3 * Enable all local server connections before updating client
4 caches when we've become backup router. Otherwise, signoff
5 packets may not reach the clients. Affected files are
6 silcd/server.c and silcd/server_util.[ch].
8 * Fixed a bug in version string parsing which could crash
9 the program with specially formatted version string.
10 Bug reported and patch provided by Ville Räsänen. Affected
11 file lib/silcutil/silcutil.c.
13 * Handle the disconnection immediately when DISCONNECT
14 packet is received in server. Affected file silcd/server.c.
16 * Primary router now waits a short time (10 seconds) for
17 backup router connection before accepting any other
18 connection (except local). Affected file silcd/server.c,
21 * Fixed a crash in client libary in NICK_CHANGE notify when
22 NICK_CHANGE arrived for client entry we are resolving
23 currently. Affected file lib/silcclient/client_notify.c.
25 * Call the sconn->callback completion even if error had
26 occurred. Start reconnecting always if connection to
27 primary router fails during backup router protocol.
28 Affected files silcd/server.c and server_backup.c.
30 Mon Jun 24 17:47:52 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
32 * Added functions silc_server_send_opers and
33 silc_server_send_opers_notify to send packets stricly
34 to operators. Added macro SILC_SERVER_SEND_OPERS macro
35 to send variable argument notify to operators.
36 Affected files silcd/packet_send.[ch] and silcd/server.h.
38 * Removed UMODE rights checking with UMODE_CHANGE notify.
39 Affected file silcd/packet_receive.c.
41 * Server/router operator now receives notify when network
42 switches to backup router and when it resumes the use of
43 primary router. Affected file silcd/server.c and
44 silcd/server_backup.c.
46 * Fixed the updating of client information after backup
47 resuming protocol is over; update all except local clients
48 to the new primary router. The affected file is
51 * Added support for closing active connections in rehash
52 that were unconfigured by the user. Supports currently
53 closing server and router connections. Affected file
56 * Rewrote some SILC_LOG_DEBUG's in silcd/server_backup.c.
58 Sun Jun 23 17:32:31 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
60 * Don't do SILC_STRING_LANGUAGE encoding if the outbuffer
61 is NULL since seems that on some platforms NULL is allowed
62 and on some it's not. Fallback encoding is used instead.
63 Affected file lib/silcutil/silcstrutil.c.
65 * Fixed statistics updating for incoming server connection
66 which could cause problems when re-connecting. Affected
69 * Preliminary backup router support for standalone router
70 added. Affected files in silcd/.

73 and after backup protocol. Affected file is
74 silcd/server_backup.c.
76 * Added support for reconnecting to remote server connection
77 even if the protocol fails, and if the configuration wants
78 us to keep trying to connect anyway.
80 Server connection is not allowed to backup router if
81 backup router does not have connection to primary router yet.
83 Affected file is silcd/server.c.

87 * Added silc_client_udpate_server function to update changed
88 server info. Affected file lib/silcclient/idlist.[ch].
90 * Added check for server entries that are being resolved when
91 notify is received. If being resolved, handle the received
92 notify only after it's resolved so that all notifys are
93 handled in same order as received from the server.
95 Added similar resolver check to channel entries. Every
96 notify that cause resolving of any information that affects
97 channel entry marks the channel entry in waiting state.
98 After whatever resolving is over the waiters are signalled
99 and only then the notifys are handled in the same order
100 as delivered from the server.
102 Affected files are lib/silcclient/idlist.[ch], and
105 * Fixed KILLED notify handling in normal server. Affected
106 file silcd/packet_receive.c.
108 * Added SILC_IDLIST_STATUS_LOCAL which indicates that entry
109 is locally connected, or was locally connected (but may

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

156 * Added SILC_PRIMARY_ROUTE and SILC_BROADXAST macros to
157 silcd/server_internal.h. SILC_PRIMARY_ROUTE Returns pointer
158 to the primary router connection, the other one returns
159 TRUE if packet must be broadcasted to network.
161 * All notifys that are destined to primary router (to network)
162 are now automatically sent to backup routers even if the
163 router is standalone (and has backup router). Affected files
166 * Added --without-irssi and --without-silcd configuration
167 options for disabling the compilation of these applications.
168 Affected file configure.in.pre and prepare.

194 command reply from router, on normal server. Otherwise
195 joinig +a channels from normal server is not possible.
196 Affected file silcd/command.c.
198 * Fixed a bug in TOPIC_SET notify handling. The notifier
199 may be other than client too, like server or channel.
200 It expected it to always be only client and ignored the
201 notify. Affected file silcd/packet_recieve.c.
203 * Removed some (unnecessary) debug printing from
204 lib/silccore/silcid.c and lib/silccore/silcargument.c.
206 * Do not force CMODE_CHANGE when server is announcing new
209 Router announces stuff only after server reannounces channel
210 after CHANNEL_CHANGE notify.
212 These fixes optimizes the announcing procedure, and perhaps
213 fixes some problems too. Affected file silcd/packet_receive.c.
215 * Fixed SERVER_SIGNOFF sending to local clients. It was
216 totally broken and sent the notify to all local clients,
217 instead of only to those that was on same channel as the
218 signing off clients. Affected file silcd/server_util.c.
220 * Added -D option to server. It can be used to give debug
221 level. The levels are from 0 - 99, and are predefined for
222 smooth server debugging. (see silcd.c for the predefined
223 levels). Affected file silcd/server.c.
225 Wed Jun 19 16:01:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

235 channel. Affected file silcd/command.c.
237 * Better checking for founder mode setting when CUMODE_CHANGE
238 notify is received. Affected file silcd/packet_receive.c.

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

877 * The LIST command reply in client libary now adds new channel
878 entry if the returned channel doesn't exist yet in cache,
879 and returns the channel entry to the application in the
880 command_reply client operation. Affected file is
881 lib/silcclient/command_reply.c.
883 * Changed the channel message payload's MAC generation to
884 include the IV in the MAC as well. This way all relevant
885 parts of the channel message payload are authenticated also
886 with the channel message MAC (and not only by packet MAC).
887 Causes incompatibility with 1.0 protocol. Protocol TODO #7.
888 Affected file is lib/silccore/silcchannel.c.
890 * Fixed the SKE to save the remote version, since the
891 silc_ske_parse_version mistakenly checked wrong version,
892 after it replaced the start payload. Affected files are
893 lib/silcske/silcske.[ch].
895 Fri Apr 5 16:03:03 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

939 The killer's client entry is now returned to application in
940 the `notify' client operation.
942 * Fixed the Max Argument fields that had too large value set
943 in the protocol specs. Protocol TODO #14.
945 * Added the LEAVE command reply to return the ID of parted
946 channel. Updated protocol specs and implemented it to the
947 client and server. Protocol TODO #15. Affected files are

1011 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
1013 * Some client implementations quit network by doing first LEAVE
1014 and then immediately SIGNOFF (like Bombyx). We now do check
1015 after a short time after LEAVE notify and check whether the
1016 client is still valid after LEAVE, and if not we remove it from
1017 cache. Affected file is lib/silcclient/client_notify.c.
1019 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>

1045 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
1047 * Changed the silc_get_username and silc_get_real_name to
1048 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
1050 * Fixed the Irssi SILC Client to use the silc_get_username and
1051 silc_get_real_name insted of glib routines since the glib
1052 routines only corrupt stack. Fixes the Irssi SILC to work in
1053 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
1055 * Fixed the Irssi to not use g_get_home_dir since it crashes

1066 Affected files lib/silcsftp/sftp_fs_memory.c,
1067 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
1069 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1071 * And yet again reverted back the config thing since Johnny
1072 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
1075 * Fixed memory leaks from config object. Affected files are
1076 silcd/serverconfig.[ch].
1078 * Added support for adding new connections to the server in rehash.
1079 After rehash they take effect.
1081 Added support for changing the maximum allowed connections in
1082 rehash. The number can grow but going smaller is not supported.
1084 Added function silc_server_num_sockets_by_remote to the
1085 silcd/server_util.[ch].
1087 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
1089 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1091 * Added preliminary checking during config parsing for a valid
1092 public/private key and removed further checks in the code.
1093 Affected files are silcd/serverconfig.[ch], server.c.
1095 * Moved functions silc_server_drop() and silc_server_daemonise()
1096 from server.c to silcd.c since they are stricly related to
1097 the application activity.
1099 * Reverted a small part of the automatic ref/unref since
1100 it caused a double unref in some situations. Affected
1101 files are silcd/silcd.[ch], server.c, serverconfig.c.
1103 * Added some .cvsignore files in the lib directory.
1105 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1107 * Fixed silc_net_gethostbyaddr to correctly resolve by
1108 address. Affected file lib/silcutil/silcnet.c.
1110 * Fixed the notify relaying to client. The HMAC to be used
1111 with relayed packets ws wrong and caused decryption failure
1112 at the client end. Affected file is silcd/packet_receive.c.
1114 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1116 * Created new branch silc_protocol_1_0_branch.
1118 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
1120 * Changed the silc_server_config_* routines to be SilcServer
1121 independent. They are now officially application specific code
1122 and not part of generic server implementation. Affected files
1123 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
1125 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1127 * Added automatic referencing of config context in the
1128 silc_server_config_alloc, and automatic unreferencing in the
1129 silc_server_config_destroy. Affected files are
1130 silcd/serverconfig.[ch], silcd/silcd.c.
1132 * Fixed the silc_log_quick handling in the logging routines.
1133 It didn't log quickly when it was TRUE. Affected file is
1134 lib/silcutil/silclog.c. Also the flush delay was set even
1135 if it was 0 in config file. Affected file is
1136 silcd/serverconfig.c.
1138 * Added support for changing key pair of the server in rehash.
1139 Affected file silcd/server.c.
1141 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1143 * Fixed the TOPIC_SET notify to not cras. It changed the topic
1144 too early, before getting the channel entry. Affected file
1145 is silcd/packet_receive.c.
1147 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1149 * Added functions silc_server_config_[ref/unref], these are used
1150 to prevent that the config object is destroyed.
1152 No longer directly affect global variables silc_log_quick and
1153 silc_log_delay, they are first cached inside the config object
1154 and then applied with silc_server_config_setlogfiles().
1156 silc_server_config_set_defaults() is now internal to
1157 serverconfig.c, there are no reasons to show this internal stuff
1160 Affected files are silcd/serverconfig.[ch].
1162 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
1163 fprintf's to stderr, since some code may be executed again after
1164 the server went into the background. Affected files are
1167 * Added rehash support. Added function silc_server_rehash() that
1168 will perform all the basic tasks of the rehashing procedure.
1170 * Added command line option `-x, --hexdump'. This will enable the
1171 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
1172 The option `--hexdump' implies `--debug'.
1174 * Fixed a bad bug in the logging APIs (silcutil library) where
1175 the application would crash after calling silc_log_reset_all().
1177 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1179 * Fixed the KICKED notify handling in client library to
1180 correctly remove the channel and all entries from the
1181 channel when I was kicked. This bug crashed the client.
1183 Fixed yet another but in KICKED notify handling to remove
1184 the kicked client correctly from the channel.
1186 Affected file is lib/silcclient/client_notify.c.
1188 * Fixed a minor bug in looking up correct client entry
1189 in KICKED notify in server. Affected file is
1190 silcd/packet_receive.c.
1192 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
1193 sources correctly to distribution. Fixes --with-gmp option.
1195 * Removed the manual rehashing from ID Cache, and changed it
1196 to use the SILC Hash Table's auto rehash feature. Affected
1197 file is lib/silccore/silcidcache.c.
1199 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1201 * Fixed a bug in the silc_client_nickname_format function that
1202 handles the multiple same nickname formatting. Two clients
1203 with same nickname caused problems after the first one left
1204 and rejoined. It didn't format the nickname correctly.
1205 Affected file is lib/silcclient/idlist.c.
1207 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1209 * Don't change the topic if olod topic is same as new one.
1210 Affected file is silcd/packet_receive.c.
1212 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1214 * Added cross-reference support to the SILC Documentation
1215 generator. All types across all HTML files are now cross-
1216 referenced. Affected files util/robodoc/generator.c and
1217 scripts/silcdoc/silcdoc.
1219 * Added file lib/silcutil/silctypes.h to include all the
1220 arithmetic type definitions and some macros. Removed
1221 includes/bitmove.h and moved macros to silctypes.h.
1223 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1225 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
1227 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1229 * Added `type' argument to silc_id_payload_parse_id function which
1230 now returns the type of the ID to the sent pointer. Affected
1231 file is lib/silccore/silcid.[ch].
1233 * Added check for CMODE_CHANGE notify type that mode change is
1234 allowed by the sender. Affected file silcd/packet_receive.c.
1236 * Added check for CUMODE_CHANGE notify type that mode change is
1237 allowed by the sender. Affected file silcd/packet_receive.c.
1238 Added the ID type as CUMODE_CHANGE notify type as argument
1239 to the `notify' client operation. Affected files are
1240 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
1242 * Added function silc_client_add_server to the client library.
1243 Added support for resolving also channel and server info when
1244 received unknown entity in notify packet. Affected files are
1245 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
1247 * Added function silc_command_get_status to return the command
1248 status from the command reply's argument payload. Affected files
1249 are lib/silccore/silccommand.[ch].
1251 * Added check for KICKED notify type that the kicking is
1252 allowed by the client. Affected file silcd/packet_receive.c.
1254 * Created function silc_get_input which can be used to get input
1255 (echo on or off) from user on command line. Affected files are
1256 lib/silcutil/silcutil.[ch].
1258 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1260 * Optimized silc_server_packet_relay_to_channel function.
1261 Added new function silc_channel_message_payload_encrypt which
1262 can be called directly if channel message payload needs to
1263 be encrypted and is already encoded (no need to call _encode
1264 function). Packet relaying is now done by router without any
1265 extra memory allocations. Affected files are
1266 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
1267 silcd/packet_send.c.
1269 * Fixed the INVITE notify handling. It took wrong arguments
1270 as invite list and invite delete. Affected file is
1271 silcd/packet_receive.c.
1273 * Added check for TOPIC_SET notify type that the topic change is
1274 allowed by the client. Affected file silcd/packet_receive.c.
1276 * Added check for INVITE notify type that inviting is allowed by
1277 the client. Affected file silcd/packet_receive.c.
1279 * Changed the silc_server_client_on_channel to return the
1280 SilcChannelClientEntry as well. Moved the function
1281 silc_server_check_cmode_rights to server_util.[ch].
1282 Affected files are silcd/server_util.[ch], silcd/command.c.
1284 * Added function silc_server_check_umode_rights to check whether
1285 changing client's user mode is allowed. Added check for
1286 UMODE_CHANGE notify type that the umode change is allowed
1287 by the client. Affected files are silcd/server_util.[ch],
1288 silcd/packet_receive.c and silcd/command.c.
1290 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1292 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
1293 ID length. It ignored that ID can be IPv6 based as well.
1294 Affected file lib/silccore/silcpacket.h.
1296 * Fixed the silc_id_id2str and silc_id_str2id to take the
1297 IPv6 address offset's into consideration. Affecte file is
1298 lib/silccore/silcid.c.
1300 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1302 * Fixed the internal Unix scheduler functions to check for
1303 NULL context they may receive. The affected file is
1304 lib/silcutil/unix/silcunixschedule.c.
1306 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
1308 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
1309 can specify different directory with --home command line
1310 parameter. Affected files irssi/src/silc/core/client_ops.c,
1313 * SILC-specific commands aren't now executed if the active server
1314 isn't of SILC-type, so there won't be problems with having
1315 IRC and SILC protocol support in same client. Affected files
1316 irssi/src/silc/core/silc-channels.c, silc-servers.c,
1319 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1321 * Improved the signal support in SILC Schedule. Added new
1322 function silc_schedule_signal_call which is used by application
1323 to mark a signal to be called. It is now safe to perform
1324 any kind of tasks in signal callbacks since it is guaranteed
1325 that the application specified signal callback is called
1326 after the signal is over. Affected files are
1327 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
1329 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1331 * Added `name' field to SilcChannelPrivateKey to represent
1332 application given name for the key. Moved also the context from
1333 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
1334 Added the `name' argument also to the function
1335 silc_client_add_channel_private_key.
1337 Added function silc_client_current_channel_private_key to set the
1338 current channel private key in use.
1340 Added "change" command to KEY command which can be used to change
1341 the current channel private key. Bound the command also to
1342 alt+K (Alt+Shift+k).
1344 Also affected files lib/silcclient/client_channel.c,
1345 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
1347 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1349 * Added silc_rng_get_byte_fast function in to the
1350 lib/silccrypt/silcrng.[ch].
1352 * Changed the interface of silc_packet_assemble and the
1353 silc_packet_send_prepare. If silc_packet_assmble is now
1354 called the application does not call silc_packet_send_prepare
1355 because the library will call it automatically. These
1356 interfaces now also return a reference to the outgoing buffer
1357 which includes the assembled packet, which the application can
1358 use to encrypt the packet.
1360 Affected files are lib/silccore/silcpacket.[ch],
1361 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
1362 silcd/packet_send.c, server_backup.c and packet_receive.c.
1364 * Fixed a packet sending bug on very high load, where outgoing
1365 packet queue wasn't handled correctly and packets got corrupted.
1366 Affected files are lib/silcutil/*/silc*sockconn.c,
1367 lib/silcclient/client.c and silcd/server.c.
1369 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1371 * Added macro SILC_PACKET_DATALEN which can be used during
1372 packet assembling to check whether the data to be added to
1373 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
1374 len is truncated until it fits it.
1376 Added checks for maximum length of channel message payload and
1377 private message payload also.
1379 Added checks for maximum packet length in server and in
1382 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
1383 lib/silcclient/client.c, lib/silccore/silcchannel.c and
1384 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
1385 lib/silcclient/client_prvmsg.c.
1387 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1389 * Added silc_server_packet_queue_purge call to the
1390 silc_server_disconnect_remote to assure that all data in the
1391 queue before disconnecting is sent to the network. Affected
1392 file silcd/server.c.
1394 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1396 * Added the deleting of server's own ID cache entry to the
1397 silc_server_free function. Free also everything else that
1398 has been allocated in silc_server_init. The affected file
1401 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1403 * Added functions silc_parse_version_string, silc_version_to_num,
1404 and silc_ske_parse_version to parse SILC protocol style version
1405 strings. Affected files lib/silcutil/silcutil.[ch] and
1406 lib/silcske/silcske.[ch].
1408 * Added new configuration params: version_protocol, version_software
1409 and version_software_vendor to specify what version the remote
1410 host must at least be to be able to connect to server. The vendor
1411 string can be regex matched too. Added new function
1412 silc_server_connection_allowed to check maximum number of allowed
1413 connections, and allowed versions for incoming connections.
1414 Affected files are silcd/server.c, server_util.[ch] and
1417 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1419 * Added preliminary support for signals in scheduler. The
1420 signals we care about are now blocked always when the scheduler
1421 is locked. This way we can synchronise the use of signal with
1422 scheduler. It is guaranteed that when signal occurs the scheduler
1423 is not locked, and thus new tasks can be safely added to the
1426 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
1427 to silc_schedule_internal_init and silc_schedule_internal_uninit.
1428 Added new platform specific routines
1429 silc_schedule_internal_signals_[un]block and
1430 silc_schedule_internal_signal_[un]register.
1432 Added new functions to SILC Schedule API:
1433 silc_schedule_signal_[un]register. Each signal that application
1434 is going to use should be registered to the scheduler.
1436 Affected files are lib/silcutil/silcschedule.[ch],
1437 lib/silcutil/*/silc*schedule.c.
1439 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1441 * Check for unauthenticated client and server in the
1442 silc_server_new_client and silc_server_new_server functions.
1443 Affected file silcd/packet_receive.c.
1445 * Added function silc_string_is_ascii to check whether given
1446 string is 7-bit ASCII string. Affected files are
1447 lib/silcutil/silcutil.[ch].
1449 * Added function silc_id_is_valid_server_id into the
1450 silcd/serverid.c and added checking for valid Server ID's in
1451 silc_server_new_server. The Server ID must always be based
1452 on the server's public IP address.
1454 * Added logging of DISCONNECT packet message in the server.
1455 Affected file silcd/server.c.
1457 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1459 * Changed all library interfaces that use Global RNG to also
1460 accept SilcRng as argument. Affected files are
1461 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
1462 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
1463 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
1464 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
1465 lib/silccrypt/rsa.c.
1467 * Added function silc_pkcs_generate_key to the
1468 lib/silccrypt/silcpkcs.[ch] for applications so that they
1469 don't need to do pkcs->pkcs->init calls anymore.
1471 * Remove SilcSocketConnection from the SFTP API since it really
1472 wasn't needed there. The application has the information
1473 saved in its contexts anyway and the SFTP layer doesn't need
1474 know about it. Affected files lib/silcsft/silcsftp.h and
1475 lib/silcsftp/sftp_[server/client].c.
1477 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
1478 The SilcSimContext is not SilcSim.
1480 * Fixed possible buffer overflows in silc_id_render in the
1481 lib/silcutil/silcutil.c.
1483 * On EPOC the global crypto module lists are not used at all
1484 in the crypto library. Added support for using the constant
1485 algorithm list on EPOC. Affected files are
1486 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
1489 * Fixed the handling of third parameter of KICKED notify, since
1490 it was mistakenly updated to SILC Protocol 1.0 even though it
1491 is to be included in 1.1. Since it is not in 1.0 it is not
1492 mandatory, and this fix now handles it only if it is provided,
1493 and it is not error if it is not provided. Affected file
1494 lib/silcclient/client_notify.c.
1496 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1498 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
1499 client. Affected file irssi/src/silc/core/client_ops.c.
1501 * Merged with Irssi 0.8.4 from irssi.org CVS.
1503 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1505 * Check for valid socket connection in client entries before
1506 sending any messages. Fixes a crash, but doesn't fix some
1507 other underlaying bug that is lurking there. Affected
1508 file silcd/packet_send.c.
1510 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
1512 * $usermode, $cumode and $cumode_space expandos shouldn't do
1513 anything with non-SILC server records. Affected file
1514 irssi/src/silc/core/silc-expandos.c
1516 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1518 * Fixed the silc_net_check_[host/local]_by_sock to support
1519 IPv6 bound sockets as well. Now they can return IPv6 addresses
1520 as well. Affected file lib/silcutil/silcnet.c.
1522 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
1523 Affected lib/silcutil/unix/silcunixnet.c.
1525 * Fixed ID rendering (at least on some platforms, not NetBSD)
1526 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
1528 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1530 * Added silc_hash_public_key and silc_hash_public_key_compare
1531 functions to be used with SilcHashTable. They can be used to
1532 hash public keys and compare public keys in hash table. Affected
1533 file lib/silcutil/silcutil.[ch].
1535 * Added support for specifying multiple public keys for Client
1536 connection section in server configuration file. This makes it
1537 possible to accept multiple public keys from same host, or to
1538 make a section that accepts any incoming host, and have the
1539 accepted public keys listed in the section.
1541 Added functions silc_sever_[find/get]_public_key, added the
1542 support for this actually to all connection sections but only
1543 the Client section is currently allowed to specify multiple
1546 Affected files are silcd/server.c, server_internal.h,
1547 command.c, protocol.c, server_util.[ch], packet_receive.c.
1549 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1551 * Merged Irssi 0.8.2 from irssi.org CVS.
1553 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1555 * If silc_debug is TRUE, also output standard logging messages
1556 to stderr with the debug output.
1558 Made silc_log_reset_all() flushing all channels before returning.
1559 Also fixed some documentation typos.
1561 Affected files are lib/silcutil/silclog.[ch].
1563 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1565 * Fixed the server to check correctly the amount of connections
1566 from single host, by checking also the type of the connection.
1567 Fixed also the comparison of number of connections and number
1568 of allowed connections. Affected files are silcd/server.c,

1718 the SKE interface a bit.
1720 * Fixed padding problem in PKCS#1. The padding was not actually
1721 random since the random number generator was used incorrectly.
1722 This security bug affects only when encrypting with PKCS#1, and
1723 it is not currently used at all in SILC. SILC only use signing
1724 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.

1787 Affected files irssi/src/silc/core/silc-core.c,
1788 irssi/src/fe-text/silc.c.
1790 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1792 * Added new configuration options and blocks:
1793 keepalive_secs, reconnect_count, reconnect_interval,
1794 reconnect_interval_max, reconnect_keep_trying and

1809 the connection configuration object from the SilcServerConnection
1810 object instead of finding it during the connecting phase.
1811 Added the configuration object to SilcServerConnection struct.
1812 Affected files silcd/server_internal.h, server.c.
1814 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1816 * Add the client on channel after it was resolved at the
1817 channel message receiving, and it was not already on the
1818 channel. Affected file lib/silcclient/client_channel.c.

1840 public key is set. If not set, public key is preferred.
1841 This has effect only when being initiator (responder will try
1844 Added support for authentication with passphrase and public key
1845 at the same time. The passphrase is tried first always since
1846 it is faster to check.
1848 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
1850 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

1896 * Fixed the file transfer's key agreement payload to include
1897 zero port also if the hostname is NULL because it could not
1900 Call file transfer monitor callback now also if error occurs
1901 during key agreement protocol.
1903 Changed the silc_client_file_send interface to return the
1904 SilcClientFileError instead of session id. The session ID
1905 is returned into pointer provided as argument.

1944 the table with foreach callback. The current entry may
1945 become invalid in the callback but it was referenced after
1946 the callback returned.
1948 Do not allow auto rehashing of hash table during the
1949 silc_hash_table_foreach operation, for same reasons as it is
1950 not allowed for SilcHashTableList. Affected files are
1951 lib/silcutil/silchashtable.[ch].

1977 * Fixed a bug in hash table tarversing. While the hash table
1978 is traversed with SilcHashTableList the table must not be
1979 rehashed. It is now guaranteed that auto rehashable tables
1980 are not rehashed while tarversing the list. Also defined that
1981 silc_hash_table_rehash must not be called while tarversing
1982 the table. Added function silc_hash_table_list_reset that must
1983 be called after the tarversing is over. The affected files are
1984 lib/silcutil/silchashtable.[ch].
1986 * Changed all hash table traversing to call the new
1987 silc_hash_table_list_reset in server and in client library.
1989 * Added function silc_client_on_channel to return the
1990 SilcChannelUser entry if the specified client entry is joined
1991 on the specified channel. This is exported to application as
1992 well. Affected files lib/silcclient/client_channel.c, silcapi.h.

2001 lists correctly. Affected file silcd/command.c.
2003 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2005 * When sending JOIN command to router for processing the
2006 sender's old command identifier was not saved back to the
2007 sender's command context, fixed now. The affected file is
2010 * Create the key in JOIN command of the router did not return
2011 the channel key, added check for this. Affected file is
2014 * Fixed a channel ID update bug in JOIN command reply. Do
2015 not directly upgrade the ID but call the function
2016 silc_idlist_replace_channel_id if the ID was changed.
2017 Affected file silcd/command_reply.c.
2019 * Fixed memory leaks from command calling if it would fail.
2020 Affected file silcd/command.c.

