not the nickname.
8520 Affected file is lib/silcclient/ops.h and all applications
8521 using the client operations.
8523 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8525 * Moved the calling of ops->connect() from connect_to_server_final
8526 into receive_new_id functin since that is the point when the
8527 client is actually allowed to send traffic to network. The
8528 affected file is lib/silcclient/client.c.
8530 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8532 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
8533 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
8534 (if needs broadcasting) instead of broadcasting the packets one
8535 by one which would make a burst in the network traffic.
8537 * Added `broadcast' argument to the functions in silcd/server.[ch]
8538 silc_server_create_new_channel[_with_id] to indicate whether
8539 to send New Channel packet to primary router.
8541 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8543 * Added new function into the silcd/server.[ch] files:
8544 silc_server_create_new_channel_with_id to create new channel with
8545 already existing Channel ID.
8547 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
8548 lib/silccore/silcpacket.h. This packet is used t send list of
8549 Set Mode payloads inside one packet. Server uses this to set
8550 the modes for the channels and clients on those channels, that it
8551 announced to the router when it connected to it. The protocol
8552 specification has been updated accordingly.
8554 * The silc_server_new_channel did not handle the packet coming
8555 from normal server as it normally does not send that. However,
8556 when it announces its channels it does send it. Implemented
8557 the support for that.
8559 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
8560 into the file lib/silccore/id.h.
8562 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8564 * Fixed memory leaks in the functions silc_idlist_del_client,
8565 silc_idlist_del_channel and silc_idlist_del_server in the file
8566 silcd/idlist.c. All of those leaked like a sieve.
8568 * Fixed some small memory leaks in the client's function
8569 silc_client_notify_by_server.
8571 * Added functions into silcd/server.c: silc_server_announce_clients,
8572 silc_server_announce_channels and silc_server_announce_server.
8573 These functions are used by normal and router server to announce
8574 to its primary router about clients, channels and servers (when
8575 router) that we own. This is done after we've connected to the
8578 These functions effectively implements the following packet types:
8579 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
8580 and SILC_PACKET_NEW_ID_LIST.
8582 * Added new functions into the silcd/packet_receive.[ch]:
8583 silc_server_new_id_list, silc_server_new_channel_list and
8584 silc_server_new_channel_user_list to handle the incoming
8585 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
8587 * Added support of changing Channel ID in the function
8588 silc_server_replace_id. If the server that announces a channel
8589 to the router already exists in the router (with same name but
8590 with different Channel ID), router is responsible to send
8591 Replace ID packet to the server and force the server to change
8592 the Channel ID to the one router has.
8594 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
8595 client that the Channel ID has been changed by the router. The
8596 normal server sends this to the client. Client must start using
8597 the new Channel ID as the channel's ID.
8599 Implemented handling of this new type into lib/silcclient/client.c
8600 into the function silc_client_notify_by_server.
8602 * Added new function silc_idlist_replace_channel_id into the files
8603 silcd/idlist.[ch] to replace the Channel ID.
8605 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8607 * Call silc_server_command_identify_check always when processing
8608 the IDENTIFY command in silcd/command.c
8610 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8612 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
8613 send keepalive packets. The packet can be sent by clients,
8614 servers and routers.
8616 Added function silc_socket_set_heartbeat into the file
8617 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
8618 If not set, the heartbeat is not performed. The actual
8619 heartbeat is implemented in the low level socket connection
8620 library. However, application is responsible of actually
8623 Added silc_server_send_heartbeat to send the actual heartbeat
8624 packet into silcd/packet_send.[ch]. Server now performs
8625 keepalive with all connections.
8627 * Added silc_task_get_first function into lib/silcutil/silctask.c
8628 to return the timeout task with shortest timeout. There was a bug
8629 in task unregistration that caused problems. TODO has been
8630 updated to include that task system must be rewritten.
8632 * The client library will now resolve the client information when
8633 receiving JOIN notify from server for client that we know but
8634 have incomplete information.
8636 * Rewrote parts of silc_server_remove_from_channels and
8637 silc_server_remove_from_one_channel as they did not remove the
8638 channel in some circumstances even though they should've.
8640 * Encryption problem encountered in server:
8642 The LEAVE command used to send the Channel Key packet to the
8643 router immediately after generating it. However, the code
8644 had earlier sent Remove Channel user packet but not immediately,
8645 ie. it was put to queue. The order of packets in the router
8646 was that Channel Key packet was first and Remove Channel User
8647 packet was second, even though they were encrypted in the
8648 reverse order. For this reason, MAC check failed. Now, this
8649 is fixed by not sending the Channel Key packet immediately but
8650 putting it to queue. However, this is more fundamental problem:
8651 packets that are in queue should actually not be encrypted
8652 because packets that are sent immediately gets encrypted
8653 actually with wrong IV (and thus MAC check fails). So, packets
8654 that are in queue should be encrypted when they are sent to
8655 the wire and not when they put to the queue.
8657 However, the problem is that the current system has not been
8658 designed to work that way. Instead, the packet is encrypted
8659 as soon as possible and left to the queue. The queue is then
8660 just purged into wire. There won't be any fixes for this
8661 any time soon. So, the current semantic for packet sending
8664 o If you send packet to remote host and do not force the send
8665 (the packet will be in queue) then all subsequent packets to the
8666 same remote host must also be put to the queue. Only after the
8667 queue has been purged is it safe again to force the packet
8670 o If you send all packets immediately then it safe to send
8671 any of subsequent packets through the queue, however, after
8672 the first packet is put to queue then any subsequent packets
8673 must also be put to the queue.
8675 Follow these rules and everything works fine.
8677 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8679 * Added new function silc_server_remove_clients_by_server to
8680 remove all client entries from ID list when the server connection
8681 is lost. In this case it is also important to invalidate all
8682 client entires as they hold the invalid server entry. This
8683 fixes fatal bug when server has lost connection and will reconnect
8686 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8688 * Made some sanity checks to silc_server_daemonise like to check
8689 whether the requested user and group actually exists.
8691 * Added sanity check to SKE's silc_ske_responder_finish to check
8692 that the public and private key actually is valid.
8694 * Invalidate the client's nickname when receiving Replace ID
8695 packet and the Client ID is being replaced. This means that the
8696 server will query the nickname if someone needs it (client)
8699 * Sort the ID Cache in client library when the ID Cache data
8700 has changed (needs sorting).