2051 user list for the channel again, and server won't be in
2052 desync in some rare circumstances. Affected file is
2053 silcd/packet_receive.c.
2055 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>

2091 * Raised the default connection-retry count from 4 to 7 in
2092 server. Affected file silcd/server.h.
2094 * Cancel any possible reconnect timeouts when we start the
2095 key exchange. Affected file silcd/server.c.
2097 * Do not reconnect on connection failure when SCONNECT was
2098 given. Affected files silcd/server.[ch].
2100 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2102 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
2104 * Fixed the NICK command to always give the unformatted
2105 nickname to the one giving the NICK command. If unformatted
2106 nickname is cached already it will be formatted and the
2107 local entry will always get the unformatted nickname.
2108 Affected file lib/silcclient/idlist.c.
2110 * Fixed some double frees from client library commands.
2111 Affected file is lib/silcclient/command.c.
2113 * Fixed CUMODE command in server to assure that no one can
2114 change founder's mode than the founder itself, there was a
2115 little bug. Affected file silcd/command.c.
2117 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2119 * Removed the SilcClientCommandDestructor from the client
2120 libary, it is not needed anymore. Affected files are
2121 lib/silcclient/silcapi.h, command[_reply].[ch],
2122 client_notify, idlist.c.
2124 * Fixed GETKEY command to first resolve client, and then
2125 resolve the server only if the client was not found, instead
2126 of resolving both at the same time. Affected file is
2127 lib/silcclient/command.c.
2129 * Added silc_client_start_key_exchange_cb and lookup the
2130 remote hostname and IP address before starting the key
2131 exchange with server. The affected file is
2132 lib/silcclient/client.c.
2134 * The server's public key is now saved using the IP address
2135 of the server and not the servername for the filename.
2136 The hostname public key filename is checked as an fall back
2137 method if the IP address based filename is not found.
2139 Fixed the GETKEY command to save the fetched server key
2140 in correct filename.
2142 Print the remote server's hostname now when new key is
2143 received during connection process. Affected file is
2144 irssi/src/silc/core/client_ops.c.
2146 * Return always our own public key to the client if it asks
2147 for it with GETKEY command. Affected file silcd/command.c.
2149 * Removed the use_auto_addr variable from default config
2150 file since it was in wrong section. Affected file is
2153 * Fixed TOPIC_CHANGE notification to not route it when it
2154 was sent using silc_server_send_notify_to_channel function.
2155 Affected file silcd/command.c.
2157 * Fixed silc_server_send_notify_kicked to send the kicker's
2158 Client ID also, it was missing. Affected files are
2159 silcd/command.c, silcd/packet_send.[ch].
2161 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2163 * Do not save client history information in SERVER_SIGNOFF.
2164 Fixes the bug in normal server that it does not detect
2165 the client becoming valid after the server becomes back
2166 online. Affected file silcd/server_util.c.
2168 * Added `sock_error' field into the SilcSocketConnection
2169 context. When error occurs during socket operation (read
2170 or write) the error is saved. Added also new function
2171 silc_socket_get_error to return human readable socket error
2172 message. Affected files are lib/silcutil/silcsockconn.[ch],
2173 lib/silcutil/unix/silcunixsockconn.c, and
2174 lib/silcutil/win32/silcwin32sockconn.c.
2176 * The server now prints the socket error message in the
2177 signoff for client. Affected file silcd/server.c.
2179 * Fixed the `created' channel information sending from router
2180 to server in JOIN command. Checks now whether the channel
2181 really was created or not and set it according that.
2183 Fixed the JOIN command to use the client entry's current
2184 ID during the joining procedure instead of the one it sent
2185 in the command (it is checked though), since it can change
2186 between the packet processing and command processing, and
2187 would just case unnecessary pain in the client end. Affected
2188 file silcd/command.c.
2190 * Fixed a channel key payload sending to use correct channel
2191 ID when the server was forced to change the channel's ID by
2192 router. Router sent the key payload with the old Channel ID.
2193 Affected file silcd/packet_receive.c.
2195 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2197 * Call silc_server_save_channel_key only if the key payload
2198 was provided in the JOIN command's command reply. Affected
2199 file silcd/command_reply.c.
2201 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2203 * Fixed silc_mp_sizeinbase to return the value correctly with
2204 MPI. Affected file lib/silcmath/mp_mpi.c.
2206 * Fixed the stop_server signal to correctly stop the scheduler
2207 and gracefully stop the server when SIGTERM or SIGINT signals
2208 are received. Affected file silcd/silcd.c.
2210 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
2212 * Simple handling of TERM and HUP signals. Also added some log
2213 flushing call around. Affected file is
2216 * Fixed small bugs in silclog.c. Now buffering output will take
2217 effect after 10 seconds since startup: This will ensure that
2218 no important startup messages are lost. Also output redirection
2219 will preserve original format ([Date] [Type] message).
2220 Affected file is lib/silcutil/silclog.c.
2222 * Added two options to the config file, in the logging section:
2223 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
2224 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
2226 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2228 * Do not print the warning about log files not being initialized
2229 more than once to avoid excess logging. Affected file is
2230 lib/silcutil/silclog.c.
2232 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
2233 the SIM copying in make install in Makefile.am.pre.
2235 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2237 * Rewritten silclog APIs. Globally interesting changes follows:
2238 silc_log_set_files() changed to silc_log_set_file().
2239 silc_log_set_callbacks() changed to silc_log_set_callback().
2240 ROBOdoc documented silclog header file.
2241 SilcLogCb now returns bool to wether inihibit the default
2242 handler or not (to keep the old behaviour return always TRUE).
2243 The new APIs should also fix the problem of the
2244 silcd_error.log file that was written in the current directory.
2247 Log files streams will remain opened after silc_log_set_file()
2248 call, means less CPU usage notably on high traffic servers.
2249 File streams are now full buffered, and flushed to the disk
2250 every 5 minutes, lesses HD activity and CPU usage.
2251 Messages can be redirected, allowing admins to configure
2252 one single logfile for all server messages.
2253 the silc_log_quick global variable to activate fast-logging.
2254 Affected files lib/silcutil/silclog.[ch]
2256 * Changed some code to conform new silclog APIs. Affected
2257 files are doc/example_silcd.conf.in, silcd/server.c
2258 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
2261 * Fixed a memory leak that could occur in some situations.
2262 Affected file silcd/serverconfig.c.
2264 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2266 * Added the silc_client_del_client to remove the client from
2267 all channels as well. Affected file lib/silcclient/idlist.c.
2269 * Fixed the client library to correctly remove the client
2270 from all channels when the client entry is being destroyed.
2271 Affected file lib/silcclient/client_notify.c, command.c.
2273 * Added auto-nicking support to the client library. If the
2274 applicatio now sets client->nickname it will be sent to the
2275 server after connecting by the library. This way for example
2276 SILCNICK (or IRCNICK) environment variables will have effect
2277 and always change the nickname automatically to whatever
2278 it is wanted. Affected file lib/silcclient/client.[ch].
2280 * Renamed silc_server_command_bad_chars to the
2281 silc_server_name_bad_chars and moved it to the
2282 silcd/server_util.[ch]. Added also new function
2283 silc_server_name_modify_bad to return nickname that
2284 includes bad characters as new nickname without those
2285 bad characters. This check and modify is now used in
2286 silc_server_new_client when the username is initially set
2287 as nickname, so it must be checked to be valid nickname.
2288 Affected file silcd/packet_receive.c.
2290 * The nickname length is now taken from the packet for real
2291 and not trusted to strlen() since it clearly can return
2292 wrong length for nickname including bad characters. This
2293 also applies to channel names. Affected file silcd/command.c.
2295 * Removed the lib/silcsilm/modules directory. Modules are now
2296 compiled into the lib/silcsim. Fixed the copying of the
2297 modules to follow symbolic links in Makefile.am.pre.
2299 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2301 * Fixed silc_string_regexify list creation. Fixes bugs with
2302 BAN and INVITE commands in server. The affected file is
2303 lib/silcutil/unix/silcunixutil.c.
2305 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2307 * Removed the command destructor entirely from the server's
2308 command and command reply routines. It is not needed, and
2309 its usage was buggy and caused crashes. Affected files are
2310 silcd/command[_reply].[ch].
2312 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2314 * Cancel protocol and NULL sock->protocol if timeout
2315 occurred during protocol. Affected file silcd/server.c.
2317 * Cancel protocol timeouts always before calling the final
2318 callback, to assure that after final callback is called
2319 no other state will be called for the protocol anymore.
2320 Affected file silcd/protocol.c.
2322 * Print error log if incoming connection configuration could
2323 not be found. Affected file silcd/server.c.
2325 * Fixed JOIN command to correctly save the founder mode
2326 to the client on normal SILC server, when the channel
2327 was created by the router. Affected file silcd/command.c.
2329 * Fixed LIST command (hopefully) to send correct reply
2330 packets. Affected file silcd/command.c.
2332 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2334 * The silc_packet_receive_process now returns FALSE if the
2335 read data was invalid packet, and TRUE if it was ok.
2337 The server now checks that if unauthenticated connection
2338 sends data and its processing fails the server will close
2339 the connection since it could be a malicious flooder.
2341 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
2343 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2345 * Make sure the warning about error opening a log file is
2346 printed only once and not everytime it fails (produces
2347 too much useless log). Affected file lib/silcutil/silclog.c.
2349 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2351 * Made the silc_server_daemonise() function more readable.
2352 Affected file silcd/server.c.
2354 * Pid file is now optional, the user may comment it out from
2355 the config file. Removed define SILC_SERVER_PID_FILE, we
2356 don't need a default any longer. Affected file
2357 configure.in.pre, lib/Makefile.am.pre.
2359 * Make some use of the pid file. The server now dies at startup
2360 if it detects a valid pid file on his path. The server would
2361 die anyway in this circumstance, because of the bind() failure.
2362 Affected file silcd/silcd.c.
2364 * No longer compiling lib/dotconf.
2366 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2368 * Fixed JOIN command parsing not to crash. Affected file
2369 lib/silcclient/command.c.
2371 * Fied the NICK_CHANGE notify to add the new client entry
2372 even it is resolved. This removes an <[unknown]> nick
2373 thingy bug in the client. Affected file is
2374 lib/silcclient/client_notify.c.
2376 * Do not try to allocate 0 bytes (efence does not like it)
2377 in lib/silccore/silccomand.c when encoding payload.
2379 * Do not take IRCNICK as nickname in Irssi SILC client since
2380 it is not possible to set nickname before hand connecting
2381 the server (TODO has an entry about adding auto-nicking
2384 * Changed the silc_server_command_pending to check whether
2385 there already exists an pending entry with the specified
2386 command, command identifier and pending callback. This is
2387 to fix IDENTIFY and WHOIS related crashes that may register
2388 multiple pending commands with same identifier. Affected
2389 file silcd/command.c.
2391 * Fixed the server to reconnect to the router even if it
2392 was already reconnecting and EOF was received. This to
2393 fix a possibility that the server wouldn't ever try to
2394 auto-reconnect to the router. Affected file silcd/server.c.
2396 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2398 * Fixed the server's password authentication to use the
2399 length of the locally saved password, and not the one
2400 sent in the packet. Affected file silcd/protocol.c.
2402 * Fixed same password authentication problem in the
2403 Authentication Payload handling routines in
2404 lib/silccore/silcauth.c.
2406 * Yet another password authentication problem fixed with
2407 channel password handling in silcd/command.c.
2409 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2411 * If first character of string in silc_parse_userfqdn is '@'
2412 then do not parse it. Affected file is
2413 lib/silcutil/silcutil.c.
2415 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2417 * Fixed minor bug in IDENTIFY command reply sending, which
2418 caused various weird problems during JOIN when it was
2419 resolving names for users. Affected file silcd/command.c.
2421 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2423 * Fixed the IDENTIFY command reply sending to chech better valid
2424 clients. It was possible to send incomplete list of replies.
2425 Affected file silcd/command.c.
2427 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2429 * Added silc_client_command[s]_[un]register functions now to
2430 dynamically register the commands in client library. Removed
2431 the static table of commands. This allows the client library
2432 to call commands without causing the application to know about
2433 what commands library has called.
2435 Removed the INFO command reply kludge to detect when the command
2436 was called by library. Now library use its own command reply
2437 function for INFO command.
2439 Added function silc_client_command_call to call a command.
2440 Application can use it to call command, not access the structure
2443 Now all commands that are sent by the client library (not
2444 explicitly sent by application) use own command reply functions.
2446 Affected files around lib/silcclient/ and in
2447 irssi/src/silc/core/.
2449 * Fixed the WHOIS command reply sending to chech better valid
2450 clients. It was possible to send incomplete list of replies.
2452 Fixed the WHOIS and IDENTIFY to send the request to router
2453 if normal server did not do it and did not find any results.
2455 Affected file silcd/command.c.
2457 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2459 * Moved the internal data from SilcClient context into its
2460 own file, not accesible to application. Affected files
2461 lib/silcclient/client.h and lib/silcclient/client_internal.h,
2462 and other files in client library.
2464 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2466 * Added doc/examples installation target in Makefile.am.pre.
2469 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2471 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
2472 commands the found client entry will be removed from the
2473 cache, after notifying application about the error. Affected
2474 file lib/silcclient/command_reply.c.
2476 * Changed the /MSG to check for exact nickname user gave, and
2477 not let `nick' match `nick@host' if it is only one found. Now,
2478 user must type the exact nickname (like nick@host2) even if
2479 there are no more than one same nicks found. This is to avoid
2480 a possibility of sending nickname to wrong nickname since
2481 `nick' could match `nick@host'. Affected file is
2482 irssi/src/core/silc-servers.c.
2484 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2486 * Do not print "you are now server operator" or similar when
2487 giving /away command. Affected files are
2488 irssi/src/silc/core/client_ops.c, silc-servers.h.
2490 * Made the silc_server_command_pending_error_check to send
2491 the same command reply payload it received back to the
2492 original sender of the command. This way all arguments
2493 that was received by the server will be received by the
2494 client too. Affected file silcd/command.c.
2496 * Added the silc_idcache_add to return the created cache entry
2497 to a pointer. Affected file lib/silccore/silcidcache.[ch].
2499 * Add global clients to expire if they are not on any channel.
2500 This is because normal server will never know if they signoff
2501 if they are not on any channel. The cache expiry will take
2502 case of these entries. This is done by normal servers only.
2503 The affected files are silcd/command_reply.c,
2504 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
2506 * If server receives invalid ID notification for WHOIS or
2507 IDENTIFY and the ID exists in the lists, it is removed.
2508 Affected file silcd/command_reply.c.
2510 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
2511 in client then client entry that it matches is searched and
2512 the nickname is printed on the screen for user. Affected
2513 file irssi/src/silc/core/client_ops.c.
2515 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2517 * Use cache entry expire time in the LIST command reply to
2518 purge old entries from the cache after the LIST command
2519 reply has been received. This way we don't have non-existent
2520 entries in the cache for too long. Affected file is
2521 silcd/command_reply.c.
2523 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2525 * If we are normal server, and we've not resolved client info
2526 in WHOIS or IDENTIFY from router, and it is global client,
2527 we'll check whether it is on some channel. If it is not
2528 then we cannot be sure about its validity and will resolve it
2529 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
2530 file silcd/command.c.
2532 * Search channel by name (if possible) rather than by ID
2533 in IDENTIFY command's command reply. Affected file is
2534 silcd/command_reply.c.
2536 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2538 * Distribute to the channel passphrase in CMODE_CHANGE notify.
2539 Updated specs and implemented it. Affected file silcd/command.c,
2540 silcd/packet_send.c and silcd/packet_receive.c.
2542 * Implemented the <founder auth> payload handling in the JOIN
2543 command. If provided all conditions for channel joining
2544 except requirement to provide correct passphrase can be
2545 overrided by the channel founder. Updated the protocol specs.
2546 Affected file silcd/command.c.
2548 Added support for founder auth in JOIN command in client
2549 library. Fixed the parsing of the JOIN command now to support
2550 all options as they should be. The affected file is
2551 lib/silcclient/command.c.
2553 * Optimized the WHOIS and IDENTIFY commands to send the request
2554 to router only if it includes nicknames or other names. If
2555 they include only IDs then check the local cache first before
2556 routing. Affected file is silcd/command.c.
2558 * Added channels topic announcements. Affected file is
2559 silcd/packet_receive.c and silcd/server.c.
2561 * Fixed the silc_server_send_notify_topic_set to really destine
2562 the packet to channel. Affected file silcd/packet_send.c.
2564 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
2565 library. Affected file lib/silcclient/client_notify.c.
2567 * Added UMODE announcements. Affected file silcd/server.c.
2569 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2571 * Memory leak fixes in:
2573 lib/silcutil/silcsockconn.c
2574 lib/silcske/silcske.c
2575 lib/silcske/groups.c
2577 lib/silccrypt/silcpkcs.c
2578 lib/silccore/silccommand.c
2579 lib/silccore/silcidcache.c
2584 * ROBOdoc documented the lib/silcske/groups.h file and a
2585 bit changed the interface for better.
2587 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2589 * Update the client entry context in the ID cache after
2590 nick change. Affected file lib/silcclient/command.c.
2591 Fixes the CUMODE command when regaining founder privileges,
2592 and a little WHOIS problem.
2594 * Fixed silc_net_gethostbyname to correctly call the
2595 inet_ntop. Affected file lib/silcutil/silcnet.c.
2597 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2599 * Added IPv6 support checking to the configure.in.pre, added
2600 also --enable-ipv6 option to override the check. Affected
2601 file configure.in.pre.
2603 * The silc_thread_create now calls the start function
2604 directly if threads support is not compiled in. Removes
2605 ugly #ifdef's from generic code. Affected files are
2606 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
2608 * Added silc_net_gethostby[name/addr]_async to asynchronously
2609 resolve. Affected files are lib/silcutil/silcnet.[ch].
2611 * Added support for rendering IPv6 based server, client and
2612 channel IDs. Affected file lib/silcutil/silcutil.c.
2614 * Added support for creating IPv6 based server IDs. Affected
2615 file is silcd/serverid.c.
2617 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2619 * Added silc_net_gethostby[addr/name] into the
2620 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
2621 routines. Added silc_net_is_ip[4/6]. Affected file is
2622 lib/silcutil/unix/silcunixnet.c. All routines that take
2623 address as argument now supports both IPv4 and IPv6 addresses.
2625 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2627 * Fixed LIST command reply sending in server. Affected file
2630 * Server now sends the kicker's client ID in the KICK notify
2631 to the kicked client. Affected file silcd/command.c.
2633 * The client library now parses the kickers client ID and
2634 UI displays it. Affected files lib/silcclient/client_notify.c
2635 and irssi/src/silc/core/silc-channels.c, module-formats.c.
2637 * Made all payload parsing function prototypes consistent.
2638 They all take now const unsigned char * and uint32 pair as
2639 the payload data instead of SilcBuffer. Changes all around
2640 the source tree. Other unsigned char* -> const unsigned char*
2641 changes around the tree as well.
2643 * Optimized SFTP client and server packet sending not to
2644 allocate new buffer for each packet but to recycle the
2645 first allocated buffer. Affected files are
2646 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
2648 * Optimized the SFTP client to use SilcList instead of
2649 SilcDList for requests, because it is faster. Affected file
2650 is lib/silcsftp/sftp_client.c.
2652 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
2653 into lib/silccore/silcid.[ch].
2655 Renamed silcpayload.[ch] into silcargument.[ch].
2657 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2659 * If client entry is deleted with active key agreement
2660 session, abort the session.
2662 The silc_client_abort_key_agreement now calls the completion
2663 callback with new SILC_KEY_AGREEMENT_ABORTED status.
2665 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
2668 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2670 * Don't use __restrict in older GCC's. Affected file is
2671 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
2673 * silc_net_localhost now attempts to reverse lookup the
2674 IP/hostname. Affected file lib/silcutil/silcnet.c.
2676 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
2677 command. It can be used to gain founder privileges at
2678 the same time when joining the channel.
2680 Defined that the SILC_NOTIFY_TYPE_KICKED send the
2681 kicker's client ID as well. Updated protocol specs.
2683 Defined that the server must send SILC_COMMAND_IDENTIFY
2684 command reply with error status to client who sent
2685 private message with invalid client ID.
2687 Updated the protocol specification.
2689 * Added silc_server_send_command_reply to send any
2690 command reply. Affected file silcd/packet_send.[ch].
2692 * Added silc_id_payload_encode_data to encode ID payload
2693 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
2695 * The server now send IDENTIFY command reply with error
2696 status if client ID in private message is invalid. Affected
2697 file silcd/packet_receive.c.
2699 * Save the server key file with server's IP address in
2700 the filename instead of hostname. The affected file is
2701 irssi/src/silc/core/client_ops.c.
2703 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2705 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
2708 * Added libtool support for compiling shared objects in
2709 lib/silcsim. Affected file configure.in.pre and
2710 lib/silcsim/Makefile.am. Original patch by cras.
2712 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2714 * Pid file configuration, and server's config file fixes
2715 patch by toma. Updated CREDITS file.
2717 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2719 * Fixed silc_client_channel_message to not try to decrypt
2720 the message twice if it resolved the destination client
2721 information. This could cause of dropping one channel
2722 message. Affected file lib/silcclient/client_channel.c.
2724 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2726 * Added silc_client_run_one into lib/silcclient/silcapi.h and
2727 lib/silcclient/client.c. This function is used when the SILC
2728 Client is run under some other scheduler, or event loop or
2729 main loop. On GUI applications, for example this may be
2730 desired to used to run the client under the GUI application's
2731 main loop. Typically the GUI application would register an
2732 idle task that calls this function multiple times in a second
2733 to quickly process the SILC specific data.
2735 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2737 * Fixed silc_server_drop() for dropping the supplementary
2738 groups as well, this could cause a security hole on some
2741 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2743 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
2746 * Write PID file after dropping privileges. Added -F option
2747 to run server on foreground. A patch by debolaz.
2748 Affected files silcd/server.c, silcd/silcd.c.
2750 * Fixed MOTD to return the MOTD file server name. Affected
2751 file silcd/command.c.
2753 * Added INFO command reply handling to the Irssi SILC Client.
2754 Affected file irssi/src/silc/core/client_ops.c.
2756 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2758 * Fixed the silc_idcache_list_* routines to really support
2759 the dynamic list. Fixes a crash. Affected file is
2760 lib/silccore/silcidcache.c.
2762 * Fixed the LIST command reply to really call LIST command's
2763 pending callbacks. Affected file silcd/command_reply.c.
2765 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2767 * Update conn->local_entry->nickname after giving NICK
2768 command. Affected file lib/silcclient/command.c.
2770 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
2772 * Added the [pid] option to the silcd configuration file
2774 Affected files: serverconfig.[ch] and silcd.c
2776 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2778 * Save fingerprint in WHOIS command reply in server.
2779 Affected file silcd/command_reply.c.
2781 * Fixed NICK commands pending callback registration.
2782 Affected file lib/silcclient/command.c.
2784 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2786 * Use ++server->cmd_ident when sending commands in server,
2787 instead of random number. Affected file silcd/command.c.
2789 * Fixed GETKEY command reply to call actually GETKEY pending
2790 command callbacks. Affected file silcd/command_reply.c.
2792 * A bit stricter check for nicknames. Check for same nickname
2793 in NICK command also. Affected file silcd/command.c.
2795 * Do not call INFO command everytime client ID changes, only
2796 during first connecting. Affected file lib/silcclient/client.c.
2798 * Set the new nickname only after successful command reply for
2799 NICK command is returned by server. Affected file
2800 lib/silcclient/command.c.
2802 * Remove nicknames from nicklist during server_signoff notify.
2803 Should fix /NAMES bit more. The affected file is
2804 irssi/src/silc/core/silc-channels.c.
2806 * Added `fingerprint' field to the SilcIDListData in the
2807 silcd/idlist.h to hold the fingerprint of the client's
2810 Send the fingerprint of the client's public key in WHOIS
2813 Affected files silcd/command.c, and silcd/idlist.[ch].
2815 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
2816 create fingerprint from given data.
2818 * Show the fingerprint of the client's public key in WHOIS.
2819 Affected files irssi/src/module-formats.[ch] and
2820 irssi/src/silc/core/client_ops.c.
2822 * Format the multiple same nicknames also during JOIN and
2823 NICK_CHANGE notifys. Affected file is
2824 lib/silcclient/client_notify.c.
2826 * Do not print error on screen for invalid private message
2827 payload since it can come if someone is sending private
2828 messages with wrong key. Affected file
2829 lib/silccore/silcprivate.c.
2831 * Fixed multiple concurrent /PING crash. Affected file
2832 lib/silcclient/command.c.
2834 * Changed the wrong ID encoding. All IP addresses must be
2835 in MSB first order in encoded format. They were encoded
2836 wrong and was in LSB format. Affected files are
2837 silcd/serverid.c, lib/silcutil/silcutil.c.
2839 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
2841 * Call the `connect' client operation through the scheduler
2842 in case of error. Affected file lib/silcclient/client.c.
2844 * Call the `failure' client operation even if the error
2845 occurred locally during a protocol. Affected file is
2846 lib/silcclient/protocol.c.
2848 * Added support of sending LIST command to router from normal
2849 server. This way normal server can get list of all channels
2850 in the network too. Fixed the channel list sending in the
2851 server too. Affected files are silcd/command.c, and
2852 silcd/command_reply.[ch].
2854 * Added silc_server_update_channels_by_server and
2855 silc_server_remove_channels_by_server. They are used during
2856 disconnection of primary router and in backup router protocol.
2857 Affected file silcd/server_util.[ch], silcd/server.c and
2858 silcd/server_backup.c.
2860 * Fixed channel adding to global list in IDENTIFY command
2861 reply in server. Affected file silcd/command_reply.c.
2863 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2865 * If the incoming packet type is REKEY or REKEY_DONE process
2866 that packet always synchronously. Fixes yet another MAC
2867 failed error on slow (dialup) connections. Affected file
2868 lib/silcclient/client.c and silcd/server.c.
2870 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2872 * Call check_version SKE callback for initiator too. Affected
2873 file lib/silcske/silcske.c.
2875 * Implemented fix for security hole found in the SKE that was
2876 fixed in the specification few days back; the initiator's
2877 public key is now added to the HASH value computation.
2878 Added backwards support for the old way of doing it too, for
2879 old clients and old servers. Affected file is
2880 lib/silcske/silcske.c.
2882 * Enabled mutual authentication by default in SKE. If initiator
2883 is not providing mutual authentication the responder will
2884 force it. This will provide the proof of posession of the
2885 private key for responder. The affected files are
2886 lib/silcclient/protocol.c and silcd/protocol.c.
2888 * Do not cache anymore the server's public key during SKE.
2889 We do mutual authentication so the proof of posession of
2890 private key is done, and if the server is authenticated in
2891 conn auth protocol with public key we must have the public
2892 key already. Affected file silcd/protocol.c.
2894 * Added new global debug variable: silc_debug_hexdump. If
2895 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
2896 file lib/silcutil/silclog.[ch].
2898 * Fixed compilation warning due to char * -> const char *.
2899 Affected files lib/silcutil/silcnet.h, and
2900 lib/silccore/silcauth.[ch].
2902 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2904 * Fixed CMODE command when new channel key was created. If
2905 the creation failed the old key was removed. Next time giving
2906 same command would crash the server since the old key was
2907 freed already. Affected file silcd/command.c.
2909 * Fixed the silc_server_announce_get_channels to not crash
2910 on reconnect. Affected file silcd/server.c.
2912 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2914 * Added silc_log_set_debug_string function to set a regex
2915 string to match for debug output. Only the function names,
2916 or filenames matching the given debug string is actually
2917 printed. This way it is possible to filter out those debug
2918 strings that user is not interested in.
2920 Fixed a bug in silc_string_regexify.
2922 Affected files lib/silcutil/silclog.[ch], and
2923 lib/silcutil/unix/silcunixutil.c.
2925 * Changed the -d options in both server and Irssi SILC client
2926 to take the debug string as argument. Affected files
2927 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
2929 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2931 * Added silc_hash_babbleprint to create a Bubble Babble
2932 Encoded fingerprint. The encoding is developed by Antti
2933 Huima (draft-huima-babble-01.txt), and it creates human
2934 readable strings out of binary data. Affected file
2935 lib/silccrypt/silchash.[ch].
2937 * Print the babble print now in addition of fingerprint as well
2938 in Irssi SILC client. Affected files are
2939 irssi/src/fe-common/silc/module-formats.[ch],
2940 irssi/src/fe-common/silc/core/client_ops.c.
2942 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2944 * Fixed a security problem found in SKE. The initiator's
2945 public key too is now added to the HASH hash value creation
2946 which is signed by the responder to create the SIGN value.
2947 This will prevent anyone in the middle to lie to the responder
2948 about the initiator's public key. If this is done now, the
2949 man in the middle will get caught. Updated the protocol
2952 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2954 * Better installation directory handling. Configure module
2955 paths and other paths automatically to example_silc* files
2956 in doc/. A patch by toma.
2958 * Fixed compiler warning from MPI library, and from SILC RNG.
2961 * Added SILC_SERVER_PID_FILE to define the pid file for server.
2962 It can be configured with ./configure. A patch by toma.
2964 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2966 * Find correct make to use in prepare-clean. A patch by
2967 toma. Affected file prepare-clean.
2969 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
2971 * Added irssi variables use_auto_addr, auto_bind_ip,
2972 auto_bind_port and auto_public_ip.
2974 * Changed the interface for silc_client_send_key_agreement
2975 in lib/silcclient/silcapi.h
2979 irssi/src/silc/core/silc-core.c
2981 lib/silcclient/silcapi.h
2982 irssi/src/silc/core/silc-channels.c
2983 lib/silcclient/client_keyagr.c
2986 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2988 * Added silc_pkcs_public_key_compare to compare two
2989 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
2991 * Check that the client who set the founder mode on the
2992 channel is the same client that is giving the founder
2993 mode to itself. It is done by comparing the saved public
2994 key (it is saved even in the authentication is passphrase).
2995 Affected file silcd/command.c.
2997 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2999 * Do not process packet for disconnected socket connection.
3000 Affected file lib/silccore/silcpacket.c.
3002 * Process the DISCONNECT packet through scheduler in the
3003 client library. Affected file lib/silcclient/client.c.
3005 * Fixed the silc_client_packet_parse to not to increase
3006 the packet sequence number if the conn->sock and the
3007 current socket connection is not same. This can happen
3008 for example during key agreement when the conn includes
3009 multiple socket connections (listeners). Affected file
3010 lib/silcclient/client.c.
3012 * The sender of the file transfer request now provides also
3013 the pointer (listener) for the key exchange protocol. If
3014 the listener cannot be created then it sends empty key
3015 agreement and lets the receiver provide the listener.
3017 Added `local_ip' and `local_port' arguments to the
3018 silc_client_file_send. If they are provided they are used,
3019 if not then it will attempt to find local IP address, if
3020 not found or bind fails then the remote client will provide
3023 Affected files are lib/silcclient/client_ftp.c and
3024 lib/silcclient/silcapi.h.
3026 * Extended the FILE SEND command to support defining the
3027 local IP and port for key exchange listener. They are
3028 optional. Affected file irssi/src/silc/core/silc-servers.c.
3030 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3032 * Defined to WHOIS command reply the sending of fingerprint
3033 of the client's public key (if the proof of posession of the
3034 corresponding private key is verified by the server).
3035 Updated to the protocol specification.
3037 * Added support of receiving the client's public key's
3038 fingerprint in command reply in client library. Affected
3039 file is lib/silcclient/command_reply.c, and
3040 lib/silcclient/idlist.[ch].
3042 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3044 * Do not send over 128 chars long nickname to the server
3045 in NICK command. Affected file lib/silcclient/command.c.
3047 * Do not send over 256 chars long channel names to the server
3048 in JOIN command. Affected file lib/silcclient/command.c.
3050 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3052 * Assure that silc_server_close_connection cannot be called
3053 twice for same socket context. Affected file is
3056 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3058 * Send error message to application if opening file for
3059 writing during file transfer fails. Affected file is
3060 lib/silcclient/client_ftp.c.
3062 Remove all file transfer sessions for a client that we're
3063 removing from ID cache.
3065 Affected file is lib/silcclient/client_ftp.c.
3067 * Fixed silc_net_addr2bin to return correct address. Affected
3068 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3070 * Fixed file transfer session removing on signoff notify.
3071 Affected file irssi/src/silc/core/silc-servers.c.
3073 * Added the SilcClientFileError to be returned in the monitor
3074 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
3075 Affected file lib/silcclient/silcapi.h.
3077 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3079 * Fixed a crash in silc_client_ftp_free_sessions and
3080 silc_client_ftp_session_free_client. Affected file
3081 lib/silcclient/client_ftp.c.
3083 * Added `disabled' field in the SilcChannelEntry in the server
3084 to indicate if the server entry is disabled. Affected file
3085 silcd/idlist.h, silcd/command[_reply].c.
3087 * SILC server adds now /var/run/silcd.pid everytime it is
3088 started. Affected file silcd/silcd.c.
3090 * Added silc_server_packet_send_clients to send a packet to
3091 the provided table of client entries. Affected file
3092 silcd/packet_send.[ch].
3094 * Fixed a crash in client resolving in client_prvmsg.c in
3095 client library. Affected file lib/silcclient/client_prvmsg.c.
3097 * Do not actually remove the client directly from ID cache
3098 during SERVER_SIGNOFF, but invalidate it. This way we
3099 preserve the WHOWAS info for the client. Affected file
3100 silcd/server_util.c.
3102 * Fixed SERVER_SIGNOFF notify handling in the server. The
3103 server is now able to process incoming SERVER_SIGNOFF notify
3104 for a server that it doesn't even know about. It will remove
3105 the clients provided in the notify. Affected file
3106 silcd/packet_receive.c.
3108 * Check for partial packet in data queue after every packet that
3109 was found from the queue. Return and wait for more data if
3110 there is partial data in queue. Affected file is
3111 lib/silccore/silcpacket.c.
3113 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3115 * Added SilcClietFileError enum to indicate error in
3116 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
3117 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
3118 Affected files lib/silcclient/silcapi.h and
3119 lib/silcclient/client_ftp.c.
3121 * Check that newsize in silc_buffer_realloc is larger than
3122 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
3124 * Added better monitor of file transfers. It now monitors
3125 key agreement protocol during the file transfer too. Added
3126 error reporting too. Affected files
3127 irssi/src/silc/core/silc-servers.c,
3128 irssi/src/fe-common/silc/module-formats.[ch].
3130 * Wrote a help file for FILE command.
3132 * Added silc_rng_global_get_byte_fast to get not-so-secure
3133 random data as fast as possible. Random data is read from
3134 /dev/urandom if available and from the SILC RNG if not
3135 available. It is used in padding generation. Affected file
3136 lib/silccrypt/silcrng.[ch].
3138 * All packets in client library are now processed synchronously.
3139 Optimized packet processing a lot. Affected file
3140 lib/silcclient/client.c.
3142 * All server connection packets are processing synchronously
3143 now in server, to optimize packet processing. Affected file
3146 * Include files are installed now only in Toolkit distribution
3147 if make install is given. Affected files: all Makefile.am's.
3149 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3151 * Assure that silc_client_notify_by_server_resolve does not
3152 resolve the client information multiple times. If it cannot
3153 be found by the first it cannot be found at all. Affected
3154 file lib/silcclient/client_notify.c.
3156 * Fixed WHOWAS command reply calling. Affected file
3157 lib/silcclient/command_reply.c.
3159 * Removed all references to silc_idlist_get_client from the
3160 Irssi SILC client since that call is internal call used by
3161 the library. The Irssi SILC client will use now client
3162 retrieval functions found in silcapi.h.
3164 * Fixed a bug in resolving nickname info before sending
3165 private message. It used freed memory. Affected file
3166 irssi/src/silc/core/silc-servers.c.

3187 * Added silc_net_localip to return local host's IP address.
3188 Affected file lib/silcutil/silcnet.[ch].
3190 * If key exchange or rekey protocol is active for a connection
3191 parse all packets syncronously since there might be packets
3192 in packet queue that we are not able to process without first
3193 processing packets before them. Affected file silcd/server,
3194 lib/silcclient/client.c.
3196 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
3197 whether library should continue processing the packet.
3198 Affected file lib/silccore/silcpacket.h.

3244 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
3245 is incomplete and is being resolved, it won't be resolved
3248 Make sure also that USERS command reply does not resolve
3249 twice information. Affected file is
3250 lib/silcclient/command_reply.c.
3252 Make sure that silc_client_get_clients_by_list does not
3253 resolve twice same information.
3255 * Check for valid client->id in the silc_server_free_client_data.
3256 Affected file silcd/server.c.
3258 * Fixed /GETKEY nick@server not to crash if the server entry
3259 is not found. Affected file lib/silcclient/command.c.
3261 * Fixed the silc_server_check_cmode_rights to check the
3262 requested modes correctly. Affected file silcd/command.c.

3266 * Better checks for non-printable chars in nick added.
3267 Affected file silcd/command.c.
3269 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3271 * Call the silc_server_udpate_servers_by_server in the
3272 primary router that comes back online in the backup resuming
3273 protocol. Otherwise it routes packets wrong. Affected file
3274 silcd/server_util.[ch], silcd/server_backup.c.
3276 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3278 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
3279 lib/silcutil/silcbuffmt.[ch].
3281 * Redefined the SILC packet header to include the padding
3282 length. Affected file lib/silccore/silcpacket.[ch].
3284 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
3285 length for maximum padding up to 128 bytes). Affected
3286 file lib/silccore/silcpacket.h.
3288 * Removed all backwards support for old 0.5.x MAC thingies.
3289 The SILC packet header change makes it impossible to be
3290 backwards compatible.
3292 * Send the ENDING packet with timeout in the backup resuming
3293 protocol. This is to assure that all routers has connected
3294 to the primary router. Affected file silcd/server_backup.c.
3296 * Changed the RNG to take the first IV from random data. It
3297 used to take it from zero actually. Changed the RNG also
3298 to use /dev/urandom during session. /dev/random is used
3299 in initialization. Affected file lib/silccrypt/silcrng.[ch].
3301 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3303 * Changed the SILC packet header to have the first two bytes
3304 (the packet length) encrypted. Affected files aroung the
3305 code tree, lib/silccore/silcpacket.[ch]. Removed the
3306 SilcPacketCheckDecrypt callback. It is not needed anymore
3307 since the silc_packet_receive_process will determine now
3308 whether the packet is normal or special.
3310 * Implemented the unidirectional MAC keys. Affected files
3311 lib/silcske/silcske.c, silcd/protocol.c and
3312 lib/silcclient/protocol.c.
3314 * Implemented the packet sequence number to the MAC computation.
3315 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
3316 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
3317 lib/silcclient/protocol.c.
3319 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3321 * Allow backup router to announce servers. All servers
3322 announced by backup router are added to the global list
3323 automatically. Update hte server's socket to our primary
3324 router also when backup router announces a server.
3325 Affected file silcd/packet_receive.c.
3327 * Do not update the client->router in the function
3328 silc_server_udpate_clients_by_server if the client is on
3329 global list. We might fail to find any specific server
3330 for locally connected clients and local cell clients. They
3331 should still use the `from' and not `to' as client->router.
3332 This fixes backup router resuming protocol. Affected file
3333 silcd/server_util.c.
3335 * Decrease channel statistics count only if the channel
3336 deletion worked. Affected files are silcd/server.c and
3337 silcd/server_util.c.
3339 * Added silc_server_update_servers_by_server to update origin
3340 of all server entries. Used during backup router protocol.
3341 Affected files silcd/server_util.[ch], silcd/server.c. and
3342 silcd/backup_router.c.
3344 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
3345 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
3346 silc_hmac_get_hash and silc_hmac_get_name. Affected file
3347 lib/silccrypt/silchmac.c.
3349 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3351 * Assure that router cannot reroute the same channel message
3352 to the sender. Affected file silcd/packet_receive.c.
3354 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3356 * Made better checks that the channel message is not sent
3357 to the router it came from. Affected file is
3358 silcd/packet_send.c. Fixed memory leak too.
3360 * Announce informations for incoming router connection, but
3361 only after checking if it is replaced by backup router.
3362 Affected file silcd/packet_receive.c.
3364 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3366 * Fixed the backup resuming protocol to work in multiple
3367 router environment. Affected file silcd/server_backup.c.
3369 * Route packet only to one router in the function
3370 silc_server_packet_send_to_channel. Affected file is
3371 silcd/packet_send.c.
3373 * Fixed silc_server_send_notify_dest to set the broadcast
3374 flag. Fixed the silc_server_send_notify_topic to actually
3375 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
3376 Affected file silcd/packet_send.c.
3378 * Changed the SFTP Filesystem interface. Changed the
3379 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
3380 the filesystem operation function. The SilcSFTPFilesystem
3381 is now a context that is allocated by all filesystem allocation
3382 functions and it already includes the operations structure
3383 and filesystem specific context. It is given as argument
3384 now to the silc_sftp_server_start. This made the interface
3385 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
3386 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
3388 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3390 * Changed the backup router adding and getting interfaces
3391 in the server. The router that will be replaced by the
3392 specified backup router is now sent as argument. Affected
3393 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
3396 * Added silc_net_addr2bin_ne to return the binary form of
3397 the IP address in network byte order. Affected files
3398 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
3400 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3402 * Check for existing server ID in silc_server_new_server
3403 and in silc_server_connect_to_router_final and remove the
3404 old entry if it exists. Affected file silcd/packet_receive.c,
3407 * Send the channel message always to only one router, either
3408 in upstream or downstream. Affected file is
3409 silcd/packet_send.c.
3411 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3413 * Wrote the definition of the backup resuming protocol to the
3414 protocol specification.
3416 * Removed one redundant channel key generation from normal
3417 server during joining procedure. Removed one redundant
3418 channel key sending from server to router during joining
3419 procedure. Affected file silcd/command.c.
3421 * Made minor bugfixes to the backup router resuming protocol.
3422 Affected file silcd/server_backup.c, server.c.