8702 * Do not allow for SILC client to create several connections to
8703 several servers. The client does not support windows right now
8704 and generating multiple connections causes weird behaviour.
8706 Irssi-silc client does support windows and can handle several
8707 connections without problems, see: www.irssi.org and SILC plugin.
8709 * Fixed some places where client was added to the IDList. The
8710 rule of thumb is following (in order to get everything right):
8711 If the client is directly connected local client then the
8712 `connection' argument must be set and `router' argument must be
8713 NULL to silc_idlist_add_client function. If the client is not
8714 directly connected client then the `router' argument must
8715 bet set and the `connection' argument must be NULL to the
8716 silc_idlist_add_client function.
8718 * The funtion silc_server_packet_send_local_channel actually did
8719 not check whether the client was locally connected or not. It
8720 does that now. Fixed a bug related to LEAVE command.
8722 * Fixed Remove Channel User payload parsing bug in server's
8723 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
8725 * The server's silc_server_save_channel_key now checks also the
8726 global ID list for the channel as it might not be in the local
8727 list. Fixed a bug related to LEAVE command.
8729 * Is this the end of the [<unknown>] buglet that has been lurking
8730 around for a long time? A little for loop fix in server's
8731 silc_server_command_whois_parse that is used by both IDENTIFY
8732 and WHOIS command. At least, this was a clear bug and a cause
8733 of one type of [<unknown>] buglet.
8735 * WHOIS and IDENTIFY commands call the function
8736 silc_server_command_[whois/identify]_check function even if
8737 we are not router server.
8739 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8741 * Added --with-gmp configuration option. If set the GMP
8742 is always compiled in the SILC source tree. If not set then
8743 it is checked whether the system has the GMP3 installed. If
8744 it has then the GMP won't be compiled (the system's headers
8745 and library is used), if it doesn't have it then the GMP is
8746 compiled in the SILC source tree.
8748 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8750 * Changed RSA private exponent generation to what PKCS #1
8751 suggests. We try to find the smallest possible d by doing
8752 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
8753 not security fix but optimization.
8755 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8757 * Added new config entry [Identity] to fork the server and run
8758 it as specific user and group. A patch from Bostik.
8760 * Imported Dotconf configuration library into lib/dotconf.
8761 This will be used to create the SILC configuration files later.
8762 It will appear in the distsribution after this commit.
8764 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8766 * A big code auditing weekend happening. Auditing code for
8767 obvious mistakes, bugs and errors. Also, removing any code
8770 Removed files for being obsolete:
8772 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
8773 inline in the file lib/silcutil/silcbuffer.h)
8775 o lib/silcutil/silcbufutil.c (the header has inline versions)
8777 Changed code to fix possible error conditions:
8779 o The buffer formatting routines now check that the destination
8780 buffer really has enough space to add the data. This applies for
8781 both buffer formatting and unformatting
8782 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
8783 unformatting was changed to accomodate following rules:
8784 XXX_*STRING_ALLOC will allocate space for the data into the pointer
8785 sent to the function while XXX_*STRING will not allocate or copy
8786 the data into the buffer. Instead it sets the pointer from the
8787 buffer into the pointer sent as argument (XXX_*STRING used to
8788 require that the pointer must be allocated already). This change
8789 makes this whole thing a bit more consistent and more optimized
8790 (note that the data returned in the unformatting with XXX_*STRING
8791 must not be freed now). The routines return now -1 on error.
8793 o Tried to find all code that use buffer_format and buffer_unformat
8794 and added return value checking to prevent formatting and
8795 especially unformatting errors and possible subsequent fatal
8798 o Changed ske->x and ske->KEY to mallocated pointers in
8799 lib/silcske/silcske.h. Fixed possible data and memory leak.
8801 o Added return value checking to all *_parse* functions. Fixed
8802 many memory leaks as well.
8804 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
8805 so that buffer overflows would not happen. All code now also
8806 checks the return value as it can fail.
8808 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8810 * Added reconnection support to server if the normal server looses
8811 its connection to the router (for example if router is rebooted).
8812 The server performs normal reconnection strategy implemented
8813 to the server. Affected file silcd/server.c.
8815 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8817 * Added new packet type SILC_PACKET_SET_MODE that is used to
8818 distribute the information about changed modes (for clients,
8819 channels and clients channel modes) to all routers in the
8820 network. Updated the protocol specification accordingly.
8822 Added functions into silcd/packet_send.c and
8823 silcd/packet_receive.c: silc_server_send_set_mode,
8824 silc_server_set_mode.
8826 Added new files silcmode.[ch] into lib/silccore that implements
8827 the encoding and decoding of Set Mode Payload. Added new type
8828 SilcSetModePayload. Moved the definitions of different modes
8829 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
8831 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8833 * Oops, a little mistake in server's connection authentication
8834 protocol. The protocol is not ended with FAILURE but with
8835 SUCCESS if the authentication is Ok. :) Affected file is
8838 * Implemented NICK_CHANGE notify handling in server in the file
8839 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
8840 the local clients on the channel. After the changing nickname
8841 in router environment snhould work and the [<unknown>] nickname
8842 should appear no more.
8844 The silc_server_replace_id function that receives the Replace ID
8845 payload now sends the NICK_CHANGE notify type also in the file
8846 silcd/packet_receive.c
8848 * Changed WHOIS and IDENTIFY command to support the maximum amount
8849 of arguments defined in protocol specs (3328 arguments). This
8850 fixed a bug that caused problems when there were more than three
8853 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8855 * Added extra parameter, command identifier, to the
8856 silc_client_send_command so that explicit command identifier
8859 Changed that ID list routines uses specific command identifier
8860 when sending WHOIS/IDENTIFY requests to the server so that they
8861 can be identified when the reply comes back.
8863 Affected files lib/silcclient/command.[ch],
8864 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
8866 * Added `sender' argument to silc_server_packet_send_to_channel
8867 to indicaet the sender who originally sent the packet to us
8868 that we are now re-sending. Ignored if NULL. Affected file
8869 silcd/packet_send.[ch].
8871 * Added some server statistics support in silcd/server_internal.h
8872 SilcServerStatistics structure and around the server code. Also
8873 send some nice statistics information when client is connecting
8876 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8878 * Fixed channel ID decoding in server's JOIN command reply in
8879 silcd/command_reply.c
8881 * Fixed braodcasting of replace ID payload to not to send it if
8882 we are standalone server in silcd/packet_receive.c.