3427 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
3430 * Implemented the backup resuming protocol that is used to
3431 resume the primary router position in the cell after the
3432 primary router comes back online. Affected files
3433 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
3434 and silcd/server_util.[ch].
3436 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3438 * Sleep two (2) seconds after sending QUIT command to server.
3439 Affected file lib/silcclient/command.c.
3441 * Assure that if outgoing data buffer is pending do not force
3442 send any data. Affected file silcd/packet_send.c.
3444 * Assure that if outgoing data buffer is pending do not force
3445 send any data. Affected file lib/silcclient/client.c.
3447 * Implemented the backup router support when the primary router
3448 goes down. The servers and routers can now use the backup
3449 router as new primary router without loosing connectivity.
3451 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3453 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
3454 in the server to indicate disabled entry. All data read
3455 from the connection will be ignored and no data is sent
3456 for entry that is disabled. Affected files are
3457 silcd/idlist.h, silcd/server.c.
3459 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3461 * Created SFTP client and server test programs in the
3462 lib/silcsftp/tests directory.
3464 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3466 * Implemented memory filesystem (virtual filesystem) for
3467 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
3470 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3472 * Implemented the SFTP (SSH File Transfer Protocol) to the
3473 lib/silcsftp. It includes SFTP client and SFTP server
3476 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3478 * Moved lib/silccore/silcprotocol.[ch] to the
3479 lib/silcutil library.
3481 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
3482 take variable argument list pointer as argument. Affected
3483 file lib/silcutil/silcbuffmt.[ch].
3485 * Added silc_buffer_set function that is used to set data
3486 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
3487 Affected file lib/silcutil/silcbuffer.h.
3489 * Changed various routines in the core library to use the new
3490 silc_buffer_set instead of allocating new buffer only for
3493 * Added 64-bit value formatting and unformatting support to the
3494 silc_buffer_[un]format routines. Affected file is
3495 lib/silcutil/silcbuffmt.[ch].
3497 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
3498 to includes/bitmove.h.
3500 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3502 * Fixed channel user mode saving in client library. Affected
3503 file lib/silcclient/command[_reply].c.
3505 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3507 * Defined the file transfer to the SILC Protocol. Added
3508 new packet type SILC_PACKET_FTP and defined File Transfer
3509 Payload. The mandatory file transfer protocol is SFTP
3510 (SSH File Transfer Protocol). Affected file in addition
3511 of the internet draft is lib/silccore/silcpacket.h.
3513 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
3514 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
3515 is used as part of backup router protocol when the primary
3516 router of the cell is back online and wishes to resume
3517 the position as primary router.
3519 * Redefined the MAC generation keys in the protocol. The
3520 same key is not used anymore in both direction. Both
3521 direction will now use different keys for sending and
3522 receiving. This fixes a potential security flaw. This
3523 change causes incompatibilities in the protocol.
3525 * Redefined also the MAC computation from the packet.
3526 An packet sequence number is now added to the MAC
3527 computation. This prevents possible replay attacks against
3528 the protocol. This change too causes incompatibilities
3531 Added `sequence' field to the SilcPacketContext to hold
3532 the current sequence number for the packet.
3534 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3536 * Added `created' field to the SilcIDListData in the file
3537 silcd/idlist.h to indicate the time when the entry was
3540 * Added `created' field to the SilcChannelEntry too. Affected
3541 file silcd/idlist.h.
3543 * Added `creation_time' aguments to all the announcement functions
3544 in the server. If it is provided then only the entries that
3545 was created after the provided time frame are actually
3546 announced. Affected file silcd/server.[ch].
3548 * The protocol says that the Channel ID's IP address must be
3549 based on the router's IP address. Added check for this in
3550 the silc_server_new_channel when processing incoming New Channel
3551 Payload. Affected file silcd/packet_receive.c.
3553 * Print out the correct version with --version in SILC client.
3554 Affected file irssi/src/silc/core/silc-core.c.
3556 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3558 * Fixed WHOWAS command to check for completnes of the client
3559 entry always, not just when the command is coming from client.
3560 Affected file silcd/command.c.
3562 * Added new function silc_server_packet_queue_purge to purge the
3563 outgoing data queue to the network. After the function returns
3564 it is guaranteed that the outgoing packet queue is empty.
3565 Affected file silcd/packet_send.[ch].
3567 * Purge the outgoing packet queue in the rekey protocol's final
3568 callback to assure that all rekey packets go to the network
3569 before quitting the protocol. Affected file silcd/server.c.
3571 * Added silc_client_packet_queue_parse as similar function as
3572 in server to the client library. The affected file is
3573 lib/silcclient/client.c.
3575 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3577 * Splitted silcd/server.c and created silcd/server_util.[ch]
3578 for utility functions.
3580 * Added new socket flag SILC_SF_DISABLED to indicate that the
3581 connection is open but nothing can be sent to or received from
3582 the connection. Affected file lib/silcutil/silsockconn.[ch].
3583 The checking for disabled socket is checked in the low level
3584 silc_socket_write and silc_socket_read functions.
3586 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3588 * Allow only nicknames and channel names that fits into the
3589 7-bit unsigned char ASCII set. Affected file silcd/command.c.
3591 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3593 * When processing JOIN command reply in server check that if
3594 the channel exists in our global list we'll move it the local
3595 list. Affected file silcd/command_reply.c.
3597 * Fixed the check whether client is joined on the channel already
3598 in JOIN command. Affected file lib/silcclient/command.c.
3600 * Fixed the JOIN command reply to check whether the channel
3601 already exists. Affected file lib/silcclient/command_reply.c.
3603 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3605 * Added silc_ske_status_string to map the SKE error numbers
3606 to readable strings. The affected files are
3607 lib/silcske/silcske[_status].[ch].
3609 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3611 * Do not show the private channels on the WHOIS channel list
3612 as it is not allowed by the protocol. The affected file is
3615 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3617 * Assure that the packet length digged from the actual packet
3618 is something sensible in the silc_packet_decrypt_rest_special
3619 in lib/silccrypt/silcpacket.c.
3621 * Free and NULL the allocated pointer in silc_hmac_alloc if
3622 the HMAC allocation fails. The affected file is
3623 lib/silccrypt/silchmac.c.
3625 * Print the selected security properties to the log files in
3626 the server. Affected file silcd/protocol.c.
3628 * Add SKE's reference counter even if calling the completion
3629 callback manually. Otherwise it goes negative, although it
3630 does not cause any problems. The affected file is
3631 lib/silcske/silcske.c.
3633 * Remove the client entry with short timeout after giving the
3634 KILL command. Affected file lib/silcclient/command.c.
3636 * Fixed to send error reply in WHOIS and IDENTIFY commands in
3637 case all found clients are already disconnected (WHOWAS would
3638 found them) in the server. Affected file silcd/command.c.
3640 * Update the last_receive (time of last data received) to be
3641 updated only when received private or channel message so that
3642 the idle time showed in WHOIS makes more sense.
3644 * Added boolean field `valid' in to the SilcClientEntry in the
3645 client library to indicate whether the entry is valid or not.
3646 This fixes the nickname change bug on channel when changing
3647 the nickname to be same than the old (like nick to Nick) the
3648 nickname formatter doesn't set the new nick anymore to Nick@host.
3649 Affected file lib/silcclient/idlist.[ch].
3651 * Now actually fixed the nickname changing on disconnection.
3652 Added new function silc_change_nick to the Irssi SILC Client.
3653 Affected file irssi/src/silc/core/client_ops.c,
3654 irssi/src/silc/core/silc-nicklist.[ch].
3656 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3658 * Check that the public key exists in the GETKEY command before
3659 trying to encode it. Affected file silcd/command.c.
3661 * Print some notifications on received public keys with GETKEY
3662 command in the Irssi SILC Client. Affected files are
3663 irssi/src/fe-common/silc/module-formats.[ch],
3664 irssi/src/silc/core/client_ops.c.
3666 * Use IDENTIFY command to resolve the server information in the
3667 GETKEY command instead of INFO command. Affected file
3668 lib/silcclient/command.c.
3670 * All command reply functions in the client library now calls
3671 the pending command reply callbacks even if an error has
3672 occurred. The server has done this a long time and now it was
3673 time to move the client library to this as well. Now all
3674 errors can be delivered back to the pending command reply
3675 callbacks if necessary. Affected files are
3676 lib/silcclient/command[_reply].[ch].
3678 * Change the nickname on disconnection back to the username
3679 because in reconnect the server will enforce it to it anyway.
3680 Affected file irssi/src/silc/core/silc-servers.c.
3682 * Fixed a config file parsing bug in the Irssi SILC client.
3683 Affected file irssi/src/silc/core/clientconfig.c.
3685 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3687 * When printing the channel mode on JOIN, verify that the
3688 channel key and channel's HMAC are valid. Affected file
3689 irssi/src/silc/core/client_ops.c.
3691 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3693 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
3694 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
3695 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
3697 * Removed channel key rekey task deleting from the function
3698 silc_server_save_channel_key. Affected file silcd/server.c.
3699 Added explicit timeout task context instead that is used to
3700 delete the task if we are registering a new task before the
3701 new task has elapsed.
3703 * When channel key rekey occurs the client library now saves
3704 the old channel key for a short period of time (10 seconds) and
3705 is able to use it in case some is still sending channel
3706 messages encrypted with the old key after the rekey. Affected
3707 file lib/silcclient/[idlist.h|client_channel.c].
3709 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3711 * Added check to the silc_server_new_id_real to not accept
3712 new ID if it is the sender's own ID. Affected file is
3713 silcd/packet_receive.c.
3715 * Assure that we do not announce ourself or the one we've
3716 sending our announcements when we're router and are announcing
3717 servers to our primary router. Affected file silcd/server.c.
3719 * Fixed silc_server_command_identify_check_client to assemble
3720 correct WHOIS packet. It send corrupted WHOIS packet and
3721 caused problem with router to router connections. Affected
3722 file silcd/command.c.
3724 Fixed also silc_server_command_whois_check the same way
3725 as for the IDENTIFY command.
3727 * Added new SilcIDListStatus to the server in the SilcIDListData
3728 structure. The status now includes the current status of
3729 the entry (like registered, resolved etc.). Affected file
3730 silcd/idlist.[ch]. Defined a bunch of different status types
3731 as well. This replaced the old boolean registered field as well.
3733 Added resolve_cmd_ident field to the SilcClientEntry structure
3734 too so that if the entry is for example being resolved so
3735 another command may attach to the same pending command reply
3736 without requiring to resolve the same entry again. This concept
3737 should optimize the WHOIS and the IDENTIFY resolving under
3738 heavy load by taking away unnecessary resolving for entries
3739 that are being resolved already.
3741 Added support for adding multiple pending commands for one
3742 command idenfier. Affected file silcd/command[_reply].[ch].
3744 * Fixed WHOIS and IDENTIFY save to remove the cache entry
3745 before deleting the data. Otherwise the hash table will have
3746 freed data in comparison functions. Affected file is
3747 silcd/command_reply.c.
3749 * Fixed silc_idlist_replace_client_id to add the new entry to
3750 the cache with NULL nickname. Otherwise there will be invalid
3751 memory as the nickname after the nickname is freed. Affected
3752 file silcd/packet_receive.c.
3754 * Fixed the silc_idlist_get_clients_by_hash. The entries was
3755 saved into wrong slots because the previous number of entries
3756 was not taken into account. Affected file silcd/idlist.c.
3757 Fixed same thing in silc_idlist_get_clients_by_nickname too.
3759 * If we are router and we receive JOIN notify to a channel that
3760 does not have any users then notified client is marked as the
3761 channel founder, as it is it. The affected file is
3762 silcd/packet_receive.c
3764 * Added to the extended hash table API's table_del_*ext functions
3765 the destructor as argument too, so that the caller can decide
3766 which destructor to use or whether to use destructor at all.
3767 Affected file lib/silcutil/silchashtable.[ch].
3769 * Fixed ID Cache purging. It actually deleted the entries from
3770 the hash table after the data was freed. The hash table ended
3771 up comparing freed memory. The affected file is
3772 lib/silccore/silcidcache.c.
3774 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3776 * Fixed Irssi SILC client's KILL command's HELP syntax.
3778 * The USERS command now resolves the detailed user information
3779 if the userinfo field is missing. Affected file is
3780 lib/silcclient/command_reply.c.
3782 * Do not print error in silc_file_read if the read file does
3783 not exist. Just silently return NULL. Affected file is
3784 lib/silcutil/silcutil.c.
3786 * Fixed the silc_log_output to not wine about NULL filename
3787 and to not create some bogus " " filename. Affected file is
3788 lib/silcutil/silclog.c.
3790 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3792 * Fixed various printing bugs on the user interface in the
3793 Irssi SILC Client. Minor changes that were forgotten from
3796 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3798 * Fixed the configure.in.pre and the compilation and distribution
3799 environment to support the new autoconf 2.52. That version is
3800 now required to compile the CVS trunk.
3802 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3804 * Renamed function silc_parse_nickname to silc_parse_userfqdn
3805 to generally parse user@fqdn format strings. Affected file
3806 lib/silcutil/silcutil.c.
3808 * Added nickname_format and nickname_force_format fields to the
3809 SilcClientParams structure. The first one defines the format
3810 for the nicknames that the library will enforce if the receives
3811 multiple same nicknames. The second one is boolean value and
3812 can be used to force the library to always enforce the format
3813 to the nicknames regardles whether there are multiple nicknames
3814 or not. This configurable formatting was employed to flexibly
3815 support accessing multiple nicknames from the user interface.
3816 The userinterface can now set the nicknames to what ever format
3817 they prefer. Affected file lib/silcclient/silcapi.h.
3819 Added function silc_client_nickname_format to the file
3820 lib/silcclient/idlist.c. It performs the nickname formatting.
3822 Added new field `hostname´ to the SilcClientEntry context.
3823 It holds the hostname of the client. Affected file is
3824 lib/silcclient/idlist.h.
3826 * Irssi SILC Client sets the nicknames in nick@hostn format.
3827 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
3828 irssi/src/silc/core/silc-core.c.
3830 The WHOIS printing now also shows both the real nickname and
3831 the formatted nickname so that user knows how to access the
3832 user if there are multiple same nicknames cached. Affected
3833 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
3834 printing formatting too to take the hostname now as a separate
3835 argument. The Affected file is
3836 irssi/src/fe-common/silc/modules-formats.[ch].
3838 * Changed the silc_client_get_clients_local to accept the formatted
3839 nickname as argument. It accepts the real nickname too but the
3840 formatted nickname can be used to find the true entry from
3841 multiple entries. Affected file lib/silcclient/silcapi.h and
3842 lib/silcclient/idlist.c.
3844 * Added nickname_format_parse field to the SilcClientParams.
3845 It is a callback function provided by the application to parse
3846 the nickname out of the formatted nickname string. The library
3847 calls it to get the nickname from the formatted string. Since
3848 the application generally knows better the format of the nickname
3849 string it parses it instead of the library, even though library
3850 encodes the formatted string. If the callback function is not
3851 provided then the library will use the string as is. The
3852 affected file is lib/silcclient/silcapi.h.
3854 * All the nickname strings passed to the client library in
3855 commands are now expected to be formatted nickname strings.
3856 If the command does not support the formatted nickname string
3857 it will assume that the sent string is the actual nickname.
3858 Affected file lib/silcclient/command.c.
3860 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3862 * Added public key authentication support to OPER and SILCOPER
3863 commands in the client library. Affected file is
3864 lib/silcclient/command.c.
3866 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3868 * Changed the get_auth_methdod client operation to be asynchronous.
3869 It can be async if the application resolves the authentication
3870 method from the server during the negotiation. Added new
3871 SilcGetAuthMeth completion callback that the application will
3872 call after resolving the authentication method.
3874 Added function silc_client_request_authentication_method that
3875 the application can use to resolve the authentication method
3876 from the server. Added also SilcConnectionAuthRequest callback
3877 that the library will call after the server has replied. The
3878 application can call this function if it does not know the
3879 current authentication method.
3881 Affected files are lib/silcclient/client.c and
3882 lib/silcclient/silcapi.h.
3884 * The Irssi SILC client now automatically resolves the authentication
3885 method incase any configuration information is not present (and
3886 currently there never is). The affected file is
3887 irssi/src/silc/core/client_ops.c.
3889 * Fixed public key authentication from the client library.
3890 Affected file lib/silcclient/protocol.c. Changed also the
3891 protocol specification about the public key authentication in
3892 the connection authentication protocol. The actual data to be
3893 signed is now computed with a hash function before signing.
3895 * Fixed the public key authentication from the server as well.
3896 Affected file silcd/protocol.c.
3898 * Removed the mlock()'s from the memory allocation routines.
3899 Affected file lib/silcutil/silcmemory.c. The ./configure does
3900 not check anymore for the mlock(). Affected file is
3903 * Fixed USERS command in server to allow the execution of the
3904 command for private and secret channels if the client sending
3905 the command is on the channel. Affected file silcd/command.c.
3907 * Fixed silc_client_get_clients_local to return the clients
3908 count correctly. It could return wrong value. Affected file
3909 lib/silcclient/idlist.c.
3911 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3913 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
3914 types. The assembler optimizations seemed not to like 64-bit
3915 data types. The assmebler optimizations thus are now enabled
3916 also for BSD systems as opposed to only enable them for Linux.
3918 * Do not check for threads at all on BSD systems. Affected
3919 file configure.in.pre.
3921 * Removed -n and -h options from the Irssi SILC Client since
3922 they are not used in silc.
3924 * Fixed the prime generation to assure that the first digit
3925 of the generated random number is not zero since our conversion
3926 routines does not like number strings that starts with zero
3927 digit. If zero digit is seen the random number is regenerated.
3928 This caused some corrupted RSA keys when the zero first digit
3929 was met. Affected file lib/silcmath/silcprimegen.c.
3931 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3933 * Fixed WIN32 configuration in the ./configure script.
3934 Fixed to include xti.h on environments that has it.
3935 Patches by Carsten Ilchmann and andrew.
3937 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3939 * Changed the silc_id_create_client_id to be collision
3940 resistant. It is now assured that there cannot be created
3941 two same client ID's. I suspect that some weird bugs in
3942 the server were actually caused by duplicate Client IDs.
3943 Affected file silcd/serverid.[ch]. A router receiving
3944 new ID now also assures and informs the sending server
3945 if the ID caused collision.
3947 * Changed the silc_id_create_channel_id to also assure that
3948 there are no collisions.
3950 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3952 * Statement about ignoring the Mutual Authentication flag when
3953 performing rekey with PFS was a bit misleading. It is ignored
3954 if it was set in the initial negotiation, it cannot be even
3955 set in the rekey. Fixed in the ke-auth draft. Started the
3956 new versions of the protocol drafts in the doc/.
3958 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3960 * Fixed a bug in silc_client_command_identify_save when saving
3961 new channel information. The channel name was no duplicated
3962 and caused crash on exit. Affected file is
3963 lib/silcclient/command_reply.c.
3965 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3967 * Fixed the getkey command handling in the server. Send just
3968 empty OK reply to the sender if the key could not be fetched
3969 (but everything else was ok, like the key just was not available).
3970 Changed the public key parameter to optional in the protocol
3971 specs so that empty OK reply can be sent. Affected file
3974 Added a message to Irssi SILC client to tell to user if the
3975 server did not return a public key.
3977 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3979 * Fixed a channel key regeneration bug. It registered new
3980 timeout tasks exponentially until all system resources were
3981 used. Affected file silcd/server.c.
3983 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3985 * Added the SILC Document generator to the scripts/silcdoc.
3986 It can be used to generate the Toolkit Reference Manual out
3987 of the source tree. Internally it will also use the RoboDoc
3988 generator now imported in util/robodoc.
3990 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3992 * Added couple of return's in rekey protocol if error orccurred
3993 during the protocol. The execution must be terminated.
3994 Affected file silcd/protocol.c. Also, terminate the protocol
3995 always with timeout.
3997 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3999 * The client's Client ID was created initally from the wrong
4000 nickname (it could have been in format nick@host) in the
4001 silc_server_new_client. Affected file silcd/packet_receive.c
4003 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4005 * Added some SILC_LOG_ERROR's to various error conditions
4006 if client could not be added to ID cache. Affected files
4007 silcd/packet_receive.c and silcd/server.c.
4009 * When client's sock->user_data is freed, NULL also the
4010 client->router and client->connection pointers. Added check
4011 for these pointers being NULL to various places around the
4012 code. Affected file silcd/server.c.
4014 * Added client->data.registered == TRUE checks to various
4015 places around the code to assure that unregistered client's
4016 are not handled when it is not allowed. Affected file
4019 * Added `bool registered' fields to all
4020 silc_idlist_[server|client]_get_* routines to indicate whether
4021 the fetched client needs to be registered or not. Affected
4022 file silcd/idlist.[ch].
4024 * Add your own entry as registered to the ID cache in the
4025 server. Affected file server.c.
4027 * Fixed a bug in silc_server_new_server. The SilcServer was
4028 set as the new server's context instead of SilcServerEntry.
4029 This naturally caused some weird bugs.
4031 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4033 * Do not delete the channel rekey task when adding it
4034 for in silc_server_create_channel_key.
4036 * Changed the silc_server_create_channel_key to return
4037 TRUE or FALSE to indicate the success of the channel key
4040 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4042 * Fixed MSVC++ project files and added missing files to
4043 Makefiles under win32/.
4045 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4047 * Do not add TCP_NODELAY flag if the operating system
4048 does not have it defined. Affected files are
4049 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
4051 * Fixed buffer overflow from Irssi SILC Client. Affected
4052 file irssi/src/fe-common/core/themes.c.
4054 * Fixed double free in client library in the file
4055 lib/silcclient/client.c when disconnecting from server.
4057 * Applied double free patch from cras to Irssi SILC client.
4058 Affected files irssi/src/core/[modules/expandos].c
4060 * Fixed the disconnection handling to Irssi SILC Client.
4061 The application must call silc_client_close_connection
4062 in ops->connect client operation in case of failure of
4063 the connection. Affected file is
4064 irssi/src/silc/core/client_ops.c.
4066 * Do not set sock->protocol to NULL in the function
4067 silc_client_close_connection after executing the protocol's
4068 final callback since the sock might not be valid anymore.
4069 Affected file lib/silcclient/client.c.
4071 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4073 * Do not enable SILC_THREADS if the linking with libpthread
4074 did not happen. Affected file configure.in.pre.
4076 * Added notion to protocol specification that server must
4077 verify the sent authentication payload with CMODE when
4078 setting the channel founder key. Implemented it to the
4079 server. Affected file silcd/command.c.
4081 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4083 * Added _EXTRA_DIST SILC distribution variable to the
4084 distributions file. It is used to conditionally add extra
4085 files or directories to the specific distribution. Affected
4086 files ./prepare, Makefile.am.pre and distributions.
4088 Removed the `_' from the start of the distribution names.
4091 * Added README.WIN32 for instructions to compile the Toolkit
4094 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4096 * Fixed a double free in disconnection in the server. Affected
4097 file is silcd/server.c.
4099 * Fixed the lib/silcske/groups.c to work now also with GMP
4100 MP library. The string conversion did not work when using
4101 specific base and the base is indicated in the string as well.
4103 * Created win32/ directory which now includes MSVC++ specific
4104 stuff so that toolkit (DLLs) may be compiled with MSVC++.
4105 It will appear only in the toolkit distribution
4107 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4109 * Changed the key material distribution function in case when
4110 the hash output is too short. The data is now concatenated
4111 a bit differently than it used to. Made the change to the
4112 SKE protocol specification.
4114 * Added better GMP detection to configure.in.pre. A patch
4117 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4119 * Fixed a minor bug in SKE that might cause some problem on
4120 some platforms. Affected file lib/silcske/silcske.c.
4122 * Added the cookie checking for initiator in the SKE. It checks
4123 that the responder returns the sent cookie unmodified. The
4124 affected file is lib/silcske/silcske.c. Added new SKE
4125 error type INVALID_COOKIE that can be sent during the
4126 negotiation. Fixed some memory leaks as well.
4128 * Added the "invalid cookie" error message to Irssi SILC client's
4131 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4133 * Added `task_max' field to the SilcClientParams to indicate
4134 the maximum tasks the scheduler can handle. If set to zero,
4135 default values are used. Affected file lib/silcclient/silcapi.h.
4137 * Fixed memory leaks in silc_client_close_connection. Affected
4138 file lib/silcclient/client.c.
4140 * Added silc_client_del_client_entry to client library to free
4141 all memory of given client entry. Affected file is
4142 lib/silcclient/idlist.[ch].
4144 * Added new functions silc_client_del_channel and
4145 silc_client_del_server to delete channel and server entries.
4146 Affected file lib/silcclient/[silcapi.h/idlist.c].
4148 * Removed silc_client_del_client_by_id from silcapi.h.
4150 * Fixed the INFO command to return the server's own info
4151 correctly when querying by Server ID. Affected file is
4154 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4156 * Removed the non-blocking settings in WIN32 code in the
4157 silc_sock_[read/write] and added SleepEx instead. Affected
4158 file lib/silcutil/win32/silcwin32sockconn.c. The availability
4159 of input data is now checked with FIONREAD and ioctlsocket.
4161 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4163 * Call silc_schedule_task_del_by_context in the
4164 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
4165 Affected file lib/silccore/silcprotocol.c.
4167 * Call silc_protocol_cancel for active protocols in the
4168 silc_server_close_connection if the funtion
4169 silc_server_free_sock_user_data has not been called.
4170 Affected file silcd/server.c.
4172 * Generic tasks cannot be deleted using the del_by_fd
4173 task deleting function since generic tasks does not match
4174 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
4176 * Added a notion to SILCOPER help file that the SILCOPER works
4177 only on router server, not on normal server.
4179 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4181 * Added for WIN32 support for the new scheduler as well.
4182 Affected file lib/silcutil/win32/silcwin32schedule.c.
4184 * Fixed the SHA1 implementation to work on various platforms.
4186 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4188 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
4189 API. It is part of the scheduler now. Everything else is
4190 as previously but some functions has changed their names.
4191 Checkout the lib/silcutil/silcschedule.h for the interface.
4192 Updated all applications to use the new interface. Affected
4193 files are lib/silcutil/silcschedule.[ch].
4195 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4197 * Found a bug in the SKE implementation. The HASH value,
4198 specified by the protocol, was not computed correctly. The
4199 public key of the responder was not added to the computation
4200 even though it is mandatory. Affected file lib/silcske/silcske.c.
4201 This unfortunately causes incompatibilities with older
4202 clients and servers.
4204 * Added WIN32 specific network init and uninit functions:
4205 silc_net_win32_init and silc_net_win32_uninit to init and uninit
4206 the Winsock2. Affected file lib/silcutil/silcnet.h and
4207 lib/silcutil/win32/silcwin32net.c.
4209 * Set the socket always to nonblocking mode on WIN32 after
4210 reading data or writing data. Affected file is
4211 lib/silcutil/win32/silcwin32sockconn.c.
4213 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4215 * Fixed various compilation problems under WIN32. Affected
4216 files lib/silcutil/win32/silcwin32thread.c and
4217 lib/silcutil/win32/silcwin32schedule.c.
4219 * Removed all _internal.h #includes from public header
4220 files. Internal headers must never be included from
4223 Removed also the lib/silcske/payload_internal.h file.
4225 * All include files that may be needed (public and some others
4226 included by the public headers) by application developers are
4227 now copied to the ./includes directory. It does not copy any
4228 internal headers. Affected file Makefile.defines.pre and all
4229 Makefile.am's under lib/ and subdirs.
4231 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4233 * Do not change the ~/.silc directory's permissions automatically.
4234 Affected file irssi/src/silc/core/clientutil.c.
4236 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4238 * Do not cancel the protocol in silc_server_close_connection
4239 it might cause recursion. Now cancelled in the function
4240 silc_server_free_sock_user_data. Affected file silcd/server.c.
4242 * Fixed the silc_server_remove_clients_by_server to regenerate
4243 the channel keys correctly finally. Added also new function
4244 silc_server_remove_clients_channels to actually do it.
4245 Affected file silcd/server.c.
4247 * Fixed the silc_server_new_channel to not crash by giving
4248 wrong router to the new channel. Affected file is
4249 silcd/packet_receive.c.
4251 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4253 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
4254 which is given as argument to the silc_client_alloc now.
4255 It can be used to configure the client and set various parameters
4256 that affect the function of the client.
4258 * The USERS command in server did not check whether the channel
4259 is private or secret. Affected file silcd/command.c.
4261 * Added new argument to the USERS command in protocol specification.
4262 The USERS command now can take the channel name as argument
4263 as well. Added support for this in client and server and
4264 updated the protocol specs.
4266 * Completed the GETKEY command in client. It can be now used
4267 to fetch also servers public key not only some clients.
4268 Affected files lib/silcclient/command[_reply].c.
4270 * Added silc_client_get_server to return server entry by the
4271 server name. Affected files lib/silcclient/silcapi.h and
4274 * Redefined the IDENTIFY command in protocol specification to be
4275 more generic. It now can be used to query information about
4276 any entity in the SILC Network, including clients, servers and
4277 channels. The query may be based either the entity's name
4278 or the ID. Added support for this in both client and server.
4280 Affected files silcd/command.c and lib/silcclient/command.c
4281 and command_reply.c.
4283 * Optimized the WHOIS and WHOWAS commands in the server. Removed
4284 the _from_client and _from_server functions. Affected file
4287 * Added silc_client_get_channel_by_id_resolve to the file
4288 lib/silcclient/silcapi.h to resolve channel information by
4289 its ID. Added also silc_client_get_channel_by_id that
4290 does not resolve it from the server.
4292 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4294 * Added SilcServerEntry context into the client library
4295 to represent one server. The INFO command now allocates
4296 these to save the resolved server info. For now on the
4297 client library will also keep information about servers,
4298 connected and resolved with INFO.
4300 The INFO command now allocates the SilcServerEntry context
4301 and saves the server info there. The COMMAND_REPLY in
4302 the INFO now returns the parameters to application in
4303 same order as defined in the protocol specification.
4305 The entries are cached in the client->server_cache.
4307 * The INFO command is now issued after received the Client ID
4308 from the server. Affected file lib/silcclient/client.c.
4310 * The CMODE_CHANGE notify may now return also an SilcServerEntry
4311 to the application as the mode changer might be server.
4312 It is guaranteed that NULL is not returned anymore to the
4313 application. Affected file lib/silcclient/client_notify.c.
4315 The ID Type is now also passed to the application so that
4316 it can check whether the returned entry is SilcClientEntry
4319 Added new function silc_client_get_server_by_id to return
4320 the server entry by ID. Affected files are the
4321 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
4323 * Do not create the channel in the Irssi SILC Client when issuing
4324 the JOIN command but when received the sucessful JOIN command
4325 reply. Otherwise the channel might get created even though we
4326 could not join it. The Affected file is
4327 irssi/src/silc/core/[silc-channels.c/client_ops.c].
4329 * Fixed a channel joining bug in router. The router must also
4330 check the channel modes, invite and ban lists etc. when serving
4331 the JOIN command sent by normal server. Affected file is
4332 silcd/command.c. The router now resolves the client's
4333 information from the server who sent the JOIN command if it
4334 does not know it, and processes the JOIN command only after
4337 * Changed the SilcCommandCb to take new argument; void *context2.
4338 Affected file lib/silccore/silccommand.h
4340 The second argument in the command callbacks in the server now
4341 includes the SilcServerCommandReplyContext if the command was
4342 called as pending command callback from the command reply.
4343 Otherwise it is NULL. When called as pending the status of the
4344 command reply will be checked and if it was erronous the
4345 error will be sent to the original sender of the command.
4346 This way the client always receives the error messages even
4347 though the server was actually the one who received the error
4348 when it resent the command to router, for example. Affected
4349 files silcd/command[_reply].[ch].
4351 * Fixed sending WHOWAS command's error message to client if
4352 the requested client could not be found. It was missing.
4355 * Changed the CMODE and CUMODE commands reply arguments in the
4356 protocol specification. The Channel ID is now sent in both
4357 of the commands to identify the channel. Implemented this
4358 new feature to the client and server. Affected files
4359 lib/silcclient/command_reply.c and silcd/command.c.
4361 * Made better checks for invite and ban lists in the JOIN
4362 command in server. Affected file silcd/command.c.
4364 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4366 * The server now performs the incoming host IP/DNS lookup
4367 using the silc_socket_host_lookup and thus does not block
4368 the server anymore. Affected file silcd/server.c.
4370 * Completed the multi-thread support for SILC Scheduler in
4371 the lib/silcutil/silcschedule.c.
4373 * Fixed the configure.in.pre to detect the pthread correctly
4376 * Fixed a deadlock in silc_task_queue_wakeup in the file
4377 lib/silcutil/silctask.c.
4379 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4381 * Added new function silc_schedule_wakeup that is used in
4382 multi-threaded environment to wakeup the main thread's
4383 schduler. It needs to be used when a thread adds a new task
4384 or removes a task from task queues. After waking up, the
4385 scheduler will detect the task queue changes. If threads
4386 support is not compiled in this function has no effect.
4387 Implemented the wakeup mechanism to both Unix and WIN32
4388 systems. Affected files are lib/silcutil/silcschedule.[ch],
4389 lib/silcutil/unix/silcunixschedule.c and the
4390 lib/silcutil/win32/silcwin32schedule.c.
4392 * Added new function silc_task_queue_wakeup to wakeup the
4393 scheduler by the specified task queue. Affected file
4394 lib/silcutil/silctask.[ch].
4396 * The silc_socket_host_lookup_start now wakes up the scheduler
4397 after adding the timeout task. Affected file is
4398 lib/silcutil/silcsockconn.c.
4400 * The silc_socket_host_lookup is synchronous now if the threads
4401 support is not compiled in. However, the callback is still
4402 called asyncronously through the scheduler, anyway. Affected
4403 file lib/silcutil/silcsockconn.c.
4405 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4407 * Added new function silc_socket_host_lookup to perform
4408 asynchronous IP and FQDN lookups for the socket connection.
4409 Affected files lib/silcutil/silcsockconn.[ch].
4411 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4413 * Added SILC_MUTEX_DEFINE to define the mutex on environments
4414 that may or may not compile the mutex support in.
4416 Changed the silc_mutex_alloc interface. It allocates the
4417 mutex now to the sent pointer and returns TRUE or FALSE.
4419 Affected file lib/silcutil/silcmutex.h.
4421 * Wrote the SILC Task Queue interface to support multi-threads.
4422 Affected file lib/silcutil/silctask.[ch].
4424 * Wrote the SILC Scheduler to support multi-threads. Affected
4425 file lib/silcutil/silcschedule.c.
4427 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4429 * Implemented the SILC Mutex API and SILC Thread API for WIN32
4430 in lib/silcutil/win32/.
4432 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4434 * Defined SILC Mutex API and SILC Thread API and implemented
4435 them for Unix. Affected files are
4436 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
4437 lib/silcutil/unix/silcunixmutex.c and
4438 lib/silcutil/unix/silcunixthread.c.
4440 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4442 * Fixed the silc_server_remove_clients_by_server's channel
4443 key re-generation. The hash table handling was incorrect
4444 and would not work with many channels. Affected file is
4447 * Fixed some memory leaks around the server code.
4449 * Rewrote the silc_server_get_users_on_channel to support IPv6
4450 based Client ID's. Affected file silcd/server.c.
4452 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
4453 specification. However, a separate document must be written
4454 to define the detailed signing procedure and the payload
4455 associated with the flag. Defined the flag to the
4456 lib/silccore/silcchannel.h as well.
4458 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4460 * Changed the dynamic tables to static size tables in the
4461 lib/silccrypt/silchmac.c.
4463 * Removed GCC dependencies from the code. A patch by cras.
4465 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4467 * Do not show the error "Error receiving packet bla bla"
4468 in server if it really was not an error (-2 means that reading
4469 is pending). Affected file silcd/server.c.
4471 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4473 * Fixed a possible crash in silc_server_remove_clients_by_server
4474 in silcd/server.c. Fixed there also some memory leaks.
4476 * Fixed the silc_idlist_replace_client_id. It could replace
4477 wrong key in the hash table. Affected file silcd/idlist.c.
4479 * Do not check whether there are global users on the channel
4480 if the channel->global_users is FALSE. Affected functions
4481 silc_server_remove_from_one_channel and
4482 silc_server_remove_from_channels in silcd/server.c. Also,
4483 do not check if the removed client is local as we can be
4484 sure that global client was not removed from the channel
4485 and checking for global users is not needed.
4487 * The silc_server_remove_clients_by_server now re-generates
4488 the channel keys correctly for those channels that had
4489 clients removed from them. Affected file silcd/server.c.
4491 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4493 * Found the reason of random crashes in the server. We weren't
4494 ignoring the SIGPIPE signal (which can be sent in write())
4495 and it crashed the server. Affected file silcd/silcd.c.
4497 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4499 * Assure that sock->user_data is not NULL in the function
4500 silc_server_packet_send in silcd/packet_send.c.
4502 * Disconnect the remote connection if it could not be added
4503 to any ID lists in the server. The affected file is
4506 * Check in silc_server_packet_send[_real/dest] that the
4507 socket is not disconnecting and ignore the data if it is.
4508 Affected file silcd/packet_send.c.
4510 * Define inline to __inline on native WIN32 compilation.
4511 Affected file includes/silcwin32.h.
4513 * Added some explicit type casts for inline code since MSVC
4514 require them. Affected files lib/silcutil/silcbuffer.h,
4515 lib/trq/silcdlist.h and lib/trq/silclist.h.
4517 * Print warning in log files from now on if the packet
4518 decryption fails. Affected file silcd/server.c.
4520 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4522 * Changed the `say' client operation's interface to accept
4523 new `type' argument to indicate the type of the message sent
4524 by the library. The application may filter the library's
4525 messages according the type. The affected file is the
4526 lib/silcclient/silcapi.h.
4528 * Added two new functions to lib/silcclient/silcapi.h:
4529 silc_client_del_client and silc_client_del_client_by_id.
4530 Affected file lib/silcclient/idlist.c.
4532 * Moved the clientincludes.h from includes/ to silc/ and
4533 serverincludes.h from includes/ to silcd/.
4535 * The modes for the CMODE and CUMODE are now passed as
4536 uint32 for application with COMMAND_REPLY. The affected
4537 file is lib/silcclient/command_reply.c.
4539 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4541 * /WHOIS without arguments shows client's own information.
4542 Affected file lib/silcclient/command.c.
4544 * Changed PING to not accept any arguments. The specs
4545 says that client can ping only the connected server so
4546 requiring an argument is not needed. Affected file is
4547 lib/silcclient/command.c.
4549 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4551 * Fixed a fatal bug in private message sending and reception
4552 encryption and decryption when using private message keys.
4553 The implementation was incorrect and did not follow the
4554 specification. It causd that some of the message were
4555 lost since it did not use the sending and receiving keys
4556 as the protocol suggests. This has been fixed and will cause
4557 incompatibilities with older clients when sending private
4558 message encrypted with private message keys. Affected files
4559 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
4560 and various other in Irssi SILC Client.
4562 Added `responder' boolean argument to the functions
4563 silc_client_add_private_message_key[_ske] to indicate when
4564 the key is added as responder or initiator of the key
4567 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4569 * Removed the silc_ske_check_version function and created
4570 a SilcSKECheckVersion callback. Added also a function
4571 silc_ske_set_callbacks that is now used to set all SKE
4572 callbacks. The callback functions are not given to
4573 the SKE functions anymore, but this function is used to
4576 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
4578 * Added `silc_version' argument to the silc_client_alloc
4579 to define the version of the application for the library.
4580 The library will use the version string to compare it
4581 against the remote host's (usually a server) version
4582 string. Affected file lib/silcclient/silcapi.h
4584 * Added the KE protocol context to Key Agreement context
4585 in client library so that we can abort the SKE if it
4586 is in process when we get timeout. Affected file is
4587 lib/silcclient/client_keyagr.c.
4589 * Do not resolve the client ID forever if it returns in the
4590 first time that such client does not exist. This was done
4591 for example with private message. Affected file is
4592 lib/silcclient/client_prvmsg.c.
4594 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4596 * Do not add regex.h for WIN32. The affected file
4597 includes/silcincludes.h.
4599 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
4600 not work yet 100%. It generates the DLL's automatically
4601 when compiling with --with-win32 under cygwin.
4603 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4605 * lib/contrib/regex.c is not compiled on WIN32.
4607 * Added silc_net_get_socket_opt function to the
4608 lib/silcutil/silcnet.h.
4610 * Added includes/silcwin32.h for WIN32 specific includes
4613 * Do not use ptime structure or any of the posix process
4614 functions on WIN32 in lib/silccrypt/silrng.c.
4616 * Added silc_gettimeofday to provide generic function
4617 for struct timeval on all platforms. Added the function
4618 to lib/silcutil/silcutil.h.
4620 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4622 * Moved the lib/silccore/silcsockconn.[ch] to the utility
4623 library as they clearly belong there. As a plus side we
4624 can make the actual socket connection routines platform
4627 Added also new generic function silc_socket_read and
4628 silc_socket_write (that used to be silc_packet_[read/write].
4629 The implementation of these are platform specific.
4631 * Added WIN32 specific routines of silc_socket_[read/write]
4632 to lib/silcutil/win32/silcwin32sockconn.c.
4634 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4636 * Added preliminary support for native WIN32 compilation under
4637 cygwin (using the -mno-cygwin option for GCC) to the
4638 ./configure.in.pre. The --with-win32 now prepares the
4639 compilation for native WIN32.
4641 * Rewrote the SILC Scheduler interface in the file
4642 lib/silcutil/silcschedule.h. The scheduler is now context
4643 based and does not have anymore any global static scheduler.
4644 Moved the Unix scheduler to the lib/silcutil/unix/ directory
4645 and created lib/silcutil/win32 directory for WIN32 based
4648 * Added Unix specific network routines to the
4649 lib/silcutil/unix/silcunixnet.c and the old
4650 lib/silcutil/silcnet.c includes now only generic routines.
4652 Added WIN32 specific network routines to the
4653 lib/silcutil/win32/silcwin32net.c.
4655 * Added Unix specific utility functions from the
4656 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
4658 * Added WIN32 SILC Scheduler to the file
4659 lib/silcutil/win32/silcwin32schedule.c. The code is of course
4662 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4664 * Do not handle JOIN notify in the server if the target client
4665 is not registered (idata->registered == FALSE). The affected
4666 file is silcd/packet_receive.c.
4668 * Update the nickrec->founder in event_cumode in the Irssi SILC
4669 client. Affected file irssi/src/silc/core/silc-channels.c.
4671 * Fixed the CUMODE_CHANGE notify handling in the server when
4672 server and router are announcing their clients on channels.
4673 Now the mode changes are saved and notified correctly. The
4674 affected file is /silcd/packet_receive.c.
4676 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
4677 They really did not replace the cache entry in the ID Cache.
4678 Now they do that. Affected file silcd/idlist.c.
4680 * Fixed the KICK notify handling in the Irssi SILC client to
4681 update the channel records so that the kicked client does not
4682 appear to be on the channel. The affected file is
4683 irssi/src/silc/core/silc-channels.c.
4685 * Always update the conn->current_channel when executing command
4686 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
4688 * Fixed the KILL notify handling in Irssi SILC client to remove
4689 the killed client on all channels.
4691 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4693 * Fixed the silc_parse_command_line to remove extra spaces
4694 from the start and end of the arguments. Affected file is
4695 lib/silcutil/silcutil.c.
4697 * Cancel and free any active protocol in the function
4698 silc_server_close_connection. Affected file silcd/server.c.
4700 * Cancel and free any active protocol in the function
4701 silc_client_close_connction. Affected file is
4702 lib/silcclient/client.c.
4704 * Do not execute the KILL command for clients that are in
4705 history (ie. they are not in the network). Affected file is
4708 * Fixed KILL notify handling, client does not crash anymore.
4709 Affected file irssi/src/silc/core/silc-channels.c.
4711 * Reduced the default packet buffer size from 2048 to 1024 in
4712 lib/silccore/silcpacket.c.
4714 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
4715 counter to the SKE context that is incresed when the SKE library
4716 performs async operation outside the library. If the outside
4717 process frees the SKE context and FREED status will be set
4718 and the library will detect after the sync operation that the
4719 libary is freed. The affected files are
4720 lib/silcske/silcske[_status].[ch].
4722 * Resolve the client entry information in the function
4723 silc_client_channel_message to assure that NULL pointer is not
4724 passed as client entry to the application. */
4726 * Fixed the task timeout calculation to assure that there is
4727 never negative timeouts. The affected file is
4728 lib/silcutil/silcschedule.c.
4730 * Fixed the channel user mode notification sending in server.
4731 It was sent point-to-point to the router (or to server by router)
4732 but it needs to be destined to a channel. The routines now
4733 supports sending the channel user mode notifys to the channels
4734 when announcing clients and channels. Affected files are
4735 silcd/server.c and silcd/packet_receive.c.
4737 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
4738 It did not actually replace the old channel entry in the cache.
4739 Affected file lib/silcclient/client_notify.c.
4741 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4743 * Fixed a possible crash in silc_packet_send_prepare. It now
4744 assures always that there is enough space in the buffer and
4745 at the tail area of the buffer (for MAC).
4747 Fixed the inbound buffer reallocation in silc_packet_read.
4748 It was old code and did not handle the reallocation correctly.
4751 The affected file is lib/silccore/silcpacket.c.
4753 * Fixed buffer overflow in silc_parse_nickname in the file
4754 lib/silcutil/silcutil.c.
4756 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4758 * make install generates new server keys only if there is not
4761 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4763 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
4764 Added check that if the NOREPLY is set then we will not send
4765 the away message. This avoids infinite loop of away messages
4766 if both clients are away. The affected file is
4767 lib/silcclient/client_prvmsg.c.
4769 * Fixed client crash if /NICK was given without arguments.
4770 Affected file lib/silcclient/command.c.
4772 * Server does not send the invite list in INVITE command back
4773 to the client if the list was not altered. Added this notion
4774 to the protocol spec as well. Affected file silcd/command.c.
4776 Fixed possible crash in INVITE command by checking the
4777 value of silc_server_get_client_route command.
4779 * Fixed the INVITE notify type handling. The arguments are now
4780 taken in correct order and client does not crash. The affected
4781 file is irssi/src/silc/core/silc-channels.c.
4783 Removed the "Inviting xxx to channel" message from the
4784 client library away and let the application handle it.
4785 Affected file lib/silcclient/command.c. Added that message
4786 to Irssi SILC client's message formats.
4788 * Fixed CMODE command crash in client. It now checks the
4789 amount of arguments correctly and does not crash. The affected
4790 file is lib/silcclient/command.c.
4792 * Do not create new channel automatically in silc_channels_join
4793 but check whether the channel by that name already exists.
4794 Affected file irssi/silc/core/silc-channels.c.
4796 * Do not send the SERVER_SIGNOFF to router if the disconnected
4797 entity was the router. Affected file silcd/server.c.
4799 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
4800 SILC client as it was missing from there.
4802 Added the handling of the KICK notify to the Irssi SILC client
4803 as it was missing. Added "you have been kicked" message to
4804 Irssi SILC client's message modules formats.
4806 Added the handing of the KILL notify to the Irssi SILC client
4807 as it was missing. Added the kill message module formats
4810 The affected file is irssi/src/silc/core/silc-channels.c.
4812 * The router did not save the channel mode the server announced.
4813 Affected file silcd/packet_receive.c.
4815 * Fixed a possible crash in INFO command in server. If the
4816 server did not provide the server info it crashed. Affected
4817 file silcd/command.c.
4819 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4821 * Fixed the GETKEY command in the server to check also the
4822 global list. Otherwise the GETKEY would not work correctly
4823 in normal SILC server. Affected file silcd/command.c.
4825 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4827 * Fixed GETKEY crash, it crashed if the command did not succseed.
4829 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4831 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
4832 is now real and not just an macro interface to GMP.
4834 Removed the entire GMP from the source tree and imported new
4835 NSS MPI library instead. Reason for removing GMP is that it is
4836 extremely large and compiles extremely slow. The NSS MPI
4837 is only a few files and compiles in less than 10 seconds.
4838 The speed is also about the same as GMP. The MPI is imported
4839 to lib/silcmath/mpi.
4841 If the system has GMP installed we will still use the GMP.
4842 If it is not then the NSS MPI will be compiled.
4844 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4846 * Merged a long nickname (127 characters long) crash bugfix from
4847 Irssi CVS tree. Affected file irssi/src/core/misc.c.
4849 * Merged a freed memory reference bugfix from Irssi CVS tree.
4850 Affected file irssi/src/core/commands.c.
4852 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4854 * Added the server's public key sving and verification to the
4855 server when performing the SKE. This was missing and the
4856 remote server's (or router's) public key was accepted without
4857 checking whether we have it previously or trust it at all.
4858 Affected file silcd/protocol.c.
4860 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4862 * Check in the silc_server_timeout_remote if protocol is active
4863 and make sure that the protocol's final callback is called so
4864 that all memory if freed. Affected file silcd/server.c.
4866 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4868 * silc_server_whois_send_reply crashed the server if the nickname
4869 was 127 characters long. Affected file silcd/command.c.
4871 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4873 * Added sanity check to the silc_server_new_client. If the hostname
4874 is provided inside username then check that the provided hostname
4875 really is the same as the resolved one. If the hostname was not
4876 resolved then check it from the public key. Affected file is
4877 silcd/packet_receive.c.
4879 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
4880 if the server disconnected us and the connection is not valid
4881 anymore. Affected file irssi/src/silc/core/silc-channels.c.
4883 * Moved the silc_client_[chmode|chumode|chumode_char] away from
4884 the library to the lib/silcutil/silcutil.[ch].
4886 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4888 * Close log file after open. Affected file
4889 lib/silcutil/silclog.c.
4891 * Check whether sock == NULL in silc_client_send_packet and return
4892 if it is. Affected file lib/silcclient/silcclient.c.
4894 * Check rec->entry == NULL in the Irssi SILC Client before
4895 sending the channel message. Affecte file is
4896 irssi/src/silc/core/silc-servers.c.
4898 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4900 * Merged a splitted window bugfix from Irssi CVS tree. The
4901 affected file is irssi/src/fe-text/textbuffer-view.c.
4903 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
4904 It did not print nickname.
4906 * Improved the distributions system a bit.
4908 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4910 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
4911 irssi/src/fe-text/gui-window.c.
4913 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
4914 to in-active server. The affected file is
4915 irssi/src/silc/core/client_ops.c.
4917 * Resolve the client in USERS command reply if the entry does
4918 not have username resolved. The affected file is
4919 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
4920 command to WHOIS command to really resolve stuff. The USERS
4921 is not used any more in any critical section so WHOIS can
4922 be used even though it might be slower than IDENTIFY.
4924 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
4927 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4929 * Changed the protocol API a bit more consistent in the
4930 lib/silccore/silcprotocol.[ch].
4932 * Changed the following headers to ROBODoc format:
4934 lib/silccore/silcpayload.h
4935 lib/silccore/silcprotocol.h
4936 lib/silccore/silcsockconn.h
4938 All core library headers are now formatted.
4940 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4942 * Fixed a bug in Irssi SILC client; do not show that you are
4943 server/router operator if you really are not. Affected file is
4944 irssi/src/silc/core/client_ops.c.
4946 * Renamed silc_command_free_payload to silc_command_payload_free.
4947 Affected file lib/silccore/silccommand.h
4949 * Added silcmath.h to include the prototoypes of various routines
4950 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
4953 * Changed the following headers to ROBODoc format:
4955 lib/silccore/silcchannel.h
4956 lib/silccore/silccommand.h
4957 lib/silccore/silcid.h
4958 lib/silccore/silcidcache.h
4959 lib/silccore/silcmode.h
4960 lib/silccore/silcnotify.h
4961 lib/silccore/silcpacket.h
4962 lib/silcmath/silcmath.h
4964 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4966 * Added checking to the server code not to start the server if
4967 ciphers and stuff are not configured properly. Affected files
4968 silcd/serverconfig.[h] and silcd/server.c.
4970 * Changed the layout of the header files of the public interfaces
4971 in the SILC libraries. The new layout supports ROBODoc
4972 documentation tool (and some others) so that it is easy to create
4973 a library reference manual. All the other headers and source
4974 code must still follow the CodingStyle document. Also source
4975 code must not include these ROBODoc stuffs, only the headers.
4976 Furthermore, all public interface headers must now be named
4977 by using `silc' prefix, example: silcapi.h, silccipher.h.
4978 Some files were renamed due to this. All the other headers
4979 must not be used as public interfaces. I will update the
4980 CodingStyle document later. Changed following headers, so far:
4982 lib/silcclient/silcapi.h
4983 lib/silccore/silcauth.h
4984 lib/silccore/silcprivate.h
4985 lib/silccrypt/silcdh.h
4987 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4991 * Removed silc_client_packet_send_flush from the client library
4992 as it is not needed. Affected file lib/silcclient/client.[ch].
4994 * Added printing of message of unresolved authentication method
4995 to the Irssi SILC client. Added it to the module formats.
4996 Removed the same message from the client library.
4998 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5000 * Added new distribution feature, DISTLABEL. Every distribution
5001 can define own preprocessor label that can be used in the
5002 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
5003 file distributions, acconfig.h.pre and prepare.
5005 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5007 * Added Makefile.defines_int to include the actual definitions
5008 for Makefile.defines.in. Tested the new distribution system,
5009 created distributions and tested installation.
5011 * Added AWAY message printing to the Irssi SILC client. Added
5012 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
5014 * Added SCONNECT command to call the SILC's CONNECT command.
5015 Cannot use CONNECT directly since Irssi uses that internally.
5016 Affected file irssi/src/silc/core/silc-servers.c.
5018 Added ACTION local command. It is same as ME command but takes
5019 the channel as mandatory argument.
5021 Rewrote some of the Irssi's help files to suite for SILC
5024 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5026 * Added Makefile.defines[.in] that should for now on be included
5027 in all Makefile.am file in the source tree. That file includes
5028 all common compilation definitions for SILC source tree.
5030 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5032 * Minor changes to the ./prepare script to change the package
5033 name according the distribution name to the configure.in.
5035 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5037 * Created new distribution system. Added file `distributions'
5038 that defines all the distributions that can be created out of
5039 the SILC source tree. The ./prepare script now reads that
5040 file to determine how to prepare the distributions. The
5041 first argument to the ./prepare is the name of the distribution
5042 and second is the version of the distribution. If given
5043 without arguments it creates the default (toolkit) distribution
5044 with the default version (defined in ./prepare).
5046 All Makefile.am files that are subject to the distributions
5047 are now named as Makefile.am.pre. These are ./Makefile.am
5048 and lib/Makefile.am. Others may be changed later.
5050 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5052 * Added invite list, ban list, some key management and connection
5053 error message printing to module formats in the Irssi SILC client.
5055 * Added new silc_client_set_away_message to set the away message
5056 that is back to the person who sent private message. The
5057 affected file lib/silcclient/silcapi.h and the
5058 lib/silcclient/client_prvmsg.c.
5060 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5062 * Fixed the private message sending in the Irssi SILC client,
5063 added local command KEY to the Irssi SILC client.
5065 Added key management and key agreement message formats to the
5066 irssi/src/fe-common/silc/module-formats.[ch].
5068 Added USERS (alias WHO) printing, server/router operator
5069 indication and LIST command printing to the module formats.
5071 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5073 * Fixed channel joining notify handling, cumode notify handling
5074 from Irssi SILC client.
5076 * Added SILC specific module-formats to the Irssi SILC client so
5077 that SILC specific message hilighting, colors etc is possible.
5078 Affected file irssi/src/fe-common/silc/module-formats.[ch].
5080 Added channel mode, channel user mode, actions, notices,
5081 whois and whowas printing to the the module-formats.c.
5083 * Fixed a bug in channel deletion in the server. The channel
5084 is not left to the cache even if the channel founder auth mode
5085 is set when there are no users anymore on the channel. Affected
5086 file silcd/server.c.
5088 * The silc_net_localhost now resolves the entire hostname including
5089 the domain name. Affected file lib/silcutil/silcnet.c.
5091 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5093 * Changed the ask_passphrase client operation to be ascynchronous.
5094 It has now a completion callback and a context that the
5095 application must call after it has got the passphrase from
5096 the user. Affected files lib/silcclient/silcapi.h,
5097 lib/silcclient/protocol.c, lib/silcclient/command.c and
5100 Added SilcAskPassphrase callback that the application calls
5101 to deliver the passphrase to the library.
5103 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
5104 The public key verification and especially a certificate
5105 verification is asynchronous procedure.
5107 Added new SILC_SKE_STATUS_PENDING status to indicate the
5108 request is pending and a callback will be called to finalize
5111 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
5112 indicate that remote end did not send its public key (or
5113 certificate), even though we require it. Added check for this
5114 condition in the SKE. This was a security bug, now fixed.
5116 Defined new SilcSKEVerifyCbCompletion callback that is called
5117 when the verification process is completed.
5119 The affected files lib/silcske/silcske_status.h and
5120 lib/silcske/silcske.[ch].
5122 * Changed the verify_public_key client operation to be async
5123 as well. Defined SilcVerifyPublicKey callback that is used to
5124 indicate the success of the public key verification process.
5126 Changed the server and client to use the new async client
5129 * Changed the Irssi SILC client's internal scheduler to be called
5130 twice as many times as it used to be. As a result the client
5131 should be a bit faster now. Affected file is
5132 irssi/src/silc/core/silc-core.c.
5134 * Added support to Irssi SILC client of asynchronous public key
5135 verification and passphrase inquiry. Affected file is
5136 irssi/src/silc/core/silc-core.c.
5138 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5140 * Do not say "You have left channel %s" in client library.
5141 Moved it to the application. Affected files are
5142 lib/silcclient/command.c and silc/client_ops.c.
5144 * Fixed silc_client_get_clients. Command context was not
5145 duplicated and was freed memory in the callback. Affected
5146 file lib/silcclient/idlist.c.
5148 * Do not say "you are now talking..." on JOIN command in the
5149 client library. The appliation must handle it.
5151 * Do not say ".. changed topic to" in command reply in the
5152 client libary. The application must handle it.
5154 * Fixed TOPIC command sending in the client library.
5156 * Fixed a memory leak in silc_client_command_free in the file
5157 lib/silcclient/command.c.
5159 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5161 * Imported a modified version of Irssi client to the source tree.
5162 The Irssi will be used to create a new client called
5163 Irssi SILC. Imported to irssi/.
5165 Added silc_core_init_finish function to the Irssi. Affected
5166 file irssi/configure.in.
5168 A lot changes in the Makefile.ams around the irssi tree.
5170 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5172 * Do not rehash if the new size is same as the old size of the
5173 hash table, in the silc_hash_table_rehash*. The affected file
5174 lib/silcutil/silchashtable.c.
5176 * Replaced hash_table_del_by_context calls from the server
5177 (when channel->user_list and client->channels) to the
5178 hash_table_del as it is sufficient and faster.
5180 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5182 * Added silc_hash_table_list, silc_hash_table_get and the
5183 SilcHashTableList structure to provide an alternative way to
5184 traverse the hash table. The affected files are
5185 lib/silcutil/silchashtable.[ch].
5187 * Changed the server's idlist routines to use the hash table
5188 routines to optimize the code.
5190 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5192 * Replaced the client entry's `channel' list and channel entry's
5193 `user_list' list to hash tables for optimized lookup. Changed
5194 the code to use the hash table interface around the code.
5195 Affected file lib/silcd/idlist.[ch].
5197 * Added `auto_rehash' boolean argument to the function
5198 silc_hash_table_alloc to indicate whether the hash table should
5199 auto-rehash when it thinks is appropriate time. It will
5200 increase the hash table size if the there is twice as much
5201 entries in the table than the size of the table, and will
5202 decrease the size if there are twice as less entries than
5203 the size of the table.
5205 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5207 * Fixed silc_xxx_get_supported to not crash at some circumstances.
5209 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5211 * silc_idcache_purge_by_context deletes the entry now by context
5212 as it is supposed to do. Affected file lib/silccore/idcache.c.
5214 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
5215 client is not anymore valid (WHOWAS givens the info) and not
5216 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
5218 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5220 * Removed the `data' and `data_len' arguments from the ID Cache
5221 interfaces and added `name' argument. ID Cache does not handle
5222 anymore the binary data only a names associated with given ID.
5224 * When hashing a Client ID with silc_hash_id the entire ID is
5225 not hashed anymore, instead only the hash of the Client ID is
5226 hashed. This way we can access the Client ID from the cache
5227 with Client ID but with the hash of the ID (which is a hash of
5228 the nickname) as well without any difference in performance.
5230 Added also silc_idcache_find_by_id_one_ext to do one on one
5231 searching when we have the actual ID. Added also function
5232 silc_hash_client_id_compare. The affected files are
5233 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
5235 * When hashing the name associated with a ID it is always done
5236 in lowercase. This way we can access the cache without worrying
5237 about case-sensitivity, even though, for example nicknames are
5240 * Fixed a bug in server with channel message sending. It put
5241 wrong ID type as destination ID. The affected file
5242 silcd/packet_send.c.
5244 * silc_idcache_del_by_context now deletes from all hash tables
5245 by context. Affected file lib/silccore/idcache.c.
5247 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5249 * Changed the client library to use the new ID Cache interface.
5250 Changes around the source tree.
5252 * Added silc_hash_table_rehash_ext to rehash with specific
5253 hash function. Affected file lib/silcutil/silchashtable.[ch].
5255 * Added silc_hash_string_compare to compare two strings in the
5256 hash table. Affected file lib/silcutil/silcutil.[ch].
5258 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5260 * Added new function silc_idcache_del_by_context into the
5261 lib/silccore/idcache.[ch].
5263 * Changed the server's ID list routines to use the new ID Cache
5264 interface. Changes around the source tree.
5266 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5268 * Added silc_hash_table_del[_by_context]_ext functions in to the
5269 lib/silcutil/silchashtable.[ch].
5271 Removed silc_hash_table_find_all* routines and added new
5272 silc_hash_table_find_foreach to replace them.
5274 Added silc_hash_table_replace_ext function as extended
5275 replacing function. Separated the simple hash table interface
5276 from the extended hash table interface in the file
5277 lib/silcutil/silchashtable.h.
5279 * Fixed minor bugs and changed it to use some of the new
5280 hash table functions in lib/silccore/idcache.c
5282 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5284 * Added new function silc_hash_table_find_all to return all keys
5285 in the hash table by the specified key. As the hash table is
5286 collision resistant it also makes it possible to have several
5287 duplicate keys in the hash table. This function may be used to
5288 find all of the keys from the hash.
5290 Added user_context arguments to the SilcHashFunction,
5291 SilcHashCompare and SilcHashDestructor to deliver user specified
5294 Added new fuctions silc_hash_table_find[_all]_ext to do
5295 extended lookup with specified hash and compare functions and
5296 specified user contexts.
5298 Added new function silc_hash_table_add_ext to add the key
5299 with specified hash function and user context.
5301 Added new function silc_hash_table_foreach to traverse all
5302 entrys in the hash table. Added SilcHashForeach callback
5305 Added new function silc_hash_table_del_by_context to delete
5306 the entry only if the context associated with the key matches.
5308 Affected files are lib/silcutil/silchashtable.[ch].
5310 * Removed silc_hash_[server/client/channel]_id and added just
5311 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
5312 silc_hash_id_compare to compare two ID's using as the hash table
5313 comparison function. Added also silc_hash_data to hash
5314 binary data and silc_hash_data_compare to compare it.
5316 * Removed silc_idlist_find_client_by_hash as it is not needed
5317 anymore. Affected file silcd/idlist.[ch].
5319 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
5320 to use internally the SilcHashTable. The new ID Cache is a lot
5321 faster than the old one. Some of the ID Cache interface was also
5322 rewritten and obsolete and stupid functions were removed.
5324 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5326 * Added entry_count field to the SilcHashTable to keep the number
5327 of the entries in the table. Implemented the function
5328 silc_hash_table_rehash. Added new function
5329 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
5331 Fixed a minor bug in silc_hash_table_free.
5333 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
5334 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
5335 into the lib/silcutil/silcutil.[ch].
5337 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5339 * Implemented a collision resistant hash table into the
5340 lib/silcutil/silchashtable[ch]. See the header and the source
5341 for the SilcHashTable API.
5343 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5345 * Merged dotconf version 1.0.2 into lib/dotconf.
5347 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5349 * Do not compile anything in lib/silcsim/* if the SIM support
5350 is not enabled. The tree should now compile without problems
5353 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5355 * Compiled the SILC under cygwin. Compiled and tested briefly
5356 without problems. More tests needed. The SIMs didn't compile
5359 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
5361 * Fixed possible crash in silc_get_username in the
5362 lib/silcutil/silcutil.c.
5364 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5366 * Fixed a va_arg in silc/client_ops.c.
5368 * Oops, RC5 routines were named AES and caused some problems
5369 when not using SIM's. Affected file lib/silccrypt/rc5.c.
5371 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5373 * Added new SilcIDIP structure into the lib/silccore/id.h and
5374 replaced the old `ip' fields from all SILC ID's to that type.
5375 This is a step towards IPv6 support.
5377 The silc_id_get_len takes now the ID as an extra argument.
5378 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
5379 both IPv4 and IPv6 based ID's.
5381 The affected files are lib/silccore/id.[ch] and other files
5382 around the tree using these routines.
5384 * Removed the ID length arguments in server from various
5385 silc_server_send_notify_* routines -> they are not needed
5388 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5390 * Fixed memory leak in silc_encode_pem_file in the file
5391 lib/silcutil/silcutil.c.
5393 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5395 * Check minor version as well in the SKE. Affected files are
5396 silcd/protocol.c and lib/silcclient/protocol.c.
5398 * Added --identifier option to the server so that an identifier
5399 can be when creating the public key for the server. Affected
5400 file is silcd/silcd.c.
5402 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
5403 lib/silccrypt/silcpkcs.c.
5405 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5407 * Register default ciphers and stuff when using -C option with
5408 the server. Affected file sildc/silcd.c.
5410 * Put back the servers public key filename format, it is better
5411 than the new one. For now, the client keys are saved with the
5412 new filename format. The affected file silc/client_ops.c.
5414 * Implemented the Cipher API for the rest of the ciphers that
5415 did not implement it or implemented it the wrong way.
5417 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5419 * Register default ciphers and stuff when using the -S option
5420 in the client. Affected file silc/silc.c. Same also when
5421 creating new key pair with -C option.
5423 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5425 * Fixed the silc_verify_public_key client operation function to
5426 save the public keys differently. The fingerprint is now
5427 used as filename and not the hostname. This way also the
5428 client keys are saved uniquely and not with hostnames. The
5429 affected file is silc/client_ops.c.
5431 * Trimmed the silc_hash_fingerprint function to remove extra
5432 whitespaces from the end of the fingerprint. The affected
5433 file is lib/silccrypt/silchash.c.
5437 * Added silc_cipher_register_default function to register all
5438 default ciphers. It can be used when configuration files
5439 does not exist and the application does not want any specific
5440 ciphers in any specific order.
5442 The SilcDList is now used as silc_cipher_list dynamically
5443 allocated cipher list. Removed the static list all together
5444 and now all ciphers must be allocated to the dynamic list.
5445 The silc_cipher_alloc routine was changed to check only the
5448 All silc_cipher_* routines that used to return int returns
5451 The affected files lib/silccrypt/silccrypt.[ch].
5453 * The same thing was done to silc_hash_* as for silc_cipher_*
5454 routines. Affected files lib/silccrypt/silchash.[ch].
5456 * The same thing was done to silc_pkcs_* as for silc_cipher_*
5457 routines. Affected files lib/silccrypt/silcpkcs.[ch].
5458 Added also silc_pkcs_[un]register[_default] functions.
5459 Removed the data_context from the PKCS API.
5461 * Added silc_hmac_register_default function to register default
5462 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
5463 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
5464 to unregister all hmacs at once.
5466 * Register the default ciphers, hash functions, PKCSs and HMACs
5467 if client's configuration file does not exist. The affected
5470 * The client did not load the hash functions from the SIM
5471 modules at all. Added support for this. Affected file is
5472 silc/clientconfig.c.
5474 * When decoding public key with silc_pkcs_public_key_decode, check
5475 the supported algorithm only if PKCS are registered. Affected
5476 file lib/silccrypt/silcpkcs.c. The same was done with the
5477 silc_pkcs_private_key_decode.
5479 * Fixed the SILC List routines to keep the list always in order.
5480 It used to change the list's order when traversing the list but
5481 not it preserves the order. Affected file lib/trq/silclist.h.
5483 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5485 * Added the client library to use the SilcSocketConnection's
5486 reference counter (by silc_socket_dup) to prevent the bug that
5487 the socket object may be freed underneath async operation.
5489 * The name resolv library checking fixes in the configure.in.pre.
5492 * Created new version of the protocol drafts for future
5493 development. The -03 drafts are the ones that will be changed
5494 in the trunk now and the -02 will remain as they are.
5496 * Send list of CUMODE notifys to the router when announcing
5497 the channel users to the router. Affected file silcd/server.c.
5498 If the router receiving channel founder CUMODE for a channel
5499 that already has channel founder it will send CUMODE notify
5500 to the sender to remove the channel founder rights from the
5501 announced client. Affected file silcd/packet_receive.c.
5503 * The CUMODE notify may now use Server ID as well as the entity
5504 who changes the mode. Updated protocool specs.
5506 * Updated INSTALL and README files.
5508 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5510 * New web pages in the http://silc.pspt.fi. The pages was
5515 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5517 * Implemented the [DenyConnectin] config section in the server.
5518 Added silc_server_config_denied_conn to check whether incoming
5519 connection is denied. Affected file silcd/serverconfig.[ch].
5521 * Do not check the ports when checking the incoming configuration
5522 data if the port is 0, meaning any. Affected file is
5523 silcd/serverconfig.c.
5525 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5527 * Fixed buffer overflow in silc_string_compare in the file
5528 lib/silcutil/silcutil.c.
5530 * Fixed double free in silc_server_command_leave in the file
5533 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5535 * Fixed the version checking in the server. Affected file is
5538 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5540 * Fixed the configuration data fetching when accepting new
5541 connections in the server. Affected file silcd/server.c.
5543 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5545 * Added `sender_entry' argument to the function
5546 silc_server_packet_relay_to_channel so that we can check
5547 whether some destination actually belongs to the same route
5548 the sender belongs (ie, we must not resend the packet to the
5549 sender). Affected file silcd/packet_send.[ch].
5551 * Added `servername' field to the SilcClientEntry in the server
5552 to hold the name of the server where client is from. Affected
5553 file is silcd/idlist.h.
5555 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5557 * Moved the channel message encrypting in the router betwen
5558 router connections from silc_server_channel_message to the
5559 silc_server_packet_relay_to_channel since we want to check
5560 whether we have anybody channel before encrypting anything.
5561 Affected files silcd/packet_[receive/send].c.
5563 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5565 * Fixed the [AdminConnection] server config section to support
5566 multiple entries. Affected file silcd/serverconfig.c.
5568 * Added support into the server to check the validity of the
5569 incoming connection before executing any KE or authentication
5572 * The connection configuration is now saved to the KE and
5573 connection auth protocol contexts and not fetched anymore in
5574 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
5576 * The local hosts listenning address and port is also resolved
5577 now when starting the server. We want to have the socket object
5578 to include the real address and port for the listener. Added
5579 new function silc_net_check_local_by_sock into the files
5580 lib/silcutil/silcnet.[ch].
5582 * Fixed a broadcast bug in server -> do not broadcast if we
5585 * Fixed a routing bug. Do not route broadcast packets ever.
5586 Broadcast packets must be processed always and not routed since
5587 they may be destined to some other host than yourself and thus
5588 would get routed without no good reason. Affected file is
5591 * Added function silc_server_config_is_primary_route to check
5592 whether primary router connection has been configured (a router
5593 configuration that we are initiating). If there is not, we
5594 will assume that there is only two routers in the SILC network
5595 and we will use the incoming router connection as our primary
5596 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
5598 * Changed the order of the broadcasting. Broadcast _after_ the
5599 packet has been processed not before. Affected file is
5602 * Fixed a [ClientConnection] parsing bug. The port was never
5603 parsed correctly thus resulting to port 0. Affected file
5604 silcd/serverconfig.c.
5606 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
5607 argument and did not set the broadcast packet flag. Affected
5608 file silcd/packet_send.c. Fixed same bug in the function
5609 silc_server_send_notify as well.
5611 * If we receive NEW_ID packet for our own ID in the server, ignore
5614 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5618 * Removed the nickname from the Private Message Payload.
5619 Updated the code and the protocol specs.
5621 * Updated protocol specs for submitting to the IETF.
5623 * Tweaked the Random Number Generator a bit. Affected file
5624 lib/silccrypt/silcrng.c. Exported a new function
5625 silc_rng_[global]_add_noise which can be used to add more