8884 * Fixed all channel message sending routines to not to send
8885 packets to clients that has router set, since they are routed
8886 separately in the same function earlier. Affects file
8887 silcd/packet_send.c and all channel packet sending functions.
8889 * In USERS reply, res_argv[i] are not allocated, the table
8890 is allocated. Thus changed that free the table, not its
8893 * In server's whois_check and identify_check if the client is
8894 locally connected do not send any WHOIS commands - they are not
8897 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8899 * Fixed some minor bugs in client when sending WHOIS command. The
8900 arguments was in wrong order.
8902 * Removed statis function add_to_channel from server in
8903 silcd/command.c that was previously used with the joining but
8906 * Tested USERS command in router environment successfully with two
8907 routers, two servers and two clients.
8909 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8911 * Reorganized the USERS command and command reply in client library
8912 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
8913 When the command is given by user we register a pending command
8914 callback that will reprocess the command after the reply has been
8915 received from the server. When reprocessing the packet we then
8916 display the information. Thus, the USERS information is displayed
8917 now in the command callback instead of in the command reply
8918 callback. The processing of the command is same as previously
8919 when server has sent the command reply in the JOINing process.
8921 * Added to USERS command in silcd/command_reply.c to join the client,
8922 we didn't use to know about, to the channel after we've created
8923 a client entry for it. Also, for clienet we did know already still
8924 check whether it is on the channel or not and add it if not.
8926 * Removed silc_server_command_join_notify as the function and its
8929 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8931 * Changed the client's pending command handling to the same as the
8932 server's pending command handling. It is also now possible to
8933 execute command reply functions from other command reply
8934 function as the function callbacks for commands and command
8935 replies are one and same. The pending commands are not static
8936 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
8937 in client connection context. Thus, pending commands are server
8938 connection specific as it is convenient.
8940 Changed the function silc_client_command_pending and
8941 silc_client_command_pending_del and added new function
8942 silc_client_command_pending_check. Removed the
8943 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
8946 * Added cmd_ident, current command identifier, to the client
8947 connection context in lib/silcclient/client.h to keep track on
8948 command identifiers used in command sending. Client's command reply
8949 function handling now supports the mandatory command identifiers.
8951 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
8952 funtions in client to fully support pending command callbacks.
8954 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
8955 as one of the arguments to the application in the command reply
8958 * NOTE: The FORWARDED flag is depracated. It used to be depracated
8959 before first releasing SILC but came back. Now it is removed again
8960 and should come back nomore. The FORWARDED flag was used only
8961 by the JOINing procedure by forwarding the command packet to router.
8962 Now, the JOINing procedure has been changed to more generic (due
8963 to various router environment issues) and FORWARDED is not needed
8964 anymore for anything. The protocol specification is yet to be
8967 Now, removed silc_server_packet_forward from server and the flag
8968 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
8970 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8972 * Renamed NAMES command to USERS command. The NAMES was named that
8973 due to historical reasons. Now it is renamed. Also, rewrote
8974 parts of the USERS command. The nickname list is not sent anymore
8975 by the server. Only Client ID and mode lists are sent in the USERS
8976 command. Changed this also to the protocol specification.
8978 The client now resolves the names and stuff after it receives
8979 the USERS list from the server when joining to the channel.
8981 * WHOIS and IDENTIFY commands has been changed to support multiple
8982 Client ID's per command. One can now search for multiple users
8983 in the network by sending only one WHOIS or IDENTIFY command.
8984 Changed the code and the protocol specifications.
8986 * Removed silc_server_command_identify_parse and changed that IDENTIFY
8987 uses silc_server_command_whois_parse to parse the request. */
8989 * If normal server, do not parse the WHOIS and IDENTIFY requests
8990 before sending it to the router. Saves some time.
8992 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8994 * Fixed JOIN command on client library. Wrong number of arguments
8995 used to crash the client.
8997 * Added silc_server_channel_has_global function to check whether
8998 channel has global users or not.
9000 * Added silc_server_channel_has_local function to check whether channel
9001 has locally connected clients on the channel.
9003 * The silc_server_remove_from_one_channel now checks whether the
9004 channel has global users or not after given client was removed from
9005 the channel. It also checks whether the channel has local clients
9006 on the channel anymore. If it does not have then the channel entry
9007 is removed as it is not needed anymore.
9009 * The silc_server_notify now checks on JOIN notify whether the joining
9010 client is one of locally connected or global. If it is global then
9011 the channel has now global users on the channel and that is marked
9012 to the channel entry. Also, it now saves the global client to
9013 global list who is joining and JOINs it to the channel. This is
9014 for normal server, that is.
9016 Changed silc_server_send_notify_on_channel,
9017 silc_server_packet_relay_to_channel and
9018 silc_server_packet_send_to_channel check if we are normal server
9019 and client has router set (ie. global client) do not send the
9020 message to that client, as it is already routed to our router.
9022 * Implemented LEAVE notify type handling in silc_server_notify
9025 * Tested LEAVE command in router environment successfully. Tested
9026 with two routers, two servers and two clients.
9030 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
9032 * Implemented SIGNOFF notify type handling in silc_server_notify
9035 * silc_server_remove_id now removes the client entry from all channels
9036 it has joined and thusly sends SIGNOFF notify type.
9038 * Rewrote the NAMES list generation in server by removing two excess
9039 loops. The lists are created now inside one loop.
9041 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
9043 * silc_server_remove_channel_user checks now also global list
9044 for channel and client.
9046 * silc_server_new_channel_user checks now both local and global
9047 list for channel and client. Fixed a bug in client id decoding.
9048 Used to decode wrong buffer.
9050 * silc_server_channel_message checks now both local and global
9051 list for channel entry.
9053 * Tested channel joining (hence JOIN) in router environment
9054 successfully. Tested with two routers, two servers and two
9057 * Tested channel message sending in router environment successfully.
9059 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
9061 * Added silc_server_save_channel_key into server.[ch] to save the
9062 received channel key in Channel Key payload processing. It is
9063 also used in JOIN command reply handling.
9065 Equivalent function silc_client_save_channel_key added into
9066 client.[ch] into client library.
9068 * Changed JOIN command reply to send information whether the channel
9069 was created or not (is existing already) and the channel key
9070 payload. Changed protocol specs accordingly.
9072 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
9073 the request was sent by ID and not by nickname. Crashed on
9076 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9078 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
9079 now correctly save the received data.