5628 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5630 * Do not parse packets with different timeout when protocol
5631 is active -> may cause problem with rekey. Affected file
5634 * When server receives signoff notify it must not create
5635 new channel key if the client is on any channels since the
5636 sender of the signoff notify will create it.
5638 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5640 * Added printing of error messages during SKE protocol from the
5641 failure packet sent by server during SKE. Affected file
5644 * Removed the client's failure_callback handling with timeout
5645 and handle it immediately when received.
5647 * The SKE library returned wrong type in SUCCESS and FAILURE
5648 packets. They must be 32 bit MSB not 16 bit MSB.
5650 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5652 * Ok, rewrote the logic of the re-key and now it seems to work.
5653 I tested it on high traffic with frequent re-keys without
5654 problems. Added hmac_receive (and renamed hmac to hmac_send)
5655 in SilcClientConnection in lib/silcclient/client.h and
5656 in SilcIDListData in silcd/idlist.h. Also, removed the
5657 SilcPacketParserContext's cipher and hmac fields as they are
5658 not needed anymore and actually caused some problems when
5659 the ciphers and hmac's changed underneath the packet parser.
5661 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5663 * If re-key protocol is active then process the incoming packets
5664 synchronously since we must assure that icoming packets encrypted
5665 with the old key is processed before the new keys is set to
5666 use. This is true other packets than for REKEY packets.
5667 Affected file silcd/server.c. The same was done to client library
5668 as well, affected file lib/silcclient/client.c.
5670 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5672 * Fixed bug in client and server to accept the force send if
5673 the packet is send from silc_[server/client]_packet_process
5674 function. Otherwise the packets are never delivered, oops.
5676 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5678 * Disable force sending of packets when REKEY protocol is active.
5679 We must assure that no packet is sent directly when rekey is
5680 performed. All packets must be sent through packet queue.
5681 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
5682 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
5683 function is silc_[server/client]_packet_send_real to check
5686 * Replaced the SIM paths from example config files to
5687 /usr/local/modules. Also, make install creates now
5688 /usr/local/silc/logs directory to hold all the SILC server
5691 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5693 * Made the configure.in.pre work on Solaris. Patch by salo.
5695 * Made all ciphers compatible with non-x86 machines. Defined
5696 CBC mode macros into lib/silccrypt/ciphers_def.h.
5698 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5700 * Fixed the make install.
5702 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5704 * When MAC computation fails the silc_packet_decrypt returned 0
5705 even though it was supposed to return -1. Fixed this. The
5706 affected file is lib/silccore/silcpacket.c.
5708 * Do not replace the config files in /etc/silc (in make install)
5709 if they already exist. Affected file ./Makefile.am.
5711 * Do not send re-key packets immediately but through packet queue.
5712 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
5714 * Changed silc_net_check_host_by_sock to return FALSE if the
5715 IP/DNS could not be resolved. Though, it returns the IP address
5716 now even if it could not resolve it (but returns also FALSE).
5717 Affected file lib/silcutil/silcnet.[ch].
5719 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5721 * Added silc_pkcs_decode_identifier to decode the public key's
5722 identifier. Affected file lib/silccrypt/silpkcs.[ch].
5723 Added also silc_pkcs_free_identifier. Added also new context
5724 SilcPublicKeyIdentifier.
5726 * Added -S option to the silc client. It is used to dump the
5727 contents of the specified public key file.
5729 * Changed the PKCS api to return the public key length when
5730 setting the public key.
5732 * Fixed a fatal bug in the public and private key file loading.
5733 Affected file lib/silccrypt/silcpkcs.c.
5735 * Execute the packet parsing for client with zero (0) timeout
5736 if the protocol is active. Affected file silcd/server.c.
5738 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5740 * Made the key generation options to the silcd program. Added
5741 -C option, equivalent to client's option.
5743 * Added new [ServerKeys] config section to the server. It
5744 configures the server's public and private key.
5746 * Defined generic Public Key Payload into the protocol
5747 specification to send specific type of public keys and
5750 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
5751 public key or certificate.
5753 * Implemented the GETKEY command to the server and to the
5754 client library and on user interface.
5756 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5758 * Made preliminary `make install' work.
5760 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5762 * Added SilcServerRekey context into silcd/idlist.h.
5764 * Added the PFS support as defined in the specification to the
5765 SKE protocol. Affected files lib/silcske/*.c.
5767 * Added `ske_group' field to the SilcServerRekey context to hold
5768 the number of the SKE group that is used with PFS in re-key.
5769 Affected file silcd/idlist.h.
5771 * Added PFS re-key support to the server. Affected file is
5774 * Added silc_protocol_cancel to cancel execution of the next
5775 state of the protocol. Affected file is
5776 lib/silccore/silcprotocol.[ch].
5778 * Added the re-key support with and without PFS to the client
5779 library. Re-key is performed once in an hour, by default.
5781 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
5782 Added silc_client_rekey_callback and silc_client_rekey_final.
5783 Affected files are lib/silcclient/protocol.[ch] and
5784 lib/silcclient/client.[ch].
5786 * Removed the `hmac_key' and `hmac_key_len' fields from the
5787 SilcClientConnection structure; not needed. Affected file is
5788 lib/silcclient/client.h.
5792 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5794 * Do not ask whether user wants to use the negotiated private key
5795 for private messages, just use it. Affected file is
5796 silc/local_command.c.
5798 * Added `send_enc_key' and `enc_key_len' fields to the
5799 SilcIDListData structure since they are needed in the re-key
5800 phase. Affected file is silcd/idlist.[ch].
5802 * Implemented the simple re-key protocol into the server.
5803 Affected files silcd/server.c and silcd/protocol.[ch]. The
5804 re-key will be performed once in an hour, by default.
5806 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
5807 Added silc_server_rekey, silc_server_rekey_callback and
5808 silc_server_rekey_final.
5810 * Removed Tunneled flag from the protocol. Updated the code
5811 and the specifications.
5813 * Adde `pfs' field to the SilcIDListData to indicate whether
5814 the PFS is to be performed in the re-key. Affected file is
5817 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5819 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
5820 int64 of at least the xintXX size. If void * is less that 4
5821 bytes uint32 * will be used. Defined bool as boolean.
5823 * Changed _ALL_ unsigned long and unsigned int to uint32,
5824 unsgined short to uint16 in the source tree.
5826 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
5827 not handle clients that has entry->data.registered == FALSE.
5828 They are not in the network anymore. Affected file is
5831 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5833 * Implemented the sending of the SERVER_SIGNOFF notify in the
5834 server. Affected file is silcd/server.c.
5836 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
5837 Added also silc_notify_payload_encode_args into the
5838 lib/silccore/silcnotify.[ch].
5840 * Implemented ther SERVER_SIGNOFF notify handling in the server.
5841 Affected file silcd/packet_receive.c.
5843 * Implemented the SERVER_SIGNOFF notify handling in the client
5844 library. Affected file lib/silcclient/client_notify.c. Also,
5845 implemnted the printing of the SERVER_SIGNOFF info to the
5846 application. Affected file silc/client_ops.c.
5848 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
5849 if the deleting was successful. Affected file silcd/idlist.[ch].
5851 * Added support for public key authentication in the connection
5852 authentication protocol in the client library. Affected file
5853 lib/silcclient/protocol.c.
5855 * Changed the server's silc_idlist_get_clients_by_* interface
5856 to support already allocated array so that new entries may be
5857 added to pre-allocated array. Affected file silcd/idlist.[ch].
5858 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
5859 and command replies.
5861 * All command reply functions in the server now calls the
5862 pending command callback even if error occured. This way the
5863 error will be delivered to the client as well. Affected files
5864 silcd/command.c and silcd/command_reply.c.
5866 * Fixed INFO command to return local server's info if no server
5867 was provided. Affected file lib/silcclient/command.c.
5869 * Removed RESTART command for good. Updated the code and the
5872 * Rewrote parts of the task system. It is a bit simpler now.
5873 Removed unsued task priorities. The affected files are
5874 lib/silcutil/silctask.[ch].
5876 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5878 * Moved the USERS printing from the library to the application.
5879 Affected files lib/silcclient/command.c and silc/client_ops.c.
5881 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5885 * Added channel key re-key support. The re-key is perfomed
5886 only by the router and is done once in an hour. Added `rekey'
5887 field to the SilcChannelEntry in the server. Affected files
5888 silcd/server.c and silcd/idlist.h.
5890 * Added silc_task_unregister_by_context into the file
5891 lib/silcutil/silctask.[ch].
5893 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5895 * Added SILC_UMODE_GONE mode to indicate when the client is not
5896 present in the SILC network. Added also support to the local
5897 command AWAY that will set this mode. Added support of showing
5898 "xxx is gone" in WHOIS command. The USERS command shows the
5899 gone status as well.
5901 * Fixed setting server and router operator privileges in the
5902 server's UMODE command. Affected file silcd/command.c.
5904 * Merged the SKE KE1 and KE2 payloads into one payload. The
5905 new KE payload is equivalent to the old KE2 payload.
5907 Cleaned up the SKE Start Payload parsing. It now uses the
5908 simple buffer unformatting to do the parsing. A lot faster
5911 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
5912 to the SKE that is used to indicate whether both of the SKE
5913 parties should perform authentication. By default only the
5914 responder performs authentication. By setting this flag also
5915 the initiator must do authentication. By default it is unset
5916 since in normal SKE case, client to server connection, only
5917 the responder should do authentication. When doing SKE between
5918 two clients both should perform authentication. Updated the
5919 code and the protocol specs.
5921 * A little fix to IDENTIFY command in the server. Search the
5922 client first by hash not nickname. Affected file is
5925 * Fixed the silc_client_close_connection to support closing
5926 the client to client connections wihtout deleting too much
5927 data. Affected file lib/silcclient/client.c.
5929 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
5930 are received if protocol used to be active but is not anymore
5931 the application would crash due to NULL pointer dereference.
5932 Affected files silcd/server.c and lib/silcclient/client.c.
5934 * Added `hash' field to the SilcClientConnection to include
5935 the hash function negotiated in the SKE protocol.
5937 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
5938 to set the channel founder authentication data. A client can
5939 claim the founder rights later by providing the authentication
5940 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
5941 This way the channel founder can regain the channel founder
5942 privileges even it is left the channel. This works only on
5943 local server and the client must be connected to the same
5944 server to be able to regain the founder rights. Updated the
5945 protocol specs accordingly.
5947 Added support to the CMODE command in the client to set the
5948 founder auth data. Read the README to see how to set it.
5950 Added support to the CUMODE command to claim the founder
5951 rights. Read the README to see how to do it.
5953 Added support for the founder authentication to the Channel
5954 Entry in the server. Affected file silcd/idlist.h.
5956 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
5957 server's CMODE command. Affected file silcd/command.c.
5959 * Added the following new functions into lib/silccore/silcauth.[ch]:
5960 silc_auth_get_method and silc_auth_get_data.
5962 * The server now saves the remote hosts public key to the
5963 SilcIDListData pointer. Affected file silcd/protocol.c.
5965 * The normal server now does not remove the channel entry from
5966 the cache if the founder authentication data is set. It used
5967 to remove it if the founder was the last one on the channel on
5968 the server and left the channel. The auth data is saved and
5969 if the channel is re-joined later the old entry is used with
5970 the old auth data. Affected files silcd/command_reply.c and
5973 * Removed the `pkcs' field from the SilcIDListData structure
5974 in the server; it is not used. Affected file silcd/idlist.h.
5976 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5978 * Fixed packet processing on slow links. Partial packets were
5979 never re-processed because the incoming data buffer was cleared
5980 by the application. Application must not directly clear the
5981 sock->inbuf, the packet processing routines handle it. Fixed
5982 this in client library and in server.
5984 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5986 * Fixed the WHOIS and IDENTIFY send reply function to really
5987 check whether to send list or just one entry. Affected file
5990 * Cleaned up the LEAVE command's channel key distribution. The
5991 affected file silcd/command.c.
5993 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
5994 can enforce the channel mode as well. In that case the ID
5995 includes the ID of the server. The code now enforces the
5996 mode change if the router have different mode than the server.
5998 * The notify client operation with CMODE_CHANGE notify can now
5999 return NULL client_entry pointer if the CMODE was not changed
6000 by client. Application must check for this.
6002 * Added <Server ID> argument to INFO command to support server
6003 info fetching by Server ID.
6005 * Added silc_server_announce_get_channel_users to get assembled
6006 packets of channel users of the specified channel. Affected
6007 file silcd/server.[ch].
6009 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
6010 was freed underneath the ID Cache.
6012 * Re-announce clients when the server received CHANNEL_CHANGE
6013 notify from the router. Affected file silcd/packet_send.c.
6015 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6017 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
6018 crashed since it did not handle the fact that there is no cipher
6019 called "3" and didn't check the error condition. Now fixed.
6021 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
6022 flag. It can be used to send message requests.
6024 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6026 * Implemented the RESTART command in the client.
6028 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
6029 notice type messages. Added notice printing to the user
6032 * The channel keys are not re-generated if the channel's mode
6033 is PRIVKEY, ie private key on the channel exists. Affected
6034 files silcd/server.c and silcd/command.c.
6036 * Fixed a little bug in channel message delivery when channel
6037 private keys are set in the server. Affected file is
6038 silcd/packet_send.c.
6040 * Changed the setting on channel->on_channel = TRUE from the
6041 silc_client_save_channel_key to the JOIN command reply. The
6042 key payload is not received if the private channel key is set.
6043 Affected file lib/silcclient/command_reply.c and the
6044 lib/silcclient/client_channel.c.
6046 * When the CMODE_CHANGE notify is sent and the channel private
6047 key mode is removed the channel key must be re-generated in
6048 other cells as well. Added this support for the router in the
6049 silcd/packet_receive.c.
6051 * Added new local command NOTICE to send notice message on
6052 channel. Affected file silc/local_command.[ch].
6054 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6056 * Added new local command ME to the client. It is used to send
6057 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
6058 some action. Affected file silc/local_command.[ch].
6060 * Changed channel_message and private_message client operations
6061 to deliver the message flags to the application. Added also
6062 the `flags' arguments to the silc_client_send_channel_message
6063 and silc_client_send_private_message functions. Affected file
6066 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6068 * Redefined the Private Message Payload to support private message
6069 keys and to support the new private message flags. Updated
6070 the protocol specs. Flags makes it possible to have for example
6071 CTCP style messages.
6073 * Added new type SilcPrivateMessagePayload and defined an API
6074 for it in the lib/silcclient/silcprivate.[ch].
6076 * Tested private message private keys successfully. Tested the
6077 private message key set, unset and list commands with the new
6080 * Redefined the Channel Message Payload to include the channel
6081 message flags (equal with private message flags) to support
6082 for example CTCP style messages.
6084 * Defined some of the message (for channel and private message)
6085 flags. Updated the protocol specs and added the flags to the
6086 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
6088 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6090 * Added SilcKeyAgreementStatus type to the key agreement routines
6091 to indicate the current status and error if one occured.
6092 The status types are defined in the lib/silcclient/silcapi.h.
6094 * Added new local command KEY that is used to set and unset private
6095 keys for channels, set and unset private keys for private messages
6096 with remote clients and to send key agreement requests and
6097 negotiate the key agreement protocol with remote client. The
6098 key agreement is supported only to negotiate private message keys,
6099 it currently cannot be used to negotiate private keys for channels,
6100 as it is not convenient for that purpose.
6102 * Fixed a minor pending callback setting bug in the function
6103 silc_client_get_client_by_id_resolve, now the function works.
6104 Affected file lib/silcclient/idlist.c.
6106 * Added function silc_net_get_local_port to get local bound
6107 port by socket. Added to lib/silcutil/silcnet.[ch].
6109 * Added `sockets' and `sockets_count' fields to the SilcClient
6110 object. They hold the sockets of the listenning sockets in
6111 the client. Listenning sockets may be for example the key
6112 agreement server. Affected file lib/silcclient/client.[ch].
6113 Added functions the silc_client_add_socket and the
6114 silc_client_del_socket. They are exported to the application
6117 * Added ~./silc/clientkeys to support other client's public keys.
6119 * Renamed verify_server_key client operation to verify_public_key
6120 and added one argument to indicate the type of the connection
6121 (server, client etc.).
6123 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6125 * Added silc_server_connection_auth_request to handle the
6126 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
6127 silcd/packet_receive.[ch].
6129 * Added silc_server_send_connection_auth_request into the
6130 silcd/packet_send.c to send the connection auth request packet.
6132 * Cleaned up the silcd/protocol.c a bit and fixed some memory
6135 * Fixed the public key authentication in responder side in the
6136 server. The `auth_data' pointer includes the SilcPublicKey
6137 not the path to the public key. Affected file silcd/protocol.c.
6139 * Implemented the public key authentication in the initiator side
6140 in the server. Affected file silcd/protocol.c.
6142 * Removed the [RedirectClient] config section from the server
6143 configuration. Is not needed and I don't want to implement it.
6145 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6147 * Cleaned up the CMODE command in the server. It now works
6148 correctly and supports all the modes defined in the protocol.
6149 Affected file is silcd/command.c.
6151 * Added `hmac_name' field to the SilcChannelEntry in the server
6152 to hold the default HMAC of the channel. It can be set when
6153 creating the channel (with JOIN command). Affected files
6156 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
6157 type to indicate the change of the current cipher and hmac
6158 on the channel. Client can safely ignore the <cipher> argument
6159 (if it chooses to do so) since the CHANNEL_KEY packet will
6160 force the channel key change anyway. The <hmac> argument is
6161 important since the client is responsible of setting the new
6162 HMAC and the hmac key into use.
6164 * Fixed the CMODE command in the client library as well.
6166 * Tested CMODE command in router environment successfully.
6168 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6170 * Show the version of the remote client (or server) when connecting
6171 to the server. It is logged to the log file. Affected file
6172 is silcd/protocol.c.
6174 * Fixed the KILLED notify handling in the client library. The
6175 client must be removed from all channels when receiving the
6178 Also, do not remove the client entry when giving the KILL
6179 command but when the KILLED notify is received.
6181 * Removed silc_idlist_find_client_by_nickname from the server.
6182 Not needed anymore. Affected files silcd/idlist.[ch].
6184 * Implemented the CHANNEL_CHANGE notify type handling to the
6185 server. Affected file silcd/server.c.
6189 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6191 * Added silc_server_send_notify_invite to send the INVITE
6192 notify between routers.
6194 * Implemented the INVITE command correctly to the server.
6196 * Implemented the INVITE notify type handling in the server.
6198 * Implemented the INVITE command to the client library and on the
6201 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6203 * Added function silc_server_get_client_resolve to find the
6204 client entry by ID from all ID lists and then resolve it
6205 (using WHOIS) if it cannot be found. Affected file is
6208 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6210 * Implemented the BAN command to the client library.
6212 * The JOIN command in the server now checks the invite list
6215 * Changed the silc_command_reply_payload_encode_va and the
6216 silc_command_payload_encode_va to support that if argument is
6217 NULL it ignores and checks the next argument. Affected file
6218 lib/silccore/silccommand.c.
6220 * Added silc_server_send_notify_ban to send the BAN notify
6221 type between routers.
6223 * Chaned the silc_notify_payload_encode to support that if
6224 argument is NULL it ignores and checks the next argument.
6225 Affected file lib/silccore/silcnotify.c.
6227 * Tested ban lists in router environment successfully.
6229 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6231 * Implemented BAN command to the server, in silcd/command.[ch].
6233 * Removed the BAN and INVITE_LIST modes from the CMODE command
6236 * Added function silc_string_match to regex match two strings.
6237 Affected files lib/silcutil/silcutil.[ch].
6239 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6241 * Redefined parts of the SilcChannelEntry in the server to support
6242 the new ban and invite lists.
6244 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6246 * Redefined the INVITE command. The same command can be used to
6247 invite individuals to the channel but also to manage the invite
6248 list of the channel (to add to and remove from the invite list).
6249 Updated the protocol specs.
6251 * Added new command SILC_COMMAND_BAN that can be used to manage
6252 the ban list of the channel. Updated the protocol specs.
6254 * Removed the channel modes: the SILC_CMODE_BAN and the
6255 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
6256 in the CMODE command. The equivalent features are now available
6257 using INVITE and BAN commands. Updated the protocol specs.
6259 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
6260 in the network about change in the current ban list. The notify
6261 type is not used by the client.
6263 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
6264 support the invite lists.
6266 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6268 * Added new function silc_string_regexify that converts string
6269 including wildcard characters into regex string that can
6270 be used by the GNU regex library. Added into the file
6271 lib/silcutil/silcutil.[ch].
6273 Added silc_string_regex_combine to combine to regex strings
6274 into one so that they can be used as one regex string by
6275 the GNU regex library. Added into the file
6276 lib/silcutil/silcutil.[ch].
6278 Added silc_string_regex_match to match two strings. It returns
6279 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
6281 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6283 * Imported GNU regex to the soruce tree into lib/contrib.
6284 Fixed some compiler warning from the regex.c.
6286 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6288 * Fixed MOTD command in the server to work in router environment.
6290 * Fixed the MOTD command in the client library to support
6291 the server argument in the command.
6293 * Added `nickname_len' argument to the silc_idlist_add_client
6294 in the server, as the `nickname' argument may be binary data
6297 * Added silc_idlist_get_channels to return all channels from
6300 * Implemented LIST command to the server. Affected file is
6303 * Implemented the LIST command to the client library and on the
6306 * Added [<user count>] argument to the LIST command reply.
6307 With private channels the user count is not shown.
6309 * Updated TODO and README.
6311 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6313 * The client entry's data.registered must be TRUE even with
6314 global client entry on global client list. The data.registered
6315 is used to check whether the client is anymore in the network,
6316 for example with WHOWAS command so it must be valid.
6318 * Fixed the WHOWAS command in the server. It now actually works
6319 in router environment. Added function into silcd/command_reply.c
6320 silc_server_command_reply_whowas_save.
6322 * Added silc_idlist_purge function to the silcd/idlist.c
6323 to periodically purge the ID Cache.
6325 * Fixed INFO command in the server. It works now in router
6326 environment. Added <server name> argument to the INFO command
6327 reply. Updated the protocol specs.
6329 * Fixed minor bug in silc_idcache_purge to not purge if the
6330 expire value is zero.
6332 * Fixed various bugs in WHOIS and IDENTIFY command handling as
6333 they were buggy because of the WHOWAS information.
6335 * Fixed local command MSG to handle the async resolving of
6336 the remote client properly. It used to fail the first MSG.
6337 Affected file silc/local_command.c.
6339 * Added `data_len' field to SilcIDCache context.
6341 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6343 * Update TODO. Todo in commands in the server.
6345 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6347 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
6348 used by routers as broadcast packet to inform other routers
6349 about the changed user mode.
6351 Implemented the notify handling in the server. Affected file is
6352 silcd/packet_receive.c. Added the function
6353 silc_server_send_notify_umode to the silcd/packet_send.[ch].
6355 * Added new generic Channel Payload and deprecated the New Channel
6356 Payload. The New Channel Payload is now the generic Channel
6359 * Added new argument `mode' to the silc_server_send_new_channel
6360 as it is required in the Channel Payload now.
6362 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
6363 and created a new and real SilChannelPayload to represent the
6364 new generic Channel Payload. Implemented the encode/decode
6365 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
6367 * Added silc_server_get_client_channel_list to return the list
6368 of channels the client has joined for WHOIS command reply.
6369 Affected file silcd/server.[ch].
6371 * Implemented the channel list sending in the WHOIS command reply
6372 in server and in the client.
6374 Implemented the channel list displaying on the user interface
6375 as well. Affected file silc/client_ops.c.
6377 * Added silc_channel_payload_parse_list to parse list of Channel
6378 Payloads. It returns SilcDList list of SilcChannelPayloads.
6379 Client for example can use this function to parse the list of
6380 channels it receives in the WHOIS command reply. The caller
6381 must free the list by calling silc_channel_payload_list_free.
6382 Affected files lib/silccore/silcchannel.[ch].
6384 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6386 * Added one new argument <user mode> to the WHOIS command reply
6387 to return the mode of the user in SILC. Updated the protocol
6390 Implemented it to the server and client.
6392 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6394 * Fixed the mode printing on the user interface on joining.
6395 Affected file silc/client_ops.c.
6397 * Implemented the UMODE command and user modes in general to the
6398 client library and to the user interface.
6400 * Implemented the UMODE command to the server.
6402 * The server now sends UNKNOWN_COMMAND error status if client sends
6403 unknown command. Affected file silcd/command.c.
6405 * All server commands now handle the command identifier the right
6406 way when sending the command reply to the client. The client can
6407 use to identify the command replies with the identifier.
6409 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6411 * Added silc_server_get_client_route to resolve the route to
6412 the client indicated by the client ID. Affected file is
6415 * Added silc_server_relay_packet as general function to relay
6416 packet to arbitrary destination. This deprecates functions
6417 like _send_private_message_key, _relay_notify etc. Affected
6418 file is silcd/packet_send.[ch].
6420 Removed silc_server_send_key_agreement,
6421 silc_server_send_private_message_key and
6422 silc_server_packet_relay_notify functions from the file
6423 silcd/packet_send.[ch].
6427 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
6428 server. Affected file silcd/packet_receive.[ch].
6430 * Implemented the KILL command to the client. Implemented the
6431 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
6432 Affected files lib/silcclient/command[_reply].c and
6433 lib/silcclient/client_notify.c. Implemented the KILL notify
6434 printing in the user inteface.
6436 * Fixed a lot silc_parse_nick memory leaks from the client
6437 library in the file lib/silcclient/command.c.
6439 * Changed the silc_server_send_notify_on_channels's `sender'
6440 argument from SilcSocketConnection to SilcClientEntry to
6441 check the sender as entry and not as connection object and not
6442 to send to the client provided as argument. The affected file
6443 is silcd/packet_send.[ch].
6445 * The notify packets that are destined directly to the client used
6446 to not to be processed by the server. Now changed that and the
6447 server processes all notify packets. After relaying the packet
6448 to the client the notify packet is processed in the server.
6450 * The silc_server_free_client_data now checks whether there is
6451 pending outgoing traffic for the client and purges the data to
6452 the network before removing the client entry.
6454 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6456 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
6457 an client is killed from the SILC Network. Updated the protocol
6460 Added new function silc_server_send_notify_killed to the
6461 silcd/packet_send.[ch].
6463 * Added function silc_server_packet_relay_notify to relay notify
6464 packets that are destined directly to a client. In this case
6465 the server does not process the notify packets but merely relays
6466 it to the client. Affected file silcd/packet_send.[ch].
6468 Added also silc_server_packet_process_relay_notify to check
6469 whereto relay the notify. Affected file is
6470 silcd/packet_receive.[ch].
6472 * Implemented the KILL command to the server.
6476 * Added the backup schema desgined last fall to the protocol
6477 specs for everyone to see. The specification is in the
6478 *-spec-xx.txt draft and the packet type definitions for the
6479 backup routers is in *-pp-xx.txt draft. Thusly, added also
6480 new packet type SILC_PACKET_CELL_ROUTERS.
6482 * A big security problem in the implementation discovered. The
6483 signoff of an client did not cause new channel key generation
6484 which it of course should've done. The channel keys must be
6485 always re-generated when client leaves (or signoffs) the channel.
6486 The silc_server_remove_from_channels funtion now handles
6487 the channel key re-generation.
6489 * Added `sender' argument to the silc_server_send_notify_on_channels
6490 to not to send the client provided as argument. Affected file
6491 silcd/packet_send.[ch].
6493 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6495 * Implemented OPER and SILCOPER commands into the server and
6498 * Added silc_auth_verify and silc_auth_verify_data to verify
6499 the authentication directly from the authentication payload.
6500 It supports verifying both passphrase and public key based
6501 authentication. Affected file lib/silccore/silcauth.[ch].
6503 * Added `hash' field to the SilcIDListData structure. It is the
6504 hash negotiated in the SKE protocol. Affected file is
6507 * Slight redesigning of the SilcAuthPayload handling routines.
6508 Do not send SilcPKCS but SilcPublicKey as argument.
6510 * Implemented the public key authentication support to the
6511 serverconfig. The public key is loaded from the provided path
6512 and saved as authentication data to void * pointer. Thus,
6513 changed the unsigned char *auth_data to void *auth_data;
6515 * Fixed SHUTDOWN command to send the reply before the server
6516 is shutdown. :) Affected file silcd/command.c.
6518 * Fixed fatal bug in CONNECT command. The hostname was invalid
6519 memory and server crashed. Affected file silcd/command.c.
6521 * Fixed fatal bug in CLOSE command. The server_entry became
6522 invalid but was referenced later in the command. Affected file
6525 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6527 * Fixed fatal bug in failure packet handling. Server ignored
6528 the failure and thus crashed when it came.
6532 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6534 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
6535 that the command may be executed only once in (about) 2 seconds.
6536 The old SILC_CF_LAG flag is same but allows command bursts up
6537 to five before limiting.
6539 Added the support for CF_LAG and CF_LAG_STRICT flags to the
6540 server code. Various commands now includes the CF_LAG_STRICT
6541 flag to disallow any kind of miss-use of the command.
6543 * Fixed the silc_buffer_unformat to not to allocate any data
6544 if the length of the data is zero. It used to allocate the
6545 length + 1. Affected file lib/silcutil/silcbuffmt.c.
6547 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6549 * Changed the format of AdminConnection configuration section
6550 in the server. Added username of the admin to the format.
6551 Affected files silcd/serverconfig.[ch].
6553 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
6554 to return admin configuration data by host, username and/or
6557 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6559 * Implemented WHOWAS command to the server. Added the functions:
6561 silc_server_command_whowas_parse,
6562 silc_server_command_whowas_send_reply,
6563 silc_server_command_whowas_from_client and
6564 silc_server_command_whowas_from_server
6566 * Added <Client ID> argument to the WHOWAS command reply. Updated
6567 the protocol specs accordingly.
6569 * Implemented WHOWAS command and command_reply to the client
6572 Implemented the WHOWAS printing on the user interface.
6574 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6576 * Added new argument to the WHOWAS command reply, the real name.
6577 It is an optional argument. Updated the protocol specs.
6579 * Added SilcIDCacheDestructor callback that is registered when
6580 the SilcIDCache is allocated. The callback is called when
6581 an cache entry in the ID Cache expires, or is purged from the
6582 cache. Added into lib/silccore/idcache.[ch].
6584 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
6585 to destruct the client entries when the cache entry expires.
6586 Other ID Cache's in server and in the client library ignores
6589 * If the ID Cache entry's `expire' field is zero then the entry
6590 never expires. Added boolean `expire' argument to the
6591 silc_idcache_add function in the lib/silccore/idcache.[ch].
6592 If it is TRUE the default expiry value is used.
6594 * Added silc_server_free_client_data_timeout that is registered
6595 when client disconnects. By default for 5 minutes we preserve
6596 the client entry for history - for WHOWAS command.
6598 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6600 * Added support to the server to enforce that commands are not
6601 executed more than once in 2 seconds. If server receives
6602 commands from client more frequently, timeout is registered
6603 to process the commands. Affected file silcd/command.c.
6604 Added new function silc_server_command_process_timeout.
6606 * Changed NICK_NOTIFY handling in client library to check that
6607 if the client's nickname was changed, so there is no need to
6608 resolve anything from the server.
6610 * Removed error printing from the WHOIS and IDENTIFY commands.
6611 If error occurs then it is ignored silently in the client library.
6612 The application, however, may map the received error to
6613 human readable error string. The application currently maps
6614 the NO_SUCH_NICKNAME error to string.
6616 * Made the command status message public to the application. Moved
6617 them from lib/silcclient/command_reply.c to
6618 lib/silcclient/command_reply.h. The application can map the
6619 received command status to the string with the
6620 silc_client_command_status_message function.
6622 * Added check to the server to check that client's ID is same
6623 as the Source ID in the packet the client sent. They must
6626 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6628 * Added dist-bzip hook to the Makefile.am to make bzip2
6629 compressed distributions.
6631 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6633 * Server now enforces the maximum length for the nickname and
6634 the channel as protocol specification dictates. 128 bytes for
6635 nickname and 256 bytes for channel name.
6637 * Moved the WHOIS printing to the application. The client libary
6638 does not print out the WHOIS information anymore, the application
6639 must do it. Renamed silc_client_command_reply_whois_print to
6640 the silc_client_command_reply_whois_save.
6642 The client's idle time is also sent to the application now, and
6643 the idle is shown on screen.
6645 * Added silc_client_command_reply_identify_save to save the
6646 received IDENTIFY entries.
6648 * Do not check for channel private keys in message sending and
6649 reception if the channel does not have the PRIVKEY mode set.
6650 Affected file lib/silclient/client_channel.c.
6652 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6654 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
6655 just surfaced after chaning the JOIN procedure.
6657 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6659 * Added silc_client_get_clients_by_list to get client entries
6660 from Client ID list, that is returned for example by JOIN
6661 and USERS command replies. The application should use this
6662 function for example when JOIN command reply is received to
6663 resolve the clients already on the channel (library does not
6664 do that anymore as USERS command reply is not used in the JOIN
6665 procedure anymore). Affected files lib/silcclient/silcapi.h and
6666 lib/silcclient/idlist.c.
6668 * JOIN command reply and USERS command reply returns now SilcBuffer
6669 pointers instead of unsigned char pointers when returning
6670 the client list and mode list.
6672 * Added <Client ID> argument to the JOIN command reply, mainly
6673 for the server to identify for which client the command was
6674 originally sent. Updated protocol specs accordingly.
6676 * Added SilcDlist private_key pointer to the SilcChannelEntry
6677 in the client to support the channel private keys. Affected
6678 file is lib/silcclient/idlist.h.
6680 * Added SilcChannelPrivateKey argument to the function
6681 silc_client_send_channel_message so that application can choose
6682 to use specific private ke if it wants to. If it is not provided,
6683 the normal channel key is used, unless private keys are set.
6684 In this case the first (key that was added first) is used
6685 as the encryption key.
6687 * Implemented the support for channel private key handling.
6688 Implemented the following functions:
6690 silc_client_add_channel_private_key,
6691 silc_client_del_channel_private_keys,
6692 silc_client_del_channel_private_key,
6693 silc_client_list_channel_private_keys and
6694 silc_client_free_channel_private_keys
6696 Affected file lib/silcclient/client_channel.c.
6698 * Added the support for the private keys in the channel message
6699 sending and encryption and in the message reception and
6700 decryption. Affected funtions are
6701 silc_client_send_channel_message and silc_client_channel_message.
6703 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6705 * Added SKE's key verify callback to the client library's
6706 KE protocol context. Affected files lib/silcclient/protocol.[ch].
6708 * Removed the statement that server (or router) must send USERS
6709 command reply when joining to the channel so that the client
6710 knows who are on the channel. Instead, the client list and
6711 client's mode list is now sent in the JOIN command reply to the
6712 client who joined channel. This is better solution.
6714 * Added function silc_server_get_users_on_channel and function
6715 silc_server_save_users_on_channel to the silcd/server.[ch].
6717 * Removed function silc_server_command_send_users from the
6720 * Do not show topic on the client library anymore. The topic is
6721 sent in the command reply notify to the application and the
6722 application must show the topic now.
6724 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6726 * Added client searching by nickname hash into the IDENTIFY and
6727 WHOIS commands in the server as they were clearly missing from
6728 them. Affected file is silcd/command.c.
6730 * Fixed a bug in private message receiving in the client library.
6731 The remote ID was freed and it wasn't supposed, now it is
6734 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6736 * Minor fix to the channel payload; allocate the data area, as it
6737 needs to be of specific length.
6739 * If the key agreement port is zero then the operating
6740 system will define the bound port. Affected files are
6741 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
6743 * Added new function silc_channel_payload_decrypt into the file
6744 lib/silccore/silcchannel.[ch].
6746 * Moved the channel message etc, check from silc_packet_decrypt
6747 to applications. The library calls now a generic
6748 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
6749 when the packet is either normal or special. This was done to
6750 allow more wide range of checking that was not allowed when
6751 the code was in library. Now applications can do virtually any
6752 checks to the packet and return to the library the decision how
6753 the packet should be processed. Affected files are
6754 lib/silccore/silcpacket.[ch].
6756 Added silc_server_packet_decrypt_check to the server and
6757 silc_client_packet_decrypt_check to the client library.
6759 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
6760 to send with specified source and destination information.
6762 * Channel message delivery between routers was broken after the
6763 channel key distribution was fixed earlier. The channel key
6764 was used be to distributed to other routers as well which is not
6765 allowed by the protocol. Now this is fixed and channel keys
6766 really are cell specific and the channel message delivery between
6767 routers comply with the protocol specification.
6769 * Fixed various commands in server to check also the global list
6770 for the channel entry and not just the local list. The affected
6771 file silcd/command.c.
6773 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6775 * Added assert()s to buffer formatting and unformatting routines
6776 to assert (if --enable-debug) when error occurs. Affected
6777 file: lib/silcutil/silcbuffmt.c.
6779 * Changed to auto-reconnect to check whether the remote host is
6780 router and register the re-connect timeout if it is. It used
6781 to check that whether we are normal server, but router must do
6782 auto-reconnect with another router as well. Affected file
6785 * Removed the [<key len>] option from CMODE command as the cipher
6786 name decides the key length, nowadays. See the defined ciphers
6787 from the protocol specification.
6789 * Added [<hmac>] option to the CMODE command to define the HMAC
6790 for the channel. Added SILC_CMODE_HMAC channel mode.
6792 * Added [<hmac>] option for the JOIN command so that user can
6793 select which HMAC is used to compute the MACs of the channel
6796 * Added Hmac field to the Channel Message Payload. The integrity
6797 of plaintext channel messages are now protected by computing
6798 MAC of the message and attaching the MAC to the payload. The
6799 MAC is encrypted. Now, it is clear that this causes some
6800 overhead to the size of the packet but rationale for this is that
6801 now the receiver can verify whether the channel message decrypted
6802 correctly and also when private keys are set for the channel the
6803 receiver can decrypt the packet with several keys and check from
6804 the MAC which key decrypted the message correctly.
6806 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
6807 lib/silccrypt/silccipher.[ch].
6809 * Added silc_hash_len to return the digest length into the
6810 lib/silcrypt/silchash.[ch].
6812 * Rewrote parts of Silc Channel Payload interface in the
6813 lib/silccore/silcchannel.[ch]. The encode function now also
6814 encrypts the packet and parse function decrypts it.
6816 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6818 * Fixed a minor formatting bug in the SKE's key material processing.
6819 It actually might have processed the keys wrong way resulting
6822 * Redefined the mandatory HMAC algorithms and added new algorithms.
6823 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
6824 and hmac-md5 truncated to 96 bits. The mandatory is now
6825 hmac-sha1-96. Rest are optional (including the one that used
6826 to be mandatory). Rationale for this is that the truncated HMAC
6827 length is sufficient from security point of view and can actually
6828 make the attack against the HMAC harder. Also, the truncated
6829 HMAC causes less overhead to the packets. See the RFC2104 for
6832 * Added new [hmac] configuration section. The SKE used to use
6833 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
6834 is of course wrong. The official names that must be proposed in
6835 the SKE are the ones defined in the protocol specification
6836 (hmac-sha1-96 for example). The user can configure any hmac
6837 using any hash function configured in the [hash] section. At
6838 least, the mandatory must be configured.
6840 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
6842 * Added HMAC list to the SKE proposal list. It has now both
6843 hash algorithm list and HMAC list. This makes the protocol
6844 incompatible with previous versions. The SKE now seems to work
6845 the way it is supposed to work, for the first time actually.
6847 * Defined plain Hash algorithms to the protocol specification.
6850 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6852 * Implemented support for key agreement packets into the server.
6853 Added functions silc_server_key_agreement and
6854 silc_server_send_key_agreement. Other than these functions,
6855 server has nothing to do with this packet.
6857 * Added support for private message key packets into the server.
6858 Added functions silc_server_private_message_key and
6859 silc_server_send_private_message_key.
6863 * Changed the silc_[client|server]_protocol_ke_set_keys to be
6864 called in the protocol's final callback instead in the END
6865 protocol state. This makes a little more sense and in the same
6866 time in client we can use the same protocol routines for normal
6867 key exchange and to key agreement packet handling as well.
6869 * Added to both client's and server's KE protocol context the
6870 SilcSKEKeyMaterial pointer to save the key material. We will
6871 bring the key material to the protocol's final callback by doing
6872 this. The final callback must free the key material.
6874 * Added SKE's packet_send callback into client's KE protocol
6875 context so that the caller can choose what packet sending function
6876 is used. This way we can use different packet sending when
6877 doing normal SKE when doing key agreement packet handling (in
6878 the key agreement packet handling we do not want to encrypt
6881 * Implemented the responder side of the key agreement routines
6882 in the client. The client can now bind to specified port and
6883 accept incoming key negotiation. The key material is passed
6884 to the application after the protocol is over.
6886 * Implemented the processing of incoming Key Agreement packet
6887 in the client. Added function silc_client_key_agreement to
6890 * Implemented the intiator side of the key agreement routines
6891 in the client. The client can now initiate key agreement with
6892 another remote client. The key material is passed to the
6893 application after the protocol is over.
6895 * Created client_keyagr.c to include all the key agreement
6898 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
6899 SILC_TASK_CALLBACK except that it is not static.
6901 * Created client_notify.c and moved the Notify packet handling
6902 from the client.[ch] into that file.
6904 * Created client_prvmsg.c and moved all private message and
6905 private message key routines from the client.[ch] into that file.
6907 * Create client_channel.c and moved all channel message and
6908 channel private key routines from the client.[ch] into that file.
6910 * Changed silc_client_get_client_by_id_resolve to resolve with
6911 WHOIS command instead of IDENTIFY command, in the file
6912 lib/silclient/idlist.c.
6914 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6916 * Implemented the SKE's responder side to the Client library.
6918 * When FAILURE is received to the protocol do not trust it
6919 blindly. Register a timeout to wait whether the remote closes
6920 the connection as it should do it, only after that process the
6921 actual failure. This was changed to both client and server.
6923 * Added client_internal.h to include some of the structures
6924 there instead of client.h in lib/silcclient/.
6926 * Added function silc_task_unregister_by_callback to unregister
6927 timeouts by the callback function.
6929 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6931 * Some "Incomplete WHOIS info" errors has been appearing on the
6932 log files. Took away the entry->userinfo check from WHOIS
6933 reply sending. The entry->userinfo is now " " if client did not
6934 provide one. I thought this was fixed earlier but something
6935 is wrong still. Let's see if the error still appears.
6937 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6939 * Fixed a minor bug in the login when the channel key is
6940 re-generated in the server. It used to generate the key in
6941 wrong order and thus caused problems in the channel traffic.
6943 * Fixed a minor bug in channel key distsribution after
6944 KICK command. The key was not sent to the router even though
6947 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6949 * Added silc_ske_process_key_material_data as generic routine
6950 to process any key material as the SILC protocol dictates. The
6951 function is used by the actual SKE library but can be used by
6952 applications as well. This relates to the private message keys
6953 and the channel private keys since they must be processed the
6954 same way the normal SILC session keys. The protocol dictates
6955 this. Affected files: lib/silcske/silcske.[ch].
6957 Added also silc_ske_free_key_material to free the
6958 SilcSKEKeyMaterial structure.
6960 * Defined silc_cipher_set_key function to set the key for
6961 cipher without using the object's method function. The affected
6962 files: lib/silccrypt/silccipher.[ch].
6964 * Implemented silc silc_client_add_private_message_key,
6965 silc_client_add_private_message_key_ske,
6966 silc_client_del_private_message_key,
6967 silc_client_list_private_message_keys and
6968 silc_client_free_private_message_keys functions in the
6971 Added functions silc_client_send_private_message_key to send
6972 the Private Message Key payload and silc_client_private_message_key
6973 to handle incoming Private Message Key payload.
6975 * Added Cipher field to the Private Message Key payload to set
6976 the cipher to be used. If ignored, the default cipher defined
6977 in the SILC protocol (aes-256-cbc) is used.
6979 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6981 * Removed lib/silcclient/ops.h file.
6983 Redefined parts of the SILC Client Library API. Created new
6984 file silcapi.h that deprecates the ops.h file and defines the
6985 published Client Library API. Defined also private message key
6986 API and channel private key API into the file.
6988 This is the file that the application must include from the
6989 SILC Client Library. Other files need not be included by
6990 the application anymore.
6992 * Added new key_agreement client operation callback and also
6993 defined the Key Agreement library API for the application.
6995 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6997 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
6998 is used by clients to request key negotiation between another
6999 client in the SILC network. If the negotiation is started it
7000 is performed using the SKE protocol. The result of the
7001 negotiation, the secret key material, can be used for example
7002 as private message key.
7004 Implemented the Key Agreement payload into the files
7005 lib/silccore/silauth.[ch].
7007 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7009 * Redefined ciphers for the SILC protocol. Added some new ciphers
7010 and defined the key lengths for the algorithms. Changed the
7011 code accordingly. The default key length is now 256 bits.
7013 * Fixed SKE key distribution function silc_ske_process_key_material
7014 when the key length is more than 128 bits. The default key
7015 length in SILC is now 256 bits.
7017 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
7018 to indicate unsupported algorithm.
7020 * Renamed rijndael.c to aes.c and all functions as well.
7022 * Fixed a long standing channel key setting bug in client library.
7023 Weird that it has never surfaced before.
7025 * Fixed bug in channel deletion. If the entire channel is removed
7026 then it must also delete the references of the channel entry
7027 from the client's channel list as the client's channel entry and
7028 the channel's client entry share same memory.
7030 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7032 * Implemented CONNECT and SHUTDOWN commands in the client.
7034 * Implemented CLOSE command to the client.
7036 * Added the function silc_idlist_find_server_by_name into the
7037 files silcd/idlist.[ch].
7039 Added the function silc_idlist_find_server_by_conn into the
7040 files silcd/idlist.[ch].
7042 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7044 * DIE command was renamed to SHUTDOWN. Updated the both code
7047 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
7048 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
7050 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
7053 * Added function silc_server_create_connection function to create
7054 connection to remote router. My server implementation actually
7055 does not allow router to connect to normal server (it expects
7056 that normal server always initiates the connection to the router)
7057 so the CONNECT command is only good for connecting to another
7060 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7062 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
7063 or some other client was kicked from the channel.
7065 Implemented the handling of the notify type to both client
7068 Implemented silc_server_send_notify_kicked to send the KICKED
7069 notify. It is used to send it to the server's primary router.
7071 * Implemented the KICK command into server and client.
7073 * Added `query' argument to the silc_idlist_get_client function
7074 to indicate whether to query the client from server or not if
7077 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
7078 to indicate that the client is not channel founder.
7082 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7084 * Removed the rng context from SilcPacketContext structure and
7085 changed that the packet routine uses the Global RNG API.
7087 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7089 * Added support for quit message that client can "leave" on the
7090 channel when it quits the SILC. It is ditributed inside the
7091 SILC_NOTIFY_TYPE_SIGNOFF notify type.
7093 Added silc_server_free_client_data that will take the
7094 signoff message as argument.
7096 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
7098 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7100 * Updated parts of the protocol specification to keep it up
7103 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7105 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
7106 payloads in one packet.
7108 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
7109 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
7110 use now the new List flag.
7112 * Also deprecated the following packet types: REPLACE_ID,
7113 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
7115 * Added list support for Notify packet in server.
7117 * Added silc_server_send_notify_channel_change to send the
7118 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
7119 the silc_server_send_replace_id.
7121 * Added silc_server_send_notify_nick_change to send the
7122 NICK_CHANGE notify type. Deprecates the function
7123 silc_server_send_replace_id.
7125 * Added silc_server_send_notify_join to send the JOIN notify type.
7126 Deprecates the function silc_server_send_new_channel_user.
7128 * Added silc_server_send_notify_leave to send LEAVE notify type.
7129 Deprecates the function silc_server_send_remove_channel_user.
7131 * Added silc_server_send_notify_cmode and
7132 silc_server_send_notify_cumode to send CMODE and CUMODE notify
7133 types. Deprecates the silc_server_send_set_mode function.
7135 * Added SERVER_SIGNOFF notify type to indicate that server has
7136 quit. This means that all clients on the channel from that
7137 server will drop. This can be also used when netsplit happens.
7139 Deprecated REMOVE_ID packet type since it is not needed anymore
7142 Added silc_server_send_notify_server_signoff to send the
7143 SERVER_SIGNOFF notify type. Deprecates the function
7144 silc_server_send_remove_id.
7146 Added also silc_server_send_notify_signoff to send the
7147 SIGNOFF notify type.
7149 * Employed the PKCS #1. It is the mandatory way to do RSA in the
7150 SILC protocol from this day on. Changed the protocol
7151 specification as well.
7153 * Added silc_server_send_notify_topic_set to send TOPIC_SET
7154 notify type. It is used between routers to notify about
7155 topic changes on a channel.
7157 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
7160 * Partly updated the protocol specification to comply with the
7161 changes now made. It is still though a bit outdated.
7163 * The JOIN notify type now takes one extra argument <Channel ID>.
7164 The packet used to be destined to the channel but now the
7165 JOIN type may be sent as list thus it is impossible to
7166 destine it to any specific channel. By adding this argument
7167 it is again possible.
7169 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7171 * Added CREDITS file. The CHANGES and CREDITS file will appear
7172 in the distribution as well.
7174 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7176 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
7177 types in the server's silcd/packet_receive.c.
7179 * Implemented CMODE and CUMODE to work in router environment.
7181 * Fixed minor encoding and decoding buglet from the
7182 lib/silccore/silcmode.c.
7184 * Fixed buffer overflow from lib/silcclient/command.c in USERS
7187 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
7189 * Changed all SilcConfigServer* and silc_config_server* to
7190 SilcServerConfig* and silc_server_config*, respectively.
7193 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7195 * Associated the ID (client or server ID) to the Authentication
7196 Payload to avoid any possibility of forging. Updated the
7197 protocol specification and the code accordingly.
7199 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7201 * The RSA key length is now save to the RsaKey context in the
7202 key generation process in lib/silccrypt/rsa.c. The key length
7203 is now used to figure out the maximum size of the block allowed
7204 to be encrypted/signed.
7206 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
7207 is equivalent to the silc_mp_mp2bin but does not allocate any
7210 * Changed silc_mp_mp2bin API to take length argument. If it is
7211 non-zero then the buffer is allocated that large. If zero, then
7212 the size is approximated using silc_mp_sizeinbase, which however
7215 * Created Global RNG API which is global RNG that application can
7216 initialize. After initializing, any routine anywhere in the
7217 code (including library) can use RNG without allocating a new
7218 RNG object. This was done to allow this sort of use of the
7219 RNG in code that has no chance to allocate RNG object. All
7220 applications currently allocate this and many routines in the
7221 library use this. Affected file lib/silccrypt/silcrng.[ch].
7223 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
7224 it to use the Global RNG API.
7226 * Defined Authentication Payload into protocol specification that
7227 is used during SILC session to authenticate entities. It is
7228 used for example by client to authenticate itself to the server
7229 to obtain server operator privileges.
7231 Implemented this payload into the lib/silccore/silcauth.[ch].
7232 Implemented also routines for public key based authentication
7233 as the new protocol specification dictates.
7235 Moved definitions of different authentication methods from
7236 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
7238 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
7239 silc_pkcs_verify and silc_pkcs_sign_with_hash and
7240 silc_pkcs_verify_with_hash functions into the file
7241 lib/silccrypt/silcpkcs.[ch].
7243 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7245 * The client entry's userinfo pointer must be always valid.
7246 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
7247 will fail since it requires the userinfo. Now, the userinfo
7248 is allocated as "" if actual userinfo does not exist. Actually,
7249 it must exist and it is totally Ok to drop client connections
7250 that does not announce the userinfo. However, we will make
7251 this workaround for now.
7253 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
7254 to return the remote port by socket.
7256 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7258 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
7259 SILC_SERVER_PENDING_EXEC and added an new macro
7260 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
7261 data or when error occurs while processing the pending command.
7263 Added new argument `destructor' into silc_server_command_pending
7264 and to the SilcServerCommandPending object. This destructor is
7265 now called after calling the pending callback or if error occurs
7266 immediately. If error occurs the actual pending callback won't
7267 be called at all - only the destructor. The destructor may be
7268 NULL if destructor is not needed.
7270 All this applies for client library code as well. Similar
7271 changes were made there as well for the pending commands.
7273 In the client, the application must now allocate the
7274 SilcClientCommandContext with the silc_client_command_alloc
7277 * Added reference counter to the SilcServerCommandContext. Added
7278 function silc_server_command_alloc and silc_server_command_dup
7281 Same type of functions added to the client library for the same
7284 * Removed the cmd_ident from IDListData away since it is now
7285 global for all connections. It is the command identifier used
7286 in command sending and with pending commands. The affected file
7289 * Added reference counter to the SilcSocketConnection objecet to
7290 indicate the usage count of the object. The object won't be
7291 freed untill the reference counter hits zero. Currently only
7292 server uses this, and client ignores it. The client must be
7293 set to use this too later. The affected files are
7294 lib/silccore/silcsockconn.[ch]. Added also the function
7295 silc_socket_dup to increase the reference counter.
7297 This was mainly added because it is possible that the socket
7298 is removed underneath of pending command or other async
7299 operation. Now it won't be free'd and proper DISCONNECTING
7300 flags, etc. can be set to avoid sending data to connection that
7301 is not valid anymore.
7303 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
7304 the connection. After that it sets SILC_SET_DISCONNECTED.
7305 It is, however, possible that the socket data is not still freed.
7306 The silc_server_packet_process now checks that data is not
7307 read or written to connection that is DISCONNECTED. The socket
7308 get's freed when the reference counter hits zero.
7310 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7312 * Changed the client operation API: channel_message operation's
7313 `sender' is now the client entry of the sender, not the nickname
7314 and the `channel' is the channel entry, not the channel name.
7316 In the private_message operation the `sender' is now also the
7317 client entry of the sender not the nickname.
7319 Affected file is lib/silcclient/ops.h and all applications
7320 using the client operations.
7322 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7324 * Moved the calling of ops->connect() from connect_to_server_final
7325 into receive_new_id functin since that is the point when the
7326 client is actually allowed to send traffic to network. The
7327 affected file is lib/silcclient/client.c.
7329 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7331 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
7332 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
7333 (if needs broadcasting) instead of broadcasting the packets one
7334 by one which would make a burst in the network traffic.
7336 * Added `broadcast' argument to the functions in silcd/server.[ch]
7337 silc_server_create_new_channel[_with_id] to indicate whether
7338 to send New Channel packet to primary router.
7340 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7342 * Added new function into the silcd/server.[ch] files:
7343 silc_server_create_new_channel_with_id to create new channel with
7344 already existing Channel ID.
7346 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
7347 lib/silccore/silcpacket.h. This packet is used t send list of
7348 Set Mode payloads inside one packet. Server uses this to set
7349 the modes for the channels and clients on those channels, that it
7350 announced to the router when it connected to it. The protocol
7351 specification has been updated accordingly.
7353 * The silc_server_new_channel did not handle the packet coming
7354 from normal server as it normally does not send that. However,
7355 when it announces its channels it does send it. Implemented
7356 the support for that.
7358 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
7359 into the file lib/silccore/id.h.
7361 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7363 * Fixed memory leaks in the functions silc_idlist_del_client,
7364 silc_idlist_del_channel and silc_idlist_del_server in the file
7365 silcd/idlist.c. All of those leaked like a sieve.
7367 * Fixed some small memory leaks in the client's function
7368 silc_client_notify_by_server.
7370 * Added functions into silcd/server.c: silc_server_announce_clients,
7371 silc_server_announce_channels and silc_server_announce_server.
7372 These functions are used by normal and router server to announce
7373 to its primary router about clients, channels and servers (when
7374 router) that we own. This is done after we've connected to the
7377 These functions effectively implements the following packet types:
7378 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
7379 and SILC_PACKET_NEW_ID_LIST.
7381 * Added new functions into the silcd/packet_receive.[ch]:
7382 silc_server_new_id_list, silc_server_new_channel_list and
7383 silc_server_new_channel_user_list to handle the incoming
7384 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
7386 * Added support of changing Channel ID in the function
7387 silc_server_replace_id. If the server that announces a channel
7388 to the router already exists in the router (with same name but
7389 with different Channel ID), router is responsible to send
7390 Replace ID packet to the server and force the server to change
7391 the Channel ID to the one router has.
7393 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
7394 client that the Channel ID has been changed by the router. The
7395 normal server sends this to the client. Client must start using
7396 the new Channel ID as the channel's ID.
7398 Implemented handling of this new type into lib/silcclient/client.c
7399 into the function silc_client_notify_by_server.
7401 * Added new function silc_idlist_replace_channel_id into the files
7402 silcd/idlist.[ch] to replace the Channel ID.
7404 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7406 * Call silc_server_command_identify_check always when processing
7407 the IDENTIFY command in silcd/command.c
7409 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7411 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
7412 send keepalive packets. The packet can be sent by clients,
7413 servers and routers.
7415 Added function silc_socket_set_heartbeat into the file
7416 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
7417 If not set, the heartbeat is not performed. The actual
7418 heartbeat is implemented in the low level socket connection
7419 library. However, application is responsible of actually
7422 Added silc_server_send_heartbeat to send the actual heartbeat
7423 packet into silcd/packet_send.[ch]. Server now performs
7424 keepalive with all connections.
7426 * Added silc_task_get_first function into lib/silcutil/silctask.c
7427 to return the timeout task with shortest timeout. There was a bug
7428 in task unregistration that caused problems. TODO has been
7429 updated to include that task system must be rewritten.
7431 * The client library will now resolve the client information when
7432 receiving JOIN notify from server for client that we know but
7433 have incomplete information.
7435 * Rewrote parts of silc_server_remove_from_channels and
7436 silc_server_remove_from_one_channel as they did not remove the
7437 channel in some circumstances even though they should've.
7439 * Encryption problem encountered in server:
7441 The LEAVE command used to send the Channel Key packet to the
7442 router immediately after generating it. However, the code
7443 had earlier sent Remove Channel user packet but not immediately,
7444 ie. it was put to queue. The order of packets in the router
7445 was that Channel Key packet was first and Remove Channel User
7446 packet was second, even though they were encrypted in the
7447 reverse order. For this reason, MAC check failed. Now, this
7448 is fixed by not sending the Channel Key packet immediately but
7449 putting it to queue. However, this is more fundamental problem:
7450 packets that are in queue should actually not be encrypted
7451 because packets that are sent immediately gets encrypted
7452 actually with wrong IV (and thus MAC check fails). So, packets
7453 that are in queue should be encrypted when they are sent to
7454 the wire and not when they put to the queue.
7456 However, the problem is that the current system has not been
7457 designed to work that way. Instead, the packet is encrypted
7458 as soon as possible and left to the queue. The queue is then
7459 just purged into wire. There won't be any fixes for this
7460 any time soon. So, the current semantic for packet sending
7463 o If you send packet to remote host and do not force the send
7464 (the packet will be in queue) then all subsequent packets to the
7465 same remote host must also be put to the queue. Only after the
7466 queue has been purged is it safe again to force the packet
7469 o If you send all packets immediately then it safe to send
7470 any of subsequent packets through the queue, however, after
7471 the first packet is put to queue then any subsequent packets
7472 must also be put to the queue.
7474 Follow these rules and everything works fine.
7476 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7478 * Added new function silc_server_remove_clients_by_server to
7479 remove all client entries from ID list when the server connection
7480 is lost. In this case it is also important to invalidate all
7481 client entires as they hold the invalid server entry. This
7482 fixes fatal bug when server has lost connection and will reconnect
7485 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7487 * Made some sanity checks to silc_server_daemonise like to check
7488 whether the requested user and group actually exists.
7490 * Added sanity check to SKE's silc_ske_responder_finish to check
7491 that the public and private key actually is valid.
7493 * Invalidate the client's nickname when receiving Replace ID
7494 packet and the Client ID is being replaced. This means that the
7495 server will query the nickname if someone needs it (client)
7498 * Sort the ID Cache in client library when the ID Cache data
7499 has changed (needs sorting).
7501 * Do not allow for SILC client to create several connections to
7502 several servers. The client does not support windows right now
7503 and generating multiple connections causes weird behaviour.
7505 Irssi-silc client does support windows and can handle several
7506 connections without problems, see: www.irssi.org and SILC plugin.
7508 * Fixed some places where client was added to the IDList. The
7509 rule of thumb is following (in order to get everything right):
7510 If the client is directly connected local client then the
7511 `connection' argument must be set and `router' argument must be
7512 NULL to silc_idlist_add_client function. If the client is not
7513 directly connected client then the `router' argument must
7514 bet set and the `connection' argument must be NULL to the
7515 silc_idlist_add_client function.
7517 * The funtion silc_server_packet_send_local_channel actually did
7518 not check whether the client was locally connected or not. It
7519 does that now. Fixed a bug related to LEAVE command.
7521 * Fixed Remove Channel User payload parsing bug in server's
7522 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
7524 * The server's silc_server_save_channel_key now checks also the
7525 global ID list for the channel as it might not be in the local
7526 list. Fixed a bug related to LEAVE command.
7528 * Is this the end of the [<unknown>] buglet that has been lurking
7529 around for a long time? A little for loop fix in server's
7530 silc_server_command_whois_parse that is used by both IDENTIFY
7531 and WHOIS command. At least, this was a clear bug and a cause
7532 of one type of [<unknown>] buglet.
7534 * WHOIS and IDENTIFY commands call the function
7535 silc_server_command_[whois/identify]_check function even if
7536 we are not router server.
7538 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7540 * Added --with-gmp configuration option. If set the GMP
7541 is always compiled in the SILC source tree. If not set then
7542 it is checked whether the system has the GMP3 installed. If
7543 it has then the GMP won't be compiled (the system's headers
7544 and library is used), if it doesn't have it then the GMP is
7545 compiled in the SILC source tree.
7547 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7549 * Changed RSA private exponent generation to what PKCS #1
7550 suggests. We try to find the smallest possible d by doing
7551 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
7552 not security fix but optimization.
7554 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7556 * Added new config entry [Identity] to fork the server and run
7557 it as specific user and group. A patch from Bostik.
7559 * Imported Dotconf configuration library into lib/dotconf.
7560 This will be used to create the SILC configuration files later.
7561 It will appear in the distsribution after this commit.
7563 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7565 * A big code auditing weekend happening. Auditing code for
7566 obvious mistakes, bugs and errors. Also, removing any code
7569 Removed files for being obsolete:
7571 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
7572 inline in the file lib/silcutil/silcbuffer.h)
7574 o lib/silcutil/silcbufutil.c (the header has inline versions)
7576 Changed code to fix possible error conditions:
7578 o The buffer formatting routines now check that the destination
7579 buffer really has enough space to add the data. This applies for
7580 both buffer formatting and unformatting
7581 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
7582 unformatting was changed to accomodate following rules:
7583 XXX_*STRING_ALLOC will allocate space for the data into the pointer
7584 sent to the function while XXX_*STRING will not allocate or copy
7585 the data into the buffer. Instead it sets the pointer from the
7586 buffer into the pointer sent as argument (XXX_*STRING used to
7587 require that the pointer must be allocated already). This change
7588 makes this whole thing a bit more consistent and more optimized
7589 (note that the data returned in the unformatting with XXX_*STRING
7590 must not be freed now). The routines return now -1 on error.
7592 o Tried to find all code that use buffer_format and buffer_unformat
7593 and added return value checking to prevent formatting and
7594 especially unformatting errors and possible subsequent fatal
7597 o Changed ske->x and ske->KEY to mallocated pointers in
7598 lib/silcske/silcske.h. Fixed possible data and memory leak.
7600 o Added return value checking to all *_parse* functions. Fixed
7601 many memory leaks as well.
7603 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
7604 so that buffer overflows would not happen. All code now also
7605 checks the return value as it can fail.
7607 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7609 * Added reconnection support to server if the normal server looses
7610 its connection to the router (for example if router is rebooted).
7611 The server performs normal reconnection strategy implemented
7612 to the server. Affected file silcd/server.c.
7614 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7616 * Added new packet type SILC_PACKET_SET_MODE that is used to
7617 distribute the information about changed modes (for clients,
7618 channels and clients channel modes) to all routers in the
7619 network. Updated the protocol specification accordingly.
7621 Added functions into silcd/packet_send.c and
7622 silcd/packet_receive.c: silc_server_send_set_mode,
7623 silc_server_set_mode.
7625 Added new files silcmode.[ch] into lib/silccore that implements
7626 the encoding and decoding of Set Mode Payload. Added new type
7627 SilcSetModePayload. Moved the definitions of different modes
7628 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
7630 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7632 * Oops, a little mistake in server's connection authentication
7633 protocol. The protocol is not ended with FAILURE but with
7634 SUCCESS if the authentication is Ok. :) Affected file is
7637 * Implemented NICK_CHANGE notify handling in server in the file
7638 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
7639 the local clients on the channel. After the changing nickname
7640 in router environment snhould work and the [<unknown>] nickname
7641 should appear no more.
7643 The silc_server_replace_id function that receives the Replace ID
7644 payload now sends the NICK_CHANGE notify type also in the file
7645 silcd/packet_receive.c
7647 * Changed WHOIS and IDENTIFY command to support the maximum amount
7648 of arguments defined in protocol specs (3328 arguments). This
7649 fixed a bug that caused problems when there were more than three
7652 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7654 * Added extra parameter, command identifier, to the
7655 silc_client_send_command so that explicit command identifier
7658 Changed that ID list routines uses specific command identifier
7659 when sending WHOIS/IDENTIFY requests to the server so that they
7660 can be identified when the reply comes back.
7662 Affected files lib/silcclient/command.[ch],
7663 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
7665 * Added `sender' argument to silc_server_packet_send_to_channel
7666 to indicaet the sender who originally sent the packet to us
7667 that we are now re-sending. Ignored if NULL. Affected file
7668 silcd/packet_send.[ch].
7670 * Added some server statistics support in silcd/server_internal.h
7671 SilcServerStatistics structure and around the server code. Also
7672 send some nice statistics information when client is connecting
7675 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7677 * Fixed channel ID decoding in server's JOIN command reply in
7678 silcd/command_reply.c
7680 * Fixed braodcasting of replace ID payload to not to send it if
7681 we are standalone server in silcd/packet_receive.c.
7683 * Fixed all channel message sending routines to not to send
7684 packets to clients that has router set, since they are routed
7685 separately in the same function earlier. Affects file
7686 silcd/packet_send.c and all channel packet sending functions.
7688 * In USERS reply, res_argv[i] are not allocated, the table
7689 is allocated. Thus changed that free the table, not its
7692 * In server's whois_check and identify_check if the client is
7693 locally connected do not send any WHOIS commands - they are not
7696 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7698 * Fixed some minor bugs in client when sending WHOIS command. The
7699 arguments was in wrong order.
7701 * Removed statis function add_to_channel from server in
7702 silcd/command.c that was previously used with the joining but
7705 * Tested USERS command in router environment successfully with two
7706 routers, two servers and two clients.
7708 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7710 * Reorganized the USERS command and command reply in client library
7711 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
7712 When the command is given by user we register a pending command
7713 callback that will reprocess the command after the reply has been
7714 received from the server. When reprocessing the packet we then
7715 display the information. Thus, the USERS information is displayed
7716 now in the command callback instead of in the command reply
7717 callback. The processing of the command is same as previously
7718 when server has sent the command reply in the JOINing process.
7720 * Added to USERS command in silcd/command_reply.c to join the client,
7721 we didn't use to know about, to the channel after we've created
7722 a client entry for it. Also, for clienet we did know already still
7723 check whether it is on the channel or not and add it if not.
7725 * Removed silc_server_command_join_notify as the function and its
7728 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7730 * Changed the client's pending command handling to the same as the
7731 server's pending command handling. It is also now possible to
7732 execute command reply functions from other command reply
7733 function as the function callbacks for commands and command
7734 replies are one and same. The pending commands are not static
7735 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
7736 in client connection context. Thus, pending commands are server
7737 connection specific as it is convenient.
7739 Changed the function silc_client_command_pending and
7740 silc_client_command_pending_del and added new function
7741 silc_client_command_pending_check. Removed the
7742 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
7745 * Added cmd_ident, current command identifier, to the client
7746 connection context in lib/silcclient/client.h to keep track on
7747 command identifiers used in command sending. Client's command reply
7748 function handling now supports the mandatory command identifiers.
7750 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
7751 funtions in client to fully support pending command callbacks.
7753 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
7754 as one of the arguments to the application in the command reply
7757 * NOTE: The FORWARDED flag is depracated. It used to be depracated
7758 before first releasing SILC but came back. Now it is removed again
7759 and should come back nomore. The FORWARDED flag was used only
7760 by the JOINing procedure by forwarding the command packet to router.
7761 Now, the JOINing procedure has been changed to more generic (due
7762 to various router environment issues) and FORWARDED is not needed
7763 anymore for anything. The protocol specification is yet to be
7766 Now, removed silc_server_packet_forward from server and the flag
7767 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
7769 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7771 * Renamed NAMES command to USERS command. The NAMES was named that
7772 due to historical reasons. Now it is renamed. Also, rewrote
7773 parts of the USERS command. The nickname list is not sent anymore
7774 by the server. Only Client ID and mode lists are sent in the USERS
7775 command. Changed this also to the protocol specification.
7777 The client now resolves the names and stuff after it receives
7778 the USERS list from the server when joining to the channel.
7780 * WHOIS and IDENTIFY commands has been changed to support multiple
7781 Client ID's per command. One can now search for multiple users
7782 in the network by sending only one WHOIS or IDENTIFY command.
7783 Changed the code and the protocol specifications.
7785 * Removed silc_server_command_identify_parse and changed that IDENTIFY
7786 uses silc_server_command_whois_parse to parse the request. */
7788 * If normal server, do not parse the WHOIS and IDENTIFY requests
7789 before sending it to the router. Saves some time.
7791 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7793 * Fixed JOIN command on client library. Wrong number of arguments