9081 * silc_server_free_sock_user_data now notifies routers in the
9082 network about entities leaving the network.
9084 At the same time implemented functions silc_server_remove_id
9085 and silc_server_send_remove_id to receive and send REMOVE_ID
9086 packets. The packet is used to notify routers in the network
9087 about leaving entities. The ID removed will become invalid in
9090 * Added function silc_idlist_del_server into server. Removes and
9091 free's server entry from ID list.
9093 * silc_server_private_message function now checks, if we are router,
9094 that the destination ID really is valid ID, naturally.
9096 * In router when NEW_ID packet is received (for new client) the
9097 hash of the Client ID is saved in the ID Cache but the
9098 client->nickname is set to NULL, instead of putting the hash
9101 IDENTIFY command now also checks that client->nickname must be
9102 valid. If it is not if will request the data from the server who
9103 owns the client. Added new function
9104 silc_server_command_identify_check.
9106 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
9107 to set the command to already allocated Command Payload.
9109 * Tested private message sending in router environment with two
9110 routers, two servers and two clients. Fixed minor bugs and now
9113 * Fixed segfault from client's NAMES command. Used to crash if
9116 * Forwarded packets must not be routed even if it is not destined
9117 to the receiver. Changed server code comply with this.
9119 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9121 * Added `require_reverse_mapping' boolean value to ServerParams
9122 structure. If TRUE (not default) the server will require that
9123 the connecting host has fully qualified domain name.
9125 If the reverse mapping is not required and hostname could not be
9126 found the IP address is used as hostname.
9128 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9130 * Implemented version string checking to both client and server.
9131 The check is incomplete currently due to the abnormal version
9132 strings used in development version of SILC.
9134 * Changed all command functions in server to use the new
9137 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9139 * Changed char *data to unsigned char *data in ID Cache system to
9140 support binary data as ID Cache data. Changed code to support
9141 binary data in lib/silccore/idcache.c.
9143 * Renamed silc_server_packet_relay_command_reply to
9144 silc_server_command_reply as it is normal packet receiving
9145 function. Rewrote the function to accept command replys for
9146 servers and not only for clients.
9148 * Mark remote router always as registered server if we are connecting
9149 to it. Otherwise, commands sent by the router to us are ignored.
9151 * All ID List find routines now returns the ID Cache Entry pointer
9152 as well if requested.
9154 * WHOIS command works now in router environment, tested with two
9155 routers, two servers and two clients.
9157 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
9158 in router environment (as it is almost equivalent to WHOIS) but
9159 hasn't been tested thoroughly. Added new functions:
9161 silc_server_command_identify_parse
9162 silc_server_command_identify_send_reply
9163 silc_server_command_identify_from_client
9164 silc_server_command_identify_from_server
9166 * Disabled route cache adding because adding two different ID's with
9167 same IP replaces the old cache entry thus giving wrong route.
9168 The entry->router->connection is always the fastest route anyway
9169 so route cache may not be needed. Of course, new routes maybe
9170 established after receiving the ID when the entry->router->connection
9171 might not be anymore the most optimal.
9173 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9175 * Add route cache for received ID for fast routing.
9177 * Added silc_server_packet_route to route received packet on router
9178 that is not destined to us.
9180 * Renamed silc_server_get_route to silc_server_route_get.
9182 * Added id_string and id_string_len fields into SilcServer to
9183 include encoded ServerID for fast comparing without excess
9184 encoding of the ID's.
9186 * Cleaned up WHOIS command on server side. Added following static
9189 silc_server_command_whois_parse
9190 silc_server_command_whois_check
9191 silc_server_command_whois_send_reply
9192 silc_server_command_whois_from_client
9193 silc_server_command_whois_from_server
9195 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
9196 arguments in command replies. All command functions should be
9197 updated to use this macro.
9199 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9201 * Minor typo fixes on command reply handling on server.
9203 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9205 * Added silc_server_command_add_to_channel internal routine to add
9206 the client to the channel after router has created the channel and
9207 sent command reply to the server.
9209 * Added generic silc_server_send_command to send any command from
9212 * Use static buffer with ID rendering instead of duplicating data.
9214 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9216 * Fixed a channel user mode bug when joining to a channel server gave
9217 everybody channel founder rights, oops.
9219 * We mark ourselves as the router of the incoming server connection
9220 if we are router ourselves. This way we can check in some packet
9221 sending functions whether it is locally connected server. For
9222 incoming router connections we put NULL.
9224 * For router sending packets locally means now always sending the
9225 packet cell wide; to local clients and local servers. For normal
9226 server sending packet locally means sending it to only local
9229 * Fixed the JOIN command to really work in router environment. If the
9230 channel is created it is always created by the router. Router is
9231 also responsible of making the initial joining to the channel,
9232 sending JOIN notify to the sending server and distributing
9233 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
9234 does not exist server doesn't do anything else but forward the
9235 command to the router which performs everything.
9237 * Added silc_server_send_channel_key function to send the Channel Key
9240 * Added silc_server_create_channel_key to create new channel key. The
9241 channel key is now re-generated everytime someone joins or leaves
9242 a channel, as protocol dictates. Note: channel->key_len is the
9245 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9247 * Splitted server.[ch] finally. Created now packet_send.[ch] and
9248 packet_receive.[ch] to separate packet sending and receiving
9249 routines. The server.[ch] now includes everything else including
9250 actual packet processing (writing and reading data) and other
9253 Renamed silc_server_private_message_send_internal to
9254 silc_server_send_private_message. The routine is still though
9255 used only to relay private messages as server does not send
9256 private messages itself.
9258 Renamed silc_server_new_channel to silc_server_create_new_channel
9259 and added new function sicl_server_new_channel that handles the
9260 incoming New Channel packet. Added also new sending function
9261 silc_server_send_new_channel to send New Channel Payload.
9263 * Added new function silc_server_notify to process incoming notify
9264 packet to the server/router. Server may then relay the notify
9265 to clients if needed.
9267 * Added new function silc_server_new_channel_user to process incoming
9268 New Channel User packet. Router will redistribute the packet and
9269 send JOIN notify to its local clients and locally connected servers
9270 if needed. Normal server will send JOIN notify to its local client
9271 on same channel when received this packet. Added also corresponding
9272 sending function silc_server_send_new_channel_user to sent the
9275 * Added boolean route argument to send_notif_to_channel and
9276 packet_send_to_channel functions to attempt to route the packet
9277 if it is TRUE and send only locally if it is FALSE.
9279 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9281 * silc_server_replace_id now broadcasts the received replace ID
9282 packet if it is not broadcast packet already. The router must
9283 broadcast to inform other routers about changed ID.
9285 * Added backpointer to server's router into SilcServer context in
9286 silcd/server_internal.h.
9288 * Fixed silc_server_packet_broadcast to send correct broadcast
9291 * The channel key is now distributed to the local client as soon
9292 as it is received from the router (in router environment) so that
9293 no other packet may be sent for the channel until client has
9296 * silc_server_remove_channel_user now broadcasts the received
9297 Remove Channel User packet if it is not broadcast packet already.
9298 The router must broadcast to inform other routers about removed
9301 * Added users field into SilcPacketContext that is a reference count
9302 of the context. One can increase the reference count by calling
9303 silc_packet_context_dup which is now changed to just increase the
9304 reference count instead of duplicating the data. The reference
9305 count is decresed by calling silc_packet_context_free that will
9306 free the data after the reference count hits zero.
9308 For now on the packet context and everything allocated into it
9309 (including the raw packet from network) must be freed by calling
9310 the new silc_packet_context_free function. Added also new function
9311 silc_packet_context_alloc that must be used now to allocate the
9312 context. This also means that if a routine is asynchronous from
9313 silc_[client/server]_packet_parse_type the packet context must
9314 be duplicated by calling silc_packet_context_dup. Otherwise it
9315 gets free'd after silc_[client/server]_packet_parse_type returns.
9316 Also, one must remember that if packet is duplicated then its
9317 reference count must be decresed by calling the free function as
9318 many times as it was duplicated.
9320 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
9321 from both client and server.
9323 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9325 * Made joining to a channel working in router environment.
9327 * Cleaned up JOIN command on server side and create function
9328 silc_server_command_join_channel internal routine to make the
9331 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9333 * Changed silc_command_pending list to SilcDList. Also, added
9334 `ident' field to SilcServerCommandPending structure to identify
9335 the reply and to call correct callback.
9337 Added silc_server_command_pending_check function to replace the
9338 corresnponding macro. The silc_command_pending list is not
9341 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
9342 to set identifier to previously allocated Command Payload. It
9343 is used to set identifier for command when resending Command
9346 * Added silc_command_payload_encode_payload to encode Command
9347 Payload buffer from SilcCommandPayload structure.
9349 * Added silc_argument_payload_encode_payload to encode Argument
9350 payload buffer from SilcArgumentPayload structure.
9352 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9354 * Changed WHOIS command to support router connection on server side.
9355 The whois request is always sent to router unless the server is
9356 standalone server. After server has received the reply from the
9357 router will it send the reply to the client.
9359 * Added silc_server_packet_broadcast into silcd/server.[ch] to
9360 broadcast received broadcast packet. The function is used only
9361 by router. The broadcast packet is always sent to the router's
9364 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
9365 render given ID to printable string, for log files for example.
9367 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9369 * Made basic router to router connections working. At least they
9370 can now connect to each other but nothing really works the way
9371 they are supposed - yet.
9373 * Added new initiator token to RouterConnection configuration
9374 file in silcd/serverconfig.[ch]. It is used to tell whether we
9375 are the initiator to the remote router or whether we'll expect
9376 the other end to connect.
9378 * Moved registering of listener task to silc_server_init, hence
9379 the server starts listenning as soon as it is run, even if it
9380 does not have connections to other routers. Let's see how well
9383 * Changed default connection retry timeouts for more suitable in
9386 * Removed cipher and such arguments from silc_idlist_add_client
9387 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
9388 Added new function silc_idlist_add_data to add the keys and stuff
9391 * Added SilcIDListData structure and added it to SilcClientEntry
9392 and SilcServerEntry as their first field in the structure. This
9393 way we can explicitly cast the ID entries to the SilcIDListData
9394 structure and get common data for the entries. In past, we had
9395 to first check what type of connection it is and then cast it to
9396 correct ID entry type. Now, we can directly cast the opaque
9397 pointer to the SilcIDListData (no matter what ID entry it actually
9398 is) and get the data needed.
9400 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9402 * Wow, found a bug in scheduler. The scheduler uninitialized itself
9403 in some circumstances even if threre were timeout tasks, though not
9404 IO tasks, but tasks anyway. Now fixed.
9406 * Defined SilcServerConnection structure to hold connection specific
9407 stuff about directly connected servers and routers. The definition
9408 is currently in silcd/server_internal.h. I thought about having
9409 a bit more important role fro this struct but for now it is used
9410 only when connecting to other server (or router actually).
9412 * Added connecting retry support in server when connecting to
9413 router(s). The retry feature implement exponential backoff
9414 algorithm. Also, added SilcServerParams structure to hold default
9415 parameters for server. For now, it include these retry settings
9416 and are hard coded. After server is moded to be as Silc Server
9417 Library this structure will be more important.
9419 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9421 * Changed client librarys channel->clients table to SilcList and
9422 changed code accordingly.
9424 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9426 * Changed client's channel table to SilcList and changed code
9427 accordingly. Also changed SilcChannelClientEntry to include back-
9428 pointer to the channel so that client entry can use that structure
9429 as list as well and we have fast cross-reference to the channel.
9430 This change dramatically decreased the complexity of channel
9431 handling with client entry and vice versa (removed one extra
9432 loop when searching for channel entry from many functions).
9434 * Changed server->sim from table to SilcDList and changed code
9437 * NAMES command can now be used from user interface. It will show
9438 the user list on the channel, neatly.
9440 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
9441 Code now saves realname of the user if it becomes available.
9443 * Renamed configure.in to configure.in.pre and made ./prepare
9444 script to automatically add correct version string to
9445 configure.in which it creates from configure.in.pre.
9447 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9449 * NAMES command reply now shows users mode with the nickname when
9452 * Moved silc_client_ch[u]mode[_char] functions from
9453 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
9454 place sucks, they are utility functions and should be in some
9457 * Fixed some unsigned int's to unsigned short's. Patch by cras.
9459 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
9462 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9466 * Added TRQ (efficient deque and list library) into lib/trq. This is
9467 a very good list library that is currently used in the SILC. Defined
9468 SilcList API over the library because I didn't like the API very
9469 much. See lib/trq/silclist.h for the API and examples of how to
9470 use the API. Fixed various places in the code to use the new
9471 SilcList API. The SilcList is meant for lists that has a structure
9472 already defined as a list. It is not suitable to add just some
9473 context to the list (in TRQ, the context is the list actually).