7794 used to crash the client.
7796 * Added silc_server_channel_has_global function to check whether
7797 channel has global users or not.
7799 * Added silc_server_channel_has_local function to check whether channel
7800 has locally connected clients on the channel.
7802 * The silc_server_remove_from_one_channel now checks whether the
7803 channel has global users or not after given client was removed from
7804 the channel. It also checks whether the channel has local clients
7805 on the channel anymore. If it does not have then the channel entry
7806 is removed as it is not needed anymore.
7808 * The silc_server_notify now checks on JOIN notify whether the joining
7809 client is one of locally connected or global. If it is global then
7810 the channel has now global users on the channel and that is marked
7811 to the channel entry. Also, it now saves the global client to
7812 global list who is joining and JOINs it to the channel. This is
7813 for normal server, that is.
7815 Changed silc_server_send_notify_on_channel,
7816 silc_server_packet_relay_to_channel and
7817 silc_server_packet_send_to_channel check if we are normal server
7818 and client has router set (ie. global client) do not send the
7819 message to that client, as it is already routed to our router.
7821 * Implemented LEAVE notify type handling in silc_server_notify
7824 * Tested LEAVE command in router environment successfully. Tested
7825 with two routers, two servers and two clients.
7829 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
7831 * Implemented SIGNOFF notify type handling in silc_server_notify
7834 * silc_server_remove_id now removes the client entry from all channels
7835 it has joined and thusly sends SIGNOFF notify type.
7837 * Rewrote the NAMES list generation in server by removing two excess
7838 loops. The lists are created now inside one loop.
7840 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7842 * silc_server_remove_channel_user checks now also global list
7843 for channel and client.
7845 * silc_server_new_channel_user checks now both local and global
7846 list for channel and client. Fixed a bug in client id decoding.
7847 Used to decode wrong buffer.
7849 * silc_server_channel_message checks now both local and global
7850 list for channel entry.
7852 * Tested channel joining (hence JOIN) in router environment
7853 successfully. Tested with two routers, two servers and two
7856 * Tested channel message sending in router environment successfully.
7858 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7860 * Added silc_server_save_channel_key into server.[ch] to save the
7861 received channel key in Channel Key payload processing. It is
7862 also used in JOIN command reply handling.
7864 Equivalent function silc_client_save_channel_key added into
7865 client.[ch] into client library.
7867 * Changed JOIN command reply to send information whether the channel
7868 was created or not (is existing already) and the channel key
7869 payload. Changed protocol specs accordingly.
7871 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
7872 the request was sent by ID and not by nickname. Crashed on
7875 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7877 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
7878 now correctly save the received data.
7880 * silc_server_free_sock_user_data now notifies routers in the
7881 network about entities leaving the network.
7883 At the same time implemented functions silc_server_remove_id
7884 and silc_server_send_remove_id to receive and send REMOVE_ID
7885 packets. The packet is used to notify routers in the network
7886 about leaving entities. The ID removed will become invalid in
7889 * Added function silc_idlist_del_server into server. Removes and
7890 free's server entry from ID list.
7892 * silc_server_private_message function now checks, if we are router,
7893 that the destination ID really is valid ID, naturally.
7895 * In router when NEW_ID packet is received (for new client) the
7896 hash of the Client ID is saved in the ID Cache but the
7897 client->nickname is set to NULL, instead of putting the hash
7900 IDENTIFY command now also checks that client->nickname must be
7901 valid. If it is not if will request the data from the server who
7902 owns the client. Added new function
7903 silc_server_command_identify_check.
7905 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
7906 to set the command to already allocated Command Payload.
7908 * Tested private message sending in router environment with two
7909 routers, two servers and two clients. Fixed minor bugs and now
7912 * Fixed segfault from client's NAMES command. Used to crash if
7915 * Forwarded packets must not be routed even if it is not destined
7916 to the receiver. Changed server code comply with this.
7918 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7920 * Added `require_reverse_mapping' boolean value to ServerParams
7921 structure. If TRUE (not default) the server will require that
7922 the connecting host has fully qualified domain name.
7924 If the reverse mapping is not required and hostname could not be
7925 found the IP address is used as hostname.
7927 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7929 * Implemented version string checking to both client and server.
7930 The check is incomplete currently due to the abnormal version
7931 strings used in development version of SILC.
7933 * Changed all command functions in server to use the new
7936 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7938 * Changed char *data to unsigned char *data in ID Cache system to
7939 support binary data as ID Cache data. Changed code to support
7940 binary data in lib/silccore/idcache.c.
7942 * Renamed silc_server_packet_relay_command_reply to
7943 silc_server_command_reply as it is normal packet receiving
7944 function. Rewrote the function to accept command replys for
7945 servers and not only for clients.
7947 * Mark remote router always as registered server if we are connecting
7948 to it. Otherwise, commands sent by the router to us are ignored.
7950 * All ID List find routines now returns the ID Cache Entry pointer
7951 as well if requested.
7953 * WHOIS command works now in router environment, tested with two
7954 routers, two servers and two clients.
7956 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
7957 in router environment (as it is almost equivalent to WHOIS) but
7958 hasn't been tested thoroughly. Added new functions:
7960 silc_server_command_identify_parse
7961 silc_server_command_identify_send_reply
7962 silc_server_command_identify_from_client
7963 silc_server_command_identify_from_server
7965 * Disabled route cache adding because adding two different ID's with
7966 same IP replaces the old cache entry thus giving wrong route.
7967 The entry->router->connection is always the fastest route anyway
7968 so route cache may not be needed. Of course, new routes maybe
7969 established after receiving the ID when the entry->router->connection
7970 might not be anymore the most optimal.
7972 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7974 * Add route cache for received ID for fast routing.
7976 * Added silc_server_packet_route to route received packet on router
7977 that is not destined to us.
7979 * Renamed silc_server_get_route to silc_server_route_get.
7981 * Added id_string and id_string_len fields into SilcServer to
7982 include encoded ServerID for fast comparing without excess
7983 encoding of the ID's.
7985 * Cleaned up WHOIS command on server side. Added following static
7988 silc_server_command_whois_parse
7989 silc_server_command_whois_check
7990 silc_server_command_whois_send_reply
7991 silc_server_command_whois_from_client
7992 silc_server_command_whois_from_server
7994 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
7995 arguments in command replies. All command functions should be
7996 updated to use this macro.
7998 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8000 * Minor typo fixes on command reply handling on server.
8002 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8004 * Added silc_server_command_add_to_channel internal routine to add
8005 the client to the channel after router has created the channel and
8006 sent command reply to the server.
8008 * Added generic silc_server_send_command to send any command from
8011 * Use static buffer with ID rendering instead of duplicating data.
8013 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8015 * Fixed a channel user mode bug when joining to a channel server gave
8016 everybody channel founder rights, oops.
8018 * We mark ourselves as the router of the incoming server connection
8019 if we are router ourselves. This way we can check in some packet
8020 sending functions whether it is locally connected server. For
8021 incoming router connections we put NULL.
8023 * For router sending packets locally means now always sending the
8024 packet cell wide; to local clients and local servers. For normal
8025 server sending packet locally means sending it to only local
8028 * Fixed the JOIN command to really work in router environment. If the
8029 channel is created it is always created by the router. Router is
8030 also responsible of making the initial joining to the channel,
8031 sending JOIN notify to the sending server and distributing
8032 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
8033 does not exist server doesn't do anything else but forward the
8034 command to the router which performs everything.
8036 * Added silc_server_send_channel_key function to send the Channel Key
8039 * Added silc_server_create_channel_key to create new channel key. The
8040 channel key is now re-generated everytime someone joins or leaves
8041 a channel, as protocol dictates. Note: channel->key_len is the
8044 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8046 * Splitted server.[ch] finally. Created now packet_send.[ch] and
8047 packet_receive.[ch] to separate packet sending and receiving
8048 routines. The server.[ch] now includes everything else including
8049 actual packet processing (writing and reading data) and other
8052 Renamed silc_server_private_message_send_internal to
8053 silc_server_send_private_message. The routine is still though
8054 used only to relay private messages as server does not send
8055 private messages itself.
8057 Renamed silc_server_new_channel to silc_server_create_new_channel
8058 and added new function sicl_server_new_channel that handles the
8059 incoming New Channel packet. Added also new sending function
8060 silc_server_send_new_channel to send New Channel Payload.
8062 * Added new function silc_server_notify to process incoming notify
8063 packet to the server/router. Server may then relay the notify
8064 to clients if needed.
8066 * Added new function silc_server_new_channel_user to process incoming
8067 New Channel User packet. Router will redistribute the packet and
8068 send JOIN notify to its local clients and locally connected servers
8069 if needed. Normal server will send JOIN notify to its local client
8070 on same channel when received this packet. Added also corresponding
8071 sending function silc_server_send_new_channel_user to sent the
8074 * Added boolean route argument to send_notif_to_channel and
8075 packet_send_to_channel functions to attempt to route the packet
8076 if it is TRUE and send only locally if it is FALSE.
8078 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8080 * silc_server_replace_id now broadcasts the received replace ID
8081 packet if it is not broadcast packet already. The router must
8082 broadcast to inform other routers about changed ID.
8084 * Added backpointer to server's router into SilcServer context in
8085 silcd/server_internal.h.
8087 * Fixed silc_server_packet_broadcast to send correct broadcast
8090 * The channel key is now distributed to the local client as soon
8091 as it is received from the router (in router environment) so that
8092 no other packet may be sent for the channel until client has
8095 * silc_server_remove_channel_user now broadcasts the received
8096 Remove Channel User packet if it is not broadcast packet already.
8097 The router must broadcast to inform other routers about removed
8100 * Added users field into SilcPacketContext that is a reference count
8101 of the context. One can increase the reference count by calling
8102 silc_packet_context_dup which is now changed to just increase the
8103 reference count instead of duplicating the data. The reference
8104 count is decresed by calling silc_packet_context_free that will
8105 free the data after the reference count hits zero.
8107 For now on the packet context and everything allocated into it
8108 (including the raw packet from network) must be freed by calling
8109 the new silc_packet_context_free function. Added also new function
8110 silc_packet_context_alloc that must be used now to allocate the
8111 context. This also means that if a routine is asynchronous from
8112 silc_[client/server]_packet_parse_type the packet context must
8113 be duplicated by calling silc_packet_context_dup. Otherwise it
8114 gets free'd after silc_[client/server]_packet_parse_type returns.
8115 Also, one must remember that if packet is duplicated then its
8116 reference count must be decresed by calling the free function as
8117 many times as it was duplicated.
8119 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
8120 from both client and server.
8122 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8124 * Made joining to a channel working in router environment.
8126 * Cleaned up JOIN command on server side and create function
8127 silc_server_command_join_channel internal routine to make the
8130 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8132 * Changed silc_command_pending list to SilcDList. Also, added
8133 `ident' field to SilcServerCommandPending structure to identify
8134 the reply and to call correct callback.
8136 Added silc_server_command_pending_check function to replace the
8137 corresnponding macro. The silc_command_pending list is not
8140 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
8141 to set identifier to previously allocated Command Payload. It
8142 is used to set identifier for command when resending Command
8145 * Added silc_command_payload_encode_payload to encode Command
8146 Payload buffer from SilcCommandPayload structure.
8148 * Added silc_argument_payload_encode_payload to encode Argument
8149 payload buffer from SilcArgumentPayload structure.
8151 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8153 * Changed WHOIS command to support router connection on server side.
8154 The whois request is always sent to router unless the server is
8155 standalone server. After server has received the reply from the
8156 router will it send the reply to the client.
8158 * Added silc_server_packet_broadcast into silcd/server.[ch] to
8159 broadcast received broadcast packet. The function is used only
8160 by router. The broadcast packet is always sent to the router's
8163 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
8164 render given ID to printable string, for log files for example.
8166 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8168 * Made basic router to router connections working. At least they
8169 can now connect to each other but nothing really works the way
8170 they are supposed - yet.
8172 * Added new initiator token to RouterConnection configuration
8173 file in silcd/serverconfig.[ch]. It is used to tell whether we
8174 are the initiator to the remote router or whether we'll expect
8175 the other end to connect.
8177 * Moved registering of listener task to silc_server_init, hence
8178 the server starts listenning as soon as it is run, even if it
8179 does not have connections to other routers. Let's see how well
8182 * Changed default connection retry timeouts for more suitable in
8185 * Removed cipher and such arguments from silc_idlist_add_client
8186 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
8187 Added new function silc_idlist_add_data to add the keys and stuff
8190 * Added SilcIDListData structure and added it to SilcClientEntry
8191 and SilcServerEntry as their first field in the structure. This
8192 way we can explicitly cast the ID entries to the SilcIDListData
8193 structure and get common data for the entries. In past, we had
8194 to first check what type of connection it is and then cast it to
8195 correct ID entry type. Now, we can directly cast the opaque
8196 pointer to the SilcIDListData (no matter what ID entry it actually
8197 is) and get the data needed.
8199 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8201 * Wow, found a bug in scheduler. The scheduler uninitialized itself
8202 in some circumstances even if threre were timeout tasks, though not
8203 IO tasks, but tasks anyway. Now fixed.
8205 * Defined SilcServerConnection structure to hold connection specific
8206 stuff about directly connected servers and routers. The definition
8207 is currently in silcd/server_internal.h. I thought about having
8208 a bit more important role fro this struct but for now it is used
8209 only when connecting to other server (or router actually).
8211 * Added connecting retry support in server when connecting to
8212 router(s). The retry feature implement exponential backoff
8213 algorithm. Also, added SilcServerParams structure to hold default
8214 parameters for server. For now, it include these retry settings
8215 and are hard coded. After server is moded to be as Silc Server
8216 Library this structure will be more important.
8218 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8220 * Changed client librarys channel->clients table to SilcList and
8221 changed code accordingly.
8223 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8225 * Changed client's channel table to SilcList and changed code
8226 accordingly. Also changed SilcChannelClientEntry to include back-
8227 pointer to the channel so that client entry can use that structure
8228 as list as well and we have fast cross-reference to the channel.
8229 This change dramatically decreased the complexity of channel
8230 handling with client entry and vice versa (removed one extra
8231 loop when searching for channel entry from many functions).
8233 * Changed server->sim from table to SilcDList and changed code
8236 * NAMES command can now be used from user interface. It will show
8237 the user list on the channel, neatly.
8239 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
8240 Code now saves realname of the user if it becomes available.
8242 * Renamed configure.in to configure.in.pre and made ./prepare
8243 script to automatically add correct version string to
8244 configure.in which it creates from configure.in.pre.
8246 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8248 * NAMES command reply now shows users mode with the nickname when
8251 * Moved silc_client_ch[u]mode[_char] functions from
8252 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
8253 place sucks, they are utility functions and should be in some
8256 * Fixed some unsigned int's to unsigned short's. Patch by cras.
8258 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
8261 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8265 * Added TRQ (efficient deque and list library) into lib/trq. This is
8266 a very good list library that is currently used in the SILC. Defined
8267 SilcList API over the library because I didn't like the API very
8268 much. See lib/trq/silclist.h for the API and examples of how to
8269 use the API. Fixed various places in the code to use the new
8270 SilcList API. The SilcList is meant for lists that has a structure
8271 already defined as a list. It is not suitable to add just some
8272 context to the list (in TRQ, the context is the list actually).
8274 So, I defined SilcDList that can be used for the purpose where
8275 predefined list structure does not exit. This can be used as
8276 such list. Now some context just can be added to the SilcDList.
8277 Currently this list is not used in the SILC just yet, though there
8278 are a lot places where this can replace dynamically allocated
8279 tables and I will fix these places, later, to use SilcDList.
8280 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
8281 and use TRQ internally).
8283 Also fixed some annoying warning messages that the original TRQ
8284 code generated. Also minor changes to TRQ's Makefile.in.
8286 * Added support for querying by Client ID to both WHOIS and
8287 IDENTIFY commands into server, as required by the protocol.
8289 * Removed method function pointers from SilcBuffer structure. They
8290 weren't used to anything and just increased the context size for
8291 no good reason. This change also made silc_buffer_alloc and
8292 silc_buffer_free functions inline functions.
8294 * Disabled command flooding detection support until it's fixed so
8295 that it accepts commands in but does not execute them more than once
8298 * Added silc_net_localhost(), to return local hostname, into
8299 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
8300 that must be initialized before calling silc_client_init.
8302 * Added new function: silc_server_send_notify_on_channels to send
8303 notify messages to all channels client has joined. It is assured
8304 that the message is sent only once per client.
8306 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
8307 lib/silcutil/silcutil.[ch] as silc_format function. The new
8308 function is generic and is used by server as well, not only by
8309 the logging routines.
8311 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
8312 the provided version string was not acceptable. Added new function:
8313 silc_ske_check_version into lib/silcske/silcske.h. The function
8314 must be implemented by the application (client or server) and it
8315 does not reside in the SKE library. The function checks the version
8316 string remote end sent.
8318 * Added back pointers (to opaque context and to SilcSocketConnection)
8319 into SilcPacketContext structure into lib/silccore/silcpacket.h.
8321 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
8322 duplicate packet context structure.
8324 * Changed `notify' client operation to send same arguments as client
8325 receives from server except for ID's. ID's are mapped to correct
8326 ID entry and that is returned. Also, if channel entry is not sent
8327 by server but the notify is for channel the channel entry is sent
8328 to application (otherwise application doesn't know that it is for
8329 channel (library gets it from packet's Destination ID)).
8331 * Added silc_client_remove_from_channels into client library to
8332 remove a client from all channels it has joined to. Used when
8333 received SIGNOFF notify from server. Added also new function
8334 silc_client_replace_from_channels to replace old ID entry with
8335 new ID entry on all channels. Used when received NICK_CHANGE
8338 * Fixed ID Cache list handling in silc_idlist_get_client in
8339 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
8340 to get (or query) client by ID.
8342 * Updated TODO list.
8344 * Added connection authentication status message defined by the
8345 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
8346 support for these into the code in client and server side.
8348 * Added generic function silc_client_send_command to send any command
8349 with variable argument list. Application should use this function
8350 to send commands if the command functions provided by the library
8351 does not suite for the application's user interface needs.
8353 * Added new `failure' client operation. Application is notified about
8354 received failure packet if client is executing a protocol. In this
8355 case the protocol's execution has failed.
8357 * Added SKE's end notify to send the SKE_SUCCESS notify message that
8358 is required by the protocol.
8360 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
8361 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
8364 * Added status flag to SilcSKE object to indicate realtime status
8365 of the SKE protocol.
8367 * Application receives now exactly same command reply arguments as
8368 the library receives from server. However, if ID is received the
8369 corresponding ID entry is returned to the application (eg. Client
8370 ID is mapped to correct SilcClientEntry entry and that is returned).
8371 Changed command_reply client operation due to this change.
8373 * Changed all ID's in commands and in command replys as ID Payloads.
8374 Change affected both client and server side codes.
8376 All ID's sent in SILC network (with execption of ID's in SILC
8377 Packet header) are sent in ID Payload to support variable length
8380 * Server now notifies nick changes and notifies all clients on
8381 the channels about the new nickname (about the new Client ID,
8384 * Implemented CMODE command to change channel modes. Supports all
8385 channel modes defined by the protocol specs except ban and invite
8386 lists. (Also, private channel key mode is supported but support for
8387 setting private channel key in client is missing, thus, this mode
8388 has no effect on client side (except that server requires that the
8389 client uses private channel key and normal channel traffic does not
8392 Also, invite mode works per se, but INVITE command does not work
8393 yet correctly, so you can set channel as invite only channel but
8394 inviting clients to the channel does not work (it is yet to be
8395 thought what's the best way to do it).
8397 * Added new command SILC_COMMAND_CUMODE to change user mode on the
8398 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
8399 Implemented CUMODE command to change user's mode on the channel.
8400 Supports all modes defined by the protocol specs.
8402 * Added NAMES command reply to return users modes on the channel.
8404 * Removed unnecessary and slow ciphers from lib/silccrypt.
8406 * Set SO_KEEPALIVE option to connection sockets by default.
8408 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
8410 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
8411 redefined the Notify Payload into protocol specs.
8413 * Added silc_id_payload_parse_id to get ID directly from raw
8416 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8418 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
8419 accept searching by Client ID as well.
8421 * Added support for LEAVE and SIGNOFF notify types in client library.
8423 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
8424 to parse ID Payload from raw data.
8426 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8428 * Added flags parameter into silc_ske_assemble_security_properties
8429 function in lib/silcske/silcske.[ch].
8431 * Changed notify client operation to fit better for notify messages
8432 sent by server. The notify payload received from server is now
8433 passed to the application (after parsing it to SilcNotifyPayload).
8434 It is application's responsibility to retrieve the arguments
8435 from the payload and show the message the way it wants. The message
8436 sent by server is implementation specific.
8438 * Changed public keys to comply with the protocol specification.
8439 Old public keys are not supported anymore and are not compatible.
8441 * Removed nickname from Channel Payload as the latest draft removed
8442 it. The client must resolve the nickname from the NAMES command
8443 reply received when it joined the channel.
8445 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
8447 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8449 * Fixed some errors in protocol specification drafts.
8451 * Created lib/silccore/silcnotify.c to implement Notify Payload
8452 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
8453 generic payloads described by protocol specifications. The file
8454 includes implementations for ID Payload and Argument Payload.
8456 * Changed Command Payload implementation to use the new Argument
8457 Payload. Changed command_xxxx_payload to command_payload_xxxx
8458 to comply with SILC coding conventions.
8460 * Added suppport for Argument Payload handling in Notify Payload
8461 implementation as protocol requires it. Added the new support
8462 into server and client lib as well.
8464 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8466 * Added support for multiple nicknames on same channel. [n] is
8467 added locally to the nickname if there are more than one same
8468 nicknames on the channel.
8470 * Server now sends all nicknames that matched WHOIS request.
8471 Client also shows the list received from server.
8473 * Added TOPIC command to client side. User can now set and show
8474 current topic on channel.
8476 * Added MOTD command to client and server. Also, server sends the
8477 motd when client connects to the server.
8479 * Changed version strings to comply ISO 8601.
8481 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8483 * Fixed protocol error handling in client library. It should now
8484 cope even if the SKE fails for some reason.
8486 * Made new protocol specification drafts for submitting to IETF.
8488 * Implemented TOPIC command to server in silcd/command.c.
8490 * Added two new notify types into lib/silccore/silcnotify.h:
8491 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
8492 notify nickname change and topic setting/change on a channel.
8494 * API change of command_reply operation in client library. The
8495 application gets now the status type received from server as well.
8497 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8499 * Removed the function just added to lib/silcutil/silcschedule.[ch].
8501 * Cras fixed and optimized the packet handling even further and
8502 it should work now. Minor change to the prototype of function
8503 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
8505 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8507 * Added new function into lib/silcutil/silcschedule.[ch]:
8508 silc_schedule_with_fd to select() a specified fd. The function
8509 returns after timeout expires or data arrives or goes. The
8510 function is used by packet routines to wait that all data is
8511 received from network.
8513 * Fixed data reading from network in lib/silccore/silcpacket.c.
8514 The code now assures that all data is read from the fd and then
8515 continues packet processing. This was a bug fix since the code
8516 used to drop some data in some circumstances.
8518 * Added new function into lib/silcclient/client.[ch]:
8519 silc_client_start_key_exchange to start key exchange after
8520 connection has been established to server. The code internally
8521 now uses this funtion but its main purpose was to provide it
8522 for applications that perform their own connecting. After
8523 application has created a connection it merely calls this
8524 function to start the key exchange between client and server.
8525 The library takes care of everything else after that.
8527 Updated also lib/silcclient/README to explain the usage of
8530 * Do not send to application information that connection has
8531 been established. Application gets notified it by connect
8534 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8536 * Applied cras's patch to add silc_schedule_one function. The
8537 function runs scheduler once and returns.
8539 * Fixed the scheduler after cras messed it up. The timeout
8540 handling works now as it's supposed to work.
8542 * Added into lib/silccore/ silcnotify.h to include notify
8543 message types support. Changed silc_server_send_notify*
8544 functions, in server.[ch], to support those new notify types.
8545 Added the support for the notify types into client library,
8546 as well. Added new notify client operation into ops.h in
8549 * Changed silc_server_packet_send_to_channel to send normal
8550 packets instead of just channel message packets. The function
8551 is now used to send the notify packets to channels. It is not
8552 used to send channel message packets anymore, as server never
8555 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
8556 va_arg()s as it seems to require it nowadays. I guess, if SILC
8557 is compiled with older va_arg() the new code should work anyway.
8559 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8561 * Splitted core library. Core library (lib/silccore) includes
8562 now only SILC protocol specific core (and common) components.
8563 Created new utility library (lib/silcutil) that includes more
8564 generic purpose stuff. The stuff for util library was taken
8565 from the old core library. This was minor and easy split.
8567 * Created SILC Client Library (lib/silcclient) that includes
8568 implementation of the SILC client without user interface. This
8569 was major move from silc/ directory. The code has been changed
8570 so that it is transparent towards the user interface. The
8571 silc/ directory includes now the same user interface as before
8572 and it uses the new client library. Read lib/silcclient/README.
8573 Basicly, the client library performs everything else related
8574 to SILC except user interface handling. Also, configuration
8575 files are considered to be part of user interface and library
8576 does not handle them.
8578 This change also changed a lot of structures, function naming etc.
8579 Most important change was that SilcClientWindow object was
8580 renamed to SilcClientConnection in the client library. Created
8581 also new file lib/silcclient/ops.h. Also added new files
8582 silc/local_command.[ch] and silc/client_ops.[ch].
8584 All these changes were made to make it easier for user interface
8585 designers to create what ever user interface for the SILC client
8588 It is also expected that the server will be moved to lib
8589 directory as well and SILC Server Library will be created;
8590 sometimes in the future.
8592 * Removed Local commands from lib/silccore/silccommand.h as
8593 they are application specific and new client library does not
8594 handle any of those anymore.
8596 * Several functions moved to lib/silcutil/silcutilc.[ch] from
8597 old client implementation in silc/.
8599 * Added support for callback functions in SILC_LOG_* macros.
8600 Application can now set its own callbacks that will be called
8601 instead of using the default functions that will always print
8602 the debug messages to stderr (or stdout). Also, debugging can
8603 now be disabled by setting silc_debug to FALSE and re-enabled by
8604 setting it to TRUE. Note, that logging will still work even
8605 if debugging is disabled.
8607 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
8608 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
8609 silc_log_reset_debug_callbacks.
8611 * To enable debugging in silc client one must give now -d
8612 option on command line.
8614 * Changed silc_schedule_init to automatically allocate task queues
8615 if they are not allocated before calling it.
8617 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8619 * Added GMP 3.1 into math library.
8621 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8623 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
8624 a channel in SILC network. The packet is used by servers and
8625 routers to notify other routers that user has left a channel.
8626 This little feature was missing until now. Added the feature
8627 to protocol specification as well.
8629 Added functions: silc_server_send_remove_channel_user and
8630 silc_server_remove_channel_user into server.[ch].
8632 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
8633 lib/silccore/silcpacket.h. However, they are not implemented
8636 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8638 * Fixed joining to a channel and sending channel messages
8639 between server and router. The channel message sending should
8640 now work inside a cell.
8642 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8644 * Fixed the private message sending between server and router.
8645 The private message sending should now work inside a cell.
8647 * Added silc_server_replace_id into server.[ch] to replace
8648 existing ID in the SILC network.
8650 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
8651 and silc_idlist_replace_server_id into idlist.[ch] in server.
8653 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8655 * Fixed the server to server connections. Server can again now
8656 connect to router. Router to router connections probably does
8659 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8661 * Added dynamic protocol registering support. Now protocols can
8662 registered and unregistered on the fly. Patch by cras.
8664 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8666 * Added lib/contrib directory to hold routines that some platforms
8667 don't have but are needed by SILC.
8669 * Added getopt.c, getopt1.c and getopt.h from GNU C library
8670 into lin/contrib to provide getopt() and getopt_long() for
8671 those who don't have it.
8673 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8675 * Added AWAY command to client. When away message is set and
8676 client receives a private message packet the client automatically
8677 replies to the sender with the away message.
8679 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
8680 bug seemed to be the cause of recent problems when compiling
8683 * Added version detection support to SKE protocol specification
8684 and added the new changes to the SKE implementation as well.
8685 There were other minor changes in the SKE protocol as well.
8687 Many changes in lib/silcske/silcske.[ch] and in
8688 lib/silcske/payload.[ch].
8690 * Added ^U functionality, clear input line. Patch from cras.
8692 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8694 * Mainly small bugfixes on core library. Fixed some debugging
8695 logging and buffer overflow in silclog.c.
8697 * Updated config.sub and config.guess on the distribution tree.
8699 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8701 * Added command lagging support in server. Client may execute
8702 commands now only once in two seconds.
8704 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8706 * Optimized packet reception. MAC computation and checking is now
8707 also more optimized. A lot previously duplicated code is now
8708 used as generic by both client and server.
8710 * Fixed key pair generation in clientutil.c
8712 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8714 * Added into lib/silccore/silcbufutil.[ch] new function;
8715 silc_buffer_realloc.
8717 * Moved generic packet sending/encryption functions to
8718 lib/silccore/silcpacket.[ch] from client and server. Some
8719 rewriting of the functions.
8721 * Moved all generic packet reception/decryption functions to
8722 lib/silccore/silcpacket.[ch] from client and server. The
8723 packet processing is now much cleaner in both client and server.
8724 These were major changes in both client and server.
8726 * Created many common functions in server to do packet sending.
8727 Previously code were duplicated a lot, this has been removed
8730 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8732 * Rewrote major parts of the ID cache system. Don't know
8733 whether it is better now or not but at least the API is more
8736 * Major rewrite on ID cache stuff on client because of the ID
8737 cache API changes. Added idlist.c to client.
8739 * Also major rewrite on ID cache stuff on server as well.
8740 Major rewrite of idlist.[ch]. SilcXXXList's are now named
8741 SilcXXXEntry's. We won't keep anymore idlist specific pointers
8742 in hand, instead they are all put into the ID cache system now.
8743 All server_idlist_* routines uses ID cache now instead of
8744 traversing its own lists (those lists does not exist anymore).
8745 SilcIDList though still exists. Also, SilcXXXEntry's are
8748 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8750 * Finally made the SKE implementation compliant to the protocol
8751 specification. All mp integers are now binary encoded as
8752 opposed being HEX encoded.
8754 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
8757 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
8758 functions: silc_[encode/decode]_pem. Also added function
8759 silc_encode_pem_file to PEM encode with newlines ('\n') for
8762 * SILC public keys are now encoded either PEM or binary. Same
8763 option is for private keys as well. By default private keys
8764 are binary encoded and public keys PEM encoded. Silly HEX
8765 encoding were removed.
8767 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
8768 function to create fingerprints.
8770 * Fixed a bug in SHA1; does not change the original data anymore.
8772 * Partly implemented INFO command on client and server side.
8773 Fixed CLEAR command. Changes to SERVER command; show current
8774 server(s) when giving command without arguments. Added
8775 VERSION command to client.
8777 * Added check to server that unregistered connections cannot
8778 execute commands (unless it is specificly allowed).
8780 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8782 * Fixed screen refresh.
8784 * Fixed channel joining bug from client. On some circumstances
8785 client tried to join to a channel it had already joined.
8787 * Added public key verification process into client's protocol.c.
8788 The client now verifies the public key from user and saves
8789 it into ~./silc/serverkeys/ directory.
8791 Added into: clientutil.[ch]: silc_client_verify_server_key.
8793 * Changed SKE protocol's silc_ske_initiator_finish function
8794 to accept callback function that verifies the received public
8795 key. Removed old silc_ske_verify_public_key function.
8797 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8799 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
8800 silc_pkcs_private_key[_data]_set.
8802 * Made the password and public authentication more cleaner in
8803 server's protocol.c.
8805 * Removed historic and obsolete protocol `channel_auth' from
8806 both client and server.
8808 * Removed wrong way of sending command status messages from
8809 server to client in server's command.c. The old way violated
8810 protocol specification.
8812 Changes to silccore/silccommand.[ch]: removed
8813 silc_command_encode_status_payload -> not needed anymore,
8814 changed silc_command_encode_payload_va to accept extra
8815 argument on variable argument list. The argument type must
8816 now be provided to the function. Also, added new function:
8817 silc_command_encode_reply_payload_va which is same as
8818 normal command_encode_payload_va except command status type
8819 is provided as extra argument.
8821 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8823 * Added ~./silc directory handling. The directory includes the
8824 public and private keys for the client.
8826 Added silc_client_check_silc_dir, silc_client_create_identifier
8827 and silc_client_load_keys.
8829 * Implemented SILC protocol compliant public key. Added public
8830 and private key saving to and loading from files.
8832 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
8833 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
8834 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
8835 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
8836 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
8838 Implemented: silc_pkcs_save_[public/private]_key[_data] and
8839 silc_pkcs_load_[public/private]_key.
8841 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8843 * Added silc_server_get_route (route.[ch]) to get connection
8844 data for the fastest route for given ID.
8846 * Implemented INVITE command on client and server. The command
8847 were re-defined in the SILC Protocol Specification and the
8848 implementation now complies with the specification.
8850 * Implemented PING command on client and server.
8852 * Implemented NAMES command on client and server. The server side
8853 supports currently only normal server not router server yet.
8854 Some changes to NAMES definition in SILC protocol specification.
8856 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8858 * Implemented LEAVE command on client and server.
8860 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
8861 again. This change was made to the protocol as well. Server
8862 should not violate the protocol specification anymore.
8864 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8866 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
8867 was tested. SOCKS4 was not but should work anyway.