9475 So, I defined SilcDList that can be used for the purpose where
9476 predefined list structure does not exit. This can be used as
9477 such list. Now some context just can be added to the SilcDList.
9478 Currently this list is not used in the SILC just yet, though there
9479 are a lot places where this can replace dynamically allocated
9480 tables and I will fix these places, later, to use SilcDList.
9481 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
9482 and use TRQ internally).
9484 Also fixed some annoying warning messages that the original TRQ
9485 code generated. Also minor changes to TRQ's Makefile.in.
9487 * Added support for querying by Client ID to both WHOIS and
9488 IDENTIFY commands into server, as required by the protocol.
9490 * Removed method function pointers from SilcBuffer structure. They
9491 weren't used to anything and just increased the context size for
9492 no good reason. This change also made silc_buffer_alloc and
9493 silc_buffer_free functions inline functions.
9495 * Disabled command flooding detection support until it's fixed so
9496 that it accepts commands in but does not execute them more than once
9499 * Added silc_net_localhost(), to return local hostname, into
9500 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
9501 that must be initialized before calling silc_client_init.
9503 * Added new function: silc_server_send_notify_on_channels to send
9504 notify messages to all channels client has joined. It is assured
9505 that the message is sent only once per client.
9507 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
9508 lib/silcutil/silcutil.[ch] as silc_format function. The new
9509 function is generic and is used by server as well, not only by
9510 the logging routines.
9512 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
9513 the provided version string was not acceptable. Added new function:
9514 silc_ske_check_version into lib/silcske/silcske.h. The function
9515 must be implemented by the application (client or server) and it
9516 does not reside in the SKE library. The function checks the version
9517 string remote end sent.
9519 * Added back pointers (to opaque context and to SilcSocketConnection)
9520 into SilcPacketContext structure into lib/silccore/silcpacket.h.
9522 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
9523 duplicate packet context structure.
9525 * Changed `notify' client operation to send same arguments as client
9526 receives from server except for ID's. ID's are mapped to correct
9527 ID entry and that is returned. Also, if channel entry is not sent
9528 by server but the notify is for channel the channel entry is sent
9529 to application (otherwise application doesn't know that it is for
9530 channel (library gets it from packet's Destination ID)).
9532 * Added silc_client_remove_from_channels into client library to
9533 remove a client from all channels it has joined to. Used when
9534 received SIGNOFF notify from server. Added also new function
9535 silc_client_replace_from_channels to replace old ID entry with
9536 new ID entry on all channels. Used when received NICK_CHANGE
9539 * Fixed ID Cache list handling in silc_idlist_get_client in
9540 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
9541 to get (or query) client by ID.
9543 * Updated TODO list.
9545 * Added connection authentication status message defined by the
9546 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
9547 support for these into the code in client and server side.
9549 * Added generic function silc_client_send_command to send any command
9550 with variable argument list. Application should use this function
9551 to send commands if the command functions provided by the library
9552 does not suite for the application's user interface needs.
9554 * Added new `failure' client operation. Application is notified about
9555 received failure packet if client is executing a protocol. In this
9556 case the protocol's execution has failed.
9558 * Added SKE's end notify to send the SKE_SUCCESS notify message that
9559 is required by the protocol.
9561 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
9562 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
9565 * Added status flag to SilcSKE object to indicate realtime status
9566 of the SKE protocol.
9568 * Application receives now exactly same command reply arguments as
9569 the library receives from server. However, if ID is received the
9570 corresponding ID entry is returned to the application (eg. Client
9571 ID is mapped to correct SilcClientEntry entry and that is returned).
9572 Changed command_reply client operation due to this change.
9574 * Changed all ID's in commands and in command replys as ID Payloads.
9575 Change affected both client and server side codes.
9577 All ID's sent in SILC network (with execption of ID's in SILC
9578 Packet header) are sent in ID Payload to support variable length
9581 * Server now notifies nick changes and notifies all clients on
9582 the channels about the new nickname (about the new Client ID,
9585 * Implemented CMODE command to change channel modes. Supports all
9586 channel modes defined by the protocol specs except ban and invite
9587 lists. (Also, private channel key mode is supported but support for
9588 setting private channel key in client is missing, thus, this mode
9589 has no effect on client side (except that server requires that the
9590 client uses private channel key and normal channel traffic does not
9593 Also, invite mode works per se, but INVITE command does not work
9594 yet correctly, so you can set channel as invite only channel but
9595 inviting clients to the channel does not work (it is yet to be
9596 thought what's the best way to do it).
9598 * Added new command SILC_COMMAND_CUMODE to change user mode on the
9599 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
9600 Implemented CUMODE command to change user's mode on the channel.
9601 Supports all modes defined by the protocol specs.
9603 * Added NAMES command reply to return users modes on the channel.
9605 * Removed unnecessary and slow ciphers from lib/silccrypt.
9607 * Set SO_KEEPALIVE option to connection sockets by default.
9609 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
9611 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
9612 redefined the Notify Payload into protocol specs.
9614 * Added silc_id_payload_parse_id to get ID directly from raw
9617 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9619 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
9620 accept searching by Client ID as well.
9622 * Added support for LEAVE and SIGNOFF notify types in client library.
9624 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
9625 to parse ID Payload from raw data.
9627 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9629 * Added flags parameter into silc_ske_assemble_security_properties
9630 function in lib/silcske/silcske.[ch].
9632 * Changed notify client operation to fit better for notify messages
9633 sent by server. The notify payload received from server is now
9634 passed to the application (after parsing it to SilcNotifyPayload).
9635 It is application's responsibility to retrieve the arguments
9636 from the payload and show the message the way it wants. The message
9637 sent by server is implementation specific.
9639 * Changed public keys to comply with the protocol specification.
9640 Old public keys are not supported anymore and are not compatible.
9642 * Removed nickname from Channel Payload as the latest draft removed
9643 it. The client must resolve the nickname from the NAMES command
9644 reply received when it joined the channel.
9646 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
9648 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9650 * Fixed some errors in protocol specification drafts.
9652 * Created lib/silccore/silcnotify.c to implement Notify Payload
9653 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
9654 generic payloads described by protocol specifications. The file
9655 includes implementations for ID Payload and Argument Payload.
9657 * Changed Command Payload implementation to use the new Argument
9658 Payload. Changed command_xxxx_payload to command_payload_xxxx
9659 to comply with SILC coding conventions.
9661 * Added suppport for Argument Payload handling in Notify Payload
9662 implementation as protocol requires it. Added the new support
9663 into server and client lib as well.
9665 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9667 * Added support for multiple nicknames on same channel. [n] is
9668 added locally to the nickname if there are more than one same
9669 nicknames on the channel.
9671 * Server now sends all nicknames that matched WHOIS request.
9672 Client also shows the list received from server.
9674 * Added TOPIC command to client side. User can now set and show
9675 current topic on channel.
9677 * Added MOTD command to client and server. Also, server sends the
9678 motd when client connects to the server.
9680 * Changed version strings to comply ISO 8601.
9682 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9684 * Fixed protocol error handling in client library. It should now
9685 cope even if the SKE fails for some reason.
9687 * Made new protocol specification drafts for submitting to IETF.
9689 * Implemented TOPIC command to server in silcd/command.c.
9691 * Added two new notify types into lib/silccore/silcnotify.h:
9692 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
9693 notify nickname change and topic setting/change on a channel.
9695 * API change of command_reply operation in client library. The
9696 application gets now the status type received from server as well.
9698 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9700 * Removed the function just added to lib/silcutil/silcschedule.[ch].
9702 * Cras fixed and optimized the packet handling even further and
9703 it should work now. Minor change to the prototype of function
9704 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
9706 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9708 * Added new function into lib/silcutil/silcschedule.[ch]:
9709 silc_schedule_with_fd to select() a specified fd. The function
9710 returns after timeout expires or data arrives or goes. The
9711 function is used by packet routines to wait that all data is
9712 received from network.
9714 * Fixed data reading from network in lib/silccore/silcpacket.c.
9715 The code now assures that all data is read from the fd and then
9716 continues packet processing. This was a bug fix since the code
9717 used to drop some data in some circumstances.
9719 * Added new function into lib/silcclient/client.[ch]:
9720 silc_client_start_key_exchange to start key exchange after
9721 connection has been established to server. The code internally
9722 now uses this funtion but its main purpose was to provide it
9723 for applications that perform their own connecting. After
9724 application has created a connection it merely calls this
9725 function to start the key exchange between client and server.
9726 The library takes care of everything else after that.
9728 Updated also lib/silcclient/README to explain the usage of
9731 * Do not send to application information that connection has
9732 been established. Application gets notified it by connect
9735 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9737 * Applied cras's patch to add silc_schedule_one function. The
9738 function runs scheduler once and returns.
9740 * Fixed the scheduler after cras messed it up. The timeout
9741 handling works now as it's supposed to work.
9743 * Added into lib/silccore/ silcnotify.h to include notify
9744 message types support. Changed silc_server_send_notify*
9745 functions, in server.[ch], to support those new notify types.
9746 Added the support for the notify types into client library,
9747 as well. Added new notify client operation into ops.h in
9750 * Changed silc_server_packet_send_to_channel to send normal
9751 packets instead of just channel message packets. The function
9752 is now used to send the notify packets to channels. It is not
9753 used to send channel message packets anymore, as server never
9756 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
9757 va_arg()s as it seems to require it nowadays. I guess, if SILC
9758 is compiled with older va_arg() the new code should work anyway.
9760 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9762 * Splitted core library. Core library (lib/silccore) includes
9763 now only SILC protocol specific core (and common) components.
9764 Created new utility library (lib/silcutil) that includes more
9765 generic purpose stuff. The stuff for util library was taken
9766 from the old core library. This was minor and easy split.
9768 * Created SILC Client Library (lib/silcclient) that includes
9769 implementation of the SILC client without user interface. This
9770 was major move from silc/ directory. The code has been changed
9771 so that it is transparent towards the user interface. The
9772 silc/ directory includes now the same user interface as before
9773 and it uses the new client library. Read lib/silcclient/README.
9774 Basicly, the client library performs everything else related
9775 to SILC except user interface handling. Also, configuration
9776 files are considered to be part of user interface and library
9777 does not handle them.
9779 This change also changed a lot of structures, function naming etc.
9780 Most important change was that SilcClientWindow object was
9781 renamed to SilcClientConnection in the client library. Created
9782 also new file lib/silcclient/ops.h. Also added new files
9783 silc/local_command.[ch] and silc/client_ops.[ch].
9785 All these changes were made to make it easier for user interface
9786 designers to create what ever user interface for the SILC client
9789 It is also expected that the server will be moved to lib
9790 directory as well and SILC Server Library will be created;
9791 sometimes in the future.
9793 * Removed Local commands from lib/silccore/silccommand.h as
9794 they are application specific and new client library does not
9795 handle any of those anymore.
9797 * Several functions moved to lib/silcutil/silcutilc.[ch] from
9798 old client implementation in silc/.
9800 * Added support for callback functions in SILC_LOG_* macros.
9801 Application can now set its own callbacks that will be called
9802 instead of using the default functions that will always print
9803 the debug messages to stderr (or stdout). Also, debugging can
9804 now be disabled by setting silc_debug to FALSE and re-enabled by
9805 setting it to TRUE. Note, that logging will still work even
9806 if debugging is disabled.
9808 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
9809 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
9810 silc_log_reset_debug_callbacks.
9812 * To enable debugging in silc client one must give now -d
9813 option on command line.
9815 * Changed silc_schedule_init to automatically allocate task queues
9816 if they are not allocated before calling it.
9818 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9820 * Added GMP 3.1 into math library.
9822 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9824 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
9825 a channel in SILC network. The packet is used by servers and
9826 routers to notify other routers that user has left a channel.
9827 This little feature was missing until now. Added the feature
9828 to protocol specification as well.
9830 Added functions: silc_server_send_remove_channel_user and
9831 silc_server_remove_channel_user into server.[ch].
9833 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
9834 lib/silccore/silcpacket.h. However, they are not implemented
9837 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9839 * Fixed joining to a channel and sending channel messages
9840 between server and router. The channel message sending should
9841 now work inside a cell.
9843 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9845 * Fixed the private message sending between server and router.
9846 The private message sending should now work inside a cell.
9848 * Added silc_server_replace_id into server.[ch] to replace
9849 existing ID in the SILC network.
9851 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
9852 and silc_idlist_replace_server_id into idlist.[ch] in server.
9854 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9856 * Fixed the server to server connections. Server can again now
9857 connect to router. Router to router connections probably does
9860 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9862 * Added dynamic protocol registering support. Now protocols can
9863 registered and unregistered on the fly. Patch by cras.
9865 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9867 * Added lib/contrib directory to hold routines that some platforms
9868 don't have but are needed by SILC.
9870 * Added getopt.c, getopt1.c and getopt.h from GNU C library
9871 into lin/contrib to provide getopt() and getopt_long() for
9872 those who don't have it.
9874 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9876 * Added AWAY command to client. When away message is set and
9877 client receives a private message packet the client automatically
9878 replies to the sender with the away message.
9880 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
9881 bug seemed to be the cause of recent problems when compiling
9884 * Added version detection support to SKE protocol specification
9885 and added the new changes to the SKE implementation as well.
9886 There were other minor changes in the SKE protocol as well.
9888 Many changes in lib/silcske/silcske.[ch] and in
9889 lib/silcske/payload.[ch].
9891 * Added ^U functionality, clear input line. Patch from cras.
9893 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9895 * Mainly small bugfixes on core library. Fixed some debugging
9896 logging and buffer overflow in silclog.c.
9898 * Updated config.sub and config.guess on the distribution tree.
9900 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9902 * Added command lagging support in server. Client may execute
9903 commands now only once in two seconds.
9905 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9907 * Optimized packet reception. MAC computation and checking is now
9908 also more optimized. A lot previously duplicated code is now
9909 used as generic by both client and server.
9911 * Fixed key pair generation in clientutil.c
9913 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9915 * Added into lib/silccore/silcbufutil.[ch] new function;
9916 silc_buffer_realloc.
9918 * Moved generic packet sending/encryption functions to
9919 lib/silccore/silcpacket.[ch] from client and server. Some
9920 rewriting of the functions.
9922 * Moved all generic packet reception/decryption functions to
9923 lib/silccore/silcpacket.[ch] from client and server. The
9924 packet processing is now much cleaner in both client and server.
9925 These were major changes in both client and server.
9927 * Created many common functions in server to do packet sending.
9928 Previously code were duplicated a lot, this has been removed
9931 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9933 * Rewrote major parts of the ID cache system. Don't know
9934 whether it is better now or not but at least the API is more
9937 * Major rewrite on ID cache stuff on client because of the ID
9938 cache API changes. Added idlist.c to client.
9940 * Also major rewrite on ID cache stuff on server as well.
9941 Major rewrite of idlist.[ch]. SilcXXXList's are now named
9942 SilcXXXEntry's. We won't keep anymore idlist specific pointers
9943 in hand, instead they are all put into the ID cache system now.
9944 All server_idlist_* routines uses ID cache now instead of
9945 traversing its own lists (those lists does not exist anymore).
9946 SilcIDList though still exists. Also, SilcXXXEntry's are
9949 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9951 * Finally made the SKE implementation compliant to the protocol
9952 specification. All mp integers are now binary encoded as
9953 opposed being HEX encoded.
9955 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
9958 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
9959 functions: silc_[encode/decode]_pem. Also added function
9960 silc_encode_pem_file to PEM encode with newlines ('\n') for
9963 * SILC public keys are now encoded either PEM or binary. Same
9964 option is for private keys as well. By default private keys
9965 are binary encoded and public keys PEM encoded. Silly HEX
9966 encoding were removed.
9968 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
9969 function to create fingerprints.
9971 * Fixed a bug in SHA1; does not change the original data anymore.
9973 * Partly implemented INFO command on client and server side.
9974 Fixed CLEAR command. Changes to SERVER command; show current
9975 server(s) when giving command without arguments. Added
9976 VERSION command to client.
9978 * Added check to server that unregistered connections cannot
9979 execute commands (unless it is specificly allowed).
9981 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9983 * Fixed screen refresh.
9985 * Fixed channel joining bug from client. On some circumstances
9986 client tried to join to a channel it had already joined.
9988 * Added public key verification process into client's protocol.c.
9989 The client now verifies the public key from user and saves
9990 it into ~./silc/serverkeys/ directory.
9992 Added into: clientutil.[ch]: silc_client_verify_server_key.
9994 * Changed SKE protocol's silc_ske_initiator_finish function
9995 to accept callback function that verifies the received public
9996 key. Removed old silc_ske_verify_public_key function.
9998 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
10000 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
10001 silc_pkcs_private_key[_data]_set.
10003 * Made the password and public authentication more cleaner in
10004 server's protocol.c.
10006 * Removed historic and obsolete protocol `channel_auth' from
10007 both client and server.
10009 * Removed wrong way of sending command status messages from
10010 server to client in server's command.c. The old way violated
10011 protocol specification.
10013 Changes to silccore/silccommand.[ch]: removed
10014 silc_command_encode_status_payload -> not needed anymore,
10015 changed silc_command_encode_payload_va to accept extra
10016 argument on variable argument list. The argument type must
10017 now be provided to the function. Also, added new function:
10018 silc_command_encode_reply_payload_va which is same as
10019 normal command_encode_payload_va except command status type
10020 is provided as extra argument.
10022 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
10024 * Added ~./silc directory handling. The directory includes the
10025 public and private keys for the client.
10027 Added silc_client_check_silc_dir, silc_client_create_identifier
10028 and silc_client_load_keys.
10030 * Implemented SILC protocol compliant public key. Added public
10031 and private key saving to and loading from files.
10033 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
10034 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
10035 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
10036 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
10037 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
10039 Implemented: silc_pkcs_save_[public/private]_key[_data] and
10040 silc_pkcs_load_[public/private]_key.
10042 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
10044 * Added silc_server_get_route (route.[ch]) to get connection
10045 data for the fastest route for given ID.
10047 * Implemented INVITE command on client and server. The command
10048 were re-defined in the SILC Protocol Specification and the
10049 implementation now complies with the specification.
10051 * Implemented PING command on client and server.
10053 * Implemented NAMES command on client and server. The server side
10054 supports currently only normal server not router server yet.
10055 Some changes to NAMES definition in SILC protocol specification.
10057 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
10059 * Implemented LEAVE command on client and server.
10061 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
10062 again. This change was made to the protocol as well. Server
10063 should not violate the protocol specification anymore.
10065 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
10067 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
10068 was tested. SOCKS4 was not but should work anyway.
